Referring to fig. 1, 2 and 4, an embodiment of the present invention provides a system 100 for producing fresh spring water in soft barrels. The soft barrel fresh mineral water production system 100 comprises a bottle blowing device 200, a filling and capping device 300, a boxing device 400, an aseptic conveying channel 500 and a compressed gas sterilizing filter 231.

The bottle blowing device 200 is used for producing the soft barrel 600.

The filling and capping device 300 is used to fill the soft tub 600 with fresh mineral water.

The boxing device 400 is used for boxing the soft barrel of fresh mineral water after filling.

The compressed gas sterilizing filter 231 is disposed in the gas supply channel of the bottle blowing device 200, and is used for sterilizing and filtering the compressed gas used by the bottle blowing device 200 in the bottle blowing process.

The sterile conveying channel 500 is arranged between the bottle blowing device 200 and the filling and capping device 300. The soft barrel 600 produced by the bottle blowing device 200 is conveyed to the filling and capping device 300 through the sterile conveying passage 500 for filling fresh mineral water. An FFU (Fan Filter Units) high-efficiency Filter unit is arranged inside the sterile conveying channel 500, and the sterile positive pressure environment of the sterile conveying channel 500 is maintained. It is understood that the soft barrel 600 prepared by the bottle blowing device 200 can be directly delivered to the filling equipment 300 without using the sterile delivery channel 500. For example, in the bottle blowing-filling-cap screwing integrated equipment, the soft barrel 600 prepared by the bottle blowing device 200 can also be directly conveyed to the filling equipment 300 for filling fresh mineral water.

In the fresh mineral water production system 100 of soft barrel provided by the embodiment, a negative pressure fresh-locking soft barrel packaging container with stable quality and good compressibility is provided. The soft barrel is blown by the bottle blowing device 200, and fresh mineral water is filled and sealed by the filling and capping device 300 specially aiming at the soft barrel 600. The soft-barrel fresh mineral water production system can meet the production and filling requirements of the soft barrel 600, thereby being beneficial to improving the product quality of the soft-barrel fresh mineral water and the freshness of the water quality. In addition, in one of the embodiments, by providing the compressed gas sterilizing filter 231 in the gas supply passage of the bottle blowing device 200, the soft tub 600 is not easily affected by dust or bacteria in the outside air during the bottle blowing process, so that the freshness of the fresh mineral water in the soft tub 600 can be maintained. The soft barrel 600 is blown by a bottle blowing device and a bottle blowing process; the soft serve drum 600 is automatically transferred to the filling and capping device 300 through the aseptic transfer tunnel 500 for the filling and capping process. That is, high quality fresh mineral water taken from underground deep rock is filled into the negative pressure freshness retaining soft barrel 600 in an aseptic and clean filling space, and capping is performed. Finally, the rear-section packaging of the soft barrel of fresh mineral water is carried out in the boxing device 400. That is, by providing the aseptic transfer passage 500 between the bottle blowing device 200 and the filling and capping device 300, the soft tub 600 is not easily affected by dust or bacteria in the outside air from the manufacturing to the completion of the filling, so that the freshness of the fresh mineral water in the soft tub 600 can be maintained.

It should be noted that, in this embodiment, the soft barrel 600 is a negative pressure fresh-locking soft barrel. The negative pressure freshness retaining soft barrel 600 can be sufficiently compressed in the axial direction of the barrel body. When the negative pressure fresh-locking soft barrel 600 is used, the negative pressure fresh-locking soft barrel 600 can be continuously compressed along the axial direction of the barrel body under the action of the atmospheric pressure along with the continuous outflow of drinking water in the containing cavity inside the negative pressure fresh-locking soft barrel 600. The arrangement mode can prevent the outside air from entering the negative pressure fresh-locking soft barrel 600 in the process of flowing out the drinking water, so that the fresh quality of the water in the negative pressure fresh-locking soft barrel 600 is guaranteed. That is, in the negative pressure fresh-locking soft barrel 600, the fresh mineral water in the soft barrel maintains a state of zero air contact. That is, in the using process, the negative pressure fresh-keeping soft barrel 600 takes water and the barrel body begins to shrink, and no outside air enters the barrel to contact with the water until the water in the barrel is completely discharged. The negative pressure state can be kept in the barrel in the mode, so that the outside air cannot enter the barrel to be contacted with water, and the water in the barrel is prevented from being polluted by microorganisms carried by the outside air and dust.

The negative pressure fresh-locking soft barrel 600 may be made of one or more of PET (Polyethylene terephthalate), HDPE (high density Polyethylene), PP (polypropylene), PEN (Polyethylene naphthalate), and PEF (Polyethylene furan dicarboxylate), as needed. In this embodiment, the negative pressure freshness-retaining soft barrel 600 is made of PET material.

Therefore, when the negative pressure fresh-locking soft barrel 600 is used, the water in the soft barrel 600 keeps the air in a zero-contact state, so that the freshness of the fresh mineral water in the soft barrel 600 is ensured. However, in the existing production process of PET hard barrels or PC barrels, the produced PC barrels are usually exposed to the external environment, and before filling, the barrels are sterilized through a sterilization process and then conveyed to a filling device for drinking water filling. In the process, the produced PET hard barrel or PC barrel is easily influenced by bacteria and dust in the external environment, so that the freshness of water quality cannot be guaranteed. However, for the PET hard barrel or the PC barrel, since the subsequent water intake process is realized by air replacement, the water quality in the water intake barrel is very easily affected by the external environment. However, the negative pressure freshness-retaining keg 600 used in this embodiment is to ensure the freshness of the fresh mineral water in the keg 600 during use, so that the freshness of the water quality during production is ensured. However, the packaging characteristics and the production process of the existing PET hard barrel and PC barrel can not meet the requirement of the soft barrel for fresh mineral water on water freshness. Accordingly, the soft serve fresh mineral water production system 100 according to the embodiment of the present invention is provided to solve the above-mentioned problems.

In one embodiment, the bottle blowing apparatus 200 includes a conveying rail 210, a heating device 220, and a bottle blowing mechanism 230. The bottle blowing device 200 may further include a sterilization device 291 and an ion dust collector 292, as required. The sterilization device 291 is used for performing ultraviolet sterilization on the bottle embryo mouth. The ion dust removing device 292 is used for performing ion dust removal on the bottle blank 700.

Referring to fig. 3, 5 to 7, a bottle blank 700 is disposed on the conveying track 210. Specifically, the bottle blank is a semi-finished product which is formed by filling raw materials into a gun mold of a mold at a specific temperature and pressure and performing injection molding. The bottle blank becomes the end product after blow molding processing. In this embodiment, after the bottle blank 700 is processed by bottle blowing, the negative pressure fresh-keeping soft barrel 600 is formed.

The heating device 220 is used for heating the bottle blanks 700 on the conveying track 210. In this embodiment, the heating device 220 is an infrared heating lamp. The bottle blank 700 is irradiated by an infrared heating lamp, and the blank body part of the bottle blank 700 is heated and softened, so that the subsequent bottle blowing operation is performed. In order to maintain the shape of the bottle mouth, the bottle preform mouth is not heated and needs to be cooled by a cooling device.

The bottle blowing mechanism 230 is used for performing bottle blowing processing on the heated bottle blank 700. In the bottle blowing process, the heated bottle blank 700 is usually placed in a prepared mold, and then the bottle blank is blown by compressed air to stretch the bottle blank 700 into a desired shape, thereby forming the negative pressure freshing barrel 600. The bottle blowing process is carried out between the glass transition temperature and the crystallization temperature of the bottle blank 700, and is generally controlled to be between 90 and 120 ℃. In this region, the PET material of the preform 700 is in a highly elastic state, and is rapidly blow molded, cooled and set to form a transparent soft barrel. According to the requirement, the bottle blowing treatment process can be carried out in two steps:

pre-blow process (primary blow): the heated preform 700 is primarily stretched in the radial direction to substantially form the dimensions of the soft barrel 600 in the radial direction.

Blowing process (secondary blow): the heated bottle preform 700 is stretched in a transverse direction to be fitted on the inner wall of the mold, thereby forming the shape of the soft tub 600.

In the bottle blowing process, the overall distribution condition of the material influences the quality of the blown bottle. The temperature distribution of the bottle preform 700, the stretching start time and stretching speed of the compressed air blowing rod during the bottle blowing process, the pre-blowing start and end time, the pre-blowing pressure, the pre-blowing air flow and the like may all affect the material distribution of the bottle preform 700 during the bottle blowing process, thereby affecting the bottle blowing quality of the soft barrel 600. In particular, the overall temperature distribution of the preform 700 and the temperature gradient of the inner and outer walls of the preform 700 have a large influence on the quality of blown bottles. If the bottle preform 700 is softened to an insufficient degree at a low temperature, it is not easily blown into a desired shape. If the temperature of the bottle blank 700 is high, the orientation of the PET molecular chains in the PET material is insufficient in the stretching process, so that the body of the soft barrel 600 is whitish.

Referring to fig. 8, in order to match the temperature distribution of the bottle blank 700 with the requirement of the bottle blowing process of the soft barrel 600, in one embodiment, the heating device 220 includes a heating area a1 and a heat preservation area B1.

The heating area a1 is disposed on the side of the bottle blank 700. The heating zone a1 includes multiple sets of heating heat sources 221. The plurality of sets of heating sources 221 are arranged along the extending direction of the bottle blank 700.

The heat-insulating region B1 is disposed below the bottom of the bottle blank 700. The heat-insulating region B1 includes a first heat-insulating pipe 2221 and a second heat-insulating pipe 2222. The first heat preservation pipe 2221 is disposed near the bottom side of the bottle blank 700. The second insulating tube 2222 is disposed away from the bottom side of the bottle blank 700.

During the heating process of the bottle blank 700, the heating source 221 of the heating zone a1 is operated to heat-treat the bottle blank 700. The heating power ratio of the first heat preservation pipe 2221 in the heat preservation area B1 is smaller than the heating power ratio of the second heat preservation pipe 2222, so as to perform heat preservation treatment on the bottle blank 700. In this embodiment, the first heat preservation pipe 2221 in the heat preservation area B1 does not operate, and the second heat preservation pipe 2222 operates to preserve heat of the bottle blank 700.

In this embodiment, the heating device 220 is a heating lamp box, which includes a box 223, and a plurality of sets of heating sources 221 and a plurality of sets of heat preservation pipes 222 disposed in the box 222. In the process of conveying the bottle blanks 700, the bottle openings of the bottle blanks 700 face upward, the bottle bottoms face downward, and the bottle blanks are rotationally conveyed along the movement direction of the conveying track 210. At this time, the plurality of sets of heating sources 221 are arranged in sequence from top to bottom. The heating area a1 of the heating apparatus 220 is located above the soaking area B1 of the heating apparatus 220. In one embodiment, the distance between the centers of the two adjacent groups of heating sources 221 of the heating device 220 is in the range of 1-3cm, and the distance between the centers of the two adjacent groups of heating sources of the heating device is preferably 2cm and 1cm, so that the bottle blanks 700 can be heated. Specifically, in the present embodiment, the heating source 221 is made of an infrared heating lamp tube. Each group of infrared heating lamp tubes is controlled by a separate heating controller, so that the heating power turn-on ratio of each group of infrared heating lamp tubes can be independently adjusted.

In the bottle blowing device 200 for fresh mineral water soft barrel provided by the above embodiment, the heating device 220 is arranged to include a heating area a1 and a heat preservation area B1. The heating area a1 is disposed on the side of the bottle blank 700. The heat preservation area B1 is arranged on the bottom side of the bottle blank 700. The side surface of the bottom of the bottle blank 700 is provided with the heat preservation area B1, so that the temperature of the bottom and the blank body of the bottle blank 700 is more suitable for bottle blowing operation in the bottle blowing process. In addition, during the heating process of the bottle blank 700, the heating power ratio of the first heat preservation pipe 2221 in the heat preservation area B1 of the heating device 220 is smaller than the heating power ratio of the second heat preservation pipe 2222, so as to preserve the heat of the bottom and the blank body of the bottle blank 700. On the one hand, since the heating power ratio of the first thermal insulation tube 2221 disposed near the bottom of the bottle blank 700 is small, this way can prevent the temperature of the bottom and the body of the bottle blank 700 from rising too fast. On the other hand, because the heating power ratio of the second heat preservation pipe 2222 disposed away from the bottom side of the bottle blank 700 is relatively large, the bottom and the blank body of the bottle blank 700 in the heating region are three-dimensionally heat preserved by utilizing the upward hot air principle, so that the situation that the bottom and the blank body of the bottle blank 700 are heated unevenly is avoided.

In one embodiment, heating zone a1 of heating apparatus 220 includes a first heating heat source 2211, a second heating heat source 2212, a third heating heat source 2213, and a fourth heating heat source 2214. The first heating source 2211 is arranged corresponding to the embryo shoulder area of the bottle embryo 700. In this embodiment, the shoulder area of the bottle blank 700 is disposed below the finish support ring of the bottle blank 700. In the bottle blowing process, the shoulder area of the bottle blank 700 forms the barrel shoulder part of the negative pressure fresh-locking soft barrel 600. The second heating source 2212 is arranged corresponding to the upper area of the bottle blank 700. Specifically, the upper part of the preform body 700 is disposed adjacent to the shoulder region of the preform 700. In the bottle blowing process, the upper part of the body of the bottle blank 700 forms the upper part of the barrel body of the negative pressure fresh-locking soft barrel 600. The third heating source 2213 is disposed corresponding to the middle-lower region of the bottle blank 700. Specifically, in the bottle blowing process, the middle lower area of the body of the bottle blank 700 forms the middle lower part of the body of the negative pressure fresh-keeping soft barrel 600. The fourth heating source 2214 is arranged corresponding to the bottom area of the bottle blank 700. Specifically, in the bottle blowing process, the bottom area of the body of the bottle blank 700 forms the bottom portion of the negative pressure fresh-locking soft barrel 600. Since the bottle opening of the bottle blank 700 is arranged from top to bottom, the first heating source 2211, the second heating source 2212, the third heating source 2213 and the fourth heating source 2214 are also arranged in sequence from top to bottom. The first heating heat source 2211 is disposed at a top position; the fourth heating heat source 2214 is arranged at the bottom position; the second heating heat source 2212 and the third heating heat source 2213 are disposed between the first heating heat source 2211 and the fourth heating heat source 2214. In this embodiment, the third heating heat sources 2213 are two sets of heating heat sources, which are equally spaced between the second heating heat sources 2212 and the fourth heating heat sources 2214.

Specifically, during the heating process of the bottle blank 700 using the heating device 220:

the heating power ratio of the first heating heat source 2211 is greater than the heating power ratio of the second heating heat source 2212, the third heating heat source 2213 or the fourth heating heat source 2214; and/or the heating power ratio of the fourth heating heat source 2214 is greater than or equal to the heating power ratio of the third heating heat source 2213. In the present embodiment, the ratio of the heating power of the first heating heat source 2211 to the rated power of the heating heat source is between 40% and 55%; the ratio of the heating power of the second heating heat source 2212 to the rated power of the heating heat source is between 22% and 42%; the ratio of the heating power of the third heating heat source 2213 to the rated power of the heating heat source is between 20% and 40%. The ratio of the heating power of the fourth heating heat source 2214 to the rated power of the heating heat source is between 20% and 40%. In the present embodiment, the rated power of the heating heat source is in the range of 1800W to 3200W. The heating power ratios of the first heating heat source 2211, the second heating heat source 2212, the third heating heat source 2213 and the fourth heating heat source 2214 are set to the above form with the object of:

1. since the bottle blank 700 needs to be blown into the negative pressure fresh-locking soft barrel 600 in the subsequent bottle blowing process, the shape of the bottle opening of the bottle blank 700 should be maintained unchanged in the subsequent bottle blowing process. Therefore, during the heating process, a cooling liquid passage is usually provided near the mouth of the preform 700 to prevent the temperature of the mouth from being too high to deform. Due to the existence of the cooling liquid near the bottle opening of the bottle blank 700, the heating power ratio of the first heating heat source 2211 needs to be set to be greater than the heating power ratio of the second heating heat source 2212, the third heating heat source 2213 or the fourth heating heat source 2214, so as to offset the influence of the cooling liquid at the bottle opening of the bottle blank 700 on the overall temperature of the bottle blank 700. Meanwhile, the heating power of the first heating source 2211 is set to be higher, so that the evaporation of the liquid drops near the bottle opening of the bottle blank 700 is facilitated, and the influence of the corresponding liquid drops on the subsequent bottle blowing process is avoided.

2. Since the second heating source 2212 is arranged corresponding to the upper part of the bottle body of the bottle blank 700, the upper part of the bottle body of the bottle blank 700 corresponds to the upper part of the barrel body of the negative pressure fresh-locking soft barrel 600 in the bottle blowing process. Since the upper portion of the barrel body of the soft barrel 600 is disposed near the shoulder of the soft barrel 600, the stretching degree is large, and therefore, the heating power of the region needs to be set slightly larger to soften the partial region of the bottle blank 700.

3. Since the heating power ratio of the first heating heat source 2211 near the bottom of the bottle blank 700 is small, the fourth heating heat source 2214 disposed on the bottom side of the bottle blank 700 can increase the heating temperature once to achieve uniform heating of the bottle blank 700. On the other hand, since the bottom of the bottle blank 700 is not affected by the cooling water, the heating power ratio of the fourth heating heat source 2214 is not too high and does not exceed the heating power ratio of the first heating heat source 2211.

In fact, in the heating device 220, the heating sources 221 are disposed in the box 223 at equal intervals or close to equal intervals. Therefore, the number of the first heating heat sources 2211 of the heat-insulating region B1 may be set to 2-4 groups as appropriate; the number of the second heating sources 2212 of the heat-insulating region B1 may be set to 3-6 groups as appropriate.

In one embodiment, the heating device 220 has an oven temperature in the range of 50-70 ℃. The temperature of the preform 700 is in the range of 83-95 ℃. In the bottle blowing process of the bottle blowing mechanism 230, the bottle blowing air pressure is within the range of 15-25 bar; the draw ratio of the preform 700 was: the longitudinal stretch ratio of the preform 700 is in the range of 2.2-4.8; the bottle embryo 700 has a transverse stretch ratio in the range of 3.8-6.0. In this embodiment, the longitudinal stretch ratio of the bottle blank 700 refers to: the length of the stretched preform 700 is divided by the length of the preform 700 before stretching, and the unstretched neck finish dimensions are subtracted in the calculation of the stretch ratio. The transverse draw ratio of the preform 700 refers to: the stretched diameter of the preform 700 is divided by the diameter of the preform 700 before stretching. Too large a stretch ratio tends to cause stress whitening of the produced soft tub 600. Under the condition that the stretching ratio and the stretching speed are not changed, under the condition that the glass transition temperature of the blank material is not lower, the lower the stretching temperature is, the better the stretching temperature is, and the aim is to increase the straightening deformation and reduce the viscous deformation; the greater the stretching speed, the better, with the same stretching ratio and stretching temperature, since the higher the degree of molecular orientation of the PET chains; the larger the draw ratio, the better, with constant draw speed and draw temperature, also because of the higher degree of molecular orientation of the PET chains.

Specifically, in one embodiment, during the heating of the bottle blank 700:

the temperature of the middle lower area of the bottle blank 700 is higher than the temperature of the middle upper area of the bottle blank 700;

and/or the temperature of the middle upper area of the bottle blank 700 is higher than the temperature of the bottle shoulder area of the bottle blank 700.

Referring to fig. 9, in one embodiment, the bottle blowing device 200 further includes a preheating device 240. The preheating device 240 is used for preheating the bottle blanks 700 on the conveying track 210. The preheating device 240 and the heating device 220 are arranged in a line along the conveying direction of the conveying track 210. The preheating device 240 is disposed at a front end of the conveying rail 210. The heating device 220 is disposed at the rear end of the conveying rail 210. The bottle blanks 700 on the conveying rail 210 pass through the preheating device 240 and the heating device 220 and are then conveyed to the bottle blowing mechanism 230 for bottle blowing.

Referring also to fig. 10, in one embodiment, the preheating device 240 includes a plurality of preheating pipes 241. The plurality of preheating pipes 241 are arranged along the extending direction of the bottle blank 700. The preheating device 240 includes a heating area a2 disposed on the side of the bottle blank 700 and a heat preservation area B2 disposed on the bottom side of the bottle blank 700. The heat-retaining area B2 of the preheating device 240 includes a third heat-retaining pipe 2421 and a fourth heat-retaining pipe 2422. The third heat preservation pipe 2421 is arranged close to the bottom side of the bottle blank 700. The fourth heat preservation pipe 2422 is arranged far away from the bottom side surface of the bottle blank 700. During the preheating process of the bottle blank 700, the preheating pipe 241 of the heating area a2 of the preheating device 240 operates to heat-treat the bottle blank 700. The ratio of the heating power of the third heat-preserving pipe 2421 and the ratio of the heating power of the fourth heat-preserving pipe 2422 in the heat-preserving region B2 of the preheating device 240 are small, so that the bottom and the body of the bottle blank 700 can be heat-preserved. In fact, said preheating means 240 are provided for the purpose of: before the bottle blank 700 is heated, the bottle blank 700 is heated at a lower temperature, so that the bottle blank 700 is subjected to a preliminary heating and softening process.

In one embodiment, the heating zone a2 of the preheater 240 includes a first preheater tube 2411, a second preheater tube 2412, a third preheater tube 2413, and a fourth preheater tube 2414. The first preheating pipe 2411 is disposed corresponding to the shoulder area of the bottle blank 700. The second preheating pipe 2412 is disposed corresponding to the upper region of the preform body of the preform 700. The third preheating pipe 2413 is disposed corresponding to the middle-lower area of the preform body 700 of the preform 700. The fourth preheating pipe 2414 is disposed corresponding to the bottom region of the bottle blank 700. The second and third preheat tubes 2412 and 2413 are disposed between the first and fourth preheat tubes 2411 and 2414.

During the preheating of the bottle blank 700 using the preheating device 240:

the heating power ratio of the first preheating pipe 2411 is smaller than that of the second preheating pipe 2412 or the fourth preheating pipe 2414. In this embodiment, the ratio of the heating power of the first preheating pipe 2411 to the rated power of the heating heat source is between 9% and 29%; the ratio of the heating power of the second preheating pipe 2412 to the rated power of the heating heat source is between 20% and 45%; the ratio of the heating power of the third preheating pipe 2413 to the rated power of the heating heat source is between 20% and 40%; the ratio of the heating power of the fourth preheating pipe 2414 to the rated power of the heating heat source is 18% to 40%.

Since the preheating is performed to prevent the temperature of the bottle blank 700 from being too high and affecting the performance of the material, as mentioned above, the bottle opening of the bottle blank 700 is provided with a cooling groove, so that the initial temperature of the bottle opening of the bottle blank 700 is low. At this time, the heating power ratio of the first preheating pipe 2411 is made smaller than that of the second preheating pipe 2412 or the fourth preheating pipe 2414, so that the temperature at the bottle mouth of the bottle blank 700 does not change too sharply to affect the material performance during the preheating process. On the other hand, since the heating power ratio of the third heat preservation pipe 2421 near the bottom of the bottle blank 700 is small, the fourth preheating pipe 2414 disposed at the bottom side of the bottle blank 700 can raise the heating temperature for a while to achieve uniform heating of the bottle blank 700.

In one embodiment, the heating power ratio of the first preheating pipe 2411 is smaller than that of the first heating heat source 2211; and/or the heating power ratio of the fourth heat preservation pipe 2422 is the same as or similar to the heating power ratio of the second heat preservation pipe 2222. In one aspect, the heating power ratio of the first preheating pipe 2411 of the heating zone a2 is smaller than that of the first heating source 2211 of the heating zone a1, so as to preheat the bottle blanks 700. On the other hand, since the purpose of providing the heat-insulating region is mainly to insulate the bottom and body of the heated bottle embryo and to isolate the outside cold air from the outside of the heating device 220 or the preheating device 240, the heating power ratio of the fourth heat-insulating pipe 2422 of the heat-insulating region B2 is set to be the same as or substantially the same as the heating power ratio of the second heat-insulating pipe 2222 of the heat-insulating region B1, which can effectively achieve the heat-insulating function of the bottle embryo and the heating furnace.

In one embodiment, the bottle blowing device 200 for fresh mineral water soft barrels further comprises an air supply device 250. The air supply device 250 is disposed on the opposite side of the bottle blank 700 from the heating device 220. The air outlet of the air supply device 250 is arranged facing the bottle blank 700. A heating channel for allowing bottle blanks 700 arranged on the conveying track 210 to pass is formed between the air supply device 250 and the heating device 220.

In one embodiment, the conveying track 210 is provided with a cooling liquid channel. The cooling liquid channel is arranged close to the bottle opening of the bottle blank 700. When the bottle preform 700 is fixed on the bottle preform seat 211, the cooling liquid channel on the conveying track 210 is disposed near the bottle opening of the bottle preform 700, so as to reduce the temperature of the bottle opening of the bottle preform 700. In this embodiment, the cooling liquid is ice water.

The bottle blowing device 200 for the fresh mineral water soft barrel can also comprise a console according to the requirement. The console is used for controlling the whole fresh mineral water soft barrel bottle blowing device 200 to work according to a set program.

The working process of the fresh mineral water soft barrel bottle blowing device 200 is as follows:

the preforms 700 are transported into the conveying track 210. Specifically, the conveying track 210 is provided with a bottle blank seat 211. When the conveying track 210 is in operation, the bottle blank holder 211 is inserted into the mouth of the bottle blank 700, so that the bottle blank holder 211 and the bottle blank 700 are fixed together. According to the requirement, the surface of the bottle blank seat 211 contacting with the bottle mouth of the bottle blank 700 is provided with a convex elastic sheet. The elastic piece can strengthen the combination force between the bottle embryo seat 211 and the bottle embryo 700.

The conveying rail 210 is constantly moving, so as to drive the bottle blank 700 to rotate and move along with the conveying rail.

When the bottle blank 700 moves to the position of the preheating device 240, the preheating device 240 preheats the bottle blank 700.

After the preheating process is completed, the bottle blank 700 moves to the position of the heating device 220, and the heating device 220 performs the heating process on the bottle blank 700.

After the heating process of the bottle preform 700 is completed, the bottle preform 700 is conveyed to the bottle blowing mechanism 230 for bottle blowing. In the process of blowing, the bottle blank 700 is fixed in the mold of the bottle blowing mechanism 230. The outlet pipe is extended into the interior of the bottle blank 700 to perform a low-pressure pre-blowing action to produce the parison of the bottle. Then, the middle-pressure gas is introduced into the air outlet pipe to perform the second-step bottle blowing operation so as to form the shape of the soft barrel. And when the soft barrel is cooled, the soft barrel can be taken out from the mold.

The number of the heating means 220 or the preheating means 240 is not limited to one, and may be two or more, as needed. Referring to fig. 11, another embodiment of the invention provides a bottle blowing device 200 for fresh mineral water soft barrel. The bottle blowing device 200 for the fresh mineral water soft barrel comprises a conveying rail 210, a heating device, a bottle blowing mechanism 230 and a preheating device. The conveying track 210 is provided with a bottle blank seat 211. The preform seat 211 is used for fixing the preform 700. The heating device is used for heating the bottle blanks 700 on the conveying track 210. The bottle blowing mechanism 230 is used for performing bottle blowing processing on the heated bottle blank 700 to form a negative pressure fresh-locking soft barrel.

In the present embodiment, the heating means includes a first heating means 220 and a second heating means 260. The first heating device 220 and the second heating device 260 are sequentially arranged along the conveying direction of the conveying rail 210. The structure or shape of the first heating device 220 and the second heating device 260 is similar to that of the heating device 220 provided in the above embodiments, and is not described in detail here. The preheating devices include a first preheating device 240, a second preheating device 270, and a third preheating device 280. The first preheating device 240, the second preheating device 270, and the third preheating device 280 are sequentially arranged along the conveying direction of the conveying rail 210. In this embodiment, the bottle preform 700 sequentially passes through the first preheating device 240, the second preheating device 270, the third preheating device 280, the first heating device 220 and the second heating device 260, and then enters the bottle blowing mechanism 230 for bottle blowing.

In fact, when the heating device includes the first heating device 220 and the second heating device 260, since the second heating device 260 is disposed between the bottle blowing mechanism 230 and the first heating device 220, the heating power ratio of the second thermal-insulation tube in the thermal-insulation region of the second heating device 260 is greater than that of the second thermal-insulation tube in the thermal-insulation region of the first heating device 220, so as to perform the final preparation work before bottle blowing. In the present embodiment, the ratio of the heating power of the second thermal insulation tube 2222 in the thermal insulation region of the first heating device 220 to the rated power of the heating heat source is between 27% and 43%; the ratio of the heating power of the second heating heat source to the rated power of the heating heat source in the heat-insulating region of the second heating means 260 is between 38% and 55%.

In fact, when the preheating devices include the first preheating device 240, the second preheating device 270, and the third preheating device 280, the heating powers of the first preheating device 240, the second preheating device 270, and the third preheating device 280 may also be adjusted according to actual needs. For example, in winter when the room temperature is relatively low, the heating power of the second preheating device 270 may be increased by 10% to 24% as a whole; and the heating power of the third preheating device 280 is increased by 5% to 12% as a whole. It should be noted that when the heating power is increased, the phenomenon of blank whitening caused by overheating needs to be avoided. For another example, in summer with a relatively high room temperature, the heating power of the second preheating device 270 may be reduced by 5% to 12% as a whole; and the heating power of the third preheating device 280 is reduced by 10 to 24% as a whole. When the heating power is reduced, attention needs to be paid to avoid the phenomenon that the bottle blank is stretched and whitened due to the fact that the heating power is too low.

The bottle blowing device 200 further includes a compressed gas sterilizing filter 231 as required. The compressed gas sterilizing filter 231 is arranged in the compressed gas inlet passage close to the bottle blowing mechanism 230 and is used for sterilizing the compressed gas used by the bottle blowing mechanism 230 in the process of bottle blowing processing of the bottle blanks 700, so that the soft barrel 600 prepared by the bottle blowing mechanism 230 has higher degree of cleanliness. In this embodiment, the compressed gas sterilizing filter 231 is made of a borosilicate sterilizing filter element with a filtering precision of 0.2 μm. The sterilizing filter element has the advantages of high strength and long service life, and has higher filtering efficiency (LRV is more than 7/cm)²)。

In this embodiment, the conveying track 210 is provided with a bottle blank seat 211. The preform seat 211 is used for fixing the preform 700. The heating device 220 is used for heating the bottle blanks 700 on the conveying track 210. The bottle blowing mechanism 230 is used for performing bottle blowing processing on the heated bottle blank 700 to form a negative pressure fresh-locking soft barrel.

In this embodiment, the heating device 220 includes a plurality of sets of heating sources 221. The plurality of sets of heating sources 221 are arranged along the extending direction of the bottle blank 700. The heating device 220 includes a heating area a1 disposed on the side of the bottle blank 700 and a heat preservation area B1 disposed on the bottom of the bottle blank 700. The insulated area B1 of the heating device 220 includes a first insulated pipe 2221 and a second insulated pipe 2222. The first heat preservation pipe 2221 is disposed near the bottom side of the bottle blank 700. The second insulating tube 2222 is disposed away from the bottom side of the bottle blank 700. During the heating process of the bottle blank 700, the heating source 221 of the heating area a1 of the heating device 220 operates to heat the bottle blank 700. The heating power ratio of the first heat preservation pipe 2221 in the heat preservation area B1 of the heating device 220 is smaller than that of the second heat preservation pipe 2222, so as to preserve the heat of the bottom and the body of the bottle blank 700.

In one embodiment, before the heating process is performed on the bottle blank 700, the method further comprises the following steps:

step S204: preheating the bottle blanks 700 on the conveying track 210 by using a preheating device 240;

wherein the preheating device 240 and the heating device 220 are arranged in a conveying direction of the conveying track 210. The preheating device 240 is disposed at a front end of the conveying rail 210. The heating device 220 is disposed at the rear end of the conveying rail 210. The bottle blanks 700 on the conveying rail 210 pass through the preheating device 240 and the heating device 220 and are then conveyed to the bottle blowing mechanism 230 for bottle blowing.

In one embodiment, the preheating device 240 includes a plurality of preheating tubes 241 during the preheating process. The plurality of preheating pipes 241 are arranged along the extending direction of the bottle blank 700. The preheating device 240 includes a heating area a2 disposed on the side of the bottle blank 700 and a heat preservation area B2 disposed on the bottom side of the bottle blank 700. The heat-retaining area B2 of the preheating device 240 includes a third heat-retaining pipe 2421 and a fourth heat-retaining pipe 2422. The third heat preservation pipe 2421 is arranged close to the side surface of the bottom of the bottle blank 700. The fourth heat preservation pipe 2422 is arranged far away from the side surface of the bottom of the bottle blank 700. During the preheating process of the bottle blank 700, the preheating pipe 241 of the heating area a2 of the preheating device 240 operates to heat-treat the bottle blank 700. The heating power ratio of the third heat-preserving pipe 2421 and the heating power ratio of the fourth heat-preserving pipe 2422 in the heat-preserving region B2 of the preheating device 240 are small, so that the bottle blanks 700 and the heating furnace are subjected to heat-preserving treatment.

In one embodiment, heating zone a1 of heating apparatus 220 includes a first heating heat source 2211, a second heating heat source 2212, a third heating heat source 2213, and a fourth heating heat source 2214. The first heating source 2211 is arranged corresponding to the embryo shoulder area of the bottle embryo 700. In this embodiment, the shoulder area of the bottle blank 700 is disposed below the finish support ring of the bottle blank 700. In the bottle blowing process, the shoulder area of the bottle blank 700 forms the barrel shoulder part of the negative pressure fresh-locking soft barrel 600. The second heating source 2212 is arranged corresponding to the upper area of the bottle blank 700. Specifically, the upper part of the preform body 700 is disposed adjacent to the shoulder region of the preform 700. In the bottle blowing process, the upper part of the body of the bottle blank 700 forms the upper part of the barrel body of the negative pressure fresh-locking soft barrel 600. The third heating source 2213 is disposed corresponding to the middle-lower region of the bottle blank 700. Specifically, in the bottle blowing process, the middle lower area of the body of the bottle blank 700 forms the middle lower part of the body of the negative pressure fresh-keeping soft barrel 600. The fourth heating source 2214 is arranged corresponding to the bottom area of the bottle blank 700. Specifically, during the bottle blowing process, the bottom area of the bottle blank 700 forms the bottom portion of the negative pressure fresh-locking soft barrel 600. Since the bottle opening of the bottle blank 700 is arranged from top to bottom, the first heating source 2211, the second heating source 2212, the third heating source 2213 and the fourth heating source 2214 are also arranged in sequence from top to bottom. The first heating heat source 2211 is disposed at a top position; the fourth heating heat source 2214 is arranged at the bottom position; the second heating heat source 2212 and the third heating heat source 2213 are disposed between the first heating heat source 2211 and the fourth heating heat source 2214. In this embodiment, the third heating heat sources 2213 are two sets of heating heat sources, which are equally spaced between the second heating heat sources 2212 and the fourth heating heat sources 2214.

During the heating of the bottle blank 700:

and/or, the heating power ratio of the fourth heating heat source 2214 is greater than or equal to the heating power ratio of the third heating heat source 2213.

In one embodiment, the heating zone a2 of the preheater 240 includes a first preheater tube 2411, a second preheater tube 2412, a third preheater tube 2413, and a fourth preheater tube 2414. The first preheating pipe 2411 is disposed corresponding to the shoulder area of the bottle blank 700. The second preheating pipe 2412 is disposed corresponding to the upper region of the preform body of the preform 700. The third preheating pipe 2413 is disposed corresponding to the middle-lower area of the body of the bottle blank 700.

During the pre-heating of the bottle blank 700:

such that the heating power ratio of the first preheat tube 2411 is less than the heating power ratio of the second preheat tube 2412 or the fourth preheat tube 2414;

in one embodiment, during the heating process and the preheating process:

so that the heating power ratio of the first preheating pipe 2411 of the heating zone a2 of the preheating device 240 is smaller than the heating power ratio of the first heating heat source 2211 of the heating zone a1 of the heating device 220;

and/or, the heating power ratio of the fourth heat preservation pipe 2422 of the heat preservation area B2 of the preheating device 240 is the same as or similar to the heating power ratio of the second heat preservation pipe 2222 of the heat preservation area B1 of the heating device 220.

In one embodiment, during the heat treatment, air is supplied to the bottle blanks 700 by an air supply device 250. The air supply device 250 is disposed on the opposite side of the bottle blank 700 from the heating device 220. The air outlet of the air supply device 250 is arranged facing the bottle blank 700.

During the heating process of the bottle blank 700, the heating source 121 of the heating area a1 of the heating device 220 operates to heat the bottle blank 700. The heating power ratio of the first heat preservation pipe 2221 in the heat preservation area B1 of the heating device 220 is smaller than that of the second heat preservation pipe 2222, so as to preserve the heat of the bottom and the body of the bottle blank 700.

Referring to fig. 13, in one embodiment, the filling and capping device 300 includes a bottle holding device 310, a filling device 320, and a capping device 330. The bottle holding device 310 is disposed between the filling device 320 and the capping device 330. The tote apparatus 310 is used to transfer the soft drum 600 from the filling apparatus 320 to the capping apparatus 330 after the filling is completed. Wherein, the filling device 320 is used for quantitatively filling fresh mineral water into the soft barrel 600; the capping device 330 is used to cap the filled soft tub 600. In this embodiment, the filling device 320 includes a bung clamp fixed to a bung of the soft barrel, a soft barrel protection plate disposed at one side of the soft barrel for protecting the soft barrel, a tray disposed at a bottom of the soft barrel for protecting the bottom of the soft barrel, and a filling head disposed above the bung clamp for quantitatively filling fresh mineral water into the soft barrel;

since the soft barrel 600 is a negative pressure fresh-locking soft barrel, the problem of barrel body compression is to be considered in the design, and the barrel body of the soft barrel 600 is generally soft and convenient to compress. However, since the body of the soft tub 600 is soft, when the soft tub 600 is not closed after being filled with fresh mineral water, the body of the soft tub 600 is easily deformed due to the gravity of water, so that the soft tub 600 filled with fresh mineral water is not easily transferred from the filling apparatus 320 to the closing apparatus 330. Therefore, the bottle supporting device 310 provided by the embodiment of the present invention is to solve the above-mentioned problems.

Referring to fig. 14-17, in one embodiment, the bottle holding device 310 includes a bottle opening fixture 311 and a bottle holding mechanism 312. The bottle mouth fixing device 311 is used for taking out the soft barrel 600 filled with fresh mineral water from the filling equipment 320. The bottle supporting mechanism 312 is used for lifting the height of the soft barrel 600 when the soft barrel 600 is rapidly moved to the capping device 330 so as to support the bottom of the soft barrel 600, so that the soft barrel 600 is not easily deformed when being conveyed to the capping device 330.

Specifically, bottleneck fixing device 311 is including the bottle star gear 3111 of setting of rotating and with bottle star gear 3111 coaxial pivoted bottleneck star gear 3112. The bottle opening star wheel 3112 is fixed at a mouth of the soft barrel 600 and is used for taking out the soft barrel 600 from the filling device 320. In this embodiment, the bottleneck fixture 311 further includes a shaft 3113. Bottle poking star wheel 3111 is fixed on pivot 3113. The pivot 3113 can drive bottle star gear 3111 is rotatory.

The bottle supporting mechanism 312 is disposed at the bottom of the bottle opening star wheel 3112 and close to the cover closing device 330. When the soft barrel 600 moves above the bottle holding mechanism 312, the bottle holding mechanism 312 moves from the first position to the second position to hold the bottom of the soft barrel 600. When the soft barrel 600 is removed from above the pin-holding mechanism 312, the pin-holding mechanism 312 moves from the second position to the first position to return to the original position. At this time, the bottle holding mechanism 312 waits for the next bottle holding operation of the soft barrel 600. In this embodiment, the height of the pin setter 312 in the second position is greater than the height of the pin setter 312 in the first position. Specifically, when the bottle-opening star wheel 3111 conveys the filled soft barrel 600, the bottle-opening star wheel 3112 is fixed on the opening of the soft barrel 600. At this time, the soft barrel 600 may have its bottom stretched downward and its body deformed due to the gravity of water. At this time, since the bottle supporting mechanism 312 is disposed at a lower height in the first position, even if the soft tub 600 is deformed by the gravity of water, the deformed soft tub 600 can be smoothly moved to the upper side of the bottle supporting mechanism 312. When it is detected that the soft barrel 600 moves above the bottle holding mechanism 312, the bottle holding mechanism 312 is lifted and moves from the first position to the second position. Because the bottle supporting mechanism 312 is higher in the second position, it can be effectively supported at the bottom of the soft barrel 600, thereby preventing the deformation of the soft barrel 600. Even if the soft tub 600 is deformed, the bottle holding mechanism 312 can restore the soft tub 600 when it is held at the bottom of the soft tub 600. Since the bottle holding mechanism 312 is disposed close to the capping device 330, when the bottom of the soft barrel 600 is lifted, it can be effectively transferred to the capping device 330 for subsequent capping operation. At this time, after the sealing of the soft barrel 600 is completed, the size and the liquid level of the soft barrel are uniform, so that the integrity of the soft barrel 600 and the production efficiency of the filling equipment can be effectively maintained.

In one embodiment, the bottle holding mechanism 312 includes a first support plate 3121, a second support plate 3122, and a third support plate 3123. The first support plate 3121, the second support plate 3122, and the third support plate 3123 are disposed side by side and may reciprocate between a first position and a second position, respectively. In this embodiment, the first support plate 3121, the second support plate 3122, and the third support plate 3123 are respectively fan-shaped, and a center of a circle of the fan-shaped formed by the first support plate 3121, the second support plate 3122, and the third support plate 3123 is located on a rotation axis of the bottle-poking star wheel 3111. In one aspect, the bottle supporting mechanism 312 is configured to include first to third support plates 3121 and 3123, and the first to third support plates 3121 and 3123 can reciprocate between the first position and the second position, respectively. During the process of moving the soft tub 600 from the filling apparatus 320 to the capping apparatus 330, the first support plate 3121, the second support plate 3122, and the third support plate 3123 may sequentially ascend, thereby supporting the bottom of the soft tub 600. When the soft tub 600 is about to move to the capping device 330, the first pallet 3121, the second pallet 3122, and the third pallet 3123 may also be lowered in sequence to wait for the next cycle to arrive. It can be seen that, since the bottle holding mechanism 312 includes the first support plate 3121, the second support plate 3122 and the third support plate 3123, and the first to third support plates 3121 and 3123 can move respectively, the movement of the bottle holding mechanism 312 is more flexibly configured.

In one embodiment, a width of any one of the first support plate 3121, the second support plate 3122, and the third support plate 3123 is smaller than a bottom diameter of the soft tub 600. The width of any two adjacent support plates among the first support plate 3121, the second support plate 3122, and the third support plate 3123 is greater than the bottom diameter of the soft tub 600. On one hand, the width of any one of the first support plate 3121, the second support plate 3122 and the third support plate 3123 is set to be smaller than the barrel bottom diameter of the soft barrel 600, the movement design of the first to third support plates 3121 and 3123 is more flexible, and the adjustment is more convenient. On the other hand, the width of any two adjacent support plates among the first support plate 3121, the second support plate 3122, and the third support plate 3123 is set to be larger than the bucket bottom diameter of the soft bucket 600, and in the movement process of the soft bucket 600, the bucket bottom of the soft bucket 600 can be completely supported only by using any two adjacent support plates.

According to the requirement, rollers are arranged on the surface of the soft supporting barrel 600 for supporting one or more of the first supporting plate 3121, the second supporting plate 3122 and the third supporting plate 3123. The extension line of the rotation axis one end of gyro wheel passes set up of the axis of rotation of dialling bottle star gear 3111. In this embodiment, the surfaces of the supporting soft barrel 600 of the first to third supporting plates 121 and 123 are all provided with rollers. Specifically, the first support plate 3121 includes a first frame 31211 and a plurality of first rotation shafts 31212 provided in the first frame 31211. The plurality of first rotating shafts 31212 are radially distributed, and an extension line of one end of one or more first rotating shafts 31212 passes through the rotating shaft of the bottle poking star wheel 3111. Each of the first rotation shafts 31212 is penetrated with a plurality of first rollers 31213. When the soft tub 600 moves above the first support plate 3121, the first support plate 3121 is raised from the first position to the second position, so that the plurality of first rollers 31213 are brought into contact with the bottom surface of the soft tub 600. At this time, the first roller 31213 may be provided to reduce friction between the soft tub 600 and the surface of the first support plate 3121, so that the bottom of the soft tub 600 moves more smoothly on the surface of the first support plate 3121. In addition, due to the driving of the bottle-shifting star wheel 3111, the soft barrel 600 rotates around the rotation axis of the bottle-shifting star wheel 3111. At this time, an extension line of one end of the first rotating shaft 31212 of the first roller 31213 is disposed to pass through the rotating shaft of the bottle poking star wheel 3111, and the rolling direction of the first roller 31213 is the same as the moving direction of the soft tub 600, so that the friction force of the soft tub 600 when moving on the surface of the first support plate 3121 is further reduced. It is understood that, in the present embodiment, the second support plate 3122 may include a second frame 31221, a second rotation shaft 31222, and a second roller 31223; the third support plate 3123 may include a third frame 31231, a third rotation shaft 31232, and a third roller 31233. Specifically, the second support plate 3122 and the third support plate 3123 have a similar structure to the first support plate 3121, and thus, a detailed description thereof is omitted.

In one embodiment, the bottom of the capping device 330 is provided with a conveyor 340. The distance between the conveyor belt 340 and the bottle opening star wheel 3112 is equal to a second preset distance. In this embodiment, the value range of the second preset distance is as follows: is more than or equal to the distance between the opening support ring and the bottom of the soft barrel 600 when the soft barrel 600 is not filled with fresh mineral water; is less than or equal to the distance between the bottom of the soft barrel 600 and the supporting ring of the opening of the barrel after the barrel body of the soft barrel 600 deforms under the gravity of water after the soft barrel 600 is quantitatively filled with fresh mineral water. It can be understood that the value range of the second preset distance can be adjusted according to actual needs, as long as the value range is greater than or equal to the distance between the opening support ring and the bottom of the soft barrel 600 when the soft barrel 600 is not filled with fresh mineral water; and the distance between the bottom of the soft barrel 600 and the opening support ring is less than or equal to the distance between the barrel body of the soft barrel 600 and the opening support ring after the barrel body of the soft barrel 600 deforms under the gravity of water after the soft barrel 600 is quantitatively filled with fresh mineral water. The purpose of providing the conveyor belt 340 at the bottom of the capping device 330 is to: the conveyor 340 may transfer the covered soft tub 600 to a next process or apparatus. On the other hand, if the filled soft barrel 600 is not placed on the conveyor 340 for sealing, but the soft barrel 600 is only sealed by the fixing action of the bottle opening star wheel 3112, the barrel body of the soft barrel 600 may deform, and the deformation of each soft barrel 600 is not consistent, so that the shape of the soft barrel 600 after sealing is different, and the consistency of the produced product is poor. In this embodiment, the distance between the transmission belt 340 and the bottle opening star wheel 3112 is a second preset distance. That is, when the soft barrel 600 is disposed on the conveyor 340, due to the fixing function of the bottle opening star wheel 3112 and the supporting function of the conveyor 340, the barrel body and the barrel bottom of the soft barrel 600 are not substantially deformed during the capping process, so that the consistency of the size and the liquid level of the produced product is good.

When the bottle holding mechanism 312 moves to the second position, the height of the bottle holding mechanism 312 is aligned with the height of the conveyor belt 340. At this point, the soft barrel 600 may be effectively transferred from the carafe mechanism 312 to the capping device 330. If necessary, the height of the bottle supporting mechanism 312 may be slightly higher than the height of the conveying belt 340 when the bottle supporting mechanism 312 moves to the second position, so that the soft barrel 600 can be effectively transferred from the bottle supporting mechanism 312 to the capping device 330.

It will be appreciated that when the bottle holding mechanism 312 is moved to the first position, the distance between the upper surface of the bottle holding mechanism 312 and the finish star 3112 is greater than or equal to a first predetermined distance. In this embodiment, the first predetermined distance is a distance between the bottom of the soft barrel 600 and the opening support ring after the barrel body of the soft barrel 600 deforms under the gravity of water after the soft barrel 600 is filled with fresh mineral water. Because the distance between the upper surface of the bottle supporting mechanism 312 and the bottle opening star wheel 3112 is greater than or equal to the first preset distance, even if the soft barrel 600 deforms due to the gravity action of water, the deformed soft barrel 600 still cannot collide with the bottle supporting mechanism 312 in the moving process, so that the barrel of the soft barrel 600 is damaged.

In one embodiment, in order to achieve the reciprocating motion of the first support plate 3121, the second support plate 3122, and the third support plate 3123 at the first position and the second position, respectively, the bottle holding mechanism 312 further includes a first cylinder 3124, a second cylinder 3125, and a third cylinder 3126. The first cylinder 3124 is used for driving the first supporting plate 3121 to reciprocate between a first position and a second position. The second cylinder 3125 is configured to drive the second support plate 3122 to reciprocate between a first position and a second position. The third cylinder 3126 is configured to drive the third support plate 3123 to reciprocate between a first position and a second position. By arranging the first cylinder 3124, the second cylinder 3125 and the third cylinder 3126, the first to third cylinders 3124 and 3126 can respectively drive the first to third support plates 3121 and 3123 to move up and down, so that the control manner of the bottle supporting mechanism 312 is more flexible.

In one embodiment, in order to accurately detect the moving position of the soft tub 600 to determine whether the soft tub 600 moves above the first support plate 3121, the second support plate 3122, or the third support plate 3123, the bottle supporting mechanism 312 further includes a first position sensor 3127, a second position sensor 3128, and a third position sensor 3129. The first position sensor 3127 is used to detect whether the soft tub 600 moves above the first support plate 3121. The second position sensor 3128 is used to detect whether the soft tub 600 moves above the second support plate 3122. The third position sensor 3129 is used to detect whether the soft tub 600 moves above the third support plate 3123. In this embodiment, the first position sensor 3127 is disposed on the first support plate 3121 at a central region of the first support plate 3121. The first position sensor 3127 may be an infrared ray transmitting and/or receiving device, as needed. When the first position sensor 3127 is an infrared ray receiving device, an infrared ray emitting device may be disposed at an upper area of the first support plate 3121. When the soft barrel 600 does not run above the first support plate 3121, there is no obstacle between the infrared ray emitting device and the infrared ray receiving device, and the infrared ray emitted from the infrared ray emitting device can be received by the first position sensor 3127. When the soft tub 600 moves above the first support plate 3121, the first position sensor 3127 cannot receive the infrared rays emitted from the infrared ray emitting device due to the blocking effect of the soft tub 600. At this time, the first position sensor 3127 transmits a signal corresponding to the entrance of the soft tub 600 to the control mechanism, and the control mechanism controls the first supporting plate 3121 to ascend from the first position to the second position to support the bottom of the soft tub 600. When the soft tub 600 leaves above the first support plate 3121, the first position sensor 3127 receives the infrared rays emitted from the infrared ray emitting device again. At this time, the first position sensor 3127 transmits a signal that the corresponding soft tub 600 is separated to the control mechanism, and the control mechanism controls the first support plate 3121 to return from the second position to the first position. In this embodiment, the second position sensor 3128 is disposed on the second support plate 3122 and is located at a central region of the second support plate 3122; the third position sensor 3129 is disposed on the third support plate 3123 at a central region of the third support plate 3123. The second position sensor 3128 and the third position sensor 3129 may also be infrared ray transmitting and/or receiving devices. The second position sensor 3128 and the third position sensor 3129 operate in a similar manner to the first position sensor 3127, and are not described in detail herein.

According to the requirement, in the bottle holding mechanism 312, the distance between any two adjacent position sensors is smaller than the diameter of the bottom of the soft barrel 600, so that during the movement of the soft barrel 600 above the bottle holding mechanism 312, at least one of the first support plate 3121, the second support plate 3122 or the third support plate 3123 supports on the bottom of the soft barrel 600. In this embodiment, the first sensor 3127, the second sensor 3128, and the third sensor 3129 are sequentially arranged at intervals along the moving direction of the soft tub 600, and at this time, the distance between the first sensor 3127 and the second sensor 3128 is set to be smaller than the diameter of the bottom of the soft tub 600, or the distance between the second sensor 3128 and the third sensor 3129 is set to be smaller than the diameter of the bottom of the soft tub 600, so that it can be ensured that at least one of the first support plate 3121, the second support plate 3122, or the third support plate 3123 supports the bottom of the soft tub 600 during the movement of the soft tub 600 over the bottle supporting mechanism 312.

A fourth position sensor 342 may also be disposed on the conveyor belt 340 as needed. The fourth position sensor 342 is used for detecting the position of the soft barrel 600 on the conveyor 340.

In addition, since the first support plate 3121, the second support plate 3122, or the third support plate 3123 needs a certain time to move from the first position to the second position, in order to make the support plate support the bottom of the soft barrel 600 well, the speed of the upward movement of the support plate should match the rotation speed of the bottle-poking star wheel 3111. Specifically, the moving speed of the first palette 3121, the second palette 3122, or the third palette 3123 is V1, and the linear speed of the movement of the soft tub 600 at the central axis is V2. When the rim of the soft tub 600 moves just above the first sensor 3127, the first sensor 3127 detects the presence of the soft tub 600, and then the first support plate 3121 starts to ascend from the first position to the second position. At this time, if the first supporting plate 3121 moves to the second position, the moving distance of the soft barrel 600 is within the range of 1/3-2/3 of the diameter D1 of the soft barrel 600, and the supporting effect of the first supporting plate 3121 on the bottom of the soft barrel 600 is definitely better. At this time, i.e., the relationship between the moving speed V1 of the first palette 3121 and the linear speed V2 of the soft tub 600 moving at the central axis is:

(1/3)D1≤(H1/V1)*V2≤(2/3)D1。

in one embodiment, the pin setter 312 further includes a controller 313. The controller 313 is connected to the first cylinder 3124, the second cylinder 3125, the third cylinder 3126, the first position sensor 3127, the second position sensor 3128, and the third position sensor 3129, respectively. When the first position sensor 3127 detects that the soft tub 600 moves above the first supporting plate 3121, the controller 313 controls the first cylinder 3124 to move the first supporting plate 3121 from the first position to the second position to support the soft tub 600. When the second position sensor 3128 detects that the soft tub 600 moves above the second supporting plate 3122, the controller 313 controls the second cylinder 3125 to move the second supporting plate 3122 from the first position to the second position to support the soft tub 600. When the third position sensor 3129 detects that the soft tub 600 moves above the third supporting plate 3123, the controller 313 controls the third cylinder 3126 to move the third supporting plate 3123 from the first position to the second position to support the soft tub 600.

In one embodiment, a guard 314 is further disposed on the outside of the bottle holding device 310. The shield 314 surrounds the transport path of the soft tub 600 from the filling device 320 to the capping device 330.

In one embodiment, the bottom of the bottle holding device 310 is further provided with a carrying platform 315 for carrying the bottle mouth fixing device 311, the bottle holding mechanism 312, the guard plate 314, and the like. According to the requirement, a driving motor 341 is disposed at the bottom side of the carrying platform 315 for driving the bottle mouth fixing device 311 to rotate.

It should be understood that, in the bottle supporting device 310, the bottle mouth fixing device 311 is not limited to driving the soft barrel 600 to perform a rotational movement, but may also drive the soft barrel 600 to perform a linear or curved movement, as long as it can be fixed at the mouth of the soft barrel 600 and drive the soft barrel 600 to move.

One embodiment of the present invention further provides a soft barrel fresh mineral water filling and capping device 300, which comprises:

a filling device 320 for filling the soft tub 600 with fresh mineral water;

a capping device 330 for capping the filled soft tub 600; and

the bottle supporting device 310 according to any of the above embodiments is disposed between the filling device 320 and the capping device 330. The tote apparatus 310 is used to transfer filled soft buckets 600 from the filling apparatus 320 to the capping apparatus 330.

Referring to fig. 18 and 19 together, the operation of the soft barrel fresh mineral water filling and capping device is as follows:

the soft tub 600 is transferred to the filling apparatus 320 for filling of fresh mineral water. The filling apparatus 320 is a rotary filler, as desired. In this embodiment, the filling apparatus 320 includes a bung clamp 321, a soft drum guard 322, a tray 323, and a filling head 324. The bung hole anchor 321 is fixed at the bung hole of the soft drum 600. The soft barrel guard plate 322 is arranged on one side of the soft barrel 600 and used for protecting the soft barrel 600. The tray 323 is disposed at the bottom of the soft tub 600 to protect the bottom of the soft tub 600. The filling head 324 is disposed above the bung hole clamp 321 for quantitatively filling the soft barrel 600 with fresh mineral water. After the soft tub 600 is quantitatively filled with fresh mineral water, the soft tub 600 quantitatively filled with fresh mineral water is taken out of the tub opening jig 321 of the filling apparatus 320 by the bottle opening star wheel 3112 of the bottle opening fixing device 311. Specifically, bottleneck fixing device 311 is including the bottle star gear 3111 of setting of rotating and with bottle star gear 3111 coaxial pivoted bottleneck star gear 3112. When the soft drum 600 is removed from the filling device 320, the mouth star wheel 3112 is engaged with the mouth of the soft drum 600, so that the soft drum 600 is removed from the mouth clamp 321 of the filling device 320. In this embodiment, the filling head 324 is disposed above the bung clamp 321 and rotates synchronously with the bung clamp 321. When the bung hole of the soft barrel 600 is clamped on the bung hole clamp 321, the filling head 324 starts to fill the soft barrel 600 with fresh mineral water until the fresh mineral water in the soft barrel 600 reaches a preset water amount, thereby realizing uninterrupted filling and quantitative filling. In addition, because the soft barrel 600 is provided with the soft barrel guard plate 322 at the barrel body, the soft barrel guard plate 322 can also play a certain protection role for the soft barrel 600. Meanwhile, a tray 323 is disposed at a bottom position of the bung clamp 321. The tray 323 also rotates in synchronization with the bung fixture 321 to prevent the bottom of the soft drum 600 from excessively sinking during filling of the soft drum 600.

The bottle-pulling star wheel 3111 is always rotating to transfer the soft tub 600 filled with fresh mineral water in a fixed quantity to the capping device 330 on the opposite side to the filling device 320.

When the soft barrel 600 moves above the first support plate 3121, the first sensor 3127 does not receive the infrared rays emitted from the infrared ray emitting device due to the shielding of the soft barrel 600. At this time, the first sensor 3127 transmits a corresponding detection result to the controller 313. The controller 313 controls the first cylinder 3124 to lift the first support plate 3121 from the first position to the second position to support the soft tub 600 filled with a fixed amount of fresh spring water. At this time, since the first wheel 8213 is disposed on the surface of the first support plate 3121 contacting the soft tub 600, the soft tub 600 can be smoothly moved on the surface of the first support plate 3121.

When the soft barrel 600 moves above the second support plate 3122, the second sensor 3128 does not receive the infrared rays emitted from the infrared ray emitting device due to the shielding of the soft barrel 600. At this time, the second sensor 3128 transmits a corresponding detection result to the controller 313. The controller 313 controls the second cylinder 3125 to lift the second support plate 3122 from the first position to the second position to support the soft tub 600 filled with fresh spring water in a fixed amount. In addition, since the contact surface of the second support plate 3122 with the soft tub 600 is also provided with the roller, the soft tub 600 can be smoothly moved on the surface of the second support plate 3122. In addition, since the diameter of the bottom of the soft tub 600 is larger than the distance between the first sensor 3127 and the second sensor 3128, the first support plate 3121 and the second support plate 3122 are supported on the bottom of the soft tub 600.

When the soft tub 600 moves to be away from the upper side of the first support plate 3121, the first sensor 3127 receives the infrared rays emitted from the infrared ray emitting device again. At this time, the first sensor 3127 transmits a detection result that the soft bucket 600 leaves to the controller 313. The controller 313 controls the first cylinder 3124 to return the first support plate 3121 from the second position to the first position.

When the soft barrel 600 moves above the third support plate 3123, the third sensor 3129 does not receive the infrared rays emitted from the infrared ray emitting device due to the shielding of the soft barrel 600. At this time, the third sensor 3129 transmits a corresponding detection result to the controller 313. The controller 313 controls the third cylinder 3126 to lift the third support plate 3123 from the first position to the second position to support the soft tub 600 filled with fresh spring water in a fixed amount. In addition, since the contact surface of the third support plate 3123 with the soft tub 600 is also provided with the roller, the soft tub 600 can be smoothly moved on the surface of the third support plate 3123. In addition, since the diameter of the bottom of the soft tub 600 is larger than the distance between the second sensor 3128 and the third sensor 3129, the second support plate 3122 and the third support plate 3123 are supported on the bottom of the soft tub 600.

When the soft tub 600 moves to be away from the upper side of the second support plate 3122, the second sensor 3128 receives the infrared rays emitted from the infrared ray emitting device again. At this time, the second sensor 3128 transmits a detection result that the soft bucket 600 leaves to the controller 313. The controller 313 controls the second cylinder 3125 to return the second support plate 3122 from the second position to the first position.

When the third support plate 3123 is moved to the second position, the third support plate 3123 is actually spliced with the conveyor belt 340 of the capping apparatus 330. At this time, the soft tub 600 filled with fresh spring water in a fixed amount can be conveniently moved to the capping apparatus 330 by the third support plate 3123.

When the soft tub 600 moves to be away from the upper side of the third support plate 3123, the third sensor 3129 receives the infrared rays emitted from the infrared ray emitting device again. At this time, the third sensor 3129 transmits a detection result that the soft bucket 600 leaves to the controller 313. The controller 313 controls the third cylinder 3126 to return the third support plate 3123 from the second position to the first position.

When the soft tub 600 is completely moved to the transfer belt 340 of the capping device 330, the capping device 330 may perform a capping operation on the soft tub 600 filled with fresh mineral water in a fixed amount. In this embodiment, the distance between the transmission belt 340 and the bottle opening star wheel 3112 is equal to a second preset distance. That is, when the soft barrel 600 is disposed on the conveyor 340, due to the fixing function of the bottle opening star wheel 3112 and the supporting function of the conveyor 340, the barrel body and the barrel bottom of the soft barrel 600 are not substantially deformed during the capping process, so that the consistency of the produced products is good. After the soft tub 600 filled with fresh spring water is closed, the soft tub 600 may be subjected to the next process.

It is understood that, in the present embodiment, the filling device 320 is provided separately from the bottle supporting device 310, and after the filling device 320 fills the soft tub 600 with fresh spring water, the filled soft tub 600 is transferred to the capping device 330 through the bottle supporting device 310. The filling device 320 and the bottle holding device 310 may be provided as a single unit, if desired. As shown in fig. 20, a filling head 316 may be disposed above the pin holder apparatus 310. The filling head 316 may be fixed above the bottle mouth fixing device 311 and move along with the movement of the bottle mouth fixing device 311, so that the filling head 316 and the bung of the soft barrel 600 are relatively fixed, thereby facilitating the filling of fresh mineral water. In one embodiment, the vial mouth fixture 311 includes a rotatably disposed bottle-shifting star wheel 3111 and a plurality of vial mouth star wheels 3112 that rotate coaxially with the bottle-shifting star wheel 3111. A filling head 316 is arranged above each finish star 3112, and the filling head 210 is fixed to the spindle 3113 of the finish holder 311 and can be moved together with the spindle 3113. At this time, while the bottle-pulling star wheel 3111 rotates, the filling head 316 can also rotate relatively, so that the soft barrel 600 is conveyed and the fresh mineral water is filled simultaneously.

The filling and capping device 300 further comprises a flushing device 350, as required. The soft barrel 600 prepared by the bottle blowing mechanism 230 is flushed by the flushing device 350 before entering the filling device 320, so that the cleanliness of the soft barrel 600 is ensured again.

The filling and capping device 300 further includes a cap feeder 360, as needed. The cap feeder 360 delivers the caps to the capping apparatus 330. The capping device 330 is used for buckling the bottle caps conveyed by the cap conveying machine 360 to the soft barrel 600 filled with fresh mineral water in a fixed amount.

It can be understood that, since the temperature of the fresh mineral water filled into the soft barrel 600 in the filling device 300 from the underground deep rock is relatively constant in the filling and capping device 300, the time from the taking of the fresh mineral water from the deep rock to the filling is extremely short, the temperature of the fresh mineral water in the soft barrel packaged in the filling device 300 is lower than the ambient temperature in summer, and the condensed water is formed on the outer surface of the soft barrel due to the difference between the internal temperature and the external temperature. Therefore, an air drying device is provided at the outlet of the soft barrel 600 of the filling and capping device 300, for performing air drying treatment on the soft barrel 600 coming out of the filling and capping device 300.

The bottle supporting device 310, the filling device 320, the capping device 330, the flushing device 350 and the cap feeder 360 are arranged in a sterile clean room as required. The air in the sterile clean room is subjected to multi-stage sterilization and filtration, and is kept at a constant temperature and humidity, so that the freshness of the water quality of the filled fresh mineral water is provided again.

In the present embodiment, the cleanliness class of the aseptic transfer passage is class 5 (ISO14644-1), as required. The cleanliness grade of the sterile filling area is 5 grades, the temperature is 20-26 ℃, and the relative humidity is 30-70%; the static pressure difference is more than or equal to 10Pa, and fresh filling of the soft barrel of fresh mineral water is carried out in the filling environment.

Referring to fig. 21, the embodiment of the present invention further provides a filling process of fresh mineral water in soft barrels. The filling process of the soft barrel of fresh mineral water comprises the bottle supporting equipment or the soft barrel of fresh mineral water filling and sealing device provided by any one of the embodiments. The filling process of the soft barrel fresh mineral water comprises the following steps:

step S301: filling the soft barrel 600 with fresh mineral water by a filling device 320; in this embodiment, the filling device 320 includes a bung clamp fixed to a bung of the soft barrel, a soft barrel protection plate disposed at one side of the soft barrel for protecting the soft barrel, a tray disposed at a bottom of the soft barrel for protecting the bottom of the soft barrel, and a filling head disposed above the bung clamp for quantitatively filling fresh mineral water into the soft barrel;

step S302: fixing the opening of the soft barrel 600 on the bottle opening fixing device 311;

step S303: moving the bottleneck fixing device 311 to move the soft barrel 600;

step S304: when the soft barrel 600 moves above the bottle holding mechanism 312, the bottle holding mechanism 312 moves from the first position to the second position to hold the bottom of the soft barrel 600;

step S305: when the soft barrel 600 leaves above the pin setter 312, the pin setter 312 returns from the second position to the first position.

Step S306: after step S104, the soft barrel 600 is conveyed to the capping apparatus 330 for capping operation.

In one embodiment, the bottle holding mechanism 312 includes a first support plate 3121, a second support plate 3122, and a third support plate 3123. The first support plate 3121, the second support plate 3122, and the third support plate 3123 are disposed side by side and may reciprocate between a first position and a second position, respectively. Step S104 specifically includes:

detecting whether the soft barrel 600 runs above the first supporting plate 3121, and if so, controlling the first supporting plate 3121 to move from a first position to a second position to support the bottom of the soft barrel 600;

detecting whether the soft barrel 600 runs above the second supporting plate 3122, if yes, controlling the second supporting plate 3122 to move from the first position to the second position to support the bottom of the soft barrel 600;

whether the soft barrel 600 runs above the third supporting plate 3123 is detected, and if so, the third supporting plate 3123 is controlled to move from the first position to the second position to support the bottom of the soft barrel 600.

Since the bottle holding mechanism 312 includes the first support plate 3121, the second support plate 3122 and the third support plate 3123, and the first to third support plates 121 and 123 can move respectively, the movement of the bottle holding mechanism 312 is more flexible.

In one embodiment, the bottle holding mechanism 312 further comprises:

a first position sensor 3127 for detecting whether the soft tub 600 moves above the first support plate 3121;

a second position sensor 3128 for detecting whether the soft tub 600 moves above the second support plate 3122; and

a third position sensor 3129 for detecting whether the soft tub 600 moves above the third support plate 3123.

By providing the first position sensor 3127, the second position sensor 3128, and the third position sensor 3129, the bottle holding mechanism 312 can precisely detect the moving position of the soft tub 600 to determine whether the soft tub 600 moves above the first support plate 3121, the second support plate 3122, or the third support plate 3123.

In one embodiment, a width of any one of the first support plate 3121, the second support plate 3122, and the third support plate 3123 is smaller than a bottom diameter of the soft tub 600. The width of any two adjacent support plates among the first support plate 3121, the second support plate 3122, and the third support plate 3123 is greater than the bottom diameter of the soft tub 600. On one hand, the width of any one of the first support plate 3121, the second support plate 3122 and the third support plate 3123 is set to be smaller than the barrel bottom diameter of the soft barrel 600, the movement design of the first to third support plates 121 and 123 is more flexible, and the adjustment is more convenient. On the other hand, the width of any two adjacent support plates among the first support plate 3121, the second support plate 3122, and the third support plate 3123 is set to be larger than the bucket bottom diameter of the soft bucket 600, and in the movement process of the soft bucket 600, the bucket bottom of the soft bucket 600 can be completely supported only by using any two adjacent support plates.

In one embodiment, a roller is disposed on the surface of the soft supporting barrel 600 supporting one or more of the first supporting plate 3121, the second supporting plate 3122, and the third supporting plate 3123, and an extension line of one end of a rotation axis of the roller is disposed through a rotation axis of the bottle poking star wheel 3111. The arrangement of the rollers can reduce the friction between the soft barrel 600 and the surfaces of the first to third supporting plates 121 and 123, so that the bottom of the soft barrel 600 moves more smoothly on the surfaces of the first to third supporting plates 121 and 123. In addition, due to the driving of the bottle-shifting star wheel 3111, the soft barrel 600 rotates around the rotation axis of the bottle-shifting star wheel 3111. At this time, an extension line of one end of the rotating shaft of the roller passes through the rotating shaft of the bottle poking star wheel 3111, and the rolling direction of the roller is the same as the moving direction of the soft barrel 600, so as to further reduce the friction force when the soft barrel 600 moves on the surfaces of the first to third supporting plates 121 and 123.

In one embodiment, in step S102, the filled soft barrel 600 is taken out of the filling equipment 320 through the mouth fixing device 311. Bottleneck fixing device 311 is including the bottle star gear 3111 that rotates the setting and with bottle star gear 3111 coaxial pivoted bottleneck star gear 3112 of dialling. The bottleneck star wheel 3112 is fixed at the bung hole department of soft bucket 600.

In step S103, the bottle-shifting star wheel 3111 is rotated to move the filled soft barrel 600 toward the capping device 330.

In one embodiment, the bottom of the capping device 330 is provided with a conveyor 340. The distance between the conveyor belt 340 and the bottle opening star wheel 3112 is equal to a second preset distance.

In one embodiment, when the pin setter 312 moves to the second position, the height of the pin setter 312 is flush with the height of the conveyor belt 340.

In one embodiment, when the bottle holding mechanism 312 moves to the first position, the distance between the upper surface of the bottle holding mechanism 312 and the bottle opening star wheel 3112 is greater than a first preset distance.

The purpose of providing the conveyor belt 340 at the bottom of the capping device 330 is to: the conveyor 340 may transfer the covered soft tub 600 to a next process or apparatus. In addition, the distance between the transmission belt 340 and the bottle opening star wheel 3112 is equal to a second preset distance. That is, when the soft barrel 600 is disposed on the conveyor 340, due to the fixing function of the bottle opening star wheel 3112 and the supporting function of the conveyor 340, the barrel body and the barrel bottom of the soft barrel 600 are not substantially deformed during the capping process, so that the consistency of the produced products is good.

In one embodiment, the first support plate 3121, the second support plate 3122, and the third support plate 3123 are respectively fan-shaped, and a center of a circle of the fan-shaped formed by the first support plate 3121, the second support plate 3122, and the third support plate 3123 is located on a rotation axis of the bottle poking star wheel 3111.

In the soft barrel fresh mineral water filling process provided in the above embodiment, by providing the bottle mouth fixing device 311 and the bottle supporting mechanism 312, the bottle mouth fixing device 311 and the bottle supporting mechanism 312 can effectively convey the filled soft barrel 600 from the filling apparatus 320 to the capping apparatus 330 without deforming the barrel body of the soft barrel 600. Specifically, bottleneck fixing device 311 is including the bottle star gear 3111 of setting of rotating and with bottle star gear 3111 coaxial pivoted bottleneck star gear 3112. The bottleneck star wheel 3112 is fixed at the bung hole department of soft bucket 600. That is, the soft tub 600 is mainly transferred by the rotation of the bottle-pulling star wheel 3111. On the other hand, since the bottle supporting mechanism 312 is disposed at the bottom of the bottle opening star wheel 3112 and is disposed close to the capping device 330, when the soft barrel 600 moves to above the bottle supporting mechanism 312, the bottle supporting mechanism 312 moves from the first position to the second position to support the soft barrel 600. When the soft barrel 600 is removed from above the pin-holding mechanism 312, the pin-holding mechanism 312 moves from the second position to the first position to return to the original position. It can be seen that, through the repeated movement of the bottle supporting mechanism 312 at the first position and the second position, the bottle supporting mechanism 312 can effectively support the bottom of the filled soft barrel 600, so that the filled soft barrel 600 is not deformed, and the soft barrel 600 can be conveniently transferred to the capping device 330.

Referring to fig. 22 to 23, the soft serve fresh spring water production system 100 includes a soft serve orientation adjustment system 800. The direction adjusting system 800 is arranged in front of the boxing apparatus 400, and is used for adjusting the direction of the soft barrel 600 to a preset direction, and then conveying the soft barrel to the boxing apparatus 400 for boxing treatment. The soft tub orientation adjustment system 800 includes a base 810, a first sidewall 820, and a second sidewall 830. In this embodiment, the first sidewall 820 is disposed on one side of the base 810; the second sidewall 830 is disposed at the other side of the base 810. The base 810 is disposed between the first sidewall 820 and the second sidewall 830.

A transmission belt 811 is disposed on the base 810. The conveyor 811 is used to convey the soft tub 600. In this embodiment, the direction of the arrow in the transmission belt 811 is the moving direction of the soft tub 600. The soft barrel 600 has a polygonal barrel body. In this embodiment, the soft bucket 600 includes a hexagonal bucket body structure. For the hexagonal tub structure, since the widths of the tub in various directions are not uniform, there is a problem in the arrangement of the conveyor belt 811 and the first and second sidewalls 820 and 830. If the distance between the first side wall 820 and the second side wall 830 is set to be larger, for example, larger than the maximum distance between the body sides of the soft tub 600 (i.e., the distance between two opposite corners of the hexagon in the present embodiment). Then, when the soft barrel 600 is transported on the transport belt 811, there are various postures, so that the boxing process of the subsequent boxing apparatus is not easy to align. If the distance between the first side wall 820 and the second side wall 830 is set to be smaller, for example, slightly larger than or equal to the minimum distance (in this embodiment, the distance between two opposite sides of the hexagon) of the barrel side surface of the soft barrel 600 passing through the central axis of the barrel. Then, only the correctly positioned soft barrel 600 can be transported to the packing equipment through the conveyor 811. If the soft barrel 600 is slightly out of position, it will be stuck at the entrance of the transmission belt 811, so that the transmission belt 811 cannot work normally. It can be seen that the arrangement of the base 810, the first sidewall 820 and the second sidewall 830 is particularly important. The barrel body of the soft barrel 600 may also be an octagonal structure or other polygonal structures, which may be determined according to actual needs.

In the soft tub direction adjusting system 800, a distance between the first side wall 820 and the second side wall 830 at an opening of the conveyor 811 is greater than a distance between the first side wall 820 and the second side wall 830 at any position in the middle of the conveyor 811.

In one embodiment, the soft bucket directional adjustment system 800 includes a first directional adjustment zone a and a second directional adjustment zone B. The first direction adjustment area a is disposed near an opening of the transfer belt 811. The second direction adjustment area B is disposed away from an opening of the transmission belt 811. On the first direction adjustment area a, the interval between the first sidewall 820 and the second sidewall 830 is gradually decreased in the transport direction along the transport belt 811. That is, in the moving direction of the conveyor 811, the first sidewall 820 and the second sidewall 830 together form a trapezoidal shape having a large inlet pitch and a small outlet pitch. In the first direction adjustment area a, the distance between the first side wall 820 and the second side wall 830 at the entrance is larger than the distance between two opposite corners of the soft barrel 600 passing through the central axis of the barrel body, so that the soft barrel 600 in any position can enter the conveying belt 811 through the entrance of the first side wall 820 and the second side wall 830. In the first direction adjustment area a, the distance between the first side wall 820 and the second side wall 830 at the outlet is slightly larger than or equal to the minimum distance between the two sides of the soft barrel 600 passing through the central axis of the barrel body, so that the soft barrel 600 entering the conveying belt 811 from the inlet in any direction is output from the outlet of the conveying belt 811 according to a preset direction.

Referring also to fig. 24, in one embodiment, the soft serve fresh mineral water production system 100 further includes a multi-channel buffer system 900. The multichannel buffer system 900 is disposed between the filling and capping device 300 and the boxing device 400. The multi-channel buffer system 900 includes a first connection segment 910, a second connection segment 920, a first buffer channel 930, a second buffer channel 940, a first transit device 950, and a second transit device 960.

The first connecting section 910 is connected to the filling and capping device 300.

The second connection section 920 is connected to the boxing apparatus 400.

A first buffer passage 930 and a second buffer passage 940 are arranged in parallel between the first connection section 910 and the second connection section 920.

A first switching device 950 is disposed on the first connection section 910 and selectively connected with the first buffer passage 930 or the second buffer passage 940.

A second transit device 960 is disposed on the second connection segment 920 and selectively connected with the first buffer channel 930 or the second buffer channel 940.

In the actual production process of the soft serve fresh spring water production system 100, since the filling and capping device 300 continuously produces the soft serve fresh spring water, the soft serve 600, which is filled with fresh spring water, is continuously transferred to the first coupling stage 910, transferred to the second coupling stage 920 through the first buffer passage 930 or the second buffer passage 940, and then transferred to the packing device 400. However, if the packing device 400 is not disposed of in a timely manner, the soft tub 600 filled with fresh spring water may be stacked at the first connection stage 910. Therefore, by providing the first buffer passage 930 and the second buffer passage 940, when the soft tub 600 is stacked at the first buffer passage 930, the first transfer apparatus 950 and the second transfer apparatus 960 may be connected to the second buffer passage 940, thereby preventing the stacking of the soft tub 600. That is, the arrangement may prevent the soft tub 600 from being piled up by providing the first buffer passage 930 and the second buffer passage 940, and the first transfer device 950 and the second transfer device 960 selectively connected to the first buffer passage 930 or the second buffer passage 940. According to the requirement, the multi-channel buffer system 900 may further be provided with a third buffer channel 970, and the third buffer channel 970, the first buffer channel 930 and the second buffer channel 940 are arranged in parallel to further avoid the accumulation of the soft barrel 600.

In one embodiment, the soft serve fresh mineral water production system 100 further comprises a fan filter module. The fan filtering module is arranged in the sterile conveying channel 500 between the bottle blowing device 100 and the filling and capping device 300 and is used for keeping the sterile and clean positive pressure environment of the soft barrel conveying channel.

In one embodiment, the soft serve fresh mineral water production system 100 further includes an ion dusting device. The ion dust removal device is arranged between the blank feeding mechanism and the bottle blowing device 100 and is used for removing dust from the bottle blanks 700.

According to the requirement, a labeling device, a shrinking device and a coding device can be arranged between the second connecting section 920 of the multi-channel buffer system 900 and the direction adjusting system 800. The label sleeving device is used for sleeving a label on the soft barrel 600. The shrinking apparatus serves to shrink the label, thereby fixing the label to the soft tub 600. The coding device is used for coding corresponding production information on the soft barrel 600 or the label.

In the area of the boxing apparatus 400, the soft barrel fresh mineral water production system 100 further comprises a box supplying apparatus, a box sealing apparatus, a coding apparatus, a handle attaching apparatus 10 and a stacking apparatus. In the packing process of the packing device 400, the packing supply apparatus first supplies the packing boxes into the packing apparatus 400, and then the packing apparatus 400 puts the packed soft bucket of fresh mineral water into the packing boxes. The package is then conveyed to a box sealing apparatus 60 for a box sealing process. And the packing box after box sealing is conveyed to the handle pasting equipment again for carrying out handle pasting treatment. And finally, conveying the packaging box with the attached handle to stacking equipment for stacking.
