Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Figure 1 is a schematic diagram of a cleaning assembly 10 in one embodiment. The cleaning assembly 10 includes a head unit 100 and a blowing unit 200. The brush head unit 100 is used to roll brush the object to be cleaned to remove dust and the like from the object to be cleaned. Dirt such as dust may adhere to the brush head unit 100 after a long time use. Contaminants attached to the brush head unit 100 are removed by the air blowing unit 200. The object to be cleaned may be, for example, the conveying assembly 500, or may be other objects to be cleaned.

For example, the brushhead unit 100 includes a brush 110 and a first drive element 120. The first driving member 120 is connected to the brush 110 to drive the brush 110 to rotate about the rotation axis of the brush 110 itself. The first driving member 120 may be a motor, and a rotation shaft of the motor is connected to the brush 110 to rotate the brush 110. In order to improve the cleaning efficiency of the brush 110, the brush 110 may have a long bar shape. For example, when the brush 110 is used to clean a conveyor assembly 500 such as a conveyor belt, the length of the brush 110 along the extension direction of the rotation axis should be not less than the width of the conveyor belt, so that the brush 110 can cover the width direction of the conveyor belt, and when the conveyor belt is cleaned, the brush 110 only needs to rotate around the rotation axis thereof, but does not need to move along the extension direction of the rotation axis, so that the brush head unit 100 has high cleaning efficiency.

When the sole is processed, the sole is conveyed through the conveying belt, and glue or liquid medicine is sprayed on the sole on the conveying belt through the spray head. After a long time use, dust, glue residues and the like remain on the conveyor belt. The dust and glue residues on the conveyor belt can be removed by the brush 110. Because the glue has some tackiness, the glue removed from the belt tends to adhere back to the brush 110. When the brush 110 is contaminated, the belt may be secondarily contaminated while being cleaned by the brush 110.

For this, the brush 110 is blown by the blowing unit 200 to remove contaminants attached to the brush 110. For example, the air blowing unit 200 includes an air blowing pipe 210 and a second driving member 220, the second driving member 220 being connected to the air blowing pipe 210 to drive the air blowing pipe 210 to slidably move in a direction parallel to the axis of the brush 110, the air blowing pipe 210 being used to blow air toward the brush 110, thereby cleaning the brush 110.

The air blowing pipe 210 is usually connected to a high pressure air source, and the dirt such as glue residue can be easily peeled off from the brush 110 by the high speed air flow provided by the high pressure air source. Therefore, in order to improve the effect of removing contaminants having a certain viscosity such as glue, it is necessary to maintain a high flow rate of the air flow blown out from the blow pipe 210. Therefore, the diameter of the insufflation tube 210 is not typically made larger in order to reduce the pressure loss from the high pressure air source. After the high pressure air flow is discharged from the blowing pipe 210, the high pressure air flow is discharged in a cone shape, and the speed of the air flow is slower at the outermost end of the cone-shaped air flow. When the brush 110 is in a strip shape, if the position of the gas blowing pipe 210 is fixed and the gas outlet of the gas blowing pipe 210 blows gas toward the middle of the brush 110, the intensity of the gas flow passing through the two ends of the brush 110 is not strong than the intensity of the gas flow passing through the middle of the brush 110, and thus the cleaning effect on the two ends of the brush 110 is not good. The blowpipe 210 is slidably moved in a direction substantially parallel to the axis of the brush 110 by the second driving member 220 so that each position of the brush 110 in its axial direction can be covered with a strong air current. Therefore, the cleaning effect of the whole brush 110 is better, and the cleaning capability of each position of the brush 110 along the self-axial direction is uniform and stable.

It should be noted that the blowpipe 210 moves substantially in a direction parallel to the axis of the brush 110, and it is understood that the moving direction of the blowpipe 210 may be the same as the axis direction of the brush 110; it can also be understood that the moving direction of the blowpipe 210 and the axial direction of the brush 110 form an acute angle, so that the maximum blowing intensity of the blowpipe 210 to each portion of the brush 110 in the axial direction is substantially the same. For example, the direction of movement of the insufflation tube 210 may be at an angle of 60 to the axial direction of the brush 110, or less.

In the above embodiment, the second driving element 220 may be a cylinder. The second driving element 220 may also be a screw rod driven by a motor, a threaded sleeve is connected to the screw rod through a thread, and the gas blowing pipe 210 is connected to the threaded sleeve.

For example, the cleaning assembly 10 may include a guide unit 10A, the guide unit 10A may include a guide rod 10A1 and a guide block 10A2, and the guide rod 10A1 may extend in a direction substantially the same as the axial direction of the brush 110 or may form an acute angle with the axial direction of the brush 110. The guide block 10a2 is slidably connected to the guide bar 10a 1. For example, if the guide bar 10a1 has a circular cross section, the guide bar 10a1 has at least two guide bars 10a1 arranged in parallel, and the guide block 10a2 is slidably connected to at least two guide bars 10a 1. For example, if the guide bar 10a1 has a square cross section, the guide block 10a2 may have a square cross section of the hole for engaging with the guide bar 10a1, and one guide bar 10a1 may be provided.

In one embodiment, the cleaning assembly 10 includes a water spray unit including a spray tube member and a dirt cup 310. The spray pipe member sprays water toward the brush 110. The dirt receiving cover 310 is provided at the bottom of the brush 110 to receive water falling from the brush 110.

Fig. 2 is a schematic diagram of a filter unit 400 in the cleaning assembly 10 in one embodiment. In one embodiment, as shown in FIG. 2, the cleaning assembly 10 includes a filter unit 400. The filtering unit 400 is connected to the water spraying unit, water in the sewage receiving cover 310 is discharged into the filtering unit 400, the filtering unit 400 filters the sewage in the sewage receiving cover 310 to form clean water, and then the clean water is sprayed toward the brush 110 by the water spraying pipe member to form recycling of the water. For example, the filter unit 400 includes a filter tank 410 and a filter member 420 disposed within the filter tank 410, the filter member 420 dividing the filter tank 410 into a pre-filtration region 411 and a post-filtration region 412. The filtering tank 410 is provided with a water inlet 430 and a water outlet 440, the water inlet 430 is communicated with the front filtering area 411, and the water outlet 440 is connected with the rear filtering area 412. The water inlet 430 communicates with the dirt collection cover 310 to enable water within the dirt collection cover 310 to be discharged into the pre-filtering area 411. The drain port 440 communicates with the spout member so that filtered water can be discharged through the spout member. It will be appreciated that the spout member includes a tube and a water absorbing member such as a water pump connected to the tube in order to enable the spout member to absorb water from the filtered area 412. The filtering member 420 may be filter cotton, a filter net, filter paper, or the like.

Fig. 3 is a schematic diagram of a filter unit 400 in the cleaning assembly 10 in one embodiment. In the embodiment shown in fig. 2, the filter unit 400 is disposed outside the dirt collection cover 310, and in the embodiment shown in fig. 3, the filter unit 400 is disposed inside the dirt collection cover 310. For example, filter unit 400 includes a filter member 420 disposed inside of dirt cup 310, where filter member 420 divides dirt cup 310 into a pre-filtration region 411 and a post-filtration region 412. The dirt collecting cover 310 is provided with a water outlet 440 communicated with the filtered area 412, and the water outlet 440 is communicated with the water spraying pipe component.

Fig. 4 is a schematic structural view of an applicator in one embodiment. The spraying machine can be used for spraying glue or liquid medicine on the soles. The spray coater may also spray the solvent on other objects to be sprayed 800.

As shown in fig. 4, the applicator includes a delivery assembly 500, the delivery assembly 500 being used to deliver a shoe sole waiting for spray 800. The conveyor assembly 500 has an input end 510 and an output end 520, and the shoe sole waiting for the spray 800 is placed on the conveyor assembly 500 from the input end 510 and the conveyor assembly 500 transports the shoe sole to the output end 520. The conveyor assembly 500 may be a conveyor belt, a conveyor chain, or the like.

The applicator also includes a spray assembly 600 disposed beside the transfer assembly 500 and between the input end 510 and the output end 520. The spray assembly 600 is used to spray glue or the like to the shoe soles waiting to be sprayed 800 on the conveyor belt. The spray assembly 600 includes a robot 610 and a spray valve unit 620 driven to move by the robot 610. The robot 610 drives the spray valve unit 620 to move, thereby spraying glue to an area of the shoe sole where the glue is required to be sprayed.

For example, the transfer assembly 500 may be single-station or multi-station. The multiple stations can be double stations or three stations and the like. With the transfer assembly 500 in the simplex position, the shoe soles awaiting spray 800 may be placed in a single row on the transfer assembly 500. When the conveyor assembly 500 is double-station, the shoe soles waiting for spray 800 can be placed on the conveyor assembly 500 in two columns.

The conveyor assembly 500 transports the shoe sole waiting spray 800 in a conveying direction from the input end 510 to the output end 520, and the shoe sole waiting spray 800 is sprayed with glue or the like by the spray assembly 600 while passing through the working area of the spray assembly 600. The applicator also includes an image scanning assembly 700, the image scanning assembly 700 being located upstream of the spray assembly 600 along the direction of conveyance of the conveyor assembly 500. In operation, the shoe soles are transported in the transport direction through the working area of the image scanning assembly 700 and then through the working area of the spraying assembly 600. The shape of the shoe sole is scanned by image scanning assembly 700 while the shoe sole is in the work area of image scanning assembly 700 to determine the area on the shoe sole to be painted and determine the painting trajectory. The image scanning assembly 700 may include, among other things, a gantry 710 and a 3D camera 720 disposed on the gantry 710. The 3D camera 720 is used to scan the area to be painted of the object to be painted 800 and determine the painting trajectory. The spray assembly 600 receives signals indicating the area to be sprayed and the spray trajectory, and when the shoe sole moves to the working area of the spray assembly 600, the robot 610 drives the spray valve unit 620 to spray glue or other solvent to the spray area of the shoe sole according to the spray trajectory.

As shown in fig. 4, the conveyor assembly 500 is a dual station and can simultaneously convey two rows of material 800 to be sprayed in a conveying direction. The number of spray assemblies 600 is generally the same as the number of stations, i.e., the applicator of fig. 4 is provided with two spray assemblies 600, and the two spray assemblies 600 may be disposed on the same side of the conveyor assembly 500 or on both sides of the conveyor assembly 500. When the conveying assembly 500 moves the object 800 to be painted along the conveying direction, the object 800 to be painted first passes through the working area of the image scanning assembly 700 and then enters the working area of the painting assembly 600. The spray valve unit 620 is driven by the robot 610 to spray glue or other solvent to the spray area of the shoe sole according to the spray trajectory.

As shown in fig. 5, fig. 5 is a schematic structural view of a spray valve unit 620 in the coating machine in one embodiment. The spray valve unit 620 includes a mounting frame 621 and a spray valve body 622, the spray valve body 622 being mounted on the mounting frame 621, the mounting frame 621 being mounted at a moving end of the robot 610. The mounting rack 621 includes a fixed rack 6211 and a movable rack 6212, the movable rack 6212 is mounted on the fixed rack 6211 in an adjustable position, the fixed rack 6211 can be mounted on the movable end of the robot 610, and the spray valve body 622 can be mounted on the movable rack 6212. The fixed bracket 6211 can be provided with an adjustment slot 6211A, the adjustment slot 6211A can be an arc slot as shown in FIG. 5, and the movable bracket 6212 can be fastened to different positions of the adjustment slot 6211A by fasteners. In other embodiments, the adjustment slot 6211A can also be a straight slot. The nozzle valve main body 622 is further provided with a nozzle amount adjuster 623, and the amount of liquid discharged from the nozzle valve main body 622 can be adjusted by the nozzle amount adjuster 623.

Glue and the like can be sprayed on the object 800 to be sprayed through the spray valve body 622 in the spray valve unit 620, and due to the viscosity of the glue, after a period of operation, the glue can block the spray valve body 622, which causes the sprayed amount of the glue to be reduced, and further causes the amount of the glue on the sole to be insufficient. Alternatively, when the spray valve unit 620 needs to be changed from spraying glue to spraying liquid medicine, the glue remaining on the spray valve body 622 may contaminate the liquid medicine. Accordingly, in one embodiment, the sprayer further includes a spray valve cleaning unit 630 for cleaning the spray valve body 622 in the spray assembly 600.

As shown in fig. 6, fig. 6 is a schematic structural diagram of a spray valve cleaning unit 630 in the coating machine in one embodiment. The spray valve cleaning unit 630 includes a water reservoir 635 and a cleaning brush 636 disposed within the outlet tank. The spray valve unit 620 may be driven by the robot 610 in the spray assembly 600 to dip into the reservoir 635 and the spray valve unit 620 may be driven by the robot 610 to move within the reservoir 635 to brush the spray valve unit 620 with the cleaning brush 636. In order to enhance the cleaning effect of the cleaning brush 636 on the spray valve unit 620, the spray valve cleaning unit 630 further includes a fourth driving member 637 connected to the cleaning brush 636 to drive the cleaning brush 636 to rotate, and the fourth driving member 637 may be a motor.

The spray valve cleaning unit 630 further includes a return pipe 631, a drain pipe 633, and a third driving member 632. Return pipe 631 may be coupled to drain 440 in the embodiment shown in FIG. 2 or FIG. 3. The water outlet pipe 633 can be connected to the water inlet 430 in the embodiment shown in fig. 2, or directly connected to the pre-filtering area 411 in the embodiment shown in fig. 3. The sewage in the storage tank 635 is filtered and purified by the filter unit 400, the third driving element 632 is connected to the return pipe 631, and the filtered and purified water flows back to the storage tank 635 through the return pipe 631, and the third driving element 632 may be a water pump. Of course, in other embodiments, the drain pipe 633 may also discharge the wastewater directly to a wastewater basin, and the return pipe 631 may be connected to a clean water basin to provide clean water to the storage tank 635. The spray valve cleaning unit 630 further includes a blow-down valve 634 connected to the reservoir tank, and contaminants deposited on the bottom of the reservoir tank 635 can be discharged through the blow-down valve 634.

As shown in fig. 4, the conveying assembly 500 in the spraying machine conveys the objects 800 to be sprayed on the soles, and during the conveying process, the spraying assembly 600 sprays a solvent such as glue on the objects 800 to be sprayed, and the glue is easy to splash onto the conveying assembly 500 during the spraying process, so that the conveying assembly 500 is polluted. To this end, the applicator further includes a cleaning assembly 10 coupled to the transfer assembly 500 for cleaning contaminants on the transfer assembly 500. The cleaning assembly 10 may be the cleaning assembly 10 of any of the embodiments described above.

For example, as shown in fig. 1, the cleaning assembly 10 includes a dirt collection cover 310, a brush head unit 100 is disposed in the dirt collection cover 310, and the brush head unit 100 is connected with a first driving element 120 for driving the brush head unit 100 to rotate. The top of the dirt collecting cover 310 is provided with a dirt inlet 320, at least a part of the brush head unit 100 can extend out of the dirt inlet 320, and the brush head unit 100 can clean the conveying assembly 500. For example, when the conveying assembly 500 is a conveyor belt, the brush head unit 100 can contact the belt surface of the conveyor belt and the first driving element 120 drives the brush head unit 100 to rotate so as to clean the dirt attached to the belt surface of the conveyor belt, and the cleaned dirt enters the dirt receiving cover 310 through the dirt inlet 320. For example, cleaning assembly 10 may be disposed at output end 520 of conveyor assembly 500, and dirt on the belt face of conveyor assembly 500 may be swept by cleaning assembly 10 disposed at output end 520 before returning to input end 510.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
