It is understood that the following text is intended only to describe one or several particular embodiments of the application and does not strictly limit the scope of the claims which are specifically claimed herein, and that the examples and features of the examples in this application may be combined with one another without conflict.

As shown in fig. 3 to 15, the present application provides an apparatus for assembling a packing box, which aims to solve the technical problems that: the operation of traditional equipment packing carton relies on the manual work, and production efficiency is low, and the quality standard of product can not be unified and be controlled.

The basic implementation scheme provided by the embodiment of the application is as follows: the packaging box 100 comprises two hard box plates 110 arranged at intervals and a flexible box skin 120 wrapping the edge of the box plate 110, and comprises a molding mold core 300, a positioning mechanism 400 and a rolling mechanism, wherein the molding mold core 300 is provided with a molding part for molding the box skin 120, the molding part is provided with a molding surface, two sides of the molding mold core 300 are provided with accommodating parts 350 for accommodating the box plates 110, the accommodating parts 350 are positioned on two sides of the molding surface, when the molding surface and the accommodating parts 350 are in a working state, the plate side edges and the molding surface of the gluing position on the box plates 110 at the accommodating parts 350 are arranged in a forward and backward manner, the positioning mechanism 400 positions the glued box skin 120, and the rolling mechanism performs rolling adhesion on the gluing position of the edge of the box skin 120 and the gluing position of the box plates 110.

The basic principle of the embodiment of the application is as follows: positioning the box skin 120 by using the positioning mechanism 400, and gluing the box skin 120; then, the molding surface of the molding core 300 is attached to the box cover 120, and the accommodating part 350 and the molding surface of the molding core 300 are adjusted to be in a working state; then assembling the glued box plate 110 into the accommodating part 350 for positioning, so that the plate side edge and the molding surface at the glued position on the box plate 110 at the accommodating part 350 are arranged along the same direction; finally, the glued part of the edge of the box skin 120 and the glued part of the box plate 110 are rolled and bonded by a rolling mechanism along the molding surface, so that the wooden packing box 100 is assembled.

Taking the rectangular box plate 110 as an example, the outline of the molding surface is substantially consistent with the outline of the gluing part on the peripheral side of the box plate 110, the plate side of the gluing part on the box plate 110 comprises the bottom edge of the box plate 110 in the height direction and two side edges of the box plate 110 in the width direction, the gluing part on the edge of the box skin 120 refers to two side edges of the box skin 120 in the width direction, the two side edges are both glued, and the gluing range can meet the requirement that the box skin 120 and the box plate 110 are reliably bonded together after the box skin 120 is rolled along the molding surface.

According to the equipment for assembling the packing box, the box skin 120 is molded through the molding part on the molding mold core 300, the box plate 110 is accommodated in a working state through the accommodating parts 350 arranged on the two sides of the molding mold core 300, the plate side edge and the molding surface of the glue coating part on the box plate 110 are arranged along the same direction, the glued box skin 120 is positioned through the positioning mechanism 400, and the glue coating part on the edge part of the box skin 120 and the glue coating part on the box plate 110 are rolled and bonded through the rolling mechanism, so that the assembly of the packing box 100 is completed. The equipment is used for assembling the packing box 100, so that the workload of manual participation can be greatly reduced, the automation level of the assembling operation of the packing box 100 is improved, and the assembling efficiency of the packing box 100 is further improved; in addition, since the assembly operation of the packing box 100 is mostly performed by the apparatus, it is convenient to uniformly control the quality standard of the product.

Since the receiving portion 350 is in an operating state, the side edges of the plate and the molding surface where the glue is applied to the cartridge plate 110 at the receiving portion 350 are arranged along the same line. Therefore, in specific implementation, the preferred scheme of the embodiment of the present application is: referring to fig. 2 to 4, the cartridge panels 110 are vertically arranged in the accommodating portion 350, a limiting member 360 for moving the cartridge panels 110 in the width direction and moving the cartridge panels 110 upward is formed on the upper side of the accommodating portion 350, a moving-out opening 351 for moving the cartridge panels 110 downward out of the accommodating portion 350 is formed on the lower side of the accommodating portion 350, and the cartridge panels 110 are horizontally moved from the outside of the accommodating portion 350 into the accommodating portion 350 in the thickness direction. Due to the limiting effect of the limiting part 360, the box plate 110 at the accommodating part 350 cannot move in the plate width direction, so that the box plate 110 can be accurately positioned in the plate width direction, and the plate side edge and the molding surface at the gluing part of the box plate 110 at the accommodating part 350 are arranged along the same direction; in addition, because of the function of the limiting component, the box cover can not move upwards, so that when the roller pressing mechanism is used for rolling and bonding the box cover 120 on the edge part of the box plate 110, the box plate 110 can be prevented from moving upwards under stress, the assembly is not facilitated, and the product quality is influenced; moreover, since the outlet 351 is provided at the lower side of the accommodating portion 350, it is possible to move the cartridge board 110 downward out of the accommodating portion 350, facilitating the separation of the cartridge board 110 from the mold core when the assembled package 100 is unloaded from the mold core; furthermore, the box plate 110 is horizontally moved from the outside of the accommodating portion 350 into the accommodating portion 350 in the plate thickness direction, and the positions of the two box plates 110 can be respectively positioned by the accommodating portions 350 on both sides of the mold core, so that the box plate 110 is moved into the accommodating portion 350 in the plate thickness direction, because the accommodating portion 350 only has the freedom degree for the box plate 110 at the accommodating portion 350 to move out in the plate thickness direction and move downward under the action of the limiting member, and the box plate 110 is positioned inside the box skin 120 in the packaging box 100 when the wood skin is assembled with the box plate 110, so that it is not suitable to feed the box plate 110 into the accommodating portion 350 from the moving-out opening 351 from bottom to top, but to feed the box plate 110 into the accommodating portion 350 in the plate thickness direction, and the body of the mold core 300 is used to limit the moving-in position of the box plate 110, which is convenient and reliable.

The rolling mechanism aims to roll and bond the edge gluing part of the box skin 120 and the gluing part of the box plate 110, and the specific implementation scheme is as follows: referring to fig. 11 to 15, the roll pressing mechanism includes a pressing roll 500, the pressing roll 500 is disposed in a plate thickness direction of the box plate 110, and the degree of freedom of relative movement between the pressing roll 500 and the profiling mold core 300 in plate height and plate width directions is provided.

According to the above embodiment, there is a degree of freedom of relative movement between the molding core 300 and the press roller 500 in the height and width directions of the board, so that the relative movement between the press roller 500 and the molding surface of the molding core 300 realizes the roll bonding of the glued edge of the box skin 120 and the glued edge of the box board 110, and the preferred embodiment of the present application is: the molding mold core 300 is at least arranged on the frame 800 in a lifting way, two press rollers 500 are arranged, and the two press rollers 500 are at least movably arranged on the frame 800 along the width direction of the plate. In other words, at least the following embodiments are possible: firstly, the molding mold core 300 is installed in a lifting manner and can move up and down relative to the press roller 500, and the press roller 500 moves along the width direction of the plate, so that the box skin 120 is pressed and adhered to the edge of the box plate 110 along the contour of the molding surface by matching the relative movement of the two; secondly, the molding die core 300 is installed in a lifting way, and the compression roller 500 can move in the width direction of the plate and can also move in a lifting way; thirdly, the molding core 300 has the freedom of movement in the board width direction of the case board 110 and the lifting movement, and the pressing roller 500 has only the freedom of movement in the board width direction. The above three implementation forms are only a few of the many implementation forms, and other implementation forms that can be used to achieve the corresponding purposes can be applied to the present embodiment. In summary, the first embodiment is simpler in control of the movement path and the movement stroke of the molding core 300 and the compression roller 500 compared with the other two embodiments, so that the program control design is correspondingly simplified, the cost can be effectively reduced, and the simple movement and the simple program control are more reliable, thereby facilitating the adjustment, maintenance and even parameter recalibration in daily use.

Referring to fig. 11 and 12, the positioning mechanism 400 is composed of two positioning plates 410 which are horizontally disposed and can be close to and separated from each other, the upper plate surfaces of the two positioning plates 410 are provided with positioning shallow grooves 411 for positioning the casing skin 120, the casing skin 120 is flatly laid in the positioning shallow grooves 411 for positioning, and the end parts of the two positioning plates 410 close to each other are provided with the pressing rollers 500. By adjusting the two positioning plates 410 to approach each other, a complete positioning shallow groove 411 can be formed, and the positioning shallow groove 411 is used for accommodating the box skin 120 to be positioned; when the box skin 120 is moved into the shallow positioning groove 411 and is completely positioned, the molding mold core 300 can descend to tightly press the box skin 120 in the shallow positioning groove 411, then the two positioning plates 410 are adjusted to be away from each other, the two press rollers 500 can be driven to move away from each other along the lower side surface of the molding surface, and the box skin 120 and the lower side edge part of the box plate 110 are pressed and bonded together by the press rollers 500; when the distance between the two positioning plates 410 reaches a certain value, the positioning plates 410 stop moving and the distance between the two positioning plates 410 is kept unchanged, and at this time, the roller surfaces of the two pressing rollers 500 can respectively roll the two side surfaces of the molding surface along the width direction of the box plate 110 in the process of adjusting the molding mold core 300 to continuously descend, so that the box skin 120 and the two side edge parts of the box plate 110 along the width direction of the plate are rolled and bonded together.

After the skin 120 and the panel 110 are bonded together by rolling, the basic structure of the package 100 is assembled, but during the assembly process, the mold surface of the mold core 300 is disposed against the skin 120 until the package 100 is assembled. This makes it difficult to unload/remove the package 100, and therefore, in order to facilitate the unloading of the package 100, the preferred embodiments of the present embodiment are: as shown in fig. 8 to 10, the mold core 300 includes a front mold block 310, a middle mold block 320, and a rear mold block 330 sequentially arranged along the width direction of the plate, wherein the front mold block 310 and the rear mold block 330 are movably mounted on the middle mold block 320, and the movable mounting is at least capable of meeting the requirement of allowing the front mold block 310 and the rear mold block 330 to move along the width direction of the plate 110; the outer mold surfaces of the front mold 310, the middle mold 320 and the rear mold 330 form the molding surface, the molding surface can be tightly attached to the inner cavity of the assembled packing box 100, the box skin 120 and the box plate 110 to be assembled can be respectively limited in shape and position, the outer mold surfaces arranged along the plate height direction on the front mold 310 and the rear mold 330 can be moved and folded towards one side close to the middle mold 320, so that the occupied space of the whole molding surface in the assembled packing box 100 can be reduced, and the assembled packing box 100 is equivalently loose and clamped, so that the packing box 100 is separated from the molding mold core 300.

Specifically, referring to fig. 8 to 10, the front module 310 includes a front module body and a front module movable portion movably disposed on the front module body, the rear module 330 includes a rear module body and a rear module movable portion movably disposed on the rear module body, the front module movable portion and the rear module movable portion are in two states of a1 and a2, and the state of a1 is: the outer surfaces of the front mold movable part and the rear mold movable part and the lower surface of the middle mold block 320 form the molding surface; the a2 state is: the outer surfaces of the front mold moving part and the rear mold moving part move to a side close to the middle mold block 320, so that the molding cores 300 can be conveniently removed from the adhered packing box 100.

The embodiment adopted in the embodiment of the application is as follows: the gluing device for the box plate of the packing box comprises a transfer unit for pushing the box plate 110 to move, the moving direction of the box plate 110 is consistent with the plate thickness direction of the box plate 110, a gluing unit 220 is arranged on the periphery of the moving path of the box plate 110, a gluing part is arranged on the gluing unit 220, the outline shape of the gluing part is consistent with the outline shape of the part to be glued on the edge of the box plate 110, and the part to be glued is in sliding contact with the gluing part for gluing.

The gluing device for the box plate of the packing box provided by the invention pushes the box plate 110 to move through the transfer unit, the gluing unit 220 is arranged at the periphery of the moving path of the box plate 110, and the gluing part on the gluing unit 220 is used for gluing the part to be glued on the edge of the box plate 110. By adopting the scheme, the automation degree of the gluing operation of the box plate 110 is favorably realized, and compared with the traditional manual gluing mode, the gluing efficiency of the box plate 110 can be effectively improved; in addition, the product quality standard can be conveniently and uniformly controlled, and the problem of inconsistent quality caused by different factors such as operation methods, habits, modes and the like in the manual operation process is solved.

As shown in fig. 3 to 7, in particular, the gluing unit 220 comprises a glue-coated ribbon, the partial ribbon body sections of which form said gluing section by the shaping of the shaping member 223. In other words, the gluing unit 220 uses a gluing belt to glue the box board 110, and in order to make the local strip profile of the rubber-coated strip conform to the profile of the edge of the box plate 110 where the glue is to be applied, in the specific implementation, the outline shape of a local belt body of the rubber coating belt is molded by other structures, wherein the function of the molding member 223 is to mold the contour of the local belt body of the rubber-coated belt, so that the outline shape of the local belt body of the glue coating belt can be consistent with the outline shape of the position to be coated on the edge part of the box plate 110, the local tape body with the outline shape of the glue coating tape consistent with the outline shape of the part to be coated on the edge of the box plate 110 forms the glue coating part in the above embodiment, and the glue coating part is used for performing glue coating operation with the part to be coated of the box plate 110 in a sliding contact mode.

The glue coating tape is preferably capable of realizing continuous glue coating, and when a part of the tape bodies coats the part to be coated of the box plate 110, the other tape bodies can be used for adhering glue solution, so that the glue coating operation is circularly implemented, and the aim of coating the continuously conveyed box plate 110 can be fulfilled. For this reason, the preferred embodiments of this example are: as shown in fig. 5 to 7, the rubber-coated ribbon is an annular rubber-coated ribbon 221. Because the rubber coating belt is annular, when the rubber coating belt is implemented specifically, the rubber coating belt can be adjusted to rotate circularly, so that each part on the rubber coating belt can be circularly adhered with glue solution and the rubber coating operation can be implemented, and the purpose of circularly gluing the continuously conveyed box plates 110 is further facilitated.

Further, as shown in fig. 3 to 7, the adhesive tape further includes an adhesive tank 222, and the adhesive tape is partially immersed in the adhesive tank 222 and adheres to the adhesive. The process of circularly gluing the gluing tape comprises the following steps: the glue coating belt circularly moves, firstly, glue solution is adhered from the glue groove 222, when a local belt body to which the glue solution is adhered passes through the position of the plastic piece 223, glue is coated on the part to be coated on the edge of the box plate 110, when the local belt body is separated from the plastic piece 223, the local belt body enters the glue groove 222 again to be adhered with the glue solution, and the circular gluing operation is carried out in a reciprocating mode.

In actual gluing, only one side of the gluing belt is generally used for carrying out the operations of adhering glue solution and gluing, and the other side of the gluing belt is not used for carrying out the operations of adhering glue solution and gluing; moreover, the adhesive tape is used for realizing adhesive coating and adhesive solution adhering on one side of the tape surface, and only part of the tape surface is used for contacting with the box plate 110 along the tape width direction so as to coat the adhesive solution, so that if the adhesive solution is adhered on the whole tape surface and the adhesive coating operation is carried out, the problems of excessive adhesive solution adhering, uncontrollable adhesive coating range, uncontrollable adhesive coating uniformity, waste of the adhesive solution and the like are necessarily caused. To this end, the preferred embodiments of the examples herein are: referring to fig. 5 to 7, the adhesive tape includes an adhesive tape body 221a, and an adhesive layer 221b adhered with adhesive liquid is disposed on an outer surface of the adhesive tape body 221 a. In this embodiment, the adhesive tape is mainly divided into two parts, one is an adhesive tape body 221a, and the other is an adhesive layer 221b disposed on the outer surface of the adhesive tape body 221a, the adhesive layer 221b adheres the adhesive solution from the adhesive tank 222 and coats the adhesive solution on the portion to be coated on the edge of the box board 110, the adhesive tape body 221a is only used as a carrier of the adhesive layer 221b, and the adhesive layer 221b can be driven to circularly adhere the adhesive solution and coat the box board 110 by adjusting the adhesive tape body 221a to circularly move. Because the functions of adhering glue solution and coating glue solution can be independently divided onto the adhesive layer 221b, the functions can be accurately controlled by setting parameters such as the material, the specific structure, the external size and the like of the adhesive layer 221b during specific implementation.

On the basis of the above embodiment, the adhesive layer 221b is used for achieving the purpose of adhering and coating the adhesive solution, but if the adhesive solution adhered to the adhesive layer 221b is too much, in the process of coating the adhesive solution, the situation that the adhesive solution is extruded out and the extruded adhesive solution overflows along the bandwidth direction of the adhesive tape body 221a is likely to exist, so that not only is the accurate control of the adhesive coating width range influenced, but also the overflowing adhesive solution flows on the adhesive tape body 221a, so that a lot of trouble is brought to the cleaning of the adhesive tape, an operator needs to observe in real time to clean the adhesive tape, and once the adhesive solution is cured, the reuse effect of the adhesive tape is seriously influenced. To this end, the examples of the present application further take the embodiment: referring to fig. 6 and 7, the outer surface of the tape body 221a is provided with a shallow groove 221a1, the shallow groove 221a1 is arranged along the length direction of the tape body 221a, the glue layer 221b is arranged on the bottom of the shallow groove 221a1, the glue layer 221b is arranged higher than the shallow groove 221a1, and the width of the glue layer 221b is smaller than the groove width of the shallow groove 221a 1. The implementation principle of the embodiment is as follows: the shallow groove 221a1 is formed on the outer surface of the adhesive tape body 221a, then the adhesive layer 221b is arranged in the shallow groove 221a1, the adhesive layer 221b is higher than the shallow groove 221a1, so as to realize adhesive glue solution adhesion and coating glue solution, moreover, the width of the adhesive layer 221b is set to be smaller than the groove width of the shallow groove 221a1, so that the glue solution extruded out due to the sliding contact between the adhesive layer 221b and the box plate 110 in the gluing operation process is intercepted in the shallow groove 221a1 by the side wall of the shallow groove 221a1, thereby solving the problems that the overflowed glue solution flows around, is not convenient to clean and can not influence the using effect of the adhesive tape. The glue trapped in the shallow groove 221a1 can be adhered again by the glue layer 221b for recycling, and it should be noted that when the glue is not applied, it is preferable to clean and clear the adhesive tape to prevent the glue from being solidified and affecting the reuse.

Referring to fig. 5 to 7, when the molding member 223 is used to mold the adhesive tape, the constraining grooves 221a2 may be first formed on the two side surfaces of the adhesive tape body 221a, the constraining grooves 221a2 are formed along the length direction of the adhesive tape body 221a, the notch of the constraining groove 221a2 points to the outer side of the adhesive tape body 221a, then a plate is bent to be consistent with the contour shape of the portion to be coated with adhesive, that is, the above-mentioned molding member 223 is manufactured, and the molding member 223 is clamped in the constraining groove 221a2 to mold the adhesive tape.

Specifically, as shown in fig. 6 and 7, the cross section of the plastic mold 223 may be U-shaped, the ends of two sides of the U-shape are respectively provided with a bending part 611a arranged oppositely, the bending part 611a is snap-fitted with the constraining groove 221a2, and a part of the tape body 221a along the thickness direction is accommodated in the U-shaped recess.

In order to better control the gluing range and improve the consistency and uniformity of gluing, the present embodiment provides a further embodiment, referring to fig. 6 and 7, two strips 224 are disposed on the glue groove 222, the spacing between the two strips 224 is adapted to the dimension of the glue layer 221b along the tape width direction of the tape body 221a, two ends of the two strips 224 form an inlet and an outlet for the glue layer 221b to enter and move out between the two strips 224 for adhering, when the glue is adhered to the glue coating tape, the two strips 224 are located inside the shallow groove 221a1, and the glue layer 221b is located between the two strips 224. Because the two strips 224 are arranged according to the embodiment, the effective range of the contact between the glue layer 221b and the glue solution when the glue layer is adhered to the glue solution can be controlled, excessive glue solution is prevented from being adhered to the two outer sides of the glue layer 221b, the glue solution extruded during gluing and intercepted in the shallow groove 221a1 can be scraped, and the excessive glue solution finally flows back to the glue groove 222, so that the gluing range, the gluing consistency and the like can be controlled in a reliable manner, the waste of the glue solution can be reduced, the utilization rate of the glue solution is improved, and the workload for cleaning the glue tape is reduced.

In terms of realizing the continuous conveying of the cartridge board 110, the embodiments provided in the examples of the present application are: referring to fig. 3 and 4, the transfer unit includes an a guide 210 for guiding the cartridge board 110, the shape of the a guide 210 is consistent with the outer contour/partial outer contour of the cartridge board 110, the cartridge board 110 is pushed in the a guide 210 in a row code shape, an a gap 211 is disposed in the middle of the a guide 210, the adhesive layer 221b protrudes from the a gap 211 to form the adhesive coating portion, and the molding member 223 is disposed outside the a gap 211. The fact that the adhesive layer 221b protrudes from the a-shaped gap 211 means that the outer surface of the adhesive layer 221b protrudes into the a-shaped guide part 210, and the partial adhesive layer 221b protruding from the a-shaped gap 211 forms a gluing part, so that continuous gluing operation of passing box boards 110 is achieved, and the molding part 223 is arranged on the outer side of the a-shaped gap 211, so that on one hand, assembly and disassembly of a gluing tape can be facilitated, on the other hand, debugging of the position of the molding part 223 can be facilitated, and replacement and cleaning of the molding part 223 can be facilitated.

Although the above embodiment uses two spaced slats 224 in the glue groove 222 to control the range of the glue layer 221b adhering to the glue layer, the glue layer 221b may be supersaturated, so that more glue is extruded during the glue application operation, once the amount of glue extruded is too large at a moment, the glue may move out of the shallow groove 221a1, and the accurate control of the glue application range and the glue application uniformity may be affected. To this end, the embodiments of the present application provide further solutions: referring to fig. 6 and 7, a scraper for spraying the glue solution on the adhesive layer 221b is provided at the outlet between the two plates 224. By providing a scraper at the outlet formed between the two plates 224, the adhesive layer 221b can be scraped after the adhesive layer 221b is adhered from the adhesive tank 222 and when the adhesive layer 221b is moved out of the two plates 224, so that the adhesive layer 221b is adhered with an appropriate amount of adhesive, which can be beneficial to the subsequent preparation of controlling the thickness, uniformity and adhesive application range of the adhesive. In specific implementation, the amount of the adhesive retained by the adhesive layer 221b can be adjusted by adjusting the distance between the scraper and the adhesive tape body 221a in the tape thickness direction.
