[0002] In the prior art, the solution for the side wall veneer paper of the barrel-type structure is to first laminat the veneer paper and transport it on the platform, and then use mechanical positioning to move the barrel-type structure to adapt to the flat veneer paper for positioning and pasting, or use a visual system to find the feature points on the veneer paper, and then send a command containing coordinate information to the robot, and the robot or mold transports the barrel-type structure and the flat veneer paper.

[0003] This solution is suitable for situations where the area of ​​facial tissue is large and the cost is not a consideration, because if the area of ​​facial tissue is small, it is difficult to laminat the facial tissue and then lay it flat on the conveying platform with the adhesive side facing up; this solution is also not suitable for barrel structures with more complex structures, such as the intermediate product produced in the front stage of a new barrel box production process, which has two barrel structures, one is the barrel body and the other is the barrel cover, which are connected by facial tissue. In the back stage of the production process, the smaller facial tissue needs to be attached to the smaller barrel cover. If the existing technology model is adopted, the robot or mold needs to additionally consider the fragility of the connected facial tissue when transporting the intermediate product, increasing the development cost.

[0041] For wine boxes with special structures, due to their structural characteristics, the functions and structures of the corresponding positions of the surface paper are also different. It is necessary to wrap and attach the barrel body and the barrel cover first, and then apply the veneer paper to the other side walls of the barrel cover separately. In order to make the barrel cover fit better, it is also necessary to stick a reinforcing plate inside the barrel cover. Therefore, the existing barrel cover veneer paper process is no longer suitable for wine boxes with special structures.

[0042] Please refer to Figure 1 The present invention provides a barrel-shaped structural box 200, which is composed of a barrel body 201 and a barrel cover 202, wherein the barrel cover 202 includes two side panels 2021 arranged opposite to each other, and a front panel 2022 connecting the two side panels 2021. Due to its special structural characteristics, the barrel-shaped structural box 200 needs to be attached with a side paper 300 to the side panels 2021 of the barrel cover 202 and a front reinforcing panel 400 to the front panel 2022 of the barrel cover 202. In view of this, the present invention provides a barrel cover patching process for a barrel-shaped structural box. Figures 2 to 6 The present invention provides an embodiment of the barrel cover patching process of the barrel-shaped structure box.

[0043] See also Figures 2 to 6 The barrel cover patching process of the barrel-shaped structure box includes:

[0044] The barrel-shaped structural box 200 further includes a barrel body 201, and the barrel body 201 and the barrel cover 202 are conveyed on the conveyor line in an open state, and the opening of the barrel cover 202 faces upwards of the conveyor line;

[0045] The conveyor line is equipped with a side paper pasting station A, a side panel bubble pressing station B, a side paper inner folding station C, a front reinforcement board pasting station D, and a front panel bubble pressing station E;

[0046] Wherein, at the side paper pasting station A, two pieces of side paper 300 are pasted on the outer sides of the two side panels 2021 respectively;

[0047] At the side panel bubble pressing station B, the two side panels 2021 with the side paper 300 attached thereto are respectively bubble pressed;

[0048] At the side paper inward folding station C, the remaining edge of the side paper 300 protruding from the side panel 2021 is folded inwardly and attached to the inner side of the side panel 2021 on the corresponding side;

[0049] At the front reinforcing plate attaching station D, attach the front reinforcing plate 400 to the inner side of the front plate 2022;

[0050] In the front plate foaming station E, the front plate 2022 to which the front reinforcing plate 400 is attached is subjected to a foaming treatment.

[0051] In the technical solution of the present invention, at the side paper pasting station A, two pieces of side paper 300 are correspondingly attached to the outer sides of the two side panels 2021; at the side panel bubble pressing station B, the two side panels 2021 pasted with the side paper 300 are respectively subjected to bubble pressing treatment; at the side paper folding station C, the remaining edges of the side paper 300 protruding from the side panel 2021 are folded inwardly and attached to the inner side of the side panel 2021 on the corresponding side; at the front reinforcement plate pasting station D, the front reinforcement plate 400 is attached to the inner side of the front panel 2022; at the front panel bubble pressing station E, the front panel 2022 with the front reinforcement plate 400 attached is subjected to bubble pressing treatment, so as to achieve the laminating of the surface paper on the outer side of the barrel cover 202 and the laminating of the reinforcement plate on the inner side of the barrel cover 202.

[0052] Specifically, at the side paper pasting station A, two veneer paper devices are respectively arranged on both sides corresponding to the conveyor line, and each of the veneer paper devices includes a side paper gluing mechanism 1 and a side paper attaching mechanism 2; the two pieces of side paper 300 are transferred to the side paper pasting station A, and the side paper attaching mechanism 2 transfers the side paper 300 on the corresponding side to the side paper gluing mechanism 1 on the corresponding side for gluing, and then the glued side paper 300 is attached to the outer side of the side panel 2021 on the corresponding side.

[0053] It should be noted that two veneer paper devices are correspondingly arranged on the conveying line, so that the veneer paper operation can be performed on the two side panels 2021 of the barrel cover 202 at the side veneer paper veneer station A at the same time. In this way, not only the station layout is reduced, but also the process is reduced, thereby improving production efficiency.

[0054] More specifically, the side paper gluing mechanism 1 includes a side paper gluing roller, which is used to glue the side of the side paper 300 facing the side paper gluing roller; the side paper attaching mechanism 2 includes a movably arranged side panel suction cup assembly 21, after the side panel suction cup assembly 21 absorbs the other side of the side paper 300 and rolls along the horizontal tangent direction of the side paper gluing roller and dips in glue, the side panel suction cup assembly 21 is swung to a vertical state to attach the glued side of the side paper 300 to the outer side of the side panel 2021.

[0055] It should be noted that, in the initial state, the side paper 300 in the silo is moved to the temporary platform by a mechanical module with a suction cup, and the side paper attaching mechanism 2 sucks the upper surface of the side paper 300 from the temporary platform, so that its lower surface first passes over the side paper gluing roller and rolls from the horizontal tangent to the glue dipped on the surface of the side paper gluing roller to complete the gluing, and then the side paper attaching mechanism 2 continues to flip the glued side paper 300 into a vertical state and then transfer and attach it to the outside of the side panel 2021. In this embodiment, a set of side paper gluing mechanism 1 and side paper attaching mechanism 2 are respectively arranged on both sides of the conveyor line, which reduces the development cost and is conducive to the universalization of spare parts. This embodiment can not only transport and transfer the side paper 300 but also realize the function of changing the posture of the side paper 300, which can solve the needs of the same type of upright pasting of the side paper 300.

[0056] In order to further improve the attachment quality of the side paper 300, in the present invention, the barrel-shaped structure box 200 with the side paper 300 attached is transferred to the side panel bubble pressing station B; at the side panel bubble pressing station B, two side panel bubble pressing mechanisms 3 and a movable inner mold above the conveyor line are respectively arranged on both sides corresponding to the conveyor line, and the two side panel bubble pressing mechanisms 3 are respectively arranged corresponding to the two side panels 2021, and each side panel bubble pressing mechanism 3 includes a side pressing plate 31, and the movable inner mold first extends into the interior of the barrel cover, and the side pressing plate 31 squeezes the barrel cover on the outside of the barrel cover to press the side panel 2021 with the side paper 300 attached on the corresponding side. Bubble pressing treatment, that is, by setting the side panel bubble pressing mechanism 3 on the side panel bubble pressing station B, the side panel 2021 with the side paper 300 affixed is subjected to bubble pressing treatment to avoid the side panel 2021 from having debonding, bubbling and other undesirable phenomena after the side paper 300 is affixed, thereby improving the affixing quality of the side paper 300; furthermore, by setting two side panel bubble pressing mechanisms 3 on both sides of the conveyor line, the two side panels 2021 of the barrel cover 202 are subjected to bubble pressing treatment at the same time, thereby not only ensuring the affixing quality of the side paper 300, but also reducing the bubble pressing time and improving the production efficiency.

[0057] In the present invention, a front reinforcing plate affixing device is provided at the front reinforcing plate affixing station D, and the front reinforcing plate affixing device includes a front reinforcing plate gluing mechanism 5 and a front reinforcing plate attaching mechanism 6; the front reinforcing plate attaching mechanism 6 transfers the front reinforcing plate 400 to the front reinforcing plate gluing mechanism 5 for gluing; and then the glued front reinforcing plate 400 is attached to the inner side of the front plate 2022.

[0058] The front reinforcing plate gluing mechanism 5 includes a front reinforcing plate gluing roller to apply glue to the side of the front reinforcing plate 400 facing the front reinforcing plate gluing roller; the front reinforcing plate attaching mechanism 6 includes a movably arranged front plate suction cup assembly 61, the front plate suction cup assembly 61 sucks the other side of the front reinforcing plate 400 and rolls along the horizontal tangent direction of the front reinforcing plate gluing roller to dip in glue, and the front plate suction cup assembly 61 then swings to a vertical state to attach the glued side of the front reinforcing plate 400 to the inner side of the front plate 2022.

[0059] It should be noted that, in the initial state, the front reinforcing plate 400 in the silo is moved to the temporary platform by the mechanical module with a suction cup, and the front reinforcing plate attaching mechanism 6 sucks the upper surface of the front reinforcing plate 400 from the temporary platform, so that its lower surface passes above the front reinforcing plate glue coating roller and rolls from the horizontal tangent to the glue dipped on the surface of the front reinforcing plate glue coating roller to complete the gluing, and then the front reinforcing plate attaching mechanism 6 continues to flip the glue-coated front reinforcing plate 400 into a vertical state and then transfer and attach it to the inner side of the front plate 2022. In this embodiment, a set of front reinforcing plate gluing mechanism 5 and front reinforcing plate attaching mechanism 6 are set on one side of the conveyor line, which reduces the development cost and is conducive to the universalization of spare parts. This embodiment can not only transport and transfer the front reinforcing plate 400 but also realize the function of changing the posture of the front reinforcing plate 400, which can solve the needs of the same type of vertically pasted front reinforcing plates 400.

[0060] In order to further improve the attachment quality of the front reinforcing plate 400, in the present invention, the barrel-shaped structure box 200 with the front reinforcing plate 400 attached is transferred to the front plate bubble pressing station E; a front plate bubble pressing mechanism 7 is provided at the front plate bubble pressing station E, and the front plate bubble pressing mechanism 7 is provided corresponding to the front plate 2022. The front plate bubble pressing mechanism 7 includes a front pressing plate 71, which is used to perform bubble pressing treatment on the front plate 2022 with the front reinforcing plate 400 attached on the corresponding side. That is to say, by arranging the front plate bubble pressing mechanism 7 at the front plate bubble pressing station E, the front plate 2022 with the front reinforcing plate 400 attached is subjected to bubble pressing treatment, so as to avoid undesirable phenomena such as debonding and bubbling of the front plate 2022 after the front reinforcing plate 400 is attached, thereby improving the attachment quality of the front reinforcing plate 400.

[0061] In order to further improve the aesthetics of the barrel cover 202, the side paper 300 also includes a side paper margin formed by protruding from the corresponding side panel 2021; the barrel-shaped structural box 200 with the side paper 300 affixed is transferred to the side paper inward folding station C, at which two side paper inward folding mechanisms 4 are respectively arranged on both sides of the corresponding conveyor line, each of which includes a shovel plate 41 and a side panel inner mold 42, the shovel plate 41 is used to shovel the side paper margin on the corresponding side inward, and the side panel inner mold 42 is used to fold the side paper margin after the corresponding side is flattened inward and attach it to the inner side of the corresponding side panel 2021.

[0062] It should be noted that after the side paper 300 is attached to the outer side of the side panel 2021, there is a risk of debonding at the end of the side paper 300 close to the opening of the barrel cover 202, which not only affects the appearance but also reduces the attachment quality of the side paper 300. Therefore, in the present invention, the side paper 300 is provided with a side paper margin protruding from the corresponding side panel 2021, and the side paper inward folding mechanism 4 is provided on the side paper inward folding station C, and the side paper margin is folded inwardly and attached to the inner side of the side panel 2021, that is, the side paper 300 covers the edge of the opening side of the barrel cover 202. In this way, not only the risk of debonding of the side paper 300 is eliminated, but also the appearance of the barrel cover 202 is improved; furthermore, by respectively providing two side paper inward folding mechanisms 4 on both sides of the conveyor line, the two side panels 2021 of the barrel cover 202 can be subjected to the surface paper inward folding processing at the same time, thereby reducing the time consumed in the inward folding process and improving production efficiency.

[0063] In order to further improve the production efficiency, in the present invention, a carrier 8 is provided on the conveyor line for transporting the barrel-type structure box 200, and the carrier 8 includes a first bearing portion 81 and a second bearing portion 82 arranged at intervals, and the first bearing portion 81 and the second bearing portion 82 are used to respectively carry the barrel cover 202 and the barrel body 201, so that the barrel-type structure box 200 is in a state where the barrel cover 202 opens upward and the barrel body 201 is flipped open relative to the barrel cover 202; by providing the carrier 8, not only the carrying operation of the barrel cover 202 and the barrel body 201 can be completed, but also the transfer operation of the barrel cover 202 and the barrel body 201 can be completed, which not only has a simple structure and is easy to operate, but also can improve production efficiency.

After the folding of the side paper edge is completed, the shoveling plate 41 moves toward the side away from the side panel 2021. At this time, the side panel inner mold 42 moves downward to press the side paper edge against the inner side of the side panel 2021. In this way, the folding and bonding of the side paper edge is completed.

[0071] In the present invention, a front panel bubble pressing mechanism 7 is further provided at the position corresponding to the front panel bubble pressing station E. The front panel bubble pressing mechanism 7 includes a front panel inner mold assembly and a front pressure plate assembly, which is used to perform bubble pressing treatment on the bonding portion between the front panel 2022 and the pre-glued reinforcement plate to avoid defects such as debonding and bubbles, thereby improving the surface paper bonding quality.

[0072] Specifically, the front pressure plate assembly includes a front pressure plate 71, which can move left and right, and the front panel inner mold assembly includes a front panel inner mold 72, which can move up and down. When the reinforcement plate is attached to the front panel 2022, the barrel-shaped open box is transferred to the front panel bubble pressing station E, and the front panel inner mold 72 moves down into the barrel cover 202. The front pressure plate 71 moves toward the side close to the front panel 2022 and clamps the front panel 2022 with the front panel inner mold 72 to perform bubble pressing treatment on the joint between the front panel 2022 and the pre-coated reinforcement plate to avoid defects such as debonding and bubbles, thereby improving the quality of surface paper bonding.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
