Description

Technical Field

[0001] This invention relates to equipment for producing paper products, and particularly to equipment for mounting folding boxes. Background Technology

[0002] Folding boxes can be unfolded into cardboard boxes for packaging through their folding structure, or folded into a flat shape for easy storage and transportation. Currently, the main structure of a folding box includes a main board and two side panels (i.e., side walls). When unfolded, the main board and side walls work together to form a cardboard box. The main board is usually a shell structure, which includes multiple cardboard pieces in the middle and face paper pasted on the front and back of these middle cardboard pieces. An outer laminating machine (including the main conveyor belt for shell laminating) lathes the face paper on the front of the cardboard, and an inner laminating machine (including the main conveyor belt for shell laminating) lathes the face paper on the back of the cardboard. The outer laminating machine and the inner laminating machine can also be connected to form a production line, such as the CN215040809U shell production line.

[0003] In addition, the side walls are folded boards, such as three-part or five-part boards, and usually one side of the board is also pasted on both sides. For example, the folding board produced in conjunction with CN112440516A folding board cover machine, etc., has a thicker middle section (the middle board) of the side wall and thinner side sections. After the main board and side walls are made separately, they are assembled. The edges of the middle section of the side wall are glued to the main board (its outer surface of the face paper), and the joint is exposed. Moreover, the assembly process is done manually, which is inefficient and of poor quality. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the technical problem solved by the present invention is to provide a folding box inner mounting machine that combines side wall assembly and inner mounting, connects the side wall and the main board during the inner mounting process, and makes the assembly connection point built-in to avoid exposure, with relatively better quality, higher stability of mechanized operation and improved assembly efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a folding box mounting machine, including a paper feeding platform, a gluing mechanism, a main conveyor belt for mounting paper and a mounting mechanism. The paper feeding platform and the gluing mechanism are connected through a paper feeding device. The output side of the gluing mechanism is connected to the input side of the main conveyor belt for mounting paper. The main conveyor belt for mounting paper has a mounting station, and the mounting mechanism is connected to the mounting station. The main conveyor belt for mounting paper also has a side wall assembly station, which is located between the gluing mechanism and the mounting station. The side wall assembly station is connected to the side wall assembly mechanism.

[0006] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0007] For example, the paper feeding platform includes a lifting support, the paper feeding device includes a feeder, the gluing mechanism includes a gluing roller, and the mounting mechanism includes a mounting robot, which in turn includes a board-picking nozzle. A magnetic sheet and / or iron sheet assembly station can also be provided between the gluing mechanism and the side wall assembly station. The output side of the main conveyor belt for the paper mounting casing is connected to the roller pressing mechanism.

[0008] Further optimization involves adding a side wall adhesive application station between the side wall assembly station and the mounting station. This station is equipped with a side wall adhesive application device; for example, the device includes an adhesive application component.

[0009] For example, the side wall assembly mechanism includes a transfer robot with a lifting suction nozzle; the side wall assembly mechanism also includes a first side wall feeding device, a second side wall feeding device, a first side wall conveyor belt, and a second side wall conveyor belt. The first side wall feeding device has a first output end, the second side wall feeding device has a second output end, the first side wall conveyor belt has a first input station and a first delivery station, the first output end is connected to the first input station, the second side wall conveyor belt has a second input station and a second delivery station, the second output end is connected to the second input station, and the first delivery station and the second delivery station are respectively connected to the side wall assembly station through the transfer robot.

[0010] For example, the conveying directions of the first and second sidewall conveyor belts are parallel, and the first and second delivery stations are arranged side by side. The first and second sidewall conveyor belts are located on the same side of the main paper mounting conveyor belt. The conveying directions of the first and second sidewall conveyor belts are orthogonal to the conveying direction of the main paper mounting conveyor belt, which is a longitudinal conveying direction, while the first and second sidewall conveyor belts are transverse conveying directions.

[0011] For example, a first sidewall feeding device includes a first support frame, a first sidewall stacking bin, and a first feeding conveyor belt. The first feeding conveyor belt and the first sidewall stacking bin are mounted on the first support frame. The first feeding conveyor belt is positioned at the bottom of the first sidewall stacking bin. The first sidewall stacking bin includes a first side baffle component, and a first feeding outlet is provided between the bottom end of the first side baffle component and the first feeding conveyor belt. Alternatively, the feeding direction of the first feeding conveyor belt is orthogonal to the conveying direction of the first sidewall conveyor belt. For example, a second sidewall feeding device includes a second support frame, a second sidewall stacking bin, and a second feeding conveyor belt. The second feeding conveyor belt and the second sidewall stacking bin are mounted on the second support frame. The second feeding conveyor belt is positioned at the bottom of the second sidewall stacking bin. The second sidewall stacking bin includes a second side baffle component, and a second feeding outlet is provided between the bottom end of the second side baffle component and the second feeding conveyor belt. The feeding direction of the second feeding conveyor belt is orthogonal to the conveying direction of the second sidewall conveyor belt.

[0012] For example, the first sidewall conveyor belt is equipped with a first side pusher and a first side guide, which are located at the first delivery station. The first side guide and the first side pusher are located on the left and right sides of the first sidewall conveyor belt, respectively. The first sidewall conveyor belt, the first side pusher, and the first side guide are connected to the first frame of the sidewall assembly mechanism. The second sidewall conveyor belt is equipped with a second side pusher and a second side guide, which are located at the second delivery station. The second side guide and the second side pusher are located on the left and right sides of the second sidewall conveyor belt, respectively. The second sidewall conveyor belt, the second side pusher, and the second side guide are connected to the second frame of the sidewall assembly mechanism.

[0013] In addition, the position of the first frame along the feeding direction of the first side wall feeding device is adjusted and / or the position of the second frame along the feeding direction of the second side wall feeding device is adjusted; the position of the first side wall feeding device along its feeding direction is adjusted; the position of the second side wall feeding device along its feeding direction is adjusted.

[0014] Further optimizations include a first drive motor on the first sidewall conveyor belt, a second drive motor on the second sidewall conveyor belt, a first photoelectric sensor above the first sidewall conveyor belt, and a second photoelectric sensor above the second sidewall conveyor belt. The first photoelectric sensor is connected to the first drive motor, and the second photoelectric sensor is connected to the second drive motor.

[0015] For example, the transfer robot can be an industrial robot, with a camera mounted above the main conveyor belt for paper mounting, and the camera connected to the transfer robot. The transfer robot may also include a base, a first rotating arm, a second rotating arm, and a rotating lifting vertical shaft. The first rotating arm is connected to the base, the second rotating arm is connected to the first rotating arm, and the rotating lifting vertical shaft is mounted on the second rotating arm. A suction nozzle bracket is installed at the lower end of the rotating lifting vertical shaft, and the lifting suction nozzle is mounted and connected to the suction nozzle bracket. The camera is positioned at the side wall assembly station of the main conveyor belt for paper mounting.

[0016] The beneficial effects of this invention are as follows: In this folding box mounting machine, the main conveyor belt is equipped with a side wall assembly station, and a corresponding side wall assembly mechanism is connected to the side wall assembly station to cooperate with the side wall assembly; moreover, the side wall assembly station is located before the mounting station and after the gluing mechanism. The face paper is glued first, then the side wall assembly is completed, and then the cardboard and face paper of the main board are mounted. In the conventional internal mounting process, the side wall and the main board are assembled and connected. The side wall assembly is combined with the internal mounting. The side wall assembly connection is built-in to avoid exposure, resulting in better quality, higher stability of mechanized operation, and improved assembly efficiency. This overcomes the problems of traditional manual assembly, where the middle section of the side wall connection is exposed on the main board. Therefore, this invention has substantial features and progress compared with the prior art. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the implementation of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Referring to the accompanying drawings, the folding box mounting machine in this embodiment includes a paper feeding table 1, an adhesive application mechanism 2, a main conveyor belt for paper mounting 3, and a mounting mechanism 4.

[0026] In this design, the paper feeding platform 1 and the gluing mechanism 2 are connected via a paper feeding device. The paper feeding device feeds the paper from the paper feeding platform 1 into the gluing mechanism 2. The output side of the gluing mechanism 2 is connected to the input side of the main conveyor belt 3 for mounting the outer casing. After being glued by the gluing mechanism 2, the paper is output onto the main conveyor belt 3 for mounting the outer casing. The main conveyor belt 3 (hereinafter referred to as the main conveyor belt 3) then carries the paper forward. The main conveyor belt 3 has a mounting station 6, and a mounting mechanism 4 is connected to the mounting station 6. When the paper is carried forward by the main conveyor belt 3 to the mounting station 6, the mounting mechanism 4 places the cardboard portion of the main board (such as the main board after external mounting) onto the paper for mounting. The mounting mechanism 4 can be a positioning machine or a cover machine, etc. This is a mature technology and will not be described in detail further.

[0027] In this invention, the main conveyor belt 3 for mounting paper also has a side wall assembly station 7. The side wall assembly station 7 is located between the gluing mechanism 2 and the mounting station 6. Before mounting, the face paper on the main conveyor belt 3 is first assembled at the side wall assembly station 7. The side wall assembly station 7 is connected to a side wall assembly mechanism 8. The side wall assembly mechanism 8 works together to connect the side wall assembly to the face paper on the main conveyor belt 3, and the side wall and the face paper are glued together.

[0028] Its working principle is as follows: after the face paper is glued, it is conveyed forward by the main conveyor belt 3. It first stops at the side wall assembly station 7 to cooperate in the side wall assembly, and then stops at the mounting station 6 to mount the cardboard part of the main board with the face paper to complete the production of the folding board.

[0029] In this folding box mounting machine, the main conveyor belt 3 is equipped with a side wall assembly station 7, and a corresponding side wall assembly mechanism 8 is connected to the side wall assembly station 7 to cooperate with the side wall assembly. Moreover, the side wall assembly station 7 is located before the mounting station 6 and after the gluing mechanism 2. The face paper is glued first, then the side wall assembly is completed, and then the cardboard and face paper of the main board are mounted. In the conventional internal mounting process, the side wall and the main board are assembled and connected. The side wall assembly is combined with the internal mounting. The connection of the side wall assembly is built in to avoid exposure, the quality is relatively better, the stability of mechanized operation is higher, and the assembly efficiency is improved. This overcomes the problems of traditional manual assembly and the middle section of the side wall connection being exposed on the main board.

[0030] Based on the above embodiments, the following optimizations or further explanations can be made.

[0031] For example, the paper feeding platform 1 includes a lifting bracket, the paper feeding device includes a feeder, the gluing mechanism 2 includes a gluing roller 11, and the mounting mechanism 4 includes a mounting robot, which includes a board-picking nozzle. A magnetic sheet and / or iron sheet assembly station is also provided between the gluing mechanism 2 and the side wall assembly station 7. The output side of the main conveyor belt 3 for paper mounting is connected to the roller pressing mechanism 14. There are many possible configurations; appropriate mature technologies can be selected based on requirements, and will not be elaborated further. The mounting mechanism 4 can also be connected to an external mounting machine to form a production line.

[0032] In addition, a side wall gluing station 15 is provided between the side wall assembly station 7 and the mounting station 6. Before the side wall assembled on the face paper is conveyed to the mounting station 6 by the main conveyor belt 3, it can stop at the side wall gluing station 15 for gluing. Glue is applied to the upper surface of the side wall on the face paper of the main conveyor belt 3. After gluing, it is conveyed to the mounting station 6 for mounting. The connection between the side wall and the cardboard part of the main board placed above is more secure, and the side wall is clamped more tightly by the lower face paper and the upper main board cardboard part. The side wall gluing station 15 is equipped with a side wall gluing device 16, which is used to apply glue to the side wall. The side wall gluing device 16 includes gluing and applying components (such as a glue gun). Two gluing and applying components can be set up to apply glue to the side walls on both sides of the face paper separately, which is more efficient. The gluing and applying components can also be adjusted to the left and right (adjusted by a screw and nut mechanism) to meet the gluing requirements of different sizes and positions.

[0033] For example, the side wall assembly mechanism 8 includes a transfer robot 18, which has a lifting suction nozzle 19. During operation, the lifting suction nozzle 19 moves and lifts to assist in transferring the side wall. The lifting suction nozzle 19 connects to an air source; it sucks in the side wall when inhaling and releases it when de-inhaling. The transfer robot 18 is a mature technology, and this invention uses it for side wall transfer assembly. For example, the transfer robot 18 can be an industrial robot (such as a four-axis robot). As shown in the figure, the transfer robot 18 also includes a base 66, a first rotating arm 67, a second rotating arm 68, and a rotating lifting vertical shaft 69. The first rotating arm 67 is connected to the base 66 for relative rotation, the second rotating arm 68 is connected to the first rotating arm 67 for rotation, and the rotating lifting vertical shaft 69 is mounted on the second rotating arm 68 for rotation and lifting. It can be configured with a corresponding motor to drive each rotation and lifting action. A suction nozzle support is provided at the lower end of the rotating lifting vertical shaft 69. The frame 70 is used to install multiple lifting suction nozzles 19. The lifting suction nozzles 19 are mounted and connected to the suction nozzle bracket 70. The lifting suction nozzles 19 are conveniently adjusted in position on the suction nozzle bracket 70 to meet the needs of sidewall transfer and assembly of different specifications. The lifting suction nozzles 19 will move on the suction nozzle bracket 70 with the corresponding rotation and lifting of the first rotating arm 67, the second rotating arm 68 and the rotating lifting vertical shaft 69. Thus, the transfer robot 18 can pick up (move) the sidewall and place it on the glued face paper on the main conveyor belt 3 for assembly. Moreover, the relative position of the sidewall can be adjusted by corresponding rotation to ensure more accurate positioning during sidewall assembly and connection. The sidewall assembly mechanism 8 also includes a first sidewall feeding device 20, a second sidewall feeding device 21, a first sidewall conveyor belt 22 and a second sidewall conveyor belt 23.

[0034] The main board of the folding box is connected to the two side walls. The first side wall feeding device 20 supplies material to one side wall, and the second side wall feeding device 21 supplies material to the other side wall. The first side wall feeding device 20 has a first output end 24, from which the side wall outputs material. The second side wall feeding device 21 has a second output end 25, from which the side wall outputs material.

[0035] The first sidewall conveyor belt 22 has a first input station 26 and a first delivery station 27. The first output end 24 is connected to the first input station 26. The sidewalls output from the first output end 24 of the first sidewall feeding device 20 will enter the first sidewall conveyor belt 22 at the first input station 26. The sidewalls are conveyed by the first sidewall conveyor belt 22 to the first delivery station 27 (at which point the sidewalls are delivered to the position) and wait for the transfer robot 18 (with its lifting suction nozzle 19) to pick them up and transfer them.

[0036] The second sidewall conveyor belt 23 has a second input station 28 and a second delivery station 29. The second output end 25 is connected to the second input station 28. The sidewalls output from the second output end 25 of the second sidewall feeding device 21 will enter the second sidewall conveyor belt 23 at the second input station 28. The sidewalls are conveyed by the second sidewall conveyor belt 23 to the second delivery station 29 (at this time, the sidewalls are delivered to the position) and wait for the transfer robot 18 (with its lifting suction nozzle 19) to pick them up and transfer them.

[0037] The first delivery station 27 and the second delivery station 29 are respectively connected to the side wall assembly station 7 of the main conveyor belt 3 for the outer casing mounting via transfer robots 18. The two side walls at the first delivery station 27 and the second delivery station 29 are picked up (moved) by the transfer robots 18 and placed on the main conveyor belt 3 for mounting. They are then assembled with the face paper on the main conveyor belt 3 at the side wall assembly station 7. The side walls are placed on the face paper and then glued together. Subsequently, the cardboard portion of the main board (such as the completed outer board) is placed on top of the face paper on the main conveyor belt 3 to complete the outer casing mounting, forming the main board of the folding box.

[0038] The working principle of the side wall assembly mechanism 8 is as follows: after the two side walls are conveyed to their positions by the first side wall conveyor belt 22 and the second side wall conveyor belt 23 respectively, the two side walls will be picked up and transferred to the main conveyor belt 3 for the outer shell mounting by the transfer robot arm 18. The two side walls are placed down onto the face paper (with glue on the surface) on the main conveyor belt 3 for the outer shell mounting, thus completing the face paper assembly connection between the side wall and the main board. Subsequently, the cardboard part of the main board (such as the main board after the outer mounting is completed) is placed on the face paper to complete the outer shell mounting and form the main board of the folding box. At this time, the side wall has already been assembled and connected to the face paper. When the main board of the folding box is made later, the assembly connection can be further clamped, that is, the assembly connection will be clamped and fixed by the cardboard part of the face paper and the main board.

[0039] In the side wall assembly mechanism 8, the transfer robot 18, in conjunction with the transfer robot, picks up the two side plates that have been delivered to the position and transfers them to the main conveyor belt 3 for mounting the outer casing. The two side walls are transferred downward by the transfer robot 18 and placed onto the face paper (with glue on the surface) on the main conveyor belt 3 for mounting the outer casing, completing the face paper assembly connection between the side wall and the main body. This enables the assembly of the side walls of the folding box, achieving mechanized operation, stable product quality, relatively better quality, higher operational stability, and improved assembly efficiency, solving various problems that occur in manual assembly. Moreover, the side walls connected to the face paper are subsequently mounted as the main conveyor belt 3 for mounting the outer casing. After mounting, the connection between the side wall and the face paper will be clamped by cardboard (such as the cardboard part of the main body, for example, the main body after external mounting). The side wall assembly connection will be further fixed by the cardboard part of the face paper and the main body, which can help to internalize the side wall assembly connection and prevent it from being exposed.

[0040] The conveying directions of the first side wall conveyor belt 22 and the second side wall conveyor belt 23 can be parallel, meaning their conveying directions are parallel to each other. The first delivery station 27 and the second delivery station 29 are arranged side by side, without any distinction between front and back. After the side walls are delivered into place, the two side walls of the first delivery station 27 and the second delivery station 29 can be aligned side by side, with their relative positions aligned to facilitate subsequent transfer and alignment with the left and right sides of the face paper on the main conveyor belt 3 for mounting paper, and corresponding connection. Moreover, the side-by-side arrangement structure is relatively compact.

[0041] It can be further optimized. The first side wall conveyor belt 22 and the second side wall conveyor belt 23 are configured on the same side of the main conveyor belt 3 for the paper mounting, which is relatively reasonable. A set of lifting suction nozzles 19 (including multiple ones) on the same transfer robot 18 can simultaneously transfer the two side walls on the first side wall conveyor belt 22 and the second side wall conveyor belt 23 to the main conveyor belt 3 for bonding and assembly with the face paper on the main conveyor belt 3. In particular, the conveying directions of the first side wall conveyor belt 22 and the second side wall conveyor belt 23 are parallel, and the first delivery station 27 and the second delivery station 29 are set up side by side. The two side walls can be transferred together by one transfer robot 18, which is efficient and the relative positions of the side walls and the face paper are more accurate. The transfer assembly can be carried out by one transfer robot 18, or by two transfer robots 18 respectively corresponding to the first side wall conveyor belt 22 and the second side wall conveyor belt 23. That is, the first side wall conveyor belt 22 and the second side wall conveyor belt 23 can share the transfer robot 18 or each can be equipped with a transfer robot 18 to connect with the main conveyor belt 3 for paper mounting.

[0042] Furthermore, it can be optimized that the conveying directions of the first side wall conveyor belt 22 and the second side wall conveyor belt 23 are orthogonal to the conveying direction of the main conveyor belt 3 for paper mounting. There is sufficient space next to the first side wall conveyor belt 22 and the second side wall conveyor belt 23 for component assembly and material replenishment during operation. For example, in the figure, the conveying direction of the main conveyor belt 3 for paper mounting is the longitudinal conveying direction, and the conveying directions of the first side wall conveyor belt 22 and the second side wall conveyor belt 23 are the transverse conveying directions.

[0043] For example, the first sidewall feeding device 20 includes a first support frame 30, a first sidewall stacking bin 31, and a first feeding conveyor belt 32. The first feeding conveyor belt 32 and the first sidewall stacking bin 31 are mounted on the first support frame 30 for installation and connection. The first feeding conveyor belt 32 is positioned at the bottom of the first sidewall stacking bin 31. The first feeding conveyor belt 32 can support the stacked sidewalls in the first sidewall stacking bin 31 and can also convey and output the bottommost sidewall for feeding. The first sidewall stacking bin 31 includes a first side baffle component 34 (such as a side baffle, side baffle bar, etc., which can be located on the left and right sides and the output side, and can even be used for feeding). The sides are arranged in a stacking space (adjustable left, right, front, and back positions to meet different sidewall size requirements). A first feeding outlet 35 is provided between the bottom end of the first side baffle component 34 and the first feeding conveyor belt 32 for feeding the sidewall. A gap is set between the bottom end of the first side baffle component 34 on the output side and the first feeding conveyor belt 32 as the first feeding outlet 35. The position of the first side baffle component on the output side can be adjusted to change the size of the first feeding outlet 35. A pressure roller can also be added in the output direction to press down the sidewall for stable conveying. This feeding structure is suitable for sidewall conveying and can smoothly and stably feed sidewalls that are thicker in the middle and thinner on both sides. The conveying direction of the first feeding conveyor belt 32 can also be orthogonal to the conveying direction of the first sidewall conveyor belt 22. The conveying direction in the figure is longitudinal, which is reasonable and facilitates subsequent position adjustment to meet different specification requirements.

[0044] For example, the second sidewall feeding device 21 includes a second support frame, a second sidewall stacking bin, and a second feeding conveyor belt. The second feeding conveyor belt and the second sidewall stacking bin are mounted on the second support frame for installation and connection. The second feeding conveyor belt is positioned at the bottom of the second sidewall stacking bin. The second feeding conveyor belt can support the stacked sidewalls in the second sidewall stacking bin and can also convey and output the bottommost sidewall for feeding. The second sidewall stacking bin includes second side baffle components (such as side baffles, side baffles, etc.), which can be located on the left, right, and output sides, and can even be adjusted to the left, right, front, and back positions. To meet the requirements of different sidewall sizes, a stacking space is formed. A second feeding outlet 45 is provided between the bottom end of the second sidewall baffle 44 and the second feeding conveyor belt 42 for feeding the sidewall. A gap is set between the bottom end of the second sidewall baffle 44 on the output side and the second feeding conveyor belt 42 as the first feeding outlet 45. The position of the second sidewall baffle on the output side can be adjusted to change the size of the first feeding outlet 45. A pressure roller can also be added in the output direction to press down on the sidewall for stable conveying. This feeding structure is suitable for sidewall conveying and can smoothly and stably feed sidewalls that are thicker in the middle and thinner on both sides. The feeding direction of the second feeding conveyor belt can also be orthogonal to the conveying direction of the second sidewall conveyor belt 23. In the figure, the feeding direction is longitudinal, which is a reasonable structure and facilitates subsequent position adjustment to meet different specifications.

[0045] In addition, the first sidewall conveyor belt 22 is equipped with a first side pusher 51 and a first side guide 52. The first side pusher 51 and the first side guide 52 are set at the first delivery station 27. The first side pusher 51 can push the sidewall on the first sidewall conveyor belt 22 towards the first side guide 52 to correct the relative position of the sidewall, so that the delivered sidewall is in the designed position for easy transfer and accurate assembly with the face paper. The first side guide 52 and the first side pusher 51 are respectively set on the left and right sides of the first sidewall conveyor belt 22. The first sidewall conveyor belt 22, the first side pusher 51, and the first side guide 52 are connected to the first frame 53 for installation and connection.

[0046] The second sidewall conveyor belt 23 is equipped with a second side pusher 56 and a second side guide 57. The second side pusher 56 and the second side guide 57 are located at the second delivery station 29. The second side pusher 56 can push the sidewall on the second sidewall conveyor belt 23 towards the second side guide 57 to correct the relative position of the sidewall, so that the delivered sidewall is in the designed position for easy transfer and accurate assembly with the face paper. The second side guide 57 and the second side pusher 56 are respectively located on the left and right sides of the second sidewall conveyor belt 23. The second sidewall conveyor belt 23, the second side pusher 56, and the second side guide 57 are connected to the second frame 58 for installation and connection.

[0047] Further optimization is possible. The position of the first frame 53 can be adjusted along the feeding direction of the first side wall feeding device 20, and / or the position of the second frame 58 can be adjusted along the feeding direction of the second side wall feeding device 21. This position adjustment can accommodate different side wall sizes and different spacing between the two side walls (used for assembly and connection on the same sheet). Corresponding guide rails can be configured for position adjustment, and a lead screw and nut mechanism 60 can also be used for position adjustment. In the figure, the second frame 58 is positioned on guide rail 59 for adjustment, while the first frame 53 is fixed in position. Additionally, the first side wall feeding device 20 and the second side wall feeding device 21 can be adjusted along their feeding directions. Corresponding tracks 33 and 43 can be provided for them (along with their respective first and second support frames). After changes in side wall specifications, the feeding process will be more smoothly connected after position adjustment. In front of the feeding direction, i.e., in front of the first feeding conveyor belt 32 and the second feeding conveyor belt, there are blocking components (such as blocking plates) so that when the side wall is fed and conveyed out by the first feeding conveyor belt 32 and the second feeding conveyor belt, the blocking components can cooperate to block the side wall, so that the side wall can fall smoothly onto the corresponding first side wall conveyor belt 22 and the second side wall conveyor belt 23 below.

[0048] For additional optimization, the first sidewall conveyor belt 22 is equipped with a first drive motor 61, and the second sidewall conveyor belt 23 is equipped with a second drive motor 62, both of which can be servo motors, etc. A first photoelectric sensor 63 is also installed above the first sidewall conveyor belt 22, and a second photoelectric sensor 64 is also installed above the second sidewall conveyor belt 23. The first photoelectric sensor 63 is connected to the first drive motor 61 to coordinate motor operation, and the second photoelectric sensor 64 is connected to the second drive motor 62 to control motor operation. After receiving the position signal of the upper sidewall on the lower conveyor belt through the corresponding photoelectric sensor, the corresponding drive motor can continue to drive the corresponding sidewall conveyor belt to advance the sidewall forward by the set distance. This avoids the problem of inaccurate sidewall position during previous sidewall feeding and conveyor belt transport, ensuring that the corresponding sidewall is delivered to the first delivery station 27 and the second delivery station 29 at the designed position, resulting in more accurate relative positioning when subsequently transferred and assembled onto the face paper. The first photoelectric sensor 63 can be configured between the first input station 26 and the first delivery station 27, and the second photoelectric sensor 64 can be configured between the second input station 28 and the second delivery station 29.

[0049] A camera 65 (such as an industrial camera) is installed above the main conveyor belt 3 for detecting the relative position signal of the face paper. The camera 65 is connected to the transfer robot 18. The signal detected by the camera 65 can be used to control the movement of the transfer robot 18 so that the transfer robot 18 can adjust the relative position of the side wall during the transfer process, so that the side wall is aligned with the face paper according to the set position for assembly and connection. The camera 65 can be configured at the side wall assembly station 7 of the main conveyor belt 3 for more accurate results.
