Description

Technical Field

[0001] This invention relates to the field of edge banding machine technology, and in particular to a square edge banding production system and its square edge banding production method. Background Technology

[0002] The custom furniture industry is gradually moving towards standardization and large-scale production. A pressing need for large-scale custom furniture factories is to evolve from stand-alone models to automated production lines. Therefore, custom furniture manufacturers are integrating processes such as material cutting, edge banding, drilling, sorting, and packaging into a single, complete production line. Currently, in domestic and international edge banding and squaring production lines, under the two-machine connection production process, the first pass seals the long edge, and then the first pass's workpieces are rotated back for the second pass to seal the short edge. The transfer is time-consuming, and the machine parameters need to be switched and adjusted when switching between sealing long and short edges, resulting in low efficiency. Under the four-machine connection production process, the transfer process from sealing the long edge to sealing the short edge can be eliminated. However, when the speed of sealing the long edge is greater than that of sealing the short edge, when the length-to-width ratio of the workpiece is close to 1:1 at a certain time, the machine sealing the short edge will become congested, causing the machine sealing the long edge to stop, resulting in poor edge banding and failing to maximize production capacity. In addition, there are always production line stoppages or downtime due to malfunctions during the entire production process, causing the conveyor belt of the edge banding section to start and stop repeatedly. If a board stops at the glue application shaft position of the edge banding machine, the glue applied to the board is exposed to the air for a certain period of time, and after cooling, the edge banding tape is applied. This results in the scrapping of panels at the glue application shaft of the edge banding machine, requiring rework and re-processing, which greatly wastes material and labor costs. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing a square edge banding production system and its method. The system is ingeniously designed to prevent clogging, thereby improving production efficiency and avoiding downtime caused by board congestion. It features a reliable structure and strong operational stability. Furthermore, its square edge banding method solves the technical problem of board damage when the adhesive application shaft stops in the edge banding production chain, preventing boards from stopping at the adhesive application device and causing prolonged adhesive compression and exposure to air, which could lead to poor edge banding.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention provides a square edge banding production system, comprising a control chassis and a square edge banding production line connected to the control chassis via signals. The control chassis includes a programmable logic controller (PLC), a human-machine interface control unit (HMI control unit), a position sensor control unit, and a conveyor belt control unit. The HMI control unit, position sensor control unit, and conveyor belt control unit are respectively connected to the PLC via signals. The square edge banding production line includes a first conveyor table, a first long edge banding machine, a first discharge conveyor device, a first square banding device, a second long edge banding machine, a second discharge conveyor device, a board storage device, a reversing conveyor device, a second square banding device, a first short edge banding machine, a third discharge conveyor device, a third square banding device, a second short edge banding machine, and a fourth discharge conveyor device, arranged sequentially along the board processing direction.

[0006] The board storage device includes an upper board storage and conveying mechanism and a lower board storage and conveying mechanism. The second discharge conveying device is used to convey the board to the upper board storage and conveying mechanism or the lower board storage and conveying mechanism.

[0007] The reversing transmission device is used to receive the wooden boards conveyed by the upper storage board transmission mechanism or the lower storage board transmission mechanism and transfer them to the second standard device. The transmission direction of the reversing transmission device is perpendicular to the discharge direction of the storage board device.

[0008] The first long-side sealing machine, the second long-side sealing machine, the first short-side sealing machine, and the second short-side sealing machine are respectively connected to the position sensor control unit via signals; the first conveyor table, the first discharge conveying device, the first squaring device, the second discharge conveying device, the storage device, the reversing conveying device, the second squaring device, the third discharge conveying device, the third squaring device, and the fourth discharge conveying device are respectively connected to the conveyor belt control unit via signals;

[0009] The first long-side sealing machine includes a first gluing device and a first board position module. The first board position module is signal-connected to the position sensor control unit. When the control box receives a stop signal, the first board position module detects whether there is a board at the station of the first gluing device. If a board is detected at the station of the first gluing device, a signal is sent to the position sensor control unit. The programmable controller controls the conveyor belt control unit to continue working according to the position sensor control unit, and continues to transmit the board until the board at the station of the first gluing device is removed from the station of the first gluing device.

[0010] The first discharge conveying device includes a second conveying table, which is used to convey the sheet material discharged from the first long-side edge banding machine to the first squaring device, which is used to perform side-squaring processing on the sheet material.

[0011] The second discharge conveying device includes a third conveying platform, a fourth conveying platform, a fifth conveying platform, a sixth conveying platform, and a seventh conveying platform arranged sequentially along the board processing direction. The second discharge conveying device also includes a first lifting drive mechanism for driving the sixth conveying platform to rise and fall. The sixth conveying platform is located at the discharge end of the fifth conveying platform. The discharge end of the sixth conveying platform is respectively arranged corresponding to the inlet end of the seventh conveying platform and the inlet end of the lower board storage conveying mechanism. The discharge end of the seventh conveying platform is respectively arranged corresponding to the inlet end of the upper board storage conveying mechanism.

[0012] The lower-level storage board transfer mechanism includes an eighth and a tenth conveyor station arranged in sequence, and the upper-level storage board transfer mechanism includes a ninth and an eleventh conveyor station arranged in sequence. The discharge end of the seventh conveyor station is corresponding to the inlet end of the ninth conveyor station, and the discharge end of the sixth conveyor station is corresponding to the inlet ends of the seventh and eighth conveyor stations, respectively.

[0013] The reversing transmission device includes a twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, and nineteenth conveyor tables arranged sequentially. The reversing transmission device also includes a second lifting drive mechanism for driving the twelfth conveyor table to rise and fall. The inlet end of the twelfth conveyor table should be aligned with the outlet end of the upper storage plate transmission mechanism. The outlet end of the twelfth conveyor table should correspond to the inlet end of the thirteenth conveyor table. The outlet end of the nineteenth conveyor table should correspond to the inlet end of the second regulating device.

[0014] The third discharge conveying device includes a twentieth conveyor, the inlet end of which corresponds to the inlet end of the first short-side sealing machine, and the outlet end of which corresponds to the inlet end of the third squaring device.

[0015] The fourth discharge conveying device includes a twenty-first conveyor table, which is equipped with a steering mechanism.

[0016] The second long-side sealing machine includes a second gluing device and a second board position module. When the control box receives a stop signal, the second board position module detects whether there is a board at the station of the second gluing device. If a board is detected at the station of the second gluing device, the board is continued to be transferred until the board at the station of the second gluing device is removed from the station of the second gluing device.

[0017] The first short-side sealing machine includes a third gluing device and a third board position module. When the control box receives a stop signal, the third board position module detects whether there is a board at the station of the third gluing device. If a board is detected at the station of the third gluing device, the board is continued to be transferred until the board at the station of the third gluing device is removed from the station of the third gluing device.

[0018] The second short-side sealing machine includes a fourth gluing device and a fourth board position module. When the control box receives a stop signal, the fourth board position module detects whether there is a board at the station of the fourth gluing device. If a board is detected at the station of the fourth gluing device, the board is continued to be transferred until the board at the station of the fourth gluing device is removed from the station of the fourth gluing device.

[0019] This invention also provides a method for producing square edge banding based on the aforementioned square edge banding production system. The board material is fed and transported sequentially through a first conveyor table, a first long-side edge banding machine, a first discharge conveyor device, a first square device, a second long-side edge banding machine, a second discharge conveyor device, a board storage device, a reversing conveyor device, a second square device, a first short-side edge banding machine, a third discharge conveyor device, a third square device, a second short-side edge banding machine, and a fourth discharge conveyor device. When the control box receives a stop signal, if the board position module detects a board at the glue application station of the edge banding machine, it sends a signal to the position sensor control unit. The programmable controller, based on the position sensor control unit, controls the conveyor belt control unit to continue operating, continuing to transport the board until the board at the glue application station of the edge banding machine is removed from the glue application station.

[0020] The beneficial effects of this invention are:

[0021] This invention features an ingenious design. During operation, the sheet material is fed from the first conveyor table and sequentially passes through the first long-side edge banding machine, the first discharge conveyor device, the first squaring device, the second long-side edge banding machine, the second discharge conveyor device, the sheet storage device, the reversing conveyor device, the second squaring device, the first short-side edge banding machine, the third discharge conveyor device, the third squaring device, and the second short-side edge banding machine before being discharged through the fourth discharge conveyor device. The first and second long-side edge banding machines respectively band the two long sides of the sheet material, and the first and second short-side edge banding machines respectively band the two short sides. The first, second, and third squaring devices are used for side-squaring the sheet material. This invention also includes a sheet storage device, comprising an upper and lower sheet storage conveyor mechanism, utilizing these two layers for conveying the sheet material. This invention acts as a buffer, slowing down the speed at which boards are conveyed to the reversing transmission device and buffering the gap between adjacent boards, thus preventing blockages and improving production efficiency. It avoids downtime caused by board congestion, has a reliable structure, and strong operational stability. Furthermore, this invention can solve the problem of boards being damaged when they stop at the glue application shaft in the edge banding production chain. When the position sensor control unit records that the board is at the position of the glue application device controlled by the glue shaft control unit, the conveyor stops only after the board has passed the glue application device. When the position module records that the board is not at the position of the glue application device controlled by the glue shaft control unit, the conveyor stops directly. This eliminates the problem of prolonged glue compression and exposure to air when the board stops at the glue application device position, causing poor edge banding. The embodiments of this application can save on material and labor costs for rework and re-processing. Attached Figure Description

The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Embodiment 1 of this application provides a square edge banding production system, such as Figure 1-Figure 2As shown, it includes a control chassis and a squaring and edge banding production line connected to the control chassis via signals. The control chassis includes a programmable logic controller (PLC) 100, a human-machine interface control unit (HMI) 200, a position sensor control unit (PSU) 300, and a conveyor belt control unit (FTU) 400. The HMI 200, PSU 300, and FTU 400 are respectively connected to the PLC 100 via signals. The squaring and edge banding production line includes a first conveyor table 1, a first long-side edge banding machine 2, a first discharge conveyor device, a first squaring device 4, and a second long-side edge banding device, arranged sequentially along the board processing direction. Machine 5, second discharge conveying device, board storage device, reversing conveying device, second squaring device 23, first short edge banding machine 24, third discharge conveying device, third squaring device 26, second short edge banding machine 27, and fourth discharge conveying device; the board storage device includes an upper board storage conveying mechanism and a lower board storage conveying mechanism; the second discharge conveying device is used to convey boards to the upper board storage conveying mechanism or the lower board storage conveying mechanism; the reversing conveying device is used to receive the boards conveyed by the upper board storage conveying mechanism or the lower board storage conveying mechanism and transfer them to the second squaring device 23, and the reversing conveying... The transmission direction of the device is perpendicular to the discharge direction of the storage device; the first long-side sealing machine 2, the second long-side sealing machine 5, the first short-side sealing machine 24, and the second short-side sealing machine 27 are respectively connected to the position sensor control unit 300; the first conveyor table 1, the first discharge transmission device, the first squaring device 4, the second discharge transmission device, the storage device, the reversing transmission device, the second squaring device 23, the third discharge transmission device, the third squaring device 26, and the fourth discharge transmission device are respectively connected to the conveyor belt control unit 400; the first long-side sealing machine 2 includes a first gluing device. The first board position module is connected to the position sensor control unit 300 via signal. When the control box receives a stop signal, the first board position module detects whether there is a board at the station of the first gluing device 30. If a board is detected at the station of the first gluing device 30, a signal is sent to the position sensor control unit 300. The programmable controller 100 controls the conveyor belt control unit 400 to continue working according to the position sensor control unit 300, and continues to transport the board until the board at the station of the first gluing device 30 is removed from the station of the first gluing device 30.Specifically, the embodiments of this application have a novel structure and ingenious design. During operation, the sheet material is fed from the first conveyor table 1, and sequentially passes through the first long-side edge banding machine 2, the first discharge conveying device, the first squaring device 4, the second long-side edge banding machine 5, the second discharge conveying device, the sheet storage device, the reversing conveying device, the second squaring device 23, the first short-side edge banding machine 24, the third discharge conveying device, the third squaring device 26, the second short-side edge banding machine 27, and then is discharged through the fourth discharge conveying device. The first long-side edge banding machine 2 and the second long-side edge banding machine 5 respectively band the two long sides of the sheet material, while the first short-side edge banding machine... 24 and 27 respectively seal the two short edges of the board. The first squaring device 4, the second squaring device 23 and the third squaring device 26 are used to squaring the board sideways. The transmission direction of the reversing conveyor is perpendicular to the discharge direction of the board storage device, so that the board can be reversed when it is conveyed to the reversing conveyor. This makes it convenient for the subsequent second squaring device 23, first short edge sealing machine 24, second short edge sealing machine 27 and third squaring device 26 to directly process the two short edges of the board, which helps to simplify the turning process and improve processing efficiency. Among them, the first long edge sealing machine 2 and the second long edge sealing machine 2... Machine 5, the first short-side edge banding machine 24, the second short-side edge banding machine 27, the first squaring device 4, the second squaring device 23, and the third squaring device 26 are all conventional technologies and will not be described in detail here. This invention adds a board storage device, which includes an upper board storage and transmission mechanism and a lower board storage and transmission mechanism. The upper and lower layers are used to transport the boards separately, acting as a buffer to slow down the speed at which the boards are transported to the reversing transmission device and to buffer the spacing between adjacent boards, thus preventing blockages. This improves production efficiency, avoids downtime due to board congestion, and has a reliable structure and strong operational stability. (This application's embodiment...) This invention can be used to solve the problem of damaged panels when they stop at the glue application shaft in the edge banding production chain of the entire production line. When the position sensor control unit 300 records that the panel is at the station of the glue application device controlled by the glue shaft control unit 500, the conveyor will stop only after the panel has passed the glue application device. When the position module records that the panel is not at the station of the glue application device controlled by the glue shaft control unit 500, the conveyor will stop directly. This eliminates the situation where the glue is squeezed and exposed to air for a long time when the panel stops at the station of the glue application device, causing poor edge banding. The embodiments of this application can save the material and labor costs of re-filling and reprocessing.

[0030] In this embodiment of the application, the first discharge conveying device includes a second conveying table 3, which is used to convey the board material discharged from the first long edge sealing machine 2 to the first squaring device 4, which is used to perform side squaring processing on the board material.

[0031] In this embodiment, the second discharge conveying device includes a third conveyor 6, a fourth conveyor 7, a fifth conveyor 8, a sixth conveyor 9, and a seventh conveyor 10 arranged sequentially along the plate processing direction. The second discharge conveying device also includes a first lifting drive mechanism for driving the sixth conveyor 9 to rise and fall. The sixth conveyor 9 is located at the discharge end of the fifth conveyor 8. The discharge end of the sixth conveyor 9 is respectively arranged corresponding to the inlet end of the seventh conveyor 10 and the inlet end of the lower plate storage conveying mechanism. The discharge end of the seventh conveyor 10 is respectively arranged corresponding to the inlet end of the upper plate storage conveying mechanism. The lower plate storage conveying mechanism includes an eighth conveyor 11 and a tenth conveyor 12 arranged sequentially. The upper plate storage conveying mechanism includes a ninth conveyor 13 and an eleventh conveyor 14 arranged sequentially. The discharge end of the seventh conveyor 10 is respectively arranged corresponding to the inlet end of the ninth conveyor 13. The discharge end of the sixth conveyor 9 is respectively arranged corresponding to the inlet end of the seventh conveyor 10 and the inlet end of the eighth conveyor 11. Specifically, under the above configuration, when receiving material at the lower storage and transfer mechanism, the board material is sequentially transported from the third conveyor 6, the fourth conveyor 7, the fifth conveyor 8, and the sixth conveyor 9 to the lower storage and transfer mechanism; when receiving material at the upper storage and transfer mechanism, after the board material is transported from the fifth conveyor 8 to the sixth conveyor 9, the first lifting drive mechanism drives the sixth conveyor 9 to move upward, so that the sixth conveyor 9 can transport the board material to the seventh conveyor 10; the first lifting drive mechanism reciprocates to drive the sixth conveyor 9 to move up and down, thereby transporting the board material from the sixth conveyor 9 to the seventh conveyor 10.

[0032] In this embodiment, the reversing transmission device includes a twelfth conveyor 15, a thirteenth conveyor 16, a fourteenth conveyor 17, a fifteenth conveyor 18, a sixteenth conveyor 19, a seventeenth conveyor 20, an eighteenth conveyor 21, and a nineteenth conveyor 22 arranged sequentially. The reversing transmission device also includes a second lifting drive mechanism for driving the twelfth conveyor 15 to rise and fall. The inlet end of the twelfth conveyor 15 should be connected to the outlet end of the upper storage plate transmission mechanism. The outlet end of the twelfth conveyor 15 should be connected to the inlet end of the thirteenth conveyor 16. The outlet end of the nineteenth conveyor 22 should be connected to the inlet end of the second regulating device 23. Specifically, under the above configuration, the second lifting drive mechanism can drive the twelfth conveyor table 15 to move up and down, so that the twelfth conveyor table 15 can receive the board material sent out by the upper board storage and transfer mechanism. The transfer direction of the twelfth conveyor table 15 is perpendicular to the transfer direction of the upper board storage and transfer mechanism. The board material is transferred to the thirteenth conveyor table 16 by changing direction by 90° through the twelfth conveyor table 15, and then sequentially passes through the fourteenth conveyor table 17, the fifteenth conveyor table 18, the sixteenth conveyor table 19, the seventeenth conveyor table 20, the eighteenth conveyor table 21 and the nineteenth conveyor table 22 before entering the thirteenth conveyor table 16. In the second square device 23, the short side of the board is squared. Similarly, the board sent by the lower board storage and transmission mechanism is received on the fourteenth conveyor 17. The transmission direction of the fourteenth conveyor 17 is perpendicular to the transmission direction of the lower board storage and transmission mechanism. The board is transferred to the fifteenth conveyor 18 by changing direction by 90° through the fourteenth conveyor 17. After passing through the sixteenth conveyor 19, seventeenth conveyor 20, eighteenth conveyor 21 and nineteenth conveyor 22, it enters the second square device 23 to square the short side of the board.

[0033] In this embodiment, both the first conveyor 1 and the nineteenth conveyor 22 are equipped with barcode scanning devices to scan the barcodes of the boards to obtain board information, facilitating automated information recording and processing.

[0034] In this embodiment of the application, the third discharge conveying device includes a twentieth conveyor 25, the inlet end of the twentieth conveyor 25 is correspondingly arranged with the inlet end of the first short edge sealing machine 24, and the outlet end of the twentieth conveyor 25 is correspondingly arranged with the inlet end of the third squaring device 26.

[0035] In this embodiment, the fourth discharge conveying device includes a twenty-first conveyor table 28, which is equipped with a steering mechanism 29. Specifically, since the long side of the board is first processed by the first long-side sealing machine 2, the board is fed into the first conveyor table 1 along its long side. This allows the board to be fed into the first long-side sealing machine 2 along its length for edge sealing, reducing the need for turning the board and facilitating one-person operation for loading. Furthermore, the twenty-first conveyor table 28 is equipped with a steering mechanism 29, which facilitates reversing the board's direction, converting the short side to the long side for discharge. This allows the board to be discharged along its length, facilitating one-person operation for unloading. In other words, in this embodiment, only one person is needed for both board loading and unloading, which helps reduce labor costs and improve work efficiency.

[0036] In this embodiment, the first conveyor 1, the second conveyor 3, the third conveyor 6, the sixth conveyor 9, the tenth conveyor 12, the eleventh conveyor 14, the nineteenth conveyor 22, the twentieth conveyor 25, and the twenty-first conveyor 28 are all offset roller conveyor lines, which facilitate the offset transmission of the plate material to the side. This is a conventional technology and will not be described in detail here.

[0037] In this embodiment of the application, the sixth conveyor table and the eighth conveyor table are arc-shaped conveyor tables used to drive the plate to rotate 90°.

[0038] In this embodiment, the first long-side sealing machine 2 includes a first gluing device 30 and a first board position module. When the control box receives a stop signal, the first board position module detects whether there is a board at the station of the first gluing device 30. If a board is detected at the station of the first gluing device 30, the board continues to be transported until the board at the station of the first gluing device 30 is removed from the station of the first gluing device 30. The second long-side sealing machine 5 includes a second gluing device 31 and a second board position module. When the control box receives a stop signal, the second board position module detects whether there is a board at the station of the second gluing device 31. If a board is detected at the station of the second gluing device 31, the board continues to be transported until the board at the station of the second gluing device 31 is removed from the station of the second gluing device 31. The first short-side edge banding machine 24 includes a third gluing device 32 and a third board position module. When the control box receives a stop signal, the third board position module detects whether there is a board at the station of the third gluing device 32. If a board is detected at the station of the third gluing device 32, the board continues to be transported until the board at the station of the third gluing device 32 is removed from the station of the third gluing device 32. The second short-side edge banding machine 27 includes a fourth gluing device 33 and a fourth board position module. When the control box receives a stop signal, the fourth board position module detects whether there is a board at the station of the fourth gluing device 33. If a board is detected at the station of the fourth gluing device 33, the board continues to be transported until the board at the station of the fourth gluing device 33 is removed from the station of the fourth gluing device 33. Specifically, under the above settings, the first board position module, the second board position module, the third board position module, and the fourth board position module respectively detect whether there are boards at the workstations of the first gluing device 30, the second gluing device 31, the third gluing device 32, and the fourth gluing device 33. If there are, the boards continue to be conveyed forward until they leave the workstations of the first gluing device 30, the second gluing device 31, the third gluing device 32, and the fourth gluing device 33. This allows the board to pass through the gluing shaft of the gluing device before the standard edge banding production line is stopped, eliminating the situation where boards stop at the gluing point of the gluing device and causing defective products. This enables normal production, reduces downtime and defective products, and achieves rapid production reset of the production line, resulting in a reliable structure.

[0039] In this embodiment of the application, the control chassis also includes a glue shaft control unit 500 that is signal-connected to the programmable controller 100. The glue shaft control unit 500 is signal-connected to the first glue applicator 30, the second glue applicator 31, the third glue applicator 32 and the fourth glue applicator 33 respectively, and is used to control the start or stop of the first glue applicator 30, the second glue applicator 31, the third glue applicator 32 and the fourth glue applicator 33 respectively.

[0040] Example 2

[0041] In Embodiment 2 of this application, a method for producing square edge banding based on the aforementioned square edge banding production system is provided. The board material is fed and transported sequentially through a first conveyor table 1, a first long edge banding machine 2, a first discharge conveyor device, a first square device 4, a second long edge banding machine 5, a second discharge conveyor device, a board storage device, a reversing conveyor device, a second square device 23, a first short edge banding machine 24, a third discharge conveyor device, a third square device 26, a second short edge banding machine 27, and a fourth discharge conveyor device. When the control box receives a stop signal, if the board position module detects that there is a board at the glue application station of the edge banding machine, it sends a signal to the position sensor control unit 300. The programmable controller 100 controls the conveyor belt control unit 400 to continue working according to the position sensor control unit 300, continuing to transport the board until the board at the glue application station of the edge banding machine is removed from the glue application station of the edge banding machine. Specifically, the above method addresses the issue of damaged panels being stopped at the glue application shaft during the edge banding production chain. When the position sensor control unit 300 records that the panel is at the station of the glue application device controlled by the glue shaft control unit 500, the conveyor is stopped only after the panel has passed the glue application device. When the position module records that the panel is not at the station of the glue application device controlled by the glue shaft control unit 500, the conveyor is stopped directly. This eliminates the problem of poor edge banding caused by prolonged pressure and exposure to air when the panel stops at the glue application device station. This embodiment of the application can save on material and labor costs for re-filling and reprocessing.
