[0002] Customized panel furniture products include semi-finished products of various sizes. After the raw materials are cut into semi-finished products, large and small panels need to be separated because the edge banding machine cannot process large and small panels at the same time. After separation, the large and small panels are edge banded by large panel edge banding machine and narrow panel edge banding machine respectively.

With the assistance of the guide pressure roller or the pusher block of the feeding auxiliary guiding mechanism, this solution can easily, stably, and accurately feed both narrow, horizontally or vertically placed boards and ordinary large boards. This solution has a simple and compact structure, stable and reliable operation, and good edge banding quality.

[0004] Regarding the aforementioned technologies, the existing technologies have the following drawbacks: deviation is prone to occur during the sheet metal feeding process. Summary of the Invention

[0005] Therefore, it is necessary to provide an automatic feeding method for edge banding of sheet metal to solve the problem of deviation that easily occurs during the feeding process.

[0006] To achieve the above objectives, this application provides an automatic feeding method for sheet metal edge banding, comprising the following steps:

[0007] The PLC controller acquires the size information of the board;

[0008] The PLC controller controls the side pushing mechanism and the ejection mechanism according to the size information of the board. The side pushing mechanism presses the short side of the board against the edge banding machine's stop, and the ejection mechanism positions the long side of the board. The ejection mechanism moves along with the circulating chain block mechanism and drives the board forward along the edge banding direction.

[0009] Furthermore, the automatic feeding method for auxiliary edge banding of sheet metal is applied to an automatic feeding device for auxiliary edge banding of sheet metal. The automatic feeding device for auxiliary edge banding of sheet metal includes a feeding device body, which includes a circulating chain block mechanism, a guiding mechanism, a side pushing mechanism, a frame, a PLC controller, and an ejection mechanism.

[0010] The frame includes a fixed frame and a mounting frame. The fixed frame fixes the circulating chain block mechanism. The ejector mechanism is located on the circulating chain block mechanism. The guide mechanism, the side push mechanism, and the PLC controller are mounted on the mounting frame. The PLC controller is electrically driven connected to the circulating chain block mechanism, the guide mechanism, the side push mechanism, and the ejector mechanism.

[0011] Furthermore, a first conveyor line, a second conveyor line, and an edge banding machine are provided outside the automatic feeding device for edge banding of the sheet metal;

[0013] The edge banding machine is located at the rear end of the automatic feeding device for edge banding of the board, and is used to edge band the board coming from the automatic feeding device for edge banding of the board;

[0014] The second conveyor line is located at the rear end of the edge banding machine and is used to receive the board material from the edge banding machine;

[0015] The first conveyor line and the second conveyor line are respectively electrically driven connected to the PLC controller;

[0016] The host computer is communicatively connected to the PLC controller. The host computer is used to obtain the size information of the board input by the user and send it to the PLC controller.

[0017] Furthermore, it also includes the following steps:

[0018] The host computer obtains the size information of the board input by the user. The size information includes the length and width of the board. The size information of multiple boards forms a data queue. The data queue is arranged in order of reception time. The size information of newly received boards is added to the end of the data queue.

[0019] Furthermore, it also includes the following steps:

[0020] The host computer provides an interface for changing the speed of the first conveyor line. Users can adjust the speed of the first conveyor line conveying the plates to match the speed of the upstream equipment.

[0021] Furthermore, it also includes the following steps:

[0022] The host computer provides an interface for changing the speed of the second conveyor line. Users can adjust the speed of the second conveyor line to transport the plates so that the speed of the second conveyor line to transport the plates matches that of the downstream edge banding machine.

[0023] Furthermore, the circulating chain block mechanism has a notch, and the ejection mechanism includes a top-pile cylinder, which is installed in the notch and can protrude from the notch. The PLC controller is electrically driven connected to the top-pile cylinder.

[0024] Furthermore, the circulating chain block mechanism includes multiple sets of parallel circulating chain blocks, each circulating chain block having the notch, and the circulating chain block being connected to a drive servo motor. The end face of the fixed frame is provided with multiple sets of symmetrical supports, each support being fixedly connected to a rotating clamping plate. The circulating chain block is rotatably mounted on the rotating clamping plate. The drive servo motor is located at the side end of one set of circulating chain blocks. The circulating chain block is connected to two sets of sprockets, each sprocket being connected to a rotating rod. The output shaft of the drive servo motor is fixedly connected to one of the rotating rods.

[0025] Furthermore, it also includes the following steps:

[0026] If the size of the plate is smaller than the preset length, the side push mechanism that is closer to the plate will be used to shape the plate.

[0027] If the size of the plate is larger than the preset length, the side-pushing mechanism, which is farther away from the plate, will be used to shape the plate.

[0028] The above technical solution can automatically guide the board to the edge banding machine for edge banding, improving the accuracy and efficiency of edge banding. The PLC controller can control the action of the mechanism according to the size information of the board, which can adapt to the edge banding of boards of different sizes, improving the applicability of the device. In addition, the circulating chain block mechanism and the guiding mechanism can help the board to remain stable and avoid deviation, thus improving the quality of edge banding.

[0041] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0042] Please see Figures 1 to 4 This embodiment provides an automatic feeding device for edge banding of sheet metal, including a feeding device body 1. The feeding device body 1 includes a circulating chain block mechanism 3, a guiding mechanism 4, a side pushing mechanism 5, a frame 2, a PLC controller, and an ejection mechanism 9.

[0043] The frame 2 includes a fixed frame 22 and a mounting frame 21. The fixed frame 22 fixes the circulating chain block mechanism 3. The ejection mechanism 9 is located on the circulating chain block mechanism 3. The guide mechanism 4, the side push mechanism 5 and the PLC controller are mounted on the mounting frame 21. The PLC controller is electrically driven connected to the circulating chain block mechanism 3, the guide mechanism 4, the side push mechanism 5 and the ejection mechanism 9.

[0044] The PLC controller controls the side pushing mechanism 5 and the ejection mechanism 9 to operate based on the size information (length and width) of the board. The side pushing mechanism 5 presses the short side of the board against the edge banding machine's stop, and the ejection mechanism 9 positions the long side of the board and drives the board forward along the edge banding direction.

[0045] The above technical solution can automatically guide the board to the edge banding machine for edge banding, improving the accuracy and efficiency of edge banding. The PLC controller can control the action of the mechanism according to the size information of the board, which can adapt to the edge banding of boards of different sizes, improving the applicability of the device. In addition, the circulating chain block mechanism and the guiding mechanism can help the board to remain stable and avoid deviation, thus improving the quality of edge banding.

[0046] Please see Figure 4 In this embodiment, the circulating chain block mechanism 3 has a notch, and the ejection mechanism 9 includes a push-pile cylinder 91. The push-pile cylinder 91 is installed in the notch and can protrude from the notch. This design allows the ejection mechanism 9 to extend when needed to position and push the plate. The PLC controller is electrically driven connected to the push-pile cylinder 91 and is used to control the action of the push-pile cylinder 91. The control system identifies the size of the plate based on the queue data. If the size of the plate is larger than the set position, it is ejected by the push-pile cylinder 91 at the corresponding position to ensure that plates of different sizes can be transported normally.

[0047] Please see Figure 4 and Figure 5 In this embodiment, the circulating chain block mechanism 3 includes multiple sets of parallel circulating chain blocks 31. Each circulating chain block 31 has a notch. Each circulating chain block 31 is connected to a drive servo motor 6.

The circulating chain block 31 is rotatably mounted on the rotating clamp 32. The drive servo motor 6 is located at the side end of one set of circulating chain blocks 31. Each circulating chain block 31 is connected to two sets of sprockets. Each sprocket is connected to a rotating rod 61. The output shaft of the drive servo motor 6 is fixedly connected to one of the rotating rods 61.

Specifically, each circulating chain block 31 is provided with the notch, and each notch is provided with an ejector mechanism 9.

[0049] Please see Figures 1 to 3 In this embodiment, the guide mechanism 4 includes a first connecting frame 41, which is connected to the side end of the mounting frame 21;

[0050] The side-pushing mechanism 5 includes a second connecting frame 51 and a side-pushing frame 53; the second connecting frame 51 is connected to the side end of the mounting frame 21 through a movable component, the second connecting frame 51 is provided with a liftable side-pushing frame 53, both the side-pushing frame 53 and the first connecting frame 41 are provided with telescopic locking components, and the side plate of the side-pushing frame 53 protrudes higher than its corresponding telescopic locking component.

[0051] Please see Figure 6 In this embodiment, the telescopic locking assembly includes an adjusting cylinder 7, which is fixed to the end face of the first connecting frame 41 or the side push frame 53. The output shaft of the adjusting cylinder 7 is connected to a movable plate 71, which is connected to multiple mounting clamps 73. Guide wheels 75 are mounted on the mounting clamps 73. The side plate of the side push frame 53 protrudes and is positioned higher than the guide wheels 75. Multiple sets of telescopic buffers 74 are provided between the movable plate 71 and the mounting clamps 73 for the vertical movement of the guide wheels 75.

[0052] Please see Figure 6 In this embodiment, the movable plate 71 is provided with symmetrical limiting rods 72, and the first connecting frame 41 and the side push frame 53 are both provided with symmetrical sliding holes, and the limiting rods 72 move up and down in the sliding holes.

[0053] Please see Figure 8 , Figure 9 and Figure 10 In this embodiment, the second connecting frame 51 is provided with multiple sets of movable clamps 511 and an adjustment servo motor 8. The adjustment servo motor 8 is connected to an adjustment gear 81. The adjustment gear 81 and the movable clamps 511 are on the same end face.

The movable clamps 511 are slidably connected to the sliding teeth 211, and the adjustment gear 81 meshes with the rack 212.

[0054] Please see Figure 8 , Figure 9 and Figure 10 In this embodiment, the second connecting frame 51 is provided with multiple sets of lifting clamps 512, the side push frame 53 is provided with multiple sets of lifting teeth 531, the lifting clamps 512 are slidably connected to the lifting teeth 531, the second connecting frame 51 is provided with an adjusting cylinder 7, and the output shaft of the adjusting cylinder 7 is fixedly connected to the side push frame 53.

[0055] This application enables automatic wire sealing of short edges on small boards, saving labor, improving efficiency, and enhancing product quality stability.

[0056] This embodiment also provides an automatic feeding method for edge banding of sheet metal, including the following steps:

[0057] The PLC controller acquires the size information of the board;

[0058] The PLC controller controls the side pushing mechanism and the ejection mechanism according to the size information of the board. The side pushing mechanism presses the short side of the board against the edge banding machine's stop, and the ejection mechanism positions the long side of the board. The ejection mechanism moves along with the circulating chain block mechanism and drives the board forward along the edge banding direction.

[0059] Specifically, the preceding process system sends the dimensions of the small board to the PLC controller of this device. The PLC controller allows the small board to enter the feeding device body 1. The small board contacts the circulating chain block 31, and the drive servo motor 6 is started to drive the rotating rod 61 to rotate. The rotating rod 61 drives the circulating chain block 31 to rotate through the set sprocket, thus automatically feeding the small board. The adjustment servo motor 8 is started to drive the adjustment gear 81 to rotate. The adjustment gear 81 meshes with the rack 212 and moves on the rack 212. At the same time, the moving clamp 511 moves on the sliding gear 211. The structure is as follows. Figure 7 As shown, when the small plate is moved to a suitable position, the adjusting cylinders 7 on the first connecting frame 41 and the side push frame 53 work simultaneously to push the movable plate 71 to move. When the movable plate 71 moves, the limiting rod 72 moves in the sliding hole to limit the movable plate 71. The movable plate 71 drives the telescopic buffer 74, the mounting clamp 73 and the guide wheel 75 to move. The small plate moves to the lower end of the guide wheel 75 and contacts the guide wheel 75 in the circulating chain block 31. The guide wheel 75 and the side push frame 53 position, lock and transport the small plate.

[0060] When encountering plates of varying thicknesses, the telescopic buffer 74 retracts, causing the guide wheel 75 and the mounting clip to move, thus improving the adaptability.

[0061] The side pusher 53 is pushed by the lifting cylinder 52, and the lifting clamp 512 moves on the lifting tooth 531, thereby realizing the height adjustment of the side pusher 53, which can ensure that the side pusher 53 can be adapted to small plates of different thicknesses.

[0062] The host computer sends the board size information to the PLC controller, and the PLC controller allows feeding.

[0063] The first conveyor line feeds the plate into the circulating chain block mechanism. The PLC controls the side pushing mechanism and the ejection mechanism on the circulating chain block to move according to the length and width of the plate. After the ejection mechanism moves, the circulating chain block mechanism drives the plate to move.

[0064] The ejection mechanism on the circulating chain block positions the plate from the long side. The PLC controls the side push mechanism to push the plate from the length direction according to the plate size. The two side pushers can switch freely according to the plate length. After the side pushers bring the short side of the plate close to the edge banding machine, the circulating chain block drives the ejection mechanism, and the ejection mechanism drives the plate forward along the edge banding direction.

[0065] After the sheet enters the edge banding machine, the side pusher and ejection mechanism are automatically retracted, completing the automatic feeding of the sheet.

[0066] Please see Figures 1 to 11 This embodiment also provides a panel edge banding device, including a panel edge banding auxiliary automatic feeding device, a first conveyor line 10, a second conveyor line 11, an edge banding machine 12, and a host computer;

[0067] The automatic feeding device for edge banding of the sheet metal is the automatic feeding device for edge banding of the sheet metal described in any of the above embodiments;

[0068] The first conveyor line 10 is located at the front end of the automatic feeding device for edge banding of the board, and is used to convey the board to the automatic feeding device for edge banding of the board.

[0069] The edge banding machine 12 is located at the rear end of the automatic feeding device for edge banding of the board, and is used to edge band the board coming from the automatic feeding device for edge banding of the board;

[0070] The second conveyor line 11 is located at the rear end of the edge banding machine 12 and is used to receive the board material from the edge banding machine 12;

[0071] The first conveyor line 10 and the second conveyor line 11 are electrically driven connected to the PLC controller, respectively.

[0072] The host computer is communicatively connected to the PLC controller. The host computer is used to obtain the size information of the board input by the user and send it to the PLC controller.

[0073] In this embodiment, to accommodate the shaping requirements of different boards, the host computer enables a board length writing function. Data can be obtained through communication with an external central control system or manually modified on a touchscreen. Since new boards continuously enter the first conveyor line during operation, and the first conveyor line sends boards in while the second conveyor line is on standby, to ensure accurate longitudinal shaping of the boards within the equipment, the host computer forms a data queue with the acquired dimensions of multiple boards during operation. This dimension information includes the board's length and width. The data queue is arranged according to the receiving time, with newly received board dimension information added to the end of the queue. Simultaneously, the current data queue content is displayed on the touchscreen, and the function to modify data is enabled for real-time monitoring and handling of abnormal situations. In this way, the board data is precisely sorted in the control system, ensuring accurate shaping and conveying of the boards.

[0074] In this embodiment, an edge banding machine is also provided at the rear end of the second conveyor line. The first conveyor line delivers the sheet to the edge banding machine located at the rear end of the first conveyor line, and the second conveyor line delivers the sheet to the edge banding machine located at the rear end of the second conveyor line. When the second conveyor line delivers the shaped sheet to the edge banding machine located at the rear end of the second conveyor line, the corresponding sheet size information is removed from the data queue.

[0075] In this embodiment, both the first and second conveyor lines are conveyor belts. The conveyor belts are connected in a closed loop and tensioned by a tensioning device. Driven by a transport servo motor, the conveyor belts operate continuously due to the friction between them and the drive rollers, thereby transporting the cargo from the loading end to the unloading end. In some embodiments, both the first and second conveyor lines are conveyor rollers.

[0076] In this embodiment, to achieve speed synchronization with upstream and downstream equipment, the host computer provides a speed adjustment interface for the first and second conveyor lines. The speed of the first conveyor line can be adjusted to match the upstream equipment, enabling synchronized board feeding; the speed of the second conveyor line can be adjusted to match the downstream edge banding machine, enabling synchronized board output. The board feeding and output actions are executed independently without interference, improving efficiency and resolving the issue of inconsistent speeds between upstream and downstream equipment.

[0077] To improve the forming efficiency of the sheet metal at the longitudinal forming device, the device employs two pusher mechanisms. The PLC controller identifies the sheet metal size based on the data queue sent from the host computer. If the sheet metal size is smaller than the preset length, a short-distance pusher mechanism is activated for forming; if the sheet metal size is larger than the preset length, a long-distance pusher mechanism is activated. Simultaneously, a position correction parameter modification interface is provided on the touchscreen. By modifying the correction parameters, the positions of the two pusher mechanisms can be adjusted for secondary adjustments to the forming effect. Furthermore, an alarm is triggered when the input data exceeds the device's alarm limit to prevent equipment collisions caused by misoperation.

[0078] The transport servo motor can synchronously adjust its speed based on the servo feedback distance when transporting the board, enabling multi-speed transport of the board. This improves efficiency and ensures a balanced starting speed on the board, effectively preventing the board from tilting.

[0079] This device replaces manual operation and enables on-line processing of small panels, improving efficiency. The ejector mechanism positions the long side of the panel, with the positioning surface perpendicular to the edge-sealing direction. After pre-milling by the edge-sealing machine, the perpendicularity of adjacent sides of the small panel is ensured, improving the product quality that was previously unstable due to manual feeding. The PLC controller, side-pushing mechanism, circulating chain block mechanism, and ejector mechanism work together to complete the ejection positioning, conveying, and side-pushing of the entire device, ultimately achieving labor savings and automatic edge-sealing of small panels on the line.

[0080] This device is particularly suitable for small plates.
