Description

Technical Field

[0001] This invention relates to the field of woodworking machinery technology, and in particular to a control system and control method for a short-side feeding pusher device. Background Technology

[0002] In the furniture customization industry, with the increasing demand for personalization and customization from consumers, the processing demand for short-edge panels has also increased significantly. These panels are typically long and narrow, and the edge banding process is particularly complex due to the short-edge feeding design of the edge banding machine. In traditional processing methods, the sides of the panels are usually pushed into the edge banding machine by a pusher mechanism, but this method has obvious drawbacks when processing narrow and long panels: the pushing process easily causes the panels to bend and deform, affecting the quality and aesthetics of the final product.

[0003] Furthermore, the varying lengths and widths of boards in each batch pose a significant challenge to automated processing. Currently, to ensure reliable positioning of parts during feeding, most furniture factories in China still rely on manual feeding. This method is not only inefficient but also makes it difficult to implement assembly line production, severely restricting the improvement of production efficiency and capacity.

[0004] Given the current situation, the custom furniture industry urgently needs an automated processing solution that can effectively handle narrow and long boards, solve the problem of transport transition when sealing short edges, and adapt to boards of different sizes. This solution should significantly improve production efficiency, reduce labor costs, and simultaneously ensure the quality and precision of processed parts to meet market demand for high-quality, personalized furniture products. Summary of the Invention

[0005] This invention addresses the problems of existing technologies by providing a control system and control method for a short-side feeding pusher device. By integrating a belt conveyor mechanism control unit, a conveyor table left and right pulling mechanism control unit, a pusher plate alignment mechanism control unit, a human-machine interface unit, and a CPU control unit, it achieves automated control of the entire process of plate conveying, position changing, and position correction. This improves the efficiency and accuracy of plate conveying, reduces manual intervention, lowers production costs, and enhances the stability and reliability of the equipment.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a control system for a short-side feeding pusher device. The short-side feeding pusher device includes a belt conveyor mechanism, a conveyor table left and right pulling mechanism, and a pusher alignment mechanism arranged sequentially along the board conveying direction. The board enters the belt conveyor mechanism from the tail of a first automatic edge banding machine. Then, the board is conveyed to a different position by the conveyor table left and right pulling mechanism, and then aligned by the pusher alignment mechanism before being sent to a second automatic edge banding machine. The control system includes a belt conveyor mechanism control unit, a conveyor table left and right pulling mechanism control unit, a pusher alignment mechanism control unit, a human-machine interface unit, and a CPU control unit. The belt conveyor mechanism, the conveyor table left and right pulling mechanism, and the pusher alignment mechanism are respectively signal-connected to the belt conveyor mechanism control unit, the conveyor table left and right pulling mechanism control unit, and the pusher alignment mechanism control unit. The belt conveyor mechanism control unit, the conveyor table left and right pulling mechanism control unit, the pusher alignment mechanism control unit, and the human-machine interface unit are respectively signal-connected to the CPU control unit.

[0008] The belt conveyor control unit includes a belt position sensor switch, a belt frequency converter, and a belt motor. The belt conveyor control unit is used to control the belt conveyor to convey the sheet metal.

[0009] The control unit of the left and right material pulling mechanism of the conveyor table is used to drive the left and right material pulling mechanism of the conveyor table to change the conveying position of the plate, and quickly transport the processed plate from the discharge position of the belt conveyor mechanism to the feeding position of the pusher plate feeding mechanism.

[0010] The pusher-aligning mechanism control unit includes a hook positioning mechanism control unit, an alignment mechanism control unit, and a conveying mechanism control unit;

[0011] The hook positioning mechanism control unit includes a hook sensing component, a top hook driving component, and a hook resetting driving component. The hook sensing component is used to sense the position of the hook and the plate. The top hook driving component controls the hook to extend based on the position of the hook and the plate sensed by the hook sensing component. The hook resetting driving component controls the hook to retract and return to its original position based on the position of the hook sensed by the hook sensing component (the origin position switch and the rotary encoder calculate the hook's running position).

[0012] The plate alignment mechanism control unit is used to align the plates on the conveying mechanism in two directions;

[0013] The conveying mechanism control unit includes a drive frequency converter, a drive motor, and a rotary encoder; the control signal of the drive frequency converter and the rotary encoder are respectively connected to the CPU control unit signal; the output terminal of the drive frequency converter is electrically connected to the input terminal of the drive motor; the drive motor is used to drive the guide chain of the conveying mechanism to rotate.

[0014] The belt position sensor switch, belt frequency converter and belt motor are each provided in two units; the belt conveyor mechanism is provided with two belt conveyor groups, and each belt conveyor group is provided with a belt position sensor switch, belt frequency converter and belt motor. The output end of the belt frequency converter is connected to the input end of the belt motor, and the output end of the belt motor is used to drive the belt conveyor group to work.

[0015] The control unit of the left and right material pulling mechanism of the conveyor table includes a plate length sensing switch group, a plate position sensing switch group, a long and short plate sensing switch, a baffle solenoid valve, a roller motor frequency converter, a first lifting belt frequency converter, a second lifting belt frequency converter, a first lifting belt solenoid valve and a second lifting belt solenoid valve.

[0016] The left and right material pulling mechanism of the conveyor table includes a roller conveyor group, a first lifting belt group and a second lifting belt group; the conveying direction of the first lifting belt group and the conveying direction of the second lifting belt group are at 90 degrees to the conveying direction of the roller conveyor group; the frequency converter and the solenoid valve of the first lifting belt are respectively set to correspond to the first lifting belt group; the frequency converter and the solenoid valve of the second lifting belt are respectively set to correspond to the second lifting belt group.

[0017] In standby mode, the first and second lifting belt groups are in the rising position. When the plate is conveyed to the edge of the roller conveyor group, the plate arrival sensing switch group is activated, and the first and second lifting belt solenoid valves are de-energized. The first and second lifting belt groups descend, and the plate falls onto the continuously rotating roller conveyor group, where it moves on the rollers.

[0018] When both the board position sensing switch group and the long / short board sensing switch detect a signal, it is determined to be a long board, and the first lifting belt group and the second lifting belt group work up and down simultaneously.

[0019] When the board position sensing switch group detects a signal and the long / short board sensing switch does not detect a signal, it is determined to be a short board. The board moves on the roller of the roller conveyor group. When it is a short board, the tail of the board is disengaged from the long / short board sensing switch, and the second lifting belt solenoid valve will be energized to rise so as to pick up the next board.

[0020] The sheet moves on the roller conveyor assembly. When the head of the sheet touches the sheet length sensing switch assembly, the CPU control unit controls the roller frequency converter to decelerate, and the sheet continues to move after deceleration. When it touches the sheet position sensing switch assembly, the roller frequency converter stops, the roller motor stops, and the sheet stops moving.

[0021] When the drum motor stops and there is a delay, the first lifting belt solenoid valve is energized and rises again. The second lifting belt solenoid valve rises again depending on the length of the board. After the baffle is corrected, the baffle solenoid valve is de-energized and rises to release the board, sending the board out of this position. When the tail of the board is disengaged from the board position induction switch group, the baffle solenoid valve is energized and the baffle is reset.

[0022] After the program starts, the roller inverter, the first lifting belt inverter, and the second lifting belt inverter start sequentially with a delay; after the program starts, the first lifting belt solenoid valve and the second lifting belt solenoid valve are energized and rise, and the baffle solenoid valve is energized and descends; waiting for the board to arrive.

[0023] The plate length sensing switch group includes multiple plate length sensing switches.

[0024] The board position sensing switch group includes multiple board position sensing switches.

[0025] The hook sensing component includes a first origin sensing switch, a first hook sensing switch, and a second hook sensing switch. As the board moves forward continuously, the tail of the board disengages from the first hook sensing switch until the second hook sensing switch touches the hook head. At this point, the top hook driving component causes the hook head to extend. As the board moves forward continuously, the tail of the board disengages from the first origin sensing switch. The rotary encoder calculates the board's running position. When the tail of the board reaches a preset position, the hook head reset driving component activates, retracting the originally extended hook head back to its original position.

[0026] The top hook drive assembly includes multiple top hook solenoid valves; the hook reset drive assembly includes multiple hook reset solenoid valves.

[0027] The plate alignment mechanism control unit includes a plate alignment position sensor switch, a baffle disengagement sensor switch, a bracket upper position sensor switch, a baffle middle position sensor switch, an over-thickness protection switch, a deceleration sensor switch, a plate alignment Z-axis servo driver, a plate alignment rotation servo driver, a baffle solenoid valve at the plate alignment position, and a bracket drive assembly.

[0028] The sheet material moves forward on the conveyor mechanism. When the sheet material encounters the baffle at the alignment point, it stops moving. After the sheet material encounters the baffle, the alignment point induction switch is triggered. The bracket drive assembly drives the bracket to rise to the correct position, triggering the upper bracket induction switch. The alignment Z-axis servo drive drives the rotating rubber wheel to descend to the sheet thickness position, so that the upper rubber wheel of the alignment servo touches the sheet surface. The alignment rotation servo drive drives the rotating rubber wheel to rub against the sheet surface, causing the sheet material to move towards the baffle direction, correcting the lateral (relative to the feeding direction) position of the sheet material. After the correction time is up, the alignment Z-axis servo drive drives it to rise, and the sheet material waits on the bracket for the hook to come over.

[0029] The hook moves forward and touches the side of the tail of the board, pushing the board forward. The front of the board presses against the baffle at the edge of the board. Because the baffle is perpendicular to the hook and parallel to the stop, the longitudinal position of the board (relative to the feeding direction) can be corrected by the pressing. The position of the baffle changes and touches the baffle center position induction switch. The baffle is de-energized and rises quickly to release the board. The hook continues to push the board forward. When the tail of the board leaves the baffle and the induction switch, the bracket drive assembly is de-energized, the bracket descends, and the board continues to move forward and enter the edge banding machine.

[0030] When the hook head descends rapidly at the end of the guide rail, the tail plate senses the deceleration sensor switch, which drives the drive inverter to decelerate immediately via the CPU control unit.

[0031] The bracket drive assembly includes multiple bracket solenoid valves.

[0032] This invention provides a control method for a short-side feed pusher device, which includes the following steps:

[0033] Step S1: After the program starts, the two belt frequency converters start sequentially with a delay, and the two belt conveyor groups start accordingly.

[0034] Step S2: When the first and second lifting belt groups are in the rising position, and the plate is conveyed to the edge position of the roller conveyor group, the plate arrival sensing switch group is activated, and the first and second lifting belt solenoid valves are de-energized; the first and second lifting belt groups descend, and the plate falls onto the continuously rotating roller conveyor group, and the plate moves on the rollers of the roller conveyor group.

[0035] When both the board position sensing switch group and the long / short board sensing switch detect a signal, it is determined to be a long board, and the first lifting belt group and the second lifting belt group work up and down simultaneously.

[0036] When the board position sensing switch group detects a signal, but the long / short board sensing switch does not, it is determined to be a short board. The board moves on the rollers of the roller conveyor group. When it is a short board, the tail of the board disengages from the long / short board sensing switch, and the second lifting belt solenoid valve is energized and rises to receive the next board. When the board moves on the roller conveyor group, the head of the board touches the board length sensing switch group. The CPU control unit controls the roller frequency converter to decelerate, and the board continues to move after deceleration. When it touches the board position sensing switch group, the roller frequency converter stops, the roller motor stops, and the board stops moving.

[0037] When the drum motor stops and there is a delay, the first lifting belt solenoid valve is energized and rises again. The second lifting belt solenoid valve rises again depending on the length of the board. After the baffle is corrected, the baffle solenoid valve is de-energized and rises to release the board, sending the board out of this position. When the tail of the board is disengaged from the board position induction switch group, the baffle solenoid valve is energized and the baffle is reset.

[0038] After the program starts, the drum inverter, the first lifting belt inverter, and the second lifting belt inverter start sequentially with a delay; after the program starts, the first lifting belt solenoid valve and the second lifting belt solenoid valve are energized and rise, and the baffle solenoid valve is energized and descends; waiting for the board to arrive;

[0039] Step S3: Drive the motor to rotate the guide rail chain continuously, thus moving the plate forward;

[0040] Step S4: The tail of the board disengages from the first hook head sensor switch, the second hook head sensor switch touches the hook head, and the top hook head drive assembly drives the hook head to extend.

[0041] Step S5: As the plate moves forward continuously, the tail of the plate disengages from the first origin induction switch. The rotary encoder calculates the running position of the plate. When the tail of the plate reaches the preset position, the hook head reset drive component is activated to retract the originally extended hook head back to its original position.

[0042] Step S6: The sheet moves forward on the conveying mechanism. When the sheet touches the baffle at the alignment point, it stops moving. After the sheet touches the baffle at the alignment point, the alignment point sensing switch is triggered, and the bracket drive assembly drives the bracket to rise.

[0043] Step S7: After the bracket rises to the position, the upper position sensor switch of the bracket is triggered. The Z-axis servo driver of the alignment plate drives the rotating rubber wheel to descend to the plate thickness position, so that the upper rubber wheel of the alignment plate servo touches the plate surface. The rotation servo driver of the alignment plate drives the rotating rubber wheel to rub against the plate surface, causing the plate to move towards the stop direction, and corrects the lateral (relative to the feeding direction) position of the plate.

[0044] Step S8: After the calibration time is up, the Z-axis servo drive of the plate is driven to rise, and the plate waits on the bracket for the hook to come over.

[0045] Step S9: The hook moves forward and touches the side of the tail of the plate, pushing the plate forward. The front of the plate is pressed against the baffle at the plate level. Because the baffle is perpendicular to the hook and parallel to the stop, the longitudinal position of the plate (relative to the feeding direction) can be corrected by the pressing. The position of the baffle changes and touches the baffle center position sensor switch. The baffle is de-energized and rises quickly to release the plate. The hook continues to push the plate forward.

[0046] Step S10: When the tail of the board disengages from the baffle and the induction switch, the bracket drive assembly is de-energized, the bracket descends, and the board continues to move forward into the edge banding machine.

[0047] Step S11: The rotary encoder counts to obtain the hook head reset distance;

[0048] Step S12: When the hook head is descending rapidly at the end of the guide rail, the tail plate senses the deceleration sensor switch, and the CPU control unit drives the drive frequency converter to decelerate immediately.

[0049] Step S13: When the deceleration time reaches the preset time, the speed recovers and the hook reaches the preset reset position. The hook reset drive component is activated to retract the originally extended hook back to its original position.

[0050] The beneficial effects of this invention are:

[0062] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. 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.

[0063] A control system for a short-side feed pusher device, such as Figures 1 to 10 As shown, the short-side feeding pusher device includes a belt conveyor mechanism, a conveyor table left and right pulling mechanism, and a pusher alignment mechanism arranged sequentially along the board conveying direction. The board enters the belt conveyor mechanism from the tail of the first automatic edge banding machine, and then the board is conveyed to the second automatic edge banding machine after being corrected by the conveyor table left and right pulling mechanism. The pusher alignment mechanism includes a frame, a hook positioning mechanism, an alignment mechanism, and a conveying mechanism. The conveying mechanism and the alignment mechanism are respectively mounted on the frame. The conveying mechanism includes multiple guide rail chains driven by the same drive shaft. A bracket is movably arranged on one side of each guide rail chain. The hook positioning mechanism is arranged on the guide rail chain. The alignment mechanism includes a baffle and a rotating rubber wheel arranged on one side of the baffle.

[0064] The control system includes a belt conveyor mechanism control unit, a conveyor table left and right pulling mechanism control unit, a pusher plate alignment mechanism control unit, a human-machine interface unit, and a CPU control unit. The belt conveyor mechanism, the conveyor table left and right pulling mechanism, and the pusher plate alignment mechanism are respectively signal-connected to the belt conveyor mechanism control unit, the conveyor table left and right pulling mechanism control unit, and the pusher plate alignment mechanism control unit. The belt conveyor mechanism control unit, the conveyor table left and right pulling mechanism control unit, the pusher plate alignment mechanism control unit, and the human-machine interface unit are respectively signal-connected to the CPU control unit.

[0065] The belt conveyor control unit includes a belt position sensor switch, a belt frequency converter, and a belt motor. The belt conveyor control unit is used to control the belt conveyor to convey the sheet metal.

[0066] The control unit of the left and right material pulling mechanism of the conveyor table is used to drive the left and right material pulling mechanism of the conveyor table to change the conveying position of the plate, and to transport the processed plate from the discharge position of the belt conveyor mechanism to the feeding position of the pusher plate feeding mechanism.

[0067] The pusher-aligning mechanism control unit includes a hook positioning mechanism control unit, an alignment mechanism control unit, and a conveying mechanism control unit;

[0068] The hook positioning mechanism control unit includes a hook sensing component, a top hook driving component, and a hook resetting driving component. The hook sensing component is used to sense the position of the hook and the plate. The top hook driving component controls the hook to extend based on the position of the hook and the plate sensed by the hook sensing component. The hook resetting driving component controls the hook to retract and return to its original position based on the position of the hook sensed by the hook sensing component (the hook running position is calculated by the origin position switch and the rotary encoder).

[0069] The plate alignment mechanism control unit is used to align the plates on the conveying mechanism in two directions;

[0070] The conveying mechanism control unit includes a drive frequency converter, a drive motor, and a rotary encoder; the control signal of the drive frequency converter and the rotary encoder are respectively connected to the CPU control unit signal; the output terminal of the drive frequency converter is electrically connected to the input terminal of the drive motor; the drive motor is used to drive the guide chain of the conveying mechanism to rotate.

[0071] Specifically, the control system of the short-side feeding pusher device in this application embodiment integrates a belt conveyor mechanism control unit, a conveyor table left and right pulling mechanism control unit, a pusher plate alignment mechanism control unit, a human-machine interface unit, and a CPU control unit, achieving automated control of the entire process of plate conveying, position changing, and position correction. This invention improves the efficiency and accuracy of plate conveying, reduces manual intervention, lowers production costs, and enhances the stability and reliability of the equipment.

[0072] In this embodiment, two belt position sensing switches, two belt frequency converters, and two belt motors are provided; the belt conveyor mechanism is provided with two belt conveyor groups, and each belt conveyor group is provided with a belt position sensing switch, a belt frequency converter, and a belt motor. The output terminal of the belt frequency converter is connected to the input terminal of the belt motor, and the output terminal of the belt motor is used to drive the belt conveyor group to work.

[0073] After the system in this embodiment starts, the CPU control unit receives the parameters set by the user through the human-machine dialogue unit, and performs position calculations for each control unit based on these parameters. The Z-axis servo of the board alignment mechanism control unit automatically rises to the waiting position according to the board thickness, and the board alignment rotation servo also rises and starts rotating. The belt conveyor mechanism control unit and the left and right material pulling mechanism control unit of the conveyor table control the corresponding motors and frequency converters to start sequentially with a delay, preparing for the conveying of the board. The board enters the belt conveyor mechanism from the tail of the first automatic edge banding machine. The belt conveyor mechanism control unit detects the position of the board through the belt position sensor switch and controls the belt motor and frequency converter to adjust the conveying speed, so as to smoothly convey the board to the left and right material pulling mechanism of the conveyor table. The left and right material pulling mechanism control unit of the conveyor table controls the operation of the lifting belt solenoid valve and the roller motor frequency converter according to the length of the board and the signal of the sensor switch, changes the conveying position of the board, and smoothly conveys the board to the pusher board alignment mechanism position. The board enters the pusher board alignment mechanism. After the mechanism is completed, the conveyor control unit first controls the drive motor and frequency converter to make the guide chain move the plate forward. When the plate hits the baffle at the alignment point, the alignment mechanism control unit detects the position of the plate through the position sensor switch and controls the bracket solenoid valve to rise, lifting the plate. Then, the alignment Z-axis servo descends to the plate thickness position, and the alignment rotation servo continues to rotate, correcting the lateral (relative to the feeding direction) position of the plate by rubbing the rotating rubber wheel against the plate surface. After correction, the alignment Z-axis servo rises, and the plate waits on the bracket for the hook to come. Plate pushing and entering the next process: The hook positioning mechanism control unit controls the top hook drive component to extend the hook according to the signal of the hook sensing component, pushing the plate forward. When the front of the plate presses against the baffle at the alignment point and triggers the baffle center position sensor switch, the baffle at the alignment point is de-energized and released, and the hook continues to push the plate forward. When the tail of the plate disengages from the baffle and disengages from the sensor switch, the bracket solenoid valve is de-energized, the bracket descends, and the hook continues to push the plate into the second automatic edge banding machine.

[0074] Throughout the entire operation, the CPU control unit monitors the system's operating status in real time through the human-machine interface and automatically adjusts the action data of each control unit according to the real-time position of the board, ensuring stable system operation and accurate board delivery. The control system of the short-side feeding pusher device of this application achieves efficient and accurate board delivery and position correction by precisely controlling and coordinating the work of each mechanism, thereby improving production efficiency and product quality.

[0075] In this embodiment, the control unit of the left and right material pulling mechanism of the conveyor table includes a plate length sensing switch group, a plate position sensing switch group, a long and short plate sensing switch, a baffle solenoid valve, a roller motor frequency converter, a first lifting belt frequency converter, a second lifting belt frequency converter, a first lifting belt solenoid valve, and a second lifting belt solenoid valve; wherein, the plate position sensing switch group includes multiple plate position sensing switches; the multiple plate position sensing switches include a first plate position sensing switch, a second plate position sensing switch, and a third plate position sensing switch;

[0076] The left and right material pulling mechanism of the conveyor table includes a roller conveyor group, a first lifting belt group and a second lifting belt group; the conveying direction of the first lifting belt group and the conveying direction of the second lifting belt group are at 90 degrees to the conveying direction of the roller conveyor group; the frequency converter and the solenoid valve of the first lifting belt are respectively set to correspond to the first lifting belt group; the frequency converter and the solenoid valve of the second lifting belt are respectively set to correspond to the second lifting belt group.

[0077] In standby mode, the first and second lifting belt groups are in the rising position. When the plate is conveyed to the edge of the roller conveyor group, it touches the first plate arrival sensor switch, de-energizing the first and second lifting belt solenoid valves. The first and second lifting belt groups descend, and the plate falls onto the continuously rotating roller conveyor group, where it moves on the rollers.

[0078] Because the lengths of each board may be different, in order to improve efficiency, the control system automatically controls the operation mode of the second lifting belt solenoid valve based on the long and short board sensing switch signal: when the first board arrival sensing switch group and the long and short board sensing switch simultaneously sense a signal, it is determined to be a long board, and the first lifting belt group and the second lifting belt group work up and down at the same time.

[0079] When the first board arrival sensing switch group detects a signal and the long / short board sensing switch does not detect a signal, it is determined to be a short board. The board moves on the rollers of the roller conveyor group. When it is a short board, the tail of the board is disengaged from the long / short board sensing switch, and the second lifting belt solenoid valve will be energized to rise so as to pick up the next board.

[0080] The sheet moves on the roller conveyor assembly. When the head of the sheet touches the second sheet length induction switch, the CPU control unit controls the roller frequency converter to decelerate, and the sheet continues to move after deceleration. When it touches the second sheet position induction switch, the roller frequency converter stops, the roller motor stops, and the sheet stops moving.

[0081] When the roller motor stops and there is a delay, the first lifting belt solenoid valve is energized and rises again. The second lifting belt solenoid valve rises again depending on the length of the board. After the baffle is corrected, the baffle solenoid valve is de-energized and rises to release the board, sending it out of this position. The tail of the board disengages from the third board positioning sensor switch, the baffle solenoid valve is energized, and the baffle is reset.

[0082] After the program starts, the roller inverter, the first lifting belt inverter, and the second lifting belt inverter start sequentially with a delay; after the program starts, the first lifting belt solenoid valve and the second lifting belt solenoid valve are energized and rise, and the baffle solenoid valve is energized and descends; waiting for the board to arrive.

[0083] In this embodiment of the application, the hook sensing component includes a first origin sensing switch, a first hook sensing switch, and a second hook sensing switch, i.e., as shown below. Figure 10 The system includes three of the nine inductive switches. As the board moves forward continuously, the tail disengages from the first hook inductive switch until the second hook inductive switch touches the hook. At this point, the top hook drive assembly extends the hook. As the board moves forward continuously, the tail disengages from the first origin inductive switch. The rotary encoder calculates the board's position, and when the tail reaches a preset position, the hook reset drive assembly retracts the extended hook back to its original position. The top hook drive assembly includes multiple top hook solenoid valves. The hook reset drive assembly includes multiple hook reset solenoid valves. Specifically, in this embodiment, the first origin sensing switch serves as a reference point for plate position detection and as the reference zero position for the action. When the tail of the plate disengages from the first hook sensing switch, the second hook sensing switch detects whether the hook is in position so as to trigger the extension action of the hook. When the plate moves forward continuously and its tail disengages from the first hook sensing switch, the system will prepare to drive the hook to extend. The second hook sensing switch is used to confirm whether the hook has reached the correct position so as to perform the subsequent extension action. When the second hook sensing switch touches the hook, the system will trigger the top hook driving component to extend the hook.

[0084] The top hook head drive assembly is responsible for controlling the extension action of the hook head. It mainly consists of multiple top hook head solenoid valves, such as... Figure 9 The system includes 7 top hook cylinders, meaning there are also 7 top hook solenoid valves. Each guide chain has one top hook cylinder and one hook return cylinder. Each top hook solenoid valve controls the extension of one hook. When the signals from the first and second hook sensing switches meet the conditions, the controller sends a signal to the top hook solenoid valve. After being energized, the top hook solenoid valve drives the hook to extend. The extension distance and timing are precisely calculated and controlled by the controller based on encoder position data. The hook return drive assembly is used to retract the extended hook back to its original position after the material processing is completed, for the next operation. It also consists of multiple hook return solenoid valves, such as... Figure 9The system is equipped with 7 hook reset cylinders, meaning there are also 7 hook reset solenoid valves. When the tail of the board leaves the first origin induction switch, the controller starts to calculate the movement position of the board through the rotary encoder. When the tail of the board reaches the preset position, the CPU control unit sends a signal to the hook reset solenoid valve. After the hook reset solenoid valve is energized, it drives the hook to retract back to its original position, ready for the next operation. The timing and position of the reset are also precisely controlled by the rotary encoder to ensure the stability and accuracy of the system.

[0085] In the embodiments of this application, such as Figure 10 As shown, the plate alignment mechanism control unit includes a plate alignment position sensor switch, a baffle disengagement sensor switch, a bracket upper position sensor switch, a baffle middle position sensor switch, an over-thickness protection switch, a deceleration sensor switch, a plate alignment Z-axis servo driver, a plate alignment rotation servo driver, a baffle solenoid valve at the plate alignment point, and a bracket drive assembly; wherein, the bracket drive assembly includes multiple bracket solenoid valves, and the plate alignment position sensor switch, baffle disengagement sensor switch, bracket upper position sensor switch, baffle middle position sensor switch, over-thickness protection switch, and deceleration sensor switch respectively correspond to... Figure 10 The system includes six inductive switches in the *9 induction switches. The solenoid valve at the alignment point is used to drive the alignment cylinder at the alignment point in the alignment mechanism. The number of the guide chain, bracket solenoid valve, top hook solenoid valve, and hook reset solenoid valve corresponds one-to-one. The alignment Z-axis servo driver controls the vertical movement of the rotating rubber wheel, lowering it to the plate thickness position so that the rubber wheel on the alignment servo contacts the plate surface. The alignment rotation servo driver drives the rotating rubber wheel to rotate, rubbing against the plate surface to move the plate towards the stop direction, correcting the plate's lateral (relative to the feeding direction) position. The alignment position induction switch detects the plate. Whether the material reaches the baffle position at the alignment point triggers the subsequent bracket rising action; Baffle disengagement sensor switch: monitors whether the tail of the material disengages from the baffle, used to control the descent of the bracket; Bracket upper position sensor switch: confirms whether the bracket has risen to the correct position, ensuring the stability of the alignment operation; Baffle middle position sensor switch: triggers when the baffle position changes to a certain extent during the material pressing process, causing the baffle to be de-energized and released quickly; Over-thickness protection switch: used to prevent excessively thick materials from damaging the equipment; Deceleration sensor switch: triggered when the hook head approaches the end of the guide rail chain, decelerating through the CPU control unit to ensure smooth operation.

[0086] In this embodiment, the sheet material moves forward on the conveying mechanism. When the sheet material encounters the alignment baffle, it stops moving. Upon contact with the baffle, the alignment position sensor switch is triggered, causing the bracket drive assembly to raise the bracket to its designated position. This triggers the upper bracket sensor switch, and the alignment Z-axis servo driver lowers the rotating rubber wheel to the sheet thickness position, causing the upper rubber wheel to contact the sheet surface. The alignment rotation servo driver then drives the rotating rubber wheel to rub against the sheet surface, moving the sheet material towards the baffle direction to correct its lateral (relative to the feeding direction) position. After the correction time, the alignment Z-axis servo driver raises the sheet material, which then waits on the bracket for the hook to approach. The board moves forward, touching the side of the tail end of the board, pushing it forward. The front of the board presses against the baffle at the edge of the board. Because the baffle and the hook are perpendicular to the stop and parallel, the longitudinal position of the board (relative to the feeding direction) can be corrected by the pressing. The position of the baffle changes, touching the baffle center position induction switch. The baffle is de-energized and rises rapidly to release the board. The hook continues to push the board forward. When the tail end of the board leaves the baffle and the induction switch, the bracket drive assembly is de-energized, the bracket descends, and the board continues to move forward into the edge banding machine. When the hook is about to descend at the end of the guide rail, the tail end senses the deceleration induction switch, and the CPU control unit drives the frequency converter to decelerate immediately.

[0087] Specifically, in this embodiment, the alignment and correction of the board material is as follows: The board material moves forward on the conveying mechanism and stops when it encounters the baffle at the alignment point; the alignment position sensor switch is triggered, the bracket drive assembly starts, the bracket rises to the correct position, and the upper position sensor switch of the bracket is triggered; the alignment Z-axis servo driver drives the rotating rubber wheel to descend to the board thickness position, the alignment rotation servo driver starts, and the lateral position of the board material is corrected by the friction between the rotating rubber wheel and the board surface (the alignment mechanism corrects the lateral position of the board material by the friction between the rotating rubber wheel and the board surface, in conjunction with the conveying mechanism, to move the board material forward); the board material is pushed and the bracket descends: The hook moves forward, touches and pushes the board material to continue moving forward; the front of the board material presses against the baffle, and the change in the baffle position triggers the baffle. A neutral position induction switch de-energizes the baffle for rapid release; when the tail of the board detaches from the baffle and the induction switch, the bracket drive assembly de-energizes, and the bracket descends; the hook continues to push the board forward into the edge banding machine; deceleration control: when the hook descends rapidly at the end of the guide rail, the tail of the board senses the deceleration induction switch; after receiving the signal, the CPU control unit drives the drive inverter to immediately decelerate, and the drive motor decelerates to ensure that the hook does not collide with the tail of the board during descent; ensuring a smooth descent of the hook and board; avoidance action: the hook follows an arc trajectory during descent, with a speed lower than the speed of the board, to avoid scratching the tail of the board; after the hook completely detaches from the board, the drive inverter resumes normal speed, and the conveying mechanism continues to operate. In this embodiment, the board alignment mechanism control unit, through precise sensing, servo drive, and solenoid valve control, achieves precise positioning, correction, and smooth pushing of the board during the conveying process, providing a reliable guarantee for subsequent processing steps.

[0088] In this embodiment, the CPU control unit includes an industrial switch and a programmable controller.

[0089] In this embodiment, the plate length sensing switch group includes multiple plate length sensing switches. Preferably, seven plate length sensing switches are provided, each corresponding to one of the seven guide rail chains. During alignment at the roller baffle, the approximate length of the plate is calculated using signals from these seven sensing switches, thereby calculating the required number of hook actions and brackets. Of course, this mode can be applied to the left and right material pulling mechanism of the conveyor table in single-machine mode. When applied in the overall control mode, the plate alignment mechanism control unit in the pusher alignment mechanism is still used to calculate the plate length to realize the calculation of the required number of hook actions and brackets.

[0090] in,

[0091] Example 2

[0092] In Embodiment 2 of this application, a control method for a short-side feeding pusher device is provided, which includes the following steps:

[0093] Step S1: After the program starts, the two belt frequency converters start sequentially with a delay, and the two belt conveyor groups start accordingly.

[0094] Step S2: When the first and second lifting belt groups are in the rising position, and the plate is conveyed to the edge position of the roller conveyor group, the plate arrival sensing switch group is activated, and the first and second lifting belt solenoid valves are de-energized; the first and second lifting belt groups descend, and the plate falls onto the continuously rotating roller conveyor group, and the plate moves on the rollers of the roller conveyor group.

[0095] When both the board position sensing switch group and the long / short board sensing switch detect a signal, it is determined to be a long board, and the first lifting belt group and the second lifting belt group work up and down simultaneously.

[0096] When the board position sensing switch group detects a signal, but the long / short board sensing switch does not, it is determined to be a short board. The board moves on the rollers of the roller conveyor group. When it is a short board, the tail of the board disengages from the long / short board sensing switch, and the second lifting belt solenoid valve is energized and rises to receive the next board. When the board moves on the roller conveyor group, the head of the board touches the board length sensing switch group. The CPU control unit controls the roller frequency converter to decelerate, and the board continues to move after deceleration. When it touches the board position sensing switch group, the roller frequency converter stops, the roller motor stops, and the board stops moving.

[0097] When the drum motor stops and there is a delay, the first lifting belt solenoid valve is energized and rises again. The second lifting belt solenoid valve rises again depending on the length of the board. After the baffle is corrected, the baffle solenoid valve is de-energized and rises to release the board, sending the board out of this position. When the tail of the board is disengaged from the board position induction switch group, the baffle solenoid valve is energized and the baffle is reset.

[0098] After the program starts, the drum inverter, the first lifting belt inverter, and the second lifting belt inverter start sequentially with a delay; after the program starts, the first lifting belt solenoid valve and the second lifting belt solenoid valve are energized and rise, and the baffle solenoid valve is energized and descends; waiting for the board to arrive;

[0099] Step S3: Drive the motor to rotate the guide rail chain continuously, thus moving the plate forward;

[0100] Step S4: The tail of the board disengages from the first hook head sensor switch, the second hook head sensor switch touches the hook head, and the top hook head drive assembly drives the hook head to extend.

[0101] Step S5: As the plate moves forward continuously, the tail of the plate disengages from the first origin induction switch. The rotary encoder calculates the running position of the plate. When the tail of the plate reaches the preset position, the hook head reset drive component is activated to retract the originally extended hook head back to its original position.

[0102] Step S6: The sheet moves forward on the conveying mechanism. When the sheet touches the baffle at the alignment point, it stops moving. After the sheet touches the baffle at the alignment point, the alignment point sensing switch is triggered, and the bracket drive assembly drives the bracket to rise.

[0103] Step S7: After the bracket rises to the position, the upper position sensor switch of the bracket is triggered. The Z-axis servo driver of the alignment plate drives the rotating rubber wheel to descend to the plate thickness position, so that the upper rubber wheel of the alignment plate servo touches the plate surface. The rotation servo driver of the alignment plate drives the rotating rubber wheel to rub against the plate surface, causing the plate to move towards the stop direction, and corrects the lateral (relative to the feeding direction) position of the plate.

[0104] Step S8: After the calibration time is up, the Z-axis servo drive of the plate is driven to rise, and the plate waits on the bracket for the hook to come over.

[0105] Step S9: The hook moves forward and touches the side of the tail of the plate, pushing the plate forward. The front of the plate is pressed against the baffle at the plate level. Because the baffle is perpendicular to the hook and parallel to the stop, the longitudinal position of the plate (relative to the feeding direction) can be corrected by the pressing. The position of the baffle changes and touches the baffle center position sensor switch. The baffle is de-energized and rises quickly to release the plate. The hook continues to push the plate forward.

[0106] Step S10: When the tail of the board disengages from the baffle and the induction switch, the bracket drive assembly is de-energized, the bracket descends, and the board continues to move forward into the edge banding machine.

[0107] Step S11: The rotary encoder counts to obtain the hook head reset distance;

[0108] Step S12: When the hook head is descending rapidly at the end of the guide rail, the tail plate senses the deceleration sensor switch, and the CPU control unit drives the drive frequency converter to decelerate immediately.

[0109] Step S13: When the deceleration time reaches the preset time, the speed recovers and the hook reaches the preset reset position. The hook reset drive component is activated to retract the originally extended hook back to its original position.

[0110] Specifically, under the above setup, the control method achieves precise positioning, correction, and pushing of the sheet material during the conveying process through accurate sensing, driving, and control logic. This method not only improves production efficiency but also ensures the accuracy and stability of sheet material processing.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
