Description

Technical Field

[0001] This invention relates to the field of panel furniture machinery technology, and in particular to a control system and control method for a push-handle alignment device. Background Technology

[0002] In the furniture manufacturing industry, especially in the custom furniture sector, the processing of short-edge panels has become a crucial step in the production process due to the increasing demand from consumers for personalized and high-quality furniture. These panels, with their varying sizes, longer lengths, and relatively narrow widths, present numerous challenges for subsequent edge banding. Edge banding is a key step in enhancing the aesthetics, durability, and safety of furniture, and its quality and efficiency directly impact the final product quality and production costs.

[0003] However, existing edge banding technologies for short-strip panels have several shortcomings. First, due to the length and narrowness of the panels, traditional edge banding machines are often designed to handle standard-sized panels. For long and narrow panels with short-side feeding, their feeding mechanisms are ill-suited, leading to unstable panel positions during feeding, easy shifting or tilting, and severely impacting edge banding quality. Second, traditional furniture factories generally rely on manual labor or simple machinery for feeding these panels. This method is not only labor-intensive and inefficient, but also makes it difficult to guarantee the precise position and consistency of each panel during the edge banding process, and it cannot achieve automated, assembly-line production. This not only limits the expansion of production scale but also increases labor costs and product defect rates, failing to meet the demands of modern furniture manufacturing for efficient, precise, and large-scale production. Summary of the Invention

[0004] This invention addresses the problems of existing technologies by providing a control system and control method for a pusher-aligning board device, which realizes automated conveying, precise positioning, bidirectional correction and efficient obstacle avoidance of the board, thereby improving production efficiency and product quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a control system for a pusher-type plate-aligning device. The pusher-type plate-aligning device includes a hook positioning mechanism, a plate-aligning mechanism, and a conveying mechanism. The control system includes a human-machine interface unit, a CPU control unit, a hook positioning mechanism control unit, a plate-aligning mechanism control unit, and a conveying mechanism control unit. The CPU control unit, hook positioning mechanism control unit, plate-aligning mechanism control unit, and conveying mechanism control unit are respectively signal-connected to the human-machine interface unit. The hook positioning mechanism control unit, plate-aligning mechanism control unit, and conveying mechanism control unit are respectively signal-connected to the hook positioning mechanism, plate-aligning mechanism, and conveying mechanism. 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 senses 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 (calculated by the origin position switch and the rotary encoder).

[0007] The plate alignment mechanism control unit is used to align the plates on the conveying mechanism in two directions;

[0008] 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.

[0009] 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.

[0010] The top hook head drive assembly includes multiple top hook head solenoid valves.

[0011] The hook reset drive assembly includes multiple hook reset solenoid valves.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] The bracket drive assembly includes multiple bracket solenoid valves.

[0017] The CPU control unit includes an industrial switch and a programmable controller.

[0018] The present invention also provides a control method for a pusher-aligning device, which includes the following steps:

[0019] Step S1: The program starts and the equipment runs. After starting, the drive motor drives the guide rail chain to rotate continuously, moving the plate forward.

[0020] Step S2: 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.

[0021] Step S3: 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.

[0022] Step S4: 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.

[0023] Step S5: 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.

[0024] Step S6: 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.

[0025] Step S7: 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 induction switch. The baffle is de-energized and rises quickly to release the plate. The hook continues to push the plate forward.

[0026] Step S8: 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.

[0027] Step S9: The rotary encoder counts to obtain the hook head reset distance;

[0028] Step S10: 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 inverter to decelerate immediately.

[0029] Step S11: When the deceleration time reaches the preset time, the speed recovers and the hook head reaches the preset reset position, the hook head reset drive component is activated to retract the originally extended hook head back to its original position.

[0030] The beneficial effects of this invention are:

[0031] During operation, the system initializes as follows: After the CPU control unit is powered on, it performs self-test and initialization settings to ensure that all control units and hardware devices are in normal working condition; the human-machine interface (HMI) displays the initial interface and waits for user input commands; startup control: the user inputs a startup command through the HMI, and after receiving the command, the CPU control unit sends a startup signal to each control unit; the conveyor mechanism control unit starts the drive inverter, which controls the drive motor to start running, driving the guide chain to rotate; the sheet metal is placed on the conveyor mechanism and moves forward as the guide chain rotates; the hook positioning mechanism control unit monitors the position of the hook head in real time through the hook head sensing component; when the sheet metal moves to the designated position, the hook head sensing component triggers a signal, energizing the top hook head drive component and controlling the hook head at the corresponding position to extend; after the hook head extends, it maintains its position through friction until it needs to be reset, at which point the hook head reset drive component is energized, controlling the hook head to retract back to its original position; when the sheet metal reaches the alignment mechanism, the alignment mechanism control unit is activated: the alignment mechanism control unit controls the alignment mechanism on the conveyor mechanism... The sheet material is aligned in two directions; after alignment, the sheet material is released; the sheet material continues to move forward to the next process under the push of the hook; when the hook approaches the end of the guide chain, the conveying mechanism control unit controls the drive frequency converter to decelerate; the drive motor decelerates to ensure that the hook does not collide with the tail of the sheet material during descent; the hook moves along an arc trajectory during descent, at a speed lower than the speed of the sheet material, to avoid scratching the tail of the sheet material; after the hook completely disengages from the sheet material, the drive frequency converter returns to normal speed, and the conveying mechanism continues to operate; the guide chain of this invention operates in a cycle: the system continuously receives new sheet materials, repeating the above-mentioned conveying, positioning, alignment, release, and deceleration and avoidance process; each control unit monitors the equipment status in real time to ensure stable system operation; the human-machine interface unit displays the system operating status and parameters in real time; in case of fault or abnormal situation, the CPU control unit will trigger an alarm and display error information on the human-machine interface unit; through the above steps, the control system and control method of this pusher-aligning sheet material device realize automated conveying, precise positioning, bidirectional alignment, and efficient avoidance of sheet materials, improving production efficiency and product quality.

[0039] 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.

[0040] Example 1

[0041] A control system for a pusher-and-align plate device 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 mounted on one side of each guide rail chain. The hook positioning mechanism is mounted on the guide rail chains. The alignment mechanism includes a baffle and a rotating rubber wheel mounted on one side of the baffle. The control system includes a human-machine interface unit, a CPU control unit, a hook positioning mechanism control unit, an alignment mechanism control unit, and a conveying mechanism control unit. The CPU control unit, hook positioning mechanism control unit, alignment mechanism control unit, and conveying mechanism control unit are respectively signal-connected to the human-machine interface unit. The hook positioning mechanism control unit, alignment mechanism control unit, and conveying mechanism control unit are respectively signal-connected to the hook positioning mechanism, alignment mechanism, and conveying mechanism.

[0042] The hook positioning mechanism control unit includes a hook sensing component, a top hook driving component, and a hook reset 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 reset 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 to control the hook to retract and return to its original position).

[0043] The plate alignment mechanism control unit is used to align the plates on the conveying mechanism in two directions;

[0044] 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.

[0045] Specifically, in the operation of this embodiment, the system initializes as follows: After the CPU control unit is powered on, it performs self-test and initialization settings to ensure that each control unit and hardware device is in normal working condition; the human-machine interface (HMI) displays the initial interface and waits for the user to input operation commands; start control: the user inputs a start command through the HMI, and after receiving the command, the CPU control unit sends a start signal to each control unit; the conveyor mechanism control unit starts the drive inverter, which controls the drive motor to start running, driving the guide rail chain to rotate; the plate is placed on the conveyor mechanism and moves forward as the guide rail chain rotates; the hook positioning mechanism control unit monitors the position of the hook head in real time through the hook head sensing component; when the plate moves to the designated position, the hook head sensing component triggers a signal, the top hook head drive component is energized, and the hook head at the corresponding position is extended; after the hook head is extended, it maintains its position through friction until it needs to be reset, at which point the hook head reset drive component is energized, and the hook head is retracted back to its original position;

[0046] When the sheet metal reaches the alignment mechanism, the alignment mechanism control unit is activated. This control unit controls the alignment mechanism to align the sheet metal on the conveyor in two directions. After alignment, the sheet metal is released. Driven by the hook, the sheet metal continues to move forward to the next process. When the hook approaches the end of the guide chain, the conveyor control unit controls the drive inverter to decelerate. The drive motor decelerates to ensure the hook does not collide with the tail of the sheet metal during descent. The hook follows an arc trajectory during descent, with a speed lower than the sheet metal's speed to avoid scratching the tail of the sheet metal. After the hook completely detaches from the sheet metal, the drive inverter resumes normal speed. The conveying mechanism continues to operate; the guide chain in this embodiment of the application works in a cyclical manner: the system continuously receives new plates and repeats the above-mentioned processes of conveying, positioning, correction, release, and deceleration and avoidance; each control unit monitors the equipment status in real time to ensure stable system operation; the human-machine interface unit displays the system operating status and parameters in real time; in case of fault or abnormal situation, the CPU control unit will trigger an alarm and display error information on the human-machine interface unit; through the above steps, the control system of the pusher plate alignment device realizes automated conveying, precise positioning, bidirectional correction, and efficient avoidance of plates, thereby improving production efficiency and product quality.

[0047] 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 5The system includes three inductive switches. When the board moves forward continuously, the tail of the board 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. When the board moves forward continuously, the tail of the board disengages from the first origin inductive switch. The rotary encoder calculates the board's position. When the tail reaches a preset position, the hook reset drive assembly activates, retracting 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 origin sensing switch, the system begins to calculate the moving position of the plate through a rotary encoder. The first hook sensing switch is used to detect whether the plate has moved far enough 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 prepares to drive the hook to extend. The second hook sensing switch is used to confirm whether the hook has reached the correct position in order to perform the subsequent extension action. When the second hook sensing switch touches the hook, the system triggers the top hook drive assembly to extend the hook.

[0048] 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 5 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 5 The 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.

[0049] In the embodiments of this application, such as Figure 6As 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 6 One of the inductive switches in the *6 is used to drive the baffle 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 can contact 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 baffle direction, correcting the lateral (relative to the feeding direction) position of the plate; the alignment position inductive 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 rise quickly to release the material; Overthickness 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.

[0050] 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 and 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 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 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 of the board senses the deceleration induction switch. The CPU control unit drives the frequency converter to decelerate immediately.

[0051] Specifically, in this embodiment, the plate alignment and correction are as follows: The plate moves forward on the conveying mechanism and stops when it encounters the alignment baffle; 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 plate thickness position, the alignment rotation servo driver starts, and the lateral (relative to the feeding direction) position of the plate is corrected by the friction between the rotating rubber wheel and the plate surface (the alignment mechanism corrects the lateral position of the plate by the friction between the rotating rubber wheel and the plate surface, in conjunction with the conveying mechanism to drive the plate forward); Plate pushing and bracket descent: The hook moves forward, touches and pushes the plate to continue moving forward; the front of the plate squeezes the baffle, and the change in the position of the baffle triggers the alignment position sensor switch. The baffle is de-energized and rises rapidly to allow passage when the baffle's center position induction switch is activated. When the tail of the sheet material detaches from the baffle and the induction switch, the bracket drive assembly is de-energized, and the bracket descends. The hook continues to push the sheet material forward into the edge banding machine. Deceleration control: When the hook descends rapidly at the end of the guide rail, the tail of the sheet material senses the deceleration switch. Upon 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 sheet material during descent, ensuring a smooth descent of both the hook and the sheet material. Avoidance action: The hook follows an arc trajectory during descent, with a speed lower than the sheet material's speed, avoiding scratches on the tail of the sheet material. After the hook completely detaches from the sheet material, the drive inverter resumes normal speed, and the conveying mechanism continues operation. In this embodiment, the sheet material alignment mechanism control unit, through precise sensing, servo drive, and solenoid valve control, achieves precise positioning, correction, and smooth pushing of the sheet material during conveying, providing reliable assurance for subsequent processing steps.

[0052] In this embodiment, the CPU control unit includes an industrial switch and a programmable controller.

[0053] Example 2

[0054] In a second embodiment of this application, a control method for a pusher-aligning plate device is provided, which includes the following steps:

[0055] Step S1: The program starts and the equipment runs. After starting, the drive motor drives the guide rail chain to rotate continuously, moving the plate forward. This is the beginning of the entire control method, ensuring that the plate can move forward continuously and stably.

[0056] Step S2: 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; in order to prepare the hook head to push the board, it is ensured that the hook head can extend and contact the board at the correct time.

[0057] Step S3: As the board moves forward continuously, the tail of the board disengages from the first origin induction switch. The rotary encoder calculates the running position of the board. When the tail of the board reaches the preset position, the hook head reset drive component is activated to retract the originally extended hook head back to its original position. This ensures that the hook head can accurately reset after pushing the board head, preparing for the next push.

[0058] Step S4: The sheet material moves forward on the conveying mechanism. When the sheet material touches the baffle at the alignment point, it stops moving. After the sheet material touches the baffle at the alignment point, the alignment point induction switch is triggered, and the bracket drive assembly drives the bracket to rise. This is to perform preliminary positioning and support of the sheet material.

[0059] Step S5: After the bracket rises to the correct position, the upper induction 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 rotating rubber wheel on the alignment plate servo touches the plate surface. The alignment plate rotation servo driver drives the rotating rubber wheel to rub against the plate surface, causing the plate to move towards the stop direction, correcting the plate's lateral (relative to the feeding direction) position. This is a key step in plate alignment, ensuring the accuracy of the plate in subsequent processing.

[0060] Step S6: After the calibration time is up, the Z-axis servo driver of the plate is driven to rise, and the plate waits on the bracket for the hook to come over; in preparation for the next stage of pushing operation.

[0061] Step S7: 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 induction switch. The baffle is de-energized and rises quickly to release the plate. The hook continues to push the plate forward.

[0062] Step S8: 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.

[0063] Step S9: The rotary encoder counts to obtain the hook head reset distance;

[0064] Step S10: 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 inverter to decelerate immediately.

[0065] Step S11: When the deceleration time reaches the preset time, the speed recovers and the hook head reaches the preset reset position, the hook head reset drive component is activated to retract the originally extended hook head back to its original position.

[0066] Specifically, under the above configuration, the control method of the pusher-aligning device achieves precise positioning, correction, and pushing of the board during the conveying process through precise sensing, driving, and control logic. This method not only improves production efficiency but also ensures the accuracy and stability of board processing.

When the tail of the plate reaches a preset position, the hook head reset driving component activates, retracting the originally extended hook head back to its original position.

2. The control system of the pusher-aligning plate device according to claim 1, characterized in that: The top hook drive assembly includes multiple top hook solenoid valves.

3. The control system of the push-handle alignment device according to claim 1, characterized in that: The hook reset drive assembly includes multiple hook reset solenoid valves.

4. The control system of the push-handle alignment device according to claim 1, characterized in that: 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. 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 at the alignment point, the alignment position sensor switch is triggered. The bracket drive assembly drives the bracket to rise to the correct position, triggering the upper position sensor switch of the bracket. 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 to correct the lateral 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. 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. Through pressing, the longitudinal position of the board is corrected. 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 board. The hook continues to push the board forward. When the tail of the board disengages from the baffle and the sensor switch, the bracket drive component is de-energized, the bracket descends, and the board continues to move forward into the edge banding machine. 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.

5. The control system of the pusher-aligning plate device according to claim 4, characterized in that: The bracket drive assembly includes multiple bracket solenoid valves.

6. The control system of the push-handle alignment device according to claim 1, characterized in that: The CPU control unit includes an industrial switch and a programmable controller.

7. A control method for a push-hand alignment device, characterized in that, Includes the following steps: Step S1: The program starts and the equipment runs. After starting, the drive motor drives the guide rail chain to rotate continuously, moving the plate forward. Step S2: 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. Step S3: 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. Step S4: 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. Step S5: 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 correct the lateral position of the plate. Step S6: 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. Step S7: 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. Through pressing, the longitudinal position of the board is corrected. 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 board. The hook continues to push the board forward. Step S8: 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. Step S9: The rotary encoder counts to obtain the hook head reset distance; Step S10: 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 inverter to decelerate immediately. Step S11: When the deceleration time reaches the preset time, the speed recovers and the hook head reaches the preset reset position, the hook head reset drive component is activated to retract the originally extended hook head back to its original position.
