Description

Technical Field

[0001] The invention relates to the technical field of woodworking machinery, and in particular to a control system and a control method of a short-side feeding pusher device. Background Art

[0002] In the furniture customization industry, as consumers' demand for personalization and customization grows, the demand for processing short-edged boards has also increased significantly. These boards are usually long and narrow, and the edge banding process is particularly complicated because the edge banding machine is designed to feed short edges. In traditional processing methods, the side of the board is usually pushed into the edge banding machine by a pusher mechanism, but this method has obvious defects when processing narrow and long boards: the board is easily bent and deformed during the pushing process, affecting the quality and appearance of the final product.

[0003] In addition, since the length and width of each batch of boards are mostly different, this poses a great challenge to automated processing. At present, in order to ensure the reliable position of the workpiece during feeding, most domestic furniture factories still rely on manual feeding operations. This method is not only inefficient, but also difficult to achieve assembly line production, which seriously restricts the improvement of production efficiency and capacity.

[0004] In view of the above situation, the furniture customization industry urgently needs an automated processing solution that can effectively process narrow and long boards, solve the problem of conveying transition when sealing short edges, and can adapt to boards of different sizes. This solution should be able to significantly improve production efficiency, reduce labor costs, and ensure the quality and precision of processed parts to meet the market demand for high-quality, personalized furniture products.

[0017] When in standby mode, the first lifting belt group and the second lifting belt group are in the ascending position. When the plate is transported to the side position of the roller conveyor group, the plate in place sensing switch group is touched, and the first lifting belt solenoid valve and the second lifting belt solenoid valve are powered off; the first lifting belt group and the second lifting belt group are lowered, and the plate falls onto the continuously rotating roller conveyor group, and the plate moves on the roller of the roller conveyor group;

[0018] When the board in place sensing switch group and the long and short board sensing switch sense signals at the same time, it is judged as a long board, and the first lifting belt group and the second lifting belt group work up and down at the same time;

[0019] When the board in place induction switch group senses a signal, and the long and short board induction switch has no signal, it is judged as 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 separated from the long and short board induction switch, and the second lifting belt solenoid valve will be energized and rise to take over the next board.

[0020] The plate moves on the roller conveyor group. When the plate head hits the plate length sensing switch group, the CPU control unit controls the deceleration of the roller inverter, and the plate continues to move after deceleration; when it hits the plate in-place sensing switch group, the roller inverter stops, the roller motor stops, and the plate stops moving;

After the baffle is calibrated, the baffle solenoid valve is de-energized and raised to release the plate, and the plate is sent out of this position. The tail of the plate is separated from the plate in place induction switch group, the baffle solenoid valve is energized, and the baffle is reset;

[0028] The plate moves forward on the conveying mechanism, and stops moving when it hits the baffle at the plate level. After the plate hits the baffle at the plate level, the plate level position induction switch is triggered, and the bracket drive assembly drives the bracket to rise to the position, triggering the bracket upper position induction switch. The plate leveling Z-axis servo driver drives the rotating rubber wheel to descend to the plate thickness position, so that the plate leveling servo upper rubber wheel touches the plate surface, and the plate leveling rotation servo driver drives the rotating rubber wheel to rub against the plate surface to drive the plate to move toward the stop direction, correcting the lateral position of the plate (relative to the feeding direction). After the correction time is up, the plate leveling Z-axis servo driver drives it to rise, and the plate waits for the hook head to come over on the bracket;

[0029] The hook moves forward and touches the side of the tail of the plate, pushing the plate forward. The front of the plate squeezes the baffle at the plate level. Because the baffle and the hook are perpendicular to the stop and parallel, the longitudinal position of the plate (relative to the feeding direction) can be corrected by squeezing. The baffle position changes and touches the baffle mid-position induction switch. The baffle is powered off and quickly rises to release. The hook continues to push the plate forward. When the tail of the plate is separated from the baffle and the induction switch, the bracket drive assembly is powered off, the bracket drops, and the plate continues to move forward and enters the edge banding machine.

[0037] The drum motor stops, delays, the first lifting belt solenoid valve is energized and rises again, and the second lifting belt solenoid valve rises again depending on the length of the plate. After the baffle is calibrated, the baffle solenoid valve is de-energized and raised to release the plate, and the plate is sent out of this position. The tail of the plate is separated from the plate in place induction switch group, the baffle solenoid valve is energized, and the baffle is reset;

[0038] After the program is started, the drum inverter, the first lifting belt inverter and the second lifting belt inverter are delayed in sequence. After the program is started, the first lifting belt solenoid valve and the second lifting belt solenoid valve are energized to rise, and the baffle solenoid valve is energized to fall.

[0042] Step S6, the plate moves forward on the conveying mechanism, and stops moving when the plate hits the baffle at the plate level position. After the plate hits the baffle at the plate level position, the plate level position sensing switch is triggered, and the bracket driving component drives the bracket to rise;

[0043] Step S7, after the bracket rises to the position, the bracket upper position induction switch is triggered, and the Z-axis servo driver of the plate alignment drives the rotating rubber wheel to descend to the plate thickness position, so that the upper rubber wheel of the plate alignment servo touches the plate surface, and the plate alignment rotation servo driver drives the rotating rubber wheel to rub against the plate surface to drive the plate to move toward the stop direction, thereby correcting the lateral position of the plate (relative to the feeding direction);

[0044] Step S8, after the calibration time is up, the Z-axis servo driver of the plate is driven to rise, and the plate is on the bracket waiting for the hook to come over;
