Description

Technical Field

[0001] The invention relates to the technical field of panel furniture machinery, and in particular to a control system and a control method of a handle-pushing panel-aligning device. Background Art

[0002] In the furniture manufacturing industry, especially in the furniture customization industry, as consumers' demand for personalized and high-quality furniture grows, the processing of short-edged boards has become an important part of the production process. Due to the different sizes, long lengths and relatively narrow widths of these boards, subsequent edge banding brings many challenges. Edge banding is a key step in improving the aesthetics, durability and safety of furniture, and its quality and efficiency directly affect the final quality and production cost of the product.

[0003] However, there are many deficiencies in the edge banding process for short-edged boards in the prior art. First, due to the long and narrow characteristics of the boards, the design of traditional edge banding machines often focuses on processing boards of standard sizes. For long and narrow boards with short edges, its feeding mechanism is difficult to effectively adapt, resulting in unstable position of the boards during the feeding process, which is prone to offset or tilt, seriously affecting the quality of edge banding. Secondly, when processing such boards, traditional furniture factories generally rely on manual or simple mechanical feeding operations. This method is not only labor-intensive and inefficient, but also difficult to ensure the precise position and consistency of each board during the edge banding process, and it is even more impossible to achieve an automated, assembly-line production model. This not only limits the expansion of production scale, but also increases labor costs and product failure rates, making it difficult to meet the needs of the modern furniture manufacturing industry for efficient, precise, and large-scale production. Summary of the invention

[0004] In view of the problems of the prior art, the present invention provides a control system and a control method of a push-hand plate-aligning device, which realizes the automatic transportation, precise positioning, two-way correction and efficient avoidance of plates, and improves production efficiency and product quality.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides a control system for a push-hand plate-aligning device, wherein the push-hand plate-aligning device comprises a hook head positioning mechanism, a plate-aligning mechanism and a conveying mechanism, wherein the control system comprises a human-machine dialogue unit, a CPU control unit, a hook head positioning mechanism control unit, a plate-aligning mechanism control unit and a conveying mechanism control unit, wherein the CPU control unit, the hook head positioning mechanism control unit, the plate-aligning mechanism control unit and the conveying mechanism control unit are respectively connected to the human-machine dialogue unit by signal, and the hook head positioning mechanism control unit, the plate-aligning mechanism control unit and the conveying mechanism control unit are respectively connected to the hook head positioning mechanism, the plate-aligning mechanism and the conveying mechanism by signal; the hook head positioning mechanism control unit comprises a hook head sensing component, a top hook head driving component and a hook head resetting driving component, wherein the hook head sensing component is used to sense the position of the hook head and the plate, wherein the top hook head driving component controls the hook head to extend according to the position of the hook head and the plate sensed by the hook head sensing component, and wherein the hook head resetting driving component controls the hook head to retract and reset according to the position of the hook head sensed by the hook head sensing component (the origin position switch and the rotary encoder calculate the hook head running position).

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

[0009] Among them, the hook head sensing component includes a first origin sensing switch, a first hook head sensing switch and a second hook head sensing switch; when the plate moves forward continuously, the tail of the plate is separated from the first hook head sensing switch until the second hook head sensing switch touches the hook head, and the top hook head driving component drives the hook head to extend; when the plate moves forward continuously, the tail of the plate is separated from the first origin sensing switch, and the running position of the plate is calculated by the rotary encoder. When the tail of the plate reaches the preset position, the hook head reset driving component is activated to retract the originally extended hook head to its original position.

[0010] Wherein, the top hook head driving assembly includes a plurality of top hook head solenoid valves.

[0011] Wherein, the hook head reset drive component includes a plurality of hook head reset solenoid valves.

[0012] The control unit of the plate alignment mechanism includes a plate alignment position sensing switch, a baffle detachment sensing switch, a bracket upper position sensing switch, a baffle middle position sensing switch, an over-thickness protection switch, a deceleration sensing switch, a plate alignment Z-axis servo driver, a plate alignment rotation servo driver, a baffle alignment solenoid valve and a bracket drive assembly;

[0013] 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;

[0014] 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.

[0015] When the hook head is about to drop to the end of the guide rail, the tail of the board senses the deceleration sensing switch and drives the drag inverter to decelerate immediately through the CPU control unit.

[0016] Wherein, the bracket driving assembly includes a plurality of bracket solenoid valves.

[0017] Wherein, the CPU control unit includes an industrial switch and a programmable controller.

[0018] The present invention also provides a control method for a push-hand plate-aligning device, which comprises the following steps:

[0019] Step S1, the program starts, the equipment runs, after starting, the drag motor drives the guide rail chain to rotate continuously and drive the plate to move forward;

[0020] Step S2, the tail of the plate is separated from the first hook head sensing switch, the second hook head sensing switch touches the hook head, and the top hook head driving component drives the hook head to extend;

[0021] Step S3, when the tail of the plate is separated from the first origin sensing switch during the process of the plate moving forward uninterruptedly, the running position of the plate is calculated by the rotary encoder, and when the tail of the plate reaches the preset position, the hook head reset driving assembly is actuated to retract the originally extended hook head to its original position;

[0022] Step S4, 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;

[0023] Step S5, 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);

[0024] Step S6: 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;

[0025] Step S7, the hook moves forward and touches the side of the tail of the plate, pushing the plate forward, and 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, and the baffle position changes, touching the baffle mid-position induction switch, the baffle is powered off and quickly rises to release, and the hook continues to push the plate forward;

[0026] Step S8, when the tail of the plate is separated from the baffle and the sensing switch, the bracket drive assembly is powered off, the bracket descends, and the plate continues to move forward and enters the edge banding machine;

[0027] Step S9, the rotary encoder counts to obtain the hook reset distance;

[0028] Step S10, when the hook head is about to drop at the end of the guide rail, the tail of the board senses the deceleration sensing switch, and the CPU control unit drives the drag inverter to decelerate immediately;

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