Technical Field

[0001] The present invention relates to the technical field of furniture machinery, and in particular to a control system and a control method for a square edge banding feeding device. Background Art

[0002] In the furniture industry, edge banding is the process of squaring the processed boards to the required size, so that the size required by the design is achieved and the accuracy error of each edge is within the acceptable range.

[0003] At present, after the plate is cut, there are errors in the diagonal size and the verticality of the two sides.

[0195] Embodiment 2

[0196] Please refer to Figure 7 , is a flow chart of a control method for a square edge banding feeding device provided in Embodiment 1 of the present invention. The method is applicable to a scenario where a square edge banding feeding device is automatically controlled. The method is implemented by a control system of the square edge banding feeding device, which can be implemented by software and / or hardware. The method specifically comprises the following steps:

[0197] S100, receiving a working mode selection instruction through a human-machine dialogue unit;

[0198] S200. According to the working mode selection instruction, the central control unit controls the square edge banding feeding device to work in a working mode corresponding to the working mode selection instruction between the master control working mode and the stand-alone working mode.

[0199] It should be noted that the main problem solved by this embodiment is to achieve the effect of fixed length and width for processed panels by square edge banding and intelligent production. The full closed-loop control of the servo is used to achieve precise positioning and reduce processing errors. The edge banding feed is prone to deviation due to the asynchronous speed. Electronic gear synchronous control is used to synchronize the speed and position of the edge banding machine and smoothly feed the edge banding machine for processing. The master control data is used to control the actions of each mechanism to reduce problems such as human operating errors and low efficiency. Intelligent production is achieved. Two working modes can meet different needs. The master control working mode is suitable for large-scale, batch production, which is centrally controlled by the master control to reduce manpower requirements. The stand-alone working mode is suitable for use during the debugging process or for processing a small number of panels without data.

[0200] In this embodiment, if Figure 8 As shown, the master control working mode includes:

[0201] S210, receiving various production process parameters transmitted externally;

[0204] S213, start the program, the pusher mechanism moves to the waiting position, the position data that the pusher mechanism needs to move is determined according to the processing technology transmitted by the master control, when the long side process is in progress, the pusher mechanism waits and does not move, when the short side process is in progress, the pusher mechanism calculates the advancing distance according to the board width transmitted by the master control;

[0205] S214, start the program, the gantry side positioning control unit, the long side push servo motor and the long side push servo motor move to the waiting processing position, the position data to be moved is determined according to the processing process transmitted by the master control, when the long side is sealed, it moves to the board width position to wait, when the short side is sealed, it moves to the board length position to wait;

[0206] S215, starting the program, the conveying control unit starts and stops together with the conveyor belt of the rear edge banding machine, and the speed remains completely consistent;

[0207] S216, when the conveying starts, a processing permission signal is issued to control the solenoid valve corresponding to the baffle to release; the plate enters the detection control unit, and after the detection and transmission size are consistent, it passes through the pressure beam mechanism, triggers the detection photoelectric of the pressure beam, and controls the solenoid valve of the pressure beam to move in turn, and the cylinder presses down to reach the processing detection photoelectric, and the gantry side positioning control unit moves in place according to the plate size, and the lifting solenoid valve and the blocking solenoid valve are activated to lift the plate, and the side solenoid valve controls the cylinder to move to position the plate, and then the pusher servo motor is activated to control the push claw to push the plate from the tail of the plate to the edge banding machine at a uniform speed for processing; according to the plate data issued by the master control, the above processing is repeated, such as Fig. 9 shown.

[0208] In this embodiment, if Figure 8 As shown, the stand-alone working mode includes:

[0209] S310, receiving information of components to be started and related processing data that are manually set;

[0210] S311. After the data setting is completed, the positioning button signal is received by manual clicking, and each mechanism is controlled to be positioned to the set position. After completion, the program is started; the conveyor belt runs and a feeding permission signal is issued. The related actions are consistent with those in the master control working mode.
