Description

Technical Field

[0001] The invention relates to the technical field of edge banding machines, and in particular to a two-host four-edge banding line control system and a method thereof. Background Art

[0002] In the panel furniture industry, edge banding is an important part of ensuring product quality and appearance. The traditional edge banding method mainly relies on single-machine edge banding equipment, that is, each edge banding machine is only responsible for processing one edge of the workpiece, and the entire four-side edge banding process requires manual handling of the workpiece to different locations for repeated operations. This traditional method has the following significant problems: since the workpiece needs to be manually handled after each edge banding, the labor input is large and the labor cost remains high; after a single edge banding is completed, it needs to be repositioned, and the entire process is cumbersome and time-consuming, which greatly limits production efficiency; manual operation is prone to introduce errors, affecting the quality consistency of the final product; in addition, there are also some four-host online automatic four-edge banding systems on the market, which use four edge banding machines to process the four edges of the workpiece respectively, thereby realizing automatic edge banding. However, this type of system also faces challenges: high equipment costs, huge investments in four edge banding machines and their supporting equipment, which increases the initial investment burden of the enterprise; high site use costs: multiple devices occupy a large space, which is a big challenge for enterprises with limited plant area. Although both of the above methods can complete the task of edge banding on four sides, they fail to solve the problems of cost control, production efficiency improvement and automation. Especially for small and medium-sized enterprises, how to achieve efficient and low-cost edge banding technology under limited funds and technical conditions has become an urgent problem to be solved. Summary of the invention

[0003] In view of the problems of the prior art, the present invention provides a two-host four-side sealing online control system and method, so that the workpiece can complete the edge sealing processing of all four sides at one time without falling to the ground, and no multiple manual interventions are required; the degree of automation is high, and full-process automatic control is realized, the influence of human factors is reduced, and the stability and reliability of production are improved; the cost is saved, and the equipment procurement cost and site occupancy rate are greatly reduced; the flexibility and adaptability are strong, and it is suitable for the processing needs of workpieces of various types and sizes; the present invention not only solves the problems of low efficiency and high cost in traditional edge sealing processes, but also has made remarkable progress in improving the level of automation, and provides a more economical and efficient solution for the panel furniture industry.

[0019] Initial entry: the workpiece enters the line platform A101 of the short edge processing system of section A from the processing entrance; transportation and detection: the line system determines whether each line platform from line platform A102 to line platform A105 is idle in turn to ensure that the workpiece can pass through each platform smoothly; the sensor triggers the high-speed camera scanning acquisition unit to scan the workpiece QR code to obtain preliminary processing information, and the information is exchanged with the automatic edge banding machine system;

[0020] Step S2: Processing preparation:

[0021] Entering the pre-processing preparation area, when the system confirms that the line platform A106 is idle, the workpiece enters this platform; at this time, the line system further checks whether the No. 1 edge banding machine allows the board to enter. Once the conditions are met, the workpiece is transported to the No. 1 edge banding machine;

[0022] Processing technology information transmission: the scanning acquisition unit sends the processing technology information read from the workpiece QR code to the human-machine dialogue interface PC unit through the MODBUS TCP communication protocol, and the human-machine dialogue interface then transmits this information to the edge banding machine programmable controller unit through the MODBUS TCP protocol;

[0023] The first short edge machining is performed to start machining:

[0024] The edge banding machine programmable controller unit calculates the time point when the workpiece reaches the preset position of each functional component based on the received processing information, and controls multiple edge banding processing functional units through PTO high-speed pulses to start the first processing of a short side of the workpiece;

[0042] The programmable controller unit of the edge banding machine calculates the time point when the workpiece reaches the preset position of each functional component based on the received processing technology information, and controls each edge banding processing functional unit through PTO high-speed pulse to start the first processing of one long side of the workpiece.

[0043] Completion of the first long edge processing: After the processing is completed, the No. 2 edge banding machine determines whether the line platform B109 is idle, and then sends the workpiece to this platform;

[0044] Confirmation of processing times and rotation action: Confirmation of processing times: The scanning and acquisition unit of line body B scans the workpiece QR code again, collects the processing times information, and feeds it back to the automatic line body control system; the system determines the action as automatic rotation based on the processing times information (first long edge processing) to prepare for the second long edge processing;
