Description

Technical Field

[0001] The present invention relates to the technical field of edge banding machines, and particularly to an edge banding machine glue replacement control system and method. Background Art

[0002] An edge banding machine is a device used for edge banding treatment of a board. By pasting an edge banding strip on the edge of the board, it can not only protect the edge of the board from moisture and cracking, but also play a role in beautifying the appearance. In modern furniture production, the edge banding machine has become an indispensable key device. With the development of the industry, the requirements for the functions and performance of the edge banding machine are getting higher and higher. In the existing technology, the glues used in mainstream edge banding machines are mainly divided into two categories: light color and dark color. The glue replacement method mainly relies on manual operation. The operator needs to manually select the glue of the appropriate color by relying on experience and observing the colors of the board and the edge banding strip. In terms of adjusting the glue amount, it is also mostly achieved through manual adjustment. Therefore, there are the following disadvantages: 1. Low accuracy: When detecting the colors of the board and the edge banding strip, it is easily affected by factors such as light changes and specular reflections, resulting in inaccurate color recognition, and then selecting the wrong glue color, which affects the edge banding effect; 2. Complicated operation: Relying on manual selection of glue and adjustment of glue amount requires the operator to have certain experience and skills. The operation process is cumbersome, increasing the labor intensity and the probability of errors; 3. Serious glue waste: Since the glue amount cannot be automatically adjusted according to the roughness of the processed surface of the board, there are often situations where the glue amount is too much or too little. Excessive glue amount not only causes glue waste, but also forms excess glue lines on the surface of the board, affecting the aesthetics of the product. Too little glue amount may lead to insecure edge banding, reducing the product quality; 4. Single function: It can only perform single-color glue application and cannot meet the diverse color requirements in the market, restricting the design and production of products and being difficult to adapt to the increasingly rich product types in the furniture industry; 5. Low edge banding quality: Due to the combined effects of color mismatch and unreasonable glue amount, problems such as large glue lines and inconsistent colors occur in the processed products, and the overall quality is difficult to guarantee, reducing the market competitiveness of the products.

[0030] Please refer to Figure 7, an embodiment provided by the present invention: a method for controlling glue replacement of an edge banding machine, including Step 1, system initialization; Step 2, incoming material detection; Step 3, data processing; Step 4, control execution; Step 5, feedback optimization;

[0031] In the above Step 1, the edge banding machine is turned on, and initialization operations are performed on the detection module 1, data processing module 2, control execution module 3, monitoring module 4, and expansion module 5. The initialization operations are specifically as follows: the detection module 1 and the control execution module 3 perform initialization checks and calibrations, the data processing module 2 performs initialization settings on the basic parameters for the system operation, and loads the algorithms required for data processing. The monitoring module 4 performs initialization settings on the monitoring parameters, and the expansion module 5 performs initialization configurations on the data interaction network and the added expansion functions;

[0032] In the above Step 2, the detection module 1 respectively collects the color data of the board and the edge banding tape from the feeding platform and the tape feeding platform, collects the roughness data of the processed surface of the board, and sends the collected data to the data processing module 2;

[0033] In the above Step 3, the data processing module 2 receives and analyzes the color and roughness data collected by the detection module 1, determines the optimal glue color and glue application amount formula, generates and sends a control instruction to the control execution module 3;

[0034] In the above Step 4, the control execution module 3 performs glue replacement, glue application, and edge banding actions according to the control instruction;

[0035] In the above Step 5, the monitoring module 4 continuously monitors the system operation, generates feedback data to the data processing module 2, the data processing module 2 adjusts and optimizes the control instruction, and the control execution module 3 executes the optimized control instruction. Specifically: the monitoring module 4 compares the actual and set glue application amounts through the glue amount monitoring unit 41, and when the deviation exceeds the range, it feeds back to the data processing module 2. It checks the glue color through the glue color monitoring unit 42, and when the colors are inconsistent, it gives an alarm reminder and feeds back to the data processing module 2. The feedback control unit 24 of the data processing module 2 optimizes the control instruction according to the feedback data and sends it to the control execution module 3 for execution.

[0036] Based on the above, the advantages of the present invention are as follows. When the invention is in use, after starting the edge banding machine and detecting that the feeding is in place, the detection module 1 triggers a detection action once. The color detection unit 11 triggers a color detection of the board and the edge band once, and at the same time, the roughness detection unit 12 triggers a roughness detection of the processed surface of the board once. After the detection is completed, the color and roughness data are transmitted to the data processing module 2 for calculation. The color data processing unit 21 analyzes the color data and compares it with the preset formula to determine the glue color requirement. The roughness data processing unit 22 evaluates the roughness degree data to determine the grade. The formula matching unit 23 combines the results of the two to select the glue color and the glue application amount formula, generates and issues a control instruction to the control execution module 3. At the same time, the system status monitoring unit 43 in the monitoring module 4 detects whether the double PUR glue supply system is ready, and the glue amount monitoring unit 41 detects whether there is glue in the glue pot, and feeds back the detection results to the data processing module 2 to provide a basis for the subsequent glue switching decision. The data processing module 2 compares the current color data with the previous data and makes the following decisions in combination with the situation of whether there is glue in the glue pot: If the data is consistent, the system does not act, maintains the status quo, and continues to use the current glue for glue application. If the data is inconsistent and there is no glue in the glue pot, the glue switching control unit 31 in the control execution module 3 directly switches to the mixing mode corresponding to the detected color for the glue application action. If the data is inconsistent and there is still glue in the glue pot, the equipment action control unit 33 controls the stop block to come down and prompts through the alarm device that the color of the current workpiece is inconsistent with the glue color used by the current system, and the glue pot residual glue needs to be cleaned before automatically switching the glue. When the glue pot residual glue needs to be cleaned, the equipment action control unit 33 controls the glue cleaning device to perform the glue cleaning operation. During the glue cleaning process, the glue amount detection sensor of the glue acts to monitor the glue cleaning situation in real time. After the glue cleaning is completed, the glue switching control unit 31 automatically switches to the mixing mode corresponding to the detected color for the glue application action, and at the same time eliminates the alarm prompt. The equipment action control unit 33 controls the upshift block to complete the glue switching, and then the glue application amount adjustment unit 32 accurately adjusts the glue application amount through the servo system. The equipment action control unit 33 controls the actions of components such as the edge banding machine stop block and glue cleaning to complete the glue matching and glue application operations. The monitoring module 4 compares the actual and set glue application amounts through the glue amount monitoring unit 41, and feeds back to the data processing module 2 when the deviation exceeds the range. The glue color is checked through the glue color monitoring unit 42, and an alarm is given and fed back to the data processing module 2 when the colors are inconsistent. The feedback control unit 24 of the data processing module 2 optimizes the control instruction according to the feedback data and sends it to the control execution module 3 for execution; among them, the color detection unit 11 triggers a detection once in the following situations: when there is already an edge band on the tape feeding platform at system startup, when changing batches and switching the edge band, when performing manual or automatic tape replacement, and when restarting after stopping processing midway. Without stopping the machine or changing the edge band, the color detection unit 11 does not perform a secondary measurement to avoid unnecessary detection and data processing and improve the system efficiency;In the color detection unit 11, one or a combination of a color code sensor 111, a photoelectric sensor 112, and an image recognition sub-unit 113 is used for color detection; the data interaction unit 51 in the expansion module 5 is responsible for data interaction with an external system such as an EMS system, and also shares data with the data processing module 2. The data interaction unit 51 uploads the production data inside the system, such as glue usage, processing quantity, etc., to the external system, and at the same time receives instructions such as production tasks and process parameters issued by the external system, and transfers these instructions to the data processing module 2, so that the system can adjust the working mode according to external requirements. The function expansion unit 52 works in cooperation with the detection module 1 by adding new function modules such as a scanning function. The information of the board and the edge banding obtained by scanning the code can be used as a supplement to the data collection of the detection module 1, further improving the recognition accuracy of the system for the processing object.
