Description

Technical Field

[0001] This utility model relates to production line measuring equipment, and more particularly to production line measuring equipment for woodworking edge banding production systems. Furthermore, this utility model also relates to a woodworking edge banding production system employing such production line measuring equipment. Background Technology

[0002] The woodworking edge banding production system is a mechanical processing equipment for edge banding furniture boards. The edge banding process usually includes multiple steps such as conveying, gluing and applying edge banding, cutting, front and back trimming, top and bottom trimming, top and bottom fine trimming, top and bottom scraping, and polishing. The automated woodworking edge banding production system is fully automated, with automated processing equipment at different processing stations performing processing operations in sequence. As the conveyor belt runs, the template to be processed goes through different processing steps.

[0003] To determine when to start the processing equipment, the real-time position of the wood board to be processed needs to be compared with the position of the processing station. The position of the wood board is dynamic data and needs to be detected in real time, while the position of the processing station is relatively fixed preset data, which is determined when the woodworking edge banding production system is installed and established, and needs to be obtained through actual measurement.

[0004] The actual location information of each processing station in the existing woodworking risk production line is obtained through manual measurement. Manual measurement is limited by the operator's skill level, resulting in a large rate of random error and relatively low efficiency. The measurement results after measuring each processing machine also need to be manually entered. Due to the large number of stations, the entry time is long and the operation is cumbersome, further increasing the probability of random errors.

[0005] Therefore, a solution that minimizes measurement errors and efficiently records data is a pressing technical problem that needs to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide a production line measuring device for a woodworking edge banding production system. This device measures the position of each processing station in the system with high precision and automatically records and summarizes the measurement results. The production line measuring device includes a straight conveyor belt and multiple processing stations arranged along the same side of the conveyor belt. The device includes a ranging device and at least two target devices. The target devices are positioned at each processing station. Optical baffles on each target device are at the same height as the conveyor belt. The optical baffles are vertically arranged in a straight line. The ranging device is located at the end of the straight line and measures the distance from each optical baffle to itself. The measurement results characterize the position information of each processing station.

[0007] Preferably, the target device further includes a telescopic mechanism, on which the optical baffle is disposed and moves away from or into the linear queue under its control.

[0008] Preferably, the telescopic mechanism is a linear cylinder, the end of which is fixed to the optical baffle. The optical baffle extends as the linear cylinder extends and retracts as the linear cylinder retracts.

[0009] Preferably, the ranging device is a laser rangefinder, and the measuring optical path of the laser rangefinder coincides with the linear array.

[0010] Preferably, the production line measuring equipment further includes a control unit, which is connected to each of the target devices via a control line and to the ranging device via a data line. The control unit controls the position of the optical baffle of each of the target devices via the control line and obtains the distance parameters of the ranging device via the data line.

[0011] Preferably, the control unit further includes a storage element and a data output. The storage element is used to store the distance parameters acquired by the control unit, and the data output is electrically connected to the storage element.

[0012] The purpose of this utility model is also to provide a woodworking edge banding production system, including a straight conveyor belt and multiple processing stations arranged along the same side of the conveyor belt, and also including the above-mentioned production line measuring equipment, wherein the target device is set at the same position on each of the processing stations.

[0013] Preferably, the drive motor of the conveyor belt has an encoder for measuring the rotation angle, and the woodworking edge banding production system further includes a wood board position calculation unit. The wood board position calculation unit processes the measurement results of the encoder to obtain the actual position of the wood board to be processed on the conveyor belt.

[0017] Label Explanation

[0018] 10 conveyor 11 Processing station 12 Pressure beam 20 Distance measuring device 30 Target device 31 linear cylinder 32 Optical baffle 40 Control Unit 41 Control circuit 42 Data lines 43 storage element 44 Data export Detailed Implementation

[0019] The specific embodiments of this utility model will be described below with reference to the accompanying drawings.

[0020] Figure 1 A woodworking edge banding production system and its production line measuring equipment are demonstrated. The woodworking edge banding production system includes a straight conveyor belt 10. The wood boards to be processed are placed on the conveyor belt 10 and held between the conveyor belt 10 and a pressure beam 12 positioned above it, thus ensuring stable linear movement as the conveyor belt 10 rotates. Multiple processing stations 11 are arranged sequentially on one side of the conveyor belt 10. In this embodiment, there are twenty processing stations 11, but this number can be increased or decreased depending on the production process requirements. The processing stations 11 are arranged in a straight line along one side of the conveyor belt 10, and each processing station 11 is equipped with corresponding processing equipment.

[0021] At the same height end of one side of the conveyor belt 10, a laser rangefinder is provided as a ranging device 20, and the measuring optical path of the laser rangefinder is parallel to the conveyor belt 10. At each processing station 11, a target device 30 is provided, and each target device 30 has an optical baffle 32, which is located on the measuring optical path and perpendicular to the measuring optical path of the laser rangefinder.

[0022] like Figure 2 As shown, each target device 30 further includes a linear cylinder 31, with an optical baffle 32 disposed at the end of the linear cylinder 31. The linear cylinder 31 controls the optical baffle 32 to move linearly along a straight line perpendicular to the measurement optical path. When all linear cylinders 31 are in the extended state, all the optical baffles 32 are arranged in a straight line, which coincides with the measurement optical path. When the linear cylinders 31 are in the retracted state, the optical baffles 32 leave the straight line.

[0023] The laser rangefinder always measures the distance between itself and the nearest optical baffle 32.

[0024] like Figure 3As shown, the production line measuring equipment in this embodiment also includes a control unit 40. The control unit 40 is connected to each of the target devices 30 via a control line 41 and to the laser rangefinder via a data line 42. The control unit 40 controls the operating state of the linear cylinders 31 of each target device 30 via the control line 41, thereby controlling the position of the optical baffle 32. The control unit 40 acquires the measurement results from the laser rangefinder via the data line 42. The control unit 40 also includes a storage element 43 for storing data received from the laser rangefinder. The control unit 40 further includes a data output 44, which is electrically connected to the storage element 43. The data output 44 can be a wired interface, such as a USB interface or a network cable interface, or a wireless interface, such as a Bluetooth interface or a wireless LAN adapter. External devices, such as industrial control tablets or industrial computers, read the data stored in the storage element 43 through the data output 44.

[0025] The operating mode of the production line measuring equipment in this embodiment is as follows:

[0026] S1: The control unit 40 sends a first control signal to all target devices 30 through the control line 41. The linear cylinder 31 of the target device 30 extends under the control of the first control signal, so that the optical baffle 32 set on it enters the linear queue.

[0027] S2: The laser rangefinder begins measuring the distance between itself and the nearest optical baffle 32, in order to Figure 2 For example, the distance between the target device 30 and the target device 30 set on the first processing station 11 is measured, and the measurement result is transmitted to the control unit 40 through the data line 42.

[0028] S3: The control unit 40 stores the measurement results corresponding to the first processing station 11 in the storage element 43 in a preset order, and then sends a second control signal to the target device 30 on the first processing station 11 through the control line 41. The linear cylinder 31 of the target device 30 retracts from the control line of the second control signal and leaves the linear queue.

[0029] Because the target device 30 at processing station 11 retracts, processing station 2, which is closest to the laser rangefinder in the straight line queue, repeats a process similar to S2 and S3 until the distance between the target at processing station 20 and the laser rangefinder is stored in the storage element 43. In this embodiment, the measurement results are stored in a data queue.

[0030] When it is necessary to read the measurement results, the external device establishes a data link through the data outlet 44, and then reads and uses the measurement results in the storage element 43 through the data outlet 44, thereby accurately obtaining the position parameters of each processing station 11 on the woodworking edge banding production system.

[0031] Another specific embodiment of the woodworking edge banding production system of this utility model yields the following results: Figure 1 As shown, it includes the aforementioned production line measuring equipment, and the drive motor of the conveyor belt 10 includes an encoder, which is used to measure the rotation angle of the corresponding drive motor. When the conveyor belt 10 is running, the actual position of the template to be processed can be obtained according to the output value of the encoder. When the actual position of the template to be processed matches the position of the corresponding processing station 11, it is determined that the template to be processed has moved to the appropriate position, and the processing station 11 automatically starts to perform the edge sealing process on the template to be processed.
