Description

Technical Field

[0001] This utility model relates to, but is not limited to, the technical field of gypsum board production equipment, and more specifically, to an automatic gypsum board polishing system. Background Technology

[0002] In the production of gypsum board, the cutting machine is one of the key pieces of equipment, used to cut continuously formed gypsum board into boards of specified lengths. However, in actual production, due to factors such as mechanical vibration, tool wear, and transmission system errors, the cut boards are prone to length deviations, resulting in boards that are slightly longer or shorter than intended. This length deviation not only affects the normal operation of the subsequent conveying system but may also cause malfunctions in the cutting and packaging equipment, reduce production efficiency, and even lead to equipment shutdowns and production interruptions.

[0003] Furthermore, during the molding and conveying process of gypsum board, external environmental factors (such as changes in temperature and humidity) or unstable equipment operation (such as conveyor belt slippage or uneven rollers) can affect the appearance quality of the boards, resulting in defects such as uneven surfaces, edge damage, and cracks. These appearance quality problems not only reduce the pass rate of the boards but may also lead to serious quality accidents, affecting the product's market competitiveness.

[0004] Currently, traditional gypsum board production lines mainly rely on manual inspection or simple sensor detection to identify defective boards. This method suffers from low detection efficiency, high false positive rate, and slow response speed, making it difficult to meet the requirements of modern production lines for high precision, high efficiency, and quality stability. Therefore, there is an urgent need for a technical solution that can accurately detect the length and appearance quality of boards in real time and automatically process defective boards to improve production efficiency, reduce scrap rate, and avoid production accidents caused by quality problems.

They are used together with the embodiments of this application to explain the technical solution of this utility model and do not constitute a limitation on the technical solution of this utility model.

[0015] Figure 2 This is a schematic diagram of the structure of an automatic plate-throwing system according to an embodiment of the present invention. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0017] In one embodiment of this utility model, as follows: Figure 1 and Figure 2 As shown, an automatic plate-throwing system is provided. This automatic plate-throwing system may include: a conveyor roller conveyor, detection equipment, a PLC, and a plate-throwing device;

[0018] The conveyor roller conveyor is configured to convey the plate material;

[0019] The detection device is configured to detect the board material and obtain a detection signal;

[0020] The PLC is configured to receive the detection signal and send an indication signal when it is determined from the detection signal that the plate needs to be thrown.

[0021] The plate-throwing device is configured to throw the currently conveyed plate after receiving the instruction signal.

[0022] The automatic plate-throwing system in this embodiment transports plates via a conveyor roller conveyor; a detection device inspects the plates and obtains a detection signal; a PLC receives the detection signal and, when it determines that plate-throwing is necessary based on the detection signal, sends an instruction signal; the plate-throwing device, upon receiving the instruction signal, throws the currently transported plates. This system, through the coordinated operation of the conveyor roller conveyor, detection device, PLC, and plate-throwing device, can detect plates and automatically handle defective plates based on the detection results, thereby improving production efficiency, reducing scrap rates, and preventing production accidents caused by quality issues.

[0023] Additionally, it should be noted that the PLC is also configured to execute the next process normally if it determines from the detection signal that the plate does not need to be discarded.

[0024] The plate ejection device may be, but is not limited to, a plate ejection device set on the conveyor roller, or a plate gripping device set near the conveyor roller, etc., and its function is to remove the plate located at a specific position on the roller from the roller.

[0025] In some exemplary embodiments, such as Figure 2 As shown, the detection device may include a laser ranging photoelectric sensor; the laser ranging photoelectric sensor is configured to illuminate the two sides and the top and bottom surfaces of the plate, and collect first data related to the size of the plate as the detection signal.

[0026] In some exemplary embodiments of this embodiment, the laser ranging photoelectric sensor may include a first laser ranging photoelectric sensor and a second laser ranging photoelectric sensor respectively installed on the left and right sides of the conveyor roller conveyor.

[0027] The first laser ranging photoelectric sensor is installed on the left side of the conveyor roller and is configured to measure a first distance from the first laser ranging photoelectric sensor to the left side of the plate, wherein the left side refers to the side of the plate that is close to the first laser ranging photoelectric sensor.

[0028] The second laser ranging photoelectric sensor is installed on the right side of the conveyor roller and is configured to measure the second distance from the second laser ranging photoelectric sensor to the right side of the plate, where the right side refers to the side of the plate that is close to the second laser ranging photoelectric sensor.

[0029] For example, the first data may include the first distance and the second distance, and the step of determining that the plate needs to be thrown based on the detection signal may include: calculating the width of the plate based on the first distance, the second distance and the first spacing, wherein the first spacing refers to the distance between the first laser ranging photoelectric sensor and the second laser ranging photoelectric sensor.

[0030] For example, the formula for calculating the width of the board material based on the first distance, the second distance, and the first spacing can be as follows: Board width = First spacing - First distance - Second distance.

[0031] The automatic plate-throwing system in this example uses a first laser ranging photoelectric sensor and a second laser ranging photoelectric sensor installed on the left and right sides of the conveyor rollers, respectively. These sensors measure the "first distance from the first laser ranging photoelectric sensor to the left side of the plate" and the "second distance from the second laser ranging photoelectric sensor to the right side of the plate." The first and second distances are then sent as detection signals to the PLC, which calculates the width of the plate. The PLC can then compare the real-time detected width of the plate with a preset standard width to monitor the quality of the plate (whether the width of the plate is up to standard). When the plate quality is not up to standard, an indication signal is output, and the plate-throwing device automatically throws the plate upon receiving the indication signal.

[0032] In some exemplary embodiments of this embodiment, the laser ranging photoelectric sensor may include a third laser ranging photoelectric sensor and a fourth laser ranging photoelectric sensor respectively installed on the upper and lower sides of the conveyor roller;

[0033] The third laser ranging photoelectric sensor is installed on the upper side of the conveyor roller and is configured to measure the third distance from the third laser ranging photoelectric sensor to the upper side of the plate, where the upper side refers to the side of the plate that is close to the third laser ranging photoelectric sensor.

[0034] The fourth laser ranging photoelectric sensor is installed on the lower side of the conveyor roller and is configured to measure the fourth distance from the fourth laser ranging photoelectric sensor to the lower side of the plate, where the lower side refers to the side of the plate that is close to the fourth laser ranging photoelectric sensor.

[0035] For example, the first data may include the third distance and the fourth distance, and the step of determining that plate throwing needs to be performed based on the detection signal may include: calculating the thickness of the plate based on the third distance, the fourth distance and the second spacing, wherein the second spacing refers to the distance between the third laser ranging photoelectric sensor and the fourth laser ranging photoelectric sensor.

[0036] For example, the formula for calculating the thickness of the plate based on the third distance, the fourth distance, and the second spacing can be as follows: Plate thickness = Second spacing - Third distance - Fourth distance.

[0037] The automatic plate-throwing system in this example uses a third laser ranging photoelectric sensor and a fourth laser ranging photoelectric sensor installed on the upper and lower sides of the conveyor rollers, respectively. These sensors measure the "third distance from the third laser ranging photoelectric sensor to the upper side of the plate" and the "fourth distance from the fourth laser ranging photoelectric sensor to the lower side of the plate." The third and fourth distances are sent as detection signals to the PLC, which then calculates the plate thickness. The PLC compares the real-time detected plate thickness with a preset standard thickness to monitor the plate quality (whether the plate thickness is up to standard). When the plate quality is not up to standard, an indication signal is output, and the plate-throwing device automatically throws the plate upon receiving the indication signal.

[0038] It should be noted that the automatic plate-throwing system of this embodiment can simultaneously install a first laser ranging photoelectric sensor, a second laser ranging photoelectric sensor, a third laser ranging photoelectric sensor, and a fourth laser ranging photoelectric sensor to achieve simultaneous monitoring of the plate width and thickness; alternatively, only the first laser ranging photoelectric sensor and the second laser ranging photoelectric sensor can be installed to monitor only the plate width; or alternatively, only the third laser ranging photoelectric sensor and the fourth laser ranging photoelectric sensor can be installed to monitor only the plate thickness.

[0039] In some exemplary embodiments, the automatic plate-throwing system may further include a servo motor (not shown in the figure); the servo motor is configured to drive the third laser ranging photoelectric sensor and the fourth laser ranging photoelectric sensor to move in the horizontal direction when the plate passes the third laser ranging photoelectric sensor and the fourth laser ranging photoelectric sensor.

[0040] For example, it can cruise continuously at a preset speed.

[0041] The automatic plate-throwing system in this embodiment uses a servo motor to drive the third and fourth laser ranging photoelectric sensors to move horizontally. This allows for comprehensive detection of the entire plate's thickness, providing better monitoring of plate quality. For example, it can measure whether the plate has dents or bulges.

[0042] In some exemplary embodiments, such as Figure 2 As shown, the detection device may include a through-beam photoelectric sensor installed on the side of the conveyor roller; the through-beam photoelectric sensor is configured to collect second data related to the flatness of the plate as the detection signal.

[0043] The automatic plate-throwing system in this embodiment can measure whether the plate is flat by using a through-beam photoelectric sensor installed on the side of the conveyor roller, thus enabling monitoring of the plate's flatness. For example, it can easily measure whether there are any protrusions on the plate.

[0044] In some examples of this embodiment, the through-beam photoelectric sensor may be located at the intersection of the solidification belt and the conveyor rollers.

[0045] The automatic plate-throwing system in this example, by placing a photoelectric sensor at the intersection of the solidification belt and the conveyor rollers, can detect the flatness of the plate after it has solidified, and detect whether the plate is flat as early as possible. If the plate is not flat, it can be directly judged as unqualified and automatically thrown.

[0046] In some exemplary embodiments, the through-beam photoelectric sensor can be installed in front of the laser rangefinder photoelectric sensor, that is, the through-beam photoelectric sensor is used first to monitor the flatness of the board. In this way, once the PLC finds that the flatness of the board is not up to standard, it can directly determine that the current board is unqualified, without having to judge the width and thickness of the board.

[0047] In some exemplary embodiments, such as Figure 2 As shown, the automatic plate-throwing system may further include an inkjet printer installed above the conveyor rollers; the inkjet printer is configured to lift the printhead cylinder of the inkjet printer when it receives the instruction signal.

[0048] The automatic plate-throwing system in this embodiment uses a PLC to control the inkjet printer above the conveyor rollers. When the plate is unqualified, the inkjet printer's printhead cylinder is raised to prevent the unqualified plate from being printed, thus achieving automatic control of the printing.

[0049] In some examples of this embodiment, the PLC can also be configured to: after detecting that the board material is unqualified, continue to monitor whether the board material is qualified; once the board material is detected as qualified and this continues for a first preset time, stop outputting the indication signal (the "indication signal" appearing alone in this application refers only to the indication signal of unqualified board material), and output a qualified indication signal instead. The inkjet printer is configured to raise or lower the printhead cylinder of the inkjet printer when it receives the qualified indication signal.

[0050] For example, the first preset duration can be 5 seconds, but other values ​​can also be set according to the actual situation.

[0051] The automatic plate-throwing system in this embodiment uses a PLC to control the inkjet printer above the conveyor rollers, thus achieving automatic control of inkjet printing and stopping inkjet printing.

[0052] Furthermore, as can be seen from this embodiment, the PLC operates in three ways: First, when the PLC detects that the board material is unqualified based on the detection signal and determines that it needs to be discarded, it outputs an indication signal to control the discarding device to discard the board. Second, during the automatic discarding process after detecting that the board material is unqualified, the PLC does not immediately output a qualified indication signal when it detects that the board material is qualified. Instead, it outputs a qualified indication signal only after continuously detecting that the board material is qualified for a first preset time, prompting the operator to stop the discarding device or automatically controlling the discarding device to stop discarding the board. Third, when discarding is not being performed (i.e., the board material is in the qualified process), if the PLC detects that the board material is still qualified based on the detection signal, it proceeds with the current process normally.

[0053] In some exemplary embodiments, such as Figure 2 As shown, the automatic plate-throwing system may further include a human-machine interface; the human-machine interface is used to display signals output by the PLC.

[0054] For example, the human-machine interface can display the width and thickness values ​​of the board; and, when receiving the qualified indication signal, provide a prompt so that the operator can close the automatic board-throwing program according to the on-site situation when the board is restored from unqualified to qualified.

[0055] The automatic plate-throwing system in this embodiment can display the width and thickness values ​​of the plate through a human-machine interface, allowing staff to view the plate data in real time.

[0056] In some exemplary embodiments, such as Figure 2 As shown, the automatic plate-throwing system may further include a cutting machine; the cutting machine is used to cut the plate according to a preset length.

[0057] The automatic slab cutting system of this embodiment can directly cut continuously formed gypsum boards into boards of specified lengths after the boards have passed the inspection, so as to meet the needs of subsequent processing, packaging and transportation.

[0058] In summary, the automatic plate-throwing system of this application can greatly reduce the labor intensity of employees, detect plate abnormalities in the first instance, and detect the geometric dimensions of the plate in real time, thereby improving the product qualification rate.
