Description

Technical Field

[0001] The present invention relates to the technical field of product material storage management, and in particular to a decorative panel storage detection device and a decorative panel storage method. Background Art

[0002] With the rapid development of the industry, the changes in the times and the environment, in order to reduce costs and increase efficiency, it is gradually developing towards intelligence. After the traditional artificial decorative panels are produced, the detection speed of some detection devices cannot keep up with the production and warehousing speed of the decorative panels, causing the detection link to become a bottleneck in the production process. For example, traditional manual detection or detection equipment based on a single sensor is inefficient when facing large quantities of decorative panels entering the warehouse, and cannot meet the needs of rapid turnover. In addition, the degree of automation of some equipment is not high, and there are many links that require manual intervention, such as sample placement, data recording and analysis, etc. This not only increases labor costs, but also easily leads to inaccurate test results due to human factors. Summary of the invention

[0003] In view of this, the present invention provides a decorative panel warehousing detection device and a decorative panel warehousing method to solve the problem of how to accurately detect the decorative panel material warehousing process and automatically put it into storage.

[0004] In a first aspect, the present invention provides a veneer panel storage detection device, comprising: a transport corridor detection device, a storage corridor detection device and a PLC controller, wherein:

[0005] The transport corridor detection device includes a plurality of node detection units, each of which is correspondingly arranged on a transport unit of the transport corridor, and is used to detect the state of the veneer material on the transport corridor and the relative position on the transport corridor, and send the detection result to the PLC controller;

[0006] The storage corridor detection device is arranged on the storage corridor, and is used to detect the material status of the decorative panels on the storage corridor, the relative position on the storage corridor, and the size information of the materials, and send the detection results to the PLC controller;

[0007] The PLC controller is used to forward the detection results generated by the transport corridor detection device and the storage corridor detection device to the equipment management system WCS for controlling the operation status of the transport corridor and the storage corridor.

[0008] The veneer warehousing detection device provided by the embodiment of the present invention can accurately detect the state and position of materials during transportation and warehousing, which helps to ensure the quality of veneer panels. Monitoring starts from the transportation link, reducing quality problems caused by improper transportation, and further inspections are carried out at the warehousing link to ensure that only qualified materials can be smoothly put into the warehouse, thereby improving the overall quality of the product; the PLC controller plays a key role in data transfer, forwarding the detection results of the transportation corridor detection device and the warehousing corridor detection device to the equipment management system WCS, so that the WCS can obtain detailed information about the materials in real time. This data sharing mechanism is conducive to the collaborative work of the entire system. The equipment management system WCS can accurately control the operating status of the transportation corridor and the warehousing corridor based on this information.

[0009] In an optional implementation, each node detection unit of the transport corridor detection device is provided with the same sensor, including:

[0010] The first state detection sensor is arranged at a preset position of the transport unit near the transport entrance end, and is used to detect whether there is a veneer material on the transport corridor and generate material state detection information;

[0011] A first deceleration trigger sensor is disposed at a first preset position before the transport unit approaches the end of the transport direction, and is used to detect whether the veneer material reaches a first preset distance before the end of the transport unit;

[0012] A first arrival detection sensor is disposed at a second preset position before the end of the transport unit close to the transport direction, and is used to detect whether the veneer material reaches a second preset distance before the end of the transport unit, and the second preset distance is smaller than the first preset distance;

[0013] The first offside detection sensor is arranged at the end of the transport unit in the transport direction of the transport corridor, and is used to detect whether the decorative panel material on the conveying device exceeds the end of the transport unit.

[0014] The embodiment of the present invention can make the transportation process of the decorative panel materials in the transportation corridor more efficient through the coordinated work of the above sensors. Accurate deceleration and in-place control can reduce the pause and adjustment time during transportation, so that the materials can smoothly reach the transportation end at a more reasonable speed and position, thereby improving the efficiency of the entire transportation process. The setting of sensors can effectively prevent unexpected situations during the transportation of materials and improve the safety of the transportation link.

[0015] In an optional implementation, the storage corridor detection device includes:

[0016] The second state detection sensor is arranged at a preset position of the storage corridor near the storage entrance end, and is used to detect whether there is a veneer material on the storage corridor and generate material state detection information;

[0017] A second deceleration trigger sensor is disposed at a third preset position before the end of the storage corridor near the transport direction, and is used to detect whether the veneer material reaches a third preset distance before the end of the storage corridor;

[0018] A second arrival detection sensor is arranged at a fourth preset position before the end of the storage corridor near the transport direction, and is used to detect whether the veneer material reaches a fourth preset distance before the end of the storage corridor, and the fourth preset distance is smaller than the third preset distance;

[0019] The second offside detection sensor is arranged at the end of the storage corridor in the transportation direction, and is used to detect whether the veneer material exceeds the end of the storage corridor;

[0020] The length detection sensor is set at the bottom of the storage corridor to detect the length of the veneer material;

[0021] Front and rear boundary detection sensors are set at preset positions on the front and rear sides of the storage corridor to detect whether the veneer material is tilted and crosses the boundary in the transportation direction during transportation;

[0022] Left and right boundary detection sensors are set at preset positions on both sides of the storage corridor to detect whether the veneer material is tilted and crosses the boundary perpendicular to the transportation direction during transportation;

[0023] The height sensor is installed at the end of the storage corridor and is used to detect the height information of the decorative panel materials.

[0024] The embodiment of the present invention can accurately monitor the material status through the storage corridor detection device to achieve accurate regulation of the material transportation speed. The boundary detection sensor can timely detect the inclination of the material in the transportation direction and perpendicular to the transportation direction. This helps to discover quality problems that may cause material damage or storage inconvenience in advance, and ensure that the decorative panel materials enter the storage link in good condition.

[0025] In an optional implementation, the distance between the length detection sensor and the second in-place detection sensor is determined according to the lengths of materials of different specifications.

[0026] Since the lengths of decorative panel materials of different specifications are different, the embodiment of the present invention determines the distance between the two according to their lengths, which can ensure that the length detection sensor detects the length of the material at the appropriate time, while avoiding premature or late detection due to unreasonable distance setting, thereby ensuring the accuracy of the detection data, and determining the specification of the material based on the location of the sensor and the detection results of the sensor.

[0027] In an optional embodiment, the first state detection sensor, the first deceleration trigger sensor, the first in-place detection sensor, the first offside detection sensor, the second state detection sensor, the second deceleration trigger sensor, the second in-place detection sensor, the second offside detection sensor, and the length detection sensor are all diffuse reflection photoelectric sensors.

[0028] As a non-contact sensor, the diffuse reflection photoelectric sensor will not make physical contact with the surface of the material when detecting the various states and sizes of the decorative panel material. This is crucial for products such as decorative panels that have high surface quality requirements, because it avoids physical damage such as scratches and collisions that may be caused by contact detection, ensuring that the appearance quality of the material is not affected, especially for some decorative panels with coated surfaces or high decorative requirements, which can effectively maintain their integrity; in addition, in the industrial environment of transportation and warehousing, there may be complex factors such as dust and light changes. The diffuse reflection photoelectric sensor can adapt to these environmental changes to a certain extent. As long as the reflection intensity of the light signal is within its detectable range, it can work normally. Compared with some sensors with strict environmental requirements, it has better robustness, reduces detection errors or failures caused by environmental factors, and ensures the continuity of detection work.

[0029] In an optional implementation, the front and rear boundary detection sensors and the left and right boundary detection sensors are all mirror reflection photoelectric sensors.

[0030] The mirror reflection photoelectric sensor has a high detection accuracy for the boundary. For the front and rear boundary detection sensors, it can accurately determine whether the decorative panel material exceeds the preset boundary range in the transportation direction; for the left and right boundary detection sensors, it can also accurately detect whether the material is tilted and crosses the boundary perpendicular to the transportation direction. This high-precision detection helps to timely detect the slight position deviation of the decorative panel during transportation, ensuring that the material is always on the correct transportation track, which is crucial to ensuring the quality of the material and smooth storage.

[0031] In an optional implementation, the PLC controller is used to forward the detection results generated by the transport corridor detection device and the storage corridor detection device to the equipment management system WCS to monitor the operation status of the transport corridor and the storage corridor, including:

[0032] When the PLC controller monitors the changes or abnormalities in the induction light sources received by the first state detection sensor and the second state detection sensor, it forwards the information to the equipment management system WCS to control the corresponding corridor motor to start running;

[0033] The PLC controller monitors the first state detection sensor and the second state detection sensor to detect changes or abnormalities in the light source, and when changes or abnormalities are detected in the light sources of the first deceleration trigger sensor and the second deceleration trigger sensor, the controller forwards the changes to the equipment management system WCS to control the corresponding corridor motor to decelerate and run;

[0034] The PLC controller monitors the first state detection sensor and the second state detection sensor to sense the change or abnormality of the light source reception, and when the first in-place detection sensor and the second in-place detection sensor sense the change or abnormality of the light source reception, forwards it to the equipment management system WCS to control the corresponding corridor motor to stop running;

[0035] The PLC controller monitors the first state detection sensor, the second state detection sensor, the sensing light source receiving change or abnormality, and the first offside detection sensor, the second offside detection sensor, the sensing light source receiving change or abnormality, and forwards it to the equipment management system WCS to control the storage corridor motor to stop running and send out an alarm signal;

[0036] When the PLC controller monitors that any of the sensing light sources of the left and right boundary detection sensors and the front and rear boundary detection sensors is blocked, it forwards the information to the equipment management system WCS to control the storage corridor motor to stop running and send out an alarm signal.

[0037] The PLC controller in the embodiment of the present invention serves as a bridge between the transport corridor detection device, the warehousing corridor detection device and the equipment management system WCS, integrating and forwarding the detection results of each sensor. This centralized data processing and transmission method enables the equipment management system WCS to fully and real-time understand the status of materials during transportation and warehousing, thereby achieving effective management and control of the entire logistics system, promoting the collaborative work between different equipment and systems, improving the overall coordination and stability of the system, enabling the entire system to adapt to various specifications of material transportation and warehousing scenarios, and improving adaptability and intelligence.

[0038] In an optional embodiment, the device further includes: a sensing device and a code scanning device, wherein:

[0039] The sensing device is arranged at the storage entrance to sense whether the veneer material has arrived at the storage entrance;

[0040] The barcode scanning device is used to scan and read the product barcode information of the veneer material located at the warehouse entrance.

[0041] The embodiment of the present invention can accurately determine whether the decorative panel material has arrived at the storage port through the sensing device. Based on this sensing, the subsequent scanning device and other storage operations can be automatically triggered, so that the entire storage process can be carried out in an orderly manner according to the arrival of the materials, avoiding the inaccuracy and delay of manual judgment of the material location, greatly improving the automation level of the storage process, allowing materials to enter the warehouse more quickly, and improving the overall storage efficiency.

[0042] In a second aspect, the present invention provides a method for detecting warehousing of decorative panels, comprising:

[0043] The manufacturing execution system MES generates the veneer material and the corresponding product barcode, and triggers the product transportation signal based on the consistent confirmation signal of the veneer material and the corresponding product barcode;

[0044] The transport corridor of the veneer warehousing detection device of the first aspect starts to transport the veneer material based on the product transport signal, and detects the veneer material based on the transport corridor detection device;

[0045] After the equipment management system WCS receives the product barcode information sensed by the sensing device at the entrance, it starts the imaging scanning device to read the product barcode information, and when the product barcode information is consistent with the completion data provided by the production execution system MES, it starts the entrance corridor detection device of the decorative panel entrance detection device described in the first aspect to detect the decorative panel material. After the detection is passed, the corresponding three-dimensional warehouse location is allocated based on the read product barcode information, and the barcode information is fed back to the warehouse management system WMS after the warehousing operation is completed. The warehouse management system WMS generates inventory information based on the barcode information for storage, and sends the inventory information to the production execution system MES at the same time.

[0046] The decorative panel entry inspection method provided by the embodiment of the present invention records and associates multiple links around the product barcode information in the whole process. Whether it is relevant data in the production link, inspection conditions during transportation, or inventory information after entry into the warehouse, they can all be traced through the barcode information. Once quality problems such as product problems occur, the situation of each link can be quickly traced back and the problem can be accurately located, which helps to improve the level of product quality control and the ability of enterprises to deal with quality problems.

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0052] In an embodiment of the present invention, a veneer panel storage detection device is provided. Figure 1 As shown, it includes: a transport corridor detection device, a storage corridor detection device and a PLC controller, such as Figure 2 The diagram shown is a schematic diagram of its application scenario. The transport corridor detection device is set on the transport corridor, and the storage corridor detection device is set on the storage corridor to detect the status of the veneer material production line after the finished product is completed during the transportation process. Specifically:

[0053] The transport corridor detection device includes a plurality of node detection units, each of which is correspondingly arranged on a transport unit of the transport corridor, and is used to detect the material state of the decorative panels on the transport corridor and the relative position on the transport corridor, and send the detection results to the PLC controller;

[0054] The storage corridor detection device is arranged on the storage corridor, and is used to detect the material status of the decorative panels on the storage corridor, the relative position on the storage corridor, and the size information of the materials, and sends the detection results to the PLC controller;

[0055] The PLC controller is used for forwarding the detection results generated by the transport corridor detection device and the warehousing corridor detection device to the equipment management system WCS for controlling the operating status of the transport corridor and the warehousing corridor.

[0056] The transport corridor detection device provided in the embodiment of the present invention can detect the status of the decorative panel material on the transport corridor, and the storage corridor detection device can not only detect the material status, but also obtain the material size information and barcode information, etc. Through the cooperation of the detection devices in different corridors, the multi-dimensional status and key attributes of the decorative panels from transportation to storage are fully detected, which helps to accurately grasp the material situation and avoid management errors caused by missing information.

[0057] The PLC controller acts as a transit hub, forwarding all kinds of test results generated by the transport corridor detection device and the storage corridor detection device to the equipment management system WCS to control the operation status of the transport corridor and the storage corridor. Once a certain link detects that there is an abnormality in the material (such as poor material status, inconsistent dimensions, etc.), the PLC controller and the equipment management system can take corresponding measures to adjust or process it in time to prevent the problem materials from entering the subsequent storage links and ensure the high-quality operation of the entire storage process, thereby realizing the seamless connection and collaborative work between the detection link and the overall equipment management system, which is conducive to creating an automated and intelligent veneer storage management process, reducing the uncertainty and errors caused by manual intervention, and improving storage efficiency and accuracy.

[0058] The transport corridor in the embodiment of the present invention is composed of multiple transport units. The length of each transport unit is determined according to the length of the decorative panel material, which is slightly longer than the length of the finished material. For example, the length of the finished product is 2 meters and the transport unit is 2.2 meters. A node detection unit is provided on each transport unit to detect the status of the decorative panel material cargo and its relative position on the transport corridor. Each node detection unit of the transport corridor detection device is provided with the same sensor.

[0059] In one embodiment, the sensors of the node detection units are all diffuse reflection photoelectric sensors, which integrate a transmitter and a receiver. The transmitter emits a light beam. When the light beam hits the surface of an object, part of the light beam will be diffusely reflected back by the surface of the object and received by the receiver. If the object blocks part of the light beam, the sensor can receive the changes in the reflected light beam, thereby determining the position, shape, color or motion state of the object.

[0060] In the embodiment of the present invention, the photoelectric sensor status of the node detection unit is: N means no material; 0 means material; 1 means running; 2 means stopping; 3 means ready for storage; 4 means normal; 5 means abnormal. There are two specifications of the veneer material, and its length and width parameters are: length 2440*width 1220, length 2800*width 1220, unit: cm. The sensor of each node detection unit, such as Figure 3 As shown, including:

[0061] The first status detection sensor is arranged at a preset position of the transport unit near the transport entrance end, and is used to detect whether there is a decorative panel material on the transport corridor and generate material status detection information; for example, it is installed 60 cm away from the transport entrance end of the transport corridor, and the sensing light source is normally received, the status is no material (N), and the corridor status is (2); if the sensing light source receives changes or abnormalities, the status is material (0), and the corridor status is (1), then the PLC controller forwards it to the equipment management system WCS to control the start-up of the transport corridor motor.

[0062] The first deceleration trigger sensor is arranged at the first preset position before the end of the transport unit near the transport direction, and is used to detect whether the decorative panel material reaches the first preset distance before the end of the transport unit; the first deceleration trigger sensor acts as a deceleration trigger switch, and is installed 40 cm before the end of each node detection unit. The right light source is directed to the left, and the sensing light source receives changes or abnormalities. The state is that there is material (0), and the corridor state is (1). The PLC controller forwards it to the equipment management system WCS to control the deceleration operation of the transport corridor motor.

[0063] The first in-place detection sensor is arranged at a second preset position before the end of the transport unit near the transport direction, and is used to detect whether the decorative panel material reaches a second preset distance before the end of the transport unit, and the second preset distance is smaller than the first preset distance; the first in-place detection sensor acts as a stop trigger switch and is installed 10 cm before the end of the corridor. The right light source is directed to the left, and the sensing light source receives changes or abnormalities. The state is that there is material (0), and the corridor state is (2). The PLC controller forwards it to the equipment management system WCS to control the transport corridor motor to stop running.

[0064] The first offside detection sensor is arranged at the end of the transport unit in the transport direction of the transport corridor, and is used to detect whether the decorative panel material on the transport device exceeds the end of the transport unit. The first offside detection sensor acts as a protection switch. It is installed at the end of the corridor, where the right light source shines to the left. When the sensing light source receives changes or abnormalities, the state is that there is material (0), and the corridor state is (2). The PLC controller forwards it to the equipment management system WCS to control the transport corridor motor to stop running and alarm.

[0065] The sensors in the storage corridor detection device in the embodiment of the present invention are all photoelectric sensors, and their detection states are: N means no material; 0 means material; 1 means running; 2 means stopped; 3 means storage is possible; 4 means normal; 5 means abnormal. Figure 3 As shown, the storage corridor detection device includes:

[0066] The second status detection sensor is set at a preset position near the entrance end of the storage corridor to detect whether there is a decorative panel material on the storage corridor and generate material status detection information; for example, it is installed 60 cm away from the transportation entrance end of the storage corridor. When the sensing light source receives normally, the status is no material (N) and the corridor status is (2); when the sensing light source receives changes or abnormalities, the status is material (0) and the corridor status is (1). At this time, the PLC controller forwards it to the equipment management system WCS to control the start-up of the storage corridor motor.

[0067] The second deceleration trigger sensor is arranged at the third preset position before the end of the storage corridor near the transport direction, and is used to detect whether the decorative panel material reaches the third preset distance before the end of the storage corridor; the second deceleration trigger sensor acts as a deceleration trigger switch, and is installed 40 cm before the end of the storage corridor. The right light source is directed to the left, and the sensing light source receives changes or abnormalities. The state is that there is material (0), and the corridor state is (1). The PLC controller forwards it to the equipment management system WCS to control the deceleration operation of the storage corridor motor.

[0068] The second in-place detection sensor is arranged at the fourth preset position before the end of the storage corridor near the transport direction, and is used to detect whether the decorative panel material reaches the fourth preset distance before the end of the storage corridor, and the fourth preset distance is smaller than the third preset distance; the second in-place detection sensor acts as a stop trigger switch and is installed 10 cm before the end of the corridor. The light source on the right is directed to the left, and the sensing light source receives changes or abnormalities. The state is that there is material (0), and the corridor state is (2). The PLC controller forwards it to the equipment management system WCS to control the storage corridor motor to stop running.

[0069] The second offside detection sensor is arranged at the end of the transport direction of the storage corridor to detect whether the decorative panel material exceeds the end of the storage corridor. The second offside detection sensor acts as a protection switch and is installed at the bottom right of the end of the storage corridor. The light source is directed to the left and the sensing light source receives changes or abnormalities. The status is that there is material (0) and the corridor status is (2). The PLC controller forwards it to the equipment management system WCS to control the storage corridor motor to stop running and alarm.

[0070] The length detection sensor is installed at the bottom of the storage corridor to detect the length of the decorative panel material. It is installed above the light source at the bottom of the corridor, 2750 cm away from the second in-place detection sensor. If the sensing light source receives the material normally, the material specification is 2440 length * 1220 width. If the sensing light source receives changes or abnormalities, the length specification is 2800 length * 1220 width.

[0071] Front and rear boundary detection sensors are set at preset positions on the front and rear sides of the storage corridor to detect whether the decorative panel materials are tilted or cross the boundary in the transportation direction during transportation; for example, mirror reflection photoelectric sensors are installed at the upper edges of the front and rear sides of the corridor to sense downward, and reflectors are installed below; if the sensing light source is normal, the corridor status is changed (4); if the sensing light source is blocked, the corridor status is changed (5), and the PLC controller forwards it to the equipment management system WCS to control the storage corridor motor to stop running and alarm.

[0072] The left and right boundary detection sensors are set at the preset positions on both sides of the storage corridor to detect whether the decorative panel materials are tilted and cross the boundary perpendicular to the transportation direction during transportation. For example, the mirror reflection photoelectric sensor is installed on the upper edge of the left and right sides of the entrance corridor to sense downward, and a reflector is installed below; if the sensing light source is normal, the corridor state is changed (4); if the sensing light source is blocked, the corridor state is changed (5), and the PLC controller forwards it to the equipment management system WCS to control the storage corridor motor to stop running and alarm.

[0073] The height sensor is installed at the end of the storage corridor to detect the height information of the veneer material. For example, it is installed on the left and right sides of the end of the corridor entrance. After receiving the detection command from WSC, the height detection is started. The measuring equipment calculates the obstructed height, and then subtracts the height of the material's pad cover (the pad cover is uniformly 18 cm / sheet) from the calculated height. WCS obtains this data and matches the height error with the number recognized by the code reader. The error does not exceed 2 cm. Otherwise, an error is reported, the corridor status is changed (5), an alarm is recorded, and the operation is stopped.

[0074] In one embodiment, the second state detection sensor, the second deceleration trigger sensor, the second in-position detection sensor, the second offside detection sensor, and the length detection sensor are all diffuse reflection photoelectric sensors that integrate a transmitter and a receiver. The transmitter emits a light beam, and when the light beam hits the surface of an object, part of the light beam will be diffusely reflected back by the surface of the object and received by the receiver. If the object blocks part of the light beam, the sensor can receive the change in the reflected light beam, thereby determining the position, shape, color or motion state of the object. As a non-contact sensor, the diffuse reflection photoelectric sensor will not physically contact the surface of the material when detecting various states and sizes of the veneer material. This is crucial for products such as decorative panels that require high surface quality, because it avoids physical damage such as scratches and collisions that may be caused by contact detection, ensuring that the appearance quality of the material is not affected, especially for some decorative panels with coated surfaces or high decorative requirements, which can effectively maintain their integrity; in addition, in industrial environments such as transportation and warehousing, there may be complex factors such as dust and light changes. Diffuse reflection photoelectric sensors can adapt to these environmental changes to a certain extent. As long as the reflection intensity of the light signal is within its detectable range, it can work normally, has better robustness, reduces detection errors or failures caused by environmental factors, and ensures the continuity of detection work.

[0075] The front and rear boundary detection sensors and the left and right boundary detection sensors are mirror reflection photoelectric sensors, which consist of a light emitter and a light receiver, with a reflector installed in front. The light emitted by the light emitter is reflected back by the reflector and received by the light receiver. When the light path is blocked by the detection object, the light receiver cannot receive the light, thereby triggering the change of the switch signal. The mirror reflection photoelectric sensor has a high detection accuracy for the boundary. For the front and rear boundary detection sensors, it can accurately determine whether the decorative panel material exceeds the preset boundary range in the transportation direction; for the left and right boundary detection sensors, it can also accurately detect whether the material is tilted and crosses the boundary perpendicular to the transportation direction. This high-precision detection helps to timely detect the slight position deviation of the decorative panel during transportation, ensuring that the material is always on the correct transportation track, which is crucial to ensuring the quality of the material and smooth warehousing.

[0076] The height measuring device consists of two parts: a transmitter and a receiver. The transmitter emits infrared light or laser beams, and the receiver is responsible for capturing these beams. When an object passes through the beam, it will block part of the light. The receiver detects the change in light and calculates the height of the material by calculating the blocked beam. It has a fast measurement speed and can detect the change in light and calculate the height in real time when the decorative panel passes through the beam quickly. For the situation of large quantities of decorative panels entering the warehouse, the measurement work can be completed quickly, which greatly improves the efficiency of warehouse inspection.

[0077] The warehousing detection device provided by the embodiment of the present invention further includes a sensing device and a scanning device, wherein: the sensing device is arranged at the warehousing entrance, and is used to sense whether the veneer material has arrived at the warehousing entrance; the scanning device is used to scan and read the product barcode information of the veneer material located at the warehousing entrance. The sensing device can be an infrared sensing sensor, which senses the veneer material at the warehousing entrance, and can accurately determine whether the material has arrived at the specified position. Based on this sensing, the subsequent scanning device and other warehousing operations (such as starting the warehousing corridor detection device) can be automatically triggered, so that the entire warehousing process can be carried out in an orderly manner according to the arrival of the materials, avoiding the inaccuracy and delay of manual judgment of the material position, and improving the automation and efficiency of the warehousing process. After the sensing device determines that the material has arrived at the warehousing entrance, the scanning device starts to work to read the product barcode information, ensuring that the reading of the barcode information is carried out at the appropriate time and location, avoiding the situation where the information is inaccurate or does not match the actual material due to reading too early or too late, and ensuring that the collected barcode information accurately corresponds to the veneer material that is currently being stored.

[0078] The embodiment of the present invention also provides a method for storing decorative panels, comprising the following steps:

[0079] S1, the production execution system MES generates the veneer material and the corresponding product barcode, and triggers the product transportation signal based on the consistent confirmation signal of the veneer material and the corresponding product barcode.

[0080] Specifically, after the finished product is produced, the MES passes through, packages, and prints the barcode of the finished product, and after manually confirming that the barcode is correct with the actual product, the "conveyor corridor" start button is pressed to trigger the product transportation signal. The MES generates the veneer material and the corresponding product barcode, and relies on the consistent confirmation signal of the two to trigger the product transportation signal. In this way, a close connection between the material and the barcode is established from the source, which guarantees the accurate correspondence between the material and the corresponding identification information to the greatest extent, avoiding errors in the subsequent process due to confusion in identification, and laying the foundation for the precise operation of the entire logistics and warehousing links.

[0081] S2, the transport corridor starts to transport the decorative panel materials based on the product transport signal, and inspects the decorative panel materials based on the transport corridor detection device in the decorative panel warehousing detection device.

[0082] Specifically, in the embodiment of the present invention, during the transportation of decorative panel materials, the transportation corridor detection device detects the decorative panel materials, and can grasp the status of the materials in the transportation stage in real time. This synchronous detection method during transportation ensures that the materials can enter the transportation stage in time according to the plan after production is completed, avoiding the disruption of production rhythm caused by transportation delays, and ensuring the efficient operation of the entire production supply chain.

[0083] S3, after the equipment management system WCS receives the veneer material at the entrance through the sensing device, it starts the imaging scanning device to read the product barcode information, and when the product barcode information is consistent with the completion data provided by the production execution system MES, it starts the veneer entry corridor detection device in the veneer entry detection device to detect the veneer material. After the detection is passed, the corresponding three-dimensional warehouse location is allocated based on the read product barcode information, and the barcode information is fed back to the warehouse management system WMS after the warehousing operation is completed. The warehouse management system WMS generates inventory information based on the barcode information for storage, and sends the inventory information to the production execution system MES at the same time.

[0084] In one embodiment, product barcode information includes: ID, sales order, production order, order line number, finished product barcode, material code, material name, material specification, quantity, unit, quality grade, workshop name, equipment name, whether to enter the warehouse, shift, team, completion worker, completion time, material classification, customer name, production scheduling date, and remarks; inventory information includes: ID, warehouse area name, sub-warehouse name, warehouse location code, warehouse location type, sales order, production order, order line number, material barcode, material code, material name, material specification, material type, total quantity, available quantity, unit, customer name, production date, production batch, quality grade, warehouse entry time, static warehouse age, dynamic warehouse age, operator, inspector, inventory status, workshop name, equipment name, shift, team, completion worker, completion time, and remarks. The above is only for example description and is not limited to this.

[0085] In the embodiment of the present invention, the product barcode information is detected and checked based on different conditions (such as transportation corridor detection, scanning code verification at the entrance to the warehouse, etc.) in multiple links such as the transportation corridor and the storage corridor, and compared with the completion data provided by the production execution system MES. The multiple verification mechanism ensures the consistency of the product barcode information at different stages, greatly reducing the probability of problems such as chaotic inventory management and difficulty in product traceability caused by inconsistent data. After the detection is passed, the equipment management system WCS allocates the corresponding three-dimensional warehouse location based on the read product barcode information. This allocation method based on accurate product identification can achieve a more reasonable and accurate inventory layout, facilitate subsequent search, retrieval and inventory operations, and improve the utilization rate of storage space and the convenience of storage management. The warehouse management system WMS generates inventory information based on barcode information for storage, and promptly feeds back the inventory information to the production execution system MES, so that the production end can grasp the inventory situation in real time, facilitate the reasonable arrangement of subsequent production plans, avoid the situation of disconnection between production and inventory, and ensure the smooth and orderly development of the entire production operation activities.

[0086] The decorative panel entry inspection method provided by the embodiment of the present invention records and associates multiple links around the product barcode information in the whole process. Whether it is relevant data in the production link, inspection conditions during transportation, or inventory information after entry into the warehouse, they can all be traced through the barcode information. Once quality problems such as product problems occur, the situation of each link can be quickly traced back and the problem can be accurately located, which helps to improve the level of product quality control and the ability of enterprises to deal with quality problems.

[0087] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
