[0049] Figure 1 is an optional flowchart of the production control method for post-loading of an electronic saw provided by an embodiment of the present invention, Figure 1 The method in may include but is not limited to steps S100 to S300.

[0050] S100. Obtain a production task, and based on the production task, obtain a first pallet stack and place it at a first buffer position;

[0051] wherein, the production task includes the pallet stack type, the pallet stack number, and the number of pallet stacks;

[0052] It should be noted that in some embodiments, step S100 may include the following steps: obtain a production task from a warehouse management system through a stacker, and based on the pallet stack number and the number of pallet stacks, obtain a first pallet stack through the stacker and place it at a first buffer position.

[0053] Among them, in some embodiments, obtaining a production task from a warehouse management system through a stacker, and obtaining a first stack of boards and placing it in a first cache position based on the stack number and the number of stacks of boards through the stacker can include the following steps: sending a task application to the warehouse management system through the stacker based on a preset communication protocol; adjusting the second identification number of the warehouse management system to be the same as the first identification number of the stacker; when there is a production task in the warehouse management system, passing the production task to the stacker through the warehouse management system in response to the task application; otherwise, adjusting the second identification number of the warehouse management system to be the same as the first identification number of the stacker, and after a preset interval, returning to execute the step of sending a task application to the warehouse management system through the stacker based on the preset communication protocol; taking out the first stack of boards from a designated storage location through the stacker based on the stack number and the number of stacks of boards, and then placing the first stack of boards in the first cache position; adding 1 to the first identification number of the stacker, and returning to execute the step of sending a task application to the warehouse management system through the stacker based on the preset communication protocol.

[0054] For example, in some specific implementations, the stacker is a device for picking up and placing goods in a vertical warehouse, and can take out goods from a specified location in the warehouse and place them at a specified exit, or deliver goods from a fixed entrance to a specified location according to task instructions. Specifically:

[0055] The stacker can use PLC (Programmable Logic Controller), so the task information transmission between WMS (Warehouse Management System) and the stacker can be exchanged through the S7 communication protocol. When the equipment is in normal state and there is no task, the stacker will send an idle task request to the WMS system. Both parties use the method of comparing the two numbers to confirm whether the interaction signal is received. For example, the number written by PLC is 2, and the number written by WMS is 1. PLC is 1 larger than WMS, which means that WMS receives the interaction request and starts to find out whether there is a task in the system database. If there is a task, the task data will be passed to PLC, and the number of WMS will be changed to be consistent with PLC to confirm that the interaction is completed. PLC will execute the task, and after the execution is completed, it will add 1 to the number and apply for a new task. If WMS receives the interaction signal and there is no task, it will also change the number to be consistent with PLC. PLC without task will initiate a new task application after an interval of 3 seconds. This is for both parties to confirm that the communication with each other is normal.

[0056] S200, obtaining the state of the second cache bit of each electronic saw, and responding to the material request of the target electronic saw based on the state;

[0057] Among them, states include idle, occupied, and allocated;

[0058] It should be noted that in some embodiments, step S200 may include the following steps: obtaining the number of electronic saws with the status of the second cache bit being idle; taking the electronic saw with the largest number of idle second cache bits as the target electronic saw; obtaining and responding to the material request of the target electronic saw.

[0059] Among them, in some embodiments, the method further includes the following steps: when the number of idle second cache bits of all electronic saws is the same, taking the electronic saw farthest from the first cache bit as the target electronic saw.

[0060] Exemplarily, in some specific embodiments, it is necessary to distinguish two types of devices here, the pusher and the electronic saw. Taking the number of pushers as two, namely 1# and 2#, and the electronic saws including six electronic saws numbered 1 - 6# as an example: The pusher and the electronic saw are not fixedly paired, and both pushers can push the board to the 1 - 6# electronic saws. The status of the buffer station in the system can be updated in real time according to the signal of whether there is a board collected from the PLC. The pusher divides the board according to the number of buffer stations that each cutting saw can hold. The system has three settings for the status of the buffer station: idle, allocated, and occupied. Idle means empty, allocated means that the pusher has already divided one board to this buffer bit, but it is still on the conveying path at that time, and occupied means that the board that was just allocated but not yet arrived has now arrived. Only when there is an idle buffer bit can the pusher divide the board to the electronic saw.

[0061] For example, if the 1# electronic saw has a total of 3 buffer stations and 1 of them has a board, the available buffer quantity is 2. If the 2# electronic saw has a total of 3 buffer stations and none of them have a board, the available buffer quantity is 3. If the 6# electronic saw has a total of 2 buffer stations and none of them have a board, the available buffer quantity is 2. When the pusher distributes the board, under the same conditions, it will give priority to the device with a larger serial number because the larger the device serial number, the farther it is from the pusher. To ensure the balance of the workload, the farther one is given priority for distribution. In addition, it will also be calculated according to the available buffer quantity. If the available buffer quantity of the 1# electronic saw is 3 and that of the 5# electronic saw is 2, then it will be distributed to the 3#

[0062] The distribution situation of the electronic saw and the pusher is that the larger the serial number of the electronic saw, the farther it is from the pusher. Considering the balance of the output of each electronic saw, the board - dividing principle is to go from far to near first. Simply put, everyone should have work to do.

[0063] When all the buffer positions of the electronic saws are empty, the No. 6 electronic saw first takes one board, and then during the conveying process, the pusher gives one board to the No. 5 pusher, then one board to the No. 4 pusher. Then, since the No. 6 electronic saw is farther away and the No. 4 electronic saw is closer, so everyone can receive the board for production work almost at the same time. Another situation is that when all the buffers of the No. 4 electronic saw are empty and there is already one board in the buffer of the No. 6 electronic saw, the principle of giving priority to the farther one first and then the closer one cannot take effect. The No. 4 machine has no work to do, and one board must be given to the No. 4 machine to work first.

[0064] S300. Based on the material requirement application of the target electronic saw, the second pallet is taken from the first buffer position by the pusher and sent to the target second buffer position of the target electronic saw for cutting processing.

[0065] It should be noted that in some embodiments, the number of pushers is at least two, at least one is used as the working pusher, and at least one is used as the standby pusher; step S300 may include the following steps: based on the material requirement application of the target electronic saw, adjust the state of the target second buffer position of the target electronic saw to allocated, take the first preset number of pallets from the first buffer position by the working pusher and send them to the target second buffer position of the target electronic saw, adjust the state of the target second buffer position to occupied, perform cutting processing by the target electronic saw in response to the cutting instruction, take the second preset number of pallets from the first buffer position by the standby pusher for standby; wherein, when the target electronic saw has completed the cutting processing on all the pallets in the target second buffer position, adjust the state of the target second buffer position to idle; when all the pallets in the working pusher have been sent to the target second buffer position, convert the working pusher and the standby pusher, and return to execute the step of obtaining the state of the second buffer position of each electronic saw and responding to the material requirement application of the target electronic saw based on the state.

[0066] Among them, in some embodiments, the number of pushers is at least two, at least one is used as the flexible line pusher, and at least one is used as the automatic line pusher; the pallet types include automatic line, when the pallet types also include flexible line, step S300 may include the following steps: when the material requirement application is generated based on the pallet type of the automatic line, based on the material requirement application of the first target electronic saw, take the third preset number of pallets from the first buffer position by the automatic line pusher and send them to the target second buffer position of the first target electronic saw for cutting processing; when the material requirement application is generated based on the pallet type of the flexible line, based on the material requirement application of the second target electronic saw, take the fourth preset number of pallets from the first buffer position by the flexible line pusher and send them to the target second buffer position of the second target electronic saw for cutting processing.

[0067] Exemplarily, in some specific embodiments, taking two pusher machines as an example: The working states of the pusher machines are two modes, namely, in use and standby. The working modes of the two pusher machines are one in use and one in standby, working alternately. One set is in use while the other is in standby. Until the pusher machine in use has finished pushing all the boards, the other pusher machine will switch to the in-use state to start pushing the boards. The original pusher machine that was pushing the boards will then start to load new boards and wait in standby. This is one situation. Another situation is that if there are production tasks on the flexible line in the production plan, then one of the two pusher machines will be responsible for the flexible line and the other will be responsible for the automatic line, and both will be in the in-use state simultaneously.

[0068] The blanking buffer station is configured with a corresponding number of blanking buffer stations (i.e., the second buffer positions) in the system according to the number of blanking buffer positions on-site. Specifically:

[0069] The buffer position (same as the second buffer position) is a term at the system level. In fact, it is a piece of equipment. Three buffer positions mean three conveying devices. Whatever equipment is on-site is fixed. The system only configures according to the on-site equipment layout. For example, if there are 3 pieces of equipment placed behind the No. 1 electronic saw, then the configured buffer quantity is 3. This configuration is to create a piece of data in the database. The No. 1 pusher machine is equipped with 3 buffer positions, and then 3 more pieces of data with buffer position numbers are added. Adding 3 buffer positions is to manage the state of the buffer positions. For example, if a board has been allocated to a buffer position, then the state of the buffer position is allocated. Then the system will also collect signals from the PLC (electrical) to determine whether there is a board in the buffer position. If there is a board, the state of the buffer position will be changed to occupied, and if there is no board, it will be changed to idle. Briefly speaking, it is like this. In fact, there is a set of logic for the actual program to change the state, and the logic is as follows:

[0070] The initial state of the buffer position is idle. When the pusher machine distributes a board to a buffer position, the state changes to allocated. At this time, although the signal collected from the PLC indicates that there is no board, the state remains allocated and will not change to idle until the allocated board arrives at the buffer position. When a signal indicating that there is a board is collected from the PLC, the state will change to occupied. Subsequently, the board enters the electronic saw for production. When a signal indicating that there is no board is collected from the PLC, the state will change to idle, and then it waits for the pusher machine to distribute the board.

[0071] It should be noted that when the stack type of boards also includes the flexible line, a specific electronic saw can be designated as a dedicated flexible line processing device. Usually, the electronic saw farthest away can be designated as the flexible line processing device. At this time, the material requisition application of this electronic device is only generated based on the stack type of the flexible line. Its state adjustment principle is similar to the first embodiment of step S300 and will not be elaborated here. And the other remaining electronic saws also refer to the relevant logic principles of the first embodiment for stack distribution processing.

[0072] To explain the principle of the technical solution of the present invention in detail, the overall process of the present invention will be described below in conjunction with some specific embodiments. It is easy to understand that the following is an explanation of the technical principle of the present invention and should not be regarded as a limitation of the present invention.

[0073] First of all, it should be noted that the present invention aims to provide a method for production feeding, pushing the board to the destination point, and feeding the electronic saw, forming a logistics control system for the solution knowledge base system to achieve an efficient and intelligent solution. One of the important highlights is the automatic splitting of the pallet according to the configuration rules and pushing the board to the electronic saw. Through innovative technical implementation, it can achieve the timeliness and real-time of production feeding, and reduce the production waiting time caused by the conveying duration.

[0074] The process principle of the technical solution of the present invention is realized as follows:

[0075] 1. Pallet application for the board splitting buffer position:

[0076] As Figure 2 shown, configuring the "platform" means configuring the platform number of the buffer station. The platform number is the unique number defined by the system for each station.

[0077] When calculating the electronic saw mode, obtain the electronic saw information saved in the database from the database, and judge whether there is an unproduced flexible line production plan in the production plan of the day. If there is, fix the electronic saw with the largest serial number as the flexible line production mode. The larger the serial number, the farther away from the pusher.

[0078] The MES production task is sent from the MES system to the database of this system through the WEB Api interface.

[0079] According to the electronic saw production mode calculated above, if the production mode of the electronic saw is the flexible line, obtain the production plan of the flexible line from the database, otherwise obtain the production plan of the automatic line.

[0080] Calculate the cacheable pallet. The record of the pallet leaving the buffer station - the record of the pallet applying for the buffer station + 2 sections of the buffer line body = the number of cacheable pallets.

[0081] There are two concepts here, the buffer station and the buffer line body. Actually, they are the same concept, just called differently from different perspectives. At the software system level, it is called the buffer station, and at the equipment level, it is the buffer line body. Actually, it is two chain machines. The record of the pallet applying for the buffer station is actually the number of pallets entering the buffer, and the record of leaving the buffer is the number of pallets leaving the two buffer stations. The difference between the two numbers is the number of pallets remaining in the buffer for the station. If the number of pallets leaving is 1 less than the number of pallets entering, then there is one pallet remaining in the buffer area, and the cacheable quantity is left with 1.

[0082] Applying for the plate stack to be shipped out is to call the interface of the WMS system, and WMS returns the plate stack to be shipped out task.

[0083] The interface parameters include panel level, required quantity, panel stack quantity, and panel batch. Panel batch is not mandatory. It will only be transmitted when the production plan specifies the batch to be used. If the interface call is successful, the panel stack number, storage location, and panel stack quantity to be shipped will be returned. If the interface call fails, the corresponding error message will be returned, such as: there is no suitable panel stack. If an error message is returned, an enterprise WeChat message will be sent to notify the production staff to handle it.

[0084] The calculation of the number of plates is to obtain the number of large plates in the outbound task returned by the WMS (Warehouse Management System).

[0085] A stacker is a device used to pick up and place goods in a vertical warehouse. It can take out goods from designated locations in the warehouse and place them at designated exits according to task instructions, or deliver goods to designated locations from fixed entrances.

[0086] The stacker uses Siemens PLC, so the task information transmission between WMS and the stacker is carried out through Siemens S7 communication protocol for data interaction. When the stacker is in normal equipment status and has no tasks, it will send an idle task request to the WMS system. Both parties use the method of comparing the two numbers to confirm whether the interaction signal has been received. For example, if the number written by PLC is 2 and the number written by WMS is 1, PLC is 1 larger than WMS, which means that WMS receives the interaction request and starts to look for tasks in the system database. If there are tasks, the task data will be passed to PLC, and the number of WMS will be changed to be consistent with PLC to confirm that the interaction is completed. PLC will execute the task, and after the execution is completed, it will add 1 to the number and apply for a new task. If WMS receives the interaction signal and there is no task, it will also change the number to be consistent with PLC. PLC without tasks will initiate a new task application after an interval of 3 seconds. This is done by both parties to confirm that the communication with each other is normal.

[0087] 2. Switching process of disassembly mode:

[0088] According to the current production tasks in the system, determine whether there is an unproduced flexible line production plan. If so, saw No. 6 should be set to flexible line mode.

[0089] There are two push plate machines in the system, and the working states of the push plate machines include two modes: use and standby.

[0090] The working mode of the two pusher machines is one in use and one in standby, taking turns to work. One set is in use while the other is in standby. Until the pusher machine in use has pushed all the boards, the other one will switch to the working state to start pushing the boards, and the original pusher machine will start feeding new boards and then wait in standby. This is one situation. Another situation is that if there is a winning task for the flexible line in the production plan, then one of the two pusher machines will be responsible for the flexible line and the other for the automatic line, and both will be in the working state at the same time.

[0091] To determine whether the pusher machine continues to push, the pusher machine needs to wait for the pallet stack to enter before pushing. During the waiting process, the system will detect whether the standby pusher machine is ready (the ready condition requires whether there is a board in the pusher machine and whether the pallet stack in the pusher machine belongs to the same batch as the pallet stack currently being produced). If the standby pusher machine is ready and the current pusher machine is waiting for the pallet stack to enter, then set the standby pusher machine as in use and the current pusher machine as standby. If the standby pusher machine is not ready, then the current pusher machine can continue to push (be in use).

[0092] There is an interface in the system to manage the pusher machines. On the interface, the pusher machines can be operated to be disabled or enabled. For a disabled pusher machine, the system will not send the pallet stack in. To determine whether the pusher machine is ready, it will judge whether the pusher machine is enabled, whether there is a pallet stack in the pusher machine, what color the pallet stack in the pusher machine is, which batch it belongs to, and whether the pallet stack of this batch and color can be produced currently. For example, if pusher machine No. 1 has a board and the production batch of the board inside belongs to batch A, but the system is currently producing batch B, then pusher machine No. 1 is not ready.

[0093] 3. Loading the pusher buffer position:

[0094] As Figure 4 shown, only pusher machines No. 1, 2, and 6 are electronic saws. There are electronic saws numbered 1 - 6, but only electronic saw No. 6 can process the boards for the flexible line.

[0095] Here, two types of equipment need to be distinguished, the pusher machine and the electronic saw. There are two pusher machines, No. 1 and No. 2; there are six electronic saws numbered 1 - 6. There is no fixed pairing between the pusher machines and the electronic saws. Both pusher machines can push the boards to the electronic saws numbered 1 - 6.

[0096] 4. The board - splitting process of the board - splitting machine:

[0097] As Figure 5 shown, the cutting stock buffer platform is configured with the corresponding number of cutting stock buffer platforms in the system according to the number of cutting stock buffer workstations on site.

[0098] The buffer station is a term at the system level. In fact, it is a piece of equipment. Three buffer stations mean three conveying devices. Whatever equipment there is on-site is fixed. The system is only configured according to the on-site equipment layout. For example, there are three pieces of equipment placed behind the No. 1 electronic saw. Then the configured buffer quantity is 3. This configuration is to create a piece of data in the database. The No. 1 pusher is equipped with 3 buffer positions, and then add 3 pieces of data with buffer position numbers. Adding 3 buffer positions is to manage the status of the buffer positions. For example, if a board has been distributed to a buffer position, then the status of the buffer position is "allocated". Then the system will also collect the signal of whether there is a board in the buffer position from the PLC (electrical). If there is a board, the status of the buffer position will be changed to "occupied", and if there is no board, it will be changed to "idle". Briefly speaking, it is like this. In fact, there is a set of logic for the actual program to change the status. The logic is as follows:

[0099] The initial status of the buffer position is "idle". When the pusher distributes a board to a buffer position, the status changes to "allocated". At this time, although the signal collected from the PLC indicates that there is no board, the status remains "allocated" and will not change to "idle" until the allocated board arrives at the buffer position. When the signal of having a board is collected from the PLC, the status will change to "occupied". Subsequently, the board enters the electronic saw for production. When the signal of no board is collected from the PLC, the status will change to "idle", and then it waits for the pusher to distribute the board.

[0100] The system updates the status of the buffer station in the system in real time according to the signal of whether there is a board in the buffer station collected from the PLC, and distributes the boards pushed by the pusher according to the number of buffer stations that each cutting saw can hold. The system has three settings for the status of the buffer station: "idle", "allocated", and "occupied". "Idle" means empty. "Allocated" means that the pusher has already distributed 1 board to this buffer position, but it is still on the conveying path. "Occupied" means that the board that was just allocated but not yet arrived has now arrived. Only when there is an idle buffer position can the pusher distribute the board to the electronic saw.

[0101] For example, the No. 1 electronic saw has a total of 3 buffer stations. If there is a board in 1 of the stations, the available buffer quantity is 2. The No. 2 electronic saw has a total of 3 buffer stations. If there is no board in all 3 stations, the available buffer quantity is 3. The No. 6 electronic saw has a total of 2 buffer stations. If there is no board in both stations, the available buffer quantity is 2. When the pusher distributes the boards, under the same conditions, it will give priority to the equipment with a larger serial number because the larger the equipment serial number, the farther it is from the pusher. To ensure the balance of the workload, the farther ones are given priority for distribution. In addition, it will also be calculated according to the available buffer quantity. If the available buffer quantity of the No. 1 electronic saw is 3 and that of the No. 5 electronic saw is 2, then it will be distributed to the No. 3.

[0102] Regarding the distribution of the electronic saws and the pusher, the larger the serial number of the electronic saw, the farther it is from the pusher. Considering the balance of the output of each electronic saw, the board distribution principle is to give priority to the farther ones first and then the nearer ones. Simply put, everyone should have work to do.

[0103] When all the buffer positions of the electronic saws are empty, the No. 6 electronic saw first distributes one board, and then during the conveying process, the pusher gives one board to the No. 5 pusher, then one board to the No. 4 pusher. Then, because the No. 6 electronic saw is farther away and the No. 4 electronic saw is closer, so everyone can receive the board for production work almost at the same time. Another situation is that when all the buffers of the No. 4 electronic saw are empty and there is already one board in the buffer of the No. 6 electronic saw, the principle of first far then near cannot take effect, and the No. 4 machine has no work to do, and one board must be distributed to the No. 4 machine for work first.

[0104] 5. The feeding process of the electronic saw is as Figure 6 shown.

[0105] Among them, exemplarily, in some specific embodiments, the overall implementation process of the electronic saw post-loading production control method can be as follows:

[0106] Production material requisition: The electronic saw actively initiates a material requisition application according to the production task.

[0107] The board splitting machine splits the board: The board is split according to the required quantity of the board in the sawing file.

[0108] Board conveying: The split boards are conveyed to the electronic saw.

[0109] Loading completed: After the board reaches the electronic saw, feedback information.

[0110] Cutting file: The sawing file is sent to the electronic saw.

[0111] Surplus board returned to the warehouse: The pallet of boards not used up by the board splitting mechanism is returned to the warehouse.

[0112] In summary, the present invention is a method for data management, monitoring, and real-time scheduling based on a large amount of business data, mainly for pallet splitting, board conveying, and surplus board returning to the warehouse according to the set rules. Specifically, by continuously improving the data rules and intelligent systems, it enables managers to discover problems more quickly, make timely adjustments, and avoid risks, rather than dealing with problems after they occur; it improves the situation before using this intelligent system, which mainly relied on internal personnel to actively conduct inspections, manual material preparation, and manual picking.
