Description

Technical Field

[0001] The present invention relates to the technical field of mold processing, and in particular to an automated line material handling scheduling method based on a mold MES production plan. Background Art

[0002] The mold industry often produces small batches and multiple varieties, which requires flexible production management and scheduling. In order to improve production efficiency and precision, the mold industry is gradually adopting advanced technologies and management systems such as automated production lines, CNC machining centers, robots, and MES. A lot of materials are used in the mold manufacturing process. During the implementation process, the automated line material handling will be combined with AGV to effectively improve material handling efficiency, reduce dependence on manual labor, reduce safety hazards in manual operations, and improve the safety level of the working environment.

[0003] The mold industry belongs to a typical discrete processing mode, which is different from the batch processing mode of the batch industry according to a fixed process route. The processing routes of different materials under the mold are inconsistent. The production and processing plans of thousands of processes need to be arranged on site. Different materials use different materials. The automated lines on site in the workshop need to be produced and processed according to the processing plan. Before processing, it is necessary to ensure that the materials can be transported in advance. Different production sections will use different automated line units. The same material processing will have multiple processes. Multiple process processing involves one or more automated lines. There will also be coordination of material transfer between multiple lines. Material handling is a very important link in the production and processing of automated lines in the workshop. When multiple production and processing tasks are carried out in parallel, the scheduling plan of AGV handling tasks plays a key role.

[0004] AGV material handling requires solving the following problems: 1. How can the automated production line automatically call for materials according to the production plan requirements? 2. When multiple production lines call for materials at the same time, how should the AGV handle the materials? How to reasonably arrange the handling priorities to ensure the processing efficiency of the production line? 3. When the same material involves multiple production lines, how to effectively optimize the AGV handling route?

[0005] In response to the above problems, most of the current methods use manual methods to call AGV to transport materials (or manually operate the transportation), and the starting and end points of the transportation are manually given and then the AGV carries out the transportation, thereby achieving the purpose of material flow processing. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an automated line material handling scheduling method based on mold MES production plan, which can reduce on-site waiting and repeated handling.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: an automated line material handling scheduling method based on mold MES production plan, comprising: Obtain the production and processing plan of the MES system in real time and send it to the warehouse and various automated lines; When a pre-adjustment completed material handling request and a loading request are received, a loading and handling task is generated and sent to the AGV, and the destination in the loading and handling task is the loading docking station of the automated line that issued the loading request for the automated line; when only a pre-adjustment completed material handling request is received without a loading request, a loading and handling task is generated and sent to the AGV, and the destination of the loading and handling task is the off-line warehouse; when only a loading request is received without a pre-adjustment completed material handling request, a loading and handling task is generated and sent to the AGV, and the starting point in the loading and handling task is the off-line warehouse; When receiving a material unloading request, a material unloading and handling task is generated and sent to the AGV. At the same time, the automated line corresponding to the planned processing resources of the next processing task is obtained according to the material process route, and a query is sent to it whether to accept the material; when receiving a reply that the material can be accepted, the destination in the material unloading and handling task is set to the automated line that replied; when receiving a reply that the material cannot be accepted at the current time or no reply is received within a certain period of time, the destination in the material unloading and handling task is set to the off-line warehouse; Receive real-time feedback from AGV on the AGV position and handling status, and update the status and location of each material; The request for handling materials after pre-adjustment is initiated by the warehouse after material preparation and pre-adjustment; the request for loading materials is actively initiated by the automated lines in sequence according to the time sequence in their respective production and processing plans; the request for unloading materials is actively initiated by each automated line according to the processing status of its own materials, for materials that have been processed; the reply is sent by the automated line that receives the inquiry after judging based on the current situation.

[0008] According to the above scheme, when multiple transport requests are received, the transport tasks of the AGV are generated according to the preset priority and the time of the production and processing plan, and the AGV transports in sequence according to the time sequence of the transport tasks; The handling request includes a pre-adjustment material handling request, a loading request and a unloading request; The handling tasks include loading and unloading handling tasks; The principle of priority is: give priority to the unloading request of the automation line, and then consider the loading request.

[0009] According to the above scheme, the priorities are as follows: In order of priority from high to low, they are: unloading and handling tasks with the destination being the automated line, unloading and handling tasks with the destination being the off-line warehouse, loading and handling tasks, and other handling tasks.

[0010] According to the above scheme, the other handling tasks include: handling tasks called by humans.

[0011] According to the above scheme, the production and processing plan includes material information and process route.

[0012] According to the above scheme, the pre-adjustment completes the material handling request and the warehouse prepares the materials according to the production and processing plan. The warehouse personnel calls the AGV to transport the materials to the on-site pre-adjustment table. After the on-site fitter binds the chip to the material to mainly identify the identity of the parts to be processed, the on-site fitter confirms the initiation.

[0013] According to the above scheme, the off-line warehouse is a shelf outside the line of the workshop.

[0014] As a second aspect of the present invention, the present invention further provides a scheduling platform, comprising a data processing unit and a data transceiver unit connected to each other, wherein: The data transceiver unit is connected to the MES system, the automation line and the AGV system through the network to exchange data; The data processing unit is called to complete the automated line material handling scheduling method based on the mold MES production plan.

[0015] As a third aspect of the present invention, the present invention further provides an automated line material handling system based on mold MES production planning, comprising the scheduling platform, and an MES system, an automated line and an AGV system respectively connected to the scheduling platform via a network; wherein, The MES system schedules according to resource load conditions and generates a production and processing plan for each processing task; The scheduling platform obtains the production and processing plan in real time and distributes it to the warehouse and each automated production line; When the warehouse has prepared materials and completed pre-adjustment, humans proactively initiate pre-adjustment to complete the material handling request; When the automated production line receives the current production and processing plan, it will proactively initiate material loading requests in the order of the planned time, and proactively initiate material unloading requests for processed materials. When receiving an inquiry on whether to accept the material, it will send a reply based on the current situation. When the scheduling platform receives the pre-adjustment completed material handling request and the loading request, a loading and handling task is generated, and the destination in the loading and handling task is the loading docking station of the automated line that issued the automated line loading request; when the scheduling platform only receives the pre-adjustment completed material handling request and no loading request, a loading and handling task is generated, and the destination of the loading and handling task is the off-line warehouse; when the scheduling platform only receives the loading request and no pre-adjustment completed material handling request, a loading and handling task is generated, and the starting point in the loading and handling task is the off-line warehouse; When the scheduling platform receives the material unloading request, it generates a material unloading and handling task, and at the same time obtains the automated line corresponding to the planned processing resources of the next processing task according to the material process route, and sends the inquiry whether to accept the material; when receiving a reply that the material can be accepted, the destination in the material unloading and handling task is set to the automated line that replied; when receiving a reply that the material cannot be accepted at the current time or no reply is received within a certain period of time, the destination in the material unloading and handling task is set to the off-line warehouse; The AGV system receives the loading and unloading handling tasks, performs task handling according to the starting point and destination, and sends the AGV position and handling status to the scheduling platform in real time, and the scheduling platform updates the status and position of each material.

[0016] According to the above system, after the warehouse prepares materials and completes pre-adjustment, a person actively initiates pre-adjustment to complete the material handling request, specifically: The warehouse prepares materials according to the processing plan. The warehouse personnel call AGV to transport the materials to the on-site pre-adjustment table for the on-site fitters to bind chips to the materials to mainly identify the identities of the parts to be processed. The on-site fitters confirm the pre-adjustment of the pre-adjusted materials and initiate the material handling request.

[0017] The beneficial effects of the present invention are: combining the production and processing plan generated by the MES system, using the scheduling platform for real-time scheduling, connecting the workshop site MES, automated lines, AGV system and business data, and using scientific scheduling plans to reduce on-site waiting and repeated handling. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a method flow chart of an embodiment of the present invention.

[0019] Figure 2 It is a schematic diagram of the system structure of an embodiment of the present invention. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Glossary: MES system: Manufacturing Execution System, is a production information management system for the workshop execution level of manufacturing enterprises.

[0022] AGV: Automated Guided Vehicle, also known as automatic guided transporter or automatic guided transporter, is an industrial vehicle that loads goods automatically or manually, drives automatically along a set route or tows a cargo trolley to a designated location, and then loads and unloads goods automatically or manually.

[0023] Automated line: a production line that integrates automated production equipment and systems.

[0024] like Figure 2 As shown, the present invention provides an automated line material handling system based on mold MES production planning, including a scheduling platform, and an MES system, an automated line and an AGV system respectively connected to the scheduling platform through a network. The MES system schedules according to the resource load and generates a production and processing plan for each processing task. Specifically, after the mold order is issued, the technician compiles the parts process according to the BOM list and drawings of the mold design. Different production equipment resources will be used for processing according to different processing technologies. The MES system schedules according to the equipment resource load and gives the planned equipment (i.e. the corresponding automation line) and planned time (including planned start time and planned end time) for each processing task to form a production and processing plan.

[0025] The scheduling platform obtains the production and processing plan in real time and distributes it to the warehouse and each automated line; then, according to the production and processing plan of each automated line, the AGV system is scheduled to complete the automated material handling process.

[0026] The dispatching platform includes a data processing unit and a data transceiver unit connected to each other, wherein the data transceiver unit is connected to the MES system, the automation line and the AGV system through a network to perform data interaction; Figure 1 As shown, the data processing unit is called to perform scheduling according to the following automated line material handling scheduling method based on mold MES production plan: S1. Obtain the production and processing plan of the MES system in real time and send it to the warehouse and each automated line. The production and processing plan includes material information, process route and planned time, and the planned time includes planned start time and planned end time.

[0027] S2. When receiving the pre-adjustment material handling request and the loading request, a loading and handling task is generated and sent to the AGV. The starting point of the loading and handling task is the pre-adjustment station in the warehouse, and the destination is the loading docking station of the automated line that issued the automated line loading request.

[0028] When only a pre-adjustment material handling request is received but no loading request is received, a loading and handling task is generated and sent to the AGV, the starting point of the loading and handling task is the pre-adjustment platform in the warehouse, and the destination is the off-line warehouse. The off-line warehouse is a shelf outside the workshop.

[0029] When only a loading request is received and no material handling request is pre-adjusted, a loading and handling task is generated and sent to the AGV. The starting point of the loading and handling task is the off-line warehouse, and the destination is the loading docking station of the automated line that issued the automated line loading request.

[0030] The request for material handling after pre-adjustment is initiated by the warehouse after material preparation and pre-adjustment; the request for loading is actively initiated by the automated production line in sequence according to the time sequence in each production and processing plan.

[0031] S3. When receiving a material unloading request, a material unloading and handling task is generated and sent to the AGV. The starting point of the material unloading and handling task is the material unloading docking station of the automated line that issued the material unloading request. The material unloading request is actively initiated by each automated line according to its own material processing situation for the processed material.

[0032] At the same time, in order to save time, the materials are not sent directly to the off-line warehouse. Instead, the automated line corresponding to the planned processing resources of the next processing task is obtained according to the material's process route, and an inquiry is sent to it whether to accept the materials. When a reply is received that the materials can be accepted, the destination in the unloading and handling task is set to the automated line that replied, and the materials are sent directly from the unloading automated line to the automated line of the next processing task.

[0033] Only when a reply is received that the material cannot be received at the current time or no reply is received within a certain period of time, the destination in the unloading and handling task is set to the off-line warehouse, and the AGV delivers the material to the off-line warehouse. When the automated line of the next processing task is able to receive the material, a loading request is actively sent, and the material is subsequently loaded from the off-line warehouse according to S2.

[0034] The reply is sent by the automated line that receives the inquiry based on current circumstances.

[0035] S4. Receive the AGV position and handling status feedback from the AGV in real time, and update the status and location of each material. The material information being handled can be recorded in the handling task, and the status and location of each material can be understood based on the handling status of the AGV. For example, the parts that have completed the first process are sent to the automated line corresponding to the second process by the AGV performing the unloading and handling task; the parts that have completed the second process are sent to the off-line warehouse by the AGV performing the unloading and handling task.

[0036] Since there are many automated production lines and automated production lines of different processes are being processed at the same time, multiple handling requests may be received at the same time during the production process. The handling requests include pre-adjusted material handling requests, loading requests, and unloading requests. When multiple handling requests are received, the AGV handling tasks are generated according to the preset priority and the time of the production and processing plan, and the AGVs carry the materials in the time sequence of the handling tasks. The handling tasks include loading handling tasks and unloading handling tasks. The principle of priority is: give priority to the unloading request of the automated production line, and then consider the loading request. That is: ensure that the automated production line can be produced and processed normally, and then consider the loading request of the line.

[0037] Furthermore, in this embodiment, the priorities are as follows: unloading and handling tasks of the automated production line with the destination being the reply, unloading and handling tasks of the destination being the off-line warehouse, loading and handling tasks, and other handling tasks. The planned time of the processing tasks is considered in these four types of handling requests, and the tasks with the earlier planned start time are handled first; after the scheduling platform confirms the priorities of multiple handling requests, it will give the handling tasks to the AGV system, and then the AGV will carry out the handling in sequence according to the order of the tasks, ensuring the orderly processing and production of the automated production line on the workshop site.

[0038] The unloading and handling tasks of the automated line with the destination as the reply are given the highest priority. The purpose is to enable the materials to enter the next process from the current process as quickly as possible without having to transfer to the off-line warehouse every time, thereby improving the handling efficiency and processing efficiency. For example, a unloading and handling task with the destination as the off-line warehouse and a loading and handling task with the starting point as the off-line warehouse can be combined into a unloading and handling task of the automated line with the destination as the reply. In this way, the amount of scheduling tasks is reduced, and the amount of AGV tasks is also reduced, thereby achieving the purpose of improving the handling efficiency and the total processing efficiency.

[0039] Furthermore, in some embodiments, scheduling may be performed according to the following specific rules: First, the automated line can complete the pre-adjustment of the prerequisite materials for loading and unloading requests (after binding the chip), and then the scheduling algorithm adopts the priority and real-time scheduling algorithm rules: Priority 1: tasks that the AGV is currently carrying; Priority 2: For automated line material unloading and handling requests whose destination has been answered (the next automated line has been confirmed), a line-to-line handling task is generated and sorted in ascending order according to the planned start time of the post-processing tasks corresponding to the unloading and handling requests (i.e., the processing tasks of the corresponding materials on the next line); Priority 3: Except for the unloading and handling requests in priority 2, other unloading and handling requests of the automated line are sorted in ascending order according to the request time of the unloading and handling requests, and the tasks requested first are handled first; Priority 4: For the same material, if both the pre-adjustment completion material handling request and the material loading request exist at the same time, a loading and handling task is generated and sorted in ascending order according to the planned start time of the processing tasks corresponding to the loading and handling request; Priority 5: Automated line loading and handling requests, sorted in ascending order according to the planned start time of the processing tasks corresponding to the loading and handling requests; Priority 6 (last): AGV handling tasks (material preparation and handling requests) called manually are sorted in ascending order according to the request time point, and the tasks requested first are handled first.

[0040] The above priorities are ranked as follows: priority 1>priority 2>priority 3>priority 4>priority 5>priority 6. Based on the above scheduling algorithm rules, if there is a new handling request or a new production and processing plan is released, the order of AGV handling tasks is dynamically refreshed according to the above scheduling algorithm rules, and the AGV performs the handling in the order of the tasks.

[0041] The other handling tasks mentioned above include: manually called handling tasks. Mainly when the warehouse is preparing materials according to the processing plan, the AGV can be manually called to transport the materials to the on-site pre-adjustment station. There may also be other special situations, which can be manually called to improve the flexibility of the system.

[0042] Based on the above scheduling method, the overall handling process of this system is as follows: When the warehouse prepares materials and completes pre-adjustment, the human will initiate the pre-adjustment to complete the material handling request. Specifically, the warehouse prepares materials according to the processing plan, and the warehouse personnel call the AGV to transport the materials to the on-site pre-adjustment station. The on-site fitter binds the chip to the material to mainly identify the identity of the parts to be processed, which is convenient for subsequent automated line processing and AGV handling. The fitter confirms the AGV handling request for the pre-adjusted materials.

[0043] When the automated production line receives the current production and processing plan, it will actively initiate material loading requests in sequence according to the planned time.

[0044] The scheduling platform receives the pre-adjustment completed material handling request and the loading request, and generates a loading and handling task, in which the starting point of the loading and handling task is the pre-adjustment station of the warehouse, and the destination is the loading docking station of the automated line that issued the loading request of the automated line. When the scheduling platform only receives the pre-adjustment completed material handling request and no loading request, a loading and handling task is generated, in which the starting point of the loading and handling task is the pre-adjustment station of the warehouse, and the destination is the off-line warehouse; When the scheduling platform only receives the loading request and no pre-adjustment completed material handling request, a loading and handling task is generated, in which the starting point of the loading and handling task is the off-line warehouse, and the destination is the loading docking station of the automated line that issued the loading request of the automated line.

[0045] The automated production line will proactively initiate unloading requests for processed materials based on the processing status of its own materials.

[0046] When the scheduling platform receives the unloading request, an unloading and handling task is generated. The starting point of the unloading and handling task is the unloading docking station of the automated line that issued the unloading request. At the same time, the automated line corresponding to the planned processing resources of the next processing task is obtained according to the process route of the material, and the inquiry whether to receive the material is sent to it. If the next automated line sends a reply that it can receive the material, the destination in the unloading and handling task is set to the automated line that responded. When a reply is received that the material cannot be received at the current time or no reply is received within a certain period of time, the destination in the unloading and handling task is set to the off-line warehouse.

[0047] The dispatching platform sends the handling tasks to the AGV system, which receives the loading and unloading handling tasks and performs the task handling according to the starting point and destination, thus realizing automatic loading and unloading of the line. The AGV system sends the AGV position and handling status to the dispatching platform in real time, and the dispatching platform updates the status and location of each material.

[0048] The subsequent automated lines receive the current production plan to be processed from the MES system in turn, and actively initiate material loading requests to the scheduling platform in order of planned time.

[0049] After the scheduling platform confirms the material location, it sets the starting point of material transportation to the off-line warehouse, and the destination of parts transportation to the automated line loading and docking station; after the parts are completed, the automated line will actively initiate a material unloading request to the scheduling platform, and the scheduling platform will then confirm the destination of material transportation based on the response of the automated line of the next process.

[0050] The present invention adopts a scheduling platform to connect the workshop on-site MES, automated lines, AGV and other systems and business data, and uses scientific and intelligent scheduling plans to reduce on-site waiting and repeated transportation; through the combination of scheduling and business data, it drives automated equipment for automatic processing and timely transportation of materials, improves on-site processing efficiency and reduces the number of people in production. Due to the workshop production environment, it can also effectively improve the safety of workshop operations.

[0051] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
