Description

Technical Field

[0001] The present invention relates to a material management system, and in particular to a method and system for replacing an intelligent return function after transporting. Background Art

[0002] Generally, after the materials are processed by the process equipment, they will be temporarily stored in the stereoscopic warehouse closest to the next process. However, if there is no available space in the stereoscopic warehouse, they will be placed in the alternative stereoscopic warehouse. When the material is called next time, it will be called from the alternative stereoscopic warehouse, which will increase the cost of distance and time. Therefore, during the process of the material waiting in the stereoscopic warehouse, if the space in the original stereoscopic warehouse is vacant, the present invention will automatically dispatch the material from the alternative stereoscopic warehouse to the original stereoscopic warehouse. Summary of the invention

[0003] The present invention aims to overcome the above-mentioned defects. After the material is replaced to the replacement warehouse, when the system determines that the state of the original warehouse is restored or the space that can be placed in the material is vacated, the system automatically generates a handling task to move the material from the replacement warehouse to the original warehouse. In this way, when the next station process equipment needs to load materials, it can ensure that the materials are called from the warehouse closest to the process equipment. In addition, the present invention also solves the problem of frequent switching of warehouses. Through the overall calculation of the travel time, the space of the warehouse is predicted.

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 , a specific itinerary diagram during the operation of the system and method provided in this embodiment.

[0041] Figure 2 , a flowchart of the system and method provided in this embodiment during operation. DETAILED DESCRIPTION

[0042] The present invention is capable of various modifications and various embodiments, and therefore specific embodiments are illustrated and described in the accompanying drawings. However, this is not intended to limit the present invention to specific implementations, but should be understood to include all modifications, equivalents, and even substitutes that fall within the concept and technical scope of the present invention.

[0043] This embodiment provides a system capable of intelligent return function, including a transport module and an inventory management module;

[0044] Wherein, the transport module includes a transport instruction submodule and a transport submodule;

[0045] The transport submodule includes a transport device, which can transport materials to a destination according to the material transport instructions of the transport instruction submodule;

[0046] Inventory management module, which counts the inventory quantity, location information and entry and exit time nodes of the current warehouse (the entry and exit time nodes are in the background, and real-time updated data can be obtained based on the entry and exit of each material);

[0047] The above-mentioned handling instruction submodule creates material handling instructions based on the target warehouse inventory, location information, and entry and exit time nodes of each material, as well as the inventory and location information of other warehouses. The specific methods for creating handling and handling instructions are as follows:

[0048] S1. When the material is processed, the warehouse closest to the next process station is obtained according to its location;

[0049] S2. Determine whether the nearest warehouse has storage space.

[0050] In this process, one solution is to directly determine whether there is storage space based on the inventory status in the inventory management module. In another solution, in order to improve the efficiency of transfer, it is also possible to further determine whether the target warehouse can vacate storage space within a specified time, thereby enabling the material to be directly transported to the final warehouse without the need to enter and exit the alternative warehouse, which greatly saves the operation process and time and releases more transportation capacity of transportation equipment.

[0051] The specified time here can be the time required for the current material to be transported to the nearest warehouse by the handling equipment (for example, it takes 3 minutes for the current material to be transported to the nearest warehouse. According to the sorting table of the entry and exit time nodes of each material in the inventory management module, it can be found that there is a material that is shipped out in the next 3 minutes, which does not affect the entry of this material, and it is considered to be within the specified time), or it can be the time preset by the system (for example, if the warehouse cannot be vacated within 5 minutes, the material will be transported to an alternative warehouse);

[0052] When the answer is "yes", instruct the handling equipment to transport the materials to the nearest warehouse;

[0053] When the result is "No", proceed to S3;

[0054] S3. Select an alternative warehouse with storage space closest to the nearest warehouse and instruct the handling equipment to transport the materials into it;

[0055] The above process of selecting the alternative warehouse with storage space closest to the closest warehouse includes:

[0056] S3-1. Search for the alternative warehouse closest to the nearest warehouse and determine whether it has storage space;

[0057] When the answer is "yes", instruct the handling equipment to transport the materials to the warehouse;

[0058] When the answer is "No", proceed to S3-2;

[0059] S3-2. Search for an alternative warehouse that is Nth closest to the closest warehouse and determine whether it has storage space, where N is an integer of 2.3.4....;

[0060] When the answer is "yes", instruct the handling equipment to transport the materials to the warehouse;

[0061] When the result is "No", S3-2 is repeated until a warehouse with storage space is found.

[0062] In the above process, it is also determined in real time whether the alternative warehouses can have inventory vacancy within the specified time, so as to avoid the materials being transported to more distant warehouses;

[0063] When none of the above situations occur, the materials have to be transported to a warehouse a little further away.

[0064] S4. Real-time monitoring of the nearest warehouse to see if there is any new storage space available.

[0065] When the answer is "yes", the handling equipment is instructed to transport the material to the nearest warehouse, and the instruction continues to run until the material is transported out.

[0066] The status of the above warehouse can be expressed as follows in the background:

[0067] No. state Available / Unavailable 1 Online Available 2 Offline Unavailable 3 Faulty storage entrance Unavailable 4 The warehouse entrance is normal Available 5 Device manual mode Unavailable 6 Device automatic mode Available 7 Liquidation Unavailable 8 Liquidation Available

[0068] like Figure 1 and 2 As shown, it includes the following steps:

[0069] Step 1. MES unloading request MES sends unloading command to MCS

[0070] Step 2. MCS unloading materials MCS sends unloading orders based on MES to OMS

[0071] Step 3. OMS response to the material unloading request result After receiving the material unloading request from MCS, OMS returns a success or failure message to MCS

[0072] Step 4. MCS unloading request MCS receives the unloading request from MES and returns a success or failure message to MES

[0073] Step 5. The trolley receives the material. The OMS designates a trolley to pick up the material.

[0074] MCS determines that the STK status is abnormal or the warehouse is full, and moves the material to the alternative STK

[0075] Step 6. Change Destination Request MCS sends a change destination request to OMS

[0076] Step 7. Accept the change destination request. OMS receives the command and returns it to MCS.

[0077] Step 8. Cart unloading OMS sends the car to the replacement STK

[0078] After the FOUP is put into storage, the MCS determines that the STK status has been restored or the warehouse is free to place materials, and generates a transport command to move the material to the original STK

[0079] Step 9. Transport Request MCS sends a transport request to OMS

[0080] Step 10. Transfer request receiving OMS receiving task

[0081] Step 11. The trolley receives the material from the starting point.

[0082] Step 12. The trolley puts the material to the destination STK

[0083] Step 13. Material loading request MES sends a material loading request to MCS

[0084] Step 14. Material upload request MCS sends a material upload request to OMS based on the command of MES

[0085] Step 15. Receiving the material upload request OMS receives the material upload request and responds

[0086] Step 16. The material feeding request is successfully replied. MCS reports the OMS reply result to MES

[0087] Step 17. The trolley receives the material from the starting point.

[0088] Step 18. The trolley unloads the material. The trolley unloads the material to the next process equipment.

[0089] Although the above description is centered on the embodiment, it is only an example and does not limit the present invention.
