Description

Technical Field

[0001] This application relates to the field of logistics and distribution technology in production workshops, specifically to a pallet distribution method, apparatus, system, storage medium, and processor for material sorting. Background Technology

[0002] In manufacturing, especially in the automotive and construction machinery industries, to ensure material supply to production lines, materials requiring mixing are sorted and palletized before delivery. However, the same material is often used in multiple production lines, and a single demand often requires hundreds or thousands of materials. Current technology typically involves manually arranging the picking sequence. This manual arrangement is not only inefficient and increases labor costs, but also leads to duplicate deliveries of the same pallet if the same material is needed at multiple sorting stations. Furthermore, when multiple sorting stations require the same material, it's impossible to dynamically adjust the pallet delivery sequence based on the picking situation at each station to meet timely picking demands. Summary of the Invention

[0003] The purpose of this application is to provide a pallet delivery method for material sorting, in order to solve the technical defects in the prior art that cannot dynamically adjust the pallet delivery order based on the picking situation of each sorting station.

[0008] Determine the types of materials that can be picked from each pallet;

[0009] For each sorting station, the pallet with the largest quantity of material type to be picked in the target order to be sorted at the sorting station will be prioritized for picking.

[0010] For each pallet, the picking order of each material is sorted according to the quantity of each material in the target order to be sorted at each sorting station, with the material with the larger quantity being picked first.

[0011] For each pallet, control the picking and delivery of pallets from the sorting station according to the priority assigned to each sorting station and the picking order of each material in each sorting station.

[0014] In an embodiment of this application, the pallet delivery method further includes: for each sorting station, if any one of the first pallets and the second pallet among the multiple pallets have the same quantity of material type to be picked in the target order to be sorted at the sorting station, determining the first material quantity of the first pallet for the corresponding material to be picked, and the second material quantity of the second pallet for the corresponding material to be picked; and prioritizing the allocation of the pallet with the largest quantity between the first material quantity and the second material quantity to the sorting station for picking.

[0016] In embodiments of this application, the production workshop further includes pallet delivery equipment, and the pallet delivery method further includes: generating a pallet delivery order for the pending task based on the priority of each pallet being assigned to each sorting station and the delivery order of each material in each sorting station; and controlling each pallet to be picked and delivered to each sorting station by the pallet delivery equipment based on the pallet delivery order.

[0037] Figure 1 This illustration schematically depicts a process flow diagram of a pallet delivery method for material sorting according to an embodiment of this application. For example... Figure 1 As shown in the figure, this application provides a pallet delivery method for material sorting, which may include the following steps.

[0038] Step 101: Determine the wave number corresponding to each order to be sorted in each sorting station.

[0039] In this embodiment, it should be noted that sorting is the operation of categorizing and stacking materials according to their type and the order of their entry and exit from the warehouse. A sorting station can refer to an area used for material sorting. Sorting personnel work at the sorting station to sort the materials to be sorted into the corresponding pallets. A pallet can refer to a container used to hold materials. Wave numbers are generally used in the warehouse outbound process. According to the wave rules set by the system, orders with the same common characteristics are grouped together for picking and shipping to reduce repetitive operations. For example, wave number 1 can be set as orders that need to be shipped before 1 pm, and wave number 2 can be set as orders that need to be shipped before 2 pm. In this technical solution, each sorting station can include multiple orders to be sorted, each order can include multiple materials, and each order has a unique wave number. Therefore, before sorting, it is necessary to determine the wave number corresponding to each order to be sorted in each sorting station.

[0040] Step 102: For each sorting station, identify the orders to be sorted that have the same wave number as the wave number of the task to be processed as the target orders to be sorted.

[0041] In this embodiment, after determining the wave number corresponding to each order to be sorted in each sorting station, for each sorting station, the orders to be sorted whose wave number is the same as the wave number of the task to be processed are identified as target orders to be sorted. For example, taking a production workshop including sorting station 1, sorting station 2, and sorting station 3, and the wave number of the task to be processed is ①, the wave numbers of orders to be sorted A and B in sorting station 1, orders to be sorted F, G, H, and L in sorting station 2, and orders to be sorted X, Y, and Z in sorting station 3 are all the same as the wave number of the task to be processed, all being ①. Therefore, orders to be sorted A, B, F, G, H, L, X, Y, and Z can be identified as target orders to be sorted in the corresponding sorting stations.

[0042] Step 103: For each target order to be sorted, determine the materials required for the target order to be sorted and the quantity of each material.

[0043] In this embodiment of the application, each order to be sorted may include multiple materials. Therefore, after determining the target order to be sorted in each sorting station, for each target order to be sorted, it is necessary to determine the materials required for that target order to be sorted and the quantity of each material. Figure 2 The diagram shown illustrates material information under a sorting wave number. Figure 2As shown, when the wave number of the task to be processed is ①, taking target orders A and B in sorting station 1 as examples, target order A can include material 1 with a quantity of 1, material 2 with a quantity of 2, and material 3 with a quantity of 2. Target order B can include material 1 with a quantity of 1, material 3 with a quantity of 1, material 4 with a quantity of 2, and material 5 with a quantity of 1. Taking target orders F, G, H, and L in sorting station 2 as examples, target order F can include material 1 with a quantity of 2, target order G can include material 2 with a quantity of 2, material 3 with a quantity of 2, target order H can include material 4 with a quantity of 2, and target order L can include material 3 with a quantity of 1 and material 5 with a quantity of 3. Taking target orders X, Y, and Z in sorting station 3 as examples, target order X may include 2 units of material 1 and 3 units of material 3; target order Y may include 2 units of material 2 and 1 unit of material 4; and target order Z may include 1 unit of material 4 and 3 units of material 5. It should be noted that materials 1, 2, and 3 do not represent the same type of material; they are used to indicate the first, second, and third types of materials, respectively. Furthermore, material 1 in different sorting stations may be the same type of material or different types of materials. The numbers here are only used to indicate that multiple materials are included.

[0044] Step 104: Determine the types of materials that can be picked from each pallet.

[0045] In this embodiment, it should be noted that the types of materials that can be picked from each pallet in this technical solution are different. For example, taking a production workshop including pallet 1 and pallet 2 as an example, pallet 1 can be used to sort materials 1 and 2, and pallet 2 can be used to sort materials 3 and 4. Different pallets are not sorted for the same type of material. Therefore, before sorting the materials included in the target order to be sorted in each sorting station, it is necessary to first determine the types of materials that can be picked from each pallet, so as to match the corresponding pallet to the materials in each sorting station.

[0046] In this embodiment, as Figure 3The diagram illustrates a material distribution pallet system at a sorting station. When the wave number of the task to be processed is ①, materials 1 and 2 in sorting station 1 are assigned to pallet 1, materials 3, 4, and 5 are assigned to pallet 3. Similarly, materials 1 and 2 in sorting station 2 are assigned to pallet 1, materials 3 and 4 to pallet 3, and material 5 to pallet 4. In sorting station 3, materials 1 are assigned to pallet 1, materials 2 to pallet 2, materials 3 to pallet 3, and materials 4 and 5 to pallet 5. It should be noted that pallets with the same pallet code used by different sorting stations are considered the same pallet. For example, the same pallet 1 is used in sorting stations 1, 2, and all of them.

[0047] Step 105: For each sorting station, prioritize the allocation of the pallet with the largest quantity of material type to be picked from the target order to the sorting station for picking.

[0048] In this embodiment of the application, after assigning corresponding pallets to each type of material included in each target order to be sorted in each sorting station, for each sorting station, the pallet with the largest quantity of material type to be picked in the target order to be sorted at that sorting station is preferentially assigned to the sorting station for picking. For example... Figure 3 As shown, taking sorting station 1 as an example, sorting station 1 is allocated with pallet 1 and pallet 3. Pallet 1 is allocated with two types of materials, material 1 and material 2, while pallet 3 is allocated with three types of materials, material 3, material 4 and material 5. Obviously, the number of material types allocated to pallet 3 (3) is greater than the number of material types allocated to pallet 2 (2). Since pallet 3 has the largest number of material types, it is prioritized to allocate pallet 3 to sorting station 1 for picking. The priority order is pallet 3, pallet 1.

[0049] In this embodiment, as shown in Table 1, the arrangement priority of each pallet in each sorting station is provided, including:

[0050] Table 1 Pallet Delivery and Picking Sequence

[0051]

[0052] As shown in Table 1, taking sorting station 1 as an example, pallet 3 has 3 types of picking materials and pallet 1 has 2 types of picking materials. Therefore, the priority of pallet arrangement is pallet 3, pallet 1.

[0053] In this embodiment of the application, the pallet delivery method further includes: for each sorting station, if any one of the first pallets and the second pallet among the multiple pallets have the same quantity of material type to be picked in the target order to be sorted at the sorting station, determining the first material quantity of the corresponding material to be picked for the first pallet and the second material quantity of the corresponding material to be picked for the second pallet; and prioritizing the allocation of the pallet with the largest quantity between the first material quantity and the second material quantity to the sorting station for picking.

[0054] In this embodiment, for each sorting station, if any first pallet and second pallet among multiple pallets have the same quantity of the type of material to be picked at that sorting station, the priority of the pallets needs to be further determined based on the first and second material quantities of the materials to be picked for the first and second pallets. Specifically, as shown in Table 1, taking sorting station 2 as an example, pallet 3 and pallet 1 are each assigned two types of materials. Therefore, it is necessary to further determine the quantity of materials to be picked for pallets 3 and 1. As shown in Table 1, the quantity of materials to be picked for pallet 3 is 5, and the quantity of materials to be picked for pallet 1 is 4. Obviously, the quantity of materials to be picked for pallet 3 is higher than that for pallet 1. Therefore, the priority of pallet arrangement is pallet 3, then pallet 1.

[0055] In the embodiments of this application, the pallet delivery method further includes: for each sorting station, when the quantity of the first material and the quantity of the second material are the same, obtaining the first pallet number corresponding to the first pallet and the second pallet number corresponding to the second pallet respectively; and prioritizing the allocation of pallets whose numbers between the first pallet number and the second pallet number are in the priority order of the preset number sequence to the sorting station for picking.

[0056] In this embodiment, for each sorting station, if any first pallet and second pallet not only have the same type of material assigned to them at that sorting station, but also the same quantity of material, it is necessary to further determine the priority of the first pallet and the second pallet. Specifically, this can be determined based on the pallet numbers of the first and second pallets. Therefore, the first pallet number corresponding to the first pallet and the second pallet number corresponding to the second pallet are obtained respectively, and the pallets whose numbers fall within the priority order of the preset numbering sequence are preferentially assigned to the sorting station for picking. The preset numbering sequence can be set according to requirements, and a numbering sequence can include, but is not limited to, a single number, a single letter, multiple numbers, or multiple letters. In this technical solution, the preset numbering sequence can be set to consist of a single number, that is, arranged in the order of natural numbers such as 1, 2, 3, 4, etc. For example, if the pallet numbers corresponding to the first and second pallets are 1 and 3 respectively, then the priority of the pallets is the first pallet, and the priority is the second pallet.

[0057] Step 106: For each pallet, sort the picking order of each material in the target order to be sorted at each sorting station according to the quantity of each material. The material with a larger quantity is picked first.

[0058] In this embodiment, after determining the picking priority of each pallet at each sorting station, the picking order for each pallet is sorted according to the quantity of each type of material in the target order to be sorted at each sorting station. Materials with larger quantities are picked first. That is, for each pallet at each sorting station, if the pallet is assigned multiple types of materials, the picking order for these multiple types of materials needs to be further determined. Specifically, the order can be based on the quantity of each type of material, prioritizing the picking of materials with larger quantities.

[0059] In this embodiment, as shown in Table 2, a pallet material picking sequence is provided, including:

[0060] Table 2 Pallet Material Picking Sequence

[0061]

[0062]

[0063] As shown in Table 2, taking sorting station 1 as an example, after determining the priority order of pallet 3 and pallet 1 as pallet 3, pallet 1, pallet 3 needs to deliver materials 3, 4, and 5. According to... Figure 3 It can be seen that the quantity of material 3 is 3, the quantity of material 4 is 2, and the quantity of material 5 is 1. The quantities of materials are arranged in order from most to least as material 3, material 4, and material 5. Therefore, for pallet 3, the picking order of materials is material 3, material 4, and material 5.

[0064] In the application embodiment, the pallet delivery method further includes: for any pallet, if the pallet has the same priority in any two sorting stations, obtaining the quantity of material types to be picked in the target order to be sorted in each sorting station, and prioritizing the allocation of the pallet to the sorting station with the largest quantity of material types to be picked; for the other sorting station, prioritizing the allocation of the first pallet with the priority after the pallet to the sorting station for picking.

[0065] In this embodiment, as shown in Table 2, after arranging the pallet delivery order and picking order for sorting stations under the same wave number, it will be found that the same pallet is needed in multiple sorting stations, that is, the priority is the same in each sorting station. Taking sorting station 1 and sorting station 2 as examples, the highest priority pallet in both sorting station 1 and sorting station 2 is pallet 3. At this time, there are two situations:

[0066] a. The delivery order of the same pallet is different in each sorting station, but the sorting efficiency of each sorting station is different during the picking process, which may eventually lead to multiple sorting stations needing the same pallet at the same time;

[0067] b. The order of pallet delivery is the same, but the order of demand may change depending on the picking progress.

[0068] Therefore, it is necessary to intelligently arrange the picking order of sorting stations based on the dynamic picking situation of the sorting stations, and dynamically adjust the delivery order of each pallet. For any pallet, if the pallet has the same priority in any two sorting stations, the quantity of the material types to be picked in the target order to be sorted in each sorting station is obtained, and the pallet is preferentially assigned to the sorting station with the largest quantity of the material types to be picked. For the other sorting station, the first pallet with the next priority is preferentially assigned to the sorting station for picking. Specifically, the adjustment is based on the types and quantities of the materials to be picked in the pallet, prioritizing the sorting station with more types of materials to be picked, while the other sorting station skips the pallet and picks the next pallet. After the conflicting pallet becomes available, the next pallet is inserted for picking. The adjustment of the pallet order is also accompanied by the update of the AGV delivery task. For example, as shown in Table 2, both sorting station 1 and sorting station 2 require pallet 3 in the order of 1. However, sorting station 1 needs 3 types of materials from pallet 3, while pallet 2 needs 2 types of materials from pallet 3. Therefore, pallet 3 is prioritized for sorting station 1, while sorting station 2 temporarily skips pallet 3 and sorts the next pallet 1 first. This process continues, dynamically adjusting the order of pallets and materials to ensure that each sorting station has goods to pick and is on the optimal picking path.

[0069] In the application embodiment, the pallet delivery method further includes: when the quantity of material type to be picked in the target order to be picked in each sorting station is the same, obtaining the quantity of material for the corresponding material to be picked in each sorting station, and prioritizing the allocation of the pallet to the sorting station with the largest quantity of material for picking.

[0070] In this embodiment, if the quantity of material types to be picked in the target order to be picked is the same for each pallet at each sorting station, the pallet allocation order is further determined based on the quantity of material to be picked for each pallet at each sorting station. Specifically, the quantity of material for the corresponding material to be picked for each pallet at each sorting station is obtained, and the pallets are preferentially allocated to the sorting station with the largest quantity of material for picking.

[0071] Step 107: For each pallet, control the pallet to be picked and delivered from the sorting station according to the priority assigned to each sorting station and the picking order of each material in each sorting station.

[0072] In this embodiment of the application, for each pallet, after determining the priority of each pallet in each sorting station and the picking order of each pallet for each material in each sorting station, the pallet is controlled to be picked and delivered from the sorting station according to the priority assigned to each sorting station and the picking order of each material in each sorting station.

[0073] In this embodiment of the application, the production workshop also includes pallet delivery equipment, and the pallet delivery method further includes: generating a pallet delivery order for the task to be processed based on the priority of each pallet being assigned to each sorting station and the delivery order of each material in each sorting station; and controlling each pallet to be picked and delivered to each sorting station by the pallet delivery equipment based on the pallet delivery order.

[0074] In this embodiment, it should be noted that the pallet delivery equipment can refer to an AGV, which is an automated guided vehicle, also known as an automated guided transport vehicle or automated guided transport vehicle. AGVs can be used to deliver the pallets required at each sorting station to that sorting station. After determining the priority of each pallet at each sorting station and the picking order of each pallet for each material at each sorting station, a pallet delivery order for the pending task is generated based on the priority of each pallet assigned to each sorting station and the delivery order of the pallets for each material at each sorting station. The pallet delivery equipment can then control each pallet to be picked and delivered to each sorting station based on this pallet delivery order.

[0075] The above technical solution provides a pallet delivery method for material sorting. By comprehensively considering the picking situation at each sorting station, it determines the priority of each pallet at each sorting station and the picking order for each type of material based on the quantity, type, and quantity of materials to be picked at each sorting station. This enables dynamic adjustment of the pallet order based on the picking situation at each sorting station. This not only saves labor costs but also reduces the number of pallet transfers, ensures the timeliness of picking needs, and supports high-efficiency production.

[0076] This technical solution comprehensively considers the picking situation at each sorting station. By analyzing the materials to be picked and their quantity at each sorting station, as well as the number of types of materials to be picked on each pallet, the system dynamically sorts and automatically generates a picking task list and a pallet delivery list. A picking order is assigned to the sorters, and a delivery task order is assigned to the AGVs. The AGVs simply need to follow this order for delivery.

[0077] This application provides a pallet delivery device for material sorting, including:

[0078] The memory is configured to store instructions; and

[0079] The processor is configured to retrieve the instructions from the memory and, when executing the instructions, to implement the pallet delivery method for material sorting described above.

[0083] In one embodiment, such as Figure 4 As shown, production workshop 420 also includes:

[0084] Pallet delivery equipment 423 is used to control the allocation of each pallet to each sorting station for picking and delivery.

[0085] This application provides a storage medium storing a program that, when executed by a processor, implements the pallet delivery method for material sorting described above.

[0086] In one embodiment, a computer device is provided, which may be a server, and its internal structure diagram may be as follows: Figure 5As shown.

The internal memory A03 provides an environment for the operation of the operating system B01 and the computer program B02 stored in the non-volatile storage medium A04. The database stores data on pallet delivery methods for material sorting. The network interface A02 communicates with external terminals via a network connection. The computer program B02 is executed by the processor A01 to implement a pallet delivery method for material sorting.
