Description

Technical Field

[0001] This application relates to the field of logistics technology, and in particular to a material handling method and equipment. Background Technology

[0002] In smart factory workshops, manufacturing, and logistics warehousing scenarios, automated material management is particularly important. However, different manufacturers have different material management equipment, and there is no unified design scheme for related data models.

[0003] When multiple nested storage containers exist for storing materials, determining whether a container holds material requires relying on the specific carrier that holds the material. For example, suppose container A can hold material B, but material B needs to be placed in a special carrier A1. In this case, determining whether container A holds material B requires considering the following two nesting relationships: Based on whether A1 is placed in carrier A, and considering whether material B exists in A1, Thus, the process of determining whether there is material B on vehicle A based on these two judgment logics is too redundant. Such a material management method is complex and inefficient, and it is also not conducive to the design of system business functions. Summary of the Invention

If they are consistent, the second target location is replaced with the first target location, and the reverse logistics strategy is changed to a delivery strategy.

[0012] Optionally, in the case where the vehicles are stackable and multiple vehicles are stacked in one place, the multiple vehicles correspond to one storage location.

[0013] Optionally, based on material distribution needs and / or reverse logistics needs, determine the material attributes of the materials to be handled, including: Based on the material attributes of the material to be transported, match the transport vehicle that is not bound to other storage locations or materials; A virtual vehicle number is generated for the vehicle to be transported, and the virtual vehicle number is bound to the material to be transported; The method further includes: after transporting the vehicle to be transported to the loading target location, unbinding the virtual vehicle number and deleting the virtual vehicle number.

Detailed Implementation

[0017] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application. Any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present application.

[0018] This application provides an SCM model applied to material management equipment, wherein the SCM model represents the spatial relationship between slots, carriers, and materials.

[0019] See Figure 1 As shown, based on the above SCM model, this application provides a material handling method, including: S101: Determine the materials to be moved based on handling requirements; S102: Based on the materials to be transported and the SCM model, match the transport vehicles and / or storage locations, wherein the SCM model is a model constructed based on the spatial relationship between materials, vehicles, and corresponding storage locations. S103: Move the materials to be transported to the target location.

[0020] For example, the target location could be a workstation, which represents the smallest unit of work for completing a process operation.

[0021] See Figure 2 As shown in the embodiments of this application, the spatial relationship between storage locations, vehicles, and materials can be represented by (x, y, z). Here, a storage location represents an atomic position unit in the material management equipment. An atomic position unit can be a coordinate point on a map, and its classification can include two types: point locations and warehouse locations. A point location is a position in a two-dimensional plane (physical coordinate point), while a warehouse location is a position in three-dimensional space (physical coordinate point), which can represent a position on a fixed shelf in a warehouse. In the SCM model, each storage location can correspond to a unique storage location number, with a maximum length of 64 bits. This unique storage location number allows a specific physical location to be determined on the map.

[0022] Carriers are used to store materials and are the direct objects handled by autonomous mobile robots. For example, carrier types include shelves and other storage devices. These other storage devices may include pallets, bins, etc. Carriers of the same type may contain different specifications, and the specification identifier for each carrier may include its size and shape. Figure 2 The vehicle shown here is a cuboid shape, but this is just an example. The vehicle can also be a pallet, a bin, etc.

[0023] If the type of the vehicle is a shelf, then the storage location corresponding to the vehicle is a storage location; If the carrier type is another storage device, the storage location corresponding to the carrier is a point location and / or a warehouse location. For example, if the carrier type is a bin or pallet, its storage location can be either a point location or a warehouse location. Furthermore, if the carriers are stackable, multiple carriers can be stacked in one place. For example, multiple pallets can be stacked and bound to one storage location, forming a relationship where multiple carriers correspond to one storage location. The stackable carrier types can be expanded according to actual business scenarios, reducing the levels of binding relationships, avoiding complex scheduling paths, and thus faster meeting the real-time scheduling needs of material management equipment.

[0024] In this embodiment, "material" refers to the object processed on the production line, and may include finished products, semi-finished products, and waste. The production cycle time of the material may include one or more of the following: producing finished products, producing semi-finished products, waste materials, and remaining materials. Material attributes may include material category, material unique identifier, and real-time attribute values, where material category can represent the classification of the material. Materials may have initialization attributes and default attribute values.

[0025] For example, after a material undergoes different processing techniques, its real-time temperature is 100 degrees Celsius. After two hours of cooling, the real-time temperature of the material becomes 20 degrees Celsius.

[0026] In this case, the material attributes and material data of the materials to be transported can be determined based on material distribution needs and / or reverse logistics needs.

[0027] The size, shape, and production cycle of materials are determined based on material production requirements; the type of vehicle corresponding to material distribution requirements and / or reverse logistics requirements is determined based on the size, shape, and production cycle of materials. Material distribution requirements may include loading, unloading, and replenishment, while reverse logistics requirements may include logistics requirements such as recycling waste materials, surplus materials, and idle vehicles generated during the production process.

[0028] For example, when the generation cycle is in the state of producing semi-finished products, and the temperature attribute of the material is 100 degrees Celsius, the specification of the matched carrier needs to include metal. Combining the shape of the material to be transported in the state of producing semi-finished products, a metal pallet is matched as the carrier. When the cycle time is set to the finished product production state, the material's temperature attribute is 20 degrees Celsius. Based on the batch delivery requirements, a shelf is selected as the carrier. This allows the autonomous mobile robot to move all the finished products on the shelf together to the target location.

[0029] See Figure 3 As shown, a material can only be placed on one vehicle, but a vehicle can hold multiple materials, and different types of materials can be placed in the same vehicle.

[0030] After determining the spatial relationship between the storage location, the vehicle, and the materials, the materials to be transported can be bound based on the SCM model. Based on the SCM model and the production cycle time, a delivery strategy corresponding to the material delivery demand is determined. The delivery strategy includes at least one of the following: material code to be transported, first entry / exit sequence, first delivery starting point, and first target location. Based on the SCM model, the production cycle time, and vehicle idle status, a reverse logistics strategy is determined. The reverse logistics strategy includes at least one of the following: the coding of the target to be recycled, the second entry and exit sequence, the second delivery starting point, and the second target location.

[0031] This feeding strategy can be determined, but is not limited to, through the following methods: Based on at least one of the material's size, shape, production cycle time, and carrier specifications, the corresponding carrier type is determined. Machine attributes are matched based on the material attributes. Based on at least one of the following indicators—storage space utilization, material consumption, and replenishment turnover—and in conjunction with the SCM model, a material pull route is determined to move the material to be transported to the machine station corresponding to the specified machine attribute. During the generation of the material pull route, spatial layout optimization between workstations and materials can be implemented based on production plans and production needs to ensure that workstations and materials are grouped accordingly and that the distance between each group of workstations and materials is minimized.

[0032] The aforementioned machine attributes may include, but are not limited to, cleaning machines, heating machines, and deposition machines, etc., and are not limited here. For example, the carrier type for a heating machine can be a metal tray. The carrier type for a cleaning machine can be a plastic frame, stainless steel tray, etc.

[0033] For example, different workstations can be configured with different specifications of carriers based on factors such as processing technology and space constraints. By combining the constraints of material attributes, processing technology, and carrier specifications, a set of full-condition storage locations that meet the workstation-carrier-material matching relationship can be matched. Then, by combining the material loading strategy in the distribution strategy, the storage locations in the set of full-condition storage locations can be sorted.

[0034] Optionally, the material loading strategy may include, but is not limited to, the following sorting methods based on spatial relationships: 1. Sort the items in order of distance from the workstation, from closest to furthest. 2. Sort them in order of distance from the workstation, from farthest to nearest; 3. Sort the materials according to the order in which they were taken out; 4. Sort according to the serpentine position; 5. Sort according to the order of first-in-first-out or first-in-last-out.

[0035] First-in-first-out (FIFO) order can be used to describe materials with limited shelf life, while last-in-first-out (LIFO) order can be used to describe dead ends in spatial layout.

[0036] Based on the material loading strategy, material outbound is carried out, with the first delivery starting point being the first storage location and the first target location being the first machine station, thus generating a material pull route.

[0037] See Figure 4 As shown, different feeding strategies can be set for a single buffer in the line-side buffer area. The feeding strategy can include the type of feeding strategy, the retrieval start point, the retrieval order, etc. Types of material loading strategies: by location, by distance; The starting points for extraction include: top left, bottom left, top right, and bottom right. The extraction order includes: row by row from left to right, serpentine from left to right, column by column from top to bottom, serpentine from top to bottom, etc.

[0038] During production cycles involving finished products, semi-finished products, waste materials, and surplus materials, the following reverse logistics configurations can be implemented for abnormal materials and / or idle vehicles: After determining the vehicle type and reverse logistics strategy corresponding to the reverse logistics demand, the method further includes: Based on the aforementioned reverse logistics strategy, abnormal materials and / or idle vehicles in the production process are recovered; The statistics on the recovery of the abnormal materials are fed back to the material management equipment so that the material management equipment can analyze the material abnormalities; The status of the retrieval of the idle vehicles is fed back to the material management equipment to update the storage location of the materials.

[0039] Abnormal materials include, but are not limited to, waste materials and materials with incorrect properties. For example, materials at 100 degrees Celsius might be mistakenly placed on a shelf where materials intended for 20 degrees Celsius should be. Or, metal materials might be placed at a workstation intended for plastic materials. Feedback on the recovery of these abnormal materials and the recovery of idle containers to the material management system allows for more timely updates to material storage locations.

[0040] Optionally, if the code of the material to be transported in the delivery strategy is consistent with the code of the target to be recycled in the reverse logistics strategy, the reverse logistics strategy can be interrupted, the second target location can be replaced with the first target location, and the reverse logistics strategy can be changed to a delivery strategy.

[0041] For example, see Figure 5As shown, in process 1, machine equipment A port (station A) unloads material into line-side buffer area C. In process 2, machine equipment B port (station B) calls material from line-side buffer area C (calls for loading). At this time, the code of the material to be recycled unloaded in process 1 is consistent with the code of the material to be transported loaded in process 2. Therefore, process 1 can be interrupted directly, the first target position in process 2 can be used to cover the second target position in process 1, and the strategy type of process 1 can be changed to delivery strategy.

[0042] The process can be as follows: 1) When station A generates a feeding signal, the material management equipment selects an empty storage location in the line-side buffer area C that meets the preset feeding strategy according to the preset feeding strategy. The carrier 1 carrying the material moves the material from station A to the empty storage location in the line-side buffer area C. In this way, the material can be stored in the empty storage location in the line-side buffer area C through the SCM model.

[0043] To meet the material unloading needs, the remaining materials will be put into storage. The material pulling route can be set as follows: the first delivery starting point is the second machine station (station A), and the first target location is the second storage location (an empty storage location in the line-side buffer area C).

[0044] 2) When workstation B generates a feeding signal, the material management equipment selects a full-condition storage location (the storage location is bound to the carrier and the material to be fed) that meets the feeding signal matching conditions from the line-side buffer area C. In this way, the process of taking out the material to be fed can be realized based on the SCM model. If the priority interruption of the in-transit process configuration is enabled at this time, the code of the material to be transported in the delivery strategy and the code of the target to be recycled in the reverse logistics strategy are checked by synchronously querying the full-condition vehicle in transit (e.g., Carrier1). If they are consistent, process 1 is interrupted, the first target position is replaced with the second target position, process 1 is changed to process 3, process 2 is deleted, and the idle storage space originally occupied in process 1 is released.

[0045] For example, during the above comparison process, it is also possible to compare whether the quantity of materials on Carrier1 meets the material loading requirements of station B. If not, other unloading processes can be interrupted or a new material loading process can be added.

[0046] For example, subtract the amount of material in the interrupted unloading process from the material loading demand of station B to obtain the remaining material demand. Based on the remaining material demand, find the full-condition carrier from the line-side buffer area and generate a new material loading process.

[0047] Prioritizing interruptions in-transit processes can effectively utilize the reclaimable targets in reverse logistics strategies, reduce repeated round trips for vehicles, effectively shorten handling time, and improve material handling efficiency. The aforementioned line-side buffer area C can be one or more independent material buffer areas.

[0048] See Figure 6 As shown, Figure 6 This is a schematic diagram of the SCM binding operation page in the embodiments of this application. The binding of the SCM model can realize the binding of materials, vehicles and storage locations with one click, or it can bind materials and vehicles separately (CM relationship), or bind vehicles and storage locations separately (SC relationship).

[0049] For example, for materials for which a material distribution plan or reverse logistics plan has not yet been initiated, only the relationship between the material and the vehicle can be bound. For idle vehicles that have been recycled, the relationship between the vehicle and the storage location can be bound separately.

[0050] In this embodiment, the material to be transported and the transport vehicle are matched based on material attributes. The material to be transported and / or the transport vehicle are bound to the storage location based on the SCM model between the two and the storage location, thereby moving the transport vehicle to the target location. There is no need to find a special vehicle to carry the material, avoiding machine recognition errors or transport errors caused by multi-layer nested relationships. Moreover, since the SCM model only has three layers, it is simpler and the logic is clearer compared to solutions that require special carriers.

[0057] Optionally, the method further includes: If the priority interruption of in-transit process configuration is enabled, it is determined whether the code of the material to be transported in the delivery strategy and the code of the target to be recycled in the reverse logistics strategy are consistent.
