Description

[Technical Field]

[0001] This invention relates to a furniture raw material automated warehouse management system. [Background Technology]

[0002] Currently, panel furniture manufacturers typically use the following raw material specifications: 48 feet 2440*1220*920 / 1025mm (50 layers (18mm) / 40 layers (25mm)), 49 feet 2745*1220*920 / 1025mm (50 layers (18mm) / 40 layers (25mm)), and 79 feet 2800*2080*620mm (30 layers (18mm) / 24 layers (25mm)). The large size and weight of the panels, coupled with the large quantity stored, lead to difficulties in moving and transporting the raw materials in warehouses. This hinders timely feeding of materials to cutting equipment and results in significant space requirements, ultimately leading to low production efficiency. As order volumes increase, the lack of standardized raw material management becomes even more pronounced, making transparent and efficient management difficult. [Summary of the Invention]

[0008] The furniture raw material automated warehouse management system described above is characterized in that: when the host computer detects that there are enough idle and adjacent raw material pre-sorting warehouse locations and that there are idle stacker cranes, the host computer controls the idle stacker cranes according to the production task to prioritize screening raw materials from the raw material storage warehouse locations according to the first-in-first-out (FIFO) principle or the designated batch of raw materials, and then transports the screened raw materials to the adjacent raw material pre-sorting warehouse locations for storage; when the host computer detects that there are not enough idle and adjacent raw material pre-sorting warehouse locations and that there are idle stacker cranes, the host computer controls the idle stacker cranes according to the production task to prioritize screening raw materials from the raw material storage warehouse locations according to the first-in-first-out (FIFO) principle or the designated batch of raw materials, and then transports the screened raw materials with the same production task to the raw material pre-sorting warehouse locations for mixed storage.

If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0026] like Figure 1 As shown, a furniture raw material automated warehouse management system includes a raw material receiving end 1, a raw material dispatching end 2, a pallet storage area 3, and a stacker crane 4 for moving and transferring raw materials and pallets between the areas. Between the raw material receiving end 1 and the raw material dispatching end 2, there are sequentially arranged a raw material storage area 5, a raw material pre-sorting area 6, and a gantry area 7. A raw material return channel 8 is provided between the gantry area 7 and the raw material storage area 5. The raw material storage area 5 has multiple raw material storage locations 51. The raw material pre-sorting area 6 has multiple raw material pre-sorting locations 61. The gantry area 7 has multiple gantry sections 71. The gantry sections 71 have multiple gantry buffer locations 711, and a stacker crane 4 is used to move raw materials placed on the gantry buffer locations 711 out of the warehouse. The system also includes a gantry 712, which controls the stacker crane 4 to move the incoming raw materials from the raw material receiving end 1 to the raw material storage location 51, controls the stacker crane 4 to move the raw materials in the raw material storage location 51 to the raw material pre-sorting location 61 according to the production task, controls the stacker crane 4 to move the raw materials in the raw material pre-sorting location 61 to the gantry buffer location 711 according to the production task, controls the gantry 712 to move the raw materials in the gantry buffer location 711 to the raw material exit end 2 for exit according to the production task, controls the stacker crane 4 to move the remaining raw materials in the gantry buffer location 711 back to the raw material storage area 5 through the raw material return channel 8 according to the production task, and controls the stacker crane 4 to pick up and put down pallets in the pallet storage area 3.

[0027] like Figure 2As shown, the process of the raw material automated warehouse management system includes raw material arrival, storage location allocation, stacker crane scheduling, outbound pre-sorting, stacker crane outbound scheduling, and surplus material return. Specifically, after the raw materials arrive, the host computer 9 allocates storage locations according to the storage status of the raw material storage location 51 in the raw material storage area 5, and controls the stacker crane 4 to transport the raw materials to the allocated storage locations. The host computer 9 schedules the stacker crane 9 to transport the raw materials required for production from the raw material storage location 51 in the raw material storage area 5 to the raw material pre-sorting location 61 in the raw material pre-sorting area 6 according to the production task. The host computer 9 then transports the raw materials in the raw material pre-sorting location 61 in the raw material pre-sorting area 6 to the gantry buffer location 711 in the gantry partition 71 according to the production task, so that the gantry crane 712 can transport the raw materials in the gantry buffer location 711 to the raw material outbound end 2 opening input channel. The host computer 9 controls the stacker crane 4 to return the remaining raw materials in the gantry buffer location 711 back to the raw material storage area 5. It enables the automatic execution of raw material warehousing, outbound, and inventory operations, facilitates raw material management and rapid material transportation, and enables timely feeding of materials to cutting equipment, thereby improving production efficiency and equipment utilization and reducing equipment waiting time.

[0028] like Figure 3 As shown, when raw materials arrive and need to be put into storage, the raw material storage location 51 is allocated according to batch and raw material specification. By default, raw materials of the same batch and specification are placed in adjacent raw material storage locations 51 to reduce the transfer operation when picking and sending materials out of the warehouse.

[0029] Specifically, when raw materials arrive and the host computer 9 detects that there are enough empty and adjacent raw material storage locations 51, the host computer 9 controls the stacker crane 4 to prioritize the delivery of the arriving raw materials in the same batch and of the same specifications to the empty and adjacent raw material storage locations 51 for storage; when raw materials arrive and the host computer 9 detects that there are not enough empty and adjacent raw material storage locations 51, the host computer 9 controls the stacker crane 4 to prioritize the delivery of the arriving raw materials in the same batch but of different specifications to the adjacent raw material storage locations 51 for mixed storage; when raw materials arrive and the host computer 9 detects that there are not enough raw material storage locations 51, the host computer 9 controls the stacker crane 4 to prioritize the delivery of the arriving raw materials in the same batch and of the same specifications to the empty and adjacent raw material pre-sorting location 61 for storage.

[0030] like Figure 4 As shown, according to the production task, when the stacker crane 4 is idle, the raw materials are selected according to the set first-in-first-out principle or the principle of designated batches, and the raw materials that meet the production task are placed in advance on the raw material pre-sorting storage location 61. The raw materials with the same outbound order are placed in the adjacent raw material pre-sorting storage location 61 of the raw material pre-sorting area 6 to improve the speed of raw material outbound operation.

[0031] Specifically, when the host computer 9 detects that there are enough idle and adjacent raw material pre-sorting storage locations 61, and there is an idle stacker crane 4, the host computer 9 controls the idle stacker crane 4 to prioritize screening raw materials from the raw material storage location 51 according to the first-in-first-out (FIFO) or designated batch of raw materials, and then moves the screened raw materials to the adjacent raw material pre-sorting storage location 61 for storage; when the host computer 9 detects that there are not enough idle and adjacent raw material pre-sorting storage locations 61, and there is an idle stacker crane 4, the host computer 9 controls the idle stacker crane 4 to prioritize screening raw materials from the raw material storage location 51 according to the first-in-first-out (FIFO) or designated batch of raw materials, and moves the screened raw materials with the same production task to the raw material pre-sorting storage location 61 for mixed storage.

[0032] Furthermore, during the pre-sorting of raw materials, the host computer 9 controls the idle stacker crane 4 to screen raw materials from the raw material storage location 51 according to the raw material production sequence in the production task.

[0033] like Figure 1 As shown, the gantry area 7 near the raw material outbound end 2 has two gantry sections 71, and each gantry section 71 has two gantry buffer positions 711 for the gantry 712 to perform picking operations on the raw materials. Therefore, the stacker crane 4 needs to be scheduled, including raw material outbound, residual material return, pallet transportation, and orderly transportation.

[0034] On the other hand, when scheduling stacker crane 4, it is necessary to avoid a situation where stacker crane 4 is overloaded while gantry crane 712 has no raw materials available for picking. Therefore, such as... Figure 5 As shown, when picking raw materials from the gantry 712 picking platform, priority should be given to allocating the picking tasks for the gantry 712. Specifically, when the host computer 9 has production tasks to be executed and detects that there is an idle gantry cache storage location 711, the host computer 9 prioritizes generating an outbound instruction and prioritizes controlling the stacker crane 4 to move the raw materials stored in the pre-sorting storage location 61 to the gantry cache storage location 711 according to the production task; when the host computer 9 has no production tasks to be executed or detects that there is no idle gantry cache storage location 711, the host computer 9 prioritizes controlling the stacker crane 4 to perform raw material inbound, raw material outbound, and raw material transfer operations in sequence.

[0035] Furthermore, the host computer 9 prioritizes controlling the stacker crane 4 to move the raw materials stored in the pre-sorting storage location 61 to the gantry cache storage location 711 according to the raw material production sequence in the production task.

[0036] When the material is being shipped out, the host computer 9 controls the gantry 712 to move the raw materials stored in the gantry buffer storage location 711 to the material output end 2 opening input channel according to the production task.

[0037] Furthermore, the host computer 9 controls the gantry 712 to move the raw materials stored in the gantry buffer storage 711 to the material output end 2 opening input channel according to the raw material production sequence in the production task.

[0038] For example, the first task performed by the first gantry 712 might only require one stack of raw materials, occupying one gantry buffer slot 711 of the first gantry 712, while the other gantry buffer slot 711 is idle. In this case, the host computer 9 will allocate the idle gantry buffer slot 711 to another task. Thus, the stacker crane 4 needs to deliver the raw materials for two tasks to the gantry buffer slot 711 of the first gantry 712. After picking up the first task, the first gantry 712 can immediately begin picking up the second task; similarly, the second gantry 712 can do the same. In this way, while the two gantry cranes are working, the stacker crane 4 can be controlled to perform other tasks such as receiving, dispatching, raw material return, and pallet transport based on its status. When a gantry buffer slot 711 is found to be empty, it checks for any unexecuted dispatching tasks and prioritizes the dispatching of raw materials, thereby improving equipment utilization and reducing equipment waiting time.

[0039] In this case, when raw materials are stored in raw material storage location 51 or raw material pre-sorting location 61 for a long time, it is necessary to cover the top of the raw materials with pads to prevent dust from falling onto the top layer of raw materials; at the same time, when it is necessary to stack multiple layers of raw materials or mix raw materials, it is also necessary to cover them with pads to separate them. Therefore, it is necessary to set up a pad storage area 3 and control the stacker crane 4 to pick up and put down pads according to actual usage needs.

[0040] The host computer of this system can also receive data from ERP and MES to obtain the required inbound and outbound tasks. Based on the task and equipment status, it generates corresponding control commands such as inbound, outbound, return, transfer, and pallet conveying to control the relevant equipment to perform corresponding operations. This enables the automatic execution of raw material inbound, outbound, and inventory operations, ensuring smooth production, reducing the workload of operators, reducing human resource input, and effectively improving work efficiency.

[0041] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
