Description

Technical Field

[0001] The present invention relates to the technical field of warehouse management methods, and in particular to a sequential material access first-in-first-out method. Background Art

[0002] In lean production management, the first-in-first-out (FIFO) of materials is a basic management requirement. FIFO is conducive to the production of products in a planned sequence in each process, preventing mixed batches and materials, and ensuring the balance of product production cycles. In order to achieve the FIFO function, the existing FIFO method usually requires materials to slide along a sloped slide rail during actual operation, and sometimes personnel are required to carry them.

[0003] The Chinese invention patent with the document number CN101327871A discloses a storage rack used in cable production, which includes a frame; at least one or more racks distributed in the height direction of the frame and fixed to the frame in an inclined state with one end high and the other end low, wherein the lower end of each rack is formed with an outlet for transferring goods to the next rack; a valve hingedly connected to the lower side of the frame, the valve corresponding to the outlet of the last rack in the racks. This technical solution has the disadvantages of complex equipment structure and high production and maintenance costs. In addition, the materials continue to roll on the storage racks, which is easy to damage the materials.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a sequential material access first-in-first-out method to improve the implementation efficiency of the first-in-first-out management method.

[0006] The technical solution of the present invention is as follows:

[0007] The sequential material storage and retrieval first-in-first-out method includes the following steps: S1. Determine the material flow route on the material rack, and the flow route is connected end to end to form a closed loop route; S2. Determine the material flow direction, and the material is stored in the storage location of the material rack in sequence along the flow direction and the flow route; S3. Determine the starting point position, and the starting point can be located at any storage location of the flow route; S4. When storing the material for the first time, store the material at the storage location of the starting point; S5. When storing the material subsequently, store the material in sequence from the starting point position along the flow route and the flow direction, and the stored multiple materials form a continuous and uninterrupted material chain; along the flow route and the flow direction, the end of the material chain is the head position of the material chain; along the reverse direction of the flow route and the flow direction, the end of the material chain is the tail position of the material chain; S6. When taking out the material for the first time, take it out from the storage location of the starting point; S7. When taking out the material subsequently, take out the material in sequence from the starting point position along the flow route and the flow direction.

[0008] The beneficial technical effects of the present invention are as follows:

[0009] (1) The sequential material access FIFO method of the present invention determines the flow direction and the closed-loop flow route, and stores the materials on the material rack in order along the flow route and flow direction; and takes out the materials in order along the same route and direction as the material storage, thus realizing the FIFO function of material access. The method requires less asset investment, is easy to operate and implement, and can realize the FIFO management function of material access in the production workshop at a lower cost.

[0010] (2) Furthermore, during the material storage and retrieval operation, the position of the materials placed on the material rack remains unchanged, and no additional sliding or transportation is required, thereby avoiding the risk of collision that may occur during the sliding process of the materials and eliminating the additional transportation operation load.

[0017] Figure 1 FIG. 1 shows a schematic diagram of the structure of the material rack provided in an embodiment of the present invention. Please refer to FIG. Figure 1 , taking material rack 1 as an example, the sequential material access first-in-first-out method is introduced, which includes the following steps:

[0018] S1. Determine the flow route 2 of the material 4 on the material rack 1, and the flow route 2 is connected end to end to form a closed loop route. On the material rack 1, the flow route 2 can be marked on the material rack 1 by a specific color, text, symbol or light, etc., so that the operator can view it easily.

[0019] S2. Determine the flow direction of material 4, and store material 4 in the storage location of material rack 1 in sequence along the flow direction and flow route 2.

[0020] S3. Determine the starting point location, which can be located at any storage location of circulation route 2.

[0021] S4. When material 4 is stored for the first time, material 4 is stored at the storage location at the starting point.

[0022] S5. When material 4 is subsequently stored, material 4 is stored in order from the starting point along the flow route 2 and the flow direction, and the stored multiple materials 4 form a continuous and uninterrupted material chain. After storing material 4, a storage board 31 is placed at the storage location at the head position of the material chain. The storage board 31 is adsorbed on the storage location by magnetic force, and the storage board 31 can also be fixed on the material rack 1 by other means. After each storage of material 4, the head position of the material chain will be updated, and the storage board 31 will be moved to the new head position of the material chain. Ensure that the storage board 31 is always at the head position of the material chain, and the operator can refer to the storage board 31 to accurately place the material 4 in the material rack 1.

[0023] Among them, along the circulation route 2 and the circulation direction, the end of the material chain is the head position of the material chain. Along the circulation route 2 and the opposite direction of the circulation direction, the end of the material chain is the tail position of the material chain.

[0024] S6. When taking out material 4 for the first time, take out material 4 from the storage location at the starting point.

[0025] S7. When taking out material 4 subsequently, take out material 4 in order from the starting point along the flow route 2 and the flow direction. After taking out material 4, place a take-out kanban 32 at the storage location at the tail position of the material chain. Each time material 4 is taken out, the tail position of the material chain will be updated, and the take-out kanban 32 will be moved to the new tail position of the material chain. Ensure that the take-out kanban 32 is always at the tail position of the material chain, and the operator can refer to the take-out kanban 32 to take out material 4 from the material rack 1. The take-out kanban 32 is adsorbed on the storage location by magnetic force, and the take-out kanban 32 can also be fixed to the material rack 1 by other means.

[0026] Figure 2 The flow chart of the material flow on the material rack in the embodiment of the present invention is shown. Figure 1 and Figure 2 , taking the case where there are 20 storage locations on a material rack 1, the material rack 1 has 4 layers, with 5 storage locations on each layer. The specific implementation method of the sequential material access first-in-first-out method of the present application is as follows:

[0027] Set the starting point to warehouse No. 1, along the circulation route 2 and the circulation direction, the remaining warehouses are warehouse No. 2, warehouse No. 3, and warehouse No. 20 in order. From the starting point, along the circulation route 2 and the circulation direction, 15 batches of material 4 are stored in order. Warehouse No. 1 is stored first, and warehouse No. 15 is stored last. From warehouse No. 1 to warehouse No. 15, the material 4 forms a continuous and uninterrupted material chain. At this time, warehouse No. 15 is the head position of the material chain, and the storage kanban 31 is stored in warehouse No. 15. Warehouse No. 1 is the tail position of the material chain, and the removal kanban 32 is in warehouse No. 1.

[0028] When the 16th batch of material 4 is deposited, the 16th batch of material 4 is deposited in the No. 16 warehouse, and the deposit kanban 31 is moved from the No. 15 warehouse to the No. 16 warehouse. When taking out material 4, the material 4 on the No. 1 warehouse is taken out, and the take-out kanban 32 is moved from the No. 1 warehouse to the No. 2 warehouse.

[0029] When the deposit and withdrawal rates of material 4 are the same, if material 4 is deposited in storage location 20, the deposit kanban 31 is moved to the position of storage location 20. Then material 4 in storage location 5 has also been taken out, and the withdrawal kanban 32 is moved to storage location 6. At this time, storage locations 16-20 are occupied in sequence, and storage locations 1-5 are vacated in sequence. According to circulation route 2 and circulation direction, the 21st batch of material 4 will be deposited in storage location 1, and the deposit kanban 31 is also moved to storage location 1. When material 4 in storage location 6 is taken out, the withdrawal kanban 32 is moved to storage location 7. The above deposit and withdrawal operations are repeated, and the first-in-first-out function of material 4 storage and withdrawal is realized without the need for additional movement or transportation of material 4.

[0030] It can be seen that the above-mentioned sequential material access FIFO method determines the closed cycle flow route 2, and stores the material 4 in sequence along the flow route 2 and the flow direction. Then the material 4 is taken out according to the same route and direction, thus realizing the FIFO function of accessing the material 4. This method only requires less asset investment, is easy to operate and implement, and can realize the FIFO management function of material access in the production workshop at a lower cost.

[0031] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
