Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] A warehouse replenishment system using both first and second warehouses, wherein the number of stored first warehouses stored in storage means and the stored items stored in storage means The necessity of replenishment to the first warehouse is discriminated by the discriminating means from the standard storage number and the standard storage ratio of No. 1, and when the replenishment is required, the number of requested delivery is issued from the second warehouse, and then from the second warehouse. By instructing the number of stored items to be replenished to the first warehouse, the amount of work can be reduced, and the efficiency of the storage rack of the pallet on which the stored items are loaded can be increased.

[Industrial application field]

The present invention relates to a warehouse in which a warehouse is used in combination with a primary warehouse, for example, a flat warehouse, and a secondary warehouse, for example, an automated three-dimensional warehouse (hereinafter referred to as a three-dimensional warehouse) into and out of which a warehouse or the like is loaded and unloaded. The present invention relates to a warehouse replenishment system that can reduce the number of pallets loaded with stored items and improve shelf efficiency.

In recent years, warehouse automation has progressed, and in particular, multi-storey warehouses in which pallets are automatically transported by a crane to be stored / shipped have become widespread. In this case, a warehouse worker is adjacent to the multi-storey warehouse and near the entrance / exit gate. It is often used in combination with a flat warehouse that is loaded and unloaded. In such a warehouse, a method that can reduce the replenishment work from the three-dimensional warehouse to the flat warehouse is desired.

[Conventional technology]

Generally, in the case of a warehouse in which a flat warehouse and a three-dimensional warehouse are used together, in the flat warehouse, the stored items are loaded on a pallet and stored on a shelf at a predetermined address. Therefore, the warehousing work is carried out by the warehouse staff up to the shelves at the address, the number of warehousing commands is issued from the pallet, and the remaining number is stored on the pallet.

In a three-dimensional warehouse, the lower surface of a pallet carrying stored items is held by a crane arm for transportation. Therefore, in the case of warehousing, the pallets of the commanded number are carried from the shelf to the unloading port by the crane, the commanded number of unloading is issued, and the remaining number is re-loaded into the shelf again while being mounted on the pallet.

In this case, when the same article is stored in the flat / three-dimensional warehouse, the delivery warehouse is determined by the following formula. In other words, 1) number of orders issued ≤ number of storage in flat warehouse → output from flat warehouse 2) number of commands issued from warehouse> number of storage in flat warehouse → three-dimensional warehouse 〃

Since the work of leaving a flat warehouse is easier and quicker than issuing from a multi-storey warehouse, when stock in the flat warehouse decreases,
At the discretion of the warehouse staff, an appropriate number of stored items are loaded from the three-dimensional warehouse onto pallets and shipped to the flat warehouse to prepare for a shipping instruction.

[Problems to be solved by the invention]

As described above, in the conventional method, inventory replenishment to a flat warehouse is carried out by loading the number of replenishments from a multi-level warehouse onto pallets and replenishing it to the flat warehouse. However, there is also a problem in that it is not appropriate, and further, the efficiency of the shelves is reduced by the pallet on which a fraction of the stored items is mounted.

[Means for solving problems]

 FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, 3 is the number of stored items stored in each of the first and second warehouses, the standard number of stored items stored in the first warehouse, and the criterion for replenishing the stored items in the first warehouse. Storage means for storing the standard storage ratio, which is the storage ratio of the storage capacity of the first warehouse stored in the storage means 3, the standard storage number of the stored contents, and the standard storage ratio at the time of leaving the second warehouse. Is a determining means for determining whether or not it is necessary to replenish the first warehouse.

Therefore, as a result of the discrimination by the discriminating means 4, when the replenishment is required, the number of the mounting means to be moved and replenished from the second warehouse to the first warehouse is instructed.

[Action]

At the time of leaving the second warehouse, the discriminating means 4 determines whether the first warehouse is replenished from the stored number of the first warehouse stored in the storage means 3, the standard stored number of stored items, and the standard storage ratio. Determine necessity. That is, the storage ratio obtained by dividing the storage count by the standard storage count is compared with the standard storage ratio, and when it is determined that the storage ratio is smaller than the standard storage ratio, the standard storage number and the storage The difference from the number is commanded from the second warehouse to the first warehouse. Replenishment work is performed based on the command. In this way, the workload of the staff is reduced,
The efficiency of storage shelves can be improved.
