Description

[Detailed Description of the Invention] [Summary] This is a warehouse storage method in which multiple types of parts are loaded and stored on a loading means, and parts included in a parts list for each product are loaded together on the loading means to be shipped out. Enables improved efficiency.

[Industrial application field]

The present invention provides a mounting means on which multiple types of parts are mounted.

For example, it relates to a warehouse storage method for storing pallets, and in particular, a warehouse storage method that can increase the efficiency of warehouse retrieval by calling and loading pallets loaded with parts included in the parts list of the same product as the parts to be received. It is related to.

In recent years, automation of warehouses has progressed, and in particular, automated warehouses that use cranes to automatically transport pallets and store them three-dimensionally have become popular.

In such warehouses, a method is adopted in which the pallets that are in storage that have room to be stacked are taken out of the warehouse and the parts that should be put in the warehouse are stacked together. A method is desired.

[Conventional technology]

Multiple types of parts are loaded onto pallets stored in automated warehouses, and the underside of the pallets is held by a crane arm for transportation.

When parts are loaded and stored on pallets, when the parts to be stocked arrive at the warehouse entrance, the stored pallets that can be stacked are called to the warehouse entrance and stacked.

Conventional loading methods only manage the quantity of parts. In other words, the extra stacking margin is determined from the ratio between the number of stored pallets loaded and the maximum number that can be loaded, and if the quantity of incoming parts is within the stacking margin, the pallet is called regardless of the type of parts. The parts are mounted and stored.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional method, if there is room for additional stacking on the pallet, the incoming parts are loaded and stored, so the storage shelves for parts are randomized, and when the parts necessary for the product are to be delivered, each part is Since the pallets are unloaded, it is necessary to unload many pallets, resulting in a problem that the unloading efficiency is poor.

[Failure to solve the problem]

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

In the figure, 7 is storage data of parts stored in the warehouse;
That is, a first storage section stores the part code, the code of the loading means on which the component is loaded, the loading rate, and the shelf address; 8 a second storage section that stores the parts list for each product; The parts list is a list of the parts that make up the product, and when the product is assembled, the parts on the parts list are shipped all at once.

Reference numeral 9 refers to a search unit that searches the second storage unit 8 for a parts list containing the corresponding part based on the part code, and reference numeral 10 refers to a search unit 9.
This selection section selects a code of a mounting means with sufficient loading capacity from the first storage section 7 based on the component code of the component included in the parts list searched by.

Therefore, when a component storage command is issued, the mounting means selected by the selection section 10 based on the component code in the parts list searched by the search section 9 is unloaded and the stored component is loaded.

[Effect]

When the parts to be stored arrive at the warehouse entrance, the search unit 9
searches the second storage unit 8 for a parts list containing the corresponding part based on the parts code, and the selection unit 10 selects the loading of the corresponding part from the first storage unit 7 based on the part code of the part included in this parts list. Select a code for a mounting method with sufficient margin.

By calling up the selected loading means and stacking the stored parts, the parts included in the parts list for each product are stored together, making it possible for the necessary parts to be delivered from the same loading means at the time of shipment. As a result, the number of loading means to be unloaded is reduced, and the unloading efficiency can be significantly improved.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained in the block diagram of Fig. 2 and the block diagram of Fig. 3.
This will be explained with reference to the flowchart shown in the figure.

The same reference numerals indicate the same objects throughout the figures.

In FIG. 2, parts corresponding to those in FIG. 1 are shown surrounded by a chain line.

The main control section 3 controls each section to carry out loading and unloading operations of parts including stacking of parts on pallets 2, and also performs calculations to update stored data due to loading and unloading, and updates stored data in a storage data file 7a. It has the function to perform

The keyboard 4 includes a start/stop button for the automated warehouse, a data input button, a drive instruction button 4a for loading and storing parts 1 on the pallet 2, and a call button 4b for calling an empty pallet 2.
etc.

The display 5 displays data entered from the keyboard 4, the name of the part being stored, the part number, and the quantity.

and the storage address of palette 2 are displayed.

The storage command memory 6 stores storage command data for the parts 1, that is, storage command signals, which are input sequentially from a control center (not shown) or from the keyboard 4.

and stored component data such as component names, component codes, and quantities. Storage command data for a plurality of parts l may be stored.

The stored data file 7a contains the part codes of parts stored in the warehouse and the shelf addresses of the pallets 2.

This is a memory that files storage status data such as extra storage space and stores blank addresses.

The parts list memory 8a is a memory that stores a parts list for each product, and the parts list can be searched using a parts code as a key.

The parts list search unit 9a has a function of searching the parts list memory 8a for a parts list containing a corresponding part based on a part code.

The stacked pallet selection section 10a includes a parts list search section 9.
It has a function of selecting a code of a mounting means that has sufficient loading space for the corresponding component from the stored data file 7a based on the component code of the component included in the component list read out by step a.

The crane drive control unit 11 is activated by a start command from the keyboard 4, and receives a warehousing command sent from the main control unit 3.
That is, the drive of the crane 12 is controlled by address signals and the like that command the unloading and loading of pallets 2 for stacking.

Since it has such a configuration and function, the method of storing the stored object l will be explained with reference to the flowchart in FIG. 3. ■ First, from the control center or keyboard 4,
Part data to be stored is input together with the storage command signal and stored in the storage command memory 6.

■When it is the turn to store the corresponding part 1, the part data to be stored is outputted from the storage command memory 6 by the storage start signal from the main control unit 3 and displayed on the display 5, and the parts list search unit Sent to 9a.

■The parts list search section 9a first searches the parts list memory 8a.
The parts code is sent to the part code, the parts list including the part is searched and read out, and sent to the stacking pallet selection section 10a.

■The stacking pallet selection unit 10a selects a pallet 2 with sufficient loading capacity for the corresponding parts from the storage data file 7a based on the part code of the parts included in this parts list, and sends an address signal for shipping to the crane drive control unit 10. send.

■Thus, the stackable pallet 2 is delivered from the designated address.

■If there is no pallet 2 that has enough room to load the corresponding part, an empty pallet 2 is called up.

(2) Then, the parts 1 to be stored are loaded onto the pallet 2 by the staff member.

■If the number of parts to be stored exceeds the amount that can be loaded and there is a remainder left, the staff member presses the call button 4b of the empty pallet 2 from the keyboard 4 to call up the empty pallet 2 and remove the remaining parts. Mount.

(2) After any pallet 2 has been loaded, it is stored in the specified shelf address by referring to the blank address in the storage data file 7a when the staff member presses the drive command button 4a.

[Phase] Also, the quantity loaded by stacking and the quantity loaded on the recalled empty pallet 2 are calculated by the main control unit 4, and the stored data in the stored data file 7a is updated.

In this way, the parts included in the parts list for each product can be stacked together so that they are loaded onto the pallet 2, so multiple parts can be shipped at once, and the number of pallets 2 to be shipped is significantly reduced. It is possible to improve shipping efficiency.

Although the above example describes the case of an automated warehouse, it can also be applied to a warehouse where warehouses are manually loaded and unloaded, and similar effects can be obtained.

〔Effect of the invention〕

As explained above, according to the present invention, the parts included in the parts list for each product can be loaded on the loading means all at once, so the number of outgoing pallets can be reduced and the outgoing efficiency can be significantly improved. effective.
