Abstract

PURPOSE:To simplify storing and custody of articles in various heights by determining the number of storage division units required to store articles in a warehouse and retrieving positions of storing which satisfies the number from a management file. CONSTITUTION:Labels L which magnetically record item codes f, g, heights data h1, h2, indicating heights of articles H1, H2, are affixed to articles F, G and one of the articles is put on the pallet P of a crane 2, after the label L is read by a reading part 9 at storing. Each data read by the reading part 9 is fed to a discriminating part 10 of a processing unit 4. If the height data is less than the prescribed height of a storing shelf which is a storage divsion unit, the item code of the corresponding article is posted to a retrieving part 11 and the article is stored on a prescribed empty shelf Tn in conformity with a management file 5. On the other hand, if the height data is more than the prescribed height h, a doubled height data 2h, together with the item code are posted to the retrieving part 11 and two adjacently positioned storing shelves are retrieved and the article is stored there.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in an automatic warehouse system that automatically stores and manages articles in a warehouse.

In automated warehouse systems, articles are stored in predetermined units of columns provided within the warehouse, and it is desired to realize a warehouse system that can store and manage articles of different load heights.

[Conventional technology]

This will be explained using a diagram of a conventional example of an automated warehouse system. Second
The figure is a block diagram illustrating a conventional example.

In the warehouse 1, there are storage shelves T1 having a predetermined height and a predetermined storage capacity.
~Tn is provided. For example, load height ■.

When the article AY is placed on the pallet P of the crane 2 and the control key MY on the keyboard 30 is pressed, the processing section 4 searches five management files, finds an empty shelf (for example, T), and sets this shelf number Tl to the crane control section 6. Notice.

The crane control unit 6 sends a start command C to the crane 2. As a result, the crane 2 moves to the front of the storage shelf number T in the warehouse 1, and the object ^'pA and the storage rack P are moved (raised) to the shelf position number T1 and stored.

As described above, in the automated warehouse system, the goods are automatically stored by simply placing the goods on the pallet l-P of the crane 2 and inputting the fOIJ4 command. When the load amount is H2, the sensors S1 and S! is activated, and a detection signal is sent to the processing section 4. In addition, sensor S.

and S, the loading height H) of the article is storage shelf T1''''-'fn
The sensor is installed to output a detection signal Dy when the height is higher than a predetermined height.

In response to the detection signal D, the processing unit 4 sends an alarm signal E1 to the display unit 7, and displays "Unable to enter the warehouse", and also sends an alarm signal E1 to the display unit 7.
2, send it to buzzer 8, make it sound, and notify the operator.

[Problem that the invention seeks to solve]

As mentioned above, conventional automated warehouse systems have problems such as not being able to store goods that exceed the height of the storage shelves in the warehouse, and being unable to store and manage goods with a wide variety of cargo heights.

[One-stop solution to the problem] The second problem is that the warehouse stores goods in units of storage compartments with a predetermined height, and the rational file that manages the storage status of the goods in the warehouse. In a warehouse system having an article conveyor 477, the load height data indicating the height τ of the article is input manually, and then the input load height data is input. The device is equipped with a means for comparing the length of the article, and compares the input load height data with the predetermined length when storing the article, and determines the length of the storage area required for accommodating the article. The self-destruction storage system of the present invention determines the number of storage units M, retrieves the storage location from the management file 61, and stores the nil storage location in the storage location. resolved.

[Effect]

As described above, the present invention provides a warehouse system in which goods are stored and managed based on 11 units of storage area with a predetermined height. This makes it easy to store and maintain a wide variety of items with a wide variety of loading heights.

〔Example〕

Hereinafter, the present invention will be explained with reference to seven drawings. FIG. 1 is a block diagram illustrating one embodiment of the present invention.

In FIG. 1, a label L is affixed to the articles (F, G), and an item coat (f, g) is attached to this label L.
) and load height data (h+, h*) indicating the load height (U+, Hz) of the article are magnetically recorded.

In the case of storage, for example, the label LY of the article F is read by the reading section 9, and then the article FY is placed on the pallet P of the crane 2.

The item code f and load height data h read by the reading section 9 are sent to the processing section 40 and the discriminating section 10. Discrimination part 1
0 notifies the item code fY search unit 11 when the load height data h is less than or equal to the predetermined height of the storage shelf. Note that a storage shelf refers to a storage compartment unit having a predetermined height bY.

When the search unit 11 searches the management file 5 and detects an empty shelf, for example, TnY, the search unit 11 searches the management file 5 for the I
Column Inventory information Q1 Similarly, item data f1 in J column Also, K
After recording the numerical value "1" in the column, the shelf number becomes Tn and is notified to the lane control unit 6.

As a result, the crane control unit 6 issues a start command to the CY crane 2.
By sending the article F to the pallet P,
It is stored in storage shelf Tn.

On the other hand, when an article G with a load height H2 (however, t, 2 h')
After reading it, place it on crane 2's pallet (PK).

The item code g and cargo height data h2 read by the reading section 9 are sent to the processing section 40 and the discriminating section 10, where they are discriminated. When the determining unit 10 confirms that the load height data h2 is thicker than the predetermined height of the storage shelf but smaller than the double length height 2h, the determination unit 10 uses the double length height data 2h, the item code g”ir, and the search unit Notify 11.

The search unit 11 searches the management file 5 for a storage shelf in which two empty shelves exist consecutively, based on the double height data 2h. For example, when the storage shelves with numbers T1 and T2 are "vacant", the search unit II stores the inventory information Q1 in the ■ column of number 1 and the item data g in the J column.

The numerical value "1" is recorded in the second column, and the occupancy information ZY is recorded only in the I column of number T1. This occupancy information Z is information indicating that the storage shelf T1 is occupied by the article G stored in the storage shelf T2 and cannot be stored. After that, the search unit 11 finds the shelf number T! The crane control unit 6 is notified.

The crane control unit 6 issues a control command CY, moves the crane 2, and stores the articles GY and pallets P at the positions of shelf numbers T1 and Tn.

As described above, in the present invention, the discriminating section 10 determines the load height of the goods to be warehoused, determines the shelf position lN, 'Y in accordance with the load height, and allows the goods to be stored in the warehouse.

〔Effect of the invention〕

The present invention not only solves the problem of not being able to store goods due to load height restrictions in a storage system with a wide variety of loads, but also has the effect of improving warehouse storage efficiency.
