Description

[Detailed Description of the Invention] [Summary] This is a method for transferring stored items when there is room for loading a plurality of loading means such as buckets stored in an automated warehouse. By inputting the number and reloading the designated number of buckets in descending order of loading rate, the selection can be made quickly, saving labor and time.

[Industrial application field]

The present invention relates to a method for transferring stored goods in bucket carts with sufficient loading capacity, for example, in an automated warehouse for storing bucket carts loaded with stored goods, and in particular, it is possible to quickly select bucket carts with a large transloading capacity, thereby saving labor and time. This relates to the storage transshipment system.

In recent years, automation of warehouses has progressed, and in particular, automated warehouses in which buckets and pallets are automatically transported, stored, and unloaded using cranes have become widespread.

In such automated warehouses, transshipment is performed when there is room for loading the same stored items in buckets, etc., and there is a need for a method to quickly select buckets for transshipment. .

[Problems to be solved by conventional technology and invention]

The warehouse staff determines from the receipt/output slips that there is more room for loading in the buckets in the automated warehouse, and reloads the stored items in the buckets.

In the reloading work, the warehouse staff looks at the shelf list and selects multiple buckets with low capacity capacity, that is, multiple buckets with large storage capacity, and unloads them, transfers other stored items to one bucket, reloads it, and stores it empty. Place the old bucket in the empty bucket storage area.

Therefore, there is a problem in that it takes a lot of manpower and time, and it is difficult to perform thorough reloading until the storage efficiency of the bucket is sufficiently increased.

[Means for solving problems]

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

In the figure, 5 is a calculation unit that calculates the loading rate when the loading means is in storage and when the loading margin of the loading means changes; 7 is the product name code of the stored items, the storage position of the loading means, and 8 is an input instruction section for inputting the number of loading means to be transshipped and the product name code of the stored items to be transshipped; 9 is a storage data file for storing the loading ratio; This is a selection unit that selects a specified number of loading means for the corresponding storage items from 7 in descending order of loading ratio.

Therefore, the loading means selected by the selection section 9 is configured to be delivered.

[Effect]

When the loading means enters the warehouse or when the loading rate of the loading means changes, the loading rate is calculated by the calculating section 5 and is filed together with the data of the corresponding stored items in the storage data file 7.

When transshipping, input the transshipment instruction, the product name code of the stored items to be transshipped, and the specified number of loading means from the input instruction unit 8, and the selection unit 9 selects the loaded items with the corresponding stored items from the storage data file 7. A specified number of means are selected in descending order of loading rate.

By taking out the loading means and reloading based on this selection, the selection can be made quickly, labor and time can be saved, and the storage efficiency of the loading means can be easily increased.

Hereinafter, one embodiment of the present invention will be described with reference to the block diagram of FIG. 2 and the flowchart of FIG. 3. 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 4 controls each section and the keyboard 8.
a) Or, based on a loading/unloading command from a control center (not shown), the crane 3 performs the normal loading/unloading operation of the bucket 2 loaded with stored items 1, and also performs the reloading operation when the reloading command switch 83 is pressed. It has the function of carrying out the operation of loading and unloading the bucket 2 for storage and updating of the stored data file accompanying the loading and unloading.

The calculation unit 5a calculates the update data of the storage data due to storage and retrieval, and also stores the volume per unit of storage items 1 for each product number, and calculates the number of storage items 1 loaded in the storage buckets 2. It has a function to calculate the loading rate from the warehousing and to calculate changes in the number of stored items 1 and the number of pallets due to unloading and reloading.

The rank setting unit 6 includes a loading rate rank file as shown in the table below, and has a function of setting a loading rate rank to the loading rate calculated by the calculating unit 5a.

Loading rate (%) 0-20 21-40 41-60 Rank 1 2 3 Loading rate (%) 61-80 81-100 Rank 4 5 The storage data file 7a is for each item number of stored items 1 stored in the warehouse. This is a memory in which the number of stored pallets, the number of pallets, the shelf position, and the stacking margin rank are stored.

The keyboard 8a is an automatic warehouse start/stop button,
A data input button 81, a print instruction button 82 for instructing printing of data stored in the stored data file 7a, a transshipment instruction switch 83, and a drive instruction button 84 for loading and unloading the bucket 2 are provided. When doing so, press the transshipment instruction switch 83.
After repeating the above steps, the user inputs the product number of the stored object 1 to be transshipped and the predetermined number of buckets 2 loaded with the stored object 1 using the data input button 81. Here, the predetermined number is a number specified in order to complete the transshipment within a predetermined time since the transshipment is carried out by a warehouse staff.

The selection unit 9a has a function of selecting a predetermined number of buckets 2 of the corresponding storage items 1 from the storage data file 7a in descending order of loading rate rank when an input instruction is given through the keyboard 8a.

The display 10 displays data inputted from the keyboard 8a, data on the stored items 1 that are being loaded and unloaded, and data such as the address of the selected bucket 2 to be transshipped.

The printer 11 prints out data sent from the storage data file 7a when the print instruction button 82 is pressed.

The crane drive control unit 12 is activated by a start command from the keyboard 8a, and controls the bucket 2 according to the normal loading/unloading operation command, the bucket 2 to be transshipped selected by the selection unit 9a, and the bucket 2 after transshipment. Crane 3 according to the address of

With such a configuration and function, the method of reloading the stored items 1 in the bucket cart 2 with room for additional storage will be explained using the flowchart shown in FIG. The data in the file 7a is printed out by the printer 11.

The warehouse staff selects the product number that requires transshipment and the number of buckets based on the printed data.

Therefore, the transshipment instruction switch 83 is repeatedly operated, and the data input button 81 is used to input the product number and the number of buckets to be transshipped.

Then, the buckets 2 of the corresponding stored items 1 are selected from the storage data file 7a in descending order of loading rate rank and sent to the crane drive control section 12, where they are sequentially delivered to the reloading location.

When the bucket carts 2 are taken out, the warehouse staff starts reloading, and the bucket carts 2 that have been stacked up until there is no more room are stored by pressing the drive instruction button 84.

The specified number of bucket carts 2 that have been sequentially taken out are reloaded and each is put into storage.

The bucket codes of the incoming buckets 2 and the empty buckets 2 are read by sensors (not shown), and the number of buckets is changed and the number loaded on the receiving buckets 2 is calculated, and stored in the storage data file 7a. data will be updated.

Then, the product number and bucket number to be transshipped next are input, and the transshipment is performed.

By specifying the product number and bucket based on the stored data printed out in this way, it is possible to select buckets 2 in descending order of loading rate rank for reloading, allowing the work to proceed quickly and saving time. It is possible to save money, and to easily improve the storage efficiency of the bucket bag 2.

The above example is an explanatory diagram of the case where the loading rate is ranked, but the storage data file 7a is used as the loading rate.
Of course, it is also possible to store the buckets 2 and unload them in order of loading, starting from the bucket 2 with the lowest loading rate.

In addition, although the case of an automated warehouse has been explained as an example, the same effect can be obtained by applying it to a warehouse where loading and unloading is performed manually, and where reloading is performed by checking the shelf list to check the storage space in the bucket 2. can get.
