Abstract

PURPOSE:To enable safety conveyance into an automatic warehouse including shelves on which large and small cargoes are stored, respectively, after being discriminated from each other, by providing a cargo discrimination means for judging whether each cargo is large or small, to effectuate the conveyance into the warehouse on the basis of the result of the comparison of the output of the discrimination means and the size of the shelf on which the cargo is to be stored. CONSTITUTION:A cargo to be stored in a warehouse is transferred to a prescribed position on a conveyed-in cargo rest 8. If the cargo is a large one 10, both photoelectric switches 12, 13 are put in a state of cargo detection. If the cargo is a small one 11, only the switch 12 is put in the state of cargo detection. The outputs of the switches 11, 12 are applied to a cargo size discrimination circuit 16 so that judgement signals 21 are sent from the circuit to a comparison circuit 22, which compares the signal with a cargo size signal 20 based on a storage shelf position setting card 17 put in a card reader 18. Only when it is judged that the compared signals are coincident with each other, a crane operation permitting signal 23 is applied to a crane controller 19 to operate a crane 1 including a vertically moving carriage 5 and a fork 6 movable in and out, to place the cargo in the warehouse.

Description

[Detailed Description of the Invention] The present invention provides automatic warehouse equipment, especially automatic warehouse equipment that has shelves for separately storing human-sized items and small items, and a human-based storage area. This relates to a method for receiving 11 rods.

The warehousing work number in automated warehouse equipment, (the worker's keyboard and card insertion are set by the user). "The second load was taken to the crowded My River lane, L was 111'

a, 20-・) f, (In an automated warehouse, as mentioned above, when shelves are used to distinguish between people R1!rl and small people ?f r'+j, Even though the cargo to be stored is large, the set storage shelf + ty position is the shelf for storing small cargo, or vice versa.
4' Even though the load to be loaded is a small load, if the set receiving shelf position is the shelf position for storing large loads, the load may fall from the shelf or the crane's load transfer fork may fall off the shelf. A very dangerous situation is expected, such as an excessive amount of ¥500.

The present invention proposes a loading method that can always safely store large and small loads on predetermined shelf positions without causing the above-mentioned dangerous situations.

Hereinafter, one embodiment of the invention will be explained based on the attached illustrative drawings. In FIGS. Travel through the passage rcs 4 with the loading/unloading crane at J+-j, and place the racks 2. This is a conventionally well-known device in which the A-ri (+111-\ also for loading and unloading which can be moved in and out) has no stages. The home position is set at the 11th position of the aisle 4. An example of the 7th floor aisle 4.

(For any small size 11 with the depth to be stored in the JIS delivery shelf 6, place the end of the load on the aisle 4 side in the I section on the aisle 4 side of the R receiving IJ stand 8.) Support in a mated state 1
This cargo receiver has a large front 10-fold rack supported on a platform 8, and a small cargo 11 on the side 4 of the aisle. light? 1) A photoelectric switch 15 for detecting the curve of the side edge of the load 113 is installed 11. ing. 14,15

As shown in FIG. 3, the one-sided crane 1 for handling people is operated by a 1/2 crane control device by inputting the storage rack (-γ installation practical car) 11 to a card reader 18 installed in the 1/-ton. 19 is automatically created 11J I-, and the car 1゛1
The shelf position and warehousing cargo receiver set in step 7 are automatically operated so that the large cylinder 10 or the small cylinder 11 on the platform 8 can be placed normally.

According to the configuration described in section 2, the large-sized goods 11o or the small-sized goods 11 to be received are transferred to a predetermined position on the platform 81- by using a forklift, conveyor, or other appropriate means. In the case of the cylinder 10, both photoelectric switches 12 and 15 are in the load detection state, and in the case of the small front 11, there is a stripe where one of the photoelectric switches 12 is in the load detection state. The target load is large cylinder 1
A determination signal 21 is output to determine whether it is the small front 11. On the other hand, the information recorded in the corresponding car l°17 is changed to Jλ-f by sending the corresponding previous warehousing side 1w setting car 1' 17 to the card reader 18.

According to U, the receiving cargo is placed on the large cylinder 10 or the small front 11 on the stand 8 at the receiving shelf position set by the car 117, that is, the selected empty shelf in the large cargo storage shelf 2 or the small cargo storage shelf. Position-1 is automatically operated by the crane control device 19 to move the crane. If the content of the cargo size determination in the re-discrimination signal 20.21 is not specified, then the cargo receiving for warehousing is determined based on the size of the cargo supported on the platform 8"2 and the size of the cargo supported on the car 1"2. If the shelf size of the storage rack position set by
The crane 1 is automatically operated by operating the crane control device 19.
I can't do it. In case of such abnormality, abnormality display]
It is also possible to configure the steps (lamp, buzzer, etc.) so that each hit is 1;'c 1j.

At the time of unloading from shelf 2 or the inside of the container, let the card that sets the device for exiting the shelf to car 1, league-10,
By pressing the start button of the crane control device 19,
The crane 1 is automatically operated by the control device 19, stored at the set shelf position, and how many large front 10 or small front 11 cranes are there for access? ” - will be disciplined once.

In the embodiment, the storage shelf position can be set by the car 1 (17), but it can also be set by operating the numeric keypad on the y line. In addition, although the shelves 2 for storing large loads and the shelves 6 for storing small loads were installed side by side, 1
There is a large front storage shelf position and a small front storage shelf position in the two fences. The displacement means for determining the difference may have any configuration.

The present invention was carried out as in the above embodiment.1! B) A type of equipment that distinguishes between large and small items (equipped with storage shelves and an entry/exit crane) - In automated warehouse equipment, the crane receives and receives cargo. The cargo receiver is supported on the same table.It is determined whether it is a large load or a small load. and comparing the discrimination result of the cargo discrimination means with the size of the fence to be warehoused determined from the warehouse position setting when the crane is automatically operated;
・It is specially recommended that the above-mentioned crane be automatically operated only when the crane is in operation to carry out the warehousing work. It is possible to avoid the dangerous situation of being put away by someone else, and to always safely and automatically move the cargo to a shelf position of the appropriate size.

In addition, in the actual example, an independent circuit 16.22 is shown, and the same function as the circuit 16.22 is programmed into the Microb Y Shise Solar used as the crane control device 19 or the Microb L1 processor installed separately. It is also possible to implement
