Abstract

PURPOSE:To improve efficiency of work and space by providing a safety door device, a data indicator and a work completion switch at the work face side of a containing shelf and a throw-in/picking shelf splitted into two, then transmitting data upon completion of work to a host computor. CONSTITUTION:A work 1 contained in a containing shelf 10 is moved through a stacker crane 2 to a picking shelf 11, and throwing/picking content is indicated on an indicator 16 upon completion of movement, then an illumination push button switch 17 is lighted to indicate waiting state of picking. When the shelf 11 is fully occupied and throwing/picking is waited, a worker performs throw-in or picking work of product collectively, In other word, the worker opens a safety door 14 in front of the shelf then throws in or picks a pallet or a bucket according to the content of the indicator 16, thereafter depresses a switch 17 to inform the data to a host computor. Consequently, lamp in the switch 17 unlights and a command for moving the work 1 in the shelf 11 to the containing shelf 10 is outputted to the crane 2.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a three-dimensional automatic warehouse.

(Prior Art) FIG. 4 shows a plan configuration diagram of a conventional three-dimensional automatic warehouse that stores and stores articles on pallets or packets.

Pallets or packets to be input and picked (hereinafter referred to as workpieces 1) are carried out from the shelves 3 to the unloading station 4 by the stacker crane 2, and are arranged on the unloading side of the loop conveyor 5. Here, the worker inserts or picks articles into a pallet or packet according to the input/picking instructions from the CRT 6. After that, by inputting input or picking completion input to CRT6,
The workpiece 1 is transported to the storage station 7 of the loop conveyor, and then re-stocked onto the shelf 3 by the stacker crane 2.

The above control is performed by a separately installed host computer.

(Problems to be Solved by the Invention) In the conventional configuration described above, the loading/unloading cycle time of the stacker crane 2 is as long as 1 to 2 minutes, so the workpieces 1 are generally unloaded onto the multiple loop conveyor 5. We have adopted a method in which items are loaded and picked all at once when they are placed. For this reason, it is necessary to increase the number of workpieces on the loop conveyor 5 in order to improve the loading and picking efficiency of workers, and as a result, the loop conveyor 5 becomes larger and the investment efficiency decreases due to the decrease in space efficiency. Be strong.

Furthermore, in order to perform loading and picking all at once, CRT
6) There is also the problem that the number of displayed items increases, leading to errors in inputting and picking by workers.

The present invention has been made in consideration of the above points, and its purpose is to provide a three-dimensional automatic warehouse that makes it possible to improve the efficiency and space efficiency of article loading and picking operations, and to prevent work errors. be.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention provides a three-dimensional automated warehouse in which works stored in the shelves are carried in and out using a stacker crane. It is divided into a storage shelf and a loading/picking shelf, and a safety door device, a data display, and a work completion switch are installed on the work surface side of the loading/picking shelf, and the operation of the work completion switch is The accompanying data may be configured to be transmitted to a host computer that controls the operation of the stacker crane.

(Function) With the above configuration, the work stored in the storage shelf is transferred to the loading/picking shelf by the stacker crane under the control of the host computer, and upon completion of the movement, the contents of loading/picking are displayed on the data display. The worker opens the safety door device, inserts or picks articles according to the display on the data display, and then presses the completion pushbutton switch 17 to notify the host computer that the work has been completed. As a result, the host computer issues a command to the stacker crane 2 to transfer the workpiece from the input/picking shelf to the storage shelf.

(Example) Examples will be described based on the drawings.

FIG. 1 is a front view of a three-dimensional automated warehouse showing the configuration of the present invention. The shelves of the three-dimensional automatic warehouse are divided into storage shelves 10 and loading/picking shelves 11. The storage shelf 10 minimizes the space in the height direction of the work 1 in order to improve storage efficiency.

Further, the loading/picking shelves 11 are configured in multiple stages at intervals necessary for picking or loading articles in pallets or packets.

Next, details of the loading/picking shelf 11 will be explained.

FIGS. 2 and 3 are a front view and a plan view showing details of the input/picking shelf 11, respectively.

The shelf is composed of a column 12 and a shelf board 13 fixed to the column 12, and the workpiece 1 is placed on the shelf board 13.

On the other hand, a safety door 14 is installed in each column on the work surface side of the shelf.
In addition to disposing a limit switch 15 that operates in conjunction with the safety door 14, a loading/picking display 16, a loading/picking indicator 16,
An illuminated push button switch 17 for completing picking is provided.

The above configuration is controlled by a separate host computer as follows.

The workpiece 1 stored in the storage shelf 10 is moved to the loading/picking shelf 11 by a stacker crane 2 (not shown), and upon completion of the movement, the contents of loading/picking are displayed on the display 16, and a display waiting for loading/picking is displayed. The illuminated pushbutton switch 17 is turned on.

When the loading/picking shelf 11 is almost full and the items are waiting for loading/picking, the worker performs loading or picking work all at once.

The operator opens the safety door 14 on the front of the shelf, inserts or picks items onto a pallet or packet according to the contents of the input/picking display 16, and presses the pushbutton switch 17 to indicate the completion of the work. will be notified of the data. In response to this notification, the lamp of the pushbutton switch 17 is turned off, and a transport command is issued to the stacker crane 2 to move the workpiece 1 on the loading/picking shelf 11 to the storage shelf 10. In addition, the safety door 14 is attached with a limit switch 15 that is linked to the opening and closing of the safety door 14, and when the safety door 14 is open, an interlock is provided to stop the fork operation of the stacker crane 2 relative to the target shelf. Consider safety.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to efficiently load and pick articles, and there is no need for expensive loop conveyor equipment, and the equipment space is not large.

It is possible to provide an automated warehouse that can prevent worker input and picking errors.
