Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a stacker storage device that is applied to store articles that do not like dirt during storage.

[Technical background of the invention and its problems]

Generally, when storing items that do not like dirt, such as fuel pellets, in stacker storage, partition plates are installed between each shelf to prevent dirt from falling, and the items are covered with dirt-preventing covers. If partition plates are provided, the space between the shelves becomes large, resulting in poor storage efficiency, and if a dirt prevention cover is provided, automation may fail due to the need to perform the work manually.

Therefore, a technical means was proposed to store the items in a storage box, but in this case, it would be necessary to take the items in and out of the storage box in the process before and after storage, which would increase the number of man-hours. This poses a problem in that it is a hindrance to automation.

[Purpose of the invention]

The present invention has been made in view of the above points, and
The purpose of the present invention is to provide a stacker storage device that automates the storage of articles that do not like dirt and improves storage efficiency.

[Summary of the invention]

The stacker storage device of the present invention includes a stacker storage that has a plurality of shelves and a partition plate that partitions between the shelves and defines a plurality of chambers, and a stacker storage that is provided at the open end of each chamber of the stacker storage. An opening/closing door whose upper part is pivotably supported and closed by its own weight, a stacker crane that runs along the opening side of the stacker storage, a fork device installed on this stacker crane so that it can be raised and lowered, and a pivot of the opening/closing door. It has a mechanism for pushing a portion above the fulcrum and a door opening device for opening an opening/closing door attached to the fork device.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a stacker storage for storing, for example, a lined tray loaded with fuel pellets (grinding bodies), and one end of this stacker storage 1 is connected to the previous process. A loop-shaped conveyor 2 is provided, and a loop-shaped conveyor 3 connected to a subsequent process is provided at the other end. Between the stacker storage 1 and the conveyor 2, there is a loading/unloading station 4.
A loading/unloading station 5 is provided between the stacker storage 1 and the conveyor 3, respectively.

As shown in FIG. 2, the stacker storage 1 is configured with partition plates 7, 7, .
I try to define it. The back side of each chamber 8 is closed by a cover (not shown). As shown in FIG. 1, the stacker storages 1 are arranged at a predetermined interval so that their opening sides face each other. The predetermined interval forms a passage along which the fork-type stacker crane 9 travels.

On the other hand, at the open end of each chamber 8 of the stacker storage 1, as shown in FIG. 3, an opening/closing door 10 whose upper portion is pivotally supported is rotatably provided. The opening/closing door 10 is designed to close the opening of each chamber by its own weight. In addition, in each chamber 8, a support plate 12 for placing a side-by-side tray 11 is provided on a bottom plate 13.
It is provided so that there is a space between the two.

On the other hand, the fork type stacker crane 9 has the following features:
A fork device 14 is provided so as to be movable up and down.
A door opening device 15 is attached to the fork device 14.

The door opening device 15 includes a pressing member 16 that can freely protrude in the horizontal direction, and a device 17 for placing and removing the parallel plate tray 11. The pressing member 16 pushes the upper end of the opening/closing door 10. As a result, the opening/closing door 10 rotates in the direction of the arrow around the pivot point, and the opening/closing door 10 is located in a horizontal position indicated by the reference numeral 10'.
2 and place the parallel plate tray 11 on the support plate 12, and take out the parallel plate tray 11 placed on the support plate 12 from the chamber 8.

Next, the effect will be explained.

The side-by-side trays 11 conveyed by the conveyor 2 are sent to the loading/unloading station 4 via means not shown. The side-by-side tray 11 sent to the storage side of the loading/unloading station 4 is placed on the fork device 14 of the stacker crane 9 and transported up and down to a position facing a predetermined chamber 8 of the stacker storage 1. .

Then, the door opening device 15 operates, and the pressing member 16
protrudes forward and pushes above the pivot point of the opening/closing door 10 to rotate the opening/closing door 10 in the opening direction about the pivot point, move the fork device 14, and move the parallel plate tray 11 to the support plate. 12.
That is, by pushing the part above the pivot point of the opening/closing door 10, the opening direction of the opening/closing door 10 is set to the stacker crane 9 side as shown by the arrow around the pivot point, thereby freeing up the space in the room 8. Effective use can be achieved.

Next, when the fork device 14 is returned and the pressing member 16 is retracted to the initial position, the opening/closing door 10 rotates by its own weight around the pivot point and closes the opening end.

To take out the side-by-side trays 11 stored in each chamber 8, the fork device 14 is positioned so as to face the open end of the chamber in which the side-by-side trays 11 are stored, and the door opening device 15 is used to open and close the door opening device 15. Open the door 10, move the parallel plate tray 11 placed on the support plate 12 onto the device 17, take it out from the chamber 8, transport the stacker crane 9, and transfer the parallel plate tray 11 placed on the device 17. is sent to the unloading side of the loading/unloading station 5, and then sent to the subsequent process via the conveyor 3.

In addition, in the above embodiment, the opening/closing door is pivoted on the upper end side so that it closes under its own weight.
A hook may be provided on the opening/closing door, and the opening/closing door may be opened and closed by engaging and disengaging this hook, but in this case, since a mechanism such as a hook is attached, the entire device becomes large and the scope of application is limited. is limited.

〔Effect of the invention〕

As described above, according to the present invention, an opening/closing door that closes under its own weight is provided at the opening end of each chamber of the stacker storage, and the portion above the pivot point of this opening/closing door is attached to a fork device for placing articles. Since the door can be opened using a door opening device and items can be stored in each room,
This has the effect that the stacker room can be made smaller, and manual work such as taking out and inserting articles is not required, so that the production process can be automated and the device can be unmanned.
