Description

DETAILED DESCRIPTION OF THE INVENTION For example, as shown in FIG. 1, there is a three-dimensional automatic machine in which parts or documents, etc. are placed in a box a and transported into and out of a shelf c of a three-dimensional shelf b using a stacker-type conveyor d. In the warehouse-type article storage device, in order to easily and smoothly transport the boxes A into and out of the shelf c of the three-dimensional shelf b by the transport machine d, the support surface e of the shelf c is horizontal; It is also desirable that there be little friction between the bottom surface of the box a and the support surface e of the shelf booth c and the support surface g of the lifting platform f of the conveyor d.

However, when a horizontal force such as an earthquake is applied, if the shelf support surface e is horizontal and the friction is small, the boxes a stored in the shelf booth c will slip and protrude toward the path h of the transport machine d. , or there was a sufficient risk of falling from the shelf d into the passage h.

In addition, in order to detachably engage the engaging claw j on the loading platform f with the locking piece i provided at the end of the box a, conventionally, the container reloading method described in Publication of Utility Model Publication No. 55-38888 has been used. Although a device existed, this device required a mechanism for raising and lowering the engaging claw j and a mechanism for moving the engaging claw j back and forth, and had a complicated structure.

The present invention relates to an improvement of an article storage device that overcomes these difficulties, and in which a large number of shelf booths are arranged vertically and horizontally, and container support members are arranged on shelves that are inclined downward from the shelf opening toward the back. , a container storage device in which containers can be carried in and out separately using a stacker-type conveyor, in which a locking piece is provided at the end of the container, a loading platform that can be raised and lowered is provided on the stacker-type conveyor, and a shelf opening is provided. The loading platform is provided with a tilting means for tilting the tilting frame around a loading platform center axis that is parallel to the horizontal line along the loading platform and located in the longitudinal center of the loading platform, and the tilting frame is movable along the longitudinal direction of the tilting frame. is provided with an engaging means, and by the operation of the tilting means, the tilting frame is tilted from a state where it is tilted at an inclination angle equal to or higher than the inclination angle of the shelf booth to the inclination angle of the shelf booth, so that the engaging means is moved to the container. When the inclined frame is tilted beyond the inclination angle of the shelf booth from the state in which the engaging means is engaged with the engaging piece, the engaging means is engaged with the container. It is characterized by being configured to be detached from the stopper,
The purpose is to provide a container storage device that can be stored extremely safely even in the event of an earthquake, and is compact and inexpensive.

As described above, in the present invention, a large number of shelf booths are arranged in the vertical and horizontal directions, and containers are individually carried out using a stacker-type conveyor onto a shelf where the container support members are inclined downward from the shelf frontage towards the back. Since the shelves are configured so that the containers can be placed in the storage booth, when the containers are supported by the tilted container support members of the shelves and stored in the storage booth, the containers stored in the storage booth will not move in the depth direction due to their own weight. A force that constantly moves the container in the depth direction along the inclined container support member acts, and as a result, even if a horizontal force is applied to the container due to an earthquake, the container will not remain in the storage booth. It is held firmly and stably, and the container does not protrude from the storage booth or fall into the aisle, making it extremely safe.

Further, in the present invention, in the container storage device, the stacker-type conveyor is provided with a loading platform that can move up and down, and the frame is tilted around a central axis of the loading platform that is parallel to the horizontal line along the shelf frontage and located at the center in the longitudinal direction of the loading platform. The loading platform is provided with a tilting means for tilting the container, and the tilting frame is provided with an engaging means capable of moving along the longitudinal direction of the tilting frame and detachably engaging with a locking piece on the container. While moving the loading platform to a required shelf booth, the engaging means is driven to a position where it can engage with the locking piece of the container stored in this shelf booth, and then the tilting means is driven to move the tilting frame. By tilting the container, the engaging means can be engaged with and disengaged from the locking piece of the container, and by moving the engaging means, the container can be carried in and out of the shelf booth, and as a result,
There is no need for a means for raising and lowering the engaging means, and the structure is simplified.

Furthermore, since the engaging means can be engaged and disengaged from the locking piece of the container by tilting the tilting means, the mechanism is simple and costs can be reduced.

The present invention will be described below with reference to the embodiments shown in FIGS. 2 to 13.
