Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention increases the storage efficiency of a movable rack by enabling the movable rack to be connected using a coupling device and closing the receiving surface by means of a fence truck. At the same time, it relates to a moving shelf device which can enhance safety against earthquakes and the like.

[Conventional technology]

When storing articles, mobile shelves provided with a large number of storage shelves are stacked with the storage surfaces facing each other, and the work shelves are formed by moving the mobile shelves only when the goods are put in and taken out, thereby creating a work passage. Mobile shelving systems are often used to improve space efficiency by efficiently utilizing space.

However, such a movable rack preferably has a large height in order to enhance the storage efficiency of the articles, but on the other hand, the impact due to the movement, the impact due to the earthquake, particularly the collapse due to the impact due to the movement during the earthquake, the dropping of the articles. Even when the ceiling height in the building is large in order to prevent such problems, the ratio between the width and height of the movable shelf is restricted.

Therefore, in order to increase the height of the movable rack, conventionally, there has been proposed one in which the upper part of the movable rack is held by a guide rail that extends in the moving direction of the movable rack.

[Problems to be solved by the invention]

However, the one with the guide rail installed above,
Although the fall can be prevented, the movable shelf is supported up and down, so it is easy to twist during movement, and tilt due to movement cannot be reliably prevented due to play in the holding part.
Therefore, even in a device having such a guide rail, the width-to-height ratio of the movable rack is limited to about 3.

The present invention can increase the height of the movable rack while reducing the fall, tilt, and fall of the stored articles by providing the movable rack with the connecting device so that the movable rack can be integrally moved and the accommodation surface can be closed. , It is an object of the present invention to provide a moving shelf device that can improve the utilization efficiency of the space inside the building.

[Means for solving problems]

The present invention is provided with storage surfaces for arranging storage shelves in multiple stages and multiple rows, arranged side by side with the storage surfaces aligned, movable in a direction orthogonal to the storage surfaces, and separated by moving the storage surfaces apart. A plurality of movable shelves capable of forming working passages between them, a cargo handling vehicle that is capable of passing through the working passages and provided with a transfer tool for delivering and receiving articles to and from the storage shelves, and that can move in the same direction as the movable shelves On the moving rack, there is provided a connecting device for connecting the moving rack by fitting the housing surface with each other and for remotely disconnecting the moving rack when the separating rack is closed. A mobile shelf device provided at a plurality of positions with different heights,
By making it possible to move integrally by the connecting device, the height of the movable rack can be prevented from falling and the stored articles can be prevented from falling, and the height of the space inside the building can be improved.
