Description

[Detailed description of the invention] A three-dimensional automated warehouse system in which the bottom surface of box-shaped items containing parts or documents, etc., is slidably carried into and out of three-dimensional shelves using a transporter such as a stacker-type crane. In this article storage device, in order to easily and smoothly carry the box-like stored items into and out of the three-dimensional shelf by the transporter, the bottom surface of the box-like stored item, the support surface of the shelf, and the lifting platform of the transporter are It is desirable that there is little friction between the support surface and the support surface.

However, when a horizontal force such as an earthquake is applied,
If the friction is small, the box-shaped items stored on the shelves will slip and protrude toward the passageway of the conveyor,
Or, there was a sufficient risk of falling from the shelf into the aisle.

In order to prevent this kind of danger, a locking piece is attached to the shelf booth, and a box-shaped stored item is locked to this locking piece, as described in Japanese Utility Model Publication No. 55-92608. Things have always been hot.

In the system described in Japanese Utility Model Application Publication No. 55-92608, a shelf board is stretched across the entire bottom of each shelf booth, and the base end of a plate-shaped locking member is located at the back of this shelf board. The front end of this plate-shaped locking member is bent at a right angle centering on the frontage direction, and further bent downward at the front end so as to be inclined diagonally downward toward the front. .

Since the shelf boards are stretched over the entire surface of the bottom of each shelf booth, material costs are high, resulting in high costs.

In addition, the base end of the plate-shaped locking member is installed in a cantilevered manner at the back of the shelf, and the elastic force of this locking member itself is used to return the plate-shaped locking member upward. , the work of attaching the locking member is troublesome, the plate-shaped locking member tends to bend downward under its own weight, and when a box-shaped article is locked to the bent portion at the tip of the locking member, the tip of the plate-shaped locking member is easily bent downward. When a force is applied to the bent portion in the drawing direction, the tip bent portion deforms in the drawing direction and is likely to come off.

The present invention relates to an improvement in the measurement of box-shaped stored items to prevent them from slipping out, which overcomes these difficulties.A large number of shelf booths are arranged vertically, horizontally, and horizontally, and the box-shaped stored items are moved onto the shelves by a transport machine. In the shelves that are slidably carried in and out of the booth, each shelf booth is configured by a pair of left and right angle-shaped support members arranged on both sides of each shelf booth, and a pair of left and right angle support members in each shelf booth are configured. A locking member is pivotally supported at the frontage end of the horizontal inner edge of the shaped support member so as to be rotatable about a direction perpendicular to the frontage surface, and the locking step portion of the locking member is rotatably supported at the frontage end of the horizontal inner edge of the support member. It is bent upward at a right angle about a direction parallel to the axis, and the upper surface of the locking step is formed to be inclined obliquely downward toward the front, so that the upper surface of the locking step is always positioned upward. It is characterized by a coil spring fitted coaxially with the pivot shaft of the locking member, and its purpose is not only to ensure safety in the event of an earthquake, but also to simplify the operation of the conveyor. The object of the present invention is to provide a device for preventing stored objects from slipping out.

Since the present invention is configured as described above, the elastic force of the coil spring is such that when the box-shaped stored object is stored in a normal position, the upper surface of the locking step is always located upward. , and the lower edge of the frontage surface of the box-shaped storage is engaged with the locking step of the locking member, so even if an external force such as an earthquake acts, the locking member will hold the box-shaped It is extremely safe for the stored items to neither protrude from the shelves nor fall into the aisles.

Further, in the present invention, the box-shaped stored items stored in the shelf booth can be carried out by lifting the front side of the box-shaped stored items in the shelf booth and pulling it out with a conveyor. .

Further, in the present invention, with the bottom surface of the box-shaped stored item set at a height slightly above the supporting surface of the shelf booth, the box-shaped stored item is moved in the depth direction of the shelf booth by a conveyor. If you move it to
The upper surface of the locking step of the locking member is pressed by the bottom surface of the box-shaped storage, and rotates around a direction perpendicular to the frontage surface against the elastic force of the coil spring, and the box Stored objects such as the above are easily carried into the shelf booth.

As described above, according to the present invention, the loading of the stored items can be carried out very simply in the same way as with ordinary shelves.

In addition, in this invention, a pair of angle-shaped support members are placed on both sides of each shelf booth, so there is no need to extend shelf boards over the entire bottom of each shelf booth, reducing material costs. Cost reduction can be achieved.

Furthermore, in the present invention, a locking member is pivotally supported at the horizontal inner edge frontage end of the pair of left and right angle-shaped support members in each shelf booth so as to be rotatable about a direction perpendicular to the frontage surface. Even if a pulling force or pushing force in a direction perpendicular to the plane is applied to the locking member, no bending load is applied to the pivot shaft of the locking member, and a force along the longitudinal direction is applied to the pivot shaft of the locking member.
The pivot shaft can reliably bear this force without causing bending deformation.

Moreover, in the present invention, since this pivot portion is located at the frontage end, this installation work is extremely easy.

Furthermore, in the present invention, the locking step portion of the locking member is bent upward at a right angle centering on a direction parallel to the pivot axis of the locking member, so that the locking step portion of the locking member When a pull-out force or push-in force is applied in a direction parallel to the pivot axis, the locking member has high rigidity in this direction and is unlikely to deform, and the box-shaped stored item will not come off from this locking step. It is possible to maintain the locked state reliably and firmly.
