DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. In this specification, the front means the lower side of FIG. 1, the rear means the upper side of FIG. 1, the left means the left side of FIG. 1, and the right means the right side of FIG.

A pair of front and rear rack devices 1 having a large number of article storage shelves 3 vertically and horizontally are provided on the floor so that a predetermined space 7 is provided in the front-rear direction. The rack device 1 includes a large number of front columns 2 arranged side by side at predetermined intervals,
It has a rear strut 2 which is arranged behind these front strut 2 with a predetermined space therebetween, and a large number of article support members 4 provided on these front and rear strut 2. An article storage shelf 3 is configured by a pair of left and right article support members 4 that face each other without intervening. A fork passage gap 5 is provided between the pair of left and right article support members 4 to allow a slide fork 16 to be described later to move in the vertical direction. The article loading / unloading openings 6 of the article storage shelves 3 of the front and rear rack devices 1 face each other.

A pair of upper and lower guide rails 11 whose longitudinal direction is oriented in the left-right direction are provided between the rack devices 1, and a stacker crane 12 is movable left and right along the guide rails 11. The stacker crane 1
Reference numeral 2 denotes a traveling carriage 13, an elevating stand 15 which is vertically movable on a mast 14 standing on the traveling carriage 13 by a known elevating device, and the raising and lowering stand 15 is provided with JP-A-1-1721.
21 and JP-A-59-23762, the slide fork 16 is provided so as to be slidable forward and backward by an advance / retreat mechanism. The slide fork 16
As is well known, the case C protrudes downwardly and is raised / lowered 1
5, the case C can be lifted and retracted to the lift table 15 side to pull the case C into the lift table 15, and the case C can be lowered to the article storage shelf 3 or the like by the reverse operation. ..

A sliding loading platform 18 is provided in a required portion of the front and rear rack devices 1 in place of the article storage shelves 3 by a known left and right guide rail device 21 so as to be horizontally projectable on the back side. The guide rail device 21 includes a rail 22 fixed to the column 2, a rail 23 fixed to the sliding carrier 18, and an intermediate rail 24 interposed between the rail 22 and the rail 23. ing.

A pair of left and right article support members 19 are provided on the sliding platform 18, and a space between the article support members 19 forms a fork insertion space 20 of the slide fork 16.

With the above construction, the sliding bed 18
After the case C is placed on the article supporting member 19 of FIG. 1, the sliding loading platform 18 is horizontally projected to the back side, and the worker M may be swiftly caught by the stacker crane 12 in the small articles in the case C. It can be taken out safely without any.

In the embodiment, since the sliding load carrier 18 is slidably provided on the column 2 via the guide rail device 21, that is, when the sliding load carrier 18 is slidable, Since the surface does not require any construction, the construction is easy and the height position of the sliding carrier 18 can be easily changed according to the construction site. Further, the sliding bed 18 may be operated by a fluid pressure cylinder or the like. Further, two or more sliding bed 18 may be provided in one rack device 1.

[0013]

The present invention has the following effects due to the above-mentioned configuration. After the case is placed on the sliding carrier, the sliding carrier can be horizontally projected to the back side so that the small articles in the case can be quickly and safely taken out by the worker without the risk of being caught by the stacker crane. ..
