The carriage 13 has a large number of support members 1 in a comb shape.
9 are provided, and a V groove 21 for positioning the material W in a predetermined position is provided on the upper surface of each support member 19.

Then, as shown in FIG. 1, the support member 19 is mounted on the carriage 13 at a predetermined position (material transfer position) outside the storage 9.
When the shelves 1 are close to each other, they are inserted between the adjacent support plates 5 and the upper ends of the support plates 5 are formed to protrude upward.

The material W supported by the support member 19
In FIG. 1, a material take-out arm 23 which moves up and down and left and right is used in order to carry the material to, for example, a cutting machine or to put it on the support member 19 from a carrier vehicle (not shown).

Therefore, a gap S between the upper end of the support member 19 and the lower surface of the material W on the support plate 5 of the shelf 1 located at the aforementioned approach position.
Is large enough to allow the material take-out arm 23 to enter and exit.

In order to detect the front, rear, left and right positions of all the materials W supported on the support plate 5 of the shelf 1,
Detection members 25 such as limit switches and proximity switches
