  Among these, the transport rails 21 and 41 with rollers of the transport shelf 2 and the transport shelf 4 are arranged in a direction in which the plurality of transport rails 21 and 41 with rollers (in this embodiment) are transported in the transport direction of the object W. A predetermined inclination angle (which differs depending on the object to be conveyed W, but usually 2 ° so that the object to be conveyed W moved in parallel and automatically moves without the need for power by the action of its weight. It is arranged so as to be inclined at about ~ 20 °.

On the other hand, the transport rail 31 with rollers of the switching shelf 3 is placed on the upper surface of the shelf plate 30 of the switching shelf 3 made of a substantially rectangular flat plate so as to form the transport direction of the upstream transport shelf 2 and the direction substantially perpendicular thereto. The conveying direction rails 31a, 31b arranged so as to be substantially L-shaped parallel to the outer edges 30a, 30b of the plate 30 and the conveying direction of the conveying shelf 2 on the upstream side have a predetermined angle in plan view with respect to the shelf 30 A linear inclined rail 31c disposed in the vicinity of the center position is used.
In this embodiment, the linear inclined rail 31c is closer to the inner edge side 30c and the center position than the center position of the shelf board 30 at an angle of approximately 45 ° in plan view with respect to the transport direction of the upstream transport shelf 2. Two inclined rails respectively arranged on the outer edge side, and an angle of about 30 ° and about 60 ° between these two inclined rails when viewed in plan with the conveying direction of the upstream conveying shelf 2. The two inclined rails are configured.
In this case, the transport rails 31 with rollers are fixed to the shelf plate 30 of the switching shelf 3 by appropriate fixing means such as an adhesive tape and an adhesive in addition to the screws 31d.
The number and the angle at which the inclined rails 31c are arranged are not limited to those of the present embodiment, and can be arbitrarily set. However, the angle at which the inclined rails 31c are arranged is on the upstream side of the transport shelf 2 side. In the case of the one arranged on the side of the conveyance shelf 4 on the downstream side in the direction of the conveyance direction of the conveyance shelf 2 on the upstream side. These are arranged at an angle of approximately 45 ° to 75 ° in plan view with respect to the transport direction of the side transport shelf 2.
As described above, by arranging the roller-equipped transport rail 31 of the switching shelf 3, the transported object W is smoothly and accurately received in the switching shelf 3 without rotating or moving diagonally. It can be sent out from the switching shelf 3.

Further, in particular, the roller-equipped transport rail 31 disposed on the switching shelf 3 has a roller 311 that is rotatably attached to the transport rail 31 and has no corner at the end, for example, in a substantially barrel shape as shown in FIG. In addition to the formed one, it is preferable to use a substantially cylindrical shape with a chamfered end or a rounded end.
Thus, the conveyed object W is not caught at the end of the roller 311, and the conveyed object is accurately and smoothly received in the switching shelf 3 without rotating or moving obliquely. Can be sent out from.

Further, the shelf 30 of the switching shelf 3 is swingably supported via a rotatable support shaft 32, and the shelf 30 of the switching shelf 3 in the receiving posture and the sending posture is respectively inclined at a predetermined inclination.
