- the shelf 82 is formed by forming a circular opening 88 for supporting the green sulfur tire T in a flat plate and a notch 86 through which a handle 92 of a fork 90 described later passes.
- the fork 90 includes a disk-shaped mounting portion 94 having a smaller diameter than the opening 88, and a handle portion 92 extending from the mounting portion 94.
- the fork 90 is moved below the shelf 82, and the downward force is applied to the fork 90 while supporting the unvulcanized tire T with the fork 90.

For this reason, when stored in the shelf 82, there was a problem that the bead portion TB was deformed by the weight of the unvulcanized tire, and the quality of the unvulcanized tire could not be maintained.
- the mounting portion 94 has a disk shape, and when the unvulcanized tire T mounted on the shelf 82 is lifted by the fork 90, the mounting portion 94 becomes a bead. The above problem was exacerbated because the unvulcanized tire T was supported by contacting the inner end of the part TB!
- the uncured tire T is supported by the opening edge 88E of the opening 88 of the shelf 82, the applicable range for the size of the uncured tire is narrow. For this reason, it is necessary to provide a shelf having an opening corresponding to each size. For example, as shown in FIG. 13, when a large-diameter unvulcanized tire TL is held in a shelf 82 having an opening 88 suitable for a medium-diameter unvulcanized tire, the opening edge of the shelf 82 is opened. The 88E abuts against the inside end of the bead TLB of the large diameter uncured tire TL, i.e., a part that is more easily deformed than when a medium diameter uncured tire is held. You.
- both the shelf with openings formed to accommodate large diameter unvulcanized tires and the shelf with openings formed to accommodate medium diameter unvulcanized tires are used in an unvulcanized tire automatic device. It must be set up. For this reason, there has been a problem that the size of the unvulcanized tire automatic warehouse increases and the equipment cost increases.
- Patent Document 2 discloses a pallet-less type automatic warehouse 100 for tires (see FIG. 14) capable of increasing the storage efficiency, that is, reducing the size. This is an example of reducing the distance between the top and the bottom of the tire when the storage areas are formed in a row in the vertical direction (vertical direction), and the above problem is not solved.
