Conventional loaders that carry green tires into tire vulcanizers are installed on the front side of the tire vulcanizer, and when not in operation, they stand by at the position where they grip the green tires, resulting in problems that impede mold replacement. In addition, the plurality of shoes that grip the inner diameter side of the green tire bead portion in the raw tire gripping device of the loader have a structure in which only a part of the shoes is moved forward and backward by a cylinder or the like, and the plurality of shoes are There is a risk that the arrangement may be circular or uneven, or that the expansion force of the shoe may apply large tension to the bead of the raw tire, contributing to a decline in tire quality, as well as the gripping function of certain tire sizes. However, if the tire size is changed, there is a drawback that troublesome reassembly work is required, such as replacing the ring that restricts the expansion of the shoe.

The present invention has the above-described configuration, and by changing and adjusting the pivot position of at least one of the hydraulic cylinders in accordance with the raw tire size, the hydraulic cylinder is actuated with a predetermined stroke. The expansion/contraction operation set position of the plurality of sliders, that is, each shoe, can be extremely easily changed to the optimum state corresponding to the raw tire size, and the expansion force of the shoe is always at a prescribed value by ensuring a prescribed stroke of the fluid pressure cylinder. In addition, sliders with shoes that are slidably disposed in each of the plurality of radial grooves provided in the disk are individually connected to the disk by links, so that the slider is actuated via the disk and the links. Each shoe is always aligned in a circular arrangement, so even if the size of the raw tire changes, it is possible to accurately grip the raw tire with the specified expansion force and in a circular arrangement, which significantly improves raw tire gripping performance and reliability. It has been improved.

Therefore, since the raw tire (a) has various inner diameters called bead diameters, it is necessary to set the gripping position of the shoe C1IJ at the expansion/contraction operation set position in accordance with the bead size of the raw tire. However, in this embodiment, as shown in Fig. 2, the bottle (2) provided in the clevis (22b) of the fluid pressure cylinder @ is selected from one of the plurality of holes (19b) provided in the disc. The fluid pressure cylinder (24) is always operated within a predetermined stroke range by changing and adjusting the pivot position, and the expansion/contraction operation set position of a plurality of sliders @, that is, each shoe QD is generated. It is extremely easy to adjust the length to the optimum condition corresponding to the tire size, and even if the raw tire size changes,
The fluid pressure cylinder (24) is always actuated with a predetermined stroke, and each shoe (Q) moves accurately to expand and contract according to the raw tire size, and each shoe (211 Because the circular arrangement of the tires is always aligned, the green tire (aJ) can always be accurately gripped, and excessive expansion force is not applied to the bead diameter (furthermore, the tire is released smoothly,
Tire gripping performance, release and reliability are significantly improved.
