Tire vulcanizer-unloading device and tire vulcanizer

1. An unloading device of a tire vulcanizer in which a vulcanized tire vulcanized by a vulcanizer main body is taken out of a mold installed in the vulcanizer main body and is transported to a cooling position at which the vulcanized tire is cooled, and the vulcanized tire cooled at the cooling position is transported to a discharge position for transfer to an exporting device for discharging the vulcanized tire, the unloading device comprising:

a guide frame extending vertically;

a base extending horizontally which is mounted to the guide frame;

a rotational movement section including a rack gear which is mounted to the base and a pinion gear provided to mesh with teeth provided on a lateral side of the rack gear and rotate about a vertical axis;

a support section mounted on the pinion gear and configured to support the vulcanized tire; and

a linear movement section which is mounted to the base, the linear movement section being configured to linearly move the rack gear which is provided above the base in a direction away from or toward the guide frame,

wherein the teeth provided on the rack gear are formed in a predetermined range such that meshing of the rack gear and the pinion gear is released when the vulcanized tire supported by the support section is rotated and positioned at the cooling position,

wherein the linear movement section includes a cylinder configured to linearly move the support section with the pinion gear in a state that the meshing of the rack gear and the pinion gear is released at the cooling position, and

wherein the rotational movement section is configured to rotate the support section in a plan view by rotation of the pinion gear when the linear movement section linearly moves the rack gear.

2. The unloading device of a tire vulcanizer according to claim 1 , wherein the linear movement section is able to move along a direction toward the discharge position from the vulcanizer main body.

3. The unloading device of a tire vulcanizer according to claim 2 , wherein the rotational movement section rotates the vulcanized tire from a position where the vulcanized tire is taken out of the mold, to the cooling position, and

the linear movement section linearly moves the vulcanized tire from the cooling position to the discharge position.

4. The unloading device of a tire vulcanizer according to claim 3 , further comprising:

an elevating section which vertically elevates the linear movement section.

5. The unloading device of a tire vulcanizer according to claim 4 , further comprising:

a detection unit which detects a height position of the linear movement section; and

a controller which controls the elevating section on the basis of the height position detected by the detection unit.

6. The unloading device of a tire vulcanizer according to claim 1 , wherein the support section is rotated by the forward and rearward movements of the rack gear.

7. A tire vulcanizer comprising:

the unloading device according to claim 1 ;

the vulcanizer main body which performs vulcanization on a green tire which is not vulcanized;

a post-cure inflator which cools the vulcanized tire vulcanized by the vulcanizer main body, at the cooling position; and

an exporting device for discharging the vulcanized tire cooled at the cooling position.

8. The tire vulcanizer according to claim 7 , wherein the post-cure inflator is fixed to the vulcanizer main body.
