Abstract
In a tire removal processing, a clamping step and a tire removing step are executed. In the clamping step, a tire is clamped by an upper support and a lower support by bringing the lower support into contact with a lower side wall of the tire in a state where a lower rim is fitted in the tire and the upper support is in contact with an upper side wall of the tire. In the tire removing step, the tire is detached from the lower rim by relatively moving the lower rim vertically downward with respect to a lower support while the clamping step is maintained.
Claims13
A tire holding device comprising:
- an upper rim which is fitted in an upper bead portion of a tire that is in a state where both side walls thereof face a vertical direction;
- a lower rim which is disposed below the upper rim and fitted in a lower bead portion of the tire to hold the tire along with the upper rim;
- an upper support capable of coming into contact with an upper side wall of the tire;
- a lower support which comes into contact with a lower side wall of the tire to support the tire;
- a lower support moving mechanism which relatively moves the lower support in the vertical direction with respective to the lower rim;
- and
- a controller which controls an operation of the lower support moving mechanism,
- wherein the controller executes
- a clamping step of clamping the tire by the lower support and the upper support by bringing the lower support into contact with the lower side wall of the tire in a state where the upper rim is separated from the upper bead portion of the tire, the lower rim is fitted in the lower bead portion of the tire, and the upper support is in contact with the upper side wall of the tire, and
- a tire removing step of detaching the tire from the lower rim by relatively moving the lower rim vertically downward with respect to the lower support by driving the lower support moving mechanism while maintaining a state where the tire is clamped by the lower support and the upper support.
