Abstract

A tire mounting apparatus is constructed from a first working mechanism and a second working mechanism that are separate from each other. The first working mechanism is provided with a tire holding device for holding a tire and with a temporary tightening device for temporarily tightening nuts onto hub bolts to which the tire is mounted. The second working mechanism is provided with a final tightening device means for finally tightening the temporarily tightened nuts. The final tightening device includes two nut runners and an interval adjuster for adjusting an interval between the two nut runners.

First claim

The invention claimed is:

1. A tire mounting apparatus for automatically mounting a tire onto hub bolts of a motor vehicle, comprising:
a first working mechanism including tire gripping means for gripping the tire, and temporary tightening means for temporarily tightening nuts on the hub bolts on which the tire has been placed;
a second working mechanism disposed in association with a first mounting region on a front wheel side of the motor vehicle, and including first full tightening means for fully tightening the nuts that have been temporarily tightened, after the tire is set in the first mounting region by the first working mechanism; and
a third working mechanism disposed in association with a second mounting region on a rear wheel side of the motor vehicle, and including second full tightening means for fully tightening the nuts that have been temporarily tightened, after the tire is set in the second mounting region by the first working mechanism,
wherein each of the first working mechanism, the second working mechanism, and the third working mechanism independently includes a body and an arm,
the first working mechanism, the second working mechanism, and the third working mechanism are positioned on a same side of the motor vehicle when viewed along a direction in which the motor vehicle is conveyed, and
the first working mechanism is disposed between the second working mechanism and the third working mechanism.

2. The tire mounting apparatus according to claim 1 , wherein the second working mechanism includes a first detection sensor for detecting positions of the hub bolts in the first mounting region; and
the third working mechanism includes a second detection sensor for detecting positions of the hub bolts in the second mounting region.

3. The tire mounting apparatus according to claim 2 , further comprising:
a third detection sensor for detecting bolt holes of the tire, which is disposed in a tire supply; and
a control mechanism for processing position information from the first through third detection sensors, and controlling operation of the first working mechanism.

4. The tire mounting apparatus according to claim 1 , wherein the temporary tightening means comprises:
a plurality of detachable nut runners; and
a single rotational drive source for rotating the nut runners in unison with each other.

5. The tire mounting apparatus according to claim 1 , wherein each of the first full tightening means and the second full tightening means comprises:
two nut runners; and
an interval adjuster for adjusting an interval between the two nut runners.
