Tire transport method, tire transport and fastening apparatus, and tire inspection system
Provided is a tire transport method for a tire inspection system in which a tire transported from the upstream side is fastened by an upper rim and a lower rim, and a measurement is performed, wherein the method includes transport stem in which a transport mechanism having a pair of transport units split in the width direction transports the tire to a fastening position for fastening, and a parting step in which the pair of transport units is parted in the width direction, such that it is possible for the lower rim to pass between the pair of transport units.
1. A tire transport method in a tire inspection system for performing measurement with a tire transported from an upstream side fastened by an upper rim and a lower rim, the method comprising:
a transport step of transporting the tire to a fastening position for fastening the tire by a transport mechanism having a pair of transport units divided in a width direction, while a distance between the pair of transport units is dimensioned such that the lower rim cannot pass into a space between the pair of transport units in a vertical direction; and
a spacing-apart step of making the pair of transport units be spaced apart from each other in the width direction such that the lower rim can pass between the pair of transport units, if the tire is transported to the fastening position by the pair of transport units.
2. The transport method according to claim 1 , further comprising:
a holding step of holding the tire disposed on the pair of transport units at the fastening position,
wherein the spacing-apart step is performed in a state where the tire is held in the holding step.
3. The transport method according to claim 2 , wherein in the holding step, the tire disposed on the pair of transport units is held by the upper rim.
4. A tire inspection system comprising:
a measuring device for measuring characteristics of the tire transported by the tire transport method according to claim 1 .
5. A tire transport and fastening device for transporting a tire to a fastening position set in advance and pinching and fastening the tire by an upper rim and a lower rim at the fastening position, the device comprising:
a pair of transport units divided in a width direction, for transporting the tire;
a slide mechanism for making the pair of transport units approach each other and be spaced apart from each other in the width direction; and
a control unit for controlling approach and spacing-apart of the pair of transport units by the slide mechanism,
wherein the control unit makes the pair of transport units be spaced apart from each other by the slide mechanism such that the lower rim can pass between the pair of transport units, if the tire is transported to the fastening position by the pair of transport units, while a distance between the pair of transport units is dimensioned such that the lower rim cannot pass into a space between the pair of transport units in a vertical direction when the tire is transported to the fastening position.
6. The tire transport and fastening device according to claim 5 , further comprising:
a holding mechanism for holding the tire transported to the fastening position, thereby restricting movement of the tire, when the pair of transport units is spaced apart from each other by the slide mechanism.
7. The tire transport and fastening device according to claim 6 , wherein the holding mechanism holds the tire by the upper rim.
8. A tire inspection system comprising: the transport and fastening device according to claim 5 ; and
a measuring device for measuring characteristics of the tire fastened by the upper rim and the lower rim.
