Support and rotation device for the visual inspection of a tire and associated method
First Claim
1. An inspection device for holding and turning a tire having a tread and first and second lateral beads, the device comprising:
- a centering device structured to enable the first lateral bead of the tire to be centered;
a locking device structured to lock the first lateral bead in a centered position;
a rotation driver arranged to turn the tire about an axis of the tire; and
at least one centering gripper module arranged to interact with the second lateral bead of the tire, each centering gripper module including;
an internal spacing roller arranged to be able to press axially against an internal face of the second lateral bead,at least one external holding roller arranged to be able to bear axially against an external face of the second lateral bead opposite the internal face, andat least one centering roller arranged to be able to bear radially against the second lateral bead,wherein each centering roller extends along an axis oriented axially, parallel to the axis of the tire, andwherein the internal spacing roller and each external holding roller each extend along an axis oriented radially, perpendicular to the axis of the tire.

Abstract
An inspection device for holding and turning a tire includes a centering structure which centers a first bead of the tire, a locking structure which locks the first bead in a centered position, a rotational driver which turns the tire about a tire axis, and at least one centering gripper module which interacts with a second bead of the tire. Each centering gripper module is provided with an internal spacing roller, an external holding roller, and a centering roller. The internal spacing roller is able to press axially against an internal face of the second bead. The external holding roller is able to bear axially against an external face of the second bead opposite the internal face. The centering roller is able to bear radially against the second bead and extends substantially axially. The internal spacing roller and the external holding roller extend substantially radially.

15. A method for inspecting a tire using an inspection device for holding and turning a tire that has a tread and first and second lateral beads, wherein the inspection device includes:
- a centering device, a locking device, a rotation driver, and at least one centering gripper module, wherein each centering gripper module includes;
an internal spacing roller, at least one external holding roller, and at least one centering roller, wherein each centering roller extends along an axis oriented axially, parallel to the axis of the tire, and wherein the internal spacing roller and each external holding roller each extend along an axis oriented radially, perpendicular to the axis of the tire, the method comprising;centering the first lateral bead of the tire on the centering device; locking the tire on the centering device using the locking device to lock the first lateral bead in a centered position; for each centering gripper module, positioning the internal spacing roller relative to the tire by causing a relative axial movement between the tire and the internal spacing roller, such that the internal spacing roller presses against an internal face of the second lateral bead, and such that the internal spacing roller is positioned axially at a different height from a height of the internal face of the second lateral bead while being situated in an interior space of the tire; deploying each centering gripper module radially to bring the at least one centering roller to a dimension smaller than a seat of the tire; actuating the rotation driver to turn the tire; for each centering gripper module, causing a relative axial movement between the tire and the internal spacing roller in order to pinch the second lateral bead axially between the internal spacing roller and the at least one external holding rollers; deploying each centering gripper module radially to bring the at least one centering roller radially to bear against the second lateral bead at a dimension corresponding to the seat of the tire, and capturing internal and external images of angular regions of internal and external surfaces of the tire using an image capturing device.
- a centering device, a locking device, a rotation driver, and at least one centering gripper module, wherein each centering gripper module includes;
