Embodiment Construction

[0023] figure 1 with figure 2 The device in shows the main components forming the device according to the preferred embodiment of the invention.

[0024] In this illustration, a tire P with axis XX' is mounted on a centering device 2 . This centering device comprises a rim 20 shaped to accommodate the level of a seat 25 for receiving the first bead B1 of the tire P.

[0025] Distributed around the circumference of the rim 20 and pivoting around the pin 222 are a plurality of hooks 21 which hold the first bead B1 on the seat 25 around its entire circumference and in position. The rim 20 serves as a reference plate, itself mounted on a support ring 27 with axis XX' and connected by bearings to a frame (not shown) so that said ring 27 can pass through a motorized pinion (not shown) While rotating about the axis XX′, the motorized pinion meshes with a circular toothed rack 26 mounted on the radially outer periphery of the ring 27 . The axis of the rim is geometrically fixed ...

Abstract

A for inspecting the internal surface located between a first and a second bead of a tire (P), comprising means for acquiring the image of the internal surface (1) of the tire, and centering means that are able to lock the first bead around its entire circumference on a reference plate, and to set the tire into relative rotation about its axis XX' with respect to said image acquisition means. This device comprises means for opening and for holding the second bead, said means comprising two internal holding rollers (32, 32) which have a generally radial axis, and at least one external holding roller (33) which has a generally radial axis, is disposed substantially in the middle of the angular sector formed by the two internal holding rollers (31, 32) and is able to come into abutment against the external part of said second bead, the internal (31, 32) and external (33) holding rollers being mounted so as to rotate as one about the axis XX' of said image acquisition means (1).

Description

technical field [0001] The present invention relates to the field of tire manufacture, and more particularly to the field of visual inspection of tires during or at the end of the production process. Background technique [0002] Tire visual inspection is very common in the tire industry and still very frequently relies on the skill of the operator responsible for detecting any visible defects on the tire surface. For this reason, a large number of auxiliary devices have been developed for the treatment and manufacture of particularly hard-to-reach visible areas such as the inner part of the tyre. [0003] As an example, as described by publication US 4 160 537, the function of these devices is to hold the beads of the tire in an open or spaced position and to set the tire into rotation. [0004] As the processing power of computing devices increases, manufacturers now foresee the possibility of automating these inspection tasks. To this end, lighting and digital imaging d...
