Materials handling device suited to the transfer and storage of tire carcasses
View Patent ↗Storage or handling device comprising at least one pair of rollers ( 11 ), the axes (rr′) of which are mutually parallel and are arranged a suitable distance (d) apart such that they can support a carcass ( 2 ) of substantially cylindrical shape of a tire that is in the process of being manufactured. The rollers ( 11 ) are mounted on a chassis ( 12 ) and are driven in rotation in the same direction (R) about their respective axes (rr′). One of the rollers ( 11 ) of said pair has a radial profile of sinusoidal overall shape comprising a succession of crests and of troughs, and the other roller of the pair has a cylindrical overall profile.
1. A storage or handling device comprising at least one pair of rollers, the axes of which are mutually parallel and are arranged a suitable distance apart such that they can support a carcass of substantially cylindrical shape of a tire that is in the process of being manufactured, said rollers being mounted on a chassis and driven in rotation in the same direction about their respective axes, wherein one of said rollers of said pair has a radial profile of sinusoidal overall shape comprising a succession of crests and of troughs, and the other roller of said pair has a cylindrical overall profile.
2. The device according to claim 1 , wherein the length between two consecutive crests is between 25 mm and 50 mm.
3. The device according to claim 1 , wherein the amplitude between a crest and a trough is between 5 and 10 mm.
4. The device according to claim 1 , wherein just one of the rollers of said pair is driven in rotation by a motorized drive means and wherein the other roller of said pair is free and revolves about its axis under the effect of the rotation of the carcass.
5. The device according to claim 1 , comprising a plurality of pairs of rollers arranged in such a way that the axes of any two consecutive rollers are mutually parallel and separated by a space, and wherein the rollers are driven with a translational movement in a direction P perpendicular to the axes of the rollers so as to form a conveyor, the direction of travel of which corresponds to the direction P.
6. The device according to claim 5 , wherein the axes of the rollers are substantially coplanar.
