Abstract
A conveyance device for glass sheets advancing them one after the other, includes at least one roller including a glass sheet conveyance area, the device including actuators located on either side of the conveyance area capable of bending the roller within its elastic deformation domain while leaving it able to be driven in rotation around fixed centers of its sections, wherein the roller includes a shaft and a plurality of bending rings into which the shaft is inserted.
Claims28
A conveyance device for glass sheets advancing them one after the other, comprising:
- at least one roller comprising a glass sheet conveyance area,
- actuators located on either side of the conveyance area capable of bending each of the at least one roller within its elastic deformation domain while leaving it able to be driven in rotation around a central axis thereof,
- wherein said at least one roller comprises a shaft and a plurality of bending rings into which said shaft is inserted, the rings being tightly mounted on said shaft and the rings being arranged on the shaft to form a substantially continuous profile for engaging the glass;
- wherein each bending ring comprises a central opening having an inner face, said inner face comprising a chamfer on each edge between the inner face and a lateral face.
A conveyance device for glass sheets advancing them one after the other, comprising:
- at least one roller comprising a glass sheet conveyance area,
- actuators located on either side of the conveyance area capable of bending each of the at least one roller within its elastic deformation domain while leaving it able to be driven in rotation around a central axis thereof,
- wherein said at least one roller comprises a shaft and a plurality of bending rings into which said shaft is inserted, the rings being tightly mounted on said shaft and the rings being arranged on the shaft to form a substantially continuous profile for engaging the glass;
- wherein the bending rings each comprises a chamfer on each edge between a radially facing surface and a lateral face;
- wherein the chamfers have a width between 0.1 and 0.5 mm with an angle of between 30 and 60°.
