Abstract
At the time of transfer of a strip-shaped rubber member (15) onto a belt conveyor (12) by a transfer unit, support members (61), each of which is provided on one width-direction side of a corresponding belt (51) and is projectable from a conveying surface of the belt (51), are lifted by a lifting/lowering unit (71) to project from the conveying surface of the belts (51), so that the strip-shaped rubber member (15) is raised from the conveying surface of the belts (51). Therefore, the strip-shaped rubber member (15) is not in sliding contact with the conveying surface of the belts (51) at the time of transfer. As a result, a situation whereby the belts (51) are dragged by the strip-shaped rubber member (15) so that one width-direction edge portion thereof is turned up can be prevented.
Claims6
A method for transfer cutting a strip-shaped rubber member, comprising the steps of:
- transferring the strip-shaped rubber member onto a belt conveyor by a transfer unit moving the strip-shaped rubber member in a longitudinal direction of the strip-shaped rubber member while holding a tip portion thereof, the strip-shaped rubber member being at an inclination with respect to the belt conveyor, the belt conveyor including a belt running in a longitudinal direction of the belt conveyor;
- cutting off a sheet piece from the strip-shaped rubber member by a cutting unit cutting the strip-shaped rubber member on the belt conveyor in the longitudinal direction of the belt conveyor at one width-direction side of the belt conveyor, yielding a cut-off sheet piece;
- and
- transporting, by the belt conveyor, the cut-off sheet piece in the longitudinal direction of the belt conveyor, wherein
- at a time of transfer of the strip-shaped rubber member by the transfer unit, a support member is lifted by a lifting/lowering unit to project from a conveying surface of the belt, the support member being provided at one width-direction side of the belt and being projectable from the conveying surface of the belt, so that the strip-shaped rubber member is raised from the conveying surface of the belt.
A device for transfer cutting a strip-shaped rubber member, comprising:
- a belt conveyor including a belt running in a longitudinal direction of the belt conveyor;
- a transfer unit configured to transfer the strip-shaped rubber member onto the belt conveyor by moving the strip-shaped rubber member in a longitudinal direction of the strip-shaped rubber member while holding a tip portion thereof, the strip-shaped rubber member being at an inclination with respect to the belt conveyor;
- and
- a cutting unit configured to cut off a sheet piece from the strip-shaped rubber member by cutting the strip-shaped rubber member on the belt conveyor in the longitudinal direction of the belt conveyor at one width-direction side of the belt conveyor, yielding a cut-off sheet piece, wherein
- the belt conveyor transports the cut-off sheet piece in the longitudinal direction of the belt conveyor,
- a support member, at one width-direction side of the belt, projectable from a conveying surface of the belt, is provided along with a lifting/lowering unit configured to lift and lower the support member, and
- at a time of transfer of the strip-shaped rubber member by the transfer unit, the support member is lifted by the lifting/lowering unit to project from the conveying surface of the belt, so that the strip-shaped rubber member is raised from the conveying surface of the belt.
