The present disclosure is a conveyor device which feeds a thin workpiece from an unwinding roll and conveys the thin workpiece on a conveyance path. The conveyor device includes first movable holding members, fixed holding members, a cutting device, second movable holding members, a first position sensor, and a first correction mechanism.

Conveyor device

A belt-form body conveyor that conveys a belt-form body includes a plurality of non-contact guide portions over which portions of the belt-form body are wound, and that support the belt-form body in a non-contact manner, a drive unit that moves at least one non-contact guide portion out of the plurality of non-contact guide portions, and a control unit that causes the non-contact guide portion to be moved by the drive unit such that a length of a path in which a first edge in a width direction of the belt-form body travels is different from a length of a path in which a second edge which is opposite to the first edge in the width direction of the belt-form body travels.

Belt-form body conveyor

A belt-form body conveyor that conveys a belt-form body includes a plurality of non-contact guide portions over which portions of the belt-form body are wound, and that support the belt-form body in a non-contact manner, and a drive unit that, when viewed in a direction that is perpendicular to a surface of the belt-form body before the belt-form body is supplied to the plurality of non-contact guide portions, causes at least two non-contact guide portions out of the plurality of non-contact guide portions to rotate in the same direction and by the same angle.

The present disclosure is a tension control device which includes a pressing member configured to press an object in a noncontact manner by spraying a gas onto the object to which tension is applied, an actuator configured to vary a position of the pressing member, a pressure sensor configured to detect pressure of the gas, a gap sensor configured to detect a floating amount of the object from the pressing member, and a control unit configured to control the actuator based on a detected value of the pressure sensor and a detected value of the gap sensor.
