Abstract

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.

First claim

What is claimed is:

1. A belt-form body conveyor that conveys a belt-form body comprising:
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 causes at least two non-contact guide portions out of the plurality of non-contact guide portions to rotate
wherein the plurality of non-contact guide portions include:
an upstream-side turn bar that, of the plurality of non-contact guide portions, is disposed further on an upstream side in a travel direction of the belt-form body, and alters the travel direction of the belt-form body;
a downstream-side turn bar that, of the plurality of non-contact guide portions, is disposed furthest on a downstream side in the travel direction of the belt-form body, and causes a position of the belt-form body in a thickness direction of the belt-form body to match the position of the belt-form body before the belt-form body is supplied to the upstream-side turn bar; and
an inverter turn bar that reverses the travel direction of the belt-form body, which has been altered by the upstream-side turn bar, towards the downstream-side turn bar, and
wherein the upstream-side turn bar, the downstream-side turn bar and the inverter turn bar are rotated in the same direction and by the same angle 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.

2. The belt-form body conveyor according to claim 1 , further comprising:
an upstream-side edge sensor that is disposed on the upstream side of the upstream-side turn bar, and detects an edge position of the belt-form body;
a downstream-side edge sensor that is disposed on the downstream side of the downstream-side turn bar, and detects an edge position of the belt-form body; and
a control unit that controls the drive unit based on at least one of a detection result from the upstream-side edge sensor and a detection result from the downstream-side edge sensor.

3. The belt-form body conveyor according to claim 2 ,
wherein the drive unit includes:
an actuator; and
a link mechanism that transmits motive force generated by the actuator to the at least two non-contact guide portions.

4. The belt-form body conveyor according to claim 1 ,
wherein the drive unit includes:
an actuator; and
a link mechanism that transmits motive force generated by the actuator to the at least two non-contact guide portions.
