Abstract

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.

First claim

What is claimed is:

1. A conveyor device which feeds a thin workpiece from an unwinding roll and conveys the thin workpiece on a conveyance path, the conveyor device comprising:
a pair of first movable holding members configured to detachably hold tip-side end sections at both sides of the thin workpiece fed on the conveyance path and convey the thin workpiece on the conveyance path;
a pair of fixed holding members configured to detachably hold end sections at both sides of a side of the unwinding roll of the thin workpiece fed on the conveyance path;
a cutting device configured to cut the thin workpiece in a width direction thereof between the first movable holding members and the fixed holding members;
a pair of second movable holding members configured to detachably hold end sections at both sides closer to a tip side of the thin workpiece conveyed by the first movable holding members than the end sections at both sides held by the first movable holding member at the tip side thereof and further convey the thin workpiece on the conveyance path;
a first position sensor provided between the unwinding roll and the first movable holding members and configured to detect a position in the width direction of the thin workpiece fed from the unwinding roll;
a first correction mechanism configured to correct a position of the unwinding roll in a direction perpendicular to an unwinding direction based on a detection result of the first position sensor; and
a second correction mechanism configured to correct positions of the fixed holding members holding the thin workpiece in a direction perpendicular to a conveyance direction of the thin workpiece based on the detection result of the first position sensor.

2. The conveyor device according to claim 1 , wherein the first correction mechanism corrects a position of the unwinding roll in a direction perpendicular to the unwinding direction in cooperation with the second correction mechanism when the positions of the fixed holding members holding the thin workpiece in the direction perpendicular to the conveyance direction of the thin workpiece are corrected by the second correction mechanism.
