Abstract

According to the sewing system of the present embodiment, the sewing machine and the robot arm are fixedly supported at the fixed positions by the base. Therefore, when a target position of the robot arm for the sewing operation is set once, a relative positional relation between the robot arm and the sewing machine is kept by the base even though the sewing system is entirely moved. Therefore, it is not necessary to again perform a setting operation of the target position for the sewing operation, so that the burdens on the teaching operation and the other setting operations are reduced.

First claim

The invention claimed is:

1. A sewing system comprising:
a sewing machine configured to sew a workpiece;
a robot arm which the workpiece is to be detachably held thereto and which is configured to position the held workpiece relative to the sewing machine and to enable any sewing operation;
a unitary base to which the sewing machine and the robot arm are fixedly supported at fixed positions;
a conveyor device comprising a mounting unit to which a clamp jig is to be mounted at a predetermined posture and configured to convey the mounting unit between an operation position at which an operation of mounting the clamp jig to the mounting unit is to be performed and a transfer position at which the clamp jig mounted to the mounting unit is to be transferred to the robot arm, wherein the conveyor device is fixedly supported at a fixed position of the base; and
a display device supported at a fixed position of the base and configured to indicate a moveable range of the robot arm,
wherein the conveyor device is arranged so that the operation position is located at an outside of the moveable range and the transfer position is located at an inside of the moveable range.

2. The sewing system according to claim 1 , wherein the robot arm is configured to hold the workpiece through the clamp jig, and
wherein a coupling structure configured to be detachably mounted from the robot arm-side and to hold the clamp jig at a predetermined posture is provided between the robot arm and the clamp jig.

3. The sewing system according to claim 1 , wherein the conveyor device is configured to transfer the clamp jig to the robot arm at the transfer position, in the same posture and direction as a posture and a direction of the clamp jig mounted to the mounting unit at the operation position.

4. The sewing system according to claim 1 , wherein the base comprises casters.
