  "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.",
  "claims": [
    "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."

  "description_excerpt": "The present invention relates to a sewing system including a robot arm.\n\nA sewing system configured to supply a workpiece to a sewing machine and to move a cloth so as to drop a needle to a predetermined needle drop position with holding the workpiece has been suggested (for example, refer to Japanese Patent Application Publication No. S61-265169A). The sewing system includes a robot arm having a suction hand configured to suck the workpiece and mounted to a tip end portion of the robot arm.\n\nIn the sewing system having the robot arm, it is necessary to perform an operation referred to as so-called teaching operation for teaching a controller of the robot arm respective positions such as a receiving position of the workpiece, a sewing position of the sewing machine, a stock position of the workpiece for which a sewing operation has been completed, and the like.\n\nHowever, according to the sewing system, since the sewing machine and the robot arm are independently provided, a positional deviation occurs therebetween when the sewing system is moved or rearranged, so that the teaching operation should be again performed.\n\nThe present invention is to provide a sewing system capable of reducing a troublesome teaching operation, and has any one feature of following configurations (1) to (6).\n\nAccording to the sewing system of the present invention, the sewing machine and the robot arm are fixedly supported at the fixed positions by the base.",
