Abstract
A sewing device that, when interposing a workpiece-to-be-sewn between a post head and a pressing mechanism and sewing same by penetrating a machine needle therethrough, shapes the workpiece-to-be-sewn in a prescribed shape and sews same, by seating the workpiece-to-be-sewn in a workpiece holding jig having a plurality of seats arranged along a sewing line for the workpiece-to-be-sewn.
Claims7
A sewing device for performing sewing along a certain sewing line on a workpiece-to-be-sewn in a state of the workpiece-to-be-sewn having been shaped in a certain shape, the sewing device comprising:
- a sewing mechanism including:
- a sewing machine needle configured to, by moving in a reciprocating manner, penetrate through or withdraw from the workpiece-to-be-sewn;
- a post bed that faces the sewing machine needle across the workpiece-to-be-sewn;
- and a pressing mechanism configured to press the workpiece-to-be-sewn against the post bed from a side of the sewing machine needle;
- a drive mechanism configured to move the sewing mechanism;
- and
- a workpiece holding jig configured to hold the workpiece-to-be-sewn, wherein
- the workpiece holding jig includes:
- a plurality of seating portions disposed in a moving direction of the sewing mechanism, each of the seating portions being configured to hold the workpiece-to-be-sewn shaped in a certain shape by the workpiece-to-be-sewn being seated on a seating surface of a certain shape;
- and
- a retraction mechanism configured to, according to a position of the sewing mechanism, retract at least one of the seating portions from the workpiece-to-be-sewn in such a manner that interference between the sewing mechanism and the seating portion is avoided.
A workpiece holding jig used in a sewing device that includes a sewing mechanism and a drive mechanism configured to move the sewing mechanism, the sewing mechanism including:
- a sewing machine needle configured to, by moving in a reciprocating manner, penetrate through or withdraw from a workpiece-to-be-sewn;
- a post bed that faces the sewing machine needle across the workpiece-to-be-sewn;
- and a pressing mechanism configured to press the workpiece-to-be-sewn against the post bed from a side of the sewing machine needle,
- the workpiece holding jig comprising:
- a plurality of seating portions disposed in a moving direction of the sewing mechanism, each of the seating portions being configured to hold the workpiece-to-be-sewn maintained in a certain shape by the workpiece-to-be-sewn being seated on a seating surface of a certain shape;
- and
- a retraction mechanism configured to, according to a position of the sewing mechanism, retract at least one of the seating portions from the workpiece-to-be-sewn in such a manner that interference between the sewing mechanism and the seating portion is avoided.
A sewing method for performing sewing along a certain sewing line on a workpiece-to-be-sewn in a state of the workpiece-to-be-sewn having been shaped in a certain shape, the sewing being performed using a sewing mechanism including:
- a sewing machine needle configured to, by moving in a reciprocating manner, penetrate through or withdraw from the workpiece-to-be-sewn;
- a post bed that faces the sewing machine needle across the workpiece-to-be-sewn;
- and a pressing mechanism configured to press the workpiece-to-be-sewn against the post bed from a side of the sewing machine needle,
- the sewing method comprising:
- a step of shaping the workpiece-to-be-sewn in a certain shape by the workpiece-to-be-sewn being seated on a plurality of seating portions disposed along a sewing line of the workpiece-to-be-sewn;
- a step of forming a retraction region where both surfaces of the workpiece-to-be-sewn have been set adrift by retracting some of the seating portions;
- and
- a step of performing sewing with the both surfaces of the workpiece-to-be-sewn being pinched by the sewing mechanism, in the retraction region of the workpiece-to-be-sewn.
