Abstract
A winding machine capable of satisfactorily winding the film material around the second winding core is provided. A winding machine according to the present disclosure includes: a first support part configured to movably support a first winding core in such a manner that it is close to or apart from a feeding roller; a second support part configured to movably support a second winding core in such a manner that it comes into contact with a film material between the first winding core and the feeding roller; and a pulling mechanism configured to pull the film material toward a side of the second winding core so that the film material is wound around the second winding core.
Claims11
A winding machine comprising:
- a first support part configured to rotatably support a first winding core that winds a film material and movably support the first winding core in such a manner that the first winding core is close to or spaced apart from a feeding roller disposed on an upstream side in a direction in which the film material is fed;
- a second support part configured to rotatably support a second winding core that is disposed parallel to the first winding core and winds the film material, and movably support the second winding core in such a manner that the second winding core comes into contact with the film material between the first winding core and the feeding roller in a state where the first winding core is spaced apart from the feeding roller;
- and
- a pulling mechanism configured to pull the film material toward a side of the second winding core so that the film material is wound around the second winding core in a direction in which the second winding core rotates in a state where the second winding core is in contact with the film material between the first winding core and the feeding roller.
The winding machine according to claim wherein
- the first support part revolvably supports the first winding core around a preset rotation axis,
- the second support part revolvably supports the second winding core around the rotation axis, and
- a distance between the rotation axis and a central axis of the first winding core is equal to a distance between the rotation axis and the central axis of the second winding core.
A winding method comprising:
- moving a first winding core that winds a film material so that the first winding core is spaced apart from a feeding roller disposed on an upstream side in a direction in which the film material is fed, and bringing a second winding core disposed parallel to the first winding core into contact with the film material between the first winding core and the feeding roller;
- pulling the film material toward a side of the second winding core by a pulling mechanism so that the film material is wound around the second winding core in a direction in which the second winding core rotates;
- and
- cutting the film material and shifting the winding of the film material from the first winding core to the second winding core.
