Abstract
In a film supplying device in a package machine, a film drawn out from a film roll is fed downstream between a drive roll and a driven roll. The drive roll is rotatably supported by a first support fixed to a main frame. A second support for rotatably supporting the driven roll is supported on the main frame so as to be rotatable. The second support is movable between a sandwiched position where the driven roll approaches the drive roll to be aligned therewith to hold the film therebetween, and a retract position in which the driven roll is spaced apart from the drive roll.
Claims13
A film supplying device in a horizontal package making and filling machine provided with an approaching angle adjusting device adjusting an approaching angle of a film toward a tube former, the approaching angle adjusting device being provided in a film feed course between a film roll and the tube former, the film supplying device comprising:
- a drive side rotation member provided in the film feed course between the film roll and the approaching angle adjusting device, and extending along a width direction of the film;
- a driven side rotation member that rotates responsive to the drive side rotation member with the film being positioned between the drive side rotation member and the driven side rotation member;
- a first support member fixed to a main body and supporting the drive side rotation member rotatably on both sides in a rotational axial direction of the drive side rotation member;
- a second support member rotatably supporting the driven side rotation member on both sides in the rotational axial direction of the driven side rotation member, and
- a cover member provided on the second support member, a portion of the cover member directed in a vicinity of the drive side rotation member by covering a facing region where the drive side rotation member and the driven side rotation member are configured to contact each other while the second support member is in a sandwiched position;
- wherein the second support member is supported on the main body in such a way as to be movable between the sandwiched position in which the driven side rotation member approaches the drive side rotation member to be aligned therewith to sandwich the film, and a retract position spaced apart from the sandwiched position, and
- the drive side rotation member that moves the second support member to the sandwiched position to sandwich the film with the driven side rotation member is rotated to draw the film downstream from the film roll;
- and
- wherein a support shaft of the driven side rotation member is supported between two side facing walls, whereby rotating an operation lever mounted on one end of the support shaft moves the driven side rotation member away from the drive side rotation member.
A film supplying device in a horizontal package making and filling machine, the film supplying device comprising:
- a main body;
- a first support coupled to the main body, the first support includes:
- a pair of opposing sidewalls;
- and
- a support shaft that extends between the pair of opposing sidewalls;
- a second support moveably coupled to the main body relative to the first support;
- a first roller rotatably coupled to the first support and extending along a first axis that is configured to align with a width direction of a film moving on a film feed course;
- a second roller rotatably coupled to the second support and extending along a second axis, the second roller positioned adjacent to the first roller such that the film feed course passes between the first roller and the second roller;
- and
- an operation lever mounted a first end of the support shaft, the operation lever configured to be actuated such that actuation of the operation lever moves the first roller away from the second roller;
- wherein:
- the second support is movable between:
- a first position in which the second roller contacts the first roller and in which the first axis of the first roller and the second axis of the second roller are parallel;
- and
- a second position in which the second roller does not contact the first roller and in which the second axis of the second roller is angularly disposed relative to the first axis of the first roller;
- the first roller is coupled to and rotatable with the support shaft;
- and
- the first roller is configured to be rotatably driven by a motor to draw the film downstream from a film roll.
