Abstract
In a film supplying device in a package machine, a film 12 drawn out from a film roll is fed downstream between a drive roll 32 and a driven roll 34. The drive roll 32 is rotatably supported by a first support 38 fixed to a main frame 26. A second support 56 for rotatably supporting the driven roll 34 is supported on the main frame 26 so as to be rotatable. The second support 56 is movable between a sandwiched position where the driven roll 34 approaches the drive roll 32 to be aligned therewith to hold the film 12 therebetween, and a retract position in which the driven roll 34 is spaced apart from the drive roll 32.
Claims5
A film supplying device in a horizontal package making and filling machine provided with an approaching angle adjusting device (49) adjusting an approaching angle of a film (12) toward a tube former (14), the approaching angle adjusting device (49) being provided in a film feed course between a film roll (10) and the tube former (14), the film supplying device comprising:
- a drive side rotation member (32) provided in the film feed course between the film roll (10) and the approaching angle adjusting device (49), and extending along a width direction of the film (12);
- a driven side rotation member (34) that rotates responsive to the drive side rotation member (32) with the film (12) being sandwiched between the drive side rotation member (32) and the driven side rotation member (34);
- a first support member (38) fixed to a main body (26) and supporting the drive side rotation member (32) rotatably on both sides in a rotational axial direction of the drive side rotation member (32);
- and
- a second support member (56) rotatably supporting the driven side rotation member (34) on both sides in the rotational axial direction of the driven side rotation member (34),
- wherein the second support member (56) is supported on the main body (26) in such a way as to be movable between a sandwiched position in which the driven side rotation member (34) approaches the drive side rotation member (32) to be aligned therewith to sandwich the film (12), and a retract position spaced apart from the sandwiched position, and
- the drive side rotation member (32) that moves the second support member (56) to the sandwiched position to sandwich the film (12) with the driven side rotation member (34) is rotated to draw the film (12) downstream from the film roll.
