Abstract
A roller storage system (1) for sheet-type media has at least one film drum (5) driveable by a motor with at least one strip-type film (5) and at least one winding drum (4) with a central drive spindle (8) driveable by a motor, wherein the strip-type film (5) can be wound onto the winding drum (4), where the winding drum (4) is carried floating on the drive spindle (8).
Claims18
Roller storage system for sheet-type media, comprising:
- at least one film drum including at least one strip-type film;
- a central drive spindle drivable by a motor;
- a first fixed disc and a second fixed disc each integral with the central drive spindle and fixedly mounted near opposite ends of the central drive spindle;
- a first movable disc and a second movable disc each integral with the central drive spindle and slidably movable on the central drive spindle along a longitudinal axis thereof, the first movable disc is proximate to the first fixed disc and the second movable disc is proximate to the second fixed disc;
- a first spring mounted to the central drive spindle between the first fixed disc and the first movable disc, and a second spring mounted to the central drive spindle between the second fixed disc and the second movable disc;
- and
- at least one winding drum mounted to the central drive spindle between the first movable disc and the second movable disc, where the strip-type film can be wound onto the winding drum, the winding drum is slidably movable along the longitudinal axis of the central drive spindle.

A roller storage system for sheet-type media, comprising:
- a first drive spindle drivable by a motor;
- a first movable disc and a second movable disc each integral with the first drive spindle, and slidably movable on the first drive spindle along a longitudinal axis thereof;
- a winding drum mounted to the first drive spindle between the first movable disc and the second movable disc, the winding drum is slidably movable along the longitudinal axis of the first drive spindle;
- a film drum mounted to a second drive spindle;
- and
- a strip-type film extending between the film drum and the winding drum and configured to be wound onto and off of each of the winding drum and the film drum upon rotation of the first drive spindle and the second drive spindle;
- wherein movement of the winding drum along the longitudinal axis is dampened through contact with the first movable disc and the second movable disc.
4 more elements
A roller storage system for sheet-type media comprising:
- a first drive spindle;
- a first spring wound onto the first drive spindle proximate to a first end thereof, the first spring is compressible between a first movable disc and a first fixed disc that are both integral with the first drive spindle, the first movable disc is slidably movable on the first drive spindle along a longitudinal axis thereof, the first fixed disc is fixedly mounted to the first drive spindle;
- a second spring wound onto the first drive spindle proximate to a second end thereof that is opposite to the first end, the second spring is compressible between a second movable disc and a second fixed disc that are both integral with the first drive spindle, the second movable disc is slidably movable on the first drive spindle along the longitudinal axis thereof, the second fixed disc is fixedly mounted to the first drive spindle;
- a winding drum mounted to the first drive spindle between the first movable disc and the second movable disc, the winding drum is spaced apart from each of the first spring and the second spring, a first flange of the winding drum is configured to cooperate with the first movable disc and a second flange of the winding drum is configured to cooperate with the second movable disc;
- a film drum mounted to a second drive spindle;
- and
- a strip-type film extending between the film drum and the winding drum and configured to be wound onto and off of each of the winding drum and the film drum upon rotation of the first drive spindle and the second drive spindle;
- wherein upon movement of the winding drum along the longitudinal axis of the first drive spindle, the first flange of the winding drum contacts the first movable disc to move the first movable disc toward the first fixed disc and compress the first spring therebetween, subsequent decompression of the first spring returns the winding drum to a center position on the longitudinal axis.
