Abstract
A rolled media dispenser is disclosed. In one example, the dispenser includes a transfer bar for automatically transferring paper from a completely depleted stub roll to a primary roll. In one example, the transfer bar includes a lift member that prevents transfer of the paper from the stub roll to the primary roll when paper in the stub roll is present and includes a cam lift member that prevents the transfer of paper from the stub roll to the primary roll as long as paper from the stub roll is present beneath the cam lift member.
Claims17
A rolled media dispenser comprising:
- (a) a housing defining an interior cavity;
- (b) a primary roll support arrangement;
- (c) a stub roll support arrangement;
- (d) a pinch roller;
- (e) a drum roller;
- (f) an outlet opening;
- and
- (g) a transfer mechanism pivotally mounted within the housing interior cavity, the transfer mechanism having:
- (i) a pivot axis;
- (ii) a pinch member extending in a first direction from the pivot axis;
- (iii) a lift member extending in a second direction from the pivot axis, the lift member holding the pinch member away from the drum roller when a roll of media is held within the stub roll support arrangement;
- (iv) a cam lift member located between the lift member and the pinch member, the cam lift being for preventing rotation of the transfer mechanism such that the pinch member is held away from the drum roller when media from the stub roll exists;
- wherein the pinch member includes a pair of arch-shaped members that reach over the pinch roller and contact the drum roller;
- wherein the pinch member includes a rail member and a plate member extending between the arch-shaped members.
