Abstract
The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.
Claims20
A dispenser, comprising:
- a dispenser housing;
- a supply of sheet material supported within the dispenser housing;
- a feed roller adjacent the supply of sheet material, the feed roller configured to engage and move sheet material from the supply of sheet material along a path for discharge from the dispenser housing;
- a drive motor located within the dispenser housing;
- a drive belt extending between the drive motor and the feed roller, wherein the drive belt is operatively connected to the feed roller at a position between a first end and a second end of the feed roller for transferring power from the drive motor to the feed roller for rotation of the feed roller;
- at least one biasing member coupled to the drive belt or to the drive motor, the at least one biasing member configured to apply a biasing or tension force along the drive belt;
- and
- a controller in communication with the drive motor, the controller including programming configured to drive rotation of the feed roller in response to a signal, wherein the controller controls operation of the drive motor to drive the drive belt to cause rotation of the feed roller sufficient to feed a selected length of the sheet material from the supply of sheet material for discharge from the dispenser housing.
A dispenser, comprising:
- a dispenser housing;
- a supply of sheet material received within the dispenser housing;
- a feed roller rotatably mounted along the dispenser housing adjacent the supply of sheet material so as to receive and feed sheet material from the supply of sheet material along a discharge path, the feed roller defining a circumferential groove;
- a drive system comprising:
- a drive motor;
- a drive belt coupled to drive motor and being at least partially received within the circumferential groove;
- and
- a feed roller pulley at least partially positioned within the circumferential groove that is configured to be engaged by the drive belt for transferring power from the drive motor to the feed roller such that rotation of the drive belt by the drive motor causes rotation of the feed roller;
- and
- wherein the drive motor is selectively actuated to rotate the feed roller sufficient to feed an amount of sheet material from the supply of sheet material sufficient for discharge of a selected length of sheet material from the dispenser housing.
