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.
Claims15
A dispenser, comprising:
- a dispenser housing;
- a supply of sheet material supported along the dispenser housing;
- a feed roller rotatably mounted along the dispenser housing and having a body configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the dispenser housing;
- a feed roller drive assembly including a drive motor located within the dispenser housing adjacent the body of the feed roller, and a belt transmission assembly having a drive belt coupled to the drive motor and to the body of the feed roller such that rotation of the feed roller is driven by operation of the drive motor, the drive belt being operatively connected to the body of the feed roller at a position that is between a first end and a second end of the body of the feed roller;
- and
- a controller in communication with the drive motor to drive rotation of the feed roller in response to a signal, wherein the controller controls operation of the drive motor to rotate the feed roller sufficient to feed a desired length of the sheet material from the supply of sheet material through the discharge wherein the feed roller drive assembly further comprises a drive motor pulley operatively attached to a driveshaft of the drive motor, and
- wherein the drive belt is received about and operably engages the feed roller and the drive roller pulley for transferring power from the drive motor to the feed roller for driving rotation thereof;
- a feed roller pulley at least partially positioned within a circumferential groove defined along the body of the feed roller and engaged by the drive belt feed roller.

A dispenser, comprising:
- a dispenser housing;
- a supply of sheet material rotatably mounted along the dispenser housing;
- a feed roller comprising a feed roller body 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 through a discharge along the dispenser housing;
- and
- a feed roller drive assembly including a drive motor, and a belt transmission assembly having a drive belt coupled to drive motor and to the feed roller body to facilitate rotation of the feed roller by operation of the drive motor, the drive belt being at least partially received within a circumferential groove defined along the feed roller body a drive motor pulley operatively attached to a driveshaft of the drive motor;
- and
- a feed roller pulley received within the circumferential groove;
- wherein the drive belt is at least partially received about and operably engages the feed roller pulley and the drive roller pulley for transferring power from the drive motor to the feed roller for driving rotation thereof.

- a tensioned motor mounting assembly including:
- a base movably mounted to the dispenser housing;
- a support frame that is connected to the base, and at least partially supports the drive motor;
- and
- one or more biasing members connected to the base or the support frame to bias the tensioned motor mounting assembly for providing tension along the drive belt and/or for providing dampening for the feed roller drive assembly.
