Sheet product dispenser
A sheet product dispenser includes a transfer bar, a roller assembly, a motor, a sensor, and a controller. The transfer bar is movable between first and second positions. The roller assembly, disposed proximate the transfer bar second position, has a drive roller and a pinch roller that define a nip. The motor is in operable communication with the transfer bar to move the transfer bar between the first and second positions. The sensor is in operable communication with the dispenser cover. The controller is in operable communication with the sensor and the motor, and is responsive to executable instructions to facilitate actuation of the motor in response to a signal from the sensor to cause the transfer bar to move between the first position and second positions. The transfer bar includes at least one finger that drives an end of a roll of sheet product towards the nip upon actuation of the transfer bar from the first position to the second position.
1. A method of operating an electronic sheet product dispenser, comprising:
receiving a signal, at a processor of the dispenser, that a motor of the dispenser is powered up such that the motor is operable to dispense sheet product in response to a user request for sheet product;
upon receiving the signal, determining whether sheet product is available for dispensing;
upon determining that sheet product is not available for dispensing, activating a transfer bar; and
activating a roller assembly to position sheet product for dispensing.
2. The method of claim 1 , further comprising:
repeating the steps of determining whether sheet product is available for dispensing and activating the transfer bar, until it is determined that sheet product is available for dispensing, but not more than a predetermined number of times.
3. The method of claim 2 , wherein the predetermined number of times is four.
4. The method of claim 2 , wherein the predetermined number of times is three.
5. The method of claim 1 , wherein determining whether sheet product is available for dispensing comprises sensing, via an optical sensor, whether sheet product is present in a dispensing slot of the dispenser.
6. The method of claim 1 , wherein:
determining whether sheet product is available for dispensing comprises sensing, via an optical sensor, whether sheet product is present in an area between the roller assembly and a dispensing slot of the dispenser, and
the optical sensor comprises an optical emitter arranged to transmit a light to an optical receiver.
7. The method of claim 1 , wherein the signal is received at the processor upon replacement of batteries of the dispenser.
8. The method of claim 1 , wherein the user request for sheet product comprises actuation of a manual sheet product feed button or activation of a proximity sensor.
9. A method of operating an electronic sheet product dispenser, comprising:
receiving a signal, at a processor of the dispenser, that a motor of the dispenser is powered up such that the motor is operable to dispense sheet product in response to a user request for sheet product;
upon receiving the signal, determining whether sheet product is available for dispensing;
upon determining that sheet product is not available for dispensing, activating a transfer bar; and
activating a roller assembly to position sheet product for dispensing,
wherein the steps of determining whether sheet product is available for dispensing and activating the transfer bar are repeated until it is determined that sheet product is available for dispensing, but not more than a predetermined number of times.
10. The method of claim 9 , wherein the predetermined number of times is three.
11. The method of claim 9 , wherein the predetermined number of times is four.
12. The method of claim 9 , wherein determining whether sheet product is available for dispensing comprises sensing, via an optical sensor, whether sheet product is present in a dispensing slot of the dispenser.
13. The method of claim 9 , wherein:
determining whether sheet product is available for dispensing comprises sensing, via an optical sensor, whether sheet product is present in an area between the roller assembly and a dispensing slot of the dispenser, and
the optical sensor comprises an optical emitter arranged to transmit a light to an optical receiver.
14. The method of claim 9 , wherein the signal is received at the processor upon replacement of batteries of the dispenser.
15. The method of claim 9 , wherein the user request for sheet product comprises actuation of a manual sheet product feed button or activation of a proximity sensor.
