Abstract
A sheet product dispenser is provided for sheet product from a roller. The sheet product dispenser includes a first roll of sheet product, called a stub roll, a main roll of sheet product, and a dispensing arrangement. A sensor is provided for detecting when sheet product on a stub roll is depleted. The sensor generates a signal in response to the depletion of the stub roll and a controller activates an electromechanical actuator. The actuator acts to operate a transfer bar that moves an end portion of the main roll sheet product adjacent a roller assembly that engages the main roller sheet product.
Claims28
A method of a dispensing sheet product, said method comprising:
- emitting a light to sense a presence of a first sheet product entering a feed roller assembly;
- generating a signal if said first sheet product is not sensed;
- activating an electromechanical actuator in response to said signal;
- and
- moving a second sheet product first end from a first position to a second position when said electromechanical actuator is activated.
A method of a dispensing sheet product, said method comprising:
- sensing movement of a microswitch indicator between a first position and a second position, to sense a presence of a first sheet product adjacent a feed roller;
- generating a signal if said first sheet product is not sensed;
- activating an electromechanical actuator in response to said signal;
- and
- moving a second sheet product first end from a third position to a fourth position when said electromechanical actuator is activated.
A method of a dispensing sheet product, said method comprising:
- sensing flow of electrical current from a first conductive ring coupled to a feed roller to a second conductive ring coupled to a second roller, to sense a presence or absence of a first sheet product adjacent the feed roller;
- generating a signal if said first sheet product is not sensed;
- activating an electromechanical actuator in response to said signal;
- and
- moving a second sheet product first end from a first position to a second position when said electromechanical actuator is activated.
