Abstract

Sheet product dispensers and methods are provided. A sheet product dispenser includes a loading station for sheet material, a sheet feeding mechanism configured to feed the sheet material, a presentation station for presenting one or more discrete sheet products to an end user, a sensor downstream of the feeding mechanism and upstream of the presentation station configured to detect a presence of the discrete sheet products, and a controller configured to facilitate dispensing of the one or more discrete sheet products in response to a signal, and to determine and store data associated with the dispensing of the sheet products.

Claims

1. A sheet product dispenser, comprising:

a loading station for loading a roll of sheet material;

a sheet feeding mechanism configured to feed sheet material from the roll;

a separation mechanism for separating one or more discrete sheet products from the roll of sheet material;

a presentation station for presenting the one or more discrete sheet products to an end user;

a sheet product conveying mechanism configured to convey the one or more discrete sheet products to the presentation station;

a sensor downstream of the sheet feeding mechanism and upstream of the sheet product conveying mechanism, the sensor being configured to detect a presence of the sheet material; and

a controller configured to facilitate dispensing of the one or more discrete sheet products to the presentation station in response to a signal, the controller also being configured to receive and store data comprising data associated with the sensor.

2. The dispenser of claim 1, further comprising a folding station for providing a fold or crease in the one or more discrete sheet products downstream of the sheet feeding mechanism and prior to presentation at the presentation station.

3. The dispenser of claim 2, wherein the folding station comprises a tucker fold mechanism.

4. The dispenser of claim 2, wherein the sheet product conveying mechanism comprises a pair of pinch rollers and the folding station comprises a buckle chamber adjacent to the pair of pinch rollers, such that a portion of the sheet material enters the buckle chamber and a fold in the sheet material is forced through the pair of pinch rollers.

5. The dispenser of claim 2, wherein the sensor is configured to detect a presence of the sheet material at the folding station.

6. The dispenser of claim 1, wherein the separation mechanism comprises a cutting mechanism or a speed differential separation mechanism.

7. The dispenser of claim 6, wherein the speed differential separation mechanism comprises the sheet feeding mechanism being driven at a first speed and the sheet product conveying mechanism being driven at a second speed that is higher than the first speed.

8. The dispenser of claim 1, wherein the sensor is an infrared sensor.

9. The dispenser of claim 1, further comprising a user interface configured to transmit the signal to the controller.

10. The dispenser of claim 9, wherein:

the user interface comprises one or more buttons, each button being associated with a predetermined number of discrete sheet products to be dispensed in response to the signal, and

the controller is configured to facilitate dispensing of the predetermined number of discrete sheet products associated with a selected button in response to the signal being transmitted from the selected button.

11. The dispenser of claim 1, further comprising a second sensor configured to detect an absence of discrete sheet products at the presentation station, and transmit the signal to the controller upon detection of the absence of discrete sheet products at the presentation station, wherein the controller is configured to facilitate dispensing of a predetermined number of discrete sheet products in response to the signal.

12. The dispenser of claim 11, wherein:

the data comprises a number of requested discrete sheet products associated with the signal and a number of discrete sheet products associated with the sheet material detected by the sensor, and

the controller is configured to compare the number of requested discrete sheet products associated with the signal and the number of discrete sheet products associated with the sheet material detected by the sensor, and turn off the motor when the number of discrete sheet products associated with the sheet material detected by the sensor matches the number of requested discrete sheet products associated with the signal.

13. A method of dispensing sheet products, comprising:

feeding sheet material from a roll via a sheet feeding mechanism;

separating one or more discrete sheet products from the roll via a separation mechanism;

dispensing the one or more discrete sheet products at a presentation station via a sheet product conveying mechanism, in response to a signal received by a controller;

detecting a presence of the sheet material via a sensor downstream of the sheet feeding mechanism and upstream of the sheet product conveying mechanism; and

collecting and storing data comprising data associated with the sensor.

14. The method of claim 13, further comprising folding the sheet material at a folding station downstream of the sheet feeding mechanism.

15. The method of claim 14, wherein folding the one or more discrete sheet products comprises feeding a portion of the sheet material to a buckle chamber adjacent to the sheet product conveying mechanism and forcing a fold in the sheet material through the sheet product conveying mechanism, wherein the sheet product conveying mechanism comprises a pair of pinch rollers.

16. The method of claim 14, wherein the sensor is configured to detect a presence of the sheet material at the folding station.

17. The method of claim 13, wherein the separation mechanism comprises a cutting mechanism or a speed differential separation mechanism.

18. The method of claim 17, wherein the speed differential mechanism comprises driving the sheet feeding mechanism at a first speed and the sheet product conveying mechanism at a second speed that is higher than the first speed.

19. The method of claim 13, further comprising transmitting the signal to the controller from a user interface.

20. The method of claim 13, further comprising:

detecting an absence of discrete sheet products at the presentation station; and

transmitting the signal to the controller upon detection of the absence of discrete sheet products at the presentation station,

wherein the dispensing comprises dispensing a predetermined number of discrete sheet products in response to the signal.
