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.

First claim

What is claimed is:

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 presentation station for presenting one or more discrete sheet products of the sheet material to an end user;
a folding station configured for folding the sheet material downstream of the sheet feeding mechanism and prior to presentation at the presentation station;
a sheet product conveying mechanism configured to convey the one or more discrete sheet products to the presentation station;
a separation mechanism for separating the one or more discrete sheet products from the sheet material, the separation mechanism configured to drive 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;
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 , wherein the sheet product conveying mechanism comprises a pair of pinch rollers.

3. The dispenser of claim 2 , wherein 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.

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

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

6. The dispenser of claim 5 , wherein:
the user interface comprises a hand-wave sensor, and
the controller is configured to facilitate dispensing of a predetermined number of discrete sheet products in response to the signal.

7. The dispenser of claim 6 , further comprising an internal rotary switch configured to be set to the predetermined number of discrete sheet products to be dispensed in response to the signal.

8. The dispenser of claim 6 , wherein the number of requested discrete sheet products associated with the signal is the predetermined number of discrete sheet products to be dispensed in response to the signal.

9. The dispenser of claim 5 , 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.

10. The dispenser of claim 9 , wherein the number of requested discrete sheet products associated with the signal is the predetermined number of discrete sheet products to be dispensed 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 number of requested discrete sheet products associated with the signal is the predetermined number of discrete sheet products to be dispensed in response to the signal.

13. The dispenser of claim 11 , wherein the data further comprises the time between the discrete sheet products entering the presentation station and the absence of discrete sheet products at the presentation station.

14. The dispenser of claim 1 , further comprising a motor operably connected to the controller and configured to drive the sheet feeding mechanism in response to the signal, wherein the data further comprises: a time at which the motor is turned on, a time at which the motor is turned off, a time between the motor bring turned on and the motor bring turned off, or a combination thereof.

15. The dispenser of claim 14 , 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.

16. The dispenser of claim 1 , wherein the sheet material is perforated.

17. The dispenser of claim 1 , wherein the data is stored in a text line item format.

18. The dispenser of claim 1 , wherein the folding station comprises a tucker fold mechanism.

19. The dispenser of claim 1 , wherein the sensor is configured to detect a presence of the sheet material at the folding station.

20. A method of dispensing sheet products, comprising:
feeding a sheet material from a roll via a sheet feeding mechanism;
separating one or more discrete sheet products from the roll via a separation mechanism;
folding the sheet material at a folding station downstream of the sheet feeding mechanism;
dispensing the one or more folded discrete sheet products to an end user 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,
wherein the separation mechanism is configured to drive 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.

21. The method of claim 20 , further comprising transmitting the signal to the controller from a user interface.

22. The method of claim 20 , 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.

23. The method of claim 20 , 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.

24. The method of claim 20 , wherein the folding station comprises a tucker fold mechanism.

25. The method of claim 20 , wherein the sensor is configured to detect a presence of the sheet materia
