Abstract

An automatic electronic dispenser for dispensing a roll of paper product that avoids refeeding of paper by retarding breaking on the high side of the roll. A dispenser module drives paper from the roll through a discharge chute at the bottom of the module. The dispenser module utilizes two floating pressing rollers and a belt drive that provides quiet and consistent operation by pressing of the two pressing rollers onto a main roll. The dispenser module including a main bar module which holds the roll and which is received on paper holder arms.

Claims

1. An automatic dispenser for dispensing a roll of a perforated paper product, the dispenser comprising:

a paper roll support upon which the roll of perforated paper sheets is disposed, the paper roll support including a plurality of paper holder arms attached along opposite sides of the paper roll support, and shaped to receive the paper roll therebetween;

a driving roller for unrolling the paper from the paper roll holder in response to a signal;

a series of pressing rollers, the pressing rollers each arranged so as to engage the perforated paper sheets against the driving roller as the driving roller is driven so as to draw the paper sheets along a feed path defined between the pressing and driving rollers and to a discharge; and

a drive mechanism including a drive motor operatively connected to a belt drive gear and to at least one end of the driving roller, and at least one drive belt driven by the belt drive gear that engages the pressing rollers in a substantially tensioned arrangement to drive the pressing rollers with the driving roller so as to facilitate drawing of the perforated paper therebetween;

wherein the drive motor is actuated in response to a signal and drives the driving and pressing rollers for a predetermined number of cycles for feeding an amount of the perforated paper product from the roll.

2. The automatic dispenser of claim 1 wherein the driving roller and the pressing rollers are formed from wood to reduce static electricity.

3. The automatic dispenser of claim 1 wherein the driving roller includes a plurality of sections with each section separated from an adjoining section by a spacer section.

4. The automatic electronic dispenser of claim 1 wherein each pressing roller includes a plurality of sections with each section separated from an adjoining section by a spacer section.

5. The automatic dispenser of claim 1 wherein the drive belt comprises a non-slip material that substantially resists elongation, and wherein the belt drive gear and the plurality of pressing rollers comprise grooves formed about a periphery thereof within which the drive belt is received.

6. The automatic dispenser of claim 1 further comprising an electronic sensor located on a dispenser module for detecting the proximity of a user.

7. The automatic dispenser of claim 1, further comprising end caps with surfaces receivable in slots defined in each of the paper holder arms.

8. An automatic dispenser for dispensing a roll of a perforated paper product, comprising:

a paper roll support upon which the roll of perforated paper sheets is disposed, the paper roll support including a plurality of paper holder arms attached along opposite sides of the paper roll support, and shaped to receive the paper roll therebetween;

a driving roller for unrolling the paper from the paper roll holder in response to a signal;

a series of pressing rollers each arranged to engage the perforated paper sheets against the driving roller as the driving roller is driven to draw the paper sheets along a feed path defined between the pressing and driving rollers towards a discharge;

a drive mechanism including a drive motor operatively connected to a belt drive gear and the driving roller, and at least one drive belt driven by the belt drive gear and engaging the pressing rollers to drive the pressing rollers; and

gearbox mechanism operatively connected to the drive motor and the driving roller to transfer power therebetween.

9. An electronic dispensing system for automatically dispensing and monitoring usage of a paper product, comprising:

at least one dispenser having a dispenser module for driving paper from a roll of the paper product through a discharge, the roll being disposed on paper holder arms, each dispenser module including;

a driving roller for unrolling the paper from a paper roll holder;

a pair of driven pressing rollers, the pressing rollers arranged to each engage the paper against the driving roller to assist in feeding the paper along a feed path between the pressing and driving rollers and to the discharge;

a drive belt extended about a peripheral end of each of the pressing rollers; and

a drive motor operatively connected to a transmission arrangement for driving the driving roller and for driving the drive belt that engages the pressing rollers to be driven in cooperative movement with the operation of the driving roller to substantially maintain engagement of the paper at multiple points thereby facilitating feeding of the paper, wherein the drive motor is activated in response to a signal from a sensor so as to drive the driving roller and the pressing rollers to feed the paper from the roll.

10. The electronic dispensing system of claim 9 wherein the at least one dispenser comprises a plurality of dispensers, each of which further comprises a microprocessor controller and a transceiver.

11. The electronic dispensing system of claim 10 further comprising:

a master network device operatively connected with the transceiver in each dispenser; and

a local network for enabling a paper product status message to be transmitted from each dispenser to the master network device.

12. The electronic dispensing system of claim 11 further comprising an automation and control network interoperable with the local network for monitoring a status of each dispenser.

13. The electronic dispensing system of claim 12 wherein the master network device receives status messages from the transceiver in each dispenser and transmits status messages over the automation and control network.

14. The electronic dispensing system of claim 11 wherein the microprocessor controller for each dispenser determines an amount of paper remaining on the paper roll holder mechanism and transmits a status message signal containing a status of the paper product to the master network device.

15. The electronic dispenser of claim 9 wherein the driving roller and the driven pressing rollers are manufactured from wood to reduce static electricity.

16. The electronic dispenser of claim 9 wherein the driving roller includes a plurality of sections with each section separated from an adjoining section by a spacer section.

17. The electronic dispenser of claim 9 wherein each pressing roller includes a plurality of sections with each section separated from an adjoining section by a spacer section.

18. The electronic dispenser of claim 9 wherein the drive belt comprises a non-slip material that substantially resists elongation, and wherein the belt drive gear and the plurality of pressing rollers comprise grooves formed about a periphery thereof within which the drive belt is received.

19. The electronic dispenser of claim 9 wherein the transmission comprises a gearbox mechanism including a plurality of intermeshing gears.
