Abstract

Systems, methods, and apparatuses regarding an improved sheet product dispenser are provided herein. Example sheet product dispensers include a rotatable carriage that holds two full size product rolls. Upon substantial depletion of one of the product rolls, the sheet product dispenser is configured to enable the carriage to rotate to present the depleted product roll to the janitor for easy and intuitive replacement. For example, a carriage with a depleted product roll may be configured to automatically rotate upon opening of the cover. Additional features for intuitive and reliable installation of the product roll are also provided herein, such as roll holder slot guides and a retention mechanism that maintains installation of a product roll during rotation of the carriage. Such example sheet product dispensers help to eliminate product waste, reduce confusion while loading, and reduce the time and effort required to load the sheet product dispenser.

First claim

The invention claimed is:

1. A product dispenser comprising:
a housing including a base portion and a cover, wherein the cover is movable relative to the base portion to define an open position and a closed position, wherein the base portion extends in a first plane;
a carriage rotatably coupled to the base portion, wherein the carriage defines a first end and a second end, wherein the carriage is rotatable between at least a first orientation and a second orientation, wherein the carriage comprises:
a first roll holder positioned proximate to the first end of the carriage, wherein the first roll holder is configured to receive a first roll of product and enable rotation of the first roll of product about a first axis, wherein the first axis is parallel to the first plane; and
a second roll holder positioned proximate to the second end of the carriage, wherein the second roll holder is configured to receive a second roll of product;
a dispensing mechanism configured to receive a leading edge of one of the first roll of product or the second roll of product and cause dispensing of a portion of the corresponding first roll of product or the second roll of product;
a product sensor configured to sense product data corresponding to at least one of:
dispensing from at least one of the first roll of product or the second roll of product; or
an amount of product remaining for at least one of the first roll of product or the second roll of product; and

a controller configured to:
determine, based on the product data from the product sensor, an instance in which the second roll of product is at least substantially depleted; and
enable rotation of the carriage in an instance in which the second roll of product is at least substantially depleted so as to provide a user access to the second roll holder to enable replacement of the at least substantially depleted second roll of product.

2. The product dispenser of claim 1 , wherein the controller is further configured to, in response to determining an instance in which the second roll of product is at least substantially depleted, cause rotation of the carriage to an intermediate orientation between the first orientation and second orientation.

3. The product dispenser of claim 2 , wherein the carriage is biased to rotate from the intermediate orientation to the second orientation, wherein the cover comprises at least one cover stop that is configured to interact with at least a portion of the carriage when the cover is in the closed position and the carriage has rotated to the intermediate orientation, wherein the cover stop prevents further rotation of the carriage toward the second orientation, and wherein, in an instance in which a user opens the cover, the cover stop is removed from interaction with the portion of the carriage to cause the carriage to automatically rotate to the second orientation.

4. The product dispenser of claim 3 , wherein the carriage comprises a first stop positioned proximate the first end and a second stop positioned proximate the second end, wherein the product dispenser further comprises a release stop that is configured to interact with the second stop of the carriage when the carriage is in the first orientation, wherein the controller is configured to, in response to determining an instance in which the second roll of product is at least substantially depleted, cause the release stop to be removed from interaction with the second stop of the carriage to cause rotation of the carriage to the intermediate orientation, and wherein the first stop of the carriage is configured to interact with the cover stop when the carriage is in the intermediate orientation.

5. The product dispenser of claim 2 further comprising a linkage that defines a release stop and is connected to a transfer mechanism, wherein the release stop is configured to interact with at least a portion of the carriage to prevent rotation of the carriage from the first orientation to the intermediate orientation, wherein the transfer mechanism is configured to transfer the leading edge of the first roll of product to the dispensing mechanism to enable dispensing from the first roll of product, and wherein the controller is configured to, in response to determining an instance in which the second roll of product is at least substantially depleted, simultaneously cause, via movement of the linkage, the release stop to be removed from interaction with the portion of the carriage to cause rotation of the carriage to the intermediate orientation and the transfer mechanism to transfer the leading edge of the first roll of product to the dispensing mechanism.

6. The product dispenser of claim 2 further comprising a transfer mechanism, wherein the transfer mechanism is configured to transfer the leading edge of the first roll of product to the dispensing mechanism to enable dispensing from the first roll of product, wherein the transfer mechanism defines a backplate that includes visual instructions for attaching a leading edge of a roll of product to the transfer mechanism.

7. The product dispenser of claim 2 further comprising a transfer mechanism defining an extension portion, wherein the transfer mechanism is configured to transfer the leading edge of the first roll of product to the dispensing mechanism to enable dispensing from the first roll of product, and wherein the controller is configured to, in response to determining an instance in which the second roll of product is at least substantially depleted, simultaneously cause the transfer mechanism to transfer the leading edge of the first roll of product to the dispensing mechanism and the extension portion to engage the carriage to cause rotation of the carriage from the first orientation to the intermediate orientation.

8. The product dispenser of claim 1 , wherein the carriage is biased by at least one of gravity or one or more biasing elements to rotate from the first orientation to the second orientation.

9. The product dispenser of claim 1 , wherein the cover defines a pull flange that is configured to pull at least a portion of the carriage as the cover opens to cause rotation of the carriage.

10. The product dispenser of claim 1 further comprising at least one motor configured to cause rotation of the carriage, wherein the controller is configured to, in an instance in which the carriage is in the first orientation and the second roll of product is at least substantially depleted, cause the motor to automatically rotate the carriage when the cover is moved to the open position.

11. The product dispenser of claim 1 , wherein, when the cover is in the closed position, the housing and the carriage are each sized such that both of the first roll holder and the second roll holder are configured to each hold a full size roll of product.

12. The product dispenser of claim 1 , wherein the second roll holder defines a bowl shape section that corresponds to the shape of the new roll of product to enable intuitive installation of the new roll of product.

13. The product dispenser of claim 1 , wherein the second roll holder defines a roll holder slot, wherein the roll holder slot is shaped to enable a user to drop a new roll of product into the roll holder slot for easy installation of the new roll of product.

14. The product dispenser of claim 13 , wherein the roll holder slot of the second roll holder includes one or more installation guides to provide instruction to the user regarding how to install the new roll of product into the second roll holder.

15. The product dispenser of claim 13 , wherein the carriage defines a carriage axis of
