Abstract

A sensor assembly configured to detect rolled stock on a core includes a sensor configured to detect a first roll of stock unwinding from a core, the stock unwinding from the core of the first roll is supplied as a web of stock, wherein in response to the sensor detecting a first detection configuration, the sensor takes no action and continues to detect the first roll, and wherein in response to the sensor detecting a second detection configuration, the sensor provides a command to a splice assembly to transition to a second roll of stock to replace the first roll of stock.

First claim

What is claimed is:

1. A sensor assembly configured to detect rolled stock on a core comprising:
a sensor configured to detect a first roll of stock unwinding from a core, the stock unwinding from the core of the first roll is supplied as a web of stock,
wherein in response to the sensor detecting a first detection configuration, the sensor takes no action and continues to detect the first roll,
wherein in response to the sensor detecting a second detection configuration, the sensor provides a command to a splice assembly to transition to a second roll of stock to replace the first roll of stock, and
wherein the first detection configuration includes detecting the stock on the core and the second detection configuration includes detecting the core.

2. The sensor assembly of claim 1 , wherein the core defines an axis of rotation, the sensor is oriented relative to the first roll perpendicular to the axis of rotation.

3. The sensor assembly of claim 1 , wherein the first detection configuration includes detecting a first quantity of stock on the core, the first quantity of stock is above a preprogrammed low level threshold.

4. The sensor assembly of claim 3 , wherein the second detection configuration includes detecting a second quantity of stock on the core, the second quantity of stock does not exceed the preprogrammed low level threshold.

5. The sensor assembly of claim 4 , wherein the core defines an axis of rotation, the sensor is oriented relative to the first roll parallel to the axis of rotation.

6. The sensor assembly of claim 4 , wherein the sensor is configured to detect a portion of the first roll of stock including the core.

7. The sensor assembly of claim 4 , wherein the sensor utilizes machine vision to detect the first and second quantity of stock on the core.

8. The sensor assembly of claim 7 , wherein the machine vision captures volumetric data of the stock on the core.

9. The sensor assembly of claim 7 , wherein the machine vision captures geometric data of the stock on the core.

10. The sensor assembly of claim 4 , wherein the preprogrammed low level threshold corresponds to no more than five impressions of rolled stock remain on the core.

11. The sensor assembly of claim 4 , wherein the preprogrammed low level threshold corresponds to no more than three impressions of rolled stock remain on the core.

12. The sensor assembly of claim 1 , wherein the sensor includes a light source configured to illuminate a portion of the first roll.

13. The sensor assembly of claim 1 , wherein in response to the transition to the second roll of stock, no more than five impressions of rolled stock remain on the core.

14. The sensor assembly of claim 1 , wherein in response to the transition to the second roll of stock, no more than three impressions of rolled stock remain on the core.

15. The sensor assembly of claim 1 , wherein in response to the transition to the second roll of stock, between 1.5 and 2 impressions of rolled stock remain on the core.

16. A sensor assembly configured to detect rolled stock on a core comprising:
a sensor configured to detect a first roll of stock unwinding from a core, the stock unwinding from the core of the first roll is supplied as a web of stock,
wherein in response to the sensor detecting a first detection configuration, the sensor takes no action and continues to detect the first roll,
wherein in response to the sensor detecting a second detection configuration, the sensor provides a command to a splice assembly to transition to a second roll of stock to replace the first roll of stock, and
wherein the sensor is configured to communicate with a manual splice actuation system.

17. The sensor assembly of claim 16 , wherein the manual splice actuation system is configured to initiate a splice in response to the command from the sensor to transition from the first roll to the second roll to provide a continuous web of stock.

18. The sensor assembly of claim 16 , wherein the sensor is configured to communicate with the manual splice actuation system to bypass an automatic splice actuation system.
