Abstract

A winder for forming a yarn package can have a spindle axis. The winder can comprise a spindle that is configured to be rotatably driven about the spindle axis. A color probe can be positioned with respect to the spindle to measure a color value of yarn wound on the spindle.

First claim

What is claimed is:

1 . A winder for forming a yarn package, the winder having a spindle axis and comprising:
a) a spindle that is configured to be rotatably driven about the spindle axis, wherein the spindle is configured to wind the yarn package to have a longitudinal end; and b) a color probe that is positioned with respect to the spindle to measure a color value of yarn wound on the spindle on the longitudinal end of the yarn package.

2 . The winder of claim 1 , wherein the color probe has a measuring direction, wherein the measuring direction of the color probe is within thirty degrees of the spindle axis.

3 . The winder of claim 2 , wherein the measuring direction of the color probe is substantially parallel to the spindle axis.

4 . The winder of claim 1 , wherein the winder is configured to position the color probe within a select radial offset from a circumferential surface of the yarn package on the spindle.

5 . The winder of claim 4 , wherein the spindle is movable on the winder about a rotational axis that is parallel to and offset from the spindle axis, wherein the spindle is configured to move about the rotational axis to maintain a portion of a circumferential surface of the yarn package in a position between select boundaries as the yarn package increases in diameter, wherein the color probe is coupled to the winder in a position proximate to the portion of the circumferential surface of the yarn package that is maintained within the select boundaries.

6 . The winder of claim 1 , wherein the color probe is positioned on the winder to have a spacing that is less than 20 mm from the longitudinal end of the yarn package.

7 . The winder of claim 6 , wherein the color probe is adjustably coupled to the winder to adjust the spacing from the longitudinal end of the yarn package.

8 . The winder of claim 7 , further comprising:
a) a rail that is elongate and extends parallel to the spindle axis, wherein the color probe is coupled to the rail: b) a stepper motor that is configured to move the rail to position the color probe relative to the longitudinal end of the yarn package: c) a range sensor that is configured to determine a distance to the longitudinal end of the yarn package; and d) a controller, wherein the controller is operative to:
i. receive a distance measurement from the range sensor, and
ii. based on the distance measurement, cause the stepper motor to move the rail to adjust the spacing from the color probe to the longitudinal end of the yarn package.

9 . The winder of claim 8 , wherein the range sensor is a laser range sensor.

10 . The winder of claim 1 , further comprising a controller, wherein the controller is operative to: compare a color measurement from the color probe to a predetermined specification, and, in response to measuring the color measurement being outside of a predetermined threshold of the predetermined specification, provide an output.

11 . The winder of claim 10 wherein the output is a signal to an alarm, wherein the alarm is one of a visible or an audible alarm.

12 . The winder of claim 1 , wherein the color value is one of ΔE, ΔΕCMC, ΔL*, ΔL CMC , Δa*, Δb*, ΔC*, Δ 0 , L*, L CMC , a*, b*, C*, or H 0 .

13 . The winder of claim 5 , wherein the winder further comprises a turntable that is configured to rotate about the rotational axis, wherein the spindle is coupled to the turntable.

14 . The winder of claim 13 , wherein the spindle is a first spindle, wherein the winder further comprises a second spindle that is coupled to the turntable.

15 . The winder of claim 1 , wherein the color probe is configured to detect a color of a circumferential surface of the yarn package.

16 . The winder of claim 1 , wherein the color probe is in communication with a computing device that is configured to change at least one parameter of a manufacturing system that is producing the yarn wound around the spindle.
