US 11,235,945 B2 · Device and method for determining the diameter of a yarn balloon formed by a continuous yarn at a workstation of a yarn balloon forming textile machine

Abstract

A device as well as a method for determining the diameter of a yarn balloon (B) formed by a continuous yarn at a workstation (1) of a yarn balloon forming textile machine. The workstation (1) comprises an electromagnetically functioning sensor means (33), designed and arranged in such a way that at least two interruptions of a measuring beam (42) of the sensor means (33) are caused by the yarn (5, 25) forming the yarn balloon (B) during every rotation of the yarn balloon (B) during the operation of the workstation (1), and in that the time interval between the interruptions of the measuring beam (42) can be recorded by the sensor means (33) and used for calculating the diameter of the yarn balloon (B).

A device for determining the diameter of a yarn balloon formed by a continuous yarn at a workstation of a yarn balloon forming textile machine,

characterized in that
the workstation comprises a spindle and an electromagnetically functioning sensor, arranged in such a way that at least two faults of a measuring beam of the sensor are generated by the continuous yarn forming the yarn balloon during the operation of the workstation during every rotation of the yarn balloon, and in that the time interval of the faults of the measuring beam can be recorded by the sensor and used for calculating the diameter of the yarn balloon, wherein the sensor is arranged in such a way that the measuring beam of the sensor extends parallel at a distance from the axis of rotation of the spindle.

Dependencies are inferred from the claim text.
