Abstract
A traversing unit for traversing a yarn with respect to a pair of delivery rollers of a workstation of a textile machine includes a yarn-guiding unit, a single traversing drive configured with the yarn-guiding unit, and a conversion element configured with the single traversing drive such a rotational movement (ω) of the single traversing drive is converted into a linear, reciprocating movement of the yarn-guiding unit. The single traversing drive is a rotating motor. A sensor is disposed to detect at least a middle position of the yarn-guiding unit.
Claims14
A traversing unit for traversing a yarn with respect to a pair of delivery rollers of a workstation of a textile machine, comprising:
- a yarn-guiding unit;
- a single traversing drive at the workstation configured with the yarn-guiding unit, wherein each workstation of the textile machine has a respective single traversing drive;
- a conversion element configured with the single traversing drive such that a rotational movement (w) of the single traversing drive is converted into a linear, reciprocating movement of the yarn-guiding unit;
- the single traversing drive comprising a rotating motor;
- and
- a sensor disposed at the workstation to detect at least a middle position (M) of the yarn-guiding unit.
A traversing unit for traversing a yarn with respect to a pair of delivery rollers of a workstation of a textile machine, comprising:
- a yarn-guiding unit;
- a single traversing drive configured with the yarn-guiding unit;
- a conversion element configured with the single traversing drive such that a rotational movement (w) of the single traversing drive is converted into a linear, reciprocating movement of the yarn-guiding unit;
- the single traversing drive comprising a rotating motor;
- a sensor disposed to detect at least a middle position (M) of the yarn-guiding unit;
- and
- wherein the yarn-guiding unit comprises one or both of a cutting unit and a blowing unit, with the aid of which the yarn can be cut in two or a yarn end can be blown into the workstation.
A method for operating a traversing unit of a workstation of a textile machine, comprising:
- guiding a moving yarn in a yarn-guiding unit of the traversing unit and moving the yarn-guiding unit linearly back and forth with a single traversing drive at the workstation and a conversion element to traverse the yarn with respect to a pair of delivery rollers, wherein each workstation of the textile machine has a respective single traversing drive;
- operating the single traversing drive as a rotating motor;
- and
- detecting a middle position (M) of the yarn-guiding unit with the aid of a sensor.
A method for operating a traversing unit of a workstation of a textile machine, comprising:
- guiding a moving yarn in a yarn-guiding unit of the traversing unit and moving the yarn-guiding unit linearly back and forth with a single traversing drive and a conversion element to traverse the yarn with respect to a pair of delivery rollers;
- operating the single traversing drive as a rotating motor;
- detecting a middle position (M) of the yarn-guiding unit with the aid of a sensor;
- and
- wherein during an interruption of the moving yarn, the yarn-guiding unit is positioned at the workstation such that the yarn-guiding unit is aligned with a draw-off tube of the workstation.
