Abstract
A device for determining the diameter of a yarn balloon (B) formed by a running yarn at a workstation (1) of a textile machine wherein the workstation (1) is provided with a mechanical, contact scanning sensor (22), which is designed and arranged so that during the operation of the workstation (1) it is positioned by a yarn forming the thread balloon (B) in an operating position dependent on the diameter of a thread balloon (B), and a sensor device (24) is provided which detects the operating position (BS) of the scanning sensor (22).
Claims17
Device for determining the diameter of a thread balloon (B) formed by a running thread at a workstation (1) of a textile machine, wherein the textile machine having a plurality of workstations (1), each of which having a device (6) for influencing a yarn tension of the outer thread (5), which device (6) is connected to a control circuit (18), a spindle (2), a spindle pot (19) for receiving a second feed bobbin (15), a rotatable thread guiding device (20), a balancing system (9) for forming a cabling or cording point and a spooling and winding device (12),
- characterised in that
- the workstation (1) has a mechanical, contact scanning sensor (22) which is designed and mounted pivotably so that during the operation of the workstation (1) a position of the scanning sensor (22) is changed by a yarn forming the thread balloon (B) to an operating position (BS) dependent on the diameter of the thread balloon (B), and
- in that the workstation (1) has a sensor device (24) which senses the operating position (BS) of the scanning sensor (22).
Device according to any one of the preceding claims, characterised in that the scanning sensor (22) in the area in which is it is tangential to the thread balloon (B) has a pointy curvature (31, 31B) extending toward a perimeter of the thread balloon (B).
Method for determining the diameter of a thread balloon (B) formed by a running outer thread (5) on a workstation (1) of a textile machine, wherein the textile machine having a plurality of workstations (1), each of which having a device (6) for influencing a yarn tension of the outer thread (5), which device (6) is connected to a control circuit (18), a spindle (2), a spindle pot (19) for receiving a second feed bobbin (15), a rotatable thread guiding device (20), a balancing system (9) for forming a cabling or cording point and a spooling and winding device (12),
- characterised in that
- the workstation (1) has a mechanical, contact scanning sensor (22) which is designed and arranged so that during the operation of the workstation (1) it is positioned by a yarn forming the thread balloon (B) in an operating position (BS) dependent on the diameter of the thread balloon (B), and
- the operating position (BS) of the scanning sensor (22), which is predefined by the diameter of the thread balloon (B), is sensed by a sensor device (24) provided with the workstation (1).
