Problems solved by technology

However, friction in the gearbox and temperature variations in the motor often lead to errors here
Gearboxes with spur gears or toothed belts usually have too much play or elasticity and for this reason they are rather unsuitable for precise control of contact forces

Embodiment Construction

[0033] figure 1 A partial perspective view of the yarn processing machine 10 is shown. The yarn processing machine 10 has a machine frame 12 on which a plurality of winding heads 14 are arranged side by side. The winding heads 14 each have a winding device 16 for winding a yarn 20 provided on a supply package 18 onto a package tube 22 to form a yarn winding package 24 (i.e. , package being wound). Via the yarn guide mechanism 26 of the traversing unit 28 positioned on the machine frame 12, the yarn 20 traveling to the package tube 22 can be guided in a fixed direction relative to the package tube 22 in the direction of the longitudinal axis 30 of the package tube 22. The traversing unit 28 is reciprocally fed within a predetermined or variably predetermined angle range.

[0034] Here, the traversing unit 28 has, for example, a traction-guided thread guide 32 . According to exemplary embodiments not shown in detail in the figures, the traversing unit 28 may also be embodied...

Abstract

The invention relates to a winding device (16) for winding a thread (20) onto a bobbin tube (22) in order to form a thread coil (24). The winding device comprises a spindle (34) for holding and rotating the bobbin tube (22) about its longitudinal axis (30) and a support roller (40) which rests against the circumferential surface of the thread coil (24) while the thread (20) is being wound. The spindle (34) together with the thread coil (24) can be pivoted relative to the support roller (40) by means of at least one pivotally mounted pivot arm (46). The winding device has a pressing force regulating device (54) comprising an actuator (56) for the pivot arm (46), a controller (58) for actuating the actuator (56), and a bending bar-type load cell (60) paired with the pivot arm (46). The loadcell is used to determine a respective actual value of the pressing force FA of the thread coil (24) against the support roller (40), said actual value being used to regulate the pressing force FA toa specified target value by means of the controller (58) by correspondingly actuating the actuator (56). The invention further relates to a thread processing machine (10) comprising the aforementionedwinding device (16).

Description

technical field [0001] The invention relates to a winding device with support rollers and a contact force control device and to a yarn processing machine. Background technique [0002] In practice, threads, textile yarns, fibers etc. (hereinafter referred to as yarns) made of natural or synthetic materials are wound into so-called bobbins for further processing, including in particular for dyeing processes (package tube) to form a yarn package (also known as a yarn winding package). For example, this can be done by means of cross-winding. For this purpose, a winding device with a spindle for rotatably supporting the winding tube is used. The spindle can be driven in rotation by means of a spindle drive. During winding, the support roller typically rests against the outer peripheral surface of the yarn winding package. The spindle drive can be designed according to the known type in the form of a friction roller drive, in which a motor-driven support roller acts as a fric...
