Embodiment Construction

[0029] One half of a textile machine (in this embodiment an open-end rotor spinning machine) producing cross-wound bobbins is shown in FIG. 1 , which is generally designated by reference numeral 1 . As is known, such an open-end rotor spinning machine has a large number of similar workstations 2 arranged next to each other in the longitudinal direction of the machine. In this case, the workstation 2 has a spinning device 3 and a winding device 4 . The fiber strip 6 present in the spinning drum 5 is spun into a yarn 7 in the spinning device 3 , which is then wound up on the winding device 4 to form a cross-wound bobbin 8 .

[0030] As shown in FIG. 1 , and as described in more detail below with the aid of FIGS. 2 and 3 , the winding device 4 is in each case equipped with a creel 9 which is acted upon by a loading and unloading device 30 . Empty tubes 10 or cross-wound bobbins 8 are rotatably mounted in the creel 9 and driven by means of drive rollers 11 in a frictional engagemen...

Abstract

The invention relates to a creel loading and relieving device for a winding device of a textile machine producing crosswound bobbins in order to adjust the contact pressure of a take-up bobbin mounted in a creel on a driving roll. Said creel loading and relieving device comprises a creel that is pivotally mounted via a creel shaft and a force applying means which grips the creel and is adjustable via a positioning element. The inventive creel loading and relieving device (30) is provided with an actuator (33) that can be positioned by means of an electromotive drive (40) while a force applying means (29) which impinges upon the creel (9) is disposed on said actuator (33). The force applying means is configured as a pneumatic spring (29) and is hinged to a first lever arm (25) that is connected to a creel yoke (24). The loading or relieving moment to be applied to the creel (9) by the pneumatic spring (29) can be adjusted with precision by positioning the actuator (33) accordingly.

Description

technical field [0001] The invention relates to a creel loading and unloading device for a winding device of a textile machine for producing cross-wound bobbins according to the preamble of claim 1 . Background technique [0002] Such a creel loading and unloading device basically achieves two goals during the production of wound bobbins. On the one hand, they should ensure a minimum contact pressure of the tube (or still relatively light wound bobbin) on the associated drive roller at the start of the bobbin travel, and on the other hand, they should counteract the bobbin weight (bobbin The weight increases as the winding bobbin becomes larger). [0003] Since, besides the yarn tension, the contact pressure also determines the density of the wound bobbin (often called cross-wound bobbin), the aim is to keep the contact pressure as constant as possible during the entire travel of the bobbin. [0004] A creel loading and unloading device is known from DE 25 18 646 C2, in wh...
