Problems solved by technology

[0015] This splicing device, which can be configured according to the yarn material to be processed, has proven itself in round-the-clock operation, but has the serious disadvantage that in order to be able to guarantee the correct Inventory of different splice prisms on a very large scale
[0016] In addition, in such yarn splicing devices there is always the risk that, during reconstruction measures, incorrect components are inserted accidentally or components are installed inappropriately
In both cases, the result is very unfavorable for the yarn connection to be done subsequently

Embodiment Construction

[0041] figure 1 The station 2 of a textile machine for producing cross-wound bobbins, in the present exemplary embodiment an automatic winder 1 , is schematically shown in side view.

[0042] Such an automatic winder 1 actually has, between its end frames (not shown), a plurality of such stations 2 of generally identical construction arranged next to one another.

[0043] At station 2, also often referred to in industry circles as the "winding unit", the unwound bobbins, such as bobbins with less yarn material produced on ring spinning machines, are rewound into large packages. The bobbin 15 is cross wound.

[0044]After production, the cross-wound bobbins 15 are transferred to a cross-wound bobbin conveyor 21 along the machine length and from there to a bobbin loading station arranged at the machine end side.

[0045] In this embodiment, the automatic winder 1 is also equipped with its own logistics in the form of a bobbin and empty tube delivery system 3, figure 1 Only th...

Abstract

The invention relates to a yarn splicing device (10) for a station (2) of an automatic winder (1), for connecting two yarn ends without knots, comprising a yarn splicing prism (23), the yarn splicing The prism has a yarn splicing channel (27) which is exposed to the air flow and is open upwards during the yarn splicing operation, in which yarn end is positioned during the yarn splicing operation. According to the invention, the yarn joining prism (23) is adjustably mounted on the stationary air distribution body (17) such that the central axis (34) of the yarn joining channel (27) of the yarn joining prism (23) The angular position of is adjustable with respect to the angular position of the conventional yarn path (30) of this station (2).

Description

technical field [0001] The invention relates to a yarn splicing device for knot-free joining of two yarn ends for a station of an automatic winder, comprising a yarn splicing prism with a yarn splicing open upwards during the yarn splicing operation and receiving the effect of an air flow A channel in which the yarn end is positioned during the yarn joining operation. Background technique [0002] In connection with the operation of the stations of textile machines producing cross-wound bobbins, and especially of automatic winders, the use of yarn splicing devices for pneumatically joining yarns has long been known and is clearly described in numerous patent documents. [0003] With such a yarn splicing device, two yarn ends that occur after a winding interruption, such as after a yarn break or a controllable yarn clearer, can be connected again by air flow, so that almost the same connection point as the yarn occurs. [0004] For this purpose, the so-called upper yarn that...
