Problems solved by technology

[0025] But because of the limited space in the area of ​​the cross-winding automatic winder stations, the use of yarn splicing devices at stations with closed yarn guide channels is still more efficient than in the case of stations with open yarn paths. Difficulty

Embodiment Construction

[0044] exist figure 1 2 shows a schematic side view of a textile machine 1 for producing cross-wound bobbins, in this example a station 2 of a cross-wound automatic winder.

[0045] As is known, such a cross-winding automatic winder 1 has a number of such identical stations 2 arranged side by side between its end frames (not shown).

[0046] At station 2, the unwinding bobbin (such as the bobbin 9 produced on a ring spinning machine not shown upstream in the manufacturing process) is rewound into a large package cross-winding bobbin 15, which is cross-wound After its completion it is transferred to a cross-wound bobbin conveyor 21 along the length of the machine by means of a maintenance device working automatically (also not shown).

[0047] Such a cross-winding automatic winder 1 generally also has a central control unit 11 , which is connected to the station computer 29 of the individual station 2 , for example via a machine bus 16 .

[0048] In the embodiment, the cross-...

Abstract

The invention relates to a yarn joining device (10) used for a station (2) of a textile machine (1) for manufacturing cross-wound bobbins. The yarn joining device has an air distribution body (18) equipped with joint holes (19, 23) used for compressed air pipelines (26, 27), an accommodating hole (30) used for a holding and opening pipe (17) and a yarn joining prism (34), the yarn joining prism has a yarn joining channel (35) to which compressed air can be applied, and a plurality of yarn processing mechanisms, particularly yarn cutting mechanisms (36A, 36B), yarn clamping mechanisms (37A, 37B) and a yarn inlet device (38) are arranged at a distance from the yarn joining prism (34), and can be controlled through driving devices. The invention provides that at least two rotatably mounted control members (41, 42) capable of receiving action each through an independent driving device (39, 40) in a limited manner are arranged on the air distribution body (18), and by virtue of the controlmembers, the yarn processing mechanisms, particularly the yarn cutting mechanisms (36A, 36B), the yarn clamping mechanisms (37A, 37B) and/or the yarn inlet device (38) can be controlled according to the need.

Description

technical field [0001] The invention relates to a yarn splicing device for a station of a textile machine for producing cross-wound bobbins, with an air distribution body The air distribution body is equipped with a connection hole for the compressed air line, a receiving hole for holding the opening tube, and a threading prism with a threading channel to which compressed air can be applied, wherein the threading prism is spaced apart from the threading prism. A plurality of yarn handling devices are provided, such as in particular yarn cutting devices, yarn clamping devices, yarn feeders, which can be controlled via a drive. Background technique [0002] Such yarn splicing devices are known for pneumatically joining yarn ends, ie with which two yarn ends can be joined together again by means of air flow, so that almost the same joining point as the yarn occurs. Such yarn splicing devices are used in particular in stations of automatic cross-winding winders and are general...
