Embodiment Construction

[0029] exist figure 1 A textile machine for the production of cross-wound bobbins, in the present embodiment an automatic cross-winder, is shown schematically in side view, generally designated with the reference number 1 .

[0030]As is known, such automatic cross-winders have, between their end frames (not shown), similar workstations, in this example winding heads 2 . At these winders 2, the worsted bobbins 9 produced on a ring spinning machine (not shown) are rewound to form large rolls of cross-wound bobbins 15, which are passed through Robotic service units (also not shown) are conveyed to a cross-wound bobbin transport mechanism 21 along the length of the machine.

[0031] In this embodiment, the automatic cross-winding machine 1 also has a logistics mechanism in the form of a bobbin / bobbin delivery system 3 specific to the machine. Worsted cops 9 or empty bobbins positioned in a vertical orientation on a transport plate 8 circulate in this bobbin / bobbin transport sy...

Abstract

The invention relates to a thread splicing device comprising a splicing prism with a splicing channel, to which pneumatic pressure can be applied, in addition to a control element that can be driven by an individual motor. At least one thread tensioning and cutting unit for fixing and severing the thread ends that are to be spliced and a thread feed for positioning the prepared thread ends in thesplicing channel are connected to the control element by means of actuating elements. According to the invention, the control element consists of a pivotally mounted control element (18) comprising external gearing (19), which meshes with a drive pinion (20) of an individual drive (22) that can be controlled in a defined manner and the actuating elements (47, 44) for the thread tensioning and cutting unit (23) and the thread feed (26) are rotationally fixed to the control segment (18).

Description

technical field [0001] The invention relates to a thread splicing device. Background technique [0002] Yarn splicing devices have been known for a long time in the textile machine industry, especially in relation to automatic cross-winders. [0003] Such a yarn splicing device, which has proven successful in practice, is described in detail in DE 42 40 728 A1, or in the Schlafhorst Winding Systems brochure "Autoconer 338". [0004] Two ends of thread can be pneumatically twisted by this yarn splicing device, creating a knot-free connection that actually has the strength of yarn and ideally has almost the same appearance as yarn. In other words, when a yarn break occurs at one of the winders of an automatic cross-winder during the winding process, or when a scheduled clearing is performed at one of the winders of a textile machine due to a yarn defect When cutting with a splicing machine, the thread end of the disconnected yarn is first brought back to the area of ​​the ya...
