Description

Technical field
BACKGROUND OF THE INVENTION The invention relates to a device for handling a yarn end at a spinning station of an annular spinning machine after locating a yarn end on a bobbin, comprising a suction tube with a suction mouth assignable to a spinning station. guiding the suction pipe orifice to the stretching device of the spinning station to resume the spinning process.
The invention also relates to a method of handling a yarn end by a device according to the invention at a spinning station of an annular spinning machine after locating the yarn end on the bobbin and sucking the yarn end into the suction tube mouth. process.
The invention also relates to an annular spinning machine comprising a plurality of spinning stations, each having a prestretch device, and the machine having a service device arranged reciprocably movable along the row of spinning stations, the service device being provided with a yarn end handling device according to the invention.
BACKGROUND OF THE INVENTION
The annular spinning machines comprise a plurality of juxtaposed spinning stations, each of which comprises a yarn draw-through device, from which the treated fiber yarn is fed to a twisting device from which the yarn produced is removed and wound in a winding device onto a sleeve mounted on a rotating spindle. thereby forming a bobbin or a bob, i.e., a yarn winding tube. If the yarn production is interrupted, for example as a result of a rupture, the yarn production at a particular spinning station needs to be resumed. When the spinning process is renewed at the spinning station, where after spinning is interrupted, for example, the feed rollers of the yarn into the draw-through mechanism are stopped, or the draw-through mechanism is running and the fibers from the yarn are sucked into waste, etc. usually records the runner's motion sensor. It is then necessary to locate the end of the wound yarn on the spool, unwind the yarn, gradually thread it through the runner, the balloon restrictor and the guide loop, and finally bring the yarn end between the yarn end rollers so that the yarn end joins with the end of the yarn, thereby preparing a spinning station to resume yarn production. All of these service operations are performed with the continuous vertical reciprocating movement of the annular bench and balloon restraint carrier, since other spinning sites continue to produce yarn. Various handling devices are used to handle the yarn end, from its retrieval on the spool to its passing to the spinning station means, for example according to EP 391 110 or US 3,540,200 and others. In essence, these are spatial yarn end manipulators that perform general movement in space.
There is very little space at the spinning station of the annular spinning machine because the spacing of the spinning stations is, for example, only 70 or 75 mm, so that the size and mobility requirements of a possible handling device are considerably limiting. At the same time, great demands are placed on the reliability and simplicity of the manipulator.
It is an object of the present invention to provide a reliable and simple yarn end manipulator, i.e. a yarn end handling device after it has been found on a spool on an annular spinning machine, both reliable and simple in terms of design, operation and minimal impact on the yarn handling properties.

The invention will be described, by way of example, of a yarn end handling device at a spinning station of an annular spinning machine.
The annular spinning machine comprises a plurality of identical spinning locations arranged side by side. The spinning station is in principle well known and will therefore be described here as a whole in a simplified manner. The parts, elements, and nodes of the spinning site that are relevant to the present invention will be described in more detail. The spinning station comprises a yarn draw-off device (not shown) under which a yarn twisting and winding device is arranged. From the not shown master spool, the yarn is fed into the draw-through mechanism, behind which the already-formed yarn passes successively through the guide eye, the balloon restrictor and then by the runner which circulates around the periphery of the ring flange. The yarn produced is wound into a coil 4 on a tube 1 which is slid onto a vertical spindle which rotates about its vertical longitudinal axis. The yarn winding 4 on the tube 1 forms a spool, with the winding 4 on the tube 1
By providing a reciprocating vertical linear movement of the annular bench 2 in conjunction with the yarn winding device after passing the yarn through an unseen runner that orbits the spool 1 along the ring flange 3, the lag is formed by twisting the runner beyond the spindle speed. the yarn turns into a yarn of desired properties wound on a spool. The spindle is usually driven in its lower part by a flat belt driven by a drive shaft.
Along the row of spinning stations, a service device is displaceably arranged, which comprises mechanisms and means for carrying out individual service operations at the spinning station, respectively. for carrying out at least some service operations at a spinning station, wherein the serving operations serve to bring the spinning station into operation in which the yarn is produced. The keypad is able to stop at the selected spinning station.
