Description

The invention relates to a method of a textile machine, in particular a spinning or winding machine with a plurality of similar jobs, for supplying a thread to a coil, for laying the thread on the spool, for winding the thread on the spool and for finding a on the Coil wound thread end by means of a suction nozzle, wherein the thread end is sucked by means of the coil circumference facing serving as Ansaugmündung the suction nozzle opening, and a corresponding textile machine with a yarn feeder, a Fadenchangiereinrichtung, a winding device and a suction nozzle with a Ansaugmündung.

From the EP 1 283 288 A2 For example, a spinning device of an open-end rotor spinning machine is known. A thread is spun in an open-end spinning device and delivered to a winding device. For defined laying of the supplied thread on a spool, a single motor driven Fadenchangiereinrichtung is provided. After a thread break the resulting thread end is wound onto the spool. In order to use this end of the thread to re-start with a new thread, it must be searched on the spool. For this purpose, a pivotally mounted, unterdruckbeaufschlagbare suction nozzle is provided. The suction nozzle pivots in the event of a yarn breakage from a lower position up to the coil circumference of the coil and insufflates it. The coil is set in a rotational movement, so that after a certain time, the thread end is detected and sucked by the suction nozzle. Subsequently, further manipulations take place in order to use the thread end for the restart. For this purpose, the thread end is transferred from the suction nozzle to other devices. This procedure is time-consuming, since the suction nozzle must first be set in motion and the end of the thread found by appropriate movements to the other handling equipment must pass. In addition, the structural complexity and the required space are significant.

From the EP 0 128 121 A1 a fixed suction nozzle is known, which is associated with a coil on a winder. If the thread breaks or before the thread of a new supply spool is applied to the thread end of the thread spooled on the spool, the spool is stopped. Subsequently, it is rotated in the direction opposite to the winding direction to unwind a sufficiently long for the piecing end of the thread from the bobbin. In order for the end generally strongly adherent to the coil surface to be found and detached, a suction source is turned on and negative pressure built up in the suction nozzle which propagates through the mouth to the coil surface. The vacuum draws in air from the environment through the gap between the orifice lips of the nozzle. The thread end attracted by the coil surface through the negative pressure prevailing there is now caught, entrained and pulled away by the strong flow inside the nozzle. The disadvantage here is also that the found thread end removed from the nozzle, prepared for piecing and must be brought back into the normal threadline. This known device is time-consuming in operation and therefore disadvantageous for the efficiency of the machine.

From the EP 2 444 347 A2 a winder is known which guides the thread in a thread guide channel between the supply reel positioned in Abspulstellung and the winding device and completely surrounds it. After the guide channel, a pivotable suction head is provided, with which a thread end detected on the spool and can be spanned between the coil and the mouth of the suction head. For further handling of the thread this must be returned to other handling equipment. In the yarn guide various Fadenüberwachungs- and thread handling devices are arranged. Through the long, stationary Thread guide channel, the cleaning in the case of a blockage through the thread, be very expensive.

Object of the present invention is thus to provide a method and an apparatus with which a thread end can be found both quickly and quickly and easily with a new thread, so that the production of the thread can be continued with only a short break.

The object is solved with the features of the independent claims.

The inventive method on a textile machine, in particular a spinning or winding machine with a plurality of similar jobs, is used to supply a thread to a coil, for laying the thread on the spool, for winding the thread on the spool and finding one on the spool wound thread end by means of a suction nozzle. The thread end is sucked by means of a coil circumference facing, serving as the suction port of the suction nozzle opening. In order to find the thread end quickly on a spool at a breakage of the thread and to have him quickly available for a new thread, it is provided that the thread during delivery to the spool, that is during the normal production of Thread, through the suction nozzle is running. The thread enters through a further, serving as the inlet opening for the thread opening into the suction nozzle and through another opening, in particular through the intake, again from the suction nozzle. Starting from a thread supply device, which may be a spinning station or a cop of a winder, the thread first runs free and only immediately before the bobbin does it enter the suction nozzle. The fact that the thread is in the suction nozzle during the normal delivery process immediately before the coil, he must not be taken out of the suction nozzle when piecing after a yarn breakage and finding the thread end, placed in a different threadline and recurs, but may remain after finding the thread end in the suction nozzle and in the yarn path. This saves time when re-attaching the thread to a new thread. The productivity of the machine and its efficiency can be increased thereby. Characterized in that the thread from the yarn feeder first free, ie not running through the suction nozzle and enters only immediately before the coil in the suction nozzle, the handling of the yarn is very simple. For example, withdrawal means of the thread for removal from the delivery point can be easily operated thereby. The threading of the thread in the suction nozzle can be done easily, since no long paths of the thread in the closed suction nozzle must be covered. Clogging of the suction nozzle is thus reliably avoided. The suction nozzle is thus relatively short. A yarn path with a length of less than 80 cm, preferably less than 40 cm within the suction nozzle has been found to be particularly advantageous.

In addition, the structure of the working according to this method textile machine is much simpler than in the prior art, since handling equipment, which must remove the thread end of the suction nozzle and spend in the normal yarn path, not or at least not required to a considerable extent.

Particularly preferably, the thread runs during normal delivery to the coil both through the inlet mouth and through the suction port of the suction nozzle. As a result, the thread can be guided after the suction opposite to the direction of delivery in the intake port and the inlet port and moved after the attachment of the thread back in the normal delivery direction, without changing the position significantly.

In a particularly advantageous embodiment of the invention, the suction nozzle either via the inlet mouth or a third, as a connection mouth serving opening connected to an extraction system. The extraction system generates negative pressure in the suction nozzle and thereby causes the negative pressure applied to the suction opening to find the thread end on the circumference of the coil when the coil, in particular against the normal winding direction, moves along the suction opening. The connection of the suction nozzle with the suction system offers itself particularly well over the already existing inlet mouth. In another embodiment of the invention, it may also be advantageous that a third opening is arranged on the suction nozzle, which is connected to the suction system. At this point, the extraction system can be permanently connected and there must be no movement of the negative pressure leading components.

If the inlet mouth for sealing the suction nozzle is closed during suction of the thread end, the negative pressure at the suction opening is increased in a particularly advantageous manner. Suction losses via the inlet mouth are thus avoided.

If the inlet mouth when sucking the thread end connected via a connecting element with the suction, so in this embodiment of the invention, the essential, negative pressure leading component is fixedly arranged in the machine. Only the connecting element has to be moved. This can be done quickly and without major construction effort.

If the suction opening of the suction nozzle is adjusted in at least two, preferably three positions with different distances to the circumference of the coil, it is possible to optimally discuss different states. In particular, it can be used to the special requirements in the normal delivery operation of the thread, the thread or used in a need for special handling of the thread, for example, for lifting the thread from a traversing yarn guide. Due to the different positions of the intake port with respect to the coil circumference can be a very fast Locate the thread end and handle the thread end to be carried out for restarting.

It when the movement of the adjustable Ansaugmündung is coupled with a thread lifter and / or with a yarn guide the Fadenchangiereinrichtung is particularly advantageous. This coupling can be done mechanically or by means of an electronic control. The coupling may be such that at a certain position of the intake port of the thread lifter lifts the thread from the thread guide so that it no longer shimmers on the surface of the coil and / or that the thread guide the Fadenchangiereinrichtung is caused to emerge from the Area of the coil or the Ansaugmündung moved out so as not to be in the way of the movement of the intake port.

It is particularly advantageous if the intake orifice is arranged in the first, in particular the middle, position of the intake orifice, when the yarn is wound onto it during normal delivery to the bobbin. In this first position, the suction port is positioned so that it does not interfere with the threadline. It is neither too close to the spool, where it could hinder the winding of the thread on the spool, nor is it pulled back too far to hinder the threadline in the suction nozzle.

In the second, in particular closer position of the intake port, the thread end on the spool is searched through the intake port. The suction port is thus in the immediate vicinity of the coil circumference and can exert a particularly high suction force on the surface of the coil here.

If the second position of the intake opening is set as a function of the coil diameter and / or the thread to be received, then the thread end can be found and picked up very quickly and safely.

In the third, in particular more distant position of the intake port, a thread lifter is actuated. The thread lifter causes the thread is lifted out of the Fadenchangiereinrichtung or kept out. The thread guide can be moved in this position out of the region of the suction mouth, so as not to hinder the handling of the thread. This position is particularly advantageous when the thread is in the suction nozzle, but should not be changed.

A textile machine according to the invention, in particular a spinning or winding machine with a plurality of similar jobs, each, ie per job, a yarn feeder for supplying a thread to a coil, a Fadenchangiereinrichtung for laying the thread on the spool, a winding device for winding the yarn on the spool and a suction nozzle for finding a wound on the spool thread end. In addition, the suction nozzle has an opening facing the coil circumference and serving as an intake opening for sucking the yarn end. The suction nozzle may be stationary or movable. Preferably, however, it is fixed stationary at the workplace. According to the invention, the suction nozzle has, in addition to the suction orifice, a further opening serving as the inlet opening for the thread, wherein the thread runs through the suction nozzle during delivery to the bobbin. The thread enters through the inlet mouth into the suction nozzle and through another opening, in particular the suction port, from the suction nozzle again. The suction nozzle thus has at least two different orifices through which the thread passes during the delivery to the coil. Thus, the difference of the threadline in the normal delivery compared to the position of the thread when finding the thread end and its suction into the suction nozzle is not or only slightly different. The handling of the thread end for use in re-attaching the thread to a new thread is therefore particularly easy to perform. The handling of the thread can be done very quickly and easily. The construction costs can be kept low. For the handling of the thread, it is particularly advantageous if the suction nozzle is arranged only immediately in front of the spool, so that the thread first runs freely from the thread supply device and only enters the suction nozzle immediately before the spool. A threadline with a length of less than 80 cm, preferably less than 40 cm within the suction nozzle has been found to be particularly advantageous to prevent clogging of the suction nozzle and leave enough space, for example, the thread withdrawal device or a thread connecting device manually or to operate with appropriate handling facilities.

It is particularly advantageous if the suction nozzle is arranged stationarily at the workstation. As a result, a movement of the suction nozzle itself is not required. The structure of the suction nozzle and the attachment to the job can be done very easily.

Advantageously, the suction nozzle is designed such that a connection via the inlet mouth or a third, serving as a connection mouth opening can be made to an exhaust system. When connecting the extraction system to the inlet mouth, the construction effort is very low. However, in such an embodiment there is a risk that the installation space which is available at this point is small, so that the arrangement of the connection of the suction nozzle with the suction system at this point can be problematic. Easier is the arrangement of the suction via a third, serving as a connection mouth opening at the suction nozzle. This opening can be arranged in a region of the suction nozzle to which more space is available. Hereby, the execution of this variant of the invention can be carried out easily.

In a preferred embodiment of the invention, the inlet mouth is assigned a closure element. The closure element serves for sealing the suction nozzle when sucking the thread end. This embodiment, which will be provided in particular in conjunction with a third, serving as a connection mouth opening to a suction, serves to ensure that the negative pressure at the intake is high and not by further, not needed at this moment openings, is weakened. Locating the thread end with a high negative pressure at the intake port is usually faster and more reliable than with a low vacuum.

If the inlet opening is assigned a connecting element for connecting the suction nozzle to the suction system during suction of the thread end, both the suction nozzle and the suction system and the corresponding suction pipe connections can be arranged stationarily at the workstation. Through the connecting element, the suction nozzle can be connected to the negative pressure of the suction system.

Preferably, the connecting element and or the closure element for the inlet opening is pivotally mounted or displaceable. The connection of the suction nozzle with the suction system or the closing of the inlet orifice which is not required at this moment can thereby be carried out very simply.

If the suction opening of the suction nozzle is adjustable, in particular displaceable, the suction opening can be brought into different positions with respect to the coil circumference of the coil. As a result, a negative pressure can be selectively generated on the surface of the coil or the suction port can be moved from a disturbing for the thread end area.

If the adjustable intake muzzle is coupled to a thread lifter and / or to a thread guide of the thread switching, a movement of the thread lifter or the thread guide can be effected by the movement of the suction muzzle. In particular, the coupling of Ansaugmündung and thread lifter can be done by means of a slotted guide. Due to the movement of the intake mouth of the thread lifter is guided along this backdrop and can perform appropriate movements, in particular lift or lower the thread from the thread guide.

The yarn guide of the Fadenchangiereinrichtung can be moved out of the region of the intake at a corresponding position of the intake port. This is preferably done by means of an electronic circuit which causes in a certain state of the machine that the thread guide is moved out of the critical area. This is particularly advantageous if the thread-changing device and / or the winding device have individual drives. Through these individual drives, the individual workstation, regardless of the other jobs perform a certain, currently required movement of Fadenchangiereinrichtung or the winding device.

In FIG. 1 a workstation 1 with a spinning unit 2, a yarn feeding device 3, a suction nozzle 4, a Fadenchangiereinrichtung 5 and a winding device 6 is shown. In the spinning unit 2, a thread 7 is produced and withdrawn by means of delivery rollers 8 from the spinning unit 2. The thread 7 then passes, after it has been released to this point, immediately before a coil 12 of the winding device 6 through an inlet opening 9 in the suction nozzle 4 and exits the suction port 10 back out of this. Of the arranged between the suction port 10 of the suction nozzle 4 and the winding device 6 Fadenchangiereinrichtung 5, the yarn 7 is wound by means of a reciprocating yarn guide 11 on the spool 12. The spool 12 rotates in the direction of the arrow in order to be able to wind up the thread 7. The coil 12 is held in a Spularm 14 and driven by a rotating winding roller 13. Characterized in that the thread 7 runs freely over a long distance, it can be easily inserted when applying the thread 7 between the feed rollers 8 or introduced into the spinning unit 2.

In the area of the inlet opening 9, a connection mouth 15 of a suction line 16 is arranged. The suction line 16 is connected to an exhaust system 17, in which negative pressure prevails. The suction line 16 is by means a valve 18 shut off, so that only when necessary negative pressure at the connection port 15 of the suction line 16 is applied.

The suction nozzle 4 with the inlet opening 9 and the suction line 16 with the connection mouth 15 are designed separately from each other. While the yarn 7 is being delivered to the spool 12, the yarn 7 passes the mouth 15 and passes into the inlet mouth 9 into the suction nozzle 4. A connecting element 19, which is able to connect the inlet mouth 9 with the connection mouth 15, is arranged offset laterally to the yarn path, so that the yarn 7 is not obstructed.

In FIG. 2 is the job of the FIG. 1 shown. In contrast to the representation of the FIG. 1 is at FIG. 2 the yarn 7 is returned from the spool 12. The thread 7 was previously interrupted, so that the thread end was wound on the spool 12. In order to be able to find and receive the thread 7 or its thread end on the surface of the spool 12, the suction orifice 10 of the suction nozzle 4 is evacuated. The suction takes place in such a way that the connecting element 19 connects the inlet mouth 9 with the connection mouth 15. When the valve 18 is opened, negative pressure from the suction system 17 therefore prevails in the suction nozzle 4 via the suction line 16. The connecting element 19 thus creates a continuous suction channel which consists of the suction nozzle 4, the connecting element 19 and the suction line 16. The thread 7 is sucked after finding on the circumference of the coil 12 in this suction and can then be further treated. A treatment can be, for example, that the thread 7 cut to length and the resulting end of the thread for re-spinning in the spinning unit 2 is prepared.

By removing the connecting element 19 and thus reopening the suction nozzle 4, the end of the thread clamped by the negative pressure can be detected by an operator or a handling device and removed from the channel for further treatment.

FIG. 3 shows another job 1, which similar to the job 1 of FIG. 1 is. Unlike the execution of the FIG. 1 However, this has a suction nozzle 4, which has three openings. In addition to the inlet opening 9 and the intake port 10, the connection port 15 is integrated in the suction nozzle 4. A connection of the inlet mouth 9 and the connection mouth 15 as at FIG. 1 is therefore not required. In the normal course of the thread - upon delivery of the thread 7 - the thread 7, as also described above, enters the suction nozzle 4 through the inlet opening 9 and leaves it again through the suction opening 10 before it is wound on the spool 12 rotating in the direction of the arrow , The inlet opening 9 is associated with a closure element 28. Upon delivery of the thread 7, the closure element 28 is outside of the threadline, so as not to disturb it. The suction line 16 may be shut off.

In FIG. 4 is analogous to FIG. 2 at a job 1 according to FIG. 3 the return delivery of the thread 7 and the thread end shown. The spool 12 rotates in the direction of the arrow opposite to the winding direction. The thread end was previously detected by the suction port 10 of the suction nozzle 4 and sucked by the negative pressure of the suction system 17 with the valve 18 open. In order to generate the highest possible negative pressure at the intake opening 10, the inlet opening 9 is shut off by means of the closure element 28. The thread 7 is thus located in a substantially closed suction channel, which is formed from the suction nozzle 4, the closure element 28 and the suction line 16. The connection orifice 15 is part of the suction nozzle 4.

In FIG. 5 the suction nozzle 4 is shown with the intake port 10 in detail. Between the suction port 10 and the spool 12 and the winding roller 13, which drives the spool 12, the yarn guide 11 of the thread switching device 5 is arranged. The yarn guide 11 moves the yarn 7 before the coil 12 back and forth, so that a cheese is formed. Below the thread 7, between the intake port 10 and the yarn guide 11, a thread lifter 20 is arranged. The thread 7 runs in this illustration, which shows the delivery of the thread 7, over the thread lifter 20 away.

The thread 7 is detected in the suction nozzle 4 by a sensor 22. This sensor 22 may be active, for example during the normal yarn delivery. It is more advantageous, however, when the sensor 22 is used to detect whether the thread 7 has been detected by the suction nozzle 4 when returning from the coil 12.

At the suction port 10, the thread 7 exits from the suction nozzle 4. The suction port 10 is arranged in a mouthpiece 21, which is located in the suction nozzle 4. It may also be arranged wholly or partially outside the suction nozzle 4. The mouthpiece 21 is slidably mounted in the suction nozzle 4. The displacement takes place substantially in the thread longitudinal direction, so that the mouth piece 21 can be brought closer or closer to the spool 12.

With the mouthpiece 21 is, as in FIG. 6 illustrated, the thread lifter 20 coupled. In FIG. 6 is the mouthpiece 21 compared to FIG. 4 further away from the coil 12. It is thus further inserted into the suction nozzle 4. The mouthpiece 21 or the suction orifice 10 is thus located in a second position, which is farther away from the spool 12 than in the first position of the spool 12 FIG. 5 ,

By the second position of the mouthpiece 21 and the Ansaugmündung 10 of the thread lifter 20 has been moved to a raised position. The thread lifter 20 engages in this position under the thread 7 and lifts it out of the thread guide 11 out. The yarn guide 11 is thus no longer able to change the yarn 7 back and forth. This position is advantageous when the thread 7 is in the suction nozzle 4, but a winding on the spool 12 is not intended. This can, for example, bring advantages in the event of a controlled delivery stop of the thread 7. Another situation in which this position of the thread 7 outside of the thread guide 11 is desired, for example, when Wiederanspinnen the previously interrupted thread. 7

In FIG. 7 a third position of the intake port 10 is shown. In this position, the intake port 10 is very close to the surface of the spool 12. The mouthpiece 21 is almost completely extended from the suction nozzle 4. The thread lifter 20 is in a lower position so that the mouthpiece 21 can be moved across it. In order to avoid a collision with the yarn guide 11, the yarn guide 11 has been moved out of the region of the mouth piece 21 by means of the thread-changing device 5. The yarn guide 11 is accordingly laterally of the mouth piece 21. By the application of the suction nozzle 4 with negative pressure according to the embodiments of the FIGS. 1 to 4 is negative pressure at the intake port 10, which sucks a located on the circumference of the coil 12 yarn end. The spool 12 rotates in the direction of the arrow counter to the delivery direction and thus promotes the thread end into the suction nozzle 4. The sensor 22 detects whether the thread end is located in the suction nozzle 4 and can accordingly stop the suction or initiate further handling steps.

In the Figures 8a, 8b and 8c is shown a link 23 for the thread lifter 20 in the three positions described above. The gate 23 is connected to the mouthpiece 21 and is moved together with the mouthpiece 21 in the longitudinal direction. It has a slotted guide 24, in which a sliding block 25 slides. The thread lifter 20 is connected via a linkage 26 with a rotation axis 27 and the sliding block 25. By moving the link 23 in the longitudinal direction of the sliding block 25 is moved in the slotted guide 24 and raises or lowers the thread lifter 20 according to or from.

In the presentation of the FIG. 8a the thread lifter 20 is in a middle position. Accordingly, the gate 23 is in a middle position, which is the representation of FIG. 5 with the corresponding mouthpiece 21 corresponds.

If the mouth piece 21 together with the link 23 in the remote position according to FIG. 6 or 8b moves, so the slide guide 24 causes the sliding block 25 is guided downward. As a result, lifts the thread 20 to in accordance with FIG. 6 to lift out the thread 7 from the thread guide 11.

In FIG. 8c is the front position of the gate 23 and the mouthpiece 21 from FIG. 7 shown. In this position, the sliding block 25 is located at the other end of the slotted guide 24. About the axis of rotation 27 of the thread lifter 20 is moved to a lower position so that it releases the path for the mouth piece 21 and the mouth piece 21 in the front, close to the coil position can be moved.

The present invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims are also possible as a combination of features, even if they are shown and described in different embodiments.
