Description

The present invention relates to a textile machine with a plurality of jobs according to the preamble of claim 1.

In textile machinery textile machines that have a variety of identical jobs, long known in various embodiments and relatively extensively described in numerous patents.

Such textile machines, which are often also known as multi-point textile machines, are, for example, rotor spinning machines, texturing machines, flyers, ring spinning machines, double-twisting machines or cabling machines, etc.

Such multi-point textile machines often have at least one extending in the longitudinal direction of the textile machine, usually continuous drive shaft, are connected to the thread processing devices, which are for example, cantilevered.

Double twisting machines or cabling machines have, for example, a large number of such identically designed work stations, which are arranged on both sides of the machine longitudinal axis next to one another and are each equipped, inter alia, with a winding device for creating a cross-wound bobbin.

The winding device usually has a friction roller for the frictional drive of a cross-wound bobbin and a yarn processing device upstream of the friction roller in the form of a so-called advancing roller, by which the thread tension of the thread running on the cross-wound bobbin is adjusted, that is, as a rule is reduced ,

The magnitude of the reduction of the thread tension is determined by the wrap angle of the thread around the advance roller and by the peripheral speed of the advance roller in relation to the winding speed of the cross-wound bobbin.

This means in practice that the cheese driven by the friction roller rotates at a much lower rotational speed than the leading roller.

With regard to the drive of the friction rollers and the advance rollers, various embodiments are prior art in connection with such double-twisting or cabling machines.

By the DE 34 03 144 A1 , the DE 42 17 360 C2 or the DE 100 45 909 A1 For example, double twisting or cabling machines are known in which both the friction rollers and the leading rollers of a textile machine side are each driven by separate, machine-length drive shafts. In these known double twisting machines or cabling machines, in particular the machine-length drive shafts lying in the working range of the operating personnel have proved to be of little advantage for the advance rolls, both in terms of safety technology and in terms of operation.

That is, to prevent accidents such machine-length drive shafts are usually, such as in the DE 100 45 909 A1 shown, provided with a cover or a cover, the panel is equipped only at the jobs with narrow slits. In machine-length drive shafts, however, the interruption of the yarn path, caused, for example, by the tearing of the yarn during reeling, often causes the problem that the yarn is caught by the further-rotating drive shaft and wound up on it.

The operator then often tends to expose the drive shaft or the lead roller by removing the cover, thus improving the accessibility to the resulting winding.

However, such an approach is extremely dangerous, since the drive shaft continues to rotate at undiminished speed.

A disadvantage of such machine-length drive shafts is the poor interchangeability of yarn-transporting components. Changing a leading role is relatively expensive, for example. In the past, therefore, it has already been proposed to dispense with machine-length drive shafts, at least for the advance rollers and instead to drive the advance rollers on the already existing drive shafts for the friction rollers.

The DE 10 2005 050 074 A1 describes a double twisting or cabling machine in which the leading rollers of the numerous jobs are each stored individually on special support elements, which make it possible to pivot the lead rollers between an operating position and an operating position.

The advance rollers are also connected in each case via an endless traction means to one of the two machine-long friction shafts, wherein the endless traction means on the one hand comprises a arranged on one of the machine-long friction shafts drive element and on the other hand is mounted on a non-rotatably connected to the advance pulley output means. In practice, however, the known per se arrangement of Endloszugmittels has not proved to be particularly advantageous. That is, in these two-for-one twisting or cabling machines, replacement of the "trapped" by a machine-length friction shaft, as a round belt, if necessary, takes place Trained endless traction means always as relatively difficult and time-consuming, which has, since during the change process usually at least one machine side of the Doppeldrahtzwirn- or cabling machine must be shut down, has a negative effect on the efficiency of the textile machine.

By the DE 10 2006 061 289 A1 Furthermore, double twisting machines or cabling machines are known, in which the advance rollers are each connected via a magnetic gear to a drive shaft, preferably to the friction shaft of one of the two textile machine sides.

Such magnetic transmissions are relatively insensitive to contamination and have the advantage of high reliability.

In contrast to form-fitting torque transmission devices, in such magnetic transmissions, for example, the exceeding of a limit torque when an unforeseen operating condition occurs immediately stops the associated leading role.

However, a serious disadvantage of this advantageous magnetic transmission is in its relatively complex production, which means that such magnetic gear, especially in relation to the endless traction means described above, are quite expensive.

Based on the aforementioned prior art, the present invention seeks to develop a multi-point textile machine, which does not have the disadvantages described above, but still has a reliable and cost-effective drive for their numerous, each arranged in the field of jobs Fadenbearbeitungseinrichtungen.

This object is achieved by a textile machine having the features described in claim 1.

Further advantageous embodiments of the invention are the subject of the dependent claims.

In particular, the embodiment according to the invention has the advantage that the endless traction means can be exchanged simply and easily if necessary.

That is, the drive means of the drive shaft each have two coaxially arranged deflection and guide grooves, wherein one of the deflection and guide is part of a freely rotatably mounted idler gear.

When winding the endless draw means this can first be inserted by means of a loop in the rear guide groove connected to a cantilevered thread processing means driven means and then pulled around the associated, fixed to the drive shaft drive means that two adjacent strands of Endloszugmittels arranged the two coaxial with the drive shaft Include deflection and guide grooves of the drive device.

The remaining loop of the endless drawing means can then be inserted with a rotation through 180 ° in the guide groove positioned at the free end of the drive means of the thread processing device.

As set forth in claim 2, it is also provided in an advantageous embodiment that the deflection and guide grooves of the drive means, in which the two strands of the endless draw means are guided, are arranged adjacent and parallel. By such an arrangement of the deflection and guide grooves acting on the endless traction means during operation Walk and bending forces can be minimized, which has a very positive effect on the life of the respective endless traction. According to claim 3 is further provided that the drive device preferably with respect to the drive shaft rotatably mounted rotary body with a deflection and guide groove for the driven strand of Endloszugmittels and a respect to the drive shaft rotatably mounted rotary body with a deflection and guide groove for the opposite direction of drive having continuous strand of Endloszugmittels.

That is, the deflection and guide grooves are arranged and formed in rotational bodies of the drive means so that a proper running of the endless drawing means is always ensured.

In an advantageous embodiment, which is described in claim 4, it is provided that the drive device is designed as a pulley element, with a rotatably fixed to the drive shaft main body and a freely rotatably mounted on the main body loose wheel.

The main body is equipped with a deflection and guide groove for the driven strand of Endloszugmittels, while the idler gear has a deflection and guide groove for the opposite strand of Endloszugmittels.

Such a design of the drive device not only ensures a safe drive of arranged in the field of jobs of the textile machine thread processing equipment, but overall a long life of the drive device.

According to claim 5 is provided in an advantageous embodiment that per machine side of the textile machine in each case a drive shaft is arranged, which is equipped with a plurality of the take-up reels driving friction rollers, wherein the drive means are formed by deflecting and guiding grooves integrated into the friction rollers for the strand of the endless drawing means to be driven and adjacently arranged pulley arrangements.

That is, the pulley devices each have a loose wheel with a deflection and guide groove for the opposite strand of the endless drawing means.

Such a design not only allows a very compact training a job, which is easily ensured that the spindle distance of the textile machine can be minimized, but it also keeps the design effort for the drive devices within limits.

As set forth in claim 6, it is also provided in an advantageous embodiment that the idler gear is freely rotatably connected to the main body via a bearing.

A rolling bearing (Anspr.7) is the optimal solution for the intended use, since such bearings are not only proven, cost-effective mass-produced components that cope with higher speeds easily, but such bearings also represent components that are characterized by a long life ,

In an alternative embodiment, however, a plain bearing may also be used as the bearing, as described in claim 8. Also, such sliding bearings are proven, low-maintenance machine parts.

As described in claim 9, it is provided in a further embodiment that as a drive shaft for the yarn processing devices a machine-length, preferably Machine-end-driven, central mother shaft is used.

At least one drive device, which in turn is connected via an endless traction device and an associated output device to a yarn processing device, is fixed to this mother shaft in the area of the work stations, wherein the endless traction devices are alternately guided to both machine sides.

About such a central mother shaft are easy to drive the thread processing facilities both sides of a textile machine machine simultaneously.

When using such a mother shaft is not only, as described in claim 14, easily adjustable over different intersections of Endloszugmittel the direction of the yarn processing devices of the two textile machine pages, but also, as set forth in claim 15, on the speed of the central mother shaft easily a central adjustment the working speed of the connected thread processing equipment possible.

If these thread processing devices, as known, for example, from double twisting or cabling machines and designed in claim 11, are designed as advance rolls, a central adjustment of the so-called advance factor of the numerous advance rolls can be realized in a simple manner.

As set forth in claim 10, it is furthermore provided in an advantageous embodiment that round belts are used as endless draw means, the length of the round belt being more than four times the distance between the center axis of the drive device and the center axis of the driven means.

Such round belts are in mechanical engineering for a long time proven endless traction means that, since they are standard mass production parts, are commercially available affordably.

In addition, such round belts, especially when the endless traction means must be installed in the crossed state, have proven many times in practice as a safe drive means.

That is, such round belts represent safe and cost-effective fasteners.

The yarn processing devices described many times above, like the textile machines, can be designed very differently.

In connection with double twisting machines or cabling machines, the thread processing devices may, for example, as described in claim 11, be designed as advance rolls, which are preferably, as known, cantilevered.

In connection with such overhung Voreilrollen the output means, which are wrapped by Endloszugmittel, each mounted on well-accessible bearing shafts so that, if necessary, both the endless traction means and the output means is easily replaceable.

That is, in this type of storage all rotating parts in the area of the leading role can be stopped temporarily without any problems during a necessary intervention, which also simplifies the handling of the advance role by existing, relatively large space and thus the risk of injury is minimized.

As a thread processing facilities, which are driven by a present invention installed endless traction means can However, instead of advance rolls, other thread processing devices are also used.

It is also quite possible, for example, as described in claim 12, via a drive shaft of a textile machine, which is equipped with drive means for guiding and carrying along endless traction means and corresponding endless traction means to drive godets. The preferably also cantilevered godets are provided on their bearing axis in each case with a driven means.

Another possible use for a drive device according to the invention is, for example, also in the drive of paraffining devices, as they are known from various textile machines forth (claim 13).

Such paraffining devices can also be advantageously driven by means of drive devices arranged on a machine-long drive shaft, which are encompassed by endless draw means installed according to the invention and act on driven means connected to the paraffining devices.

Regardless of the particular type of thread processing device, the inventive design and arrangement of arranged on a machine-length drive shaft drive means in conjunction with corresponding output means in the field of thread processing equipment and inventively applied endless draw means always allows a reliable and cost-effective drive such Fadenbearbeitungseinrichtungen.

The Fig. 1 schematically shows a side view of a multi-point textile machine, in the embodiment, a Doppeldrahtzwirn- or cabling 1.

As is known, such textile machines have a plurality of work stations 2, which are arranged side by side on both sides of the machine longitudinal axis.

The workstations 2 of such double-twisting or cabling machines 1 are each equipped inter alia with a double-twisting device 3 and with a winding device 4.

In the in the Fig.1 illustrated embodiment, a deducted from a double wire spindle 5 thread 6 runs over a thread guide 7, which limits during twisting a resulting in the twisting device 3 thread balloon 8 in height, the winding device 4, where the yarn 6 is wound into a cheese 10.

The winding device 4 has, as usual, a creel 12 for rotatably holding the cross-wound bobbin 10, wherein the creel 12 can be raised by means of a pneumatic cylinder 18 in case of need.

Furthermore, the winding device 4 has a fixed on a continuous friction shaft 14 friction roller 13 for rotating the cheese 10 in the direction of rotation R and a Fadenchangiereinrichtung 11 for traversing the running thread. 6

In the thread running direction F before the Fadenchangiereinrichtung 11 is a thread processing device 41, in the exemplary embodiment, a lead roller 9, arranged on a wound according to the invention Endloszugmittel 19 to a machine-length drive shaft, in the embodiment of Fig.1 to a friction shaft 14 of the relevant machine side of the multi-point textile machine 1, is connected.

Furthermore, a thread feeler 15 is arranged between the thread guide 7 and the advance roller 9, which monitors the proper running of the thread 6 during the twisting process.

The yarn feeler 15, which is connected via a signal line 16 to a control device 17, detects yarn breaks occurring during the twisting operation and reports these in each case immediately to the control device 17, which then initiates via the control line 21 a pressurization of the associated pneumatic cylinder 18 with pressure.

That is, when a yarn break occurs, the creel 12 is pivoted upwardly and thereby the cross-wound bobbin 10 is lifted from the rotating friction roller 13. After the thread breakage, the creel 12 is lowered again, so that the cross-wound bobbin 10 again rests on the friction roller 13 and can be rotated by the latter again frictionally in the direction R.

Like in the Fig. 1 schematically illustrated, are on the machine-length, acting as drive shafts friction shafts 14 drive means 20 are fixed, which are each connected via a specially arranged Endloszugmittel 19 and an associated output means 22 to one of the yarn processing means 41, in the embodiment of advance rolls 9.

In the case of double-twisting or cabling machines, the advance rollers 9 serve to reduce the thread tension of the thread 6 to be inflated, which, after cabling or twisting, has a thread tension, the so-called balloon tension, which lies above the thread tension that is justifiable for constructing a cross-wound bobbin 10.

To reduce this too high yarn tension, the advance roller 9, which is at least partially wrapped by the yarn 6, driven at a peripheral speed which is greater than the yarn speed of the running on the cheese 10 thread 6. In this way it is achieved that the balloon tension Reason the relative to the thread speed higher peripheral speed of the leading roller 9 and the degree of wrap of the thread 6 is reduced by the advance roller 9 until a tenable for the construction of a proper cross-wound bobbin thread tension is present.

As in particular from the Fig.2 it can be seen, the advance roller 9 is preferably arranged in each case axially parallel to the friction shaft 14 on a carrier 23.

To simplify the assembly and disassembly of the advance roller 9, an overhung bearing of the advance roller 9 is provided in an advantageous embodiment.

On the bearing shaft 25 of the overhung Voreilrolle 9 is a driven means 22 rotatably installed, which, as from Fig. 6 can be seen, two adjacently arranged deflection and guide grooves 26A, 26B for two strands of Endloszugmittels 19 and a suitable shaft / hub connection, for example, a threaded bore 27 for a clamping screw or the like. For fixing the output means 22 on the bearing shaft 25 has.

All embodiments have a base body 28, which by means of a threaded bore 29 and a clamping screw or the like. Non-rotatably mounted on the friction shaft 14 can be fixed.

As in Fig. 5A illustrated, the main body 28 is provided in a first embodiment with a deflection and guide groove 30 for the driven strand of Endloszugmittels 19 and with a bearing lug 31 for a bearing 32, which is preferably designed as a rolling bearing or sliding bearings. In the present embodiment, a so-called idler gear 33 is mounted on the outer ring of a rolling bearing 32, which has a deflection and guide groove 34 for a running opposite to the drive direction of the yarn processing device 41 second strand of the same endless drawing means 19.

When in the FIG.5B illustrated second embodiment of a drive device 20, the deflection and guide groove 30 is integrated into the friction roller 13 for the driven strand of Endloszugmittels 19.

Close to the friction roller 13, a base body 28 is rotatably fixed on the friction shaft 14, which has a bearing 32, for example, a roller bearing or a plain bearing.

As of the embodiment according to 5A known, a so-called idler gear 33 is fixed on the outer ring of the rolling bearing 32, which has a deflection and guide groove 34 for the counter-rotating second strand of the endless drawing means 19.

Subsequently, the endless traction means 19 is pulled around the fixed to the machine-length friction shaft 14 drive means 20 so that two adjacent strands of Endloszugmittels 19 include the drive means 20, for example, in the 5A illustrated embodiment.

That is, with respect to the friction roller 13 rear strand of the endless drawing means 19 is inserted into the deflection and guide groove 34 of a rotatably mounted on the main body 28 of the drive member 20 idler gear 33, while the front strand of the endless drawing means 19 in the Riemenaufnahmenut 30 of the main body 28th the drive device 20 is positioned.

Following the two strands of Endloszugmittels 19 are rotated by 180 ° about their common longitudinal axis and inserted in this state in the front receiving groove 26A of the output means 22.

In the in the Figures 2 As well as 5A shown embodiment, the drive device 20 is each completely formed as a separate pulley device 40 which is spaced apart next to the friction roller 13 mounted on the friction shaft 14. That is, the pulley device 40 has a base body 28 with a deflection and guide groove 30, a bearing 32 and a loose wheel 33 with a deflection and guide 34 and is rotatably with its base body 28 via a shaft / hub connection, for example on a Drive shaft 35 acting friction shaft 14 set.

In an alternative, in the Figures 3 and 5B illustrated embodiment, the drive device 20 is partially integrated into the friction roller 13. That is, the friction roller 13 has a deflection and guide groove 30, in which the strand to be driven in the drive direction AR of the endless drawing means 19 is inserted.

Immediately adjacent to the friction roller 13, a pulley device 40 is additionally arranged on the friction shaft 14, on the main body 28 of which a idler gear 33 is preferably rotatably supported via a rolling bearing 32, in whose deflection and guide groove 34 the second strand of the endless drawing means 19 is supported. that it can rotate counter to the drive direction AR of the thread processing device 41.

The Figure 4 shows an embodiment in which as a drive shaft 35 instead of the arranged on the machine sides A and B of the multi-point textile machine 1 friction shafts 14, a central, machine-length nut shaft is used.

As already explained above in connection with the friction shafts 14 designed as drive shafts 35, a multiplicity of drive devices 20 are also fixed on this central drive shaft 35, each of which has an endless traction means 19 are connected to a driven means 22 of a yarn processing device 41, also in the present embodiment, a leading roller 9.
