Description

winding machine

The invention relates to a winding machine according to the preamble of claim 1.

Winding machines serve to wind continuous filaments into coils. A generic winding machine is known from the published patent application DE 103 14 293 Al. For winding, the threads are first traversed by a traversing device transversely to the thread running direction and guided over a rotating pressure roller. The pressure roller sets the threads on each of the wound coils to be wound. Several coils are arranged in alignment one behind the other on a common winding spindle. This makes it possible to wind several threads at the same time.

The full bobbins and the empty tubes are axially removed from the winding spindles or attached to the winding spindle during an exchange. For this purpose, the winding spindles are cantilevered cantilevered. Likewise, the pressure roller and the traversing device, which together constitute a thread laying device, attached to a cantilever-shaped carrier, which is connected to the housing. In this case, the yarn laying device is substantially stationary in the sense that an increasing coil diameter is not compensated by a continuous change in the position of the yarn laying device.

Along with the steadily increasing performance of winding machines, the winding spindles are now designed for 8 or more spools, so that even for the cantilever-shaped support corresponding Bauläήgen arise, which are dynamically soft and so easy to stimulate vibrations.

BESTÄTIGUMGSKOPIE To make matters worse, that further tasks in the development of winding machines go there to connect additional units for the treatment of aufzuspulenden threads directly to the winding machine. This would additionally increase the mass that the cantilever-shaped carrier has to carry

Another weak point, which is revealed by the increasing lengths of the winding spindles, concerns the installation of the winding machine. In the customary for generic winding machines construction, the individual modules are connected to a housing which is placed by means of two parallel bar-shaped rails on the floor. It is true that the rails protrude on one side in about as far as the winding spindles, and thus also represented a static and dynamic weak point.

It is therefore the object of the invention to optimize the static and dynamic rigidity, in particular of the carrier, with regard to very long winding spindles and to additional units connected to the carrier.

According to the invention, this object is achieved by supporting the cantilevered, cantilevered, and thus dynamically and statically soft support cantilevered on both ends according to the prior art. This significantly reduces deflection and at the same time increases the permissible load.

In a preferred embodiment, the carrier on the side of the housing is rigidly connected thereto. The support on the projecting end serves the purpose of intercepting forces in the vertical direction. For this purpose, it is sufficient to perform the support as a very slim component. The slim design has the advantage that, in addition, the winding machine can be operated from the front, without the support while the operation, in particular the deporting of the full coils forward affects. Preferably, the support is supported on one and the two rails, by means of which the winder is placed from. It is known from the prior art to connect the underside of the housing with two parallel to the winding spindle rails on which the winder stands. Therefore, one of the two rails, which is located below the carrier, can serve to fasten the support.

In a preferred embodiment of the invention, it is proposed to improve the stability of the carrier in that the carrier or the housing is coupled on a drive side of the housing by a transverse support with one of the rails. This makes it possible to achieve high stability of the assembly even with small widths of the housing for supporting the carrier.

In a development of the invention, the two rails are connected to one another at the end of the collar. This can be done for example by a short crossbar, which is inserted between the rails. In a particularly preferred embodiment, a foot is provided below this crossbeam, on which the winder is placed on the ground. It has surprisingly been found that the deformations of the rails in the region of the collar end are particularly small in this design.

To set up the winding machine, the rails are advantageously supported by a total of three feet on a floor, so that a static over-determination is avoided.

A development of the invention provides a platform above the winding machine, which can be supported directly on the support, the housing or the rails. Such a platform is used to carry aggregates required for processing the thread. These can be, for example, drafting devices, turbulators or deflection rollers. This platform is understood as any attachment for such aggregates. The inventive increased rigidity of the carrier, it is now possible to provide larger and heavier units.

In a particularly advantageous development, this platform is supported by platform supports on one or both rails of the dishwasher.

In a platform arranged above the winding machine, it is advantageous if the threads are fed to the winding stations through a substantially horizontally oriented distribution system and if one or more sound absorbing means are carried by the platform above the winding stations. In particular, it is possible to dampen the noises caused by the yarn laying device. The sound absorbing means can be formed, for example, as a hood which extends above the winding machine.

According to another particular embodiment of the invention, the distributor system is formed by a plurality of low-friction movable thread guides, which are formed for example by deflection rollers for low-friction guidance of the threads. Such a distribution system is known from PCT / EP2006 / 007198 (not yet published), so that reference is made at this point to the cited document. In this case, it is possible to guide the threads around this platform or to combine the threads of the individual winding stations in such a way that they are guided as a common group of threads over the aggregates connected to the platform. For this purpose, the thread guides are provided between the winding machine and platform over which the threads are guided.

The development of the invention, in which the housing one or more sound absorbing means are associated, which extend substantially along one or both longitudinal sides of the winding machine, is particularly quiet, so that even with a variety of winding machine in a hall to achieve a relatively low noise level is. The invention will be described with reference to some exemplary embodiments in the following with reference to the accompanying drawings.

They show:

Figure 1: a first exemplary embodiment of a winding machine according to the invention in side view

Figure 2: the embodiment of FIG. 1 in front view

Figure 3: a rear view of another embodiment of the winding machine according to the invention

Figure 4: a front view of another exemplary embodiment of the winding machine according to the invention

FIG. 1 shows a side view of a first exemplary embodiment of a winding machine according to the invention. The front view of the same winding machine is shown in FIG. 2. The following description refers to both figures.

The housing 1 of the winding machine carries a rotatable turntable 9, in which two winding spindles 7.1, 7.2 are rotatably mounted with their drives. By turning the turntable 9, the winding spindles 7.1, 7.2 can each be pivoted alternately into a lower change region and into an upper winding region. Above the winding spindle 7.1 in the winding area, a pressure roller 5 is arranged. At the same time, the turntable 9 represents the means with which, as a result of the increasing coil diameter, the distance between the pressure roller 5 and the winding spindle 7.1 is increased. In the winding machine shown here four winding units 23 with four coils 6 are shown for reasons of simpler representation. This is representative of one or even a higher number of winding units. In particular, in the long-projecting winding spindles used in a winding machine according to the invention, significantly more, for example, eight or twelve winding stations are used. The winding process takes place synchronously for all winding units. Even if only one winding unit is described in the following description, this also includes other existing winding units.

From a system not shown here for producing and treating threads of the thread 10 is first fed to a more detail below to be described thread treatment device 20 and fed from there via a movable easily running yarn guide 19 of the winding unit 23.

The winding process will be described below. The tapered thread 10 is oscillated by the traversing device 4 within a traversing range, which corresponds to the length of the coil 6, parallel to the axis of the winding spindle 7.1. Subsequently, the thread is passed over the rotatably mounted pressure roller 5 and wound on the spool 6, which is mounted on the winding spindle 7.1. The winding spindle 7.2 is equipped with an empty sleeve 8 and is located in the lower change range. Once the coil 6 has reached its final diameter, the turntable 9 is rotated so that the winding spindle 7.1 is rotated in the change region and the winding spindle 7.2 in the Aufspulbereich. Also, an increasing diameter of the coil 6 is compensated by rotation of the turntable 9, so that the distance between the winding spindle 7.1 and the pressure roller 5 increases continuously. The winding machine according to the invention is not limited to this means 9 of the coil diameter compensation. Rather, other means are known from the prior art, which are covered by the invention with. The increase in the diameter of the bobbin 6 is detected by the fact that the entire consisting of pressure roller 5 and 4 Changiervorrichrang thread laying device 3 is pivotally connected to the carrier 2. By means of a control device, not shown here, the pivoting movement of the thread laying device 3 is detected and the turntable 9 further rotated in such a way that the yarn laying device 3 performs small movements, but remains essentially stationary in the course of the entire winding process. Here, too, various forms are known from the prior art to detect the increase in the coil diameter and are likewise covered by the invention.

The mechanical structure of the winding machine is structured so that the individual units of the winding machine and are supported by the housing 1. This is the carrier 2, which is cantilevered to the housing 1. On the support 2, the thread laying device 3 is pivotally mounted. The thread-laying device 3 carries the traversing device 4 and the pressure roller 5. Similarly, the turntable 9, which carries the two winding spindles 7.1 and 7.2, mounted in the housing 1. The housing 1 rests on two rails 11.1 and 11.2, which stand with the feet 12 and 14 on the floor. The rails 11.1 and 11.2 each extend parallel to the axes of the winding spindles 7.1, 7.2. On the side of the housing 1, each rail 11.1 and 11.2 has its own foot 12.1 and 12.2. On the side of the collar end 22 of the winding spindles 7.1 and 7.2, the two rails 11.1 and 11.2 are connected to a transverse bar 13. This crossbar 13 is supported centrally with the front foot 14. Through this central support an overall better distribution of the deformations of the rails 11.1 and 11.2 is achieved.

With increasing length of the winding spindles 7.1, 7.2, the mass of the traversing device 4 and the pressure roller 5 increases. At the same time, the flexibility of the carrier 2 increases. Therefore, the carrier 2 has a support 15, which supports it relative to the rear rail 11.2 on FIG. Above the carrier 2, a platform 16 is provided for receiving further units. By the support 15 of the carrier 2 in the vertical direction is sufficiently stiff to carry the mass of these additional aggregates. The connection between the carrier 2 and platform 16 takes place here by means of the rear platform supports 18. In addition, the platform 16 is supported by means of front platform supports 17 with respect to the front rail 11.1 on FIG. Also conceivable would be a support on the housing 1 or a sole support on the support 2. The platform 16 is not limited to the horizontal plate shown here. Likewise, other expedient forms for accommodating further units, for example a vertical plate, are covered by the invention.

By way of example, a thread treatment device 20 in the form of a godet 24 is shown here as an aggregate. Other embodiments of this galette, for example with an overflow roller, or other or other aggregates are possible.

In order to distribute the individual threads 10 from the thread treatment apparatus 20 to the winding units 23, a distributor system consisting of a plurality of thread guides 19 and a godet 24 is used. The yarn guides 19 are designed as deflection rollers, wherein one winding guide 23 is provided for each of the yarn guide 19. The godet 24 is held in the region of the Rragseite 22 on the platform 16, so that the threads 10 are deflected by the godet 24 in a substantially horizontally oriented distribution plane. From the distribution level, the threads pass successively to the yarn guides 19, in order to run into the individual winding units 23.

In Fig. 3, another embodiment of the winding machine according to the invention is shown in a rear view. The exemplary embodiment is embodied identically to the preceding exemplary embodiment according to FIGS. 1 and 2 in the arrangement of the assemblies, the construction of the assemblies and the function. In that regard, reference is made at this point to the above description and only explains the differences.

The turntable 9 with the projecting winding spindles 7.1 and 7.2 is rotatably mounted in the housing 1. Above the winding spindles 7.1 and 7.2, the yarn laying device 3 is held on the carrier 2. The carrier 2 is supported on the housing side 21 on the housing 1 and on the Kragseite 22 on the support 15 from. The support 15 is held by the rail 11.2. The rail 11.2 and the front rail 11.1 (not shown here) extend from the Kragseite 22 to a drive side 30 which lies on the opposite side of the housing 21 to the housing 1. On the rails 11.1 and 11.2, the housing 1 is held.

At the end formed by the rails 11.1 and 11.2 on the drive side 30, a control cabinet 28 is provided, which contains the drive and control electronics of the winding machine. For this purpose, for example, the illustrated spindle drives 29.1 and 29.2 are connected to the associated control cabinet 28 in the control cabinet. Usually, such winders on multiple drives, actuators and sensors, which are coupled to the drive and control electronics in the control cabinet 28.

For further stabilization of the machine frame of the winding machine, a transverse support 25 is connected between the carrier 2 and the rear rail 11.2 on the drive side 30. The transverse support 25 is for this purpose firmly connected to the rail 11.2 and to the carrier 2 or the housing 1. This can lead to very long projecting spindles in the case even at very high winding speeds safely.

Above the carrier 2, the platform 16 is provided, which may be formed for example by individual web-shaped carrier or plate-shaped carrier. The

Platform 16 is supported by front supports 17 and rear supports 18. The rear supports 18 are arranged between the platform 16 and the carrier 2. In contrast, the front supports 17 between the platform 16 and the front rail 11.1 (not shown here) are arranged.

Compared to the ground, the rails 11.1 and 11.2 are supported by a total of three feet 14, 12.1 and 12.2, as in the aforementioned embodiment. On the Kragseite 22, the rails 11.1 and 11.2 are connected to each other via a crossbar 13, which is supported on the foot 14. The rear feet 12.1 and 12.2 are provided in the region of the drive side.

4, another embodiment is shown in a front view. The exemplary embodiment according to FIG. 4 is identical to the exemplary embodiment according to FIGS. 1 and 2, so that at this point reference is made to the aforementioned description.

Compared to the exemplary embodiment according to FIGS. 1 and 2, the exemplary embodiment according to FIG. 4 is additionally designed with noise insulation. For this purpose, a sound absorber 26 is held on the platform 16, which extends above the yarn laying device 3 substantially over the entire winding units. On the longitudinal sides of the winding machine further sound extraction 27.1 and 27.2 are assigned in the housing 1, so that an environment acting towards encapsulation arises. The sound absorbers 26, 27.1 and 27.2 can in this case extend from the cantilever side 22 to the drive side 30. However, it is also possible for the sound absorbers 26, 27.1 and 27.2 to be of multi-part design in order, for example, to shield only individual areas above the winding machine or on the longitudinal sides of the winding machine from the surroundings. Foam walls or other sound-insulating materials can preferably be used as the sound absorber.

The exemplary embodiments of the winding machine according to the invention illustrated in FIGS. 1 to 4 are in their shape and design of the assemblies. way of example. In principle, the invention also extends to such winding machines, in which only one winding spindle is held cantilevered. In addition, the threads can also be fed in parallel vertically next to each other directly to the winding points. The combination of the carrier supported on both sides with a platform also offers the particular advantage of achieving high integration of the assemblies within a spinning device or a textile machine. This makes it possible to realize low construction heights and thus user-friendly complete systems.
