Abstract

The invention relates to a device for winding up several bunches of threads with two winding machines that are disposed next to each other in a mirror-inverted manner. Each of said winding machines comprises several mechanical and electrical subunits for winding a bunch of threads onto several bobbins, the winding machines being embodied so as to be separately driven and controlled. In order to obtain a high degree of integration of the winding machines in spite of a separate mode of operation, the winding machines are configured differently regarding the structure and arrangement of the subunits thereof regardless of the mirror symmetry while the function of the subunits in the respective winding machines remains unchanged.

Description

Multiple Thread Winding Device {DEVICE FOR WINDING UP SEVERAL BUNCHES OF THREADS}

The present invention relates to a device for winding a plurality of yarns, which comprises two winding machines arranged next to each other in mirror plane symmetry according to the preamble of claim 1.

In the manufacture of artificial yarns, there is an increasing tendency for multiple yarns to be spun simultaneously simultaneously next to each other in parallel from the polymer melt in the spinning position and subsequently to failure. Therefore, it is known to radiate 10, 12, 16 or more yarns in parallel and to wind them simultaneously in failure. In this case, the thread winding can be carried out by a winding machine, where the failure is fixed and wound on the winding spindle. This type of winding machine, coupled with more wide failures and many threads, requires a correspondingly long winding spindle. Accordingly, a new concept is provided where multiple threads are divided into separate thread bundles, failures corresponding to one thread bundle are wound on the first winding spindle, and failures corresponding to another thread bundle are wound on the second winding spindle in parallel. Developed.

DE 100 45 473 A1 and JP 2000-177927 A disclose a device in which two winding machines are arranged next to each other in mirror symmetry. A thread bundle is fed to each winding machine to wind the thread of the thread bundle into failure. To this end, the winding machines are placed next to each other, in parallel on the longitudinal side of the device, forming a mirror plane symmetry plane between them. In this case, the winding machines are constructed in the same form, where the construction and arrangement of the mechanical and electrical subcomponents are mirror symmetric. The two winding machines can be operated independently of one another. Because of the mirror symmetry in known devices, two types of winding machines, each costing the same manufacturing cost, must always be provided. Therefore, each winding machine has mechanical and electrical subassemblies that include the same fasteners and housing claddings.

However, devices for winding a large number of thread bundles are known from WO 03/068648 A1, in which the lower parts of the two winding machines are integrated into one machine. In this case, the subcomponents can only be operated together, for example only one thread bundle cannot be separated for winding. In addition, these types of devices have disadvantages because of their size and weight, because in many spinning plants, regular maintenance must be carried out on a separate winding machine, for which the winding machine has to change the spinning position. .

It is an object of the present invention to develop a general type of device having two winding devices arranged next to each other in mirror symmetry, which, despite the fact that the winding machine is a separate mode of operation, integrates the sub-components to produce the device. To reduce the

This object is achieved in accordance with the present invention, in which the winding machines are configured differently regardless of the mirror symmetry in the construction and arrangement of their sub-parts, and the function of the sub-parts in each winding machine is maintained.

Advantageous refinements of the invention may be made by the features of the dependent claims and the combination of the features.

The present invention applies a completely new method of operating two winding machines in one apparatus. Therefore, the two winding machines are no longer identical in their subparts. Thus, for example, the lower parts can be moved or combined without changing the function of the winding machine. Therefore, the two winding machines can be driven and controlled separately, as before. A particular advantage of the present invention is that a novel design free configuration is provided which has considerable potential for cost reduction and optimization of the operating sequence. In addition, the device according to the invention is particularly suitable for winding a large number of yarn bundles in a spinning position by allowing the winding machine to be configured in a very compact form.

According to a particularly preferred refinement of the invention, at least one sub-part assigned to one of the winding machines is assigned to the other winding machine. Thus, for example, one of the winding machines may be of a basic type that includes only the sub-components necessary for winding the thread bundle. The opposite winding machine, in addition to the basic type, contains all the other additional sub-components that allow the two winding machines to be fully functional.

For example, an improvement in which electrical sub-components, such as drive electronics and control, are arranged and coupled to one of the winding machines is particularly desirable in this case. Therefore, all sensitive components can be coated together to protect the spinning plant from environmental influences and prevent defects.

In particular, however, in yarn fishing devices, mechanical subassemblies, if possible, can also be combined to be fixed to one of the machine supports by means of common fastening means.

Mechanical sub-parts, in particular winding spindles used in the winding machine, have to be changed regularly in the winding machine since there may be a certain maintenance interval. In this case, it is particularly preferred that the machine feet consist of two feet which are detachably connected to each other. Therefore, the winding machines can be exchanged independently of each other and can be combined with other winding machines. Thus, the work for changing the winding machine is made quite easy.

In this case, it is particularly preferred that the central control unit is detachably connected to the winding machine. Therefore, the electrical subassemblies and mechanical subassemblies of the winding machine can be combined into a unit of interchangeable structure.

The device according to the invention is described in more detail below by means of several exemplary embodiments with reference to the accompanying drawings.

Is more (2). The right winder 1 is arranged on the machine base 6. 1 and the left winder 2 on the machine base 6. 2. The machine supports 6.1 and 6.2 are detachably connected to each other by a plurality of connecting means 7.

In Fig. 3, the left winder 2, shown in side view, is provided with mechanical subassemblies which are explained in more detail below. A winding turret 3.2 is rotatably mounted and fixed to the machine support 6. 2. This winding turret (3.2) is connected to a rotary drive (23.2). Two elongated winding spindles 4.2 and 5.2 are rotatably mounted to the winding turret 3.2 of the left winder 2. The first winding spindle 4.2 is connected to the spindle drive 21.2 and is located in the winding area in the illustrated operating state. The circumference of the winding spindle is tensioned on a number of tubes 8, on which a plurality of threads 20.1-20.4 of the first thread bundle 20 are wound on the failure 9. The second winding spindle 5.2 is offset by 180 ° relative to the first winding spindle 4.2 and is fixed to the winding turret 3.2 and is located in the replacement area. The second winding spindle 5.2 has a number of tubes 8 at its circumference.

In a real arrangement, there is a pressing roller 11.2 and a traversing device 13.2 prior to the winding spindles 4.2 and 5.2 of the left winder 2. The pressure roller 11.2 originally lies over the entire length of the winding spindles 4.2 and 5.2 and is rotatably fixed to the roller rocker 12.2 at its end. The roller rocker 12.2 is pivotally attached to the machine support part 6.2.

The traversing device 13.2 has a laying unit at each winding position, whereby each yarn is placed back and forth in the transverse stroke of the winding position. In this embodiment, the traversing device 13.2 consists of a vane type traversing device, for example as known from EP 0 771 302. For a more detailed description of this type of traverse, see the above publication.

In this case, the sub-parts mentioned above constitute a left winder 2 which is one of the basic types of winding machines. In contrast, the right winder 1 comprises the same subparts and also additional subparts which function in both the right winder 1 and the left winder 2. In this case, the configuration of the rightward winder 1 is basically the same as that of the leftward winder 2. In this case, the individual subparts of the leftward winder 2 are attached to the machine support 6. 2 in mirror plane symmetry with respect to the subparts of the rightward winder 1. Therefore, the description of the basic type of the right winder 1 refers to the preceding description of the left winder 2, and only further sub-parts are described below.

Above the machine support 6. 1 of the right winder 1, shown in side view in FIG. 2, electrical subassemblies in the form of a controller 14 and a drive electronics 28 are arranged in combination. The control device 14 and drive electronics 28 are connected to the drive and actuator of the rotary drive 23.1, the spindle drive 21.1 and 22.1 and the right winder 1, which are no longer shown in detail. And also to the drive and actuator of the rotary drive 23.2, the spindle drive 21.2 and 22.2 and the left winder 2, which are no longer shown in detail. As such, the control device 14 and the drive electronics 28 constitute a central control unit for the two winding machines.

Above the rightward winder 1, further mechanical subassemblies are provided to guide the thread bundle while the thread bundles 19 and 20 move to the winding machines 1 and 2. For this purpose, a thread guide strip 16 is arranged in the carrier 15. The thread guide strip 16 has a first thread guide group 17 and a second thread guide group 18 parallel to the winding spindles of the right winder 1 and the left winder 2; have. The first thread guide group 17 is composed of a total of four thread guides 17.1 to 17.4 assigned to the threads 19.1 to 19.4 of the first thread bundle 19. Each thread guide 17.1 to 17.4 is located in front of the traversing device 13.1 of the right winder 1 and constitutes the thread entry in the individual winding position and thus the end of each cross triangle.

The 2nd thread guide part group 18 is comprised from the thread guide parts 18.1-18.4 assigned to the yarns 20.1-20.4 of the 2nd thread bundle 20. As shown in FIG. To this end, the longer protruding thread guides 18.1 to 18.4 are fixed to the thread guide strip 16, so that the thread guides 18.1 to 18.4 are adapted to guide the second thread bundle 20. 2 room moving It is fixed to the plane. In this case the thread guides 18.1 to 18.4 constitute the seal entry in the winding position of the left winder 2 and are located in front of the traversing device 13.2. The thread guides 18.1 to 18.4 thus constitute the starting point of each transverse triangle of the winding position.

As shown in FIG. 4, the first yarn guide group 17 and the second yarn guide group 18 are movably fixed to the yarn guide strip 16. To this end, in each case, these two thread guide groups assigned to the corresponding winding positions of the right winder 1 and the left winder 2 are attached to each sliding shoe 24. It is arranged. Therefore, the thread guides 17.1 and 18.1 are fixed to the sliding shoe 24.1, and the thread guides 17.2 and 18.2 are fixed to the sliding shoe 24.2 (and so on). The sliding shoe 24 is arranged in the linear guide 25 and can be guided back and forth in the linear guide by the linear drive 26. In this case, the sliding shoes 24.1 to 24.2 can be connected to one another, for example via a cable pull assembly. The linear drive 26 can be driven by a control mechanism 27 integrated into the control device 14. Since the thread guide groups 17 and 18 are driven by the linear drive 26, they can be guided back and forth between the phishing position, the catching position and the operating position. In this case, the phishing position of the thread guide groups 17 and 18 is selected when the phishing of the yarn is required at the start of the process or after the thread cutting. The catching position is selected when the seal must be caught in the catching slots of the tube at the start of the winding operation.

In order to fish the threads of the thread bundles 19 and 20 to the tubes 8 of the winding spindles 4.1 and 4.2 of the two winding machines, an additional sub-part in the form of a fishing device 29 is the right winder 1 Is placed on. Phishing device 29 is shown in its stop position in FIGS. 1, 2 and 3 and in its operating position in FIG. 5 for phishing thread bundles.

For the first phishing of the thread bundles 19 and 20, the right winder 1 and the left winder 2 have a yarn fishing arm 31.1 and a yarn fishing arm of the fishing device 29. (32.2) is assigned. The thread fishing arms 31.1 and 31.2 are pivotally fixed to the machine support 6. 1 of the rightward winder 1. For this purpose, the thread-fishing arms 31.1 and 31.2 are connected together at one end to the pivot shaft 35. Thread guide members are provided at opposite ends of the thread fishing arms 31.1 and 31.2 to bias the thread bundle 19 and the thread bundle 20 independently of one another. The pivot shaft 35 is fixed to the holder 30 attached to the machine support 6.1 of the right winder 1. The thread fishing arms 31.1 and 31.2 are connected to a common push drive 32. The push drive device 32 is connected to the thread fishing arm 31.1 via the first push member 33.1 and to the thread fishing arm 31.2 via the second push member 33.2. In order to drive the phishing device 29, the push drive device 32 is connected to the control device 14. In this case, the thread fishing arms 31.1 and 31.2 of the fishing device 29 can be guided from the stop position to the operating position at the same time. The operating position of the seal fishing arms 31.1 and 31.2 is shown in FIG. 5. In this state, during the first fishing, the yarn of the thread bundle 19 is supplied to the tube 8 and the winding spindle 4.1. In this case, under the thread guide strip 16, a right lifter 1 is arranged with a seal lifter 34.1 and a left winder 2 with a seal lifter 34.2. The seal is prevented from entering the traversing devices 13.1 and 13.2 by the seal lifter, and positioning to the respective winding position is performed.

As soon as the thread bundle is connected to the respective tubes 8 of the winding spindles 4.1 and 5.1, the winding of the thread starts and the thread phishing arms 31.1 and 31.2 return to their stop positions.

The mode of operation of the individual winding machines is known and disclosed for example in EP 0 374 536 A1. To illustrate its function, reference is made to the cited publication. Stroke sensors 36.1 and 36.2 are assigned to roller rockers 12.1 and 12.2, respectively. The stroke sensor 36.1 of the right winder 1 and the stroke sensor 36.2 of the left winder 2 are connected to the controller 14. The rotary drives 23.1 of the winding turret 3.1 and the rotary drives 23.2 of the winding turret 3.2 are respectively controlled such that the pressure rollers 11.1 and 11.2 maintain their original predetermined positions during the winding of the failure 9. To do this, in the controller 14, the sensor signal is converted into a control signal via the drive electronics 28.

The continuous intermittent movement of the winding turrets 3.1 and 3.2 takes place in the opposite direction in this case, so that the shifting movement of failure, which continues to increase in magnitude, in the case of the right winder 1, It is carried out clockwise with the rotation of the winding turret 3.1 and in the case of the left winder 2, it is carried out counterclockwise with the rotation of the winding turret 3.2. Thus, the minimum distance between the right winder 1 and the left winder 2 is determined. Therefore, the winding turrets 3.1 and 3.2 are arranged at a distance not more than twice the diameter of the failure already wound on each other, and preferably less than twice the diameter of the failure already wound.

6 is a side view of another embodiment of a device according to the invention. The embodiment according to FIG. 6 is the same as the previous embodiment in the construction and arrangement of the mechanical sub-components of the winding machine, so that reference is made to FIGS. 1 to 5 and only the differences are described below.

In the exemplary embodiment shown in FIG. 6, the electrical subassemblies of the winding machines 1 and 2 are coupled to the central control unit 36. The central control unit 36 is fixed to the support 6.3 of the machine support on the drive side of the winding machines 1 and 2, respectively. In this case, the central control unit 36 is connected to the right winder 1 via a plug connection 37.1 and to the left winder 2 via a plug connection 37.2. In the drives, actuators and sensors of the winding machines 1 and 2 all supply control and signal lines are provided by plug connections 37.1 and 37.2. Each of the supporting parts 6.1, 6.2 and 6.3 is detachably connected to each other so that it is possible to exchange the winding machines 1 and 2 independently in the central control unit 36. Therefore, the supporting parts 6.1 and 6.2 are connected to the supporting part 6.3 by simple plugging means as shown by the dotted lines.

Exemplary embodiments of the apparatus shown in FIGS. 1 to 6 are examples of the construction and arrangement of subcomponents. In general, the right winder and the left winder can be combined in the drive such that the winding turrets are driven and operated together, for example, via a common drive. The illustrated subcomponents are also illustrative. The subcomponents can also be configured such that thread bundles are also caught in accordance with the principle of synchronization. In this case, thread deflection and thread guiding are performed by sub-parts, such that the direction of thread movement and the direction of rotation of the tube are the same during the first phishing of the thread and the catching of the thread.
