Description

The invention relates to a spin-stretch texturing machine for the production of crimped Threads according to the preamble of claim 1.

Such spin-stretch texturing machines for the production of crimped threads are generally known and are used mainly for the production of carpet yarns used. For this purpose, the spin-stretch texturing machine has one Spinning device, a stretching device, a texturing device and a Take-up device. In doing so, several threads running in parallel are made spun in a polymer melt, stretched together and side by side in parallel textured. The threads crimped after texturing will end wound up next to each other in parallel by the winding device. For this are the spinning device, the stretching device, the texturing device and the Winding device arranged vertically one below the other. Such machines However, they have the disadvantage that the threads can be laid over several floors must be performed.

A spin-stretch texturing machine is known from EP 0 718 424 A1 which the disadvantage of the bad threading possibility was eliminated, that the stretching device, the texturing device and the winding device were each combined into a machine unit to create a thread texture and wrap. Several machine units are next to each other arranged. However, this design of the stretch texturing machine has generally the disadvantage that corresponding to the parallel processing of several threads many machine units are required. Furthermore, the integration the functional modules to a machine unit disadvantageous because of mutual Influences are inevitable, for example, when changing the bobbin.

It is therefore an object of the invention to provide a spin-draw texturing machine To provide manufacture of crimped threads which is easy to use has a compact structure.

Another object of the invention is to treat and wind up to train the threads as flexibly as possible.

The task is accomplished by a spin-draw texturing machine with the features of claim 1 solved.

The invention is particularly characterized in that the facilities that to carry out the essential process steps for the production of crimped Threads are required, separated according to their function and to individual machine modules are summarized. So they form to treat the spun Threads required stretching device and texturing device together a treatment module. The treatment module is below the spinning device arranged so that the freshly spun threads immediately for treatment can enter the treatment module. After spinning and the When the threads are treated, the threads are wound into bobbins. For this is the Winding device arranged on a winding module, which is immediately adjacent the treatment module is set up and thus forms a machine longitudinal side. The texturing machine according to the invention thus has the particular advantage a low overall height, so that the stretching device and the texturing device in the treatment module and the winding device in the winding module can be operated from one level by the operating personnel. By the division of the functional groups according to the invention is a further advantage given that the bobbin changing operations in the winding device without significant influence on those arranged in the adjacent treatment module Facilities can be done.

The particularly advantageous development of the invention according to claim 2 is characterized by the fact that the narrow thread spacing to each other from the Treatment module emerging threads wound without significant spread can be. The stretching device, the texturing device and the winding device essentially form a common management level for treatment and winding the threads. This can cause thread tension differences avoided in the individual threads due to larger spreads advantageous become.

A particularly flexible design of the spin-stretch texturing machine is due to the Further development of the invention according to claim 3. For this, the floor level superposed winding units of the winding device independently driven and controlled. Every curled thread leaves individually wind up into a bobbin, taking up the winding speeds are the same. A particular advantage of this training is that Thread break in a winding unit no process interruption is required and thus a high utilization of the machine is guaranteed.

The winding units can each have a drivable winding spindle Have recording of the coil. For a continuous winding of the threads to ensure, the winding units could each have two drivable winding spindles for alternately holding the coil.

In the manufacture of crimped threads are made after spinning the threads Depending on the type of yarn, additional treatments may be required. So will for example when using stuffer box texturing devices additional cooling device used to cool the thread plug. As well could improve a swirling of the threads before or after texturing a thread closure may be required. Because of the particularly advantageous Further development of the invention according to claim 6 is given the possibility to integrate additional treatment facilities in the treatment module.

To ensure that there is no malfunction in the take-up device Process interruption occurs is according to a preferred development of the invention the winding device is assigned a suction device, which Suction device for each winding unit one upstream suction nozzle having. This is a continuous withdrawal of the threads from the treatment module guaranteed even if the thread breaks in one of the winding units.

The particularly advantageous developments of the invention according to claim 8 and 9 are characterized by a very high degree of automation. It is a robot for thread guidance when threading at the beginning of the process and a doffer is provided for changing the bobbins in the winding units. The The robot or the doffer is preferably movable on the longitudinal side of the machine guided so that a thread guide from the spinning device to the winding device is possible.

The embodiment variant of the invention is characterized by high operational reliability. Likewise, volatile constituents are removed during of the company, such as, for example, relationship fog, is advantageously shielded.

The Components with the same functions have been given identical reference symbols. The Structure of the embodiment is essentially identical to the previous one Embodiment. In this respect, only the differences are shown below explained and otherwise reference to the preceding description of the figures 1 and 2 taken.

The treatment module 6 and the winding module are below the spinning device 1 10 set up side by side on a machine longitudinal side. The treatment module 6 contains a preparation device arranged one after the other in the thread running direction 9, a deflection roller 12.1, a delivery unit 30, a stretching device 11, a texturing device 14, a cooling device 31, two delivery units 16.1 and 16.2 and a swirling device 32, which is between the delivery plants 16.1 and 16.2 is arranged. Compared to the previous embodiment in this embodiment, the threads 7 by an additional Delivery unit 30 withdrawn from the spinning device 1 and to the following Stretching device 11 out. The stretching device is made up of two godet units 13.1 and 13.2 formed, each containing two driven godets. The threads 4 are parallel to each other with several wraps led around the respective godet units 13.1 and 13.2. Here are the godet units 13.1 and 13.2 driven at differential speed, so that the Threads are drawn. After stretching, a compression crimp occurs within the texturing device 14. For this purpose, the texturing device 14 a texturing nozzle 39. The texturing nozzle 39 is a cooling device 31 subordinate to the circumference side by side per thread a circumferential groove to the thread plugs 35 emerging from the texturing device 14 take. The cooling device 31 is designed as a drum on its circumference the thread plugs 35 are cooled. To loosen the thread plugs 35 are the threads 7 by the downstream delivery unit 16.1 of the cooling device 31 deducted. Between the delivery plants 16.1 and 16.2 is one Swirling device 32 arranged on the treatment module 6. in this connection the threads are swirled to produce an increased thread closure. This completes the treatment of the threads. The threads become Run winding module 10 and on the individual winding units 17.1, 17.2 and 17.3 distributed the winding device 15. The winding units 17 have here each have a spindle carrier 18 with a winding spindle 37 on the circumference of a driven contact roller 19 are held. The spindle carrier 18 are pivoted. In the thread run in front of the contact roller 19 is one Traversing device 20 is provided, which preferably by a thread guide 46 an overflow thread running out takes over and essentially parallel leads to the coil 41 back and forth.

The winding device 15 is assigned a suction device 33, which has several Has suction port 34. Here, each winding unit 17.1 to 17.3 is one assigned to the suction port 34. The suction device 33 is with a yarn container (not shown here) connected. In the event of a bobbin change or in the event that a thread break occurs in one of the winding units 17.1 to 17.3, becomes the incoming thread over the respectively assigned suction port 34 the suction device 33 and fed to a yarn container. Thereby it is ensured that the treatment facilities in the treatment module 6 can continue to be operated without interference. Switching off the Process is not required.

In the spin-draw texturing machine shown in Fig. 3 is on the side of the winding module 10, an operating aisle is formed in which the doffer 26 is guided is. The doffer 26 is identical to the previous embodiment and takes over the bobbin change in the winding units 17.1 until March 17th

For placing the threads 7 in the treatment devices of the treatment module 6, the robot 22 is movably guided parallel to the longitudinal side of the machine. The Robot 22 is identical to the previous embodiment, so that reference is made to the previous description.

The embodiments shown in Figures 1 to 3 are in structure and Arrangement of the treatment devices and the winding device as an example. For example, all the necessary components in the thread entry area as well as godets, texturing units, cooling drum, tangling in a clear Be arranged in the treatment module 6. Through the lateral arrangement of the winding device in the winding module results a very compact arrangement with a height that can be less than 2 m. This makes the treatment facilities simple and easy to use as well as the rewinder.

Individual treatment devices can also be removed from the treatment module removed or replaced, for example uncrimped FDY yarns or to produce POY yarns.

In the stretching devices shown in the exemplary embodiments, the number is and the execution of the godets is basically freely selectable. The design the stretching device depends on the manufacturing process and the whole type.

The number of threads which are guided and treated in parallel is also shown three threads) exemplary. So single threads or multiple threads can be without Managing, handling and winding up problems. Could wind up the threads the winding units are also formed, for example, by two winding stations, which can be used alternately to wind up the thread. By the single thread Thread guidance in the winding area results on each winding unit same run conditions. It is therefore a gentle and even winding the threads guaranteed. The winding units can be dependent on the number of threads both vertically one above the other and horizontally arrange next to each other.

Robots and doffers can be used advantageously for automation. in this connection could, for example, use a robot for threading only for Treatment facilities of the treatment module 6 to be responsible. Such one Robot is able to perform all necessary movements and mooring processes perform. The treatment facilities of the treatment module could do this such as the preparation device, the texturing device and the swirling device corresponding auxiliary devices exhibit. A second robot could thread the threads in the take-up reel and change the bobbin.
