Description

The invention relates to a texturing machine for crimping threads according to The preamble of claim 1 and a method for applying a running thread to a delivery mechanism with two cantilevered rotatably mounted Rolls in a texturing machine.

A generic texturing machine is known from DE 36 23 370.

Such texturing machines are used, on the one hand from a smooth thermoplastic multifilament yarn a curled bulked yarn and on the other hand to stretch the thread so that the crimped Yarn has sufficient strength for further processing strength. To the For example, delivery mechanisms are used, each having a conveyor roller with an associated overflow roller on which the thread is guided with several wraps This can be produce particularly high stretching forces. On the other hand, require such Delivery works before an executable by an operator landing procedure Start of the process to allow the multiple wrapping of the thread. there must be ensured that the incoming thread and the expiring thread in separated levels to an entanglement of the adjacent To avoid thread pieces on the circumference of the rolls when creating.

EP 0 591 825 discloses a Strucktexturierspulmaschine in which a thread using a manually guided Absangpistole is created. JP-A-60015361 discloses a method for hooking a thread, in which the thread with help a role is created.

Accordingly, it is an object of the invention, a texturing machine of the beginning so-called type in such a way that the thread before the trial independently from an operator with great certainty and reproducible to the Delivery works with a conveyor roller and an overrun roller can be applied

This object is achieved by a texturing machine with the Features according to claim 1 and by a method for applying a Thread to a delivery mechanism with the features of claim 13 solved.

In the texturing machine according to the invention the rollers is a Mooring device assigned by which a thread before the beginning of the process The circumference of the rollers can be applied with a total wrap of> 360 °. Of the particular advantage of the texturing machine according to the invention is that to Beginning of the process - the thread largely automatically without intervention of a Operator can be guided. By activating the docking device the thread could be taken over directly and created at the delivery plant or the already laterally guided next to the rollers thread could be detected and to the Delivery plant to be created. After applying the thread in preferably several wraps, the docking device is disabled and in a Resting position brought.

In an advantageous development of the texturing machine according to the invention the application device has at least one movable thread guide and a guide means controlling the movement of the thread guide. This will be a secure picking, grasping or guiding of the thread throughout Application process possible. The guide means, for example, by form electrical or pneumatic means that controlled a uniform Allow movement of the thread guide.

The thread guide is advantageous by the guide means in one Management plane transverse to the longitudinal axes of the rollers on one of the rollers at least teilumhüllenden guideway is guided in the wrapping direction. This ensures on the one hand that the thread in a running plane is applied evenly to the circumference of the rollers and on the other hand the Movement of the thread is supportive in the application process. Of the Thread guide is moved on a guideway, the two in Spaced apart rollers according to the Wrapped wrapping direction. Here, both guide means To be used, the thread guide on a closed guideway lead around the rollers, or such guide means, the thread guide on a non-closed guideway by a forward and backward movement to lead.

To capture a thread run alongside the reels before the start of the process and to put on, the thread guide is preferably formed as a wire bow. Of the Wire bracket is connected at one end to the guide means, so that the Wire bracket can be guided, for example, by pivoting movements.

A preferred development of the texturing machine according to the invention sees before that the wire hanger when moving on its guideway a catch position passes through, in the area of the running of the rollers thread, here as Drain side is called, is arranged. The wire hanger will be out of the Catching led to a landing position, which is in the area of the Rolls of incoming thread, which is referred to as inlet side is located. In order to can the side of the rollers running thread regardless of the Mooring device be made free before applying. Only when activating the Anlegevorrichtung the thread is caught by the thread guide and created. Due to the particularly preferred developments of the invention Texturing machine with a wire hanger as thread guide is the further advantage given that the thread only by the movement of a single thread guide can be applied. For this purpose, the wire hanger on a fishing groove, the movement of the Wire clip in the catch position the thread passing through the management level catches and at the transition to the docking the the wireframe tapered Thread piece on the circumference of the rollers applies. To prevent that from the wire hanger running thread piece is applied to the periphery of the rollers, is provided a sliding edge extending from the management level to the free Front ends of the rollers extends. This ensures that the transition from the inlet side to the outlet side running from the thread guide Thread piece outside the Rollenumschlingung is performed.

According to another particularly advantageous embodiment of the invention Texturing machine, the thread guide can also be through a Injektorrohrstück form, which is traversed by the thread and which by a carrier with is connected to the guide means. This allows the application process still extend so that the thread after applying to the rollers through the Mooring device to a next processing unit or a next Delivery plant is performed.

For controlling the movement of the yarn guide, the guide means according to an advantageous development of a trained in the machine frame Sliding track and guided in the slide track on sliding shoe. It will the guideway of the thread guide determined by the shape of the slide track. The yarn guide is preferably firmly connected to the shoe. Of the Sliding shoe is coupled with a drive, which is used to activate the Binding process is controllable.

However, it is also possible that the yarn guide by means of a pivot arm, the is pivotable about an axis of rotation, is guided. For this purpose, the axis of rotation preferably arranged between the rollers on the machine frame. The Movement of the swivel arm is by one on the machine frame arranged pivoting drive controlled.

To create the thread even in hard to reach areas of the machine to be able to make is, according to an advantageous embodiment of Texturing provided according to the invention, the thread by means of several Guide tubes with connected injectors. This is up the inlet side of the rollers a blowing end of one of the guide tubes and on the Drain side arranged a suction of another guide tube. Especially in false twist texturing, it is known the thread over such Guide tubes automatically in a post-treatment zone until winding threading. In that regard, this advantageous development is particularly for False twist texturing machines suitable.

To ensure that when creating the thread that of the thread guide running thread piece does not come into the range of Rollenumschlingung is the blowing end of one of the guide tubes around the suction end of the other Guide tube laterally adjacent to the rollers arranged such that a Threadline forms, one of the front ends of the rollers spanned Level permeates. Here, the bubble end is in the area of the roll wrap and the absorbent disposed outside the area of the roll wrap.

By the method according to the invention it is ensured that even during the Applying several wraps no entanglement of the thread pieces is possible because the thread guide on the inlet side of the rollers and the Thread guide on the discharge side of the rollers in their positions during the Investing remain unchanged. For this purpose, the thread before the beginning of the Application process from the inlet side laterally next to the rollers to the led opposite drain side of the rollers. Now the thread is on the Drain side by one in the threadline in the direction of the rollers moved Thread guide caught and fed by the thread guide on a guideway The wrap around the distance to the rollers led to the inlet side. at Movement of the thread guide is thereby the the thread guide tapered Thread piece applied to the circumference of the rollers and running from the thread Thread piece outside the Rollenumschlingung out. Once the thread guide has reached the thread running plane on the inlet side, the thread is from the Thread guide released. The yarn guide tapered piece of thread wraps around the rollers and now runs from the circumference of the inlet side arranged roll to the opposite outlet side.

To create several wraps of thread on the rollers, the Repeat the process several times according to the number of wraps.

The inventive method is not limited to delivery plants in the field of Texturing limited but can also easily Use delivery systems or drafting systems in other areas in which two spaced-apart rollers with one or more threads with lead several wraps.

The rollers 16 and 17 of the delivery mechanism 14 are cantilevered on a Machine frame 25 stored. The conveyor roller 16 is in this case with a Roller drive 26 connected.

The application device 15 has a movable yarn guide 27 and a with the guide 27 connected to the yarn guide 29. The guide means 29 is in this case by a pivot drive 30, a rotation axis 31 and a Swivel arm 32 formed. The pivot arm 32 is at the free end with a Thread guide 27 forming wire hanger 44 firmly connected. The wire bow 44 forms a catching groove 33 and a sliding edge 34 on the catch groove 33rd opposite side of the wire bracket 44 is formed. The wire bow 44 is guided by the guide means 29 on a guide track 37, which the Rollers 16 and 17 encloses (Figure 2). In this case, the catching groove 33 of the moves Wire bracket 44 in a transverse to the longitudinal axes of the rollers 16 and 17 itself extending guide plane 28 (Figure 3). The management level 28 is located in Wrap around the rollers 16 and 17. The on the wire hanger 44th formed sliding edge 34 extends from the guide plane 28 in a Area outside the roll wrap, which through the front ends of the Rollers 16 and 17 spanned plane is penetrated by the sliding edge 34.

To apply the thread 24 to the periphery of the rollers 16 and 17, the thread 24 first between the guide tubes 12 and 18 in the free run of the Inlet side 35 to the outlet side 36 of the delivery mechanism 14 laterally next to the rollers 16 and 17 led. The case between the guide tubes 12 and 18 spanned Threadline penetrates the guide plane 28 in the region of the discharge side 36. In This phase begins the application process by activating the Applier.

In Figures 2 and 3, the application process by a plurality of positions of Wiring bow 44 illustrated At the beginning of the investment process, the wire hanger brought by the guide means 29 in a catch position. This is the thread 24 caught by the catch groove 33 of the wire bracket 44 on the drain side 36. The Position of the wire bracket 44 in this situation is in the figures 2 and 3 with I characterized. As the movement of the wire hanger 44 progresses, that of the guide tube 12 to the wire hanger 44 tapered piece of thread first the circumference of the conveyor roller 16 applied. That of the Fangnut 33 for Guide tube 18 running thread piece is on the sliding edge 34 of the Wire bracket 44 out. Here, the expiring thread piece from the scope of Rolls 16 and 17 continued. This situation is characterized by a middle position of Wire bracket 44 during the investment process in Figure 2 and 3 dashed lines represented by II.

In a landing position, which is indicated by III, is the Fangnut 33 of the wire bracket 44 on the inlet side 35. This is the of the Guide tube 12 to the catch groove 33 tapered piece of thread after wrapping the conveying roller 16 is applied to the circumference of the overflow roller 17. With progressive Movement is the thread from the catch groove 33 on the inlet side laterally next to the rollers 16 and 17 released. The thread 24 is now with a Looping led to the rollers 16 and 17. From the overflow roller 17 passes the thread in the suction end 42 of the guide tube 18. The wire bow 44 is now further guided in the direction of wrap, so that as the progresses Movement of the wire hanger 44 of the thread between the overrun roller 17 and the Guide tube 18 is caught again by the catching groove 33.

The investment process will depend on the number of desired Wraps on the rollers 16 and 17 repeated several times.

The application device shown in FIGS. 2 and 3 is exemplary. So could the Movement of the thread guide as described by rotation or by a Guide means, which is a pivoting movement or a combination between a pivoting movement and a parallel to the longitudinal axis carried out reciprocating motion. Likewise, the embodiment of the Thread guide 27 by way of example. For example, the tapered Thread piece through a separate thread guide and the expiring thread piece also be guided by a second separate thread guide. The Thread guides could be moved together or separately by guide means become.

As an example, another application device is shown in FIGS. 4 and 5. In FIG. 4 is a front view and FIG. 5 is a side view of the delivery mechanism 14 with the embodiment of the contactor 15 shown.
