Definitions

  • the invention relates to a method and a device for applying multiple synthetic threads to a winding machine according to the preambles of claims 1 and 6.
  • multifilament threads are made of synthetic polymers.
  • the synthetic polymer such as a polyester or a polyamide, extruded in melt-liquid form by means of spinnerets, cooled, stretched and wound into coils to complete the process.
  • This winding is implemented by means of a winding machine, as is known, for example from EP2147137 Bl.
  • the threads touch the rewinder on so-called head thread guides. These thread guides serve to allow the threads to be flipped and fed by means of several traversing means. By this Flin- and Herstructure with simultaneous rotation of a winding spindle, the coils are formed.
  • the head thread guides are designed as rollers, so that friction influences on the threads are minimized.
  • the threads must be applied to the rewinder, and in particular to the head thread guides.
  • the threads are mito e performed a suction gun.
  • a thread guide carrier is used to apply the threads to the head thread guides, the head thread guides being fastened to the thread guide carrier. This yarn guide carrier is manually led out of the reel-up to apply the threads successively on one end side of the reeling machine to the individual head thread guide.
  • the application is greatly simplified by the fact that the application occurs almost at one position.
  • a suction gun by means of which the threads are guided during the application process, has to be moved only slightly during this application process.
  • the movement of the suction gun can be carried out for example by an operator or by a robot. If the suction gun is guided by an operator, this operator can pay close attention to the handling of the suction gun.
  • the movement of the head thread guides is indeed carried out using the infinite conveyor.
  • a robot for guiding the suction gun must have a low complexity due to the method according to the invention.
  • the simplifications of the application method described above result in that the application can be carried out more quickly and more reliably, ie with fewer false attempts.
  • each head thread guide is guided on a separate guideway. Because of these separate guideways, the application of the threads to the head thread guides is further facilitated, as explained below.
  • the suction gun is held at a defined position, so that the threads pass by a certain distance from each other on the conveyor.
  • the threadline of each thread crosses an associated guideway of the head thread guide. If the head thread guides are now transferred by means of the conveying means from a waiting position into the operating position, then each thread is automatically taken over by the associated head thread guide on the front side of the winding machine without the suction gun having to be moved.
  • At the front of the rewinder is the so-called application position of the head thread guide.
  • the infinite conveying means is moved at an angle to the axis of a winding spindle of the winding machine. This ensures that the head thread guides, despite their movement on different guideways in their operating positions are each arranged centrally above the associated winding unit. This is necessary to wrap coils of high quality. Each head thread guide has the same distance and the same position to the its associated winding unit.
  • all the head thread guides are moved on a common track.
  • This allows a particularly simple construction of the infinite conveyor and the attached overhead thread guide, as well as their arrangement in the on winding machine.
  • Such a simple construction is inexpensive to produce, especially since many parts are identical.
  • this simplicity leads to a particularly robust behavior of the device during operation and in addition to a simple control.
  • the head thread guides are attached to an infinite funding, by means of which the movement of the head thread guide on the front side of the take-up machine is over past.
  • the device for applying a plurality of synthetic threads takes up very little space. At any time of the operation of the application device, whether the head thread guides are in a waiting, applying or in an operating position, the device hardly projects out of the winding machine.
  • Such a device by means of an infinite conveyor is structurally simple and inexpensive to implement.
  • the separation of the functions of the movement of the head thread guide and the movement of the Saugpis- tole by different energy sources leads to the application of the threads to the head thread guide is easy to carry out.
  • the process of applying the threads to the head thread guides can be implemented quickly and with few failures.
  • each head thread guide is arranged with a different distance to the funding out, or attached to this.
  • the head thread guides are on different guideways feasible. This fact allows the suction gun to be held in a fixed position during the application process, with each head thread guide taking over the associated thread as it passes the yarn sheet. The fact that the suction gun does not have to be moved during the application process to the head thread guide facilitates this process considerably.
  • the conveyor is arranged in an embodiment of the invention at an angle to the axis of the winding spindle. This is necessary in order to achieve a high and over all winding units uniform thread quality.
  • This angle of the conveying means to the axis of the winding spindle is to be observed in particular, or close to the operating position in order to achieve the said advantage. In the following areas, the angle plays a minor role.
  • the head thread guides are designed as rolls. These rollers are connected by means of a respective axis of rotation with the conveyor.
  • angles are formed between the direction of movement of the conveying means and the axes of rotation of the head thread guides, these angles in each case have the same values as the above-mentioned angle between the direction of movement of the conveyor and the axis of the winding spindle.
  • the conveying means is arranged such that its direction of movement runs in the operating range of the head thread guide parallel to the axis of the winding spindle.
  • each head thread guide with the same distance to the funding attached to this.
  • the length of all axes through which this attachment is implemented is the same.
  • the head thread guides are therefore feasible on one and the same guideway.
  • two adjacent head thread guides each have an equal distance from one another. This ensures that all coils with the same width have a constant quality.
  • the conveyor is designed as a chain, then no variation of the positions of the head thread guide is possible, which could lead to inconsistent thread or coil quality.
  • Such a chain is simple in construction and thus inexpensive to buy. The life of such a chain is also very long.
  • the apparatus shown above is used in particular in take-up machines for winding partially or fully drawn synthetic threads for textile or technical fields of application as well as crimped threads for the carpet industry.
