Definitions

  • the invention relates to a method for producing a pattern chain, in which one stores threads using thread guides on transport surfaces, which are arranged on the circumference of a warping drum and axially parallel to the warping drum movable, and generates a yarn application, wherein the yarn guide and the transport surfaces during the depositing moved relative to each other.
  • the invention relates to a sample warping machine with a warping drum, at the periphery of which a plurality of parallel to the axis of the warping drum movable transport surfaces are arranged, and a plurality of yarn guides, with the help of threads on the transport surfaces to form a yarn application can be stored, the yarn guide and the transport surfaces parallel to Axis of the warping drum are relatively movable.
  • Such a method and such a sample warper are for example EP 1 445 361 A2 known.
  • a pattern chain which can also be referred to as a "short chain" is produced by winding one or more threads simultaneously from one end face of the warping drum around the circumference of the warping drum and thereby onto transport surfaces, which are designed, for example, as endless, circulating conveyor belts drops.
  • transport surfaces which are designed, for example, as endless, circulating conveyor belts drops.
  • the invention has for its object to produce a pattern chain with high quality.
  • This object is achieved in a method of the type mentioned in that one determines at least one parameter of the thread application on at least one transport surface and controls the relative movement between the thread guides and the transport surfaces in dependence on the determined parameter.
  • At least one of the following components is controlled in order to produce the relative movement: thread guide, laying unit, on which the thread guides are movably arranged, transport surfaces and warping drum. You can also move several of these modules controlled simultaneously to achieve the desired structure of the thread order. In principle, however, it is sufficient to move one of these assemblies in order to produce the thread application with a conically bevelled end face and an axis-parallel peripheral surface.
  • the warping drum is rotated when depositing the threads and limits the determination of the parameter to predetermined rotational positions of the warping drum. If one realizes the transport surfaces, for example, in that at the periphery of the warping drum at certain intervals conveyor belts are arranged, then there is a thread order, which has a polygonal shape. If, in this case, the determination of the parameter is limited, for example, to the rotational positions of the warping drum in which a conveyor belt is located below a measuring device, then the parameter can be determined precisely at the conveyor belts. This is sufficient in most cases, to gain enough information about the structure of the thread order, so that you can control the relative movements in a row.
  • the height of the thread application and / or the parallelism of the surface of the thread application with the axis of the warping drum and / or the slope of the free end face of the thread application are used as parameters. Often it will be enough, one of these sizes to use as a parameter. In certain cases, however, it may be beneficial to use two or three of these quantities as parameters.
  • transport surfaces are used, to which a wedge-shaped contact surface with a predetermined pitch angle is assigned at one end of a work area.
  • This pitch angle corresponds to the slope of the cone at the other axial end of the thread application.
  • a measuring device which determines at least one parameter of the thread application and which is connected to a drive control, which controls the relative movement controls between the yarn guides and the transport surfaces.
  • the aid of the measuring device determines one or more parameters of the thread application and thus to determine whether the thread application is produced in the desired manner. If this is not the case, then the relative movement between the thread guides and the transport surfaces is changed. Such relative movement is usually present during winding to produce the cone-like structure at an end face of the thread application. If the thread application does not meet the desired specifications, then the relative movement is made larger or smaller.
  • the transport surfaces at one end of a work area is assigned a wedge-shaped contact surface with a predetermined pitch angle.
  • This pitch angle corresponds to the cone angle at the other end of the thread application.
  • the abutment surface can be arranged on a wedge-shaped element which is fastened directly to the respective transport surface.
  • At least one of the following subassemblies is movable to produce the relative movement: thread guide, laying unit, on which the thread guides are movably arranged, transport surfaces and warping drum. You can also move several of these assemblies at the same time. However, the control is simplified if only one of these modules is moved at the same time. You can then use the mobility of the other modules for other functions.
  • the measuring device determines at least one of the following parameters: height of the thread application, parallelism of the surface of the thread application with the axis of the warping drum and slope of the free end face of the thread application. For example, if the surface of the thread application is not parallel to the axis of the warping drum, then the relative movement between the yarn guides and the transport surfaces is too large or too small and must be corrected accordingly. The same applies if the slope of the free end of the thread order does not meet the desired specification.
  • the measuring device is designed as a laser measuring device.
  • a laser measuring device can be used here as a distance measuring device to determine the height of the thread application, the parallelism of the surface at the periphery of the thread application with the axis of the warping drum and / or the slope of the free end of the thread application.
  • a laser measuring device has a relatively high resolution or accuracy of 30 microns. This is sufficient for most of the commonly used threads.
  • the warping drum on a rotary drive and an angle sensor, wherein the angle encoder is connected to the measuring device.
  • the angle encoder thus "clocks" the measuring device, ie it tells the measuring device, when the warping drum in Rotation angle positions is where a parameter can be determined.
  • the transport surfaces are formed by conveyor belts, which are arranged distributed at predetermined intervals on the circumference of the warping drum, such a configuration is advantageous.
  • the thread order is generated namely polygonal.
  • a measuring device that detects a distance to a fixed point would then continuously determine other measured values as the warping drum rotates. Of course you can also correct these changing measured values or move the measuring device accordingly. It is easier, however, if one makes a measurement only at predetermined circumferential points of the warping drum.
  • the measuring device is displaceable parallel to the axis of the warping drum. You can then control wider bands, for example, include 24 or 48 adjacent threads. The measuring device can then be moved periodically back and forth, for example, to monitor the structure of the thread application.
  • a memory device in which a relative movement function can be stored, wherein the memory device is connected to the drive control.
  • the memory device is connected to the drive control.
  • the figure shows a very schematic representation of a sample warping machine 1 with a warping drum 2, which has a rotary drive 3. With the aid of the rotary drive 3, the warping drum 2 is rotated in the direction of an arrow 4 when generating a pattern chain.
  • a plurality of conveyor belts 5 are arranged, which are movable in the direction of an arrow 6 by a drive, not shown.
  • the conveyor belts 5 thus form transport surfaces which are movable parallel to the axis 7 of the warping drum 2, namely when generating the pattern chain from a free end 8 to the end 9, on which the rotary drive is arranged.
  • Each conveyor belt 5 is assigned a wedge-shaped contact surface 10.
  • the wedge-shaped bearing surface 10 is attached directly to the conveyor belt 5 and is characterized together with the conveyor belt. 5 emotional. But you can also arrange the contact surfaces 10 separately from the conveyor belts 5 and move in other ways together with the conveyor belts 5.
  • the abutment surfaces 10 are located adjacent the free end 8, i. the conveyor belts 5 have been moved accordingly before the beginning of the winding.
  • the threads 11 are guided by a laying unit 14.
  • a schematically illustrated thread guide 15 is provided for each thread.
  • Each yarn guide 15 may be movable parallel to the axis 7 of the warping drum 2 relative to the laying unit 14.
  • the laying unit 14 may be movable in total parallel to the axis 7 of the warping drum 2.
  • the conveyor belts 5 are also movable and driven. They are moved so that their outer surface, i. the radially outer strand moves from the free end 8 to the other end 9. Finally, it is also provided that the warping drum 2 is displaceable in total parallel to its axis 7.
  • a thread application 17 is to be generated, which has a cone-shaped end face 18 whose inclination the slope of the contact surface 10 matches.
  • an outer circumferential surface 19 of the thread application 17 is arranged parallel to the axis 7 of the warping drum 2.
  • the measuring device 20 is parallel to the axis of the warping drum 2 displaced, as indicated by the double arrow 21.
  • the measuring device 20 determines a distance between the peripheral surface 19 of the thread application 17 and a fixed point. With the aid of the measuring device 20, it is thus possible to determine the layer thickness increase of the thread application 17. With this layer thickness increase, which results from a sequence of measurements of the thickness or the height of the thread application, one can determine the size of the relative movement between the thread guides 15 and the conveyor belts 5, which is necessary for the just-wound ribbon, so the entirety of the simultaneously wound threads 11, the angle of the contact surface 10 follows.
  • this angle can be calculated in advance. Such a determination is advantageously taken even before the beginning of the warping process, so that the first or a few turns at the beginning of the warping process with these calculated values of the "feed”, ie the relative movement between the yarn guides 15 and the conveyor belts 5, is driven. Now, it is determined with the aid of the measuring device 20, whether the set feed causes the individual turns of the ribbon so superimposed that their "front", ie the rotary drive 3 side facing abuts the contact surface 10 and thus on the other end side 18 of the desired cone angle results. If this is the case, then you can continue working with the set relative movement. If this is not the case then the relative movement has to be changed. To simplify the following explanation, the relative movement is referred to as "feed”. So if the cone angle at the end face 18 of the thread application 17 is too steep, then the feed must be increased. If it is too flat, then the feed must be reduced.
  • the circumferential surface 19 of the thread application runs parallel to the axis 7 of the warping drum 2. If one notes that the peripheral surface 19 has a slope towards the end 9, then the feed must be reduced. If a slope is towards the end 9, then the feed must be increased.
  • Another possibility is to monitor the inclination of the end face 18. If this inclination deviates from the inclination of the contact surface 10, then so is Here a corresponding correction of the feed required.
  • the relative movement can be generated in various ways. In the simplest case, only one assembly is ever moved. The other assemblies are held stationary in the direction of the axis 7 of the warping drum 2.
  • the drive control required for this purpose is not shown for reasons of clarity.
  • the conveyor belts 5 form a polygon seen from the front side of the warping drum 2 ago. Accordingly, the thread application 17 will also form a polygon. If now the warping drum 2 is rotated by the rotary drive 3 during warping, then the distance between the measuring device 20 and the surface 19 changes solely due to the polygonal structure of the thread application 17.
  • the warping drum 2 has an angle transmitter 22, which cooperates with an angle sensor 23. Accordingly, a non-illustrated drive control "knows" when the thread application 17 is supported by a conveyor belt 5 when passing by the measuring device 20. The measuring device 20 then only records measured values, for example, when a conveyor belt 5 passes under it.
