Definitions

  • the invention relates to a sample warping machine with a warping drum, on the periphery of a plurality of transport surfaces are arranged, which are movable parallel to the axis of the warping drum, a yarn guide device having at least one yarn guide, the between a position in the axial direction in front of the front side of the warping drum and a position behind the front side of the warping drum is displaceable, and an auxiliary transport device which is movable parallel to the axis of the warping drum through the end face.
  • the invention relates to a method for producing a pattern chain, in which one stores threads on transport surfaces, which are arranged on the circumference of a warping drum and movable parallel to the axis of the warping drum are, wherein a temporarily unnecessary thread using a thread guide moves in front of the front side of the warping drum and wound on an auxiliary transport device which moves parallel to the axis of the warping drum through the front side of the warping drum.
  • Such a sample warper is for example out EP 1 930 489 A1 known.
  • the warping drum is locked against rotation and the thread guides move. They pull the threads off a rotary gate that turns at the same speed as the thread guides.
  • a similar sample warping machine is off DE 100 61 491 C1 known.
  • the auxiliary transport device moves at about the same speed as the conveyor belts which are arranged on the circumference of the warping drum.
  • Another sample warping machine is off EP 1 479 806 A2 known.
  • the auxiliary transport device moves faster than the conveyor belts, so that no unnecessary thread accumulation can result on the auxiliary transport device.
  • a pattern warping machine in which the warping drum rotates as the threads are wound around their circumference.
  • the yarn guides are held non-rotatable with respect to the axis of the warping drum and the yarns can be withdrawn from spools arranged in a stationary gate. If here threads are taken out of the patterning process, so are not performed around the circumference of the warping drum, then they are wound on an auxiliary winding body whose diameter is smaller by a factor of 5 to 10 than the diameter of the warping drum. On this auxiliary winding body, however, only a limited space for receiving the unneeded threads is available. In addition, the thread consumption is relatively large here.
  • the invention has for its object to achieve high productivity.
  • auxiliary transport device moves in two directions.
  • the auxiliary transport device is moved in the axial direction of the warping drum. So it can not result in a larger diameter when several threads are wound on top of each other.
  • the auxiliary transport device is rotated so that it continuously maintains a certain tension in the threads not wound onto the circumference of the warping drum. It avoids therefore that result from misaligned threads Fortabritten or even yarn breaks.
  • threads When threads are removed from the warping process and later used again, they form a "V" with the auxiliary transport device as the lowest point.
  • the auxiliary transport device is flexible and has a clamping device which holds the auxiliary transport device in a working area in an extended state, wherein the clamping device and the rotary drive at least at one end of the work area.
  • a thin auxiliary transport device which may be formed for example as a cord or wire, however, has a very low rigidity. She is flexible. In order to be able to carry out the winding nevertheless, one uses the tensioning device, which holds the auxiliary transport device in an extended state, preferably along the axis of the warping drum. The tensioning device and the rotary drive then act together at least at one end on the auxiliary transport device. This results in a relatively simple construction.
  • the rotational drive of the auxiliary transport device has the same rotational speed at both positions.
  • the auxiliary transport device is therefore not loaded on torsion. Accordingly, it only has to withstand the tension of the tensioning device and the tension of the threads wound on the auxiliary transporting device. This allows a cost-effective design of the auxiliary transport device.
  • the rotary drive has a drive speed for the auxiliary transport device, which corresponds at most to the rotational speed of the shear drive for the warping drum. You can then control the rotary drive so that it maintains a sufficient tension in the threads, which have been taken out of the warping process, but at the same time keep the thread consumption small. This is in many Cases already possible when the rotary drive operates at a much lower speed than the shear drive. If V-threads are present, it may be useful to use the same speeds. If V-threads are only temporarily present during a warping operation, for example because V-threads have been cut off later, it may be useful to reduce the rotational speed in periods without V-threads.
  • the shear drive and the rotary drive are synchronized with each other. This means that a predetermined ratio can be set between the speed of the drogue drive and the rotational speed of the rotary drive.
  • the auxiliary transport device passes through the warping drum in the axial direction. This avoids that you have to accommodate parts of the auxiliary transport device, such as the clamping device or the rotary drive within the rotating warping drum.
  • the construction can thus be kept simple.
  • a waste receptacle co-rotating with the end of the auxiliary transport device is arranged at one end of the auxiliary transport device.
  • This waste receptacle can have several configurations. It may be a collecting container that rotates with the auxiliary transport device. It may also be a coil on which the end of the auxiliary transport device is wound up.
  • the warping drum is supported by a hollow shaft on a base and the auxiliary transport device is passed through the hollow shaft.
  • the auxiliary transport device is thus not hindered by the storage of the warping drum in their function.
  • the auxiliary transport device at each end to a coil which is about a coil axis and to the axis of the warping drum is rotatable.
  • the rotation about the spool axis can be used to maintain the tension in the auxiliary transport device.
  • the rotation about the axis of the warping drum is used to maintain the tension in the threads wound on the auxiliary transport means.
  • a Hilfsaufwickel Scheme is arranged on he auxiliary transport device in front of the front side of the warping drum and next to the Hilfsaufwickel Scheme a support means for the auxiliary transport device is arranged.
  • the auxiliary take-up area is the area where the thread guides shift the threads that are not needed in the patterning operation to wind them on the auxiliary transporting device. With a fixed gate, these threads then basically all exert a tensile force on the auxiliary transporting device from approximately the same direction. This tensile force can counteract the support means, so that the deformation of the auxiliary transport device can be kept small.
  • the object is achieved in a method of the type mentioned fact that the yarn guide device is non-rotatable with respect to the axis of the warping drum and that you turn the warping drum when laying the threads on the transport surfaces and you rotate the auxiliary transport device at least when at least one thread has been guided in front of the front side of the warping drum, wherein the auxiliary transport device at two in a direction parallel to the axis of the warping drum has a distance from each other having positions.
  • the Threads can be pulled off a fixed gate. Needles that are not required for patterning can still be guided in front of the end face of the warping drum and then form the V-threads explained above. In these V-threads, a certain tension is maintained by turning the auxiliary transporting device. Since the auxiliary transport device is also moved in the axial direction of the warping drum, no thread accumulation can form here, which leads to an excessively large diameter. The thread consumption of the unnecessary threads is kept small.
  • the auxiliary transport device be rotated at a minimum speed at which a predetermined minimum tension results in each thread which is wound onto the auxiliary transport device. So you can choose the peripheral speed of the auxiliary transport device much lower than the peripheral speed of the warping drum and still ensure that the necessary tension is maintained in each thread that is wound on the auxiliary transport device. Mistakes or thread breaks can be reliably avoided.
  • the speed of the auxiliary transport device can be increased up to the speed of the warping drum, if V-threads are present.
  • the auxiliary transport device is preferably supported next to an auxiliary winding region, onto which the threads which are not wound onto the warping drum are wound up. As stated above, this prevents the auxiliary transport device from deforming to a certain extent under the effect of the tensile forces exerted by the threads.
  • a sample warping machine 1 which may also be referred to as a short warp warping machine, has a warping drum 2, which is rotatably mounted on a base 3. This is how this is done in Fig. 2 can be seen, the warping drum 2 attached to a hollow shaft 4, which is mounted in the base 3 via two bearings 5, 6, and can be rotated by rotation or rotation shown schematically by a Shurantrieb 7, as shown by an arrow 8 , Distributed on the circumference of the warping drum a plurality of transport surfaces 9 are arranged, which can be moved parallel to the axis of the warping drum 2.
  • the transport surfaces 9 may be formed, for example, as circumferential bands, which are not shown in detail. For details of such bands can on the above-mentioned EP 1 930 489 A1 to get expelled. They are in Fig. 1 not shown.
  • thread bobbins 10 are arranged stationarily in a gate, not shown, ie the thread bobbins 10 are - at least in a warping - arranged relative to the machine frame 3 stationary. From each bobbin 10 is a Thread 11 subtracted and passed through a thread guide, which should be symbolized here by a double arrow 12.
  • the thread guides can be designed as in EP 1 930 489 A1 is shown, with the difference that the yarn guides are held non-rotatable with respect to the axis of the warping drum 2 and can only move parallel to the axis of the warping drum 2.
  • An auxiliary transport device 13 which may be formed as a cord or wire or as a monofilament, is guided through the hollow shaft 4, i. she passes through the warping drum 2 and the base 3 in full length.
  • the auxiliary transport device 13 is moved in the direction of an arrow 14, that is, on the front side at which the threads 11 are wound onto the warping drum 2, into the warping drum 2.
  • the auxiliary transport device 13 can also be moved out of the warping drum.
  • the auxiliary transport device 13 is unwound from a bobbin 15, which is arranged on a fixed to the base 3 arranged stand 16.
  • the coil 15 is braked.
  • a further coil 17 is arranged, which can be driven by a drive 18.
  • the auxiliary transport device can therefore be flexible and yet have a stretched state during operation.
  • the coil 15 is rotated by a rotary drive 19 in the direction of an arrow 20.
  • the spool 17 is rotated by a rotary drive 21 in the direction of an arrow 22. Both coils 15, 17 are rotated about the same axis as the warping drum 2.
  • the effective directions of shear drive 7 and the two rotary drives 19, 21 are identical, as can be seen by comparing the arrows 8, 20 and 22.
  • a thread 11 has been taken out of the warping process and temporarily not stored on the circumference of the warping drum 2, then it is stored on the auxiliary transport device 13, which rotates in the same direction to the warping drum 2 and optionally with the same speed as the warping drum 2 and thereby generates a certain tension in the thread 11, which has been performed in front of the end face of the warping drum 2.
  • the speed n1 of the warping drum does not necessarily coincide with the speed n2 of the auxiliary transport device 13. It is even possible that the auxiliary transport device 13 rotates at a slightly lower speed than the warping drum 2, for example, when the V-threads have been cut, because they are no longer needed. However, you can of course the warping drum 2 and the auxiliary transport device 13 rotate at the same speeds. In this case, the coil 17, for example, on be secured to the hollow shaft 4 and the rotary drive 21 then forms a unit with the shear drive. 7
  • a support means 23 which supports the auxiliary transporting means 13 in the vicinity of a region in which the threads taken out from the warping process are wound up. This area can also be referred to as "auxiliary take-up area”.
  • the spool 17 accommodates not only the auxiliary transporting device 13 but also the threads which have been wound on the auxiliary transporting device 13. Accordingly, it can also be referred to as waste reception.
  • the representation in the Fig. 1 and 2 is, as mentioned above, highly schematized. In Fig. 1 are not shown for reasons of clarity, the transport surfaces 9. Also not shown are part, cutting and cross bars, which are needed later to produce the actual chain from the endless wound threads.
  • the warping drum is stopped and the threads 11 are severed in certain areas.
  • the chain thus formed can then be transferred to a tree, wherein the warping drum 2 is rotated in opposite directions.
