Definitions

  • the invention relates to a pattern warping machine with a warping drum, which has a rotation axis and a circumference, are arranged on the transport surfaces which are movable parallel to the axis of rotation, and a yarn guide assembly having at least one yarn guide, the between a working position, in which he a thread the periphery of the warping drum leads, and a rest position in which he leads the thread in front of a front side of the warping drum, is displaceable, wherein the warping drum and the thread guide assembly are rotatable relative to each other and on the front side of the warping drum a thread receiving device is arranged.
  • Such a sample warper is for example out EP 2 284 304 B1 known.
  • the thread take-up device is designed as a cord or wire or as a monofilament.
  • a pattern warper is used to create so-called pattern strings or short chains.
  • threads are guided around the circumference of the warping drum and stored on the transport surfaces.
  • the transport areas For example, they are designed as revolving conveyor belts.
  • several threads, which form a so-called band are simultaneously guided around the circumference of the warping drum.
  • the wound tape is offset so that a new tape can be wound onto the already wound tape.
  • the corresponding yarn guide is then shifted so that it leads the thread in front of the end face of the warping drum.
  • the thread is then no longer stored on the circumference of the warping drum, but on the thread take-up device.
  • the thread take-up device has a much smaller circumference than the warping drum, so that the thread is indeed wound, the yarn consumption per revolution, however, remains much smaller.
  • the invention is based, to allow a good winding quality even with a large number of threads the task.
  • the thread receiving device is divided into at least two sections, of which a portion as a receiving portion on which threads under tension can be accommodated, and a portion as a transport section to which the threads (6 , 6b) are convertible from the receiving portion and with which the threads are movable away from the end face of the warping drum, is formed.
  • the sections are adapted to their respective task.
  • the receiving section then serves to accommodate the threads, which are still under a certain tension at this time.
  • the receiving portion is thus designed so that it can absorb the tensile forces caused thereby.
  • the transport section serves to move the threads away from the front side of the warping drum. The threads are transferred from the receiving section to the transport section.
  • the receiving portion is formed rigid. This achieves a defined position at which the threads taken out from the warping process are wound up.
  • the term "rigid" means that the receiving portion can deform only in an allowable tolerance range when the tension forces applied by the threads act on the receiving portion.
  • the receiving portion is formed as a hollow spindle through which a yarn transport device is guided in the transport section.
  • the hollow spindle can be relatively easily dimensioned so that they can absorb the tensile stresses generated by the threads. If the threads are then transferred from the hollow spindle to the thread transport device, then the thread transport device can convey away the quasi tension-free threads easily.
  • the hollow spindle has a thread tensioning drive.
  • the thread tensioning drive causes the hollow spindle to rotate. If you turn the warping drum when warping the threads, then you can rotate the hollow spindle, for example, at the same speed as the warping drum. But this is not absolutely necessary. In many Cases, it will also be sufficient to rotate the hollow spindle at a lower speed than the warping drum. It should only be ensured that the threads that are wound onto the hollow spindle, are held under a tension that prevent loosening of the threads of the hollow spindle.
  • the thread transport device is designed as a cord, tape or wire.
  • the wire may be formed of metal or plastic. In the latter case, it is preferably designed as a monofilament.
  • the cord or band may be formed of plastic, optionally with reinforcing fibers.
  • the receiving portion has a conveyor.
  • the threads slip from the receiving portion in the transport section, when a certain degree of filling of the receiving portion is reached.
  • you provide a conveyor then you can carry the threads that are wound in the receiving section, specifically in the transport section.
  • the conveyor has a conveyor drive. It is therefore not dependent on a transport performance, which is caused by the rotation of the warping drum and the thread guide assembly relative to each other. Rather, you can selectively drive the conveyor by the conveyor drive.
  • the conveyor drive has an adjustable conveying speed. With the setting of the conveying speed you can, for example, different requirements when winding the threads take into account. If more threads are taken out of the warping process at the same time, you can, for example, a higher conveying speed Select as if only a few threads are taken out of the warping process.
  • the conveyor has a helically guided transport track, which surrounds the hollow spindle. If the threads get into this helically guided transport track, then they are automatically moved in the direction of the transport section during further winding. When the transport track is moved, this also results in a forced movement of the threads from the receiving section into the transport section.
  • the conveyor has a screw on.
  • the screw spindle can be formed for example by a helically guided wire or a helically guided plastic wall.
  • the transport track then automatically results in the gaps between adjacent turns of the screw.
  • the screw spindle can be rotatably arranged on the hollow spindle in order to transfer the threads from the receiving section into the transport section.
  • the conveyor drive is designed as a rotary drive, which is connected to the screw.
  • the rotary drive then acts directly or via a gear on the screw to set them in rotation. This is a relatively simple design to ensure the removal of the threads that are wound on the receiving portion on the transport section.
  • the thread receiving device is mounted in front of the end face of the warping drum.
  • a bearing device is provided in front of the front side of the warping drum, in which then, for example, the hollow spindle and the screw are mounted, in which case the corresponding drives can be provided.
  • the receiving portion and the warping drum overlap in a direction parallel to the axis of rotation.
  • the receiving portion protrudes into the warping drum parallel to the direction of the axis of rotation. This eliminates the risk that a thread is not wound up on the receiving section, but on the transport section.
  • a separating device which separates threads between a support area on the warping drum and a support area on the thread take-up device.
  • the threads which are guided by the thread guide device on the thread take-up device, remain unaffected by the separating device. So you keep the state of tension for these threads always upright, so that this can result in no winding errors.
  • 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.
  • the warping drum 2 can by a not shown Shear drive, which may for example be arranged in the base 3, be set in rotation or rotation, as shown by an arrow 4.
  • a plurality of transport surfaces are arranged, which can be moved parallel to the axis of rotation of the warping drum 2.
  • the transport surfaces may be formed, for example, as circulating belts, which are not shown in detail.
  • thread bobbins 5 are arranged stationarily in a gate, not shown, ie the thread bobbins 5 are - at least in a Schrvorgang - arranged relative to the base 3 stationary. From each bobbin 5, a thread 6a or 6b is withdrawn and guided by a thread guide, not shown, which should be symbolized here by a double arrow 7.
  • 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-rotatably with respect to the axis of rotation of the warping drum 2 and can only move parallel to the axis of the warping drum 2.
  • the threads 6b which are guided in front of the end face of the warping drum 2, are received by a thread take-up device 8.
  • the thread take-up device is mounted on a machine frame 9, that is arranged in a stationary manner in front of the end face of the warping drum 2.
  • the thread take-up device 8 is directed in the direction of the warping drum 2 out.
  • the thread take-up device 8 is subdivided into two sections, of which a first section is designed as a receiving section 10 and a second section as a transport section 11.
  • the receiving portion 10 has a hollow shaft 12 which is rotatably mounted on the machine frame 9.
  • the hollow shaft 12 is connected to a thread tensioning drive 13 (only in Fig. 1 shown), which drives the hollow shaft 12 in the direction of rotation of the warping drum 2.
  • the speed of the hollow shaft 12 can be brought into conformity with the speed of the warping drum 2. However, this is not essential. It is also sufficient if the hollow shaft 12 is rotated at a lower speed.
  • the hollow shaft 12 is rigid, d. H. the tensile forces applied by the threads 6 are insufficient to deform the hollow shaft 12 beyond a predetermined amount. This dimension is chosen so small that you get no noticeable imbalances or eccentricities.
  • the thread transport device 14 may be formed as a cord, tape or wire.
  • the wire may be formed of a metal or a plastic. In the latter case, it is preferable to use a monofilament.
  • the thread transport device 14 may also be reinforced, for example by fibers such as glass or carbon fibers.
  • the thread transport device 14 is unwound from a supply roll 15 and wound onto a take-up roll 16.
  • a screw 17 is rotatably mounted on the hollow shaft 12.
  • the screw spindle 17 may for example be formed from a helically bent wire made of metal or plastic.
  • the screw 17 has a plurality of turns, between which a Transport track 18 is formed.
  • the screw spindle 17 can by a conveyor drive 19 (only in Fig. 1 shown) are set in rotation.
  • the conveyor drive 19 may for example be connected via a toothed belt pulley 20 with the screw 17. Accordingly, the conveyor drive 19 may be formed as a rotary drive.
  • the conveyor drive 19 has an adjustable conveying speed.
  • the threads 6b When the threads 6b are wound on the thread take-up device 8 by the thread bobbins 5, they first pass in the receiving section 10 onto the hollow shaft 12, which, as mentioned above, can not appreciably deform. Accordingly, the hollow shaft 12 is aligned with the axis of rotation of the warping drum 2 and the threads 6 do not experience any kind of eccentricity or vibration by the thread take-up device 8.
  • the conveyor device designed as a screw spindle 17 is also put into operation.
  • the screw shaft 17 is rotated, the threads 6b are displaced in the direction of an arrow 21.
  • the speed at which the threads 6b are displaced in the direction of the arrow 21, that is to say the conveying speed, can be made dependent on the number of threads 6b simultaneously wound onto the thread take-up device. However, the conveying speed can also be kept constant.
  • the threads 6b which reach the transport device 14 and are designated there for the purpose of distinction as threads 22, are no longer under the tension with which they are wound onto the hollow shaft 12, which is due, inter alia, to the fact that the thread transport device 14th has a much smaller diameter than the hollow shaft 12. Accordingly, the thread take-up device 14 not significantly deformed. On the other hand, such a deformation would also play no role, because the wound on the yarn transport device 14 threads 22 are no longer directly with the yarn guides (double arrow 7) in conjunction.
  • threads 22 run back to the warping drum. These threads 22 form the portion of the threads that results when the threads are removed from the patterning process.
  • An only schematically illustrated separating device 23 is provided to sever the threads 22 between a support area on the warping drum and a support area on the thread receiving device 8. The separated threads no longer interfere when the thread transport device 14 is wound onto the take-up reel 16.
  • Fig. 1 can be seen overlap the warping drum 2 and the receiving portion 10 of the thread receiving device 8, so as to ensure that the threads 6b, which are no longer wound on the circumference of the warping drum 2, in any case reach the receiving portion 10 of the thread receiving device 8 and not directly on the thread transport device 14 of the transport section 11.
