Definitions

  • the invention relates to a guide bar assembly of a warp knitting machine with at least one thread guide, which is movable by a drive means in an offset direction back and forth, wherein the drive means comprises a drive and a return means, between which a drive element is arranged.
  • Such a guide bar arrangement is made DE 101 37 601 B4 known.
  • Such a guide bar arrangement is also referred to as a "string barre".
  • the yarn guide is attached to the drive element.
  • the drive element is formed relatively thin. To keep it taut, the drive element must permanently loaded on train. For this purpose, clamping devices are provided in the known case at both ends. On one side of the drive element of the drive is arranged.
  • a warp knitting machine should be able to work with the highest possible working speed.
  • the working speed is often expressed in "revolutions per minute”. At each turn, a loop is usually formed.
  • Working speeds of about 4,000 rpm are currently possible.
  • the frequency at which a resonance phenomenon occurs can be shifted by increasing the forces acting on the drive element.
  • the reset device is set "harder” and the drive must also be dimensioned stronger so that he can work against the power of a properly trained restoring device.
  • the invention has for its object to achieve a higher operating speed in a warp knitting machine.
  • the drive function for the thread guide is decoupled from the support function for the thread guide.
  • the drive element no longer carries the thread guide.
  • the position of the thread guide is so no longer changed by a change in the drive element.
  • the drive element can be subjected to significantly higher tensile forces than before. These forces can be so great that it comes to an elongation of the drive element. This elongation can be greater than a needle pitch, ie a distance between two knitting needles.
  • a change in length is not critical because you only have a single connection between the drive element and the support element. Accordingly, a change in length of the drive element does not transfer to the carrier element. If a yarn guide is arranged on the carrier element, then it retains its position, which is predetermined by the carrier element, regardless of how strongly the drive element is loaded by tensile forces.
  • At least two thread guides are attached to the support element, which form a group of yarn guides.
  • a guide bar arrangement has, for each drive element, a group of thread guides arranged, for example, in a repeat determined by a pattern. In this case, it is particularly important that the individual thread guides maintain their mutual distance. Since the thread guides are arranged on the carrier element, which is not acted upon by tensile forces, there is no risk that changes in position of the thread guide caused by change in length of the drive element.
  • the drive element is resistant to tensile stress and the carrier element is tensile and pressure-resistant.
  • the Drive element can therefore be flexible or limp because it is acted upon by its two ends with sufficiently large tensile forces.
  • the carrier element is acted upon by drive forces only at one point, namely at the connection between the carrier element and the drive element. It is thus pushed and pulled alternately. So that the yarn guide or yarn guides maintain the desired positions during such movements, a tensile and pressure-stable design of the carrier element is advantageous.
  • the carrier element is formed from a metal, in particular from steel or aluminum, or from a plastic, in particular a fiber-reinforced plastic.
  • Metal or fiber reinforced plastic have sufficient strength to absorb tensile and compressive forces.
  • a plastic usually has the advantage that it is not subject to changes in length, which are thermally induced.
  • the carrier element is designed as a tube.
  • a tube which can be referred to as a "tube” due to its small diameter, has high bending stability with low mass.
  • the drive element is passed through the carrier element. So you need it virtually no additional space, although the drive element and the support element are functionally separated from each other.
  • the drive element can lengthen within the carrier element, if it is acted upon by tensile forces, without the carrier element undergoes a corresponding change in length.
  • the carrier element is arranged next to the drive element. It then saves the threading of the drive element in the support element. In addition, it is no longer necessary that the drive element has a corresponding through cavity.
  • the carrier element and the drive element are at a distance from one another. It thus avoids that the support element and the drive element abut each other. A change in length of the drive element then does not affect the carrier element. The drive element can thus be acted upon with sufficiently large clamping forces.
  • connection is preferably arranged closer to the drive than to the return device.
  • the drive defines the movement of the drive element and thus also the movement of the carrier element with the thread guides or the. The closer the connection is arranged to the drive, the less effects of influences that can be caused by a change in length of the drive element.
  • connection is arranged at the end of the carrier element, which is adjacent to the drive. This is the maximum achievable position for the connection.
  • the remainder of the drive element between the connection and the drive can be kept relatively short, so that the effects of changes in length of the drive element on the motion control of the support element are practically negligible.
  • Fig. 1 shows in a highly schematic form a guide bar arrangement 1 of a warp knitting machine, not shown.
  • the guide bar assembly has a plurality of yarn guides 2, two of which are shown.
  • the thread guides 2 have the form of a laying or perforated needle.
  • the yarn guides 2 are moved by a drive element 3, which, however, can only transmit tensile forces.
  • the drive element 3 may, for example, as a thin rope Wire or plastic, be designed as a wire or a flat band.
  • material for the drive element are metal, especially steel, plastic or fiber composites into consideration. Since the drive element is formed slippery, it must be acted upon at its two ends with oppositely directed tensile forces to retain its extended position.
  • the drive element 3 is guided in a bar body 4.
  • the ingot body 4 may for example have a guide groove, which is not shown in detail.
  • a plurality of drive elements 3 are arranged in the barrel body 4 in order to be able to control different groups of thread guides 2.
  • the yarn guides 2 are to be moved during operation of the warp knitting machine for stitch formation in an offset direction 5, which is shown here by a double arrow.
  • the offset direction usually corresponds to the longitudinal direction of the bar body 4 and thus also to the longitudinal direction of the drive element 3.
  • a drive 6 which acts on the drive element 3.
  • the drive 6 is shown here as a linear drive. But it is also possible to form the drive 6 as a rotary drive, taking appropriate measures are to translate a rotary motion into a translational motion.
  • the other end of the drive element 3 is connected to a return device 7.
  • the return device 7 is shown in the present case as a spring. It can for example be designed as a helical spring. But it is also possible to realize the return means in other ways, for example by a piston-cylinder unit which is acted upon by a pressurized fluid.
  • Fig. 1 illustrated guide bar assembly
  • the drive frequency comes within a range in which the natural frequency of the guide bar assembly 1 is located.
  • This natural frequency is essentially determined by the restoring device 7. It is possible to increase this natural frequency by increasing the force exerted by the restoring device 7 and, for example, using a harder spring here. Of course, in this case, the drive 6 must be made correspondingly stronger.
  • connection 9 is arranged closer to the drive 6 than to the return device 7.
  • the connection 9 is arranged at the end of the carrier element 8, which is adjacent to the drive 6. Accordingly, an elongation of the drive element 3 by high tensile forces only in the area between the connection 9 and the drive 6 has an effect. Since this section can be kept relatively short, it can be neglected.
  • the support member may also be formed of a metal, preferably steel or aluminum, or of a plastic, which is preferably fiber-reinforced, that forms a fiber composite material.
  • the support member 8 may be formed as a wire or rod or as a band. In a preferred embodiment, it is designed as a tube, ie as a tube with a relatively small diameter. Such a tube has a comparable bending stability to a solid rod with reduced mass. The moving mass can then be kept small.
  • a distance 10 between the drive member 3 and the support member 8 is arranged. It is thus prevented that the drive element 3 and the carrier element 8 abut each other and thus a length influencing of the carrier element 8 could be effected by friction.
  • Fig. 3 shows an embodiment in which the support member 8 is formed as a tube through which the drive element 3 is passed.
  • the connection 9 between the drive member 3 and the support member 8 is provided.
  • This compound 9 can be formed here for example by a plastic potting compound. If the drive element 3 has a diameter which is substantially smaller than the inner diameter of the carrier element 8, and the drive element 3 is kept taut, then the risk that a friction between the drive element 3 and gives the support member 8, by which the length of the support member 8 could be changed, comparatively small.
  • the guide bar assembly is still small and light.
  • the moving mass can also be kept small.
