Definitions

  • the invention relates to a warp knitting machine with at least two knitting tool bars, of which at least one is attached via at least one support lever to a support lever shaft.
  • a thread guide which guides this thread must be moved relative to a knitting needle both parallel to the width direction of the knitting machine, ie in the offset direction, and perpendicular thereto. The last movement is often effected by the corresponding Wirktechnikmaschinebarre is pivoted.
  • the knitting tool bar is attached to the support lever shaft via the support levers. Also knitting needles and slides are arranged on ingots, which are pivoted.
  • the knitting tools In operation, the knitting tools must not collide with each other. Every collision leads to a malfunction where the machine has to be stopped. At a fine Needle division, the knitting tools have only a small distance from each other, so that the risk of collision of knitting tools is particularly large. Even at higher working speeds, the risk of such disruptions increases.
  • Support levers of different active tool bars may well have different dimensions and material volumes. As a result, the various support levers also expand differently. This circumstance causes the knitting tools to shift relative to each other. This is critical, for example, in the interaction of the needle and slider. This interaction is only guaranteed if the positions remain unchanged.
  • the invention has for its object to keep the risk of disturbances in the operation of a warp knitting machine small.
  • This object is achieved in a warp knitting machine of the type mentioned above in that the support lever has a tempering.
  • tempering it is possible to hold the support lever (usually a warp knitting machine will have a plurality of such support lever) at a predetermined temperature. Now you can consider the thermal expansion, which experiences the support lever at this temperature, from the beginning to accurately position the moving with the help of this support lever knitting tools.
  • the tempering device can also be at a standstill the machine to be effective, so that you already get the desired position of the knitting tools to each other when starting the warp knitting machine.
  • the temperature control also acts on the support lever shaft. Accordingly, the support lever shaft is maintained at the appropriate temperature, so that you can set the desired position of the knitting tools relatively accurately in the offset direction of the warp knitting machine, of course, the temperature is taken into account during operation.
  • the tempering acts on the support lever shaft on the support lever. This requires only that there is a heat-conducting connection between the support lever shaft and the support levers. In many cases, it is easier to temper the support shaft, because the support shaft in some sections is more accessible than the support lever itself.
  • the support lever shaft is formed as a hollow shaft and has a channel which is connected to a connection for a heat transfer medium. You can then pass the heat transfer medium through the support lever shaft to provide the support lever shaft with a predetermined temperature. This temperature then acts on the support lever. If you choose the right temperature right from the start, for example, the temperature prevailing during production with the warp knitting machine, then you can position the knitting tools very precisely to each other to keep disturbances small.
  • the heat transfer medium is formed as a liquid.
  • a liquid it is somewhat more expensive to perform a seal to the support lever shaft.
  • a liquid is much better than a gas capable of transporting or removing heat to the support lever shaft.
  • the heat transfer medium is formed as oil.
  • the heat transfer medium can then be used simultaneously for lubrication.
  • the terminal is connected to a main shaft gear housing. It can be used with the oil from the main shaft gear housing to temper the support shaft and above the support lever. Since you can bring the temperature in the main shaft gear housing already at the right temperature, the use of the appropriate oil for temperature control of the support lever shaft is basically to realize without much additional effort.
  • a volume flow regulator is arranged in the flow path of the heat transfer medium. You can then use the volumetric flow controller to adjust the temperature of the support lever shaft and the support lever. If you throttle the flow, then less heat is entered into the support shaft. Accordingly, the temperature does not increase so much. Conversely, you can increase the temperature, if the volume flow controller allows a larger flow.
  • a temperature controller is provided for the heat transfer medium is. Even with a temperature controller, it is possible to adjust the temperature of the support lever.
  • the tempering acts on the outside of the support lever. So it is basically not necessary to change the support lever.
  • the tempering device preferably has a heating wire which interacts with the support lever.
  • the heating wire for example, can be supplied with electrical energy, so that it heats up and transfers the corresponding heat to the support lever.
  • the temperature of the support lever can be adjusted within certain limits.
  • the tempering device has a radiant heater with which the support lever can be irradiated. The heat can then be transferred without contact to the support lever.
  • the tempering device has an induction arrangement. Even with an induction arrangement, energy can be transmitted without contact to the support lever, which can be used for temperature adjustment.
  • the induction assembly is capable of generating eddy currents in the support lever and / or the support lever shaft, which in turn generate electrical heat loss that increases the temperature of the support lever and / or the support lever shaft.
  • the induction arrangement can be arranged laterally next to the movement path of the support lever.
  • the tempering device has an electrical cooling element.
  • Such an element may be formed, for example, as a pelletizing element. During production, this cooling element can be used to lower the temperature of the support lever and / or the support lever shaft slightly.
  • FIG. 1 shows an effective range 1 of a warp knitting machine 2 (FIG. 3) in a schematic representation.
  • the active area 1 more knitting tools are arranged, namely a needle 3, an associated slider 4 and two guide needles 5, 6.
  • a plurality of such knitting tools 3-6 are arranged perpendicular to the plane of the drawing.
  • the direction perpendicular to the plane of the drawing is also referred to as the "offset direction". It corresponds to the direction in which the warp knitting machine 2 extends in the width direction.
  • the guide needles 5, 6 To produce a knitted fabric, the guide needles 5, 6 must be moved relative to the needle 3 so that stitches are formed.
  • the guide needles 5, 6 are doing moved back and forth in a kneading cycle in the offset direction. Between these movement sections in each case a movement takes place perpendicular to the offset direction.
  • the needle 3 is moved parallel to its longitudinal extension (with reference to FIG. 1: from bottom left to top right and back).
  • the slider 4 must close the slider needle so that the slider needle 3 can grasp a thread and pull it through the stitch.
  • the needle 3 and the slide 4 must be positioned relatively accurately to each other. If the slider is located too far away from the slider needle 3, then he may not be able to operate the slider needle 3 correctly. If the slider 4 is arranged too close to the slider needle 3, then the forces acting on the needle 3 forces may be too large.
  • Fig. 2 now shows various elements which are used for the corresponding movement of the individual knitting tools 3-6. Same elements as in Fig. 1 are provided with the same reference numerals.
  • the needles 3 are attached to a needle bar 7.
  • the needle bar 7 is arranged via a support lever 8 on a support lever shaft 9.
  • the support lever 8 is pivoted, so that the knitting needle 3 performs the above-mentioned movement.
  • the knitting needle is moved in an arc.
  • the slides 4 are attached to a slide bar 10, which are fastened via a support lever 11 to a support lever shaft 12.
  • the support lever 11 is clamped for example via a clamp 13 on the support lever shaft 12.
  • the support lever 8, 11 for the needle bar 7 and the slide bar 10 differ greatly in volume and length. Temperature changes in this area could thus lead to greatly different changes in length of the support lever 8 for the needle bar 7 and the support lever 11 for the slide bar 10. In such a change, the distance between the needles 3 on the one hand and the sliders 4 on the other hand would change unfavorably.
  • the guide needles 5, 6 are attached to guide bars 14, 15, which are arranged on support lever shaft 18 via support levers 16, 17.
  • the guide bars 14, 15 are moved by a rotational movement of the support lever shaft 18 perpendicular to the offset direction.
  • Fig. 3 the warp knitting machine 2 is shown with a main shaft housing 19, in which an oil bath 20th located.
  • the oil bath 20 is maintained at a predetermined temperature by a tempering device 21.
  • the tempering device 21 may include both a heating device 22 and a heat exchanger 23 as a cooling device.
  • the tempering device 21 ensures that the oil bath 20 has a substantially constant temperature. This temperature corresponds approximately to the temperature that occurs during operation of the warp knitting machine.
  • the support lever shaft 9 (the same applies to the support lever shaft 12, even if this is not further explained below) is designed as a hollow shaft surrounding a channel 25.
  • the channel 25 is connected via a line 26 to the oil bath 20 in connection.
  • a pump 27 delivers oil from the oil bath 20 through the conduit 26 into the support lever shaft 9.
  • a return conduit 28 delivers the oil back into the oil bath 20 after it has passed through the support lever shaft 9.
  • the support lever shaft 9 is maintained at the same temperature, which also prevails in the oil bath 20. This temperature is transmitted to the support lever 8, 11, which are thus kept at the same temperature. It is basically only necessary, the support lever 8, 11 thermally conductive to connect with the corresponding support shaft shafts 9, 12.
  • a volumetric flow controller 29 and / or a temperature controller 30 It is possible to install in the flow path of the oil a volumetric flow controller 29 and / or a temperature controller 30. With both regulators 29, 30, it is possible to influence the heat output from the oil from the oil bath 20 to the support lever shaft 9. If you let flow with the volume flow controller 29 only a little oil through the support lever shaft 9, correspondingly less heat is transmitted to the support lever shaft 9, so that the temperature increase remains lower. With a larger flow rate correspondingly more heat is transmitted to the support lever shaft 9, so that there is a correspondingly higher temperature. With the aid of the temperature controller 30, the temperature of the oil flowing through the support lever shaft 9 can be set higher or lower. In a manner not shown, it is of course possible to provide sensors which determine the temperatures at the support levers 8, 11 and / or at the support lever shafts 9, 12 in order to communicate them to the regulators 29, 30.
  • the temperature of the support lever 8, 11, 16, 17 can also be done in other ways, for example via an electrically operated heating wire, an induction heater or a radiant heater. It is also possible to arrange a cooling element on each support lever 8, 11, for example in the form of a pelletizing element.
