Definitions

  • the invention relates to a warp knitting machine with at least a Musterlegebarre, the multiple yarn guide having, by a drive in the offset direction are movable back and forth, being between the yarn guides and the drive is arranged a tension element.
  • Such a warp knitting machine is known from DE 101 37 601 A1 known.
  • the yarn guides are on wires or Wire ropes hung on both ends via tension straps are connected with clamping elements, so that on both ends of the wire ropes exerted the same force becomes.
  • a drive motor to the drive wheel Strap is looped, therefore, only the forces apply, which required to move the thread guide are. But he does not have to muster any powers that for tensioning a spring or other tensioning device required are.
  • the clamping devices are it is designed as an air cylinder, which the clamping force maintained by the pressure of air.
  • the invention is based on the object, the effects to keep small from disturbances.
  • This object is in a warp knitting machine of mentioned type solved in that one on the Traction element acting holding device is provided.
  • the holding device As soon as there is a risk that the clamping forces on the Tension elements become too small or even disappear, the holding device is triggered. The holding device then holds the tension element or the tension elements firmly in a predetermined position. From this position the tension element can not fall out, even if the Gravity acts on the tension element. Accordingly the restart is much easier. you only has to solve the holding device. This happens, after the required forces or pressures again have been constructed to tension the tension member to keep. Once the tension element is stretched, it can never leave his position.
  • the holding device is a clamping device educated.
  • This is a particularly simple embodiment a holding device.
  • the tension element is simply pinched. The occurring friction forces are enough to make the tension element in the desired Hold position.
  • the tension element is at least in the range the holding device formed band-like.
  • a band has the advantage that it is two substantially parallel and has flat sides.
  • the Holding device is designed as a clamping device, Easy handling is possible. You just have to use a tool that works on both sides of the band acts with a force sufficient to the to generate necessary friction.
  • a plurality of tension elements are provided and the holding device acts simultaneously on a Group of tension elements. So you do not have to do it for everyone Tension element provide its own holding device. Much more you can summarize the tension elements in groups and for a plurality of tension members a common Use holding device. This saves space and simplifies the control. It must be assumed that the use of the holding device always is required for all tension elements at the same time, at least for all tension elements of a group.
  • the drawbars of Group lie on each other. This is especially true advantageous if the drawbars in the area of Holding device are formed band-like. In this Case you can press the individual bands on each other. If this happens with a sufficient force, the not even overly big, then the Bands held reliably in position.
  • a guide device is arranged, which the Tensile elements parallel to the direction of movement of the holding device leads. If the holding device, for example is designed as a clamping device, then secures the guide means, however, that the bands can swerve laterally when compressed. The Holding device then sets together with the guide device also when triggering the holding process, that the bands remain in their positions.
  • the holding device acts simultaneously on several groups of tension elements, the groups have the same height.
  • the holding device is in a holding direction prestressed and has a tensioning drive.
  • the holding device automatically releases off when an auxiliary power, for example Compressed air or electricity, disappears or decreases so much that they the holding force of the holding device can not overcome.
  • an auxiliary power for example Compressed air or electricity
  • the holding device a Compression spring has.
  • a compression spring is a constructive simple component. In operation, so in trouble-free Condition, the compression spring is cocked, for example by compressed air or by a magnetic force. When the power disappears and accordingly the compression spring are no longer tensioned can, then the tension elements by the holding device recorded.
  • the holding device has a movable head part, that interacts with an anvil.
  • the headboard For example, by the above-mentioned compression spring to be moved.
  • Other drives are of course as well possible.
  • the head part is a deformable Having face.
  • a deformable face then adapts to the contour of the tension elements or the tension element on and holds the tension element or the tension elements firmly.
  • the deformable headboard is also able to smaller height differences between adjacent groups compensate, so that with a holding device several groups of tension elements are held can.
  • the head part is formed of a polymer.
  • a polymeric plastic has the advantage that it is inexpensive. So you can the headboard as a wearing part Consider exchanging this from time to time can be.
  • a polymer, i. a polymeric Plastic is also flexible enough to surface differences absorb when applying the tension elements to be able to.
  • the anvil is movable towards the head part. In this case, not only the head part is moved, but also the anvil. This ensures that the tension element or the tension elements by the clamping between the headboard and the anvil not too strongly deflected will or will be. The load of the tension elements so it is kept small.
  • a stop as Wegbegrenzung intended for the anvil.
  • the anvil can So only move to a predetermined position. This position is chosen so that the tension elements a have optimal course. Especially with short ones Tension elements, the deflection is kept within limits.
  • the anvil has a drive, which is stronger than the drive of the head part.
  • This can be realized for example by the fact that the head part is moved by a drive element that For example, a compression spring has, during the Anvil acted upon by two similar drive elements is, accordingly, a total of two compression springs exhibit. This will ensure that the position of the anvil defined only by the stop is, but not changed by the power of the head part can be.
  • the tension element only on one side a drive on, passing it on the other side a deflection roller is guided to a tensioning device, which has a circumferential groove, at least on her in the direction of gravity lower end by a stationary Holding element is covered.
  • the tension element is So not stretched between two clamping devices, but it's just between the drive at one end and the tensioning device at the other end established.
  • the clamping device their clamping force loses, then the tension elements in the area of Drive held by the holding device.
  • holding is not required because the tension elements held there to the pulleys are.
  • This bracket is structurally relative easy.
  • the tension elements, for example, at this end can be designed as wire ropes are here simply held in a groove of the pulleys, from which they can not escape.
  • a plurality of pulleys next to each other are arranged, with a gap between adjacent ones Pulleys is smaller than the smallest Cross sectional dimension of the tension element in the region of Gap.
  • the tension elements, the pulleys also do not leave the side, because the guide groove the pulleys in this area through the adjacent pulley is covered. Only at the outermost pulley is another type of cover required.
