Definitions

  • the invention relates to a drive device for the knife carriage on a Double carpet weaving machine for separating upper and lower fabrics, with a guide roller arranged over both sides of the double carpet fabric guided traction means, the traction means positively with a single, drive means rotating in alternating directions is connected and wherein the knife carriage is movable in a guide over a stroke range which is larger than the width of the double carpet fabric.
  • a drive device for the knife carriage of this type is described in GB 890 393.
  • the knife carriage is driven by a cord.
  • the both ends of the cord are attached to a smooth rope drum and are alternately wound onto the rope drum and then unwound again.
  • the rope drum is driven by the motor in changing directions The direction of rotation of the motor can be switched by limit switches.
  • the motor is together with the cable drum on the side of the fabric web and in large distance below the cutting plane.
  • the ratio of the maximum length of the pulling strand to the minimum length the pulling dream is very big. With almost the same loads There is traction by the knife carriage in the area of the stroke reversal different stretches in the pulling strand. The knife carriage moves depending on the weaving machine speed around uncontrollable and different ways beyond the specified stroke. It is not possible Any manipulations on the knife carriage in restricted areas (Check the knife, sharpen the knife or readjust the Knife) during the stroke reversal. The different movement characteristics of the knife carriage within the tissue to be separated depending on the direction of movement of the knife carriage leads to different Pole heights, which are also caused by a subsequent shearing process Pole layer can no longer be removed. The disadvantages described increase with increasing web speed.
  • the cable drum is driven by a computer-controlled motor (servo motor).
  • the control of the drive motor can be done depending on the Correct the respective machine speed.
  • the motor is on the side near the plane of movement of the knife carriage outside the tissue.
  • Another embodiment variant proposes both guide wheels to drive a toothed belt drive by means of synchronized motors. This results in a higher reliability of the drive itself.
  • the disadvantage however, is that the device and control effort is significantly increased.
  • An additional drive also requires additional ones Space that is just in the area of the fabric edges because of the necessary Access to the operating area of the weaving unit is not sufficiently available.
  • the object of the invention is to provide the overstroke of the knife carriage different working speeds of the weaving machine and the cutting device to be low and controllable in the area of both fabric edges and all pile rows reliable and even at high weaving speeds to cut under almost the same conditions, so that a high surface quality the carpets can be guaranteed.
  • This arrangement ensures that the almost uniform and significantly shorter lengths of the traction means reduced the pretension of the same can be. This reduces the load on the traction mechanism. The differences in length in the respective pulling runs of the traction means can clearly on one lower levels can be reduced.
  • the movement characteristics of the knife carriage is the same in both directions. Different speeds of the knife, especially when entering the tissue, are avoided. The quality of the two carpets separated from each other is visibly better.
  • the drive device with servo motor according to claim 6 is particularly suitable on weaving machines on which the fabric width is to be changed frequently.
  • the weaving zone of the double carpet weaving machine 1 is essentially determined by the Shed image elements (not designated) and the sley 121 shown.
  • the Weblade 121 swings around the shop shaft 12 in the usual way to the weaving zone led double carpet fabric 5 is with the help of a changing directions across the width of the fabric moving knife carriage 2 separated into an upper fabric 51 and a lower fabric 52.
  • the knife of the knife carriage 2 separates the upper goods 51 and lower goods 52 stretched pole handle in the middle between the two basic goods.
  • the knife carriage 2 is guided exactly on a guide 13, so that Knives from the prescribed path in the vertical direction should not be used can deviate.
  • the knife carriage 2 is regularly driven so that it during the Production of a row of poles is moved once across the width of the fabric 5. If a further row of poles is formed, it moves at the same speed back. Depending on the selected pole material and the stability of the knife the cutting process can also be carried out at a lower speed become. In this case, however, more than one row of pole handles must be used for a stroke be cut with one cut.
  • toothed belt 21 for driving the knife been used.
  • This toothed belt 21 is with the knife carriage 2 in Area of the upper run firmly connected.
  • the toothed belt 21 is on the outer guide rollers 15, 15 'and over the inner guide rollers 16, 16' from and led to the drive means 23.
  • Drive means a toothed belt pulley 23, the teeth of course the Timing belt 21 is adjusted.
  • This gear 23 is driven in the example of FIGS. 1 and 2 by means of servo motor 3.
  • the respective drive movement of this servo motor 3 is usual Show the control unit 31.
  • the drive movement of the servo motor 3 can predefined using different, selectable programs and, if necessary, depending on them be corrected by certain measured values.
  • the rope drum 24 is preferably on its circumference in a proven manner with spiral grooves provided, in each of which a single rope 22 with a part of its cross section can insert in an orderly manner.
  • FIGS. 3 and 4 are intended to clarify which relationships between the arrangement of the drive means, the length of the traction means and their elongation ⁇ and load exist.
  • the total length and thus the proportional total elongation of the traction means 21, 22 is plotted on the X axis. Parallel to this are the two end positions A, B and the middle position M of the knife carriage 2, matched to the position of the drive means 23, 24 marked.
  • the Y-axis shows the mechanical rope force F in the respective traction device at one assumed uniform working speed of the weaving machine. Analogous to the well-known tension diagrams when calculating screws becomes the operating force for the knife slide positions A, M, B. FB applied accordingly.
