Definitions

  • Warp knitting machine in particular crochet gallon machine
  • the invention relates to a warp knitting machine, in particular a crochet gallon machine according to the preamble of claim 1.
  • Such a warp knitting machine is known for example from DE-PS 467 899.
  • a jacquard mechanism serves as the adjusting device, the displacement elements being actuated by changing levers, each having two high and two low, opposing stops. According to the Jacguard card, these are brought into the area of stop rails that oscillate in cycles in such a way that the displacement elements are adjusted by them in a pattern and held in place at the end of the switching stroke.
  • the jacquard needles and thus the displacement elements complete a complete working stroke, i.e. one revolution of the warp knitting machine. have to do a full reciprocation. This means that the displacing elements are suddenly moved back and forth between the sliding elements and, accordingly, the laying rail changes position suddenly.
  • warp knitting machine not only has a complicated structure, but is also subject to high wear and noise. Accordingly, the warp knitting machine can only be operated with a relatively low number of turns.
  • DE-PS 31 17 683 describes a further warp knitting machine of the type mentioned at the outset, the actuating devices each having an eccentric which can be rotated by 180 ° with each actuation and which is connected to a displacement element by means of a form-fitting coupling element.
  • This ousting ment is designed as a roller which is displaceable along a control cam which is arranged on a sliding element.
  • the object of the invention is to design a warp knitting machine of the type mentioned at the outset in such a way that it enables higher performance with a simple construction.
  • the object is achieved according to the invention by the characterizing features of claim 1.
  • the double stroke means that two push-pull drive elements act on the coupling element via a connecting element in such a way that each drive element has to perform only one stroke per revolution of the warp knitting machine in order to actuate the coupling element. Accordingly, such a warp knitting machine can be operated at a significantly higher drive speed, and yet the displacement elements move gently. This leads to higher speeds of the warp knitting machine with at the same time reduced wear and reduced noise pollution.
  • Claim 2 describes an advantageous embodiment of the actuating device, which can preferably be developed according to claim 3. It is useful if each pulling element of the adjusting device is guided according to claim 4 and the displacement is limited by a stop element. An embodiment according to claims 5 to 7 is advantageous for holding the tension element.
  • a particularly smooth running of the warp knitting machine results in a configuration of the coupling element as a flexible traction element.
  • a particularly simple design of the displacement element is defined in claim 9. But an embodiment of the displacement element according to claim 10 is also possible.
  • the provision of the displacement element by means of pretensioning is facilitated by an embodiment according to claim 11.
  • An embodiment according to claim 12 and in the further development according to claim 13 is particularly advantageous.
  • An expedient solution to the control is described in claim 14. Wear and noise of the warp knitting machine can be reduced by a further development according to claim 15 and / or 16.
  • Figure 1 shows a first control device for the
  • Figure 2 shows a second control device for the offset movement of a lay rail of the warp knitting machine in a view transverse to the longitudinal axis of the lay rail;
  • Figure 3 shows a displacement element of the control device of Figure 2
  • Figure 4 shows the displacement element of Figure 3 in
  • Figure 5 shows an actuating device for the control device in the detail.
  • FIG. 1 shows the detail of a warp knitting machine, specifically a control device for the offset movement of a laying rail 4 provided with thread guides 2.
  • the laying rail 4 is prestressed against a sliding element 8 of a summation gear 10 by means of a return spring 6.
  • the latter contains displacement elements 12 1 , 12 2 , 12 3 , 12 4 arranged between displacement elements 8,8 1 , 8 2 , 8 3 , which are prestressed into a position by means of springs 14.
  • the displacement elements 12 are connected via coupling elements 16 in the form of flexible traction elements to a control device 18 which can be controlled according to the model.
  • the coupling members 16 can either be straight through or run over deflection rollers 20.
  • the adjusting device (not shown in more detail) is a negative dobby or jacquard machine operating in the double stroke process, as described, for example, in "Hans Walter Kipp, Bandwebtechnik, Frick 1988, pages 47 to 77".
  • Each displacement element 12 1 , 12 2 , 12 3 , 12 4 contains a first section 22 of width B 1 , which merges via a transition section 24 into a second section 26 of greater width B 2 .
  • the displacing elements 12 1 , 12 2 , 12 3 , 12 4 are straight on one side, the last displacing element 12 4 being supported on rollers 28 of a fixed element 30, while the other displacing elements 12 1 , 12 2 , 12 3 are each supported Support on rollers of sliding elements 8,8 1 , 8 2 , 8 3 . Due to the first section 22, the transition section 24 and the second section 26, the side 32 opposite the straight side 27 forms a control cam 34, on each of which a driving roller 36 of an adjacent sliding element 8,8 1 , 8 2 , 8 3 is supported. The sliding elements 8,8 1 , 8 2 , 8 3 are movably mounted in a guide 38 of the machine frame 40.
  • the difference in the widths B 2 - B 1 of the second section 26 and the first section 22 of the displacement elements 12 1 , 12 2 , 12 3 , 12 4 correspond to the displacement stages S 1 , S 2 , S 3 , S 4 , the sizes of which are geometrical Row 1: 2: 4: 8: correspond.
  • the displacement elements 12 2 , 12 2 and 12 4 are in the basic position, into which they are prestressed by means of the return springs 6.
  • the displacement element 123 is in the second, the control position, in which it has displaced the parts of the summation gear lying in the direction of the laying rail and the laying rail itself by the displacement stage S 3 .
  • Figures 2 to 4 show the detail of a warp knitting machine with a further sum gear 42, in which the displacement elements 44 1 , 44 2 , 44 3 , 44 4 are each designed as pivoting elements, the pivot axes 46 of which lie in the displacement path of the sliding elements 482,482,483,484.
  • the sliding elements are reduced in this example to guide rollers which are guided in a guide 50 of the machine frame 52.
  • the displacement element has a first section 54 with the radius R 1 , which merges via a transition section 56 into a second section 58 with a larger radius R 2 .
  • the sections 54, 56, 58 form a control cam 60, on which a driving roller 62 of the respective sliding element 48 1 , 48 2 , 48 3 , 48 4 is supported.
  • the driving roller 62 is mounted on the pivot axis 46 of the sliding elements, as can be seen in particular from FIGS. 3 and 4.
  • the displacement elements 44 1 , 44 2 , 44 3 , 44 4 can be removed from the basic position shown in FIG. 2, in which the driver rollers 62 on the first section 54 of the displacement elements 44 1 , 44 2 , 44 3 , 44 4 are pending, are pivoted into the switching position in which the driver rollers 62 are in contact with the second section 58 of the displacement elements.
  • FIG. 5 shows a section of a preferred adjusting device 18, 68 for one displacement element each.
  • This has two pull elements 70, 72 which can be moved back and forth in a push-pull manner between end positions and which are connected to one another via a connecting element 74.
  • This connecting member 74 runs over a deflection roller 76, the axis 78 of which is guided to and fro in a fixed guide 80.
  • a coupling member 16, 64 for the displacement elements of the summation gears 10, 42 of FIGS. 1 and 2 is connected to the axis 78.
  • a stop 82, 84 is fastened to each tension element 70, 72, each of which cooperate with guide devices 86, 88 driven to and fro. The latter are moved by driven crank pins 90.
  • Each guide device 86, 88 is provided with an opening through which the tension element 70, 72 is guided.
  • Each of the leaders directions cooperates with the associated stop, whereby the forces exerted by the guide device on the stop act symmetrically, so that no force components acting transversely to the direction of movement of the tension elements occur.
  • a hook 92, 94 is associated with each pulling element at the free end, which cooperate with stationary retaining hooks 96, 98.
  • the retaining hooks 96, 98 are rotatably mounted about fixed axes 100, 102 and are connected to a spring 104, 106, which holds the associated retaining hook 96, 98 in an active position in which the retaining hook 96, 98 can engage behind the hook 92, 94 of the tension element 70, 72 , whereby the tension element is held in the appropriate position.
  • the retaining hooks 96, 98 are designed as armatures for electromagnets 106, 108. If the electromagnets are energized by a power source (not shown) of a pattern device, the retaining hooks 96, 98 are tightened and moved from their operative position into a release position in which they no longer interact with the hooks of the tension elements 70, 72.
  • the hooks 92, 94 are also moved in a push-pull manner between two positions A and B, for as long as the retaining hooks 96, 98 are held in their release position.
  • the guide devices 86, 88 move from position A to position B, they rest on the stops 82, 84 and cause the pulling elements 70, 72 to move against the retaining hooks 96, 98.
  • the guide devices 86, 88 move from position B to position A, then the Pulling elements 70, 72, if they are not held in place by their assigned retaining hooks, are moved back by the force exerted on the deflection roller 76 by means of the coupling elements. If the pulling elements 70, 72, as described, are reciprocated between their two end positions, the deflection roller 76 remains in its upper end position shown in the figure under the action of the spring force of the coupling elements.
  • the retaining hook 96 is in its operative position due to the action of the spring 104, in which the retaining hook 96 holds the hook 92 of the tension element 70 holds in place. If in the next cycle the other hook 94 is moved against the retaining hook 98 in the manner described, the deflection roller 76 with its axis 78 in the guide 80 is moved against the pretensioning force of the coupling element into the position 76 'shown in dashed lines in FIG. 5, as a result of which Coupling member and the associated displacement element is moved from the basic position to the switching position. The deflection roller 76 now remains in its lower position 76 'as long as the hooks 92, 94 are locked with the retaining hooks 96, 98.
  • the excitation and de-excitation of the electromagnets 106, 108 and thus the control of the retaining hooks 96, 98 and thus also the tension elements 70, 72 is optionally carried out by the control program of a sample device, not shown, according to the position of the laying rail determined by the desired laying of the thread.
  • a control program can be carried out in a known manner, for example in the form of a punch card, a magnetic recording on a magnetic tape or with the aid of a computer's sample memory.
