Definitions

  • 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 which each have two high and two low, opposing stops. In accordance with the jacquard 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 are held in place at the end of the switching stroke.
  • the jacquard needles and thus the displacement elements have one complete working stroke, i.e. one revolution of the warp knitting machine. have to do a full reciprocation. This means that the displacement elements are suddenly moved back and forth between the sliding elements and, accordingly, the laying rail suddenly changes its position.
  • 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 adjusting 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 displacement element is designed as a roller which is displaceable along a control cam which is arranged on a sliding element.
  • DE-A-29 26 928 shows a control arrangement for a model gearbox for a warp knitting machine of a fundamentally different type.
  • a laying bar is not driven by a total gearbox, but rather by means of a complicated alternating drive device which has a cam disk and a guided one Has lever, which actuates a coupling via a plunger, which in turn generates an up and down movement in an offset lever, which then finally drives the laying rail or laying bar via further transmission members.
  • the assembly containing the total transmission is only used to control the swivel path of the offset lever, the assembly also being extremely complicated. It contains two slide rails that are connected via a handlebar to a probe element that interacts with the offset lever.
  • the probe element Due to the up and down movement, the probe element is moved up and down and one of the sliding slides is moved alternately.
  • Each of the slide valves is coupled to offset elements which are connected to a jacquard device.
  • two sets of such displacement elements have to be activated simultaneously. From this it follows without further ado that not only does a double set of jacquard control elements have to be present, but moreover the entire drive is very complex and complex and is therefore also correspondingly sluggish and prone to wear.
  • the known device is thus not only expensive but also limited in terms of performance in terms of control and drive.
  • 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 member via a connecting link in such a way that each drive element only has to perform one stroke per revolution of the warp knitting machine in order to actuate the coupling member. 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.
  • Such negative dobby or jacquard machines operating according to the double stroke method are known, for example, from "Hans Walter Kipp, Bandwebtechnik, Frick 1988, pages 47 to 77".
  • 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 according to claim 8.
  • a particularly simple design of the displacement element is defined in claim 9.
  • 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 of 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.
  • 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 between displacement elements 8,81, 82, 83 arranged displacement elements 121, 122, 123, 124, which are biased into 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 working in the double stroke process, as described, for example, in "Hans Walter Kipp, Bandwebtechnik, Frick 1988, pages 47 to 77".
  • Each displacement element 121, 122, 123, 124 contains a first section 22 of width B1, which merges via a transition section 24 into a second section 26 of greater width B2.
  • the displacement elements 121, 122, 123, 124 are straight on one side, the last displacement element 124 being supported on rollers 28 of a fixed element 30, while the other displacement elements 121, 122, 123 are each supported on rollers of sliding elements 8,81, Support 82, 83.
  • the straight side 27 opposite side 32 forms due to the first section 22, the transition section 24 and the second section 26, a cam 34, on which a driving roller 36 of an adjacent sliding element 8,81, 82, 83 is supported.
  • the sliding elements 8,81, 82, 83 are movably mounted in a guide 38 of the machine frame 40.
  • the difference in widths B2 - B1 of the second section 26 and the first section 22 of the displacement elements 121, 122, 123, 124 correspond to the displacement stages S1, S2, S3, S4, the sizes of which correspond to the geometric series 1: 2: 4: 8 :. .
  • the displacement elements 121, 122 and 124 are in the basic position, in which they are biased by means of the return springs 6.
  • the displacement element 123 is in the second, the control position, in which it has the parts in the direction of the laying rail of the summation gear and the laying rail itself has been displaced by the displacement stage S3.
  • Figures 2 to 4 show the detail of a warp knitting machine with a further sum gear 42, in which the displacement elements 441, 442, 443, 444 are each designed as swivel members, the pivot axes 46 are in the displacement of the sliding elements 481, 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, 484 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 441, 442, 443, 444 can be moved from the basic position shown in FIG. be 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 (as described in DE-A-2 204 815) for one displacement element in each case.
  • 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 element 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 interacts 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 management facilities interacts with the associated stop, as a result of which 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 assigned to 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 operative 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.
  • 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. It is readily apparent that the construction can also be carried out by appropriate structural measures such that the retaining hooks 96, 98 are held in the release position by means of their springs 104 and can be brought into the operative position by means of the electromagnets 106, 108.
  • 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 associated retaining hooks, are moved back by the force exerted on the deflection roller 76 by means of the coupling elements. If the tension 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 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 implemented in a known manner, e.g. in the form of a punch card, a magnetic recording on a magnetic tape or with the help of a computer's sample memory.
