Definitions

  • the thread guide elements may be formed by double fork-part rods, each of which is mounted in a linear guide and having at least one guide opening or a guide gap for at least one thread.
  • the term rod in this context means any elongate element, e.g. also a flat lamella or the like.
  • the thread guide elements can also be formed by guide pieces, each of which is mounted in a guide rail and which have at least one guide opening or a guide gap. Compared to the rods, this solution has the advantage that no laterally projecting rod ends arise and that virtually the entire length of the guide rails is available for positioning.
  • the guide rails can be held in a common frame.
  • the cables are preferably guided via deflection means to a drive unit, on which all motors are preferably arranged on at least one common plane or on several parallel planes. This makes the motors easily accessible for maintenance.
  • Each thread guide element may be associated with a clamping device for clamping detection of a stationary thread. This is necessary because not all threads brought up by the creel are needed for the sharpening process.
  • Each thread guide element may also be associated with a cutting device for cutting a thread.
  • the present invention also relates to an automatic pattern warper having a device for positioning the threads as described above.
  • the invention also relates to a use of the automatic skinning machine.
  • the invention relates to a high performance automatic patterning machine which can be used in particular for webbing.
  • the automatic pattern machines available on the market can in some cases be used for more complex productions, even if the average processing time is too long in comparison to conventional machines.
  • the first concept envisages winding up a single thread, which is selected from a limited set, generally comprising at least 6 and at most 12 threads.
  • a single thread which is selected from a limited set, generally comprising at least 6 and at most 12 threads.
  • Such a system is powered by a small gate placed on the floor in front of the machine in the axial direction of the drum.
  • Each thread is wound by a system which can be more simply defined as one or more pivot arms, which in this case are arranged in a star-shaped concentric fashion around the head of the drum and cause the thread to be rotated tangentially around the roller.
  • This system has a number of important limitations; this includes the very long production time measured in direct relation to the threads of the warp and their length, as well as a tension on the irregularly wound surface, because the part descending on the roll or drum is much less taut compared to the rising part. This is due to the fact that the ascending wound thread is removed from the gate and thereby more tensioned while When descending wound thread the opposite occurs.
  • the selection of the threads and their length is determined by a warping program.
  • the threads are not placed directly on the winding surface, but their direction is diverted by a system on it; this raises a number of problems with regard to the chain quality and the tightness of the threads in their specified sequence, a defect that is even more important in the processing of particularly electrostatic or smooth yarns such as viscose or silk. Processing is in some cases only possible if major compromises are accepted.
  • rollers on which run the double fork part bars profiled.
  • Each double-forked sub-rod is moved independently of the others by means of a carbon-fiber-reinforced cord whose two ends are fixed in two channels in the middle part of said double-forked sub-rod.
  • said loading device is located near the right side of the positioning device, it is curved and touches the warping drum at one point; said loader rotates at an angle of not more than 180 ° about the warper drum; this allows the attachment of the pre-marked threads to the warping drum, preventing them from sticking in order to avoid tearing.
  • each thread (1) can immediately take one of the 32 positions according to the Scharan eleven.
  • the double thread sheet A consists of 32 double fork part rods 2, which can move transversely and are guided laterally on correspondingly shaped rollers 3.
  • the frame of double thread sheet A forms a base plate 4 with the long slots 5 for drive cords and eight attached bolts 6; four of them are used alternately to insert a set of spacers 7 and louvers 8; they form the solid part of double thread sheet A and are closed with an upper plate 9.
  • the other four bolts are used to insert the set of rollers 3, which from the Slats 8 and the spacers are separated, which allow the rotation of the outer part of the roller 3 itself.
  • Each double-fork sub-rod 2 is moved independently of the others via a carbon-fiber-reinforced cord 19, the two ends of which are fixed in two channels in the middle part of the double-fork sub-rod 2.
  • Each end of the cord 19 is guided over a deflector 10 in the underlying lamella 8 and through the long slot 5 on the base plate 4.
  • Each double-fork sub-bar 2 shifts a single warp thread as it moves, since the thread passes through the central portion of the double-fork sub-bar 2 (guide opening 15).
  • Each drive plate 13 houses sixteen V-shaped stepper drives 12 (eight on each side); the deflection takes place via a loose disk 14. This arrangement was chosen because it optimizes the dimensions of the assembly.
  • the stepper drives 12 are controlled by intelligent drives, which are networked together with a PC-based control unit.
  • Reference numerals 21 and 22 indicate the arrangement of the threads in the vertical order: the threads remain vertically separated from each other and therefore can independently transition into a horizontal order without crossing each other.
  • a further advantage is that, unlike the conventional warping system (with warp blade), the threads are generally inserted with a number of two to fourteen into each tooth of the double thread A; while there are usually four to eight, which is why twisting or torsion problems lead to spiral thread crossovers that can cause problems in the subsequent weaving phase.
  • the threads are completely free from the double thread sheet A to the point of winding, which could lead to problems in the warping phase due to the static nature of the yarn or the mechanical effect of the wind produced by the rotation of the warping drum or by the yarn itself becomes. In certain cases, this may or may result in poor chain quality.
  • rollers 24, 25 both rotate freely around their own axis. These rollers 24, 25 are normally closed, as in Figure 5 shown; however, before and during the entire reading process they are open, roller 25 in direction 26 and roller 24 in direction 27.
  • the direction of the threads is indicated by an arrow 28.
  • reference numeral 29 which represents the winding surface of the warp, the yarns are rearranged in the horizontal direction, as is already done in sectioning. As a result, an ideal process technology ensures high quality for the process.
  • the machine can be used universally for automatic skinning on an increased scale.
  • the double fork part rods 2 of the double thread A are moved to the attachment position; this position allows a lance called “loader” to pick up all the strings, then to synchronize with the roller (technically referred to as “flying cut”) and attach the threads to the roller.
  • the double-forked partial bars 2 of the double-threading sheet A have essentially three working positions or areas: a) warping and eyelet area, b) area for holding the threads, c) area for attaching the threads.
  • the warping drum 40 consists of a single unit.
  • the warping drum 40 In the first case, the warping drum 40 consists of a single unit.
  • the warping drum 40 In the second case, however, shown in Figure 7 , is the warping drum 40 completely cylindrical, and the conical part 42 is an independent unit that moves with ball bushing guides on it.
  • FIG. 9 a section of warping drum 40 and parts thereof for an automatic machine with fixed crossbars and movable cone shown.
  • the system works in almost the same way as the system with reference to Figure 8 is illustrated; the difference is that the part bars are not pulled out; Rather, it is the chain that is taken by the belt 43 and moved in the direction of arrow C.
  • the conical portion 42 in this case is a part which is fixedly connected to the belts 43 normally in monofilament warping machines be used; in turn, the presence of conical portion 42 constitutes novelty presented in accordance with the present invention. Said conical portion 42 moves rearwardly to provide an important support for building the chain.
  • the horizontal order of the arrangement of the threads is independent of the vertical order in which they are in the "double thread" A, because in the shift threads are not superimposed on each other.
  • the threads can assume a predetermined order but also positions that are variable relative to one another (such as in cases where different yarn numbers or types are sharpened). This operation can be performed without stopping the motor of the winding roller or the warping drum 40.
  • the system provides a thread holding mechanism that makes it possible to keep each thread independent.
  • the entire chain is sharpened in such a way that the number of threads located in the double thread A is added adjacently; the program determines each time a new winding starts at the beginning of the roll, and this applies to the entire chain.
  • FIG. 10 schematically shows a warping machine 39 with a warping drum 40 with a cylindrical part 41 and a conical part 42, wherein as already in connection with FIG. 7 mentioned, the surface of the cylindrical part 41 is formed by movable belt 43.
  • the conical part 42 is displaceable together with the belt 43 in the direction of the axis of rotation of the warping drum 40.
  • the warping drum 40 is mounted in a machine frame 55, which also receives the other elements, such as drive motor, brake device, control, etc.
  • the principle of the movable conical part with the coupled belt could under certain conditions also be used in conventional warping machines with conventional warping module.
  • Each cable pull 73 moves a guide piece 79, preferably in a guide rail 80. In certain cases, however, it would also be conceivable to keep the guide pieces freely tensioned without additional guidance by the cable pull.
  • at least one biasing spring 81 is integrated into the cable.
  • Each cable wraps around a sheave 82 which is coupled to a stepper motor 83. As a result of the looping friction on the pulley, the cable pull and thus the guide piece 79 can be moved in both directions of movement. As can be seen, the guide piece 79 does not necessarily have to execute a linear movement.
  • the guide piece could, for example, also be guided in a curved guide rail.
