Definitions

  • the present invention relates to an insertion device according to the preamble of claim 1.
  • Patent specification EP 0 093 078 shows laying elements in the form of toothed racks, which are anchored in carrier racks, which in turn are slidably mounted in carrier members along the weaving rotor in order to carry out a laying stroke.
  • Devices of this type are relatively heavy and the moving masses are accelerated and braked for each stroke.
  • due to the friction paths corresponding to the stroke length, power losses, frictional heat and abrasion, and the laying strips must be made with relatively large cross sections so that the warp threads do not deform or deform too much.
  • a reading device is known from the document EP-A-0 154 148, in which laying rails (control rods) are arranged on a pivotable frame.
  • the object of the invention is to create a reading device in which the disadvantages mentioned are eliminated by separating the reading process into a deflection and reading process.
  • the advantages of the invention are to be seen essentially in the fact that the load on the laying rail due to the warp threads is significantly reduced, that the laying rail can be constructed in a lightweight construction over large weaving widths, that is to say with little mass, and that a higher reading speed is achieved.
  • the row shed weaving machine shows a row shed weaving machine with a weaving rotor 1, which is equipped with combs 2 and on which the warp threads 3 are guided over an angular range for shedding, and with an insertion device 4 in order to insert the warp threads 3 into the existing gaps 5.
  • the row shed weaving machine also contains a warp beam 6, a match beam 7, a breast beam 8 and a goods beam 9.
  • the reading device in question consists essentially of a number of laying rails 10, which are arranged at a distance from the weaving rotor 1 and parallel to the weaving rotor axis of rotation, and a holding device 11 for the laying rails 10 and a drive device 12 extend over the length of the weaving rotor to move the laying rails 10 back and forth in the direction of the weaving rotor axis in such a way that the warp threads 3 are read into predetermined gaps 5 of the combs 4 rotating past according to a program.
  • the laying rails 10 are held in a holding device 11, which comprises a carrier 13 arranged parallel to the rotor axis, a number of spaced-apart and identically oriented holders 14 which are fixedly connected to the carrier 13 and guide rails which are fixedly connected to the holders 14 and which are at least the same Have the same length as the weaving rotor 1 or at least cover the width of the warp thread.
  • FIG. 2 shows a cross section of a preferred embodiment of an arrangement of the laying rail 10.
  • the laying rail 10 consists of a sheet metal profile with two in parallel sections 21, 22 which run to one another and have different lengths, and an intermediate connecting section 23 which is inclined with respect to the sections 21, 22.
  • Each laying rail 10 is assigned to a guide rail 25.
  • the laying rail 10 is slidably mounted on the guide rail 25.
  • a recess 26 is provided on the upper side of the guide rail 25, which extends in the longitudinal direction of the guide rail over its length.
  • the laying rail 10 is provided with a strip-shaped guide member 27 which can be secured by suitable means, e.g. is spot welded to the inside of the long section 21.
  • the laying rail 10 is arranged to slide back and forth in the recess 26 in the longitudinal direction of the guide rail 25 and is secured against lifting off by a section of the holder 14.
  • the guide rail 25 has a first and a second rounded section 28, 29 on the narrow sides in order to deflect the warp thread 3 to be inserted. Furthermore, a channel-shaped recess 30 is provided in the guide rail 25, which is formed in the underside of the guide rail in order to prevent warp threads from being pinched between the guide rail and the holder 14.
  • FIG. 3 Another embodiment of the arrangement of the laying rail 10 is shown in FIG. 3.
  • the laying rail 10 consists of the same sheet profile as in the embodiment described above.
  • the guide rail 31 has a substantially rectangular cross section and has a slot-like recess 32 on, which is formed parallel to the side surfaces and starting from a narrow side. This recess 32 extends in the longitudinal direction over the length of the guide rail.
  • a guide wedge 33 is provided for guiding the laying rail 10.
  • an elongated hole is provided in the long section 21 of the sheet metal profile, which is dimensioned such that the laying rail 10 can be moved back and forth over a predetermined length in the longitudinal direction of the guide rail.
  • a number of guide wedges 33 are provided which are arranged at a predetermined distance from one another.
  • the guide rail 31 has a first and a second rounded section 34, 35 on the narrow sides in order to deflect the warp thread 3 to be inserted. Furthermore, the guide rail 31, like the guide rail 25 of the first embodiment, can have a groove-shaped recess.
  • the guide rails 25 and 31 are arranged in the holder 14 such that the end section of the short section 22 of the laying rail 10 is arranged at a predetermined distance with respect to the long section 21 of the adjacent laying rail 10.
  • the laying rail 37 consists of an essentially L-shaped sheet metal profile with a long leg 38 which is connected to the guide rail 25 stands and with a short leg 39 in which the recesses 24 are formed for guiding the warp thread 3. It is pointed out that this laying rail 37 can also be used in an arrangement according to FIG. 3.
  • the laying rail 10 can also be mounted by means of rolling elements 40 instead of slidingly.
  • FIGS. 2 to 4 show examples of raceways of the warp threads in order to explain the function of the laying rail arrangement.
  • the warp threads 3 to be inserted are deflected twice. These deflections take place either on one and the same guide rail 25 (FIG. 2) or on two adjacent guide rails 31 (FIG. 3), specifically on the first and second rounded sections 28, 29 and 34, 35 provided for this purpose.
  • the first deflection of the Warp thread 3 on the first section 28 or 34 is provided for the thread run-in and serves to pre-align the warp thread 3 to be inserted onto the recess 24 in the laying rail 10.
  • the second deflection of the warp thread 3 on the second section 29 or 35 is provided for shed formation and forms the support point aligned with the recess 24 in the laying rail 10 for deflecting the warp thread to be read in parallel to the weaving rotor axis for reading into the shedding high and low points and transversely to the weaving rotor axis during shedding, so that laying rail 10 largely relieves the warp thread tension, only that warp thread 3 to be read in only deflects parallel to the weaving rotor axis. From the above it can be seen that the laying rail 10 can advantageously be made low in mass, which in turn has an advantageous effect on the reading speed.
  • FIGS. 6a to 6e show contours of the recesses 24 intended for guiding the warp thread 3, which are formed in a row in the connecting section 23 of the laying rail 10.
  • the preferred embodiment of the recess 24 is shown in Fig. 6a.
  • This recess has a slit-shaped section 41, into which the warp thread 3 to be read is guided during the reading process, and an adjoining widened section 42, which is intended to use a suitable tool to e.g. pull a needle into the recess and when the warp thread is unloaded, e.g. in the event of warp and / or weft defects, take up the relaxed warp thread.
  • a recess in the form of an elongated hole can also be provided.
