Definitions

  • the present invention relates to a device for distributing weft threads according to the preamble of claim 1 and a row shed loom with weft distributing device.
  • This device has the major disadvantage that the elimination of faults, for example weft breaks, clogging of the channels by weft threads, only with considerable effort is possible, and the gap between the parts is not adjustable.
  • the present invention has for its object to provide a device for distributing weft threads, which does not have the disadvantage mentioned.
  • a row shed weaving machine with a weft distributing device is characterized according to the invention by the features of claim 8.
  • Figures 1 and 2 show a section of a row shed weaving machine with a shaft 1, a weaving rotor 2 and a device for distributing weft threads.
  • the device has an essentially tubular receiving part 5 with a flange 6 which is fastened to the weaving rotor 2 and rotates with the weaving rotor 2.
  • the device comprises an annular first part 7 fastened to the flange and co-rotating with the weaving rotor 2 and an annular second part 8 which is stationary with respect to the first part 7 and which are arranged coaxially and at a distance from one another such that there is a gap 9 between them opposite end faces is present in order to avoid friction between them, and an actuating device 3 to move or open the second part 8 from a working position (FIG. 1) to a position for troubleshooting (FIG. 2).
  • channel-shaped recesses 10, 11 are formed in the form of circular arcs in the opposite end faces of the first and second parts 7, 8, respectively, towards the end face.
  • the recesses in the first part 7 are connected to the weaving rotor 2 via a channel 12, while the recesses 10 in the second part 8 are connected to thread feed devices, also not shown, via channels (not shown).
  • the second part 8 is rotatably mounted on the actuating device 3, which is arranged axially displaceable with respect to the weaving rotor 2.
  • an extension 13 is formed on the second part 8, in which a roller bearing 14 is inserted.
  • the rolling bearing 14 is arranged on the other hand on a bearing ring 15 and held thereon by means of a ring 16.
  • the receiving part 5 has at its end opposite the flange 6 a cylindrical projection 17.
  • the bearing ring 15 is axially displaceable arranged and secured against twisting by a wedge guide 18.
  • this wedge guide 18 serves to guide the actuating device 3 with the second part 8 during the axial displacement.
  • six blind bores 19 are formed, which are arranged lying on a circular line at equal intervals.
  • a clamping ring 20 with a radially inward extension 21 is placed at the free end of the extension 17, a clamping ring 20 with a radially inward extension 21 is placed.
  • the clamping ring 20 lies with the extension 21 on the end face of the extension 17 and is secured by a pin 22 which is arranged in the clamping ring 20 and projects into a recess in the extension 17.
  • Blind bores 23 are also formed in the clamping ring 20 and are aligned with the blind bores in the bearing ring 15.
  • Compression springs 24 are arranged in the blind bores 19, 23 and hold the second part 8 connected
  • the actuating device 3 has a piston arrangement with a housing part 25 and a piston 26.
  • the housing part 25 is essentially a cabbage cylinder with a first section 27, which is screwed to the second part 8 and is mounted on the roller bearing 14, and with a second section 28, in which the piston 26 is displaceably arranged to and fro.
  • the piston 26 has a hollow cylindrical section with a sealing ring on the circumference and at one end a flange with a sealing ring on the circumference.
  • the second section 28 has two sections with different internal pressure gauges, so that there is a shoulder into which an inlet channel 29 is formed.
  • the piston 26 is arranged such that the sealing rings arranged on the hollow cylindrical section and on the flange bear tightly on the inner surfaces of the partial sections and form with the shoulder an annular working chamber into which the inlet channel 29 opens.
  • the second part 8 is provided with three support units 30, which thus form a three-point support and rest on a shoulder 31 on the receiving part 5.
  • An insert body 32 made of hard metal is arranged at the support point.
  • the support unit 30 consists of a support screw 33 and a ball 35 which is rotatably held at the free end of the support screw 33.
  • the support screw 33 is screwed into a threaded bore, not shown, such that the ball 35 protrudes from the threaded bore.
  • the support screw 33 is assigned an arrangement which comprises two clamping screws 34 and an elongated hole 36, and which is provided at the location in the bearing ring 15 provided for the three-point support.
  • the elongated hole 36 penetrates the bearing ring 15 in the radial direction.
  • the slot 36 is dimensioned such that both the support screws 33 and the clamping screws 34 pass through the slot in the axial direction.
  • the clamping screws 34 are arranged on both sides of the support screws 33 and have a shaft 37 adjacent to the screw head and a threaded section 38 at the free end, which are dimensioned such that the transition section of the thread lies within the elongated hole 36.
  • the elongated hole can be deformed by means of the tensioning screws 34, ie its width can be reduced, as a result of which the play between the threads of the threaded hole in the bearing ring and the support screw screwed therein is eliminated.
  • a radial or axial gap 41, 42 is present between the annular first part 7 and the flange 6 on the one hand and the circumference of the receiving part 5 on the other hand. This measure causes an automatic fiber fly removal (Fig. 1).
  • a device for monitoring the width of the gap 9 between the first and second parts 7 and 8 is provided in a row shed weaving machine with such a device.
  • FIG. 1 shows the device in the working position, in which the weaving rotor 2, the receiving part 5, the first part 7, the bearing ring 15, the ring 16 and the clamping ring 20 rotate, while the second part 8 and the piston arrangement stand still.
  • the weft threads are fed in via the stationary second part 8 and inserted into the shed not shown by the rotating first part 7.
  • the device contains a part 7 which rotates with the weaving rotor 2 and has takeover channels 11 for weft feed and a part 8 which is stationary with respect to the weaving rotor 2 and has connecting channels 10 for the weft feed.
  • the parts 7, 8 are arranged axially with respect to one another and held in a working position by energy accumulators 24 such that there is a gap between the first and second parts 7, 8; means being provided for the width of the gap adjust and keep constant.
  • the second part 8 is axially displaceable with respect to the first part 7 and is connected to an actuating device 3 in order to pull the second part 8 into an open position in order to expose the take-over and connecting channels 10, 11 intended for the weft feed.
