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.
  • the main disadvantage of this device is that the contacting sealing surfaces result in greater wear and tear, and the existing sealing surfaces do not meet the requirements, so that the weft threads are not transferred properly.
  • 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 4.
  • 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 includes a ring-shaped first part 7 fastened to the flange and co-rotating with the weaving rotor 2 and a ring-shaped 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 a gap 9 between the two opposite end faces is present to avoid friction between them.
  • 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).
  • a radial and axial recess 41 and 42 are 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).
  • 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 on 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 clamping screws 34, i.e. whose width can be reduced, whereby the game between the threads of the threaded hole in the bearing ring and the support screw screwed therein is canceled.
  • This measure advantageously ensures, on the one hand, that the gap 9 is correctly and precisely set with respect to the gap width and the plane parallelism between the first and second parts 7, 8, and on the other hand that the support screw 33 is fixed and secured.
  • the second part 8 is rotatably mounted on the receiving part 5 via an actuating device 3.
  • 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 and secured against rotation 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 to the bearing
  • the actuating device 3 has a piston arrangement with a housing part 25 and a piston 26.
  • the housing part 25 is essentially a hollow 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 slidably 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 lie sealingly on the inner surfaces of the partial sections and form with the shoulder an annular working chamber into which the inlet channel 29 opens.
  • 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 loom with such a device, which is shown in FIG. 3.
  • a sensor nozzle 43 is arranged in the stationary part 8, which is fed with air.
  • a change in the width of the gap 9 causes a change in the dynamic pressure.
  • a change in the dynamic pressure causes the differential pressure switches to switch over at certain pressure values and to trigger electrical signals.
  • 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. Between the first and second parts 7, 8 three support units 30 are provided, one Form three-point support and keep the first and second parts 7, 8 at a distance to form a gap 9.
