Definitions

  • the invention relates to a metering device for the weft thread of a weaving machine with a metering roller, which lies between a supply unit and a take-off unit and which is wound around the weft thread in metering operation and determines the pulling speed of the weft thread.
  • Metering devices and thread take-off devices for weft threads have long been used in various types of weaving machines.
  • DE-A-25 45 476 shows a device for delivering yarn to a weaving machine, which has a metering roller for the pulling-off speed of the weft thread and a downstream thread store.
  • FR-A-2 190 962 shows a metering device which, in addition to the device according to DE-A-25 45 476, has a shooting nozzle and a catching nozzle on a shooting axis which is parallel to a tangent but in one plane in a plane approximately perpendicular to the roll axis of the metering roll Minimum distance the metering roller crosses.
  • the invention takes this fact into account. On the one hand, it has the task of automatically feeding new spools or interruptions in the weft, and inevitably a new weft into one for weaving to bring the intended starting position, as well as to deliver the weft to the weaving machine in a coordinated manner.
  • this object is achieved in that a catch nose is installed near the circumferential surface of the metering roller and can be rotated in a controlled manner about the roller axis, and in that the weft thread enters a catch area of the catch nose via a controlled relative movement between a weft thread lying in the insertion axis and the catch nose is displaceable with the purpose of wrapping the metering roll with a certain number of turns.
  • the advantage of the invention is that a higher availability of the weaving machine arises when certain types of interruptions in the weft thread are automatically remedied when they arise or at the command of the operating personnel.
  • the dependent claims 2 to 17 relate to advantageous developments of the invention, while in independent claim 18 the use of the invention in row shed looms is claimed as an advantage.
  • metering devices 1 for the weft thread 2 of a weaving machine are shown.
  • a multiply wrapped metering roller 3 which lies between a supply unit 10 and a take-off unit 20, determines the pull-off speed of the weft thread 2, the rotational movement of the metering roller being matched to the weaving cycle.
  • sensors respond, e.g. in the event of an interruption in the metering area, the sensors 35 and / or 51 and give a signal to a controller 33 which, on the one hand, stops the weaving machine, frees it from thread remnants and brings it into a starting position, and, on the other hand, automatically threading a weft thread 2 into one Start position causes.
  • the control 33 With the threading of the weft thread 2, the multiple wrapping of the metering roller 3 and the transfer of a thread start to a weft preparation 50 are linked by the control 33.
  • the weft thread 2 is drawn off from a supply spool 38 and, viewed in the conveying direction, runs over an eyelet 37, through a suction nozzle 14, through a brake 12, past a sensor 35 for thread interruption, through a shooting nozzle 11 on a metering roller 3.
  • the thread 2 runs through a catch nozzle 21 and pulling element 24, past a sensor 51 for thread interruption into a transport nozzle 52 of the weft preparation 50.
  • the weft thread 2 is braked on the brake 12 with an adjustable force and runs under tension on the metering roller 3.
  • a pull-off element 24 shows a nozzle which exerts so much tension on the weft thread 2 that the rope friction in the winding direction 41 rotating metering roller 3 is sufficient to convey the thread at a certain peripheral speed against the pulling reaction force and against the friction in the elements between the supply spool 38 and metering roller 3.
  • its outer surface is designed as a conical outer surface 32 as in FIG. 7 or, as in FIGS. 2, 4, 5, 6, 8, 9, by a guide pin 30 which is directed toward the roller axis 5 has an angle ⁇ 7 °, supported.
  • the brake 12 With a shooting command, the brake 12 is opened pneumatically and the suction nozzle 14, the shooting nozzle 11 and the catching nozzle 21 with the pulling element 24 are actuated for predetermined time intervals in order to pass the beginning of the thread caused by the thread break along the shooting axis 4 from the suction nozzle 14 to the shooting nozzle 11, past the To shoot the outer surface of the metering roller to the catch nozzle 21 and further via the pulling element 24, which consists of a nozzle extension, into the deflection device 22. If, as previously assumed, there is still thread in the suction nozzle 14, the sensor 35 now indicates the presence of thread.
  • the shoot-in command is first reversed and then the old supply spool 38 is pivoted away about a pivot axis 58 by a pivoting device 53, as can be seen in FIG. 3, and a new supply spool 38 is pivoted toward the suction nozzle 14 on a pivoting arm 59.
  • the swivel arm 59 extends laterally past the supply spool 38 in order to limit the pull-off balloon, and ends once in an eyelet 37 through which the thread start 15 of the new supply spool is guided and on the other hand in a weakly acting thread clamp 19 which prevents the overhanging Thread beginning 15 parallel to a slot 13 of the suction nozzle 14 for suction and shooting.
  • the shooting-in axis 4 lies approximately in a plane perpendicular to the roller axis 5 and at a minimum distance from the lateral surface of the metering roller 3.
  • the minimum distance from the lateral surface is so large that the air jet of the injection nozzle 11 is deflected only insignificantly by the curvature of the lateral surface.
  • the air flow and weft thread 26 are deflected to a thread store 23 until the brake 12 closes, while the catch nozzle 21 with the pulling element 24 remains exposed to air. There is no further thread transport because the braking force of Brake 12 is stronger than the pulling force of pulling element 24.
  • a deflection element 9 now executes a rotary movement in the vicinity of the catch 6 and moves an edge 7 of a pin arranged transversely to the insertion axis 4 into the insertion axis 4 and deflects the weft thread 2 further into a catching region 8 with a controlled relative movement 40 the catch nose 6.
  • the metering roller 3 is rotated by the rotary motor 17 through a whole number of turns in the winding direction 41 and at the start of each turn the catch nose 6 crosses the deflected weft thread 2 in its catch area 8 and takes it in the form of a loop.
  • the weft thread 2 is taken along by the catch 6 against the pulling action of the pulling element 24, the thread being pulled backwards out of the thread store 23 until the rope friction on the metering roller 3 is sufficient to pull the thread through the brake 12 from the supply spool 38 deduct.
  • the catch nose 6 approaches the shooting axis 4 during its revolutions with the retracted thread loop, the thread drawn on the front side of the metering roller 3 by the catch nozzle 21 jumps back over the edge 28 of the metering roller onto its outer surface.
  • the deflection element 9 is actuated.
  • the wrapping movements of the metering roller 3 are interrupted in the starting position of the catch 6 and the deflection element 9 swings back into its starting position and releases the thread running to the catch nozzle 21.
  • the metering roll is wrapped and the weft thread is tensioned into the thread store 23.
  • a new weft thread tip is generated, the position of which is given by the location of the separating element 25.
  • the cut end of the thread disappears in the thread store 23 and the deflection device 22 moves back into its starting position and clears the way to the transport nozzle 52.
  • the new weft thread tip is brought into a starting position for the next weaving cycle by a targeted rotation of the metering roller 3 by a predetermined angle, the presence of the weft thread having to be confirmed by the sensor 51.
  • An air deflection element 39 is shown in FIG. 4 as a further deflection element, which deflects the weft thread 2 in the form of an arc from the insertion axis 4 into the catch area 8 of the catch nose 6.
  • a pivotable eyelet 36 is shown with a rest position in the insertion axis, through which the weft thread is also inserted and which swings the weft thread from the insertion axis 4 into the catch area 8 of the catch nose 6.
  • a continuous edge 28 of the metering roller 3 is shown, in which a pin 46 is inserted as a catch 6, which forms with its axis an angle with the vertical of its base 47 on the roller axis 5, which is less than 60 °. Part of the slope of pin 46 is in the wrap direction 41 to secure the thread to be able to take over.
  • a catch 6, which is formed by a recess in the edge 28 of the metering roller the imbalance is smaller, the mass of the pin is easier to ascertain and the imbalance can be easily compensated for high metering speeds.
  • FIGS. 2 and 8 show a modified system for generating a relative movement 40 between the weft thread 2 in the weft axis 4 and a catch nose which is designed as a flyer hook 29 which also rotates at times and which is plugged onto the metering roller 3 for wrapping and with the wrapping Crossing axis crosses.
  • the catch area is moved to the weft.
  • a holder 31, which is positively rounded toward the edge of the metering roller 3, is axially immersed in the metering roller 3 and anchored with permanent magnets 43 by adhesive action.
  • the magnetic flux is bundled in the holder 31 by pole bridges 44 and in the metering roller 3 by a soft iron ring 42.
  • the flyer hook 29 moves axially to the metering roller 3 above the insertion axis 4 into a starting position in which the weft thread 2 is covered by the flyer hook 29. This starting position of the flyer hook 29 is monitored by a sensor 34. As shown in FIG. 8, the flyer hook itself is bent in a z-shape in one plane through the roller axis, the elongated upper leg covering the weft thread 2 that has been shot in.
  • the flyer hook 28 is again in the starting position, which is monitored by sensor 34, while the thread in the form of a loop from the shooting nozzle 11 circles the metering roller 3 and the guide pin 30 and runs into the catching nozzle 21.
  • the flyer hook 29 also covers the thread running from the metering roller 3 to the catching nozzle 21, so that the wrapping process can be repeated.
  • the holder 31 together with the flyer hook 29 is withdrawn axially to the roller axis 5 against the holding forces of the permanent magnets 43 by the previous feed movement 40, so that a safety distance to the metering roller 3 and the thread path is achieved, which will later enable a high-speed metering operation the metering roller 3 enables.
  • the holder 31 In the non-attached state, the holder 31 is supported on a transfer arm 60, while in the attached state the connection to the transfer arm 60 is interrupted so that the thread can cross the end face of the metering roller 3 when it is wrapped.
  • a transfer arm is shown in Fig. 8, which is displaceable with its longitudinal axis in the roller axis 5 and is embedded in the radial three cylindrical cams which protrude under pressure from springs 62 and which can also be pressurized via a compressed air connection 63.
  • the cylindrical cams 61 are pressurized with compressed air and rest in a holding groove 64.
  • the compressed air connection 63 is vented.
  • the transfer arm 60 is withdrawn from the holder 31 and during the extraction the cams 61 slide against the spring force out of the holding groove 64 and generate an axial force against the magnetic holding forces. This axial force is somewhat higher than the forces required for entrainment when wrapping. If the sensor 34 continues to signal the presence of the flyer hook 29 while the transfer arm is being pulled out, the magnetic forces checked in this way are considered sufficient for the wrapping.
  • the transfer arm 60 moves into the holder 31, the cams 61 initially only engaging in the holding groove 64 under pressure from the springs 62.
  • the cams 61 are pressed so firmly in the holding groove that the holder 31 can be pulled out of the metering roller 3 against the magnetic forces, which is confirmed by sensor 34.
  • the cylinder cams 61 are limited by a ring 65 with a bayonet lock and by screws 27 in their radial movement to the outside. According to the extension length of the cylinder cam 61, the receiving bore of the holder 31 is provided with a conical inlet.
  • a central controller 55 coordinates the operating states and processes of various functional groups 50, 54, 56, 57, the functional group 50 comprising elements, such as sensors and actuators, for the shot preparation, the functional group 54 elements for the operation and automatic threading of the metering device 1
  • Function group 56 which includes web elements and function group 57 elements for troubleshooting.
