Definitions

  • the invention relates to a pneumatic weaving machine Weft thread entry according to the preamble of Claim 1.
  • the object of the invention is a weaving machine with pneumatic shot insertion so that the disadvantages mentioned do not occur.
  • the advantage achievable with the invention is in essential to see that up to sixteen Weft threads of different types and colors applied can be.
  • the weaving machine in question contains a Machine frame 1, a warp beam 2 from the warp threads 3.4 can be drained, a match tree 5, a Shed forming device 6, an arrangement 7 for entry of weft threads, a reed 8, a goods deduction 9 and a goods tree 10.
  • the shedding device 6 forms via healds an upper and lower compartment 11, 12 with the Warp threads 3.4.
  • the arrangement 7 contains one pneumatic weft insertion device 14 and a Scissors 15, a thread clamp 16 and a blowing aid 17, in the direction of the thread between the insertion device 14 and the reed 8 are arranged.
  • the Entry device 14 is mounted on the machine frame 1.
  • the scissors 15 and the thread clamp 16 are with the Reed 8 coupled.
  • the blowing aid 17 is with the Webblatt 8 connected.
  • the entry device 14 contains a support part 21, eight Blow nozzles 22, a nozzle block 23, a holder 24 and an actuator 25.
  • the support member 21 is attached to the machine frame 1 by means of screws 26.
  • the Blow nozzles 22 are arranged in pairs and stand with a compressed air source and a weft store in Active connection.
  • the blowing nozzles 22 are in the nozzle block 23 detachably mounted on one side.
  • the holder 24 for the Nozzle block is connected to the support part 21.
  • the Actuator 25 is via a kinematic Organ 27 connected to the shedding device 6 to the Blower nozzles 22 to put in the bullet position.
  • nozzle block 23 and the holder 24 are configured such that the mouth of the blow nozzles at right angles to each other extending directions are pivotable. It is a feather 28 provided which the kinematic organ 27 under Tension holds. It should be noted that instead the actuator 25 a drive assembly can be provided, which is known per se Control device is driven to in the blow nozzles to put the entry position.
  • the reed 8 is on one Sheet bar 31 mounted. There is one on the sheet bar Thread guide device 32 attached. It's from Advantage if the guide device 32 a Air supply part 33, which is mounted on the sheet bar is a plurality of fins 34 that are comb-like arranged and each provided with a recess 35 are to determine a guide channel 36 and Relay nozzles 37 contains to the registered To promote weft 38 through the guide channel. Instead of the thread guide device 32, a so-called tunnel reed with relay nozzles applied become.
  • the blowing aid 17 is a plate-shaped body 41 with a conical Penetration 42 and with an outlet slot 43.
  • the Body 41 is attached to the air guide part 33. It however, the first lamella 34 is possible as a blowing aid train (Fig. 4).
  • the thread clamp 16 has a clamping finger 45 and one Clamping jaws 46, each with a plate 47 for Holding the weft are provided.
  • the clamping finger is articulated on an axis 48 which is on the machine frame 1 is arranged.
  • the jaws 46 is directly with the Webblatt 7 and / or the drawer connected. Further is a return spring 49 is provided for the clamping finger, the one hand on the machine frame 1 and the other rests on the clamping finger.
  • a Stop part 50 mounted to the position of the Pinch fingers (Fig. 5).
  • the scissors 15 have a fixed and a movable Scissors blade 51.52.
  • the stationary scissor blade 51 is on Machine frame 1 attached.
  • the movable scissor blade 52 is mounted on the reed 8 (Fig. 6).
  • FIG. 7 shows the assignment of the blow nozzles to the through the slats 34 determined guide channel 36.
  • Ein essential feature of the weaving machine is that the respective pair of blow nozzles essentially parallel is aligned with the center line of the guide channel 36, when the guide channel takes the entry position.
  • the Adjustment of the blowing nozzles 22 takes place through the Actuator 25 and the kinematic element 27.
  • the blow nozzle 12 can be bundled to be ordered.
  • the shedding device 6 comprises e.g. a jacquard or dobby, one Color control device 56, a summing gear 57 and a one-armed lever 58, which on the machine frame 1 is articulated.
  • a summing gear and their Function are known, so on a description the same is waived.
  • the entry process is described below with reference to FIGS. 9 to 12 described.
  • the Main drive shaft of the loom a weft registered and posted. From this machine cycle is the control of the individual elements of the loom derived.
  • the weaving machine described above is generally the drive of the reed 8 and related on the weft entry only the setting of the Blower nozzle 22 to the entry position and the entry of the weft thread 38 as a function of the angle of rotation of the Main shaft driven during the time of the Clamping and severing the weft 38 by the design or functional assignment of the scissors and the thread clamp to the reed 8 is determined. This has the particular advantage that the control is simplified.
  • Fig. 9 shows the situation during the entry a weft 38.
  • the blowing nozzle 22 is in the Entry position provided.
  • the reed 8 is in the retracted position, the scissors 15 and the Thread clamp 16 are in the open position and Weft thread is through the blowing aid 17 in the Guide channel 36 of the thread guide device 32 shot in.
  • the weft 38 is cut, because the scissor blade 52 connected to the reed 8 is moved against the stationary scissor blade 51. Thereby a new weft thread is provided for insertion. After cutting, the weft 38 is through the Thread clamp 16 moves synchronously with the reed 8 (Fig.11).
