Definitions

  • the invention relates to a weft insertion device for an air jet loom according to the preamble of claim 1.
  • the Main blowing nozzle block located on the sley via flexible pressure lines supplied with compressed air.
  • the air supply to the individual blowing nozzles takes place via Distribution arrangements, which are fixed to the machine frame and above said Pressure lines are connected to the individual blow nozzles.
  • the pressure lines between the manifold and main blow nozzle block have a certain length, so that the Weblade ensures a trouble-free air supply to the main blow nozzle block.
  • temporarily bending the cross-section of the flexible pressure lines change with every movement of the sley, with each change in cross-section corresponding wear and tear.
  • a system with improved air supply to the main blow nozzle block is in the EP 619 391 B1.
  • the pressure lines between the Manifold block and main blow nozzle block kept short by the manifold block is arranged approximately midway between the end positions of the movement of the sley which sley the main blowing nozzle block performs the swiveling movement. This can the mechanical stress on the lines and the pressure loss are reduced.
  • the invention is therefore based on the object, the weft insertion device for To improve air jet weaving machines of the type described at the beginning.
  • the invention is based on the fact that the distributor block or blocks are arranged so that they the main blowing nozzle block at least partially regardless of the position of the sley surround.
  • the individual distribution blocks that are arranged approximately L-shaped or U-shaped around the main blow nozzle block.
  • the individual manifold blocks in a plane perpendicular to the longitudinal axis of the The sley should be arranged, or spatially in the direction of the longitudinal axis of the sley be offset from each other.
  • the offset arrangement offers, for example, when using a so-called tandem arrangement of pre-nozzle and main nozzle the advantage that both nozzles can be supplied with compressed air via relatively short pressure lines.
  • the distributor block is in the form of a circular arc or U-shaped trained, the outputs at regular or variable intervals to each other on the circular arc or the U-shape of the manifold block.
  • each outlet of the distributor block is a controllable valve assigned so that the air supply to each individual blowing nozzle can be regulated.
  • a main blow nozzle block 2 which several, in the example has a total of eight, single blowing nozzles 3, each in two rows to four nozzles are arranged side by side.
  • Each individual blowing nozzle 3 is assigned an input 4, via which the nozzle is supplied with compressed air. To ensure easy access to the entrances 4, they are to be ensured in a suitable manner over the scope of the Main blowing nozzle block 2 arranged distributed.
  • the main blow nozzle block 2 is fixed by means of connecting elements, not shown connected to the sley 5, which is only indicated schematically here.
  • the weaving machine moves the sley 5 alternately between the longitudinal axis 6 two end positions 8.9, namely between the weft insertion position 8 and Weft stop position 9 back and forth.
  • the direction of movement is through the Double arrow 7 indicated.
  • the drawer 5 together with the drawer 5, the also moves Main blow nozzle block 2 between the end positions 8, 9 back and forth.
  • the weft insertion device 1 further comprises a plurality of distributor blocks 10, 13 and 16, which is approximately U-shaped outside the working area of the sley 5 Main blow nozzle block 2 are arranged. Through these distribution blocks 10, 13, 16 are the individual blowing nozzles 3 are supplied with compressed air.
  • Each manifold block 10, 13, 16 has a main air supply 11, 14 and 17 through which it is supplied with compressed air.
  • the compressed air flows in a channel inside the Distribution block 10, 13, 16 and is distributed to several outputs 12, 15 and 18.
  • everyone Output 12, 15, 18 is via a valve, e.g. a solenoid valve, individually controllable.
  • the outputs 12, 15, 18 of the distributor blocks 10, 13, 16 are in one Row arranged side by side.
  • two-row arrangements are also conceivable.
  • each inlet 4 of the individual blowing nozzles 3 is provided by that Distribution block supplied, the output of which is as direct as possible to the inlet of the nozzle opposite, i.e. the inputs 4 in the upper area of the main blow nozzle block 2 are supplied by the upper manifold block 13 while e.g. inputs 4 in the left Area of the main blow nozzle block 2 are supplied by the left manifold block 10.
  • the length of the pressure lines 19 can be kept very short the length dimensioning on the corresponding distributor block 10, 13, 16 distant end position 8 or 9 of the sley 5 oriented.
  • a so-called tandem nozzle arrangement consisting of a pre-nozzle 29 and a main nozzle 28, it is advantageous to the individual Distribution blocks 30, 31 spatially offset in the direction of the longitudinal axis 6 of the sley 5 to arrange.
  • the distributor block 30 serves to supply the pre-nozzle 29 and Manifold block 31 for supplying the main nozzle 28. So the length of each Pressure lines 32 are kept short. It can also be provided a further Manifold block opposite manifold block 31 directly next to blowing nozzles 28, 29 to be arranged, in such a way as shown in Figure 1.
  • FIG. 2 shows a further embodiment of the weft insertion device.
  • a distributor block 20 is used, which is in the form of an arc around the Main blow nozzle block 2 is arranged.
  • the distributor block 20 has a main air supply 21.
  • the distributor block 20 distributes the compressed air supplied to several outlets 22 which preferably at regular intervals on the one through the manifold block 20 formed arc are arranged. So there are 4 for each input Single blow nozzles 3 of the main blow nozzle block 2 at least one outlet 22 of the Distribution block 20, the input 4 in one of the two end positions 8.9 Weblade 5 is closest.
  • Exactly this output 22 is preferably via a flexible pressure line 23 with the assigned inlet 4 of the single blowing nozzle 3 connected. As a result, the length of the pressure lines 23 can be kept very short, with the length dimensioning in turn depending on the one chosen Exit 22 distant end position 8 or 9 of the sley 5 oriented.
  • FIG 3 is another embodiment of the weft insertion device shown.
  • a single manifold block 24 which is from a main air supply 25 is fed and consists of several interconnected individual elements. This results in an approximately circular arc-shaped design of the distributor block 24 reached.
  • the outputs 26 for supplying air to the main blow nozzle block 2 can arbitrarily and appropriately distributed over the individual elements.
  • upper area of the distributor block 24 four outputs 26 and in the two Side areas two exits 26 are provided.
