Definitions

  • the invention relates to an air feed block for a loom according to the preamble of claim 1.
  • An air supply block of the type mentioned is from the WO 97/29231 known.
  • the air supply block is disposed between a compressed air supply means and a pair of main blowing nozzles which insert a weft yarn into a shed.
  • the known air supply block includes an input connected to the compressed air supply and an output connected to the pair of main blowing nozzles.
  • the input and output are connected to each other by means of existing channels in the air supply block, wherein in the air supply block, a switchable closing valve and an adjustable throttle valve are integrated. If a weaving machine is to process a larger number of different weft threads, then a correspondingly large number of pairs of main blowing nozzles and also a correspondingly large number of air feed blocks are required.
  • the invention has for its object to form a Lucaszu 1500block of the type mentioned so that a relatively large number of Hauptblasdüsen can be supplied with compressed air without a very large space is required for the compressed air supply.
  • This object is achieved in that two outputs are provided on a longitudinal side of a substantially cuboid base body, each of which own switchable and adjustable valves are assigned.
  • the invention offers the advantage that two sets of main blowing nozzles can be supplied with compressed air by means of an air feed block, so that the required space is relatively low.
  • Such Heilzu Industriesblöcke are particularly well suited for use in air jet looms, in which several different weft threads are processed.
  • the main body is free of inputs, outputs and valve actuators on two opposite longitudinal sides. This makes it possible to mount the Heilzu Fightingblöcke close together, so that the space requirement can be further reduced.
  • the one or more inputs, the channels and the outputs are arranged substantially in a common longitudinal plane of the base body. In this way, the width of the body of the BeerzuGermanblockes can be limited in the transverse direction, so that then a relatively large number of such Gutzu Foodblöcke can be accommodated in a relatively small space.
  • the air supply block 1 contains channels 8, 9 and 10, which connect the input 2 to the output 5. Similarly, channels 11, 12 and 13 connect the input 3 to the output 6.
  • a switchable closing valve 14 and an adjustable throttle valve 15 are arranged in the connection between the input 2 and the output 5.
  • a switchable closing valve 16 and an adjustable throttle valve 17 are arranged between the input 3 and the output 6.
  • the two inputs 2 and 3, the two outputs 5 and 6 and the channels 8 to 12 are arranged substantially in a longitudinal plane 24 of the feed block 1.
  • This longitudinal plane 24 is perpendicular to the said longitudinal sides 4 and 7.
  • the two outputs 5 and 6 are at a smaller distance With respect to a perpendicular to the longitudinal sides 4, 7 in the longitudinal plane 24 extending center 25 of the input 2, the output 5 and the channels 8, 9 and 10 are mirror-symmetrical to the input 3, the output 6 and the channels 11, 11 and 13.
  • the channels 8 to 13, for example, in the air supply block 1 incorporated holes.
  • valve drives 20 of the two switchable closing valves 14 and 16 are located on the longitudinal side 4 of the main body between the inputs 2 and 3. They are also in the already mentioned longitudinal plane 24 and are also arranged mirror-symmetrically to the center 25.
  • the switchable closing valves 14, 16 are each assigned a valve seat 26 which belongs to the channel 9 or 12.
  • a valve stem 18 is pressed against the valve seat 26 by means of a spring 19 in order to shut off the connection between an input 2 or 3 and an output 5 or 6.
  • an electromagnet which is associated with the valve stem 18 and lifts off the valve seat 26 to open the valve.
  • the valve tappets 18 of the closing valves 14 and 16 are each in the extension of the associated output 5 and 6 and parallel to each other.
  • the adjustable throttle valves 15 and 17 each have a spindle 21 which is axially adjustable by means of a linear motor 22.
  • the end 23 of the spindle 21 protrudes into the respective channel 10 and 13.
  • the throttle valves 15 and 17 and in particular the spindles 21 are also in the already mentioned longitudinal plane 24 and are also arranged mirror-symmetrically with respect to the center 25.
  • an electrical connector 31 On the housing of the linear motor 22 of the throttle valve 17, an electrical connector 31 is arranged. Of the connector 31 lead electrical lines 32, 33, 34, 35 to the closing valves 14, 16 and the throttle valves 15, 17. To the connector 31, a non-illustrated electrical cable is connected, which leads to a control unit of the loom.
  • the use of only one connector 31 for both closing valves 14, 16 and both throttle valves 15, 17 is for the assembly of the air supply block 1 together with the associated parts on a loom and for the attachment of the required electrical connections of advantage.
  • the electrical lines 32, 33 and 34 are laid in a longitudinal groove 38, which is provided in the top side forming the upper side 7.
  • the lines 32 and 33 are each guided through a bore 36 and 37 of the air supply block to the valve actuators 20 of the switching valves 14, 16.
  • a plurality of Lucaszu Fightingblöcke 1 are each secured with screws 28 on a compressed air tank 27.
  • the compressed air tank 27 is provided in its center with a groove-like depression into which the valve actuators 20 of the switching valves 14 and 16 protrude. Laterally of this groove-like depression of the compressed air tank 27 has a plurality of outputs 29, 30, to which the inputs 2, 3 of an air supply block 1 connect.
  • four air supply blocks 1 are mounted on the compressed air tank 27.
  • the outputs 29 and 30, in the area no air supply block 1 is mounted, are closed with plugs 43.
  • sealing means are provided which prevent leakage of compressed air from the feed block 1 in this area.
  • screws 66 are also provided to fasten the valve drives 20, 22 to the air supply block 1.
  • plugs 39, 40 are provided in the drilled channels 8 and 11 are at the unused ends plugs 39, 40 are provided.
  • the outputs 5, 6 are provided with only schematically illustrated terminals 41, 42 which are glued, for example, to the air supply block 1. These ports 41, 42 serve to connect lines which lead to one or a pair of main blowing nozzles connected in series.
  • terminals 41, 42 are provided, which are screwed with threaded projections in corresponding threads of the outputs 5, 6.
  • an air supply block 1 can be relative to create small width B in the transverse direction, so that a compact arrangement of several such air supply blocks 1 is possible.
  • the air supply blocks 1 with two outputs 5, 6 and associated valves are particularly suitable for use with an air jet loom.
  • air jet looms it is advantageous to provide main jet nozzles in even numbers, since the same type of weft yarn is supplied, for example, by two bobbins and thus by two main blowing nozzles or two pairs of cascaded main blowing nozzles according to the disclosure of US Pat WO 97/29231 is entered in a shed. If, however, an odd number of outputs should be desired, then it is readily possible to close one of the outputs 5 or 6 with a stopper.
  • the controller can be designed so that the associated closing valve 14 or 16 remains permanently closed.
  • the outputs 5 and 6 are arranged at a distance from one another, which coincides, for example, with the distance from inlets to main blowing nozzles, as for example in the non-prepublished Belgian patent application BE 9700465 corresponding to WO 98/54385 the applicant is disclosed.
  • the air supply blocks 1 are particularly suitable for use with main jet devices as disclosed in said Belgian or International patent application.
  • bores 44, 45 are connected to the outlets 5, 6, which in turn are connected to bores 46, 47 leading to the longitudinal side 7.
  • the holes 44 and 46 are with respect to the center 25 mirror-symmetrical to the holes 45 and 47.
  • the ends of the holes 44 and 45 are closed by means of plugs 48, 49.
  • the holes 44 to 47 are also located substantially in the longitudinal plane 24 of the air supply block 1.
  • the bores 46 and 47 are provided with terminals 50, 51 for lines not shown, which are glued, for example, to the air supply block 1.
  • compressed air at relatively low pressure can be supplied via bores 46 and 47, which then flows via bores 44 or 45 to exit 5 or 6.
  • a pressure sensor can also be attached to the bores 46 or 47 in order to measure the pressure of the compressed air flowing out of the air supply block 1.
  • Fig. 5 and 6 a modified embodiment similar to Fig. 4 is shown, in which to the output 5 bores 52, 53 and 54 are guided, wherein the bores 52 and 53 are closed at their ends with plugs 55, 56.
  • the bores 52, 53, 54 are slightly outside the mentioned longitudinal plane 24. However, since they have relatively small dimensions, they have little influence on the overall width B of the air supply block 1. This width is substantially by the valve trains and / or the seats 26th the closing valves 14, 16 determines.
  • the air supply block 1 contains only one input 72 for compressed air, which is located in the longitudinal plane 24 of the air supply block 1.
  • This input 72 is connected to a located in a side wall of the channel-shaped recess of the compressed air tank 72 output 76.
  • the input 72 is connected via channels 74, 8, 9 and 10 to the output 5 and via channels 74, 8, 9, 75, 12 and 13 to the output 6.
  • the channel 75 in this case connects the channels 9 and 12.
  • the channel 74 connects the input 72 with the channel 8.
  • the end of the channel 74 is closed with a stopper 77.
