Definitions

  • the invention relates to a control device for at least one nozzle of a jet entry loom, in particular for an air entry loom with a traveling field, a main nozzle and auxiliary nozzles arranged along the entry path, the control device having a weft insertion means, e.g. Air, is distributed to the nozzles, a stator and a rotor containing manifold, wherein the rotor contains a feed channel which can be connected to a source of the entry means and the stator has at least one outlet channel which can be periodically communicated with the feed channel and which is connected to the nozzle.
  • a weft insertion means e.g. Air
  • the invention has for its object to provide a control device which is particularly improved in this regard.
  • At least one control element which is connected between the stator and the rotor and is arranged such that it can be adjusted and locked relative to the stator and has at least one passage opening which can be connected upstream of the outlet channel for controlling the supply of the entry means to be introduced from the supply channel into the outlet channel.
  • the invention allows the start and / or the end of the blown air supply to the individual nozzles and, if appropriate, also the duration during which the nozzles blow in each case to be controlled or set in a simple manner.
  • This need exists e.g. when changing from a weft material to be entered into the loom of the machine to another weft material, for example one of higher or lower weight or with a different surface structure and carrying grip, which requires or enables a correspondingly lower or higher entry speed.
  • the operator often has to adjust the start and / or end of the blown air supply and the duration of action of the individual nozzles. This means that weaving operations can be optimally designed, particularly with regard to air consumption.
  • the control device according to FIG. 1 contains a stationary pressure vessel 3 as a stator (cf. also EP patent application 80 105967).
  • a hollow shaft 8 is supported as a rotor, via which compressed air is supplied according to arrow 18.
  • several driver pins are fastened, of which only one is visible in FIG. 1 and is designated by 13.
  • a rotary control slide 14 provided with an elongated slot 15 is carried along by the driving pins 13 (arrow 20).
  • the rotor unit essentially comprises the control slide 14, the hollow shaft 8 and the driver pins 13.
  • the parts 3 and 14 form the beam distributor of the control device, designated as a whole by 10.
  • the segments 51, 52 intermesh like a comb at 61, which creates slots 62 of adjustable size.
  • a slot 62a is in front of an associated connection 63a of a supply line (not shown) for the blown air of an associated nozzle.
  • the connections 63a are, as can be seen from FIG. 1, attached to the pressure vessel 3 on a helical line.
  • the rotor unit 8, 13, 14 rotates in the rhythm of the weaving machine, not shown, so that the compressed air introduced into the hollow shaft at 18 exits into the interior of the pressure vessel 3 via bores 22 made in the hollow shaft (arrows 65).
  • the longitudinal slot 15 of the rotary slide 14 is successively guided over the slots 62a, so that the nozzles connected at 63a are supplied with air one after the other and blow in accordance with the insertion speed of the weft thread or with the advancement of the tip of the weft thread in the shed and onto it Wear the thread through the entire shed.
  • the segment 51 in FIG. 2 must be adjusted in the counterclockwise direction in accordance with arrow 57.
  • the edge 71 in FIG. 2 is shifted to the left, as a result of which the beginning of the blowing is brought to an earlier point in time.
  • the edge 72 of the segment 52 remains at the position shown in FIG. 2. The blowing end of the corresponding nozzle therefore remains at the same time. This will increase the blowing time on the nozzle.
  • edge 72 in FIG. 2 must be moved to the right, i.e. segment 52 must be adjusted clockwise.
  • round bores 74 indicated by broken lines in FIG. 3 are assumed for the escape of air into the lines connected at 63a.
  • oval recesses 75 are arranged in the pressure vessel 3, the adjustment range of the beginning and / or end of blowing as well as the blowing duration for the nozzle in question can be increased.
  • a shaft 8a is mounted in the pressure vessel 3 with the interposition of a seal 112.
  • a disk-shaped rotor 14a is fastened with an air passage slot 15a, which is mounted in the pressure vessel 3 with the interposition of a seal 111.
  • a disc 78 which is mounted on the shaft 8a with the interposition of a seal 113 and is not co-rotating and adjustable via a gear 96. It contains several recesses 82 to 88 to be moved between the bore 15a and the air outflow opening 63c located in the wall 77. In this way, the start of the blow, the end of the blow and the duration of the blow can be set for the respective nozzle.
  • connection 63b e.g. For a ring 3a located outside the shed on the weft side and carrying the main entry nozzle, a bushing 79 is connected.
  • bores 74a are arranged - apart from the bores 74 in front of the slots 62a - through which further connections 63 and associated lines and nozzles can be supplied with air.
  • the helical line 80 indicated in dashed lines in FIG. 3, on which the teeth 92, 93 of the comb-like engagement of the two segments lie, can also be steeper (larger angle between the lines 80, 95 drawn in FIG. 1) or less than * the axis line 95 be steep (smaller angle).
  • the slot 15 of the rotary slide 14 can also run more or less helically and need not be directed parallel to the axis line 95. In this case, the screw shape can be inclined more strongly with respect to the axis line 95 than the screw line 80 or can also have less inclination than this.
  • two segment-like control half-rings 78a, 78b controlling the air jet supply are arranged between the stator 3 and the rotor 14a.
  • the control half rings 78a, b can be pivoted in a circular annular groove 121 of the pressure container 3 by means of the hand lever 54. They can be used to set the start, end and / or duration of the air flow entering at 15a and exiting at 63a.
  • further beam distributors 10 can be arranged on the right on the hollow shaft 8, for example.
  • control elements 78c, d in the form of annular disks are used instead of the control half rings 78a, b. These have teeth 92, 93 with which they intermesh like a comb.
