Definitions

  • the invention relates to a rapier weaving machine with a device for guiding and Storage of a flexible gripper support member (divisional application from EP 0 866 156 A1).
  • An essential feature of the invention according to claim 1 is that the gripper belt of a first and at least a second pneumatic slide bearing (device) and stored, which has an improved effectiveness compared to the known solutions of the pneumatic fluid unfolded on the gripper belt.
  • the air bearing is therefore both in the area of the drive wheel and outside arranged and acts on the gripper belt from above, e.g. also taking off counteract the gripper belt from the drive wheel.
  • the air bearing according to the invention is also suitable for lateral guidance of the gripper belt by the air bearing is designed so that it also encloses the side region of the gripper belt and between an air cushion to the bearing body and the right and left side wall of the gripper belt trains the side of the rapier belt outside the shed.
  • the air bearing consists of a bearing rocker arranged in the longitudinal direction of the gripper belt, which is movably mounted at a pivot point.
  • the bearing rocker enables it to inevitably track itself in the event of vertical movements of the gripper belt during the alternating back and forth movement in the horizontal plane.
  • the bearing rocker has an air channel which is closed at the end and which is connected to a compressed air connection.
  • the actual storage is carried out by an elongated bearing strip, which is adapted in length to the rocker and has the cross bores which correspond in number and position to the cross bores in the rocker.
  • the bearing bracket is firmly connected to the bearing rocker by connecting means so that all transverse bores are aligned with one another and compressed air can escape from the bearing bracket via the bores mentioned in the bearing bracket.
  • the outputs of the transverse bores are Bearing ledge expanded to so-called air pockets, which have a larger cross section than the cross holes in the area of the air inlet.
  • air pockets With the help of the air pockets one can homogeneous and stable air cushion between the plain bearing (bearing block) and the e.g. Not Form the perforated surface of the gripper belt.
  • the gripper belt is open with almost no friction loss led its outer surface. Another positive effect is that both the air the bearing itself, as well as the gripper belt cools in the engagement area of the drive wheel.
  • the air bearing can be kept constantly at a constant Air pressure are applied.
  • the pneumatic bearing via the weaving machine control air is supplied in a controlled manner and consequently only in the movement phases of the bearing Gripper belt builds an air cushion. This is done by the machine control Pressure valves controlled, the air pressure and the air volume individually for each Movement phase of the gripper belt can be controlled.
  • the cross bores in the rocker are provided with a thread in order to equip the cross bores with so-called screw-in nozzles.
  • the air pockets in the bearing ledge are designed to be somewhat deeper so that the screw-in nozzles, which have at least one air guiding channel, can be screwed through the air pockets into the thread of the transverse bores provided in the rocker.
  • the bearing rocker and the bearing rail are connected to each other mechanically and air-conducting by the screw-in nozzles.
  • screw-in nozzles instead of cross holes designed as air nozzles has the advantage that cleaning and maintenance of the screw-in nozzles is easier because clogged screw-in nozzles quickly replaced with functional screw-in nozzles can be. Furthermore, a firm and above all airtight connection between Bearing rocker and bearing ledge guaranteed, since each screw-in nozzle is also used as Connecting element works.
  • the bearing material especially the material of the bearing block, must be together with the Material for the gripper belt have good sliding and emergency running properties (e.g. at Drop in air pressure), as well as sufficient wear, running-in and embedding behavior have.
  • a suitable one Material for the bearing ledge is therefore e.g. Copper.
  • the rocker is preferably made of Light alloy.
  • gripper belts In weaving machines, in addition to so-called gripper bars, are used as gripper support members and gripper belts as gripper support members.
  • a gripper belt 21 is shown schematically in FIGS. 1 and 2. In the retracted state, the gripper belt 21 wraps around almost the entire circumference of the drive wheel 22 and is moved into and out of a shed by the alternating rotary movement of the drive wheel 22 in the directions of the double arrow 27.
  • a known type of storage in the prior art is the storage of the gripper belt by means of a combination of rollers 24 and a guide belt 23. This guide belt 23 guides the gripper belt 21 over a large area of the drive wheel 22 and prevents it from lifting off.
  • EP 0 866 156 A1 can now also be used with a gripper belt with a gripper, as shown schematically in FIG.
  • the air bearing 25 is designed such that it follows the circumference of the drive wheel 22 over a wide range, the gripper belt 21 being received and guided between the drive wheel 22 and the air bearing 25.
  • the shape of the air bearing 25 thus follows the contour of the wound gripper belt 21, the structure and mode of operation of the air bearing corresponding to the exemplary embodiments described below.
  • the large amount of friction lost with the gripper belts and the necessary drive torque can be significantly reduced by the air bearing.
  • FIGS 1 to 6 show air bearings in different views and embodiments.
  • the gripper belt 21 carries a gripper 14 at its front end.
  • the gripper belt 21 is driven by a drive wheel 22.
  • Pneumatic slide bearing 25 designed according to the invention is arranged.
  • the pneumatic bearing 25 comprises gem.
  • Figure 3 shows a rocker 1, which by means of a Bearing pin 3 is pivotally mounted about the central axis 3a of the bearing pin 3.
  • the Bearing pin 3 is received in an existing bearing bush 4 in the rocker 1.
  • the pivotable mounting of the rocker 1 is necessary to adjust the vertical To enable gripper belt opposite the drive wheel 22.
  • the bearing rocker 1 includes an air duct 5 which is closed at the end and which is connected to a Compressed air connection 2 is connected.
  • the bearing rocker 1 is connected to a bearing block 8.
  • the width and length of the bearing strip 8 corresponds approximately to the dimensions of the bearing rocker 1 on the output side of the transverse bores 6.
  • transverse bores 9 are provided, the number and position of which corresponds to the transverse bores 6 in the bearing rocker 1.
  • the bearing rocker 1 and the bearing bracket 8 are firmly but releasably connected to one another, for example by means of connecting screws 7, in such a way that the corresponding holes 6, 9 of the bearing bracket 1 and the bearing bracket 8 are aligned with one another.
  • the compressed air can flow out through the transverse bores 6, 9 of the bearing rocker 1 and the bearing rail 8 in the direction of the gripper belt 21.
  • the bearing bar 8 lies against the gripper belt in such a way that an air cushion is formed between the bearing bar 8 and the gripper belt 21.
  • the cross holes 9 are Bearing ledge 8 expanded to air pockets 10 on its side facing gripper belt 21.
  • the air cushion thus forms over the entire upper width of the non-perforated Areas of the gripper belt 21 selectively.
  • the bearing rocker 1 is fixed to the machine by means of the bearing pin 3.
  • the air supply and quantity can advantageously be achieved by means of the weaving machine control 16 and the valves 17 of the bearing rocker 1 are supplied in a controlled manner become.
  • the compressed air flows e.g. from a pressure source 18 via a compressed air line 18a to one or more valves 17, the function of which via electrical control lines 19 from the weaving machine control 16 is influenced.
  • the supplied to the rocker 1 controlled Compressed air flows via a compressed air line 20 to the compressed air connection 2 of the bearing rocker 1. This means that the quantity and time of the compressed air supply to the rocker arm 1 determine depending on whether and how many of the valves 17 are controlled.
  • a simplified way of supplying compressed air provides for the air bearing to be continuously supplied with compressed air pressurized under constant pressure. A complex control of the compressed air supply is unnecessary in this case.
  • FIG. 3 shows an enlarged view of a bearing rocker from FIG. 2.
  • the cross bores 9 of the bearing ledge 8, which are in air pockets 10, can clearly be seen end up.
  • the cross bores 6 of the bearing rocker 1 can be provided with a thread into which a screw-in nozzle 11 provided with at least one air guide channel 26 (see FIG. 4) is screwed.
  • the screw-in nozzles here take over the air line and the connection between bearing rocker 1 and bearing block 8.
  • the air pockets 10 are designed somewhat lower than in the first exemplary embodiment.
  • the heads of the screw-in nozzles 11 are completely accommodated in the transverse bores 9, the air pockets 10 still being present in order to ensure the function of the air pockets.
  • the use of screw-in nozzles 11 enables easier cleaning and maintenance of the air bearing in comparison to the first exemplary embodiment, since clogged screw-in nozzles can easily be replaced without having to dismantle the entire air bearing.
