Definitions

  • the invention relates to a rapier weaving machine with a device for guiding and storing of a rigidly designed gripper support member.
  • a weaving machine with weft insertion by rapier systems is known, a rack being arranged on or in the rapier rod, which cooperates with a drive pinion, so that the rapier rod and the rapier arranged thereon are inserted into the shed and again can be withdrawn.
  • a rack being arranged on or in the rapier rod, which cooperates with a drive pinion, so that the rapier rod and the rapier arranged thereon are inserted into the shed and again can be withdrawn.
  • a disadvantage of the known roller bearings is that between the rollers and the Gripper bar friction forces are effective, which is a relatively high wear on rollers and Cause gripper bar. Furthermore, the rollers have to be moved with every movement of the gripper bar are also accelerated so that the drive must have a high torque.
  • roller bearings also cause thermal problems because of the Friction between the rollers and the gripper bar generates considerable heat, which is dissipated must become.
  • the object of the invention is therefore, based on the prior art, a device for To guide and store the gripper bar of a weft gripper in weaving machines, which is low-wear, causes little heat development and requires little maintenance required.
  • An essential feature of the invention according to claims 1 and 5 is that the gripper bar of a pneumatic slide bearing is guided and stored. So it's a air-pressure-supported bearing - hereinafter also generally referred to as air bearing - by which the known roller bearing at least in the area of the engagement of the drive pinion in the teeth of the gripper bar is replaced.
  • the air bearing is therefore preferably arranged and acts in the area of the gripper drive pinion from above onto the gripper bar to also a lifting of the gripper bar from Counteract drive pinion.
  • the air bearing according to the invention is also for lateral Guide the gripper rod suitable by the air bearing is designed so that it also Side area of the gripper bar encloses and between the bearing body and the right and left side wall of the gripper bar forms an air cushion.
  • the air bearing consists of a bearing rocker arranged in the longitudinal direction of the gripper rod, 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 rod during the alternating back and forth movement in the horizontal plane.
  • the bearing rocker has an air duct 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 block is fixedly connected to the rocker by connecting means, so that all transverse bores are aligned with one another and compressed air can escape from the rocker via the bores mentioned in the bearing block.
  • the exits of the transverse bores are Bearing ledge expanded to so-called air pockets, which have a larger cross section than that Cross holes in the area of the air inlet. With the help of the air pockets a homogeneous and form a stable air cushion between the plain bearing (bearing block) and the gripper bar.
  • the gripper bar Due to the pneumatic bearing, the gripper bar is almost without friction loss on the Drive pinion guided. Another positive effect is that the air both the bearing itself, as well as the gripper bar cools in the engagement area of the drive pinion.
  • the air bearing can constantly operate with a constant air pressure be charged.
  • pneumatic bearing is controlled by air via the weaving machine control is supplied and therefore only in the camp during the movement phases of the gripper bar Air cushion builds up.
  • pressure valves are activated by the machine control, whereby the air pressure and the air volume individually for each phase of movement of the gripper bar 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 The advantage that cleaning and maintenance of the screw-in nozzles is easier because it is clogged Screw-in nozzles can be quickly exchanged for functional screw-in nozzles. Furthermore, a firm and above all airtight connection between the rocker and Bearing ledge ensures that each screw-in nozzle also acts as a connecting element.
  • the bearing material especially the material of the bearing block, must be together with the Material for the gripper bar 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.
  • Gripper bars today mostly consist of carbon fiber composite materials. On suitable material for the bearing block is therefore e.g. Copper.
  • the rocker is there preferably made of light metal.
  • Figures 1 to 5 show a first embodiment of the air bearing in different views.
  • the gripper bar 12 which in the example has a U-shaped profile integrated rack is formed.
  • the gripper bar 12 carries one at its front end Gripper 14.
  • the gripper bar 12 is driven by a gripper drive pinion 13.
  • a slidable guidance of the gripper bar 12 is provided above the gripper bar 12 pneumatic plain bearing arranged.
  • the pneumatic bearing comprises a rocker 1 which is pivotally mounted about the central axis 3a of the bearing pin 3 by means of a 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 enable vertical adjustment of the gripper bar.
  • 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.
  • a plurality of branches in the direction of the gripper bar 12 Cross bores 6 from the air duct 5.
  • the bearing rocker 1 is connected to a bearing block 8.
  • the bearing strip 8 corresponds in its Width and length approximately the dimensions of the rocker 1 on the output side of the Cross bores 6.
  • cross bores 9 are provided, their number and position corresponds to the cross bores 6 in the rocker 1.
  • the bearing rocker 1 and the bearing block 8 are fixed but releasably connected to one another, e.g. by means of Connecting screws 7, in such a way that the corresponding holes 6, 9 of the Bearing rocker 1 and the bearing block 8 are aligned with each other.
  • Starting from the air duct 5 can the compressed air through the cross bores 6, 9 of the rocker 1 and the bearing block 8 in the direction the gripper bar 12 flow out.
  • the bearing ledge 8 lies against the gripper bar in such a way that forms an air cushion between the bearing bar 8 and the gripper bar 12.
  • the cross holes 9 of the bearing block 8 expanded to air pockets 10 on their side facing the gripper rod 12.
  • the air cushion forms specifically over the entire upper width of the gripper bar 12.
  • the bearing rocker 1 is by means of the bearing pin 3 with the gear housing 15 of the drive pinion 13 connected.
  • the air supply and quantity can advantageously be achieved using the Weaving machine control 16 and the valves 17 of the rocker arm 1 are supplied in a controlled manner.
  • the compressed air flows e.g. from a pressure source 18 via a compressed air line 18a to or several valves 17, the function of which via electrical control lines 19 from the Loom control 16 is affected.
  • 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.
  • 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. 5 shows an enlarged view of FIG. 1 for clarification Cross bores 9 of the bearing block 8, which end in air pockets 10.
  • FIGS. 6 and 7 show a further embodiment of the air bearing, the essential elements and functions described above are realized in an identical manner.
  • a difference to the first embodiment is the construction of the rocker 1 and the bearing block 8.
  • the transverse bores 6 of the bearing rocker 1 are provided with a thread into which a screw-in nozzle 11 provided with at least one air guide channel 26 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.
