Definitions

  • the invention relates to a deflection wheel for a cartridge feeding device on an automatic multi-tube cannon with a rotating tube bundle and an endless chain for feeding the cartridges to the weapon, with a stationary curve device for radially displacing the cartridges in the deflection wheel and with a number of straight, radially directed guide grooves on the deflection wheel.
  • the cartridges are also supplied by an endless conveyor belt to the multi-tube cannon with a rotating tube bundle.
  • a combing-out wheel which pushes the cartridges out of the conveyor belt and feeds them to the weapon.
  • the cartridges must be accelerated because the division of the conveyor chain is much smaller than the distance between the individual weapon tubes of the tube bundle. In accordance with the small division of the conveyor chain, the cartridges move much more slowly than they should move according to the peripheral speed of the gun barrels (see FIG. 2 of the present application).
  • the combing wheel accelerates the cartridges to the peripheral speed of the tube bundle.
  • the object which is to be achieved with the present invention is to create a deflection wheel which enables the cartridges fed on the conveyor belt to be accelerated uniformly.
  • the deflection wheel When the conveyor belt is deflected by the deflection wheel, the cartridges located on the conveyor belt move on a much larger circular arc than the conveyor belt itself, as a result of which the cartridges are already accelerated.
  • this acceleration alone does not give the cartridge the speed it needs to be inserted into the weapon.
  • the individual cartridges should therefore be additionally accelerated.
  • the endless conveyor belt or an endless conveyor chain could also be designed such that it is deflected on a deflection roller of a relatively small radius, but the cartridges located on the conveyor chain are arranged on a circle of, compared to the radius of the reel, move a very large radius, which could also accelerate the cartridges to the desired speed.
  • a star wheel 10 known per se and provided with five teeth 11 rotates in the direction of arrow A about its axis 12.
  • This star wheel 10 moves an endless conveyor chain 13 in the direction of the two arrows B.
  • a dash-dotted line is indicated in FIG. 1.
  • the shape of the teeth 11 inevitably results from the requirement that the cartridges have to be redirected from a straight line of motion to a circular path of movement and then in turn have to be redirected to a straight line of motion.
  • the transition from the linear to the circular movement path and the transition from the circular to the linear movement path is indicated by the two points 14 and 15.
  • the distance between the individual cartridges 12 increases due to the bending of the conveyor chain 13 by the star wheel 10.
  • the distance between cartridges 12a and 12b is considerably smaller than the distance between cartridges 12b and 12c. This Ab change in position causes acceleration forces that act on the cartridges 12.
  • the cartridges 12 are fed to a firearm, of which only the six gun barrels 16 are indicated. These six weapon tubes 16 are fastened in a housing, not shown, which rotates in the direction of arrow D about an axis 17.
  • the axis of the gun barrel 16a coincides with the axis of the cartridge 12c.
  • the deflection wheel 20 has five sliders 21 which can be moved in the radial direction on the deflection wheel 20, as indicated by arrows E.
  • This deflection wheel 20 moves an endless conveyor chain 22 in the direction of arrow B when the deflection wheel 20 rotates in the direction of arrow A.
  • the cartridges 23 supplied by the conveyor chain 22 enter the troughs 24 of the slide 21.
  • the conveyor chain 22 is also only indicated by a dash-dotted line.
  • the slides 21 are radially displaceably mounted in a disk 25, which can rotate in the direction of arrow A. In front of this disk 25 is a cam disk 26 which cannot be rotated.
  • This cam disk 26 has a control groove or control cam 27 into which rollers 28 protrude, which are mounted on bolts 29 which are fastened to the slides 21.
  • the control groove 27 on the right half of the cam disk 26 has a smaller distance from the axis 30 of the deflection wheel than on the left half of the cam disk 26.
  • the three slides 21 a, b, c are further from the axle 30 removed when the slides 21d and e.
  • the slide 21d thus moves radially outward and at the same time the slide 21a moves radially inward when the deflection wheel 20 rotates a fifth of a turn in the direction of arrow A from the position shown.
  • the control groove 27, which is only indicated schematically here, can be designed such that the cartridge 12b according to FIG. 2 does not move on a circular path 13 but on a spiral path 18 without the unfavorable play indicated in FIG. 2 19 arises.
  • two deflection wheels 20 are arranged on a shaft 31, one deflection wheel 20 of which is located at the rear end of the cartridges to be transported, and the other deflection wheel 20a detects the cartridges in the region of the sleeve mouth.
  • the disks 25 and 25a of the two deflection wheels 20 and 20a are wedged on the shaft 31 and rotate with this shaft 31, on which a gearwheel 32 is wedged at the right end, which can be driven by a motor, not shown.
  • the shaft 31 is mounted in a housing 34 via two ball bearings 33.
  • the cam disc 26a which must not rotate, is fastened to the housing 34 via the sleeve 35, and is thus secured against rotation. Of the five slides 21 shown in FIG.
  • FIG. 4 only one slider 21 and 21 'are visible in FIG. 4.
  • a bolt 29 or 29a is fastened to each slide 21, 21 ', on each of which a roller 28, 28a is mounted, which projects into the control groove 27 or 27a.
  • Guide rails 37, 38 are fastened in the housing 34 and prevent the cartridges 23 from falling out of the slides 21 and 21 '.
  • the cam disk 26 is secured against rotation by a cam 39 which is attached to the housing 34.
  • a sleeve 36 is located between the cam disk 26 and the disk 25.
  • the multi-barrel cannon with a rotating barrel bundle of six weapon tubes 16a, 16b, 16c, 16d, 16e and 16f shoots from each individual weapon barrel e.g. 700 cartridges 12 or 23 per minute.
  • FIG. 2 is considerably smaller than the circular arc b between the weapon tubes 16c and 16d (Fig. 2). According to the difference in length between distance a and arc b, the cartridge must be accelerated to a higher speed. To accelerate the cartridges 12 and 23, they are moved according to FIG. 2 on a spiral path 18, on which they are accelerated approximately to the desired speed. How a cartridge 12, 23 can be moved on a spiral path 18 (FIG. 2) can be seen from FIG. 3.
