Definitions

  • the invention relates to a charging device with the features of the preamble of patent claim 1.
  • Such a charging device is known from CH-PS-431 330.
  • This arrangement is very susceptible to failure because of the need for a spring and a large number of individual parts. It is also not suitable for caseless ammunition and it requires a reciprocating drive for the movement of the carrier of the carrier.
  • a loading direction with an endless chain rotating in only one direction with at least one towing element is known from US Pat. No. 2,410,116.
  • the loading chain is arranged in the rear extension of the weapon barrel in such a way that it wraps around two sprockets that can be rotated axially about horizontal axes.
  • a chain drum on the upper side moving against the tube ensures, by means of the towing element, that the respective ammunition unit is transported in a straight line and aligned with the tube core axis.
  • the towing element is guided through the area of the locking wedge around a sprocket wheel from the upper drum to the lower drum of the loading chain. High cadences are therefore not possible with the charger according to the US PS.
  • the invention is therefore based on the object of providing a loading device of the type mentioned at the outset which permits high cadences and at the same time precludes obstruction of the locking wedge and prevents the ammunition unit from rebounding with certainty. It should be possible to use a drive rotating in one direction and a robust construction which is not susceptible to faults and with few individual parts should be created. It should also be used for ammunition without a cartridge case.
  • an automatic tube weapon has a tube 77 with a core axis A1, the rear part of which is held in a weapon housing 81.
  • a closure part 79 is arranged to be drivable in a manner not shown.
  • an axis A3 which is a front 59 and a rear bearing 61, extends in a feeder housing 90.
  • an axis of rotation A4 of a control roller 51 mounted at 59 and 61 is essentially in the form of a circular cylindrical cross section.
  • a control groove 53 with a front 78 and a rear deflection area 80 (see also FIG. 4) and a central crossing area 57 extends over the outer lateral surface of the control roller 51.
  • the control roller 51 can be driven at 55 in a manner not shown in detail.
  • the feeder housing 90 has a left-hand and a right-hand gerard guide groove 92 (not shown) for a carrier 26.
  • the carrier 26 (see also FIGS. 5 and 6) has a lower opening 42 and a top opening 43 in a housing (not designated in more detail), which are designed as bearings for a control member 45.
  • the openings 42 and 43 are aligned with one another and enclose a pin-shaped force-locking member 63 on the underside and a pivot pin 63 coaxial therewith.
  • the control member 45 is provided on a front surface 47, the track of which follows an arc in the plane of the drawing, with a control groove 49 (see also FIG. 2).
  • the latter serves to control a driver 10 for upward and downward movement.
  • the driver 10 has at the free end of a front cantilever, not specified a nose 12 and is mounted in the carrier 26 by means of an ankle weld 14 about an axis 16 crossing the axis A1 of the soul.
  • a rear end of the driver 10 facing away from the nose 12 is designed as a ball 18, which corresponds to the control groove 49 in a force-fitting manner.
  • the free end of the force-locking member 63 facing the control roller 51 is rigidly connected to a guide element 67, the two parts of which, not specified in more detail, include a guide roller 67 'between them.
  • the length 73 of the guide element 67 is greater than the width 75 of the control groove 53.
  • the rotation of the control roller 51 results in a movement of the connection between the control member 45 and the control groove 53 via the force-locking member 63 with the elements 67 and 67 ' by straight guide grooves 92 linearly guided carrier 26 in the direction of arrows R1 and R2.
  • the control member 45 rotates with an upward and downward movement of the nose 12 of the driver 10, which is to be described in more detail, via the frictional connection between the ball 18 with the control groove 49.
  • the feeder housing 90 with the straight guide 92 for the carrier 26 encloses an arrangement with a roller chain 62 which is guided around a front 66 and a rear sprocket 70 and which integrates a stud bolt 64 directed upwards against the carrier 26.
  • the two sprockets 66 and 70 are arranged to rotate counterclockwise about a respective axis 68 or 72, the extensions of which intersect a rear extension of the tube core axis A1, not shown here, at 90 °.
  • the control element 46 which is of bar-shaped design here, is schematically indicated in four different positions in FIG.
  • the carrier 26 encloses with its upper part 28 with guide surfaces 30, 32, 34 and 36 a receptacle for the control member 46.
  • the latter has a control groove 50 in the region of its front surface 48, which is shown in FIG.
  • the driver 10 with its front nose 12 and its rear ball 18 is in turn mounted for the upward and downward movement in the direction of the arrows R3 and R4 about the articulation axis 16 crossing the tube core axis A1 by means of the articulation shaft 14.
  • the ball 18 passes through a front-side opening 44 in the upper part 28 and corresponds non-positively to the control groove 50 in the control member 46.
  • An underside opening 42 in the upper part 28 of the carrier 26 is an underside receptacle 60 in the control member 46 for the free end of the stud bolt facing away from the roller chain 62 64 assigned.
  • the stud 64 moves in the direction of the arrow R5, wherein it moves the control member 46 in the support 26 from a position 52 to a position 54, from which it moves via a position 56 in the front deflection area 78 as the stud continues to rotate 64 to position 58 and finally back to position 52.
  • the control member 46 is moved transversely with respect to the direction of movement in the direction of the arrows R1 and R2 of the carrier 26, the driver 10 is deflected with its nose 12 in the direction of the arrows R3 and R4.
  • the carrier 26 is in the position shown in FIG. 1 in section and in FIG. 4 in plan view and there with "52" (the reference sign in quotation marks refers to the inevitable mutual spatial position in the relevant position of the carrier 26 Assignment of the control groove 49; 50 to the cone 18).
  • an ammunition unit 85 with a projectile 87 and a caseless propellant body 89 is brought “over center” in such a way that its axis A2 is aligned with the core axis A1 of the tube 77.
  • the driver 10 is deflected by its nose 12 via the control member 45, 46 in such a way that the latter is in contact with a base surface 89 'of the propellant charge body 89 of the ammunition unit 85; the ball 18 is located in that area of the control groove 49; 50, which is designated 52 in FIGS. 2 and 7.
  • the locking wedge 79 is in the position shown in Figure 1.
  • the ammunition unit 85 is inserted in a straight line and in the aforementioned sense, axially aligned in the cargo space 83 in such a way that the nose 12 as long as Contact with the base surface 89 'of the ammunition unit 85 remains until the locking wedge 79 from its open position shown in FIG. 1, on its downward movement in the direction of the arrow R7, covers an unspecified upper region of the base surface 89' on the back, so that advantageously also at high speed a bouncing back of the ammunition unit 85 in the cargo space 83 is prevented.
  • the rear deflection area 80 is the relative movement of the control groove 49; 50 assigned to the ball 18 by the already mentioned position 52; the driver 10 is deflected with his nose 12 again in the direction of arrow R4 at the end of the firing cycle described, so that contact between the nose 12 and the base surface 89 'of a next ammunition unit 85 is possible again.
  • FIGS. 1-10 In the exemplary embodiment according to FIGS.
  • control member 45 moves as a rotation about the axis A5 as a result of the deflecting guidance of the guide element 67 in the control groove 53.
  • Figure 3 the control member 46 is superimposed on the linear movement of the carrier 26 in the direction of the arrows R1 or R2 in the direction of the arrows R5 or R6 transversely to the respective direction of movement of the carrier 26.
  • the loading device according to the invention is described, illustrated and claimed in connection with an automatic barrel weapon with a cross closure.
  • the best-known and most important example of a cross lock is the wedge lock, which has a locking wedge that can be moved back and forth transversely to the tube core axis.
