Definitions
- the invention relates to the supply of different types of ammunition from different ammunition containers via a common rotor to a weapon, wherein at least two different types of ammunition of the weapon are presented from the same direction a closure or the like.
- DE 689 05 739 T2 (EP 0 362 064 B1) discloses an automatic rapid-fire turret, in which the ammunition supply system has a star shaft which is located in the extension of the axis of the turret and is rotatably connected thereto. Included is a solid wiper, which is placed between the star wave and a feed star to separate the cartridges from the belt members of the belt. The feed star is driven in rotation by the star wave.
- the supply of ammunition in the known as Bushmaster automatic weapon takes place laterally from one direction.
- the ammunition is supplied from two ammunition canals, whereby the ammunition is passed through so-called degestering stems into the common roof via a switch. is pressed, which has been selected.
- the two stars rotate in opposite directions, so that here too the ammunition is inserted alternately.
- the invention has as its object to bring different types of ammunition or types of different ammunition containers on a common rotor, which are then fed to a weapon or a cartridge chamber.
- the invention is based on the idea to present two or at least three or four types of ammunition located in different ammunition containers, channels or the like via a common drive to a rotor, wherein a powerless insertion into the rotor is favored.
- the insertion of the ammunition from the various ammunition containers and / or channels in the rotor takes place, for example, clockwise and / or counter.
- the problem to be solved was that the various ammunition from different positions to the rotor must be inserted into this.
- This problem has been solved in that the insertion stars are designed as half stars, which are synchronized with the rotor and that each ammunition within the rotor comes to rest at different rotor positions.
- This has the advantage, among other things, that only one ammunition can always be in the rotor and that switching to another ammunition channel ensures that no false ammunition comes to rest in the rotor and is fired.
- the rotor then, for example, returns a shorter path for feeding the ammunition to the shot from the first channel than for feeding the ammunition to the shoot from the second channel.
- the unneeded inserter is mechanically separated from the drive.
- the synchronization between the rotor and the starter itself is primarily mechanically, an electronic monitoring can be provided.
- Used is a rotor shaft with a preferably three-gear jaw clutch, driven by a rotor motor.
- the dog clutch is in turn by a control roller or Operating shaft. All three gears for feeding the at least three types of ammunition are preferably continuously engaged with the rotor shaft, in the power engagement, however, is only the gear, which is responsible for the supply of the selected ammunition. This force intervention is realized by the respective dog clutch on the rotor shaft.
- the rotor shaft is further connected via a linkage with a 2-way clutch and a shaft, here called Entgurterwelle, which in turn is driven by a booster.
- Entgurterwelle a shaft
- a control roller also ensures that only one gear is in force engagement with the Entgurterwelle.
- FIG. 1 is an illustration of a feeder in a plan view
- FIG. 5 is an enlarged view of FIG. 5,
- Fig. 7 is an illustration of the control roller of the rotor shaft.
- a feeder for example, three different types of ammunition M1, M2, M3 (the latter not visible here) characterized.
- the feeder 1 has six stars - -
- the star S1 is the rotor 2, through which the ammunition M1, M2, M3 is placed in front of a closure 3.
- the ammunition M1 and M2 have belt members 4.
- a common drive 5 takes over the supply of the ammunition M1, M2, M3 in front of the shutter. 3
- Fig. 2 and Fig. 3 show the drive 5 for the three types of ammunition M1, M2, M3 in a compact representation.
- the feeder 1 is subdivided into a rotor side 7 and into a so-called degressor side 8.
- the Entgurterseite 8 is gear technology independent of the rotor side 7 and a rack 9, which actuates the clutches 10, 11, connected together (allows a modular design of the feeder 1).
- the drive 5 of the feeder 1 comprises in the preferred embodiment, a rotor shaft
- FIG. 4 shows an enlarged view of the drive 5 with the rotor shaft 12 and the 3-speed dog clutch 10, a transmission 14 (clutch) and the rack or linkage 9.
- the 3-speed dog clutch 10 is in turn with gears Z1, Z2, Z3 of the transmission 14 in engagement, wherein a frictional connection is made with the gear, which represents the selected Munitionsart M1, M2, M3.
- the mechanical force engagement of the jaws 15 (Fig. 5) of the dog clutch 10 is provided by a switching shaft 16, which is designed here as a control roller (Fig. 7).
- the other gears are blocked by means 17 ( Figure 6) on the jaws 15.
- the rack 9 is connected to the 2-way clutch 11, which also includes a dog clutch, here a 2-speed clutch.
- This double-clutch 11 is also operated by a control roller 18 (not shown), so that the clutch 11 is positively connected to the gear Z4, Z5 of the transmission 19, which the degester star S4, S5 and insertion star S2, S3 functionally integrated into the system and thus the corresponding ammunition M1, M2, which has been selected, is supplied from the corresponding ammunition channel to the system.
- the three clutch 10 determines the supply stroke for M1, M2 or M3, the two clutch 11, the insertion of M1 or M2 in a respective insertion star S2, S3 and via this in the common rotor. 2
- FIG. 7 illustrates one of the two control rollers 6.
- the control cams St 1, St 2, St 3 determine the engagement of the claws in the rotor shaft 12 and thus the engagement in the corresponding gear Z1, Z2, Z3 for connection to the rotor shaft 12th
- Shown in the view of Fig. 5 is the engagement of the jaws in the central gear (selection of ammunition M1) in the rotor shaft 12.
- the gear Z2 is driven by the rotor shaft 12, which is equivalent to the fact that the ammunition M1 from the first Ammunition channel to be supplied to the rotor 2.
- the gear Z4 with the Entgurterstern S4 is engaged and the inlay S2 is operated.
- the process of feeding is as follows:
- the supply of ammunition M1 is selected.
- the middle jaw 15 engages with the rotor shaft 12 and thus the gear Z2.
- the derailment star S4 is driven by the booster via the linkage 9 and the toothed wheel Z4, and the insertion star S2 is addressed, so that the ammunition M1 is enttudenet and placed over the insertion star S2 in the rotor 2 (S1).
- the gears Z1, Z3 of the transmission 14 are disengaged, as well as the gear Z5 of the transmission 19th
- the rotor 2 can take a defined position according to the selection of ammunition: 0, 60, 120, 180, 240 or 360 degrees.
- the booster must in turn take a position 0, 180 or 360 degrees.
- the booster With regard to the third type of ammunition M3, the booster remains de-energized.
- the function of the feeder 1 and the interaction with the weapon can be monitored by sensors.
- the motors have at least one encoder and / or resolver.
- Amend the ammunition selection must have taken a defined position 0, 60, 120, 180, 240 or 360 degrees.
- the booster encoder in turn has to take a position 0, 180 or 360 degrees.
- the selected ammunition M1, M2, M3 is conveyed to the feed position by rotation of the rotor 2.
- the rotation is terminated by reaching the feed position, in which a match of encoder value and monitoring rotor signal is confirmed.
- the rotor 2 is held in this position and the booster motor and another weapon motor (not shown in detail) are started
- the booster motor turns the star S4 for the ammunition M1 or S5 for the ammunition M2 by 90 depending on the signal "Ammunition x is selected" Degree in time corresponding to the given cadence. If ammo M3 is selected, the booster motor will not turn.
- the weapon engine is started and runs with given values.
- the "lock locked” signal releases a firing pin in the shutter and normally ignites the supplied cartridge.
- the ignition is detected via the weapon return and the signal “shot” is generated. With this signal, the weapon motor continues to run until the signal "lock behind” is present (not shown).
- the shutter 3 remains locked and is unlocked only after a time y which can be set, for example, by driving a magnet, then turning it on Continued running of the weapons engine allows, so that the failure can then be transported out of the weapon system like a normal sleeve.
- the signal for switching ammunition can be generated at any time. If the ammunition is in the relevant star S2 or S3 or S6, the firing state will be checked for the duration of the changeover , At the same time a signal "Switch to ammunition x" is generated and the response is waited for If there is no ammunition, an error signal is generated and the system can then be set to "ready to shoot".
- the described feeder 1 is designed so that a fourth ammunition can be supplied to the rotor 2.
