Description

Die Erfindung betrifft eine Munitionszuführung für eine Kanone, wobei die Munitionszuführung Einrichtungen für den Transport und die Übergabe von Patronen an die Kanone aufweist.The invention relates to an ammunition feed for a cannon, the ammunition feeder Devices for the transport and transfer of cartridges to the cannon having.

Mit der schweizerischen Patentanmeldung Nr. 01 587/95-6 ist eine Munitionszuführung bekannt geworden, die eine in einem Gehäuse eines Magazins umlaufende Förderkette aufweist. An der Förderkette sind Becher vorgesehen, in welchen Patronen während des Transportes zu einer Trommel einer Revolverkanone gehalten werden. An einer der Trommel zugewandten Umlenkstelle der Förderkette sind auf einer gemeinsamen drehbaren Achse sitzende sternförmige Umlenkräder und sternförmige Übergaberäder angeordnet, wobei die Umlenkräder mit der Förderkette im Eingriff sind. Ein im Bereich der Umlenkräder vorgesehenes erstes Förderglied übernimmt von der Förderkette bzw. den Übergaberädern Patronen, wobei die Patronen entlang einer kreisbogenförmigen Führungsfläche von den Übergaberädern weg auf ein zweites Förderglied transportiert werden. Das erste Förderglied besteht aus zwei auf einer gemeinsamen drehbaren Achse angeordneten dreizackigen Sternen, deren Lücken der Querschnittsform der Patronen angepasst sind. Das zweite Förderglied ist ebenfalls drehbar angeordnet und weist eine Führungsfläche für die Aufnahme jeweils einer Patrone auf. An der Trommel ist ein koaxial zu dieser verlaufender Ladestern befestigt, welchem das zweite Förderglied die Patronen übergibt. Eine oberhalb einer auf dem zweiten Förderglied befindlichen Patrone angeordnete Abtasteinrichtung, beispielsweise in Form einer Lichtschranke, kontrolliert die Position der ersten Patrone. Bei Vorhandensein einer Patrone wird eine Durchladevorrichtung aktiviert und die Patronen in die Trommel eingeschoben. Mit der vorstehend beschriebenen Munitionszuführung können keine schnelleren Schussfolgen erreicht werden. Ausserdem ist der Energieaufwand für die Förderung der Patronen relativ hoch.With the Swiss patent application No. 01 587 / 95-6 an ammunition feeder is known which has a conveyor chain revolving in a housing of a magazine. Cups are provided on the conveyor chain, in which cartridges are held during transport to a drum of a revolver cannon. At a deflection point of the conveyor chain facing the drum, star-shaped deflection wheels and star-shaped transfer wheels are arranged on a common rotatable axis, the deflection wheels being in engagement with the conveyor chain. A first conveyor link provided in the area of the deflection wheels takes cartridges from the conveyor chain or the transfer wheels, the cartridges being transported along a circular guide surface away from the transfer wheels to a second conveyor link. The first conveyor member consists of two three-pointed stars arranged on a common rotatable axis, the gaps of which are adapted to the cross-sectional shape of the cartridges. The second conveyor member is also rotatably arranged and has a guide surface for receiving a cartridge. A loading star running coaxially to the drum is fastened to the drum, to which the second conveying member transfers the cartridges. A scanning device arranged above a cartridge located on the second conveyor element, for example in the form of a light barrier, controls the position of the first cartridge. If a cartridge is present, a through-loading device is activated and the cartridges are pushed into the drum. No faster firing sequences can be achieved with the ammunition feeder described above. In addition, the energy required to convey the cartridges is relatively high.

Der Erfindung liegt die Aufgabe zugrunde eine Munitionszuführung der eingangs genannten Art vorzuschlagen, die vorstehend erwähnte Nachteile nicht aufweist.The invention has for its object a supply of ammunition of the aforementioned Propose a type that does not have the disadvantages mentioned above.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Hierbei ist eine Axial-Transportvorrichtung mit einer Förderkette vorgesehen, mittels welcher die Patronen beim Transport senkrecht zur Bewegungsrichtung der Förderkette in ihrer Längsrichtung verschoben werden. Für den Antrieb der Förderkette ist eine Pufferwelle vorgesehen, wobei der Antrieb durch die Pufferwelle derart erfolgt, dass die Patronen vor der Übergabe an die Kanone in eine Pufferstellung gebracht werden.This object is achieved by the invention specified in claim 1 . In this case, an axial transport device with a conveyor chain is provided, by means of which the cartridges are displaced in their longitudinal direction perpendicular to the direction of movement of the conveyor chain during transport. A buffer shaft is provided for driving the conveyor chain, the drive being effected by the buffer shaft in such a way that the cartridges are brought into a buffer position before being transferred to the cannon.

Die mit der Erfindung erzielten Vorteile sind insbesondere in der Pufferfähigkeit der Axial-Transportvorrichtung zu sehen, wodurch eine schnellere Schussfolge ermöglicht wird und Antriebsenergie gespart werden kann. Die vorgeschlagene Axial-Transportvorrichtung ermöglicht vor allem die Lagerung der Kanone im Schwerpunkt, womit das dynamische Verhalten und der Energiebedarf der Elevationsbewegung der Kanone verbessert werden. Weitere Vorteile sind im modularen Aufbau der erfindungsgemässen Munitionszuführung zu sehen, so dass Herstellungs- und Unterhaltskosten gesenkt werden können.The advantages achieved with the invention are particularly in the buffering capacity of the axial transport device to see what enables a faster firing sequence and Drive energy can be saved. The proposed axial transport device Above all, it allows the cannon to be positioned in the center of gravity, which makes it dynamic Behavior and the energy requirement of the elevation movement of the cannon can be improved. Further advantages are the modular construction of the ammunition feeder according to the invention to see, so that manufacturing and maintenance costs can be reduced.

The casing 32 prevents the cartridges 2 from falling out and has on the inside two axial guides 39 , 40 (FIGS . 2 , 3 ) which run at an oblique angle to the conveying direction of the conveyor chain 34 and by means of which the cartridges 2 during transport are perpendicular to the direction of movement of the conveyor chain 34 be shifted in their longitudinal direction. Starting from the entry of the cartridges 2 at the front transfer wheel 18 of the conveyor deflection station 15 , the axial guides 39 , 40 first cross the lower run and then the upper run of the conveyor chain 34 in order to end at the outlet of the cartridges 2 at the rear transfer wheel 22 of the transfer station 20 . One axial guide 39 guides the cartridges 2 on the sleeve mouth 2.1 when the conveyor chain 34 moves in the direction of the revolver drum 25 , while the other axial guide 40 controls the position of the cartridges 2 and guides them on the sleeve bottom 2.2 when the conveyor chain 34 moves in the direction of the conveyor 6 ( FIG. 3 ). The guide plate 33 is attached to the plates 31.1 , 31.2 . It thus distances the two plates 31.1 , 31.2 and guides or separates the cartridges 2 in the two runs of the conveyor chain 34 from one another.

Die Förderkette 34 besteht nach den Fig. 4, 5, 9 und 10 aus zwei Rollenketten 50, 50' zwischen denen Mitnahmerohre 51 angeordnet sind. An den Enden der Mitnahmerohre 51 sind Endstücke 52 vorgesehen, die Aufnahmebohrungen 53 aufweisen. In die Aufnahmebohrungen 53 greifen Mitnehmerzapfen 54 der Rollenketten 50, 50' mit Spiel ein, wobei das Spiel so bemessen ist, dass eine Schrägstellung der Mitnahmerohre 51 von +/- 2° möglich ist.The conveyor chain 34 is comprised of Figs. 4, 5, 9 and 10 of two roller chains 50, 50 'between which entrainment tubes 51 are arranged. At the ends of the driving tubes 51 , end pieces 52 are provided which have receiving bores 53 . Driver pins 54 of the roller chains 50 , 50 ' engage in the receiving bores 53 with play, the play being dimensioned such that an inclined position of the drive pipes 51 of +/- 2 ° is possible.

Gemäss Fig. 6 und 7 besteht die Pufferwelle aus zwei Teilen, die über eine Klauenkupplung 60 miteinander verbunden sind. An dem einen Kupplungsteil 60.1 sind Bolzen 61 vorgesehen, die in kreisbogenförmige Schlitze 62 des anderen Kupplungsteils 60.2 eingreifen. Die Bogenlänge der Schlitze 62 ist derart bemessen, dass die Kupplungteile 60.1, 60.2 um eine Patronenteilung Pt bzw. dem Abstand der Mitnahmerohre 51 der Förderkette 34 voneinander verdreht werden können. An den Enden der Pufferwelle 35 sind Zahnräder 63, 63' und die Kettenumlenkräder 36, 36' befestigt. 6 and 7 , the buffer shaft consists of two parts which are connected to one another via a claw coupling 60 . On one coupling part 60.1 , bolts 61 are provided which engage in arcuate slots 62 of the other coupling part 60.2 . The arc length of the slots 62 is dimensioned such that the coupling parts 60.1 , 60.2 can be rotated by a cartridge pitch Pt or the distance between the driving tubes 51 of the conveyor chain 34 from one another. At the ends of the buffer shaft 35 gears 63 , 63 ' and the chain deflection wheels 36 , 36' are attached.

Es ist auch möglich die Klauenkupplung anstatt mit festen, durch die Schlitze 62 gegebenen Anschlägen wie in den Fig. 6 und 7 mit federnden Anschlägen auszuführen. Weiterhin ist es möglich die Pufferwelle 35 als Torsionswelle auszubilden, wobei die Verdrehung bis zum maximalen Moment +/- einer halben Patronenteilung Pt/2 entspricht.It is also possible to carry out the claw coupling instead of with fixed stops given by the slots 62 as in FIGS. 6 and 7 with resilient stops. Furthermore, it is possible to design the buffer shaft 35 as a torsion shaft, the rotation corresponding to +/- half a cartridge pitch Pt / 2 up to the maximum torque.

Die Pufferwelle 35 gemäss Fig. 8 weist eine Torsionswelle 65 und ein zu dieser koaxial verlaufendes Anschlagsrohr 66 auf. An den Enden der Torsionswelle 65 sind die Zahnräder 63, 63'und die Kettenumlenkräder 36, 36' befestigt. Das Anschlagsrohr 66 weist an einem Ende zwei Ausschnitte 67 auf, in welche an dem einen Kettenumlenkrad 36 angebrachte Anschläge 68 eingreifen. Das andere Ende des Anschlagrohres 66 ist mit den anderen Kettenumlenkrad 36' fest verbunden. Die Bogenlänge der Ausschnitte 67 ist derart bemessen, dass die Torsionswelle 65 um eine Patronenteilung Pt bzw. dem Abstand der Mitnahmerohre 51 der Förderkette 34 voneinander verdreht werden kann.The buffer shaft 35 according to FIG. 8 has a torsion shaft 65 and a stop tube 66 running coaxially with it. At the ends of the torsion shaft 65, the gears 63, 63 'and the chain reversing wheels 36, 36' attached. The stop tube 66 has at one end two cutouts 67 , into which stops 68 attached to the one chain deflection wheel 36 engage. The other end of the stop tube 66 is fixedly connected to the other chain deflection wheel 36 ' . The arc length of the cutouts 67 is dimensioned such that the torsion shaft 65 can be rotated from one another by a cartridge pitch Pt or the distance between the driving tubes 51 of the conveyor chain 34 .

In der Fig. 11 ist der Absisse die Zeit t und der Ordinate der Drehwinkel W der Revolvertrommel 25 zugeordnet. Mit K1 ist eine Weg/Zeitkennlinie der einen Rollenkette 50, und mit K2 eine Weg/Zeitkennlinie der anderen Rollenkette 50' der Förderkette 34 bezeichnet. Die Koordinaten R1 bis R5 bezeichnen Zeitpunkte von Schüssen, die bei einer Umdrehung der Revolvertrommel 25 während eines bestimmten Zeitabschnittes abgefeuert werden. Eine auftretende Wegdifferenz D der beiden Rollenketten 50, 50' wird durch die mit der Pufferwelle 35 erzielten Pufferwirkung der Axial-Transportvorrichtung 19 und gegebenenfalls durch das Spiel der Förderkette 9 des Förderes 6 ausgeglichen. Mit St-F und St-K sind Stopps des Förderers 6 und der Revolverkanone bezeichnet. 11 , the abscissa is assigned the time t and the ordinate the rotation angle W of the turret drum 25 . K1 denotes a path / time characteristic of one roller chain 50 , and K2 denotes a path / time characteristic of the other roller chain 50 'of the conveyor chain 34 . The coordinates R 1 to R 5 denote times of shots that are fired during one revolution of the revolver drum 25 during a certain period of time. An occurring path difference D of the two roller chains 50 , 50 ' is compensated for by the buffer effect of the axial transport device 19 achieved with the buffer shaft 35 and, if appropriate, by the play of the conveyor chain 9 of the conveyor 6 . St-F and St-K denote stops of the conveyor 6 and the turret gun.

Die vorstehend beschriebene Axial-Transportvorrichtung 19 arbeitet wie folgt: Vor dem Schiessen wird die eine Rollenkette 50 der Axial-Transportvorrichtung 19 vom Getriebe der Förderer-Umlenkstation 15 über das mit dem vorderen Übergaberad 18 verbundene Zahnrad und das Zahnrad 63 der Pufferwelle 35 sowie über das Kettenumlenkrad 36 angetrieben, wobei der eine Teil der Pufferwelle 35 bis zum Anschlag um eine halbe Patronenteilung Pt/2 verdreht wird (Fig. 9).The axial transport device 19 described above works as follows: Before firing, the roller chain 50 of the axial transport device 19 is moved from the transmission of the conveyor deflection station 15 via the gearwheel connected to the front transfer wheel 18 and the gearwheel 63 of the buffer shaft 35 as well as via the Chain deflection wheel 36 driven, one part of the buffer shaft 35 being turned as far as possible by half a cartridge pitch Pt / 2 ( FIG. 9 ).

Bei diesem Vorgang blockiert das Getriebe der Übergabestation 20 über das Zahnrad 63' und den anderen Teil der Pufferwelle 35 mit dem Kettenumlenkrad 36' die andere Rollenkette 50', so dass sich die Mitnahmerohre 51 der Förderkette 34 und die Patronen 2 um einen Winkel von ungefähr 2° aus der Mittellage schräg stellen und eine Pufferstellung einnehmen (Fig. 9). Beim Schiessen kann nun die Kanone eine Patrone 2 abziehen, ohne dass sich die eine Rollenkette 50 bewegen muss. Durch den beim Schiessen entstehenden Explosionsdruck dreht sich die Revolvertrommel 25, so dass die andere Rollenkette 50' über die Übergabestation 20 und das Zahnrad 63' sowie das Kettenumlenkrad 36' sehr schnell angetrieben wird, und die Mitnahmerohre 51 sowie die Patronen 2 um einen Winkel von ungefähr 2° in die andere Richtung schräg gestellt werden (Fig. 10).In this process, the transmission of the transfer station 20 via the gear 63 ' and the other part of the buffer shaft 35 with the chain deflection wheel 36' blocks the other roller chain 50 ' , so that the driving tubes 51 of the conveyor chain 34 and the cartridges 2 are at an angle of approximately 2 ° from the middle position and take a buffer position ( Fig. 9 ). When firing, the cannon can now pull off a cartridge 2 without the roller chain 50 having to move. The revolving drum 25 rotates due to the explosion pressure that arises during the shooting, so that the other roller chain 50 'is very quickly driven via the transfer station 20 and the gear 63' and the chain deflection wheel 36 ' , and the driving tubes 51 and the cartridges 2 by an angle of be inclined approximately 2 ° in the other direction ( FIG. 10 ).

Während des Schiessens bewegen sich die Rollenketten 50, 50' der Förderkette 34 gleichzeitig gemäss den Weg/Zeitkennlinien K1 bzw. K2 in Fig. 11. Die Revolvertrommel 25 der Kanone treibt die eine Rollenkette 50' schrittweise an, welche sich dabei sehr schnell bewegt und wieder gestoppt wird, und zwar zweimal pro Schuss (R1 bis R5, K2, Fig. 11). Die andere, von der Förderer-Umlenkstation 15 angetriebene Rollenkette 50 läuft kontinuierlich und folgt der mittleren Kadenz der Kanone K1, Fig. 11). Hierbei wird unter Ausnützung der aufgrund der Pufferwelle 35 gegebenen Pufferfähigkeit der Axial-Transportvorrichtung 19 und gegebenenfalls des Spieles der Förderkette 9 des Förderers 6 Antriebsenergie gespart.During the firing, the roller chains 50 , 50 'of the conveyor chain 34 move simultaneously according to the path / time characteristics K1 and K2 in FIG. 11 . The revolver drum 25 of the cannon drives the one roller chain 50 ' step by step, which moves very quickly and is stopped again, twice per shot ( R1 to R5 , K2 , FIG. 11 ). The other roller chain 50 , driven by the conveyor deflection station 15 , runs continuously and follows the middle cadence of the cannon K1 ( FIG. 11 ). This saves drive energy by utilizing the buffer capacity of the axial transport device 19 given by the buffer shaft 35 and possibly the play of the conveyor chain 9 of the conveyor 6 .

Bei Verwendung einer Torsionswelle als Pufferwelle, wird die Torsionswelle vor dem Schiessen vom Förderer 6 aus einer Mittellage um eine halbe Patronenteilung Pt/2 vorgespannt. Beim Schiessen entspannt die Kanone beim Abziehen einer Patrone 2 diese Vorspannung und spannt dann ihrerseits die Torsionswelle in entgegengesetzter Richtung vor.When using a torsion shaft as a buffer shaft, the torsion shaft is preloaded by the conveyor 6 from a central position by half a cartridge pitch Pt / 2 before firing. When firing, the cannon relaxes this preload when a cartridge 2 is pulled out and then in turn prestresses the torsion shaft in the opposite direction.
