Description

Die Erfindung betrifft eine Überwachungseinrichtung von Spätzündern für ein fremdangetriebenes Geschütz, mit einem Munitionszuführgehäuse, in dem eine Weiche verschiebbar gelagert ist, welche bei einer Zündverzögerung die der Waffe zugeführten Patronen in einen Ausstosskanal umleitet und diese auf einer Endloskette bleiben.The invention relates to a monitoring device for late detonators for an externally powered gun, with an ammunition feed housing, in which a switch is slidably mounted, which, in the event of a delay in ignition, redirects the cartridges supplied to the weapon into an ejection channel and these remain on an endless chain.

Bei einer bekannten Sicherheitsvorrichtung dieser Art (siehe EP-A-0111 240), werden die Patronen durch ein Sternrad in das Waffengehäuse transportiert und dort durch einen oder mehrere Verschlüsse in ein bzw. mehrere Waffenrohre geschoben. Nach dem Abfeuern der Patronen werden die leeren Hülsen aus dem Waffenrohr herausgezogen und ausgeworfen. Bei einer Zündverzögerung wird die Patrone nicht mehr aus dem Waffenrohr herausgezogen und es darf keine weitere Patrone mehr zugeführt werden. Die durch das Sternrad zugeführten Patronen werden daher nicht mehr der Waffe zugeführt, sondern auf einer Endloskette zurückgeführt. Zu diesem Zwecke wird bei einer Zündverzögerung eine Weiche umgeschaltet, damit die Patronen nicht mehr zur Waffe transportiert werden, sondern auf der Endloskette bleiben.In a known security device of this type (see EP-A-0111 240), the cartridges are transported into the weapon housing by means of a star wheel and are pushed there into one or more gun barrels by one or more locks. After the cartridges have been fired, the empty cases are pulled out of the barrel and ejected. If the ignition is delayed, the cartridge is no longer pulled out of the barrel and no more cartridges may be added. The cartridges fed through the star wheel are therefore no longer fed to the weapon, but instead are returned on an endless chain. For this purpose, a switch is switched in the event of an ignition delay, so that the cartridges are no longer transported to the weapon, but remain on the endless chain.

Diese bekannte Weiche hat verschiedene Nachteile:

  • a) In der kurzen zur Verfügung stehenden Zeit muss die Weiche um einen verhältnismässig grossen Winkel geschwenkt werden.
  • b) Eine solche Weiche besitzt eine verhältnismässig grosse Masse, die in der kurzen zur Verfügung stehenden Zeit verschwenkt werden muss. Sowohl die Verschwenkung um einen grossen Winkel, als auch die Verschwenkung einer grossen Masse in einer kurzen zur Verfügung stehenden Zeit, erfordert grosse Beschleunigungs- und Verzögerungskräfte und führt zu einem grossen Verschleiss.
  • c) Diese Weichen erlauben kein direkt nachfolgendes Verschiessen der umgelenkten Patronen, diese werden in einen separaten Behälter ausgeworfen.
This known switch has several disadvantages:
  • a) In the short time available, the switch must be pivoted through a relatively large angle.
  • b) Such a switch has a relatively large mass, which must be pivoted in the short time available. Both the swiveling by a large angle and the swiveling of a large mass in a short time available require great acceleration and deceleration forces and lead to great wear.
  • c) These switches do not allow the deflected cartridges to be fired immediately afterwards; they are ejected into a separate container.

Die Aufgabe, die mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung einer Überwachungsvorrichtung, mit einer Weiche, die einen verhältnismässig kleinen Hub ausführt und eine verhältnismässig kleine Masse aufweist und somit kleine Schaltkräfte benötigt, damit der Varschleiss klein ist und ein zuverlässiges Umschalten gewährleistet ist.The object that is to be achieved with the present invention is to provide a monitoring device with a switch which carries out a relatively small stroke and has a relatively small mass and thus requires small switching forces so that the var wear is small and reliable switching is guaranteed.

Die Überwachungseinrichtung, mit der diese Aufgabe gelöst wird, ist dadurch gekennzeichnet, dass die Weiche aus zwei in Richtung der Patronanachsen verschiebbaren Segmentan besteht, von denen wahlweise eines in die Bahn der Patronen hineinragt. Vorzugsweise sind die beiden Segmente an den Enden eines Waagebalkens angelenkt, der in einem Gehäuse schwenkbar gelagert ist um zwangsläufig die beiden Segmente in entgegengesetzter Richtung zu verschieben. Bei einer bevorzugten Ausführungsform ist mindestens eine Druckfeder vorhanden, die sich einerseits am einen Segment und andererseits am Gehäuse abstützt und das Bestreben hat, das eine Segment in Wirkstellung und das andere Segment in seine unwirksame Stellung zu verschieben. Vorzugsweise ist zur Betätigung der Segmente an einem Segment ein Betätigungskabel befestigt, um dieses Segment entgegen der Kraft der Druckfeder in seine unwirksame Stellung zu schieben. Gemäss einer bevorzugten Ausführungsform sind zur Führung der Segmente im Gehäuse Führungszapfen befestigt, welche in Bohrungen der Segmente hineinragen, wobei die Segmente auf diesen Zapfen verschiebbar sind.The monitoring device with which this object is achieved is characterized in that the switch consists of two segments which can be displaced in the direction of the cartridge axes, one of which optionally projects into the path of the cartridges. The two segments are preferably articulated at the ends of a balance beam which is pivotally mounted in a housing in order to inevitably move the two segments in the opposite direction. In a preferred embodiment, there is at least one compression spring, which is supported on the one hand on a segment and on the other hand on the housing and has the endeavor to shift one segment into the active position and the other segment into its inactive position. An actuating cable is preferably attached to a segment in order to actuate the segments in order to push this segment into its inactive position against the force of the compression spring. According to a preferred embodiment, guide pins which protrude into bores of the segments are fastened in the housing for guiding the segments, the segments being displaceable on these pins.

  • Fig. 3 einen Schnitt nach Linie 111-111 in Fig. 2 und
  • Fig. 4 einen Schnitt nach Linie IV-IV in Fig. 2 ,
  • Fig. 5 einen Schnitt nach Linie V-V in Fig. 1.
An exemplary embodiment of a monitoring device for late bloomers on a firearm, in particular a Gatling cannon, is described in detail below with reference to the accompanying drawing. - It shows:
  • 1 shows a cross section through a cannon and the ammunition supply with the monitoring device according to the invention;
  • 2 shows a view on an enlarged scale through the monitoring device alone;
  • Fig. 3 is a section along line 111-111 in Fig. 2 and
  • 4 shows a section along line IV-IV in FIG. 2,
  • 5 shows a section along line VV in FIG. 1st

Gemäss Fig. 1 sind von einer Gatling-Kanone 10 nur die sechs Waffenrohre 11 sichtbar. Diese sechs Waffenrohre 11 sind in einem nicht dargestellten Rotor befestigt, der in an sich bekannter Weise um die Waffenachse 12 drehbar gelagart ist. An der Stella A werden den Verschlüssen der Waffenrohre 11 Patronen 13 zugeführt, wie weiter unten beschrieben. An der Stelle B werden die Patronen in an sich bekannter Weise abgefeuert. An der Stelle C wird durch ein Tastorgan festgestellt, ob die Patrone abgefeuert wurde. An der Stelle D werden die leeren Patronenhülsen 14 ausgestossen, wie ebenfalls weiter unten beschrieben.1, only the six gun barrels 11 are visible from a Gatling cannon 10. These six weapon tubes 11 are fastened in a rotor, not shown, which is rotatable about the weapon axis 12 in a manner known per se. At the Stella A 11 cartridges 13 are fed to the breeches of the weapon barrels, as described further below. At point B, the cartridges are fired in a manner known per se. At point C, a feeler determines whether the cartridge has been fired. At point D, the empty cartridge cases 14 are ejected, as also described below.

Die Vorrichtung zum Zuführen der Munition zur Feuerwaffe 10 weist ein Gehäuse 15 auf, in welchem drei Sternräder 16, 17 und 18 drehbar gelagert sind. Der Antrieb dieser drei Sternräder 16,17,18 erfolgt über ein nicht dargestelltes Zahnradgetriebe. Das erste, auch als Zuführrad bezeichnete Sternrad 16 besitzt fünf Aufnahmestellen für die Patronen. Das zweite, auch als Übergaberad bezeichnete Sternrad 17 besitzt nur vier Aufnanmestellen für die der Waffe 10 zuzuführenden Patronen 13. Das dritte, auch als Auswerfrad bezeichnete Sternrad 18 weist vier Aufnahmestellen für die leeren Patronenhülsen 14 auf..The device for feeding the ammunition to the firearm 10 has a housing 15 in which three star wheels 16, 17 and 18 are rotatably mounted. These three star wheels 16, 17, 18 are driven by a gear transmission (not shown). The first star wheel 16, also called the feed wheel, has five receiving points for the cartridges. The second star wheel 17, also referred to as a transfer wheel, has only four pick-up points for the cartridges 13 to be fed to the weapon 10. The third star wheel 18, also referred to as an ejection wheel, has four pick-up points for the empty cartridge cases 14.

Das erwähnte Gehäuse 15 besitzt drei Öffnungen, nämlich eine Eintrittsöffnung 19, durch welche die zu verschiessende Munition, d.h. die Patronen 13 zugeführt werden, eine erste Austrittsöffnung 20, durch welche allfällig nicht verschossene, aber noch scharfe Patronen auf einem nicht dargestellten Endlosband verbleiben und eine zweite Austrittsöffnung 21, durch welche die leeren Patronenhülsen 14 ausgestossen werden. Die Zufuhr der Patronen 13 bis in die Eintrittsöffnung 19 erfolgt in an sich bekannter Weise, durch ein nicht dargestelltes, endloses Förderband oder ein anderes an sich bekanntes Transportorgan. Die in der Eintrittsöffnung 19 befindlichen Patronen 13 werden von den Aufnahmestellen oder - Schalen 22 des Zuführrades 16 erfasst und bis zur Stelle E transportiert. An dieser Stelle E befindet sich die Patrone 13 nicht nur in der Aufnahmeschale 22 des Zuführerrades 16, sondern bereits auch in einer Aufnahmeschale 23 des Übergaberades 17. Von der Stelle E kann die Patrone 13 entweder durch das Übergaberad 17 an die Stelle A der Kanone 10 zugeführt werden, oder durch das Zuführrad 16 an die Austrittsöffnung 20 zurückbewegt werden, wie durch die beiden Pfeile 24 und 25 angedeutet ist. Um die Patrone 13 entweder in die Richtung des Pfeiles 24 der Waffe 10 zuführen zu können oder in Richtung des Pfeiles 25 wieder in den Munitionsbehälter zurückführen zu können, sind zwei bewegliche Segmente 26 und 27 vorhanden. Diese beiden Segmente 26 und 27 lassen sich aus einer Wirkstellung in eine unwirksame Stellung verschieben. Falls sich das eine Segment 27 in seiner Wirkstellung befindet, gelangen die Patronen 13 zur Waffe 10 und falls sich das andere Segment 26 in seiner Wirkstellung befindet, verbleiben die Patronen auf dem Endlosband und können anschliessend ins Magazin zurückgeführt werden.The housing 15 mentioned has three openings, namely an inlet opening 19 through which the ammunition to be fired, ie the cartridges 13 are fed, and a first outlet opening 20 through which there may not be closed, but still sharp cartridges remain on an endless belt, not shown, and a second outlet opening 21 through which the empty cartridge cases 14 are ejected. The cartridges 13 are fed into the inlet opening 19 in a manner known per se, by means of an endless conveyor belt (not shown) or another transport means known per se. The cartridges 13 located in the inlet opening 19 are gripped by the receiving points or shells 22 of the feed wheel 16 and transported to the point E. At this point E, the cartridge 13 is not only in the receiving shell 22 of the feeder wheel 16, but also already in a receiving shell 23 of the transfer wheel 17. From the point E, the cartridge 13 can either through the transfer wheel 17 to the point A of the cannon 10 be supplied, or be moved back through the feed wheel 16 to the outlet opening 20, as indicated by the two arrows 24 and 25. In order to be able to either feed the cartridge 13 in the direction of the arrow 24 of the weapon 10 or to be able to return it to the ammunition container in the direction of the arrow 25, two movable segments 26 and 27 are provided. These two segments 26 and 27 can be moved from an active position to an inactive position. If one segment 27 is in its active position, the cartridges 13 reach the weapon 10 and if the other segment 26 is in its active position, the cartridges remain on the endless belt and can then be returned to the magazine.

Gemäss Fig. 2-4 sind die beiden Segmente 26 und 27 in einem Gehäuse 28 verschiebbar angeordnet. Zur genauen Führung der Segmente 26 und 27 im Gehäuse 28 sind im Gehäuseboden 29 vier Zapfen 30 befestigt, welche in entsprechende Bohrungen der Segmente 26 und 27 hineinragen. An jedem Ende der beiden Segmente 26 und 27 ist je ein Zapfen 31 befestigt welcher in eine entsprechende Bohrung von zwei Waagebalken 32 hineinragt. Die beiden Waagebalken 32 sind um Bolzen 33 schwenkbar im Gehäuse 28 gelagert und haben die Aufgabe, beim anheben des einen Segmentes das andere Segment zu senken. Zwei Tellerfederpakete 34 haben das Bestreben das Segment 26 aus seiner gezeigte, untersten Stellung (Fig. 3) in seine oberste Stellung zu drücken. Ein Kabel 35, das mit Hilfe einer Schraube 36 am Segment 26 befestigt ist, kann das Segment 26 entgegen der Kraft der Tellerfederpakete 34 in die gezeigte, unterste Stellung ziehen. In der Ausgangsstellung gemäss Fig. 3 und 4 ist das Kabel 35 gespannt und die Tellerfederpakete 34 sind komprimiert. Das Segment 26 befindet sich in seiner untersten, unwirksamen Stellung und das Segment 27 in seiner Wirkstellung ganz oben. In dieser Ausgangslage gelangen somit die Patronen 13 zur Kanone 10.2-4, the two segments 26 and 27 are slidably arranged in a housing 28. For precise guidance of the segments 26 and 27 in the housing 28, four pins 30 are fastened in the housing base 29, which protrude into corresponding bores in the segments 26 and 27. At each end of the two segments 26 and 27, a pin 31 is fastened, which projects into a corresponding hole in two balance beams 32. The two balance beams 32 are pivotally mounted about bolts 33 in the housing 28 and have the task of lowering the other segment when lifting one segment. Two plate spring assemblies 34 endeavor to push the segment 26 out of its lowest position shown (FIG. 3) into its uppermost position. A cable 35, which is fastened to segment 26 with the aid of a screw 36, can pull segment 26 against the force of plate spring assemblies 34 into the lowest position shown. 3 and 4, the cable 35 is tensioned and the plate spring assemblies 34 are compressed. The segment 26 is in its lowest, inactive position and the segment 27 in its active position at the top. In this initial position, the cartridges 13 thus reach the cannon 10.

Gemäss Fig. 5 sind zwei Sternräder 16 und zwei Sternräder 17 an je einer Welle 40 bzw. 44 befestigt, welche sich im Gehäuse 15 (Fig. 1) zwischen zwei Wänden 37 und 38 befinden und über vier Kugellager 39 in diesen Wänden 37 und 38 gelagert sind. Die gemäss Fig.1 sich an Stelle E befindliche Patrone 13, wird gemäss Fig. 5 ausser durch die vier Sternräder 16 und 17 und durch eines der Segmente 26 oder 27 noch durch eine Scheibe 41 gehalten, welche in die Ausziehnut 42 der Patrone 13 eingreift. Das ist notwendig, damit die Patrone 13 nicht in Richtung des Pfeiles 43 umkippen kann, sobald sie bei Ihrem Transport aus der Stelle E in Richtung eines der Pfeile 24 und 25 nur noch von einem der beiden Sternräder 16 oder 17 gehalten ist.5, two star wheels 16 and two star wheels 17 are fastened to a shaft 40 and 44, respectively, which are located in the housing 15 (FIG. 1) between two walls 37 and 38 and via four ball bearings 39 in these walls 37 and 38 are stored. The cartridge 13 located at position E according to FIG. 1 is held according to FIG. 5 except by the four star wheels 16 and 17 and by one of the segments 26 or 27 by a disk 41 which engages in the extraction groove 42 of the cartridge 13 . This is necessary so that the cartridge 13 cannot tip over in the direction of the arrow 43 as soon as it is only held by one of the two star wheels 16 or 17 during its transport from the point E in the direction of one of the arrows 24 and 25.

Die Wirkungsweise der beschriebenen Überwachungseinrichtung ergibt sich aus der obigen Beschreibung wie folgt:The mode of operation of the monitoring device described results from the above description as follows:

Beim Einleiten eines Seriefeuers werden die Patronen 13 durch eine nicht dargestellte Fördervorrichtung von einem Munitionsbehälter zur Eintrittsöffnung 19 transportiert (Fig. 1) und vom Zuführrad 16 zur Stelle E gebracht. Da sich die beiden Segmente 26 und 27 in der in Fig. 3 gezeigten Ausgangsstellung befinden, werden die Patronen 13 anschliessend durch das Übergaberad 17 zur Stelle A (Fig. 1) gebracht (Pfeil 24). Von hier werden die Patronen 13 durch einen nicht dargestellten Verschluss in ein Waffenrohr 11 eingeschoben, anschliessend wird der Verschluss verriegelt. An der Stelle B (Fig. 1) wird die Patrone 13 gezündet. An der Stelle C (Fig. 1) wird die leera Patronenhülse aus dem Waffenrohr 11 herausgezogen und gelangt zur Stelle D (Fig. 1), an der sie vom Auswerferrad 18 erfasst und durch die zweite Austrittsöffnung 21 ausgestossen wird.When initiating a series fire, the cartridges 13 are transported by a conveyor device, not shown, from an ammunition container to the inlet opening 19 (FIG. 1) and brought to the point E by the feed wheel 16. Since the two segments 26 and 27 are in the starting position shown in FIG. 3, the cartridges 13 are then brought to position A (FIG. 1) by the transfer wheel 17 (arrow 24). From here, the cartridges 13 are inserted into a weapon barrel 11 through a breech, not shown, and the breech is then locked. At point B (Fig. 1), the cartridge 13 is ignited. At point C (FIG. 1), the empty cartridge case is pulled out of weapon barrel 11 and arrives at point D (FIG. 1), where it is gripped by ejector wheel 18 and ejected through second outlet opening 21.

Bei einer Zündverzögerung, d.h. wenn die Patrone 13 auf das Anstachen ihrer Zündkapsel nicht rechtzeitig anspricht, oder bei einem Spätzünder kann die Patronenhülse nicht wie vorgesehen an der Stelle C aus dem Waffenrohr 11 herausgezogen werden. An der Stelle C wird somit durch ein an sich bekanntes, hier nicht dargestelltes Tastorgan die Anwesenheit eines Spätzünders festgestellt und über das Kabel 35 (Fig. 2) werden die beiden Segmente 26 und 27 aus ihrer Ausgangsstellung gemäss Fig. 3 verschoben, d.h das eine Segment 26 gelangt in seine wirksame Stellung und das andere Segment 27 gelangt in seine unwirksame Stellung. Von der Stelle E gelangen somit die Patronen 13 nicht mehr zur Stelle A bei der Waffe 10, sondern werden entsprechend dem Pfeil 25 durch das Zuführrad 16 zur ersten Austrittsöffnung 20 transportiert.With an ignition delay, i.e. if the cartridge 13 does not respond to the pricking of its primer in time, or in the case of a late bloomer, the cartridge case cannot be pulled out of the gun barrel 11 at point C as intended. At point C, the presence of a late bloomer is thus determined by a sensing element known per se, not shown here, and the two segments 26 and 27 are displaced from their starting position according to FIG. 3 via cable 35 (FIG. 2), ie one Segment 26 comes into its active position and the other segment 27 comes into its ineffective position. From the point E, the cartridges 13 no longer reach the point A at the weapon 10, but are transported according to the arrow 25 through the feed wheel 16 to the first outlet opening 20.

Unabhängig davon, ob die Patronen gemäss Pfeil 24 zur Stelle A oder gemäss Pfeil 25 zur Austrittsöffnung 20 gelangen, werden sie gemäss Fig. 5 durch die Scheibe 41 gehalten, welche in die Ausziehnut 42 hineinragt. Ein Kippen der Patrone 13 in Richtung des Pfeiles 43 (Fig. 5) wird somit zuverlässig verhindert.Regardless of whether the cartridges reach point A according to arrow 24 or to outlet opening 20 according to arrow 25, they are held according to FIG. 5 by the disk 41, which projects into the extraction groove 42. Tilting of the cartridge 13 in the direction of arrow 43 (FIG. 5) is thus reliably prevented.

Claims (7)

1. A hang-fire control means for an externally powered gun (10), having an ammunition feed enclosure (15) in which a set of deflecting means (26,27) is displaceably mounted, which whenever ignition is delayed deflects the cartridges (13) supplied to the gun (10) into an ejector passage (20) and they remain on an endless chain, characterised in that the deflecting means comprise two segments (26, 27) which can be displaced in the direction of the cartridge axes and one of which selectively projects as required into the path of the cartridges (13).
2. The hang-fire control means according to Claim 1, characterised in that the two segments (26, 27) are hinged at the ends of a balance arm (32) pivotably mounted in an enclosure (28), in order to necessarily displace the two segments (26, 27) in opposite directions.
3. The hang-fire control means according to Claim 2, characterised in that at least one compression spring (34) is supported on the one on one segment (26) and on the other on the enclosure (28) and tries to push one segment (26) into its operational position and the other segment (27) into its nonoperational position.
4. The hang-fire control means according to Claim 3, characterised in that to actuate the segments (26, 27) an actuating cable (35) is fixed on one segment (26) in order to push said segment (26) against the force of the compression spring (34) into its non-operational position.
5. The hang-fire control means according to Claim 4, characterised in that to guide the segments (26, 27) pilot pins (30) are fixed in the enclosure (28) which project into holes in the segments (26,27), which can be displaced on said pins (30).
6. The hang-fire control means according to Claim 1, characterised in that in its operational position one of the segmenta (27) projects into the ejector passage (20) and the other segment (26) projects in its operational position into the feeder passage (19).
7. The hang-fire control means according to Claim 1, charactersised in that in the region of the segments (26, 27) is arranged a rotating plate (41) which engages in the cannelure of the cartridges (13) to prevent the cartridges from overturning.
