Abstract

When feeding cartridges (20) from a container (13) to a firearm (10), there are problems if three requirements are intended to be met simultaneously, namely:   a) the first cartridge (20) of a firing sequence is not intended to be fed until the acceleration of the weapon (10) has been completed;   b) the last cartridge (20) of the firing sequence is intended to be fed before the weapon (10) has been braked;   c) the empty cartridge cases (33) are intended to be fed back by means of the feed device to the container (13). <??>This object is achieved by means of the additional arrangement of an   a) endless storage chain (34),   b) a transfer point (36),   c) a switching point (37) which can be switched over, in order to store empty cartridge cases (33) temporarily during the return of the transportation device. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Zuführen von Patronen zu einer Feuerwaffe, insbesondere eine Mehrrohrkanone mit einem rotierenden Rohrbündel, aus einem an dieser Waffe befestigten Munitionsbehälter nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for supplying cartridges to a firearm, in particular a multi-barrel cannon with a rotating tube bundle, from an ammunition container attached to this weapon according to the preamble of claim 1.

Bei einer bekannten Patronenzuführvorrichtung dieser Art (EP-A-020 095) ist ein Speicher für die Patronen vorhanden. Eine Transportkette wird durch einen Zuführkanal und durch einen Rückführkanal hindurchgeführt. Der Zuführkanal mündet in eine Übergabestation der Feuerwaffe. An der Übergabestelle vom Zuführkanal zum Speicherkanal befindet sich eine Weiche. In einer Stellung dieser Weiche gelangt die Munition aus dem Zuführkanal auf eine zweite Transportkette, welche zur Übergabestation der Feuerwaffe führt. In der anderen Stellung dieser Weiche gelangt die Munition auf der Transportkette durch den Speicherkanal in den Rückführkanal. Durch einen Schalter, der mit der Waffe verbunden ist, kann die Weiche umgeschaltet werden, von ihrer ersten Stellung in ihre zweite Stellung. Die Übergabestation der Waffe dreht sich weiter vorwärts, bis alle Patronen aus der zweiten Transportkette entfernt wurden. Die erste Transportkette bewegt sich weiter vorwärts und bringt die Munition in den Speicherkanal. Eine Umkehrvorrichtung bewegt anschliessend die erste Transportkette rückwärts, bis die Munition aus dem Speicherkanal wieder in den Zuführkanal gelangt ist, während sich die Übergabestation vollständig entleert. Somit kann die vorübergehend im Speicherkanal enthaltene Munition beim nächsten Feuerstoss der Waffe zugeführt werden.In a known cartridge supply device of this type (EP-A-020 095) there is a memory for the cartridges. A transport chain is passed through a feed channel and through a return channel. The feed channel opens into a firearm transfer station. There is a switch at the transfer point from the feed channel to the storage channel. When this switch is in position, the ammunition passes from the feed channel onto a second transport chain which leads to the firearm transfer station. In the other position of this switch, the ammunition on the transport chain passes through the storage channel into the return channel. The switch can be switched from its first position to its second position by a switch connected to the weapon. The weapon transfer station continues to rotate until all cartridges have been removed from the second transport chain. The first transport chain continues to move and brings the ammunition into the storage channel. A reversing device then moves the first transport chain backwards until the ammunition out of the Storage channel has returned to the feed channel while the transfer station is completely emptied. The ammunition temporarily contained in the storage channel can thus be supplied to the weapon during the next round of fire.

Bei einer Mehrrohrkanone, die sich auf einem Fahrzeug befindet, ist es oft nicht erwünscht, dass die leeren Patronenhülsen einfach ausgeworfen werden. Falls diese leeren Hülsen mit derselben Vorrichtung, die zum Zuführen der Patronen dient, auch wieder in das Patronenmagazin zurückgeführt werden sollen, können sich Probleme mit dem sogenannten Hochlauf der Waffe ergeben.With a multi-tube cannon that is on a vehicle, it is often not desirable that the empty cartridge cases are simply ejected. If these empty sleeves are to be returned to the cartridge magazine with the same device that is used to feed the cartridges, problems can arise with the so-called ramp-up of the weapon.

Die Aufgabe, welche mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung einer Vorrichtung zum Zuführen von Patronen zu einer Feuerwaffe, mit welcher die leeren Patronenhülsen von der Feuerwaffe weggeführt werden können, wobei die Patronen einem Munitionsbehälter entnommen und die leeren Hülsen demselben Munitionsbehälter zugeführt werden, wobei die erste Patrone erst nach Beendigung des Waffenhochlaufes der Feuerwaffe zugeführt wird und bei Beendigung des Feuerstosses beim Anhalten der Waffe weitere Patronen zugeführt werden, die jedoch nicht mehr abgefeuert werden, sondern wie die leeren Hülsen zum Munitionsbehälter zurückgeführt werden. Es soll also nicht nur der erste Schuss eines Feuerstosses nach dem Hochlauf der Waffe abgefeuert werden, sondern auch der letzte Schuss des Feuerstosses soll noch vor dem Abbremsen der Waffe abgefeuert werden.The object to be achieved with the present invention is to provide a device for supplying cartridges to a firearm, with which the empty cartridge cases can be guided away from the firearm, the cartridges being removed from an ammunition container and the empty cartridges being the same ammunition container are fed, the first cartridge being fed to the firearm only after the firing of the gun has ended and further cartridges being fed in when the firing is stopped when the gun is stopped, but these are no longer fired but are returned to the ammunition container like the empty cartridges. So not only should the first shot of a burst of fire be fired after the gun has started up, but also the last shot of the burst of fire should be fired before the weapon is braked.

Diese Aufgabe wird durch die im Kennzeichen des Patentanspruchs 1 gegebene Lehre gelöst.This object is achieved by the teaching given in the characterizing part of patent claim 1.

Gemäss Fig.1-3 befinden sich unter einer Gatlingkanone 10 - mit beispielsweise sieben Waffenrohren 11 - drei Munitionsbehälter 12,13 und 14, von denen in Fig.1 nur der mittlere Munitionsbehälter 13 sichtbar ist. Die Gatlingkanone 10 gehört nicht zum Erfindungsgegenstand und ist daher hier nicht näher beschrieben. Wesentlich ist hier lediglich, dass diese Kanone ein rotierendes Rohrbündel 15 aufweist, das die genannten sieben Waffenrohre 11 enthält. Mit einem solchen rotierenden Rohrbündel 15 soll der erste Schuss erst abgefeuert werden, wenn das rotierende Rohrbündel 15 sich mit der gewünschten Nenndrehzahl dreht. Mit anderen Worten, während der sogenannten Hochlaufzeit der Waffe soll nicht geschossen werden, d.h. es soll während dieser Zeit noch keine Patrone der Waffe 10 zugeführt werden. Während der Hochlaufzeit der Feuerwaffe soll auch die Patronenzufuhr auf die erforderliche Kadenz beschleunigt werden - wie weiter unten noch beschrieben ist -, ohne dass jedoch - wie gesagt - eine Patrone der Waffe zugeführt wird.According to FIG. 1-3 there are three ammunition containers 12, 13 and 14 under a Gatling cannon 10 - with for example seven weapon tubes 11 -, of which only the middle ammunition container 13 is visible in FIG. The Gatling cannon 10 is not part of the subject matter of the invention and is therefore not described in more detail here. It is only essential here that this cannon has a rotating tube bundle 15, which contains the seven weapon tubes 11 mentioned. With such a rotating tube bundle 15, the first shot should only be fired when the rotating tube bundle 15 rotates at the desired nominal speed. In other words, the weapon should not be fired during the so-called ramp-up time, ie it should be during this time, no cartridge of the weapon 10 can be fed. During the run-up time of the firearm, the cartridge feed should also be accelerated to the required cadence - as will be described further below - without, however, as stated, a cartridge being fed to the weapon.

Gemäss Fig.3 sind an einem Sockel 16 zwei Tragarme 17 und 18 befestigt, zwischen denen die Gatlingkanone 10 um eine Elevationsachse 42 schwenkbar gelagert ist. Die drei Munitionsbehälter 12,13 und 14 sind an der Waffe 10 befestigt und lassen sich mit der Waffe 10 um die Elevationsachse 42 verschwenken.According to FIG. 3, two support arms 17 and 18 are fastened to a base 16, between which the Gatling gun 10 is pivotably mounted about an elevation axis 42. The three ammunition containers 12, 13 and 14 are fastened to the weapon 10 and can be pivoted about the elevation axis 42 with the weapon 10.

Gemäss Fig.1 befindet sich zwischen dem Waffenrohrbündel 15 mit den sieben Waffenrohren 11 und den drei Munitionsbehältern 12,13 und 14 eine Transportvorrichtung 19, mit welcher - wie aus Fig.2 ersichtlich - abwechselnd Patronen 20 aus den seitlichen beiden Munitionsbehältern 12 und 14 dem mittleren Munitionsbehälter 13 zugeführt werden. Gemäss Fig.2 werden die Patronen 20 an der Stelle 21 dem seitlichen Behälter 14 und an der Stelle 22 dem anderen seitlichen Behälter 12 entnommen und von der Transportvorrichtung 19 an der Stelle 23 dem mittleren Behälter 13 zugeführt. Die Transportvorrichtung 19 weist gemäss Fig.1 und 2 zwei endlose Transportketten oder Transportbänder 24 und 25 auf, von denen sich die eine Transportkette 24 von der Stelle 21 zur Stelle 23 erstreckt und von denen sich die andere Transportkette 25 von der Stelle 22 ebenfalls zur Stelle 23 erstreckt. Diese beiden Transportketten 24 und 25 greifen an der Stelle 23 derart ineinander ein, dass dem mittleren Behälter 13 abwechselnd je eine Patrone 20 aus dem einen seitlichen Behälter 12 und dann aus dem anderen seitlichen Behälter 14 zugeführt wird. Im mittleren Behälter 13 befindet sich eine endlose Speicherkette 26, welche über mehrere Umlenkrollen 27 geführt ist. Mit dieser Speicher- und Förderkette 26 gelangen die Patronen 20, wie durch Pfeile A angedeutet, von der Stelle 23 zu einer Übergabestelle 28. An dieser Übergabestelle gelangen die Patronen 20 von der Speicherkette 26 auf eine Zuführkette 29, mit welcher die Patronen der Waffe 10 zugeführt werden, wie aus Fig.8 ersichtlich ist. Gemäss Fig.1 sind jedoch die Patronen 20 in den drei Munitionsbehältern 12,13 und 14 quer zu den Waffenrohren 11 angeordnet und müssen daher durch die Zuführkette 29 um 90° gedreht werden. Die Zuführkette 29 ist daher flexibel ausgebildet und lässt sich in der erforderlichen Weise verdrehen. Diese Verdrehung ist jedoch der Deutlichkeit halber in Fig.8 und den folgenden Figuren nicht dargestellt. Somit ist die Zuführkette 29 unten um eine Umlenkrolle 30 und oben um eine Umlenkrolle 31 geführt, die rechtwinklig zueinander gerichtet sind. Gemäss Fig.1 erfolgt diese Verdrehung in einem Gehäuse 32.According to FIG. 1, between the weapon barrel bundle 15 with the seven weapon tubes 11 and the three ammunition containers 12, 13 and 14, there is a transport device 19 with which, as can be seen from FIG. 2, cartridges 20 alternately from the two ammunition containers 12 and 14 on the side middle ammunition container 13 are supplied. According to FIG. 2, the cartridges 20 are removed from the side container 14 at the point 21 and from the other side container 12 at the point 22 and fed to the middle container 13 by the transport device 19 at the point 23. 1 and 2, the transport device 19 has two endless transport chains or conveyor belts 24 and 25, of which one transport chain 24 extends from point 21 to point 23 and from which the other transport chain 25 also extends from point 22 to position 23 extends. These two transport chains 24 and 25 engage in one another at point 23 such that a cartridge 20 is alternately fed from the one side container 12 and then from the other side container 14 to the middle container 13. In the middle container 13 there is an endless storage chain 26 which is guided over a plurality of deflection rollers 27. With this storage and conveyor chain 26, the cartridges 20, as indicated by arrows A, from the point 23 to a transfer point 28. At this transfer point, the cartridges 20 arrive from the storage chain 26 on a feed chain 29 with which the cartridges are fed to the weapon 10, as can be seen from FIG. 1, however, the cartridges 20 are arranged in the three ammunition containers 12, 13 and 14 transversely to the weapon tubes 11 and must therefore be rotated through 90 ° by the feed chain 29. The feed chain 29 is therefore flexible and can be rotated in the required manner. For the sake of clarity, however, this twist is not shown in FIG. 8 and the following figures. The feed chain 29 is thus guided at the bottom around a deflection roller 30 and at the top around a deflection roller 31 which are directed at right angles to one another. According to FIG. 1, this rotation takes place in a housing 32.

Mit der Zuführkette 29 sollen aber nicht nur die Patronen 20 der Waffe 10 zugeführt werden, sondern gleichzeitig sollen die leeren Patronenhülsen 33 aus der Waffe 10 in die Munitionsbehälter 12,13 und 14 zurückbefördert werden. Gemäss Fig.10 werden die Patronen 20 in Richtung des Pfeiles A auf der einen Seite der endlosen Zuführkette 29 zugeführt und die leeren Hülsen 33 werden in Richtung der Pfeiles A auf der anderen Seite der endlosen Zuführkette 29 weggeführt. Neben der endlosen Förderkette 29 befindet sich gemäss Fig.1 und 10 eine weitere endlose Speicherkette 34, welche um fünf Umlenkräder 35 geführt ist. An einer Übergabestelle 36 können die Patronen 20 oder die leeren Hülsen 33 von der Speicher- und Förderkette 26 auf die Speicherkette 34 gelangen, wenn sich die Speicher- und Förderkette 26 in Richtung des Pfeiles B bewegt.With the feed chain 29, however, not only are the cartridges 20 of the weapon 10 to be fed, but at the same time the empty cartridge cases 33 are to be returned from the weapon 10 into the ammunition containers 12, 13 and 14. 10, the cartridges 20 are fed in the direction of arrow A on one side of the endless feed chain 29 and the empty sleeves 33 are led away in the direction of arrow A on the other side of the endless feed chain 29. In addition to the endless conveyor chain 29, there is a further endless storage chain 34 according to FIGS. At a transfer point 36, the cartridges 20 or the empty sleeves 33 can get from the storage and conveyor chain 26 to the storage chain 34 when the storage and conveyor chain 26 moves in the direction of arrow B.

Die Ausbildung dieser Übergabestelle 36 ist im folgenden anhand der Figuren 4-7 näher erläutert. An dieser Übergabestelle 36 ist eine Weiche 37, bestehend aus im wesentlichen zwei Umlenkorganen 38 und 39, angeordnet. Falls diese Weiche 37 sich in der Stellung gemäss Fig.4 befindet, bleiben die Patronen 20 und die leeren Hülsen auf der Speicher- Förderkette 26 unabhängig davon, in welcher Richtung sich diese Speicher- und Förderkette 26 bewegt. Falls jedoch die Weiche 37 sich in der Stellung gemäss Fig.7 befindet, gelangen die leeren Hülsen 33 von der Speicher- und Förderkette 26 auf die Speicherkette 34, die weiter unten auch als Hülsenschlaufe bezeichnet ist. Dies ist jedoch nur möglich, wenn sich die Speicher- und Förderkette 26 in Richtung des Pfeiles B bewegt.The design of this transfer point 36 is explained in more detail below with reference to FIGS. 4-7. At this transfer point 36 there is a switch 37, consisting essentially of two deflection elements 38 and 39. If this switch 37 is in the position according to FIG. 4, the cartridges 20 and the empty sleeves remain on the storage conveyor chain 26 regardless of the direction in which this storage and conveyor chain 26 moves. However, if the switch 37 is in the position according to FIG. 7, the empty sleeves 33 pass from the storage and conveyor chain 26 to the storage chain 34, which is also referred to below as a sleeve loop. However, this is only possible if the storage and conveyor chain 26 moves in the direction of arrow B.

Anhand der Figuren 8-15 soll die Bedeutung dieser Speicherkette 34 erläutert werden.The meaning of this memory chain 34 will be explained with reference to FIGS. 8-15.

Gemäss Fig.8 befindet sich die erste Patrone 20, die beim Schiessen zur Feuerwaffe 10 gelangt, im Bereich eines Tastorganes 40. Sobald die Kanone 10 für Einzelschuss oder Seriefeuer eingeschaltet wird, gelangt diese erste Patrone 20 von der Speicher- und Förderkette 26 auf die Zuführkette 29 und zur Kanone 10, wie aus Fig.9 ersichtlich. Bis die erste Patrone 20 diesen Weg zurückgelegt hat, ist sowohl der Hochlauf der Gatlingkanone 10 als auch der Hochlauf der Zuführvorrichtung beendet, d.h. die Speicher- und Förderkette 26 als auch die Zuführkette 29 bewegen sich mit der für ein Seriefeuer erforderlichen Kadenz. Die Patronen 20, die sich in der Speicherkette 34 (siehe Fig.8) befanden, sind während des Hochlaufes der Kanone 10 und der Zuführvorrichtung in die Speicher- und Förderkette 26 gelangt (siehe Fig.9). Zu Beginn eines Seriefeuers, d.h. beim ersten Schuss eines ersten Feuerstosses, ist somit die Speicherkette 34 leer.According to FIG. 8, the first cartridge 20, which reaches the firearm 10 when firing, is located in the region of a sensing element 40. As soon as the cannon 10 is switched on for single-shot or series fire, this first cartridge 20 passes from the storage and conveyor chain 26 onto the Feed chain 29 and to the cannon 10, as shown in Fig.9. By the time the first cartridge 20 has traveled this distance, both the run-up of the Gatling cannon 10 and the run-up of the feed device have ended, i.e. the storage and conveyor chain 26 as well as the feed chain 29 move with the cadence required for a series fire. The cartridges 20, which were in the storage chain 34 (see FIG. 8), entered the storage and conveyor chain 26 during the run-up of the cannon 10 and the feed device (see FIG. 9). At the start of a series fire, i.e. with the first shot of a first burst of fire, the storage chain 34 is thus empty.

Gemäss Fig.10 werden während eines Seriefeuers durch die endlose Förderkette 29 einerseits Patronen 20 der Kanone 10 zugeführt und gleichzeitig leere Hülsen 33 der Speicher- und Förderkette 26 zugeführt. Aus Fig.10 ist weiterhin ersichtlich, dass während eines Seriefeuers keine Patrone 20 oder leere Hülsen 33 auf die Speicherkette 34 gelangen. Die Weiche 37 befindet sich während eines Seriefeuers in der Stellung gemäss Fig.4.According to FIG. 10, cartridges 20 are fed to the cannon 10 during a series fire through the endless conveyor chain 29, and empty sleeves 33 are simultaneously fed to the storage and conveyor chain 26. FIG. 10 also shows that no cartridge 20 or empty sleeves 33 get onto the storage chain 34 during a series fire. The Switch 37 is in the position according to Fig. 4 during a series fire.

Bei Beendigung eines Feuerstosses bleibt die Kanone 10 nicht sofort stehen, sondern läuft infolge ihrer grossen Trägheit weiter, somit gelangen, wie aus Fig.11 ersichtlich, Patronen 20 auf den sich nach unten bewegenden Teil der Zuführkette 29. Sobald die Kanone 10 vollständig zum Stillstand gekommen ist, befindet sich, gemäss Fig.11, die erste Patrone 20 im Bereich der Weiche 37 und ebenso befindet sich die leere Hülse 33 der zuletzt verschossenen Patrone 20 im Bereich dieser Weiche 37.When a burst of fire ends, the cannon 10 does not stop immediately, but continues to run due to its great inertia, so, as can be seen from FIG. 11, cartridges 20 reach the downwardly moving part of the feed chain 29. As soon as the cannon 10 stops completely 11, the first cartridge 20 is located in the area of the switch 37 and likewise the empty sleeve 33 of the cartridge 20 that was last fired is located in the area of this switch 37.

Gemäss Fig.12 müssen die Patronen 20 wieder zurücktransportiert werden. Zu diesem Zweck bewegen sich die Speicher- und Förderkette 26, die Zuführkette 29 und auch die Speicherkette 34 in entgegengesetzter Richtung, wie durch die Pfeile B angedeutet wird. Gleichzeitig ist die Weiche 37 umgeschaltet worden. Die leeren Hülsen 33 gelangen jetzt auf Speicherkette 34, daher wird diese Kette 34 auch als Hülsenschlaufe bezeichnet. Die Patronen 20 gelangen nun von der Weiche 37 zur Waffe 10, ohne dass sie dort verschossen werden.According to FIG. 12, the cartridges 20 have to be transported back again. For this purpose, the storage and conveyor chain 26, the feed chain 29 and also the storage chain 34 move in the opposite direction, as indicated by the arrows B. At the same time the switch 37 has been switched. The empty sleeves 33 now arrive on the storage chain 34, which is why this chain 34 is also referred to as a sleeve loop. The cartridges 20 now pass from the switch 37 to the weapon 10 without being fired there.

Gemäss Fig.13 ist dieser Rücklauf beendet, wenn sich die erste Patrone 20 wieder im Bereich des Tastorganes 40 befindet. Die leeren Hülsen 33 haben bei diesem Rücklauf den grösseren Teil der Speicherkette 34 angefüllt. Ohne diese Hülsenschlaufe wäre der beschriebene Rücklauf nicht möglich, da sonst leere Hülsen 33 der Feuerwaffe 10 hätten zugeführt werden müssen, was nicht sehr sinnvoll ist, da die Kanone beim nochmaligen Zuführen der Hülsen eine zusätzliche unnötige Belastung erfahren würde und sich nach jedem Feuerstoss Hülsen in der Kanone befinden, die bei einer allfälligen Wartung zuerst entfernt werden müssten, was einen zusätzlichen Zeitaufwand bedeutet. Mit der Hülsenschlaufe 34 lassen sich diese zusätzlichen Belastungen der Kanone vermeiden.According to FIG. 13, this return is ended when the first cartridge 20 is again in the area of the sensing element 40. The empty sleeves 33 have filled the greater part of the storage chain 34 during this return. Without this sleeve loop, the return described would not be possible, since otherwise empty sleeves 33 would have had to be fed to the firearm 10, which is not very useful since the cannon would experience an additional unnecessary load when the sleeves were fed again, and sleeves would get in after each burst of fire the cannon, which would have to be removed for any maintenance, which means an additional expenditure of time. With the Sleeve loop 34 can avoid these additional loads on the cannon.

Gemäss Fig.14 wird der erste Schuss des zweiten Feuerstosses erst abgefeuert, wenn die erste Patrone 20 wiederum vom Tastorgan 40 bis zur Kanone 10 gelangt ist. In dieser Zeit hat sich die Speicherkette oder Hülsenschlaufe 34 wieder teilweise von den Hülsen 33 entleert. Gemäss Fig.15 gelangt die letzte Hülse 33 des ersten Feuerstosses aus der Hülsenschlaufe 34 direkt neben die erste Hülse 33 des zweiten Feuerstosses in der Speicher- und Förderkette 26 des Patronenmagazins.According to FIG. 14, the first shot of the second burst of fire is not fired until the first cartridge 20 has in turn reached from the sensing element 40 to the cannon 10. During this time, the storage chain or sleeve loop 34 has partially emptied again from the sleeves 33. According to FIG. 15, the last sleeve 33 of the first burst of fire arrives from the sleeve loop 34 directly next to the first sleeve 33 of the second burst of fire in the storage and conveyor chain 26 of the cartridge magazine.

Gemäss Fig.4-7 besteht die Weiche 37 aus einem verschwenkbaren Umlenkorgan 38 und einem verschiebbaren Umlenkorgan 39. Ferner ist an der Übergabestelle 36 ein Förderstern 41 angeordnet, der sich im Gegenuhrzeigersinne dreht, wenn die Patronen 20 in Richtung des Pfeiles A der Feuerwaffe 10 zugeführt werden und der sich im Uhrzeigersinne dreht, wenn die Patronen 20 in Richtung des Pfeiles B zurücktransportiert werden.According to FIGS. 4-7, the switch 37 consists of a pivotable deflection element 38 and a displaceable deflection element 39. Furthermore, a conveying star 41 is arranged at the transfer point 36, which rotates counterclockwise when the cartridges 20 in the direction of arrow A of the firearm 10 are supplied and which rotates clockwise when the cartridges 20 are transported back in the direction of arrow B.

Die Wirkungsweise der beschriebenen Patronenzuführvorrichtung ist wie folgt: Bevor mit der Waffe 10 der erste Schuss eines Feuerstosses abgefeuert wird, befinden sich die Patronen 20 in der Ausgangsposition gemäss Fig.8 und Fig.1. Sobald der Abzug der Feuerwaffe 10 betätigt wird, beginnt sich die Speicher- und Förderkette 26 in Richtung der Pfeile A (Fig.1 und 8) zu bewegen. Gleichzeitig bewegt sich auch die Zuführkette 29 und die Speicherkette 34 in Richtung der Pfeile A. Durch diese Bewegung gelangt einerseits die erste Patrone 20 zur Waffe 10 und andererseits werden Patronen 20 aus der Speicherkette 34 in die Speicher- und Förderkette 26 transportiert, wie aus Fig.9 ersichtlich ist. Sobald die erste Patrone 20 zur Waffe 10 gelangt ist, kann der erste Schuss abgefeuert werden. Während des ersten Feuerstosses gelangen dann die leeren Hülsen 33 über die Zuführkette 29 in die Speicher- und Förderkette 26, wie aus Fig.10 ersichtlich ist. Bei Beendigung des ersten Feuerstosses gelangen weder die Waffe noch die Patronenzuführvorrichtung sofort zum Stillstand, daher werden gemäss Fig.11 eine Anzahl Patronen 20 über die Zuführkette 29 zur Speicher- und Förderkette 26 weitergefördert. Gemäss Fig.12 und 13 müssen nun nach dem Stillstand sowohl die Speicher- und Förderkette 26, die Zuführkette 29 als auch die Speicherkette 34 in Richtung der Pfeile B zurückbewegt werden, bis die erste Patrone 20 sich wieder in ihrer Ausgangslage im Bereich des Tastorganes 40 befindet. Bei dieser Rückwärtsbewegung der drei Ketten 26,29 und 34 muss verhindert werden, dass leere Patronenhülsen 33 in die Waffe 10 gelangen. Zu Beginn der Rückwärtsbewegung der drei Ketten 26,29 und 34 muss daher die Weiche 37 an der Umlenkstelle 36 in die Stellung gemäss Fig.7 gebracht werden.The mode of operation of the cartridge supply device described is as follows: before the first shot of a firing burst is fired with the weapon 10, the cartridges 20 are in the starting position according to FIGS. 8 and 1. As soon as the trigger of the firearm 10 is actuated, the storage and conveyor chain 26 begins to move in the direction of the arrows A (FIGS. 1 and 8). At the same time, the feed chain 29 and the storage chain 34 also move in the direction of the arrows A. This movement, on the one hand, brings the first cartridge 20 to the weapon 10 and, on the other hand, cartridges 20 are transported from the storage chain 34 into the storage and conveyor chain 26, as shown in FIG .9 can be seen. As soon as the first cartridge 20 has reached the weapon 10, the first shot can be fired. During the first burst of fire the empty sleeves 33 then reach the storage and conveyor chain 26 via the feed chain 29, as can be seen from FIG. When the first burst of fire ends, neither the weapon nor the cartridge feeder immediately comes to a standstill, therefore a number of cartridges 20 are conveyed further via the feed chain 29 to the storage and conveyor chain 26 according to FIG. According to FIGS. 12 and 13, after the standstill, both the storage and conveyor chain 26, the supply chain 29 and the storage chain 34 must be moved back in the direction of the arrows B until the first cartridge 20 is again in its starting position in the region of the sensing element 40 located. During this backward movement of the three chains 26, 29 and 34, it must be prevented that empty cartridge cases 33 get into the weapon 10. At the beginning of the backward movement of the three chains 26, 29 and 34, the switch 37 at the deflection point 36 must therefore be brought into the position according to FIG.

Wie aus Fig.12 und 13 ersichtlich, gelangen somit bei der Rückwärtsbewegung der drei Ketten 26,29 und 34 die leeren Patronenhülsen 33 in die Speicherkette 34. Sobald nun ein zweiter Feuerstoss abgegeben werden soll und der Abzug der Waffe 10 betätigt wird, dann bewegen sich alle drei Ketten wieder in Richtung der Pfeile A. Sobald gemäss Fig.14 die erste Patrone 20 die Waffe 10 erreicht hat, ist bereits ein Teil der leeren Hülsen 33 wieder von der Speicherkette 34 auf die Förder- und Speicherkette 26 transportiert worden. Sobald gemäss Fig.15 während des zweiten Feuerstosses die erste leere Hülse 33 zur Umlenkstelle 36 gelangt, wird auch die letzte leere Hülse 33 des ersten Feuerstosses aus der Speicherkette 34 in die Förder- und Speicherkette 26 zurücktransportiert. Wie oben bereits erwähnt, gelangt die letzte Hülse 33 des ersten Feuerstosses aus der Hülsenschlaufe 34 direkt neben die erste Hülse 33 des zweiten Feuerstosses in der Speicher- und Förderkette 26 des Munitionsbehälters 13.As can be seen from FIGS. 12 and 13, when the three chains 26, 29 and 34 move backward, the empty cartridge cases 33 enter the storage chain 34. As soon as a second burst of fire is to be emitted and the trigger of the weapon 10 is actuated, then move all three chains again in the direction of arrows A. As soon as the first cartridge 20 has reached the weapon 10 according to FIG. 14, part of the empty sleeves 33 has already been transported from the storage chain 34 to the conveyor and storage chain 26 again. As soon as the first empty sleeve 33 arrives at the deflection point 36 during the second burst of fire, the last empty sleeve 33 of the first burst of fire is also transported back from the storage chain 34 into the conveyor and storage chain 26. As already mentioned above, the last sleeve 33 of the first shot of fire arrives from the sleeve loop 34 directly next to the first sleeve 33 of the second shot of fire in the storage and conveyor chain 26 of the ammunition container 13.
