Description

Die Erfindung betrifft eine Fördervorrichtung zum Zuführen von Patronen zu einer Feuerwaffe aus einem Trommelmagazin, das in eine Anzahl Sektoren unterteilt ist, in denen sich je eine Patronenreihe befindet, mit einer ersten Fördervorrichtung, welche die Patronenreihen nacheinander aus den Sektoren des Trommelmagazins herausschiebt und mit einer zweiten Fördervorrichtung zum Transport der aus den Sektoren herausgeschobenen Patronen zur Feuerwaffe.The invention relates to a conveyor device for supplying cartridges to a firearm from a drum magazine, which is divided into a number of sectors, in each of which there is a row of cartridges, with a first conveyor device which pushes the cartridge rows out of the sectors of the drum magazine and with one second conveyor for transporting the cartridges pushed out of the sectors to the firearm.

Bei einer bekannten Fördervorrichtung dieser Art (siehe DE-B-1 026 201) besteht die erste Fördervorrichtung aus einer umlaufenden, mit Mitnehmern versehenen, endlosen Kette, die in Antriebsverbindung mit dem rotierenden Trommelmagazin steht. Von dieser ersten Fördervorrichtung gelangen die Patronen in eine in Antriebsverbindung mit ihr stehende zweite Fördervorrichtung, bestehend aus einer Förderscheibe, die ihrerseits die Patronen in die Waffe befördert.In a known conveyor device of this type (see DE-B-1 026 201), the first conveyor device consists of an encircling, endless chain provided with drivers, which is in drive connection with the rotating drum magazine. From this first conveying device, the cartridges pass into a second conveying device, which is in drive connection with it and consists of a conveyor disk, which in turn transports the cartridges into the weapon.

Diese bekannte Fördervorrichtung ist nachteilig, falls die Patronen oben oder auf der Seite dem Trommelmagazin entnommen werden sollen, da dann die Gefahr besteht, dass die Patronen in die leeren Sektoren des Trommelmagazins zurückfallen. Ferner ergeben sich bei hohen Kadenzen Schwierigkeiten bei der Uebergabe der Patronen von der ersten Fördervorrichtung in die zweite Fördervorrichtung. Es sind ferner bei dieser bekannten Vorrichtung - bei hohen Kadenzem - grosse Beschleunigungskräfte erforderlich, um eine ganze Patronenreihe plötzlich aus dem Stillstand zu beschleunigen.This known conveyor device is disadvantageous if the cartridges are to be removed from the drum magazine at the top or on the side, since there is then the risk that the cartridges fall back into the empty sectors of the drum magazine. Furthermore, with high cadences, difficulties arise in the transfer of the cartridges from the first conveyor to the second conveyor. In this known device - with high cadence - large acceleration forces are required to suddenly accelerate an entire row of cartridges from a standstill.

Die Aufgabe, die mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung einer Fördervorrichtung, welche auch bei hohen Kadenzen einen zuverlässigen Transport der Patronen vom Trommelmagazin zur Feuerwaffe gewährleistet. Insbesondere sollen keine grossen Beschleunigungskräfte auftreten, wenn eine Patronenreihe aus einem Sektor ausgeschoben wird, d. h. die Patronenreihe soll sanft aus dem Stillstand auf die erforderliche Geschwindigkeit beschleunigt werden.The object that is to be achieved with the present invention is to create a conveyor device which ensures reliable transport of the cartridges from the drum magazine to the firearm even at high cadences. In particular, no large acceleration forces should occur when a row of cartridges is ejected from a sector, i. H. the row of cartridges should be gently accelerated from standstill to the required speed.

Die Vorrichtung, mit der diese Aufgabe gelöst wird, ist durch zwei Merkmale gekennzeichnet :

  • a) Eine Rücklaufsperre ist zwischen den beiden Fördervorrichtungen angeordnet, um zu verhindern, dass Patronen in die bereits entleerten Sektoren hineinfallen.
  • b) Die erste Fördervorrichtung weist eine Förderschnecke auf, deren erste Windung eine kleinere Steigung besitzt als die übrigen Windungen. um die reihenweise Beschleunigung der im Trommelmagazin stillstehenden Patronen zu erleichtern.
The device with which this object is achieved is characterized by two features:
  • a) A backstop is arranged between the two conveyors to prevent cartridges from falling into the already empty sectors.
  • b) The first conveyor has a screw conveyor, the first turn of which has a smaller pitch than the other turns. to facilitate the row-by-row acceleration of the cartridges standing in the drum magazine.

Diese Vorrichtung hat den Vorteil, dass dank der Rücklaufsperre ein Abstand zwischen der stillstehenden Patronenreihe und der zweiten Fördervorrichtung vorhanden ist, der eine sanfte Beschleunigung dieser Patronenreihe gewährleistet. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.This device has the advantage that, thanks to the backstop, there is a distance between the stationary row of cartridges and the second conveyor device, which ensures a smooth acceleration of this row of cartridges. Further refinements result from the subclaims.

Gemäss Fig. 1 werden die Patronen 11 aus einem Trommelmagazin 10 über einen Förderkanal 12 eine Feuerwaffe 13 zugeführt. Die Feuerwaffe 13 ist in Fig. 1 in drei verschiedenen Elevationsstellungen gezeigt. In der mittleren Stellung sind die Waffenrohre 14 der Feuerwaffe 13 horizontal gerichtet. Aus dieser Stellung kann die Waffe 13 einerseits gesenkt werden, bis die Waffenrohre um ca. 10-15° abwärts geneigt sind, und andererseits lässt sich die Waffe um annähernd 90° elevieren, bis die Waffenrohre 14 annähernd in den Zenith ragen. Die abwärts geneigten Waffenrohre 14 sind mit der Bezugsziffer 14a und die in den Zenith ragenden Waffenrohre 14 sind mit der Bezugsziffer 14b bezeichnet.1, the cartridges 11 are fed from a drum magazine 10 to a firearm 13 via a delivery channel 12. The firearm 13 is shown in FIG. 1 in three different elevation positions. In the middle position, the gun barrels 14 of the firearm 13 are directed horizontally. From this position, the weapon 13 can be lowered on the one hand until the weapon barrels are inclined downward by approximately 10-15 °, and on the other hand the weapon can be raised by approximately 90 ° until the weapon barrels 14 project approximately into the zenith. The downwardly inclined weapon barrels 14 are designated by the reference number 14a and the weapon barrels 14 projecting into the zenith are designated by the reference number 14b.

Gemäss Fig. 2 befindet sich zwischen dem Förderkanal 12 und der Waffe 13 noch ein sogenannter Scheibenkanal 15, der eine Elevation der Feuerwaffe 13 um annähernd 90° gestattet. Die Patronen 11 gelangen aus dem Trommelmagazin 10 auf eine endlose Förderkette 16. Diese Förderkette 16 wird am einen Ende des Förderkanals um ein Kettenrad 17 gelenkt. Neben der Feuerwaffe 13 befindet sich ein weiteres, nicht dargestelltes Kettenrad zum Umlenken der Förderkette 16. Die Förderkette 16 wird durch den Scheibenkanal 15 hindurchgeführt. Am Eingang zum Scheibenkanal 15 sind Umlenkrollen 18 für die Förderkette 16 vorgesehen.According to FIG. 2, a so-called disk channel 15 is located between the delivery channel 12 and the weapon 13, which allows the firearm 13 to be raised by approximately 90 °. The cartridges 11 pass from the drum magazine 10 onto an endless conveyor chain 16. This conveyor chain 16 is guided around a chain wheel 17 at one end of the conveyor channel. In addition to the firearm 13 there is another sprocket (not shown) for deflecting the conveyor chain 16. The conveyor chain 16 is through the disk channel 15 passed through. Deflection rollers 18 for the conveyor chain 16 are provided at the entrance to the disk channel 15.

In Fig. 3 sind zwei, im Trommelmagazin 10 befindliche Patronenreihen 19 und 20 sichtbar. Die Patronenreihe 19 kann in der gezeigten Stellung mit Hilfe einer weiter unten beschriebenen Fördervorrichtung 27 dem Förderkanal 12 zugeführt werden. Damit die Patronenreihe 20 dem Förderkanal 12 zugeführt werden kann, muss zuerst das Trommelmagazin 10 um seine Achse 21 um 180° gedreht werden. Aus Fig. 3 ist ferner ersichtlich, dass die Feuerwaffe 13 sechs Waffenrohre 14 besitzt, die sich bei einem Seriefeuer um ihre gemeinsame Achse 22 drehen.3 shows two rows of cartridges 19 and 20 located in the drum magazine 10. The row of cartridges 19 can be fed to the conveying channel 12 in the position shown with the aid of a conveying device 27 described below. So that the cartridge row 20 can be fed to the conveying channel 12, the drum magazine 10 must first be rotated by 180 ° about its axis 21. From Fig. 3 it can also be seen that the firearm 13 has six gun barrels 14 which rotate about their common axis 22 in a series fire.

Gemäss Fig. 4 weist ein Trommelmagazin 10 dreissig Sektoren 23 auf, von denen nur die Mittellinien angedeutet sind. Jeder Sektor 23 enthält eine Reihe von fünfundzwanzig Patronen 11. In Fig. 1 ist von zwei Sektoren 23 nur jeweils die erste Patrone 11 einer Reihe dargestellt. Das Trommelmagazin 10 befindet sich in einem zylindrischen Gehäuse 24 (Fig. 5 und 6) von dem in Fig. 4 nur die vordere, scheibenförmige Stirnwand 25 sichtbar ist. Die Stirnwand 25 besitzt eine Oeffnung 26, durch welche Patronen 11 aus dem Trommelmagazin 10 entnommen werden können. Durch eine Fördervorrichtung 27, die weiter unten beschrieben ist, wird eine Patronenreihe 19, 20 nach der anderen durch die Oeffnung 13 aus dem . Trommelmagazin 10 hinausgeschoben. Während eine Patronenreihe 19 aus dem Trommelmagazin 10 hinausgeschoben wird, dreht sich das Trommelmagazin 10 kontinuierlich um eine Teilung weiter, d. h. die Stelle A des Trommelmagazins 10 gelangt an die Stelle B. Mit anderen Worten, bei der Verschiebung einer Patrone 11 in achsialer Richtung vom einen Ende zum anderen Ende des Trommelmagazins 10 erfolgt eine Drehung des Trommelmagazins 10 um eine Teilung, wodurch die Patrone 11 von der Stelle A zur Stelle B gelangt. Die aus dem Trommelmagazin 10 ausgestossenen Patronen 11 gelangen durch den Förderkanal 12, der in Fig. 4 durch zwei Wände 28, 29 angedeutet ist, zur Feuerwaffe 13. In diesem Förderkanal 12 befindet sich eine zweite Fördervorrichtung 30a, die weiter unten beschrieben ist. Die aus der Drehung des Trommelmagazins 10 - in Richtung des Pfeiles D - und der achsialen Verschiebung der Patronenreihe 19 resultierende Bewegungsrichtung der Patronen 11 stimmt mit der Förderrichtung der Fördervorrichtung 27 überein, d. h. die Achse dieser Fördervorrichtung 27 ist so geneigt, dass ihre Richtung mit dieser resultierenden Bewegungsrichtung zusammenfällt, wie aus Fig. 4 deutlich zu erkennen ist. Eine weiter unten beschriebene Rücklaufsperre vor der Oeffnung 26 verhindert, dass die durch die Fördervorrichtung 27 aus dem Trommelmagazin 10 ausgestossenen Patronen 11 wieder durch die Oeffnung 26 zurückfallen können.4, a drum magazine 10 has thirty sectors 23, of which only the center lines are indicated. Each sector 23 contains a row of twenty-five cartridges 11. In FIG. 1, of the two sectors 23, only the first cartridge 11 of a row is shown. The drum magazine 10 is located in a cylindrical housing 24 (FIGS. 5 and 6), of which only the front, disk-shaped end wall 25 is visible in FIG. 4. The end wall 25 has an opening 26 through which cartridges 11 can be removed from the drum magazine 10. By means of a conveying device 27, which is described further below, one row of cartridges 19, 20 after another is opened through the opening 13. Drum magazine 10 pushed out. While a cartridge row 19 is being pushed out of the drum magazine 10, the drum magazine 10 rotates continuously by one division, i. H. the position A of the drum magazine 10 comes to the position B. In other words, when a cartridge 11 is displaced in the axial direction from one end to the other end of the drum magazine 10, the drum magazine 10 rotates by one division, as a result of which the cartridge 11 moves from the Position A reached position B. The cartridges 11 ejected from the drum magazine 10 pass through the conveyor channel 12, which is indicated in FIG. 4 by two walls 28, 29, to the firearm 13. In this conveyor channel 12 there is a second conveyor device 30a, which is described further below. The direction of movement of the cartridges 11 resulting from the rotation of the drum magazine 10 - in the direction of arrow D - and the axial displacement of the cartridge row 19 coincides with the conveying direction of the conveyor device 27, i. H. the axis of this conveyor device 27 is inclined so that its direction coincides with this resulting direction of movement, as can be clearly seen from FIG. 4. A backstop in front of the opening 26 described below prevents the cartridges 11 ejected from the drum magazine 10 by the conveying device 27 from falling back through the opening 26.

Zum Antrieb des Trommelmagazins 10 dient ein Zahnrad 38, das an einer Stirnseite des Trommelmagazins 10 befestigt ist und von dem erwähnten Elektromotor angetrieben wird. wie weiter unten beschrieben ist.5 and 6, the conveyor device 27 has a screw conveyor 30. The screw conveyor 30 consists of a cylindrical body 31 to which a helical rib 32 is attached. The two ends of the screw conveyor 30 are held in bearings 33 (FIG. 5) and 34 (FIG. 6) in the housing 24 of the drum magazine 10. To drive the screw conveyor 30 is a gear 35, which is attached to one end of the screw conveyor 30. The gear 35 is driven by a hydraulic motor, as described below. The drum magazine 10 contains a drum axis 21. The two ends of the drum axis 21 are held in bearings 36 (FIG. 5) and 37 (FIG. 6) in the housing 24 of the drum magazine 10. A gear 38 is used to drive the drum magazine 10, which gear wheel is fastened to an end face of the drum magazine 10 and is driven by the aforementioned electric motor. as described below.

Jede Patronenreihe 19, 20 wird im Trommelmagazin 10 in einer achsial gerichteten Schiene 39 verschiebbar gehalten. Von einer solchen Patronenreihe 19 ist in Fig. 5 die erste Patrone 11 und in Fig. 6 die letzte Patrone 11 dargestellt. In der Schiene 39 ist ein Mitnehmer 40 verschiebbar, der einen Bolzen 41 besitzt. Der Bolzen 41 steht in Eingriff mit der schraubenförmigen Rippe 32 der Förderschnecke 30. Durch die Drehung der Förderschnecke 30 bewegt sich der Mitnehmer 40 aus seiner rechten Endstellung gemäss Fig. 6 in seine linke Endstellung gemäss Fig. 5 und schiebt dabei eine Reihe von fünfundzwanzig Patronen 11 aus dem Trommelmagazin 10 heraus. Im erwähnten Förderkanal 12 mit den Wänden 28 und 29 (Fig. 5) befindet sich eine endlose Förderkette 16, die aus einzelnen Kettengliedern 42 besteht, siehe auch Fig. 7. Jedes Kettenglied 42 besitzt einen T-förmigen Ansatz 43, der in einer im Querschnitt C-förmigen Schiene 44 bezw. 45 geführt ist. In der linken Schiene 44 bewegen sich die Kettenglieder 42 mit den Patronen 11 vom Trommelmagazin 10 zur Feuerwaffe 13 und in der benachbarten Schiene 45 gelangen die leeren Kettenglieder 42 von der Feuerwaffe 13 zum Trommelmagazin 10 zurück. An beiden Enden der Schienen 44 und 45 sind in Fig. 6 nicht dargestellte Umlenkrollen vorhanden, durch welche die endlose Förderkette 16 aus der einen Schiene 44, 45 in die andere Schiene 45, 44 umgelenkt wird.Each row of cartridges 19, 20 is held in the drum magazine 10 so as to be displaceable in an axially directed rail 39. The first cartridge 11 of such a cartridge row 19 is shown in FIG. 5 and the last cartridge 11 in FIG. 6. In the rail 39 a driver 40 is displaceable, which has a bolt 41. The bolt 41 is in engagement with the helical rib 32 of the screw conveyor 30. By rotating the screw conveyor 30, the driver 40 moves from its right end position according to FIG. 6 into its left end position according to FIG. 5 and thereby pushes a series of twenty-five cartridges 11 out of the drum magazine 10. In the mentioned conveyor channel 12 with the walls 28 and 29 (Fig. 5) there is an endless conveyor chain 16, which consists of individual chain links 42, see also Fig. 7. Each chain link 42 has a T-shaped extension 43, which in a Cross section of C-shaped rail 44 or 45 is performed. The chain links 42 with the cartridges 11 move from the drum magazine 10 to the firearm 13 in the left rail 44 and the empty chain links 42 return from the firearm 13 to the drum magazine 10 in the adjacent rail 45. At both ends of the rails 44 and 45 there are deflection rollers, not shown in FIG. 6, through which the endless conveyor chain 16 is deflected from one rail 44, 45 into the other rail 45, 44.

Gemäss Fig. 7 bewegt sich die endlose Förderkette 16 quer zu den Schienen 39 in Richtung des Pfeiles P und die Patronen 11 werden durch den Mitnehmer 40 in Richtung des Pfeiles F in den Schienen 39 gegen die endlose Förderkette 16 geschoben. Durch die Drehung des Trommelmagazins 10 bewegen sich ausserdem die Führungsschienen 39 in Richtung des Pfeiles E. Am Ende jeder Führungsschiene 39 ist eine Klappe 46 um eine Achse 47 schwenkbar angelenkt. Diese Klappe 46 wird durch eine nicht dargestellte Vorrichtung geöffnet und geschlossen. Die Patrone 11a der nächstfolgenden Reihe wird die Klappe 46a. die sich am Ende der vorhergehenden Reihe von Patronen 11 befindet, wieder schliessen. Dadurch wird verhindert, dass Patronen 11 in bereits entleerte Sektoren 23 hineinfallen, wenn sie sich auf der endlosen Förderkette 16 befinden.7, the endless conveyor chain 16 moves transversely to the rails 39 in the direction of arrow P and the cartridges 11 are pushed by the driver 40 in the direction of arrow F in the rails 39 against the endless conveyor chain 16. The rotation of the drum magazine 10 also causes the guide rails 39 to move in the direction of the arrow E. At the end of each guide rail 39, a flap 46 is pivoted about an axis 47. This flap 46 is opened and closed by a device, not shown. The next row of cartridges 11a becomes the flap 46a. close the end of the previous row of cartridges 11. This prevents cartridges 11 from falling into already emptied sectors 23 when they are on the endless conveyor chain 16.

Gemäss Fig. 8 ist je eine Klappe 46 an einer Achse 47 schwenkbar zu beiden Seiten der Kettenglieder 42 der endlosen Förderkette 16 angeordnet. Wie aus Fig. 7 und 8 ersichtlich ist, weist jedes Kettenglied 42 eine Schale 48 auf, die zur Aufnahme einer Patrone 11 dient. An dieser Schale 48 ist ein Träger 49 befestigt, dessen eines Ende sich gabelartig teilt. An beiden Enden des Trägers 49 sind Bohrungen 50 und 51 vorhanden. Beim zusammensetzen der Kettenglieder42 befindet sich das Ende mit der Bohrung 50 des einen Kettengliedes 42a im gegabelten Ende des benachbarten Kettengliedes 42b. Die einzelnen Kettenglieder 42 werden durch Bolzen 52 gelenkig miteinander verbunden.According to FIG. 8, a flap 46 is pivotably arranged on an axis 47 on both sides of the chain links 42 of the endless conveyor chain 16. As can be seen from FIGS. 7 and 8, each chain link 42 has a shell 48 which serves to receive a cartridge 11. A carrier 49 is fastened to this shell 48, one end of which divides like a fork. Bores 50 and 51 are provided at both ends of the carrier 49. When assembling the chain links 42, the end with the bore 50 of one chain link 42a is in the forked end of the adjacent chain link 42b. The individual chain links 42 are articulated to one another by bolts 52.

Gemäss Fig. 9 weist das obere Kettenrad 54 fünf Aussparungen 57 auf, in welche die Gelenke 58 einer endlosen Förderkette 66 eingreifen. Ein unteres Kettenrad 53 ist gemäss Fig. 9 gleich ausgebildet, wie das obere Kettenrad 54. An der endlosen Kette 66 sind Mitnehmer 59 befestigt, welche in gleichen Abständen voneinander angeordnet sind und welche die Aufgabe haben, die Patronen 11 aus den Sektoren 23 des Trommelmagazins 10 herauszuschieben. Die aus dem. Trommelmagazin 10 herausgeschobenen Patronen 11 werden einer zweiten Förderkette 60 zugeführt. Diese zweite Förderkette 60 bewegt sich in Richtung des Pfeiles B über das Trommelmagazin 10 hinweg und bringt die Patronen 11 zur Feuerwaffe 13. Die endlose Förderkette 66 bewegt sich in Richtung des Pfeiles A und das Trommelmagazin 10 dreht sich in Richtung 'des Pfeiles C (Fig. 9). Gemäss Fig. 9 befindet sich ein Schieber 61 unterhalb der zweiten Förderkette 60 und über den im Trommelmagazin 10 angeordneten Patronen 11. Dieser Schieber 61 weist eine Durchtrittsöffnung 62 und eine Umlenknase 63 auf, welche dafür sorgt, dass die Patronen 11 genau in die einzelnen Aufnahmebecher 64 der zweiten Förderkette 60 gelangen. Dieser Schieber 61 wird durch eine nicht dargestellte Nockenscheibe oder Exzenterscheibe in Richtung des Doppelpfeiles D hin und her bewegt. Sobald die letzte Patrone 11a einer Patronenreihe sich in der zweiten Förderkette 60 befindet, wird der Schieber 61 in Richtung des Pfeiles B in Fig. 9 nach links verschoben, bis sich die Durchtrittsöffnung 62 über der ersten Patrone 11 der nächsten Patronenreihe befindet. Anschliessend wird der Schieber 61 mit der gleichen Geschwindigkeit wie das Trommelmagazin 10 in Richtung des Pfeiles C in Fig. 9 nach rechts verschoben und somit befindet sich die Durchtrittsöffnung 62 des Schiebers 61 beim Ausschieben einer Patronenreihe ständig über dieser Reihe.According to FIG. 9, the upper chain wheel 54 has five recesses 57, in which the joints 58 of an endless conveyor chain 66 engage. A lower sprocket 53 is designed according to FIG. 9 in the same way as the upper sprocket 54. On the endless chain 66, drivers 59 are fastened, which are arranged at equal distances from one another and which have the task of removing the cartridges 11 from the sectors 23 of the drum magazine 10 push out. The one from the. Drum magazine 10 pushed cartridges 11 are fed to a second conveyor chain 60. This second conveyor chain 60 moves in the direction of arrow B over the drum magazine 10 and brings the cartridges 11 to the firearm 13. The endless conveyor chain 66 moves in the direction of arrow A and the drum magazine 10 rotates in the direction of the arrow C (FIG . 9). According to FIG. 9, a slide 61 is located below the second conveyor chain 60 and above the cartridges 11 arranged in the drum magazine 10. This slide 61 has a passage opening 62 and a deflection nose 63, which ensures that the cartridges 11 fit exactly into the individual receiving cups 64 of the second conveyor chain 60. This slide 61 is moved back and forth in the direction of the double arrow D by a cam disk or eccentric disk, not shown. As soon as the last cartridge 11a of a row of cartridges is located in the second conveyor chain 60, the slide 61 is shifted to the left in the direction of arrow B in FIG. 9 until the passage opening 62 is located above the first cartridge 11 of the next row of cartridges. Subsequently, the slide 61 is displaced to the right at the same speed as the drum magazine 10 in the direction of arrow C in FIG. 9, and the passage opening 62 of the slide 61 is thus constantly above this row when a row of cartridges is pushed out.

Wie aus Fig. 9 ersichtlich ist, wandert auch der Mitnehmer 59 während er eine Patronenreihe aus dem Trommelmagazin 10 herausschiebt, d. h. während er aus seiner unteren Stellung 59a in seine obere Stellung 59b gelangt, dank der Schrägstellung der Förderkette 66 in Richtung des Pfeiles C nach rechts in Fig. 9. Die Neigung der endlosen Förderkette 66 gegenüber einer Vertikalen ist dabei so gewählt, dass sich auch der Mitnehmer 59 mit der selben Geschwindigkeit in Richtung des Pfeiles C bewegt, wie das Trommelmagazin 10. Somit bleibt der Mitnehmer 59 bei seiner Aufwärtsbewegung ständig in Eingriff mit der untersten Patrone 11c einer Reihe in einem Sektor 23.As can be seen from Fig. 9, the driver 59 also migrates while pushing a row of cartridges out of the drum magazine 10, i. H. while it moves from its lower position 59a to its upper position 59b, thanks to the inclined position of the conveyor chain 66 in the direction of the arrow C to the right in FIG. 9. The inclination of the endless conveyor chain 66 with respect to a vertical is chosen such that the Driver 59 moves in the direction of arrow C at the same speed as drum magazine 10. Thus, driver 59, as it moves upward, remains constantly engaged with the bottom cartridge 11c of a row in sector 23.

Der Mitnehmer 59 ist so geformt, dass er die letzte Patrone 11 einer Reihe solange berührt, bis sie vollständig in einem Aufnahmebecher 64 der zweiten Förderkette 60 eingeschoben ist. Dadurch wird jeder freie Flug eine Patrone 11 beim Eintritt in die Förderkette 60 vermieden.The driver 59 is shaped in such a way that it touches the last cartridge 11 in a row until it is completely inserted into a receiving cup 64 of the second conveyor chain 60. As a result, each free flight of a cartridge 11 is avoided when entering the conveyor chain 60.

Bei den Ausführungsbeispielen gemäss Fig. 10 ist der Schieber 61 (Fig. 9) durch schwenkbare Klappen 65 ersetzt. Diese Klappen 65 sind an Zwischenwänden 76 des Trommelmagazins 10 angelenkt, werden durch eine nicht dargestellte Vorrichtung geöffnet und geschlossen. Gemäss Fig. 10 bewegt sich diese Förderkette 60 in Richtung des Pfeiles B nach links. Entsprechend werden die Klappen 65 gemäss Fig. 10 durch die Patronen 11 im Gegenuhrzeigersinn geöffnet.In the exemplary embodiments according to FIG. 10, the slide 61 (FIG. 9) is replaced by pivotable flaps 65. These flaps 65 are hinged to partition walls 76 of the drum magazine 10, are opened and closed by a device, not shown. 10, this conveyor chain 60 moves in the direction of arrow B to the left. Accordingly, the flaps 65 according to FIG. 10 are opened by the cartridges 11 in the counterclockwise direction.

Gemäss Fig. 11 dient zum Antrieb des Trommelmagazins 10 ein Hydromotor 67, der es über Zahnräder 68 und 69, ein Reduktionsgetriebe 70 und die Zahnräder 71 und 38 (Fig. 6) antreibt. Ferner wird durch den Motor 67 über eine Kupplung 72 und die Zahnräder 73 und 35 (Fig. 6) die Förderschnecke 30 der ersten Fördervorrichtung 27 angetrieben. Ueber ein weiteres, an der Förderschnecke 30 befestigtes Zahnrad 74, wird in nicht dargestellter Weise die zweite Fördervorrichtung 30a (Fig. 2) angetrieben. Das Uebersetzungsverhältnis des in Fig. 11 dargestellten Zahnradgetriebes muss selbstverständlich so gewählt werden, dass bei einer Umdrehung des Trommelmagazins sämtliche Patronenreihen 19,20 durch die Fördervorrichtung 27 ausgestossen werden.11, a hydraulic motor 67 is used to drive the drum magazine 10, which drives it via gearwheels 68 and 69, a reduction gear 70 and the gearwheels 71 and 38 (FIG. 6). Furthermore, the conveyor screw 30 of the first conveyor device 27 is driven by the motor 67 via a clutch 72 and the gear wheels 73 and 35 (FIG. 6). The second conveyor device 30a (FIG. 2) is driven in a manner not shown via a further gearwheel 74 attached to the screw conveyor 30. The gear ratio of the gear transmission shown in FIG. 11 must of course be selected such that all cartridge rows 19, 20 are ejected by the conveying device 27 when the drum magazine is rotated.

Gemäss Fig. 12 besteht die Förderschnecke 30 aus einem zylindrischen Körper 31, an dem eine schraubenförmige Rippe 32 befestigt ist, siehe auch Fig. 5 und 6. Diese Rippe 32 weist an ihrem rechten Ende für die erste Windung eine kleinere Steigung auf, damit die aus dem Stillstand zu beschleunigende Patronenreihe sanft beschleunigt werden kann, ohne dass grosse Beschleunigungskräfte auftreten.12, the screw conveyor 30 consists of a cylindrical body 31 to which a helical rib 32 is fastened, see also FIGS. 5 and 6. This rib 32 has a smaller pitch at its right end for the first turn, so that the Cartridge row to be accelerated from standstill can be gently accelerated without large acceleration forces occurring.
