Definitions
- the invention relates to a method and a device for supplying ammunition to revolver cannons, with cartridges transported with a conveyor chain to one coaxially a revolver drum arranged star wheel.
- 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 attached to the drum and the second conveying member transfers the cartridges to it.
- the device described above has a relatively complicated structure and has no devices for the removal of the empty cartridge cases, as is advantageous, for example, in the case of revolver guns used for aircraft.
- the invention has for its object a method and a device of the event to propose the type mentioned which do not have the disadvantages mentioned above and are particularly suitable for aircraft.
- the cartridges are loaded shortly before reaching the Revolver cannon in a first path that deviates from the conveying direction of the conveyor chain steered and guided at a greater distance from the revolver drum around its axis and transported further.
- the cartridges are in a shooting phase shortly before reaching the Revolver cannon in a second, which deviates from the conveying direction of the conveyor chain Track steered, guided around the axis of the revolver drum and immediately behind it brought into a firing position one after the other
- the empty cartridge cases are moved caught shooting and throwing and on the first lane in a magazine transported.
- the advantages achieved with the invention are as follows:
- the proposed device with return of the empty cartridge cases and misfired cartridges enables automatic loading and unloading of the cannon and is particularly suitable for airplanes (unloading the cannon before landing) and wherever unmanned work has to be carried out (difficult access to the cannon).
- the continuous movement of the main parts of the conveyor system reduces loads and optimizes energy consumption.
- Fig. 1 denotes a revolver cannon to which a feed device 2 is attached.
- the feed device 2 is connected to one end of a conveyor 3 , the other end of which is attached to a magazine 4 .
- the feed device 2 supplies a revolver drum ( 13 , FIG. 3 ) of the revolver cannon 1 with cartridges 5, catches the ejected empty cartridge cases 6 again and transfers them to the conveyor 3 .
- the conveyor 3 removes the cartridges 5 from the magazine 4 , transports them to the revolver cannon 1 and conveys the empty cartridge cases 6 back to the magazine 4 .
- the feed device 2 consists essentially of a housing 7 , a clutch 8 , a star wheel 9 , two transfer wheels 10 , a displacement device 11 for an adjustable guide 12 of the conveyor 3 and an ejector tube and safety device for not shown the empty cartridge cases 6 .
- the star wheel 9 is in two parts, consisting of a front part which is coupled to the turret drum 13 and a rear part which can be uncoupled from the front part or from the turret drum 13 .
- the rear part is uncoupled from the revolver drum 13 , and cartridges 5 can be transported in the rear part about the revolver drum axis.
- the first cartridge from the conveyor 3 is positioned behind the last one in the front star wheel part.
- the star wheel 9 arranged coaxially to the turret drum 13 can be coupled or uncoupled therefrom.
- the star wheel 9 holds the cartridges 5 during the loading of the revolver drum 13 and also drives a conveyor chain 14 of the conveyor 3 via a gear.
- the catching device stops the ejected cartridge cases 6 or cartridges 5 and transfers them to the conveyor chain 14 of the conveyor 3 , the cartridge cases 6 or cartridges 5 being guided by a fixed guide 16 and the adjustable guide 12 of the feed device 2 or the conveyor 3 .
- the cartridges 5 can be steered into another path by means of the displacement device 11 or the adjustable guide 12 , so that they cannot be pushed back into an axis 15 of the revolver drum 13 when it rotates around it.
- the conveyor 3 consists of a housing 17, the conveyor chain 14, the adjustable and fixed guide 12 or 16 , two star wheels 18, 19 and two transfer wheels 20.
- the housing 17 has two side walls 17.1, 17.2 , which, starting from the magazine 4 , are arranged at an acute angle to the conveying direction of the conveyor chain 14 and reach their greatest distance from one another on the feed device 2 .
- the fixed guide 16 is arranged in the region of the upper run 14.1 of the conveyor chain 14 running parallel to the one side wall 17.1 .
- the adjustable guide 12 is arranged in the region of the lower run 14.2 of the conveyor chain 14 , running parallel to the one side wall 17.1 in a first position and parallel to the other side wall 17.2 in a second position.
- the conveyor chain 14 is guided around the star wheels 18 , 19 arranged at both ends of the housing 17 , one star wheel 18 being able to be driven by the feed device 2 and the other star wheel 19 being driven by the magazine 4 .
- the conveyor chain 14 transports the cartridges 5 from the magazine 4 to the feed device 2 and the empty cartridge cases 6 from the latter back to the magazine 4 , the transfer wheels 20 transporting from and to the star wheel 19 or a conveyor chain 22 of the magazine 4 to the conveyor chain 14 of the conveyor 3 and back support.
- the magazine 4 has a housing consisting essentially of two plates 23 connected by means of spacer columns and a cover. Bearings for shafts 24 and guide grooves for the conveyor chain 22 are provided in the plates 23 .
- the conveyor chain 22 consists of two endless roller chains to which cup-shaped holders adapted to the cartridges 5 and the cartridge cases 6 are fastened. Guides for the cartridges 5 or cup-shaped holders are arranged on the spacer columns.
- the chain links of the roller chains are coupled to one another with play, so that the distance between two chain links can widen or shorten, a buffer effect being achieved and some cartridges 5 being able to be stored.
- the conveyor chain 22 is guided around the shafts 24 , some of which are driven on the outside of one of the plates 23 via pinions.
- One of the shafts 24 is designed such that it can be turned by hand from the outside.
- a servo motor 25 which is also attached to the outside of one of the plates 23 , serves to drive the conveyor chain 22 .
- the housing of the magazine 4 has a door with a loading ramp for loading cartridges 5 and unloading empty cartridge cases 6 .
- the adjustable guide 12 is pushed into the first position by means of the displacement device 11, in which position it coincides with the fixed guide 16 .
- the cartridges 5 are transported via the transfer wheels 10 and the star wheel 9 from the lower run 14.2 around the axis 15 past a device for inserting the cartridges 5 into the revolver drum 13 .
- the rear part of the star wheel 9 is uncoupled from the turret drum 13 and the servo motor 25 drives the conveyor chains 14, 22 until the cartridges 5 entered into the opening of the magazine 4 and captured by the cup-shaped holders of the conveyor chain 22 have the maximum number to be filled Have reached number.
- the adjustable guide 12 When firing (FIG. 5 ), the adjustable guide 12 is switched into the second position by means of the displacement device 11 , so that the cartridges 5 are transported from the lower run 14.2 of the conveyor chain 14 directly in front of the revolver drum 13 and the device for inserting the cartridges 5 takes effect. Since in this phase the turret drum 13 - the turret drum 13 is known to be driven by the back and forth slider.
- This slide drives the revolver drum 13 via an integrated control cam and, via integrated cams, it moves the cartridges 5 axially into the cartridge chamber of the revolver drum 13 .
- the slide When shooting, the slide is accelerated backwards with the shot gases via a gas piston, whereby two springs are preloaded, which bring the slide forward again.
- the slider Since there are no shot gases when loading the cannon (3 cartridges), the slider is hydraulically, pneumatically or pyrotechnically driven by a special drive piston - coupled to the rear part of the star wheel 9 and thus to the conveyor chain 14 , the rotation of the Revolver drum 13 each brought the next cartridge 5 into the firing position. Because of the buffering effect of the conveyor chain 22 of the magazine 4 , the revolver drum 13 only has to draw a few cartridges 5 . During the same time, the servo motor 25 is switched on in order to restore the buffering effect of the conveyor chain 22 . The empty cartridge cases 6 ejected after the shot are caught by the catching device, transferred to the upper run 14.1 of the conveyor chain 14 and guided back along the fixed guide 16 .
- the workflow of the device is monitored by sensors and controlled by a central control device.
- the sensors of the feed device 2 provide, for example, information about the position of the star wheel 9 , the position of the adjustable guide, position of the clutch 12 and the presence of a cartridge 5 in a feed position on the revolver drum 13 .
- the sensors of the magazine 4 provide information about the servo motor 25 and the position of the loading door as well as the correct loading function.
