Abstract

PURPOSE:To prevent some disadvantages such as a changing of direction of a bullet and a hooking of the bullet at an inlet port or the like during a period departing from an extreme end of a transporting pan to reaching the inlet port of a cannon by a method wherein a tray device for the loaded bullet supplying device for receiving the loaded bullet is comprised of a fixing member and a movable member which can be moved between a storing position in the fixing member and a loading position spaced apart by a predetermined distance from the fixing member. CONSTITUTION:A sprocket 44 is rotated through a gear mechanism 46 under a rotation of a motor 38, a chain 40 engaged with the sprocket 44 is moved, a loading head 42 fixed at an extreme end of the chain 40 causes a loaded bullet 52 on a fixing member 24 to advance forwardly toward a bullet chamber 4. The loading head 42 continues to push the bullet 52 up to a predetermined position in the bullet chamber 4. With such an arrangement, the loaded bullet 52 is positively pushed into the bullet chamber 4. Then, the motor 38 is rotated in a reverse direction and then a retracting movement of the loading head 42 and a movement of the movable member 26 toward its storing position are started.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a charge supply device for an air vehicle launcher. A charge (also called a propellant cartridge) is placed at the rear end of a projectile in a projectile launcher in order to give the projectile energy for launch, and deflagrates when ignited. be.

(B) Conventional Technology An example of an ammunition supply device for supplying projectiles and propellant cartridges to cannons is the one shown in Japanese Patent Publication No. 34397/1983. The projectile and propellant cartridge are loaded into the gun barrel from the breech at the rear of the gun barrel by an ammunition feeder.

In large-caliber cannons, the projectile and the propellant cartridge, which provides the energy for firing the projectile, are loaded separately into the barrel.

That is, the projectile is loaded first, followed by the propellant cartridge. The projectile and propellant cartridge are stored in a storage barrel, and the projectile and propellant cartridge removed from the storage barrel are delivered to a cylindrical transfer tray. The transfer tray has a groove-like track provided in the longitudinal direction at the bottom thereof, a pusher claw fitted into the track, and a pusher chain for moving the pusher claw. The breech is equipped with a chain link that opens and closes the opening of the gun barrel, and the transfer plate extends to a position where it does not interfere with the opening and closing of the chain link. That is, the end of the transfer plate on the breech side is placed a predetermined distance away from the opening of the gun barrel. During loading, with the chain open, the pusher chain is driven to hook the rear end of the projectile or propellant cartridge onto the pusher claw and move it toward the opening of the gun barrel. The push-in pawl moves the projectile or propellant cartridge to the breech end of the transfer plate and stops there. That is, the projectile or propellant cartridge that leaves the transfer plate is thrown into the gun barrel by inertial force. After loading the propellant cartridge, the projectile inside the gun barrel can be fired by closing the chain link and igniting and deflagrating the propellant cartridge inside the gun barrel. The propellant cartridge is stored in a flammable cartridge, and the amount of propellant in the cartridge is prepared in advance at a ratio of, for example, 1, 2.34, etc. depending on the distance to the target, and it can be used as needed. I am selective about using it. This allows the cannon to have a wider firing range. Note that the firing range of a cannon can also be changed by changing the cannon's elevation angle without changing the amount of propellant cartridge, but the range of range change obtained by doing this is small, and normally the propulsion The desired firing range is obtained by appropriately selecting the amount of the cartridge and the elevation angle of the cannon.

(c) Problems to be Solved by the Invention However, when using the conventional cartridge-type propellant package as described above, for example, if a target with a dose of 1 is used up against a target with a short firing range, a dose of 2 , 3, and 4 remain, they cannot be used against targets with short ranges, so their fighting power will not be fully demonstrated. In such a case, for example, removing half of the gunpowder from a cartridge with a charge of 2 and replacing it with a cartridge with a charge of 1 is not practical because it would not be done in time for an emergency. Therefore, it is conceivable to divide the propellant cartridge into small cylindrical modular charges, connect the required number of modular charges according to the firing range, and supply them to the projectile launcher. As a result, the length of each modular charge is considerably shorter than that of a conventional cartridge-type propellant, making it difficult to use conventional ammunition feeding devices as is. It is. This is because, as mentioned above, there is no member such as the guide plate that reliably guides the charge between the time the charge leaves the transfer plate and the time it reaches the entrance of the gun barrel. Between leaving the tip and reaching the entrance to the gun barrel, the charge is likely to change direction and cause problems such as getting caught at the entrance. The present invention aims to solve these problems.

(d) Means for Solving the Problems The present invention provides a tray device of a charge supply device that receives a charge between an identification member, a storage position within a fixed member, and a loading position a predetermined distance away from the fixed member. The above-mentioned problem is solved by comprising a movable member that is movable, and a loading mechanism that can be guided and loaded into a chamber containing a charge. That is, the charge supply device (10) of the present invention is arranged at the rear of the chamber (4) into which the charge (52) of the projectile launcher (40) is loaded, and is configured to prevent the movement of the charge (52). A guiding tray device (20) and a tray device (2o)

) holds the charge (52) between the fixed member (24) and the movable member (
26) to be guided and loaded into the chamber (4). Note that the symbols in parentheses indicate corresponding members in the embodiment.

(E) The required number of charges is delivered to the fixing member of the charge supply device according to the distance to the action target. After the chamber is opened and the projectile is loaded into the gun barrel, the movable member located in the retracted position within the fixed member is pulled out from the retracted position by the movable member drive device, and the tip end is inserted into the chamber entrance. It will stop when it is extended to the loading position. When the loading mechanism operates, the charge passes through the fixed member and the movable member and is loaded into a predetermined position within the chamber. When loading of the charge is completed, the movable member is driven by the movable member drive device and returns from the loading position to the storage position. The weapon is ready to fire when the chamber is closed. The charge is ignited, causing it to deflagrate and launch the projectile. By repeating the above operations, it becomes possible to continuously launch flying objects.

It can be installed in Further, after receiving the charge 52 at the retracted position, the charge supply device 10 can load the charge 52 into the chamber 4 by rotating to the operating position. The loading of the projectile 50 and the loading of the charge 52 are performed at different timings. As shown in FIGS. 3 and 4, the charge supplying device 10 receives the charge 52 into the chamber 4.

It has a loading mechanism 22 that can load the upper charge 52 into the chamber 4, and a movable member drive device 28 that can drive a movable member 26, which will be described later. In addition,
As shown in FIG. 1, a semi-cylindrical tray shutter 21 is provided at the top of the tray device 20. As shown in FIG. The tray shutter 21 is combined with the tray device 20 to form a cylindrical space, and the charge 52 can be accommodated in this space.

The tray shutter 21 is rotatable relative to the tray device 20 between an open position and a closed position. As shown in Figure 5,
The tray device 20 includes a semi-cylindrical fixed member 24 that receives the charge 52 and a semi-cylindrical movable member 26 that is fitted into a hollow portion of the fixed member 24. In FIG. 5, a through groove 25 is provided in the lower part of the fixing member 24 in the longitudinal direction. A rack 30 is provided on the bottom back surface of the movable member 26 in the longitudinal direction. The rack 30 is disposed within the through groove 25 and is engaged with a pinion 32 of the movable member drive 28. The pinion 32 is connected to the clutch 34. It is connected to a motor 38 of the loading mechanism 22 via a gear mechanism 36 and the like. Rack 30. pinion 32
．． Clutch 34° gear mechanism 36. A movable member driving device 28 is configured by a motor 38 and the like. Motor 38 is attached to fixed member 24 . By driving the movable member drive device 28 with the clutch 34 engaged, the movable member 26 can be moved in the left-right direction in FIG. 4. By doing so, the movable member 26 is movable between a stored position superimposed within the fixed member 24 and a loading position extended into the illustrated chamber 4. The loading mechanism 22 includes a chain 40. Loading head 42 attached to the end of chain 40. Sprocket 44° gear mechanism 46. It is composed of a motor 38 and the like. That is, the motor 38 also serves as a drive source for the loading mechanism 22 and the movable member drive device 28.

The sprocket 44 is rotatably supported by the fixed member 24. By driving the motor 38 and moving the loading head 42, it is possible to load the charge 52 on the fixed member 24 into the chamber 4 via the movable member 26. In addition, there is a claw-like charge fall prevention mechanism 5 at the top of the chamber 4 in Figure 1.
4 are provided. The charge fall prevention mechanism 54 is a chain link 8
When in the open position, it can rotate between the retracted position shown in FIG. 1 and the operating position shown in FIG. It is possible to press with the tip of the nail. By doing so, it is possible to prevent the charge 52 from being removed from the chamber 4. A control device 18 that controls each of the mechanisms and devices described above is provided adjacent to the charge storage section 14.

Next, the operation of this embodiment will be explained. Distance data to the target is input to the control device 18, and the control device 18 instructs the number of charges 52 to be loaded into the charge storage section 14. Both the charge supply device 10 and the flying object supply device 12 are in the retracted position shown in FIG. 2, and the tray shutter 21 of the charge supply device 10 is opened. Projectiles 50 and 1 2 receive a predetermined number of charges 52 from the projectile storage drum 16 and charge storage 14, respectively. The tray shack 21 is closed. With the chain link 8 in the open position shown in FIG. Ru. Next, flying body supply device 1
2 is rotated to the retracted position. The charge supply device 10 is then rotated to the operating position and the movable member drive device 28 is driven. That is, the clutch 34 is engaged, the motor 38 is rotated, the pinion 32 is rotated via the gear mechanism 36, and the rack 30 is moved to the left in FIG.

As a result, the movable member 26 extends from the storage position within the fixed member 24 and is located in the loading position shown in FIG. On the other hand, the rotation of the motor 38 rotates the sprocket 44 via the gear mechanism 46, the chain 40 meshing with the sprocket 44 moves, and the loading head 42 attached to the tip of the chain 40 loads the charge on the fixed member 24. 52 is moved forward toward the chamber 4. The loading head 42 continues to push the charge 52 to a predetermined position within the chamber 4 .

By doing so, the charge 52 is reliably pushed into the chamber 4. Next, the motor 38 rotates in the opposite direction to begin retracting the loading head 42 and moving the movable member 26 to the storage position. At the same time, the charge fall prevention mechanism 54 operates to prevent the charge 52 from being removed from the chamber 4.

The charge fall prevention mechanism 54 operates particularly effectively when the gun barrel 2 is in the elevation position. The loading head 42 returns to its initial position and the movable member 26 returns to its retracted position. When the chain link 8 begins to move to the closed position, the charge fall prevention mechanism 54 returns to the initial position, and the chain link 8 closes the chamber 4. This prepares it for launch. By igniting the charge 52 and deflagrating it, the projectile 50 can be launched. A series of these sequence controls is performed by the control device 18.

It should be noted that although the above description has been made using a modular charge 52, it is clear that the charge supply device of the present invention can also be used with conventional cartridge-type charges.

Further, the above description automatically transfers the charge 52 to the tray device 20.
Although it is assumed that the device is delivered to the fixing member 24, this may be delivered manually.

(G) As described in detail, according to the present invention, the required number of charges can be loaded into the chamber depending on the distance to the target, and the charges can be used effectively. . During loading, the charge is reliably guided and loaded to a predetermined position within the chamber, so there is no problem such as the charge getting caught at the entrance of the chamber.
