Description

Detailed Description of the Invention (a) Industrial Application Field The present invention provides a projectile launcher with a projectile and a charge (
(hereinafter referred to as "ammunition" unless there is a particular need to distinguish)
This relates to an ammunition supply device that supplies ammunition. A charge (also called a propellant cartridge) is placed at the rear end of a flying object in a flying vehicle launcher in order to give the flying object (also called a projectile or a cannonball) the energy to launch it, and is ignited to cause deflagration. It is something to do.

(b) Conventional technology When supplying flying bodies and charges to large-caliber cannons, in order to handle the heavy flying bodies and charges, the flying bodies and charges are separated into breech openings. transported to the department,
It is loaded inside the gun barrel. An example of such an ammunition feeding device is the one shown in Japanese Patent Publication No. 63-34397. The projectile and propellant cartridges are stored in separate drum-like storage barrels located on either side of the breech. Support and transfer plates for the ammunition feeder are also located on both sides of the breech, with a receiving position for receiving projectiles or propellant cartridges from both storage barrels, and a longitudinal axis of the breech opening (also known as the gun axis). ) is configured to swing between the top loading position and In other words, the projectile support and transfer device is, for example, swung counterclockwise from the receiving position to the loading position, and the propellant cartridge support and transfer device (operation timing is shifted from that of the projectile support and transfer device). ) From the receiving position, it is swung clockwise, for example, to the loading position. A loading device is located in the loading position for receiving the projectile or propellant cartridge from the support transfer plate and loading it into the gun barrel.

The projectile is transferred from the projectile storage barrel to the projectile support transfer device waiting at the receiving position, and the zero-order projectile is transported to the loading position on the longitudinal axis of the breech opening. It is loaded into the gun barrel by a loading device. Similarly, the propellant cartridge is
The propellant cartridge is transferred from the propellant cartridge storage to the propellant cartridge support and transfer device waiting at the receiving position, and transported to the loading position on the longitudinal axis of the breech opening. The propellant cartridge is then loaded into the muzzle by a loading device. That is, the projectile is first transported and loaded, followed by the propellant cartridge. After loading the propellant cartridge, the breech opening is closed and the propellant cartridge in the gun barrel is ignited and deflagrated, allowing the projectile in the gun barrel to be fired from the muzzle.

(c) Problems to be solved by the invention However, in the conventional ammunition feeding device as described above,
A projectile storage barrel and a projectile support transfer device are arranged on one side of the rear part of the gun barrel, and a propellant cartridge storage is arranged on the other side,
Since the propellant cartridge support and transfer device is arranged,
Both sides of the gun breech would be blocked by the storage barrel and support transfer plate, which would not only increase the size of the device (
It is an object of the present invention to solve such problems, which are inconvenient when inspecting and maintaining a flying vehicle launcher.

(d) Means for Solving the Problems The present invention provides a flying object launcher with a rotatable ladle, a flying object holding/releasing mechanism and a charge holding/releasing mechanism in the cradle, The flying object and charge held in the flying object holding/releasing mechanism and the charge holding/releasing mechanism are moved from the standby position to the delivery position and sequentially delivered to the loading machine, and the loading machine moves the flying object and charge to the flying object receiving position. The above problem is solved by configuring the device to move between the charge receiving position and the loading position, and between the charge receiving position and the loading position. That is, the ammunition feeding device of the present invention is intended for loading a flying object (30) and a charge (38) into a gun barrel (16) of a flying object launcher (10) in sequence. A cradle (22) rotatably supported by the body launcher (10), a hydraulic cylinder (62) capable of rotating the cradle (22), and the cradle (2).

0) and a delivery position where the charges (38) are sequentially released.
The flying pot receiving position receives the flying object (30) released from the releasing mechanism (24, 26, 28), and the loading position released from the charging holding/releasing mechanism (32, 34, 36) at the delivery position. The charge receiving position receives the medicine (52), and the received flying object (30) or charge (38) is placed in the gun barrel (1).
6) It is movable between the loading position and the loading position. Note that the symbols in parentheses indicate corresponding members in the embodiment.

(e) The working cradle moves from the standby position to the delivery position while holding the flying object by the flying object holding/releasing mechanism and while holding the charge by the charge holding/releasing mechanism. The loading machine is located at the flying pot receiving position and receives the flying object released from the flying object holding/releasing mechanism at the delivery position. Next, the loading machine moves from the flying shell receiving position to the loading position and loads the projectile into the gun barrel through the breech opening. Next, the loading machine moves from the loading position to the charge receiving position and receives the released charge from the charge holding/releasing mechanism at the delivery position. The cradle then returns from the delivery position to the standby position to receive the next round, while
The loading machine moves from the charge receiving position to the loading position,
The charge is loaded into the gun barrel through the breech opening. The gun is ready to fire when the breech opening is closed. The charge is ignited, causing it to deflagrate and launch the projectile. By repeating the above operations, projectiles can be fired continuously.
