Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an ammunition storage device installed in a vehicle-mounted turret gun, and more particularly to an ammunition magazine that stores bullets and charges in a selectively removable manner. Regarding.

(Prior Art) Conventionally, in turret guns such as vehicle-mounted grenade guns, there has been a tendency to use separate ammunition, which is separated into a bullet and a charge, as the guns become larger. This separated ammunition is stored in the rear of the turret, with the bullet and charge separated, and the bullet is drum-shaped,
It is stored in a rack type, endless chain type, etc. bullet magazine, and the charge is stored in a charging case.

(Intelligence M to be Solved by the Invention) However, according to the above method of storing ammunition, there is a problem that the storage efficiency is low and it is difficult to increase the number of ready-to-react ammunition.

That is, a bullet magazine stores bullets so that they can be taken out by mechanical force, and because the bullet conveyance mechanism, support mechanism, etc. occupy a relatively large area, a sufficient space for storing bullets cannot be secured. In addition, the cartridge case is stored so that it can be taken out manually, and it is placed inside the turret using the remaining space where the bullet magazine is placed, so it can store the same number of bullets as the bullet magazine. I can't. −
On the other hand, in order to store the same number of charges as bullets, it is necessary to increase the number of bullet magazines due to space constraints within the turret, which further reduces the number of bullets that can be stored. Therefore, it is difficult to maintain the same number of bullets and charges while increasing the number of ready-to-respond ammunition.

Incidentally, in a turret gun, in order to improve the firing performance, it is required that ammunition be transferred by mechanical force.

Regarding bullets, various bullet transfer mechanisms that use mechanical force have already been proposed, and it has been proposed to combine these bullet transfer mechanisms with each of the above-mentioned bullet magazines to transfer bullets from the storage location to the gun using mechanical force. . On the other hand, charging is done manually, but as the firing range required for guns increases, they become larger and heavier, making it difficult to transfer them manually to the guns. Because of this, various types of charge transfer mechanisms that use mechanical force to transfer the charge have been studied. Therefore, there is a demand for a charge magazine that can be used in combination with a charge transfer mechanism for storing charges.

In addition, in order to ensure firing performance commensurate with the firing range, guns are required to have an ammunition storage device that can carry and selectively take out a variety of types of ammunition.

In particular, with regard to charges, in addition to integrated charges such as cartridge-type charges, split-type charges in which one charge is divided into multiple parts have been proposed; Since it is necessary to select and combine the necessary number of charges 9 to form a charge 9 corresponding to the firing range, it is required to store the charges so that they can be assembled and taken out.

The present invention has been made in view of the above-mentioned conventional situation, and an object of the present invention is to provide an ammunition magazine that has high storage efficiency and can increase the number of ready-to-read ammunition. Another object of the present invention is to provide an ammunition magazine from which ammunition can be selectively taken out depending on the firing range.

Thereafter, bullets or charges are carried into all the tubes 8.23 in the same manner, and the respective bullet types or charges are stored.

When carrying out ammunition, the bullet type or charge amount stored in the bullet type storage means or charge amount storage means is read, and each tube 8゜23 storing a predetermined bullet or charge is connected to each discharge port 11.
．． 26 are selected, and these are installed at each exit 1.
Each index sprocket 9.24 is driven to move the shortest distance to 1.26. This positions a given bullet or charge at each output 011.26. Thereafter, each output 64412.27 is activated and the bullet or charge is simultaneously discharged from the six output ports 11,26.

Next, when transporting ammunition when using split-type charges, the bullets are carried in the same way as described above, but for the charge, one of the charge tubes 23, for example, the first or last charge tube 23, is loaded. The same amount of charge is carried in, and the empty charge tube 23 is positioned at the charge discharge port 26 when the carry-in is completed. And when transporting ammunition,
The bullet is carried out in the same manner as described above, but only a predetermined number of the charge tube pieces 23a from the rear are moved by the charge indexing sprocket 24 in the l-pitch horizontal axis direction so that a predetermined amount of charge is obtained. and positioned at the charge outlet 26. Thereby, automatic condensation of the charge is performed, and a predetermined amount of charge can be selected and taken out, and unused charges can be reused to prevent waste.

(Effects of the Invention) According to the present invention, each housing of the bullet magazine and the charge magazine has a guide passage formed in a horizontally flat O-shape, and the bullet or charge is stored in the guide passage. Since the tubes are mounted so as to be circumscribed and movable in the transverse direction, the number of each tube to be mounted is set according to the length of each guide passage in the transverse direction. Therefore, by appropriately setting the length of each of the guide passages, the number of tubes installed in both magazines can be equalized and increased, making it possible to increase the number of ready-to-read ammunition.

Since the bullet and charge are stored in a tube, and this tube is moved in the horizontal axis direction by an indexing sprocket, various items can be stored regardless of shape, size, etc. Therefore, it is possible to store a mixture of various bullets and charges, and select ammunition according to the firing range.
It became possible to improve the firing performance. Regarding the charge magazine, if the tube is made up of charge tube segments equally divided in the longitudinal direction and the indexing sprocket selectively drives each charge tube segment, it is possible to The indexing sprocket of can be driven to position a predetermined number of charge tube pieces at the outlet, so split-type charges can be used, and the necessary charge can be selected and taken out! can be done easily.

Since the bullet magazine and the charge magazine are stacked vertically, it can be used in combination with an ammunition transfer device having a bullet tray and a charge tray arranged vertically. Ammunition could be transferred from the storage location to the gun in a short time, allowing for high-speed firing.
