[0005]

The external drum device of the bullet feeding device is rotated (raised) integrally with the gun. On the other hand, the internal drum device (containing a large number of ammunition) in the external drum device is rotated independently of the lifting motion of the gun, so that the arbitrarily selected ammunition is the ammunition of the external drum device. Aligned to face the delivery section. The internal drum device is then rotated so that it is synchronized with the elevation of the gun. This keeps the selected ammunition facing the ammunition delivery section, even when the gun is on its back. In this state, the ammunition is delivered from the ammunition delivery section of the ammunition supply device toward the ammunition carrier device. The ammunition carrier receives the ammunition, conveys it to a predetermined position, and delivers it to the loading device on the gun side. Since the ammunition can be transferred from the ammunition supply device to the loading device independently of the turning motion of the gun,
It is not necessary to use a bullet feeding guide device which requires a large operation space in accordance with the lie, and the device can be made small. If the ammunition supply device is arranged adjacent to the ammunition supply device, ammunition can be replenished to the empty space after the ammunition supply of the ammunition supply device.

The ammunition supply device (re-supplying device) 86 is configured by the above. With the empty chamber 51 of the ammunition supply device 18 positioned at the predetermined replenishment position, the ammunition push-out device 108 replenishes the six ammunition 90 located at the bottom of the case 86a from the replenishment port 86b. It can be extruded into the chamber 51 of the device 18. That is, the ammunition 90 can be replenished from the ammunition supply device 86 to the ammunition supply device 18.

Next, the operation of this embodiment will be described. When the barrel 10 is swung and lifted toward the target, the external drum device 20 of the bullet feed device 18 rotates integrally with the breech device 74 by an angle corresponding to the elevation angle of the barrel 10. The internal drum device 22 of the bullet feeding device 18 is the internal drum drive device 48.
Also, by being driven via the pinion 46, the external drum device 20 can be rotated independently. As a result, the arbitrarily selected chamber 51 among the large number of chambers 51 of the internal drum device 22 is positioned so as to face the ammunition outlet 18a as shown in FIG. Then, from this state, the internal drum device 22 is synchronized with the elevation of the barrel 10. That is, even if the elevation angle of the barrel 10 changes, the positional relationship is maintained so that the ammunition 90 can be delivered from the internal drum device 22 to the ammunition loading device 70 through the ammunition outlet 18a as described later. In this state, the levers 66 and 67 are moved by the actuator 106 from the position shown by the solid line in FIG. 6 to the position shown by the phantom line in the drawing, so that the second clutch 55 engages with the first clutch 54 located above in the drawing,
Further, the third clutch 57 meshes with the lower first clutch 54 in the drawing. When the shot sending input shaft 64 is rotated by a rotating device (not shown), the second clutch 55,
The bullet feed screw shaft 52 of the chamber 51 located at the ammunition delivery port 18a via the first clutch 54, the belt 56, and the pulley 62.
6 rotates the bullet feeding pawl 58, the auxiliary feeding pawl 96, etc.
Move one pitch in the middle left direction. As a result, the leftmost ammunition 90 of the six ammunition 90 is pushed out of the chamber 51 into the loading passage 11. On the other hand, the third clutch 57 is the second clutch due to the gear train and the bullet feed input shaft 65 for the bullet feed tab 58 of the empty chamber 51 located at the lower portion of FIG. By being rotated in the direction opposite to 55, 1 in the return direction to the right in the figure
It can be moved by the pitch. In FIG. 5, the ammunition 90 pushed out from the chamber 51 through the ammunition outlet 18 a and into the loading passage 11 is delivered to the pawl portion of the chain 77 of the elevator device 76. The chain 77 is moved by being driven by a drive device (not shown), and the ammunition 90 is delivered to the blasting star wheel 78 located at the end of the loading passage 11.
The sending star wheel 78 delivers the ammunition 90 to the sending star wheel 80 by being driven by a rotating device (not shown). The delivery star wheel 80 is driven by an intermittent drive device (not shown) to rotate in one direction at a predetermined rotation angle (120 degrees in the case of example) in a predetermined cycle and stop at that position. While delivering the ammunition 90 to the loading device 100,
The next recess will be at the ammo receiving position. The play bottom 82 of the loading device 100 feeds the ammunition 90 received at the ammunition receiving position to the loading position by the rotation of the cam drum 84, loads the ammunition 90 into the medicine chamber 74a (see FIG. 1), and returns to the ammunition receiving position again. When all the six ammunition in one chamber 51 are delivered to the loading device 70 by repeating the above operation, the internal drum driving device 48 is rotated by a predetermined rotation angle, and the next chamber 51 is positioned at the delivery port. The same operation as is repeated. The chamber 51 emptied by delivering the ammunition 90 is replenished with the ammunition 90 from the ammunition replenishing device 56 at a predetermined replenishment position. In the ammunition supply device of the present invention, since the ammunition is supplied regardless of the turning of the gun, it is not necessary to dispose the ammunition box around the turning mechanism. Therefore, the ammunition supply device 18,
It suffices that ammunition can be supplied in a state of being synchronized with the elevation of the gun by means of Nos. 19 and 19, and it is not necessary to provide a device having a large moving space such as a flexible chute.

In the above description of the embodiment, the sending star wheel 80 is intermittently driven in one direction.
It is also possible to intermittently make the sending star wheel 80 oscillate. That is, the delivery star wheel 80 rotates in one direction by a predetermined rotation angle (120 degrees in the case of embodiment) in a predetermined cycle by an intermittent rotation device (not shown), and stops at that position. In the same manner, the intermittent rocking motion of repeating a predetermined rotation angle in the opposite direction at a predetermined cycle and stopping at that position is repeated. Such an operation can be performed when the same type of bullet as the bullet feeding devices 18 and 19 are being fed. This allows two ammunition supply devices 18,
The ammunition 90 can be delivered to the dispatching star wheel 80 alternately from 19 and 19.

[0013]

As described above, according to the present invention, it is not necessary to provide a device such as a conventional flexible chute that requires a large operating space, and therefore the device can be made compact. Since the ammunition transport distance can be made remarkably shorter than the conventional one, the number of shots per unit time can be increased.
