[0002]

2. Description of the Related Art In a conventional cannon, a bullet supply device for supplying an ammunition to an engine section includes a bullet holding section for storing ammunition, and an ammunition being supplied from the bullet holding section according to consumption in the engine section. Generally, a system including a bullet feeding mechanism for feeding into an engine unit is employed. On the other hand, as a method of ammunition, there are a belt link method in which ammunition is linked by a link, and a linkless method in which ammunition is fed alone.

[0003] As a method of this kind of bullet holder,
The following are mainly known. . The cylindrical container is divided into fan-shaped small rooms as a space for storing ammunition, and belt-link type ammunition is stored in this small room. . Linkless bullets are stored in a cube-shaped container bundled with a bullet. . Attach multiple bullets to the endless chain,
Each of them holds and stores ammunition. . Belt-link type ammunition is layered and stored in a cubic container. . The cylindrical container is divided into layers, and each layer is provided with a bullet chain, on which ammunition is stored.

[0004] The following types are mainly known as types of the bullet feeding mechanism. . A plurality of bullets are arranged on the endless chain to receive ammunition from the bullet holder and send it to the engine. . The bullet feeder wheel is driven to feed the belt link type ammunition from the bullet holding section to the engine section. . The belt-link type ammunition is drawn directly into the engine by the mechanism of the engine.

However, such a conventional bullet feeder has the following technical problems. (1) For belt-link type ammunition, medium- and large-caliber guns require excessive force on the belt link;
Also, because the weight of the ammunition is too large and the movement is limited,
It is not used except in special cases and is used exclusively for small caliber guns.

(2) In the method of bundling linkless bullets with a bullet feeder, the delivery position of the ammunition from the bullet holder to the bullet feed mechanism changes for each bullet bundle, so that the bullet holder and the bullet feeder are used. It is necessary to accurately link the movement of the mechanism. For this reason, a complicated and precise mechanism is required.

(3) The method of holding bullets with a chain requires a large amount of power because the number of ammunition held is limited and the chain is also driven to drive the ammunition. Difficult to respond quickly. (4) In the system in which both the bullet holder and the bullet feed mechanism are driven by a chain, each requires a chain wheel to drive the chain, so the size is inevitably large, and the bullet feeder is made compact. Hinders

[0008] The present invention relates to a medium-caliber or larger cannon.
Use linkless ammunition and aim to achieve the following:・ The mechanism is not complicated and precise. ・ Sends ammunition in quick response to the ammunition consumption of the cannon. ・ Minimizes the power for sending ammunition. ・ Moreover, makes the size of the sending section small.

A pair of horizontal rotating shafts 19 and 34 are vertically rotatably supported by the bullet feeder case 4a and are vertically separated from each other. A chain wheel 35 is fixed to the upper rotation shaft 19, and a chain wheel 33 is fixed to the lower rotation shaft 34. As shown in FIGS. 1 and 2, the lower chain wheel 33 and the rotary shaft 19 are connected to a rotary drive device including a motor 7, chain wheels 13, 15, a chain 14, and a spring motor 6 in which an internal spiral spring is wound. And is driven to rotate.

[0031] Between the pair of chain wheels 33 and 35 arranged in the bullet feeder case 4a, a bullet feed chain 69 is provided.
Is wound. The bullet feed chain 69 is configured by connecting a plurality of T-shaped chain links 32 each having a locking portion 32a so as to form an endless annular chain by a shaft 36 having a roller 37, A roller 30 rotatably supported by a shaft 31 is provided at the tip of the locking portion 32 a of each chain link 32.

It should be noted that such a chain wheel 33,
As shown in FIG. 10, two sets of the feed chain 35 and the feed chain 69 are arranged at a predetermined interval in the center axis direction of the pair of rotating shafts 19 and 34, and a pair of the feed chain 69 connected by the shaft 31. As shown in FIG. 3, locking projections 5b projecting from the engine case 5a of the engine unit 5 to the inside of the bullet feeder case 4a are located on both sides. The lower surface of the locking projecting portion 5b forms a curved surface whose tip portion hangs down gradually, and the ammunition 38 transported by the bullet sending chain 69 is supplied to the bullet supply passage C of the engine portion 5.
It pushes out while guiding in the direction of.

The intermediate portion of the first opening 4c, which opens into the lifting portion 12 of the bullet feeder case 4a, is pivoted by a shaft 28 provided on the upper wall 70 as shown in FIGS. A stopper 29 that is freely supported is provided, and the upper end of the stopper 29 abuts on the outer surface of the bullet feeder case 4a and is allowed to swing in only one direction, and the lower end is located inside the bullet feeder case 4a. It can swing by swinging in the direction. Behind the two chain links 32 corresponding to the stopper 29, a roller guide 75 integral with the bullet feeder case 4a is formed as shown in FIGS. ing.

While the roller 30 of the bullet feed chain 69 is in contact with the lower end of the stopper 29, the springs 23, 47 and the guide portion 24 a of the shaft member 24 act on the bullet feed portion 4. The movement of the ammunition 38 that has been elastically pushed is stopped, thereby preventing interference with the ammunition 38 that has already been pushed into and transferred to the bullet chain 69. At the same time ammunition 3
It is also possible to prevent the next ammunition 38 from being forcibly fed between the adjacent locking portions 32a of the chain link 32 that holds the cartridge 8. When the roller 30 separates from the lower end of the stopper 29, the stopper 29 becomes free, and the ammunition 3
8 is resiliently pushed between the bullet feeding chain 69, specifically, the next locking portion 32 a of the adjacent chain link 32. Further, when the bullet feed chain 69 moves, the roller 30 pushes the lower end of the stopper 29 again, and the supply of the ammunition 38 is stopped. Since the back of the chain link 32 of the roller 30 pressing the stopper 29 is supported by the roller guide 75, the roller 30 reliably swings the stopper 29 to the stop position.

The engine section 5 includes a well-known bullet-feeding wheel 68 rotatably supported in an engine-section case 5a, and a peripheral portion of the bullet-feeding wheel 68 has a predetermined circumferential interval as shown in FIG. Are formed with four concave portions 68a. Then, connected to the lower edge of the second opening 4d of the bullet feeder case 4a, a bullet feed passage C is formed horizontally, and a concave portion 68a of a rotating bullet feed wheel 68 is formed at the tip of the bullet feed passage C. They rotate and move one after another.

The ammunition 38 sent from the bullet feed section 4 into the bullet feed passage C of the engine section 5 enters the recess 68a of the bullet feed wheel 68 which is intermittently stopped, and the subsequent bullet feed wheel 6
The rotation of 8 causes the barrel 1 to be transferred to a position where the center axis coincides with it, and the ammunition 38 is loaded into the barrel 1 by a play bottom (not shown). While the bullet feed wheel 68 is rotating, the ammunition 38 fed from the bullet feed passage C is
Movement is stopped at the peripheral edge of. The ammunition 38 is loaded on the barrel 1, a bullet is fired, and then, with the breech hole retracted by a predetermined amount, the bullet sending wheel 68 turns again, and the next ammunition 38
Can be sent to the concave portion 68a. Thus,
The ammunition 38 pushed into the bullet supply passage C from the bullet sending section 4 is sequentially loaded into the barrel 1 in the engine section 5 and fired.

Next, the operation of the above embodiment will be described. First, the ammunition 38 is supplied to the bullet holder 22. In other words, multiplied Hikitsu hooks 64 and 65 90 ° turning manually operated retraction manually operated to the opening F of the case 54, the locking portion F ₁ of the case 54 as shown in FIG. In this state, the ammunition 38 is sequentially put into the spaces 27b, which will be the respective layers of the bullet holder case 27, from the bottom. Each space 27

From this state, if both the lifting unit 12 and the bullet sending unit 4 are operated in the bullet supply direction by the respective rotary driving devices,
First, sequentially from the ammunition 38 in the lowermost space 27b,
It enters between one pitch of a pair of lifting springs 23 and 47,
The ammunition 38 held between the pair of coils moves upward by the screw action. For this reason, the lifting spring 2 of the ammunition 38
The delivery position to 3, 47 is not specified up and down, and smooth delivery is performed. When the ammunition 38 moves upward, the ammunition 38 rises while being guided by the side surface 53a of each of the locking levers 53 and the boundary wall 4b of the bullet feeder case 4a, and comes into contact with the guide portion 24a of the shaft member 24. Is pushed out toward the bullet feeder 4. In a state where the ammunition 38 exists in the lower space 27b of each space 27b of the bullet holder case 27, the ammunition 38 raises and swings the stopper lever 53 to restrain the movement of the ammunition 38 in the upper space 27b. are doing. Therefore, the resistance force in the lifting unit 12 based on the resiliency of the plurality of push mechanisms 21 is only the push force of the single push mechanism 21. For this reason, the driving force of the lifting unit 12 can be reduced.

In the feeding section 4, the roller 30 is

In the state shown in FIG. 3 in which the bullet feeder 4 has sent bullets, the ammunition 38 has been fed into the bullet feed passage C, and the roller 30 is in contact with the lower end of the stopper 29, the bullet feed chain 69 is moved to the X position.
When the stopper 29 is advanced, the stopper 29 can freely swing. For this reason, the ammunition 38 elastically pressed by the lifting springs 23 and 47 of the lifting portion 12 is pushed between the adjacent locking portions 32 a of the bullet sending chain 69. Further, FIG.
When the bullet feed chain 69 advances by Y from the state shown in FIG. 7, the roller 30 returns the stopper 29 to the position where the ammunition 38 is stopped again. Thus, the pushing force of the ammunition 38 by the lifting unit 12 is received by the rotational frictional resistance of the roller 30 and hindrance of the advance of the bullet sending chain 69 is suppressed. Can be reduced. In addition, there is no interference between the ammunition 38 already pushed into the bullet chain 69 and the next ammunition 38, and the resistance from this surface can be small.

In this manner, the bullet feeding operation is continued until the first ammunition 38 is received in the recess 68a of the bullet feeding wheel 68 of the engine unit 5 and stopped. In the state where the bullet feeding operation is completed in this manner, the ammunition 38 is moved to the bullet pushing mechanism 2 of the bullet holder 22.
1. The spring motor 9 of the lifting unit 12 and the spring motor 6 of the feeding unit 4 are elastically pushed toward the engine unit 5, and the ammunition 38 at the tip is stopped by the feeding wheel 68. Have been.

As shown in FIG. 11, the bullet holder 22 emptied as shown in FIG.
If there is a space 27b, the ammunition 38 is appropriately supplied to the space 27b. When the sending operation is completed in this way, the shooting is started. The shooting during shooting is performed in the same manner. That is, the bullet sending wheel 68 is turned by the shooting, and the concave 68
The first ammunition 38 received in a moves to the next concave portion 68.
When a coincides with the bullet supply passage C and stops, the ammunition 38 elastically pressed by each mechanism moves in the direction of the bullet feed wheel 68 and is fed into the concave portion 68a.

As will be understood from the above description,
ADVANTAGE OF THE INVENTION According to the bullet supply apparatus of the cannon concerning this invention, the following effects are acquired. According to the first aspect of the present invention, a large number of ammunition stored in each stage is reliably and smoothly fed from the lowermost end of the space of the small and simple structure of the bullet holder case. . According to the third aspect of the invention, the feeding of the ammunition in the lifting section is performed by the rotation of a pair of lifting springs composed of coil springs. For this reason, the accommodation space can be reduced,
Also, with enough ammunition and the feed stopped,
Because the elastic thrust by the lifting spring acts on the ammunition being fed, the ammunition can be momentarily pushed out and supplied following the consumption of the ammunition. In addition, since a coil spring is used, precise machining can be omitted, and the weight can be further reduced. In addition, the capacity of the rotary drive can be reduced.

According to the fifth aspect of the present invention, the stop lever is swingably attached to the opening between the lifting portion and the bullet sending portion, and the swing of the stop lever is switched by the movement itself of the bullet sending chain. , And controls the transfer of ammunition from the lifting unit to the sending unit. For this reason, the interference between the ammunition of the lifting section and the ammunition of the bullet sending section is eliminated, and the movement of the bullet sending chain becomes smooth. As a result of the above effects, it is possible to reduce the size of the bullet supply device of the cannon, facilitate the projectile feeding, reduce the required power, and reduce the cost.
