In Fig. 2, reference numeral 440 denotes a main retreat seat (buffer).

Referring to the shell loading process of the mortar shell automatic loading apparatus according to an embodiment of the present invention having such a configuration as follows.

[Shell forwarding and clamping process]

First, the shell (S) to be triggered is mounted on the transfer tray 200 of the automatic loading device (1), and then driving the transfer motor 130, the screw 140 connected to the transfer motor 130 is rotated in place At this time, the ball nut 230 formed on the bottom surface of the mounting tray 210 of the transfer tray 200 coupled to the screw 140 is linearly moved.

Accordingly, as shown in FIGS. 13A and 13B, the transfer tray 200 is transferred along the guide rail 110 of the fixed body 100. Guide members 220 are formed on both sides of the mounting bodies 210 of the transfer tray 200, and are coupled to the guide rails 110 of the fixed body 100 so as to be slidably moved, and the transfer tray 200 is guided. .

As such, the transfer tray 200 is passed through the inside of the cradle 310 forming the link assembly 300, both sides of the transfer tray 200 is dug by a predetermined length in the longitudinal direction to serve as a locking step While pushing the first link 320, and the shell (S) is advanced to the clamping position, and transported to maintain the contact state on both side surfaces of the first link 320 and the transfer tray 200 pushed.

As shown in FIG. 6, the first link 320, the second link 330, and the guide pin 340 are provided in both sides of the holder 310 when passing, such that the transfer tray 200 is advanced. While pushing the first link 320, and accordingly the second link 320 is rotated about the rotation axis 331 to move the guide pin 340 forward.

The guide pin 340 pushes the slider 512 in contact with the end of the slider 512 provided in the pedestal 510 of the fixing assembly 500 while moving forward, and the hinge rotor connected to the slider 512. 520 and the hinge bracket 530 disposed below the rotary shaft 533 is rotated about the rotation shaft 533, the front end portion is moved downward.

Then, the hinge bracket 530 is engaged with the hinge locking member 540 located below it. In other words, the front end portion of the hinge bracket 530 is slightly pushed in contact with the hinge catching member 540, and then the hinge catching member 540 rotates slightly around the hinge shaft 542 and retracts accordingly. 530 is to be engaged with the hinge locking member 540 while moving further downward.

At this time, the hinge locking member 540 in the slightly retracted position is returned to its original position by the elastic member 543.

While the hinge bracket 530 is moved downward to engage the hinge locking member 540, the connector 550 coupled to both rear ends of the hinge bracket 530 is moved upward, and thus the connector 550 and Clamps 562 of the clamp assembly 560, which are coupled to each other, are clamped to fix the entered shell S while being collected inward.

The clamp 562 is rotated through the hinge shaft 561 while compressing the elastic member 563 and fixed to both sides of the shell (S).

[S shell loading process to barrel]

As such, in the state in which the shell S is fixed by the clamp 562, the shell S is inserted into the barrel 410 of the barrel assembly 400 positioned below it, which is first loaded in FIGS. 13C and 15A. As described above, the fixing assembly 500 is moved forward in the state in which the shell S is fixed by the clamp 562 by the operation of the actuators 570 located at both edges of the fixing body 100.

Looking at the operation of the actuator 570, the reduction gear portion 572 is rotated by the operation of the drive motor 571 formed in the rear of the fixed body 100 to rotate the rotary tube 573 in place, and then the rotary tube 573 The feed screw 574 inserted into the inside of the) is moved forward to exit the rotary tube 573, and the fixing assembly 500 is moved forward.

As shown in FIG. 12, the reduction gear unit 572 rotates first with the driving gear 572a connected to the driving motor 571, and then the first transmission gear 572b disposed on both sides of the driving gear 572a. And the second transfer gear 572c rotates sequentially, and the third transfer gear 572e rotates while the small gear 572d coaxially connected to the second transfer gear 572c rotates, thereby rotating the third transfer gear ( The rotary tube 573 connected to the 572e is to rotate.

On the other hand, as shown in Figures 11a and 11b on both sides of the fixed assembly 500 moved forward. Rotating cover 565 is provided, the inner side of the rotating cover 565, the rotating bracket 564 is rotatably coupled with the rotating shaft 566, the rotating bracket 564 and the rod 580 It is connected through the connecting piece 582, so that the rod 580 moves forward with the forward movement of the fixing assembly 500, and then, the fixing bracket 420 and the rod (the lower barrel assembly 400) The locking step 581 formed at the end of the 580 is caught and does not move.

As shown in FIG. 15A, when the rod 580 is caught by the fixing bracket 420, the rotation bracket 564 is pulled out to rotate downward about the rotation shaft 566.

In other words, in the state of FIG. 15A, as shown in FIGS. 15B and 15C, the longitudinally long rotating bracket 564 is positioned in the horizontal direction while rotating.

At this time, the rotary link 592 formed on both sides of the mounting member 590 coupled with the rotary bracket 564 also rotates about the rotation axis 595, as shown in Figure 15b, of the rotary link 592 The length of the fixing assembly 500 is moved downward by the length so that the shell (S) is aligned to the loadable position on the inlet side of the barrel (410).

At this time, the fixing assembly 500 is pushed back while meeting the lower end 541b of the rotating member 541 meets the inlet end of the barrel 410 in a fixed state, and then the upper side of the rotating member 541 ( 541a pushes the hinge bracket 530 upward.

At this time, the lower end 541b of the rotation member 541 is moved upward and pushes the lower end of the hinge locking member 540 so that the hinge locking member 540 is moved downward to make the hinge bracket 530 and the hinge locking member easier. Break the coupling between 540.

Accordingly, as shown in FIGS. 16B and 16C, the hinge catching member 540 is locked with the hinge bracket 530, and the clamp 562 of the clamp assembly 560 is then resembled by an elastic member ( 563) is released by the repulsive force to release the clamping state of the shell (S).

At the same time, while the upper end of the clamp 562 is moved downward, the connector 550 coupled with the upper end is also simultaneously moved downward, and thus the right hinge locking member 540 of the hinge bracket 530 coupled with the connector 550 is thus moved. While moving upward, the hinge rotator 520 located thereon is moved upward to return to the original position as shown in FIG. 7A.

In this case, the shell S is partially inserted into the barrel 410. In this state, the barrel assembly 400 is upwardly and inclined so that the shell S is continuously inserted and loaded into the barrel 410. It becomes a triggerable state.

16D illustrates a state in which the shell S is inserted into the barrel 410. In this case, both the barrel 410 and the autoloader 1 are disposed to be inclined at 45 degrees. It is shown as.

Shell (S) is gradually moved downward while rotating by the spiral portion formed inside the barrel (410).

On the other hand, when the loading process of the shell (S) is completed, the fixed assembly 500, which was moved downward, is returned to its original position, as shown in Figure 17, the transfer by the reverse rotation of the rotary tube 573 forming the actuator 570 As the screw 574 is continuously inserted into the rotary tube 573 and the length thereof is contracted, the fixing assembly 500 connected with the feed screw 574 is also reversed.

At this time, the rotating bracket 564 formed on both sides of the backward fixed assembly 500 meets the stopper 430 protruding in front of the barrel assembly 400, and when the feed screw 574 continues to contract, the rotating shaft As the rotation bracket 564 is rotated (clockwise in the drawing) about 566, the rotation bracket 564 rotates on the inclined surface 432 of the stopper 430.

At the same time, although not specifically illustrated in FIG. 17, as shown in FIG. 2, the rotary link 592 connected to the mounting member 590 formed in front of the fixing assembly 500 also rotates about the rotation axis 595. The fixing assembly 500 is moved back while being moved up.
