Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ignition tube recovery mechanism, and more particularly to a novel improvement for automatically recovering an ignition tube after a projectile has been fired.

[0002]

2. Description of the Related Art Conventionally, in this type of launching apparatus, an ignition tube after a projectile has been launched jumps out of a tube tail ring and is scattered on the ground or the like.

[0003]

Since the conventional launching apparatus is configured as described above, there are the following problems. In other words, the ignition tube after the projectile is launched, jumps out one after another by the ignition tube extraction mechanism, is scattered on the ground, etc., and was manually recovered after firing, so all must be recovered manually, and the work is It was a great struggle.
In addition, during the launch of a projectile, the next projectile must be brought in one after another. Sometimes it was in a state.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and more particularly, to provide an ignition tube collection mechanism for automatically collecting an ignition tube after a projectile has been fired. Aim.

[0005]

SUMMARY OF THE INVENTION An ignition tube recovery mechanism according to the present invention comprises a closing device opening / closing mechanism provided on a tube tail ring and comprising a plurality of gears, and an ignition tube extraction mechanism provided on the tube tail ring for taking out an ignition tube. A hollow case rotatably provided on the barrel tail ring, a return spring for returning the case, and a vertical movement in conjunction with a cam of the closing mechanism opening / closing mechanism, and connected to the case. And an ignition tube extracted from the ignition tube extracting mechanism is guided into the case by rotating the case in conjunction with the closing device opening / closing mechanism. further,
An ignition tube collection pocket is provided in the cylinder tail ring or the fixed portion, and the ignition tube passing through the case is collected in the ignition tube collection pocket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an ignition tube recovery mechanism according to the present invention will be described below with reference to the drawings. In FIG. 1 and FIG. 2, what is indicated by reference numeral 1 is a barrel tail ring, and a closing machine (not shown) comprising a plurality of gears 2, a manual opening crankshaft 3 and a closing machine opening crankshaft 4 on the upper part of the barrel tail ring 1. There is provided a closing device opening / closing mechanism 5 for opening / closing the door. A cam 6 provided on the manually opened crankshaft 3 is in contact with a roller 8 of a link 7 operably provided on the closing device opening / closing mechanism 5, and a connecting rod 9 is connected to a lower portion of the link 7. Have been.

The first damper 1 is provided below the connecting rod 9.
0 is connected to a hollow case 11, and the case 11 is connected to a shaft support 12
Thus, it is rotatably provided at a position shown by a solid line and a dotted line in FIG.

An inlet 11a is formed at an upper portion of the case 11, and an outlet 11b is formed at a lower portion thereof. A connecting portion 11c provided on the outlet 11b side is connected to the shaft support portion 12. . A return spring 14 composed of a tension spring is provided between the connecting portion 11c and the locking portion 13 of the tube tail ring 1, and automatically returns to the return position B after the case 11 is tilted to the catch position A indicated by a dotted line. This is a configuration for performing a return operation at the time. Further, the connecting portion 11
c is a configuration that comes into contact with the hydraulic damper 11A.

A box-shaped ignition tube collection pocket 2 is provided directly below the cylinder tail ring 1 or on the fixed part 40.
0 is provided, and the ignition tube 21 of the butt shell discharged from the outlet 11b of the case 11 is recovered. The ignition tube 21 taken out from the tube tail ring 1 is extracted by a well-known ignition tube extraction mechanism 30 provided in the tube tail ring 1. The case 11 is thrown in a state of protruding into the entrance 11a of the case 11 located at the catch position A. The above-described case 11 is configured as shown in FIG. 3, and has an overall L-shaped duct shape.

Next, the operation will be described. First, after the launch vehicle is fired, when the closing machine opening crankshaft 4 rotates in the closing machine opening direction C, the manually opening crankshaft 3
Rotates in the direction of arrow D, and the link 6 is raised by the cam 6 in the direction of arrow E. This rising causes the connecting rod 9
Rises, the case 11 tilts from the return position B to the catch position A via the connecting portion 11c, and at the same time, the ignition tube 21 after the projectile is fired moves from the ignition tube extraction position F of the ignition tube extraction mechanism 30 to the entrance of the case 11 The ignition tube 21 is thrown toward the ignition tube collection pocket 2 from the outlet 11b.
Collected within 0.

When the firing of the ignition tube 21 into the case 11 is completed, the timing at which the engagement between the cam 6 and the roller 8 is released is reached. The case 11 automatically returns from the catch position A to the return position B. Therefore,
The ignition tube 21 can be automatically collected by repeating the above-described operation every time the flying object is fired.

[0012]

The ignition tube recovery mechanism according to the present invention is constructed as described above, so that the following effects can be obtained. In other words, the ignition tube of the shell after the projectile is fired is automatically collected through the case, scattering of the ignition tube as in the conventional case is prevented, and the safety of the operator etc. can be greatly improved. Was.
