2. Description of the Related Art Conventionally, this type of explosive holding mechanism has been used as a vertical upward opening machine shown in FIG. 3 and a horizontal horizontal opening machine disclosed in Japanese Patent Publication No. 7-81797 and shown in FIG. A configuration can be given. That is, in the case of the configuration shown in FIG. 3, the cylinder tail ring 1A of the combustion chamber 2 of the firing cylinder 1
A stopper 4 having an explosive stopper 3 for stopping is provided on the lower side, and the rear end 5a of the explosive 5 in an inclined state is locked.
Was prevented from falling.

In the case of the configuration shown in FIG. 4, after the gunpowder 5 conveyed by the gunpowder tray 7 is transferred to the combustion chamber 2 near the cylinder tail ring 1A of the firing cylinder 1 having the closing machine 6, the An explosive stopper 11 is provided, which is movable forward and backward by an explosive stopper drive unit 10 comprising: The explosive stopper 11 prevents the explosive 5 from dropping.

[0004]

The conventional explosive holding mechanism has the following problems because it has been configured as described above. That is, in the case of the configuration shown in FIG. 3, the gunpowder stopper is for manual transfer, and the hander can only confirm that the gunpowder has stopped falling. Also, this gunpowder stopper was shallow, and the reliability of the gunpowder stopper alone was inferior for mobility transfer. In addition, in the case of the configuration shown in FIG. 4, when applied to a vertically upward-opening-type cylinder-end device, a notch is required in the tray to avoid interference with the front end of the transfer tray, and the transfer may be unstable. Was. That is, it can be applied only to a horizontal horizontal opening machine, and its application range is limited.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and in particular, pivots a stopper in a closing machine between a developing position and a storage position in conjunction with the vertical movement of a gunpowder transfer mechanism and the closing machine. It is an object of the present invention to provide an explosive holding mechanism capable of improving the transfer performance.

[0006]

SUMMARY OF THE INVENTION An explosive holding mechanism according to the present invention transfers an explosive to a combustion chamber of a launch cylinder having a closing machine,
In the explosive holding mechanism in which the explosive is prevented from dropping by a movable stopper, a cam plate is turned in conjunction with an explosive transfer mechanism for transferring the explosive, and the cam plate is rotatably provided on the closing machine. The stopper is turned from the extended position to the retracted position by the movement of the crank roller engaged with the cam groove of the cam plate in conjunction with the operation of lowering the closing machine by rotating the stopper to extend to the extended position. Is moved, the closing machine can be located at the closed position, further, a stopper extension roller provided on a rotating shaft that rotates in conjunction with a stopper extension cam of the explosive transfer mechanism,
And a cam plate return roller, a belt interlocked with the rotation of the stopper extension roller, the cam plate return roller, and the rotation shaft,
An engaging body that rotates the cam plate in conjunction with the rotation of the belt, and a cam plate return cam surface provided at a lower portion of the closing machine, wherein the closing machine descends and closes, The cam plate return cam surface and the cam plate return roller are engaged with each other to rotate the engagement body, and the cam plate is forcibly returned to the cam plate return position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an explosive holding mechanism according to the present invention will be described below with reference to the drawings. The same or equivalent parts as those in the conventional example will be described with the same reference numerals. In FIG. 1 and FIG. 2, a reference numeral 1 denotes a firing cylinder. A stop body 4 having an explosive stopper 3 for stopping an explosive 5 is provided on a tail ring 1 </ b> A of the firing cylinder 1 where a combustion chamber 2 is located. A closing machine 6 for constituting the closing machine is provided so as to be able to move up and down along the direction of arrow A.

On the inner wall of a guide path 20 for guiding the explosive 5 of the closing machine 6, a stopper 11 for stopping the fall of the explosive 5 is rotatable via a shaft support 12 as shown by a solid line and a dotted line. The stopper 11 is located at the extension position B
To stop the explosive 5 and store it in the recess 21 at the storage position C.

The stopper shaft 22 of the stopper 11 is connected to a gear 23 having a crank roller 24. The crank roller 24 projects outside the closing device 6 and is rotatable by a support shaft 25 in a cam groove 27 of a cam plate 26. Is engaged. The engagement hole 27 in the upper part of the cam plate 26 is
The cam plate 26 is configured to rotate at a cam plate return position D shown by a solid line and a dotted line by the rotation of the engagement member 30.

The lower end of the belt 28 is engaged with a pulley 32 of a rotating shaft 31.
A stopper extension roller 33 and a cam plate return roller 34 are provided so that the directions are different from each other, and an explosive transfer mechanism 40 is provided so as to be able to return in a direction orthogonal to the rotation shaft 31. A lower end of the explosive transfer mechanism 40 is provided with a stopper extension cam 35 engageable with the stopper extension roller 33.

Next, the operation will be described. First, gunpowder 5
In the state of FIG. 1, when the explosive transfer mechanism 40 holding the explosive 5 is advanced along the arrow in the state of FIG. 1, the stopper advance cam 35 rotates the stopper advance roller 33 in the direction of the arrow, and at the same time, The cam plate 26 rotates in the direction of the arrow via the rotating shaft 31, the belt 28, and the engaging body 30, and the stopper 11 rotates to the extension position B via the cam groove 27, the crank roller 24, and the stopper shaft 22. In this state, as shown in FIG. 2, the explosive 5 is transferred into the combustion chamber 2, and the stopper 11 is engaged with the rear end of the explosive 5 so as to prevent the explosive 5 from lowering.

Next, when the closing machine 6 is lowered to perform the closing operation after the transfer of the explosive 5, the crank roller 24 rotates along the cam groove 27 in the opposite direction to that described above. The stopper 11 is rotated from the extended position B indicated by the solid line to the storage position C via the solid line and is stored in the concave portion 21. When the closing machine 6 is completely closed, the cam return provided at the lower portion of the closing machine 6 is returned. Because the cam surface 41 for use rotates the upright cam plate return roller 34 in the opposite direction to that described above, the rotation shaft 31
The cam plate 26 is rotated in the opposite direction to that described above via the belt 28 and the engagement body 30, the cam plate 26 is returned to the cam plate return position D, the closing machine 6 is completely closed and is located at the closing position F, Preparation for launch is complete. After the firing, when the closing machine 6 is raised, the stopper 11 remains in the concave portion 21,
The next transfer is possible.

[0013]

The explosive holding mechanism according to the present invention is constructed as described above, so that the following effects can be obtained. In other words, by incorporating the stopper in the closing machine, the notch of the transfer mechanism as in the past becomes unnecessary,
Significant improvement in transfer performance can be obtained.
