Since the conventional automatic fire tube feeding device for a split screw type closing machine is configured as described above, the following problems exist. In other words, the supply of fire tubes in a conventional artillery equipped with a separate screw-type closing machine is a method in which the fire tubes are supplied by hand one by one. There are two types of systems: discharge when the fire tube closing machine is opened in conjunction with occasional operation, and opening and discharging the fire tube closing machine by hand. Therefore, there was a method of discharging the fire tube in conjunction with the opening of the closing machine. However, since there is only a method of supplying (loading) the fire tube one by one by hand, a split screw type closing machine is used. With the equipped artillery, automatic supply of fire tubes (automatic loading) could not be performed, and it was difficult to adopt automation of the gun system. In addition, in order to manually supply or discharge the fire tube, the gunner must go to the gun side after loading ammunition and firing, and manually supply (load) the fire tube which is a dangerous material. Was supposed to do very dangerous acts. In an artillery system that discharges a fired tube after firing in conjunction with the opening operation of a closed machine, the discharged fire tube enters the movable part of the loading machine or the feeder, causing malfunction. And fire was interrupted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In particular, a plurality of fire tubes are loaded into a revolver-type magazine, the fire tubes are automatically supplied, and continuous shooting is possible. It is an object of the present invention to provide a fire tube automatic supply device for a split screw type closing machine which improves safety and reliability.
