Meanwhile, as illustrated in FIG. 2, the shell loading and discharging device according to the present invention detects each time the shell is introduced and stops the driving motor 31 temporarily to drive the first sensor 70. In addition, when the loading of the shell is completed, a second sensor 80 which detects this and prevents the driving motor 31 from being driven any more is made to automatically stack and discharge the shell.

Referring to the operation of the shell loading and discharge device according to the present invention configured as described above are as follows.

The driving motor 31 is driven by the sensors 70 and 80 when the shell 10 is introduced into the shell stacking frame through the shell entrance 23 through a separate transport device (not shown). As the driving force of the drive motor 31 is transmitted to the drive shaft 33 through the reduction unit 32 and the drive shaft 33 rotates counterclockwise in the drawing, the drive shaft 33 and the driven shaft 43 ( Arrow is moved). At this time, the shell is sequentially mounted on the shell mounting plate 53 installed in the roller chain assembly, and is transported from the driven side to the driving unit side while being mounted thereon. When the first mounted shell reaches the driving unit side (in this case, the shell stacking frame Accumulation is completed) The drive motor is stopped by the sensors 70 and 80. That is, each time the shell is introduced, if the driving motor is stopped by the first sensor 70 and the shell is completely loaded on the loading rack, the driving motor is no longer driven by the second sensor 80.

On the other hand, the roller chain assembly 50 on which the shell 10 is mounted is supported by the bracket, and in particular, the roller of the roller chain assembly is supported by the roller movement guide plate 61 of the bracket 60 so that the chain assembly moves on the shell. The phenomenon of sagging by the weight does not occur. In addition, when the roller chain assembly is loosened or needs to adjust tension due to prolonged use, the tension adjusting rod 66 may be moved forward or backward.

After the shell is loaded in this way, the shell must be transported to the loading device for firing the gun. In this case, when the motor is driven in the opposite manner to the above method, the roller chain assembly moves in the direction of the arrow or the direction, and the shells are sequentially opened. It will be discharged to the shell feeder through.

As described in detail above, according to the shell loading and discharging apparatus according to the present invention, since the shells are stacked and discharged by the chain assembly, the loading and discharge of the stacked shells is quickly discharged. Not only can the equipment be operated efficiently, but also the sensor can be operated to drive the motor in a timely manner, thereby automatically carrying out the accumulation of the shell and the discharge of the accumulated shell.
