1. Field
Apparatuses consistent with exemplary embodiments relate to a charge feeding apparatus, and more particularly, to a charge feeding apparatus which may quickly feed a charge in order to support automatic fire of a vehicle-mounted self-propelled gun.
2. Description of the Related Art
In modern wars, a self-propelled gun is used as an essential piece of combat equipment to fire projectiles at a target. Shells are loaded on the self-propelled gun, and the self-propelled gun can be moved at high speed between military camps. Each shell is combined with a charge at the rear end thereof and is fired due to an explosive force generated by ignition of the charge in a gun barrel. Thus, charge feeding needs to be quickly performed in order to smoothly perform automatic fire with the self-propelled gun.
In the related art, because a charge loading and transferring process is performed semi-automatically or manually, human operation is unavoidable and considerable time is taken to feed a self-propelled gun with charges.
In particular, in the case of transferring charges loaded vertically in a charge rack, charges that are not extracted at one time are left in the charge rack. Accordingly, it is difficult to remove residual charges by a separate human operation.
One or more exemplary embodiments include charge feeding apparatuses that may quickly transfer a charge to a firing position without any residual charges.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented exemplary embodiments.

As illustrated in
As described above, when residual charges 10′ left in the charge rack 400′ are separately processed, unnecessary time is required to transfer the charges 10′ to the firing position and a separate human operation is required to remove the residual charges 10′. This problem hampers the automation and delays speedup of self-propelled gun firing.
Hereinafter, the configurations and operations of the charge feeding apparatus 1000 according to an exemplary embodiment will be described in comparison with the comparative example 1000′ of
Referring to
The charge 10 stored in the container 100 is transferred by the transferring unit 300 (
Also, the charges 10 are aligned in the container 100 to move in the lengthwise direction (i.e., the X direction) of the container 100 while contacting each other. In this case, in order to induce the contact between the adjacent charges, the container 100 may not beed the partitions 101′ dividing the charges 10′ unlike the container 100′ of the related art as shown in
Both end portions of the container 100 may be opened to an outside thereof. That is, one end portion of the container 100 may be opened to the outside so that a rod 320 of the transferring unit 300 may be inserted into the container 100 through the one end portion of the container 100. Also, the other end portion of the container 100 may be opened to the outside in order to discharge the charge 10 at a discharge position D.
The container 100′ of
The chain link 200 connects the containers 100 disposed in the horizontal direction and in parallel to one another. Because the containers 100 arranged in the horizontal direction and in parallel to one another are connected by the chain link 200, the charges 10 in the container 100 may also be disposed in the horizontal direction. That is, by the chain link 200, the disposition of the charges 10 is converted from a vertical mode to a horizontal mode.
Since the charges 10′ in
Referring to
The chain driver 210 transmits a rotational force to the chain link 200. As an example, chain-sprocket driving may be used to transmit the rotational force. Referring to
As illustrated in
The containers 100 may be respectively disposed in the spaces between sawteeth of the sprocket 240. Accordingly, when the sprocket 240 is rotated by the driving motor 220, the chain link 200 also rotates by engaging with the sprocket 240. As illustrated in
When the chain link 200 rotates, one of the containers 100 is transferred to the discharge position D. Referring to
Referring to
Specifically, the rod 320 is inserted into the container 100 from one end portion of the container 100. As described above, one end portion of the container 100 is opened to the outside so that the rod 320 may be inserted into the container 100.
The rod 320 moves in the lengthwise direction (i.e., the X direction) of the container 100 while pressing the charges 10 stored in the container 100. Accordingly, the charges 10 also move in the X direction together with the rod 320. As described above, in order to guide the movement of the charges 10, the sectional shape of the container 100 corresponds to the sectional shape of the charge 10.
The rod 320 may have any sectional shape such as a circular sectional shape or a polygonal sectional shape, but the end portion of the rod 320 contacting the charge 10 may be flat.
As the rod 320 presses the charge 10 at one end portion of the container 100, the charge 10 at the other end portion of the container 100 is discharged outside the container 100. That is, the transferring unit 300 is configured to discharge the charges 10 sequentially from the charge 10 located at the other end portion opposite to one end portion at which the rod 320 contacts the charge 10. In this case, a rod movement distance d and the number of discharged charges 10 are controlled by a controller 600 as shown in
As described above, the charges 100 discharged from the container 100 located at the discharge position D are stored in the loading container 400.
Referring to
A portion of the loading container 400 may be curved to connect the loading container 400 to the container 100 transferred to the discharge position D. That is, the loading container 400 is configured to vertically load the charges 10 disposed horizontally in the container 100 so that the extractor 500 may easily extract the charges 10.
Also, the loading container 400 includes the opening 410 configured to expose at least some of the charges 10 to the outside thereof. The opening 410 has a length along which the charges 10 are exposed to the outside. Herein, the number of charges 10 exposed to the outside may be equal to the number of grippers 510 of an extractor 500.
The loading container 400 supports the charges 10 exposed to the outside through the opening 410. Thus, the residual charges 10, which are not extracted through the opening 410, may be prevented from falling when some of the exposed charges 10 are extracted by the extractor 500.
The extractor 500 extracts the charges 10 from the opening 410 of the loading container 400.
Referring to
The extractor 500 may include the grippers 510 configured to grip the charges 10 supported by the loading container 400. The grippers 510 may, for example, extract three (3) to six (6) charges 10 independently from the opening 410 of the loading container 400.
Referring to
The controller 600 includes a signal control processor 610 and a rod driver 310.
The signal control processor 610 receives information about a stored number of charges 10 which are stored in the container 100 and generates a control signal according to the information about the stored number of charges 10.
The rod driver 310 receives the control signal and moves the rod 320 according to the control signal. The rod driver 310 moves the rod 320 along the discharge position D in the lengthwise direction of the container 100. The rod driver 310 may be any type that enables the linear movement of the rod 320. For example, the rod 320 may be linearly driven by a linear motor or a rotary motor including a lead screw.
Also, according to the control block diagram of
A process of calculating a target number of charges 10 that should be discharged to the loading container 400 by controlling the rod movement distance d will be described below in detail.
Referring to
The signal control processor 610 provides the control signal to the rod driver 310 to control a driving force applied to the rod 320. As an example, current value of the motor driving the rod 320 may be controlled according to the generated control signal.
As described above, when the rod 320 is moved by the controlled driving force in the lengthwise direction (i.e., the X direction) of the container 100, as many charges 10 as the target number of the charges 20 are discharged from the container 100 and the loading container 400 is filled with the discharged charges 10.
In this case, when the charges 10 in the container 100 located at the discharge position D are exhausted or depleted, a subsequent container 100 is rotatably transferred to the discharge position D. Accordingly, the rod 320 is inserted into the subsequent container 100 and is moved to discharge the charges 10 until the target number of the charges 20 is satisfied.
Based on the illustration of
As illustrated in
Thereafter, as illustrated in
Referring to
Thus, even when any number (among three to six) of charges 10 are extracted, the problem of leaving the residual charges 10 as in the comparative example 1000′ of
As described above, according to the one or more of the above exemplary embodiments, the charge feeding apparatus may transfer the charge to the firing position without any residual charges.
Also, the charge feeding apparatus may quickly transfer the charge to the firing position by automating charge extraction.
Also, the charge feeding apparatus may reduce the charge explosion risk by safely storing the charge in the horizontal direction.
It should be understood that the exemplary embodiments described herein should be considered in a descriptive sense only and not for purposes of limitation. Descriptions of features or aspects within each exemplary embodiment should typically be considered as available for other similar features or aspects in other exemplary embodiments.
While exemplary embodiments have been particularly shown and described above, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the inventive concept as defined by the following claims.
