Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a transfer mechanism for transferring a long object used in an ammunition device such as a weapon or a feed ammunition loading device.

(B) Conventional technology Conventionally, in-vehicle turret guns were often sent manually due to space limitations, small and light ammunition, and a small number of carried ammunition.

(C) Problems to be Solved by the Invention In recent years, along with the increase in size of ammunition, there has been a demand for improvement in firing speed and continuous firing and labor saving, and it has become mechanized.
There are many types of bullets that are sent directly to a fixed interceptor, or a large-scale device is created by the automation of the shots, requiring many shots and time.

Recently, the number of types of ammunition handled has been increasing, and it has become necessary to selectively send bullets, but conventionally, it was necessary for a human to select the bullets to be sent.

An object of the present invention is to provide a compact transfer device and a safe and reliable high-speed transfer mechanism.

(D) Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention provides a bullet tray with an arm swinging mechanism, an arm slide mechanism, a bullet clamping mechanism, a bullet tray elevating mechanism, and a bullet shutter mechanism. It is possible to carry in, carry out, select, and guide bullets from bullet feeders on the top, bottom, left and right of the bullet tray. That is, the present invention is a tray that has a guide surface for a long object that is a straight line in the front-rear direction and has a left-right arc shape, and that is held so that it can be moved up and down, a shutter that guides the movement of the long object in the longitudinal direction, and the length of the long object. The supporting arm holds the arm so that it can be swung up and down left and right, and the spindle is installed in the center of the arc of the tray, and the front end of the spindle holds the yoke so that it can swing back and forth, and before swinging left and right together with the spindle. The clamp arm and the rear of the support shaft are provided with a rear clamp arm that holds the yoke so that it can swing back and forth, swings left and right together with the support shaft, and is slidable. The long object transfer mechanism is characterized by transferring in a downward direction and a downward direction.

(E) Action Long objects with different lengths, such as bullets, inserted from the rear of the tray in the standby (elevated, neutral) position of the tray, from the warhead side, are grabbed in the long-axis direction and oscillated to the left or right or to the middle stage and After descending to the lower stage, it swings and is transferred to an arbitrary set position.
Further, the tray is moved to an arbitrary set position, the bullet at that position is grabbed in the long axis direction, taken out, and transferred to the standby position or another position.

(F) Embodiment One embodiment of the present invention will be described below with reference to the drawings.

The tray 1 has a flat surface in the front and rear and an arcuate long object in the left and right, for example, a guide surface 3 for a bullet 2, and a rear end is held by a guide 4 so that the trailing end can be moved up and down, and is moved up and down (standby position), middle and lower. It can be driven by the device 5 and stopped at each stage. The shutter 6 attaches to the left and right of the guide surface 3 so as to guide the falling of the bullet 2 to the left and right when the bullet 2 is moved in the long axis direction, and opens when the bullet 2 is moved in the horizontal axis direction. It can be driven by 8.

The support shaft 9 is rotatably installed in the tray 1 centered on the arc of the guide surface 3, the front end is connected to the front clamp arm 10, the rear part is connected to the rear clamp arm 11, and the front and rear clamp arms 10 and 11 are connected to the rear end. An oscillating drive device 12 with a gear is provided which swings upward in the left or right direction to prevent a force from the load side (hereinafter referred to as no back).

The front clamp arm 10 is provided with a U-shaped yoke 13 so that the lower front part of the bullet 2 can be swung in the front-rear direction and grasped. The clamped state (upright and closed position) is held by a no-back link 14, and the yoke 13 is Can be opened and closed with cylinder 15.

The rear clamp arm 11 is provided with a Y-shaped yoke 16 so as to grab the rear end surface of the bullet 2 by swinging in the front-rear direction. The clamped state (upright and closed position) is held by the no-back link 14, and the yoke 16 is held by the cylinder 15. A slide drive device 17 is provided which can be opened and closed with the support shaft 9 and can be swung left and right by the support shaft 9 and which slides the rear clamp arm 11 back and forth according to the length of the bullet 2.

The slide drive device 17 is provided with a cylinder 18 with a rack that is held slidably and slidably held between the swing support portion of the rear clamp arm 11 and the support shaft 9, and the cylinder 18 via a pinion 19 and a no-back gear. The structure is such that the pushing force always works when the bullet is clamped.

Each of these devices can be continuously operated by a position detection switch, a control valve, and the like (not shown).

(G) Effect of the Invention A bullet guide function in which a shutter 6 is provided on a tray 1 and can be opened and closed by a cylinder 8, a left and right bullet selecting function in which the front and rear clamp arms 10 and 11 can be swung left and right by a swing driving device 12, and a rear clamp Bullet length matching function that allows 11 to be slid back and forth by drive device 17, bullet attachment and detachment function that allows yokes 13 and 16 to be provided on front and rear clamp arms 10 and 11 to be opened and closed by cylinder 15, and lift drive device that is provided with guide 4. By operating the up / down selection function that allows you to move up and down freely with 5, the left and right, top, middle, and
It became possible to freely transfer bullets from the bullet feeder in the lower row.

With the U-shaped yoke provided on the arm (front), it is possible to securely clamp even bullets having different front outer diameters of the bullets, and the bullets can be swung upward around the arc center of the tray.

No-back gear and no-back link are provided for each mechanism of arm swing, arm slide, and bullet clamp, and the structure is such that the force from the load side to the drive side is not transmitted.
Has excellent impact resistance.

The bullet tray became compact by incorporating the arm slide mechanism inside the arm swing mechanism.
