DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small ball supplying device for supplying small balls to a small ball launching device.

[0002]

2. Description of the Related Art There have been proposed many systems and mechanisms for supplying small balls.
Globules of globules taxiway end as shown in 129069 JP raised by an electric plunger, which feeds the continuous plane road surface as a firing standby position have been proposed.

[0003]

In the prior art, the small ball supplying device and the launching device are combined and used as completely separate units. That is, the small ball supply device has completely different functions from the launching device and the supply device, and attempts to smoothly discharge the small ball by taking electrical timing. However, mechanical matching between the launching device and the supply device requires various adjustments, and in some cases, the timing of supply and launch cannot be taken to cause poor launch.

Accordingly, an object of the present invention is to integrate a small ball supply device and a launching device, to supply small balls by the driving force of the launching device, to prevent supply mistakes, and to minimize the launch timing of the small balls. It is intended to be able to fire.

That is, the present invention solves such a problem.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view of an automatic small ball feeding apparatus according to an embodiment of the present invention.

[0008] globule 1 globules automatic feeder 20 that is integrally attached to the globules launcher 2 to fire is a gas lever 6 for supplying globules 1 to globules launcher 2, the push-up It is consists <br/> by a support portion 21 for supporting the <br/> lever 6 slidably. The disc-shaped disc 3 rolling globules 1 globule launchers 2, the push-up lever 6 disk-shaped cam 4 backward is provided, and also the the disk 3 globules 1 It has a hole 5 for feeding.

FIG. 2 and FIG. 3 are an enlarged view and a side view of an enlarged view showing a main part of the automatic small ball feeding apparatus according to the embodiment of the present invention. The convex portion 4 'of the cam 4 provided on the disk 3 and the hole 5
In this embodiment, the relative positions are substantially as shown in FIG. 2, but may be appropriately arranged in relation to other components. Gas lever 6 to raise selectively to take globules 1 is provided with a receiving portion 12, 13 for receiving a single globule 1 than globules group 8 fed from the globules taxiway 7. Here, since the receiving portion 12 has an inclined surface, the small ball 1 is not only supported in contact with the receiving portions 12 and 13 but also a guide which is a part of the supporting portion 21 for supporting the push-up lever 6. It is also supported by the plate 14. At one end of the push-up lever 6, there is a push-up portion 11 that can be displaced by the cam 4, and at the other end, a plate-shaped guide portion 15 is provided.

FIG. 4 is a cam-push-up lever position diagram schematically showing the movement of the cam and the push-up lever according to the embodiment of the present invention. In the state shown in (a), the push-up lever 6 is at the bottom dead center, that is, at the lowest position, and in the state shown in (a), the push-up lever 6 and the small ball 1 are displaced by the amount by which the shape of the cam 4 is displaced. , When the state of (c) is reached, that is, (a)
When the H amount lifting lever 6 is displaced from the state of
Is rolled and supplied toward the hole 5 of the disk 3 over the guide plate 14.

FIG. 5 is a schematic front view and a side view illustrating the shape of the receiving portion of the push-up lever in the embodiment of the present invention. The dimensions of the receiving portions 12 and 13 of the push-up lever 6 are as follows:
When the radius of the small ball 1 is R, R <L1 <2R is preferable,
L2> R is appropriate.

FIG. 6 is a schematic diagram illustrating a case where small balls are continuously supplied in the embodiment of the present invention. In (A), after one small ball 1 is supplied to the receiving portions 12 and 13 of the push-up lever 6, the push-up lever 6 is driven by the rotational movement of the cam (not shown) to ascend (A). . When the small ball 1 is slightly pushed up, the width 1 of the receiving portion 12 is obtained from the small ball diameter 2R.
Is smaller, the small ball 8 ′ closest to the small ball 1 of the continuous small ball group 8 is the guide portion 1 which is a part of the push-up lever 6.
5 and the push-up lever 6 further rises, and the small ball 8 '
Is in contact with the guide portion 15. When the push-up lever 6 is further raised, the small ball 1 is rolled and inserted into the hole 5 (d). When the rotation of the cam (not shown) further advances, the push-up lever 6 starts to descend, and eventually reaches the bottom dead center, and the small ball 8 'is supplied to the receiving portions 12 and 13 (E).

FIG. 7 is an external view of a plate-like cam in the embodiment of the present invention, and FIG. 8 is an explanatory view showing a change in the amount of movement of the push-up lever in the case of the cam shown in FIG. . The convex portion 4 ′ of the cam 4 that comes into contact with the push-up portion 11 of the push-up lever 6 of the push-up lever 6 has a curved line (about the axis 10) that rotates and drives the disk 3, rather than a smooth arbitrary curve (A). In the drawing, r1 is different from r in curvature), so that the movement of the push-up lever 6 is smoother, and the insertability of the small ball 1 into the hole 5 is improved. Further, depending on the rotational speed of the disk, a linear shape separated from the shaft 10 by a certain distance 1 may be preferable. Lever 6 by each cam shape
Assuming that the maximum movement amount is H, the movement amount of FIG.
(B) and (c) can be represented respectively.

FIG. 9 is a schematic view for explaining the vicinity of a bearing portion provided with a one-way clutch in the embodiment of the present invention. The small ball launcher body is omitted. A bearing 20 for rotatably supporting the shaft 10 is fixed to a small ball launcher main body (not shown and indicated by oblique lines), and the shaft 10 and the disk 3 are fixed to a predetermined one by a bearing 25 and a separate one-way clutch 26. Rotate only in the direction of rotation. In the case of a configuration in which a small ball is fired by rotating the disk once as in the present invention, it is possible to prevent reverse rotation when supplying the small ball and to control vibration during rotation of the disk.

In the present invention, the cam shape is a flat cam, but the same configuration is possible with other shapes such as a flat cam.
Further, if there is sliding friction between the push-up portion 11 of the push-up lever 6 and the cam 4, a rolling member such as a ball bearing may be provided in the push-up portion 11. Further, it is possible to pull back the push-up lever downward.

As described above, according to the present invention, the cam
Small pushed up by the lever pushed up by
The ball is ejected through a hole in the disc that rotates with the cam.
Special timing machine
With no mechanical structure, just mechanical mechanism
Supplying small balls one by one to the launcher in a timely manner
Can be.

Furthermore , a guide is provided below the push-up lever.
By providing a blocking part that suppresses the movement of other small balls on the road
Receive the small balls to be supplied and at the same time identify other small balls.
In fact, it can be made to wait on a taxiway.

Further, this blocking portion is moved to the lower portion of the lifting lever.
On the taxiway with a simple mechanism
The supply of the next small ball can be reliably suppressed.

Also, push up the lever along the surface of the disk.
To move the lever up and down.
Holds small balls securely without providing an enclosure around the edge
be able to.

Still further, the receiving portion of the lifting lever is a small ball.
By inclining toward the supply hole, small balls
Enables automatic pouring into feed holes,
Failures due to clogging can be prevented before they occur.
You.

Since the one-way clutch is provided, the rotation of the disk is smooth and the vibration is small even if there is a load due to a small ball or an external load fluctuation.
