Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a coin processing and counting machine which prevents jams during pick-up and transport by rotating coins with different diameters for different denominations. Regarding prevention devices.

[Conventional technology]

1 and 2 show a conventional coin handling and counting machine, in which a pick-up plate 1 includes:
A large number of pick-up portions 2 are arranged in which circular notches are formed at equal intervals in the circumferential direction on the outer periphery.
This pick-up plate 1 is fixed to a shaft 3 and rotates on a surface inclined upward and backward. A select plate 5 is fixed to the shaft 3 with a slight gap on the back side of the pick-up plate 1, and the pick-up portion 2 is attached to the outer periphery of the select plate 5.
A U-shaped receiving portion 4 is arranged in exact correspondence with the above.
A fixedly placed partition plate 6 is interposed in the gap between both plates 1 and 5, and the upper part of the partition plate 6 has a space corresponding to the pick-up part 2 and the U-shaped receiving part 4. A fan-shaped notch is provided. Also, on the back of the select plate 5, there is a shaft 3.
A rotary disk 12 is attached to the rotary disk 12, which is rotatably mounted on a shaft.

On the other hand, the rotation of the drive motor M is transmitted to the gear 18 via the pinion 17 on the shaft 16, and the shaft 3 is rotated. The rotation of shaft 3 is controlled by pulley 19 and belt 2.
0, the subshaft 3 by a power transmission mechanism such as a pulley 21.
a, and the rotary disk 12 is further rotated by a power transmission mechanism such as a pulley 22 and a belt 14.
The rotation of the rotating disk 12 is set slightly farther than the rotation axis 3 of the plates 1 and 5.

In the figure, 9 indicates a guide ring surrounding the outside of the pickup plate 1, and 15 indicates a housing.

In the above device, insert a coin into the guide ring 9 from the input hopper and turn on the start switch 24.
Then, the pick-up plate 1 rotates in the direction of arrow A in FIG. 1, and the pick-up section 2 picks up the coins 23 and conveys them upward one by one. There is a fan-shaped notch in the partition plate 6 at the top, and the coins passing through this fall down and are accommodated in the U-shaped receiver 4 of the select plate 5, which is rotating at the same time.
It is conveyed to the sorting cam section and is sorted and counted.

[Problem that the invention seeks to solve]

The above-mentioned conventional coin handling and counting machine has a problem in that various coins are jammed during its operation. This mainly occurs when the coin does not pass through the fan-shaped notch in a timely manner because the partition plate 6 is stationary and the pick-up part 2 is rotating when the coin falls into the U-shaped receiving part 4. This is because the coin is squeezed between the edge of the notch on the leading side in the rotational direction of both plates and the training side edge of the pick-up part 2 or the U-shaped receiving part 4, which means that the coin crosses the notch. This is due to the fact that the road continues to move forward on an incline.

In addition, since the trailing side edge of the fan-shaped notch is located in front of the top point, the coin passes through the gap between both plates, falls to the trailing side, and falls into the U-shaped receiver 4 one space behind. There is also the problem that two coins may sometimes enter one receiving section, causing a jam or incorrect sorting and counting.

Furthermore, the trailing side edge of the notch tilts backward (in the direction of rotation) in the centripetal direction, but if the tilt angle is small, the outer peripheral surface of the coin will come off the trailing edge of the pick-up part and cannot be pushed, resulting in a jamming phenomenon. induce. On the other hand, if the angle of inclination is large, the falling position will change significantly depending on the size of the coin, making it unstable and unreliable.

The present invention improves the problems of the conventional coin handling and counting machines described above, and provides a jam prevention device that can eliminate all causes of jams by devising the shape of the fan-shaped notch of the partition plate. The purpose is to

[Means for solving problems]

In order to achieve the above object, the present invention interposes a partition plate in the gap between the pick-up plate and the select plate, and a fan-shaped notch provided on the outer periphery of the partition plate extends between the rear edges of both plates in the rotational direction. It is configured to be inclined rearward in the centripetal direction, and to form a stepped portion protruding in the centrifugal direction at the front portion in the rotational direction of the arcuate bottom portion formed in the fan-shaped cutout portion.

[Effect]

In the present invention, the slope of the rear edge of the notch makes it possible to drop the coin into the U-shaped receiving part in a timely manner, and the stepped part prevents the coin from standing in a standing position, which causes jamming. This can reliably prevent intrusion into the gap between both plates.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The structure and function of the pick-up plate 11, pick-up section 2, select plate 5, U-shaped receiving section 4, rotary disk 12, etc. are the same as before, so their explanation will be omitted.

The fan-shaped cutout e provided at the top of the partition plate 6 is
The fan notch e has the shape shown in FIG.
and is formed so that lines extending in the diametrical direction It is provided and integrally formed continuously with the front side edge 8 thereof.

In this embodiment, the coins 23 that are picked up by the pick-up section 2 and transported upward slide on the partition plate 6. Then, when passing through the upper sector-shaped notch e, it falls into the lower U-shaped receiving part 4. At this time, as shown in FIG. It is possible to stand at right angles to 5. In the conventional case, the jamming phenomenon was induced by both plates 1 and 5 and the front edge 8 of the notch, but due to the presence of the step 11, the coin 23 standing upright
Since the coin 23 loses its balance and falls down, it is ejected into the guide ring 9 again to prevent jamming.

In addition, as shown in FIG. 6, there is a possibility that the coin 23 is caught in the gap between the plates 1 and 5, and in this case, the rear side of the coin is inclined downward, and the rear edge of the U-shaped receiver 4 and the front side of the notch are The jam phenomenon was induced at edge 8. In this case as well, the stepped portion 11 pushes out the pinched coins outward in advance and drops them into the U-shaped receiving portion 2, so that they do not jam when passing through the rear edge 8.

Furthermore, as shown in FIGS. 7 to 9, when the transported coin 23 passes through the upper diameter X portion, that is, when it passes the top dead center and moves downward, it is still behind the notch e. The coin is received by the edge 7, but as it moves, the amount of the received coin 23 decreases from the bottom side of the coin 23, and as shown in FIG.
The bottom part tilts downward using the point as a fulcrum. The outer peripheral surface of the coin comes off from the C _a surface of the pick-up section 2. Still C _b
It advances by being pushed by the surface, and eventually its own weight and rotating disk 1
2 and falls completely into the U-shaped receiver 4. In this case, even if there is a delay in the fall, there is still enough room for one coin in the notch e, so the timing of the fall is perfect.

In the conventional type, since the side edge 7 of the notch e is located forward of the diameter X, the coin that enters the notch e tends to fall in the opposite direction, reducing the advancing speed, and when the timing is right, both coins fall. It may slip through the gap between plates 1 and 5 and fall into the U-shaped receiver next to the next one. In this case as well, two coins are placed in one receiving portion 2, causing jamming or alternate counting.

Also, if the angle α of the rear edge 7 is small, that is, if you are standing up, the coin may tilt from the rear.
If the angle α is large, the falling position will change significantly depending on the outer diameter of the coin, making it unstable and reducing reliability. .

In the embodiment, since the rear edge 7 of the notch e is set at a position where it is divided back and forth around the diameter X, the above phenomenon can be completely prevented.

〔Effect of the invention〕

As described above, the jam prevention device of the coin handling and counting machine of the present invention tilts the rear edge of the notch provided in the upper part of the partition plate interposed in the gap between the pick-up plate and the select plate backward in the centripetal direction. Since the front side part is configured with a stepped part that protrudes in the centrifugal direction, the above-mentioned inclination allows the coin to fall reliably into the U-shaped receiving part in a well-timed manner. It becomes possible to eliminate the standing state of the coin and push out the coin that has entered between the two plates. the result,
It is possible to reliably prevent the jamming phenomenon that occurs in conventional devices.
