Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a type 2 coin sorting device that sorts and receives two types of positive coins, and more particularly to a type 2 coin sorting device that sorts coin diameters using a carrier ham.

(Prior Art) In a conventional two-kind coin sorter that accepts two types of true coins by sorting, two types of coins having different diameters that can sort coins of different diameters are used as a means for mechanically sorting the coin diameters. Cradles are commonly used.

(Problems to be solved by the invention) However, for example, when sorting two kinds of positive coins having different diameters using two cradles having different sizes,
If the large-diameter and small-diameter cradle are arranged vertically on the movable side plate that faces the fixed side plate that defines the coin drop passage, there is a problem that the vertical size of the coin sorting device becomes too large.

In order to solve such a problem, in general, the upper side large diameter cradle is attached to the movable side plate provided on one side of the fixed side plate,
The lower small diameter cradle is attached to the second movable side plate provided on the other side, and the coin passing between the engaging pieces of the upper large diameter cradle is guided to the small diameter cradle through the window of the fixed side plate. is doing. However, there is a problem that the structure becomes complicated as a result of such a configuration.

For this reason, the present invention intends to solve the above-mentioned problems at once by using two carrier arms arranged vertically instead of using two cradle as means for selecting the diameters of two types of coins. To do.

The carrier ram is conventionally known as a coin diameter selecting means as described in, for example, Japanese Utility Model Publication No. 55-50778.

FIG. 4 shows an example of a carrier ram 1 in which the carrier ram 1 shown is a pivot pin on the outer surface of one of two vertically spaced parallel plates (not shown) defining a coin drop path. 2 has an arm portion 1b that is pivotally attached by two and extends from the pivotal support portion 1a to one side, and a balance weight portion 1c.
A coin engaging piece 3 protruding at a right angle from the free end of 1b is provided, and the coin engaging piece 3 passes through an arcuate slot (not shown) formed through one side plate to form a coin between both side plates. The carrier arm 1 is projected into the drop passage and is urged clockwise around the pivot pin 2 in FIG. 4 by the action of the balance weight portion 1c, so that the coin engaging piece 3 is placed on the upper end of the arcuate slot. When engaged, it is always held in the position shown by the solid line in FIG.

A fixed fulcrum piece 4 having an upper arc portion 4a concentric with the pivot pin 2 is fixedly provided on the inner side surface of one side plate, that is, on the passage side surface of the side plate. Therefore, when the diameter of the coin falling in the coin drop passage as shown by the arrow is such that the engaging piece 3 and the upper arc portion 4a of the fixed fulcrum piece 4 can be simultaneously engaged, this coin is 3, the carrier arm 3 pivots downward around the pivot pin 2 due to the weight of the coin, and the upper end of the positive coin is located at the lower cutout portion 4b of the fixed fulcrum piece 4 at the position indicated by the imaginary line 1 '. By passing through the lower side, a positive coin is passed and accepted as shown by an arrow.

However, when such a carrier coin 1 is used, the illegal coin C having a small diameter is engaged with the engaging piece 3 as shown in FIG. The engaging piece 3'is moved as shown by the phantom line C'at the rotational position of the carrier arm shown by the phantom line 1 '.
There is a problem that the illegal coins carried by will pass through the receiving passage as shown by the arrow.

Therefore, even when using the carrier arm, it is necessary to provide a limit lever in order to prevent the above-mentioned malfunction, as in the case of using the cradle.

FIG. 5 shows, for example, 50 based on the above-mentioned conventional technique.
In order to select and accept two types of positive and negative coins A and B of 0-yen coin and 100-yen coin, carrier coins for large and small coins are arranged vertically on the same side plate, and small coins below An example of trial production in which a limit lever is provided for the carrier carrier is shown below.

In FIG. 5, reference numerals 10 and 11 denote two vertically separated vertical side plates, and the coin drop passage 1 is provided between these side plates 10 and 11.
2 is formed. The large diameter coin carrier arm 13 is pivotally attached to the outer surface of one side plate 10 by the pivot pin 14 at the upper position, and the small diameter coin carrier arm 15 is pivotally attached at the lower position by the pivot pin 16. . Each of the carrier arms 13 and 15 has an engaging piece 17 and 18 at its free end, which extends from the arm portion by bending at a substantially right angle, and these engaging pieces 17.18 are formed on one side plate 10. And the engaging pieces 17 and 18 are protruded into the drop passage 12 through the arc-shaped groove holes 19 and 20, respectively, and the upper ends 19a and 20a of the arc-shaped groove holes 19 and 20 are formed by the action of the balance weight portion. The carrier arms 13 and 15 are held at predetermined positions to receive coins falling from above.

In the illustrated example, the guide plate 7 for guiding the coins inserted from the coin insertion slot 6 provided on the front plate 5 is placed on the engaging piece 17 of the large-diameter coin carrier arm 13 at the upper position so that the small-diameter coins can be mounted. To prevent large diameter coin carrier
Although the limit lever for 13 is omitted, a limit lever can be provided for the large diameter coin carrier arm 13 as required.

The small-diameter coin limit lever 21 for the small-diameter coin carrier 15 at the lower position is pivotally attached to the outer surface of the other side plate 11 by a pivot pin 22. An engaging piece 23 is provided at the free end of the limit lever 21 for small coins by bending at a right angle, and the engaging piece 23 passes through a window (not shown) formed in the other side plate 11 and enters the coin drop passage 12. Like the engaging piece 18 of the free end of the carrier arm 15 which is projected, the engaging piece of the small diameter carrier arm 14 is engaged with the end edge of the window as shown in the drawing.
It is held in the upper position of 18.

24 and 25 are fixed fulcrum pieces fixed to the passage side surface of one of the side plates 10, and are upper arc portions 24 concentric with the pivot pins 14 and 16, respectively.
It has a, 25a and lower cutouts 24b, 25b.

With the above-described configuration, the large-diameter positive coin A inserted from the coin insertion slot 6 is a carrier coin for large-diameter coins.
The engaging piece 17 of 13 and the upper arc portion 24a of the fixed fulcrum piece 24 are engaged with each other to ride on the carrier arm 13 and rotate the carrier arm 13 so that the upper end of the large diameter regular coin A is fixed as shown by a chain line. It passes under the lower cutout portion 24b of the fulcrum piece 24 and passes through to the true coin receiving side.

The small diameter positive coin B is a carrier coin for large diameter coins 13
Without engaging with the engaging piece 17 and the fixed fulcrum piece 24, it passes through between them and falls, and the limit lever for the small diameter coin.
After hitting the hooking piece 23 of 21, the hooking piece 23 is retracted to the position indicated by the imaginary line 23c, and then the hooking piece 18 of the small diameter coin carrier arm 15 and the upper arc-shaped portion 25a of the fixed fulcrum piece 25 at the lower position. The small diameter coin carrier arm 15 is engaged with the small diameter coin carrier arm 15 and is rotated, and the upper end of the small diameter coin coin B is fixed to the fixed fulcrum piece 25 as shown by a chain line.
It passes under the lower cutout portion 25b and passes to the positive coin receiving side. Therefore, when the small-diameter regular coin B is inserted, the large-diameter coin carrier arm 13 is held in the regular position without rotating.

On the other hand, when an illegal coin C having a smaller diameter than the small regular coin B is inserted, the small illegal coin C is usually provided between the engaging pieces 17 and 18 of the carrier arms 13 and 15 and the fixed fulcrum pieces 24 and 25. After passing through, it falls and is returned as shown by arrow c.

Further, when an illegal coin D having a diameter larger than that of the large-diameter regular coin A and capable of passing through the coin insertion slot 6 is inserted, the large-diameter illegal coin D is associated with the large-diameter coin carrier arm 13. Engage the joint piece 17 and the fixed fulcrum piece 24, rotate the large-diameter coin carrier arm 13 downward and drop it, hit the engaging piece 23 of the small-diameter coin limit lever 21, and draw the engaging piece 23 on an imaginary line 23D. Retract to the position shown, and then
The small diameter coin carrier 15 is rotated downward and dropped as shown by arrow d to be returned.

Further, an intermediate-diameter false coin having a diameter intermediate between the large-diameter regular coin A and the small-diameter regular coin B slips between the engagement piece 17 and the fixed fulcrum piece 24 of the large-diameter coin carrier arm 13. And falls, and the engaging piece 23 of the limit lever 21 for small diameter coins
When hitting, the engaging piece 23 is retracted to the intermediate position between the position 23C and the position 24D, and further, the carrier arm for the small diameter coin.
15 is rotated downward, and like the large-diameter illegal coin D, it is dropped and returned as shown by arrow d.

As is clear from the above description, the engaging piece 23 of the limit lever 21 for the small diameter coin shown in FIG. 5 needs to be retracted to the position 23D in order to allow the large illegal coin D to fall. However, as a result of the engaging piece 23 retracting to the position 23D, the small diameter coin C engages with the engaging piece 18 of the small diameter coin carrier arm 15 as shown by an imaginary line C'in FIG. There is a problem in that the small-diameter coin limit lever 21 is meaningless because it is rotated to pass through the receiving side as shown by the arrow b.

The purpose of the present invention is to solve such a problem, and when engaging with a large-diameter illegal coin D, a limit lever for a small-diameter coin is used.
Although the engaging piece 23 of 21 can be retracted to the position of 23D, when engaging with the small-sized positive coin B or the small-diameter illegal coin C, the engaging piece 23 is retracted only to the position of 23C. It is intended to provide a device.

(Means for Solving Problems) The type II coin sorting device according to the present invention is as follows.

That is, the coin drop passage 12 is formed between the two side plates 10 and 11 which are separated in parallel, and the large diameter carrier arm 13 is pivotally attached to the outer surface of one side plate 10 at the upper position by the pivot pin 14. A small-diameter carrier arm is pivotally mounted on the same side plate 10 in a lower position by means of a pivot pin 16, and both carrier arms 1
Engaging pieces 17, 18 extending substantially at right angles from the arm portion are provided at the free ends of 3, 15, and a balance weight is provided at the other ends, and these engaging pieces 17, 18 are provided on one side plate. The small-diameter coin limit lever 21 of the small-diameter coin carrier arm 15 at the lower position, which is protruded into the coin drop passage 12 through the arcuate groove holes 19 and 20 formed in the 10, forms the pivot pin 22 on the other side plate 11. The small-diameter coin hitting the engaging piece 23 is pivotally attached by the engaging piece 23 provided at the free end of the small-diameter coin limit lever 21 through the window formed on the other side plate 11 into the coin drop passage 12. It is projected at a position above the engaging piece 18 of the small diameter coin carrier arm 14 so that it can be engaged,
The small-diameter coin limit lever 21 is provided with a rotation limiting piece 26, and when the rotation limiting piece 26 rotates, the rotation limiting piece 26 hits the engaging piece 17 of the large-diameter coin carrier arm 13 so that the rotation is limited. It is characterized in that it protrudes into the coin drop passage 12 through a window formed in the other side plate 11 below the engagement piece 17.

(Operation) According to the present invention, the limit lever 21 for small coins is provided with the rotation limiting piece 26 projecting below the engaging piece 17 of the carrier coin 13 for large coins, as shown in FIG. As described above, the small-sized illegal coin C is a carrier coin for large-sized coins.
It passes through between the engaging piece 17 of 13 and the fixed fulcrum piece 24. Therefore, the large diameter coin carrier arm 13 is still held at the position shown by the broken line, so that the small diameter illegal coin C hits the engaging piece 23 of the small diameter coin limit lever 21 and the limit lever 21 of the pivot pin 22 thereof. Limit piece 26 on limit lever 21 as it is rotated clockwise upwards

On the other hand, when a large-diameter illegal coin D is inserted, the large-diameter illegal coin D becomes a large-diameter coin carrier arm.
Push down 13 to the position of virtual line 13D. As a result, the engagement piece 17 of the large diameter coin carrier arm 13 does not exist above the restriction piece 26 provided on the small diameter coin limit lever 21. Therefore, the limit lever 21 for small diameter coins
The engaging piece 23 of can be retracted to the position shown by the virtual line 23D.

With the above, as shown in FIG.
Can rotate the small-diameter coin carrier arm 15 at the lower position and drop it into the return passage.

Also, the intermediate-diameter illegal coin can be dropped into the return passage in the same manner as the large-diameter illegal coin D by retracting the engaging piece 23 of the limit lever 21 for the small-diameter coin to the position 23C. When the coin is dropped, it can be returned by opening the coin drop passage 12 with a return lever (not shown).

As described above, according to the present invention, the limit lever for small-diameter coins can be reliably actuated, so that coin diameters can be reliably sorted by the two carrier arms.
