Description

DETAILED DESCRIPTION OF THE INVENTION This invention detects abnormalities in perforated coins in a coin sorting machine in which coins are conveyed by a tilted and rotating movable disk and guided to a sorting drum, and sorted and counted by this sorting drum. The present invention relates to a detection device configured as described above.

Conventionally, as an example of a coin sorting machine,
8389 has been proposed. In this coin sorting machine, coins are stored one by one in a large number of pockets formed on the outer periphery of a rotating movable disk.
The coins were guided into the sorting shelf through the drop opening, and the sorting grooves in the sorting shelf sorted the coins to have a diameter corresponding to the width of the groove, which was then counted.

However, while this sorting means has the advantage of being able to quickly sort coins, it also detects the diameter of the coin, so it may not be possible for the edges of the coin to be damaged and partially protrude or dented. Then, there was a risk that the coins would be confused with different types of coins that are similar in size. For example, domestic coins are arranged in descending order of diameter, each with an old 50
Yen coins are 25.0mm, 10 Yen coins are 23.5 mm, 100 Yen coins are 22.6 mm, 5 Yen coins are 22.0 mm, and 50 Yen coins are 21.0 mm.
mm, 1 yen coin is 20.0 mm, but 100 yen coin and 5
0.6mm for yen coins, and 1.0 for 50 yen coins and 1 yen coins.
If the edges of the 5 yen coin and 1 yen coin, which have a size difference of only mm and are made of relatively soft material, are crushed and partially enlarged, there is a possibility that they will be mistakenly sorted as 100 yen coin and 50 yen coin, respectively. Ta.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to enable reliable sorting of coins by intensively detecting holes in coins having holes.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

are formed with some spacing in the rotational direction of the main shaft 5, and a damaged coin detection hole 32 is formed on the side (above the coin outlet 31a to 31f) corresponding to the through hole 24 of the sorting shelf 20. This damaged currency detection hole 32 is formed.
A light projector 33 that irradiates the detection hole 32 with light is provided on the bearing at a position that simultaneously faces the through hole 24 passing through the detection hole 32, and the cover 9 has a detection hole 24 sandwiching the through hole 24. 9 light receiving elements 34a that face the inside of 32 and detect the light of the projector 33
A detecting section 35 having .about.34i is provided.
As shown in FIG. 5, these light receiving elements 34a to 34i are arranged in three pieces each along the moving direction of the sorting shelf 20, and at least the central three light receiving elements 34a to 34c are It faces the through hole 24.

Further, the detection insertion grooves 30a to 30 of the cover 9
A detection piece (not shown) is inserted into f for detecting the presence or absence of coins and counting them by denomination of coins,
Coins supported on each of the coin shelves 23a to 23f are taken out by denomination to the coin outlets 31a to 31f below, respectively.
A scraping member (not shown) is provided, which is known in the art, and will not be described here.

Furthermore, a chute 36 is a chute for guiding the coins taken out from the coin ejecting ports 31a to 31f according to their denominations. A device (not shown) for temporarily holding or sorting coins is provided.

Note that the damaged currency detection hole 32 and the like are provided above a detection piece for counting, which is not shown.

Moreover, the one shown in FIG. 6 has nine light receiving elements 34.
This is an example of the detection circuit when using a to 34i, in which the three upper light receiving elements 34d to 34f arranged in the coin movement direction are connected to the upper discriminator 40, and the three middle light receiving elements are connected to the upper discriminator 40. 34a to 34c are connected to the central discriminator 41, and the lower three light receiving elements 3
4g to 34i are connected to a lower discriminator 42, and each of these discriminators 40 to 42 is connected to an alarm signal terminal 45 via an OR gate 43 and a flip-flop circuit 44, and a reset signal terminal 46 is connected to the flip-flop circuit 44. A signal is now being input. To explain the central discrimination section 41, for example, when an abnormal 5 yen coin A covers the detection section 35 and only the light receiving element 34b detects light, an output signal is output to the alarm signal terminal 45, and other upper and lower column discrimination The sections 40 and 42 are also adapted to output signals under similar conditions.

The operation of one embodiment configured in this way will be described below.

When a large number of coins of mixed denominations are supplied to the hopper 14 while the drum 6 is rotating, the pocket 8 of the movable disk 7 guides the coins one by one to the drop opening 11 of the receiving plate 10, and the coins are transferred to the coin guide. 13 to the sorting shelf 20. The coins sent one by one to each sorting shelf 20 are separated by a cover 9 and a sorting groove 2.
1, and is supported by one of the coin shelves 23a to 23f corresponding to the diameter of the coin, and is counted by each denomination by the detection piece inserted into the detection piece insertion groove 30a to 30f. The cover 9 is removed from each coin outlet 31a to 31f by a scraping member.
The shoot 3 is taken out to the outside of the
Collected by 6.

On the other hand, in the embodiment shown in FIGS. 3 and 4,
Scraping groove 2 corresponding to 100 yen coins on sorting shelf 20
A detection unit 35 is provided at 2c. Therefore, the following determination is made regarding the through holes 24 of each sorting shelf 20 that pass through the detection section 35.

(a) When a coin passes through the detection unit 35 without being supported on the 100 yen coin shelf 23c of the sorting shelf 20, each of the light receiving elements 34a to 3 of the constant detection unit 35
The light from the projector 33 emitted toward the light source 4i sequentially irradiates each of the light receiving elements 34a to 34i of the detection unit 35 as it passes through the through hole 24, and all the light receiving elements 34a to 34i are irradiated. After that, the irradiation is sequentially canceled. In each of these states, the detection circuit shown in FIG. 6 does not detect any abnormality. That is, the three light receiving elements 34 in the center of FIG.
For a to 34c, "34a", "34a,
34b", "34a, 34b, 34c", "34
The light is irradiated in the order of ``b, 34c'' and ``34c'', and no abnormality signal is generated from the central discrimination section 41.

(b) A regular 100 yen coin is placed on the 100 yen coin shelf 23c of the sorting shelf 20.
When a yen coin is supported and passes through the detection section 35, the 100 yen coin always closes the through hole 24, so the detection section 35 does not operate, and therefore an abnormal signal is generated. will not be performed.

(c) An abnormal 5 yen coin (perforated coin) A corresponding to the size is placed on the 100 yen coin shelf 23c of the sorting shelf 20.
When the abnormal 5 yen coin A is supported and passes through the detection unit 35, the light from the projector 33 sequentially illuminates, for example, the central three of the light receiving elements 34a to 34i one by one as the abnormal 5 yen coin A passes. . That is, the light receiving elements 34a, 34b, and 34c are irradiated in this order.
As described above, when the state shown by the chain line in FIG. 6 is reached, the central discrimination section 41 detects an abnormality and a signal is output from the alarm terminal 45. Moreover, when the hole of the abnormal 5 yen coin A is slightly shifted in the vertical direction and is supported on the 100 yen coin shelf 23c, and the light from the projector 33 illuminates each of the light receiving elements 34d to 34i arranged at the top and bottom in FIG. The upper and lower stage discriminators 40 and 42 will detect an abnormality.

Next, we will explain what to do when a signal is output from the alarm signal terminal 45. In response to this signal, an alarm such as a lamp display and a buzzer is issued, and the sorting shelf 20 on which the abnormal 5 yen coin A is supported is removed. A scraping member is inserted into the groove 22c, and the abnormal 5 yen coin A is taken out from the coin outlet 31c and separated from normal coins in the chute 36 or the like.

Further, when an alarm signal is output, the coins of the corresponding denomination are removed from the coin count, and the device is also stopped as necessary.

Next, when the abnormal 5 yen coin A is removed or inspected and then reset, the reset button is operated. , the reset button may be operated using this extraction operation.

In addition, in the above embodiment, the sorting shelf 20
Abnormality 5 by forming a through hole 24 in the 100 yen coin shelf 23c
Although it was detected whether the yen coin A was supported, that is, the presence or absence of a hole in the coin supported on the 100 yen coin shelf 23c, the present invention is not limited to this embodiment. Through hole 2 similar to
4, the presence or absence of a hole in the supported coin is detected using the detection means shown in FIG. design changes are possible.

As explained above, the device of the present invention guides coins dropped from a pocket into the sorting groove of the sorting shelf and supports the coins at a position with a groove width corresponding to the diameter of the coin, thereby removing the gold of the coins. In addition to discriminating the species, the light emitter and at least three light-receiving elements arranged at intervals in the groove direction of the sorting groove are made to face each other through the through hole in the bottom of the sorting groove. It is possible to detect a coin depending on the presence or absence of the coin, and the light-receiving element detects the hole in the coin when one of the three center elements is receiving light and the other two are not receiving light. Therefore, by double-checking the denomination of the coin using the sorting groove and the presence or absence of holes, it is possible to focus on detecting holes in coins that have holes or detecting the absence of holes in coins. Therefore, even if the edges of the coins are deformed, missorting can be reduced.
Reliable selection is possible.
