Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a coin sorting device installed in the fare box of a one-man bus.

[Conventional technology]

2. Description of the Related Art Conventionally, a coin sorting device as shown in FIG. 1 has been installed inside a one-man bus fare box or the like.

The structure and operation of this prior art will be briefly explained below with reference to FIG.

This conventional coin sorting device is roughly divided into three sections: a coin feeding mechanism section A, a defective coin ejection mechanism section B, and a coin sorting mechanism section C. Coins pass through these three sections in order. It is something to do.

In this coin sorting device, first, when the rotary plate 5 is rotated by a driving source (not shown), the rotary plate 5
Coins are sent out to the coin receiver 2 one by one through the groove 4. The sent coin comes into contact with the holding rod 12 and is temporarily held on the coin rail 7. Next, as the rotary plate 5 rotates, the coin feeder 11 located on the back surface 6b side of the base plate 6 presses the coin in the advancing direction. The pressed coins are sent out into the gap 21 formed by the base plate 6 and the defective coin discharge plate 22.

At this time, if the coin is a normal coin, it rolls on the discharge plate rail surface 23 and reaches above the normal coin receiving part 41 of the sorting rail plate 43. On the other hand, if the hard coin is bent and defective, it will not be able to pass through the gap 21 and will stop at the entrance of the defective coin discharge plate 22.

Then, in this state, as the rotary plate 5 rotates, the lifting rod 28 lifts the defective coin discharge plate 22. As a result, the lower surface of the gap 21, which was a passage for coins, is opened, and the defective coins fall downward from the opened portion and are ejected. This defective coin discharge plate 22 is connected to the lifting rod 2
8 lowers as the rotating plate 5 rotates,
Return to the original position and repeat this movement at regular intervals.

That is, from the time when the first groove 4 sends a coin to the coin rail 7 to the time when the next groove 4 sends a coin to the coin rail 7, the coin feeder 11 performs the above-mentioned operation, and then at regular intervals. and lifting rod 2
8 performs the same operation as described above.

Next, the normal coin is stored in the normal coin receiving section 41.
From above, the coin sorting mechanism section C is moved by the conveyor belt 47.
transported to. A sorting board 44 is provided in this coin sorting mechanism section C, and between the sorting board 44 and the sorting rail surface 42, coin through holes 46 are formed in order from the smallest to the largest coin to match each type of coin. is forming.

Therefore, among the coins conveyed by the conveyor belt 47, the smallest coin falls into the first coin hole 46, and the next smallest coin falls into the next coin hole 46. The coins are sorted in this way.

[Problem that the invention attempts to solve]

However, a problem arises when the coin passes through the defective coin ejection mechanism section B and reaches the normal coin receiving section 41.

In other words, the coins on this normal passage receiving section 41 should be conveyed into the coin sorting mechanism section C by the conveyor belt 47, but coins with worn out surface irregularities or with rounded corners Since coins or coins that have oil or the like on their surfaces are slippery, they often do not get caught on the conveyor belt 47 and therefore remain on the normal coin receiving section 41 without being conveyed.

In this case, the next normal coin sent hits the previous coin and stops on the discharge plate rail surface 23. Therefore, when the lifting rod 28 lifts the defective coin discharge plate 22, these normal coins fall and are discharged as defective coins.

[Means for solving problems]

The present invention has been devised to solve the above problems. The configuration will be explained below.

The coin sorting device according to the present invention is composed of a coin feeding mechanism section A, a defective coin discharging mechanism section B, and a coin sorting mechanism section C.

The coin dispensing mechanism section A uses a plurality of concave grooves 4 provided on the circumferential edge of the inclined upper surface of the rotary plate 5 to dispense the coins 3.
is configured to send the coins to the coin receiver 2 one by one.

The defective coin ejecting mechanism section B forms a gap 21 with a base plate 6 provided parallel to the upper surface of the rotary plate 5, which is large enough for only normal coins 3 to pass through, and also prevents the normal coins 3 from rolling down. The defective coin ejection plate 22 forming the ejection plate rail surface 23 which is a road surface and the rotation of the rotary plate 5 are linked to lift the defective coin ejection plate 22 from above the board 6.
and a lifting rod 28 that eliminates the passage for the coins 3 that was formed between the coin discharge plate 22 and drops and discharges the defective coins that are blocked from passing through the gap 21. .

The coin sorting mechanism section C includes the defective coin ejection plate 22.
The normal coins 3 falling on the ejection plate rail surface 23 are transferred to the normal coin receiving part 4 of the sorting rail plate 43.
1, and the coins 3 located on the normal coin receiving part 41 are conveyed by a conveyor belt 47 to a main part configured to be sorted according to their diameters with reference to the sorting rail surface 42 of the sorting rail plate 43. It is configured as follows.

A guide rail distance a that connects the outlet end of the discharge plate rail surface 23 of the defective coin discharge plate 22 and the normal coin receiving section 41 located below the outlet end and that can hold the coins 3 is provided. It is characterized in that it is provided with a guide 101 having the following characteristics.

[Effect]

The operation of the coin sorting device of the present invention with the above configuration is as follows:
This will be explained below.

The present invention is different from the prior art except for the provision of the guide 101, which is a feature of the present invention, so the effects caused by the provision of the guide 101 will be explained here.

In the coin sorting device of the present invention, if the corners are removed or
When a coin that has become slippery due to adhesion of oil, etc. does not catch on the conveyor belt 47 and remains on the normal coin receiving section 41, the next coin sent out hits the previous coin and slips into the guide. It will be located on 101. Therefore, even if the lifting rod 28 lifts the defective coin ejection plate 22, the coins are not ejected because they are not located on the ejection plate rail surface 23 as in the conventional case.

As shown in FIG. 5, the coin 3' that is not caught on the conveyor belt 47 and remains on the normal coin receiving section 41 is collided with the coin 3'' that is sent out next, and due to the force of this collision. The hard material 3' is then pushed toward the conveyor belt 47. As a result, the hard material 3' is caught on the conveyor belt 47 and conveyed.

Coin 3' stuck on the normal coin receiving part 41
The coin 3'' that collided with the coin 3'' is transported to the coin sorting mechanism section C at the same time as the stopped coin 3'.
According to the inclination of the guide 101, the coin rolls down to the normal coin receiving part 41 due to its own weight and is located there.

In this way, the coin 3'' that has rolled down to the normal coin receiving section 41 is conveyed by the conveyor belt 47, or if it is slippery, it is fed next time in the same way as the coin 3' described above. The coins are pushed by the incoming coins and conveyed by the conveyor belt 47.

Therefore, among normal coins, even coins that are heavily worn and coins that are slippery due to oil or the like adhering to their surfaces are reliably conveyed to the coin sorting mechanism section C.

〔Example〕

An embodiment of the present invention will be described below.

The structure of the coin feeding mechanism section A is as follows.

A coin receiver 2 is fixed to the rotary plate support frame 1, and a rotary plate 5 is provided with a plurality of grooves 4 on the circumferential edge of its upper surface in order to feed coins 3 one by one.

The groove 4 has an inclination that is large enough to hold a coin. The depth of this groove 4 is set to approximately half the wall thickness of the coin, and is lowered by the rotation of the rotary plate 5, so that the part of the coin exposed from the groove 4 hits the coin receiver 2. , the coin is taken out from inside the groove 4 and rolls down on the coin rail surface 8.

Therefore, the groove 4, the coin receiver 2, and the coin rail surface 8 have an inclination that enables the above-mentioned function.

When the coin rolls on the coin rail surface 8, a steel wire 9 is stretched on the substrate 6 in parallel with the coin rail surface 8 so that the coin can easily roll.

A long through hole 10 is provided on the steel wire side of the substrate 6, and a coin feeder 11 reciprocates through this long through hole 10. As shown in the enlarged cross-sectional view of FIG.
As the rotary plate 5 rotates, it protrudes onto the top surface 6a of the substrate 6 and the top surface 6b of the substrate 6
After moving parallel to a, the terminal end 10 of the long through hole 10
It is set to move in a parallelogram trajectory, drawing toward the rear surface 6b and returning to the original position with b as the limit.

This coin feed 11 is interlocked with the rotary plate 5 by a cam and a link mechanism, and draws the above-described constant trajectory.

The holding rod 12 that temporarily holds the coin 3 is inserted into the circular arc through hole 1 provided in the upper part of the long through hole 10 of the base plate 6.
3 and is supported by a spring provided on the back side 6b of the base plate 6 so as to be located at the lower end 13a of the arcuate hole 13 with a light force sufficient to hold the coin 3.

The gap 21 of the defective coin ejection mechanism section B is formed by bending the lower end of the defective coin ejection plate 22, as shown in FIG.

The defective coin discharge plate 22 is supported by a fixture 24 fixed to the base plate 6 via a shaft 25. One end of the coil spring 26 supported by the shaft 25 contacts the side surface 24' of the fixture 24, and the other end presses against the outer surface 22a of the defective coin discharge plate 22.

The lifting rod 28 protrudes from a through hole 27 formed in the substrate 6.

At the lowest position, the lifting rod 28 has an upper end surface in contact with the inner surface 22b of the defective coin ejection plate 22, and protrudes as the rotary plate 5 rotates.
After lifting 2, return to the original position.

In order to reliably convey the coins, the conveyor belt is a so-called ridged conveyor belt 47 with unevenness formed on its surface.

An auxiliary wheel 49 is provided adjacent to a belt pulley 48 that operates the conveyor belt 47, and the shafts of the belt pulley 48 and the auxiliary wheel 49 are supported by springs (not shown) and swing. 47 and the substrate 6, a gap suitable for conveying coins is always formed.

The guide 101 is provided by cutting out the exit side of the ejecting plate rail surface 23 of the defective coin ejecting plate 22, and connecting the ejecting plate rail surface 23 and the normal coin receiving section 41 located below it to the notched part. We have set this up as much as possible.

This guide 101 has a straight downward slope on its upper surface in order to smooth the rolling of coins between the discharge plate rail surface 23 and the normal coin receiving section 23.

Note that the rail distance b of the discharge plate rail surface 23 after the cutout is set to a value larger than the diameter of the largest coin to be sorted.

[Effect of idea]

As described above, since the present invention is provided with a guide, when a coin is stopped on the normal coin receiving part, the next coin to be sent out will be located on the guide 101. Therefore, it will not be discharged by mistake.

Further, the coins that are not caught on the conveyor belt but are located on the normal coin receiving section are pushed by the next coin and hooked on the conveyor belt, and are surely sent into the coin sorting mechanism section.
