Description

[Detailed Description of the Invention] This invention relates to a coin handling device in an automatic fare box such as a one-man bus, which has a single coin slot for flat fares.

Conventional fare boxes have 20 coin slots, one slot that does not require change, and one slot for high-value coins that requires change. is using a method of visual confirmation.

In addition, the amount of money put into the slot for high-value coins that requires change is automatically counted and the change is dispensed.

Passengers are often confused by the fact that there are 20 slots, and if a coin is inserted into the wrong slot, the driver must visually check the coins, operate the return button, and then insert the coins into the correct slot again. There must be.

The same applies if counterfeit coins are inserted, and must be returned based on visual judgment.

Therefore, when a return is required, there is a drawback that confirmation judgment and operation are troublesome. In order to eliminate these complications, the present invention has a single coin insertion slot and automatically records the inserted amount. aligned to,
Inspect, count, and collect only the amount of the specified fee. If change is required, pay out change. If you accidentally put in extra coins or if counterfeit coins are mixed in with the coins you put in, this is the case. The system automatically detects coins in the fare box and uses the return signal to form a path that guides the coins to the return chute.

Next, the structure of the present invention will be explained with reference to the embodiments shown in FIGS. 1 to 5.

This automatic fare box is provided with a single input port (not shown), beneath which a conveyor belt 1 runs.

A transmission band 2 is placed behind it, and several pawls 3 are planted at equal intervals.

Further, a cam 5 is fixed coaxially to the drive gear 4 that drives the transmission band 2, and rotates at the same time as the drive gear 4.

Since the spacing between the pawls 3 (the number of pieces of the transmission band 2) and the number of teeth on the drive gear 4 are the same, the spacing between the pawls 3 is equal to the feed for one revolution of the drive gear 4. Therefore, the rotation of the cam 5 and the moving position of the claw 3 are synchronized,
They maintain a certain relationship.

The coins 14 inserted through the input port and sent by the conveyor belt 1 are pushed by the claws 3 and pass through the inspection and counting mechanism section 6.

At this time, the coin 14 moves while being pressed against the abutment part 15 of the passage, but this abutment part 15
It is shaped so that it curves outward, imitating the shape that bulges outward.

If the amount of the coin 14 passing through the inspection and counting mechanism section 6 is the amount of the specified fee, the inertial force when the coin 14 stays on the abutting section 15 and moves after leaving the abutting section 15 acts. , No. 11 is guided and stored in storage chute No. 7.

Many methods and mechanisms are known for sorting the coins 14 by the inspection and counting mechanism section 6.

For example, Japanese Patent Publication No. 47-49040 ``Coin Sorting Apparatus'' discloses a device that electrically sorts coins using oscillating circuit sound.

In the present invention, an appropriate one of these known screening methods is used.

When a return signal is issued from the inspection and counting mechanism section 6, the solenoid 8 immediately comes into operation.

In the embodiment shown in FIG. 4, when the solenoid 8 is actuated and sucked to the left, the shifter 9 rotates clockwise, and the return lever 10 that is linked therewith moves from the chain line position to the solid line position. I come to do it.

When the return lever 10 is in the chain line position, the cam 5 simply rotates in the gap 11 and does not affect the return lever 10 at all, but when the return lever 10 moves to the solid line position, the cam 5 In this case, as the cam 5 rotates, the return lever 10 is moved and pushed out against the tension of the spring 12.

For this reason, the coin 14 is struck by the return lever 10 and guided to the return chute 13 from an intermediate portion between the mechanism section 6 and the storage chute 7.

With this structure, the coins 14 inserted into the single input slot are fed by the conveyor belt 1, then inspected one by one by the claws 3 of the transmission band 2, and sent to the needle-like mechanism section 6. .

If the amount of coins 14 passing through this point is the specified amount, the coins 14 are guided as they are and deposited into the storage chute 7, and if change is required, the change is dispensed. If coins are mixed in,
A return signal is issued from the inspection and counting mechanism section 6, which acts on the solenoid 8 to move the return lever 10 interlocked with it.

Therefore, the position of the gap 11 also changes, so the cam 5 hits the return lever 10 and pushes the return lever 10 against the tension of the spring 12.
is moved, and the coin is sent to the return chute 13.

At this time, since the rotation of the cam 50 and the moving position of the pawl 3 are configured to maintain a constant relationship, the return lever 10 moved by the cam 5 and the pawl 3 are in a synchronous relationship, and when the solenoid 8 is activated Even if the return lever 10 is lowered, the lowering timing of the return lever 10 and the position of the claw 3 at that time can be selected at a constant value, so that there is a margin for operation.

As mentioned above, the feature of the present invention is that the return lever is operated in synchronization with the pawl by the cam, so that the coins can be automatically guided to the storage chute or the return chute, and the overall Despite the physically simple structure, there is an effect that the coin sorting process is performed reliably.
