DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin changer used for a vending machine (hereinafter referred to as a vending machine).

[0002]

2. Description of the Related Art A conventional coin changer will be described below.

As shown in FIG. 8, a conventional coin changer requires a check block A for sorting coins inserted into a vending machine and sorting the coins by denomination, and a tube block B for stacking and storing the sorted coins by denomination. It is composed of three blocks, that is, a dispensing block C for dispensing an appropriate amount of change from the tube.

[0004] Generally, vending machines are often installed outdoors, so that the operating environment of a coin changer mounted on the vending machine is extremely severe as inferred from temperature conditions and weather conditions such as dust and rain.

[0005] Further, since it is an unattended sale, there are many misuses and mischiefs. If it enters through the slot, not only coins but also liquids will all enter the coin changer. Under such extremely severe use environment, it is natural to ensure basic performance and quality in a coin changer, but on the other hand, when coins are clogged in the coin changer for the above reasons. How quickly it can be treated is a major factor required of coin changers in the actual market.

[0006] For the above reasons, the conventional coin changer has a check block A, a tube block B,
The payout block C is composed of three blocks.

Here, a description will be given of a conventional method of treating a coin changer when an abnormality such as a jam occurs in a series of operations from receiving a coin to paying out a change.

First, as a phenomenon of coin clogging generally occurring in the check block A, as shown in FIG. 9, when the inserted coin 18a stagnates at the coin receiving port 17, when the next inserted coin is stagnated. 18b, 18c..., And coins do not flow into the passage 19, and coins are caught and jammed in the gate 20 because the coin movement and the gate operation timing do not match in the denomination sorting gate unit 20.

When these clogging phenomena occur during use, it is possible to operate the return lever usually near the coin slot of the vending machine. Then, by this operation, the return arm 21 of the coin changer moves in the direction of the arrow in conjunction with the return lever, and the opening / closing plate 22 constituting the passage opens in the direction of the arrow E to remove the jammed coins and return them. Will return to your mouth.

[0010] However, if the jammed coins are still unresolved, the door of the vending machine is opened to remove the jammed coins directly from the coin changer. At this time, instead of removing the coin changer from the vending machine and working, the necessary check block A can be taken out and treated.

Next, as an example of coin clogging in the tube block B, there is a case where the coins 15 are not stacked in the tube 14 as shown in FIG.

In such a case, only the tube block B is taken out from the coin changer, and the coins can be processed into a normal stacked state.

Further, the dispensing block C generally has a structure as shown in FIG.
In order to pay out the lowermost coin 15a among the coins 15 stacked in the inside, the slide plate 12 is moved as shown in FIG.
1 (a), FIG. 11 (b), and FIG. 11 (a). At this time, the timing of the movement of the coin and the operation of the slide plate 12 may be abnormal due to the deformation or dirt of the coin, the strain of the structural component, or the like, and the coin may be jammed. The state is the slide plate 1 as represented in FIG.
2 is a state in which a coin is bitten.

In this case, as shown in FIG. 13, a guide 26 for guiding to the return port 25 of the vending machine is provided immediately below the coin payout port 24 of the coin changer 23, so that the payout block C remains attached to the coin changer. It is impossible to remove. For this reason, it is necessary to remove the screw 27, remove the coin changer 23 from the vending machine once to make it stand alone, and then remove the payout block C to remove the jammed coins.

[0015]

As is apparent from the above description, in the conventional configuration, when an abnormal condition such as a jam in a coin occurs in a coin changer, the check block A is used.
In the tube block B, it is possible to perform a treatment operation with the coin changer attached to the vending machine, but only for the blockage of the payout block C, the treatment operation cannot be performed unless the coin changer is removed from the vending machine. was there.

The present invention solves such a problem. Even if a coin is jammed in the payout block C, the coin changer is not removed from the vending machine.
It is another object of the present invention to provide a coin changer capable of removing jammed coins without removing the payout block C from the coin changer.

[0017]

In order to achieve the above object, a coin changer according to the present invention has a structure in which a rotating knob is connected to a gear of a speed reduction mechanism constituting a payout block.

[0018]

According to this configuration, when the coin is jammed by the slide plate during the payout operation, the coin is jammed by manually rotating the rotary knob from the outside with the coin changer attached. Since the slide plate in the state can be moved in the direction opposite to the payout operation (the direction in which the jammed coins are released), the jammed coins can be easily removed.

Therefore, jammed coins can be removed without removing the payout block from the coin changer.

[0020]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows a configuration of a coin changer. The coin changer selects a coin and sorts the coins according to denominations, a tube block B for stacking the sorted coins according to denominations, and a required amount of money. It consists of three blocks, a dispensing block C for dispensing change from the tube. Next, FIG. 1 is a diagram in which a rotation knob 13 is provided using a speed reduction mechanism of a coin changer. FIGS. 3, 4, and 5 are views showing the payout from the tube 14, and FIGS. 6 and 7 are views showing the position of the rotary knob 13 in the coin changer.

The coin changer according to the present invention includes a check block A for sorting coins inserted from an insertion slot into genuine coins, counterfeit coins, denominations, and the like, and a coin provided below the check block. The payout block C is constituted by a coin changer comprising a tube block B for sequentially storing coins for each type and a payout block C provided below the tube block and paying out coins in the tube block. A slide plate 12 for paying out coins interlocked with the reduction gears 2 to 7 and a rotation knob 13 connected to the gears 2 to 7 are provided. The rotation knob 13 is provided on the outer wall of the coin changer or in the tube block storage unit. It is characterized by being arranged on a wall surface.

Here, the payout block will be described in more detail. In FIG. 1, reference numeral 1 denotes a payout drive motor, which performs predetermined reduction by reduction gears 2 to 7, and transmits the same to cranks 9 and 10 via reduction gear 7 and gear 8. The rotational force transmitted from the drive motor 1 at a reduced speed is transmitted from the gear 8 to the cranks 9 and 10, where the slider 11
Is converted into a reciprocating linear motion (arrow B motion). Furthermore,
The slider 11 has a slide plate 12 (12a to 12a).
The slide plate 12 arbitrarily connected to any one of e) (not shown) performs a reciprocating motion integrally with the slider 11.
As a result of this reciprocating movement, the slide plate 12 pulls out the lowermost coin 15a of the coin 15 in the tube 14 formed above as shown in FIG. 3, and when it reaches a predetermined moving position, lowers the coin 15a (return port). ). Here, if the coin 15 is deformed or stained, or a structural component is distorted, as shown in FIG. 4, the coin 15a does not drop even when the backward movement operation (arrow B operation) of the slide plate 12 starts, and the coin 15 is jammed. It may be in a state (coin jam). In this case, the coin changer stops and stops, so it is necessary to remove the jammed coins.

At this time, according to the present invention, as shown in FIGS. 1 and 6, the rotary knob 13 can be manually turned from the outside only by removing the tube block B. Therefore, as shown in FIG. Is moved in the direction of arrow C, and coin 1
5a. That is, the rotary knob 13
By operating, the coin 15a is dropped downward (return port) to release the jamming symptom, whereby the function of the coin changer can be returned to normal.

When the rotary knob 13 is operated, the rotational force is light, and the size of the rotary knob 13 and the reduction gears 2 to 7 to be connected are selected so that the coins can be removed in about one rotation. . A non-slip shape is also provided so that a finger does not slip when operating the rotation knob 13.

In this embodiment, as shown in FIG. 6, the rotation knob 13 is provided on the wall surface 16 in the tube block housing. However, as shown in FIG.
Alternatively, although not shown, it may be arranged at any place on the outer wall of the coin changer.

[0026]

As described above, according to the coin changer of the present invention, the rotation knob connected to the reduction gear is arranged so as to be able to be operated from the outside. Even so, the coin can be removed by turning the rotary knob from the outside while the coin changer is attached to the vending machine,
Eliminates the need to remove coins by removing the coin changer as in the past, so that ordinary people who do not have specialized knowledge (for example, people who install vending machines) can easily and quickly take measures. Will be able to
