[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic coin return mechanism for a manual vending machine.

[0002]

2. Description of the Related Art Conventional vending machines that are installed indoors or outdoors for the automatic sale of various products are generally stationary and large in size, so that they can be used for a long time by voluntarily replenishing various brands of products. It is usually configured.

[0003]

As described above, the vending machine, which is stationary and can be replenished with products of various brands, is generally used for a long period of time. Therefore, it is required to have durability as well as to store as many products as possible to lengthen the replenishment cycle, resulting in a large size. Debu,
It is usually expensive and heavy because it has to be designed to have sufficient durability up to internal devices such as the public inspection department. Further, in this type of vending machine, the internal storage section, the product ejection section, and the like are exposed at the time of replenishment of the product and the product is arbitrarily touched, which causes a failure. Therefore, maintenance is essential. Then, in addition to the trouble of replenishing the products, the trouble and cost for this maintenance must be borne by the side that purchases and manages the vending machine.

In addition, when the management side replenishes the vending machine with products in this way, the management side may pack similar products of other companies in place of designated products, and a person other than the manager There is a possibility that the customer may misunderstand that the product storage section is touched, and the product provider may not be able to maintain the originality and credibility of its product. Therefore, contrary to the conventional wisdom of the conventional vending machine that is a fixed type and replenishment of products on the management side, depending on the product, it is sold automatically in a place where it can be monitored indoors and where there is no fear of theft. Machines may be installed, and
For convenience of management, it is more convenient if it can be moved and used appropriately. For such products, the vending machine does not require so much durability, but rather, it is lightweight, simple and inexpensive. Paying attention to the case that the product fits the needs, and if the products are packed at the beginning and shipped together with the vending machine, the burden of replenishment and maintenance on the manager side is eliminated, and the originality and credit of the product are eliminated. Based on the idea that it will be possible to hold the product, we have proposed a method of original filling of vending products that realizes this and a vending machine of single-use vending machine for that purpose.

The original packing method of the above-mentioned vending product proposed by the inventor of the present invention is such that the product is stored in the product storage portion inside the housing at the time of assembling the housing of the vending machine, and the product is not refillable at the shipping destination. The product is to be refilled only when the vending machine is collected after the product is sold out.
A frame of the vending machine is composed of a frame and an outer case having a product outlet, and a coin inspection unit for inspecting inserted coins inside the case and a coin that has been inspected. And a merchandise storage unit for storing merchandise in a predetermined arrangement, and taking out merchandise from the merchandise storage section on condition that the coins inspected by the coin coin inspection section have reached a predetermined amount. A product ejecting unit for ejecting to the mouth is provided, and the outer case is assembled by a sealing means on the assumption that the housing is not opened after a predetermined quantity of products is stored in the product storing section when the case is assembled. Only the metal box can be taken out even when the outer case is assembled.

[0006] By the way, in the above-mentioned vending machine for filling goods, it is possible to apply the mechanism of a conventional stationary vending machine to the mechanism for ejecting a product, but this kind of automatic vending machine can be applied. In the case of a machine, since it deals with a single brand of product and is a small-sized vending machine that is used up, it is desirable to use a product dispensing mechanism that can manually operate the dispensing lever. Even if it is a cheap type of vending machine, it is not that the coins are not returned properly when inserting coins more than the setting as is often the case,
It is necessary to provide a mechanism to automatically return the excess when the amount of money received exceeds the set amount. Further, such a coin automatic return mechanism can be used not only as a product vending machine but also as a return mechanism for a normal automatic vending machine that manually ejects a product.

It is an object of the present invention to provide a coin automatic return mechanism having a simple structure capable of automatically returning coins of a set amount or more in a manual vending machine.

[0008]

Until only five hundred-yen coins 43 are inserted, the downward movement of the ejection lever 25 is regulated halfway by the restriction piece portion 48b of the stopper 48, and five hundred-yen coins 43 are inserted, and they are accumulated and held. Then, the stopper 48 is rotated to the position shown by the chain double-dashed line in FIG. 9 by pushing the detection piece 48a, and the restriction by the restriction piece 48b is released. Also, when one 500-yen coin 46 is inserted and held at the entrance of the accumulating and holding unit, the detection piece unit 4 also remains.
8a is pushed, the stopper 48 rotates to the position shown by the chain double-dashed line in FIG. 9, and the regulation by the regulating piece 48b is released. However, when even one hundred-yen coin 43 is already held in the stacking holding part when one hundred-hundred-yen coin 46 is inserted, the mixing prevention stopper 50 collects the genuine gold passage 41 as described later. A predetermined distance from the entrance of the holding portion is squeezed to prevent the passage of the 500-yen coin 46.

If five hundred-yen coins 43 are inserted, or one five-hundred-yen coin 46 is inserted and the detection piece 48a is pushed and the stopper 48 is rotated to the position shown by the chain double-dashed line in FIG. When the portion 48d projects into the genuine gold passage 41 and further one hundred yen coins 43 or five hundred yen coins 46 are inserted in this state, those coins 43 or 46 are guided to the return passage 42 by the guide portion 48d, and the return port You are led to 11.

In the coin inspection unit 2 of this vending machine, when the 500-yen coin 46 is inserted in the state where even one 100-yen coin 43 is inserted in the stacking holding section, the 500-yen coin 46 is inserted. A mixing prevention stopper 50 is provided to prevent entry into the holding position at the entrance of the stack holding unit. The mixing prevention stopper 50 is swingably supported in the vertical plane with the center as a fulcrum, and can project to a position where it interferes with the one hundred-yen coin 43 held at the bottom of the stack holding unit. And a 500-yen coin 4 with a simple detection piece 50a provided at the lower end.
A restricting piece 50b is provided at the upper end so that it can project so as to narrow the genuine metal passage 41 by a predetermined width above the entrance position for holding 6, and the detecting piece 50a is normally in the projecting position and the restricting piece 50b retracts. The center of gravity is set to the position.

When the first 100-yen coin 43 is inserted, the detection piece 5
When 0a is pressed, the mixing prevention stopper 50 rotates to the position shown by the alternate long and short dash line in FIG.
Protrudes and blocks the passage of the 500-yen coin 46. At this time, the protruding amount of the restriction piece portion 50b is set so as to prevent the passage of the 500-yen coin 46 but to pass the 100-yen coin 43.
Therefore, when only the hundred-yen coins 43 are continuously inserted, the hundred-yen coins 43 are allowed to pass through without any trouble. Then, when the 500-yen coin 46 is inserted in a state where even one 100-yen coin 43 is inserted in the stacking and holding unit, the 500-yen coin is stopped above the holding position.

The 500 yen coin 46 stopped by the mixing prevention stopper 50 is returned to the return passage 42 by the return operation.
Be dropped by. That is, when the return knob 13 is operated and the return lever 38 is lowered, the return side holding guide 45 is opened in association with the return lever 38, and the hundred-yen coin 43 of the stacking holding portion is dropped into the return passage 42. Then, since the 100-yen coins 43 are no longer present in the stack holding unit, the mixing prevention stopper 50 returns to the position shown by the solid line in FIG.
500 yen coin 46 is returned by the regulation by the return passage 42
Dropped to the side.

The vending machine of this embodiment is also provided with a mechanism for preventing the merchandise from being picked up. There are two types of this mechanism. One is a mechanism that prevents the product from being thrown out and the coins are returned at the same time by operating the lever, and the other is a stopper when the 100-yen coin 43 enters the stack holding unit. This is a mechanism for preventing illegal ejection, in which the detection piece portion 48a of 48 is pushed and the regulation of the ejection lever 25 is momentarily released.

First, the mechanism for preventing simultaneous ejection of goods and return of coins by the lever operation is constituted by the pressing link plate 39. That is, when the pressing link plate 39 is rotated in association with the return lever 38 as described above, the pressing link plate 39 enters below the stopper screw 40 on the ejecting lever 25 side to eject the ejecting lever 25.
A stopper portion 39c is provided to prevent further downward movement of the return lever 38. Therefore, when the return lever 38 is operated, the operation of the ejection lever 25 is prevented. When the operation of the ejecting lever 25 is slightly quick, the pressing link plate 3
9 cannot rotate and the operation of the return lever 38 is blocked.

Next, a system for assembling the product original filling type vending machine and replenishing, selling, installing and collecting the products will be described.
