JPH01232490A - Coin shoot for automatic vending machine - Google Patents

Abstract

PURPOSE:To prevent such a liquid that is forcibly supplied by the mischief, etc., from flowing into a coin mechanism by providing plural zigzag cut riser pieces onto the lower guide surface of a coin shoot and providing a rotatable impeller into a coin path. CONSTITUTION:A rotatable impeller 8 is provided into a coin path 7 and supported on the side surface of a coin shoot 4 at the periphery of a slit hole 2a of a coin shoot 2 and at a point before the end part of a drain port 4c. Thus a liquid, even if supplied forcibly from a detergent container 9, etc., and flowed into a main body 1 through the hole 2a as shown by a single-dot chain line B, drops down by means of the impeller 8 and is led into a shoot 6 via the cut riser pieces 4b. Then the liquid flows down along the back side of the main body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vending machine, and more particularly to an improvement of a coin chute for guiding coins inserted from a coin slot to a receiving slot of a coin mechanism. .

Conventional technology vending machines are often installed outdoors, such as under the eaves of a storefront. For this reason, during rainy weather, rainwater may enter the coin slot and flow into the coin mechanism via the coin chute. Furthermore, in recent years, there have been cases in which highly viscous liquids such as detergents have been accidentally injected into coins, which can cause failures such as coins getting stuck in the coin mechanism or contact failure due to water leakage.

Conventionally, as a countermeasure to this problem, a method has been considered, as disclosed in Japanese Utility Model Publication No. 58-6059, in which a large number of round or square holes are provided in the guide surface at the bottom of the coin chute, and rainwater that has entered through the holes is drained.

Problems to be Solved by the Invention However, with such a conventional configuration, it is inevitable that rainwater under strong winds and mischief caused by highly viscous liquids will flow into the coin mechanism. To prevent this, the hole should be made large enough and the coin chute long enough, but if the hole is made large, the edge of the inserted coin will get stuck in the hole, causing the coin to jam inside the coin chute. This results in the occurrence of Furthermore, some vending machines have a structure in which the coin chute cannot be made sufficiently long.

Therefore, in view of the above-mentioned problems, the present invention has been developed to provide a coin vending machine that can reliably drain liquid such as rainwater that has entered the coin slot into the outside without flowing into the coin mechanism, and that also eliminates the risk of coin jamming. It provides a shot.

Means for Solving the Problems In order to solve the above problems, the present invention provides a drainage port on the lower surface of the coin chute and a rotatable impeller in the coin passage.

Accordingly, the present invention provides a rotatable impeller in the coin passage to guide the liquid flowing in with force to the outside of the coin chute.

Example An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, 1 is the main body of the vending machine, and a coin slot 2 is provided on the front side of the main body 1. The coin slot 2 has an inclined slit hole 2a and is configured to receive a coin 3 at a slight angle.

A coin 3 inserted through a coin input slot 2 is led to a coin chute 4. This coin chute 4 is for guiding the coin 3 to the receiving port 5aiC of the coin mechanism 6, and is inclined downward, has a lower part bent downward, and has a guide surface 4a at the lower part. Further, on the guide surface 4a, a plurality of cut and raised pieces 4b are provided downwardly in a staggered manner to form drain ports 4c. A gutter 6 is formed below the cut and raised piece 4b, and guide surfaces θa are formed upward on both sides of the sloped surface of the gutter 6.
installed on.

On the other hand, in the coin passage 7, a rotatable impeller 8 is provided near the slit hole 2a of the coin input port 2 and in front of the rearmost part of the drain port 4C and is supported by the side surface of the coin chute 4. It is being

With such a configuration, liquid such as rainwater or detergent that has entered from the coin slot 2 flows along the guide surface 4a as shown in FIG. It falls as shown by the dotted chain line A, is collected in the gutter 6, and falls along the back surface of the main body 1.

Also, as shown in Fig. 4, even when the liquid is forcefully pumped with a commercially available detergent container 9, etc., the pumped liquid flows forcefully into the slit hole 2a of the coin slot 2 as shown by the dashed line B. The impeller 8, which is rotatable, falls to the bottom by the rotatable impeller 8, and the rotatable impeller 8 is inserted into the slit of the coin slot 2. hole 2
Since it is placed near point a, when it is forcefully fed, it falls to the bottom by the rotatable impeller 8 and is collected in the gutter 6 through the cut and raised pieces 4b, and the back surface of the main body 1 is fall along.

Effects of the Invention The present invention provides a plurality of staggered cut-and-raised pieces on the lower guide surface of the coin chute and a rotatable impeller in the coin passage, thereby preventing not only normal rain but also mischief etc. The coin chute itself handles liquid that is thrown in forcefully to prevent it from flowing into the coin mechanism, and can be easily handled by changing only the reed and conventional coin chute.
