Description

Retractable Packaging Coin Dispenser

The present invention relates to a lift pouch withdrawal machine, and more particularly, by automatically withdrawing a coin wrapped in a certain amount by a desired amount, reducing the customer waiting time required to exchange banknotes into coins in the bank, and the cashier's hand It is about a retractable pouch coin dispenser that can relieve the problem.

In modern society, the spread of various credit cards that can be used as second cash is increasing. However, despite the spread of credit cards, cash is still used as the most widely used payment method. Although there are differences between countries, most countries issue two types of money as cash payments. In other words, money may be issued in bills or coins, depending on the size of the amount. In some cases, the same amount of money may be issued for both bills and coins.

Coin, which is one of such payment methods, is indispensable in commerce such as a general store or a convenience store, and a large amount of coins are paid in change every day. Currently, most people exchange banknotes for coins, so each branch of the bank prepares 50 to 100 coins for each amount and exchanges the coins for customers. As a result, banks either arrange a separate employee in charge of currency exchange or handle currency exchange at general counters.

In addition, each bank's stores and small withdrawal corners have cash dispensers that can withdraw cash in 10,000 won units or self-checks in 100,000 won units, but do not have equipment for withdrawing coins. There is no choice but to ask the counter staff.

In the process of exchanging pavement coins in this way, there is a inconvenience that many people have to wait until their turn in stores without a dedicated currency exchange counter. From the bank's point of view, it is necessary to take the waste of manpower in assigning a separate teller, and even if a dedicated teller is not assigned, the general teller must perform coin exchange work, which causes a decrease in work efficiency.

The present invention devised to solve such a problem is to automatically withdraw a certain amount of coins to the required amount, thereby providing a retractable packaging coin dispenser that can reduce unnecessary customer waiting time and reduce the work of the bank staff. The purpose is.
