Abstract

A kind of slot machine that uses Renminbi.In the monobasic coin input machine, after the identification of true and false coin, by rolling counters forward, the result send computing machine.Purchaser is pressed the corresponding cargo number pushbutton switch of shipment keyboard, if it is identical with value of goods that computing machine relatively drops into the currency numerical value that comes, then driving circuit rotates servomotor and drives travelling belt, perhaps motor rotates with the goods release screw, and these two kinds of methods make first goods in prostatitis in vertical arrangement goods leave the warehouse and fall into the goods groove.Purchaser can be got the goods of purchase in the goods groove.Return in the goods falling process and return 0 signal to one in computing machine, motor shuts down.The present invention can realize the automatic sale of multiple article, and have can will drop into the function that all withdraws from of coin.

Description

Coin-freed vending machine

The present invention relates to a kind ofly can realize self-service device with throwing the coin mode, use monobasic Renminbi coin can sell multiple goods, and each price of goods can be preset at monobasic to seven yuan.The function that can withdraw from the whole coins that dropped into is arranged.

Slot machine is existing abroad, the domestic stamp machine of inserting coins, and the card vending machine of inserting coins does not also occur the automatic vending machine that can sell multiple goods and multiclass goods.This machine uses the Renminbi coin.

The object of the present invention is achieved like this: coin enters the machine inner slide from coin slot, slide into the slideway lower end by under the self gravitation, insulation tongue piece by a band semilune breach is held, the coin outer rim contacts with three contacts that half round cut is equally spaced, coin is an electric conductor, and a charged contact can make also positively charged position of two other contact.Circle has a telefault outside tongue piece, tank with the capacitor composition, the stop of coin has changed oscillation frequency, contiguous have a receiving coil and capacitor resonance in this frequency on the telefault side, in this frequency modulated audio frequency through the receiving circuit detection obtain a direct-flow positive voltage amplify in back and three contacts two quilts with on the positive voltage that comes of positive voltage contact deliver to one three input end of going into to hold Sheffer stroke gate simultaneously, the output terminal current potential makes a monostable circuit triggering by high step-down.Other sheet metals of different sizes and different quality can not make contact obtain positive potential or receiving coil and capacitor and obtain correct frequency, thereby this monostable circuit is triggered.Monostable triggers the back output terminal and becomes noble potential by electronegative potential, after amplifying, transistor promotes an electromagnet, electromagnet armature is fixed on the tongue piece lower end, its suction is moving to cause that tongue piece moves up, coin on the semilune breach loses and stops, downslide drops into the coin of below and deposits in the dish, and this moment, monostable circuit also made the coin counter output terminal add " 1 ", and demonstrated the quantity that drops into coin on the cabinet outer panels.

When the voltage of pressing certain numbered button on the keyboard from the shopper, be added to one three simultaneously when going into to hold three of Sheffer stroke gate to go into to hold with voltage on the counter and train pulse voltage, output terminal starts a monostable circuit, thereby make drive circuit works, servomotor is rotated, the driven by motor conveyer belt, the goods on the travelling belt is pushed away forward, and a top goods drops to getting in the goods groove of below.The light-path of shading light electric inductor quits work driving circuit in the goods falling process, the goods stop motion.This machine has five cover travelling belts can sell five kinds of box-packed goods.

Hanging a bag shipment mode is that the goods that the Luo Xuanti rotation will be gone here and there on steel bar pushes away to the front, and the most previous steel bar that is pushed out drops to and gets in the goods groove, stops operating voluntarily after Luo Xuanti rotates a circle.This machine has five cover Luo Xuan body and circuit, can sell five kinds of bags and hang goods.

Shipment also makes simultaneously and drives the motor rotation that coin is deposited dish, and coin is deposited dish to the slideway overturning of leading to the box of collecting money, and all coins all slip in the box of collecting money in the dish.

When pressing " having the money refunded " button, the whole coins of depositing dish of falling that dropped into are all swung to the slideway that leads to " mouth of having the money refunded ", and mouth withdraws from outside the machine from having the money refunded.

Below in conjunction with drawings and Examples invention is further specified.
