Description
Technical field
The utility model is related to a kind of Intelligent coin identify small change device, more particularly to it is a kind of collection false distinguishing, sorting, storage,
The Intelligent coin identification small change device that small change and management are integrated.
Background technology
Automatic vending machine reduces the cost manually sold.Japan, the population in the U.S. are far smaller than China, but they are each
Country has four or five million vending machines runing, and the country is less than 300,000 in the vending machine quantity of operation at present.With
Expanding economy, cost of labor can be higher and higher, and the advantage being sold is made of automatic vending machine can be more and more apparent.
Intelligent coin identification small change device is the important component of automatic vending machine, can influence the popularization model of automatic vending machine
It encloses and speed.Current Intelligent coin identification small change device has the following problems：
1) the coin coin bucket of Intelligent coin identification small change device is divided into according to the quantity of coin bucket：Individual layer coin coin bucket and bilayer are hard
Two kinds of structures of coin coin bucket.Using individual layer coin coin bucket, the number of coins of storage is fewer, it is necessary to which staff frequently pays close attention to coin
Reserves, dress coin frequency are high；Using double-deck coin coin bucket, the quantity for storing coin adds.The device for change-giving of coin of company of Fuji is
Double-deck coin coin bucket, but wherein one layer is only opened, another layer cannot be opened, and the device for change-giving of coin of MEI and NRI companies is bilayer
Coin coin bucket, cannot open for two layers, and the quantity of the device for change-giving of coin storage coin of both structures adds, but it is difficult to fill coin
The problem of degree is big, efficiency is low, it is necessary to be packed into coin one by one from coin bung hole.
2) in Intelligent coin identification small change device coin is set to survey counting apparatus, filling coin for staff provides foundation.At present
Device for change-giving of coin usually detect number of coins in coin bucket using the mode of infrared lamp, Eddy current test and ultrasonic wave.It is wherein sharp
With the transmitting of infrared lamp and the device of reception detection number of coins, survey number results contrast is accurate, but device is to use environment
It is more demanding, in the more severe occasion of environment, as its test result is inaccurate when dust is very big, and need often dimension
Shield, the difficulty of maintenance are also larger.Using the device of EDDY CURRENT number of coins, testing result is inaccurate, can only have to coin-out bucket
Without coin, particular number can not be provided, if the vortex of Japanese fuji surveys counting apparatus, less than 10 pieces are just determined as sky, and error is larger.
3) locating turntable is one of important component of Intelligent coin identification small change device, and Intelligent coin identifies small change device by turning
The rotational positioning of disk screws out coin from coin bottom of the barrel, so as to fulfill the purpose of coin change.Current device for change-giving of coin turns
The rotation positioning device that spirals controls the rotational positioning of turntable usually using self-reflection infrared sensor, and contrast locating is more accurate.But
After infrared sensor long-time energization use, can there are problems that infrared optical attenuation, and infrared sensor light head and
Reflecting surface is easily dirty in the case where working environment is relatively more severe, therefore the turntable rotation positioner based on infrared sensor needs
Often to safeguard dust, and maintenance cost is higher.
4) in order to ensure the normal operation of Coin validator, it is necessary to which periodically internal part is overhauled and safeguarded.It is examining
During repairing and safeguarding, false distinguishing and the coin separating device of current Intelligent coin identification small change device are in the protecgulum of coin coin passage
After plate is opened, due to lacking object support front shroud, front shroud can be restored to closed form under the effect of the elastic force of protecgulum flat spring
State.In order to continue to being overhauled and being safeguarded inside Intelligent coin identification small change device, it is necessary to front shroud is helped always with a hand,
And only overhauled with one hand and maintenance is inconvenient, and also affect the effect of maintenance.
Utility model content
The technical issues of the utility model solves is to provide a kind of Intelligent coin identification small change device, has taken into account dress coin and held
Amount, dress coin convenient degree, coin bucket coin reserves survey number precision, dig coin turntable positioning accuracy and the security of maintenance.
Realize purpose of utility model technical solution be：A kind of Intelligent coin identifies small change device, including main frame, with
And the false distinguishing being arranged in main frame surveys counting apparatus with coin separating device, coin coin bucket, touch display screen, coin and digs coin device,
Wherein：
False distinguishing and coin separating device are located at the top of main frame, for identifying the true and false of coin and face amount, and according to face amount into
Row coin is grouped；
Touch display screen is located at the lower section of false distinguishing and coin separating device, for man-machine information interaction；
Coin coin bucket position is in the lower section of touch display screen, for storing the coin of different denominations；
Coin is surveyed counting apparatus and is located between false distinguishing and coin separating device and coin coin bucket, for detecting the coin number in coin bucket
Amount；
It digs coin device to be located at below coin coin bucket, for exiting corresponding coin according to small change number.
The utility model compared with prior art, remarkable advantage：1) human-computer interaction is carried out using touch display screen, it can be with
The usage log of real time inspection machine, it is convenient to be provided to Solve on site problem, and operating personnel need to input by touch display screen
Password ability login system carries out relevant set and operates, set caused by can effectively prevent other staff's maloperation toggle switch
It is standby to use problem, reduce unnecessary maintenance work；2) false distinguishing and coin separating device set spanner between pedestal and front shroud, when
Front shroud withstands front shroud, easy access after opening, and reduces finger and have little time the risk crushed after removing；3) coin bucket is set
Be set to bilayer, more coins can be packed into, using can Unclosing structure, it is more convenient to use quick, and by positioning pin and
Location hole ensure that the precise positioning and bearing strength of coin bucket.4) survey counting apparatus is simple in structure, and survey counting method is efficient and convenient, shows
It writes and improves the accuracy and speed that coin surveys number, the error that coin surveys number is controlled in 2 pieces；Surveying counting apparatus can compare in environment
It is worked normally in the case of severe, reduces maintenance cost and difficulty；5) turntable rotation positioner control turntable positions more
Accurately, and safeguard more convenient.
