All-automatic coin sorter
Technical field
The present invention relates to a kind of coins to arrange machinery, and in particular to a kind of the 5th set of coin that can realize three kinds of face amounts
Separation counts, the all-automatic coin sorter of unitary coin false distinguishing.
Background technology
Coin is as one of common currency in a kind of world wide, with sturdy and durable, not easy to wear, making essence
U.S., uniform specification, readily identified, easy to use etc. be many to be widely used in a little business, traffic, communication, amusement and various
In automatically vending system.China has issued 5 sets of coins so far, and is involved in circulation.
However repeatedly there is news report to show that minor coin produces big problem, on October 22nd, 2009, southern News Network
First entitled " why coin frequency suffers rejection " reported, is reported:" coin, as a kind of legal tender of national public publication,
The important function of odd lot and daily small change is played in circulation, development prospect is good for financial figures always.However
City's most area especially rural area, a large amount of coin but frequently meet with the embarrassment of rejection in bank." wherein there is any to cause
My attention:" it is reported that since many financial institutions of China do not check specially, tie up, pack and the equipment of conveying coins,
Multiple working procedure is still parked in level hand-manipulated at present, and labor intensity is big, and working efficiency is low.And base's clothes of some financial institutions
The vocational window of business site is again few, and to look after the people of other transacting business that come, the coin exchange of wholesale is all easy to be refused
Absolutely." till now, it still can be frequently seen the news of similar report " so-and-so citizen go to bank, bank to reject by mass of coins ".
One because mass of coins is checked time-consuming and laborious, and equally there is presently no suitable coin discrimination equipment, this allows bank to coin
It hangs back.Equally, more public transport companies also face similar problem, and the coin received every year is bad to be checked, and is faced
A large amount of counterfeit coin problem.
Therefore, it can be seen that it is pseudo- to the inspection of coin, to check research critically important.But China starts late in this respect, initially
Cooperate to copy the machine of Japan by Tsinghua University and Kunming lathe Co., Ltd, but perfect cannot realize function and still locate
In conceptual phase, multiple universities domestic later and enterprise add research ranks.Up to the present, Nanjing Aero-Space University,
The schools such as HeFei University of Technology have now been developed the theoretical model of large-scale Coin processing device.Hebei Shang Tong Electronics Co., Ltd.s are also
Small-sized Coin sorting counter device is produced through design.
For external Coin processing device, either large-scale or small-sized has certain level, and technology is more ripe,
But it is expensive, and domestic coin system is not adapted to.Domestic large-scale processor is other than import, although carrying out
Some are imitated, but since technical problem not can manufacture, and the occasion that large-scale processor adapts to is limited, and general bank etc. is small
Type enterprise will not purchase, and can not popularize.Although sorting function may be implemented in domestic small coin processor, but it is pseudo- to be a lack of inspection
Link, therefore research one kind can realize that Coin sorting, identifier device are meaningful.

Motor 101 is forward and reverse is alternately rotated for sorting, is led to ensure that coin is arranged in order to enter by straight slot by vibration
Rail.
Rectangle groove width 14mm on the linear ramp of guide rail 103, and side and rectangular channel of the linear ramp far from circular arc slideway
Homonymy lateral distance 6mm.
Motor 101 and false distinguishing motor 302 are sorted by control module drive control, control module includes PIC series monolithics
Machine and its extension motor drive ic ULN2003.
Working principle of the present invention is as follows:
Start button is pressed, motor 101 is sorted and false distinguishing motor 302 starts, the coin largely mixed is poured into cylinder 102
In, sorting motor 101 drives the turntable rotation in cylinder 102, the coin in cylinder 102 under the action of gravity and centrifugal force according to
Secondary arrangement is by the straight slot on cylinder 102, into guide rail 103, and along linear ramp far from circular arc slideway side glide downwards.
A diameter of 19.5mm of dime, a diameter of 20.5mm of half a buck, unitary coin diameter is 26mm, and straight line
The not homonymy lateral distance of side and rectangular channel of the slideway far from circular arc slideway is 20mm, therefore dime will fall into first firmly
Coin exports, into the first pipe 104.And five jiaos, unitary coin will continue glide downwards by rectangular channel.The thickness of half a buck
Thickness for 1.65mm, unitary is 1.85mm, and 105 lower surface of fixed block and linear ramp surface distance on guide rail 103
For 1.75mm, therefore half a buck will be skidded off by block from linear ramp end, and into the second pipe 106, and unitary coin will
Enter circular arc slideway along block 105, and skidded off from circular arc ways-end, into third pipe 301.
When one piece of coin passes through Hall sensor, Hall sensor will send a pulse signal to control module, control
Molding root tuber counts coin according to pulse signal quantity.According to this principle, be fixed on the first pipe 104 first suddenly
Your sensor 202 and the second Hall sensor 201 being fixed on the second pipe 106 record respectively from pipe by one jiao
With half a buck quantity.Unitary pile in third pipe 301, synchronous belt 303 is under the drive of false distinguishing motor 302 every 2s by one
Piece coin is sent into the 4th pipe 309.Unitary coin is fallen by the 4th pipe 309 on pressure sensor.Pressure sensor is examined
It measures coin weight and is transferred in control module, control module compares the gravimetric value received and true unitary coin gravimetric value
Compared with the unitary coin is genuine note if weight is identical, and the unitary number of coins of record adds 1, and the pop-up of the first electromagnetism push rod 304 will
Genuine note is pushed into unitary coin receptacles.The unitary coin is counterfeit money, the second electromagnetism push rod 308 pop-up, by counterfeit money if varying in weight
It is pushed into counterfeit money container.
