Description

Известен способ контрол  монет, например, в торговых автоматах,, по соответствию комплекса их физических свойств: электропроводимо-, сти, магнитной проницаемости и размеров, установленному эталону, путем введени  испытуемых монет в электромагнитное поле индуктивно; св занных катушек, из которых первична  соединена с источником питани , а вторична  - с устройством, компарирующим электрические сигналы, и проверки равенства напр жени , индуктируемого во вторичной обмотке, эталонному.The known method of controlling coins, for example, in vending machines, according to the compliance of a complex of their physical properties: conductivity, magnetic permeability and size, to the established standard, by injecting test coins into an electromagnetic field; associated coils, of which the primary is connected to a power source, and the secondary coil is connected to a device that compresses electrical signals, and checks for the equality of the voltage induced in the secondary winding to a reference one.

Предлагаемый способ контрол  монет отличаетс  от известных тем, что дл  контрол  монет при их непрерывном движении и испытании, вли ни  на точность контрол  толчков и вибраций автомата монегь пропускают через электромагнитные пол  нескольких пар индуктивно св занных катушек, а определение соответстви  монет производ т па совпадению во времени напр жений, равных эталонным во вторичных катушках всех указанных пар.The proposed method of controlling coins differs from those known in that, in order to control coins during their continuous movement and testing, the accuracy of the control of the jolts and vibrations of the automaton allows several pairs of inductively coupled coils to be passed through the electromagnetic fields, and matching the coins to time voltages equal to the reference in the secondary coils of all these pairs.

В описываемом способе контрол  монет по соответствию комплекса физических свойств монет: электропроводимости, магнитной проницаемости и размеров, установленному эталону испытуемые монеты пропускают через электромагнитные пол  двух или нескольких пар индуктивно св занных катушек.In the described method of controlling coins by matching the complex of physical properties of coins: electrical conductivity, magnetic permeability and size, to the established standard, the tested coins are passed through the electromagnetic fields of two or more pairs of inductively coupled coils.

На первичные обмотки 1 и 2 этих катушек (см. чертеж) подают напр жение высокой частоты от источника 3. Электромагнитными пол ми , образуемыми первичными обмотками, во вторичных обмотках 4 к 5 катушек индуктируетс  напр жение, величина которого зависит от величины зазора между обмотками (посто нного дл  данного монетопровода ), электропроводимости испытуемой монеты, ее магнитной проницаемости и геометрических размеров.The primary windings 1 and 2 of these coils (see drawing) supply the high frequency voltage from source 3. The electromagnetic fields formed by the primary windings in the secondary windings 4 to 5 of the coils induce a voltage, the value of which depends on the size of the gap between the windings ( constant for a given coin line), electrical conductivity of the tested coin, its magnetic permeability and geometrical dimensions.

Напр жение, характеризующее годность монеты, получаетс  только в том случае, если в какой-то момент времени пролета монеты через обмотки катушек как на первичных, так и на вторичных их обмогThe voltage characterizing the suitability of a coin is obtained only if at some point in time the coin flies through the windings of the coils on both the primary and secondary currents.
