Description

Beschreibungdescription

Die Erfindung betrifft einen elektronischen Münzprüfer, mit welchem es möglich ist,Münzen mit verschiedenen Metalllegierungen voneinander zu unterscheiden. Sin nach dem bisherigem,bekannten Verfahren hergestellter Münzprüfer für Warenautomaten kann nur nach Maß und Gewicht, sowie nach dem magnetischem Verhalten der Münze unterscheiden. Das Unterscheiden von magnetischen und unmagnetischen Münzen wird,wie bekannt,mit Hilfe eines Dauermagneten,weIcher in der Münzkanalwand des Münzprüfers eingebaut ist,erreicht. Um dem immer häufiger auftretenden Automatenbetrug vorzubeugen, ist es nicht mehr ausreichend, nur nach Maß,Gewicht und magnetischem Verhalten zu unterscheiden.Eine Vielzahl von ausländischen,sowie älteren innländischer Münzen sind nach Maß,Gewicht und magnetischem Verhalten unseren derzeitigen gültigen innländischen Münzen so genau gleich,daß eine Unterscheidung nach den bisherigen Verfahren nicht möglich ist.The invention relates to an electronic coin validator with which it is possible to check coins with different metal alloys to distinguish from each other. Sin produced according to the previous, known process Coin validators for vending machines can only be made to measure and weight, as well as according to the magnetic behavior of the coin. Differentiating between magnetic and non-magnetic coins is, as is known, with the help of a permanent magnet, which in the coin channel wall of the coin validator is built in. In order to prevent the increasingly frequent occurrence of machine fraud, it is no longer sufficient just to measure, weight and magnetic behavior. A variety of foreign, as well as older domestic coins are after Measure, weight and magnetic behavior are so exactly the same as our currently valid domestic coins that a distinction is not possible under the previous procedures.

FunktionsbeSchreibung des elektronischen Münzprüfers: Wird eine Münze zwischen zwei Spulen gebracht,so wird deren Kopplung beeinflußt.Wie aus Zeichnung I ersichtlich ist, wird in einer Spule mit Hilfe eines Generators ein Induktionsfeld erzeugt,wodurch in der zweiten Spule eine Induktionsspannung infolge Kopplung der beiden Spulen zu messen ist. Je nach Metall und Legierung der dazwischen liegenden Münze wird nun die induzierte Spannung in der zweiten Spule mehr oder weniger geschwächt und gibt somit eine Möglichkeit verschiedene Münzen nach ihrem Dämpfungsverhalten zu unterscheiden. Wird nun eine Anordnung der Spulen nach Zeichnung II getroffen,so ergibt sich die Möglichkeit,zwei Münzen direkt miteinander zu vergleichen.Dabei wird zwischen Spule 2 und eine echte Münze gebracht,während zwischen Spule 2 und 1 dieFunctional description of the electronic coin validator: If a coin is placed between two coils, their coupling is influenced. As can be seen from drawing I. an induction field is generated in one coil with the aid of a generator, which creates an induction voltage in the second coil is to be measured due to the coupling of the two coils. Depending on the metal and alloy of the coin in between the induced voltage in the second coil is now weakened to a greater or lesser extent and thus offers a possibility differentiate between different coins according to their damping behavior. If the coils are now arranged according to drawing II, there is the possibility of two coins directly A real coin is placed between reel 2 and, while between reel 2 and 1 the

unbekannte bzw. die zu prüfende Münze gebracht wird.Die Spulen, 1 und 3 sind so geschaltet,daß sich die Spannung der beiden Spulen in ihren Vorzeichen unterscheiden.Ist somit die induzierte Spannung der Spule 1 gleich der induzierten Spannung von Spule 3, ist die Summe beider Spannungen Null.Der nachfolgende Verstärker bekommt also bei Gleichheit der beiden induzierten Spannungen von Spule 1 und 3 keine Wechselspannung an seinen Eingang.Durch eine derartige Anordnung ist es nicht nur jederzeit möglich, ein und den selben Münzprüfer für verschiedene Münzen zu benützen ,indem einfach in den Ausschnitt zwischen Spule 2 und eine dementsprechende Münze als Vergleichsstück gelegt wird, sondern es ergeben sichdaraus sehi? stabile elektrische Zustände bei Änderung von Umgebungstemperatur oder der Versorgungsspannung des Generators sowie Verstärkers.Sobald die Münze zwischen Spule 1 und 2 eine andere Dämpfung als die Münze zwischen Spule 2 und 3 aufweist,ist die induzierte Spannung von Spule nicht gleich groß wie die von Spule 3»wodurch am Verstärkereingang eine Wechselspannung von der Größe der Differenz der beiden Spannungen auftritt.Die im Verstärker verstärkte Wechsel-Spannung wird gleichgerichtet und schaltet,wenn dieDifferenzäpannung am Eingang des Verstärkers groß genug ist,ein Relais, welches über eine mechanische Anordnung eine Weiche betätigt. Mit dieser Weiche wird die geprüfte Münze bei Gleichheit der beiden Münzen in den Kanal für richtige Münzen geleitet,bzw. bei nicht gleichen Münzen in den Kanal zur Geldrückgabe geleitet.unknown or the coin to be checked is brought in. The coils, 1 and 3 are connected so that the voltage of the two The sign of the coils is different, so if the induced voltage of coil 1 is equal to the induced voltage of coil 3, If the sum of both voltages is zero, the following amplifier receives the induced voltages if the two voltages are equal from coil 1 and 3 no alternating voltage at its input. With such an arrangement it is not only possible at any time, to use one and the same coin validator for different coins by simply inserting into the cut-out between coil 2 and a corresponding coin is placed as a reference piece, but does it result from it? stable electrical states when the ambient temperature or the supply voltage changes of the generator as well as amplifier. As soon as the coin between coil 1 and 2 has a different damping than the coin between Coil 2 and 3 is the induced voltage from Coil not the same size as that of coil 3 »which is why at the amplifier input an alternating voltage with the magnitude of the difference between the two voltages occurs. The alternating voltage amplified in the amplifier is rectified and switches when the differential voltage at the input of the amplifier is large enough, a relay which actuates a switch via a mechanical arrangement. With this switch, the checked coin is passed into the channel for correct coins if the two coins are the same. if the coins are not the same, it is directed into the channel for money return.

Wird der Generator sowie der Verstärker mit Transistoren aufgebaut,so ist die Anordnung nicht nur sehr klein,sondern es sind mit einer Taschenlampenbatterie herkömmlicher Bauart viele fausend Prüfvorgänge durchführbar.Hierbei wird jeweils durch die eingeworfene Münze der Münzprüfer über einen Kontakt ein- und ausgeschaltet.If the generator and the amplifier are built with transistors, the arrangement is not only very small, but Many thousands of test procedures can be carried out with a conventional flashlight battery The coin validator is switched on and off via a contact by the inserted coin.

Gewerbliche Anwendungsmöglichkeiten:Commercial applications:

1. Hauptanwendungsgebiet ist der Einbau in Warenautomaten, welche durch Einwurf von Münzen betrieben werden.1. The main area of application is the installation in vending machines which are operated by inserting coins.

2. Auch auf dem Gebiet der Münzgeldsortierung bei Geldinstituten kann eine solche Anordnung vollautomatisch eingesetzt werden.Ein wesentlicher Vorteil ist hierbei, daß2. Such an arrangement can also be used fully automatically in the field of coin sorting at financial institutions A major advantage here is that

Die Kennzeichen für den wesentlichen Portsehritt: Mit dieser Art von Prüfung der Münzen ist die Möglichkeit gegeben,auch Münzen voneinander zu unterscheiden,welche sich in Form,Maß und Gewicht,sowie im magnetischem Verhalten gleichen.Um die Unterscheidung zu ermöglichen ist es lediglich notwendig,daß die Legierungen der Münzen voneinander abweichen. Eine derartige Unterscheidungsmöglichkeit ist mit den bisherigen,bekannten Prüfmethoden nicht möglich. z.B.:Die tschechische 5 Kronen Münze wird von der 1 DM Münze mit dem elektronischen Münzprüfer einwandfrei unterschieden.The characteristics for the essential port step: With this type of examination of the coins it is possible to distinguish between coins and which ones are different in shape, size and weight, as well as in magnetic behavior In order to make the distinction possible it is only It is necessary that the alloys of the coins differ from one another. Such a differentiation is possible with the previous, known Test methods not possible. E.g.: The Czech 5 kroner coin is derived from the 1 DM coin clearly distinguished with the electronic coin validator.
