Description

Die Erfindung bezieht sich auf einen Münzprüfer nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a coin validator according to the preamble of the claim 1.

Münzgeräte sind häufig so ausgelegt, daß sie die Annahme von Münzen unterschiedlicher Wertigkeit zulassen. Der Münzprüfer erzeugt Signale (Wertigkeitssignale), welche repräsentativ sind für die Anzahl der eingeworfenen Münzen und ihre Wenigkeit. Mit Hilfe eines Kreditwerkes kann dann bestimmt werden, ob der Betrag der eingeworfenen Münzen einem vorgegebenen voreingestellten Preis entspricht, wodurch dann die Ausgabe einer Ware, eines Fahrscheins oder dergleichen stattfindet. Ein derartiger Münzprüfer ist aus EP-A-0 167 181 bekannt geworden. Er weist außerdem Münztuben auf, in die Münzen nach Wertigkeit gestapelt werden. Die Münztuben haben eine Füllstandsbegrenzung, die verhindert, daß die maximale Stapelzahl der Münzen überschritten wird.Coin operated machines are often designed to accept different coins Allow valency. The coin validator generates signals (value signals) which are representative of the number of coins and yours. With the help of a credit facility, it can then be determined whether the Amount of coins inserted at a pre-set price corresponds to what then the issue of a commodity, a ticket or the like takes place. Such a coin validator is known from EP-A-0 167 181 become. It also has coin tubes, into which coins are valued be stacked. The coin tubes have a level limit that prevents that the maximum number of stacks of coins is exceeded.

Auf dem deutschen Markt und anderen Märkten befindet sich ein erhebliches Volumen von sogenanntem Fremdgeld, das zum Beispiel in den deutschen Münzautomaten für 1-DM-Münzen akzeptiert wird. Dieses Fremdgeld ist nahezu wertlos, jedoch geeignet, dem Münzgeräteaufsteller erheblichen Schaden zuzufügen, zumal bei derartigen Geräten die 1-DM-Münze die Hauptmünze darstellt. There is considerable volume on the German and other markets of so-called foreign money, for example in the German coin machines for 1 DM coins is accepted. This outside money is almost worthless, however suitable to cause considerable damage to the coin dispenser, especially with such devices, the 1 DM coin is the main coin.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Münzprüfer zu schaffen, bei welchem der Schaden durch den Einwurf von wertlosen, gleichwohl akzeptierten Fremdmürizen reduziert wird.The invention is therefore based on the object of creating a coin validator which the damage by throwing in worthless, yet accepted Foreign currencies is reduced.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

Der erfindungsgemäße Münzprüfer weist einen Begrenzungsspeicherabschnitt in der Speicheranordnung auf, in dem die Wertigkeit einer zu begrenzenden Münzwertigkeit und ein Betragswert gespeichert sind, der einer vorgegebenen Anzahl von zu begrenzenden oder eine vorgegebene Summe der Werte der zu begrenzenden Münzwertigkeiten pro Verkaufsvorgang entspricht. Die von den in den Münzprüfer eingegebenen Münzen hervorgerufenen Wertigkeitssignale werden mit den gespeicherten Münzwertigkeiten verglichen und bei Übereinstimmung addiert oder in ihrer Anzahl gezählt und mit der vorgegebenen Anzahl oder der vorgegebenen Summe verglichen. Es wird ein Rückgabesignal für die zu begrenzende Münzwertigkeit erzeugt, wenn die vorgegebene Anzahl oder Summe über- oder unterschritten wird.The coin validator according to the invention has a limit storage section in the Storage arrangement in which the value of a coin value to be limited and an amount value is stored which corresponds to a predetermined number of to be limited or a predetermined sum of the values of the to be limited Corresponds to coin denominations per sales transaction. The coins entered into the coin validator evoked valence signals are saved with the Coin values compared and if they match added or counted in number and with the given Number or the specified sum compared. There will be a return signal for the coin value to be limited generated when the given number or sum is exceeded or fallen below.

Für die Realisierung der Münzannahmebegrenzung pro Verkaufsvorgang sind verschiedene Ausführungsformen möglich. Bei der einen Ausführungsform können zum Beispiel die begrenzten Münzen gezählt werden. Erreicht die Anzahl während eines Verkaufsvorgangs einen bestimmten Höchstwert, muß die Gesamtsumme für einen Kauf oder dergleichen durch Münzen anderer Wertigkeiten erreicht werden. Eine Erhöhung der Anzahl der begrenzten Münze führt zu einer Sperrung, d.h. zu einer Rückgabe der begrenzten Münze und damit automatisch nicht zu einem Abgabevorgang im Automaten. Zusätzlich kann vorgesehen sein, daß eine andere Münzwertigkeit bzw. mehrere andere Münzwertigkeiten gezählt werden, die einer nicht zu begrenzenden Münze zugehören. Die Anzahl dieser Münzen kann ebenfalls gezählt werden. Sie muß einen Mindestwert erreichen, damit ein Verkaufsvorgang durch Auslösen eines Kreditsignals vor sich gehen kann. For the implementation of the coin acceptance limit per sales transaction different embodiments are possible. For example, in one embodiment, the limited ones Coins are counted. Reaches the number during a certain maximum value of a sales transaction, must go through the total for a purchase or the like Coins of other denominations can be achieved. An increase the number of limited coins leads to a blocking, i.e. to return the limited coin and thus does not automatically result in a dispensing process in the machine. In addition, it can be provided that a different coin value or several other coin denominations are counted that one belonging to a coin that cannot be limited. The number of these Coins can also be counted. You must have a minimum value achieve a sales transaction by triggering it of a credit signal can go on.

Bei einer anderen Ausgestaltung kann zum Beispiel der Speicherabschnitt so wirken, daß bei einem Verkauf immer mindestens zwei Münzwertigkeiten auftreten müssen. Durch das Auftreten einer weiteren Münzwertigkeit wird automatisch die Anzahl der zu begrenzenden Münzen begrenzt. Nachteilig bei dieser Ausführungsform ist jedoch, daß keine Preise durch den Einwurf einer einzigen Münze, zum Beispiel einer 5-DM-Münze, entrichtet werden können.In another embodiment, the Storage section act so that when a sale always at least two coin denominations must appear. By the appearance of a further coin value becomes automatic limits the number of coins to be limited. A disadvantage of this embodiment, however, is that no prizes by inserting a single coin to Example of a 5 DM coin that can be paid.

Mit Hilfe einer bestimmten Logik kann daher beim erfindungsgemäßen Münzprüfer eine Annahmebegrenzung für eine oder mehrere Münzen verschiedener Wertigkeit erhalten. Eine komplette Sperrung von Münzen vorgegebener Wertigkeit ist normalerweise nicht sinnvoll. So ist für den deutschen Münzgeräteaufsteller unverzichtbar, die Annahme von 1-DM-Münzen zu ermöglichen. Wird jedoch eine Ware nur ausgegeben, wenn die Anzahl von Münzen der vorgegebenen Wertigkeit pro Verkaufsvorgang begrenzt ist, wird auch der Schaden, der durch den Einwurf von akzeptiertem Fremdgeld verursacht wird, begrenzt.With the help of a certain logic can therefore in the invention Coin acceptor a acceptance limit for one or received several coins of different values. A complete blocking of coins of a given value is usually not useful. That's how it is for the German Coin dispenser indispensable, the acceptance of 1 DM coins to enable. However, if goods are only issued, if the number of coins of the given value is limited per sales transaction Damage caused by the insertion of accepted foreign money is caused limited.

Es besteht die Möglichkeit, durch eine entsprechende Ausbildung der Logik jeder Münzwertigkeit eine eigene Annahmebegrenzung pro Verkaufsvorgang zuzuordnen. Die Anzahl von Speicherstellen in dem eingesetzten Speicher wird jedoch begrenzt, wenn erste Speicherstellen als Tabelle ausgebildet sind für die Zuordnung zu einer zweiten Speicherstelle für eine vorgegebene Münzwertigkeit. Bei dieser Ausgestaltung ist jedoch nur möglich, jeweils eine bestimmte Münzwertigkeit in der Annahme pro Verkaufsvorgang zu begrenzen. Dies entspricht jedoch den Erfordernissen heutiger Praxis. Automaten, insbesondere im sogenannten Außenbereich, mit denen zum Beispiel Zigaretten verkauft werden, nehmen 1-/2- und 5-DM-Münzen an, so daß die Verkaufspreise in 1-DM-Schritten eingestellt werden können, um beispielsweise den am gebräuchlichsten vorgegebenen Preis von DM 5,-- zu erreichen. Es brauchen daher nur die Schritte gezählt und einer vorgegebenen Münzwertigkeit zugeordnet zu werden, um die gewünschte Annahmebegrenzung pro Verkaufsvorgang zu verwirklichen. Nachstehend zwei Beispiele für den Betrieb des erfindungsgemäßen Münzprüfers:

  • 1. Preis: DM 5,--
    Begrenzte Münze: DM 1,--
    Maximale Anzahl der begrenzten Münze: 3
    Inhalt der ersten und zweiten Speicherstelle: (1) = 1 und (2) = 5-3 = 2
    Verkauf möglich: (1 x 5,-- DM) oder (2 x 2,-- DM + 1 x 1,-- DM) oder (1 x 2,-- DM + 3 x 1,-- DM)
    Wird der Preis auf 6 Schritte = 6,-- DM umgestellt, so kann der Preis mit einem 1,-- DM-Stück und einem 5,--DM-Stück oder 3 x 2,-- DM-Stücken oder 4 x 1,-- DM-Stück und einem 2,-- DM-Stück ohne Umprogrammierung erreicht werden.
  • 2. Preis: DM 5,--
    Begrenzte Münze: DM 2,--
    Maximale Anzahl der begrenzten Münze: 1
    Inhalt der ersten Speicherstelle (1) = 2 und der zweiten Speicherstelle (5-1x2 = 3)
    Verkauf möglich: (1 x 5,-- DM) oder (1 x 2,-- DM + 3 x 1,-- DM) oder (5 x 1,-- DM)
  • It is possible to assign a separate acceptance limit for each sales transaction by appropriately designing the logic of each coin value. However, the number of memory locations in the memory used is limited if first memory locations are designed as a table for the assignment to a second memory location for a given coin value. With this configuration, however, it is only possible to limit a certain coin value in the acceptance per sales transaction. However, this corresponds to the requirements of current practice. Vending machines, especially in the so-called outside area, with which, for example, cigarettes are sold, accept 1- / 2- and 5-DM coins, so that the sales prices can be set in 1-DM increments, for example at the most common predetermined price from DM 5 to reach. It is therefore only necessary to count the steps and assign them to a given coin value in order to achieve the desired acceptance limit per sales transaction. Below are two examples of the operation of the coin validator according to the invention:
  • 1st prize: DM 5, -
    Limited coin: DM 1, -
    Maximum number of limited coins: 3
    Contents of the first and second storage location: (1) = 1 and (2) = 5-3 = 2
    Sales possible: (1 x 5, - DM) or (2 x 2, - DM + 1 x 1, - DM) or (1 x 2, - DM + 3 x 1, - DM)
    If the price is changed to 6 steps = DM 6, the price can be changed with a DM 1 piece and a DM 5 piece or 3 x DM 2 pieces or 4 x 1 , - DM piece and a 2, - DM piece can be achieved without reprogramming.
  • 2nd price: DM 5, -
    Limited coin: DM 2, -
    Maximum number of limited coins: 1
    Contents of the first storage location (1) = 2 and the second storage location (5-1x2 = 3)
    Selling possible: (1 x 5, - DM) or (1 x 2, - DM + 3 x 1, - DM) or (5 x 1, - DM)
  • Nach einer Ausgestaltung der Erfindung können die Speicherstellen von Mikroschaltern gebildet sein, deren Stellung von einem Mikroprozessor bei jeder Kreditwerterzeugung abgefragt wird. Vor allen Dingen, wenn nur wenig Preise gespeichert werden, beispielsweise DM 5,-- und DM 12,--, stehen ausreichend Speicherplätze zur Verfügung, um die Logik des erfindungsgemäßen Münzprüfers zu verwirklichen. Sie hat außerdem den Vorteil, daß am Ort des Münzgerätes Preisumstellungen vorgenommen werden können, ohne daß die Annahmebegrenzung geändert werden muß. Allerdings wird hierbei in Kauf genommen, daß bei steigendem Preis die Anzahl der zu begrenzenden Münzen pro Verkaufsvorgang zunimmt, zum Beispiel von drei 1-DM-Münzen auf vier.According to one embodiment of the invention, the storage locations be formed by microswitches, their position queried by a microprocessor for each credit value generation becomes. Above all, if only a few prices are saved be, for example DM 5, - and DM 12, -, there are sufficient storage spaces available for the To implement logic of the coin validator according to the invention. It also has the advantage that at the location of the coin device Price changes can be made without the Acceptance limit must be changed. However accepted that with increasing price the number the coins to be limited increase per sales transaction, for example from three 1 DM coins to four.

    Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert.

    Bei der in Fig. 1 dargestellten Logikschaltung entspricht Block 10 einem in einem Speicher vorgegebenen Preis für eine Ware, der durch Einwurf von Münzen unterschiedlicher Wertigkeit erreicht werden kann. Für die echten Münzen erzeugt der Münzprüfer bei jedem Einwurf einer Münze ein Signal, daß repräsentativ ist für die Wertigkeit der Münze. In einem Kreditwerk 12 wird aufgrund der Signale ein Kreditwert erzeugt, der zu einem Verkauf gemäß Pfeil 14 führt, wenn der Wert des Kredites dem Preis entspricht.Corresponds to the logic circuit shown in FIG. 1 Block 10 a price for a predetermined in a memory a commodity made by inserting different coins Value can be achieved. Made for real coins the coin acceptor each time a coin is inserted Signal that is representative of the value of the coin. In a credit facility 12, a credit value is based on the signals generated, which leads to a sale according to arrow 14, if the value of the loan equals the price.

    Die Blöcke 16, 18, 20, 22 entsprechen den Münzwertigkeiten, die vom Münzprüfer bzw. Münzgerät akzeptiert werden. Bei jeder Münze einer vorgegebenen Wertigkeit gelangt das Signal über einen Annahmebegrenzungsblock 24, 26, 28, 30 auf das Kreditwerk 12. In der Annahmebegrenzung 24 bis 30 kann eingestellt werden, wieviel Münzen der vorgegebenen Wertigkeit für die Bildung eines Kreditwertes herangezogen werden können. Ist nach Sperrung der Anzahl der Münzen vorgegegener Wertigkeit der Preis der Ware noch nicht erreicht, müssen Münzen anderer Wertigkeit nachgeworfen werden, falls die Ware erworben werden soll.Blocks 16, 18, 20, 22 correspond to the denominations of coins, which are accepted by the coin validator or coin device. At every coin of a given value gets that Signal via an acceptance limitation block 24, 26, 28, 30 to the credit facility 12. In the acceptance limit 24 to 30 can be set how many coins of the given Value used for the formation of a credit value can be. Is after blocking the number of coins the value of the goods has not yet reached the specified value, coins of different value have to be thrown, if the goods are to be purchased.

    In Fig. 2 sind mit Fig. 1 gleiche Teile mit gleichen Bezugszeichen versehen, denen lediglich ein a hinzugefügt ist. In Fig. 2 ist ein Annahmebegrenzungsblock 32 vorgesehen, in dem zum Beispiel die maximale Anzahl einer anzunehmenden Münze eingegeben ist. In einer Tabelle 34 erfolgt die Zuordnung der Münzwerte gemäß den Blöcken 16a bis 22a zur Annahmebegrenzung 32, wobei jeweils nur ein vorgegebener Münzwert in einer Anzahl begrenzt werden kann. Dies ist jedoch für die meisten praktischen Fälle ausreichend. In Fig. 2 with Fig. 1 are the same parts with the same reference numerals provided, which only added an a is. 2, an acceptance limiting block 32 is provided, in which, for example, the maximum number of one to be accepted Coin is entered. In a table 34 the assignment of the coin values according to blocks 16a to 22a for acceptance limit 32, only one at a time predefined coin value can be limited in number. However, this is sufficient for most practical cases.

    In Fig. 3 entsprechen die Blöcke 16b bis 22b den Münzwertigkeiten, die vom Münzprüfer bzw. Münzgerät akzeptiert werden. Die Wertigkeitssignale gehen zum einen auf das Kreditwerk 12b, wo sie aufaddiert werden. Sie gehen zum anderen auf einen Block 36. In dem Block 36 wird zum Beispiel der Differenzbetrag eingespeichert, der bis zum Erreichen des Preises im Block 10b mit Münzwertigkeiten erzielt werden muß, die nicht begrenzt sind. Ist dieser Differenzbetrag erreicht, wird über die zum Kreditwerk 12b führende Wirkungslinie die Erzeugung eines Kreditsignals verhindert. Selbstverständlich muß auch die Annahme weiterer Münzen der begrenzten Münzwertigkeit durch ein entsprechendes Rückgabesignal verhindert werden. Wie oben bereits erläutert, kann der Differenzbetrag, der mindestens erreicht werden muß, zum Beispiel 3 DM sein, wenn der Preis 5 DM ist und die Anzahl der begrenzten 1-DM Münzen 2.3, blocks 16b to 22b correspond to the coin denominations, accepted by the coin validator or coin device become. The value signals go to the one Credit facility 12b, where they are added up. You go to others to a block 36. In block 36, for example the difference amount stored until reaching of the price in block 10b with coin denominations that are not limited. Is this difference is reached via the credit facility 12b leading line of action the generation of a credit signal prevented. Of course, the acceptance of others must also Coins of limited coin value by a corresponding one Return signal can be prevented. As above already explained, the difference, the minimum must be achieved, for example, 3 DM if the price is 5 DM and the number of limited 1 DM coins 2nd

    Alternativ kann im Speicherabschnitt 36 ein sogenannter Merker gesetzt werden, der feststellt, ob die Zahl der begrenzten Münzen pro Verkaufsvorgang gleich bzw. überschritten worden ist. Alternativ kann auch die Anzahl der nicht begrenzten Münzen pro Verkaufsvorgang festgestellt werden, um die Erzeugung eines Kreditsignals zuzulassen, wenn die Anzahl der nicht begrenzten Münzwertigkeiten die gespeicherte Anzahl erreicht.Alternatively, a so-called Flag is set, which determines whether the number of limited Coins equal or exceeded per sales transaction has been. Alternatively, the number of Unlimited coins per transaction found to allow the creation of a credit signal, if the number of unlimited coin denominations saved number reached.

    In dem Blockschaltbild nach Fig. 4 ist im Block 38 die vorgegebene Anzahl der erlaubten Annahme sowie die Münzwertigkeiten gespeichert, für die die Begrenzungsfunktion gelten soll. Bei den eingeworfenen Münzen werden in dem Block 38 nur diejenigen Münzwertigkeiten addiert, die begrenzt sind. Im Block 40 erfolgt die Differenzbildung zwischen dem Preis aus Block 10c und den aufaddierten begrenzten Münzwertigkeiten. Erreicht der Differenzbetrag einen bestimmten Mindestwert, muß die weitere Kreditbildung pro Verkaufsvorgang über nicht begrenzte Münzwertigkeiten erreicht werden, wie durch Block 42 repräsentiert.4 is in block 38 of specified number of accepted acceptances as well as the coin denominations saved for which the limiting function should apply. When the coins are thrown in the Block 38 only adds those coin denominations that are limited are. In block 40, the difference is formed between the price from block 10c and the added limited Coin denominations. Reaches the difference a certain minimum value, further credit formation per sales transaction via unlimited coin denominations can be achieved as represented by block 42.
