Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Sicherung von mit einer Prüfeinrichtung für eine Gut-/Schlechterkennung von Münzen oder Jetons versehene Automaten gegen betrügerische Handlungen durch Herausziehen einer eingeworfenen, an einem Faden befestigten Münze nach Beendigung des Prüfvorganges, bei der der Prüfeinrichtung eine in einen Durchlaufkanal eingreifende steuerbare Klappe nachgeordnet ist, die einen Annahmekanal für eine Gut-Münze kurzzeitig freigibt und eine Falsch-Münze in einen Rückgabekanal umlenkt.The invention relates to a device for securing with a test device for good / bad detection of coins or chips equipped with tokens against fraudulent acts by pulling out a thrown in, attached to a thread Coin after the end of the test process at the test facility a controllable flap engaging in a flow channel is subordinate, the acceptance channel for a good coin for a short time released and a false coin redirected into a return channel.

Die Zahl der münzbetätigten Automaten nimmt mit steigender Automatisierung immer mehr zu. Diese Automaten dienen zu Spielzwecken, als Verkaufsautomaten, zur Informationsvermittlung usw.. Bekanntlich werden immer wieder Versuche unternommen, münzbetätigte Automaten zu manipulieren, wodurch diese unter Verwendung von geringerwertigen, weniger oder gar keinen Münzen betätigt werden können. Eine Variante dieser Versuche sind die sogenannten Fadenmanipulationen. Hierbei wird an von einem Automaten angenommenen Münzen ein Faden angebracht, der er ermöglicht, die eingeworfenen Münzen wieder aus dem Automaten herauszuziehen. Bei ausreichender Fadenlänge und Kenntnis des Automatenaufbaues kann erreicht werden, daß eine solche Fadenmünze die Prüfeinrichtung durchläuft, dort geprüft und dann über eine steuerbare Klappe in einen Annahmekanal freigegeben wird, wobei die Fadenmünze erst anschließend wieder unter teilweiser Öffnung der den Durchlaufkanal sperrenden Klappe, was durch den Faden an der Münze bewirkt wird, wieder herausgezogen wird. Eine Öffnung der den Durchlaufkanal sperrenden Klappe, die in dieser Position eine in der Prüfeinrichtung als nicht zulässig erkannte Münze in einen Rückgabekanal umlenkt, ist beim Zurückziehen einer Fadenmünze besonders dann leicht möglich, wenn ein Doppel-Faden benutzt wird, dessen einer Fadenstrang avers und dessen anderer Fadenstrang revers mittig an der Münze befestigt ist, da ein solcher Doppel-Faden selbst dann die Klappe öffnet, wenn die Klappe mit einem Absatz im Durchlaufkanal zusammenwirkt.The number of coin-operated machines increases with increasing automation more and more. These machines are used for gaming purposes, as vending machines, for conveying information, etc. As is well known attempts are made again and again, coin-operated machines to manipulate, thereby using lower quality, fewer or no coins can be operated. A variant of these attempts are the so-called thread manipulations. Here, coins are accepted from a machine a thread attached, which enables it to the thrown in Pull coins out of the machine. With sufficient Thread length and knowledge of the machine structure can be achieved that such a thread coin passes through the test device, checked there and then via a controllable flap into an acceptance channel is released, the thread coin only afterwards again with partial opening of the passageway Pull out the flap, which is caused by the thread on the coin becomes. An opening that blocks the flow channel Flap, which in this position is one in the test facility the recognized coin is diverted into a return channel particularly easy when withdrawing a thread coin if a double thread is used, one strand of which is avers and the other strand of thread reversely attached to the center of the coin is because such a double thread opens the flap even then, if the flap interacts with a shoulder in the flow channel.

Aus der DE 32 26 737 A1 ist es bekannt, zur Verhinderung von Manipulationen an Münzautomaten eine Pendelklappe am Einwurfschacht vorzusehen, die im Fall einer Fadenmünze den Faden einklemmt. Dadurch wird der Faden zusammen mit der Münze stark abgebremst, und die Durchlaufgeschwindigkeit der Fadenmünze ist gegenüber der Geschwindigkeit einer normalen Münze stark verringert. Eine solche Fadenmünze wird dann in der Prüfeinrichtung als Falschmünze erkannt.From DE 32 26 737 A1 it is known to prevent tampering a pendulum flap on the slot in coin operated machines provide that the thread jams in the case of a thread coin. Thereby the thread is braked together with the coin, and the throughput speed of the thread coin is compared to the speed a normal coin greatly reduced. Such Thread coin is then recognized in the test device as a false coin.

Weiterhin offenbar die CH-A-680 399 eine Münzeingabevorrichtung für Münzautomaten, bei der unmittelbar nach der Münzeingabe vor einer als seitlich verschiebbarer Schieber ausgebildeten Klappe und vor einer Münzprüfeinheit ein Münzdetektor angeordnet ist, unterhalb dessen sich eine weitere Klappe befindet. Der Münzdetektor, der die beiden Klappen steuert, erkennt, ob eine an einem Faden befestigte Münze vorhanden ist. Die eigentliche Münzprüfung erfolgt durch die Münzprüfeinheit, wenn eine Münze nach Erkennung durch den Münzdetektor in den Münzkanal gelangt ist und der Durchgang zum Münzprüfer ermöglicht wird. Sollte der Betrüger jedoch den Münzdetektor durch simulierten Einwurf einer weiteren Münze dazu bringen, die dem Münzkanal zugeordnete Klappe zu öffnen, so gibt die Klappe den Münzkanal für den Faden und die Münze frei. Furthermore, CH-A-680 399 apparently discloses a coin input device for coin machines, at the immediately after entering the coin a flap designed as a laterally displaceable slide and a coin detector is arranged in front of a coin checking unit, below which is another flap. The coin detector, who controls the two flaps recognizes whether one is on a thread fortified coin is present. The actual coin check is carried out by the coin validation unit when a coin is recognized has entered the coin channel through the coin detector and the passage to the coin validator. However, the fraudster should the coin detector by simulating the insertion of another coin get the flap assigned to the coin channel to open, see above the flap releases the coin channel for the thread and the coin.

Ferner zeigt die DE-C-41 17 096 eine Einrichtung zur Erkennung einer mit einem Faden versehenen Münze in einem Münzkanal, wobei eine den Münzkanal in ihrer Ruhelage verschließende Pendelklappe vorgesehen ist. Die Pendelklappe weist mehrere, quer zum Münzkanal verlaufende Rippen auf, die in der Ruhelage der Pendelklappe in entsprechende Nuten in der Seitenwand des Münzkanals eintauchen. Des weiteren besitzt die Pendelklappe an ihrem unteren Ende eine Schrägfläche, wobei eine auf die Schrägfläche auftreffende Münze durch ihr Gewicht die Pendelklappe derart verschwenkt, daß die Münze durch den Münzkanal gleiten kann.Furthermore, DE-C-41 17 096 shows a device for recognizing a with a thread-provided coin in a coin channel, one pendulum flap closing the coin channel in its rest position is provided. The pendulum flap has several, transverse to the coin channel running ribs on the in the rest position of the swing flap in Immerse the corresponding grooves in the side wall of the coin channel. Furthermore, the swing flap has one at its lower end Inclined surface, a coin hitting the inclined surface by their weight, the swing flap is pivoted so that the Coin can slide through the coin channel.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die mit einfachen kostengünstigen Mitteln Fadenmanipulationen an einem münzbetätigten Automaten verhindert.The invention has for its object a device to create the kind mentioned above with simple inexpensive Using thread manipulation on a coin-operated machine prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Klappe winkelförmig ausgebildet ist, wobei der in Querrichtung des Durchlaufkanals verlaufende Schenkel der Klappe stirnseitig mit kammartigen Schlitzen versehen ist, in die der Faden einer in den Annahmekanal gelangten Fadenmünze einfällt.This object is achieved in that the flap is formed angular, the in the transverse direction of the flow channel extending legs of the flap on the face with comb-like Slots are provided, into which the thread is one in the acceptance channel thread coin occurs.

Durch diese Maßnahme wird mit Sicherheit ein Zurückziehen der Fadenmünze aus dem Annahmekanal in die Prüfeinrichtung für die Gut/SChlechterkennung von Münzen ausgeschlossen, da beim Zurückziehen der Fadenmünze der Faden oder ggfls. zumindest ein Fadenstrang eines Doppel-Fadens in einen der Schlitze der Klappe gelangt, wodurch beim Zurückziehungsvorgang die Fadenmünze an der Unterseite der Klappe zur Anlage kommt und damit ein Öffnen der Klappe durch die Fadenmünze nicht mehr möglich ist. Bei entsprechender Gewaltanwendung reißt der Faden oder löst sich an seiner Befestigungsstelle an der Münze, wodurch die Münze in den Annahmekanal fällt und der Faden aus der Prüfeinrichtung herausgezogen werden kann. With this measure, a withdrawal of the thread coin is certain from the acceptance channel to the test facility for good / bad detection excluded from coins because when withdrawing the thread of the thread or if necessary. at least one strand of thread Double thread enters one of the slits in the flap, causing the thread coin on the underside during the withdrawal process the flap comes into contact and the flap opens the thread coin is no longer possible. With appropriate use of force the thread breaks or loosens at its attachment point on the coin, causing the coin to fall into the acceptance channel and the thread can be pulled out of the test device.

Da weiterhin viele Prüfeinrichtungen mit einer verschwenkbaren Klappe zur wahlweisen Beförderung einer Münze in einen Annahmekanal oder in einen Rückgabekanal ausgerüstet sind, besteht die kostengünstige Möglichkeit derartiger Prüfeirnichtungen mit einer mit kannartigen Schlitzen versehenen, winkelförmigen Klappe nachzurüsten.Since many test facilities continue with a swiveling Flap for the optional transport of a coin into an acceptance channel or are equipped in a return channel, there is the inexpensive Possibility of such test setups with a retrofitted with can-shaped slots, angled flap.

Bei einer vorteilhaften Ausgestaltung der Erfindung ist der in Längsrichtung des Durchlaufkanals verlaufende Schenkel der mittels eines Elektromagneten und einer Feder zwischen einer Sperrstellung und einer Freigabestellung des Durchlaufkanals bewegbaren Klappe endseitig auf einer Achse gelagert. So ergibt sich insgesamt eine konstruktiv einfach aufgebaute erfindungsgemäße Vorrichtung.In an advantageous embodiment of the invention, the in Leg extending in the longitudinal direction of the flow channel of the means of an electromagnet and a spring between a locked position and a release position of the flap movable flap supported at one end on an axle. So there is a total Device of simple construction according to the invention.

Um ein zuverläsisges Eingreifen des Fadens der Fadenmünze in die Schlitze der Klappe zu erreichen, sind nach einer vorteilhaften Weiterbildung der Erfindung die neben den Schlitzen vorhandenen Stege der Klappe stirnseitig spitz oder entsprechend abgerundet ausgeführt. Zweckmäßigerweise sind hierbei die Schlitze in der Klappe in Draufsicht+ rechteckförmig oder dreieckförmig ausgebildet.In order for the thread of the thread coin to engage reliably in the Reaching slots in the flap are advantageous Development of the invention in addition to Slits existing webs of the flap pointed on the front or rounded off accordingly. Conveniently are the slots in the flap in plan view + rectangular or triangular.

Der der Erfindung zugrundeliegende Gedanke wird in der nachfolgenden Beschreibung anhand zweier Ausführungsbeispiele, die in der Zeichnung dargestellt sind, näher erläutert. Es zeigt:

Ein einer nichtdargestellten Prüfeinrichtung für Münzen eines münzbetätigten Automaten nachgeordneter Durchlaufkanal 1 geht in seinem unteren Bereich in eine beidseitig sich des Durchlaufkanals 1 erstreckende Erweiterung 2 über, in die eine den Durchlaufkanal 1 wahlweise freigebende oder verschließende schwenkbewegliche Klappe 3 eingesetzt ist. Die Klappe 3 ist über einen nichtdargestellten Elektromotor sowie eine Feder in eine Öffnungsstellung und eine Schließstellung für den Durchlaufkanal 1 verschwenkbar, was durch den Doppel-Pfeil 4 angedeutet ist. Unterhalb der Klappe 3 befindet sich ein Annahmekanal 5 für von der Prüfeinrichtung als zulässig erkannte Gut-Münzen, während oberhalb der Klappe von dem Durchlaufkanal 1 ein Rückgabekanal 6 für von der Prüfeinrichtung als nicht zulässig erkannte Falsch-Münzen abgeht. Die Klappe 3 wird ständig in ihrer Schließstellung gehalten und wird nur beim Erkennen einer Gut-Münze durch die Prüfeinrichtung kurzzeitig in die Öffnungsstellung überführt, um die Gut-Münze in den Annahmekanal 5 fallenzulassen. Anschließend wird die Klappe 3 sofort wieder in ihre Schließstellung gebracht. Dieser Vorgang spielt sich auch dann ab, wenn eine an einem Faden befestigte Münze 7 in den Annahmekanal gelangt. Anstelle eines einzelnen Fadens kann auch ein Doppel-Faden 8 benutzt werden, dessen einer Fadenstrang 9 an der Rückseite und dessen anderer Fadenstrang 10 an der Vorderseite der Münze 7 befestigt ist.One of a testing device for coins, not shown coin-operated automatic machine downstream passageway 1 goes in its lower area in a mutually facing Flow channel 1 extending extension 2 over, in the a flow channel 1 optionally releasing or closing pivotable flap 3 is used. The Flap 3 is via an electric motor, not shown and a spring in an open position and a closed position pivotable for the flow channel 1, what by the double arrow 4 is indicated. Below the flap 3 there is an acceptance channel 5 for from the test facility Good coins recognized as permissible, while above the Flap from the flow channel 1, a return channel 6 for from counterfeit coins recognized as not permitted by the testing facility goes off. The flap 3 is constantly in its closed position is held and is only recognized when a good coin is recognized through the test device into the open position for a short time transferred to drop the good coin into acceptance channel 5. Then the flap 3 is immediately in again brought their closed position. This process takes place even if a coin attached to a thread 7 in reaches the acceptance channel. Instead of a single thread a double thread 8 can also be used, one of which Thread strand 9 on the back and its other thread strand 10 is attached to the front of the coin 7.

Die winkelförmig ausgebildete Klappe 3 weist einen in Längsrichtung des Durchlaufkanals 1 verlaufenden Schenkel 11 und einen in Querrichtung des Durchgangskanals 1 verlaufenden Schenkel 12 auf. Der Schenkel 11 ist endseitig auf einer Achse 13 gelagert. Der den Durchlaufkanal 1 in der Schließstellung der Klappe 3 sperrende Schenkel 12 ist von seiner Vorderseite her mit kammartig nebeneinanderliegenden Schlitzen 14 versehen, die in der Draufsicht rechteckförmig oder dreieckförmig ausgebildet sein können. Die neben den Schlitzen 14 in dem Schenkel 12 ausgebildeten Stege 15 sind jeweils stirnseitig spitz oder entsprechend abgerundet ausgeführt, damit der Faden oder Doppel-Faden 8 einer den Annahmekanal 5 erreichten Fadenmünze 7 stets in einen der Schlitze 14 hineingleitet. Wird nun versucht, die in dem Annahmekanal 5 befindliche Fadenmünze 7 zurückzuziehen, um in der Prüfeinrichtung ein weiteres Annahmesignal zu erzeugen, dann wird dies dadurch verhindert, daß die Fadenmünze aufgrund der Führung des Fadens 8 durch einen der Schlitze 14 an der Unterseite des Schenkels 12 zur Anlage kommt, wodurch bei einer weiteren Zugbewegung des Fadens 8 keine Öffnungsbewegung der Klappe 3 erfolgt. Sonach kann mittels der Fadenmünze kein weiteres Annahmesignal in der Prüfeinrichtung erzeugt werden.The angular flap 3 has one in the longitudinal direction of the flow channel 1 extending leg 11 and a extending in the transverse direction of the through channel 1 Leg 12 on. The leg 11 is on one end Axis 13 mounted. The flow channel 1 in the closed position the flap 3 blocking leg 12 is from his Front side with comb-like slits 14 provided, which are rectangular or in plan view can be triangular. The next to the Slots 14 are formed in the leg 12 webs 15 each pointed or rounded at the front, so that the thread or double thread 8 one the Acceptance channel 5 always reached thread coin 7 in one of the Slits 14 slide into it. Trying now in the Acceptance channel 5 located thread coin 7 to withdraw generate a further acceptance signal in the test facility, then this is prevented by the thread coin due to the guidance of the thread 8 through one of the slots 14 comes to rest on the underside of the leg 12, whereby with a further pulling movement of the thread 8 none Opening movement of the flap 3 takes place. So you can use the thread coin no further acceptance signal in the test facility be generated.
