Die Erfindung wird anhand der Zeichnungen an einem Ausführungsbeispiel näher erläutert. Es zeigen: The invention is explained in more detail with reference to the drawings using an exemplary embodiment. Show it:

Fig. 1 eine Ansicht des Münzprüfers nach der Erfindung, teilweise im Schnitt, längs der Linie I—I nach Fig. 3, 1 is a view of the coin validator according to the invention, partly in section, along the line I-I of FIG. 3,

Fig. 2 eine Vorderansicht desselben in Richtung der Rollbewegung der Münzen, im Teilschnitt längs der Linie II-II nach Fig. 3, und Fig. 2 is a front view of the same in the direction of the rolling movement of the coins, in partial section along the line II-II of Fig. 3, and

Fig. 3 eine Seitenansicht in Richtung des Pfeils III in Fig. 1 und 2. 3 is a side view in the direction of arrow III in FIGS. 1 and 2.

Danach sind an einer etwas gegenüber der Senkrechten geneigten Gestellwand 1 eine Laufschiene 2, darüber auf der einen Seite ein zur Laufschiene 2 paralleles Führungslineal 3 und im Abstand darüber, auf der anderen Seite der Laufschiene 2, eine Ablenkschiene 7 befestigt. Die Laufschiene 2 ist in Bewegungsrichtung der Münzen M, also in Richtung des Pfeiles A nach Fig. 1 und 3, geneigt angeordnet, damit die Münzen M darauf abrollen können, und hat, wie in Fig. 2 gezeigt, eine etwas kleinere Breite als die Münze M. Thereafter, on a frame wall 1 slightly inclined to the vertical, a running rail 2, above which on one side a guide ruler 3 parallel to the running rail 2 and at a distance above it, on the other side of the running rail 2, a deflection rail 7 is fastened. The running rail 2 is inclined in the direction of movement of the coins M, that is to say in the direction of the arrow A according to FIGS. 1 and 3, so that the coins M can roll thereon, and, as shown in FIG. 2, has a somewhat smaller width than that Coin M.

Das Führungslineal 3 hat eine Anlagefläche 3b (Fig. 1) für die Münze M und eine Oberkante 3a (Fig. 2), liegt in einer Ausnehmung 16 der Gestellwand 1 und hintergreift mit seinen entsprechend abgebogenen Endabschnitten 4, wie in Fig. 1 The guide ruler 3 has a contact surface 3b (FIG. 1) for the coin M and an upper edge 3a (FIG. 2), lies in a recess 16 in the frame wall 1 and engages behind with its correspondingly bent end sections 4, as in FIG. 1

dargestellt, die die Ausnehmung 16 begrenzenden Bereiche der Gestellwand 1. Diese Endabschnitte 4 des Führungslineals 3 sind nach Fig. 3 rechteckförmig vergrössert und mit Langlöchern 5 zur Aufnahme von in der Gestellwand 1 sitzenden i Befestigungsschrauben 6 versehen. Mit Hilfe der Langlöcher 5 kann das Führungslineal 3 in einer einstellbaren Höhe derart über der Laufschiene 2 befestigt werden, dass sich seine Oberkante 3a etwas oberhalb des Mittelpunktes der auf der Laufschiene 2 abrollenden, zu prüfenden Münze befindet. ] Auf der dem Führungslineal 3 abgewandten Seite der Laufschiene 2 ist im Abstand über der Oberkante 3a des Führungslineals 3 die Ablenkschiene 7 in Form eines L-förmigen Teils angebracht, dessen langer, parallel zum Führungslineal 3 orientierter Schenkel 7d oberhalb der Ausnehmung 16 mit Hilfe zweier Schraubenpaare justierbar an der Gestellwand 1 befestigt ist. Der kurze, senkrecht zu der durch die Anlagefläche 3b des Führungslineals 3 gehenden Ebene orientierte Schenkel 7c, der um ein Mehrfaches der Münzdicke, im betrachteten Beispiel um das Drei- bis Vierfache der Münzdicke über der Oberkante i 3a des Führungslineals 3 liegt, bildet an seiner mit der zu prüfenden Münze M zusammenwirkenden Kante nach Fig. 1 eine Einlaufschräge 7a, deren Abstand zu der durch die Anlagefläche 3b des Führungslineals 3 gehenden Ebene in Rollrichtung der Münze von einem Anfangswert, welcher grösser als die Breite des Münzeinwurfschlitzes des Münzautomaten ist, auf einen der vorgegebenen maximalen Münzdicke d (Fig. 1) ent-, sprechenden Wert abnimmt; diese Einlauf schräge 7a geht in eine parallel zur erwähnten Anlagefläche 3b verlaufende Führungsfläche 7b über, die wenigstens ungefähr so lang wie die Umfangslänge der Münze ist und die eigentliche Münzdickenbegrenzung definiert. shown, the recesses 16 delimiting areas of the frame wall 1. These end portions 4 of the guide ruler 3 are enlarged according to FIG. 3 rectangular and provided with elongated holes 5 for receiving i fastening screws 6 seated in the frame wall 1. With the help of the elongated holes 5, the guide ruler 3 can be fastened at an adjustable height above the running rail 2 in such a way that its upper edge 3a is located somewhat above the center of the coin to be checked rolling on the running rail 2. ] On the side of the guide rail 3 facing away from the guide ruler 3, the deflection rail 7 is attached in the form of an L-shaped part at a distance above the upper edge 3a of the guide ruler 3, the long leg 7d thereof, oriented parallel to the guide ruler 3, above the recess 16 with the aid of two Screw pairs is adjustably attached to the frame wall 1. The short leg 7c, which is oriented perpendicular to the plane passing through the contact surface 3b of the guide ruler 3 and which lies above the upper edge i 3a of the guide ruler 3 by a multiple of the coin thickness, in the example considered three to four times the coin thickness, forms on it with the coin M to be tested edge according to FIG. 1, an entry slope 7a, the distance to the plane going through the contact surface 3b of the guide ruler 3 in the rolling direction of the coin from an initial value which is greater than the width of the coin slot of the coin machine, to one the predetermined maximum coin thickness d (Fig. 1) corresponding value decreases; this inclined run-in 7a merges into a guide surface 7b which runs parallel to the abovementioned contact surface 3b and which is at least approximately as long as the circumferential length of the coin and defines the actual coin thickness limitation.

Die beiden Schrauben 8 des oberen Schraubenpaares durchsetzen vertikal orientierte Langelöcher 13 in der Gestellwand 1 und sind in je eine Gewindehülse 9 eingeschraubt, die eine in einem Loch 14 der Ablenkschiene 7 sitzende Kehle 9b und einen sich daran anschliessenden Hülsenkopf 9a auf der anderen Ablenkschienenseite aufweist. Jedes Loch 14 erweitert sich zu einer seitlichen Öffnung 15, die so gross ist, dass bei der Montage die Gewindehülse 9 mit ihrem Kopf 9a durch die Öffnung 15 hindurchgesteckt und dann seitlich mitihrer Kehel 9b in das Loch 14 eingeschoben werden kann, dessen Durchmesser geringer als der Hülsenkopf 9a ist. Auf diese Weise ist die Ablenkschiene 7 in den Hülsenkehlen um einen kleinen Winkel kippbar aufgehängt. Die Justierung auf die vorgegebene maximale Münzdicke d erfolgt mit Hilfe der beiden Schrauben 10 und den die Schrauben umgebenden, zwischen der Gestellwand 1 und der Ablenkschiene 7 liegenden Schraubenfedern 11, welche die Ablenkschiene 7 in dem durch die jeweilige Schraubeneinstellung gegebenen maximalen Abstand von der Gestellwand 1 halten. Die Schrauben 10 sitzen in Langlöchern 12 der Ablenkschiene 7, so dass diese mit Hilfe der Langlochpaare 12 und 13 auch in der Höhe verstellbar ist. The two screws 8 of the upper pair of screws penetrate vertically oriented elongated holes 13 in the frame wall 1 and are each screwed into a threaded sleeve 9, which has a groove 9b seated in a hole 14 of the deflection rail 7 and a sleeve head 9a adjoining it on the other deflection rail side. Each hole 14 widens into a lateral opening 15 which is so large that during assembly the threaded sleeve 9 with its head 9a can be inserted through the opening 15 and then laterally inserted with its groove 9b into the hole 14, the diameter of which is less than is the sleeve head 9a. In this way, the deflection rail 7 is suspended tiltable by a small angle in the sleeve throats. The adjustment to the predetermined maximum coin thickness d is carried out with the aid of the two screws 10 and the coil springs 11 which surround the screws and which lie between the frame wall 1 and the deflection rail 7 and which the deflection rail 7 at the maximum distance from the frame wall 1 given by the respective screw setting hold. The screws 10 are seated in elongated holes 12 in the deflection rail 7, so that the height thereof can also be adjusted with the aid of the elongated hole pairs 12 and 13.

Die Höher.abmessung des Führungslineals 3 beträgt, zur Verringerung der Reibung mit der Münze, lediglich einen Bruchteil des Münzdurchmessers. Unmittelbar neben der Laufschiene 2 ist unterhalb des Führungslineals 3 eine die Laufschienenebene übersteigende untere Münzführungskante la vorgesehen, die von der Gestellwand 1 gebildet wird und das sichere Abrollen der Münze M auf der Laufschiene 2 gewährleistet. Der Raum auf der anderen Seite unmittelbar neben der Laufschiene 2, unterhalb der Ablenkschiene 7, bildet direkt die Einfallöffnung für den die ausgesonderten Münzen aufnehmenden und in den Münzrückgabebehälter des Münzautomaten führenden Münzauswurfkanal 18. Der ganze Münzprüfer ist, wie in Fig. 2 angedeutet, um einen kleinen Winkel von etwa 10° gegen die Senkrechte geneigt, so dass die auf der Laufschiene 2 abrollende To reduce friction with the coin, the higher dimension of the guide ruler 3 is only a fraction of the coin diameter. Immediately next to the running rail 2, a lower coin guiding edge la, which exceeds the running rail plane, is provided below the guide rail 3, which is formed by the frame wall 1 and ensures the safe rolling of the coin M on the running rail 2. The space on the other side, directly next to the running rail 2, below the deflection rail 7, directly forms the inlet opening for the coin ejection channel 18, which receives the separated coins and leads into the coin return container of the coin machine. The entire coin validator is, as indicated in FIG. 2, around a small angle of about 10 ° to the vertical, so that the rolling on the track 2

Münze unter der Wirkung der Schwerkraft leicht an der Anlagefläche 3b des Führungslineals 3 anliegt. Coin bears lightly against the contact surface 3b of the guide ruler 3 under the effect of gravity.

Eine Münze M, welche die vorgegebene maximale Dicke d nicht übersteigt, rollt auf der Laufschiene 2 an der Ablenkschiene 7 ungestört vorbei und gelangt am Ende der Laufschiene 2 zur weiteren Verarbeitung in den normalen Münzkanal 17, der z.B. zum folgenden Münzprüfer oder in die Kasse führt. Eine Münze, deren Dicke grösser als die vorgegebene maximale Dicke d ist oder die eine entsprechend starke Verbiegung aufweist, wird beim Abrollen auf der Laufschiene 2 durch die Ablenkschiene 7 um eine durch die Oberkante 3a des Führungslineals 3 gebildete Schwenkachse im Uhrzeigersinne nach Fig. 2 soweit gekippt, dass sie von der Laufschiene 2 abrutscht und direkt in den Münzauswurfkanal 18 fällt, wie in Fig. 2 für die gestrichelt dargestellte Münze M' angedeutet. Da die Länge der Führungsfläche 7b der Ablenkschiene 7 wenigstens ungefähr so gross wie die Umfangslänge der zu prüfenden Münze ist, A coin M, which does not exceed the predetermined maximum thickness d, rolls undisturbed on the guide rail 2 past the deflection rail 7 and arrives at the end of the guide rail 2 for further processing in the normal coin channel 17, which e.g. to the next coin validator or to the cash register. A coin, the thickness of which is greater than the predetermined maximum thickness d or which has a correspondingly strong deflection, is rolled as far as it rolls on the running rail 2 by the deflecting rail 7 about a pivot axis formed by the upper edge 3a of the guide ruler 3 in a clockwise direction according to FIG. 2 tilted that it slips off the running rail 2 and falls directly into the coin ejection channel 18, as indicated in FIG. 2 for the coin M 'shown in dashed lines. Since the length of the guide surface 7b of the deflection rail 7 is at least approximately as great as the circumferential length of the coin to be checked,

werden auch unregelmässig verbogene oder deformierte Münzen mit Sicherheit durch die Ablenkschiene 7 ausgeschieden. Damit das zur Ablenkung der zu dicken Münzen erforderliche Kippmoment möglichst klein ist, wird die Höhe der Oberkante 5 3a des Führungslineals 3 über der Laufschiene 2 vorzugsweise gleich dem Münzradius plus 5—10% des Münzdurchmessers gewählt. Auf diese Weise befindet sich der Mittelpunkt grösserer Münzen etwa 1 mm und der kleineren Münzen etwa 2-3 mm unterhalb der als Kippachse wirkenden Oberkante 3a io des Führungslineals 3. Diese Dimensionierungen garantieren gleichzeitig, dass eine korrekte Münze mit Sicherheit nicht infolge Kippens von der Laufschiene 2 abrutschen kann. irregularly bent or deformed coins are also reliably eliminated by the deflection rail 7. So that the tilting moment required to deflect the coins that are too thick is as small as possible, the height of the upper edge 5 3a of the guide ruler 3 above the running rail 2 is preferably chosen to be equal to the coin radius plus 5-10% of the coin diameter. In this way, the center point of larger coins is about 1 mm and the smaller coins about 2-3 mm below the upper edge 3a io of the guide ruler 3, which acts as a tilting axis. At the same time, these dimensions guarantee that a correct coin will certainly not result from tilting from the running rail 2 can slip.

Die Laufschiene 2, die Anlagefläche 3b und die die Einlaufschräge 7 a und die Führungsfläche 7b bildende Kante der i5 Ablenkschiene 7 sind vorzugsweise aus einem harten, abriebfesten und einen nur geringen Reibungswiderstand mit der Münze aufweisenden Material. The running rail 2, the contact surface 3b and the edge of the i5 deflecting rail 7 forming the run-in slope 7a and the guide surface 7b are preferably made of a hard, abrasion-resistant and low frictional material with the coin.

ke overhanging or bent coin when passing through the deflection rail is tilted by a pivot axis formed by the above-mentioned upper edge of the guide ruler to such an extent that it slips off the running rail and falls directly into the aforementioned channel.

In this way it is achieved that the coin validator is made up of only a few practically maintenance-free parts, between which the separated coins cannot get stuck, and that, without a special sack channel, the coins deflected by the deflection rail from the running rail directly into the next to it The slide opening of the coin channel leading to the coin return container can fall while the accepted coins roll on the slide rail to the end of the slide rail and then continue their intended path, for example in the following coin acceptor or in the cash register. Preferably, the distance of the deflection rail from the plane passing through the contact surface of the guide ruler for the purpose of setting the coin thickness limit and the height of the deflection rail and the guide ruler above the running rail can be adjustable. The width of the running rail is also expediently smaller than the coin thickness, and the distance between the upper edge of the guide ruler and the running rail is advantageously chosen such that it is equal to the coin radius plus 5-10% of the coin diameter; This means that this upper edge of the guide ruler is approximately 2-3 mm above the center of the coin for smaller coins and approximately 1 mm for larger coins. If, furthermore, the plane of the running rail is appropriately inclined with respect to the horizontal and correspondingly the lateral guide members with respect to the vertical by a small angle to the side having the guide ruler, it is achieved that a coin rolling on the running rail slightly under the effect of gravity of the contact surface of the guide ruler and, if it does not exceed the specified thickness, can safely roll on the runner up to the end of the coin validator, but in the event that it exceeds the specified thickness, it will certainly be tilted by the deflection rail around the upper edge of the guide ruler , wherein the distance between the Alenkschiene and the upper edge of the guide ruler acting as a coin pivot axis represents a lever arm length. The thickness of the coin inspection path defined by the beginning of the run-in slope of the deflection rail is of course expediently made somewhat larger than the thickness of the coin insertion slot of the coin machine.
