Description

Die Erfindung betrifft ein Münzzählwerk mit den Markmalen im Oberbegriff des Anspruchs 1.The invention relates to a coin counter with the features in the preamble of claim 1.

Ein derartiges Münzzählwerk ist in der DE-PS 852 313 beschrieben. Bei der DE-PS 852 313 wirkt der Auslösehebel insofern ungünstig auf den zugeordneten Rad-Getriebezug, als er bei Störungen ein unerwünschtes Auflaufen eines Kredits nicht ausschließt. Darüber hinaus ist nicht sichergestellt, daß der Energiespeicher bei jeder Betätigung des Selbstverkäufers gleich aufgezogen ist. Außerdem ist die der Preiseinstellung dienende Steuereinrichtung unübersichtlich.Such a coin counter is described in DE-PS 852 313. In DE-PS 852 313, the release lever has an unfavorable effect on the associated wheel gear train in that it does not rule out an undesirable accumulation of a loan in the event of malfunctions. In addition, it is not ensured that the energy store is drawn up the same every time the self-seller is actuated. In addition, the control device used to set the price is confusing.

In der DE-AS 12 82 348 ist ein Münzzählwerk für Selbstverkäufer beschrieben, bei dem zwei gegenläufig drehbare Zählsegmente vorgesehen sind. Dementsprechend lassen sich primär nur zwei Münzwerte erfassen. Nur wenn eine doppelwertige Münze über einen zweiten Auslösehebel das Zählsegment um einen weiteren Schritt fortschaltet, lassen sich drei unterschiedliche Münzwerte summieren. Eine solche Doppelschaltung ist ungünstig. Die Zählsegmente sind mittels einer Feder gegeneinander vorgespannt. Sie werden durch ein Rückstellglied in ihre Ausgangsstellung zurückgedreht. Von den Auslösehebeln betätigte Sperrklinken stellen ein nur schrittweises Fortschalten der Zählsegmente sicher.DE-AS 12 82 348 describes a coin counter for self-sellers in which two counter segments which can be rotated in opposite directions are provided. Accordingly, only two coin values can be recorded. Only when a double-value coin advances the counting segment by a further step via a second trigger can three different coin values be added up. Such a double circuit is unfavorable. The counting segments are biased against each other by means of a spring. They are turned back to their starting position by a reset element. Pawls actuated by the release levers ensure that the counting segments are only gradually advanced.

Aufgabe der Erfindung ist es, ein Münzzählwerk mit den Merkmalen im Oberbegriff des Anspruchs 1 un schaffen mit dem eine exakte, störungsfreie Fortschaltung der Summenwelle zu einem einstellbaren Verkaufspreis erreicht wird, wobei möglich Störungsursachen beim Münzeinlauf, beim Energiespeicherablauf und bei der Kreditierung beseitigt sind.The object of the invention is to provide a coin counter with the features in the preamble of claim 1 and with which an exact, trouble-free advancement of the sum wave is achieved at an adjustable retail price, with possible causes of malfunction in the coin entry, in the energy storage process and in the credit are eliminated.

Erfindungsgemäß ist die genannte Aufgabe bei einem Münzzählwerk nach dem Oberbegriff des Anspruches 1 durch dessen kennzeichnende Merkmale gelöst.According to the invention, the above object is achieved in a coin counter according to the preamble of claim 1 by its characterizing features.

Bei der Erfindung wird der mechanische Energiespeicher bei jeder Betätigung der Ausgabeeinrichtung aufgezogen. Es steht also für jeden Verkaufsvorgang die gleiche Speicherladung zur Verfügung. Dies ist für ein gleichmäßiges Ablaufen der Getriebezüge günstig. Andererseits ist dadurch ein kompakter Aufbau des Energiespeichers möglich. Da der Energiespeicher bei jedem Verkaufsvorgang von selbst geladen wird, braucht er im Prinzip nur so stark ausgelegt zu werden, daß er eine für die Summierung des höchsten Verkaufspreises hinreichende Ladung enthält.In the invention, the mechanical energy store is opened each time the output device is actuated. The same storage charge is therefore available for every sales transaction. This is favorable for the gear trains to run smoothly. On the other hand, this enables a compact construction of the energy store. Since the energy store is charged by itself with every sales transaction, in principle it only needs to be designed so strongly that it contains a charge sufficient for the summation of the highest sales price.

Außeredem ist erreicht, daß eine Münze jedes Münzwertes über den betreffenden Auslösehebel das zugeordnete Hemmrad mittels des jeweiligen Hemmankers zwangsweise nur um einen einzigen Schritt weiterschaltet. Die entsprechend den Münzwerten unterschiedliche Verstellung des Zählrades wird durch die genannte Übersetzung erreicht. Bei entsprechender Ubersetzung der Zahnräder der Getriebezüge lassen sich gleiche Hemmräder verwenden. Es kann die Übersetzung auch durch Hemmräder mit unterschiedlicher Zahnzahl erreicht werden. Die an der Summenwelle verstellbaren Nockenscheiben lassen sich auf die jeweiligen Verkaufspreise einstellen. Die Anzeigewalze zeigt den aufgelaufenen Kredit an.In addition, it is achieved that a coin of each coin value forcibly advances the assigned escapement wheel by means of the respective escapement lever by only a single step. The different adjustment of the counter wheel according to the coin values is achieved by the above-mentioned translation. With corresponding gear ratios of the gear trains, the same escapement wheels can be used. The gear ratio can also be achieved by means of escapement wheels with different numbers of teeth. The cam disks adjustable on the total shaft can be adjusted to the respective sales prices. The indicator roller shows the accumulated loan.

In Ausgestaltung der Erfindung ist die Summenwelle bzw. das Zählrad zur Rückstellung von den Zahnrädern bei einer Betätigung der Ausgabeeinrichtung entkuppelt. In Weiterbildung ist zur einfachen Rückstellung der Summenwelle am Zählrad eine Herzkurve vorgesehen, an der ein Rückstellhebel anliegt.In an embodiment of the invention, the sum shaft or the counting wheel is uncoupled from the gearwheels for resetting when the output device is actuated. In a further development, a heart curve is provided on the counter wheel for easy resetting of the sum wave, on which a reset lever rests.

Besonders einfach ist der Aufbau, wenn nur ein, den Getriebezügen gemeinsames Zahnrad an dem Zählrad angreift.The construction is particularly simple if only one gearwheel common to the gear trains acts on the counting wheel.

Es kann ein einziger machanischer Energiespeicher vorgesehen sein, der auf die Hemmräder bzw. Zahnräder sämtlicher Getriebezüge einwirkt. Es kann jedoch auch für jeden Getriebezug ein eigener Energiespeicher vorgesehen sein.A single mechanical energy store can be provided, which acts on the escapement wheels or gear wheels of all gear trains. However, a separate energy store can also be provided for each gear train.

In vorteilhafter Ausgestaltung der Erfindung betätigt der Auslösehebel mit einem im Vergleich zu seiner Länge kurzen Helelarm den Hemmanker an einem freien Ende und am Hemmanker greift eine Feder an, die den Hemmanker und über sein freies Ende den Auslösehebel zurückstellt. Es ist damit eine sichere Halbschritt-Weiterschaltung des jeweiligen Hemmrads erreicht.In an advantageous embodiment of the invention, the release lever actuates the inhibiting armature at a free end with a short helelarm in comparison to its length, and a spring engages on the inhibiting armature, which resets the inhibiting armature and, via its free end, the release lever. A safe half-step advance of the respective escapement wheel is thus achieved.

Das beschriebene Münzzählwerk kann nicht nur bei rein mechanischen Selbstverkäufern eingesetzt werden. Es lässt sich auch mit Vorteile bei solchen Selbstverkäufern verwenden, die mit elektromechanischen Ausgabeeinrichtungen arbeiten, da das beschriebene Münzzählwerk weniger aufwendig ist, als elektromechanische Münzzählwerke.The coin counter described can not only be used by purely mechanical vendors. It can also be used with advantages in such self-sellers who work with electromechanical dispensers, since the coin counter described is less complex than electromechanical coin counters.

Ein Ausführungsbeispiel der Erfindung ergibt sich aus der folgenden Beschreibung. Die Zeichnung zeigt ein mechanisches Münzzählwerk schematisch.An embodiment of the invention results from the following description. The drawing shows a mechanical coin counter schematically.

Die Überholkupplung kann hierfür mit axialen, sägezahnförmigen Verzahnungen versehen sein. Das Triebrad 18 steht unter der Kraft eines Energiespeichers, welcher beispielsweise von einer Zahnstange 22 gebildet ist, die von einer Feder 23 vorgespannt ist.An escapement wheel 16 is assigned to the escapement 9.

Auf der Summenwelle 39 ist eine Anzeigewalze 43 befestigt, die an ihrem Außenumfang mit einer Beschriftung versehen ist, welche durch ein Fenster 44 der Vorderfront 45 des Selbstverkäufers abzulesen ist.A display roller 43 is attached to the sum shaft 39 and is provided on its outer circumference with a label which can be read through a window 44 in the front 45 of the self-seller.

Außerdem sitzen auf der Summenwelle 39 Nockenscheiben 46. Diese sind gegenüber der Summenwelle 39 hinsichtlich der Winkellage ihrer Nocken 47 verstellbar. Jeder Nockenscheibe 46 ist ein Abtasthebel 48 zugeordnet. Die Abtasthebel 48 steuern die Freigabe von Ausgabeeinrichtungen des Selbstverkäufers.In addition, 39 cam disks 46 sit on the sum shaft. These are adjustable relative to the sum shaft 39 with regard to the angular position of their cams 47. A scanning lever 48 is assigned to each cam disk 46. The sensing levers 48 control the release of self-seller dispensers.

Zum Aufziehen der Energiespeicher bzw. Zahnstangen 22, 29, 36 bzw. dem Vorspannen der betreffenden Federn 23, 30, 37 ist ein Aufzugsschieber 49 vorgesehen, welcher beim Betätigen einer der ausgabeeinrichtungen des Selbstverkäufers die Energiespeicher lädt. Außerdem sind mit den Ausgabeeinrichtungen des Selbstverkäufers der Rückstellhebel 41 und der Kupplungshebel 42 gekoppelt. Bei mechanischen Selbstverkäufern kann die Ankopplung des Rückstellhebels 41, des Kupplungshebels 42, des Aufzugsschiebers 49 und des Abtasthebels 48 mit entsprechenden Hebelübersetzungen erfolgen. Bei elektromechanischen Selbstverkäufern können zur Betätigung der genannten Glieder elektromagnetische Antriebsmittel vorgesehen sein.To open the energy store or racks 22, 29, 36 or to bias the relevant springs 23, 30, 37, an elevator slide 49 is provided, which loads the energy store when one of the dispensing devices of the self-seller is actuated. In addition, the reset lever 41 and the clutch lever 42 are coupled to the output devices of the self-seller. In mechanical vendors, the reset lever 41, the clutch lever 42, the elevator slide 49 and the scanning lever 48 can be coupled with corresponding lever ratios. In the case of electromechanical vendors, electromagnetic drive means can be provided for actuating the links mentioned.

Geht man beispielsweise davon aus, daß Auslösehebel für 1,- DM-, 2,- DM- und 5,- DM-Münzen vorgesehen sind, dann werden beispielsweise Räder mit folgenden Zahnzahlen vorgesehen:

Figure imgb0001
If one assumes, for example, that release levers are provided for 1, - DM, 2, - DM and 5, - DM coins, then for example wheels with the following number of teeth are provided:
Figure imgb0001

Ersichtlich stehen dabei die Übersetzungen in den Getriebezügen in dem Verhältnis 1:2:5.The ratios in the gear trains are clearly in the ratio 1: 2: 5.

Die Wirkungsweise des beschriebenen Münzzählwerks ist etwa folgende:

  • Vor einem Verkaufsvorgang steht das Zählrad 38 in der Nullstellung. Durch das Fenster 44 ist an der Anzeigewalze 43 die Zahl Null abzulesen. Die Energiespeicher 22, 29, 36 sind aufgezogen. Jede Nockenscheibe 46 ist auf einen Verkaufspreis eingestellt.
The operation of the coin counter described is approximately as follows:
  • Before a sales transaction, the counter wheel 38 is in the zero position. The number zero can be read off the display roller 43 through the window 44. The energy stores 22, 29, 36 are mounted. Each cam 46 is set at a retail price.

Wird jetzt eine 1-, DM-Münze eingeworfen, dann gelangt diese über den nicht näher dargestellten Münzprüfer in den für die 1-, NM-Münzen vorgesehenen Münzschacht 3 und drückt dort den betreffenden Auslösehebel 1 nach unten, der mit seinem kurzen Hebelarm 7 dadurch das freie Ende 8 des Hemmankers 9 so verschwenkt, daß dessen einer Ankerhaken 14 außer Eingriff von dem Hemmrad 16 kommt und sein anderer Ankerhaken 15 in das Hemmrad 16 eingreift. Dabei führt das Hemmrad 16 einen Schritt um eine halbe Zahnteilung unter der Kraft der Zahnstange 22 durch. Sobald die Münze den Auslösehebel 1 verlässt, wird dieser unter der Kraft der Zugfeder 13 zurückgestellt. Gleichzeitig wird der Hemmanker 9 in seine Ausgangsstellung zurückgeschwenkt, wobei das Hemmrad 16 nochmals um eine halbe Zahnteilung gedreht wird. Insgesamt dreht sich also das Hemmrad 16 beim Einwurf einer Münze um einen Zahn. Entsprechend wird über die Überholkupplung 19 und das Zahnrad 21 das Zählrad 38 entsprechend gedreht. Im Fenster 44 erscheint die Beschriftung "1,-" der Anzeigewalze 43. Über die Summenwelle 39 sind auch die Nockenscheiben 46 um einen Schritt gedreht.If a 1, DM coin is now inserted, it passes through the coin validator (not shown in more detail) into the coin slot 3 provided for the 1, NM coins and there presses the relevant release lever 1, which with its short lever arm 7 thereby the free end 8 of the escapement 9 is pivoted such that one of the anchoring hooks 14 disengages from the escapement wheel 16 and its other anchoring hook 15 engages in the escapement wheel 16. The escapement wheel 16 performs a step by half a tooth pitch under the force of the rack 22. As soon as the coin leaves the release lever 1, it is reset under the force of the tension spring 13. At the same time, the escapement armature 9 is pivoted back into its starting position, the escapement wheel 16 being rotated again by half a tooth pitch. Overall, the escapement wheel 16 rotates around a tooth when a coin is inserted. Correspondingly, the counting wheel 38 is rotated accordingly via the overrunning clutch 19 and the toothed wheel 21. The appears in window 44 Inscription "1, -" of the display roller 43. Via the sum shaft 39, the cam disks 46 are also rotated by one step.

Beim Antrieb des Zahnrads 21 über das Hemmrad 16 halten die Überholkupplungen 28 und 35 die anderen Hemmräder 24, 31 entkuppelt.When driving the gear wheel 21 via the escapement wheel 16, the overrunning clutches 28 and 35 keep the other escapement wheels 24, 31 disengaged.

Werden wietere 1,- DM-Münzen eingeworfen, dann wiederholen sich die beschriebenen Vorgänge. Die Anzeigewalze 43 zeigt beispielsweise nach dem Einwurf von drei 1,- DM-Münzen "3,-" an. Ist eine der Nockenscheiben 46 so eingestellt, daß der Verkaufspreis 3,- DM beträgt, dann rastet der betreffende Abtasthebel 48 ein und gibt die zugeordnete Ausgabeeinrichtung zur Warenentnahme frei.If another 1, - DM coins are inserted, the described processes are repeated. The display roller 43 shows, for example, "3" after three DM coins have been inserted. If one of the cam disks 46 is set so that the sales price is DM 3, then the relevant scanning lever 48 engages and releases the assigned dispensing device for the removal of goods.

Wird eine 2,- DM-Münze eingeworfen, dann wird das Hemmrad 24 in der beim Hemmrad 16 beschriebenen Weise durch den Hemmanker 10 bzw. den zugeordneten Auslösehebel 1 insgesamt um eine Zahnteilung bewegt. Das Hemmrad 24 steht dabei unter der Kraft der Zahnstange 29 bzw. der Feder 30. Über das Zahnrad 27 wird das Zahnrad 20 und damit auch das Zahnrad 21 gedreht. Aufgrund der beschriebenen Übersetzung wird das Zählrad 38 dabei um einen Winkel verschwenkt, der doppelt so groß ist wie bei einem Antrieb durch das Hemmrad 16. Bei einem Antrieb über den Getriebezug 10, 24, 28, 20, 21 entkuppeln die Überholkupplungen 19 und 35 die anderen Hemmräder 16, 31.If a DM 2 coin is inserted, the escapement wheel 24 is moved in the manner described for escapement wheel 16 by the escapement 10 or the associated release lever 1 by one tooth pitch overall. The escapement wheel 24 is under the force of the toothed rack 29 or the spring 30. The toothed wheel 20 and thus also the toothed wheel 21 are rotated via the toothed wheel 27. Due to the translation described, the counting wheel 38 is pivoted through an angle that is twice as large as when driven by the escapement wheel 16. When driven by the gear train 10, 24, 28, 20, 21, the overrunning clutches 19 and 35 decouple them other escapement wheels 16, 31.

Entsprechendes gilt für den Getriebezug 11, 31, 33, 34, 35, 20, 21, der durch eine 5,- DM-Münze ausgelöst wird. Beim Einwurf einer 5,-DM-Münze wird das Zählrad 38 um gegenüber einem Antrieb über das Hemmrad 16 fünffachen Betrag degreht. An der Anzeigewalze 43 ist durch das Fenster 44 jeweils die Summe der im Zuge eines Kaufvorgangs eingeworfenen Münzen abzulesen.The same applies to the gear train 11, 31, 33, 34, 35, 20, 21, which is triggered by a 5, - DM coin. When a 5 DM coin is inserted, the counting wheel 38 is rotated five times as much as a drive via the escapement wheel 16. The sum of the coins inserted in the course of a purchase process can be read through the window 44 on the display roller 43.

Ist über einen der Abtasthebel 48 eine Warenausgabe freigegeben, dann kann eine Rückstellung des Münzzählwerks erfolgen. Es wird hierfür der Kupplungshebel 42 ver- . schwenkt, wodurch das Zählrad 38 vom Zahnrad 21 ausgerückt wird. Der Rückstellhebel 41, der sonst nicht an der Herzkurve 40 anliegt, drückt jetzt gegen diese, so daß die Anzeigewalze 43 und die Nockenscheiben 46 über die Summenwelle 39 in ihre Nullstellung gebracht werden. Die den einzelnen Getriebezügen zugeordneten Energiespeicher 22, 23; 29, 30; 36, 37 werden mittels des Aufzugsschiebers 49 gespannt. Die Zahnstangen 22, 29, 36 sind so ausgebildet und gelagert, daß sie bei der Aufzugsbewegung von den entsprechenden Triebrädern 18, 25, 32 entkuppelt sind. Der Aufzugsschieber 49 lässt sich ebenso wie der Kupplungshebel 42 und der Rückstellhebel 41 über die Ausgabeeinrichtung des Selbstverkäufers antreiben. Es ist jedoch auch möglich zum Antrieb des Rückstellhebels 41, des Kupplungshebels 42 und des Aufzugsschiebers 49 einen vom Benutzer zu bedienenden Griff oder elektromechanische Mittel vorzusehen.If a goods issue is released via one of the scanning levers 48, the coin counter can be reset. For this purpose, the clutch lever 42 is used. pivots, whereby the counter gear 38 is disengaged from the gear 21. The reset lever 41, which otherwise does not rest on the heart curve 40, now presses against it, so that the indicator roller 43 and the cam disks 46 are brought into their zero position via the sum shaft 39. The energy stores 22, 23; 29, 30; 36, 37 are tensioned by means of the elevator slide 49. The racks 22, 29, 36 are designed and mounted such that they are uncoupled from the corresponding drive wheels 18, 25, 32 during the elevator movement. The elevator slide 49, like the clutch lever 42 and the reset lever 41, can be driven via the dispenser of the self-seller. However, it is also possible to provide a handle to be operated by the user or electromechanical means for driving the reset lever 41, the clutch lever 42 and the elevator slide 49.

Es ist nicht erforderlich, daß das Hemmrad 24 eine andere Zahnzahl aufweist, als die übrigen Hemmräder 16 und 31. Es kommt lediglich darauf an, bei einer Hin- und Herbewegung eines der Hemmanker 9, 10, 11 die damit freigegebene Drehbewegung durch den Verhältnissen der Münzwerte entsprechende Übersetzungsverhältnisse in den Getriebezügen auf das Zählrad 38 so zu übertragen, daß dieses sich bei höherwertigen Münzen um einen entsprechend größeren Winkel dreht.It is not necessary for the escapement wheel 24 to have a different number of teeth than the other escapement wheels 16 and 31. It is simply a matter of a reciprocating movement of one of the escapement armatures 9, 10, 11, the rotational movement thus released by the ratios of the To transfer coin values corresponding transmission ratios in the gear trains to the counting wheel 38 so that this rotates through a correspondingly larger angle in the case of higher-value coins.

Es ist auch möglich anstelle der im Ausführungsbeispiel beschriebenen, je einem Getriebezug zugeordneten Energiespeicher nur einen Energiespeicher vorzusehen, der allen Getriebezügen zugeordnet ist.It is also possible to provide only one energy store, which is assigned to all the gear trains, instead of the energy stores described in the exemplary embodiment and each associated with a gear train.

Soll nur ein Energiespeicher eingesetzt werden, dann lässt sich dieser beispiels weise so anordnen, daß er direkt auf das Zählrad oder die Summenwelle wirkt. Bei jedem Freigeben einer der Hemmanker dreht sich dann das Zählrad um einen entsprechenden Drehwinkel.If only one energy storage device is to be used, then it can be arranged, for example, so that it acts directly on the counter wheel or the sum wave. Each time one of the escapement arms is released, the counter wheel rotates by a corresponding angle of rotation.

Der Energiespeicher wird dann bei ausgekuppelter Summenwelle 39 aufgezogen. Die Nullstellung der Anzeigewalze 43 wird so gelegt, daß sie bei aufgezogenem Energiespeicher eingestellt ist. Die Herzkurve 40 kann dann entfallen. Das Zurückstellen der Anzeigewalze und der Nockenscheiben erfolgt in diesem Falle zugleich mit dem Aufziehen des Energiespeichers.The energy store is then pulled up when the sum shaft 39 is disengaged. The zero position of the display roller 43 is set so that it is set when the energy store is drawn up. The heart curve 40 can then be omitted. In this case, the display roller and the cam disks are reset at the same time as the energy store is being opened.

Wenn mehr als drei Münzwerte zu verarbeiten sind, werden entsprechend mehr Getriebezüge eingesetzt.If more than three coin values are to be processed, more gear trains are used accordingly.

Mit dem beschriebenen Münzzählwerk lassen sich auch mehrstellige Verkaufspreise, beispielsweise 1, 20, DM, einstellen. Die Zehnpfennigmünze wäre in diesem Fall der kleinste Münzwert, der einen Schritt des Zählrads bewirkt. Falls bei solchen Verkaufspreisen der konstruktiv notwendige Durchmesser der Anzeigewalze und der Nockenscheiben zu groß wird, kann für jede Stelle eine eigene Anzeigewalze und Nockenscheibe vorgesehen sein, wobei diese dann mit den bei Zählern üblichen, beim Zehnerübergang schaltenden Fortschalträdern verbunden sind.With the coin counter described, multi-digit sales prices, for example 1, 20, DM, can also be set. In this case, the ten pfennig coin would be the smallest coin value that causes one step of the counter wheel. If the constructionally required diameter of the indicator roller and the cam disks becomes too large at such sales prices, a separate indicator roller and cam disc can be provided for each location, which are then connected to the indexing wheels that are common with counters and switch at the tens transition.
