Definitions

  • the invention relates to a method for operating a coin validator with a coin return mechanism in coin validators according to the preamble of patent claim 1.
  • the so-called career support plate which forms a wall of the coin channel through which run the coins to be tested in Münzprüfer along wegschwenkbar designed so that trapped coins or in a Münzstau the coins can be discharged to a return channel.
  • a so-called return lever which is either mechanically by hand or electromechanically actuated. It is desirable to monitor the operation of an automaton when a signal is sent to the coin validator computer as soon as the return is actuated. On the one hand, the coin acceptance is stopped over here until the raceway carrier plate is swung back, on the other hand, the return signal serves as a jamming signal. A frequent occurrence of the return signal is an indication that there is a disturbance. It then needs the remedy.
  • Out DE 197 26 449 has become known a method for testing coins with an inductively operating sensor assembly having a primary and a secondary coil, between which passes through the coin to be tested.
  • the transmission signal is divided into a number of switching steps in periodically recurring sections, and envelopes are formed from the values of the reception signal of the secondary coil at the switching steps repeating the frequency of the transmission signal.
  • An evaluation device forms from the number of concurrently generated envelopes at least one criterion for the purpose of generating the acceptance signal.
  • the known method is based on the recognition that in a field at different frequency different attenuations caused by a coin. Deeper frequencies cause the field to extend completely or substantially through the coin, while higher frequencies result in a so-called skin effect, ie the field only minimally penetrates the coin. With different frequencies, therefore, different properties of the coins can be measured, for example the thickness of the coins with lower frequencies and a stamping image with higher frequencies.
  • the invention has for its object to provide a method for operating a Münzprüers, in which only one probe is sufficient to produce a hinting on the operation of the return mechanism return signal and the return signal is generated relatively quickly and even with small changes in distance.
  • the method according to the invention is based on the knowledge that the maximums of two or more damping curves (envelopes in the above sense) are different, depending on whether the attenuation by a coin or by the fact that the career support was swung away. In the latter case, the attenuation curves (measured value or signal course) are relatively close in their course and would ideally coincide, while different maxima occur when a coin passes through at different frequencies. This phenomenon makes use of the invention. First, it is determined whether the probe at all a measurement signal or two or more measuring signals. This is preferably done in that the exceeding of a predetermined threshold value is determined. Thereafter, two or more attenuation curves are set in relation to each other via maxima. As already mentioned, their relationship is different depending on whether there is a cushioning by a coin or by operating the return lever. A return signal is generated when the difference of the maxima is less than a predetermined value.
  • the principle of measurement which is used in the method to be described, is based on DE 15726449 , known. It is expressly referred to this prior art. It is based on the recognition that at different frequencies of a magnetic field different losses are caused by the passage of a coin through the field. As mentioned above, it does not matter if the field is between a primary or a secondary coil or is generated by a coil assembly located on one side of the coin channel.
  • the causative or transmit signal which is preferably a square or triangular signal, is divided by suitable means into a number of switching steps. Since the causative or transmission signal is a periodic signal, this division takes place again and again.
  • the difference between the maxima makes it possible to easily determine whether the measured damping curves are caused by the actuation of the return lever or by the passage of a coin.

Claims (2)

  1. Procédé de fonctionnement d'un contrôleur de pièces de monnaie, comportant un canal de pièces de monnaie par lequel circulent les pièces de monnaie, un mécanisme de renvoi des pièces de monnaie ouvrant le canal de pièces de monnaie, et une sonde inductive de mesure avec bobine primaire et bobine secondaire, un signal d'émission de la bobine primaire étant, dans des intervalles se reproduisant périodiquement, divisé en un nombre de pas de programme, et, à partir des pas de programme des valeurs associées en temps du signal de réception de la bobine secondaire, des courbes d'amortissement (1 à 9) sont formées, lesquelles courbes d'amortissement (1 à 9) correspondent à un amortissement du signal d'émetteur par une pièce de monnaie traversant la sonde inductive de mesure, pour des fréquences différentes, et, pour reconnaître la pièce de monnaie à partir d'au moins deux des courbes d'amortissement, un critère donnant l'information sur l'admission ou le rejet d'une pièce de monnaie est obtenu,
    caractérisé en ce qu'on détermine d'abord si on dispose d'au moins d'une courbe d'amortissement, et en ce qu'un signal de renvoi attestant de l'actionnement du mécanisme de retour des pièces de monnaie est produit à partir d'au moins deux courbes d'amortissement de la même sonde de mesure, si la différence des maxima des courbes d'amortissement est plus petite qu'une valeur prédéfinie.
  2. Procédé suivant la revendication 1, caractérisé en ce qu'on établit d'abord si au moins une courbe d'amortissement atteint une valeur de palier prédéfinie.
