Definitions

  • the following invention consists of a coin sensor system for vending machines, which is mainly useful for inclusion in automatic machines or apparatus, that are coin operated and whose energy is supplied by batteries, in such a way that by means of the existing sensor system, there is a constant sensor for the detection of the passing of coins and a minimum energy consumption.
  • the coin sensor system is arranged close to the coin slot in the selector, and the same is based on a sensor that detects and measures the vibration produced by the dropping of the coins upon a metal piece, integral to the structure itself of the selector, in such a way that the sensor upon detecting that the coin must be validated, generates a signal in order to apply a supply to the rest of the electronic coin control and measuring system.
  • the sensor system acts in relation to the hardness of the coin, in such a way that if the element inserted into the selector does not have a certain hardness, the vibration produced will be below a reference threshold and the system will remain in standby the inserted element being directly returned, whereby there is a first selection of the elements inserted in accordance with the hardness thereof.
  • the coin sensor system that is presented is especially applicable in automatic machines or apparatus, that are coined operated and whose energy is supplied by batteries.
  • the materialization of the activating mechanism can be carried out in many different forms, and thus in general outline we can consider that mechanism that is defined by an L-shaped strip that rotates with regard to its vertex, in such a way that one of its legs is above the coin slot and its other leg is interposed between a pair of diodes, the rotation thereof being caused by the passing of the coins.
  • the present specification describes a coin sensor system for vending machines, which is especially useful in all those automatic apparatus and machines, that are coin operated, and whose energy is supplied by batteries, the sensor system being basically constituted by a metal body integral to the structure itself of the selector, which is in relation to the coin slot in the selector, and upon which all the coins upon being introduced therein knock, there being means to detect the mechanical vibration of the knocking of the coins against the metal piece, in order to convert this vibration into electric vibration, means to clean the square wave provided for by the comparator, means to activate the switch of energy supply to the electronic coin control and measuring system, and means to deactivate the switch of energy supply to the electronic control and measuring system.
  • the sensor means of the mechanical vibration of the knocking of the coins against the metal piece in order to convert this vibration into electric vibration, are defined by a sensor placed close to said metal piece, considering the electric signal as valid, as long as the signal is above a reference level (Uref) defined by the comparator that the sensor system includes, so that the system is not activated by mechanical vibrations unattributable to the insertion itself of the coins.
  • Uref reference level
  • the means for cleaning the square wave provided for by the comparator are defined by a Schitt device that cleans it on the sides, given that when coins are inserted, the coins bounce against the metal piece itself, in such a way that the bounces produced are thus eliminated.
  • the means to activate the switch that supplies energy to the electronic coin control and measuring system are defined by a bistable device that is activated by the Schitt device switching it at the same time that it activates the switch, feeding the CPU while it operates.
  • the deactivating means of the switch that supplies energy to the electronic control and measuring system are defined by the bistable device that upon being reset by the electronic system itself, once the control and measuring operation has ended, deactivates the switch, the electronic control and measuring system going to the standby state.
  • the selector (1) has a slot for the coins (2) to be validated, all of the coins falling on a metal body (3), close to a piezoelectric sensor (4), for the purpose of converting the mechanical vibration into electric vibration.
  • the sensor system has a comparator (5) for the purpose of establishing a minimum reference level (Uref) necessary to consider as valid the electric signal of the piezoelectric sensor (4).
  • a minimum threshold level necessary to accept the operation of the rest of the electronic coin control and measuring system is established.
  • the sensor system includes connected to the comparator (5) a Schitt device (6) so that in the event that the vibration produced by the knocking of the corresponding coins (2) against the metal body (3), above the reference threshold the square wave provided for by the comparator (5) to the Schitt device, the Schitt device cleans it on the sides and activates the bistable device (7) putting it in the switched stated and activating the switch (8) (on) that supplies the electronic measuring system defined by a CPU (9) with the logic circuit and the analogic circuit.
  • the bistable device (7) stays activated while the validation of the corresponding coins takes place, and once the system has finished operating, the same will retrigger or reset the bistable device (7) deactivating the switch (8) and with this cutting off the supply to the electronic coin control and measuring system.
  • the new sensor system of the presence of coins represents a big advantage, and the same is a result of logical development, given that the owner of the present application, is also owner of Patent of Invention P9602334 which presents a coin discriminating system, which is based on the inclusion of a solid body inlaid integrally in one of the walls of the passage channel of the coins to be validated projecting slightly with regard to the level of the wall towards the passage channel in such a way that all the coins knock against the cited solid body that has a curved surface in order to allow the coins to continue rolling, the mechanical vibration produced during the knocking of the coins being converted into electric vibration by means of a sensor or transducer in order to validate the coins.
