Definitions

  • This invention relates to apparatus for dis ⁇ criminating between acceptable and unacceptable coins. More particularly, the invention is used to test coins fed to vending machines of various types, such as coin- operated laundries, electronic games and dispensing machines for food and the like. The invention repre ⁇ sents an improvement over earlier U.S. Patent Numbers 3,978,962 and 4,089,400.
  • a coin testing apparatus which has a ramp disposed to receive coins supplied to the apparatus and the coins are constrained to roll down the ramp.
  • a first optical means is positioned in predetermined spaced relationship with the ramp to detect the diameter and thickness of a coin rolling therepast.
  • the first optical means includes light emitting means and light sensitive means on opposite sides of the path of the coin, with the light sensitive means mounted in an opening which is positioned such that a coin of proper thickness and diameter will completely cover and block the opening to light passing thereinto from the light emitting means.
  • the light emitting means is disposed in an opening positioned angularly relative to the light sensitive means, so that light can only pass from the light emitting means to the light sensi ⁇ tive means when a coin is of insufficient thickness and diameter to completely block the opening to the light sensitive means.
  • This arrangement enables high intensity lights to be used, thus rendering the apparatus less susceptible to external environmental conditions.
  • a first signal of predetermined timed duration is produced by a first timer circuit.
  • a second optical means is positioned adjacent the first optical means to sense the reflectiveity from the side of the coin and is operable to produce a second signal when the proper reflectiveity is detected.
  • the first signal is supplied to a plurality of latches to reset or enable them, and the second signal is supplied to the latches to set them and provide an output signal which turns on an electromagnet and a solenoid. Coins having magnetic material therein are detained by the electromagnet until the timed duration expires, at which time the magnetic coins are rejected.
  • the solenoid operates a movable ramp segment, urging it from an at-rest position for rejecting coins to an energized position for conveying an acceptable coin past a "vend" device to a collection box.
  • the output signal from one of the latches is supplied to a NAND gate which, in turn, provides a reset signal to a second timer circuit.
  • the second timer circuit is also connected with a third optical means disposed in the path of a coin leaving the ramp. So long as the proper reset signal is supplied to the second timer circuit, the apparatus remains operative and block ⁇ age of the third optical means by a coin moving therepast has no effect. However, if a coin is dropped into the apparatus and an effort is made to draw it back up through the apparatus, blockage of the third optical means will be out of sequence and the second timer circuit will disable or reset the first timer circuit for a predetermine period of time during which a "vend" cannot be obtained.
  • the output or reset signal from the NAND gate is supplied, via a second NAND gate, to another latch to reset the latch.
  • a fourth optical means is positioned to sense a coin progressing through the apparatus from the reject gate or movable ramp segment, and only acceptable coins are detected by the fourth optical means.
  • This fourth optical means is connected to provide a set signal to the last mentioned latch, providing an output to turn on a "vend” mechanism.
  • the time duration set by the first timer circuit is very short, being on the order of about five milli ⁇ seconds. Thus, all of the tests have to be successfully completed within this time in order to obtain a "vend”.
  • the third optical means and second timer circuit effectively prevent "stringing" or withdrawal of coins from the apparatus in an effort to fraudulently obtain a "vend", and a detent or goove is associated with the ramp to receive the string attached to a coin and trap the coin, preventing its withdrawal.
  • FIG. 1 is somewhate schematic perspective view of a portion of the panel of a machine with which the coin testing device is associated, showing the coin testing device in dashed lines;
  • Fig. 2 is a front perspective view of the coin testing device of the invention, showing the front panel thereof in dot-and-dash lines for sake of clarity;
  • Fig. 3 is an end view in elevation of the coin testing device of the invention.
  • Fig. 4 is a greatly enlarged, fragmentary section- al view taken along line 4-4 in figure 2;
  • Fig. 5 is a greatly enlarged, fragmentary section ⁇ al view taken along line 5-5 in figure 2, showing the reject gate in deenergized, at-rest , reject position;
  • Fig. 6 is a view similar to figure 5, showing the reject gate in an energized, accept postion;
  • Fig. 7 is a greatly enlarged, fragmentary section ⁇ al view taken along line 7-7 in figure 6;
  • Fig. 8 is a schematic diagram of a circuit used in the device of the invention.
  • the coin testing apparatus receives and tests a coin C inserted through slot 11 in the front panel 12 of the machine with which the testing apparatus is associated.
  • the coin testing apparatus 10 comprises a body of plate 13 having a rectangularly shaped lower portion 14 and a smaller rectangularly shaped upper portion 15.
  • the upper portion or plate is angularly inclined to the vertica at an angle of about 45 so that a coin fed into the app ⁇ aratus remains in contiguous, sliding contact with the plate 15.
  • a track or rail 16 is supported at the bottom edge of upper plate 15, and as seen best in figure 4, has an inclined upper surface 17.
  • a coin fed through slot 11 drops onto the rail and rolls along the inclined upper surface 17 while resting in sliding contact with the upper plate 15.
  • the rail 16 is inclined to the horizontal whereby the coin rolls downwardly with a suitable speed, and the inclined upper surface 17 of the rail supports a coin in predetermined elevated position, depending upon the thick ⁇ ness of the coin.
  • a first optical device is mounted on the upper plate 15 and comprises an LED 18 supported in a mounting bracket 19 secured to the top of the upper plate 15, and a phototransistor 20 supported on the upper plate 15.
  • the phototransistor 20 is supported in an opening 21 aimed across the path of a coin rolling down the track.
  • the LED is supported in an inclined open- ing 22 aimed downwardly toward the opening 21.
  • a coin C of the proper diameter and thickness will just block the opening 21, preventing light from the LED from striking the phototransistor 20.
  • a second optical device immediately follows the first optical device, and comprises an LED 23 and photo ⁇ transistor 24 mounted in openings 25 and 26, respective ⁇ ly, in the top plate 15 and aimed angularly toward one another.
  • An electromagnet 27 is disposed to one side of the path of the coin rolling down the track 16 and is spaced adjacent the end of the track 16 to detain a coin having magnetic properties and prevent its further advancement through the apparatus.
  • the electromagnet is energized in response to sensing of an acceptable coin by the first and second optical devices.
  • a movable gate or rail 28 is mounted beneath the end of track 16 and magnet 27 and is positioned across the opening into a reject slot or channel defined between a pair of deflectors 29 and 30 on the bottom plate 14.
  • the gate is- moved into position blocking entrance into the reject channel and bridging the space between the deflectors when the first and second optical devices sense an acceptable coin (see figures 2 and 6) . If the coin is unacceptable, the gate reamins in its retracted position as shown in figure 5, and the coin falls into the reject channel.
  • a third optical device comprising an LED 31 and phototransistor 32 is positioned above the gate 28 in the path of a coin rolling along the movable gate.
  • a fourth optical device comprising a LED 33 and phototransistor 34 is positioned in the path of a coin which has traversed the gate. Interruption of this light results in a vend signal.
  • a coin interrupting light to phototransistor 20 causes the phototransistor to go low, and this low signal is applied to pin 2 of 555 timer 35, turning the timer on for a period of time determined by the R-C circuit or timing network 36.
  • the duration of time the 555 timer is on could be on the order of 250 milli ⁇ seconds.
  • the output of 555 timer 35 goes high and is applied to the reset pins of latches L, , L « and L in a 4044 IC, enabling them to be set by the proper signal.
  • the photo ⁇ transistor -24 receives reflected light from LED 23 and provides a high signal to transistor 37, which inverts the signal and supplies a low signal to the latches L,, Lm and L 3 , setting them.
  • Setting of the latches causes their outputs to go high, turning on electromagnet 27 and detaining all coins having magnetic content until the timed duration of the signal from 555 timer 35 expires.
  • the output from latch L 3 is applied to transistor 38, which inverts the signal and turns on or energizes a solenoid 39, extending the gate 28 and bridging the space between deflectors 29 and 30 to support the coin after it leaves the track 16.
  • transistor 38 which inverts the signal and turns on or energizes a solenoid 39, extending the gate 28 and bridging the space between deflectors 29 and 30 to support the coin after it leaves the track 16.
  • the high output from latch L 2 is applied to one input of one quarter of a QUAD NAND 4011 IC, causing its output to go low. This low output is applied to the reset pin of a second 555 timer 41 and to a second quarter 42 of the 4011 IC, causing its output to go high.
  • the high output from the second quarter 42 of 4011 IC is applied to latch L. reset.
  • latch L. reset When an acceptable coin moves past LED 33 and phototransistor 34, blocking light from LED 33 to phototransistor 34, the output from the phototransistor 34 goes low, setting the latch L. and providing an output to a transistor 43 which turns on or energizes vend relay 44.
  • the coin In moving across the gate 28 the coin also passes between LED 31 and phototransistor 32, causing the output of phototransistor 32 to go low.
  • This low signal is applied to the set pin of 555 timer 41, but since the reset pin. is low (signal from NAND gate 40), there is no output from the 555 timer 41 and the output from the third quarter 45 of the 4011 IC stays high. Therefore, the 555 timer 35 continues to provide its output signal for the timed duration originally set.
  • timer 41 is turned on and the output from timer 41 is applied through NAND gate 45 to reset pin of timer 35, resetting it for a predetermined time during which a vend cannot be obtained
  • Another instance which would cause timer 41 to reset timer 35 is when a coin is caused to move back past phototransis ⁇ tor 32, as for example, by means of a string attached to the coin. Because of the timing of the timer 35, this could only occur after the timing sequence of timer 35 had expired. Thus, the low signal from phototransistor 32 would set timer 41 and cause timer 35 to be reset, since there would not be any low signal applied to the reset pin of timer 41.
  • a notch 46 is formed at the lower end of rail 16 (see figures 2 and 7) to trap the string (not shown) whenever someone attempts to obtain a fraudulent vend by the technique of "stringing".

Abstract

L'appareil de contrôle de pièces de monnaie comprend un premier dispositif optique (18, 20) positionné suivant une relation d'espacement prédéterminée par rapport à une rampe (16) le long de laquelle la pièce de monnaie est forcée de rouler après avoir été introduite par une fente d'introduction (11). Le premier dispositif optique détecte un premier paramètre et produit un premier signal d'une durée prédéterminée. Un second dispositif optique (23, 24) est placé adjacent à un côté de la voie ou rampe (16) pour mesurer la réflectivité de la pièce de monnaie et produire un signal de sortie pour une pièce de monnaie ayant les premiers et seconds paramètres appropriés. Le signal de sortie excite un dispositif (27) qui retient les pièces de monnaie ayant un troisième paramètre non approprié jusqu'à la fin de la durée du premier signal. Un mécanisme de rejet (28) est prévu pour rejeter les pièces de monnaie non valides. Un troisième dispositif optique (31, 32) est positionné dans le chemin de roulement des pièces de monnaie quittant la rampe (16) et est connecté avec un dispositif de remise à zéro (32, 35, 41) pour mettre l'appareil hors de fonctionnment pendant une période de temps prédéterminé lorsqu'il y a tentative d'extraire une pièce de monnaie dans le sens inverse au delà du troisième dispositif optique. Un dispositif de détection de pièces de monnaie (33, 34) est positionné dans le chemin de passage d'une pièce de monnaie ayant passé tous les contrôles pour produire un signal de ''vente''.
