AUTOMATIC COIN DISPOSING SYSTEM
Abstract
The system comprises a discriminator, operable to check coins as
to their relative dimensions or diameters, and to reject coins not
having the proper relative dimensions or diameters, a
discrimination path extending from the discriminator, and a true
coin receiver at the end of the path. A true or false discriminator
checks coins, passing along the path, as to whether they are
genuine or counterfeit, and rejects and discharges counterfeit
coins. This is followed by a damaged coin detector which detects
damaged coins and discharges the same, after which the coins pass
to a genuine coin discharge coupled to a genuine coin replenisher.
The replenisher operates to supply, to the true or genuine coin
receiver, a number of coins equal to the number of coins rejected
and discharged by the true or false detector and the damaged coin
detector. Interrelated control circuits, signal lamps and counters
are provided. The dispensing operation is terminated when a
predetermined number of coins have been dispensed, the termination
of the dispensing operation requiring agreement between two
successive detectors positioned along a discrimination path
immediately in advance of the genuine coin receiver.

Description
BACKGROUND OF THE INVENTION
Heretofore, coin dispensing operations, involving checking the
coins as to size, as to whether they are genuine or counterfeit and
as to the degree of damage, have had to rely upon visual inspection
of the coins by operators. Thus, the operations have been subject
to individual differences in the precision and efficiency of the
operators, due to differences in the manual dexterity and degree of
fatigue of individual operators, as well as to various other
factors.
SUMMARY OF THE INVENTION
The present invention is directed to this aspect of a coin
dispensing operation, and provides an automatic coin dispensing
system including a coin diameter discriminating or checking means
coupled to a discrimination or checking path to guide coins,
passing successfully through the diameter checking means, and also
coupled to a reject coin discharging mechanism. A false or
counterfeit coin discriminating or checking means is provided on
the discrimination or checking path, and discriminates coins on the
basis of whether they are genuine or counterfeit in accordance with
their physical properties, this counterfeit coin checking means
being connected to a counterfeit coin discharging means. A damage
degree discriminating means is also provided on the discrimination
path to detect the degree of damage to coins, and is connected to a
damaged coin discharging means, a. Next there is a means to count
and discharge the coins passed successfully through the coin
diameter discriminating means, the true-or-false discrimination
means and the damage degree discriminating means, and connected to
a genuine coin replenishing means to supply genuine coins to the
discrimination passage in co-operation with said counting and
discharging means. A control means for controlling the number of
genuine coins to be supplied in accordance with the number of
discharged counterfeit and damaged coins is also included.
According to the invention, the coins passed successfully through
the coin diameter discriminating means are led through the
discrimination path for discrimination according to whether they
are genuine or counterfeit coins on the basis of their particular
physical properties, and for checking their degree of damage. The
counterfeit coins and damaged coins are discharged through their
respective discharge means, and only the accepted coins are counted
by a counter means. Meanwhile, genuine coins are supplied from the
genuine coin replenishing means to the discrimination passage in
correspondence to the number of rejected coins already discharged.
The counter then indicates the sum of the accepted and replenished
coins.
According to the invention, since a series of coin dispensing
operations, such as sorting of coins, genuine or counterfeit
discrimination thereof, detection of damage to the coins and the
counting of acceptable coins can be accomplished entirely
automatically, it is possible to greatly reduce the man-hours
required for the dispensing operation and to eliminate
inconveniences such as lowered precision and efficiency of the
dispensing operation that would otherwise have resulted from the
differences in the dexterity and degree of fatigue of individual
operators.
For an understanding of the principles of the invention, reference
will be made to the following description of typical embodiments
thereof as illustrated in the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
In the Drawings:
FIG. 1 is a block diagram illustrating one embodiment of the
invention;
FIG. 2 is a combined block diagram and schematic wiring diagram
corresponding to the system of FIG. 1; and
FIG. 3 is a block diagram illustrating another embodiment of the
invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the Figures, reference numeral 1 designates a coin
diameter discriminating or checking means having a rotary disc
means 1a, a coin diameter discriminating path 1b and a warped coin
discharge mechanism 1c. Although not shown in the Figures, the coin
diameter discriminating path is trifurcated into branch paths, one
being a regular diameter coin discharge checking path connected to
a discrimination path C1 and the other two being non-regular (both
larger and smaller) diameter coin discharge paths connected to a
non-regular diameter coin discharge path C5.
The warped coin discharge mechanism 1c is connected to a warped
coin discharge path C6.
Also, the coin diameter discriminating means 1 is provided with
accessory mechanisms (not shown) such as a coin hopper and a coin
feed means to feed coins to the rotary disc 1a.
Numeral 2 designates a genuine or counterfeit discrimination means
2 consisting of various detecting parts mounted on the
discrimination path C1, through which those coins having
successfully passed through the coin diameter discriminating means
1 are led, so as not to interrupt the flow of coins. It
discriminates whether these coins are genuine or counterfeit coins
from their detected physical properties. For example, it may be one
of the usual mechanisms that are used in the coin discriminating
mechanism of automatic selling machines. It is presumed that there
may be various physical properties of coins that are to be detected
depending upon the shape and material of the coins, and a single
detecting means or a combination of a plurality of detecting means
may be employed to meet the required degree of precision of the
genuine or counterfeit discrimination.
Numeral 6 designates a false or counterfeit coin discharge means
coupled to the counterfeit discrimination means 2. It is actuated
by a counterfeit coin discharge signal fS1 delivered from the
discrimination means 2 so as to discharge the corresponding
counterfeit coin coming along the discrimination path C1 at a coin
discharge branching point B1 to a coin discharge source C3.
Numeral 3 designates a damaged coin discriminating means which
consists of a photo-electric damage detector, mounted on the
discrimination path C1 so as not to interfare with the flow of
coins, and an associated electronic circuit.
Numeral 7 designates a damaged coin discharge means coupled to the
damaged coin discriminating means 3. It is actuated by a damaged
coin discharge signal daS1 delivered from the damaged coin
discriminating means 3 so as to discharge the corresponding damaged
coin, coming along the discrimination path C1, at a damaged coin
discharge branching point B2 leading to a damaged coin discharge
path C4.
Numeral 4 designates a true or genuine coin discharge means
provided at the end of discrimination path C1. Leading from the
coin discharge means 4 is a genuine coin discharge path C2, on
which two detectors P7 and P8 are provided to effect a two-fold
check of the number of discharged coins. As will be described
hereinafter, every time a predetermined number of coins that have
successfully passed through all the discriminating stations are
discharged, the system is automatically stopped and a corresponding
lamp is turned on.
Numeral 5 designates a genuine coin replenishing means which is
coupled through a replenishment genuine coin discharge path C7 to
the genuine coin discharge means 4. A replenishing coin detector P6
is provided on the discharge path C7.
A true coin detector P1 provided on the discrimination path C1
counts the true coins, inclusive of damaged coins, running through
the discrimination path C1. A coincidence signal produced with a
count signal from the detector P1 and a corresponding count signal
from the replenishing coin detector P6 is fed as one count to a
total coin counter A, shown in FIG. 2, to cause advancement thereof
by one step. In this manner, the number of total coins is
indicated.
A counterfeit coin detector P4 provided on the counterfeit coin
discharge path C3, counts the number of counterfeit coins rejected
by the genuine or counterfeit discriminating means 2 and discharged
through the discharge path C3. A coincidence signal, produced with
a counterfeit coin count signal fS2 from the detector P4 and a
corresponding counterfeit coin discharge signal fS2 from the
discriminating means 2, is fed as one count to a rejection coin
counter B for the indication of the number of rejected coins.
A non-regular diameter coin detector P2 provided on the non-regular
diameter discharge path C5 detects coins which have diameters
larger or smaller than the regular diamater. The count signal dS is
also fed to the rejection coil counter B.
A damaged coin detector P5 detects damaged coins rejected by the
damaged coin discriminating means 3 and discharged through the
damaged coin discharge path C4. A coincidence signal produced with
a count signal daS2 from the detector P5 and a corresponding
damaged coin discharge signal daS1 from the damaged coin
discriminating means 3 is fed as one count to a damaged coin
counter D for the indication of the number of discharged damaged
coins.
Because the damaged coins are genuine coins, there are cases where
the number of the damaged coin discharge signals and the number of
actually discharged damaged coins need not coincide. In such cases,
the count input to the damaged coin counter D need not be the
afore-mentioned coincidence signal, but it may be constituted by
the output of the damaged coin detector P5 alone.
When counterfeit coins and damaged coins are discharged, it is
necessary to replenish the genuine coin discharge means 4 with
genuine coins corresponding in number to the number of the
discharged coins. The replenishment may be done automatically every
time a counterfeit or damaged coin is discharged. Alternatively, it
may be done automatically when a predetermined quantity of genuine
coins has passed or has been accumulated. In the instant embodiment
of the invention, the replenishment for the counterfeit coins is
manually accomplished when the genuine or counterfeit
discrimination of a predetermined number of coins is completed,
while the replenishment for the damaged coins is done automatically
and for from the genuine coin replenishing means 5 to the genuine
coin discharge means upon attainment of predetermined numbers of
dispensed coins, which will be described hereinafter in detail. In
the manual replenishment, the count signal RS from a replenishment
coin detector P6 is fed to a manual replenishment counter C for the
indication of the number of manually replenished coins.
The sum of the number indicated by the manual replenishment counter
C and the number indicated by the damaged coin counter D is
indicated by a total replenishment coin counter E.
For the counting of the total number of charged non-dispensed
coins, a detector P3 is provided on the warped coin discharge path
C6. The sum of the number of count signals from this detector P3
and the numbers of signals from the detectors P1, P2 and P4 can be
indicated by a total non-dispensed coin counter (not shown).
Alternatively, a detector PO may be provided on the initial end of
the discrimination path C1, and the sum of the number of count
signals from this detector and the numbers of signals from the
detectors P2 and P3 may be indicated by the afore-said total
non-dispensed coin counter.
Reference character S1 designates a saucer for collecting irregular
or counterfeit coins, reference character S2 a saucer for
collecting damaged coins, and reference character S3 a dispensed
genuine coin container.
Counters F and G co-operate with the respective detectors P7 and P8
for indicating the number of genuine coins discharged into the
container S3. The counter F is of photo-electric type, while the
counter G is of mechanical type.
Characters A', B', C', F' and G' designate counter resetters for
the respective counters A, B, C, F and G. They may be operated to
reset the respective counters after each predetermined disposal
cycle or for repeating the previous cycle.
Counter resetters D' and E' are provided for the respective
counters D and E for independently resetting these counters.
The operation of the above embodiment of the invention will now be
described. A certain quantity of coins of the same kind, for
example 4,000 100-yen coins, that are to be dispensed are charged
into the coin hopper of the coin diameter discriminating means 1.
When the coin dispensing system is started, the coins from the
hopper are automatically supplied through a suitable draw-out means
to the rotary disc means 1a, and thence they are supplied by their
centrifugal force to the coin diameter discriminating path 1b.
The coins that are accepted as having regular diameter are fed to
the discrimination path C1. On the other hand, the coins that have
diameters smaller or larger than the regular diameter are
discharged through the non-regular diameter coin discharge path C5
to the saucer S1. As each rejected coin passes through the coin
discharge path, the non-regular diameter coin detector P2 sends out
a detection signal for counter and indication of the number of
discharged rejected coins by the rejection coin counter B.
Warped coins remaining in the rotary disc means 1a are discharged
through the warped coin discharge path C6 to the saucer S1 by
operating a warped coin discharge switch not shown. When the switch
is turned on, a solenoid is activated to lower the rotary disc.
The regular diameter coins sent forth one by one to the
discrimination path C1 are moved on at a constant speed and at a
constant pitch. In this course, discrimination of genuine or
counterfeit coins and detection of damaged coins are done
momentarily. As the coins successively transferred along the
discrimination path at a constant speed reach the genuine or
counterfeit discrimination means 2, they are momentarily appraised
as to whether they are genuine or counterfeit coins according to
whether they have particular physical properties.
The coins having the afore-said particular physical properties and
discriminated to be genuine coins in the discrimination means 2 are
permitted to proceed straight along the path C1. On the other hand,
if a coin not having the afore-said particular physical properties
passes through the discrimination means and is detected therein as
a counterfeit coin, a false coin discharge signal fS1 is delivered
to the counterfeit coin discharge means 6 to actuate the same, so
that the counterfeit coin is discharged at the counterfeit coin
discharge branching point B1 through the counterfeit coin discharge
course C3.
The false coin discharged through the counterfeit coin discharge
path C3 passes through the counterfeit coin detector P4 and is
collected in the saucer S1.
In order to check whether the number of detections of counterfeit
coins coincides with the number of actually discharged counterfeit
coins, a delayed signal fS1 (D) produced a predetermined time after
each false coin discharge signal fS1 enters delay circuit D1 and a
corresponding counterfeit coin count signal fS2 from the
counterfeit coin detector P4 are coupled to coincidence AND gate
AND1, whose coincidence signal is delivered to the rejected coin
counter B for the indication of the number of rejected coins.
The counterfeit coin count signal fS2 is produced after the
corresponding counterfeit coin discharge signal fS1, so that it
will be readily understood that the delay circuit D1 is necessary
to match the timing of one signal to that of another.
Each of the coins discriminated as genuine coin in the
discrimination means 2 continues to proceed along the
discrimination path C1 and passes through the genuine coin detector
P1. As each coin passes through the detector P1, the latter
delivers a detection signal Ss constituting one count to the total
genuine coin counter a.
The genuine coins having passed through the detector P1 reach the
damaged coin discriminating means 3 for momentary discrimination of
their degree of surface damage.
If a coin whose degree of damage is above a certain datum of
discrimination passes through the discriminating means, a damaged
coin discharge signal daS1 is delivered to the damaged coin
discharge means 7 to actuate the same, so that the damaged coin is
momentarily discharged at the damaged coin discharge branching
point B2 through the damaged coin discharge course C4.
The damaged coin discharged through the damaged coin discharge path
C4 passes through the damaged coin detector P5 and is collected in
the saucer S2.
The damaged coin count signal daS2 from the damaged coin detector
P5 is delivered as one count to the damaged coin counter D. It is
also coupled as a starting signal to the genuine coin replenishing
means 5 to start the same. When the replenishing means 5 is
started, it automatically supplies the a number of genuine coins,
corresponding to the number of its input signals, to the genuine
coin counting and discharging means 4.
The number of replenished coin count signals RS from the
replenishment coin detector P6 and the number of the corresponding
damaged coin count signal daS2 are compared by the comparator COM1.
When both the compared numbers become equal, that is, E = J, a stop
signal is delivered to the true coin replenishing means 5 to stop
the replenishment. The built-in counter J of the comparator is
capable of memorizing the number of count signals from the damaged
coin detector P5.
The replenished coin count signal RS from the replenished coin
detector P6 is also coupled as one count to the total replenishment
coin counter E.
If the relation E = J in the replenishment of genuine coins is
upset and goes to J < E without the replenishing means being
automatically stopped, the genuine coin replenishment
non-coincidence lamp L5 is turned on to indicate the overrun of the
replenishing means 5, whereby the replenishing means is
automatically stopped through an excess replenishment interlock
mechanism with a minimum of excessive replenishment.
The coins successfully passed through the genuine or counterfeit
discrimination and damage degree discrimination and led through the
discrimination path C1 to the genuine coin discharge means 4, and
the true coins supplied from the replenishing means 5 undergo the
final dispensing step of counting and discharging into the
container S3.
The detectors P7 and P8 provided on the discharge path C2 leading
from the genuine coin discharge means 4 deliver respective count
signals fS and gS to the respective counters F and G for the
confirmation of the number of discharged true coins.
The counts of both counters F and G are compared by the comparator
COM2, and every time they simultaneously reach 1,000, 2,000, 3,000
and 4,000 the system is automatically stopped and indicating lamps
L21, L22, L23 and L24, corresponding to the respective counts, are
successively turned on.
After the automatic stoppage of the system the next subcycle
operation thereof can be started by operating the true coin counter
switch PB2.
If the relation F = G is upset, the indicating lamps L21 to L24
will not be turned on.
If no rejected coin is detected, the final indication of both the
counters F and G is 4,000. In this case, the dispensing termination
lamp L1 is turned on to indicate the termination of one cycle of
dispensing.
If rejected coin or coins are detected, the indication of the total
coin counter A is less than 4,000. In this case, the
lack-and-excess lamp L3 is turned on. Then, the operator may
operate the replenishment switch PB1 to operate the replenishing
means 5, thereby supplying the required number of genuine coins to
the genuine coin discharge means 4.
The replenishment coin count signal RS produced from the
replenishment coin detector P6 when each replenishment coin passes
therethrough is coupled to the replenishment coin number counter E
to cause advancement thereof by one step, while it is also coupled
through a coincidence AND gate AND2, which also receives a hold
signal from the reprenishment switch PB1, to the manual
replenishment counter C to cause advancement thereof by one step.
The output signal of the counter C constitutes one input to an OR
gate OR3 whose output signal is fed to the total coin counter A to
cause advancement thereof by one step.
When the indication of the total coin counter A reaches 4,000, the
genuine coin replenishing means 5 is automatically stopped,
whereupon the dispensing operation termination lamp L1 is turned
on.
Also, when the indication of the counters F and G reaches 4,000,
the genuine coin discharge means 4 is automatically stopped.
At this time, the manual replenishment counter C indicates the
number of manually replenished coins, and the total replenishment
coin counter E indicates the number of total replenishment coins (E
= C + D).
If more than 4,000 coins (in excess of possible rejected coins) are
initially charged, the final indication of the total coin counter A
is greater than 4,000. In this case, the lack-and-excess lamp L3 is
also turned on. While at this time all the indicating lamps L21 to
L21 become "on", the dispensing operation termination lamp L1 is
not turned on, indicating that excess genuine coins are present in
the genuine coin discharge means 4. The excess genuine coins
remaining in the genuine coin discharge means 4 may be taken out
and collected in other collecting means than the container S3 by
operating the discharge means 4 through the genuine coin counter
switch.
As has been described in the foregoing, according to the above
embodiment of the invention the coin dispensing operation, unlike
the conventional coin dispensing operation based on the eye of the
operator, requires the operator only to load coins through the coin
inlet and render the system operative, whereby the subsequent
operation is done totally automatically.
Thus, the individual differences in the precision and efficiency of
the conventional manual coin dispensing operation, due to
differences in the individual dexterity, fatugue and various other
factors, can be eliminated. Any one, once taught how to operate the
system, can easily complete a predetermined coin dispensing
operation in conformity to predetermined standards. This permits
not only improving the standards of the entire coin dispensing
operation but also greatly reducing the man-hours required for the
coin dispensing operation, which is an extreme economical
advantage.
Further, the automatic coin dispensing system according to the
invention may be used in combination with automatic peripheral
units such as an automatic non-dispensed coin supplier, automatic
recorder, automatic coin packing machine and so forth. When
combined with these peripheral units, the dispensing capacity may
be further increased and the required man-hours may be further
reduced.
FIG. 3 shows a different embodiment of the invention. In this
embodiment, a total non-dispensed coin number detector PT provided
on coin path CO leading from a coin alignment unit O delivers its
count signal to a total non-dispensed coin counter to indicate the
total number of supplied non-dispensed coins. In the other part of
its construction, as well as in its operation and effects, this
embodiment is entirely the same as the previous embodiment, so
parts corresponding to those in the previous embodiment are
designated by like reference characters in FIG. 3 and are not
described.
While in the preceding embodiments the counterfeit coin discharge
means 6 and damaged coin discharge means 7 are separately provided
and operated by separate signals, they can be combined into a
single discharge means by suitably producing disposal signals.
Also, while in the first embodiment the replenishment of genuine
coins is accomplished in correspondence to the number of
counterfeit and damaged coins discharged in each subcycle, it is
also possible to effect the replenish-ment every time a counterfeit
or damaged coin is discharged.
Further, while in the first embodiment the resetting of the
counters A, B, C and G are effected simultaneously and the counters
D and E are individually reset, all the counters may be
simultaneously reset, if necessary. Of course, it is possible to
arrange that only a particular counter or counters may be reset
independently.
Furthermore, while in the first embodiment a predetermined number
of coins, for instance 4,000, are initially loaded, it is possible
to provide a floating loading system so that the replenishment is
zero.
Still further, the damage degree discrimination may be dispensed
with. For example, if the coin disposing system according to the
invention is to be used for separating new and old 100-yen coins,
both of which are genuine coins, the new coins may be discharged
through the true coin discharge means while counting and
discharging the old coins through the false coin discharge means to
a separate container (or vice versa). In this case, the genuine
coin replenishing means may be adapted to be stopped eather
automatically or manually. Also, the genuine coin replenishing
means may be dispensed with or locked in the inoperative state. In
such a case, the coin disposing system has the single function of
separating new and old coins.
Further, where all the non-dispensed coins are genuine coins, the
genuine or counterfeit discrimination means may be held
inoperative, so as to carry out the damage degree discrimination
alone. In this case, the genuine coin replenishing means may either
be dispensed with or held inoperative.
While some preferred embodiments of the invention have been
described, they are by no means limitative but various changes and
modifications are possible without departing from the scope and
spirit of the invention.
