Description

[Detailed description of the invention] This invention electrically determines the quality and type of coins that are inserted, and sorts coins that are determined to be good according to their type, and immediately removes coins that are determined to be defective. This invention relates to a coin processing device for returning coins.

Various types of such coin processing devices have been proposed in the past.In the past, coins were sorted purely mechanically, but in recent years, coins have been electrically judged to be good or bad and to judge the type. Additionally, devices that operate a sorting mechanism for sorting coins are generally used.

However, with conventional coin processing devices, there is a limit to the number of coins that can be accumulated due to sorting and accumulation, so a mechanical outlet for excess accumulation is installed, and more than a predetermined number of input coins are sent to the coin return slot. Automatic return has the disadvantage of complicating the structure and increasing the size of the device, and if this disadvantage is made possible to use a plurality of coins, 1. It was especially noticeable.

The present invention was devised to eliminate such drawbacks of the conventional technology, and has a simple structure that enables reliable detection of excessive accumulation due to coins inserted just before, and eliminates the old method of sorting coins. In order to achieve this purpose, the coin sorting mechanism is actuated by a timer time-up output that is activated when a coin is judged electrically, and the coin sorting mechanism is operated by a timer time-up output that is activated when a coin is judged electrically. Accordingly, excessive accumulation of coins is detected by a coin detector provided near the entrance of the J coin storage section, and when this detection output is generated, the operation of the coin sorting mechanism is inhibited.

The details of the present invention will be explained below with reference to figures showing implementation ψ11.

FIG. 1 is a conceptual diagram showing the configuration of a coin storage section for a pay-type public phone selected as the implementation PI and directed to the opposite phone. , indicates a case where high-value coins can be used, and coin slot 1
The coins inserted into the coin are passed through a first slope forming a coin trajectory, in which a material discriminator C01 used as an electric discriminator and coin detectors DA1DA2 for detecting the outer diameter of the coin are arranged on both sides. 2, and enters a similar second slope 3, which is operated by 1 in accordance with the quality of the coin and the outer diameter determined by the output of the material discriminator CO and the coin detectors DA and DA2. As the storage levers 4 to 6 as a mechanism move backward to the side of the second slope 3, low denomination coins are transferred to the low denomination pocket γ serving as a coin storage section, and upper class coins are transferred to the similar upper class pocket 8. High-value coins are similarly dropped into the high-value pocket 9, pressed against storage levers 10 to 12, and stacked one by one, and accumulated for each type of coin.

However, since the accumulation levers 4 to 6 do not operate, defective coins or counterfeit coins roll on the accumulation levers 4 to 6 and are returned to the coin return port 13.

In addition, the return lever 14 can be turned on by on-hook when a call ends.
is activated, and all remaining coins accumulated on storage levers 10 to 12 are returned.

The material discriminator CO uses a coil connected to an oscillation circuit, and the output of the oscillation circuit changes as the coil is affected by the magnetic permeability depending on the material of the coin. The material of the coin is determined by

In addition, the coin detectors DA 1 and DA 2 are provided with a light emitting element such as a light emitting diode and a light receiving element such as a phototransistor facing each other, and whether or not light is received by the light receiving element depending on the presence or absence of a coin. The coin is detected by this method, and the outer diameter of the coin is determined by calculations to be described later, and the type of coin is determined.

In addition, in Fig. 1, there is a coin detector DA1DA.
Coin detectors CR1 to CR3, CC1°CC3 similar to 2
, CK1 to CK3 are provided, and coin detectors CR1 to CR3 are provided near the entrance of each pocket γ to 90.
The number of accumulated coins is detected, and when the accumulated coins gradually increase and reach the coin detectors CR1 to CR3, this is detected as excessive accumulation and the button is pressed. CC3 detects a waiting coin just before storage, coin detectors CKI to CK3 detect coins to be stored, and coin detector MR detects coins to be returned. 1
When only one waiting coin is stored by the movement of the coin detector 2 moving back to the side, the detection output of the coin detectors CC1tCC3 disappears and the detection outputs of the coin detectors CK1 to CK3 are generated, thereby ensuring that the coin is stored. We have confirmed that it has been stored in safe 15.

Furthermore, the detection output of the coin detector MR that detects the coins to be returned confirms that the coins determined to be defective have been returned.

FIG. 2 shows the detection signal Scm from the material discriminator CO mentioned above.

Regarding the details of the material discriminator CO,% and the material discriminator MJT, an example thereof is provided in the separate application filed by the present applicant.
Details are disclosed in ``Coin Discrimination Apparatus'' (Japanese Patent Application No. 126843/1983).

In addition, the control device CTE includes various gate circuits, counters,

Comparison unit CPR, i, etc., which uses a comparator, etc., compares the material discrimination output from MJM with the contents of material constant memo IJMCM and determines whether the coin is good or bad. Timers TC1 to TC3 and TSM for timing regulation are provided and operate in accordance with the flowchart described later.

Therefore, timers TMJ, TM2, and calculation section ALLJ are as follows.
The outer diameter of the coin is detected using the following principle.

That is, when the Tomori coin C shown by the dotted line in FIG. 1 passes through the coin detectors DA1 and DA2, the waveform of the main part in FIG. 2 and the time chart of FIG. Toosu, detection signal 5 from coin detector DA1DA2

The control unit CNT in FIG. 2 also includes the storage lever 4 in FIG.
A storage magnet SM −, which is omitted in the figure, drives ~6.
8M, the excitation signal 55M13 ~ 55M3 is sent out, and the signal 558M
1 to Ss*3 are caused by the relationship shown in FIG.

That is, when the coin C reaches the device shown in FIG. 1 on the first ramp 2 in FIG.
At the same time as the timer TM1 starts measuring the gap t1, the leading edge of the detection signal 5DA1 also activates the material discrimination section MT, and produces a discrimination output S.sub.1.

Further, the timer TM is also activated by the detection signal S 2 and starts the measurement operation at time t2.

When the rear end of coin C passes just before coin detector DA,
Since the detection signal S disappears, the output of inverter IV is generated.1. This is the stop input S of the timer TM
The timer TM completes the measurement operation at time t1 and sends an output corresponding to time t0 to the calculation unit ALU.

On the other hand, when the front end of the coin C reaches just before the coin detector DA, a detection signal 5Dk2 is generated, which causes the timer T
M2 completes the measurement operation and sends an output according to time t2 to the calculation unit ALU.

Then, the calculation unit ALU performs calculation according to the above-mentioned equation (1) or (2), and calculates the diameter constant A.

A signal corresponding to 0 is generated, which is used as the diameter discrimination result and is sent to the comparison unit CPR.

After the control unit CNT is activated by the measurement end signal, it sends a calculation start signal to the calculation unit AIL/U, and based on this signal, the calculation unit ALU
Arithmetic operations are performed.

Further, the discrimination output SJO of the material discrimination section MT is stored in the material discrimination memory MJM in accordance with the discrimination end signal.

When the calculation unit AL0 generates a calculation start signal, the control unit CNT
reads the read signal to each memory MJM, lV[cM.

DCM, and sends these contents to the comparison unit ℃:PR, corrects the comparison start signal, causes the first comparison unit CPR to start the comparison operation, and by the above comparison operation, determines the material s-i and Based on the outer diameter, judgment is made as to whether it is good or bad and the type.

If the judgment result from the comparison section CPR is good, that is, it corresponds to one of the coin types, then the information is stored via the accumulated profit 1 bus in the processing memo + j c M
``Register to store in M and perform storage processing,
On the other hand, if the coin is defective, that is, the coin does not fall under any of the coin types, the information ``'' is stored in the return processing □ memory CRM via the return control bus, and a registration to perform the return processing is performed.

When the above button is pressed and the coin C is determined and the storage process is registered, the control unit CNT generates a □ timer start signal after the required determination time T has elapsed from the leading edge of the detection signal SDA'2. Start any of the timers TC1 to TC3.

Hl m-, set time 1 of timers TC1 to TC3
The timer TC1 is set according to the time required from when the coin C□ reaches just before the coin detector DA2 until it accumulates and approaches the coin sorting mechanisms 4 to 6.
until the timer TC2 reaches the forward lever 5, the timer TC2
is set to the time required to reach the same lever 6 and is pressed, and when any of these produces a time-up output, this is given as a time-up signal to the control unit CNT, and the rotation unit CNT outputs the coin type determination result. According to signal 88M1~S
S M'a Medium - Sends a message.

Therefore, as shown in Figure 3, timers TC1 to 4'C3
A signal SSMI~55M3 is generated as the time-up of
Detection signals 5CRI to 5CR3 from 1 to CR3 are checked, and it is detected whether or not the coin type corresponding to the coin type to be accumulated from now on in each blur/soto 7 to 9 is in an excessive accumulation state. Assuming that the corresponding one in is not in the detection state, the signal SSMI~55M
Send one of the three.

That is, if the detection signals 5CRI to 5CR3 are in the detection state, the signals SSM□ to 55M3 are not sent out, and the operation of the storage levers 4 to 6 is blocked.

Therefore, when the coin C approaches a predetermined one among the accumulation levers 4 to 6, one of the levers 4 to 6 is activated, and the coin C is reliably transferred to the predetermined one in the pockets 7 to 9. and accumulated.

However, at this time, the transferred coin C is detected by the coin detector CR1.
~CR3, and this detection signal 5
Signal SS when any of CRI to 5CR3 occurs
MI-55M3 is disconnected and the operating storage bars 4-6 are restored.

That is, the storage levers 4 to 6 are operated at a later date after the hard fc is reliably transferred to a predetermined one in the pockets 7 to 9.

Incidentally, when a time-up signal is generated from any of the timers TC1 to TC3, the timer TSM is activated and reset, and when any of the signals 5cR11tR3 is generated, a reset signal is applied and the timer TSM is reset.
If the reset signal is not applied before the set time TSM of the timer TSM elapses and a time-up signal occurs, this causes the control it>CN T to output the signal 55M1.
~55M3 is forcibly disconnected, the operating storage levers 4 to 6 are restored, and subsequent erroneous sorting of coins, etc. is prevented.

This is indicated by the dotted line in FIG. 3.

Also, return processing memo! When the return process is registered to JCRM, based on this, the control unit CNT sends the signal SSMI~5.
The coin C is returned from the coin return port 13 without generating any of the 5M3.

In addition, the storage process registration is erased by the detection signals 5CR1 to 5CR3 from the coin detectors CR1 to cR3, which detect that the coin C has been definitely accumulated, and the return process registration is erased by the coin C from the coin detector MR. It is erased by the detection signal SMH that detects that the coin has been definitely returned, and it enters a waiting state for the next official coin. Prevents the mentioned coin handling.

Although the outline of the operation is as described above, the details are shown in the flowchart of FIG. 4, and the operation of each step is performed as follows.

In other words, in Figure 4, the flit is divided into two sides, a and b, which are connected by the arrows of the phase numbers.

First, referring to figure a, after the entire circuit is started by power-on or off-hook, etc., coin C is inserted and the detection signal 5DAI is generated as a high level (hereinafter referred to as 〆lH"). Material discrimination is performed, and the discrimination output S,.

is stored in the material discrimination memory MJM, and at the same time, at time t1
．． The measurement of time t2 is started, and when the detection signal 5DA2 becomes H'', the measurement of time t2 is completed, and when the detection signal 5DAI returns to a low level (hereinafter referred to as "L"), the measurement of time t1 is also completed, and the coin C The diameter constant ACC of
The contents of the commercials C1 to C3 are compared sequentially.
o:+=c2. The 100 yen coin is collected by @(ACC) 1003, and the coin type is determined based on the outer diameter.

Next, by comparing the discrimination output SJO stored in the material discrimination memo IJ M J M with the contents of the material constant memo 'JMCM, it is checked whether the material is suitable for the determined coin type. , if the contents of the material discrimination memory MCM are set to "O", the material check is omitted and it is finally determined that the coin C should be stored only by determining the coin type based on the outer diameter. , this information determined to be good is registered in the storage processing memo IJCSM.

Then, according to the storage processing registration in the storage processing memo IJC8M, the timer TCI starts when the coin is a 10 yen coin.
As the time increases, it is checked whether there is a return processing registration in the return processing memory CRM, and if there is no error, the signal SSM□ is not //'l (//, that is, the storage lever 4 is recovering. , the detector 5SCRI is checked, and if it is not "H", it is determined that there is no excessive accumulation of coins C, and the signal SSMI is sent out as "H", and the accumulation lever 4 is activated to remove the coins. Accumulate C.

If the coins C are accumulated smoothly, the detection signal 5CRI becomes l/H.
As a result, the □-8 electrical signal SSMI is returned to "L", the storage lever 4 is restored, and the storage processing memo I
The storage processing registration of JC8M is erased, and the series of coin storage operations is completed.

Regarding the above, the accumulation lever 4 is
If the detection signal 5CRI does not become "H" even if activated, the timer TSM activated by the "H" of the signal SSMI
With the time amplifier, the signal SSMI is forcibly set to “L”.
"After closing the storage lever 4 and restoring the storage lever 4, it is determined that an abnormality such as storage failure has occurred, and the storage processing registration in the storage processing memo IJ CSM is deleted, and this information is stored in the return processing memo I.
After registration in JCRM, if the detection signal SMR becomes "H", it is determined that the coin C has been returned, and the return processing memo! JCRM's return processing registration is deleted.

However, as long as the detection signal SMR is "L" and is registered in the return processing memory CRM, the above barking state is maintained, so whether or not the return processing memory CRM is registered after the timer TC1 time up in the coin accumulation process. Click the check button to proceed to the registration deletion of the storage processing memory C8M.
Coin accumulation processing for subsequent coins is stopped.

The same applies when the coin is determined to be a 50 yen coin or a 100 yen coin, but if it is determined to be something other than these, it is registered in the return processing memo IJCRM as a defective material or diameter, and the return processing is performed.

The detection forces of the coin detectors CC1 to CC3 and CK1 to CK3 are used for the puncture control device, and this control device operates the storage levers 10 to 12 and the return lever 1.
4 drives.

In addition, the control device CTE shown in FIG.
