Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a coin processing machine that can process many types of coins, and in particular, inconveniences when setting the type of coin (hereinafter referred to as denomination) or the number of coins to be counted. It is related to technology for solving the problem.

``Prior Art'' Coin processing machines, such as coin wrapping machines used in banking, are generally known for wrapping 50 coins of each denomination, such as 1 yen to 100 yen.
FIG. 1 shows an example of this type of coin wrapping machine, and in the figure, reference numeral 1 indicates a rotating disk into which coins are inserted. This rotating disk 1 is rotated in the direction of arrow A by a drive motor to apply centrifugal force to the coin. The coins then pass through the slits between the thickness regulating plates 2 one after another and are introduced into the sorting passage 3.

A fixed guide plate 4 on which a sorting shelf 4a with an L-shaped cross section is formed is disposed on the left side of the sorting passage 3, and a movable guide plate 4 on which a sorting shelf 5a with an inverted L-shaped cross section is formed on the right side. A guide plate 5 is arranged movably in the direction of arrow B. A roller 6 and a denomination cam 7 are provided to set the distance between the fixed guide plate 4 and the movable guide plate 5, and the side edges of the coins introduced into the sorting passage 3 are separated by the sorting shelves 4a and 5a. It is supported at a point, and the upper center abuts against the feed belt 8 and is conveyed in the direction of arrow C by frictional force. A denomination dial (not shown) is connected to this denomination cam 7, and by rotating this denomination dial by a predetermined angle, the interval between the sorting shelves 4a, 5a is changed, and the type of coins to be sorted is set. be done.

Further, photo sensors 9a and 9b are disposed in this sorting passage 3 to send out an addition signal UP or a subtraction signal DN according to the direction of conveyance of the coins, and a stop shaft 10 for closing the passage 3 is also disposed. .

The direction in which the counted coins are sent out is changed according to the set operation mode by a chute whose switching operation is performed by a solenoid (not shown). That is,
Either the wrapping mode, in which coins are sent into a coin wrapping machine (not shown), which wraps a predetermined number of coins (usually 50 coins), or the counting mode, in which coins are sent outside the coin wrapping machine and into a coin bag, is selected, and this operation is performed. The sending direction of the chute is changed depending on the mode.

"Problem to be Solved by the Invention" By the way, with this type of coin wrapping machine, if the number of coins is set to 50, the coins are usually wrapped, so the number of coins to be counted is 50. If set to
The counting mode is automatically selected when the set number of sheets is 500, 1000, 4000, 5000, etc.

The subsequent processing of the counted coins differs depending on which mode is set. In other words, in the packaging mode, the counted coins are transferred to the stacking section of the packaging machine (a mechanism that stacks 50 coins).
On the other hand, in the counting mode, the coins are sent to a hopper (to which a coin bag is attached) outside the coin packaging machine for bagging, so the change in the chute is synchronized with the switching of the operation mode. The send direction is automatically set.

However, in the counting mode, the number of sheets to be counted is set to 5,000 sheets, but the number of sheets is reduced to 1,000 sheets during counting.
There may be cases where an operation such as changing the setting is performed, and if such an operation is performed between the number of sheets corresponding to the counting mode (500, 1000, 4000, 5000, etc.), there is no problem, but if you accidentally There is a problem in that the chute is automatically switched during counting to select 50 coins (the number of coins to be set in wrapping mode), and the coins are sent out in two directions and then put away.

In view of the above-mentioned circumstances, it is an object of the present invention to prevent fluctuations in the coin feeding direction due to switching of the chute due to a change in the set number of coins during counting.

"Means for Solving the Problems" In order to achieve the above object, the present invention includes a counting section that counts coins while moving them in a line along a sorting path, and a counting section that counts coins while moving them in a line along a sorting path; a chute provided to switch the direction of coin delivery to the coin packaging machine or to the outside of the coin packaging machine; a driving means for switching the chute; and a zero detection unit for detecting whether or not the counting result of the counting unit is zero. a setting instruction unit that instructs the driving means to switch the chute to the outside of the packaging mechanism or the packaging machine; and a drive instruction from the setting instruction unit on the condition that at least the counting result is zero. A shoot setting control section that allows input to the means is provided.

"Operation" According to the above configuration, during coin counting, some signal representing the number of coins is supplied from the counter to the chute setting control section, so that the counting result is not zero. The instruction from the setting instruction unit is not input to the shoot switching drive unit, and the shoot is not switched.

"Embodiment" Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 2 shows the structure of the counting section of the coin wrap counting machine according to the present invention, and the same parts as shown in FIG. 1 are given the same reference numerals.
The setting motor 26 sets the width of the sorting passage 3 by the denomination cam 7 when rotating in the normal direction, and switches the chute 33 when rotating in the reverse direction. That is, when the setting motor 26 rotates, the gears 26a,
34a and 36a each rotate. In particular, when the setting motor 26 rotates forward, the gear 34a
The rotation of the shaft 35 is caused by the one-way clutch 34b.
Further, the denomination cam 7 is rotationally driven by a transmission mechanism (not shown). Also, the setting motor 26
When the gear 36a rotates in the opposite direction, the rotation of the gear 36a is transmitted to the shaft 37 via the one-way clutch 36b,
Switching lever 41 via lever 38 and link 39
swings around the shaft 40. An arm 42 is fixed to the chute 33 and has a roller 43 at its tip, and this roller 43 is fitted into the long hole 41a at the tip of the switching lever 41. Therefore, in the state shown in FIG.
4 and moves in the direction of arrow D, it is sent out to the outside of the coin wrapping machine by the guide portion 33b.

FIG. 3 is a block diagram showing a counting control circuit for a coin packaging machine according to the present invention. In this figure, first a large number of coins are placed on a rotating disk 1 (see Figure 1).
When the start button is pressed, a start signal ST is applied to the drive section 11.

The drive unit 11 sends an opening signal OP to the rotary solenoid 12 connected to the stop shaft 10, which causes the stop shaft 10 to rotate approximately 90 degrees counterclockwise and open the sorting passage 3. At the same time, the drive unit 11
The feed motor 13 rotates the feed belt 8 and the drive motor 1 rotates the rotary disk 1.
A drive signal DRV is sent to each of the four terminals. As a result,
A large number of coins inserted into the rotating disk 1 pass through the sorting passage 3 one after another and are counted.

The UP-DN discriminator 15 receives passage signals from the photo sensors 9a and 9b sent each time a coin passes.
Based on SA and SB, the counter 16 counts the addition signal UP if the same coin passes in the direction of arrow C, or the subtraction signal DN if the direction is opposite to arrow C.
and sends it to the total counter 17.

The counting counter 16 is made up of, for example, a four-digit IC capable of up-down counting, counts the coins passing through the sorting passage 3, and sends the counting result to the counting data extraction section 18. Counting data retrieval unit 18
The counting results are 50, 500, 1000, 4000 and 5000
At each time, "1" is sent to the sheet number comparison section 19. The sheet number comparison section 19 performs the counting and data extraction section 18 by pressing the setting button of the sheet number setting section 20.
The "1" sent out when 50, 500, 1000, 4000, and 5000 are counted is selected, and the selected "1" is sent to the drive section 11 as the counting end signal CE.
As a result, the drive unit 11 is driven by the rotary solenoid 12.
The blockage signal CL is sent to the feed motor 1.
3 and the drive motor 14 are stopped to stop coin counting.

On the other hand, the total counter 17 is composed of, for example, a 4-digit dynamic scan type IC capable of up-down counting, and when 50 sheets (packaging mode) is set by the sheet number setting section 20,
The counting results of the counting counter 16 are accumulated, and the accumulated results are sent to the sheet number display section 21 and the zero detection section 22. Note that the total counter 17 is cleared by a clear signal CLR1 when the clear button is pressed. Further, the clear signal CLR2 for clearing the count counter 16 is connected to the next count signal and the clear signal CLR1 in the packaging mode, and is connected to the clear signal CLR1 in modes other than packaging.

The zero detection unit 22 detects whether the count result of the total counter 17 is zero or not. It stores zero information for each digit in registers sequentially, takes the AND of the outputs of these registers, and calculates the AND result. In synchronization with the signal that displays the next four digits in the case of zero, the passage setting control unit 23 generates a zero signal ZR (ZR="1");
It is sent to the shoot setting control section 25 and the erroneous operation detection section 28.

This path setting control section 23 includes a drive signal DRV.
The inverted signal of , the zero signal ZR, the mismatch signal NC of the setting comparison section 24, and the non-setting signal ENA of the shoot setting control section 25 are applied, and these are all "1".
In this case, the reverse drive signal RVS is sent to the feed motor 13 and the drive motor 14 for a certain period of time, and then the forward rotation signal FWD is sent to the setting motor 26.

That is, the drive signal is not activated while the coins are being counted.
The DRV inversion signal is “0” and the denomination setting section 2
Press another denomination button of 7 and the discrepancy signal NC is “1”
Even so, the setting motor 26 does not rotate forward.
Furthermore, even if counting is stopped when packaging every 50 sheets, the counting result of the total counter 17 is not zero, so the zero signal ZR is "0", and the setting motor 26 is activated as in the case described above. Normal rotation does not work. Furthermore, since the unidirectional clutches 34b and 36b are used, the non-setting signal ENA becomes "0" while the chute 33 is moving, so as not to simultaneously apply forward and reverse signals to the setting motor 26. The setting motor does not rotate forward. Shoot setting control section 2
5, a packaging mode signal WRM, which is output in conjunction with the setting button "50" of the number setting section 20, and a shoot 3.
Packaging position detection signal WR-P, shoot 3, which is output when 3 sets its guide path to the packaging mechanism side.
The counting position detection signal CO-P, the inverted signal of the drive signal DRV, and the zero signal ZR, which are output when No. 3 sets its guide path on the counting side, are input. If the chute 33 is set to the wrapping position or the counting position in accordance with the output level of the packaging mode signal WRM, the non-setting signal ENA is "1", and if it is not set, it is "0". indicates a mismatch state. When this non-setting signal ENA is "0" (mismatch) and the inverted signal of the drive signal DRV and the zero signal ZR are "1", that is, when all the inputs of the AND gate 31 are "1", the setting motor 26 Outputs the reverse rotation signal BWD to.

That is, the drive signal is not activated while the coins are being counted.
The DRV inversion signal is “0” and the number of sheets setting section 2
Even if the output level of the packaging mode signal WRM is changed by changing the number of sheets of the pattern for changing the mode in 0 (i.e., the non-setting signal
Even if ENA becomes "0"), the setting motor 26 does not operate in reverse. Furthermore, even if the counting is stopped, if the counting result of the total counter 17 is not zero, the zero signal ZR becomes "0" and the setting motor 2
6 does not operate in reverse.

The erroneous operation detection unit 28 detects the mismatch signal NC from the setting comparison unit 24 and the non-setting signal from the shoot setting control unit 25.
ENA, input the zero signal ZR of the zero detector 22,
When the mismatch signal NC becomes "1" (denomination mismatch) when the zero signal ZR is "0" or when the non-setting signal ENA becomes "0" (shute position mismatch), the denomination setting section 27 Or number setting section 2
A blinking signal is generated when it is detected that the switching operation of 0 is an erroneous operation (including operation by quickly pressing the operation button of the number of coins setting section 20 or denomination setting section 27).
The FLC is output, and thereby the display data on the sheet number display section 21 is displayed blinking.

Furthermore, when counting or packaging for one denomination is completed and the clear button is then pressed to set another denomination button in the denomination setting section 27, the discrepancy signal NC becomes "1".
Therefore, the setting motor 26 rotates normally. This normal rotation of the setting motor 26 causes the denomination cam 7 (FIG. 2) to rotate normally via the one-way clutch 34b. On the other hand, three cams are provided in conjunction with this shaft 35, and these three cams control the rotational positions of the denomination cams (these rotational positions correspond to the widths of the six types of sorting passages 3). It is encoded and transmitted to, for example, a microswitch. The code signals SWA, SWB, and SWC from these microswitches are applied to the decoder 30 of the selected section 29, respectively. The decoder 30 decodes the code signals SWA, SWB, and SWC and then sends them to the setting comparison section 24. When the width of the denomination set by the denomination button and the width of the sorting passage 3 set by the denomination cam 7 match, the mismatch signal NC becomes "0" and the setting motor 26 rotates forward. stops and the setting of the denomination is completed.

Furthermore, after pressing the clear button, if the number button of the number setting section 20 is switched in a pattern that changes the mode, the non-setting signal ENA becomes "0".
As a result, the setting motor 26 rotates in the reverse direction. This reversal of the setting motor 26 causes the switching lever 41 to swing via the one-way clutch 36b, thereby moving the position of the chute 33. On the other hand, a packaging position detection switch or a counting position detection switch (not shown) is provided which operates as the chute 33 moves, and outputs a packaging position detection signal WRP and a counting position detection signal COP, respectively. That is, the signal COP
is sent from the counting position detection switch, becomes “1” when the chute is in the counting position, and the signal
WRP is a signal sent from the packaging position detection switch and becomes "1" when the chute is in the packaging position. Then, when the chute is in the counting position, when the 50 sheets (wrapping mode) setting button of the sheet number setting section 20 is pressed, the wrapping signal WRM becomes "1", and as a result, the non-setting signal ENA becomes "0", and the AND GATE In this case, the chute moves from the counting position toward the packaging position, and when the chute reaches the packaging position, the packaging position detection switch is turned on.
The signal WRP becomes "1", and the setting motor 26 stops rotating in reverse. Also, the signal WRP is “1”
Then, the packaging motor 32 is driven.

FIG. 4 is a block diagram showing the parts of the counting control circuit that are changed when electromagnetic clutches 34c and 36c are used instead of the unidirectional clutch, and in this case, the non-setting signal ENA is passed through. There is no need to input it to the setting control section 23.

"Effects of the Invention" As explained above, according to the present invention, it is determined whether or not to switch the chute based on the zero information of the counter that counts coins and the output of the number setting section. Therefore, the motor for driving the chute does not operate during counting, and it is possible to prevent errors in coin feeding caused by changes in the position of the chute. The advantage is that no chute switching is required.
