Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a denomination indicating device for a coin packaging machine that selectively wraps coins of multiple denominations.

[Technical background of the invention] Generally, a coin wrapping machine inputs the denomination of the coin to be packed, for example, 1 yen to 500 yen, through a denomination instruction input means, and then stores the coins of the input denomination. It is known that the stacked coins are counted in a counting unit, stacked in a stacking unit until a predetermined number of coins, for example 50 coins, are stacked, and then the stacked coins are wrapped. This type of coin wrapping machine has a problem in that if the denomination instruction input means, such as the denomination dial, is switched by mistake during counting or wrapping operations, troubles such as coin jams may occur. In particular, during counting operation, if you switch to a coin denomination with a smaller diameter while there are stacked coins in the stacking section, the mutual spacing will change depending on the diameter of the coins of the specified denomination. Since the members that adjust the coins come close to each other, there is a risk that coins may get jammed in the stacking section or that the peripheral edges of the coins may be scratched. Furthermore, when the denomination is changed, the counted value is automatically cleared, which causes the inconvenience that the counting must be repeated.

[Purpose of the invention] The purpose of the invention is to prevent coin jamming in a coin packaging machine and loss of counting data during counting.

[Embodiments of the invention] The invention will be described below with reference to embodiments shown in the drawings.

Front plates 14 and 14 are respectively attached as holding members for holding.

Near the end of the coin passage 2, a coin detection means 15 using a phototube is provided to detect a passing coin C. When this detection means 15 detects passage of a coin C, a control section 16 (fifth A predetermined pulse is applied to a pulse motor M via a motor (see figure) to rotate the motor M by a predetermined angle.

In the illustrated example, the interval between the left and right belts 6, 6 is set to the optimum state according to the denomination, taking into consideration the case where the coins C to be accumulated are of many denominations and the outer diameter differs depending on the denomination. It is equipped with an adjustment mechanism.

That is, as shown in FIG. 4, the support blocks 3, 3 are supported by arms, and when this group of arms is set to the denomination to be packaged, the support positions of the support blocks 3, 3 are changed accordingly. It is being adjusted.

A connecting plate 1 is provided on each side of the support blocks 3, 3.

At the other end of the support block 3, the base of the second arm 22 is pivotally supported to the body by a shaft 29, and the distal end of the second arm 22 is pivotally supported by a shaft 30.

The third arm 23 that supports one end of the support block 3 on the lower side (right side when viewed from the front) in the figure has a V
The bent portion thereof is pivotally supported on the body by a shaft 31, and the tip of one arm portion 23a is attached to one end of the support block 3 by a shaft 32.

At the other end of the support block 3, the tip of a fourth arm 24 whose base is pivotally supported to the body by a shaft 33 is pivotally supported by a shaft 34.

The other end of the link 28 is a third arm 23
The arm portion 23a is connected to the intermediate portion of the arm portion 23a. As shown in FIG. 5, a denomination knob 71 is coupled to one end of the denomination setting shaft 26. When the denomination knob 71 is turned to set the denomination, the denomination setting shaft 26 and When the cam 27 rotates, thereby causing the arm 21 to rotate within the range between the position shown by the solid line and the position shown by the chain line in FIG. The belts 6, 6 are moved in parallel so that the distance between opposing running surfaces of the belts 6, 6 is adjusted to match the outer diameter of the selected denomination coin.

On the other hand, the base of a fifth arm 35 is loosely fitted onto the shaft 33 of the fourth arm 24, and a roller 36 at the tip of this arm 35 is attached to the inner surface of the other arm portion 23b of the third arm 23 by a spring 37. It is being hit by force. A connecting plate 38 is fixed to the base of the fifth arm 35, and this connecting plate 38 extends to a position facing between the opposing running parts of the belts 6, 6 on the opposite side from the front plates 14, 14. , a back plate 39 is fixed to this portion. This back plate 39 has the role of a holding member that closes the space between the running parts of the belts 6, 6 and holds the periphery of the coin C. The back plate 39 has the role of a holding member that holds the peripheral edge of the coin C. A protrusion 40 having a semicylindrical horizontal cross section is formed on the surface of the back plate 39 facing the belts 6, 6 so as to be able to enter the gap slightly.

In the figure, reference numeral 41 denotes a shutter provided at the lower end of the coin accumulating section A, which is opened when the accumulated coins Ca are delivered onto the guiding rod 42 of the packaging section. A bearing 43 is provided at the end of the coin passage 2, and is used to smoothly introduce the coin C from the coin passage 2 between the opposing running surfaces of the belts 6, 6.

FIG. 6 shows the control system. The denomination instruction input means 70 in the figure includes the denomination knob 71 in FIG.
In addition to the denomination setting shaft 26, it includes a rotary switch 72 to which the denomination setting shaft is connected, and a denomination instruction input signal corresponding to the denomination set by the denomination knob 71 is generated from the rotary switch 72. .

The denomination setting unit 45 receives the denomination instruction input signal, receives the denomination signal, and provides the denomination signal to the control unit 16.
The control unit 16 has a built-in pulse generation circuit,
It receives a coin detection signal from a coin detection means 15 provided in the coin passage 2, and generates a pulse based on the signal. The drive section 46 drives the pulse motor M by the number of steps corresponding to the number of pulses. As a result, the supports 7, 7' are lowered by a distance corresponding to the number of pulses. The counting means 47 counts the detection signal from the coin detecting means 15, and when the counted value reaches a predetermined value (for example, 50), it sends a signal to the control section 16 and resets itself to prepare for the next counting. . When the control section 16 receives the signal from the counting means 47, it interrupts the supply of coins, transfers the stacked coins to the packaging section, and then rotates the pulse motor M. This reverse drive is performed when the support portion reaches the home position (initial position) and the home position detection means 48 (detection board 1
2 and sensor 13) until signals are sent to the control unit 16.

In addition, when the pulse motor M is rotated by a predetermined rotation angle according to the thickness according to the setting of the denomination, the number of pulses for each denomination coin is determined based on the greatest common divisor of the thickness of each denomination coin to be processed. Or, by setting the number of pulses constant for each denomination and sending correction pulses midway depending on the coin of each denomination, the distance between the passage surface of the coin passage 2 and the top surface of the accumulated coins Ca can be adjusted so that the coin C stands tall. It is configured to control the temperature so that it is within an appropriate range.

The control system of FIG. 6 also includes input of a denomination instruction by the denomination instruction input means 70 ( A circuit is provided to allow denominations (changes) and prohibit input of denomination instructions at times other than the above. That is, the output signal of the zero detection means 74 which detects that the count value of the counting means 47 is zero and the output signal of the fixed position detection means 48 are input to the NAND gate 76 of the lock section 75. The output of NAND gate 76 is the clock terminal of D-type flip-flop 77.
Given to CP. The flip-flop 77 is
Its data input terminal D is connected to the power supply Vcc, and when the input to the clock terminal CP rises, that is, when the count value of the counting means is no longer zero, or when the supporting parts 7, 7' are no longer in their fixed positions. At times, it enters a set state and the output is at a low level. Therefore, the locking solenoid 80 is deenergized, and the locking piece 81 connected to the plunger is projected by a spring (not shown) as shown in FIG. This locking piece 81 is pivotally supported by a pin 82 and comes into contact with a pin 85 provided at the free end of an arm 84 biased by a spring 83, thereby restricting rotation of the arm 84 in the direction of the arrow. A protrusion 86 is formed on the arm 84, and this protrusion 86 acts as a stopper for preventing rotation of the ratchet wheel 87. The ratchet 87 is connected to a gear 89 by a shaft 88, and the gear 89 is connected to the denomination setting shaft 2.
It meshes with gear 90 on top of 6. Therefore, if the locking piece 81 protrudes, the denomination knob 71 cannot be turned even if the user tries to turn it. That is, input of denomination instructions is prohibited.

Returning to FIG. 6, when the output of the NAND gate 76 is at a low level, that is, when the count value of the counting means 47 is zero and the supports 7, 7' are in the normal position, the flip-flop is output via the AND gate 79. It is applied to the clear terminal CL (an inverting element is added to the input side), and the flip-flop 77 is reset. That is, the output becomes high level, energizes the solenoid 80, moves the locking piece 81 backward, and releases the restriction on the rotation of the arm 84. As a result, it becomes possible to input a denomination instruction using the denomination knob 71.

Further, when a clear switch (not shown) is operated, a clear signal is generated, inverted by NOT circuit 78, and applied to the clear terminal of flip-flop 77 via AND gate 79. Therefore, the flip-flop 77 is reset and it becomes possible to input a denomination instruction.

Next, the operation of the above coin wrapping machine will be explained in more detail.

First, when the denomination knob 71 is operated to set the denomination to be processed, the first arm 21 is rotated by the cam 27 via the cam follower 25 as described above.

When the coin diameter of the selected denomination is small, each arm 21, 22, 23, 24 is moved to the side shown by the solid line in FIG. 4, and when the coin diameter is large, it is moved to the side shown by the chain line. 3 moves toward and away from the left and right, and the distance between the opposing running surfaces of the belts 6, 6 is adjusted to match the coin C. At the same time, the fifth arm 35 is also moved by the third arm 23, and its back plate 39 is positioned on the side between the running surfaces of the belts 6, 6, so as to be able to guide the side surface of the accumulated coins Ca.

On the other hand, the coin support parts 7, 7 of the left and right belts 6, 6
is placed near the end of the coin passage 2, and when the coin C supplied from the coin supply section is conveyed on the coin passage 2 by the conveyor belt 1, it is transported from the end of the coin passage 2 by the bearing 43. It is smoothly guided and enters between the opposing surfaces of the belts 6, 6,
The entry position is determined by the edge 4a, and the coin holder moves over the coin support parts 7, 7.

In the coin passage 2, when the coin detection means 15 detects passage of the coin C, the detection means is sent to the control section 16, the pulse motor M rotates a predetermined number of pulses, and the pulley 5 is activated via the gears 10 and 11. Coin 1 rotates and the opposing running surfaces of belts 6 and 6
It is moved downward by an amount corresponding to the thickness of the sheet.
The coin C thus discharged from the end of the coin passage 2
are accumulated one by one between the opposing surfaces of the belts 6, 6.

When the predetermined number of coins to be accumulated is counted by the counting means 47, the coins are transferred to the coin wrapping section as described later, and then the counting signal is sent to the control section 16, and the pulse motor M starts rotating. Continuing, when the sensor 13 detects the fixed position by the detection board 12, it is stopped.

During this time, the conveyor belt 1 is stopped, and the coins C on the coin passage 2 are also stopped by the stop of the counting mechanism.

As mentioned above, the accumulated coins Ca riding on the coin supporting parts 7, 7 between the opposing running surfaces of the belts 6, 6 move downward due to the movement of the belts 6, 6, and the lower end thereof When the coin supporting portions 7, 7 escape outward along the pulleys 5, 5, the lower end of the accumulated coins Ca is transferred onto the shutter 41.

When the coin support parts 7, 7 escape outward, another coin support part 7', 7' comes to a position where it can receive the coin C, waits for the next accumulation, and starts the counting operation again. Accumulation of coins C sent by the conveyor belt 1 is started.

At this time, the previous accumulated coin Ca already on the shutter 41 is transferred onto the support rod 42 located directly below the shutter 41 when it is opened, and transferred to the packaging section.

In the above example, a configuration is shown in which pulse motors M are mounted on the left and right support blocks 3, 3, respectively, and the pulleys 5, 5 of the left and right belts 6, 6 are driven, respectively. , an interlocking mechanism may be interposed so that one of the pulse motors M follows the pulley 5 of the other belt 6. The coin detection means 15 may be any appropriate means such as a phototube or a proximity switch.Furthermore, a sensor 13 and a detection plate 12 are used to detect the fixed position of the belts 6, 6. The fixed position of 7 may be directly detected by a micro switch, a phototube, or the like.

7 to 9 show another example of a coin packaging machine to which the present invention can be applied, in which the coin accumulation section A is composed of three guide rods 50 ₁ , 50 ₂ , 50 ₃ , and these guide rods 50 1 , 50 2 , 50 3 Coins C are accumulated in an internal space surrounded by rods 50 ₁ , 50 ₂ , 50 ₃ , and the arrangement of these guide rods 50 ₁ , 50 ₂ , 50 ₃ is as follows.
A book is arranged at the lower center of the end of the coin passage 2, and two other books are arranged side by side on the left and right at a distance from the end of the coin passage 2, and the coins C introduced into these guide rods 50 ₂ and 50 ₃ are The cumulative position is then determined.

Inside surrounded by the guide rods 50 ₁ , 50 ₂ , 50 ₃ is a shutter mechanism 5 as shown in FIG.
A support device B consisting of 1 is provided.

This shutter mechanism 51 includes the guide rod 50
₁ , 50 ₂ , 50 ₃ , and is installed on this base. It is supported by wound wire ropes 55, 55 so as to be able to rise and fall freely, and one pulley 5 is driven by a pulse motor M.
By rotating the shutter base 52, the shutter base 52 is sequentially lowered.

In the illustrated example, the shutter mechanism 51 is composed of three shutter pieces 56, 57, 58, and the shutter portions 56a, 57a, 58a at the tips of the respective shutter pieces 56, 57, 58 are connected to the respective guide rods ₅₀₁ , 5.
The base is connected to the shutter base 52 by shafts 59, 60, 61 so as to be able to enter and exit from between _{0 2} and 50 ₃ .
It is pivoted at the top.

Gears 61 and 62 are attached to the bases of the left and right pair of shutter pieces 56 and 57 coaxially with shafts 59 and 60 and mesh with each other. A plunger 63 of the SOL is connected, and links 64 are connected between the arcs 57b and 58b of the other shutter piece 57 and the shutter piece 58, and the solenoid SOL protrudes and connects the respective shutter pieces 56 and 57. , 58 all at once,
When each shutter portion 56a, 57a, 58a is removed from between the guide rods ₅₀₁ , ₅₀₂ , ₅₀₃ and the solenoid SOL is demagnetized, the plunger 63 is retracted and the shutter portions 56a, 57a, 58a are moved as shown in FIG. Guide rods 50 ₁ , 50 ₂ , 50 ₃
It is designed to enter between the two and receive the coin C.

In FIG. 7, S ₁ and S ₂ are micro switches. The upper micro switch S ₁ detects the upper limit position of the shutter base 52, the lower micro switch S ₂ detects the lower limit position, and the lower micro switch S 2 detects the lower limit position of the shutter base 52. The operation of switch _S2 excites the solenoid SOL and sends a reverse rotation signal to the pulse motor M.
Shutter base 52 on top micro switch S ₁
When the solenoid SOL is activated, the reverse rotation of the pulse motor M is stopped and the solenoid SOL is demagnetized.

In this example as well, the control unit 16 receives the denomination setting signal from the denomination setting unit 45 and the coin C counting signal.
The amount of rotation of the pulse motor M is controlled through this, and the distance L between the top surface of the coin passage 2 and the top surface of the accumulated coins Ca is kept within an appropriate range.

The accumulation of coins C is carried out in the same manner as in the examples shown in Figs. 1 to 4, and when a predetermined number of coins have been accumulated, the shutter base 52 contacts the micro switch _S2 to operate it. The solenoid SOL is energized by the signal and the shutter pieces 56, 5 are activated.
7, 58 is opened and the accumulated coins Ca are transferred to the next process.

After the transfer, the pulse motor M is reversed to raise the shutter base 52 back up, and at its upper limit, the micro switch _S1 is operated to close the shutter mechanism 51 in preparation for the next accumulation.

FIG. 10 shows part of a control system equipped with a denomination indicating device according to the present invention, that is, a denomination instruction input means 70' and a denomination setting section 45'.

and an 8-bit priority encoder EC which receives the outputs of the Q output terminals of flip-flops FF7, FF6...FF0 at their 7, 6...0 input terminals and converts them into BCD codes, and the 3-bit code output of the encoder EC. Decoder that receives and decodes
It is equipped with DC. The denomination setting section 45' further includes:
Note circuit NT7 NT of denomination instruction input means 70'
6...OR gate OR1 whose output is the output of NT0
The one-shot multivibrator OS1 receives the output of the flip-flop 77 of the lock unit 75, operates on the condition that the output is at a high level, and enters a quasi-stable state for a certain period of time after the output of the OR gate OR1 rises. An OR gate OR2 receives the output of the multivibrator OS1 and the clear signal, and the output of the OR gate OR2 takes the input, and the output is supplied to the clear terminal CL of the flip-flops FF7, FF6...FF0, which have an inverting element on the input side.

Then, the output of the AND gate (one of AD7, AD6...AD0) corresponding to the pressed denomination button becomes high level, and the corresponding flip-flop (one of FF7, FF6...FF0) is set. Then, the Q output is encoded by the encoder EC to become a denomination signal and given to the control section 16.

The denomination signal is decoded by a decoder DC and given to a display device (not shown), and is also sent to flip-flops (FF7, FF6... FF0) other than those corresponding to the set denomination) to keep these flip-flops in a reset state.

The structure of the stacking section is not limited to the above-mentioned example, and the present invention can be applied to any structure as long as it has a support device that changes the supporting position as coins are stacked.

[Effects of the invention] As described above, according to the invention, denomination instructions are not input while coins are being counted or when coins are left in the stacking section, which prevents loss of counting data. Coin jams can be prevented.

In particular, even if there is a power outage with coins left in the stacked area, the support position of the stacked area support device is detected, so there is no need to enter the wrong denomination instruction after power is restored. However, this can be prevented.
