Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet counting machine, and more specifically, after counting one end of a bundle of paper sheets, the other end is automatically counted again and the counting results at both ends are compared. This invention relates to a paper sheet counting machine that is capable of checking counted values.

Conventionally, when counting paper sheets, especially banknotes and securities, a plurality of suction heads are installed on a rotary plate so as to be able to rotate and revolve, and a supporting plate installed near the rotation trajectory of the heads is used. A sheet of paper to be counted is attached, the upper corner of one end of the outermost sheet of the bundle of attached sheets is sucked by one of the heads, and the paper is picked up by the rotation and revolution of the suction head on the rotary plate. Paper sheet counting machines that count a bundle of leaves while turning them over one by one are being put into practical use in large quantities at banks, securities companies, and other places that handle valuable paper sheets.

However, such a conventional sheet counting machine counts one end of the bundle of sheets, then removes the sheet from the clamping plate, changes the direction of attachment, and then counts the other end again. was manually verified by an operator.

This is time-consuming, and when there are a large number of paper sheets that need to be counted, it fatigues the operator and reduces work efficiency.

Furthermore, when the operator manually reverses the attachment direction, there is sometimes uncertainty as to whether the attachment direction has been reliably reversed, and reliability is also limited.

The purpose of this invention is to eliminate the above-mentioned drawbacks of the conventional technology, and its features are that the clamping mechanism that clamps the bundle of paper sheets can be moved back and forth with respect to the counting section, and that the clamping mechanism that clamps the bundle of paper sheets can be moved back and forth with respect to the counting section. A means for rotating the bundle of paper sheets by 180° is provided,
After counting one end of the bundle of paper sheets, the other end is automatically counted, and means for storing the counted values at both ends and means for comparing the two counted values are provided to obtain the counted results. This paper sheet counting machine provides improved counting efficiency and reliability by comparing and confirming the following.

Hereinafter, an embodiment of the present invention shown in the drawings will be described in detail.

As shown in FIGS. 1 and 3, the paper sheet counting machine of the present invention includes a counting device 1, a paper sheet clamping device 2, a reversing device 3, a vertical movement device 4, a leading edge regulation detection device 5, and a lateral feed device 6. , a suppression device 7, a counting device 8, and a display operation section 9.

As shown in FIGS. 1 to 3, the counting device 1 has the same structure as that of a conventional paper sheet counter of this type, but a similar mechanism can be employed, so a detailed explanation of the mechanism will be omitted.

The paper sheet clamping device 2 includes ramps 2a and 2a' that clamp and move a bundle of paper sheets A, as shown in FIGS. 1 to 3.
and an elastic body 2b that is located between them and acts to open the paper bundle insertion side, a solenoid 2c that serves as a driving source for clamping the paper bundle A against this elastic body, and this solenoid 2c.
When excited, the link 2d connects the solenoid 3c via the pin.
The force of the clamp 2a is transmitted to the clamp la'.
' clamps the bundle of paper sheets A using the shaft 2e as a fulcrum.

A contact plate 2f is fixed to the clamp 2a, and the contacts 2g are arranged around the clamp 2a as an axis of rotation in order to make the bundle of paper sheets A freely rotatable.

The lead wire of the solenoid 2c is connected to the lower part 2h of the contact point 2g.

A brush 2i is brought into contact with the contact point 2g, and this brush 2i is fixed to the face plate 2j.

(This face plate 2j is a part that moves linearly together with the clamp device but does not move rotationally.

) The solenoid 2c is attached to the clamp shaft 2 by the mounting plate 2k.
a''.

Therefore, the solenoid 2c is configured to rotate and move linearly together with the clamp 2a.

Similarly, the reversing device 3 is attached to a motor 3b (table 4d of the vertical movement device 4) as shown in FIGS. 1 to 3.

) is mounted clockwise, a gear 3d and a cam 3f are attached so as to rotate together with the shaft 3c.

Gear 3d is a gear fixed to shaft 2a'' of clamp 2a.
Since it interacts with 3e, it rotates counterclockwise.

A switch 3g is disposed on the outer periphery of the cam 3f, and the cam 3f is provided with a recessed portion at one location so that the switch 3g is turned off in this recessed portion.

Since the ratio of gears 3d and 3e is 1:2, the gear
Even if gear 3d makes one revolution, gear 3e only makes half a revolution.

In addition, 3a in the figure is a bearing of the shaft 2a'' of the clamp 2a.

As shown in FIGS. 1 to 3, the vertical feed device 4 has a motor 4a, which is a part of the device, attached to a table 6a, which is a part of the horizontal feed device 6, and a motor shaft 4.
A gear 40 is attached to b so as to rotate at the same time.

Since this gear 4c and the rack 4d fixed to the table 6a are engaged with each other, when viewed from the axial direction, the gear moves in the Y direction (forward) when rotating counterclockwise, and moves in the Y' direction (reverse) when rotating clockwise.

As shown in FIG. 1, the tip regulation detection device 5 includes a light emitting element 5
a, 5b and light receiving elements 5c, 5d, and whether or not light is received by the light receiving elements 5c, 5d, that is, the two light receiving elements 5
c and 5d are both turned off because the light from the light emitting elements 5a and 5b are blocked by a bundle of paper sheets, only the light receiving element 5c is blocked and turned off, or both of the light receiving elements 5c and 5d are turned on so that they can both receive light. The third embodiment is for regulating and detecting the attachment position of the bundle of paper sheets to the clamps 2a, 2a' in the vertical feeding device 4 described above.

A motor 6b constituting a part of the lateral feed device 6 is fixed to a mounting frame (main body) 6c, and a gear 6e is attached so as to rotate together with a shaft 6d.

This gear 6e and gear 6f are meshed to form a gear 6f.
A shaft 6g is fixed to the shaft 6g, and a male screw 6h is further provided on the shaft 6g, which is screwed into the only screw 6i of the table 6a.
When the motor 6b rotates clockwise when viewed from the axial direction, it moves in the X direction (right direction), and when it rotates counterclockwise, it moves in the X' direction (left direction), but each direction is controlled by the limit switch 6.
j and 6k.

The suppression device 7 is similar in principle to a conventional gripping device, and when the motor 7a rotates, a cam 7b fixed to the shaft 7j of the motor 7a is rotated.
rotates counterclockwise around the shaft 7j, the connecting rod 7c is pushed by the shaft 7d of the cam 7b, and the other end of the connecting rod 7c is pushed against the shaft 7e.
Since it is rotatably connected to the pressing plate 7f, the pressing plate 7f makes opening and closing movements with the shaft 7g as a fulcrum.

The switches 7h and 7i are used to maintain rotation when the cam 7b is on the convex portion.

The counting device 8 is the same in principle as the conventional one, and will therefore be omitted.

Next, the operation of the paper sheet counting machine of the present invention will be explained using FIGS. 1 to 4.

The state shown by the solid line in FIGS. 1 to 3 is the counting operation standby state.

For example, if the clamps 2a and 2a are open, insert the banknote A in line with the tip regulation plate (not shown),
Press check switch 9a, then press start switch 9
If you press c, the check signals that generate the respective signals will be sent to AND gates 18-20. 22, is input to the inverter 21.

The start signal is OR gate 23, flip-flop 2
Input to the S terminal of 4.25 and set each flip-flop amplifier 24.25.

The output of OR gate 23 is counter 26, counter 2
7 and resets the counters 26 and 27, respectively.

When flip-flop 24 is set, its output terminal Q
is connected to the input terminal of AND gate 28, so
The solenoid 2C of the clamp device 2B is actuated by the output signal of the flip-flop (hereinafter simply referred to as FF) 25, which waits for a signal from the AND gate 29.

Due to this operation, the clamp 2a' is closed, so that the banknote A is clamped.

The output signal of the FF 25 is also applied to the AND gate 30. The left limit switch 6J is operating, but the cam switch 3g and the monostable multivibrator 31 are inactive, so the output of the OR gate 132 is L ( low level).

4 Also, since the output of the AND gate 18 and the output of the right limit switch 6k are input to the OR gate 33, the output of the OR gate 133 is at L level, and furthermore, the signal is inverted by the inverter 34 and input to the AND gate 30. And since the FF 35 is set by the output of the left limit switch 6j, the output end is at H level.The switch 71 of the suppressor 7 is turned OFF by the recess of the cam 7b.This state is the state in which the pressing plate It is in an open state and emits an L level signal, which is inverted by an inverter 36 and input to AND gates 30 and 37.

Therefore, the output of the AND gate 30 becomes H level, which becomes the drive signal for the motor 6b of the traversing device 6.

This signal causes the motor 6b to rotate, and the horizontal movement table 6
Move a in the X direction.

When the lateral movement table 6a moves sufficiently and reaches the counting start position, the right limit switch 6k is activated, issues a signal, closes the AND gate 30, gives a rotation stop signal to the motor 6b, and turns off the motor of the pressing device 7. A rotational operation signal is applied to a, thereby closing the suppression plate 7f.

Through the operations so far, the bill A and the press plate 7f reach the position shown by the two-dot chain line, and this is the counting start position.

In FIGS. 1 and 2, when the suction port 1c of the suction shaft 1b arranged on the circumference of the rotary cylinder 1a in the rotational direction is blocked by banknotes as shown in the figure, the vacuum pressure of the vacuum pump (not shown) increases. The pressure gradually reaches the specified value, and the vacuum switch 38 is thereby turned on and generates a signal.

This signal causes the motor 1d of the counting device 1 to rotate, and this rotation is transmitted to the rotating barrel 1a via the belt, so the rotating barrel 1a rotates in the counterclockwise direction shown by the arrow.

When the rotary tube 1a rotates, the suction shafts 1b arranged in the direction of the rotation radius of the rotary tube 1a rotate in the clockwise direction shown by the arrow, and the suction shafts 1b rotate in a orbit restrained by the rotary tube 1a. 1c, each time bills A are picked up and turned over one by one, a detection pulse is emitted by a detector 1e provided facing the rotary cylinder 1a.

When the vacuum switch 38 is on, the AND gate 29 is in the detection pulse waiting state, so the detection pulse passes through the AND gate 29 and further through the AND gate 28 to the input terminal of the counter 26. Since it falls into T,
The counter 26 counts detection pulses that arrive one after another.

When performing a counting check to check whether the number of accumulated banknotes to be counted is a certain number, if the setting switch 9e is set in advance, the setting value of the setting switch 9e and the count value of the counter 26 can be set. are compared by the comparison circuit 39.

When all the bills A have been counted at one end, the suction port 1c is released to atmospheric pressure, so the vacuum switch 38 is turned off and a signal is issued.

This signal causes the rotation of the motor 1d to be stopped, the motor 12a to be rotated, and the suppression plate 7f to be opened.

(The data detector 40 detects that the count value of the counter 26 is not 0 and inputs it to one gate of the AND gate 41, and the falling signal of the vacuum switch 38 is inverted by the inverter 42 and sent to the other gate of the AND gate 41. As a result, the output signal passes through the OR gate 42, operates the motor 7a, and opens the press plate 7f.

) Since the FF 35 is set by the rising signal of the AND gate 41 and the ON operation signal of the right limit switch 6k, when the suppression plate 7f is sufficiently opened, the motor 6 is turned on at the same time.
b rotates in the opposite direction ζ to move the lateral movement table 6a in the X' direction, and when the left limit switch 6j is activated, the FF 35 is reset, so the output Q falls and the motor 6b stops. .

Since the counter 27 has not yet counted, the count value is O.

The output of the counter 27 is detected by the data detector 43 and outputs a signal indicating that it is O.

This signal is inverted by an inverter 44 and then output to the AND gate 2.
2, the check signal is set by the count check switch 9a applied to the left limit switch 6j.
Monostable multi-by-break 3 when activated
1 is triggered and outputs a signal from its output terminal Q. This signal is input to the AND gate 18 via the OR gate 32.

Therefore, the AND gate 18 emits a rising signal. This signal causes the solenoid 45a to operate to suck the bill regulating plate 45.
When the motor 3b rotates, the motor 3b of the reversing device 3 is rotated, and the motor 3b is pulled down through the link to make the banknote A freely rotatable.
d is fixed, and the gear 3e is meshed with the gear 3d, so that the rotation of the motor 3b is transmitted to the gear 3e.

Since this gear 3e is fixed to the clamp 2a,
A shaft below the clamp 2a is rotatably supported by a bearing 3a, and the bearing 3a is fixed to a vertical movement device 4.

Therefore, when the motor 3b rotates, the clamp device 2 rotates.

The rotation of the clamp device 2 is controlled by the cam switch 3 from the cam 3HC.
The rotation is maintained while g is in operation.

When the cam switch 3g eventually reaches the concave portion of the cam 3f, the gear 3d completes one rotation.

Since the ratio of gears 3d and 3e is set to 1=2 as described above, gear 3e rotates by half a rotation.

That is, this operation rotates the banknote A in half, and after one end is counted, the other end is ready for counting.

If the banknote A is turned in half and the end on the counting side does not reach the regulation position, the light from the light emitting element 5a is received by the light receiving element 5c, and after the operation of the reversing device 3 that emits the signal is completed, the banknote is vertically moved by this signal. When the motor 4a of the device 4 is rotated, the shaft 4
A gear 40 is fixed to b, and this gear 40 is engaged with a latch 4d fixed to the vertically moving table 4d. 4a is rotated and moved until the tip of the banknote A blocks the light from the light emitting element 5a, and once the light from the light emitting element 5a is blocked, the motor 4a is stopped.

Next, when the tip of the inverted banknote A is longer than the regulation length and the light from the light emitting element 5b is cut off at the end of the banknote A, the motor 4a is activated in the direction in which the vertically moving table 4d moves (retreats) in the Y direction. When rotated, the banknote A moves, and eventually light from the light emitting element 5b comes to be emitted to the light receiving element 5b.

When the light emitting element 5d emits light, it emits a signal and stops the rotation of the motor 4a.

The output signal of the light receiving element 5c is input to an AND gate 46, and the output signal of the light receiving element 5d is input to an AND gate 47.

Further, after the operation of the inverting device 3 is completed, the output signal of the OR gate 32 is falling.

This signal is inverted by an inverter 48 and applied to AND gates 46 and 47.

The output signal of the light emitting element 5d is inverted by an inverter 49 and input to an AND gate 47.

On the other hand, after the rotation of the clamping device 2 is completed, the AND gate 30
The motor 6b is rotated by the output signal, and the horizontal movement table 6a is moved to the
When the bill A to be moved again in the direction contacts the stopper 7j and the suction surface of the suction shaft 1b, the banknote A is simultaneously moved from the horizontal movement table 4.
The right limit switch 6k is activated by the edge d.

After the first counting is completed, that is, when the signal of the vacuum switch 38 falls, the output signal of the AND gate 41 causes the FF2 to
4 has been reset, its output terminal Q is falling, and Q is rising, so the AND gate 28 is closed and the input of the pulse emitted from the detector 1e to the counter 26 is blocked, and the AND gate 50 is in a state of waiting for the pulse.

Therefore, the second counting is performed by the counter 27, and the counting is performed in the same manner as described above, and when the counting is finished, the counted values of the counter 26 and the counter 27 are compared by the comparing section 51, In addition, the numerical value set by the setting switch 9e and the counter 26
The comparison result between the count value of the counter 26 and the count value of the counter 27 is compared by the comparison section 52, and the count results of the counter 26 and the counter 27 are displayed on the display sections 9f and 9g, respectively. A display is made.

When the setting value of the setting switch 9e matches the numerical value at both ends of the banknote A, a matching signal is emitted from the comparing section 52, and the lamp 9h is turned on to display that the setting check matches.

Next, if the number of banknotes A does not match the set value, but the count values at both ends match, the comparison unit 51 issues a match signal and the lamp 91 indicates that the numbers match. The numerical value and the second count value are set or
If a match is made with any numerical value, each match signal is
It is input to the AND gate 20 via the OR gate 57.

When the second counting is completed, the AND gate 41
In the same manner, the press plate 7f opens and the FF 35 is set again to move the horizontal movement table 4d to the
The motor 6b is rotated in the direction of movement, and when the left limit switch 6j is activated, the motor 6b is stopped.

When the left limit switch 6j is activated, the AND gate 20
The coincidence signal passes through and is input to the OR gate 60.

Since the FF 25 is reset by the output signal of the OR gate 60 and its output Q falls, the suction of the solenoid 3c is released by this signal.

Therefore, the clamps 2a, 2a' are opened and the clamp on the banknote A is also released.

This signal also releases the suction of the solenoid 45a.

Further, when Q of the FF 25 rises, the suction holding of the solenoid 45a is released.

Naturally, this machine can count only one end of the banknote bundle A, like the conventional machine.

For example, when the count check switch 9a does not designate a check, the output of the count check switch 9a falls and is input to the AND gates 18, 19, 20, the inverter 21, and the AND gate 22, respectively.

The signal is inverted by the inverter 21 and applied to the AND gate 61.

Since all of the gates 18 to 20 other than the AND gate 61 are closed, a signal is issued by the start switch 9c as described above, the first count is counted by the counter 26, and the counted value is transferred to the setting switch. 9e
After the counting is completed, in which the comparison unit 39 compares the set value of
As described above, d moves in the X' direction and stops when the left limit switch 6j is activated.

When the comparison result of the comparator 39 shows a match, the match signal is input to the AND gate 61.

Therefore, when the left limit switch 6j is activated, the coincidence signal passes through the AND gate 61, passes through the OR gate 60, and is input to the reset terminal R of the FF 25.
25 is reset, the FFQ terminal falls, so the suction operation of the solenoid 2c ends, and the clamp 2
a, 2a' are opened, the movement of the lateral movement table 4d is completed only once, and the reversing device 3 does not operate.

Next, if the counting results in the three modes do not match, the banknote A is at the counting start position and the clamp 2
a, 2a', and this state is maintained until a reset signal is issued by the reset switch 9b.

As described above, the present invention automatically reverses the edges of banknotes,
It is possible to provide a high-performance banknote counting machine that can perform counting and fulfill the user's request as a multipurpose banknote counting machine, thereby saving labor costs and improving work efficiency.
