Description

[Detailed description of the invention] This invention relates to a paper sheet counter.

Conventionally, paper sheet counting machines use a suction head mounted on a rotating cylinder to suction and separate a large number of paper sheets held between a holder and a paper presser shaft one by one and count them. is being done.

However, with this type of paper sheet counting machine,
When taking out a predetermined number of paper sheets, it was necessary to grasp the sorted paper sheets by hand, press a reset button, open the holder, release the grip on the paper sheets, and then take them out. . As a result, the remaining paper sheets become scattered,
In addition, there is a risk that the paper sheets may fall over and get stuck in the gaps in various parts of the counting machine, so each time you open the holder and take out the counted paper sheets, remove the remaining paper sheets by hand. This had the disadvantage that the user had to grasp it with a hand, making the operation complicated and time-consuming.
In addition, if the remaining paper sheets are to be counted again, the remaining paper sheets must be set in the holder again, and therefore, when taking out several sets of paper sheets that have been counted a predetermined number, it is necessary to Since the above-mentioned operations have to be repeated many times, there are various problems such as poor work efficiency.

This invention was made in view of the above circumstances,
The purpose of this is to automatically move a predetermined number of paper sheets before the next counting operation starts, so that the paper sheets can be counted continuously. The objective is to provide a class counting machine.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. FIG. 1 is an exploded perspective view of the main parts of the paper sheet counting machine, showing a state in which paper sheets are being held between the paper sheets at the so-called counting position and counting is about to start. a counting device that sequentially turns over paper sheets (hereinafter referred to as banknotes) A one by one and counts them; a holding device that holds the banknotes A; and a take-out device that pulls out the banknotes A counted by the counting device from the holding device. It is configured with a device. The counting device includes five suction heads 2 on a rotary cylinder 1 rotated by a drive device (not shown).
is attached, and when the rotary cylinder 1 rotates, each of the suction heads 2 revolves while rotating on its own axis to suction and separate banknotes A one by one. Further, the holding device includes a holder 3 on which the banknote A is placed, and a holder 3 in which the banknote A is placed on the holder 3.
and a paper presser rod 4 which is held between. That is, the holder 3 has a shaft 5 rotatably attached to its lower part, and is supported by a holder stopper 7 on a holder arm 6 rotatably attached to the shaft 5. A pin 8 is provided upright on the holder arm 6, and the pin 8 is inserted into a guide groove of the link 9, so that the holder arm 6 and the link 9 are interlocked. The guide groove is a banknote A.
is held between the holder 3 and the paper presser bar 4, and while the banknotes are being counted at the counting position, the holder arm 6 is connected to a common groove 9' in which the pin 8 of the holder arm 6 is displaced according to the amount of uncounted banknotes. A first guide groove 10 that rotates the paper presser bar 4 to the side opposite to the rotary tube 1 (i.e., a position away from the rotary tube 1, the so-called banknote loading position), and a 2nd position to rotate to the release position (to release the grip).
These guide grooves 9', 10, and 11 are in communication with each other. Further, the link 9 is rotatably attached to a pin 13 provided at an eccentric position on the cam plate of the holder motor 12. This cam plate includes the first cam 14 and the second cam 14.
and a cam 15, which rotate together. That is, the pin 13 is attached to the first cam 14, and the holder motor 12 rotates approximately half a rotation in the opposite direction from the counting position (clockwise rotation in the drawing is defined as normal rotation). As a result, the first guide groove 10 of the link 9 engages with the pin 8 of the holder arm 6, and the holder arm 6 (i.e., the holder 3) is moved to the banknote loading position. Further, when the holder motor 12 rotates approximately half a rotation forward from the counting position,
The link 9 operates so that the pin 8 moves relatively in the second guide groove 11 of the link 9, and the paper presser bar 4 is rotated to the release position as will be described in detail later. Next, the micro switch 16 operated by the convex portion of the second cam 15 detects the operating positions of the holder arm 6 and the paper presser bar 4, that is, the counting position, and the micro switch 17 detects the respective banknote loading positions described above. Alternatively, the release position is detected, and as will be described in detail later, the operation of the holder motor 12 is controlled in accordance with the operation of this device.

By the way, the pin 8 of the holder arm 6 located in the common groove 9' at the counting position moves into the second or first guide groove 11, 10 (relatively) as the holder motor 12 rotates forward or backward. A mechanism for selecting whether the holder arm 6 is inoperative or activated by being guided by the user will be explained.

One end of the link 9, which is rotatably attached around the pin 13, is opposite to the grooves 9', 10, and 11 (referred to as the tip of the link 9).
It is called the rear end of. ), a spring 18 is attached via a roller 19. When the holder motor 12 rotates in the normal direction when it is in the counting position (see Figure 3 B),
The pin 13 also moves clockwise in the figure. Since a spring 18 is tensioned at the rear end of the link 9, the pin 13
As the holder arm 6 moves, the tip of the link 9 is urged clockwise around the pin 13.
The pin 8 is guided from the common groove 9' to the second guide groove 11, does not act on the holder arm 6, and rotates the paper presser bar 4 to the release position as will be described in detail later.

Also, when in the counting position, the holder motor 12
When the rotation is reversed, the pin 8 of the holder arm 6 is guided and engaged with the first guide groove 10 by an action opposite to that described above, and the holder arm 6 is rotated counterclockwise about the shaft 5. Move to bill loading position.

Next, a coil spring 20 is attached to the holder arm 6 and acts to rotate the holder arm 6 clockwise about the shaft 5.
Thus, when the holder arm 6 of the holder 3 is in the banknote loading position, when the holder motor 12 rotates approximately half a rotation forward, the link 9 is moved by the pin 13 in the direction of the arrow X in FIG. 6
is rotated clockwise around the shaft 5 by the coil spring 20, thereby rotating the holder 3 toward the rotary cylinder 1. Further, the paper presser bar 4 is erected on a paper presser arm 21 which rotates around the shaft 5, and a roller 23 is rotatably attached to the paper presser bar 4. The paper holding arm 21 is attached to a clamp release arm 24 rotatably attached to the shaft 5. The grip release arm 24 is driven by the holder motor 12 and functions as a grip release means for separating the paper presser bar 4 from the holder 3, and has a spring hook 2 at one end.
4' is provided, and a spring 25 is tensioned between this spring hanging part 24' and the spring hanging part 6' of the holder arm 6, and the action of this spring 25 causes the holder 3 to
(integrated with the holder arm 6) and the paper presser rod 4 (integrated with the nipping release arm 24). Further, a roller 26 is attached to the other end of the clamp release arm 24. Further, the clamp release arm 24 is in contact with a stopper 27, and its movement in the counterclockwise direction is restricted. Further, near the holder motor 12, a substantially dogleg-shaped first rotating member 28 is attached so as to be rotatable about a shaft 29. One end of the first rotating member 28 is in contact with a second rotating member 28' via an adjusting member 28'' such as a screw, and the other end is connected to a pin 13 provided on the cam 14. cam part 13'
It is designed so that it is in contact with the Furthermore, the second
The rotating member 28' is attached to be rotatable about the shaft 29, and is configured such that the roller 26 of the clamp release arm 24 comes into contact with one end of the rotating member 28'. Thus, when the holder 3 holder arm 6 is in the counting position, when the holder motor 12 rotates approximately half a rotation forward, the pin 13 causes the first and second rotating members 28, 28' to rotate counterclockwise. As a result, the clamp release arm 24 rotates clockwise around the shaft 5, and the paper presser arm 21 rotates in the same direction, causing the paper presser bar 4 to separate from the banknote A (to the release position) and release the banknote. A's grip is released.

Next, a takeout device for taking out counted banknotes A will be explained. This take-out device has a drive roller 3
0, the driven roller 31, and the guide member 32 (second
(see Figure A). That is, the drive roller 30 is disposed between the rotary tube 1 and the holder 3, and is connected to a drive motor 34 via a belt 33. Further, the driven roller 31 is connected to a shaft 3 supported by a rotating plate 35.
1' is rotatably attached. This rotating plate 35 is rotatably attached to a shaft 36a on a mounting plate 36 provided on the main body of the paper sheet counter (not shown). Further, a pin 37 is provided on the rotating plate 35.
is erected, and this pin 37 connects to the connecting member 38.
It is inserted into a long hole 39 provided at one end of.
The other end of this connecting member 38 is rotatably attached to a pin 42 provided at an eccentric position on a cam plate 41 attached to a drive motor 40 . Further, a coil spring 4 is connected between the pin 37 and the pin 42.
4 is tensioned, and this coil spring 44 rotates the rotary plate 35 in the counterclockwise direction (see FIG. 4A) and adjusts the clamping force of the banknote A. As a result, the driven roller 31
When the drive motor 40 operates, the pin 42 causes the connecting member 38 to rotate the rotary plate 35 counterclockwise, approach the drive roller 30, and clamp the bill A. By the way, as will be described in detail later, the drive motor 40 is driven in accordance with the operation of the present device, and rotates the cam plate 41 approximately half a turn clockwise, and moves the rotary plate 35 to the clamping position (see FIGS. 5 and 6). The micro switch 43 is turned off by the cam plate 41 to detect the clamping position and stop the drive motor 40, and the rotary plate 35 is returned to the normal position (see Figs. 2 to 4 A). When moving, the cam plate 41 turns approximately half a turn clockwise to turn on the micro switch 43, detect a home position, and stop the drive motor 40. Further, the guide member 32 is disposed between the drive roller 30 and the driven roller 31, and is configured to guide the counted banknotes A.
Between the guide members 32, there is an operating piece 4 of a micro switch 45 that operates when the banknote A passes.
5' is arranged.

Further, 46 in the figure indicates that when the set number (predetermined number) of banknotes A has been counted, the remaining banknotes A are placed in the holder 3.
This batch device 46 is configured such that when a solenoid 47 is operated, a separator arm 48 rotates about a shaft 50 against a spring 49. Also, 5 in the figure
1 is a stopper device for stopping the rotary cylinder 1 at a predetermined position, and this stopper device 5
1 is configured such that when the solenoid 52 is de-energized, the stopper piece 53 rotates around the shaft 55 by the spring 54 and engages with one of the engagement recesses 56 provided in the rotary cylinder 1. being done. In order to engage the stopper piece 53 with one of the engagement recesses 56, the rotary cylinder 1 is driven in reverse (rotation clockwise in the figure) by a drive device (not shown), and at the same time, the rotation cylinder 1 is driven into the engagement recess 56 of the stopper piece 53. In response to a detection signal from a micro switch 61 that detects engagement, reverse rotation of a drive device (not shown) is stopped.

The reference numeral 60 is a known check mode microswitch for resetting the count at the beginning of the first counting.

Next, the operation of the paper sheet counter configured as described above will be explained. First, set the number of banknotes to be counted and the number of times to take them out using the setting dial 57-
Set by operating A and 57-B. After this,
When a large number of banknotes A are placed on the holder 3 in the state shown in FIG. 2A and the start switch 3' is operated, the holder motor 12 starts operating from the state shown in FIG. 2B (micro switch 17 on state). Start. That is, when the holder motor 12 operates, the pin 1 eccentrically provided on the first cam 14
3 rotates clockwise to move the link 9 in the direction of the arrow X in FIG. Then, the holder arm 6 is rotated clockwise about the shaft 5 by the coil spring 20, and the holder 3 is rotated in the same direction (towards the rotating tube 1). At this time, the pin 8 provided on the holder arm 6 moves while being in contact with the first guide groove 10 of the link 9, and then the holder 3 holds the banknote A between the paper presser rod 4 and the first guide groove 10 of the link 9. When it is clamped as shown in FIG. 3A, it is separated from the right side of the first guide groove 10 and moved to the common groove 9' (see FIG. 3B). In this way, the holder motor 12 rotates, and the first cam 14 is rotated as shown in FIG.
When the cam 14 is rotated approximately half a turn, the micro switch 16 is actuated by the cam 14 to detect that the holder 3 (holder arm 6) has moved to the counting position, thereby stopping the holder motor 12. At this time, the banknote A held between the holder 3 and the paper presser bar 4 is brought into contact with the suction head 2 of the rotary tube 1 .

By the way, by operating the start switch 3', a motor (not shown) for operating a vacuum pump (not shown) is driven, and the suction head 2 performs a suction operation. Therefore, banknote A is the suction head 2.
2, the frontmost bill A is attracted to the suction head 2, and when a certain vacuum pressure is reached, a vacuum switch (not shown) is turned on and outputs a signal.

When the signal is input to the stopper device 51 and the nolenoid 52 is operated, the stopper piece 5
3 is separated from the engagement recess 56 of the rotary cylinder 1, and the rotary cylinder 1 becomes free (see FIG. 3B). At the same time, the rotary cylinder 1 is rotated by a drive device (not shown), and the suction heads 2 revolve while rotating on their own axis to suction and separate the banknotes A one by one and count them. In this way, as the banknotes A are turned over one after another, the thickness of the remaining banknotes A becomes thinner.
The holder arm 6 is rotated by the coil spring 20 to keep the bill A in constant contact with the suction head 2. Also,
At this time, the pin 8 provided on the holder arm 6 is
It moves within the common guide groove 9'. Then, when the banknotes A are counted by a set number (predetermined number),
Since this count value is input to the comparator circuit 58-A and compared with the set value, a coincidence signal is input from the comparator circuit 58-A to the batch device 46, which activates the solenoid 47 and resists the spring 49. The separator arm 48 is rotated about the shaft 50 to separate the remaining banknotes A from the banknotes A for which the set number of banknotes have been counted, as shown in FIG. 4A. Almost at the same time, the vacuum switch is turned off, and a stop signal is output to each drive device of the rotary cylinder 1 and the vacuum pump, and an operation signal is also output to the stopper device 51. When the operation signal is input to the stopper device 51 in this way, the excitation of the solenoid 52 is released, and the stopper piece 53 is urged to rotate by the spring 54 as shown in FIG. The rotary cylinder 1 is stopped at a predetermined position by being engaged with the engaging recess 56 . At this time, since the rotary cylinder 1 slightly overruns, the above engagement is caused by the micro switch 61.
A reversal signal is input to the drive device of the rotary cylinder 1 until it is detected.

Further, at the same time that the counting coincidence signal is input to the batch device 46, an operation signal is also input to the drive motor 40 of the take-out device. As a result, the cam plate 4
1 rotates approximately half a turn and connects the connecting member 38 via the pin 42.
is moved in the direction indicated by the center mark Y in FIG. 4A, and the rotating plate 35 is rotated counterclockwise. As a result, the driven roller 31 approaches the driving roller 30 as shown in FIG.
be held in between. In addition, each of the rollers 3 at this time
The clamping force of 0.31 becomes the tension of the coil spring 44. When the banknotes A counted in this manner are held between the rollers 30 and 31, the cam plate 41 turns off the micro switch 43 and the drive motor 40
At the same time, an operation signal (normal rotation signal) is input to the holder motor 12. As a result, the holder motor 12 further rotates, and the first
When the second rotating members 28 and 28' are rotated counterclockwise, the clamp release arm 24 is rotated clockwise against the spring 25, as shown in FIG. 4B. As a result, the paper presser bar 4 is separated from the banknote A, and the banknote A is released. At this time, the pin 1
3, the link 9 also moves, but since the tip of the link 9 is biased clockwise by the action of the spring 18 as described above, the pin 8 provided on the holder arm 6 moves into the second guide groove 11. , the holder arm 6 does not move, and therefore the holder 3 does not move either. As the drive motor 12 rotates in this way, the second cam 15 operates the micro switch 17, thereby detecting the release position and stopping the holder motor 12, and also stopping the drive motor 34 of the extractor.
Input the operation signal to start driving. As a result, the drive roller 30 rotates clockwise in the drawing via the belt 33, and the banknotes (counted banknotes) A held between the rollers 30 and 31 are sent out between the guide members 32 (see FIG. 6). ). When the micro switch 45 is turned on by the actuating piece 45' disposed between the guide members 32 due to the delivered bill A, a reverse rotation signal is outputted from the micro switch 45 to the holder motor 12. As a result, the holder motor 12 is reversed, and the paper presser rod 4 is moved to the banknote A side by the above-mentioned reverse operation, and the holder 3
The banknote A is held between the two. After that, when the counted banknotes A are removed from the guide member 32,
The micro switch 45 is turned off, and signals are output from the micro switch 45 to the batching device 46, the drive motor 34 and the drive motor 40 of the take-out device. As a result, the power supply to the solenoid 47 of the batch device 46 is cut off, and the separator arm 48 is separated from the banknote A by the spring 49, and the second
The drive motor 34 returns to the original state shown in FIG.
is stopped, and the drive motor 40 further rotates to rotate the rotating plate 35 clockwise via the connecting member 38, causing the driven roller 31 to move from the driving roller 30 to the second
It returns to its original state as shown in Figure A. At this time, the micro switch 43 is turned on by the cam plate 41, and the drive motor 40 is automatically stopped.

In this way, the drive motor 40 is stopped, and as described above, the motor that drives the vacuum pump starts driving, and the vacuum switch is turned on, so that the rotary cylinder 1 is operated again and counting is started. , the banknotes A are counted in the same manner as described above, and the counted banknotes A are sequentially taken out by the takeout device. As a result, the same number of banknotes A (set number)
Continuous classification can be performed automatically for each time.

Further, as shown in FIG. 7, when the micro switch 45 is turned off, the number of times the sheet is sent out is counted (see symbol 62), and the number of times the sheet is taken out is determined by the setting dial 5 as described above.
7-B, the comparison circuit 58-B checks the number of times of extraction, and if they do not match, the counting operation is performed again, and when the set number of times of extraction is completed, the count is automatically terminated.

Furthermore, as shown in Fig. 2A and Fig. 3A, a micro switch 63 and an actuating piece 63' are provided to detect the remaining uncounted sheets on the holder 3. The start signal 65 is output after confirming the on state of the micro switch 63 due to the upper paper sheet. If there is no paper, the microswitch 63 is turned off, and in this case an alarm signal 66 is output.

In addition, to classify an unspecified number of bills (when changing the set number each time), it is sufficient to operate the numeric keypad 59 instead of the setting dial 57. In this case, even if the counted banknotes A are taken out, the numeric keypad 59 The next counting operation will not start unless this operation is performed.

As explained in detail above, according to the present invention, not only can the counted paper sheets be automatically taken out from the holder, but also the paper sheets can be counted while being held between the holder and the paper presser bar. By moving the paper presser bar, the paper sheets that have been stored are sandwiched between a driving roller and a driven roller so that they can be easily removed, and then fed out while being pinched from both sides by a pair of mutually parallel guide members. It is possible to take out subsequent paper sheets in an orderly stacked state, and in addition, it is possible to take out several sets of paper sheets in succession, making it possible to streamline the work of sorting paper sheets. This effect is achieved.
