Abstract

PURPOSE:To correct the wrinkle or curvature of paper sheets and the like by pressing the paper sheets with a pressing means when it is detected that the quantity of the remaining paper sheets becomes small while correcting the wrinkle or curvature by the own weight of paper sheets when the remaining quantity of said paper sheets is large. CONSTITUTION:When a start switch is operated, a take-in roller 50 is rotated to take in paper sheets from a feeding part and a JK-FF circuit 82 is set while resetting an RS-FF circuit 84. At this time, the output signals of AND circuits 86, 89 are at low levels, without driving a motor 56. Accordingly, when the quantity of paper sheets placed on the feeding part is large, a backup 55 is not operated and the paper sheets are taken in only by their own weight. On the other hand, when the quantity of the paper sheets is reduced and a remaining quantity detecting switch 67 is turned on, a high level signal is outputted from the AND circuit 86. Thereby, the motor 56 is outputted from the AND circuit 86. Thereby, the motor 56 is driven and the backup 55 is lowered, to pressingly take in the sheets of paper.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) This invention provides a continuous supply of paper sheets such as banknotes,
The present invention relates to a paper sheet processing device.

(Conventional technology) Conventionally, various paper sheet processing apparatuses of this type have been developed.

For example, (a) Japanese Patent Publication No. 60-55425 discloses a device that uses only the weight of the stacked paper sheets to create a frictional force between the take-in roller and the paper sheets to take in and process the last sheet. is disclosed. Also, mouth) Jitsuko Sho 513501
The publication discloses an apparatus that presses a plurality of paper sheets against a take-in section as a backup, and takes in and processes the paper sheets in this state.

However, both of the above devices have the following problems. In other words, as in (a), when paper sheets are imported without backup, it is possible to add paper sheets, but on the other hand, if the paper sheets are wrinkled or warped, for example, the paper sheets may be When the number of sheets decreases, the adhesion of the sheets to the take-in roller deteriorates, making it easy to take in defects such as skew. However, in the case of (a), since it is just a coefficient, a slight skew does not pose a problem.

In addition, when the paper sheets are pressed with backup as in the case of the opening), it is possible to stably take in the paper sheets until the last one. However, with this configuration, it was difficult to add paper sheets while the paper sheets were being taken in, and it was difficult to process Odai's paper sheets continuously. .

(Problems to be Solved by the Invention) This invention solves the problem of replenishing paper sheets and the problem of supplying pressing force to paper sheets. This makes it possible to add paper sheets without pressing them with a pressing means, and when the remaining amount of paper sheets becomes low, the pressing means presses the sheets to ensure stable intake. The purpose is to provide a paper sheet processing device that is capable of handling paper sheets.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a pressing means for pressing the stacked paper sheets toward the taking-in means, a driving means for driving the pressing means, and a drive means for driving the pressing means in the vicinity of the taking-in means. A remaining amount detecting means is provided for detecting the remaining amount of paper sheets, and according to an output signal of this remaining amount detecting means,
and control means for operating the driving means and moving the pressing means toward the taking-in means.

(Function) In this invention, when there is a certain amount of remaining stacked paper sheets, the paper sheets are not pressed by the pressing means because their own weight corrects the wrinkles and warping of the paper sheets. By doing so, it is possible to replenish paper sheets in this state, and when the remaining amount detecting means detects that the remaining amount of paper sheets is low, the driving means is operated to cause the pressing means to replenish the paper sheets. It is designed to push the class.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

A predetermined number of sheets are accumulated in the accumulation section 24. 25 is a separator device that separates the continuously conveyed banknotes P2 into a predetermined number of bills (for example, 100 bills); such a mechanism is explained in detail in Utility Model Publication No. 53-24776, so it is omitted here. do. 100 banknotes separated and stacked banknote bundle P2
The sheets are wrapped with tape in the sealer 26 and collected in the bundle stacking section 28 in the east conveyance section 27.

In addition, 29 is a tape reel, and the tape feed part 30

As described above, the banknotes P1 supplied from the supply section 3 are conveyed and sorted as indicated by the arrows in FIG.
．． 5.6 or is sorted and accumulated in the direct accumulation section 7,
Further, at the time of sealing, the sheets are sent to the sealing section 2 through the sorting gate 13 as shown by the arrow, sealed in a prescribed number of sheets, and stacked in the bundle accumulation section 28.

The base end portions of the 43 are rotatably provided above the stacking portions 4.5.6, and the tip portions are connected to the bases 1 to 40 provided below the stacking portions 4.5.6. This is a guide member for banknotes that are held together.

Next, the supply section 3 will be further explained.

In FIG. 5, 50 is a take-in roller, 51 is an eccentric feed roller, and 52 is a gate roller for preventing overlapping, and this gate roller 52 is designed not to rotate. Further, 53 is a pulse motor that drives the take-in roller 50, and the take-in roller 50 is rotated in the direction of the arrow shown in the figure by this pulse motor 53.

The driving force of the take-in roller 50 is transmitted to the feed roller 51 by gears 54a to 54c.
The feed roller 5o is also rotated by the pulse motor 53 in the same direction as the feed roller 5o. The banknotes taken out by the take-in roller 50 and the feed roller 51 are fed into the sorting and sealing machine through the gap between the take-in roller 50 and the gate roller 52.

On the other hand, above the taking-in roller 50, a backup 55 is provided that presses the banknotes stacked in the feeding section 3 in the direction of gravity toward the taking-in roller 50. This backup 55 is moved up and down by a pulse motor 56.

That is, above the side surface of the partition wall 66 provided in the supply section 3,
The pulse motor 56 is provided, and the pulse motor 5
A timing belt 57 is stretched between a pulley 56a provided at the rear wall 6 and a driven pulley 56b provided below the side surface of the partition wall 56. This timing belt 57
A push block 58 is fixed to the timing belt 57, and the push block 58 is guided by a slide shaft 59 disposed along the timing belt 57. Furthermore, a slide block 60 is slidably provided on each of the five slide shafts and is biased toward the lower end of the slide shaft 59 by a coil spring 60a. A shaft 61 with an extended tip is provided on the back surface. This shaft 6
1, a block 63 is rotatably provided at the tip thereof, and the backup 55 is provided on this block 63. Further, bearings 62 and 64 are provided in the intermediate portion of this shaft 61 and the block 63,
These bearings 62 and 64 are movably engaged with substantially inverted long holes 65a provided in the guide body 65, respectively.

Therefore, when the slide block 60 is located at the top, the backup 55 is rotated in the direction of arrow M in the figure to facilitate replenishment of banknotes, and the slide block 60
0 is moved downward, the backup 55 is accordingly rotated in the direction of the arrow N shown in the figure, and is lowered with the backup 55 parallel to the surface of the banknotes placed on the supply section 3. It looks like this.

Further, a slit 66a is formed in the partition wall 66, and a movable element 67a of a remaining amount detection switch 67 provided on the back side of the partition wall 66 projects into the slit 66a. Therefore, when a large amount of banknotes are placed in the supply section 3, the remaining amount detection switch 67 is in an on state.

Further, as shown in FIG. 6, the remaining amount detection switch 67a is attached to the partition wall 66 via an attachment member 68 having a long hole 68a. Therefore, this long hole 68a
By loosening the screw passed through the banknote, the position of the remaining amount detection switch 67 can be changed, and the remaining amount can be adjusted depending on the type of banknote, for example. Furthermore, an upper limit detection switch 70 and a lower limit detection switch 71 for detecting the position of the push block 58 are provided near the push block 58, and the push block 58 is detected by these upper and lower limit detection switches 70 and 71. This allows the location of the backup 55 to be recognized. Further, in the vicinity of the supply section 3, a replenishment switch 69 is provided, and a fitness level switch 72 for setting a fitness determination level is provided.

FIG. 1 shows a backup control circuit. In the same figure, the operating contact of the supplementary switch 69 is grounded, the fixed contact of this switch 69 is connected to the power supply +■ via a resistor 81, and the JK flip 70 tube circuit (hereinafter referred to as J
(abbreviated as K-FF circuit) 82.

The JK input terminal of this JK-FF circuit 82 is connected to the power supply V via a resistor 83, and the set input terminal S is configured to be supplied with an initial signal.

The Q1G output terminal of this JK-FF circuit 82 is connected to a set/reset flip-flop circuit (hereinafter referred to as R8-
(abbreviated as FF circuit) 84 set, reset input terminal S
, R. Further, the JK-FF circuit 82
A signal outputted from the Q output terminal of is supplied to a drive control circuit (not shown) for the take-in roller 50, and when this signal is at a high level, for example, the take-in roller 50 is driven.

On the other hand, the Q output terminal of the R8-FF circuit 84 is connected to the input terminal of an AND circuit 86 via an inverter circuit 85. A resistor 87.8 is connected to the input terminal of this AND circuit 86.
One end of resistor 87 and 88 are connected to the power supply +■, respectively. Also, resistance 87.8
8 are grounded via the remaining amount detection switch 67 and lower limit detection switch 71, respectively. The output terminal of the AND circuit 86 is connected to the motor 56 that drives the backup 55. When a high level signal is output from the AND circuit 86, the motor 56 is rotated in the forward direction, and the backup 55 is driven. It is designed to be lowered.

Further, the Q output terminal of the R8-FF circuit 84 is connected to the input terminals of the eight AND circuits, and is also connected to the power supply +V via a resistor 90. The other input terminal of this AND circuit 89 is connected to one end of a resistor 91.
The other end is connected to the power supply V. One end of this resistor 91 is grounded via the upper limit detection switch 70. The output terminal of this AND circuit 89 is connected to the motor 56 that drives the backup 55, and when a high level signal is output from the AND circuit 89, the motor 5
6 is rotated in the opposite direction, and the backup 55 is raised.

In the above configuration, the operation will be explained.

Normally, the backup 55 is stopped above the supply section 3, the upper limit detection switch 70 is turned on, and the remaining amount detection switch 67 and the lower limit detection switch 71 are turned off. In this state, when a banknote is placed on the supply section 3, the remaining amount detection switch 67 is turned off. In this state, when a start switch (not shown) of the operating section 8 is operated, the taking-in roller 50 is driven to take in bills from the supply section 3, and the JK/FF
An initial signal is supplied to the set input terminal S of the circuit 82, and the JK-FF circuit 82 is placed in the set state. Therefore, the R8-FF circuit 84 is brought into a reset state. At this time, since the input conditions of the AND circuits 86 and 89 are not satisfied, the output signals of the AND circuits 86 and 89 are at a low level, and the motor 56 is not driven. Therefore, when the amount of banknotes placed on the supply unit 3 is large, the backup 55 is not operated and the banknotes are taken in only by their own weight.

In this state, when the taking-in operation progresses and the amount of banknotes placed on the supply section 3 decreases, and the remaining amount detection switch 67 is turned on, the input condition for the AND circuit 86 is established, and the AND circuit 86 A high level signal is output. Therefore, the motor 56 is driven and the backup 5
5 is lowered. Therefore, when the number of banknotes is low, the backup 55 presses the banknotes and takes them in.

On the other hand, in a state where the backup 55 is lowered,
When the supplementary switch 69 is operated, the state of the JK-FF circuit 82 is reversed, and accordingly, the state of the R8-FF circuit 8 is reversed.
4 is reversed from the reset state to the set state. Therefore, the input condition of the AND circuit 86 is not satisfied, and the input condition of the AND circuit 89 is satisfied, and the AND circuit 89 outputs a rehigh level signal. Therefore, since the motor 56 is reversely rotated and the backup 55 is raised, it is possible to replenish bills while continuing to take in bills.

After replenishing the supply section 3 with banknotes, when the replenishment switch 69 is operated again, the state of the JK-FF circuit 82 is reversed and the R8-FF circuit 84 is changed from the set state to the reset state.

Therefore, if a small amount of banknotes is replenished and the remaining amount detection switch 67 remains in the off state, the input condition of the AND circuit 86 is satisfied, and the input condition of the AND circuit 89 is not satisfied. Since a high level signal is output from the circuit 86, the motor 56 is driven in the forward direction and the backup 55 is lowered. Further, when a large amount of banknotes is replenished, the remaining amount detection switch 67 is turned off, so the input condition of the AND circuit 86 is not satisfied, and the backup 55 is not lowered.

In this way, when the banknote taking-in operation progresses and all the banknotes placed on the supply unit 3 are taken in, the backup 55
reaches the lower limit position, and this lower limit detection switch 71
detected by. Therefore, the lower limit detection switch 7
1 is turned on, the input condition of the AND circuit 86 is not satisfied, the output signal of the AND circuit 86 becomes low level, and the motor 56 is stopped.

Further, a detector (not shown) detects that the banknotes are gone from the supply unit 3, and the motor 56 that drives the take-in roller 50 is stopped. In this state, when the supplementary switch 69 is operated, the state of the JK-FF circuit 82 is reversed, and the state of the R3-FF circuit 84 is reversed from the reset state to the set state. Therefore, the input condition of the AND circuit 89 is satisfied, the motor 56 is reversely rotated, and the backup 55 is raised. Then, when the backup 55 reaches the upper limit position, this is detected by the upper limit detection switch 70, the input condition of the AND circuit 89 is determined not to hold, and the motor 56 is stopped.

According to the embodiment described above, when the bills are stacked in the feeding section 3 in the direction of gravity and there are many bills, the backup 55 does not press the bills because the wrinkles and warpage of the bills are corrected by their own weight. That's what I do. Therefore, it is possible to freely add banknotes. Also,
When the remaining amount of banknotes becomes small and the remaining amount detection switch 67 is turned on, the backup 55 is lowered to press the banknotes. Therefore, even when the number of banknotes is small, it is possible to correct the wrinkles and warpage of the banknotes, and it is possible to prevent skew and the like from occurring in the taken-in paper sheets.

Furthermore, even when the banknotes are pressed by the backup 55, if the replenishment switch 69 is operated, the backup 55 is raised, so that banknotes can be added freely, which is extremely convenient in practice. .

Note that this invention is not limited to the above embodiments,
Of course, various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As detailed above, according to the present invention, when the remaining amount of stacked paper sheets is large to a certain extent, wrinkles and warping of the paper sheets are corrected by their own weight. Therefore, by not pressing the paper sheets with the pressing means, it is possible to replenish the paper sheets in this state, and when the remaining amount detection means detects that the remaining amount of paper sheets is low, A paper sheet processing device that operates the drive means and presses the paper sheets with the pressing means, so that the wrinkles and warping of the paper sheets are corrected and the paper sheets can be stably processed down to the last sheet. can be provided.
