DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus and a paper sheet transport processing apparatus, for example, an automatic teller machine (CD), an automatic teller machine (ATM) and the like. The present invention relates to a sheet separating mechanism for separating sheets one by one and sending the sheets to a conveyance unit.

[0002] For example, when counting and appraising bills such as banknotes in an ATM or the like, they are separated one by one from a stack of stacked bills and sent to a transport unit. At this time, the sheet separating mechanism repeats the feeding operation and the stop based on the passage information output from the passage detection sensor.

[0003] When fed out of the separation mechanism, paper sheets are usually fed out one by one and arranged in a direction parallel to the transport direction. However, the paper may be fed out of the separation mechanism in a state different from the steady state due to variations in paper sheets, errors in the separation mechanism, and the like.

For example, the direction of the fed sheets is oblique to the transport direction (hereinafter referred to as skew), or a plurality of sheets overlap (hereinafter referred to as double feed), They are overlapped in a slightly shifted state (hereinafter referred to as a chain).

If the paper fed from the separation mechanism in an ATM or the like is different from the steady state, counting and appraisal become impossible, and the operation is interrupted. Therefore, there is a demand for the development of a separation mechanism having various monitoring mechanisms that can detect paper sheets different from the steady state at an early stage.

[0006]

2. Description of the Related Art FIG. 8 is a view showing a conventional sheet separating mechanism, FIG. 9 is a plan view showing a conventional skew detecting mechanism, and FIG. 10 is a view showing a conventional thickness monitoring mechanism.

In FIG. 8, a conventional separating mechanism 2 for separating sheets 1 one by one is swung by a plurality of sets of feed rollers 22 rotating together with a drive shaft 21 and a rotating shaft 23 having one end parallel to the feed rollers 22. It comprises a plurality of movably supported separator supports 24.

A separator support 24 having at least one separator 26 fixed in the vicinity of the front end has a bearing 25 at an intermediate portion. It is configured to abut against.

When the bearing 25 comes into contact with the feed roller 22, the separator 26 engages with the groove of the feed roller 22 through an appropriate gap, and the sheet 1 fed by the preceding pick roller 28 Each sheet is separated and sent to the bearing 25.

The bearing 25 forms a gap between the feed roller 22 and the separator 26 through which the paper sheet 1 can pass, and presses the paper sheet 1 against the feed roller 22 by the action of a spring 27 to form a paper sheet. The leaf 1 is easily fed out.

A passage detection sensor 3 comprising a light source 31 and a photodetector 32 facing each other is disposed between the separation mechanism 2 and the conveyor belt 29. When passing through the space between the detectors 32, the light beam 33 is blocked, and the passage of the paper sheet 1 is detected.

The feed roller 22 and the pick roller 28 are intermittently driven in order to prevent the sheets from being overlapped during the conveyance.
Is controlled by using a signal output from the passage detection sensor 3 as a trigger.

If the signal is not output from the passage detection sensor 3 even after a predetermined time has elapsed after the start of the roller, the start and stop are repeated a plurality of times. And an alarm signal or the like is output.

As shown in FIG. 9, a pair of skew detection sensors 34 are provided on both sides of a conveyance belt 29 for conveying the paper 1 as a skew detection mechanism. If 1 is not skewed, a signal is output almost simultaneously from the pair of skew detection sensors 34.

However, when the sheet 1 conveyed by the conveyor belt 29 is skewed when crossing the pair of skew detection sensors 34, the timing of the signal output from each skew detection sensor 34 The skew of the paper sheet 1 can be detected because of the deviation.

However, a double feed or a chain of the sheets 1 cannot be detected by the passage detecting sensor 3 or the skew detecting sensor 34. Therefore, the thickness monitoring mechanism 4 shown in FIG.
It is located in the middle of 29.

That is, in FIG. 10A, the thickness monitoring mechanism 4 includes a potentiometer 41 and a rotating shaft of the potentiometer 41.
A lever 43 is fixed to 42. A movable roller 44 disposed between the transport belts 29 is rotatably fixed to one end of the lever 43.

The movable roller 44 is transported by a spring 46 by a transport belt.
The paper sheet 1 that has been conveyed is pressed by a driving roller 47 and a pressing roller 48 with a movable roller 44 and a fixed roller.
Sent between 45.

When the sheet 1 is fed between the movable roller 44 and the fixed roller 45, the lever 43 is moved in accordance with the thickness of the sheet 1.
Causes the rotation shaft 42 to rotate, and a signal corresponding to the thickness and time of the paper sheet 1 is input from the potentiometer 41 to the thickness detector 49 as shown in FIG.

A preset reference voltage for determining the number of sheets 1 is input from an external control device to the thickness detecting section 49, and a signal input from the potentiometer 41 is compared with the reference voltage. Thus, the number of sheets 1 can be determined.

Also, the signal input from the potentiometer 41 differs between when the sheet 1 has a double feed and when it has a chain. Therefore, the rise of the signal,
Alternatively, the double feed and the chain can be distinguished from each other by the shape difference of the falling edge.

[0022]

However, in the conventional sheet separating mechanism, an independent skew detecting mechanism and a thickness monitoring mechanism are respectively provided in the middle of the transport belt, and the sheet is disposed inside the ATM or CD. This requires a space for installing a separation mechanism, a skew detection mechanism, and a thickness monitoring mechanism, which increases the size of the apparatus.

Further, since the separation mechanism is separated from the skew detection mechanism and the thickness monitoring mechanism, a time lag until a double feed or a chain is detected is large. Sheets are sent from the separation mechanism to the transport belt.

Further, in the conventional paper sheet separating mechanism, the amount of engagement when the separator is fitted into and engaged with the groove of the feed roller is constant. If the leaves are stuck, a non-feed will occur and the device will stop.

Also, when the paper sheets to be handled include bent or wrinkled ones such as distribution tickets, the friction coefficients are different from each other. When an ATM or CD is installed near the entrance of the building, The coefficient of friction varies depending on the installation environment such as temperature and humidity.

As a result, when the state of the paper sheet is different from that at the time of setting the bite amount and the friction coefficient or the like changes due to wrinkles or moisture absorption, it is impossible to separate the paper sheets one by one. As a result, non-feeding or double feed occurs, and the apparatus stops.

An object of the present invention is to provide a separation mechanism which can be provided with various monitoring mechanisms which can detect paper sheets different from the normal state at an early stage and which can reduce the size of the apparatus.

[0028]

The sheet separating mechanism of the present invention comprises a signal processing unit having means for detecting the thickness and skew of the sheet. The time lag until the device stops is small because of detection of chains and chains. That is, it is possible to realize a separation mechanism that includes various monitoring mechanisms that can early detect a sheet different from the steady state and that can reduce the size of the apparatus.

In FIG. 4, a second embodiment of the separating mechanism according to the present invention is swingable by a plurality of sets of feed rollers 22 rotating together with a drive shaft 21 and a rotating shaft 23 having one end parallel to the feed rollers 22. And a plurality of separator support portions 24 supported by the support member.

A separator support 24 having at least one separator 26 fixed in the vicinity of the front end has a bearing 25 at an intermediate portion. It is configured to abut against.

When the bearing 25 comes into contact with the feed roller 22, the separator 26 engages with the groove of the feed roller 22 through an appropriate gap, and the sheet fed by the preceding pick roller 28 is one sheet from the bottom of the bundle. Each is separated and sent out to the bearing 25.

The bearing 25 forms a gap between the feed roller 22 and the separator 26 through which the sheets can pass, and the sheets 25 move the sheets by the action of the spring 27.
To facilitate feeding of paper sheets by the feed roller 22.

However, unlike the separation mechanism shown in FIG.
In this embodiment, an actuator 82 for correcting the amount of engagement between the feed roller 22 and the separator 26 in accordance with a command from the computer 7 is provided between a support member 81 for fixing the bearing 25 and the separator support portion 24.

A support member 81 for fixing the bearing 25 is swingably supported by a rotary shaft 83 fixed to the separator support portion 24. When a voltage is applied from a control device 84 according to a command from the computer 7, the actuator 81 is actuated. 82 extends and pushes up separator 26.

Although a piezoelectric element that expands when a voltage is applied and pushes up the separator 26 is used as the actuator 82, an element that shortens when a voltage is applied, such as a magnetostrictive element or a solenoid, is used instead of the piezoelectric element. Even when used, the same effect can be obtained.

A passage detection sensor 3 comprising a light source 31 and a photodetector 32 is disposed between the separation mechanism and a conveyor belt 29 (not shown). When a sheet passes through the passage detection sensor 3, a light beam 33 is transmitted. And a signal indicating passage of the paper sheet is input to the computer 7.

When a feed signal is input within a predetermined time after the feed roller 22 or the pick roller 28 is operated as shown in FIG. 6, the computer 7 passes the pass detection sensor 3 until a predetermined number of sheets are fed out. A roller drive command is output using the signal as a trigger.

However, the feed roller 22 and the pick roller
If the passage signal is not input within a predetermined time after the operation of the controller 28, it is determined that the sheet is not fed, and the controller 84 outputs an actuator expansion / contraction command to input a predetermined voltage command value for correcting the bite amount of the separator 26 to the control device 84.

After correcting the occlusal amount of the separator 26, the computer 7 outputs a roller drive command for operating the feed roller 22 and the pick roller 28. When a passing signal is input within a predetermined time after the operation, the computer 7 removes the passed paper sheets. Outputs the command and the actuator recovery command.

If the passage signal is not input within a predetermined time after the operation of the roller even after the occlusion amount of the separator 26 is corrected, the actuator expansion / contraction command is repeatedly output until the passage signal is input, and the correction amount is sequentially increased. Each time a roller drive command is output.

If a pass signal is not input even though the amount of expansion and contraction of the actuator 82 has reached the limit value, it is determined that discharge is impossible, and the computer 7 outputs an alarm signal, for example, to indicate that discharge is impossible. To the operator.

As described above, the paper sheet separating mechanism of the present invention, which includes the actuator for correcting the amount of engagement between the feed roller and the separator in accordance with the instruction of the computer between the support member for fixing the bearing and the separator support portion, is provided. ,
Automatic discharge becomes possible, for example, when a sticky substance is interposed or wet with water and a plurality of paper sheets are stuck.

For example, ATMs and CDs are often installed near entrances, and the coefficient of friction of paper sheets such as bills depends on the humidity of the installation environment. To address this situation, FIG.
In the example shown in (a), a humidity sensor for detecting the humidity of the installation space is used as the sensor 9.

When the humidity data is input from the sensor 9 as shown in FIG. 7 (b), the computer 7 calculates a correction amount of the bite amount of the separator 26, outputs an actuator expansion / contraction command, and corrects the bite amount of the separator 26. Is input to the control device 84.

Further, the coefficient of friction of paper sheets that are crumpled or wet paper sheets, such as a circulation ticket, is larger than that of newly issued paper sheets. In order to cope with such a situation, the example shown in FIG. 7C uses a torque sensor for measuring the rotation torque of the motor as the sensor 9.

That is, the sensor 9 is disposed between the pick roller 28 for feeding paper sheets to the separation mechanism and the motor 30 for driving the pick roller 28, and a torque value is input from the sensor 9 as shown in FIG. Then, the computer 7 calculates the frictional force applied to the paper sheet.

The computer 7 further compares the calculated friction force with the friction force in the standard state to calculate a correction amount of the bite amount of the separator 26, and outputs an actuator expansion / contraction command to correct the bite amount of the separator 26. A predetermined voltage command value is input to the control device 84.

Further, in the example shown in FIG. 7E, a current sensor for measuring the current of the motor 30 for driving the pick roller is used as the sensor 9, and as shown in FIG. When input, the computer 7 first starts the motor 30
Is calculated.

The computer 7 calculates the frictional force applied to the sheets by the pick roller 28 from the calculated rotation torque of the motor 30, calculates the amount of correction of the amount of bite of the separator 26, and outputs an actuator expansion / contraction command. A predetermined voltage command value is input to the control device 84.

As described above, the paper sheet separating mechanism of the present invention comprising the actuator for correcting the amount of engagement between the feed roller and the separator in accordance with a command from the computer between the supporting member for fixing the bearing and the separator supporting portion is provided. ,
Even when the condition of paper sheets is changed due to wrinkles or moisture absorption and the friction coefficient changes, etc., when the bite amount is set, it is possible to feed out paper sheets one by one without generating non-feed and double feed Become.
