DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet processing apparatus for sequentially taking out and transporting stacked paper sheets, performing predetermined processing on the stacked paper sheets, and sorting and stacking them.

[0002]

2. Description of the Related Art Conventionally, a paper sheet processing apparatus sequentially takes out and transports stacked paper sheets, performs an inspection, for example, as a predetermined processing on the stacked paper sheets, and performs processing for re-distributed paper sheets and waste paper. It is used as a device that separates and accumulates for leaves.

[0003] A paper sheet processing apparatus is a device in which collected paper sheets, which are stacked and carried in n sheets (n is an arbitrary constant), are continuously taken out at predetermined intervals one by one at a take out section. Inspection section inspects the paper sheets for damage, etc. while conveying the belt at a high speed in the conveyance section, decides whether to discard or reuse each sheet, and determines the two directions specified by the sorting section. The waste papers and the recycled papers are separately re-stacked.

[0004] Those collected as discarded paper sheets are then shredded. The processing speed of paper sheets is about several tens of sheets per second, and the conveying speed is always constant at several meters per second.
Hereinafter, a conventional example of a paper sheet take-out apparatus mounted on such a paper sheet processing apparatus and sequentially taking out stacked paper sheets will be described.

FIG. 28 is a view showing a schematic configuration of a conventional paper sheet take-out apparatus. In FIG. 28, the flywheel 100 is connected to the rod 10 via a bearing (not shown).
1 and is driven by a motor (not shown) via a V-belt (not shown). Conversion link 102
Is a flywheel 1 through a bearing (not shown).
00 and a conversion link 10 fixed to a crank 105 and a cam 103 fixed to a rod 101.
6 and are slidably connected by cam followers 107 and 108, respectively. The crank 105 is connected to the rod 101 via a bearing 110, and is further fixed to a take-out rotor 111.

The chamber 112 is fixed to the rod 101 so as not to contact the inside of the take-out rotor 111. The frame 113 supports the rod 101 and covers the chamber 112.

With the above mechanism, the flywheel 100
Is converted into an intermittent rotational motion (repeating the operation / stop / operation) by the conversion links 106 and 102 and the cam 103, and transmitted to the take-out rotor 111 via the crank 105. .

The take-out rotor 111 has a hollow cylindrical structure with a hollow inside, and is provided with a rotor suction hole 115 composed of a plurality of through holes on the circumferential surface. This rotor suction hole 115

A groove 116 as a relief for a sensor (not shown) for detecting the position of the upper surface of the stacked paper sheets is provided in a portion of about m and about 1/3 of the center. The size of the rotor suction holes 115 is about φ6 mm, and two rows are provided with the groove 116 interposed therebetween.

In order to increase the coefficient of friction around the rotor suction hole 115, a groove is formed on the circumferential surface of the take-out rotor 111, and a thin rubber plate 117 (hereinafter, referred to as a rubber chip) is attached. The rubber chip 117 is configured to slightly project from the circumferential surface of the rotor 111 and become convex when attached.

The chamber 112 has a cylindrical structure in which one side surface is closed and the other side surface is also closed by a frame 113, thereby having a hollow structure having a cavity therein.
A cutout portion is formed in a part of the circumferential surface of the chamber 112 so as to be connected to the internal cavity, thereby forming a chamber hole 114.

The chamber 112 has a minute gap so that its outer peripheral surface can rotate without contacting the inner peripheral surface of the take-out rotor 111. Chamber 11
2 is provided with a pipe 1 provided in the frame 113.
It is connected to a vacuum pump (not shown) via 18 and is maintained at a negative pressure.

As a result, when the take-out rotor 111 rotates and the rotor suction holes 115 pass through the chamber holes 114, the suction force is exerted, and the friction around the rotor suction holes 115 generates a paper sheet take-out force. Paper sheets can be sequentially taken out one by one. A series of mechanical parts are controlled so that the rotor suction hole 115 can temporarily stop at a position where the rotor suction hole 115 overlaps the chamber hole 114 and can exert a suction force.

00 is detected, and the distance between the take-out rotor 111 and the top surface of the paper sheet 200 is within a certain distance (for example, 1 mm).
The position of the paper feed table 113 is controlled so as to fall within the range.

Further, the paper feed controller 130 controls the timing of the start of taking out by pressing the top surface of the paper sheet 200 by using the stopper 136 connected to the actuator 135.

The chamber hole 114 is provided with the take-out rotor 111
The sheet 200 is opened from the vicinity where the sheet 200 comes into contact with the sheet 200 to a position where the sheet 200 is carried into the transport path 124. Is sucked, accelerated and reaches an arbitrary speed, and is delivered to the transport path 124. Paper sheets 200 taken out
Is transported into the transport path 124 by the take-out rotor 111 and the first rollers 136 arranged in a nest.

Carried to zero. The paper sheets 1 are continuously taken out one by one from the paper feeding device 10 by a take-out device 11 at a predetermined interval, and are fed into a transport path 12. At this time, two or more paper sheets are prevented from being simultaneously taken out by the two-sheet taking prevention device 13 provided opposite to the taking-out device 11.

An inspection unit 4 is arranged in the direction of the surface of the paper sheet 2 above, and inspects the state of the surface of each sheet 1 to check the damage state, the dirt state, and the like.

The stacking unit 6 is divided into one for recirculated paper sheets and one for discarded paper sheets. Based on the result of the inspection by the inspection unit 4, the transport direction of the paper sheets 1 is changed to that for recirculated paper sheets and discarded. It is classified into paper sheets. This sorting process is performed by the facing type sorting gate device 15 provided on the transport path 12.

Used to detect skew and the like.

(Explanation of the Configuration of the Paper Sheet Pickup Apparatus) FIG. 2 shows the schematic configuration of the paper sheet pickup apparatus 11. Chamber 22
Is a hollow cylindrical structure having a cavity formed therein, and a chamber hole 45 (FIG. 1) connected to the internal cavity is formed on the outer peripheral surface of the cylinder.
1) is formed, and the internal cavity is connected to a vacuum pump (not shown) or the like, and is maintained at a negative pressure during the operation of taking out paper sheets.

The take-out rotor 21 has a thin hollow cylindrical structure, has a rotor suction hole 28 penetrating the cylindrical surface, and the chamber 22 is inserted into the hollow take-out rotor 21 concentrically. 21 is the chamber 2
It is rotatably attached to 2 via two bearings 23 and 24. The gap between the inner peripheral surface of the take-out rotor 21 and the outer peripheral surface of the chamber 22 is several tens (μm).
And a structure with little air leakage is adopted.

The bearing 24 has an inner ring fixed to the chamber 22 and the rod 25, and an outer ring fixed to the take-out rotor 21 and the rotor cover 26. On the other hand, bearing 23
The outer ring is fixed to the take-out rotor 21 and the rotor cover 26, and the inner ring can be pressed toward the bearing 24 by the guide 27. The spacer 29 is positioned by the chamber 22 and the bolt 3
0 and fixed by a washer 31.

The Belleville spring 32 disposed between the spacer 29 and the guide 27 is in a compressed state, and the generated elastic force acts on the inner ring of the bearing 23 via the guide 27 in the direction of the bearing 24. ing. As a result, preload can be applied to the bearings 23 and 24 (constant pressure preload), so that the life of the rotating mechanism can be extended. Since this preload amount is determined by the amount of compression of the Belleville spring 32, the spacer 2
9 is determined by positioning the position with respect to the chamber 22 at a predetermined position.

Here, if the bearings 23 and 24 are made to have a clearance fit with the take-out rotor 21 and are fixed by the respective thrust forces of the rotor covers 33 and 26, assembly and disassembly are simplified.

The dust covers 35 and 36 are fixed to the rotor covers 33 and 26, respectively, and slide against the spacer 29 and the rod 25, respectively, to prevent paper dust and the like from entering the bearings 23 and 24. Has become. The rod 25 is vertically fixed to the sub-base 27, so that the entire mechanism (hereinafter referred to as “rotor unit”) for performing the take-out operation including the take-out rotor 21 and the chamber 22 is fixed to the sub-base 25. I have.

The outer peripheral surface of the take-out rotor 21 is provided with two crown portions 38 and 39, and the endless flat belt 4 is provided.
The structure is such that the rotational force is transmitted to the take-out rotor 21 by multiplying the take-out rotor 1 and 42. The outer diameter of the crown portions 38, 39 is such that the winding outer diameter of the flat belts 41, 42 is a concave shape slightly depressed from the diameter of the outer peripheral surface of the take-out rotor 21. It is configured not to directly contact the paper sheet 1.

Therefore, the sheet 1 is taken out and the rotor 21 is taken out.
Thus, there is no problem that the pitch of the paper sheet 1 is uneven or the paper sheet 1 is soiled. The crown portions 38 and 39 are formed by taking the thickness of the flat belts 41 and 42 into consideration.
When the belt 2 is wound around the crown portions 38 and 39, the flat belt 4
1 and 42 are, for example, 0.1 to
It is formed so as to be depressed by about 1 mm.

Further, in order to enlarge the contact portion with the paper sheet 1 around the rotor suction hole 28 and to take out the paper sheet 1 reliably,
Holes are provided on the outer peripheral surface of the take-out rotor 21 at portions corresponding to the rotor suction holes 28. Further, a rubber chip 43 may be attached to this portion.

The rotor suction holes 28 are provided with the crown portions 38, 3
9 (that is, the flat belts 41 and 42) are sandwiched between them, and furthermore, they are also arranged at positions where both ends in the width direction of the paper sheet 1 to be used can be gripped.

(Explanation of Characteristic Features of the Present Invention: Pitch Conversion Method) First, a description will be given of the take-out intervals (pitch and gap) of paper sheets that cause inconvenience in post-processing. In the following figures, description will be made using the pitch, but the same can be applied to the gap.

The take-out pitch that causes inconvenience in post-processing is
Although there are variations depending on the type of the processing device, in the present embodiment, it is a “short pitch” that is a pitch shorter than a reference pitch by a predetermined value or more, or a pitch that may cause the short pitch. The reference pitch is a value (reciprocal) calculated from the take-out speed (number of paper sheets / second).

With reference to FIGS. 3 and 4, types of short pitches that may cause inconvenience in post-processing will be described along the causes. As shown in FIG. 3, when an arbitrary sheet is removed at a timing later than the reference for some reason, the distance between the sheet to be extracted and the sheet that has already been extracted before that is removed. The pitch is a long pitch. And
When the next paper sheet to be taken out is taken out according to the standard, the pitch between the taken out paper sheet and the next paper sheet becomes a short pitch. The short pitch generated in this manner is referred to as “expectant short”.

Thereafter, if the succeeding sheet is taken out according to the reference, the following steps are taken out at the reference pitch. Among the expected shorts, those shorter than the reference pitch by n1 or more are referred to as “prohibitive shorts”, and the others are referred to as “permissible shorts”. The value of n1 naturally depends on the type of processing device. If n1 = 0, there is no permissible short.

Permissible shorts do not cause any problems in post-processing if they are left as they are, but they are more likely to be changed to prohibitive shorts due to disturbances in the transport section than other pitches. Is good.

The long pitches having a possibility of causing the short pitches as described above are referred to as “prohibitive long” and “permissible long”, respectively. This will be described later with reference to FIG.

Next, as shown in FIG. 4, if an arbitrary sheet is taken out earlier than the standard for some reason,
Regardless of the previous pitch, the pitch between the sheet to be removed and the previous sheet may suddenly become a short pitch, which is referred to as "abrupt short".

The cause may be that the paper sheets are taken out due to the insufficient stopping effect of the two-sheet taking prevention device. When the next sheet following the Abrupt Short is taken out as standard, the next pitch after the Abrupt Short becomes a long pitch. This long pitch does not cause a problem in post-processing. After that,
If the following sheet is taken out according to the standard, the following is the standard pitch.

As in the case of the expectant short,
Of the Abrupt Shorts, those shorter than the reference pitch by n1 or more are referred to as "Prohibitive Shorts", and the others are referred to as "Permissible Shorts".

The permissible long will be described with reference to FIG. As shown in the figure, there are two types of “permissible long”, one that includes an empty swing and one that does not.
Missed swing is the removal speed (number of paper sheets /
Seconds), do not take out as many sheets as you can. For example, if only one sheet is taken out during the period when two sheets should be taken out, the missed swing 1
Expressed as times.

Among the permissible longs, the one that is not missed occurs when an arbitrary sheet is picked up with a delay longer than the reference pitch by a value smaller than n1. Then, if the next sheet after the sheet to be taken out is taken out according to the standard, an expectant short (permissible short) occurs. If there is a missed sheet, take out any sheet and swing it out, and when the next sheet is taken out according to the standard, the pitch between the sheet to be taken out and the next sheet will be permission. This is the pitch between the paper sheet having the longest pitch that causes a double short and the previous paper sheet. Naturally, the pitch between the sheet to be taken out and the next sheet is longer than the permissible short.

FIG. 6 shows a short pitch conversion concept according to the present invention in the case where the extraction timing of the extraction means (extraction device) is not changed, and these will be described below.

That is, the pitch conversion includes a method of changing the take-out timing of the take-out means (take-out device) and a method of not changing the take-out timing. The case of changing the take-out timing will be described separately later because the conversion is simple.

In the case of the prohibitive short, as described above, it is difficult to classify and accumulate the post-processing. Therefore, as shown in FIG. 6, it is necessary to convert the pitch into a pitch that allows easy post-processing such as a permissible short.

Next, the conversion (a) shown in FIG. 6 using FIG.
Will be described. As shown in FIG. 7, if taking out the conversion target sheet as it is would result in the removal of a prohibitive short, the conversion target sheet is controlled and taken out, so that a permissible long or Convert to Permissible Short or Continuous Permissible Short. However, in the case of conversion into continuous permissible shorts, the paper after the above-mentioned paper to be converted may also be controlled (to be a paper to be converted).

In order to convert a prohibitive short into a permissible short, it is sufficient to perform control so that the missed shot is performed at least once. To convert a prohibitive short into a permissible short, a sheet to be converted is used. It is sufficient to control so as to take out the papers with a delay, and to convert the prohibitive short into continuous permissible shorts, it is sufficient to control to take out a plurality of sheets to be converted with a delay.

In any case, this conversion does not cause the subsequent pitch to become a prohibitive short. Further, since the expectant short is inevitably generated after the long pitch, it is always predictable, and the preparation for conversion can be started in advance when the prophylactic long is detected.

Next, the conversion (b) shown in FIG. 6 will be described with reference to FIG. As shown in FIG. 8, if the conversion target sheet is taken out as it is, a prohibitive short is taken out. As in the case of the above-described expectant short, the conversion target sheet is taken out. By controlling, it can be converted to permissible long,
The pitch is converted to a pitch between the permissible short and the permissible long (no swing).

In order to convert a prohibitive short into a permissible long, it is sufficient to perform control such that the missed swing is performed at least once.
In order to convert the pitch into a pitch between, the sheet to be converted may be controlled so as to be taken out with a delay.

In any case, this conversion does not cause the subsequent pitch to become a prohibitive short. Next, the conversion (c) shown in FIG. 6 will be described with reference to FIG.

As shown in FIG. 9, if the sheet to be converted is taken out as it is, a protractive long sheet is taken out, and the sheet following the sheet to be converted is taken out according to the standard. Then, the next pitch becomes a prohibitive short. Therefore, the prohibitive long is converted into the permissible long by controlling the removal of the conversion target sheet. The conversion from the prohibitive long to the permissible long can be achieved by performing at least one missed swing. As a result, the subsequent pitch does not become a productive short.

In the above description, an example in which the miss swing is performed once is shown, but it is needless to say that the miss swing may be performed a plurality of times. The expectant short is a short pitch that occurs after the long pitch. Even if the long pitch itself is not detected, “missing” and “possibility of missing” of the paper sheet are performed.
Is detected, the result is equivalent to the detection of a long pitch, and pitch conversion can be performed using the result.

Further, since the initial short occurs in the leading sheet, the long pitch between the sheet and the preceding sheet does not occur. Therefore, it is necessary to predict not the method of detecting the long pitch but the fact that the sheet before forming the pitch is "missing" or "expected to be missing".

Here, in order to predict the failure, it is necessary to detect various removal state parameters of the paper sheet.
The take-out state parameters include, for example, the relationship between the tip of the sheet and the rotation position of the take-out rotor (sheet take-out position based on the slip amount of the sheet), the sheet take-out pressure (negative pressure in the chamber). And a pressing force of the paper sheet against the take-out rotor.

FIG. 10 shows a conversion method for changing the take-out timing. If taking out the conversion target sheet as it is would result in the removal of the prohibitive long, even if the conversion target sheet is taken out as it is, it will be used after the next sheet after the conversion target sheet. By changing the take-out timing, the occurrence of a prohibitive short can be prevented. In other words, the timing is changed once so that the sheets to be taken out thereafter return to the reference pitch even if the prohibitive long occurs, and thereafter, the reference pitch is taken out sequentially based on the changed timing. Just do it.

The example shown in FIG. 10 relates to an expectant short. However, the example shown in FIG. In the paper sheet processing apparatus according to the present embodiment, the conversion is performed by the extraction unit as described above, but, of course, the conversion may be performed by another part as long as the condition that the paper sheet does not come later is satisfied. .

The prohibitive short can be eliminated by the above-described pitch conversion method. A method for realizing this and a specific configuration and a method for converting skew using the same will be described below.

The skew is the inclination of each sheet taken out and conveyed with respect to the traveling direction. for that reason,
Unlike the pitch, there is no relative relationship with other paper sheets, and therefore, it is possible to perform the processing at a portion other than the take-out unit without being restricted by the above-described pitch.

The method of realization and the specific configuration can be roughly classified into the following. (1) Method of switching the magnitude of the take-out force of the take-out means (take-out device): For example, control is performed using an air conditioning unit of a vacuum suction type take-out device. Method. (2) A method by switching the magnitude of the conveying force of the conveying means (conveying unit): a method in which control is performed using, for example, a roller (double gripper method, single gripper method). (3) A method by operating the unloading means: a method of performing control using a movable lever, for example. (4) Method by operating the means for changing the take-out timing of the take-out means: a method of performing control using, for example, a rotor brake.

There are four methods. The specific configurations of the above (1) to (4) will be described in order below. I. (Explanation of (1): Implementation Method and Configuration) FIG. 11 shows the configuration of the sheet processing apparatus takeout unit 2 related to a method of switching the magnitude of the takeout force of the takeout means (takeout apparatus).

The take-out section 2 comprises a paper feeder 10, a vacuum suction type take-out device 11, and a two-sheet take-out prevention device 13. The leading end of the paper sheet 1 is pressed against the take-out rotor 21 with a constant pressing force by the paper feeding device 10, and this pressing force is detected by the pressing force detection sensor 46. Then, the rear end side of the paper sheet 1 from the pressed portion of the paper sheet 1, particularly the vicinity of the SA portion in the drawing, is loosened by blowing air from a nozzle or the like (omitted in the drawing). The loose state of the paper sheet 1 is detected by a loose state detection sensor 55 described later.

The take-out rotor 21 rotates around the chamber 22 at a constant angular speed (constant speed), and its drive is performed via endless flat belts 41 and 42 (not shown).
It is performed by The flat belts 41 and 42 form a system with the take-out rotor 21, the drive roller 48, the idle roller 49, the tension roller (not shown), and the like, and form a conveyance path with other idle rollers, guides (see FIG. 1). .

The rotation speed of the take-out rotor 21 and the rotation position of the rotor suction hole 28 are determined by the fact that the shielding plate 50 attached to the rotor cover 26 crosses the photoelectric sensor 51 (rotor rotation speed and suction hole position detection sensor). It is configured to be detected.

Thus, the sheet 1 is taken out and the rotor 21 is taken out.
By adopting the press-feeding method of pressing the sheet 1, good adhesion between the sheet 1 and the take-out rotor 21 is compensated, so that the attraction force of the take-out rotor 21 is efficiently transmitted to the sheet 1 and is stable. Extraction is possible.

In the drawing, the stacking direction of the paper sheets is vertical, but the direction orthogonal to this (horizontal direction)
And so on. The paper sheet 1 includes a sheet feeding device 10.
After being pressed against the take-out rotor 21, it is sucked and taken out, and is carried into the conveyance path 12 while being guided by the flat belts 41 and 42 and the two-sheet take-up prevention block 52. As before, the sheet 1
Is prevented from being removed more than once. In addition, paper sheets 1
Is positioned on the side surface of the two-sheet taking prevention block 52. The chamber hole 45 is provided in the rotor suction hole 28
When the inner peripheral surface of the tip in the rotation direction of the above overlaps with the chamber hole 45, the position where the outer peripheral surface of the rotor suction hole 28 overlaps with the vertical line drawn from the center point of the take-out rotor 21 (tip)
To a position (rear end) where the paper sheet 1 is peeled off by the flat belts 41 and 42.

However, the leading end may be located closer to the transport path, and the trailing end may be located closer to the take-out side. The position of the rotor suction hole 28 in the circumferential direction is a position where the take-out rotor 21 can grip (grip) the paper sheet 1 until the leading end of the paper sheet 1 is gripped (gripped) by the transport path 12. Immediately after the two-sheet take-out prevention device 13, the entrance of the conveyance path 12
2 is formed by gradually approaching and contacting,
The sheet 1 is gripped at the contact position.

The vacuum suction type take-out device 11 generates a vacuum suction force by making the inside of the chamber 22 negative with respect to the atmospheric pressure. This will be described with reference to FIG. The air conditioning unit 60 is provided for performing intake and exhaust in the chamber 22 and controlling the pressure in the chamber 22, and the state of intake and exhaust is controlled by the control device 61.

The air-conditioning unit 60 is air-tightly connected to a vacuum pump 67 and the like as will be described later, an electromagnetic valve 69 interposed in the middle of the air-flow path 75, and a compressor 68 and the like. Exhaust path 76 and this exhaust path 7
6 comprises an electromagnetic valve 69 and the like interposed in the middle. In the configuration shown in FIG. 10, these air conditioning units 60 are attached to the chamber 22.
2 may be used.

The control device 61 includes a pressing force detection sensor 46,
It is provided so that output signals of the rotor rotation speed and suction hole position detection sensor 51, the loosening state detection sensor 55, and the take-out pitch detection sensor 56 can be input. That is,
The air conditioning unit 60 is controlled using these signals.

Hereinafter, an example of controlling the take-out force of the vacuum-suction type take-out device 11 using the air-conditioning unit 60 and the control device 61, and an example of pitch conversion based on the control will be described. However, the time from the input of the operation signal to the operation of the air conditioning unit 60, that is, the operation delay of the air conditioning unit 60 is t0.

In FIG. 13A, a jam (paper jam) occurrence signal from the take-out pitch detection sensor 56 or the like is t = t
As soon as the signal is input to the control device 61, a signal for closing the solenoid valve 69 of the air conditioning unit 60 is output from the control device 61. By such control, when a paper jam (paper jam) occurs, the negative pressure in the chamber 22 is immediately released. By performing such jam handling control, unnecessary suction and unloading can be stopped.

In FIG. 13B, when an arbitrary prohibitive long occurs, before the rotor suction hole 28 next passes through the chamber hole 45 (that is, before the next sheet is taken out), At timing t4 when the negative pressure in the chamber 22 is reduced (turned off), the intake path 7 of the air conditioning unit 60 is
A signal for closing the sixth electromagnetic valve 69 is output from the control device 61.

Then, a signal for opening the electromagnetic valve 69 of the suction passage 76 of the air conditioning unit 60 is output from the control device 61 at a timing t5 when the rotor suction hole 28 finishes passing through the chamber hole 45 after t0.

By such control, it is possible to prevent the occurrence of the prohibitive short. Although the configuration example relating to the vacuum suction type take-out apparatus has been described above, the present invention is naturally applicable to other take-out methods other than the vacuum suction type.

In addition to the method described above, the pitch conversion as described above can be performed by using a means for applying a take-out force and a means for controlling the take-out force. II. (Explanation of (2): Implementation Method and Configuration) (2) -1 Double Gripper System FIG. 14 shows the configuration of the sheet processing apparatus take-out unit 2 of the double gripper system.

For the sake of simplicity of explanation, the same device as the take-out device shown in FIG. 11 is used, but it is a matter of course that the present invention is not limited to the vacuum-suction type take-out device. This is true for the following general description.

In FIG. 14, the transport path 12 is composed of a plurality of transport rollers 63 and 66, and the paper transport is performed by using two pairs of transport operations of the first transport roller 63 and the second transport roller 66. Since pitch conversion of class 1 is performed, the description will be given below by referring to the “double gripper method”.

The initial position of the leading end of the paper sheet 1 is determined by the two-sheet taking prevention device 1 when the paper sheet 1 is stacked on the sheet feeding device 10.
3 from the side surface position P1 to the transport path entrance P2 formed by the first transport roller 63 and the flat belts 41 and 42 facing each other. for that reason,
The distance L is set to be shorter than the allowable take-out pitch error. If the position where the flat belts 41 and 42 and the second transport roller 66 are in opposition to each other is P3, P2
The distance between P3 and P3 is configured to be L1 corresponding to the value of the allowable pitch error.

The first transport roller 63 contacts (gripping) and separates (separates) the sheet 1 to be taken out.
It is configured as a switch roller that performs a switching operation by switching operations. The contact and separation operations can be mechanically easily realized using an existing drive mechanism combining a cam mechanism and a link mechanism. The drive timing is synchronized with the take-out timing of the sheet 1, that is, the rotation timing of the rotor suction hole 28 of the take-out device 11 of the present embodiment, and the above-described cam, link mechanism, etc. It is achieved by doing.

However, the distance that the sheet 1 can be conveyed when the first conveying roller 63 is in contact with the sheet 1 is L2, and the sheet 1 is gripped when the sheet 1 is gripped for the n1 (see the conversion concept) time. If the transportable distance is L3, L1 ≦ L2-L
It is configured to be 3. The configuration in which the transport path 12 is formed from the first transport roller 63, the second transport roller 66, and the flat belt as described above is referred to as a double gripper as described above.

Next, the pitch conversion operation of the double gripper method will be specifically described with reference to FIGS. FIG.
The first transport roller 63 contacts the flat belts 41 and 42 at such a timing that the first transport roller 63 transports the paper sheet 1 only when the paper sheet 1 is removed at the reference pitch, until the next removal timing. It is the figure which showed a mode that it was separated.

Therefore, after the sheet 1 taken out with a delay of the reference timing or the allowable error is conveyed by the distance L2, the second conveyance roller 63 is released when the grip is released by the first conveyance roller 63. Since it is gripped by 66, it is transported at the same pitch.

FIG. 16 shows a case where the sheet 1 is taken out at a timing preceding the reference. The first transport roller 63 does not grip the paper sheet 1 until the reference timing comes, so the paper sheet 1 is converted to the reference timing and taken out. As a result, the profitable short can be converted to the reference pitch.

FIG. 17 shows a case where the sheet 1 is taken out at a timing later than the allowable value n1. Since the first transport roller 63 does not grip the paper sheet 1, the paper sheet 1 is not transported. Then, at the next timing, the sheet is gripped and transported by the first transport roller 63. Thereby, the prohibitive long can be converted into the permissible long.

As described above, the double gripper method is a method of performing pitch conversion without being based on detected pitch data. (2) -2 Single gripper method FIGS. 18 and 19 show the single gripper method.
2 shows a configuration of the sheet processing apparatus take-out unit 2. For the sake of simplicity of explanation, the same device as the take-out device shown in FIG. 11 is used, but it is needless to say that the take-out device is not limited to the vacuum suction type take-out device.

Referring to FIG. 18 and FIG.
Is composed of transport rollers 71, and the transport rollers 71
Is used to convert the pitch of the paper sheet 1, so that
The description will be made with reference to a “single gripper method”.

The transport roller 71 is configured as the switch roller capable of switching between contact and separation with the flat belts 41 and 42, and detects the take-out pitch of the paper sheet 1 by the photoelectric sensor 19. Can be freely operated so as to correct.

As described above, since the pitch control of the paper sheet 1 is performed using the transport roller 71 as a switch roller, it is called a single gripper system. However, when the grip of the transport roller 71 is released, the transport is more stable when controlled to grip the transport roller 65.

As shown particularly in the figure, a switch roller (transport roller) 71 is connected to an actuator 75 (for example, a rotary solenoid) via a support base 73, and can contact or separate from the flat belts 41 and 42. . Further, the operation may be stabilized by pressing the switch roller (conveying roller) 71 toward the flat belts 41 and 42 with a predetermined force by the spring 74.

Next, FIG. 20 shows an example of the configuration of a switch roller for skew correction for a single gripper. The take-out device 11 may be arranged in the same manner as the pitch-correcting switch roller 71. However, as shown in FIG. 20, individual switch rollers (transport rollers) 81 and 82 are provided, and these switch rollers (transport rollers) are provided. A configuration in which actuators 83 and 84 are provided corresponding to the rollers 81 and 82, respectively, and the switch rollers (transport rollers) 81 and 82 can be driven independently and independently by these actuators 83 and 84, respectively. Accordingly, the sheet 1 can be inclined toward the side of the switch rollers (conveying rollers) 81 and 82 to which the sheet 1 is gripped first.

By controlling the contact or separation of the switch rollers (conveying rollers) 81 and 82 with the sheet 1 in this manner, it is possible to perform skew correction when the sheet 1 is taken out. .

Next, FIG. 21 shows an outline of an example of the arrangement of the switch roller guide (suction type). When pitch conversion is performed using the above-described double gripper or single gripper method, there is a possibility that the sheet 1 does not stop at a predetermined position depending on the method of the take-out device and the take-out speed.

In order to prevent such inconvenience, a suction guide 91 may be provided so as to be nested with the switch rollers 63, 71, 81, and 82, and the sheet 1 may be surely stopped. . The suction surface of the suction guide 91 is arranged at a distance of about several mm from the transport path 12. As the suction method, a method utilizing a vacuum suction force is effective, similarly to the two-sheet removal prevention device 13.

FIG. 22 shows an example of the arrangement of a suction guide 91 utilizing the above-mentioned vacuum suction force. The suction guide 91 has a chamber structure similar to that of the above-described chamber 22, and includes a pipe 93.
Is connected to a vacuum pump or the like. In addition, the function of the guide 91 may be provided to the two-sheet taking prevention device 13.

FIG. 23 shows an arrangement example using a rotary roller type stopper for a switch roller. If the above-mentioned switch roller (conveying roller) 71 is separated from the flat belts 41, 42, etc., the switch roller (conveying roller) 71
Such rotations decelerate over time. For this reason, it takes time from contact with the flat belts 41 and 42 to catching up with the transport speed, and in some cases, a grip / transport failure period occurs.

Therefore, as shown in FIG. 23, at a position where the switch roller (conveying roller) 71 and the like are separated from the flat belts 41 and 42 and the like, the rotating roller 96 that rotates at the same speed as the conveying speed in the direction opposite to the conveying direction. Configure to make contact. In particular, when the roller 96 is used for a single gripper, the roller 96 has a role of a stopper, and is referred to as a rotating roller type stopper.

FIG. 24 shows an outline of an example of a gate structure configuration using a transport guide. FIG. 24A shows a movable gate 501 and a fixed gate 502 in which the switch roller 71 is in contact with the conveyor belts 41 and 42 and forms a gate structure.
Are separated from each other. The gates 501 and 502 also serve as conveyance guides, and can convey the taken out paper sheets 1. On the other hand, in FIG. 24B, the switch roller 71 is separated from the transport belts 41 and 42, the movable gate and the fixed gate are closed, and the paper sheet 1 cannot be transported.

FIG. 25 shows details of the gate structure. FIG.
As shown in FIG. 7, the movable gate 501 has a structure rotatable by an actuator (for example, a rotary solenoid) 503 connected by a rotation shaft 504. Then, the conveyor belts 41 and 42 are nested and stopped at a fixed gate 502. Of course, both gates may be arranged in reverse.

By using such a gate structure, it is possible to more reliably perform the pitch conversion using the above-described switch roller 71 and the like. The embodiment of the invention relating to the gripper described above is effective not only in the take-out section but also in any sheet processing apparatus in general, and can be applied to any roller of the sheet processing apparatus as long as the conditions are matched. .

In addition to the above-described method, if the means for applying the conveying force to the paper sheet 1 and the means for controlling the same are used, the pitch conversion as described above can be performed.
III. (Explanation of (3) above: implementation method and configuration)
FIG. 26 shows a schematic view of a lever structure which is a reverse take-out means provided in the sheet processing apparatus take-out section 2.

As shown in the figure, the reverse take-out means comprises a lever 511 and an actuator (for example, a rotary solenoid) 512 for rotating the lever. Actuator 512 is operated by a control device (not shown).
The control device can detect pitch and skew data.
The lever 511 has a nested structure with the take-out rotor 21 which is a component of the take-out device 11. The take-out rotor 21 can be configured in various ways such as a vacuum suction system or a friction roller, and the nest structure can be configured inside or outside the rotor 21.

FIG. 26 (a) shows a state in which the lever 511 is separated to a position where the anti-removal force does not sufficiently act on the paper sheet 1, and FIG. In this state, contact is made to a position where the anti-extraction force sufficiently acts. Further, in the drawing, the lever 511 has a structure in which the paper sheet 1 can be sandwiched between the lever 511 and the suction surface of the two-sheet removal prevention device 13 therebetween.

By switching the states (a) and (b) based on the pitch data using a control device (not shown), the above-described pitch conversion can be performed using the lever 511.

The lever 511 and the actuator 512 extend in the direction of the rotation axis of the rotor 21 (the direction perpendicular to the figure).
Are arranged so as to be individually operable, and using a control device (not shown), each of (a)
By switching the state of FIG.
11 can be used to perform skew conversion.

In addition to the above-described method, the pitch conversion as described above can be performed by using a means for applying a counter-ejection force to the paper sheet 1 and a means for controlling the same. I
V. (Explanation of (4): Implementation Method and Configuration) FIG.
FIG. 7 shows a means for changing the take-out timing of the take-out means provided in the sheet processing apparatus take-out section 2.

The means for changing the take-out timing comprises a brake friction member 521, a brake body 522, an actuator (for example, a linear actuator) 523 for operating the brake body, and a control device (not shown) for operating the actuator 523.

The take-out means is constituted by a take-out device 11 having a take-out rotor 21. The brake body 522 is moved by the actuator 523 to the rotor 21.
The brake friction member 521 is pressed against the rotor 21 when approaching, and the rotation timing of the rotor 21 can be delayed. By operating such a brake structure based on the pitch data using a control device (not shown), the pitch conversion as described above can be performed. In the present embodiment, the configuration example using the friction brake is shown, but a method using an electromagnetic force brake is also possible.

There are various methods (not shown) for changing the take-out timing of the rotor 21 in addition to the method of applying the rotation preventing force as described above. For example, an inertia member that rotates at a lower speed than the rotor 21 and is detachable from the rotor 21 and a control device that operates the operation are provided. With such a configuration, when the inertial member is connected to the rotor 21, the speed is reduced as compared with the case of the rotor 21 alone, so that the rotation timing of the rotor 21 can be changed. With such a structure, the pitch conversion as described above can be performed.
