Abstract

PURPOSE:To surely sort sheets into a stack consisting of a prescribed number of the sheets, by providing a hindering section on a separator having a receiving portion for receiving the sheet pulled out of an impeller, so that the hindering section prevents a sheet previously pulled out of the impeller, from entering onto the receiving portion. CONSTITUTION:When every one hundred sheets are to be sorted and stacked, the front edge of one-hundred-first sheet P1 inserted int the space 11a between blades 10a, 10b comes into contact with the left end face of a support plate so that the sheet stops rotating. As a result, the sheet P1 gradually moves out of the space 11a and finally out of it completely. At that time, separators 21a, 21b are rotating as the center line R of an arm 22 is located just beside the tip Q of the blade 10b and rotated, the one-hundred-first paper P1 having gone out of the space 11a does not drop down but is received and stopped by the receiving tooth 24 of the separator 21a, 21b. At the same time, the hindering section of the separator 22 prevents the hundredth sheet having previously gone out, from entering onto the receiving tooth 24. As a result, both the sheets are completely separated from each other.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paper sheet collection device that divides paper sheets fed in one by one into stacked layers of a certain number of sheets and sends out the stacked layers one after another.

[Technical background of the invention]

For example, various forms of processing of paper documents such as banknotes, data cards, and printed matter have been automated, but as the number of these documents has been increasing in recent years,
It is strongly desired that the machines that perform all of these processes also be faster.

Among these demands, for example, for things such as banknotes, there is a task of storing a fixed number of banknotes in so-called bundles by tying them together in bands or the like. In such work, it is extremely inefficient to manually sort paper sheets into a fixed number of sheets. For this reason, usually an automated process is used to divide the sheets into stacked layers of a fixed number, and then each stacked layer is bound with a band. In such an automated machine, it is possible to continuously stack all the paper sheets that are transferred one by one at high speed without interrupting the transfer, and in the stacking process, it is possible to separate the sheets by a certain number of sheets. It is considered an ideal classification to be achieved.

Conventionally, as a means of accumulating under such conditions, there is a direction change called the "beat method" in which paper sheets are sent out from the end of the conveyance and are struck from above while they are floating in the air, causing them to fall. There is a method of accumulating using means. However, in such a stacking means, there is a limit to the high-speed response of the sheet direction changing means. In other words, when the direction conversion means is vibrated within a certain amplitude at high speed, the vibration cycle becomes high, which increases the inertia, which may cause the operation of the conversion means to become unstable, or the force applied to the mechanism increases, causing the device to become large. This may lead to the engine becoming inoperable or causing an increase in costs. Furthermore, the force applied to the paper sheets increases, causing the paper sheets to bend and pile up.
It has the disadvantage that it cannot be considered a desirable means of integration for high-speed applications because it may break.

On the other hand, there is a method using an impeller as an accumulation means to compensate for such drawbacks. In this method, an impeller is installed that has a plurality of elongated blades in the circumferential direction that extend in the counter-rotational direction with the base end on the rotation center line side, and paper sheets are placed in the elongated space that exists between the blades of this impeller. This is a method in which the materials are sent in and accumulated. According to this method, if the total number of paper sheets being fed (taken out) to the transport means is N sheets/min, if the paper sheets are observed at any point on the transport path, the paper sheets being transported can be detected. The time t from when the leading edge of a sheet passes through until the leading edge of the next sheet arrives is t = 60/N Cse e ]. Now, if the long and narrow space of the impeller is defined as m stripes, the angle α from space to space is α=360/m ('). Therefore, in order to sequentially put the conveyed paper sheets into each space of the impeller, it is necessary to place the paper sheets outside one space (36o/rn[0
)) should be rotating at 60/N' [sec]. That is, since it takes 60/N [aec:] to rotate l/m, the rotation speed n of the impeller is -. Therefore, the rotational speed n of the impeller is equal to the number of filter paper sheets fed per unit time divided by the number of spaces, t, resulting in a very slow rotation. For example, even in the case of high-speed conveyance of 1800 sheets per minute, if the number of spaces is 18, the rotation speed of the impeller will be n = 100 [rpm], and stacking will be possible without any problem.

In this way, the impeller system has many advantages over other integrated systems. Therefore, conventionally, a paper sheet collection device has been proposed which combines the above-mentioned impeller accumulating means and a sorting means for sorting paper sheets into a fixed number of sheets without interrupting the conveyance of the sheets.

This recovery device, as typified by the device described in Japanese Patent Application No. 56-26369, has a rotation center line that almost coincides with the rotation center line of the impeller. A semi-9r is provided, which consists of an arm extending along the side surface to a position beyond the periphery of the impeller, and a receiving part provided at the tip of this arm, and by rotating the separator upward, the impeller can be rotated. Paper sheets inserted into the space of the car are pulled out from the space by applying them to the arm section, and the pulled paper sheets are temporarily held by the stop section, and during that time, The paper sheets that have been previously extracted by the fixed stopper and are stacked on the stacking means are sent out, and then the paper sheets that are being stacked on the separator are delivered to the stacking means.

[Problems with background technology]

However, the conventional paper sheet collection device that combines the impeller accumulating means and the sorting means as described above has the following problems. In order to temporarily receive the subsequent sheets, the arm of the seccretor is used as a stopper as described above, and the specified number of sheets plus the first sheet are pulled out from the space of the impeller. is held in the receiving part, so the arm part is necessarily positioned within the width of the paper sheet inserted into the space of the impeller (the width along the rotation center line direction of the impeller). That means you are doing it. Therefore, when the separator is located in the section between the paper sheet feeding position to the impeller and the sorting start position (receiver starts to stop), the so-called depth of the space in the impeller increases due to the presence of the arms. It becomes a substantially shallow state. Therefore, when the seccretor is in the above section, the paper sheet that is sent into the impeller will have only the leading end in the space and the rear end projecting out of the space. There is a problem in that the entrance of the space into which the next paper sheet is to be inserted is blocked, and the next paper sheet cannot enter the space and collides with the paper sheet blocking the entrance, resulting in a jam. Therefore, in order to solve this problem, it is necessary to lengthen the interval between feeding the paper sheets to the impeller, which often results in the problem that the processing speed of the paper sheets cannot be increased.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and its purpose is to reduce the amount of paper that is fed one by one without impairing the high speed inherent to the impeller stacking system. An object of the present invention is to provide a paper sheet collection device that can collect leaves by sorting them into a fixed number of stacked layers.

[Summary of the invention]

The present invention provides an arm portion having a rotation center line substantially coinciding with the rotation center line of the impeller and extending from the rotation center line along the side surface of the impeller to a position beyond the peripheral edge of the impeller; The paper sheet is provided with a seven-wheel tray consisting of a receiving section provided at the tip of the impeller for receiving the paper sheet pulled out from the impeller, and the arm section is inserted into the space of the impeller. , that is, outside the width area of the paper sheets in the direction of the rotation center line, so that the paper sheets can be extracted from the impeller by a fixed stock knock over all the paper sheets. The present invention is also characterized in that the center plate is provided with a blocking portion that prevents paper sheets that have been pulled out of the impeller from entering onto the catch portion.

〔Effect of the invention〕

According to the paper sheet collecting device according to the present invention, since the arms of the nanano-9V-Yu are provided in the above-mentioned relationship, the paper sheets that are fed into the impeller or fed into the separator are attached to the arm portions of the separator. I can't touch it. Therefore, the paper sheets fed into the space of the impeller can always be fed quickly and completely into the space, so unlike the conventional device, the paper sheets are fed at a sufficient interval. There's no need. Furthermore, since the separator is provided with a blocking portion that performs the above-mentioned function, it is possible to reliably separate the separator. Therefore, it is possible to maximize the high-speed performance of the impeller system, and to obtain a product that can be separated into a certain number of stacked layers and collected.

4.5 Drive circuit 11 of motor 112 for driving c f
1 as a control signal.

Next, the operation of the paper sheet collection device configured as described above will be described in a class p'6 process with reference to FIGS. 9 to 16 as appropriate. In order to satisfy this condition, the time from when the leading edge of the paper sheet P conveyed by the conveyor belt mechanism 31 passes the position until the leading edge of the next sheet P reaches that position is 50 milliseconds. The running speed of the conveyor belt mechanism 31 and the feeding of paper sheets into the conveyor belt mechanism 31 are set so that. At this time, it is assumed that the time from when the rear end of the paper sheet P passes a certain position until the leading edge of the next paper sheet P reaches that position is 25 milliseconds. Furthermore, in order to satisfy the above conditions, in this embodiment, the rotation speeds of the impellers 7a and 7b are set as follows. That is, in this example, since the elongated space 11 is formed in 12 strips in the circumferential direction, the rotation angle α of each strip is 30'. Therefore, since it is sufficient to rotate this angle for a total of 50 milliseconds, the impeller 7ar 7b
The rotation speed N is set to N=100 (rpm). In other words, the illustrated driving sources are impellers 7a and 7b.
iloo (rpm) The belt 34, 36f is rotated in the direction shown by the arrow 120 in FIG.

However, now, exactly the first crater 21a, 21J
Assume that it is set at the position shown in FIG. 1, beyond the delivery port of the conveyor belt mechanism 31, and directly beside the separator detector 52b. In the case of Party B, separates 121
The distance S between the arms 22 of the a r 21b is the paper sheet P
The width W of the bearing teeth 24 may be set to be larger than the width W of the impellers 7a and 7b.

Furthermore, the side 26 of the portion 23 supporting the teeth 24 of the receiver is located slightly inside the outer edge of the tip of the blade 10, but in the position where the separator 21a+:jlb is waiting, the conveyor belt mechanism The impeller 7a is sent out from the delivery port 31.

The paper sheet P that has entered the space 1 of 7b has completely entered the space 11. Therefore, the leading end body of the paper sheet P enters into the space 1 in exactly the same state as if the paper sheet P and the seven and nine plates 21g and 21b were not present. The inserted paper sheets P rotate as the impellers 7a and 7b rotate. Then, when the support plate 2a rotates to the position where it is exactly reversed, the support plate 2a exists between the impellers 7a and 7b.

The tip abuts against the left end surface of 2b in FIG. 1, thereby stopping the rotation. The left end surface functions fully as a stopper. Impeller 7a.

7b continues to rotate completely, so the paper sheet P that is stationary within the space 11 is gradually pulled out from the rear end side to the outside of the space 11, and finally the entire sheet is pulled out and is in an almost horizontal state. Deposition device 4
It naturally falls onto the belts 45a+45b and 45c of No.1. Therefore, the belts 45a, 45b, 45c''
j; At C, an accumulated layer of paper sheets P whose thickness gradually increases is formed.

By the way, in this state, the secretor 21a,
Since the arm portion 22 of the secrator detector 52b is located on the side of the secrator detector 52b, the optical path of the photocazola constituting the secrator detector 52bf is blocked by the bar 51.

Therefore, the output of the seccretor detector 52b is held at a low level, while the output El of the seccretor detector 52g is held at the no level since there is nothing blocking the optical path. Further, since the noyalus generator 56 is provided with the small hole 59 in the above-mentioned relationship, the noyalus generator 56 sends out a gust-like output F at intervals of 50 milliseconds, and furthermore, the passage detector 66 also sends out a gorus-like output F at approximately 50 millisecond intervals. It sends out a pulse-like output.

Therefore, while the paper sheets P are being accumulated one after another as described above, at the time t1 shown in FIG. Then, if the rear end of the 100th + 1st paper sheet P passes on the optical axis connecting the light emitting element 64 and the light receiving element 65, at the above time t1, the number detector 63
An output J is sent out.

This output J is supplied to the delay circuit 89 of the control device 81 shown in FIG.
, one shot)-multiple 90 to one input end of the AND/DART 91 .

Here, the delay time T1 of the delay circuit 89 is set as follows. That is, in FIG. 11, if the paper sheet P1 that has entered the space 11a between the blades 10a and 10b is exactly the 101st sheet, then the paper sheet P1 is detected by the number detector 63. The blade 10 is located in front of the paper sheet P1 from the time when the blade 10 crosses the optical axis, that is, tl.
It is set to the time required for the tip Q of b to reach just beside the center line R of the arm portion 22 of the cenocerator 21a, 21b in the axial direction. Then, when the tip Q of the V-blade 10h rotates to a position that coincides with the center line R in the axial direction,
As can be seen from the positional relationship of the small holes 59 shown in FIG. 7, an output F similar to a pulse is sent out from the pulse generator 56, and at the time t! , the AND gate 91 is opened and the one-shot multi 96 is driven. On the other hand, at this time t2, the output E
Since l is at a high level, AND/DART 88 is eventually opened at time t2, and transistors 99 and 102 are controlled to be on. Therefore, the output pulse of the pulse generator 98 is given as a control signal to the drive circuit 103 via the transistors 99 and 102, which causes the pulse motor 14 to rotate and cause the separators 21a and 21b to react as shown in FIG. Rotate clockwise. here,
The frequency generator 9B is configured to send out output pulses with a control period that allows the output rotation speed of the pulse motor 14 to match the rotation speed of the impellers 7a and 7b.

Therefore, the senomother 21a.

21b is the impeller 7a that has been positioned right next to the tip Q of the blade 10b on the center line Rt of the arm s22, as shown in FIG. 12, from time t2.

Impeller 7a rotates in the same direction as #7b at the same angular velocity as #7b.

Therefore, as described above, the senogulator 21a.

21b rotates to the position shown in FIG. 13 at time t3, that is, when it rotates to the side of the separator detector 52a, all the optical path bars 51 of the photocoupler constituting the separator detector 52ak are cut off. Therefore, the output E1 of the separator detector 52a becomes low level. As a result, AND gate 88 closes and transistors 99.10
2 switched to off state/? The drive of the loose motor 14 is stopped. Therefore, the separators 21a and 21b also stop at the position shown in FIG. 13. In the process leading to this stop, the space I between the blades 10a and 10b
The leading end of the 101st paper sheet P1 inserted into Ia stops rotating completely when it hits the left end surfaces of the support plates 2a and 2b, and as a result, its trailing end gradually moves out of the space 11a. And finally, it comes out completely. In this case, the separator 21a.

21b, until it stops at the position shown in FIG.
Since the 101st sheet P1 pulled out from the space 11a does not fall downward, it is placed right next to the paper tray 21a, 21b and is rotated.
4 can be easily accepted. Moreover, the separator 21a
.

Since the side 26 of the portion 23 of 21b is located on the inner side of the outer edge of the tip of the blade, even if the 100th sheet tries to enter the so-called upper space of the receiving tooth 24, it will not be able to reach the back surface of the portion 23. Intrusion is prevented by That is part 2
3 functions as a blocking member that prevents the paper sheet previously pulled out from the space 1 from entering onto the receiving tooth 24. Therefore, the 100th sheet of paper and the 101st sheet of paper P
1 is completely separated by the receiving tooth 24, and the 101st and subsequent sheets are accumulated on the receiving tooth 24 one after another.

When the rotation of the mono 4-lator 21 a p 2 l b is stopped and the output E of the separator detector 52 a is switched to a low level, the output E1 of the inverter 94, which has inverted the output E1, becomes a low level. Switch to Irepel. This output E1 is applied to a delay circuit 108 and a differentiation circuit 109 which differentiates the rising edge De of the output of this circuit. The output of the differentiating circuit 109 is then given as a control signal to the drive circuit 111 of the motor 112 via a one-shot aluminum alloy. For this reason, the motor 112 starts rotating from time t3, and the motor 112 starts rotating for the time set by the one-shot multi 110 (bell) 45 a t45b, 45c? , in the direction shown by the arrow 121 in FIG. 14 to move the accumulated layer of paper sheets P accumulated on the belt to the bottom and outside of the impellers 7a and 7b. The delay time T2 of the delay circuit 108 is set to the time required for the 100th sheet P to completely fall. Even during this period, paper sheets P are accumulated one after another on the receiving tooth 24.

As above, belt 45a + 45b, 4
At time t4 when the accumulated layer on 5c is transferred from below the impeller 7a r 7b, the output M of the deposition detector 69 switches to high level. This output M is introduced into an AND gate 93 via a delay circuit 92. The delay circuit 92
The delay time t3 is set to be approximately the same as the period from time t4 when the output M switches to high level until the belts 45a, 45b+45c stop running. At the time when the output of the delay circuit 92 is switched to high level in this way, the output E1 of the inverter 94 is at high level.

In the above state, when the pulse-like output K is sent out from the pass-through quadrupler 66 at time t5, the AND gate 93 opens and the one-shot multi 97 is driven. At this point, the output E2 of the separator detection 5s;zb is at a high level, so that the AND dart 95 is eventually opened at the time t5, and the transistors 100 and 101 are turned on. As a result, the output pulses of the Noyals generator 98 are introduced into the counter 104 through transistors 100 and 101. The output of the counter 104 is converted into a voltage level by a D/A converter 105, and this voltage level signal is introduced into a V/f converter 106 where it is converted into a pulse signal with a period inversely proportional to the voltage level. and,
The above signal is the drive circuit 10 of the Norse motor 14.
3 as a control signal, so that the pulse motor 14 starts rotating again from time t5, and as a result, the mono-fourators 21a, 21b rotate in the same direction as the rotation direction of the impellers 7a+7b, as shown in FIG. Along with this, the paper sheets P that had been accumulated on the receiving teeth 24 of the separators 21a and 21b are received on the belt 451k + 45b + 45c as shown in FIG. passed on.

Here, the position where the optical axis of the photocoupler constituting the above-mentioned counter 104, the D/A conversion, and the above-mentioned passage detector 66 intersects with the conveyor belt mechanism 3 is designated as X, and the cenogrator 27a, If Y is the position where the locus 2 of the receiving tooth 23 intersects with the conveyor belt mechanism 3 when 21b is rotated, then the distance t between X and Y is constant. Also, since the running speed of the conveyor belt mechanism 3 is kept constant, from the time when the rear end of a certain paper sheet P passes the position The time Tt at the point of passing through is also always constant. Therefore, in this embodiment, as shown in the right half of FIG.
Then, the rotation of the smoke 14 is started and the speed is gradually increased while the torque is constant, and immediately after the time Tt has elapsed from the above-mentioned time t5, the rotation of the smoke 14 is started, and immediately after the time Tt has elapsed from the above-mentioned time t5, the rotation of the smoke 14 is started.
The above-mentioned control pulse generation system is set so that the receiving tooth 24 passes directly beside the position Y at a speed several times the traveling speed of the conveyor belt mechanism 3. Therefore, in this example, the receiving teeth 24 of the separators 21a and 21b can contact the paper sheet P running on the conveyor belt mechanism 31 without particularly increasing the load torque of the arm smoke 14. Instead, the teeth 24 of the receiver pass right next to position Y through the gaps that exist between the paper sheets. In addition, the left half of Figure 10 is Se Yareta 2Ja
, 21b from the state shown in FIG. 11 to the state shown in FIG. 13.

Thus, as described above, the separator 21a.

21b rotates and its arm portion 22 reaches right next to the cenogrator detector 52b as shown in FIG. At t6, the output E2 of the mono 9-lator detection 'f452b is switched to low level. As a result, the AND dart 95 is closed, the transistors 100 and 10 are turned off, and the counter 104 is reset by the output of the differentiating circuit 107. Therefore, at this time t6, the rotation of the pulse motor 14 is stopped, and the separator 2]a.

2Jb stops at the position shown in FIG. 16, i.e., at the position υ shown in FIG. 11, and enters a so-called standby state. Thereafter, the above-described operation is repeated starting from the point in time when the output J of the sheet number detector 63 is introduced. Therefore, the paper sheets P that are continuously fed one by one are reliably divided into stacked layers of 100 sheets each, and these divided stacked layers are sent one after another to a device located at a later stage, and then It functions well as a collection device equipped with a sorting means.

In this case, the separator 21a.

2Jb arm 22 is placed in a position where it does not touch the paper sheet P at all, the tab υ is inserted into the space 11 of the impeller 7a+7b.
Since the arm portion 22 is positioned outward from the side end surface of the paper sheet P, the arm portion 22 prevents the paper sheet P from entering the space 1 no matter where the separators 21m and 21b are located. There's nothing to get in the way. Therefore, the feeding density of the paper sheets P is not limited by the presence of the senorators 21a and 21b. In addition, since the separators 21h and 21b are provided with a blocking portion that prevents the paper sheet that has been pulled out of the space J1 from entering the receiving tooth 24, it is possible to accurately separate the paper sheets. The above-mentioned effects can be obtained.

Note that the present invention is not limited to the embodiments described above. That is, in the embodiment described above, separator 2 J
A + 2-1 b is stopped at only two places, the timing position shown in Fig. 11 and the so-called receiving position shown in Fig. 13, but the receiving position does not stop from the stopping position to the standby position. From this position, the receiving teeth 24 of the separators 22a and 21b move the sheet at a speed several times the running speed of the conveyor belt mechanism 3. A control system may be configured to pass through the gap between the class P.

In this case, compared to the case of the embodiment, the motor J4
Although the load torque increases, it becomes easier to adjust the timing for passage. Further, in this case, in relation to the timing of division, the impeller may be rotated at the same speed as the impeller near the standby position, and rotated toward the receiving position as in the embodiment. moreover,
In the embodiment described above, the separators 2Ja, 21b are 36
Although the rotation angle is 0 degrees, the rotation angle may be 180 degrees or less, and control may be performed in combination with an axial movement control system. That is, in this case, only one separator or two separators whose movement is controlled axially symmetrically with respect to each other are provided, and the ends of the arm portions of this separator function as blocking portions as in the above embodiment. and a receiving tooth extending in a hawk shape. and,! As shown in Figure 12, after feeding out the accumulated layer of paper sheets that have been accumulated so far, the receiver uses the gap between the teeth, with all the paper sheets after the specified number + 1 sheet being stopped. The sheets deposited on the receiving pawl are transferred to the auxiliary stacking device, and then the separator is moved in the axial direction so that the receiving pawl is separated from the stacked layer. Next, the paper and leaves on the auxiliary stacking device are transferred to the main stacking device, and the separator is rotated by a predetermined angle in the direction opposite to the rotating direction of the impeller. direction so that the receiving teeth face the outer peripheral surface of the impeller and stand by. Then, it is rotated from this standby position to the receiving position using the same means as in the embodiment, and thereafter the series of operations described above is repeated. Even with this configuration, the same effects as in the embodiment described above can be obtained. Further, a plurality of pairs of separators shown in the embodiment may be provided in the circumferential direction. Moreover, although the blades of the impeller are formed in the shape of an indelute curve on the shinjiryu side, the blades are not necessarily limited to this shape, and may be formed into other known shapes. In a further developed embodiment, the portions 23 of the separators 2Ja and 2Jb are inclined in the radial direction, and these inclined portions constitute blocking portions.1. However, as shown in FIG. 17, a blocking plate 200 may be added, and the upper edge 20 of this plate 200 in the figure may be located inside the outer edge of the tip of the blade. Furthermore, as shown in FIG. 18 and FIG.
2.203 may be provided.
