From S9 to S9. For example, if the read destination code is COD963,
Since the digit of 1s is 3, the paper sheet 2 is put into the divided area S3 in the second stacking unit 11A corresponding to 3.

When all the paper sheets 2 are similarly put into the divided areas S0 to S9 according to the 1's place of the destination code 15, the papers having only the 1's are arranged in the divided areas S0 to S9. Leaf 2 is accumulated. Where the destination code is
CODXX0 means that all 1's are 0, but 10's and
The place of 100 indicates that the paper sheets 2 in which any number from 0 to 9 are irregular are accumulated.

Next, all the paper sheets 2 are put into the first collecting means 1
All of the first and second stacking means 11A are moved into the supply means 1 so that the order is the same as the order in which they are stacked in the divided areas S0 to S9. That is, first, the divided area S
The sheet 2 having the destination code 15 of CODXX0 accumulated in 0 is moved from the first accumulating means 11 into the supplying means 1. Next, the paper sheets 2 with the destination code CODXX1 accumulated in the divided area S1 are moved from the second accumulating means 11A into the supplying means 1 so as to overlap the paper sheets 2 with CODXX0. By repeating the above procedure, all the paper sheets 2 from the divided area S0 to the divided area S9 are sequentially moved into the supply means 1.

FIG. 9 shows a state after the paper sheet 2 is moved. In this state, the paper sheet 2 in the supply means 1 is pushed by the push plate 3 to move it to the separating means 4 side, and again only the uppermost paper sheet is separated and conveyed to the left in order. The transported paper sheets 2 are
This time, it is sorted by the second digit from the bottom of the destination code, that is, the digit of ten.

In FIG. 10, the division by the second digit, that is, the tens digit is shown. Contrary to the case of the unit of 1 shown in FIG. 8, in the unit of 10's,
9 to 0 are made to correspond to the divided areas S0 to S9 in the first stacking means 11 and the second stacking means 11A in order. Figure 9

Are divided into the divided areas. After the sorting of the paper sheets 2 in which only the 1s digit is 9 is completed, similarly, the paper sheets 2 whose 1s digit is from 8 to 0 are sequentially in the second digit of the destination code 15, that is, It is divided and put into one of the divided areas S0 to S9 corresponding to the tens digit.

As a result, inside the divided area S0, the 100s are not aligned on the lower end side, but the paper sheets 2 having the last two digits of 99 are accumulated, and the 100s position is not aligned on the upper side. The paper sheets 2 whose last two digits are 98 are accumulated, and the paper sheets 2 whose last two digits are 97, although the positions of 100 are not aligned, are accumulated on the upper side thereof. Repeat this and 100 at the top

Inside the segmented area S1, the paper sheets 2 whose lower two digits are 89 but whose lower two digits are 89 are not gathered on the lower end side, and the lower two digits are 8 on the upper side, although 100 digits are not aligned.
The paper sheets 2 of 8 are accumulated, and further, the paper sheets 2 of which the second two digits are 87 are not accumulated in the upper 100, but the 100 digits are not aligned. By repeating this, the paper sheets 2 whose uppermost two digits are 80 but not in the uppermost 100 are accumulated. Similarly, inside the divided area S9, the paper sheets 2 having the lower two digits of 09 are not aligned on the lower end side, but the lower two digits are 09, and the 100 digits are not aligned on the upper side, but the lower two digits are. The paper sheets 2 of 08 are accumulated, and the paper sheets 2 of which the second two digits are 07 are not accumulated on the upper side of the paper sheets 2 but are accumulated. By repeating this, the paper sheets 2 whose uppermost two digits are 00 but not aligned to the uppermost 100 are accumulated.

When the sheets 2 thus stacked on the first stacking means 11 and the second stacking means 11A are sequentially moved to the feeding means 1, as shown in FIG. 11, the last two digits are 00 at the upper end.
The paper sheets 2 of No. 2 are in a state in which the paper sheets 2 having the last two digits of 99 are arranged in order at the lower end.

12 to 13 show division by the third digit, that is, by the hundreds place. In the division by 100's place, contrary to the case shown in FIG. 10, 0 to 9 are made to correspond in order to the divided areas S0 to S9 in the first stacking means 11 and the second stacking means 11A. As shown in FIG. 11, first, the paper sheets 2 arranged in the last two digits 00 are supplied to the separating means 4, and the paper sheets 2 having the destination code 15 read by the first destination code reading means 9 are: Destination code 1
It is divided and put into any of the divided areas from S0 to S9 corresponding to the digit of 100 of 5. Similarly, the paper sheet 2 having the tens place of 8 to 0 is sequentially sorted and put into any one of the sorting regions of S0 to S9 corresponding to the number of the 100s place of the decoded destination code 19.

As a result, as shown in FIG. 12, inside the divided area S0, the paper sheets 2 of COD000 are accumulated at the lower end, the paper sheets 2 of COD001 are accumulated on the upper side thereof, and further on the upper side thereof. Paper sheets 2 of COD002 are accumulated. By repeating this, the paper sheets 2 of COD099 are accumulated on the uppermost side. Inside the divided area S1, the sheets 2 of the COD 100 are accumulated at the lower end thereof, and the CO 2 is above the COD 100.
Paper sheets 2 of D101 are accumulated, and CO is further above it.
The paper sheets 2 of D102 are accumulated. By repeating this, the paper sheets 2 of COD199 are accumulated on the uppermost side. Similarly, inside the divided area S9, the paper sheets 2 of the COD 900 are accumulated at the lower end and the paper sheets 2 of the COD 901 are arranged at the upper side thereof.
Is accumulated, and the paper sheets 2 of COD902 are further on the upper side.
Are accumulated. Repeat this to get COD9

After the above operation, the first accumulating means 11 is again provided.
When the paper sheets 2 accumulated in the second accumulating means 11A are sequentially moved to the supplying means 1, as shown in FIG. 13, the supplying means 1 has the COD000 paper sheets 2 at the lower end and C at the upper end.
The paper sheets 2 of OD999 are accumulated, and all the paper sheets 2 are arranged in the order of the destination code 15 displayed on the paper sheets 2.

In this embodiment, as a result of rearranging the paper sheets 2, as a result, the paper sheets having the destination code COD000 come to the lower end and the paper sheets having the destination code COD999 are arranged to the upper end, but FIG.
If the arrangement of the numbers corresponding to the divided areas S0 to S9 in FIGS.

Further, in this embodiment, COD000 to CO
An example has been shown in which 1000 sort operations up to D999 are performed by repeating division into 10 divided areas three times, but this operation is not limited to this, and the number of divided areas is U and repeated. If the number of times is n, it is possible to perform rearrangement according to the nth power of U.

Next, an example of means for moving the paper sheets 2 from the first stacking means 11 to the feeding means 1 without manpower as shown in FIGS. 9, 11, and 13 will be described.

In this embodiment, the side plate 12A and the side plate 12 are
B is supported so as to be able to move forward and backward with respect to the bottom surface of the supply means 1, and when the side plates 12A and 12B are moved to the back side, that is, in the direction of retracting to the bottom surface, the first collecting means 11 and the second collecting means 11 The boundary between the stacking means 11A and the supplying means 1 disappears, and the paper sheets 2 stacked on the first stacking means 11 and the second stacking means 11A are transferred to the first stacking means 11 and the second stacking means 11 by the transfer means 30a to 30j. The second stacking means 11A can be moved into the supply means 1 in the same order as they were stacked.

Next, an example of means for moving the paper sheets 2 from the first stacking means 11 and the second stacking means 11A into the supply means 1 will be described below.

FIG. 14 is a perspective view showing an example of the structure of the boundary member moving means for moving the side plates 12A and 12B. In FIG. 14, the side plate 12A is the first stacking means 11
The structure is divided for each divided area. 20 is a side plate 12
One end of a link 23 is pivotally attached by a pin 20 to the side on the bottom surface side of A, and the other end of the link 23 is rotatably attached to a peripheral end 24 of a disk-shaped cam 21 that rotates around a rotation center 22. It is supported.

Here, FIG. 14A shows a state in which the cam 21 is rotated 180 ° around the rotation center 22. Cam 21
When the pin rotates about the center of rotation 22, one end of the link 23 is pivotally supported by the tip 24 of the cam 21.
0 is moved in the direction of the rotation center 22 of the cam 21 (arrow B direction), and the entire side plate 12A is moved in the direction of the rotation center 22 of the cam 21. Here, the moving distance of the side plate 12 is determined by the cam 2
The rotation diameter of 1 is doubled, that is, the distance between the rotation center 22 and the tip 24, and the rotation diameter of the cam 21 can be determined according to the required amount of movement of the side plate 12A.

The rotation diameter of the cam 21 is the height h of the side plate 12A.
Therefore, when the cam 21 is rotated, the side plate 12A is retracted from the bottom surface of the supply means 1, and the partition between the first stacking means 11 and the supply means 1 is lost. Thereafter, the transfer means 30 provided for each divided area is driven in the direction of the arrow E by a driving means (not shown) such as an electric motor, and the paper sheets 2 accumulated in the divided area are removed from the first accumulating means 11. It is moved to the supply means 1.

Here, an example in which a rotating cam is used to move the side plate 12 has been described, but the invention is not limited to such a configuration, and for example, a linear moving means using air pressure or hydraulic pressure is used. Is also good.

Alternatively, as shown in FIG. 15, the side plate 12A
Have a positional relationship in which they overlap each other in the shape of a roof tile, and the side plate 12A is moved in the direction of arrow F to eliminate the partition between the first stacking means 11 and the supplying means 1. May be.

The process of rearranging the paper sheets 2 in the order of the destination codes 15 displayed on the paper sheets 2 has been described above, but the description so far has been for the paper sheets 2 to be rearranged. The supply means 1 or the first collecting means 1
This is an example in which the capacities of the first and second accumulating means 11A are not exceeded and the capacities of the respective divided areas S0 to S9 are not exceeded.

Next, a means for rearranging the sheets 2 when the amount of the sheets 2 exceeds the capacity of the supply means 1 will be described.

FIG. 16 is a block diagram showing the construction of one embodiment of the paper sheet sorting apparatus of the present invention. In the present embodiment, as an example, the first stacking unit 11 and the second stacking unit 1

Third memory unit 65 for storing a correspondence between each segmented region in the second stacking means 11A is provided.

Further, a separating means controlling means 67 capable of controlling the separating means 4, a supplying means controlling means 68 capable of controlling the push plate 3 of the supplying means 1, a means for moving the side plates 12A and 12B and transfer.

The control means 66 includes the thickness detection means 18, the first destination code reading means 9, the first storage section 62, the second storage section 64, the third storage section 65, the standing means 63, and the first storage section 63. First distribution control means 60, second distribution control means 6

The flow charts shown in FIGS. 17 to 22 and Tables 1 to 4 are flow charts showing the operation of the paper sheet sorting apparatus according to this embodiment.

The operation of this embodiment will be described below with reference to FIGS. When the apparatus is started, the control means first obtains, from the sorting information input means 71, delivery sorting information indicating the correspondence between the destination code 15 assigned to the paper sheet 2 to be processed and the delivery route (step 99). Delivery classification information is
For example, an address and a destination code corresponding to it.

Next, the control means obtains the thicknesses of all the paper sheets 2 and the destination code 15 (step 100). Details of this operation will be described with reference to FIG.

FIG. 19 shows the thickness of the paper sheet 2 and the destination code 1.
5 is a flowchart showing a procedure for acquiring 5.

First, when the paper sheet 2 is supplied to the supply means 1 (procedure 201), a signal is sent from the control means 66 to the supply means control means 68 and the separation means control means 67, and the supply means 1 pushes the push plate. 3 is urged in the direction of the separating means 4 to move the paper sheets 2 in the direction of the separating means 4, and in the separating means 4, the paper sheets 2 are separated one by one from the upper end and sent to the conveying means 7 ( Procedure 202). The thickness of the paper sheet 2 is measured by the thickness detecting means 18 while being conveyed by the conveying means 7 (procedure 20).
3) The measured thickness is transmitted to the first storage unit 62 via the control means 66 and stored (procedure 204). The paper sheet 2 is further read by the destination code 15 given in advance by the first destination code reading means 9 (procedure 20).
5) The read destination code is transmitted to and stored in the first storage unit 62 via the control means 66 (procedure 20).
6). In this way, the destination code 15 and the thickness of each sheet 2 are stored in the first storage unit 62 in association with each other.

Table 1 shows an example of the contents stored in the first storage unit 62. Here, the sheet passing number is a temporary number given to the paper sheets 2 in the order in which they are passed. In this way, the destination code 15 for each sheet 2 is stored in the first storage unit 62.
And the thickness are stored in association with each other.

[0082]

[Table 1]

The control means 66 cumulatively integrates the thicknesses of the sheets 2 that have been passed every time the sheets 2 are passed one by one (procedure 207), and passes the sheets. It is determined whether the cumulative total of the thicknesses of 2 is shorter or longer than the length (thickness that can be accommodated) of the first stacking unit 11 and the second stacking unit 11A (step 208). If the cumulative thickness is shorter than the total accommodable thickness of the first stacking means 11 and the second stacking means 11A,
It can be determined that the first stacking unit 11 and the second stacking unit 11A can be stacked. In that case, it is accumulated in the first accumulation means 11 or the second accumulation means 11A (procedure 20).
9). If not, the second distribution control unit 61 is controlled to operate the third distribution means 17 (procedure 21
0), the overflowed paper sheets 2 are accumulated in the third accumulation means 16 (procedure 211). The destination code and the thickness information are acquired as described above.

When the total amount of the paper sheets 2 exceeds the amount which can be supplied to the supply means 1 at a time (the cumulative thickness is equal to the accommodating thickness of the first stacking means 11 and the second stacking means 11A). If it is thicker than the total), it becomes necessary to divide the entire paper sheet 2 and process it. In this embodiment, the paper sheet 2 is divided into several areas by the amount that can be processed at one time, and each area is called a processing area (procedure 101).

An embodiment for setting the processing area will be described with reference to FIG. The control means 66 reads out the destination code 15 and the thickness of the paper sheet 2 from the first storage section 62 (procedure 301), and the ordering means 63 causes the destination code 15 to be read.
Are sorted in the order of delivery (procedure 302) and then stored in the second storage unit 64 (procedure 303). Table 2 shows an example of the contents of the second storage unit 64 at this time. As illustrated, the destination codes 15 sorted in the order of delivery are the first column 320.
, The thickness corresponding to each is stored in the second column 321.

[0086]

[Table 2]

Next, the control means 66 adds all the thicknesses of the paper sheets 2 in order from the beginning of the destination code 15 stored in the second storage section 64, and obtains the total thickness Tall of the paper sheets 2 as Tall. Calculate (procedure 304).

Next, Tall is compared with the thickness R that can be supplied to the supply means 1 at one time (procedure 305). Tall ≦ R
If so, the whole process can be performed at one time, and therefore the process proceeds to the process 102 via the process 311, but if not so, the whole process needs to be divided into some processing regions. The thickness R mentioned here does not only mean the thickness that the supply means 1 can accommodate at one time, but also the total thickness that the first and second accumulating means can accommodate at one time.

When Tall> R, the control means 66 (note that
In the following description, arithmetic processing is executed by the control unit 66 unless otherwise specified. ), First, the total thickness of the paper sheets 2 that can be supplied to the supply means 1 is R, Tall / R is calculated, and the integer value obtained by rounding up the decimal part of the result is Q (step 3).
06). Q is the number of divisions of the paper sheet 2, that is, the number of processing areas. That is, all the paper sheets 2 have the processing region thickness Tseg.
= Tall / Q and divided into Q processing areas (procedure 307). With this, Tseg ≦ R is satisfied, so that it is possible to supply the paper sheets 2 in each processing area to the supply means 1 at once. In this embodiment, the case where Q = 3 will be described.

The destination code is sequentially added from COD000 to the thickness of the paper sheet 2 (procedure 308), which is taken as Σt, and Σt
<Destination code range that falls within the range of Tseg is obtained. For example, the total thickness of paper sheets 2 from COD000 to COD299 is Tse.
If it is smaller than g and the total thickness from COD000 to COD300 is larger than the processing area thickness Tseg, then COD000 to COD
Up to 299 are set as one processing area (procedure 309). This is called SEG1 in the sense of the first processing area, added to each destination code 15 and stored in the second storage unit 64 (procedure 310). Similarly, after COD300, the total thickness is set for each processing region thickness Tseg, and the processing region is set (step 311). Table 2 shows an example of the contents of the second storage unit 64 when the processing area is set. That is, the thickness of each sheet 2 and the processing area numbers SEG1 to SEG3 are given in the order of the destination code 15 as shown in the third column 322 of Table 2, and the destination codes COD300 to COD649 are assigned to the second processing area SEG2. And COD650 to COD999 as the third processing area SE
G3. The total thickness Σt of the paper sheets 2 belonging to the respective processing areas is substantially equal to each other. As described above, the processing area is set.

Here, the sheets 2 belonging to the first to third processing areas SEG1 to SEG3 each have a quantity that can be supplied to the supply means 1 at a time, but some of the destination codes 15
If there are many paper sheets 2 corresponding to, or thick paper sheets 2
When a large number of paper sheets are concentrated, paper sheets 2
Overflows. In order to avoid such a situation, it is possible to prevent overflow by predicting in advance a segmented region in which the number of paper sheets 2 is large and overflowing, and assigning a plurality of continuous segmented regions to the corresponding segmented region ( Step 102).

Next, the procedure 102 for setting the divided areas will be described in detail with reference to FIG. FIG. 21 is a flow chart showing details of the procedure 102 for setting the segmented area. As described with reference to FIGS. 7 to 13, the delivery route assembling operation is performed.
Paper sheets 2 having the same number in each digit are accumulated in one divided area. Therefore, it is possible to predict the occurrence of overflow by obtaining the thickness of the paper sheets 2 accumulated in one divided area for each digit in advance.

The partitioning operation is performed from the first digit of the destination code 15 in the first processing area SEG1, and an example of this case will be described with reference to FIG. 21 and Tables 3 and 4.

[0094]

[Table 3]

[0095]

[Table 4]

First, the processing area is set. Here, since the processing area starts from the first processing area SEG1, it is assumed that K = 1 (step 401). Next, the digit number N of the destination code 15 is set. Here, since the process starts from the first digit, N =
1 (procedure 402). Next, the destination code 15 of the paper sheet 2 belonging to the first processing area SEG1, that is, COD000 to COD299, and the thickness of the paper sheet 2 corresponding to each of them are read from the second storage unit (step 403). . Destination code 1
Put together items with the same first digit of 5 (procedure 40
4). That is, as shown in Table 3, for example, in the a column, only the destination code 15 with the first digit of the destination code 15 being 0 and the thickness are summarized, and in the b column, the destination code having the first digit of the destination code 15 is 1. 15 and the thickness are summarized, and similarly, the first digit is repeated from 2 to 9.

Next, the destination code 1 having the same first digit
Sum the thicknesses of the paper sheets 2 collected in step 5 (step 40
4). For example, when x is an arbitrary number, the total thickness of the paper sheets 2 whose first digit is 0 is represented as ΣCODxx0, and the thickness of the paper sheets 2 that can be accommodated in one divided area is s. As an example, s is
It is assumed to be 120 mm. If ΣCODxx0 is, for example, 65 mm, ΣCODxx0 <s, and therefore these paper sheets 2 can be accommodated in one section area. If ΣCODxx1 is 152 mm, for example, ΣCODxx1> s, and therefore these paper sheets 2 cannot be accommodated in one section area (step 405). Therefore, for the paper sheet 2 whose first digit is 1, two continuous segmented areas are provided (procedure 406).

Similarly, the above steps are repeated until the first digit reaches 9. For example, for the paper sheet 2 having the first digit of the destination code of 1 and 5, two continuous segmented areas are assigned, and for the others. For each, one section area is assigned.

There are 12 divided areas, each of which is expressed as S0 to S11. For the first digit of the first processing area, 0 is assigned to the divided area S0 and 1 is given to the divided areas S1 and S2. assign. Similarly, if the first digit 9 is sequentially assigned to each segmented area, the first digit of the destination code is assigned to all the segmented areas S0 to S11 as shown in c of Table 4, so that the third digit It is stored in the storage unit 65 (step 407).

This completes the first digit of the destination code of the first processing area SEG1. It is determined whether N = third digit is completed (procedure 408). If not completed, N is N +.
With 1 = 2 (procedure 409), the divided areas of S0 to S11 are similarly assigned to the second digit of the destination code 15. However, as described with reference to FIGS. 7 to 13,
Since it is necessary to reverse the setting of the numerical value for the divided area every time the digit of the destination code 15 changes, the destination code 15
In the second digit of, the divided area S0 is 9 and the S11 is 0.
To be assigned. Table 4b is the first processing area
Regarding the second digit of the destination code 15 of SEG1, this is an example in which two continuous segment areas are assigned to the paper sheets 2 whose second digit is 3 and 7. Since only the paper sheets 2 from COD000 to COD299 belong to the first processing area SEG1, numerical values from 0 to 2 for the third digit are sequentially assigned to each divided area. Here, since it is necessary to reverse the setting of the numerical value from the second digit, 0 is assigned to the divided area S0 and 2 is assigned to S11.

When the third digit is completed (procedure 410),
It is determined whether or not the third processing area SEG3 is completed (procedure 411), and if not completed, K is set to K + 1 = SEG2 (procedure 412), the divided area of the second processing area SEG2 is set, and the third processing area SEG2 is set. Repeat for the processing area SEG3 of
As shown from d to i in Table 4, all the divided areas of all the processing areas are set for the numerical value of each digit of the destination code 15 (step 413). Here, when the overflow of the paper sheet 2 does not occur in all the divided areas, only the divided areas from S0 to S9 are used and the other divided areas are not used, as shown in e of Table 4. May be.

As described above, all the processing areas SE are stored in the third storage section 65 in correspondence with the numerical value of each digit of the destination code 15.
The settings of all the divided areas S0 to S11 of G1 to SEG3 are stored, and the setting of the divided areas (step 102) is completed.

The control means 66 then controls the first processing area SEG1.
In order to start the processing from, the processing area number K = SEG1 is set (procedure 103).

First, in order to perform the division corresponding to the first digit of the destination code 15 corresponding to the procedure described with reference to FIGS. 7 to 8, the number of digits N = 1 is set (step 104). The control means 66 then determines from the third storage unit 65 to the first processing area.
The setting (according to c in Table 4) of the first digit of SEG1 is acquired (procedure 105) and stored (procedure 106). The control means 66 sends an instruction to the first distribution control means 60 based on the stored setting of the divided areas, and the distribution selection means 13 and the first and second distribution means 13A, 13 are provided.
Each of the switching gates 35a to 35j forming B is made to correspond to the set sectional area (step 107).

Next, when the paper sheet 2 is supplied again to the supply means 1 (procedure 108), a signal is sent from the control means 66 to the supply means control means 68 and the separation means control means 67, and the supply means 1 is fed with the paper sheet. The class 2 is moved in the direction of the separating means 4, and the separating means 4 separates the sheets 2 one by one from the upper end and sends them to the conveying path 7 (step 109).

The destination code 15 of the paper sheet 2 is read by the destination code reading means 9 (procedure 11).
0). The read destination code 15 is stored in the second storage unit 64.
(Procedure 111), the first processing area SEG1
From this, it is determined which processing area of the third processing area SEG3 the paper sheet 2 belongs to (procedure 112). If the paper sheet 2 belongs to the second processing area SEG2 or the third processing area SEG3, the control means 66 causes the second sorting control means 6 to operate.
The instruction is sent to 1, the third sorting means 17 operates (procedure 113), and the paper sheets 2 are accumulated in the third accumulating means 16 (procedure 114).

If the paper sheets 2 belong to the first processing area SEG1, they are stacked on the first stacking means 11 or the second stacking means 11A (step 115). In accordance with the first digit of the destination code, the first distribution control means 60 issues a command to operate the corresponding switching gates 35a to 35j and the distribution selection means 13. For example, when the destination code is COD180, as a result of associating with the contents of the second storage unit 64, it is found that it belongs to the first processing area SEG1, and further, the contents of the third storage unit 65 As a result of the correspondence, since the first digit is 0, it is determined that the paper sheet 2 is to be stacked in the divided area S0. Therefore,
