<First Embodiment>
First, with reference to FIGS. 1 a and 1 b, stacking that may occur when stacking the sheets 4 using the stacking apparatus 1 that stacks the transported sheets 4 in the stacking box 5. The accumulation disorder of the paper sheets 4 in the box 5 and the JAM of the paper sheets 4 will be described.

  FIGS. 1 a and 1 b show a stacking means 2 that is a part of the paper sheet stacking apparatus 1 and a swinging conveyor means 6 on which a stacking box 5 for stacking paper sheets 4 is mounted.

  The stacking means 2 includes a chute 3 for feeding paper sheets 4 into a stacking box 5.

  The swing conveyor means 6 includes a swing conveyor 7 on which the stacking box 5 is mounted, and positions the stacking box 5 at a position where the paper sheets 4 are loaded.

  The paper sheets 4 thrown in by the stacking means 2 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 to be stacked in a flat stack.

  Here, for example, as shown in FIG. 1 a, the paper sheets in the stacking box 5 when the stacking means 2 of the paper sheet stacking apparatus 1 has just started to stack the paper sheets 4 in the stacking box 5. Consider a case where the accumulation amount of 4 is small. As shown in FIG. 1a, the position where the paper sheet 4 introduced by the chute 3 for guiding the paper sheet 4 to the stacking box 5 contacts the wall surface inside the stacking box 5 (hereinafter referred to as the contact position of the paper sheet 4). When the distance from the stacking box 5 to the bottom of the stacking box 5 is large, the loaded paper sheet 4 is rotated to the front after standing in contact with the wall surface of the stacking box 5 as shown in FIG. It becomes a state. This phenomenon often occurs in the case where the center of gravity of the paper sheet 4 is biased, the paper sheet 4 that is easily beaten by the wind pressure, the warped paper sheet 4, or the like. When this phenomenon occurs, the stacking state of the sheets 4 in the stacking box 5 is disturbed, for example, the sheets 4 newly put in the stacking box 5 cannot be stacked and stacked.

  Further, as shown in FIG. 1B, a case is considered in which the accumulation of paper sheets 4 by the paper sheet accumulation apparatus 1 proceeds and the accumulation amount in the accumulation box 5 increases. In this case, as shown in FIG. 1b, if the angle of the chute 3 remains constant, the paper sheets 4 accumulated in the accumulation box 5 and the loaded paper sheets 4 are brought into contact with each other. There is a case where the paper sheets 4 are not stacked in the stacking box 5 and the paper sheets 4 cause JAM.

  In this embodiment, the contact position of the inserted paper sheet 4 is adjusted to avoid the phenomenon that the input paper sheet 4 stands in the stacking box 5 as shown in FIG. Further, by changing the input angle of the paper sheet 4 and adjusting the input position of the paper sheet 4 according to the accumulation amount of the paper sheet 4 in the accumulation box 5, the paper sheet as shown in FIG. 4 is avoided and JAM of the paper sheet 4 as shown in FIG.

  FIG. 2 shows a functional block diagram of the paper sheet stacking apparatus 1 of the present embodiment.

  The paper sheet stacking apparatus 1 includes a stacking unit 2 and a detection unit 8.

  The stacking means 2 includes a chute 3 for feeding the paper sheets 4 conveyed from the detection means 8 into the stacking box 5, and the paper sheets 4 are stacked using the chute 3. The paper sheets 4 thrown into the stacking box 5 by the chute 3 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 and are stacked in a flat stack.

  The chute 3 guides the paper sheets 4 toward the stacking box 5 and puts the paper sheets 4 into the stacking box 5. In addition, the chute 3 can change the angle at which the paper sheets 4 are inserted in accordance with the amount of the paper sheets 4 in the stacking box 5. Note that the insertion angle of the paper sheets 4 into the stacking box 5 by the chute 3 is initially set so that the distance from the contact position of the paper sheets 4 to the bottom of the stacking box 5 is equal to or less than a predetermined distance as shown in FIG. Is set. Here, the predetermined distance is a distance (height) at which the phenomenon that the paper sheets 4 put into the stacking box 5 described with reference to FIG. The predetermined distance includes the distance between the chute 3 and the stacking box 5, the input speed of the paper sheet 4, the design value of the paper sheet stacking apparatus 1 such as the angle of the chute 3, and the type (size and thickness) of the paper sheet 4 to be handled. It is determined by information such as). For example, the user of the paper sheet stacking apparatus 1 sets and changes the predetermined distance based on the information.

  Further, the stacking unit 2 receives information such as the thickness of the paper sheet 4 transmitted from the detection unit 8. The stacking unit 2 calculates the total thickness of the paper sheets 4 stacked in the stacking box 5 based on the thickness information of the paper sheets 4 received from the detection unit 8. In addition, the stacking unit 2 uses the threshold value stored in advance in a storage unit (not shown) of the stacking unit 2 and information on the calculated total thickness of the sheet 4, and the sheets 4 in the stacking box 5. It is determined whether or not the accumulated amount has reached a predetermined amount.

  When the accumulation unit 2 determines that the accumulation amount of the paper sheets 4 has reached a predetermined amount, the accumulation unit 2 adjusts the angle of the chute 3 into which the paper sheets 4 are put, and the paper sheets 4 to the accumulation box 5 are adjusted. Adjust the loading position. At this time, the stacking means 2 is configured such that the distance from the contact position of the paper sheets 4 put in the stacking box 5 to the uppermost paper sheets 4 stacked in the stacking box 5 is equal to or less than the predetermined distance described above. Then, the loading position of the paper sheet 4 by the chute 3 is adjusted. For example, the stacking unit 2 adjusts the angle of the chute 3 based on the calculated information on the total thickness of the paper sheets 4 and the information on the height of the stacking box 5 and the like. In addition, the stacking unit 2 may store a loading position that is equal to or less than the predetermined distance previously determined by the user of the paper sheet stacking device 1 and adjust the angle of the chute 3 according to the stored loading position. . The stacking means 2 inputs and stacks the paper sheets 4 using the chute 3 after adjusting the loading position.

  If the stacking unit 2 determines that the stacking amount of the paper sheets 4 has not reached the predetermined amount, the stacking unit 2 continues to stack the paper sheets 4 without adjusting the angle of the chute 3.

  The detecting means 8 detects the thickness of the paper sheet 4 that has been input and transferred from an input means (not shown) that inputs the paper sheet 4. The detection unit 8 transmits the detected thickness information of the paper sheet 4 to the stacking unit 2. Further, the detection means 8 conveys the paper sheet 4 whose thickness is detected to the stacking means 2 through a conveyance path such as a conveyor.

  Further, the accumulation amount threshold used by the accumulation unit 2 for determination is set based on the distance (height) at which the paper sheets 4 accumulated in the accumulation box 5 do not come into contact with each other. It is assumed that the storage means 2 (not shown) stores the accumulation amount threshold value in advance. For example, the user of the paper sheet stacking apparatus 1 may use the predetermined distance, the input position of the paper sheet 4 (the distance from the contact position of the input paper sheet 4 to the bottom of the stacking box 5, A threshold is set based on information such as the distance from the contact position to the uppermost sheet 4 in the stacking box 5, and is stored in a storage unit (not shown) of the stacking unit 2.

  Thus, when the paper sheets 4 are stacked in the stacking box 5 by adjusting the angle of the chute 3, the stacking means 2 causes the input paper sheets 4 to rise forward in the stacking box 5. Can be prevented. Further, the stacking means 2 secures a distance from the contact position of the inserted paper sheet 4 to the uppermost paper sheet 4 stacked in the stacking box 5 even when a predetermined amount of the paper sheet 4 is stacked. In addition, since the paper sheets 4 are input, the stacked paper sheets 4 and the input paper sheets 4 can be stacked without causing contact or collision. Further, the stacking means 2 is configured such that, even when a predetermined amount of paper sheets 4 are stacked, the distance from the contact position of the input paper sheets 4 to the uppermost paper sheets 4 stacked in the stacking box 5 is Since the paper sheets 4 are loaded so as to be equal to or less than the predetermined distance described above, it is possible to prevent the above-described phenomenon of rising up.

  FIG. 4 is an operation flowchart of the paper sheet stacking apparatus 1 of the present embodiment.

  The detection means 8 detects the thickness of the paper sheet 4 that has been input and conveyed by an input means (not shown) (S401). The detection unit 8 transmits the detected thickness information of the paper sheet 4 to the stacking unit 2. For example, the detection unit 8 transmits the thickness information to the stacking unit 2 every time the thickness information of the paper sheet 4 is detected. The detection unit 8 conveys the paper sheet 4 whose thickness information is detected to the stacking unit 2.

  The stacking means 2 stacks the paper sheets 4 using the chute 3 that guides the paper sheets 4 conveyed from the detection means 8 toward the stacking box 5 (S402). The chute 3 guides the paper sheets 4 toward the stacking box 5 and puts the paper sheets 4 into the stacking box 5. At this time, the paper sheets 4 put into the stacking box 5 by the chute 3 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 and are stacked and stacked. Further, the paper by the chute 3 is set so that the distance from the contact position of the inserted paper sheet 4 to the bottom of the stacking box 5 is not more than a predetermined distance so that the paper sheet 4 does not rise in the stacking box 5. The insertion position of the leaf 4 is initially set. For this reason, the input paper sheet 4 does not stand up in front of the stacking box 5.

  The stacking unit 2 receives the thickness information of the paper sheets 4 transmitted from the detection unit 8 and stores it in a storage unit (not shown) of the stacking unit 2. Further, the stacking unit 2 accumulates the stored thickness information of the paper sheets 4, and calculates the total thickness of the paper sheets 4 stacked in the stacking box 5 (the stacking amount of the paper sheets 4) (S403). ).

  The stacking unit 2 determines whether or not the calculated total thickness of the paper sheets 4 has reached a predetermined threshold value stored in a storage unit (not shown) (S404).

  When the stacking means 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has not reached the predetermined threshold (NO in S404), the stacking means 2 Accumulation continues (return to S402).

  If the stacking means 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has reached a predetermined threshold (S404, YES), the stacking means 2 stacks the paper sheets 4 The angle of the chute 3 thrown into the box 5 is changed, and the loading position of the paper sheets 4 into the stacking box 5 is adjusted (S405). As in the previous case, the paper sheets 4 thrown into the stacking box 5 by the chute 3 whose feeding position has been adjusted come into contact with the wall surface inside the stacking box 5, and then fall toward the bottom of the stacking box 5 to stack. Is done. At this time, the distance from the contact position of the inserted paper sheet 4 to the uppermost paper sheet 4 stacked in the stacking box 5 is the predetermined distance so that the above-described front turning phenomenon does not occur. The insertion position of the chute 3 is adjusted so as to be as follows. For this reason, the input paper sheet 4 does not stand up in front of the stacking box 5. Furthermore, since the contact position of the input paper sheet 4 is a predetermined distance away from the uppermost paper sheet 4 accumulated in the accumulation box 5, the contact with the accumulated paper sheet 4 The input paper 4 does not cause JAM.

  After adjusting the input position of the paper sheets 4, the stacking means 2 continues to stack the paper sheets 4 (S406).

  Further, the storage means (not shown) of the stacking means 2 may store a threshold value for determining whether or not the stacking box 5 is full. The stacking means 2 compares the threshold for determining whether or not the sheet is full with the calculated total thickness of the paper sheet 4 and determines whether or not the stacking box 5 is full of the paper sheet 4. The full stacking box 5 is transported by, for example, transport means (not shown) such as a conveyor. Further, after transporting the full stacking box 5, the empty stacking box 5 is transported to the stacking position and the stacking operation described above is performed.

  Therefore, according to the present embodiment, when the paper sheets 4 are stacked in the predetermined stacking box 5, it is possible to prevent a phenomenon that the paper sheets 4 thrown into the stacking box 5 stand. Furthermore, since the JAM caused by the collision of the paper sheets 4 in the stacking box 5 can be avoided, the operating rate of the apparatus can be increased without stopping the paper sheet stacking apparatus 1.

  Further, since it is possible to prevent the paper sheets 4 accumulated in the collection box 5 from being disturbed, it is necessary to arrange the paper sheets 4 by a human hand in a subsequent process after the collection into the collection box 5. There is no.

<Second Embodiment>
The integration method according to the second embodiment for solving the phenomenon shown in FIGS. 1a and 1b will be described in detail.

  The paper sheet sorting apparatus 9 of this embodiment is demonstrated using FIG.5 and FIG.6.

  FIG. 5 shows a form of a paper sheet sorting device 9 that sorts paper sheets 4 such as mails, etc., employing the accumulation method of this embodiment. The paper sheet sorting device 9 is a device that sorts whether or not the collected paper sheets 4 are paper sheets 4 that can be processed by a machine (for example, a flat sorter). It is. The paper sheets 4 sorted by the paper sheet sorting device 9 are transported to an apparatus such as a flat sorter, for example, and sorted for each zip code. FIG. 6 shows the flow of processing of the paper sheet 4 by the paper sheet sorting apparatus 9 of this embodiment.

  The paper sheet sorting apparatus 9 according to the present embodiment includes a loading unit 10, a one-way separating unit 11, a direction changing unit 12, a detecting unit 8, a stacking unit 2, an atypical conveying unit 13, and an empty container conveyor. 14, a full container conveyor 15, a swing conveyor means 6, and a control means (not shown). Each means other than the control means (not shown) is connected by a conveyance path such as a conveyor, and the conveyance path conveys the paper sheet 4 and the like.

  The paper sheets 4 are input to the input means 10 constituted by a flat conveyor in a state where the direction and the overlapping manner are irregular (the paper sheets 4-1 in FIG. 6A). After that, the paper sheets 4 that are roughly leveled on the flat conveyor are dropped onto a conveyor inclined at a predetermined angle (for example, 45 degrees), and one sheet separating means is provided with the bottom edges of the paper sheets 4 aligned. 11 is conveyed.

  The one-sheet separating unit 11 sends out the paper sheets 4 conveyed from the input unit 10 one by one, and conveys the fed paper sheets 4 to the direction changing unit 12. At the time of passing through the single separating means 11, the paper sheet 4 has a predetermined angle (for example, the paper sheet 4 conveyed in the longitudinal direction and the paper sheet 4 conveyed in the short direction mixed). 45 degrees) is conveyed on an inclined conveyor. For example, as shown in FIGS. 6 (a) and 6 (b), the single-separation means 11 passes one sheet 4-2 conveyed in the longitudinal direction and one sheet 4-3 conveyed in the short direction. The separated paper sheets 4 are conveyed to the direction changing means 12 one by one.

  The direction changing means 12 measures the aspect ratio of the paper sheet 4 conveyed from the single separating means 11, and determines whether the conveying direction of the paper sheet 4 is the longitudinal direction or the short direction of the paper sheet 4. Determination is made and the transport direction is changed so that the paper sheet 4 transported in the short direction is transported in the longitudinal direction. More specifically, when it is determined that the paper sheet 4 is transported in the short direction, the direction changing unit 12 performs the paper sheet 4 (for example, FIG. The sheet 4-3) of c) is rotated 90 degrees and converted so as to be conveyed in the longitudinal direction. When the paper sheet 4 is transported in the short direction, the transport of the paper sheet 4 becomes unstable and there is a risk that the paper sheet 4 may cause skew or JAM during the transport. The conveyance direction is converted so that the leaves 4 are conveyed in the longitudinal direction. The direction changing unit 12 does not change the conveyance direction for the paper sheet 4 (for example, the paper sheet 4-2 in FIG. 6C) that has been conveyed in the longitudinal direction from the beginning. The paper sheets 4 that have passed through the direction changing means 12 are conveyed on a conveyor inclined at a predetermined angle (for example, 45 degrees) and conveyed to the detecting means 8.

  In FIG. 6D, the detection means 8 measures the thickness, unevenness, hardness, front and back, etc. of the paper sheet 4 conveyed from the direction changing means 12.

  A detailed configuration of the detection means 8 is shown in FIG. The detection unit 8 includes a control unit 81, a measurement unit 82, and a storage unit 83.

  The control means 81 of the detection means 8 controls each means of the detection means 8 described later. Further, the control means 81 is a machine for which the measured paper sheets 4 are sorted by the paper sheet sorting device 9 after sorting the paper sheets 4 based on the measurement result of the thickness of the paper sheets 4 by the measuring means 82. It is determined whether or not the paper sheet 4 is suitable for processing (for example, classification by postal code using a flat sorter). In addition, the control unit 81 transmits information such as the thickness of the paper sheet 4 measured by the measuring unit 82 and stored in the storage unit 83 to the stacking unit 2 described later. For example, the control means 81 may transmit information such as the thickness of the paper sheet 4 to the stacking means 2 every time the measuring means 82 measures information such as the thickness of the paper sheet 4. Further, for example, the control means 81 transmits information such as the thickness of the paper sheets 4 to the accumulating means 2 only for the paper sheets 4 determined to be machine-processable after sorting by the paper sheet sorting apparatus 9. . For example, the control unit 81 may be configured by a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. For example, the CPU of the control unit 81 may control each unit of the detection unit 8 based on a program read from the ROM. Further, the CPU of the control means 81 may read and execute the program from a storage medium storing a computer-readable program using a reading device (not shown).

  The measuring means 82 of the detecting means 8 measures the thickness, unevenness, hardness, front and back, etc. of the paper sheet 4 conveyed from the direction changing means 12.

  The storage means 83 of the detection means 8 stores information such as the thickness, unevenness, hardness, front and back, etc. of the paper sheet 4 measured by the measurement means 82. For example, the storage unit 83 may be configured with a hard disk or the like.

  The paper sheet 4 determined by the control means 81 to be machine-processed after sorting by the paper sheet sorting device 9 is conveyed to the stacking means 2. Further, the paper sheet 4 determined that the machine processing after the sorting by the paper sheet sorting device 9 is impossible is passed through the stacking means 2 and transported to the atypical transport means 13. For example, as shown in FIGS. 6 (e) and 6 (f), the paper sheet 4-2 determined by the detection means 8 to be processable by the machine processing after sorting by the paper sheet sorting device 9 is sent to the stacking means 2. Be transported. Also, as shown in FIGS. 6E and 6G, the paper sheet 4-3 determined to be unprocessable by the mechanical processing after sorting by the paper sheet sorting device 9 passes through the stacking means 2, It is conveyed to the standard conveying means 13.

  The stacking unit 2 stacks the paper sheets 4 conveyed from the detection unit 8 in the stacking box 5. The accumulating means 2 will be described later.

  The non-standard conveyance means 13 conveys the conveyed paper sheet 4 to another sorter, and the paper sheet 4 is subjected to sorting processing or the like by the other sorter. For example, as shown in FIG. 6G, the paper sheet 4-3 is transported to the atypical transport means 13, and is subjected to sorting processing by other sorters or the like.

  As shown in FIGS. 5 and 8, the empty container conveyor 14 conveys the empty stacking box 5 into which the paper sheets 4 are not loaded to the swinging conveyor means 6. The empty stacking box 5 passes under the stacking means 2, is set on the swing conveyor means 6, and waits for the paper sheets 4 discharged from the stacking means 2.

  As shown in FIGS. 5 and 8, the full container conveyor 15 receives the stacking box 5 filled with paper sheets 4 from the swinging conveyor means 6 and performs the next mechanical processing on the full stacking box 5. Transport to. For example, the full container conveyor 15 conveys the stacking box 5 filled with paper sheets 4 to a flat sorter or the like, and then the conveyed paper sheets 4 are sorted by postal code using the flat sorter or the like. Etc. are performed.

  As shown in FIGS. 5 and 8, the oscillating conveyor means 6 mounts an empty stacking box 5 that is transported from an empty container conveyor 14. The swinging conveyor means 6 moves the stacking box 5 mounted on the swinging conveyor means 6 in accordance with the position where the stacking means 2 discharges the paper sheets 4. Further, when the swinging conveyor means 6 receives a notification from the stacking means 2 that the second chute 25 appears, the swinging conveyor means 6 moves the stacking box 5 mounted on the swinging conveyor means 6. Further, when the swing conveyor means 6 receives a notification that the stacking box 5 is full from the stacking means 2, the swinging conveyor means 6 transports the full stacking box 5 to the full container conveyor 15. The swing conveyor means 6 will be described later.

  The control means (not shown) of the paper sheet sorting apparatus 9 controls the above-described means and conveyors. Each means, each conveyor, and the like described above perform each operation described above based on a control instruction from the control means.

  Next, the stacking means 2 and the swing conveyor means 6 will be described in detail.

  A detailed configuration of the stacking means 2 is shown in FIG. The stacking unit 2 includes a control unit 21, a stopper 22, a discharge roller 23, a first chute 24, a second chute 25, and a storage unit 26.

  The control means 21 of the stacking means 2 controls each means of the stacking means 2 described later. The control means 21 of the stacking means 2 receives information such as the thickness of the paper sheets 4 transmitted from the detecting means 8 and receives the total thickness (paper sheets) of the paper sheets 4 stacked in the stacking box 5. 4 accumulation amount) is calculated. For example, each time the control unit 21 receives the thickness information of the paper sheet 4 transmitted from the detection unit 8, the control unit 21 accumulates the thickness of the paper sheet 4 and accumulates the paper sheets stacked in the stacking box 5. The total thickness of class 4 is calculated.

  The control means 21 determines whether or not the calculated total thickness has reached a predetermined threshold value. More specifically, the control means 21 is based on a predetermined threshold value (hereinafter referred to as the first threshold value) for causing the second chute 25 to appear and information on the calculated total thickness of the paper sheet 4. It is determined whether or not the second chute 25 appears. Further, the control means 21 uses a predetermined threshold value (hereinafter referred to as a second threshold value) for determining whether or not the stacking box 5 is full and information on the calculated total thickness of the paper sheet 4. Based on this, it is determined whether or not the stacking box 5 is filled with the stacked sheets 4. The first and second threshold values are stored in the storage unit 26 (to be described later) of the stacking unit 2.

  The first threshold value is set on the basis of a predetermined distance that is a distance (height) at which the paper sheets 4 put into the stacking box 5 described with reference to FIG. The

  Here, the predetermined distance is the design value of the paper sheet sorting device 9 such as the distance between the first chute 24 and the stacking box 5, the input speed of the paper sheets 4, the angle of the first chute 24, and the paper to be handled. This value is determined by the type (size and thickness) of the leaves 4 and the size of the collection box 5 to be used. For example, the user of the paper sheet sorting device 9 determines a predetermined distance based on the design value, the type of the paper sheet 4, and the like.

  For example, the maximum size of the paper sheet 4 is 300 mm in the short direction, the distance between the first chute 24 and the stacking box 5 is about 350 mm, the input speed of the paper sheet 4 is about 1 m / sec, When the throwing angle is 30 degrees, the predetermined value is 100 mm.

  For example, when the distance from the contact position of the paper sheets 4 thrown in by the first chute 24 to the bottom of the stacking box 5 is the same value as the predetermined distance, the upper limit value of the first threshold is The distance is not more than the predetermined distance. In this case, the lower limit value of the first threshold value is the difference between the first threshold value and the distance from the contact position of the paper sheets 4 thrown in by the second chute 25 to the bottom of the stacking box 5. Can be set within a range not exceeding the distance. For example, when the distance from the contact position of the paper sheets 4 loaded by the second chute 25 to the bottom of the stacking box 5 is 170 mm and the predetermined distance is 100 mm, the lower limit of the first threshold is 70 mm. Therefore, in this example, the first threshold can be adjusted between 70 and 100 mm.

  The second threshold is set based on the predetermined distance, the size, capacity, height, and the like of the collection box 5. For example, the user of the paper sheet sorting device 9 sets the second threshold value based on information such as the size, capacity, and height of the stacking box 5 and stores it in the storage means 26.

  When the control means 21 of the stacking means 2 determines that the calculated total thickness has reached the first threshold, the control means 21 causes the second chute 25 to appear and the second chute 25 to The swinging conveyor means 6 is notified of the appearance. When the control means 21 determines that the calculated total thickness has not reached the first threshold value, the control means 21 does not notify the oscillating conveyor means 6 and continues to collect the accumulation means 2. Collects paper sheets 4.

  When the control means 21 determines that the calculated total thickness has reached the second threshold value, the control means 21 indicates that the stacking box 5 is full of paper sheets 4 and the swing conveyor means 6. Notify When the control means 21 determines that the calculated total thickness has not reached the second threshold, the control means 21 does not notify the swing conveyor means 6 and the stacking means 2 continues. Then, the paper sheets 4 are accumulated.

  For example, the control means 21 may be configured by a CPU, ROM, RAM, and the like. Further, for example, the CPU of the control means 21 may control each means of the accumulation means 2 based on a program read from the ROM. Further, the CPU of the control means 21 may read and execute a program from a storage medium storing a computer-readable program using a reading device (not shown).

  The stopper 22 of the stacking means 2 transfers the paper sheets 4 conveyed from the detection means 8 on the conveyor inclined at a predetermined angle (for example, 45 degrees) to the stacking box 5 set on the swinging conveyor means 6. Stop at the discharge position.

  The discharge roller 23 of the stacking means 2 discharges the paper sheets 4 temporarily stopped by the stopper 22 toward the stacking box 5 set on the swinging conveyor means 6. The discharge roller 23 changes the conveyance direction of the paper sheet 4 that has been stopped once by 90 degrees, and discharges the paper sheet 4 toward the stacking box 5.

  The first chute 24 of the stacking means 2 guides the paper sheets 4 discharged by the discharge roller 23 toward the stacking box 5 set on the swing conveyor means 6. The paper sheets 4 guided by the first chute 24 are put into the stacking box 5. For example, in FIG. 6 (e), the paper sheet 4-2 is transported to the stacking means 2 in the longitudinal direction. Therefore, the paper sheet 4-2 whose transport direction is changed by 90 degrees is illustrated in FIG. As shown to f), it will be thrown into the stacking box 5 in a short direction. The paper sheets 4 thrown into the stacking box 5 by the first chute 24 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 and are stacked and stacked. Further, the first distance is set so that the distance from the contact position of the inserted paper sheet 4 to the bottom of the stacking box 5 is equal to or less than the predetermined distance so that the paper sheet 4 does not rise in the stacking box 5. The input position of the paper sheet 4 by the chute 24 is initially set. For this reason, the input paper sheet 4 does not stand up in front of the stacking box 5. Details of the input position of the paper sheet 4 by the first chute 24 will be described later.

  The second chute 25 of the stacking means 2 is information on the total thickness of the paper sheets 4 accumulated in the stacking box 5 calculated by the control means 21 of the stacking means 2 (stacking of the paper sheets 4 in the stacking box 5). The paper sheets 4 appearing according to the amount and discharged in the same manner as the first chute 24 are guided in the direction of the stacking box 5. Information on the total thickness of the paper sheets 4 accumulated in the accumulation box 5 is calculated based on information such as the thickness of the paper sheets 4 received from the detection means 8 by the control means 21 of the accumulation means 2. More specifically, the second chute 25 is stored until the control unit 21 of the stacking unit 2 determines that the total thickness of the stacked paper sheets 4 has reached the first threshold, Appears when it is determined that the total thickness of the accumulated paper sheets 4 has reached the first threshold. The paper sheets 4 put into the stacking box 5 by the second chute 25 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 to be stacked and stacked. Further, the distance from the contact position of the inserted paper sheet 4 to the uppermost paper sheet 4 stacked in the stacking box 5 is set so that the paper sheet 4 does not rise in the stacking box 5. The insertion position of the paper sheet 4 by the second chute 25 is set so as to be equal to or less than this distance. For this reason, the input paper sheet 4 does not stand up in front of the stacking box 5. Furthermore, since the contact position of the input paper sheet 4 is a predetermined distance away from the uppermost paper sheet 4 accumulated in the accumulation box 5, the contact with the accumulated paper sheet 4 The input paper 4 does not cause JAM. Details of the input position of the paper sheet 4 by the second chute 25 will be described later.

  The storage means 26 of the accumulation means 2 stores the first and second threshold values described above. Further, the storage unit 26 stores information such as the thickness of the paper sheet 4 transmitted from the detection unit 8. For example, the user of the paper sheet sorting device 9 sets the first and second thresholds based on the above-described predetermined distance and the like, and stores them in the storage unit 26 in advance. For example, the storage unit 26 may be configured with a hard disk or the like.

  The input position of the paper sheet 4 by the first chute 24 and the second chute 25, the predetermined distance, the first threshold value, and the second threshold value will be described in detail with reference to FIG. In FIG. 10, L is the predetermined distance described above, L1 is the distance from the contact position x1 of the paper sheets 4 loaded by the first chute 24 to the bottom of the stacking box 5, and the paper loaded by the second chute 25. The distance from the contact position x2 of the leaves 4 to the uppermost paper sheets 4 '' stacked in the stacking box 5 is L2. Further, L ≧ L1 and L ≧ L2. In FIG. 10, the other configuration of the paper sheet sorting device 9 is not shown.

  As described above, the first threshold value Lth1 is set based on, for example, the predetermined distance L and the distance L1 + L2 from the contact position x2 of the paper sheets 4 thrown in by the second chute 25 to the bottom of the stacking box 5. The That is, Lth1 is determined to be a value satisfying (L1 + L2) −Lth1 ≦ L. The second threshold Lth2 is determined based on the predetermined distance L, the size of the stacking box 5, and the like. In the example of FIG. 10, Lth1 = L1.

  As shown in FIG. 10 a, the paper sheets 4 put into the stacking box 5 by the first chute 24 are stacked in the stacking box 5 after contacting a position away from the bottom of the stacking box 5 by L1. Here, since L ≧ L1, the inserted paper sheets 4 do not stand up in front of the stacking box 5. The input position of the paper sheet 4 by the first chute 24 (the distance from the contact position of the input paper sheet 4 to the bottom of the stacking box 5) is initially set to be equal to or less than the predetermined distance.

  Assume that the stacking in the stacking box 5 progresses sequentially, and the total thickness of the stacked sheets 4 reaches Lth1 (= L1) which is the first threshold as shown in FIG. 10B. In this case, the control means 21 causes the second chute 25 to appear and continues the accumulation.

  At this time, the paper sheets 4 put into the stacking box 5 by the second chute 25 come into contact with the position L2 away from the uppermost paper sheets 4 '' stacked in the stacking box 5, and then the stacking box 5 is accumulated. Here, since L ≧ L2, the input paper sheet 4 does not rise to the front in the stacking box 5. Further, when the total thickness of the accumulated paper sheets 4 reaches Lth1, the contact position of the inserted paper sheets 4 is shifted from x1 to x2, so that it contacts the paper sheets 4 ''. There is no JAM of the paper sheets 4. The input position of the paper sheet 4 by the second chute 25 (the distance from the contact position of the input paper sheet 4 to the uppermost paper sheet 4 stacked in the stacking box 5) is equal to or less than the predetermined distance. Is set to be

  The paper sheet sorting device 9 accumulates the paper sheets 4 using the second chute 25, and the total thickness of the paper sheets 4 accumulated in the accumulation box 5 reaches the second threshold value Lth2. The control means 21 determines that the stacking box 5 is full.

  In the above example, the first threshold value Lth1 is set based on the predetermined distance L and the distance L1 + L2 from the contact position x2 of the paper sheets 4 thrown in by the second chute 25 to the bottom of the stacking box 5. However, it is not limited to this. For example, the first threshold value Lth1 is set in advance, and based on the predetermined distance L and the first threshold value Lth1, the bottom of the stacking box 5 from the contact position x2 of the paper sheets 4 thrown in by the second chute 25 You may set the distance to. For example, when the predetermined distance is 100 mm and the first threshold is 100 mm, the upper limit value of the distance from the contact position x2 of the paper sheets 4 thrown in by the second chute 25 to the bottom of the stacking box 5 is 200 mm. Become.

  A detailed configuration of the swing conveyor means 6 is shown in FIGS.

  The swing conveyor means 6 includes a control means 61, a swing conveyor 7, an intermediate stopper 62, and a final stopper 63.

  The control means 61 controls each component of the swing conveyor means 6 described later. When the stacking unit 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has reached the first threshold, the control unit 61 notifies the stacking unit 2 of the notification. Receives and drives the swing conveyor 7. The swing conveyor 7 moves the loaded collection box 5 to a position where it comes into contact with the final stopper 63. When the stacking unit 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has reached the second threshold, the control unit 61 notifies the stacking unit 2 of that fact. Then, the swing conveyor 7 is driven, and the stacking box 5 filled with the paper sheets 4 is conveyed from the swing conveyor 7 to the full container conveyor 15.

  The swing conveyor 7 is mounted with an empty stacking box 5 conveyed from the empty container conveyor 14 and adjusts the position of the stacking box 5 mounted on the swing conveyor 7. Further, the oscillating conveyor 7 has a position of the stacking box 5 mounted according to the total thickness (stacking amount) of the paper sheets 4 stacked on the stacking box 5 mounted on the swinging conveyor 7. Make adjustments. Further, the swing conveyor 7 is rotated in a state where the stacking box 5 is mounted, and adjusts the position of the stacking box 5 so that the paper sheets 4 are put into the mounted stacking box 5. Further, the swinging conveyor 7 conveys the full stacking box 5 to the full container conveyor 15 when the stacking box 5 mounted on the swinging conveyor 7 is full of paper sheets 4.

  The intermediate stopper 62 and the final stopper 63 are provided on the swing conveyor 7 and perform positioning of the stacking box 5 mounted on the swing conveyor 7 on the swing conveyor 7.

  The intermediate stopper 62 is placed on the swing conveyor 7 at a position where it comes into contact with the intermediate stopper 62 until the stacking means 2 determines that the total thickness of the sheets 4 stacked in the stacking box 5 has reached the first threshold. The loaded collection box 5 is stopped.

  The final stopper 63 is placed on the swing conveyor 7 at a position where it contacts the final stopper 63 until the stacking means 2 determines that the total thickness of the sheets 4 stacked in the stacking box 5 has reached the second threshold. The loaded collection box 5 is stopped.

  The angle of the first chute 24 and the position of the stacking box 5 set on the swinging conveyor means 6 are the distance from the contact position of the paper sheets 4 placed in the stacking box 5 to the bottom of the stacking box 5. Is adjusted to be equal to or less than the predetermined distance described above.

  Further, the angle of the second chute 25 and the position of the stacking box 5 set on the swinging conveyor means 6 are stacked in the stacking box 5 from the contact position of the paper sheets 4 put in the stacking box 5. The distance to the uppermost sheet 4 is adjusted to be equal to or less than the predetermined distance described above.

  Here, the predetermined distance is a distance at which the phenomenon of rising in front of the paper sheet 4 described with reference to FIG. 1a does not occur. That is, according to the present embodiment, the phenomenon that the paper sheet 4 rises forward and the JAM of the paper sheet 4 does not occur.

  12 to 14 describe in detail the operations of the stacking means 2 and the swinging conveyor means 6 of the paper sheet sorting device 9.

  As shown in FIG. 12, the empty stacking box 5 transported on the empty container conveyor 14 is transported onto the swinging conveyor 7 of the swinging conveyor means 6 and is shaken by the intermediate stopper 62 on the swinging conveyor 7. Stops at a predetermined position on the moving conveyor 7.

  Thereafter, as shown in FIG. 13, the swing conveyor 7 is rotated by a predetermined angle, and the empty stacking box 5 is moved to a position where the paper sheets 4 are inserted. More specifically, as shown in FIGS. 12 and 13, the swinging conveyor 7 rotates counterclockwise, and the side of the full container conveyor 15 side of the opening surface of the stacking box 5 on the swinging conveyor 7 is lowered, The position of the stacking box 5 is adjusted so that the paper sheets 4 guided from the first chute 24 of the stacking means 2 are put into the stacking box 5. The angle of the first chute 24 and the position of the stacking box 5 set on the swinging conveyor means 6 are such that the distance from the contact position of the paper sheets 4 placed in the stacking box 5 to the bottom of the stacking box 5 is It is adjusted to be equal to or less than the predetermined distance described above.

  After the stacking box 5 on the oscillating conveyor 7 reaches a position waiting for the paper sheets 4 to be put in, the discharge roller 23 of the stacking means 2 is conveyed from the detecting means 8 and is a stopper 22 (not shown in FIG. 13) of the stacking means 2. The paper sheet 4 that has been stopped is discharged.

  The discharged paper sheets 4 are guided toward the stacking box 5 by the first chute 24 and are put into the stacking box 5. The paper sheets 4 loaded by the first chute 24 are stacked from the contact position of the loaded paper sheets 4 depending on the charging angle of the first chute 24 and the position of the stacking box 5 on the swing conveyor 7. 5 It is thrown in so that the distance to bottom part may become below the said predetermined distance. For this reason, the inserted paper sheets 4 are turned forward in the accumulation box 5 and do not stand up, and the accumulation disturbance in the accumulation box 5 does not occur. At this time, the second chute 25 is stored as shown in FIG. 13 and is not used for loading the paper sheets 4.

  The control means 21 of the stacking means 2 receives information such as the thickness of the paper sheet 4 that is transmitted each time the detection means 8 measures. Each time the control means 21 of the stacking means 2 receives information such as the thickness of the paper sheet 4, the storage means 26 stores the information, and the control means 21 stores the information such as the received thickness etc. The total thickness of the paper sheets 4 accumulated in 5 is calculated. When the total thickness of the paper sheets 4 accumulated in the accumulation box 5 is calculated, the control means 21 compares the calculated total thickness of the paper sheets 4 with the first threshold value and accumulates them. It is determined whether or not the total thickness of the paper sheet 4 has reached the first threshold value. If the control means 21 determines that the total thickness of the accumulated paper sheets 4 has not reached the first threshold, the accumulating means 2 continues to input and stack the paper sheets 4.

  A case where the control unit 21 determines that the total thickness of the accumulated paper sheets 4 has reached the first threshold will be described with reference to FIG. In this case, the control means 21 of the stacking means 2 causes the second chute 25 having a different throwing angle from the first chute 24 to appear. Further, the control means 21 transmits to the swing conveyor means 6 that the accumulated amount of the paper sheets 4 in the accumulation box 5 has reached the first threshold value. The control means 61 of the oscillating conveyor means 6 that has received the fact that the first threshold value has been reached from the control means 21 drives the oscillating conveyor 7 and hits the stacking box 5 mounted on the oscillating conveyor 7 against the final stopper 63. The sheet is moved to the position, and the feeding angle of the paper sheets 4 to be fed into the stacking box 5 is adjusted.

  The angle of the second chute 25 and the position of the stacking box 5 set on the swinging conveyor means 6 are such that the distance from the contact position of the paper sheets 4 placed in the stacking box 5 to the bottom of the stacking box 5 is It is adjusted to be equal to or less than the predetermined distance described above.

  Accordingly, the paper sheets 4 thrown in by the second chute 25 are moved away from the contact position of the thrown paper sheets 4 depending on the throwing angle of the second chute 25 and the position of the stacking box 5 on the swing conveyor 7. The paper is loaded so that the distance to the uppermost sheet 4 accumulated in the accumulation box 5 is equal to or less than a predetermined distance. For this reason, the paper sheets 4 thrown in by the second chute 25 do not rotate forward in the stacking box 5 and the stacking disorder in the stacking box 5 does not occur. Furthermore, the paper sheets 4 thrown in by the second chute 25 can be stacked in the stacking box 5 without coming into contact with the paper sheets 4 stacked in the stacking box 5. 4 JAM can be prevented. In the case of FIG. 14, the paper sheet 4 is put into the stacking box 5 through the first chute 24 and the second chute 25. As shown in FIG. 14, the throwing angle of the second chute 25 is shallower than the throwing angle of the first chute 24. For this reason, the sheet 4 loaded by the first chute 24 rises in the stacking box 5 at a predetermined distance where the sheet 4 loaded by the second chute 25 does not rise in the stacking box 5. It becomes larger than the predetermined distance without anything. Therefore, based on a predetermined distance at which the paper sheets 4 thrown in by the second chute 25 do not rise in the stacking box 5, the throwing angle of the second chute 25 and the stacking box 5 on the swinging conveyor 7. May be determined.

  The control unit 21 of the stacking unit 2 stacks the paper sheets 4 using the second chute 25 after the appearance of the second chute 25. The control means 21 calculates the total thickness of the paper sheets 4 stacked in the stacking box 5 based on information such as the thickness of the paper sheets 4 transmitted from the detection means 8. When calculating the total thickness of the paper sheets 4 stacked in the stacking box 5, the control means 21 compares the calculated total thickness of the paper sheets 4 with the second threshold value, and calculates the calculated paper sheets. It is determined whether or not the total thickness of the leaves 4 has reached the second threshold value. When the control unit 21 determines that the calculated total thickness of the paper sheets 4 has not reached the second threshold, the stacking unit 2 continues to input and stack the paper sheets 4.

  When the control means 21 determines that the total thickness of the stacked paper sheets 4 has reached the second threshold value (the stacking box 5 that is stacking is full of paper sheets 4), The control means 21 transmits to the oscillating conveyor means 6 that the stacking box 5 is full of paper sheets 4.

  When the control means 61 of the swinging conveyor means 6 receives a notification from the stacking means 2 that the stacking box 5 is full, the swinging conveyor 7 is driven, and the swinging conveyor 7 is full. The box 5 is conveyed to the full container conveyor 15.

  When the full stacking box 5 is conveyed from the swinging conveyor means 6 to the full container conveyor 15, the control means 21 of the stacking means 2 stores the second chute 25 that has appeared and swings. The stacking operation of the paper sheets 4 conveyed from the detection means 8 is performed using the first chute 24 to the empty stacking box 5 set next on the conveyor means 6. Further, after the stacking box 5 filled with the oscillating conveyor means 6 is transported to the full container conveyor 15, the control means 21 of the stacking means 2 provides the information on the calculated total thickness of the paper sheets 4 to the stacking means 2. You may delete from the memory | storage means 26.

  FIG. 15 is an operation flowchart relating to the stacking operation of the paper sheet sorting apparatus 9 according to the present embodiment.

  The detecting means 8 of the paper sheet sorting device 9 measures information such as the thickness of the paper sheet 4 conveyed from the direction changing means 12. The detection unit 8 transmits information such as the detected thickness of the paper sheet 4 to the stacking unit 2. For example, the detection unit 8 transmits the thickness information to the stacking unit 2 every time information such as the thickness of the paper sheet 4 is detected. The detection unit 8 conveys the paper sheet 4 whose thickness information is detected to the stacking unit 2. The stacking unit 2 stacks the sheets 4 using the first chute 24 that guides the sheets 4 conveyed from the detection unit 8 toward the stacking box 5 (S1501). The first chute 24 guides the paper sheets 4 toward the stacking box 5 and puts the paper sheets 4 into the stacking box 5. At this time, the paper sheets 4 put into the stacking box 5 by the first chute 24 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 to be stacked and stacked. The angle of the first chute 24 and the position of the stacking box 5 set on the swinging conveyor means 6 are as described above from the contact position of the paper sheets 4 placed in the stacking box 5 to the bottom of the stacking box 5. The distance is adjusted so as to be equal to or less than a predetermined distance. For this reason, the input paper sheet 4 does not stand up in front of the stacking box 5.

  The stacking unit 2 receives information such as the thickness of the paper sheet 4 transmitted from the detection unit 8 and stores the information in the storage unit 26 of the stacking unit 2. Further, the control means 21 of the stacking means 2 accumulates the stored thickness information of the paper sheets 4 and calculates the total thickness of the paper sheets 4 stacked in the stacking box 5 (the stacking amount of the paper sheets 4). Calculate (S1502).

  The control unit 21 of the stacking unit 2 determines whether or not the calculated total thickness of the paper sheets 4 has reached the first threshold value stored in the storage unit 26 of the stacking unit 2 (S1503).

  When the control means 21 of the stacking means 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has not reached the first threshold (S1503, NO), the stacking means 2 The leaf 4 is continuously accumulated (return to S1501).

  When the control means 21 of the stacking means 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has reached the first threshold (S1503, YES), the control means 21 is stored. The second shoot 25 that has been made appears (S1504). Furthermore, the control means 21 transmits to the swing conveyor means 6 that the total thickness of the paper sheets 4 has reached the first threshold value. The control means 61 of the oscillating conveyor means 6 that has received the fact that the total thickness of the paper sheets 4 has reached the first threshold value drives the oscillating conveyor 7 and is a collection box mounted on the oscillating conveyor 7. 5 is moved to a position in contact with the final stopper 63.

  The detecting means 8 of the paper sheet sorting device 9 measures information such as the thickness of the paper sheet 4 conveyed from the direction changing means 12. The detection unit 8 transmits information such as the detected thickness of the paper sheet 4 to the stacking unit 2. For example, the detection unit 8 transmits the thickness information to the stacking unit 2 every time information such as the thickness of the paper sheet 4 is detected. The detection unit 8 conveys the paper sheet 4 whose thickness information is detected to the stacking unit 2. The stacking means 2 stacks the paper sheets 4 using the second chute 25 (S1505). The paper sheets 4 thrown into the stacking box 5 by the second chute 25 come into contact with the wall surface inside the stacking box 5 and then fall toward the bottom of the stacking box 5 and are stacked. The angle of the second chute 25 and the position of the stacking box 5 set on the swinging conveyor means 6 are the uppermost stage stacked in the stacking box 5 from the contact position of the paper sheets 4 put in the stacking box 5. The distance to the paper sheet 4 is adjusted to be a predetermined distance or less. For this reason, the input paper sheet 4 does not stand up in front of the stacking box 5. Furthermore, since the contact position of the input paper sheet 4 is a predetermined distance away from the uppermost paper sheet 4 accumulated in the accumulation box 5, the contact with the accumulated paper sheet 4 The input paper 4 does not cause JAM.

  The stacking unit 2 receives information such as the thickness of the paper sheet 4 transmitted from the detection unit 8 and stores the information in the storage unit 26 of the stacking unit 2. Further, the control means 21 of the stacking means 2 accumulates the stored thickness information of the paper sheets 4 and calculates the total thickness of the paper sheets 4 stacked in the stacking box 5 (the stacking amount of the paper sheets 4). Calculate (S1506).

  The control means 21 of the stacking means 2 determines whether or not the calculated total thickness of the paper sheets 4 has reached the second threshold value stored in the storage means 26 (S1507).

  When the control means 21 of the stacking means 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has not reached the second threshold (S1507, NO), the stacking means 2 The paper sheets 4 are continuously accumulated using the second chute 25 (return to S1505).

  When the control means 21 of the stacking means 2 determines that the total thickness of the paper sheets 4 stacked in the stacking box 5 has reached the second threshold (S1507, YES), the control means 21 The fact that the total thickness of the class 4 has reached the second threshold value is transmitted to the swing conveyor means 6.

  The control means 61 of the oscillating conveyor means 6 that has received that the total thickness of the paper sheets 4 has reached the second threshold value drives the oscillating conveyor 7, and the paper sheets mounted on the oscillating conveyor 7. The collection box 5 filled with the category 4 is transported to the full container conveyor 15 (S1508). After transporting the full stacking box 5, the control unit 21 of the stacking unit 2 stores the second chute 25 that has appeared. Thereafter, the above operation is repeated for the empty stacking box 5 conveyed from the empty container conveyor 14.

  Therefore, according to the present embodiment, when the paper sheets 4 are stacked in the predetermined stacking box 5, it is possible to prevent a phenomenon that the paper sheets 4 thrown into the stacking box 5 stand. Furthermore, since the JAM due to the collision of the paper sheets 4 in the stacking box 5 can be avoided, the operation rate of the apparatus can be increased without stopping the paper sheet sorting device 9.

  Further, since it is possible to prevent the paper sheets 4 accumulated in the collection box 5 from being disturbed, it is necessary to arrange the paper sheets 4 by a human hand in a subsequent process after the collection into the collection box 5. There is no.

  In the present embodiment, the stacking operation of the paper sheets 4 in the paper sheet sorting apparatus 9 has been described, but the present invention is not limited to this. For example, the same stacking operation and stacking method can be adopted for various sorters such as a flat sorter.

  As mentioned above, although each embodiment of this invention was described, this invention is not limited to each above-described embodiment. The present invention can be implemented based on modifications, substitutions, and adjustments of the embodiments. That is, the present invention includes various modifications and corrections that can be realized in accordance with all the disclosed contents and technical ideas of the present specification. In addition, the drawing reference numerals attached to each drawing are added to each element for convenience as an example for facilitating understanding, and are not intended to limit the present invention to the illustrated embodiment.
