The side view which shows the upstream and downstream conveyance part and timing adjustment part of one Embodiment. The flowchart which shows operation | movement of the paper sheet processing apparatus of one Embodiment.

  Hereinafter, an embodiment will be described with reference to FIGS. 1 to 3. Note that in this specification, one or more examples of other expressions may be attached to each element capable of a plurality of expressions. However, this does not deny that a different expression is given for an element to which no other expression is attached, and does not restrict other expressions not illustrated. Each drawing schematically shows an embodiment, and the size of each element shown in the drawing may differ from the explanation of the embodiment.

  FIG. 1 is a plan view schematically showing a part of the paper sheet processing apparatus 1. The paper sheet processing apparatus 1 is an apparatus that sorts paper sheets P such as mails or letters. In the present specification, the paper sheet is not limited to a single sheet of paper, but includes, for example, a plurality of sheets of paper or articles packed, and a sheet having a certain thickness.

  For example, the paper sheet processing apparatus 1 reads information such as a destination from the paper sheet P, and sorts the paper sheet P based on the information. The sorted paper sheets P are distributed and accumulated in a plurality of stacking units allocated for each section.

  As shown in FIG. 1, the sheet processing apparatus 1 includes a take-out unit 10, an exclusion determination unit 11, an exclusion unit 12, an upstream conveyance unit (twisting unit) 13, a timing adjustment unit 14, and a downstream conveyance unit. (Downstream conveyor) 15 and a control unit 16. A part of the paper sheet processing apparatus 1 shown in FIG. 1 may also be referred to as a paper sheet discharging apparatus. The part of the paper sheet processing apparatus 1 sends out the paper sheets P one by one at roughly constant timing.

  A plurality of paper sheets P stacked in a standing state are set in the take-out unit 10. The take-out unit 10 includes an endless belt that conveys the paper sheet P and a pressing unit that presses the set plurality of paper sheets toward the belt. The belt conveys the pressed paper sheets P one by one to the exclusion determination unit 11. The take-out unit 10 carries out the paper sheet P intermittently with a constant time (constant pitch) or a constant distance (constant gap). For example, the take-out unit 10 carries out the paper sheet P every 400 [ms].

  The exclusion determination unit 11 selects the paper sheet P delivered from the take-out unit 10. For example, the exclusion determination unit 11 determines whether the conveyed paper sheet P exceeds a specified length, height, or weight. Based on the determination, the exclusion determination unit 11 determines whether the conveyed paper sheet P should be excluded. The exclusion determination unit 11 conveys the paper sheet P to the exclusion unit 12 and sends a signal regarding whether or not the conveyed paper sheet P should be excluded to the exclusion unit 12.

  The exclusion unit 12 has, for example, a branched conveyance path. When the exclusion unit 12 receives a signal from the exclusion determination unit 11 that the conveyed paper sheet P is to be excluded, the exclusion unit 12 excludes the conveyed paper sheet P from the conveyance path. The rejection unit 12 conveys the paper sheet P to the upstream conveyance unit 13 when receiving a signal from the exclusion determination unit 11 that the conveyed paper sheet P should not be excluded.

  The upstream conveyance unit 13 conveys the paper sheet P conveyed in the standing position while twisting by 90 °. In other words, the upstream conveyance unit 13 changes the paper sheet P from the standing state to the horizontal state in the conveyance process. In order to twist the paper sheet P, the upstream transport unit 13 includes a plurality of rollers that are inclined at different angles and an endless belt that is stretched over the plurality of rollers. The paper sheet P is transferred from the standing state to the horizontal state by being conveyed by the roller and the belt.

  FIG. 2 is a side view showing the upstream conveyance unit 13, the timing adjustment unit 14, and the downstream conveyance unit 15. In FIG. 2, the upstream transport unit 13 and the downstream transport unit 15 are partially shown. As shown in FIG. 2, the upstream transport unit 13 further includes a pair of first transport units 21 and a second transport unit (lower surface limited transport belt unit) 22.

  The pair of first transport units 21 are disposed upstream of the second transport unit 22 in the transport path of the paper sheet P. In the present specification, the downstream is the traveling direction side of the paper sheet P in the conveyance path of the paper sheet P, and the upstream is the opposite side of the downstream side. The second transport unit 22 is disposed between the first transport unit 21 and the timing adjustment unit 14.

  The pair of first transport section 21 and second transport section 22 each have a plurality of rollers 24 and an endless belt 25. The belt 25 is stretched around a plurality of rollers 24. The roller 24 moves the belt 25 by being rotated by a driving device such as a motor. The belt 25 moves at a constant normal speed. The normal speed is, for example, 2.3 [m / s]. The take-out unit 10, the exclusion determination unit 11, and the exclusion unit 12 also move at the normal speed. The belt 25 moves along the transport path of the paper sheet P.

  The pair of first transport parts 21 are respectively disposed below and above the transport path of the paper sheet P. The pair of first transport units 21 transports the paper sheet P transported in a horizontal state to the second transport unit 22.

  The second transport unit 22 is disposed below the transport path of the paper sheet P. The second transport unit 22 supports the paper sheet P transported from the first transport unit 21 from below and transports it to the timing adjustment unit 14. In other words, the second transport unit 22 supports and transports the paper sheet P only from the lower surface.

  The upper part of the second transport part 22 is opened. For example, a guide may be provided above the second transport unit 22. The guide is disposed so as to form a gap with the paper sheet P conveyed by the second transport unit 22. The paper sheet P is transported away from the guide.

  The timing adjustment unit 14 is disposed between the upstream conveyance unit 13 and the downstream conveyance unit 15. The timing adjustment unit 14 sends the paper sheet P conveyed from the upstream conveyance unit 13 to the downstream conveyance unit 15 at an appropriate timing. The timing adjustment unit 14 includes a transfer unit 31, a first detection unit 32 (paper sheet intrusion confirmation sensor), and a second detection unit 33 (paper sheet discharge confirmation sensor).

  The transfer unit 31 has a pair of rollers 35. The pair of rollers 35 are arranged above and below the conveyance path of the paper sheet P, respectively. The upper roller 35 is positioned vertically above the lower roller 35. The arrangement of the pair of rollers 35 is not limited to this. The pair of rollers 35 discharges the paper sheet P to the downstream conveyance unit 15. Each of the pair of rollers 35 is rotated by a driving device such as a servomotor.

  The roller 35 is normally operated so as to feed the paper sheet P at the same normal speed (2.3 [m / s]) as that of the upstream conveyance unit 13. The rotation speed of the roller 35 can be changed. The transfer unit 31 is not limited to the pair of rollers 35, and may include another device that can change the conveyance speed of the paper sheet P, such as a conveyor.

  The first detection unit 32 is disposed upstream of the transfer unit 31. The 1st detection part 32 is located between the transfer part 31 and the 2nd transport part 22, for example. The first detection unit 32 is, for example, an optical sensor. The first detection unit 32 detects the passing paper sheet P.

  The second detection unit 33 is disposed downstream of the transfer unit 31. The 2nd detection part 33 is located between the transfer part 31 and the downstream conveyance part 15, for example. The second detection unit 33 is an optical sensor, for example. The second detection unit 33 detects the passing paper sheet P.

  In addition, the 1st and 2nd detection parts 32 and 33 are not restricted to an optical sensor. The first and second detection units 32 and 33 are, for example, other devices that can detect the passing paper sheet P, such as a mechanical switch that operates by being brought into contact with the transported paper sheet P. It may be.

  The downstream transport unit 15 is located downstream of the timing adjustment unit 14. The downstream conveyance part 15 is a belt conveyor, for example. The downstream transport unit 15 includes, for example, a plurality of rollers and an endless belt 42. The belt 42 is stretched around the plurality of rollers. The roller moves the belt 42 by being rotated by a driving device such as a motor.

  The belt 42 conveys the paper sheet P horizontally, for example. As shown in FIG. 1, the belt 42 conveys the paper sheet P in a direction orthogonal to the direction in which the paper sheet P is discharged from the timing adjustment unit 14. The belt 42 is not limited to this, and for example, the paper sheet P may be conveyed in the same direction as the direction in which the paper sheet P is discharged from the timing adjustment unit 14.

  The belt 42 has a plurality of blades (partitions) 44 arranged at regular intervals. The interval between the adjacent blades 44 is longer than the predetermined width of the paper sheet P, for example. The paper sheet P can enter between adjacent blades 44. In other words, the belt 42 is provided between the adjacent blades 44 and has a plurality of receiving areas 45 for receiving the paper sheets P.

  As shown in FIG. 2, the downstream transport unit 15 is positioned below the transport path of the paper sheet P passing between the pair of rollers 35 of the transfer unit 31 in the vertical direction. That is, the paper sheet P is discharged from above the downstream transport unit 15 by the transfer unit 31 and lands on the downstream transport unit 15.

  The downstream transport unit 15 operates intermittently and transports the paper sheet P. In other words, the downstream transport unit 15 changes between a first state in which the belt 42 is stopped (acceptance permitted state) and a second state in which the belt 42 is moved by the roller 41 (acceptance not permitted state). In the first state, the receiving area 45 of the belt 42 is adjacent to the timing adjustment unit 14. In other words, when the receiving region 45 comes in front of the timing adjustment unit 14 and the downstream transport unit 15 can receive the paper sheet P, the downstream transport unit 15 temporarily stops.

  As described above, the downstream transport unit 15 receives the paper sheet P transported from the upstream transport unit 13 from the timing adjustment unit 14 in the first state. In the second state, the downstream transport unit 15 does not receive the paper sheet P and transports the paper sheet P placed in the receiving area 45.

  As shown in FIG. 1, the control unit 16 is connected to the timing adjustment unit 14 and the downstream transport unit 15. The control unit 16 receives signals from the first and second detection units 32 and 33 of the timing adjustment unit 14.

  Furthermore, the control unit 16 determines whether the downstream transport unit 15 is in the first state or the second state. For example, the downstream transport unit 15 inputs a signal to the control unit 16 when in the first state. The control unit 16 determines that the downstream transport unit 15 is in the first state when the signal is input, and determines that the downstream transport unit 15 is in the second state when the signal is not received. . The control unit 16 controls the timing adjustment unit 14 to release the paper sheet P to the downstream conveyance unit 15 at an appropriate timing.

  Below, with reference to FIG. 3, an example of the conveyance method of the paper sheet P in the paper sheet processing apparatus 1 is demonstrated. FIG. 3 is a flowchart showing a part of the operation of the paper sheet processing apparatus 1. As shown in FIG. 3, when the leading edge of the paper sheet P conveyed from the upstream conveyance unit 13 is detected by the first detection unit 32 (Act 1), the control unit 16 indicates that the downstream conveyance unit 15 is the first conveyance unit 15. Or the second state (Act 2). In other words, the control unit 16 determines whether or not the downstream transport unit 15 can accept the paper sheet P.

  When the downstream transport unit 15 is in the first state, the control unit 16 inputs an acceleration instruction signal to the timing adjustment unit 14. The timing adjustment unit 14 to which the signal is input accelerates the speed at which the transport unit 31 sends the paper sheet P (rotational speed of the roller 35) (Act 3). The transfer unit 31 operates at the normal speed before receiving the signal.

  On the other hand, when the downstream transport unit 15 is in the second state, the control unit 16 inputs a deceleration instruction signal to the timing adjustment unit 14. The timing adjustment unit 14 to which the signal is input decelerates the speed at which the transfer unit 31 sends the paper sheet P (Act 4). That is, the speed at which the transfer unit 31 sends the paper sheet P is slower than the normal speed.

  The paper sheet P is sandwiched between the pair of decelerated rollers 35 and proceeds toward the downstream conveyance unit 15. At this time, the speed of the second transport section 22 of the upstream transport section 13 is the normal speed, and the speed of the roller 35 is slower than the normal speed. Since the upper side of the second transport unit 22 is open, the paper sheet P can escape to the upper side of the second transport unit 22. In other words, the paper sheet P slightly floats on the second transport unit 22 or slides on the second transport unit 22. For this reason, it is suppressed that the paper sheet P decelerated by the roller 35 is damaged by the second transport unit 22 moving at the normal speed.

  When the tip of the paper sheet P conveyed by the roller 35 is detected by the second detection unit 33 (Act 5), the control unit 16 determines whether the downstream conveyance unit 15 is in the first state or the second state. Is determined again (Act 6). In other words, the control unit 16 determines again whether or not the downstream transport unit 15 can accept the paper sheet P.

  When the downstream transport unit 15 is in the first state, the control unit 16 inputs an acceleration instruction signal to the timing adjustment unit 14. The timing adjustment unit 14 to which the signal is input accelerates the speed at which the transfer unit 31 sends the paper sheet P (Act 3). In this case, the speed at which the transfer unit 31 sends the paper sheet P is faster than the normal speed.

  On the other hand, when the downstream conveyance unit 15 is in the second state, the control unit 16 determines whether or not the second detection unit 33 has detected the trailing edge of the paper sheet P (Act 7). For example, if the second detection unit 33 does not detect the paper sheet P after detecting the paper sheet P once, it is determined that the second detection unit 33 has detected the trailing edge of the paper sheet P. The

  When the second detection unit 33 does not detect the trailing edge of the paper sheet P, the control unit 16 inputs a deceleration instruction signal to the timing adjustment unit 14 again. The timing adjustment unit 14 to which the signal is input further reduces the speed at which the transfer unit 31 sends the paper sheet P (Act 8).

  The control unit 16 further determines whether or not the downstream transport unit 15 can accept the paper sheet P at regular intervals (Act 6). For this reason, the control unit 16 determines that the transport unit 31 has a paper sheet at regular intervals unless the downstream transport unit 15 is in the second state and the second detection unit 33 detects the trailing edge of the paper sheet P. The speed at which the leaves P are sent is reduced (Act 8).

  When the second detection unit 33 detects the trailing edge of the paper sheet P, the control unit 16 urgently stops the paper sheet processing apparatus 1 (Act 9). That is, when the paper sheet P is discharged to the downstream transport unit 15 in the second state, the entire paper sheet processing apparatus 1 including the upstream transport unit 13, the timing adjustment unit 14, and the downstream transport unit 15 is stopped. .

  When the paper sheet processing apparatus 1 is urgently stopped, for example, the operator restarts the paper sheet processing apparatus 1 after removing the paper sheet P discharged to the downstream conveyance unit 15 in the second state. For this reason, for example, the paper sheet P rides on the blades 44 of the downstream transport unit 15 and the downstream process such as the division of the paper sheet P is prevented from being affected.

  After the transfer unit 31 decelerates (Act 8), when the downstream transport unit 15 is in the first state (Act 6), the control unit 16 inputs an acceleration instruction signal to the timing adjustment unit 14. The timing adjustment unit 14 to which the signal is input accelerates the speed at which the transfer unit 31 sends the paper sheet P (Act 3).

  By accelerating the speed at which the transport unit 31 sends the paper sheet P, the paper sheet P advances toward the downstream transport unit 15 faster than the normal speed. When the second detection unit 33 detects the trailing edge of the paper sheet P (Act 10), the control unit 16 determines again whether the downstream conveyance unit 15 is in the first state or the second state ( Act11). In other words, the control unit 16 determines whether the paper sheet P has been discharged to the downstream transport unit 15 that can accept the paper sheet P or whether the paper sheet P has been discharged to the downstream transport unit 15 that cannot accept the paper sheet P. to decide.

  When the downstream transport unit 15 is in the first state, the control unit 16 inputs a speed normalization signal to the timing adjustment unit 14. The timing adjustment unit 14 to which the signal is input returns the speed at which the transport unit 31 sends the paper sheet P (rotational speed of the roller 35) to the normal speed (Act 12). In other words, the speed at which the transfer unit 31 sends the paper sheet P is equal to the speed at which the upstream transport unit 13 sends the paper sheet P.

  On the other hand, when the downstream transport unit 15 is in the second state, the control unit 16 urgently stops the paper sheet processing apparatus 1 (Act 9).

  In addition, the control unit 16 is a downstream transport unit after the transfer unit 31 has accelerated (Act 3) and before the second detection unit 33 detects the rear end of the paper sheet P (Act 10). Whether 15 is the first state or the second state may be determined. At this time, when the downstream conveyance unit 15 is in the second state, the control unit 16 may decelerate the transfer unit 31 or urgently stop the sheet processing apparatus 1.

  The conveyance method of the paper sheet P in the paper sheet processing apparatus 1 is not limited to the above method. After the first detection unit 32 detects the paper sheet P, when the downstream transport unit 15 is in the first state, the control unit 16 may accelerate the transfer unit 31 from any state.

  As shown in FIG. 1, the paper sheet P handled by the paper sheet processing apparatus 1 has various thicknesses. In other words, the paper sheet P includes a first transport object P1 and a second transport object P2 that is thinner than the first transport object P1. The paper sheet P includes paper sheets other than the first and second transported objects P1 and P2.

  The normal speed is a speed at which the first conveyed product P1 arrives at the timing adjusting unit 14 when the downstream conveying unit 15 is in the first state. In other words, the normal speed is a speed at which the first conveyed product P1 is conveyed to the downstream conveying unit 15 without being decelerated by the timing adjusting unit 14.

  On the other hand, the second transported product P2 transported at the normal speed reaches the timing adjusting unit 14 before the downstream transport unit 15 enters the first state. In other words, when the second conveyed product P2 reaches the timing adjusting unit 14, the downstream conveying unit 15 is still in the second state.

  As described above, the second conveyed product P2 that is thinner than the first conveyed product P1 reaches the timing adjustment unit 14 earlier than the first conveyed product P1. This is because the first conveyed product P1 collides with, for example, the roller 24 of the first transport unit 21 and time loss occurs. Since the second conveyed product P2 is thinner than the first conveyed product P1, it is difficult to collide with the roller 24 or the like. For this reason, time loss is less likely to occur in the second conveyed product P2 than in the first conveyed product P1.

  As described above, the first conveyed product P1 reaches the timing adjustment unit 14 when the downstream conveyance unit 15 is in the first state. For this reason, the first conveyed product P <b> 1 is discharged to the downstream conveying unit 15 without being decelerated by the timing adjusting unit 14.

  On the other hand, the second conveyed product P2 reaches the timing adjusting unit 14 when the downstream conveying unit 15 is in the second state. For this reason, the 2nd conveyance thing P2 is decelerated by the timing adjustment part 14, and the timing discharged to the downstream conveyance part 15 is adjusted. As described above, the thinner the paper sheet P is, the more the discharge timing is adjusted by the timing adjustment unit 14.

  According to the paper sheet processing apparatus 1 of the above-described embodiment, when the first detection unit 32 disposed upstream of the timing adjustment unit 14 detects the paper sheet P, the downstream conveyance unit 15 performs the paper sheet processing. If the state P is received, the transfer unit 31 is accelerated, and if the state P is not received, the transfer unit 31 is decelerated. In other words, the timing adjustment unit 14 delays the conveyance of the paper sheet P when the downstream conveyance unit 15 is not ready to receive the paper sheet P. Thereby, the paper sheet P can be sent out at an appropriate timing. Furthermore, by adjusting the discharge timing of the paper sheet P only by the transfer unit 31, it is possible to reduce the number of drive devices such as servo motors, and to suppress increase in noise and cost.

  The timing adjustment unit 14 accelerates the transfer unit 31 if the downstream conveyance unit 15 receives the paper sheet P when the second detection unit 33 disposed downstream thereof detects the paper sheet P. If it is not received, decelerate further. In other words, when the downstream conveyance unit 15 still cannot receive the paper sheet P with the leading edge of the paper sheet P coming out of the transfer unit 31, the conveyance of the paper sheet P is further delayed. Thereby, the paper sheet P can be sent out at a more appropriate timing.

  When the second detection unit 33 detects the trailing edge of the paper sheet P, the timing adjustment unit 14 returns the speed of the transfer unit 31 to the normal speed. This facilitates timing adjustment when the first detection unit 32 detects the paper sheet P next time.

  When the second detection unit 33 detects the trailing edge of the paper sheet P, if the downstream transport unit 15 is still in a state where the paper sheet P cannot be received, the paper sheet processing apparatus 1 is stopped urgently. Thereby, for example, the operator can remove the paper sheet P released from the timing adjustment unit 14, and it is possible to suppress the occurrence of problems in later processes.

  The second transport unit 22 immediately before the timing adjustment unit 14 supports the paper sheet P only from one side. For this reason, even if the conveyance speed of the transfer part 31 becomes slow in the timing adjustment part 14, the paper sheet P escapes from the 2nd conveyance part 22. FIG. Thereby, it can suppress that the paper sheet P is rubbed and damaged by the 2nd transport part 22. FIG.

  The transfer unit 31 conveys the paper sheet P by a pair of rollers 35. For this reason, the paper sheet P can be conveyed by applying force to a wide range of the paper sheet P. Therefore, it is possible to prevent the paper sheet P from being damaged due to the force concentrated on a part of the paper sheet P.

  The upstream conveyance unit 13 is operated at the normal speed that reaches the timing adjustment unit 14 at an appropriate timing for the relatively thick first conveyance object P1 and at a slightly early timing for the relatively thin second conveyance object P2. To do. The thin paper sheet P such as the second transport object P2 has a smaller inertia than the thick paper sheet P such as the first transport object P1, and thus the transport speed can be easily changed by the timing adjustment unit 14. Therefore, the paper sheet P can be easily sent out at an appropriate timing.

  According to at least one paper sheet processing apparatus described above, when the first detection unit detects a paper sheet, the transfer unit is accelerated when the downstream transport unit receives the paper sheet, and the downstream unit The transfer unit decelerates when the transport unit is not receiving the paper sheets. Thereby, paper sheets can be sent out at an appropriate timing.
