  The length calculation unit 102 calculates the length of the paper sheet P in the transport direction X based on the detection result of the length measurement sensor 98. For example, the length calculation unit 102 acquires, from the length measurement sensor 98, information indicating the timing T1 when the leading edge of the paper sheet P has passed and the timing T2 when the trailing edge of the paper sheet P has passed. The length calculation unit 102 calculates the length of the paper sheet P in the transport direction X based on the time from the timing T1 to the timing T2 (that is, the passage time) and the transport speed of the upstream adjustment transport path 11. The length calculation unit 102 outputs information indicating the calculated length to the sensor selection unit 103 and the stop conveyance control unit 104.

When the size of the paper sheet P corresponds to the medium size, the sensor selection unit 103 selects the rear end second sensor 994 as the sensor of the position detection unit 99. When the size of the paper sheet P corresponds to a large size, the sensor selection unit 103 selects the rear end third sensor 995 as the sensor of the position detection unit 99. In the embodiment, the sensor selection unit 103 selects both the first tip sensor 991 and the second tip sensor 992 as the sensors of the position detection unit 99 regardless of the size of the paper sheet P. The sensor selection unit 103 instructs the selected sensor to output the detection result to the positional deviation determination unit 105.

  The stop conveyance control unit 104 controls the first position control motor 201 or the second position control motor 202 to stop the paper sheet P at the attachment position. Based on the information indicating the timing T <b> 1 input from the length measurement sensor 98, the stop conveyance control unit 104 adjusts the conveyance speed in order to stop at the position where the leading edge of the paper sheet P coincides with the leading line Q. The first position control motor 201 or the second position control motor 202 is controlled. More specifically, the stop conveyance control unit 104 calculates the time for the leading edge of the paper sheet P to reach the leading line Q based on the conveyance speed. When it is time for the leading edge of the sheet P to reach the leading line Q, the stop conveyance control unit 104 or the first position control motor 201 or the like stops the conveyance by the first branch path 91 or the second branch path 92. The second position control motor 202 is controlled.

The position deviation determination unit 105 determines whether the amount of deviation between the position of the paper sheet P detected by the position detection unit 99 and the target position exceeds a predetermined range. When the amount of deviation exceeds the determined range, the position deviation determination unit 105 determines that the paper sheet P is displaced from the target position. The positional deviation determination unit 105 outputs the determination result to the conveyance control unit 101 and the stop conveyance control units 104 and 106. When determining that the paper sheet P is shifted from the target position, the positional deviation determination unit 105 counts the number of paper sheets P instructed to be conveyed to the exclusion box 96. When the number of paper sheets P instructed to be conveyed to the exclusion box 96 exceeds the threshold value, the positional deviation determination unit 105 causes the error output unit 120 to output an error. For example, the positional deviation determination unit 105 determines that the number of paper sheets P instructed to be conveyed to the exclusion box 96 in a predetermined unit (for example, one day, several hours, several days, several weeks, several months) exceeds a threshold value. If an error occurs, an error is output. The misalignment determination unit 105 also instructs the paper sheet P that has been instructed to be transported to the rejection box 96 after the paper sheet P is collected from the rejection box 96 (that is, when the rejection box 96 is empty). If the number exceeds the threshold, an error may be output.
The error output unit 120 may cause a predetermined display device to output an error, or may output a sound or light indicating the error. Further, the error output unit 120 may notify a predetermined display device of the content of the error (for example, the amount of the paper sheet P in the exclusion box 96 exceeds a predetermined amount).

  In the embodiment, when only a part of the sensor group arranged in the width direction Y detects the paper sheet P, the positional deviation determination unit 105 exceeds the determined range. It is determined that the paper sheet P is displaced from the target position.

  The positional deviation determination unit 105 is arranged on the downstream side in the transport direction from the sensor that detects the paper sheet P when the paper sheet P stops at the target position among the plurality of sensors included in the position detection unit 99. When the detected sensor detects the paper sheet P, it is determined that the amount of deviation exceeds the determined range and the paper sheet P is displaced from the target position.

  The positional deviation determination unit 105 determines that the combination of the sensors that detect the paper sheet P among the plurality of sensors included in the position detection unit 99 is the length of the paper sheet P calculated by the length calculation unit 102. When it matches with the combination of sensors determined accordingly, it is determined that the amount of deviation does not exceed the determined range and the sheet P is not displaced from the target position.

  The amount of deviation for determining whether or not the paper sheet P is displaced from the target position is, for example, the interval in the transport direction X between sensor groups arranged in the width direction Y, the number of sensors arranged, and the like. It can be set arbitrarily depending on the situation. If you do not want to allow a small amount of deviation, you can narrow the interval between sensors or increase the number of sensors. If a certain amount of deviation is allowed, only the minimum necessary sensors need be arranged.

  When the positional deviation determination unit 105 determines that the paper sheet P is not shifted from the target position, the label sticking control unit 106 issues a label L1 corresponding to the paper sheet P and pastes it on the paper sheet P. 97 is controlled to attach.

Next, with reference to FIG. 7, the process example by the label sticking apparatus 9 is demonstrated. FIG. 7 is a flowchart for explaining a processing example of the label sticking device 9.
The conveyance control unit 101 starts driving control of the conveyance mechanism 110 so as to convey the paper sheet P from the gap correction unit 7 in the label sticking device 9 (step ST101). The paper sheet P from the gap correction unit 7 is taken into the upstream conveyance path 90 and conveyed to the branching unit 94.

The branching unit 94 alternately distributes the paper sheets P from the upstream conveyance path 90 to the first branching path 91 or the second branching path 92 (step ST102).
For example, the branching unit 94 distributes the paper sheet P to the first branching path 91. In this case, the first branch path 91 receives the paper sheet P from the branch section 94 and transports it. Then, the paper sheet P passes through the detection position by the length measuring sensor 98. The length measuring sensor 98 detects the timing T1 when the leading edge of the paper sheet P has passed and the timing T2 when the trailing edge of the paper sheet P has passed, and calculates the length of information indicating the detected timings T1 and T2. Output to the unit 102. Further, the length measuring sensor 98 outputs information indicating the timing T <b> 1 when the leading edge of the paper sheet P passes to the stop conveyance control unit 104.

  The length calculation unit 102 calculates the length of the paper sheet P in the transport direction X based on the detection result of the length measurement sensor 98 (step ST103). The length calculation unit 102 outputs information indicating the calculated length of the paper sheet P to the sensor selection unit 103.

  The sensor selection unit 103 selects a sensor of the position detection unit 99 determined in advance according to the length of the paper sheet P based on the information indicating the length of the paper sheet P calculated by the length calculation unit 102. (Step ST104). The sensor selection unit 103 instructs the selected sensor to output the detection result to the positional deviation determination unit 105.

  The stop conveyance control unit 104 controls the first position control motor 201 to stop at the position where the leading edge of the paper sheet P coincides with the leading line Q based on the information indicating the timing T1 input from the length measurement sensor 98. (Step ST105). The first position control motor 201 controls to stop at the position where the leading edge of the paper sheet P coincides with the leading line Q by adjusting the conveyance speed of the first branch path 91 under the control from 194. . Thereby, the conveyance speed of the paper sheet P is gradually attenuated toward the leading line Q.

  Then, the stop conveyance control unit 104 conveys the paper sheet P by the distance that the leading edge of the paper sheet P reaches the leading line Q, and then sets the first position control motor 201 to stop the conveyance of the paper sheet P. Control (step ST106). Here, when the surface of the transport belt is consumed due to deterioration, the paper sheet P may move downstream in the transport direction X due to inertia, and the leading edge of the paper sheet P may exceed the leading line Q1.

  The position detection unit 99 operates the sensor selected by the sensor selection unit 103, acquires the detection result, and outputs the detection result to the position deviation determination unit 105 (step ST107).

  The position deviation determination unit 105 determines whether or not the paper sheet P is displaced from the target position based on the detection result of the position detection unit 99 (step ST108). That is, the position deviation determination unit 105 determines whether or not the amount of deviation between the position of the paper sheet P detected by the position detection unit 99 and the target position exceeds a predetermined range. When the amount of deviation exceeds the determined range, the position deviation determination unit 105 determines that the paper sheet P is displaced from the target position. The positional deviation determination unit 105 outputs the determination result to the conveyance control unit 101 and the stop conveyance control units 104 and 106.

  When it is determined that the paper sheet P is shifted from the target position (step ST108: YES), the transport control unit 101 discharges the paper sheet P to the exclusion box 96 based on the determination result of the position shift determination unit 105. The transport mechanism 110 is controlled to do so (step ST109). The stop conveyance control unit 104 controls the first position control motor 201 to convey the paper sheet P to the merge unit 95 after the determination by the position deviation determination unit 105 is completed. The first branch path 91 conveys the paper sheet P to the junction unit 95 under the control of the first position control motor 201. The junction unit 95 of the transport mechanism 110 joins the paper sheet P to the downstream side transport path 93 under the control of the transport control unit 101. The downstream conveyance path 93 of the conveyance mechanism 110 discharges the paper sheet P to the exclusion box 96 under the control of the conveyance control unit 101.

  On the other hand, if it is determined in step ST108 that the paper sheet P is not displaced from the target position (step ST108: NO), the label sticking control unit 106 determines whether the paper sheet P is based on the determination result of the position deviation determination unit 105. A label L corresponding to the leaf P is issued, and the sticking machine 97 is controlled so as to be stuck on the paper P.

The sticking machine 97 acquires print information corresponding to the paper sheet P under the control of the label sticking control unit 106, prints the acquired print information on a label tape, and issues a label L (step ST110). .
Next, the pasting machine 97 selects the negative pressure source 975, and adsorbs and holds the label L through the intake / exhaust port 974 (step ST111).
And the sticking machine 97 switches the switching valve 977, selects the ventilation source 976, and injects the label L to the paper sheet P through the intake / exhaust port 974 (step ST112). As a result, the label L is attached to the paper sheet P. After sticking the label L to the paper sheet P by the pasting machine 97, the stop conveyance control unit 104 resumes the conveyance of the paper sheet P.

  The stop conveyance control unit 104 adjusts the conveyance speed of the paper sheet P so that the conveyance gap in the downstream conveyance path 93 is within a predetermined range, and conveys the paper sheet P to the junction unit 95. The one-position control motor 201 is controlled (step ST113). The first branch path 91 conveys the paper sheet P to the junction unit 95 at an adjusted speed under the control of the first position control motor 201.

  Then, the conveyance control unit 101 controls the conveyance mechanism 110 to discharge the paper sheet P to the sorting box 8. The merge unit 95 of the conveyance mechanism 110 merges the paper sheet P into the downstream conveyance path 93 under the control of the conveyance control unit 101 (step ST114). The downstream conveyance path 93 of the conveyance mechanism 110 discharges the paper sheet P to the sorting box 8 under the control of the conveyance control unit 101.

  The sorting box 8 receives the paper sheet P from the label sticking device 9 and executes a predetermined post-process (step ST115). For example, the sorting box 8 reads information printed on the label of the paper sheet P, and conveys and stacks the paper sheet P to a storage unit corresponding to the read information.

  In parallel with the process of steps ST103 to 113, the label sticking device 9 executes steps ST116 to ST125. The processing of these steps ST116 to 125 is processing after the branching unit 94 distributes the paper sheet P to the second branching path 92 in step ST102. Therefore, the processing of steps ST116 to 125 is substantially the same as the processing of steps ST103 to 113 except that the configuration executing the processing is the second branch path 92, and thus detailed description thereof is omitted.

  Next, with reference to FIGS. 8 to 11, the positional relationship between the paper sheet P in a state stopped at the target position and each sensor of the position detection unit 99 will be described. 8 to 11 are plan views of the target position of the first branch path 91 or the second branch path 92 viewed from vertically above. In addition, the paper sheet P shown to FIGS. 8-11 is a small size.

  FIG. 8 shows a state in which the leading edge of the paper sheet P is stopped in alignment with the leading edge line Q. In this case, the leading edge first right sensor 991a, the leading edge first left sensor 991b, the trailing edge first right sensor 993a, and the trailing edge first left sensor 993b are hidden by the paper sheet P. As shown in FIG. 8, in the state of stopping at the target position, both of the front end first sensors 991 detect the paper sheet P, and the rear end first sensor is a rear end sensor corresponding to the size. Both sensors 993 detect the paper sheet P.

  FIG. 9 shows a state in which the paper sheet P has advanced downstream in the transport direction X due to inertia, and the leading edge of the paper sheet P has stopped downstream of the leading edge line Q. In this case, the leading edge first right sensor 991a, the leading edge first left sensor 991b, the leading edge second right sensor 992a, and the leading edge second left sensor 992b are hidden by the paper sheet P. As shown in FIG. 9, both the sensors at the rear end first sensor 993 have not detected the paper sheet P in a state where it is stopped at a position shifted from the target position. The leading edge second sensor 992 on the downstream side of the leading line Q detects the paper sheet P.

  FIG. 10 shows a state in which the paper sheet P rotates due to inertia and stops at a position where the leading edge of the paper sheet P and the leading edge line Q are not parallel. In this case, the leading edge first right sensor 991a, the leading edge second right sensor 992a, and the leading edge second left sensor 992b are hidden by the paper sheet P. As shown in FIG. 10, one of the leading end first sensors 991 does not detect the paper sheet P in a state where it stops at a position shifted from the target position.

  In FIG. 11, the paper sheet P advances downstream in the transport direction X while rotating due to inertia, and the leading edge of the paper sheet P is downstream from the leading edge line Q, and the leading edge of the paper sheet P The state which has stopped in the position where the front end line Q is not parallel is shown. In this case, the leading edge first right sensor 991a, the leading edge first left sensor 991b, the leading edge second right sensor 992a, and the trailing edge first left sensor 993b are hidden by the paper sheet P. As shown in FIG. 11, one sensor of the rear end first sensor 993 does not detect the paper sheet P in a state where it stops at a position shifted from the target position. The leading edge second sensor 992 on the downstream side of the leading line Q detects the paper sheet P.

  Next, with reference to FIG. 12, an example of a process for determining the displacement of the target position will be described. FIG. 12 is a flowchart for explaining a processing example of the position deviation determination of the target position.

  The positional deviation determination unit 105 determines whether only some of the sensors arranged in the width direction Y have detected the paper sheet P based on the detection result of the first tip sensor 991 ( Step ST201). That is, the positional deviation determination unit 105 determines whether only some of the leading edge first right sensor 991a and leading edge first left sensor 991b have detected the paper sheet P. When both the leading edge first right sensor 991a and the leading edge first left sensor 991b detect the paper sheet P, the positional deviation determination unit 105 determines that only a part of the sensors arranged in the width direction Y is the sensor. It is determined that the paper sheet P is not detected.

  When it is determined that both the leading edge first right sensor 991a and the leading edge first left sensor 991b have detected the paper sheet P (step ST201: YES), the positional deviation determination unit 105 determines according to the size of the paper sheet P. Based on the detection result of the rear end detection unit (any one of the rear end first sensor 993, the rear end second sensor 994, and the rear end third sensor 995), it is arranged in the width direction Y. It is determined whether only some sensors in the sensor group have detected the paper sheet P (step ST202). For example, when the paper sheet P is a small size, the positional deviation determination unit 105 detects the paper sheet P only in some of the rear end first right sensor 993a and the rear end first left sensor 993b. Determine whether or not. When both the rear end first right sensor 993a and the rear end first left sensor 993b detect the paper sheet P, the positional deviation determination unit 105 selects some of the sensors in the sensor group arranged in the width direction Y. Only the paper sheet P is determined not to be detected.

  For example, when it is determined that both the rear end first right sensor 993a and the rear end first left sensor 993b have detected the sheet P (step ST202: YES), the positional deviation determination unit 105 determines whether the front end second sensor 992 Based on the detection result, among the plurality of sensors included in the position detection unit 99, when the paper sheet P stops at the target position, the sensor is disposed downstream of the sensor that detects the paper sheet P. It is determined whether or not the sensor has detected the paper sheet P (step ST203). That is, the positional deviation determination unit 105 determines whether or not at least one of the leading edge second right sensor 992a and the leading edge second left sensor 992b has detected the paper sheet P. When at least one of the leading edge second right sensor 992a and the leading edge second left sensor 992b does not detect the paper sheet P, the positional deviation determination unit 105 determines whether the paper sheet P stops when the paper sheet P stops at the target position. It is not determined that the sensor arranged on the downstream side in the transport direction with respect to the sensor that detects the paper sheet P has been detected.

  When it is not determined that at least one of the leading edge second right sensor 992a and the leading edge second left sensor 992b has detected the sheet P (step ST203: NO), the positional deviation determination unit 105 is detected by the position detection unit 99. It is determined that the amount of deviation between the position of the paper sheet P and the target position does not exceed the determined range (step ST204).

On the other hand, when the leading edge first right sensor 991a or leading edge first left sensor 991b does not detect the paper sheet P in step ST201 (step ST201: NO), the positional deviation determination unit 105 is detected by the position detection unit 99. It is determined that the amount of deviation between the position of the paper sheet P and the target position exceeds the determined range (step ST205). This is a determination result in the state shown in FIG.
In step ST202, when the rear end first right sensor 993a or the rear end first left sensor 993b does not detect the paper sheet P (step ST202: NO), the position deviation determination unit 105 is detected by the position detection unit 99. It is determined that the amount of deviation between the position of the paper sheet P and the target position exceeds the determined range (step ST205). This is a determination result in the state shown in FIGS.
In Step ST203, when it is determined that at least one of the leading edge second right sensor 992a and the leading edge second left sensor 992b has detected the sheet P (Step ST203: YES), the positional deviation determination unit 105 determines whether the It is determined that the amount of deviation between the position of the paper sheet P detected by the detection unit 99 and the target position exceeds the determined range (step ST205). This is a determination result in the state shown in FIGS.

  In the above embodiment, the positional deviation determination unit 105 can determine the positional deviation between the position of the paper sheet P and the target position by combining the determinations of steps ST201, 202, and 203. For example, the determination may be made using only at least one of steps ST201, 202, and 203.

  In the above embodiment, the front end first sensor 991, the front end second sensor 992, the rear end first sensor 993, the rear end second sensor 994, and the rear end third sensor 995 are arranged in the width direction Y. However, the present invention is not limited to this. For example, a sensor group in which three or more sensors are arranged in the width direction Y may be used.

  In the above embodiment, the leading edge first sensor 991, the leading edge second sensor 992, the trailing edge first sensor 993, the trailing edge second sensor 994, and the trailing edge third sensor 995 are paper sheets based on the leading line Q. A sensor for detecting the front end or the rear end of P is determined in advance, but is not limited thereto. For example, it may be a sensor that detects the leading edge or the trailing edge of the paper sheet P with reference to the trailing edge of the paper sheet P.

  In the above-described embodiment, the leading edge first sensor 991, the leading edge second sensor 992, the trailing edge first sensor 993, the trailing edge second sensor 994, and the trailing edge third sensor 995 are located anywhere on the paper sheet P. Although it is determined whether it is a sensor to detect, it is not restricted to this. For example, the positional deviation determination unit 105 may determine the positional deviation according to a combination of sensors determined according to the size of the paper sheet P. That is, when the label attaching position differs in the transport direction X according to the paper sheet P, the combination of the sensors that detect the paper sheet P matches the sensor combination determined according to the size of the paper sheet P. If there is, the position deviation determination unit 105 can determine that there is no position deviation.

  In the above embodiment, the positional deviation determination unit 105 may change the leading line Q according to the size of the paper sheet P. In this case, the positional deviation determination unit 105 determines the positional deviation based on the label attachment position corresponding to the reference and the detected position of the paper sheet P with the leading position corresponding to the size of the paper sheet P as a reference. .

  In the above embodiment, a sensor for detecting the amount of the paper sheet P accommodated in the exclusion box 96 is mounted on the exclusion box 96, and the CPU 100 detects that the amount of the paper sheet P detected by the sensor exceeds a predetermined amount. In such a case, an error may be output from the error output unit 120. For example, when the height or weight of the paper sheet P exceeds a threshold based on the detection result of the sensor that detects the height or weight of the paper sheet P stacked and accommodated in the exclusion box 96, the CPU 100 An error is output from the error output unit 120.

  In the above embodiment, the sensor selection unit 103 may be omitted. In this case, the positional deviation determination unit 105 determines the positional deviation based on the detection results of the tip first sensor 991 and the tip second sensor 992.

  In the above embodiment, the number of position detection units 99 is not limited to this. For example, line sensors may be provided on both sides of 122c, and it may be determined whether or not the stopped paper sheet P is displaced from the target position. By using the line sensor, it is possible to detect the detailed position of the paper sheet P in a stopped state. Therefore, it is possible to improve the positional deviation detection accuracy.

  In the said embodiment, the exclusion box 96 is not restricted to the structure mounted in the label sticking apparatus 9. FIG. For example, the exclusion box 96 may be provided in the sorting box 8. In this case, the label sticking device 9 conveys the paper sheet P determined that the stop position is deviated from the target position to the sorting box 8.

  In the above embodiment, the label sticking device 9 may detect or correct deterioration due to aging of the transport belt based on the result of the position detection unit 99 or the determination result of the position deviation determination unit 105. For example, the CPU 100 may include a detection unit that detects deterioration due to aging of the transport belt when the number of times that the stop position of the paper sheet P is determined to be shifted from the target position is greater than a threshold value. Further, the label sticking device 9 is a mechanism that adjusts the pressure of the support portion so as to increase the tension of the conveyor belt when the number of times that the stop position of the paper sheet P is determined to be shifted from the target position is greater than the threshold value. May be provided.

  According to at least one embodiment described above, when it is determined that the amount of deviation between the position of the paper sheet P and the target position exceeds a predetermined range, the paper sheet P is discharged into the exclusion box 96. By having the conveyance control unit 101 that controls the labeling, it is possible to prevent the label from being attached to a position shifted from the label target position of the paper sheet P. As a result, the work of removing the label and attaching it again does not occur, and the work burden on the operator can be reduced.

  In addition, the pasting unit 972 applies a label to the stopped paper sheet P only when it is determined that the amount of deviation between the position of the paper sheet P and the target position does not exceed the determined range. paste. With this configuration, it is possible to prevent the label from being attached to a position shifted from the label target position of the paper sheet P.

  Further, the positional deviation determination unit 105 exceeds the range in which the deviation amount is determined when only some of the sensors arranged in the width direction Y of the position detection unit 99 detect the paper sheet P. It is determined that With this configuration, the deviation in the width direction Y of the posture of the paper sheet P can be detected with a simple configuration.

  The positional deviation determination unit 105 is further downstream in the transport direction than the sensor that detects the paper sheet P when the paper sheet P stops at the target position among the plurality of sensors included in the position detection unit 99. When the leading edge second sensor 992 (the leading edge second right sensor 992a and the leading edge second left sensor 992b), which is a sensor disposed on the paper sheet, detects the paper sheet P, it is determined that the amount of deviation exceeds the determined range. To do. With this configuration, the deviation of the posture of the paper sheet P in the transport direction X can be detected with a simple configuration.

  In addition, the positional deviation determination unit 105 determines the length of the sheet P calculated by the length calculation unit 102 from the combination of the sensors that have detected the sheet P among the plurality of sensors included in the position detection unit 99. When the sensor combination is determined according to the above, it is determined that the deviation amount does not exceed the determined range. With this configuration, both the deviation in the conveyance direction X and the deviation in the width direction Y of the posture of the paper sheet P can be detected more accurately.

  In addition, the label sticking control unit 106 determines that the amount of deviation between the position of the paper sheet P and the target position does not exceed the determined range, and information corresponding to the stopped paper sheet P. Is printed on the label sheet, and the issuing unit 971 is controlled to issue the label L. With this configuration, it is possible to prevent the label L from being issued to the paper sheet P that is determined not to be attached due to the positional deviation.

  The transport mechanism 110 is configured to transport the paper sheet P between the transport belts. With this configuration, compared to a configuration in which both ends of the paper sheet P are clamped by the clamping means when the paper sheet P is stopped, the surface of the paper sheet P can be less damaged, and the positional deviation when the paper sheet P is stopped can be reduced.

  Although the label pasting device 9 of each of the above embodiments has been described with respect to a case where a function (program) for carrying out the present embodiment is set in advance in the device, the same function (program) is not limited to this, but is connected to the network. May be downloaded to the apparatus, or a similar function (program) stored in a recording medium may be installed in the apparatus. The recording medium may take any form as long as it can store a program such as an optical disk and a USB memory and can be read by the apparatus. Further, the function obtained by installing or downloading in advance may be realized in cooperation with an OS (operating system) or the like inside the apparatus.
