In the midst of being transported, it is brought into contact with the upper surface of the bottom 31 of the stacking unit 30 in a standing position. Then, further lowering of the paper sheet S is restricted, and the paper sheet S is drawn out between the adjacent blades 33 of the rotating accumulation delivery vehicle 25 (that is, discharged from the conveyance unit 22 to the accumulation unit 30) and held until then. The blades 33 are pushed forward by the blades 33 on the upstream side in the rotational direction. As a result, the lower end edge of the paper sheet S is guided by the upper surface of the bottom 31 of the stacking unit 30 and moves forward in the standing position, and is received by the receiving wall 32 of the stacking unit 30. Therefore, the stacking unit 30 receives the sheets S discharged from the transport unit 22 by the front receiving wall 32 and stacks them in the front-rear direction in the standing position.

In the state where 65b receives light, it is detected that there is no paper S in the space between them, that is, the stacking unit 30, and in the state where the light emitted by the light emitting element 65a is not received It detects that there is a sheet S.

  As shown in FIG. 2, in the stacking unit 30, the center portion in the left-right direction of the bottom portion 31 of the stacking unit 30 is configured by an insole configuration portion 71 integral with the guide portion 26. The stacking portion 30 has a slide member 72 which can slide in the front-rear direction with respect to the insole configuration portion 71. Assuming that the portion excluding the slide member 72 of the paper sheet counter 1 is the counter main body 101, the insole construction section 71 is provided in the counter main body 101. In the counter main body 101, side walls 102 are formed on the left and right sides of the guide 26 so as to project forward of the guide 26. The side wall portion 102 on both sides is formed with a protruding portion 104 protruding forward in the upper part than the middle portion 103 in the vertical direction, and an extending portion 105 extending in the lower part further than the middle portion 103 and the protruding portion 104. Is formed. A slide member 72 is disposed between the extension parts 105 on both sides.

  As shown in FIG. 4, the slide member 72 includes left and right side bottom components 75 that form the bottom 31 on both sides of the insole component 71 and side bottom components 75 on both sides of the insole component 71. And the receiving wall 32 extending upward from the front end edge of the side bottom component 75 on both sides, and the middle bottom component 71 of each side bottom component 75 opposite to each other. Integrally with both side wall portions 77 extending upward from the side edge. A guide groove 81 is formed in a pair on the left and right in the connecting portion 76, and the slide member 72 is in the middle bottom portion by a pair of left and right guide pins 82 inserted into the guide grooves 81 and fixed to the middle bottom portion 71. It is linked to 71. As shown in FIG. 5, the guide groove 81 has a long shape in the front-rear direction, and the guide pin 82 is movable relative to the guide groove 81 in the front-rear direction. As a result, the slide member 72 is slidably coupled to the insole construction portion 71 of the counter main body 101.

  The slide member 72 is determined by the guide groove 81 as shown in FIGS. 5 (a) and 5 (b) while maintaining the upper surfaces of the side bottom components 75 on both sides in the same plane as the upper surface of the middle bottom component 71. It can slide back and forth by a predetermined range. That is, as shown in FIG. 5A, the rear end position for bringing the guide pin 82 into contact with the front end of the guide groove 81, and as shown in FIG. 5B, the guide pin 82 at the rear end of the guide groove 81. It is slidable in the range between the front end position where it abuts.

  The slide member 72 is manually guided by the extension portions 105 on both sides of the counter main body 101 shown in FIG. 2, the insole construction portion 71 shown in FIG. 4 and the left and right guide pins 82 shown in FIGS. While sliding in the back and forth direction. When the manual operation is released, the slide member 72 is adapted to maintain the stopped state at an arbitrary position mainly by the frictional force between the extension portion 105 on the both sides and the insole construction portion 71.

  As shown in FIG. 4, a detection target portion 84 protruding outward in the left-right direction is integrally provided on one wall portion 77 side of the slide member 72. The detected portion 84 has a shape extending in the sliding direction of the slide member 72 as shown in FIG. As shown in FIG. 4, in the side wall portion 102 of the counter main body 101 on the same side in the left-right direction as the detected portion 84, a plurality of the four position detection sensors shown in FIG. There are 85, 86, 87 and 88 arranged in this order from the rear to the front.

  The position detection sensor 85 is an optical sensor composed of a light emitting element 85a and a light receiving element 85b, and in a state where the light emitting element 85b receives light emitted by the light emitting element 85a, there is no detected portion 84 between them. In the state where the light receiving element 85b does not receive the light emitted from the light emitting element 85a, it is detected that the to-be-detected portion 84 is present between them. Similarly, in the position detection sensors 86 to 88, the position detection sensor 86 is a light emitting element 86a and a light receiving element 86b, the position detection sensor 87 is a light emitting element 87a and a light receiving element 87b, and the position detection sensor 88 is a light emitting element 88a and a light receiving element 88b. Each one.

  The rearmost position detection sensor 85 is located at the rear end position where the slide member 72 including the receiving wall 32 is pushed backward most with respect to the counter main body 101 as shown in FIG. 6A. It is provided at a position where the detected portion 84 is detected. The position detection sensor 88 located at the frontmost position is the detected portion when the slide member 72 including the receiving wall 32 is positioned at the front end position most drawn out with respect to the counter main body 101 as shown in FIG. It is provided in the position which does not detect 84. The position detection sensors 85 to 88 detect that the slide member 72 including the receiving wall 32 is positioned on the front side as the number of detection of the detection target portion 84 is small. In other words, the position detection sensors 85 to 88 detect that the slide member 72 including the receiving wall 32 is positioned rearward as the number of the detection target portions 84 is increased.

  The plurality of position detection sensors 85 to 88 arranged in the front and rear direction constitute a position detection unit 90 that detects the stop position of the slide member 72 including the receiving wall 32 in the front-rear direction. Here, the discharge / residue detection sensor 65 shown in FIG. 1 detects the presence or absence of the sheet S of the stacking unit 30 regardless of the position of the slide member 72 in the front-rear direction.

  As shown in FIG. 2, an operation unit 110 and a display unit 111 are provided on the upper front of the counter main body 101 of the paper sheet counter 1. Further, a storage unit 115 and a control unit 116 (stacked thickness detection means, control means, clear means) shown in FIG. 3 are provided inside the counter main body 101.

  Here, the control unit 116 can select and set the identification item of the identification and counting unit 41 in advance by the operation input to the operation unit 110. For example, in the case of counting banknotes as the sheet S, the identification / counting unit 41 discriminates authenticity, correctness and normality of the denomination, and as the sheet S, a sheet of a prescribed size such as a voting sheet In the case of counting, it is possible to identify the normal abnormality of the transport direction length.

  In the paper counter 1 described above, when the operator sets the paper sheets to be counted in the hopper 11 of the paper counter 1 in a stacked state and the start operation is input to the start button of the operation unit 110 , Control unit 116 starts counting processing. At the start of the counting process, the control unit 116 first determines the detection state of the detection target unit 84 of the position detection sensors 85 to 88 of the position detection unit 90. Then, a fullness determination thickness Tm, which is a fullness determination amount of accumulation of the paper sheets S of the accumulation unit 30, is determined according to the detection state of the detected portion 84 of the position detection sensors 85 to 88. Specifically, the fullness determination thickness Tm of the accumulation of the accumulation unit 30 stored for each of the detection states of the detection target units 84 of the position detection sensors 85 to 88 is read from the storage unit 115. The full determination thickness Tm of the accumulation is an allowable maximum value of the accumulation thickness of the sheets S accumulated in the accumulation unit 30.

  That is, as shown in FIG. 6A, the storage unit 115 includes the first fullness determination thickness Tm1 in the case where all the position detection sensors 85 to 88 detect the detected portion 84, and the rear end The second fullness determination thickness Tm2 when the position detection sensor 85 does not detect the detected portion 84 and all the position detection sensors 86 to 88 on the front side detect the detected portion 84 is set in advance. It is memorized. In the storage unit 115, the two position detection sensors 85 and 86 do not detect the detected portion 84 from the rear end, and the position detection sensors 87 and 88 on the front side detect the detected portion 84. When the third fullness detection thickness Tm3 and the three position detection sensors 85 to 87 do not detect the detected portion 84 from the rear end, and only the frontmost position detection sensor 88 detects the detected portion 84 A fourth fullness determination thickness Tm4, and a fifth fullness determination thickness Tm5 when all the position detection sensors 85 to 88 do not detect the detected portion 84 as shown in FIG. Are set and stored in advance.

  Here, the first to fifth fullness determination thicknesses Tm1 to Tm5 are maximum values in a range in which the jam occurrence rate of the paper sheet S becomes lower than a predetermined ratio in the stacking unit 30, and simulation or experiment is performed in advance. It is set in. Therefore, the second fullness determination thickness Tm2 is larger than the first fullness determination thickness Tm1, and the third fullness determination thickness Tm3 is larger than the second fullness determination thickness Tm2, the third The fourth fullness determination thickness Tm4 is larger than the fullness determination thickness Tm3 and the fifth fullness determination thickness Tm5 is larger than the fourth fullness determination thickness Tm4.

  If all of the position detection sensors 85 to 88 have detected the detected portion 84 in the determination of the detection state of the detected portion 84 by the position detection unit 90 described above, the control unit 116 calculates the first fullness determination thickness Tm1. Is read from the storage unit 115, and the first fullness determination thickness Tm1 is set to the fullness determination thickness. That is, the first full determination thickness Tm1 is indexed as the full determination thickness. In addition, if only the position detection sensors 86 to 88 detect the detection target unit 84, the control unit 116 reads the second fullness determination thickness Tm2 from the storage unit 115 and sets the second fullness determination thickness Tm2 as the fullness determination thickness. In addition, if only the position detection sensors 87 and 88 detect the detection target 84, the control unit 116 reads the third fullness determination thickness Tm3 from the storage unit 115, and sets the third fullness determination thickness Tm3 as the fullness determination thickness. If only the position detection sensor 88 detects the detected portion 84, the control unit 116 reads the fourth fullness determination thickness Tm4 from the storage unit 115 and sets the fourth fullness determination thickness as the fullness determination thickness. If none of the position detection sensors 85 to 88 detects the detected portion 84, the control unit 116 reads the fifth fullness determination thickness Tm5 from the storage unit 115, and sets it as the fullness determination thickness. .

  As described above, the control unit 116 and the storage unit 115 determine the fullness determination amount of the accumulation of the accumulation unit 30 based on the detection result of the position detection unit 90 including the position detection sensors 85 to 88. At that time, the accumulation thickness of the sheets S accumulated in the accumulation unit 30 is determined as a fullness determination amount, that is, a fullness determination thickness.

  Next, the control unit 116 sets the rotation speed of the counting motor 15 to a predetermined counting rotation speed which is set in advance and stored in the storage unit 115, and the rotation speed of the accumulation discharge car motor 27 is set in advance. It drives as a predetermined accumulation delivery vehicle rotational speed stored in the storage unit 115. Then, the transport roller 24 and the accumulation delivery vehicle 25 rotate. Next, the control unit 116 connects the clutch 16. Then, the kicking roller 12 and the feeding roller 13 rotate together, and the sheets S in the sheet group loaded and placed in the hopper 11 are separated one by one and sequentially delivered to the transport unit 22. The sheet S sent to the conveyance unit 22 is conveyed toward the stacking unit 30 by the conveyance roller 24. At that time, the identification and counting unit 41 performs identification and counting, and the thickness detection unit 51 After the thickness detection is performed, the sheet is fed to the accumulation discharge vehicle 25 and discharged from the accumulation discharge wheel 25 to the accumulation unit 30. At that time, the paper sheet S is pushed forward in the standing position, moves on the bottom portion 31 of the stacking unit 30 and is put on the receiving wall 32 so as to be sequentially stacked from front to back.

  After the start operation is input to the start button of the operation unit 110, the control unit 116 sequentially accumulates the thickness t of the sheet S detected by the thickness detection unit 51 to calculate and store the cumulative value akak. There is. For example, after the start operation is input, five sheets S are detected by the counting sensor 42, and the thickness t detected by the thickness detection unit 51 of these sheets S is t1, t2, t3, t4, and t5. If there is, the cumulative value akak = t1 + t2 + t3 + t4 + t5 is calculated and stored. The accumulated value akak is an accumulated thickness which is the accumulated amount of the sheets S of the accumulation unit 30 when the sheet S having the thickness t finally added to the accumulated value akak is discharged to the accumulation unit 30. It becomes T. That is, the control unit 116 detects the accumulation thickness T of the sheets S of the accumulation unit 30 from the accumulated value akak of the thickness t of the sheet S detected by the thickness detection unit 51.

  Then, the control unit 116 sets the accumulated value 満 ak of the thickness t of the paper sheet S detected by the thickness detection unit 51 according to the position of the slide member 72 including the receiving wall 32 described above. When the determination thickness Tm is reached (that is, akak Tm Tm), the sheet S having the thickness t finally added to the accumulated value akak is discharged to the accumulation unit 30, that is, the sheet S of the accumulation unit 30 When the accumulated thickness T, which is the accumulated amount of paper, reaches the above-mentioned full judgment thickness Tm, the delivery of the paper sheet S by the delivery unit 21, the conveyance of the paper sheet S by the conveyance unit 22, and the paper to the accumulation unit 30 The discharge of the leaves S is temporarily stopped to interrupt the counting process.

  Specifically, when the control unit 116 reaches the fullness determination thickness Tm at which the cumulative value akak is set, the sheet S in which the thickness t is finally added to the cumulative value akak is discharged to the stacking unit 30. At this time, the counting motor 15 is stopped, and the clutch 16 is brought into the non-connected state, and the feeding roller 13 and the kicking roller 12 are stopped by the brake 17. Further, the control unit 116 stops the accumulation discharge vehicle motor 27 simultaneously with the stop of the counting motor 15. By stopping the counting motor 15 and the accumulation discharge car motor 27, the conveyance roller 24 and the accumulation discharge car 25 also stop, and the next sheet S of the sheet S, the thickness t of which is finally added to the accumulated value akak Although they remain in the transport unit 22, they are not discharged into the stacking unit 30.

  In addition, if the interval of feeding of the paper sheet S of the feeding unit 21 is set to feed the next sheet S when the fed one sheet S is discharged to the stacking unit 30, the feeding unit When the delivery of the paper sheet S is stopped, basically, the paper sheet S does not remain in the transport unit 22. In this case, if the feeding of the sheet S by the feeding unit 21 is once stopped, the conveyance and discharge of the sheet S can be stopped even if the conveyance unit 22 on the downstream side maintains the driving state. Therefore, the control unit 116 brings the clutch 16 into the non-connected state without stopping the counting motor 15 and the accumulation discharge motor 27 and the feeding roller 13 and the kicking roller 12 are stopped by the brake 17. The feeding of the sheet S by the sheet feeding and the conveyance of the sheet S to the stacking unit 30 by the conveyance unit 22 are stopped. Of course, in the case of such an interval of delivery of the paper sheet S, the counting motor 15 and the accumulation delivery car motor 27 may be stopped.

  Specifically, if all the position detection sensors 85 to 88 have detected the detection target unit 84, the control unit 116 determines that the accumulation thickness T of the sheets S of the accumulation unit 30 is the first full determination thickness Tm1. When it reaches, the feeding of the sheet S by the feeding unit 21 and the conveyance of the sheet S by the conveyance unit 22 are temporarily stopped. In addition, if only position detection sensors 86 to 88 have detected detected portion 84, when the stacking thickness of sheets S of stacking portion 30 reaches the second full judgment thickness Tm2, the paper by feeding portion 21 The delivery of the leaf S and the transport of the sheet S by the transport unit 22 are temporarily stopped. In addition, if only position detection sensors 87 and 88 have detected detected portion 84, when stacking thickness T of sheets S of stacking portion 30 reaches third full determination thickness Tm3, feeding portion 21 The feeding of the sheet S and the conveyance of the sheet S by the conveyance unit 22 are temporarily stopped. In addition, if only position detection sensor 88 detects detected portion 84, if the stacking thickness T of the paper sheet S of stacking portion 30 becomes the fourth full determination thickness Tm4, the paper sheet S by feeding portion 21 Delivery of the sheet S by the delivery unit 22 is temporarily stopped. Further, if none of the position detection sensors 85 to 88 detects the detected portion 84, when the accumulated thickness T of the sheets S of the accumulating portion 30 becomes the fifth full determination thickness Tm5, the feeding portion 21 The feeding of the sheet S and the conveyance of the sheet S by the conveyance unit 22 are temporarily stopped.

  From the state in which the conveyance of the paper sheet S by the conveyance unit 22 and the discharge of the paper sheet S to the accumulation unit 30 by the conveyance unit 22 are temporarily stopped as described above, the paper sheet S of the accumulation unit 30 has a paper sheet to no paper sheet When the discharge / residue detection sensor 65 detects that it is in the state, the control unit 116 clears the accumulated value akak which is the accumulated amount of the paper sheets S of the accumulation unit 30, that is, the accumulated thickness T to 0. And, while driving the collecting discharge motor 27 and releasing the brake 17 to bring the clutch 16 into a connected state, the delivery of the sheet S by the feeding unit 21 and the conveyance and discharge of the sheet S by the conveyance unit 22 are resumed. . That is, the counting process is resumed.

  The above is repeated appropriately, and when the insertion detection sensor 18, the identification / counting unit 41 and the conveyance residual detection sensor 61 detect that the hopper 11 and the conveyance unit 22 do not have the sheet S, the control unit 116 controls the counting motor 15 and the accumulation. The delivery vehicle motor 27 is stopped, the clutch 16 is in the non-connected state, the brake 17 is applied, the delivery of the paper sheet S by the delivery unit 21 and the conveyance of the paper sheet S by the conveyance unit 22 are stopped. The accumulated value akak, which is the accumulated amount of the leaves S, ie, the accumulated thickness T, is cleared to 0, the counting result of the identification counting unit 41 is displayed on the display unit 111, and the current counting process is ended.

  Of course, after the start of the counting process, the accumulated value akak of the thickness t of the paper sheet S detected by the thickness detection unit 51 is the fullness determination thickness indexed according to the position of the slide member 72 including the receiving wall 32 Even when the insertion detection sensor 18, the identification / counting unit 41, and the conveyance residual detection sensor 61 detect that the hopper 11 and the conveyance unit 22 have no paper sheet S without reaching Tm, the control unit 116 Do the same control. That is, the control unit 116 stops the delivery of the paper sheet S by the delivery unit 21 and stops the conveyance of the paper sheet S by the conveyance unit 22 and also the accumulated value akak which is the accumulation amount of the paper sheet S of the accumulation unit 30. T is cleared to 0, the counting result of the identification counting unit 41 is displayed on the display unit 111, and the counting process is ended.

  In the above, the near-full determination thickness Tn smaller than the full determination thickness Tm is set according to the position of the slide member 72 including the receiving wall 32, and the accumulation value akak, that is, the accumulation of the paper sheets S of the accumulation unit 30. When the thickness T reaches the near full judgment thickness Tn, the speed of feeding of the paper sheet S by the feeding unit 21 and the speed of conveyance of the paper sheet S by the conveyance unit 22 may be lowered to perform intermittent feeding. As a result, it is possible to notify the operator that it is almost full.

  According to the present embodiment described above, the stacking unit 30 is configured such that the paper sheets S discharged from the transport unit 22 can be stacked in the front-rear direction in the standing position by receiving the paper sheet S in the front receiving wall 32 and taken out outside the machine. And the receiving wall 32 can slide in the front-rear direction. Therefore, if downsizing of the airframe is desired, the receiving wall 32 constituting the front of the airframe can be downsized by positioning the receiving wall 32 at the rear position, and an increase in the accumulation amount of the stacking unit 30 is desired. Can be increased by positioning the receiving wall 32 in the forward position.

  Further, when the position detection unit 90 detects the stop position in the front-rear direction of the receiving wall 32, the control unit 116 determines the fullness determination amount of accumulation of the accumulation unit 30 from the information stored in the storage unit 115 based on this. Then, when the accumulation amount of the sheets S of the accumulation unit 30 detected based on the detection result of the thickness detection unit 51 reaches the full determination amount, the control unit 116 delivers and conveys the sheet S by the delivery unit 21. The conveyance of the paper sheet S to the stacking unit 30 by 22 is stopped. Therefore, even if the receiving wall 32 is slidable in the front-rear direction, it is possible to cause the stacking unit 30 to stack the stacked sheets S according to the stop position of the receiving wall 32. Therefore, regardless of the stopping position of the receiving wall 32, occurrence of jamming caused when the accumulated amount is too large can be suppressed, and decrease in counting efficiency caused when the accumulated amount is too small can be suppressed.

  Further, when the thickness detection unit 51 detects the thickness of the paper sheet S being moved by the conveyance unit 22, the control unit 116 accumulates the accumulated value of the thickness of the paper sheet S detected by the thickness detection unit 51. When the accumulated amount reaches the fullness determination amount, the delivery of the paper sheet S by the delivery unit 21 and the conveyance of the paper sheet S to the accumulation unit 30 by the conveyance unit 22 are stopped. Therefore, when counting a plurality of types of sheets S having different thicknesses, occurrence of jam can be suppressed even when counting thick sheets S, and counting even when counting thin sheets S. It is possible to suppress the decrease in efficiency.

  According to the embodiment described above, when the thickness detection unit 51 detects the thickness of the sheet S being moved by the conveyance unit 22, the control unit 116 detects the thickness of the sheet S detected by the thickness detection unit 51. The accumulated thickness of the sheets S of the accumulation unit 30 is detected from the accumulated value of the thickness of the sheet. Therefore, when processing a plurality of types of sheets S having different thicknesses, it is possible to detect the accumulated thickness of the sheets S.

  In addition, when the stacking thickness of the sheets S of the stacking unit 30 detected by the thickness detection unit 51 reaches the full determination thickness, the control unit 116 causes the transport unit 22 to transport the sheet S to the stacking unit 30. Stop it. Therefore, it is possible to suppress the occurrence of jamming that occurs as the accumulation thickness becomes thick, and to suppress the decrease in processing efficiency that occurs when the accumulation thickness is thin and stop.

  In addition, when the discharge / residence detection sensor 65 for detecting the presence or absence of the sheet S of the stacking unit 30 detects that there is no sheet from the presence of the sheet, the control unit 116 clears the stacking thickness of the stacking unit 30 up to that point. It is possible to automatically resume the process. Therefore, the decrease in processing efficiency can be suppressed.

  In the above embodiment, the slide member 72 is manually operated to slide back and forth. However, the slide member 72 may be driven to slide by a motor. In that case, it is possible to detect the stop position of the slide member 72 by the amount of rotation of the motor.

  In the above embodiment, the sheet counting machine 1 for counting the sheets S has been described as an example. However, the sheet processing machine may have a portion in which the sheets are conveyed one by one and accumulated in the accumulation unit. For example, the present invention is applicable to various other sheet processing machines.
