Japanese Patent No. 4130697

  The paper sheet transport technology disclosed in Patent Document 1 forms a deformed portion (bent or curved portion) at the rear end of the paper sheet in the transport direction, and applies wind pressure to the deformed portion. As a result, the paper sheet obtains a propulsive force, and the paper sheet is conveyed so as to flow in the blower pipe in a state where the deformed portion is formed. When the paper is collected in the collection device at the transport destination, the paper sheet and the air flow are separated by the separation unit, and the paper sheet is stored in the storage unit in a state where the deformed part is corrected and flattened by the correction unit. Stored. However, before being conveyed from the separation unit to the correction unit, the paper sheets may be separated from the air flow and stay in the separation unit.

  13 is a top view showing a part of the separation part 150 examined by the present inventor in a transparent state, and FIG. 14 shows a part of the separation part 150 attached to the terminal part of the blower tube 10 in a transparent state. It is a top view. A conveyor belt 151 is stretched from the blower tube 10 side to the separation unit 150. A conveying belt 151 and a squeegee 155 attached to the guide plate 156 are arranged so that the paper sheets conveyed in the x direction (conveying direction) in the blower tube 10 are gradually narrowed in a V shape. After receiving the paper sheet conveyed by the V-shaped opening (passage) formed by these, it is squeezed by the drive pulley 152 and the roller 154 and sent out to the correction section.

  The conveyor belt 151 is an endless belt, and is stretched around the drive pulley 152 and the passive pulley 153. Here, the conveyance force of the conveyance belt 151 increases as the belt length increases. For example, the ability to convey a plurality of sheets is higher than the ability to convey one sheet.

  Therefore, in the conveyor belt 151 studied by the present inventor, when an attempt is made to lengthen the belt length in order to increase the conveying force, the conveyor belt 151 forms a V-shaped opening and therefore spreads outward. In order to store the conveyor belt 151 in the separation unit 150, it is necessary to change the design to increase the width (size) of the separation unit 150. This design change of the separating unit 150 leads to a review of the design of the entire paper sheet transporting device such as the blower tube 10 connected to the separating unit 150, and it takes time to start up (operate) the paper sheet transporting device. .

  On the other hand, when such a design change is not performed, the belt length of the conveyor belt 151 becomes insufficient, so that the conveying force is insufficient and the paper sheets are likely to stay. In particular, when a plurality of sheets are stacked, it becomes difficult to convey and the number of staying sheets increases, resulting in a vicious cycle, and it is necessary to stop the operation of the sheet conveying apparatus and restore it by work.

  The objective of this invention is providing the technique which can improve the operation rate of the paper sheet conveying apparatus which conveys paper sheets by an air flow. The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiments, and the repetitive description thereof may be omitted.

  First, the overall configuration of the paper sheet transport apparatus 1 in the present embodiment will be described with reference to FIG. In addition, about this paper sheet conveying apparatus 1, the technique of patent document 1 which this inventor proposed can also be referred.

  The paper sheet transport device 1 includes a blower tube 10, a feeding device 20 that forms a deformed portion 2 b at the rear end of the paper sheet 2 and feeds the paper sheet 2 into the blower tube 10, and a paper sheet 2. An air flow generating device 30 that causes wind pressure to act on the deforming portion 2b to cause the paper sheet 2 to generate an air flow in the blower tube 10 and a terminal portion of the blower tube 10 are conveyed through the blower tube 10. And a collecting device 40 for collecting the coming paper sheets 2. In the paper sheet conveying apparatus 1, for example, an air flow generated by an air flow generating device 30 such as a blower is circulated through a delivery pipe 31, a connecting pipe 32, a blower pipe 10, a collecting apparatus 40, and a return pipe 33. It is configured. The blower pipe 10 is formed with a bent portion 10a bent in a U shape so as to constitute a circulation path. The return pipe 33 has an external air intake 34. Thereby, external air is taken in with return air, and it blows in the ventilation pipe 10 from the airflow generator 30 again.

  In the paper sheet transport apparatus 1, a plurality of feeding apparatuses 20 are arranged at appropriate positions on the blower pipe 10. The feeding device 20 includes a bill recognition device 21 disposed on the front side of the feeding and a bending device 22 disposed on the back side and connected to the blower tube 10.

  The bending device 22 constituting the feeding device 20 has a zigzag-shaped deformed portion 2b (bent portion) at the rear end portion in the transport direction with respect to the flat portion 2a at the front end portion in the transport direction of the paper sheet 2 as shown in FIG. Is formed). A wind pressure from an air flow (indicated by a hatched arrow in FIG. 2) flowing in the blower pipe 10 acts on the deformed portion 2 b, and the paper sheet 2 is conveyed in the blower pipe 10. In the present embodiment, a case where the deformed portion 2b of the paper sheet 2 is formed in a zigzag shape is shown. However, the present invention is not limited to this, and the deformed portion 2b is L-shaped as long as the wind pressure of the airflow acts. Alternatively, it may be bent or curved into a round shape.

  The collection device 40 includes a separation unit 50, a correction unit 70, and a storage unit 90 that are arranged in the order of conveyance from the terminal end side of the blower tube 10. Among these, the separation unit 50 separates the paper sheet 2 that has been transported through the blower tube 10 and the air flow that has given the driving force to the paper sheet 2, and sends the paper sheet 2 to the correction unit 70. It will be sent out. The correction unit 70 corrects the deformed portion 2 b of the paper sheet 2 sent out from the separation unit 50. The storage unit 90 stores the paper sheet 2 in an expanded state (flat state) after the deformation of the deformation unit 2b is corrected by the correction unit 70 by the correction unit 70.

  Next, the separation unit 50 in the present embodiment will be described in more detail. 3 and 4 are perspective views showing a state immediately before the separation part 50 is attached to the terminal part of the blower pipe 10 via the connection body 60, and FIG. 3 is a view seen from the inside of the recovery device 40. FIG. These are the figures seen from the blast pipe 10 side.

  The connection body 60 is provided with an opening 60a into which the separation unit 50 is fitted, an opening 60b through which airflow is exhausted, and a separation motor for driving the drive pulley 52 and the roller 54 (see FIG. 7) via gears. An opening 60c is formed. In addition, although the connection body 60 also has an opening connected with the termination | terminus part of the blast pipe 10, it is not illustrated. This is because in FIGS. 3 and 4, the blower pipe 10 and the connection body 60 are shown in a connected state.

  FIG. 5 shows a state in which the end portion of the blower tube 10 is viewed from the upper surface side, and FIG. 6 shows a cross-sectional state taken along line XX in FIG. FIG. 7 shows a state in which the separation unit 50 is viewed from the upper surface side. Furthermore, the state which looked at the isolation | separation part 50 attached to the termination | terminus part of the blast pipe 10 from the upper surface side in FIG. 8 is shown. 5, 7, and 8 are shown in a partially transparent state for ease of explanation.

  As shown in FIGS. 5 and 6, in the present embodiment, the blower tube 10 is formed as a rectangular tube having a rectangular cross section. Each wall surface 10b of the blower pipe 10 facing the surface of the paper sheet 2 being conveyed protrudes inward from the wall surface 10b at a required height to the inside of the blower pipe 10, and in the conveying direction of the paper sheet 2 A plurality of extending ribs 11 are formed. The interval between the tips of the ribs 11 formed on the both wall surfaces 10b is formed such that the deformable portion 2b of the paper sheet 2 can pass through. Moreover, the space | interval between the other opposing wall surfaces 10c is formed in the space | interval which can pass the paper sheets 2 without deform | transforming. The cross section of the paper sheet passage space formed between the tip of the rib 11 and the other opposing wall surface 10c is formed in a rectangular shape. In addition, the space | interval between the ribs 11 formed along the wall surface 10b is formed in the space | interval which the paper sheet 2 does not enter.

  As shown in FIG. 7 and FIG. 8, the separating unit 50 is a transport belt 51 that is stretched in parallel (along) the transport direction (x direction) of the paper sheet 2 transported through the blower tube 10. Is included. Further, the separating unit 50 includes a drive pulley 52 disposed on the inner side of the collection device 40 and a passive pulley 53 disposed on the blast tube 10 side in the transport direction. A conveyor belt 51 that is an endless belt is stretched around the drive pulley 52 and the passive pulley 53. For this reason, the tension direction of the transport belt 51 is parallel to the transport direction of the paper sheet 2.

  Note that the tension direction of the conveying belt 151 arranged in a V shape shown in FIG. 14 is not parallel to the sheet conveying direction (x direction). That is, the transport belt 151 is disposed in a direction that intersects the transport direction. As a result, the transport path of the transported paper sheets is narrowed by the transport belt 151. In this regard, in the present embodiment, a guide lever 61 having a guide surface 62 that guides the paper sheet 2 that has been transported through the blower tube 10 to the transport belt 51 is disposed at the tip of the transport belt 51. That is, the conveyance path is narrowed by the guide lever 61. The guide lever 61 will be described in detail later.

  The separation unit 50 is arranged at a position facing the conveyance surface (belt surface, front surface) of the conveyance belt 51 in a direction (y direction) intersecting the conveyance direction (x direction) of the paper sheet 2. A roller 54, a squeegee 55, and a guide plate 56 are provided. Here, the roller 54 is for clamping the paper sheet 2 together with the drive pulley 52 (conveying belt 51) and feeding it to the correction unit 70. The squeegee 55 is for squeezing the paper sheet 2 that has been conveyed. The guide plate 56 is used to guide the paper sheet 2 to the conveying belt 51 side, and the squeegee 55 is attached to the guide plate 56.

  Moreover, the opening 60b of the connection body 60 shown in FIG. The opening 60 b is a discharge port that discharges an air flow so that the conveyed paper sheet 2 comes into contact with the conveyance belt 51. By exhausting through the discharge port (opening 60 b), it is possible to generate a pressing force that presses the transported paper sheet 2 against the transport surface of the transport belt 51.

  A width (passage) through which, for example, about one sheet 2 can pass through the separating unit 50 is formed by the squeegee 55 disposed so as to face the conveying belt 51. The paper sheet 2 conveyed through the passage is pinched by the drive pulley 52 and the roller 54 and sent to the correction unit 60. Note that the transport direction of the fed paper sheets 2 is changed from the x direction to the y direction by the cover 59 of the separation unit 50 (see FIG. 7).

  As described above, the conveyance belt 51 conveys the paper sheet 2 that is in contact with the frictional force. Furthermore, the conveyance force of the conveyance belt 51 that conveys the paper sheet 2 increases as the belt length increases. Therefore, in the present embodiment, the conveying belt 51 is stretched with a desired length so as to extend in the conveying direction (the x direction in FIGS. 7 and 8) of the paper sheet 2 in the separating unit 50. A desired conveying force is secured.

  In this way, in the present embodiment, since the conveying force of the conveying belt 51 is increased, the sheet 2 can be conveyed without clogging in the separating unit 50. For this reason, it is reduced that the operation of the paper sheet conveying apparatus 1 is stopped due to the jam of the paper sheets 2 and the work is restored, and the operating rate of the paper sheet conveying apparatus 1 can be improved.

  In the present embodiment, as shown in FIG. 8, the transport belt 51 is stretched so that its tip protrudes from the housing 50 a of the separation unit 50 so as to be stretched up to the inside of the air duct 10. . Thereby, the paper sheet 2 can be conveyed so that it can be smoothly delivered between the blower tube 10 and the separation unit 50. That is, the force for conveying the paper sheet 2 can be smoothly switched from the propulsive force due to the wind pressure of the airflow to the conveying force. Also from this, clogging of the paper sheets 2 in the separation unit 50 can be reduced.

  Further, in the present embodiment, the separation unit 50 is disposed at the tip of the conveying belt 51 on the air blowing tube 10 side, and the guide surface 62 that guides the paper sheet 2 conveyed in the air blowing tube 10 to the conveying belt 51. And a guide lever 61 extending in the tension direction of the conveyor belt 51 is included. FIG. 9A shows a view of the guide lever 61 viewed from the upper surface side, and FIG. 9B shows a view of the guide lever 61 viewed from the side surface side. The guide lever 61 extends in the tension direction near the front end of the transport belt 51 so as to have a front end portion 61a and a rear end portion 61b. The guide lever 61 is configured by arranging two substantially triangular plate bodies 63 so as to face each other with a substantially rectangular plate body 64 interposed therebetween at a predetermined interval. In this manner, the guide surface 62 (hatched) is formed by the side portions of the two substantially triangular plate bodies 63 on the distal end portion 61 a side of the guide lever 61.

  By disposing such a guide lever 61 at the tip of the conveying belt 51 on the air blowing tube 10 side, the paper sheet 2 conveyed through the air blowing tube 10 can be attached to the back surface side of the conveying belt 51 and the air blowing tube 10. Even if it tries to enter the gap between the wall surface, it can be blocked by coming into contact with the guide lever 61 (guide surface 62). Further, since the obstructed paper sheet 2 is not separated from the air flow yet because it is in the air duct 10, it is guided to the conveying belt 51 by the guide surface 62 having a predetermined angle while receiving the wind pressure of the air flow. Can do. Thus, in this embodiment, since the gap between the back surface side of the conveyance belt 51 and the wall surface of the blower tube 10 is closed by the guide lever 61, the conveyed sheet 2 is used as a regular path. Can be passed.

  When this guide lever 61 is not provided, the paper sheet 2 conveyed through the blower tube 10 enters the gap on the back surface side of the conveyance belt 51 extending to the blower tube 10 and is clogged. Therefore, it may be impossible to collect. Therefore, in the present embodiment, by disposing the guide lever 61 having the guide surface 62 at the front end of the transport belt 51, the number of stoppages of the operation of the paper sheet transport apparatus 1 is reduced, and the paper sheet transport apparatus 1 The operating rate can be improved.

  Further, in the present embodiment, as shown in FIG. 8, the tip of the guide lever 61 on the guide surface 62 side is located above or below the rib 11 of the blower tube 10. In other words, the distal end portion 61a of the guide lever 61 is positioned between the ribs 11 formed along the wall surface 10b of the blower pipe 10 shown in FIG. The interval between the ribs 11 formed along the wall surface 10b is formed such that the paper sheet 2 does not enter, and the guide is formed so as to close the gap on the back surface side of the conveying belt 51 from between the ribs 11. Since the surface 62 is formed, the sheet 2 can be reliably prevented from entering the gap on the back surface side of the transport belt 51. For this reason, the operation of the paper sheet conveying apparatus 1 is not stopped, and the operating rate of the paper sheet conveying apparatus 1 can be improved.

  Next, the mounting process for mounting the separation unit 50 to the terminal portion of the blower tube 10 will be described with reference to the drawings, particularly regarding the disposition of the guide lever 61 in the blower tube 10. In FIG. 10, the state (FIG. 10B) in which the guide lever 61 is inserted into the terminal portion of the air pipe 10 from the state immediately before the separation portion 50 is attached to the terminal portion of the air pipe 10 (FIG. 10A). Then, the state (FIG.10 (c)) which attached the isolation | separation part 50 to the terminal part of the blast pipe 10 is shown. In addition, FIG.10 (c) respond | corresponds with the state which attached the isolation | separation part 50 to the terminal part of the blast pipe 10 shown in FIG.

  11 shows the state of the guide lever 61 (see FIG. 10 (a) and FIG. 10 (b)) (shown as guide lever 61A) when attached to the blower tube 10 when attached to the blower tube 10 in FIG. The state of the guide lever 61 (see FIG. 10C) (shown as a guide lever 61B) is shown.

In the present embodiment, the angle of the guide surface 62 with respect to the tension direction (x direction) of the conveyor belt 51 is made different with the attachment / detachment of the separation unit 50 from the blower tube 10. Specifically, the angle A before attachment (after removal) shown in FIG. 11A is narrower than the attachment angle B shown in FIG. For example, the tip 61a of the guide lever 61 is directed to the inside of the blower pipe 10 when the separation part 50 is attached to the blower pipe 10 (FIGS. 10 (a) and 10 (b)). In the state where 50 is attached to the air duct 10, it faces downward from the air duct 10 (FIG. 10C). That is, when attaching the separation part 50 to the terminal part of the air duct 10, the tip 61a of the guide lever 61 on the air duct 10 side is directed from the inner side to the outer side of the air duct 10, and when removing it, conversely, The tip 61a of the guide lever 61 on the side of the blower tube 10 is directed from the outer side of the blower tube 10 to the inner side, so that the conveying belt 51 stretched in parallel with the conveying direction of the paper sheet 2 is stretched. On the other hand, the mounting angle of the guide surface 62 is different.

  As described above, the guide lever 61 is provided with one effect of preventing the transported paper sheet 2 from entering the gap on the back surface side of the transport belt 51. However, if the angle of the guide surface 62 remains as wide as the angle B in the attached state, the distal end portion (the guide lever 61, the conveyor belt 51, etc.) of the separating portion 50 is inserted into the terminal portion of the blower tube 10. It becomes difficult to attach, for example, it may be caused to collide with the lip of the blower tube 10.

  Therefore, in the present embodiment, when the separation unit 50 is attached to the blower tube 10, the angle of the guide surface 62 with respect to the tension direction (x direction) of the transport belt 51 is set to be equal to that of the guide surface 62 with respect to the tension direction of the transport belt 51. Since the angle is small (see FIGS. 10A and 11A), it can be easily attached. When the separation part 50 is attached to the blower pipe 10, the side part between the front end part 61a and the rear end part 61b of the guide lever 61 comes into contact with the lip of the blower pipe 10 (see FIG. 10B). Thereafter, in a state in which the separating portion 50 is attached to the air duct 10, the rear end portion 61b of the guide lever 61 is brought into contact with the inner wall of the air duct 10 (see FIG. 10C), and the front end portion 61a of the guide lever 61 is abutted. You can avoid contact. For this reason, the angle of the guide surface 62 with respect to the tension | tensile_strength direction of the conveyance belt 51 can be made into a desired value. Therefore, since the separation part 50 can be easily attached to the blower tube 10, it does not take time to start up the operation of the paper sheet transport apparatus 1, and the operating rate can be improved.

  Thus, in order to change the angle of the guide surface 62 with respect to the tension direction of the conveyance belt 51 in accordance with the attachment / detachment of the separation unit 50 from the blower tube 10, the guide lever 61 is connected to the separation unit 50 from the blower tube 10. It can be rotated with the attachment and detachment. As shown in FIG. 9, the guide lever 61 is configured by arranging two substantially triangular plate bodies 63 so as to face each other with a substantially rectangular plate body 64 interposed at a predetermined interval. Yes. A through hole 65 is formed in the intermediate portion 61 c which is one vertex of the substantially triangular plate 63. A rod body 66 for allowing the guide lever 61 to turn is disposed through the through hole 65. In this way, the angle of the guide surface 62 with respect to the tension direction of the conveyor belt 51 can be varied with the attachment / detachment of the separation unit 50 from the blower tube 10.

  In the present embodiment, the rotation axis of the guide lever 61 and the rotation axis of the passive pulley 53 are common. Thereby, the paper sheet 2 can be conveyed as the guide surface 62 of the guide lever 61 and the conveyance surface of the conveyance belt 51 are continuous with the conveyance of the paper sheet 2. Further, since the guide lever 61 is disposed at the tip of the conveying belt 51, when the separation unit 50 is attached to the terminal portion of the blower tube 10, the guide lever 61 blows the conveying belt 51, the passive pulley 53, and the like. It is possible to prevent troubles such as damage caused by colliding with the inner wall of the tube 10. In this embodiment, the rotation shaft of the guide lever 61 and the rotation shaft of the passive pulley 53 are made common. However, if the guide lever 61 can be disposed at the tip of the transport belt 51, for example, a shaft is added. As a structure or a structure in which a boss is formed and a rotation hole is fitted, the rotation shaft of the guide lever 61 and the rotation shaft of the passive pulley 53 may be appropriately moved up and down and up and down.

  In the present embodiment, as shown in FIG. 9, the guide lever 61 is provided with an elastic body 67 that extends in parallel with the rod body 66 that is the rotation shaft thereof. For example, a tension spring can be used as the elastic body 67. The pulling spring (elastic body 67) is hooked in a round hole 68 formed in the plate body 64 and is disposed in a square hole 69 formed in the plate body 64. Further, as shown in FIGS. 11 and 12, the separating portion 50 is formed with a protruding portion 50 b that contacts the side surface of the elastic body 67. Specifically, the protrusion 50b abuts against the side surface of the elastic body 67 when the separation unit 50 is attached to the blower tube 10 (FIG. 12), and when the separation unit 50 is detached from the blower tube 10. It is formed so as not to contact (FIG. 11).

  When the separation unit 50 is attached to the blower tube 10 by the urging force of the elastic body 67, the angle of the guide surface 62 with respect to the tension direction of the transport belt 51 is reduced, and the angle of the guide surface 62 with respect to the tension direction of the transport belt 51 is decreased. can do. Thereby, since the separation part 50 can be easily attached to the blower pipe 10, it does not take time to start up the operation of the paper sheet transport apparatus 1, and the operation rate can be improved.

  Further, in the present embodiment, arc-shaped projecting portions projecting from the side portion connecting the front end portion 61a and the rear end portion 61b of the guide lever 61 are formed on the front end portion 61a and the rear end portion 61b of the guide lever 61, respectively. ing. For this reason, when attaching the separation part 50 to the terminal part of the air duct 10, the arcuate tip 61a and the rear end 61b of the guide lever 61 prevent damage such as damage to the inner wall of the air duct 10 and the like. can do.

  The present invention is widely used in the manufacturing industry of a paper sheet transport apparatus using the paper sheet transport method.
