Description

  The present invention relates to a technology that is effective when applied to a paper sheet conveying apparatus that conveys paper sheets such as banknotes by an air flow (air).

  The present inventor in Japanese Patent No. 4130697 (Patent Document 1) discloses a paper sheet transport device that transports paper sheets such as banknotes using an air flow. In this paper sheet conveying technique, a deformed portion (bent or curved portion) is formed at the rear end of the paper sheet in the conveying direction, and an air flow (wind pressure) is applied 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 a conveying pipe (also referred to as a blower pipe) in a state where the deformed portion is formed. When the paper is collected in the safe (collecting device) at the transport destination, the paper sheet and the air flow are separated by the separation unit. The separated paper sheets are stored in the storage unit in a state where the deformed portion is corrected and flattened by the correction unit.

  Here, the paper sheet conveying apparatus was bent by 90 degrees with a twisted pipe formed by twisting a required angle with respect to the axial direction of the conveying pipe and the paper sheet with one surface thereof being inward. It may be provided with a bent tube that can be conveyed in the direction. If this twisted tube and bent tube are connected to the straight portion of the transport tube, the transport can be turned with a small radius of curvature with respect to the paper sheets in the straight portion so that the end face side in the width direction of the paper sheets is inside. A path can be formed (paragraphs [0077]-[0080] in the specification of Patent Document 1).

  In JP-A-2003-306262 (FIG. 1 of Patent Document 2), in order to reduce the size of the banknote collection device, a banknote inserted in an upright posture is conveyed in the longitudinal direction to the storage unit, Then, the technique which conveys a banknote to a transversal direction and conveys it to the safe below a direction change part is disclosed.

Japanese Patent No. 4130697 JP-A-2003-306262

  FIG. 15 is a diagram for explaining a safe 134 (also referred to as a collection device) studied by the inventor disclosed in Patent Document 1. The safe 134 shown in FIG. 15 is provided upright in the vertical direction (z direction) with respect to the floor (xy plane).

  Inside the safe 134, a separation unit 94, a correction unit 96, and a storage unit 98 are provided. The separation unit 94 is provided at the end of the conveyance tube 22 and separates the paper sheet 32 and the air flow. A pair of conveying belts 100 are arranged around the pulley 103 in the separation unit 94. The conveying belt 100 is arranged so that the opposed conveying surface gradually narrows in a V shape from a guide plate 106 provided on the front side, and sandwiches the paper sheets 32 conveyed in the conveying tube 22 to correct the front. It can be sent to the section 96. A pair of parallel guide plates 107 are arranged in front of the conveyor belt 100 to guide the paper sheet 32 to the correction unit 96. Note that the air flow (air) in the transport pipe 22 is discharged by the discharge pipe 60.

  An inlet sensor 102 is disposed at the inlet of the correction unit 96. In the correction unit 96, four correction rollers 104 are arranged with a gap enough to allow paper sheets to pass between adjacent ones. A guide plate 108 having an arcuate cross section is disposed so as to cover the outer periphery of each correction roller 104 so as to form a certain sheet conveyance space between the outer peripheral surface of each correction roller 104.

  When the rotation shafts of the correction unit motors (not shown) and the gears fixed to the rotation shafts of the four correction rollers 104 are sequentially engaged with each other, the adjacent correction rollers 104 are rotated in opposite directions. As a result, the paper sheets 32 that have entered between the correction rollers 104 are conveyed in a zigzag shape, bent sequentially in the reverse direction, corrected to bend, and fed to the inlet side of the storage unit 98.

  An end detection switch 110 and a pair of transport rollers 111 are disposed at the entrance of the storage unit 98. The interior of the storage unit 98 is partitioned into two chambers, a first chamber 113 and a second chamber 114, by a press plate 112. The press plate 112 can be moved in the storage unit 98 by the storage unit motor 115. When the press plate 112 moves to one position (in the minus x direction in FIG. 15), the press plate 112 enters the second chamber 114 from the entrance. The paper sheet 32 can be fed, and the paper sheet 32 can be fed into the first chamber 113 when moved to the other side (plus x direction). A receiving plate 116 disposed in the first and second chambers 113 and 114 is received by a spring 117.

  The paper sheets 32 that have been transported by the transport tube 22 in parallel with the front and back surfaces in the vertical direction (z direction) are stored in the safe 134 with the front and back surfaces in parallel with the vertical direction. In such a safe 134, when a large amount of paper sheets 32 are stored, it is necessary to enlarge the storage unit 98 in the horizontal direction (x direction in FIG. 15). For this reason, when the storage unit 98 is increased in size, the entire safe 134 is increased in size, such as being fat.

  Further, in order to stack and store the paper sheets 32 not in the horizontal direction but in the vertical direction, as in the technique disclosed in Patent Document 2, a direction changing unit for changing the paper sheet conveyance direction is provided in the safe. If provided, the entire safe will be enlarged.

  The objective of this invention is providing the technique which can slim down the safe of a paper sheet conveying apparatus. 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.

  Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows. A paper sheet transport apparatus according to an embodiment of the present invention includes a transport pipe that forms a transport path for transporting paper sheets by an air flow, a twisted pipe formed by twisting in the axial direction of the transport pipe, and a paper sheet. Paper sheets that are connected to the twisting pipe and conveyed by an air flow in the conveyance path so that the front and back surfaces of the paper are parallel to the vertical direction. A separation unit that separates the air flow from the air flow, and a storage unit that stacks and stores the paper sheets separated from the air flow by the separation unit in a vertical direction so that the front and back surfaces thereof are parallel to the horizontal direction; It is equipped with.

(Embodiment 1)
FIG. 1 is a diagram for explaining the outline of a paper sheet transport apparatus 1 in the present embodiment, and FIG. 2 is an enlarged view of FIG. As shown in FIGS. 1 and 2, the paper sheet transport device 1 is installed on a so-called island where a plurality of game tables 4 (pachinko machines) are gathered between partition plates 2 and 3 and used in a game arcade. . The paper sheet transport apparatus 1 includes a safe 34, a transport path 10 that transports the paper sheet 32 by an air flow, and returns from the safe 34 to return to and from the safe path 34. And a charging unit 5. In addition, in the paper sheet transport apparatus 1, an input unit 5 (ball lending machine) is installed on the left side facing the game machine 4.

  Below, the structural member of the paper sheet conveying apparatus 1 is demonstrated. First, the input unit 5 will be described. As illustrated in FIG. 3, the input unit 5 inputs the paper sheet 32 into the transport path 10 with the front and back surfaces of the paper sheet 32 parallel to the vertical direction (z direction). In addition, the input unit 5 forms a zigzag-shaped deformed portion 32b at the rear end portion in the transport direction with respect to the flat surface portion 32a at the front end portion in the transport direction (x direction in FIG. 3) of the paper sheet 32. A wind pressure from an air flow (indicated by a hatched arrow in FIG. 3) flowing in the conveyance path 10 acts on the deforming portion 32 b, and the paper sheet 32 is conveyed in the conveyance path 10. In FIG. 3, the transport path 10 is formed such that the interval between the tips of the ribs 22 a formed on each of the opposing inner wall surfaces of the transport tube 22 is the interval through which the paper sheet 32 can pass.

  As shown in FIG. 4, in the insertion portion 5, one end side of an L-shaped swing arm 43 that swings the feed roller 41 positioned upstream of the pair of feed rollers 41, 41 about the shaft 42. One end of the spring 44 is fixed to the other end side of the swing arm 43, and the upstream feed roller 41 is urged by the spring 44 so as to be in pressure contact with the downstream feed roller 41. Although not shown, a pair of L-shaped swing arms 43 are provided, and the other end of the upstream feed roller 41 is also rotatably supported.

  The shield shafts 45 and 46 are arranged in parallel with the feed rollers 41 and 41, respectively, and at a small interval from the feed rollers 41 and 41. The inclined guide portion 47 extends in the direction of the upstream feed roller 41 and extends away from the transport path 10, and a stopper 48 is formed at the end. Further, on the downstream side of the inclined guide portion 47, a bag-like portion 49 is formed that extends in the direction of the downstream feeding roller 41 and gradually abruptly separates from the conveyance path 10.

  In the state shown in FIG. 4, the paper sheet 32 is inserted into the insertion unit 5 and the bill recognition operation is performed. At this time, the feeding rollers 41 and 41 are not yet rotated. From this state, when a bill recognition operation is performed and the paper sheet 32 is fed in the direction of the feed rollers 41 and 41 by a feed roller (not shown), as shown in FIG. Turns the movable claw piece 51 against the urging force of a spring (not shown), and turns on the entrance light sensor 30. When this ON signal is input to the control unit 29, the control unit 29 drives a feed motor (not shown) so that both the feed rollers 41, 41 rotate in the feed direction.

  When the paper sheet 32 is fed by the both feeding rollers 41 and 41 and the rear end portion of the paper sheet 32 passes between the fixed guide portion 50 and the movable claw piece 51, the movable claw piece 51 is springed (not shown). Is rotated to the original position by the urging force, the paper path is blocked by the fixed guide portion 50 and the movable claw piece 51, and the entrance light sensor 30 is turned off again, and this off signal is input to the control portion 29. Is done.

  When the off signal is input to the control unit 29, the control unit 29 temporarily stops the feed motor and rotates the feed motor in the reverse direction by a predetermined angle. Thereby, the paper sheet 32 is pulled back a predetermined distance. When the paper sheet 32 is pulled back in this way, the rear end of the paper sheet 32 comes into contact with the inclined guide portion 47, the rear end portion of the paper sheet 32 is pulled back along the inclined guide portion 47, and the rear end is It contacts the stopper 48.

  When the feeding motor is further rotated in the reverse direction, the paper sheet 32 gradually enters the bag-like portion 49 on the rear end side, and is formed in a folded shape along the inner wall of the bag-like portion 49. When the feeding motor is further rotated in the reverse direction, the retracted paper sheet 32 forms another deformed portion by curving the middle part of the paper sheet 32. If the feed motor is further rotated in the reverse direction, the deformation is emphasized. When this state is reached, the feeding motor is stopped (see FIG. 6).

  Subsequently, the feeding motor is rotated forward again. As a result, as shown in FIG. 7, the rear end portion of the folded paper sheet 32 enters between the pair of feed rollers 41, 41. When the feed motor is further rotated, the looped folded end of the paper sheet 32 tries to pass between both the feed rollers 41 and 41, and at that time, the resistance force from the paper sheet 32 is caused by the spring 44. The upstream feed roller 41 is rotated in a direction away from the downstream feed roller 41 against the urging force. Thereby, when passing between both feeding rollers 41, 41, an appropriate pressing force is applied to the looped folded end of the paper sheet 32, and the rear end portion of the paper sheet 32, as shown in FIG. It is deformed so as to be convex toward the feeding rollers 41 and 41 in a considerably strong state. In this way, a deformed portion 32 b on which the wind pressure of the airflow acts by the input portion 5 is formed on the paper sheet 32 conveyed in the conveying path 10.

  Next, the safe 34 configured by a casing including the separation unit 94 and the storage unit 98 will be described with reference to FIG. In the safe 34, the rooms are divided into upper and lower sides. An upper chamber, which is a fan chamber, is provided with a fan 7 that is connected to the starting end 10 a of the transport path 10 and generates an air flow in the transport path 10. On the door of the fan chamber 6, a display unit 8 for displaying the operation state of the paper sheet transport device 1 is attached.

  In the lower chamber, the separation unit 94, the correction unit 96, the reject storage unit 11, the identification unit 12, the storage unit 98, the cable through hole 14, the power breaker 15, the changeover switch 16, the communication connector 17, the operation unit 18, and the control A substrate 21 is provided.

  The separation unit 94 connected to the terminal end 10b of the transport path 10 separates the paper sheets 32 transported by the air flow in the transport path 10 from the air flow. The correction unit 96 corrects the deformed portion 32b of the paper sheet 32 so as to be flat. In addition, the storage unit 98 is configured to drop the paper sheet 32 separated from the air flow by the separation unit 94, for example, so that the front and back surfaces of the paper sheet 32 are parallel to the horizontal direction (x, y direction). Are stacked and stored in the vertical direction (z direction). In the storage unit 98, for example, 1000 sheets of paper sheets 32 can be stored.

  The identification unit 12 identifies the type of the paper sheet 32 that has been conveyed (for example, four types of thousand yen bill, 2000 yen bill, 5000 yen bill, and 10,000 yen bill). The reject storage unit 11 stores paper sheets 32 that cannot be identified by the identification unit 12. In FIG. 9, the reject storage unit 11 is provided on the back side of the correction unit 96.

  The cable through hole 14 is a hole through which the connection cable to the insertion portion 5 is passed. The power breaker 15 is for energizing the paper sheet transport apparatus 1 with electricity. The changeover switch 16 is, for example, a slide switch that switches operation modes of “fan replacement”, “operation”, and “loader replacement”. The communication connector 17 is a connector for connecting to the outside for log acquisition, for example. The operation unit 18 is for operating the state of the paper sheet transport apparatus 1 with a button. The control board 21 is mounted with a CPU that controls the input unit 5, the fan 7, and the like.

  Next, the conveyance path 10 will be described. As shown in FIGS. 1 and 2, the conveyance path 10 that forms the paper sheet 32 by the air flow is curved (U-shaped) with a straight portion (see FIG. 10) that linearly conveys the paper sheet 32. And a torsion tube 23 formed by twisting a required angle with respect to the axial direction of the transport tube 22 (paper sheet transport direction) (see FIGS. 11A and 11). (B), FIG. 11 (c), FIG. 11 (d), and FIG. 11 (e)). A conveying pipe 22 (straight line portion) is connected at the start end 10 a of the conveying path 10, and a twisted pipe 23 is connected at the terminal end 10 b of the conveying path 10.

  As shown in FIG. 10, a plurality of ribs 22 a extending in the length direction and projecting inward at a required height are formed on each of the opposed inner wall surfaces. The interval between the tips of the plurality of ribs 22a formed on each of the opposing inner wall surfaces is a rectangular opening shape (indicated by a broken line in FIG. 10) as an interval through which the paper sheet 32 can pass without being deformed. )) Is formed. The conveyance path 10 in the conveyance pipe 22 is formed so that the length of the rectangular opening shape is parallel to the vertical direction (z direction).

  Further, as shown in FIG. 11E, the twisted tube 23 is formed with a plurality of ribs 23a extending in the length direction and projecting inward at a required height on each of the opposing inner wall surfaces. The interval between the tips of the plurality of ribs 23a formed on each of the opposing inner wall surfaces is a rectangular opening shape (in FIG. 11 (e), as an interval through which the paper sheet 32 can pass without being deformed. A conveyance path 10 (shown by a broken line) is formed.

  The conveying path 10 in the twisted tube 23 is formed so that the longitudinal length of the rectangular opening is parallel to the horizontal direction (see FIG. 11D) from the vertical direction (see FIG. 11B). Specifically, the twisted tube 23 is formed by combining a plurality of twisted members 23A, 23B, 23C, 23D, 23E, and 23F. This makes it clear that the paper sheet 32 conveyed by the air flow can be conveyed in all directions by combining the twist members 23A to 23F.

  As described above, the paper sheet transport apparatus 1 according to the present embodiment is formed by twisting the transport pipe 22 constituting the transport path 10 that transports the paper sheet 32 by the air flow and the axial direction of the transport pipe 22. The tube 23 and the input unit 5 for feeding the paper sheet 32 into the transport path 10 and the twisted pipe 23 are connected so that the front and back surfaces of the paper sheet 23 are parallel to the vertical direction. The separation unit 94 for separating the paper sheet 32 conveyed by the flow from the air flow, and the paper sheet 32 separated from the air flow by the separation unit 94 so that the front and back surfaces thereof are parallel to the horizontal direction. And a storage portion 98 that is stacked and stored in the vertical direction.

  By the way, a paper sheet transporting apparatus that can be installed is required even in a game hall having a small floor area. Therefore, in the input unit 5 in the present embodiment, the front and back surfaces of the paper sheet 32 are input to the conveyance path 10 in parallel with the vertical direction (z direction). For this reason, the width B (refer FIG. 1) of the insertion part 5 can be made narrower than the case where the front and back surfaces of the paper sheet 32 are input in parallel with the horizontal direction (x and y directions in FIG. 1). Since the front and back surfaces of the paper sheets 32 are input from the input unit 5 in parallel with the vertical direction, the front and rear surfaces of the paper sheets 32 are also transferred in parallel with the vertical direction in the transport pipe 22. Moreover, in the curved part 22A of the conveyance pipe 22, a curvature radius can be made smaller than the case where it conveys in parallel with a horizontal surface by conveying front and back in parallel with a vertical direction.

  Further, in a game arcade having a small floor area, the opposing game tables 4 may be installed with a narrow interval A (see FIG. 1) (for example, 500 mm). However, as described with reference to FIG. 15, the front and back surfaces of the paper sheet 32 that has been transported by the transport pipe 22 in parallel with the vertical direction (z direction) and the front and back surfaces of the paper sheet 32 are in the vertical direction (z direction). The safes 134 stored in parallel are stacked and stored in the horizontal direction (x and y directions), and the storage unit 98 is enlarged in the horizontal direction. For this reason, when the storage unit 98 is increased in size, the entire safe 134 is also increased in size as if it is fat, and it is not possible to meet the demands at a game hall with a small floor area.

  Therefore, in the paper sheet transport apparatus 1 according to the present embodiment, the twisted tube 23 formed so that the length of the rectangular opening shape is parallel to the horizontal direction (x, y direction) from the vertical direction (z direction) is transported through the transport path. 10 terminal portions 10b. For this reason, the paper sheets 32 whose front and back surfaces are transported in parallel with the vertical direction in the transport path 10 (transport tube 22) are transported by the twisted tube 23 in parallel with the front and back surfaces. Become. The paper sheets 32 whose front and back surfaces are parallel to the horizontal direction pass through the separation unit 94 and the correction unit 96, and are stored in the storage unit 98 by stacking the front and back surfaces in the vertical direction in parallel with the horizontal direction. (See FIG. 9).

  Thus, for example, even when a large amount of paper sheets 32 are stored, the storage portion 98 can be tallened in the vertical direction without being enlarged in the horizontal direction. Therefore, the safe 34 as a whole can be slimmed.

  Further, in the present embodiment, the plurality of twist members 23A and 23B are arranged such that the transport pipe 22 and the twist pipe 23 provided at the start end 10a and the end end 10b of the transport path 10 reciprocated overlap each other in the vertical direction (z direction). 23C, 23D, 23E, and 23F are adjusted by adjusting the length, the angle with respect to the transport direction, and the like to form the twisted tube 23 (see FIG. 11). That is, by using such a twisted tube 23, as shown in FIG. 9, the start end 10a and the end end 10b of the transport path 10 can be arranged in the vertical direction so that the arrangement area can be reduced. Thus, there is a degree of freedom in the arrangement of other members arranged inside the safe 34. Thereby, the safe 34 as a whole can be slimmed.

  In addition, using the technique of the present embodiment, as shown in FIG. 12, a twisted tube 23 can be provided inside the safe 34A as the end 10b of the transport path 10. Thus, for example, even when a large amount of paper sheets 32 are stored, the storage portion 98 can be tallened in the vertical direction without being enlarged in the horizontal direction. However, it is necessary to secure the floor area in the horizontal direction by the length of the twisted tube 23. On the other hand, as shown in FIG. 2, the transport path 22 is configured as the start end 10 a of the transport path 10 and connected outside the safe 34, and is connected as the end 10 b of the transport path 10 outside the safe 34. By comprising the twisted tube 34, it can be made slimmer than the safe 34A.

(Embodiment 2)
FIG. 13 is a diagram for explaining the outline of the paper sheet conveying apparatus 1A in the present embodiment. The paper sheet conveying apparatus 1A is installed on a so-called island where a plurality of game tables 4 (pachislot tables) are gathered between the partition plates 2 and 3, and is used in a game hall. Similarly to the paper sheet transport apparatus 1 described in the first embodiment, the paper sheet transport apparatus 1A also transports the paper sheet 32 by the air flow and returns from the safe 34 back and forth. 10 and a plurality of input sections 5 for inputting paper sheets 32 into the conveyance path 10. In the paper sheet transport apparatus 1A, the input unit 5 is installed on the right side facing the game table 4.

  In the paper sheet transport apparatus 1A, the transport pipe 22 at the start end 10a of the transport path 10 is bent outside the safe 34 so as to intersect the twisted pipe 24 (shown as a cross section 22B in FIG. 13). . As shown in FIG. 14 (e), a plurality of torsion members 24A, 24B, so that the transport pipe 22 and the twist pipe 24 provided at the start end 10a and the end 10b of the transport path 10 reciprocated in this way intersect each other. 24C, 24D, 24E, 24F, and 24G are combined to form a twisted tube 24 by adjusting the length, the angle with respect to the transport direction, and the like.

  As shown in FIG. 14E, the torsion pipe 24 is formed with a plurality of ribs 24a extending in the length direction and projecting inward at a required height on each of the opposing inner wall surfaces. The interval between the tips of the plurality of ribs 24a formed on each of the opposing inner wall surfaces is a rectangular opening shape (in FIG. 14 (e), as an interval through which the paper sheet 32 can pass without being deformed) A conveyance path 10 (shown by a broken line) is formed.

  Even if such a twisted tube 24 is used, the area of the start end 10a and the end end 10b of the conveyance path 10 arranged inside the safe 34 can be reduced, so that other members arranged inside the safe 34 can be reduced. A degree of freedom in placement is born. Thereby, the safe 34 as a whole can be slimmed.
