Description

The present invention relates to a technique for conveying paper sheets by airflow.

  2. Description of the Related Art Conventionally, when transporting banknotes at a game hall or the like, a transport device that transports bills using a belt or a roller has been used. However, in such a transport apparatus, the entire apparatus becomes large in a game area having a large area, and the running cost for driving the belt and the rollers becomes very high.

  Then, this inventor has proposed the conveyance apparatus which conveys paper sheets, such as a banknote, using an airflow (patent document 1). According to the transport device using such an air flow, the device can be downsized and the running cost can be reduced as compared with a transport device using a belt or a roller.

Japanese Patent No. 4130697

  The paper sheet conveying technique disclosed in Patent Document 1 forms a deformed portion (bent or curved portion) at the rear end of the paper sheet in the conveying 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. Further, when the sheet is collected in the collection apparatus at the transport destination, the paper sheet on which the deformed portion is formed is processed so that the deformed portion is corrected and flattened (stretched).

  Here, the deformation | transformation part formed in paper sheets is demonstrated. For example, a deformed portion formed in, for example, a bent or curved shape for transporting paper sheets may vary in deformation angle depending on the state in which the paper sheets are used. In addition, the degree of deformation of the deformed portion of the paper sheet is increased or decreased due to contact with the other paper sheets or a collision, contact with the inner wall of the air duct, etc. while being transported in the air duct. End up. As described above, the degree of deformation of the deformed portion formed on the paper sheet varies depending on various factors.

  Further, at the time of collection, the paper sheet having a deformed portion is corrected by, for example, passing the correction roller while zigzag bending between the correction rollers. If the paper sheet passes through the correction roller while being folded in half, the paper sheet is folded in half. This causes a problem that the sheet is crushed as it is, further creased, and one side or a part thereof is collected while being strongly folded, that is, not corrected.

  Therefore, even when paper sheets having different degrees of deformation have been conveyed, it is required to collect the paper sheets in a stretched state using a technique that more reliably eliminates the deformed portion.

  The present invention meets the above-mentioned demands, and an object of the present invention is to provide a technique capable of eliminating the deformed portion of the paper sheet formed for conveyance.

A blower tube, a feeding device that feeds paper into the blower tube, an airflow generator that generates an airflow in the blower tube, and a paper sheet that is conveyed through the blower tube to the end of the blower tube In a paper sheet transport method using a paper sheet transport device having a recovery device for recovering paper, a rear end portion of the paper sheet is deformed into a bent or curved shape by a bending device disposed in the feeding device. The squeegee protrusion disposed on the front side of the correction unit of the recovery device is bent by abutting the inner side surface of the bent or bent paper sheet and squeezing the bent or bent portion. Alternatively, the curved portion is restricted to open, and the correction roller included in the correction portion is used to pass the paper sheets in a zigzag shape, thereby bending the paper sheets in the reverse direction and correcting the deformation of the paper sheets. To do. The paper sheet is a bill.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows. The technique which can eliminate the deformation | transformation part of the paper sheets formed in order to convey can be provided.

  First, an overview of the entire sheet transport apparatus 20 will be described with reference to FIG. Reference numeral 22 denotes a blower pipe, which is bent into a U shape at a bent portion 23 in the example of FIG. Reference numeral 24 denotes a blower unit (air flow generator) composed of a blower or the like, which is connected to the inlet part of the blower pipe 22 via the delivery pipe 25 and the connecting pipe 26 and blows air into the blower pipe 22. An air flow is generated inside.

  28 is a device for feeding paper such as banknotes, and feeds the paper into the blower tube 22. The feeding device 28 has a bill recognition device 29 disposed on the front side and a bending device 30 disposed on the back side. The banknote identification device 29 discriminates the type and authenticity of the inserted banknote, and since a known mechanism can be adopted, detailed description is omitted.

  As shown in FIG. 2, the bending device 30 is bent or curved in an L shape, a round shape, or a zigzag shape with respect to the flat surface portion 32 a of the paper sheet 32, for example, on the rear end side in the conveyance direction of the paper sheet 32. A temporary deforming portion 32b is formed. In Patent Document 1 in which the technique proposed by the present inventor is disclosed, a bending apparatus is described in detail. The wind pressure from the airflow flowing through the blower tube 22 acts on the temporary deforming portion 32b, and the paper sheet 32 is conveyed through the blower tube 22. The term “temporary” means that it can be corrected to be flat later.

  As shown in FIG. 1, a plurality of such feeding devices 28 are disposed at appropriate positions on the air duct 22. For example, the paper sheet transport device 20 is used for a bill collection device in a pachinko parlor, and in this case, the feeding device 28 corresponds to a bill input unit in a ball lending machine, and is usually located next to one pachinko machine. A single feeding device 28 is provided.

  The paper sheets 32 conveyed by the air flow in the blower tube 22 are collected by a collecting device 34 provided at the terminal portion of the blower tube 22. Only the paper sheets 32 are collected by the collection device 34, and the air flow that has passed through the collection device 34 is returned to the air flow generation device 24 by the return pipe 36. An external air intake 37 is opened in the return pipe 36, and external air is taken together with the return air so that it is blown again from the air flow generator 24 into the blower pipe 22.

  As shown in FIG. 3, the blower tube 22 that transports the paper sheet 32 is formed in a rectangular tube having a rectangular cross section. The inner surface of the blower tube 22 at the required height from the wall surface 22a, 22a on each wall surface (one opposed wall surface 22a, 22a) of the blower tube 22 facing the front surface (including the back surface) of the paper sheet 32 to be fed. And a plurality of ribs 40 extending in the blowing direction. The interval between the tip portions of the ribs 40 formed on both the wall surfaces 22a and 22a is formed such that the deformable portion 32b of the paper sheet 32 can pass through. Moreover, the space | interval between the other opposing wall surfaces 22b and 22b is formed in the space | interval which can pass the paper sheet 32, without deform | transforming. Therefore, the cross section of the paper sheet passage space formed between the leading end of the rib 40 and the other opposing wall surface 22b, 22b is formed in a rectangular shape.

  Next, the principle of conveying the paper sheet 32 using the paper sheet conveying apparatus 20 will be described with reference to FIG. By the bending device 30 (see FIG. 2) of the feeding device 28, the rear end side in the conveying direction is deformed into an L shape, an arc shape, a cylindrical shape or a zigzag shape with respect to the flat surface portion 32a, and the deforming portion 32b is formed. The formed paper sheet 32 is fed into the blower tube 22. Thus, the paper sheets 32 fed into the blower tube 22 have a space A with the ribs 40a on the deformed portion 32b side, and air flows between the ribs 40a (see FIG. 3). It does not stick to the side. On the opposite side of the rib 40b, air flows between the rib 40b along the outer wall of the deformed portion 32b, and a force acts to pull the deformed portion 32b away from the rib 40b. Since the air is flowing between them (see FIG. 3), the paper sheet 32 does not adhere to the rib 40b side.

  In this way, the paper sheet 32 receives almost no resistance from the ribs 40a and 40b, and as a result, the wind pressure of the airflow acting on the deformed portion 32b does not cause fluttering at the tip portion, and is extremely smooth. It moved in the blower tube 22. As a result of observation, since the paper sheets 32 move at a speed close to the wind speed, initially, after obtaining the propulsive force by receiving the wind pressure of the air flow acting on the deformable portion 32b, the paper sheet 32 moves along the air duct 22 along with the air flow. It was confirmed that the air flowed in a state where the air flowed and moved smoothly and transported in the air duct 22.

  Here, the collection | recovery apparatus 34 shown in FIG. 5, FIG. 6 is demonstrated. The collection device 34 is configured to include a separation unit 94, a correction unit 96, and a storage unit 98 that are sequentially provided in the conveying direction from the terminal end side of the blower tube 22. The collection device 34 is detachably attached to the terminal end of the blower tube 22 and collects the paper sheets 32 conveyed through the blower tube 22.

  First, the separation unit 94 disposed in the collection device 34 will be described. The separation part 94 is provided at the terminal part of the blower pipe 22 and separates the paper sheet 32 and the air flow. A paper sheet detection sensor 99 is disposed at the entrance of the separation unit 94. A pair of conveyor belts 100 are disposed in the separation unit 94. Reference numeral 101 denotes a drive motor (separator motor) for driving the pair of transport belts 100. Reference numeral 106 denotes a guide plate for guiding the paper sheet 32 between the pair of conveying belts 100. In addition, a one-way clutch mechanism (not shown) is inserted in the pulley 103 around which the conveyor belt 100 is wound, and the paper sheet 32 is pulled out in the direction of the paper sheet correction section 96 even when the separation section motor 101 is stopped. It is possible.

  The conveying belt 100 is disposed so that the opposite conveying surface gradually narrows in a V shape (see FIG. 5), sandwiches the paper sheets 32 conveyed in the blower tube 22, and sends them to the front correction unit 96. It is possible. That is, in the collection device 34, the width of the passage through which the paper sheet 32 passes from the terminal end of the blower tube 22 to the correction roller 104 of the correction unit 96 is gradually narrowed.

  Reference numeral 60 denotes a discharge pipe that discharges only the air flow to the outside. The discharge pipe 60 is connected to the return pipe 36 (see FIG. 1), and the air flow is returned to the air flow generator 24. Thereby, a part of the air flow is circulated and blown.

  Since the paper sheets 32 conveyed by the wind pressure of the air flow in the blower tube 22 are completely separated from the air flow, they need to be taken over by another means and sent to the correction unit 96 before that. is there. Therefore, in the separation unit 94, the width of the passage through which the paper sheet 32 passes from the terminal portion of the blower tube 22 to the correction unit 96 by the pair of transport belts 100 so that the paper sheet 32 is sandwiched between the pulleys 103. It is becoming narrower.

  Next, the correction part 96 arrange | positioned at the collection | recovery apparatus 34 is demonstrated. The correction unit 96 is provided between the separation unit 94 and the storage unit 98, and corrects the deformation unit 32 b of the paper sheet 32. A pair of parallel guide plates 107 are arranged in front of the conveyance belt 100 to guide the paper sheet 32 to the correction unit 96. An inlet sensor 102 is disposed at the inlet of the correction unit 96. In the correction unit 96, there is a gap that allows the paper sheets 32 to pass between the four correction rollers 104 and the 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 that a fixed space is formed between the correction roller 104 and the outer peripheral surface.

  Reference numeral 105 denotes a drive motor (correction unit motor) for driving the correction roller 104. When the rotation shaft of the correction unit motor 105 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.

  Next, the storage unit 98 disposed in the collection device 34 will be described. 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 is moved to one position (front side in FIG. 5), the paper is fed from the entrance into the second chamber 114. The leaves 32 can be fed, and the paper sheets 32 can be fed into the first chamber 113 when moved to the other side (back side). Reference numeral 116 denotes a receiving plate disposed in the first and second chambers 113 and 114 and is received by a spring 117.

  The collecting principle of the paper sheets 32 using the collecting device 34 will be described with reference to FIGS. When the paper sheet detection sensor 99 detects that the leading end (one end) of the paper sheet 32 has arrived, the separation unit motor 101 is driven, the transport belt 100 is driven, and the paper sheet 32 is sent to the correction unit 96. It is. When the paper sheet 32 is detected by the entrance sensor 102, the separation unit motor 101 is stopped, while the correction unit motor 105 is driven to rotate the four correction rollers 104, and the paper sheet 32 is between the correction rollers 104. In the meantime, it is bent several times in the front and back direction, and is fed into the storage unit 98 with the bending corrected. When the end (other end) of the paper sheet 32 is detected by the end detection switch 110, the correction unit motor 105 is stopped. The conveyance roller 111 is driven or stopped together with the correction roller 104.

  In the storage unit 98, the press plate 112 is moved in one direction (the back side in FIG. 5), and the paper sheets 32 are carried into the first chamber 113 from the entrance. When it is detected by the end detection switch 110 that the end of the paper sheet 32 has passed, the storage unit motor 115 is driven, the press plate 112 moves in the first chamber 113, and the paper sheet is transferred to the receiving plate 116. 32 is pressed. In this state, the press plate 112 is stopped, and the sheet 32 can be fed into the second chamber 114 from the entrance, and the sheet 32 fed next is fed into the second chamber 114. , Housed. In this way, the sheets 32 are sequentially taken into the first chamber 113 and the second chamber 114 and stored.

  However, when collecting the paper sheets 32 conveyed using the collecting device 34 as shown in FIGS. 5 and 6, the following problems may occur.

  For example, in the collection device 34, the paper sheet 32 that has been conveyed has many of the deformed portions 32b whose rear end portions are bent or curved, and the passages are gradually narrowed (in FIG. The belt is stretched and opened by the separating portion 94 (shown to be narrowed in a V shape by the belt 100). However, some of the paper sheets 32 that are strongly deformed are guided to the correction section 96 with the entire rear part of the paper sheets or a part of the corners, etc. completely folded in this path. Sometimes.

  In front of the storage unit 98, there is provided a device (correcting unit 96) for correcting the deformation of the paper sheet 32 by passing between the correcting rollers 104 while being bent in a zigzag manner. The straightening part 96 is further strongly creased and one side or a part thereof is strongly folded and accommodated in the storage part 98.

  In addition, a plurality of paper sheets 32 may overlap in the passage of the separation unit 94, and a state in which a plurality of sheets are folded when passing through the correction unit 96 may occur. In this case, the paper sheets 32 are clogged before and after the correction unit 96. Furthermore, when the plurality of paper sheets 32 are overlapped and integrated, the total length of the paper sheets is apparently extended and does not fit in the storage unit 98 and protrudes. For this reason, the problem that the system itself of the paper sheet conveying apparatus 20 stops will generate | occur | produce.

  Therefore, in Embodiments 1 and 2 shown below, when the transported paper sheet 32 is collected in the storage unit 98, the paper sheet 32 is squeezed by the separation unit 94 and then the paper sheet is processed by the correction unit 96. The correction of the deformed portion 32b of the class 32 will be described. In other words, the sheet 32 is rubbed so as to be pressed from the front end to the end, so that, for example, even the folded paper sheet 32 is stretched and opened. The deformed portion 32b is completely corrected. Therefore, the deformation of the deformable portion 32b of the paper sheet 32 can be satisfactorily eliminated. Moreover, the paper sheets 32 before and after the correction unit 96 can be prevented from being jammed. Furthermore, the conveyed paper sheets 32 can be stored in the storage unit 98 satisfactorily. As described above, the means for squeezing the paper sheets 32 is performed by the separation unit 94 in front of the correction unit 96.

(Embodiment 1)
FIG. 7 is a perspective view of the separation part 94a in the present embodiment, FIG. 8 is a perspective view showing a part of the separation part 94a in an exploded manner, and FIG. 9 is a partly exploded view of the separation part 94a. It is a top view. FIG. 10 shows a squeegee 301 included in the separation portion 94a, which is (a) a side view and (b) a top view. The separation unit 94a shown in the present embodiment is provided at the terminal end of the blower tube 22 in the same manner as the separation unit 94 of the paper sheet transport device 20 described above, and the air flow with the paper sheet 32 that has been transported. Although separated, some of the configurations are different. In particular, a squeegee 301 having a protrusion 302 is disposed on the front side of the correction unit 96 having the correction roller 104. The other configuration of the paper sheet transport device 20, the transport principle of the paper sheet 32, and the like are as described above.

  Since the paper sheets 32 conveyed by the wind pressure of the air flow in the blower tube 22 are completely separated from the air flow by the separation unit 94a, the paper sheets 32 are stopped. Need to be sent to. Therefore, in the separation unit 94a, the conveying belt 100 that conveys the fed paper sheet 32 is disposed to face the squeegee 301, and the roller 321 and the pulley 103 that sandwich the paper sheet 32 are disposed as the correction roller 104. And the squeegee 301. In the separation unit 94 a, the paper sheet 32 from the terminal end portion (air blow pipe side port 323) to the correction unit 96 (correction unit side port 324) of the air blow tube 22 so that the paper sheet 32 is sandwiched between the roller 321 and the pulley 103. The width of the passage through which is passed is gradually narrowed. The roller 321 and the pulley 103 are connected to the separation unit motor 101 shown in FIG. 6 through a gear. Further, a discharge pipe 60 as shown in FIG. 6 is provided on the roller 321 and pulley 103 side.

  As described above, the separation unit 94a is provided with the air duct side port 323 serving as an inlet of the conveyed paper sheet 32 and the correction unit side port 324 serving as an outlet. The air duct side port 323 is about the same size as the cross section of the air duct 22, and is large enough to allow the paper sheet 32 having the deformed portion 32b to pass through. The size is such that it can pass at the side edge.

  In the separation unit 94a, the width of the passage through which the paper sheets 32 from the terminal end of the blower tube 22 to the correction unit 96 pass is gradually narrowed in a V shape by the four conveyor belts 100 and the guide plate 326. (See FIG. 9). That is, in the collection device 34, the width of the passage through which the paper sheet 32 passes from the terminal end of the blower tube 22 to the correction unit 96 is gradually narrowed. As shown in FIG. 5, a pair of guide plates 107 provided in parallel are arranged in front of the correction unit side port 324 to guide the paper sheet 32 to the correction unit 96.

  In the present embodiment, as shown in FIG. 9, a protrusion 302 that protrudes from the guide plate 326 toward the transport belt 100 is provided in the middle of the path through which the paper sheet 32 passes. Specifically, a squeegee 301 having a protrusion 302 as shown in FIG. 10 is attached to the guide plate 326. The front side surface 303 of the protrusion 302 is formed on an inclined surface that abuts at the end (rear edge) of the conveyed paper sheet 32 and restricts the bent or curved deformed portion 32b to open. For this reason, since the terminal end (rear edge) of the paper sheet 32 having the bent or curved part (deformed part 32b) that has been conveyed receives resistance at the protrusion 302, the paper sheet 32 is stretched and opened. can do. This point will be described in more detail below.

  11-13 is explanatory drawing which shows the mode of the paper sheets 32 in conveyance in the separation part 94a. In FIG. 11, the state in which the paper sheet 32 viewed from the side of the squeegee 301 is conveyed is shown in the order of (a) to (c). Also, FIGS. 12A to 12D and FIGS. 13A to 13D correspond to each other. In FIG. 12, the state in which the paper sheet 32 viewed from the upper surface side of the squeegee 301 is conveyed, FIG. 13 shows a state in which the paper sheet 32 viewed from the side of the squeegee 301 is conveyed. In addition, the linear arrow which goes to the right side shown in FIGS. 11-13 has shown the conveyance direction of the paper sheet 32. FIG.

  First, as shown in FIGS. 9 and 11, the paper sheet 32 that has entered from the air duct side port 323 of the separating portion 94 a is further narrowed by the squeegee 301 attached to the guide plate 326. Separated from the stream. Specifically, in order to separate the paper sheet 32 and the air flow, the air flow is discharged while changing the air flow in the direction of the transport belt 100 and pressed against the transport belt 100, so The paper sheets 32 that have received the pressing force obtain a frictional force with the conveying belt 100 and are conveyed while being separated. The paper sheets 32 to be conveyed while being separated in this way pass through between the protrusion 302 and the conveying belt 100 toward the correction unit side port 324.

  In the squeegee 301, as shown in FIG. 10A, the width of the front side surface 303 of the protruding portion 302 is narrower than that of the rear side surface 304, and the width of the rear side surface 304 of the protruding portion 302 is gradually increased. More specifically, the rear side surface 304 of the protrusion 302 is bifurcated in a V shape toward the correction unit 96 with respect to the surface of the conveyed paper sheet 32. For example, when the squeegee 301 is branched into a U-shape, the gap (slit-like gap) between the rear side surface 304 of the protrusion 302 and the conveyor belt 100 is narrow, so that the paper sheet 32 that attempts to pass through the gap It is also conceivable that the leading edge collides with the protrusion 302 and the paper sheet 32 is clogged. Therefore, in the present embodiment, the squeegee 301 is bifurcated in a V shape with the rear side surface 304 of the projection 302 toward the correction unit 96 with respect to the surface of the conveyed paper sheet 32. The paper sheets 32 are transported from the central part to the corner part so as to gradually come into contact with the squeegee 301 and are easily guided to the correction part side port 324 (see FIG. 11C).

  Subsequently, as shown in FIGS. 12A and 13A, the paper sheet 32 having the bent or curved deformed portion 32 b that has entered from the air duct side port 323 has a roller 321 and a pulley 103 at the tip. Between the correction part side port 324 and the terminal end to pass through the protrusion 302. In FIGS. 12 and 13, A is shown as the end (rear end edge), and the bent portions are shown as B and C from the end side.

  Subsequently, as shown in FIGS. 12B and 13B, the terminal A (rear edge) of the paper sheet 32 having the bent or curved deformed portion 32 b is connected to the front side surface 303 of the protruding portion 302. Abutting and receiving resistance, the bent or curved portion (deformed portion 32b) is opened as shown in FIGS. 12 (c) and 13 (c). Next, as shown in FIGS. 12D and 13D, the protrusion 302 abuts against the inner side surface (the surface on the space A side shown in FIG. 4) of the bent or curved portion (deformed portion 32b). The bending or bending portion is restricted to open by squeezing the bending or bending portion. Thereafter, the paper sheet 32 tends to pass through a slit-like gap between the rear side surface 304 of the protrusion 302 and the conveying belt 100. As described above, by providing the protrusion 302 on the squeegee 301, even the bent or curved paper sheet 32 can be easily opened.

  In this embodiment, in the squeegee 301 having the protrusion 302, the front side 303 of the protrusion 302 is narrower than the rear side 304, and the rear side 304 of the protrusion 302 is gradually wider. . More specifically, the rear side surface 304 of the protrusion 302 is bifurcated in a V shape toward the correction unit 96 with respect to the surface of the conveyed paper sheet 32. For this reason, as shown in FIG. 13, the paper sheet 32 is gradually squeezed from the center of the paper sheet 32 to the end portion on the long side.

  In this way, the paper sheet 32 that has been conveyed is rubbed so as to be pressed, that is, “squeezed”, for example, even the folded paper sheet 32 is stretched and opened, and then the correction unit At 96, the deformed portion 32b of the paper sheet 32 is completely corrected. Therefore, the deformation of the deformable portion 32b of the paper sheet 32 can be satisfactorily eliminated. Moreover, the paper sheets 32 before and after the correction unit 96 can be prevented from being jammed. Furthermore, the conveyed paper sheets 32 can be stored in the storage unit 98 satisfactorily.

  The shape of the squeegee 301 having the protrusions 302 described so far can be variously changed. Squeegees 301a and 301b shown in FIGS. 14A and 14B are modifications. 14 also shows the state in which the paper sheet 32 is being transported, the end (rear edge) of the paper sheet 32 is in front of the projection 302 of the squeegee 301 in correspondence with FIG. A mode that it contacts the side surface 303 is shown.

  FIG. 14 is an explanatory diagram of the protrusions 302a and 302b when the inclined surface shape (inclination angle) on the air duct side port 302 side is changed. In the protrusion 302 (for example, FIG. 12B) described so far, the front side surface 303 of the protrusion 302 is obtuse with respect to the rear side 304 of the protrusion 302. On the other hand, as shown in FIG. 14A, a projection 302a is formed such that the front side surface 303 is perpendicular to the rear side surface 304. Further, as shown in FIG. 14B, the protrusion 302b is formed such that the front side 303 has an acute angle with respect to the rear side 304. The protrusion 302b has a hook shape or a fishhook shape so as to have a protrusion 305 that enters the bent or curved portion (deformed portion 32b) of the fed paper sheet 32.

  Even when the shape of the protruding portion 302 of the squeegee 301 shown in FIG. 14 is variously changed, the end (rear edge) of the bent paper sheet 32 that has been conveyed receives resistance at the protruding portion 302. Therefore, the bent deformable portion 32b can be opened. In the protrusion 302b having a hook shape or a hook shape, for example, when the paper sheet 32 is strong or the paper sheet 32 is thick, the end of the paper sheet 32 is not formed on the protrusion 302b. Since it is considered that the sheet 32 is caught and clogged, it is more desirable that the inclined angle is an obtuse angle like the protrusion 302.

(Embodiment 2)
In the squeegee 301 shown in the first embodiment, the case where the rear side surface 304 of the projection 302 is bifurcated toward the correction unit 96 has been described. In the squeegee 311 described in this embodiment, a case where the rear side surface 314 of the protruding portion 312 expands in a planar shape toward the correction portion 96 will be described. In both cases of branching and spreading in a planar shape, the concept is the same in that the width of the front side surface of the projection is narrower than that of the rear side, and the width of the rear side surface of the projection is gradually increased.

  FIG. 15 is an exploded perspective view showing a part of the separation part 94b in the present embodiment, and FIG. 16 is a top view showing an exploded part of the separation part 94b. FIG. 17 is a view for explaining the squeegee 311 in the present embodiment, where (a) is a side view and (b) is a top view.

  Similarly to the first embodiment, the separation portion 94b in the present embodiment is also included in the collection device 34 of the paper sheet transport device 20 as shown in FIG. It is provided and separates the paper sheet 32 and the air flow. Since the paper sheets 32 conveyed by the wind pressure of the air flow in the blower tube 22 are completely separated from the air flow, they need to be taken over by another means and sent to the correction unit 96 before that. is there. Therefore, in the separating section 94b, the paper sheets from the terminal end portion (air blow pipe side port 323) to the correction section (correction portion side port 324) of the air blowing tube 22 so that the paper sheets 32 are sandwiched between the roller 321 and the pulley 103. The width of the passage through which 32 passes is gradually narrowed by the conveyance belt 100 and the guide plate 326 (see FIG. 16).

  In the present embodiment, a protruding portion 312 is further provided in the middle of the passage of the separation portion 94b. Specifically, the protrusion 312 is provided by attaching the squeegee 311 to the guide plate 305. By providing the protrusion 312 in the passage in this way, the terminal end (rear edge) of the folded paper sheet 32 abuts against the front side surface 313 of the protrusion 312 and receives resistance, so the deformable portion 32b is opened. Can be in a state (stretched).

  Further, unlike the squeegee 301 of the first embodiment, the rear side surface 314 of the protruding portion 312 that forms the slit-like gap is formed of a flat plate. For this reason, since the area which the surface of the conveyed paper sheet 32 and the conveyance surface (rear side surface 314 of the projection part 312) of the squeegee 311 contact becomes large, the paper sheet 32 can be squeezed more strongly. Further, since the paper sheet 32 is squeezed with the paper sheet that has been folded during the conveyance in the air duct 22 open, the correction unit 96 corrects the deformed part 32b of the paper sheet 32. The deformation of the deformable portion 32b of the paper sheet 32 can be solved satisfactorily. Moreover, the paper sheets 32 before and after the correction unit 96 can be prevented from being jammed. Furthermore, the conveyed paper sheets 32 can be stored in the storage unit 98 satisfactorily.

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