Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a stacking position of paper sheets such as banknotes and slips,
In particular, the present invention relates to a paper sheet stacking device that sends paper sheets between the blades of a rotating impeller to move them to a stacking position, and sequentially discharges and stacks the paper sheets between the blades when reaching the stacking position.

[Prior art and its problems]

In general, an impeller of a paper sheet stacking device has an impeller body and its bases which are planted at predetermined intervals along the outer peripheral edge of the impeller body, and which radiate a spiral toward the outside of the outer peripheral edge of the impeller body. It is composed of a large number of arc-shaped blades that spread in a circular shape, and in particular, adjacent blades are in a relationship of gradually approaching each other toward the center side in the radial direction of the impeller body, and at the innermost position between the blades, The distance between the inner surface of the blade and the outer surface of the next blade base is such that one sheet can sandwich it. Then, at the exit of the transport path that picks up and conveys the paper sheets, the paper sheets are sent to the innermost position between the blades by using the conveying force applied to the paper sheets, and the leading end portion of the paper sheet is conveyed to the blade. The inner surface and the outer surface of the next blade base are sandwiched and moved to the stacking position.

In this way, the holding of the paper sheets between the blades during the movement to the stacking position is performed only by the sandwiching between the inner surface of the blade and the outer surface of the next blade base. However, when the paper sheets are inserted between the blades, the paper sheets are not always inserted to the innermost position between the blades, and the paper sheets that are not inserted to the innermost position are the paper sheets before reaching the stacking position. The buoyancy of the leaves causes the leaves to escape from between the blades, resulting in defective accumulation.

In order to prevent this, when the exit of the transport path is located near the outer circumference of the blade of the impeller and the paper sheet is inserted to the innermost position between the blades, the leading edge of the paper sheet is inserted to the innermost position. However, more than half of the trailing edge area of the paper sheet is in the conveyance path, and a strong conveyance force is applied to the paper sheet in the insertion direction between the blades. The leaves will be clogged between the feathers. If the transport path outlet is located near the outer circumference of the blade of the impeller within the range where such clogging does not occur, the trailing edge of the paper sheet received between the blades will exit the transport path outlet and will be obstructed by the transport path outlet. It stagnates at the road exit or is deformed to the side of the trailing blade, and the next sheet cannot be fed between the blades, causing clogging of the sheet. In this way, the exit of the transport path for sandwiching and transporting the paper sheets has to keep a predetermined distance from the outer circumference of the blade of the impeller.

On the other hand, even if a paper sheet is inserted at the innermost position between the blades, its holding force is very weak because it can accept the insertion of the paper sheet, and the outer edge of the blade faces downward. That is, in the state where the leading edge of the sandwiched paper sheet faces upward and the rear end of the paper sheet, which is a free end, faces downward, the paper sheet comes out from between the blades and falls downward.

Therefore, in the conventional paper sheet stacking apparatus, all the paper sheets are sent out obliquely downward from the exit of the conveying path, and the impeller has its shaft supported horizontally so that the blades are positioned obliquely below the exit of the conveying path. The stacking position is provided near the lower part of the impeller.

By arranging the transport path outlet, the impeller, the stacking position, and the locking member at such a relational position, it is possible to transfer the paper sheets between the blades with the leading ends of the paper sheets always facing downward. The paper sheet is locked and accumulated by the locking member to prevent the paper sheet from slipping out from between the blades.

However, even with this conventional device, there is the first drawback that the paper sheet still escapes from between the blades due to the structure of the impeller described above.

On the other hand, if the positional relationship is fixed in this way, for example, to the paper sheet counting machine that accumulates the paper sheets that are counted and conveyed, the banknote payer, the banknote deposit machine, the banknote changer, etc. When incorporating a paper sheet stacking device, the layout and space of the entire machine are restricted, and as a result, the entire machine must be unnecessarily increased in size. If is the paper sheet take-out port of the machine operator, there is a second drawback that the take-out port position can be provided only at a fixed position below the machine.

Further, in the conventional device, due to the structure of the above-mentioned impeller, the transport mode of the transport path is a horizontal transport system (one surface of the paper sheet faces downward,
Applicable only to stacking paper sheets that are sent out from the transport path with the other side facing up), and the vertical transport method (one edge in the widthwise direction of transport of paper sheets is downward, and the other edge is upward) The third drawback is that it cannot be applied to the stacking of paper sheets sent out from the transport path of (1).

In addition, in the conventional device, the waist of paper sheets, etc. with a small feeding size between the blades (the paper surface does not become straight in the feeding direction to the blade, but is bent and distorted in the middle) )
Although it is possible to accumulate paper sheets that are difficult to stack, there is a fourth drawback that paper sheets that are easily broken, such as paper sheets that have a large dimension in the feeding direction, cannot be collected. For example, in the case of stacking banknotes, the conventional apparatus is designed to send banknotes between the blades in the width direction and stack the banknotes, and cannot stack the banknotes in the longitudinal direction. This is because when feeding a bill in the longitudinal direction, the distance between the exit of the conveying path and the outer peripheral edge of the blade of the impeller becomes very large, a waist break occurs at the time of feeding, and the bill is inserted into the innermost position between the blades. Instead, the banknotes slipped out from between the blades while moving to the stacking position, and the banknotes that were bent at the waist were jammed between the blades, and the jammed banknote trailing edge was conveyed between the blades for the next banknote insertion, This is because the road outlet is blocked and a bill jam or the like is generated when the next bill is not inserted between the blades. Further, even in the case of the banknotes fed in the width direction between the blades, in the case of the banknotes that are exhausted due to circulation, the banknotes are likely to be bent and similar banknote jams occur.

[Object of the Invention]

Further, a guide piece having a width similar to that of the belt 19 is provided on the extension line of the guide belt 19 in the traveling direction as it approaches the pulley 18.
20 is provided, and this guide piece 20 is a surface on the left side in FIG.
20a is an edge-shaped guide surface, and holds rib formation at the rib formation portion of the paper sheet and blades 14b, 14b at the rib formation portion.
It is a guide for feeding into the space. Therefore, the guide surface 20a is located on the same plane as the outer surface of the belt 19 and is linear, but the starting end side portion of the guide surface 20a approaching the pulley 18 is an arc shape receding from the plane. There is. This arc-shaped portion has a role of contacting and guiding the tip of the paper sheet that has passed through the guide belt 19 that is going to move to the pulley 18 side, and guiding the tip of the paper sheet to the linear guide surface 20a portion. do. An end portion 20b on the front side (downward in FIG. 1) of the guide piece 20 intersects with a circumscribing circle of the blades 14b, 14b, ... Until the blade 14b passes through the guide piece 20, the end portion 20b leaves the blade 14b. By pressing it, the space between the front blade 14b and the front blade 14b is widened to facilitate the insertion of the leading edge of the paper sheet between the blades 14b, 14b. In addition, the blade 14b that has passed through this end portion 20b has no load and is rapidly restored to its original shape.
The crossing time between the outer peripheral edge of the blade 14b and the guide surface 20a of the guide piece 20 is a minute time, and even when the leading edge of the paper sheet is inserted between the blades 14b and 14b during the crossing, the leading edge of the paper sheet Prevents paper sheets from being jammed by being caught in the outer peripheral edge of the blade 14b and causing jamming. In order to insert the inter-blade insertion ribs into the blades 14b and 14b, the pulleys 16 and 18, the belt 19 and the guide piece 20 are attached to the blades 14b and 14b.

The formation site is directed to the guide surface 20a of the guide piece 20, and the paper sheet having the rib shape is inserted between the blades 14b and 14b. Note that the rib shape of the paper sheet may gradually disappear as it exits the outlet 13 of the transport path 1. Even with such a paper sheet, the ribs are formed at the same portion by the ring belts 25, 25, the guide belt 19, and the guide piece 20. Will be reformed. Further, since the ring belts 25, 25 are pushed by the paper sheets and advance toward the blade 14b as described above, the trailing ends of the paper sheets inserted between the blades 14b, 14b are very long for the ring belt. Held by 25,25, blades 14b, 14b

Locking members 35, 35 are provided at the stacking position 34. These locking members 35, 35 are locking portions 35a, 35a for locking the tips of the paper sheets between the blades 14b, 14b of the impeller 14 and discharging the paper sheets between the blades 14b, 14b, A stacking restricting part which is provided following the locking parts 35a and 35a and which controls the leading end and guides in the stacking direction in order to stack and stack the discharged paper sheets.
35b and 35b. In particular, the respective locking portions 35a, 35a are located between the impeller 14 and the respective rotating bodies 33, 33 as shown in the second illustration, and the moving areas of the respective blades 14b, 14b ... As shown in the first illustration. The ends of the blades intersect each other and project inward in the radial direction from the outer peripheral surface of the impeller body 14a.

Therefore, the leading end of the paper sheet inserted up to the blade bases 14b ₁ , 14b _1, ..., Especially near the rib forming portion for holding the paper sheet, is the locking portion 35.
As a result, it comes into contact with a and 35a, and the paper sheet is ejected without bending the waist.

In addition, at the stacking position 34, a paper sheet trailing end guide 36 is provided upright at a distance from the locking member 35 at a distance slightly larger than the length of the paper sheet in the feeding direction, and a paper sheet integrally formed with the guide 36. A bottom plate 37 that guides the lower edge of the leaf (side edge in the feeding direction of the paper sheet), a pressing plate 40 that is urged by a tension spring 39 from one surface of the accumulated paper sheet toward the impeller 14 and can move in the accumulation direction. Is provided.

Further, the stacking position 34 starts from the position immediately before reaching the stacking position 34.
It has a disc 42 that is provided over the entire surface and is rotated by a shaft 41. The upper surface of the disc 42 is located on the same horizontal plane as the upper surface of the bottom plate 37, and is located on a plane slightly below the lower edge of the paper sheet held and moved between the blades 14b and 14b of the impeller 14. To be done. The function of the disc 42 is released when the tips of the paper sheets held and moved between the blades 14b and 14b are locked by the locking portions 35a and 35a. As a result, the paper sheets have feathers 14b, 14
It falls off from b. At this time, the bottom plate 37 of the lower end of the paper sheet receives the lower edge of the paper sheet and maintains the standing posture of the discharged paper sheet. On the other hand, the rear end portion of the paper sheet moves to the stacking position 34 because it is held while being held in the arc shape of the blade 14b when the paper sheet holding between the blades 14b and 14b is released. However, it is in the left position in FIG. 1, that is, in the upper left portion of the upper surface of the disc 42. When the holding of the paper sheets is released, the lower edge of the trailing end portion of the paper sheets falls off downward, but the lower edge is supported by the disc 42 and the paper sheets are kept in the standing posture. At that time, the disk 42 is an impeller
It is rotated in the direction of the arrow at a peripheral velocity substantially the same as the velocity ν _{2 of} 14, and the rear end portion of the paper sheet is moved so as to be aligned with the surface of the accumulated paper sheet. The upper right area of FIG. 1 on the upper surface of the disc 42 serves as a guide when the stacked paper sheets are moved to the right in accompaniment with the stacking operation. In this example, the disc 42 is used not only for moving the trailing edge of the paper sheet to the stacking position 34 but also for guiding the stacking paper sheet, but is provided immediately before the stacking position to perform only the former role. You may do it.

Next, the operation of the above embodiment will be described.

First, the operation of inserting paper sheets between the blades will be described.
3 (a), reaches the distal outlet 13 of the paper sheet S ₃ which has been conveyed in a conveying path 1 in the (a-1), (a -2), the conveyor belt 7,7,12, The central part is the guide belt for both sides l ₁ of the conveyance width of the paper on the conveyance path defined by 12.
It is pushed to the left by 19 and the pulley 16 to form a blade-insertion rib (note that l ₂ indicates the most protruding line of the rib).
Then, as the ribs escape from the outlet 13, the ribs are also sequentially formed on the subsequent portions of the paper sheets, and the right side surface of the rib portion is fed to the outer surface of the guide belt 19 and sent out from the outlet 13. Both side portions of the rib forming portion at the tip of the paper sheet S ₃ come into contact with the ring belts 25, 25 and push the ring belts 25 in the traveling direction. The ring belts 25, 25 are pushed to move the paper sheets S ₃
Is deformed in the traveling direction of the paper and moves along with it, and the paper sheet S ₃ is rotated by the rotation of the ring belt itself and the restoring force to the original shape.
On the left side of the sheet and press both sides of the rib forming portion on the paper surface to the right to guide the rib forming portion to the guide belt 19
Then, the rib shape is maintained. When the tip of the paper sheet S ₃ advances to the guide surface 20a of the guide piece 20, the ring belts 25, 25 also press the ribs on both sides of the paper sheet surface as shown in FIG. 3 (b). While continuing to move to both sides of the guide piece 20, the rib forming portion of the paper sheet is moved to the guide piece 20.
To contact with. On the other hand, the ring belts 25, 25 are rotated about their own axes to impart a conveying force to the paper sheets, and this rotation causes the ring belts 25, 25 to rotate in the third direction relative to the pulleys 22, 22.
In the figure (b), the bulging portion is formed in the upper portion by the restoring force to restore the original shape, and both side portions of the succeeding portion of the paper sheet S3 are pressed to the right through the bulging portion of the ring belts 25, 25, The pressing contact of the subsequent rib forming portion with the guide belt 19 is continued. While the tip of this paper sheet S ₃ is advancing along the guide surface 20a, one of the blades 14b of the impeller 14 that is rotating and moving is disengaged from the end 20b and rapidly restored to its original shape. with sufficient clearance for insertion of the paper sheet S ₃ tip between 14b and the guide surface 20a is formed, the gap is gradually larger with the rotation of the impeller 14, also the blade in the rotational direction next order The rotation of the impeller 14 locks 14b to the end 20b.
At that time, the rib forming portion between the blades at the tip of the paper sheet passes through the guide surface 20a and is inserted between both blades 14b, 14b. The trailing edge of the paper sheet S ₃ is still in the transport path 1 and the transport speed ν ₃ in the transport path 1 is given, and the ring belt 25 and the guide are provided at the intermediate portion of the paper sheet S _{3 in} the feeding direction. Belt 19
Gives a speed ν _{4 that} is slightly faster than the speed ν ₃ ,
The paper sheet S ₃ moves approximately at ν between the blades 14b, 14b moving at the velocity ν _2.
Go at a speed of ₃ .

The tip of the paper sheet S ₃ is at the base 1 of the blade 14b as shown in FIG. 3 (c).
When it advances to the vicinity of 4b ₁ , it first comes into contact with the peripheral surface of each rotating body 33, and at that time, the rear end of the paper sheet S ₃ is still ring belt 25, 25.
Since it is held between the guide belt 19 and the guide piece 20 and the leading edge of the paper sheet S ₃ is kept pressed against the outer peripheral surface of each of the rotating bodies 33, 33, the rotating body 33. , 33 is fed to the base portion 14b ₁ of the blade 14b at the front in the rotational direction at a velocity ν ₁ . By this feeding, the tip portion of the interleaf blade insertion rib forming portion of the paper sheet S ₃ is pushed in the direction of the shaft 26 by the inner surface 14b ₀ of the blade 14b that is the front in the rotation direction, and both side portions thereof are the respective rotating bodies 33, A paper sheet holding rib that is pressed outward in the radial direction by the outer peripheral surface of 33 and projects toward the axis 26 of the impeller 14 for the paper sheet S ₃ (see the paper sheet S _{2 in} FIG. 3A). ) Begins to form. Then, as the impeller 14 continues to rotate, the trailing portion of the paper sheet S _{3 in} the feed direction is the arc-shaped inner surface 14b of the blade 14b that is in the front in the rotational direction.
_A paper sheet holding rib is formed on the entire area of the paper sheet S ₃ that contacts the inner surface 14b ₀ of the blade 14b of the paper sheet S ₃ . By the formation of the ribs for holding the paper sheets, the inter-blade insertion ribs formed at the same position will be erased.
At that time, the rear end portion of S ₃ has passed through the outlet 13 of the conveyance path 1 to the position of the pulley 18 as shown in FIG. 3 (c), and is guided by the guide belt 19, the guide piece 20, and the belt ring.
By 25, the formation of the inter-blade insertion rib is still continued at the rear end portion of the paper sheet S ₃ . At that time, the portion of the paper sheet S ₃ that is in contact with the blade inner surface 14b ₀ is moved at the peripheral speed ν ₂ of the impeller 14, so that the rear end portion of the paper sheet S ₃ also advances at that speed. Slip occurs between the rear end portion of the leaf S ₃ and the ring belts 25, 25 and the guide belt 19 due to the speed difference. However, since the ring belts 25, 25 are used, the slip force is reduced by the elastic deformation and the speed ν _{4 of the} ring belts 25, 25 and the guide belt 19 is increased.
Some percentage of this is added to the rear end portion of the paper sheet S _{3, and} the interleaf blade insertion rib formed in the subsequent portion and the paper sheet holding rib formed in the front end side portion thereof The insertion force in the direction of the blade base 14b ₁ and the pressure contact force to the blade inner surface 14b _{0 are applied} to the entire S ₃ to more securely hold the paper sheet between the blades 14b and 14b. In FIG. 3 (d), when the trailing edge of the paper sheet S ₃ advances to the guide surface 20a of the guide piece 20, the portion above the pulley 22 of the ring belts 25, 25 is gradually circular due to rotation and original shape restoring force. The paper sheet S ₃ is restored to its shape.
Changes from the contact state with one surface to the contact state with the rear edge,
While maintaining the contact state, set the rear edge of the paper sheet S ₃ to the guide surface.
Prevention is moved away to the left from 20a, the next paper sheet S ₄ the blade 14b, the rear end portion of the paper sheet S ₃ when it is inserted into between 14b their wings 14b, and to block the inter-14b To do. At that time, the leading edge of the next sheet S ₄ has reached the exit 13 of the transport path 1,
Formation of ribs for insertion between blades has started. As shown in FIG. 3 (d), the trailing edge of the paper sheet S ₃ is the ring belt 25, 25.
By the way, the ribs for inserting blades at the rear end portion of the paper sheet S ₃ start to disappear while being separated from the guide surface 20a to the left, but the ring belts 25, 25 are restored to a substantially circular shape and the paper sheets are restored. S
₃ is located on the right side of the rear end portion, and finally the rear edge is flipped to the left to restore the circular shape shown in FIG. 3 (a).

Next, the movement of the paper sheets inserted between the blades to the stacking position 34, and the discharging and stacking operation will be described.

In FIG. 3 (a), the paper sheet S ₂ whose rear end is repelled by the ring belt 25 has a diameter difference and a peripheral speed difference between the outer peripheral surface of each of the rotating bodies 33, 33 and the blade base portion 14b _1. Accordingly, the insertion state into the blade root 14b ₁ of the tip is maintained, also integrated position through the paper sheet S ₁ is positioned by the rotation of the paper rib shape of sheets holding rib is held untilゝimpeller 14 34 Paper sheets S ₀ position.
Then the paper sheet S ₀ (for convenience S ₀ of described paper sheet) of the tip engaging portion 35a of the locking member 35 abuts against the 35a,
The paper sheet S ₀ only falls off from the blades 14b, 14b, but the paper sheet S ₀
The bottom edge of the leading edge is supported by the bottom plate 37, and the bottom edge of the trailing edge of the paper sheet S ₀ is a disc.
It is supported by the upper surface of 42 and kept in an upright position. When the impeller 14 further rotates, the paper sheet S ₀ releases contact with the inner surface 14b ₀ of the blade in the front of the rotation direction and the outer surface of the blade 14b next in the rotation direction of the sheet S ₀ as shown in FIG. 3B. in contact with the surface of the sheet S ₀ is moved toward the rotational direction, the paper sheet S ₀ tip engaging portion 35
It is moved toward the stacking direction of the paper sheets while being swirled by the a and 35a, and comes into contact with the stacking restricting portions 35b and 35b as shown in FIGS. 3 (c) and 3 (d). On the other hand the rear end of the paper sheet S _0, the third view (b), (c), (d) by the upper surface of the disc 42 to urchin rotation shown of the paper sheet S ₀ distal locking portion 35a, 35a The paper sheet S is moved in the direction toward the rearward direction and the movement in the paper sheet stacking direction along the paper sheet rear end guide 36 is performed, and the paper sheet S ₀ is stacked.

The above description is for the case of stacking paper sheets having the same length in the paper feed direction, but it is also possible to stack paper sheets having different lengths in the paper feed direction in a mixed state. . In that case, when the leading edge of the longest paper sheet is inserted into the blade base portion 14b ₁ , the trailing edge of the paper sheet passes through the outlet 13 of the transport path 1 in a dimensional relationship such that the outlet 13 of the transport path 1 and the impeller 14 and should be provided. In this case, a paper sheet having a length shorter than the above-mentioned paper sheet will have its rear end escape from the outlet 13 of the transport path 1 by the time the leading end reaches the blade base 14b ₁ , but the ring belts 25, 2
By means of 5, the guide belt 19 and the guide piece 20, the paper sheets are prevented from slipping out between the blades 14b, 14b, and a conveying force is applied to the paper sheets in the direction of the blade base 14b ₁ . Therefore, regardless of the length of the paper sheet, the paper sheet is surely fed to the blade base 14b ₁ , the rib for holding the paper sheet is also surely formed, and it is surely held between the blades 14b and 14b and the accumulation position 34.
Will be transported to.

Next, another embodiment of the present invention will be described with reference to FIGS. In this embodiment, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

To do. That is, the conveyor belt 1 in this embodiment plays the role of the rotating bodies 33, 33 of the first embodiment. The outer peripheral surfaces of the rotating bodies 33, 33 in this example may be radially outside or radially inside of the blade base portion 14b ₁ .

Further, in this example, the rib forming means 15 for forming the inter-blade insertion rib on the paper sheet is different from that of the first embodiment. In this example, a pulley 44 rotatably supported is provided at the center of the shaft 3 of the pulleys 5, 5 positioned just before the outlet 13 (position of the pulleys 10, 10) of the transport path 1 and provided at the shaft 45. The pressing belt 49 is hung between the pulley 46 and the pulley 48 of the shaft 47, and the ring belt 50 is sandwiched between the outer surface of the belt 49 and the pulley 44.
The part located on the left side of the figure is the conveyance road surface (conveyor belts 7,7,1
It is projected to the left from the surface contact part of 2,12). This ring belt 50 is a blade 14b with respect to the widthwise direction of feeding of paper sheets.

Further, the rotation speed of the outer circumference of the ring belt 50 is rotated at a speed slightly higher than that of the conveyor belts 7, 7 through the driven rotation shaft 45, the pulley 46, and the pressing belt 49. The pulleys 10 and 10 located at the exit 13 of the transport path 1 around which the transport belts 12 and 12 are wound
On the other hand, the pulleys 11 and 11 are located slightly above in FIG. 4, and the portions of the conveyor belts 12 and 12 located between the pulleys 10, 10, 11 and 11 pass through the outlet 13 of the conveyor path 1. It functions to move the trailing edge of the paper sheets to the left in FIG.

Next, the operation will be described.

Figure 6 (a), (a-1 ), (a-2) at the leading end of the paper sheet S ₃ conveyed to the conveying path 1 approaches the pulleys 5,5 of the outlet 13 located just before, that The tip first comes into contact with the ring belt 50 and pushes the ring belt 50 toward the outlet 13. On the other hand, the ring belt 50 is rotating, and the upper half of FIG. 6 (a) is gradually swollen with respect to the pulleys 5 and 5 and is placed on one surface of the paper sheet S ₃ , and the center of the paper sheet in the conveyance width direction. The portion is pushed to the left in FIG. 6 (a) to form ribs for inserting between blades. According tip of the paper sheet S ₃ to escape outlet 13 (pulley 10, 10 position), the rib for insertion between vanes also continues formed subsequent portion of the paper sheet S _3, the paper sheet S ₃ The tip of the rib forming portion for inserting between blades is inserted between the blades 14b, 14b (see FIG. 6 (b)). At that time, the conveyance belts 7 and 7 guide both sides in the feeding width direction of the rib forming portion of the paper sheet S ₃ . The paper sheet S _{3 that} has entered between the blades 14b, 14b first comes into contact with the inner surface 14b ₀ of the blade 14b at the front in the rotational direction at the tip of the rib forming portion, and advances toward the base 14b _{1 of the} blade 14b. At that time, the conveyor belts 7, 7 whose front ends on both sides in the feeding width direction with respect to the rib forming portion of the paper sheet S ₃ are located on the peripheral edges of the rotating bodies 33, 33
Re-contact the outer surface and move on it. Because it base 14b ₁ of the blade 14b with respect to is positioned radially inner diameter side, the blade between the insertion rib forming portion leading end of the paper sheet S ₃ is further moved toward its base 14b _1, for insertion between the wings At the same time as the rib is erased, a rib for holding a paper sheet, which protrudes in the direction opposite to the rib, that is, in the direction of the shaft 26, begins to be formed. Not escape exit 13 of the rear first transport path 1 of the paper sheet S ₃ at that time, the blade 14b to the paper sheet S _3, insertion conveying force has been applied to between 14b, vanes The insertion force to the blade base 14b _{1 is applied} to the entire paper sheet through the inter-insertion ribs, and the transfer force is also applied to the outer surface portions of the transfer belts 7 and 7 located on the outer peripheral surfaces of the rotating bodies 33 and 33. since it is, the subsequent portion of the paper sheet S ₃ in close contact with the vane inner surface 14b ₀ whole area of the rotation direction front position, the paper sheet S ₃ is paper in the blade inner surface 14b ₀ contact zone whole along its arcuate shape A rib for holding the class is formed. Immediately after that, the paper sheets
The rear end of S ₃ escapes from the exit 13 (the position of the pulleys 10 and 10) of the transport path 1 (see FIG. 6 (c)). At that time, the ring belt 50 is almost restored to the original shape of a circle, but a part thereof (the lower end portion of FIG. 6C) comes into contact with the rear edge of the paper sheet S ₃ , and the pulley is attached to the rear edge thereof. Apply pressing force to the 10 and 10 side. As a result, the trailing edge of the paper sheet S ₃ is the conveyor belt 1
It is moved along the outer surfaces of the pulleys 2, 12 and is displaced to the surface of the conveyor belt 12, 12 between the pulleys 10, 10, 11, 11 as shown in FIG. At that time, the ring belt 50 is restored to the original circular shape, but the next paper sheet S ₄ is in a contact start state with the ring belt 50. When this paper sheet S ₄ advances to the paper sheet S ₃ position shown in FIG. 6 (a), the preceding paper sheet S ₃ moves to the paper sheet S ₂ position shown in FIG. 6 (a). After moving, the rear end of the paper sheet S ₃ is repelled to the left by the conveyor belts 12, 12. Thereafter, the paper sheet S ₃ is held between the blades 14b and 14b by the paper sheet holding rib and moved to the stacking position 34. The integration operation is the same as that of the first embodiment, and will not be repeated. In this example, the trailing ends of the paper sheets inserted between the blades 14b and 14b are moved leftward in FIG. 6 (d) by the ring belt 50, the pulleys 10 and 10 and the conveying belts 12 and 12, and the conveying path 1 The rear end of the paper sheet does not close the outlet 13 of the paper sheet, and the rear end of the preceding paper sheet closes the outlet 13 when the next paper sheet is inserted between the blades 14b and 14b. Prevents paper jams.

In this embodiment, the conveyor belts 7, 7 are commonly used as the paper sheet feeding belt for forming the paper sheet holding ribs. However, the conveyor belts 7,7 are limited to the pulleys 5,5,4,4 as shown in the example of FIG.
Pulleys for each starting end are provided on both sides of 5,5, and each rotating body 33, 33 is positioned at the feed width direction position corresponding to those pulleys, for feeding each paper sheet between each starting end pulley and each rotating body 33. The belts may be wound individually.

In both of the above-mentioned embodiments, one impeller is provided with pulleys, rotating bodies, paper sheet feeding belts, etc., as examples of pressing means, provided on both sides thereof, and the number is two.
An example in which there are two impellers and pulleys as pressing means are provided on both sides of each impeller for a total of four, two on each side of each impeller, and one between each impeller for a total of three. May be an example. Also, although an example of the vertical transportation system is shown, it is needless to say that it can be applied to the horizontal transportation system, in which case, for example, FIGS. 1 and 4 are side views, FIG. 2 and FIG. 5 are front views. It is said that. In addition, both examples have been described with respect to stacking paper sheets in the longitudinal feed direction, but it goes without saying that the invention can also be applied to paper sheets in the short-side feed direction, and depending on the length of the paper feed direction, the exit of the conveyance path The distance between the blade and the outer circumference of the impeller may be set appropriately. It should be noted that the rib forming means 15 is not required to be provided when the waist does not break, such as a strong paper sheet or a paper sheet having a short feeding direction length. Further, in the embodiment shown in Table 1, as the rib forming means 15, at the outlet 13 of the conveying path 1, the pulleys 10, 10, 5, 5, each conveying belt 12, 12, 7, 7, pulley 6, guide belt 19, outlet A guide belt 19, a guide piece 20, and ring belts 25, 25 are provided in the subsequent stage of 13. However, it goes without saying that only one of the rib forming means 15 may be installed.
If the rib forming means 15 is provided only on 13, the guide belt
It is preferable to remove 19 and use the pulley 16 as a roller. The protruding direction of the inter-blade insertion rib is opposite to the protruding direction of the paper sheet holding rib. This is paper leaf inside
This is to make it easier to insert along the circular surface of 14b ₀ .
The protruding directions of both ribs may be the same direction. Also the transport path 1
Although the paper sheet clasping carrier of is shown as an example of the transport belts 7, 7, 12, and 12, it is also possible to use a roller group configuration for sandwiching and transporting both sides of the paper sheet, or a combination configuration of the transport belt and the roller group. Good.
Further, the impeller 14 and the rotating bodies 33, 33 may be integrally formed, and the impeller body 14a of the impeller 14 and the blades 14b ... 14b may be integrally formed.
