The above-mentioned dividing means comprises a gate 11 rotatably supported about the shaft 10 of the above-mentioned pulley 20. The gate 11 has a guide surface 11a on the distal end side thereof, and receives the shaft 1 based on the front / back discrimination signal from the discrimination unit 1 described above.
It rotates to the solid line position or the two-dot chain line position shown in the figure around 0. When rotating to the position shown by the solid line, the first transport path is communicated with the second transport path and the third transport path. The above-mentioned reversing means is provided between the second conveyance path and the third conveyance path, and floats the back-facing sheets for reversing from the above-mentioned second conveyance path to smoothly carry in and out. The guide frame 12 includes a carry-in guide frame 12, a carry-out guide 13, and an entrance stop member 14 provided on the guide frames 12, 13. The above-mentioned guide means comprises a guide roller 15 disposed on a shaft of a pulley 27, and a single or radially plural sheet pressing member is provided on the outer peripheral surface of the guide roller 15. A tooth-like projection 17 is provided.
The outer diameter of the projection 17 is determined by the pulley 27 and the conveyor belt 8.

Next, the transport operation of this embodiment will be described. The paper sheets delivered from the outlet 4 of the discriminating section 1 are clamped by the transport belts 5 and 6 and transported to the gate 11. Here, in the case of the paper sheet determined to be a table by the discriminating unit 1, the gate 11 is rotated counterclockwise around the shaft 10 by a driving source (not shown) to a position indicated by a two-dot chain line in FIG. To rotate. Therefore, the front-facing sheet is conveyed to the holding portion of the conveying belts 5, 7 and then conveyed to the merging guide 16, where it is pinched by the conveying belts 5, 9 and discharged downward. It can be conveyed in the direction of the section. Next, in the case of the paper sheet determined to be the back side by the discriminating section 1, the gate 11 is rotated clockwise around the shaft 10 to a position shown by a solid line in FIG. To rotate. Therefore, the back-facing sheets are separated from the front-facing sheets by the gate 11 and conveyed by the conveying belts 6 and 8 to be carried in.

The sheet is carried into the reversing unit for reversing the sheet by the interaction of. In the above-mentioned reversing section, paper sheets are reversed by the following operation. This inversion operation will be described with reference to FIGS. FIG. 3 shows a front end 3 of the paper sheet when the paper sheet enters a space defined by the carry-in guide frame 12 and the carry-out guide frame 13.
3 and the state of the front end 33a. Than the outer diameter when the conveyor belt 8 is wound around the pulley 27,
Since the outer diameter of the protrusion 17 provided on the outer peripheral surface of the guide roller 15 is configured to be larger, the paper sheet receives a forced deformation force and is pressed against the transport belt 6. The amount of deformation at this time is regulated by the carry-in guide frame 12, and
Since the front end 33 of the paper sheet is forcibly deformed, the rigidity of the paper sheet apparently increases, and the paper sheet smoothly advances into the guide frames 12 and 13, and finally reaches the approach stop member 14. It collides and stops (see FIG. 4). At this time, the rear end 34 of the sheet is disposed such that the distance between the outer peripheral surface of the guide roller 15 and the stop member 14 is substantially equal to the length of the sheet in the conveying direction. Therefore, the protrusion 17 provided on the outer peripheral surface of the guide roller 15
With the rotation of, it moves from a thick solid line to a thick two-dot chain line and is pressed against the conveyor belt 9. Next, as shown in FIG. 5, the paper sheets are sandwiched between a plurality of rotating members including a plurality of pulleys 27 and a pulley 30, and transport belts 8, 9 constituting a part of a third transport path. And the rear end 34 of the paper sheet and the rear end 34
a becomes the state of FIG. That is, the rear end 3 of the paper sheet
4 receives a forced deformation force and is pressed against the conveyor belt 9. The amount of deformation at this time is regulated by the carry-out guide frame 13, and the rear end 34 of the paper sheet is forcibly deformed, so that the rigidity of the paper sheet becomes apparently large, and the paper sheet becomes smooth. Can enter the conveyance path clamped by the conveyance belts 8 and 9. Thereafter, the sheet is conveyed along the merging guide 16 shown in FIG. 1, reaches the holding portion of the conveying belts 9 and 5, and is conveyed downward. Therefore, the paper sheets sandwiched by the transport belts 5 and 9 and conveyed downward are all conveyed as front paper sheets in the same direction as the front paper sheets. Further, the transfer belts 5, 7
And the transfer time from the gate 11 to the holding portions of the conveyor belts 5 and 9 and the gate 11 through the holding portions of the conveyor belts 6 and 8 and after the reversing operation of the paper sheets, the conveyor belt The transport path length and transport speed of each transport path are set so that the transport time including the reversal time up to the holding portions 5 and 9 becomes substantially equal. Therefore, only the paper sheets determined to be face-down by the discriminating unit 1 are sorted by the gate 11, and turned upside down in the above-mentioned conveyance path, and are conveyed to the post-processing unit by the conveyance belts 5 and 9. There is no variation in the interval between the two, and there is no inconvenience in processing. Next, the skew correcting operation when the backward skewed sheets are conveyed will be described with reference to FIGS. In FIG. 4, the skewed sheets are the guide frame 1.
When transported into the inside 2, 13, the leading portion collides with the approach stop member 14 first, and the following portion collides with the approach stop member 14 with a delay. At the same time as the leading ends of the paper sheet collide with the approach stop member 14, the trailing ends 34 are separated from the holding portions of the conveyor belts 6, 8, and are projected by the projections 17 provided on the outer peripheral portion of the guide roller 15. The conveying force of the rear end portion and the knocking action act on the paper sheet. At this time, since the conveying force is slightly applied only to the trailing portion of the skewed sheet, the skew of the sheet is corrected while shifting in the direction perpendicular to the drawing. FIG. 6 shows the operation of the reversing section when the reversing sheet attempts to enter the reversing section following the reversing sheet in the embodiment shown in FIGS. Is shown. The guide roller 15 presses the front end 33 of the paper sheet that is about to enter the reversing section against the conveyance belt 6 and completes the entry to the reversing section at the same time, and moves the rear end 34 of the paper sheet that is about to be reversed to the conveyance belt 9. Since it has a pressing action, even if two or more sheets enter the reversing section continuously in a state of approaching each other, the reversing operation can be performed without causing any trouble such as a jam. Next, FIG. 7 shows the embodiment shown in FIG.
Non-reversed paper sheets whose length in the transport direction is abnormally short,
For example, a state in which the folded paper sheet 38 is transported through the gate 11 when the folded paper sheet 38 enters the first transport path is shown.
Such a paper sheet 38 usually causes a defect in the post-processing unit, and is removed before reaching the post-processing unit by a sorting unit (not shown). However, as shown in FIG. 7, by making the distance between the end point of clamping by the conveyor belts 5 and 6 and the starting point of clamping by the conveyor belts 5 and 7 sufficiently small, the length in the conveying direction is abnormally short. Paper sheets can also be smoothly transported. In the illustrated embodiment described above, the manner of winding the belts constituting each transport path is not limited to the illustrated example, and the feeding direction and length of the paper sheet may vary depending on the size of the paper sheet to be handled. It goes without saying that the design can be appropriately changed according to the properties and the like. The position, number and the like of the guide rollers 15 can be selected arbitrarily according to the properties of the paper sheets to be handled. Further, the projection 17 provided on the outer peripheral surface of the guide roller 15 is not limited to the shape as in the above-described embodiment. For example, FIG.
Various shapes as shown in (b) and (c) are conceivable.
Even with such a shape, the functions and operations are the same as those of the above-described embodiment. Next, another example of the sheet processing apparatus of the present invention will be described with reference to FIGS. In the embodiment shown in FIG. 9, one or a plurality of brush members 47 made of a flexible member, for example, a thin line of nylon or the like are used as a sheet pressing member instead of the guide roller 15 as the guiding means shown in FIG. A guide roller 45 is provided, and the other components are the same as those shown in FIG. The guide roller 45 is configured such that the distance between the outer peripheral surface of the guide roller 45 and the entry stop member 14 is slightly longer than the length of the back-facing paper sheet in the transport direction. The brush member 47 provided on the outer peripheral surface of the guide roller 45 has an outer peripheral diameter that is slightly larger than the outer peripheral diameter of the portion where the conveyor belt 8 is wound around the pulley 27, and furthermore, the outer peripheral surface and the entry stop member. The distance 14 is slightly shorter than the length of the back-facing paper sheet in the transport direction. Next, in the embodiment shown in FIG.
The reversing operation of the paper sheet determined to be the back will be described with reference to FIGS. FIG. 10 shows a state of the front end 33 and the front end 33a of the paper sheet when the paper sheet enters the space defined by the carry-in guide frame 12 and the carry-out guide frame 13. Since the outer diameter of the brush member 47 provided on the outer peripheral surface of the guide roller 45 is larger than the outer diameter when the conveyance belt 8 is wound around the pulley 27, the paper sheets are It receives the forced deformation force and is pressed against the conveyor belt 6. The amount of deformation at this time is regulated by the carry-in guide frame 12, and since the front end 23 of the paper sheet is forcibly deformed, the rigidity of the paper sheet becomes apparently large, and the paper sheet The vehicle smoothly advances through the guide frames 12 and 13 and finally collides with the approach stop member 14 and stops (see FIG. 11). At this time, since the distance between the outer periphery of the guide roller 45 and the entry stop member 14 is arranged to be slightly longer than the length of the transported sheet in the transport direction, it is also provided on the outer peripheral surface of the guide roller 45. Since the distance between the outer periphery of the brush member 47 and the entrance stop member 14 is arranged to be slightly shorter than the conveying direction of the conveyed sheet, the rear end 34 of the sheet is With the rotation of the brush member 47 provided on the surface, it moves from a thick solid line to a thick two-dot chain line,
Pressed to. Next, the sheets are clamped by the conveyor belts 8 and 9 as shown in FIG. 12, and the rear end 34 and the rear end 34a of the sheets are in the state shown in FIG. That is, the rear end 34 of the paper sheet is subjected to the forced deformation force and is pressed against the transport belt 9. The amount of deformation at this time is regulated by the carry-out guide frame 13, and the rear end 34 of the paper sheet is forcibly deformed, so that the rigidity of the paper sheet becomes apparently large, and the paper sheet becomes smooth. Can enter the conveyance path clamped by the conveyance belts 8 and 9. Thereafter, the sheet is conveyed along a merging guide 16 shown in FIG. 9 and reaches the clamping portion of the conveying belts 9 and 5, and is conveyed downward. Therefore, the paper sheets nipped by the conveyor belts 5 and 9 and conveyed downward are all conveyed as front-facing paper sheets in the same direction as the front-facing paper sheets. Further, the transfer time from the gate 11 to the holding portions of the conveyor belts 5 and 9 through the holding portions of the transfer belts 5 and 7 and the gate 11 through the holding portions of the transfer gelts 6 and 8 from the gate 11,
The transport path length and transport speed of each transport path are set so that the transport time including the reversal time from the reversing operation of the transported paper sheets to the holding portions of the transport belts 5 and 9 becomes substantially equal. For this reason, only the paper sheets judged to be face-down by the discriminating section 1 are sorted by the gate 11, the sheet is turned upside down in the above-mentioned conveyance path, and is conveyed to the post-processing section by the conveyance belts 5 and 9. There is no inconsistency in processing without causing a variation in the interval with the paper sheet. In the embodiment shown in FIG. 9, when a backward skewed sheet is conveyed, the skew is corrected by the same operation as the embodiment shown in FIG. Further, at the time of the reversing operation shown in FIGS. 10 to 12, two or more sheets to be reversed, such as the reversing sheet attempting to enter the reversing sheet after the reversing sheet. When the vehicle continuously enters in a state of approaching, similar to the embodiment shown in FIG. 1, the action of the guide roller 45 does not cause any trouble such as a jam.
An inversion operation can be performed. Further, even when a non-reversed sheet having an abnormally short length in the conveying direction, for example, a folded sheet enters the conveying path, the sheet is smoothly conveyed similarly to the embodiment shown in FIG. be able to. As described above, in the embodiment shown in FIG. 9, the flexible member as the paper sheet pressing member provided on the outer peripheral surface of the guide roller 45 is a brush member 47 made of a thin wire such as nylon. Since the sheet is made of an elastic material, the sheet is hard to be damaged, and the frictional force between the sheet and the rear end 34 of the sheet is increased, so that the rear end 34 of the sheet is smoothly transported. It can be moved from the belt 6 to the conveyor belt 9 side. Further, the shape and material of the flexible member provided on the outer peripheral surface of the guide roller 45 are not limited to the shapes and materials shown above, and for example, FIGS. 13 (a), (b) and (c). Various shapes are conceivable as shown in FIG. FIG. 13A shows that a brush member 47 as a flexible member is disposed on the outer peripheral surface of the guide roller 45 so as to be inclined with respect to the radial direction. The amount is reduced. FIG. 13 (b)
Is an example in which an elastic body 48 such as a rubber material is disposed as a flexible member, and FIG.
The flexible member is provided directly on the shaft. The operation and function of these guide rollers are completely the same. In the embodiment shown in FIGS. 9 to 13, the sheet pressing member provided on the outer peripheral surface of the guide roller 15 is constituted by a flexible member. Is set to be slightly shorter than the length of the paper sheet in the transport direction, so that even if the paper sheet is transported in a state in which the transport direction length of the paper sheet is short, the flexible member can , A reversing operation can be performed smoothly.
