This will be described with reference to FIG. FIG. 10 is a timing chart in the sorting and stacking mode, and FIGS. 11A and 11B are schematic diagrams showing the operation of the discharge wing in the sorting and stacking mode.

For example, when it is desired to collate ten sheets 1 of different types (contents), a large number of sheets classified by type (contents) from the uppermost sheet feeder 3a to the lowermost sheet feeder 3j. 1 are stacked on each of the paper feed tables 3a to 3j in a collated order. When the start switch is turned on, the main motor 3
0 is driven, and from the paper feed roller 9 of the uppermost paper feed tray 3a to the paper feed roller 9 of the lowermost paper feed tray 3j are sequentially rotated from the top by the control of each electromagnetic clutch, and each type (content) is rotated.
Sheets 1 are sequentially conveyed one by one to the collating and conveying section B. Each of the transported sheets 1 is transported by a transport roller 15 of a collating transport section B.
Are conveyed downward while being collated at the position, and the final collation processing is performed at the position of the transport roller 15 at the lowermost position to obtain a desired collated product 2. The collated product 2 enters the discharge section C, advances by the conveyance path changing guide plate 21 on the stacker side as the conveyance path, and is discharged to the stacker section D by the rotation of the pair of discharge rollers 26 and 27. Then, by executing this series of operations continuously, one unit of the collation 2 is sequentially discharged.

Here, in the case of the bar stacking mode, the collated product 2 is placed on the paper discharge tray 42 by trial collation, or the sheet 1 is manually placed at a predetermined position on the paper discharge tray 42. The pair of side fences 43 and 44 are slightly larger than the width of the collation 2 (paper 1) with respect to the collation 2 (or paper 1).
Adjust the width of. Then, since the wing motor 51 is not driven and the pair of paper discharge wings 47 and 48 both maintain the standby position, they are stacked on the paper discharge table 42 without being offset left and right by one unit of the collation 2. .

Further, in the case of the sorting stacking mode, the collated material 2 is placed on the paper discharge tray 42 by trial collation, or the paper 1 is placed at a predetermined position on the paper discharge tray 42 by hand. And this collation 2
A pair of side fences 4 larger (about +30 mm) than the width of the collated product 2 (paper 1) based on (or paper 1)
Adjust the width of 3,44. More specifically, as shown in FIG. 12, the position of the movable side fence 43 is adjusted such that the sectional stacking position mark portion 70 of the movable side fence 43 matches the width direction side end surface 2a of the collated product 2.

As shown in FIG. 9, when the timing at which the detection output of the paper discharge detection sensor S3 changes from the L level to the H level is detected (step S1), the wing motor 51 is driven after a predetermined time (t1) has elapsed. Driving is started (step S2), and the cylindrical cam 57 is moved from the reference rotation position by one.
When the wing motor 51 is rotated by 80 degrees (step S3), the driving of the wing motor 51 is stopped (step S4). Next, when the timing at which the detection output of the sheet discharge detection sensor changes from the L level to the H level is detected (step S1), the drive of the wing motor 51 is started after a lapse of a predetermined time (t1) (step S2), and the cylinder is driven. When the cam 57 rotates by 180 degrees (step S3), the driving of the wing motor 51 is stopped. Thus, the cylindrical cam 57 returns to the original reference rotation position.
Thereafter, the detection output of the sheet discharge detection sensor S3 changes from L level to H level.
The drive of the wing motor 51 is performed each time the timing at which the level is changed is detected.

Here, when the cylindrical cam 57 rotates 180 degrees from the reference rotation position, as shown in FIGS. 10 and 11A, the left discharge wing 47 is displaced from the standby position to the interference position. After the interference position is held for a predetermined time, the operation returns to the standby position again. Then, when the discharge wing 47 is located at the interference position, the left end of the collection 2 comes into contact with the left discharge wing 47 in accordance with the falling timing of the collection 2 discharged from the discharge section C. I do. Collage 2 due to this interference
Is shifted downward to the right with the right end inclined downward and falls first from the right end. As a result, the right end of the collation 2 falls while abutting on the right side fence 44, so that the collation 2 is restricted by the right side fence 44, that is, the right end of the collation 2 is on the right side fence. The sheet is placed on the sheet discharge table 42 in contact with the fence 44.

When the cylindrical cam 57 rotates from the 180-degree rotation position to the reference rotation position, when the cylindrical cam 57 rotates, as shown in FIGS.
As shown in (B), the right sheet discharging wing 48 is displaced from the standby position to the interference position, and returns to the standby position again after holding the interference position for a predetermined time. And this paper ejection wing 4
When the collet 8 is located at the interference position, the right end of the collation 2 comes into contact with the right discharge wing 48 in accordance with the falling timing of the collation 2 discharged from the discharge section C. Due to this interference, the collation 2 falls into a state in which the left end is inclined downward and falls from the left end first while shifting to the left. Therefore, since the left end of the collation 2 falls while abutting on the left side fence 43, the collation 2 is restricted by the left side fence 43, that is, the left end of the collation 2 is on the left side fence. The sheet is placed on the sheet discharge table 42 in contact with the fence 43.

Since the operation of the pair of left and right paper discharge wings 47 and 48 is performed in synchronization with the discharged bundle 2, each bundle 2 is offset right and left by the shift amount d 1. Loaded.

As described above, according to the present invention, as described above, the pair of side fences 43 and 44 in the divided stacking mode are used.
As shown in FIG. 12, the width adjustment of the movable side fence 43 is performed so that the sectional stacking position mark portion 70 of the movable side fence 43 matches the width direction side end surface 2a of the collated product 2 (paper 1). Since the position may be adjusted, the width between the pair of side fences 43 and 44 can be easily and accurately adjusted. Here, when creating an alignment mark portion for sorting and stacking on the paper discharge tray 42, the method is effective only for the fixed size (A4 size, B5 size, etc.) paper 1; This is effective regardless of the size of the irregularly shaped paper 1.

In the first embodiment, the sectioning position mark 70 is provided on the bottom surface 4 of the movable side fence 43.
3b is formed by coloring, so that the sorting stack position mark portion 7
0 can be easily created.

13 to 15 show a second embodiment of the present invention. FIG. 13 is a perspective view of a stacker portion, FIG. 14 is a partial front view of the stacker portion, and FIGS. FIG. 9 is a schematic diagram illustrating the operation of the paper ejection wing in the mode. When comparing the second embodiment with the first embodiment, only the configuration of the section stacking means 46 of the stacker portion D is different, and the other configuration is the same. For example, the same applies to the bottom surface 43b of the movable side fence 43. Is provided with a section stacking position mark section 70. In addition, the same components will not be described in order to avoid redundant description, and only different configurations of the sorting and stacking means 46 will be described. In the drawings, the same components as those in the first embodiment are denoted by the same reference numerals and are clarified.

That is, in FIG. 13 and FIG.
In the section stacking means 46 of the embodiment, a pair of auxiliary vertical links 90, 90 in addition to the pair of vertical links 63, 63 are rotatably provided on the pair of side fences 43, 44. Each vertical link 63 and each auxiliary vertical link 90 have an intermediate horizontal arm 91 and an auxiliary arm member 9 extending horizontally.
One end of each arm 2 is fixed, and an engagement pin 93 at the center of each intermediate horizontal arm 91 is engaged with a long hole 94 at the middle of the auxiliary arm member 92.

That is, the auxiliary arm member 92 moves in the horizontal direction in conjunction with the rotation of the wing pressing arm 65, and is discharged from the discharge portion C when the pair of discharge wings 47 and 48 are at the standby position. It is located at an exit position (a virtual line position in FIGS. 15A and 15B) that does not interfere with the collation object 2,
When the pair of paper ejection wings 47 and 48 are at the interference position,
A protruding position below the pair of paper ejection wings 47 and 48 and further inwardly from the tip of the pair of paper ejection wings 47 and 48 by an R dimension (solid line positions in FIGS. 15A and 15B). Located in. The other components of the sorting and stacking means 46 are the same as those in the first embodiment, and thus the description thereof is omitted.

In the above configuration, FIGS. 15A and 15B
As shown in (2), by controlling the left discharge wing 47 and the right discharge wing 48 to move to the interference position alternately in synchronization with the collated product 2 to be discharged. The second embodiment has the same operation and effect as the first embodiment. That is, the width adjustment of the pair of side fences 43 and 44 in the divided stacking mode is performed such that the divided stacking position mark portion 70 of the movable side fence 43 is aligned with the width direction side end face 2 a of the collation 2. Fence 43
It is only necessary to adjust the position of the pair of side fences 4
The width adjustment between 3 and 44 can be performed easily and accurately.

In the second embodiment, FIG.
As shown in (A) and (B), at the interference position, the auxiliary arm member 92 is located further inside than the distal ends of the pair of discharge wings 47 and 48, and further assists inside the pair of discharge wings 47 and 48. Since the arm member 92 interferes with the collection 2 and changes the discharge direction of the collection 2, the pair of discharge wings 4
The offset amount d2 of the section stack can be increased without increasing the length of 7,48. That is, in order to increase the offset amount of the sorting stack, a pair of the discharge wings 47,
It is conceivable that the length of the pair of discharge wings 47 and 48 is increased. However, if the length of the pair of discharge wings 47 and 48 is increased, the locus of movement of the lower ends of the pair of discharge wings 47 and 48 is lowered accordingly, and the discharge This interferes with the sheets 1 stacked on the table 42 and limits the stacking amount. Therefore, a pair of paper ejection wings 4
The length of 7, 48 cannot be increased, and the offset amount is limited. However, according to the second embodiment, this can be solved.

FIGS. 16A, 16B, and 16C are perspective views of side fences showing first to third modifications of the sectional stacking position mark section 70, respectively. In the first modified example of FIG. 16A, the sectional stacking position mark portion 70 is formed by a central colored line portion 71 and left and right colored line portions 72. That is, the offset amount can be set to a standard offset amount by adjusting to the center colored line portion 71, and slightly larger or slightly smaller than the standard by adjusting to the left and right colored line portions 72. As the offset amount of the sorting stack may have a slightly different size depending on the user who uses it or the purpose of use of the collation 2 or the like, the use value can be increased by doing so. Further, it may be constituted by a scale indicating the size from the inner wall of the side fence 43. In this case, the offset amount can be more finely adjusted.

In the second modification shown in FIG. 16B, the sectional stacking position mark portion 70 is formed by providing a slit-shaped notch 73 on the bottom surface 43b of the side fence 43. In the third modification of FIG. 16C, the sectional stacking position mark section 70 is formed by providing a projection 74 on the bottom surface 43 b of the side fence 43. Notch 7
Since the 3 or the protrusion 74 can be identified not only visually but also by tactile sensation, the visually impaired person can easily and accurately adjust the width between the pair of side fences 43 and 44.
Note that the sectioning stack position mark section 70 may be configured with a part other than the notch 73 or the projection 74 as long as it can be identified not only visually but also by tactile sensation.

The notch 73 or the projecting portion 74 may be used as the first modified example.
A scale indicating the size from the inner wall of the side fence 43 may be formed by the protrusion 3 or the protrusion 74. Further, one of the pair of side fences 43 and 44 is movable and the other is fixed, but both may be configured to be movable. In this case, the sectional stacking position mark portions 70 are provided on the bottom surfaces of both side fences 43 and 44. However, the total size of both of the side fences 43 and 44 from the inner wall is set to a value substantially matching the desired offset amount. Further, the drive mechanism 50 for the pair of paper ejection wings 47 and 48 includes a worm gear 52.
And the worm wheel 53, but may be configured using only a spur gear. Furthermore, a scale may be provided on the bottom surface of the fixed side fence of the pair of side fences 43 and 44 for adjustment. In this case, the movable side fence is moved after the edge of the paper is first adjusted to the scale.
