Next, the operation of the above configuration will be described with reference to FIGS.
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 1 classified by type from the uppermost paper feed tray 3a to the lowermost paper feed tray 3j are collected. The sheets are stacked on each of the paper feed tables 3a to 3j in the combined order. When the start mode is selected, the main motor 30 is driven,
From the paper feed roller 9 of the uppermost paper feed table 3a to the paper feed roller 9 of the lowermost paper feed table 3j, the respective types (contents) rotate from top to bottom under the control of each electromagnetic clutch (not shown).
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 material 2 enters the discharge section C, travels on the stacker side as the conveyance path by the conveyance path changing guide plate 21, 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 stacking mode, the sheet 1
A pair of side fences 43 slightly larger than the width of
The width of 44 is adjusted. 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. .

In the case of the sorting stacking mode, the width of the pair of side fences 43 and 44 is adjusted to be larger (about +35 mm) than the width of the sheet 1. Then, as shown in FIG. 9, when the timing at which the detection output of the sheet discharge detection sensor S3 changes from the L level to the H level is detected (step S5).
1) After the predetermined time (t1) has elapsed, the wing motor 5
1 is started (step S2), and the cylindrical cam 57 is rotated 180 degrees from the reference rotation position (step S3).
To stop driving the wing motor 51 (step S
4). 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 wing motor 51 is driven each time the timing at which the detection output of the sheet discharge detection sensor S3 changes from the L level to the H level 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 holding the interference position 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. As a result of this interference, the collation 2 falls down from the right end while shifting rightward with the right end inclined downward. Therefore, since the right end of the collation 2 falls while abutting on the right side fence 44,
The collection 2 is restricted by the right side fence 44, that is, the right end of the collection 2 is the right side fence 4
4 and is placed on the paper discharge table 42.

When the cylindrical cam 57 rotates from the 180-degree rotation position to the reference rotation position, when the cylindrical cam 57 rotates from the 180-degree rotation position to the reference rotation position, as shown in FIGS.
As shown in (5), the right discharge wing 48 is displaced from the standby position to the interference position, and returns to the standby position after holding the interference position for a predetermined time. When the discharge wing 48 is located at the interference position, the right end of the collection 2 comes into contact with the right discharge wing 48 in accordance with the falling timing of the collection 2 discharged from the discharge section C. I do. 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.

The left and right discharge wings 4

Slot 9 in the middle of 92
4 is engaged.

That is, the auxiliary arm member 92 moves in the horizontal direction in conjunction with the rotation of the wing pressing arm 65, and when the discharge wings 47 and 48 are in the standby position, the collet discharged from the discharge portion C is collated. When the paper ejection wings 47 and 48 are located at the exit positions (the virtual line positions in FIGS. 14A and 14B) that do not interfere with the object 2 and the paper ejection wings 47 and 48 are at the interference position, the paper ejection wing 4
7 and 48, and the discharge wings 47 and 48
Are located at the protruding positions (solid line positions in FIGS. 14A and 14B) protruding further inward than the tip of R by an R dimension. 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.

Is located inside the discharge wings 47 and 48, and the auxiliary arm member 92 further interferes with the collection 2 to change the discharge direction of the collection 2 so that the length of the discharge wings 47 and 48 is increased. Without this, the offset amount d2 of the divided stack can be increased. In other words, in order to increase the offset amount of the sorting stack, it is conceivable to increase the length of the discharge wings 47, 48. However, if the length of the discharge wings 47, 48 is increased, the discharge wings 47, 48 may be increased. The movement trajectory of the lower end of the lower portion 48 is lowered by that amount, and interferes with the sheets 1 stacked on the sheet discharge tray 42, so that the stacking amount is limited. Therefore, the length of the paper discharge wings 47 and 48 cannot be increased, and the offset amount is limited. However, according to the second embodiment, this can be solved.

In each of the above embodiments, one of the pair of side fences 43 and 44 is configured to be movable and the other is fixed, but both may be configured to be movable. If the width of the paper 1 to be used is specified for some reason, both may be fixed.

In each of the above embodiments, the discharge wing 4
Although the drive mechanisms 50 of 7 and 48 are configured using the worm gear 52 and the worm wheel 53, they may be configured using only the spur gear.
