For example, the flow shown in FIG. 9 is executed at the time of the collating operation when the sorting mode is selected as the discharge mode, and the flow shown in FIG. 12 is executed at the time of the collating operation when the stacking mode is selected as the discharge mode. Main motor 30, wing motor 51 and electromagnetic clutch 82a
To 82j. The details of this control will be described later in the section of the operation.

Next, the operation of the above configuration will be described with reference to FIGS. First, the collating operation in the case where the sorting / stacking mode is selected as the paper discharge mode will be described. FIG. 9 is a flowchart of the sorting stacking mode as described above, FIG. 10 is a timing chart of each part thereof, and FIGS. 11 (A) and 11 (B).
7A and 7B are schematic front views each showing an operation of the paper discharge wing in the sorting 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. Further, the width of the pair of side fences 43 and 44 is adjusted to be larger than the width of the sheet 1 (about +30 mm). 9 to 11, when the start switch is turned on (step S1), the main motor 30 is driven (step S1).
2) Each of the electromagnetic clutches 8 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.
Under the control of 2a to 82j, the paper 1 of each type (content) is sequentially conveyed to the collating and conveying unit B one by one by rotating sequentially from the top (step S3). Each conveyed sheet 1 is conveyed downward while being collated at the location of the transport roller 15 of the collation transport section B, and the final collation process is performed at the location of the transport roller 15 at the lowest position, and the desired collet is processed. Compound 2. The collated product 2 enters the discharge section C and the conveyance path change guide plate 21
With the rotation of the pair of discharge rollers 26 and 27, the sheet is discharged to the stacker section D by the rotation of the pair of discharge rollers 26 and 27.

Then, as shown in FIG. 10, when the collation 2 passes through the discharge section C, the timing at which the detection output of the discharge detection sensor S3 changes from L level to H level is detected (step S4). After a lapse of a predetermined time (t1), driving of the wing motor 51 is started (step S1).
5) When the cylindrical cam 57 has rotated 180 degrees from the reference rotation position (step S6), the driving of the wing motor 51 is stopped (step S7).

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
The right end is inclined downward and falls first while shifting to the right. 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.

Next, in the same manner as described above, each sheet 1 from each of the sheet feeding tables 3a to 3j of the sheet feeding section A is conveyed, and the collation conveying section B
Is discharged through the discharge section C (steps S1 to S3). Then, when the timing at which the detection output of the paper ejection detection sensor S3 changes from the L level to the H level is detected (step S4), the drive of the wing motor 51 is started after a lapse of a predetermined time (t1) (step S5).
When the cylindrical cam 57 rotates 180 degrees (step S6)
To stop the driving of the wing motor 51. Thus, the cylindrical cam 57 returns to the original reference rotation position.

Here, when the cylindrical cam 57 rotates from the 180-degree rotation position to the reference rotation position, FIGS.
As shown in (B), the discharge wing 48 on the right side is displaced from the standby position to the interference position for a predetermined time in substantially the same manner as described above.
The right end of the bundle 2 discharged from the discharge unit C contacts the right discharge wing 48, and the left end of the bundle 2 contacts the left side fence 43 and is placed on the discharge table 42. .

That is, the wing motor 51 is driven each time the detection output of the sheet discharge detection sensor S3 changes from the L level to the H level to alternately cause the pair of left and right discharge wings 47 and 48 to interfere with each other. , The sheets are stacked with a shift amount d1 left and right for each of the bundles 2.

The control unit 68 counts the number of collated sets by such collating operation, checks whether the set number of collated sets has been reached (step S8), and sets the set number of collated sets. This series of operations is continuously executed until the number of times reaches. When the set number reaches the set number, the drive of the main motor 30 is stopped (step S8), and the collating operation is completed.

Next, the collating operation when the stacking mode is selected as the paper discharging mode will be described. 12 is a flowchart of the stacking mode as described above, FIG. 13 is a timing chart of each part thereof, and FIGS. 14A and 14B are schematic front views showing the operation of the paper discharge wing in the stacking mode.

For example, nine sheets 1 of different types (contents)
When it is desired to collate, a large number of sheets 1 classified by type (content) from the uppermost paper feed tray 3a to the lowermost one paper feed tray 3i are attached in collation order, and Paper feed tray 3 at the bottom
The interleaving paper 84 (shown in FIG. 14), which is the identification paper for sorting, is loaded on each of the paper feed tables 3a to 3j. The interleaving paper 84 is preferably a visually noticeable paper such as colored paper. Further, the width of the pair of side fences 43 and 44 is adjusted to be slightly larger than the width of the sheet 1. As shown in FIGS. 12 to 14, when a start switch (not shown) is turned on (step S10), the main motor 30 is driven (step S11), and the main motor 30 is sequentially moved from the paper feed roller 9 of the uppermost paper feed table 3a to the uppermost one. Paper tray 3 above the lower one
i to each of the electromagnetic clutches 82a to 82i
, The paper 1 of each type (content) is sequentially conveyed to the collating and conveying unit B one by one by rotating from the top (step S12). Each conveyed sheet 1 is conveyed downward while being collated at the location of the transport roller 15 of the collation transport section B, and the final collation process is performed at the location of the transport roller 15 at the lowest position, and the desired collet is processed. Compound 2. The collated product 2 enters the discharge section C, advances by the conveyance path changing guide plate 21 on the stacker section D side as a conveyance path, and is discharged to the stacker section D by rotation of the pair of discharge rollers 26 and 27.

Here, as shown in FIG. 13, when the bundle 2 passes through the discharge section C, the sheet discharge detection sensor S3 detects this. However, unlike the above-described sorting mode, the wing motor 51 is driven. Not done. Therefore, the collated product 2 discharged from the discharge unit C falls without being interfered by the pair of discharge wings 47 and 48 and is stacked on the discharge table 42. Then, such a collating operation is executed for the set number of interleaved sets (the number of sets interposing the interleaf 84) (step S).
13) A predetermined number of sets 2 are stacked.
In the first embodiment, as shown in FIG. 14B, a slip sheet 84 is interposed for each set.

When the collating operation is executed for the set number of interleaved sets (the number of sets interposing the interleaf 84) (step S13), the sheet feeding roller 9 of the lowermost sheet feeding table 3j is driven by each electromagnetic force. Rotated by the control of the clutch 82j, only the slip sheet 84 is transported to the collating transport section B (step S14). The transported interleaving paper 83 passes through the collating transport section B and is discharged to the discharging section C.
And is discharged to the stacker section D by the rotation of the pair of discharge rollers 26 and 27.

Then, as shown in FIG. 13, when the slip sheet 84 passes through the discharge section C, the timing at which the detection output of the discharge detection sensor S3 changes from L level to H level is detected (step S15). After the elapse of the predetermined time (t1), the driving of the wing motor 51 is started (step S1).
16) When the cylindrical cam 57 has rotated 360 degrees from the reference rotation position (step S17), the driving of the wing motor 51 is stopped (step S18).

Here, when the cylindrical cam 57 rotates 180 degrees from the reference rotation position, as shown in FIGS. 13 and 14A, the left discharge wing 47 is moved from the standby position substantially in the same manner as described above. The sheet is shifted to the interference position for a predetermined time, and the left end of the slip sheet 84 discharged from the discharge section C is located on the left discharge wing 4.
7 and the right end of the slip sheet 84 is on the right side fence 4
4 and is placed on the paper discharge table 42. Therefore, the slip sheet 8
4 is loaded in a state where it is offset with respect to the collation 2. When the cylindrical cam 57 rotates from the 180-degree rotation position to the reference rotation position, the right discharge wing 48 is shifted from the standby position to the interference position for a predetermined time, but the right discharge wing 48 interferes. Since the slip sheet 84 has already fallen onto the sheet discharge tray 42 at the timing of the position, the right sheet discharge wing 48 does not interfere with the slip sheet 84 at all.

Further, the control section 68 counts the number of collated sets in the collating operation step in which the interleaving operation step is interposed, and checks whether or not the set number has been reached (step S19). This series of operations is continuously performed until the set number reaches the set number. When the set number reaches the set number, the driving of the main motor 30 is stopped (step S20), and the collating operation is completed.

In other words, in the stacking mode in the present invention, the sheet 1 to be collated is fed from the paper feeding section A, and the collated material 2 discharged from the discharge section C is stacked on the paper discharge table 42. In the joining operation step, the interleaving paper 84 which is the sorting identification paper is conveyed from the paper feeding unit A, and the interleaving paper 84 discharged from the discharging unit C is separated by the discharge wing 47 of the sorting stacking unit 46 into the collated product 2. Since the operation process is divided into an identification paper operation process to be placed with offset and the identification paper operation process is interposed every predetermined number of collation operation processes, as shown in FIG. 2 are stacked without being offset, and a slip sheet 84 is interposed at a boundary of each of the predetermined number of sets 2 in a state of being offset with respect to the sets 2. Therefore, the position of the slip sheet 84 can be determined at a glance, and the sorting is easy.

In the first embodiment, the sorting / stacking means 46 has a pair of paper discharge wings 47 and 48, and the pair of paper discharge wings 47 and 48 are discharged from the discharge section C. Since the sheet discharge direction is offset in a direction substantially orthogonal to the sheet discharge direction by interfering with the slip sheet 84, the moving load is small, and the amount of sheets 1 stacked on the sheet discharge table 42 and a pair of sheet discharge wings The wing motor 51 is simply independent of the pair of paper ejection wings 4
What is necessary is just to be able to obtain the driving force for moving 7,48. Therefore, the load on the wing motor 51 can be reduced.

In the first embodiment, the wing motor 51 is driven so that the cylindrical cam 57 rotates 360 degrees from the reference rotation position when the slip sheet 84 is discharged in the stacking mode. It may be configured as follows. However, in this case, the offset direction of the interleaving paper 84 is alternately left and right with respect to the collated product 2.

In the first embodiment, utilizing the fact that the interleaving paper 84 can be offset to the left and right with respect to the collated product 2, a small number of sets and a rough Can be divided into numbers. That is, a small number of sets (for example, 1
When it is desired to divide the slip sheet 84 into a set of rough sets (for example, every 10 sets) and a rough set unit (for example, every 10 sets), for example, the slip sheet 84, which is offset to the right for each small number of sets, The convenience of sorting can be further improved by interposing a slip sheet 84 offset to the left.

In the first embodiment, the sorting and stacking means 46 is used.
Has a pair of left and right paper discharge wings 47 and 48, but may have only one of the right and left. However, providing a pair of left and right sides increases the offset amount of the collated product 2 in the sorting stacking mode, and as described above, the slip sheet 8 in the bar stacking mode.
4 offset variations increase.

Further, in the first embodiment, the case where the interleaving paper 84 different from the paper 1 to be collated is used as the sorting identification paper is shown. It is also possible to use a sheet 1 serving as a cover. In this case, the sheet 1 serving as the front cover or the back cover of the collection 2 is stacked offset from the other collection 2. That is, conventionally, the collation 2 and the interleaving paper 84 were stacked without offset, so that such use is impossible.
In the present invention, since the collation 2 and the sorting identification paper (interleaf 84) are offset and stacked, the paper 1 serving as the front or back cover of the collation 2 can be used as the classification identification paper. In this way, there is no need to separately prepare a slip sheet 84. Further, in the stacking mode in which the identification paper for sorting is interposed, all the paper feed tables 3a to 3j of the paper feed unit A can be used for the paper 1 to be collated, so that the number of collatable sheets is increased by one. .

15 to 17 show a second embodiment of the present invention. FIG. 15 is a perspective view of a stacker portion, FIG. 16 is a partial front view thereof, 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 sorting and stacking means 46 of the stacker portion D is different, and the other configuration is the same. The explanation is omitted, and different sorting means 4
Only the configuration of No. 6 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, as shown in FIGS. 15 and 16, the section stacking means 46 of the second embodiment has a pair of side fences 43, 44 with a pair of vertical links 63, 63 and a pair of auxiliary vertical links. Links 90, 90 are provided rotatably. One end of an intermediate horizontal arm 91 and an auxiliary arm member 92 extending in the horizontal direction is fixed to each of the vertical links 63 and the auxiliary vertical links 90, and an engagement pin 93 at a central portion of each of the intermediate horizontal arms 91 is connected to the auxiliary arm member. It is engaged in a long hole 94 in the middle part of the 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 left and right discharge wings 47 and 48 is at the standby position. It is located at a retreat position (virtual line position in FIGS. 17A and 17B) 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 discharge wings 47 and 48 and further inwardly from the ends of the pair of paper discharge wings 47 and 48 by an R dimension (solid line positions in FIGS. 17A and 17B). 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. 17A and 17B
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. Also has the same operation and effect as in the first embodiment in the divided stacking mode and the bar stacking mode.

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.

In each of the above embodiments, the collating device having the pair of paper ejection wings 47 and 48 has been described. However, the present invention can be applied to a collating device having no paper ejection wing. In other words, in the stacking mode, the sorting identification paper is collected using the mechanism for sorting and stacking.
In this case, the sheet may be stacked on the sheet discharge table 42 in an offset state. For example, the present invention can also be applied to a collating device in which a paper discharge table moves as in a conventional example. Although only the bar stacking mode with the interleaving paper 84 interposed has been described, it goes without saying that the bar stacking mode in which the stacking is performed without the interposition of the interleaving paper 84 is also possible. Further, the drive mechanism 50 for the pair of paper ejection wings 47 and 48 is configured using the worm gear 52 and the worm wheel 53, but may be configured using only the flat gear.
