Each of the pressing rollers 16 arranged in the vertical direction is urged toward the conveying roller 15 by a spring (not shown), and a conveying belt 17 is hung between the pressing rollers 16, 16,. Each of the rollers 16 is in pressure contact with the transport roller 15 via the transport belt 17.
[0024]
In addition, vertical guide plates 18 and 19 are provided on both sides of the conveyance belt 17 portion in pressure contact with each conveyance roller 15 and each pressing roller 16, and a vertical conveyance path is provided between the vertical guide plates 18 and 19 on both sides. 20 is configured. One vertical guide plate 18 is composed of a single plate, while the other vertical guide plate 19 is composed of a plurality of plates integrally with the upper and lower guide plates 10 and 11 of the paper feeding section A.
[0025]
When each conveying roller 15 rotates, the conveying belt 17 that is rotatable by the pressing roller 16 is moved by the frictional force of the conveying roller 15, and the sheet 1 conveyed from the paper feeding unit A is rotated by the rotating conveying roller. 15 is sandwiched between the moving belt 15 and the moving conveying belt 17 and is conveyed downward along the vertical conveying path 20. Here, when the sheet 1 conveyed from above passes the lower conveyance roller 15, the sheet 1 on the lower paper feed table side is conveyed to the collating conveyance unit B, so that the lower sheet 1 is moved upward. The paper 1 is transported downward in a superimposed manner. The conveyance of the sheet 1 and the overlapping operation of the sheet 1 are repeated to produce a desired collated product, and this collated product is further conveyed to the lower discharge unit C.
[0026]
As shown in FIG. 2, the discharge section C has a conveyance path change guide plate 21. The conveyance path change guide plate 21 is a stacker position indicated by a solid line in FIG. 2, and an imaginary line in FIG. It is provided so as to be rotatable between the position for the post-processing machine indicated by. In this embodiment, the conveyance path changing guide plate 21 is urged by a spring (not shown) to the stacker position side and is driven by an electromagnetic solenoid 81.
[0027]
That is, when the electromagnetic solenoid 81 is in the off state, it is positioned at the stacker position, and when the electromagnetic solenoid 81 is in the on state, it is positioned at the post-processing machine position. At the stacker position, the upper end of the transport path changing guide plate 21 is positioned along one vertical guide plate 18 of the collating transport section B, and the collated product 2 transported from the collating transport section B is the stacker section D. Led to the side. At the position for the post-processing machine, the upper end of the transport path changing guide plate 21 is positioned along the other vertical guide plate 19 of the collating transport section B, and the collated material transported from the collating transport section B is the stacker section D. It is led to the opposite side.
[0028]
Further, a stacker part side guide plate 22 and a post-processing machine side guide plate 23 are provided below the conveyance path changing guide plate 21, and the collated material 2 is selectively passed through the guide plates 22 and 23. Be transported.
[0029]
The discharge sensor S3 includes a light emitting unit 24 and a light receiving unit 25 that are disposed around the stacker side guide plate 22 in the vicinity of the discharge rollers 26 and 27 and upstream of the discharge path, and the amount of light received by the light receiving unit 25. The discharge timing of the collated product 2 is detected based on the level of. That is, when the passage of the collated object 2 starts, the light from the light emitting unit 24 is blocked and the output of the light receiving unit 25 becomes H level, and the light from the light emitting unit 24 is not blocked again at the end of the passage. Since the output returns to the L level, it is possible to detect the discharge timing of the collage 2. Further, the discharge sensor S3 detects a paper jam in the discharge unit C when, for example, the L level of the sensor output continues for a predetermined time or more.
[0030]
A pair of discharge rollers 26 and 27 arranged in the vertical direction is provided at a position downstream of the stacker portion D side guide plate 22 and facing the stacker portion D. The pair of discharge rollers 26 and 27 are arranged in a substantially pressure contact state, and the upper end portion of the lower discharge roller 27 slightly protrudes upward from the stacker portion side guide plate 22.
[0031]
Then, when the upper discharge roller 26 rotates, the lower discharge roller 27 is rotated following this, and the collated material conveyed from the collation conveying section B is between the pair of discharge rollers 26, 27. And discharged to the stacker portion D by the rotation of the pair of discharge rollers 26 and 27.
[0032]
The stacker part D is located on the outer side of the paper discharge table 42 provided at the dropping position of the collated material discharged from the discharge unit C and the collated material discharged on the paper discharge table 42. It has a pair of side fences 43 and 44 which restrict | limit the discharge direction of a compound to the direction orthogonal to this. The pair of side fences 43 and 44 are movably provided, and the distance between the side fences 43 and 44 can be changed according to the width of the sheet 2 to collate. Further, a front fence 45 that restricts the front of the collated object 2 in the discharge direction is disposed on the discharge table 42.
[0033]
A pair of paper discharge wings 47 and 48 are provided in the cutout holes 43a and 44a of the side fences 43 and 44, respectively. The paper discharge wings 47 and 48 are rotated so as to be displaced between a standby position that does not interfere with the collated material discharged from the discharge portion C and an interference position that interferes with the collated material 2 discharged from the discharge portion C. It is moved and regulates the drop position of the collated material discharged from the discharge part C. In the collating apparatus according to the present embodiment, the collating object stacking form on the paper discharge table 42 can be changed by restricting the drop position of the collated object with the paper discharge wings 47 and 48.
[0034]
For example, when collated items are stacked without driving the paper discharge wings 47 and 48, so-called bar stacking as shown in FIG. 4 is performed, and paper discharge is performed as shown in FIGS. 5 (a) and 5 (b). By alternately displacing the wings 47 and 48 between the standby position (illustrated by the dotted line in the figure) and the interference position (illustrated by the solid line in the figure), the fall position of the collated object is shifted by d and discharged to the right or the left. In such a case, the so-called segmented stacking as shown in FIG.
[0035]
Further, a full sensor 50 is provided in the stacker part D. The full sensor 50 detects the amount of collated material on the paper discharge tray 42 and is disposed at a predetermined height from the upper surface of the paper discharge tray 42. The full sensor 50 is composed of a light emitting unit and a light receiving unit that are arranged to face each other with a collate discharge path, and detects the full size of the collated product 2 based on the level of light received by the light receiving unit. Is. That is, when the collated object 2 is loaded and reaches a predetermined height, the light from the light emitting unit is blocked and the amount of light received by the light receiving unit is reduced, and the fullness of the collated object can be detected.
[0036]
Further, the full load sensor 50 according to the present embodiment performs detection independently of a collating sequence described later, and is in an OFF state while the light receiving unit is receiving light as shown in FIG. Thus, it is determined to be full when it is turned on by light shielding and the ON state is continuously 1000 ms or longer. Therefore, even if the full load sensor 50 is in the ON state as shown in the figure, if the state is continuously 1000 ms or less (300 ms, 250 ms in the example in the figure), it is not determined that the full load sensor 50 is full.
[0037]
(Collation operation)
Next, the collating operation of the collating apparatus having the above configuration will be described. First, the collating operation when the sorting and stacking mode is selected as the paper discharge mode will be described.
[0038]
When the collating operation is started, the main motor is driven, and each type (content) of paper 1 from the uppermost paper feed tray 3a to the lowermost paper feed tray 3j in order one by one. B is fed. Each of the fed sheets 1 is collated while being collated by the collation conveyance unit B, and is collated while being collated. The collated material 2 enters the discharge portion C and is discharged to the stacker portion D by the rotation of the pair of discharge rollers 26 and 27.
[0039]
When the collated product 2 passes through the discharge section C and detects the timing at which the detection output of the discharge sensor S3 changes from the L level to the H level, the stacker operation is started after the predetermined time has elapsed, and the discharge wing 47 is driven. And restrict the drop position of the collage.
[0040]
Subsequently, when the next cycle is started, each sheet 1 from each sheet feed table 3a to 3j of the sheet feeding section A is fed in the same manner as described above, and the collated product 2 is ejected from the collating transport section B. Discharged through C. Then, as shown in FIG. 7, when the detection output of the discharge sensor S3 changes from the L level to the H level, the stacker operation is started after the predetermined time (t1) has elapsed, and the discharge wing 48 is driven. Then, the drop position of the collated object is regulated so as to deviate from the previous cycle.
[0041]
That is, each time the timing when the detection output of the discharge sensor S3 changes from the L level to the H level is detected, the pair of left and right discharge wings 47 and 48 are alternately positioned at the interference position, so that Each is loaded with an offset of the shift amount d1 to the left and right.
[0042]
Next, the collating operation when the bar stacking mode is selected as the paper discharge mode will be described.
[0043]
When the collating operation is started, the main motor is driven, and one sheet 1 of each type (content) from the uppermost sheet feed tray 3a to the uppermost sheet feed tray 3j in order. The sheets are sequentially fed to the collating conveyance unit B one by one.
[0044]
Each of the fed sheets 1 is collated at the position of the conveyance roller 15 of the collation conveyance section B while being conveyed downward and subjected to a collation process to obtain a desired collation 2. The collated material 2 enters the discharge portion C and is discharged to the stacker portion D by the rotation of the pair of discharge rollers 26 and 27.
[0045]
Here, when the collated product 2 passes through the discharge portion C, the discharge sensor S3 detects this, but unlike the above-described division stacking mode, the discharge wings 47 and 48 are not driven. Accordingly, the collated material 2 discharged from the discharge portion C falls without being interfered with the pair of paper discharge wings 47 and 48 and is loaded on the paper discharge tray 42.
[0046]
(Collation sequence)
Next, the collating sequence of each part in the collating operation as described above will be described. In the present embodiment, when the above-described series of one-collation operations is defined as one cycle and a plurality of cycles are performed, detection of collation discharge by the discharge sensor S3 is triggered by the start of the next cycle. FIG. 7 is a timing chart showing an operation sequence of each part in one cycle.
[0047]
First, when a collation cycle is started ((1) in the figure), the electromagnetic clutch 82a is driven in the uppermost sheet feed table 3a to start sheet feeding. At this time, detection by the double feed detection sensor S2 (double feed detection sensor S2a) provided in the paper feed tray 3a is started, and the idle feed in the paper feed tray 3a is monitored. That is, if the “paper present” state does not occur within a predetermined time after the collation cycle is started, it is determined that the idle feeding has occurred. The double feed detection sensor S2 also monitors the occurrence of a paper jam at the same time as detecting an empty feed according to the paper size (for example, B5 width, A4, A3, A3SR, etc.) (6 in the figure). That is, if the paper trailing edge position (“no paper”) detected by the trial collation is not detected within a predetermined time, it is determined that a paper jam has occurred. Further, the double feed detection sensor S2 also monitors the occurrence of double feed for a predetermined time after feeding is started ((5) in the figure).
[0048]
The same operation is performed in order from the upper sheet feed table 3a to the sheet feed table 3j. In other words, after a predetermined time ((2) in the figure) from the start of the collation cycle, the paper feed clutch of each paper feed stand is operated for a predetermined time ((3) in the figure), and each sheet is transported with a predetermined timing shift. Supply to the collating section. In this embodiment, the double feed detection sensor S2j of the lowermost sheet feed table 3j operates after a predetermined time ((4) in the figure) has elapsed since the operation of the lowermost sheet feed clutch was started. Let it begin.
[0049]
After the paper feed in all the paper feed trays is completed, the discharge detection by the discharge sensor S3 is started. Specifically, discharge detection is started after a lapse of a predetermined time (7 in the figure) after the collation cycle is started, and if there is no “paper present” within the predetermined time, a paper jam occurs at the discharge section C. Judge. The stacker operation is started after a predetermined time ((8) in the figure) has elapsed since the discharge sensor S3 determined that “paper is present”. Further, if “no paper” is not detected after a predetermined time ((9) in the figure) after the discharge sensor S3 determines that “paper is present”, it is determined that a paper jam has occurred.
[0050]
Then, when the discharge sensor S3 detects “no paper”, the other one of the combinations (4) to (6), (7) and (9) is that no error has occurred. Next cycle [Outside 1]

50 is always independently monitored from the collating sequence, and the fullness of the collated material is always monitored. When the ON state is continuously generated for 1000 ms or more, it is determined that the collated product is full.
[0051]
[Outside 2]

If the ON state does not elapse for 1000 ms or more at that point, it is not determined that the load is full, the next collation is started, and the full load is confirmed at the next next collation start timing. Even in such a case, since the position of the full load sensor 50 is designed with a margin enough to allow one collated object, trouble does not occur in the stacker portion D.
[0052]
(Effects of collation equipment)
According to such a collation apparatus according to the present embodiment, by detecting the discharge of the collation part as an opportunity to start the next cycle, for example, when the paper length is short, the next cycle is started early. The cycle length can be made variable according to the size of the paper, and the collating operation can be performed efficiently.
[0053]
Further, in the collation apparatus according to the present embodiment, the detection by the discharge sensor S3 and the detection by the full load sensor 50 are performed separately and further, the full detection by the full load sensor 50 is separated from the collation sequence. The time required for this determination can be omitted, and the collating operation can be speeded up.
[0054]
In the present embodiment, the discharge sensor S3 is provided in the vicinity of the discharge rollers 26 and 27 and upstream of the discharge path, so that the discharge is performed when the collated material is inserted between the discharge rollers 26 and 27. Completion can be determined and the next collation cycle can be quickly entered.
[0055]
【The invention's effect】
As described above, according to the collating apparatus of the present invention, jams such as a paper jam of the collated material in the discharge unit are detected effectively, and the cycle of the collating operation is adjusted according to the paper size. The efficiency of operation can be improved by omitting the time required for full load detection.
