Predetermined processing is performed in the processing section 24. The processed cut sheet Q is discharged from the apparatus main body 1 toward the sheet sorting device 2.

The paper sorting device 2 is composed of an accumulation and transfer section 91 and a stacker section 92, and the processed paper sheets Q discharged from the device main body 1 are first received by the stacking section 95 of the accumulation and transfer section 91 and sorted. After being stacked in units, each stacked cut sheet Q' is continuously transferred to the stacker section 92 disposed on the downstream side. In the embodiment, the accumulation and transfer section 91 is provided with a conveyance roller that stacks the stacked cut sheets Q' on a plurality of rotating rollers 94 . Incidentally, instead of the plurality of rollers 94, the accumulation and transfer section 91 may be configured to include a belt conveyor 88 that stacks the stacked sheets Q' on a belt that runs around the belt.

The stacker section 92 continuously stacks the stacked sheets Q' transferred from the accumulation and transfer section 91 at different positions on the placement surface 83. Then, the control unit 45 controls the previously transferred stacked paper sheets Q' of the stacked paper sheets Q' transferred to the stacker section 92 by the accumulation and transfer section 91, and the subsequent stacked paper sheets Q'. control so that they form a predetermined gap. Incidentally, the stacker section is provided with a belt conveyor 86 that stacks stacked sheets Q' on a belt that runs around the belt.

(thickness added) to the downstream side, and the rotational drive is stopped. At this time, the discharge of the cut sheet Q from the conveyance roller 17 of the apparatus main body 1 is stopped.

(3) Next, as shown in FIG. 7(c), after the abutting guide 93 is again advanced downward with respect to the conveyance path, the cut sheet is removed from the conveyance roller 17 of the apparatus main body 1. The discharge of Q is resumed.

(4) Next, after the number of sheets Q loaded on the loading section 95 reaches the number of sheets to be sorted (sorting unit),
As shown in FIG. 7(d), after retracting the abutment guide 93 upward, the roller driving section 40 rotates the plurality of rollers 94 to rotate the stacked cut sheets Q'1 after the stacking. , Q'2 are transferred downstream by a predetermined distance, and the rotational drive is stopped. At this time, the discharge of the cut sheet Q from the conveyance roller 17 of the apparatus main body 1 is stopped.

(5) Next, as shown in FIG. 8(e), after the abutting guide 93 is again advanced downward with respect to the conveyance path, the cut sheet is removed from the conveyance roller 17 of the apparatus main body 1. The discharge of Q is resumed.

(6) Next, after the number of sheets Q stacked on the loading section 95 reaches the number of sheets to be sorted (sorting unit),
As shown in FIG. 8(f), after retracting the abutment guide 93 upward, the roller driving unit 40 rotates the plurality of rollers 94 to rotate the stacked cut sheets Q'1 after the stacking. , Q'2, and Q'3 are transferred downstream by a predetermined distance, and the rotational drive is stopped. At this time, only Q'1 is delivered from the collection and transfer section 91 to the placement section 83 (belt conveyor 86) of the stacker section 92. The belt conveyor 86 is rotated by the conveyor drive section 51 when the stacked cut sheets Q'1, Q'2, and Q'3 are transferred, and delivers the stacked cut sheets Q'1 from the accumulation and transfer section 91 to the stacker section 92. then stop. At this time, the discharge of the cut sheet Q from the conveyance roller 17 of the apparatus main body 1 is stopped.

(7) Next, as shown in FIG. 8(g), after the abutment guide 93 is again advanced downward with respect to the conveyance path, the cut sheet is removed from the conveyance roller 17 of the apparatus main body 1. The discharge of Q is resumed.

(8) Next, after the number of sheets Q loaded on the loading section 95 reaches the number of sheets to be sorted (sorting unit),
As shown in FIG. 8(h), after the abutting guide 93 is retracted upward, the plurality of rollers 94 are rotationally driven by the roller drive section 40, and the stacked cut sheets Q'2 after being stacked are Q'3 and Q'4 are transferred downstream by a predetermined distance and the rotational drive is stopped. At this time, only Q'2 is delivered from the collection and transfer section 91 to the placement section 83 (belt conveyor 86) of the stacker section 92. The belt conveyor 86 is driven by the conveyor driving section 51 to rotate the stacked cut sheets Q'2, Q'3, and Q'4 during transfer, and the stacked cut sheets Q'2 are transferred from the accumulation transfer section 91 to the stacker section 92. Stops after delivery. At this time, the discharge of the cut sheet Q from the conveyance roller 17 of the apparatus main body 1 is stopped.

The accumulation and transfer section 91 and the stacker section 92 are configured to be driven independently of each other, and the gap X1 between the stacked sheets Q' on the accumulation and transfer section 91 and the stacked sheets on the stacker section 92 are separated. The gap X2 between Q′ is specifically controlled by the roller drive unit 40 and the conveyor drive unit 51 via the control unit 45. Roughly speaking, X1 is a gap equal to the thickness of the abutment guide 93 plus an allowance for the abutment guide 93 to move back and forth smoothly, and may be a gap of about 10 mm. Regarding X2, it is the gap necessary for the operator to easily take out the stacked sheets on the belt conveyor, and the approximate gap is about 20 mm to 50 mm. The relationship between the two is X1<X2, and the transport speeds V1 and V2 of the stacked sheets Q' of the stacking and transferring section 91 and the stacker section 92 also have a relationship of V1<V2. That is, when transferring (shifting) the stacked cut sheets Q' from the stacking transfer section 91 to the stacker section 92, control is performed to accelerate the conveyance speed and widen the gap from X1 to X2. In the embodiment, the number of stacked cut sheets Q' lined up on the accumulation and transfer section 91 has been described as three, but the number is not limited to this and may be one or three or more. Furthermore, although the number of stacked sheets Q' arranged on the stacker section 92 has been described as two, it is not limited to this, and may be one or two or more.

According to the above, as long as the minimum gap X1 between the stacked paper sheets Q' on the stacking transfer section 91 is secured, all that is needed is to transfer the stacked paper sheets Q' to the stacker section 92 while shifting them. Since the control to widen the space to the gap X2 from which the material can be easily taken out is automatically performed independently of the accumulation and transfer section 91, the stop time of the accumulation and transfer section 91 can be kept to the necessary minimum, resulting in high work efficiency. . In the conventional technology, the discharged cut sheets Q are stacked on one (one drive) belt conveyor every predetermined number of sheets and are transferred to the downstream side with a predetermined gap. Until a predetermined gap is opened, loading work (discharging work) for subsequent discharged paper must be stopped while the preceding paper is being transferred (while the belt conveyor is running), which reduces work efficiency.
