A rear end of the piece 95 is connected to a plunger of a solenoid 99 mounted on the holding piece 87, and the solenoid 99 is operated to advance from the upper surface of the holding piece 87 to the position shown by the chain line in FIG. A cam follower 100 is axially attached to the rear end of the holding piece 96 of the lower holding piece 88, and the holding piece 96 is protruded to the side of the holding piece 88 as shown by the solid line in FIG. The cam follower 100 hits the cam 101 and is swung to the position shown by the chain line in FIG.

Next, the operation of the above embodiment will be described with reference to FIGS. 5 (A) to 5 (C) and FIGS. 6 (A) to 6 (C).

The predetermined number of paper sheets fed onto the stacking plate 71 of the paper sheet stacking unit 70 are stacked by the side surface 73 b of the rotating plate 73.

Then, the machine frame 82 is moved forward (rightward in FIG. 1) via the bell 84 by the rotation of the motor 83, and the sandwiching pieces 87 and 88 are inserted into the window hole 74 of the rotating plate 73 of the stacking unit 70. , 74 and the cutouts 75, 75 of the stacking plate 71.

Here, the rotation of the motor 89 raises the lower sandwiching piece 88 via the belt 90 and lowers the lever 94 to lower the upper sandwiching piece 87 via the parallel links 93, 93. At this time, the holding piece 95 attached to the upper holding piece 87 is stored in the holding piece 87 at that position, and the holding piece 96 of the lower holding piece 88 is in a state of protruding laterally.

Due to the approaching movement of the upper and lower holding pieces 87, 88, the holding pieces 87, 88 are moved from the window holes 74, 74 of the rotating plate 73 of the stacking unit 70 and the cut holes 75, 75 of the stacking plate 71 to the inside of the stacking unit 70. And the position near one end of the sheet P group accumulated in the accumulating unit 70 is pinched.

The hanging and splashing of class P is suppressed.

After the paper sheet P group is sandwiched in this way, the sandwiching pieces 87 and 88 move backward in the opposite operation to take out the paper sheet P group to the outside of the stacking unit 70 and to remove the paper sheet P group from the stacking unit 70. The pinching end side is inserted between the first and second pinching members 2 and 3 of the paper sheet pinching means 1. In this way, the upper and lower presser pieces 95, 96 are carried into the bundling section 1 which holds the non-holding end of the sheet P group in a state of protruding, and immediately after that, the cam follower 100 of the holding piece 96 of the holding piece 88 causes the cam 101 to move. Then, due to this, the pressing piece 96 is retracted to the position of the clamping piece 88, and the pressing piece 95 of the upper clamping piece 87 is also retracted by the solenoid 99.

When the pressing pieces 95 and 96 have moved out, the conveyance of the sheet P group is completed.

On the other hand, the tape T supplied from the tape supply means is supplied between the arms 31a and 31b of the tape winding means 30, and the solenoid 59 of the tape winding means 30 is excited to move the moving member 60. When the cam 61 escapes, the movable arm 31b is closed by the biasing force of the spring 57, the fixed arm 31a and the movable arm 31b sandwich the tape T, and then the gear 38 is driven to form the gear 37 meshing with this. The rotating arm 36 is rotated, and the arm 31 holds the tape T, and the arm 31 reaches the standby position indicated by the symbol C in FIG. At this time, the feeding of the tape T by the tape feeding means leaves the tape T slackened at the position where the paper sheets are inserted.

When the arm 31 turns to the C position, the tip of the arm 31 contacts the flange 4c of the tape guide member 4 and pushes it up, and the tape T held and guided by the arm 31 is the tape guide member 4. It is placed between the guide surfaces 4a, 4a of the (FIG. 5 (B)). In this state, the group of paper sheets P is fed in as described above.

As the arm 31 is further swung, the tip of the arm 31 reaches a position in contact with the lower surface of the paper sheet P as shown in FIG. 5C, and the tape T is wound around the paper sheet P roughly once around one round. It will be attached. At this time, following the downward rotation of the arm 31, the tape guide member 4 also follows the guide surfaces 4a, 4a while the tape T is housed in between, thereby preventing the tape T from shifting laterally. .

At this time, the cam member 11 of the paper sheet sandwiching means 1 moves to the left in FIG. 2, and the cam surface 11a of the first sandwiching member 2 is connected via the arm 7 to the cam surface 11b of the link 15, The second holding members 3 are moved closer to each other via 16 to hold the paper sheet P (FIG. 6A). At this time, the free end 4b of the tape guide member 4 hits the paper surface of the paper sheet P and is gradually pushed, and is fitted between the holding surfaces 1a, 1a of the first holding member 1, while the guide action of the tape T is exerted during that time. Continuing, the shifting movement of the tape T is prevented.

Next, the tape T is pulled back by the action of the tape supply means to give tension, and after the winding is tightened, the iron 66 advances and presses the overlapping portion of the tape T, and the cutter 65 Advances and cuts the tape T (Fig. 6 (B)).

After the tape T is cut, the trowel 66 slides to thermally bond the cut end of the tape T, and the cam member 11 moves to the right in FIG. 2 and 3 are separated from each other (FIG. 6C), and the bundle of paper sheets that has been bundled is discharged to finish the bundle.
