Next, the operation of the above embodiment will be explained.

In Figure 2, the rotating wheel 2 is in the fixed position and the paper sheet P
is placed between the press holding plates 29 and 30, and the divider 2
6 shows the state in which it is inserted between the leaves.

At this time, the claw portion 18a of the stop member 18 is engaged with the stepped portion 20 of the rotary ring 2, and at the same time the pressing portion 2
1 presses the pin 13 of the swinging arm 11 to separate the second roller 9 at the other end from the first roller 8,
In addition, one end 15a of the locking member 15 is arranged to engage with the recess 14 to immovably restrain the swing lever 11 in that position.

In the state shown in FIG. 2, when a start signal is issued, the tape insertion plate 27 moves upward, lifts the tape T, and inserts the tape T in a folded state between the sheets P which are being spread apart by the divider 26. do. At the same time, the edge of the tape insertion plate 27 comes into contact with the rear end edge of the divider 26 and pushes it against the shaft 2.
Rotate using 8 as a fulcrum and remove it from between the leaves. As a result, the leaves are crimped and the tape T is sandwiched together with the insertion plate 27.

When the tape insertion plate 27 descends, the tip of the tape T folded in two remains between the leaves, and the edge of the insertion plate 27 separates from the divider 26, so the divider 26 tries to return due to the action of the spring. , since the interleaf space is already closed, the paper leaf P
It is held in contact with the bottom surface of.

After that, links 31 and 32 are connected by a cam (not shown).
The press holding plates 29 and 30 press and hold the paper sheet P via the press and hold plates 29 and 30. At the same time, the stop member 18 is rotated counterclockwise in the figure about the shaft 19 by a cam (not shown), and the claw portion 18a of the stop member 18 is removed from the stepped portion 20, so that the rotation wheel 2 is released from the restraint. With this withdrawal of the stop member 18, the pressing portion 21 is also separated from the pin 13 of the swing arm 11. However, as the pressing plate 21 moves away, the swinging arm 11 tries to follow the rotation due to the action of the spring (not shown), but because the one end 15a of the locking member 15 is engaged with the recess 14 as described above, The person is placed in the position shown in Figure 2. Therefore, the swinging arm 11
The upper second roller 9 remains spaced apart from the first roller 8 on the rotating wheel 2.

After that, the drive source 6 is activated and the gear 7 is rotated.
The rotating wheel 2 is rotated in the direction of the arrow. Due to this rotation, the tape T is picked up and supported by the outer periphery of the first roller 8 and moves upward on the left side of the paper sheet P as shown in the third figure. In this case, even though the tape T passes between the first and second rollers 8 and 9, the rollers 8 and 9 are separated, so no tensile force is applied to the tape T, and as a result, , there is no risk that the tip inserted between the leaves of the tape T will slip out.

As the rotation of the rotary wheel 2 progresses in this way, the tape T
is bent by the lower left outer corner and the upper left outer corner in the diagram of the paper sheet P, and has frictional resistance. Next, the pin 16 of the locking member 15 hits the inclined surface 17a of the unlocking member 17, and due to the inclination, the pin 16 of the locking member 15 is gradually rotated counterclockwise, and the one end 15a of the locking member 15 is rotated counterclockwise.
It comes off from the recess 14 of No. 1.

This releases the restraint on the swinging arm 11, so the arm 11 rotates counterclockwise about the shaft 12 under the action of the spring, and the second roller 9 at the tip moves to the first roller of the rotating wheel 2. The tape T is held in contact with the roller 8 (as shown in the fourth figure).

After the tape T is held between the first and second rollers 8 and 9 in this manner, the tape T is strongly pulled and wrapped, thereby tightening the paper sheet P. In this case, even if the tape T is strongly pulled as described above, the tape T has already been bent along at least one outer corner, that is, two outer corners of the paper sheet P in this embodiment. Therefore, the tensile force does not directly reach the tip of the tape T sandwiched between the leaves, and as a result, the first and second rollers 8,
Even after being held at 9, the tip of the tape T does not slip out from between the leaves.

As described above, when the tape T is held between the first and second rollers 8 and 9, the detector 23 detects the detection object 22, and the detection signal excites the solenoid 38 to move the cutter 25 downward. Cut the tape T.

Thereafter, the tape T slides between the first and second rollers 8 and 9 to follow the rotation of the rotary wheel 2, and when the detection object 22 reaches the detector 24 in the second rotation, the tape T slides between the first and second rollers 8 and 9. The drive source 6 is stopped by the detection signal, and the rotating wheel 2 is also stopped.

At this time, the claw portion 18a of the stop member 18 has been previously positioned on the circumferential surface of the rotating ring 2 by a cam (not shown), and the claw portion 18a drops into the stepped portion 20 to lock the rotating ring 2 in a fixed position. Further, when reaching this fixed position, the pin 13 of the swinging arm 11 hits the pressing part 21, and the swinging arm 11 is rotated clockwise around the shaft 12 to move the second roller 9 away from the first roller 8. Separate. Due to the above-mentioned rotation of the swing arm 11, the one end 15a of the lock member 15 fits into the recess 14, and the swing arm 11 is restrained in the state shown in FIG. 2 and returned to its initial state.

When the winding of the tape T is completed as described above, adhesion is performed in a known manner, and then the press holding plates 29 and 30 are opened and the bundled paper sheets P can be removed.

〔Effect of the invention〕

As explained above, the present invention has a tape supporting member that clamps a tape to be wrapped around a paper sheet, and is configured to clamp the tape after the tape is bent along at least one outer corner of the paper sheet. Therefore, no tensile force is applied to the tape in the initial stage of winding the tape, so there is no inconvenience such as the tip of the tape inserted between the leaves slipping out and coming off, and the tape is not attached to the outside of at least one of the paper sheets. Since the tape is sandwiched between the supporting members after being bent by the corner, the insertion tip of the tape will not come off even if a strong tensile force is applied, and therefore paper sheets can be bound in a tight state. can.

In this embodiment, rollers 8 and 9 are used as tape support members, but these are not limited to rollers and may be replaced with other non-rotating members, and the position where the tape T is held may be , the tape T may be bent along the three outer corners of the paper sheet P. Furthermore, other configurations are not limited to this embodiment, and other design changes may be made as desired.
