On the shaft 154 of the arm 155, another lower support lever 162 as a tape pressing means is attached, and the receiving portion 163 at the tip thereof hits the lower end of the tape T wound around the banknotes at the bundling position A to form the tape. It is structured so that T does not loosen.

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

1 and 2, when the banknotes P to be bound are placed on the hopper 6 of the binding machine 1 and the start button is pushed, the bills are fed into the machine one by one by the feeding means (not shown). The bills carried in are discriminated by the discriminating unit 8 as to whether or not the bills are suitable for bundling.
In the case of non-conforming banknotes such as different denominations, fake banknotes, and two-ply banknotes, the branch piece 10 is switched by the signal from the identification section 8 and returned to the reject section 7. The banknotes sent to the stacking unit 11 are inserted between the blades 30 and 30 of the impeller 26 one by one and sent to the receiving member 18, and are squeezed and left on the bottom 24 thereof in a standing posture. Aligned and accumulated. In the meantime, the aligning rod 42 is swung by the intermittent drive of the longitudinal direction aligning mechanism 32 to hit one end of the banknote P in the longitudinal direction, and the other end of the banknote P is pushed toward the fixed wall 31 side to proceed the stacking while the longitudinal direction is aligned.
At the same time, the transverse direction aligning mechanisms 43, 43 are operated intermittently, and the aligning members 46, 46 rotate and push the upper ends of the banknotes P by the aligning portions 46a, 46a to perform the transverse direction alignment. .

As shown in FIG. 16 (A), a predetermined number of sheets (normally 100
When the (sheets) of banknotes P are accumulated in an aligned state, the pinching and transferring means
Driven by the motor 68 of 12 raises the machine base 65 via the belt 73,
The left and right sandwiching claws 52, 53 rise until they open and move to a position near one end in the longitudinal direction of the stacked banknotes P in the stacking unit 11,
Rotate by 68 Rotate by cam 59,63 Rotate by cam 52,53
Approach each other and hold the banknote P between the two sandwiching claws (FIG. 16 (B)).

After the banknotes are clamped, the swing lever 20 swings clockwise around the shaft 21 by the rotation of the cam 23, and the receiving member 18 moves the banknote P.
The motor 142 of the tape winding means 15 is activated at the same time when the tape winding means 15 is retracted, and the swivel arm 119 begins to swivel through the gears 141 and 132. As a result, the cam follower 112 of the movable pinching member 116 falls from the cam portion 124, and the movable pinching member 116 moves. Spring 1
It is closed by the urging force of 21, and the tape T protruding from the tip of the tape passage 111 is held between the ends of the fixed holding member 115 and the movable holding member 116. Thereafter, the revolving arm 119 further revolves, and temporarily stops at the position shown in FIG. 16 (C), that is, at about 3/4 round. By this, the tape T pulled out
Is slackened so as to cross the position where the banknote P descends (bundling position A). Next, the machine base 65 of the pinching transfer means 12
Starts to descend again, and the banknotes P are moved to the bundling position A (FIG. 16 (D)). The pressing plate 27 of the stacking unit 11 has moved forward because the banknotes P have disappeared, and has returned to the position in contact with the peripheral surface of the impeller 26.

Then, the one clamp member 83 having the tape guide 107 of the clamp means 13 is advanced and advanced (FIG. 16 (E)), and the tape T on the side of the nipping end pulled out by the tape winding means 15 is moved to the tape guide 107. Guide piece 106,106
It is guided between and the position of the tape T is regulated.

After that, the sandwiching members 115 and 116 further rotate to wind the tape T around the bill P, but at this time, when passing the tip of the tape passage 111 of the tape supply means 14, that is, past the fixed position in FIG. 16 (A). At this time, when the cam follower 122 of the movable pinching member 116 rides on the cam portion 124, the pinching of the tape T is released, so the solenoid is used at the second passage.
When 126 operates, the cam member 123 is pulled to release the cam portion 124, and even if the cam follower 122 of the movable pinching member 116 comes around, it does not interfere with the cam portion 124, and thus the tape T is passed while being pinched. The tape winding means 15 stops when the holding members 115, 116 rotate one or more turns and reach the position where the tapes T partially overlap (FIG. 16 (F)).
After that, the left and right clamp members 83, 84 both advance toward the bundling position A by the action of the cams 90, 105, and clamp the paper money P clamped by the clamping claws 53, 54 of the clamping transfer means 12 near the other end. As a result, the tape T is stored inside the clamp members 83, 84 (FIG. 13 (F)). Then, the motor 114 of the tape supply means 14 is rotated in the reverse direction for a predetermined time to apply tension to the tape T. At this time, when the tension of the tape T reaches a certain amount due to the friction between the tape surface and the roller 113, the roller 113 slips thereafter and the tape T binds the banknote P with a constant tightening force. After that, the motor 114 is rotated in the normal direction by a predetermined pulse, and the tape T is fed out by a fixed amount, so that the tightening force by the tape T is slightly weakened.

Then, the cam 161 of the trowel mechanism 17 rotates and the arm 155 is rotated.
154 is rotated clockwise in the figure, and the receiving portion 163 of the lower support lever 162 hits and presses the lower end corner of the tape T wound around the banknote P, and the lever 158 enters the clamp member 82. The tape T, which has been wound first, comes into contact with the overlapped portion (FIG. 16 (G)), and the tape T is thermally bonded.

After that, the motor 114 of the tape supplying means 14 rotates forward by a predetermined pulse to loosen the tape T, the cutter mechanism 16 operates, and the cutter 146 comes into contact with the tape T (Fig. 13 (H)).
A disconnection is made. After cutting, the trowel 158 advances further, and the cut end of the tape T is bonded (FIG. 16 (I)).

After the tape is cut, the motor 133 of the tape winding means 15 is driven to move the movable frame 117 backward (leftward in FIG. 13) via the lever 136 and the swing arm 138, whereby the gear 132 meshes with the gear 141. Only then slide to pull the shaft 118, pull the sandwiching members 115 and 116, and pull out from the bottom of the tape T wound around the banknote P. After that, the stamp 91 advances and a predetermined imprint is made on the surface of the tape T.

When the tape T is completely attached, the iron 158 returns (16th
(J)), at the same time, the sandwiching claws 52 and 53 of the sandwiching and transferring means 12 separate from each other to release the holding of the banknotes P, and then the clamp members 82 and 83 of the clamp means 13 separate to separate the bundled banknotes P downward. After discharging, all the parts return from the state of FIG. 16 (K) to the state of (A), and the bundled banknotes P are appropriately collected in the receiving box.

Although the illustrated embodiment has been described for the case of binding banknotes, it is needless to say that it can be applied to the binding of other paper sheets, and the configuration of each part is not limited to the illustrated embodiment. It is optional to change the design appropriately. Further, the timing of heat-bonding the tape T is either one in which heat-bonding is started after the tape is cut, or one in which heat-bonding is started before the tape is cut and the heat-bonding is continued after the tape is cut and the cut end of the tape T is heat-contacted. May be Further, the holding and releasing timing of the paper sheets at the binding position A by the sandwiching claws 52, 53 may be earlier or later than the clamp releasing timing of the paper sheets by the clamp members 82, 83.

[Effect of device]

As described above, according to the present invention, the tape is wound around the outer periphery other than the region where the paper sheets are clamped at the binding position, and the vicinity of the wound region is clamped by the first and second clamp members. With this structure, it is not necessary to wrap the tape around the holder as in the prior art, and the bundled paper sheets can be discharged simply by releasing the clamping by the clamp member after binding, which may damage the paper sheets. Since the paper sheets are clamped and sandwiched by the left and right contact edges of the clamp member, the tape can be wound in a tightened state.

In particular, the tape can be wound around the paper sheet by the guide portion provided on one clamp member without shifting in the left-right direction, and the winding end sticks out to the side of the tape after binding, resulting in an unsightly form. Without such a situation, various effects can be obtained such that a bound paper sheet having a good appearance can be obtained.
