Description

[Detailed description of the invention] (Industrial application field) In the invention, a tape is wound around paper sheets sandwiched at a binding position, and the tape ends are cut and thermally bonded to bind the paper sheets. The present invention relates to an apparatus for binding paper sheets.

(Conventional technology) In paper sheets such as banknotes, a predetermined number of sheets are bound as one bundle. For this bundling, a device is used in which a predetermined number of sheets conveyed one by one are stacked in a stacking unit, and the sheets are transported to the binding unit and bound by a tape. A tape is wrapped around the paper sheet sandwiched at the position, the tape is tensioned, the blade is pressed against the tape in a state where the paper sheet is tied, and the cut end is heated with a trowel for heat bonding. It is made to adhere with.

(Problems to be solved by the present invention) However, in the above-described conventional tape cutting, the tape is cut by pressing the blade in a state where the tape is tensioned and the paper sheets are tied. Cut, and then it is cut off from the cut by the tensile force applied to the tape until it cuts,
Therefore, it is cut by shredding with a tensile force rather than cutting with a blade, and if the cut end is stuck, it can not be cut cleanly, and even after bundling, the cut end is exposed and the appearance of bound paper sheets is significantly impaired. Becomes

In view of the above, the present invention provides a tape suitable for cutting at the time of cutting the tape after being wound around the paper sheet, so that the cut edge is not cut off, and the cut sheet can be cut cleanly. To provide a binding device.

(Means for Solving the Problems) In order to solve the problems of the above-described conventional technology, the present invention is to wrap a tape around an outer periphery other than a holding portion of paper sheets held at a binding position, and to wind the tape. After the tape is wound, the tape winding portion is pressed and tightened with the right and left clamp members, and the tape is tightened. A tape supply means having a body, a drive motor for rotating the tape supply rotating body in a normal rotation drive for tape feeding and a reverse rotation drive for tightening the tape after tape winding, and near the one clamp member. After waiting for the tape on the paper sheet having the center of rotation and being clamped between the clamp members, the tape advances to the lower corner of the paper sheet and turns, and the receiving portion at the leading end presses the tape at the corner of the paper sheet. Maintain the tightened state A tape pressing means comprising a lower support lever, a cutter mechanism for cutting the tape pressed by the tape pressing means, and a drive motor rotated forward by a predetermined amount before the tape is cut by the cutter under the pressing state by the tape pressing means. And a controller for relaxing the tension of the tape and controlling the tension to be suitable for cutting the tape.

(Operation) After the tape is wound around the paper sheet sandwiched at the binding position, the tape is tightened by the reverse rotation of the tape supply rotating body to bind the paper sheet. After maintaining the attached state, the tape supply rotating body is rotated forward by a predetermined amount to loosen the tape between the tape pressing means and the tape supply means, and a cutter is applied to this portion to push it off. As a result, since no tension acts on the tape, the tape is cut by the cutter, so that the tape does not stand up.

To rotate forward by the set pulse.

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

In FIGS. 1 and 2, bills P to be bound are placed on the hopper 6 of the binding machine 1, and when a start button is pressed, the bills are fed into the machine one by one by a not-shown feeding means. The fed banknote is identified by the identification unit 8 as to whether or not it is a banknote suitable for binding.
In the case of non-conforming banknotes such as different denominations, false banknotes, and two-ply banknotes, the branch pieces 10 are switched by a signal from the identification unit 8 and returned to the reject unit 7. The bills fed to the stacking unit 11 enter the receiving member 18 one by one between the blades 30 and 30 of the impeller 26, are sent to the receiving member 18, are left on the bottom 24 thereof, and sequentially stand on the bottom 24 in the standing posture. It is aligned and collected. Meanwhile, the intermittent drive of the longitudinal alignment mechanism 32 causes the aligning rod 42 to pivot and hit one end in the longitudinal direction of the bill P, push the other end of the bill P toward the fixed wall 31 side, and accumulate while accumulating in the longitudinal direction.
At the same time, the short-side direction aligning mechanisms 43, 43 operate intermittently, and the aligning members 46, 46 rotate to push the upper and short sides of the banknote P by the aligning portions 46a, 46a to perform short-side aligning. It is.

As shown in FIG. 16A, a predetermined number of sheets (usually 100
When the banknotes P are stacked in an aligned state,
The machine base 65 rises via the belt 73 by the drive of the 12 motors 68,
When the left and right pinching claws 52 and 53 are opened, they rise and advance to a position near one end in the longitudinal direction of the stacked banknotes P in the stacking section 11 and
Claws 52, 53 pinched by the rotation of cams 59, 63 which rotate by the rotation of 68
Approach and pinch the banknote P between the pinching claws (FIG. 16 (B)).

After the bills are clamped, the swing lever 20 swings clockwise about the shaft 21 by rotation of the cam 23, and the receiving member 18
The motor 142 of the tape winding means 15 is activated at the same time as retracting from the lower portion of the tape winding means 15, and the turning arm 119 starts turning through the gears 141 and 132, whereby the cam follower 112 of the movable holding member 116 falls from the cam portion 124, and the movable holding member 116 Spring 1
The tape T is closed by the bias of 21 and the tape T protruding from the leading end of the tape passage 111 is held between the leading 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. As a result, the pulled out tape T
Is sagged so as to cross the position where the bill P descends (the binding position A). Then, the machine 65 of the holding and transferring means 12
Then, the banknote P starts moving again, and the banknote P is moved to the binding position A (FIG. 16 (D)). The pressing plate 27 of the stacking unit 11 moves forward because the bills P have run out, and returns to a position in contact with the peripheral surface of the impeller 26.

Next, the one clamp member 83 having the tape guide 107 of the clamp means 13 advances in advance (FIG. 16 (E)), and the tape T on the clamping end side pulled out by the tape winding means 15 is moved to the tape guide 107. Guide pieces 106,106
The tape T is guided in between, and the position of the tape T is regulated.

Thereafter, the sandwiching members 115 and 116 are further rotated, and the tape T is wound around the banknote P once. At this time, when the tape T passes through the leading end of the tape passage 111 of the tape supply means 14, that is, passes through the fixed position in FIG. 16 (A). When the cam follower 122 of the movable pinching member 116 rides on the cam portion 124, the tape T is released from being pinched, so the solenoid is used at the second passage.
126 operates to pull the cam member 123 to escape the cam portion 124, and the cam follower 122 of the movable pinching member 116 does not interfere with the cam portion 124, and therefore passes while the tape T is pinched. Then, when the holding members 115 and 116 rotate one or more turns to reach a position where a part of the tape T overlaps (FIG. 16 (F)), the tape winding means 15 stops.
Thereafter, the right and left clamp members 83 and 84 advance together toward the binding position A by the action of the cams 90 and 105, and clamp the other end of the bill P pinched by the pinching claws 53 and 54 of the pinching transfer means 12. As a result, the tape T is stored inside the clamp members 83 and 84 (FIG. 16 (F)). Next, the motor 114 of the tape supply means 14 is reversed 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 thereafter slips, so that the tape T binds the bill P with a fixed tightening force. After that, the motor 114 is rotated forward by a predetermined number of pulses, and the tape T is fed out by a fixed amount to slightly reduce the tightening force of the tape T.

Then, the cam 161 of the iron mechanism 17 rotates, and the arm 155 is pivoted.
When the lever 162 is rotated clockwise in the drawing around the center 154, the receiving portion 163 of the lower support lever 162 hits the lower end corner of the tape T wound around the banknote P and presses it, and the lever 158 enters the clamp member 82. It comes into contact with the overlapping portion of the tape T wound first (FIG. 16 (G)), and the heat bonding of the tape T is started.

Thereafter, the motor 114 of the tape supply means 14 rotates forward by a predetermined pulse to give the tape T slack, the cutter mechanism 16 is operated, and the cutter 146 comes into contact with the tape T (FIG. 16 (H)).
Cutting is performed. After the cutting, the iron 158 further advances, and the cut end of the tape T is adhered (FIG. 16 (I)).

After the tape is cut, the motor 133 of the tape winding means 15 is driven, and the movable frame 117 moves backward (to the left in FIG. 13) via the lever 136 and the swing arm 138, whereby the gear 132 meshes with the gear 141. Then, the user slides and pulls the shaft 118, pulls out the pinching members 115 and 116, and pulls out the bill T from under the tape T wound around the bill P. Then the stamp 91 moves forward and the tape T
A predetermined seal is made on the surface of the.

When the bonding of the tape T is completed, the iron 158 returns (No. 16).
((J)), simultaneously, the pinching claws 52, 53 of the holding and transferring means 12 separate to release the holding of the bill P, and then the clamp members 82, 83 of the clamping means 13 separate to move the bound bill P downward. After discharging, all the parts return to the state shown in FIG. 16 (K) to FIG. 16 (A), and the bound banknotes P are appropriately collected in the receiving box.

Although the illustrated embodiment has been described for the case of banknote binding, it is needless to say that the present invention 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 appropriately change the design. The timing of the thermal bonding of the tape T may be either one in which the thermal bonding is started after the tape is cut, or one in which the thermal bonding is started before the tape is cut, and the tape T is continuously heated and the cut end of the tape T is heated. It may be. Further, the timing for releasing and holding the sheets at the binding position A by the pincers 52 and 53 may be earlier or later than the time for releasing the clamp of the sheets by the clamp members 82 and 83.

Next, as another embodiment of the present invention, a case of a banknote binding machine that only binds banknotes will be described.

In this embodiment, the operator inserts and accumulates the aligned banknotes into the binding position A by hand and clamps them, and when the binding is completed, the operator manually pulls out the bound banknotes from the binding position A outside the machine. As described above, the operator holds the untied bills by hand during the binding operation, so that the mechanism (reference numerals 6, 7,
There are no parts indicated by 8, 9, 10 and 11)
Although it does not have 12, it has all the other components (portions indicated by reference numerals 13, 14, 15, 16, 17) as they are.

A specific example of this embodiment is shown in FIGS. 18 and 19. In this embodiment, a bill insertion and holding device 200 is provided, and other components (reference numerals 13, 14, 15, 16, and 17) are It is exactly the same as the previous embodiment.

The bill insertion and holding device 200 has a bill insertion slot 201 having a width larger than the thickness of the unbound bill bundle P ′.
Is open at the top, so that it can be dropped down and inserted. A back stopper 202 is provided which presses the end of the unbundled banknote bundle P 'inserted into the banknote insertion slot 201 to determine the insertion position. The back stopper 202 is fixed to a rotary arm 204 fixed to the rotary drive shaft 203, and the time to wait for insertion of the unbound banknote bundle P 'into the insertion slot 201 is the position shown in FIG. When the winding means 15 rotates, the winding means 15
Rotary drive shaft 203 and rotary arm 20 so as not to interfere with 202
The back stopper 202 is retracted to the non-interfering position by the rotation of the predetermined angle of 4.

Therefore, in this embodiment, the motor 142 of the tape winding means 15 is started by manual operation of a power switch or a separately provided set switch, and the tape T is clamped so that the tape winding means 15 is moved from the position shown in FIG. Move to the position shown in FIG. 18 and stop. The state shown in FIG.
Corresponding to FIG. (C), the position of the tape wrapping means 15 is the same position in FIGS. 16 (C) and 18. Immediately thereafter, the back stopper 202 rotates from the retracted position and temporarily stops at the position shown in FIG.

In this state, the operator inserts the bundle of untied bills P '(for example, 100 bills of a predetermined denomination bill) into the insertion slot 201 while holding the bundle. In this case, the unbundled banknote P 'is inserted into the insertion slot 201 at a slightly upper position (the position shown by the two-dot chain line in FIG. 18, that is, the upper position not in contact with the tape T), and the end of the unbundled banknote P' Against the back stopper 202.

Then, while holding the bill bundle P 'by hand, it is lowered downward along the opening edge 201a of the insertion slot 201, and
01a is hit with an unbound banknote bundle P '(FIG. 18 and FIG. 1).
9) (corresponding to FIG. 16 (D)). At this time, there is a gap between the unbound banknote bundle P 'and the opening edge 201c.

When the lower edge of the unbound banknote bundle P 'comes into contact with the opening edge 201b, a detection switch (not shown) detects the banknote bundle P' and moves the back stopper 202 to the retracted position.

Next, one clamp member 83 having the tape guide 107 of the clamp means 13 advances ahead (FIG. 16 (E)).
16) (F), (G), (H), (I),
By performing the same operation as in (J) and (K), the clamp members 82 and 83 are separated from each other. The separation of the clamp members 82 and 83 is displayed to the operator by, for example, a lamp, and the operator inserts the bundled banknote bundle into the
Pull out from one. The detecting means (not shown) detects the removal of the bill bundle and performs the corresponding operation shown in FIGS. 16 (B) and (C), and the tape winding means 15 is placed at the position shown in FIG.
On the other hand, the back stopper 202 also advances from the retracted position to the position shown in FIG. 19 again by the rotation of the rotary drive shaft 203, and waits for the insertion of the next bundle of unbound banknotes P '.

As described above, according to the present invention, the initial bundling can be performed even when the unbundled banknote bundle is pinched by hand.

[Effect of the invention]

As described above, according to the present invention, after the tape is wound around the paper sheet sandwiched at the binding position, the tape is tensioned by applying tension to the tape, and then wound around the paper sheet after tightening. After pressing the tape by the tape pressing means, the tape supply rotating body is rotated forward by a predetermined amount to loosen the tape between the pressing position by the tape pressing means and the tape supply means, and the cutter is pressed against this range to press the tape. As the tape is cut into the cutter, the tape fits into the cutter and is cut.Therefore, there is no shredging of the tape, and the cut edge is cut cleanly without sticking, which may impair the appearance of the bound paper sheets after binding. Absent.
