BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for band-bonding a plurality of paper sheets in a bound state, and more particularly to an apparatus capable of greatly simplifying and downsizing the configuration. Further, the present invention relates to a device in which the banding tightness of a bundle of paper sheets can be freely adjusted.

2. Description of the Related Art Banknote banding devices for banding banknotes in a bundle are widely used in banks and the like. FIG.
It is a perspective view showing one example of composition of a bill bandage device conventionally used. In the conventional example of FIG. 4, a banknote bundle N of, for example, 100 sheets is inserted between the fixed clamp support 2 and the movable clamper 3 in the A direction, and is placed on a banknote support table (not shown for clarity). Supported. This banknote bundle N is divided into two parts by the separating sesame 4 located between the clamp support 2 and the clamper 3 in the substantially middle part (for example, between the 50th banknote and the 51st banknote). Inserted in. The banding tape T is passed through the separating sesame 4, and as a result, the banding tape T passes through the substantially central portion of the inserted banknote bundle N. Next, the separating sesame 4 is fed from the banknote bundle N to B.
After retreating in the direction, the clamper 3 moves in the direction of the clamp support 2, whereby the banknote bundle N is firmly clamped between the clamp support 2 and the clamper 3 with the band-sealing tape T sandwiched therebetween. It

When the clamping of the banknote bundle N is completed in this way, the tip end portion of the band-sealing tape T is sandwiched between the chuck roller 5 and the chuck block 6. Thereafter, the rotary gear 8, together with the chuck roller 5, the chuck block 6 and the like, rotates around the bill bundle N in the counterclockwise direction in FIG. 4, whereby the banding tape T surrounds the bill bundle N. Is wound around. For example, the cutter 10 driven by a solenoid cuts the band-sealing tape T when the winding amount of the band-sealing tape T reaches a predetermined amount.

When the rotary gear 8 continues to rotate after the banding tape T is cut by the cutter 10, the leading end of the banding tape T cut as described above is held by the chuck roller 5 and the chuck block 6. , And the banding tape T wound around the banknote bundle N is loosened as it is, so in this example,
Immediately before the banding tape T is released from the sandwiched state, the pressing lever 12 driven by, for example, a cam presses the banding tape T to prevent the banding tape T from loosening. After that, the heater block 14 driven by, for example, a cam heat-seals the end portion of the band-sealing tape T, whereby the band-sealing process of the banknote bundle N is completed. In order to perform the heat sealing, for example, an adhesive is applied to the inner surface of the band-sealing tape T. Eventually, the movable clamper 3 retreats, whereby the banknote bundle N that has undergone the banding process can be taken out of the apparatus.

[0005]

However, in the above-mentioned conventional banknote banding device, the banknote band N to be banded is fixed, and the banding tape T is run around the banknote bundle N to fix the banknotes. Since the device is wound around the bundle N, the size of the device is considerably large. Further, a cutter 10 for cutting the band-sealing tape T, a holding lever 12 for pressing near the end of the band-sealing tape T, and a heater block 14 for heat-sealing the end of the band-sealing tape T,
Since they are provided separately from each other and are driven by respective separate drive mechanisms, the configuration of the device is considerably complicated and the manufacturing cost is high. Further, although the band-seal tape T is inserted between the banknote bundles N by using the separating sesame 4, since the separating sesame 4 and means for individually driving the separating sesame 4 are required, the structure of the device is further increased. Was complicated and the manufacturing cost was high.

Further, the banknote bundle N needs to be banded by the banding tape T with an appropriate degree of tightness (tightening degree), and the degree of tightness of such a banding tape T is a degree of preference that each user prefers. Usually there is. Therefore, in the conventional banknote banding device, for example, by mounting the chuck roller 5 in a state of being biased by a spring (not shown) having an arbitrary strength, the banding between the chuck roller 5 and the chuck block 6 is performed. The tip end of the tape T is elastically sandwiched so that the banding tape T is wound around the banknote bundle N. In this case, for example, if the spring is made strong, the holding force for holding the band-sealing tape T can be increased, so that the banknote bundle N has a high degree of tightness (that is, is relatively hard).
Can be banded. On the contrary, if the spring is weak, the holding force for holding the band-sealing tape T can be reduced, so that the banknote bundle N can be band-bonded with a small degree of tightness (that is, relatively loosely). However, in this case, since the spring force of one spring is constant, the tightness of the band-sealing tape T cannot be freely changed over a wide range, and one bill band-sealing device is versatile enough to meet the needs of many users. There were inconveniences such as not being able to cope.

The present invention has been made in view of the above points, and it is a first object of the present invention to provide a paper sheet band-sealing device capable of greatly simplifying and downsizing its configuration. A second object of the present invention is to provide a paper sheet banding device capable of freely adjusting the banding tightness of a paper sheet bundle.

[0008]

SUMMARY OF THE INVENTION According to a first aspect of the present invention, there is provided a paper sheet band-sealing device in which a reel means for sending and rewinding a band-sealing tape and a bundle of paper sheets to be banded are detachably clamped. Clamping means, a sheet winding bundle clamped by the clamping means is rotated with respect to the band-sealing tape, thereby rotating the band-wrapping tape around the sheet bundle, and the rotary winding. A heater block for pressing the band-sealing tape wound around the bundle of sheets by a rotating unit against the clamp unit to heat-seal it, and cutting the band-sealing tape heat-sealed by the heater block at a predetermined position. The cutter, the heater block and the cutter are integrally attached, and the heater block and the cutter come into contact with the band-sealing tape to form the tape. A working position, in which the heater block and the cutter is provided with a rotatable actuating lever between a non-operating position in which it separates from the bundling tape.

In this paper sheet banding device, the paper sheet bundle clamped by the clamping means is rotated with respect to the banding tape supported by the reel means.
The device can be significantly downsized as compared with the conventional case where the band-sealing tape is run around the clamped bundle of paper sheets. Further, a heater block for pressing the band-sealing tape to heat-seal it and a cutter for cutting the band-sealing tape heat-sealed by the heater block at a predetermined position are integrally attached to a rotatable actuating lever. In addition, since the function of pressing the band-sealing tape, the function of heat-sealing and the function of cutting are integrally performed by the rotation of the operating lever, the configuration of the device can be remarkably simplified.

According to a preferred embodiment, the clamp means detachably clamps the sheet bundle by moving at least one of them relative to the other.
The pair of clamp members is included, and the tip portion of the band-sealing tape is maintained between the pair of clamp members in the standby state before performing the band-sealing process. In this case, the bundle of paper sheets to be banded is inserted between the pair of clamp members so that the tip of the banding tape is positioned between the bundle of paper sheets and one of the clamp members, and thereafter, In the clamped state in which the front end portion of the band-sealing tape is clamped between the sheet bundle and the one clamp member, the rotary winding means rotates the band-sealing tape with respect to the band-sealing tape. With such a structure, it is possible to perform the work of holding the band-sealing tape at a predetermined position without using the separating sesame that has been conventionally used, and the structure of the device can be further simplified.

Control means for controlling the rotation direction and the rotation amount of the motor so that the band-sealing tape can be sent out from the reel means or the band-sealing tape can be rewound on the reel means in accordance with the degree of tightness. is there. In the paper sheet band-sealing device having such a structure, the band-tightness of the band-sealing tape can be variously changed only by controlling the rotation direction and the amount of rotation of the motor, so that a desired band-sealing band-tightness that differs depending on the user can be universally realized. .

According to a preferred embodiment, the control means causes the band-wrapping tape to be rewound by an amount corresponding to a desired degree of tightness when the band-wrapping tape is wound around the sheet bundle by a predetermined amount. It drives the motor. Further, the control means drives the motor in a forward direction so that the heater block presses the heat-sealing tape to heat-seal it so that the heat-sealing tape causes looseness between the heater block and the reel means. ,
After the cutter has moved forward with respect to the banding tape that has loosened due to the rotation of the actuating lever, the motor may be driven by a predetermined amount in the negative direction so that the banding tape is rewound while eliminating the looseness. Good. In this case, the cutter can cut the band-sealing tape by utilizing the tension of the band-sealing tape that is rewound while eliminating the looseness.

Further, in the above apparatus, the tip of the cutter is attached to the heater block in an inclined state via an adjusting bolt, and by tightening or loosening the adjusting bolt, It is preferable that the working relationship between the cutter and the heater block with respect to the band-sealing tape can be adjusted.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a schematic front view showing a configuration example of a bill banding device according to an embodiment of the present invention. In FIG. 1, the rotary gear 20 is driven by a motor or the like (not shown) and is rotatable in the counterclockwise direction in FIG. The fixed clamp support 22 is fixedly provided on the rotary gear 20. The slide clamper 23 is provided on the rotary gear 20 so as to be capable of reciprocating with respect to the clamp support 22. In this way, the clamp support 22 and the slide clamper 23 constitute a clamp means for detachably clamping the banknote bundle N.

In the banknote bundle to be banded (for example, a bundle of 100 banknotes) N, the space between the slide clamper 23 and the clamp support 22 has an upper guide U as shown in the drawing.
In the standby state aligned with the space between the lower guide L and the lower guide L, the guide is inserted into the space between the slide clamper 23 and the clamp support 22 while being guided by the guides U and L. The band-sealing tape T is sent out from the reel 24, which is a band-sealing tape supporting means, via a guide roller 26 and the like. In the standby state before performing the banding process (FIG. 1 shows this standby state), the leading end of the tape T is maintained between the slide clamper 23 and the clamp support 22. , Thereby, when the banknote bundle N is inserted, the banknote bundle N
And the slide clamper 23 are automatically guided.

Thereafter, the slide clamper 23 moves closer to the clamp support 22 as indicated by the arrow, whereby the banknote bundle N is firmly clamped between the slide clamper 23 and the clamp support 22, and the tape The tip of T is firmly held between the banknote bundle N and the slide clamper 23. With such a configuration, in the bill banding device according to this embodiment, the separating sesame (FIG.
It is possible to perform the positioning and sandwiching work of the band-sealing tape T without the need for the (4) in FIG. 4) at all, the configuration of the device can be simplified, and the cost of the device can be reduced.

When the banknote bundle N is clamped as described above and the front end portion of the tape T is clamped, the rotary gear 20 rotates in the counterclockwise direction in FIG. The banknote bundle N clamped between the slide clamper 23 and the clamp support 22 on the rotary gear 20 also rotates in the same direction. By the rotation of the banknote bundle N, the band-sealing tape T is wound around the banknote bundle N while being pulled out from the reel 24. When the tape T is wound around the banknote bundle N by a predetermined amount in this manner, the rotation of the rotary gear 20 is stopped by an arbitrary stopper (not shown).

In the conventional banknote banding device described above with reference to FIG. 4, the banding tape is run around the fixed banknote bundle, whereas in this embodiment the banknote bundle N is attached to the banding tape T. By rotating the bill bundle N
The band-sealing tape T is wound around. Therefore, the bill banding device according to this embodiment can effectively reduce the size of the device as compared with the conventional device. However, in the band-sealing device according to this embodiment, since the banknote bundle N is rotated, the pressing lever (which is conventionally used to prevent the band-wrapping tape T wound around the banknote bundle N from being loosened after cutting ( (Indicated by reference numeral 12 in FIG. 4)
It becomes difficult to provide separately. Therefore, in this embodiment, a heater / cutter mechanism 26 having the following structure, which also has a tape pressing function, is provided.

The heater / cutter mechanism 26 is provided near the outer periphery of the rotary gear 20 and integrally has a tape pressing function, a tape heat sealing function and a tape cutting function. That is, the operating lever 2
8 is rotatably connected to, for example, a frame of the apparatus via a shaft 32, and when the cam 31 acts on the cam follower 30, the tip of the shaft 8 is centered on the shaft 32 with respect to the crank support 22. It is rotatable in the approaching direction (J direction) and the moving away direction (K direction).

Further, the tip end portion of the actuating lever 28 and the central portion of the substantially L-shaped connecting arm 34 are connected via the swing connecting shaft 33. A heater block arm 37 is pivotally supported by the swing connecting shaft 33, and a heater block 36 is fixed to the tip of the heater block arm 37. Thus, via the swing connecting shaft 33,
The operating lever 28, the connecting arm 34, and the heater block arm 37 are swingably connected to each other.
The heater block 36 has, for example, a substantially semicircular tip portion.

The auxiliary lever 38 has, at one end thereof,
For example, it is rotatably supported by the frame of the device via a shaft 39, and at the other end thereof, the connecting arm 3
4 is fixedly connected to a portion of the rocking connecting shaft 33 on the tip side of the swing connecting shaft 33. Further, a cutter 42 for cutting the band-sealing tape T is attached to the tip end side portion of the connecting arm 34 via an adjusting bolt 40. The tip of the cutter 42 (the portion including the cutting blade) is inclined toward the heater block 36. The auxiliary lever 38 is the connecting arm 34 to which the cutter 42 is attached as described above.
Since the cutter 42 is fixedly connected with the cutter 42, it is possible to cut the band-sealing tape T at a constant operation angle without rattling.

The adjusting bolt 40 is used for the heater block 3
6 is screwed to the heater block arm 37 so as to be movable back and forth at a right angle to the heater block arm 6. The adjustment bolt 40 may be tightened (that is, with respect to the heater block 36) depending on the forward / backward movable condition and the condition that the tip of the cutter 42 is inclined with respect to the tip of the heater block 36 as described above. By moving it forward or loosening it (retracting it with respect to the heater block 36), the cutting blade of the cutter 42 with respect to the band-sealing tape T and the heater block 3 are removed.
It is possible to adjust the working position relationship with 6. According to this embodiment, as will be described later, as the actuating lever 28 rotates in the J direction, the heater block 36 first presses the banding tape T against the clamp support 22, and the pressing Heat the banding tape T a little while keeping it closed. Thereafter, the heating seal portion 36b completely heat seals the band-sealing tape T (more precisely, when the necessary heat-sealing is almost completed), and the cutting blade of the cutter 42 cuts the band-sealing tape T. ing. By such adjustment of the action position relationship, the heater block 36 and the cutter 42 can rotate the actuating lever 28 in the J direction to a predetermined action position where the heater block 36 and the cutter 42 come into contact with the bandage tape T and act. The pressing, heat sealing and cutting can be performed integrally at the above timing.

Further, in the heater block 36, the swing connecting shaft 33 is provided by a spring 41 provided between the tip of the block 36 and one end of the connecting arm 34.
Is always urged in the clockwise direction in FIG. Due to this biasing force, the heater block 36 is
As will be described later, is elastically in contact with the band-sealing tape T and can be pressed elastically.

Furthermore, according to the bill banding device of this embodiment, the control unit 44, which is, for example, a microcomputer, rotates in the rotation direction of the reversible reel driving motor M connected to the reel 24 (that is, the above-mentioned direction). Reel 24
The positive direction for sending the band-sealing tape T from the reel, and the negative direction for rewinding the band-sealing tape T on the reel 24),
Also, by controlling the rotation amount thereof as shown in FIG. 2, the tightness of the band-sealing tape T can be variably adjusted over a wide range as desired. That is, in this case, the desired tightness is controlled by appropriately changing the ON / OFF time ratio (duty ratio) of the drive pulse in the negative direction or the positive direction with respect to the motor M, that is, the banding tape T of the motor M is sent out. It is realized by controlling the torque for rewinding and rewinding. That is, for example, the greater the duty ratio of the drive pulse in the negative direction with respect to the motor M, the greater the degree of tightness.

With this structure, unlike the conventional device in which the tightness of the band-sealing tape T can only be uniformly adjusted by the spring within a limited range, the present embodiment is different. There is an advantage that one bill banding device can variably and variably adjust the tightness of the banding tape T and can universally meet the demands of various users.

Next, with reference to FIG. 2 and FIG. 3, one characteristic operation example of the bill banding device according to this embodiment will be described. As described above, the banknote bundle N is clamped, and the rotary gear 20 is rotated in a state where the leading end of the band-sealing tape T is sandwiched between the banknote bundle N and the slide clamper 23. Banding tape T
When the winding amount of is a predetermined amount (in FIG. 3, the banding tape T is wound around the bill bundle N by a predetermined amount), first, the heater block 36 is operated so as to approach the crank support 22. The lever 28 starts rotating in the J direction toward the operating position. At the same time, the motor M turns to A in FIG.
2 is continuously driven in the negative direction for a certain period of time, and then is further intermittently driven in the negative direction as shown in B of FIG. As a result, the extra looseness of the band-sealing tape T wound around the banknote bundle N is eliminated. That is, the negative duty ratio of the motor M at this stage is set to be adjustable by the user according to the desired tightness.

The tip of the heater block 36 is
As shown in FIG. 3A, when the band-wrapping tape T wound around the banknote bundle N by a predetermined amount is elastically pressed, C in FIG.
As shown in, the intermittent driving of the motor M in the negative direction is stopped, and thereafter, the heater block 36 starts the heat sealing of the band-sealing tape T. Then, as shown in D of FIG. 2, the motor M is driven in the forward direction for a relatively long time, and the banding tape T is loosened between the heater block 36 and the reel 24. By this slack,
It is possible to prevent the banding tape T from being broken due to the pressing force of the heater block 36. Then, as the operating lever 28 further rotates in the J direction, the heater block 36 and the cutter 42 advance toward the central portion of the banknote bundle N, as shown in FIG. 3B.

Next, as shown in FIG. 2D, the motor M is driven in the negative direction again, so that the band-sealing tape T is pulled. By utilizing this pulling force (tension), the band-sealing tape T is cut. It will be cut by 42. When the cutting of the band-sealing tape T is completed, the operation lever 28 is rotated and returned in the K direction to the non-acting position where the heater block 36 and the cutter 42 are separated from the band-sealing tape T, and the slide clamper 23 is returned to the initial standby position. By retracting, the bundle of banknotes N that has been banded is discharged to a predetermined stacker (not shown).

The means for rotating the banknote bundle N is not limited to the rotary gear 20 as described above, but may be any other appropriate rotating body rotated by an appropriate driving means. Further, the present invention is not limited to the banknote banding device as in the above-described embodiment, but may be implemented as another paper band banding device for banding a bundle of paper sheets other than banknotes.

[0030]

As described above, according to the present invention, the clamped sheet bundle is rotated with respect to the sheet bundle tape to wind the sheet bundle tape around the sheet bundle bundle. Further, a heater block for pressing the band-sealing tape to heat-seal it and a cutter for cutting the band-sealing tape heat-sealed by the heater block at a predetermined position are integrally attached to a rotatable actuating lever. The function of pressing the band-sealing tape, the function of heat-sealing and the function of cutting are integrally performed by rotating the actuating lever. As a result, the present invention has an excellent effect that the structure of the device can be downsized and simplified. Further, the present invention includes a motor connected to the reel means that supports the band-sealing tape, and the tightness of the band-sealing tape can be variously changed only by controlling the rotation direction and the rotation amount of the motor. Therefore, there is an effect that it is possible to universally realize a desired banding tightness that differs depending on the user.
