[Technical background of the invention and problems with the background art] Conventionally, in order to bundle paper sheets of a predetermined shape such as banknotes, securities, and other various cards, a tapered guide member is used between the leaves of the paper sheets. Then, insert the binding tape between the sheets spread by this guide member.The tip of the binding tape is inserted between the sheets to hold it, and then the guide member is pulled out. Rotate the holding plate that holds the paper sheets after wrapping and apply binding tape around the paper sheets.
There is a known paper sheet binding machine that wraps paper sheets around the paper sheet and binds the paper sheets by gluing the ends of the paper sheets.

In this paper sheet binding machine, the binding tape is placed around the paper sheets in a tensed state. During the tape winding, the braking device is used to feed the tape at the end of the tape winding process.

This conventional control device Ill + device II kl: consists of a cylindrical guide roller and a brake roller that can freely touch the guide roller, and when feeding the tape, the brake roller is bent from the guide roller, and the guide roller is The tape rotates freely with the tape feed f, while the brake roller is pressed by the guide roller during braking, and the tape feed f? Braking force is applied with ll-.

However, this uncontrolled UL+ device has a problem in that the braking force changes depending on temperature, humidity, etc., and uniform banding cannot be maintained. It also works to reduce brake roller wear.
There was also the problem that the braking force against the tape varied.

Furthermore, due to variations in the material of the f roller and processing accuracy, the control I force was 11!4 It was difficult to easily adjust the braking force (L+4).

The tape is wound 17 around the bundle of paper sheets (4) (ii) Braking is applied to the feeding of the tape.

The cutter 9 is driven by a cutter drive device 10, and after the tape is wound around the bundle of paper sheets in the tape winding section A, the tape is cut by a length of 4-6 degrees. After the tape is fully wound around the bundle of paper sheets and adhered, the solenoid (f, j) that is not installed is driven, and after the tape is fully wound and adhered, the tape is stamped with a predetermined seal 6 () Between the tape feeding section C and the tape winding section A. A backing plate 12 is provided. This patch plate 12c, transfer member 1
A bundle of paper sheets sent by 1vc comes into contact as shown in FIG. 1-f. The backing plate 12 is provided with an opening door for a stamping device front 13, a tape T, a bill splitting device 3, and an adhesive device 111 to be moved in and out of the tape winding position.

FIG. 2 shows the control system of the binding machine of FIG. 1.

In the same system, reference numeral 101 is a control unit comprised of a microcomputer, which controls the tying machine according to a predetermined program.

102 is pulse motor M+? In the first drive unit that rotates, the rotation pulse P, (pulse;/−
) and rotation direction signals M, -R.

M, -L (which specifies the rotational direction) and drives the pulse motor M1 according to the rotational direction signals M, -H that drive the pulse motor M, ? After normal rotation, the feed roller 4 rotates counterclockwise in FIG. 1.

103 is the drive power source of the pulse motor M1 between DC motor V and DC
This is a switching section that switches between 2 and 6 V (variable) in accordance with a switching signal CH from the control section 101. That is, when the tape is fed out by the feeding roller 4, fA is D.

give. At the same time, the supply 1r14 of the rotation pulse P1 is stopped. The reason why braking force can be applied to lowering the drive voltage and stopping the supply of rotational pulses will be described later. In addition, the DC 2-6V power supply is a variable resistor vR.
Although it is adjusted by vc, c, the variable range of voltage is not limited to 2 to 6v, and the driving voltage-torque characteristic of the pulse motor (an example of this is shown in Fig. 5f) K
, t: If set to an appropriate value, it will be possible to rotate the holding plate 2-1, 2-2.
It is driven by a second drive unit 104 that receives rotation direction signals M, -R, M, and -I. DC 24V is always applied to the pulse motor M2 as a drive voltage. Rotation direction signal M, -RK Therefore, ) (When the Luz motor M2 is rotated in the normal direction, the time keeping plate 2-1.2-2 is rotated counterclockwise in FIG. 1.

The resistors R1 to R4 are inserted to provide a constant current property to the current source and to speed up the rise of the current '1 flowing through the coil.

The cutter drive section 81) operates a solenoid in the cutter drive device 1() (FIG. 1) in response to a drive signal S from the control section 101, thereby rotating the cutter 9 as shown by the broken line in FIG. The adhesive drive unit SD, which is moved, uses a drive signal (7) S from the control unit 101 to actuate a solenoid or the like to project the adhesive device 11 and bring it into contact with the tape on the holding plate 2-1.

This bonding device 11 has a built-in heater, and the contact surface is maintained at a predetermined level at one time. On the other hand, the tape box is coated with heat-sensitive adhesive, so it cannot be heated by a heater.
The parts glued together.

The stamp drive unit SD receives a drive signal Ss from the control unit 101.
[J: Operate a solenoid or the like to slide the stamping device [113] in a direction perpendicular to the tape on the holding plate 2-1 and bring it into contact.

The bill splitting drive unit SD causes the bill splitting device 3 to act on a solenoid or the like. The bill splitting device 3 is normally operated by a spring (not shown).
As shown in the figure, the tape winding position DK protrudes, but when the bill splitter drive unit SD operates a solenoid or the like based on the drive signal from the control unit 101, the tape winding position DK is moved left and right as shown in FIG. That is, the bill splitting device 3 is pulled out from the state where it is inserted into the paper sheet and released.

105 detects the operation of each mechanism of the binding machine with a part of the sensor,
A control unit 101vc provides a detection signal. Control (8) The control unit 101 checks the operation of each mechanism based on the detection signal, and determines the content and timing of the drive signal and the like.

Next, the reason why a braking force can be applied to the tape by completely lowering the driving voltage of the pulse motor M1 and stopping the supply of the rotation pulse P will be explained.

The tape is sent to the feed roller 4 and to the c-reave winding section A.
4V and supplying four-phase rotation pulses in the forward rotation direction to the pulse motor M from the first drive unit 102.
Pulse motor M,'f rotates forward. At this time, the rotational torque for feeding the tape becomes α as shown in Figure 5'f,
The nogle motor M1 does not apply braking force to the tape j7. According to the switching unit 103, 'a' is switched and the driving voltage is set between 2 and 6.
When the torque is decreased to 0 Therefore, when one end of the tape is sandwiched between a bundle of paper sheets as described later and the bundle of paper sheets is held and rotated by the holding plate 2-1, 2-2, when the tape is pulled, β
The delivery roller, which is stopped by the torque , rotates due to the tensile force. This causes a braking force due to the torque .beta. to be applied. As a result, the tape is wound around the paper sheet while maintaining tension.

FIG. 3 shows the timing of the operation of each member of the binding machine shown in FIG. 1, and FIG. 4 shows the winding operation of the tape winding section A.

A predetermined number of sheets, for example, 100, is counted by a counting device (not shown), and a bundle of paper sheets is placed on the transfer member 1, linearly transferred to the left in FIG. 1, and hits the back plate 12 (third
Cause, time t. ) At this time, the bill splitting device 3 protrudes to the tape winding position (the state shown in Figure 1), so the paper sheets are separated as shown in the figure [2 l'r, ,! Control unit 101 receives rotation direction signals M, -R and rotation pulse P.
, and the first drive unit 102 supplies four-phase pulses to the pulse motor M in phase order in the forward rotation direction.

On the other hand, the switching unit 103 receives the signal CH and supplies DC 24V to the pulse motor M. Therefore, the Norms motor M rotates in the normal direction 17, and the feed roller 4 is driven by the Norms motor M1 to rotate in the normal direction. (Counter-chronological direction in Figure 1).

Therefore, the tape is sent to the feed roller 4, and the leading end of the tape is inserted between the bundles of paper sheets split by the bill splitting device 3. After once stopping the motor M1, the control unit 101 generates a drive signal S4?, and in response to this, moves the bill splitting drive unit SD and the U bill splitting device i13 to the left in FIG. Separation from leaf bundle - r - (t,) o order 1
1M holding plate 2-1.2-2 Crab paper chestnuts move towards the east,
Holds a bundle of paper sheets (t2).

The transfer member 1 and the holding plates 2-1, 2-2 are provided so as to be in contact with the paper sheets at different positions in the longitudinal direction of the paper sheets (direction perpendicular to the plane of the paper in FIG. 1). Therefore, the holding plate 2-1. ．． Even if 2-2 moves to a position where it can hold the paper sheet, it does not hit the transfer member IK.

After the holding plates 2-1 and 2-2 hold the paper sheets, the transfer member 1
moves to the right from the tape winding position.

As a result, the state shown in FIG. 4(a) Vc is obtained.

(11) Next, pulse motor M1 starts normal rotation again (t3) After a little delay f, pulse motor M2 starts normal rotation (t4
). In order to rotate the pulse motor Mxk in the normal direction, the control unit 10
1 generates a rotation pulse P2 and a rotation direction signal M2-R,
The second drive unit 104 receives these and supplies them to the four-phase motor M2 in the forward rotation phase order.As a result, the holding plate 2-1. (b
) to (d) The pulse motor MIIl- rotates as shown in Fig. 4(b) and stops (t,) ot, after which the supply of the rotating motor (P, The driving voltage is switched to DC2 to DC6, and the application of braking force to the tape by the pulse motor M1 is started. ) In this way, even if the braking force is applied, if the state shown in Fig. 4(b) is reached,
Since the tape whose tip end is inserted into the bundle of paper sheets is bent at a substantially right angle, it will not come off from the bundle of paper sheets. Therefore, the tape can be tightly wrapped around a bundle of paper sheets in a taut state. Control (12) The power is applied using the retaining plate 2-1.2-2 described below.
□Pulse mode 5 lock, forward rotation of l is the 4th +
Continues until g+ (d) -hru(t,).

Figure 4 shows the case where the tape is wrapped once, μ,
It is also possible to wrap the tape more than once. In this case, the time from t5 to tll trench in FIG. 3 becomes longer.

After the pulse motor stops, the control unit 101 outputs the drive signal 81.
The cutter drive unit 8D outputs the cutter drive unit 8D, and the cutter drive unit 1
0, the cutter 9 rotates and cuts the tape as shown in FIG. 4(d)K (t7). At the same time, the pulse motor M is switched from an operating state in which braking chips occur to an operating state in which the tape is pulled in the opposite direction. That is, the control section 10
1 generates rotation pulse P1 and reversal signals M, -L,
In response, the first drive unit 102 supplies pulses in phase sequence in the reverse direction.

Moreover, the switching unit 103 is set to 24V DC? select. This,
When Vc is applied, the pulse motor M tries to rotate the feed roller 4 clockwise, which increases the tension on the tape and makes cutting the tape more reliable. After a delay, the control unit 101
outputs a drive signal S2'fr, and the adhesive drive unit SD.

The adhesive section 11 moves to the position shown in FIG. 4(e) Vc, and the tape is thermally bonded by the internal heater (t,). Next, as shown in FIG. 4(f) Vc, the stamping device 13 operates and stamps the tape for confirmation f(t).
,).

After turning t, the pulse motor is rotated in the reverse direction (too), and the retaining plate 2-1.2-2 is rotated clockwise, and as shown in FIG.
) and stops at a fixed point in time (1,,). Thereafter, a paper sheet presentation device (not shown) transfers the bound bundle of paper sheets from the holding member 2-1.2-2 to the outside -f(tu).

Accordingly, the holding plates 2-1, 2-2 return to the position shown in FIG. And the bill splitting device 3 is at the tape winding position DK.
It protrudes and prepares for the transfer of the next bundle of paper sheets (1.,).

In the above embodiment, in order to apply braking force to the tape, the drive voltage of the pulse motor M is reduced, but it is also possible to change the pulse rate instead.
In other words, the pulse motor has a relationship between the pulse rate and the torque. Sometimes the pulse is in the reverse direction [600PPSσ)? give. Then, an opposite torque of +7-m is generated at 5, which provides a braking effect. Furthermore, a pulse rate selection means (for example, a selector switch is provided with [repulse rate l-
) and set up a system for its output.
01 and the pulse rate can be set according to the specified f value.However, the present invention is not limited to the binding machine having the structure shown in FIG. It can also be applied to a structure in which r+' a <, for example, the paper sheet is held stationary and the tape is rotated around the paper sheet A and wound around the tape. Furthermore, the period between +CII and the braking force applied to the tape can also be changed as appropriate depending on the structure of the binding machine. Note that Figures 5 and 6 only show examples of torque characteristics, and these characteristics may vary depending on the pulse motor used.
Driving for providing braking force of 4i (15) The values of voltage and pulse rate should be appropriately selected according to the characteristics of the pulse motor.

〔Effect of the invention〕

As described above, the present invention enables uniform banding without being affected by variations in temperature, humidity, material, processing accuracy, etc., and without wear of the delivery roller. - Furthermore, by adjusting the drive voltage or pulse rate of the pulse motor, it is possible to adjust the braking force precisely and delicately.
