Description

[Detailed description of the invention] The present invention relates to a start control device for a paper sheet binding machine that automatically binds a predetermined number of paper sheets, and in particular, the invention relates to a start control device for a paper sheet binding machine that automatically binds a predetermined number of sheets. The present invention relates to a start control device for a binding machine that binds paper sheets.

Generally, paper sheets, such as banknotes, are tied together with tape after a predetermined number of sheets have been calculated, so that they can be easily handled later as a bundle of bills of a predetermined amount.

In such paper sheet binding machines, if the binding tape is thermally bonded using a heater or the like, the binding operation must be performed after the heater or the like has been sufficiently heated.

This is because even if the binding operation is performed in a state where the heater or the like is not heated, the binding tape will not be thermally bonded and the paper sheets will not be bound.

Therefore, it is desired to develop a sheet binding machine that performs binding operation after the heater etc. are sufficiently heated to be in a state where the tape can be thermally bonded.

In addition, conventional machines have the inconvenience of starting the machine even when no tape is loaded or the tape is not securely set in a position where it can be fed, and manual machines also have the disadvantage that paper sheets are inserted into the binding section. There was also the inconvenience that the machine would start manually even if it was not inserted properly or if it was not inserted properly, so there was a desire for an improved machine.

Therefore, the present invention is designed to satisfy such requirements.

Examples of the present invention will be described below.

First, a mechanical outline of the paper sheet binding machine of the present invention is shown in FIG.

In the figure, 1 is paper sheets installed in a binding section 2 to be bound, and 3 is a paper sheet 1 inserted into the binding section through a receiving opening 5 provided in a machine frame 4, which is held between both sides. A pair of pressure holding plates for holding, 6 a tape reel wound with a binding tape 7 and loaded into a tape reel support part 8; 9 a tape reel 9 that holds the binding tape 7 pulled out from the tape reel 6 to the binding part 2; A tape feeding unit 10 is a tape feeding unit 10 that applies a binding tape 7 to the side edge of the paper sheet 1 held by the pressure holding plate 3, which corresponds to the regulation surface 11 side.
12 is an operation key consisting of a power switch etc. which is operated from the outside.

Although not shown in the figure, there is also a tape bonding device that wraps the binding tape 7 around the paper sheets 1 and then heats the tape to perform temporary and final binding, and a tape cutting device that cuts the tape after binding the tape. and a drive system for each of the above devices.

The paper sheet binding machine having such a general configuration performs the following operations.

First, the tape reel 6 is loaded and the binding tape 7 is loaded up to the tape insertion plate 10.

Next, use the operation keys to make power supply and other preparations.

When a predetermined number of paper sheets 1 to be bundled are placed on the regulating surface 11 and installed in the binding section 2, they are held between the pressing and holding plates 3 and the binding section 2 is rotated together with the pressing and holding plates 3 by the drive system.

Then, once the rotation is stopped, the binding tape 7 is inserted into the side edge of the paper sheet 1 using the tape insertion plate 10, and then rotated again and subjected to temporary heat bonding (temporarily stopped) to the required length. Cut the end of the tape.

Then, main heat bonding is performed, the paper is rotated to the initial position (or the opposite position to the initial position) and then stopped, and the bundled paper sheets are pulled out.

When the paper sheet is removed, the pressure holding plate 3 opens to the initial position,
Since the regulating surface 11 of the reception opening 5 is on the same lower side (or upper side) as the first one, if another paper sheet to be bundled is inserted and placed next time, the same binding operation will be performed.

Next, a control system for performing such a bundling operation is shown in FIG. 2 in correspondence with FIG. 1.

This is a contact point of a limit switch LM2 that turns on and off in response to 37 (described later).

Here, the binding tape 7 is set on the tape insertion plate 10, for example, as shown in FIG.

That is, in FIG. 3, the binding tape 7 stored in the tape reel 6 is pressed against the engagement roller 31 and
roller 33 that engages with tape 2 and transports the tape to tape feeding section 9;
are sequentially sent to the binding section via the .

The pressing engagement roller 31 is supported by a rotating shaft 35 provided on the operating piece 34, and is always rotated counterclockwise by a spring 36.

Therefore, the end of the actuating piece 34 has a limit switch LM.
3 are provided in engagement with each other.

Therefore, when the binding tape 7 is set, its detection contact piece is pressed.

In this way, the setting of the binding tape 7 can be detected by the limit switch LM3, and the operating contact of this limit switch LM3 is used as the changeover switch 21.

Further, the rotational drive of the motor M is transmitted through a transmission control device 29,
The signal is transmitted to a drum mechanism as shown in FIG.

That is, in FIG. 4, 5 is the above-mentioned receiving port for inserting paper sheets for bundling, 37 is a rotary cam having a groove 38 connected to the drum 2A, and LM2 is a rotary cam for detecting the position of the groove 38. A limit switch 39 is provided corresponding to the rotating cam 37. A connecting cam 39 rotates at a constant ratio with the rotating cam 37 and has a groove 40. A connecting cam 41 is provided at the end with a spring 43 around a fulcrum 42. The SOD is a retaining piece for pressing the rotary roll 44 onto the rotating peripheral surface of the connecting cam 39, and the SOD is the aforementioned retaining piece for attracting the retaining piece 41 and causing the rotary roll 44 to escape from the groove 40 when excited. The solenoid LM1 is the aforementioned limit switch provided corresponding to the retaining piece 41 in order to detect that the rotating roll 44 has fallen into the groove 40.

The operation of the paper sheet binding machine having the general configuration as described above will be explained with reference to the time chart of FIG. 5 and the state diagrams of FIGS. 6 to 10.

First, the case of the automatic start mode in which the mode changeover switch 23 is connected to the contacts A and A2 will be described.

Now, if the power switch 20A is turned on at time t1, the indicator lamp 45 lights up and the heater 25 is heated through the interlocking contact 20B.

The heating temperature of the heater 25 corresponds to the temperature of the hollow resistor 27, and this temperature is detected by the thermistor 26.

That is, since the resistance value of the thermistor 26 decreases as the temperature rises, the transistor Q1 of the relay amplifier 28 is finally switched from on to off, and the transistor Q1 is finally switched from on to off.
3 is switched from off to on (time t2).

Therefore, at time t2, relay RYA is energized, its contacts RYA1 and RYA2 are turned on, and appropriate temperature display lamp 46 is lit.

This indicates that the heater 25 has been sufficiently heated to a state where the binding tape 7 can be thermally bonded.

On the other hand, if the binding tape 7 is set, the no-tape alarm lamp 22 will be off, so that it is checked whether the binding tape 7 is set at a predetermined position.

If the no-tape alarm lamp 22 is lit, the binding tape 7 is set.

Therefore, the paper sheets 1 to be bundled are placed at the receiving port 5 of the drum 2A.
and installed at the bundling position inside the receiving port 5,
This is detected by a paper sheet insertion detector (not shown) that is detected by a limit switch, etc., and contact OAK is turned on (Fig. 5, 0).
AK).

Note that when inserting the paper sheets 1 to be bundled into the receiving port 5, the operation detection switch OTS (described later) is turned on, and the relay contact RYB1 is also turned on because the relay RYB has returned to its original state. It has become.

Thus, when contact OAK turns on at time t3, relay RYC is energized (FIG. 5 0AK), relay contact RYC1 turns on and remoter M is driven (FIG. 5 M
).

When the motor M is driven, a reduction gear mechanism 30 is attached to its rotating shaft.
The timing cam TKI connected through the motor rotates, turns on the timing cam switch ATK1, and thereafter self-maintains the rotation of the motor M (FIG. 5, 0AK1).

In this way, when the rotation of the motor M is self-maintained and the motor M continues to rotate, the timing cam TK2 turns on the timing switch ATK2 at time t4 (0AK2 in FIG. 5).
2 is turned on, the solenoid SOD is energized (FIG. 5, 5OD), and the retaining piece 41 in FIG. 4 is attracted.

As a result, the rotary roll 44 that had fallen into the groove 40 of the connecting cam 39 escapes from the groove 40, the contact ALM1 of the limit switch LMI is turned on, and the relay RYB is energized (ALMI in FIG. 5).

On the other hand, at time t5 before and after the solenoid SOD is energized, another timing cam (not shown) connected to the rotating shaft of the motor M turns off the operation detection switch OTS, thereby cutting off the energization of the relay RYC. (0AK and RYC in Figure 5).

On the other hand, when relay RYB is energized, relay contact RYB1
is turned off, and the contact RYB2 is switched from the a3 side to the b3 side (RYB2 in FIG. 5), and the excitation of the brake BR is cut off (BR in FIG. 5).

However, due to the operation of timing cam TK3, time t6
The contact point of the timing cam switch ATK3 is switched from the a2 side to the b2 side (0AK3 in Fig. 5), and the clutch CL
is excited and the drum 2A starts rotating (Fig. 5, 2A)
.

This situation is shown in FIG. In the figure, reference numeral 3 denotes the pressing holding plate for holding the paper sheets 1 to be bundled from both sides.

In this way, the paper sheet 1 is moved together with the drum 2A at a predetermined angle, that is, from the bundling start position (from the initial reference angle position, for example, 27
0°).

Here, in the present invention, the timing cam switch ATK2 is turned off by the timing cam TK2 (at time t7).
), cut off the excitation of the solenoid SOD (Fig. 5 5OD
).

When the excitation is cut off, the engagement piece 41 shown in FIG.
3, and the rotating roll 44 is pressed onto the rotating peripheral surface of the connecting cam 39.

As the rotating roll 44 travels on the rotating peripheral surface of the connecting cam 39 in this way, the rotating roll 44 finally moves into the groove 4.
Falling into 0 (time ts), limit switch LMI
The contact ALM1 of is turned off (ALMI in FIG. 5).

Therefore, the excitation of relay RYB is cut off, and when it returns, the relay contact RYB2 changes from the b3 side to the a3 side.
Since the clutch is switched to the side, the clutch CL is disengaged and the brake B is
R is excited (CL, BR in FIG. 5).

Thus, the drum 2A stops at a predetermined position (Fig. 5, 2).
A).

When the drum 2A stops in this manner, the binding tape 7 is inserted into the side edge of the paper sheet 1 via the tape insertion plate 10, as shown in FIG.

Meanwhile, during the insertion operation of the binding tape 7, the timing cam switch ATK3 is switched from the contact b2 side to the a2 side by the timing cam TK3.

At time t9 after the predetermined operation, the timing cam TK2 turns on the timing cam switch ATK2 to excite the solenoid SOD.

Therefore, contact ALM1 of limit switch LMI is turned on and relay RYB is energized, so relay contact R
YB, , is switched from the a3 side to the b3 side.

Therefore, the excitation of the brake BR is also cut off (Fig. 5 BR
).

Thus, at time tlo, the timing cam TK3 changes the contact point of the timing cam switch ATK3 from the a2 side to the b
2 side, and clutch CL is activated.

Therefore, the drum 2A starts rotating again (Fig.
A).

Then, the drum 2A attaches the binding tape 7 wound around the paper sheets 1 at a predetermined angle to the heater 25 (tape bonding device).
Temporary heat bonding is carried out by the tape, and the tape is rotated to a position (for example, 765° from the initial reference angle position) where the tape is cut to a required length and then stopped.

Therefore, at time tll, the timing cam TK3 switches the contact point of the timing cam switch ATK3 from the b2 side to the a2 side.

In this case, even if the clutch CL is disengaged, the drum 2A continues to rotate due to the rotational inertia of the drum 2A and other components.

Then, the rotating roll 47 of the limit switch LM2 falls into the groove 38 of the rotating cam 37 shown in FIG.
M2 is turned on, the brake BR is applied, and the drum 2A is stopped (FIG. 5, 2A).

In addition, the drum 2A rotates with inertia and the brake BR
The time it takes to stop is short.

When the drum 2A stops rotating, as shown in FIG. 8, the binding tape 7 wound around the paper sheets 1 is preheated by the heater 25 and cut into bundles by the tape cutter 48 (tape cutting device). Cut the tape 7 to the required length.

When such a predetermined operation is completed, at time t13, the contact point of the timing cam switch ATK3 is switched from the a2 side to the b2 side by the timing cam TK3, the brake BR is disconnected, the clutch CL is engaged, and the drum 2A starts rotating ( Figure 5 2A).

Immediately after the drum 2A starts rotating, the rotating roll 47 of the limit switch LM2 escapes from the groove 38, so its contact ALM2 is turned off (ALM2 in FIG. 5).

In order to finally heat-bond the temporarily heat-bonded binding tape 7A (the tape wound around the paper sheet 1), the contact of the timing cam switch ATK3 is moved to the a2 side in the same manner as in the case of the temporary heat-bond described above. to the b2 side (time t14), and the drum 2A is stopped via the limit switch LM2 (time t1). After the rotation of the drum 2A is stopped, the binding tape 7A is permanently bonded as shown in FIG.

The binding tape 7 used in this invention has a heat-soluble adhesive such as vinyl resin applied to one side of the tape, so the binding tape 7 is heated by the heater 25.
A is welded and the tape is finally fixed.

In this way, when the main heat bonding process is completed, the drum 2A starts rotating in the same way as in the case of the temporary heat bonding described above (at time t16).
).

When the binding tape 2A is fully thermally bonded and permanently fastened in this manner, the drum 2A is rotated to the first reference angular position (or the opposite position) and stopped at that position in preparation for the next binding operation.

Therefore, at time t17, timing cam TK2
The timing cam switch ATK2 is turned off to cut off the excitation of the solenoid SOD.

When the excitation is cut off, the rotating roll 44 is pressed onto the rotating peripheral surface of the connecting cam 39, and finally the rotating roll 44 moves into the groove 40.
Falling into the middle of the day (at time t).

Therefore, the excitation of relay RYB is cut off and restored,
Relay contact RYB2 is switched from the b3 side to the a3 side.

Therefore, the clutch CL is disengaged, the brake BR is applied, and the drum 2A is stopped at the position shown in FIG. 10.

In this example, it is 900° with respect to the initial reference angular position.

At time t19 after the drum has stopped, the timing cam T
K1 turns off the timing cam switch ATK1, releases the self-holding state of the motor M, and stops driving the motor M (ATK1.M in FIG. 5).

Here, when the bundled paper sheets 1 are pulled out from the receiving port 5 of the drum 2A, the contact OAK of the paper sheet insertion detector (not shown)
is turned off at time t20, and when it is further pulled out, it is detected by the paper sheet extraction detection device (not shown) via the pressure holding plate 3, and the operation detection switch OTS is turned on (
Time t2□).

Therefore, when another paper sheet to be bundled is inserted next, the contact OAK of the paper sheet insertion detector (not shown) is turned on and the same bundling operation as described above is performed.

In this case, unless the operation detection switch OTS is turned off, the relay RYC will not be excited and the motor M will not be driven, no matter how many times the contact OAK is turned on.

In other words, the bundling operation does not start until the paper sheets are completely removed from the receiving port (or drum).

Therefore, paper sheets that have been bound once are not bound again and again, and there is no possibility that the drum starts rotating during the picking operation.

Furthermore, since it is thermally bonded onto the pressure holding plate, there is no chance of damaging the paper sheets.

The above explanation is about an example of the operation in the automatic start mode, but in order to tie in the manual start mode, the mode selector switch 23 is turned to the M, M2 side.

Therefore, in the manual start mode, the indicator lamp 24 is turned off, and the motor M is not driven even if sheets to be bundled are inserted and the contact OAK of the sheet insertion detector is turned on.

The motor M is driven when the start button 49 is pressed after paper sheets are inserted.

Thus, once the motor M is driven, it performs the same operation as in the automatic start mode described above.

In this case, the only difference is the start point, and the rest is exactly the same as in the automatic start mode.

As described above, according to the start control device of the present invention, after the power is turned on, the adhesive device (heater) is sufficiently heated to be able to thermally bond the binding tape, and the presence of the tape is detected and the paper is placed at the binding position. The binding operation cannot be started unless the position of leaves is detected.

The same applies to both automatic start mode and manual start mode.

Therefore, there is no possibility of a bundling mistake, and the bundling operation can be started safely and reliably.

Furthermore, the temperature of the heater is detected by the temperature of a hollow resistor connected in series with the heater.

The heater is movable due to thermal adhesive tape,
Since the hollow resistor can be fixed at another position, it has the advantage of high safety and reliability for detecting the temperature of the heater.

In the above embodiments, the temperature of the bonding device (heater) is detected by a thermistor, but it is also possible to use other temperature-sensitive elements (for example, barrettes, posistars).

Furthermore, in the above embodiments, the paper sheet itself was rotated and the tape was wound around it, but the invention is not limited to this. It goes without saying that the present invention can also be applied to similar binding machines.
