The technique disclosed in Japanese Patent No. 55-44727 can be mentioned.

The drive system in this device consists of a dividing device that divides the paper stack, a clamp device that clamps the paper stack, a tape winding device that wraps the tape around the paper stack, and a tape winding device that wraps the tape around the paper stack to prevent the tape from loosening after wrapping. It comprises a tape handling device for holding, a tape sealing device for thermocompressing the ends of the cut tape, and a drive device, and each of these devices constitutes a dividing device, a clamping device, a tape handling device, and a tape sealing device. Each operating member is coupled to a cam plate having a corresponding camward surface, and each cam plate is fixedly arranged on the same rotating shaft member.

are connected to each other through the 2-axis and are configured to be rotated at the same time. Further, a cutter that cuts the tape when the paper bundle is wound a predetermined number of times is connected to the solenoid.

c Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, in order to control the required rotation and stop of the operating members of each device constituting the drive system in the banding part, the main operations are mechanically operated. Each cam was controlled in a predetermined time sequence by relying on the cam disc of the The cam surface of the plate was complicated, and the mechanical structure was also extremely complicated.

Therefore, if the work is interrupted by turning off the power for some reason during the bundling operation, even if the power is turned on next time, only one main motor will operate depending on the stopped position of the operating member. Based on the fact that the overall arrangement of each member is strong enough to cope with the situation, the load becomes extremely large in order to restart from the stopped position, and the state where it seems to be fixed at that stopped position. This problem often occurs, and furthermore, it requires a great deal of effort and time to return to the original position.

Furthermore, as mentioned above, since the various operating members are commonly connected to one main motor and are arranged to operate according to the sequence determined by the cam plate, all drive A drive motor with a large rotational torque that can withstand the operation of the system has become necessary, and the equipment has tended to become larger.

The present invention has been made in view of the above-mentioned problems, and the drive system of the banding section is separated into a banding ring drive system and a cam member drive system and driven separately, and an encoder section is also provided. It is an object of the present invention to provide a paper sheet binding machine that can maintain the periodic relationship of the entire drive system including both drive systems based on the detection output based on the predetermined rotation angle position of the slit plate.

d. Means for Solving the Problems The paper sheet binding machine according to the present invention includes a paper sheet clamp section for clamping the paper sheets with tape fed into the bill splitting section when setting the paper sheets. , a loop-shaped banding ring for banding paper sheets in a clamped state; a heater for thermocompression-bonding the cut ends of the tape that sealed the paper sheets; and a heater for rotating the banding ring. a main body ring drive motor; a plurality of cam plates each having a cam surface for controlling the paper sheet clamp section that performs the action of bundling the paper sheets, the heater, etc. by mechanical engagement.

e Effect In the above-mentioned configuration, when the camshaft drive motor rotates, the slit plate of the encoder section rotates, and as a result, when a detection signal corresponding to a predetermined rotational position of the slit plate is obtained, the detection signal is detected based on the detection output. The generated control signal causes the tape feed motor to start rotating, and the banding tape is guided between the sheets being separated by the separating device. Next, the control signal based on the detection output corresponding to the predetermined rotational position of the slit plate from the encoder section is used again.
When the main body ring drive motor rotates, the banding ring (flyer main body) of the banding unit rotates, and the banding tape begins to wrap around the bundle of paper sheets. When the banding is completed, the slit plate is similarly moved from the encoder unit to the specified position. The cutter solenoid is actuated by a control signal based on the detection output corresponding to the rotational position, and after the end of the banding tape is cut, the cut part of the tape is bonded by thermocompression by the actuation of the heater cam plate. The banding ends.

Next, in the case where the sheet binding machine according to the present invention is operated to perform binding in the above configuration, the relationship between the driving state of each drive unit and the output signal from each optical switch unit in FIG. 3 will be explained. This will be explained together with a timing chart showing the same, and a flow chart for explaining the operating state of each drive section in FIG.

Now, when a certain number of paper sheets 10 (for example, a bundle of banknotes) is inserted into the paper sheet insertion slot 1a of the paper sheet binding machine 1, the paper sheets 10 are divided into left and right by the dividing device 22. Further, when the paper sheet 10 is inserted to a predetermined position, the paper sheet detection section 11 detects the paper sheet 10.
By detecting the setting operation of the camshaft (step 1) and generating an on signal, the camshaft drive motor 43 rotates, the shaft drive gear 41 rotates via the drive gear 44, and at the same time the slit plate forming the same axis rotates. 32 and each cam 45, 47, 48 and 49 rotate.

As each of these operating members rotates, a pulsed output signal corresponding to the length of each slit group 31 on the slit plate 32 is obtained from the encoder section 30, and when the slit plate 32 rotates by a predetermined angle, , the output signals at that point are as follows: The detection signal of the first optical switch section 38 is "0", the detection signal of the second optical switch section 37 is "0", and the detection signal of the third optical switch section 36 is "1". ", the detection signal of the fourth optical switch section 35 is "1", the detection signal of the fifth optical switch section 34 is "1", and the detection signal of the sixth optical switch section 39 is "1", then this The output signal will match the set output [001111] in the ROM 52 for operating the tape feed motor 27 (step 2). Based on this matching output obtained,
A control signal is issued from the CPU 51, the tape feed motor 27 is started, and the cutting groove 5 of the dividing device 22 is
The tip of the tape 8 that has been inserted into the paper sheet 10 passes through the space between the guide block 15 and the guide roller 14 that are in a standby state, and is inserted into the space between the divided paper sheets 10 for a certain period of time. When _T1 has elapsed, the rotation of the tape feed motor 27 is stopped.

At the same time as this tape feed motor 27 stops, each optical switch section 3 of the encoder section 30 is activated according to the rotation angle of the slit plate 32 at this point.
An output signal of [100111] is obtained from 8, 37, 36, 35, 34 and 39, which corresponds to the set output for operating the splitter drive solenoid 23 (step 3). Based on this coincidence output being obtained, a control signal is issued, the splitting device drive solenoid 23 is activated, and the splitting device 22, which is located in the insertion path and performs bill splitting when the paper sheet 10 is set, is activated.
is retracted below outside the rotation radius of the guide roller 14 and guide block 15, with the leading end of the tape 8 still inserted into the sheet 10.

At this time, the chuck opening/closing lever 46 projects forward in advance due to the rotational action of the chuck opening/closing cam 47, and its cam surface 47a touches the guide block 15.
By engaging with the locking roller 15a of the splitting device 22, the guide block 15 and the guide roller 14 are held apart from each other without contacting each other as described above. As the opening/closing cam 47 rotates, the chuck opening/closing lever 46 moves back at a required rotation angle position and releases the engaged state. At the same time, the guide block 15 is disengaged.
is biased by the spring (not shown), so that it can move within the opening 16. Therefore, the guide block 15 and the guide roller 14 change from a separated state to a contact state, and the front part of the tape 8 is brought into contact with both sides. It is lightly held between the members.

On the other hand, as the clamp cam 45 rotates in synchronization with the chuck opening/closing cam 47, the clamp portion 2
0 operates to press the clamp plate 18 against the guide support 19 to clamp the paper sheet 10. When the operation is completed, the slit plate 3 is moved by the camshaft drive motor 43 which is continuously rotating during this time.
2 are also rotating coaxially, so each optical switch section 38, 37, 36, 35,
An output signal [011101] matching the set output for operating the main body ring drive motor 5 is obtained from 34 and 39 (step 4). When this matching output is obtained, a control signal is subsequently issued, so that the main body ring drive motor 5 starts rotating, the fryer main body 2 rotates in the direction of the arrow via the drive gear 6, and the tape 8 is guided It is held between the rollers 14 and the guide block 15 and guided as they rotate, and is unwound from a tape reel (not shown), and is wound around the paper sheet 10 a predetermined number of times, for example, 1.75 turns.

In the aforementioned rotational operation, the rotational state of the main body ring 3 in the fryer main body 2 is determined by the number of teeth detecting section 12 counting the number of teeth of the gear section 3a, and when a predetermined number of teeth is detected (step 5), Based on the detection signal, a control signal is issued for a predetermined period of time, the cutter solenoid 28 is activated, and when the number of teeth detecting section 12 counts the remaining number of teeth of the gear section 3a, the operation is stopped and the cutter solenoid 28 is activated. With the tape 8 of a predetermined length being fed out, the cutter 29 cuts the rear portion of the tape 8.

When the cutting of the tape 8 is completed, the horizontal presser lever 21 which is interlocked with the horizontal presser cam 49 at a required rotational angle position is operated to press the rear end of the tape 8 against the side surface of the bundle of paper sheets 10. When the fixed position detection unit 13, which monitors the rotational state of the movable plate 4 co-rotating with the main body ring 3, detects that the movable plate 4 has rotated twice (step 6), the detection is performed. A control signal issued based on the signal causes the main body ring drive motor 5 to stop rotating, and the fryer main body 2 to also stop rotating.

In the above-mentioned state, before the main body ring drive motor 5 stops, the heater block 9 which is interlocked with the heater cam 48 at a predetermined rotation angle position starts its downward movement, and thermocompresses the rear end of the open tape 8. Tape 8 created by this heater block 9
Before the thermocompression bonding is completed, the chuck opening/closing lever 46, which had been retracted by the rotation of the chuck opening/closing cam 47, protrudes forward again and returns to its original position, and at this time, the cam surface 47a touches the guide block. By engaging with the locking roller 15a of 15, the guide block 15 is secured to the guide roller 1.
4 to form a spaced state with a gap for the dividing device 22.

Next, when the camshaft drive motor 43 continues to rotate and the slit plate 32, which is also coaxially rotating, further rotates by a predetermined angle, each optical switch section 38, 37, 36, 3 of the encoder section 30
Output signals [001100] that match the set output for stopping the rotation of the camshaft drive motor 43 are obtained from the output signals 5, 34 and 39 (step 7).
Based on the fact that this matching output is obtained, a control signal is issued, and the camshaft drive motor 43 is temporarily stopped, and at this time, the clamp section 20 is controlled to be in a half-open state by the rotational operation of the clamp cam 45. Therefore, the paper sheet 10 that has been bound can be taken out from the clamp section 20. When the paper sheet 10 is taken out from the clamp section 20, the paper sheet detection section 11 generates an off signal indicating that there is no paper sheet (step 8), and based on this detection signal, the paper sheet detection section 11 generates an off signal indicating that no paper sheet exists. The control signal starts the camshaft drive motor 43 again.

When the slit plate 32 continues to rotate and rotates by a predetermined angle, each optical switch section 3 of the encoder section 30
8, 37, 36, 35, 34, and 39 provide output signals [010100] that match the set output for stopping the operation of the dividing device drive solenoid 23 (step 9). Based on this matching output, a control signal is issued to stop the splitter drive solenoid 23 from operating, causing the splitter drive solenoid 23 to stop operating.
is raised from the lower retracted position outside the rotation radius of the guide roller 14 and guide block 15 due to the biasing action of the spring, and the guide roller 14
and the guide block 15.
2, and is again placed in a state where it can be divided and operated with respect to the insertion path for paper sheets 10.

Next, when the dividing device 22 is set to a standby state, when the slit plate 32 is rotated by a predetermined angle, each optical switch section 3 of the encoder section 30 is
Output signals [011000] that match the set output for operating the tape feed motor 20 are obtained from the output signals 8, 37, 36, 35, 34 and 39 (step 10). Then, a control signal is issued based on this coincidence output, and the tape feed motor 27 is started again.After a certain period of time _T2 , the tape feed motor 27 is stopped, and during this time, the dividing device 22 is turned off. The tape 8 is temporarily fed into the groove 50. Further, the horizontal presser lever 21 and the clamp portion 20 are reset and returned to their original positions at a predetermined rotation angle position of the horizontal presser cam 49 and clamp cam 45.

Driven by the camshaft drive motor 43, the slit plate 32 and each cam 45, 47,
48, 49, etc. rotate once, each optical switch section 3 of the encoder section 30 rotates once.
Output signals [111111] that match the set output for stopping the operation of the camshaft drive motor 43 are obtained from the output signals 8, 37, 36, 35, 34 and 39 (step 11). Based on this matching output being obtained, a control signal is issued to stop driving the camshaft drive motor 43, completing one cycle of the banding operation, and waiting for the next banding operation to be performed subsequently. state.

In addition, in this embodiment, as the generation source of the drive control signal in each drive unit of the paper sheet binding machine,
The explanation was made using an encoder with an electrical configuration and a cam combination mechanism similar to the conventional configuration for the remaining part.
It is also extremely easy to control each driving section using an encoder having an entirely electrical configuration, without using the above-mentioned cam combination mechanism at all.

Furthermore, although the encoder section in this embodiment has been described as having a photoelectric configuration, this encoder section is rotated by a camshaft drive motor and includes a magnetic plate having a large number of magnetic sections, and the magnetic plate, although not shown. It may also be configured by a magnetic switch part adjacent to the plate and having a plurality of magnetic detection elements corresponding to each of the magnetic parts.

g. Effects of the Invention As described above, the paper sheet binding machine according to the present invention has a main mechanism in the drive system of the binding section, in particular, the operating members for tape feeding, tape cutting, bill splitting by the dividing device, etc., are connected to the control cam and mechanically. Since the cam mechanism can be operated independently by the output of the encoder without being coupled to the encoder, the cam mechanism can be simplified. Since the operation can be directly controlled by the output from the banding section, each mechanical section of the banding section can be operated reliably, and a series of operations for banding can be performed.
It can be executed accurately and smoothly throughout.

In addition, as a result of it being possible to reduce the number of control cams, the camshaft drive motor, which transmits rotational force to each control cam and also generates a timing signal that serves as a reference for rotation in the encoder section, is required. The combined load can be reduced, the motor needs to have a relatively small drive torque, and the assembly process and post-adjustment process can be simplified, and this can greatly contribute to improving control accuracy and reducing costs.
