Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic stamping device for automatically stamping paper and other objects, and more particularly, it is provided with a plurality of marking surfaces, one of which is placed at a marking position. The present invention relates to an automatic stamping device that automatically sets.

[Conventional technology]

For example, in an automatic stamping device of a copy making machine, a backup roller is opposed to a cylindrical stamp drum to which a printing rubber is attached. The object to be stamped is caught between the stamp drum and the backup roller, and printing is performed once with one rotation of the stamp drum.

[Problems to be Solved by the Invention]

However, since there is only one stamp face, it is necessary to replace the stamp face by hand when making another stamp. However, the workability is not good because the hands are stained with ink.

It is a first object of the present invention to provide an automatic stamping device having a plurality of stamp surfaces, one of which is automatically set at a stamp position, and a second object of the present invention is to accurately select and set the stamp surface.
The purpose of.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, a rotating member (512, 526) that is rotationally driven by a motor (520).
In addition, a printing cylinder (540, 541) having a plurality of printing surfaces is pivotally attached eccentrically to the center of rotation of the rotating member; latch wheel (542, 543)
Fixed to the printing cylinder; latch members to the latch wheel (548,549,55
1) is engaged to restrain the latch wheel stationary at every rotation of a predetermined angle; the stopper driving means (554, 555) selectively engages the stopper (552, 553) with the latch wheel to rotate the rotating member. , With the configuration to update the stamp face;
A detection means (546,547) for detecting a predetermined position of the printing cylinder; and a stopper driving means (554,555) if the detection means (546,547) does not detect the predetermined position of the printing cylinder (540,541) immediately after the power is turned on. A control means (50) for urging the motor (520) to rotate the printing cylinder (540, 541) and setting the printing cylinder (540, 541) at a predetermined position.

[Action]

When the control means (50) biases the stopper drive means (554, 555), the latch wheels (542, 543) are stopped and restrained by the stoppers (552, 553). Latch wheel (5
42,543) and the printing cylinder (540,541) is fixed to the motor (52
(0) is rotatably driven by a rotating member (512,526), so when the control means (50) urges the motor (520), the rotating cylinder (540,541) is stopped and the rotating member (512,526) is rotated. When the motor (520) rotates and the motor (520) stops, the latch member (548, 549, 551) statically restrains the rotating member (512, 526) with respect to the latch wheel (542, 543) at a rotational position of a predetermined angle unit. As described above, the printing surface occupying the position (printing position) most protruding outward from the rotation center of the rotating member due to the eccentricity of the printing cylinder (540, 541) is changed.

In this way, by energizing the stopper driving means (554, 555) and rotationally energizing the motor (520), the printing surface at the printing position is updated. This update is for latch members (548,549,55
Because of the existence of 1), it becomes a step of a predetermined angle unit, so by aligning the printing surface with this, each printing surface is in the form of step rotation at the printing position (the position most protruding outward from the rotation center of the rotating member). Accurately positioned.

When the apparatus power is turned on, the printing cylinder (540, 541) is first positioned at a predetermined position (for example, the home position) with respect to the rotating member (512, 526) by the above-mentioned stamp surface update, and the control means (50) grasps the position of the stamp surface. To do. After that, the printing surface at the imprinting position can always be specified from the rotational direction of the printing cylinder (540, 541) and the number of times of renewal feeding, so that the printing surface can be accurately selected and set.

In a preferred embodiment of the present invention, the motor (520) is a pulse motor, the rotary encoder (730) detects the feed speed of the stamp object, and the pulse motor is rotationally energized in synchronization with this speed during stamping. The rotary encoder can accurately detect the speed of the stamp object, and the pulse motor can accurately rotate and energize at a speed synchronized with this speed, so that the feed speed of the stamp object and the moving speed of the printing surface of the printing member are synchronized. The stupa image doesn't flow. Since the pulse motor can maintain a precise stop position by supplying a stop constraint current during the stop, the print member position during stop in which the printing member waits for the stamp object can be accurately determined.
As a result, the stamp position by driving the rotating member in synchronization with the arrival of the stamp object becomes accurate. In addition, the position when the rotating member is rotated once and stopped is also accurate. There is no deviation between the designated stamp position and the actual stamp position.

In a preferred embodiment of the invention, the stamping mechanism comprises at least a pulse motor (520), a first rotating member (512) rotationally driven by the pulse motor, and a second rotating member (526) coupled to the first rotating member. ), A first printing cylinder (540) pivotally attached to the first rotating member so as to be eccentric to the center of rotation of the first rotating member, and a first latch member (6) for statically latching the first printing cylinder every rotation of a predetermined angle. 548), a first latch wheel (542) fixed to the first printing cylinder, a first stopper (552) that engages with the first latch wheel when the first latch wheel is in a predetermined position,
A second printing cylinder (541) pivotally attached to a first stopper driving means (554) for driving the first stopper to an engagement position and a second rotating member (526) eccentrically with respect to a rotation center of the second rotating member. , A second latch member (549, 551) for statically latching the second printing cylinder every rotation of a predetermined angle, a second latch wheel (543) fixed to the second printing cylinder, when the second latch wheel is in a predetermined position. A second stopper (553) that engages with the second latch wheel, and a second stopper drive means (55) that drives the second stopper to the engagement position.
5), and a date stamper (556) disposed between the first printing cylinder and the second printing cylinder and coupled to at least one of the first rotating member and the second rotating member. )
Urging the first and second stoppers to the engagement position to rotate the pulse motor to rotate the first and second printing cylinders to renew the stamp surface,
After the update, the pulse motor is set to energize the stop constraint current at a level lower than the current at the time of energizing the rotation.

According to this, a plurality of printing surfaces can be arranged on each of the first printing cylinder and the second printing cylinder, and the printing surfaces can be automatically selected and set, and the date is stamped simultaneously with these printing surfaces.

Other objects and features of the present invention will become apparent from the following description of preferred embodiments with reference to the drawings.

The bearing (not shown) at the rear end of the roller 572 is tiltably engaged with the case frame of the unit 500, and the bearing 574 at the front end of the roller 572 is a vertical slit (not shown) in the case frame. Through
It is supported on the lower side by an arm 576. The arm 576 is pivotally attached to the case frame. A plunger of a solenoid 578 is connected to the arm 576 via a spring. When the solenoid 578 is energized, the arm 576 rotates clockwise, the front end of the roller 572 is lifted, and the roller 572 is pressed against the free rotating wheels 514 and 532. The printing cylinder 54
In the state where the printing surface of 0,541 and the printing surface of the date stamper 556 face the roller 572, these printing surfaces slightly project to the roller 572 side from the free rotating wheels 514 and 532. Base frame 502
A stopper 566 is attached to the. The stopper 566 is vertically movable and is urged downward by a tension spring 568. A positioning arm 570 fixed to a case frame (not shown) is located immediately below the stopper 566. The arm 570 has a large number of rectangular cutouts for receiving the lower end of the stopper 566. By pushing the stopper 566 upward and pushing the base frame to the back side, the stamp position on the paper moves to the back side in the direction orthogonal to the paper feeding direction. The stamp position moves to the front by pulling it toward you. As described above, the stamp position in the direction orthogonal to the paper feeding direction can be manually adjusted.
In addition, the adjustment of the stamp position in the paper feeding direction is based on the arrival of the leading edge of the paper as a pulse motor 520 (support plates 512 and 526).
The drive start timing is adjusted. As will be described later, this timing is set by an electric signal and is automatically performed.

The ink roller 560 is pivotally attached to the support frame 584, as shown in FIG. 5b. Sliders 586 (two) are mounted on the support frame 584 so as to be movable in the direction of arrow 593 and in the opposite direction. A compression coil spring 589 is interposed between the two sliders 586, and gives a force to pull them apart. A notch 590 for pin engagement is formed in the support frame 560, and a pin guide hole 587 and a pin guide groove 588 continuous with the pin guide hole 587 are formed in the slider 586. The ink roller unit shown in FIG.
Fig. 5b, in which the notch 590 and the pin guide hole 587 are aligned with the pins 592 and 591 that are fixed to the support arms (not shown) that are fixed to the side plates 504 and 506 of the base frame 502 with 86 close to each other. Push the support frame 584 to the right with and then both sliders 586
It is mounted on the base frame 502 by further releasing the hands and expanding the sliders 586 by the force of the spring 589. The mounted position is shown in Figure 5a. Ink roller 56
0 is removable from the base frame 502.

After the paper is detected by the sensor 598, the pulse motor 520 is biased in the forward direction at a speed synchronized with the moving speed of the paper to rotate the printing tool first and second support plates 512 and 526 counterclockwise so that the printing surface is Immediately before facing the roller 572, the solenoid 578 is energized to pull up the roller 572, and when one side of the printing surface passes the roller 572, the solenoid 578 is de-energized and the roller 572 is lowered to perform one printing. Be done. In addition, the printing surface is rolled from the standby position (home position) shown in Fig. 5a.
While moving over 572, the print surface contacts the surface of ink roller 560, compressing the surface of roller 560 slightly. As a result, the ink of the roller 560 is transferred to the print surface. An example of the stamp image is shown in FIG. 8c.

An upper cover 594 is attached to the base frame 502. Top cover 59
Fig. 5c shows the state where 4 is attached. Note that FIG. 5c shows a state in which the date changing wheel portion of the date stamper 556 is moved right below the opening 594 of the cover 594 by rotating the manual rotating wheel 522. The date can be changed in this state. In addition,
Although the date is adjusted manually like this,
A roller for changing the date is provided at a position on the base frame 502 that can face the date changing wheel of the date stamper 556 so that the roller can be moved forward and backward by a solenoid or the like, and the motor 520 is used when changing the date. Alternatively, the date stamper may be driven to set at a position facing the changing roller, and the roller may be pushed out and pressed against the date changing wheel to rotate the roller. In this way, the date can be changed automatically. Further, a drive mechanism may be coupled to the base frame 502 to automatically drive the base frame 502 in a direction orthogonal to the paper feeding direction.

7a to 7d show the control operation of the microprocessor 14 of the operation board control unit 10. The control operation of the operation board control unit 10, that is, the control operation of the microprocessor 14 will be described with reference to these drawings.

First, refer to FIG. 7a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input / output port, registers for temporary data storage, status register (flag), counter (program counter), timer (program timer), etc. Is cleared (step 1). In the following, the word "step" is omitted in parentheses and only the step symbol is displayed.

When the initialization is completed, the CPU 14 reads the status. In this, first, it is referred to whether or not there is a reading flag (2).
At this point, since the initialization has just finished, there is no read flag, so the routine proceeds to step 3, where the standard data is set in the operation board register. Standard data: Paper size: A4 Fold selection: No fold Vertical / horizontal posture: Horizontal Stamp position: 0mm Publisher: 1st design (1st publisher stamp) Drawing type: Provisional drawing (1st drawing type) Punch selection: No punch Paper output selection: Tray. When this data set is completed, the data-corresponding indicator lamp is turned on correspondingly. In this state, on the operation board 12, stand by (this is set by initialization), A
4, Indicator lights showing No Folding, Horizontal, 0mm, No Punch, 1st Design, Tray, Preliminary Drawing.

FIG. 7b shows the write position of the data to be temporarily written in the 3-byte memory area (one area of the internal RAM of the CPU 14) allocated to the operation board register OBR.

When the standard data is written in the operation board register OBR, the read flag is set (4). Next, it is determined whether or not a signal is transmitted from the copying machine 800 by referring to the state of the port that receives the input signal from the copying machine 800 (5). When the signal is transmitted, the signal and data are read in and it is determined whether the signal is a start signal (6). If it is not a start signal, it is judged whether it is an end signal (7). If it is not an end signal, it is data. Therefore, of the input data, the data whose memory bit is allocated to the operation board register OBR is stored in the operation board register. Write OBR update. When such update writing is performed, 1 is written in the bit indicated as the copier input bit of the operation board register OBR. This one
Indicates that the copying machine 800 has instructed the sheet processing machine 900 on how to perform sheet processing regarding sheet processing. Although not shown, the CPU 14 retains in memory the data received from the copying machine and indicating the data written in the operation board register OBR (indicating what the write data is). When data is received from the copying machine 800 and writing to the operation board register OBR is completed and the process proceeds to step 9, or there is no input from the copying machine 800, step 5
From step 9 to step 9, in this step the operation board 12
Read the key in. If the key-in is due to the key switches 12a-12e (10), refer to the copier input bit,
If it is not 1 (data has not yet been received from the copying machine) (11), the contents of the operation register are updated according to the key-in, and the on / off of the indicator light on the operation board is updated according to this update. For example, when the switch 12a is closed, the size specification bit of the operation board register OBR is updated to the data indicating B3 next to A4 at the moment when the switch 12a is closed, and the indicator light of A4 is turned off and the indicator light of B3 is turned on. To do. If the key switch 12a is closed once when the size specification bit of the operation board register OBR is B5, the size specification bit is set to A2.
To the data indicating that the indicator light of B5 is turned off and the indicator light of A2 is turned on. In this way, the size instruction key switch 12
Each time a is closed, the lighting of the indicator light shifts from the upper side to the lower side in Fig. 6a, and at the same time, the data of the size designation bit of the operation board register OBR changes to the data indicating the size indicated by the illuminated lamp. Will be updated. However, this operation is performed only when the size data is not received from the copying machine 800, and if the size data has already been received, the step
Then proceed to 11-12- and do not update the data or display according to the key-in. The CPU 14 also operates in the same manner for key-in by the key switches 12c to 12h.

The reason why the input data from the copying machine 800 is prioritized in this way is that the data from the copying machine 800 is more reliable than the setting by the operation board 12. When no data comes from the copying machine (for example, when the copying machine is not connected) or when only a part of the required data comes, the insufficient data is updated and set according to the key-in from the operation board 12. When no data is given from the copying machine and there is no key-in on the operation board 12, the setting data becomes the above-mentioned standard data. The start signal for starting the operation of the mechanism of the sheet processing machine is also changed by the copying machine 80, although it goes back and forth from the step development of the illustrated flow chart.
It is designed to be received from 0 and to be keyed in with the start key switch 12i of the operation board 12, but when data is partially received from the copying machine 800 (OBR copying machine input bit = 1), The key-in of the start signal due to the closing of the switch 12i is not accepted in step 38. In this way, the start signal from the copying machine is prioritized even when the processing mechanism starts.

The operation board 12 and its key-in reading / data set have meaning when the copier is not connected and when it is connected to the copier that does not transmit all required data. ) Is not connected, or if the host function is not sufficient, it is supplemented with key-in.

By setting the data in step 8 (setting the data received from the copying machine) or setting the data in step 13 (setting the key-in data), or no data is sent from the copying machine (5). If there is no key-in (9), proceed to step 14 in FIG. 7b, refer to the signal level of the signal receiving port from the unit 20,
Refer to whether it is ready (paper acceptance is possible) or not (standby: paper acceptance is not possible).

Vertical folding & 90 ° turn control unit 20 in step 14 of Fig. 7b
Is Lady, then in step 16 it is checked whether the unit 30 is Lady. When the blade folding control unit 30 is ready,
In step 18, see if unit 40 is ready.
If the punch control unit 40 is ready, then in step 20 it is determined whether the unit 50 is ready. If the stamper control unit 50 is ready, it is checked in step 22 whether the unit 60 is ready. Vertical transport & discharge control unit
If 60 is ready, all units are ready and sheet processing can be executed, so 1 is set in the ready standby bit of the operation board register OBR to indicate that processing is possible (24) and the data of the operation board register OBR is set. Pre-operation board register P
Compare with OBR data (25). Since the previous operation board register OBR has been cleared by the initialization of step 1, the contents of both do not match when the process proceeds to step 25 for the first time. This means that the processing mode data transfer to each of the units 20 to 60, which will be described later, is not executed. Therefore, first, in step 26, the data of the operation board register OBR is updated and stored in the previous operation board register POBR, and the unit 20 in the A version processing mode is shown in FIG. 7c.
Proceed to setting (27).

Setting of unit A in processing mode A in Fig. 7c (27)
Then, first, the size is judged from the data of the size designation bit of the operation board register OBR (271).

If the size is A2, then the folding selection bits of the OBR are referenced (272 to 276). If there is no fold, the unit 20 will be A2
Data indicating the transit mode is transmitted (273). When the sheet is folded in four, the data indicating the A2 / vertical folding mode is transmitted to the unit 20 (275). When folded in two, put it in unit 20, A
2. Send data indicating vertical / passing mode (277). If it is JIS folding, data indicating A2, end face folding, JIS vertical folding mode is transmitted to the unit 20 (278).

If the size is not A2, proceed to step 279 to see if it is A3.

If the size is A3, the vertical / horizontal designation bit of the OBR is referred to, which indicates the vertical (280) and the unit 20.
Send A3, portrait, pass mode to (281). When it indicates the side, refer to the OBR fold selection bit (28
2) If it is unbroken, it sends A20, A3, Transverse mode to unit 20 (283). If something is wrong, the unit 20 is sent an A3 90 ° turn mode.

When the size is A4 (285), the vertical / horizontal designation bit is referred to (286), and if it indicates the horizontal direction (286), A4 / horizontal / pass mode is transmitted to the unit 20 (287). .
If it does not indicate the side, the A4 / 90 ° turn mode is transmitted to the unit 288 (288).

If the size is B, step 28, and step 27 above.
Similarly, the mode is transmitted to the unit 20 according to the size and the like. Step 27: A2 to B3, A3 to B4, A4 to B5
The contents of step 28 can be read as

As described above, when the unit 20 is ready, the unit 10 gives the control operation mode instruction to the unit 20,
It will be set in 20 microprocessors.

The CPU 14 of the unit 10 then proceeds to the blade folding mode setting (29) in FIG. 7d. In this step 29, first, the folding selection bit of the operation board register OBR is referred to (291,292,29).
Four). Then, when there is no folding, size data is attached and the passage is transmitted to the unit 30 (295). 4 folds, 2 folds,
In the case of JIS folding, the data of the size designation bit of the operation board register OBR and the data of the folding selection bit are transmitted to the unit 30 (293,296). This completes units 10 to 3
The control operation mode instruction is given to 0 and is set in the microprocessor of the unit 30.

When you finish setting the blade folding mode (29), CPU1 of unit 10
At 4, the punch mode is set (30).

In this, referring to the data of the size designation bit, the data of the folding selection bit and the data of the punch selection bit of the operation board register OBR (301 to 306, 308, 309),
Unit 40 when the final size is A4 and there is punch
Send A4 / punch mode to (307) and final size is B5
Moreover, when punching is present, the B5 / punch mode is transmitted to the unit 40 (310), and in other cases, the non-punch mode is transmitted to the unit 40.

When punch mode setting (30) is completed, CPU 10 of unit 10
At 4, the stamp mode is set (31).

In this case, referring to the stamp selection bit of the operation board register OBR (312), if it is 1 indicating the stamp, the unit 50 informs the unit 50 of the stamp selection bit, stamp position bit, issuer selection bit and The data of the drawing type selection bit is transmitted (313). If the stamp select bit is 0, it sends a non-stamp signal to unit 50.

When the stamp mode setting (31) is completed, the CP of unit 10
U14 sets the discharge mode (32).

In this case, referring to the paper discharge selection bit of the operation board register OBR (321), if it is 1, the unit 60 is instructed to discharge paper to the sorter, and when the discharge mode setting (32) is completed, This means that all the control operation modes have been instructed to 20 to 60, and the CPUs of these units hold the received instructions (mode data) respectively. The CPU 14 of the unit 10 is then the 7b
Returning to step 24 in the figure, the process proceeds to step 25 through step 24. Here, the data of the previous operation board register POBR is
Operation board register OB by execution of previous step 26
Since it matches the R data, the process proceeds from step 25 to step 33. In step 33, all the indicator lamps of the abnormality display panel 33 are turned off, the standby indicator lamps of the operation board 12 are turned off, and the ready indicator lamps are turned on. Next, the ready signal is output and set to the copying machine 800 (34). Then, returning to step 5 in FIG. 7a, the copying machine
Wait for signal from 800 and key-in of operation board 12.

When the start signal arrives from the copier 800 (6), the ready / standby bit of the operation board register OBR is referred to (3
5) If it is 1, normal operation is possible, so start signals are sequentially transmitted to the units 20 to 60 at a predetermined timing (37). Then, again, the process proceeds to the state reading below the step. Upon receiving the start signal, each of the units 20 to 60 starts driving the transport roller and waits for the arrival of the paper at the sensor. When the paper arrives, a predetermined control operation is started.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 20 is in standby (cannot process) or is in standby, the CP of the unit 10
U14 reads this in step 14 of FIG. 7b, and proceeds to the abnormality processing (15) of the unit 20. In this abnormality processing, first, the copier input bit of the operation board register OBR is referred to (151). If it is 1, data is received from the copying machine 800 and an abnormality (standby) is transmitted to the copying machine 800 because the sheet processing has started or has already started (152).
Then, the ready / standby bit of the OBR is set to 0 indicating that the operation is not possible, the ready indicator lamp of the operation board 12 is turned off, and the standby indicator lamp is turned on (153). Next, the abnormal data is received from the unit 20 (154), and if the abnormal data indicates a paper jam, the abnormal display panel corresponding to the position data is displayed.
13 Turn on the upper indicator lamp (156). When the abnormal data indicates that it is not a paper jam, all the indicator lights of the display panel 13 associated with the abnormal mechanism unit are turned on (15
7). Then, the process returns to the state reading after step 5 in FIG. 7a.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 30 is in a standby state (not processable) or in a standby state, the CP of the unit 10
U14 reads this in step 16 of FIG. 7b, and proceeds to the abnormality processing (17) of the unit 30. This abnormality processing (17) is similar to the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 30.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 40 is in standby (not processable) or is in standby, the CP of the unit 10
U14 reads this in step 18 of FIG. 7b, and proceeds to the abnormality processing (19) of the unit 40. This abnormality processing (19) is the same as the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 40.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 50 is in standby (cannot process) or is in standby, the CP of the unit 10
The U14 reads this in step 20 of FIG. 7b, and proceeds to the abnormality processing (31) of the unit 50. This abnormality processing (21) is the same as the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 50.

Before or after the control unit 10 gives a start signal to the units 20 to 60, if the unit 60 is in standby (cannot process) or is in standby, the CP of the unit 10
U14 reads this in step 22 of FIG. 7b, and proceeds to the abnormality processing (23) of the unit 60. This abnormality processing (23) is the same as the above-mentioned abnormality processing (15). However, unit 20 of (15)
Should be read as unit 60.

The operation of the vertical folding mechanism unit 100 and the operation of the 90 ° turn control unit 200 provided by the vertical folding & 90 ° turn control unit 20 have been described in the respective mechanism description sections. Therefore, the description of the control operation of the unit 20 will be omitted here because it is redundant.

Further, the operation of the blade folding mechanism unit 300 provided by the blade folding control unit 30 has been described in the mechanism description section of the unit 300. Therefore, the description of the control operation of this unit 30 will be omitted here because it is redundant.

The control operation of the punch control unit 40 and the control operation of the stamper control unit 50 will be described later.

The control operation of the vertical conveyance & discharge control unit 60 is to drive the paper conveyance roller, detect paper jam, and gate claw 712.
The positioning control is simple and can be easily understood by those skilled in the art from the mechanical description of the units 600 and 700, and therefore the description thereof is omitted here.

Next, the control operation of the microprocessor of the stamp control unit 50 will be described with reference to FIGS. 8a and 8b.
See also Figure 5a.

First, refer to FIG. 8a. Unit 50 when powered on
The microprocessor (hereinafter, simply referred to as CPU) executes initialization (91) and status reading (92). Therefore, if the sensor 598 detects paper (93), the unit 10
Send the paper jam to (94). And status reading (9
While doing 2), wait for the sensor 598 to become the paper non-detection state.

If the sensor 598 does not detect the paper in the status reading (92), the detection status of the sensor 536 is referred to (95). Sensor 5
When 36 is in the light detecting state, since the stamper's printing tool is not in the home position, the forward rotation energization of the pulse motor 520 is started and the rotation amount counting is started (96). And the sensor
When the status of 536 and the amount of rotation are read (97a, 98), and the sensor 536 is in the light-shielded state, the printing tool has reached the home position and motor 520 is stopped. Yes (97b). It is abnormal when the rotation amount reaches one rotation without the sensor 536 being in the light-shielded state. Therefore, the motor 520 is stopped (99), a mechanism abnormality is transmitted to the unit 10 (100), and the power is cut off. (101).

If the sensor 536 is shielded from light, then the state of the sensor 547, which is the detection means, is referred to (102). When the sensor 547 detects light (reflector 545), the second printing cylinder 541 (printing surface of the publisher) is at the home position.

If the sensor 547 does not detect light, the second printing cylinder 541 is set to 1
Step forward (103). This is done as follows. First, the solenoid 555 is energized so that the latch claw at the tip of the arm 553 advances to the base of the latch wheel 543, and then the pulse motor 5
20 is reversely rotated by a predetermined angle, then the energization of the solenoid 555 is cut off, then the pulse motor 520 is forwardly biased by the predetermined angle, and a stop constraint current is supplied to the motor 520. As a result, the second printing cylinder 541 rotates 360 ° / 5 = 72 °, and the printing surface is fed by one step. Sensor 536
Has returned to the shading state.

When such one-step printing surface feeding is completed, the feeding step counter is incremented by 1 and the count value (feeding step amount) is compared with 4 (104). If it is not 4, the state of the sensor 547 is referred to again, and if it is light-shielded, the printing surface is fed once again. In this way, the printing surface is fed step by step until the sensor 547 is shielded from light. When the sensor 547 is shielded from light, the second printing cylinder 5
41 is set to the home position (printing position is the first issuer).

If the sensor 547 is not shielded from light even after performing the step feed four times, it is determined that the mechanism is abnormal, the mechanical abnormality is transmitted to the unit 10 (100), and the process proceeds to the abnormality standby (101).

When the second printing cylinder 541 is in the home position,
The home position set of the printing cylinder (printing surface of the drawing type) 540 is determined and when there is no home position, the home position set is set to the second printing cylinder.
Similar to the home position setting of 541, it is performed by referring to the state of the sensor 547 which is the detecting means (105, 106, 107).

If the first printing cylinder 540 is also in the home position, the unit 1
It sends ready to 0 (108), waits for the arrival of a signal from the unit 10 (109), and receives the signal from the unit 10 (110).

Next, proceeding to steps 111 and 112 in FIG. 8b, if the received signal is data, the data is stored in the mode register (11
3) Referring to the contents of this data (114), if a stamp is designated, the stamp-issued stamp data (first to fifth stamp numbers) and the current position (first stamp) The original mark number = 1) is compared (115), and if they do not match, the second printing cylinder 541 is step-driven (116).
The step driving operation of this step driving is step 103.
Is the same as For example, if the data designates the third printing surface, 3-1 = 2, and 2 steps are driven, and 3 is stored in the position register. When the current position is the third print surface (position register = 3) and the first print surface is specified,
Three steps are driven with 1-3 = -2 and 5-2 = 3. Next, the drawing seed mark data (the numbers of the first to fifth drawing seed marks) and the current position (the number of the first drawing seed mark = 1) are compared (115),
If they do not match, the first printing cylinder 540 is step-driven (118). This print side setting is also similar to the setting operation in step 116.

When the setting of the printing surface is completed, the ready is transmitted to the unit 10 (108) and the start signal from the unit 10 is waited for (109, 110, 111).

When the start signal is received from the unit 10, the roller 582
Is set to the driving state, the timer Ts is set (119),
Wait for the sensor 598 to detect the paper or for the timer Ts to expire (120, 121). Paper does not come T
If s timed out, was there any trouble in the mechanical units up to the stamp mechanical unit 500?
If it is considered that the copying machine 800 has changed its status such that copying is not started, or that the feeding has ended (end), the roller drive is stopped (122), and standby is sent to the unit 10 (123). Proceed to read 92. After this process, the unit 500 is in the ready state,
Immediately after that, in step 108, send ready to unit 10,
It will wait for the start signal to arrive again from the unit 10.

When the start signal arrives and the sensor 598 detects the paper before the timer Ts times out (120), the contents of the mode register are referenced (124). The timing pulse number corresponding to is set and the pulse down count of the encoder 730 is started (125). Then, it waits until the count value becomes 0 (126). When the count value becomes 0, the pulse motor 520 is forwardly biased in synchronization with the pulse of the encoder 730 to start counting the rotation amount of the motor (12
7).

The contents of this pulse motor rotation energizing subroutine 127 are
A detailed description will be given here.

First, the forward rotation of the pulse motor is started with a predetermined acceleration pattern, the forward rotation amount count is started, and the paper discharge mechanism unit
Measure the time for one rotation of 700 rotary encoder.
The paper feed speed of the paper discharge mechanism unit 700 is set to the same speed. This time is measured by setting a 0.6msec timer until the number of pulses (slits) generated by one rotation of the rotary encoder is counted up,
When it times out, the time counter is counted by 1 and the 0.6 msec timer is reset. The content of the time counter when the value of the rotary encoder generated pulse counter reaches the value for one rotation indicates the feed speed (more precisely, its reciprocal). When the feed rate data is obtained, the timer value associated with the feed rate is read from the ROM and set in the register. When the acceleration is completed, the timer value is set in the timer register, and when the time is over, the energizing phase signal of the pulse motor is switched to the next one and set in the timer register. This operation is repeated until the content of the forward rotation amount counter becomes PV.

When the normal rotation driving amount becomes PV, this subroutine 127 is exited.

Now, when the drive amount reaches the specified value PV, the printing surface is
Since it has arrived just before, the solenoid 578 is energized to pull up the roller 572 (129). This starts the stamp. After that, the forward rotation of the motor 520 is continued, and when the sensor 536 is shielded from light (130), the printing tool returns to the home position, so the motor 520 is stopped and the solenoid 5
The energization of 78 is cut off, and a stop constraint current is applied to the motor 520 (131). As a result, the rotary member is stopped and locked at the home position, and the positional displacement does not occur. When the stamp is not instructed, neither the motor 520 nor the solenoid 578 is energized.

Figure 8c shows the stamped image. Of the printing positions on the paper, the position from the front end of the paper in the feeding direction is determined by the value set in the counter in step 125. The printing position in the direction orthogonal to the paper feeding direction is determined by the position of the base frame 502 in the orthogonal direction.

Next, the excellent points of the above-described embodiment will be summarized and described.

(1) The processing mechanism is a unit section, and the jammed paper can be removed, inspected, and repaired for each unit section. Since each unit has a grip for manual paper ejection,
You can remove jammed paper in units.

(2) The stamp mechanism unit 500 has a polygonal printing cylinder 54.
Since 0, 541 are provided, and these are rotated by the solenoids 554, 555 and the printing tool drive motor 520, the number of mechanical elements for updating the printing surface is small and the apparatus is compact.

(3) The printing cylinders 540 and 541 are polygonal, and the printing tool rotary shaft 5
Since it is installed eccentrically from 10,528, only one printing surface set at the printing position is stamped during one rotation of the printing tool (one rotation of 510). The paper is clean. The printing cylinder 54
The printing rubber carrying side of 0,541 may not be a flat surface, but may be a curved surface curved in an arc shape.

(4) The stamp roller 572 can move back and forth, and the solenoid 578
In the advanced position, the paper is slightly pushed up from the transport surface toward the free rotating wheel, and in the retracted position, it does not contact the printing surface. Therefore, even if the printing tool rotates, if the stamp roller 572 is in the retracted position, the roller 572
Does not get stained with ink.

(5) Since the printing tool drive motor 520 is a pulse motor and a stop constraint current is applied during stop, the stop constraint (positioning) of the printing tool is reliable.

(6) Since the printing tool drive motor 520 is a pulse motor and is driven in synchronization with the paper feed synchronization pulse (encoder pulse) at the time of stamping, the paper synchronous drive of the printing tool is accurate and simple.

(7) The position of the base frame can be manually adjusted in the direction orthogonal to the paper feed direction, and the stamp position in this direction can be adjusted and set. The stamp position in the paper feed direction is automatically determined according to an electric signal and can be set by a switch.

(8) Since the ink roller 560 is removable from the base frame and the stamp mechanism unit 500 can be pulled out from the main body of the sheet processing machine 900, it is possible to remove dust from the ink roller 560 and supply new ink to the rotor 560. It's easy.

(9) Date The date of the printing position of the printing device is set in unit 50.
With 0 pulled out, the manual rotating wheel 522 can be rotated to update in the manner shown in FIG. 5c. Since the mechanism unit 500 can be pulled out freely, this date change is relatively easy.

(10) A control unit is provided, and an operation board control unit is provided, and the operation board control unit serves as a main control unit and the other control units serve as slave control units, and paper size, posture, folding type, punch necessity, stamp, and stamp. Data indicating the necessity, stamp contents, etc. is given to the operation board control unit from the operation board and / or a host such as a copying machine, and the operation board control unit judges the stamp processing mode, and the slave control is performed based on the determined processing mode. Determine the processing mode of the unit and send it to the slave control unit. Therefore,
The control operation of the slave control unit is relatively simple. The slave control unit controls the sheet processing control of the mechanical unit, the paper jam judgment and the abnormality judgment, and the jam and the protection stop at the time of the abnormality and the transmission of this to the main control unit. You can do it. The entire movement of the sheet processing machine 900 and the movement of the mechanical unit are matched, the response at the time of trouble is quick, and the seriousness of the trouble is prevented.

(11) When the signal and data obtained in the setting state of the host such as the copying machine 800 and the signal and data obtained in the setting state of the operation board are duplicated, the operation board control unit extracts the former with priority over the latter. However, the signals and data that cannot be obtained from the host are obtained in the setting state of the operation board, and the data that is the basis of the processing mode determination is prepared.

When the sheet processing machine 900 is connected to a host such as the copying machine 800, the data given by the host is more reliable, and the processing should be started according to the start signal from the host. Therefore, the signal and data processing described above is rational, and there are few errors in judgment and processing. Also, the operation of the host and the operation of the stamp device are synchronized or matched.

If the host is not connected, it operates according to the input of the operation board, so that the stamp device can be used alone.

As described above, according to the present invention, when the control means (50) biases the stopper drive means (554, 555), the latch wheels (542, 54)
3) is stopped and restrained by the stoppers (552, 553). Since the latch wheels (542, 543) are fixed to the printing cylinder (540, 541) and the printing cylinder (540, 541) is pivotally attached to the rotating member (512, 526) which is rotationally driven by the motor (520), the control means (50) is the motor. When the (520) is activated, the printing cylinder (540,54
The rotating member (512,526) rotates while 1) is stopped, and when the motor (520) stops, the latch member (548,549,551) stops the rotating member (512,526) against the latch wheel (542,543) at the rotation position of a predetermined angle unit. to bound. As described above, the printing surface occupying the position (printing position) most protruding outward from the rotation center of the rotating member due to the eccentricity of the printing cylinder (540, 541) is changed.

In this way, by energizing the stopper driving means (554, 555) and rotationally energizing the motor (520), the printing surface at the printing position is updated. This update is for latch members (548,549,55
Because of the existence of 1), it becomes a step of a predetermined angle unit, so by aligning the printing surface with this, each printing surface is in the form of step rotation at the printing position (the position most protruding outward from the rotation center of the rotating member). Accurately positioned.

When the apparatus power is turned on, the printing cylinder (540, 541) is first positioned at a predetermined position (for example, the home position) with respect to the rotating member (512, 526) by the above-mentioned stamp surface update, and the control means (50) grasps the position of the stamp surface. To do. After that, the printing surface at the imprinting position can always be specified from the rotational direction of the printing cylinder (540, 541) and the number of times of renewal feeding, so that the printing surface can be accurately selected and set.
