Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a folding machine that folds continuous paper alternately while swinging it against a guide and sequentially stacks it on a paper table. The present invention relates to a method for sequentially lowering the paper table according to the amount of continuous paper loaded so that the surface height of the continuous paper stacked on the paper table is always maintained at a predetermined height.

(Prior Art and its Problems) Conventionally, business forms have generally been printed using high-speed form rotary presses. However, form rotary presses are very large and require a lot of time to change and adjust printing patterns, and many hl of waste paper are generated during these adjustments. Various offset tom printing machines have been developed.

When using folded continuous paper in this J: Unaform printing machine, it is common to place a folding machine on the exit side of the printing machine to fold and store the printed continuous paper. . For example, while swinging the continuous paper in a double-sided swinging guide with a narrow gap through which the continuous paper is inserted, each fold is
There is a folding machine that uses multiple spiral guides to alternately pick up the numbers and guide them downward as the spiral guides rotate. Continuous paper has 10 folds when guided in the direction of the spiral guide. The width of the spiral guy F was changed in response to the change in the ground position, and it was difficult to adjust the timing to fold it to 19th.
There are disadvantages such as 1. This is the simplest type of compaction machine that eliminates the above disadvantages.
It is possible to propose formula 13, which analyzes continuous paper at 7-pull and 10 times.However, in conjunction with the selection of the swing angle, the paper receiver is at the level of 1 side of the continuous paper at table 7. 'Proper 4C folding operation cannot be achieved unless the mutual distance relationship between the IFI and the lower end position of the swing guide is maintained accurately. For this purpose, continuous paper is loaded.
--It is necessary to lower the pull sequentially to keep the first surface height of the continuous paper of Solut at a predetermined height at all times. There is no one in existence that has achieved this exact operation with a simple configuration.

By maintaining the second predetermined height and controlling the swing angle of the swing guide and idler (paddle) 15, which will be described later, it is possible to perform an appropriate folding operation according to the vertical size of the continuous paper 12. .

In order to regulate the range of elevation of the paper table 16, first and second Lavre 1 switch 1719° 1720 and a table 1 switch 1721 are provided at predetermined positions in the rear box 1701.

There is an explanatory diagram C showing an example of setting the upper limit position of the paper table 16 when the vertical and vertical rises of 2 are [Q, J, Y, and K.]. As shown in FIG. 6C, the top and bottom of the continuous paper 12 (if the t-size is small), the swing angle α of the 3L1 paddle 15 is carefully set, and the upper limit position of the paper table 16 is set at the second position. The one-stop position is selected and the distance from the lower end of the paddle 15 to the paper surface F on the paper doublet 16 is set relatively large.

Further, as shown in FIG. 6D, when the vertical size of the continuous paper 120 is short, the swing angle α of the paddle 15 is set relatively small, and the upper limit position of the paper table 16 is selected at the 10th position. from the bottom edge of the paddle 15 to the paper table 1.

Upon initialization of the suction valve 14 (when the 4T suction valve shown in the figure is energized), the suction force switching solenoids 1418 and 1419 are switched to the solenoid 14191. :
As a result, the suction 1 conveyor 14 starts the suction bow 1 in the suction horn U-1 state with the auxiliary shutter 1415 closed.

The conveyor belt 1402 remains stopped. There is T.

FIG. 8 is a flowchart 1 to 1 showing the operation of the microprocessor 21 when resetting the paddle 15 to the home position.
It is. First, in step 5104, it is determined whether the standby position sensor (origin position sensor) 1727 has detected the origin position. If it has not detected the origin position, the process proceeds to step 5105, and the paddle pulse motor 1723 is activated to paddle by one pulse. This operation of moving the paddle 15 backwards is continued until the origin position is detected, at which point the initialization of the paddle 15 is completed.

Setting the continuous paper Next, as a preparation for printing, the operator sets the continuous paper 12.
The user who sets the continuous paper 12 on the pin feed tractor 13 uses the operation panel 25 to input the vertical size information of the set continuous paper 12 and the mountain/valley information representing the mountain fold/valley fold at the edge of the paper. At fillets 1 to 1 of the continuous paper 12, the operator presses the paper presser lids 1312 on the left and right sides.
．． Open (pull) 1313 and turn the lever 1306 in the relaxing direction (clockwise) to unlock 1302 from the moving tractor unit 1. Adjust the width of the left and right tractors according to the paper width until the paper edge is at the paper setting reference position. Next, engage the marginal punch of the continuous paper 12 with the paper conveyance pin 1311 of the left and right tractors, and then turn the lever in the tightening direction (counterclockwise direction) to lock the movable side trough conduit 1302. The paper presser lids 1312 and 1313 are closed, and the setting of the continuous paper 12 is completed.

FIG. 9 is an explanatory diagram showing the paper edge setting position of the continuous arc 12 that is pulled into the bin feed 1-actor 13. As shown in the figure, the paper edge of the continuous paper 12 is always set regardless of its vertical size. Set the paper at the paper setting reference position of the pin feed tractor 3 according to Pl.

As mentioned above, the pin feed tractor 3 is pre-positioned and mounted on the printing press body 1 so that the paper set position P is a predetermined distance -1H away from the printing start point P2. , when the paper setting is finished,
The paper edge of the continuous paper 12 is located a distance ('') from the printing start point P2.Then, when the paper threading of the continuous paper 12 set in this way is completed, or during printing, the continuous paper 12 When waiting for the next print,
The fold or perforation of the continuous paper 12 (that is, the beginning of the next page to be printed) comes to the standby position P3, which is an approach distance of 1111tl-(from the printing start point P2. In this way, P, P3 are the reference positions for paper conveyance during paper cut and printing, respectively, and must be detectable by the encoder, so the distance between P and P [2] is determined by the characteristics of the encoder used. For example, when using an encoder whose minimum detection unit is 1/2 inch, 1-12 must be an integral multiple of 1/2 inch. The above predetermined distance 11 is the sum of distance *t +-11.
As i1tH, the mounting position of the bin feed tractor 13 is determined. When the paper conveyance pin 1311 of the pin feed tractor 13 is detented (rotation prevention), if the continuous paper 12 is moved to the cellar 1, its leading edge will be at the P1 position.J: Adjust the paper conveyance pin 1311 beforehand. .

After the continuous paper 12 is fed to the bin feed tractor 13, the paper threading operation begins. FIG. 10 is a flowchart 1 to 1 showing the operation of the microprocessor 21 when executing a paper threading sequence.

Paper threading is started by inputting the paper threading key of the operation panel 25. Upon inputting the key, it is first determined in step 3106 whether or not a paper threading command can be accepted. For example, the top and bottom of continuous paper 12, 111.
If the paper threading sequence is not available (for example, when the paper threading sequence is not available), proceed to step 5107 and perform the operation. Is the operation complete? Zuru.

Paper threading command received (=l possible, suit part 3106
The process then proceeds to step 8108 to initialize each mechanical section C1. This swift 8108 is used when the paper threading routine is transferred from another routine, such as cleaning the blanket cylinder, to the paper threading routine. Since the initial settings of each part have already been made in response to the power being turned on, nothing is done in this step 8108.

Next, in steps 3109 and 3110, the C1 main motor 20 is started. There are two types of main motors 20, one for low speed and one for high speed.
At step 9, the low speed motor is turned on, and after a predetermined period of time has elapsed, at step 5110, the low speed motor is turned off and the high speed motor is turned on, ending the activation of the turn 1-20. As a result, the drive system in the main L-ray 20 starts operating, and the conveyor pel l-1402 of the suction-1 conveyor 14 starts conveying at a predetermined speed.

Next, go to knob 5113 and stop the drive of the DC (J-if tractor 192) of the bin feed tractor 13.
t, -t), the continuous paper 12 is stopped, and paper feeding is completed.

FIG. 11 is an explanatory diagram of how the continuous paper 12 is passed between the planks 1 and the cylinders 1 and 2 and the rows 1i11.

The blanket cylinder 2 is formed by tightly winding the sheet part 203 on the side surface of the blanket cylinder 202 with the open [-] part 201 to the right
Both ends are fixed to the frontage end portions 204 and 205 by a large number of screws (not shown) provided in the longitudinal direction. 1 rank l-1'12 is driven by the main sweater 20 [-for example, rotates at a constant rotational speed of 4500 r p l-1], and the old 11
is driven by Planckz l-11ii 2 by gears that mesh with each other on the cylinder side, and the blanket 11m
It rotates at a rotational speed corresponding to the ratio of the cylinder diameter to the second J'EI cylinder 11.

Now, the pressure 11 responds to the power supply by turning on the blanket 11.
Continuous paper 1 has been reset to the detuned position relative to ii2, and has been conveyed by the bin feed tractor 13.
The paper edge of 2 is 1 lanket t-drum 2 A3 and yJ: INJ
It progresses through the gap between 11 and 11. During printing, the M feed speed 111- of the continuous paper 12 is equal to the circumferential speed of the cylinder 2 to the planks 1 and the circumferential speed of +l:Ill 1 '1 'J <
For example, when printing 11, the paper feeding speed 1σ of M continuous group 12 during this paper threading is as described in 1.
) and 1/4 of J1 [Since the speed is low, when passing through the gap, the continuous paper 12 let Zoranketsu l-III 2 OJ
While being struck in the forward direction j1 by the pressure roller 111, the cylinder 1'1 is rotated by its own weight and is sent to the direction 1) of the conveyor 14 under suction.

If the paper is fed at the same speed as the circumferential speed of the blanket cylinder 12 or faster than the kneading speed, the trajectory of the paper edge and the phase of the blanket cylinder should be strictly controlled. III IJll b Otherwise, the continuous paper 12 would not only get into the tray 20 open [-1 part 2C] 1 and appear as 1, but also, for example, when printing on the paper (not shown by the imaginary line) Paper output row for pulling and peeling continuous paper 12 with two cylinders 206
If the top of the continuous paper 12 is
It is very important that the paper feed speed 11 of the J3C continuous paper 12 be made slower than the circumferential speed of the plane cylinder 2 when passing the paper. . By doing this, it is possible to temporarily set up the 11 paper rollers 206 without performing any elaborate control.
Even if the continuous paper 12 is damaged, the edges of the continuous paper 12 are not crushed.
This makes it possible to easily perform automatic paper threading.

Prankera l-11ii 2 do pressure 11 as described above.
The continuous paper 12 that has passed through the gap between the continuous paper 12 and the paper i11 is guided toward the folding machine 17 by the suction conveyor 14. The conveyance speed of the conveyor belts 14 and 02 of the suction conveyor 14 is set in advance to an appropriate constant value faster than the paper feed speed of the continuous paper 12 during printing, and the paper feed speed of the continuous paper 12 is currently 1 during printing. /4 slow speed, so continuous paper 12
is conveyed by the suction conveyor 14 while being subjected to tension.

This tension changes depending on the suction force of the suction conveyor 14, but during paper threading, this tension changes with the pin feed tractor 1.
Since the suction force is applied to the marginal punch of the continuous paper 12 engaged with the paper conveyance pin 1311 of No. 3, the suction force is set to the "medium" stage to prevent the marginal punch from being damaged. That is, as described above, in the initialization sequence when the power is turned on, the main shutter 14 of the suction conveyor 14
14 is in the "closed" state and the auxiliary V-shaped vine 1415 is in the "open" state to start suction.

Position of Paddle/Paper Table 1 On the other hand, in response to inputting the paper threading key of the operation panel 25, the paddles 15 and paper table 16 of the folding machine 17 are set at predetermined positions.

FIG. 12 is a flowchart showing the operation of the microprocessor 21 when the paddle position a is set, and FIG. 13 is an explanatory diagram schematically showing the set position and swing angle of the paddle 15. The swing angle α is changed according to the vertical and vertical movements of the continuous paper 12, and the microprocessor 21 graphically displays, for example, values corresponding to the required swing angle α based on the vertical and horizontal movements information inputted from the operation panel 25. Let it go to the counter. The paddle 15 swings from the reset position to the ``front'' position and ``back'' position, centering on the position where the center angle is β. When the key is inserted, first, in step 5114, β-α/2 is calculated. This angle is determined by moving the paddle 15 from the reset position to
This is the angle necessary to move the paddle to the "rear" position, and then in step 5115 the paddle pulse motor 1723 is driven by a pulse corresponding to the angle calculated above.
Setting the paddle position to the initial position is completed by moving the paddle to the "rear" position.

FIG. 1/1 is a flowchart showing the operation of the microprocessor 21 when setting the paper table 16 to the initial position. The upper limit position of the paper table 16 is changed according to the vertical size of the continuous paper 12, and the microprocessor 21
are two types of upper limit positions (the first
and second table upper limit switch 1719.
(upper limit position corresponding to 1720) is selected in advance. For convenience of explanation, it is assumed that, for example, the first upper limit position corresponding to the first table upper limit switch 1719 has been selected. When the paper threading key is turned on, first, in step 8116, it is determined whether the output of the first table upper limit switch 1719 is ON, that is, whether the paper table 16 is at the upper limit position. If it is at the upper limit position, go to step 8.
The process proceeds to step 117, where it is determined whether the output of the first paper surface detection photoelectric sensor 1717 is ON, that is, whether there is any remaining paper on the paper table 16 corresponding to the previous printing. If there is no paper on the paper table 16 (), the output J of the first paper surface detection photoelectric sensor 1717 is OFF, and at that time, the cell 1~ at the table position ends.

If there is paper on the paper table 16, the output of the first paper surface detection photoelectric sensor 1717 is turned ON, so step 511
7 to step 8118, the table lifting motor 1703 is driven, and the paper table 16 is lowered to a predetermined height. While the table is lowering, it is monitored in step 5119 whether the output of the table upper limit switch 1721 is turned ON, that is, whether the table has reached the lower limit position, and if the lower limit position has been reached, the process proceeds to step 5120.

If there are any remaining sheets, the paper table 16 will stop after the surface of the remaining sheets reaches a predetermined height due to the two steps.

Also, in the parable of the Daple, in step 5127, L
13, monitors whether the output of the first paper surface detection photoelectric sensor If table 1 (5) is turned ON, the process advances to step 5129 and the C counter is set to 1 (J step 1).Subsequently, in step 5130, it is determined whether the count value of the counter is 2 or more. In step 5130, it is determined whether the ON output of the first paper surface detection photoelectric sensor 1717 is obtained continuously, and if the count value of the counter is 2 or more, the paper surface is detected two or more times in a row. Since it has been detected, it is determined that there is no error in the detection, and the process proceeds to step $126 to stop the paper table 1G.Then, the operations from step 8118 described above are performed, but at this time, the first paper surface detection Since the output of the photoelectric sensor 1717 is already ON, the process immediately proceeds from step 5121 to step 5122 and the paper table 16 stops.
The upper surface of the remaining paper is set at a predetermined height.

When the count value of the counter is 1 in step $130, for example, the oblique portion of the remaining paper that has been threaded through the printing press body 1 from the paddle 15 to the paper lap 16 is detected by the first paper surface detection photoelectric sensor. 1717 may be detected, the process returns to step 5124 and the paper table 16 is placed in the -L position again. If the output of the first paper surface detection photoelectric sensor 1717 is ON again, I = J as described above.
: Proceed to the surface of the screen 512G and below, and bring the remaining paper l-side to a predetermined height to the sensor 1. In response to the input of the paper threading key, the No.C paddle 15 is moved to the "rear" position and the surface of the remaining paper on the paper table 16 or the paper table 16-1 is set at a predetermined height. , the continuous paper 12 is conveyed there by the action of the pyrenoid 1 heractor 13 and the suction 1 conveyor 14. 1st

As mentioned above, the MicroProsen 4J21 performs 1-rat- At some point, before the end of the paper reaches the folding machine and after the initial positioning of the paddle 1- is completed, the paddle pulse motor 1723 is driven to swing the paddle 15 up to the "front" position. Then, at the timing when the leading edge of the paper is conveyed to the position shown in FIG.
move into position. The first page of this continuous paper 12 is "later"
Due to the action of airflow generated on the back side of the paddle 15 as it is pulled into position,
The width of the paddle 15 is set to be smaller than the width of the continuous paper 12 in order to avoid the influence of wind pressure that tends to push the continuous paper 12 back to the "front" position at this time. It is desirable that it is wider. And (,b) the state shown in the figure is gone. After that, the continuous paper 12 advances approximately one page at a time (c),
At the timing of (d), move the paddle 15 sequentially to the "front" position and "
The paper edge setting is completed in the state shown in (d).

When the leading edge of the continuous paper 12 is folded into a "mountain" fold, the movement of the paddle 15 is opposite to the above-mentioned 1-valley fold. In other words, the microprocessor '21 does not operate the paddle 15 until the timing shown in FIG.
leave it as it is.

Then, at the timing (e), the paddle pulse motor 172
3 to move the paddle 15 from the "rear" position to the "front -1" position. (G), (h)
The paddle 15 is sequentially swung between the "rear" position and the "front" position at the timing shown in FIG.

FIG. 16 shows the operation of the microprocessor 21 when the paddle 15 is operated. This program is called and executed at an appropriate timing, and the timing reference may be, for example, a built-in hard timer, or a built-in hard timer (not shown) attached to the rotating shaft of the planchers 1 to 2. It may also be an output signal from a reference rotary encoder. When moving the paddle 15, first in step 5131 it is determined whether the current paddle position is the "front" position or the "rear" position. This can be identified, for example, by flagging the "previous" position. When the paddle 150 position n is "front", the process advances to step 5132 and drives the paddle pulse motor 1723 backward by the pulse amount corresponding to the count value corresponding to the swing angle α set in the counter. The paddle 15 is moved to the "back" position, and then the process proceeds to step 5133 with /u to record the position of the paddle 15 as "back", and the operation ends. When the current position of the paddle 15 is "rear", the process proceeds from step 5131 to steps 8134 and 5135, and the same operation as described above is performed to keep the paddle 15 from moving forward.

When the paper end of the continuous paper 12 is folded into the folding machine 17 as described above after the parallel paper threading is completed, the low-speed paper feeding stops, that is, the DC servo motor 192 of the pin feed tractor 13 stops. ), the main motor 20 continues to rotate and waits for the next command.

At this time, the beginning part (fold or perforation) of the 1201st page of continuous paper to be printed is No. 9 = 48
- It is at print standby position 1]3 in the figure.

When the print key on the operation panel 25 is pressed 1q times, the program proceeds to the printing program, where the routines of plate replacement, blanket cylinder cleaning, printing start, regular printing, and printing end are executed in sequence.

Further, in response to the input of the print key, the paper presser fan 30 starts rotating. The paper pressing fan 30 is configured to stop in response to the end of the printing program or in response to the output of the switch 1318 attached to the bin feed tractor 13 being turned off.

In the plate exchange routine, the plates (not shown) prepared in advance and placed on the plate supply/discharge trays 9 and 10 are changed to correspond to the corresponding plate IB? by the action of the unit 5.6. 3.4 is wound and installed, and at the same time the plate cylinder 3
．． The old plate (not shown) that was wrapped around the plate 4 is discharged onto the plate discharge tray on the corresponding plate supply tray 0. In the case of one-color printing, 131 printing is performed only on the necessary side.

In the blanket cylinder cleaning routine, first, from the cleaning liquid supply-L unit I to 18, turn on the blanket cylinder 1 at an appropriate timing.
~The cleaning liquid is supplied to the cylinder 2, and then the cleaning liquid is wiped off by the wiping unit 19 at the same time as the cleaning liquid is supplied intermittently.Finally, the supply of the cleaning liquid is stopped and only wiping is performed, and the cleaning of the cylinder 2 to 1 rank 1 is completed. .

Next, in the printing routine, the timing of inking between the ink roller and the plate cylinders 3 and 4 in the ink roller 1-7.8 is determined from the plate cylinder 3.4 to the plate cylinders 1 to 2. We actually printed two sheets of paper while appropriately controlling the timing of each transfer. 2. After adjusting the -L in/N-hang and bringing the printing density close to the steady value, enter the steady printing routine.

In the regular printing routine, Planckz l-1ti2

An output signal from a reference rl-tary]-n-'-da, not shown, mounted on the rotation axis of the -in 2 is used.

From this output signal (as shown in FIG. 17(f)), it is possible to know which phase the cylinder 2 is currently in to the Planckz 1. "o o" is the Planckz I-1612
The position of the person starts printing (indicates that the person is at the same location as J3)
At this timing, the terminal end 205 (see Fig. 11) of the blanket part 201 of the blanket [12] comes to the 4th cylinder position with the 1:) bottom I-+142 pressure I swell 11.
, the shaded area in () in Figure 17 (') is open [-1 part 20
It shows the timing when 1 passes the -51= printing start position, and in this example, 1/4 of the total circumference of 2 is the open L1 part, and the remaining 3/4 is said to be Planckz-do-right-effect-shu-en.

The impression cylinder 11 is put on at times t-12. That is, at timing t1, just after the starting end 204 of the frontage 201 of the blanket III 2 passes the printing start position shown in FIG. 201, gradually speed up the drive, and gradually loosen the drive again.
The pressure Ij 111 is slowly moved to the wearing position for a relatively long period of time until time 1-2 when the terminal end 205 approaches the printing start position.

At time 12 when the pressure Iji11 reaches the lower position,
Since the facing blanket 112 is in the phase of [-1 part, the continuous paper 12 is in phase with the blanket lim2 and I
Not nipped between f:1111. The nip of the continuous paper 12 starts when the end 205 of the opening 201 (see Fig. 11) reaches the printing start position (timing of "o o"). r) Printing is started.

At the timing of the incense notes 1 and 2 of the impression cylinder 11), the bin feed 1--D CIJ--bo motor 192 of the tractor 13 is in a non-driving state at 115') shown in FIG. 11 (1). Yes, the bin feed 1 hector 13 remains stopped and the continuous paper 12 is ready for printing. Furthermore, bin feed 1

As shown in (C) and (d), 9 is in the initial state in which only the auxiliary shift V vine tsurenoid 1419 is energized, and the shift 17 vine 1414 is in the f'[l state, ?

In the state, get the suction force of 14
J shown in (e) is at the uni i-medium-1 stage. The transport bells 1 to 1402 + of the suction conveyor 14 are driven by the main motor 20 and are traveling at a constant speed in the 411 paper direction (J), so the continuous paper 12 (bin feed tractor 1
An appropriate tension of 4f is applied between the suction tube 3 and the suction conveyor 14. The suction force in the "medium" stage during printing standby is preferably such that a tension that is strong enough to prevent the marginal punch of the continuous paper 12 engaged with the paper conveying pin 1311 of the bin feed tractor 13 from tearing can be applied. Select something.

Timing t just before II OOII when printing starts
3, the detent of the pin feed tractor 13 is released, and the DC servo motor 192 starts to be driven in the normal rotation direction, as shown in FIG. 3(b). At the same time, as shown in (d), the auxiliary shutter solenoid 1419 is de-energized to bring the auxiliary shutter 1415 into the "closed" state, and (e
), the suction force of the suction conveyor 14 is increased to the "large" stage.

As a result, paper feeding of the continuous paper 12 is started while applying a very strong tension, and the feeding speed of the leading edge of the first page to be printed starting from the printing standby position ffRP3 in FIG. 9 is changed to the printing start position P2 ( It reaches V, which is the same as the circumferential speed of the blanket cylinder 2, before the timing "00"). The leading edge of the first page reaches the printing start position P2 at the timing of 00'' after that -@ and is nipped between the blanket cylinder 2 and the impression cylinder 11, and from this timing of ``'o o'', a predetermined printing section starts. Printing is performed on one page of the continuous paper 12 until timing t4 when printing (corresponding to the top-to-bottom length of one page) is completed.

During printing, a very strong tension is applied to the continuous paper 12 by the above-mentioned suction force at the "large" stage, so the viscosity of the ink 111 causes the blanket [f! The continuous paper 12 stuck to the paper 2 can be easily peeled off. Therefore, there is no need to provide a paper discharge roller 206 as shown by the imaginary line in FIG. 11, and this is particularly effective when it is desired to print across the entire width of the continuous paper 12.

At timing t4 when the printing section ends, (a)
As shown in the figure, the pressure 1iJ pulse motor is started to be driven toward the front shell side. At this time, unlike when r:tIli1, the drive is quickly raised and lowered in a relatively short period, and a quick #tIli is achieved. Soshi'C impression cylinder 1
1 has returned to the female side position, and at the timing shown in (b), the normal rotation brake starts to be applied to the DC servo motor 92 of the bin feed tractor 3. At this time, (c),
J shown in (d): Main shutter solenoid 1418 and auxiliary shutter solenoid 1 of the sea urchin suction conveyor 14
419, the main shutter 414 and the auxiliary shutter 1415 are both in the "open" state, and the suction force is reduced to the "small" stage as shown in (e) to reduce the tension on the continuous paper 12. Keep it minimum.

Thereafter, at timing t6 when the feed speed of the bin feed tractor 13 reached zero, the DC servo motor 192 started to be driven in the reverse direction, and at timing 17, the reverse brake was started ( ), and at t8 when the reverse speed reached zero. At the same time, the reverse drive is stopped and the detent is activated. At timing t8 when the reversal is completed, the head of the second page of the continuous paper 12 is at the print standby position P3 in FIG. 9. That is, during the reverse feed between timings 16 and t8, the continuous paper 12 is pulled back by a distance corresponding to the run-up (timings t3 to 00) and overrun (timings 1-16).

During reverse feeding, the paper conveying pin 1 of the bin feed tractor 13
The suction force of the suction conveyor 14 is adjusted so that an excessive load is not applied to the marginal punch of the continuous paper 12 engaged with the paper 311.
Although the continuous paper 12 is in "small" stage, the action of the paper press fan 30 prevents the continuous paper 12 from floating up from the upper surface of the suction conveyor 14. Then, at timing t8 when paper feeding is completed, the power supply to the main shutter solenoid 1418 is stopped as shown in FIG.
Close the , and as shown in (e), set the suction force to ``Medium'' and enter the standby state for printing the next page.

Sequential lowering of paper table The continuous paper 12 printed while being fed intermittently as described above and discharged from the printing press main body 1 is sequentially folded and stored in a stack in the folding machine 17. MicroProcera 4 No. 21 is attached to the rotating shaft of Prankera 1 to cylinder 2, and an origin pulse (set at the time of 1 to 1 to normal rotation star 1-) is output from a reference rotary encoder (not shown) attached. The paddle swinging program shown in FIG. 16 is executed every time the page is printed, and the paddle 15 is moved r forward at a swinging angle α (see FIG. 13) that corresponds to the top and bottom rise of the continuous paper 12 every time one page is printed. After the Jr., the J position and the N position are alternately rocked. The operation at this time is similar to the case of threading the paper as described above.

The paper lap 16 gradually descends as the continuous paper 12 is piled up. FIG. 18 shows the operation of the microbroselli 21 when the paper table 16 is lowered at the 1st position - 1, and the microprosensor 21 is transferred to the planner 1 at the 7th position of y2. T, Q! This program is executed every time the origin pulse is output from the low-resolution encoder. The height of one sheet of paper is selected according to the top and bottom noise information as described above in connection with paper threading.
A case where the paper top surface height corresponding to No. 17 is selected will be explained.

First, in step 8136, the output of the first paper surface detection photoelectric sensor 1717 is ON, but somehow the output is ON.
It is determined whether the top surface of the paper has reached a predetermined height (-C) or not (-1:I'I).Proceeds to step 5137 and resets a counter (not shown) to t'![]. () () When the top surface of the paper reaches the predetermined height j\1.
If it almost reaches X, the first paper surface detection charging is turned on! N1J-17
When the output of 17 is ON: 7) 'l step 813
Proceed from step 6 to step 8138 and set the force 1゛nonta to 11.
Do IJ step forward? Next, in step 5139i, the output of the first paper surface detection photoelectric lens 1717 is turned ON and ( By making multiple detections as a line t in this way, the first paper surface detection photoelectric sensor 1717 detects the oblique portion of the continuous paper 12 hanging from the paddle 15. It is possible to avoid malfunctions when continuous paper 1
If it is the oblique part of No. 2, it is constantly swinging left and right, so there is no possibility that 5 collections of 1 m will be detected consecutively.

Then, if the count value of the counter is 5 or more, the height of the top surface of the paper on the paper table 16-1 has reached the predetermined height, so the process advances from step 5139 to step 5140 and the table is drives the prevention lever 1703 in the downward direction for a certain period of time, and moves the paper staple 16 a predetermined distance (for example, 5 rrv
n) or lower it. B()"C After resetting the counter to zero in step 5141, the operation ends. If the count is less than 5, the paper table 16
The operation ends without lowering the counter, but the counter is not reset at this time, and if the count value becomes 5 or more in subsequent executions of this program, the time point will be 0.
The paper table 16 will now be lowered. In this way, the height of the top surface of the continuous paper 12 corresponding to the vertical noise is always maintained.

d5 In the above description, the paper table sequential lowering method according to the present invention is applied in detail to an offset 1-form printing machine, but this invention is not limited to a form printing machine, but can also process folded continuous paper. It can be widely applied to machines in general, and in this case as well, the same effects as in the above-mentioned embodiments can be achieved. In addition, an embodiment was described in detail in which the paper table sequential lowering method 1 according to the present invention was applied to a folding machine that alternately folds continuous paper while swinging it by a swinging guide and sequentially stacks it on a paper table 11. This invention is effective not only for folding continuous paper, but also for sheet paper, where it is necessary to precisely control the height of the stacked top surface. This is particularly effective in the case of high-speed rotary presses, which require accurate control of the paper table.

(Effects of the invention) As explained above, according to this invention, paper can be used as a paper table! J: In the case of sequential loading, the light emitting side and the light receiving side of the photoelectric detector are arranged so that their optical axes are parallel to the table surface of the paper table and facing in the width direction of the paper. The paper tables are arranged opposite to each other at a predetermined height across the road, and when the detection output of the photoelectric detector continues for 10 seconds for a predetermined period of time, the paper table is lowered to a predetermined height. To put into practice a paper-table sequential lowering method capable of always accurately maintaining the height of the top surface of paper on paper tables at a predetermined height by lowering the paper table sequentially according to the loaded amount of paper. becomes possible.
