Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a synchronization control device for rotary printing processing equipment, and more particularly, to a synchronization control device for, for example, a rotary printing machine and a groove cutting machine installed in a corrugated sheet manufacturing line. The present invention relates to a control device that can automatically synchronize reference points individually set for each rotating body with high precision in a multifunction device (rotary printing processing device).

Conventional technology: Flexo printer slotters (combined equipment with a multicolor rotary printing press and groove cutting machine) and flexo printer die cutters (combined equipment with a multicolor rotary printing press and a punching machine) used in corrugated sheet manufacturing lines. In a complex device equipped with a plurality of rotary cylinders of equal diameter or mutually different diameters in series, each rotary cylinder has its own reference point with respect to its operating point, and as a series of processes progresses over time. Therefore, it is extremely important that each reference point is accurately synchronized so that each reference point sequentially arrives at the corresponding operating point in a timely manner.

However, each of the constituent units of the multifunction device (hereinafter referred to as "rotary printing processing device") is configured to be able to be separated from each other for operation preparation and inspection, and each cylinder is equipped with a printing plate, a die board, and a groove cutting blade. It can be freely rotated independently for position adjustment. Therefore, when the above-mentioned setting operations are completed and the units are reconnected, the relative positions of the reference points of the rotating cylinders will be random. Therefore, it becomes necessary to synchronize the series of reference points prior to its operation.

This relationship will be explained with reference to FIG. 1, which shows a flexo printer slotter. This flexo printer slotter includes a first printing unit 14 which is equipped with a paper feeder 10 and a plate cylinder 12 rotatably provided.
and a second stage printing unit 18 provided with a plate cylinder 16;
Creaser unit 22 provided with ruled line head 20
and a slot unit 26 provided with a grooving head 24. Each unit is connected to a common rail 2 so that they can be connected and separated from each other.
8 via wheels 30.

The plate cylinders 12 and 16, the ruling roll 20, and the grooving disk 24 (some of which cannot be strictly called cylinders, but for convenience, they will also be referred to as "rotating cylinders" below) are each designated by the symbol b. ₁ , _b2 ,
At each bottom dead center indicated by b ₃ and b ₄ , printing, lining, and grooving functions are performed. Therefore, the cardboard sheet 3 on the paper feeder 10
2 is supplied, when the tip of the sheet 32 reaches the bottom dead center of each rotating cylinder, it is necessary to adjust the unique reference point of the cylinder so that it also reaches the bottom dead center. .

In this way, the reference points of multiple rotating cylinders are
In this specification, performing a sequence operation so that the corresponding bottom dead centers are reached in a timely manner is referred to as "synchronizing the reference points". The "reference point" here means, as shown in FIG. Indicate the position on the outer periphery of the cylinder in the opposite direction of rotation by the straight line distance to bx, and indicate this with the symbol P.

As mentioned above, the units are separated from each other for work preparation and inspection, and after each rotating cylinder is freely rotated independently, the units are reconnected. Therefore, the reference distance of the reference point P of each rotating cylinder from the corresponding bottom dead center deviates, making it impossible to achieve synchronization. For this reason, in the past, when each unit was separated, it was necessary to rotate each unit's cylinder drive gear manually or by an electric motor to set it at a predetermined reference position, and then to connect them. It is said that

Problems to be Solved by the Invention However, since the driving gears are not necessarily set accurately at the reference position, meshing errors occur in the series of gear trains after they are combined, and perfect synchronization is often not achieved. I made it. Therefore, it is necessary to supply the sheet many times for trial cutting, which requires complicated operations and a lot of adjustment time. In addition, when synchronizing with an electric motor, a dedicated electric drive mechanism is required for each unit, which increases manufacturing costs and increases the
(Numerical control) It has many drawbacks, such as difficulty in terms of operation and accuracy.

Purpose of the Invention The present invention has been proposed in view of the drawbacks inherent in the reference point tuning control means according to the prior art described above, and is intended to solve these drawbacks by randomly recombining separated units. It is an object of the present invention to provide a means by which the reference points can be synchronized instantaneously and with high precision by a simple operation.

Means for Solving the Problems In order to overcome the above problems and achieve the intended purpose, the present invention provides a sheet feeding device that feeds a large number of corrugated sheets stacked in an array to the downstream side one by one substantially horizontally; A rotary printing machine is equipped with a plate cylinder and an impression cylinder that rotate in opposite directions, and performs desired printing on corrugated paperboard sheets supplied from the sheet feeding device. A corrugated sheet processing machine that performs slotting etc. on a corrugated sheet using a pair of cylinders rotating in opposite directions; A first sensor detects the starting point of feeding the corrugated cardboard sheet to obtain a pulse signal, and a second sensor detects the reference point of each plate cylinder or cylinder to obtain a pulse signal. rotary printing of a corrugated cardboard sheet, in which the direction of the phase difference between these pulse signals is determined, and the differential mechanism is controlled to rotate forward or reverse depending on the direction, so that the phase difference approaches zero. In the processing device, a reference point for each of the plate cylinders and cylinders having different diameters is set from an arbitrary sheet feeding start origin provided between the sheet feeding device and the rotary printing press to each plate cylinder or cylinder. The straight line distance to the bottom dead center as the corresponding processing start point is determined from the corresponding bottom dead center to a position on the outer periphery of the plate cylinder or cylinder that returns in the opposite direction of rotation, and this reference point is determined as described above. A rising edge is integrally formed on the outer periphery of a coaxial drum set to have approximately the same diameter as each plate cylinder or cylinder, and the second sensor is attached to a frame that rotatably supports the plate cylinder or cylinder. It is characterized in that it is disposed at an outer position corresponding to the reference point.

Embodiment Next, a synchronization control device for a rotary printing processing apparatus according to the present invention will be described below with reference to a preferred embodiment and the accompanying drawings. As a specific example of a rotary printing processing device, the flexo printer slotter shown in Fig. 1 will be described, but other examples include a flexo printer die cutter consisting of a rotary printing press and a punching machine, and a rotary printing machine with grooves. Of course, the present invention can also be suitably applied to a so-called flexo die cutter slotter, which combines a cutting machine and a punching machine and can selectively perform printing groove cutting or printing punching. The present invention also provides a differential mechanism for adjusting the phase of a rotating cylinder (for example, the trademark "Harmonic Drive").
Although it is applied only to devices that are already equipped, most of the current rotating units such as multicolor rotary printing presses and flexo printer slotters are equipped with the above-mentioned differential mechanism for phase adjustment. There is no concern that the application of the present invention will be limited.

First, prior to explaining the details of the embodiment, a theoretical analysis will be performed with reference to FIG. 2, and then an example of the mechanical configuration of the control device and its control circuit will be described. FIG. 2 is a schematic diagram showing the arrangement of the rotating cylinders of the apparatus shown in FIG. The distance to the plate cylinder bottom dead center b ₁ of unit 14 is 827
Assume that the distance to the plate cylinder bottom dead center _b2 of the second printing unit 18 is 1387 mm, and the distance to the cylinder bottom dead center bx of any rotating unit in the front in the sheet feeding direction is X mm.

In this case, the leading edge of the cardboard sheet 32 in the paper feeding device 10 is 827 degrees from the point a of the paper feeding roller 34.
mm, the printing reference point P ₁ of the plate cylinder 12 reaches the bottom dead center b ₁ , and when moving forward 1387 mm from point a, the printing reference point P ₂ of the plate cylinder 16 reaches the bottom dead center b _2. Similarly, when moving forward by X mm from point a, if the operating reference point Px of the rotating cylinder reaches the bottom dead center bx, each reference point P ₁ ...Px becomes the corresponding bottom dead center b ₁ ...bx. This means that they are in sync. Therefore, on the circumference of each cylinder, a position P ₁ returned from the bottom dead center position by the corresponding distance in the opposite direction of rotation,
P ₂ ...P _x may be used as the operating reference point for each cylinder.

Therefore, converting the reference point of P ₁ ...Px into the rotational phase angle of each cylinder, since the circumference of each cylinder is 1400mm as mentioned above, the rotational angle of plate cylinder 12 = ₁ = 360 x 827 /1400=212.6° Rotation angle of plate cylinder 16 = ₂ = 360 x 1387/1400 = 356.6° Rotation angle of any cylinder in front = x = 360 x x / 1400 Therefore, the tip of the corrugated cardboard sheet 32 is the paper feed roller 34 The differential mechanism of each cylinder may be controlled so that the operation reference points P _{1 .} . . Px of each cylinder are at the corresponding reference positions when the sheet feeding start origin a is reached at That is, in order to perform this control, a sensor for detecting that the leading end of the sheet 32 has reached point a and a sensor for detecting that the reference point of each rotating cylinder has reached the corresponding reference position are provided, respectively. By matching the pulses of the detection signals obtained from these sensors, each reference point can be synchronized.

Therefore, an example of sensor arrangement and a control circuit for performing this tuning control will be described below. FIG. 3 shows an example of the arrangement of a sensor that detects when the leading end of the corrugated paperboard sheet 32 has reached the paper feeding starting point a on the paper feeding roller 34. That is, the corrugated cardboard sheets 32 stacked on the paper feeding table of the paper feeding device 10 are cranked by a pin 38 eccentrically protruding from a rotating disk 36 and a swinging arm 40 that engages with this pin 38. The sheets 32 are caught by a kicker 42 that repeats horizontal reciprocating motion at an inconstant speed, and are sent out in the direction of the arrow in order starting from the lowest sheet 32.

A pair of upper and lower paper feed rollers 34, 34 are disposed at the front in the sheet feeding direction, and the position where the leading edge of the sheet 32 is gripped by these rollers 34, 34 is defined as the paper feed start origin a. The paper starting origin does not necessarily have to be at this position, but the second
As shown in the figure, there is no problem even if it is at point a', which is a distance 〓 ahead of point a.

A rotary disk 46 is coaxially fixed to one of the gear trains 44 for driving the paper feed roller 34, and an arc-shaped protrusion 48 having a center angle of 180 degrees is arranged and fixed to the rotary disk 46. A first sensor 50 is disposed close to the rotation locus of the arcuate protrusion 48 . In this case, if the tip of the arcuate protrusion 48 is set to pass in front of the detection head of the sensor 50 when the tip of the sheet 32 reaches point a, then the point a of the sheet 32 can be The sensor 50 can detect the arrival of the target. A high-frequency oscillation type proximity switch is preferably used as the sensor 50, but a magnetic proximity switch (in this case, the arcuate protrusion 48 is made of a magnetic material),
A photoelectric switch may be used as appropriate.

In this way, the signal waveform of the sensor 50 with the arcuate protrusion 48 as a proximate object is a pulse waveform with approximately equal on time and off time, as shown in FIGS. 7 and 8, but as shown in FIG. As will be explained in connection with the control circuit, the front edge of the detection signal of the sensor 50 is used as a reference, and the signal width is only used to determine the operating direction of phase difference correction. Therefore, each of said on and off times is 50
It doesn't have to be %.

FIG. 4 shows an example of the arrangement of the second sensor for detecting when the reference point of each rotating cylinder has reached the corresponding reference position. In this case, the second sensor 52 is
As shown in FIG. 2, they are arranged at outer reference positions corresponding to reference points P ₁ . Specifically, the plate cylinder 12 of the first printing unit 14 is shown in FIG _. An arcuate protrusion 58 having a center angle of 180° with a rising edge thereof is integrally formed. A sensor 52 is arranged and fixed via a bracket 60 at an outer reference position corresponding to a specific reference point _P1 on the drum 56, and its detection head is placed close to the rotation locus of the arcuate protrusion 58. I'm making it happen. Therefore, the arcuate protrusion 58 whose rising edge is the reference point _P1
is detected by the sensor 52 located at the reference position, the reference point _P1 coincides with the reference position. As the second sensor 52, a proximity switch employing a high frequency oscillation type or other detection principle is preferably used.

Furthermore, regarding the application of the control device according to the present invention,
An example of the differential mechanism is shown in FIG. This FIG. 5 schematically shows the shaft support on the opposite side of the plate cylinder 12 shown in FIG. The barrel 12 is rotationally driven. A differential mechanism (for example, trademark "Harmonic Drive") 66 is attached to the tip of the rotating shaft 54, and the wave generator shaft 68 is connected to a differential motor 74 via gears 70 and 72. It's there. By driving the differential motor 74 forward and backward as appropriate, the plate cylinder 12 rotates independently, thereby making it possible to perform phase adjustment.

As shown in FIGS. 3 and 4, the sensor 5
0 and 52, respectively, the plate cylinder 12
When the cylinder represented by is rotated, signals having the waveforms shown in FIGS. 7 and 8 are obtained from the respective sensors 50 and 52. Both signals are on.
Although they are rectangular waves with substantially equal off-times, since the two signals are normally not synchronized, they appear with a phase difference, as shown in FIGS. 7 and 8. In other words, this is the "deviation amount" between the reference point of each cylinder and the reference position where the sensor is located. Therefore, if this phase difference is reduced to zero,
The reference points will be in sync.

The operation for bringing the phase difference between the two waveforms close to zero is performed by electrically controlling the differential motor 74. The operation of this tuning control circuit for electrical control will now be described with reference to an embodiment shown in FIG. This tuning control circuit is arranged for each rotary unit, and therefore consists of a number of tuning control units SCU ₁ to SCUx corresponding to the number of rotary units. In this embodiment, it is assumed that a flexo printer slotter is used, but since the creaser unit 22 does not need to tune the reference point, there are three tuning control units, SCU ₁ to _{SCU 3} . In this case, since the operating principle of each unit is exactly the same,
Only the synchronization control unit SCU ₁ used in the first printing unit 14 will be described. First, from the input to the output of the tuning control unit SCCU ₁ ,
The symbols and corresponding names of circuit elements are as follows.

NS ₀ ... Paper feed start origin detection sensor (code 50) NS ₁ ... Plate cylinder reference point detection sensor (code 52) PS ... Synchronization start push button M ₁ ... Differential motor (code 74) A ₁ ~A ₈ ...And gate O ₁ ~O ₂ ...Or gate F ₁ , F ₂ ...Flip-flop T ₁ ...Timer AM ₁ ~AM ₃ ...Amplifier FR, RR, OK ...Relay L ₁ ...Tuning complete Indicator lamp In the flexographic printer slot shown in FIG.
After completing the necessary work, both units 14 and 18 are connected. At this time, the plate cylinder 12
Since the reference point P ₁ of is shifted from the reference position,
As it is, a series of work processes such as printing and grooving cannot be started. Therefore, first, the main motor serving as a common drive source for each rotary unit is turned on, and the rotary cylinders are rotated all at once.

Then, taking the first printing unit 14 as an example,
As shown in Figs. 7 and 8, predetermined rectangular waves are generated with a phase difference from the paper feed start origin detection sensor NS ₀ (50) and the plate cylinder reference point detection sensor NS ₁ (52). do. In this case, FIG. 7 shows a state in which the plate cylinder 12 lags and is out of sync with the paper feeding timing, and FIG. 8 shows a state in which the plate cylinder 12 advances and is out of sync with the paper feeding timing. shows.
Here, the tuning activation pushbutton PB is pressed to input an ON signal to the AND gates A ₆ and A ₇ of the control circuit SCU ₁ shown in FIG. 6, and a negative input to the RS flip-flop F ₂ .

As shown in the circuit diagram, the signal from the paper feed origin sensor NS ₀ is input to the AND gate A ₁ and is negated to the AND gate A ₂ .
The signal of NS ₁ is inverted input to AND gates A ₁ and A ₂ , respectively. So, than the NS ₀ signal
When the NS ₁ signal is delayed, NS ₀ is high.
NS ₁ is low (Lo), and conversely NS ₁ is lower than NS ₀ signal.
When the signal is leading, NS ₀ is low and NS ₁
Assuming that is high (Hi), NS ₀ ° NS ₁ is input to S as a set condition in the RS flip-flop F ₁ , and NS ₀ and NS ₁ are input to R as reset conditions. Therefore, the output of flip-flop _F1 becomes a waveform obtained by adding the phase difference to the waveform of _NS1 , as shown in FIG. It appears like this.

In this way, the output waveform of flip-flop _F1 is
Phase difference = logic (positive/negative or high/low)
differs depending on the direction, so the later AND gate
By the combination of A ₄ and A ₅ , it is possible to determine the direction, that is, to determine whether the delay is out of synchronization as shown in FIG. 7 or the advance out of synchronization as shown in FIG. 8. That is, the output of AND gate A ₁ and the selection output of flip-flop F ₁ , which are signals corresponding to the phase difference 〓, are respectively input to AND gate A ₄ , and the output of the other AND gate
The output of the AND gate _A3 , which receives the _NS1 signal as an input and the _NS0 signal as a negative input, and the selection output of the flip-flop _F1 are input to _A5 , respectively.

When NS ₁ lags and must be in tune, AND gate A ₄ outputs, and when NS ₁ advances and is out of tune, AND gate A ₅ outputs. The outputs of these AND gates A ₄ and A ₅ are used by the subsequent AND gates A ₆ and A ₇
are input respectively. These and gates A ₆ ,
As mentioned above, each of the PB tuning activation signals is inputted to _A7 , and the dead band signal tz, which will be described later, is also inputted to each of them, so these AND gates _A6 ,
The conditions for each input will be taken in _A7 .

This dead zone signal tz is transmitted to prevent hunting operation and to distinguish between completion of tuning.
OR gate with NS ₀ and NS ₁ signals as inputs
This is obtained from the configuration of O ₁ and a timer T ₁ whose input is the output of this OR gate O ₁ . That is, since the NS ₀ signal and the NS ₁ signal have high and low levels due to their designed nature, "0" and "1" are periodically output to the OR gate O ₁ . Also, timer _T1 is designed to operate on the edge of the input signal from "0" to "1" and turn off after a short period of time, so it takes the pulse waveform shown in Figures 7 and 8. . The width of the minute time after this waveform rises is a dead zone, and since this affects operation accuracy, it is set as small as possible within a range where no hunting operation occurs. At this time, by inverting the dead band signal tz to the AND gates _A6 and _A7 , it is possible to prevent a situation in which a signal with a very small width is output to the gate output and a hunting operation occurs when the tuning is completed.

The outputs of the AND gates A ₆ and _{A 7} at the latter stage are amplified by the amplifiers AM ₁ and AM ₂ to operate the relays FR and RR connected to them, respectively, and the differential motor 74 is amplified by the amplifiers AM 1 and AM 2.
Rotate forward or reverse, and adjust the phase difference of the rotating cylinder 〓
Make adjustments to reduce the number of errors. Observing this as a whole as a logical progression in the control circuit, first of all, in the case of delay non-tuning shown in FIG. 7, the output of AND gate _A1 becomes "1" and flip-flop _F1 is set ( At this time, AND gate A ₂ outputs "0" and AND gate A ₅ does not operate). The output “1” of flip-flop F ₁ and the output “1” of AND gate A ₁ are AND gate A ₄
and its output “11” is input to AND gate A ₆
is input. Since the PB tuning activation signal "1" is input to this AND gate A ₆ , the output of the AND gate A ₆ becomes "1", and this output is amplified by the amplifier AM ₁ and is sent to the relay FR. The differential motor 74 is operated in the normal direction. As a result, the rotating cylinder is corrected in a direction where the phase difference 〓 becomes smaller, that is, closer to the reference point P ₁ (see the NS ₁ waveform).

In the case of _lead non-synchronization as shown in _FIG .
Reverse 4. By this, in Fig. 8
As shown in the NS ₁ waveform, the phase difference is corrected in the direction of decreasing.

In this way, the reference points are synchronized in each rotating unit, and in order to determine whether or not this synchronization is completed, an OR gate O ₂ , an AND gate A ₈ and a flip-flop F ₂ are provided. There is. That is, OR gate _O2 receives the outputs of AND gates _A4 and _A5 , respectively, and the output of OR gate _O2 is inverted input to AND gate _A8 . The dead band signal tz is also input to the AND gate _A8 , and the flip-flop _F2 uses the output of the AND gate _A8 as a set input, and uses the tuning start signal of PB as a negative reset input.

With this configuration, if the phase difference 〓 is larger than the dead band signal tz width (that is, if tuning is not completed), the input of the dead band signal tz is included in the negative input of AND gate _A8 . For,
No signal is output from the AND gate _A8 .
However, as the phase difference 〓 decreases, the dead band signal tz
When the signal becomes "0" within the width, the AND condition is satisfied and a pulse signal of the differential width is output, and therefore the flip-flop _F2 is set. The output of the flip-flop _F2 is amplified by the amplifier _AM3 to operate the relay OK, which causes the tuning completion indicator lamp _L1 to light up to indicate the completion of tuning.

Effects of the Invention As described above, according to the synchronization control device of the present invention, after the respective rotation units are arbitrarily and randomly coupled, the paper feed start origin detection sensor and the reference point detection sensor of each rotation cylinder By controlling the differential motor so as to make the phase difference in the waveform zero and aligning the reference point of each rotating cylinder with a predetermined reference position, the reference points can be synchronized easily and with high precision. The reference points for synchronization control between each printing press and the slotter, between the printing press and the die cutter, and between the slotter and the die cutter are set on a coaxial shaft having approximately the same diameter as the respective plate cylinders or cylinders. Since the configuration is required for the rising edge integrally formed on the outer periphery of the drum, it is possible to suitably perform synchronized control not only between cylinders of the same diameter, but also between devices having cylinders of different diameters. .
