イミングが非常にむずかしい。2. Description of the Related Art In a printing press, a printing sheet is often not supplied from a sheet feeding device, or is supplied in a form of two sheets. In such a case,
Stopping machines that are running at high speeds in each case degrades cost performance, so printing cylinders are attached and detached to stop and restart paper feeding. However, it is very difficult to attach and detach the printing cylinder rotating at high speed without producing any wasteful printed matter.

ことがあり、安定性に不安があった。On the other hand, an apparatus having many components and many control parts, such as a printing press, has many wirings and is complicated, so a large wiring space is required, wiring mistakes, construction delays, maintenance complexity, parts prices and cost. There are problems such as high construction costs,
In recent years, control by multiplex communication has been performed. However, although this control method using multiplex communication has brought great benefits by drastically reducing the number of wirings, there is a problem in processing time with the conventional device, and it takes time for data transmission to attach and detach the printing cylinder. In some cases, the timing was shifted, and the stability was uneasy.

刷が行われる。That is, as shown in FIG. 5, printing cylinders such as the printing cylinder 5, the blanket cylinder 6, and the impression cylinder 7 have gap portions where printing cannot be performed. Plate holding unit 14 for attaching the printing plate, and blanket cylinder 6
Is a mounting portion 15 for a blanket to be wound around the surface, and the impression cylinder 7 is a claw device portion 1 for conveying the sheet 17 while holding the front end thereof.
6 and so on. Therefore, when the gap portion is at the contact portion between the printing cylinders and the cylinder is inserted or removed, printing can be performed from the beginning of the sheet 17 and printing is performed to the end.

要がある。However, the above-described gap portion 14,
Reference numerals 15 and 16 denote a gap portion of each of the printing devices 2a to 2n in consideration of machine vibration because when the gap portion comes to a contact point of the printing cylinder (a portion to which contact pressure is applied), pressure is lost and an impact force is transmitted. Are made different so that the contact point of the gap portion with the printing cylinder is different in each of the printing apparatuses 2a to 2n. For this reason, it is not possible to instruct the printing apparatuses 2a to 2n to attach / detach the cylinder at a single timing, and it is necessary to instruct the printing cylinders to attach / detach the cylinder at an individual timing.

n, one pulse for each rotation of the plate cylinder
(1 pulse / 180 degrees), and the rotation of the printing devices 2a to 2n is out of phase. When the body removal command signal is issued, there are places where the timing has a margin and places where there is no timing.
【0012】その上、印刷胴は高速で回転しているた

て動作が終了するまでの遅れ時間は、印刷機が高速にな
れば影響度が大きくなり、胴入れ、胴抜きは非常に短い
時間内に処理を行う必要がある。In addition, since the printing cylinder is rotating at a high speed, the transit time in the gap is very short. FIG. 2 shows the printing speed and the required processing time. As can be seen from FIG. 2, the delay time from when the cylinder attaching / detaching device 11 or 12 shown in FIG. The higher the speed, the greater the effect, and it is necessary to perform the processing for inserting and removing the cylinder within a very short time.

事前に胴の着脱の指示を出す必要がある。That is, for example, when the cylinder is to be punched out at a printing speed of 16,000 sheets per hour, one rotation of the cylinder is 0.225 seconds, and the gap portion (plate holding device unit) 1 of the plate cylinder 5 described above.
The time for 4 to pass is about 0.05 seconds. When the body attachment / detachment mechanism is of the air cylinder type 12, the solenoid valve is operated to operate the air cylinder, and the mechanical mechanism is operated. However, these operations take about 0.1 second. It is necessary to give an instruction to attach and detach the torso in advance.

れば、その合計は0.1秒になり、この伝送時間をも考
慮して事前に胴の着脱の指示を出す必要がある。However, in the control method based on the multiplex communication described above, a body removal signal is transmitted from the unauthorized paper feed detection device 19 to the body attachment / detachment control device (slave station) 26.
A data transmission time of, for example, about 20 msec is required to transmit to the information processing device (master station side) 21 by communication, and further, for example, 60 msec for calculation using the sequencer and the CPU in the information processing device 21, If it takes, for example, 20 msec to transmit the instruction for attaching and detaching the cylinder to the cylinder attachment / detachment control device (slave station) 26 of the printing devices 2a to 2n, the total is 0.1 second, and the transmission time is taken into consideration. It is necessary to give an instruction to attach and detach the torso in advance.

上述した近接センサ20の信号の数が少ないことから、
速度が遅い時は対応できたが、近年のように高速になる
と、この時間遅れや時間のばらつきが装置の作動安定性
を損なう大きな問題となる。In addition, this is an example of a case where transmission takes a long time. In an early case, the transmission may be performed in less than 0.01 second. There is a need. Therefore, because of this variation and the small number of signals of the proximity sensor 20 described above,
Although it was possible to cope with the case where the speed was low, when the speed became high as in recent years, the time delay and the variation in the time became a serious problem that impaired the operation stability of the apparatus.

り、安定性に不安があった。That is, when the speed of the machine increases, the signals to be transmitted and commanded need to have a margin as much as possible, otherwise the expected operation will not be performed. Conventionally, a timing shift may occur in some cases, and there has been a concern about stability.

御装置を提供するためになしたものである。In view of the above, the present invention makes use of the advantages of multiplex transmission and is stable without being affected by time delays and timing variations even when the speed of the machine is increased, and without producing wasteful printed matter. Accordingly, the present invention has been made to provide a control device capable of performing attachment and detachment of a printing cylinder.

Thus, it is possible to provide a control device capable of eliminating the transmission time between the master station and the slave station, which has been a problem in the multiplex transmission system, eliminating the shift in the timing of attaching and detaching the body and stably attaching and detaching.

への指令信号は、多重伝送によらず、直接胴着脱装置へ
伝達するので伝達遅れもなくなり、従来は胴着脱装置へ
の情報伝達に約0.1秒かかっていたのが約0.000
1秒以下になる。Further, a command signal from the cylinder mounting / dismounting control board (slave station) 27 to the cylinder mounting / dismounting apparatus as shown in FIG. 4 of each of the printing apparatuses 2a to 2n is transmitted directly to the cylinder mounting / dismounting apparatus without using multiplex transmission. Transmission delay is eliminated, and information transmission to the body attaching / detaching device conventionally took about 0.1 second to about 0.000.
Less than 1 second.
【0027】そのため、全ての印刷装置において最も時
間余裕を持たせた状態で指令信号を出すことができ、印
刷胴の着脱を安定して作動させることができる。Therefore, the command signal can be issued in a state in which all the printing apparatuses have the longest time allowance, and the attachment and detachment of the printing cylinder can be operated stably.
【0028】従って、多重伝送の利点を保持しながら、
安定して印刷胴着脱を作動させることができ、配線数の
少ない、損紙が少ない機械を提供することができる効果
がある。Thus, while retaining the advantages of multiplex transmission,
It is possible to provide a machine capable of stably operating the attachment and detachment of the printing cylinder and having a small number of wires and a small number of waste papers.
