Abstract

PROBLEM TO BE SOLVED: To form a lateral sewing line in the specified position of a continuos paper sheet from the beginning by reading a position of register marks provided on the continuous paper sheet at specified distances and operating a position adjusting device according to the error between the machining estimated position to be determined according to the position and the position of a machining member. SOLUTION: The positions of register marks M provided on a continuos paper sheet P at the specified distances are read by a reading sensor. Simultaneously, the position of a machining member of a machining device is read by a machining position reading device. The machining estimated position L1 is calculated from a position signal of the read register mark M, and a machining position L2 is calculated from the position of the machining member. After that, the machining estimated position L1 and the machining position L2 are compared with each other. Therefore, when it is judged that the machining estimated position L1 is positioned on the upstream side from the machining position L2 in the feeding direction A of the continuos paper sheet P by the error E, the position adjusting device is operated, and the machining position L2 can be made to coincide with the machining estimated position L1.

2. Description of the Related Art In a continuous rotary printing press, it is necessary to perform registration or the like at the start of printing or at a change in speed. However, in recent years, in an ink jet printing rotary press for printing variable information, which has begun to be widely used, loss printing for registration or the like has a possibility that the first part of the variable information becomes loss printing. Since it is large, it can be said that the tolerance of loss printing is extremely small.

[0003] Registration of continuous paper in an ink-jet printing rotary press having extremely low tolerance for loss printing has been performed by a competition device for changing the traveling distance of continuous paper fed continuously. . On the other hand, ink jet printing presses generally use water-based ink for printing, and therefore, the printed ink is dried using a large-sized drying device, or the running distance of continuous paper is set longer to dry. Needed. For this reason, the continuous paper greatly expands and contracts due to a change in the tension during the drying process or the operation, and the actual situation is that the registration by the competition device has not been fully supported.

And an arithmetic and control unit 5 for operating the position adjusting device 4 so as to adjust the position of the processing member 2a of the processing device 2 by the corrected amount.

As shown in FIGS. 2 and 3, the processing apparatus 2 includes a processing cylinder 2A having a processing member 2a mounted on an outer peripheral edge thereof.
And the receiving cylinder 2B. As the processing device 2,
A processing device such as a conventional sewing device or a file punching device can be employed. In the case of the sewing machine, the processing member 2a is a sewing blade mounted on the outer peripheral edge of the processing cylinder 2A, and in the case of the file punching apparatus, the processing member 2a is a punch mounted on the outer peripheral edge of the processing cylinder 2A. The processing device body 2 is rotated by a servomotor 6. The servo motor 6 is a position adjusting device 4
The processing cylinder 2A (and the receiving cylinder 2B) can be rotated forward or backward by a rotation angle corresponding to a required correction amount by a control signal from the arithmetic and control unit 5.

The reading sensor 1 can be any sensor capable of sensing the passage of a register mark M printed on a continuously fed continuous paper P and generating an electrical position signal. For example, a phototransistor arranged close to the continuous paper P can be used. Similarly, the processing position reading device 3 is also capable of reading the position of the processing member 2a in the circumferential direction of the processing cylinder 2A and generating any electrical or mechanical position signal. For example, an electric and / or electronic reading device can be applied. For example, a plurality of slits are formed in a radial direction, and a disk is mounted on the rotating shaft of the processing cylinder 2A, and a light emitting diode and a phototransistor are provided on both sides of the disk. Can also be used.

The arithmetic and control unit 5 receives a signal from the reading sensor 1 and receives a signal from the register mark M at a predetermined processing distance L1 at a predetermined interval to reach a processing position L2 by the processing member 2a of the processing apparatus 2, The time when the position of the processing member 2a read by the processing position reading device 3 reaches the processing position L2 is calculated, and the position adjusting device 4 (this embodiment) is set so that the error E between the two becomes substantially zero.

The register device of the present invention configured as described above reads the position of the register mark M provided at a predetermined interval on the fed continuous paper P by the reading sensor 1, and at the same time, reads the processing position. The position of the processing member 2a of the processing device is read by the device 3. The read position signals are sent to the arithmetic and control unit 5, where the processing position L1 is calculated from the position signal of the register mark M, and the processing position L2 is calculated from the position of the processing member 2a.

Is not limited, and can theoretically be corrected for an error E of infinite length, and at least registration by a conventional competing device (the distance between a pair of In this case, the allowable amount of correction is mechanically limited due to the expansion and contraction of the elastic member.
