Description

[Detailed description of the invention] The present invention cools rotary paper after printing in a rotary printing machine, and also performs perforation, hole punching, and
The present invention relates to a post-processing device that performs embossing, streaking, slitting, number printing, and the like.

In recent years, with the remarkable development of offset rotary printing presses, it has become possible to obtain high-quality printed matter that is almost similar to that produced by sheet-fed offset printing presses. Multi-color commercial printed matter, which had previously been printed, began to be printed using offset rotary presses.

In addition, with the spread of computers, computers have come to be used to process addresses for direct mail and the like.

Therefore, conventional rotary printing presses have been equipped with a folding machine for publications, but recently there has been a demand for machines that are connected to the above-mentioned post-processing and post-printing devices such as number printing. There is an increasing demand for a dedicated machine of this type and a multi-purpose machine that is combined with a conventional folding machine or a zigzag folding machine for form printing.

Offset rotary printing presses are generally equipped with a paper feeding device, a printing device, a drying device, and a cooling device, and these devices are arranged in series along the direction of rotation of the rotary paper, so they require a long installation space. ,
In such a rotary printing press, if the above-mentioned post-processing device or post-printing device such as a number printer is installed behind the cooling device, there is a problem that the installation space described above becomes even longer.
Another drawback is that the range of movement of the operator is long and the operability is poor.

The present invention was developed in view of the above points, and it is possible to selectively incorporate post-processing devices such as perforation processing and post-printing devices such as number printers into the cooling device as appropriate, thereby improving post-processing. The present invention provides a post-processing device for a rotary printing press in which a post-processing device or a post-printing device can be installed without increasing the space of the rotary printing press or reducing operability.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is a cooling device for a rotary printing press, and this cooling device 1 includes three cooling rollers 2 through which cooling water is passed, a direction changing roller 3,
The rotary paper 5 is heated and dried in the drying device, is cooled by passing around each of the cooling rollers 2, and is discharged to the rear via the direction change roller 3. It is becoming more and more common. An attachment mounting portion 6 is provided at the upper rear side of the frame 4 of the cooling device 1, that is, at the upper portion on the downstream side in the direction in which the rotary paper 5 travels. Reference numeral 7 designates a number printer which is removably attached to this attachment mounting portion 6 as an attachment, 8 is an impression cylinder, 9 is a plate cylinder, and 10 is an inking device. A frame 11 supports both ends of each cylinder and roller, and this frame 11 is fixed to the attachment mounting portion 6 with bolts 12.

Figure 2 and the following diagrams show other attachments that can be attached to the attachment attachment part 6 of the cooling device 1. 13 is a hole punching device (Figure 2), 14 is a horizontal perforation device (Figure 3), and 15 is a simple A perforation device, 16 is an embossing/scoring device, and 17 is a slitting/vertical perforation device.

The above-mentioned attachments are selected according to the post-processing specifications of the rotary-printed rotary paper and are attached to the attachment mounting portion 6 provided on the frame 4 of the cooling device 1. After passing through the cooling device 1, the rotary paper 5 is passed through these attachments to undergo post-processing such as drilling and horizontal perforations.

The attachment mounting portion 6 is provided at the upper part of the downstream side of the frame 4, so that the lower side of the frame 4 of the cooling device 1 has sufficient strength, and is constructed by cutting out a part of the frame 4.

The present invention has been described in detail above, and includes a cooling device 1 having a frame 4 with an attachment attachment portion 6 provided at the upper part of the downstream side in the running direction of the rotary paper 5, and a cooling device 1 which is detachably attached to the attachment attachment portion 6. number printer 7, hole punching device 13,
Since the post-processing device of the rotary printing press is composed of attachments such as the horizontal perforation device 14, the simple perforation device 15, and the embossing/scoring device 16, etc., by selectively incorporating the above-mentioned attachments into the cooling device 1. , a post-processing device or a post-printing device can be installed without increasing the space required for a rotary printing press. Also, as mentioned above, since there is no increase in space, the range of movement of workers can also be reduced.
By installing the post-processing device, it is possible to prevent a decrease in operability without making the process particularly long.
