Description

[Detailed description of the invention] This invention is a folding machine for letterpress, gravure, and rotary offset printing machines in which an adjustment guide roller is arranged after a part of the nipping roller to register the printed paper in the flow direction, that is, to align the bottom of the lines. Relating to an adjustment device.

Conventionally, the new registration guide roller installed in rotary printing presses has the function of vertically registering the printing paper in the direction of travel, which is continuously folded in the center by the folding machine triangular plate located above the roller. Registration in the flow direction, that is, alignment of the bottom of the lines, was performed by adjusting the nose position of the triangular plate.

However, due to the slight change in the nose position due to the adjustment of the nose of the triangular plate during high-speed rotation, it is easy to cause folding defects, and there is a risk of paper waste due to adjustment errors. It took a long time.

The present invention was devised to solve such problems, and makes it extremely easy to align the bottom of the lines of printed paper in a folding machine.

That is, a folding machine that is disposed after a part of the nipping roller of a rotary printing press folding machine, is supported by a frame, and has a guide roller that rotates in a fixed manner, and a roller shaft on one side that is supported on the frame, and the roller shaft on the other side that is movable. This folding machine adjusting device is characterized in that it aligns printing paper folded and conveyed from a triangular plate in the flow direction by finely adjusting an adjustment guide roller.

The present invention will be explained according to the drawings.

FIG. 1 shows the folding machine section of a rotary printing press in which the device 3 of the present invention is installed, in which a frame 14 includes an adjustment guide roller 8 that supports a roller shaft on one side and makes the roller shaft on the other side movable; A guide roller 9, which is supported by the frame 14 horizontally to the roller 8 and rotates fixedly, is installed parallel to a part of the nipping roller of the triangular plate folding machine, and the moving axis side of the adjustment guide roller 8 is finely adjusted horizontally. This folding machine adjusting device is characterized by aligning the short folds of the printed paper 7 that is folded and discharged from two triangular plates passed through guide rollers 8 and 9 separately. After passing through each nipping roller 2, the two rows of printing paper 7 folded at the center by the triangular plate 1 of the present invention are aligned with the triangular plate fold sides by the device 3 of the present invention, so that the bottom of the ruled line is aligned and merged into the folding body 4.
It is folded to 5.6 degrees and transported.

FIG. 2 is a detailed explanatory diagram of the device 3 of the present invention.

The peripheral end of the shaft of the fixed guide roller 9 and the one-side roller shaft support portion 12 of the guide roller 8 for aligning the bottom of the ruled line are connected to the frame 1.
It is fixed at 4.

Both ends of the fixed guide roller 9 and the day/night setting guide roller 8 are rotatably supported by bearings 13.

By turning the adjustment dial 10, the movable bracket 11 at one end of the guide roller 8 for day/night adjustment is moved, changing the parallelism between the adjustment guide roller 8 and the fixed guide roller 9, thereby conveying the material between each guide roller. The daytime of the printed paper 7 can be adjusted.

As described above, after the printed paper folded and conveyed from the triangular plate folding machine of the rotary printing press passes through each nipping roller and is aligned in the direction of travel, the folding machine adjustment device of the present invention adjusts the daytime and the vertical register. It is possible to match the daytime of the printing paper by finely adjusting the guide roller for daytime/daytime adjustment, and there is no need to adjust the nose position of the triangular plate as in the past, reducing paper waste and making adjustments easier. This saves time and prevents work hazards due to daytime adjustments.
