Abstract

PURPOSE:To make the paper discharge mechanism of folding machine quite compact by arranging a paper discharge belt at the lower section of impeller to be perpendicular against the feeding direction of folded book between the folding drum and impeller. CONSTITUTION:The folded book completed of cutting and folding through folding drum group, cutter drum, plunge drum and biting drum 9 is fed through a carry tape 13 to an impeller 4 if the deflector lever 2 is in upper position then the position is limited by a fixed stopper 11 and a paper guide 12 to be fallen onto the paper discharge belt 6. If said lever 2 is in lowr position, it is fed through the carry tape 13 over the impeller 3 and fallen onto the paper discharge belt 5. Thereafter, it is discharged in two rows through paper discharge belts 5, 6 in perpendicular direction against the feeding direction of folded book through folding drum group and contained in rear stage stacker.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paper discharge mechanism in a folding machine of a printing press.

[Background of the invention]

A rotary press with a structure in which a long length of printed paper is pulled out from a roll, and after the specified printing process is performed in the printing section, the printed paper is completely cut, folded, and then discharged by a rotating impeller and a paper discharge belt. The printing machine has a built-in automatic folding machine. The present invention relates to the configuration of a folding machine of this type of printing press, and is intended to reduce the size and compactness of the conventionally large-sized folding machine.

Figures 1 and 2 show the typical configuration of a folding machine used in a conventional rotary printing press of this type. .4 is an impeller, 5 and 6 are paper discharge belts, 7 is a cutter body, 8 is a thrust side, and 9 is a clothes removal side. In the folding machine having the configuration as shown in the figure, the printed paper 1 is cut by a cutter cylinder 7, the folded signature is conveyed through a thrusting side 8, a cloth removing part 9, and a third The distributed portion shown in the figure is distributed by a lever 2 to an impeller 3.4 arranged above and below the paper to be delivered to discharge belts 5 and 6, and then discharged. In other words, the distribution of the signatures discharged from the folding drum group depends on the vertical movement position of the lever 2, and the distribution of the signatures is determined by the lever. By the vertical movement of 2, it is possible to divide the amount into two stages, upper and lower. The signatures discharged in this manner fall onto paper discharge belts 5, 6 (by the rotating impellers 3, 4) and are conveyed to a stacker device (not shown).

According to the same configuration, after folding the printing paper, at the paper ejection section.

Since the paper is sent to a transport mechanism arranged in two stages (upper and lower), either the folding machine part for sending it to the transport mechanism arranged in two stages has a large structure, or the stacker device in the latter stage has a large structure as well. It was something like that.

[Purpose of the invention]

The present invention has been made in view of the problems in the prior art described above, and it is an object of the present invention to reduce the size of the entire printing press by making the folding section smaller.

[Summary of the invention]

In order to solve the above-mentioned problems, the present invention has a mechanism that distributes the cutting, main folding, and leaving portions by a folding drum into upper and lower portions.
The paper guide is used to regulate the signatures sent to the conveyance mechanism and impeller.

The signature is dropped onto a discharge belt placed perpendicular to the signature, and the signature is sent to a subsequent stacker after changing its delivery direction to the perpendicular direction.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 4 to 6. 4 and 5 correspond to the above-described FIGS. 1 and 2, and those having the same reference numerals have the same functions.

Moreover, FIG. 6 is a schematic enlarged view of FIG. 5.

As shown in these figures, the major difference from the conventional structure is that the paper ejection belts 5 and 6 are arranged in a direction perpendicular to the direction in which the folding cylinders advance the signatures. Note that 10 is a stacker for storing the signatures conveyed by the paper discharge belts 5 and 6, and 11 and 12 are fixed stoppers and paper guides installed on the sides of the impellers 3 and 4.

According to the same configuration, the signatures that have been cut and folded by the folding drum group, the cutter drum 7, the plunger side 8, and the copper removal 9 are as follows:
First, when the lever 2 is in the upper position, as shown in the enlarged view of FIG. The position of the paper is regulated and the paper is dropped onto the paper discharge belt 6. Further, when the lever 2 is positioned downward, the distributed portion is caused to fall on the conveying tape 13 via the impeller 3 and onto the paper ejection belt 5.

Furthermore, when the lever 2 moves up and down for each fold, the folds are alternately dropped onto the paper discharge belts 5 and 6. The signatures which have been lowered by kg onto the paper ejection belts 5, 6 in this way are conveyed by the paper ejection belts 5, 6 with a force of 10, but the paper ejection belts 5, 6 are moved by the folding drum group. Since the signatures are arranged perpendicularly to the sending direction of the paper, the signatures are ejected in two rows in the perpendicular direction and stored in the stacker 10 at the subsequent stage.

According to the same configuration, the paper ejection belts 5 and 6 are placed on the same plane.
Since the folding section is arranged at right angles to the signature sending direction, the folding section can be made extremely compact, and the stacker can also be made smaller. Also, since a paper guide is attached to the part where the paper falls to the paper ejection belt, paper alignment is improved.

〔Effect of the invention〕

As is clear from the above-described embodiments, according to the present invention, the paper ejection belt that delivers the signatures to the stacker is configured to be able to deliver the signatures in a direction perpendicular to the direction in which the signatures are delivered by the group of folding cylinders. Because of this, the paper ejection mechanism of the folding machine is extremely compact, and the stacker is also compact.
The printing press has the advantage of requiring less space to install.
