Abstract

PURPOSE:To improve the discharge by forming the guide in a discharger for discharging a folded book having predetermined pages movably in parallel and angular adjustably while adapting to the variation of the book size. CONSTITUTION:A folded book 6 is dropped onto a conveyor 8 and discharged while sliding the tip portion along the guide face 7a of a guide board 7 by means of a paper drop tape 5. Here the guide board 7 is moved in parallel through bevel gears 24, 27 as shown by dashed line by rotating a regulating shaft 22 through a handle, while when rotating a handle 29 the angle is regulated through a joint 16 and a fixed shaft 10 as shown by the dashed line to be positioned in correspondence to the size of the folding book 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharging device for a folding machine of a rotary printing press, and particularly to a discharging device used in a folding machine in which the size of signatures can be arbitrarily changed.

In conventional devices of this kind, when the documents discharged from the folding drum are dropped onto the conveyor via the impeller, the guide plate used to discharge the documents to a certain position on the conveyor is fixed or fixed. One that rotates in position has been implemented.

For this reason, so-called "Pual Folding Machines" which allow the size of signatures to be arbitrarily selected cannot adjust the position of the guide plate in response to changes in the size of signatures.

The present invention eliminates the above-mentioned drawbacks, and provides a discharge device for a folding machine of a rotary printing press having a guide plate adjustment device suitable for a multiple pull folding machine. It is characterized by being provided with a device for adjusting the angle.

Embodiments of the present invention will be explained below with reference to FIGS. 1 and 2, which show embodiments of the present invention.

FIG. 1 is a front view showing a discharge device in a folding machine of a rotary printing press according to the present invention, and FIG. 2 is a plan view showing a guide plate drive device thereof. In the figure, reference numeral 1 denotes a folding drum, which moves a signature 6 folded into a predetermined number of pages at the same speed as the folding drum 1, facing one part of its outer peripheral surface when rotated in the direction of the arrow. The signature 6 is peeled off from the outer circumferential surface of the folding cylinder 1 at the tip of a paper/paper guide 3 inserted and fixed between the folding drum 1 and the tape 2 and dropped onto the impeller 4 below.

Then, using the paper drop tape 5, the leading end of the signature 6 is slid on the guide surface 7a of the guide plate 7 and dropped to a fixed position on the conveyor 8 below.

I'm sleeping. The conveyor 8 is suspended between two foils 8a and moves in the horizontal direction so as to discharge the signatures 6 dropped from the impeller 4 at regular intervals.

The guide plate driving device according to the present invention has the configuration described below.

10 is a fixed shaft, and both ends are attached to the frame 1 of the rotary press body.
It is fixedly supported by two brackets 12 fixed to the inner surface of the housing.

Reference numeral 13 indicates two fixed levers, each having an upper end fixedly supported by the fixed shaft 10, and a lower end rotatably supporting a joint 14.

Reference numeral 15 is two hinge levers, the upper end of which is rotatably supported by the fixed shaft 10, and a joint 1 at the lower part of one end surface at a position diagonally above the joint 14 of the fixed lever 13.
6 is rotatably supported, and a joint 17 is provided at the center of the other end surface.
is rotatably supported, and a rail 18 having a cross section of ] is fixed to the lower part thereof so that it is in a horizontal state when the two hinge levers 15 are in the position shown in FIG.

Reference numeral 19 is a guide support bar having a cross-section of [3], the guide plate 7 is fixed on one end vertically, a nut 20 is fixed on the upper end flat surface, and a nut 20 is fixed on the upper end plane, and a guide support bar 19 is provided on both ends so as to be slidable in the rail 18. Two supported rollers 21 are rotatably supported. The nut 20c is positioned so as to be horizontal with respect to the joint 17 of the hinge lever 15 when the hinge lever 15 is in the position shown in FIG.

Reference numeral 22 is an adjustment shaft, a handle 23 is fixed to one end at a position outside the frame 11, two bevel gears 24 are fixed to an inner position of the frame 11, and one end of 26 is rotated. It can be inserted freely.

The first threaded shaft 26 is rotatably supported at the joint 17 of the hinge lever 16, and has a shoulder end fixedly supporting a bevel gear 27 that meshes with the bevel gear 24, and the other end screwed into the guide support bar. It is screwed into the nut 20 of 19.

28 is a second screw shaft, which is rotatably supported at the joint 14 of the fixed lever 13, and has a handle 2 at one end.
9 is fixed, and the other end threaded portion is screwed into the joint 16 of the hinge lever 15.

With the above configuration, the guide drive device has the handle 2.
3 rotates, the adjustment shaft 22 rotates, and the two sets of bevel gears 2
4.27, the first screw shaft 26 rotates. Further, when the handle 29 is rotated, the hinge lever 15 and the guide plate 7 are rotated about the fixed shaft 10 through the joint 16, and the internal focus of the guide plate 7 is adjusted as shown in the attachment.

Therefore, polishing the guide drive device of the present invention is easy.

In response to changes in the size of the signatures 6 falling from the impeller 4 onto the conveyor 8, one or both of the two inner handles 23 or 29" or at the same time The position of the guide plate 7 can be easily adjusted by rotating it.
