BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stacker bundler that accumulates and presses a signature discharged from a printing press such as an offset rotary press into a certain number of bundles and binds by bending. .

A stacker bundler according to the related art will be described with reference to FIGS. 9 to 14. Generally, as shown in FIG. 9, the conventional stacker bundler 1 includes press rollers 2 and 2 ', a conveying apparatus 3, a flow splitting apparatus 4, a bending roller (reinforcement roller or the like). (5,5 '), an integrated device for accumulating small batches (hereinafter referred to as "small batch accumulator") (6), and a fabrication unit for producing large batches (hereinafter referred to as "bulk mass"). 7), press apparatus 8, and the like. The conveying apparatus 3 is provided with the conveyance belt 3a of a string form. As the flow splitting apparatus 4, for example, the present applicant has disclosed in Japanese Unexamined Utility Model Publication No. 5179 filed in Japan.

The peak 9 discharged from the web press (printer) not shown in the drawing enters the press roller 2, and the convex portion of the peak bag is pressed and static electricity is removed. The peak 9 which emerged from the press roller 2 is conveyed in the state overlapped horizontally by the conveying apparatus 3, and is bent rollers 5 and 5 'near the exit of the conveying apparatus 3 (FIG. 10). By giving a so-called "waist" (hereinafter referred to as "prosthesis") due to the center of the width direction being bent into a mountain shape or a wave shape, and then discharging or discharging therefrom. It falls, and is integrated in the small batch accumulator 6.

The small batch apparatus 6 works together with the shear peripheral regulating member 10 and the shear peripheral regulating member 10 for stopping the shear peripheral portion of the peak 9 flowing out from the bending imparting rollers 5 and 5 '. The rear end peripheral restricting member 11 for aligning with the front and rear lengths of the peaks 9 to be integrated is disposed opposite. The trailing edge regulating member 11 is composed of a bending belt 5 and a regulating belt 11a wound around the pulley 11b, and the regulating belt 11a is in frictional contact with the trailing edge of the apex 9. The pinnacle 9 is rotated to force it downward.

In addition, the small batch accumulator 6 guides both sides of the peak 9 to be integrated, and the pair of guide plates 73 and the temporary receiving plate 14 for aligning the position of the peak 9 in the width direction. It is provided. As shown in FIG. 13, the guide plate 73 is divided into an upper plate 73a and a lower plate 73b through the slit 75, and the upper plate 73a and the lower plate 73b have a horseshoe shape in cross section. It is connected by a connecting member 81 formed as. In addition, the guide plate 73 can be adjusted to the left and right facing intervals in accordance with the width of the peak (9).

The temporary receiving plate 14 is configured to be freely moved back and forth with respect to the slit 75 of the guide plate 73 by the cylinder 83, and is climaxed at the temporary receiving position entered into the slit 75 shown in FIG. Temporarily accept 9). In this way, the slit 75 into which the temporary receiving plate 14 can enter is formed in the guide plate 73, and the guide plate 73 adjusts the gap between the left and right sides within the width range of the temporary receiving plate 14. It is possible to respond to the vertices 9 of various widths. One guide plate 73 and the shear peripheral restriction member 10 vibrate little by little, and align the peaks to be integrated.

When a certain number of peaks pass through the conveying device 3 and accumulate in the small batch aggregator 6, the flow splitting device 4 is activated, temporarily blocking the flow of heat in the peak 9. And a gap is formed in the flow of heat of the peak 9. In the meantime, the lifting platform 13 of the small quantity accumulation device 6 which loaded the small quantity of the peak 9 descends (FIG. 9 shows a lowering position), and pushes the small amount on the platform 13 (15). To the mass production unit (7).

The flow splitting device 4 is deactivated before the platform 13 rises, so that the subsequent flow of the peak 9 is made by advancing the temporary receiving plate 14 into the small batch accumulator 6. When the platform 13 is returned to a predetermined lift position (see FIG. 11), the temporary receiving plate 14 moves backward, and the peak bunch accumulated in the temporary receiving plate 14 is moved onto the platform 13 and accumulated. do.

The mass production unit 7 receives and accumulates a small mass of the peak 9 accumulated in the small mass accumulation apparatus 6 to produce a mass mass of the peak. The paper sheet is fed into a sheet, pressed by the press apparatus 8, and then bound. In the mass production unit (7), if necessary, the fold line of the peak (9) is piled up in several layers by rotating a small amount of counterclockwise so that the small line is the opposite position.

However, in the conventional stacker bundler, the shear edges of the integrated peaks are deformed in the small batch integration device. MEANS TO SOLVE THE PROBLEM As a result of researching the cause of this deformation | transformation, it discovered that it originates in the phenomenon as described below. That is, the peak 9 discharged from the bending imparting rollers 5 and 5 'and dropped into the small batch accumulator 6 falls as if the front is slightly lowered as shown by the virtual line in FIG. The peak to which the "prosthetic part" in which the width direction center part was made mountain shape by the bending rollers 5 and 5 'is a peak which becomes a "prosthetic part" when it sees on a planar surface as shown in FIG. The vertex of the shape falls to the shape which protrudes forward. Therefore, when the peak discharged from the bending imparting rollers 5, 5 'is stopped by the shear circumference regulating member 10, the apex 9a of the culmination 9 is first applied to the shear circumference regulating member 10. It collides and the vicinity of the apex is deformed.

In addition, as shown in Fig. 14, when the temporary receiving plate 14 comes out of the temporary receiving position and the small batch is transferred to the platform 13, the slit 75 is opened, so that the climax 9 is opened. Entering the slit 75 and protruding to the outside of the guide plate 73 occurs, there is a problem that can not accurately fit the peak (9). To solve this, for example, insert the brush into the slit with the brush side down, and when the temporary receptacle enters, the brush of the brush is bent, and after exiting, the brush of the brush returns to the straight state. A method of preventing protrusion of the climax by preventing the slit has been proposed. However, when the brush of the brush is deformed and does not return to its original form, the climax may protrude and the entry of the slit may not be secured. In addition, there is also a problem that the brush must be frequently replaced and maintenance costs are high.
