Description

Stacker bundler}

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. .

Hereinafter, a conventional stacker bundler 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 shape 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 in a mountain shape or 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. The guide plate 73 and the shear peripheral regulation member 10 on one side vibrate little by little, and align the peaks accumulated.

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 amount of the peaks 9 accumulated in the small amount accumulator 6 to produce a mass mass of peaks. When a predetermined number of copies is reached, the mass bundles are transported to the binding unit and the upper and lower sides of the bundles are reached. The sheet of paper 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 in planar view 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 part facing down and when the temporary receptacle enters, the brush of the brush is pressed and bent, and after exiting, the brush of the brush returns to the straight state. A method of preventing the climax from protruding by blocking 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.

Accordingly, the present invention has been made to solve the above problems, in the small batch integrated device, a stack capable of correctly accumulating the peak without eliminating the deformation of the peak or a part of the peak is not neatly arranged.

Hereinafter, a first embodiment of a stacker bundler according to the present invention will be described with reference to FIGS. 1 to 3B.

The stacker bundler of the first embodiment has the same reference numerals as the shear peripheral restricting member of the small batch integration device and the compressed air injection nozzle described below, which are different from the conventional ones, and the other configurations are the same as the conventional ones. Omit. 1 is a perspective view showing a shear peripheral limiting member of a small batch integrated device, Figure 2 is a cross-sectional view taken along the line A-A of FIG.

As shown in FIG. 1, the shear peripheral restricting member 10 is composed of a comb-tooth shaped member having a plurality of teeth 20 extending in the vertical direction, as shown in FIG. The row of teeth 20 is the center of the row at the forefront when viewed in a plan view corresponding to the peak shape of the signature formed by the bending rollers 5 and 5 '. It is arranged in a curved shape. That is, the curved shape of the shear circumference of the peak 9 when it is discharged from the bending imparting rollers 5 and 5 'and collides with the shear circumference regulating member 10 corresponds to the arrangement of the teeth 20.

By arranging the rows of the teeth 20 in such a curved shape, the shear circumference of the apex 9 collides almost evenly with respect to each tooth 20 of the shear circumference regulating member 10, so as to "waist". Only the apex front portion of the following (hereinafter referred to as the "prosthesis") is prevented from first colliding and deforming. In addition, the width | variety of each tooth part 20 does not need to be equal, for example, may be made to expand only the width | variety of the tooth arrange | positioned in the center, etc.

Each of the teeth 20 is independently assembled so as to be able to adjust in and out of the front-back direction, and it is preferable that the arrangement of the teeth 20 can be adjusted. In the drawing, a long hole 22 extending in the front-rear direction is formed in the support bar 21 supporting the tooth 20, and the tooth 20 is fixed by the bolt 23 passing through the long hole 22. In addition, the lower surface of the support bar 21 is formed with a groove 24 extending in the front and rear direction, the teeth 20 are formed in a cross-sectional rectangle, the teeth 20 as the teeth 20 are coupled to the grooves 24. ) Is prevented from rotating in the axial direction.

The teeth 20 ', 20' disposed at both ends in the width direction of the front end peripheral regulating member 10 are disposed at the longitudinal direction position of the climax 9 on the basis of the position of the rear end peripheral regulating member 11. The peak integrated in the small batch accumulator 6 by this arrangement is regulated by the front teeth 20 ', 20', and the rear is regulated by the trailing edge restricting member 11. In addition, the shear circumferential limiting member 10 is subjected to a vibration which swings only a predetermined angle forward from the vertical position with the support bar 21 as the center of rotation.

As shown in FIGS. 3A and 3B, the bending roller 5 has four peripheral grooves 5a formed therein, and compressed air nozzles 30 are inserted in the peripheral grooves 5a. have. This compressed air nozzle 30 is arranged so that the compressed air injected from the nozzle is directed in the direction along the flow at the bottom of the flow of the peak 9 discharged from the bending rollers 5, 5 ′. The peaks 9 discharged from the bending rollers 5 and 5 'are discharged in a staggered state, but by injecting air between the overlapping peaks up and down, a space is forcibly formed between the overlapping portions of the top and bottom edges, and the top and bottom sides of the top and bottom sides are discharged. Eliminate close clutter and accumulate small batches of staggered gaps.

The compressed air nozzle 30 is controlled by a control device, not shown in the drawing, so that the flow rate of air increases while the peak stopped by the flow splitter 4 is discharged from the bending rollers 5, 5 '. It is preferable to be. While stopped by the flow splitting apparatus 4, the staggered density of the peaks 9 becomes high. In other words, as the degree of staggering of the peaks decreases, the contact areas of the staggered overlapping peaks increase, thereby increasing the electrostatic attraction. As a result, the force required to release the overlapping peaks up and down by blowing the compressed air from the compressed air nozzle 30 increases, thereby increasing the air flow rate of the compressed air according to the increase. In this way, the space can be formed between the peaks having a high density by being overlapped by the flow splitting apparatus 4, and a small amount of neat small gaps can be accumulated.

Next, a second embodiment of a stacker bundler according to the present invention will be described with reference to FIGS. 4 to 8B.
