Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a stacker device that stacks sheets of paper or sheets of paper that are stacked and processed into sheets that are discharged in parallel from a discharge port.

2. Description of the Related Art Conventionally, a stacker device is attached to a sheet-fed printing machine, an office processing device, etc., and used to stack a large amount of discharged paper. In recent years,
As printing and office processing become faster, various paper stacks with a large capacity have been developed.
Additionally, in order to increase the speed of printing and office processing, attempts have been made to simultaneously print and process multiple sheets in parallel.

Problems to be Solved by the Invention However, when multiple sheets of paper or pieces of paper stacked and processed into sheets are received and stacked in parallel from the output outlet of a printing machine, office processing device, etc., as shown in Figure 6. The side edges 51 of adjacent sheets of paper P discharged from the discharge port 50 overlap,
When a large amount of paper is piled up, it takes a lot of effort to separate them. In addition, the edges of the overlapping sheets are piled up to form a mountain shape, causing problems such as sheets to be stacked later slipping and becoming unable to be stacked any further.

The object of this invention is to provide a paper stacker device that eliminates these drawbacks.

Means for Solving the Problems The stacker device according to this invention includes a stacker table on which the paper discharged from the stacker table is placed, a transport mechanism that transports the paper on the stacker table, and a stacker table that transports the paper on the stacker table. A deflection guide is arranged in parallel at the top and facing the paper discharge port with a gap therebetween, and has a deflection piece that guides the leading edge of the paper sheets discharged in parallel from the discharge port to the stacker table for each paper sheet. At the same time, the deflection guide for the paper located on the outer side with respect to the center of multiple papers ejected in parallel is wider on the outer side than on the center side in the distance from the paper ejection port to the paper contacting part of this deflection guide. It is oriented diagonally so that

Function When paper is ejected in parallel from the ejection port, the deflection guide of the paper located on the outer side with respect to the center of the plurality of sheets ejected in parallel will reach the paper contacting part of the deflection guide from the paper ejection port. At a distance of occurs. Therefore, since the stacking angle of the sheets on the stacker table can be controlled, the rear sides of the sheets that are discharged in parallel from the discharge port can be spread outward, so that the sides of the sheets do not overlap each other. This allows them to be stacked one after another on a stacker table in a stable manner.

Embodiments This invention will be described below based on drawings showing examples of the invention.

FIG. 2 is a side cross-sectional explanatory view showing the state in which the stacker device 1 of this invention is attached to the cutting device 20 for continuous paper 21. The paper 21 will be explained based on FIG. 3. The continuous paper 21 is constructed in a two-wide format in which unit forms A and B are arranged in parallel, and are continuous with a perforation 22 as a boundary. Marginal portions 24 having transfer pinholes 23 are provided on both sides of the continuous paper 21, and are printed in parallel to column A and column B of the unit form of the continuous paper 21 by a computer.

After the printing process, as shown in FIG.
placed on top. The continuous paper 21 is fed into a feed tractor 30 having a pin that engages with a pinhole 23 via a rising guide 28 and a feed 29 . Then, the marginal portion of the continuous paper 21 provided with the pinhole 23 is cut off by the tractor slitter 31a, 31b, and the continuous paper 21
A slitter 31c that slits the center in a continuous direction.
is adapted to be driven and rotated by the same drive shaft as the tractor slitters 31a and 31b. The continuous sheets 21 divided into two unit form columns A and B are guided in parallel by a circulating transfer guide belt 32 and sent to a pair of upper and lower low-speed rolls 35a and 35b.

Further, the continuous paper 21 is rotated from the former low-speed rolls 35a, 35b configured to have the same feed amount as the feed amount of the feed tractor 30. The rotation speed of these rolls 35a, 35b, 36a,
Tension is generated due to the difference in rotational speed of 36b, and tension is applied to the perforation 22. Then, at this perforation 22, the first low speed rolls 35a, 35b
A blade 37 provided next is brought into contact with the continuous paper 21 to tear the unit forms A and B of the continuous paper 21 in parallel. The cut unit forms A and B pass through the belt feeder 38 in parallel and are discharged from the discharge port 39 of the belt feeder 38 to the stacker device 1.

The unit forms A and B discharged in parallel from the discharge port 39 are deflected by the rider disk 5 serving as a deflection guide and stacked one after another on the stacker table 4, but the unit documents A and B are discharged from the rider disks 5 ₁ and 5 ₄ on both sides. Central rider disk protruding from the side 5 ₂ ,
5 ₃ , the rider disks 5 ₁ , 5 ₂ and the rider disks 5 ₃ , 5 ₄ are diagonally opposed to the outside with respect to the paper, and due to the difference in deflection timing for guiding the paper to the stacker table 4, The rear sides of the unit forms A and B are turned outward, and are separated from each other as a whole and placed on the stacker table 4 and transported.

Although the sheets to be ejected in parallel are shown as two columns of unit forms A and B in this embodiment, there is no problem even if the sheets are ejected in three columns of unit forms C, D, and E. . In that case, as shown in the fourth figure, six rider disks 5 serving as deflection guides are attached, and the center rider disks 5' ₂ , 5' ₃ ,
5' ₄ , 5' ₅ to both side rider disks 5' ₁ , 5' ₆
It is only necessary to protrude toward the discharge port side relative to the discharge port.

In other words, the rider disks 5' ₁ and 5' ₂ and the rider disks 5' ₅ and 5' ₆ of the sheets located on the outside with respect to the center of a plurality of sheets that are discharged in parallel are placed on the sheets respectively. They may be set so that they face outward and face diagonally.

Further, the deflection guide does not necessarily have to be a rider disk, but may be a plate-shaped deflection piece 41 having a deflection surface 40, as shown in FIG.
Regarding the means for protruding the central deflection piece relatively toward the discharge port side compared to the outer deflection piece, the plate-shaped deflection piece 4 is also used.
1 may be installed at a different mounting position, or the deflection ratio of the deflection surface 40' of the central deflection piece 41' may be made larger than that of the outer deflection piece 41'.

Effects of the Invention As is clear from the above explanation, the stacker device of this invention has a plurality of deflection guides that face the paper ejection port at intervals and guide the leading edge of the paper onto the stacker table. are provided in parallel, and the deflection guide for the paper located on the outside with respect to the center of the plurality of papers discharged in parallel is located on the center side in the distance from the paper ejection port to the paper contacting part of this deflection guide. Since the paper is oriented diagonally so that the outer side is wider, when the paper that is ejected in parallel hits the deflection guide, the trailing edges of the paper transported by the transport mechanism will overlap due to the difference in deflection timing. The sheets are separated and stacked on a stacker table with a certain distance between them, and a large amount of paper is transported in that state and separated for each transport row, and processed by printing machines, office processing equipment, etc. Even when multiple sheets are ejected in parallel, the sheets next to each other do not overlap and can be processed smoothly, making it extremely effective in improving the efficiency of office work. be.
