Abstract

PURPOSE:To enable a correct raising and aligning work of a printed paper group by continuously transporting a printed paper group under a laying condition, and raising and aligning the papers with a stacker in sequence, wherein the lower face of each paper is supported by a transport belt while the upper face is guided forwards with a driving and retaining belt. CONSTITUTION:In raising and aligning a printed paper group A sequentially at a raising part T of a stacker S, the group A is guided actively by a lower delivery roller O and a part of a transport belt D, or the vertical central part of the group A is for example guided forwards actively in the middle part of a fixed retaining guide plate H. Thereby it is possible to form the group in an arc shape to have a strong stiffness facilitating the raising and aligning work of the group A. The lower part of each paper rides onto a transport belt F by the aid of the delivery roller O through a delivery guide P which facilitates, with its friction, the alingning of the lower part of printed paper group A' raised and aligned and the transport thereof to the belt F.

Description

Detailed Description of the Invention: "Industrial Application Field" The present invention is designed to sequentially stand up a group of sheets of paper sheets, which are wrapped at a partial pitch and are in a sleeping state, which are continuously transferred from a rotary press, at a rising part of a stacker. The present invention relates to a method and an apparatus for aligning a group of printed books in which the group of printed books is aligned and sequentially moved forward.

``Conventional technology'' Conventionally, in order to align a group of printed books one after another on the rising section of a stacker, a holding guide plate was fixedly provided at the rising section of the stacker to hold down the upper surfaces of the group of printed books and align them. Only.

"Problems to be Solved by the Invention" With such conventional products, it is difficult to ensure that each copy of a group of copies is aligned, and especially if one copy is made of thin paper, thin pages, or paper. It was difficult to reliably stock items that were not flexible or had large print sizes.

In many cases, the sheets would buckle or become erect in the middle, making it difficult to form bundles of printed books later on, which would hinder post-processes such as packing and binding of printed books.

This is because, as mentioned above, the holding guide bullet is merely fixedly provided on the upper surface of the book group at the rising portion of the book group.

``Means for Solving the Problems'' The present invention provides a method for sequentially arranging a group of printed books that are continuously transferred from a rotary press on a part of a stacker using a transfer belt. A part of the transfer belt and the conveyor belt interfere with each other to move them forward, and at the same time, the upper surfaces of the group of copies are held down by a presser guide plate to align them, and at the same time, they are held down by a drive presser belt to actively guide them forward. This is a method of arranging a group of prints in such a way that a roller for feeding out the group of prints and a conveyor belt are provided at the bottom, and a drive holding belt is provided at the top to actively move the upper surface of the group of prints. Furthermore, it is a device for aligning a group of printed books, which includes a fixed presser guide plate and a drive presser belt arranged side by side.

Furthermore, a crossing guide plate is provided between the feed roller and the conveyor belt, and the friction generated by this crossing guide plate makes it easy to line up the group of printed books.
In addition, the speed of the driving presser belt is increased in synchronization with the conveyor belt to form a group of printed books in an arcuate shape to improve their alignment, and furthermore, the drive presser belt is installed in parallel between the presser guide plates on both sides. It is something.

``Function'' When a group of printed books is lined up one after another on the rising part of the stacker, the group of printed sheets is actively guided by the upper drive holding belt, the lower feeding roller, and a part of the transfer belt, and also, for example, By actively guiding the upper and lower center portions of the group of prints forward in the middle of the fixed holding guide plate, the prints can be formed into a bow shape, creating a waist in the prints and making it easier to align them. . Further, the lower part is transferred onto the conveyor belt via the feeding roller and the transfer guide, and the friction of this transfer guide also improves the alignment of the lower part of the group of prints and the transfer to the conveyor belt.

"Example" An apparatus for carrying out the method of the invention will be described with reference to the drawings.

A is transferred from a rotary press (not shown) to the rising section T of the stacker S in a state where it has been continuously lapped at a partial pitch (each copy is shifted and overlapped). A group of printed books is coming, B is its feeding belt, C is a transfer belt that successively receives the above-mentioned group of printed books A, and is raised and conveyed. D is a counter transfer belt that faces the raised transfer belt C, and is conveyed to the drum J. A set of printed books is sandwiched between the conveyor belt C and the conveyor belt C, and A' shows a group of printed books that are raised up and lined up by the opposite conveyor belt D. Raise the counter transfer belt D with the ringing fork I (the one shown in Fig. 2 is the bookend fork K).
The group of printed books A' held between the two is sent forward, and the group of printed books A' is bound by a band at a binding portion (not shown).

Reference numeral 0 denotes a feed-out roller in contact with the rising opposing transfer belt D, and a crossing guide P is provided between the feed-out roller 0 and the conveyor belt F.

The crossing guide P uses its friction to facilitate the alignment of the group of printed books A'. Further, a part of the transfer belt C is wound around the feed roller 0.

H is a fixed presser guide plate that presses the top surface of the book group A. A drive presser belt G is provided between the presser guide plates H and H on both sides, and the drive presser belt G and presser guide plate H stand up. Align the tops of the raised booklet group A''.

As shown in FIG. 2, the drive holding belt G is moved by the rotation of the rotating shaft G' driven by the drive chain L.
It comes into contact with the upper surface of the group of printed books A' and guides it forward. Note that the belt G may be a pressure roller Q.

The drive presser belt G increases the speed of the conveyor belt F and moves in synchronization with the feed roller O, a part of the transfer belt C wound around it, and the drive presser belt G to move the upper and lower parts of the print group A''. is sent out faster than the running speed of the conveyor belt F. In addition, in the present invention, the upper and lower center portions of the group of prints A' may be fed out at high speed, and the group of prints A' may be formed into an arcuate shape to improve alignment. This provision produces the effect that the contact pressure between the lifting belt D and the book group A' becomes constant.

Note that M represents a holding guide block, and N represents a screw for moving the holding guide block M up and down.

The group A of prints rises one after another at the rising portion T, and between the feeding roller O, the presser guide plate H, and the drive presser belt G, the upper parts of the group A' of prints are aligned, and the group A' is lined up one after another and crosses through the guide plate P. conveyor belt F
is sent forward.

Further, in the present invention, a part of the transfer belt C may be wound around a freely rotating roller that is coaxial and has the same diameter as the winding roller R of the conveyor belt F (dotted line). Further, a part of the transfer belt C may be wound around a freely rotating roller S with a large diameter coaxial with the winding roller R (dotted line portion). The roller S is provided only at the center of the booklet group A' in the width direction.

4゜Effect: In the present invention, the upper surface of the group of printed books is actively guided forward by the drive holding belt at the rising part of the stacker, so that the printed sheets are formed into an arched shape, creating a waist in the printed sheets. It becomes easy to set up. The provision of the driving presser belt also has the effect that the contact pressure between the raising belt and the group of printed books is constant, and alignment can be performed accurately. Furthermore, since a crossing guide is provided between the feeding roller and the conveyor belt at the lower part of the group of printed books, the friction with this crossing guide improves the alignment of the lower part of the group of printed books and the transfer to the conveying belt.

Therefore, in the present invention, the alignment of the set of prints, which is an important point in forming a bundle of prints of a certain number of copies, can be done extremely easily and accurately, and the prints can be printed evenly, from thick paper to thin paper, and from thick pages to thin pages. , even slippery printed books can be aligned with sufficient accuracy.
