Abstract

PURPOSE:To enable to perform an efficient work to arrange in a good order a number of papers, by a method wherein a number of the papers are longitudinally superposed with each other and are supported, the papers are conveyed on the conveying end side as air is injected against the papers to separate them from each other, and the edges of the papers are trued up. CONSTITUTION:When a number of piles-up papers fed to a printer are arranged in good order, a first table plate 1 is firstly vertically erected as shown by a chain line, and a number of the papers vertically piled up are placed on a press nip plate 7 positioned down. After the table plate 1 is turned over to a horizontal orientation shown by a solid line, the press nip plate 7 is moved rightward as plural feeding-out device 10, such as belt conveyors, mounted in the direction of width to the right end part of the table plate 1, and an air injecting mechanism 11, located between the devices 10, are operated. This causes the papers to be separated at the right end part of the table plate 1 so that they are prevented from being superposed each other, and are conveyed onto a second table plate 12, and in which case, the front end part in the direction of conveyance is supported by a movable support press plate 13 and is guided rightward.

Description

[Detailed Description of the Invention] During printing operations in a printing factory, many sheets of piled paper are fed to the paper feeding mechanism of a printing machine, and the end faces on the feeding side are not perfectly aligned. If this occurs, there is a risk that smooth paper feeding may not be obtained or the printing position may shift. Especially for additional printing (additional colors, multicolor printing), etc.
If you need to run the same paper twice or three times through a printing machine, or if you want to print on both sides, collect the required amount of printed paper and place it on the loading surface. If the edges on the feeding side of the paper are not aligned perfectly, it is difficult to reprint or print in the specified position.Therefore, conventional paper alignment methods have been used manually, but this is inefficient and can damage the paper itself if the paper is thin. The disadvantages were that the paper was not stiff, the papers tended to stick together, and it was difficult to get the paper straight.

Therefore, the present invention provides a paper alignment method for mechanically aligning a large number of sheets of paper without such drawbacks, and a +i! : It insults Nao by saying that it is a sacrifice for everyone.

One of the present inventions is to collect a pile of prized papers,
The stacked paper is supported by vgH with its overlapping direction turned sideways, and the stacked paper is transferred from one end side to the other end, and air is injected to the paper at this transfer end side. Invented a method for aligning paper using a camphor tree, which involves sequentially feeding and transporting paper while maintaining separation, and aligning the transported paper.9
, Another invention is an invention of an apparatus directly used for carrying out the invention of the method described above, which is capable of freely inverting and returning from an upright direction in which a stack of sheets of paper is placed horizontally to a horizontal direction. The paper placement surface of the first plate can be moved and returned freely in the perpendicular direction, and the feeding mechanism and air injection mechanism are placed in positions facing the three clamping columns of the first plate, and the paper is placed horizontally. When the first base plate is reversed in the direction, the second base plate, which is located parallel and horizontal to the first υ plate on the extending side where the clamping support is provided, can be freely reversed in the upright direction as necessary. A paper support plate is provided on the paper loading surface of the second base plate to which the FA6 ejecting mechanism can be transferred, and the paper support plate can be freely moved in the longitudinal direction of the plywood.

Next, embodiments of the present invention will be described with reference to the drawings.

When f(11) is operated #dJ, the paper on the side of the clamping column of the stacked paper standing upright on the first base plate is subjected to a feeding action and at the same time due to the air jet. The sheets of paper that are fed out and transported are separated and transported one after another without overlapping each other. In this case, If on the first base plate
The paper pattern paper is pinched at both ends by a clamping support, and the paper is fed out between the supports in an arched state, and the overlap between the papers is also peeled off at the same time. If the pressing and holding plates are moved in accordance with the amount of reduced paper, paper can be fed out and transferred without any inconvenience.

When the first base plate is reversed in the horizontal direction, a second base plate is arranged horizontally parallel to this on the feed-out side where the clamping support is provided, and the second base plate is fed out and transferred from the first base plate. The paper is sequentially transferred onto two boards. In this case, the paper support press plate (13) provided on the paper placement surface (12a) of the second base plate
