JPS6337050A - Device for inserting thin paper into pamphlet - Google Patents

Abstract

PURPOSE:To laborsave the operations and improve the productivity by opening the pages of a book one by one and inserting therebetween each leaf sheet supplied from another sheet feeder. CONSTITUTION:Two large and small rollers 3 and 4 are installed in an upper and of pamphlets or sheets of thin paper 2 stacked on an inclined surface plate 1. One end of the large roller 3 is nicked or fitted with a clip. When a vacuum suction hole 5 attracts the pamphlet or the thin paper 2 and goes down and simultaneously the large roller 3 gets moving in an arrow direction, the upper end of the pamphlet or the thin paper 2 is easily held between the large roller 3 and the small roller 4, and travels on a conveyor tray 7. When a pamphlet conveying lever 8 conveys the pamphlet up to a position of a page opening device and is stopped there, a page opening vacuum suction hole 9 performs its reciprocating motion, opening a page of the pamphlet. If the thin paper 2 has been inserted between the specified pages, the page is closed on the con veyor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for inserting paper into a booklet such as a book, magazine, pamphlet, or problem book created during a bookbinding process.

Traditionally, the work of inserting blank sheets such as errata, answer sheets, and notices on the back cover or inside the pages of books, magazines, pamphlets, problem sets, etc. that have been collated has relied heavily on manual labor. I had no choice.

However, this manual work is quite difficult and tiring for the operator when the number of printed matter is large, in the hundreds of thousands.

Therefore, it was impossible to imagine how much it would contribute to labor savings and productivity improvement if this work could be done using the power of mechanical equipment.

The present invention is a device made to solve this problem, and will now be specifically explained with reference to the drawings.

Figure 1 is a process explanatory diagram showing the arrangement of this device. When the booklets are fed one by one onto the conveyor from the book feeder on the right side and reach the page opening device, they are opened one page by the vacuum suction hole. When the machine reaches the next flat paper supply device, a sheet of flat paper to be inserted is supplied. If the third page is the one to be fed, the first and third paper feeders will not operate, and the first, third, and third page opening devices will not operate. turns over three pages of the booklet, and then the third paper feeder operates to feed the third paper to be inserted.

Thus, the booklet moved from right to left on the conveyor is
At the final position, the pages are automatically closed and collected by the booklet stacking device.

Figure 2 is a schematic cross-sectional view of the main parts showing the function of this device.Two large and one small rollers are placed on the upper edge of the booklets or paper sheets (2) stacked on the inclined surface plate (1). +31F
41 will be provided.

Use a large roller (3) with a notch at one end, or use one with a clip to hold the paper.

Therefore, when the vacuum suction hole (5) sucks the upper end of the booklet or paper (2) and descends, the large roller (3) begins to move in the direction of the arrow.
The upper end of the large roller (3) and the small roller 5-
(Iζ on the conveyor tray (7) sandwiched between 41
Moving.

If at this time, the double feed prevention claw (6) is activated by the action of the cam to prevent the booklet or paper (2) from being sucked twice.
It is necessary to provide

The conveyor tray (7) has a booklet conveying lever (8), which can convey one booklet at a regular interval.

The booklet transport lever (8) on the conveyor tray (7) may be operated continuously, but intermittent motion is preferred in order for the page opening vacuum suction hole (9) to open the pages.

When the booklet conveying lever (8) carries the booklet to the position of the page opening device and stops, the page opening vacuum suction hole (9) performs a reciprocating movement to open the pages of the booklet.

In order to ensure that the pages are opened one part at a time, a double opening prevention claw 0α and a fixing suction hole (Ill) for fixing the booklet on the conveyor tray (7) from the back surface using a vacuum are provided.

In this way, once a piece of paper is inserted between the predetermined pages, the page is closed on the conveyor, but it is best to partially deform the shape of the conveyor tray so that the paper can pass through it. You can close the pages of the booklet in order.

Finally, the booklets whose pages have been closed are counted by an accumulating device and at the same time are divided into fixed numbers of books such as 10, 50, and 100 by the action of an optical switch, a counting counter, and an electromagnet.

General 1: When inserting paper into a booklet, there are many pages where the front cover is close to the back cover.

Therefore, the page opening device only needs to be capable of handling 1 to 5 pages.

For devices that work like this machine, it is convenient to have a mechanical device with a unit type structure that can be increased or decreased depending on the scale of use.

As described above, by using the uninvented mechanical device, the work that had previously been done by sea entry operations can now be done accurately and quickly, and the efficiency of printing and bookbinding work has significantly improved.
