Abstract

PURPOSE:To perform the coating with a size and the bonding of a cover to the back of a book, by constituting a clamper so as to make the same freely revolvable upwardly between a position where the cover of a book body is bonded and a position where the book body is inclined from a horizontal state and revolving the same to turn the back of the book body toward a diagonally upward direction. CONSTITUTION:When a clamper 4 is raised by required power or manual operation, the clamper 4 is revolved around a shaft by an arm 11. By this revolution, the back B of a book body A is gradually turned upwardly. In this revolving process, the clamper 4 is further revolved by an arm 12 through a shaft 9 to promote the upward turning of the back B performed when the clamper 4 is revolved only by the arm 11. A cover D is placed on the surface of a nipper clamp plate 3 and a size is applied to the back B automatically or manually. The clamper 4 is reversely revolved to be returned to the initial position. The back B is pressed to the cover D from above and the cover D is bonded by the coated size. The nipper clamp plate 3 is loosened and the clamper 4 is revolved upwardly and the clamper tightening plate 5 of the clamper 4 is loosened to take out the book body A having the cover D bonded thereto.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a bookbinding device.

(Prior Art) As is well known, in bookbinding, glue is applied to the spine of the book to be bound, and then a cover is pasted thereon.

In conventional bookbinding equipment, the cover is attached on the surface of the base by first aligning the spines of each book.

This is clamped with a clamper, and then the clamper is moved horizontally, and glue is applied to the back during the movement.

After that, return the clamper to the position for attaching the first cover, lower the clamper here, or raise the base to press the first cover against the spine and attach it, and at the same time tighten it from both sides with nippers to form it. That's what I do.

(Problems to be Solved by the Invention) According to the conventional bookbinding apparatus described above, the position for attaching the cover of one book and the position for applying glue are separate locations arranged horizontally, so both positions must be secured. This has the disadvantage that a space is required for this purpose, resulting in an increase in the size of the device.

The object of the present invention is to enable applying glue to the spine of a book and attaching a cover using a small device.

(Means for Solving the Problems) In this invention, the cover of the main body is attached so that it can freely pivot upward between the position where the cover of the main body is attached and the position where the main body is tilted more than horizontally, and by this turning, the cover of the main body is attached. It is characterized in that the back is directed at least diagonally upward.

(Function) The main body is held vertically and the cover is clamped at the clamper position. The clamper is then pivoted upward, and the pivot tilts the main body above horizontal.

This inclination causes the back to face diagonally upward, so glue is applied manually or automatically at that position. After that, the clamper turns again and returns to its original position. In the meantime, if the cover is set in the position for attaching the cover, the spine will approach the cover from above.

If the spine attaches to the cover by this approach, the cover becomes attached to the spine. At this time, press nippers against the back to shape the back.

Thereafter, the clamper is rotated again, the clamper is opened at the rotated position, and the book is pulled out from the clamper, thereby completing the series of bookbinding operations.

When attaching a cover, the glue application position is located above, so there is no need to line up both positions horizontally as in the past. Therefore, the space required for bookbinding can be reduced.

(Example) An example of the present invention will be described with reference to the drawings. 1 is the base frame, 2
3 is a pair of nipper clamping plates for forming the spine B of the main body A, which can be slid in opposite directions along the surface of the base 2; 4 is a clamper, which is slidable in opposite directions to each other along the surface of the base 2; It is movable and includes a pair of clamper clamping plates 5 for tightening the main body A, a knob 6 for moving the clamper clamping plates 5, and the like.

According to this invention, the clamper 4 can be freely pivoted upward from the cover sticking position.

The turning mechanisms 8 are provided on both sides of the main body A, and each turning mechanism 8 is constructed as follows.

That is, 9 and 10 are shafts supported at fixed positions on the base frame 1, and both of these are perpendicular to the top (or bottom) surface C of the main body A. 11°12 has one end connected to each shaft 9,
10, and the other end is attached to the side plate 7 of the clamper 4 with shafts 13, 14.
It is an arm connected by.

Therefore, the axis 9 is above the axis 10, and the axis 1 is above the axis 10.
The distance between the axes 9 and 14 is shortened compared to the distance between 0.13 and 0.13.

The cover of the Naori Lamba 4 is attached in a position where the main body A is perpendicular to the base 2 and the spine B of the main body A is in contact with the surface of the base 2 (see Figure 2 A). , the line connecting the axes 10 and 13 and the line connecting the axes 9 and 14 are parallel to each other.

Reference numeral 16 denotes a drive mechanism for sliding the nipper clamping plate 3 as described above, which includes a motor shaft 17, a chain 18 driven by the motor shaft 17, a drive shaft 19, 20 of the nipper clamping plate 3,
The gears 21 and 22 are fixed to each drive shaft and driven by a chain 18.

As the motor shaft 17 rotates, the chain 18,
The drive shafts 19 and 20 rotate in opposite directions through the gears 21, 2, 2, and thereby the nipper clamping plates 3 slide in opposite directions to tighten or loosen the main body A.

Next, the effect will be explained. As shown in Figure 2A, the clamper 4
is moved to the position for attaching the cover, and here the main body A is put into the clamper 4 and tightened. At this time, the back B of the main body A is the base 2
is in contact with the surface of

Then, the clamper 4 is lifted by the required power or manually. Then, the clamper 4 is rotated by the arm 11 about the axis 1o. By this rotation, the back B of the main body A
gradually begins to move upward.

During this turning process, the clamper 4 is connected to the arm 1 via the shaft 9.
2 further turns. By this turning, when the clamper 4 is turned only by the arm 11, the upward movement of the back B is promoted, and the back B rapidly moves upward.

As a result, even if the turning angle of the arm 11 does not become very large, the back B can be sufficiently turned upward. In other words, the back B is turned over at a position near the front of the base 2 (this is also the position of the operator). FIG. 2B shows this state. Note that FIG. 1 shows the state in which the clamper 4 is in the process of reaching the position shown in FIG. 2B.

A cover sheet is placed on the surface of the nipper clamping plate 3 at the position shown in FIG. 2B, and glue is applied to the spine B automatically or manually. Back B
Since it is almost right in front of the operator, the work is extremely easy.

Next, the clamper 4 is rotated in the opposite direction to return to its original position. By this return, the spine B is pressed onto the cover paper, and the cover paper is pasted with the previously applied glue. At this time, the nipper clamping plate 3 slides toward the main body A, tightens it, and performs the required forming. This state is shown in FIG. 2C.

In addition, at the end of this return, when the spine B approaches the cover edge, the line connecting the axes 10 and 13 and the line connecting the axes 9 and 14 become parallel. Since the clamper 4 and therefore the body A descend almost perpendicularly to the surface of the base 2.

As a result, when the spine B is pasted to the cover sheet, there will be no misalignment between the two, and the spine B will be pasted neatly.

After the spine B and the cover are firmly attached, the nipper clamping plate 3 is loosened and the clamper 4 is turned upward again. Then, at the pivoted position, the clamper clamping plate 5 of the clamper 4 is loosened, and the main body A with the cover sticker pasted is taken out.
