Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper alignment mechanism for a bookbinding apparatus using adhesive.

In a bookbinding device using adhesive, a heated roll comes into contact with the back of the bound work, and the molten adhesive adheres to the surface of the roll.

Therefore, aligning the adhesive surfaces of the bound material is an essential requirement to eliminate defective spines of the bound material and improve the quality of the binding.

However, when the bound material becomes thick, it is not easy to align the adhesive surfaces, which causes a decrease in the binding strength or a defective spine.

In order to overcome this drawback, there is a conventional bookbinding device that is equipped with a mechanism that automatically vibrates the bound workpiece after it is set in a predetermined position, but it is expensive to install such a mechanism.・Although it may be adopted in high-end machines, it is currently not possible to introduce it in popular machines, although it is necessary.

OBJECTS OF THE INVENTION The present invention relates to an improvement of a bookbinding device devised in view of the above-mentioned points. We provide a bookbinding device equipped with an inexpensive paper alignment H structure that can eliminate defects.

By disposing a support plate to support the regular surface, supporting the support plate so as to be tiltable along the opening/closing direction of the bound product, and providing a holding means for holding the support plate 1ffY in an arbitrary tilted posture.
With the support plate in an inclined state, stack the bound products little by little to align the adhesive surfaces of the bound products.

EXAMPLE Hereinafter, an example of the present invention (1) illustrated in FIGS. 1 to 9 will be described.

1 is a bookbinding device, and the bookbinding device 1 includes a book platen 3 on which the adhesive surface of the bound object 2 is placed, a support plate 6 that supports the side surface of the bound object 2, and a holding device that maintains the inclined posture of the support plate 6. 9
And clamp the bound product 2 with the hook clamp 14 and apply glue to the bound product 2 with the glue roll 1
It consists of 9 mag.

The hook platen 3 is formed to have a predetermined length Cf] in the longitudinal direction and the width direction of the bound product 2, and a rack 4 is formed at the -1 end of the hook platen 3. The pinion 4 is disposed on its immediate side and is engaged with a pinion 5, so that the book platen 3 can be moved up and down by rotation of the pinion 50.

Further, as shown in FIGS. 1 to 3, the temporary support 6 is the same support piece 6a formed with a predetermined length and height in the longitudinal direction of the bound product 2. Support piece 6b and support piece 61a facing 6a at a predetermined interval

A compression fill spring 13 is interposed between 1 and 1.

However, drum 10. Plagin-'--4. ．． The I, No; -f portion 4412 and the compression coil spring 13 constitute a holding device 9 for the support plate 6, which allows the support plate 6 to tilt and maintains the tilted posture of the support plate 6 so that it can float around. It has become. That is, the compression coil spring 13 between the 12th guide part 4 and the brake shoe 11 has a relatively strong biasing force, and this biasing force presses the brake shoe 11 against the drum 10 with a predetermined pressing force\drum 10 and applying a predetermined frictional force to the player shoe,
The drum 10 is held at the desired position, and as a result, the support 6 is held at an arbitrary inclined position and is floating while maintaining this inclined posture. Also, when tilting the support plate 6, if the operating lever 7 is pushed forward, there is a frictional force between the drum 10 and the brake shoe 11, but the frictional force is such that there is no need to operate it. The support plate 6 is designed so that it can be tilted and tilted.

The hook clamp I4 is slidably supported on the side piece 6C of the support plate 6 as shown in FIGS. 1 and 2. The book clamp 14 and the support piece 6a of the support plate 6 stand so that the bound book 2 can be clamped. In other words, the cam iPH+ 15a is attached to the side piece 6C of the support plate 6 to rotate in an oval shape, and the cam ipH+ 15a is mounted biased to one side with respect to the cam 15, so that the cam 15 can clamp the book. 14 stroke ■ can be taken largely.
