Description

[Detailed Description of the Invention] This invention relates to a binding device that overlaps and binds a plurality of continuous forms.

Conventionally, a thermocompression bonding device 1 shown in a sectional view in FIG.
The continuous form 2 that has been folded or cut into two sheets is transported by a transport tractor 3, and the continuous form 2 is
The sheets are passed through a hot platen 4 that provides adhesive conditions for the heat-sensitive adhesive previously applied to the binding portion of the overlapping surfaces of the sheet, and are pressed together with pressure rollers 5 to create a bound document.

However, this device does not require the use of pressure-sensitive adhesives to stitch together multiple continuous forms, such as overlapping two or more continuous forms with separate top and bottom sheets. If the pressure of the pressure roller is strong, when the continuous forms are rolled up by the pressure roller, the continuous forms above and below and the continuous forms stacked on the inside become misaligned, and the continuous forms on the inside are pushed out by the pressure roller. Although the deviations were small, they accumulated and caused wrinkles in the bound forms.

Taking these points into consideration, this design is suitable for stitching together more than two consecutive forms, and a pressure-sensitive adhesive that does not adhere under normal conditions is pre-applied to the stitching area. It is an object of the present invention to provide a binding device that can easily create bound documents with an excellent appearance without causing wrinkles even when applying strong pressure from a pressure roller as a bonding condition to a plurality of continuous documents. do.

Next, this invention will be explained based on the drawings showing this invention.

Figure 2 shows a plurality of continuous forms P ₁ , P ₂ , P ₃ , which are used to create a bound form by stitching the sides of a plurality of sheets together.
It is an explanatory diagram of _P4 . Each of these continuous forms P ₁ , P ₂ ,
Transfer holes 10 are provided on both sides of P ₃ and P ₄ , and a binding section 11 is located at a predetermined position inside the left transfer hole 10 , and the back side of continuous forms P ₁ , P ₂ , P ₃ is continuous Each binding section 1 on the front side of forms P ₂ , P ₃ , and P ₄
1, a pressure-sensitive adhesive 12 that does not adhere under normal conditions is applied in a linear manner.

Figure 3 shows a binding device 20 related to this invention.
is a cross-sectional explanatory view of the binding device 20, in which the binding device 20 connects the guide plate 21 and the continuous documents _P1 , _P2 , _P3 , _P4 along the flow direction of the continuous documents _P1 , _P2 , _P3 , P4. A stacking tractor 22 and a pressure roller 23 are sequentially provided for superimposing and transporting ₄ , and the pressure roller 23 has a smaller pressure area than the pressure roller 23 and protrudes at predetermined intervals on the circumference of the roller. It is constructed by providing a point pressure roller 24 that performs point bonding.

Further, around the pressure roller 23, an overlapping tractor 22 and a notch 25 are provided to smoothly eliminate transfer errors that occur when the pressure roller 23 transfers the material. Further, 26 and 26 are receiving rollers, which are cylindrical in this embodiment, but are a point pressure roller 24 and a pressure roller 2, respectively.
It may be a roller having the same form as No. 3.

To explain this idea when creating a bound document using the above-mentioned binding device 20, first, the ends of each continuous document P ₁ , P ₂ , P ₃ , P ₄ are aligned and the transfer holes 10 are overlapped. When the sheets are set on the stacking tractor 22 and the binding operation is started, the successive continuous forms P ₁ , P ₂ , P ₃ , P ₄ are superimposed and transported along the guide plate 21 and the stacking tractor 22, and then they are transferred to a point. When reaching the pressure roller 24, the binding portions 11 of each continuous form P ₁ , P ₂ , P ₃ , P ₄ are bonded at predetermined intervals. At this point, each continuous form P ₁ , P ₂ , P ₃ , P ₄ is placed on the point pressure roller 2.
4, pressure is applied at points during transfer, so the upper and lower continuous forms P ₁ and P ₄ and the inner continuous form
There are no wrinkles between P ₂ and P ₃ , and there is virtually no shift in the transfer, and they are further transferred to the pressure roller 2.
However, each continuous form P ₁ ,
P ₂ , P ₃ , and P ₄ are bonded at predetermined intervals, and the pressure roller 23 connects the upper and lower continuous forms P ₁ ,
The accumulation due to the slight distortion that attempts to cause a transfer gap between P ₄ and the inner continuous forms P ₂ and P ₃ is the continuous form P ₁ ,
Since P ₂ , P ₃ , and P ₄ are eliminated between the portions that are point-glued at predetermined intervals, it is possible to create a bound document that does not suffer from wrinkles due to transportation misalignment.

In addition, in an example of the thermocompression bonding method in which a thermothermal adhesive that does not adhere to the continuous form under normal conditions is used, vertically opposing heating plates are installed between the overlapping tractor and the point pressure roller. Alternatively, if a pressure-sensitive adhesive is used, a point pressure roller can be provided on or just in front of the tractor.

As described above, according to this invention, with a simple configuration in which a point pressure roller is provided in front of a pressure roller, it is possible to create a good-looking bound form that does not cause misalignment or wrinkles even when there are more than two continuous forms. have an effect.
