Description

[Detailed explanation of the invention] This invention is a method of continuously gluing the overlapped surfaces of continuous sheets of paper to create cards, postcards, etc.
The present invention relates to a continuous paper processing device having a continuous paper folding and bonding device for creating stacked adhesive sheets such as ledgers and envelopes.

Conventionally, when stacking continuous sheets of paper and gluing the stacked surfaces together, adhesive was applied by placing a roller holding adhesive against one stacked surface, or by applying a wettable adhesive to the stacking surface in advance. A water-containing roller was brought into contact with the adhesive-coated surface of continuous paper coated with adhesive to apply moisture, and the paper was then stacked and bonded.

However, with these methods, adjusting the adhesive and moisture is complicated and difficult to handle.Especially when applying the adhesive and moisture, the paper stretches and becomes soft, making it difficult to fold it from a specified position, and wrinkles may occur. However, it was not possible to obtain a stable product.

Therefore, in this invention, when bonding the overlapping surfaces of continuous paper for stacking, the elongation of the continuous paper is kept to a minimum, and adhesive liquid is applied to every corner of the stacking surface under stable folding. can supply
Furthermore, the present invention provides a continuous paper folding and gluing device that can be easily handled as an office device.

Next, an explanation will be given based on drawings showing an embodiment of this invention.

Fig. 1 has transfer holes 3 along both end sides in the continuous longitudinal direction, perforations 4 that serve as boundaries between unit sheets 2 at predetermined intervals, and wettability on the back side that becomes the folded and overlapping surface. A continuous paper folding and gluing device suitable for producing cards, postcards, ledgers, envelopes, etc. from a continuous paper 1 coated with an adhesive 8 and provided with a folding perforation 5 in the center along the continuous longitudinal direction is provided. Continuous paper processing device 1 connected to the previous stage
0, this device folds the continuous paper 1 into two in the continuous longitudinal direction, and connects the folded and glued unit paper 2 to the continuous paper 1 with the folding adhesive section 20 that applies adhesive conditions to the folded and overlapping surfaces. It consists of a cutting section 30 for cutting from.

As shown in FIG. 2, the above-mentioned folding adhesive part 20 has tension members 21, 21 at the bottom and squeeze members 22, 22 at the top, and is located between the tension members 21, 21 and the squeeze members 22, 22. A jetting nozzle 23 is provided, and a jetting receiving plate 24 is provided opposite to the jetting nozzle 23 to cover the back, side, and lower part of the continuous paper transport path.

In front of the lower tension members 21, 21, a paper tray 26 is installed which has a paper drawer guide member 25 that facilitates pulling out the folded continuous paper.

The paper drawer guide member 25 is also provided with sensing means such as a micro switch 27 for sensing the presence or absence of continuous paper. It constitutes a stop mechanism that stops the continuous paper 1 when the end of the continuous paper 1 reaches the jet nozzle 23 according to the signal detected from the micro switch 27.
The mound is adjusted so that it stops when it passes in front of the.

The cutting section 30 connected to the folding adhesive section 20 is provided at the rear of the tractor 32, which has a feed guide plate 31 that facilitates the introduction of the continuous paper 1 and a pin that engages with the transport hole 3 of the continuous paper 1. A pair of low speed rollers 33 and a pair of high speed rollers 3
4, tension is applied to the perforation 4 of the continuous paper 1 by the speed difference between these rollers 33 and 34, and the part of the perforation 4 is brought into contact with the blade 35 provided between these rollers, and the continuous paper is 1
The structure is such that the unit paper 2 is torn from the paper.

A tank 37 and a pump 38 for supplying water to be jetted from the jetting nozzle are built into the lower housing of the cutting section, and a tractor 32 for transporting continuous paper, driving each roller and turning on the jetting nozzle is also built in. , a control mechanism for controlling OFF is also built in, and the unit paper at the end is carried out from the high speed rollers 34, 34 by the sensing of the micro switch 27 or other sensing means 39 installed in front of the cutting section 30. Each roller is configured to be driven and then stopped.

Note that the squeezing members 22, 22 provided on the folding adhesive section 20 are composed of two rollers or bars, and are provided diagonally so that the folded section of the continuous paper 1 can be clamped first. Further, an auxiliary shaft 29 is provided on the lower side of the folded portion of the continuous paper 1 to press down the lower folded portion to prevent unnecessary wrinkles from forming. Reference numeral 36 denotes a transfer table for the cut stacked adhesive paper 6.

Next, to explain the operating state of the continuous paper processing device in the embodiment of this invention, necessary information is printed on each unit paper 2 by a printer, which is an output device of an electronic computing device, and the continuous paper 1 folded in a zigzag manner is printed. Place the continuous paper 1 on the paper tray 26, hang it on the upper paper drawer guide member 25 so that it can be easily pulled out, pass it through the tension members 21, 21, fold it in half and sandwich it between the upper squeeze members 22, 22. The feeding guide member 31
The continuous paper transport hole 3 is set on the pin of the tractor 32 on the cutting section side via the cutting section.

After setting the continuous paper 1 in this way, if this device is driven, the continuous paper 1 will be pulled up one by one from the lower tension members 21, 21 to the upper squeezing members 22, 22 by the tractor 32, and on the way, the continuous paper 1 will be pulled up by the jet nozzle 23. , mist water is sprayed onto the folded and overlapping surface 7. At this time, water and the like splashed on areas other than the folded and overlapping surfaces are collected by the jet receiving plate 24.

And in the upper squeeze members 22, 22,
The auxiliary shaft 29 pushes up the lower part of the folded part of the continuous paper 1, clamps the continuous paper 1 from the folded part side to the opposite side while preventing the occurrence of wrinkles, and glues the overlapped surfaces while sequentially folding.
Cutting section 30 via feeding guide plate 31 and tractor 32
send to Then, the stacked and glued continuous paper 1 is cut at the perforation 4 by the low-speed rollers 33, 33, the blade 35, and the high-speed rollers 34, 34, and becomes the stacked adhesive paper 6 consisting of the unit sheets 2, and is carried out to the transfer table. be done.

When the adhesion work continues and the continuous paper runs out, the micro switch 27 provided on the paper drawer guide member 25 detects that the continuous paper runs out, and when the spray nozzle finishes spraying the final end of the continuous paper, At the same time, the spraying is stopped, and then the final end passes another sensing means 39, and when the final end passes the high speed rollers 34, 34, the tractor 32, low speed rollers 33, 33, high speed roller 3
4, 34, etc. are stopped.

Note that the micro switch 27 does not need to be provided at the paper drawer guide member 25, but may be provided on the tension member 21, and may be provided in front of the jet nozzle so that the end of the continuous paper 1 can be easily detected. That's fine.

In addition, in the above, the wet adhesive 8 is on the back side.
Although the continuous paper 1 coated with is used, a continuous paper 1 coated with no wettable adhesive 8 may be used, and in that case, a liquid adhesive may be used instead of the water to be jetted.

As described above, since this device has the above-mentioned structure and function, compared to the conventional continuous paper folding and gluing device, since the adhesive liquid is sprayed onto the continuous paper, the elongation of the continuous paper is reduced. Even if the continuous paper runs out, the adhesive liquid will not be accidentally splashed, and even if the liquid is scattered by jetting, it will not unnecessarily stick to areas other than necessary, making it extremely easy to handle. It is possible to obtain a continuous paper processing device provided with a simple continuous paper folding and gluing device.
