Description

[Detailed Description of the Invention] The present invention involves cutting and crimping continuous forms coated with pressure-sensitive adhesive on their overlapping surfaces while transporting them, thereby continuously sealing sealed documents. The present invention relates to a pressure-bonding, overlapping and stitching form creation device that creates a form by overlapping and stitching together materials such as the like.

Conventionally, in this type of press-bonding overlapping stitching form creation device, the overlapping surface has 1i! After cutting the continuous form coated with pressure-sensitive adhesive into unit forms, the forms are bound by applying a predetermined pressure, which is the bonding condition for the pressure-sensitive adhesive, when passing between appropriate pairs of upper and lower pressure rollers. We are making adjustments. Generally, one of the upper and lower pressure rollers is pressed against the other by the elastic force of a spring.

However, with the configuration in which the upper and lower pressure rollers are pressed against each other by the elastic force of a spring, depending on the thickness of the unit form, it may not be possible to pass smoothly or an unnecessarily strong pressure may be applied. However, there are disadvantages in that the bonding of the foam is difficult and the foam gets stuck between the pressure rollers, so it has been difficult to perform the foam creation process smoothly and efficiently.

It is an object of the present invention to provide a pressure-bonding, overlap-stitching form creating device that eliminates such drawbacks.

In order to achieve the above-mentioned object, the present invention provides a unit form in which a pressure-sensitive adhesive, which does not normally adhere but becomes adhesive when a predetermined pressure or more is applied, is applied to the overlapping surfaces. a superimposing means for superimposing continuous forms formed by connecting the above, a transport means for transporting the superimposed continuous forms, a cutting means for cutting the transported continuous forms in a superimposed state into unit forms; It has an appropriate pair of crimping rollers arranged opposite each other with a predetermined crimping interval set therein, and has an interval adjustment mechanism for setting and adjusting the crimping interval, and has a pressure-sensitive adhesive in a unit form transferred. and crimping means for binding the unit forms together by applying pressure with a roller.

Once the continuous form is stacked in a continuous state by a superimposing means, it is transferred by a transfer means, and after being cut into unit frames, a suitable pair of pressure rollers whose upper and lower crimping intervals can be adjusted are used. A predetermined pressure is applied by ζ, and the desired crimping and overlapping stitching form is created. The appropriate pairs of crimping rollers are disposed facing each other with predetermined crimping intervals set above and below, and the crimping intervals are adjustable, so that the crimping rollers are set at a crimping interval corresponding to the thickness of the unit form to be crimped. It is possible to set the pressure of the optimum strength to the unit form at all times.

It is provided with a transfer belt (not shown) for transfer and a bank stopper 83 provided at the end of transfer by this transfer belt.

Note that the rotational drive of the tractor 43 and other components described above, except for the rotation of the worm shaft 75 for adjusting the crimping interval, is caused by the driving force of the motor 15 shown in FIG. It is carried out by being transmitted through.

Next, the operation of the press-bonded, overlap-stitched form creating apparatus constructed as described above will be explained based on FIG. 1.

First, the folding means 20 is moved from the storage state shown in the imaginary line in FIG. Then, the continuous form 10, which is folded into a zigzag shape for each unit form 1 at each cutting/folding perforation 3 (see Fig. 6) and placed at a predetermined position, is passed through the υ bar 21 by twisting it. The front and back sides near each folding perforation 4 are pulled upward so that they come into contact with each guide bar 22, 23. Then, the continuous form IG is further passed between the guide plate 41 and the holding member 42, and its transfer hole 2 is engaged with the pin 44 of the tractor 43.

Further, each pressure roller 65a, 65b is pressed according to the thickness of the continuous form 1O in the folded state.

The crimping interval between 66a and 66b is adjusted to the optimum state for the folded unit form 1 to which pressure is to be applied. This adjustment can be made by operating the switch section 94 to
0 in a predetermined direction and rotate the worm shaft 75 in a predetermined direction, this can be easily done while checking the digital display on the display section 92.

In this state, when the motor 15 is started to operate the crimping and overlapping stitching form creating device, the tractor 43
The continuous form 10 pulled up by the stacking means 20 is folded into a two-character trifold state at each folding perforation 4, with the pressure-sensitive adhesives S facing each other, and then cut into a cutting means 50. will be transported towards. In this transfer process, the continuous form 10 is cut at its marginal part by a slitter 52, and then passed to a detector 53.
As a result of the reciprocating rotation of the rotary blade 54 in response to the tip detection signal, the unit form 1 is cut by the rotary blade 54 and the fixed blade 55 at the folding/cutting perforations 3, and sent to the crimping means 60.

The unit form l passes through the carry-in roller 63, is folded like a sheet of cardboard, and is then placed on each pressure roller 65a,
Due to the pressure applied when passing through 65 b, 66 a, and 66 b, the sealed letter 11 is completely bonded with the pressure-sensitive adhesive S.

In this way, by cutting the continuous form 10 into unit forms 1 before crimping, wrinkles, misalignment, etc. that occur during crimping do not accumulate, and the processing work can be continued smoothly.

The produced sealed letter 11 is sent to the stacking means 80 by the carry-out roller 70 with one end placed on the guide rod 81. Due to the action of the guide rod 81, excessive frictional force is not applied to the sealed letter 11, and the letter can be transferred smoothly. The sealed letter 11 abutted against the abutment member 82
are transported toward the bank stopper 83 by a transport belt (not shown), and are sequentially stacked in a predetermined state.

During this process, the unit form 1 is damaged by pressure rollers 65a, 65b, and 66a for some reason.

If a paper jam occurs due to wrapping around 66b,
The pressure rollers 65a, 65b, 66a.

By widening the vertical distance between 66b, the sandwiched unit form 1 can be easily removed.

After the processing operation is completed, the folding means 20 is raised again to the virtual line state shown in FIG.
4, it enters the stored state.

Note that the present invention is not limited to the above-mentioned embodiments; for example, the cutting means may be of a so-called burster type that utilizes the difference in transfer speed of rollers with different circumferential speeds, or the cutting means may be of a so-called burster type that utilizes the transfer speed difference of rollers with different circumferential speeds. Adjustment is done using upper roller 6.
5a and 66a may be moved.Furthermore, the drive mechanism for rotating the center gear 73 is a motor 90.
In addition to an electric type using a worm gear 76 and a worm wheel 74, which use the worm gear 76 as a rotational drive source, various configurations can be adopted, such as a manual type in which a rotary handle is directly connected to the center gear 73. Furthermore, the present invention is also applicable to a continuous copying form made of general one-time carbon-containing or carbonless paper that is not coated with pressure-sensitive adhesive S.
In this case, each pressure roller 65a, 65b, 66a, 6
It is sufficient to widen the vertical spacing of 6b to allow the continuous copying form to pass through without applying pressure.

As is clear from the above explanation, according to the present invention, since a continuous form is cut into unit forms and then crimped, wrinkles or bonding deviations do not occur during crimping, and The crimping interval of the crimping roller can be adjusted to the optimum crimping interval for the thickness of the unit form to which pressure is applied.
Pressing work can always be carried out in the optimum condition, and furthermore, even if a paper jam should occur, it can be easily removed by widening the vertical distance between the pressing rollers.
