Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a multi-page sealed letter in which a plurality of sets of folding papers are superposed and adhered so that a large number of pages are obtained when opened. When mailing a notification such as a medical examination to a citizen from a local government such as a city hall, a sealed letter with a large number of pages is required. That is, since a notice such as a medical examination has a huge amount of information to be notified, such as the examination item name, the person to be examined, the examination institution, the examination place, and the schedule, a letter with as many pages as possible is required.

2. Description of the Related Art Conventionally, in order to create such a multi-page letter, for example, as described in Japanese Examined Patent Publication No. 62-7000, a two-fold or three-fold continuous paper is made to run and continuous. A technique is known in which a letter is created by adhering three sides other than the fold line.

However, such a technique has a limit of three-folding, and if the number of sheets is extremely increased like five-folding or six-folding, it is too thick and the device does not operate smoothly, so that an accurate envelope cannot be created. . Therefore, conventionally, the local government has mailed the mail in two to four times.

[0003]

As described above, since it is sufficient to mail at once, the mail is divided into two to four parts, and therefore the mailing cost increases, and the taxpayer's burden increases accordingly. And lacked resident services.

A technical problem of the present invention is to pay attention to such a problem, and to make it possible to record a huge amount of information and to make a multi-page sealed letter that can be announced without increasing the number of folds extremely. So, it is possible to mail a multi-page letter at one time.

[0005]

The technical problem of the present invention is solved by the following means. According to a first aspect of the present invention, in a multi-page letter-sealing apparatus, at least a continuous paper feeder, a left and right paper feed margin separating portion, a top / bottom separating means, and an adhesive machine are provided. When feeding multiple folded paper sheets that are folded in two or more by the paper feeder in a state of stacking multiple sets, fold multiple paper feeding means with a folding device in the stage before the paper feeder and It is a method of creating a multi-page letter, which is characterized in that folding paper is fed from a container to a paper feeder.

As described above, since a plurality of sheet feeding means with a folding device are arranged in front of the paper feeding device and the folding paper is fed from each folding device to the paper feeding device, a single sheet feeding device is used. It is possible to feed multiple sets of folding paper that are folded in two or more into the paper feeder and stack them. Therefore, since a plurality of sets of sheets can be directly bonded to the bonding machine and bonded in a state of being stacked, a multi-page sealed letter can be realized, and a huge amount of information can be recorded and mailed.

According to a second aspect of the present invention, in addition to the sheet feeding means with the folding device according to the first aspect, a sheet feeding means for a single continuous page paper without a folding device is provided, and the single continuous page paper is the paper sheet. It is a method of creating a multi-page letter, which is characterized by sending it to a feeder.

As described above, in addition to the above-mentioned sheet feeding means with a folding device, a sheet feeding means for a single continuous page is provided, and the single continuous page is fed to the paper feeder. As described above, it is possible to superpose a single continuous page paper on the folded paper in the folded state, feed the paper with the paper feeder, and bond them with the adhesive machine.

According to a third aspect of the invention, a single-stage or multiple-stage front-stage paper feeder is arranged in front of the paper-feeder according to claim 1 or 2, and the front-stage paper feeder is used, It is a method of making a multi-page sealed letter, characterized in that the folded paper is fed into the paper feeder.

As described above, a single-stage or multiple-stage front-stage paper feeder is arranged in front of the above-mentioned paper feeder, and folding paper is fed into the above-mentioned paper feeder through the front-stage paper feeder. According to this, it is possible to eliminate or minimize the deviation of the paper feed holes between the folded sheets fed to the paper feeder, and the paper feed operation in the paper feeder is smoothly performed.

According to a fourth aspect of the present invention, there is provided a multi-page letter-sealing apparatus, which comprises at least a continuous paper feeder, left and right paper feeding margin separating portions, top and bottom separating means, and an adhesive bonding machine. In front of the paper feeder, there is a single-stage or multiple-stage front-stage paper feeder, and a structure capable of feeding a plurality of sets of folding paper folded in two or more folds to the front-stage paper feeder. This is a multi-page sealed letter creation device.

As described above, a single- or multi-stage front-stage paper feeder is provided in front of the above-mentioned paper feeder, and a plurality of sets of folding papers folded in two or more are added to the front-stage paper feeder. Due to the feeding structure, the pre-stage paper feeder eliminates or minimizes the deviation of the paper feed holes between the folding sheets fed into the paper feeder. As a result, the paper feeding operation of the paper feeder is smoothly performed.

A fifth aspect of the present invention is an apparatus for producing a multi-page sealed letter, wherein the cross-sectional shape of the paper feeding pin of the pre-stage paper feeding apparatus according to the fourth aspect is sufficiently smaller than the diameter of the paper feeding hole for the paper feeding margin. . In this way, the cross-sectional shape of the paper feed pin of the pre-stage paper feeder is sufficiently smaller than the paper feed hole for the paper feed allowance, so the paper feed holes of the folded sheets in the overlapped state are slightly misaligned. Also, the paper feed pins can be inserted into the paper feed holes of the respective folded sheets to reliably feed the paper. Then, the deviation of the paper feed hole is gradually eliminated or reduced.

According to a sixth aspect of the present invention, the cross sectional shape of the paper feed pin according to the fifth aspect is sufficiently smaller than the diameter of the paper feed hole for the paper feed margin.
Moreover, the multi-page letter-sealing device has a flat or elliptical shape in the front-rear direction.

As described above, when the cross-sectional shape of the paper feed pin is sufficiently smaller than the paper feed hole for the paper feed allowance and is flat or elliptical in the front-rear direction, the folded paper sheets in the overlapped state. Even if the deviation amount of the paper feed holes is large, the paper feed pins can be fitted into the paper feed holes of the folding sheets to reliably feed the paper. Then, the deviation of the paper feed hole is gradually eliminated or reduced.

A seventh aspect of the present invention is the apparatus for producing a multi-page sealed letter according to the fifth or sixth aspect, wherein the tip of the paper feed pin is tapered. In this way, if the tip of the paper feed pin is tapered, the paper feed pin feeds each folded paper even if the deviation of the paper feed hole between the incoming folding paper is large. It is easy to fit in the hole,
You can reliably feed the paper.

According to an eighth aspect of the present invention, the pre-stage paper feeder according to any one of the fourth to seventh aspects can be moved toward and away from the paper feeder in a direction more or less freely. It is a device for creating multi-page sealed letters.

As described above, since the pre-stage paper feeder is able to move toward and away from the above-mentioned paper feeder to some extent and move toward and away from the paper feeder, the paper feed holes for the incoming folding sheets are fed. Even if the deviation amount is large, the paper feed pin side follows the deviation of the paper feed hole, and the paper feed pin easily fits into the paper feed hole of each folded paper. As a result, the front-stage paper feeder can reliably feed the paper even when the paper is misaligned.

When an unreasonable force is applied to the pre-stage paper feeder from the continuous paper, the pre-stage paper feeder moves,
The impact can be mitigated. Further, due to vibrations caused by the forward and backward movements of the former-stage paper feeder, overlapping folded sheets are separated from each other, and the deviation of the sheet feeding holes between the incoming folded sheets is smoothly eliminated or reduced.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment will be described of how the method and apparatus for producing a multi-page sealed letter according to the present invention are practically embodied. FIG. 1 is a perspective view showing an embodiment of a multi-page sealed letter produced according to the present invention, in a state after opening.

Since this multi-page sealed letter is made by stacking two sets of three-folded folding sheets of three sheets, it consists of a total of six page sheets P1 ... P6 and has 12 pages.
That is, as many as 6 page papers P1 ... P6 are bound in the shape of a thin booklet with the binding edge 1 at the left end,
More than twice the amount of information can be recorded. The front side (first page) of the first page paper P1 is a column for displaying the destination address.

2 and 3 show an embodiment of a foldable paper for producing the multi-page sealed letter of FIG. That is, the multi-page sealed letter according to the present invention is created by stacking and adhering the folding paper 2 of FIG. 2 on the folding paper 3 of FIG.

FIG. 2 is a perspective view showing the details of the folding paper 2 on the upper side. (1) is a perspective view seen from the side of the first page (first page), and (2) is the upside down final page ( It is the perspective view seen from the (6th page) side. The page number when binding in a booklet is displayed on each page. As is clear from (1), the folding paper 2 has folds 4a and 4b.
Is folded in three in a zigzag shape, and 3 pages of paper P
It has a shape in which 1, P2, and P3 are folded.

When three page sheets P1, P2, P3 are folded and overlapped, the vertical and horizontal sizes are the same, but 1
The left end of the sheet P1 is provided with a paper feed allowance 6 of the paper feed hole 5, and the right end of the third sheet P3 is provided with a paper allowance 7 of the empty paper feed hole 5. These paper feeding fees 6, 7
Is cut from the position of the dashed line before the bonding operation.

Each of the page papers P1, P2, P3 must be folded so that adjacent pages are adhered to each other so that the internal information cannot be seen during mailing. Since the inside of the folds 4a and 4b is closed by the folds 4a and 4b and the inside cannot be seen, adhering between adjacent pages is sufficient only on three sides other than the positions of the folds 4a and 4b.

Therefore, the adhesive portion 8 on the back side (the second page) of the first page paper P1 on the three sides and the adhesive portion 9 on the front side of the second page paper P2, that is, the adhesive portion 9 on the three sides of the third page. ,
They are glued together and sealed so that the interior is not visible.
The broken line indicates the hidden position on the back side.

The adhesive portion 10 on the back side of the second page paper P2, that is, the three sides of the fourth page is not shown in FIG. 1A, but is shown in FIG. 2B. The third side adhesive portion 10 of the fourth page and the front side of the third page paper P3, that is, the third side adhesive portion 11 of the fifth page are adhered to each other and sealed so that the inside cannot be seen. It

The three page papers P1, P2, P3 have perforations m1 inside the top side adhesive parts 8, 10, 11 and perforations inside the ground side adhesive parts 8, 9, 11. Eye m2
have. Also, the first and second page sheets P1,
P2 has perforations m3 on the side on the right fold 4a side, and the third page paper P3 has perforations m4 on the side on the paper feed margin 7 side.

Therefore, these perforations m1 and m
When 2, m3 and m4 are separated and the fold line 4a and the adhesive portion between adjacent pages are removed, the package can be opened and each page can be opened to see the inside.

Since there is no perforation on the side of the paper feed margin 6 side of the second page and the fold 4b side of the third page, the respective adhesive portions 8 and 9 remain adhered and cannot be separated.
That is, the left end side is the portion that becomes the binding portion 1 in FIG. 1, and the second and third pages remain bonded even after opening. 4th and 5th pages are folds 4
Since it is connected from the beginning via b, there is no need for adhesion.

The folding paper 2 having such a structure is laminated and adhered to the folding paper 3 as shown in FIG. For this adhesion, an adhesion portion 13 as shown in FIG. 2B is provided on the back surface of the third page paper P3, that is, on the final page (sixth page). The adhesive portions 13 are provided on all four sides, the top side, the ground side, and the left and right.

Since the third page paper P3 also has perforations m1 on the top side, perforations m2 on the ground side, and perforations m4 on the paper feed margin 7 side, the perforations are cut and opened. Thus, the last page (sixth page) and the first page (first page) of the folding paper 3 in FIG. 3 can be seen. Since there is no perforation on the fold 4b side, the adhesive portion 13 of the final page (sixth page) and the adhesive portion of the first page (first page) of the folding paper 3 of FIG. It becomes the binding unit 1.

FIG. 3 is a perspective view showing the details of the next folding paper 3 to be laminated and adhered on the folding paper 2 described above, and each page displays the page number when bound in a booklet form. is there. This folding paper 3 is also the same as the folding paper 2 of FIG. 2 and has three page papers P1, P2, P of the same size.
3 is folded in three in a zigzag shape at folds 4a and 4b, and has a shape in which three page papers P1, P2, and P3 are folded.

A paper feeding margin 6 is attached to the left end of the first page paper P1, and a paper feeding margin 7 is attached to the right end of the third page paper P3.

The adhesive portion 8 on the back side (8th page) of the first page paper P1 on the three sides and the front side of the second page paper P2, that is, the adhesive portion 9 on the 3rd side of the 9th page. , Glued to each other and sealed so that the inside cannot be seen.

The back side of the second page paper P2, that is, 10
Although the adhesive portion 10 on the three sides of the page does not appear in this figure, it does appear in FIG. 2 (2). The third side adhesive portion 10 of the tenth page and the front side of the third page paper P3, that is, the third side adhesive portion 11 of the eleventh page are adhered to each other and sealed so that the inside cannot be seen. It

The three page papers P1, P2, P3 have perforations m1 inside the top-side adhesive parts 8, 11 and perforations m2 inside the bottom-side adhesive parts 8, 9, 11. have. The first and second page papers P1 and P2 have perforations m3 on the side of the fold 4a, and the perforation m4 of the third page paper P3 on the side of the paper feed margin 7 side. have.

Therefore, these perforations m1 and m
When 2, m3 and m4 are separated and the fold line 4a and the adhesive portion between adjacent pages are removed, the package can be opened and each page can be opened to see the inside.

Since there is no perforation on the side of the 8th page on the paper feed margin 6 side and on the side of the 9th page on the fold 4b side, the respective adhesive portions 8 and 9 remain adhered and cannot be separated. That is, the left end side is the portion that becomes the binding portion 1 in FIG. 1, and the eighth and ninth pages remain bonded even after opening. Since the 10th and 11th pages are connected from the beginning through the fold line 4b, there is no need for adhesion.

In this way, the second set of folding paper 3 is also 1
It has basically the same configuration as the folding paper 2 of the set.
The difference is that the first page (7
The last page of the folding paper 2 (6th page)
Just like the (page), the adhesive portions 12 are provided on the top side, the ground side, and all four sides on the left and right.

As described above, the adhesive portions 12 on the four sides of the first page of the second set of folding paper 3 are overlapped with the adhesive portions 13 on the four sides of the last page of the first set of folding paper 2, and are adhered. By pressing the portion, the last page of the first set of folding paper 2 is overlapped on the first page of the second set of folding paper 3 and is bonded at the four sides.

The first page paper P1 of the second set of folding paper 3 also has perforations m1 on the top side, perforations m2 on the ground side, and perforations m3 on the fold 4a side.
By separating and opening the perforations, the last page (6th page) of the folding paper 2 and the first page (7th page) of the folding paper 3 can be seen. Since there is no perforation on the paper feed margin 6 side, the adhesive portion 12 of the first page (7th page) and the adhesive portion 13 of the last page (6th page) of the folded paper 2 of FIG. 2 remain adhered. , The binding unit 1 in FIG.

Next, two sets of such folding papers 2 and 3 are used.
An apparatus and method for stacking and adhering to form a sealed letter will be described. FIG. 4 is a side view of the multi-page sealed letter creating apparatus. In the paper feed table 21, the folded paper 2 is not folded into three and is expanded, and is folded in zigzag at the top and bottom of the folded paper 2.

Between the paper feed table 21 and the paper feeder 23, a folding device 24 for folding in three and a guide means 25 are arranged as required, as shown in FIG.

On the other paper feed table 22, the folding paper 3 is placed.
Folded paper 3
It is folded in the zigzag shape by bending it at the top and bottom of the. A folding device 26 for folding in three is arranged between the paper feeding device 23 and the paper feeding device 23, as shown in FIG.

Therefore, the continuous paper on the paper feed table 22 is fed to the paper feeder 23 side after being folded in three by the folding device 26. Similarly, the continuous paper on the paper feed table 21 is also fed to the paper feeder 23 side after being folded in three by the folding device 24. At this time, the continuous folding paper 3a folded in three is fed to the paper feeder 23 in a state where the continuous folding paper 2a folded in three is overlapped on the continuous folding paper 3a in a folded state. Depending on the paper feed allowance separator 27
Sent to. The paper feeder 23 has a known tractor structure, and its feed pins are inserted into the paper feed holes 5 of the paper feed allowances 6 and 7 to feed the paper.

The next paper feed margin separator 27 is provided with a margin slitter, which cuts the paper feed margins 6 and 7 on the left and right sides of the folding sheets 2 and 3 shown in FIGS. The two sets of continuous folding paper from which the paper feeding margin has been separated and removed are separated by the next detacher 28 into top and bottom.

That is, the base portion of each page paper P1, P2, P3 is continuous with the top portion of the next page paper P1, P2, P3 via the perforations, and zigzag on the paper feed trays 21, 22. It is folded into a shape. Therefore, if a tensile force is applied to the perforation between the top and the ground, each page paper P
The position of the ground of 1, P2, P3 is the next page paper P1, P2,
It is torn and separated from the heavenly position on P3. as a result,
Each multi-page letter will be independent.

The detacher 28 includes two roller pairs R
1, R2 and paper pad 29. Roller pair R
Each of the rollers constituting R1 and R2 is normally separated from each other, and two sets of folding papers 2a and 3a pass between them, and when the top and bottom of the continuous paper are separated, they are momentarily brought close to each other. The folding papers 2a and 3a are rotated while being sandwiched therebetween.

That is, the rotation numbers of the roller pair R1 and R2 are the same, but the diameters of the rollers are different. That is,
The roller pair R2 is slightly larger than the roller pair R1, and therefore the paper feed speed when the continuous paper is sandwiched between the rollers is
The roller pair R2 side is slightly faster than the roller pair R1 side. Due to this speed difference, the continuous paper is pulled at the position of the top and the ground, and torn at the perforation position between the top and the ground, and becomes independent for each envelope.

The envelope paper cut off at the perforations is sent by the conveyor 30 to the press roller 31 of the next bonding machine, and the bonding portions described with reference to FIGS. 2 and 3 are pressed and bonded. The sealed letters thus bonded are stocked as 33 in the next stacker 32. Box 3
Control equipment is stored in 4.

In the illustrated embodiment, two sets of three-fold folding papers 2 and 3 are stacked and adhered, but not limited to three-fold, two-fold or four-fold or more folding paper may be used. Also, three or more sets of folding paper may be stacked and adhered. In this case, needless to say, the number of paper feed trays 21 and 22 is also increased to three or more.

Further, when it is sufficient to add one or two pages to the folding paper, that is, only one sheet of paper, it is sufficient to bond one single page paper to one set or two or more sets of folding paper. It is also possible to do so.

In the case where only one sheet is stacked and adhered in this way, in addition to the folding unit-equipped sheet feeding units 21 and 22, a sheet feeding unit for a single continuous page sheet without a folding unit is provided, and a single sheet feeding unit is provided. The continuous page paper of No. 2 is fed to the paper feeder 23.

As described above, when two or more sets of folding paper or single page paper are stacked and fed to the paper feeder, the position and orientation of the paper feed tray are arbitrary and are not particularly limited. It is also free to dispose an appropriate continuous paper guide means or the like between each paper feed tray and the paper feeder 23.

The bonding means in the bonding machine 31 is not particularly limited, but various known bonding means such as thermocompression bonding and pressure bonding can be adopted.

In the embodiment shown in FIG. 5, a pre-stage paper feeder 35 is arranged in front of the paper feeder 23 shown in FIG. Therefore,
The continuous paper on the paper feed table 22 is supplied to the pre-stage paper feeder 35 side in a state of being folded in three. Similarly, the continuous paper on the paper feed table 21 is also folded in three and supplied to the pre-stage paper feeder 35.

At this time, the pre-stage paper feeder 35 is fed in a state in which the continuous folding paper 2a in the tri-fold state is superposed on the continuous folding paper 3a in the tri-fold state, and is continuously folded. After the positional deviation of the paper feed holes 5 between the papers 2a and 3a is eliminated or minimized, the paper is fed to the next paper feeder 23 and then to the paper feed margin separator 27.

Next, referring to FIG. 6, details of the pre-stage paper feeder 35 will be described. The pre-stage paper feeder 35 is also the paper feeder 2 described above.
It has a tractor structure similar to No. 3, and is arranged on the left and right according to the paper width. That is, the paper feed pin 36 of the left front-stage paper feeder 35 is fitted into the paper feed hole 5 of the left-side paper feed allowance 6 in FIGS. 2 and 3, and the paper feed pin 36 of the right front-stage paper feeder 35 is , The paper feed allowance 7 on the right side of FIGS. 2 and 3 is inserted into the paper feed hole 5.

At this time, if the paper feed hole 5 of the upper folding paper 2 and the paper feed hole 5 of the lower folding paper 3 are exactly aligned with each other, there is no problem. Moreover, as the number of folds increases, a phenomenon may occur in which the paper feed hole 5 of the upper fold paper 2 and the paper feed hole 5 of the lower fold paper 3 are gradually displaced. Then, there arises a problem that the shift amount is gradually accumulated.

Therefore, in the case of the pre-stage paper feeder 35, FIG.
As in (1), the paper feed pin 36 has a sufficiently small diameter with respect to the paper feed hole 5. That is, the diameter of the paper feed pin 36 is sufficiently smaller than that of the paper feed hole 5. Normal paper feeder 2
In the case of 3, the paper feed pin is equal to or slightly smaller than the paper feed hole, but in the case of the pre-stage paper feeder 35, since the diameter of the paper feed pin 36 is sufficiently smaller than the paper feed hole 5, Between the feed pin 36 and the paper feed hole 5, a gap G, G is formed in the front and rear.
You can That is, a gap of 2G is formed as a whole.

Therefore, the paper feed hole 5 of the upper folding paper 2 and the paper feed hole 5 of the lower folding paper 3 are 2G at maximum.
Even if they are misaligned, the paper feed pins 36 can be inserted into both the paper feed holes 5 and 5 to feed the paper. Also, at first,
Only the upper folding paper 2 is pushed in the paper feeding direction by the paper feeding pin 36, and the lower folding paper 3 is pressed by the paper feeding pin 36.
Even if the feeding force of the lower folding paper 3 is not applied, the load in the direction of the arrow a3 is applied from the side of the paper feed table 22. The paper feed pin 36 comes into contact with 5 as well, and a force in the paper feed direction acts.

As a result, even if the paper is misaligned at the time of entering the pre-stage paper feeder 35, when the paper leaves the front-stage paper feeder 35 and advances, the upper and lower folding papers 2 and 3 are fed. The misalignment of the holes is eliminated and the sheets are fed to the next paper feeder 23 in a state of being exactly overlapped, so that the paper feeding operation in the paper feeder 23 is smoothly performed. Or at least
The shift amount of the paper feed holes of the upper and lower folding sheets 2 and 3 is reduced.

FIG. 7B shows an example in which the paper feed pin 36 has a sufficiently small diameter and is flat in the front-back direction. In addition, FIG. 7C is an example in which a flat elliptical shape is formed in the front-rear direction. In this way, if the front-rear direction is made flat or elliptical, the front-rear direction gap G can be increased, and the paper can be fed even if the deviation amount of the paper feed holes of the upper and lower folded sheets increases.

The left and right front-stage paper feeders 35, 35 in FIG.
The left and right bearings 38, 38 are attached to the coil spring 3
9, 40 are pulled in the front-rear direction, that is, the apparatus main bodies 41, 42 side. Alternatively, it may be pushed using a compression coil spring. The drive motor M is mounted on the bearing 38.

Therefore, the front-stage paper feeder 35 can move to some extent in the front-back direction, that is, in the paper feeding direction. As a result, even if the amount of deviation of the paper feed holes between the folding papers 2 and 3 coming in is large, the paper feed pin 36 side follows the deviation of the paper feed holes, and the paper feed holes of the respective folded papers 2 and 3 are moved. It becomes easy to fit in. As a result, in the front paper feeder 35,
You can reliably feed paper in the overlapping state.

Further, when an unreasonable force is applied to the front-stage paper feeder 35 from the continuous paper, the front-stage paper feeder 35 is moved, so that the unreasonable force acts on the continuous paper.

Further, due to the forward / backward movement of the pre-stage paper feeder 35, the amount of deviation of the paper feed holes between the folding papers coming in is easily reduced. That is, in FIG. 7 (1), only the upper folding paper 2 is pushed in the paper feeding direction indicated by the arrow A, but the pre-stage paper feeder 35 moves back and forth, or shakes,
When the friction between the upper and lower folding papers 2 and 3 is reduced and separated, only the upper folding paper 2 moves forward, and soon the lower folding paper 3 also pushes the paper feed pin 36 into the paper feed hole. Become. As a result, the positional deviation between the upper and lower paper feed holes is gradually and smoothly eliminated.

The pre-stage paper feeder 35 is not limited to a single unit, but may be provided in a plurality of stages. In that case, the pre-stage paper feeder 35 near the paper feeder 23 is arranged so that the gap G becomes small and the paper feed pin 3
6 is thickened, and the pre-stage paper feeding device 35 near the paper feeding table thins the paper feeding pin 36. As a result, the upper and lower folding paper 2,
The positional deviation of the paper feed hole 3 is gradually reduced by each pre-stage paper feeder.

The concept of thinning the paper feed pin as shown in FIG. 7 can be applied to the paper feeder 23.

[0071]

According to the first aspect of the present invention, a plurality of sheet feeding means with a folding device are arranged in front of the paper feeding device, and the folding paper is fed from each folding device to the paper feeding device. Therefore, it is possible to feed and stack a plurality of sets of folding paper folded in two or more into a single paper feeder. Therefore, send it to the bonding machine as it is,
Since multiple sets can be glued together, a multi-page sealed letter can be realized and a huge amount of information can be recorded and mailed.

According to a second aspect of the present invention, a method of feeding a single continuous page paper in addition to the folding unit-equipped paper feeding means, and feeding a single continuous page paper to the paper feeder. According to this, it is possible to stack a single continuous page paper on a folded paper folded in two or more, feed the paper with a paper feeder, and bond it with an adhesive machine.

According to a third aspect of the present invention, a single or a plurality of pre-stage paper feeders are arranged in front of the paper feeder, and folding paper is fed through the pre-stage paper feeder. According to the method of feeding the paper into the paper feeding device, the deviation of the paper feeding holes between the folding sheets fed into the paper feeding device can be eliminated or minimized, and the paper feeding operation in the next paper feeding device can be smoothly performed. .

According to a fourth aspect of the present invention, a single-stage or multiple-stage pre-stage paper feeder is provided in front of the above-mentioned paper feeder, and the folded paper is folded into two or more folds on the pre-stage paper feeder. Because of the structure in which a plurality of sets can be fed, the deviation of the paper feed holes between the folding sheets fed into the paper feeder is eliminated or minimized by the pre-stage paper feeder. As a result, the paper feeding operation of the paper feeder is smoothly performed.

Since the cross-sectional shape of the paper feed pin of the pre-stage paper feeder is sufficiently smaller than the paper feed hole for the paper feed allowance, the paper feed between the folded sheets in the overlapping state is carried out. Even if the holes are slightly misaligned, the paper feed pins can be fitted into the paper feed holes of the respective folded sheets to reliably feed the paper. Then, the deviation of the paper feed hole is gradually eliminated or reduced.

When the paper feed pin has a cross-sectional shape that is sufficiently smaller than the paper feed hole of the paper feed allowance and is flat or elliptical in the front-rear direction, the paper feed pins are overlapped. Even if there is a large amount of misalignment between the paper feed holes between the folded sheets,
The paper feed pins can be fitted into the paper feed holes of the respective folded sheets to reliably feed the paper. Then, the deviation of the paper feed hole is gradually eliminated or reduced.

When the tip of the paper feed pin is tapered in a taper shape as described in claim 7, even if the deviation amount of the paper feed holes between the incoming folding sheets is large, the paper feed pins are different from each other. It is easy to fit the paper into the paper feed hole of the folded paper, and the paper can be fed reliably.

According to the eighth aspect of the present invention, since the pre-stage paper feeder can move toward and away from the paper feeder to some extent and move toward and away from the paper feeder, the folding papers coming in from each other can be approached. Even if the deviation amount of the paper feed hole is large, the paper feed pin side follows the deviation of the paper feed hole, and the paper feed pin easily fits into the paper feed hole of each folded sheet. As a result, the front-stage paper feeder can reliably feed the paper even when the paper is misaligned.

When an unreasonable force is applied to the pre-stage paper feeder by the continuous paper, the pre-stage paper feeder moves,
The impact can be mitigated. Further, due to vibrations caused by the forward and backward movements of the former-stage paper feeder, overlapping folded sheets are separated from each other, and the deviation of the sheet feeding holes between the incoming folded sheets is smoothly eliminated or reduced.
