Description

  The present invention relates to a pressure-sensitive paper sheet manufacturing apparatus using cut paper-like paper sheets for manufacturing pressure-sensitive paper sheets usable for direct mail, postcards, reciprocal postcards, sealed letters, and the like. Specifically, although the appearance is normal direct mail, postcards, reciprocal postcards, sealed letters, etc., the sheets folded in multiple layers are pressure-bonded and laminated via a pressure-bonding film, so the inside The present invention relates to a pressure-bonding film insertion means in a pressure-sensitive paper sheet manufacturing apparatus for manufacturing pressure-sensitive paper sheets capable of concealing a large amount of information from cut paper-like paper sheets.

Recently, as postal items such as postcards, a large number of pieces of information can be sent by folding paper sheets in which multiple pieces of displayed information are connected via a fold line, and by bonding the opposing leaf pieces in a peelable manner. Many crimped paper leaves are used.
For example, Japanese Patent Application Laid-Open No. 5-38894 and Japanese Patent Application Laid-Open No. 9-76665 disclose a pressure-sensitive paper sheet manufacturing apparatus as described above. Each paper sheet is formed by connecting a plurality of leaf pieces via a folding line. A sheet conveying means, a sheet folding means for folding each sheet on the sheet conveying path, and a two-layer transparent film bonded in a peelable manner and bonded to the front and back surfaces by pressure or heating and pressing A pressure-bonding film supply means for successively supplying a long pressure-bonded film formed with an adhesive layer for producing a property along a predetermined pressure-bonding film supply path, and a paper sheet conveying path downstream from the paper sheet folding means. In a crossing area with the pressure-bonding film supply path, pressure-bonding film insertion means for inserting a pressure-bonding film between any opposing leaf pieces in the folded paper sheets, and paper sheet conveyance downstream from the pressure-bonding film insertion means Above, a paper sheet pressure bonding means for releasably adhering between both leaf pieces in the paper sheet into which the pressure bonding film is inserted through the pressure bonding film under pressure or heating and pressure, and a paper sheet pressure bonding means On the upstream or downstream paper sheet conveyance path, there has been proposed one having a basic structure including a paper sheet cutting means for cutting the paper sheet into which a pressure-bonding film is inserted into a predetermined size.

  The pressure-sensitive paper sheets obtained by the manufacturing apparatus are opened between the two leaf pieces that have been pressure-bonded as described above, whereby the two transparent film layers of the pressure-bonded film sandwiched between the leaf pieces are peeled, As a result, the pressure-sensitive paper sheets are unfolded in a state where the information display surface of each leaf piece is covered with the transparent film and the information on each leaf piece can be seen through the transparent film.

In the above-mentioned crimped paper sheets, the information on each leaf piece is not visible from the outside until it is peeled and unfolded on the recipient side, so it is excellent in confidentiality such as privacy protection, and much more in comparison with single-leaf letters etc. Information can be sent at a normal charge, so the transmission cost for the information charge is greatly reduced, and the information on each leaf piece is covered with a transparent film, so it has excellent information storage, water resistance, stain resistance, etc. It also has the effect of facilitating information transmission by giving aesthetics to information.
However, any of the manufacturing apparatuses is generally mass-produced, and when large companies such as mail-order sales and distance learning regularly notify a large number of members, such a large-scale manufacturing apparatus is used. Due to the extreme increase in the unit price of crimped paper leaves, it was impossible to handle small lot production.

In particular, the pressure-sensitive paper sheet manufacturing apparatus disclosed in Japanese Patent Laid-Open No. 5-38894 requires a continuous form printing machine as a paper sheet, and is generally used for output of a personal computer, for example, in small and medium offices and homes. However, this printer has a problem that it cannot cope with the printing of the continuous form paper.
Further, in the pressure-sensitive paper sheet manufacturing apparatus disclosed in Japanese Patent Laid-Open No. 9-76665, since the discontinuous cut paper that is conveyed one by one is used as the paper sheet, the above-mentioned problem regarding the printing of the paper sheet is In the pressure-bonding film insertion means in this manufacturing apparatus, while the paper sheet to be conveyed is being folded, the pressure-sensitive film is supplied at the same speed as the paper sheet while the paper sheet is opposed. It requires a difficult work of continuously inserting it into the box.

  On the other hand, the invention relating to the apparatus for manufacturing a pressure-sensitive paper sheet using cut paper-like paper sheets, in which the means for inserting the pressure-bonding film between the leaf pieces of the paper sheet is particularly improved, the structure is simple and the size can be reduced, It was completed by JDL Engineering Co., Ltd. in cooperation with the present applicant, and was filed as Japanese Patent Application No. 2001-296979 on May 2, 2002. This patent application is currently shared between JDL Engineering Co., Ltd. and the present applicant, KDK Corporation.

  In the pressure-sensitive paper sheet manufacturing apparatus according to Japanese Patent Application No. 2001-296979, the pressure-bonding film insertion means is provided movably up and down in the crossing area between the paper sheet conveying path and the pressure-sensitive film supply path downstream from the paper sheet folding means. A support plate for placing the supplied pressure-bonding film on the upper surface, and a paper sheet that is provided so that the support plate can be driven up and down and is folded so that the lower leaf piece is slightly longer than the upper leaf piece. And when the upper leaf piece of the paper sheet is disposed upstream of the support plate and the lower leaf piece is disposed below the support plate, the support plate is lowered integrally with the pressure-bonding film. Accordingly, the lower leaf piece is pushed down to forcibly open the space between the two leaf pieces, and the paper sheets opened between the two leaf pieces are sent toward the support plate on which the pressure-bonding film is placed and Therefore, it includes a paper sheet feeding means for simultaneously inserting the support plate and the pressure-bonding film between the both leaf pieces, and further removing only the support plate from the paper sheets having the support plate and the pressure-bonding film inserted between the both leaf pieces. Thus, there is a substantial need for a support plate removing means for making the paper sheet into a state in which only the pressure-bonding film is inserted between the both leaf pieces.

As a result of independently repeating experiments under various conditions for the pressure-bonding film insertion means having the above structure, the pressure-sensitive film insertion means using a support plate, for example, paper sheets, Depending on the model of the printer used, the printing method, printing conditions, etc., it will be exposed to high temperatures, causing extreme curling and uneven deformation on the surface. As a result, both the leaf pieces in the folded paper sheet are wavy. Even when the lower leaf piece is pushed down as the support plate is lowered as described above, the two leaf pieces are not sufficiently opened, and the pressure-bonding film between the two leaf pieces is smooth in the manner described above, particularly in high-speed continuous operation. I found that there is a new problem that will not be inserted into.
In view of such a problem, the problem to be solved by the present invention is to use a paper sheet that is curled during the printing process and has irregularities on its surface in a press-bonded paper sheet manufacturing apparatus that uses cut paper-like paper sheets. Even in such a case, it is an object of the present invention to provide a pressure-bonding film insertion means capable of inserting a pressure-sensitive film between both leaf pieces of a folded paper sheet smoothly and at high speed without occurrence of jamming or the like.

In order to achieve the above object, the pressure-bonding film inserting means in the pressure-sensitive paper sheet manufacturing apparatus according to the present invention provides a predetermined sheet-shaped paper sheet, in which a plurality of leaf pieces are connected via a folding line, from a sheet feeding unit. Paper sheet conveying means for sequentially conveying along the paper sheet conveying path, paper sheet folding means for folding each paper sheet on the paper sheet conveying path, and a two-layer transparent film bonded in a peelable manner And a pressure-bonding film supply means for sequentially supplying a long pressure-bonded film formed on the front and back surfaces with an adhesive layer that generates adhesiveness by pressing or heating and pressing along a predetermined pressure-bonding film supply path, and paper A pressure-bonding film insertion means for inserting a pressure-sensitive film between any opposing leaf pieces in the folded paper sheets at the intersection of the paper sheet conveyance path and the pressure-sensitive film supply path downstream from the leaf folding means; A paper sheet that adheres in a peelable manner through the pressure-bonding film under pressure, heating, or pressure between the two leaf pieces of the paper sheet into which the pressure-sensitive film is inserted on the paper sheet conveyance path downstream from the attachment film insertion means. For cut paper comprising: a sheet pressure bonding unit; and a sheet cutting unit that cuts the sheet into which the pressure-bonding film is inserted into a predetermined size on a paper sheet conveyance path upstream or downstream of the sheet pressure bonding unit. The pressure-bonding film insertion means in the pressure-sensitive paper sheet manufacturing apparatus,
The support plate is provided so as to be movable up and down in the crossing area, and the supplied pressure-bonding film is placed up and down, and provided so that the support plate can be driven up and down, so that the lower leaf piece is slightly longer than the upper leaf piece. When the folded paper sheet is conveyed to the crossing area, the upper leaf piece of the paper sheet is arranged on the upstream side of the support plate, and the lower leaf piece is arranged below the support plate, the support plate The pressure-sensitive film is placed on the support plate driving means for forcibly lowering the lower leaf piece and thereby forcibly opening the space between both leaf pieces by pressing down the lower leaf piece. Paper sheet feeding means for simultaneously inserting the support plate and the pressure-bonding film between the two leaf pieces, and the support plate from the paper sheet in which the support plate and the pressure-bonding film are inserted between the two leaf pieces. Only Rutotomoni In thus composed of a support plate extraction means, to which only the bonding film sheet on both leaf pieces is inserted structure,
The paper sheets folded so that the lower leaf pieces are slightly longer than the upper leaf pieces are conveyed to the crossing area, and the upper leaf pieces of the paper sheets are arranged on the upstream side of the support plate, and the lower leaf pieces are supported. When it arrange | positions under a board, the opening part of both leaf pieces has faced the upper direction with respect to the support board, It is characterized by the above-mentioned.

  According to the above configuration, when the paper sheets having both leaf pieces opened by the paper sheet feeding means are fed toward the support plate on which the pressure-bonding film is placed, the opening portions of the both leaf pieces are relative to the support plate. Looking up. Therefore, even if the paper sheet is curled by the printing process and the surface is uneven, if the lower leaf piece is pushed down by the support plate, the upper leaf piece opens greatly upwards, The support plate and the pressure-bonding film can be inserted smoothly.

  The cut sheet-like paper sheets used for the pressure-bonding film inserting means include not only the simplest form of paper sheets in which two connected leaf pieces are folded in two, but also three connected sheets. Folding the leaf pieces in a zigzag direction in a tri-fold with a Z-shaped cross-section or folding them in one direction into a tri-fold in a C-shaped cross-section, or four or more connected leaf pieces in a zigzag direction in a bellows manner It is possible to use paper sheets or the like that are folded, folded so as to be wound in one direction, folded in a folding manner from both sides to the center direction, or folded in a mixed manner, and any paper sheets are opposed to each other. The pressure-bonding film is inserted between the arbitrary leaf pieces in the above-described manner. The material of the paper sheet is not limited to normal paper, and various sheets in a wide range of fields such as synthetic paper, plastic film, sheet, and cloth can be used.

  The paper sheet conveying means, paper sheet folding means, pressure-bonding film supply means, paper sheet pressure-bonding means, and paper sheet cutting means are not particularly limited, and conventionally known ones may be used. . The paper sheet cutting means is for cutting a paper sheet in a state in which a long pressure-bonded film is inserted between both leaf pieces of each paper sheet into a predetermined size. Each leaf piece is also cut. The paper sheet into which the pressure-bonding film has been inserted may be provided to a paper sheet cutting means via a paper sheet pressure bonding means, if necessary, or may be subjected to paper sheet pressure bonding via a paper sheet cutting means. It may be provided to means.

  Moreover, as a support plate used for the said crimping | compression-bonding film insertion means, as long as it has the intensity | strength and flatness suitable for mounting a crimping film on an upper surface as mentioned above, and inserting between both leaf pieces. For example, each material such as metal, plastic, ceramic, or a composite of these materials may be used. For the vertical movement of the support plate, for example, a structure capable of swinging via a support shaft can be suitably employed. If the support plate is formed of stainless steel or other ferromagnetic metal or a composite of these metals and other materials, as the support plate driving means, for example, the electromagnet is demagnetized and excited to move the support plate up and down. Such a simple mechanism can be employed. Further, in the case where the support plate can swing through the support shaft as described above, as the support plate driving means, for example, a mechanism that rotates the support shaft so that the support plate can swing is provided. It may be adopted.

  As the paper sheet feeding means in the pressure-bonding film inserting means, for example, the paper sheet transporting means for transporting folded paper sheets to the intersection area between the paper sheet transporting path and the pressure-sensitive film supply path. The paper sheet conveying means and the paper sheet moving means for further moving the paper sheet fed to a certain extent to the final position may be used in cooperation with each other. The paper sheet moving means may be a mechanism that presses the rear end of the folded paper sheet to a predetermined position by swinging the bar by a predetermined angle via a support shaft, for example.

  Further, as the support plate extraction means in the pressure-bonding film insertion means, for example, a notch portion is drilled in the support plate and a pair of feed rollers are arranged opposite to each other above and below the support plate via the notch portion, In the crossing area, the paper sheet in which the support plate and the pressure-bonding film are completely inserted between the both leaf pieces is clamped by the pair of feed rollers from the upper and lower surfaces thereof, and is driven downstream of the crossing area by the rotational drive of the feed roller. Accordingly, the paper sheet is left in the crossing area and is conveyed from the crossing area so that the support plate is not subjected to the pinching pressure and the conveyance force by the feed roller due to the notch portion. A configuration may be adopted in which only the pressure-bonding film is inserted between the two leaf pieces.

  The hypotenuse may be formed in the edge part of the support plate in the opening part side of both leaf pieces. This hypotenuse has the effect of causing a wedge action on the upper leaf piece to open it upward and forcibly opening between both leaf pieces as the paper sheet feeding means operates. There are no particular restrictions on the shape or formation of the hypotenuse. The hypotenuse may be formed, for example, in a straight section or a curved section, or may be formed by mixing them, and the hypotenuse is inserted between both leaf pieces of the support plate. It may be extended upward or downward from the edge portion on the side. In addition, the oblique side may be formed integrally with the edge portion of the support plate, or may be formed by another member attached to the edge portion of the support plate, for example, another member having a wedge-shaped cross section. In addition to the constituent material of the support plate, other materials may be employed. As the separate member, for example, metal, plastic, ceramic, paper, cloth, synthetic paper or the like can be used.

  Further, the edge portion where the hypotenuse is formed is adjacent to the rear side of the hypotenuse, and a step, edge, bending, etc. that guides the margin portion on the side to be inserted between the two leaf pieces in the pressure-bonding film is formed. In that case, positioning of the pressure-bonding film with respect to the support plate can be performed manually and surely by the above-mentioned contact. It should be noted that the hit may not exceed the height of the upper surface of the pressure-bonded film to be guided.

As described above, the oblique side is extended above the edge portion of the support plate on the side to be inserted between the two leaf pieces, or is further inserted between the two leaf pieces in the pressure-bonding film placed on the support plate. If it is extended upward from the edge part on the other side, there is a difference in height between the top part of the oblique side and the edge part of the support plate or the edge part of the pressure-bonding film. The hit can be easily formed. In addition, in order to prevent danger due to the sharp tip of the hypotenuse at the edge portion of the support plate and to prevent damage to the paper sheet, the tip of the hypotenuse is within the range that does not hinder the intended effect of the hypotenuse. , Chamfering, rounding or a combination thereof may be performed.
The edge portion of the support plate may be further curved upward.

  As the lifting means for the support plate, for example, a push rod is disposed below the support plate, and the push rod is driven so that the support plate can be lifted by driving means such as electromagnetic means such as a solenoid or mechanical means. In the case where the support plate can swing through the support shaft as described above, the support shaft is driven to rotate so that the support plate can be raised, or the function of the support plate driving means described above is supported by the support plate. It is possible to adopt an extension of the so that it can be raised.

As a paper sheet cutting means for cutting the paper sheet into which the pressure-bonding film is inserted into a predetermined size, for example, a known rotary cutter can be suitably used. The boundary of the paper sheet flowing along the edge from the upstream side may be cut by a single cutting, or a slight width before and after the boundary may be cut twice. The narrow chips generated during the cutting are preferably free-falling downward, but they adhere closely to the back surface of the rotary blade due to static electricity or adhesive adhesion caused by continuous operation, and in subsequent cutting Involved in the machine causes an accident such as misalignment of the cutting position, poor cutting, and stoppage of the rotary cutter. Therefore, in order to prevent such a situation, it is only necessary to prevent chips from directly contacting the back surface of the rotary blade on the fixed blade side. As a method for this, if a plate-like elastic body is attached at an angle from the center of the back of the rotary blade to at least the position in contact with the fixed blade, a space is created between the back of the rotary blade and the plate-like elastic body. Then, since the plate-like elastic body is bent, the chip is bounced off by the restoring force.
The material of the elastic body (not necessarily elastic body) is not limited, and can be selected from a wide range of known fields such as plastic resin, paper, synthetic paper, cloth, ceramic, metal foil and mixed materials. It is. Further, it may be coated with an antistatic tape material, or a material kneaded with such a material may be used.
As the paper sheet cutting means, a known guillotine type cutting means can be used in addition to the rotary cutter.

  Further, as a means for discharging the chips without any delay, wind may be blown from the upstream side to the gap between the rotary blade and the fixed blade of the rotary cutter to forcibly discharge the chips. At that time, it is effective if the wind is sent to the flow tracing the falling route of the chips, and further effect can be expected if the wind is mixed with ions for eliminating static electricity.

  According to the means for inserting the pressure-sensitive film in the pressure-sensitive paper sheet manufacturing apparatus of the present invention, the support plate pushes down the edge portion of the lower leaf piece because the openings of both leaf pieces are directed upward with respect to the support plate. And the opening part of both leaf pieces opens large reliably. Thereby, conveyance to the said cross | intersection area | region with the crimping | compression-bonding film supply path of both folded leaf pieces becomes very easy. In addition, when the sheet is conveyed continuously to the intersection at a high speed, the opening is surely large, and jamming due to the pressure-bonding film and the leaf pieces is eliminated. Therefore, even an amateur can easily manufacture a pressure-sensitive paper sheet without producing a defective product.

Embodiments of the present invention will be described based on examples with reference to the drawings.

It is. FIG. 9 is a view similar to FIG. 2B for explaining the positional relationship between the paper sheet and the pressure-bonding film in the state where the edge portion on the opening side of the upper leaf piece is undulated in the pressure-bonding film insertion means using the support plate. FIG. FIGS. 10A, 10B, and 10C are conceptual side views of the main part for explaining the paper sheet cutting means by the rotary cutter over time.

  As shown in FIG. 1, in a pressure-sensitive paper sheet manufacturing apparatus for cut paper to which pressure-bonding film insertion means using a support plate can be applied, cut paper-like paper sheets P are stacked and accommodated in the stocker 11 of the supply unit 10. A plurality of leaf pieces Pa and Pb are connected to each paper sheet P via a fold line Pc (not necessarily displayed but may be replaced by a perforation or the like). Each of the paper sheets P is sequentially fed out of the stocker 11 by a feed roller 21 constituting a part of a series of paper sheet conveying means 20 and enters a predetermined paper sheet conveying path 22 indicated by an upper left arrow. A folding roller 31 constituting the paper sheet folding means 30 is folded in half along a fold line Pc and further downstream along a predetermined paper sheet conveyance path 23 indicated by an arrow in the upper left direction. It is conveyed to.

  On the other hand, an elongate pressure-bonding film F including a two-layer transparent film bonded in a peelable manner and having an adhesive layer that generates adhesiveness on the front and back surfaces by pressure or heating and pressure is a pressure-sensitive film. The film is sequentially supplied from a film roll 41 constituting the supply means 40 along a predetermined pressure-bonded film supply path 42 indicated by an arrow in the upper right direction.

  The paper sheet P folded by the paper sheet folding means 30 is conveyed to an intersection area 24 between the paper sheet conveying path 23 and the pressure-bonding film supply path 42 downstream from the paper sheet folding means 30. In the intersection area 24, it is provided to the pressure-bonding film insertion means 50 as shown in detail in FIGS.

  In the pressure-bonding film insertion means 50, as shown in FIGS. 2A and 2B, a support plate 51 made of a ferromagnetic material is moved up and down via a support shaft 52 in the same direction as the pressure-bonding film supply path. As shown in FIGS. 3 (A) and 3 (B), an electromagnet 54 constituting the support plate driving means 53 is installed below the support 51, and is further supported by FIGS. As shown in B), a rectangular notch 51a is formed in the support plate 51, and two pairs of feed rollers 56 and 57 constituting the support plate extraction means 55 are provided above and below the support plate 51, respectively. In this case, the upper feed roller 56 can swing up and down with respect to the lower feed roller 57 via the support member 58.

  In the crossing region 24, as shown in FIGS. 2 (A) and 2 (B), the elongate pressure-bonding film F is placed on the upper surface of the support plate 51 and the pressure-bonding film supply path indicated by the arrow in the upper right direction. 42, while the paper sheet P folded in half is indicated by an arrow in the upper left direction at a substantially right angle to the pressure-bonding film supply path 42 with the opening side at the top. It is transported along the similar transport path 23.

  The paper sheet P conveyed to the intersecting area 24 is moved by the paper sheet folding means 30 to a lower leaf piece Pb lower than the upper leaf piece Pa as shown in FIG. 2 (A), FIG. 3 (A) and the like. Is folded so as to be slightly longer, and in the crossing region 24, the position shown in FIG. 3A, that is, the upper leaf piece Pa is disposed upstream from the support plate 51 and the edge portion of the lower leaf piece Pb is located. At a position where Pbx slightly enters below the edge portion 51x of the support plate 51, the conveyance is temporarily stopped with the opening of both leaf pieces facing upward with respect to the support plate 51 by the action of the guide 8 or the like.

  In this state, as shown in FIG. 3 (B), the support plate 51 is attracted downward by the excitation operation of the electromagnet 54 in the support plate driving means 53 installed in the lower portion thereof, and rightward with the support shaft 52 as the center. When swinging clockwise as indicated by the downward arcuate arrow, the edge portion 51x of the support plate 51 descends and at the same time, the edge portion Pbx of the lower leaf piece Pb is pressed and pushed down by the support plate 51, thereby being folded. The upper and lower leaf pieces Pa and Pb of the paper sheet P are forcibly opened. Particularly, the edge portion Pax of the upper leaf piece Pa is warped upward by the action of the guide 8 and is sufficient to sandwich the support plate. In addition to forming a wide opening, it can be fed in such a way that it rides on the edge of the pressure-bonded film F placed on the support plate 51 without being caught.

  At this time, for example, when a paper sheet with irregularities deformed on its surface as shown in FIG. 9 is fed in a state where the upper leaf piece Pa is not lifted up, the opening edge is in a wavy state. The part may abut against the edge of the support plate, or it may catch on the pressure-sensitive film on the support plate and frequently cause accidents such as jamming.

  In this state, as shown in FIG. 9C, the paper sheet P having an opening between both the leaf pieces Pa and Pb serves as a paper sheet conveying means that also serves as a front stage of the paper sheet feeding means 60. The pressure-bonding film F is placed by a feed bar (not shown) and a pressing bar 63 pivotally attached to a support shaft 61 up to a stopper 62, which constitutes a subsequent stage of the paper sheet feeding means 60. When the sheet is further fed in the direction indicated by the left arrow toward the support plate 51, the support plate 51 and the pressure-bonding film F begin to be simultaneously inserted between the leaf pieces Pa and Pb, and finally, FIG. As shown in FIG. 2, when the inner portion of the folding line Pc of the paper sheet P reaches a position where it abuts against the tip of the edge portion 51x of the support plate 51, the feeding of the paper sheet P is stopped and the support plate 51 is stopped. Of paper sheet P and pressure-bonding film F against Me-decided is completed.

  As described above, the paper sheet P in which the support plate 51 and the pressure-bonding film F are inserted between both the leaf pieces Pa and Pb is then paired with the pair of support plate extraction means 55 as shown in FIGS. While being pinched by the feed rollers 56 and 57, the feed rollers 56 and 57 are driven to rotate to the downstream of the crossing region 24, during which the paper sheet P is transferred as shown in FIGS. 6A and 6B. As shown in FIG. 3, the support plate 51 is not subjected to the pinching drive by the feed rollers 56 and 57 due to the notch 51a, so that only the pressure-bonding film F is inserted between the leaf pieces Pa and Pb. In this state, as shown in FIG. 7, the sheet is conveyed along the downstream cord and leaf conveyance path 25 indicated by the arrow in the upper right direction from the intersection area 24, and as shown in FIG. It is used for the steps after the means 70.

  As shown in FIG. 1, the paper sheet P that has passed through the pressure-bonding film inserting means 50 is shown with an arrow in the upper right direction from the crossing area 24 as shown in FIG. A pressure-sensitive film F that is conveyed along the downstream paper sheet conveyance paths 25 and 26 shown in FIG. 1 and that is sandwiched between the paper sheet P by a heat panel 71 and a pressure roller 72 that constitute the paper sheet pressure-bonding means 70; Are integrated in a peelable manner.

The paper sheet P that has passed through the pressure roller 72 is fed into the gap between the rotary blade 1 and the fixed blade 2 of the rotary cutter, which is an example of the paper sheet cutting means 80 (see FIG. 10A). Is cut into the rear edge (ground side) of the paper sheet P that has been cut into the front edge (top side) in the traveling direction, and is finished into a single pressure-bonded paper sheet Q, and then The front edge (top side) of the paper sheet P fed from upstream is rotated counterclockwise by the support shaft 3 and cut by the contact 4 (see FIG. 10B). A narrow chip 5 formed from the top and bottom of each of the pressure-bonded paper sheets Q and the paper sheets P generated at this time is a chip discharging structure provided on the back surface of the rotary blade 1 as shown in FIG. 6 is reliably dropped and eliminated by the extrusion action.
As the means for discharging the chips 5, the wind that traces the natural fall route of the chips 5 from the gap between the rotary blade 1 and the fixed blade 2 is blown or blown as shown in the section of the paper sheet cutting means 80 in FIG. Forcibly feeding the chips 5 may be promoted by a fan.
In this way, postcards and other press-bonded paper sheets Q are manufactured.

In addition, this invention is not limited to the said Example.
For example, as shown in FIG. 8, a support plate 51 having an edge portion 51x with a hypotenuse 51y may be used, and the lower leaf piece Pb of the paper sheet P conveyed to the intersecting area 24 is supported. Prior to reaching the plate 51, the edge portion 51x of the support plate 51 may be temporarily raised by the support plate lifting means 65 so that the lower portion of the support plate is opened widely when necessary.

  That is, as shown in FIG. 8A, the folded paper sheet P is conveyed to the intersection area 24, and the lower leaf piece Pb of the paper sheet P is supported as shown in FIG. Before reaching the field 51, the push rod 67 is raised by the excitation operation of the solenoid 66 that constitutes the support plate lifting means 65, and the push rod 67 causes the support plate 51 to be centered on the support shaft 52. The edge portion 51x formed with the hypotenuse 51y is temporarily raised to the position of the upper limit stopper 69 by being swung counterclockwise as indicated by the arcuate arrow in the upper left direction from the position 68. Even if the edge portion Pbx is curved upward, the lower leaf piece Pb of the paper sheet P can easily go under the wide open portion of the edge portion 51x of the support plate 51 in the next step. The figure ( ), The push rod 67 is lowered by the demagnetizing operation of the solenoid 66 in the support plate lifting means 65, and at the same time, the edge portion Pbx of the lower leaf piece Pb is pushed down as the support plate 51 is lowered by the support plate driving means 53. Therefore, in the next step, as shown in FIG. 4D, the paper sheet P is transferred to the paper sheet feeding means 60 described above [FIGS. 3C and 3D]. As described above, as the pressure-bonding film F is fed toward the support plate 51 on which the pressure-bonding film F is placed, the support plate 51 and the pressure-bonding film F are smoothly inserted between the leaf pieces Pa and Pb using the wedge action of the oblique side 51y. Will be done.

  In the above embodiment, the paper sheet P is folded and forced upward by the guide 8 having an elliptical cross section as a means for arranging the paper sheet P so as to face the support plate in front of the support plate 51. The shape of the guide 8 is not limited, and may be any shape as long as it gives resistance upward so as to force upward. Further, the guide 8 is not necessarily required. For example, the guide 8 may be extended so that the direction in which the guide 8 is folded and drawn out is not in the horizontal direction but is slightly upward from the lower side in the direction toward the upper side with respect to the support plate 51. .
