Description

PRESS-FITTED FILM INSERTING MEANS OF PRESS-FITTED PAPER MANUFACTURING EQUIPMENT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressed paper sheet manufacturing apparatus using cut paper sheets for producing compressed paper sheets usable in direct mail, postcards, reciprocating postcards, envelopes, and the like. In detail, although the external appearance is a normal direct mail, a postcard, a reciprocal postcard, an envelope, etc., since the paper sheets folded in multiple layers are press-laminated so as to be peeled off through the press film, it is difficult to conceal a large amount of information therein. The present invention relates to a compressed film inserting means in a compressed paper sheet manufacturing apparatus for producing possible compressed paper sheets from cut paper sheets.

In recent years, as postal items such as postcards, a plurality of leaf pieces on which information is displayed are folded together, and at the same time, the leaf pieces facing each other are detachably bonded to each other so that a large amount of information can be transmitted. Compressed paper is used a lot.

As an apparatus for manufacturing compressed paper as described above, for example, Japanese Patent Application Laid-Open No. 5-38894 and Japanese Patent Application Laid-Open No. 9-76665 include a plurality of paper sheets formed by connecting a plurality of leaf pieces through a folding line. Paper conveyance means for conveying sequentially from the paper feeding unit according to a predetermined paper conveyance path, paper sheet folding means for folding each paper sheet on the paper conveyance path, and two layers of transparent film detachably bonded to each other. And a pressurized film supply means for sequentially supplying a long press-shaped press film formed by pressing or heating and pressurizing an adhesive layer formed on the front and back sides according to a predetermined press film supply path, and a paper sheet folding means. Compression film that inserts the compression film between arbitrary leaf pieces of the folded paper sheets that face each other at the intersection of the downstream paper conveyance path and the compressed film supply path. Paper sheet pressing means for bonding between the inserting means and both leaf pieces of the paper sheet in which the compressed film is inserted on the paper conveying path downstream from the pressing film inserting means so as to be peeled off through the pressing film under pressure or heating and pressing. And a paper sheet cutting means for cutting the paper sheets into which a compressed film is inserted to a predetermined size on a paper sheet conveying path upstream or downstream from the paper sheet pressing means.

The compressed paper sheets obtained by the above-mentioned manufacturing apparatus are peeled from each other between the two compressed pieces of the compressed sheets as described above, thereby peeling between the two transparent films of the compressed film sandwiched between these laminated sheets, thereby making the compressed paper sheets. At the same time, the transparent film is coated on the information display surface of each leaf piece, and the information on each leaf piece passes through the transparent film and is developed in a state that can be visually confirmed.

In the press leaf paper, the information on each leaf piece cannot be visually confirmed from the outside until it is released from the recipient side, so it is excellent in confidentiality such as privacy protection, and much larger amount of information is usually compared with the letter of the leaf. Because the data can be sent at a fee, the transmission cost for the amount of information is greatly reduced, and since the information on each leaf is covered with a transparent film, it is excellent in information preservation, water resistance, and contamination resistance, and gives aesthetic appearance to the information. It can also achieve effects such as promotion of advertising and promotion of advertisement.

However, any of the above manufacturing apparatuses is generally mass-produced and suitable for use in notifications sent by a large company such as mail-order sales or correspondence education to a large number of members. When the large-scale manufacturing apparatus as described above is used, the manufacturing cost of the compressed paper sheets is extremely high, and it is difficult to cope with the production of a small lot.

In particular, in the compressed paper sheet manufacturing apparatus disclosed in Japanese Patent Laid-Open No. 5-38894, since continuous foam paper is used as the paper sheet, a dedicated continuous foam printer is required for printing the paper sheet. At home and the like, there is a problem that a printer generally used for output of a personal computer cannot cope with printing of the continuous foam paper.

Further, in the compressed paper sheet manufacturing apparatus disclosed in Japanese Patent Application Laid-open No. Hei 9-76665, since the non-continuous cut paper conveyed one by one as paper sheets is used, the above-mentioned problem regarding the printing of paper sheets is solved, but this production In the compressed film inserting means in the apparatus, during the folding of conveyed paper sheets, a difficult task of continuously inserting the compressed film at the same speed as the paper sheets is continuously inserted between the leaf pieces facing each other. It was to.

On the other hand, the invention relating to the compressed paper sheet manufacturing apparatus using cut paper-like paper sheets, which has a particularly simple structure and can be miniaturized by improving the inserting means of the compressed film between the leaf pieces of the paper sheets, has been cooperated with by the present applicant. It is completed by L Engineering Co., Ltd., and is filed on May 2, 2002 as Japanese Patent Application No. 2001-296979. In addition, this patent application is currently shared between JDL Engineering Co., Ltd. and KDK Co., Ltd. which is the present applicant.

The compressed film inserting means in the compressed paper sheet manufacturing apparatus according to Japanese Patent Application No. 2001-296979 is movable up and down at the intersection of the paper sheet conveying path and the compressed film supply path downstream from the paper sheet folding means. And a support plate on which the compressed film supplied on the upper surface is placed on the upper surface, and vertical support of the support plate is installed, and the paper sheets folded so that the lower lobe is slightly longer than the upper lobe are conveyed to the intersection. When the upper lobe of the paper sheet is disposed upstream of the support plate and the lower lobe is disposed below the support plate, the support plate is lowered integrally with the press film, and at the same time, the lower leaf piece is pushed down to force the two pieces together. Pressing film is placed on the support plate driving means and the paper sheet between the two leaf pieces Paper sheet sending means for sending the support plate and the compressed film simultaneously between both the leaf pieces and at the same time sent to the finger plate, and at the same time, while removing only the support plate from the paper sheet inserted between the leaf plate and the support film Thereby, there is practically a need for a support plate removing means in which paper sheets are inserted only between the pieces of paper.

Embodiment of the Invention

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, in contrast with the basic technology before improvement.

(1) Overall construction of compressed paper sheets manufacturing apparatus using cut paper sheets

As a compressed paper sheet manufacturing apparatus using cut paper sheets, to which a crimp film inserting means using a supporting plate is applicable, as shown in FIG. 6, the cut paper sheets are formed on the stocker 11 of the paper feed section 10. The stream P is accommodated, and the sheets P are connected to each of the leaf pieces P through the folding line Pc. Each of the paper sheets P is released from the stocker 11 in turn by the feed rollers 21 which constitute a part of the series of paper sheet conveying means 20 and is shown by an arrow in the upper left direction. It is conveyed downstream along the predetermined paper sheet conveying path 22, is folded in two by the folding roller 31 which comprises the paper sheet folding means 30, and is shown by the arrow of the left upward direction. It continues to be conveyed downstream along the predetermined paper sheet conveying path 23.

On the other hand, the elongated self-adhesive film F, which comprises two layers of transparent films bonded to each other so as to be peelable and an adhesive layer is formed on the surface and the back by pressing or heating and pressing, is a compressed film. From the film roll 41 which comprises the supply means 40, it supplies sequentially in accordance with the predetermined | prescribed pressurized film supply path 42 shown with the arrow of the upper right direction.

The paper sheet P folded by the paper sheet folding means 30 has an intersection point 24 between the paper sheet conveying path 23 and the compressed film feed passage 42 downstream from the paper sheet folding means 30. At the same time, it is supplied to the crimping film inserting means 50 as shown in Figs. 7A and 7B to 12 at the same time.

The paper sheets P passing through the crimping film inserting means 50 are, in the state where the crimping film F is inserted between both leaf pieces Pa and Pb, as shown in FIG. The heat panel 71 and the pressure roller 72 which are conveyed along the downstream paper conveyance paths 25 and 26 shown by the arrow of the upper right direction from 24, and comprise the paper sheet crimping means 70. And the cutter 81 constituting the paper sheet cutting means 80, thereby producing a postcard or other compressed paper sheets Q.

(2) Basic configuration and function of press film insertion means using support plate

In the compressed film inserting means 50, as shown in Figs. 7A and 7B, the support plate 51 made of a ferromagnetic material is moved up and down through the support shaft 52 in the same direction as the compressed film supply path 42. An electromagnet 54 constituting the support plate driving means 53 is provided below the support plate 51 while being supported while being allowed to swing, and as shown in FIGS. 8A and 8B, and in FIGS. 9A and 9B. As shown in the drawing, two feed rollers 56 and 57 which form a support plate extracting means 55 at the same time as a rectangular cutout 51a is provided in the support plate 51 and are installed above and below the support plate 51. Are arranged facing each other through the cutout 51a, and in that case, the upper feed roller 56 swings up and down with respect to the lower feed roller 57 through the supporting member 58. It is possible.

At the intersection point 24, as shown in Figs. 7A and 7B, a long press-shaped film F is placed on the surface of the support plate 51, and is shown by the arrow in the upper right direction. The paper sheets P, which are sequentially folded along the supply path 42, are folded in two, and the left side of the paper sheet P is opened at the open side, and is substantially perpendicular to the compressed film supply path 42. It is conveyed along the paper conveyance path 23 shown.

The paper sheet P conveyed to the intersection point 24 is, by the paper sheet folding means 30, as shown in 7A, 8A, or the like, as shown in 7A, 8A, etc., the leaf piece Pb lower than the upper leaf piece Pa. Is folded to be slightly longer, and at the intersection point 24, the position shown in Fig. 8A, i.e., the upper lobe Pa, is disposed upstream of the support plate 51, and the edge of the lower lobe Pb. The conveyance is once stopped at a position where the portion Pbx enters slightly below the edge portion 51x of the support plate 51.

In the above state, as shown in Fig. 8B, the support plate 51 is sucked downward by the excitation operation of the electromagnet 54 in the support plate driving means 53 provided at the bottom thereof. When rocking in the clockwise direction shown by an arc-shaped arrow in the lower right direction about the support shaft 52, the edge portion 51x of the support plate 51 descends and the edge portion Pbx of the lower lobe Pb. ) Is also pushed down by this support plate 51, thereby forcibly opening between the upper and lower lobes Pa, Pb of the folded paper sheets P. In the above state, as shown in Fig. 8C, the paper sheet P, which has opened between both pieces Pa and Pb, serves as a paper sheet conveying means that also serves as a front end of the paper sheet sending means 60. The pressing film 63 is pivotally attached to the support shaft 61 to the stopper 62 so that the roller (not shown) and the paper sheet sending means 60 can be pivoted to the stopper 62. When F is continuously sent toward the support plate 51 on which the F is placed, in the direction shown by the arrow on the left side, the support plate 51 and the pressing film F are simultaneously inserted between the two leaf pieces Pa and Pb. Finally, as shown in FIG. 8D, at the portion where the inner portion of the folding line Pc of the paper sheet P reaches a position almost in contact with the front end of the edge portion 51x of the support plate 51, The feeding of the paper sheets P is stopped and at the same time the paper sheets P and the compressed film F with respect to the support plate 51 The value determined is completed.

As described above, the paper sheets P in which the support plate 51 and the compressed film F are inserted between the two leaf pieces Pa and Pb are continuously supported as shown in FIGS. 10A and 10B to 12. While being pushed by a pair of feed rollers 56 and 57 of the extracting means 55, the feed rollers 56 and 57 are conveyed downstream by the intersecting point 24 by rotational driving of the feed rollers 56 and 57, and in the meantime, As shown in Figs. 11A and 11B, the paper sheet P is such that the supporting plate 51 is not subjected to the push-in driving by the feed rollers 56 and 57 because of the cutout 51a. With only the compressed film F inserted between the two pieces Pa and Pb, as shown in FIG. 12, the paper sheet conveying path downstream shown by the arrow to the upper right direction from the intersection point 24 is shown. While conveying according to (25), as shown in FIG. 6, it is supplied to the process below the paper sheet pressing means 70. As shown in FIG.

(3) Problems of the pressing film inserting means using the support plate

In the crimp film insertion means 50 using the support plate 51 as described above, the edges Pax of the flanks of the upper leaves Pa of the paper sheets P are shown in FIGS. 7A and 7B and FIGS. 8A and 8B. As shown in FIG. 8C, when the film is substantially flat and has a certain degree of elasticity and is in a nearly straight state without being stretched down, the insertion of the compressed film F between the two leaf pieces Pa and Pb is shown in FIG. 8C. And smoothly without problems in the order as shown in 8D.

However, in the case where the paper sheet P has an extreme curl as shown in Fig. 13 in accordance with the printing process or the like, resulting in irregularities on the surface, at the intersection point 24, the upper leaf piece ( This paper sheet P is disposed at an upstream side in front of the supporting plate 51 and at a position where the edge portion Pbx of the lower leaf piece Pb slightly enters the lower portion of the edge portion 51x of the supporting plate 51. ), Once the conveyance is stopped, the edge portion Pax of the upper leaf piece Pa is waved as shown in FIG. 13, and is lowered toward the lower leaf piece Pb as shown in FIG. 14A. In the following step, even if the support plate 51 is lowered by the support plate driving means 53 and the edge portion Pbx of the lower leaf piece Pb is pushed down by the support plate 51, the folded paper sheet Between the upper and lower lobes Pa and Pb of the stream P as shown in FIG. 14B In the next step, the paper sheet P, in which the gap between the leaf pieces Pa and Pb is incomplete, cannot be opened sufficiently by the paper sheet sending means 60 (see Figs. 8C and 8D). Even if the press film F is sent toward the support plate 51 on which the press film F is placed, in the direction shown by the arrow on the left side, the support plate 51 on which the press film F is placed is between the two pieces Pa and Pb. The upper lobe Pa is pulled from the lower edge Pax to the edge Fx of the crimp film F, as shown in FIG. 14C, without being inserted into the edge smoothly. At the same time, it hides between the crimping film F and the support plate 51 from this edge part Pax, or in some cases, it hides under the support plate 51, and as a result, they block the paper (jamming ( jamming)}.

(4) Pressing film inserting means according to the first aspect, which solves the above problem

In the crimp film insertion means 501 according to the first aspect of the present invention, as shown in Figs. 1A to 1C, the edge portion 51x of the side inserted between the both leaf pieces Pa and Pb in the support plate 51 is shown. At the same time, it is inclined downward toward its front end and substantially acute at the front end thereof, at the same time extending above the edge portion 51x of the support plate 51 and further placed on the support plate 51. In the compressed film F to be placed, a quadrangle 51y having a cross-sectional linear shape extending upward from the edge portion Fx of the side inserted between the two leaf pieces Pa and Pb forms a cross-sectional arrow shape. In the portion 51x, a stepped contact portion for guiding the edge portion Fx of the side inserted between the leaf pieces Pa and Pb in the crimp film F is adjacent to the rear of the quadrilateral 51y. 51b) is formed.

That is, in the case where the paper sheets P having curled surfaces and irregularities on the surface are used in the crimping film inserting means 501 using the supporting plate 51 of the above configuration, at the intersection point 24 At the position where the upper lobe Pa is placed upstream of the support plate 51 and the edge Pbx of the lower lobe Pb is slightly below the edge 51x of the support plate 51. When the paper sheet P has stopped the conveyance once, as shown to FIG. 1A, the edge part Pax of the upper leaf piece Pa will hang down toward the lower leaf piece Pb, and In the process, as shown in Fig. 1B, even if the edge portion Pbx of the lower leaf piece Pb is pushed down by the support plate 51 lowered by the support plate drive means 53, both leaf pieces Pa , Pb) is not completely opened. However, in the next step, as shown in Fig. 1C, the paper sheet P is placed with the compressed film F by the paper sheet sending means 60 (see Figs. 8C and 8D) already described. As it is sent toward the support plate 51, the quadrilateral 51y of the support plate 51 enters between the incompletely opened lobes Pa and Pb from the front end of the acute angle, and the quadrilateral generated at that time ( By the wedge action of 51y), the upper lobe Pa slides over the quadrilateral 51y of the support plate 51 from its edge portion Pax, and at the same time, compresses over the top portion of the quadrilateral 51y. Ride to the upper surface of the film (F), thereby forcibly open between the two pieces (Pa, Pb) and smoothly insert the support plate 51 and the compressed film (F) between the two pieces (Pa, Pb). It becomes.

As the support plate 51 usable in the crimp film inserting means 501 according to the first aspect, as shown in Figs. 1A to 1C, Figs. 2A, and 2E to 2G, a cross-sectional arrow in which a cross section 51y having a linear cross section is formed. 2B to 2D, and having an edge portion 51x in the shape of a cross-section arrow formed with a cross section 51y having a cross-sectional curve shape, as shown in FIGS. 2B to 2D.

In the support plate 51 shown in Figs. 2A to 2G, as shown in Figs. 1A to 1C, each side 51y is inserted between the two leaf pieces Pa and Pb in the support plate 51. Steps extending upward from the edge portion 51x and capable of guiding the edge portion Fx of the crimp film F adjacent to the rear portion 51y of each edge portion 51x thereof are adjacent thereto. The contact part 51b of a shape or a bending shape is formed. In the support plate 51 shown in FIG. 2D, a quadrangle 51y extending downward from the edge portion 51x is formed. In the supporting plate 51 shown in Fig. 2E, a separate member 59 having a cross-sectional wedge shape is attached to the edge portion 51x, and at the same time, the top portion of the quadrangle 51y is an edge portion (to the separate member 59). 51x) is formed to extend to the upper surface. In the support plate 51 shown in FIG. 2F, chamfering and / or curvature processing are performed at the front end forming the acute angle of the quadrangle 51 at the edge portion 51x of the cross-sectional arrow shape shown in FIG. 2A. In the support plate 51 shown in FIG. 2G, in the edge portion 51x of the cross-sectional arrow shape shown in FIG. 2A, the top portion of the quadrangle 51 extends to the upper surface of the edge portion 51x.

Although not shown, in the support plate 51 shown in Figs. 2A to 2G, improvements have been made so that each quadrangle 51y does not extend above the edge portion 51x of the support plate 51. Needless to say, it can be used for the crimp film inserting means 501.

(5) Second problem of press film inserting means using support plate

As described above, the edge portion Pax of the upper leaf piece Pa in the paper sheet P hangs down as shown in FIG. 14A, and the edge of the lower leaf piece Pb is supported by the support plate driving means 53. Even when the portion Pbx is pushed down, the support plate cannot be completely opened between the two pieces Pa and Pb as shown in Fig. 14B, and finally, the support plate is jammed (jamming). This is solved by forming a quadrangle 51y as shown in Figs. 1A to 1C and Figs. 2A to 2G on the edge portion 51x of 51. Figs.

However, when the paper sheet P is conveyed to the intersection point 24 in a state where the edge portion Pbx of the lower leaf piece Pb is curved upward by a curl generated by a printing process, The edge portion Pbx of the lower lobe Pb does not enter the lower portion of the support plate 51 as scheduled as shown in Fig. 1A, and as shown in Fig. 15, the quadrilateral of the edge portion of this support plate 51 is shown. 51y), a situation arises of riding up, and as a result, it becomes impossible to push down the edge portion Pbx of the lower leaf piece Pb by the support plate driving means 53, and at the same time, paper jamming occurs.

(6) crimping film insertion means according to a second aspect which solves the second problem.

In the crimping film inserting means 502 according to the second aspect, as shown in Figs. 3A to 3C, the edge portion 51x in which the quadrangle 5y of the shape and structure as shown in Figs. 1A to 1C is formed, The support plate 51 is bent upward with respect to the main body, whereby the bottom of the support plate 51 is widened.

That is, in the crimp film insertion means 502 using the support plate 51 of the above configuration, when the folded paper sheets P are conveyed to the intersection point 24, as shown in FIG. 3A, these paper sheets The lower lobe Pb of (P) easily hides to the wide open bottom of the curved edge portion 51x upwardly of the support plate 51, even if the edge portion Pbx is curved upward, for example. By this, in the next step, as shown in Fig. 3B, the pushing down of the edge portion Pbx of the lower leaf piece Pb by the lowering of the supporting plate 51 by the supporting plate driving means 53 is performed as usual, and thus In the next step, the paper sheet P, as shown in Fig. 3C, is supported by the paper sheet sending means 60 (see Figs. 8C and 8D), on which the press film F is placed. As it is sent toward 51, about the 1st form mentioned above In the same form as the compressed film inserting means 50, the support plate 51 and the compressed film F are smoothly inserted between the two leaf pieces Pa and Pb using the wedge action of the quadrangle 51y. do.

As the support plate 51 usable in the crimp film inserting means 502 according to the second aspect, as shown in Figs. 4A to 4E, an edge portion 51x in which each quadrangle 51y shown in Figs. 2A to 2E is formed. ) Is curved upward in a cross-sectional linear shape, as shown in Fig. 4F, the edge portion 51x having a quadrangle 51y formed in Fig. 2A is curved upward in a cross-sectional curve shape, and As shown in Fig. 4G, the edge portion 51x having the quadrangle 51y formed in Fig. 2A is curved in a cross-sectional linear shape in two steps upward, as shown in Fig. 4H. The edge part 51x in which the edge part 51x in which the quadrangle 51y which does not extend above the part 51x was formed was curved upward in cross-sectional linear shape, etc. are mentioned. In the support plate 51 shown in FIG. 4H, the bent portion formed by the bending of the edge portion 51x is used as the contact portion 51b capable of guiding the edge portion Fx of the crimp film F, if necessary. Used. Although not shown, the edge portion 51x formed with the quadrangle 51y shown in Figs. 2F and 2G is curved upward in cross-sectional linear shape or cross-sectional curve shape, and the like in the crimp film inserting means 502. Needless to say.

(7) crimping film insertion means according to a third aspect, which solves the second problem.

In the crimp film insertion means 503 according to the third aspect, as shown in Figs. 5A to 5D, the support plate on which the edge portion 51x has a quadrangle 51y of the shape and structure as shown in Figs. 1A to 1C is formed. In the same configuration as the crimping film inserting means 501 using 51, before the lower leaf piece Pb of the paper sheet P conveyed to the intersection point 24 reaches the support plate 51, The edge portion 51x in which the quadrilateral 51y is formed in the support plate 51 is temporarily raised by the support plate lifting means 65, thereby widening the lower side of the support plate 51 widely when necessary.

That is, in the crimp film insertion means 503 using the support plate 51 of the above configuration, as shown in FIG. 5A, the folded paper sheets P are conveyed to the intersection point 24, and shown in FIG. 5B. As described above, before the lower leaf piece Pb of the paper sheet P reaches the support plate 51, by excitation of the solenoid 66 constituting the support plate lifting means 65. Push rod 67 is raised, and by this push rod 67, the said support plate 51 moves to the arc-shaped arrow of the upper left direction from the position of the stopper 68 which centered around the support shaft 52. While swinging in the counterclockwise direction shown, the edge portion 51x on which the quadrangle 51y is formed is temporarily raised upward to the position of the upper limit stopper 69, whereby the paper sheet P The lower lobe Pb is supported even if its edge Pbx is curved upward, for example. The element of the solenoid 66 in the support plate lifting means 65 can be easily hidden in the wide open bottom of the edge portion 51x of the plate 51, as shown in FIG. 5C in the next step. By the operation, the push rod 67 is lowered, and at the same time, the pushing down of the edge portion Pbx of the lower leaf piece Pb in accordance with the lowering of the support plate 51 by the support plate driving means 53 is performed as usual, Therefore, in the next step, the paper sheet P is placed on the paper sheet P by means of the paper sheet sending means 60 (see FIGS. 8C and 8D) described above, as shown in FIG. 5D. As it is sent toward the support plate 51, in the same form as the crimping film inserting means 501 according to the first aspect described above, between the two leaf pieces Pa and Pb using the wedge action of the quadrangle 51y. Insertion of the support plate 51 and the pressing film (F) of the will be performed smoothly .

In the crimp film inserting means 503, not only the support plate 51 used for the crimp film inserting means 501 described above, but also the support plate 51 used for the crimp film inserting means 502 described above are also suitable. It can be adopted.

It is to be noted that the above is merely illustrative of preferred embodiments of the present invention according to the accompanying drawings for the purpose of understanding the present invention, and that various changes and modifications can be made without departing from the spirit of the present invention. There is no.

The present inventors independently performed experiments under various conditions on the compressed film inserting means having the above structure. As the compressed film inserting means using a support plate, for example, paper sheets are used at the time of print processing. Depending on the type of printer used, the printing method, and the printing conditions, the printer may be subjected to high temperatures, causing extreme curls, and irregularities on the surface.As a result, the upper lobes may undulate from the folded paper sheets and lower lobes. In the case of sagging downward, the sliding of the lower lobe with the lowering of the supporting plate as described above does not sufficiently open the gap between the two lobes, so that the compressed film between the two lobes has already been described. We found a new problem that could not be inserted smoothly in the same form.

SUMMARY OF THE INVENTION In view of the above problems, the present invention has been made in the press sheet paper manufacturing apparatus using cut paper sheets, in which curls are generated during the printing process, and paper sheets having irregularities on the surface thereof are formed. Even in the case of use, the present invention provides a compressed film inserting means capable of smoothly inserting a compressed film between two pieces of folded paper sheets without occurrence of jamming or the like.

In the compressed paper sheet manufacturing apparatus according to the first aspect of the present invention, the compressed film inserting means includes a sheet-like paper sheet formed by joining a plurality of leaf pieces through a fold line from a sheet feeding section to a predetermined sheet conveying path. Paper sheet conveying means to be conveyed in turn, paper sheet folding means for folding each paper sheet on the paper conveying path, and two layers of transparent film which are peeled and adhered to each other. Supplying pressurized film supplying means for supplying an elongated self-shaped compressive film in which an adhesive layer is formed by means of adhesive according to a predetermined pressurizing film supply path, and a paper sheet conveying path and a pressurized film downstream from the paper sheet folding means. A crimp film inserting means for inserting a crimp film between arbitrary leaf pieces of the folded paper sheet which face each other at the intersection of the furnace, and crimping Paper sheet pressing means for adhering between the leaf pieces of the paper sheet in which the compressed film is inserted under the paper sheet conveying means lower than the sheet inserting means so as to be peeled off through the pressing film under pressure or heating and pressing; In the compressed film inserting means in the compressed paper sheet manufacturing apparatus comprising paper sheet cutting means for cutting the paper sheets into which the compressed film is inserted into a predetermined size on a paper conveyance path upstream or downstream of the means,

The support plate is installed to be movable up and down at the intersection point, the support plate on which the supplied compressed film is placed on the upper surface, and the paper sheet folded so that the lower leaf piece is slightly longer than the upper leaf piece is installed to enable the up and down driving of the support plate. When the upper lobe of this sheet is disposed upstream of the support plate and the lower lobe is disposed below the support plate while being conveyed to the intersection point, the support plate is lowered integrally with the press film, and at the same time, the lower leaf piece is thereby removed. The support sheet driving means pushed down and forced to open between the two leaf pieces, and the paper sheet between the two leaf pieces is directed toward the support plate on which the compressed film is placed, thereby simultaneously inserting the support plate and the compressed film between the leaf pieces. Between the sending means and both lobes, In the structure consisting of the support plate removing means for removing only the support plate from the inserted paper sheet, thereby allowing only the press film to be inserted between the leaf pieces.

It is characterized in that at the edge of the side inserted between the two leaf pieces in the supporting plate, a quadrilateral is inclined downward in the front end direction and substantially acutely formed at the front end thereof.

According to the above configuration, as the paper sheet sending means is directed toward the support plate on which the compressed film is placed, the quadrilateral formed at the edge of the support plate is separated from the front end of the acute angle. Entering between the two lobes, the wedge action of the quadrilateral occurs at the time, so that the upper lobe slides over the quadrilateral of the support plate, and at the same time, the upper and lower lobes are forcibly opened, so that the support plate and the compression between the two lobes are pressed. The film is inserted smoothly.

In the above case, for example, the paper sheet is curled by the printing process, and the irregularities are formed on the surface, so that the upper leaf piece is stretched downward, so that even if the gap between the leaf pieces is incomplete even after the operation of the support plate driving means, The quadrilateral of the support plate easily enters between both incomplete flaps of the flank from the front end thereof, causing the wedge to act on the upper flanks, thereby opening them upward and forcibly opening them between the flanks.

In the above configuration, in the case where the quadrilateral extends above the edge portion of the side inserted between the both pieces of the support plate, it is particularly preferably inserted between the both pieces of the compressed film placed on the support plate. If it extends upward from the edge of the side, the wedge action of the quadrilateral causes the upper lobe to slide over the quadrilateral of the support plate, and at the same time, it is more likely to rise beyond the top of the quadrilateral to the upper surface of the compressed film. Therefore, the insertion of the support plate and the compressed film between both leaf pieces is made more smoothly.

As the cut paper-like paper sheet, which is useful for the pressing film inserting means, not only the simplest paper sheets formed by folding two contiguous leaf pieces in two, but also the three contiguous leaf pieces in a zigzag direction in a Z-shaped cross section. Fold in three directions or in three directions in a c-shaped cross section, or four or more leaflets connected together in a zigzag direction, folded in a zigzag direction, folded in one direction, and opened in a central direction from both sides. Paper sheets or the like formed by folding them into a form or a mixture of them can be used, and the compressed film is inserted in the above-described form between arbitrary leaf pieces facing each other for any paper sheet. Moreover, as a material of the said paper sheet, it is not limited to normal paper, Various sheets of various fields, such as a synthetic paper, a plastic film, a sheet, and a cloth, can be employ | adopted.

The paper sheet conveying means, the paper sheet folding means, the compressed film supplying means, the paper sheet pressing means, and the paper sheet cutting means are not particularly limited, and conventionally known ones may be used. The paper sheet cutting means cuts paper sheets in a state in which a long, compressed film is inserted between the leaf pieces of each paper sheet to a predetermined size, and not only the compressed film but also each leaf piece is cut as necessary. The paper sheet into which the compressed film is inserted may be supplied to the paper sheet cutting means through the paper sheet pressing means, or may be supplied to the paper sheet pressing means via the paper sheet cutting means.

In addition, the support plate used in the crimping film inserting means may be one having a strength and flatness suitable for inserting the crimping film on the upper surface and inserting it between the leaf pieces as described above, for example, such as metal, plastic, ceramic, etc. It may be formed from each material or a composite of these materials. As for the shanghai copper of the said support plate, the structure which can rock, for example through a support shaft can be employ | adopted suitably. When the support plate is formed of a metal of ferromagnetic material other than stainless steel or a composite of these metals and other materials, the support plate is driven, for example, by electromagnet element and excitation, and the support plate is moved up and down. A simple mechanism made to move can be adopted. 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 in which the support shaft is rotatably driven to swing the support plate may be employed.

As the paper sheet sending means in the crimping film inserting means, for example, the paper sheet conveying means for conveying the folded paper sheet to the intersection point of the paper sheet conveying path and the compressed film supplying path may be used. The paper sheet conveying means and the paper sheet moving means for further moving the paper sheets sent to some extent to the final position may be used in cooperation. The paper sheet moving means may be, for example, a mechanism that swings the bar by a predetermined angle through the support shaft and presses the rear end of the folded paper sheet to a predetermined position.

In addition, as the support plate removing means in the crimping film inserting means, for example, a cutout is installed in the support plate, and at the same time, a pair of feed rollers are disposed above and below the support plate to face each other through the cutout. At the point of intersection, the sheet of paper in which the support plate and the compressed film are completely inserted between the two pieces is inserted into the pair of feed rollers from the upper and lower surfaces thereof, and is conveyed downstream of the point of intersection by the rotational driving of the feed rollers. The support plate is not compressed and conveyed by the feed roller due to the incision, thereby remaining at the intersection and simultaneously compressing the paper conveyed from the intersection between the leaflets. You may employ | adopt the structure made to be in the inserted state.

The quadrilateral formed at the edge of the support plate is, as described above, according to the operation of the paper sheet sending means, wedging the upper lobe to open it upward and forcibly opening it between the two lobes. As long as there is no particular limitation on the shape, the form and the like. For example, the quadrilateral may be formed in a cross-sectional linear shape, may be formed in a cross-sectional curve shape, or may be formed in a mixed shape thereof, and this quadrilateral may be formed more than the edge portion of the side inserted between the two leaf pieces in the support plate. It may extend upwards or downwards. In addition, the said quadrilateral may be formed integrally with the edge part of a support plate, or may be formed by the other member attached to the edge part of a support plate, for example, another member of a wedge-shaped cross section, In addition to the constituent materials of the support plate, materials other than them may be employed. As said another member, a metal, plastic, a ceramic, paper, cloth, synthetic paper, etc. can be used, for example.

Furthermore, a contact portion such as a stepped shape, an edge shape, a curved shape, etc., which guides the edge portion of the side inserted between the two pieces of the compressed film adjacent to the rear portion of the quadrilateral, is formed on the edge portion where the quadrilateral is formed. It may be formed, and in that case, positioning of the crimping film with respect to the support plate can be made stable and secure by the contact portion. In addition, the contact portion does not interfere even if the height of the upper surface of the guide film is guided.

As described above, the quadrilateral extends upwardly from the edge portion of the side inserted between the two pieces of the support plate, or more than the edge portion of the side inserted between the two pieces of the compressed film placed on the support plate. In the case of extending upwards, a height difference occurs between the top portion of the quadrilateral and the edge portion of the support plate or the edge portion of the compressed film, so that the contact portion can be easily formed adjacent to the rear side of the quadrilateral. In addition, in order to prevent the danger caused by the front end of the acute angle of the quadrilateral at the edge of the support plate and to prevent damage such as paper sheets, the front end of the quadrilateral, Chamfering, curvature processing, or a combination thereof may be performed.

In the crimp film inserting means having the above-described configuration, as described above, a quadrilateral that is inclined downward in the front end direction of the support plate and substantially acutely formed at the front end thereof is formed at the edge of the support plate. Although it is possible to cope with the gap between the two lobes due to sagging down, for example, when the paper sheet is conveyed to the intersection with the curl of the printing process, the edge of the lower lobe is largely curved upward. As a result, the edge of the lower lobe does not enter the lower side of the support plate as scheduled, and therefore rises above the edge of the support plate and thus above the quadrilateral, and as a result, the lower lobe following the lowering of the support plate by the support plate driving means. The pushing itself becomes impossible, and then between the scheduled lobes A separate problem that the insertion of the holding plate and pressed films are also impossible remained.

The pressurized film inserting means in the press paper manufacturing apparatus which concerns on the 2nd aspect of this invention solves the said problem, Comprising: In the structure of the said pressurized film inserting means which uses the support plate in which the quadrilateral was formed in the edge part, The formed edge portion is bent upward with respect to the supporting plate body, thereby widening the lower side of the supporting plate.

According to the above configuration, when the folded paper sheet is conveyed to the intersection, the lower leaf piece of the paper sheet is easily moved to the wide open bottom portion of the curved portion upward of the support plate, even if the edge portion thereof is curved upward, for example. In this way, it becomes possible, as usual, to insert the support plate and the compressed film between both the leaf pieces using the wedge action of the quadrilateral following the pushing down of the lower leaf piece following the lowering of the support plate by the support plate driving means.

The edge portion in which the quadrilateral is formed in the support plate is not particularly limited as long as it can achieve the wedge action by this quadrangle and also allow the upper curved lower lobe to be hidden under the edge portion of the support plate. For example, the edge portion may be curved in a cross-sectional linear shape, may be curved in a cross-sectional curve shape, or may be curved in a mixed shape thereof.

The crimping film inserting means in the compressed paper sheet manufacturing apparatus according to the third aspect of the present invention is also in the state where the paper sheet is largely curved upward at the edge of the lower leaf piece by curl generated by the printing process. In order to solve the above-described problems caused when conveyed to the intersection, the lower leaf of the paper sheet conveyed to the intersection is characterized in that the compressed film inserting means uses a support plate having quadrilaterals formed at the edges. Before reaching the support plate, the edge portion in which the quadrilateral is formed in the support plate is temporarily raised by the support plate lifting means, thereby widening the bottom of the support plate wide when necessary.

According to the above configuration, when the folded paper sheet is conveyed to the intersection, the lower leaf piece of the paper sheet has a wide spread of the edge portion of the support plate raised by the support plate lifting means, even if the edge portion thereof is curved upward. It easily hides downwards, thereby enabling the insertion of the support plate and the compression film between both lobe pieces using the wedge action of the quadrilateral, followed by the pushing down of the lower leaf piece following the lowering of the support plate by the support plate driving means. .

As the support plate having a quadrilateral formed at the edge portion, one used for the crimping film inserting means according to the first aspect described above and one used for the crimping film inserting means according to the second aspect can be employed. In one case, since the edge portion curved upward from the support plate is further raised by the support plate lifting means, the lower part of the support plate can be spread wider with respect to the lower lobe of this paper conveyed to the intersection point. .

As the support plate lifting means, for example, a push rod is disposed below the support plate, and the push rod is driven by an electronic means such as a solenoid or a driving means such as a mechanical means. To allow the support plate to be driven up, to allow the support plate to rotate when the support plate can oscillate through the support shaft as described above, or to perform the function of the support plate driving means described above. What expanded the support plate so that extension may be possible, etc. can be employ | adopted.

As described above, the compressed film inserting means in the compressed paper sheet manufacturing apparatus according to the present invention is applied to the compressed paper sheet manufacturing apparatus using cut paper sheets, including direct mail from cut paper sheets. The present invention contributes to the production of compressed paper sheets which can be used for postcards, reciprocal postcards, envelopes, etc., and in which a large amount of information is concealed and can be peeled off and developed without the occurrence of jamming.
