Description

The present invention relates to a rotary cutter for continuously cutting, for example, continuously conveyed paper sheets. Furthermore, the present invention relates to a crimped paper sheet manufacturing apparatus using cut paper-like paper sheets for manufacturing crimped paper sheets that can be used for direct mail using the same, postcards, reciprocal postcards, sealed letters, and the like.
The pressure-sensitive paper sheet manufacturing apparatus is a pressure-bonding stack that allows paper sheets folded in multiple layers to be peeled off via a pressure-sensitive film, despite the appearance of ordinary direct mail, postcards, reciprocating postcards, sealed letters, etc. Therefore, the pressure-bonded paper sheets capable of concealing a large amount of information inside are manufactured from the 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.

  The above-mentioned pressure-sensitive paper sheet manufacturing apparatus according to Japanese Patent Application No. 2001-296979 discloses a predetermined paper sheet transport path from a paper feeding section for each cut paper sheet having a plurality of leaf pieces connected through a folding line. Paper sheet conveying means that sequentially conveys along the paper sheet, paper sheet folding means for folding each paper sheet on the paper sheet conveying path, and two layers of transparent films bonded in a peelable manner and pressurizing on the front and back surfaces Alternatively, a pressure-bonding film supply means for sequentially supplying a long pressure-bonded film formed with an adhesive layer that produces adhesiveness by heating and pressurization along a predetermined pressure-bonding film supply path, and downstream of the paper sheet folding means. A pressure-sensitive film insertion means for inserting a pressure-sensitive film between any opposing leaf pieces in the folded paper sheet, and a pressure-sensitive film insertion means. On the downstream paper sheet conveyance path, a paper sheet pressure bonding means for releasably bonding between both leaf pieces in the paper sheet into which the pressure bonding film is inserted under pressure or heating and pressure through the pressure bonding film; The paper sheet includes a paper sheet cutting means for cutting the paper sheet into which the pressure-bonding film is inserted into a predetermined size on the paper sheet conveyance path upstream or downstream of the paper sheet pressure bonding means. Specifically, a cutting means using a rotary cutter is disclosed as the cutting means.

  The present inventors include the paper sheet conveying means, the paper sheet folding means, the pressure film supply means, the pressure film insertion means, and the paper sheet that is detachably bonded via the pressure film under pressure or heating and pressure. After passing through the pressure bonding means, when a rotary cutter is used as the paper sheet cutting means to cut the top and bottom of the paper sheet into which the pressure-bonding film has been inserted to a predetermined size, It has been found that there is a new problem that it is not discharged well to the outside of the cutter, and therefore cannot be cut by being caught in the blade of the rotary cutter.

When a rotary cutter is used and, for example, continuously conveyed papers are cut with a short stroke, a phenomenon that chips having a slight width wrap around the back side of the rotary blade frequently occurs.
This is because paper sheets with a slight cutting width that are extremely light weight are attracted by the static electricity generated on the rotating blades, or stick to the back of the rotating blades when cutting sheets with adhesive or adhesive applied. This is caused by a slight amount of adhesive or adhesive residue.
The chips adhering to the back side of these rotary blades are caught in the cut paper sheets passing between the rotary blades and the fixed blades by the rotary operation of the rotary cutter, and the chips are simultaneously cut when cutting the paper sheets. Will do. However, such double cutting of paper sheets and chips causes more resistance than necessary when cutting with a cutter blade, so it may deviate from the planned cutting line, or may not be cut, or in severe cases the cutter blade It may happen that the cutting operation stops.
In view of such problems, the problem to be solved by the present invention is that, when adopting a paper cutting means by a rotary cutter, the chips are not discharged well, and are caught in the rotary cutter to cause a cut deviation or inability to cut. It is an object of the present invention to provide a rotary cutter that does not cause any troubles caused by chips in subsequent processes or a crimped paper sheet manufacturing apparatus for cut paper using the rotary cutter.

In order to achieve the above object, a rotary cutter according to the present invention is characterized by providing a chip removal structure in a rotary cutter that continuously cuts continuously conveyed paper.
Furthermore, the pressure-sensitive paper sheet manufacturing apparatus according to the present invention sequentially conveys each cut sheet-like paper sheet in which a plurality of leaf pieces are connected via a fold line from the paper feeding unit along a predetermined paper sheet conveyance path. It includes a paper sheet conveying means, a 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 pressurizing or heating and pressing the front and back surfaces A pressure-sensitive film supply means for sequentially supplying a long pressure-bonded film formed with an adhesive layer that generates adhesiveness along a predetermined pressure-sensitive film supply path, and a paper sheet conveying path downstream from the paper sheet folding means. And a pressure-sensitive film insertion means for inserting a pressure-sensitive film between any opposing leaf pieces in the folded paper sheet, and a paper sheet conveyance path downstream from the pressure-sensitive film insertion means Oh A paper sheet crimping means for releasably adhering between the two leaf pieces of the paper sheet into which the pressure-bonding film is inserted through the pressure-bonding film under pressure or heating and pressure, and upstream of the paper sheet crimping means. Or a downstream side of the paper sheet conveying path, wherein the apparatus is a pressure-sensitive paper sheet manufacturing apparatus for cut paper comprising a paper sheet cutting means for cutting the paper sheet into which the pressure-bonding film is inserted into a predetermined size. It is characterized in that the top-to-bottom direction of each paper sheet continuously conveyed in a side-by-side state by the paper sheet crimping means is cut with a rotary cutter provided with a chip removal structure on the back surface side of the rotary blade.

The cutting process of paper sheets by a rotary cutter will be described in detail.
1A is a front view of the rotary cutter R, and FIG. 1B is a side view. As shown in FIGS. 1A and 1B, the rotary cutter R includes a fixed blade 2 and a rotary blade 1. Then, as shown in FIG. 2B and FIG. 2, the paper sheet P is conveyed from the left direction in the figure. Subsequently, as shown in FIG. 4C, the leading end portion of the paper sheet P stopped at the position to be cut (contact point 4 between the fixed blade 2 and the rotary blade 1) is counterclockwise as shown in FIG. The rotary blade 1 and the fixed blade 2 that rotate around the blade 4 are cut at the contact point 4. After cutting, the rotary blade 1 rotates clockwise and returns to the original position shown in FIG. At that time, it is desired that the cut chips 5 are successfully dropped downward.
However, as the number of times of cutting increases, the adhesive or adhesive adheres to the back surface of the rotary blade 1 by cutting off static electricity accumulated, for example, a label with adhesive or adhesive, etc. Cases where the scraps 5 are in close contact frequently occur.
As shown in FIG. 3A, the chips 5 are in close contact with the back surface of the rotary blade 1 and are swung around while being in close contact with the back surface of the rotary blade 1 by the rotating operation of the rotary blade 1 as shown in FIG. And overlaps the paper sheet P conveyed from the upstream. Then, as shown in FIG. 5C, the rotary blade 1 cuts substantially two sheets in the next cutting, and if that part is defective or misaligned or severe, it becomes impossible to cut and stops. It will end up.

As a result of intensive studies, the present inventors have found that the disadvantages of the rotary cutter can be solved by providing a chip removal structure on the back surface of the rotary blade of the rotary cutter.
As this chip removal structure, for example, as shown in FIG. 4, a tongue-like structure 6 for providing a space where the chips 5 do not contact can be employed on the back surface of the rotary cutter R on the fixed blade 1 side. With such a structure, the chips 5 are already forcibly thrown down at the moment when the paper sheet P is cut at the contact point 4 as shown in FIGS. Therefore, it can be reliably dropped.

As shown in FIG. 6 (A), the chip removal structure may be formed over the entire back surface of the rotary blade 1 on the fixed blade 2 side, or as shown in FIG. 6 (B). You may form in only a required part.
In the case of the tongue-like structure, if an elastic material is selected, as shown in FIG. 4 (B), the rotary blade 1 is bent when it is cut at the contact point 4 with the fixed blade 2, so that it does not get in the way and is cut. Will not be adversely affected. However, it does not necessarily require elasticity. Further, as shown in FIG. 6 (C), a groove having a depth corresponding to the thickness of the tongue-like structure 6 is dug on the back surface of the rotary blade 1 so that the tongue-like structure does not interfere with the cutting. When the pressure is generated in contact with the blade, it may be hidden in the groove as indicated by an arrow in the figure so that the back surface of the rotary blade 1 does not have a step due to the tongue-like structure 1.
Metal, plastic resin, ceramic, paper, synthetic paper, cloth, or a composite of these materials can be used as the material of the velous structure, and preferably a material that does not accumulate static electricity, or an adhesive or adhesive is attached. A difficult material can be preferably used. Such materials can be used by adding an antistatic agent to the above-mentioned known materials, applying Teflon or fluorine treatment to the surface, or attaching a commercially available tape with antistatic or Teflon treatment to the surface. Doubles the effect of forcibly dropping trash.
The material of the object to be cut that is the subject of the present invention is not limited to ordinary paper, such as synthetic paper, plastic resin, metal foil, cloth (fiber), ceramic, and a mixture of them. Become a target.

In addition to the chip removal structure, there is a means for forcibly sending wind into the gap between the rotary blade 1 and the fixed blade 2 as shown in FIGS.
As a means for forcibly sending wind, for example, a fan 7 as shown in FIG. 6A is provided on the upstream side of the rotary cutter R, and similarly compressed air is blown with an air pump as shown in FIG. This is possible by providing the blow 8 for the purpose, but is not limited to that means. An effect can be further expected if the ion wind is preferably mixed with ions having static eliminating action, but this is not necessarily required.
Since the wind blown into the gap between the rotary blade 1 and the fixed blade 2 traces the dropping route of the chips 5, the chips 5 fall without stress.
A further chip removal effect can be expected by combining the means for forcibly sending wind and the belo-shaped structure.
The above-described chip removal mechanism can be used for paper sheet cutting means in a pressure-sensitive paper sheet manufacturing apparatus for cut paper, which will be described later.

According to the rotary cutter provided with the chip removing structure of the present invention, chips do not remain in close contact with the back surface of the rotary blade even in a cutting operation in which narrow chips are generated. Accordingly, there are no cutting defects or shifts due to chips, and further accidents such as inability to cut or cutter clogging are eliminated, so that the product quality is stabilized and the working efficiency is improved.
And if it uses the crimping paper sheet manufacturing apparatus for cut paper containing the rotary cutter provided with the chip | tip removal structure of this invention, it will become possible even for an amateur to manufacture a lot of pressing paper sheets easily.

In an embodiment of the present invention to be described later, as shown in FIGS. 4 and 6A, a rotary cutter R provided with a tongue-like structure 6 made of plastic resin on the back surface of the rotary blade 1 on the fixed blade 2 side is provided. used. The bottom surface of the tongue-like structure 6 is subjected to a Teflon tape coating process (not shown) in which a discharge substance is kneaded. The tongue-like structure 6 is slightly elastic as shown in FIG. 4 (B), and is set to a length that is slightly retracted from the contact point 4 so as not to disturb the cutting of the paper sheet P.
As described above, the rotary cutter R performs a rotational motion around the support shaft 3, but since this rotational motion is electrically controlled, various motions can be set. For example, when the paper sheet P is transported from the upstream side, it is possible to arbitrarily add an operation of once rotating clockwise to increase the gap so as to open the opening so as to be easily received.

  In the pressure-sensitive paper sheet manufacturing apparatus for cut paper including cutting means by a rotary cutter, cut paper-like paper sheets P are stacked and accommodated in the stocker 11 of the supply unit 10 as shown in FIG. A plurality of leaf pieces Pa and Pb are connected via a folding 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. 8A and 8B, a support plate 51 made of a ferromagnetic material is vertically moved through a support shaft 52 in the same direction as the pressure-bonding film supply path 42. As shown in FIGS. 9 (A) and 9 (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. 8A and 8B, 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 FIGS. 8A and 9A. Is folded so as to be slightly longer, and in the crossing region 24, the position shown in FIG. 9A, that is, the upper leaf piece Pa is arranged upstream of the support plate 51 and the edge portion of the lower leaf piece Pb is located. The conveyance is temporarily stopped at a position where Pbx slightly enters below the edge portion 51 x of the support plate 51.

  In the above state, as shown in FIG. 9B, 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 in the lower right direction around the support shaft 52. When rocking in the clockwise direction indicated by the arcuate arrow, the edge portion 51x of the support plate 51 is lowered, 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 folding the paper The upper and lower leaf pieces Pa and Pb of the leaf P are forcibly opened. In the above state, as shown in FIG. 9C, the paper sheet P having an opening between the both leaf pieces Pa and Pb is a feed roller as a paper sheet conveying means that also serves as a front stage of the paper sheet feeding means 60. (Illustration is omitted) and a support on which the pressure-bonding film F is placed by 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 51 is further fed in the direction indicated by the left-pointing arrow toward the plate 51, the support plate 51 and the pressure-bonding film F begin to be simultaneously inserted between the leaf pieces Pa and Pb. Finally, as shown in FIG. When the inner part of the folding line Pc of the leaf P reaches a position where it abuts on the tip of the edge portion 51x of the support plate 51, the feeding of the paper sheet P is stopped and the sheet P with respect to the support plate 51 Positioning of crimped film F 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, 57, the feed rollers 56, 57 are driven downstream by the rotation of the feed rollers 56, 57, during which the paper sheet P is transferred to FIGS. 12A and 12B. 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. As shown in FIG. 13, the sheet is conveyed along the downstream sheet conveyance path 25 indicated by the arrow in the upper right direction as shown in FIG. It is used for the steps after the means 70.

  As shown in FIG. 7, the paper sheet P that has passed through the pressure-bonding film insertion 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.

Then, 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 R as described above, and is fed first to the front edge in the advancing direction (the top side). ) Cuts the rear edge (ground side) of the paper sheet P that has already been cut to finish it into a single pressure-bonded paper sheet Q, and then the front edge of the paper sheet P fed from the upstream (the top) Side). The chips 5 having a narrow width on the top and the bottom of each of the pressure-bonded paper sheets Q and the paper sheets P generated at this time are blown from the gap between the rotary blade 1 and the fixed blade 2 (trace the natural fall route of the chips 5). ) It is surely dropped and eliminated by the wind of the blow 8 and the pushing action of the bevel-like structure 6.
In this way, postcards and other press-bonded paper sheets Q are manufactured.
