Description

[Technical field]

[0001] The present invention relates to a slitter unit for cutting the ends of information paper that is peelably overlapped with an adhesive film, and to a manufacturing device for overlapped information paper that includes this slitter unit. [Background technology]

[0002] For example, when mailing documents containing personal information such as invoices and usage statements, envelope or postcard-sized overlapping information paper is used to prevent the personal information from leaking. The overlapping information paper is information paper in which the surfaces on which personal information such as invoices are printed are overlapped in a peelable manner using glue or adhesive film, and by making it postcard-sized, it has the advantage of being able to reduce mailing costs compared to envelopes. Furthermore, overlapping information paper using an adhesive film is made by overlapping the adhesive film on top of printed paper, so there is no risk of tampering with the information printed on the paper, and there is also the advantage that the adhesive film gives the paper a glossy appearance. In addition, because an adhesive film is used, the paper is less likely to be damaged even when wet by rain, and has excellent durability.

[0003] Such overlapped information paper is also known as one that is folded in thirds (see, for example, Patent Document 1). When manufacturing overlapped information paper folded in thirds, conventionally, a sprocket hole is formed in one end (long side) of a long strip of information paper, and sprocket teeth are inserted into the sprocket hole. Then, while rotating the sprocket to move the information paper forward, the information paper is folded in thirds along the longitudinal direction, and the end where the sprocket hole is formed (hole-forming end) is cut.

[0004] [Patent Document 1] JP 2001-232977 A Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, when cutting off the hole-forming end, two disk-shaped cutters are used to pinch and cut the vicinity of the hole-forming end. That is, as shown in Fig. 10, overlapping information paper 100B is overlapped with first piece of paper 101, second piece of paper 102, and third piece of paper 103 from the top, and fold 101a between first piece of paper 101 and second piece of paper 102 is close to the free end of third piece of paper 103, and hole-forming end 104 is adjacent to this free end.

[0006] When trying to cut the vicinity of hole-forming end 104 by pinching it from above and below with cutters, there is a risk of cutting fold 101a (to avoid cutting it), so hole-forming end 104 is cut on the outside, slightly away from fold 101a. This causes free edge 103a (the cut edge) of third piece of paper 103 to protrude outward beyond fold 101a, which could mar the appearance or cause problems in handling it as mail.

[0007] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a slitter unit and manufacturing apparatus for overlapping information paper that makes it possible to prevent the cut edge obtained by cutting off the hole-forming end from protruding outward from the fold. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the invention described in claim 1 is a slitter unit for cutting off the hole-forming end, which is the part where the sprocket holes are formed, when a sprocket hole is formed at one end of a long, strip-shaped information paper and the information paper is folded in thirds along the longitudinal direction to produce a stacked information paper, the slitter unit being characterized in that it comprises a clamping body having two clamping plates arranged opposite each other with a gap therebetween, into which the hole-forming end is inserted, and a cutter arranged on one of the clamping plates of the clamping body, with a blade tip protruding into the gap to cut off the hole-forming end.

[0009] The invention described in claim 2 is characterized in that, in the slitter unit described in claim 1, it is provided with a pressing portion provided in the gap of the clamping body and pressing the hole forming end portion toward the cutter.

[0012] The invention recited in claim 5 is characterized in that, in the slitter unit recited in claim 1, the slitter unit further comprises mounting means for detachably mounting the slitter unit to a manufacturing device for manufacturing the overlapped information paper.

[0013] The invention described in claim 6 is the slitter unit described in claim 1, characterized in that the cutter is disk-shaped and further includes a drive source for rotating the cutter.

[0014] The invention described in claim 7 is an apparatus for manufacturing overlapped information paper, in which a sprocket hole is formed at one end extending in the longitudinal direction of a long, strip-shaped information paper, and the information paper is folded in thirds along the longitudinal direction to produce overlapped information paper, the apparatus comprising: a folding stage for supplying a temporary adhesive film between the overlapping information paper while folding the information paper in thirds; a cutting stage for cutting the information paper folded in thirds in a short length direction; and a bonding stage for temporarily bonding the information paper cut in the short length direction, and a slitter unit for cutting the hole-forming end, which is the part where the sprocket hole is formed, is provided between the folding stage and the cutting stage, the slitter unit comprising a clamping body having two clamping plates arranged opposite to each other with a gap therebetween, into which the hole-forming end is inserted, and a cutter arranged on one of the clamping plates of the clamping body, the cutting edge of which protrudes into the gap to cut the hole-forming end. Effect of the Invention

[0015] According to the invention described in claim 1, the hole forming end is inserted into the gap between two clamping plates, and the hole forming end is cut with a cutter from one of the clamping plates. This makes it possible to cut the hole forming end at a desired or arbitrary position without the cutter coming into contact with any part of the information paper other than the hole forming end. This makes it possible to prevent the cut edge of the hole forming end from protruding outward from the fold of the overlapping information papers.

[0016] According to the invention described in claim 2, the hole-forming end is pressed toward the cutter by the pressing portion, so that the hole-forming end can be stably and reliably cut with the cutter while being clamped between the pressing portion and the cutter.

[0017] According to the invention described in claim 3, the hole-forming end portion is guided into the gap of the clamping body by the insertion guide portion, so that the hole-forming end portion can be stably and smoothly inserted into the gap of the clamping body, thereby enabling stable cutting to be continued.

[0018] According to the invention described in claim 4, the cut hole-forming end is guided in a desired direction by the discharge guide section. Therefore, by guiding the cut hole-forming end in a desired direction, it is possible to smoothly and appropriately collect and dispose of the hole-forming end and process the information paper.

[0019] According to the invention described in claim 5, the slitter unit can be attached and detached to the overlapped information paper manufacturing equipment using the mounting means, making it possible to easily attach the slitter unit to existing / off-the-shelf manufacturing equipment and adjust its position.

[0020] According to the invention described in claim 6, the slitter unit is provided with a drive source that rotates the disk-shaped cutter, so that the hole-forming end can be cut off simply by attaching the slitter unit to existing / ready-made manufacturing equipment (even if the manufacturing equipment does not have a drive source).

[0021] According to the invention described in claim 7, the overlapped information paper manufacturing device is provided with a clamp and cutter similar to claim 1, so it is possible to prevent the cut edge from cutting off the hole-forming end from protruding outward from the fold of the overlapped information paper, similar to the invention described in claim 1. Also, because the hole-forming end is cut between the folding stage and the cutting stage, it is possible to cut off the unnecessary hole-forming end after folding the information paper and to properly process it in the cutting stage or gluing stage.

[0023] Hereinafter, the present invention will be described based on the illustrated embodiment.

[0024] 1 to 9 show an embodiment of the present invention. FIG. 1 is a perspective view showing a slitter unit (slitter unit for stacked information sheets) 1 according to this embodiment with guide sheets 6 and 7 removed. FIG. 2 shows a front view (a), a left side view (b), a right side view (c), and a 1 and 2. FIG. 2 is a plan view (d) of the slitter unit 1. The slitter unit 1 is a device for cutting off the hole forming end 104, which is the portion where the sprocket holes (small holes) 104a are formed, when manufacturing the overlapped information paper 100A, and is attached to a manufacturing device (manufacturing device for overlapped information paper) 10, as described below.

[0025] First, the overlapped information paper 100A will be described. In this embodiment, the overlapped information paper 100A will be described as a postcard. The overlapped information paper 100A is manufactured by folding a long strip-shaped information paper 110 as shown in FIG. 3 in thirds along the longitudinal direction (fold line L1) and cutting it in the short direction (cut line L2). At this time, a temporary adhesive film (120 in FIG. 5) is interposed between the overlapping pieces of information paper 110, so that the overlapped information paper 100A is temporarily held in the third folded state and the overlapped information paper 100A can be opened by hand. This configuration is similar to that of conventional overlapped information paper.

[0026] Meanwhile, one end of the information paper 110 extending in the longitudinal direction is formed with a sprocket hole 104a, and as shown in Figure 4, the information paper 110 is folded in thirds excluding the hole-forming end 104 where the sprocket hole 104a is formed. In this state, the first piece of paper 101, the second piece of paper 102, and the third piece of paper 103 overlap from the top, and the fold 101a between the first piece of paper 101 and the second piece of paper 102 is close to the free end of the third piece of paper 103, and the hole-forming end 104 is adjacent to this free end.

[0027] The slitter unit 1 then cuts (cuts off) the hole-forming end 104 so that the free edge (cut edge) 103a of the third piece of paper 103 does not protrude outward beyond the fold 101a. The slitter unit 1 mainly comprises a clamping body 2, a cutter 3, a motor (driving source) 4, an attachment (attaching means) 5, a first guide sheet 6, and a second guide sheet 7.

[0028] The clamping body 2 is provided with two clamping plates 21 and 22 arranged facing each other with a gap 2a (apart), and the hole forming end 104 is inserted into the gap 2a. That is, as shown in Figs. 1 and 2, the clamping body 2 includes a frame 23 having a horizontal portion 231 and a vertical portion 232 formed by bending a substantially rectangular plate material into a substantially L-shape, and a substantially rectangular mounting plate portion 233 extending substantially vertically (substantially perpendicular to the surface of the vertical portion 232) from the lower surface (the surface on the side opposite the vertical portion 232) of the horizontal portion 231. The clamping plates 21 and 22 are substantially the same shape, and are flat plates with claw portions 21a protruding from both ends of one side of the substantially rectangular shape, as shown in Fig. 1(b). The two clamping plates 21 and 22 face each other so as to overlap, and are attached to the frame 23 so as to sandwich the end of the horizontal portion 231 of the frame 23 between the claw portions 21a, forming a gap 2a corresponding to the thickness of the horizontal portion 231.

[0029] Here, the size of the gap 2a is set so that the hole forming end 104 can be inserted reliably and appropriately with the guide sheets 6 and 7, which will be described later, attached. Here, the information paper 110 and the hole forming end 104 are arranged so that their surfaces extend substantially horizontally on the feed table 11 (see FIG. 5) of the manufacturing device 10, and therefore, as will be described later, the two clamping plates 21 and 22 are also arranged so that their surfaces extend substantially horizontally. At this time, the clamping plate 21 is located above the hole forming end 104, and the clamping plate 22 is located below the hole forming end 104. In addition, the two clamping plates 21 and 22 are formed with slits (long, thin cutouts) 2b to avoid interference with the cutter 3.

[0030] In this embodiment, the cutter 3 is disposed on the side of the clamping plate 22 under the clamping body 2, that is, on the side of the mounting plate portion 233 of the frame 23, and is a blade that rotates in a disk shape to cut the hole forming end portion 104. That is, a rotating shaft 31 is disposed which penetrates the mounting plate portion 233 of the frame 23 and extends to the clamping body 2 side, and the cutter 3 is attached to the end of the rotating shaft 31 on the clamping body 2 side. Currently, they are installed in the facility.

[0031] The cutter 3 is disposed so that its cutting edge protrudes into the gap 2a through the slit 2b of the clamping body 2 and can continuously cut the hole-forming end 104 inserted into the gap 2a of the clamping body 2. In other words, the cutting edge of the cutter 3 is disposed so as to extend in the longitudinal direction of the information paper 110, i.e., the hole-forming end 104.

[0032] Further, a motor (electric motor) 4 for rotating the cutter 3 is attached to the underside of the cutter 3 on the mounting plate portion 233 of the frame 23, and a drive shaft 41 of the motor 4 passes through the mounting plate portion 233. A drive belt 43 is hung between a first pulley 32 attached to the end of the rotation shaft 31 of the cutter 3 on the side opposite to the clamping body 2, and a second pulley 42 attached to the drive shaft 41 of the motor 4. As a result, when the drive shaft 41 of the motor 4 rotates, the rotation shaft 31 and the cutter 3 rotate via the drive belt 43.

[0033] The fixture 5 is for detachably mounting the slitter unit 1 to the manufacturing apparatus 10, and includes a fixture body 51 and mounting screws 52. The fixture body 51 is a block body having a U-shaped cross section, and includes two horizontal mounting portions 511 extending substantially horizontally and a vertical mounting portion 512 extending substantially vertically, and is attached to the upper end side (opposite the horizontal portion 231 side) of the vertical portion 232 of the frame 23 at the vertical mounting portion 512.

[0034] 2(b), the mounting fixture body 51 is attached so that the direction of the opening (opening direction) of the two mounting horizontal parts 511 extends toward the cutting edge of the cutter 3. Furthermore, two long holes 232a extending in the longitudinal direction (up-down direction) are formed in the vertical part 232 of the frame 23, and bolts 53 inserted into the long holes 232a are screwed into the screw holes of the mounting fixture body 51. Then, by moving the bolts 53 along the long holes 232a, the positional relationship between the mounting fixture 5 and the cutter 3, that is, the position and height of the cutter 3 in the manufacturing apparatus 10, can be adjusted.

[0035] The mounting screw 52 is a knobbed bolt that penetrates and is screwed into the horizontal mounting portion 511 on the upper side (opposite the cutter 3 side) of the fixture body 51. As shown in Figs. 5 and 6, the mounting bar 131 extending in a direction substantially perpendicular to the longitudinal direction of the manufacturing apparatus 10 (information paper 110) is inserted between the horizontal mounting portions 511 of the fixture body 51, and the mounting screw 52 is tightened, so that the slitter unit 1 is attached to the manufacturing apparatus 10. The mounting screw 52 can be loosened to remove the slitter unit 1 from the manufacturing apparatus 10 or to adjust its position. Here, when the slitter unit 1 is attached to the manufacturing apparatus 10, the vertical portion 232 of the frame 23 faces the insertion direction F of the hole forming end 104.

[0036] Here, the mounting bar 131 has a substantially circular cross section, and the upper portion (the portion facing the mounting screw 52) is formed flat (D-cut). This allows the mounting fixture 5 to not rotate around the axis of the mounting bar 131, and allows the slitter unit 1 to be properly positioned (so that the cutter 3 is positioned directly below the hole forming end 104). In this manner, in this embodiment, the hole forming end 104 is cut from the bottom surface side of the information paper 110, but it may also be cut from the top surface side.

[0037] The first guide sheet 6 is a sheet provided in the gap 2a of the clamping body 2, and has both a pressing section 61 for pressing the hole-forming end 104 toward the cutter 3, and a discharge guide section 62 for guiding the cut (separated) hole-forming end 104 in a desired direction. That is, it is a substantially band-shaped elastic resin sheet, and as shown in Figs. 7 and 8, a central section 63 is fixed to the upper surface of the clamping plate 21 on the upper side (mounting fixture 5 side) of the clamping body 2. One end portion, ie, a pressing portion 61 , is bent from the vertical portion 232 side of the frame 23 and disposed in the gap 2 a of the clamping body 2 .

[0038] This pressing portion 61 is not fixed, and bends toward the cutter 3 due to its own weight and elastic force, thereby pressing the hole forming end 104 inserted into the gap 2a toward the cutter 3. In addition, the vertical portion 232 side of the frame 23, that is, the portion facing the insertion direction F of the hole forming end 104, is bent and gently curved, so that the hole forming end 104 can be easily inserted into the gap 2a.

[0039] Here, the width of the pressing portion 61 and the central portion 63 (the length in the width direction of the information paper 110) is approximately the same dimension as the width of the clamping plates 21, 22, and is set so as to cover the entire width of the hole forming end 104 and the portion of the information paper 110 adjacent to the hole forming end 104. Also, a slit similar to the slit 2b of the clamping body 2 is formed in the portion of the pressing portion 61 facing the cutter 3.

[0040] Meanwhile, the discharge guide portion 62, which is the other end of the first guide sheet 6, extends downstream (downstream of the cutter 3) in the insertion direction F of the hole forming end portion 104 and curves gently downward. The width of this discharge guide portion 62 is set to cover only the entire width of the hole forming end portion 104. This allows the hole forming end portion 104 cut off by the cutter 3 to be guided downward (in a desired direction), that is, in a direction different from that of the information paper 110 from which the hole forming end portion 104 was cut off. Thus, in this embodiment, the hole forming end portion 104 is guided downward, but it may be guided in another direction (for example, upward) depending on the structure of the manufacturing device 10 and the convenience of waste disposal.

[0041] The second guide sheet 7 is provided on the clamping body 2, and is a sheet having an insertion guide portion 71 that guides the hole forming end portion 104 into the gap 2a of the clamping body 2. That is, it is a substantially rectangular elastic resin sheet, and as shown in Figs. 7 and 8, one approximately half portion 72 is fixed (attached) to the upper surface of the clamping plate 22 on the lower side (the cutter 3 side) of the clamping body 2, and the other approximately half portion, the insertion guide portion 71, extends so as to face the insertion direction F of the hole forming end portion 104.

[0042] The insertion guide portion 71 is slightly curved downward due to its own weight and elasticity. The width of the second guide sheet 7 is set to be approximately the same as the width of the clamping plates 21, 22, and is set to cover the entire width of the hole-forming end 104 and the portion of the information paper 110 adjacent to the hole-forming end 104. This makes it easier for the hole-forming end 104 and its adjacent portion to be inserted into the gap 2a of the clamping body 2 by the insertion guide portion 71. A slit similar to the slit 2b of the clamping body 2 is formed in the portion of one of the approximately half portions 72 facing the cutter 3. In this way, the hole-forming end 104 and its adjacent portion are inserted and transferred into the gap 2a of the clamping body 2 while being clamped by the resin guide sheets 6, 7, and are cut by the cutter 3.

[0043] Next, a state in which the slitter unit 1 having such a configuration is attached to the manufacturing apparatus 10 and its operation will be described.

[0044] Here, the manufacturing apparatus 10 has a basic configuration similar to that of conventional apparatus, so a detailed description will be omitted, but the manufacturing apparatus 10 is roughly configured as follows. That is, as shown in Fig. 5, a folding stage 12, a cutting stage 13, and a bonding stage 14 are mainly arranged in a long straight line. First, the sprocket 12A is rotated while inserting and engaging the teeth of the sprocket 12A with the sprocket holes 104a of the information paper 110, and the information paper 110 is fed on the feed table 11 in sequence to each of the stages 12, 13, and 14.

[0045] Then, in the folding stage 12, the information paper 110 is folded in thirds along the longitudinal direction while the temporary adhesive film 120 is supplied between the overlapping pieces of information paper 110. At this time, the temporary adhesive film 120 is supplied and inserted between the first piece of paper 101 and the second piece of paper 102, and between the second piece of paper 102 and the third piece of paper 103.

[0046] Next, in the cutting stage 13, the information paper 110 folded in three is cut in the short dimension. That is, as shown in Figures 5 and 6, a cylindrical cutting drum 132 equipped with multiple horizontal blades on its outer periphery is disposed so that its axis extends substantially horizontally and crosses the feed table 11 substantially vertically. Then, as this cutting drum 132 rotates, it cuts the information paper 110 in the short dimension (along the cutting line L2 in Figure 3).

[0047] Next, the information paper 110 cut in the short length direction is temporarily adhered in the adhesion stage 14. That is, the adhesion stage 14 is equipped with a plurality of heated heat plates, and the information paper 110 is passed between these heat plates, so that the temporary adhesive film 120 adheres to the pieces of paper 101, 102, and 103 of the information paper 110. As a result, the information paper 110 is temporarily adhered via the temporary adhesive film 120 to become the overlapped information paper 100A. Thereafter, the overlapped information paper 100A is stacked in the stacking section 15.

[0048] The slitter unit 1 is attached between the bending stage 12 and the cutting stage 13 of the manufacturing apparatus 10. That is, as described above, it is attached via the mounting fixture 5 to the mounting bar 131 disposed between the sprocket 12A and the cutting drum 132. In addition, the power terminal of the motor 4 is connected to a power plug provided in the manufacturing apparatus 10 to drive and rotate the motor 4 and the cutter 3.

[0049] Then, when information paper 110 folded in thirds by folding stage 12 is sent, it is guided by insertion guide portion 71 of second guide sheet 7, and hole forming end 104 and part of third piece of paper 103 are inserted into gap 2a of clamping body 2, as shown in Figures 6, 9, etc. Meanwhile, first piece of paper 101 and second piece of paper 102 are positioned on the upper and outer sides of clamping body 2.

[0050] Next, the cutter 3 separates the hole-forming end 104 from the third piece of paper 103. At this time, the pressing portion 61 of the first guide sheet 6 presses the hole-forming end 104 and the third piece of paper 103 toward the cutter 3 while cutting the hole-forming end 104. Furthermore, the separated hole-forming end 104 is guided downward by the discharge guide portion 62 of the first guide sheet 6.

[0051] Then, the information paper 110 from which the hole-forming end 104 has been cut is cut at the cutting stage 13 as described above, and temporarily adhered at the adhesion stage 14. Such steps and processing are performed sequentially and continuously on the long information paper 110.

[0052] As described above, with the slitter unit 1 and manufacturing device 10, with the hole forming end 104 inserted into the gap 2a between the two clamping plates 21, 22, the cutter 3 cuts the hole forming end 104 from the side of the one or lower clamping plate 22. This makes it possible to cut the hole forming end 104 at a desired or arbitrary position without the cutter 3 coming into contact with any part of the information paper 110 other than the hole forming end 104. This makes it possible to prevent the cut edge 103a obtained by cutting off the hole forming end 104 from protruding outward from the fold 101a of the overlapped information paper 100A.

[0053] In addition, the hole forming end 104 is pressed toward the cutter 3 by the pressing portion 61 of the first guide sheet 6, so that the hole forming end 104 is sandwiched between the pressing portion 61 and the cutter 3. In this state, it becomes possible to cut the hole forming end 104 with the cutter 3 stably and reliably.

[0054] In addition, since the hole forming end 104 is guided and guided into the gap 2a of the clamping body 2 by the insertion guide portion 71 of the second guide sheet 7, the hole forming end 104 can be stably and smoothly inserted into the gap 2a of the clamping body 2, making it possible to continue stable cutting.

[0055] Furthermore, the cut hole-forming end 104 is guided downward (in a direction different from that of the information paper 110 from which the hole-forming end 104 was cut off) by the discharge guide portion 62 of the first guide sheet 6. This makes it possible to smoothly and appropriately collect and dispose of the hole-forming end 104 and process the information paper 110.

[0056] Furthermore, since the slitter unit 1 can be attached to and detached from the manufacturing equipment 10 by the fixture 5, the slitter unit 1 can be easily attached to an existing / off-the-shelf manufacturing equipment 10 and its position can be easily adjusted.

[0057] Furthermore, since the slitter unit 1 is equipped with a motor 4 that rotates the cutter 3, it is possible to cut off the hole forming end 104 simply by attaching the slitter unit 1 to an existing / ready-made manufacturing equipment 10 (without the need to provide a driving source in the manufacturing equipment 10).

[0058] In addition, since the hole forming end 104 is cut between the folding stage 12 and the cutting stage 13, it is possible to cut off unnecessary hole forming end 104 after folding the information paper 110 and perform appropriate processing at the cutting stage 13 or the adhesive stage 14.

[0059] Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there are design changes within the scope of the present invention, they are included in the present invention. For example, in the above embodiment, the overlapped information paper 100A is a postcard, but it may be other information paper. Also, the cutter 3 is a disc-shaped rotating cutter, but it may be a cutter with other shapes and forms (cutting methods). [Explanation of symbols]
