Abstract
Description
[Technical Field]
[0001] The present invention relates to a slitting device that cuts a wide web made of synthetic resin, paper, or fiber into a predetermined width using a slitting blade while it is moving, and a method for manufacturing a process-type information communication body that uses the slitting device to manufacture an information communication body by folding and releasably stacking multiple leaf pieces on which information is written. [Background technology]
[0002] Slitting methods used by slitters to divide and rewind a wide web as it travels include the razor cut method, which uses a cutting blade to cut grooves or cut in mid-air, the shear cut method, which uses two opposing rotating circular blades, upper and lower, to sandwich and cut the web, and a method in which the circular blades are pressed against a backup roller to cut the web as it passes between them.
[0003] Among the various cutting methods mentioned above, the backup roller cutting method is advantageous because it allows relatively free setting of the cutting position with few restrictions and the device is simple and can be made compact. One such device is the slitter blade positioning device disclosed in Japanese Patent Laid-Open Publication No. 8-155886. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 8-155886 Summary of the Invention [Problem to be solved by the invention]
[0005] The invention of the cited reference is a slitter that combines a backup roller and a slitting blade, and thus offers various advantages, such as the ability to cut any web material, a simple structure and operation, and the ability to freely adjust the slit width and position. However, difficulties arise when manufacturing information communication units, which are now widely used and comprise multiple leaflets connected via fold lines, folded and releasably stacked together. These difficulties become particularly pronounced when manufacturing information communication units that are to be unfolded into a bound state. Specifically, when folding multiple leaflets into a bound state, it is desirable to simultaneously remove the tabs on the throat side of the folded leaflets and perforate the pages of the throat side to facilitate smooth unfolding. However, if the distance between the slitter and the perforation is too narrow, this process becomes impossible.
[0006] The reason for this is that, although the slitting blades and perforating blades incorporated in the holders can be easily installed at any desired location on the backup roller, for example, when performing slitting or perforating, if the distance between the two is narrow, even if the holders are installed with a narrower distance, the thickness of the holders and the attachment members for the slitting blades, perforating blades, etc. get in the way, and the distance between the two is limited when adjacent circular blades are brought closer (narrowed). In other words, the lower limit of the slit width is limited by the thickness of the holders, the size of the attachment members, etc.
[0007] In view of the above problems, the present invention provides a slitting device that can perform various processes such as cutting, perforating, and creasing on any web material, can perform circular blade processing at extremely narrow intervals without being limited by the thickness of the holder or the size of the circular blade mounting member, and can attach multiple circular blades of various types to one holder, making it possible to perform multiple types of processing on a running web at any interval at once.
[0008] Another object of the present invention is to provide a method for manufacturing a bound concessionary communication article, which uses the slitting device to simultaneously and accurately perform perforation and trimming of the edge of the bound section, allowing the recipient to easily turn the pages and check the information inside. [Means for solving the problem]
[0009] In order to achieve the above object, the slitting device of the present invention processes a passing web by applying a round blade such as a slitting blade, a perforating blade or a creasing blade to the surface of a backup roller, and is characterized in that a plurality of round blades are mounted on a single shaft attached to a single holder, and a plurality of spacer adjustment spaces are installed between the plurality of round blades so that an arbitrary interval can be maintained between the plurality of round blades, and multiple types of processing can be performed simultaneously on the passing web.
[0010] In order to achieve the above object, the method for manufacturing a bookbinding type information communication body using the slitting device of the present invention includes a sheet feeding step of feeding out sheets on which unit sheets each having a plurality of leaflets connected horizontally via fold lines and information communication body paper each having unit sheets each having the same or different vertical width as the unit sheets and connected vertically, continuously printed sheets; a covering step of various film sheets to form a pseudo-adhesive film sheet on the pseudo-adhesive surface of the fed out sheet and a completely adhesive film sheet on the completely adhesive surface; and a step of cutting out one vertical margin of the sheet covered with the various film sheets and simultaneously cutting out the vertical margin on the other completely adhesive film sheet-covered side and forming a folding means inward along the cutting position. The method is characterized by comprising the steps of: a step of cutting off the vertical margins of the sheet and forming folding means using the slit device described in claim 1; a first folding step of folding the sheet after the vertical margins have been cut off and the folding means have been formed along the vertical fold line; a horizontal margin cutting step of cutting off the horizontal margins of the sheet folded in the first folding step and cutting out individual sheets for information communication devices; a second folding step of folding the individual sheets for information communication devices cut out in half along the horizontal fold line; and a bonding step of applying pressure or heat and pressure to the sheets for information communication devices folded in the second folding step to bond any opposing surfaces together in a releasable or non-releasable manner.
[0011] The slitting device of the present invention has a plurality of circular blades (slitting blades, folding or cutting perforation blades, creasing blades, etc.) attached to one shaft of one holder via thin spacers. The spacing between the circular blades is determined by the thickness of the spacers, but to widen the spacing, thicker spacer adjustment spacers can be installed or the number of spacers can be increased. To narrow the spacing, narrower spacers can be installed, and the minimum spacing can be achieved by placing the circular blades adjacent to each other without using spacers. Fine adjustment of the spacing between the circular blades can be achieved by reducing the thickness of the spacer adjustment spacers and increasing the number of spacers installed.
[0012] The pseudo-adhesive media used in information communication devices include those known in the industry as post-glue (varnish coating), pre-glue (pressure-bonded paper), and film (full-surface adhesive, sandwiched) types, but the present invention can suitably use a film-type pseudo-adhesive film sheet.Similarly, a fully adhesive film sheet can suitably be used as a fully adhesive medium.
[0013] In the method for manufacturing a bound information communication item using the slitting device of the present invention, long sheets or sheets on which information communication item paper has been printed can be suitably used. In the case of long sheets used in business form printing, etc., the aforementioned pseudo-adhesive medium can be continuously formed on the intended pseudo-adhesive surface. Furthermore, in the case of offset printing or on-demand printing, if a film-type pseudo-adhesive medium is selected, the long sheet is formed by continuously covering it with a pseudo-adhesive film sheet, and can be processed in the same manner as the long sheet. Note that pseudo-adhesive media other than the film-type can be processed in the same way as the film-type medium using an offline processing step.
[0014] In the case of long sheets of paper, the top and bottom edges of the communication paper may be printed overlapping each other without leaving any horizontal margins. Such a so-called single-cut format is also considered to be a case where the horizontal margins have been removed and is included in the scope of this invention. [Effects of the Invention]
[0015] The slitting device of the present invention can perform various processes such as cutting, perforating, and scoring on any web material, and can perform circular blade processing at extremely narrow intervals without being limited by the thickness of the holder or the size of the circular blade attachment member. In addition, since multiple circular blades of various types can be attached to one holder, multiple types of processing can be performed on a traveling web at any interval at once.
[0016] Furthermore, according to the method for manufacturing a bound information communication object of the present invention, the slitting device is used to accurately perform perforation and trimming of the edge of the bound portion simultaneously, allowing the recipient to easily turn the pages and check the information inside.

BEST MODE FOR CARRYING OUT THE INVENTION
[0018] The present invention will now be described in an easy-to-understand manner with reference to the drawings. [Slit device X] As shown in Figures 1(A) and 1(B), the slitting device X of the present invention comprises various circular blades and mounting members attached to a holder H. To explain each of these components in detail, as shown in Figure 2, a slitting blade 2a is fitted into the stepped portion of a top-shaped slitting shaft 1 inserted into the holder H, and a spacer 3 is fitted in such a way that it sandwiches the slitting blade 2a. Five spacing-adjusting spacers 4, shown dotted in the figure, are fitted into the spacer 3, and then a perforation blade 2b is fitted in from the right side. Finally, a pressure plate 5 is fixed to the slitter shaft 1 with bolts 6 to prevent the various components from coming loose. In other words, the various components mentioned above are sandwiched and fixed between the slitting shaft 1 and the pressure plate 5. These various components are then fixed to the holder H with bolts 6 by inserting the protruding portion of the slitting shaft 1 into a hole 7 in the holder H.
[0019] As shown in Fig. 1(A), the slitting device X configured as described above moves to any position on the backup roller BR by passing a holder fixing shaft (not shown) through a hole 8 provided in the holder H so that the round blades (slitting blade 2a, perforation blade 2b) come into contact with the surface of the backup roller BR. Then, the holder H is fixed so that pressure is applied to the web W by a spring or the like provided in the holder H so that the web W passing between the backup roller BR and the round blades (slitting blade 2a, perforation blade 2b) is cut and perforated.
[0020] The web W passing between the backup roller BR and the circular blade set as above is cut by the slitting blade 2a and simultaneously perforated by the perforation blade 2b. There are no restrictions on the type of circular blade that can be attached, and a slitting blade, a perforation blade (folding perforation, cut-off perforation, etc.), a crease blade, etc. can be selected according to the purpose.
[0021] Next, we will explain how to adjust the spacing between the circular blades. Figure 1(B) shows the widest spacing between the slitting blade 2a and the perforating blade 2b, with five spacing-adjusting spacers 4 placed between them. If the spacing between the slitting blade 2a and the perforating blade 2b were to be set to the narrowest, the spacing-adjusting spacers 4 could be placed on the outside of the perforating blade 2b, as shown in Figure 3(A). Furthermore, if the flange portion of the spacer 3 is omitted, the slitting blade 2a and the perforating blade 2b would be in contact with each other, minimizing the spacing between them. In this case, the overall width from the shaft 1 to the pressure plate 5 would be the same as in Figure 1(B).
[0022] The gap between the slit blade 2a and the perforation blade 2b can be adjusted according to the thickness of each gap-adjusting spacer 4. For example, in the case of Figure 3(B), three gap-adjusting spacers are interposed between the slit blade 2a and the perforation blade 2b compared to Figure 3(A), and the width is increased by the thickness of these spacers. Even in this case, there is no difference in the overall width from the shaft 1 to the pressure plate 5.
[0023] [Book-bound Information Communication Unit J] A description will now be given of a bound information communication object J manufactured using the slitting device X. The bound information communication object J shown in Fig. 4(A) is made up of, from top to bottom, the fourth leaf piece 14, the fifth leaf piece 15, the sixth leaf piece 16, the third leaf piece 13, the second leaf piece 12, and the first leaf piece 11, which are folded and stacked in an accordion-like manner along fold lines 17 and 18, as shown in Fig. 4(B). The opposing surfaces of the leaves are stacked so that they can be peeled apart by the interposition of a pseudo-adhesive film sheet G, but one end between the sixth leaf piece 16 and the third leaf piece 13 is completely and non-peelably bonded to each other by a complete adhesive film sheet K.
[0024] The aforementioned bookbound information communication device J can be peeled apart between the opposing surfaces of the pseudo-adhesive film sheets. When the recipient peels and unfolds it, it unfolds in a bound state with the ends of the sixth leaf piece 16 and the third leaf piece 13 adhered by the fully adhesive film sheet K, as shown in Figures 5(A) and (B). The recipient can then view the various information displayed inside through the transparent or semi-transparent pseudo-adhesive film sheet G.
[0025] [Manufacturing method of bound information communication body J] Next, a method for manufacturing the bookbinding type information communication product J using the slitting device X will be described. 6 shows a sheet S for producing a bound information communication medium J of the present invention. This sheet S is a single sheet with information communication medium paper P printed in the center, surrounded by a horizontal margin Y1 and a vertical margin Y2.
[0026] The information communication paper P printed on the sheet S is made up of unit sheets each consisting of a first leaf piece 11, a second leaf piece 12, and a third leaf piece 13 connected laterally via vertical fold lines 17 and 18, and unit sheets each consisting of a fourth leaf piece 14, a fifth leaf piece 15, and a sixth leaf piece 16 connected laterally via the vertical fold lines 17 and 18, and the unit sheets are arranged so that the first leaf piece 11 and the fourth leaf piece 14, the second leaf piece 12 and the fifth leaf piece 15, and the third leaf piece 13 and the sixth leaf piece 16 face each other via a horizontal fold line 19. Note that planned cutting lines 20 for final cutting are shown at the top and bottom along the horizontal fold line 19, but this indication is not necessarily required.
[0027] Then, when the sheets S having the above-described configuration are fed one by one sequentially to the conveying route (sheet feeding process), pseudo-adhesive film sheets G and fully adhesive film sheets K are continuously fed from, for example, rolls on the front and back surfaces of the sheets, and are covered as shown in Figures 7(A) and 7(B) (film sheet covering process). Note that in Figure 7, the state in which one sheet S is covered with various film sheets is shown by dots, but during production, the preceding and succeeding sheets S are transported closely on the same route and are continuously covered with the various film sheets, so the sheet S is connected by the various film sheets and is in the form of a long sheet.
[0028] The sheet S, which has now been made into a long length, is then cut off at its vertical margins Y1, Y1 shown in Figures 7(A) and (B) by a slitting device.The vertical margin Y1, which is covered by the fully adhesive film sheet K on the right side shown in Figure 7(A), is cut off by the slitting device X of the present invention, so that at the same time as the vertical margin Y1 on the right side is cut off by the slitting blade 2a, a folding perforation 21 is provided in the gap between the pseudo-adhesive film sheet G and the fully adhesive film sheet K by the perforation blade 2b (process of cutting off the vertical margin and forming the folding means).
[0029] As shown in Figures 8(A) and (B), the sheet is folded continuously along vertical fold lines 17 and 18 (perforations or creases may be formed) so that the front and back surfaces of each leaf face each other, creating a Z-shaped cross section (first folding process), and then the horizontal margins are cut off using a guillotine-type cutting machine or the like (horizontal margin cutting process), thereby cutting out individual pieces of information and communication paper P (with a Z-shaped cross section).
[0030] Next, the sheet is folded in half along the horizontal fold line 19 shown in Fig. 8(A) so that the third leaf piece 13 and the sixth leaf piece 16 face each other, as shown in Fig. 9(A) and (B) (second folding process). At this time, the edge formed by the horizontal fold line 19 is in a sealed state as shown in Fig. 9(B), so it needs to be cut open along the planned cutting line 20 (finishing cutting process). The cutting process is performed either before or after the bonding process of the sheet for information communication devices, which will be described later.
[0031] In the bonding process of the sheet P for information communication devices, for example, the sheet is heated by passing it between multiple heater panels and then bonded with a pressure roller installed at the outlet, or the sheet is passed through a heat roll and simultaneously heated and pressurized to bond it, or depending on the properties of the pseudo-adhesive film sheet G or the fully adhesive film sheet K, the sheet is bonded so that it can be peeled or not by applying pressure (bonding process of the sheet for information communication devices). As mentioned above, the finishing cutting step may be performed at any location upstream or downstream of the main bonding step.
[0032] Although the bookbound information communication device J is manufactured through these various processes, the manufacturing process is not necessarily limited to the above-mentioned flow of work steps. In both the case of single sheets and continuous sheets, each process can be carried out separately. For example, a single sheet or continuous sheet can be covered with various film sheets and then cut into individual sheets for information communication devices (cutting process), which can then be folded into their final form (folding process) and glued (gluing process). In this case, the finishing cutting process can be performed either before or after the gluing process, which is the same as the manufacturing process described above. [Explanation of symbols]
