Description

  In the present invention, a laminator that heats and pressurizes the surface of a printed material such as a poster or a pamphlet to cover a film sheet, or an integrated treatment by a similar process, a plurality of leaf pieces are folded or stacked in a peelable manner. The present invention relates to a method for manufacturing an information communication body.

For posters and pamphlets, in order to improve aesthetics and add durability, conventionally, a laminate process is performed in which the surface of a printed material is covered with a transparent or translucent film sheet. In the lamination process, without the use of solvent, aligned beforehand sensitive adhesive is formed film sheet to the target surface of the printed matter by performing heating and pressing treatment by Hitoro La, etc., and the film sheet In recent years, a thermal laminating method for firmly bonding the target surface of a printed material has been widely employed. Recently, although an appearance is a single postcard or a sealed letter, an information communication body in which a plurality of pieces of paper are detachably stacked has been seen. In such a method of manufacturing an information communication body, Also, the integration process by the thermal laminating method is adopted.

  By the way, the printed matter subjected to the heating / pressurizing treatment tends to warp particularly to the surface side coated with the film sheet. This is a result of bonding paper and film sheets of different materials by heating or pressure treatment, but the same treatment is performed by interposing a pseudo adhesive medium such as a pseudo adhesive film sheet between the opposing surfaces. The same tendency is seen also in the manufacturing method of the information communication body integrated so that peeling is possible.

  As a method of dealing with the curl, in a general laminate, a means for removing curl generated in a printed matter after coating is provided by providing a curl correcting portion as disclosed in, for example, Japanese Patent Laid-Open No. 10-315424. However, in the manufacturing method of the information communication body, no concrete means for coping with curl is currently considered, and as it is seen in Japanese Patent Application Laid-Open No. 2007-144971, it is discharged in a curled state from the integration process. By cooling air to the information communication body, the rough heat is removed and the recovery time from the curled state is shortened.

Japanese Patent Laid-Open No. 10-315424 JP 2007-144971 A

  In the laminator of Patent Document 1, a curl correcting unit 40 including a curl correcting member 41, an angle adjusting roller 42, and an idle roller 43 is installed as means for removing curl generated in the printed matter after coating. However, a space for adding such a process is required, and naturally the system must be expanded. In particular, the angle adjusting roller 42 needs to be moved largely in the vertical direction depending on the condition of the paper, so that it is necessary to secure not only the front and rear but also the vertical space. In addition, various components are newly required, and thus the price of the system itself is rebounded.

In view of the above problems, the present invention provides a curl removal mechanism that can be applied to a method of manufacturing an information communication body while removing curl generated during lamination with a simple structure that does not take up space.

In order to achieve the above object, the decurling mechanism of the laminate according to the present invention includes one or a pair of discharge rollers for discharging the laminate subjected to the heat and pressure treatment, and a downstream side of the discharge roller. In addition, at least a pair of nip rollers are provided so that the laminate is discharged at an angle downward with respect to the laminate conveyance line upstream of the discharge roller.

In order to achieve the above object, the method of manufacturing an information communication body using the decurling mechanism of the laminate of the present invention heats and heats the information communication body paper in which a pseudo adhesive film sheet is interposed between the opposing surfaces. In the manufacturing method of an information communication body that is integrated so as to be peelable as a whole by performing pressure treatment, information communication on the upstream side of the discharge roller is provided downstream of the discharge roller that is heated and pressurized on the information communication body and discharged. It is characterized in that at least a pair of nip rollers are provided so that the information communication body is discharged at an angle downward with respect to the body conveyance line.

  As a specific means for the heating / pressurizing process, for example, a pair of heat rollers or a combination of a heat roller and a rubber-lined backup roller may be used, or the heating process may be performed by a heater panel or the like. You may make it implement by a pair of pressure roller after giving. A heat roller that can be heated / pressurized for discharging, a normal nip roller, or the like is disposed as the discharging roller.

Wherein when placed in a pair of nip rollers have the same height as the passage line of the laminate material, when the lamination product through is discharged from the pair of nip rollers, the I Cormorant the rollers and is discharged at an angle downwardly Set the position of the contact point with an inclination. As the angle is greatly inclined from the horizontal, the degree of correction to curl increases. Therefore, the degree of freedom is adjusted so that the angle can be adjusted depending on the type of laminate (quality of paper, type of mat, coat, etc.) and thickness (heavy weight of paper), and even the same type depending on the brand. It is preferable to have it.

Further by arranging below the pass line of the laminate material to the discharge roller pair of Nippuro La, but the laminate was to be discharged with an angle induced downwardly with respect to the passing line, the The degree of correction to curl increases as it is guided significantly downward from the passing line. Therefore, the degree of freedom is adjusted so that the angle can be adjusted depending on the type of laminate (quality of paper, type of mat, coat, etc.) and thickness (heavy weight of paper), and even the same type depending on the brand. It is preferable to have it.

Also, the pair of nip rollers without regard be pairs arranged, it may be arranged so as to stepwise curl is forced.

Embodiments of the present invention will be specifically described below with reference to the drawings.
[Example 1: Curling mechanism of laminate]
As shown in FIG. 1, the laminator provided with the laminate curl removing mechanism of the present invention has, for example, the uppermost printed product S of a plurality of stacked sheet-like printed products S, by a paper feeding mechanism such as a suction pad P, It is sequentially fed out to the right transport table with equal intervals or end-to-end but overlapping ends. The fed-out printed matter S is held at the front end by nip rollers 1a and 1b arranged on the right side, and is further fed to a laminating apparatus comprising a pair of heat rollers 2a and 2b on the right side.

  In the laminating apparatus, the planned coating surface of the printed material to be passed and the film sheet F fed from the roll waiting on the upper side are aligned, and a heat roller is passed through a heat-sensitive adhesive layer formed in advance on the film sheet F. Both are firmly bonded by being heated and pressurized by a laminating apparatus such as 2a or 2b.

Thereafter, between the discharge rollers 4a and 4b disposed on the right side, for example, the printed sheet S conveyed continuously while overlapping the front and rear end portions is covered with the film sheet F. And in the film sheet overlapping ends of the printed material S of the continuous state by F, by separating by known cutting means film sheets F which are covered by the cutter 3 and the like, that are finished initial each individual printed matter S .

  As shown in FIG. 2, the separated printed matter S is guided to the nip rollers 6a and 6b arranged at a lower position on the right side by the guide plate 5, and is then sent out along a path line that goes obliquely downward.

  Usually, the printed matter S coated with the film sheet F is curled to the side on which the film sheet F is coated. That is, in this embodiment, it curls upward. However, the printed matter S that has been discharged downward from the nip rollers 4a and 4b and then proceeds downward is handled by the nip rollers 4a and 4b, and the tendency to curl upward is canceled by the above-described processing, and is corrected to a substantially flat surface. It is.

  Thus, the printed matter S with the curl corrected as described above is stacked on a paper stacking table (not shown) arranged on the right side of the nip rollers 6a and 6b, or sent to the next process arranged downstream. .

[Example 2: Manufacturing method of information communication body using decurling mechanism of laminate ]
The laminate using the curl removing mechanism described above is in a form in which the film sheet F is coated on a surface to be coated such as a printed material. In addition to such a form, the same curl occurs in the manufacture of an information communication body in which a plurality of pieces of paper are laminated in a peelable manner. The information communication body integrates opposing pseudo adhesion planned surfaces so as to be peeled off via a pseudo adhesive film sheet. When the recipient opens, the information communication body is peeled off from the pseudo adhesive portion of the pseudo adhesive film sheet and developed after peeling. Both pseudo-adhesive surfaces are covered with the separated pseudo-adhesive film sheet.

An embodiment of a method for manufacturing an information communication body using the laminate curl removing mechanism of the present invention will be specifically described below based on a basic two-fold postcard.
(1: A method of finishing a folded postcard paper t1 from a long sheet S1)
FIG. 3 shows a two-fold postcard paper t1 printed on a long sheet S1 used for rotary printing or business form printing. For example, as shown in FIG. 2A, a two-fold postcard paper t1 in which a first paper piece 11 and a second paper piece 12 are connected in a lateral direction via a fold line 13 is passed through a cut-out line 14 in the vertical direction. Are connected in the vertical direction. A marginal portion 17 provided with a marginal hole 16 is connected to the outside of the first paper piece 11 and the second paper piece 12 via a tear line 15.

  On the surface of the first paper piece 11, for example, a postage stamp field, a postal code field, a recipient's address name and the like are described. Further, general information 18 such as advertisements is described on the surface of the second paper piece 12.

  Similarly, as shown in FIG. 3B, the personal information 19 of the recipient (general information or the like) may be written on the backs of the first paper piece 11 and the second paper piece 12. And each said back surface side becomes a pseudo-adhesion scheduled surface, is finally folded from the fold line 13, and is integrated so that peeling is possible via the pseudo-adhesive film sheet G1.

The elongated sheet S1 is first paper 11 and the second paper 12 from in fold line 13 is folded sequentially to face. At the same time, for example, a pseudo-adhesive film sheet having a four-layer structure in which a known heat-sensitive adhesive layer is formed on both outer sides of a thermoplastic resin releasably laminated on one surface of a base material such as polyethylene terephthalate or biaxially stretched polypropylene. G1 is inserted a (in which represents a double layer in the drawing) between the opposing surfaces, separate clamshell postcard for paper as shown in FIG. 4 and cutting in the vertical direction of the tear line 14 along with subsequently ablating both marginal portions Finished at t1.

The individually finished bi-fold postcard paper t1 (with the pseudo-adhesive film sheet G1 sandwiched between the opposing paper pieces) is integrated in a releasable manner as a whole in a subsequent integration process. Before the explanation, different modes for finishing individual unit sheets are described below.

(2: A method of finishing the folded-fold postcard paper t2 from the sheet-like sheet S2)
FIG. 5 shows a sheet-like sheet S2 used for offset printing or the like, in which two folded postcard sheets t2 are printed on one sheet. For example, as shown in FIG. 2A, two folded postcard sheets t2 in which a first paper piece 21 and a second paper piece 22 are connected in a horizontal direction via a fold line 23 are arranged in two vertical directions. It is printed.

  On the surface of the first paper piece 21, for example, a postage stamp field, a postal code field, and the address name of the recipient are described. Further, general information 18 such as advertisements is described on the surface of the second paper piece 22.

  Similarly, as shown in FIG. 5B, the personal information 19 of the recipient (general information or the like) may be written on the backs of the first paper piece 21 and the second paper piece 22. And each said back surface side becomes a pseudo-adhesion scheduled surface, is finally folded from the fold line 23, and is integrated so that peeling is possible via the pseudo-adhesive film sheet G2.

  The sheet-like sheet S2 has a well-known heat-sensitive adhesion to one side of a base material made of, for example, polyethylene terephthalate or biaxially oriented polypropylene, on the back side of the pseudo-adhesion planned surface (the back side of the first paper piece 21 and the second paper piece 22). A pseudo-adhesive film sheet G2 for a print laminate having a pseudo-adhesive layer formed on the other side of the remaining adhesive layer is coated via the heat-sensitive adhesive layer, and then cut and folded through a pseudo process. The sheets are folded so that the surfaces to be bonded face each other, and finished into individual two-fold postcard paper t2 as shown in FIG.

(3: Integration process of two-fold postcard papers t1 and t2)
The two-fold postcard sheets t1 and t2 finished individually as described above are sent to the integration step shown in FIG. In the integration step, a pair of conveying rollers 31a and 31b and a pair of heater panels 32a and 32b are alternately arranged, and heat treatment is performed on the two-folded postcard papers t1 and t2 that are passed through, and are arranged at the discharge port. Pressure is applied by the discharge rollers 33a and 33b.

  When the heating / pressurizing process is performed, the heat-sensitive adhesive layer of the pseudo-adhesive film sheet G1 exerts adhesiveness on the two-folded postcard paper t1, and the opposing pieces of paper and the pseudo-adhesive film sheet G1 adhere to each other. Integrated. Further, in the two-fold postcard paper t2, the pseudo adhesive layers of the opposing pseudo adhesive film sheet G2 are pseudo-bonded so as to be peeled, and are integrated so as to be peelable as a whole.

  Note that the two folded postcard sheets t1 and t2 discharged from the discharge rollers 33a and 33b tend to curl upward. This is presumably because when the heating is performed by the pair of heater panels 32a and 32b, the hot air from both heater panels is transmitted upward and stays, so that the upper side of the two-folded postcard paper passing through is heated more.

  However, in the present invention, as shown in FIG. 7, the nip rollers 35a and 35b arranged on the right side of the discharge rollers 33a and 33b are used to follow the conveyance path through which the folded paper t1 and t2 are drawn out while being handled downward. The tendency to curl upward is offset.

The present invention is not limited to the above embodiment.
For example, as described above, regarding the arrangement of the discharge roller and the pair of nip rollers for handling the information communication body and canceling the curl with respect to the transport path of the printed matter that is subjected to the heating / pressurizing process and tends to curl upward As shown in FIG. 8A, each roller may be arranged on the same transport line. In that case, the arrangement of the pair of nip rollers 42a and 42b needs to be inclined so as to discharge downward with respect to the conveying line from the discharge rollers 41a and 41b so that the printed matter and the information communication body passing therethrough are handled downward. is there.
Further, as shown in FIG. 5B, a pair of nip rollers 42a and 42b may be disposed below the conveyance line and handled downward by the discharge rollers 41a and 41b.
Further, as shown in FIG. 5C, the nip rollers 42a and 42b are arranged below the transport line and are inclined so that they can be handled by both the discharge rollers 41a and 41b and the nip rollers 42a and 42b. I do not care.
Further, as shown in FIG. 4D, a plurality of pairs of nip rollers 42a, 42b and 43a, 43b may be arranged to give an inclination stepwise .

As for the discharge rollers, although in the embodiment uses a pair of Nippuro la, may be used alone as a support roller 41b only lower roller, as shown in FIG.
