Fig.1 (a) is a perspective view of the label roll 20, FIG.1 (b) is the bb sectional view taken on the line of Fig.1 (a). A label roll 20 is obtained by winding a continuous label body 10 in which a label piece 2 composed of a label base material 3 and an adhesive layer 4 is temporarily attached to a long release mount 5 at a predetermined interval around a cylindrical core 11. It is. The surface of the label piece 2 is an image display area that can be printed by a label printer (not shown).

    In the peeling mount 5 of the label roll 20, a cut 30 penetrating the peeling mount 5 is formed. The shape of the cut 30 is substantially U-shaped, and a line segment 31 (hereinafter referred to as a fold line 31) connecting both ends thereof is substantially parallel to the conveyance direction of the adhesive paper. A region defined by the folding line 31 (indicated by phantom lines) and the cut 30 is a punched portion 32 that exposes the pressure-sensitive adhesive layer 4 by turning over the peeling mount 5 triggered by the cut 30.

    Next, a method for manufacturing the label roll 20 shown in FIG. 1 will be described with reference to FIG. The figure is a schematic side view of the label processing machine 40.

    The label processing machine 40 includes a feeding process 51, a first front surface printing process 52, a second front surface printing process 53, a back surface printing process 54, a cutting process 55, a die cutting process 56, a scrap winding process 57, A winding process 58 is included.

    In the feeding step 51, the label base material 3, the adhesive layer 4 and the release mount 5 are laminated in this order and wound in a roll shape, and the adhesive paper 1 is mounted on the supply shaft 60 in a rotatable state. The adhesive paper 1 is fed out as the shaft 60 rotates. The fed adhesive paper 1 is guided by the guide roller 61 and proceeds in the order of the first front surface printing step 52, the second front surface printing step 53, and the back surface printing step 54.

    The first surface printing step 52 includes a printing unit 64 mainly composed of a plate cylinder 63 and an impression cylinder 62, and a UV lamp 65 provided downstream thereof. The pressure-sensitive adhesive paper 1 is conveyed by narrowing the pressure-sensitive adhesive paper 1 between the plate cylinder 63 and the impression cylinder 62, and supplying a UV curable ink to the plate cylinder 63 so that desired characters are provided on the label base 3 side of the pressure-sensitive adhesive paper 1. And print symbols. The ink printed on the adhesive paper 1 is cured by irradiating ultraviolet rays from the UV lamp 65.

    Similar to the first surface printing step 52, the second surface printing step 53 includes a printing unit 66 mainly including a plate cylinder 67, an impression cylinder 68, and the like, and a UV lamp 69 provided downstream thereof. The pressure-sensitive adhesive paper 1 is transported with the plate cylinder 67 and the pressure drum 68 being narrowly pressed and supplied with UV curable ink to the plate cylinder 67 to provide desired characters on the label base 3 side of the pressure-sensitive adhesive paper 1. And print symbols. Then, the ink printed on the adhesive paper 1 is cured by irradiating ultraviolet rays from the UV lamp 69, guided by the plurality of guide rollers 70 and 71, and proceeds to the back side printing step 54 of the next step.

    Similar to the first front surface printing step 52 or the second front surface printing step 53, the back surface printing step 54 includes a printing unit 74 mainly composed of a plate cylinder 73 and an impression cylinder 72, and a UV lamp provided downstream thereof. 75. Further, the back surface printing step 54 can print a desired character or design on the side of the release mount 5 of the adhesive paper 1 and can also print a timing mark (not shown) necessary for printing with a label printer. The printed adhesive paper 1 is then guided to the guide roller 76 and proceeds to the mount cutting process 55.

    The board cutting process 55 is a process of cutting the release board 5 of the adhesive paper 1 to form the curled portion 32. For example, the adhesive paper 1 is sandwiched between a roll with a blade called a die roll 78 and an anvil roll 77, and the die roll 78 is pressed against the release mount 5 and rotated to rotate the cut 30 that penetrates only the release mount 5 into the release mount 5. Form.

    The die cutting process 56 is a process of performing a half cut from the label base material 3 side of the adhesive paper 1 to the adhesive layer 4. The half-cut line forms the contour of the desired label piece 2 by sandwiching the adhesive paper 1 between a roll with a blade called a die roll 79 and an anvil roll 80 and pressing the die roll 79 against the label substrate 3 and rotating it. To do. A pair of waste removal rollers 81 and 82 that are provided downstream of the die roll 79 and separate the label residue 6 from the adhesive paper 1 are disposed.

    The winding process 58 is provided with a winding shaft 85 for winding the label continuum 10, and the scrap winding process 57 includes a scraping roller so as to remove unnecessary scraps other than the label pieces 2 in the die cutting process 56. 81 and 82 are provided.

    The label roll 20 is processed as follows. As shown in FIG. 2, the adhesive paper 1 wound in a roll shape on the supply shaft 60 in the feeding process 51 passes through the guide roller 61 to the first surface printing process 52 and the second surface printing process 53. The characters are transferred to the label base 3 and printed with ultraviolet curable ink on the label base 3 side. The printed ink is instantly cured by the UV lamps 65 and 69. Subsequently, the adhesive paper 1 is sent to the back surface printing step 54, and a timing mark is printed on the back surface of the release mount 5 with ultraviolet curable ink in addition to characters and designs. The printed ink is instantly cured by the UV lamp 75.

    After the printing, the adhesive paper 1 reaches the board cutting process 55, and the blade of the die roll 78 is pressed against the peeling board 5 to form the cut 30. The depth of cutting is such that it penetrates through the release mount 5 and slightly bites into the adhesive layer 4. The notch 30 is a substantially U-shaped notch 30, and a portion defined by a fold line 31 and the notch 30 that connect both ends of the notch 30 is a turning part 32. The turning part 32 is an area defined by the folding line 31 and the cut 30.

    The folding line 31 that divides a part of the curled portion 32 is provided substantially parallel to the longitudinal direction of the adhesive paper 1. This is for avoiding troubles such as the curled portion 32 being curled, the adhesive layer 4 sticking to the guide roller 84, or the adhesive paper 1 being cut during labeling or when printing with a label printer.

    The adhesive paper 1 that has passed through the mount cutting process 55 reaches the die cutting process 56, and the die roll 79 performs a half cut of a predetermined shape from the label base material 3 side to the adhesive layer 4 to form the outline of the label piece 2. The adhesive paper 1 in which the label pieces 2 are partitioned is peeled off the label residue 6 by the residue removing rollers 81 and 82, and the continuous label body 10 appears. The label continuum 10 is wound around the winding shaft 85 with the release mount 5 facing inward.

Next, the winding operation of the label continuous body 10 in the winding process 58 will be described in detail with reference to FIGS. 3 and 4.
FIGS. 3A to 3C are diagrams for sequentially explaining the operation of fixing the end of the label continuous body 10 to the core 11. FIG. 4 is a cross-sectional view of the label continuum 10 shown in FIG. The line cc is along the center of the width of the label continuum 10.
In Fig.3 (a), the label piece 2 which is the edge part of the label continuous body 10 is pressed and distorted with a fingertip from the label surface side. Then, a part of the turn part 32 located on the back side is peeled off and becomes a floating state. When the lifted turn 32 is picked up with a fingertip, the adhesive layer 4 under the turn 32 is exposed. Further, the turning portion 32 is picked and the folding line 31 is folded back 180 degrees to the base line.
Subsequently, the pressure-sensitive adhesive layer 4 exposed as shown in FIGS. 3 (b) and 4 is pressure-bonded to the outer periphery of the core 11. The end of the label continuous body 10 is fixed to the core 11 as shown in FIG. By rotating the winding shaft 85 on which the winding core 11 is set in this state, the label continuous body 10 fixed to the winding core 11 is wound into a roll shape, and the label roll 20 is manufactured.

    According to the manufacturing method of the label roll 20 of the present invention, the core 11 and the label continuous body 10 can be easily fixed by forming the cut 30 in the peeling mount 5. Further, it is not necessary to use an adhesive tape 95 or the like other than the label roll 20, and the working efficiency is increased.

    As shown in FIG. 5, the method for manufacturing the label roll 20 of the present invention can also be applied to an operation for dividing a large roll of label rolls 21 (hereinafter referred to as a small roll operation). The small roll operation is to produce a large roll of label roll 21 by winding the continuous label body 10 that is the basis of the label roll 20 around a length of several hundred to several thousand meters on a single core. Thereafter, this large roll of label rolls 21 is divided into a predetermined number of sheets or rolls having a predetermined winding diameter to obtain a plurality of label rolls 20.

    Similarly to the winding process 58 of the label processing machine 40, the small winding operation is also turned 180 degrees by turning over the curled portion 32 of the large-sized label roll 21 in which the curled portion 32 is previously formed by the label processing machine 40 or the like. The label roll 20 can be produced by fixing the wound pressure-sensitive adhesive layer 4 to the winding core 11 fitted to the winding shaft 89 and winding it.

    Moreover, when fixing the outer periphery of the label roll 20 produced by the small winding operation, the end of the roll is fixed by affixing the exposed adhesive layer 4 to the inner surface of the label, and the roll of the label roll 20 is not collapsed. It can also be prevented. When used for fixing the outer periphery of the label roll 20, it is desirable that the adhesive strength of the pressure-sensitive adhesive layer 4 be 50 to 500 gf / 25 mm (JIS Z 0237) re-peeling adhesive or weak adhesive. When the adhesive strength is less than 50 gf / 25 mm, the sticking is weak and is not suitable. When the adhesive strength exceeds 500 gf / 25 mm, the outer periphery of the label roll 20 can be firmly fixed, but the sticking is too strong, and there is a risk of damaging the surface of the label substrate 3 on the inner side when peeling off.

    In addition, the cut 30 is provided as a trigger for turning the turning portion 32 and may be formed within the range of each label piece 2 of the label continuous body 10. The cut 30 may be formed on the leading side or the trailing side of the label piece, and the position is not particularly limited.

    The shape of the cut 30 may be a combination of straight lines such as a V shape, a combination of straight lines and curves such as a U shape, or a curve such as an S shape. In addition, a shape such as H, J, L, M, N, T, X, Y, Z may be used.

    Furthermore, in order to prevent troubles such as the turning portion 32 of the peeling mount 5 being rolled during the conveyance and printing of a label printer or the like, the cut 30 may be provided with a so-called spotted connection. This cut 30 is preferably in the shape of a one-dot chain line.

    In the processing method described above, the die rolls 78 and 79 and the anvil rolls 77 and 80 are used for the mount cutting process 55 and the die cutting process 56, but a flat die may be used. A flexible die may be used as the die rolls 78 and 79.

    Further, in the mount cutting process, the curled portion 32 is provided in each label piece 2, but may be provided every plural sheets. By forming intermittently, wear of the blade of a die roll, a flat die, or a flexible die can be reduced.

    The type and material of the label base 3 constituting the label piece 2 are not particularly limited, such as paper or a synthetic resin film, and are generally used as the adhesive paper 1. For example, a paper substrate such as fine paper, coated paper, art paper, synthetic resin film made of PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), PS (polystyrene), or the above synthetic resin A composite sheet obtained by combining a plurality of types and a synthetic resin film and paper can be used. Thermal paper may be used.

    The pressure-sensitive adhesive of the pressure-sensitive adhesive layer 4 constituting the label piece 2 may be, for example, an emulsion system (a pressure-sensitive adhesive dispersed in water), a solvent system (a pressure-sensitive adhesive dissolved in a solvent), a hot melt system (thermoplastic Used). Examples of the material include adhesives such as synthetic rubber type, natural rubber type, acrylic resin type, polyvinyl ether resin type, urethane resin type, and silicone resin type. In addition, the adhesive force of an adhesive can be set according to a use.

    The peeling mount 5 is a general purpose one. For example, there may be mentioned paper or film coated with a fluorine-based release agent in addition to ultraviolet curable silicone, thermosetting silicone, solvent silicone, alkyl pendant polymer. As the peeling ability of the peeling mount 5, a lightly peeled or heavyly peeled one is appropriately selected according to the adhesive strength of the pressure sensitive adhesive.

    It should be noted that the present invention is not limited to the above-described embodiment, and it is obvious that each embodiment can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, arrangement, and the like of the above-described constituent members are not limited to the above-described embodiment, and can be set to a suitable number, position, shape, and the like for carrying out the present invention.
