DETAILED DESCRIPTION OF THE INVENTION
  A method for producing a label according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing the configuration of a label sheet 2 used in the method for manufacturing a label superimposed body according to the present invention. The label sheet 2 is an intermediate process product processed in an intermediate process for manufacturing an adhesive label. The label sheet 2 has a multilayer structure, and printing paper 4 is arranged on the back surface, that is, the lowest layer in the drawing. The surface of the printing paper 4, that is, the upper surface in the drawing, is a sealant layer 6 provided as necessary, and an ink layer 8 for recording information is printed and adhered thereon. Further, a release layer 10 made of silicone or the like having a release function is provided on the ink layer 8, and the uppermost layer, that is, the surface of the label sheet 2 is an adhesive layer 12 to which an adhesive is applied. It is.
[0011]
  The label sheet 2 having such a configuration is obtained by printing predetermined information on a printing paper to obtain a printing paper having a surface as a printing surface, and applying a release agent such as silicone to the printing surface of the printing paper. Furthermore, it can be made by coating the pressure-sensitive adhesive after applying the release agent.
[0012]
  First, the label sheet 2 is wound using means for winding a sheet-like material so as to form a wound body 20 as shown in FIG. This winding is preferably performed by winding the label sheet 2 continuously following the above-described step of applying the pressure-sensitive adhesive.
[0013]
  As is obvious from the winding structure of the wound body 20, an arbitrary portion of the surface of the label sheet 2 is adjacent to and in contact with the back surface of the portion of the label sheet 2 wound from the portion by one turn.
[0014]
  The wound body 20 is preferably left for several days after being wound up. By this aging, the pressure-sensitive adhesive layer 12 on the surface of the label sheet 2 is formed on the back surface of the printing paper 4 on the back surface of the label sheet 2 adjacent to the pressure-sensitive adhesive layer 12 in the roll 20. It was found to migrate.
[0015]
  By this transition, the structure of the label sheet 2 as viewed from the cross section is changed to an aged sheet 2m shown in FIG. The adhesive layer 12 is aged to form an adhesive layer 13 on the back surface of the aging sheet 2m in FIG. The upper surface of the pressure-sensitive adhesive layer 12 is a printing paper 4, and a sealing agent layer 6 is provided on the printing paper 4 as necessary, and an ink layer 8 for recording information is attached thereon. . Furthermore, a release layer 10 such as silicone having a release function is present on the ink layer 8 as the uppermost layer. That is, the surface of the aging sheet 2 m is the release layer 10.
[0016]
  The mature sheet 2m is perforated in the shape of the label 50. This perforation is given to the label sheet 2 before aging.
[0017]
  The aged sheet 2m having such an adhesive layer on the back surface becomes the label carrying sheet 3m. Further, the wound body 20 is a label wound body 20r made of the label carrying sheet 3m.
[0018]
  In the description of the present specification, a label carrying sheet is a sheet in which a label is carried through a seam such as a perforation. Further, in the description of the present specification, a perforation is an intermittent cut given to a processed sheet such as printing paper, and printing paper or the like by a die cutting machine using an intermittent linear blade or the like. It is given to the processed sheet.
[0019]
  FIG. 4 shows a label sheet 2 s provided with perforations 30. The same applies to the perforation shape attached to the corresponding aging sheet. The perforation 30 has an uncut seam 32, and the other part is a cut 33. Moreover, it has the structure that the adhesive agent does not exist in both edge portions 34 along the longitudinal direction of the sheet 2s for labels.
[0020]
  By removing the label 50 from the label-carrying sheet and sequentially stacking it in layers, an adhesive label superposed body can be obtained.
  Conventionally, in order to obtain a superposition of adhesive labels, first a label carrying sheet with release paper is made, then the release paper is peeled off from the label carrying sheet with release paper, then the labels are removed according to the cuts, and sequentially layered. By superimposing, a superposed body of adhesive labels was obtained. On the other hand, in the present invention, an adhesive label superimposed body can be obtained without using release paper as described above.
[0021]
  The process of removing the labels from the label carrying sheet 3m and sequentially stacking them in layers can be performed by the method shown in FIG. In the schematic side view of FIG. 5A, the label winding body 20 r made of the label carrying sheet 3 m is intermittently pulled out by the pulling roll 92 and supplied to the label superimposed body manufacturing apparatus 90.

Pressed on top of. The vertical movement of the punch member 97 and the central push plate 112 is performed in the order of FIGS. 5 (a), 5 (b), and 5 (c). That is, the punching member 97 and the central push plate 112 descend from the fixed position before punching in FIG. 5A to push the label carrying sheet 3m to the position shown in FIG. 5B. Thereafter, the central push plate 112 further descends to the position shown in FIG. 5 (c), and the central portion of the label separated by the action of FIG. 5 (b) is placed on the label 100f already separated in the previous cycle. Press to ensure adhesion. Thereafter, the punching member 97 and the central pressing plate 112 are returned to the position shown in FIG. 5A, the label carrying sheet 3m travels a predetermined length, and the label to be punched comes directly under the punching means 94.
[0025]
  The mounting table 106 is provided directly below the label superimposed body 102 that is formed by sequentially placing the punched labels on the labels that have been punched in the immediately preceding cycle, and places the label superimposed body 102 thereon. . The mounting table 106 is lowered by a predetermined length by a lowering means (not shown) every time a new label is pushed out and placed on the label pushed out in the immediately preceding cycle. As a result, the uppermost label surface of the label superimposing body 102 is always kept at a substantially equal distance with respect to the position of the lower end portion at the lowest point of the punching member 97 or the central push plate 112. The label superimposed body 102 on which a predetermined number of labels are superimposed is collected from the mounting table 106.

In FIG. 10, reference numeral 72 is a perforation for separating the ear 68 from the label, and reference numeral 74 is a perforation at the boundary between the labels.
[0036]
  FIG. 11 is a schematic diagram showing an aspect of a manufacturing process for manufacturing the label sheet 2. First, a coater 82 is used to print and apply a sealing agent on the surface 81 on the printing paper 80 that runs in the direction of the arrow, and then predetermined information is printed on the printed surface by the printing means 84. A silicone treatment agent is applied and wound up as a wound body 88 by a winding means 86.
[0037]
  Next, the printing paper 80 wound as the winding body 88 and printed and coated with a silicone treatment agent is supplied to a die-cutting machine to give predetermined perforations as shown in FIGS. And it winds up again as a winding body.

An adhesive is applied and then dried through a dryer 93 to obtain the label sheet 2. The label sheet 2 is then wound up by the winding means 96 as a wound body 20 made of the label sheet 2. Next, the wound body 20 made of the label sheet 2 is left for a predetermined time to become a wound body made of the label carrying sheet.
[0039]
  In the step of applying the pressure sensitive adhesive as shown in FIG. 12, the pressure sensitive adhesive can be easily and uniformly applied to the surface subjected to the silicone treatment. For the purpose of directly obtaining the label sheet having the structure shown in FIG. 3, even if the adhesive is to be applied directly to the back surface of the printing paper printed on the front surface, the adhesive coating liquid soaks into the back surface of the printing paper during application. It is difficult to perform a predetermined uniform application.
[0040]
  The perforation by the die-cutting machine may be performed before the silicone treatment agent is applied to the printed printing paper. In this case, the printing process and the process of applying the silicone treatment agent are performed separately rather than as a continuous process as shown in FIG.
[0041]
  Using the label superimposed body manufacturing apparatus 90, a label superimposed body can be manufactured from a normal label carrying sheet with release paper. FIG. 13 shows this aspect. In FIG. 13, a label carrying sheet 160 with release paper is supplied to a label superimposed body manufacturing apparatus 90 through a feed roll 162. In the feed roll 162, the release paper 164 is peeled off from the label carrier sheet 160 with release paper, and the label carrier sheet 166 without release paper is supplied to the label superimposed body manufacturing apparatus 90. The label superimposed body 170 is made by the above-described process in the label superimposed body manufacturing apparatus 90, and the remaining ear 174 is wound up through the feed roll 172.
[0042]
  In Japanese Patent Application No. 10-31630, the inventor of the present invention has proposed a method for manufacturing a label superposed body from a label carrying sheet with release paper. In this Japanese Patent Application No. 10-31630, the label is peeled off using the phenomenon that the label is peeled off from the release paper by abruptly changing the traveling direction of the label carrying sheet with release paper, and the labels are stacked as they are. This method can produce a label superimposed body very efficiently when the label size is relatively small, but when the label size is large, the label is bent by its own weight when peeled off from the release paper, and again the release paper. This may cause trouble in the process.
[0043]
  In the present invention, it is possible to produce a label superposed body with almost no trouble in the process regardless of the size of the label. The above-described embodiment shown in FIG. 13 in which the label carrying sheet with release paper is manufactured using the label superimposed body manufacturing apparatus 90 is particularly preferable when the size of the label is large.
[0044]
  The printing paper used in the present invention is not particularly limited, and may be transparent, translucent, or opaque, and may be selected from various papers such as cellophane paper, fine paper, art paper, craft paper, and synthetic paper, nonwoven fabric, and various synthetic resins. It may be a material such as a film. In addition, usually available tack paper, for example, SS fine tack paper manufactured by Lintec Corporation, SS foil tack paper, SS art tack paper, SS Glossack paper, high quality tack paper manufactured by Oji Tack, Miracoat tack paper, foil Tack paper and art tack paper can also be used. The printing paper may be already printed or may be in a blank state, but is preferably made of a material that can be printed on at least one side.
[0045]
  Further, in order to obtain a releasable printing paper surface, it is effective to form a release layer by applying an appropriate release agent to the surface. The release agent to be applied is not particularly limited as long as it has a property of smoothly peeling the adhesive surface of the label to be used. For example, silicon resin, cellulose resin, Alkit resin, acrylic resin, polyurethane resin, polyester resin and the like can be used. Particularly preferably, a silicon resin, a cellulose resin, an acrylic resin, or the like is used. Moreover, although the method to provide is not specifically limited, The method of apply | coating, transferring, and printing is mentioned. Alternatively, if a polyolefin film such as polyethylene or polypropylene, a silicone resin film, or the like is used for printing paper, the printing paper itself is excellent in releasability, so that it can be used as it is without providing a release agent. .
[0046]
  Moreover, the adhesive etc. which have been used with the conventional adhesive label which backed the release paper can be used for the adhesive concerning this invention. For example, an adhesive such as natural rubber, synthetic rubber, acrylic resin, polyvinyl ether resin, urethane resin, or silicon resin can be used. Particularly preferred is an acrylic resin-based pressure-sensitive adhesive, but the pressure-sensitive adhesive used in the present invention is exemplified here and is not limited to the type.
[0047]
  If necessary, the above-mentioned pressure-sensitive adhesive further includes a tackifier such as a terpene resin or a styrene resin, a filler such as silica, calcium carbonate or barium sulfate, a softener such as a plasticizer, an antioxidant such as anilide, and a crosslinking agent. An agent or the like may be blended.
[0048]
  A method for applying the pressure-sensitive adhesive layer is not particularly limited, and examples thereof include a method in which one or more of the above-mentioned pressure-sensitive adhesives are dissolved in a suitable solvent and a method in which the pressure-sensitive adhesive layer is dispersed or emulsified in a suitable medium. .
[0049]
  Although the embodiments of the present invention have been described in detail above, the present invention can be implemented in variously modified, modified, and modified embodiments based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
[0050]
