Description

  The present invention relates to a label roll body obtained by winding a label having no release mount (a label without a mount) around a winding core.

  In recent years, there is a case in which a non-mounting label without a peeling mount is used for the purpose of reducing labor for peeling the label from the peeling mount. The label without a mount includes a strip-shaped base material, a release agent layer formed on one surface of the base material, and an adhesive layer formed on the other surface of the base material.

  The strip-shaped label is wound around the outer periphery of the core and shipped as a label roll. Here, when printing on a label, a label printer is used. The label printer has a label feeding mechanism, and printing is performed on the label surface while pulling out the label.

  However, paying attention to the winding start portion on the core that is the base end side of the label, since the pressure-sensitive adhesive layer of the label is directed to the outer peripheral surface of the core, one turn on the base end side of the label is wound. It is in a state of being directly attached to the core. Therefore, just before the label runs out, trying to pull out the label will not work. In this case, problems occur such as the label itself being broken in the middle, or an overload being applied to the label feeding mechanism of the label printer, resulting in an error.

  In order to avoid the above problem, Patent Documents 1 and 2 propose that the adhesive layer side of the label is made one turn around the outer periphery of the core, and a notch device is used to make a cut at a place where the label has made more than one turn. Yes.

  However, in such a configuration, the label winding operation is interrupted after the label has been turned once, and the label winding operation is resumed after the cut is made. Such an operation is inefficient and is not suitable for producing a large amount of label rolls. Further, since the cutting operation by the cutting device is performed in the process of winding the label, there is a problem that the level of the cutting is likely to be unstable and the desired breaking level cannot always be obtained. Further, there is a problem that the label is wasted for the last one turn wound around the core.

  On the other hand, Patent Document 3 proposes a label roll in which a roll is formed with a label without a mount itself, based on the idea of eliminating the core. In this case, if the winding core is eliminated, the pressure-sensitive adhesive layer is exposed on the inner peripheral side of the label roll, which is inconvenient to handle. Therefore, non-adhesiveness is imparted to the portion corresponding to the inner peripheral side of the label roll.

  However, in such a structure, the operation | work which coat | covers a non-adhesive material only to the part corresponded to the innermost periphery of a label roll is needed. The label roll is formed in a continuous band shape, and coating the non-adhesive material only on the portion corresponding to the innermost circumference results in poor work efficiency and increases costs. That is, the label roll without the winding core cannot be provided at a low cost.

  The present invention does not cause the label to stick to the winding core over the entire circumference, allows the label to be used effectively, and can be provided at a low cost so that no special work is required on the label itself. It aims at obtaining a label roll body.

  In order to achieve the above object, in the first invention, a non-mounting label in which a release agent layer is provided on one surface of a belt-like substrate and an adhesive layer is provided on the other surface of the substrate, A cylindrical roll core around which a label without mount is wound, and the core is made of paper, and the label without mount is provided on the outer peripheral surface of the core. A release agent layer for facilitating peeling is provided, and the mountless label is wound with the outer peripheral surface side of the core as the other surface.

  According to the first invention, since the release agent layer is provided on the outer peripheral surface of the core, the label is released from the outer peripheral surface (release agent layer) of the core when the label is pulled out to the proximal end. Can be disengaged from. Thereby, it is possible to avoid the inconvenience that the label is stuck on the winding core and the label is broken or an overload is applied to the label feeding mechanism to cause an error.

  By the way, the above-mentioned effect can be obtained also by a conventional technique (see Patent Documents 1 and 2) in which a notch is provided on the base end side of the label and the label is separated from the core side by the notch. However, in this case, since the winding is temporarily stopped in the middle of the label winding process around the core and the label is cut, there is a possibility that problems such as reduction in work efficiency and instability of the cutting quality may occur. . In this respect, in the present invention, since it is not necessary to perform any processing on the label itself, the above-described effects can be obtained while avoiding such a problem peculiar to the label. Further, since the label is peeled off from the core at the base end, the label can be used up to the last round, and the label can be effectively used. Furthermore, since the release effect of the label is obtained by providing the release agent layer on an inexpensive paper core that is originally attached to the adhesive layer, the cost can be reduced. As described above, the label can be used effectively, and the cost can be reduced by eliminating the need for special work on the label itself.

  According to a second invention, in the first invention, the release agent layer of the core has a higher adhesive affinity with the adhesive layer than the release agent layer of the mountless label. It is characterized by that.

  According to the second invention, since the release agent layer of the core is set to have a higher adhesive affinity with the adhesive layer than the release agent layer of the label, the label is weak against the outer peripheral surface of the core. Can be bonded with adhesive strength. Thereby, the label can be smoothly wound around the core while the label can be pulled out to the last round.

  According to a third invention, in the first or second invention, the label is formed with a rupture portion extending in the width direction at predetermined intervals in the length direction, and the region divided by the adjacent rupture portions is 1 It is characterized by two label pieces.

  According to the third aspect, when the label is pulled out from the core, the label piece can be separated at the broken portion by applying tension to the label as it is pulled out. Here, when a breakage portion is provided on the label of the prior art (see Patent Documents 1 and 2), when the label is tensioned so that the label piece is separated at the breakage portion, the label is not broken at the breakage portion and is cut. There is a possibility of breaking at a part. In that respect, according to the present invention in which processing such as cutting is not performed on the label, such inconvenience does not occur, and thus each label piece can be separated to the end.

  According to a fourth aspect of the present invention, in each of the first to third aspects, the core is a multilayer structure formed by winding a plurality of base papers cut into a predetermined width into a spiral shape, and is disposed on the outermost periphery. A release agent layer for the core is formed on the surface of the base paper.

  According to the fourth invention, in the manufacturing stage of manufacturing the core, the release agent layer is formed on the surface of one of the plurality of base papers constituting the core, and the base paper is wound lastly to form the core. A release agent layer can be formed on the outer peripheral surface of the film. Thereby, compared with the case where a release agent layer is formed in the subsequent process on the outer peripheral surface of the core, the release agent layer can be formed easily and cleanly.

The perspective view of a label roll body. The perspective view of a core. (A) is sectional drawing of the base paper of a core, (b) is sectional drawing of a label.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. 1 is a perspective view of the label roll body, and FIG. 2 is a perspective view of the core. 3A is a cross-sectional view of the core paper of the core, and FIG. 3B is a cross-sectional view of the label.

  As shown in FIG. 1, the label roll body 10 includes a core 11 and a label 12 without a mount (hereinafter simply referred to as a label 12) wound around the core 11. The core 11 is made of paper and has a cylindrical shape. Specifically, as shown in FIG. 2, the core 11 is formed by winding a plurality of slit-shaped base papers 14 cut into a predetermined width while being compressed into a spiral shape (spiral shape). Thus, a multilayer structure is formed.

  A release agent layer 15 is formed on the entire outer peripheral surface of the core 11. The release agent layer 15 is formed by applying a silicone resin as a release agent to the outer peripheral surface of the core 11. Specifically, as shown in FIG. 3A, the release agent layer 15 is formed by applying a silicone resin to the surface of the base paper 14 disposed on the outermost periphery of the core 11. More specifically, in the manufacturing process of the core 11, silicon resin is applied to the surface of the base paper 14 disposed on the outermost periphery, and the applied base paper 14 is applied to the outermost periphery of the core 11 with the application surface facing the surface. By being wound, the release agent layer 15 is formed on the outer peripheral surface of the core 11. Note that it is not always necessary to use silicon resin as the release agent, and other resin materials such as fluororesin may be used.

  As shown in FIG. 3B, the label 12 includes a base material 17 formed in a strip shape, a release agent layer 18 formed on the surface of the base material 17, and an adhesive formed on the back surface of the base material 17. Layer 19. The base material 17 is formed of thermal paper (thermal paper) and has the same width dimension (length in the short direction) as the core 11.

  The base material 17 is provided with a plurality of fracture portions 21 at predetermined intervals (specifically, equal intervals) in the longitudinal direction. The fracture portion 21 is formed by perforations extending in the width direction of the base material 17. Note that the break portion 21 may be formed by cutting instead of the perforation. A region between adjacent break portions 21 in the base material 17 is a label piece 22. A plurality of label pieces 22 are provided across the entire length of the base material 17. Thereby, each label piece 22 is separable by the fracture | rupture part 21, respectively.

  The release agent layer 18 is formed by applying a silicone resin as a release agent to the surface of the substrate 17. The release agent layer 18 is formed over the entire surface of the substrate 17. As the release agent, it is not always necessary to use silicon resin, and other resin materials such as fluororesin may be used.

  The pressure-sensitive adhesive layer 19 is formed by applying an emulsion adhesive on the back surface of the substrate 17. The pressure-sensitive adhesive layer 19 is formed over the entire back surface of the substrate 17. In addition to the emulsion adhesive, a solvent-based or hot-melt adhesive can be used as the adhesive.

  Here, the release agent layer 18 of the label 12 is set to have a lower adhesive affinity with the adhesive layer 19 than the release agent layer 15 of the core 11. In other words, the release agent layer 15 of the core 11 has a greater adhesive affinity with the adhesive layer 19 than the release agent layer 18 of the label 12. This is because the release agent layer 15 of the core 11 is formed using a release agent (silicon resin) for heavy release, and the release agent layer 18 of the label 12 is formed using a release agent (silicon resin) for light release. Is realized.

  Next, how the label 12 is wound around the core 11 will be described.

  When the label 12 is wound around the core 11, first, one end (base end) in the length direction of the label 12 is arranged on the outer peripheral surface of the core 11, and in this state, the label 12 is positioned on the outer periphery of the core 11. It is wound around one while being pressed against the surface. In this case, as described above, the release agent layer 15 of the core 11 is set to have a relatively high adhesive affinity with the adhesive layer 19 of the label 12, so that the label 12 is weakly adhered to the outer peripheral surface of the core 11. Wrapping is performed in the state. Therefore, the label 12 can be smoothly wound around the core 11. Then, the remaining part of the label 12 is wound around the core 11, and the label roll body 10 is completed.

  Then, the effect | action of the label roll body 10 is demonstrated. Here, an operation when the label roll body 10 is set in the label printer and the label 12 is pulled out by the label feeding mechanism will be described.

  The label roll body 10 is set in a state where the core 11 is inserted into the supply reel of the label feed mechanism. The label 12 is pulled out from the core 11 as required by the label feeding mechanism, and then the label piece 22 is printed on the leading end of the label, and the printed label piece 22 is applied with tension on the label 12. It is cut off at the breaking portion 21. In this way, the label 12 is sequentially separated as the label piece 22 at the breaking portion 21 and pulled out to the base end side (in other words, the winding start side to the core 11). When the label 12 is pulled out to the base end side (for example, when the label 12 is wound around the core 11 by one turn), when the tension is applied to the label 12, the label 12 becomes the outer periphery of the core 11. It is peeled from the surface, that is, the release agent layer 15 and detached from the core 11. Thereby, it is possible to avoid the inconvenience that the label 12 is stuck to the core 11 and the label 12 is broken in the middle or an overload is applied to the label feeding mechanism and an error occurs.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  Since the core 11 around which the label 12 is wound is made of paper and the release agent layer 15 is provided on the outer peripheral surface of the core 11 so that the label 12 can be easily peeled off, when the label 12 is pulled out to the base end. The label 12 can be peeled off from the outer peripheral surface (release agent layer) of the core 11. Thereby, the above-mentioned inconveniences (such as the label 12 breaking in the middle) that may occur when the label 12 is attached to the core 11 can be avoided without performing any treatment on the label 12 side. Further, since the label 12 is peeled off from the core 11 at the base end, the label 12 can be used up to the last round, so that the label 12 can be effectively used. Further, since the release effect of the label 12 is obtained by providing the release agent layer 15 on the inexpensive paper core 11 that is originally attached to the adhesive layer 19, the cost can be reduced. .

  For the release agent layer 15 of the core 11, the adhesive affinity with the adhesive layer 19 was set higher than that of the release agent layer 18 of the label 12. In this case, since the label 12 can be adhered to the outer peripheral surface of the core 11 with weak adhesive force, the label 12 can be smoothly pulled out of the core 11 while the label 12 can be pulled out to the last round. You can start winding.

  Since the broken portion 21 extending in the width direction is formed at predetermined intervals in the length direction in the label 12, a part of the label (that is, the label piece 22) is applied by applying tension to the label 12 when the label 12 is pulled out from the core 11. Can be cut off at the breaking portion 21. Here, in the present label 12, in addition to the breakable portion 21, an easily breakable portion such as a notch or a perforation is not provided, so that a tension is applied to the label 12 to try to separate the label piece 22 at the breakable portion 21. At this time, the inconvenience that the label 12 is unexpectedly broken at the easily breakable portion does not occur. For this reason, it becomes possible to separate each label piece 22 without remaining.

  The core 11 is formed by spirally winding a plurality of base papers 14 cut to a predetermined width, and a release agent is formed on the surface of the base paper 14 disposed on the outermost periphery of the base papers 14. Layer 15 was formed. In this case, in the manufacturing stage for manufacturing the core 11, the release agent layer 15 is formed on the surface of the base paper 14 disposed on the outermost periphery, and the base paper 14 on which the release agent layer 15 is formed is wound to wind the core 11. A release agent layer 15 can be formed on the outer peripheral surface. Thereby, compared with the case where the release agent layer 15 is formed on the outer peripheral surface of the core 11 in a later step, the release agent layer 15 can be easily and cleanly formed.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the release agent layer 15 is formed by applying a silicone resin to the outer peripheral surface of the core 11 in the manufacturing process of the core 11. The release agent layer 15 may be formed by applying a silicone resin to the outer peripheral surface of the core 11. If it does so, it will become possible to form the release agent layer 15 by apply | coating a silicone resin to the ready-made core 11 (paper tube). The release agent layer 15 is not necessarily formed by applying a silicon resin, and may be formed by other methods such as dipping in a silicon resin.

  (2) In the above embodiment, the release agent layer 15 is formed on the entire outer peripheral surface of the core 11, but a portion where the release agent layer 15 is not formed may be provided on a part of the outer peripheral surface of the core 11. By doing so, since it becomes possible to adhere the label 12 to the outer peripheral surface of the core 11 with a weak adhesive force, the label 12 can be smoothly wound around the core 11 as in the above embodiment. .

  (3) You may attach the base end part (part of the winding start of the label 12) of the label 12 with respect to the outer peripheral surface of the core 11 using a slightly adhesive tape. Even in this case, the base end portion of the label 12 can be adhered to the outer peripheral surface of the core 11 with a weak adhesive force, and the label 12 can be smoothly wound around the core 11.

  (4) The label roll body 10 of the present invention can be used for other apparatuses having a label feeding mechanism such as a label applicator and a dispenser in addition to a label printer.
