Description

  The present invention relates to a printing roll paper such as a label, a ticket, and a tag, and a manufacturing method thereof.

In many cases, labels, tickets, tags, receipts and the like are wound around a cylindrical branch pipe, provided as a roll paper for printing, and issued by printing various information with an electronic printer.
FIG. 8 shows a perspective view of a label roll 41 as an example of printing roll paper. The label roll 41 winds around a cylindrical branch pipe 48 a continuous label body 46 in which labels 45 each consisting of a label base material 43 and an adhesive layer 44 are arranged on a release surface of a long strip-like release paper 42 at regular intervals. It is a thing.

  FIGS. 9A and 9B are schematic side views of the electronic printer 50. The electronic printer 50 includes a roll paper supply unit 51 and a printing unit 61 provided in a housing 52. A label roll 41 is rotatably supported on the shaft 55 of the roll paper supply unit 51. A guide bar 56, a paper sensor 57 for detecting the presence / absence of the label continuous body 46, and a pitch sensor 58 for detecting a label interval are attached along the travel path of the label continuous body 46. The downstream printing unit 61 includes a platen roller 62, a thermal head 63 that presses and holds the label continuous body 46 together with the platen roller 62, and a cutter unit 64 downstream thereof. The housing 52 is provided with an issue port 65 adjacent to the cutter unit 64.

  When the platen roller 62 rotates, the label continuum 46 unwound from the label roll 41 reaches the printing unit 61 via the guide bar 56, the paper sensor 57, and the pitch sensor 58. Will print images such as characters and barcodes. The label 45 on which printing has been performed is discharged continuously from the issuing port 65 while being continuous or cut by the cutter unit 64.

  As shown in FIG. 9B, when all the labels 45 are unwound from the label roll 41, the end side of the label continuous body 46 hangs down, the paper sensor 57 detects the end of the label roll 41, and the printer 50 Stop.

  Incidentally, as shown in FIG. 10, the conventional label roll 41 is wound around the branch pipe 48 with an adhesive tape 49 or a double-sided tape, and the branch pipe 48 is rotated. When printing is issued by the printer 50, the last label 45 of the label continuous body 46 is unwound and the adhesive tape 49 is peeled off from the branch pipe 48. However, the adhesive tape 49 may not be smoothly peeled off from the branch pipe 48 even when the last label 45 is unwound. As shown in FIG. 11, when the branch pipe 48 is made of paper, the surface layer is peeled off, and the paper sensor 57 mistakenly recognizes the presence or absence of the label continuous body 46 due to the peeled pieces 48a, and the printer 50 malfunctions. May cause abnormal running. Further, the debris 48a and the adhesive tape 49 may contaminate the detection unit and the conveyance path of the paper sensor 57 and the pitch sensor 58, or may be sandwiched between the platen 62 and the thermal head 63 to cause contamination or damage. .

A method for producing a roll paper for printing, characterized in that the end of the continuous paper for printing is temporarily pressed against the hot melt adhesive on the surface of the branch pipe and then temporarily attached, and then the continuous paper is wound by rotating the branch pipe In

  The gist of the invention described in claim 4 resides in a method for producing a printing roll paper, wherein the hot melt adhesive according to claim 3 has a viscosity of 500 to 12000 cps.

  The gist of the invention described in claim 5 is that the viscosity when press-bonding the continuous paper for printing to the hot melt adhesive on the surface of the branch pipe is different from the viscosity when applying the hot melt adhesive according to claim 3. It exists in the manufacturing method of the roll paper for printing characterized by being 120% or more.

  According to the printing roll paper and the printing roll paper manufacturing method of the present invention, the end of the roll paper can be smoothly separated from the branch pipe when the printing roll paper is used up. By reliably detecting the end of the roll paper, it is possible to avoid malfunction of the printer and avoid trouble of the printer.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of the printing roll paper of the present invention. In FIG. 1, a label roll 1 will be described as an example of printing roll paper. The label roll 1 is obtained by winding a continuous label 6 having a label 5 made of a label base material 3 and an adhesive layer 4 on a release surface of a long strip-like release paper 2 around a cylindrical branch pipe 8. Is.

  FIG. 2 shows a side view of the main part near the branch pipe 8. An end 6 a of the label continuous body 6 is temporarily attached with a branch pipe 8 and a hot melt adhesive 10.

  The release paper 2 can be 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.

  The type and material of the label substrate 3 are not particularly limited, such as paper or a synthetic resin film, and those generally used as adhesive paper can be used. 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 also be used. Thermal paper may be used.

  As the pressure-sensitive adhesive 4, for example, a hot-melt system (using thermoplasticity) emulsion system (pressure-sensitive adhesive dispersed in water), a solvent system (pressure-sensitive adhesive dissolved in a solvent) or the like can be used. As the material, an adhesive such as synthetic rubber, natural rubber, acrylic resin, polyvinyl ether resin, urethane resin, or silicone resin can be used.

  When the roll paper for printing is other than a label, for example, a ticket, a tag, or a receipt, a paper or a film having a material and thickness suitable for each application may be used, and the invention is not limited.

  As the hot melt adhesive 10, for example, an ethylene vinyl acetate copolymer system, a polyamide system, a polyolefin system, or a synthetic rubber system can be used. What is necessary is just to have a viscosity of 500 to 12000 cps when coating by heating and melting.

  This label roll 1 is manufactured as follows. As shown in FIG. 3, a hot melt gun 9 is used to apply a hot melt adhesive 10 on the surface of the branch pipe 8 along the axial direction. Next, as shown in FIG. 4, the end 6 a of the label continuous body 6 is pressed against the hot melt adhesive 10 of the branch pipe 8 and temporarily attached from a master roll (not shown) after the label processing is completed. In this state, the branch pipe 8 is rotated to start winding, and when it is wound up to a predetermined length, the printing roll paper (label roll 1) of the present invention is completed.

  Here, since the viscosity is relatively low immediately after the hot melt adhesive 10 is applied, the hot melt adhesive 10 penetrates into the fine irregularities on the surface of the branch tube 8 and adheres strongly. When the label continuous body 6 is pressed and temporarily attached, the temperature of the hot melt pressure-sensitive adhesive 10 decreases and the viscosity increases as time elapses. Therefore, the label continuous body 6 and the hot melt adhesive 10 Is weaker than that between the branch pipe 8 and the hot melt adhesive 10. If the viscosity at the time of pressing and sticking the label continuous body 6 is 1.2 times or more (120% or more) with respect to the viscosity immediately after the hot melt adhesive 10 is applied to the branch pipe 8, there is a difference in the adhesive strength between them. Is likely to occur. It is more preferable if the viscosity ratio is 2 times or more.

  The operation of the label roll 1 thus created will be described with reference to FIGS. 5 (a) and 5 (b). The components of the printer 50 shown in these drawings are given the same reference numerals as those in FIGS. 9A and 9B used for the description of the prior art, and the description thereof is omitted.

  When the end of the label continuous body 6 approaches as shown in FIG. 5A, the adhesive force between the branch pipe 8 and the hot melt adhesive 10 is larger than the adhesive force between the label continuous body 6 and the hot melt adhesive 10. Therefore, the label continuous body 6 and the branch pipe 8 are separated from the interface between the label continuous body 6 and the hot melt adhesive 10 as shown in FIG. This state is immediately detected by the paper sensor 57, and the printer 50 stops operating. A broken piece of the branch pipe 8 is not dragged to the label continuous body 6 to cause a problem.

  FIG. 6 is another embodiment of the present invention. As shown in the figure, the hot melt adhesive 10 may be applied in the form of dots. The pattern of coating is arbitrary.

  Moreover, as shown in FIG. 7, you may wind up in the shape of a roll by making the front and back of the label continuous body 6 reverse. In this case, the label base material is temporarily attached to the branch pipe 8 with the hot melt adhesive 10.

  Note that the present invention is not limited to the above-described embodiments, and it is obvious that the embodiments can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to a number, position, shape, and the like that are suitable for implementing the present invention.
