Description

  The present invention relates to a configuration of a cartridge containing a tape-like recording medium to be transported, and more specifically, a protective tape is applied to a surface of a recording medium in a state where ink discharged for printing does not bleed. The present invention relates to a cartridge structure that can be attached to an ink jet printer that can be matched.

  2. Description of the Related Art Conventionally, it is well known to produce a printer in which characters, images, and the like are printed on the surface of a tape-shaped recording medium and a transparent laminate film is bonded to the printing surface by an ink jet printer.

  In this case, since the ink ejected from the inkjet head onto the surface of the recording medium is in the form of droplets, if the laminate film is pasted immediately after printing, the ink oozes out on the printing surface that is not dry, and the printed surface is finished beautifully.

  As a conventional technique for solving this problem, for example, in Patent Document 1, an adhesive material layer that is preliminarily applied to the back surface of the laminate film and bonded to the surface of the recording medium is formed of a material having high water absorption. Propose to do.

  In this case, when the bonding is performed, the moisture of the ink that has not yet dried on the printing surface is absorbed by the water-absorbing pressure-sensitive adhesive layer to eliminate ink bleeding.

  On the other hand, Patent Document 2 proposes that a printing base tape as a recording medium and / or a protective tape to be bonded to the printing surface of the printing base tape is made of a gas permeable material. In this case, even if the ink drying is incomplete, the gas evaporated by the drying of the ink passes through the tape of the gas permeable material and then comes out from the bonded surface. Air bubbles do not accumulate.

  Further, Patent Document 3 discloses a special cross-sectional structure of a tape-shaped recording medium. That is, the back surface of the ink absorption layer defining the printing surface is supported by a support layer made of PET film, and the back surface of the support layer is covered with an adhesive layer and release paper, while the surface of the ink absorption layer is Cover with a liquid-permeable thermal laminate layer. Then, ink droplets ejected from the ink jet pass through the thermal laminate layer and adhere to the ink absorbing layer. If the heat laminating layer is heated after this printing, once it is melted and then cured, the heat laminating layer changes to a non-liquid permeable transparent layer.

In Patent Documents 1 and 4, a tape-like recording medium is housed in a cartridge while being wound around a spool, and the cartridge is detachably mounted in a housing portion of a printer device. A configuration for drawing out is disclosed.

The protective tape or the double-sided adhesive tape can be bonded together in a state where the ink is surely dried with only the specific configuration, and the printed surface is finished beautifully.

  Next, an embodiment embodying the present invention will be described. FIG. 1 is a schematic view of an ink jet printer that performs printing with an ink jet head while pulling out a recording medium from a cartridge containing a tape-shaped recording medium and a protective tape for bonding.

  In FIG. 1 as the first embodiment, in a cartridge 1, a printing tape 2 as a recording medium and a protective tape 3 for bonding to the surface (printing surface) of the printing tape 2 are spools 4 respectively. 5, the printing tape 2 passes between the light projecting part 6a of the light transmission type sensor part 6 and the frame parts 7 and 7 for arranging the light receiving part 6b, and is in the form of a roller or the like. A predetermined character / image is printed on the surface of the printing tape 2 when passing through the front surface of the printing unit 10 where the inkjet head unit 9 is disposed via the unit 8. Thereafter, the back surface of the protective tape 3 and the front surface of the printing tape 2 are bonded to each other at the position of the pressing roller 11 and the driving roller 12 as a pair of conveying rollers, and transferred to a tape printer (not shown). The printed tape is cut to a required length by a cutter (not shown) provided at the outlet of the tape printer. Accordingly, the cartridge 1 is provided with an opening portion in which the ink jet head portion 9 is fitted and accommodated at a location where the printing tape 2 passes through the printing portion 10.

  In this case, the transfer speed of the printing tape 2 at the location of the pressing roller 11 and the driving roller 12 as the conveying roller pair is V, and the time T required to dry after discharging ink to the surface of the printing tape 2 is as follows: The distance from the printing part 10 corresponding to the nozzle part of the inkjet head part 9 to the bonding part 14 of the printing tape 2 and the protective tape 3 (a line passing through both rotation axes of the pressing roller 11 and the driving roller 12). When L1, L1 ≧ V × T is set.

  In general, the ink drying time T varies depending on the ink material used. Further, the dimensions of the cartridge used in the ink jet printer, and thus the distance L1 from the printing unit 10 to the bonding unit 14 are slightly different depending on the manufacturers, but not greatly different. Therefore, as a practical matter, the transfer speed V of the printing tape 2 is designed to be slow for those having a long ink drying time T. However, since the printing efficiency is deteriorated when the transfer speed V is extremely slow, the most preferable relationship is that the distance L1 from the printing unit 10 to the bonding unit 14 is set until the ink discharged to the printing unit 10 is dried. Is set to be substantially equal to a value obtained by multiplying the time T by the transfer speed V of the printing tape 2.

  FIG. 2 shows one embodiment of the cross-sectional form of the printing tape 2 and the protective tape 3. In this embodiment, the printing tape 2 is a printing substrate 201 made of a synthetic resin film such as polyethylene terephthalate (PET film), polyvinyl chloride, or polypropylene resin, which has been subjected to a surface treatment that allows ink to adhere and dry easily. A release paper 203 is attached to the back surface of the adhesive tape 202 through the adhesive layer 202. The protective tape 3 as a bonding tape has a transparent adhesive layer 302 applied in advance to the back surface, and an ultraviolet absorber is kneaded. It consists of a non-liquid-permeable cover tape 301 made of a transparent PET film or the like.

  Accordingly, while the leading end of the printing tape 2 and the protective tape 3 is sandwiched at the pressing point (bonding portion 14) between the pressing roller 11 and the driving roller 12 in the cartridge 1, the cartridge 1 is moved leftward in FIG. In the printing unit 10, the ink 15 is ejected from the inkjet head unit 9 onto the surface of the printing substrate 201 in the printing tape 2 to print a normal image of characters and images. The ink 15 is dried before being transferred to the bonding unit 14, and the bonding tape 14 covers the print tape 1 so that the surface of the dried ink 15 is covered with the protective tape 3. They are pasted together. Thereafter, the bonded tape is cut into a predetermined length by a cutter device (not shown), and then the release paper 203 is peeled off, and the back surface side of the printing tape 2 is attached to a necessary portion.

  In this embodiment, since the portion of the ink 15 on the surface of the printing tape 2 is covered with the protective tape 3, the printing surface does not directly touch other things, the printed part does not peel off, and is resistant to water wetting. Also resistant to fading caused by ultraviolet rays.

  In the embodiment shown in FIG. 3, the printing tape 2 absorbs ultraviolet rays on the surface of the polyethylene terephthalate film (PET film), polyvinyl chloride, polypropylene resin, etc., which has been subjected to a surface treatment that allows easy adhesion of ink and drying, as described above. It is a printing substrate 201 made of a transparent synthetic resin film in which an agent is kneaded, and may be transparently colored.

  And as the double-sided adhesive tape 16, adhesive layers 162 and 163 are applied and formed on both front and back surfaces of the base tape 161, and one of the adhesive layers 162 is coated with a tape-shaped release paper 164 in advance. The base tape 161 may be an opaque material, a translucent material, or a coloring material.

  On the surface (printing surface) of the printing tape 2, a character / screen mirror image is printed by the printing unit 10, and then the printing tape is pressed at a pressing point (bonding unit 14) between the pressing roller 11 and the driving roller 12. 2 and the left side of the double-sided adhesive tape 16 sandwiched between them, the printed surface can be adhered and covered with the adhesive layer 163 of the double-sided adhesive tape 16. The tape thus bonded may be cut to a predetermined length with a cutter (not shown), the release paper 164 may be peeled off, and the adhesive layer 162 of the double-sided adhesive tape 16 may be adhered to the portion to be applied.

  4 and 5 show still another embodiment, and the surface of the printing tape between the printing unit 10 by the inkjet head unit 9 and the pressing point (bonding unit 14) between the pressing roller 11 and the driving roller 12 is shown. A blower opening 17 serving as a dry air blowing section is opened so as to face the (printing surface), and air is supplied to the blower opening 17 through a duct 19 from a blower fan 18 disposed at an appropriate location of the inkjet printer. . The wind in this case may be cold air or warm air that does not cause the printing tape 2 made of synthetic resin film to be carelessly stretched. This drying air is blown onto the surface (printing surface) of the printed printing tape 2 so that the discharged ink 15 can be quickly dried.

  As described above, since the drying time T of ink can be drastically shortened by blowing dry air, when the distance from the printing unit 10 to the bonding unit 14 is the same as that in the first embodiment. Thus, it is possible to increase the transfer speed V of the printing tape 2 and greatly improve the printing speed.

  FIG. 6 shows a back-up tape 20 having a width dimension W2 (> W1) in which a substrate or coating layer having high water absorption (ink absorbability) is applied to the back surface of the printing tape 2 having a width dimension W1. Both edges in the width direction of the backup tape 20 protrude beyond both edges in the width direction of the printing tape 2. In this case, the printing tape 2 and the backup tape 20 may be simultaneously wound around the spool 4 and sent to the printing unit 10. Examples of materials having high water absorption (ink absorption) include polyvinyl alcohol polymers, water-soluble films of crosslinked polyacrylamide polymers, and crosslinked polyacrylate resins.

  As described above, if the tape is supported by the backup tape 20 protruding from both edges in the width direction of the printing tape 2, when the ink is discharged over the entire width of the printing tape 2 and the full width is applied, the printing is performed. Since the ink is ejected to the portion beyond the width of the tape 2, the ink ejection portion that protrudes beyond the both edges in the width direction of the printing tape 2 is received on the surface of the backup tape 20, so that the cartridge 1 and the platen It is possible to reliably prevent the surface of a component or the like from being stained with ink. Further, it is possible to prevent the ink once attached to the printer parts such as the platen as described above from adhering again to the back surface of the printing tape 2 to be transferred and causing a printing defect.
