  In this state, the user manually peels off the release material layer 151 from the print-receiving pressure-sensitive adhesive tape 150 (printing has not started yet), and the release material layer 154, the base material layer 153, and the pressure-sensitive adhesive layer 152 are removed. The leading end of the tape is attached to the core 41 of the winding mechanism 40. At this time, when the transport roller 12 is driven, the print-receiving adhesive tape 150 fed out by the rotation of the print-receiving tape roll R1 stored in the first storage unit 3 is transported forward (this embodiment). Equivalent to the transporting process). Then, an ink layer 155 by a desired printing is formed by the ink jet head 10a on the release agent layer 154 of the printed adhesive tape 150 to be conveyed to form a printed adhesive tape 150 ′ (in the printing process in this embodiment). Equivalent). When the printed adhesive tape 150 ′ that has been printed is further conveyed to the front side and conveyed to the peeling portion 17, the release material layer 151 is peeled off at the peeling portion 17, and the printed adhesive tape 150 ″ is printed. The peeled release material layer 151 is transported downward and introduced into the second storage unit 5 and wound inside the second storage unit 5 to form a release material roll R3.

  On the other hand, the printed adhesive tape 150 ″ from which the release material layer 151 has been peeled off is irradiated with ultraviolet rays (UV) to the ink layer 155 by the UV irradiator 50, and the ultraviolet curable resin contained in the ink layer 155. After that, the printed adhesive tape 150 ″ is further conveyed forward and introduced into the third storage unit 4, and a winding mechanism in the third storage unit 4 is used. 40 is wound around the outer periphery of the core 41 to form a printed tape roll R2 (corresponding to the winding process in this embodiment). At that time, the cutter mechanism 30 provided on the downstream side (that is, the front side) in the transport direction cuts the printed adhesive tape 150 ″. Thus, it is wound around the printed tape roll R2 at a timing desired by the user. The printed adhesive tape 150 ″ is cut, and the printed tape roll R 2 can be taken out from the third storage unit 4 after cutting.

  In the transport path of the printed tape 150 ″, it is on the downstream side of the irradiation position by the UV irradiator 50, and after making a round along the circumferential direction after joining the outer peripheral side of the printed tape roll R2, it is made again. A drying means (not shown) such as a heater or a warm air fan is provided at an appropriate position before reaching the joining position. At least the printed tape 150 ″ is printed on the tape roll. The ink layer 155 cured by the UV irradiation is dried before being wound around the outer peripheral side of R2.

  At this time, a chute 15 (see FIG. 2) is arranged to switch the transport path of the printed adhesive tape 150 ″ between the side toward the printed tape roll R2 and the side toward the discharge port (not shown). That is, by switching the tape path by the switching operation of the chute 15 by a switching lever (not shown), the printed tape 150 ″ after printing is wound in the third storage portion 4 as described above. Without rotating, the housing 2 may be discharged out of the housing 2 as it is from a discharge port (not shown) provided on the second opening / closing cover 8b side, for example.

<Control system>
Next, the control system of the adhesive tape printer 1 will be described with reference to FIG. In FIG. 4, the adhesive tape printer 1 includes a CPU 212 that constitutes a calculation unit that performs a predetermined calculation. The CPU 212 is connected to the RAM 213 and the ROM 214. The CPU 212 performs signal processing in accordance with a program stored in advance in the ROM 214 while using the temporary storage function of the RAM 213, thereby controlling the entire adhesive tape printer 1.

  Further, the CPU 212 controls the driving of the motor M1 for driving the conveying roller M1 that drives the conveying roller 12 and the motor M2 for the adhesive winding that drives the core 41 of the winding mechanism 40. The motor drive circuit 219 for performing the above, the motor drive circuit 220 for performing the drive control of the release paper winding motor M3 for driving the release material roll R3, and the energization control for the piezoelectric actuator (not shown) of the inkjet head 10a.

The printed adhesive tape 150 ″ can be realized.

  In the present embodiment, in particular, the UV irradiator 50 is disposed on the downstream side of the inkjet head 10 a and the upstream side of the winding mechanism 40 in the tape conveyance path by the conveyance roller 12. As a result, the printed adhesive tape 150 ″ is irradiated with ultraviolet rays before being wound around the printed tape roll R 2, so that the ultraviolet rays can be irradiated with a relatively strong intensity without being blocked. The UV curable resin can be reliably cured.

  In the present embodiment, in particular, the UV irradiator 50 is disposed on the upstream side of the peeling portion 17 in the tape conveyance path by the conveyance roller 12. In this way, the winding is performed in a state where the curing of the ultraviolet curable resin is reliably completed as a result of the ultraviolet irradiation being performed further upstream than the peeling portion 17 positioned on the upstream side of the winding mechanism 40.

  That is, in the same manner as described above, the user manually peels off the release material layer 151 from the printing adhesive tape 150, and the tip of the tape composed of the release agent layer 154, the base material layer 153, and the adhesive layer 152 is wound around the above-described winding. It is attached to the core 41 of the take-off mechanism 40. When the transport roller 12 is driven, the print-receiving adhesive tape 150 fed out by the rotation of the print-receiving tape roll R1 is transported to the front side (corresponding to the transport process in this embodiment), and the print-receiving adhesive tape 150 is peeled off. A desired print is formed on the agent layer 154 by the transfer layer 155 ′ by ink transfer by the thermal head 11 (corresponding to a printing step in this embodiment), and the pressure-sensitive adhesive tape 150 ′ is printed. The printed adhesive tape 150 ′ that has been printed is further conveyed forward, and the release material layer 151 is peeled off at the peeling portion 17 to form a printed adhesive tape 150 ″. The peeled release material layer 151 is peeled off. Is wound in the second storage portion 5 to form the release material roll R3, as described above, and the printed adhesive tape 150 ″ from which the release material layer 151 has been peeled off is the UV irradiator 50 as described above. As a result, the transfer layer 155 ′ is irradiated with ultraviolet rays (UV), and the ultraviolet curable resin contained in the transfer layer 155 ′ is cured (corresponding to the irradiation step in this embodiment). Thereafter, the printed adhesive tape 150 ″ is further conveyed forward and wound around the outer periphery of the winding core 41 of the winding mechanism 40 to form a printed tape roll R2 (winding in this embodiment). Note that the adhesive layer 152, the base material layer 153, and the release agent layer 154 constituting the printed adhesive tape 150 ″ wound around the printed tape roll R2 are included in the tape body in the present embodiment. It corresponds. Thereafter, the cutter mechanism 30 cuts the printed adhesive tape 150 ″. At this time, the transport path of the printed adhesive tape 150 ″ may be switched by the chute 15 as described above.

<Control system>
A control system of the adhesive tape printer 1 is shown in FIG. 9, in this embodiment, in place of the inkjet head control circuit 300 that controls the inkjet head 10a in the configuration of the control system of the first embodiment shown in FIG. 4, energization of the heating elements of the thermal head 11 is performed. A thermal head control circuit 221 that performs control is provided. The other configuration is the same as that of FIG.

<Transfer with ink ribbon>
Next, details of the transfer of ink from the ink ribbon IB, which is one of the features of this embodiment, will be described.

  The ink ribbon IB fed out from the ribbon supply roll R <b> 4 contacts the lower part of the thermal head 11. At this time, as shown in FIG. 10, the ink ribbon IB is provided adjacent to the ribbon base material layer 155a and one side (the lower side in the figure) in the thickness direction of the ribbon base material layer 155a. An undercoat layer 155b that is melted and separated from the ribbon base material layer 155a is provided adjacent to one side in the thickness direction of the undercoat layer 155b (that is, the thickness direction of the overcoat layer 155d and the undercoat layer 155b) An ink layer 155c made of, for example, a pigment that gives a visual color as a print (located in the middle) and an overcoat layer 155d that is provided adjacent to one side in the thickness direction of the ink layer 155c and adheres to the transfer target And a laminated structure (in this example, four layers). In this embodiment, the overcoat layer 155d has a relatively low value of a solubility parameter value (hereinafter referred to as “SP value” as appropriate) of, for example, 6 or more and 10 or less.

  In the ink ribbon IB having the above configuration, the undercoat layer 155b is melted by receiving heat from the thermal head 11, so that the undercoat layer 155b, the ink layer 155c, and the overcoat layer 155d are melted from the ribbon base material layer 155a. The transfer layer 155 'made of is separated. Then, the overcoat layer 155d side of the transfer layer 155 ′ is transferred and adhered to the release agent layer 154 of, for example, an olefin resin type of the print-receiving adhesive tape 150 to be transferred (FIG. 10A and FIG. 10). b)). As a result, printing is performed on the release agent layer 154 of the printing adhesive tape 150 by the ink ribbon IB, and the printed adhesive tape 150 ′ is generated.

<Improvement of adhesion of transfer layer with UV curable resin>
Here, the printed adhesive tape 150 ″ produced from the printed adhesive tape 150 ′ having the laminated structure shown in FIG. 10B (with the release material layer 151 peeled off) is shown in FIG. As shown, the release agent layer 154, the tape base layer 153, and the adhesive layer 152 are included in this order, and as a result, the transfer layer 155 'is transferred to the printed tape roll R2 of the present embodiment. In this portion, the surface on one side in the thickness direction (the lower side in the figure) of the transfer layer 155 ′ and the adhesive layer 152 are in contact with the radial direction of the tape roll R2 with print. If the adhesiveness between ′ and the release agent layer 154 is small, when the printed adhesive tape 150 ″ is fed from the printed tape roll R2 and used as described above, it is transferred from the ink ribbon IB and formed. The above transfer layer 155 'is peeled again to the adhesive layer 152 side, it may adversely affect printing.

  Therefore, in this embodiment, the transfer layer 155 ′ (specifically, at least one of the undercoat layer 155b, the ink layer 155c, and the overcoat layer 155d) has an ultraviolet curable resin layer that is cured by ultraviolet irradiation. Yes.

  FIG. 11 shows variations in the pattern of containing the ultraviolet curable resin with respect to the undercoat layer 155b, the ink layer 155c, and the overcoat layer 155d constituting the transfer layer 155 ′ that can be considered in the present embodiment.

  In FIG. 11, in the pattern A, the undercoat layer 155b does not contain an ultraviolet resin, the ink layer 155c contains an ultraviolet curable resin, and the overcoat layer 155d does not contain an ultraviolet curable resin.

  Similarly, in pattern B, the undercoat layer 155b contains an ultraviolet resin, the ink layer 155c also contains an ultraviolet curable resin, and the overcoat layer 155d does not contain an ultraviolet curable resin. In the pattern C, the undercoat layer 155b does not contain an ultraviolet resin, the ink layer 155c contains an ultraviolet curable resin, and the overcoat layer 155d also contains an ultraviolet curable resin.

  In the pattern D, the undercoat layer 155b contains an ultraviolet resin, the ink layer 155c also contains an ultraviolet curable resin, and the overcoat layer 155d also contains an ultraviolet curable resin. In the pattern E, the undercoat layer 155b contains an ultraviolet resin, the ink layer 155c contains no ultraviolet curable resin, and the overcoat layer 155d contains no ultraviolet curable resin.

  In the pattern F, the undercoat layer 155b contains an ultraviolet resin, the ink layer 155c contains no ultraviolet curable resin, and the overcoat layer 155d contains an ultraviolet curable resin. In the pattern G, the undercoat layer 155b contains no ultraviolet resin, the ink layer 155c contains no ultraviolet curable resin, and the overcoat layer 155d contains an ultraviolet curable resin.

  Then, the printed adhesive tape 150 ″ on which the transfer layer 155 ′ containing the ultraviolet curable resin is formed as described above is irradiated with ultraviolet rays by the UV irradiator 50 as described above, whereby the transfer layer 155 ′. The ultraviolet curable resin layer adheres firmly to the release agent layer 154. This makes it possible to prevent the transfer layer 155 'from being peeled off.

  According to the study by the present inventors, among the patterns A to G, at least one of the ink layer 155c and the undercoat layer 155b includes an ultraviolet curable resin layer (pattern A to pattern F). ) Is particularly preferable from the viewpoint of surely realizing strong adhesion.

<Improved transferability by setting SP value>
On the other hand, as shown in FIG. 10A, the transfer layer 155 'includes an undercoat layer 155b, an ink layer 155c, and an overcoat layer 155d in this order. That is, at the time of transfer from the ink ribbon IB, the overcoat layer 155d of the transfer layer 155 'adheres adjacent to the release agent layer 154, and transfer is performed. In order to improve the transferability at this time, it is necessary to increase the adhesion between the adjacent release agent layer 154 and the overcoat layer 155d. It is preferable that the difference from the SP value of the coat layer 155d is relatively small (see FIG. 12).

  Here, as described above, the release agent layer 154 is made of an olefin resin-based release (from the viewpoint of improving the peelability so that the printed adhesive tape 150 ″ can be peeled off from the printed tape roll R2 at a lighter load during use). In this embodiment, the overcoat layer 155d is also used for normal tape printing, and is composed of an acrylic resin-based release agent having an agent or a long-chain alkyl group. As in the case of the ink ribbon IB, those having an SP value (solubility parameter value) exceeding 11 are not used, and those having an SP value of 6 or more and 11 or less are employed (see FIG. 12). Thus, the adhesion between the overcoat layer 155d and the release agent layer 154 is increased, and the transfer layer 155 'is transferred from the ink ribbon IB. It is possible to improve the sex.

<Effects of ink ribbon of this embodiment>
As described above, the ink ribbon IB in the present embodiment includes the ultraviolet curable resin in at least one of the undercoat layer 155b, the ink layer 155c, and the overcoat layer 155d constituting the transfer layer 155 ′, and Since the SP value of the overcoat layer 155d is 6 or more and 11 or less, the transferability from the ink ribbon IB is improved while preventing the printing contents from being adversely affected when the overcoat layer 155d is fed from the printed tape roll R2. It is possible to realize a printed adhesive tape 150 ″ having optimum characteristics.

  In the present embodiment, in particular, at least one of the ink layer 155c and the undercoat layer 155b contains an ultraviolet curable resin. This has the following significance. That is, in the printed tape roll R2, as shown in FIG. 10C, the transfer layer 155 is in direct contact with the adhesive layer 152 in the radial direction of the roll at the portion where the transfer layer 155 'is transferred. The undercoat layer 155b is located on the surface of the other side in the thickness direction (the upper side in FIG. 10). Therefore, it is most effective to include an ultraviolet curable resin in the undercoat layer 155b to prevent the peeling. On the contrary, even if an ultraviolet curable resin layer is included in the overcoat layer 155d located on the surface of the transfer layer 155 ′ on one side in the thickness direction (the lower side in FIG. 10), the other undercoat layer 155b is peeled off. The above-mentioned peeling prevention effect is small. As described above, by providing an ultraviolet curable resin layer on at least one of the ink layer 155c and the undercoat layer 155b other than the overcoat layer 155d, the printed content is adversely affected when the printed tape roll R2 is fed out. It can be surely prevented.

<Effects of Print Forming Method and Printed Tape Roll of Present Embodiment>
As described above, the printed adhesive tape 150 ″ is transferred to the release agent layer 154, the base material layer 153, and the adhesive layer 152 by transfer from the ink ribbon IB in the printing process, as described above. The layer 155 'is formed, and the user sets the printed tape roll R2 around which the printed adhesive tape 150 "is wound in the winding process as described above at an appropriate timing. Then, after taking out from the third storage portion 4, a printed adhesive tape 150 ″ of a desired length is drawn out from the printed tape roll R 2 and attached to an appropriate adherend, for example, for a label or packing At this time, as already described, the printed adhesive tape 150 ″ has the release agent layer 154, the base material layer 153, and the adhesive layer. Adhesive layer 152 is a laminated structure comprising in this order. By providing the release agent layer 154 on the other side in the thickness direction of the base material layer 153 in the printed adhesive tape 150 ″ (that is, the side opposite to the side to be adhered to the adherend), the label or sealing is performed as described above. When used as a material, dirt and dust are less likely to adhere to the surface, and antifouling properties can be maintained.

  In the present embodiment, as described above, in the irradiation process by the UV irradiator 50, the ultraviolet curable resin provided in the transfer layer 155 ′ is irradiated with ultraviolet rays to cure the ultraviolet curable resin. Thus, the transfer layer 155 ′ can be firmly adhered to the release agent layer 154. As a result, it is possible to prevent the transfer layer 155 ′ from being peeled off from the release agent layer 154 when the tape roll R <b> 2 is fed out.

  As described above, in the print forming method of the present embodiment and the printed tape roll R2 generated thereby, it is applied while preventing the printing from being adversely effected when it is fed out from the printed tape roll R2. It is possible to realize a printed adhesive tape 150 ″ having optimum characteristics that can maintain antifouling properties when used.

  In this embodiment as well, as in the first embodiment, the UV irradiator 50 is located on the downstream side of the inkjet head 10a and the upstream side of the take-up mechanism 40 in the tape conveyance path by the conveyance roller 12. It arrange | positions upstream from the peeling part 17. FIG. Thereby, the same effect as described above can be obtained.

<Third Embodiment>
A third embodiment of the present invention will be described with reference to FIGS. In this embodiment, in the configuration of the first embodiment, instead of one inkjet head 10a, a first inkjet head that forms an anchor layer (described later) and a second inkjet head that forms a UV ink layer are two. It is embodiment which provides one. Parts equivalent to those in the first embodiment and the second embodiment are denoted by the same reference numerals, and description thereof is omitted or simplified as appropriate.

<Schematic configuration of adhesive tape printer>
