Description

  The present invention relates to a multicolor thermal transfer printer for producing a transfer foil by thermally transferring a multicolor fine image onto a continuous original fabric such as a resin film or a foil.

  The image printing ink is transferred to the surface by injecting the molten synthetic resin into the mold after the transfer foil with the image printed with the thermoplastic resin ink is pasted into the mold. An injection-molded product can be manufactured. After the injection molded product is taken out from the mold, the base material of the transfer foil is removed to complete the injection molded product with an image displayed on the surface.

  In general, a gravure printing method or the like is used for manufacturing the transfer foil. However, in the case of a small number of copies, it is preferable to use a printer because it is possible to reduce the cost. It is considered desirable to use a thermal transfer printer that uses a thermoplastic resin ink. This is because the thermoplastic resin ink is not easily distorted by heat when transferred to an injection-molded product, and the printed image has high durability.

  In this thermal transfer printer, a plurality of thermal transfer units each printing an image of a predetermined color ink are arranged in series, and the film or the like is transferred from the upstream thermal transfer unit to the downstream thermal transfer unit. While running, each color transfer ink image is printed on each thermal transfer unit by sandwiching the continuous raw fabric together with the ink ribbon between the thermal head and the platen (see, for example, Patent Documents 1 and 2).

  In conventional multicolor thermal transfer printers, a feed roller for running an original fabric such as a film is arranged downstream of each thermal transfer unit, and each feed roller is rotated by a stepping motor to feed the original fabric. Yes. According to this feeding method, there is a problem that speed fluctuation is likely to occur in the original fabric, and printing unevenness is likely to occur due to this, so that high-accuracy halftone printing is difficult. That is, in the conventional multicolor thermal transfer printer, since the original fabric is pulled on the downstream side of the thermal head in each thermal transfer unit, it is difficult to prevent the speed variation from occurring in the original fabric during printing. When the speed variation occurs, the image is distorted or color misregistration occurs. When such a printing defect occurs, it cannot be used as a transfer foil for painting an injection molded product.

It is a schematic front view which shows other embodiment of the multicolor thermal transfer printer which concerns on this invention.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

<Embodiment 1>
First, the transfer foil printed by this multicolor thermal transfer printer will be described.

  As shown in FIG. 1, the transfer foil 1 has a layer structure in which a release layer 3, a protective layer 4, an ink receiving layer 5, and an ink layer 6 are sequentially laminated on a base material layer 2. Among these, the layer constituting portion from the base material layer 2 to the ink receiving layer 5 is a continuous transfer foil original fabric 7 which is a kind of continuous original fabric, and is supplied to a later-described multicolor thermal transfer printer for printing.

  The base material layer 2 is formed of, for example, a PET (polyethylene terephthalate) film, paper, foil, or the like, and the protective layer 4 is formed of, for example, a UV curable acrylic resin. The release layer 3 and the protective layer 4 are also formed of known materials that need not be exemplified. The protective layer 4 and the ink receiving layer 5 are formed of a transparent material or a translucent material so that an image formed by the ink layer 6 can be seen through.

  The ink layer 6 is formed of a known thermoplastic resin ink. The ink layer 6 is formed by printing thermoplastic inks of various colors such as yellow, red, and indigo on the ink receiving layer 5 of the continuous transfer foil original fabric 7, thereby transferring the desired image on the transfer foil. 1 is made.

  As shown in FIG. 2, the transfer foil 1 is used for decorating the surface of the injection molded product 8 with a desired image.

  That is, the transfer foil 1 is attached to the mold so that the base material layer 2 is in contact with the cavity surface of an injection mold (not shown), and then the molten synthetic resin is injected into the mold. Then, simultaneously with the injection molding, the transfer foil 1 sticks to the surface of the injection resin 9 from the ink layer 6 side. After the injection molded product 8 is taken out from the mold, the substrate layer 2 and the like of the transfer foil 1 are removed, so that an image copied from the transfer foil 1 is exposed on the surface of the injection molded product 8. Thereby, the injection molded product 8 on which a fine and beautiful image is displayed is completed. Since the surface of the ink layer 6 is covered and protected by the protective layer 4, the surface of the injection molded product 8 is decorated with a beautiful image over a long period of time.

  Next, a multicolor thermal transfer printer for printing the transfer foil 1 will be described.

  As shown in FIG. 3, in this multicolor thermal transfer printer, a plurality of thermal transfer units I, II, III, and IV, each printing an image of a predetermined color ink on a continuous transfer foil original fabric 7, are arranged in series. It is constituted by.

  When viewed in the flow direction of the continuous transfer foil original fabric 7 in the multicolor thermal transfer printer, a feed roll 7a for feeding the unprinted continuous transfer foil original fabric 7 is installed on the upstream side, and an already printed web is provided on the downstream side. A take-up roll 7b for winding the continuous transfer foil original fabric 7 is provided. The rotating shafts of the vector inverter motors 24 and 25 are connected to the winding cores of the feeding roll 7a and the winding roll 7b, respectively. The rotation of both rolls 7a and 7b is controlled by vector inverter motors 24 and 25 so that the continuous transfer foil original fabric 7 travels between the rolls 7a and 7b at a predetermined speed.

  The thermal transfer units I, II, III, and IV are indigo, red, yellow, white from the upstream side to the downstream side of the continuous transfer foil original fabric 7 between the feeding roll 7a and the winding roll 7b. Are arranged to print each color ink. Of course, the arrangement of the thermal transfer units I, II, III, and IV is not limited to the order of indigo, red, yellow, and white. Also, the unit is not limited to four units, but may be three units of three color printing or two units of two color printing, or additional units may be added from four units so that other color inks can be further printed. Also good.

  As shown in FIG. 4, the thermal transfer unit I for indigo ink is provided with guide rollers 10 and 11 for detouring the continuous transfer foil original fabric 7 running in the horizontal direction upward. Above these guide rollers 10 and 11, a platen 12 for running a detoured continuous transfer foil original fabric 7 is disposed. Above the platen 12, the thermal head 13 is disposed so as to face the platen 12. An indigo ink ribbon 14 is disposed between the platen 12 and the thermal head 13.

  The platen 12 is a roll whose surface is covered with rubber. The platen 12 is directly connected to the rotating shaft of a constant speed control type servo motor 22.

  As shown in FIG. 4, nip rollers 15 and 15 that respectively press the continuous transfer foil original fabric 7 passing between the platen 12 and the thermal head 13 against the platen 12 before and after the thermal head 13 are used as necessary. Provided. The continuous transfer foil original fabric 7 is pressed against the surface of the platen 12 by the nip rollers 15 and 15, thereby preventing slippage between the continuous transfer foil original fabric 7 and the platen 12. In addition, the influence of vibration and speed fluctuation that occurs when printing is performed in the front and rear units is reduced. As a result, the image is printed more finely and beautifully.

  As shown in FIG. 4, a far-infrared heater 16 is installed below the platen 12 as preheating means for preheating the platen 12. The far infrared heater 16 preheats the platen 12 to the temperature of the platen 12 after the multicolor thermal transfer printer is started up. Since the surface of the platen 12 is made of rubber, heat is stored by continuing printing, the diameter fluctuates, and the traveling speed of the continuous transfer foil raw fabric 7 changes accordingly. Such inconvenience can be eliminated by heating in advance.

  The thermal head 13 can be moved up and down by a head vertical movement mechanism (not shown). By the operation of the head vertical movement mechanism, the thermal head 13 rises above the platen 12 during a paper splicing operation of the continuous transfer foil original fabric 7 and descends when printing an image as shown in FIG. As shown, the ink ribbon 14 is pressed against the platen 12.

  The ink ribbon 14 in the thermal transfer unit I for indigo color ink is obtained by applying indigo color ink to the surface of a film such as a PET film. The feeding roll 14 a and the take-up roll 14 b are used to connect the platen 12 and the thermal head 13. It arrange | positions so that it may pinch | interpose from the upstream and downstream of the continuous transfer foil original fabric 7. The feed roll 14a and the take-up roll 14b of the ink ribbon 14 are controlled so that the ink ribbon 14 travels around the platen 12 at the same speed as the continuous transfer foil original fabric 7 during printing shown in FIG.

  When the platen 12 is rotated at a constant speed by the constant speed control servo motor 22, the continuous transfer foil original fabric 7 is moved between the platen 12 and the thermal head 13 at a constant speed equal to the peripheral speed of the platen 12 and the ink ribbon 14. While passing in an overlapping state, an image of indigo ink is thermally transferred onto the surface.

  The thermal transfer unit I for indigo color ink is configured as described above, but the thermal transfer units II, III, and IV for other color inks are also configured in the same manner. However, only the ink color of the ink ribbon 14 is different. Therefore, detailed description of the thermal transfer units II, III, and IV of other color inks is omitted.

  The constant speed controlled servo motors 22 that drive the platens 12 of the thermal transfer units I, II, III, and IV of the respective colors are controlled by the control unit 17 so that all of them move the continuous transfer foil original fabric 7 at the same constant speed. Controlled by. Specifically, the constant speed control type servo motor 22 for driving the platen 12 is provided in the same number of four as the number of printing colors, and the other three rotation speeds are based on the desired one rotation speed. It is controlled to have the same rotational speed. Thereby, the continuous transfer foil original fabric 7 is fed in one direction by the platen 12 of each color, and the image of each color is printed on the surface without causing color misregistration.

  As described above, the continuous transfer foil original fabric 7 is moved under the thermal head 13 in each unit I, II, III, IV at the same constant speed by the platen 12 of each color thermal transfer unit I, II, III, IV. If the printing is continued in this state, the tension of the continuous transfer foil original fabric 7 gradually changes, which causes color misregistration and misregistration. When the tension is too low, the continuous transfer foil original fabric 7 is loosened, causing meandering or a printing start position shift. When the tension is too high, the film slips between the driving rollers and is not normally conveyed.

  In order to prevent this, as shown in FIG. 3, for example, between the feeding roll 7a of the continuous transfer foil original fabric 7 and the leading thermal transfer unit I, or the trailing thermal transfer unit IV and the winding roll 7b. Are provided with a tension detector 18 and tension adjusting rollers 19a and 19b, respectively.

  For example, a servo motor 23 is connected to one of the tension adjusting rollers 19a and 19b. The deviation between the tension detected by the tension detector 18 and the appropriate tension is sent to the servo motor 23 via another control unit (not shown). When the controlled driving force of the servo motor 23 is transmitted to the tension adjusting roller 19b, the continuous transfer foil original fabric 7 is kept constant in tension while the plurality of thermal transfer units I, II, III, IV. The image without color misregistration is printed.

  The tension detector 18 is also provided for the vector inverter motors 24 and 25 for rotating the feeding roll 7a and the winding roll 7b of the continuous transfer foil original fabric 7, respectively. The deviation between the tension detected by the tension detector 18 and the appropriate tension is also sent to the vector inverter motors 24 and 25 via the other control unit (not shown). The controlled driving force of the vector inverter motors 24 and 25 is transmitted to the feeding roll 7a and the take-up roll 7b, respectively, so that the tension of the continuous transfer foil original fabric 7 is kept constant.

  In addition, a vertical register mark and a horizontal register mark are displayed in advance on the continuous transfer foil original fabric 7, and color registration is performed in the thermal transfer units I, II, III, and IV of the respective colors based on the mark. This prevents the occurrence of color misregistration. Alternatively, the vertical register mark and the horizontal register mark are printed in the first thermal transfer unit I, and the subsequent thermal transfer units II, III, and IV are printed in accordance with the first printed vertical register mark and horizontal register mark. Although not shown, optical sensors for reading various registration marks are arranged in the thermal transfer units I, II, III, and IV of the respective colors. Read signals from each optical sensor are sent to a control unit (not shown) for processing, and an image signal output from the thermal head is corrected based on a signal from the control unit, so that color registration is appropriately performed.

  Next, the operation of the multicolor thermal transfer printer will be described.

  At the start of printing, the take-up roll 7a and the feed roll 7b of the continuous transfer foil original fabric 7 are rotated by driving of the respective vector inverter motors 24, 25, and the continuous transfer foil original fabric 7 becomes the thermal transfer unit I of each color. , II, III, IV.

  In each color thermal transfer unit I, II, III, IV, the platen 12 is rotated at a constant speed by driving a constant speed control type servo motor 22 and the continuous transfer foil original fabric 7 is moved from the upstream side to the downstream side. And send. At that time, the thermal head 13 presses the ink ribbon 14 against the continuous transfer foil original fabric 7 on the platen 12 to transfer the corresponding color ink as an image to the continuous transfer foil original fabric 7.

  Since all the platens 12 in the thermal transfer units I, II, III, and IV of each color are rotated at the same constant speed by the control of the constant speed control type servo motor 22 by the control unit 17, the continuous transfer foil original fabric 7 has Each color image is overprinted without shifting.

  The thermal head 13 in each color thermal transfer unit I, II, III, IV is always in contact with the platen 12 during printing. The head goes down in a stationary state before the start of printing, and after a specified number of images are printed on the continuous transfer foil original fabric 7, the head is raised and separated from the platen 12.

  The continuous transfer foil original fabric 7 on which an image is formed by printing all the colors is wound as a continuous transfer foil 1 on a winding roll 7a.

  When the printing is continued, the tension of the continuous transfer foil original fabric 7 may gradually change. Therefore, the tension of the continuous transfer foil original fabric 7 is detected by the tension detector 18 during printing, and compared with the appropriate tension, a speed change signal for eliminating the deviation is sent to the vector inverter motor 24 via a control unit (not shown). , 25 and the servo motor 23.

  The controlled driving force of the vector inverter motors 24, 25 and the servo motor 23 is transmitted to the tension adjusting roller 19b, the feeding roll 7a, and the take-up roll 7b, so that the tension of the continuous transfer foil original fabric 7 is constant. Passing through the plurality of thermal transfer units I, II, III, and IV while being maintained, a fine and beautiful image without color misregistration is printed.

  The continuous transfer foil original fabric 7 wound up as the take-up roll 7b is attached to the injection molding machine in a roll form and used as the transfer foil 1.

<Embodiment 2>
As shown in FIG. 5, in the second embodiment, a pair of feed rollers 20a and 20b for running the continuous transfer foil original fabric 7 are provided at predetermined locations in the multicolor thermal transfer printer.

  One feed roller 20a is a roller whose surface is covered with rubber, and the other feed roller 20b is a roller whose surface is covered with metal. The roller 20b covered with rubber is driven by a servo motor 21, for example.

  The feed rollers 20a and 20b are preferably installed on the running path of the continuous transfer foil original fabric 7 at the center of the four thermal transfer units I, II, III and IV.

  The servo motors 22 directly connected to the platens 12 of all the thermal transfer units I, II, III, and IV are driven based on the rotational speeds of the feed rollers 20a and 20b driven by the servo motor 21. , II, III, and IV are controlled to rotate at the same constant speed.

  Thus, the continuous transfer foil original fabric 7 is wound around the winding roll 7b after the image is printed without causing color shift.
