Description

  The present invention relates to a thermal marking head for transferring a foil stamping material to a transfer object.

  The foil stamping machine can transfer the foil to the transfer object by pressing a hot stamping head heated from above the foil to be the transfer object against the transfer object. By transferring such a foil, it is possible to draw arbitrary characters, symbols, figures, patterns or the like on the transfer object such as leather products, thereby enhancing the decorative property of the transfer object. As such a foil stamper, for example, a foil stamper described in Patent Documents 1 to 3 has been proposed.

  By the way, in order to draw more detailed figures and patterns on the transfer object, it is necessary to make the tip of the hot stamping head thinner. However, if the tip of the hot stamping head becomes thin, sufficient heat is transferred to the transfer object. It tends to be unable to transfer well. Moreover, in order to improve the transfer speed by the foil stamping machine and improve the productivity, it is necessary to shorten the time during which the thermal stamping head presses the transfer object as much as possible. However, if the time for pressing the object to be transferred is shortened, sufficient heat may not be transmitted to the transferred object, and transfer may not be performed properly.

  The present invention solves the above-described problems, and can draw more detailed figures and patterns on the transfer object, and also allows time for the thermal stamping head to press the transfer object. An object of the present invention is to provide a thermal marking head that can be made as short as possible to improve productivity. It is another object of the present invention to provide a foil stamping machine, a foil stamping method, and an article to be transferred obtained by using the hot stamping head.

  Patent Documents 1 to 3 do not describe a material constituting the thermal marking head, but generally use copper. The present invention has been completed by finding that the above-mentioned problems can be solved by using titanium as a material constituting the thermal marking head. That is, the present invention relates to a thermal marking head having a substantially cylindrical shaft portion and a protrusion provided on the bottom surface portion of the shaft portion, the bottom surface portion and the protrusion portion containing 20% by mass or more of titanium.

  It is preferable that the present invention further be a thermal marking head having a titanium alloy plating layer on the surface of the bottom surface and the protrusion.

  The present invention is preferably a thermal marking head in which the diameter of the protrusion is 2 mm or less.

  The present invention relates to a foil stamping machine having the above-mentioned hot stamping head.

  The present invention relates to a foil stamping method using a foil stamping machine having the above-mentioned hot stamping head.

  The present invention relates to an article to be transferred which has been transferred using a foil stamping machine having the above-mentioned thermal marking head.

  By using the thermal marking head of the present invention, it becomes possible to draw more detailed figures and patterns on the transferred object, and the time during which the thermal marking head presses the transferred object is made as short as possible. Productivity can be improved.

It is a figure which shows an example of the thermal marking head of this invention. It is a figure which shows an example of the thermal marking head of this invention. It is a figure which shows an example of the thermal marking head of this invention, a cylindrical member, and a member for a motion. It is a figure which shows an example of the foil stamping machine of this invention.

  Hereinafter, although embodiment of this invention is described, this invention is not limited to this.

  The thermal marking head of the present invention has a substantially cylindrical shaft portion and a protrusion provided on the bottom surface of the shaft portion. The substantially cylindrical shaft portion has a substantially columnar cavity therein, and the thermal marking head can be heated by inserting a heater.

  The thermal marking head of the present invention has a protrusion on the bottom surface of the shaft portion. With such a structure, heat is easily transmitted to the protrusions, and the thermal efficiency for pressing the foil is increased. For example, when the entire thermal marking head has a substantially conical shape without providing a protrusion, sufficient heat is not transmitted to the tip of the protrusion, which is a portion that presses the transferred material, and as a result, transfer cannot be performed successfully. .

  The shape of the thermal marking head of the present invention is not particularly limited, and examples thereof include a thermal marking head having the shape shown in FIGS. A thermal marking head 10 shown in FIG. 1A has a substantially cylindrical shaft portion 12 and a protrusion 11 provided on a bottom surface portion 13 of the shaft portion 12.

  The shape of the shaft portion of the thermal marking head is not particularly limited, but in addition to the substantially cylindrical shape like the shaft portion 12 of the thermal marking head 10 shown in FIG. 1A, the thermal marking head shown in FIG. As shown in FIG. 20, the shaft portion 22 having a large diameter and the shaft portion 25 having a small diameter may be combined.

  As shown in FIG. 2A, the shaft portion 12 of the thermal marking head 10 has a shaft hole 14 for inserting a heater. Similarly, the shaft portion 22 of the thermal marking head 20 has a shaft hole 24 as shown in FIG. 2 (b), and the shaft portion 32 of the thermal marking head 30 is as shown in FIG. 2 (c). In addition, a shaft hole 34 is provided.

  The shape of the protrusion of the thermal marking head is not particularly limited. For example, in addition to the substantially conical shape like the protrusion 11 of the thermal marking head 10 shown in FIG. 1A, the heat shown in FIG. A substantially conical shape having a short overall length such as the protrusion 21 of the marking head 20 or a needle shape such as the protrusion 31 of the thermal marking head 30 shown in FIG.

  In the thermal marking head of the present invention, the bottom surface portion of the shaft portion and the protrusion of the thermal marking head (hereinafter referred to as “the tip portion of the thermal marking head”) contain 20% by mass or more of titanium. Titanium contained in the tip of the thermal marking head is preferably 40% by mass or more, more preferably 60% by mass, and further preferably 80% by mass.

  Since titanium is a metal having a smaller heat capacity than other metals, it is possible to maintain the thermal marking head at a high temperature with less heat energy. Therefore, even if the tip portion is thin, it is possible to transfer sufficient heat to the transferred material. Therefore, a more detailed figure or pattern can be drawn on the transfer object. Even if the time during which the thermal marking head presses the transfer object is shortened, sufficient heat can be transmitted to the transfer object, so that the productivity of the transfer object can be improved by the transfer.

  The metal material other than titanium used for the tip of the thermal marking head is not particularly limited, and examples thereof include copper and iron.

  In the present invention, it is preferable to have a titanium alloy plating layer on the surface of the tip of the thermal marking head. The surface of the tip of the thermal stamping head has a titanium alloy plating layer, so that the durability of the tip of the thermal stamping head can be improved and the deterioration of the thermal stamping head due to long-term use can be suppressed. it can.

  In order to improve the durability of the tip portion of the thermal marking head, for example, as shown in FIG. 1B and FIG. 2B, titanium alloy plating is applied to the protruding portion 21, the shaft portion 22, and the bottom portion 23. As shown in FIGS. 1 (c) and 2 (c), a mode in which titanium alloy plating is applied to the protrusion 31 and the bottom surface 33 is conceivable.

  In the embodiment where the titanium alloy plating is performed, the durability of the protrusion of the thermal stamping head is improved. However, in the embodiment containing titanium, heat is transmitted to the protrusion of the thermal stamping head even if the titanium alloy plating is not performed. It has become easier. The thermal stamping head of the present invention can draw a more detailed figure or pattern on the transfer object in any of the above-described aspects, and the hot stamping head presses the transfer object. The time can be as short as possible to improve productivity.

  The metal other than titanium forming the titanium alloy is not particularly limited, and examples thereof include tin, manganese, aluminum, vanadium, and iron.

  In the thermal marking head of the present invention, the diameter of the protrusion is preferably 2 mm or less, more preferably 1 mm or less, further preferably 0.5 mm or less, and 0.2 mm or less. Is particularly preferable, and is particularly preferably 0.1 mm or less. When the diameter of the protrusion of the thermal marking head exceeds 2 mm, it tends to be difficult to draw a dense figure or pattern. Here, the diameter of the protruding portion refers to the diameter at the coupling portion of the bottom surface portion.

  In the thermal marking head of the present invention, it is preferable that the total length of the protrusion is 2 to 3 mm. If the total length of the protrusions of the hot stamping head exceeds 3 mm, the protrusions of the hot stamping head tend to break during foil pressing.

  In the thermal marking head of the present invention, the protrusion angle of the protrusion is preferably 30 ° or less, more preferably 20 ° or less, and further preferably 10 ° or less. When the angle of the protrusion of the protrusion exceeds 30 °, heat is not sufficiently transmitted to the foil, and proper foil pressing tends to be impossible.
