Description

The present invention relates to a suitable transformer box cosmetic film joining jig used for decoration of the transformer box that is installed on the ground with the cable underground.

In recent years, in order to improve the landscape, prevent disasters (prevent collapse of utility poles), secure road space, etc., electric wires have been undergrounded to eliminate utility poles for power transmission. On the other hand, even if the electric wire is underground, the transformer needs to be installed on the ground. Therefore, for example, a transformer that stores the transformer and other equipment at predetermined intervals on the sidewalk of a trunk road. A box is installed. In many cases, the surface of the transformer box is provided with a sticking prevention surface provided with a large number of small convex portions on one surface. The sticking prevention surface is provided so that the sticking paper such as leaflets, posters, and other various advertising papers cannot be stuck (or easily peeled off) by providing the large number of convex portions. There is.

However, on the other hand, it has not been possible to prevent mischief in which various graffiti is performed on the surface of the transformer box including the sticking prevention surface by spraying or brushing. In particular, since the sticking prevention surface has an uneven shape, it is more difficult to remove the graffiti than the flat portion, and countermeasures have been urgently needed. As a method of preventing the above-mentioned graffiti, etc., by reapplying a transparent clear paint on the normal coating on the surface of the transformer box, the surface is smoothed, thereby making it easier to remove the graffiti paint. Alternatively, a method of making the sticker more difficult to stick is also considered. However, even if this method is used, the effect of preventing graffiti and pasting itself is limited.

Therefore, as a more effective method for preventing the graffiti and the like, for example, as shown in Patent Document 1, a method of attaching a decorative film to a sticking prevention surface of a transformer box has been considered. That is, it is a method of sticking decorative films having various designs so as to correspond to the uneven surface of the sticking prevention surface of the transformer box and adhere to the surface. If the decorative film is directly attached to the surface of the transformer box to decorate it in this way, psychological suppression works on the act of trying to mischief such as graffiti, and the mischief etc. can be effectively prevented. it can.

As described above, the above-mentioned decorative film can effectively prevent mischief such as graffiti, and therefore its widespread use is progressing. Therefore, the decorative film has been required to further improve the aesthetic appearance.

Further, it has not been easy in the past to attach the decorative film to the surface of the transformer box having an uneven surface in close contact. That is, conventionally, a spatula-like squeegee was used to attach the decorative film to the uneven surface, but when attaching the decorative film to the uneven surface, it is necessary to use a thinner decorative film than before. Not only that, the squeegee could not evenly press the uneven surface. That is, in the squeegee, only the convex portion is strongly pressed, and the decorative film does not adhere between the convex portion and the concave portion around it (or adheres when pasted). Even if it is, there is a possibility that a part (which will be peeled off over time) will occur. Therefore, instead of the squeegee, there has been a demand for a construction jig capable of uniformly pressing and crimping a thin decorative film on an uneven surface.

FIG. 1 is a schematic perspective view showing an installation example of a transformer box 1 with makeup to which a transformer box decorative film (hereinafter, simply referred to as “decorative film”) 30 according to an embodiment of the present invention is attached. As shown in the figure, the transformer box 1 with makeup is installed on the sidewalk 11 (ground) on both sides of the road 10 at predetermined intervals. In the dressed transformer box 1, a transformer and other equipment that are connected in the middle of an electric wire buried underground (underground) of the sidewalk 11 and transform the voltage of the transmitted electric power are housed. The transformer box 1 with makeup is configured by applying desired makeup (the design surface 31 and the edge portion 33 described below) to the surface of the transformer box 1A.

FIG. 2 is a perspective view showing one transformer box 1 with makeup. As shown in the figure, the transformer box 1 with makeup has a box shape, and the areas of both side surfaces (the surface 13 facing the roadway 10 side and the surface 15 facing the sidewalk 11 side) along the traveling direction of the sidewalk 11 are It is formed in a large shape. The surface 15 facing the sidewalk has a pair of opening / closing doors 16a and 16b so that the double doors can be opened to the left and right.

Then, the decorative film 30 according to the present embodiment to which the makeup has been applied is closely attached to the surface 15 of the transformer box 1 with makeup, whereby the surface 15 is decorated. That is, the decorative film 30 decorates the tasteless and dry transformer box 1A composed of a single color of black or brown, which can contribute to the improvement of the cityscape. There is a gap S1 portion between the two opening / closing doors 16a and 16b constituting the surface 15, and the decorative film 30 is also two sheets in the gap S1 portion (first film portion 30-1 and second film portion 30-2). ) Is divided. Here, in reality, a large number of convex portions 17 are formed at equal intervals on substantially the entire surface of the surface 15 of the transformer box 1 with makeup, as shown in an enlarged manner in FIG. 4, and the large number of convex portions 17 are formed. The entire portion (substantially the entire surface 15) is used as the sticking prevention surface 19.

FIG. 3 is an explanatory diagram of a manufacturing method of the transformer box 1 with makeup. As shown in the figure, a decorative film 30 is prepared to form the transformer box 1 with makeup. The decorative film 30 is a film having a multilayer structure as described below, and is made of a thermoplastic material. The entire surface of the decorative film 30 is a decorative surface, and has a design surface 31 having various designs (designs, patterns, etc.) and an edge portion 33 having a predetermined width surrounding the periphery of the design surface 31. .. The design surface 31 may be any desired free design such as various desired patterns, patterns, characters, colors, and advertisement designs. On the other hand, the edge portion 33 is formed along the outer peripheral edge of the decorative film 30, and in this example, the color is the same as (or similar to) the color of the transformer box 1 around the decorative film 30. ) Is the color.

FIG. 5 is an enlarged schematic cross-sectional view showing the structure of the decorative film 30. As shown in the figure, the decorative film 30 includes a base film 43, a decorative printing layer 49, and a protective film 51, and is formed on the lower surface of the base film 43 before being attached. The release paper 41 is attached with the application tape 57 laminated on the upper surface of the protective film 51.

The base film 43 is formed by forming an adhesive layer 45 on the entire lower surface of the base film main body 47. The pressure-sensitive adhesive layer 45 is made of an acrylic pressure-sensitive permanent adhesive type white adhesive material having sufficient adhesive strength to attach the decorative film 30 to the surface 15 of the decorative transformer box 1. In this example, the base film body 47 is made of a flexible thermoplastic opaque white acrylic film. The base film main body 47 has a high base hiding property by making it opaque white. The upper surface (the surface on the opposite side to which the adhesive layer 45 is provided) is formed as a finished surface capable of producing high-quality graphics by a corresponding printer.

The decorative printing layer 49 is formed by printing a solvent by an inkjet method using, for example, an inkjet printer. As described above, in this embodiment, since the base film main body 47 is an opaque white film, when printing is performed on the base film body 47, high image quality and clear printing can be performed.

The protective film 51 is configured by forming an adhesive layer 53 on the entire lower surface of the protective film main body 55. The pressure-sensitive adhesive layer 53 is made of an acrylic pressure-sensitive permanent adhesive type transparent adhesive material having sufficient adhesive strength to attach the protective film main body 55 to the decorative printing layer 49. In this example, the protective film body 55 is made of a flexible thermoplastic transparent acrylic film. The protective film main body 55 has long-term outdoor durability, and by covering the decorative printing layer 49, the decorative printing layer 49 is protected from ultraviolet rays and the like, and the physical surface of the decorative film 30 is physically formed. It improves the physical strength, durability and weather resistance, and prevents the decorative printing layer 49 from falling off. The upper surface (the surface on the opposite side to which the adhesive layer 53 is provided) has a matte finish. The application tape 57 is made of a transparent olefin film. The release paper 41 is made of paper whose both sides are coated with polyethylene.

The decorative film 30 forms a decorative print layer 49 of a desired design on the upper surface of the base film 43 to which the release paper 41 is attached by an inkjet printer, and then applies the application on the upper surface of the decorative print layer 49. It is manufactured by laminating a protective film 51 to which a tape 57 is attached and sticking and integrating the adhesive layer 53 thereof. Since the decorative film 30 uses a white film as the base film 43 and forms the decorative printing layer 49 on the white film, the decorative printing layer 49 stands out and the decorativeness can be improved. Further, since the protective film 51 made of a transparent film is laminated on the decorative printing layer 49, the decorative printing layer 49 is clearly raised and its decorativeness is further improved.

Here, as another embodiment of the decorative film 30, there are also various materials described below. That is, in the above embodiment, a flexible and opaque white acrylic film is used as the base film main body 47 of the decorative film 30, and an acrylic pressure-sensitive permanent adhesive type white acrylic film is used as the pressure-sensitive adhesive layer 45. An adhesive material is used, while a flexible transparent acrylic film is used as the protective film main body 55 of the protective film 51, and an acrylic pressure-sensitive permanent adhesive type transparent adhesive material is used as the pressure-sensitive adhesive layer 53. Although used, for example, a flexible thermoplastic opaque white polyvinyl chloride film was used as the base film main body 47 of the decorative film 30, and an acrylic film was used as the pressure-sensitive adhesive layer 45. A pressure-sensitive re-peelable type gray adhesive material is used, while a flexible thermoplastic transparent polyvinyl chloride film is used as the protective film main body 55 of the protective film 51, and as the pressure-sensitive adhesive layer 53. , Acrylic pressure-sensitive adhesive type transparent adhesive material may be used.

Further, a urethane film may be used as the base film main body 47, a urethane film may be used as the protective film main body 55, an olefin film may be used as the base film main body 47, and an olefin film may be used as the protective film main body 55. A polyvinyl chloride film may be used as the base film main body 47, a fluororesin film may be used as the protective film main body 55, a urethane resin film may be used as the base film main body 47, and a polyvinyl chloride film may be used as the protective film main body 55. .. Furthermore, any one of an olefin film, an acrylic film, a polyvinyl chloride film, a urethane film and a fluorine film is used as the base film main body 47, and an olefin film, an acrylic film and a polyvinyl chloride are used as the protective film main body 55. Any one of a film, a urethane film, and a fluorine film may be used.

FIG. 6 is a diagram showing a transformer box decorative film attaching jig (hereinafter, simply referred to as “attaching jig”) 100 used when attaching the decorative film 30 to the surface 15 of the transformer box 1 (a). ) Is a front view, FIG. 6 (b) is a right side view, FIG. 6 (c) is a plan view, and FIG. 6 (d) is a bottom view. As shown in the figure, the sticking jig 100 includes a substantially cylindrical roller 110 having elasticity and a jig main body portion 150 that rotatably holds the roller 110. Further, the jig main body 150 is arranged at a position facing the pair of arm portions 151 that pivotally support the roller 110 on the left and right side surfaces and the outer peripheral surface (decorative film pressing surface) 133 of the roller 110. It is configured to have a grip portion 161 for integrally fixing the pair of arm portions 151.

The roller 110 has a substantially cylindrical shape, and is configured by attaching an elastic body 131 around a shaft support member (not shown) installed at the center of rotation thereof. Although not shown, the shaft support member is a mandrel made of a substantially cylindrical hard material (for example, metal or synthetic resin) installed in the center thereof, and a substantially cylindrical hard mandrel rotatably installed on the outer circumference of the mandrel. It is configured to include a rotating body made of a material (for example, metal, synthetic resin, etc.). Mounting holes made of female threads are formed at both ends of the mandrel. The elastic body 131 has a cylindrical shape and is made of an elastic body made of rubber, sponge, or the like. Then, the rotating body is inserted into the central hole of the elastic body 131 to rotate integrally. The outer peripheral surface of the elastic body 131 is a decorative film pressing surface 133. As shown in FIG. 6B, the decorative film pressing surface 133 is formed linearly in the width direction.

Each of the pair of arm portions 151 of the jig main body portion 150 has a flat plate shape, and is arranged so as to face parallel to the left and right side surfaces of the roller 110 with a predetermined gap. At the lower part of each arm portion 151, a mounting hole (not shown) for inserting a screw portion of a mounting member 155 made of a male screw is provided. Then, the screw portion of the mounting member 155 is inserted into the mounting hole from the outer surface side of the arm portion 151, and further screwed and fixed to the female screw provided on the end surface of the mandrel of the roller 110. As a result, the roller 110 (the elastic body 131 and the portion of the rotating body) is rotatably supported with respect to both arm portions 151 (and the mandrel of the roller 110).

The grip portion 161 of the jig main body portion 150 has a flat plate shape, and is formed in a shape curved in an arc shape with a radius of curvature larger than the radius of curvature of the outer peripheral surface (decorative film pressing surface) 133 of the roller 110. .. The jig main body 130 has a substantially oval shape (oval shape, substantially rectangular shape) when viewed from above, and is front and rear in a direction along the rotation direction of the outer peripheral surface (decorative film pressing surface) 133 of the roller 110. It has a long shape that extends to. Further, the outer edges of both of the extended tip portions of the grip portion 161 are formed in an arc shape, and a finger protection elastic portion 163 that wraps the outer edge portions is provided along the outer edge portions. The finger protection elastic portion 163 is made of an elastic material such as a rubber material.

A procedure for attaching the decorative film 30 to the surface 15 of the transformer box 1 will be described using the attachment jig 100 configured as described above. First, while peeling off the release paper 41 of the decorative film 30 shown in FIG. 5, the adhesive layer 45 is attached to the surface 15 of the transformer box 1. At this time, since a large number of convex portions 17 are formed on substantially the entire surface of the surface 15 as described above, the pressure-sensitive adhesive layer 45 is attached to the tip portion of each convex portion 17 (temporary adhesion). State). Next, while peeling off the application tape 57 shown in FIG. 5, as shown in FIG. 7, hot air Ha is applied from the exposed protective film 51 by a heating means 170 such as a dryer to soften the decorative film 30. At the same time, the decorative film pressing surface 133 of the roller 110 of the sticking jig 100 is pressed against the surface of the softened decorative film 30, and is evenly pressed against the surface 15 to roll. As a result, the entire portion of the decorative film 30 pressed by the roller 110 is adhered by the adhesive layer 45 while being deformed so as to be in close contact with the surface 15. Since the decorative film pressing surface 133 of the roller 110 has elasticity, when it is pressed against the surface 15, it is deformed according to the uneven shape of the surface 15 and adheres to the surface 15. Therefore, the decorative film 30 can be easily and surely deformed according to the uneven shape of the surface 15 and adhered to the surface 15. The sticking work is completed by performing the close contact work with the sticking jig 100 over the entire decorative film 30.

By the way, when the decorative film 30 is attached by the attachment jig 100, the hand that grips the grip portion 161 of the attachment jig 100 is shown by a dotted line in FIG. That is, the second joints of the index finger and the middle finger are bent, and the elastic portion 163 for protecting one finger of the grip portion 161 is pressed by the portion from the second joint to the fingertip side, and at the same time, the abdominal portion of the fingertip of the thumb is pressed. The side surface of the grip portion 161 or the outer surface of the arm portion 151 is pressed, the side surface of the grip portion 161 on the opposite side or the outer surface of the arm portion 151 on the opposite side is pressed with the ring finger and the little finger, and the abdomen of the palm is further pressed by the grip portion 161. Press against the top surface of. In this way, the sticking jig 100 has a shape that allows the jig main body 150 to be pressed from multiple directions by hand, so that the sticking jig 100 can be reliably held by hand and can be gripped by the entire palm. The portion 161 can be pressed from above, and the force for pressing the roller 110 against the decorative film 30 can be stably and greatly maintained. Further, since the elastic portion 163 for protecting the finger is formed on the tip side portion of the grip portion 161 where the index finger and the middle finger touch, the finger does not hurt even if the grip portion 161 is gripped with a strong force, and the jig main body is more firmly. The portion 150 can be gripped and fixed.

Then, the portion of the decorative film 30 that adheres to the surface 15 in close contact with the surface 15 and faces the gap S1 shown in FIG. 2 is cut at the central portion of the gap S1 by a cutter or the like, and the decorative film 30 is cut. Is separated into a first film portion 30-1 and a second film portion 30-2. At this time, the cut side portion of the decorative film 30 located in the gap S1 is folded back and adhered to the side surfaces of the opposing opening / closing doors 16a and 16b in the gap S1. In this way, the cut side of the decorative film 30 enters the gap S1 and becomes invisible (difficult to see) from the outside, and it is more unrecognizable that the film 30 is attached, which is preferable.

By the way, as described above, the decorative film pressing surface 133 of the roller 110 of the sticking jig 100 is formed linearly in the width direction as shown in FIG. 6B. As a result, the pressing force on the surface 15 for the entire width of the roller 110 becomes substantially uniform. As a result, the decorative film 30 for the entire width of the pressed roller 110 can be reliably adhered to the surface 15 only by rolling the roller 110 on the decorative film 30 while pressing the roller 110. Further, the decorative film pressing surface 133 may be formed in an arc shape in which the central portion is recessed in the width direction, as in the roller 110 of the sticking jig 100 shown in FIG. This is because there is no elastic body on the outer side of both end portions as compared with the central portion, and therefore the elastic force tends to be weakened when the surface 15 is pressed. Therefore, by increasing the thickness of both end portions, the elastic force tends to be weakened. This is to increase the elastic force of the minute, thereby further making the elastic force of the entire width direction uniform. On the other hand, like the roller 110 of the sticking jig 100 shown in FIG. 10, the decorative film pressing surface 133 can be formed in an arc shape in which the central portion protrudes in the width direction. In this case, the pressing force when the surface 15 is pressed is concentrated in the central portion, so that the entire pressing surface cannot be pressed uniformly, and when the surface 15 is pressed, the sticking jig 100 moves left and right (arrow A). There is a risk of blurring in the direction).
