Description

  The present invention relates to a sleeve signboard excellent in design that can be attached to a pole such as a utility pole or pole.

A large number of sleeve signboards displaying predetermined information such as road guides, stores, products, etc. are attached to utility poles, poles, etc. standing from the road surface.
For example, in Patent Document 1, when attaching to the utility pole, the binding bands 2u and 2d are wound around the predetermined height of the utility pole 1, and the arms 3u and 3d are projected from the binding bands 2u and 2d in a horizontal direction in a cantilever state. Then, a mode is introduced in which the upper and lower frames 5u and 5d for connection reinforcement of the information display board 4 are fixed to the arms 3u and 3d with bolts and nuts 6. And as the information display board 4, the coated steel plate which showed the predetermined information is used, and the flat shape is maintained by reinforcing the right and left edge part with the side frames 5r and 5l for reinforcement (refer FIG. 1, 2). .

In Patent Document 2, the information display board 4 is fixed to the utility pole 1 by connecting the connecting portions of the upper and lower connection reinforcing upper and lower frames 5u and 5d to the sleeve signboard support arms 3u and 3d with bolts 6u and 6d. Has been introduced. Also in this document, a double-sided coated steel plate is used as the information display board 4, and the flat shape of the information display board 4 is maintained by arranging the reinforcing side frames 5r and 5l on the left and right edges (FIGS. 3, 4, and 4). 5). In addition, 7 in FIGS. 4, 5 and 6 is a rivet joint.
And in the above-mentioned sleeve signboard, the display of the predetermined information on the steel plate surface is often performed by a technique of printing on the coating film provided on the steel plate surface.

By the way, as a form to give a desired display pattern on an information display board made of a coated steel plate by a printing method, a form to be cut out to an information display board of a predetermined size and printed before attaching the reinforcing outer frame, and the reinforcing outer frame It is assumed that a desired pattern is printed after attaching. As a printing method, a screen printing method is usually used.
In the form of printing before attaching the reinforcing outer frame, screen printing is performed on a completely flat coated metal plate, and then the reinforcing outer frame is attached, so the printing work itself is easy, but the cost does not increase when the number is large. Will be expensive.

  In contrast, in the form of printing after attaching the reinforcing outer frame, a large number of sleeve signs with reinforcing outer frames of the same shape are formed, and then the necessary display pattern is printed only in the necessary amount. Therefore, the cost can be kept low. However, since the screen printing is performed after the reinforcing outer frame is attached, the printing surface is restricted. That is, the sleeve signboard to which the connection reinforcing upper and lower frames 5u, 5d and the reinforcing side frames 5r, 5l are attached has a cross-sectional shape as shown in FIGS. For this reason, in order to perform screen printing, the frame must be accommodated in the outer frame for reinforcement of the sleeve signboard. As a result, the printing surface becomes narrow and the entire surface of the sleeve signboard cannot be patterned.

Moreover, although it is a common problem in adopting the screen printing method, the front and back surfaces of the information display board cannot be printed simultaneously by screen printing. Further, since the screen printing method uses an organic solvent, the working environment is deteriorated.
The present invention has been devised to solve such problems, and a desired pattern on the entire front and back surfaces, including the outer frame surface for reinforcement, even in the case of a telephone pole signboard with a reinforcing outer frame attached thereto. It aims at providing the sleeve signboard for telephone poles with high design property attached | subjected to.

  In order to achieve the object, the utility pole sleeve signboard of the present invention has an information display board 4 provided with a resin coating on both sides, and the information display board 4 is attached to the utility pole fixing support arms 3u and 3d. An electric pole sleeve signboard having connection reinforcing upper and lower frames 5u and 5d attached to upper and lower ends of the information display board 4 for connection, wherein a resin coating film provided on the information display board 4 is provided. It consists of a resin coating film having good dyeing property, and a sublimation dye dyeing layer is formed in the thickness direction of the resin coating film in a predetermined pattern by transferring a sublimation dye to the resin coating film.

The information display plate 4 is preferably made of a double-side coated steel plate. Even if the information display board 4 is provided with reinforcing side frames 5r and 5l made of outer surface coated steel plates fixed to both front and back surfaces of each side edge of the information display board 4 with spaces provided respectively on the side edges thereof. Good. The coating film provided on the steel plates forming the reinforcing side frames 5r and 5l is made of a resin coating film having good dyeing property, and the sublimation dye dye is dyed in a predetermined pattern by transferring the sublimation dye to the resin coating film. It is preferable that the adhesion layer is formed in the thickness direction of the resin coating film.
Furthermore, the upper and lower frames 5u and 5d for connection reinforcement are formed of a coated steel plate, and the coating film of the coated steel plate is made of a resin coating film having good dyeing property. The sublimation dye is transferred to the resin coating film in a predetermined pattern. The sublimation dye dyeing layer may be formed in the thickness direction of the resin coating film.

In the telephone pole sleeve signboard of the present invention, a desired pattern is applied to the information display board and, if necessary, the coating film on the surface of the connection reinforcing upper and lower frames and the reinforcing side frame by transfer printing. Since the screen printing method that requires a printing frame is not used, a pattern can be added to the surface of the upper and lower frames for connection reinforcement and the side frames for reinforcement as needed. , The advertising effect can be greatly improved. In addition, by adopting the transfer printing method, a required pattern can be simultaneously applied to the front and back surfaces of the sleeve signboard.
Furthermore, since a desired number of patterns can be transferred and printed on the sleeve signboard after being formed into a predetermined size, a small lot product can be manufactured at low cost. Furthermore, the deterioration of the working environment can be suppressed by adopting the transfer printing method.

The present inventors are unified in terms of size, but the utility pole sleeve signboard with various patterns such as promotional text is excellent in durability and high advertising effect even in small lot products We investigated a method for efficiently creating a sleeve signboard.
As for the shape / structural durability measures of the sleeve signboard, the technology disclosed in Patent Documents 1 and 2 was studied.
As a result, the present inventors have found that it is effective to employ a transfer printing method that has already been proposed by the present inventors to penetrate a sublimable dye.
Details will be described below.

The shape and structure of the sleeve signboard may be those proposed in Patent Documents 1 and 2 as described above. Therefore, a method for forming a transfer printing pattern on a sleeve signboard having a structure proposed in Patent Document 2 will be described.
First, as the information display plate 4, a base steel plate surface such as a normal steel plate, a stainless steel plate, or a plated steel plate provided with a transparent or translucent resin coating is used. Although it is preferable to use a coated steel plate provided with resin coatings on both sides, two single-sided coated steel plates may be used. When the coating is performed, it is preferable to provide a white base coat or a primer layer as necessary between the base steel plate and the resin coating. The white base coat conceals the color tone of the base steel sheet, and the primer layer has an action of preventing corrosion of the base steel sheet by adding a rust preventive pigment or the like.

The resin coating formed on the base steel sheet must be a layer on which the sublimation dye dye layer is formed by thermal transfer of the sublimation dye, and the reflection of the printed pattern that appears in the sublimation dye dye layer. In order to secure a sufficient concentration, it is preferable to form the film with a thickness of 5 μm or more. Instead of the white base coat, a resin layer exhibiting another color tone including a clear resin can be formed, and either a single layer or a multilayer structure may be used. A protective coating may be provided on the transparent or translucent resin coating as necessary.
The type of the resin that forms the transparent or translucent resin coating film is not particularly limited as long as it is a resin that accepts the sublimation dye transferred from the transfer sheet and dyes it well.

  The upper and lower frames 5u and 5d for connection reinforcement are fitted into the upper and lower edges of the information display board 4 made of the base steel plate on which the resin coating film as described above is formed. Further, the reinforcing side frames 5r and 5l may be fitted into the side edges. In order to enhance the reinforcing effect, the reinforcing side frames 5r and 5l are preferably formed by bending a steel plate into a conical flask-shaped cross section as shown in FIG. When the bent side reinforcing frames 5r and 5l are fitted to both ends of the information display board 4, “the steel plate is fixed to both front and back surfaces of the side edge of the information display board 4 with a space provided. An arrangement of the “reinforcing side frame” is obtained. The side frame shape for reinforcement may be formed by bending both side ends of the coated steel plate into a triangular cross section. The one formed by bending the side end is also referred to as a reinforcing side frame.

The steel plate forming the reinforcing side frame is preferably made of a normal steel plate, a stainless steel plate, a plated steel plate, or the like, and has a precoat coating film capable of forming the same sublimation dye dye layer on the outer surface thereof. In addition, the steel plates forming the upper and lower frames for connection reinforcement are made of ordinary steel plates, stainless steel plates, plated steel plates, etc., and have a precoat coating film on the outer surface that can form the same sublimation dye dye layer as described above. preferable. The shape of the connection reinforcing upper and lower frames is not particularly limited.
After the reinforcing side frames 5r, 5l and the connecting reinforcing upper and lower frames 5u, 5d are fitted, the two are fixed with a driving rivet 7 or the like.

  When a rivet is driven, if there is a step due to rivet bonding on the transfer surface of the information processing board or a step due to the overlap of the coated steel plates, an untransferred printed part may occur at the step, which may reduce the print quality. is there. In order to suppress this deterioration in quality, the joint of the information display board is provided on the side part of the reinforcing frame that does not transfer as much as possible, and a step due to the overlap of the coated steel sheets is provided as close as possible to the end of the information processing board. It is preferable to apply. The idea of the rivet driving position contributes to the enlargement of the printing area and at the same time the added value of the signage by improving the printing quality.

Transfer printing is performed on the sleeve signboard manufactured by the above procedure.
When a transfer sheet preliminarily patterned with a sublimation dye is brought into contact with the transparent or translucent resin coating or protective coating on the information display board 4 and heated and pressurized, the sublimated dye penetrates into the resin coating. A pattern dyed in the thickness direction is formed by the sublimation dye dyeing layer.
As the transfer sheet, a sheet produced by gravure printing, offset printing, screen printing or the like is used. For small lot printing, it may be produced by electrographic method, electrostatic recording method, ink jet method, thermal transfer method and the like which do not require a plate making process by using computer graphics.
The sublimable dye refers to a dye that can be transferred by a phenomenon such as sublimation or volatilization when heated. For example, a disperse dye such as a quinophthalone derivative, an anthraquinone derivative, or an azo dye is preferably used. Sublimation dyes conventionally used in sublimation heat transfer, sublimation transfer printing and the like can be used without particular limitation.

Next, a mode in which transfer printing is performed by heating and pressing will be described.
As the apparatus, as shown in FIG. 7, a press machine having a base 11 and a pair of upper and lower upper flanges 15 and 16 between them is used. A heating element is provided on the upper and lower pair of upper and lower eyelets 15 and 16. The upper rod 15 is attached via a spring 14 to a mounting plate 13 that is horizontally attached to the lower end of a connecting rod 12 that is supported on the upper portion of the base 11 so as to be movable up and down. The spring 14 has a function of adjusting the strength of the applied pressure. An air cylinder 17 is attached above the base 11 as power for moving the upper rod 15 up and down to press the object to be transferred, so that the connecting rod 12 and the upper rod 15 connected thereto are moved up and down. It is configured.

Normally, since the upper collar 15 and the lower collar 16 are formed in a flat plate shape, the information on the sleeve signboard in which the reinforcing side frames 5r and 5l and the connecting reinforcing upper and lower frames 5u and 5d are fitted to have an irregular cross section. A uniform pressure cannot be applied to the display panel 4.
Therefore, when transferring and printing the sleeve signboard, a lower mold 18 whose cross section matches the cross-sectional shape of the transferred sleeve signboard is attached on the lower collar 16, and a cross section of the upper sleeve 15 has a cross section on the lower surface thereof. An upper die 19 matching the shape is attached. The material of the upper collar 15, the lower collar 16, the upper mold 19, and the lower mold 18 is preferably made of a lightweight aluminum alloy that is excellent in thermal conductivity and is movable.

  Further, porous elastic bodies 20 and 21 are arranged between the transferred object and the upper mold 19 and the lower mold 18 so that equal pressure is applied to both surfaces of the transferred object. As the porous elastic body, it is preferable to use silicon foam, urethane foam, heat-resistant felt or the like which has fine holes and is excellent in elasticity, breathability and heat resistance. By providing an elastic body, the elastic body is deformed during pressurization and heating to absorb the difference in thermal expansion between the mold and the transferred object, and pressurizing and heating the transferred object uniformly and gently. be able to. Furthermore, gas generated from the transfer paper can be quickly removed through the elastic body having air permeability. By these actions, the elastic body brings about an effect that a clear transfer pattern can be obtained without causing "deviation" or "bleeding" in the transferred pattern of the transfer object. In the transfer printing of the sleeve signboard, the three-dimensional shape product is subjected to thermal transfer. Therefore, it is preferable to use the elastic body cut so as to match the cross-sectional shape of the transferred sleeve signboard. The thickness is preferably about 5 mm to 10 mm.

The following form is preferable as the thermal transfer procedure.
The elastic body 21 is placed on the lower mold 18 of the lower eyelid 16 to which a lower mold whose cross section matches the cross-sectional shape of the transferred sleeve signboard is attached. On the elastic body 21, a transferred sleeve signboard T on which a transfer paper P with a desired printing pattern on both sides is attached is placed. The upper elastic body 20 is placed in such a form that the transfer paper is interposed on the sleeve signboard.
Thereafter, the air cylinder 17 disposed above the base 11 is operated to lower the upper rod 15 and press it toward the lower rod 16 side.

The heating element embedded in the upper collar 15 and the lower collar 16 is caused to generate heat, and the transferred sleeve signboard is heated via the elastic bodies 20 and 21. It is preferable that the temperature of the heating element is set so that the surface temperatures of the upper rod 15 and the lower rod 16 are 180 to 230 ° C.
When a predetermined pressure is applied and heated to a predetermined temperature, the pattern of the transfer paper is transferred and printed on the information display board 4 of the sleeve signboard, and the sublimation dye forming the pattern penetrates the coating layer, and the desired pattern A sublimation transfer pattern is formed on both surfaces of the information display board 4 of the sleeve signboard formed from the coated steel plate.

  At this time, in addition to the information display board 4 constituting the sleeve signboard, a steel sheet constituting the reinforcing side frames 5r and 5l is used in which a precoat coating film capable of forming a sublimation dye dye layer is formed on the outer surface. If the transfer paper is arranged so as to overlap the reinforcing side frame surface, a sleeve signboard in which a sublimation transfer pattern is also formed on the reinforcing side frame surface can be obtained. Further, if a sheet having the same precoat coating film is used as the steel plate constituting the connection reinforcing upper and lower frames 5u, 5d, and the transfer paper is disposed so as to overlap the upper and lower frame surfaces for connection reinforcement, the upper and lower frames for connection reinforcement are provided. A sleeve signboard in which a sublimation transfer pattern is also formed on the frame surface can be obtained.

As described above, by adopting a transfer printing technique using a sublimation dye, a desired pattern can be further provided on the entire surface of the information display board, if necessary, on the side frame surface for reinforcement or upper and lower frames for connection reinforcement. Since it can also be formed on the surface, it is possible to supply a billboard sign for a telephone pole with a large advertising effect at a low cost.
In addition, since the dye penetrates into the coating film resin and a desired pattern is formed, the pattern can be kept clear for a long time, and as a result, the durability of the sleeve signboard can be improved.
