BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener chain decorating device for applying beautiful decorations with excellent surface strength to fastener elements of a slide fastener chain.

0002

[Prior Art] Conventionally, the fastener elements of a slide fastener chain made of a pair of fastener tapes each having a large number of plastic fastener elements planted at regular intervals on the edges are combined in an interlocking state. In step 1, an undercoat layer is first applied to the fastener element of the fastener chain by spraying using masking to improve adhesion to the vapor-deposited metal, and is dried and completely cured. Next, the fastener chain is placed in a vapor deposition tank, the undercoat layer of the fastener element is masked, metal vapor deposition is performed, and the fastener chain with the glossy design is taken out. Next, an overcoat layer for protecting the metal deposition on the fastener element is applied again by a spray method using masking, and is completely cured by drying to finish. The second method is to continuously feed out a long fastener chain and print on the fastener elements continuously by silk screen printing or offset printing to apply colored designs by printing.

0003

[Problems to be Solved by the Invention] However, in the first method, the painting process and the metal vapor deposition process must be performed using completely separate equipment, so the zipper chain is cut into strips. It is necessary to perform badge processing. For this reason, each process must be carried out intermittently by carrying around the zipper chain that is in the process of being painted. In addition, in each process, it was necessary to mask only the fastener elements, which was extremely complicated and time-consuming, and the mass productivity was low. Moreover,
The undercoat layer and overcoat layer are applied by spraying, but since the curable resin swims or flows out on the fastener element, it is difficult to obtain a uniform film thickness. The next process cannot be performed smoothly. Furthermore, if the curable resin leaks into the joint or the fastener tape, the slider may not move smoothly or the tape may be eroded. Furthermore, the spray method using masking has the problem that precise patterning cannot be achieved. Also, the second
It is impossible to obtain a pattern that combines metallic luster with vapor deposition. In addition, it was only possible to paint with poor surface durability. The present invention solves the above-mentioned problems, and provides a fastener chain decoration method that allows arbitrary designs to be formed only on the fastener elements of a fastener chain, thereby making it possible to easily manufacture a decorated fastener chain with excellent surface resistance. The purpose is to provide equipment.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 schematically shows the painting device of the present invention, in which an undercoat layer 4 is applied to the surface of the engaged fastener elements 3 while transporting the fastener chain 1, as shown in FIG. A decorative layer 5 and an overcoat layer 6 are successively formed thereon to manufacture the decorative fastener chain 1 shown in FIG. 3. As shown in Fig. 3, the fastener chain 1 to be painted is a colorless or colored fastener tape 2 made of woven or knitted fabric such as cloth.
A pair of fastener tapes 2 in which fastener elements 3 made of synthetic resin such as polyacetal, nylon, ABS, or polyester are planted at regular intervals on the edge of the tape are interlocked. The fastener chain 1 is fed out from, for example, a feed roll 7 wound into a roll, and an undercoat layer 4 made of a curable resin is formed on the surface of the fastener element 3. The curable resin is preferably a resin that can be formed into a highly resistant film and has good adhesion to the fastener element 3. There are various types of resins, but thermosetting resins, ultraviolet curable resins, electron beam curable resins, etc. are particularly suitable. Thermosetting resins include acrylic resins and vinyl resins. Examples of the ultraviolet curable resin include those composed of a prepolymer having a reactive double bond or a reactive epoxy group, a reactive diluent, a photoinitiator, an ultraviolet absorber, and an antioxidant. It is preferable to use a material containing such a curable resin as a main component and made into an ink or a paste using a solvent or the like. The coating device for forming the undercoat layer 4 uses a dispenser device 10 that can continuously form a precise coating film, and forms the coating film pattern, thickness, etc. continuously and with high precision so that the pattern and thickness of the coating film can be finely adjusted. , the dispenser device 10 fills the inside of the nozzle 11 with ink or paste made into an ink or paste using a solvent mainly composed of a curable resin, and the air pressure applied to the ink and the application time are finely controlled by the controller 12. Some are configured to finely adjust the discharge amount by adjusting the viscosity, and others are configured to finely adjust the speed by squeezing a hollow tube made of fluororesin into which low-viscosity ink or paste is sequentially fed. Further, the diameter of the needle 13 attached to the tip of the nozzle, the width of the brush-like Teflon needle, etc. are appropriately selected and used. Then, the undercoat layer 4 is sent to the next semi-curing device 20.
to a semi-hardened state. The semi-cured state is a state where the undercoat layer 4 is dry to the touch and not sticky to the touch, and the surface of the undercoat layer 4 remains active. To perform semi-curing, curing conditions differ depending on the type of curable resin that constitutes the undercoat layer 4. For example, if the undercoat layer 4 is made of an ultraviolet curable resin, an ultraviolet irradiation device is used as the semi-curing device 20. While the fastener chain 1 is continuously passed through this, ultraviolet rays or electron beams are irradiated while adjusting the irradiation conditions such as wavelength and intensity as appropriate, so that crosslinking of the resin is interrupted midway. In the case of thermosetting resin, a heating device such as a drying oven is used as the semi-curing device 20, and the zipper chain 1 is heated inside the semi-curing device 20.
While continuously passing through the solvent, the heating temperature is appropriately adjusted to volatilize the solvent.

[0006] Next, a decorative layer 5 is formed by a transfer method on the undercoat layer 4, which is sent to a transfer device 30 and brought into a semi-cured state. The transfer sheet 31 to which the decoration is applied is a base sheet that is peeled off after the transfer, and the decoration layer 5 that adheres to the fastener element 3 without being peeled off after the transfer.
The decorative layer 5 is formed by laminating a release layer, a pattern layer, an adhesive layer, etc. in this order from the base sheet side. As the base sheet, a film made of synthetic resin such as polyethylene terephthalate or polypropylene is used. The surface of the base sheet may be subjected to a release treatment. The release layer is a layer that is peeled off from the base sheet after transfer. The release layer is usually formed by gravure printing, and thermoplastic resins such as acrylic resins and vinyl resins can be used. The pattern layer may be a colored pattern, a glossy pattern, or the like, or may be a layer in which these are arbitrarily combined. The colored pattern is formed by a conventional printing method using a colored ink made of conventional pigments or dyes, binders, additives, etc. It is preferable to use a colored ink that has excellent adhesion to the release layer and excellent weather resistance. The pattern layer may be a single layer or may have a multilayer structure with multiple colors. Furthermore, the glossy pattern is formed from a thin film of metal such as aluminum, nickel, chromium, or tin formed by vacuum deposition, sputtering, ion plating, or the like. If necessary, anchor layers are formed on the upper and lower layers of the metal thin film. The adhesive layer adheres the above-mentioned transfer layer onto the fastener element 3. As the adhesive layer, a heat-sensitive or pressure-sensitive resin suitable for the surface material of the undercoat layer 4 is appropriately used. This transfer sheet 31
is continuously fed into the roll transfer device 30, superimposed on the fastener element 3 so that the adhesive layer is in contact with it, and is brought into close contact by heating and pressing from the base sheet side with a pad roll 32 made of silicone resin, and then the base sheet is peeled off. do. The portion that does not overlap the fastener element 3 is peeled off together with the base sheet, and the portion that overlaps the fastener element 3 is peeled off at the interface between the base sheet and the release layer and remains on the fastener element 3, leaving the decorative layer 5 under It is configured to be formed on the coat layer 4. Then, the above-mentioned painted layer 5 is sent to a second coating device.
An overcoat layer 6 made of a curable resin is formed thereon. The overcoat layer 6 is formed using the same curable resin as the undercoat layer 4, and regardless of the type of curable resin of the undercoat layer 4, the overcoat layer 6 may be a thermosetting resin or an ultraviolet curable resin. Resins can be used as appropriate. The overcoat layer 6 is formed by the dispenser device 40 in the same manner as the undercoat layer 4. Finally, the undercoat layer 4 and overcoat layer 6 are sent to a complete curing device 50 and completely cured, resulting in a finished product of the illustrated fastener chain 1 as shown in FIGS. 3 and 4, which is then wound into a roll. It is wound onto a roll 8. A fully cured state means that in the undercoat layer 4, the decorative layer 5 is strongly fixed due to the surface activity remaining in the process of semi-curing the undercoat layer 4, and it has excellent water resistance and solvent resistance. It is in a state of On the other hand, in the overcoat layer 6, the surface has sufficient weather resistance, abrasion resistance, washing resistance, fastness, etc.
That is, when the slider is attached to the fastener element 3 and used as a slide fastener, it has sufficient strength against friction with the slider and against erosion by water and solvent during washing. For complete curing, curing conditions differ depending on the type of curable resin that constitutes the undercoat layer 4 and overcoat layer 6. For example, if the overcoat layer 6 is made of an ultraviolet curable resin, an ultraviolet irradiation device is used as the complete curing device 50, and the irradiation conditions such as wavelength and intensity are adjusted as appropriate while the zipper chain 1 is continuously passed through the ultraviolet irradiation device. Then, the resin is irradiated with ultraviolet rays or electron beams with appropriate adjustment to complete crosslinking of the resin and completely cure it. In the case of thermosetting resin, a heating device such as a drying oven is used as the complete curing device 50, and the heating temperature is appropriately adjusted while the zipper chain 1 is continuously passed through the heating device to completely volatilize the solvent. Let it harden completely.

FIG. 2 shows another embodiment of the present invention. Normally, in order to completely cure a thermosetting resin,
This takes a long time, so this is done efficiently. The difference from the embodiment shown in FIG. 1 is that the overcoat layer 6 is brought into a semi-cured state in a semi-curing device 60 to eliminate tack, and then wound onto a winding roll 8 in a roll shape. The structure is such that the undercoat layer 4 and the overcoat layer 6 are allowed to cure and are finally completely cured. In this way, the fastener chain 1 can be wound up into a roll and placed in the curing device in a small space, which is efficient. Furthermore, since the semi-curing of the overcoat layer 6 and the semi-curing of the undercoat layer 4 are the same process, as shown in FIG.
It is also possible to semi-cure the overcoat layer 6 by feeding it into the semi-curing device 20 again as shown in FIG. With this configuration, there is no need to install a semi-curing device for the overcoat layer 6. Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented in various other embodiments. For example, the same decoration can be applied even if the fastener chain 1 is fed out not from a continuous take-up roll but by continuously feeding a long strip-shaped fastener chain 1. In addition, when forming the undercoat layer 4 and overcoat layer 6,
A rotary roll pad device may also be used. This is a format very similar to normal offset printing, in which a soft pad roll made of silicone rubber or the like is rotated to print a pattern received from a plate such as a metal intaglio plate, or a pattern that the pad itself has as a convex part, over a long length. This is a device that prints continuously and accurately on the curved surface of shakumono. Even with such an apparatus, it is possible to form a thin film with high density, and it is possible to form the undercoat layer 4 or overcoat layer 6 with high accuracy without waste. Furthermore, dust removal and dust collection may be performed immediately before forming the undercoat layer 4. Further, dust removal and dust collection may be performed immediately before forming the overcoat layer 6.

[0008]

According to the structure of the present invention, an undercoat layer is continuously formed on the surface of the fastener element while the fastener chain is being transferred, and a decorated layer is continuously formed thereon by a transfer method. Since the overcoat layer can be formed continuously, there is no need to take the zipper chain off the production line every time the process changes, improving the productivity of the painted zipper chain.
Mass production becomes possible. Further, according to the configuration of the present invention, since the painted layer is formed on the long zipper chain by the transfer device using the transfer material, various designs such as colored designs by printing and glossy designs by vapor deposition can be created. It is possible to carry out any combination of decorations, and the patterns are protected by an overcoat layer, so that a decorated zipper chain with excellent durability such as abrasion resistance and washing resistance can be obtained.
