BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener chain continuous patterning device capable of continuously transferring an arbitrary pattern pattern to the surface of a fastener chain in a slide fastener.

[0002]

2. Description of the Related Art Conventionally, in order to apply a pattern to a surface of an articulator of a fastener chain by a transfer means, a fastener stringer and a heating roller having a silicone rubber on a peripheral surface thereof and a receiving roller in contact with the heating roller are provided. A thermal transfer film obtained by sequentially polymerizing a release layer, a protective layer, a vapor-deposited metal layer, and an adhesive layer on a plastic film is supplied, the fastener stringer is received along the curved surface of the roller, and the thermal transfer film is heated and pressed onto the articulator by a heating roller. There is known a device (see Japanese Patent Laid-Open No. 2-218303 and FIG. 8) in which the silicon rubber is elastically deformed to insert a heat transfer film between the articulators and to deposit the vapor-deposited metal layer on the surface of the articulators. There is.

[0003] Further, the fastener chain is transferred to a roll type transfer device in order to apply a pattern to the surface of the fastener chain of the fastener chain by a transfer means. First, the nozzle of the dispenser device is first mounted on the fastener chain of synthetic resin. A solvent of thermosetting resin is applied from a needle to form an undercoat layer, which is then sent to a semi-curing device such as a drying oven to process the undercoat layer in a semi-cured state, and then transferred to a transfer device. Release layer on the base sheet,
Send a transfer sheet with a pattern layer and adhesive layer laminated,
By applying heat and pressure from the base sheet side with a pad roll made of silicon resin, the design is transferred onto the fastener articulator to form a painting layer, and then a curable resin is applied onto this design layer with a dispenser device. To form an overcoat layer, and then completely cure the undercoat layer and the overcoat layer by a complete curing device to complete a fastener chain with a picture (Japanese Patent Laid-Open No. 4-36).
7605 and FIG. 9) are known.

The above-mentioned first known example is
It is a device that transfers a design to the surface of an articulator in a fastener stringer, not a device that transfers a design to the entire surface of a fastener chain. Therefore, it is necessary to expand the space between the articulators in order to transfer them sufficiently to the surface of the articulator.
Therefore, the fastener stringer is extended along the curved surface of the receiving roller to expand the space between the occlusal elements, and the heat transfer film is pressed against the upper surface of the occlusal element by the heating roller. Therefore, the contact between the heat transfer film and the heating roller is point contact, that is, partial heat contact cannot be performed with sufficient heat pressure contact, and there is a transfer effect if it is a fastener articulator, but as a device that transfers the pattern pattern to the entire fastener chain Inappropriate.

Further, the well-known second example is, like the first example, an apparatus for transferring a pattern onto the surface of an articulator in a fastener chain, not an apparatus for transferring a pattern onto the entire surface of a fastener chain. Therefore, the fastener chain is sent linearly to the pad roll and the receiving roller made of silicon resin, and the transfer sheet is fed onto the articulator and heated and pressed by the pad roll, so that the pattern is transferred to the articulator. Therefore, the transfer sheet and the articulator are in partial contact with each other, and the transfer effect can be obtained with the fastener articulator, but it is unsuitable as an apparatus for transferring a picture pattern on the entire surface of the fastener chain.

It is a device that can easily and reliably transfer the design pattern to the entire surface of the fastener chain including the fastener articulator, especially since the fastener chain and the transfer film are heat-treated in close contact with the outer peripheral surface of the heating roller for a certain period of time for a certain period. There is an advantage that the transfer is beautiful and smooth on the entire surface of the fastener chain.

The heating roller is a rotating body having a width corresponding to the fastener chain width, and a heat-resistant elastic material layer is arranged on the surface thereof.
Since the concave groove for accommodating the fastener articulator is provided in the center of the surface, there is an advantage that the fastener chain can be accommodated accurately and the fastener chain and the transfer film can be efficiently heated.

The transport unit for transporting the fastener chain has a first guide roller and a second guide roller having a width corresponding to the fastener chain width, which are arranged in contact with each other before and after the heating roller, and the transport roller is provided at a rear position. Since the pressure roller and the pressure roller are arranged in pressure contact with each other, the operations of the heating roller and the conveying roller are synchronized with each other, so that the fastener chain and the transfer film are accurately guided to the outer peripheral surface of the heating roller, and the heating process is accurately performed in a certain section. Further, since the fastener chain can be transported, since the transport roller and the heating roller operate in synchronization, there is an advantage that the fastener chain can be transported in a normal state without being damaged.

In the transfer section for transferring the transfer film, the supply rollers are arranged above and below the fastener chain in front of the first guide roller, and the winding rollers are arranged above and below the fastener chain behind the second guide roller. The transfer film can be accurately guided to the surface of the fastener chain, and after the heat treatment, the second
The transfer film is peeled from the fastener chain at the position of the guide roller, but since the peeling operation is performed in a state where there is residual heat, there is an advantage that the transfer can be finished beautifully.

The pressing portion for pressing the fastener chain and the transfer film against the heating roller is a drum-shaped driven roller formed of a heat-resistant elastic material having a width corresponding to the fastener chain width, and is moved forward and backward by the operation of the cylinder. Since they are contacted with each other, the entire fastener chain is pressed efficiently, and in particular, the driven roller is formed into a drum shape by making the inner ring portion and the outer ring portion different in diameter, and the elastic deformation amount is made different. There is an advantage that the heat treatment can be effectively performed by uniformly pressing.

Furthermore, since a plurality of driven rollers are provided, the driven rollers themselves are formed by springs so as to be elastically contactable with the heating roller, and a concave groove is provided around the center of the surface.
The effect of the present invention is extremely remarkable, such as the advantage that the fastener chain can be pressed against the heating roller without difficulty in a certain section and can be guided accurately.
