済む。According to the toothbrush flocking and decorating apparatus of the present invention as described above, the drive system of the intermittent conveyor of the flocking machine is used to perform the process of bonding the decorating member to the handle. There is no need to provide a special drive system. In addition, since the flocking machine is provided with a means for bonding the decorating member and ultrasonically welded to each other, the handle portion and the decorating member can each be manufactured by a general-purpose mold,
Unlike the conventional insert molding method, there is no need to use a special and complicated mold, and the mold manufacturing cost can be reduced. In addition, the handle portion is filled with a hard synthetic resin material and cooled and solidified. By completing the molding, the molding cycle can be shortened as compared with the insert molding method.On the other hand, in the molding of the decorative member, since the thermoplastic resin or the thermoplastic elastomer is solely molded, the hard synthetic resin is used. The cooling efficiency is better and the molding cycle is shorter than when insert molding is performed on the handle part molded by the method described above.

トの低減を図ることができる。As described above, according to the present invention, when manufacturing a toothbrush handle by bonding a decorative member made of a thermoplastic resin or a thermoplastic elastomer to a handle part made of a hard synthetic resin, The decorating member is molded separately from the handle portion using a thermoplastic resin or a thermoplastic elastomer, and is adhered to the handle portion by an ultrasonic welding machine using a drive system of a flocking machine. Also, the decorative member can be manufactured by a general-purpose mold, and there is no need to use a special and complicated mold as in the conventional insert molding method, and the mold manufacturing cost for handle molding can be reduced. Also, compared to the insert molding method, the molding cycle can be shortened, and the production efficiency can be improved, thereby reducing the manufacturing cost of the toothbrush. Can.

Also, after decorating the handle with heat transfer or hot stamping, the decorating member is adhered, so that the decorating member interferes with rollers or up-down type pressing work during thermal transfer or hot stamping. The decoration such as characters and patterns can be applied to the peripheral portion of the decorative member bonding portion without becoming undesired. Therefore, the toothbrush manufactured using the processing device of the present invention has excellent appearance and design.
