【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、歯ブラシ毛先加工技術に係り、毛先部分の
みをテーパ状および先丸に２段加工する方法およびその
装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush bristle processing technique, and more particularly to a method and a device for processing only a bristle part into a tapered shape and a rounded tip in two steps.
最近の歯ブラシのフィラメントはほとんどが合成樹脂
であるが、フィラメントはブラシ台に植毛された後に長
さを揃えるためにロータリーカッターで毛先ろ切断して
いる。ところが、そのままで切断面が鋭角状になってい
るので加工を施さないままで利用すれば、歯茎を傷つけ
るという衛生上の問題がある。Most of the filaments of recent toothbrushes are made of a synthetic resin, but the filaments are cut at the tip of a brush with a rotary cutter in order to make the length uniform after being planted on the brush stand. However, there is a hygiene problem that the gums are damaged if used without processing because the cut surface is sharp as it is.
そこでこれを解決するために、従来から鋭角状の切断
面を軽く回転やすりに押圧して研磨し、毛先を丸く加工
することによってこのような事故を防止していた。Therefore, in order to solve this problem, such an accident has been conventionally prevented by gently pressing a sharp cut surface with a rotating file to grind it, and rounding the bristle tip.
ところで、従来の製造工程による歯ブラシでは、第１

は２段加工にするとはできなかった。By the way, in the toothbrush by the conventional manufacturing process, the first
As shown in the figure, the filament has a columnar shape, and only the tip portion is rounded. However, rather than having such a shape, it is easier to taper the hair tips into a tapered shape as shown in FIG. be able to. Therefore, means for processing the bristle tip having such a shape is required, but it has not been possible to perform the two-step processing by the conventional processing method.
本発明はこれら従来の加工方法を改良したもので、毛

にするという機能を行う。In the present invention, a cutting step, a taper polishing step, and a tip polishing step are continuously performed. In the cutting step, the function of equalizing the length of the filament is performed. In the taper polishing step, the tip of the filament is tapered. In the tip polishing step, the tip of the hair is polished to form a shape that does not damage the gums.

ことがある。FIG. 3 shows an outline of the processing steps of the present invention. FIG. 3 shows the outline of the processing steps of the present invention. Fig. 3 (a)
The tips are not aligned like. Therefore, in order to align the tips, a hair cutting process is performed as shown in FIG. 3B. The tips are aligned by a rotary cutter 3 having a plurality of cutter blades on a rotating shaft. Next, since the tip of the cut hair tip has an acute angle, it is polished as shown in FIG. 3c to polish the tip, and is also tapered by the same device. To explain this processing technique, first, about 1/4 of the filament length is pressed against the file surface 5 of the rotating file 4 for a certain time in order to taper about 3 mm at the tip of the filament.
In this case, if the time is too long, the taper angle becomes deep, so it is necessary to set the time to an appropriate time. Subsequently, after processing into a tapered shape, the tip of the hair is once separated from the file surface 5, and further, the tip of the hair is lightly contacted at a distance slightly away from the file surface 5 in the tapering process. In this way, a two-step filament in which the tapered tip is further rounded can be manufactured. Here, brush base 1 and file 5
Is finely adjusted by a step motor or the like.
In addition, in order to make the processed product uniform and improve the yield, the process of FIG. 3B and the process of FIG. 3C may be performed twice each.

細部の歯垢まで除去することが可能となった。Since the present invention uses the above-described processing method and apparatus,
It is possible to perform two-stage processing of the filament tip with almost no change to the conventional device, and it is possible to avoid accidents such as damaging the gums as before, and to narrow the teeth by tapering. The bristle tip penetrated, and it was possible to remove even the fine plaque that could not be removed with a conventional toothbrush.
