〔考案の目的〕
（産業上の利用分野）
この考案は、注射針のバリ取り機における針先
カバー装置に関する。[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a needle tip cover device in a syringe needle deburring machine.
（従来の技術）
従来、注射針の針先部には機械により連続研磨
切削が行われており、この作業により第２図に示
すようにアゴ部分ＡにバリＢが生じる。そしてこ
のバリ取りには、小さなビーズを高圧のエアーで
バリの発生箇所に吹きつけて取る、所謂ブレスト
処理して行つている。(Prior Art) Conventionally, the needle tip of an injection needle has been continuously polished and cut by a machine, and this operation produces a burr B on the jaw portion A as shown in FIG. This burr removal is carried out by blowing small beads with high-pressure air onto the burr areas, a so-called breast process.
しかし、このバリ取り装置は針先の研削装置に
比べて遥かにに処理能力が優れているため、径や
長さの異なる種々の針もバリ取りする汎用性を持
たせる必要があつた。 However, since this deburring device has far superior processing power compared to a needle point grinding device, it was necessary to have the versatility to deburr a variety of needles with different diameters and lengths.
そこで従来のバリ取り装置は、ブレスト処理に
よりバリ取りをする場合には、折角尖らせた針先
を覆つてアゴ部分に細かいビーズを高圧にて噴射
して行う必要があり、この覆うための従来の装置
は、針の種類に応じ、その都度針先の長さに応じ
たプロテクターを取り替えて、しかも手作業で覆
つており、その作業は極めて非能率的であつた。
また、自動的に行うものとしては基台に列設した
針群に、上方よりラバーを素材とした覆いが針の
長さに応じてその距離だけ自動的に垂下し、針の
先端部をこのラバーが突き立てて覆い、ブラスト
処理していた。 Therefore, when deburring with conventional deburring equipment by breast processing, it is necessary to cover the sharpened needle tip and inject fine beads at high pressure into the jaw area. In this device, the protector was replaced each time according to the length of the needle tip depending on the type of needle, and the protector was covered manually, which was extremely inefficient.
In addition, a cover made of rubber material is automatically hung from above over a group of needles arranged in a row on a base by a distance corresponding to the length of the needle, and the tips of the needles are covered with this cover. It was covered with rubber and had been blasted.
しかし、この装置も長短の針に備え、予め最大
の長さの針から最小の長さの針の針先にビーズが
当たるよう常に無駄な幅にわたつてビースを噴射
させてブラスト処理しており、ビーズも多量に必
要とし、また出力の大きな噴射の動力源を必要と
しており、経済的でなかつた。 However, this device is also prepared for long and short needles, and is blasted in advance by spraying beads over an unnecessary width so that the beads hit the tips of the needles from the longest needle to the smallest length. However, it required a large amount of beads and a power source for injection with a large output, making it uneconomical.

そこでこの考案は上記の欠点を除去し、作業能
率に優れ、しかも効率のよい注射針のバリ取り機
における針先カバー装置を提供するものである。(Problems to be Solved by the Invention) Therefore, the present invention eliminates the above-mentioned drawbacks and provides a needle tip cover device for a hypodermic needle deburring machine that has excellent work efficiency and is highly efficient.
