Description

本考案は一種のクラッチ装置に係り、特に油と塵埃の進入を防止して内クラッチ盤と外クラッチ盤間のエリアの清潔を確保し、運転時に、油と塵埃の汚染によるミシン部品の損壊を防止し、これによりミシン全体の寿命を延長する、クラッチ装置に関する。   The present invention relates to a kind of clutch device, and in particular, prevents the entry of oil and dust to ensure the cleanness of the area between the inner clutch panel and the outer clutch panel, and damages the sewing machine parts due to contamination of oil and dust during operation. The present invention relates to a clutch device that prevents and thereby extends the life of the entire sewing machine.

現在業界で応用されているミシンは、布送り駆動装置のクラッチ機構が特許文献１に記載されているように、摩擦盤ａ、駆動装置ｂ、内クラッチ盤ｃ、外クラッチ盤ｄ及び連接棒機構ｅ等の部品で構成されており、それは図１に示されるようである。   The sewing machine currently applied in the industry has a friction disc a, a driving device b, an inner clutch disc c, an outer clutch disc d, and a connecting rod mechanism, as described in Patent Document 1 for the clutch mechanism of the cloth feed driving device. e and the like, as shown in FIG.

上述の構造により、揺動機構ｆが伝送する推移量を、分段式に該外クラッチ盤ｄ及び内クラッチ盤ｃを通して該摩擦盤ａに伝送し、該駆動装置ｂに間欠性の定方向回転を発生させ、該駆動装置ｂに針送りと布送りの作用を達成させる。   With the above-described structure, the transition amount transmitted by the swing mechanism f is transmitted to the friction disc a through the outer clutch disc d and the inner clutch disc c in a stepwise manner, and intermittently rotated in the unidirectional direction to the drive device b. And the drive device b achieves the functions of needle feeding and cloth feeding.

上述の構造は、該内クラッチ盤ｃに防塵リングｃ１が嵌設されており、それは該内クラッチ盤ｃと外クラッチ盤ｄの間に介装されて油及び塵埃を遮断するのに用いられるが、該内クラッチ盤ｃの外縁の幅は有限で、それに設置できる防塵リングｃ１も断面が小さ過ぎ、密封効果が不良となり、塵埃が該内クラッチ盤ｃと外クラッチ盤ｄの間の隙間より進入するのを有効に防止することができない。   In the above-described structure, the inner clutch disc c is fitted with a dust-proof ring c1, which is interposed between the inner clutch disc c and the outer clutch disc d and used to block oil and dust. The width of the outer edge of the inner clutch disc c is limited, and the dust-proof ring c1 that can be installed on the inner clutch disc c is too small in cross section, resulting in a poor sealing effect. Cannot be effectively prevented.

特にミシンを停止してオイルによるメンテナンス作業を行なう時、スプレーされた余分の油が該内クラッチ盤ｃと該外クラッチ盤ｄの間よりしみ込み、内クラッチ盤ｃと外クラッチ盤ｄの間のエリアを汚染し、運転時に、油と塵埃の汚染により部品が損壊し、これによりミシン全体の寿命が大幅に短縮され、修理コストの支出も増える。   Particularly when the sewing machine is stopped and maintenance work is performed with oil, the sprayed excess oil penetrates between the inner clutch disk c and the outer clutch disk d, and between the inner clutch disk c and the outer clutch disk d. Contaminated areas and contaminated parts during operation due to oil and dust contamination, which greatly shortens the overall life of the sewing machine and increases repair costs.
