【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、オイルシールフィーダから受取ったオイルシ
ールを搬送移動してシール受部に位置決め供給するオイ
ルシール供給装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an oil seal supply device that conveys and moves an oil seal received from an oil seal feeder to position and supply the oil seal to a seal receiving portion.
一般に、オイルシールなどの環状弾性部品を自動的にシ

し、シール受部に載置した後押圧機構で押圧してオイル
シールをシール受部に取付けるようになっている。Generally, an oil seal supply device that automatically supplies an annular elastic part such as an oil seal to a seal receiving part has a holding mechanism for holding the outer peripheral part of the oil seal and a pressing mechanism for pressing the oil seal to attach it to the seal receiving part. And a mechanism for holding the oil seal by a holding mechanism, transporting the oil seal above the seal receiving portion, placing it on the seal receiving portion, and then pressing it by a pressing mechanism to attach the oil seal to the seal receiving portion. .
しかし、上記オイルシール供給装置では、保持機構と押
圧機構とが別個に設けられているので、装置が複雑化す
るとともに作業能率に問題があった。However, in the above oil seal supply device, since the holding mechanism and the pressing mechanism are separately provided, the device becomes complicated and there is a problem in work efficiency.

に取付けるように構成したものが記載されている。For this reason, for example, in Japanese Patent Publication No. 59-11415, a pressing frame and a holder member that can be fitted to an oil seal are slidably provided on a movable frame that is driven to move above the seal receiving portion, and the oil seal is provided. The movable frame is moved above the seal receiving portion in a state where the holder is fitted and held by the holder member, and the pressing head is moved forward relative to the holder member, so that the oil seal is pressed by the pressing head. And the oil seal is attached to the seal receiving portion.

ールが損傷したりするという問題がある。In the oil seal supply device described in the above publication, since the oil seal can be conveyed and attached to the seal receiving portion by a single device in a continuous operation, the device can be simplified and the work efficiency can be improved. Since the oil seal is conveyed while being fitted and held by the holder member at the lip portion, the oil seal may fall off during the conveyance unless the fitting pressure of the oil seal is set relatively high. However, if the fitting pressure of the oil seal is increased, when the oil seal is fitted and held on the holder member, the lip portion may be turned up or the oil seal may be damaged due to a slight misalignment of the axial center between the holder member and the oil seal. There is a problem.

内嵌してオイルシールを保持する。When the pressing head provided on the movable member is moved forward with respect to the seal receiving portion, the positioning member elastically supported by the pressing head via the elastic member moves forward through the elastic member and is held by the opening / closing arm. The oil seal is retained by being fitted inside the lip portion of the oil seal.
これと並行的に、開閉アームがカム部とバネとの共働に
より開作動され、また、位置決め部材がシール受部に同
心状に位置決めされる。At the same time, the opening / closing arm is opened by the cooperation of the cam portion and the spring, and the positioning member is positioned concentrically with the seal receiving portion.
次に、押圧ヘッドの押圧部が位置決め部材に対して相対
的に前進作動して、オイルシールを押圧し、位置決め部
材から離脱させてシール受部へ外嵌させる。Next, the pressing portion of the pressing head moves forward relative to the positioning member, presses the oil seal, separates it from the positioning member, and fits it on the seal receiving portion.
その後、押圧ヘッドが後退作動すると、位置決め部材も
後退し、開閉アームがカム部によりバネに抗して閉作動
される。After that, when the pressing head moves backward, the positioning member also moves backward, and the opening / closing arm is closed by the cam portion against the spring.
