| 摘要 | A vibrating bowl is adapted to feed captive members, for example washers, along a tube having an outlet end disposed lower than the inlet end. The outlet end of the tube has a sleeve with lips preventing the captive members from exiting from the outlet end of the tube except when one end of a mechanical part, such as a bolt blank, the other end of which mechanical part slides down an inclined slideway, picks-up the top most captive member by sliding between said lips. A guide embracing said sleeve and lips and inclined relative to said slideway receives each top most captive member in turn and serves to move such member progressively towards said other end of said mechanical part as the latter continues to slide down said slideway. | ||||||
| 权利要求 | 1. Apparatus for automatically fitting captive members on mechanical parts comprising: a. means for forming a vertical pile of said captive members and for presenting them one by one and for forming a pick-up station situated at the top of the vertical pile; b. an inclined slideway passing over said pick-up station and one end of each mechanical part being engaged in said slideway so that as said parts slide theredown the other end of each mechanical part in turn passes said pick-up station and engages and picks-up the top most captive member of the pile thereof, and c. guide rack means embracing said pick-up station and inclined with respect to said slideway for causing each captive member upon becoming engaged on the other end of a corresponding mechanical part to be moved along said guide rack means and to be progressively moved towards said one end of the corresponding mechanical part as the part continues moving down said slideway. 2. Apparatus according to claim 1, in which said means for forming a vertical pile and a pick-up station comprises a vibratable bowl containing said captive members, a tube having one end disposed in relation to said bowl so that, due to the vibration of same, said captive members rise up in The bowl and are fed into and along said tube, the other end of said tube being disposed to rise to said pick-up station and to end at a level lower than said one end thereof, and a sleeve with lip means mounted on said other end of said tube for temporarily preventing exit therefrom of the captive members but permitting each top most captive member to be engaged and removed by said other end of a said mechanical part. 3. Apparatus according to claim 2, further comprising means for regulating the height of said bowl and said one end of said tube relative to said other end of said tube so as to regulate the rate of delivery of said captive members. 4. Apparatus according to claim 2, in which said tube is flexible. 5. Apparatus according to claim 1, in which said pick-up station comprises a sleeve with lip means mounted at one end of the vertical pile of captive members rising to said pick-up station. 6. Apparatus according to claim 1, in which means are provided for adjusting the angle of inclination and the position of said guide rack means in relation to said pick-up station. 7. Apparatus according to claim 1, in which said captive members are washers and said mechanical parts are bolt blanks. |
