Abstract
The component sucking and holding machine concentrically comprises a first sucking pipe having a wider-area-sucking-opening at its end tip and a second sucking pipe inserted in the first sucking pipe, having a narrower-area-sucking opening at its end tip; the machine can easily suck and hold a component having various sizes by changing the relative position between the first and second sucking pipes.
Claims15
A component sucking and holding machine comprising:
- a first sucking pipe having a first sucking opening at one end thereof for sucking and holding a component wich has a suction surface area larger than the area of said first opening;
- a second sucking pipe disposed coaxially within said first pipe and having a second sucking opening at one end thereof for sucking and holding a component which has a suction surface area larger than the area of said second opening, the area of said first opening being larger than that of said second opening;
- first means for moving said first pipe axially relative to said second pipe between a first position where said one ends are at least substantially coplanar and a second position where said one end of said second pipe projects out of said first opening;
- and
- vacuum pump means for selective sucking of the air in said first sucking pipe and the air in said second sucking pipe.

- a second sucking pipe disposed coaxially within said first pipe and having a second sucking opening at one end thereof for sucking and holding a component which has a suction surface area larger than the area of said second opening, the area of said first opening being larger than that of said second opening;
- first means for moving said first pipe axially relative to said second pipe between a first position where said one ends are at least substantially coplanar and a second position where said one end of said second pipe projects out of said first opening;
- vacuum pump means connected to said second pipe;
- and
- valve means connecting the interior of said second pipe with that of said first pipe, said valve means being open when said one ends are at least substantially coplanar for sucking both said first and second pipes and closed when said one end of said second pipe projects out of said first opening for sucking only said second pipe.

- second means for moving said first pipe axially relative to said second pipe between a first position where said one ends are at least substantially coplanar an a second position where said one end of said second pipe projects out of said first opening;
- and
- vacuum pump means connected to at least said second pipe for selective sucking of the air in both said pipes or in only said second pipe.
