SENSITIZED VACUUM GRIP Russian patent published in 2006 - IPC B25J15/06 

FIELD: machine engineering, possibly searching and gripping flat articles.

SUBSTANCE: grip includes working suction devices whose cavity is communicated through pneumatic distributor with vacuum duct of ejector connected with pressure source by means of pneumatic valve and pressure regulator. Said cavity is also communicated through pneumatic distributor and additional pressure regulator with pressure source. Housing and working suction device together with receiving tube arranged in cavity of said device along its axis form annular pneumatic pickup for indicating part position. Additional suction device is mounted in non-fixed end of receiving tube. Outer surface of additional suction device form annular nozzle together with inner surface of working suction device. Duct of receiving tube is communicated with atmosphere and simultaneously trough pneumatic distributor it is connected with recess for opening contacts of part presence pickup. Recess for closing contacts of part presence pickup is communicated with vacuum duct. Duct of receiving tube through pneumatic distributor and additional pneumatic valve is communicated with vacuum duct.

EFFECT: enlarged manufacturing possibilities, improved operational reliability of grip.
