| 摘要 |
<p>The present invention relates to a lifting suction nipple for a transport system designed to move work-pieces and comprises suction areas which are provided with a double-action cylinder (1) fitted with a suction cap (4) and a control unit (2) with a pneumatic distributing valve (14) as well as a low-pressure generator (16). The cavity (6) of the working cylinder is directly connected to the suction cap (4) and switching of the distributing valve (14) is automatically achieved when the suction nipple (4) reaches the work-piece. This produces an impact pressure, causing switching of the valve, after which a depression extending to the suction nipple (4) is produced in the first working area (6) which was previously pressurized.</p> |
