Power grippers with stroke

With tight-closing jaws, FIPA power grippers with stroke and high gripping force grip flat sprues and flaps from injection moulding parts. For demoulding, the feed stroke allows for the grippers to be moved precisely towards the workpiece. The separate back stroke simplifies the parts depositing. The power grippers are single-acting and self-centering.


NEW

Series 840 - power grippers with stroke, clamping diameter 30 mm

Detects sprues larger 1 mm
  • Grippers with high gripping force and narrow closing gap for flat sprues
  • Feed stroke (cylinder 1) moves gripper towards the mold for part removal
  • Back stroke (cylinder 2) fully retracts gripper to enable undisturbed part release, e.g. on a conveyor belt
  • Grippers are self-centering
  • Suitable for heavy-duty applications due to closed, coaxial cylinder guiding
  • Part control via large area sensor activation, regardless of sprue position (GR04.140B, GR04.140B/NPN)
  • Detection of stroke via optional cylinder sensors
  • Easy exchange of jaws without snap-rings
