Operating principle of the retractable stop
This retractable stop is drived by a double-acting pneumatic cylinder. It is retracted by a 90 ° rotation of the finger. When it is engaged to stop the moving element, it is mechanically locked by a toggle joint action.
The retractable finger supports an impact force of 1280 N or less, it is generally necessary to provide damping at the point of contact (elastic or hydraulic depending on the application).
Detection by 2 inductive Ø8 detectors is optional.
Using of the retractable pneumatic stop
There are 3 common applications for this retractable stop:
• Create an intermediate position for a manipulator or a linear pneumatic gantry
• Create a conveyor stop
• Referencing a product on a workstation
For an intermediate position of the pneumatic manipulator, a hydraulic shock absorber must be placed opposite the stop screw. For conveyor stops, an elastic absorber may be sufficient.
