Pneumatic stopper with retractable finger by rotating 90° in the direction of movement of the pallet
Locking by toggle joint action
Options :
Detection of positions
3 possible contacts on the retractable finger:
. Hydraulic chock absorber
. Elastic absorber
. Stop screw
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 in the direction of movement of the pallet or the object to be stopped. When it is engaged to stop the moving element, it is mechanically locked by a toggle joint action which ensures high repeatability of this stop (<0.05 mm with mechanical stop).
The retractable finger supports an impact force of 1280 N max when it is engaged, depending on the speed and the mass of the object to be stopped, it is generally necessary to provide damping at the point of contact (elastic or hydraulic depending on the application).
The retractable finger is tapped as standard in M8x1 (other tapping on request, Ø12 max).
This tapping makes it possible to receive an adjustable mechanical stop to adjust the position of the stop, an elastic absorber or a hydraulic shock absorber
Detection by 2 inductive Ø8 detectors is optional.
A left version and a right version are available depending on the mounting direction.
Using of the retractable pneumatic stop
There are 3 common applications for this retractable stop:
• Create a conveyor stop, a stop pallet, a separating stop, a stopper cylinder
• Create an intermediate position for a manipulator or a linear pneumatic gantry
• Referencing a product on a workstation
