One or more workpieces to be docked are stopped, separated and buffered on the workpiece support baffle defined in the conveying system or directly on the workpiece. Electronically controlled stop and stop separator with self-adjusting hydraulic damper, hard anodized aluminum housing, hardened steel stop. Used for the buffer separation of the workpiece holder with a load of 30 kg to 1000 kg, one-way action function, controlled by the one-way stroke control magnet, through the 9 mm descending stroke of the rotary joint, the upper position can be identified by the inductive sensor to identify whether the stop is Play a buffer role. The buffer type electric stop separator is used in all installation systems in various industries. To ensure efficient "stop-travel" movement in the production line-the stop function is realized by electromagnets, completely without pneumatic devices. Easy to install, compared with pneumatic system, work efficiency is improved several times. Reduce operating costs.
