Positioning in stores and mechanical handling systems
Pepperl+Fuchs' PHA vision sensor for precise positioning enables fast and easy rack positioning. The vision sensor has an integrated camera and illumination. For positioning, the PHA sensor detects holes in racks and determines their position deviation from the current sensor location along the x and y axes. Four digital outputs, +X, -X, +Y, -Y are used to instruct the system which directions to travel to center the camera precisely over the hole. Once centered, the bin can be pulled without damage to the rack structure. An RS232 interface enables an optimized approach path towards the target position.
