ABSTRACT:
In an automatic sorting system for sorting objects conveyed on a conveyor, a camera is used for pattern recognition of the object being sorted. Due to the difference in sizes of the objects being sorted, the camera must be focused depending on the size of the object under consideration. Instead of moving the camera section itself, an optical path bending section can be included between the camera and the objects to be examined. The optical path bending section includes at least one pair of reflector mirrors disposed so that the reflecting surfaces thereof face each other at an angle of 90 degrees. In order to enable focusing for different sized objects, the optical path bending section can be moved in a direction parallel to the optical paths entering and exiting the optical path bending section.
