Method for aligning rectangular cargo part into e.g. rectangular pallet, involves detecting projected longitudinal dimension of rectangular object, and rotating object until detected longitudinal dimension possesses predetermined value

摘要

The method involves arranging a light curtain parallel to a transport plane (8), where the light curtain intersects a conveying direction (7). A longitudinal dimension of a rectangular object (10) is projected transverse to the conveying direction. The projected longitudinal dimension of the object is detected. The object is requirement-wise rotated until the detected projected longitudinal dimension possesses a predetermined value, where the predetermined value is a fixed value such as length, width or diagonal of the object or a relative value. An independent claim is also included for a device for aligning a non-circular or polygonal object transported in a conveying direction.
