OPTICAL DEVICE AND METHOD TO CHECK INCLINATION OF CONTAINER

摘要

Device for control of inclination of container (34) has light source (50) that is placed lower than container (34) and serves for light supply to bottom of container (62) at that as container is held in initial position and is rotated with respect to axis (A). Light-sensitive indicator (54) placed lower than container (34) obtains part of light from source (50) reflected from bottom of container (62). Processor for data processing (56) is connected to light-sensitive indicator (54) for determination of separation of bottom of container (62) from plane normal to axis (A) as joint function of parameters of reflected light and position of container. Container (34) is best variant is held in initial position and rotates with respect to axis by means of drive roller (24) that holds container (34) in front of additional rollers (26, 28) placed in axial position in such way that one can determine middle axis of rotation as function of geometry of container (34) and distance between additional rollers (26, 28).
