The Inspector P series also adds functions for giving position information of irregular shaped objects, known as blob detection. The sensor’s part positioning tool set reports the X, Y and rotation angle of the taught part over TCP/IP Ethernet communication or via 4 digital switching outputs. When working with known objects, the user can add in “grip regions” to verify that a part is unobstructed and can easily be picked by an automated picking system (robot). The “blob tool” allows users to work with objects that are less repeatable in shape, such as food picked from a belt. The user defines the criteria of the blob, including pixel intensity, area, number of blobs (min/max) and rotation angle. The P30 can then report the details of the blob to the user via TCP/IP. It is also possible to set a “pass region,” meaning that a digital I/O signal can be triggered when a blob is in the correct position.
