<p>PURPOSE:To perform reliable discrimination of orientation of a part, by a method wherein, in a device for discriminating the orientation of a part such as a vibraion hopper, the features of a part are detected and stored in advance, compared with those of a passing part, and the its orientation is discriminated, based on a difference therebetween. CONSTITUTION:When a part 23 passes through a single observe/reverse discriminator 26, the observe or the reverse of the part are discriminated, and in turn- over, it is retained on a V rotor 27 by means of a shutter 28 to be turned over. Thereafter, the front and the rear are discriminated by a front/rear discriminator 29, and when it is in the state of front side back, the front or the rear is reversed by an H rotor 30. In which case, the front/rear discriminator 29 reads and stores the features of the part 23 with the aid of a reflection type photolectric sensor, and compares those of a part, passing therethrough, with the stored data each time a part passes through the sensor 29. This finds a difference between the data in relation to the part 23 to discriminate its orientation, resulting in the possibility to reliably discriminate the orientation.</p> |
