A feeding device for feeding small parts to be identified and picked up and a part handling apparatus and sorting apparatus including the feeding device. The feeding device includes a picking platform, a dispenser arranged to dispense the parts to the picking platform, and a return member. The feeding device also includes a decelerator connected to the dispenser to reduce the speed of the part to be fed to the dispenser.

Feeding device for small parts

The invention relates to a method and an arrangement for measuring the geometry of grooves in an elongated element, which grooves () extend as continuous grooves over the whole length of the elongated element (), circling around the element, in which method the surface of the elongated element is scanned by of a camera (). In order to achieve simple non-contact measurement, the elongated element () is arranged to travel at the vertex through an annular biconical minor or through a biconical bevelled mirror () comprising several plane mirrors, and through a plane mirror structure () arranged at an oblique angle relative to the direction of travel of the elongated element (). An annular laser beam is directed to the plane mirror structure in such a way that the plane mirror structure () reflects the beam onto the surface of the elongated element () through the outer surface () of the biconical mirror or bevelled cone mirror. The image of the surface profile of the elongated element () produced from the surface of the elongated element () by means of the inner surface () of the biconical mirror or bevelled cone mirror () is turned to one side by means of the plane mirror structure () to allow the study of the groove geometry.
