Abstract

(Image Omitted) The apparatus includes a finger 1 (Fig. 1) which is reciprocable through a row of clamp rings 2 along their axial center line. The clamp rings 2 are asymmetrical and may be positioned in one of two orientations in the row. Each clamp ring has one face which is flat, the other being castellated, the raised portion of the castellated face being relieved and having a chamfer that returns to the base of the castellation. The free end 3 of the finger 1 has a recess 4 in its upper surface which is accurately dimensional to receive a ring 2 (Fig. 2). In the base of the recess but insulated therefrom are two pairs of sensor contacts 5,6 and 7,8 (Fig. 3). A ring 2 in position in the recess 4 connects either the contacts 5 and 6 (Fig. 2) or the contacts 7 and 8, if in the opposite orientation.

Unloading Rings for Robotic Handling

(Image Omitted)

The apparatus includes a finger 1 (Fig. 1) which is reciprocable through a row of clamp rings 2 along their axial center line. The clamp rings 2 are asymmetrical and may be positioned in one of two orientations in the row. Each clamp ring has one face which is flat, the other being castellated, the raised portion of the castellated face being relieved and having a chamfer that returns to the base of the castellation. The free end 3 of the finger 1 has a recess 4 in its upper surface which is accurately dimensional to receive a ring 2 (Fig. 2). In the base of the recess but insulated therefrom are two pairs of sensor contacts 5,6 and 7,8 (Fig.
3). A ring 2 in position in the recess 4 connects either the contacts 5 and 6 (Fig.
2) or the contacts 7 and 8, if in the opposite orientation. An endless 'O' ring section neoprene belt 9 is stretched around two pulleys at either end of the fork and driven by a motor through a reduction gearbox. All the rings 2 in a row are raised by insertion of the finger 1 through their central holes and raising of the finger. The belt 9 is driven by its motor to transport the rings along the finger 1. The end ring enters the recess 4 and connects either one of the pairs of contacts 5,6 or 7,8. The belt-driving motor is stopped, and the robot is informed as to the orientation of the ring in the recess 4. After removal of the ring by the robot (and re-orientation, if necessary), the moto...
