Self Aligning Object Placement Apparatus

This is an apparatus for positioning objects onto a receiving member in a preselected translational and rotary orientation, without the requirement of either Precision object placement for pickup or close construction tolerances in the pickup assembly itself.

A freely moveable object pickup assembly 10 includes an upper cylinder 12 and a lower cylinder 14, one end of each cylinder having ground surfaces 13 and 16, respectively. The ground surfaces are abutted against each other. A spring 17 connected to each of the other ends of the cylinders 12 and 14 biases the cylinders so that their axes remain substantially parallel, although the axes may be laterally shifted with respect to each other. Object alignment collar 20 with chamfered inner surface 30 and outer surface 33 is slidably mounted at the lower end of cylinder 14.

Stop plate 26 is fixedly mounted on the bottom of lower cylinder 14 for attachment of spring 17 to member 14. Stop plate 26 has drilled holes 27 for engaging and retraining object 38, when cylinders 12 and 14 are evacuated by vacuum source 29 connected to cylinder 12 by vacuum line 28.

A reciprocating bar 11 moves the cylinders 12, 14 towards an object 38 placed anywhere within a pickup zone. Chamfered surface 30 on the inside of object alignment collar 20 causes this collar and cylinder 14 to laterally position themselves for engagement with the object 38. Cylinders 12 and 14 are then moved away from the...
