Abstract: A modular manipulation arm formed from successive elements, each of which can pivot relative to the preceding one about a pivot axis coinciding with the axis of the element in question, and can pivot relative to the following one about a pivot axis which meets the axis of the element in question obliquely. These pivotings are obtained by means of rotary jacks which cause a drive-shaft portion to rotate relative to the corresponding element and which immobilize it in the selected position. The jacks are each associated with a distributor, itself preferably controlled by a low-power electric motor. The connection between successive elements preferably comprises a cardan joint linking the elements and oblique bearing surfaces at the end of the drive-shaft portions.

Abstract: This invention relates to a device for transferring objects from a gripping station to a depositing station, and is particularly applicable to the loading or unloading of panes of glass. The device includes at least one arm mounted perpendicularly to a shaft which drives it in rotation, with the arm being adapted to slide perpendicularly relative to the shaft. Gripping devices such as suction cups are mounted at each end of the arm, and a motor and indexer are provided for automatically controlling the rotation of the shaft, the sliding and locking of the arm, and the maneuvering of the gripping devices.
