Abstract (en)
[origin: FR2747381A1] The present invention which discloses a device (1) for the transfer of a load (60) from a carrier onto a machine-tool supporting table and vice versa, is simple, inexpensive, very compact and of moderate weight. The transfer device consists of at least one handling arm (2) hinged and connected to the carrier and to the said load. The handling arm (2) is split into a front member (4) and a rear member (3) connected by a hinge. The closing and opening movement of the arm (2) is controlled by a jack (11) provided on the rear member (3) and its shaft is secured to a chain (12) intermeshing with two toothed wheels (14, 15) provided on the respective hinges (5, 6). The toothed wheels (14, 15) being stationary, the front (4) and rear (3) members of the arm rotate synchronously and in a ratio of 2 in relation to the jack (11), while the free end (7) of the arm follows a substantially rectilinear path parallel to the load transfer plane. The invention is useful in machine-tools, presses and any load transfer equipment.
