Abstract: A retractable antifriction bearing device (10a) that can be housed in a standardized groove of a loading bed. Each ball (30) is mounted directly in a housing (21a) of the profile (20a) by a guide and sealing ring (50) provided with a spherical cavity (53) that complements the ball (30) to hold the ball in position with respect to the housing (21a). A bearing guide (60a) is also mounted directly in the housing (21a) and is provided with a cup (61) guiding the ball (30) in rotation via a bed of small balls (62). This bearing guide (60a) is spring-loaded by spring elements (40a) so as to urge the ball (30) into the working position in which the ball bears the load (2).

Abstract: A winder in which the jaws of the mandrel expand automatically by the weight of the reel, without introducing external energy. The winder has a mandrel of horizontal axis (A) whose jaws are expandable by means of links hinged to the end of a sliding pull rod and connected to the frame by a hinged connecting rod. The winder includes a rocker connected to the frame by a fixed pivot axis (D) and to the mandrel by the physical embodiment of the axis of rotation (A), the two axes (D, A) are parallel. The rocker moves the mandrel vertically between a raised loading position and a lowered use position under the weight of a reel and it brings about, simultaneously, sliding of the pull rod, automatic expansion of the jaws, and automatic clamping of the reel.

Abstract: A device (30) for handling a load (C) such as a sheet iron coil comprises a holder (32) capable of carrying the load (C). The holder (32) is able to be rotated on a frame (31) between a first position, in which the axis of the load (C) is vertical, and a second position, in which the axis of the load (C) is horizontal. The frame (31) of the device (30) is coupled to a driving assembly (35) so as to be mobile in order to load and unload the load (C) on a reel (D). The holder (32) includes a mechanism for maintaining and positioning (36) the load (C), retaining the load (C) during a change of the position of the load, and depositing the load on and/or removing the load from the reel (D).

The winder has a mandrel of horizontal axis (A) whose jaws are expandable by means of links hinged to the end of a sliding pull rod and connected to the frame by a hinged connecting rod. The winder includes a rocker connected to the frame by a fixed pivot axis (D) and to the mandrel by the physical embodiment of the axis of rotation (A), the two axes (D, A) are parallel. The rocker moves the mandrel vertically between a raised loading position and a lowered use position under the weight of a reel and it brings about, simultaneously, sliding of the pull rod, automatic expansion of the jaws, and automatic clamping of the reel.

Abstract: The invention concerns a roller track device based on simple kinematics, enabling reduction of the number of parts and production costs of the assembly as well as its space requirement, and designed for being fitted on new handling apparatuses as well as for retrofitting. The invention also concerns a platform or fork handling apparatus equipped with such a device. The roller track device (10) comprises a substantially horizontal table (21) whereon are mounted ball sockets (23), with a rack (31) mounted on top provided with openings (32) arranged opposite the balls (23). The rack (31) is mobile relative to the table (21) between a high position wherein it conceals the balls (23). A handle (41) coupled to the rack (31) enable its displacement in horizontal translation (Th).

Abstract: The invention concerns a roller track device based on simple kinematics without energy input, enabling reduction of the number of parts, of production cost of the assembly and of its space requirement, easy maintenance, and designed for being fitted on new handling apparatuses as well as for retrofitting. The roller track device (100) comprises a rail (310) bearing the static load, a guard rail (210) housed in the rail (310) and wherein are mounted rolling members (230) bearing the moving load. The guard rail (210) is coupled to a pivoting lever (410) co-operating with a lift bar (450) directly mounted on a machine (20) for moving the guard rail (210) relative to the rail (310) between a low position and a high position, wherein the load is supported either by the rail (310) or by the guard rail (210). The pivoting lever (410) transforms the vertical upward force exerted by the lift bar (450) into a horizontal force on the guard rail (210) to move it in horizontal translation (Th).

Abstract: The present invention is directed to a handling device for loading and unloading a sheet metal coil. The sheet metal coil may be loaded or unloaded from a storage pallet to a machine such as reel without manual handling in a safe manner for the operator and the material, using an apparatus such as a fork lift truck. This handling device has a gripping member for gripping the coil and a frame bearing the gripping member by a first pivoting pin. The handle device is mounted on a lift truck table by a second pivoting pin. The device also has a controller coupled with the frame designed to move between an inoperative position where the gripping member is placed inside a fixed mast and an operative position where the gripping member is lowered between one or more forks.

Abstract: 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 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.
