摘要:
A handling unit (1) for hollow glass articles including: - a plurality of fingers (10), each configured to engage a corresponding hollow glass article in correspondence of a gripping area (12) and to drag said article along a connection trajectory between a gripping position and a release position, - a displacement mechanism (6, 7A, 7B, 7C, 7D, 7E) of said plurality of fingers (10) between the gripping position and the release position, - wherein each finger (10) of said plurality includes a nozzle (14) which can be supplied by means of pressurized air and arranged in correspondence of said gripping area (12), said nozzle (14) being configured for the ejection of air in a direction tangent with respect to said gripping area (12) so as to set a depression in correspondence of said gripping area (12) to hold a hollow glass article arranged in the gripping area (12) itself, the handling unit (1) being characterized in that it includes at least two control units (RQ, SV; PR, SVV; RQ; PR) of the supply airflow of the nozzles (14), wherein each control unit (RQ, SV; PR, SV; RQ; PR) of the airflow is configured to control at least one corresponding nozzle (14) independently of the nozzles (14) controlled by remaining control units (RQ, SV; PR, SV; RQ; PR) of the airflow.
摘要:
La présente invention concerne un dispositif de préhension et de manipulation pour des objets fragiles en milieu industriel, comprenant au moins deux bras (1) positionnables comme bras de pince d'un engin de manutention de manière à ce que l'écartement entre les bras (1) de la pince soit ajustable. Chaque bras (1) possède une section de forme sensiblement concave, de type en "U", et comporte également des moyens de fixation (2) d'une membrane (3) déformable élastiquement, ladite membrane (3) étant tendue entre les extrémités (4) du "U" de manière à masquer la concavité du bras sur lequel elle est fixée, les bras (1) étant positionnés lors de l'utilisation de sorte que les membranes (3) de chaque bras sont en regard l'une de l'autre et que l'objet à saisir est positionné entre les deux membranes.

The object of the invention is to provide a device for gripping threaded pipe, and like tubular goods, about their outer diameter, and for applying high torque forces required for assembly and disassembly of threaded connections, without causing any surface deformation or structural deformation to said workpieces. The gripping device has an inflatable flexible liner (3) contained within rigid outer shell (5). Axial splines of internal sleeve (7) mate with corresponding splines of flexible liner (3), and distribute torque forces uniformly throughout flexible liner (3). Introduction of fluid pressure into annular bladder (8), through port (6), causes the flexible liner (3) to deform radial inward and thrust friction sleeve (1) into contact with workpiece (4). Movable anti-extrusion rings (2) prevent deformation of the liner into annular space (9), between outer shell (5) and workpiece (4), and also prevent axial wear of flexible liner (3) against outer shell (5).
摘要:
A clamp assembly (12) for controllably gripping an article (10). Automated material handling devices generally require sensor and control devices to adapt the device to variously sized and shaped articles. Also, the application of excess contact force between the clamping device and article may damage vulnerable surfaces and features of the article being handled. The present invention solves the above problem by providing a clamp assembly (12) having opposed, pressurizable gripping members (64, 66). The gripping members (64, 66) each have a compliant, article-contacting surface (67, 68) which form about the article (10) upon pressurization of the gripping members (64, 66). The invention is of particular benefit in handling a wide range of differently sized stepped-diameter shafts.

The invention relates to a method of fixing the windings of a metal strip coil (10) during lifting or transporting and to a device for carrying out this method. According to the invention, in order to fix the central metal strip layers, an expanding device (13) is inserted into the central hole (11) before the lifting and is expanded in such a way that a pressure is exerted on the inner windings. The expanding device is preferably an inflatable body.
