摘要:
A handling device (1) for objects to be moved in space, comprising a balancing actuator (11) connected between a supporting base (2) and an arm (5) and designed to balance the weight at least of a loading portion (8) connected to the arm (5) in such a way as to keep the loading portion (8) suspended in space. The handling device (1) also comprises movement aid means (14) acting on the mechanical arm (5) and designed to move the mechanical arm (5) relative to the base along a line of movement (6). Said handling device (1) also comprises a control unit (16) which can be operated by the operator and is operatively connected to the movement aid means (14) for operating said movement aid means (14) on command.
摘要:
The device for manipulating objects (2), in particular sacks, by means of suction comprises a hollow body (3) having a contact portion (4) suitable for coming into contact with a surface of the objects (2); vacuum generating means (7) and contact detecting means for detecting contact between the contact portion (4) and the surface of the objects (2). The vacuum generating means (7) are operatively connected to the inside of the hollow body (3) for generating a vacuum suitable for causing adherence of a portion of the surface of the objects (2) to the contact portion (4). The means for detecting the contact between the contact portion (4) and the surface the objects (2) are operationally connected to the vacuum generating means (7) so as to activate the vacuum generating means (7) after contact has been made.
摘要:
Described is a fluid flow rate limiting valve (1), in particular for manipulators, comprising: a chamber (2) defining a main conduit (2a) for the passage of an operating fluid, the chamber (2) having an inlet opening (2i) and a delivery opening (2m) for the fluid; an inlet conduit (3) connected to the inlet opening (2i) of the chamber (2); a delivery conduit (4) connected to the delivery opening (2m) of the chamber (2); a shutter (5) positioned inside the main conduit (2a) of the chamber (2) and movable between an operating position for allowing passage of the fluid and an operating position for at least partly obstructing the passage of the fluid towards the delivery opening (2m), in such a way as to limit the fluid flow rate in the delivery opening (2m). More specifically, the valve (1) comprises: at least one main by-pass channel (6) forming a fluid communication passage between the inlet conduit (3) and the delivery conduit (4); means (7) for regulating the passage section of the main by-pass channel (6); the main by-pass channel (6) allowing or blocking the passage of fluid irrespective of the operating position of the shutter (5).
