摘要:
An apparatus and a method of using a plurality of dual acting cylinders to acquire articles with vacuum cups is disclosed. A robot arm comprises a manipulator movable with the robot arm with the plurality of dual acting cylinders attached to the manipulator. The robot arm is configured to passively conform to a plurality of irregular articles by extending dual acting cylinders from manipulator and moving the manipulator distally with the robot arm to conform to the plurality of irregular articles. The movement causes each dual acting cylinder to passively and proximally retract from the contact of the vacuum cup with a respective irregular article and passively conform the vacuum cups and dual acting cylinders to the plurality of irregular articles. Each vacuum cup can adhere to and can manipulate acquired articles with vacuum.

A vacuum powered system for moving a movable component, such as for raising and lowering a stowage container, includes a vacuum actuator connected between a fixed structure and a movable component. The vacuum actuator includes one or more intake ports that are configured to connect with a source of vacuum for moving the movable component in a first direction to a first position, and one or more bleed valve ports for venting the vacuum actuator to move the movable component in a second direction to a second position. The vacuum actuator may be an air bellows, a single acting linear vacuum actuator, or a dual acting linear vacuum actuator. A guiding system is further provided that includes elongated tracks in a stationary stowage container housing that houses the movable component, and corresponding guide elements on the movable component that slidably engage with the elongated tracks for moving the movable component.

A switching valve is disposed between a pressure fluid supply source and an ejector in a vacuum suction apparatus. A supply port of the switching valve is connected to the pressure fluid supply source, and an outlet port of the switching valve is connected to the ejector. In addition, when suction pads attract a workpiece under suction and a negative pressure becomes constant, a valve body is displaced by a negative pressure supplied through a vacuum port to the switching valve, whereupon communication between the supply port and the outlet port is blocked.

Hydraulic circuit comprising a low-pressure circuit (6) fed by a booster pump (4) that draws from a very-low-pressure reservoir (2), characterized in that this very-low-pressure reservoir (2) is leaktight and has a device for placing the internal volume (12) under negative pressure with respect to atmospheric pressure.
摘要:
The invention relates to an system for supplying a hydraulic circuit with hydraulic fluid. The system includes a working reservoir and an auxiliary reservoir connected to the working reservoir by a hydraulic line. An air pump has an inlet connected to a suction line that opens into a liquid-free portion of the auxiliary reservoir so that a negative pressure can be built up in the auxiliary reservoir relative to the atmospheric ambient pressure. The air pump inlet is also connected to a control line, which comprises a control opening which is covered by the hydraulic fluid in the working reservoir, at least before the air pump is started up.

A force producing device that has a piston movable within a chamber. As the piston is at a first position in the chamber, the chamber is evacuated on both sides of the piston by a vacuum source. The chamber, on one side of the piston, is disconnected from the vacuum source and connected to a source of fluid under pressure for moving the piston toward a second position in the chamber. A striker connected to the piston then imparts a force upon a mass located externally of the chamber.
