Handhabungsvorrichtung wie Linear-, Greif-, Spann-, Dreh- oder Schwenkvorrichtung, mit einem Grundgehäuse (100), mit wenigsten einem im Grundgehäuse (100) beweglich angeordneten Stellglied, mit einem sich axial erstreckenden Zylinder und einem mit dem Stellglied bewegungsgekoppelten Kolben, der im Zylinder axial beweglich angeordnet ist, wobei ein Ventil (106) angeordnet ist, das auf einer Seite des Kolbens mit dem Zylinder verbunden ist, wobei durch das Ventil (106) zur Beeinflussung einer axialen Lage des Kolbens entweder eine Druckquelle oder eine Referenzdruckquelle, insbesondere Atmosphärendruck, mit dem Zylinder verbindbar ist, dadurch gekennzeichnet, dass in einer Verbindung zwischen dem Ventil (106) und dem Zylinder ein Schaltventil (110) zum wahlweisen Öffnen oder Schließen der Verbindung angeordnet ist.
摘要:
The invention relates to an overload protection device (1) comprising a housing (2), which is designed to be fixed to a manipulation device. Said overload protection device comprises a tool holder (3) for fixing a tool that is attached to the housing in a displaceable manner, a pre-tensioning unit (4) for generating a pre-tensioning force between the housing and the tool holder, said pre-tensioning unit being configured as a plunger assembly with a pump plunger, which can be impinged by a medium and a switching unit (5) that operates by means of relative displacements between the housing and the tool holder. The invention is characterised in that the switching unit has at least one electrically conductive switching surface (6) and at least one electrically conductive contact element (7) that can be brought into electrical contact with the switching surface, said switching surface (6) and the contact element (7) being provided on opposing surface sections (8) of the tool holder and the housing. The contact element (7) is configured as a sealing element, which seals off at least sections of the pump plunger from the switching surface (6).

The invention relates to a polling system for a moved machine component, comprising a polling subunit that is to be disposed at the machine component end and is provided with at least one switch which operates without power in a certain state of the machine component or a certain position of a part of the machine component, a radio transmitter unit that evaluates the switching modes of the switch and transmits the evaluated switching signals with digital radio switching signals, and an electric power source for supplying the radio transmitter unit. The inventive polling system further comprises a radio receiver unit which is stationary relative to the polling subunit and is used for receiving and evaluating, forwarding and/or displaying the signals received from the radio transmitter unit.

The invention relates to a drive, especially for rotary, pivotal or linear drive units, comprising a working piston (16), housed in a cylinder (12) of a housing (14), impinged by fluidic pressure media and displaced in the axial direction. The invention is characterized in that mechanical coupling elements (22, 24) are disposed on the working piston and can be coupled with a motor (30) in such a manner that the motor slows down and/or drives the working piston in the axial direction. The invention also relates to rotary, pivotal or linear drive units comprising said drive and to a method for operating a drive or a rotary, pivotal or linear drive unit.
