摘要: The robot assembly of an industrial robot comprises a stationary robot component (11) and a plurality of movable robot components (12, 13, 14). At least parts of the stationary robot component and the movable robot components have airtight chambers (15, 16, 17) communicating with each other and intended to be kept at a pressure higher than a predetermined level which is higher than an external atmospheric pressure. Robot driving motors (18 to 23) for driving the movable robot components are arranged within the airtight chambers. A driving motor controller (27) for driving and controlling the robot driving motors is connected to the robot driving motors by means of electric cables arranged within the airtight chambers. Pressure switches (25) supply signals to the driving motor controller to stop the robot driving motors, respectively, upon detection of the pressure in the airtight chambers when the pressure in the airtight chambers drops below the predetermined level.

摘要: An acceleration and deceleration system smoothly controls acceleration and deceleration of an electric motor for driving a movable member of a machine tool or a robot. The acceleration and deceleration system has a linear acceleration and deceleration circuit (3) for receiving interpolation data issued from a pulse distributor (5) and effecting a linear acceleration and deceleration computation on the received data, and an exponential acceleration and deceleration circuit (4) for receiving an output signal from the linear acceleration and deceleration circuit (3) and effecting an exponential acceleration and deceleration computation on the output signal, the circuits (3), (4) being connected in series with each other. The exponential acceleration and deceleration circuit (4) reduces abrupt changes of the controlled speed which are a drawback of the linear acceleration and deceleration circuit (3) prevent shocks from being produced when an axis starts moving and is decelerated thereby providing smooth and accurate acceleration and deceleration control.
