Abstract
A machine for de-capping containers having screw caps is responsive to the presence or absence of a cap on a container and includes an annular body mounted for rotation about a vertical axis and for upward and downward movement towards and away from a container. The body carries on its periphery vertical arms which are pivotable about tangentially extending axes, the lower ends of the arms carrying tools operable to grip the cap. Coaxially within the body is a plunger-like probe which is spring urged downward relative to the body and which operates a valve controlling a supply of pressure fluid to motors for operating the arms to grip a cap. If the probe contacts a cap on a container the valve is opened by the relative movement of the probe and body to operate the motors to cause the cap to be gripped. If no cap is present on the container the valve remains closed and the arms do not operate.
