Abstract:
1. A device for checking a top surface of a neck of a container for the presence of an incline angle measured relatively to a datum plane, said device comprising: a means for holding said container in a predetermined position; a checking part movable into engagement with said surface of said container neck, said checking part being angularly movable in response to contact with said top surface of said container neck, said checking part having an angular orientation correlating with said incline angle of said top surface of said container neck upon engagement therewith; a means for scanning said angular orientation of said checking part, said scanning means comprising: a light transmitter; a mirror mounted on said checking part; a light receiver, said light transmitter adapted to transmit light onto said mirror, said mirror adapted to reflect said light, said light receiver adapted to receive said light reflected from said mirror and to generate a signal in response thereto, said signal being related to said angular orientation; an evaluating unit adapted to receive said signal and derive therefrom a measurement related to said incline angle, said evaluating unit being adapted to compare said measurement with a predetermined threshold value; and an actuator under control of said evaluating unit, said actuator being engageable with said container and adapted to remove it from said device in response to said measurement being beyond said predetermined threshold value.
