Abstract
In order to automatically take samples of radioactive liquids contained in jugs (14) sealed by screw caps, an assembly is proposed which consists of a gripping module (20) for gripping and holding the jug, a module (22) for opening and closing the jugs, and a sampling module (24). The gripping module (20) brings each jug in from of the opening and closing module (20) and fulfils a holding function during the screwing and unscrewing of the cap or plug and during the sampling operation or operations. The sampling module (24) carries out the sampling operations by means of an end piece (138) for the suction and transfer of the liquid into a container (26) for analysis purposes.
Claims10
Assembly for taking liquid samples from jugs sealed by screw caps comprising:
- a module for gripping the jugs, the gripping module having a gripper which in use grippingly holds a jug substantially in line with respect to a vertical axis of the jug;
- means for controlling opening and closing of the gripper;
- means for controlling horizontal displacement of the gripper between a jug gripping station and a jug opening station;
- a module for opening and closing the jugs, the opening and closing module including nippers, the nippers having a generally vertical axis, means for controlling tightening and loosening of the nippers, means for controlling rotation of the nippers, and means for controlling vertical displacement of the nippers;
- and
- a module for sampling liquid including a suction endpiece, the suction endpiece having a substantially vertical axis, means for controlling horizontal displacement of said endpiece between a sampling position, in which the vertical axes of the nippers and the suction endpiece coincide, and a position for distribution of a sampled liquid into a receptacle, and means for controlling vertical displacement of the suction endpiece.
