Abstract
A device for screwing a screw cap onto a container with a magnetic coupling arranged between a spindle which can be driven and the closing head, and in the circumferential area of permanent magnets connected to the closing head, an inductive detector for determining the state of motion is provided. As a result, the simplest means are provided to allow the monitoring of the number of revolutions of the closing head, and defects, such as incorrect container clamping, incorrect closing cone and incorrect threadings, can be readily detected.
Claims12
Device (1) for screwing a screw cap onto a container (3), comprising a spindle (4) which can be driven, a closing head (5) which can be rotated with respect to the spindle, a magnetic coupling (6) between the spindle and the closing head (5), a plurality of permanent magnets (7) rotatably connected to the closing head, and a detector (8) arranged to determine a state of movement of the permanent magnets (7).
Device (1) for screwing a screw cap onto a container (3), the device comprising:
- a spindle (4) which can be driven;
- a closing head (5) which moves along a circular path with respect to the spindle;
- a magnetic coupling (6) between the spindle and the closing head (5);
- a plurality of permanent magnets (7) connected to the closing head;
- and
- a detector (8) arranged in a stationary position on the circular path of the closing head (5) at the height of the permanent magnets (7) to determine a state of movement of the permanent magnets.
