Abstract
In 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, 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 reliably detected.
Claims6
Device (1) for screwing a screw cap onto a container (3), with a spindle (4) which can be driven and a closing head (5) which can be rotated with respect to the spindle, where, between the spindle and the closing head, a magnetic coupling (6) with several permanent magnets (7) which are rotatably connected to the closing heads, characterized in that in the circumferential area of the permanent magnets (7), a preferably inductive detector (8) which determines the state of movement is arranged.
