Metering apparatus with damage monitoring

摘要

Packaging installation with a metering apparatus and method for monitoring damage in a packaging installation in which packs (19) which are to be filled can be charged with the contents in each case by means of a metering apparatus (01) designed according to one of Claims 1 to 8, wherein —the vibrations of the wall of the dispensing container (02) are measured at least during operation of the stirrer (06) and/or of the metering screw (05), —the measured values are evaluated by the vibration evaluator (10), —deviations in the vibration behavior are detected and compared with limit values stored in the vibration evaluator (10), —when the limit values are exceeded, this indicates with sufficient probability, that the stirrer (06) or the metering screw (05) is in contact with the dispensing container (02), —an alarm is triggered by means of the vibration evaluator (10).

1. A metering apparatus for metering free-flowing materials arranged on a packaging machine, said metering apparatus comprising:
a delivery container having a funnel and a tube an agitator arranged in the funnel a metering screw arranged in the delivery container; a vibration sensor sensing vibration of the delivery container; and a vibration evaluator, wherein a change in a vibration of the delivery container resulting from contact of at least one of the agitator and the metering screw with the delivery container is sensed by the vibration sensor and detected by the vibration evaluator.
