Until recently, control of the impact strength at multiple positions of the bottle had been manually tested. A newly developed machine from Heye-Glas offers the possibility to carry out these inspections on a number of articles automatically. The articles to be inspected are conveyed from a storage conveyor onto the conveyor of the Automatic Pendulum Impact Tester, where they are pushed piece-by-piece onto a turntable by means of a transfer pusher. A clamping cylinder presses the container against a backstop. A pendulum carries out up to a maximum of 12 strokes on the circumferece of the container. After each impact the article is turned by an angle which corresponds with the number of strokes. If the article withstands the impacts, the release height is automatically increased by the amount prescribed in the rule and the inspection will be continued.
