Closing machines vary depending on the application—cans that need lids, bottles that need to be capped or corked, boxes that need to be folded and glued, etc. Sensors can be used to see containers before they arrive at the closing station, either to stop infeed in the event of a jam or when commanded to do so by the control system. Another sensor is used to ensure the container is positioned properly under the closing apparatus. Additional sensors continually check the cap/lid supply and subsequently confirm proper cap placement on the bottle before sending it off to the next station. SICK has the right sensor for your specific application.
