If the tubes have already been printed and painted, decoration must not be damaged during transfer. As carefully as possible, the conveyor belt takes the tubes off the chain pins, fixes them on the star wheel by vacuum and finally pushes them onto the mandrels of the big mandrel plate. The speed of conveyor, star wheel and mandrel plate are perfectly matched..
New capping machine A240
In the capping machine everything revolves about the rotating mandrel plate. Depending on the machine type, it realises up to 20 working steps in one circuit. Beside the correct screwing-on or pressing-on of the cap, tasks of the machine are snipping, pressing-on of nipples, membrane welding, torquing or labelling. Several checks guarantee consistently optimum results.
Many roads lead to the capping machine
The caps for tubes are first transported via conveyor belts from a floor-based angled feeder into a vibrating feeder. From there, most caps are led to a capping station through a channel. Very long and slender caps are set in the right position to the tube by a hose feeder.
Multiple checks assure quality
Hinterkopf capping machines do not only work reliably, but provide controlled quality. Several monitoring stations permanently review the most important processes so that one cap suits as perfectly as the other. Once a control station reports an abnormal value the tube is sorted out. The user-friendly touchscreen provides insight into the complex processes within the capping machine.
