Composed of the multiple capping heads mounted on a rotating carousel, the SRAML multi-head rotary capper enables a “direct pick” system that picks up pre-threaded plastic screw caps and applies them to multiple glass or PET bottles at the same time in a continuous, non-stop motion, which makes them extremely efficient and ideal for very large-scale manufacturing lines. Thanks to the magnetic clutch control in the capping heads, the PK capper applies just the perfect amount of pressure and twisting force for the perfect seal and ultimate protection of your bottled product.
- “No bottle — no cap” safety system stops if the bottle is not in place
Method of operation – Pick & place capping of pre-threaded caps:
After the caps have been sorted according to their positions in the centrifugal or mechanical cap sorter, the caps are feed to the capper via an open chute. Chute feeds the cap to the rotating star-wheel, which is transferring the cap to the position, where can be picked by the capping head. The cap can be picked with the cap chuck or cap pincer, depending on the cap shape. Filled bottles are transferred to the turret star-wheel. When bottle is on the capping position, the rotating head with the cap will descend onto them and begin the cap application process. The cap will be applied with the desired torque, provided by the magnetic clutch on the capping head. Bottle anti rotation device can be with the help of toother neck collars for PET bottles, or anti-rotation retaining belt, for glass bottles, or plastic bottles without neck ring. Capped bottles are transported from the turret with the help of a star wheel. The capper is equipped with “no bottle no cap system”, the cap is not feed to the pick unit, if bottle is not present. All the components’ motions are cam operated, allowing repeatability of corking process on all the bottles.
