Perfect for small to medium businesses who need maximum efficiency but not necessarily a massive production volume, the SRAML single-head capping machine applies non-threaded aluminium ROPP caps onto glass or PET bottles by rolling the thread on the cap and sealing it tightly.
Composed of a capping station with a single powerful capping head placed above a star-wheel which feeds the bottles to the capper, the unit enables a “direct pick” system, minimizing the contact between the screw cap and the machine. The capping station is equipped with the cap distributor, the chute with the releasing head and the capping head in stainless steel, complete with rolls that seal the aluminium screw cap to the bottle.
- “No cap — no roll” system stops if the bottle is not in place
Method of operation:
Caps are loaded in the vibrating hopper – feeder, where are correctly positioned, and distributed into the in a towing shoe. From there are directly picked up by filled bottle, when being transported with the help of a star-wheel trough the capper, in a smooth step motion. Bottles with applied caps are transferred to the sealing position, where the rotating sealing head descend onto them and begin the cap application process. The sealing head will first apply a top load to the closure, to compress the liner within the cap, to achieve a proper seal with the land of the bottle finish. The arms of the sealing head are then pushed inward and the thread rollers and pilfer rollers contact the cap to form it, so that it adopts the shape of the thread and pilfer grove of the neck finish of the bottle.If a cap is missing, a safety plunger prevents contact between the rollers and the bottle neck finish. All the components’ motions are cam operated, allowing repeatability of capping process on all the bottles. Capped bottles transported from the turret with the help of a same star wheel.
Main features:
- Vibrating cap sorter-feeder mounted on top of the machine.
- Cap descending chute with minimum cap level sensor.
- Towing shoe mounted on chute
- Bottle transfer star-wheel with smooth step motion.
- Roll on sealing heads, with no cap no roll safety system(for one cap size).
- Capping head motion unit, cam operated.
- Manual height adjustment of the top part of the capper, with height indicator.
Additional applications:
- Cap chute with towing shoe, for additional cap.
- Additional roll on capping head for additional cap.
- Nitrogen injection in the bottle neck, before cap distribution.
- Electrical height adjustment.
