Driven by the rigorous requirements of pharmaceutical packaging, New England Machinery’s new rotary servo cappers also answer the broader market’s desire for added flexibility, efficiency and performance.

The ELAU (interpack Hall 5, Stand D19) servos in use are also well known for their consistent, order-of-magnitude greater torque accuracy and faster, automated torque adjustment compared to clutches or variable frequency drives. But that is only the beginning of the performance benefits.

Pitch ratio and format changes don’t require gearing to be resized, they are simply programmed into a recipe that is selected from the operator panel. The capper can handle a great variety of caps, including child resistant caps and tamper lock collars.

The servo spindle provides a huge difference in controlling the vertical axis of each capping head. A full 8 inches of automated spindle travel allows NEM to handle a very wide range of container shapes and sizes, as well as dip tube insertion.

With a mechanical cam, dropping a dip tube into a container impacts throughput, whereas the servo drives the tube into position under positive control to optimize the capping process.
When container heights change, capping head height is automatically adjusted. A minimum number of change parts are all quick-connect designs.

Bottom line: New England Machinery is achieving more throughput with fewer heads because spindle speed is so well controlled that the turret can be run faster. In some cases, a 6-head capper is achieving the same performance as a conventional 8-head machine.
