Continuous Motion Cap Closing Machine

One of our core competences is designing and building self-contained, continuous motion, cap closing machines. Our automated machines can close caps of various types, sizes, or diameters. They can be easily integrated with production/packaging lines with fixed or flexible production rates. Plastic caps, flip-top caps and dispensing closures can be closed using our machines.

Vibratory feed bowls and reject stations with deflector chutes are integrated in our cap-closing machines. Operators can easily configure our closing machines with touch screen interfaces. Feeder bowls and in-line tracks facilitate continuous flow of product to the continuous motion dial. Eject stations available in our machines divert finished closures into customer-provided packaging containers.

As with all of our machines, the Continuous Motion Cap Closing Machines are programmable and utilize a touch screen user interface. The machines undergo a series of stringent checking processes including 24-hour, non-stop dry cycle run, and multi-stage load testing prior to delivery.

From each and every machine our customers can expect longevity and reliability due to our use of mechanical and servo driven motions. Our skilled work force is all under one roof, allowing for the complete construction, and product accountability, within our shop. We use both conventional and state of the art CAD/CAM and wire EDM machines to fabricate the components.

General Machine Description

The Continuous Motion Cap Closing Machine is a self-contained unit, with a closure feeder bowl, and inline track. The machine is configured with a continuously rotating dial, mounted horizontally to transfer the closure through the closing and inspection processes. The closure is held in position on the dial by cam driven forks. The forks retract while an outer cam rail will allow the spindle to move down on the lid, snapping the lid closed onto the closure. The cam section is mounted on a pneumatic slide equipped with a regulator to allow adjustment of the closing force. If the “open closure” or “missing lid” detection is activated after the closing operation, the closure will be designated as a reject and removed from the dial. A fixed cam will then divert completed assemblies to an eject chute equipped with a pneumatically operated box diverter while an air blow off from under the closure will remove rejects from the dial and blow them into a reject chute.

Standard features:

  • A feeder bowl to load closures.
  • In line track to feed closures to the continuous motion dial.
  • Continuous motion dial with upper, lower and horizontal cam controlled tooling to close closure.
  • The lower dial tooling is equipped with cam driven spindles with tooling.
  • An outer cam will allow each spindle to move up and pivot the lids over the closure.
  • The upper tooling dial is equipped with cam driven spindles with tooling.
  • Good parts eject track and reject station.
  • Two position box diverter.
  • Shift register tracking system will monitor good and bad parts thru the system.
  • Touch screen type operator control panel with message display to indicate functionality and spindle monitoring.
  • Mechanical and Electrical operating manuals.

Each station is mounted on identical station plates for added flexibility, and is constructed with tooling mounted to a ground steel top plate supported by a fabricated steel base. Mechanical, pneumatic and electrical equipment are group mounted on the base. Electrical controls are mounted in NEMA 12 style enclosures and all tooling will be hardened and ground. Machine components can be anodized, plated, or painted as necessary. Pinch points and rotating sections will be guarded to prevent operator injury. Perimeter guarding is electrically interlocked and fabricated with clear polycarbonate panels and extruded aluminum.
