Cap Elevators

Zalkin cap elevators supply a metered and controlled quantity of caps to rotary cap orienters at speeds up to 2,000 cpm (120,000 cph).

They are designed to perform two primary functions:

  1. Supply a metered quantity of closures from the bins or hoppers where they have been loaded, and
  2. Deliver these closures to the cap orientation system at the required elevation.

Zalkin cap elevators are available for a wide range of cap types and sizes including:

  • Screw-on closures, for plastic screw caps
  • Roll-on closures, for aluminum caps
  • Push-in closures, for T-corks, stoppers, and plugs
  • Snap-on closures, for snap-caps and lids
  • Screw-on + roll-on, for TOPP (Torque On Pilfer Proof) wine bottle closures
  • Insert + close (for pumps and triggers)

They are compatible with the full range of Zalkin capping system technologies including rotary monobloc, rotary freestanding and single-head cappers.

They employ cleated belts to gently feed caps into capping systems and, if required, transport them to the elevation required by the cap orienter.

The cap bin size and elevation angle can be optimized for each application and line layout.

Zalkin offers two cap elevator models:
  • Inclined Cap Elevators: Meter, elevate and supply closures via an inclined cleated belt to the elevation required to feed the cap orienter. These models are typically freestanding units installed on the production floor and they transport closures from floor level to the cap orienter located above the capping turret.
  • Vertical Cap Elevators: Meter, elevate and supply closures via a vertical cleated belt to the elevation required to feed the cap orienter. They are ideal for closures that require gentle handling. Available models are typically freestanding units installed on the production floor and they transport closures from floor level to the cap orienter located above the capping turret. Vertical elevators are typically used for small footprint requirements.
