VLT Drive Applications


Wrapper

VLT® drives provide very fast accelerations even with high load in wrapping machines and robots. With built-in synchronising and positioning control the VLT® drives make wrapping machines extremely efficient and flexible.
Equipped with VLT® drives, expensive servo systems are saved.

Replace mechanical systems and add flexibility
Wrapping requires precise positioning and synchronising. VLT® operated motors replace mechanical systems and add flexibility.
Dynamic braking of the vertical operation with heavy load optimises the process and reduces mechanical wear.
Positioning, synchronising, and load estimation are features that make wrapping faster and more flexible.

Wrapper features Benefits
Synchronisation/positioning Use of cams
Integrated positioning
Non-linear synchronous motional
sequence on leading axis
Precision stop
Safe stop No additional cabling
Manual shut down of motors
VLT® drive is still functional


Palletiser

VLT® drives provide very fast accelerations even with high load in palletisers. With built-in synchronising and positioning control, the VLT® drives make packing/unpacking machines extremely efficient and flexible.
Equipped with VLT® drives, expensive servo systems are saved.

To move goods, for example from a pallet to a conveyor, requires precise stopping.
Dynamic braking of the vertical operation with heavy load optimises the process and reduces mechanical wear. Positioning, synchronising, and load estimation are features that make palletiser operation faster and more flexible.

Filler/capper

Filler
VLT® drives provide accurate and precise dosing of bottles, flasks, cartons, cans, tubes, and containers. This goes for a wide variety of liquid products that are warm, hot, molten, cold, semi-frozen, viscous, abrasive, particulated, chunky or free flowing. Also acidic or alkaline bases are treated.

Safe blending of propellants
The propellants (CO2, N2 O3) require safe blending of the viscous, abrasive or free flowing liquid and propellant without leaks.
Synchronisation and positioning
With VLT® drives’ wide range of motion control options they allow positioning, synchronising and cam control with almost any motor and feed-back system. Regardless of whether you need an absolute or an incremental feedback system, VLT® drives offers innovative and easy to use motion control solutions.

Capper
Traditionally, the rotating motion necessary to seal the bottles was realized with mechanical components. Rising requirements of flexibility in operation have led to the introduction of servo-drives. Due to the increasing use of cold aseptic filling, it is critical to avoid germ formation in assigned machine components. Special servo-drives are necessary for this.
