TIP C 2103 Replacement “AMK Light” of Obsolete Drives V1 & V2 at the Ream Discharge

TIP C 2103 Replacement “AMK Light” of Drives V1 & V2 at Ream Discharge

Machine Model for Improvement

All E.C.H. Will cut-size sheeters type SLK 440 and SLK 480 equipped with single ream discharge conveyor with Contraves drive system

Description of Improvement

All Contraves motors, controllers and HRU, PCU, ETU drive systems with encoders for the V1 and V2 drives at the ream discharge are obsolete. Any breakdown of these parts will cause an extensive and expensive unplanned stop in production. 

This low cost upgrade to replace only obsolete parts greatly improves machine availability.The Contraves motors are exchanged for maintenance-free, state-of-the-art AMK AC servo drive motors and the Contraves drive components in the existing electrical cabinets are replaced by modern AMK drive components. This new drive system also reduces the number of mechanical parts such as universal joint shaft and coupling. The use of just one type of motor and one type of controller reduces the number of spare parts needed. New cables to and from the controllers and motors are included in the scope of supply.

The new AMK drive system enables automatic ream gap compensation after an interruption in sheet count, for example when sheets are rejected at sheet reject gate (sheets with splices). In addition, an optimum ream discharge speed ramp control further improves synchronization to the ream wrapper as well as overall performance.

Benefits

  • Low cost investment: replacement of obsolete drive parts using existing electrical cabinets
  • Improved machine availability and optimized ream discharge speed ramp control
  • Modern AMK system with maintenance-free AC motors

A sheeter that we had planned especially for our lightweight specialty papers has become an all-round smart sheeter that can process even heavy grammages up to 300 gsm with maximum cutting accuracy.
