Automatic Pallet Change (APC)

Automatic pallet change (APC) is an intelligent accessory that replaces the standard machine table and significantly increases production productivity.

The system enables a second workpiece to be prepared and set up while one workpiece is being machined, eliminating downtime and shortening the overall machining cycle.

This solution delivers greater effectiveness, smoother production and greater utilisation of operator time. It is designed for reliable continuous operation and can be easily adapted to specific operational needs.

System principle and design

The standard pallet exchange equipment concept is based on the automatic exchange of technological pallets between:

  • Stationary storage stations equipped with manipulators, 
  • and the pallet clamping base located on the machine.

The pallet is locked on the machine by centring pins and mechanically secured; the pallet is released hydraulically. 

The entire exchange process is automatic, without any operator intervention, with high precision and repeatability.

Compatibility with TOS VARNSDORF machines

The APC system is designed for selected machine types: 
WHN 110/130, WHN 13/15, WHR 13, MAXIMA I/II and WHT 110/130.

Thanks to its modular design, the APC can also be integrated into customer-specific configurations or connected to other automation elements, such as automated transport lines in production systems.

ATC system options

  • Change of 2 to 4 pallets using a manipulator 
  • Change of two palettes directly at the store station 
  • Comprehensive inter-machine transport using a manipulator with linear travel 
  • Option to change carousel pallets 

Every solution is tailored to specific technological needs and production line layout. 

Main advantages of the APC system 

  • Minimisation of non-productive time during workpiece clamping and change 
  • Acceleration of the machining process thanks to parallel workpiece preparation 
  • Standardised and proven solution with high reliability 
  • System variability – change of 2 to 4 pallets depending on configuration 
  • Possibility of adapting the clamping surface of pallets according to customer requirements 
  • Carousel pallet applications 
  • Change of 2 to 4 palettes
  • The design of the clamping grooves can be adapted to the customer's requirements
  • Change is also possible for carousel palettes
