Digital Printing on Bottles

Task

• Highly dynamic positioning for multi-color printing and the drying process on packaging such as bottles or tubes
• Rotation of the workpiece during the printing process 
• Print head movement

Solution

• Torque Rotary Table TO for fast positioning of the workpieces under the print heads
• ST rotary units for rotating the workpiece synchronized with the linear movement of the print head with air supply through the center 
• Customer-specific linear motor axis to meet the limited space available in the print head 

Benefits

• High speed positioning with output speeds of up to 80 min-1 in combination with a high acceleration torque.
• Measuring system with high resolution in combination with optimized positioning accuracy needed for workpiece rotation and synchronously moved linear axis
• Good print image with an accuracy of the individual points of approx. 0.02mm required
