Cylinder stroke: 300mm
Pad stroke below printer: 180mm
This applicator is an optional device to use with label printers of the Compa or Compa II series for automatically applying the printed label onto the product. The labels are transferred with a pad, which moves between the two positions, starting position and labeling position, by a compressed-air driven pneumatic cylinder. In the starting position, the label is picked up from the printer. A sensor at the cylinder signals when the pad is in the starting position. The label is removed from the carrier ribbon directly at the dispense edge of the printer. It is sucked on the pad by a vacuum via drillings at the bottom of the pad. For support, the label is also blown against the pad (supporting air) with an air current coming from a blow tube. The correct transfer of the label is controlled by a vacuum sensor.
Next，the pad is moved down into the labeling position. Reaching the labeling position is confirmed by another sensor (labeling position sensor). In the labeling position the label is transferred onto the product. While the pad is moving back into the starting position, the vacuum sensor checks whether the label has been removed from the pad. The supporting air and the vacuum as well as the speed of the cylinder are adjustable. That way the applicator can be adapted to different label materials and sizes. For integration into a super ordinated process the printers are equipped with ‘Dispenser I/O’.
Tamp Pad
During the print and apply cycle the product remain fixed. The universal tamp is covered by a foil. According to the size of the label the holes can be pierced. The tamp pads are customized to the dimensions of the label sizes on request.
Blow Pad
For non-applying pressure to sensitive products the label can be blown onto the product with the supporting air jet stream. The print and apply cycle performs in a fixed position or in a linear movement of the product. The blow pad moves to a preadjusted position approx. 10mm away from the product.
Roll-on Pad
In the starting position the label is forwarded until touching the roller of the roll on pad. At the labelling position the roller is pressed onto the product. Then the label is applied and rolled on by the movement of the product.
