Motion control solutions - product labeling

Back to index

Labels are affixed to a moving bottle. A sensor (fed into the high speed position latch of the controller) on the conveyor detects an oncoming bottle, at which point the label is indexed. A second sensor on the label accurately detects the label position allowing it to be accurately placed onto the bottle.

A servo axis on the conveyor is used to control the machine speed. This application can be solved using position lock, with a clutch (Mint FOLLOW keyword) to allow controlled acceleration and deceleration of the label while at the same time maintaining position with the conveyor. A position offset (Mint OFFSET keyword) corrects for any error between the bottle and the label.

Special features used:

  • Auxiliary encoder for product synchronization
  • Software position lock with clutch distance to engage and disengage the label movement
  • High speed position latch to accurately measure product and label position
  • Comms array to pass recipe data to and from the HMI

Products:

All of Baldor's motion control products can be used to solve this multi-axis application
