The high-speed label inserter controls intermittently the film advance in precise registration with a printed graphic between two consecutive cutting operations. The steam tunnel develops the heat required to shrink the sleeves and guarantee a perfect adhesion on the bottle.
Shrink sleeve labels are supplied from a roll in the form of a continuous web, unlabeled bottles are transported via an infeed conveyor and then metered via a rotating feedscrew. While the bottles enter the labeler moving past a trigger cell, the labels in web form are opened and formed into a tube by a mandrel, fed and cut in precise registration with a printed graphic, applied to a bottle which is then conveyed up to a steam tunnel.
We are able to supply all the automation products for shrink sleeve label applicator, including the logic and motion or hybrid controller. All motors, drives, position sensors, safety devices, temperature sensors and other panel components. All are easy to integrate and carry the wellknown Omron brand of quality and reliability.
The registration mark printed on the label is used to check the feed and to compensate for any slippage or positioning errors. The registration control works by measuring any error on the current move and applying a correction to the next. The NJ-controller captures the label registration event and synchronizes the label feed with the master encoder axis to place the label on the article at the right moment.
The NJ-controller with EtherCAT synchronises all machine movements according the master encoder position. The NJ-controller generates a pair of continuous bell-shaped speed profiles which precisely control acceleration and deceleration of the film advance wheels and ejector wheels as a function of the angle of rotation of the master encoder.
Manually creating cam profiles can involve intense calculations and a deep understanding of motion control. The Sysmac Studio’s cam profile editor offers an easy to use tool in designing electronic cam profile. Those profiles can be pre-programmed and stored in the memory of the controller. When a different cam profile is needed during machine operation, a switch instruction can be executed in the user-program via the HMI. This reduces product changeovers to mere software commands.
The synchronisation of the film advance and the sleeve ejection with cam profiles guarantees absence of vibration at any operating speed. During operation, the speed can be change via the NS screen without stopping the machine and missing any placement of a label to the bottle.
