WLS, a ProMach product brand, has introduced a height-adjustable labeling option for its VR-72 labeler. It automatically adjusts the height of the conveyor, and thus the containers, to effectively change the label height. With this option, the high-speed VR-72 can be programmed to achieve a new label height for an entire batch or dynamically adjust the height of each label for every individual container.
Capable of speeds in excess of 600 containers per minute, the VR-72 applies pressure-sensitive, wrap-around labels made of paper or film to cylindrical, free-standing packages. When equipped with the height-adjustable labeling option, the VR-72 primarily runs vials and bottles containing liquid pharmaceuticals, biotech products, nutraceuticals, personal care products, cosmetics and other consumer goods.
This option is suitable for products that need a printed fill line to be positioned on the container at a particular height, such as pharmaceuticals in which the consumer is going to pour in another solution up to the designated fill line. Placing that fill line on the primary label and changing the label height for each product run allows manufacturers and contract packers to utilize the exact same printed label across multiple batches to minimize label changes, reduce label inventory and eliminate the need for downstream printing processes.
It is also suitable for manufacturers and packers with products that present minor variation in fill level. Users can maximize shelf appeal by dynamically adjusting the height of each label on every single container, relative to the specific fill level. To change the label height dynamically, the VR-72 utilizes a camera to inspect the fill level of each container, quickly identifies the perfect label height based on that fill level and adjusts the conveyor position, as needed.
