Economical drive, linear and lead screw technology and rollers for flexible adjustable labellers

• What was needed: Linear axes for format adjustments, linear guides and carriages for manual adjustments, lead screws and lead screw nuts for height adjustments, knife edge rollers as guide rollers
• Requirements: The company was looking for a cost-effective solution that would work reliably and meet all the technical requirements of the labelling unit, as well as allowing the adjustment unit to be quickly and modularly installed in the labeller
• Industry: Packaging systems, food industry
• Success for the customer: Our linear guides, linear axes, lead screws and rollers have a long service life and are insensitive to dust and dirt. The high repeatability, precision and speed of the drylin components reduced the batch changeover time of the "Tamper Evident", so that further collaboration is already planned.

Bluhm Systeme GmbH has been collaborating closely with igus on its labelling systems for several years now. The impetus for this came from a customer enquiry for a labeller with flexible format adjustment. Specifically, the customer asked for a device that can apply labels in different sizes and whose positioning width can be flexibly adapted to the product to be labelled.
While searching for a suitable solution for the desired adjustment unit, the manufacturer of labelling systems came across our product portfolio. Three things in particular were decisive for the manufacturer: he was looking for a cost-effective solution that would also work reliably and fulfil all the technical requirements of the labelling unit.
The result is the "Tamper Evident," a compact labeller that can apply various seal labels to products of different sizes in the pharmaceutical, food and cosmetics industries. Initially, the employees of Bluhm Systeme GmbH assembled our components for the adjustment unit themselves and installed them on the Tamper Evident. However, the assembly turned out to be very time-consuming. Instead, the manufacturer wanted to make the process more effective and speed up the installation of the adjustment unit in the Tamper Evident. Finally, personal advice regarding this was sought.

To simplify the process for Bluhm and shorten assembly times, the customer was offered a ready-to-install format adjustment system without further ado.
The drylin linear axes and linear guides used not only give the Tamper Evident with its adjustment unit maximum flexibility when adjusting the labeller. They are also resistant to dust and dirt, making the labeller also suitable for harsh environments. In addition, the linear guides operate without additional lubrication, since their sliding elements contain incorporated lubricants. This not only saves the user maintenance time later on, but also costs for maintenance and lubricants. The long service life of drylin linear and drive technology enables Bluhm Systeme GmbH to supply its customers with a product of the highest quality. With the repeatability, precision and speed of the drylin components, the batch change time of the Tamper Evident could be reduced. The labeller can apply 500 seal labels per minute. Here, every second that you can save on the adjustment pays off. This is why the complete automation of label changeover and format setting is a topic that is consistently pursued at Bluhm. It saves additional time and reduces sources of error. The company also uses dryspin lead screw technology for lubrication-free height adjustments, as well as iglidur knife edge rollers for low-friction and FDA-compliant deflections. Further co-operation is already planned for the future, as demand for the machines continues to grow.
