Increasing efficiency, availability and redundancy

Crailsheim. At the FachPack 2015 trade show in Nuremberg, Gerhard Schubert GmbH is presenting the prototype for a TLM packaging machine without an electrical cabinet. The reduced electronics further lower the maintenance costs of Schubert’s robot-supported packaging machines. Efficiency, availability and commonality of parts for the systems set an all-new benchmark. Once again with this innovation, Schubert have followed one of their key guiding principles – that of reducing complexity.

An obvious sign of the elimination of traditional electronics for the packaging machine is the smaller head of the TLM machine frame. Since the servo modules of the machine without an electrical cabinet belong within a decentralised control architecture for TLM robots, they no longer require an electrical cabinet. The number of electronic parts has been greatly reduced, leaving only a few components. At the same time, the operation and maintenance of the machine are easier than ever. Customers can therefore take on their packaging tasks based on more user-friendly automation implemented through virtually uninterrupted operation with minimum personnel input.

The machine’s remaining components are equipped with a water cooling feature, which increases the life of the electrical equipment. Moreover, it reduces the system’s waste heat. With a heat exchanger, the customer can make use of the energy from the water cooling. Yet another plus in terms of energy is that Schubert uses drive systems with energy recovery – as with all TLM systems.

At the show, the machine’s functionality will be demonstrated through a pick & place process, whereby four-axle TLM F44 robots will take white and black bears from a white product belt and then place them on Transmoduls in a specific formation.

White bears on a white background – the vision system can detect the products in spite of the very low-contrast environment, thanks to Schubert’s new scanner. The Schubert 3D scanner brings spatial vision to life. The vision system uses the data from the scanner to calculate a height profile and therefore the three-dimensional shape of the products to be packaged. This eliminates the generation of ghosting images through dirt or product residues on the belt. In addition, the 3D-scanner can detect defects – for instance, if a brown sandwich biscuit with brown cream is missing its cover section. Defective products such as these will be removed from the packaging process. Thanks to the 3D scanner, image recognition is effective and more accurate. Customers from all business sectors will benefit from less waste, higher productivity and improved quality.

With uniform product density, the TLM vision system can even detect the weight of each product. This enables individual product formations to be made up within a defined weight range during a grouping process. Depending on the application, the manufacturer can therefore save up to three per cent in raw materials, since less over-production is required to meet the legal standard. Target vs actual comparisons are also possible for stacking height and stacking length in the case of upright box filling.

On screens at the stand, Schubert will also be providing in-depth information on other TLM systems, its thermoforming technology and its filling systems for liquid cosmetic products. Customer examples will clearly illustrate the use of these technologies.

At the FachPack show, Schubert will be exhibiting with its new trade fair concept for the first time. The stand architecture and exhibition graphics accentuate the brand’s innovative power with a striking diagonal line design. Whereas the new TLM machine without an electrical cabinet is being presented in a bright environment, the stand is otherwise decorated in muted grays, offering visitors a pleasant and high quality of stay.
