The 2008 TLM Packaging Machine of the Year places cheese slices in retail packages at Karwendel. A prerequisite for the TLM of the Year is that it is based on a good concept. In the case of the Karwendel machine, this is clearly due to the fact that three TLM-F4 robots are used for grouping. These place 200 cheese slices per minute on a grouping belt, which come from a thermoforming machine.
The attentive, qualified observer quickly notices that one of the two TLM-F44 cells is only equipped with one robot arm. As a result, there is a lot of potential should the 200 cheese slices one day become 300. The product enters from the right, past the erecting machine and the filling machine, to the TLM-F44 machines. There, the cheese slices are placed on the grouping belt in accordance with the package content. The grouping belt moves continuously to the right, controlled by the TLM-F44 robots, i.e. in the opposite direction of the boxes. These in turn run to the left from the erecting machine (right). The filling machine (center), equipped with two TLM-F2 robots, picks up the cheese slices from the grouping belt and places them in layers in the retail cartons, which have been erected and glued from flat box blanks. The TLMF2 robot, integrated into the first TLM-F44 machine, closes the filled cartons by gluing the attached lid.
One of the machine’s special features is the filling tools, which place the cheese slices in the retail cartons. The cheese slices are positioned at an angle while they pass the opening of the boxes, i.e. they are more or less ”threaded“ into the boxes. Of course, there is fast convertibility thanks to a simple tool change. Several sizes are packaged on the machine and, like all TLM machines, the Karwendel one is also immediately ready for full operation following the size change, which takes just a few minutes.
