A flexible TLM packaging line from Schubert for Bahlsen
Bahlsen ’ s new “ Keks ’ n Cream ” creation delivers a lot of taste in the layers of its filled double biscuits . To enable the pastry manufacturer to pack the sensitive products safely , quickly and attractively , a total of 24 pick & place robots had to be accommodated in a machine area of less than ten metres . Moreover , a building support post had to be integrated into the system . A customised TLM machine from Gerhard Schubert masters these challenges while offering flexible packaging options and high output within a minimum of space .
INDIVIDUALLY PLANNED AND COMPACTLY BUILT
The requirements with which the manufacturer approached Gerhard Schubert GmbH , the market leader in top-loading packaging machines , initially sounded like a standard inquiry . But the hall intended for packaging the new product range represented an additional challenge : A freestanding building support post stood in the way of the packaging line , requiring a specially adapted yet compact , high-performance system . “ Since the post could not be removed , we simply integrated it into the somewhat extended system ,” reports Sales Account Manager Michael Voelskow . “ It was especially important for Bahlsen to be able to run other tray sizes in the future as well . Furthermore , low maintenance and low spare parts costs had to be ensured ,” adds Michael Voelskow . The experts at Schubert developed a line that is ideally adapted to the specific conditions , yet still impresses with its extremely compact dimensions .
24 ROBOTS IN THE SMALLEST OF SPACES
At the head of the packaging line , the plastic trays are taken from the magazines and fed into the machine on both sides , so that the product placement into the trays can also run on both sides of the line . A total of 24 pick & place robots work in four
TLM frames . Arranged in pairs , they pick up the biscuits and place them into the trays passing by in the opposite direction . After filling , the trays are rotated by 90 degrees so that they can be discharged lengthwise from the picker line to the subsequent flow-wrapping machine . On one side of the new TLM system , there is also a single storage belt . At the push of a button , individual placement of the biscuits on this grouping belt for flowwrap bag packing without plastic trays can be activated . This works without having to stop the system . The individual discharging and the placing into trays then run in parallel , i . e . simultaneously on both the left and righthand side of the machine .
3D SCANNER FOR QUALITY CONTROL

In the picker line , four 3D scanners ensure that only intact biscuits are detected and enter the packaging . Products containing no filling or less than the specified amount of filling , as well as those not clearly bearing the Leibniz lettering , are rejected . This ensures that only flawless products get into the packages .
