BEUMER enables fully automatic loading of bags on trucks

The BEUMER autopac is a system which enables users to automatically load bagged bulk materials like cement on trucks and simultaneously palletise them quickly and with the desired packing pattern.

The process of loading palettes onto trucks can be time-consuming labour intensive – not to mention exhausting.

Let the BEUMER autopac do the heavy lifting and stacking. It is a system which enables users to automatically load bagged bulk materials like cement on trucks and simultaneously palletise them quickly and with the desired packing pattern.

So how does it work? An empty truck slowly stops under the BEUMER autopac. Then, to load and palletise the cement bags, the employee enters the number of bags, the packing pattern and the desired number of rows and layers into the interface.

Laser positioning aids have been mounted to the left and right of the BEUMER autopac. They project the outer contours of the machine with a clearly visible red beam on the loading space, helping the operator to position the loading head on the truck.

From its starting position, the system starts the automatic loading process, bag by bag, directly from the filling machine via belt conveyors onto the truck.

The BEUMER autopac consumes very little energy, is reliable even in dusty environments and can be easily operated and maintained. The machine is also suitable for paper, HDPE and PP valve bags.

“With our BEUMER autopac, we have a system in our product range that can load trucks automatically,” explains Markus Peitzmeier, senior sales manager at BEUMER Group.

“And it does so extremely reliably.”

The use of an electronic bag counting system makes sure that the truck is neither underloaded nor overloaded. Manual corrections are completely omitted.

“The program control recalculates the height setting for each layer,” Mr Peitzmeier describes.

To attain the highest possible degree of stability for the whole load on the truck, and in order to optimally utilise the loading space, two mirror-inverted layers are palletised next to one another.

Two belt conveyors positioned one above the other flatten the bags before the loading process and thus remove the air from them.

After being positioned, the bags are also pressed by the loading head, which makes the stack more compact and more stable. Meanwhile, the next layer is already being prepared. The bag feeding lines can be adapted to the customer's installation conditions. Corresponding technical solutions are available for variable conveyor lines.

Manual truck loading is exhausting and usually requires two people who alternate with their colleagues for each loading process due to the heavy physical work involved. Furthermore, there is the high level of dust formation, which negatively affects the employees' health. During the manual loading process, the loading performance as well as the quality of the bag stacks often fluctuates.

“These problems are eliminated with our BEUMER autopac,” says Mr Peitzmeier.

“One employee is able to operate more than one machine.”

This enables owners to optimise processes, achieve high loading capacities and work very efficiently from bagging up to loading.

Depending on the bag dimensions and their length and width ratio, the user has flexibility in layer formation. Patterns of ten, twelve and twenty bags per layer are possible.

The very low positioning height of the loading head contributes to the gentle handling of the bags, as they are supported during the loading process and not lifted or possibly deformed, as is the case with vacuum suction modules.

This interface is a touch panel with optimised user interface and graphic navigation. This operator panel provides users with an easily understandable and intuitive interaction concept, enabling them to define efficient working sequences.
