High level palletizing technology

At K 2013, the BEUMER Group presented its expertise as a system provider for the plastics producing industry. The company’s extensive portfolio also includes innovative solutions in the palletising and packaging fields. The BEUMER paletpac high-performance layer palletiser stacks bags of granulate or high-quality pigments on pallets of all common sizes up to a pack height of 2,400 mm flexibly, with geometrical accuracy and extreme stability. The user can quickly and easily set the required parameters.Depending on the product requirements, the BEUMER paletpac is fitted with a rotary clamp or double belt turning device which moves the filled bags quickly and gently into the required position.

With the robotpac, the BEUMER Group also offers a space-saving, fully automatic articulated robot which is able to perform complex palletizing and depalletising tasks accurately and efficiently. The robotpac not only stacks bags economically and with millimeter accuracy but also cartons, boxes, canisters and trays. BEUMER has developed appropriate, flexibly exchangeable gripper systems for every packaged product.

The BEUMER stretch hood M high-performance packaging machine packages stacked bags quickly, reliably and permanently and is designed for a number of film thicknesses. It can flexibly deal with different pallet and film formats and is distinguished by high throughput and reliable film handling. The low energy consumption, low compressed air requirement and the ability to process recyclable packaging film make the BEUMER stretch hood M an efficient and environmentally friendly pallet-packaging option.

Efficient handling system

Another system, the BEUMER autopac, loads bagged materials like cement directly from the packing machine onto the truck bed. The bags are palletised automatically in stacked rows or patterns. The system is particularly efficient in emerging market nations, where the transshipment of bagged bulked goods is increasing and labour costs are climbing.

The user can move the BEUMER autopac to its starting position from the control desk. Then, the user defines the number of rows or layers and enters the number of bags to be loaded. The loading process then happens automatically. For each layer, the control program recalculates the height setting. This eliminates readjustments. The machine can load bags in double patterns of five or ten bags. In order to attain the highest possible degree of stability for the whole load on the truck, and in order to optimally utilise the truck bed, two mirror-inverted layers are always palletised next to one another. The bags are flattened by the loading process using two stacked belt conveyors, which releases the air from the bags. After being positioned, the bags are also pressed by the loading head, which makes the stack more compact and more stable. The bag feeding lines can be adjusted to the installation conditions.

Corresponding technical solutions are available for variable conveying lines. The bags are handled gently. Unlike on the systems from other suppliers, where bags are suctioned and lifted, the bags are not deformed by the BEUMER autopac. This is primarily advantageous when loading woven fabric bags, because it prevents the bags from breaking and stops material from being suctioned up into the vacuum filter.An electronic counting device ensures that the truck is not loaded too lightly or too heavily.
