Space-Saving • Gentle on Products • Modular in Design • Always Expandable

With its modular design and resulting high flexibility the WhiteTiger Project fully meets central customer requirements. The PA15 palletizer is one of the project’s core elements - fast but at the same time very gentle when palletizing sensitive products.

One highlight is the floor-level-palletizing, but this can be adapted to handle a wide range of different heights and a variety of infeeds make adaptations to new requirements possible at all times. The modular system in three performance classes, various versions of the placement belt together with component interchangeability ensure maximum flexibility - all that combined with intuitive operation and maintenance. In the high-speed range the system can palletize up to 10 layers / min. at pallet heights up to max. 2800 mm, layer sizes up to 1500 x 1500 mm and layer weights up to150 kg.

This new means of "conveying rather than pushing" conveys rows of products or entire layers instead of pushing them. The belt slides under the bundle, sets it down at its destination, secures it gently - and withdraws just as gently. For a continuous product flow, the product is gently palletized using a placement belt with a very small roller diameter and without grouping or format pushers. This makes the system especially suitable for sensitive products that could otherwise be damaged when pushed (such as flour bags or paper rolls), and thereby minimizes product damage as well as machine malfunctions. Formation of layer patterns containing gaps is also possible due to an innovative, intelligent control system. In addition, the upstream grouping system can grasp individual products and arrange them in any desired formation thus obtaining the highest possible configuration flexibility in layer formation.
The PA15 has an open controls concept and is available with either Siemens (S7-1500) or Rockwell controls.

Space Saving Palletizing Solution:

With this easy to program system you have the best space saving and gentle product handling solution worldwide. Discover this new combination of palletizing with either Siemens or Rockwell controls together with the space saving Layer Handling System TheWave.

Through its unique combination of conveying element and layer gripper TheWave can pick complete product layers from the conveyor line and place them safely and gently on a pallet - regardless of product or layer pattern. TheWave can be used in all sectors of the consumer goods industry and for almost all products. In contrast to conventional systems which use fork or clamp grippers, this compact design results in an enormous space saving of up to 40%. The new Langhammer Articulated Arm Robot AR500 in combination with either Siemens or Rockwell controls guarantees the easiest programming and maintenance. Previous robot programming knowledge is not required as programming of the robot is done directly via the PLC. By combining the Articulated Arm Robot AR500 with TheWave Langhammer offers a coordinated concept for the complete material flow environment, one characterized by extreme accuracy and high-quality palletizing – and everything according to customer requirements – ready to go from a single source.

Function

The process involved in this new Langhammer TheWave system is simple and at the same time fascinating: carried on the gentle wave of the conveyor belt the product is taken up by the split gripper apron. Four-sided compression precisely aligns the layer formation on all sides. Resting on the gripper apron and secured by the four-sided compression plates, the layer is safely transported to the pallet and gently lowered unto it. It makes no difference if the layer pattern contains gaps or if full or half pallet layer patterns are to be transported. Conventional clamping systems exert pressure on the product layer and require interchangeable format parts for layer patterns containing gaps. TheWave does not need format parts for layers with gaps and positions the layer gently and without pressure.
The AR500 Articulated Arm Robot supports highly flexible palletizing possibilities through the use of a large variety of different grippers and operates very reliably as well as economically. Its extreme exactness makes for high quality palletizing and through the simple programmability it can be adapted to new tasks in the shortest of time.

Advantages

• Easy programming and maintenance via the PLC: no robot programming skills required
• Optimal utilization of space and considerable space saving due to its compact design
• Highly flexible palletizing solution allows for any number of layer patterns
• Layer weights of up to 200 kg possible
• Gentle product handling of complete layers
• Consistent and proven Langhammer operating concept allows for easy configuration

Perfect Flexibility

The Linear Robot LR03 is a flexible palletizer and an economical solution for palletizing almost all products in the consumer goods industry and  is ideally suited for palletizing bundles, boxes, bags, standard cases, bakery baskets and packs. In situations with low ceilings and limited space it is the perfect fit. The LR03 impresses with its solid construction, use of high quality components and maintenance friendly design and ensures easy operation. This robot sets standards with a load capacity of up to 500 kg and a possible palletizing height of up to 2800 mm.

Function

The LR03 can be combined with the typical suction, clamp and fork grippers for single and multiple picks and can handle any type of interleaf sheets and empty pallets. In addition layer grippers can grasp complete pallet layers with one pick. The clear design of the color touch-panel makes for easy operation. With the optional MultiPack-Software designing new patterns is done in a matter of minutes. The open control system is based either on Siemens or Rockwell technology, whichever the customer prefers.

Advantages

• Economic articulated arm robot alternative
• Conversion of braking energy into electrical current saves resources and the environment
• Easy and cost saving installation as no support foundation is required
• Easy operation due to clearly defined working area
• Flexible application due to compact and modular design
• Open control system allows for the installation of new pallet configurations at any time

The Allrounder in Pallet Handling

The Layer Palletizer PA8 is suitable for almost all consumer products in packs, cases, crates, bags, etc. The palletizer versions PA81 and PA82 are based on the PA8 base model. PA81 can carry heavy pallet loads and the pallets run through lengthwise - important when palletizing bags. PA82 is designed to handle very heavy pallet loads and pallets can run either lengthwise or crosswise. A typical application for the PA8 palletizer is found in the Hygienic Paper Industry where the standard palletizer palletizes both bundles and small packs.

Function

Products are rotated and orientated in the infeed section as programmed in the HMI. The former pusher transfers the product in sections onto the sliding plate until a full layer has been completed. This sliding plate is located directly over the pallet bay. It opens and transfers the complete layer onto the pallet below, the pallet lift lowers the individual layers one by one, the sliding plate closes and the formation of the next layer begins. Depending on the program selected, an interleaf sheet is now placed onto the new layer. Interleaf sheets can either come off a pallet, a roll or a dispenser. Discharge of the full pallet and positioning of the next empty one is effected automatically.

Advantages

• High output rate with a wide product range
• Precise operation allows for the direct production of sales pallets  
• Simple and quick product changeovers due to toolless format changes
• Minimum space requirement facilitates the integration of the machine into existing production lines
• Modular palletizer design adapts easily to any given layout
• Extendable through the Langhammer building block system

Conveyor and Layer Gripper Combined ‘Simply’

TheWave is a unique combination of a conveyor element with a layer gripper resulting in a machine that can take complete product layers arriving from the conveyor lane and – independent of product type and configuration – place them safely onto a pallet. TheWave can be used in all sectors of the consumer industry branch and for almost all products. Its compact design makes it possible – in contrast to the usual systems using fork or clamp grippers – to save enormously on floor space.

Function

The principle applied in TheWave is as simple as it is fascinating: Carried on the gentle wave of the conveyor belt the product is taken up by the split gripper apron. The four-sided compression aligns the layer formation exactly on all four sides. Positioned on the gripper apron and held in place by the compression unit the product layer is transported to the waiting pallet and gently placed onto it. It makes no difference if the layer pattern contains gaps or if full or half pallets are to be transported. The standard clamp systems exert pressure on the product layer and require exchangeable format parts for layers including gaps. TheWave requires no such parts for configurations with gaps and positions the layer gently and without pressure.

Advantages

• Optimal use of space due to its compact design 
• Reduction of the footprint by more than 40% in comparison to fork gripper systems
• Gentle handling of complete product layers
• Handling of a variety of pallet configurations with only one gripper
• Format parts are not required, thus reducing complexity and freeing warehouse space
