Linear robotic systems

Individual parts management

Our linear robotic systems feature a high degree of adaptability and a compact design. Here you can see, for example, a MULTILIFT V performing complete assembly or in human-robot cooperation, how a MULTILIFT H gently removes delicate items, or how a MULTILIFT SELECT can effectively handle heavy moulded parts.

Robots in action

A playful demonstration of the potential of automation
The ARBURG Technology Days 2016 included a light-hearted demonstration of just what automation can achieve: a picker, linear robotic system and six-axis robot were used to help a fleet of Bruder model cars negotiate an obstacle course.

An INTEGRALPICKER V used its high-speed pick and place movements to load and unload two dumper trucks and a tractor, while a linear MULTILIFT V robotic system made sure that the vehicles covered a great deal of ground in dynamic style. In addition, a six-axis robot used its repertoire of flexible 3D movements to handle a tractor. The three automation units worked hand-in-hand and communicated with one another by means of peripheral equipment interfaces.

Human-robot interaction

Efficient automation of smaller unit volumes
When operators and robotic systems work hand-in-hand, automation solutions can be worthwhile even for the production of small and medium-sized batches. In the example shown here, feed systems for inserts are dispensed with, and the gripper equipment is simplified. Fast and flexible product changeovers are therefore possible.

Protected by a light curtain, the operator manually positions the axles of a toy buggy in the gripper of a MULTILIFT V during the injection moulding cycle. Firstly, this human/robotic interaction reduces the capital expenditure on automation. Secondly, thanks to the reproducible, ergonomic processes, it enhances process reliability and productivity. What's more, changeover is much simpler and the time a fully automated system requires for this step is shortened from 5 to 3.5 hours.

Buggy

Robotic system performs complete assembly
A hydraulic ALLROUNDER S injection moulding machine produces a four-piece buggy: the wheels are moulded onto two metal axles while the roof and chassis are produced simultaneously. A vertically-operating MULTILIFT V robotic systems performs insertion and removal of the individual parts and complete assembly of the buggy.

The metal axles of the toy car are separated automatically from bulk. They are then inserted into the mould on the nozzle side by the MULTILIFT V, which simultaneously removes the finished parts on the ejector side. The mould opening time can be reduced significantly through synchronisation of the robot and machine movements. High process reliability is achieved through camera monitoring of the assembly steps, including quality control. 

Optical waveguide

High-precision microstructures
The electric injection moulding machines of the ALLDRIVE series are predestined for high-precision optical applications such as the automated production of optical waveguides made from PC. Maximum part quality and precision are required here owing to the surface microstructures, which measure 5 nm.

Reliable replication of the microstructures is achieved through a high mould temperature of 120°C. The horizontally-operating MULTILIFT H robotic system gently removes the optical waveguides and transfers them to an optical testing station. All the peripherals are integrated in the SELOGICA control system so that the entire production process can be monitored seamlessly and centrally.

Pipe junction

Complex core pull technology
In order to produce a Y junction for a sewage pipe with a diameter of 110 mm, a mould featuring complex core pull technology and collapsible core segments is used. The three hydraulic core pulls are fully integrated in the SELOGICA control system.

A sequence with synchronised side cores prevents damage to the mould; the main core moves separately and always ahead of the side cores. The pipe junction is produced on a hydraulic ALLROUNDER 820 S injection moulding machine. A MULTILIFT SELECT robotic system ensures gentle removal of the component, which weighs 505 g.
