Arburg presents efficient injection moulding at the Plastpol

Automation of the future: Six-axis robotic system with Selogica user interface / 2.3-second cycle time proves high-speed capabilities of Allrounder Hidrive

(PresseBox) ( Lossburg, )
With the exhibition of two highend applications at the Plastpol in Kielce from 25 to 28 May 2010, Arburg will be presenting the injection moulding technology of the future. At Stand B-50 in Hall B, trade visitors will be able to view a compact and highly flexible production cell consisting of a vertical Allrounder 375 V machine and a Kuka sixaxis robotic system. The absolute highlight will be the simple programming of the robotic system thanks to the implemented Selogica user interface. In addition, an Allrounder 570 H will provide impressive evidence of the potential of these highperformance hybrid machines: a thinwalled packaging item will be produced in a cycle time of only 2.3 seconds.

Back in 2008, Arburg was already a pioneer for energy efficiency, bringing this important issue into the foreground for the injection moulding industry. "Now we are going one step further, and focusing on 'Efficient production', says Dr. Slawomir Sniady, Arburg subsidiary manager in Poland, explaining the company's strategy. The objective is to achieve maximum product quality at minimum unit cost. The Plastpol exhibits will impressively demonstrate that Arburg provides the perfect means to reach this goal. "The implementation of the Selogica user interface in the control of the sixaxis robotic system, the compact, flexible automation solution, as well as the performance capabilities of the Allrounder Hidrive hybrid series, all show that Arburg repeatedly sets standards when it comes to future trends," says the subsidiary manager, describing the highlights of the trade fair exhibits.

Highperformance hybrid technology

When it comes to speed and productivity, packaging technology makes by far the highest demands. At the same time, machine potential must be utilised to the full without sacrificing quality and availability. The hybrid, highperformance Allrounder Hidrive series is predestined for this task, as it combines maximum production output with short cycles and reduced energy consumption. These qualities are the result of meticulously combining proven servoelectric and hydraulic components from the modular Allrounder system. Servoelectric clamping units have been combined with hydraulic injection units and servoelectric dosage. This combination is further enhanced by performanceadapted hydraulic accumulator technology.

The performance capabilities of this series will be demonstrated most impressively at the Plastpol by an Allrounder 570 H with a highspeed, thinwalled packaging application. On this exhibit, which features a clamping force of 2,000 kN and size 800 injection unit, egg boxes weighing 15.6 grams will be produced in a cycle time of only 2.3 seconds.

The complex made simple with Selogica

Automation solutions are also growing in importance, as the industry aims to produce highquality parts in a costefficient manner. At the same time, programming must remain simple and reliable, despite the increasing complexity. This is ensured by the unique Selogica control system, whose graphicbased sequence programming makes it the perfect human/machine interface for injection moulding machines and robotic systems from Arburg, and for the sixaxis robotic system from Kuka. Consequently, the implementation of the Selogica user interface in the robotic control system brings the user decisive advantages: after only one brief training session, he can independently program and modify robotic sequences. Moreover, the significantly reduced setup work requirements result in shorter setup times and, above all, the synchronisation of robot and machine movements effectively cuts the application's cycle times. This topic will be completed by expert presentations held by Arburg in the context of its Plastpol programme. In addition, the Arburg trade fair stand will also feature a model comprising a clamping unit and sixaxis robotic system, on which trade visitors can test for themselves the simple robotic programming via the Selogica user interface.

Automation: Complex, compact and extremely flexible

An example of the practical application of a sixaxis robotic system of this kind is the complex production cell based on a vertical Allrounder 375 V. Thanks to the small footprint of the vertical machine and high degree of freedom of the robotic equipment, this project system promises extremely high flexibility even in the most restricted spaces. For the automated production of a toy buggy, the robot inserts the metal axles in the mould. In a single injection moulding cycle, the metal axles are encapsulated with plastic wheels, and the roof and chassis are produced. The robot then removes the four individual components and, in a subsequent step, assembles them on the table opposite to produce the finished buggy, which is then removed via a chute.

Project expertise for individual solutions

"The plasticsprocessing industry in Poland demands highend injection moulding solutions with an aim to achieving costefficient yet highquality production. With our modular product range, which permits the customised and industryspecific equipment of machines and systems, we are perfectly positioned to satisfy these requirements," says the Polish subsidiary manager. A further benefit is Arburg's expertise in the field of complex production cells, which incorporate upstream and downstream operations. With Arburg, the customer benefits from a main contractor who designs, implements and commissions the systems and also offers a global aftersales service. "Because close cooperation with the customer is especially important with regard to automation, we have a project engineer here in Michalowice in addition to the Project department at the German Arburg headquarters in Lossburg," says Dr. Slawomir, providing an example of Arburg's allround, intensive customer support, which also covers the automation sector.
