While the Allrounder 920 H will produce a technical part at the Fakuma 2017, the Allrounder 1120 H will form part of an innovative turnkey solution, producing the familiar folding step stool in the Arburg design in a cycle time of 60 seconds. The eight individual parts will be handled by a Multilift V 40 linear robotic system and assembled ready for use by means of a six-axis robot and assembly station.
Industry 4.0: Practical example: rubber tension belts
Rising costs, efficiency and scheduling pressures, greater diversity with smaller production orders and increasing automation all lead to increasingly complex processes that should nevertheless remain easy to control and economically efficient. This topic, which is gaining increasing attention under the headings of "Industry 4.0", "Digital Transformation" and "Smart Factory", calls for host computer systems like the ALS and the integration of IT solutions in the production process. Arburg will use the example of elastic tension belts to show how customer wishes expressed online can be integrated into the ongoing injection moulding process. In industrial practice, such flexible production in single-unit batches is ideal for cable assemblies for the automotive industry, for example. In the application presented at the trade fair, visitors will be able to choose between rubber bands of different lengths and in different colours, as well as end pieces in hook/hook, hook/eyelet or eyelet/eyelet combinations and have their order recorded directly at a terminal. A vertical Allrounder 375 V with a 4-cavity mould (two cavities each for the eyelet and hook) flexibly produces the desired variant from shot-to-shot. The two corresponding cavities and hot-runner nozzles are controlled by means of slides. The inserts are handled by a six-axis robot.
Turnkey: LSR/LSR watches produced within the injection moulding cycle
LSR/LSR wristwatches require complex manufacturing processes and set the standard for what can currently be achieved in the processing of liquid silicone. The centrepiece of the turnkey system is an electric two-component Allrounder 570 A. Two two-tone wrist straps made from the LSR materials Silopren 2670 (hardness 70 Shore A) and 2620 (hardness 20 Shore A) are produced fully automatically in a cycle time of 75 seconds. The 2+2-cavity mould is from Rico, the dosing system from Reinhardt-Technik and the temperature control system from Regloplas. A Multilift V 15 linear robotic system copes with the demanding task of handling the flexible parts. The assembly of the watch mechanisms to complete the ready-to-use wristwatch takes place automatically within the injection moulding cycle.
Packaging technology: four IML tubs in a cycle time of less than two seconds
A packaging version of the Allrounder 570 H specially designed for thin-walled parts demonstrates a high-speed application for the packaging industry. The production cell produces four IML tubs from PP in a cycle time of less than two seconds. The mould and the automation system for inserting the IML labels and removing and stacking the 3.55-gram decorated finished parts are from Brink.
