TS2 transfer system brings ergonomic assembly to life A Bosch Rexroth TS 2 transfer system supplied by TectraAutomation and engineered by Petrichor Concepts has been chosen for a recent upgrade at ASSA ABLOY South Africa, the local manufacturer of security products and systems. Trevor Bruce, engineering manager for Petrichor Concepts, outlines the benefits.

With twelve new variants of the synchro- nous servo motor MS2N, Bosch Rexroth is expanding the performance range of the engine series at the high end. With up to 692 Nm, the maximum torque is almost doubled. These new, compact motors offer high continuous power and an extended speed range to manufacturers. BoschRexrothhasincreasedthecontinu- ouspowerwithinthesmallinstallationspace through optimised electromagnetic design and use of the reluctance effect to create torque. The new frame size MS2N13 com- prises four compact lengths in three cooling variants each: self-cooling, force-ventilated or water cooling. With a continuous torque of up to 345Nmandmaximumspeeds of up to3600 rpm, they areparticularly suited for powerful applications in plastics processing machines,informingtechnologyorinheavy- duty machining. L eading local lock, door and secure access solutions manufacturer, ASSA ABLOY South Africa, recently up- graded its assembly line to a semi- autonomous production system engineered by Petrichor Concepts, a lately acquired and wholly owned subsidiary of FLSmidth South Africa. Accurately moving components to each workstation across the assembly line is achieved using a Bosch Rexroth TS 2 transfer system supplied by Tectra Automation. Aiming to increase its production output of a variety of different lock types and con- figurations, the new assembly line integrates a combination of automated and manu- ally operatedworkstations connected via the 29 m TS 2 conveyor. “Simpler assembly tasks are nowachieved with high-tech robotics, while jobs requir- ing more dexterity are achieved manually,” explains Trevor Bruce, engineering manager for Petrichor Concepts. “Bringing this lean production concept to life required a transfer system providing full 360° pallet movement,

The MS2N motor series is a true all- rounder for all applications in automation and combines dynamics with compact di- mensions and maximum energy efficiency. The motors can be configured flexibly, with awide rangeof shafts, encoders andholding brakes to choose from. Designers can select them in line with their respective requirements.

Enabling this precise handling control acrossthesystemarepneumatictechnologies from Aventics, including the AV05 control bank with Profibus connection, which has 96 digital inputs and 48 outputs connected to Petrichor’s engineered control system architecture. “In addition, the modular, fully custom- isable nature of the Bosch Rexroth TS 2 system enabled us to build a bespoke line with simplified engineering and installation requirements with full technology support from Tectra Automation,” says Bruce. This modern, ergonomic semi-autono- mousassemblylinenowenablesASSAABLOY to produce more locks per operator than before. Inaddition, enhancedqualitymonitor- ing across the assembly process and reduced wastage of materials and consumables helps further reduce production costs and time. TS 2: versatile, robust, adaptable

motors are integrated in the increasingly networked field level of the future. MS2N also plays an integral part in maximising productivity in the new Bosch Rexroth Automation world, ctrlX AUTOMATION. These motors are available in sub- SaharanAfrica through Tectra Automation, a Bosch Rexroth South Africa Group Company. www.boschrexroth.africa/company/ tectra-automation “The TS 2 is a system solution that can be scaledquicklyandeasily for any requirement,” explainsCobus Snymanof TectraAutomation. “The adaptable, modular design allows facto- ries to realise a vast array of system layouts with quick implementation. The system is ideal for any assembly application, from the automotive industry to electronics and elec- trical technology, medical technology and the optical industry.” Tectra Automation is a member of the Bosch Rexroth South Africa Group of Companies. www.hytecgroup.co.za Twice as strong but still compact, the new MS2N13 synchronous servo motor from Bosch Rexroth makes the MS2N series motors even Comprised from standardised modular units that can be combined in many ways to create a single system, the Bosch Rexroth transfer system is designed for transport of workpiecepallets of up to240kg, with several types of combinable conveyor media.
