Robotic Handling Raises Sawing Productivity Volker Bühler, group manager for robotics at German sawing machine and storage system manufacturer, Kasto, describes the widening choice of automation systems on offer to minimise labour costs and increase production output from the company’s circular sawing and bandsawing machines. The production solutions are available in the UK and Ireland through the firm’s subsidiary in Milton Keynes. Industrial robots make production more flexible and efficient, from batch sizes of one to large volumes. They also improve working conditions for operators and can significantly reduce costs in stock holding and manufacturing operations. More and more, operators of sawing systems are automating them with robots, as they are fast, reliable, precise and if necessary can work continuously 24 hours a day without human intervention. Robotic systems are taking over numerous process steps following sawing, starting with removal of the cut pieces, continuing through deburring, chamfering, measuring and marking and on to weighing, sorting and stacking on pallets or in containers. The parts can be transferred to a driverless transport system and taken elsewhere in a warehouse or factory. Automation starts with material feeding. Stock to be cut can be supplied to a machine by means of a roller conveyor or magazine, for example, sparing workers the effort of lifting and reducing the risk of injuries. Depending on how it is equipped, the sawing machine can run attended, with the control system holding all parameters of a job including material diameter, band speed, rate of downfeed, cut length and number of parts. Mr Bühler commented, “In complex processes involving numerous work steps, we use combinations of different robots, grippers and other end effectors. “When large quantities of material with only a few different component geometries are sawn, it is relatively easy to automate the downstream processes. 14 TUBE NEWS June 2018
