WEMO has launched new X-Line linear robots that can carry out fast removal of most different plastics part thanks to their dynamic motion sequences.
Robot WEMO X-Line 400 for injection moulding machineswith clamping forces from 800 to 1,500 kN
The three servo-driven axes are designed for fast movements with repeat accuracy increasing productivity by nearly 20 percent, guaranteeing stability and precision. For example, the different axes are made of laser-welded square profiles of heavy duty steel.
They are extremely rigid and have a lower weight compared to usual aluminium profiles making the motion sequences faster and more dynamic as less mass needs to be moved. The steel square tubes allow a slimmer design of the axes. This saves opening strokes, reduces cycle times and increases working load.
The free released axes function eliminates forces on the vertical arm ensuring a longer life of bearings and linear guides and reduces the need for maintenance. A planetary gear guarantees fast acceleration of the belt drive of the X axis and the Z-axis is driven by a rack. The complete in-house gripper system has been revised and improved. All drives, gears and the fast changing system have been optimised.
For all their handling units, WEMO paid particular attention to cost and energy savings. With the integrated, electrically powered vacuum unit, for example, compressed air consumption can be reduced by nearly 80 percent compared with conventional systems. The Ethernet Powerlink-Bus-System ensures fast reactions and precise synchronisation with response time below 0.5 milliseconds.
The intuitive operator interface featuring a touch screen allows quick and easy handling programming, with the process sequences of the WIPS handling Control (WEMO Intuitive Programming System) divided into five predefined functions. Pictograms guide the operator safely and step by step through the robot programme.
WEMO X-Line-robots are available in six different sizes for injection moulding machines from 750 up to 5,000 kN clamping force. They are the perfect choice for flexible high end automation solutions. They are also ideal for further operations such as assembly, quality control or palletising of the parts in boxes.
