Interlink with buffer and sorter for the production of cast parts
Problem definition
Two machining stations in a production process for cast parts need to be interlinked. The upstream and downstream machines have different cycle times. The interlink needs to restore the system’s autonomy. Two different types are produced on the line simultaneously. They are placed on the interlink in no particular order. They must be presented to the subsequent machine sorted and with a cycle time of about 30 seconds per part. The cast parts are washed and have sharp edges. They need to lie directly on the conveying medium so that a separate workpiece carrier is not required. The system must run reliably in three-shift operation.
mk Solution
Transport system consisting of ZRF-P 2040 dual-line timing belt conveyors arranged atop one another. The timing belts have a cut-resistant coating on the transport side. Side rails prevent the parts from falling. The timing belt conveyors are each about 8 metres in length and serve as buffer lines. The system can store a total of 50 workpieces. A distributor shuttle sorts the workpieces by type onto two additional ZRF-P 2040 timing belt conveyors. A shift register ensures that the different types are correctly assigned. The distributor shuttle is a three-axis unit consisting of a lift and a traversing unit to which a timing belt conveyor is mounted. The lift is built from an LZR 2005 linear module with a stroke of about 1100 mm. It is driven by a motor with a brake. The traversing unit is also built from a linear module, with a horizontal stroke of about 640 mm. The ZRF-P 2010 timing belt conveyor provides movement along the Z-axis.
