Handling engineering from AMI

Pack and stackDestacker, 1st procedureWherever containers, boxes, pans,workpiece carriers or trays have to bestored temporarily and made quicklyavailable again when required, thestackers and destackers from AMI arebeing used.For the stacking functions, two proceduresare available. In the 1st procedure,the container stack is moved up anddown in each cycle. The containers,boxes, etc. that are fed individually arestacked by placing them inside oneanother. This is how it works: Theempty container is fed to the automaticstacker by a belt conveyor, picked upby the gripper unit and lifted. The subsequentsecond container is positionedbelow the lifted one, which is loweredand placed in the second one. The containerstack is then lifted again, and thenext container positioned below it. Thisprocess is repeated until a completecontainer stack has been formed.In the 2nd method, the stack is formedas follows: Here, too, the first containerenters the stacker unit, is lifted andtransferred to a second fixed grippersystem. The subsequent second containeris positioned below the lifted one,lifted by the moving gripper systemand then slid from below into the firstcontainer. The fixed gripper systembriefly opens and then grips the secondcontainer. This process, too, is continueduntil stack formation is complete.Finally, the container stack is grippedby the moving gripper system anddeposited on the belt conveyor. Duringdestacking, the procedures take place inreverse order.

Always on the moveCustomized SolutionsThis twin-axis handling system from AMIfeatures a combination of motorizedswivel and lifting axes for transferringworkpieces. The mechanical interfaceof this solution is a moving table ontowhich individually adapted gripperunits can be mounted. This handlingunit is delivered ready-to-connecttogether with the sensors required forcontrol and the energy supplies andend position buffers.The highly dynamic axis combinationof the AMI shuttle traverses workpiececarriers under a welding robot. In thisparticular application, each split secondis important for the change of theworkpiece carrier. The 11-kW horizontalaxis moves a mass of more than1,000 kg within a second over adistance of 1 m. This is done by a servomotor at a repetitive accuracy of lessthan +/- 0.3 mm. The lifting axis stillachieves a distance of 80 mm in0.5 seconds. Given the geometricalsituation, four eccentric drives havebeen synchronized by means of shaftsand connecting rods. The drive consistsof a converter-operated braking motor.Twin-axis handling systemShuttleAMI Förder- und Lagertechnik GmbHAm Wehrholz · D-57642 AlpenrodPhone +49 (0) 2662.9565-0 · Fax +49 (0) 2662.939775www.ami-foerdertechnik.de · info@ami-foerdertechnik.de
