At the moment We have 4 selectives soldering machines ( Ersa ) and at each one We have dedicated 1 operator per shift doing only the activity to return the empty pallets in a transporting car from the Unload station ( after AOI ) to the Load station ( before Selective solder process ). A distance of around 12 meters every 8 pallets.This mean 4 Selectives Soldering machines running 3 shifts per week, this give Us a total of 12 operators ( 3 per machine) doing this activity . Now with this conveyors these resources will be removed from the actual personal staff required for selective solder machines. We already tried a gravity conveyor but due to the distance, it was not possible and also this gravity conveyor interrupt the machine maintenance space ( placed next to the machine ) and the automatic conveyors will be installed beyond the machine
