Abstract
Abstract A CLOSED AUTOMATIC SYSTEM FOR HANDLING BOBBINS FOR PREVENTING THE SYSTEM FROM BECOMING LOADED WITH BOBBINS WHICH CANNOT BE EFFECTIVELY HANDLED WITHIN THE SYSTEM. FILLED BOBBINS ARE CONVEYED, AS NEEDED, FROM A SUPPLY AREA TO A WINDING AREA WHERE THE BOBBINS ARE PREPARED FOR UNWINDING ON A SELF-TENDING WINDER. BOBBINS EJECTED FROM THE WINDER AUTOMATICALLY SORTED AND THE SUBSTANTIALLY EMPTIED BOBBINS ARE RETURNED TO THE SUPPLY AREA. PARTIALLY FILLED BOBBINS EJECTED FROM THE WINDER ARE RETURNED TO BE AGAIN PREPARED ALONG WITH OTHER FILLED BOBBINS, FOR RETURN TO THE WINDER. HOOWEVER, SOME OF THE FILLED BOBBINS MAY, FOR VARIOUS REASONS, BE IN SUCH CONDITION THAT THEY CANNOT BE PREPARED FOR UNWINDING OR HAVE NOT BEEN PROPERLY PREPARED FOR USE BY THE WINDER. IN ORDER TO KEEP THE SYSTEM FROOM BECOMING LOADED WITH SUCH DEFECTIVE BOBBINS, THE BOBBINS ARE INSPECTED AND BOBBINS NOT PASSING INSPECTION ARE REJECTED FROM THE SYSTEM, AND ARE DEPOSITED OUTSIDE OF THE SYSTEM FOR SUBSEQUENT MANUAL INSPECTION.
