Automatic winding machine for wire-like object

Abstract

An automatic winding machine for winding a wire-like object such as an electric wire on a drum portion of a bobbin in multiple closely packed layers. The automatic winding machine includes a position detecting member for automatically detecting the position of a wire-like object which is about to be wound around the drum portion of a bobbin, and a traverser member for the wire-like object while both the position detecting member and traverser member may operate in synchronism with each other, with the result that the winding of the wire-like object around a drum portion of a bobbin may be achieved extremely accurately over the entire width of the drum portion, with freedom from the danger of lap or irregular winding. In addition, the position detecting member is provided with hold-down contacting elements which are adapted to hold down the wire-like object upon completion of the traversing of the traverser member in one direction according to the accurate detection of detecting members, thus ensuring automatic traversing movement of the traverser member with the accompanying freedom from danger of contacting elements being disengaged from the wire-like object inadvertently. In addition, the position detecting member is lifted a distance from the wire-like object, which distance is equal to the diameter of the wire-like object, due to the detecting members, such as limit switches or the like, when the position detecting members approach a flange of the bobbin. As a result, the winding of the wire-like object for the next upper layer may be accomplished smoothly.
