Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
248 words
An automatic winding machine for winding a wire-like object such as an electric wire around a drum portion of a bobbin in multiple closely packed layers, which comprises: a wire-like object position detecting means; a first synchronizing mechanism attached to said detecting means; at least one hold-down contacting element connected with said position detecting means which is positioned above said drum portion of said bobbin; means for reciprocating said position detecting means in parallel with the axis of said bobbin on a first traverse shaft extending in parallel with the axis of said bobbin, wherein said contacting elements hold-down the wire-like object against a surface of said drum portion of said bobbin in the position of the wire-like object which is about to be wound around said drum portion; traverser means reciprocably mounted on a second traverse shaft extending in parallel with the axis of said bobbin and connected with said first traverse shaft through which said wire-like object is fed and a second synchronizing mechanism connected with said traverser means for moving said traverser means in synchronism with said wire-like object position detecting means; wherein said first synchronizing mechanism allows for movement of said wire-like object position detecting means in synchronism with said traverser means; and lifting means connected to said wire-like object position detecting means and said traverser means for ascending and descending said wire-like object position detecting means and said traverser means in a vertical direction which is perpendicular to the axis of said bobbin.
Claim 2
Dependent Claim
248 words
An automatic winding machine for winding a wire-like object such as an electric wire around a drum portion of a bobbin in multiple closely packed layers, which comprises: a wire-like object position detecting means; a first synchronizing mechanism attached to said detecting means; at least one hold-down contacting element connected with said position detecting means which is positioned above said drum portion of said bobbin; means for reciprocating said position detecting means in parallel with the axis of said bobbin on a first traverse shaft extending in parallel with the axis of said bobbin, wherein said contacting elements hold-down the wire-like object against a surface of said drum portion of said bobbin in the position of the wire-like object which is about to be wound around said drum portion; traverser means reciprocably mounted on a second traverse shaft extending in parallel with the axis of said bobbin and connected with said first traverse shaft through which said wire-like object is fed and a second synchronizing mechanism connected with said traverser means for moving said traverser means in synchronism with said wire-like object position detecting means; wherein said first synchronizing mechanism allows for movement of said wire-like object position detecting means in synchronism with said traverser means; and lifting means connected to said wire-like object position detecting means and said traverser means for ascending and descending said wire-like object position detecting means and said traverser means in a vertical direction which is perpendicular to the axis of said bobbin.
