Abstract
Abstract The bobbin conveying mechanism of the instant invention is directed to a movable conveyor assembly which is operative to magnetically engage an end of a bobbin having a metal ferrule about the end thereof and move the bobbin to a position for rotatably conveying of the bobbin to, for example, a downstream orienting mechanism.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A bobbin handling apparatus comprising, magnetic means, bobbin conveying means intermediate bobbins to be conveyed and said magnetic means and movable relative to said magnetic means and adapted to hold an end of a bobbin in association with said magnetic means for conveying of said bobbin, means to move said conveying means relative to said magnetic means, means to move said magnetic means and said conveying means in a first direction between a first bobbin end pickup position to a second position for further conveying of the bobbin in a second direction transversely to said first direction, means for dislodging said bobbin from holding association with said conveying means at a predetermined position, means for sensing the absence of an additional bobbin upon the conveying means when said bobbin is urged from the conveying means and producing a signal, and means to advance said conveying means and said magnetic means to said first bobbin pickup position responsive to said signal.
Claim 2
Dependent Claim
160 words
A bobbin handling apparatus comprising, magnetic means, bobbin conveying means intermediate bobbins to be conveyed and said magnetic means and movable relative to said magnetic means and adapted to hold an end of a bobbin in association with said magnetic means for conveying of said bobbin, means to move said conveying means relative to said magnetic means, means to move said magnetic means and said conveying means in a first direction between a first bobbin end pickup position to a second position for further conveying of the bobbin in a second direction transversely to said first direction, means for dislodging said bobbin from holding association with said conveying means at a predetermined position, means for sensing the absence of an additional bobbin upon the conveying means when said bobbin is urged from the conveying means and producing a signal, and means to advance said conveying means and said magnetic means to said first bobbin pickup position responsive to said signal.
Claim 3
Dependent Claim
28 words
Apparatus in accordance with claim 1 wherein said bobbin conveying means comprises an endless conveyor positioned about said magnetic means for conveying said bobbins in said second direction.
Claim 4
Dependent Claim
38 words
Apparatus in accordance with claim 2 including means to interrupt said moving of said conveying means relative to said magnetic means when said bobbin is at said predetermined position for transfer of the bobbin from said conveying means.
Claim 5
Independent Claim
175 words
A method of conveying a bobbin comprising, advancing a bobbin having a butt end and apical end from a source of supply to a conveying means positioned for slideable relationship to means for generating a magnetic field at a first position, magnetically attracting one end of said bobbin at said first position, moving said bobbin in a first direction from said first position to a second position by moving both said conveying means and said means for generating a magnetic field and while at said second position moving said conveying means relative to said means for generating a magnetic field to further convey said bobbin in a second direction transversely to said first direction and to a predetermined position, dislodging said bobbin from said conveying means at said predetermined position, sensing the lack of an additional bobbin upon said conveying means following said dislodging and producing a signal, and advancing both said conveying means and said means for generating a magnetic field from said second position to said first position in response to said signal.
Claim 6
Independent Claim
175 words
A method of conveying a bobbin comprising, advancing a bobbin having a butt end and apical end from a source of supply to a conveying means positioned for slideable relationship to means for generating a magnetic field at a first position, magnetically attracting one end of said bobbin at said first position, moving said bobbin in a first direction from said first position to a second position by moving both said conveying means and said means for generating a magnetic field and while at said second position moving said conveying means relative to said means for generating a magnetic field to further convey said bobbin in a second direction transversely to said first direction and to a predetermined position, dislodging said bobbin from said conveying means at said predetermined position, sensing the lack of an additional bobbin upon said conveying means following said dislodging and producing a signal, and advancing both said conveying means and said means for generating a magnetic field from said second position to said first position in response to said signal.
Claim 7
Dependent Claim
44 words
A method according to claim 4 including the step of producing to signal to actuate means to advance said bobbins from said source of supply to said first position during said advancing of said conveying means from said second position to said first position.
Claim 8
Dependent Claim
46 words
A method according to claim 5 including the step of sensing an additional bobbin upon said conveying means following dislodging of said bobbin and, in response thereto, producing a signal to actuate means to advance said conveying means and thereby said additional bobbin for said dislodging.
