Abstract
Abstract A winding machine including a wire laying means, a reel on which the wire is wound, a motor for driving the wire laying means, and means for reversing the driving motor. The improvement comprises means for controlling the reversal of the wire laying means including means for sensing the ends of the reel and generating an output signal indicative thereof; means coupled to the sensing means and the motor reversing means, and responsive to the output signal generated by the sensing means, for transmitting the generated signal to the motor reversing means after a predetermined delay period; means for sensing non-uniform distribution of the wire at the ends of the reel and generating a second output signal indicative thereof; means coupled to the first output signal transmitting means and responsive to the second output signal generated for adjusting the predetermined delay period; and means coupled to the first output signal transmitting means for gradually restoring the signal delay period to the predetermined delay period.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
In a winding machine including a wire laying means, a reel on which the wire is wound, a motor for driving the wire laying means, and means for reversing the driving motor, means for controlling the reversal of the wire laying means, comprising: means for sensing the ends of said reel and generating a first output signal indicative thereof; means, coupled to said sensing means and said motor reversing means, and responsive to said output signal, for transmitting said signal to said motor reversing means after a predetermined delay period; means for sensing non-uniform distribution of the wire at the ends of said reel and generating a second output signal indicative thereof; means, coupled to said first output signal transmitting means and responsive to said second output signal, for adjusting said predetermined delay period; and means, coupled to said first output signal transmitting means, for gradually restoring the signal delay period to said predetermined delay period.
Claim 2
Dependent Claim
156 words
In a winding machine including a wire laying means, a reel on which the wire is wound, a motor for driving the wire laying means, and means for reversing the driving motor, means for controlling the reversal of the wire laying means, comprising: means for sensing the ends of said reel and generating a first output signal indicative thereof; means, coupled to said sensing means and said motor reversing means, and responsive to said output signal, for transmitting said signal to said motor reversing means after a predetermined delay period; means for sensing non-uniform distribution of the wire at the ends of said reel and generating a second output signal indicative thereof; means, coupled to said first output signal transmitting means and responsive to said second output signal, for adjusting said predetermined delay period; and means, coupled to said first output signal transmitting means, for gradually restoring the signal delay period to said predetermined delay period.
Claim 3
Dependent Claim
39 words
The invention according to claim 1, wherein said reel comprises a central core and two end flanges, and wherein said means for sensing the ends of said reel comprise light gates arranged to intersect the flanges of said reel.
Claim 4
Dependent Claim
60 words
The invention according to claim 2 wherein a pivotable roller is installed ahead of the laying device in engagement with the wire, and said means for sensing non-uniform wire distribution comprises means for sensing the velocity of pivotal motion of said feeler roller and means for adjusting said predetermined delay period when said feeler roller velocity exceeds a predetermined value.
Claim 5
Dependent Claim
15 words
The invention according to claim 1 wherein said driving motor comprises an electric stepping motor.
Claim 6
Independent Claim
114 words
A method of controlling the reversal of direction of a wire laying means driven by a motor, which winds the wire on a reel in a winding machine, comprising the steps of: moving the wire laying means to distribute wire on the reel; sensing the point at which the ends of the reel are reached by said wire laying means; reversing the direction of the wire laying means a predetermined delay time after said reel ends are sensed; sensing the uniformity of distribution of the wire wound on the reel; adjusting said delay time when non-uniform wire distribution on said reel is sensed; and gradually restoring said delay time to said predetermined delay time.
Claim 7
Independent Claim
