N VIiN'I'UR. HENRY A. AGONIS This invention is directed to means for paying wire from coils as opposed to reels or spools. In the nomenclature of the trade a wire coil refers to a bundle of turns of wire that can be shipped free from any supporting reel hub or flange structure. Wire, particularly steel wire, is commonly shipped in the form of coils, to avoid the cost of reels, but upon delivery to a cable factory, is paid off of the coils and wound upon reels for use on the stranding machines. In paying off the wire it has been known to lay the coils on rotating platforms and pull the wire through a guide mounted high above the center of the platform. Where the coils are very deep, or where a plurality of coils are stacked above each other, a coil frame may be fixed to the platform to retain the coils in position. The coils are not wound over this frame, and each turn of the coil is not tight around it, but are lowered onto the platform with the frame fitting through the open cores of the coils. Although the pulling of the wire through the overhead guide may cause sufficient rotation of the platform under some circumstances, it has also been known to drive the platform to rotate at the approximate speed required for delivery of wire without introducing additional twists at the overhead guide. To adjust to variations in coil diameter the speed of rotation of the platform can be adjustable.
This known apparatus for paying of? wire from coils has the serious defect that it results in more or less frequent snarls or tight loops of wire that will not pass through the overhead guide. In addition, if the wire is pulled even momentarily faster than the platform and frame can rotate, the wire will be stretched or even break with the danger of personal injury. If a break occurs, the reel winding wire drawing, or other operation into which the coil wire is being paid, will also be interrupted.
SUMMARY l have overcome the defects of prior wire coil pay offs of the types described and invented apparatus capable of substantially complete freedom from snarls and stoppages by inventing an apparatus for paying off wire from a coil comprising rotatable means, such preferably as a platform supporting a tapered coil frame, horizontally supporting the coil, drive means, which may comprise a manual speed adjustment, rotating the supporting means around a vertical axis, and guide means for the wire mounted substantially centrally above the supporting means. Means are provided for pulling the wire through the guide means and means such as a tube surrounding a length of the wire, directing it from the coil to the guide means. My directing means is freely rotatable around a vertical axis within the coil, such as the axis of rotation of the supporting means. The means, such a central post, that rotatably supports the directing means may be mounted on the platform or other supporting means and rotate with it, or the post may be fixed to the ground and project through the supporting means while the latter rotates around it. My apparatus may advantageously also comprise means that are sensitive to the rotation of the directing means for controlling the speed of rotation ofthe supporting means.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 shows a side view of the apparatus of my invention. FIG. 2 shows a side view, partly in section of a feature of an embodiment of my invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT A coil pay-off, indicated generally by the numeral comprises a rotating platform 11 mounted on a journal 12 and driven to rotate by a motor 13 and variable speed control unit 14 with a hand wheel 16. A coil frame 17 is mounted on the platform 11 surrounding and fastened to an upright post 18. A
When it is desired to pay off coils where the turns are not all equal, but have been built up on an arbor, so that the diameters of the turns become progressively smaller as the coil pays off, my apparatus will also be useful. Similarly, where the coil being paid off is not pulled by a constant speed device such as the capstan 31 but is wound directly onto a reel so that the speed of pulling off keeps increasing. In such cases it is advantageous to vary the speed of the motor 13 or the speed control unit 14 to adjust to the progressive changes in the payoff or take-up loop diameters. l have accomplished this by means of a master-slave control 44 of conventional design wherein the master is mounted in the post 41 and senses the speed and direction of rotation of the directing unit 23 and the slave increases or decreases the speed of the platform 42 by adjusting the speed control unit 14.
