Abstract: 917,128. Coiling; reeling. VAUGHN MACHINERY CO. April 10, 1961 [Dec. 15, 1960], No. 12851/61. Class 83 (4). A wire packaging machine comprising a takeup block arranged to have wire coiled about it with the convolutions descending from it by gravity, a support on which to form an upwardly growing package; and a means to periodically rotate the support in opposite directions about a vertical axis off-set with respect to the axis of the convolutions whereby they are laid in circular progression on the support to form a package having a diameter greater than that of the individual convolutions and whereby successive packages are formed from a continuous length of wire by providing slack in the wire between the top of the formed package and that to be formed. A machine comprises a fixed tubular shaft 2 attached to a head 1 to which is attached sheaves 3, 4, a take-up block assembly 5 and a journalled flyer assembly 6, belt driven by a motor 10 via belts 7, 9 and a speed reducer 8. The block assembly 5 may consist of a plurality of nested blocks screwed to the shaft 2 so that one or more of the outer ones may be screwed upwardly to expose an inner one of a smaller diameter. The flyer assembly 6 comprises a sheave 11 and a pressure roller 15. The arms 17 of the head 1 support a funnel guide 16 and adjustable accumulator fingers 19. A turntable 18 comprises a centre shaft 24 driven through gearing 26 by a reversible motor 25 and a support housing 29 mounted on a horizontal pivot 30 of an adjustable member 32 supported on rollers 35 of a base member 36 fixed to a well floor 37. An arm 33 attached to the member 32 allows adjustment of the turntable axis relative to the take-up block axis and is secured in position by screws 34. The turntable is rotated one revolution in alternate directions, a reversing switch 38 attached to the housing 29 is actuated by a cam 39 attached to the turntable. A pneumatic cylinder 31 is used to rotate the turntable about the pivot 30 into a horizontal plane. A roller conveyer 20 is provided on the turntable on which a platform 21 having a coaxial core 22 is fitted. The platform 21 is prevented from slipping off the turntable in the tilted position by a fixed ring 40 which engages the lower side of the platform 21. Conveyer sections 41, 42 are provided on either side of the turntable to facilitate loading and unloading. A tray 43 is provided to hold a number of loops of wire adjacent to the changeover position. Operation.-As the flyer assembly 6 rotates a continuous length of wire W passes over the sheave 3 through the shaft 2 over the swivel sheave 11 and is wrapped around the take-up block 5 at the bevelled shoulder 14 so that the convolutions are progressively shoved upwardly until the top one clears the pressure roller 15 which holds it against the periphery of the take-up block 5. The top convolutions continuously gravitate through the funnel guide 16, over the core 22 and on to the top surface of the rotating platform 21. When the required number of turns have been accumulated the fingers 19 are rotated into the path of the wire which is then collected in the funnel guide 16 allowing for the removal of the completed coil and the replacement of an empty platform 21. Several of the top loops of wire from the formed coil are placed in a tray 43 adjacent to the machine, as the turntable rotates in opposite directions the loops become longer or smaller in diameter.
