WINDING MACHINE Filed April 25, 1931 2 Sheets-Sheet 2 Patented Oct. 30, 1934 PATENT OFFICE f INGMLACHINE A George W. Kierspe, Fort Wayne, 1nd., assignor to .isinvention; r atestoecoilwindme ma h es uohnforexamplerasi hose empl y d in winding a plurality of paper separated coils of wire upon cores of various cross sections which are generally 63 35 formed of cardboard or some similar material. The cores are of suificient length to permit a plurality of spaced coils to be simultaneously wound thereon and the machines are usually provided with a gang of cutters movable to and from the winding spindle to cut the paper insertions between the individual coils of wire. The knife blades for this purpose are necessarily of light weight material which is well suited for cutting the thin paper inserts, but which is not 2 1'; adapted to withstand the hard usage occasioned in cutting through the core material. In using such light weight knives, such as razor blades, for cutting the core material, the edges are quickly blunted and the cutting operation is relatively ,539 slow, but when used merely for cutting the thin paper inserts the blades are satisfactory and last for extended periods.
An object of this invention is to provide a coil winding machine of the type set forth with an {ijrggimproved construction and arrangement of core cutting mechanism.
This and other objects which will be apparent to those skilled in this particular art are accomplished by means of the invention illustrated in the accompanying drawings in which,
Fig. 1 is a perspective view of a part of a winding machine provided with a cutting mechanism constructed in accordance with one embodiment of this invention.
r335 Fig. 2 is a transverse sectional view through a part of the machine illustrated in Fig. 1 showing the operation of cutting a coil supporting core, and
Fig. 3 is a similar view showing a different 3gp position of the parts.
The embodiment of the present invention which has been chosen for the purposes of illustration is shown in connection with a coil winding machine having a spindle 5 adapted to be rotated by 5a suitable motor 6 to wind a plurality of coils '7 of wire 8 supplied to the spindle over the usual wire guides 9 from the usual supply spools (not shown). The spindle 5 is adapted to receive and support a coil forming core 10 of cardboard or ,550 some similar suitable material and the core may be of various cross sections such as the square core illustrated in the drawings. The coils '7 are wound in the usual way and sheet material 11 from a suitable source of supply 12 is delivered to the spindle and wound thereon between the General'Cable Corporation, New York, N. Y., a corporation of New Jersey Application April 25,1931... Serial No. 532,794 I ':='-3Claiin's. (01.164-69) separate layers of wire to form the usual paper inserts, the sheet material 11 being of sufficient width to extend the entire length of the spindle 5. Pap r cutting knives 13 are mounted upon suitable movable supporting arms 14 so that such knives can be moved toward the spindle for the purpose of cutting the paper inserts between the individual coils, in the usual way.
As above described the most satisfactory knives for cutting these paper inserts are of light weight material and are not suited for rapid or eflicient cutting of the heavy core material 10. For the purpose of enabling the rapid cutting of this core material, the present invention contemplates the provision of a second gang of knives which are sufficiently heavy to permit rapid severing of the core 10 along lines coinciding with the planes of operation of the paper knives 13. As illustrated, the core cutting knives include a plurality of holders 15 provided with relatively heavy cutting blades 16 and adjustably positioned upon a supporting cutter bar 17 which is supported at each end upon spaced, vertically movable, threaded supporting rods 18, each of which is threaded to a rod shifting nut 19 connected by gearing 20 to a cross shaft 21 connected to an operating gear 22 adapted to be rotated by a suitable handwheel 23 placed in an accessible position at the front of the machine. A cutter guard comprising a frame 24 mounted on d supporting pivots 25 is drawn by a spring 26 to the inoperative position shown in Fig. 2, a suitable stop 27 being provided to limit the movement of the guard frame 24 by the spring 26. The frame is so positioned that its lower edge is engaged by the lower corners of the cutter holders 15 when the latter are retracted so as to move the cutter guard against the tension of the spring 26 into covering position over the cutter blades 16, when the latter are inoperative as shown in a Fig. 3.
In operation, when the operator desires to sever the core 10, he raises the gang of cutters by suitable rotation of the handwheel 23. The upward movement of the cutter holders 15 permits the 109 guard frame 24 to be drawn away from the cutters by the spring 26, and the cutters continue to move upwardly until in cutting position. The arrangement is such that the cutters can be forced into the material of the core 10 with suitable pressure, and the cutter blades 16 being of sufficiently heavy material the core is rapidly and accurately severed, after which the cutters are retracted to the inoperative position shown in Fig. 3. The provision of this form of core cutting mechathe spirit of this invention or the scope of the appended claims.
I claim as my invention:- g V 1. The combination in a winding machine of a winding spindle adapted to support a tubular core for wire coils, means, for rotating said spindle, a cutter bar, a gang of tube cutting blades,
mounted on said bar, a support for moving said bar toward and from said spindle, a pivoted cutter guard and means for supporting said guard so that retraction of said cutter bar from said spindle moves said guard into blade covering position.
2. The combination in a winding machine of a winding spindle adapted to support a tubular core for wire coils, means for rotating said spindle, a cutter bar, cutting knives supported on said bar, a threaded support for said cutter bar, a geared drive associated with said support for raising and lowering said cutter bar toward and from said spindle and a pivoted blade cover operated upon retraction of said bar to cover said blades when in non-cutting position.
3. The combination in a winding machine of a winding spindle adapted to support a core for wire coils, means for rotating said spindle so as to wind coils on said coil, a sheet material supply for delivering sheet-material to be wound on said spindle, a cutter for severing said sheet material,
a second cutter adapted to extend through the slot formed by said first cutter in said sheet material and engage said core, and means for forcing said second cutteragainst said core under pressure and for retracting said cutter therefrom.
