4Claims. 1
This invention relates to apparatus for uncoiling bundles of wire and is a continuation-in-part of my copending application, Serial .No. 228,919, filed May 29, 1951. The invention is particularly suited to the uncoiling of bundles of hard drawn wire such as :rope wire and spring wire of small diameter which is to be fed to a processing machine such as a spooler. Uncoilers of this general type are in common use but all have various-disadvantages. For example, the tension applied to the wire asit is being unwound may vary and the wire :may kink orbecome snarled when the spooling mechanism is stopped. The size of coil which can be handled and the speed of the pay-off reel are limited. The Wire is generally pulled from the top of the coil or in some instancesfrom the outside surface between the top and bottom of the .coil. This in many instances results in uneven tension and kinking of the wire due to the fact that the angle of feed is constantly varying.
It is an object of my invention to provide uncoiling apparatus which can handle large coils of wire at high speeds.
This andother objects will be more apparent after referring to the following specification and attached drawings, in which:
Figure 1 is a top plan view of my. device;
Figure 2 isa vertical sectional view;
Figure 3 is a fragmentary sectional view showing a detail of-my device;
Figure 4is a fragmentary sectional view showing a further detail of my device; and
Figure 5 is a detailed view of the sheave of Figure 2.
Referring more particularly to the drawings, the reference numeral. 2 indicates the base plate of the uncoiling device. The base 12 is preferably mounted on four legs 4. Spaced angle brackets B are fastened to the underside of the base 2 for supporting a sheave or rotatable guide 8 which is mounted on shaft 10. Asbest shown in Figure 5, the rotatable guides has a wire supporting surface 8S much greater in width than the diameter of the wire and a flange 8F at each end thereof so as to form a deep wide groove. A plurality of bars l2 are fastened to and extend upwardly from the base 2 and are welded around the periphery of a hub H to form a block ii. The block I5 has a maximum diameter at its base which is greater than the inside diameter of the coil W and tapers upwardly to a minimum diameter. A hearing it is mounted in the hub 14 and is held in place by means of a plate 18. A shoulder 20 is provided at the top of the hub H for a purpose which will be explained later.
A central-opening 22 is arrangedin the plate 2 directly beneath the openingin the bearing 16 and substantially in line with the sup-porting surface of the sheave 8. A U-shaped tubular guide 24 has one leg passing through these aligned openings with its lower-end extending for a short distance through the plate. A collar 26 is fastened to this leg and bears .against the top of bearing I6, thus holding the U-shaped member in position. The other leg extends downwardly on the outside of the block [5 to a point adjacent the bottom of the coil W. A tungsten carbide guide 28 is preferably mounted in the lower end of the U-shaped member. A standard take-off mechanism 30 maybe provided adjacent the machine for pulling the wire from the uncoiling device. In someinstances the processing machine itself will act to pull the Wire from the block 15.
The operation of the device is as follows:
The U-shaped member 24 is removed by pulling it upwardly out of the opening in the bearing l6 and a coil of wire W is placed on the reel and its ends freed. A hold-down ring or plate 32 is then placed on top of the coil W around the reel,
a after which the starting end ofJthe coil is threaded from the bottom of the coil through the tungsten carbide guide 28 and through both legs of the U-shaped member 24. The ring 32 may be provided with lugs which engage the bars H. to prevent rotary movement of the ring. The U-shaped member 24 is placed in position through the bearing l6 and hole 22 as shown. The wire is pulled around the sheave 8 to the take-up mechanism 30 from whence it is taken to the processing equipment suchas a spooler (not shown).
It will be seen that the coil of wire W has a smaller inside diameter than the diameter at the bottom of the block l5 so that wire will not rest upon thedbase 2 but will be supported by the block l5 a short di'stanceabove the base. The entrance end of the tubular guide 24 is approximately at the same level as the bottom of the coil. The hold-down ring 32 acts as an automatic feed device "by keeping the lower convolutions of the bundle or coilW tight against the tapered side of the block and continuously forcing the coil downwardly as it "is unwound. The
wire is always fed to the entering orifice of U- shaped member 24 substantially at right angles thereto. In other words the wire is always being payed off at substantially the same point and at the same uncoiling diameter and speed and since the rotating speed of the tubular guide 24 is constant the tension on the wire is substantially uniform.
When a coil has run out the take-off mechanism is stopped with the last few convolutions of wire projecting from the feed end of the guide 24. The guide 24 and hold-down ring 23 are removed after which a new coil is loaded on the block 15 and the tubular guide 24 and hold-down ring 32 replaced. The end of the first wire is then welded to the end of the new coil and the feeding of the wire to the processing equipment is resumed.
Forlarger coils of wire a reel block 34 of larger diameter having a hub shaped to fit over the hub 14 and rest on the shoulder 20 may be provided as shown in Figure 3. Holes may be provided in the plate 2 to receive the lower part of the rods making up the block and thus prevent rotation thereof. For still larger coils an additional reel block 36 is placed over block 34 as shown in Figure 4.
While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
