Claims. (Cl. 2663) This invention relates to a reeling apparatus and more particularly to a pouring reel apparatus for coiling steel rod as it leaves the last stand of a rolling mill.

In the production of steel rod, it is the usual practice to form the rod into coils after it leaves the rolling mill in order that it may be handled more easily. It is important to lower the temperature of the rodbelow the critical temperature of the steel within ashort time after it leaves the rolling mill. Otherwise, scale forms rapidly on the surface of the rod and it may be diflicult to obtain desired metallurgical properties. Although the rod is passed through water boxes between the mill and the reel, the time in which it resides in the boxes and is cooled thereby is very short. As a matter of fact, the increases in rolling speed that have taken place recently have made this method of cooling less and less effective. If cooling is not begun until the coil is removed from the reel, the rod has the entire cooling time in which to deteriorate. It has been suggested in the patent to Myles Morgan No. 2,621,914 that the cooling of the rod take place in the reel itself and that patent shows a laying reel which provides for such cooling. Difliculties have been experienced in carrying out this concept with a pouring reel and the present invention obviates these difliculties.

It is therefore an outstanding object of the present invention to provide a reeling apparatus in which hot rod may be quickly cooled during the reeling operation.

Another object of the invention is the provision of a pouring reel having apparatus for cooling rod during the coiling operation without interfering with the normal operation of the reel.

With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended hereto.

The character of the invention, however, may be best understood by reference to certain of its structural forms, as illustrated by the accompanying drawings in which:

Figure 1 is an elevational view of a reeling apparatus embodying the principles of the present invention,

Figure 2 is an elevational view of the invention taken along the line 1I-II of Figure 1,

Figure 3 is a horizontal sectional view of the invention taken on line IIIIII of Figure 3, and

Figure 4 is a Vertical sectional view of the invention taken on the line IVIV of Figure 3.

Like reference characters denote similar parts in the several figures of the drawings.

Referring first to Figure 1, wherein are shown the overall aspects of the invention, the reeling apparatus, indicated generally by the reference numeral 10, is shown as comprising a pouring reel 11 having a superstructure 12 mounted thereover. A push-off mechanism 13 is situated to one side of the reel 11 and a conveyor 14 at the other side. A coil discharging mechanism 15 is operatively connected to the reel for ejecting the finished coil. A cover 16 rests on the upper edge of the housing 17 of the reel 11 and a lower section 18 of a conduit 19 is mounted centrally thereof and extends therethrough. The

upper section 20 of the conduit 19 is dependent from a table portion 21 of the superstructure 12. A fan 22 is mounted on the upper side of the table portion 21 and discharges into the upper end of the upper portion 20 of'the conduit 19. Electric motors 23 and 24 are operatively connected to drive the fan. The table portion 21 is mounted on vertical legs 25 which may be structural beams and attached to these legs is an intermediate table 26 on which is mounted an electric motor 27. This motor 'is connected to adjacent sprocket wheels 28 and 29 around which is fed a sprocket chain 30. One end of the chain 30 is fastened to the table 26 by a pin 31, while the remainder of the chain leaves the wheels 28 and 29 and passes over the idler wheel 32 before being. attached to the cover 16. The upper and lower portions 18 and 20 of the conduit 19 telescope with'one another and .a suitable air-tight seal 33 is provided therebetween.

Figure 2 shows the invention from another aspect and on a slightly larger scale. In this view it can be seen that the sprocket chain 30 is duplicated on either side ofthe conduit 19, as is the idler pulley 32. This view in conjunction with Figure 3 shows particularly well the manner in which airfrom the conduit 19 is caused to flow through the coil and is removed. The lower portion 18 of the conduit extends downwardly into the reel to within a short distance of the bottom and defined by a coil plate, as shown in Figure 4. A conical diffuser 34 is mounted axially of the lower end and serves to cause the air to flow radially outwardly. The cover 16 consists of a generally spherical central dome 35 which fits over the housing 17 of the reel and abutment portions 36 and 37 which extend outwardly therefrom. The abutment portions overlie and act as covers for open-topped pock'ets38 and '39, respectively, which are formed integrally with the housing of the reel. These pockets connect at one side of the reel to a conduit 40 Which is suitably connected to :lead used or warm air away from the apparatus. A suitable recess '41 is provided in the area of connection of the pockets 38 and 39 to the conduit 40 to receive a pulley 42 which carries the pushed rod 43.

In Figure 4, which is a sectional view, some of the details of the reel 11 can 'be seen. A circular series of inner pins 44 and a similar series of outer pins 45 are fastened at their lower ends to a drive plate 46 which in turn is driven through gearing contained in the lower portion 47 of the reel. A coil plate 48 is freely slidab'le along the pins under the action of the coil-discharge mechanism 15 from a position adjacent the drive plate .46 to .a position in which its upper surfaceis on a level with the upper edge of the housing 17 of the reel and on a level with the conveyor 14, a pouring pipe 49' enters the housing of the reel for the admission of rod between the series-of pins.

The operation of the apparatus willnow be understood in view of the above description. The rod leaves the finishing stands of the rolling mill and, after passing through water boxes, enters the reel 11 through the rod pipe 49. Thenrod enters the annular space between the series of pins 44 and 45 and is formed into a coil by the rotation of the drive plate 46, the coil plate 48 and the pins. At the time that the rod enters the reel, the cover 16 is tightly in place on top of the housing 1.7 of the reel. The motors 23 and 24 are driving the fan 22, so that a stream of air is forced down the conduit 19 and strikes the diffuser 34. The diffuser causes the air to flow outwardly in a generally horizontal direction through the coil of rod which is being formed. The air also passes upwardly around the outer surface of the lower end of the conduit. In any case, theair flows outwardly and upwardly, eventually striking the dome 35 of the coveu. The air then flows outwardly in the abutmeat portions 36 and 37 and is directed downwardly into the pockets 38 and $9. The air then flows rearwardly in the pockets and into the conduit 40 within which it flows to a stack or other disposal means, not shown. After the coil of rod is completed, the mechanism is set in motion, thus raising the coil plate 48 and the coil above the upper edge of the reel housing; at the same time the motor 27 is actuated, thus setting the sprocket wheels 28 and 3.9 in motion and drawing the chains 39 upwardly over the idler wheels 32. This moves the cover 16 upwardly and the lower portion 18 of the conduit 19 with it. The portion 18 moves upwardly in telescoping relation to the upper portion 20 of the conduit. The cover 16 and the conduit are moved upwardly to a height sufiicient to clear the coil when it is in its uppermost position. When coil and cover are raised sufficiently high, the mechanism 13 is set in motion, thus actuating the pusher rod 43 to push the coil onto the conveyor 14. Upon the removal of the coil and the retraction of the pusher rod, the cover is lowered into place again and the apparatus is ready to receive another rod length.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, however, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.
