Description

Aug. 28, 1956 E. 'r. LORlG STRIP HANDLING APPARATUS 3 Sheets-Sheet 1 Filed Dec. 14, 1950 INVENTOR. EDwmT. Lowe 28, 1956 E. T. LORIG 2,760,544
STRIP HANDLING APPARATUS Filed Dec. 14, 1950 3 Sheets-Sheet 3 INVENTOR. E-owm'l. Loans BY A United States Patent STRIP HANDLING APPARATUS Edwin T. Lorig, Ross Township, assiguor to United States Steel tion of New Jersey Allegheny County, Pa., Corporation, a corpora- This invention relates to strip handling apparatus and more particularly to apparatus for coiling and uncoiling steel strip. Strip in coiled form is sometimes supported in a cradle formed by rolls and fed to processing apparatus by pulling it from the cradle rolls. There is a tendency for the coil to move axially as the strip is unwound. In order to prevent this movement side guides are necessary. These guides are expensive and cause damage to the edges of the strip. It has also been attempted to coil the strip in such a cradle, but such coiling has not been satisfactory because of the necessity of bending the strip and keeping the edges thereof substantially perpendicular to the axis of the coil.
It is therefore an object of my invention to provide an uncoiler of the cradle type in which the coil is maintained in centered position on the cradle rolls.
Another object is to provide a coiling apparatus of the cradle type in which the strip is automatically bent into coil form with the edges thereof being maintained substantially perpendicular to the axis of the coil.
A further object is to provide apparatus for bending a strip while maintaining the edges thereof in a constant plane.
These and other objects will be more apparent after referring to the following specification and attached drawings, in which:
Figure 1 is a schematic end elevation of a coil of strip mounted on cradle rolls;
Figure 2 is an enlarged view, partly in section, taken on the line IIII of Figure 1;
Figure 3 is a view similar to Figure 1 but showing the cradle rolls in conjunction with bending rolls for forming strip into a coil; and
Figure 4 is a view similar to Figures 1 and 3, but showing the coil mounted on different types of cradle rolls.
Referring more particularly to Figures 1 and 2 of the drawings, the reference numerals 2.. and 4 show cradle rolls for supporting a coil C of strip S which is to be unwound. The rolls 2 and 4 are self-centering rolls of the general type disclosed in my copending application, Serial No. 97,218, filed June 4, 1949, now Patent No. 2,593,157, dated April 15, 1952. A deflector roll 6 is mounted above rolls 2 and 4 to one side thereof. An idler restraining roll 8 is mounted below the roll 6. As shown in Figure 2, each of the rolls 2 and 4 consists of a pair of opposed frusto-conical rolls 10 which are arranged at an angle to one another with their axes of rotation intersecting at a point A between the rolls. The axes of the frusto-conical rolls 10 in each of the cradle rolls 4 are also arranged to diverge away from the direction of strip approach to the roll. In Figure 1 this movement is from the left as indicated by the arrow so that the rolls 2 and 4 have the centers of their small ends to the right of a plane extending through the centers of the large ends of the rolls and the line of contact of the coil C on the respective rolls. The large diameter ends of the rolls 10 face each other and are provided with substantially hemispherical openings 12 therein. A spherical ball 14 is provided in the openings 12 to assist in maintaining the rolls 10 on center and in alignment while the rolls are being rotated. The ball is not necessary if the rolls 10 are made sufiiciently rigid to maintain them in alignment. Lubricating grooves 16 are provided in the bottom of the hemispherical openings 12. In order to drive the rolls in synchronism bevelled gear teeth 18 are provided in the large diameter ends of the rolls 10. The outer ends of rolls 2 and 4 are rigidly supported in any suitable manner such as disclosed in my above identified patent.
In operation, the strip S is drawn from the coil C over the deflector roll 6. The rolls 2 and 4 will keep the coil C in centered position as it is unwound so that side guides are not necessary. As the coil C becomes expended it will drop deeper into the cradle formed by the rolls 2 and 4 but at no time will the coil drop to a point where the axes of the frusto-conical rolls 10 of each of the cradle rolls 4 will not diverge away from the direction of strip approach to the rolls. The point of contact of the coil C on cradle roll 2 will get further and further to the left as the coil becomes smaller. When the coil C is almost completely depleted it will sometimes pull out of the cradle and in these instances it is restrained from tending to Wrap around the roll 6 by means of the restraining roll 8.
Figure 3 shows the cradle rolls 2 and 4 used in conjunction with straightening rolls 20, 22 and 24 to act as a coiler. The strip is fed to the straightening rolls 20, 22 and 24 by means of pinch rolls 26. In this embodiment the cradle rolls 2 and 4 are arranged in the same manner as Figure 1. The straightening rolls 20, 22 and 24 are arranged beneath and adjacent the cradle roll 2 with the roll 22 being arranged to deflect the strip S downwardly from its path of travel between the rolls 20 and 24. The rolls 20, 22 and 24 are of the same type as rolls 2 and 4. The axes of the frusto-conical rolls making up the rolls 20, 22 and 24 are arranged to diverge away from the direction of strip approach to the respective rolls. The outer ends of rolls 20, 22 and 24 are rigidly supported in any suitable manner such as disclosed in my above identified patent. As the strip passes between the rolls 20, 22 and 24 it is bent in a generally circular pattern as shown by broken lines in Figure 3. By using the automatic centering rolls 20, 22 and 24 to bend the strip, the edges of the bent strip remain in the same plane as the edge of the strip before bending. As the coil builds up the edges of the strip therein will remain in a plane substantially perpendicular to the axis of the coil formed.
Figure 4 shows a different arrangement of cradle rolls. which may be used in place of the cradle rolls. 2 and 4. in the embodiments of either Figures 1 or 3. In this embodiment an automatic centering roll 28 of the type disclosed in my copending applications, Serial No. 138,389, filed January 13, 1950, now Patent No. 2,592,581, dated April 15, 1952, and Serial No. 145,648, filed February 23, 1950, now Patent No. 2,593,158, dated April 15, 1952, is substituted for roll 2 and a crown roll 30 is substituted for the roll 4. The axes of the rolls 23 and 30 are arranged parallel to each other and to the axis of the coil C supported on the cradle rolls. This apparatus will function in the same manner as that of Figures 1 to 3.
While several embodiments of my invention have 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.
