SHEET MILL Filed May 12, 1925 //VVENT0/? f w WQW Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE JOHN B. TYTUS,- OF MIDDLETOWN, OHIO, ASSIGNOR TO THE AMERICAN ROLLING MILL COMPANY, OF MIDDLETOWN, OHIO, A CORPORATION OF OHIO SHEET MILL Application filed May 12, 1925. Serial No. 29,827.
Y My invention relates to devices for supplying the leveling operation in sheet and light plate mills, and involves the use of a series of piles of sheets.
The operation of passing sheets through a roller leveler is a slow one, and thus will form an accumulating point in a process which finishes sheets and plates in a continuous manner. A hastening of the leveling operation will give improper results, and thus without some special arrangements, the entire production would be held up at the point of leveling. Also the roller leveler works better on definite thicknesses of piece and on thin sheets its action is enhanced by doubling or matching the piece. I
Among other things, it is my object to provide a simple means of piling sheets upon each other prior to the leveling operation and leveling more than one sheet.at a time, thus raising the production of the leveler without increasing its speed. It is also my object to provide a simple mechanism in connection with a leveler for feeding piles of sheets thereto, and for receiving the sheets as rapidly as they come through the preceding processes in the rolling mill and leveling all of them without retarding the incoming speed of the sheets.
-mechanism and the like, as these may be of an familiar or desired type, and are not invo ved in my invention.
The rolls 1, 1, are typical of any setof rolls in a feed table for sheet or plate metal. At the end of the feed table, formed by the rolls,
1, or using some other form of conveyor are a pair of pinch rolls 2, 2., which take the sheets as they come along the table, and give them a :pkepdy pull and project them onto the second This second table is a horizontal one designed to catch the sheets and hold them, and to be driven when it is desired to feed away a pile of sheets which have accumulated. In the form shown a set of rolls 3, 3, is provided, same "having any desired form of conventional drive which can be turned on and oil by the operator.
In order to catch the sheets when ejected by the pinch rolls, the rolls 3 are formed with peripheral grooves 4, in line throughout the table, in which-grooves any convenient form of bars 5 are arranged. I have shown-bars of angle iron, set with a flat portion upwardly,
in the grooves of the several rolls, thereby providing a sustaining surface to prevent sheets from feeding or falling down through the spaces between the rolls.
As the sheets are projected forward by the pinch rolls, they will fall on this table formed by the rolls 3 and bars 5, and will there accumulate in piles of the desired number. VVhen accumulated, the operator starts the rolls 3 to rotate and the pieces are fed to the leveler. Ordinarily the driving of the rolls 3will be only intermittent as controlled by the operalowered and the rolls continually driven. To illustrate such a structure the diagram of Figure 3 is referred to. Here the bars 5 are connected at the ends and rods 5 thereon depend to rows of eccentrics 5 The straps 5 on the rods 5 embrace the eccentrics. In a structure like this the operator raises and lowers the bars 5 instead of starting and stopping the rollers 3.
The roller leveler is formed of a series of staggered rolls 6, through which the sheets in a pile are/passed, these rolls bein of conventional roller leveler type and riven as in customary practice.
The 0 erator will start u the rollers 3, and feed a pile of sheets to the eveler', in order to tor. However, the bars may be raised and p keep the leveler working slowly, and effectively. He will stand beside the rolls 3, and can guide the sheets as they fall onto each other, so as to form an effective pile. The leveling operation does not require great particularity in forming the piles, as no reduct ion in thickness is made, but a mere working out of bends and crimps in the sheets.
The operation of the device will be apparent from the fore oing description without illustration of tie conventional details, as has already been pointed out.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A sheet piling device for use in connection with a mill for rolling metal sheets comprising a feed table, a pair of pinch rolls, adapted to engage sheets as they move along the table, and project them forward over a second table, and a second table located to receive the sheets as they come from the pinch rolls and located below the level of the pinch rolls, said second table being formed of rolls having means extending between rolls lengthwise of the table to form a continuous support together with the rolls for sheets dropped thereon.
2. A sheet piling devicetor usein connection with a, mill for rolling metal sheets comprising e ,feed table, a pair of pinch rolls, adapted to engage sheets as they move along the table,, and project them forward over a second table, and at second table located to receive the sheets as they come from the; pinch rolls, and located below the level of the pinch rolls, said second table being formed of rolls having means extending be tween rolls lengthwise of the table to form s. continuous support together with the rolls for sheets dropped thereon the rolls of the second table being live rolls.
3. A sheet piling device for use in connection with a mill for rolling metal sheets comprising a feed table, a pair of pinch rolls, adapted to engage sheets as they move nlon the table, and project them rapidlyv forwar over a second table, and a second table located to receive the sheetsas they come from the pinch rolls, and located below the level of the pinch rolls, said second table being formed of rolls having means extending between rolls lengthwise of the table to form continuous support together with the rolls for sheets dropped thereon, said second table being formed of a series of rolls, having peripheral grooves therein, and bars to form continuous supports lengthwise of the table, and lying within said grooves at or below the level of the tops of the rolls, for the purpose described.
piling sheets one on the other, thereby providing piled sheets to the leveler and speeding up its capacity without speeding up the constituent rollers thereof.
5. In combination a feed table, and a roller leveler for metal sheets and the like, and means intermediate the table and leveler for piling sheets one on the other, thereby providing piled sheets to the leveler and speeding up its capacity without speeding up the constituent rollers thereof, said means comprising a pair of pinch rolls adapted to project the sheets from the table to an accnmulating table, and an accumulating table edapted to be driven when desired, to feed the accumulated sheets in a pile to the roller leveler. 1
