GRIGER Kai Jm United States Patent Cfiice 3,049,314 Patented Aug. 14, 1962 3,049,314 COIL HANDLING DEVICE Glenn M. Criger, Riverside, Calif., assignor to Aluminum Research Corporation, a corporation of Delaware Filed Oct. 21, 1960, Ser. No. 64,109 4 Claims. (Cl. 24279) This application relates to winding and reeling and relates, in particular, to winding and reeling sheet material.
As i well known in the art, the advance of sheet material, such as sheet metal, from a supply reel, mounted in a supply stand, through a process machine to a take-up reel rotatably mounted in a take-up stand on the opposite side of the machine involves constant removal of empty reels from the supply stand and the subsequent introduction of empty reels in the take-up stand as coils of material are advanced through the machine.
It is further Well known in the art that near the takeup stand, there is usually available a device known as a wrapper, a typical embodiment of which is shown in US. Patent 2,345,756, utilized to partially encircle an empty take-up reel to facilitate starting a leading edge of material about the empty reel.
As soon as several layers or convolutions are established upon the take-up reel, the wrapper is removed and returned to its rest position awaiting use upon introduction of the next empty reel in the take-up stand.
In prior art devices the wrapper or its equivalent is invariably an instrumentality independent from the device utilized to convey and insert an empty reel in the take-up stand. Thus, the wrapper is utilized only after the empty supply reel has been mounted in the supply stand ready for receiving sheet material.
Although the wrapper device disclosed in the exemplary embodiment of the invention is a belt wrapper, it is not intended that the practice of the invention be so limited recognizing that any wrapper device which partially encircles the reel will produce the desired result.
The present invention contemplates a process or method of handling sheet material passing from a supply reel to a take-up reel wherein the wrapper device has at least a dual function, namely, 1) serving in the conventional fashion to facilitate the Winding of the initial several turns on the empty reel and (2) utilization as a material handling device for receiving and conveying an empty reel to the take-up stand.
Therefore, a particular feature of the present invention is the provision of a winding and reeling method in the sheet metal art wherein a wrapper device is utilized to accomplish several process steps.
A further feature of the invention is the provision of a winding and reeling process where a wrapper device is utilized as a material handling device.
A further feature of the invention is the provision of a winding and reeling device wherein the instrumentality ordinarily used to convey and insert an empty reel in a take-up stand comprises a wrapper device.
Other features and advantages of the present invention will become more apparent from an examination of the succeeding specification when read in conjunction with the appended drawings in which:
FIG. 1 is a schematic illustration of apparatus operable to practice the invention, the process being at the point where a supply reel is empty while the take-up reel is full;
FIG. 2 shows the process machinery at the point at which a new supply reel has been inserted and started and the take-up reel has been removed;
FIG. 3 shows the empty reel of FIG. 2 in transit from the supply side of the mill to the take-up side;
FIG. 4 is closely related to FIG. 3 in that it shows the introduction of the empty supply reel into the elevated belt wrapper device; and
FIG. 5 shows the supply reel nested in the belt wrapper and poised over a full take-up reel all ready for introduction into the take-up stand.
Referring now in detail to the drawings, it is appropriate to indicate that the process machine shown is a four high mill, indicated generally by the letter M, and the sheet material being wound is sheet metal, indicated by the letter S.
Obviously the winding and reeling process of the present invention is not limited to sheet metal nor is the proc-. ess machine limited to a four high mill, these items being specifically designated by way of explaining the invention.
Furthermore, the language supply stand and takeup stand are intended to denote devices having rotatable spindles for receiving coils of sheet material packaged upon reels where the supply stand denotes the reel stand arranged at the source from which the material issues while the take-up stand is that similar device located at the wind-up side of a given process machine.
correspondingly, a supply reel is the designation given to a reel while mounted in the supply stand, and take-up reel is that same reel or any similar reel which is carried by the take-up stand.
Supply stand 10 is shown rotatably supporting a reel 11 from which the trailing edge T of a coil of sheet metal C has just run out.
The empty reel 11 is shown cradled in one wing 12 of an S-shaped dual cradle device rotatably carried by an arm 13 operative to be rotated about pivot 14 by suitable means to lift the empty reel 11 out of the supply stand and carry it to the position shown in FIG. 2.
Note that a pair of pinch rolls 16 and 17 are shown open ready to receive the leading edge L of a new supply of sheet metal material S defining full coil 18 wound upon reel 19 carried by movable trolley 21.
FIG. 2 shows full coil C after removal from the takeup stand 22 and disposed upon a movable trolley 23.
An empty reel 24 carried in an elevated position (FIG. 1) by a belt wrapper 26 is lowered to the position shown in FIG. 2 wherein the reel 24 is rotatably mounted between centers in the take-up stand 22 in well known fashion.
Note that the belt wrapper 26 is utilized to convey the empty reel to the stand 22.
The leading edge L of the coil 18 has already been introduced to the mill M and pinch rolls 16 and 17 have been closed to advance the sheet S through the mill. The leading edge L is frictionally pinched between the exterior surface of the reel 24 and the belt wrapper in well known fashion to wind the first several layers or convolutions of sheet material upon the take-up reel.
FIG. 3 shows the belt wrapper device 26 having been returned to its elevated position over take-up stand 22 where it is poised to receive empty reel 11 now having been deposited by the elevator arm 13 upon ramp 27 so that reel 11 has responded to gravity and rolled to the right, as viewed in FIG. 3, across the top of the mill where it is retained by the lip 28.
In FIG. 4 the lip 28 has been lowered about pivot 29 to provide a free run for the reel 11 into the belt wrapper 26 where it is retained, as in a sling, poised in an elevated position for further transfer downwardly where it is received within the spindles of supply stand 22 as has been described in connection with reel 24 of FIG. 2.
The pinch rolls 16 and 17 are relaxed, if desired, during the transfer of the main body of the material through the mill M as there is usually sufficient friction in the '3 a take-up stand drive, and in the mill itself, to continue advance of the sheet material.
FIG. shows the elevator arm 13 returning to the position shown in FIG. 1 wherein opposite sling 31 is utilized to partially encircle reel '19 after all sheet material has been withdrawn to lift it to the position shown in FIG. 2 whereupon the process steps just described are repeated to transfer reel 19 to the other side of the mill where it is utilized as a take-up reel.
It is to be specifically understood that the present invention contemplates a variety of paths of transferring empty reels from one side of a process machine to the other so that they may be utilized in a tape-up stand when empty.
For example, it is anticipated that the reels may be passed under a process machine where they are received in a belt wrapper or around the side of the machine or over the machine as shown in the present description of the invention.
The significant process steps and those which it is desired to protect hinge around the use of the belt wrapper device 26 as a means for conveying or handling an empty reel in addition to the ordinary function of a belt wrapper, namely, insuring tight winding of the first several reels of a new coil of sheet metal material.
