Field of the Invention The present invention is directed to a coil pickup device and particularly a device enabling the shifting of the orientation of the coil during lifting and lowering.
2. Prior Art In many manufacturing facilities, coils of wire or coils of sheet metal are stored with the axis of the coil being in a vertical orientation. Since most of these coils are placed on unwinding devices with their axis in a horizontal position, the coil must be lifted and turned to change the orientation of its axis. Presently, such handling is done by using a fork lift truck to change the orientation and to lift the roll or coil. The use of a fork lift truck is a time-consuming method and in many cases has resulted in injuries to personnel when the roll slips off of the fork lift.
SUMMARY OF THE INVENTION The present invention is directed to a pickup device which is attached to an annular article or object such as a coil of wire or metal strips and enables the shifting of the orientation of the axis of the coil while being raised or lowered. In the preferred embodiment, a member having a support surface and a shoulder for engaging the coil is connected to a flexible member passing over a pulley and terminating at the other end with a yoke which is detachably connected to the member.
Accordingly, it is an object of the present invention to provide a device for handling annular articles which can engage the annular article disposed in any orientation.
Another object of the present invention is to provide a device for handling annular articles which engage the article in any position and will enable the axis of the article to shift between vertical and horizontal orientations during raising and lowering of the article.
Other objects, features and advantages of the invention will be readily apparent from the following description of the preferred embodiment thereof, taken in conjunction with the accompanying drawings, although variations and modifications may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates a coil of material being lifted by the present invention;
FIG. 2 illustrates the present invention assembled on a coil of material shown in cross section prior to lifting of the coil;
FIG. 3 is an enlarged view of a portion of the device of the invention as shown in FIG. 1; and
FIG. 4 is a view taken on line IVIV of FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT The principles of the present invention are particularly useful in a pickup device generally indicated at 10 in FIG. 1 for handling an annular article generally indicated at 11 which is illustrated as a coil of sheet metal. Although the device is illustrated lifting a coil of sheet metal, the device 10 has utility in lifting coils of wire or other annular articles such as large annular rings.
The device 10 is formed of a body member 12, a yoke 13, flexible means 14 and a pulley means 15. The flexible means 14, which can be either a web or strip of any flexible material or a chain-type belt, is threaded over a roller 16 of the pulley means 15 and has one end 17 connected by a pivotal connection to the body member 12 and the other end 18 rotatably connected to the yoke 13. The pulley means 15 has a housing 19 for rotatably supporting the roller 16 and the housing has means, such as an aperture 20, for connecting to a lifting hook 21 of a lifting device such as an overhead crane.
The body member 12 has a flat L-shape configuration with a short leg or portion 22 and a long leg or major portion 23. For
supporting the inner circumferential surface of the coil 11, the long leg 23 has a support surface 24 which terminates at one end in an upstanding shoulder 25 formed by the short leg 22. The short leg 22 is provided with an aperture 26 which is oblong and receives a clevis 27 which is connected by a connecting pin 28 to the one end 17 of the flexible means 14 to form the pivotal connection. On a surface 29, which is opposite the support surface 24, the major portion or long leg 23 is provided with a plurality of spaced slots 30 which are inclined to the surface 29 at an angle of approximately 60. The slots receive a pin 31 of the yoke member 13 to detachably interconnect the yoke member 13 to the body member 12. As best illustrated in FIG. 3, the end of the major portion 23 of the body member 12 is provided with a handle formed by an aperture 32 having an oblong configuration.
The yoke 13, as best illustrated in FIG. 4, is formed of a pair of metal members 33,33. Each of the metal members 33,33 has a first portion 34 and an offset second portion 36, which is connected to the first portion by the intermediate portion 38. The two metal members 33,33 are assembled together with three pins which are the pin 31, a second pin 40 and third pin 41. To maintain the desired spacing between the member 33,33, the pins 31, 40 and 41 are provided with spacers which are either integral or separate and to hold the yoke together the ends of the pins 31, 40 and 41 are provided with threads to receive nuts. As assembled, the first portions 34,34 are spaced apart by thepins 31 and 40 to form a rectangular shaped aperture 42 which telescopically receives the major portion 23 of the body member 12 during formation of the detachable connection. The second portions 36,36 are spaced apart in the assembled yoke 13 and are interconnected by the pin 41 which receives a bight 44 of the other end 18 of the flexible means 14.
To form a connection'between the body member 12 and the yoke 13, the yoke is telescopically disposed over the major portion 23 and the pin 31 is placed in one of the slots 30 which enables adjustment in the connection of the yoke 13 and body member 12 to provide the necessary distance between the shoulder 25 and the yoke 13 for the width of the coil 11. With the pin 31 received in the slot 30, the distance between the pin 40 and the support surface 24 is of a sufficient amount to allow the yoke 13 to pivot on the pin 31 through an angle of approximately or to pivot approximately 45 from the vertical position illustrated in FIG. 3. The pin 40 prevents further pivoting and as described hereinafter acts as a safety means to prevent disengagement of the pin 31 from the slot 30.
As illustrated in FIG. 2, a coil is usually stored on one of its sides 48 or 49 so that the axis of the coil is in a vertical orientation. To provide a space between the side 48 of the coil and a storage surface 50, which may be a floor, another coil or a pallet, the coil is usually laid on a spacer such as a board 51.
To lift and turn a coil stored on its side, the body member 12 of the device 10 is inserted between the coil 11 and storage surface 50 and positioned with the shoulder 25 engaging the side 48 of the coil and the support surface 24 engaging the inner circumferential surface of the coil. The yoke is then telescopically received on the major portion 23 and moved toward the side 49 of the coil and the pin 31 of the yoke 13 is inserted in one of the slots 30 which is selected to form the detachable connection with the necessary space between the yoke 13 and the shoulder 25. As assembled on the coil, the flexible means 14 is shifted on the roller 16 to have a long leg 14a extending to the body member 12 and a short leg 14b extending to the yoke 13.
During the lifting the roll or coil 11 will pivot on a point of contact 53 with the spacer 51 or floor 50 which point of contact is diametrically opposite from the point of engagement of the device 10. During the pivoting, the roller 16 rotates to allow changes in the lengths of the legs 14a and 14b as the coil is upended with its axis being eventually moved or shifted to a substantially horizontal position. When in the upright position, the legs 14a and 1417 will be substantially equal as illustrated in FIG. 1.
During lifting of a coil disposed on its side such as 48, the position of the yoke 13 is such that the lifting force applied thereto will tend to rotate the body portion 12 which helps start the rotation of the roller 16. As the roller rotates to equalize the lengths of the legs 14a and 1412, the yoke will 1 pivot to the vertical position as illustrated in FIG. 3.
After lifting the coil 11, it can be placed on a coil handling device or on an unreeling machine and then after the weight is taken off of the flexible means 14, the yoke can be disconnected from the body portion 12 by removing the pin 31 from the slot 30 and then shifting the yoke off of the leg 23. As mentioned above, the pin 40 is a safety device which prevents the yoke 13 from pivoting in the slot 30 to such an extent that the pin 31 might become disengaged with the slot 30 if the point of lifting were offset to one side by too great a distance.
The lifting or pick up device can also be used for putting coils in a stacked or stored position resting on one of their sides. When using the device 10 to store coils, the coil is lowered until it makes contact with the supporting surface or spacers. Then the axis of the coil is shifted from the horizontal orientation to the vertical orientation with the flexible means 14 moving on the roller 16 to vary the lengths of the legs 14a and 14b. When the coil 11 is resting on its side such as 48, the yoke 13 is removed and then the body member is withdrawn.
Although minor modifications might be suggested by those versed in the art, it should be understood that 1 wish to embody within the scope of the patent warranted hereon all such modifications as reasonably and properly come within the scope of my contribution to the art.
