. 4 Claims. (Cl. 214-652) This invention relates to an upender, which while useful in handling a variety of articles, is particularly important in the handling of large rolls or coils of strip steel and tinplated steel, as used in the can manufacturing industry.

The can manufacturing industry has been utilizing larger and larger quantities of steel in roll or coil form. These coils of steel may be as large as 57" in diameter and weigh upwards of 15,000 lbs. The handling of these coils, accordingly, presents a difficult problem. The problem is further aggravated by the fact that the large, heavy coils must be very carefully handled to prevent bending or tearing of the edges as any bent or torn edges would play havoc with the finely adjusted automatic can making machines. Any rough handling of the coils would necessarily result in damage of the coils and a high rate of rejects.

These large heavy coils of steel are mounted in the canmaking machines with their axes or cores horizontal. The coils are, however, received from the steel plants mounted on pallets or skids with their axes or cores vertical. Thus the coils must be taken from the pallets or skids and upended for mounting on the can-making machines. For

the most efficient and economical handling, it must be I possible for the coils to be placed on and removed from the same side of the upender to thereby eliminate the necessity of moving the loading truck or hoist from the front to the rear of the upender and to save the valuable floor space that would otherwise be necessary for such movement from the front to the rear of the upender. Upending of such coils in this manner has been very effectively handled heretofore by apparatus of the 'type described in the oopending Quayle application, Serial Number 690,057, filed October 14, 1958, and assigned to The Yale & Towne Manufacturing Co., the same assignee as the instant application. The Quayle apparatus, while being effective for the purpose, is extremely heavy and utilizes a series of controlled operations that require considerable power mechanism. The present invention provides a much simpler but very effective upender which will also permit the coils to be placed in and removed from the same side of the upender. t

In accordance with the invention, the upender includes a member providing a surface on which a palletized coil may be received with the axis of the coil in a generally vertical position. Means are provided for rotating said member about an axis extending at an angle to said surface and to the horizontal and vertical so that the member moves in a path defining a generally right angle conical plane whereby the member is moved from aposition in which the coil receiving surface extends in a generally horizontal direction to a' position in which the surface extends in a generally vertical upward direction Side elements are provided for engaging the outer periphery of the coil to support the coil as the surface is moved from the horizontal direction to the vertical direction. It will be appreciated that during this rotation the weight of the coil will gradually be accepted by the side elements as the axis of the coil is gradually moved from its generally vertical position to its generally horizontal position. By reason of the relation of the side elements to the coil receiving surface, and the geometry of rotation, no means for clamping the coils are necessary.

The invention contemplates the side elements having 3,016,158 Patented Jan. 9, 1962 surfaces inclined toward each other to form a generally V section to effectively hold coils of a range of diameters. The invention also contemplates spacing the side elements from the coil receiving surface to accommodate the pallets on which the coils are generally mounted. I

The invention having been broadly described, a more detailed description of one embodiment of the invention is given hereunder by reference to the accompanying drawings wherein:

FIG. 1 is a perspective view of an embodiment of the upender of the invention;

FIG. 2 is an elevational'view showing a coil of strip steel mounted on a pallet prior to the placement on the upender;

FIG. 3 is a top plan view showing the upender with a coil mounted on a pallet in place on the upender preparatory to upending the coil;

FIG. 4 is a side elevational view showing the upender and a coil mounted on a pallet in place on the upender preparatory to upending the coil; 1

FIG. 5 is a side elevational view similar to that of FIG..4, but showing the coil upended ready for removal from the upender, and

FIG. 6 is a perspective view showing a lift truck carrying the coil as removed from the upender in the position shown in FIG. 5.

Referring to the drawings and in particular to FIG. 1, the upender includes a'plate member 10 providing a surface adapted, when in a generally horizontal position,

to receive a coil mounted on a pallet with the axis of the.

coil extending in a vertical direction. The pallet P with the coil C thereon is shown in FIG. 2 prior to the placement thereof on the "surface 10a. As is well known, the pallet P allows the forks F, as indicated in FIG. 3, to be inserted beneath the coil and pallet to facilitate the lifting thereof. Thus, the palletized coil may be easily lifted by a fork lift truck and placed onto the surface 10a.

Plate member 10 is welded or otherwise fastened to a table 11. Table 11 is mounted on a base 12 for rotation in a plane which extends at approximately 45 to the vertical and horizontal directions. The plate member 10. may be reinforced bysuitable web 13, best shown in FIGS. 4 and 5, which is welded between the bottom of the member 10 and the table 1 1. The plate member 10 is fastened to the table 11 so that thesurface 10a thereof extends at an angle of approximately 45 to the plane of rotation of the table 11. Upon rotation of the table 11 through 180", the plate member 10- will be moved from a position as shown in FIGS. 1 and 4inwhich the surface 10a extends in a generally horizontal direction to the position as shown in FIG. 5 in which the surface 10a extends in a vertically upward direction from the original horizontal direction. Thus the axis of the coil C is changed from the vertical direction to a horizontal direction in which it may be removed by a lift. truck T with its axis horizontal, as shown in FIG. 6, so that it may .be placed in a suitable machine. As will hereafter be described in detail,

side elements

14 and 15 gradually accept the weight of the coil C as the member 10 is rotated'to change the position thereof from one in which the surface 10a extends in a generally horizontal direction to one in which the surface extends in a generally vertical direction. Because of the provision of the side elements 14 and 1-5 and the geometry of the rotation, no means for clamping the coil during upending is necessary.

The path of movement of the surface 10a may be best described as defining a generally right angle conical plane or surface. Thus a line A-A on the surface 10a would generate a right angle conical surface or plane upon rotation of the table 11 through 360. By reason of this movement the surface 10a is always presented towards the front of the upender, so that the coil 0 may be placed on and removed from the same side of the upender, thus minimizing the movement of the loading and unloading truck and the space necessary for the movement of the truck.

As previously stated, when the table 11 is rotated to change the position of the member from one in which the surface 10a extends in a horizontal direction to one in which the surface 16a extendsin a generally vertical direction, the weight of the coil C is gradually, shifted from the surface 10a and gradually accepted by

side elements

14 and 15 which engage the outer peripheral surface of the coil-C, as best shown in FIG. 3.

Side elements

14 and 15 are conveniently secured together by an integral, inter-connecting portion 16. Portion 16, in turn, is welded or otherwise secured to an upstanding plate bracket 17. Plate bracket 17 is welded. or otherwise secured to the table 11. Suitable reinforcing

webs

18 and 19 extending between, and welded to or otherwise fastened to, the

side elements

14 and 15 .and the plate bracket 17 may be provided.

I As best shown in FIG. 3, the inner surfaces 140 and 15a of

side elements

14 and 15 are inclined toward each other to form a generally V-section, so that they may accommodate and effectively hold coils of various diameters.

As best shown in FIGS. 4 and 5, the bottoms of the side elements '14 and 15 are spaced from the surface 10a to accommodate the pallet P while still allowing the periphery of the coil C to be effectively engaged by the

side elements

14 and 15, so that they may gradually accept the weight as the upender is operated.

The table 11 is adapted to be rotated by a suitable power source 20 through

bevel gears

21 and 22 and shaft 23.. The shaft 23 is secured to the bottom of the table 11 and is journalled in the base 12. Suitable anti-friction means, such as the ball bearing 24 shown in FIGS. 4 and 5, may be interposed between the table 11 and the base 12 to accept the thrust between the table 11 and the base 12 and to decrease friction. As best shown in FIG. 4, the surface 101: while generally horizontal, slopes slightly downward from the absolute horizontal towards the

inclined side elements

14 and 15 so that the tendency is for the coil to move into engagement with the

side elements

14 and 15. t

From the above description it can be seen that there is provided a relatively simple but extremely effective upender. The upender will accommodate coils of various diameters even when the coils are mounted on pallets. The upender may be both loaded and unloaded from the same side, thereby eliminating the necessity of moving the loading apparatus from the front to the rear of the upender and saving the floor space which would otherwise be necessary for such movement.

While one embodiment of the invention has been shown anddescribed, it will be appreciated that this is for the purpose of illustration only and that changes and modifications may be made therein without departing from the spirit and scope of the invention.
