Abstract
Description
- The present invention relates to an apparatus for handling hollow cylindrical bodies, particularly sheet metal coils.
- It is known that bulky cylindrical bodies such as sheet metal coils or the like are currently handled by using apparatuses provided with grip elements of various kinds (bridge cranes, free-standing cranes, fork-lift trucks) that lift and carry the coils both for loading and unloading them on and from means of transportation, such as trains, ships or trucks, and for their movement within an industrial processing area.
- However, with particular reference to the case in which such coils must be individually and occasionally moved among multiple stations of a processing cycle, known apparatuses are difficult to use owing to their very limited maneuverability and/or their significant space occupation.
- Known apparatuses in fact require the frequent intervention of qualified operators, who manually push and roll said coils in order to move them proximate to said apparatuses and arrange and orientate them, so as to allow them to be gripped, and fix the coils to the grip elements with which the apparatuses are provided.
- It is noted that sheet metal coils or the like have considerable dimensions and weight, said weight being able to reach values close to 40 tons, and their manual handling is therefore not only difficult and slow but also tiring and dangerous for operators.
- The aim of the present invention is to eliminate the above noted drawbacks of known types of handling apparatuses, by providing an apparatus for handling hollow cylindrical bodies, particularly sheet metal coils, that allows easy and improved maneuverability and allows to handle the coils simply, safely and rapidly within an industrial area and to limit the intervention of qualified operators and consequently contain labor costs and improve workplace safety.
- Within this aim, an object of the present invention is to achieve the above aim with a structure that is simple, relatively easy to provide in practice, safe in use, effective in operation, and relatively low in cost.
- This aim, this object and others that will become better apparent hereinafter, are achieved by the present apparatus for handling hollow cylindrical bodies, particularly sheet metal coils, characterized in that it comprises a frame for supporting means for gripping said body, which are associated therewith so as to rotate and perform a translational motion respectively about a substantially vertical axis and along a substantially horizontal axis, and first and second actuation means, said frame being associable with self-propelled lifting and transport means.
- Further characteristics and advantages of the present invention will become better apparent from the detailed description of a preferred but not exclusive embodiment of an apparatus for handling hollow cylindrical bodies, particularly sheet metal coils, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Figure 1 is a side view of an apparatus according to the invention associated with self-propelled means, such as a lift truck, in the configuration for lifting and carrying a coil;
- Figure 2 is a schematic front view of the apparatus according to the invention, associated with a lift truck in the configuration for resting the coil on the ground;
- Figure 3 is a schematic front view of the apparatus of Figure 2 in the configuration for releasing the rested coil;
- Figure 4 is a schematic side view of an apparatus according to the invention;
- Figure 5 is a schematic front view of the apparatus of Figure 4;
- Figure 6 is a schematic plan view of the apparatus of Figure 4.
-
- With reference to the figures, the reference numeral 1 generally designates an apparatus for handling hollow cylindrical bodies, particularly sheet metal coils R.
- The apparatus 1 comprises a
frame 2 that supports, in a suspended configuration, means for gripping the coil R, which are constituted by afork 3; thefork 3 is associated with theframe 2 so that it can rotate and perform a translational motion respectively about a vertical axis A and along a horizontal axis B. - The
frame 2 is anchored to self-propelled lifting and transport means 4, such as for example a lift truck. - The
frame 2 is constituted by two mutually spaced andparallel uprights 5, which are connected bycross-members 6 and from which abracket 7 protrudes forward. - The
bracket 7 is arranged substantially horizontally and thefork 3 is suspended below it. - The vertical axis A is formed by a pivot, not shown because of a known type, which is supported by the
bracket 7; rectilinear guiding means, constituted by atubular body 8, are associated below said pivot so that they can rotate about the vertical axis A. - The
body 8 forms the horizontal axis B. - The
fork 3 is substantially C-shaped: theupper portion 9 of the C-shape is telescopically inserted in thebody 8 so as to be parallel thereto and able to slide with a reciprocating rectilinear motion along the horizontal axis B, while thelower portion 10 of the C-shape is suitable to enter thecavity 11 of the coil R. - The apparatus 1 further comprises first and second means 12 and 13 for actuating the rotation of the
body 8 about the vertical axis A and the translational motion of thefork 3 along the horizontal axis B. - The
fork 3, being coupled to thebody 8, rotates rigidly with it about the vertical axis A. - The first actuation means 12 comprise a
vertical motor shaft 14, which is supported by thebracket 7, with respect to which it protrudes downward, and is connected to thebody 8 by way of conventional means for transmitting rotary motion, such as gears, which are constituted by a sprocket 15 and atoothed wheel 16 that are mutually coupled. - The
sprocket 15 is keyed to the lower end of themotor shaft 14 and thetoothed wheel 16 is fixed, so as to be coaxial to the vertical axis A (pivot), to aplate 17 that is in turn monolithically mounted at the top of thebody 8. - Means for free rotation, such as axial and radial bearings of the conventional type, are interposed between the pivot that forms the vertical axis A, the
toothed wheel 16 and thebody 8, and allow the rotation of thebody 8 with minimal friction. - The second actuation means 13 comprise a
hydraulic cylinder 18, which is arranged substantially coaxially inside thebody 8 and acts on theupper portion 9 of thefork 3. - Advantageously, a side-fit coupling is provided between the
body 8 and theupper portion 9 and their mutual sliding along the axis B is guided by sliding blocks and rails. - The apparatus 1 further comprises
rectilinear guides 19, which are substantially vertical and are mounted monolithically with respect to the self-propelledmeans 4; theuprights 5, and therefore theframe 2, are coupled to the guides so that they can slide with a reciprocating rectilinear motion. - Conveniently, if the self-propelled means 4 are constituted by a lift truck, the
rectilinear guides 19 are constituted by the rectilinear guides with which the truck itself is provided and along which aslider 20 can slide; such guides are usually provided with inclination adjustment means 21 of the hydraulic type. - In this case, the
frame 2 is mounted monolithically with respect to theslider 20; for this purpose, to the rear of theuprights 5 there areupper lugs 22, in each of which there is a hole for the passage of a supportingpivot 23 that is anchored to theslider 20. - Moreover, to the rear of the
uprights 5lower plates 24 for coupling and fixing to theslider 20 are also provided. - As an alternative, the
frame 2 can be raised by means of the forks with which a lift truck is usually provided; for this purpose, theframe 2 is provided to the rear with slots in which the forks are inserted. - Finally, the apparatus 1 is provided with means for actuating the first and second activation means 12 and 13, which comprise for example electric valves that are connected to buttons or levers that are arranged inside the cab of the self-propelled
means 4 and can thus be reached and operated easily by the operator assigned to handling the coil R. - The rotation of the
body 8 about the axis A allows to align thelower portion 10 with thecavity 11 of the coil R, while sliding along the axis B of theupper portion 9 allows to insert and extract thelower portion 10 from thecavity 11 respectively to pick up and release the coil R. - The sliding of the
frame 2 along therectilinear guides 19 instead allows to lift and rest the coil R with respect to the ground or any other supporting surface, while the self-propelled means 4 with which the apparatus 1 is associated allow to transport the coil R in any industrial processing area. - In practice, it has been found that the described invention achieves the intended aim and objects, i.e. that is provides an apparatus 1 that can be maneuvered easily and allows to handle coils of sheet metal easily and simply.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
- All the details may further be replaced with other technically equivalent ones.
- In practice, the materials used, as well as the shapes and the dimensions, may be any according to requirements without thereby abandoning the scope of the protection of the appended claims.
