Definitions

  • the present invention concerns an apparatus for overturning coils.
  • coils are transported to the building sites, or in sites anyway prearranged for their manufacturing, in suitable transport vehicles, on which they are arranged with their winding/unwinding axis oriented in horizontal way.
  • the coils are usually unwound for making semi-processed products required by production needs, for example bars or similar products.
  • Apparatuses for unwinding coils, arranged upstream to further apparatuses for example for cutting and folding the unwound metal wires, are currently known as well.
  • Unwinding apparatuses usually comprise a control pin vertically arranged, around which each coil is inserted for performing its unwinding. Handling of coils, in particular handling performed in different zones of the production line, as well as the overturning from the horizontal axis configuration, for transport, to the vertical configuration, for unwinding, is really dangerous, because of the weight of the same coil, as well as because of the space required by the overturning operation and inserting operation in the correspondent unwinding apparatus of the production line.
  • Patent application no. WO-A-90/15675 discloses a method and arrangement for handling a coil of metal packing wire, whereby a heavy coil of metal wire is transported in a horizontal attitude with the help of a lifting arrangement to an arrangement which has a central upright capable of being pivoted between a horizontal and a vertical end position. The coil is placed on the horizontal upright, and a reeling-off crown is also pushed onto the upright, whereupon the upright is pivoted up into its vertical working position for the reeling off of the wire from the coil. Nevertheless, the mentioned solution is not able to effectively overcome the aforesaid drawbacks.
  • the task of the present invention is that of solving the cited problems, devising an apparatus which allows to efficiently overturning coils for example of metallic wire.
  • a further scope of the invention is that of providing an apparatus which can be placed on already existing production lines.
  • a further scope of the invention is that of providing an apparatus for overturning coils of simple conception, with a securely reliable functioning and versatile use, as well as relatively economic cost.
  • Cited scopes are attained, according to the present invention, by the apparatus for overturning coils according to claim 1.
  • the apparatus comprises a carrying framework and a support structure articulated to the carrying framework according to a tilting axis substantially horizontal, the support structure comprising a first support plane and a second support plane substantially reciprocally orthogonal.
  • the tilting structure comprises as well centering means, for example a pin substantially orthogonal to the cited first support plane, for centering and inserting inside a hollow pin of a bell-shaped reel support.
  • the apparatus is suitable to perform the overturning of coils already inserted in respective bell-shaped reel supports, which are therefore already oriented and prearranged for the unwinding.
  • the apparatus carries the insertion pin of a bell-shaped reel support in a removable way.
  • Such solution makes the embodiment particularly versatile because it combines the possibility of overturning on the tilting support also coils without reel support.
  • the apparatus can be made self-sufficient from the energetic point of view.
  • the overturning of the tilting structure can occur as a consequence of the same weight of the bell-shaped support reel and of the coil to be overturned, while the return stroke can be actuated by actuator members, elastic or pneumatic means suitably preset, previously loaded by the overturning active stroke.
  • the carrying framework is provided for each working apparatus of the plant and, providing the use of coupling means rotatable between the centering means of the bell-shaped support and the tilting structure, it also provides the function of unwinding.
  • the apparatus can be displaced for reaching different operative sites placed in the production plant, through suitable transport means.
  • the tilting structure is preferably articulated to the top of the carrying framework. It allows the overturning of the bell-shaped reel supports and/or of the coils inside the space of the same apparatus, minimizing in such way the required manoeuvring distance.
  • the loading of the overturning apparatus, with the second support surface substantially horizontal can be made by placing the transport vehicle of the coil at the side of the uprights of the framework, instead of frontally to the base of the framework. It allows to place the apparatus at a minimum distance from the surrounding walls and therefore to optimize the production spaces.
  • the arrangement of the articulation at the top of the carrying framework allows to place the wires unwound by the coils at a height sufficient for a possible immediate use, without interfering with other parts of the apparatus.
  • FIGS. 1 and 2 show respectively a perspective exploded and rear view of the apparatus according to the invention, equipped with a bell-shaped reel support;
  • FIGS. 3 and 4 show respectively a front and lateral view of the same apparatus equipped with the cited device.
  • the apparatus 1 comprises a carrying framework 2, a tilting support structure 3, centering means 4 for a bell-shaped reel support 5.
  • Actuator members 6 can be usefully provided as well, suitable to positively operate at least one stroke of the tilting motion of the tilting support structure 3, as better described hereafter.
  • the bell-shaped reel support 5 comprises a platform 50 preferably shaped by a plurality of rods arranged radially and orthogonally to a central pin 51 constrained to them through a plurality of arms 52.
  • a coil to be unwound is suitable to be inserted around the central pin 51 of the bell-shaped reel support 5, supported by the plane shaped by the rods of the platform 50.
  • the bell-shaped reel support 5 comprises as well a perimetrical containment enclosure 53, which extends from the rim of the circular platform 5.
  • the framework 2 which can be constrained to the floor in fixed way or in removable way, for being for example lifted, comprises a base 20, for example made by a couple of horizontal supports, and a wall 21, for example made by one or more vertically arranged uprights 21.
  • a shaft 22 is rotatably constrained suitable to define the tilting axis of the tilting structure 3.
  • the tilting structure 3 shapes a structure at right angles suitable to define through respective shelves a first support surface 30 and a second support surface 31 for a coil to be overturned or for a bell-shaped reel support 5.
  • the first support surface 30 of the tilting structure 3 comprises a couple of mobile arms
  • the second support surface 31 preferably comprises a curved wall, with its concave surface turned towards the first support surface 30.
  • the first support surface 30 is suitable to receive in support or in abutment the base of a coil to be overturned or the platform 50 of a bell-shaped reel support 5.
  • the second support surface 31 preferably comprises a curved wall suitable to receive in support or in abutment a correspondent curved wall of a coil to be overturned or the containment enclosure 53 of the bell-shaped reel support 5.
  • the tilting structure 3 is constrained rotatable about the shaft 22 preferably on the back of the second support surface 31, so that the tilting structure 3 is mobile alternatively between a loading configuration in which the first support surface 30 is substantially vertical abutting the base of a coil or of the platform base of a bell-shaped reel support 5 and an overturned configuration in which the first support surface 30 is substantially horizontal and receives in support the above mentioned base or the above mentioned platform 50.
  • the tilting structure 3 comprises as well centering means 4 for a bell-shaped reel support 5.
  • the centering means 4 shapes a centering pin interposed between the mobile arms 31 and orthogonally oriented to them.
  • the centering pin 4 is constrained to the tilting structure 3 preferably in removable manner.
  • the centering pin 4 allows to insert inside the hollow pin 51 of the bell-shaped reel support 5, for the firm positioning of the reel supports 5 on the apparatus 1.
  • the centering means 4 can be constrained to the tilting structure 3 through the interposition of bearing coupling means, of the type of rolling bearings or fifth wheel, for enabling the apparatus 1 to provide the function of unwinding apparatus, as well as that of overturning of the coils.
  • the apparatus comprises actuator members 6 comprising for example a pneumatic or hydraulic storage actuator member, suitable to store the actuator fluid during the overturning stroke, operated by the force of gravity, and to positively operate the back stroke towards the load configuration of the coil or of the bell-shaped reel support 5.
  • the actuator member 6 is articulated in suitable way between the framework 2 and the tilting structure 3.
  • the reel support 5 is centred on the apparatus 1 through the centering caused by the insertion of the same reel support around the pin 4 integral with the tilting structure 3, the first surface 30 being in substantially horizontal position.
  • the tilting structure 3 is operated preferably by the force of gravity, overturning the reel support 5 in an overturned configuration in which the central pin 51 is horizontally arranged.
  • the coil to be unwound is transported, with its axis horizontal, to the loading position in which the apparatus 1 is arranged, and loaded on the bell-shaped reel support 5 overturned in horizontal position, for inserting around the fixing arms 52 which surround the central pin 51, and with the curved lateral surface of the coil substantially supported by the first support surface 31, preferably thickened according to the size of the coil.
  • the tilting structure 3 in overturned configuration, with the first operative surface 30 substantially vertical, is again turned, preferably by force of gravity, for returning to the initial position, in which the first support surface 30 receives in support the bell-shaped reel support 5 and the coil inserted in its inside.
  • the coil is oriented with vertical axis, therefore it is correctly prearranged for being drawn with suitable lifting means and inserted on the rotating base of an unwinding reel of an operative machine.
  • the provided overturning apparatuses are a plurality, arranged at the place of each unwinding reel provided in the production line, in which overturning and discharging suitably the coils already prearranged for the next manufacturing.
  • the centering means 4 are constrained to the tilting structure through the interposition of rolling means, for example of the type of the fifth wheel.
  • the described apparatus attains the scope of performing the overturning of the coils in an efficient way, in particular coils of metallic wire.
  • the apparatus together with the previous disclosed advantages, has the further advantage of reducing the amount of space required for loading and discharging the coils, therefore allowing an overturning of the coils which minimizes the spaces required by the apparatus. More precisely the articulation of the tilting structure to the top of the uprights of the carrying framework allows an overturning rotation of the coil which occurs substantially inside the space of the apparatus. Moreover, the articulation of the tilting structure at the second support surface, suitable to abut the lateral surface of the coil, allows to access the apparatus, for the loading, from the uprights side, decreasing the minimum distance from the walls required for the installation of the apparatus.
  • the embodiment of the invention may vary depending on the requirements.
