Definitions

  • the present invention concerns a device and a method for changing the reel in an unwinder, which may be used, in particular, for paper reels and other materials in web form.
  • unwinders As is known, the function of unwinders is to unwind a web material from a reel to supply it to one or more machines located downstream in a determined work cycle .
  • an unwinder comprises a bearing structure on which are arranged two conical supports intended to engage two corresponding mandrels inserted bilaterally in the central tubular nucleus of the paper reel, called also "core", in such a way that the reel is free to turn around the respective axis and the free unwinding of the respective web is allowed .
  • a relatively important phase in the use of unwinders is the changing of the reel, that is the operation with which a nearly empty reel is replaced with a new reel . This operation, which must guarantee the continuity of the supply of web to the machines located downstream, is most frequently carried out in an almost exclusively manual way with both the reels stopped.
  • the first reel which is nearly empty, is moved away from the support cones, between which an operator, with the aid of a mechanical lifter, then fits a new reel to be unwound; the operator must also manually slacken an end portion of the paper web supplied by the nearly empty reel and connect that portion of web to the portion at the start of the web on the new reel . Besides this, the operator must manually cut the finished web, in a point upstream from said connection . It is clear that the operation described above is closely linked with the skill of the operator and, in the event of failed, imprecise or faulty connection of the webs of the two reels involved, it leads to interruptions in the production cycle downstream from the unwinder, with economic damages due to the resulting production loss .
  • the main aim of the present invention is to overcome the above-mentioned inconveniences , that is to optimise and simplify the reel changing operation .
  • This result is achieved, in conformity with the present invention, by adopting the idea of realising a device and a method having the characteristics described in the independent claims .
  • Other characteristics of the invention are the obj ect of the dependent claims .
  • Thanks to the present invention it is possible to change the reel automatically, precisely and in complete safety, without having to assign this operation to particularly expert or qualified personnel .
  • a device in conformity with the present invention is relatively simple and economic to make, and, in relation to its mechanical and functional simplicity, it is reliable even after a prolonged period of use .
  • Figs .1-6 illustrate a possible embodiment of a device in conformity with the invention, represented in a schematic side view with transparent parts and others omitted for greater clarity, during successive operative phases of changing the reel;
  • Figs .7-10 are enlarged details of Figs .4 , 5 and 6 ;

  • Fig .19 schematically represents the device for mechanically j oining the webs coming out of the unwinder illustrated in Figs .11-15 , seen on a plane at a right angle to the advancing direction of the webs ;
  • ⁇ Fig . 20 is a simplified block diagram of the connections between some of the parts of the present unwinder .
  • the numerical reference 1 indicates , on the whole, a possible embodiment of an unwinder according to the present invention .
  • upstream and downstream refer to the direction of advance of the web (towards the right in the drawings ) .
  • end portion or tail end defines that portion of the web of a reel that is finishing, obtained by cutting and intended to be j oined to the initial portion or "head portion or end” of the web of a reel intended to replace the one that is finishing .
  • the unwinder 1 is provided with a pair of conical supports, of the same type as those used in conventional unwinders , suited to engage two mandrels 50 inserted from opposite sides in the core 3 of a reel 2 during the unwinding of the latter, so as to define a horizontal axis around which the reel itself is free to rotate .

  • the skirt of the cylinder 8 is fixed to the corresponding side of the frame 10 by means of a pin 11.
  • the activation of the cylinder 8 that is the extension of the respective rod 9, determines a rotation of the arm 5 around the pin 7 ( in a counterclockwise direction with reference to the drawings ) .
  • Said rotation of the arm 5, determined by the activation of the cylinder 8 causes the reel 2 to be moved away from the unwinding station Sl towards a temporary parking station S2, which is at a lower height than the unwinding station Sl and is connected to the latter by means of an inclined plane 13.
  • the portion 12 of the arm 5 exerts a thrust on the reel 2 , bringing the latter onto the inclined plane 13 where the reel moves, by gravity, until it arrives at the temporary parking station S2 (see arrow F in Fig .2 ) .

  • said cylinder 22 is shown only in Fig .14.
  • the activation of the gear motor 17 determines a rotation of the arms 15 around the pins 16. Said rotation corresponds to a lowering of the reel 2 ' supported by the hooks 21 , that is a shift towards the unwinding station Sl where the reel 2 ' is passed to the arms 5.
  • the activation of the cylinder 22 with a retraction of its rod 24 , determines a rotation of the respective hook 21 (counter-clockwise in the drawings ) , allowing the release of the hook and the return of the arms 15 into the initial raised position .
  • the aforesaid cones are open, that is released from the respective mandrels 50 , while they are arranged in a position to engage the mandrels 50 only after a reel has been definitively positioned in the station Sl .
