Definitions

  • the present invention refers to an innovative rewinding machine for the productions of industrial logs of paper, fabric, non-woven fabric and similar materials.
  • the invention refers to an innovative feeding device for feeding the cores into the winding section of the rewinding machine.
  • a rewinding machine basically includes a winding section and a feeding section for feeding a cardboard core into the winding section.
  • the cardboard core is conducted in rotation inside the winding section in such a way as to wrap around it a continuous paper tape.
  • the feeding section serves to allow the insertion of a new core into the winding section as soon as the preceding paper log has been completed.
  • Such insertion phase of the new core, and contextual expulsion of the completed roll from the winding section is generally known as "exchange phase".
  • the winding section generally comprises an inferior roller, a superior roller and a press arranged in such a way as to form a winding cradle into which the core is dragged in rotation through the rotation of the said rollers.
  • the press controls the tension of the paper and the reaching of the diameter set in the rewinding machine.
  • the break of the continuous paper tape during the exchange phase, once the roll is completed, is generally controlled through a variation of speed of the rollers that generate a sort of tension in the tape.
  • a rewinding machine is generally provided with a cradle for introducing the core, which is hinged to the inferior winding roller and provided with a curved profile.
  • the cradle being hinged to the inferior roller, can therefore rotate to lower and lift itself with respect to it, forming an insertion path that conducts the core directly into the winding cradle.
  • the core loaded on the introduction cradle through an ordinary loader, therefore stands below the inferior roller up to the moment in which the exchange phase initiates.
  • the introduction cradle rotates in such a way as to bring the core arranged on it in contact with the rotating inferior roller.
  • the core rotates along the introduction cradle, ascending along it up to entering in the winding section simultaneously to the expulsion of the roll now formed. In such a manner, the winding of the new paper log initiates.
  • the cradle must have a precise curved profile that traces the curvature of the inferior roller in such a way that, during all the ascending path of the core, it does not risk either losing adherence or being deflected by it. It is clear that in both cases the result would be that of a variation of speed in the entry of the core and therefore, an incorrect exchange with the consequent block of the rewinding machine. Moreover, also a deformation of the core by deflection can be the cause of a waste product or of a block of the whole rewinding machine.
  • Another technical inconvenience relates to the fact that such a solution with a mobile cradle is kinetically complex. It is in fact necessary to include sensors and a software ad hoc that manages and synchronizes exactly the rotation of the introduction cradle on the basis of the completion of the log or of the winding speed, apart from, naturally, a complex system that allows the rotation of lifting and lowering of the introduction cradle with respect to the inferior roller.
  • the feeding section (7) of the machine of the invention is realized through a support surface (12) and a pushing surface (13) opposed one to the other in such a way as to form a rising conduit (7' ) into which the core results comprised to rise into the winding section (8) .
  • at least the pushing surface (13) is provided with one or more movable tapes (16) (or equivalently movable belts) arranged in correspondence of the said surface (13) in such a way that their movement drags the core in support on the surface (12) along the conduit (V) into the winding section (8).
  • the core pushed by the movable tapes, rotates on the surface 12 along the conduit.
  • Such a structural configuration is particularly advantageous since the two surfaces (12, 13) described can easily be adapted to different diameters of cores by simply translating, therefore moving apart or coming close one from/to the other. Moreover, the entry phase of the core results much more precise, apart from the fact that the structure of the feeding section thus configured is constructively simpler if compared with mobile cradles.
  • such a configuration of feeding section allows an easy and efficient control of the tearing of the continuous tape (for example, paper).
  • the speed of the said tapes is in fact variable at will and, in particular, it is possible to bring it to an inferior speed with respect to the normal winding speed.
  • the core enters the conduit ⁇ !'
  • it pushes the paper that is being wrapped around the log in formation against the tapes (16) .
  • the paper in the point of contact with the said tapes (the paper comprised between core and tapes 16) , is slowed down, thus inducing a tension state that causes the tearing. Therefore, by varying the speed of the tapes it is easily possible to vary the tension state and therefore control the tearing of the continuous tape.
  • the pushing surface (13) is formed by the said one or more tapes (16) arranged in such a way as to form each one a closed ring that surrounds at least the tearing roller (17) and the superior roller (10) along their length.
  • the superior roller is therefore configured in such a way that each closed ring is dragged in rotation just by the tearing roller (17) at its specific rotation speed.
  • a tension element (18, 18') can be further provided for each tape (16), the said tension element (18, 18') comprising an adjustable pulley (18) .
  • Such a pulley therefore allows to adjust the tension of each belt ring 16.
  • the speed of the said tapes can be controlled in such a way that, in correspondence of the entry of the core into the rising conduit (7') the continuous tape (2) comprised between the said tapes (16) and the core (3) acquires the speed of the tapes (16), thus triggering a tension state that causes the tearing of the same.
  • the speed of the tapes (16) can be controlled through an independent adjustment of the rotation speed of the tearing roller (17) .
  • the superior roller (10) includes a plurality of sections placed-, side by side through a bearing assembled idle around the rotation axis of the roller (10) itself in such a way that the passage of each belt (16) around the roller (10) takes place in correspondence of the said bearing in such a way that the speed of the belt (16) results independent from the rotation of the superior roller (10) and results determined by the rotation of the tearing roller (17) .
  • the second support surface (12) is realized through one or more chutes (14) arranged along the inferior roller (9), each one of the said chutes being provided with a support surface (12) opposed, when in use, to the said one or more tapes (16) .
  • the width of the rising conduit (7' ) of the core can be variable in such a way as to result adaptable to cores of different diameters.
  • the support surface (12) and the pushing surface (13) are adjustable at different distances between them in such a way as to vary the width of the rising conduit (T ) of the core.
  • the adjustment takes place through a sliding translation of just of the group comprising the chute (14) and the roller (9) .
  • the said translation can take place along a sliding track.
  • the rising conduit (7' ) can eventually be provided along its length with a first group of blows (21) and with a second group of blows (20) arranged in such a way as to inject pressurised air in the rising conduit (7') .
  • the first group of blows (21) is therefore arranged along the pushing surface (13), while the second group of blows (20) results arranged along the support surface (12) opposite to the group of blows (21) .
  • the first group of blows (21) can be arranged along the conduit in a back position towards the entry of the conduit (T ) with respect to the second group of blows (20) , which is instead arranged in a forward position towards the winding section.
  • the head (31) of the separated tape remains substantially in contact on the core during the whole of a first winding turn.
  • At least a rotatable finger (24) is included for arranging the core (3) on the support surface (12) at the entry of the rising conduit ⁇ !').
  • the tearing of the continuous tape (2) is obtained through the maintenance of a speed of the tapes (16) inferior with respect to the winding speed of the log in formation at least during the entry of the core.
  • the core in entry into the conduit ⁇ !') pushes the continuous tape (2) in contact against the tapes (16) in movement at an inferior speed and induces the paper to slow down in the point of contact.
  • a tension state is generated that causes the tearing, forming a tail (30) of the tape which is winding on the log formed and a head (31) which is winding on the new core in entry.
  • the operation of winding of the head (31) of the tape around the new core is further included.
  • Such an operation includes the activation in succession of a first air blow (21), directed from the pushing surface (13) towards the conduit ⁇ !'), and a second air blow (20) directed from the support surface (12) towards the conduit (V).
  • a first air blow (21) directed from the pushing surface (13) towards the conduit ⁇ !'
  • a second air blow (20) directed from the support surface (12) towards the conduit (V).
  • FIG. 1 shows a lateral view of the rewinding machine in accordance with the invention
  • FIG. 3 shows in an axonometric view the plurality of belts or tapes 16 arranged in a closed-ring manner around the superior roller 10, the tearing roller 17 and the relative pulley 18, while figure 4 shows a lateral view;
  • a rewinding machine 1 is schematically represented in accordance with the present invention .
  • Figure 1 therefore represents a continuous tape 2
  • the rewinding machine 1 is generally provided with perforation rollers 5 on top of the machine and provided with blades that serve to perforate the paper according to a predetermined pitch along its width (generally called paper light) .
  • the continuous tape 2 can pass then through one or more idle wheels 6 in such a way as to maintain always a predetermined advancing speed along its path as well as a correct tension level.
  • the idle wheels can be arranged in any point of the machine in which it may be necessary.
  • Figure 1 in an absolutely non-limiting manner, describes, for example, three idle wheels 6 arranged between the perforation rollers 5 and the feeding section 7 described below .
  • the rewinding machine therefore comprises a feeding section 7 and a winding section 8.
  • the winding section 8 includes an inferior roller 9, a superior roller 10 and a press 11 arranged in such a way as to form a cradle into which the paper is wrapped around the log 4 in formation.
  • the combined rotation of the said inferior roller, superior roller and press causes the rotation of the core 3 arranged between them in such a way that the continuous tape 2 can wrap around it.
  • the feeding section 7 comprises a support surface 12 opposite, at a certain distance, to a pushing surface 13 in such a way as to form a rising conduit 7' through which the core 3 can be conducted into the winding cradle.
  • the distance between the rolling surface 12 and the pushing surface 13 must therefore be such as to allow the contact of the core into the conduit with both surfaces 12 and 13, as better described in detail below.
  • the surface 12 is part of a chute 14 assembled below the inferior roller 9.
  • the chute, together with the inferior roller, can be eventually translated horizontally forward or backward in such a way as to adapt the rising conduit 7' to cores even of very different diameters.
  • a sliding track generally a substantially horizontal track, on which the group comprising the chute 14 and the roller 9 can move in such a way as to be able to adjust the distance with respect to the pushing surface 13 and therefore allow to adapt in a simple manner the rising channel 7' to cores of different diameters .
  • Figure 2 shows constructively in an axonometric view a possible solution of such a chute 14.
  • a constructively simple solution includes the assembly of one or more chutes along the upper surface (that is the length) of the inferior roller 9 and distanced between them of a predetermined quantity.
  • a single chute 14 of a width substantially coinciding with the length of the inferior roller can be included.
  • Both figure 1 and figure 2 show the curved configuration of the part 15 of the chute destined to be fixed under the inferior roller near it.
  • the surface 12 of the chute 14 can also be covered, if necessary, with a high friction material, also called "grip" (for example, glass-paper) , in such a way as to guarantee the better rotation of the core on it.
  • grip for example, glass-paper
  • Figure 1 instead shows the pushing surface 13 opposite to the support surface 12 and described in detail below.
  • the pushing surface 13 is obtained through a plurality of tapes 16, or equivalently belts 16, assembled in a closed-ring manner along the board of the superior roller 10.
  • the tapes 16 therefore form each one a closed ring, passing around the superior roller 10, around the tearing roller 17 and around a tension pulley 18.
  • the rotation of the tearing roller 17 drags and therefore determines the rotation speed of the belts or tapes 16.
  • the superior roller 10 is possible, for example, by realizing the superior roller 10 through a certain number of sections, each one placed side by side through a bearing assembled idle around the rotation axis of the roller 10 itself.
  • the number of sections is equivalent to the number of belts or tapes 16 included, in such a way that the passage of each belt 16 around the roller 10 takes place precisely in correspondence of the said bearing.
  • the speed of the belt is absolutely unrelated from the rotation of the superior roller 10, and is instead determined by the rotation of the tearing roller 17.
  • the idle pulley 18, connected to a tension block 18' also allows the adjustment of the right level of tension of the belt in such a way as to avoid that it slips on the rollers.
  • the tension block is therefore translatable with respect to the superior and tearing rollers precisely for increasing and/or diminishing the tension of the belt.
  • the pulley 18 can be assembled translatable with respect to the block 18' on which it is assembled.
  • Figure 3 and figure 4 for greater clarity, show in an axonometric and frontal view an assembly of the superior roller 10, the tearing roller 17 and the pulleys 18 with the relative belts 16 (for descriptive simplicity, only two have been drawn) , assembled in a closed-ring manner in such a way as to realize the pushing surface 13.
  • Figure 4 particularly indicates with the double arrow the coming close and moving apart direction of the pulley 18 for adjusting the tension of the belt.
  • a first 21 and a second group of blows 20 are arranged along the board of rollers.
  • the blows in the shape of nozzles, can be arranged in correspondence of one or more chutes 14 and respectively in correspondence of one or more tension blocks 18' and serve to blow air into the conduit 7' at a predetermined pressure. Their function will be better described in detail in the descriptive part of the functioning method.
  • Each blow 20 arranged on its own chute 14 can find ahead the relative blow 21 arranged in correspondence of the block 18. Alternatively, the arrangement can be staggered.
