Definitions

  • the present invention relates to the field of paper converting machines and precisely it relates to a machine for processing the head and tail cut portions, i.e. the scraps, produced by a transversal cutting machine of logs of paper and similar material.
  • rolls of paper for example absorbent for wipers or toilet paper
  • machines are known that work starting from large reels of a web having a large transversal width. From these machines logs of paper are delivered, having length equal to said transversal width of the web, and which are to be cut off into smaller portions, for example rolls of toilet paper, industrial rolls of wiping paper, etc.
  • the transversal cutting machines have the object of cutting off rolls from the logs of paper and comprise normally a bench with one or more slides onto which the logs to cut are placed in turn.
  • the head and tail ends of the log are then trimmed and the trimmed portions are taken away as scraps along an outlet conveyor.
  • pushing devices are provided that, after that sensors distinguish the trimmed portions from the rolls, the trimmed portions are pushed selectively sideways.
  • zones of fall are provided of the trimmed portions obtained by distancing some belts so that they allow the passage of the rolls, which have larger size, causing only the trimmed portions to fall.
  • the scraps withdrawn are then recycled usually within the same plant of production to obtain however a poorer product, owing to the contemporaneous presence of paper of high quality, for the part of roll made of "tissue” paper, and of poorer paper or cardboard of the core. This causes a considerable waste of material that previously was of high quality and potentially was still recyclable upstream in the same production process.
  • the means for removing a partially cut scrap portion from a core on which it is wound comprises at least an element to provide an air flow.
  • the means to provide an air flow can be means to provide a suction of a partially cut scrap portion, said means being arranged opposite to the cutting means with respect to the scrap.
  • the means to provide an air flow can provide blowing means.
  • the means for engaging with the core of the scrap to allow the action of the cutting means comprise a plurality of elongated elements suitable for capturing the scraps and to engage with them at the core when these reach an introduction area.
  • the above described elongated elements are arranged at a predetermined distance on a conveyor operated by motor means.
  • the means for engaging with the core of the scraps can engage the core capturing the scrap below or above with respect to a trajectory of the scraps. More in detail, in the first case the engagement step of the core of the scraps consists of putting the scrap on the elongated element, whereas in the latter case the scrap is constrained between the elongated element oriented towards below and the conveyor on which it proceeds.
  • the cutting means that partially cuts the scrap can reciprocate along a direction substantially orthogonal to the conveying direction of the scraps.
  • the reciprocation of the cutting means is effected by at least one actuator.
  • upstream from the sawing station means are provided for aligning the scraps before bringing them to the cutting means.
  • the means for aligning the scraps provide a first and a second belt arranged converging in a conveying direction of the scraps up to an outlet having the same diameter of the scraps and suitable for transmitting a rotation to the scraps towards the outlet. More in detail, the scraps at the end of the cutting step, executed for example by a transversal cutting machine, are located on a conveyor belt that carries the scraps at the means for aligning them.
  • a method for separating a scrap portion from a core on which it is wound provides the following steps:
  • a machine 1 for separating a scrap portion 20 from a core 21 on which it is wound, such as by machines for the production of rolls of paper. It comprises means 40 for engaging the core 21 of scrap 20 in order to cause a blade 30, for example of circular shape, to partially cut scrap 20 in a precise way.
  • blade 30 partially cuts scrap 20, in a plane substantially parallel to the axis 25 of scrap 20, up to a determined depth. In other words, blade 30 partially cuts scrap 20 up to achieve a generatrix of the core.
  • the partially cut portion of scrap 20 is withdrawn from core 21, on which it was wound.
  • This step can be executed by an air flow generated by a blower or a fan 50 that separates the partially cut portion of scrap 20 from core 21 in one or more steps.
  • the successive steps can be carried out with a suction mouth that spans three or four elongated elements of the conveyor, in order to extend the suction for a certain distance.
  • the successive steps can be carried out by distinct devices.
  • fan 50 can be arranged opposite to blade 30 with respect to the scraps 20 and cause the suction of the partially cut portion of scrap 20.
  • the fan 50 can be arranged at the same side with respect to blade 30 for blowing air on partially cut portion of scrap 20.
  • the major part of partially cut portion of scrap 20 is withdrawn and in further steps also the coils of paper that remain constrained to core 21 are subject to suction, "unrolling" them from the core same.
  • the separation of the partially cut portion of scrap 20 from core 21 is made through grasping means 55 that catch the scrap 20, for example radially, and withdraw it from the working area.
  • the second steps i.e. the removal of the coils still wound about core 21, can be executed in this case by a smaller fan 155.
  • scrap 20 is engaged at core 21 for allowing blade 30 to make precisely a partial cut and in particular for allowing to cut up to a measured depth without cutting also core 21.
  • the elongated elements 40 can engage core 21 of scraps 20 capturing them from below (figures from 4 to the 6 and figure 8) or alternatively, from above (figures from 1 to the 3, figures 5 and 7), with respect to the trajectory of scraps 20.
  • scrap 20 can be put on an elongated element 40 (figures from 4 to 6 and figure 8) or alternatively, can be constrained between the elongated element 40 and a support plane 41 on which scrap 20 moves during the whole process (figures from 1 to 3, figures 5 and 7).
  • the engagement of scraps 20 by elements 40 can be made, as diagrammatically shown in figures 2 and 3, by arranging elongated elements 40 on a conveyor chain 45 moving towards the scraps 20. This way, when the scraps 20 reach an engagement area 60 they capture the scraps 20 same at the relative cores 21.
  • FIG. 4 some possible exemplary embodiments are shown of the machine 1 and in particular of the cross section deputed to the introduction of the scraps 20 on elongated elements 40.
  • FIG. 4 and 5 the possibility is shown, according to the invention, to use chute elements 42 arranged orthogonally to the conveying direction of the scraps (figure 4) or inclined with respect to it (figure 5) that guide scraps 20 on a conveyor belt 43 towards the elongated element 40.
  • a preliminary step is provided of aligning the scraps 20 for optimising the process and in particular for speeding up the next operations of cutting and withdrawing the partially cut portion of scrap 20.
  • the step of aligning can be carried out for example by a first belt 2 and a second opposite belt 3 that rotate in equal directions, so that the two segments of belt facing the scraps move in an opposite direction.
  • the belts 2 and 3 are arranged converging in a conveying direction of the scraps 20 up to an outlet. This way, the access to the cutting station is allowed to a single scrap 20 at a time.
  • blade 30 that partially cuts scrap 20 can reciprocate along a direction substantially orthogonal to the conveying direction of scraps 20.
  • the reciprocation of blade 30 can be operated by at least one actuator 35, for example of pneumatic type. As shown in particular in figure 3 the reciprocation of blade 30 can be obtained arranging it on a carriage 37 sliding along guide 38.
