Definitions

  • the present invention refers to an improved rewinding machine for rewinding and forming a paper roll.
  • Machines or treatment groups for winding paper intended for domestic use, in particular paper used for purposes such as toilet paper, kitchen rolls, and the like, known today, comprise elements which guide the paper being delivered and they control their proper winding on a core in order to provide a finished roll referred to as a "log".
  • rewinding machines are provided with two winding rollers and a third pressure roller.
  • the first two rollers determine the winding of the paper around a roller as the diameter increases while the third roller, alongside cooperating in such winding operation, keeps a given pressure on the roll or log ensuring its proper and perfectly compact winding.
  • the two rollers are arranged at a fixed position with respect to the framework and support the log, drawing the paper.
  • One of the two abovementioned winding rollers especially the one arranged at a higher position which receives the paper first, to firmly hold the same and draw it during the rotation, currently has a "furrowed" external surface provided with a plurality of parallel circular bands made of high friction material.
  • Such bands are separated from each other by other parallel circular bands made of other material, generally low friction material.
  • stop and breaking means of the same which cooperate with the abovementioned "furrowed" upper winding roller on which the paper is wound.
  • stop means cooperate in breaking the paper by exerting pressure against the "furrowed" surface of the roller.
  • they are provided with a plurality of parallel cavities separated from each other by parallel portions with an outwards projecting profile.
  • the projecting parallel portions are arranged in such a manner to operate against the upper roller at the parallel circular bands of material made of non-friction material while the remaining circular bands with high friction of the same roller are provided at the abovementioned parallel cavities.
  • the objective of the present invention is that of providing a device capable of overcoming the abovementioned drawbacks of the known art in an extremely simple, inexpensive and particularly functional manner.
  • Another objective is that of providing an improved rewinding machine for rewinding and forming a paper roll, capable of reducing the period of time required during the braking step which leads to ripping the paper.
  • Still another objective is that of providing an improved rewinding machine for rewinding and forming a paper roll, capable of ensuring better winding of the tip of the ripped paper onto a related new core.
  • Still another objective is that of providing an improved rewinding machine for rewinding and forming a paper roll, capable of ensuring ripping also the types of paper of greater thickness/resistance with respect to ones used currently.
  • FIG 1 shown is an improved rewinding machine for rewinding and forming a paper roll, in particular paper subsequently used as toilet paper, kitchen rolls, and the like, in which shown is the arrangement for rewinding and winding a paper roll according to the invention.
  • the supplied paper is of the type made of one or more layers combined to each other, once unrolled from their respective rolls, not shown.
  • This paper as layer is delivered from a large roll (not shown) and it should be wound on a tubular core 12.
  • Such machine as shown in figure 1 , comprises three rollers 16, 17 and 18 with axis parallel to each other and perpendicular to the direction of advancement of the paper, not shown, generally supplied vertically above the roller 16.
  • the latter said "pressure roller”, keeps a given pressure on the roll or log being formed, ensuring its proper winding and it is supported on opposite ends by at least a pair of arms 22, one of which is schematically shown in figure 1 alongside a related pin 23.
  • roller 18 can be subjected to pressure control through a sensor or a similar element (not shown).
  • the machine comprises an introduction group 13 which introduces the cores 12 one after the other into a channel 24 provided beneath the upper roller 16 where proper winding of the paper on each core 12 is controlled to provide a finished roll, of a preset size, usually referred to as a "log".
  • the channel 24 is provided with curved elements or cradles 25, arranged adjacent to each other, only one of which is shown, adapted to be at least partially inserted through their ends into grooves 26 provided on the external surface of the of the lower roller 17.
  • the lower roller 17 could also be smooth and such curved elements are laid against its surface in this case.
  • the machine comprises a step group 120 of the paper itself, which cooperates with at least one first surface portion 16', 16" of the upper roller 16 on which it operates rotating around a pin 128 parallel to the axis of the roller 16.
  • the stop group 120 which blocks the paper operating on the portions 16', 16" of roller 16, intervenes on the paper wound and moved forward on the roller 16.
  • the stop group 120 can be positioned upstream of the channel 24, as shown in figure 1 , or alternatively inside the same channel 24, as shown in figure 3 .
  • the stop group 120 comprises at least one stop element 120', 120" of the paper moved forward wound on the roller 16.
  • Each stop element 120', 120" is provided with an arm 132', 132" rotating around the abovementioned pin 128 and with a free end made up of a smooth surface 133', 133''.
  • smooth surface 133', 133" operates on the related at least one first surface portion 16', 16" of the upper roller 16 which, according to the invention, is smooth and provided with a plurality of air suctioning holes 101 for holding the paper wound onto the upper roller 16 itself.
  • contact between the roller 16 and the related stop group 120 is a contact between two smooth surfaces and not, as currently known, between two furrowed surfaces.
  • the rewinding machine 10 subject of the present invention is implemented with enhanced continuity in the winding process alongside the synchronised highly accurate breaking of the paper in proximity to the perforation.
  • the machine 10 allows ripping also the types of papers with much more trickiness and/or resistance to ripping with respect to the ones commonly used currently.
  • the machine comprises a plurality of the abovementioned stop elements 120', 120" arranged in series one after the other and separated from each other by an interspace.
  • the surface of the upper roller 16 possibly further comprises at least one second surface portion 116', 116" provided with friction material.
  • such friction material present in this at least one second surface portion 116', 116'' of the upper roller 16 is preferably tungsten carbide while the at least first smooth surface portion 16' , 16'' on which the stop group 120 operates with the related smooth surfaces 133', 133" is preferably made of aluminium.
  • the at least one first surface portion 16' 16'' of the upper roller 16, or the entire surface of the roller 16 in the absence of the at least one surface second portion 116' 116'' made of friction material can be made of iron.
  • the abovementioned smooth surfaces 133', 133" are preferably made of vulcanised rubber.
  • the introduction group 13 comprises a pusher conveyor 15, upstream of the three rollers 16, 17, 18 for the introduction of the cores 12 into the channel 24 one after the other, and a rotating pusher 35 adapted to move the cores 12 forward along the channel 24.
  • the upper roller 16 has at least a suctioning function and it comprises a plurality of longitudinal channels 100 arranged as a circular ring in proximity to its cylindrical surface and arranged connected to the external by means of the already mentioned plurality of holes 101.
  • the machine lastly comprises at least a pair of circular section-shaped sliding suctioning elements 102 arranged in axis with respect to the roller 16, fixed and facing the opposite tips adapted to trigger the air suctioning through the channels 100 comprised between them.
  • the suctioning of the air through such channels 100 which can be continuous or suitably synchronised with the operation of the rewinding machine, thus involves only one portion of the upper rotating roller 16 where the suctioning sliding elements 102 are provided.
  • the machine further comprises, for example, chains 14 parallel to each other for moving the cores forward up to the channel 24, only one of which is shown.
  • the improved rewinding machine for rewinding and forming a paper roll provides for the forming of a finished roll winding the paper supplied by the machine on a core 12.
  • the machine Upon completion of the winding process, the machine provides for ripping the paper, ejecting the finished roll and winding the tip of the ripped paper on a new core.
  • the ripping of the paper occurs through the contact of at least one stop element 120', 120", and in particular of one of its peripheral smooth surfaces 133', 133", against portions 16', 16", smooth too, of an upper winding roller 16 on which the paper proceeds.
  • Adherence of the paper against the roller 16 is ensured by the fact that the roller 16 is at least of the suctioning type.
  • portions 116', 116'' provided with friction material arranged at the spaces between a stop element 120', 120" and the subsequent one to ensure further holding of the paper against the roller 16.
  • the machine advantageously allows ripping also the types of papers with much more trickiness and/or resistance to ripping with respect to the ones used currently.
  • an improved rewinding machine for rewinding and forming a paper roll according to the present invention attains the objectives outlined beforehand.
