Definitions

  • the present invention refers to an improved winding group and method for winding paper around a core to make a log.
  • rollers that cooperate to wind the log.
  • the paper moving forward on a roller is torn by suitable devices so as to define two edges of which the one downstream is called “final edge” and is wound on the finished log, whereas the one upstream is called “initial edge” and is associated with the new core being inserted into the machine.
  • timing devices make known machines very complex and difficult to make, as well as greatly slowing down the production of the logs.
  • the purpose of the present invention is to make a winding method and group for winding paper around a core to make a log capable of solving the aforementioned drawbacks of the prior art in an extremely simple, cost-effective and particularly functional manner.
  • Another purpose is to make a winding method and group for winding paper around a core to make a log in which the glue is dispensed onto the core upstream of the channel so as to allow a quick coupling with the "initial edge" of paper moving forward on the upper roller.
  • Yet another purpose is to be able to have a winding method and group for winding paper around a core to make a log in which the timing device of the core equipped with glue outside of the channel is easy to make and does not in any way slow down the production of the logs.
  • Yet another purpose is to be able to have a winding method and group for winding paper around a core to make a log in which the coupling of the initial edge with the glue is always ensured also in the presence of errors of linearity of the core and/or wearing of the components that thrust the core upstream of the channel.
  • Yet another purpose is to be able to have a winding method and group for winding paper around a core to make a log in which the "hold" of the initial edge with the glue is greater with respect to known machines.
  • Yet another purpose is to be able to have a winding method and group for winding paper around a core to make a log in which the amount of glue dispensed is less with respect to known machines.
  • a winding group for winding paper 11' around a core 11 to make a log 11" is shown with 10.
  • Such a winding group 10 comprises, in an upstream position, means for dispensing glue onto the core 11, means for transporting and introducing a succession of cores 11 equipped with glue one after the other in a channel 12 that, as can be seen in the figures, is defined at the top by an upper winding roller 14, supplied from above with the paper 11' directed towards the channel 12 itself, and at the bottom by a cradle member 13.
  • a lower winding roller 15, associated downstream of the cradle member 13, and a third oscillating roller 16 arranged above the lower winding roller 15 are also foreseen.
  • the dispenser of glue 21 onto the core upstream of the channel 12 preferably comprises means for depositing a plurality of circle arcs 21 of glue on at least one outer portion of the core 11 so as not to require a particularly precise timing of the core itself 11 upon introduction into the channel 12.
  • such a greater "hold” allows the amounts of glue 21 dispensed onto the cores 11 to be reduced.
  • This aspect is extremely advantageous since it also allows a greater margin for error to make up for the fact that the core 11 is not always linear, for the wearing of the components that thrust and time the core 11 upstream of the channel 12.
  • the group 10 can comprise means for orienting the core 11 comprising an upper abutment plane 61 that at least partially extends from the means for dispensing glue towards the channel 12 above the means for transporting and introducing the core 11 and friction elements 62, preferably knurled.
  • Such an upper abutment plane 61 and such friction elements 62 impose a controlled rotation upon the core 11 after the supply of glue 21 to arrange it in an optimal position for immediately receiving the initial edge 60 as soon as the core 11 is inserted into the channel 12.
  • the means for supplying glue on the core 11 can comprise a container 40 for the glue equipped with an opening 41 oriented upwards and associated with the means for transporting and introducing the core 11 into the channel 12.
  • a member 42 is housed that is mobile between a first position for receiving the glue by immersion and a second position for supplying the glue received onto the core 11 moving forward on the transporting and introducing means.
  • Such a mobile member comprises a plurality of free heads 43 shaped like a convex arc of circle, in which every free head 43 in the first receiving position is immersed in the glue and in the second supplying position it projects from the opening 41 towards the core 11 beyond the means 53 for transporting the core 11 as schematised in figure 1 .
  • the transportation means can comprise a plurality of chains each equipped with thrusters 51.
  • a rod member 17 is foreseen rotating or oscillating around a pin 18 and provided with a head 20 for cyclic cooperation with the upper winding roller 14 for tearing the paper 11' making direct contact with the latter against the upper winding roller 14.
  • such a head 20 of the rod member 17, at least near to the upper winding roller 16 and thus during the tearing of the paper 11', has a greater peripheral speed with respect to that of the upper winding roller 14.
  • the head 20 will roughly have a speed that is greater by about 20% with respect to the upper winding roller 14.
  • a speed ratio means that the section of paper 11' to undergo a tightening is exclusively that upstream of the head 20, unlike all rewinders currently known, thus tearing the paper 11' upstream of the head 20.
  • the rod member 17 cyclically rotates or oscillates around the pin 18 selectively firstly accelerating as it approaches the upper winding roller 14 upon contact with the paper 11' in order to definitely have a greater speed with respect to that of the upper winding roller 14.
  • the rod member 17 after the aforementioned stopping can carry out a rotation in the opposite direction, in other words going towards the upper winding roller 14.
  • the cyclic means for tearing the paper 11' are arranged upstream of the channel 12 and cooperate with means for keeping the paper 11' adhering around the upper winding roller 14 acting at least upstream of the channel 12.
  • such means for keeping the paper 11' act along both an upstream and downstream section of the cyclic tearing means to keep both the initial edge 60, upstream of the head 20, and the final edge 50 adhering around the upper winding roller 14.
  • the latter comprises a plurality of longitudinal channels 22 arranged according to a circular ring in proximity to its cylindrical outer side surface in which each of the longitudinal channels 22 is placed in communication with the outside through a plurality of holes 23.
  • suctioning shoes 24 Cooperating with such longitudinal channels 22 there is a pair of suctioning shoes 24, for example in the shape of a circular sector, arranged in axis with the roller 14 and fixed facing the opposite heads in which these suctioning shoes 24 are suitable for causing air to be sucked in through the channels 22 comprised between them from the outside towards the inside of the upper winding roller 14.
  • the aforementioned suctioning shoes 24 extend on the heads of the upper winding roller 14 both above and below the point of cyclic contact of the head 20 with the external cylindrical surface of the roller 14 itself.
  • shoes 24 extend for a sector of about 180°.
  • the suction through the shoes 24 can be continuous or suitably synchronised with the operation of the group 10 and ensures the transportation of the initial edge 60 adhering to the shell of the roller in the fraction that runs between the tearing of the paper and the insertion of the new core in the channel 12.
  • sucking surface of the upper roller 14 avoids the initial edge 60 of the paper 11' returning back and the greater speed of the head 20 avoids any accumulation of paper upstream of the head 20 itself.
  • a thruster 52 can be foreseen rotating around a pin to insert the cores 11 into the channel 12 at the unloading of the finished log 11" and at the start of a new log to be formed.
  • the means for dispensing glue onto the core according to the present invention can, for example, be associated with known rewinders in which the tearing of the paper 11' takes place both inside the channel 12 and upstream of it through a stopping element 17 that slows down the paper 11' moving forward on the roller 14, like also for other types of rewinders.
  • the glue 21 during the journey of the core 11 in the channel 12 holds the initial edge 60, which proceeds on the roller 14 thanks to the suction means, ensuring safe winding of the paper 11'.
  • Such means to cause winding can comprise means for taking the initial edge 60 away from the upper winding roller 14 arranged at the channel 12 substantially downstream of the cyclic means for tearing said paper 11' and of the suction shoes 24.
  • such means for taking away the initial edge 60 have the purpose of thrusting the initial edge 60 of the paper 11' towards the lower portion of the channel 12 promoting its firm engagement on the new core 11 equipped with glue 21 that is moving forward in the channel 12.
  • the core 11 equipped with glue and inserted in the channel 12 receives and thus, as can be seen in figure 4 , keeps the initial edge 60 of the paper 11' that, being located between the surface of the core 11 during the rotation thereof and of the cradle 13, avoids any possible deposit of glue 21 on the cradle 13 itself.
  • the means for taking the initial edge 60 away from the upper winding roller 14 can be of any type, for example of the mechanical type such as cams, but according to a preferred embodiment they comprise a pair of shoes 70 shaped like a circular sector arranged in axis with the roller 14 facing opposite heads at the channel 12 substantially downstream of the cyclic means for tearing the paper 11'.
  • Such shoes 70 are suitable for causing air to come out through the channels 22 comprised between them and thrusting the initial edge 60 of the paper 11' downwards into a position comprised between the core 11 moving forward and the cradle 13.
  • the winding group 10 for winding paper 11' around a core 11 to make a log 11" cyclically carries out the steps of:
  • the method outlined above can also comprise the step of timing the core 11 equipped with glue 21 through an upper abutment plane 61 and friction elements 62 that impart the controlled rotation of the core 11 upstream of the channel 12.
  • the winding method and group for winding paper around a core to make a log of the present invention does not require complex timing devices of the core equipped with glue outside of the channel and also the coupling of the initial edge with the glue is always ensured even in the presence of errors of linearity of the core and/or of wearing of the components that thrust the core upstream of the channel.
  • the "hold" of the initial edge with the glue is greater with respect to known machines with a smaller amount of glue.
  • the winding method and group for winding paper around a core to make a log of the present invention thus conceived can undergo numerous modifications and variants, all of which are covered by the same inventive concept; moreover, all of the details can be replaced by technically equivalent elements.
  • the materials used, as well as their sizes, can be whatever according to the technical requirements.
