Definitions

  • the invention relates to a method for the frontal packaging of a two end faces and a longitudinal axis having and stored in a roller bearing device role.
  • the invention relates to a device for the end-side packaging of a two end faces and a longitudinal axis having roller with a roller bearing device.
  • roller is generally understood to mean a winding core wound with a material web, on which a material web of any kind has been wound.
  • the material web may consist of paper, cardboard, tissue, plastic or metal, all of which must be handled in a similar manner.
  • the invention is therefore applicable to any type of material web accordingly.
  • the invention will be described below with reference to a roll of paper to be packaged, without, however, being restricted thereto.
  • paper webs After being cut to the correct width, are wound up into paper rolls. Before being transported to a consumer, they must be packed in a packing plant. For this purpose, usually a so-called inner end cover is attached to the front sides of the paper roll in each case. Thereafter, the circumference of the paper roll is wrapped with a packaging web, which usually protrudes slightly beyond the end faces. This projection is taken when wrapping or later on the front pages. Thereafter, by means of a packing press one each Outer end cover glued to each end face. For this one often uses outer end caps, which are provided with a heat-activated adhesive or plastic.
  • the outer end covers are placed with their adhesive-free point on a packing press plate, which is also referred to as a press plate, and held there, for example by means of vacuum.
  • the packing press plate is heated, the heat penetrates the outer end cover and makes the adhesive sticky.
  • the packing press plate presses the outer end cover with a very high pressure, for example in the range of 3.5 to 4 tons, against the end face of the paper roll and thus glued the outer end cover with the inner end cover and the folded supernatants of the packaging web. If so the outer end cover has been glued to the front side of the paper roll, so after a certain residence time, the packing press plate is moved back.
  • the paper rolls are transported and positioned in the region of the packing installation, in particular in the area of the packing press, by means of a so-called walking beam or by a transport chain in the axial direction.
  • This has the disadvantage that the packing press must be made pivotable in order to reach the two end faces of each paper roll.
  • the roll to be packaged is moved by the designed as a roller conveyor roller bearing device perpendicular to its longitudinal axis, that the respective end face of the roll to be packaged during their movement through the roller conveyor a PE-coated Wrapping paper web is at least temporarily pressing and then at least partially supplied in parallel aligned that the respective PE-coated kraft paper web is preferably heated immediately before or at least during its contact with the end face of the roll to be wrapped on its side touching or not touching the roll to be packed, so that due to the contact pressure of the heated and PE-coated kraft paper web by means of a pressing device, in particular a pressure roller or a pressure plate, to the front side of the roll to be packaged Ve Binding between the end face of the roll to be packaged and the front side of the roll to be packed contacting area of the heated and PE-coated kraft paper web is produced, that with continuous movement of the roll each a blank from the parallel aligned and PE-coated kraft paper web by means
  • the method according to the invention with the mentioned method steps allows continuous front-side packaging of a large number of rolls within the shortest possible packaging times, that is to say shorter cycle times.
  • the respective roll to be packed experiences through the transport described a forced operation, which is a controlled and time-reduced, that is time-minimized Movement of the role allowed. Any previous dead times, for example as a result of catching, positioning and calming the roll, are now eliminated.
  • a pivoting of the packing press plates of the previous packing presses is eliminated, which in turn ultimately saves time and reduces both the constructive and the control-technical complexity of the packaging device.
  • the role of a consistent, possibly even improved packaging quality can be packaged faster and cost-reduced.
  • the method according to the invention is distinguished by the fact that it is possible to operate with lower pressing forces, since the respective pressing device preferably generates a line force.
  • today's signs produce a surface pressure.
  • a corresponding design of the respective pressing device for example in the embodiment of a segmented pressure roller, could provide the advantage that with variable roller dimensions, certain zones of the corresponding end face are pressed more strongly than others.
  • the respective wrapping paper web is unwound and fed by a wrapping paper bobbin preferably arranged laterally of the roll transport device. Due to the design and arrangement of the supply ensures that the kraft paper web can be provided in sufficient quantity and process reliable.
  • the respective wrapping paper web is preferably on its side which contacts the roll to be packed by means of at least one heating device, for example an IR emitter, preferably at least over the height or the contour of the roll to be packed, and preferably exclusively over a length touching the roll to be packed heated away.
  • the heating device may comprise in preferred embodiments at least one IR radiator, a gas heater, a hot air device, a Schuplattenstrahler or the like.

  • the respective heated wrapping paper web is preferably pressed by means of at least one pressing device, in particular a pressure roller or a pressure plate, to the corresponding end face of the roll to be packed.
  • a pressure roller guarantees a process-reliable contact pressure of the kraft paper web with a noticeably reduced system friction.
  • the pressure roller can also be driven if necessary.
  • the respective wrapping paper web can be pressed against the corresponding front side of the roll to be packed by means of at least one heatable pressing device, in particular a heatable pressure roller or a heatable pressure plate.
  • the respective wrapping paper web is preferably heated on its side not touching the roll to be packed, preferably at least over the height or the contour of the roll to be packed, and preferably exclusively over a length touching the roll to be packed.
  • the cut-out of the respective round blank from the wrapping paper web is effected by means of at least one laser device preferably generating two laser beams, the first laser beam then being guided vertically vertically upward and then vertically downwards after reaching the upper vertex of the moving roll and wherein the second laser beam is optically guided first vertically downwards and then after reaching the lower vertex of the moving roller vertically upwards.
  • the corresponding Ronde can be produced in a simple manner, wherein the use of a Laser device also has the advantage of a non-contact and thus tear-resistant generation of the cut.
  • the trimmed kraft paper web is preferably removed via a deflection roller and then wound up into a waste bin. This type of discharge ensures a safe and reduced friction guidance of the trimmed kraft paper web in previous parallel alignment with the end face of the roll.
  • the pulley can also be driven if necessary.
