Definitions

  • the invention relates to a winding device for spirally winding a three-dimensional padding material which has been produced by a pad forming machine from a web-shaped starting material, in particular a roll or a Leporello stack, for example made of paper.
  • the invention also relates to a cushion winding system comprising a winding device and a cushioning conversion machine for producing the cushioning material from a sheet-like starting material.
  • Machines for producing a three-dimensional cushioning material from a sheet-like starting material, for example made of paper, are known, for example, from DE 10 2008 039 617 Ai or EP 2 711 168 Bi.
  • a hollow paper web roll is provided as the starting material, from the inside of which the paper web is drawn in by spiraling in the form of a spiral tube by a motorized conveying and shaping device.
  • the conveying and forming rollers of the forming device bring when conveying the paper web through their engagement area a mountain valley profile in the spiral-like paper web tube. In this way they produce a stable three-dimensional tubular padding material.
  • EP 2 711 168 Bi describes a cushioning conversion machine whose starting material may be rolled up or provided in the form of a fanfold stack. From the top of the stack or the outside of the roll, the paper web is fed to the forming machine. The paper web has two longitudinal edges extending in the web direction and an intermediate region extending therebetween which extends parallel to the longitudinal edges. The right and left longitudinal edge strips are at least partially turned over or rolled over the central region, so that extending in the web direction Crumb cavity forms. At least a portion of the central region is secured along a web-extending deformation zone.
  • an embossing roller pair For forming and fixing the web sections, an embossing roller pair is used, which introduces a hill-valley profile in the central region and the overlying parts of the side edges to fasten them together. Downstream of the gear pair may be provided a cutter which separates individual padding pads from the three-dimensional padding tube.
  • Three-dimensional upholstery material hoses or cushions of different lengths can be produced with these proven upholstery conversion machines.
  • it is desired to cover large areas with cushioning material.
  • a container for example cartons, a box, a mesh basket or the like
  • three-dimensional cushioning material for transporting a heavy or delicate conveyed material on the cushioning material.
  • several cushion pillows can be inserted parallel to each other in the carton to cover the bottom surface.
  • a long cushion pad may be created which will be tied into a spiral screw to cover the cardboard bottom. The use of such bolsters reduces the number of pad units to be inserted and thereby the number of actions to be performed by the packer, and thus the duration of the packing operation, which can result in greater throughput for the same amount of time.
  • WO 99/21702 A2 discloses a cushioning conversion machine in combination with a winding device.
  • the cushioning conversion device comprises a converting device for converting a sheet-like stock material into a three-dimensional cushioning material strip having tubular or pillow-like regions and an embossed central region.
  • the cushioning conversion device discharges the cushioning material strip at a discharge opening in the horizontal direction.
  • a beak-like guide is provided which guides the padding material strip horizontally up to a winding device.
  • the winding device is equipped with a motor-driven shaft on which a turntable is provided, starting from which two parallel, cylindrical drivers extend.
  • the cylindrical rods are like the shaft horizontal with a horizontal orientation transverse to the horizontal conveying path of
  • Padding material strip passed between the drivers.
  • the drivers entrain the dunnage strip as it rotates, wrapping the dunnage strip into a spiral padding screw.
  • Padding material worm to provide space, the beak-like leadership is increasingly spread and can remain in tangential contact with the cushion material screw.
  • the padding material spiral When the padding material spiral has reached a desired size, it can be separated from the starting material and removed from the winding device. It has been found that this winding device can achieve practically no time saving and no increase in the efficiency of the packing operations compared with the use of a quick cushioning device described above. This is due in particular to the complicated handling of the winding device.
  • the inner threads which are tightly wrapped around the dogs may adhere to them as a user pulls on the outer threads. The user then pulls the outer turns off the inner and the worm unrolls.
  • the winder can always wind only one worm, which generally will not have an optimal fit to the surface to be covered, since cartons generally have square or rectangular but non-circular bottom surfaces.
  • the padding material can be deformed by the user or several screws must be placed side by side on a cardboard tray. Afterwards, the user must wait for the winder after inserting a cushioning material worm into a carton until the winder has wound the next worm. More quickly, the user could load the known and commonly used elongate padding material pads, which are produced at high speed by Applicant's above-mentioned pad forming machines, into the carton.
  • the packing personnel may only approach the winding machine, if this is in a safe disabled state, because otherwise a significant risk of injury from the moving parts, ie in particular the scissors-like leadership and fast turning driver, would go out.
  • the winding device must therefore constantly on and again be turned off, which further reduces the amount of produced cushion volume per time.
  • a winding apparatus for spirally winding a three-dimensional cushioning material made by a cushioning converting machine from a sheet-like starting material, in particular a roll or a Leporello stack, for example made of paper.
