Definitions

  • the present invention relates to a method for adjusting the radial gap existing between two tools for transforming a plane support.
  • the invention relates to a transformation arrangement for a flat support, provided with two cylindrical processing tools, in a packaging production machine.
  • the invention also relates to a conversion cassette for a plane support, comprising a transformation arrangement for the plane support.
  • the invention relates to a processing unit for a flat support, equipped with a conversion cassette for the plane support.
  • the invention relates to a transformation unit for a plane support, comprising at least one transformation arrangement for the plane support.
  • the invention also relates to a packaging production machine from a flat support, comprising at least one processing unit for the plane support.
  • a packaging production machine is intended for the manufacture of boxes, which form packaging, after folding and gluing.
  • an initial planar support such as a continuous strip of cardboard, is unwound and is printed by a printing unit, consisting of printing units. The strip is then transferred to a processing unit to make plate elements, in this case boxes.
  • the processing unit comprises at least one transformation arrangement provided with two rotary cylindrical tools, positioned parallel to each other, so as to cooperate with each other.
  • the band moves between the two tools, to be transformed. Both tools rotate in opposite directions.
  • the first tool is rotatably mounted in a first and a second bearing.
  • the second tool is rotatably mounted in a third and a fourth bearing. Clamps are provided to hold firmly together and prestress the first with the third bearing, and the second with the fourth bearing.
  • the transformation arrangement is most often provided to form a cassette.
  • the cassette is slidably inserted into each of the side frames of the unit.
  • the cassette allows quick change of tools, depending on transformations of the support to be realized.
  • the packaging manufacturer has at least two cassettes. A first cassette is in the machine being produced and is adapted according to the transformation work in progress. Meanwhile, a second cassette is being edited and adjusted to suit the next transformation job. When changing the job, the operator takes out the old cassette and inserts the new cassette, minimizing machine downtime.
  • one of the arrangements or one of the cassettes is respectively a rotary cutting arrangement or a rotating cutting cassette.
  • a first cylindrical cutting tool is provided with knives, and a second cylindrical tool is smooth, and is called anvil.
  • a radial gap between the first cylindrical cutting tool and the second cylindrical tool must be very precisely adjusted.
  • the edges of the cutting tool's knives must pass as close as possible to the anvil roll, in order to make a clean cut.
  • the edges of these knives must not touch the anvil cylinder, because they would be irretrievably destroyed during rotation.
  • the material constituting the support i.e. the fibers in the case of the carton, must not appear at the cut. It is also not desirable to have dust from the cutting of the material constituting the support.
  • the advantage of adjusting the radial gap is also to compensate for the progressive wear of the cutting tool blades. Therefore, the optimal radial gap between the two rotating cylindrical tools is set in the micron.

  • the position of the crowns of the first tool can be modified laterally.
  • the lateral displacement of a crown relative to its associated crown causes a variation of the total thickness of these two crowns against each other. This has the effect of varying the difference between the first and the second tool, the radial gap is thus obtained accurately.
  • the operator first loosens the clamping elements of the bearings. Then it moves the assembly formed by the first bearing, the second bearing and the first tool, so as to separate it from the assembly formed respectively by the third bearing, the fourth bearing and the second tool. This movement is ensured by means of pivoting adjustment wedges mounted on micrometric screws.
