Definitions

  • the present invention relates to a roller for guiding a sheet by friction.
  • the present invention relates to a transport device comprising such rollers for transporting sheets by friction.
  • the present invention can for example be applied to the field of manufacturing foldable boxes from cardboard sheets, the roller then serving to guide each cardboard sheet.
  • a collapsible box can for example be a packing carton. In general, such sheets of cardboard are moved along a production line.
  • the present invention can be applied in other fields requiring the registration of objects in the form of sheet such as sheets, wooden planks, plastic plates etc.

  • the transport device of the EP1837298 is used to align a sheet that is slightly offset and / or tilted with respect to a fixed reference stopper (jogging)
  • the alignment of the sheet is sensitive to the jogging angle set by the operator. But when the jogging angle is small, the correction of the sheet position is very slow. Conversely, when the jogging angle is large, the sheet is aligned faster, but the moment the sheet is pressed against the stopper, strong mechanical stresses are generated, which can cause sheet wrinkling or premature wear. pebble.
  • the document JP2002370851 discloses a lateral registration correction mechanism for misaligned sheets of paper in a copier or printer according to the preamble of claim 1.
  • the mechanism comprises disc-shaped rollers comprising flexible segments and configured to flex axially.

  • such a roller offers greater compliance or lateral flexibility than a roller of the state of the art.
  • the or each notch defines on the roller one or more elastically deformable segments which can flex, in the axial direction, independently. Therefore, this independence of deflection makes it possible to release excessive mechanical stresses as soon as an elastically deformable segment is no longer in contact with the sheet.
  • the roller makes it possible to release the stresses six times per revolution.
  • Such a roller has lateral flexibility allowing the sheet to be aligned against a stop, so as to guarantee its registration before a treatment of the sheet, for example printing, cutting, laminating or folding-gluing.
  • the contact surface is a surface of the roller which is radially outermost, that is to say the furthest from the axis of revolution of the contact surface.
  • the axis of the cylinder forming the contact surface coincides with the axis of rotation of the roller when the roller is in the service configuration.
  • the central portion may include retaining members configured to retain the or each rotary bearing.
  • the retaining members can be formed by a rolling cage.
  • the roller is characterized in that the deformation portion of the roller comprises an outer ring and several connecting members mechanically connecting the central portion and the outer ring, at least one notch extending through the outer ring of so as to interrupt the outer crown at least once.
  • Each connecting member extends at least in a radial direction.
  • Each connecting member can also extend in another direction, for example in a tangential direction and / or in an axial direction.
  • the roller is characterized in that each connecting member substantially forms a radius for the roller.
  • the roller has openings located respectively between two consecutive connecting members. Thus, the roller has a reduced weight.
  • the deformation portion is solid.
  • the deformation portion continuously fills the space located between the central portion and the contact surface.
  • several connecting members of the roller are formed by leaf springs.
  • the roller comprises recesses located respectively between two consecutive connecting members.
  • several recesses each have a rounded shape.
  • the stresses are reduced and the life of the rollers is increased.
  • several recesses each have the overall shape of a cylinder extending parallel to an axial direction of the roller.
  • each recesses each have a triangular shape pointing substantially towards the central portion.
  • the recesses can be filled with a material more elastically deformable than the connecting members.
  • the contact surface of the roller has the overall shape of a cylinder.
  • a contact surface can have a large surface area in contact with the sheets.
  • the contact surface has the overall shape of a torus portion.
  • the number of notches in the roller is greater than or equal to two, for example equal to seven.
  • the roller makes it possible to release the stresses several times per revolution, therefore to increase the jogging angle and align the guided sheet more quickly.
  • the notches in the roller are distributed uniformly around the central portion, on the perimeter formed by the contact surface.
  • such an arrangement of the notches makes it possible to distribute the mechanical stresses on the roller.
  • the notches are distributed uniformly around the axis of rotation of the roller, when the roller is at rest.
  • At least one notch of the roller is configured so that the intersection of the notch with the contact surface forms a segment rectilinear and parallel to the axis of revolution of the contact surface.
  • the roller is easy to manufacture. It can for example be extruded or cut in water.
  • At least one notch of the roller is configured such that the intersection of the notch with the contact surface forms a segment oblique to the axis of revolution of the contact surface.

  • the discs are added to the notches and define on the roller one or more elastically deformable segments which can flex, in the axial direction, independently.
  • Such a disc roller has lateral flexibility, each disc flexing independently of each other. So this independence of deflection of the discs between them makes it possible to release too strong mechanical stresses, as soon as a disc segment, located between two notches, and elastically deformable is no longer in contact with the sheet.
