Definitions

  • the invention relates to a machine for the mechanical treatment of paper especially for embossing and assembling two continuous strips of absorbent paper such as cellulose wadding, comprising means support for a roll as well as a method for replacing rollers of such a machine.
  • the invention relates more particularly to a machine for mechanical paper processing, of the type in which two strips of paper each pass between two cylindrical embossing rollers, one smooth rubber coating, the other engraved, for example steel.
  • Both engraved cylinders have parallel transverse axes, each mounted at rotation about their axis between two uprights of the machine, and are arranged tangentially against each other,
  • the machine is of the type in which a first of the engraved rollers is rotatably mounted on a cradle which is likely to pivot relative to a fixed frame of the machine on which is rotatably mounted the second engraved roller, and of the type in which each roller engraved is rotatably mounted by means of bearing bodies which are arranged at each end of the roller and which are fixed in housings correspondents fitted in the uprights of the fixed frame and the swivel cradle.
  • FIG. 1 a part of a machine for mechanical treatment of known type paper. It has two rollers cylindrical engraved, each mounted rotating around a transverse axis horizontal between two vertical uprights of the machine which each extend in planes perpendicular to the axes of the rollers. Each of the rollers has a central shaft, one end of which is mounted via a bearing housing in a housing of the corresponding amount.
  • the bearing body can for example ensure both the guiding in rotation of the roller and its immobilization in the transverse direction. It can also carry the means drive in rotation of the roller and / or means for precise adjustment of the position of the axis of the roller in order to control in particular the spacing of the two engraved rollers or their relative axial position.
  • the object of the invention is to propose a new design for a machine for the mechanical treatment of paper which allows to carry out a faster change of engraved rollers, in particular for the purpose of limit the duration of this replacement, during which time the production of the machine is of course stopped.
  • the invention provides a machine of the type described previously, characterized in that the bearing bodies of at least one of the engraved rollers are fixed in housings which are delimited at least in part by a removable flange which, when disassembled, releases a radial opening through which the bearing housing can be released from the housing in a radial direction, and in that the cradle which carries one of the engraved rollers pivots around a transverse axis parallel to the axes of rollers between a service position, in which the two rollers are tangents, and a clear position for dismantling the engraved rollers,
  • FIG. 1 schematically illustrates part of a machine for the mechanical processing of paper, more particularly a part of the machine intended to ensure the embossing and the association of two strips of paper which pass between two engraved cylindrical rollers 10, 12, which are each mounted for rotation about an axis, respectively A1, A2, between vertical uprights 14, 16 which are arranged in planes perpendicular to the axes A1, A2, at the two axial ends of the rollers 10, 12.
  • the two axes A1, A2 are arranged in the same horizontal plane and the uprights 14, 16 are substantially vertical.
  • the machine also includes rollers with rubber coating 18, 20 which press the strip of paper against the engraved rollers 10, 12. They are also rotatably mounted around two transverse axes horizontal A3, A4, and are arranged respectively below and above the associated engraved roller 10, 12.
  • a first 10 of the engraved rollers and the roller associated rubber coating 18 are mounted on uprights 14 which are articulated around a transverse horizontal axis A5 relative to a frame 22 of the machine so as to be able to disengage the first roller 10 from the second 12.
  • the two mobile uprights 14 on which the first roller is mounted 10 thus form a cradle 24 which is capable of pivoting about the axis A5 relative to the frame 22 of the machine from a service position (illustrated in the Figure 1) in an open position.
  • the fixed uprights 16 on which the second 12 is mounted of the two engraved rollers are integral with the frame 22 of which they are part integral.
  • the coated roller in rubber 18 associated with the first roller 10 is not mounted directly on the cradle 24 but it is integral with the latter by means of two arms 26 which, themselves, are mounted tilting relative to the uprights 14 around an axis horizontal transverse A6 between a service position, illustrated in Figure 1, and an open position in which the rubber-coated roller 18 is not no longer in contact with the first engraved roller 10.
  • Each arm 26 is controlled by tilting around its axis A6 by a jack 28.
  • each of the two rollers engraved 10, 12 is mounted between the two corresponding uprights 14, 16 by via bearing body 30 which can, for example, provide guidance in rotation, the axial immobilization, the rotational drive, and / or the precise relative positioning of each of the rollers 10, 12 relative to the corresponding amounts 14, 16
  • the bearing bodies 30 are themselves in corresponding housings fitted in the uprights 14, 16.
  • FIG. 2 illustrates a machine for the mechanical treatment of paper in accordance with the teachings of the invention.
  • the position of the axis A5 of pivoting of the cradle 24 has been modified to allow greater opening angle of the cradle 24 towards its released position. So the axis of pivoting A5 has been brought closer to the axis A1 of the first engraved roller 10 which is carried by the cradle 24.
  • the uprights 16 linked to the frame 22 have been modified by the addition of a fixed plate.
  • the pivot axis A5 of the cradle 24 is arranged substantially in a vertical plane passing through the axis A1 of the first roller 10 and below it.
  • An actuator cylinder 29 has been mounted between the fixed frame and the cradle. This cylinder has the function of ensuring the pivoting of the cradle between the positions of service and clear.
  • the uprights 14, 16 of the machine have been modified in such a way so that the housings in which are received the bearing bodies which support each of the engraved rollers 10, 12 are partially delimited by removable flanges 36.
  • the bearing body 30 forms an assembly which is axially crossed by the axial ends of a central shaft of each of the two rollers 10, 12.
  • a part at least 40 of the bearings 30 is engaged in a housing 42 arranged in the side while a second part 42 of the bearing 30 may for example protrude transversely to outside compared to the amount considered.
  • part 40 of the bearing body 30 which is received in the housing 42 is cylindrical so that the housing 42 has a complementary cylindrical shape
  • One half of the cylinder is delimited in the corresponding flank, while the other half of the cylinder is delimited by a cylindrical arc face 46 of the removable flange correspondent 36.
  • the plane of connection of the two surfaces in arc of cylinder which delimit the housing 42 is vertical so that, in this case, the flange transverse can be dismantled radially in a direction substantially horizontal with respect to the axis A1, A2 of the roll 10, 12 concerned.
  • the housing 42 When the flange 36 is removed, the housing 42 thus has a opening which is oriented radially, which extends transversely over the whole the thickness of the upright, and through which the bearing body 30 can be engaged or released in this radial direction.
  • the two engraved rollers 10, 12 are thus mounted so that they can be radially disengaged with their bearing bodies 30 thanks to the removable flanges 36.
  • the jacks 28 are kept depressurized and the cylinder 29 is put into action to tilt the cradle around its axis A5.
  • the cradle 24 is brought back by the jacks 29 to its position service so that the housings 42 of the cradle 24 are arranged facing each other of the second roller 20.
  • each housing 42 which is normally closed by the flange 36, is defined in particular by a guide edge.
  • the guide edges of the openings of two housings facing each other are arranged substantially parallel to one another when the flanges 36 are removed.
  • the cradle 24 having been previously returned to the position of service as shown in figure 5 it is possible to move horizontally the second roller 12 with its bearing bodies 30 in the direction of housings 42 arranged in the mobile uprights 14 of the cradle 24.
  • the cradle 24 bringing the cradle 24 towards its clear position, it is particularly easy to handle the second roller 12 with its bearing bodies 30 to remove them from the machine.
  • This particularly delicate phase can therefore be done in time mask.
