Definitions

  • the present invention relates to machines for processing and in particular for cooling sheets, or other similar products, of the type comprising a lower frame and an upper frame in which are mounted sets of rollers for driving and guiding the sheet, operating by pairs, the two frames delimiting an enclosure in which a treatment fluid circulates.
  • Such a machine is described in particular in French patent n ° 73 10 710 of March 26, 1973 and in French patents n ° 77 39 833, 77 39 834, 77 39 835, 77 39 836 filed on December 30, 1977.
  • the object of this invention is to propose an improvement which makes it possible to solve this problem and to make these seals much more accessible.
  • the subject of the invention is a sealing device for a machine for treating sheets or the like, this machine comprising an upper frame and a lower frame delimiting an enclosure in which a treatment fluid can circulate, these frames bearing sets of drive and guide rollers operating in pairs, and comprising in the vicinity of the inlet and outlet ends at least one seal fitted by a wall of the enclosure and cooperating with an adjacent roller.
  • an insert removably secured on the former area - térieure of the vessel wall and partially housed in a slot in said wall and extending over the entire width of the machine , said insert comprising a seal intended to cooperate with the roller.
  • FIG. 1 the inlet end of a plate cooling machine comprising an upper frame 10 and a lower frame 20.
  • Each frame has side walls 11, 21 connected by metal envelopes 12, 22 having roughly flat parts 12a, 22a parallel to the sheet to be passed through the machine and curved parts 12b, 22b which surround the drive rollers. and guide 13, 23.
  • the metal envelopes delimit an enclosure E in which a coolant can circulate, the enclosure being for this purpose connected to inlet and outlet conduits for this liquid, the conduits 14, 24 shown in the drawing being in this case the outlet conduits.
  • the casing 12b comprises roughly in the horizontal diametral plane of the end roller 13 a slot 30 which extends over the entire width of the machine and in which is received an added element constituted by a bar 31 metallic or plastic material removably attached and with a waterproof seal on the casing (Fig. 2). This attachment is accessible from outside the machine.
  • This added element which, in the example shown has a T-shaped cross section, carries along its edge disposed inside the envelope a seal consisting of a hollow body or inflatable tube 32 made of a material elastomer and carrying a wear material 33 with a low coefficient of friction.
  • This wear material can be "Teflon" or any other suitable material.
  • the hollow body or flange 32 has a base 34 which ensures its fixing in a groove 35 of the bar. In the free state, the flange has a flattened shape, as shown in solid lines in FIG. 2, and it is connected by a conduit 36 to a source of pressurized fluid, air or liquid, making it possible to give it the expanded form shown in phantom.
  • Seals 37 are also provided between the bar 31 and the wall 12b of the machine.
  • This bar can of course be produced in several sections.
  • the slot 40 formed in the wall 12b has a smaller height than in the previous example and the sealing device comprises a housing or cover 41 removably attached and sealed to shell 12 b and carrying a hollow body or inflatable tube 42 similar to that shown in FIG. 2.
  • This flange is therefore placed outside the envelope and carries a blade or bar 43 of relatively small thickness which extends through the slot 40 and projects inside this envelope.
  • This blade may have at its end a lining 44 made of a material with a low coefficient of friction, such as "Teflon" or other similar material.
  • FIG. 4 comprises, housed in a slot 50 of the upper frame, a body 51 of stainless steel completed by a closure plate 52.
  • This body is removably attached to the machine and extends over the entire width of the latter, parallel to the axis of the roller.
  • a seal carrier 53 in bronze is slidably mounted in the body 51, 52 and carries a seal 54 intended to come into contact with the adjacent roller.
  • the seal carrier has a T shape and is biased towards the roller by means of an inflatable tube 55, against two elastic return rods 56.
  • the hollow body can have an expanded form in the free state and for it to be retracted by being connected to a source of vacuum.
