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 FR-A-2223096 and in French patents FR-A-2413139, FR-A-2413140, FR-A-2413141 and FR-A-2 413 467.
  • 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 (FR- A-2413141).
  • an attached element removably attached to the outer surface of the wall of the enclosure and partly 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 comprising roughly flat parts 12a-, 22a- parallel to the sheet metal to pass through the machine and curved parts 12 b- , 22 b- which surround the drive and guide rollers 13, 23.
  • the metal envelopes delimit an enclosure in which a coolant, 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 12 b- 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 attached element constituted by a metal or plastic bar 31 removably fixed and with a leaktight seal on the envelope (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 12 b- has a lower height than in the previous example and the sealing device comprises a casing or cover 41 removably and tightly fixed on the envelope 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 The variant of FIG. 4 comprises, housed in a slot 50 of the upper frame, in body 51 made 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 joint holder 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.
