Definitions

  • the present invention relates to machines for treating and in particular 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 in pairs. , the two frames delimiting an enclosure in which a treatment fluid circulates.
  • patent FR-A-2,413,141 relates to the arrangement of the inlet and outlet ends of such a machine and describes the presence at each of these ends of at least one flap articulated around an axis parallel to the plane of the sheet and transverse with respect to the direction of movement of this sheet, this flap being able to be brought into the high position or into the low position by means of jacks, depending on whether the machine may or may not be crossed by a sheet or other product to be treated.
  • the object of this invention is to provide an arrangement of the inlet and outlet ends of a sheet processing machine, of the type defined above, which does not have these drawbacks and which ensures good sealing and good resistance to pressure of the coolant while being of lighter and more economical construction, less bulky and of a nature to allow an adaptation according to the width of the product to be treated.
  • Also known from document DE-A-2 030 265 is a machine of more rudimentary design consisting of a bell made in three parts, a central part and two end parts, the central part of which is connected to an inlet. cooling water.
  • This bell is open along its two lateral edges and is not completed by cooling means which made it possible to act on the underside of the product to be treated. During cooling, the fluid projected by the water inlet freely escapes along the side edges of the bell and is therefore not confined or maintained in the machine itself.
  • the subject of the invention is a machine for treating sheets or the like comprising an upper frame and a lower frame delimiting an enclosure in which a treatment fluid is contained and can circulate, as well as a device for closing off the ends of inlet and outlet of this machine comprising at each end, a flap carried by one of the frames and actuating means of this flap, characterized in that said frame comprises guide means allowing movement of the or each flap in a direction roughly perpendicular to the plane of the sheet passing through the machine, and in that the free edge of the or each flap cooperates with a transverse groove of the other frame, in order to close the corresponding end in a substantially sealed manner of the machine.
  • 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 to spend in the machine and the curved portions 12 b, 22 "around the drive and guide rollers 13, 23.
  • the metal sheaths delimit a chamber in which may circulate a cooling liquid, 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 side walls 11 of the upper frame are connected by a beam 30 which in the example shown has a box structure, and whose horizontal upper wall 31 has an extension 32 directed towards the interior of the machine.
  • the closure device In the space between this transverse beam and the adjacent envelope 12 ! delimiting the enclosure for the cooling fluid is arranged the closure device according to the invention.
  • This device mainly comprises several rigid shutters juxtaposed 33 to 37 (Fig. 2) having for example a thickness of between 10 and 30 mm.
  • the central flap 35 extends on either side of the longitudinal plane of symmetry of the machine, represented by the line XX. For a machine 4.20 m wide, the central flap can for example have a width of 2 m and the other four flaps a width of 0.55 m.
  • the number and the width of the shutters are chosen at will.
  • the horizontal end wall of the upper frame has a transverse slot 38 , spanning the entire width of the machine.
  • a transverse slot 38 On both sides of this slot are fixed two parallel plates 39 arranged vertically and which define a housing in which the flaps can be retracted.
  • This housing is sealed in its upper part by a cover 40 constituted by a simple plate fixed on the two vertical walls 39.
  • the horizontal wall 12 On either side of the slot 38, the horizontal wall 12 "has seals 41 which may be constituted by bronze wear pads or by fittings made of a material having a low coefficient of friction
  • the flaps carry at their upper part rods 42 which pass tightly through the cover 41, for example through cable glands 43, and are themselves articulated at their upper end on actuator rods 44, the bodies 45 of which are fixed to the wall 32.
  • two or more rods 42 can be provided for each flap, connected at their upper part to horizontal lifting beams on which the cylinder rods 44 are articulated.
  • the lower free edge 46 of the flaps has a bevel shape, cooperating with a groove 47 of complementary shape provided in the horizontal end wall 22a of the lower frame.
  • the various juxtaposed flaps have along their adjacent edges complementary profiles, a number of variants of which are shown in FIGS. 2 to 5.
  • these profiles are simply formed by recesses 48 in a broken line at two right angles, the shape of which appears clearly in this FIG. 2.
  • these profiles 49 have a V shape, with a re-entrant and projecting angle respectively. It should be noted that in this case the orientation of the Vs is such that any leaks are directed towards the sides of the machine.
  • the sockets 50 at the adjacent edges of the flaps are of the tongue and groove type.
  • the complementary profiles 51 have a rounded shape, respectively concave and convex. Again the orientation is such that any leaks are directed to the sides of the machine. Similar profiles, complementary to those of the flaps, can also be provided on the two side walls 11 of the frame, or alternatively sealing gaskets in contact with the vertical edges of the end flaps.
  • FIG. 6 Another alternative embodiment has been shown in FIG. 6 about the lower free edge of the flaps and the groove provided in the lower frame.
  • this free edge 52 can simply comprise two lateral chamfers 53, while the groove 54 has a general profile of rectangular shape, the two upper edges of which are widened by means of chan brakes 55.
  • this closure device is carried by the upper frame. However, one can consider providing it on the lower frame.
