Definitions

  • the invention relates to an adjustable shutter for a linear dispenser, more particularly intended for a product dispenser comprising a row of dispensing orifices, said shutter being housed inside the dispenser.
  • Distributors of products which are in the form of ramps of varying length and into which the product to be dispensed solid or fluid is injected through a longitudinal row of orifices provided in a wall of the dispenser.
  • document DE-A-31 46 656 discloses a device for cooling laminated sheet metal strips comprising means for selectively blocking outlets for cooling water to adapt the length of the distribution zone of water across the width of the strip to be cooled.
  • the invention aims to produce an adjustable shutter, adaptable to a sprayer or distributor comprising a chamber receiving at one of its ends the product to be sprayed, said product being distributed through at least one row of orifices provided in a wall of the room.
  • the adjustable shutter according to the invention is remarkable in that it consists of at least one drum, with an axis parallel to the slot or to the row of orifices of the dispenser, on the surface of which is fixed a sealing strip having at least one helical edge, said strip being capable by its helical edge of closing off at least part of the orifices of the dispenser by rotation of the drum carrying it.
  • Figure 1 is a schematic view of the shutter according to the invention.
  • Figure 2 is a partial sectional view of the shutter according to an exemplary embodiment of the invention.
  • Figure 3 is a front view of the shutter rotation control device.
  • Figure 4 is a sectional view along IV-IV of Figure 2.
  • FIG. 5 is a sectional view along V-V of FIG. 2.
  • Figure 6 is a top view of the shutter.
  • Figure 7 shows, reduced to the same cross section, the winding angle of the sealing strip.
  • the adjustable shutter in the invention is more particularly intended for equipping a flat jet sprayer 2 comprising, for example at its upper part, a water box 3 supplied at one of its ends. 4, comprising in its upper wall 5, a slot or a row of orifices 6 (FIG. 2).
  • a flat jet sprayer 2 comprising, for example at its upper part, a water box 3 supplied at one of its ends. 4, comprising in its upper wall 5, a slot or a row of orifices 6 (FIG. 2).
  • These orifices allow the water to flow through a guiding device such as tubes, towards a slot forming, with pressurized air outlets, a spray head 7.
  • the outlets are supplied via ducts air 8 receiving at one of their ends 9 the air under pressure.
  • the shutter 1 is placed inside the water box 3 and parallel to the row of orifices 6.
  • the shutter in the example of use envisaged, must symmetrically limit the length of distribution of the cooling water. Indeed, the sheet to be treated, the width of which can vary from 1.50 to 5 m, is always centered relative to the middle of the sprayers whatever its width.
  • the shutter is in the form of at least three elements: two elements end 10 and 11 comprising shutter means and a central element 12 or connecting shaft simply ensuring the transmission of movement between the two extreme elements.
  • an adjustment device 13 allowing the choice of the length of distribution of the water as a function of the width of the sheet to be treated.
  • FIG. 2 is a detailed partial view, in section, of the adjusting device 13 of the drum 10 and of its coupling with the connecting shaft 12 to the second drum 11.
  • the drums 10 and 11 are held in cages 14 ( Figures 2 and 4) which are formed, according to the embodiment, of a lower beam 15 at the ends of which are fixed support parts 16, 17 provided with slides 18 , in which the bearings 19, 20 of the pins 21, 22 of the drums 10, 11 are capable of sliding vertically.
  • the support parts 16, 17 bear on the side opposite to the beam, means of attachment 23 to the wall 5 of the water box 3.
  • spacers 24 are provided between the support parts 16, 17 to reinforce the cage 14.
  • the cage 14 is positioned so that the geometric axis of the drum is parallel to the axis of the row of orifices 6 provided in the wall 5 of the water box 3.
  • the drum carries on its surface a sealing strip 25 having at least one helical edge which, by rotation of the drum and bringing the strip into contact with the wall 5, is capable of closing at least part of the orifices 6 of the dispenser. .
  • the other edge of said strip is parallel to a generator of the drum.
  • the seal between the strip 25 and the wall carrying the orifices to be closed is obtained by pressure using a pusher member acting on the drum to move it in the plane of the axes of the orifices.
  • the beam 15 of the cages carries in the plane defined by the axis of the drum and the axis of the row of orifices, the pusher member 26 consisting of an inflatable bead. After adjustable the shutter width, the bead is inflated and comes to press according to a generator of the drum which moves, thanks to the sliding bearings, towards the wall 5 by firmly applying the strip against the orifices.
  • the sealing strip 25 has a constant width from one end to the other and is fixed to the wall of the drum according to a helix.
  • the strip allows the obturation of a determined number of orifices which delimits a obturation zone of determined width.
  • This closure zone can be moved by rotation of the drum over almost the entire length occupied by the drum.
  • a rotation control device 13 shown from the front in FIG. 3.
  • This device essentially comprises an index button 27 moving in front of a marking dial 28 on which are also provided inflation control means and deflation of the bead 26.
  • the axis 29 of the button 27 is coupled to the pin 21 of the drum 10 by means of an Oldham seal 30 which allows the displacement of the axis of the drum relative to the axis of the button.
  • the Oldham seal being a conventional device will not further described.
  • the coupling 31 of the journal provided at the other end of the drum with the connecting shaft 12 is constituted, as known, by a flexible joint 32.
  • the other end of the connecting shaft 12 is coupled to the drum 11 by a flexible seal similar to the seal 32.
  • the sealing strips 25 are fixed symmetrically on the drums 10 and 11 (FIG. 6).
  • FIG. 7 shows, brought back on the same transverse plane of the drum 10, the position of the ends of the sealing strip 25.
  • the winding angle of the strip has been taken to be approximately 99 ° 5 for a roll length of 1.90 m.
  • the shutter width is of the order of 700 mm.
  • the arrow, traced on figure 6, indicates the direction in which it is necessary to turn the button 27 therefore the roller to decrease the spraying width.
  • the increase in this width is obviously obtained by a rotation in the opposite direction.
  • the adjustment of the spray width is made deflated bead 26, that is to say, when the drums 10 and 11 are in a low position in their cages. This procedure eliminates the significant friction that could occur during adjustments and allows a better seal between the sealing strip and the area to be closed.
  • the invention is not limited to a shutter for a laminar jet sprayer, but such a shutter can be used in any dispenser of fluids or pulverulent having dispensing orifices or slots to be closed so as to adjust the dispensing width.
