Definitions

  • the present invention relates to a deflector or chute, for orienting and / or channeling a jet of products possibly propelled by an ejection system.
  • a deflector may consist of a simple screen inclined relative to the direction of the jet of products to be guided; this screen being bordered by sides which may converge from upstream to downstream.
  • the deflection of the jet can, when it is significant, be carried out by means of several juxtaposed screens bordered by flanks; it is thus possible to carry out a change of direction of the jet of products, of the order of 90 °.
  • the deflector then consists of several troughs hinged together so as to pivot at an angle chosen by the user.
  • a deflector of this type is described in particular in document US-A-2,750,235.
  • the deflection angle is usually set manually; it requires operator intervention. It is also frequent that this adjustment changes over time, sometimes very quickly, if the pressure of the products ejected on the dorsal strip of the deflector is high.
  • Document CH-A-239 895 also discloses a deflector provided with means which make it possible to remotely adjust the angle of deflection of the jet.
  • This deflector consists of a monolithic dorsal strip which moves between fixed lateral flanks. The curvature of the back band is adjusted by means of a jack interposed between the chassis and the end of this band.
  • the object of the present invention is to remedy these drawbacks. It offers a deflector whose design greatly simplifies its manufacture and its shaping.
  • the arc-shaped deflector comprises a deformable monolithic dorsal strip provided with lateral flanks made up of plates which overlap like scales.
  • the deflector in the form of an arc, comprises a monolithic, deformable dorsal strip provided with lateral flanks, and means which make it possible to deform said dorsal strip in order to vary the curvature of the arc of said back band.
  • the dorsal strip and the lateral flanks are in one piece and form part of the same blank suitably cut and folded.
  • the lateral flanks are slightly convergent from upstream to downstream and the plates constituting these flanks come from T-shaped cutouts, which also provides great flexibility to the dorsal strip; the upper half-branches of the tee are offset with respect to each other by a thickness corresponding substantially to the thickness of the blank, to allow the plates to be biased with respect to each other.
  • the means making it possible to modify the radius of curvature of the deflector consist, on the one hand, of at least one arm anchored, at one of its ends, on the downstream part of the deflector and articulated at the other end, on a frame integral with the support base of said deflector, and, on the other hand, at least one jack interposed between said arm and said support frame or base.
  • the deflector is deformed between maximum and minimum values of the radius of curvature of the arc by means of maximum and minimum stops.
  • the stops consist of chains connecting the scales together, which chains prevent the dislocation of said scales with respect to each other.
  • the stops consist of added lugs on the scales or obtained directly by cutting or stamping the blank.
  • the deflector 1 is disposed at the end of a product ejection system, shown in the form of a pipe 2.
  • the deflector 1 has a base 3 of square or rectangular section, which allows its assembly on the inlet pipe 2.
  • the deflector 1 comprises a dorsal strip 4 constituting a screen in the form of a continuous arc, in one piece.
  • This strip 4 is integral, at its upstream part, with the base 3 and it comprises, laterally, sidewalls 5, the upstream part of which is also fixed on said base 3.
  • the deflector 1 therefore has a U-shaped section.
  • the sidewalls 5 consist of a base plate 51 secured to the base 3 and of several plates 52 which overlap each other, in the form of scales, to channel and guide the jet of products without obstacles.
  • the downstream end of the sides 5 consists of a plate 53 of dimensions substantially greater than the plates 52, shaped with a rounded end.
  • the plates 52 have a substantially rectangular or trapezoidal shape. Note that the height of the sides 5 decreases from upstream to downstream, so that the dimensions of the plates 52 change from upstream to downstream.
  • the width of the plates 52 is between half and a third of the height of the sidewall 5 at the upstream part.
  • the radius of curvature of the arc formed by the dorsal strip 4 is variable and adjustable at will by simple deformation of this dorsal, from its downstream end and in particular, as shown in FIG. 1, from the end flanks 53.
  • These means for adjusting the arc of curvature of the deflector consist, in the case of FIG. 1, of the arm 6 in the shape of a stirrup, one of the ends of which, the end 7, is fixed to the plates 53 of the sidewalls 5 by means of pins 8.
  • the other end of the arms 6 is articulated on a frame 9 which is integral with the base 3 of the deflector.
  • This frame 9 consists of two flanges fixed on the base 3, on either side of the sides 5.
  • a hinge pin 10 is interposed between each flange of the frame 9 and the arms 6 of the stirrup.
  • a jack 11 is interposed between the base 3 and the arms 6. This jack 11 is articulated on a yoke 12 secured to the base 3 and a yoke 13 secured to the branch 14 which connects the ends of the two arms 6 beyond hinge pins 10 of the frame 9.
  • the joints 8 and 10 have a position, in space, which is chosen to allow a suitable deformation of the ridge 4, that is to say a deformation which allows it to retain a shape which is substantially similar to an arc of circle or ellipse.
  • stirrups and jacks can be provided to obtain the curvature of the backbone 4.
  • Figure 2 the single blank which allows the production of a monolithic deflector consisting of its ridge 4 and the sides 5.
  • This blank is cut from a metal sheet for example and whose length is chosen according to needs ejection, jet accuracy and the desired distance or length of the jet.
  • the edges 41 of this ridge converge from upstream to downstream.
  • the sides 5 consist of a first plate 51 followed by several plates 52, 6 in number in the figure and, at the downstream end, by a plate 53. These different plates are separated by cutouts 15 in the form of Tee whose main branch 151 is substantially perpendicular to the edges 41 of the backbone 4.
  • the half-branches 152 and 153 constituting the cap of the Tee 15 are located substantially on the edges 41 of the backbone 4; in fact, these branches 152 and 153 are slightly offset in parallel one relative to each other by a distance which corresponds substantially to the thickness of the blank to allow the inclination and the skewing of the plates 52 with respect to each other, so that they overlap when placing in volume of the blank. It is noted that the half-branch 152 is positioned inside the dorsal, with respect to the border 41 while the half-branch 153 is positioned outside the dorsal strip 4 with respect to this same border 41.
  • the plates 52 are linked to the back strip 4 and are folded substantially at right angles along a line 412 which forms a very small angle with the edge 41 so as to orient the plates 52 so that they can overlap with respect to one another. to others when shaping the deflector.
  • the first plate 51 is folded relative to the backbone 4 around a line 411 which corresponds to the edge 41.
  • This first plate 51 has a polygonal shape; its end edge 511 can receive a front plate, fixed by welding, not visible in the figures.
  • the end plate 53 is folded relative to the dorsal strip 4 around a line 413 which corresponds to the edge 41 of said dorsal.
  • the width D1 of the T-shaped cutouts 15 corresponds substantially to three quarters of the width D2 of the plates 52, so as to retain great flexibility of the dorsal strip 4, for folding.
  • these plates 52 have a substantially rectangular or trapezoidal shape, and that their surface is decreasing from upstream to downstream.
  • the end plate 53 extends in length, over a distance which corresponds substantially to the width of two or three plates 52. It is noted that this end plate 53 comprises an edge 531 in the form of an arc of a circle intended to be welded to the edge 41 of the dorsal strip 4 so as to bend the end of the latter.
  • the end 532 of the plate 53 is formed into a rounded shape.
  • Means make it possible to limit the angular deformation of the deflector between a maximum value and a minimum value. These means also make it possible to guide the plates or scales relative to one another. They consist of lights and finger-shaped stops.
  • the first plates 51 comprise a stop
  • the plates 52 comprise both a stop and a light
  • the last downstream plates 53 each comprise a light which cooperates with the finger of the adjacent upstream plate 52.
  • the fingers can be made up of bolts or rivets, the head of which acts as a guide for the plate provided with the corresponding light, that is to say that these bolts or rivets assemble the plates with respect to one another with a degree of freedom so that they slide over each other.
  • the maximum stops 16 consist of chains which connect the plates 51, 52 and 53 together so as to limit the radius of the arc of the back band 4 to a maximum value.
  • the minimum stops 17 consist of lugs added to the plates 51, 52, 53; these pins can also be cut from the blank constituting the deflector.
  • FIG. 3 another embodiment of the means for adjusting the radius of the arc of the dorsal strip 4 has been shown.
  • the means are practically identical to those shown in FIG. 1; their layout is different.
  • the cylinder 11 is articulated on the arms 6 between their ends, that is to say between the articulations 8 and 10.
  • the articulation 10 of the arms 6 on the frame 9 is arranged further behind the deflector, due to the inclination of the frame 9.
  • the jack 11 is articulated on the frame 9.
  • the chute When the chute is shaped, that is to say when the sides 5 are positioned at right angles, it is possible to insert in the branches 152 and 153 T-shaped cutouts 15, a flexible sealant for sealing the silicone type, which closes the cutouts in question so as to avoid the passage of dust or other in this zone of the deflector.
