Definitions

  • the present invention relates to a filling spout and more particularly a filling spout for a weight metering machine.
  • filling spouts In order to return the jet to laminar speed when it leaves the filling spout, filling spouts are known which are fitted with a grid in the vicinity of the lower orifice of the filling spout.
  • the particles gradually close the mesh of the grid until that it is completely blocked and requires the intervention of an operator.
  • the jet leaving the filling spout has only a low stability and the impact of the jet on the surface of the liquid contained in the container generally destroys this stability and again tends to cause foaming.
  • An object of the invention is to propose a filling spout having a structure allowing a jet to be obtained particularly stable at the outlet of the filling spout and thus minimize the formation of foam in the container.
  • a filling spout comprising a tubular body having at least one portion of conical internal wall adjacent to a lower orifice of the filling spout, and a calibrating member having at least a conical calibration part disposed opposite the conical internal wall part of the tubular body and delimiting therewith an annular space of decreasing section up to the lower orifice of the spout, this annular space having a length at least equal to approximately eight times the width of the annular space taken in a radial direction at the level of the lower orifice.
  • the product to be conditioned is subjected to an acceleration which brings the jet of product to a very stable laminar regime whatever the disturbances to which the product is subjected upstream of the filling spout, and the product flows in an annular vein having no obstacle so that the device according to the invention can be used to condition liquids containing particles, in particular fruit juices containing pulp.
  • the calibration member is movable axially inside the tubular body.
  • the displacement of the calibration member makes it possible to adjust the flow rate of the filling spout while retaining the properties of acceleration of the product in the vicinity of the lower orifice of the filling spout.
  • the calibrating member is axially movable and has been shown in a closed position of the filling spout on the left half of the figure and in an open position of the filling spout on the right half of the figure.
  • the filling spout comprises a tubular body 1 equipped at its upper end with a collar 2 intended to connect it to a tube for supplying the product to be packaged.
  • the internal wall of the tubular body comprises a first cylindrical part 3 adjacent to the upper end of the tubular body followed by a series of conical parts 4 which converge towards the lower end of the filling spout, then a cylindrical part 5 followed by a conical part 6, the lower end of which coincides with the lower orifice 7 of the filling spout.
  • the internal wall of the filling spout has a recess 8 followed by a divergent conical part 9.
  • the filling spout comprises a calibrating member comprising a conical lower part 10 converging downwards and extending opposite the conical part 6 of the internal wall of the tubular body 1.
  • the conical part 10 has a conicity equal to the conical part 6 so that the opposite faces of the conical part 10 and the conical part 6 are parallel.
  • the calibrating member has a conical part 11 which diverges downwards and the upper end of which is connected by a connecting rod 12 to a closing valve 13 comprising an external surface part 14 having a conicity identical to one of the conical parts 4 of the inner wall of the tubular body 1 so as to ensure a tight closure of the filling spout when the closure valve 13 is applied to the corresponding conical part 4.
  • the connecting rod 12 comprises centering fins 15 extending radially in the part cylindrical 5 of the inner wall of the tubular body 1.
  • the centering fins 15 are mounted to slide in the cylindrical part 5.
  • the closing valve 13 is connected to a control rod 16 associated with a mechanism not shown to adjust the axial position of the sizing member in the filling spout.
  • Figure 1 illustrates the first embodiment of the invention in a closed position.
  • the closing valve 13 is then supported on the valve seat 4 while the conical part 10 is slightly spaced from the opposite conical part 6.
  • the spacing between the conical parts 6 and 10 is sufficiently small to prevent the product contained in the tubular body 1 below the closure valve 13 from flowing when the closure valve 13 is applied to its seat.
  • the lower end of the conical part 10 protrudes from the lower orifice 7 and is protected by the wall part of the tubular body 1 corresponding to the divergent conical part 9.
  • the right half of the figure illustrates the filling spout with the calibrating member in a substantially maximum open position for which the lower end of the conical part 10 coincides with the lower orifice 7.
  • the surface parts conical opposite 6 and 10 are of the same conicity and are therefore parallel to each other, the conicity of these surface parts ensures a decrease in the passage section between these surface parts, taken along planes perpendicular to the longitudinal axis of the tubular body 1.
  • the upper end of the conical part 10 is at a level higher than the upper end of the conical part 6 so that the length L according to which the annular space comprised between the surface parts 6 and 10 is decreasing coincides with the height of the conical part 6.
  • the conical part 10 of the calibrating member may have a taper slightly greater than the taper of the wall part 6 compared with the time that the difference in taper between the wall part 10 and the wall part 6 is sufficient for the section of the annular space between the conical wall parts 6 and 10 to decrease over a length L at least equal to hu it times the width l of the annular space taken in a radial direction at the level of the lower orifice 7.
  • This value is satisfactory for most products but it is not absolutely critical and can be slightly adapted according to the product to condition.
  • Figure 2 illustrates a second embodiment of the invention for which the parts having a function identical to that of Figure 1 have been referenced with the same reference numerals.
  • the tubular body 1 is designed to be mounted directly in an orifice in a lower wall of a supply tank and, for this purpose, the mounting collar 2 is arranged in the lower part of the tubular body 1 which this time has supply openings 17 through which the product to be packaged flows radially before flowing axially in the annular space comprised between the conical surface part 10 of the calibrating member and the internal wall opposite the tubular body 1.
  • the internal guide surface 5 of the tubular body 1 extends above the feed openings 17 and the calibrating member comprises a cylindrical connecting part 12 which is connected directly to the lower conical part 10.
  • the conical surface part 6 of the internal surface of the tubular body 1 is divided into an upper surface part 6.1 having a taper greater than the taper of the conical surface part 10, and a lower part 6.2 whose the taper is equal to the taper of the tapered surface portion 10 of the sizing member.
  • the lower edge of the conical part 6.1 is slightly spaced from the lower orifice 7 so that the conical part 6.2 constitutes a seat for the conical part 10 of the calibration member and, when the latter is in the low position illustrated on the left part of FIG. 2, the conical surface part 10 of the calibration member acts as a closing valve.
  • the section of the annular space between the conical surface part 10 of the calibration member and the conical surface part 6 is thus decreasing from the supply orifices 17 to the lower orifice 7 of the filling spout and an acceleration of the product is therefore obtained, as previously, favorable to the stability of the jet exiting the filling spout.
  • the lower portion 10.1 of the conical calibration portion 10 extending beyond the lower orifice 7 for a closed position of the filling spout has a taper greater than a portion immediately upstream with reference to a direction of product flow in the filling spout. It has been observed that this minimizes the risk of a drop forming when the filling spout is closed. It is desirable that the taper of the lower portion of the conical surface portion is as strong as possible, but it must be ensured that for an open position of the filling spout the section of the annular space between the surfaces 6 and 10 remains decreasing. This therefore limits in practice the taper of the lower portion of the conical calibration part 10.
  • the invention is not limited to the embodiments described and it is possible to make variant embodiments without departing from the scope of the invention.
  • the guide member it is not even necessary for the guide member to be pierced with openings since the product to be packaged penetrates into the tubular body 1 below the guide member.
