Abstract

The invention relates to a filling tube consisting of a tubular body (1) having a flap valve (11) and a magnetically-actuated element (4) mounted therein. The aforementioned magnetically-actuated element (4) is connected to the flap valve by means of a coupling member (18) comprising two elements (19, 21) which are connected using a link with radial play.

Description

  • The present invention relates to an electromagnetically controlled filler nozzle.
  • We know, in particular documents GB 2,086,861 and WO 01/40098 , a filling spout comprising a tubular body in which are mounted a valve extending opposite a valve seat and a magnetic actuating element associated with a coil outside the tubular body and connected to the valve by a body of axial coupling. The assembly thus formed is rigid radially so that to ensure accurate positioning of the valve relative to the valve seat so as to achieve a satisfactory seal, it is necessary not only that the valve is precisely guided coaxially to the valve seat but also that the magnetic actuating element is guided very precisely coaxially with the valve, which causes very significant manufacturing constraints. In particular, the valve and the magnetic actuating element must be rigorously coaxial with each other and when the body of the filling spout is formed of several assembled elements, it is necessary that the body elements are mounted with respect to each other in a strictly coaxial manner. These constraints result in a high manufacturing cost of the filling spout.
  • A first object of the invention is to provide a filling spout operating satisfactorily while being less expensive to manufacture than previous filling spouts.
  • A second object of the invention is to provide a filling spout that can easily be adapted to different products.
  • According to the first object of the invention there is provided a filling nozzle of the aforementioned type in which the organ coupling member comprises two elements coupled in a connection comprising a radial clearance. The control function exerted by the magnetic actuating element is thus dissociated from the shutter function performed by the valve so that the various elements making up the filling spout can be made separately and assembled according to a mounting in which they do not are not strictly coaxial without the operation of the filling spout being affected.
  • According to an advantageous version of the invention, the valve and the magnetic actuating element are mounted in separate body members connected by a quick coupling member, and the coupling elements are dissociable. It is thus possible to quickly achieve different combinations of the control member and the closure member.
  • According to an advantageous aspect of this version of the invention, one of the elements of the coupling member is a C-stirrup and the other element is a pin having a head engaged between the branches of the stirrup. After opening the quick coupling member, it is thus possible to dissociate the valve and the magnetic actuating element by a simple lateral shift thereof with respect to one another.
  • According to another advantageous aspect of the invention, the filling spout comprises a secondary shutter disposed downstream of the valve and rigidly connected thereto, and the body of the filling spout has a restriction opposite the secondary shutter, secondary shutter and the restriction having appropriate dimensions and positioning so that when the shutter closes the secondary shutter has with the restriction opposite a fair play just enough to retain by capillarity a liquid contained in the body between the valve and the secondary shutter. Without risk of interfering with the closure action of the valve, thus maintains in the filling spout a sufficient amount of product to avoid a fault formation of the product jet when opening the valve.
  • Other features and advantages of the invention will become apparent upon reading the following description of a particular embodiment of the invention and various variants thereof, with reference to the attached figures among which
    • the figure 1 is an axial sectional view of a filling spout according to the invention in a closed position of the valve,
    • the figure 2 is a view similar to that of the figure 1 in an open position of the flap,
    • the figure 3 is a partial sectional view similar to that of the figure 1 illustrating a variant of the outlet member of the filling spout,
    • the figure 4 is a partial sectional view similar to that of the figure 1 illustrating another variant of the outlet member of the filling spout,
    • the figure 5 is a front view of an embodiment variant of the valve,
    • the figure 6 is an axial sectional view of an alternative embodiment of the magnetic actuating element.
  • With reference to Figures 1 and 2 , the filling spout according to the invention comprises a tubular body 1 comprising three body members 1.1, 1.2 and 1.3 interconnected by quick coupling members 2 and respectively containing the elements providing the functions of control, shutter and outlet nozzle or secondary filling of the filling nozzle according to the invention.
  • The control function is provided by a magnetic actuating element 3 mounted to slide in the body member 1.1. In the embodiment of FIG. 1, the magnetic actuating element 3 comprises a solid magnetic core 4 provided at its periphery with guide vanes 5 which provide precise guidance of the core 4 inside the element. body 1.1 while allowing the flow of a product between the core 4 and the inner face of the body member 1.1. The body member 1.1 is made of non-magnetic material, and is surrounded by a coil 6 connected by a feed wire 9 to unrepresented feed means to form an electromagnetic actuator.
  • In the illustrated embodiment, the coil 6 is further surrounded by rings of magnetic material 7 surrounding a ring 8 forming a permanent magnet, for example a ferrite ring whose permanent magnetization field extends in an axial direction of the coil 6. At its ends the coil 6 is further covered by plates of magnetic material 10 whose periphery is in contact with the rings 7. The ferrite ring 8 is preferably sized to exert on the actuating element magnetic force 3 a force almost equal to the weight of this element and associated equipment, so that only a very small current in the coil is required to cause a displacement of the magnetic actuating element 3.
  • The body member 1.2 contains a valve 11 associated with a guide rod 12 having guide vanes 13 mounted to slide in a cylindrical bore 14 of the body member 1.2. At its upper part, the bore 14 comprises a chamfer 15 forming a seat for the valve 11 (see figure 2 ). The valve 11 comprises a hub 16 on which is mounted an O-ring 17. In the embodiment of Figures 1 and 2 , the hub 16 has a length greater than the diameter of the O-ring 17 so that the O-ring 17 is mounted on the hub 16 with an axial clearance allowing the seal 17 to slide on the hub, which makes it possible to perform an effective cleaning of the flap.
  • The link between the magnetic actuating element 3 and the valve 11 is provided by a coupling member 18. In the illustrated embodiment, the coupling member comprises a C-shaped stirrup 19 connected to the magnetic actuating member 3 by a connecting rod 20. The branches of the stirrup 19 frame a pin 21 comprising a rod 22 fixed to the valve 11 and a head 23 engaged in the stirrup 19. The rod 22 and the head 23 are mounted in the caliper with a radial clearance so that the precise sliding of the magnetic actuating member 3 in the body member 1.1 and the precise sliding of the valve 11 in the body member 1.2 are not affected even if the body elements 1.1 and 1.2 are not rigorously coaxial mounted.
  • The body member 1.3 contains a secondary shutter 24 which is fixed, for example by screwing, to the lower end of the guide rod 12 of the valve. In this embodiment, the secondary shutter 24 has an elongate conical lower portion 25 extending facing a conical restriction 26 of the body member 1.3.
  • For mounting the spout, the three body members 1.1, 1.2 and 1.3 being dissociated, the secondary shutter 24 is mounted at the lower end of the guide rod 12 of the valve, the latter not being equipped of the O-ring 17. The hub 16 of the valve is then engaged in the body member 1.2 until the hub 16 extends projecting and the seal 17 is put in place. The body member 1.3 is attached to the body member 1.2. The magnetic actuating member 3 is engaged in the body member 1.1 and then the assembly comprising the valve 11 is first shown off-set opposite the body member 1.1 to bring the head 23 level. the opening of the stirrup 19 and the body element 1.2 is brought coaxially to the body member 1.1 to engage the head 23 between the branches of the stirrup 19. The body elements 1.1 and 1.2 are then assembled by means of the quick coupling member 2.
  • In the closed position of the filling spout as illustrated by figure 1 the O-ring 17 bears on the seat 15 and the secondary shutter 25 extends near the restriction 26 in the body member 1.3. It should be noted in this regard that the dimensions and the relative positioning of the conical portion and the restriction 26 are provided so that in the closed position of the valve as illustrated, the conical portion 25 of the secondary shutter is spaced from the restriction 26 with a game just enough to retain by capillarity the product contained in the body elements 1.2 and 1.3. Furthermore, the magnetic actuating element 3 is shifted downwardly relative to the coil 6, the stirrup 19 bearing on the head 23 of the pin 21. For the opening of the valve, the coil is energized and the element magnetic actuator 3 is driven upwards as illustrated by the figure 2 . In this position, the valve 11 is open and the secondary shutter 24 is in a position allowing flow of the product.
  • In the embodiment illustrated by the Figures 1 and 2 , the elongated portion 25 of the secondary shutter 24 realizes with the restriction 26 of the element body 1.3 a passage which ensures a maintenance of the flow of the product in a laminar regime. Such a secondary shutter is useful for packaging product having a tendency to foam during a turbulent flow such as milk.
  • The figure 3 illustrates an alternative embodiment in which the secondary shutter has been removed and the body member 1.3 contains only anti-foam grids 27. This embodiment can be used in particular for the conditioning of water. In this case it is not necessary that the seal 17 of the valve 11 is mounted axially movable, and is then advantageously provided a hub 16 having a groove in which the O-ring 17 is embedded.
  • The figure 4 illustrates another variant embodiment in which the secondary shutter 28 has a small height, which makes it possible to reduce the bulk of the assembly obtained when it is not necessary to ensure a laminar flow of the product at the outlet of the beak.
  • The figure 5 illustrates an alternative embodiment of the valve in which the hub 16 is provided with a skirt 29 in which are made notches 30, which allows a more gradual evolution of the flow when opening or closing the valve .
  • The figure 6 illustrates a magnetic actuator comprising a tubular core 31. This type of actuator is preferable for thick products such as oil or products containing pulp.
  • Of course, the invention is not limited to the embodiments described and variants can be made without departing from the scope of the invention as defined by the claims.
  • In particular, although the device according to the invention has been illustrated with a coupling member comprising a C-bracket associated with a pin, which allows not only rapid assembly but also effective cleaning without the need to disassembly can be used other coupling members having a radial clearance, for example a bayonet coupling member.
