Definitions
- the present invention relates to a spraying member and a rotary coating product projection device comprising such a spraying member, and a coating product spraying installation comprising such a device.
- Conventional spraying by means of rotary devices is used to apply to objects to be coated, such as motor vehicle bodies, a primer, a base coat and / or a varnish with a coating product flow of between 100 and 500 cm 3 / min.
- objects to be coated such as motor vehicle bodies, a primer, a base coat and / or a varnish with a coating product flow of between 100 and 500 cm 3 / min.
- Paint projection devices to be mounted on these robots must therefore be capable of spraying coating products with high flow rates.
- Rotating projectors equipped with large diameter spraying devices are known from the prior art, which make it possible to spray the coating product into finer droplets and which are therefore capable of spraying the coating products with higher flow rates.
- the control of the jet of sprayed product becomes difficult, which can degrade the quality of the coating and the deposition efficiency.
- F-1 335 550 proposes, in connection with Figure 15, to increase the flow of coating product by employing a rotary device equipped with a spray member comprising a plurality of spray edges.
- Such a spraying member makes it possible to increase the useful length of spraying while maintaining a relatively compact construction radially, so easy to rotate.
- Such an organ makes it possible to spray high flows of coating product.
- the product distribution surfaces define edges of substantially identical diameter and have, in a plane of symmetry such as that of Figure 15, parallel directions, or convergent. The jets of product sprayed by these different edges are thus confluent, so that the droplets that compose them present a significant risk of recombination.
- the spray member described by FR-A-1335550 may therefore form droplets of heterogeneous dimensions, which degrades the quality of the coating.
- SU-A-733,565 discloses a spraying member for a liquid product spraying device.
- This spraying member comprises three spray edges whose diameters are identical. It therefore has a low axial compactness and a relatively high risk of recombination of the sprayed droplets.
- the invention more particularly intends to remedy by proposing a spraying member comprising at least two divergent surfaces for spraying the product.
- the subject of the invention is a spraying member for a coating product spraying device, said spraying member comprising a primary surface for distributing the product and at least two secondary surfaces, inside and outside of the distribution of the product. product extending downstream from the primary surface, the primary and secondary surfaces being coaxial, the downstream portions of the secondary surfaces respectively defining at least one inner spray edge and at least one outer spray edge, the downstream portions of the secondary surfaces having one with respect to the other of the generally divergent directions downstream, characterized in that the inner edge has a diameter substantially smaller than the diameter of the outer edge.
- the coating product is first distributed on the primary surface of the atomizer member, then it is distributed on divergent secondary surfaces downstream of which it is sprayed by the edges of different diameters, thus forming divergent jets, which avoids the recombination of the droplets.
- the droplets of sprayed product can therefore have homogeneous dimensions and thus achieve a quality coating on the object to be coated.
- the spraying member has an axial compactness which facilitates its handling.
- such a spraying member may incorporate one or more of the following features: the outer edge is axially recessed upstream with respect to the inner edge;
- the member further comprises distribution channels of the coating product each extending between an inlet located on an upstream portion of the inner secondary surface and an outlet facing an upstream portion of the outer secondary surface; the outlets being arranged on a ring coaxial with the edges;
- the member furthermore comprises orifices each extending between an inlet situated on the external surface of the spraying member and an outlet located on an upstream portion of the outer secondary surface, the inlets and outlets being arranged on a ring coaxial with the edges;
- the channels and holes consist of cylindrical holes whose outputs are distributed alternately at the upstream portion of the outer secondary surface; the channels and / or the orifices have different diameters;
- the channels and the orifices are in different numbers
- the secondary surfaces are frustoconical; - The secondary surfaces form between them and in a plane of symmetry of the spray member an angle between 16 ° and 24 °, preferably 20 °;
- the outer secondary surface has a length greater than 5 mm, preferably 10 mm; - the secondary surfaces are left;
- the member is in one piece, the secondary and primary surfaces being defined by the same piece;
- the body is composed of a body defining the primary surface and one of the secondary surfaces and a part secured to the body and defining the other secondary surface.
- the invention relates to a rotary device for projecting a coating product comprising a spraying member, means for driving this member in rotation and means for supplying this member with a coating product, this spraying member. being as previously stated.
- the invention relates to a coating product spraying installation comprising at least one rotary coating product projection device as previously discussed.
- FIG. 1 is a longitudinal sectional view of a coating product projector according to the invention used in an installation according to the invention and incorporating a spray member according to the invention;
- FIG. 2 is an axial section on a larger scale of the spray member of Figure 1;
- FIG. 3 is a partial section showing detail III in FIG. 2;
- FIG. 4 is a partial section of the spray member of Figure 2 in a plane angularly offset from the sectional plane of Figure 2;
- FIG. 5 is an axial section of a spray member according to a second embodiment of the invention.
- the projector P shown in Figure 1 is supplied with coating material from one or more sources not shown and moved, for example with a substantially vertical movement represented by the double arrow Fi, facing O objects to be coated at within an installation I coating these objects.
- the projector P comprises an air turbine whose rotor 1 is visible in Figure 1, the rotor 1 being rotated about an axis Xi-X'i.
- An annular support 4 of magnetic material for example stainless steel magnetic, is mounted on the front face 42 of the body 2, the support 4 being provided with an annular groove centered on the axis Xi-X'i and in which is disposed an annular magnet 41.
- An injector 5 coating product is housed in the center of the body 2, co-axially to the axis Xi-XV
- a spraying member 10 is mounted on the headlight P and its upstream portion forms a male frustoconical surface 12 intended to cooperate with a female frustoconical surface 11 of the rotor 1 to fasten the spraying member 10 in rotation with the rotor 1.
- effective support surfaces 12 and 11 against each other and a rotating immobilization in the manner of a Morse cone a ring 13 of ferromagnetic material is mounted on the spraying member 10, so that a attraction force F 2 due to the magnet 41 is exerted on the ring 13.
- the surfaces 11 and 12 are thus firmly pressed against each other, while an air gap E is formed between the ring 13 and support 4.
- the application of technical teaching FR-A-2 887 472 is applied here.
- the spraying member 10 has the shape of a bowl with two spray edges. Its median part forms a primary surface 20 for distributing the coating product coming from the injector 5 via a distributor 7 extending facing the upstream portion 25 of the primary surface 20.
- the terms upstream and downstream refer to the flow direction of the product from the injector 5 to the object O to be coated.
- each of the secondary surfaces 21 and 22 respectively define an inner edge 23 and an outer edge 24, on which the coating product is sprayed when the member 10 is rotated.
- the edges 23 and 24 are formed by the respective downstream ends of the secondary surfaces 21 and 22.
- the primary 20 and secondary surfaces 21 and 22 of the member 10 all have a symmetry of revolution about the axis Xio-X ' 1 0 which coincides with the axis Xi-X'i, when the member 10 is mounted on the rotor 1. These surfaces are therefore co-axial and the edges 23 and 24 in the form of a circle whose centers belong to the axis X 10 -X 1 I0 . In practice, the edges 23 and 24 may have small reliefs or "notches" to better spray the coating product.
- the primary and secondary surfaces 21 and 22 each have the shape of a truncated cone with a circular base and axis Xio-X'i. In the radial plane of FIG.
- the profile of the primary surface 20 forms a angle A 2 o of about 32 ° with the axis X 1o -X'io-
- the profile of the inner secondary surface 21 forms an angle A 2 i of about 27 ° with the X-axis X-X '10
- the profile of the outer secondary surface 22 forms an angle A 22 of approximately 45 ° with the axis Xio-X'io-
- the secondary surfaces 21 and 22, and more particularly their respective downstream portions 21b and 22b are inclined relative to each other by an angle A 22 -A 2I of 20 ° and they have divergent directions downstream, that is to say towards their edges 23 and 24.
- satisfactory results can be obtained when the secondary surfaces 21 and 22 form, between them and in a plane of symmetry of the member 10, an angle of between 16 ° and 24 °.
- the secondary surfaces 21 and 22 define circular ridges 23 and 24 having substantially different diameters D 23 and D 24 .
- the diameter D 23 may be 54 mm, while the diameter D 24 may be about 64 mm.
- the diameter D 23 of the inner edge 23 is substantially smaller than the diameter D 24 of the outer edge 24.
- the divergence of the surfaces 21 and 22 makes it possible to avoid as much as possible that the jets of product sprayed respectively by the inner and outer edges 23 and 24.
- the term "recombinant" refers here to the mixing of the jets with each other, which poses both a problem of a Vogellic disturbances and a problem of confluence of the droplets.
- the construction of the member 10 according to the invention thus makes it possible to avoid or limit the recombination of the jets, which would result in particular in increasing the size of the product droplets.
- the difference between the diameters D 23 and D 24 makes it possible to ensure good separation of the jets of sprayed product without axially lengthening the member 10 excessively.
- this axial compactness of the member 10 allows for example a multi-axis robot to easily manipulate a rotating projector which is equipped around and in the objects O to be coated.
- the edges 23 and 24 are not in the same plane, but offset axially with respect to each other, the outer edge 24 being set back by a non-zero distance di upstream with respect to the Inner edge 23.
- the distance di of withdrawal of the edge 24 with respect to the edge 23, visible in FIG. 3, can be 1 mm.
- the distance di is greater than 1% of the diameter D 23 of the inner edge 23. The greater the shrinkage di, the less jets of sprayed product may recombine.
- the secondary surfaces 21 and 22 are made in the same room as the primary surface 20.
- the member 10 is therefore one-piece, which makes it possible to obtain a good balance in rotation , to the extent that its machining is carried out with precision.
- the member 10 further comprises channels 40 for dispensing the coating product which each extend between an inlet 40a located on an upstream portion 21a of the inner secondary surface 21 and an outlet 40b facing an upstream portion 22a of the In fact, the inlet 40a of a channel 40 is at the joint of the downstream portion of the primary surface 20 and the upstream portion 21a of the inner secondary surface 21.
- the inputs 40a of all the channels 40 are arranged on a ring of frustoconical shape and coaxial with the secondary surface 21 and thus at its edge 23.
- the outlets 40b are arranged on a ring of frustoconical shape and coaxial with the secondary surface. 22 and therefore at its edge 24.
- the channels 40 consist of cylindrical holes made in a flange 26 of the member 10 forming the inner secondary surface 21.
- the channels 40 have for example a diameter of 1 mm and extend in an oblique direction forming an angle A 40 with Xio-X'io axis in a radial plane, that is to say in a plane of symmetry of the member 10. In the plane of Figure 3, the angle A 40 is about 45 °.
- the centers of the inputs 40a are situated at a distance d 4 o from the ridge 23 of, for example, 10 mm.
- the channels 40 have the function of distributing the coating product from the primary surface 20 to the outer secondary surface 22. To achieve uniform distribution, the channels 40 are regularly distributed around the Xio-X'i axis. coating material which does not flow into the channels 40 passes between these channels and reaches the inner secondary surface 21. The partition of the coating product between the secondary surfaces 21 and 22 therefore occurs at the joint between the primary surface 20 and the secondary surface 21, that is to say at the upstream portion 21a of the latter. The position and the orientation of the channels 40 are determined by the passage of the tool of piercing between the wings 26 and 27. The channels 40 are drilled so as to tangential as much as possible the outer secondary surface 22, which facilitates the cleaning of this surface and reduces its wear by the coating product.
- the member 10 also comprises orifices 50 which each extend between an inlet 50a located on the outer surface 101 of the member 10 and an outlet 50b located on an upstream portion 22A of the secondary surface 22.
- the orifices 50 are made by a cylindrical drilling operation performed in a flange 27 which defines the secondary surface 22.
- Each orifice 50 is here rectilinear and extends along an axis contained in a radial plane. It has a diameter equivalent to the diameter of the channels 40, for example 1 mm, and their inlet 50a or their outlet 50b are arranged on a ring coaxial with the edges 23 and 24.
- the orifices 50 are oblique and form an angle A 50 of about 25 ° with the axis Xio-X'10.
- channels 40 and / or orifices 50 having different diameters can be provided.
- the orifices 50 induce a flow of air on the outer side of the flange 26 forming the inner secondary surface 21, when the member 10 is rotating. Such an air flow makes it possible to fill the depression created between the ridges 24 and 23 and thus to prevent the return of droplets sprayed by the inner edge 23 into the volume situated between the wings 26 and 27. Moreover, this flow of air allows to create an induced air skirt flanking the jet sprayed by the inner edge 23, which prevents the recombination of the latter with the jet sprayed by the edge 24.
- the orifices 50 are distributed regularly around the axis Xio-X'i-Ns therefore open at the upstream portion of the outer secondary surface 22 alternately with the channels 40. In other words, the orifices 50 and the channels 40 are the same number and they are arranged alternately. However, it is possible to provide channels 40 and orifices 50 in different numbers and / or with a less regular distribution.
- the member 10 rotates about its Xio-X'i axis at a very high speed, typically between 30,000 and 70,000 rpm.
- the coating product such as a liquid paint
- the coating product is supplied by the injector 5 and it bursts against the upstream face of the distributor 7, before distributing and spreading on the primary surface 20. Downstream of the primary surface 20, the paint is distributed and spread over the secondary surface 21 until reaching the spraying edge 23 where it splits into fine droplets.
- the length L must be greater than 5 mm and preferably 10 mm.
- the partitioning of the paint between the inner 23 and outer 24 edges depends on the product flow and on the speed of rotation of the member 10. These parameters can be chosen to perform a share of about 50% for each of the edges.
- the paint can also be divided by 30% for the inner edge 23 and 70% for the outer edge 24, depending on the operating parameters adopted as a function of the desired application.
- a notched annular zone 60 may be formed on the primary surface 20 so as to set in motion all the layers of the paint film which is spread there at the same tangential speed as the channels 40. This makes it possible to promote the passage of the paint in the channels 40 and ensure that the flow remains constant on each edge 23 and 24 for a given rotation speed of the member 10.
- the notches of the zone 60 may be 2.5 mm long, 0.15 mm deep and spaced with a pitch of 0.3 mm.
- FIG. 5 illustrates a second embodiment of a spraying member according to the invention. Similar elements bear the same references as in the previous figures, increased by 100.
- the member 110 illustrated in Figure 5 differs from the body 10 by its structure and by the shape of its primary and secondary surfaces.
- the internal 121 and outer secondary surfaces 122 are here left surfaces resembling paraboloids of revolution about an axis X-no-X'no-
- the primary surface 120 has a shape similar to a paraboloid of revolution.
- left surface is meant a non-straight surface, that is to say a curved or concave profile surface with respect to the bowl 131.
- the downstream portions 121b and 122b of the secondary surfaces 121 and 122 respectively form, with respect to the central axis Xno-X'no, mean angles A 12 1 and A1 22 which define directions globally divergent downstream, that is to say toward the object O to be coated.
- the average angle of a downstream portion whose profile is not rectilinear, can be evaluated as the average of the angles formed by the tangents at each point of this profile with the central axis. In practice, it suffices to average the angles formed by a few tangents, for example four, regularly distributed along the profile of the downstream portion.
- the directions defined by the angles A 121 and A122 of the downstream portions 121b and 122b of the secondary surfaces 121 and 122 are divergent and they form between them an angle of about 10 °. As in the first embodiment, this makes it possible to avoid the recombination of the jets sprayed by the inner 123 and outer edges 124.
- the member 110 here consists of a main bowl 131 in which are drilled the channels 140 prior to the joining, for example by hooping, a ring 132 for forming the outer secondary surface 122. Orifices similar to ports 50 may be made by drilling into the member 110 to perform similar functions.
- the invention has been shown in Figures 1 and 2 with a spraying member attached to the rotor by magnetic effect.
- the spraying member may be fixed by any other means and it may in particular be screwed by means of a thread 14, adapted to cooperate with a complementary thread formed in the rotor 1, as shown in FIG. 5 for the body 110.
