    [0001] The present invention relates to a remote surface preparation device for a rigid part which extends mainly in a longitudinal direction X. There are known devices for treating the surface of a part before the deposit on this part. treated surface of a coating, this treatment may be for example a flame, activation by plasma, by corona effect, or the deposition of a primer. By remote treatment of a room, denotes the treatment in a gaseous environment. Thus, the treatment of the part by passing through a liquid bath, such as an electrolytic bath, or a paint bath, is excluded. The workpiece to be treated is a workpiece which extends substantially in a longitudinal direction, and which is rigid enough that its deformation under its own weight over a length of one meter is negligible. We therefore exclude the case of flexible films in coils. With such devices, it is possible to treat an area of the room, for example one of the faces of the room over its entire length. For this, the workpiece is positioned on a support, and the device is moved along the workpiece. To treat another area of the part, for example another face that is not accessible because it is hidden by the support (for example it rests on the support), it is necessary to position the part differently from the device, in order to present this other face vis-à-vis the device so that it is treated. This positioning operation must be repeated for all the faces to be treated, and the workpiece can not be processed in a single pass by the processing device. These operations lengthen and complicate the complete treatment of the part, and are therefore undesirable. The present invention aims to overcome these disadvantages. The object of the invention is to provide a device that makes it possible to more effectively treat all the zones (or faces) of a part that extends in a longitudinal direction. This object is achieved by virtue of the fact that this device for the preparation of a remote surface of a rigid part which extends mainly in a longitudinal direction comprises a processing means which is capable of treating all the zones of a longitudinal portion of this piece when this longitudinal portion passes into a treatment space, and a drive mechanism which is able to create a relative movement of the processing means relative to this piece in this longitudinal direction so that all the longitudinal portions of this piece are able to pass into the processing space. Thanks to these provisions, all the zones of a portion of the part that one wishes to treat are able to be treated by the device, including, for example, only two non-contiguous faces. In addition, all parts of the room are able to be treated as well. Thus the treatment of the part is performed more efficiently and quickly, in one pass, and therefore at a lower cost. According to one embodiment, the processing means is fixed in the longitudinal direction X, and the drive mechanism is able to move the workpiece in the longitudinal direction X. Advantageously, the processing means has a central volume which is the treatment space, this processing means being adapted to simultaneously treat all the areas of a longitudinal portion of the workpiece when this portion passes through this central volume.
    [0002] Thus, thanks to this simultaneous treatment, the processing time of the part is reduced. According to an exemplary embodiment, the surface preparation is a flame, and the treatment means is a burner. Finally, according to another exemplary embodiment, the surface preparation is the deposition of a tie layer, and the treatment means is a sprayer of the material forming this layer. The invention also relates to a method for preparing a surface remote from a rigid part which extends mainly in a longitudinal direction X. According to the invention, this method comprises the following steps: (a) a first longitudinal portion of the workpiece in a processing space in which all the portions of the portion are able to be processed by a processing means, (b) at least two of the portions of the portion are treated, (c) relative movement of the workpiece relative to the workpiece in the longitudinal direction X by a driving mechanism so that another longitudinal portion of the workpiece passes into the work space, and treating at least two of the areas of the other portion. For example, step (c) is iterated until all longitudinal portions of the workpiece are processed. For example, in step (b) and step (c), all areas of each treated longitudinal portion are processed by the processing means. The invention will be better understood and its advantages will appear better on reading the detailed description which follows, of an embodiment shown by way of non-limiting example. The description refers to the accompanying drawings in which: - Figure 1 is a schematic view of a device according to the invention; - Figure 2 is a schematic view of another embodiment of a device according to the FIG. 3 illustrates examples of geometries of parts that can be processed by the device according to the invention. A rigid piece 90 is to be treated which is to be remotely treated on the surface using a processing means 10. The invention relates to a remote treatment of the surface of a workpiece as defined above. This treatment is a preparation of the surface for further treatment.
    [0003] In general, the surface treatment according to the invention acts on the surface of the part, this action consisting either of a superficial modification of the part (that is to say a modification of the region of the part which is closest to its surface), or in a deposit of material on the surface of the piece.
    [0004] The action on the piece can be of any kind. The treatment device comprises a treatment means 10 which directly processes the part 90. For example, the surface treatment is a flame, and the treatment means 10 is then a burner whose flame sweeps the surface of the part 90. 302 The surface of the workpiece 90 and the region of the workpiece 90 immediately below this surface is thus impaired by exposure to a flame. For example, this surface treatment is the deposition of a tie layer, and the treatment means 10 is then a spray on the surface of the piece 90 of the material forming this layer. The part 90 extends mainly in a longitudinal direction X defined as the direction of greater dimension of the part 90. It is considered that the part 90 consists of adjacent portions 95 aligned in the longitudinal direction X. An arbitrary portion 95 is thus virtually bounded by two planes. Thus, the longitudinal direction X intersects each of these planes. The piece 90 passes through a treatment space, which is a region of the space located near the processing means 10, moving in the longitudinal direction X. In practice, a portion 95 of the piece 90 enters the processing space when the workpiece 90 moves in the longitudinal direction X, then this portion is processed during its presence in this processing space. The portion of the workpiece adjacent to this first portion 95 then enters the processing space to be processed, and so on until the entire workpiece 90 has passed into the processing space. This movement of the workpiece 90 along the longitudinal axis X may be continuous, for example at a constant speed, or incremental with interruption of displacement during the treatment of each portion 95 to be treated. In other words, a first portion 95 of the workpiece 90 is treated while the workpiece 90 is stationary, then the processing is interrupted, and the workpiece 90 is then moved relative to the processing means 10 so as to position the workpiece. Another portion of the workpiece 90 adjacent to the first portion 95 is treated with the processing space, and this other portion is processed, the workpiece 90 being stationary, and the process is iterated. This movement of the part 90 is effected by means of a drive mechanism 20 which forms part of the processing device according to the invention. This drive mechanism 20 is able to create a relative movement of the processing means 10 with respect to the workpiece 90 in the longitudinal direction X. The drive mechanism 20 comprises a support 29 of the workpiece, and a means of This drive means 22 is, for example, a motor 22 of the part 30 or the support 29. For example, the processing means 10 is fixed in the longitudinal direction X, and the drive mechanism 20 is able to move the workpiece 90 in the longitudinal direction X. According to the invention, the processing means 10 are adapted to treating all the zones 952 of a longitudinal portion 95 of the part 90 when this portion 95 passes into the treatment space, regardless of the portion 95 of the part 90. Thus, with the device of the invention it is not necessary to change the position of the workpiece 90 with respect to the processing means (in a direction other than the longitudinal direction X) to process all the surfaces 952 of a longitudinal portion 95 which is located in the treatment space. The treatment device according to the invention is able to treat all the longitudinal portions 95 of the part. As indicated above, it is therefore possible to effectively treat all longitudinal portions 95 of the part. According to the invention, only part of the portions 95 of the workpiece 90 can be processed by interrupting the treatment by the processing means 10 when one or more portions 95 of the workpiece pass into the processing space. Furthermore, with the device according to the invention, it is possible to process only non-contiguous (non-adjacent) areas (or faces) of the part 90. FIG. 1 illustrates an embodiment of the invention where the processing means 10 has a central volume 15 which is the processing space. For example, this processing means 10 has the form of a frame, which has on its inner face (in the central volume 15) heads 11 which are directed radially towards the center of this central volume 15 and which are distributed over any the inner face of the frame. The treatment emitted by each head 11 thus reaches the portion 95 when this portion 95 passes into this central volume 15. In this case where the processing means 10 has the form of a frame 35 closed radially (with respect to a longitudinal axis which passes through the space 302 7 8 2 5 6 bordered by this frame), the central volume 15 is the internal volume which is bordered radially by this frame, as illustrated in FIG. 1. Alternatively, if the processing means 10 is a shaped arch of U, that is to say an unclosed frame, the central volume 15 is the interior volume which is bordered radially in part by this frame and which opens radially on the outside by the open side of the frame. Such a processing means 10 makes it possible to simultaneously treat all the zones 952 of a portion 95 (see below). The driving mechanism 20 comprises a support 29 which carries the workpiece 90. The support 29 always occupies the same space and the workpiece 90 moves on this support 29 to pass into the treatment space, for example by translation (the translation of the piece 90 can be rectilinear or non-rectilinear (following a curve), the translation being by definition the movement of an object whose all points move at the same speed). For example, as shown in Figure 1, the support 29 is a set of cylinders located on either side of the processing means. Each cylinder pivots on itself, driven by a motor 22, which translates the part 90 in the longitudinal direction X. Alternatively, the support 29 comprises two conveyor belts, each of these mats being situated on a distinct side of the treatment space in the longitudinal direction X. Alternatively, the support 29 holds the piece 90 only by one or two of its longitudinal ends. For example, the support 29 consists of a rod on which the piece 90 is fixed at one of its ends along the longitudinal axis X (for example this rod passes through the piece 90), or two rods on each of which a end of the piece 90 is fixed. In any case, the support 29 is not located in the treatment space, so that the treatment means 10 is able to treat all the zones 952 of a longitudinal portion 95 of the part 90 when the longitudinal portion 95 passes into the treatment space, regardless of this longitudinal portion. In the example shown in Figure 1, the frame has a square shape, and the piece 90 is a square section beam. Each portion 95 is therefore substantially a cube, and each zone 952 is one of the lateral faces of this cube parallel to the longitudinal axis X. In the embodiment of FIG. 1, all the heads 11 located on the frame 10 are triggered. and operate simultaneously. This simultaneous treatment of all the faces to be treated makes it possible to shorten the total processing time of a part 90, and thus to process more parts in a given time. This configuration is valid for any portion 95 of the part 90. Thus, advantageously, the processing means 10 according to the invention 10 is able to simultaneously process all the zones 952 of a portion 95 of the part 90. Alternatively, the heads 11 process the portion 95 in sequence, operating one after the other. Alternatively, the processing means 10 may be in the form of a frame other than square, for example circular, or have the shape of a gantry, or any other form of the moment that all the areas 952 of a longitudinal portion 95 of the workpiece 90 can be processed by the processing means 10. In another embodiment, shown in FIG. 2, the processing means 10 moves around the portion 95 of the workpiece 90 while piece 90 is in the processing space. The processing means 10 is a projector 12 provided with a head 11, this projector 12 being able to pivot (by a mechanism not shown) around the longitudinal axis X over the entire circumference of the circle that this projector 12 describes. . The treatment space 15 is then the region surrounded by this circle, shown in dashed lines in FIG. 2. In this case, the translation speed of the workpiece 90 along the longitudinal axis X and the speed of rotation of the projector 12 around of this axis are chosen such that all the zones 952 of a portion 95 of the part 90 are treated while this portion 95 passes into the processing space. For example, translation of the workpiece 90 is stopped at regular intervals to allow time for all zones 952 of a portion 95 to be processed, before the workpiece 90 is translated to place the adjacent portion 95 in space treatment. In the example illustrated in FIG. 2, the part 90 is identical to the part 90 shown in FIG. 1, namely a square and constant cross section beam (a cross section is a section in a plane perpendicular to the plane). longitudinal axis X). The device according to the invention is able to also treat all parts 90 having a section other than a square section.
    [0005] For example this section is U-shaped, and in this case a portion 95 has six zones 952 which are each a plane face of the U. For example, this section is disk-shaped, or X, or I. By for example, this section is C-shaped circular, and in this case a portion 95 has a first zone 952 which is the radially outer cylindrical surface of the portion 95 and a second zone 952 which is the radially inner cylindrical surface of the portion 95. These sectional examples are illustrated in Figure 3. The section of the workpiece 90 may be constant or variable along the longitudinal axis X.
    [0006] In the case of a piece resulting from pultrusion, the device according to the invention can advantageously be placed at the pultrusion outlet. In the case where the piece 90 is a hollow tube, the piece 90 has a closed internal space that is not accessible in a radial direction (transverse).
    [0007] In this case, the processing means 10 comprises a head which is housed in this internal space, that is to say housed inside the tube and held in this space on a rod extending along the axis. longitudinal X. Thus, the area 952 which is the radially inner surface of the tube 95 is able to be treated.
    [0008] Thus, according to the invention, it is possible to reach and to treat zones of a part 90 that are difficult to reach by means of a device according to the prior art. According to another embodiment of the invention, the part 90 is fixed, and the processing means 10 moves along the part 90 in the direction of the longitudinal axis X. In this case, it is essential that the The support 29 holds the work piece 90 only by one or two of its longitudinal ends, so that the processing means 10 is able to treat all the zones 952 of each of the portions 95, and so that the translation of the processing means 10 not obstructed by the support 29. 35
