    [0001] BACKGROUND OF THE INVENTION The invention relates to a method of depositing a strip of material which comprises at least one layer to be deposited and at least one separating layer, as well as a method for removing a strip of material. has a device for its implementation. In the field of aeronautics, the composite material parts used to make a fuselage of an aircraft include a lightning protection at their outer surfaces. This lightning protection comprises at least one layer made of a material suitable for protection against lightning such as for example, and without limitation, at least one fiberglass fabric layer and / or a thin wire mesh.
    [0002] This layer for protection against lightning is obtained by depositing a plurality of strip sections, juxtaposed, on a laying surface. According to a packaging mode, the strips comprise a separation layer, for example paper, on one of their faces and are stored in the form of a coil. They have a given width of the order of 150 mm or 300 mm. These strips are generally precut so as to delimit strip sections which have a length and cutouts at each of their ends adapted so that the different strip sections are deposited one after the other and / or next to each other. others to cover the entire outer surface of the part to be made. According to one operating mode, the different strip sections are manually deposited by operators on the dispensing surface which may be the surface of a tool or the surface of the last layer deposited. To facilitate the work, a laser projection assistance system is used to project the contours of the different juxtaposed sections onto the dispensing surface. This removal operation proves difficult to achieve on a large surface removal area, such as for example a wing panel, and / or which has a large curvature, such as a fuselage section. 3033140 2 Indeed, for the sections of great lengths, it is imperative to orient them from the beginning at the risk of seeing a game or cover with the adjacent section which will increase as the progress of the setting in place of the section. If the operator tries to correct the orientation of the section during the removal, folds may appear at the section. In the case of large areas, operators do not work ergonomically. In some cases, they are forced to walk on the removal surface and possibly on the sections already deposited. To produce composite material parts from carbon fibers pre-impregnated with resin, it is known to use draping machines to automatically deposit resin pre-impregnated carbon fiber strips, packaged in the form of carbon fiber. of coils with on one of their faces a separation layer. According to an embodiment illustrated in FIG. 1, a depositing machine comprises a depositing head 10 and a mechanism (not shown) making it possible to move the depositing head 10 with respect to a depositing surface 12 in a direction of removal. characterized by the arrow 14. The dispensing head 10 comprises a support configured to support a spool 16 from which a strip 18 to be deposited on the dispensing surface 12 is unwound, a draping roll 20 enabling the strip 18 to be pressed against the dispensing surface 12. The dispensing head 10 also comprises a separation roller 22 which allows the separation layer 24 to be removed from the belt 18 and a roller 26 for storing the separation layer 24 in the form of a coil . The separating roller 22 is positioned between the spool 16 and the draping roll 20 and allows the separation layer 24 to be removed before the web 18 is compressed between the draping roll 20 and the laying surface 12. Tape 18 includes a zone between the separating roller 22 and the lay-up roll 20 without separating layer 24. According to this embodiment, the combination of the advance movement of the dispensing head 10 and the compacting action of the band 18 by the lay-up roll 20 makes it possible to exert a traction force on the band 18, which causes the reel 16 to unwind.
    [0003] This type of dispensing head is perfectly suited for carbon fiber belts that have a certain rigidity and good tensile strength.
    [0004] 3033140 3 Because lightning protection strips do not have the same characteristics as carbon fiber strips, this type of dispensing head is not suitable for automatically depositing them on a dispensing surface for the following reasons: In the absence of the separation layer 24, the strips for protection against lightning 5 can locally deform or even tear in case of excessive traction. However, as illustrated in Figure 1, there is a zone 28 of the strip between the separating roller 22 and the draping roll 20 which is separated from the separating layer 24 and can be excessively stressed. In addition, in the absence of the separation layer 24, the strip 18 for lightning protection does not have a certain rigidity. Therefore, when a portion of the strip is completely separated from the separation layer 24, a portion 30 of said section is cantilevered in front of the draping roll 20. As far as this part 30 is not It does not have a certain rigidity, it tends to curl up on itself at the front of the draping roll 20 and is not properly pressed against the deposition surface 12, as illustrated in FIG. 2. Also, this The invention aims to remedy the disadvantages of the prior art. For this purpose, the subject of the invention is a method of depositing a section on a depositing surface with a depositing head movable with respect to the depositing surface, said depositing head supporting a coil of a strip of material. which comprises at least one layer 20 to be deposited in which said section is cut and at least one separation layer, said method comprising the steps of applying the strip of material against the surface of removal and removal of the separation layer by a separator. The method is characterized in that the material web is pressed by a plating roll against the dispensing surface prior to removal of the separating layer as the dispensing head moves in a forward motion. This method makes it possible to automatically deposit sections of strips on a dispensing surface by limiting the risk of deterioration of said sections. Advantageously, the layer to be deposited is pressed by a compaction roller against the removal surface after removal of the separation layer.
    [0005] According to another characteristic, when the section to be deposited and a subsequent section are configured so that they can be in contact with the plating roller simultaneously, the plating roller is moved away from the dispensing surface before being in contact with the plating roller 3033140 4 with the next section so as to no longer press the strip of material against the dispensing surface and the strip of material is unwound from the coil synchronously with the forward movement of the dispensing head. Preferably, the separator is disposed just in front of the compaction roll so that when the section is totally detached from the separating layer, said section comprises a portion located at the front of the compacting roll with a reduced length. . Advantageously, a pad is disposed at the front of the compaction roller so that, when the section is totally detached from the separation layer, the layer to be deposited does not flow in front of the compaction roller.
    [0006] The subject of the invention is also a depositing head for the implementation of the method which comprises: a coil of a strip of material which comprises at least one layer to be deposited in which is cut a section to be deposited on a surface at least one separating layer, a separator configured to separate the separating layer and the layer to be deposited, the depositing head being characterized in that it comprises a plating roller positioned between the coil and the separator in the direction of travel of the material web and configured to press said web of material against the dispensing surface 20 when in operation the dispensing head moves in a forward motion. Advantageously, the dispensing head comprises a compaction roller positioned after the separator in the direction of travel of the material web and configured to press the layer to be deposited against the dispensing surface when in operation the dispensing head moves according to a move in advance.
    [0007] Preferably, the plating roll is movable between an exit position in which the plating roll is brought into operation close to the dispensing surface so as to press the material web against said dispensing surface and a retracted position in which the roller plating is removed in operation from the dispensing surface. According to another characteristic, the dispensing head comprises a synchronization system 30 configured to synchronize the unwinding of the strip of material with the movement of advance of the dispensing head in operation.
    [0008] According to one embodiment, the synchronization system comprises at least one motor for controlling the rotational movement of the coil and a sensor configured to measure the movement of the material web. According to another feature, the separator is disposed just in front of the compaction roller so that when the section is totally detached from the separation layer, said section comprises a portion located at the front of the compaction roller with a reduced length. According to another characteristic, the depositing head comprises a pad disposed at the front of the compacting roller.
    [0009] The invention also relates to a depositing machine comprising a depositing head according to the invention. According to one embodiment, the dispensing machine comprises a tool with a dispensing surface. According to one embodiment, the dispensing machine comprises a recovery table 15 on which possible drops may be deposited. Other features and advantages will become apparent from the following description of the invention, a description given by way of example only, with reference to the appended drawings in which: FIG. 1 is a diagram of a dispensing head which illustrates the FIG. 2 is a diagram of the dispensing head of FIG. 1 which illustrates the risks of undulation of a layer to be deposited at the front of a draping roll. FIG. 3 is a view of FIG. Figure 4 is a schematic of a dispensing head which illustrates an embodiment of the invention, FIG. 5 is a view from above of a strip of material deposited by the depositing head visible in FIG. 4; FIGS. 6A to 6F are diagrams of a depositing head which illustrate the various steps of depositing a strip section, FIGS. 7A to 7F are top views of the portion of e strip deposited by the dispensing head which illustrate the position of the rolls of the dispensing head at the different steps illustrated in Figures 6A to 6F.
    [0010] In FIG. 3, a strip of material 32 is represented. This strip of material 32 comprises at least one layer 34 to be deposited and at least one separation layer 36 applied against one of the faces of the layer 34 to be deposited. . According to one embodiment, the separation layer 36 is a separator paper and the layer 34 to be deposited is suitable for protection against lightning. By way of example and without limitation, the layer 34 to be deposited is a layer of fiberglass fabric and / or a fine wire mesh. Whatever the embodiment, the separation layer 36 is adapted to take a tensile force greater than that likely to be taken up by the layer 34 to be deposited. In addition, the tackiness between the layers 34 and 36 is less than that provided between the layer 34 to be deposited and a deposition surface. For this purpose, the separation layer 36 preferably comprises a nonstick treatment. According to one embodiment, the layer of material 32 comprises a film applied against the face of the layer 34 to be deposited opposite to the separation layer 36. According to one embodiment, the strip of material 32 has a given width of the order of 150 or 300 mm. The layers 34 and 36 have the same width as the material strip 32. According to a packaging mode, the material strip 32 is packaged in the form of a coil 38 (visible in FIG. 4). The strip of material 32 is not further described because it is known to those skilled in the art.
    [0011] Thus, the materials composing it, its width can vary from one band to another. The strip of material 32 comprises a plurality of sections 40, 40 ', 40 "to be deposited each of them being delimited in the layer 34 to be deposited by an upstream cutout 42 and a downstream cutout 44, the upstream cutout 42 being the first deposited According to a first configuration, for two adjacent sections 40 'and 40 ", the downstream cutout 44 of the section 40' is merged with the upstream cutout 42 of the section 40" In a second configuration, for two adjacent sections 40 and 40 ' the downstream cut 44 of the section 40 is disjunct from the upstream cutout 42 of the section 40 'In this case, there is a part of the band called drop 46 between the two adjacent sections 40 and 40'. cutting shapes adapted so that the different sections are deposited one after the other and / or next to each other so as to cover an entire surface, for example an outer surface of a composite material part com taking a protection against lightning.
    [0012] According to a first variant, the material strip 32 is pre-cut and the sections are already delimited before the material strip 32 is packaged in the form of a coil 38. According to another variant, the strip of material 32 is cut out. at the level of a deposition head 50, just before the layer 34 to be deposited is deposited on a deposition surface 48. Advantageously, only the layer 34 to be deposited is cut to delimit the sections 40, 40 ', 40 ", the remaining separation layer 36 continues along the entire length of the material web 32.
    [0013] According to one application, the layer 34 to be deposited is a lightning protection layer disposed at the outer surface of a composite material part forming part of a fuselage of an aircraft. According to a procedure, the various layers forming the composite material part are deposited on a tool whose geometry is adapted to that of the part to be produced 15 and then they are consolidated or polymerized so as to obtain a rigid part. Since the layer 34 to be deposited is situated at one of the faces of the part, it is deposited either directly on the tooling or on the last of the layers. For the rest of the description, a deposition surface 48 corresponds to the surface of a tool or to the surface of a layer already deposited.
    [0014] FIG. 4 shows a part of a strip removal machine which comprises a depositing head 50 supported by a displacement mechanism 52 configured to move the depositing head 50, in particular with respect to the depositing surface. 48. According to one embodiment, the displacement mechanism 52 is a robotic arm. The displacement mechanism 52 is configured to move the deposition head 50 in at least one advancing direction Da parallel to the deposition surface 48 in a normal direction Dn (visible in FIG. 6B) perpendicular to the deposition surface. 48 and / or a combination of these two directions. The displacement mechanism 52 is not further described because it may be identical to those of the prior art.
    [0015] The dispensing head 50 comprises: a frame 54 connected to the moving mechanism 52, a first coil holder 56 connected to the frame 54 and configured to receive a material strip coil 32, a second connected coil holder 58 at the frame 54 and configured to receive a recovery coil 60 of the separation layer 36, a first roller 62 connected to the frame 54 and configured to press the layer 34 to be deposited against the removal surface 48, a separator 64 connected to the frame positioned between the coil 38 and the first roller 62, configured to separate the separation layer 36 from the remainder of the material web 32 and orient it towards the recovery coil 60.
    [0016] The coils 38 and 60, the first roller 62 are positioned on the frame so that their axes of rotation are substantially parallel. The first coil support 56 is placed at the front of the dispensing head 50 and the first roller 62 is placed at the rear in the direction of advance Da. The spool 38 is configured and positioned on the first spool holder 56 so that when the material web 32 is unwound, the layer 34 to be deposited is positioned between the release layer 36 and the dispense surface 48. According to one embodiment, the separator 64 is a separation roller whose axis of rotation is substantially parallel to the first roller 62. The separator 64 is fixed relative to the frame 54 of the deposition head 50.
    [0017] Advantageously, the dispensing head 50 comprises means for adjusting the compaction force 66 exerted by the first roller 62 on the layer 34 to be deposited in the direction of the deposition surface 48. According to this configuration, the first roller 62 is called compaction roller 62. According to one embodiment, the deposition head 50 comprises a first actuator 68 connected to the frame 54, said actuator 68 comprising a rod 70 movable in translation in a direction perpendicular to the deposition surface 48 to which is The dispensing head 50 preferably comprises a cutting system 72 configured to cut at least partially the material web 32 so as to delimit sections 40, 40 ', 40 "to be deposited. , the cutting system 72 is configured to cut only the layer 34 to be deposited and delimit in this layer 34 the different sections 40, 40 ', 40 "to depositing, the separation layer 36 not being cut and remaining continuous. According to one embodiment, the cutting system 72 is an ultrasonic cutting system connected to the frame 54 and positioned under the coil 38, in front of the material strip 32.
    [0018] According to a feature of the invention, the dispensing head 50 comprises a second roller 74 connected to the frame, positioned between the coil 38 and the separator 64 in the direction of travel of the material web and configured to press the web of material. 32 against the dispensing surface 48 before the separation layer 36 is separated from the layer 34 to be deposited. This second roller 74 being located at the front of the separator 64, the layer 34 to be deposited is never stressed in tension when it is separated from the separation layer 36. Between the coil 38 and the second roller 74, the material strip 32 is subjected to a tensile stress. However, this tensile force is taken up by the separation layer 36 which is always closely linked to the layer 34 to be deposited. Preferably, the second roller 74 is movable in translation between an extended position 15 in which the second roller 74 is brought into operation close to the deposition surface 48 so as to exert a plating force on the strip of material 32 against the surface of the deposit 48 and a retracted position in which the second roller 74 is spaced apart from the deposition surface 48 and exerts no plating force. This configuration makes it possible to be able to deposit sections 40 with at least one cutting edge.
    [0019] For the rest of the description, the second roller 74 is referred to as the ply roll 74. Advantageously, the dispensing head 50 comprises a second actuator 76, connected to the frame 54, which supports the plating roller 74 to make it movable. According to one embodiment, the actuator 76 comprises a rod 78 movable in translation in a direction perpendicular to the dispensing surface 48 to which the plating roll 74 is connected.
    [0020] Preferably, the separator 64 is positioned just in front of the compacting roller 62 so as to be slightly spaced from said compacting roller 62. To give an order of magnitude, the point of contact of the compaction roller 62 with the layer 34 to be deposited and the separation zone of said layer 34 with the separation layer 36 are separated by a distance of less than 10 cm.
    [0021] This configuration makes it possible to limit the portion of the cantilevered section at the front of the compaction roller 62 when said section is totally separated from the separation layer 36.
    [0022] Advantageously, the depositing head 50 comprises a shoe 80 positioned between the separator 64 and the compacting roller 62. According to one embodiment, the pad 80 has a length such that its first end is spaced a small gap with the point of contact of the compacting roller 62 with the layer 34 to be deposited and its second end 5 is spaced from a slight clearance with the separation zone of the layers 34 and 36. For weak clearance, means a clearance of less than 1 cm . In addition, the pad 80 is positioned in height relative to the separator 64 so as to be spaced from the layer 34 to deposit a clearance of the order of 1 to 4 mm. This configuration makes it possible to avoid the appearance of undulations at the level of the layer 34 to be deposited at the front of the compacting roller 62. The various rollers 62, 64, 74 and the pad 80 have a width slightly greater than that of the material web 32. They are preferably centered with respect to said web of material 32. According to another characteristic of the invention, the deposition head 50 comprises a system 15 for synchronizing the unwinding movement of the reel 38 with the advance movement of said depositing head 50, at least when the plating roller 74 is not in contact with the material strip 32. This configuration makes it possible to prevent the layer 34 to be deposited from being subjected to an effort when the plating roll 74 is moved away from the web of material, for example at the end of the removal of a section with a pointed end. This synchronization system comprises at least one motor 82 for controlling the rotational movement of the coil 38, the rotational movement of said motorization being slaved to the advance movement of the dispensing head. Preferably, the synchronization system comprises an actuator for controlling the rotational movement of the recovery coil 60, the rotational movement of said motorization being slaved to the advance movement of the dispensing head. To accurately determine the feed movement of the dispensing head 50, the synchronization system preferably comprises a sensor 84 configured to measure the travel of the material web 32 when in contact with the dispensing surface. 48 or just before it comes into contact with the dispensing surface 48. According to one embodiment, this sensor 84 is an encoder wheel in contact with the surface of the strip of material 32 covered by the separation layer 36. The encoder wheel is connected to the frame 54 and positioned at the front of the compaction roll 62. In one configuration, the encoder wheel is positioned just in front of the plating roll 74. Preferably, the dispensing head 50 comprises a guide 86 connected to the frame 54 and positioned to be in contact with the surface of the material web 32 covered by the separation layer 36 and to guide said web of material re 32 between the coil 38 and the plating roller 74. This guide 86 improves the positioning of the material strip 32 relative to the cutting system 72 and / or the sensor 84. The dispensing machine comprises in addition to the dispensing head 50 a control / command station which controls the movements of the dispensing head 50 and the plating roll 74, the compaction force applied by the compaction roller 62. This control / command station also makes it possible to control the rotational movement of the actuator 82 as a function of the measurements of the sensor 84. Preferably, the depositing machine comprises a frame on which can be removably secured a tool with a dispensing surface whose geometry is adapted to that of the part to be produced and a recovery table on which can be deposited any falls 46. The operating principle of the dispensing machine is now e FIGS. 6A to 6F and 7A to 7F when removing a section 40 with an upstream cutout 42 and a downstream cutout 44.
    [0023] The portion of the upstream cutout 42 of the innermost portion 40 of the dispensing head 50 is positioned at the lower generatrix of the plating roll 74, as shown in FIGS. 6A and 7A. This upstream cutout 42 may have been obtained with the cutting system 72. The depositing head 50 is moved so as to have the upstream cutout 42 plumb with 25 of a docking position 88 which corresponds to the position of FIG. the upstream cutout 42 on the dispensing surface 48. Next, the dispensing head 50 is moved in the direction Dn so as to clamp the material web 32 between the plating roller 74 and the dispensing surface 48, as illustrated in FIG. Figure 6B. The position of the dispensing head 50 with respect to the depositing surface 48 is adjusted so that the plating roll 74 exerts a force of about 5 N per mm of web width 32.
    [0024] As shown in FIG. 6C, the dispensing head 50 is moved in the direction of advance Da. During this movement, the strip of material 32 being pressed against the deposition surface 48, the portion 40 of the layer 34 to be deposited adheres to the deposition surface 48. At the separator 64, the separation layer 36 is removed for to be wound up at the level of the recovery coil 60. Once initiated, the separation of the layers 34 and 36 propagates laterally (perpendicular to the length of the strip of material 32) and longitudinally (parallel to the length of the strip of material 32) from the initial point of separation, as the dispensing head 50 advances. At the rear of the separator 64, the compaction roller 62 applies a compaction force 10 to the layer 34 to be deposited. . During this phase, the plating roll 74, in contact with the separation layer 36, plates the strip of material 32 against the depositing surface 48. In this way, the strip of material 32 via the layer 34 The deposition of the material web 32 is caused by the combination of adhesion of the material web 32 to the deposition surface 48 and the advancing movement of the deposition head. 50. The layer 34 to be deposited feels no traction force, the latter being taken up by the separation layer 36. Depending on the downstream cut 44, the plating roller 74 may be in contact with the section 40 but also with a another section 40 'or a chute 46, for example when said section 40 comprises a pointed shape 90. As illustrated in FIGS. 6D and 7D, just before reaching this pointed form 90, the plating roll 74 is moved towards the retracted position g With the actuator 76, the plating roll 74 is spaced a few millimeters from the depositing surface 48 so as not to press the end 92 of the following section 40 'against the depositing surface 48.
    [0025] By following, as illustrated in FIG. 6E, the dispensing head 50 continues its advance movement so as to finish the removal of the section 40. As soon as the plating roller 74 is no longer in contact with the material strip 32, the unwinding of the spool 38 is synchronized with the advance movement of the dispensing head 50 by means of the motor 82 and the sensor 84. Preferably, the rotational movement of the recovery spool 60 is also synchronized with the advance movement of the dispensing head. This synchronization avoids any tensile force in the layer 34 to be deposited. The compacting roller 62 provides the plating of said layer 34.
    [0026] Since the separator 64 is slightly spaced from the compaction roller 62, the length of the section 40 situated at the front of the compaction roller 62 is reduced when the section 40 is totally detached from the separation layer 36. since the cantilevered section 40 is short, the risk of having it curl up on itself at the front of the compacting roller 62 is limited. Finally, the pad 80 prevents any risk of bending of said portion on itself. During this advance movement, the compaction roller 62 makes it possible to separate the section 40 from the separating layer 26. The fact of moving the plating roll 64 aside makes it possible to keep the end of the section 40 'always facing against each other. the separation layer 36. Thus, the separation of the two sections 40 and 40 'is obtained. As illustrated in FIG. 6F, as soon as all the section 40 is pressed against the deposition surface 48, the deposition head 50 is moved away from the deposition surface 48. The strip of material 32 is rewound so that the cutting Upstream 42 of the next section 40 'is positioned plumb with the lower generatrix of the plating roll 74. This plating roll 74 is repositioned in the extended position. It is then possible to proceed to the removal of the next section 40 'as previously described. If the next section is a drop 46, the latter is deposited on the recovery table in the same way as the sections to be deposited on the depositing surface, the fall 46 corresponding to a section that is not to be deposited on the surface. of deposit 48.
