Selon une variante de réalisation, le magasin se présente sous la forme d'une caisse ouverte sur le dessus, disposée longitudinalement sur le poste de conduite de la machine et il comporte des moyens d'expulsion des piquets vers le système de prélèvement, lesquels moyens sont constitués de sangles qui forment une sorte d'auge déformable, lesquelles sangles sont, d'un côté, fixées sur la partie supérieure de la paroi latérale du magasin côté poste de conduite et, de l'autre côté, elles sont guidées par des galets situés à un niveau sensiblement inférieur à celui de ladite paroi latérale, et elles s'étendent ensuite jusqu'à un dispositif enrouleur qui permet de réduire selon les besoins la capacité et le volume de l'auge et, dans le même temps, d'évacuer les piquets au fur et à mesure vers ledit système de prélèvement.According to an alternative embodiment, the store is in the form of a box open on the top, arranged longitudinally on the machine operator's station and it includes means for expelling the stakes towards the sampling system, which means consist of straps which form a kind of deformable trough, which straps are, on one side, fixed on the upper part of the side wall of the magazine on the driver's side and, on the other side, they are guided by rollers located at a level substantially lower than that of said side wall, and they then extend to a winding device which makes it possible to reduce, as necessary, the capacity and the volume of the trough and, at the same time, d '' evacuate the stakes progressively to said sampling system.
Selon une autre disposition de l'invention, le système de prélèvement des pieux dans le magasin comprend un organe de prélèvement en forme dé Vé, situé selon le cas, soit au niveau de l'arrête du dièdre qui forme le fond du magasin, soit au niveau des galets de freinage des courroies, lequel Vé est mobile verticalement, porté par une poutre guidée à chacune de ses extrémités dans des glissières verticales aménagées dans les parois avant et arrière dudit magasin, laquelle poutre est mobile verticalement sous l'effet par exemple d'un compas qui permet son déplacement parallèlement à elle-même dans ledit magasin, traversant la masse des pieux ou piquets stockée dans ce dernier, lequel compas est constitué de bras et guides dont l'épaisseur correspond à l'épaisseur de ladite poutre et à la largeur dudit Vé.According to another arrangement of the invention, the system for picking up piles in the store comprises a V-shaped picking member, located as the case may be, either at the level of the dihedral stop which forms the bottom of the store, or at the level of the braking rollers of the belts, which V is movable vertically, carried by a beam guided at each of its ends in vertical slides arranged in the front and rear walls of said magazine, which beam is movable vertically under the effect for example a compass which allows it to move parallel to itself in said store, passing through the mass of piles or stakes stored in the latter, which compass consists of arms and guides whose thickness corresponds to the thickness of said beam and to the width of said Vé.
Toujours selon l'invention, le Vé de prélèvement des pieux ou piquets dans le magasin, est articulé à son extrémité avant sur sa poutre porteuse et il comporte un doigt placé en amont de son axe d'articulation sur ladite poutre, lequel doigt coopère avec une butée disposée à l'extrémité supérieure du guide de ladite poutre, sur la parois avant du magasin, laquelle butée permet, en coopération avec ledit doigt, de faire basculer le Vé par rapport à sa poutre porteuse lorsque cette dernière arrive en fin de course haute, lequel basculement provoque l'échappement gravitaire du pieu embarqué par ledit Vé, lequel pieu s'échappe en étant guidé au moyen d'un toboggan aménagé à l'avant du magasin et se il se positionne dans un bac récepteur situé à la partie inférieure de l'enfonce-pieux, solidaire des bras support du berceau dudit enfonce-pieux, lequel bac est muni d'un dispositif du genre capteur qui permet de détecter la présence d'un pieu dans ledit bac. Selon une autre disposition de l'invention, le Vé de prélèvement des pieux dans le magasin comporte, sur sa longueur, disposé vers ses extrémités, des électro-aimants qui, notamment dans le cas de pieux métalliques de type ouvert à section en forme d'oméga, permettent de retenir le pieu situé dans le fond dudit Vé et, en cas de prélèvement et d'enlèvement intempestif d'une paire de pieux simultanément qui sont par exemple imbriqués l'un dans l'autre, de ne laisser s'échapper. que le pieu qui n'est pas en contact avec lesdits électro-aimants, ce pieu libre descend par simple gravité vers le bac récepteur de l'ènfonce-pîeux, lequel bac comporte le capteur de détection d'arrivée d'un pieu qui donne une information, laquelle information, traitée par un automate approprié, permet de contrôler la libération du second pieu resté en place dans le Vé, au moyen d'une désactivation des électro-aimants.Still according to the invention, the Vee for picking up stakes or stakes in the magazine, is articulated at its front end on its support beam and it comprises a finger placed upstream of its axis of articulation on said beam, which finger cooperates with a stopper disposed at the upper end of the guide said beam, on the front wall of the magazine, which stop makes it possible, in cooperation with said finger, to tilt the Vee relative to its carrying beam when the latter arrives at the end of the high stroke, which tilting causes the gravitational escape of the pile on board by said Vé, which stake escapes while being guided by means of a slide fitted at the front of the store and if it is positioned in a receiving tank located at the lower part of the post driver, secured to the arms support for the cradle of said pile driver, which bin is fitted with a sensor-type device which makes it possible to detect the presence of a pile in said bin. According to another arrangement of the invention, the Vee for picking up piles in the magazine comprises, along its length, disposed towards its ends, electromagnets which, in particular in the case of open type metal piles with d-shaped section 'omega, allow to retain the stake located in the bottom of said Vé and, in the event of untimely removal and removal of a pair of stakes simultaneously which are for example nested one inside the other, not to let s' escape. that the pile which is not in contact with said electromagnets, this free pile descends by simple gravity towards the receptacle for the post driver, which container comprises the sensor for detecting the arrival of a stake which gives information, which information, processed by an appropriate automaton, makes it possible to control the release of the second pile remaining in place in the Vé, by means of a deactivation of the electromagnets.
Toujours selon l'invention, le toboggan de guidage des pieux dès leur sortie du Vé de prélèvement, comporte, - à sa partie supérieure, une première portion munie de moyens de guidage et de freinage comprenant par exemple une paire de patins en matériaux du genre caoutchouc, et - une seconde portion entre ladite première portion et le bac de réception des pieux, laquelle seconde portion, en forme de goulotte, est articulée à sa partie inférieure, sur le châssis de la machine, de façon à pouvoir basculer sous l'effet d'un vérin de manœuvre par exemple, pour relever le pieu dont l'extrémité est posée dans ledit bac et ainsi le présenter au système de pinces de l'enfonce-pieux.Still according to the invention, the pile guide slide as soon as they leave the sampling Vee, comprises, - at its upper part, a first portion provided with guidance and braking means comprising for example a pair of runners made of similar materials rubber, and - a second portion between said first portion and the pile receiving tank, which second portion, in the form of a chute, is articulated at its lower part, on the chassis of the machine, so as to be able to tilt under the effect of an actuating cylinder for example, to raise the pile whose end is placed in said tank and thus present it to the clamp system of the post driver.
Toujours selon l'invention, le dispositif de réglage de l'orientation du pieu prêt à être planté, est constitué d'un organe en forme de chapeau par exemple, muni de moyens d'entraînement coopérant avec la partie supérieure du pieu et, éventuellement, avec un aménagement du pieu qui favorise son entraînement, lequel chapeau est mobile en rotation sous l'effet d'un organe moteur approprié, et il est porté au moyen d'un support qui est monté sur la tête de l'enfonce-pieux avec un degré de liberté verticale qui permet de poser le chapeau sur la tête du pieux, en douceur, lequel support est également doté d'une possibilité de mouvement autour d'un axe vertical, parallèle à l'axe de déplacement de ladite tête, de façon à pouvoir passer d'une position inactive en dehors de la ligne d'enfoncement du pieu, à une position active située entre la partie supérieure du pieu et la cloche de l'enfonce-pieux, lequel chapeau d'orientation est manœuvré soit de façon automatique grâce à une indexation aménagée sur le pieu et sous le contrôle d'un automate, soit directement par l'opérateur qui agit à partir du poste de conduite ;Still according to the invention, the device for adjusting the orientation of the pile ready to be planted, consists of a hat-shaped member for example, provided with drive means cooperating with the upper part of the pile and, optionally, with an arrangement of the pile which favors its drive, which cap is movable in rotation under the effect of an appropriate motor member, and it is worn by means of a support which is mounted on the head of the post driver with a vertical degree of freedom which allows the cap to be placed on the head of the post, gently, which support is also provided with a possibility of movement around '' a vertical axis, parallel to the axis of movement of said head, so as to be able to pass from an inactive position outside the driving line of the pile, to an active position located between the upper part of the pile and the bell of the post driver, which orientation cap is operated either automatically thanks to an indexing arranged on the pile and under the control of an automaton, or directly by the operator who acts from the driving position te;

Telle que représentée sur les figures 1 et 6 à 8, la machine de plantation comprend un châssis 1 automoteur muni de quatre roues 2, d'un poste de conduite central 3 disposé latéralement, et d'un groupe de propulsion 4 central disposé latéralement, à côté du poste de conduite.As shown in FIGS. 1 and 6 to 8, the planting machine comprises a self-propelled chassis 1 provided with four wheels 2, a central driving position 3 arranged laterally, and a central propulsion group 4 arranged laterally, next to the driving position.
A sa partie avant, la machine est équipée d'un enfonce-pieux 5 qui comprend un berceau 6 porté par des bras de relevage 7 reliés entre eux pour former une structure rigide. Ce berceau 6 est articulé sur l'extrémité avant des bras 7 autour d'un axe 9 qui constitue un axe de tangage disposé transversalement et horizontalement à l'avant de la machine. Le berceau 6 est mobile autour de l'axe 9 au moyen d'un vérin 10 interposé entre le châssis 1 et la partie supérieure du berceau 6. Le berceau 6 est également mobile verticalement par rapport au châssis 1 au moyen d'un vérin 11 interposé entre ledit châssis et les bras 7.At its front part, the machine is equipped with a post driver 5 which comprises a cradle 6 carried by lifting arms 7 connected together to form a rigid structure. This cradle 6 is articulated on the front end of the arms 7 around an axis 9 which constitutes a pitch axis arranged transversely and horizontally at the front of the machine. The cradle 6 is movable around the axis 9 by means of a jack 10 interposed between the chassis 1 and the upper part of the cradle 6. The cradle 6 is also movable vertically relative to the chassis 1 by means of a jack 11 interposed between said chassis and the arms 7.
L'enfonce-pieux 5 se présente sous la forme d'un ensemble autonome c'est-à-dire qu'il comprend son propre groupe générateur 12 installé sur le berceau 6, lequel groupe alimente les différents vérins chargés de positionner la tête 13 et les pinces 14 à l'endroit voulu pour planter un pieu 15 dont la section apparaît figures 2 à 4 par exemple. La tête 13 et le système de pinces 14, sont portés par un mât 16 qui est lui-même, de façon classique, articulé sur une structure 17 comportant des glissières horizontales disposées transversalement par rapport au sens de l'avancement de la machine.The post driver 5 is in the form of an autonomous assembly, that is to say it comprises its own generator group 12 installed on the cradle 6, which group supplies the various jacks responsible for positioning the head 13 and the clamps 14 at the desired location for planting a stake 15, the section of which appears in FIGS. 2 to 4 for example. The head 13 and the clamp system 14 are carried by a mast 16 which is itself, conventionally, articulated on a structure 17 comprising horizontal slides arranged transversely to the direction of advance of the machine.
L'axe d'articulation 18 situé entre le mât 16 et la structure 17 est un axe longitudinal qui correspond en quelque, sorte à un axe de roulis et le mouvement du mât 16 autour de cet axe 18 est provoqué par un vérin 19 qui est monté sur la structure 17, visible notamment figure 8. Sur la figure 17, détaillée ci-après comme variante, le mouvement du mât 16 autour de Taxe 18 s'effectue au moyen d'un vérin 19' installé en forme de hauban entre la structure 17 et la partie supérieure dudit mât, de façon à améliorer le contrôle de la position de ce dernier. Selon cette variante de réalisation, représentée figure 17, le berceau comprend un bâti 6' relié au bras de relevage 7 ; ce bâti 6' est mobile sur l'axe 9 sous l'effet du vérin 10 qui est porté par le châssis 1. A l'avant du bâti 6' la structure 17 qui est formée du système de glissières 47, 48, est articulée sur un axe vertical 8 qui constitue l'axe de lacet. Cet axe 8 est disposé latéralement du côté de l'enfonce-pieux et la structure 17 est mobile par rapport au bâti 6', sous l'effet d'un vérin 17' porté par ledit bâti 6'.The articulation axis 18 located between the mast 16 and the structure 17 is a longitudinal axis which corresponds in some way to a roll axis and the movement of the mast 16 around this axis 18 is caused by a jack 19 which is mounted on the structure 17, visible in particular in FIG. 8. In FIG. 17, detailed below as a variant, the movement of the mast 16 around Taxe 18 is effected by means of a jack 19 ′ installed in the form of a stay cable between the structure 17 and the upper part of said mast, so as to improve the control of the position of the latter. According to this alternative embodiment, represented in FIG. 17, the cradle comprises a frame 6 'connected to the lifting arm 7; this frame 6 ′ is movable on the axis 9 under the effect of the jack 10 which is carried by the chassis 1. At the front of the frame 6 ′ the structure 17 which is formed by the system of slides 47, 48, is articulated on a vertical axis 8 which constitutes the yaw axis. This axis 8 is disposed laterally on the side of the post driver and the structure 17 is movable relative to the frame 6 ', under the effect of a jack 17' carried by said frame 6 '.
Cet axe de lacet 8 permet de déplacer légèrement l'enfonce-pieux, longitudinalement, évitant de manœuvrer la machine proprement dite.This yaw axis 8 makes it possible to slightly move the post driver, longitudinally, avoiding to maneuver the machine itself.
Les pieux 15 sont stockés dans un magasin 20 qui est disposé longitudinalement à côté du poste de conduite 3, au-dessus de l'organe moteur 4 de la machine. Ce magasin est doté d'un système de prélèvement et ensuite d'expédition des pieux un par un vers l'enfonce-pieux et en particulier vers un bac récepteur 21 situé à l'avant de la machine, porté en bout des bras 7 et en particulier monté sur une prolonge 22 à l'extrémité avant du bras 7, laquelle prolonge se situe du côté de la tête 5 de l'enfonce-pieux.The piles 15 are stored in a magazine 20 which is arranged longitudinally next to the driving position 3, above the motor member 4 of the machine. This store is equipped with a system for picking up and then shipping the piles one by one to the pile driver and in particular to a bin receiver 21 located at the front of the machine, carried at the end of the arms 7 and in particular mounted on an extension 22 at the front end of the arm 7, which extension is located on the side of the head 5 of the post driver .
Ce bac récepteur 11 sera détaillé plus loin en liaison avec les figures qui illustrent le magasin et l'opération de prélèvement des pieux dans ce dernier.This receiving tank 11 will be detailed later in conjunction with the figures which illustrate the store and the operation of picking the piles therein.
On remarque, figure 6, que le magasin 20 est incliné vers l'avant de la machine, d'un angle de l'ordre de 10°, afin de privilégier une certaine position des pieux 15 à l'intérieur, et en particulier une position dans laquelle les pieux 15 sont en appui sur la face avant 23 dudit magasin. Le magasin est chargé avec des fagots de pieux ou piquets, lesquels fagots sont pris au sol par exemple, au moyen d'un bras de levage 25 disposé à l'arrière de la machine. Ce bras de relevage 25 forme une sorte de grue installée sur un pivot vertical 26 et elle est commandée par l'opérateur soit depuis le poste de conduite 3, soit à. partir d'un pupitre approprié non représenté, situé à proximité, c'est à dire à l'arrière de la machine,.Note, FIG. 6, that the magazine 20 is inclined towards the front of the machine, by an angle of the order of 10 °, in order to favor a certain position of the piles 15 inside, and in particular a position in which the piles 15 are supported on the front face 23 of said magazine. The magazine is loaded with bundles of piles or stakes, which bundles are taken from the ground for example, by means of a lifting arm 25 disposed at the rear of the machine. This lifting arm 25 forms a sort of crane installed on a vertical pivot 26 and it is controlled by the operator either from the driving position 3 or from. from a suitable console not shown, located nearby, that is to say at the rear of the machine.
La section des pieux ou piquets 15 est représentée figures 2, 3 et 4. La figure 2 montre différentes possibilités de pieux ou piquets dé section cylindrique dont le diamètre peut varier par exemple de 30 à 140 mm.The section of the stakes or stakes 15 is shown in Figures 2, 3 and 4. Figure 2 shows different possibilities of stakes or stakes of cylindrical section whose diameter can vary for example from 30 to 140 mm.
La figure 3 montre un pieu spécifique pour la vigne, réalisé en métal, de section ovale.Figure 3 shows a specific pile for the vine, made of metal, of oval section.
Ce pieu est également représenté partiellement figure 5, vu de côté c'est-à- dire vu du côté de sa grande face. Les flancs 27 de ce pieu 15 représenté figure 5, comportent des découpes 28 dont l'une est représentée à part et de façon agrandie. Cette découpe est une découpe classique qui permet d'encastrer un fil non représenté, et de le verrouiller sur le pieu.This pile is also partially represented in FIG. 5, seen from the side, that is to say seen from the side of its large face. The sides 27 of this pile 15 shown in FIG. 5 have cutouts 28, one of which is shown separately and in an enlarged manner. This cut is a classic cut that allows to embed a wire not shown, and to lock it on the stake.
Ces découpes 28 sont disposées sur chaque flanc 27, mais d'une façon décalée verticalement pour éviter de fragiliser le pieu.These cutouts 28 are arranged on each side 27, but in a vertically offset manner to avoid weakening the pile.
La figure 4 montre une section d'un autre pieu métallique utilisé poϋr la vigne. Ce pieu 15 a une section en forme d'oméga et comporte lui aussi des encoches, non représentées, qui permettent de fixer des fils.Figure 4 shows a section of another metal stake used for the vine. This pile 15 has a section in the shape of an omega and also has notches, not shown, which allow wires to be fixed.
Les pieux représentés figures 3 et 4 requièrent une orientation précise par rapport à la ligne de plantation. Lorsqu'ils sont positionnés au niveau de l'enfonce- pieux, sous la tête 13, ces pieux sont préalablement soumis à une opération de réglage de leur orientation. Cette opération de réglage et d'ajustement de l'orientation des pieux 15 s'effectue lorsque ces pieux sont posés dans le bac récepteur 21 et maintenu par le système de pinces 14. Le dispositif d'orientation des pieux apparaît figure 1 , et figures 6 et 7. Il est représenté de façon plus détaillée figures 9 et 10.The piles shown in Figures 3 and 4 require precise orientation relative to the planting line. When positioned at the push-in level piles, under the head 13, these piles are previously subjected to an operation for adjusting their orientation. This adjustment and adjustment operation of the orientation of the piles 15 is carried out when these piles are placed in the receiving tank 21 and maintained by the clamp system 14. The device for orienting the piles appears in FIG. 1, and FIGS. 6 and 7. It is shown in more detail in FIGS. 9 and 10.
Ce système d'orientation des pieux est monté sur la tête 13 de l'enfonce- pieux 5. Il comprend un chapeau 31 qui coopère comme représenté figure 10, avec l'extrémité supérieure du pieu 15. Ce chapeau 31 , de forme conique par exemple, est monté sur un support 32 et il est manœuvré en rotation au moyen d'un organe moteur 33 par l'intermédiaire d'une transmission quelconque 34.This pile orientation system is mounted on the head 13 of the pile driver 5. It comprises a cap 31 which cooperates as shown in FIG. 10, with the upper end of the pile 15. This cap 31, of conical shape by example, is mounted on a support 32 and it is rotated by means of a drive member 33 via any transmission 34.
Le support 32 est monté sur un bras vertical 35, articulé autour d'un axe vertical 36 sur ledit-bras. Ce bras 35 est guidé verticalement dans un fourreau 37 solidaire de la tête 13 et il est mobile verticalement, guidé dans ce fourreau 37. Le positionnement du support 32 et du chapeau 31 , soit en position inactive comme représenté figure 9, soit en position active comme représenté figure 10, s'effectue au moyen d'un vérin 38 qui est interposé entre ledit support et une patte 39 solidaire de l'extrémité inférieure du bras 35.The support 32 is mounted on a vertical arm 35, articulated around a vertical axis 36 on said arm. This arm 35 is guided vertically in a sleeve 37 secured to the head 13 and it is movable vertically, guided in this sleeve 37. The positioning of the support 32 and of the cap 31, either in the inactive position as shown in FIG. 9, or in the active position as shown in FIG. 10, is carried out by means of a jack 38 which is interposed between said support and a lug 39 secured to the lower end of the arm 35.
Le mouvement de pivotement du support 32 permet de placer le chapeau 31 sous la cloche 40 de la tête 13 c'est-à-dire très précisément à la verticale du pieu 15 et de l'endroit où ce dernier doit être planté.The pivoting movement of the support 32 makes it possible to place the cap 31 under the bell 40 of the head 13, that is to say very precisely vertical to the pile 15 and from the place where the latter must be planted.
Lorsque le chapeau 31 a été amené au-dessus du pieu 15, lequel pieu est rappelons-le maintenu par le système de pinces 14, la tête 13, guidée sur son mât vertical 16 est déplacée pour amener ledit chapeau 31 sur le poteau 15, lequel poteau rappelons-le également, repose dans le bac récepteur 21. Pour établir un contact en douceur entre le chapeau 31 et le dessus du pieu 15, on remarque que le bras 35 coulisse librement dans le fourreau 37 et qu'il est suspendu au moyen d'un organe élastique du genre ressort 42,. interposé entre la tête et l'extrémité supérieure 43 du bras 35 ; la pression exercée par le chapeau 31 sur le dessus du pieu 15 est ajustable au moyen du ressort 42.When the cap 31 has been brought above the pile 15, which pile is remembered to be maintained by the clamp system 14, the head 13, guided on its vertical mast 16 is moved to bring said cap 31 to the pole 15, which post also remember, rests in the receiving tank 21. To establish a smooth contact between the cap 31 and the top of the pile 15, we note that the arm 35 slides freely in the sheath 37 and that it is suspended from the by means of an elastic member of the spring type 42 ,. interposed between the head and the upper end 43 of the arm 35; the pressure exerted by the cap 31 on the top of the pile 15 is adjustable by means of the spring 42.
Lorsque le chapeau 31 est posé sur l'extrémité supérieure du pieu 15, le bras 35 est immobilisé alors que la tête 13 continue à descendre. Un capteur 44 est disposé sur ladite tête13 et il est manœuvré par l'extrémité supérieure 43 du bras 35, donnant une information qui correspond à la mise en position active du chapeau 31 sur le pieu 15, laquelle information permet d'engager l'opération d'orientation du pieu 15, lequel pieu étant toujours maintenu par le système de pinces 14.When the cap 31 is placed on the upper end of the pile 15, the arm 35 is immobilized while the head 13 continues to descend. A sensor 44 is disposed on said head 13 and it is operated by the upper end 43 of the arm 35, giving information which corresponds to the active positioning of the cap 31 on the pile 15, which information makes it possible to initiate the orientation operation of the pile 15, which pile is still maintained by the clamp system 14.
Le système de pinces 14 comprend des mâchoires en forme dé Vé qui permettent d'enserrer le pieu 15. Ces mâchoires sont manœuvrées par un vérin 46 qui apparaît figure 8, lequel vérin permet de maintenir le pieu d'une façon souple, selon une orientation précise grâce à une interaction entre ledit pieu du fait de sa forme ovale ou autre et les mâchoires en forme de Vé.The clamp system 14 includes V-shaped jaws which allow the pile 15 to be clamped. These jaws are operated by a jack 46 which appears in FIG. 8, which jack allows the stake to be held in a flexible manner, in an orientation precise thanks to an interaction between said stake due to its oval or other shape and the V-shaped jaws.
Cette opération d'ajustement de l'orientation du pieu 15, peut s'effectuer soit de façon automatique par des moyens appropriés comme par exemple des moyens de reconnaissance de formes ou de détection d'un aménagement particulier sur le pieu du type détrompeur, soit par l'intervention de l'opérateur qui, depuis son poste de conduite, peut corriger l'orientation du pieu en fonction de son orientation prévue sur la ligne de plantation. . .This operation of adjusting the orientation of the pile 15 can be carried out either automatically by appropriate means such as for example means for recognizing shapes or detecting a particular arrangement on the pile of the polarizing type, or by the intervention of the operator who, from his driving position, can correct the orientation of the pile according to its orientation planned on the planting line. . .
Lorsque le pieu à été correctement orienté, par une opération de rotation, le chapeau 31 est remis en position inactive, comme représenté figure 9, et l'opération de plantation peut commencer. A cet effet, la tête 13 et le système de pinces 14, qui sont portés par le mât 16, sont déportés latéralement. Le mât 16 est solidaire, par son axe de roulis 18, de la structure 17 constituée de glissières et en particulier d'une glissière supérieure 47 et d'une glissière inférieure 48. Les glissières permettent de déporter latéralement le mât 16, par rapport à la machine de plantation et par rapport au plan des roues de la machine. La position du mât 16 est réglable par pivotement autour de son axe de roulis 18 sous l'effet du vérin 19 interposé entre la structure à glissières et ledit mât. Le mât peu encore être déplacé sous l'effet du vérin 10 qui permet de faire basculer l'ensemble de l'enfonce-pieux autour de l'axe de tangage 9.When the pile has been correctly oriented, by a rotation operation, the cap 31 is returned to the inactive position, as shown in FIG. 9, and the planting operation can begin. To this end, the head 13 and the clamp system 14, which are carried by the mast 16, are offset laterally. The mast 16 is integral, by its roll axis 18, with the structure 17 consisting of slides and in particular an upper slide 47 and a lower slide 48. The slides allow the mast 16 to be offset laterally, relative to the planting machine and in relation to the plane of the machine wheels. The position of the mast 16 is adjustable by pivoting about its roll axis 18 under the effect of the jack 19 interposed between the slide structure and said mast. The mast can still be moved under the effect of the jack 10 which makes it possible to tilt the entire pile driver around the pitch axis 9.
Lors de son mouvement de translation, le pieu 15 qui est maintenu dans le système de pinces 14, s'échappe du bac récepteur 21.During its translational movement, the pile 15 which is held in the clamp system 14, escapes from the receiving tank 21.
Le transfert des pieux 15 du magasin 20 jusqu'à l'enfonce-pieux et en particulier dans le bac récepteur 21 , est schématisé figures 11 à 16. La figure 11 représente, sous forme de schéma fonctionnel, l'ensemble des moyens mis en œuvre pour transférer les pieux 15 stockés dans le magasin 20, jusque dans la zone d'influence de l'enfonce-pieux et en particulier jusqu'au bac récepteur 21 qui se situe sous la tête de l'enfonce-pieux lorsque ce dernier est dans sa position normale d'attente et de chargement d'un pieu 15.The transfer of the piles 15 from the magazine 20 to the pile driver and in particular into the receiving tank 21 is shown diagrammatically in FIGS. 11 to 16. FIG. 11 represents, in the form of a functional diagram, all of the means used to transfer the piles 15 stored in the magazine 20, as far as the area of influence of the pile driver and in particular up to the tank receiver 21 which is located under the head of the pile driver when the latter is in its normal position for waiting and loading a pile 15.
Le magasin 20 comporte un fond 50 avec des parois latérales longitudinales 51 , 52, qui s'étendent verticalement, et une paroi frontale 23 ainsi qu'une paroi arrière 54.The magazine 20 has a bottom 50 with longitudinal side walls 51, 52, which extend vertically, and a front wall 23 as well as a rear wall 54.
La capacité du magasin est telle qu'elle permet de loger entre 100 et 1000 pieux selon leurs forme et dimensions.The capacity of the store is such that it can accommodate between 100 and 1000 piles depending on their shape and dimensions.
Le fond 50 du magasin se présente sous la forme d'un dièdre comme représenté figure 1 et figures 14 et 16. L'arête du dièdre du fond 50 se situe dans un plan longitudinal vertical 55 qui constitue le plan de chargement des pieux sur l'enfonce-pieux et en particulier sous la tête 1.3. On trouve également dans ce plan 55, le bac récepteur 21.The bottom 50 of the magazine is in the form of a dihedral as shown in FIG. 1 and FIGS. 14 and 16. The edge of the dihedral of the bottom 50 is located in a vertical longitudinal plane 55 which constitutes the plane of loading of the piles on the 'post driver and in particular under the head 1.3. Also found in this plane 55, the receiving tank 21.
Selon une variante de réalisation, représentée figures.17 et 18, le magasin reçoit lés pieux 15 dans une structure en forme d'auge constituée de sangles 91 au nombre de trois par exemple, selon les nécessités. Ces sangles 91 sont fixées à la partie supérieure de la paroi latérale 51 qui se situe du côté du poste de conduite 3 et elles s'étendent jusqu'à un dispositif enrouleur 92 situé à la partie inférieure de l'autre côté du magasin 20 en passant par des galets 93 qui forment une sorte de rebord qui dessert le système de prélèvement 56 détaillé plus loin.According to an alternative embodiment, represented in FIGS. 17 and 18, the magazine receives the piles 15 in a trough-like structure made up of straps 91 three in number for example, as required. These straps 91 are fixed to the upper part of the side wall 51 which is located on the side of the driving position 3 and they extend to a winding device 92 located in the lower part on the other side of the magazine 20 in passing through rollers 93 which form a sort of rim which serves the sampling system 56 detailed below.
La figure 17 ne montre que les structures porteuses des sangles sans représentation de ces dernières. On retrouve les moyens d'accrochage et de maintien des sangles disposés à la partie supérieure de la paroi latérale 51. On retrouve également le dispositif enrouleur 92 mû par un moteur hydraulique 93 situé à la partie avant du magasin 20. On remarque également les galets 93 disposés par couples qui forment une sorte de rebord en amont du système de. prélèvement des pieux. Toujours figure 17, on remarque, des roulettes disposées à l'opposé des galets 93 par rapport au système de prélèvement 56. Ces roulettes 95 sont montées sur la paroi latérale 52 et elles empiètent sur le parcours du système de prélèvement 56, de façon à éjecter une barre qui se serait positionnée en double sur ledit système. Ces roulettes 95 sont montées souples, articulées sur la paroi 52 au moyen d'un axe 96 avec un ressort 97 interposé entre les deux de façon à pouvoir s'escamoter automatiquement lors du passage du système de prélèvement 56.Figure 17 shows only the supporting structures of the straps without representation of the latter. We find the means for hooking and holding the straps disposed at the upper part of the side wall 51. We also find the winder device 92 driven by a hydraulic motor 93 located at the front of the magazine 20. We also note the rollers 93 arranged in pairs which form a sort of rim upstream of the system. pile removal. Still in FIG. 17, it can be seen that the rollers arranged opposite the rollers 93 with respect to the removal system 56. These rollers 95 are mounted on the side wall 52 and they encroach on the path of the sample 56, so as to eject a bar which would have positioned itself twice on said system. These rollers 95 are mounted flexible, articulated on the wall 52 by means of an axle 96 with a spring 97 interposed between the two so as to be able to retract automatically during the passage of the sampling system 56.
Dans cette variante de réalisation figures 17 et 18, on remarque que le système de prélèvement ne traverse pas la masse des pieux mais se contente d'enlever les pieux au fur et à mesure qu'ils sont présentés au système de prélèvement détaillé ci-après, grâce à la déformation de l'auge par enroulement des sangles 91 formant ladite auge.In this variant of Figures 17 and 18, we note that the sampling system does not cross the mass of the piles but is content to remove the piles as and when they are presented to the sampling system detailed below , thanks to the deformation of the trough by winding the straps 91 forming said trough.
Figure 17, on remarque également des panneaux 98 disposés transversalement dans le magasin et qui permettent de caler les pieux 15 selon leur longueur.Figure 17, there are also panels 98 arranged transversely in the store and which allow the piles 15 to be wedged along their length.
Les pieux sont prélevés un par un dans le magasin 20 au moyen d'un système 56 qui se déplace dans le plan vertical 55, selon le mode de réalisation, le système de prélèvement part du fond du magasin pour élever le pieu 15 engagé sur ledit système 56, lui faisant traverser la masse des pieux logés dans ledit magasin pour l'amener à la partie supérieure de ce dernier et l'évacuer vers le bac récepteur 21. Ce mode de réalisation correspond au magasin représenté figures 1 , 6, 7 et 8.The piles are taken one by one from the magazine 20 by means of a system 56 which moves in the vertical plane 55, according to the embodiment, the sampling system starts from the bottom of the magazine to raise the pile 15 engaged on said system 56, making it pass through the mass of piles housed in said store to bring it to the upper part of the latter and evacuate it to the receiving tank 21. This embodiment corresponds to the store shown in FIGS. 1, 6, 7 and 8.
Selon le second mode de réalisation représenté figures 17 et 18, le système de prélèvement évite cette traversée de la masse des pieux tout en conservant la même structure et le même fonctionnement.According to the second embodiment represented in FIGS. 17 and 18, the sampling system avoids this crossing of the mass of the piles while retaining the same structure and the same operation.
Le système 56 de prélèvement des pieux dans le magasin comprend une poutre 57 guidée à chacune de ses extrémités dans des glissières 58 et 59 aménagées respectivement sur les parois avant 23 et arrière 54 du magasin. Cette poutre 57 se déplace parallèlement à elle-même dans le plan 55, sur toute la hauteur du magasin au moyen par exemple d'un système de compas 60 comportant une branche 61 dont l'extrémité inférieure est articulée sur le châssis 1 de la machine autour d'un axe 62 et dont l'autre branche 63, articulée en son milieu par un axe 64 sur ladite branche 61, est guidée à son extrémité inférieure, dans un rail 65 solidaire du châssis 1 , au moyen d'un galet 66, lequel galet est manœuvré au moyen d'un vérin 67.The system 56 for removing piles from the magazine comprises a beam 57 guided at each of its ends in slides 58 and 59 arranged respectively on the front 23 and rear walls 54 of the magazine. This beam 57 moves parallel to itself in the plane 55, over the entire height of the magazine by means for example of a compass system 60 comprising a branch 61 whose lower end is articulated on the chassis 1 of the machine around an axis 62 and of which the other branch 63, articulated in its middle by an axis 64 on said branch 61, is guided at its lower end, in a rail 65 secured to the chassis 1, by means of a roller 66, which roller is operated by means of a jack 67.
L'extrémité supérieure de la branche 61 est guidée dans un rail 68 aménagé à l'extrémité avant de la poutre 57, par l'intermédiaire d'un galet 69. L'extrémité supérieure de la branche 63 est articulée au moyen d'un axe 70 à l'extrémité arrière de la poutre 57.The upper end of the branch 61 is guided in a rail 68 arranged at the front end of the beam 57, by means of a roller 69. The upper end of the branch 63 is articulated by means of a axis 70 at the rear end of the beam 57.
La poutre 57 se présente sous la forme d'un profilé en H dont la partie inférieure de l'extrémité avant est aménagée en forme de rail 68, et dont la partie supérieure est aménagée sur toute sa longueur, en forme de berceau pour accueillir la structure de prélèvement des piquets 15.The beam 57 is in the form of an H-shaped section, the lower part of the front end of which is arranged in the form of a rail 68, and the upper part of which is arranged over its entire length, in the form of a cradle to accommodate the picket structure 15.
Cette structure de prélèvement repérée 71 figure 11, comprend un profil 72 en forme de Vé ouvert vers le haut, lequel Vé est par exemple renforcé sur toute sa longueur par une poutre 73 à section en U.This sampling structure identified 71 in FIG. 11 includes a profile 72 in the shape of a Vee open at the top, which Vee is for example reinforced over its entire length by a beam 73 with a U section.
La largeur du Vé 72 correspond sensiblement à la largeur de la poutre 57 et l'ensemble est guidé à chacune de ses extrémités, dans les glissières 58 et 59.The width of the V 72 corresponds substantially to the width of the beam 57 and the assembly is guided at each of its ends, in the slides 58 and 59.
. A son extrémité avant, la poutre 73 supportant le.Vé 72, est articulée sur la poutre 57 au moyen d'un axe 75, et elle comporte, au-delà dudit axe, Un prolongement en forme de doigt 76. Ce doigt 76 permet, en coopération avec une butée 77 disposée à la partie supérieure de la glissière 58, de faire basculer la structure de prélèvement 71 sur laquelle on trouve un pieu 15, lequel pieu s'échappe de ladite structure, par simple gravité, pour se poser dans le bac récepteur 21 comme représenté figure 11.. At its front end, the beam 73 supporting the.Vee 72, is articulated on the beam 57 by means of an axis 75, and it comprises, beyond said axis, a finger-shaped extension 76. This finger 76 allows , in cooperation with a stopper 77 disposed at the upper part of the slide 58, to tilt the sampling structure 71 on which there is a pile 15, which pile escapes from said structure, by simple gravity, to land in the receiving tank 21 as shown in FIG. 11.
Ce basculement et la vidange de la structure de prélèvement 71 s'effectuent automatiquement lorsque la poutre 57 atteint sa position maximale relevée à la partie supérieure du magasin, sous l'effet du vérin de manœuvre 65. L'angle de basculement du Vé est de l'ordre de 45° par rapport à l'horizontale.This tilting and emptying of the sampling structure 71 takes place automatically when the beam 57 reaches its maximum raised position at the upper part of the magazine, under the effect of the actuating cylinder 65. The tilting angle of the V is about 45 ° from the horizontal.
Le pieu 15 est guidé entre le Vé 72 et le bac 21 au moyen d'un toboggan 79 qui fait par exemple un angle de 60° par rapport à l'horizontale. Ce toboggan 79 comprend, dans sa partie supérieure, une première portion 80 en forme de guide comportant, par exemple, des flancs ou une paire de patins garnis d'un matériau du genre caoutchouc pour à la fois guider et freiner le pieu 15. La deuxième portion 81 du toboggan, située entre la première portion 80 et le bac récepteur 21, est constituée d'une goulotte 82 dont la partie inférieure est articulée au moyen d'un axe 83 sur l'extrémité avant du châssis 1. Un vérin de manœuvre 84 interposé. entre le châssis 1 et le volet 82 permet de faire basculer ce dernier entre une position de guidage du pieu 15 pendant sa mise en place gravitaire dans le bac récepteur 21 et une position de relèvement dudit pieu 15 pour le présenter au système de pinces 14 de l'enfonce-pieux.The pile 15 is guided between the V 72 and the tank 21 by means of a slide 79 which for example makes an angle of 60 ° relative to the horizontal. This slide 79 comprises, in its upper part, a first portion 80 in the form of a guide comprising, for example, sides or a pair of pads furnished with a rubber-like material to both guide and brake the pile 15. The second portion 81 of the slide, located between the first portion 80 and the receiving tank 21, consists of a chute 82, the lower part of which is articulated by means of an axis 83 on the front end of the chassis 1. A jack maneuver 84 interposed. between the frame 1 and the flap 82 makes it possible to switch the latter between a position for guiding the pile 15 during its gravity positioning in the receiving tank 21 and a position for raising said pile 15 in order to present it to the clamp system 14 of the post drivers.
La goulotte 82 est représentée en trait fort pour sa position de guidage du pieu 15 et en traits mixtes fins dans la position de basculement dudit pieu 15. On remarque, dans le fond du bac récepteur 21 , un capteur 86 qui permet de détecter la présence d'un pieu au niveau dudit bac. L'opération de prélèvement dans le magasin est contrôlée à partir des informations reçues du capteur 86, le tout géré par un automate.The chute 82 is shown in solid lines for its position for guiding the pile 15 and in thin broken lines in the tilting position of said pile 15. We note, in the bottom of the receiving tank 21, a sensor 86 which makes it possible to detect the presence of a stake at the level of said tank. The picking operation in the store is controlled from information received from the sensor 86, all managed by an automatic machine.
Cette information provenant du capteur 86, peut aussi être complétée par une information de départ du piquet 15, lorsque ce dernier est entraîné par le système de pinces 14, hors du bac 21, pour l'opération de plantation.This information from the sensor 86 can also be supplemented by information from the start of the stake 15, when the latter is driven by the clamp system 14, out of the tank 21, for the planting operation.
Dans certains cas en effet, et en particulier pour des poteaux 15 dont la section est en forme d'oméga comme représenté figure 4, le système de prélèvement 71 peut faire sortir du magasin, une paire de pieux 1.5 imbriqués l'un dans l'autre.In some cases, in fact, and in particular for posts 15 whose cross section is in the shape of an omega, as shown in FIG. 4, the sampling system 71 can bring out of the store, a pair of piles 1.5 nested one in the other.
A cet effet, la structure de prélèvement 71 et en particulier le Vé 72, comporte une paire d'électro-aimants 88, l'un était situé à l'avant et l'autre à l'arrière dudit Vé.To this end, the sampling structure 71 and in particular the Vee 72, comprises a pair of electromagnets 88, one was located at the front and the other at the rear of said Vee.
Ces électro-aimants 88 sont activés avant le basculement de la structure 71 de façon à retenir le pieu qui est en contact avec eux. L'autre pieu qui est simplement imbriqué, va s'échapper automatiquement par gravité, de la structure de prélèvement dès que cette structure, comme représenté figure 11 , sera dans la position de libération du pieu 15. Le pieu qui est libre s'échappe de la structure 71 et il prend place dans le bac 21 alors que l'autre pieu est retenu par les électro- aimants 88.These electromagnets 88 are activated before the tilting of the structure 71 so as to retain the pile which is in contact with them. The other pile, which is simply nested, will escape automatically by gravity, from the sampling structure as soon as this structure, as shown in FIG. 11, will be in the position of release of the pile 15. The pile which is free escapes of the structure 71 and it takes place in the tank 21 while the other pile is retained by the electromagnets 88.
Le premier pieu placé dans le bac 21, est pris en charge par le système de pinces 14 de l'enfonce-pieux, lequel système de pinces évacue ensuite le pieu en question pour réaliser l'opération de plantation et cette évacuation est détectée par le capteur 87. L'information du capteur 87 peut aussi permettre, de façon automatique, de commander la désactivation des électro-aimants 88 qui libèrent le second pieu resté dans la structure de prélèvement 71 , lequel second pieu prend place dans le bac récepteur 21 pour l'opération de plantation suivante.The first pile placed in the tank 21 is supported by the gripper system 14 of the pile driver, which gripper system then evacuates the pile by question for carrying out the planting operation and this evacuation is detected by the sensor 87. The information from the sensor 87 can also make it possible, automatically, to control the deactivation of the electromagnets 88 which release the second pile remaining in the structure 71, which second pile takes place in the receiving tank 21 for the next planting operation.
Lorsque la structure de prélèvement 71 est déchargée, la poutre 57 redescend comme représenté figure 13, sous l'effet du vérin 67 qui est un vérin double effet. La poutre 57 et le compas 60 et en particulier les branches 61 et 63 redescendent en traversant la masse des piquets 15 logés dans le magasin. Pour éviter l'accrochage de pieux sur la structure du compas 60 et/ou la poutre 57, on remarque la présence d'un jeu de biellettes 90 qui permettent de maintenir un certain écart entre les pieux situés de part et d'autre du compas 60.When the sampling structure 71 is unloaded, the beam 57 descends as shown in FIG. 13, under the effect of the jack 67 which is a double acting jack. The beam 57 and the compass 60 and in particular the branches 61 and 63 descend by crossing the mass of the stakes 15 housed in the store. To avoid the attachment of piles on the structure of the compass 60 and / or the beam 57, we note the presence of a set of rods 90 which allow to maintain a certain gap between the piles located on either side of the compass 60.
La figure 12 représente, de façon schématique, les. biellettes 90 disposées de part et d'autre de la branche 61 du compas. La largeur prise au niveau des biellettes 90 correspond sensiblement à la largeur de la poutre 57.FIG. 12 schematically represents the. rods 90 arranged on either side of the branch 61 of the compass. The width taken at the level of the rods 90 corresponds substantially to the width of the beam 57.
Un jeu de biellettes 90 peut être installé entre les extrémités avant et arrière des branches du compas 60.A set of rods 90 can be installed between the front and rear ends of the arms of the compass 60.
La figure 14 montre le système de prélèvement 56 en position escamotée sous le fond 50 du magasin 20. La figure 16 montre le système de prélèvement dans une position intermédiaire lors de l'élévation d'un piquet 15 posé dans le Vé 72, à travers la masse des piquets contenus dans le magasin 20.FIG. 14 shows the sampling system 56 in the retracted position under the bottom 50 of the magazine 20. FIG. 16 shows the sampling system in an intermediate position when raising a stake 15 placed in the V 72, through the mass of the stakes contained in the magazine 20.
Les piquets 15 contenus dans le magasin s'écartent et se déplacent au fur et à mesure de la montée du système de prélèvement ce qui permet, à chaque opération de prélèvement, de remuer les piquets, et de les maintenir toujours en position alignée longitudinalement, parallèlement au plan 55.The stakes 15 contained in the magazine move apart and move as the picking system rises, which makes it possible, with each picking operation, to stir the stakes, and to always keep them in position longitudinally aligned, parallel to plane 55.
Dans le cas des vignes, la plantation s'effectue comme représenté figure 19, au moyen d'un quadrillage dont la maille se présente sous la forme d'un quadrilatère en forme de parallélogramme, de carré, ou de rectangle. La plantation peut démarrer à partir d'un point O et s'effectuer selon des lignes parallèles entre elles orientées selon OA et selon OB. Pour obtenir sur le terrain un quadrillage parfaitement régulier, il est possible d'utiliser les techniques de radio-positionnement, comme représenté figure 20, soit par l'utilisation du GPS c'est-à-dire au moyen d'un guidage par satellite, soit par l'utilisation d'une station de guidage. La machine est équipée d'un système récepteur 100 associé à un dispositif d'asservissement 101. Le système récepteur reçoit les informations provenant soit d'un satellite 101 pour le système GPS, soit d'une station fixe 102. Dans le cas du système GPS, les informations et coordonnées par l'interrogation des satellites, sont transmises par le système de réception 100 vers l'automate 101 , lequel automate traite les données pour fixer le point de plantation des pieux.In the case of vines, the planting is carried out as shown in Figure 19, by means of a grid whose mesh is in the form of a quadrilateral in the form of parallelogram, square, or rectangle. The planting can start from a point O and be carried out according to parallel lines between them oriented according to OA and according to OB. To obtain a perfectly regular grid on the ground, it is possible to use radio positioning techniques, as shown in Figure 20, either by the use of GPS, that is to say by means of satellite guidance. , or by the use of a guidance station. The machine is equipped with a receiving system 100 associated with a servo device 101. The receiving system receives information coming either from a satellite 101 for the GPS system, or from a fixed station 102. In the case of the system GPS, the information and coordinates by interrogating the satellites, are transmitted by the reception system 100 to the automaton 101, which automaton processes the data to fix the planting point of the piles.
Dans le cas d'un guidage au moyen d'une station 103, la machine comporte, en plus, un prisme 104 installé sur l'enfonce-pieux et en particulier à la. verticale de la cloche de la tête 13, c'est-à-dire à la verticale du lieu de positionnement du pieu. Ce prisme permet à la station 1.03, après étalonnage, de positionner correctement le véhicule au niveau de chaque point de plantation.In the case of guidance by means of a station 103, the machine further comprises a prism 104 installed on the post driver and in particular at the. vertical of the bell of the head 13, that is to say vertical to the location of the pile. This prism allows the station 1.03, after calibration, to correctly position the vehicle at each planting point.
Ce guidage peut s'effectuer soit de façon informatisée au moyen d'un, programme de plantation préétabli, soit de façon automatisée par intervention ponctuelle de l'opérateur pour réaliser un déplacement de point en point sur une même ligne ou pour se décaler sur la ligne suivante. L'utilisation des moyens d'asservissement et de guidage permet de réaliser une plantation des piquets avec une très grande précision, au centimètre près ce qui facilite le passage des autres engins comme les engins de traitement et de récolte. This guidance can be done either computerized by means of a pre-established planting program, or automatically by occasional operator intervention to move from point to point on the same line or to shift onto the next line. The use of slaving and guiding means makes it possible to plant stakes with very high precision, to the nearest centimeter, which facilitates the passage of other machines such as processing and harvesting machines.
