Description

La présente invention concerne un procédé et une machine pour douver les tourets.The present invention relates to a method and a machine for raking drums.

Il est habituel de stocker et de transporter les câbles électriques, de traction ou autres en les enroulant sur des tambours munis à chaque extrémité de joues en forme de roue et appelés tourets.It is usual to store and transport electrical, traction or other cables by winding them on drums fitted at each end with cheeks in the shape of a wheel and called reels.

On entend par "douver un touret" le fait de protéger un touret en clouant sur toute la circonférence du touret une suite de planches juxtaposées, le clouage des planches se faisant sur les joues du touret, et de cercler l'ensemble par des rubans d'acier.By "finding a reel" is meant protecting a reel by nailing around the entire circumference of the reel a series of juxtaposed boards, the nailing of the boards being done on the cheeks of the reel, and of encircling the whole with ribbons of 'steel.

Actuellement, la pose des planches sur le touret et leur clouage se font manuellement une par une.Currently, the laying of the boards on the reel and their nailing are done manually one by one.

Le document de brevet US-A 1 717 834 décrit un procédé pour douver un touret dans lequel on commence par poser et clouer une latte sur les joues du touret puis ensuite, on cloue sur ces lattes deux sangles, respectivement à quelque distance des deux joues latérales du touret. Les autres planches sont ensuite placées successivement, sans les clouer, entre les joues du touret et les sangles en se servant des sangles, suffisamment tendues pour bien appliquer les lattes une à une contre les joues du touret. Une fois le tour complet terminé et toutes les lattes placées, on exerce, sur un câble que l'on passe autour du touret en son milieu, une forte traction de façon à incurver toutes les lattes de manière à leur donner une forme concave, les sangles sont alors tendues puis scellées à recouvrement sur les extrémités fixées à la première latte. Le câble de traction est alors ôté.The patent document US-A 1 717 834 describes a process for finding a reel in which one starts by placing and nailing a batten on the cheeks of the reel then then, two straps are nailed to these slats, respectively at some distance from the two cheeks side of the drum. The other boards are then placed successively, without nailing them, between the cheeks of the reel and the straps using the straps, sufficiently tightened to properly apply the slats one by one against the cheeks of the reel. Once the complete revolution is complete and all the slats have been placed, a strong pull is exerted on a cable which is passed around the reel in order to bend all the slats so as to give them a concave shape, the straps are then stretched and then sealed overlapping on the ends fixed to the first slat. The traction cable is then removed.

Ce procédé permet de serrer fortement les lattes contre le touret et d'éviter de clouer les planches sur les joues et ainsi d'abîmer ces joues. Cependant, si ce procédé permet de bien appliquer les lattes sur le touret, il ne garantit en aucune façon le bon jointoiement des lattes les unes contre les autres et encore moins leur serrage.This process makes it possible to tighten the slats firmly against the reel and to avoid nailing the boards on the cheeks and thus damaging these cheeks. However, if this method allows the slats to be properly applied on the reel, it does not in any way guarantee the proper jointing of the slats against each other and even less their tightening.

Or il est parfois nécessaire, lors de transports lointains et/ou dans des conditions difficiles, que ces lattes soient parfaitement jointives. En outre, dans ce document, la pose des lattes et l'opération en général est manuelle.However it is sometimes necessary, during distant transport and / or in difficult conditions, that these slats are perfectly contiguous. In addition, in this document, the installation of the slats and the operation in general is manual.

L'invention se propose de réaliser un procédé et une machine automatique pour douver les tourets, procédé dans lequel les planches sont fortement serrées les unes contre les autres de manière à ne pas laisser de vide entre chaque planche.The invention proposes to carry out a method and an auto machine matic to check the reels, process in which the boards are tightly pressed against each other so as not to leave a vacuum between each board.

La présente invention a ainsi pour objet un procédé pour douver un touret comportant un tambour et des joues latérales, au moyen d'une suite de planches jointives, l'ensemble étant en outre cerclé par au moins deux rubans d'acier, procédé dans lequel on procède comme suit :

  • a/ - on pose et on cloue un petit nombre limité de planches, au moins une, sur les joues du touret ;
  • b/ - on cloue une extrémité de chaque ruban d'acier sur au moins la première desdites planches, respectivement à quelque distance des deux joues latérales du touret ;
  • c/ - on place successivement les autres planches à la suite des premières, sans les clouer, en se servant des rubans d'acier comme magasin support, ledit ruban entourant, selon un tour complet le touret, et les planches étant placées les unes à côté des autres entre la circonférence des deux joues et les rubans d'acier, caractérisé en ce que les rubans d'acier entourent le touret selon un diamètre légèrement supérieur à celui des joues du touret augmenté de deux fois l'épaisseur des planches et en ce que,
  • d/ - une fois toutes les planches placées, dont le nombre est prédéterminé à l'avance et qui, compte tenu de la tolérance sur le diamètre des tourets, est au moins égal au nombre de planches que l'on peut naturellement placer tout autour du touret plus une, on exerce un effort suffisant de traction sur lesdits rubans d'acier de manière à resserrer toutes les planches de façon à ce qu'elles s'appuient toutes sur les joues du touret ;
  • e/ - on cloue la partie libre des rubans en recouvrement sur les extrémités déjà clouées sur les premières planches, puis on coupe les bandes.
The subject of the present invention is thus a method for testing a reel comprising a drum and side cheeks, by means of a series of adjoining boards, the assembly being further surrounded by at least two steel strips, method in which we proceed as follows:
  • a / - a limited number of boards, at least one, are laid and nailed to the cheeks of the drum;
  • b / - one end of each steel strip is nailed to at least the first of said boards, respectively at some distance from the two lateral cheeks of the drum;
  • c / - the other boards are placed successively after the first, without nailing them, using the steel ribbons as a support store, said ribbon surrounding, according to a complete revolution, the reel, and the boards being placed one at a time side of the others between the circumference of the two cheeks and the steel ribbons, characterized in that the steel ribbons surround the drum with a diameter slightly greater than that of the drum cheeks increased by twice the thickness of the boards and what,
  • d / - once all the boards have been placed, the number of which is predetermined in advance and which, taking into account the tolerance on the diameter of the drums, is at least equal to the number of boards which can naturally be placed all around of the drum plus one, a sufficient tensile force is exerted on said steel strips so as to tighten all the boards so that they all rest on the cheeks of the drum;
  • e / - we nail the free part of the overlapping ribbons on the ends already nailed on the first boards, then we cut the strips.

Par mesure de sécurité, on peut avantageusement clouer au moins quelques planches sur les joues du touret et, par endroit, les rubans d'acier sur les planches.As a safety measure, it is advantageous to nail at least a few boards on the cheeks of the reel and, in places, the steel ribbons on the boards.

Selon une variante, on inverse les opérations a et b c'est-à-dire que l'on commence par poser successivement des planches sur les joues du touret en clouant une extrémité de chaque ruban d'acier sur un petit nombre limité de ces planches : au moins sur la première, respectivement à quelque distance des deux joues latérales du touret ; on cloue ensuite au moins la première desdites planches sur les joues du touret.According to a variant, the operations a and b are reversed, that is to say that one begins by successively placing planks on the cheeks of the reel by nailing one end of each steel strip on a small limited number of these boards: at least on the first, respectively at some distance from the two lateral cheeks of the reel; then at least the first of said boards is nailed to the cheeks of the drum.

Avantageusement, lors desdites opérations a et b, réalisées dans cet ordre ou inversées selon ladite variante, le touret est entraîné en rotation, lesdites planches étant posées successivement sur la génératrice supérieure du touret.Advantageously, during said operations a and b, carried out in this order or reversed according to said variant, the reel is driven in rotation, said boards being placed successively on the upper generator of the reel.

Selon une réalisation préférée du procédé on procède comme suit pour l'opération c :

  • On entraîne en rotation le touret pendant que l'on place les unes à la suite des autres les planches, en partant de celles qui sont déjà clouées et en les appliquant les unes contre les autres ; en même temps, on fait avancer les rubans d'acier dans le"sens correspondant à leur enroulement par la rotation du touret mais avec une vitesse linéaire légèrement supérieure à la vitesse tangentielle de l'extrémité des rubans d'acier clouée sur la première planche selon l'opération b précédente.
According to a preferred embodiment of the method, the procedure for operation c is as follows:
  • The reel is driven in rotation while the boards are placed one after the other, starting from those which are already nailed and applying them against each other; at the same time, the steel strips are advanced in the "direction corresponding to their winding by the rotation of the reel but with a linear speed slightly greater than the tangential speed of the end of the steel strips nailed to the first board according to the previous operation b.

  • FIGS. 1A to 1F illustrate the different steps of the method according to the invention. In FIG. 1A, we can see a drum 1 which has been lifted from its cell 2, made in the ground 3, and rotated in the direction of an arrow 4.

Au-dessus du touret, on voit l'une 5a de deux cloueuse pour clouer des rubans d'acier sur les planches et l'une 6a de deux cloueuses pour clouer les planches sur les joues latérales 7, 8 (figure 6) du touret. En 9, on voit un guide d'amenée d'un 10a de deux rubans d'acier 10a, 10b. Un convoyeur 11 apporte des planches 12 jusqu'à une butée d'arrêt 13. Des bras transferts 14a, 14b permettent de prendre la planche 12a située contre la butée 13 afin de la placer sur la génératrice supérieure des joues du touret, comme on le voit sur la figure 1B. Cette planche est alors clouée au moyen de cloueuses 6a et 6b. Le touret 1 continuant à tourner, les bras transferts 14a, 14b placent ainsi quelques planches les unes à la suite des autres, par exemple trois, sur le touret, lesquelles sont immédiatement clouées au moyen des eloueuses 6a et 6b. Lorsque la première planche 12a arrive au droit des cloueuses 5a et 5b (figure 1C), des rubans d'acier 10a, 10b entraînés par des galets 15, 16 sont cloués sur cette première planche et éventuellement aussi sur les deux suivantes. Ensuite, le touret tournant toujours, les bras transferts 14a, 14b continuent à placer des planches les unes à la suite des autres contre les précédentes jusqu'à ce que l'on ait placé le nombre prédéterminé de planches mais sans rien clouer : ni les planches, ni les rubans. Pendant cette phase, les rubans d'acier 10a, 10b sont entraînés par les galets 15, 16 à une vitesse linéaire légèrement supérieure à la vitesse tangentielle de l'extrémité des rubans, clouée sur la première planche 12a. On arrive ainsi à la figure 1D dans laquelle on voit que les rubans 10a (10b) servent de magasin support pour les planches 12. On bloque alors les rubans d'acier 10a (10b), figure 1D, au moyen d'un dispositif de serrage 17 tout en maintenant la rotation du touret jusqu'à un effort de traction prédéterminé, ce qui a pour effet de rendre les planches parfaitement jointives en les comprimant chacune de façon à ce qu'elles s'appuient sur la circonférence des joues du touret. On cloue alors, figure 1E, au moyen des cloueuses 5a et 5b les rubans d'acier après un certain recouvrement des extrémités clouées au départ ; puis on coupe les rubans au moyen de cisailles 18.Above the reel, we see one 5a of two nailers to nail steel ribbons on the boards and one 6a of two nailers to nail the boards on the side cheeks 7, 8 (figure 6) of the reel . In 9, we see a guide for bringing a 10a of two steel strips 10a, 10b. A conveyor 11 brings boards 12 to a stop 13. Transfer arms 14a, 14b make it possible to take the board 12a situated against the stop 13 in order to place it on the upper generator of the cheeks of the drum, as is see in Figure 1B. This board is then nailed using nailers 6a and 6b. The reel 1 continuing to rotate, the transfer arms 14a, 14b thus place a few boards one after the other, for example three, on the reel, which are immediately nailed by means of the scrappers 6a and 6b. When the first board 12a arrives at the right of the nailers 5a and 5b (FIG. 1C), steel strips 10a, 10b driven by rollers 15, 16 are nailed to this first board and possibly also to the next two. Then, the reel still rotating, the transfer arms 14a, 14b continue to place boards one after the other against the previous ones until the predetermined number of boards have been placed but without nailing anything: neither the boards, nor ribbons. During this phase, the steel strips 10a, 10b are driven by the rollers 15, 16 at a linear speed slightly greater than the tangential speed of the end of the strips, nailed to the first board 12a. We thus arrive at FIG. 1D in which we see that the tapes 10a (10b) serve as a support store for the boards 12. We then block the steel tapes 10a (10b), FIG. 1D, by means of a device for tightening 17 while maintaining the rotation of the reel until a predetermined tensile force, which has the effect of making the boards perfectly joined by compressing them each so that they rest on the circumference of the cheeks of the reel . The steel strips are then nailed, in FIG. 1E, by means of the nailers 5a and 5b. after a certain overlap of the ends nailed at the start; then the ribbons are cut using shears 18.

On effectue alors un nouveau tour complet du touret, figure 1F, de façon à clouer quelques planches au moyen des cloueuses 6a et 6b par exemple une sur dix ou plus, ou moins, selon ce qui est nécessaire et de façon à clouer également sur quelques planches les rubans 10a, 10b au moyen des cloueuses 5a et 5b.A new complete turn of the reel is then carried out, FIG. 1F, so as to nail a few boards by means of nailers 6a and 6b for example one in ten or more, or less, as necessary and so as to also nail on a few planks ribbons 10a, 10b by means of nailers 5a and 5b.

La figure 2 montre en perspective une machine selon l'invention permettant de douver des tourets conformément au procédé de l'invention. Pour la clarté de la figure, un certain nombre d'éléments ont été retirés mais qui apparaissent dans les figures suivantes.FIG. 2 shows in perspective a machine according to the invention making it possible to find drums according to the method of the invention. For the sake of clarity of the figure, a certain number of elements have been removed but which appear in the following figures.

Ainsi dans cette figure 2, la machine se compose d'un bâti 19 supportée par quatre galets de roulement dont trois seulement 20, 21, et 22 sont visibles sur la figure 2, le quatrième, le galet 23 est visible sur la figure 4. Cette machine peut rouler sur une voie ferrée composée de deux rails 24 et 25. Le rail 24 arrive à fleur du sol comme le montre également la figure 4, et les galets 20 et 21 qui roulent sur ce rail ne comportent aucun organe de guidage latéral. Ce guidage est assuré par les galets 22 et 23 qui roulent sur le rail 25 lequel est placé dans une tranchée 26 laissant la place à un câble électrique 27, d'alimentation du moteur d'entraînement de la machine le long de la voie ferrée, ainsi que pour l'alimentation de divers autres circuits de commande ou de puissance, par exemple l'alimentation d'un moteur pour l'entraînement d'un compresseur pour les cloueuses. Ce câble 27 a une extrémité fixe située en extrémité de la voie ferrée, extrémité 28 par exemple, figure 11, et son autre extrémité s'enroule sur un tambour, non représenté, monté sur le bâti 19 de la machine, le câble s'enroulant et se déroulant au rythme des mouvements de la machine le long de la voie.Thus in this FIG. 2, the machine consists of a frame 19 supported by four rollers, only three of which 20, 21, and 22 are visible in FIG. 2, the fourth, the roller 23 is visible in FIG. 4. This machine can run on a railroad track made up of two rails 24 and 25. The rail 24 arrives flush with the ground as also shown in FIG. 4, and the rollers 20 and 21 which roll on this rail have no lateral guide member . This guidance is provided by the rollers 22 and 23 which roll on the rail 25 which is placed in a trench 26 giving way to an electric cable 27, supplying the drive motor of the machine along the railroad track, as well as for the supply of various other control or power circuits, for example the supply of a motor for driving a compressor for nailers. This cable 27 has a fixed end located at the end of the railway, end 28 for example, FIG. 11, and its other end is wound on a drum, not shown, mounted on the frame 19 of the machine, the cable s' winding and unwinding at the rate of movement of the machine along the track.

Sur le bâti 19 est monté un magasin à planches 29 lequel comprend un plateau 30 recevant les planches 12 (figure 3). Ce plateau 30 peut monter et descendre dans le magasin 29 grâce à un vérin 31. Dans ce magasin les planches sont placées par couches horizontales successives, les planches étant disposées perpendiculairement à la voie ferrée.On the frame 19 is mounted a plank magazine 29 which comprises a plate 30 receiving the planks 12 (Figure 3). This plate 30 can go up and down in the magazine 29 by means of a jack 31. In this magazine, the boards are placed in successive horizontal layers, the boards being arranged perpendicular to the railroad tracks.

Au bâti 19 est lié le convoyeur 11. Ce convoyeur est destiné à recevoir les planches 12 du magasin 29 et à les amener jusqu'à une butée 13 en fin de convoyeur (figure 9). Un bras auxiliaire 32, visible sur les figures 2 et 3, permet de prendre les planches dans le magasin 29 et de les poser sur le convoyeur 11. Ce bras peut pivoter de 180° autour d'un axe 33 vertical. Sur la figure 3, ce bras est représenté en traits continus forts dans sa position située au-dessus du magasin 29 et en traits discontinus dans sa position au-dessus du convoyeur 11. Le bras auxiliaire 32 est muni de deux règles 33a et 33b parallèles, horizontales, et perpendiculaires au bras 32. Ces règles sont suspendues sous le bras 32 par des supports pivotants 34a et 34b. Ces supports sont actionnés par des vérins 35a et 35b.The conveyor 11 is linked to the frame 19. This conveyor is intended to receive the boards 12 from the magazine 29 and to bring them up to a stop 13 at the end of the conveyor (FIG. 9). An auxiliary arm 32, visible in FIGS. 2 and 3, makes it possible to take the boards from the magazine 29 and place them on the conveyor 11. This arm can pivot 180 ° around a vertical axis 33. In FIG. 3, this arm is shown in solid continuous lines in its position above the magazine 29 and in broken lines in its position above the conveyor 11. The auxiliary arm 32 is provided with two parallel rulers 33a and 33b , horizontal, and perpendicular to the arm 32. These rules are suspended under the arm 32 by pivoting supports 34a and 34b. These supports are actuated by jacks 35a and 35b.

Afin de s'adapter à la longueur des planches 12 qui diffèrent selon les tourets, le support 34a de la règle 33a est accroché à un chariot 36 solidaire d'un vérin à bande 37 permettant le déplacement du chariot 36 dans un sens ou dans l'autre.In order to adapt to the length of the boards 12 which differ according to the reels, the support 34a of the rule 33a is attached to a carriage 36 secured to a band cylinder 37 allowing the carriage 36 to move in one direction or in the 'other.

Les règles 35a et 35b sont munies de griffes 38.Rules 35a and 35b are provided with claws 38.

Ainsi, le bras 32 peut ainsi prendre toute la couche supérieure des planches 12 en une seule fois et la déposer sur le convoyeur 11 après une rotation de 180° du bras 32. Automatiquement, le vérin 31 est mis en action de façon à surélever la pile de planches d'une couche dès que le bras auxiliaire a ôté la couche supérieure.Thus, the arm 32 can thus take the entire upper layer of the boards 12 at once and deposit it on the conveyor 11 after a 180 ° rotation of the arm 32. Automatically, the jack 31 is actuated so as to raise the stack of planks of a layer as soon as the auxiliary arm has removed the upper layer.

En revenant à la figure 2, et en se référant également à la figure 4, le bâti 19 supporte deux bras supports verticaux 39a et 39b. Ces bras supports sont suspendus à un arbre commun 40 sur lequel ils peuvent coulisser. Un vérin 41 permet le déplacement du bras support 39 le long de l'arbre 40 et un vérin 42 permet le déplacement du bras support 39b le long de l'arbre 40.Returning to FIG. 2, and also referring to FIG. 4, the frame 19 supports two vertical support arms 39a and 39b. These support arms are suspended from a common shaft 40 on which they can slide. A jack 41 allows the support arm 39 to move along the shaft 40 and a jack 42 allows the support arm 39b to move along the shaft 40.

Le bras support 39b porte une pointe 43 et le bras support 39a porte une contre-pointe 44. La pointe 43 comprend un moteur 45 d'entraînement en rotation et comporte des ergots 46 pour l'entraînement en rotation du touret 1 supporté par les bras supports (voir figure 3).The support arm 39b carries a tip 43 and the support arm 39a carries a tailstock 44. The tip 43 comprises a motor 45 for driving in rotation and comprises lugs 46 for driving in rotation the drum 1 supported by the arms supports (see figure 3).

La pointe 43 et la contre-pointe 44 sont déplaçables verticalement de bas en haut et vice-versa par un mécanisme à vis 47 avec guidage le long d'un arbre 48. Ainsi, la machine peut venir se placer au droit d'un touret 1 placé sur la voie ferrée (figure 11) le prendre entre pointe et contre-pointe et le hisser, compte tenu de son diamètre, à la hauteur convenable relativement aux mécanismes réalisant l'opération de douvage, représentés sur la figure 9.The tip 43 and the tailstock 44 can be moved vertically from bottom to top and vice-versa by a screw mechanism 47 with guidance along a shaft 48. Thus, the machine can be placed in line with a reel 1 placed on the railway (figure 11) take it between point and tailstock and hoisting it, taking into account its diameter, at the suitable height relative to the mechanisms carrying out the stoving operation, represented in FIG. 9.

Comme on peut le remarquer sur la figure 11, le chariot 49 apporte les tourets, du côté du rail 24 à fleur de sol et les dépose dans les alvéoles 2 en les poussant contre le bord de l'alvéole le plus proche du rail 25.As can be seen in FIG. 11, the carriage 49 brings the reels on the side of the rail 24 flush with the ground and deposits them in the cells 2 by pushing them against the edge of the cell closest to the rail 25.

Ainsi, la course latérale du bras support 39b, le long de l'arbre 40, n'est calculée que pour la pénétration de la pointe et des ergots d'entraînement 46, indépendamment de la largeur des tourets. Par contre, la course maximale prévue pour le bras support 39a tient compte des largeurs maximale et minimale des tourets.Thus, the lateral stroke of the support arm 39b, along the shaft 40, is only calculated for the penetration of the tip and the drive pins 46, regardless of the width of the drums. On the other hand, the maximum stroke provided for the support arm 39a takes account of the maximum and minimum widths of the drums.

La figure 5 montre l'intérieur de la machine selon la flèche F2 de la figure 2. Elle montre le bras support 39b et l'arrivée de l'un des deux rubans d'acier 10b se déroulant à partir d'un rouleau 50 et passant dans un guide 9 jusqu'aux galets d'entraînements 15, 16. La suite du cheminement du ruban est représenté sur la figure 9 dans laquelle on voit que l'on retrouve le guide 9 après les galets 15, 16.FIG. 5 shows the interior of the machine according to the arrow F2 in FIG. 2. It shows the support arm 39b and the arrival of one of the two steel strips 10b unwinding from a roller 50 and passing through a guide 9 to the drive rollers 15, 16. The continuation of the path of the ribbon is shown in FIG. 9 in which we see that we find the guide 9 after the rollers 15, 16.

Cette figure 5 montre en outre très schématiquement un bras transfert 14b destiné en coopération avec le bras transfert 14a (figures 6 et 9) à prendre une planche 12 en butée contre la butée 13 à l'extrémité aval du convoyeur 11 pour la placer sur le touret.This FIG. 5 also very schematically shows a transfer arm 14b intended in cooperation with the transfer arm 14a (FIGS. 6 and 9) to take a board 12 abutting against the stop 13 at the downstream end of the conveyor 11 to place it on the reel.

La figure 6 montre certains détails de la partie supérieure des bras supports 39a et 39b vus dans le sens des flèches F4 figures 2 et 5. En particulier, on a représenté l'emplacement des cloueuses 5a, 5b et 6a, 6b associées au bras support 39a.FIG. 6 shows certain details of the upper part of the support arms 39a and 39b seen in the direction of the arrows F4 FIGS. 2 and 5. In particular, the location of the nailers 5a, 5b and 6a, 6b associated with the support arm has been shown. 39a.

Comme on peut le remarquer les axes des cloueuses 6a et 6b sont en biais. Ceci permet d'assurer une meilleure fixation des planches sur le touret.As can be seen, the axes of the nailers 6a and 6b are at an angle. This ensures better fixing of the boards on the reel.

Cette figure montre aussi le système d'entraînement en rotation des galets d'entraînement 15 des rubans d'acier 10a et 10b. Les deux galets 15 sont entraînés à la même vitesse grâce à un arbre cannelé 51 solidaire du galet 15 monté sur le bras support 39b et à un manchon cannelé 52 solidaire du galet 15 monté sur le bras support 39a. Lors des déplacements relatifs des bras supports 39a et 39b le long de l'arbre 40 (figures 2, 4 et 5), l'arbre cannelé 51 et le manchon cannelé 52 glissent l'un dans l'autre.This figure also shows the system for rotating the drive rollers 15 of the steel strips 10a and 10b. The two rollers 15 are driven at the same speed thanks to a splined shaft 51 secured to the roller 15 mounted on the support arm 39b and to a splined sleeve 52 secured to the roller 15 mounted on the support arm 39a. During the relative movements of the support arms 39a and 39b along the shaft 40 (Figures 2, 4 and 5), the splined shaft 51 and the splined sleeve 52 slide one inside the other.

Le galet d'entraînement 15 monté sur le bras support 39b est entraîné en rotation par un moteur 53 par l'intermédiaire d'une courroie 54. Les galets inférieurs 16 sont montés fous.The drive roller 15 mounted on the support arm 39b is rotated by a motor 53 via a belt 54. The lower rollers 16 are mounted idly.

La vitesse de rotation du moteur 53 est réglable de manière à pouvoir donner aux rubans une vitesse linéaire supérieure à la vitesse tangentielle de l'extrémité des rubans cloués sur la première planche 12a.The speed of rotation of the motor 53 is adjustable so as to be able to give the strips a linear speed greater than the tangential speed of the end of the strips nailed to the first board 12a.

Sur ces bras supports 39a et 39b sont également montés les bras transferts 14a et 14b qui servent à prendre les planches 12 sur le convoyeur 11 et les disposer sur le touret.On these support arms 39a and 39b are also mounted the transfer arms 14a and 14b which are used to take the boards 12 on the conveyor 11 and arrange them on the reel.

Comme pour les galets 15 d'entraînement des rubans d'acier, ces bras transferts sont entraînés d'une manière synchrone grâce à un arbre cannelé 55 solidaire du bras transfert 14b monté sur le bras support 39b, et à un manchon cannelé 56 solidaire du bras transfert 14a monté sur le bras support 39a.As for the rollers 15 for driving the steel strips, these transfer arms are driven synchronously by means of a splined shaft 55 secured to the transfer arm 14b mounted on the support arm 39b, and to a splined sleeve 56 secured to the transfer arm 14a mounted on the support arm 39a.

L'arbre cannelé 55 est entraîné en rotation par un moteur 57. L'arbre cannelé 55, comme l'arbre cannelé 51 est parallèle à l'axe du touret monté entre pointe et contre-pointe.The splined shaft 55 is rotated by a motor 57. The splined shaft 55, like the splined shaft 51 is parallel to the axis of the reel mounted between tip and tailstock.

La figure 7 montre le bras transfert 14a dans le sens de la flèche F3 de la figure 6 et la figure 8 est une coupe selon VIII-VIII de la figure 7.FIG. 7 shows the transfer arm 14a in the direction of the arrow F3 in FIG. 6 and FIG. 8 is a section along VIII-VIII in FIG. 7.

Le bras transfert 14a porte à son extrémité inférieure un levier 58 articulé autour d'un axe 59, parallèle à l'arbre cannelé 55. Un vérin 60 permet de mettre en action ce levier 58. Le but de ce levier est de permettre aux bras transferts de soulever la planche arrêtée contre la butée 13 du convoyeur 11 (figure 9).The transfer arm 14a carries at its lower end a lever 58 articulated around an axis 59, parallel to the splined shaft 55. A jack 60 makes it possible to actuate this lever 58. The purpose of this lever is to allow the arms transfers to lift the stopped board against the stop 13 of the conveyor 11 (figure 9).

Enfin, au levier 58 est articulé un doigt de préhension 61 autour d'un axe 62 perpendiculaire à l'axe 59. Ce doigt est mu par un vérin 63.Finally, to the lever 58 is articulated a gripping finger 61 around an axis 62 perpendicular to the axis 59. This finger is moved by a jack 63.

La figure 9 montre l'ensemble du mécanisme : arrivée d'un ruban d'acier 10a, cloueuse 5a pour le ruban d'acier, cloueuse 6a pour les planches 12, bras transfert 14a pour l'amenée des planches sur le touret 1. Cette figure montre en outre le dispositif 17 (figure 1D) de blocage des rubans d'acier permettant d'exercer la traction nécessaire pour la mise en place définitive des planches sur le touret. Ce dispositif comporte une came 17a coopérant avec une contre came 17b. La came 17a est actionnée par un vérin 64. Cette 'figure montre également les cisailles 18 et un sabot 65 d'application du ruban contre les planches.FIG. 9 shows the entire mechanism: arrival of a steel strip 10a, nailer 5a for the steel strip, nailer 6a for the boards 12, transfer arm 14a for bringing the boards onto the reel 1. This figure also shows the device 17 (FIG. 1D) for blocking the steel strips allowing the necessary traction to be exerted. for the final installation of the boards on the drum. This device comprises a cam 17a cooperating with a counter cam 17b. The cam 17a is actuated by a jack 64. This figure also shows the shears 18 and a shoe 65 for applying the tape against the boards.

La figure 10 est une variante de la figure 9. Elle comporte les mêmes éléments avec les mêmes références. La seule différence consiste en ce que, comme on le voit, le cloueuse 6a (et évidemment la cloueuse 6b de l'autre côté) pour clouer les planches 12 sur les joues du touret est située à la place de la cloueuse 5A et vice versa. Bien évidemment, le sabot 65, les cisailles 18 et le système de blocage 17a, 17b du ruban d'acier 10a sont décalés de la même façon.Figure 10 is a variant of Figure 9. It has the same elements with the same references. The only difference is that, as we can see, the nailer 6a (and obviously the nailer 6b on the other side) to nail the boards 12 on the cheeks of the reel is located in place of the nailer 5A and vice versa . Obviously, the shoe 65, the shears 18 and the locking system 17a, 17b of the steel strip 10a are offset in the same way.

Cette disposition permet de réaliser la variante du procédé ; c'est-à-dire celle dans laquelle on commence par poser une première planche sur la génératrice supérieure du touret et à clouer sur cette planche les deux rubans d'acier 10a et 10b, à continuer de la même façon pour les deux planches suivantes et à ne clouer ces trois planches sur les joues du touret qu'après cela, lorsque ces trois premières planches arrivent successivement sous les cloueuses 6a et 6b.This arrangement makes it possible to carry out the variant of the process; that is to say the one in which we start by placing a first board on the upper generator of the reel and nailing on this board the two steel ribbons 10a and 10b, to continue in the same way for the following two boards and to nail these three boards to the cheeks of the drum only after that, when these first three boards arrive successively under the nailers 6a and 6b.

Les figures 1a à 1F décrivent le procédé dans le cas où l'on commence par clouer les trois premières planches sur le touret et ensuite seulement les rubans d'acier sur ces trois premières planches. Bien évidemment, l'homme de l'art saura inverser les opérations de manière à réaliser le procédé dans le cas de la variante correspondant à cette figure 10.Figures 1a to 1F describe the process in the case where one begins by nailing the first three boards on the reel and then only the steel strips on these first three boards. Obviously, those skilled in the art will be able to reverse the operations so as to carry out the method in the case of the variant corresponding to this figure 10.

Un avantage de cette variante, correspondant à cette figure 10, consiste dans le fait que, compte tenu de la tolérances sur les largeurs de tourets, la longueur des planches peut ne pas correspondre exactement à la largeur hors joues du touret et il faut alors centrer ces planches sur le touret. Or, compte tenu du nombre des mouvements qui se produisent au niveau de la pose des planches sur la génératrice supérieure, on a avantage à ne clouer ces planches qu'un peu plus loin, ce qui laisse du temps pour ce centrage.An advantage of this variant, corresponding to this figure 10, consists in the fact that, taking into account the tolerances on the widths of reels, the length of the boards may not correspond exactly to the width of the reel without cheeks and it is then necessary to center these boards on the reel. However, given the number of movements that occur at the level of the installation of the boards on the upper generator, it is advantageous to nail these boards only a little further, which leaves time for this centering.

La machine comporte en outre bien entendu, bien que non représentés, un compresseur et une centrale hydraulique pour la commande des moteurs hydrauliques des différents mouvements.The machine further comprises of course, although not shown, a compressor and a hydraulic unit for controlling the hydraulic motors of the different movements.

La figure 11 montre que la machine selon l'invention peut se déplacer le long de la voie ferrée 24, 25 afin de douver successivement les tourets 1 placés dans les alvéoles 2. Sur cette figure, la machine est placée en position de garage et on voit en 66 un escabeau pour permettre d'atteindre les organes supérieurs de la machine pour l'entretien et les réglages.FIG. 11 shows that the machine according to the invention can move along the railway track 24, 25 in order to successively test the drums 1 placed in the cells 2. In this figure, the machine is placed in the garage position and on sees in 66 a stepladder to allow reaching the upper parts of the machine for maintenance and adjustments.

Bien entendu, tous les organes mobiles, plateau élévateur 30, bras auxiliaire 32, bras transferts 14a, 14b, etc... comportent des arrêts de fin de course selon des techniques habituelles. De même une électronique coordonne tous les mouvements ; des moyens de détection sont prévus pour détecter la présence ou l'absence d'un touret à douver dans un alvéole 2 et selon le cas, la machine reçoit un ordre d'arrêt ou au contraire continue sa course jusqu'à l'alvéole suivant.Of course, all the movable members, lifting platform 30, auxiliary arm 32, transfer arms 14a, 14b, etc. have stop stops according to usual techniques. Similarly, electronics coordinate all movements; detection means are provided for detecting the presence or absence of a reel to be brooded in a cell 2 and, as the case may be, the machine receives a stop order or, on the contrary, continues its course to the next cell .

La figure 12 représente le pupitre de commande montrant les boutons de commande et le tableau d'affichage.Figure 12 shows the control panel showing the control buttons and the display board.

Le pupitre de commande comprend un tableau d'affichage 67 comprenant un voyant d'affichage 68 à deux chiffres, que l'on affiche grâce à des molettes 69 et 70. Ce voyant sert à indiquer à la machine le code correspondant aux dimensions des tourets à douver placés dans les alvéoles 2. Le tableau 67 comprend un autre voyant 71, également à deux chiffres, qui sert à indiquer l'état de la machine et les défauts qui peuvent survenir. A l'arrêt, le voyant 71 indique par exemple, selon un code établi d'avance, 99, et chaque défaut de tel ou tel mouvement est répertorié par un code précis. Lorsque la machine fonctionne, et en l'absence de défaut, ce voyant 71 indique 00.The control console includes a display panel 67 comprising a two-digit display lamp 68, which is displayed by means of knobs 69 and 70. This lamp is used to indicate to the machine the code corresponding to the dimensions of the drums to be found placed in the cells 2. The table 67 includes another indicator 71, also with two digits, which is used to indicate the state of the machine and the faults which may occur. When stopped, the indicator light 71 indicates for example, according to a code established in advance, 99, and each fault of such or such movement is listed by a precise code. When the machine is running, and in the absence of a fault, this light 71 indicates 00.

Le pupitre comporte en outre les boutons de commande suivants : marche et arrêt du compresseur, respectivement 72 et 73 ; marche et arrêt de la centrale hydraulique : respectivement 74 et 75 ; commutateur 76 pour la marche en automatique : a ou manuelle: b ; bouton 77 de mise en marche du cycle et bouton 78 de validation. A partir de ce moment, si le commutateur 76 est dans la position a (automatique), la machine se met en marche et le voyant 79 d'indication de marche automatique est allumé. Lorsque l'on appuie sur le bouton 77, le voyant 71 se met à 00.The console also has the following control buttons: compressor start and stop, respectively 72 and 73; on and off of the hydraulic power plant: 74 and 75 respectively; switch 76 for automatic operation: a or manual: b; button 77 for starting the cycle and button 78 for validation. From this moment, if the switch 76 is in position a (automatic), the machine starts and the indicator light 79 for automatic operation indication is on. When the button 77 is pressed, the indicator 71 goes to 00.

Si l'on veut arrêter momentanément le cycle, on appuie sur la touche 80 de suspension de cycle.If you want to stop the cycle temporarily, press the key 80 for cycle suspension.

Les autres boutons servent à la commande manuelle pour des opérations de réglage, entretien, vérifications etc. Il faut alors mettre le commutateur 76 dans la position manuelle : b. Il y a une touche 81 de retour au garage ; 82 de translation arrière ; 83 de descente pointes ; 84 d'écartement des bras supports et 85 de cisaillage des rubans d'acier.The other buttons are used for manual control for adjustment operations, maintenance, checks, etc. Then switch 76 must be set to the manual position: b. There is a 81 key back to the garage; 82 rear translation; 83 descent peaks; 84 for spacing the support arms and 85 for shearing the steel strips.

La machine comporte bien entendu un automate programmé pour toutes les fonctions et conditions de sécurité ; test de défauts ; présence de matériaux : planches, rubans d'acier etc..The machine naturally includes a PLC programmed for all safety functions and conditions; fault test; presence of materials: boards, steel ribbons, etc.
