Abstract

Apparatus for introducing elongate objects (M) into a transfer corridor (4) from a feed corridor (10) along which the objects (M) are axially moved in sequence. The transfer corridor (4) has star wheels (3') driven rotationally in synchronism, each wheel (3') having at least one socket whose section corresponds to that of the object. A receiving wheel (1) receives the objects (M) at the outlet of the feed corridor (10), to which wheel the guide members (4) of the transfer corridor are extended. The receiving wheel (1) is rotated at regular intervals corresponding to the rhythm of succession of the objects. At least one intermediate wheel (2) is interposed between the receiving wheel (1) and a first transfer wheel (3) for the passage of the objects (M) from one wheel to the other. The intermediate wheel (2) is rotationally driven continuously and at variable speed between the angular velocity of the receiving wheel (1) and that of the transfer wheel (3).

Description

L'invention a pour objet un dispositif d'introduction d'objets allongés dans un couloir de transfert de ces objets l'un à c8té de l'autre selon une direction perpendiculairé à leur axe et s'applique plus spécialement à l'alimentation en munitiors des tourelles d'artillerie.The subject of the invention is a device for introducing elongated objects into a corridor for transferring these objects one beside the other in a direction perpendicular to their axis and applies more particularly to the supply of munitiors of artillery turrets.

Une tourelle d'artillerie se compose schématiquement d'un tube de canon monté sur un chassis oscillant autour de deux tourillons définissant un axe horizontal sur un appui tournant lui-même autour d'un axe vertical. Les munitions sont placées dans une soute disposée au-dessous de l'affût et doivent donc être conduites l'une après l'autre jusqu'au tube de canon. A cet effet, la soute est reliée à l'affût par un couloir d'alimentation dans lequel les muntions, introduites automatiquement ou manuellement, se déplacent l'une derrière l'autre suivant la direction de leurs axes. A la sortie du couloir d'alimentation, les munitions passent dans un couloir de transfert qui les amène jusqu'au tube et qui se compose donc de deux parties, un couloir fixe placé dans l'affût et un couloir mobile placé dans le chassis oscillant.An artillery turret consists schematically of a barrel tube mounted on a frame oscillating around two trunnions defining a horizontal axis on a rotating support itself around a vertical axis. The ammunition is placed in a hold located below the carriage and must therefore be led one after the other to the barrel tube. For this purpose, the hold is connected to the carriage by a feeding corridor in which the muntions, introduced automatically or manually, move one behind the other in the direction of their axes. At the exit of the feed corridor, the ammunition passes in a transfer corridor which brings them to the tube and which therefore consists of two parts, a fixed corridor placed in the carriage and a mobile corridor placed in the oscillating chassis .

Normalement, dans le couloir de transfert, les munitions se déplacent l'une à côté de l'autre selon une direction perpendiculaire à leur axe, cette disposition permettant en particulier de faire tourner les munitions progressivement de façon à les amener selon une direction parallèleau tube de canon pour faciliter leur introduction dans la culasse.Normally, in the transfer corridor, the ammunition moves one next to the other in a direction perpendicular to their axis, this arrangement in particular making it possible to rotate the ammunition gradually so as to bring it in a direction parallel to the tube barrel to facilitate their introduction into the breech.

Généralement, pour effectuer le déplacement des munitions parallèlement à leur axe, le couloir de transfert est muni d'une série de plateaux à alvéoles imbriqués et montés rotatifs autour d'axes perpendiculaires à celui du couloir, celui-ci étant limité par deux organes de guidage parallèles écartés d'une distance égale au diamètre des munitions.Generally, to carry out the movement of the ammunition parallel to their axis, the transfer corridor is provided with a series of nested cell trays and rotatably mounted around axes perpendicular to that of the corridor, the latter being limited by two organs of parallel guidance spaced a distance equal to the diameter of the ammunition.

Chacun des plateaux de transfert comporte au moins deux alvéoles de section correspondante à celle de l'objet, encadrées chacune par deux bras qui assurent respectivement la prise en charge de l'objet venant du plateau précédent et sa poussée vers le plateau suivant.Each of the transfer trays comprises at least two cells of section corresponding to that of the object, each framed by two arms which respectively take care of the object coming from the previous tray and its push towards the next tray.

Ainsi, en même temps que l'objet est poussé hors de l'alvéole, l'alvéole suivante vient prendre en charge l'objet venant du plateau précédent. Le plus souvent, les plateaux à alvéoles comportent quatre alvéoles séparées par quatre bras et ont ainsi la forme de croix de Malte.Thus, at the same time as the object is pushed out of the cell, the next cell comes to take care of the object coming from the previous tray. Most often, the cell plates have four cells separated by four arms and o n t and the shape of a Maltese cross.

Il existe donc une discontinuité entre le rythme de succession des objets dans le couloir d'alimentation et dans le couloir de transfert puisque, dans le couloir d'alimentation, les objets se déplacent l'un derrière l'autre. suivant la direction de leurs axes et arrivent donc à la sortie de façon dis- continue alors que dans le couloir de tranfert, grâce aux plateaux à alvéoles imbriqués, le déplacement des objets peut s'effectuer de façon continue.There is therefore a discontinuity between the rate of succession of objects in the supply corridor and in the transfer corridor since, in the feed corridor, the objects move one behind the other. along the direction of their axes and therefore arrive at the exit di s - continuously while in the transfer corridor, thanks to the trays with nested cells, the movement of objects can be carried out continuously.

L'invention apporte une solution à ce problème grâce à un dispositif permettant d'introduire de façon continue dans le couloir de transfert les munitions arrivant de façon discontinue à la sortie du couloir d'alimentation.The invention provides a solution to this problem by means of a device making it possible to continuously introduce into the transfer corridor the ammunition arriving discontinuously at the exit from the supply corridor.

Le dispositif d'introduction selon l'invention comprend un plateau de réception des objets à la sortie du couloir-d'alimentation, jusqu'auquel sont prolongés les organes de guidage du couloir de transfert, ce plateau comprenant au moins une alvéole susceptible de venir se centrer sur l'axe du couloir d'alimentation par rotation autour d'un axe perpendiculaire aux organes de guidage à intervalles réguliers correspondant au rythme de succession des objets à la sortie du couloir d'alimentation ; des moyens de commande déterminent périodiquement la rotation du plateau de réception d'un angle (A) correspondant au remplacement de l'alvéole par la suivante dans l'axe du couloir d'alimentation ; un plateau intermédiaire, également associé aux organes de guidage et muni d'alvéoles en nombre égal à celui des plateaux de transferts, est interposé entre le plateau dejéception et le premier plateau de transfert pour le passage des objets de l'un à l'autre dans les alvéoles par rotation autour d'un axe perpendiculaire aux organes de guidage ; la rotation du plateau intermédiaire est déterminée par des moyens d'entrainement en continu et à vitesse variable associées à des moyens de commande de variations progressive périodiques de la vitesse de rotation entre une vitesse angulaire égale à celle du plateau de réception et une vitesse angulaire égale à celle du plateau de transfert à chaque fraction de tour correspondant au passage d'une munition du plateau de réception au plateau de transfert.The introduction device according to the invention comprises a tray for receiving objects at the exit from the supply corridor, up to which the guiding members of the transfer corridor are extended, this tray comprising at least one cell capable of coming center on the axis of the feed corridor by rotation about an axis perpendicular to the guide members at regular intervals corresponding to the rhythm of succession of objects at the exit of the feed corridor; control means periodically determine the rotation of the receiving plate by an angle (A) corresponding to the replacement of the cell by the following in the axis of the feed corridor; an intermediate plate, also associated with the guide members and provided with cells in a number equal to that of the transfer plates, is interposed between the reception plate and the first transfer plate for the passage of objects from one to the other in the cells by rotation about an axis perpendicular to the guide members; the rotation of the intermediate plate is determined by continuous drive means and at variable speed associated with means for controlling periodic progressive variations in the speed of rotation between an angular speed equal to that of the receiving plate and an equal angular speed to that of the transfer plate at each fraction of a turn corresponding to the passage of an ammunition from the reception plate to the transfer plate.

Dans un mode de réalisation préférentiel, le moyen de commande périodique de la rotation dù plateau de réception est constitué par un organe d'indexage entrainé en rotation en continu-par le moyen de commande général, à une vitesse angulaire de un tour par cycle de remplacement d'un objet par le suivant et susceptible de s'engager pendant une fraction de tour sur une rampe associée à chaque alvéole du plateau de réception et formant une came de commande de la rotation du plateau à une vitesse angulaire progressivement croissante ou décroissante entre deux positions stoppées .séparées par l'angle (A) de remplacement de l'alvéole.In a preferred embodiment, the means for periodically controlling the rotation of the receiving plate consists of an indexing member driven in continuous rotation-by the general control means, at an angular speed of one revolution per cycle of replacement of an object by the next one and capable of engaging during a fraction of a turn on a ramp associated with each cell of the receiving platform and forming a cam for controlling the rotation of the platform at a progressively increasing or decreasing angular speed between two positions stopped .separated by the angle (A) of replacement of the cell.

De préférence, le dispositif comprend un plateau intermédiaire unique assurant la liaison entre le plateau de réception et le premier plateau de transfert et l'organe d'indexage détermine une vitesse angulaire de rotation du plateau de réception progressivement croissante jusqu'à une vitesse égale à celle des plateaux de transfert puis progressivement décroissante, les d moyens de commande des variations périodiques de la vitesse du plateau intermédiaire déterminant un ralentissement dudit plateau jusqu'à une vitesse égale à celle du plateau de réception puis une augmentation de sa vitesse en synchronisme avec le plateau de réception jusqu'à la vitesse des plateaux de tranfert pendant la rotation de l'ensemble nécessaire au passagedesobjets du plateau de réception au plateau intermédiaire et enfin le maintien du plateau de liaison en synchronisme avec le plateau de tranfert au moins pendant la rotation de l'angle nécessaire au passage de l'objet du plateau intermédiaire au premier plateau de transfert, la vitesse ralentissant de nouveau, au début du cycle suivant, jusqu'à la vitesse du plateau de réception.Preferably, the device comprises a single intermediate plate ensuring the connection between the receiving plate and the first plate of transfer and the indexing member determines an angular speed of rotation of the reception plate progressively increasing up to a speed equal to that of the transfer plates then progressively decreasing, the means d controlling the periodic variations of the speed of the intermediate plate determining a slowing down of said plate to a speed equal to that of the reception plate then an increase in its speed in synchronism with the reception plate up to the speed of the transfer plates during the rotation of the assembly necessary for the passage of objects from the receiving plate to the intermediate plate and finally maintaining the connection plate in synchronism with the transfer plate at least during the rotation of the angle necessary for the passage of the object from the intermediate plate to the first transfer plate, the speed slowing down by again, at the start of the next cycle, up to the speed of the receiving plate.

Dans un mode de réalisation particulier, le moyen d'entrainement en rotation du plateau intermédiaire est constitué par un différentiel dont un planétaire est entrainé en rotation par le moyen de commande générale, en synchronisme avec les plateaux de transfert, l'autre planétaire commandant la rotation du plateau intermédiaire,et le moyen de commande des variations de la vitesse du plateau intermédiaire est un bras de commande de l'orientation de l'arbre porte-satellites du diférentiel, dont l'extrémité coopère avec une came entrainée en rotation par le moyen de commande générale à une vitesse angulaire, de tour par cycle de remplacement d'un objet et dont le profil détermine, par l'intermédiaire du diférentiel et en fonction des rapports de transmission, la variation continue à chaque cycle de la vitesse du plateau intermédiaire entre la vitesse du plateau de réception et la vitesse des plateaux de transfert.In a particular embodiment, the means for driving the intermediate plate in rotation is constituted by a differential, one planetary of which is driven in rotation by the general control means, in synchronism with the transfer plates, the other planetary controlling the rotation of the intermediate plate, and the means for controlling the variations of the speed of the intermediate plate is an arm for controlling the orientation of the planet carrier shaft of the differential, the end of which cooperates with a cam driven in rotation by the general control means at an angular speed, one revolution per replacement cycle for an object and whose profile determines, via the differential and according to the transmission ratios, the continuous variation at each cycle of the speed of the plate intermediate between the speed of the receiving plate and the speed of the transfer plates.

Ainsi, grâce à l'utilisation d'un plateau intermédiaire à vitesse variable, il est possible de faire passer progressivement chaque munition à la vitesse du couloir de transfert et sans à-coups.Thus, thanks to the use of an intermediate plate with variable speed, it is possible to gradually pass each munition at the speed of the transfer lane and smoothly.

En effet, à la sortie du couloir d'alimentation, le plateau de réception est stoppé pendant le temps nécessaire à son chargement par la munition venant du couloir d'alimentation. Pour des raisons de sécurité, les munitions sont évidemment séparées par un intervalle qui correspond au temps nécessaire pour le remplacement de l'alvéole du plateau de réception par la suivante. Ce remplacement s'effectue lui-même à vitesse variable, le plateau de réception augmentant progressivement de vitesse jusqu'à tourner à une vitesse supérieure à celle des plateaux de transfert. Pendant ce temps, le plateau intermédiaire, entrainé en rotation en synchronisme avec le plateau de réception, à pu prendre en charge la muntion venant de celui-ci. Grâce à cette augmentation de vitesse, il a été possible de rattraper la position.du premier plateau de transfert qui est entrainé en rotation en continu..La vitesse du plateau de réception et du plateau intermédiaire est alors réduite, à la fin du mouvement de prise en charge par le plateau intermédiaire jusqu'à la vitesse des plateaux de transfert. A-partir de ce moment, le plateau de réception ralentit de nouveau jusqu'à se stopper dans la position de centrage de l'alvéole suivante sur l'axe du couloir d'alimentation et la plateau intermédiaire prend la vitesse du plateau de transfert pour pousser la munition vers celui-ci.In fact, at the exit from the feed corridor, the receiving tray is stopped for the time necessary for its loading by the ammunition coming from the feed corridor. For security reasons, the ammunition is obviously separated by an interval which corresponds to the time necessary for the replacement of the cell of the receiving plate by the following. This replacement is carried out itself at variable speed, the reception plate progressively increasing speed until turning at a speed higher than that of the transfer plates. During this time, the intermediate plate, driven in rotation in synchronism with the reception plate, was able to take charge of the muntion coming from the latter. Thanks to that increase in speed, it was possible to make up for the position of the first transfer plate which is driven in continuous rotation..The speed of the receiving plate and the intermediate plate is then reduced, at the end of the pick-up movement through the intermediate plate up to the speed of the transfer plates. From this moment, the receiving plate slows down again until it stops in the centering position of the next cell on the axis of the feed corridor and the intermediate plate takes the speed of the transfer plate to push the ammunition towards it.

On voit donc que, grâce aux variations périodiques de vitesse du plateau de réception et du plateau intermédiaire, il est possible d'introduire les munitions sans à-coups et en continu dans le couloir de transfert.It can therefore be seen that, thanks to the periodic variations in speed of the reception plate and of the intermediate plate, it is possible to introduce the ammunition smoothly and continuously into the transfer corridor.

Sur la figure 1, on a représenté schématiquement un couloir d'alimentation vertical 10 dans lesquels les munitions M se déplacent l'une à la suite de l'autre, suivant la direction de leurs axes, en étant séparées par un espace de sécurité (e).In FIG. 1, a vertical feed corridor 10 is shown schematically in which the ammunition M move one after the other, in the direction of their axes, being separated by a safety space ( e).

A la sortie du couloir d'alimentation 10, les munitions viennent se loger dans une paire de plateaux à alvéoles 1 et sont conduites dans le couloir de transfert 30 en passant par un couloir intermédiaire 20.At the exit from the supply corridor 10, the ammunition is housed in a pair of cell trays 1 and are led into the transfer corridor 30 via an intermediate corridor 20.

Le couloir de transfert est constitué, de façon très classique, d'une série de plateaux à alvéoles imbriqués 31 associés à des guides parallèles 4.The transfer corridor is very conventionally made up of a series of nested cell plates 31 associated with parallel guides 4.

Le couloir intermédiaire 20 comporte une seule paire de plateaux 2 interposés entre les plateaux de réception 1 et la première paire de plateaux 3 de la série de plateaux 3' du couloir de transfert 30.The intermediate passage 20 comprises a single pair of plates 2 interposed between the reception plates 1 and the first pair of plates 3 of the series of plates 3 ′ of the transfer passage 30.

De la même façon, les plateaux intermédiaires 20 sont associés à des guides 40 placés dans le prolongement dès guides 4 du couloir de transfert.In the same way, the intermediate plates 20 are associated with guides 40 placed in the extension from guides 4 of the transfer corridor.

De façon classique, comme on l'a représenté sur la figure 2, chaque plateau de transfert comme le plateau 3 comporte quatre alvéoles entre de poussée lesquelles sont interposés des bras/ . Les alvéoles ont une courbure qui correspond à celles des munitions-M et les plateaux ont donc, schématiquement, la forme d'une croix de Malte.Conventionally, as shown in FIG. 2, each transfer plate like the plate 3 comprises four cells between thrust which are interposed arms /. The cells have a curvature which corresponds to that of M-munitions and the plates therefore, schematically, have the shape of a Maltese cross.

Les organes de guidage, telles que les guides 40 du couloir intermér diaire et les guides 4 du couloir de transfert sont parallèles et écartés l'un de l'autre d'une distance égale au diamètre de la munition. Cette distance correspond évidemment à l'endroit où s'appuient les organes de guidage. Comme on le voit sur la figure 5, on utilise deux paires d'organes de guidage, l'une, 41, appelée guidage avant, prenant appui surle projectile alors que l'autre, 42 prend appui sur la douille. De la même façon, les diamètres des alvéoles des plateaux varient puisque l'un des plateau, appelé plateau avant, prend appui sur le projectile alors quel'autre plateau, appelé plateau arrière, prend appui sur la douille.The guide members, such as the guides 40 of the intermediate corridor and the guides 4 of the transfer corridor are parallel and spaced from one another by a distance equal to the diameter of the munition. This distance obviously corresponds to the place where the guide members are supported. As can be seen in FIG. 5, two pairs of guide members are used, one, 41, called front guide, bearing on the projectile while the other, 42 bears on the sleeve. In the same way, the diameters of the alveoli of the plates vary since one of the plates, called the front plate, bears on the projectile while the other plate, called the rear plate, bears on the sleeve.

Les deux plateaux avant et arrière sont ealés sur un arbre d'entraine- ment commun perpendiculaire aux organes de guidage et les arbns des plateaux 31 du couloir de transfert sont entrainés en synchronisme et dans le même sens par un moyen de commande générale non représenté. C'est pourquoi, tout ce qui concerne le plateau avant s'applique également au plateau arrière et chaque fois que, par la suite, on parlera d'un plateau, il s'agira évidemment de la paire de plateaux avant et arrière..The two front and rear plates are formed on a common drive shaft perpendicular to the guide members and the arbs of the plates 31 of the transfer passage are driven in synchronism and in the same direction by a general control means, not shown. This is why, everything concerning the front plate also applies to the rear plate and each time, subsequently, we will speak of a plate, it will obviously be the pair of front and rear plates.

Dans l'exemple représenté, deux munitions M1 et M2 (figure 1) sont séparées l'une de l'autre, dans le couloir de transfert 30 par deux intervalles libres représentés en pointillé sur la figure 2. Cette disposition, qui n'est pas indispensable, facilite le transfert sans à coups des munitions en laissant dans le couloir de transfert 30 un intervalle de deux emplacements qui correspond à la période avec laquelle les munitions M arrivent l'une après l'autre dans le plateau de réception 1. Il en résulte que chaque plateau 3 tourne de 3/4 de tour entre les moments où il prend en charge deux munitions successives c'est-à-dire à chaque cycle de remplacement d'une munition. Ainsi, dans ce mode de réalisation, le plateau doit comporter quatre alvéoles séparées angulairement de 1/4 de tour. C'est cette considération qui conduit à l'utilisation d'une forme en croix de Malte qui est la plus courante, mais on aurait pu, par exemple, utiliser des plateaux à une seule alvéole en laissant trois emplacements libres entre les munitions.In the example shown, two munitions M 1 and M 2 (Figure 1) are separated from each other, in the transfer corridor 30 by two free intervals shown in dotted lines in Figure 2. This arrangement, which n is not essential, facilitates the smooth transfer of ammunition by leaving in the transfer corridor 30 an interval of two locations which corresponds to the period with which the ammunition M arrive one after the other in the receiving tray 1 It follows that each plate 3 rotates 3/4 of a turn between the times when it takes charge of two successive munitions, that is to say at each cycle of replacement of an ammunition. Thus, in this embodiment, the tray must have four cells separated angularly by 1/4 of a turn. It is this consideration that leads to the use of a Maltese cross form which is the more common, but one could, for example, use trays with a single cell, leaving three free spaces between the ammunition.

Le plateau intermédiaire 2 doit comporter le même nombre d'alvéoles que le plateau 3. En revanche, le plateau de réception 1 pourrait ne comporter qu'une seule alvéole puisque l'on dispose d'un certain temps après la poussée de la munition hors de l'alvéole chargée pour faire tourner le plateau et ramener l'alvéole dans l'axe du couloir d'alimentation. Cependant, dans un but de simplification, on donne au plateau de réception 1 la même forme en croix de Malte à quatre alvéoles que les autres plateaux et, de la sorte, l'angle (A) dont il faut faire tourner le plateau 1 pour amener l'alvéole suivante dans l'axe 10 du couloir d'alimentation est de 90°.The intermediate plate 2 must comprise the same number of cells as the plate 3. On the other hand, the receiving plate 1 could comprise only one cell since there is a certain time after the thrust of the ammunition out of the loaded cell to rotate the tray and bring the cell in the axis of the feed corridor. However, for the sake of simplification, the receiving plate 1 is given the same Maltese cross shape with four cells as the other plates and, in this way, the angle (A) by which the plate 1 must be rotated to bringing the next cell in the axis 10 of the supply corridor is 90 °.

Les paires de plateaux 1, 2, 3 sont calées chacune,.respectivement sur des arbres de rotation 11, 21, 31 entrainés par des pignons, respectivement, 12, 22, 32 représentés à la partie inférieure de la figure 3 qui est une vue schématique générale du mécanisme d'entrainement.The pairs of plates 1, 2, 3 are each wedged, respectively on rotation shafts 11, 21, 31 driven by pinions, respectively, 12, 22, 32 shown in the lower part of FIG. 3 which is a view general diagram of the drive mechanism.

Le pignon 32 d'entrainement de l'arbre 31 du plateau 3 est commandé en synchronisme avec les pignons de commande de tous les plateaux 3' du couloir de transfert 30 par une chaine cinématique de commande générale symbolisée sur la figure 5 par un pignon 33 entrainé en rotation à une vitesse de 3/4 de tour par cycle et qui, sur la figure, entraine dans le même sens et à la même vitesse le pignon 32 de même diamètre par l'intermédiaire d'un pignon 34.The pinion 32 for driving the shaft 31 of the plate 3 is controlled in synchronism with the control pinions of all the plates 3 'of the transfer corridor 30 by a kinematic chain of general control symbolized in FIG. 5 by a pinion 33 driven in rotation at a speed of 3/4 of a turn per cycle and which, in the figure, drives in the same direction and at the same speed the pinion 32 of the same diameter by means of a pinion 34.

Le pignon 33 de commande générale commande également la rotation d'un indexeur 5 constitué d'un doigt 50 fixé à l'extrémité d'une manivelle calée sur un arbre 51 entrainé ..en rotation par le pignon 33 par l'intermédiaire d'un pignon 52, dont le nombre de dents est calculé en fonction de celui du pignon 33 pour que l'arbre 51 tourne à une vitesse de 1 tour par cycle. Il en résulte que le doigt d'indexage 50 fait un tour complet pendant le temps de remplacement d'une munition par la suivante.The pinion 33 of general control also controls the rotation of an indexer 5 consisting of a finger 50 fixed to the end of a crank wedged on a shaft 51 driven ..in rotation by the pinion 33 by means of a pinion 52, the number of teeth of which is calculated as a function of that of the pinion 33 so that the shaft 51 rotates at a speed of 1 revolution per cycle. As a result, the indexing finger 50 makes a full turn during the time for replacing one munition with the next.

Le doigt d'indexage 50 coopère avec un plateau d'indexage 53 sur lequel sont ménagées quatre rainures rectilignes 54 dirigées/vers du plateau 53 et écartées angulairement de 90°. La profondeur des rainures 54 correspond à la position occupée par le doigt d'indexage 50 lorsque la manivelle 5 est dirigée vers le centre du plateau 53. De la sorte, en tournant autour de l'arbre 51, le doigt d'indexage 50 qui s'engage dans une rainure 54, fait tourner le plateau 53 d'un angle de 90° à une vitesse progressivement croissante puis décroissante. La rainure 54 forme donc une came dont le profil détermine la variation de la vitesse et il est bien certain que si une forme rectiligne est plus simple, on pourrait imaginer bien d'autres formes donnant d'autres lois de variation de vitesse.The indexing finger 50 cooperates with an indexing plate 53 on which are formed four rectilinear grooves 54 directed / towards the plate 53 and spaced angularly by 90 °. The depth of the grooves 54 corresponds to the position occupied by the indexing finger 50 when the crank 5 is directed towards the center of the plate 53. In this way, by turning around the shaft 51, the indexing finger 50 which engages in a groove 54, rotates the plate 53 by an angle of 90 ° at a progressively increasing then decreasing speed. The groove 54 therefore forms a cam whose profile determines the variation in speed and it is quite certain that if a rectilinear shape is simpler, one could imagine many other shapes giving other speed variation laws.

Grâce à cette disposition, le plateau 53 tourne donc de 90° par cycle à une vitesse variable qui dépend de la forme de la came 54. Sur l'arbre du plateau 53 est calé un pignon 55 relié par une-chaine cinématique, par exemple un pignon 56, au pignon de commande 12 de l'arbre 11 du plateau de réception 1. Les pignons 12 et 55 ont le même diamètre et sont entrainés en rotation dans le même sens et à la même vitesse. Ainsi, l'indexeur 5 commande la rotation à 1/4/tourpar cycle et à vitesse variable du plateau de réception 1.Thanks to this arrangement, the plate 53 therefore rotates 90 ° per cycle at a variable speed which depends on the shape of the cam 54. On the shaft of the plate 53 is a pinion 55 connected by a kinematic chain, for example a pinion 56, to the control pinion 12 of the shaft 11 of the receiving plate 1. The pinions 12 and 55 have the same diameter and are rotated in the same direction and at the same speed. Thus, the indexer 5 controls the rotation at 1/4 / turn per cycle and at variable speed of the receiving plate 1.

La vitesse de rotation de l'indexeur 5 est réglée en fonction de la vitesse de déplacement des munitions M dans le couloir d'alimentation 10 de telle sorte que le plateau de réception 1 tourne de 1/4 de tour et par conséquent assure le remplacement d'une alvéole par la suivante en un temps (T) inférieur à celui que met la munition M pour parcourir l'espace (e) qui la sépare de la précédente. Ainsi, pendant ce temps (T), le plateau de réception pousse la munition M qu'il avait en charge dans le couloir intermédiaire 20 et remet l'alvéole suivante en attente dans l'axe du couloir d'alimentation 10.The speed of rotation of the indexer 5 is adjusted as a function of the speed of movement of the ammunition M in the feed corridor 10 so that the receiving plate 1 rotates 1/4 of a turn and therefore ensures replacement of a cell by the next one in a time (T) less than that which the munition M takes to traverse the space (e) which separates it from the previous one. Thus, during this time (T), the receiving plate pushes the ammunition M that it had in charge in the intermediate corridor 20 and puts the next cell back on hold in the axis of the supply corridor 10.

Ces mouvements des plateaux de transfert 3 et de réception 1 ont été représentés sur la figure 8 qui est un diagramme représentant en abscisse l'angle de rotation de l'arbre de commande d'indexage 51 tournant à un tour par cycle, et en ordonnée les angles de rotation des plateaux à alvéoles.These movements of the transfer and receiving plates 3 have been represented in FIG. 8 which is a diagram representing on the abscissa the angle of rotation of the indexing control shaft 51 rotating at one revolution per cycle, and on the ordinate the angles of rotation of the cell trays.

On a vu qu'à chaque cycle, le plateau de transfert 3 tourne de 3/4 de tour à vitesse constante. La courbe représentative du plateau de transfert est donc une droite (A G).We have seen that at each cycle, the transfer plate 3 rotates 3/4 of a turn at constant speed. The representative curve of the transfer plate is therefore a straight line (A G).

Pendant 2/4 de tour du plateau 3, le plateau récepteur 1 est stoppé et sa courbe représentative est donc constituée de deux segments de droites horizontaux (H C) et(F J) reliés par une courbe (C F). Les abscisses et les ordonnées des points extrêmes (C) et (F) sont séparés de 90° puisque le plateau 1 tourne de 1/4 de tour à une vitesse de 1 tour par cycle c'est-à-dire pendant 1/4 de cycle. La position des points (C) et (F) ainsi que la forme de la courbe (C F) sont déterminées par les caractéristiques de la came 54.During 2/4 of the turn of the plate 3, the receiving plate 1 is stopped and its representative curve is therefore made up of two segments of horizontal lines (H C) and (F J) connected by a curve (C F). The abscissas and ordinates of the extreme points (C) and (F) are separated by 90 ° since the plate 1 rotates 1/4 of a turn at a speed of 1 revolution per cycle, i.e. for 1/4 cycle. The position of the points (C) and (F) as well as the shape of the curve (C F) are determined by the characteristics of the cam 54.

Le plateau intermédiaire (2) doit se trouver pendant une partie du cycle à la vitesse du plateau récepteur (1) et pendant une autre partie du cy- cle à la vitesse du plateau de transfert (3), ces deux parties étant reliées par des périodes pendant lesquelles la vitesse du plateau 2 augmente ou diminue progressivement pour atteindre la valeur voulue. C'est pourquoi, sur le diagramme, on distinguera successivement :

  • Une partie (A B) de la droite (A G) pendant laquelle le plateau intermédiaire 2 se trouve à la vitesse du plateau de transfert 3 ; - une partie (B D) pendant laquelle la vitesse du plateau intermédiaire 2 diminue progressivement pour se mettre à la vitesse du plateau récepteur 1 et qui par conséquent est représentée par une courbe tangente en B à la droite (A G)-et en D à la courbe (M C F J) ;
  • - une partie (D E) pendant laquelle -es deux plateaux 1 et 2 tournent à la/vitesse et qui est donc constituée par un segment de la courbe représentative du plateau 1. C'est pendant ce temps que se produit le transfert de la munition du plateau récepteur 1 au plateau intermédiaire 2 et l'écartement en abscisse des points (D) et (E) doit donc être supérieur à l'angle dont tourne le plateau intermédiaire 2 entre le moment où il commence à prendre en charge la munition venant du plateau récepteur 1 et celui où la munition commence à être prise en charge par le plateau de transfert 3. Cet angle peut être par exemple de 60°.
The intermediate plate (2) is to be located during part of the cycle the velocity of the receiver plate (1) and during another part of the cyclic key e to the speed of the transfer plate (3), these two parts being connected by periods during which the speed of the plate 2 gradually increases or decreases to reach the desired value. This is why, on the diagram, we will successively distinguish:
  • A part (AB) of the straight line (AG) during which the intermediate plate 2 is at the speed of the transfer plate 3; - a part (BD) during which the speed of the intermediate plate 2 decreases progressively to get to the speed of the receiving plate 1 and which consequently is represented by a tangent curve in B to the right (AG) -and in D to the curve (MCFJ);
  • - a part (DE) during which the two plates 1 and 2 rotate at / speed and which is therefore constituted by a segment of the curve representative of the plate 1. It is during this time that the transfer of the ammunition occurs from the receiving plate 1 to the intermediate plate 2 and the spacing on the abscissa of the points (D) and (E) must therefore be greater than the angle which the intermediate plate 2 rotates between the moment when it begins to take charge of the ammunition coming of the receiving plate 1 and that where the ammunition begins to be supported by the transfer plate 3. This angle can be for example 60 °.

Au point (E) où, précisément, la munition commence à être prise en charge parle plateau de transfert 3, la vitesse du plateau intermédiaire 2 et par conséquent du plateau récepteur 1 doivent être égales à la vitesse du plateau de transfert 3. C'est pourquoi la forme de la came 54 est calculée de façon que la courbe (C F) représentative de la variation de vitesse du plateau de réception 1 soit tangente en (E) à la droite (A G) représentative de la rotation du plateau de transfert 3.At point (E) where, precisely, the ammunition begins to be taken care of by the transfer plate 3, the speed of the intermediate plate 2 and consequently of the receiving plate 1 must be equal to the speed of the transfer plate 3. C ' this is why the shape of the cam 54 is calculated so that the curve (CF) representative of the speed variation of the receiving plate 1 is tangent at (E) to the right (AG) representative of the rotation of the transfer plate 3 .

Après le point (E) la vitesse du plateau récepteur 1 diminue progressivement jusqu'à s'annuler en (F). En revanche, la vitesse du plateau intermédiaire 2 est égale à celle du plateau de transfert 3 etla courbe repré- sentative de la rotation du plateau 2 est donc représentée par le segment (E G) prolongé par le segment (A B) c'est-à-dire jusqu'au point où la vitesse du plateau intermédiaire recommence à décroître pour un nouveau cycle. C'est pendant ce temps que se produit le transfert de la munition du plateau intermédiaire 2 au plateau de transfert 3.After point (E) the speed of the receiving plate 1 gradually decreases until it is canceled out in (F). However, the speed of the intermediate plate 2 is equal to that of the transfer plate 3 andthe curve repre - sentative of the rotation of the plate 2 is therefore represented by the segment (EG) extended by the segment (AB) that is, - say to the point where the speed of the intermediate plate begins to decrease again for a new cycle. It is during this time that the ammunition is transferred from the intermediate plate 2 to the transfer plate 3.

Sur les figures, on a représenté à titre d'exemple un mécanisme permettant de faire varier la vitesse de rotation du plateau intermédiaire selon la loi désirée.In the figures, there is shown by way of example a mechanism making it possible to vary the speed of rotation of the intermediate plate according to the desired law.

Le pignon de commande 22 calé sur l'arbre 21 du plateau 2 est relié par un pignon 23 à un pignon 24 de même diamètre, de telle sorte que les pignons 22 et 24 tournent dans le même sens et à la même vitesse.The control pinion 22 wedged on the shaft 21 of the plate 2 is connected by a pinion 23 to a pinion 24 of the same diameter, so that the pinions 22 and 24 rotate in the same direction and at the same speed.

Le pi gnon 24 est solidaire en rotation d'un planétaire 61 d'un diférentiel 6 dont l'autre planétaire 62 est solidaire en rotation du pignon 34 (figure 5) entrainé en rotation à la même vitesse que le pignon 32 d'en- trainement des plateaux 3 et en sens inverse. De la sorte, si le diférentiel 6 n'apporte aucune correction, les pignons d'entrainement 22 du plateau intermédiaire 2 et 32 du plateau de transfert 3 sont entrainés dans le même sens et à la même vitesse par l'intermédiaire des planétaires du diférentiel 6.The pinion pin 24 is integral in rotation with a sun gear 61 with a differential 6 of which the other sun gear 62 is integral in rotation with the pinion 34 (FIG. 5) driven in rotation at the same speed as the pinion 32 of trailing of the plates 3 and in the opposite direction. In this way, if the differential 6 does not make any correction, the drive pinions 22 of the plate intermediate 2 and 32 of the transfer plate 3 are driven in the same direction and at the same speed via the planets of the differential 6.

Les satellites 63 du diférentiel 6 sont portés par un arbre central 64 qui est muni d'une manivelle 65 portant à son extrémité un galet 66. Ce galet roule sur une came 7 ménagée sur un disque calé sur l'arbre 51 de commande d'indexage.The satellites 63 of the differential 6 are carried by a central shaft 64 which is provided with a crank 65 carrying at its end a roller 66. This roller rolls on a cam 7 formed on a disc wedged on the shaft 51 for controlling indexing.

Sur la figure 7, on a représenté à titre d'exemple, à échelle agrandie, le profil que peut avoir la came 7 qui coopère avec le galet 6 et la manivelle 65 pour accélérer ou ralentir le plateau intermédiaire 2 par rapport au plateau de transfert 3.In Figure 7, there is shown by way of example, on an enlarged scale, the profile that may have the cam 7 which cooperates with the roller 6 and the crank 65 to accelerate or decelerate the intermediate plate 2 relative to the transfer plate 3.

Dès lors que les plateaux 2 et 3 tournent à la même vitesse pendant le temps nécessaire au passage de la munition de l'un à l'autre, on dispose de tout le reste du cycle pour faire varier la vitesse du plateau intermédiaire 2. Sur la figure 8 par exemple on voit que l'on a choisi de faire tourner le plateau intermédiaire 2 à la vitesse du plateau de transfert 3 pendant la moitié du cycle qui correspond aux segments (E G) et (A B).Pendant tout ce temps, aucune correction ne doit être apportée à la vitesse du planétaire 61 par rapport au planétaire 62 et par conséquent la partie correspondante 71 de la came 7, comprise entre les points E' et B' (figure 7) est un demi- cercle.As soon as the plates 2 and 3 rotate at the same speed for the time necessary for the passage of the ammunition from one to the other, we have all the rest of the cycle to vary the speed of the intermediate plate 2. On FIG. 8 for example we see that we have chosen to rotate the intermediate plate 2 at the speed of the transfer plate 3 during half of the cycle which corresponds to the segments (EG) and (AB). no correction should be made to the speed of the sun gear 61 relative to the sun gear 62 and therefore the corresponding part 71 of the cam 7, between the points E 'and B' (Figure 7) is a semicircle.

Sur la figure 8, on peut mesurer à chaque instant (t) du cycle le décalage angulaire(p)devant exister entre les plateaux 2 et 3 qui correspond à la différence des ordonnées des points (P1) de la droite (A G) représentative du mouvement du plateau 3 et (P2) de la courbe (A B D E G ) représentative du mouvement du plateau, qui correspondent à l'instant (t) du cycle. L'angle (10) correspond donc à la correction qui doit être apportée à chaque instant par la came 7 aux mouvements du plateau 2. Cette correction ext maximale au point (K) où la tangente à la courbe ( A B D E G ) est parallèle à la droite (A G). Le plateau 2 tourne à une vitesse inférieure à celle du plateau 3 entre les points ( B) et (K) et à une vitesse supérieure entre les points (K) et (E). Si l'on prend comme ordonnée en chaque point la correction angulaire (p) qui doit être apportée, on peut en déduire la courbe (L) représentative de la correction qui doit être donnée par la came. Comme on l'a indiqué cette correction est répartie entre les points (B') et (K1) de la came et le point(K1) de la courbe (L) correspond angulairement au sommet K' de la came pour lequel la correction est maximale. Le rapport entre les ordonnées (pl)de la courbe (1) et les distances (p') des points de la came au centre de rotation est calculé en tenant compte des rapports de vitessesdonnés par le diférentiel.In FIG. 8, it is possible to measure at each instant (t) of the cycle the angular offset (p) which must exist between the plates 2 and 3 which corresponds to the difference of the ordinates of the points (P1) of the line (AG) representative of the movement of the plate 3 and (P2) of the curve (ABDEG) representative of the movement of the plate, which correspond to the instant (t) of the cycle. The angle (10) therefore corresponds to the correction which must be made at all times by the cam 7 to the movements of the plate 2. This maximum ext correction at the point (K) where the tangent to the curve (ABDEG) is parallel to the right (AG). The plate 2 rotates at a speed lower than that of the plate 3 between the points (B) and (K) and at a higher speed between the points (K) and (E). If we take as an ordinate at each point the angular correction (p) which must be made, we can deduce the curve (L) representative of the correction which must be given by the cam. As indicated, this correction is distributed between the points (B ') and (K 1 ) of the cam and the point (K1) of the curve (L) angularly corresponds to the top K' of the cam for which the correction is maximum. The ratio between the ordinates (p l ) of the curve (1) and the distances (p ') from the points of the cam to the center of rotation is calculated by taking account of the ratios of speeds given by the differential.

En résumé, les mouvements du plateau intermédiaire 2 par rapport au plateau 3 sont les suivants :

  • Les deux plateaux tournent en synchronisme sur les segments (E G) et (A B). A partir du point (B), la vitesse du p ateau 2 diminue jusqu'à se trouver égale à celle du plateau 1 au point (D). Cette vitesse est d'ailleurs presque nulle puisqu'en ce point, le plateau de réception vient seulement de commencer à se mettre en rotation. La vitesse des deux plateaux 1 et 2 augmente rapidement jusqu'à se trouver égale au point (K) à celle du plateau 3. Elle continue à augmenter pour que le plateau 2 tourne de l'angle nécessaire pour rattraper la position angulaire du plateau 3 puis diminue de nouveau de telle sote qu'au point (E) les trois plateaux se trouvent à la même vitesse. Entre les.points (D) et (E), la munition a été transférée du plateau 1 au plateau 2. A partir du point e, la munition peut Stre transférée du plateau 2 au plateau 3, dont les arbres tournent à la même vitesse.
In summary, the movements of the intermediate plate 2 relative to the plate 3 are as follows:
  • The two plates rotate in synchronism on the segments (EG) and (AB). From point (B), the speed of deck 2 decreases until it is equal to that of platform 1 at point (D). This speed is also almost zero since at this point, the receiving plate has only just started to rotate. The speed of the two plates 1 and 2 increases rapidly until it is equal to point (K) to that of the plate 3. It continues to increase so that the plate 2 rotates by the angle necessary to catch up with the angular position of the plate 3 then decrease again so much that at point (E) the three plates are at the same speed. Between points (D) and (E), the ammunition has been transferred from plateau 1 to plateau 2. From point e, the ammunition can be transferred from plateau 2 to plateau 3, whose shafts rotate at the same speed .

On a ainsi défini les moyens permettant d'introduire dans un cycle continu de déplacement les munitions arrivant de façon discontinue à la sortie du couloir d'alimentation. Il est bien évident cependant que le mode de réalisation qui a été décrit n'a été donné qu'à titre d'exemple car on pourrait imaginer bien d'autres variantes permettant d'obtenir le même résultat par des moyens équivalents. En particulier, les variations de vitesse des plateaux qui sont commandées, dans l'exemple donné, par des moyens mécaniques, pourraient également être obtenues par des moyens hydrauliques ou électroniques.We have thus defined the means making it possible to introduce ammunition arriving discontinuously at the exit from the supply corridor into a continuous movement cycle. It is obvious, however, that the embodiment which has been described has been given only by way of example since one could imagine many other variants making it possible to obtain the same result by equivalent means. In particular, the speed variations of the plates which are controlled, in the example given, by mechanical means, could also be obtained by hydraulic or electronic means.

Enfin, si l'invention a été décrite dans le cas du transport de munitions, elle pourrait aussi être appliquée au transport d'autre objets chaque fois que l'on doit introduire dans un couloir de déplacement continu des objets arrivant de façon discontinue à son entrée.Finally, if the invention has been described in the case of the transport of ammunition, it could also be applied to the transport of other objects whenever it is necessary to introduce into a corridor of continuous movement of objects arriving discontinuously at its Entrance.
