Abstract

A preferred embodiment for a detechable gondola lift is disclosed in which carraiges on a closed circuit are detached from the circuit upon entering an end station and coupled to a semi-circular section before being recoupled onto the circuit upon exiting the end station. The semi-circular section has a drive wheel with a first drive mechanism on its periphery for driving the carriages over the semi-circular section. The first drive mechanism is located at regular intervals and driven at a predetermined first speed to impose a regular flow rate to the carriages leaving the semi-circular section and a regular distribution of carriages on the circuit. The semi-circular section also includes a second drive mechanism for imparting a slightly different speed to the carriages from that imposed by the drive wheel. One of the drive means has priority to impose a predetermined flow rate to the carriages leaving the semi-circular section. In another embodiment, the semi-circular section is divided into two straight rails and a circular rail on the drive wheel. In addition, the invention contemplates using two coaxial wheels: a drive wheel with pins and a support wheel. The pins may be fixed or retractable.

Description

L'invention est relative à une installation de transport à câble aérien à défilement continu en circuit fermé, ayant une voie montante et une voie descendante reliant deux stations d'extrémités, des charges, notamment des cabines, sièges ou analogues, étant supportées par des chariots à pince débrayable, susceptibles d'être accouplés au câble en ligne et d'être désaccouplés à l'entrée d'une station, les chariots de support des cabines circulant dans la station sur un circuit en demi-boucle reliant les voies descendante et montante avant d'être réaccouplés au câble à la sortie de la station.The invention relates to an overhead traveling cable transport installation in a closed circuit, having an uplink and a downlink connecting two end stations, loads, in particular cabins, seats or the like, being supported by trolleys with disengageable clamp, capable of being coupled to the in-line cable and of being uncoupled at the entrance to a station, the carriages supporting the cabs circulating in the station on a semi-loop circuit connecting the downlink channels and rising before being re-coupled to the cable at the station outlet.

La demande de brevet français FR-A-2 539 369 (& EP-A-0 114 129) fait connaître une installation du genre mentionné, qui utilise une chaîne de propulsion, s'étendant en boucle fermée le long du circuit de circulation des cabines ou sièges débrayés du câble dans les stations. La circulation sur les tronçons courbes du circuit est irrégulière et le dispositif d'entraînement en station est coûteux, bruyant et compliqué.French patent application FR-A-2 539 369 (& EP-A-0 114 129) discloses an installation of the kind mentioned, which uses a propulsion chain, extending in a closed loop along the circulation circuit of the cabins or seats disconnected from the cable in stations. The circulation on the curved sections of the circuit is irregular and the station training device is expensive, noisy and complicated.

La présente invention vise à simplifier le dispositif de circulation en station des cabines, tout en facilitant le passage des courbes et en conservant les avantages du système antérieur.The present invention aims to simplify the device for cabin station circulation, while facilitating the passage of curves and retaining the advantages of the prior system.

L'installation selon l'invention est caracterisée en ce que le circuit de circulation des cabines en station comporte un tronçon circulaire, notamment en demi-cercle, doté d'un dispositif d'entraînement positif des chariots comprenant une poulie à axe vertical, coïncidant avec l'axe dudit demi-cercle, la poulie étant entraînée en rotation et portant sur sa périphérie des moyens d'entraînement des chariots sur ledit tronçon en demi-cercle.The installation according to the invention is characterized in that the circulation circuit of the cabins in the station comprises a circular section, in particular in a semicircle, provided with a positive drive device for the carriages comprising a pulley with vertical axis, coinciding with the axis of said semicircle, the pulley being driven in rotation and carrying on its periphery means for driving the carriages on said semicircular section.

Dans la partie courbe du circuit l'entraînement est réalisé par une poulie à axe vertical, entraînée en rotation par un moteur ou par une prise de force sur le câble ou le mécanisme moteur de ce dernier. Le diamètre de cette poulie correspond de préférence à l'écartement de la ligne, pour permettre un raccordement par des rails rectilignes formant les quais d'embarquement et de débarquement. La propulsion sur les tronçons rectilignes est réalisée d'une manière classique, par gravité, chaîne, roues de friction et analogue.In the curved part of the circuit, the drive is carried out by a pulley with a vertical axis, driven in rotation by a motor or by a power take-off on the cable or the motor mechanism of the latter. The diameter of this pulley preferably corresponds to the spacing of the line, to allow connection by rectilinear rails forming the embarkation and disembarkation platforms. The propulsion on the straight sections is carried out in a conventional manner, by gravity, chain, friction wheels and the like.

L'entraînement par une poulie sur le tronçon courbe de renvoi est particulièrement approprié à la réalisation d'un dispositif cadenceur, du type décrit dans la demande de brevet précitée, qui maintient automatiquement l'espacement régulier des cabines pendant toute la durée de fonctionnement de l'installation. Selon un premier mode de réalisation, le dispositif d'entraînement du tronçon rectiligne, par exemple les roues de friction, est prolongé sur une partie du tronçon courbe, pour constituer un deuxième système d'entraînement, par exemple à vitesse légèrement inférieure ou supérieure à celle de la poulie. Selon la position de la cabine à l'entrée de cette partie du tronçon courbe, elle est propulsée par l'un ou l'autre des moyens d'entraînement pour rattraper un retard ou au contraire absorber une avance. Le fonctionnement d'un tel cadenceur est décrit dans la demande de brevet précitée à laquelle on se reportera pour de plus amples détails sur de tels cadenceurs.The drive by a pulley on the curved return section is particularly suitable for the production of a timing device, of the type described in the aforementioned patent application, which automatically maintains the regular spacing of the cabins throughout the operating time of the installation. According to a first embodiment, the device for driving the straight section, for example the friction wheels, is extended over part of the curved section, to constitute a second drive system, for example at a speed slightly lower or higher than that of the pulley. Depending on the position of the cabin at the entrance to this part of the curved section, it is propelled by one or the other of the drive means to catch up with a delay or, on the contrary, absorb an advance. The operation of such a timer is described in the aforementioned patent application to which reference will be made for further details on such timers.

Le tronçon courbe cadenceur peut comporter un entraînement lent par gravité ou à arrêt momentané de la cabine, la poulie d'entraînement rattrapant la cabine plus ou moins rapidement selon la position de cette dernière.The timed curved section can comprise a slow gravity drive or a momentary stop of the cabin, the drive pulley catching up with the cabin more or less quickly depending on the position of the latter.

Le deuxième moyen d'entraînement associé au tronçon cadenceur peut, selon un développement de l'invention, être une deuxième poulie coaxiale à la première et tournant à une vitesse légèrement différente. La propulsion par l'une des poulies est prioritaire en faisant usage, par exemple de taquets d'entraînement unidirectionnel sur l'une des poulies.The second drive means associated with the timing section may, according to a development of the invention, be a second pulley coaxial with the first and rotating at a slightly different speed. Propulsion by one of the pulleys has priority by making use, for example of one-way drive cleats on one of the pulleys.

L'installation peut être du type monocâble ou bicâble, les cabines ou sièges, débrayés du câble en station, circulant sur un rail, qui peut s'étendre le long de tout le parcours, notamment autour de la poulie d'entraînement ou sur des parties de ce parcours, notamment sur les parties rectilignes. Dans ce dernier cas la poulie d'entraînement est agencée pour supporter les cabines sur le tronçon courbe et la face supérieure de la poulie est conformée en rail circulaire, dans lequel s'engage le ou les galets des chariots de support des cabines, par exemple par une section de raccordement en pente. Tout autre mode de support ou de raccordement est d'ailleurs utilisable.The installation can be of the single-cable or two-cable type, the cabins or seats, disengaged from the cable in station, running on a rail, which can extend along the entire route, in particular around the drive pulley or on parts of this route, especially on the straight parts. In the latter case the drive pulley is arranged to support the cabins on the curved section and the upper face of the pulley is shaped as a circular rail, in which engages the roller or rollers of the cab support carriages, for example by a sloping connection section. Any other mode of support or connection can also be used.

Le rail peut être porté par une poulie de support, coaxiale à la poulie d'entraînement et les deux poulies peuvent être entraînées en rotation à des vitesses légèrement différentes pour réaliser le cadencement.The rail can be carried by a support pulley, coaxial with the drive pulley and the two pulleys can be rotated at slightly different speeds to achieve timing.

La fréquence de défilement des cabines est déterminée par la vitesse de rotation de la poulie cadenceuse et par l'écartement des moyens d'entraînement, en l'occurrence des taquets répartis sur la circonférence de la poulie. Les possibilités de variation de la vitesse de circulation des cabines sont limitées et pour multiplier le débit de l'installation, par exemple du simple au double, il suffit de multiplier le nombre de taquets actifs. Certains taquets, un sur deux ou toute autre proportion, sont du type effaçable. Le déplacement des taquets de la position active vers la position effacée ou inactive peut être commandé par tout moyen opérant, en particulier par une came déplaçable susceptible d'actionner un talon du taquet pour le relever en position effacée. Seuls les taquets munis d'un talon, en l'occurrence un taquet sur deux, sont ainsi déplacés en position inactive lors du défilement devant la came placée en position de commande. Des systèmes analogues ou équivalents sont utilisables.The frequency of movement of the cabins is determined by the speed of rotation of the clocking pulley and by the spacing of the drive means, in this case the tabs distributed over the circumference of the pulley. The possibilities for varying the speed of movement of the cabs are limited and to multiply the flow rate of the installation, for example from simple to double, it suffices to multiply the number of active cleats. Some cleats, one in two or any other proportion, are of the erasable type. The movement of the tabs from the active position to the erased or inactive position can be controlled by any operating means, in particular by a movable cam capable of actuating a heel of the cleat to raise it in the erased position. Only the cleats provided with a heel, in this case one in two cleats, are thus moved to the inactive position when scrolling past the cam placed in the control position. Similar or equivalent systems can be used.

Le chariot 22 porte des galets de roulement 32 et de positionnement 34 et une plaque 36 d'entraînement susceptible de coopérer avec des roues 38 d'entraînement à pneumatiques. Une telle pince est par exemple décrite dans la demande de brevet français FR-A-2 497 750 (& EP-A-0 056 919), à laquelle on se référera avantageusement.In the figures, an overhead cable 10 of a single-cable chairlift which could be a cable car or a similar single-cable or two-cable transporter, passes through an end station 12 on a return pulley 14 driven in rotation by a motor 16. The seats 18 are fixed by a hanger 20 to a carriage 22 carrying a clamp 24 for coupling to the cable 10. A spring 26 biases the clamp 24 in the cable clamping position, the opening being controlled by a lever 28 cooperating with a fixed ramp 30. The carriage 22 carries rollers 32 and positioning rollers 34 and a drive plate 36 capable of cooperating with wheels 38 for driving tires. Such pliers are for example described in French patent application FR-A-2 497 750 (& EP-A-0 056 919), to which reference will advantageously be made.

A l'entrée de la station 12 est disposé parallèlement au câble 10 un rail 40 de transfert sur lequel s'engagent les galets 32. Simultanément, le levier 28 de commande d'ouverture de la pince 24 aborde la rampe 30 pour ouvrir la pince 24 et désaccoupler le chariot 22 du cable 10. Un faible mouvement relatif du chariot 22 par rapport au câble 10 dégage ce dernier de la pince 24. Un train de roues 38 à pneumatiques, portées par une poutre 42 parallèle au rail 40, coopèrent avec la plaque 36 du chariot 22 pour entraîner ce dernier. Les roues 38 sont entraînées en rotation par tout moyen approprié (non représenté), les premières roues du train tournant à la vitesse du câble 10 pour synchroniser le déplacement du chariot 22 tandis que les roues 38 suivantes décélèrent le chariot 22 désaccouplé du câble 10 et roulant sur le rail 40. Le rail 40 s'étend en demi-boucle dans la station pour rejoindre l'autre brin du cable 10 constituant l'autre voie du télésiège en passant devant une zone d'embarquement 44 si la station 12 est une station d'embarquement. Il est clair que cette station peut être une station de débarquement ou comporter à la fois un quai de débarquement et un quai d'embarquement des passagers, notam- nent des skieurs.At the entrance to the station 12 is arranged parallel to the cable 10 a transfer rail 40 on which the rollers 32 engage. Simultaneously, the lever 28 for controlling the opening of the clamp 24 approaches the ramp 30 to open the clamp 24 and uncouple the carriage 22 from the cable 10. A slight relative movement of the carriage 22 relative to the cable 10 releases the latter from the clamp 24. A set of wheels 38 with tires, carried by a beam 42 parallel to the rail 40, cooperate with the plate 36 of the carriage 22 to drive the latter. The wheels 38 are driven in rotation by any appropriate means (not shown), the first wheels of the train rotating at the speed of the cable 10 to synchronize the movement of the carriage 22 while the following wheels 38 decelerate the carriage 22 uncoupled from the cable 10 and rolling on the rail 40. The rail 40 extends in a half-loop in the station to join the other strand of the cable 10 constituting the other path of the chairlift passing in front of a boarding area 44 if the station 12 is a boarding station. It is clear that this station can be a landing station or include both a landing quay and a passenger embarkation quay, in particular skiers.

Le circuit en demi-boucle, formé par le rail 40, comporte un tronçon 46 d'extrémité en demi-cercle, auquel se raccordent deux tronçons rectilignes 48, 50 alignés chacun avec l'une des voies, montante et descendante, de la ligne. Au tronçon 46 en demi-cercle est associée une poulie 52 à axe vertical 54 d'entraînement des chariots 22 sur ce tronçon. Le diamètre de la poulie 52 est légèrement inférieur à celui de la trajectoire en demi-cercle et des taquets 56 d'entraînement font saillie radialement de la poulie 52 pour coopérer avec le chariot 22 circulant sur le tronçon 46. La poulie 52 est entraînée en rotation par un moteur 57 ou par tout autre moyen approprié à la vitesse de circulation en station des sièges ou cabines, appelés par la suite cabines. Sur les tronçons rectilignes 48, 50 les chariots 22 sont propulsés par les roues 38 échelonnées le long de ces tronçons. Dans l'exemple de réalisation représenté à la figure 2, les chariots 22 sont propulsés positivement sur l'ensemble du parcours en station, par les roues 38 sur le tronçon 48, par la poulie 52 sur le tronçon courbe 46 et par les roues 38 sur le tronçon 50 de sortie. Les dernières roues 38 du circuit constituent un dispositif d'accélération des chariots 22 pour synchroniser les vitesses des chariots 22 et du câble 10 avant le réaccouple- ment par fermeture de la pince 24 sur le cable 10. L'entraînement par la poulie 52 est particulièrement souple et silencieux et il permet une simplification notable du système de circulation en station. Il est clair que ces avantages sont conservés en équipant les tronçons rectilignes 48, 50 d'autres systèmes de propulsion, à gravité, à entraînement forcé ou mixtes.The half-loop circuit, formed by the rail 40, comprises a semicircular end section 46, to which two rectilinear sections 48, 50 are connected, each aligned with one of the channels, up and down, of the line . Associated with the semicircular section 46 is a pulley 52 with a vertical axis 54 for driving the carriages 22 on this section. The diameter of the pulley 52 is slightly smaller than that of the semicircular path and the driving lugs 56 project radially from the pulley 52 to cooperate with the carriage 22 circulating on the section 46. The pulley 52 is driven in rotation by a motor 57 or by any other means suitable for the speed of movement in the station of the seats or cabins, hereinafter called cabins. On the straight sections 48, 50 the carriages 22 are propelled by the wheels 38 staggered along these sections. In the exemplary embodiment shown in FIG. 2, the carriages 22 are propelled positively over the entire station route, by the wheels 38 on the section 48, by the pulley 52 on the curved section 46 and by the wheels 38 on the outlet section 50. The last wheels 38 of the circuit constitute a device for accelerating the carriages 22 for synchronizing the speeds of the carriages 22 and of the cable 10 before re-coupling by closing the clamp 24 on the cable 10. The drive by the pulley 52 is particularly flexible and silent and it allows a significant simplification of the circulation system in the station. It is clear that these advantages are preserved by equipping the straight sections 48, 50 with other propulsion systems, gravity, forced or mixed drive.

Le passage des chariots 22 sur le tronçon 46 en demi-cercle peut être amélioré en interrompant, de la manière représentée aux fig. 5 et 6, le rail 40 le long de ce tronçon 46 et en ménageant sur la face supérieure de la poulie 52 un rail 58 circulaire périphérique qui se raccorde aux extrémités du rail 40. Dans le cas d'un rail 58 à profil en U, le raccordement est réalisé par une aiguille (non représentée) en pente qui introduit ou extrait les galets 32 du rail 58. D'autres moyens de raccordement, adaptés au profil des rails 40, 58 sont utilisables. Il est clair que le roulement des galets 32 sur le rail 58 courbe est nul ou très faible, ce qui facilite la circulation des chariots 22 sur le tronçon courbe 46.The passage of the carriages 22 on the semi-circular section 46 can be improved by interrupting, as shown in FIGS. 5 and 6, the rail 40 along this section 46 and providing on the upper face of the pulley 52 a peripheral circular rail 58 which is connected to the ends of the rail 40. In the case of a rail 58 with a U-shaped profile , the connection is made by a sloping needle (not shown) which introduces or extracts the rollers 32 from the rail 58. Other connection means, adapted to the profile of the rails 40, 58 can be used. It is clear that the rolling of the rollers 32 on the curved rail 58 is zero or very weak, which facilitates the movement of the carriages 22 on the curved section 46.

Sur les figures 5 et 6, des roues 60 de friction, analogues aux roues 38 des tronçons rectilignes 48. 50, sont disposées sur un secteur de la poulie 52, en l'occurrence, mais non obligatoirement, à l'entrée de cette dernière. La vitesse linéaire des roues 60 est légèrement inférieure à celle de la poulie 52 et l'ensemble est agencé de telle manière qu'une cabine décalée en avance est entraînée par les roues 60 sur le secteur d'entrée de la poulie 52 et rattrappée en fin de secteur par le taquet 56, tandis qu'une cabine en retard est prise en charge directement à l'entrée par le taquet 56, lui imposant une vitesse plus grande pour rattraper son retard. Une roue libre de l'entraînement par friction permet le déplacement à vitesse rapide. Les galets 32 du chariot 22 roulent sur le rail 58 lors d'un entraînement lent. Le principe de fonctionnement de tels cadenceurs est décrit dans la demande de brevet précitée dont certaines particularités sont applicables au présent système.In FIGS. 5 and 6, friction wheels 60, similar to the wheels 38 of the straight sections 48. 50, are arranged on a sector of the pulley 52, in this case, but not necessarily, at the entry of the latter . The linear speed of the wheels 60 is slightly lower than that of the pulley 52 and the assembly is arranged such that a cabin offset in advance is driven by the wheels 60 on the input sector of the pulley 52 and caught up at the end of the sector by the cleat 56, while a cabin late is taken care of directly at the entrance by the cleat 56, imposing a higher speed on it to catch up. A friction wheel freewheel allows movement at high speed. The rollers 32 of the carriage 22 roll on the rail 58 during a slow drive. The operating principle of such timers is described in the aforementioned patent application, certain features of which are applicable to the present system.

Les figures 7 et 8 illustrent un autre mode de mise en oeuvre de l'invention, faisant usage de deux poulies coaxiales, la poulie d'entraînement 52 à taquets 56 et une poulie de support 62, portant sur sa périphérie le rail 58, recevant les galets 32 du chariot 22. Dans un système non cadenceur les poulies 52, 62 tournent en synchronisme, un cadencement pouvant être réalisé en faisant tourner la poulie de support 62 à une vitesse inférieure pour imposer la vitesse lente de circulation. Lors du rattrapage du chariot 22 par les taquets 56, les galets 32 roulent sur le rail 58 de la poulie 62.Figures 7 and 8 illustrate another embodiment of the invention, making use of two coaxial pulleys, the drive pulley 52 with cleats 56 and a support pulley 62, carrying on its periphery the rail 58, receiving the rollers 32 of the carriage 22. In a non-timing system the pulleys 52, 62 rotate in synchronism, a timing can be achieved by rotating the support pulley 62 at a lower speed to impose the slow speed of circulation. When the carriage 22 is taken up by the tabs 56, the rollers 32 roll on the rail 58 of the pulley 62.

La propulsion sur les tronçons rectilignes 48, 50 peut être réalisée par tous moyens appropriés, notamment par gravité, les figures 9 et 10 montrant à titre d'exemple une installation ayant un entraînement par gravité sur le tronçon d'entrée 48 et un entraînement par roues de friction 38 sur le tronçon de sortie 50. Une partie du tronçon 48 peut comporter des roues de friction ou d'autres organes de propulsion, tandis que le tronçon 50 peut être partiellement à circulation par gravité. Le spécialiste peut concevoir facilement d'autres combinaisons opérantes. Sur les figures 9 et 10, le secteur cadenceur de la poulie 52 est disposé du côté de la sortie du tronçon 46 en demi-cercle. Un chariot 22 arrivant en avance ou en retard sur ce tronçon cadenceur, par rapport à la fréquence prédéterminée est automatiquement repositionné par la vitesse différentielle entre la poulie 52 et les roues 60 à friction.Propulsion on the straight sections 48, 50 can be achieved by any appropriate means, in particular by gravity, FIGS. 9 and 10 showing by way of example an installation having a drive by gravity on the inlet section 48 and a drive by friction wheels 38 on the outlet section 50. A part of the section 48 may include friction wheels or other propulsion members, while the section 50 may be partially circulated by gravity. The specialist can easily design other operating combinations. In FIGS. 9 and 10, the timing sector of the pulley 52 is arranged on the side of the outlet of the section 46 in a semicircle. A carriage 22 arriving early or late on this timing section, with respect to the predetermined frequency is automatically repositioned by the differential speed between the pulley 52 and the friction wheels 60.

La poulie d'entraînement 52 comporte des taquets fixes 56, en l'occurrence trois, représentés en trait épais et un nombre égal ou différent de taquets effaçables 64, représentés en détail aux fig. 11 et 12. Les taquets fixes 56 et effaçables 64 sont alternés, la proportion de taquets fixes et effaçables pouvant être différente. Chaque taquet effaçable 64 est monté à pivotement sur un axe 66 et porte un talon 68, susceptible de coopérer avec une came 70, s'étendant le long du tronçon cadenceur ou sur une partie de ce dernier. La came 70 est elle-même déplaçable ou rétractable en une position de non engagement des talons 68. Lorsque la came 70 est rétractée les taquets effaçables 64 restent en position active et se comportent comme des taquets fixes, la poulie cadenceuse 52 étant alors à six taquets. En position active de la came 70 les taquets effaçables 64 sont relevés pour ne pas coopérer avec les chariots 22 (fig. 11) et la poulie cadenceuse 52 comporte trois taquets actifs assurant une cadence de défilement des chariots réduite de moitié. Il est clair que le système de changement de cadence et tout système particulier décrit en référence à l'une des figures est applicable ou peut être combiné à d'autres systèmes selon l'invention, notamment illustrés par d'autres figures. La commande d'effacement des taquets 64 peut être différente et concerner un taquet sur trois ou une autre proportion.The drive pulley 52 has fixed lugs 56, in this case three, shown in thick lines and an equal or different number of erasable lugs 64, shown in detail in FIGS. 11 and 12. The fixed 56 and erasable 64 cleats are alternated, the proportion of fixed and erasable cleats being able to be different. Each erasable cleat 64 is pivotally mounted on an axis 66 and carries a heel 68, capable of cooperating with a cam 70, extending along the timing section or on a part of the latter. The cam 70 is itself movable or retractable in a position of non-engagement of the heels 68. When the cam 70 is retracted the erasable cleats 64 remain in the active position and behave like fixed cleats, the timing pulley 52 then being six cleats. In the active position of the cam 70, the erasable lugs 64 are raised so as not to cooperate with the carriages 22 (FIG. 11) and the timing pulley 52 comprises three active lugs ensuring a rate of movement of the carriages reduced by half. It is clear that the rate change system and any particular system described with reference to one of the figures is applicable or can be combined with other systems according to the invention, in particular illustrated by other figures. The command to erase the tabs 64 may be different and concern one in three cleats or another proportion.

Le fonctionnement du cadenceur à taquets effaçables 64 ressort des figures 9 et 10. A l'instant représenté à la figure 9, un premier chariot 22 propulsé par un taquet fixe 56 arrive à la sortie du tronçon 46 en demi-cercle, tandis qu'un autre chariot 22 en avance entre sur ce tronçon 46 et va être rattrapé par un des taquets effaçables 64 en position active d'entraînement. Un troisième chariot 22, intercalé entre les deux autres vient d'entrer sur le tronçon cadenceur, le taquet effaçable 64 correspondant venant d'être relevé en position inactive par la came 70. Ce troisième chariot 22 est propulsé à vitesse lente par les roues à friction 60. Un moment plus tard, illustré par la figure 10, le premier chariot 22 s'est engagé sur le tronçon rectiligne 50, tandis que le troisième chariot 22 va être rattrapé par le taquet fixe 56 et que le dernier chariot, propulsé par un taquet effaçable 64, s'approche du tronçon cadenceur où son taquet 64 sera pivoté en position d'effacement par la came 70. Il est évidemment possible d'effacer en permanence ou d'enlever les taquets effaçables 64, le seul inconvénient étant un arrêt temporaire à l'entrée du tronçon courbe de chariots trop en avance. Tout arrêt est évité en prévoyant beaucoup de taquets effaçables 64.The operation of the erasable cleat timer 64 is shown in FIGS. 9 and 10. At the instant shown in FIG. 9, a first carriage 22 propelled by a fixed cleat 56 arrives at the exit of the section 46 in a semicircle, while another carriage 22 in advance enters this section 46 and will be overtaken by one of the erasable tabs 64 in the active drive position. A third carriage 22, inserted between the two others has just entered the clocking section, the corresponding erasable cleat 64 having just been raised to the inactive position by the cam 70. This third carriage 22 is propelled at slow speed by the wheels with friction 60. A moment later, illustrated in FIG. 10, the first carriage 22 has engaged on the straight section 50, while the third carriage 22 will be caught up by the fixed cleat 56 and the last carriage, propelled by an erasable cleat 64, approaches the timing section where its cleat 64 will be pivoted in the erasing position by the cam 70. It is obviously possible to permanently erase or remove the erasable cleats 64, the only drawback being a temporary stop at the entrance to the curved section of carriages too early. Any downtime is avoided by providing a lot of erasable tabs 64.

Les figures 13 à 15 représentent un autre perfectionnement dans lequel le tronçon 46 en demi-cercle est équipé de deux poulies coaxiales d'entraînement, une poulie 52 équipée de taquets d'entraînement 64, dont certains sont éventuellement effaçables de la manière décrite ci-dessus par action d'une came 70 représentée en trait discontinu à la figure 14 et une deuxième poulie 72, portant des taquets 74 d'entraînement unidirectionnel. Les taquets 74 sont articulés sur un axe vertical 76 et coopèrent avec une butée 78 pour assurer un entraînement positif dans le sens de rotation trigonométrique et un effacement des taquets 74 en sens opposé. La deuxième poulie 72 assure l'entraînement à vitesse lente non prioritaire, tandis que la poulie 52, qui tourne à une vitesse plus grande, détermine la cadence de défilement des chariots 22, les taquets 74 ne s'opposant pas au passage d'un chariot 22 propulsé par un taquet 64 à vitesse supérieure. Le cadencement s'effectue sur toute la longueur du tronçon courbe 46 et en prévoyant un nombre important de taquets 74 les cabines ne sont pratiquement jamais à l'arrêt. Il est inutile de décrire en détail le fonctionnement de ce système qui ressort de l'exposé précédent.FIGS. 13 to 15 show another improvement in which the semicircular section 46 is equipped with two coaxial drive pulleys, a pulley 52 equipped with drive cleats 64, some of which can be erased as described above. above by the action of a cam 70 shown in broken lines in Figure 14 and a second pulley 72, carrying tabs 74 unidirectional drive. The tabs 74 are articulated on a vertical axis 76 and cooperate with a stop 78 to ensure a positive drive in the direction of trigonometric rotation and an erasure of the tabs 74 in the opposite direction. The second pulley 72 provides the slow priority drive, while the pulley 52, which rotates at a higher speed, determines the rate of travel of the carriages 22, the tabs 74 not opposing the passage of a carriage 22 powered by a cleat 64 at higher speed. The timing is performed over the entire length of the curved section 46 and by providing a large number of cleats 74 the cabs are almost never stopped. It is unnecessary to describe in detail the operation of this system which emerges from the preceding description.

L'invention n'est bien entendu nullement limitée aux modes de mise en oeuvre plus particulièrement décrits et elle s'étend à des systèmes cadenceurs opérant par freinage ou accélération des cabines.The invention is of course in no way limited to the more particularly described modes of implementation and it extends to timing systems operating by braking or accelerating the cabs.
