Abstract

The overhead cable transport installation possesses at each of the stations a transfer section between a disembarking section and an embarking section. At a still linear starting section of each transfer section there are provided driven wheels and at the linear end or terminal section of each transfer section there are likewise provided driven wheels. The driven wheels at the starting section are driven at a stepped greater rotational speed in relation to wheels located at the disembarking section, so that vehicles of the overhead cable transport installation arriving in the transfer section can be accelerated by the driven wheels engaging at friction shoes of the vehicle. A chain conveyor extends between the driven wheels of the starting section of the transfer section along the latter and transports the vehicles at an increased velocity and with a correspondingly greater mutual spacing from one another through curved portions of the transfer section. The driven wheels at the terminal section, which are driven by the wheels of the embarking section at a stepped greater rotational speed, again decelerates each vehicle prior to it arriving at the embarking section. At the disembarking section and the embarking section the vehicles thus can be moved at a lesser velocity and at minimum spacing or pitch from one another without vehicles colliding at the curved sections of the transfer section. The number of vehicles located at any given time at the transfer section can be maintained small.

Description

Die Erfindung betrifft eine Seilförderanlage nach dem Oberbegriff von Anspruch 1.The invention relates to a cable conveyor system according to the preamble of claim 1.

Seilförderanlagen der vorerwähnten Art sind als Umlaufbahnen für hohe Förderleistung bekannt. Diese Förderleistung beruht neben der vergleichsweise hohen Seilgeschwindigkeit auf einer grossen Anzahl von Fahrzeugen, die sich in dauerndem Umlauf befinden.Cable conveyor systems of the aforementioned type are known as orbits for high conveying capacity. In addition to the comparatively high rope speed, this conveying capacity is based on a large number of vehicles that are in constant circulation.

Das Zeitintervall zwischen sich folgenden Fahrzeugen-auch Takt genannt-ist bei Förderanlagen dieser Art über die ganze Umlaufbahn konstant und bleibt demnach auch beim Durchfahren der Stationen unverändert. Hingegen ist die Fahrgeschwindigkeit der Fahrzeuge auf der Einsteigstrecke und auf der Aussteigestrecke gegenüber jener in mit dem Seil gekuppeltem Zustand notwendigerweise erheblich kleiner. Daraus folgt zwingend, dass bei gleichem Zeitintervall zwei sich unmittelbar folgende Fahrzeuge einander umso näher sind, je kleiner die Fahrgeschwindigkeit auf diesen Strecken gehalten werden muss. Dieser Annäherung der Fahrzeuge sind jedoch Grenzen gesetzt und zwar durch die Grundrissabmessungen der Fahrzeugkabine, sowie die kleinsten Bogenradius der Ueberführungsstrecke zwischen der Einsteig- und der Aussteigstrecke. Diese Dimensionen, die in der Regel gegeben sind, bestimmen den kleinsten geometrischen Abstand zwischen sich folgenden Fahrzeugen und damit bei einer gegebenen Fahrgeschwindigkeit auch das Zeitintervall der Anlage.In conveyor systems of this type, the time interval between the following vehicles - also called the cycle - is constant over the entire orbit and therefore remains unchanged even when passing through the stations. On the other hand, the driving speed of the vehicles on the boarding section and on the boarding section is necessarily considerably lower than that when the cable is coupled. It follows from this that, with the same time interval, two vehicles immediately following one another are all the closer, the lower the driving speed on these routes must be kept. This approach of the vehicles is limited, however, by the floor plan dimensions of the vehicle cabin and the smallest radius of curvature of the transfer route between the boarding and alighting routes. These dimensions, which are generally given, determine the smallest geometrical distance between vehicles following behind and thus, at a given driving speed, also the time interval of the system.

Mit dem Ziel, eine weitere Leistungssteigerung zu ermöglichen, hat man bei einigen der heute im Betrieb befindlichen Seilschwebebahnen versucht, eine kritische Annäherung der Fahrzeuge auf der Ueberführungsstrecke durch eine hohe Geschwindigkeit bei Ein- und Ausstieg zu vermeiden. Hohe Geschwindigkeiten in diesen Bereichen sind jedoch für die Benützer zumindest unbequem, wenn nicht in gewissen Verhältnissen sogar unfallgefährdend.With the aim of enabling a further increase in performance, attempts have been made in some of the cable railway systems in operation today to avoid a critical approach of the vehicles on the transfer route by a high speed when boarding and alighting. However, high speeds in these areas are at least uncomfortable for the users, if not in certain circumstances even dangerous.

Aufgabe der Erfindung ist es, eine Seilförderanlage zu schaffen, bei welcher bei gleichzeitiger Verbesserung der Wirtschaftlichkeit der Verlauf der Ueberführungsstrecke auf den kleinsten geometrischen Abstand der Kabinen keinen Einfluss hat und demgemäss die Fahrgeschwindigkeit bei Ein- und Ausstieg klein und für die Benützer angenehm gehalten werden kann.The object of the invention is to provide a cable conveyor system in which, while at the same time improving the economy of the course of the transfer route, has no influence on the smallest geometric distance between the cabins and accordingly the driving speed when entering and exiting can be kept small and pleasant for the user .

Die Lösung der erfindungsgemässen Aufgabe gelingt mit den Merkmalen nach dem Kennzeichen von Anspruch 1.The object according to the invention is achieved with the features according to the characterizing part of claim 1.

Durch die Anordnung der Beschleunigungsmittel am Beginn der Ueberführungsstrecke und vor dem Bogen bzw. der Krümmung derselben gelingt es, sich folgende Fahrzeuge mindestens soweit voneinander zu distanzieren, dass die Fahrzeugkabinen auch im Bogen einen ausreichenden Abstand aufweisen.By arranging the acceleration means at the beginning of the transfer route and in front of the curve or the curvature thereof, it is possible to distance the following vehicles from one another at least to such an extent that the vehicle cabins are also sufficiently far apart in the curve.

Ein unerwarteter Vorteil der erfindungsgemässen Lösung liegt darin, dass bei gegebenen baulichen Verhältnissen der Anlage sich eine kleinere Zahl von Fahrzeugen im Umlauf befindet, um einen gegebenen Takt (Zeitintervall) einzuhalten. Die Ueberführungsstrecke wird infolge der höheren mittleren Fahrgeschwindigkeit in kürzerer Zeit durchfahren. Da die Ueberführungsstrecke den Totbereich der Anlage bildet, ergibt sich aus der Verringerung der Fahrzeugzahl eine Verbesserung der Wirtschaftlichkeit. Dabei ist andererseits der konstruktive Aufwand für die erfindungsgemässe Lösung gering.An unexpected advantage of the solution according to the invention is that, given the structural conditions of the system, a smaller number of vehicles are in circulation in order to keep to a given cycle (time interval). The transfer route is traversed in a shorter time due to the higher average driving speed. Since the transfer line forms the dead area of the system, the reduction in the number of vehicles results in an improvement in economy. On the other hand, the design effort for the solution according to the invention is low.

Da die erfindungsgemässe Lösung kleine Fahrgeschwindigkeiten auf der Einsteig- und der Aussteigstrecke zulässt, können diese Strecken ohne Nachteil für die Benützer kurz ausgelegt werden. Diese Tatsache lässt in der Regel auch kürzere Stationsgebäude zu, was sich nicht nur auf die Baukosten günstig auswirkt, sondern auch für die Auslegung vorteilhaft sein kann.Since the solution according to the invention allows low driving speeds on the boarding and alighting routes, these routes can be designed short without disadvantage for the users. As a rule, this fact also permits shorter station buildings, which not only has a favorable effect on the construction costs, but can also be advantageous for the design.

Ein weiterer Vorteil der erfindungsgemässen Lösung ergibt sich aus dem durch die höhere Fahrgeschwindigkeit gewonnenen geometrischen Abstand zwischen den Fahrzeugen auf der Ueberführungsstrecke in dem Sinn, das eine in dieser Strecke angeordnete Weiche auch im normalen Betrieb zum Ein- oder Ausschleusen eines Fahrzeuges betätigt werden kann. Diese kann für den Transport von invaliden Benützern oder den Materialtransport von Bedeutung sein.A further advantage of the solution according to the invention results from the geometric distance between the vehicles on the transfer route, which distance is obtained by the higher driving speed, in the sense that a switch arranged in this route can also be operated in normal operation to introduce or remove a vehicle. This can be important for the transport of disabled users or the transport of materials.

Die erfindungsgemässe Lösung lässt sich auch in einer Ueberführungsstrecke anwenden, die zwei Sektionen einer Anlage miteinander verbindet.The solution according to the invention can also be used in a transfer line which connects two sections of a plant to one another.

Vorzugsweise sind die Beschleunigungsmittel und die Verzögerungsmittel durch Räder gebildet, die mit ensprechenden Drehzahlen angetrieben werden und mit Reibschuhen zusammenwirken, welche an den Fahrzeugen angebracht sind. Um den Antrieb der Räder mit unterschiedlichen Drehzahlen zu ermöglichen, sind diese in vorteilhafter Ausgestaltung durch endlose Uebertragungselemente, z.B. durch Keilriemen, die über Riemenscheiben mit unterschiedlichen Durchmessern geführt sind, untereinander verbunden. Der Antrieb der Räder ist vorteilhafterweise vom Antrieb der Seilscheibe angeleitet.The acceleration means and the deceleration means are preferably formed by wheels which are driven at corresponding speeds and interact with friction shoes which are attached to the vehicles. In order to enable the wheels to be driven at different speeds, these are advantageously configured by endless transmission elements, e.g. connected to each other by V-belts, which are guided by pulleys with different diameters. The drive of the wheels is advantageously guided by the drive of the rope sheave.

Die mit konstanter Geschwindigkeit fördernden Mittel der Ueberführungsstrecke sind zweckmässig als an sich bekannte Kettenförderer ausgebildet, die die Fahrzeuge von den Beschleunigungsmitteln mit der entsprechend erhöhten Geschwindigkeit übernehmen, durch den Bogen der Ueberführungsstrecke bewegen und schliesslich den Verzögerungsmitteln übergeben.The means of the transfer line conveying at constant speed are expediently designed as chain conveyors known per se, which take over the vehicles from the accelerating means at the correspondingly increased speed, move them through the arc of the transfer line and finally transfer them to the deceleration means.

Nachfolgend ist die erfindungsgemässe Seilförderanlage anhand eines Ausführungsbeispieles und unter Bezugnahme auf die Zeichnung näher erläutert. In der Zeichnung zeigen:

  • Fig. 1 eine Station einer Einseilumlaufbahn schematisch im Grundriss;
  • Fig. 2 einen Ausschnitt aus Fig. 1 im Aufriss.
The cable conveyor system according to the invention is explained in more detail below using an exemplary embodiment and with reference to the drawing. The drawing shows:
  • Figure 1 shows a station of a single cable orbit schematically in plan.
  • Fig. 2 shows a detail of Fig. 1 in elevation.

Mit 1 ist in den Figuren 1 und 2 eine Fahrschiene bezeichnet, die in der Station eine U-förmige Bahn für Fahrzeuge 2 bildet. Ueber die Seilscheibe 3 verläuft ein mit 4 bezeichnetes Trag-und Zugseil. Die Fahrschiene 1 übernimmt die Fahrzeuge 2 über Fahrwerke 2a (Fig. 2) derselben beim Einlaufen in die Station, sobald diese vom Seil 4 abgekuppelt sind.1 in FIGS. 1 and 2 denotes a travel rail which forms a U-shaped path for vehicles 2 in the station. A support and traction cable, designated 4, runs over the pulley 3. The running rail 1 takes over the vehicles 2 via running gear 2a (FIG. 2) of the same when entering the station as soon as they are uncoupled from the rope 4.

Mit den Pfeilen 5 ist die Fahrrichtung der Fahrzeuge 2 angedeutet. Die Fahrschiene 1 verläuft in Fahrrichtung, ausgehend von einer Verzögerungsstrecke 6, über eine Aussteigstrecke 7, eine Ueberführungsstrecke 8, eine Einsteigstrecke 9 sowie eine Beschleunigungsstrecke 10. Entlang der Verzögerungsstrecke 6 und der Aussteigstrecke 7 einerseits und der Einsteigstrecke 9 sowie der Beschleunigungsstrecke 10 andererseits verlaufen Radsätze 11 bzw. 12, die oberhalb der Fahrschiene 1 angeordnet sind.Arrows 5 indicate the direction of travel of vehicles 2. The running rail 1 runs in the direction of travel, starting from a deceleration section 6, via a disembarkation section 7, a transfer section 8, an embarkation section 9 and an acceleration section 10 11 and 12, respectively, which are arranged above the running rail 1.

Diese Radsätze 11 und 12 können beispielsweise in derjenigen Art ausgestaltet und angetrieben sein, wie dies in der schweizerischen Patentanmeldung 02 468/86-8 beschrieben und dargestellt ist.These wheel sets 11 and 12 can, for example, be designed and driven in the manner described and illustrated in the Swiss patent application 02 468 / 86-8.

Während die Räder beider Radsätze 11, 12, welche im Bereich der Aussteigstrecke 7 bzw. der Einsteigstrecke 9 angeordnet sind, mit unter sich gleicher Drahzahl angetrieben werden, weisen jene Räder, die in den Bereichen der Verzögerungsstrecke 6, bzw. der Beschleunigungsstrecke 10 vorgesehen sind, untereinander unterschiedliche Drehzahlen auf. Diese Drehzahlen sind auf der Verzögerungsstrecke 6 in Fahrrichtung abnehmend und auf der Beschleunigungsstrecke 10 in Fahrrichtung zunehmend. Die Räder der Radsätze wirken als Reibräder an Reibschuhen 2b (Fig. 2) der Fahrzeuge 2 bzw. der Fahrwerke 2a derselben. Dementsprechend verzögern bzw. beschleunigen die Räder der entsprechenden Strecken die Fahrzeuge nach der Uebernahme vom Seil 4 bzw. vor der Uebergabe an dieses; die Räder der Verzögerungsstrecke wirken als Bremsmittel, während jene der Beschleunigungsstrecke als Antriebsmittel dienen.While the wheels of both wheel sets 11, 12, which are arranged in the area of the alighting section 7 and the boarding section 9, are driven with the same number of wires among themselves, those wheels which are provided in the areas of the deceleration section 6 and the acceleration section 10 respectively , different speeds among themselves. These speeds are decreasing on the deceleration route 6 in the direction of travel and increasing on the acceleration route 10 in the direction of travel. The wheels of the wheel sets act as friction wheels on friction shoes 2b (FIG. 2) of the vehicles 2 or the undercarriage 2a thereof. Accordingly, the wheels of the corresponding routes decelerate or accelerate the vehicles after the takeover of the rope 4 or before the transfer to it; the wheels of the deceleration section act as braking means, while those of the acceleration section serve as driving means.

Mit 13 ist allgemein ein an sich bekannter Kettenförderer bezeichnet, der an der Ueberführungsstrecke 8 unterhalb der Fahrschiene 1 angeordnet ist und ein Antriebsrad 14 umfasst. Der Kettenförderer 13 ist mit Mitnehmern 15 versehen, die an den je eine Kabine 2d tragenden Gehängen 2c der Fahrzeuge 2 angreifen und diese letzteren mit einer vorgegebenen Fahrgeschwindigkeit fördern.13 generally denotes a chain conveyor known per se, which is arranged on the transfer line 8 below the travel rail 1 and comprises a drive wheel 14. The chain conveyor 13 is provided with drivers 15, which engage on the hangers 2c of the vehicles 2, each carrying a cabin 2d, and convey the latter at a predetermined driving speed.

Erfindungsgemäss ist nun die vorgegebene Fahrgeschwindigkeit im Bereich des Kettenförderers 13 nicht gleich der Fahrgeschwindigkeit der Fahrzeuge 2 auf der Aussteigstrecke 7 bzw. der Einsteigstrecke 9, sondern sie ist gegenüber dieser erheblich grösser. Für die höhere Geschwindigkeit sind Beschleunigungsmittel 16 verantwortlich, die auf einem geraden Anfangsabschnitt 17 der Ueberführungsstrecke 8 vor deren als Viertelkreisbogen 8a und 8b ausgebildeten Krümmungen wirksam sind. Auf einem geraden Endabschnitt 18 dieser Strecke 8 sind andererseits Verzögerungsmittel 19 wirksam, welche die Kabinen von der vorgegebenen Geschwindigkeit des Kettenförderers 13 auf die Fahrgeschwindigkeit der Einsteigstrecke 9 abbremsen.According to the invention, the predetermined driving speed in the area of the chain conveyor 13 is not the same as the driving speed of the vehicles 2 on the alighting route 7 or the alighting route 9, but is considerably greater than this. Accelerating means 16 are responsible for the higher speed and act on a straight starting section 17 of the transfer path 8 in front of the curvatures formed as quarter arcs 8a and 8b. On a straight end section 18 of this section 8, on the other hand, deceleration means 19 are effective, which brake the cabs from the predetermined speed of the chain conveyor 13 to the driving speed of the boarding section 9.

Die Beschleunigungsmittel 16 und die Verzögerungsmittel 19 sind im dargestellten Ausführungsbeispiel als Räder 20 und 21 bzw. 22 und 23 ausgebildet, die je eine Verlängerung der Radsätze 11 bzw. 12 bilden. Der Antrieb der Räder 20, 21 bzw. 22, 23 erfolgt von den benachbarten Rädern der Radsätze 11 und 12 über nicht dargestellte Keilriemen und Riemenscheiben. Durch die Durchmesserabstufung der Riemenscheiben der beteiligten Räder erhalten diese abgestuft höhere Drehzahlen, wobei das Rad 21 eine höhere Drehzahl als das Rad 20 und das Rad 23 eine kleinere Drehzahl als das Rad 22 hat.The acceleration means 16 and the deceleration means 19 are designed in the exemplary embodiment shown as wheels 20 and 21 or 22 and 23, each of which forms an extension of the wheel sets 11 and 12, respectively. The wheels 20, 21 and 22, 23 are driven by the adjacent wheels of the wheel sets 11 and 12 via V-belts and pulleys, not shown. Due to the diameter gradation of the pulleys of the wheels involved, they receive stepped higher speeds, the wheel 21 having a higher speed than the wheel 20 and the wheel 23 having a lower speed than the wheel 22.

Aus Fig. 1 ist weiter ersichtlich, dass sowohl der Antrieb der Radsätze 11 und 12 wie auch des Kettenförderers 13 von der Seilscheibe 3 abgeleitet ist. Hierzu ist die Seilscheibe 3 mit einem Verzweigungsgetriebe 24 gekuppelt, das über Wellen 25 und 26 mit den Getrieben 27 bzw. 28 in Antriebsverbindung steht. Von dem ebenfalls als Verzweigungsgetriebe ausgebildeten Getriebe 27 werden die Radsätze 11 und 12 über Wellen 29 bzw. 30 angetrieben.From Fig. 1 it can also be seen that both the drive of the wheel sets 11 and 12 and the chain conveyor 13 is derived from the pulley 3. For this purpose, the sheave 3 is coupled to a branching gear 24, which is in drive connection via shafts 25 and 26 with the gears 27 and 28, respectively. The gear sets 11 and 12 are driven by shafts 29 and 30, respectively, from the transmission 27, which is also designed as a branching gear.

Schliesslich ist das Getriebe 28 über eine Welle 31 mit dem z.B. als Kettenrad ausgebildeten Antriebsrad 14 des Kettenförderers 13 verbunden.Finally, the gear 28 is connected via a shaft 31 to the e.g. Drive wheel 14 of chain conveyor 13 designed as a chain wheel.

Die Wirkungsweise der erfindungsgemässen Seilförderanlage ist in Fig. 1 durch die Positionen der Kabinen 2 angedeutet. Die zu einem bestimmten Zeitpunkt in der Station befindlichen Fahrzeuge 2 sind zur Unterscheidung ihrer momentanen Positionen mit A, B, C usw. bezeichnet.The mode of operation of the cable conveyor system according to the invention is indicated in FIG. 1 by the positions of the cabins 2. The vehicles 2 in the station at a specific point in time are designated by A, B, C, etc. to distinguish their current positions.

Auf der Aussteigstrecke 7 befinden sich die mit A, B und C bezeichneten Fahrzeuge 2. Dabei ist das Fahrzeug A in einem angenommen soeben verstrichenen Takt oder Zeitintervall in die Strecke 7 eingefahren. Auf der Verzögerungsstrecke 6 war dieses Fahrzeug von der Seilgeschwindigkeit von beispielsweise 4 m/sec auf eine Fahrgeschwindigkeit abgebremst worden, die ein müheloses Aussteigen der Passagiere erlaubt, z.B. 0,2 m/sec. Als Folge der Abnahme der Fahrgeschwindigkeit bei gleichbleibendem Zeitintervall haben sich die Fahrzeuge A, B und C einander soweit genähert, dass deren Abstand wenig grösser ist als die Kabinenlänge.Vehicles 2, A, B and C are located on exit route 7. Vehicle A has entered route 7 at an interval or interval that has just passed. On the deceleration route 6, this vehicle had been braked from the rope speed of, for example, 4 m / sec to a driving speed which allowed the passengers to get out easily, e.g. 0.2 m / sec. As a result of the decrease in driving speed with the same time interval, vehicles A, B and C have moved so far that their distance is only slightly greater than the cabin length.

Während das Fahrzeug C sich kurz vor dem mit den Beschleunigungsmitteln 16 besetzten Abschnitt 17 befindet, hat das Fahrzeug D diesen Abschnitt schon überfahren und ist in den Wirkungsbreich des Kettenförderers 13 gelangt. Unter der Einwirkung der Beschleunigungsmittel 16 hat das Fahrzeug D eine höhere Fahrgeschwindigkeit, z.B. 0,6 m/sec angenommen, die der Umlaufgeschwindigkeit des Kettenförderes entspricht. Das Fahrzeug D hat dementsprechend vom Fahrzeug C einen vergrösserten Abstand gewonnen. Der Kettenförderer 13 transportiert das Fahrzeug D nun mit dieser höheren Fahrgeschwindigkeit weiter.While the vehicle C is shortly before the section 17 occupied by the acceleration means 16, the vehicle D has already passed this section and has come into the range of action of the chain conveyor 13. Under the action of the acceleration means 16, the vehicle D has a higher driving speed, e.g. Assumed 0.6 m / sec, which corresponds to the rotational speed of the chain conveyor. The vehicle D has accordingly gained an increased distance from the vehicle C. The chain conveyor 13 now transports the vehicle D at this higher driving speed.

Es ist ersichtlich, dass das Fahrzeug D beim Durchfahren der Bogen 8a und 8b der Ueberführungsstrecke 8 weder durch das Fahrzeug C noch durch das Fahrzeug E behindert werden kann.It can be seen that the vehicle D cannot be hindered by either the vehicle C or the vehicle E when passing through the bends 8a and 8b of the transfer path 8.

Das Fahrzeug E wurde während des soeben verstrichenen Zeitintervalles aus derjenigen Position, die das Fahrzeug D nun einnimmt, vermittels des Kettenförderers 13 mit konstanter Geschwindigkeit in die dargestellte Position transportiert.The vehicle E was conveyed from the position which the vehicle D now occupies during the time interval which has just passed of the chain conveyor 13 transported to the position shown at a constant speed.

Während des gleichen Zeitintervalles hat das Fahrzeug F den Abschnitt 18 durchfahren und ist dabei auf die Einsteiggeschwindigkeit abgebremst worden. Mit dieser Geschwindigkeit, die als gleich hoch wie jene auf der Strecke 7 dargestellt ist, bewegt sich aus das Fahrzeug G auf der Einsteigestrecke 9. Das Fahrzeug H schliesslich hat die Einsteigstrecke 9 verlassen und wird nun auf der Strecke 10 beschleunigt.During the same time interval, vehicle F has passed section 18 and has been braked to the boarding speed. At this speed, which is shown as being the same as that on route 7, vehicle G is moving on boarding section 9. Vehicle H has finally left boarding section 9 and is now accelerating on section 10.

Es ist anzumerken, dass die Fahrgeschwindigkeit der Fahrzeuge auf den Strecken 7 und 9 nicht identisch sein muss. Die Erfindung gestattet vielmehr, für diese Strecken voneinander abweichende Fahrgeschwindigkeiten vorzusehen, wenn dies zweckmässig ist.It should be noted that the speed of the vehicles on routes 7 and 9 does not have to be identical. Rather, the invention makes it possible to provide driving speeds which differ from one another for these routes if this is expedient.

Nachzutragen ist, dass die als Reibräder wirkenden Räder 20, 21, 22 und 23 vorzugsweise als Pneuräder ausgebildet sind, wie dies beispielsweise auch für die Räder der Radsätze 11 und 12 der Fall sein kann.It should be added that the wheels 20, 21, 22 and 23 acting as friction wheels are preferably designed as tire wheels, as can also be the case for the wheels of the wheel sets 11 and 12, for example.

Es kann erwünscht sein, den Abstand der Fahrzeuge beim Durchgang durch die Station wieder einem vorgegebenen einheitlichen Takt (Zeitintervall zwischen zwei sich folgenden Fahrzeugen) anzupassen. In einem solchen Fall kann parallel zum Kettenförderer 13 ein Taktförderer an der Ueberführungsstrecke 8 angeordnet sein, wie in der schweizerischen Patentanmeldung Nr. 05105/86 beschrieben (Datum der Anmeldung: 18.12.86).It may be desirable to adapt the distance between the vehicles as they pass through the station to a predetermined uniform cycle (time interval between two vehicles following one another). In such a case, a clock conveyor can be arranged on the transfer line 8 parallel to the chain conveyor 13, as described in Swiss patent application No. 05105/86 (date of application: December 18, 1986).

Claims (6)

1.
