Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Transportieren von Gütern mit einer Schienenfahrbahn, die gegenüber einer Arbeitsebene erhöht in einer Transportebene verlaufend angelegt ist, insbesondere mit einer an bzw. im Bereich der Decke eines Arbeitsraumes verlegten Schienenfahrbahn, und mit einer Mehrzahl von Laufwagen, die entlang dieser Schienenfahrbahn in der Transportebene bewegbar sind, wobei diese Schienenfahrbahn an vorbestimmten Stellen Abschnitte aufweist, die aus der Transportebene heraus in den Bereich der Arbeitsebene, insbesondere in den Bereich des Fussbodens des Arbeitsraumes, absenkbar sind.The present invention relates to a device for transporting goods with a railroad track, which is designed to run higher than a working level in a transport plane, in particular with a railroad track laid on or in the area of the ceiling of a work area, and with a plurality of carriages running along it This rail track can be moved in the transport plane, said rail track having sections at predetermined points which can be lowered out of the transport plane into the area of the working plane, in particular into the area of the floor of the working area.

Die Laufwagen solcher Transportvorrichtungen können z.B. einfache, stangenartige Elemente sein, die mit Rädern ausgerüstet sind, welche auf der Schienenfahrbahn abrollen. An diese Laufwagen-Elemente können Lastaufnahmeorgane angehängt sein, z.B. in der Form von Körben, Plattformen und dgl., welche die zu transportierenden Güter aufnehmen, oder die Güter können direkt an den Laufwagen-Elementen angehängt werden. Auf diese Weise können die Güter einfach und platzsparend von einem Arbeitsplatz zu einem anderen verschoben werden. Der Transport der Güter erfolgt dabei in einer ersten, hochgelegenen Ebene oberhalb der Arbeitsplätze, insbesondere im Bereich der Decke eines Arbeitsraumes, während die Bearbeitung bzw. Weiterverarbeitung der Güter üblicherweise in einer zweiten, tiefer gelegenen Arbeitsebene erfolgt, insbesondere im Bereich des Fussbodens des Arbeitsraumes.The carriages of such transport devices can e.g. be simple, rod-like elements that are equipped with wheels that roll on the railroad track. Load-carrying elements can be attached to these carriage elements, e.g. in the form of baskets, platforms and the like, which accommodate the goods to be transported, or the goods can be attached directly to the carriage elements. In this way, the goods can be moved easily and space-saving from one workplace to another. The goods are transported on a first, higher level above the workplaces, especially in the area of the ceiling of a work area, while the processing or further processing of the goods is usually carried out on a second, lower level, in particular in the area of the floor of the work area.

Es leuchtet ein, dass im Bereich der einzelnen Arbeitsplätze eine im wesentlichen vertikale Verschiebung der Güter von der ersten, hochgelegenen Ebene hinunter in den Bereich der Arbeitsebene erfolgen muss. Dies wird nach bekannter Art dadurch erreicht, dass die Schienenfahrbahn an vorbestimmten Stellen Senk- und Hubstationen aufweist, d.h. Abschnitte der Schienenfahrbahn, die aus der Transportebene heraus in die Arbeitsebene absenkbar sind. Praktisch wird dabei ein Laufwagen, der die an einer bestimmten Bearbeitungsstelle erforderlichen Güter enthält bzw. trägt, in denjenigen senk- und hebbaren Abschnitt der Schienenfahrbahn verschoben, der über dieser genannten Arbeitsstelle liegt, dann dort gegen Weiterverschieben arretiert und mitsamt dem erwähnten Abschnitt abgesenkt. Nach erfolgtem Bearbeiten der Güter wird der Laufwagen, sei er nun leer oder aber mit den zwischenbearbeiteten Gütern versehen, mitsamt dem erwähnten Abschnitt wieder in die Transportebene gehoben, die Arretierung gelöst und auf der Schienenfahrbahn zu einer nächsten Arbeitsstelle verschoben.It is obvious that in the area of the individual workplaces there must be an essentially vertical shift of the goods from the first, high level down to the area of the work level. This is achieved in a known manner in that the rail track has lowering and lifting stations at predetermined locations, i.e. Sections of the railroad track that can be lowered from the transport level into the working level. Practically, a carriage that contains or carries the goods required at a certain processing point is moved into that lowerable and liftable section of the railroad track that lies above this mentioned working position, then locked there against further movement and lowered together with the mentioned section. After the goods have been processed, the carriage, whether empty or provided with the intermediate goods, together with the section mentioned, is lifted back into the transport level, the lock released and moved to a next job on the railroad track.

Eine Vorrichtung zum Transportieren von Gütern der eingangs genannten Art ist aus der DE-OS 32 41 744 bekannt. Bei der dort gezeigten Vorrichtung hat der senk- und hebbare Abschnitt der Schienenfahrbahn eine Länge, die nur ausreicht, um einen einzigen Laufwagen aufzunehmen. Dies bedeutet, - und ist aus Sicherheitsgründen auch unbedingt erforderlich-, dass nach dem Hochheben der Senk-und Hubstation der erwähnte Abschnitt vollständig vom vorherigen Laufwagen geräumt und die Endarretierung wieder in Funktion sein muss, bevor der weitere, in den meisten Fällen bereits wartende Laufwagen auf den senk- und hebbaren Abschnitt verschoben und zusammen mit diesem wieder abgesenkt werden kann.A device for transporting goods of the type mentioned is known from DE-OS 32 41 744. In the device shown there, the lowerable and liftable section of the rail track has a length which is only sufficient to accommodate a single carriage. This means - and is also absolutely necessary for safety reasons - that after the lowering and lifting station has been lifted up, the section mentioned must be completely cleared of the previous carriage and the final locking function must be in place again before the further carriage, which in most cases is already waiting can be moved to the lowerable and liftable section and lowered together with it.

Wie schon erwähnt, kann dieser Vorgang, d.h. das Ausschleusen des Laufwagens mit den bearbeiteten Gütern (oder ev. eines leeren Laufwagens) und das Einschleusen des nachfolgenden Laufwagens in die Senk- und Hubstation aus Sicherheitsgründen nicht gleichzeitig erfolgen, es sei denn, man nimmt ein wesentlich vergrössertes Sicherheitsrisiko und/oder einen bedeutend erhöhten, technischen Aufwand in Kauf. Die Folge davon sind grössere, grob gesagt verdoppelte Wartezeiten, bis ein neuer Laufwagen wieder auf der Arbeitsebene zur Verfügung steht, was sich in Produktionsausfällen bzw. einer geringeren Produktivität niederschlägt.As already mentioned, this process, i.e. for safety reasons, the carriage of the carriage with the processed goods (or possibly an empty carriage) and the subsequent carriage into the lowering and lifting station do not take place at the same time, unless one takes a significantly increased safety risk and / or a significantly increased one , technical effort in purchase. The consequence of this is longer, roughly doubled waiting times until a new carriage is available again at the work level, which is reflected in production downtimes or lower productivity.

Es ist die Aufgabe der vorliegenden Erfindung, diesen Nachteil zu vermeiden und eine Vorrichtung der eingangs genannten Art so auszubilden, dass sie ohne Einbusse an Sicherheit ein rascheres Ein-und Ausschleusen der Laufwagen in die Senk- und Hubstation ermöglicht. Ausserdem soll ein Verfahren zum Betrieb der Vorrichtung angegeben werden.It is the object of the present invention to avoid this disadvantage and to design a device of the type mentioned at the outset in such a way that it allows the carriages to be introduced and removed more rapidly into the lowering and lifting station without sacrificing safety. In addition, a method for operating the device is to be specified.

Gemäss der Erfindung wird diese Aufgabe dadurch gelöst, dass die Länge der senk- und hebbaren Abschnitte der Schienenfahrbahn zumindest der doppelten Länge eines Laufwagens, in dessen Bewegungsrichtung gemessen, entspricht.According to the invention, this object is achieved in that the length of the sections of the rail track that can be lowered and raised corresponds to at least twice the length of a carriage, measured in the direction of its movement.

Damit kann sichergestellt werden, dass der Laufwagen mit den bearbeiteten Gütern bzw. ein leerer Laufwagen vom senk- und hebbaren Abschnitt entfernt bzw. ausgeschleust werden kann, währenddem der nächste Laufwagen gleichzeitig in die Senk- und Hubstation eingefahren wird. Mit anderen Worten gesagt, der senk- und hebbare Abschnitt der Schienenfahrbahn bietet für zwei Laufwagen Platz, indem einem zu hebenden Laufwagen ein anderer Platz zugeteilt wird als einem zu senkenden Laufwagen. Die Ein- und Ausschleusvorgänge der Laufwagen sind damit räumlich voneinander getrennt, d.h. diese beiden Operationen können nunmehr gleichzeitig erfolgen, was eine bedeutende Zeitersparnis mit sich bringt.This ensures that the carriage with the processed goods or an empty carriage can be removed from the lowerable and liftable section or can be removed while the next carriage is being moved into the lowering and lifting station at the same time. In other words, the section of the rail track that can be lowered and raised provides space for two carriages by allocating a different space to a carriage to be lifted than a carriage to be lowered. The infeed and outfeed processes of the carriages are thus spatially separated, i.e. these two operations can now be done simultaneously, which saves a significant amount of time.

Bevorzugte Ausführungsformen und Weiterbildungen des Erfindungsgegenstandes sind in den abhängigen Patentansprüchen 2 bis 6 umschrieben.Preferred embodiments and developments of the subject matter of the invention are described in the dependent claims 2 to 6.

Die Erfindung betrifft ferner ein Verfahren zum Betrieb einer derartigen Vorrichtung, die bezüglich einer Senk- und Hubstation mit einer Länge von zwei Laufwagen-Längen durch die Merkmale des Patentanspruchs 7 und bezüglich einer Senk- und Hubstation mit einer Länge von mehr als zwei Laufwagen-Längen durch die Merkmale des Patentanspruchs 8 gekennzeichnet ist.The invention further relates to a method for operating such a device, with respect to a lowering and lifting station with a length of two carriage lengths by the features of claim 7 and with respect to a lowering and lifting station with a length of more than two carriage lengths is characterized by the features of claim 8.

Im folgenden wird die erfindungsgemässe Vorrichtung anhand der beiliegenden, schematischen Skizze und das erfindungsgemässe Verfahren beispielshaft erläutert.In the following, the device according to the invention is explained by way of example with reference to the enclosed schematic sketch and the method according to the invention.

In der einzigen Zeichnung ist schematisch ein Ausschnitt aus einer Fördervorrichtung zum Transportieren von Gütern dargestellt. Diese weist eine in einer Transportebene z.B. im Bereich der Decke 1 eines Arbeitsraumes 2 angeordnete Schienenfahrbahn 3 auf. Im Bereich einer Arbeitsstelle 4, die in einer Arbeitsebene, z.B. auf dem Fussboden 7 des Arbeitsraumes 2 vorgesehen ist, ist die Schienenfahrbahn 3 durch einen senk- und hebbaren Abschnitt 5 unterbrochen. Dieser Abschnitt 5 ist, wie ausgezogen gezeichnet, von einer gehobenen Stellung, in der er eine Fortsetzung bzw. ein durchgehendes Teil der Schienenfahrbahn 3 bildet, in eine gestrichelt gezeichnete, abgesenkte Stellung verschiebbar; dies unter Wirkung von nicht näher dargestellten, an sich bekannten Antriebsmitteln.In the single drawing, a section of a conveyor device for transporting goods is shown schematically. This has a in a transport level e.g. in the area of the ceiling 1 of a work space 2 arranged rail track 3. In the area of a work station 4, which is located on a work level, e.g. is provided on the floor 7 of the working space 2, the rail track 3 is interrupted by a section 5 which can be raised and lowered. This section 5, as drawn drawn, can be moved from a raised position, in which it forms a continuation or a continuous part of the rail track 3, into a lowered position shown in broken lines; this under the action of known drive means, not shown,.

Entlang der Schienenfahrbahn 3 sind Laufwagen 6 verfahrbar, die ebenfalls an sich bekannt sind und z.B. durch ein längliches Gestell mit sich auf den Schienen der Fahrbahn 3 abwälzenden, nicht dargestellten Rollen entlang der Fahrbahn 3 verschiebbar sind. An den Laufwagen 6 sind im Beispielsfall Tragkörbe 8 angehängt, die Güter aufnehmen, welche an der Arbeitsstelle 4 zu verarbeiten bzw. weiterzubearbeiten sind.Carriages 6 can be moved along the rail track 3, which are also known per se and e.g. are displaceable along the carriageway 3 by means of an elongated frame with rollers (not shown) which roll on the rails of the carriageway 3. In the example, support baskets 8 are attached to the carriage 6, which hold goods which are to be processed or further processed at the work station 4.

Die Bewegungsrichtung der Laufwagen 6 entlang der Schienenfahrbahn 3 ist mit den Pfeilen "EIN" und "AUS" bezeichnet.The direction of movement of the carriages 6 along the rail track 3 is indicated by the arrows "ON" and "OFF".

Im Bereich der Einfahrstelle zur Senk- und Hubstation ist die Schienenfahrbahn mit einer ersten Arretiervorrichtung 9 ausgerüstet, die mit zwei Verriegelungsorganen 9a und 9b versehen ist. Der Abstand dieser Verriegelungsorgane entspricht etwa der Länge eines Laufwagens 6. Auch der senk-und hebbare Abschnitt 5 ist mit zwei Arretierorganen versehen. Ein erstes Arretierorgan 10 ist, in Bewegungsrichtung der Laufwagen 6 gesehen, am Ende des Abschnittes 5 und ein zweites Arretierorgan 11 etwa in der Mitte dieses Abschnittes 5 angeordnet. Beide Arretierorgane können von einer Ruhestellung, in der sie die Bewegung des Laufwagens nicht behindern, in eine Wirkstellung umgestellt werden, in welch letzterer sie eine Weiterbewegung des Laufwagens 6 verhindern. Die Arretiervorrichtung 9 wie auch die beiden Arretierorgane 10 und 11 sind unabhängig voneinander umstellbar, z.B. unter Einfluss einer geeigneten Steuereinheit, die nicht Gegenstand dieser Erfindung bildet.In the area of the entry point to the lowering and lifting station, the rail track is equipped with a first locking device 9, which is provided with two locking members 9a and 9b. The distance between these locking members corresponds approximately to the length of a carriage 6. The lowerable and liftable section 5 is also provided with two locking members. A first locking member 10, as seen in the direction of movement of the carriage 6, is arranged at the end of section 5 and a second locking member 11 approximately in the middle of this section 5. Both locking members can be switched from a rest position, in which they do not hinder the movement of the carriage, into an operative position, in which the latter prevent further movement of the carriage 6. The locking device 9 as well as the two locking members 10 and 11 can be converted independently of one another, e.g. under the influence of a suitable control unit which is not the subject of this invention.

Schliesslich sind noch Rücklaufsperren 12a und 12b, z.B. in der Art einer Klinke vorgesehen: Einerseits ist am in Bewegungsrichtung der Laufwagen gesehen vorderen Ende des Abschnittes 5 eine Sperre 12a und andererseits am Beginn der Fortsetzung der Schienenfahrbahn 3 nach dem Abschnitt 5 eine Sperre 12b angeordnet. Diese beiden Rücklaufsperren verhindern, dass ein Laufwagen 6 entgegen der Richtung der Pfeile "EIN" bzw. "AUS" ver schiebbar ist.Finally, there are backstops 12a and 12b, e.g. provided in the manner of a latch: on the one hand, a lock 12a is arranged at the front end of section 5 as seen in the direction of movement of the carriage, and on the other hand a lock 12b is arranged at the beginning of the continuation of the rail track 3 after section 5. These two backstops prevent a carriage 6 from being pushed against the direction of the arrows "ON" or "OFF".

Die vorstehend beschriebene Vorrichtung wird wie folgt betrieben:
Ein Laufwagen 6, der einen zu bearbeitende Güter enthaltenden Tragkorb 8 mit sich führt, nähert sich in Richtung des Pfeiles "EIN" dem Ende des rechtsseitigen Teils der Schienenfahrbahn 3. Je nachdem, ob an diesem Ende bereits ein Laufwagen in Warteposition ist oder nicht, ist das Verriegelungsorgan 9a in Wirkstellung, wo es den ankommenden Laufwagen aufhält, oder in Ruhestellung, in der es den ankommenden Laufwagen durchfahren lässt bis zum Verriegelungsorgan 9b. Letzteres ist seinerseits entweder in Wirkstellung, wo es den Laufwagen aufhält, z.B. wenn der Abschnitt 5 abgesenkt ist, oder in Ruhestellung, in der es den Laufwagen auf den Abschnitt 5 einfahren lässt. In diesem Fall ist aber das zweite Arretierorgan 11 in Wirkstellung und stoppt den ankommenden Laufwagen 6, sodass dieser in einem ersten Bereich A des Abschnittes 5 aufgenommen ist. Die Rücklaufsperre 12a verhindert dabei eine ungewollte Rückwärtsbewegung des Laufwagens.The device described above is operated as follows:
A carriage 6, which carries a carrier cage 8 to be processed with it, approaches in the direction of the arrow "ON" the end of the right-hand part of the rail track 3. Depending on whether a carriage is already in a waiting position at this end or not, is the locking member 9a in the active position, where it stops the incoming carriage, or in the rest position, in which it lets the incoming carriage pass through to the locking member 9b. The latter in turn is either in the active position where it holds the carriage, for example when section 5 is lowered, or in the rest position in which it allows the carriage to retract onto section 5. In this case, however, the second locking member 11 is in the operative position and stops the arriving carriage 6, so that it is received in a first area A of section 5. The backstop 12a prevents an undesired backward movement of the carriage.

Wir gehen nun beispielsweise davon aus, dass kein Laufwagen in Warteposition vor der Senk- und Hubstation war, sondern dass der ankommende Laufwagen 6 bis in den Bereich A des Abschnittes 5 hineinfahren konnte, wie es in der Zeichnung dargestellt ist. Nun wird jedenfalls das Verriegelungsorgan 9b und vorzugsweise auch das Verriegelungsorgan 9a in Wirkposition gebracht, so dass ein eventuell unmittelbar nachfolgender Laufwagen nicht aufschliessen kann, und der senk- und hebbare Abschnitt 5 kann mitsamt dem Laufwagen 6 von der Transportebene in die Arbeitsebene abgesenkt werden. Dort angekommen werden die im Tragkorb 8 enthaltenen Güter be- oder verarbeitet, eventuell auch nur entnommen. Jedenfalls kann dabei das zweite Arretierorgan 11, egal ob vor oder während der Verarbeitung der Güter, gelöst, d.h. in seine Ruhestellung umgestellt werden, wobei darauf zu achten ist, dass das endseitige Arretierorgan 10 in Wirkstellung ist, um ein Ueberfahren des Abschnittes 5 zu vermeiden, wenn der Laufwagen 6 vom Bereich A in den Bereich B bewegt wird.We now assume, for example, that there was no carriage in the waiting position in front of the lowering and lifting station, but that the arriving carriage 6 could move into area A of section 5, as shown in the drawing. In any case, the locking member 9b and preferably also the locking member 9a are now brought into operative position, so that a carriage that may follow immediately cannot unlock, and the lowerable and liftable section 5 together with the carriage 6 can be lowered from the transport plane into the working plane. Once there, the goods contained in the carrier basket 8 are worked or processed, possibly only removed. In any case, the second locking member 11, whether before or during the processing of the goods, can be released, i.e. be switched to its rest position, it being important to ensure that the end locking element 10 is in the active position in order to avoid overriding of the section 5 when the carriage 6 is moved from the area A to the area B.

Nachdem die Behandlung der Güter abgeschlossen ist, befindet sich der Laufwagen also im Bereich B, und das Arretierorgan 11 in der Mitte des Abschnittes 5 kann wieder betätigt, d.h. in seine Wirkstellung gebracht werden. Falls in der Zwischenzeit ein Laufwagen angekommen ist, der vom betätigten Verriegelungsorgan 9a aufgehalten worden ist, kann diese Verriegelung gelöst werden, so dass jeder Laufwagen bis zum nach wie vor aktiven Verriegelungsorgan 9b weiterfahren kann.After the handling of the goods has been completed, the carriage is therefore in area B and the locking member 11 in the middle of section 5 can be actuated again, i.e. be brought into its operative position. If in the meantime a carriage has arrived that has been stopped by the actuating locking element 9a, this locking can be released so that each carriage can continue to the still active locking element 9b.

Nun wird der senk- und hebbare Abschnitt 5 aus der Arbeitsebene heraus angehoben, bis er wieder die Transportebene erreicht hat. Im Normalfall wird dort bereits ein nachfolgender Laufwagen 6 bereitstehen, der durch das Verriegelungsorgan 9b am Überfahren des Endes des rechtsseitigen Teils der Schienenfahrbahn gehindert worden ist. Sobald der Abschnitt 5 in der Transportebene angelangt ist, werden im wesentlichen gleichzeitig das Arretierorgan 10 und das Verriegelungsorgan 9b gelöst, so dass gleichzeitig der behandelte Laufwagen 6 in Richtung des Pfeiles "AUS" den Bereich B des Abschnittes 5 verlassen und der bereits am Ende des rechtsseitigen Teils der Schienenfahrbahn wartende Laufwagen in Richtung des Pfeiles "EIN" in den Bereich A des Abschnittes 5 einfahren kann. Es versteht sich, dass dabei das Arretierorgan 11 in Wirksteiiung verbleibt. Damit kann der ganze Zyklus von neuem beginnen.Now the lowerable and liftable section 5 is lifted out of the working level until it has reached the transport level again. In the normal case, a subsequent carriage 6 will already be ready there, which has been prevented by the locking member 9b from crossing the end of the right-hand part of the rail track. As soon as the section 5 has reached the transport plane, the locking member 10 and the locking member 9b are released essentially simultaneously, so that the treated carriage 6 in the direction of the arrow "OFF" simultaneously leaves the area B of the section 5 and which already at the end of the carriages waiting on the right-hand side of the railroad track can enter area A of section 5 in the direction of the arrow "ON". It is understood that the locking member 11 in Effective remains. With this, the whole cycle can start again.

Unter Umständen kann es wünschenswert sein, gleichzeitig zwei oder mehr Laufwagen 6 mit zugeordneten Tragkörben 8 an der Arbeitsstelle zur Verfügung zu haben. In diesem Fall muss die Länge des senk- und hebbaren Abschnittes 5 grösser bemessen sein, und zwar so, dass noch erfolgter Behandlung immer zumindest ein freier Aufnahmeplatz (Bereich A) vorhanden ist.Under certain circumstances, it may be desirable to have two or more carriages 6 with associated support baskets 8 available at the workplace at the same time. In this case, the length of the section 5 which can be lowered and raised must be larger, in such a way that at least one free receiving area (area A) is always available during the treatment.

Bei chaotischer Einlagerung, d.h. wenn die Laufwagen in willkürlicher Reihenfolge auf der Schienenfahrbahn 3 ankommen, werden ungewollte Laufwagen nicht abgesenkt, sondern laufen in einem Steuerprogramm "Durchlauf" direkt in die Ausfahrtslinie nach dem senk-und hebbaren Abschnitt 5. Dabei werden die Arretiervorrichtungen in ihrer richtigen Reihenfolge in Wirkbzw. Ruhestellung versetzt.With chaotic storage, i.e. if the carriages arrive on the rail track 3 in an arbitrary order, unwanted carriages are not lowered, but run in a control program "pass" directly into the exit line after the section 5 which can be lowered and raised. The locking devices are in their correct order in action or Rest position.

Dabei kann die Senkvorrichtung abgeschaltet und die Ein- resp. Ausfahrstrecke "als wenn nicht unterbrochen" benützt werden.The lowering device can be switched off and the on or. Exit route "as if not interrupted" can be used.

In der Bearbeitungsebene, oder sonstwo im Senkbereich können weitere Ausfahr-Linien angeschlossen und ggf. bedient werden.Additional exit lines can be connected and operated if necessary on the processing level or elsewhere in the lowering area.
