- Systems are used in which the motor vehicles are picked up with telescopic forks after they have been placed on pallets or roller pallets. The pallets are placed in a shelf compartment by a storage and retrieval machine with telescopic forks.

- the telescopic fork lower parts can be tilted in the longitudinal direction with respect to the load carrier after an adjustable tilting moment has been exceeded.
- This arrangement enables the telescopic fork upper parts to be pushed out without support at the beginning of the Pushing out process and causes a smooth transition to supporting the ends of the upper parts of the telescopic fork when the amount of inclination is exceeded and a gradual increase in the weight portions supported by the support rollers with advancing telescoping.
- sensors are provided for monitoring the tilting movement and the feed movement of the upper part of the telescopic fork is switched off when a predetermined inclination amount is exceeded.

Description
Die Erfindung bezieht sich auf eine als Regalbediengerät oder ähnlich gestaltetes verfahrbares Hubgerät ausgebildete Lastaufnahmeeinrichtung insbesondere für Kraftfahrzeuge in mechanischen Parkanlagen gemäß den Oberbegriff des Anspruchs 1.The invention relates to a load-lifting device designed as a storage and retrieval device or a similarly designed movable lifting device, in particular for motor vehicles in mechanical parking systems according to the preamble of
Eine solche Einrichtung ist beispielsweise aus der GB-A-922 075 bekanntSuch a device is known for example from GB-A-922 075
Um Kraftfahrzeuge etwa in Städten platzsparend zu parken, werden automatisierte Parkhäuser betrieben, beispielsweise solche, die nach Art eines Hochregallagers gestaltet sind. Mit automatischen Fördermitteln wird das zu parkende Kraftfahrzeug vom Benutzer an einem Übergabeplatz abgestellt, von einer mechanischen Einrichtung übernommen und im Parkhaus in einem Regalfach eingelagert. Auf Anforderung des Benutzers wird das Kraftfahrzeug vom Lagerfach abgeholt und an einem Auslagerplatz dem Benutzer wieder zur Verfügung gestellt. Dabei werden Systeme eingesetzt, bei denen die Kraftfahrzeuge mit Teleskopgabeln aufgenommen werden, nachdem sie auf Paletten oder Rollpaletten abgestellt worden sind. Die Paletten werden von einem Regalbediengerät mit Teleskopgabeln in ein Regalfach gestellt. Der relativ einfachen Handhabung beim Einlagern stehen hohe Investitionskosten bei den Paletten gegenüber; unerwünscht hoch ist auch der Zeitbedarf und Raumbedarf für das Handhaben und Lagern der Paletten. Das Rollpalettensystem in der Form, daß eine erste in ein Regalfach gestellte Rollpalette von einer zweiten, an sie angekoppelten Rollpalette tiefer in das Regalfach geschoben wird, diese beiden von einer dritten noch weiter usw., bringt zwar eine gute Raumausnutzung mit sich. Ein wesentlicher Nachteil liegt jedoch in der eingeschränkten Zugriffsbereitschaft und damit hohen Zeitdauer von der Anforderung durch die Benutzer bis zur Bereitstellung. Es sind ferner Systeme bekannt, bei welchen verstellbare Rollen an den Rädern angreifen, um das Fahrzeug anzuheben. Wenn dabei die Rollfähigkeit der Kraftfahrzeuge genutzt wird, können eingebremste Fahrzeuge sowie solche mit eingerasteter Lenkradsperre nicht bedient werden. Erwünscht ist jedoch, die Fahrzeuge generell mit angezogener Bremse einzulagern, weil andernfalls im Stellplatz Vorrichtungen geschaffen werden müssen, die ein Wegrollen der Fahrzeuge unterbinden. Außerdem werden sogenannte Krabbelwagen oder Satellitenwagen verwendet. Das sind niedrige Fahrzeuge, auch in Form von Hubfahrzeugen, welche sich von einem sie tragenden und in der Regalgasse verfahrenden Regalbediengerät loslösen und sich auf einer Fahrbahn abstützend unter die Kraftfahrzeuge fahren, diese mit einklappbaren Schub- oder Anhubrollen an den Rädern schieben und halten oder anheben und auf das Regalbediengerät zurückfahren. Im Regal verläßt der Krabbelwagen erneut das Regalbediengerät und setzt das zu parkende Fahrzeug im Regalfach ab. Das setzt voraus, daß im Regalfach neben den für das abzustellende Fahrzeug erforderliche Abstellbalken, den sogenannten Tiefenauflagern, für den Krabbelwagen eigene Fahrschienen vorhanden sein müssen, bei der Vielzahl von Stellplätzen eine hohe zusätzliche Investition. Zudem ist ein Krabbelwagen mit einem eigenen Fahr- und einem Hubantrieb auszustatten, welche im Standard-Lichtraum unter einem Kraftfahrzeug nicht unterzubringen sind. Dadurch und durch die ungünstigere Krafteinleitung in die Bauteile des Regals sind erhöhte Regalkosten und Raumkosten bedingt.In order to park motor vehicles in a space-saving manner, for example, automated parking garages are operated, for example those designed in the manner of a high-bay warehouse. With automatic funding, the motor vehicle to be parked is parked by the user at a transfer point, taken over by a mechanical device and stored in a shelf compartment in the parking garage. At the request of the user, the motor vehicle is picked up from the storage compartment and made available to the user again at a storage location. Systems are used in which the motor vehicles are picked up with telescopic forks after they have been placed on pallets or roller pallets. The pallets are placed in a shelf compartment by a storage and retrieval machine with telescopic forks. The relatively simple handling during storage is offset by high investment costs for the pallets; the time and space required for handling and storing the pallets is also undesirably high. The roller pallet system in the form that a first roller pallet placed in a shelf is pushed deeper into the shelf by a second roller pallet coupled to it, these two even further by a third etc., does indeed make good use of space. A major disadvantage, however, lies in the limited access and therefore a long time from the request by the user to the provision. Systems are also known in which adjustable rollers engage the wheels in order to raise the vehicle. If the rolling ability of the motor vehicles is used, braked vehicles and vehicles with a locked steering wheel lock cannot be operated. However, it is desirable to generally store the vehicles with the brakes applied, because otherwise devices must be created in the parking space to prevent the vehicles from rolling away. So-called crawling or satellite cars are also used. These are low-profile vehicles, also in the form of lifting vehicles, which detach themselves from a storage and retrieval machine that supports them and travels in the aisle and support themselves under the motor vehicles on a lane, pushing and holding or lifting them with retractable pushing or lifting rollers on the wheels and drive back to the storage and retrieval machine. The crawler trolley leaves the storage and retrieval unit on the shelf and places the vehicle to be parked in the shelf compartment. This presupposes that in addition to the parking beams required for the vehicle to be parked, the so-called depth supports, there must be separate rails for the crawler, with the large number of parking spaces a high additional investment. In addition, a baby crawler must be equipped with its own travel and lifting drive, which cannot be accommodated in the standard clearance under a motor vehicle. This and the less favorable introduction of force into the components of the shelf result in increased shelf costs and space costs.
Es ist Aufgabe der vorliegenden Erfindung, die erläuterten Nachteile der bekannten Parksysteme zu vermeiden und dazu eine wirtschaftlicher und universell einsetzbare Lastaufnahmeeinrichtung zu schaffen. Danach wird für eine Lastaufnahmeeinrichtung der eingangs angegebenen Art vorgeschlagen, daß auf einem fahrbaren Lastträger zwei parallel liegende Teleskopgabelunterteile and zueinder quer verschieblich angeordnet sind, deren jedes ein längsteleskopierbares Teleskopgabeloberteil trägt, auf dem zwei Paare von Rollenschlitten mit lastaufnahmeseitig auskragenden Tragrollen längsverfahrbar und gegeneinander verstell- und verriegelbar sind. Dadurch ergibt sich die Möglichkeit, beliebig gestaltete Kraftfahrzeuge durch Längsverfahren der Teleskopgabeloberteile außen oder innen an den Rädern der zu parkenden Kraftfahrzeuge entlang und Querverschieben der Tragrollen in die Flucht der Räder aufzunehmen und lediglich durch Handhabung mittels der Lastaufnahmeeinrichtung einzuparken. Zusätzliche Paletten, Fahrschienen, Antriebe o.dgl. werden nicht benötigt. Die Ein- und Ausparkzeit ist durchschnittlich sehr kurz. Die erforderlichen Investitionskosten sind verhältnismäßig gering.It is an object of the present invention to avoid the disadvantages of the known parking systems and to create an economical and universally applicable load suspension device. After that It is proposed for a load-bearing device of the type specified at the outset that two parallel telescopic fork lower parts and two mutually transversely displaceable parts are arranged on a mobile load carrier, each of which carries a longitudinally telescopic upper fork part on which two pairs of roller slides with supporting rollers projecting on the load-bearing side are longitudinally movable and mutually adjustable and lockable are. This results in the possibility of accommodating motor vehicles of any design by longitudinally moving the upper parts of the telescopic fork on the outside or inside of the wheels of the motor vehicles to be parked and shifting the support rollers transversely into the alignment of the wheels and only parking them by handling by means of the load suspension device. Additional pallets, rails, drives or the like. are not needed. The parking time is very short on average. The investment costs required are relatively low.
Für eine Erhöhung der Tragfähigkeit und einen zuverlässigen Betrieb bei der Lastaufnahme ist jedes Teleskopgabeloberteil in einem die Verbindung zwischen Ober- und Unterteil herstellenden Teleskopgabelmittelteil geführt.To increase the load-bearing capacity and ensure reliable operation when lifting loads, each upper part of the telescopic fork is guided in a central part of the telescopic fork that creates the connection between the upper and lower part.
Weiter sind die Teleskopgabeloberteile mindestens an ihrem freien Ende je mit einer vorzugsweise in einer Linie mit den Tragrollen liegenden Stützrolle ausgestattet. Über die Stützrollen stützen sich die ausgeschobenen Teleskopgabeloberteile auf der ohnehin zur Verfügung stehenden Aufstandsfläche der einzuparkenden oder eingeparkten Kraftfahrzeuge ab und können daher wesentlich leichter als ohne eine solche Abstützung bemessen sein.Furthermore, the upper parts of the telescopic fork are each equipped, at least at their free end, with a support roller which is preferably in line with the support rollers. The extended telescopic fork upper parts are supported by the support rollers on the already available contact surface of the vehicles to be parked or parked and can therefore be dimensioned much more easily than without such a support.
Zweckmäßig sind die Tragrollen jedes Paares von Rollenschlitten in Lastaufnahmestellung gegeneinander verriegelbar.The carrying rollers of each pair of roller slides are expediently lockable against one another in the load suspension position.
In bevorzugter Ausgestaltung der Erfindung ist für das Verfahren und die Verriegelung mehrerer Rollenschlitten, und zwar entweder aller Rollenschlitten oder vor allem jeweils der Rollenschlitten eines Teleskopgabeloberteils, eine einzige Antriebsanordnung vorgesehen. Letztere stellt beim Aufnehmen der einzuparkenden Kraftfahrzeuge zunächst die Tragrollenpaare einer Fahrzeugseite auf den Achsabstand der Räder und die Tragrollen jedes Tragrollenpaares auf die jeweils vordere und rückwärtige Anlage an dem betreffenden Rad ein, fährt dann die Tragrollen jedes Tragrollenpaares gegeneinander, bis das Kraftfahrzeug angehoben ist, und verriegelt die Tragrollen in dieser Lage gegeneinander, bis das Kraftfahrzeug wieder abgesetzt wird. Auf diese Weise ist eine zwanglose und schonende Aufnahme aller Kraftfahrzeuge an ihren Rädern gewährleistet.In a preferred embodiment of the invention, a single drive arrangement is provided for the method and the locking of a plurality of roller slides, namely either all roller slides or especially the roller slides of an upper part of a telescopic fork. The latter, when picking up the motor vehicles to be parked, first sets the idler pairs on one side of the vehicle to the center distance of the wheels and the idlers of each idler pair on the respective front and rear system on the wheel in question, then drives the idlers of each idler pair against each other until the vehicle is raised, and locks the idlers in this position against each other until the motor vehicle is set down again. In this way, an informal and gentle reception of all motor vehicles on their wheels is guaranteed.
Außerdem wird vorgeschlagen, daß die Rollenschlitten je mit mehreren miteinander über gelenkige Glieder verbundenen Tragrollen versehen sind, wobei eine der Form der Last angepaßte Abstützung vorgesehen ist. Damit läßt sich eine Vielpunktabstützung eines jeden Rades erreichen, die zu einer weiteren Entlastung der Radführungen des Kraftfahrzeuges und zu einer gleichmäßigeren Lastverteilung auf den Rollenschlitten führt, vor allem aber die Reibung beim Gegeneinanderfahren der Rollenschlitten der Rollenschlittenpaare zum Anheben des Kraftfahrzeuges wesentlich herabsetzt.In addition, it is proposed that the roller carriages are each provided with a plurality of supporting rollers which are connected to one another via articulated links, with a support which is adapted to the shape of the load being provided. This allows a multi-point support of each wheel to be achieved, which leads to a further relief of the wheel guides of the motor vehicle and to a more uniform load distribution on the roller slides, but above all significantly reduces the friction when the roller slides move against one another for lifting the motor vehicle pairs.
Erfindungsgemäß empfiehlt sich darüber hinaus, daß die Teleskopgabelunterteile gegenüber dem Lastträger nach Überschreiten eines einstellbaren Kippmomentes um einen geringen Neigungsbetrag in Längsrichtung kippbar sind. Diese Anordnung ermöglicht ein abstützungsfreies Ausschieben der Teleskopgabeloberteile zu Beginn des Ausschiebevorganges und bewirkt einen weichen Übergang auf eine Abstützung der Enden der Teleskopgabeloberteile mit dem Überschreiten des Neigungsbetrages und eine allmähliche Erhöhung der über die Stützrollen abgestützten Gewichtsanteile mit fortschreitendem Teleskopieren.According to the invention, it is also recommended that the telescopic fork lower parts can be tilted in the longitudinal direction with respect to the load carrier after an adjustable tilting moment has been exceeded. This arrangement enables the telescopic fork upper parts to be pushed out without support at the beginning of the Pushing out process and causes a smooth transition to supporting the ends of the upper parts of the telescopic fork when the amount of inclination is exceeded and a gradual increase in the weight portions supported by the support rollers with advancing telescoping.
Dabei ist es vorteilhaft, wenn für die Überwachung der Kippbewegung Sensoren vorgesehen sind und bei Überschreiten eines vorgegebenen Neigungsbetrages eine Abschaltung der Vorschubbewegung des Teleskopgabeloberteils erfolgt. Diese Sicherungsanordnung sorgt für eine Unterbrechung der Teleskopierbewegungen, wenn bei benötigter Abstützung der Teleskopgabeloberteile eine Störung der Abstützung auftritt.It is advantageous if sensors are provided for monitoring the tilting movement and the feed movement of the upper part of the telescopic fork is switched off when a predetermined inclination amount is exceeded. This securing arrangement ensures an interruption of the telescopic movements if a disturbance of the support occurs when the upper parts of the telescopic fork are required to be supported.

Eine als Regalbediengerät zur Aufnahme von Kraftfahrzeugen in mechanischen Parkanlagen ausgebildete Lastaufnahmeeinrichtung umfaßt einen Lastträger 1, auf dem zwei sich parallel zueinander erstreckende Teleskopgabelunterteile 2 angeordnet sind. Gegenüber jedem dieser Teleskopgabelunterteile 2 ist ein Teleskopgabelmittelteil 3 und diesem gegenüber ein Teleskopgabeloberteil 4 längsverschieblich und teleskopierbar. Die Teleskopgabelunterteile 2 sind auf dem Lastträger 1 zur Abstandsänderung querverschieblich. Außerdem sind sie in Längsrichtung um einen geringen Neigungsbetrag kippbar, wobei bei Überschreiten eines vorgegebenen Neigungsbetrages über einen Signalgeber Teleskopierbewegungen unterbrochen werden. Jedes Teleskopgabeloberteil 4 trägt seitlich auskragende Stützrollen 5 sowie zwei Paare Rollenschlitten 6, die mit ebenfalls seitlich auskragenden Tragrollen 7 zur Aufnahme von Rädern 8 zu parkender Kraftfahrzeuge versehen sind. Statt einzelner Tragrollen 7 können gemäß Fig. 4 gegebenenfalls über gelenkige Glieder miteinander verbundene Gruppen von Tragrollen 9 den Rollenschlitten 6 zugeordnet sein. Die Querverschiebung der Teleskopgabelunterteile 2 erfolgt über Verschiebeantriebe in Richtung der Pfeile a, die Längsbewegung der Rollenschlitten 6 über Zustellantriebe 10 in Richtung der Pfeile b. Für die Verriegelung der Rollenschlitten 6 sind Zahnleisten 11 vorgesehen.A trained as a storage and retrieval unit for receiving motor vehicles in mechanical parking facilities Load suspension device comprises a
Ein Parkvorgang spielt sich beispielsweise folgendermaßen ab:
- 1. Ein Kraftfahrzeug wird an der Einlagerungsstelle vom Fahrer so abgestellt, daß ein Radpaar, vorzugsweise die Vorderräder, an einer bestimmten Stelle stehen. Das Kraftfahrzeug wird eingebremst und verlassen. Das Kraftfahrzeug steht dabei
mit den Rädern 8 auf Platten, welche eine seitliche Verschiebung, etwa über Kugelleisten, ohne wesentlichen Widerstand zulassen. - 2. Eine Ausricht- und Zentriereinrichtung drückt von außen an die
Reifen der Räder 8 und stellt das Kraftfahrzeug parallel und mittig zur Achse derTeleskopgabelunterteile 2. - 3.
Die Teleskopgabeloberteile 4 der Lastaufnahmeeinrichtung werden in zusammengefahrenem Zustand unter das Kraftfahrzeug gefahren. Die auf ihnen längsverschieblich angeordneten Rollenschlitten 6 sind dabei maximal voneinander entfernt. Sensoren überwachen während des Unterfahrens das Vorhandensein ausreichenden Freiraumes unter dem Kraftfahrzeug. - 4.
Die Teleskopgabelunterteile 2 und mit ihnen die austeleskopierten Teleskopgabeloberteile 4 werden auseinandergefahren, wobei dieaus den Rollenschlitten 6herausragenden Tragrollen 7 sowie auch dieStützrollen 5 in die Spur des Fahrzeuges rücken. Sensoren überwachen die Spreizbewegung und schalten sie vor einer Berührung zwischendem Teleskopgabeloberteil 4 und den Reifen ab. - 5. Mechanische Antriebe
verstellen die Rollenschlitten 6 paarweise aufeinander zu.Die Tragrollen 7 heben dadurch das Kraftfahrzeug an. Mit dem Anheben des Kraftfahrzeugs erhöht sich das Biegemoment in den Teleskopgabelteilen. Die anden Teleskopgabeloberteilen 4angebrachten Stützrollen 5 begrenzen die auftretende Biegeverformung, indem sie sich in der Spur des Kraftfahrzeuges abstützen. - 6.
Die Teleskopgabeloberteile 4 werden eingefahren. Das angehobene Kraftfahrzeug befindet sich nun aufdem Lastträger 1 des Regalbediengerätes. - 7. Das Regalbediengerät verfährt in der Regalgasse und stellt
den Lastträger 1 mit den Teleskopgabelteilen und dem darauf befindlichen Kraftfahrzeug vor ein leeres Regalfach. - 8.
Die Teleskopgabeloberteile 4 fahren ins Regalfach, wobei sich die Stützrollen 5 - mit zunehmender Ausfahrlänge mehr und mehr - auf dem Tiefenauflager des Regalfaches abstützen. - 9.
Die Rollenschlitten 6 werden auseinandergefahren, nachdem ihre Blockierung aufgehoben wurde. Dabei werden dieRäder 8 auf die Tiefenauflager abgesetzt. - 10.Die Teleskopgabelteile werden unter dem Kraftfahrzeug quer zusammengefahren und anschließend längs eingefahren.
- 11.Die Lastaufnahmeeinrichtung ist frei für einen neuen Arbeitsgang.
- 1. A motor vehicle is parked at the storage location by the driver so that a pair of wheels, preferably the front wheels, are at a certain point. The motor vehicle is braked and left. The motor vehicle stands with the
wheels 8 on plates which allow lateral displacement, for example over ball bars, without substantial resistance. - 2. An alignment and centering device presses on the tires of the
wheels 8 from the outside and places the motor vehicle parallel and centrally to the axis of the telescopic forklower parts 2. - 3. The telescopic fork
upper parts 4 of the load suspension device are moved under the motor vehicle in the collapsed state. The roller slides 6 arranged on them so as to be longitudinally displaceable are at a maximum distance from one another. Sensors monitor the presence of sufficient free space under the motor vehicle during the drive-under. - 4. The lower
telescopic fork parts 2 and with them the telescopedupper parts 4 of the telescopic fork are moved apart, thesupport rollers 7 protruding from theroller carriages 6 and also thesupport rollers 5 moving into the track of the vehicle. Sensors monitor the spreading movement and switch it off before touching theupper part 4 of the telescopic fork and the tires. - 5. Mechanical drives move the
roller carriages 6 towards each other in pairs. Thesupport rollers 7 thereby raise the motor vehicle. When the motor vehicle is lifted, the bending moment in the telescopic fork parts increases. Thesupport rollers 5 attached to the telescopic forkupper parts 4 limit the bending deformation that occurs by being supported in the track of the motor vehicle. - 6. The telescopic fork
upper parts 4 are retracted. The raised motor vehicle is now on theload carrier 1 of the storage and retrieval unit. - 7. The storage and retrieval machine moves in the rack aisle and places the
load carrier 1 with the telescopic fork parts and the motor vehicle thereon in front of an empty rack compartment. - 8. The telescopic fork
upper parts 4 move into the shelf compartment, thesupport rollers 5 being supported on the deep support of the shelf compartment as the extension length increases. - 9. The roller slides 6 are moved apart after their blocking has been released. The
wheels 8 are placed on the depth supports. - 10.The telescopic fork parts are moved together across the vehicle and then retracted lengthways.
- 11.The load suspension device is free for a new operation.
Eine Auslagerung verläuft in angepaßt umgekehrter Reihenfolge.Outsourcing is done in the reverse order.
Bei einer Ausgestaltung der Lastaufnahmeeinrichtung mit von außen am Kraftfahrzeug angreifenden Teleskopgabeloberteilen spielt sich der Parkvorgang sinngemäß entsprechend ab.In the case of a configuration of the load suspension device with telescopic fork upper parts acting on the outside of the motor vehicle, the parking process takes place accordingly.
