Description
Die Erfindung betrifft ein Steuerungsverfahren für eine Hubhöhenvorwahl eines Flurförderzeugs. Insbesondere betrifft die Erfindung ein Steuerungsverfahren für eine Hubhöhenvorwahl eines Flurförderzeugs mit einem an einem Hubgerüst höhenbeweglich geführten Lastaufnahmemittel, insbesondere einer Lastgabel, wobei eine bestimmte anzufahrende Hubhöhe ausgewählt werden kann, indem in einem ersten Schritt mit einer Bedienvorrichtung das Lastaufnahmemittel in Richtung auf die anzufahren Hubhöhe bewegt wird und bei Betätigung eines zusätzlichen Schalters, oder alternativ ohne zusätzlichen Schalter bei einer Verringerung der Hubgeschwindigkeit unter einem bestimmten Hubgeschwindigkeitsschwellenwert, die nächste zu erreichende einprogrammierte Hubhöhe ausgewählt wird und an dieser die Hubbewegung automatisch von der Steuerungsvorrichtung gestoppt wird.The invention relates to a control method for a Hubhöhenvorwahl an industrial truck. In particular, the invention relates to a control method for a Hubhöhenvorwahl an industrial truck with a height-movably guided on a mast load handling device, in particular a fork, with a certain approaching lifting height can be selected by the lifting device moves in a first step with an operating device in the direction of approaching the lifting height is and upon actuation of an additional switch, or alternatively without additional switch with a reduction in the lifting speed below a certain Hubgeschwindigkeitsschwellenwert, the next to be reached programmed stroke height is selected and at this the lifting movement is automatically stopped by the control device.
Im Stand der Technik ist bei Flurförderzeugen mit einem an einem Hubgerüst höhenbeweglich geführten Lastaufnahmemittel bekannt, eine Hubhöhenvorwahl vorzusehen. Dabei werden durch einen Benutzer des Flurförderzeugs in einer Eingabevorrichtung oder auf sonstige Weise eine bestimmte oder mehrere Hubhöhen einprogrammiert. Unter diesen kann dann eine eingegebene Hubhöhe ausgewählt werden, die von dem Lastaufnahmemittel automatisch angefahren wird.In the prior art is known in forklift trucks with a height-movably guided on a mast lifting device to provide a Hubhöhenvorwahl. In this case, a specific or several lifting heights are programmed by a user of the industrial truck in an input device or in some other way. Among these, an input lifting height can then be selected, which is automatically approached by the load handling device.
Um jedoch zu vermeiden, dass beispielsweise in einem Eingabemenü eine bestimmte Hubhöhe ausgewählt werden muss, was zu einer umständlichen Auswahl und zu Zeitverzögerungen führt, und da andererseits es aufgrund beschränkter Platzverhältnisse nicht ohne weiteres möglich ist, eine Vielzahl von Auswahltasten für die Auswahl der Hubhöhe vorzusehen, sind alternative Methoden zur Auswahl einer bestimmten Hubhöhe bekannt.However, in order to avoid that, for example, a certain lifting height must be selected in an input menu, which leads to a cumbersome selection and time delays, and on the other hand, it is not readily possible due to limited space to provide a variety of selection buttons for the selection of the lifting height , alternative methods for selecting a specific lifting height are known.
So ist es bekannt, zunächst keine bestimmte Hubhöhe auszuwählen, sondern mit dem Bedienelement das Lastaufnahmemittel anzusteuern und kurz vor Erreichen der auszuwählenden Hubhöhe entweder durch Betätigen eines gesonderten Schaltelement oder aufgrund der Betätigungsweise des Bedienelements, beispielsweise einer Verlangsamung der Hubgeschwindigkeit, die anzufahrende Hubhöhe auszuwählen, indem die als nächste erreichte Hubhöhe als ausgewählt gilt. Sobald diese ausgewählt Hubhöhe dann erreicht wird, stoppt das Lastaufnahmemittel automatisch. Ein solches Stenerverfahren ist in
Weiter ist bei einer Hubhöhenvorwahl zu beachten, dass für jede der Hubhöhen eine solche für das Einlagern und das Auslagern zu unterscheiden ist. Beim Einlagern einer auf einer Palette gelagerten Ware in ein bestimmtes Regalfach eines Hochregals muss das Lastaufnahmemittel mit der Palette so hoch über die Höhe des Regalbodens angehoben sein, dass die Palette in das Regalfach verfahren werden kann und durch Absenken des Lastaufnahmemittels abgesetzt werden kann.Furthermore, it should be noted in the case of a stroke height preselection that one for each of the stroke heights is to be distinguished for storage and retrieval. When storing a stored on a pallet goods in a particular shelf of a high rack, the load-carrying means with the pallet must be raised so high above the height of the shelf that the pallet can be moved into the shelf and can be discontinued by lowering the load-carrying means.
Umgekehrt muss beim Auslagern das Lastaufnahmemittel ca. 15 cm tiefer für dieselbe vorgewählte Hubhöhe stoppen, so dass beispielsweise eine Lastgabel als Lastaufnahmemittel in eine auf dem Regalboden abgesetzte Palette eingeführt werden und durch Anheben des Lastaufnahmemittels die Palette aus dem Regalfach aufgenommen werden kann.Conversely, when retrieving the load-carrying means must stop about 15 cm deeper for the same preselected lifting height, so that, for example, a load fork as load-carrying means are introduced into a set on the shelf pallet and can be picked up by lifting the lifting device, the range from the shelf.
Ein bekannter Vorschlag für die Unterscheidung des Einlagerns gegenüber dem Auslagern ist eine Messung des auf dem Lastaufnahmemittel aufliegenden Gewichts.A well-known proposal for the distinction of storage compared to the outsourcing is a measurement of the resting on the load-carrying weight.
Nachteilig an diesem Stand der Technik ist jedoch, dass es aufgrund des großen Lastbereichs von beispielsweise Gabelstaplern als Flurförderzeugen, die bis zu mehreren Tonnen heben können, zu Fehlbestimmungen kommen kann, beispielsweise wenn nur eine leere Palette als Last aufliegt.A disadvantage of this prior art, however, is that due to the large load range of, for example, forklifts as industrial trucks, which can lift up to several tons, can lead to misappropriation, for example, when only an empty pallet rests as a load.
Weiter ist bekannt, dass durch zusätzliche Schalter jeweils zwischen einem Auslagern und einem Einlagern unterschieden werden kann. Hierfür sind jedoch weitere Schalter oder Tasten nahe an der Bedienvorrichtung erforderlich in einem Bereich, in dem nur wenig Platz zur Verfügung steht. Auch muss ein Bediener oder Fahrer in einer eigenen Hand- bzw. Armbewegung einen solche Schaltmöglichkeit betätigen, was bei einer Vielzahl von Fällen relativ aufwändig ist.It is also known that a distinction can be made by additional switches in each case between an outsourcing and a storage. For this purpose, however, further switches or buttons near the operating device are required in an area in which only little space is available. Also, an operator or driver must operate in a separate hand or arm movement such a switching possibility, which is relatively complex in a variety of cases.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Steuerungsverfahren für eine Hubhöhenvorwahl eines Flurförderzeugs zur Verfügung zu stellen, das eine rasche und einfache Bedienung in Bezug auf die Auswahl einer Hubhöhe ermöglicht.The present invention is therefore an object of the invention to provide a control method for a Hubhöhenvorwahl an industrial truck available that allows quick and easy operation in terms of selecting a lifting height.
Diese Aufgabe wird durch ein Steuerungsverfahren für eine Hubhöhenvorwahl eines Flurförderzeugs mit den Merkmalen der unabhängigen Patentansprüche 1 oder 2 gelöst. Vorteilhafte Weiterbildungen der erfindungsgemäßen Verfahren sind in den Unteransprüchen angegeben.This object is achieved by a control method for a Hubhöhenvorwahl an industrial truck with the features of the independent claims 1 or 2. Advantageous developments of the method according to the invention are specified in the subclaims.
Die Aufgabe wird dadurch gelöst, dass bei einem Steuerungsverfahren für eine Hubhöhenvorwahl eines Flurförderzeugs mit einem an einem Hubgerüst höhenbeweglich geführten Lastaufnahmemittel, insbesondere einer Lastgabel, wobei eine bestimmte anzufahrende Hubhöhe ausgewählt werden kann, indem in einem ersten Schritt mit einer Bedienvorrichtung das Lastaufnahmemittel in Richtung auf die anzufahrende Hubhöhe bewegt wird, indem das Lastaufnahmemittel angehoben oder abgesenkt wird, und bei Betätigung eines zusätzlichen Schalters die nächste zu erreichende einprogrammierte Hubhöhe ausgewählt wird und an dieser die Hubbewegung automatisch von der Steuerungsvorrichtung gestoppt wird, eine Auswahl zwischen Einlagern oder Auslagern durch ein nachfolgendes kurzzeitiges Betätigen des zusätzlichen Schalters.The object is achieved in that in a control method for a Hubhöhenvorwahl an industrial truck with a height-movably guided on a mast load handling device, in particular a fork, with a certain approaching lifting height can be selected by in a first step with an operating device, the load receiving means in the direction the lifting height to be approached is moved by raising or lowering the load receiving means, and upon actuation of an additional switch, the next programmed lift height to be reached is selected and at which the lifting movement is automatically stopped by the control device, a choice between storage or retrieval by a subsequent short term Press the additional switch.
Dadurch kann auf einfache sowie intuitive Art und Weise, ohne dass eine Bildschirmanzeige genutzt oder der Blick eines Benutzers auf Schaltelemente gerichtet werden muss, nicht nur eine Auswahl einer bestimmten Hubhöhe erfolgen, sondern auch eingestellt werden, ob ein Einlagern oder ein Auslagern erfolgen soll. Die Hubhöhe kann dabei dadurch bestimmt sein, dass in einer Steuerungsvorrichtung die anzufahrenden Hubhöhen einprogrammiert werden können. Es ist jedoch auch möglich, dass die Hubhöhen auf eine sonstige Art und Weise festgelegt werden oder als Daten übertragen werden auf das Flurförderzeug. Dabei kann bei einer Bedienvorrichtung, die einen zusätzlichen Schalter, beispielsweise an der Bedienvorrichtung selbst oder in dessen unmittelbarer Nähe, aufweist, durch Betätigung des Schalters ausgewählt werden, dass die nächste erreichte, einprogrammiert oder auf sonstige Weise bestimmte Hubhöhe ausgewählt werden soll und bei dieser Hubhöhe gestoppt wird. Dies ist sowohl beim Anfahren einer ausgewählten Hubhöhe von oben durch Absenken, als auch beim Anfahren einer ausgewählten Hubhöhe von unten durch Anheben des Lastaufnahmemittels möglich. Unmittelbar anschließend an diese Auswahl kann durch kurzzeitiges Betätigen des Schalters eine Auswahl zwischen Einlagern oder Auslagern getroffen werden. Da die Bedienvorrichtungen im Regelfall elektrische Signalgeber sind, die die übliche Arbeitshydraulik der Hubvorrichtung über elektromagnetisch betätigte Hydraulikventile und eine Steuerung ansteuern, lässt sich die vorgeschlagene Lösung kostengünstig und einfach allein durch Software umsetzen. In einer Programmsteuerung kann bewertet werden, ob eine kurzzeitige und schnelle Betätigung der Bedienvorrichtung unter bestimmte zeitliche Grenzwerte fällt und es kann in diesem Fall kein Signal an die Hydraulikventile weitergegeben werden, sondern allein die beschriebene Auswahl erfolgen.This can be done in a simple and intuitive way and manner, without having to use a screen display or the user's gaze to be directed to switching elements, not only a selection of a certain lifting height done, but also set whether a storage or outsourcing should be made. The lifting height can be determined by the fact that in a control device to be approached lifting heights can be programmed. However, it is also possible that the lifting heights are set in a different manner or transmitted as data on the truck. In this case, in the case of an operating device which has an additional switch, for example on the operating device itself or in its immediate vicinity, it can be selected by actuating the switch that the next reached, programmed or otherwise determined lifting height should be selected and at this lifting height is stopped. This is possible both when approaching a selected lifting height from above by lowering, and when starting a selected lifting height from below by lifting the lifting device. Immediately following this selection, a short-term actuation of the switch can make a selection between storage or retrieval. Since the operating devices are usually electrical signal transmitters which control the usual working hydraulics of the lifting device via electromagnetically actuated hydraulic valves and a controller, the proposed solution can be implemented cost-effectively and simply by software alone. In a program control can be assessed whether a short-term and rapid operation of the operating device falls below certain time limits and in this case no signal can be passed to the hydraulic valves, but only the described selection done.
Die Aufgabe wird auch dadurch gelöst, dass bei einem Steuerungsverfahren für eine Hubhöhenvorwahl eines Flurförderzeugs mit einem an einem Hubgerüst höhenbeweglich geführten Lastaufnahmemittel, insbesondere einer Lastgabel, wobei eine bestimmte anzufahrende Hubhöhe ausgewählt werden kann, indem in einem ersten Schritt mit einer Bedienvorrichtung das Lastaufnahmemittel in Richtung auf die anzufahrende Hubhöhe bewegt wird, indem das Lastaufnahmemittel angehoben oder abgesenkt wird, und bei Betätigung eines zusätzlichen Schalters, die nächste zu erreichende einprogrammierte Hubhöhe ausgewählt wird und an dieser die Hubbewegung automatisch von der Steuerungsvorrichtung gestoppt wird, durch die Betätigung des zusätzlichen Schalters zugleich eine Auswahl zwischen Einlagern oder Auslagern erfolgt, abhängig von der Anzahl kurzzeitiger Betätigungen des Schalters.The object is also achieved in that in a control method for a Hubhöhenvorwahl an industrial truck with a height-movably guided to a mast load handling device, in particular a fork, with a certain approaching lifting height can be selected by the load receiving means in a first step with an operating device is moved to the approaching lifting height by the load receiving means is raised or lowered, and upon actuation of an additional switch, the next to be reached programmed stroke height is selected and at which the lifting movement is automatically stopped by the control device, by the operation of the additional switch at the same time Selection between warehousing or swapping takes place, depending on the number of short-term operations of the switch.
Dieses Steuerungsverfahren weist die bereits zuvor geschilderten Vorteile auf. Insbesondere kann in einem einzigen Arbeitsschritt sowohl die Auswahl der anzufahrenden Hubhöhe erfolgen, als auch die Auswahl zwischen Einlagern bzw. Auslagern. Dadurch wird eine schnelle Bedienung des Flurförderzeugs möglich. Die Anzahl kurzzeitiger Betätigung des Schalters kann sich dabei insbesondere darauf beziehen, dass der Schalter einmal kurz betätigt wird oder innerhalb einer bestimmten festgelegten Zeitspanne zweimal kurz betätigt wird. Jeweils eine der beiden Betätigungsarten wird dabei dem Einlagern zugeordnet und die andere dem Auslagern.This control method has the advantages already described above. In particular, both the selection of the lifting height to be approached can take place in a single work step, as can the selection between storage and retrieval. This makes a quick operation of the truck possible. The number of short-term actuation of the switch may relate in particular to the fact that the switch is operated once briefly or is operated twice briefly within a certain predetermined period of time. In each case one of the two types of actuation is assigned to the storage and the other the outsourcing.
In einer Ausbildung des Verfahrens wird durch einmaliges Betätigen ein Auslagern ausgewählt.In one embodiment of the method, a retrieval is selected by a single actuation.
In einer weiteren Ausgestaltung des Verfahrens wird durch zweimaliges Betätigen ein Einlagern ausgewählt.In a further embodiment of the method, a storage is selected by pressing twice.
Vorteilhaft wird durch dreimaliges Betätigen eine Auswahl des Einlagern oder Auslagerns aufgehoben.Advantageously, a selection of storage or removal is canceled by pressing three times.
Durch diese Aufhebung einer Vorauswahl lässt sich in jedem Fall ein definierter Zustand einstellen.By canceling a preselection, a defined state can always be set.
Durch Stellen der Bedienvorrichtung in die neutrale Stellung und erneute Betätigung kann ein Hubvorgang bzw. ein Absenken fortgesetzt werden.By placing the operating device in the neutral position and re-actuation, a lifting operation or a lowering can be continued.
Es kann eine Mindestverweildauer in der neutralen Stellung erforderlich sein.A minimum residence time in the neutral position may be required.
Dies ermöglicht eine Fortsetzung des Hubvorgangs, wenn beispielsweise eine Auswahl einer Hubhöhe fehlerhaft erfolgte.This allows the lifting operation to continue if, for example, a selection of a lifting height was made incorrectly.
Weitere Vorteile und Einzelheiten der Erfindung werden anhand des in der schematischen Figur dargestellten Ausführungsbeispiels näher erläutert. Hierbei zeigt die Figur einen Schubmaststapler 1 als Ausführungsbeispiel für ein Flurförderzeug 2. Der Schubmaststapler 1 weist als Lastaufnahmemittel 3 eine Lastgabel 4 auf, die an einem Hubgerüst 10, das zugleich als Schubmast 8 verschiebbar ist, höhenbeweglich geführt ist. Unterhalb eines Fahrerschutzdaches 5 in einen Bedienstand des Schubmaststaplers 1 befindet sich eine Bedienvorrichtung 6 in Form eines Joysticks 7, mit der neben anderen Funktionen auch die Hubfunktion der Lastgabel 4 bedient werden kann. Die Bedienvorrichtung 6 weist einen zusätzlichen Schalter 9 auf, mit dem das Anfahren der nächsten erreichten einprogrammierten Hubhöhe ausgewählt werden kann und mit dem eine Auswahl zwischen einem Einlagern oder Auslagern erfolgen kann, bei dem zu einer einprogrammierten Hubhöhe unterschiedliche Höhen angefahren werden müssen, die um einen bestimmten Betrag, etwa 15 cm, voneinander abweichen wie in der Figur durch den Doppelpfeil dargestellt.Further advantages and details of the invention will be explained in more detail with reference to the embodiment shown in the schematic figure. The figure shows a reach truck 1 as an exemplary embodiment of an industrial truck 2. The reach truck 1 has a load fork 3 as a fork 4, which is guided vertically movable on a
Die einprogrammiert Hubhöhen entsprechen dabei beispielsweise den Höhen von Regalfächern R1 bis R6 eines Hochregals 10. Wenn, wie in dem dargestellten Beispiel das Regalfach R5 angefahren werden soll, so betätigt ein Fahrer die Bedienvorrichtung 6 so, dass die Lastgabel 4 sich an dem Hubgerüst 10 bzw. Schubmast 8 anhebt oder auch abhängig von der Ausgangsposition der Lastgabel 4 absenkt. Wenn kurz vor Erreichen der Höhe des Regalfachs R5 der zusätzliche Schalter 9 betätigt wird, so wird die zugehörige einprogrammiert Hubhöhe ausgewählt.The programmed lift heights correspond, for example, to the heights of shelves R1 to R6 of a
Durch eine unmittelbar danach folgende schnelle zweimalige Betätigung des zusätzlichen Schalters 9 kann dann beispielsweise ein Einlagern ausgewählt werden, bei dem die Lastgabel 4 um ein solches Maß zusätzlich angehoben wird, dass auch bei einer aufgenommenen Palette ein Hineinfahren der Lastgabel 4 in das Regalfach R5 möglich ist. Die Hubbewegung bzw. Absenkbewegung wird dann automatisch bei der einprogrammierten und ausgewählten Hubhöhe für ein Einlagern, die dem Regalfach R5 entspricht gestoppt.By an immediate subsequent rapid two-time operation of the additional switch 9 can then be selected, for example, a storage in which the fork 4 is further increased by such a degree that even with a recorded pallet a driving in of the fork 4 in the shelf R5 is possible , The lifting movement or lowering movement is then automatically stopped at the programmed and selected lifting height for a storage corresponding to the shelf R5.
Ebenso ist beispielsweise durch einmaliges kurzes Betätigen des zusätzlichen Schalters 9 möglich, ein Auslagern auszuwählen, bei dem die Hubbewegung automatisch bei der einprogrammierten und etwas geringeren Hubhöhe für das Regalfach R5 gestoppt wird, bei der es möglich ist, eine in dem Regalfach R5 aufliegende Palette aufzunehmen.Likewise, for example, by a single short pressing the additional switch 9 is possible to select an outsourcing, in which the lifting movement is automatically stopped at the programmed and slightly lower lifting height for the shelf R5, in which it is possible to record a resting in the shelf R5 range ,
In einer weiteren alternativen Ausführungsform, durch die die Aufgabe ebenfalls gelöst wird, wird kurz vor Erreichen der Höhe des Regalfachs R5 der zusätzliche Schalter 9 betätigt, um die zugehörige einprogrammierte Hubhöhe auszuwählen. Dabei erfolgt jedoch gleichzeitig bereits eine Auswahl zwischen dem Einlagern oder dem Auslagern, indem die Bedienperson sich zwischen zwei Betätigungsweisen des zusätzlichen Schalters 9 entscheidet. Beispielsweise kann durch eine schnelle zweimalige Betätigung des zusätzlichen Schalters 9 die nächste zu erreichende Hubhöhe und zugleich ein Einlagern ausgewählt werden, bei dem die Lastgabel 4 um ein solches Maß höher angehalten wird, dass auch bei einer aufgenommenen Palette ein Hineinfahren der Lastgabel 4 in das Regalfach R5 möglich ist.In a further alternative embodiment, by which the object is also achieved, the additional switch 9 is actuated shortly before reaching the height of the shelf R5 to select the associated programmed stroke height. At the same time, however, a selection already takes place between storage or retrieval by the operator deciding between two actuation modes of the additional switch 9. For example, by a quick two-time operation of the additional switch 9, the next to be reached lifting height and a storage are selected, in which the fork 4 is stopped higher by such a degree that even with a recorded pallet, a driving in of the fork 4 in the shelf R5 is possible.
Ebenso ist beispielsweise durch einmaliges kurzes Betätigen des zusätzlichen Schalters 9 möglich, zusammen mit der anzufangen Höhe des Regales R5 ein Auslagern auszuwählen, bei dem die Hubbewegung bzw. Absenkbewegung automatisch bei der einprogrammierten und etwas geringeren Hubhöhe für das Regalfach R5 gestoppt wird, bei der es möglich ist, eine in dem Regalfach R5 aufliegende Palette aufzunehmen.Likewise, for example, by a single short pressing the additional switch 9 is possible to select along with the beginning of the height of the shelf R5 outsourcing, in which the lifting or lowering movement is automatically stopped at the programmed and slightly lower lifting height for the shelf R5, in which it it is possible to record a resting in the shelf R5 range.
