Abstract

The stacking hoist comprises a main load platform which is driven outwards by a first drive system. Several other load surfaces are arranged in the main load surface with a telescopic action to extend the reach of the hoist. A second drive system operates at least the inner load surfaces to lift using scissors support arms. The telescopic drive is via a conventional drive while the scissors drive is via a cable drive. The operator is able to reach stacking shelves by a combination of lateral telescopic drive and the hoist drive.

Description

Die Erfindung betrifft ein Lastaufnahmemittel zur doppeltiefen Ein- beziehungsweise Auslagerung von palettierten Ladeeinheiten, in einem Hochregallager, entsprechend dem Oberbegriff des ersten Patentanspruches.
Zum Ein- beziehungsweise Auslagern von palettierten Ladeeinheiten in einem Hochregallager sind Teleskopgabeln üblich.
Die Teleskopgabeln zur doppeltiefen Lagerung von Ladeeinheiten werden je nach Anwendungsfall mit drei beziehungsweise vier ausfahrenden Tischen ausgeführt. Der Antrieb der Teleskopgabel erfolgt dabei entweder über eine Zahnstange oder über eine sogenannte Kombikette am untersten Tisch. Die Kraftübertragung und Bewegungskopplung der anderen Tische erfolgt dabei über sogenannte Koppelketten oder Zahnräder und Zahnstangen. Diese Konstruktionen übertragen die Kräfte auf die oberen Tische und lassen dadurch alle Tische proportional zueinander ausfahren, das heißt, daß sich der gesamte Ausfahrweg des Teleskoptisches gleichmäßig auf alle Tische verteilt.
Die bekannten Bauarten von Teleskoptischen für die doppeltiefe Lagerung von Ladeeinheiten haben funktionsbedingt folgende Nachteile: Beim Verschieben des unteren Tisches werden alle oberen Tische gleichmäßig ausgefahren. Daraus resultiert, daß bei jeder Ein- beziehungsweise Auslagerung von der vorderen Position im Regal alle Teleskoptische in einen Freiraum unter der Ladeeinheit einfahren müssen. Deswegen müssen die palettierten Ladeeinheiten bei der doppeltiefen Lagerung auf sogenannte Tiefenriegel aufgeständert werden, da der Einfahrbereich bei den gebräuchlichen Ladehilfsmitteln (Paletten) zu niedrig ist. Durch die Aufständerung der Ladeeinheiten im Regal erhöhen sich die Investitionskosten für den Regalstahlbau in einem Hochregallager erheblich.The invention relates to a load handling device for double-deep storage or retrieval of palletized loading units in a high-bay warehouse, according to the preamble of the first claim.
Telescopic forks are common for storing and retrieving palletized loading units in a high-bay warehouse.
Depending on the application, the telescopic forks for double-deep storage of loading units are designed with three or four extending tables. The telescopic fork is driven either by a rack or by a so-called combination chain at the lowest table. The power transmission and movement coupling of the other tables takes place via so-called coupling chains or gear wheels and racks. These constructions transmit the forces to the upper tables and allow all tables to extend proportionally to each other, which means that the entire extension path of the telescopic table is evenly distributed over all tables.
The known types of telescopic tables for the double-deep storage of loading units have the following disadvantages due to their function: When moving the lower table, all upper tables are extended evenly. As a result, all telescopic tables have to move into a free space under the loading unit each time they are stored or removed from the front position on the shelf. For this reason, the palletized loading units for double-deep storage must be raised to so-called depth bolts, since the entry area for the usual loading aids (pallets) is too low. The elevation of the loading units on the shelf increases the investment costs for the steel construction in a high-bay warehouse considerably.

Aus EP 0 655 048 B1 ist eine Vorrichtung bekannt, die auf einem Grundrahmen angeordnet ist und quer zu diesem von einer auf die andere Seite bewegbar ist. Auf diesem Wagenbereich sind ein oder mehrere Antriebe angeordnet. Diese Antriebe fahren mit dem Wagenbereich aus. Damit ist eine Energieversorgung zu diesem Wagenbereich nötig, was konstruktiv aufwendig ist.
Aus FR-A-2709745 ist ein Lastaufnahmemittel doppeltiefen Ein- bzw. Auslagerung von palettierten Ladeeinheiten, bestehend aus einer Teleskopgabel mit mehreren Teleskoparmen (2, 3, 4, 5) bekannt, welche aus ausfahrbaren Tischen und einem Untertisch (1) als Rahmen bestehen, wobei wahlweise alle Tische (2-5) oder nur die beiden oberen Tische (4, 5) ausfahrbar sind, welches durch die Kopplung zweier Antriebe (30, 35) erreicht wird, welche auf dem Untertisch (1) angeordnet sind, von denen der erste Antrieb (35) auf einen oder mehrere Tische (2, 3) wirkt und der zweite Antrieb (30) über einen seperaten Antriebsstrang (31, 34, 23, 29, 26, 19, 15) abhängt vom ersten Antrieb (35) auf die oberen Tische (4, 5) wirkt. Bei dieser Vorrichtung wird aber das Ausfahren der Tische im Zusammenhang mit den Antrieben anders vorgenommen als das mit der vorliegenden Erfindung der Fall ist, wobei beide Antriebe bewegt werden müssen, um die Tische auszufahren.A device is known from EP 0 655 048 B1, which is arranged on a base frame and can be moved transversely to it from one side to the other. One or more drives are arranged on this carriage area. These drives extend with the car area. This requires an energy supply to this car area, which is structurally complex.
From FR-A-2709745 a load handling device double-deep storage or retrieval of palletized loading units, consisting of a telescopic fork with several telescopic arms (2, 3, 4, 5) is known, which consist of extendable tables and a lower table (1) as a frame , with either all tables (2-5) or only the two upper tables (4, 5) being extendable, which is achieved by coupling two drives (30, 35) which are arranged on the lower table (1), of which the first drive (35) acts on one or more tables (2, 3) and the second drive (30) via a separate drive train (31, 34, 23, 29, 26, 19, 15) depends on the first drive (35) acts on the upper tables (4, 5). In this device, however, the extension of the tables in connection with the drives is carried out differently than is the case with the present invention, both drives having to be moved in order to extend the tables.

Es ist daher Aufgabe der Erfindung, ein Lastaufnahmemittel zur doppeltiefen Einlagerung beziehungsweise Auslagerung von palettierten Ladeeinheiten zu entwickeln, bei dem nur ein Antrieb aktiv sein muss, um die Tische auszufahren.It is therefore an object of the invention to provide a lifting device for double depths Storage or retrieval of palletized loading units to develop in which only one drive has to be active to extend the tables.

Diese Aufgabe wird durch eine Vorrichtung mit den kennzeichnenden Merkmalen des ersten Patentanspruches gelöst.
Die Unteransprüche geben vorteilhafte Ausführungen der Erfindung wieder. Wesentlicher Bestandteil der Erfindung sind zwei Teleskoparme, welche wiederum aus mehreren, vorzugsweise je drei oder vier ausfahrbaren Tischen und einem Untertisch als Grundrahmen zur Montage, zum Beispiel auf einen Hubwagen eines Regalbediengerätes, bestehen.
Der Antrieb des Lastaufnahmemittels, welches als Gabel ausgebildet ist, erfolgt über zwei Antriebe. Der erste Antrieb dient dazu, den untersten Tisch zum Beispiel über Zahnräder und eine Zahnstange, welche an diesem befestigt ist, wahlweise zur linken oder zur rechten Seite auszufahren. Denkbar ist auch ein Antrieb über eine Kombikette mit zwei versetzten Kettenenden, welche an Festpunkten am untersten ausfahrbaren Tisch befestigt sind. Bei einer Teleskopgabel mit vier Tischen wird die Bewegung des zweiten Tisches von unten mit der Bewegung des untersten Tisches zum Beispiel über eine Koppelkette mit Festpunkten gekoppelt. Der zweite Antrieb kann unabhängig vom ersten Antrieb den zweiten Tisch von oben über die beiden versetzten Enden einer Kette, welche über die unteren Tische zum Kettenrad auf den Untertisch geführt werden, ebenfalls wahlweise nach rechts oder links ausfahren.
Die beiden Kettenenden sind jeweils an einem Festpunkt am zweiten Tisch von oben befestigt. Die Bewegung des obersten Tisches wird ebenfalls zum Beispiel über eine Koppelkette mit der Bewegung des zweiten Tisches von oben gekoppelt.This object is achieved by a device with the characterizing features of the first claim.
The subclaims represent advantageous embodiments of the invention. An essential part of the invention are two telescopic arms, which in turn consist of several, preferably three or four extendable tables and a lower table as a base frame for mounting, for example on a pallet truck of a storage and retrieval unit.
The load suspension device, which is designed as a fork, is driven by two drives. The first drive is used to extend the lowest table either to the left or to the right, for example via gear wheels and a rack that is attached to it. A drive via a combination chain with two offset chain ends, which are attached to fixed points on the lowest extendable table, is also conceivable. In the case of a telescopic fork with four tables, the movement of the second table from below is coupled with the movement of the lowest table, for example via a coupling chain with fixed points. Independently of the first drive, the second drive can also extend the second table from above via the two staggered ends of a chain, which are led via the lower tables to the sprocket on the lower table, either to the right or left.
The two chain ends are each attached to the second table from above at a fixed point. The movement of the top table is also coupled to the movement of the second table from above, for example via a coupling chain.

Die Position der Tische beim Anfahren in der vorderen und der hinteren Position im Regal können durch eine Wegmessung, einen Endschalter oder andere geeignete Einrichtungen an den einzelnen Tischen überwacht werden.The position of the tables in the front and rear positions when moving off on the shelf can be measured by a path, a limit switch or other suitable facilities are monitored at the individual tables become.

Die erfindungsgemäße Vorrichtung hat den Vorteil, daß für die Aufnahme beziehungsweise Abgabe der Last nur die oberen, schmalen Gabelquerschnitte unter die Last einfahren müssen, wodurch ermöglicht wird, daß die palettierte Ladeeinheit direkt auf den Plattenträger abgestellt werden kann und nicht mehr aufgeständert werden müssen. Weiterhin entfällt die bewegliche Energieversorgung zu einem Wagenbereich, wodurch sich die Konstruktion vereinfacht und die Inverstitionskosten verringert werden. Nachfolgend soll die Erfindung an zehn Figuren und einem Ausführungsbeispiel näher erläutert werden. Die Figuren zeigen:

The device according to the invention has the advantage that only the upper, narrow cross-sections of the fork have to be inserted under the load to receive or deliver the load, which enables the palletized loading unit to be placed directly on the plate carrier and no longer has to be raised. Furthermore, there is no need for a mobile power supply to a car area, which simplifies the construction and reduces the investment costs. The invention will be explained in more detail below using ten figures and an exemplary embodiment. The figures show:

Die in Figur 1 dargestellte Teleskopgabel besteht aus drei ausfahrenden Tischen 10, 20, 30a, die auf einem Untertisch 40 als Grundrahmen zur Montage auf einem Hubwagen 50 eines Regalbediengerätes angeordnet sind. Zum Antrieb sind zwei Antriebe A1 und A2 vorgesehen, wobei A1 den ersten Antrieb 100 und A2 den zweiten Antrieb 200 darstellt. Beide Antriebe A1 und A2 besitzen eine Bremse 101 und 201. Die Kraftübertragung auf den Antriebsstrang von A1 erfolgt über angetriebene Zahnräder 110 und Zahnstangen 120. Die Kraftübertragung bei dem Antriebsstrang von A2 erfolgt über Kettenräder 210 und eine Kette mit zwei versetzten Enden 220 und Festpunkt 230 am zweiten Tisch von oben 20.
Zum Handling der hinteren Ladeeinheiten 1 im Regalfach werden alle drei Tische 10, 20, 30a über den ersten Antrieb 100 ausgefahren. Der zweite Antrieb 200 ist dabei über die Motorbremse 201 blockiert, so daß das Antriebskettenrad 210 für die Kette 220 als Festpunkt auf dem Grundrahmen 40 wirkt und dadurch die Bewegung der oberen beiden Tische 10, 20 mit der Bewegung des untersten Tisches 30a koppelt. Die Figur 2 zeigt die erfindungsgemäße Vorrichtung in der vorderen Position im Regal mit der Ladeeinheit 1, wobei nur die oberen beiden Tische 10, 20 separat ausgefahren wurden. Das geschieht, indem die beiden oberen Tische 10, 20 über den zweiten Antrieb 200 in den Gabelhohlraum des Ladehilfsmittels 2 ausfahren. Die Bewegung des untersten Tisches 30a ist dabei über die Motorbremse 101 des ersten Antriebes 100 blockiert. Die Figuren 3 und 4 zeigen Funktionsschemata der Antriebssysteme A1 und A2 der Figuren 1 und 2. Bei der Teleskopgabel mit vier Tischen 10, 20, 30b, 30a, wie sie in den Figuren 6 bis 10 dargestellt ist, wird die Bewegung des zweiten Tischen von unten 30b mit der Bewegung des untersten Tisches 30a über eine Koppelkette mit Festpunkt gekoppelt. Der zweite Antrieb 200 kann unabhängig vom ersten Antrieb 100 den zweiten Tisch von oben 20 über die beiden versetzten Enden der Kette 220, welche über die unteren Tische zum Kettenrad 210 auf den Untertisch geführt wird, ebenfalls wahlweise zur rechten oder zur linken Seite gefahren werden. Die beiden Kettenenden sind jeweils an einen Festpunkt 230 am zweiten Tisch von oben 20 befestigt. Die Bewegung des obersten Tisches 10 wird ebenfalls über eine Koppelkette mit der Bewegung des zweiten Tisches von oben 20 gekoppelt. Zum Handling der vorderen Ladeeinheit 1 im Regalfach werden die oberen beiden Tische 10, 20 über den zweiten Antrieb 200 in den Gabelhohlraum des Ladehilfsmittels 2 ausgefahren (Figur 7). Die Bewegung der beiden unteren Tische 30a, 30b ist dabei über die Motorbremse 101 des ersten Antriebes 100 blockiert. Zum Handling der hinteren Ladeeinheit 1 im Regalfach (Figur 6) werden alle vier Tische 10, 20, 30b, 30a über beide Antriebe 100, 200 ausgefahren. Der erste 100 und der zweite Antrieb 200 können dabei synchron oder hintereinander angesteuert werden, um alle Tische auszufahren. Das Funktionsschema der Figuren 6 und 7 ist den Figuren 8 und 9 zu entnehmen. The telescopic fork shown in Figure 1 consists of three extending tables 10, 20, 30a, which are arranged on a lower table 40 as a base frame for mounting on a pallet truck 50 of a storage and retrieval unit. Two drives A1 and A2 are provided for the drive, A1 representing the first drive 100 and A2 the second drive 200. Both drives A1 and A2 have a brake 101 and 201. The power transmission to the drive train from A1 takes place via driven gear wheels 110 and racks 120. The power transmission in the drive train from A2 takes place via chain wheels 210 and a chain with two offset ends 220 and fixed point 230 at the second table from above 20.
For handling the rear loading units 1 in the shelf compartment, all three tables 10, 20, 30a are extended via the first drive 100. The second drive 200 is blocked by the motor brake 201 so that the drive sprocket 210 for the chain 220 acts as a fixed point on the base frame 40 and thereby couples the movement of the upper two tables 10, 20 with the movement of the lower table 30a. FIG. 2 shows the device according to the invention in the front position on the shelf with the loading unit 1, only the upper two tables 10, 20 being moved out separately. This takes place in that the two upper tables 10, 20 extend into the fork cavity of the loading aid 2 via the second drive 200. The movement of the lowest table 30a is blocked by the motor brake 101 of the first drive 100. Figures 3 and 4 show functional diagrams of the drive systems A1 and A2 of Figures 1 and 2. In the telescopic fork with four tables 10, 20, 30b, 30a, as shown in Figures 6 to 10, the movement of the second table of below 30b coupled with the movement of the lowest table 30a via a coupling chain with a fixed point. Independently of the first drive 100, the second drive 200 can also optionally move the second table from above 20 via the two offset ends of the chain 220, which is led via the lower tables to the chain wheel 210 onto the lower table, either to the right or to the left. The two chain ends are each attached to a fixed point 230 on the second table from above 20. The movement of the top table 10 is also coupled to the movement of the second table from above 20 via a coupling chain. To handle the front loading unit 1 in the shelf compartment, the upper two tables 10, 20 are extended via the second drive 200 into the fork cavity of the loading aid 2 (FIG. 7). The movement of the two lower tables 30a, 30b is blocked by the motor brake 101 of the first drive 100. To handle the rear loading unit 1 in the shelf compartment (FIG. 6), all four tables 10, 20, 30b, 30a are extended via both drives 100, 200. The first 100 and the second drive 200 can be controlled synchronously or in succession in order to extend all the tables. The functional diagram of FIGS. 6 and 7 can be seen in FIGS. 8 and 9.

Load lifting means for the double-depth storage and retrieval of palletised unit loads in a high-level rack-type storage system, comprising a telescopic fork provided with a plurality of telescopic arms, which fork comprises extendable platens (10, 20, 30a, 30b) and a lower platen (40) as a frame, for example for assembly on a lift truck of a rack operating appliance, all of the platens (10, 20, 30a, 30b) or only the two upper platens (10, 20) being selectively extendable, this being achieved by the linking of two drives (100, 200), which are disposed on the lower platen (40), the first drive (100) of which acts on one or more of the platens (30a, 30b), and the second drive (200) of which acts on the two upper platens (10, 20) independently of the first drive (100) via a separate working line (210, 220, 230), characterised in that the control device for reaching the front position in the rack only extends the two upper platens (10, 20) via the second drive (200), the lowermost platen (30a) stops in the central position on the lift truck (50) by locking the first drive (100), and, to reach the rear position in the rack, said control device extends all of the platens (10, 20, 30a) via the first drive (100) and links the movement of the two upper platens (10, 20) to the movement of the lower platen (30a) by locking the second drive (200).
  2. Load lifting means according to claim 1, characterised in that the control device for reaching the front position in the rack only extends the two upper platens (10, 20) via the second drive (200), and the two lowermost platens (30a, 30b) are retained in the central position of the lift truck by locking the first drive (100), and both drives (100, 200) are synchronously actuated to reach the rear position in the rack and thereby extend all of the platens (10, 20, 30a, 30b) uniformly.
  3. Load lifting means according to claims 1 and 2, characterised in that the control device for reaching the front position in the rack only extends the two upper platens (10, 20) via the second drive (200) and retains the two lowermost platens (30a, 30b) in the central position of the lift truck (50) by locking the first drive (100), and both drives (100, 200) are actuated successively to reach the rear position in the rack and thereby extend the two lower platens (30a, 30b) and the two upper platens (10, 20) in a time-staggered manner.
  4. Load lifting means according to claims 1 to 3, characterised in that the relative lift of the load lifting means to raise or respectively to deposit the unit loads (1) in the rack is effected via a separate lifting mechanism, for example the lift truck of a rack operating appliance.
  5. Load lifting means according to claims 1 to 4, characterised in that the position of the platens (10, 20) is monitored by a travel measuring device when the front and rear positions in the rack are reached.
