Abstract

The lifting platform forms part of the transportation and shelf loading equipment for the storage unit. The platform is required to move up rapidly to the load, take the load up gently, and then complete the lift by again moving rapidly. Brackets (4) support the platform (2) and have rollers (7) which move in the closed cam tracks (6). The cam tracks are machined in plates (3) attached to the side frames (1) of the loading equipment. The tracks have steep-shallow-steep segments to provide the desired lifting action. USE/ADVANTAGE - Platform is stable and securely held in closed cam track. Load is raised without shock in minimum time.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Handha­ ben von Transport- und Lagereinheiten, insbesondere in Hoch­ regal-Blocklager-Systemen als schienengebundenenes Fahrzeug mit einem Fahrzeugrahmen sowie einer heb- und senkbaren Hub­ plattform, ausgerüstet mit das Heben und Senken bewirkenden Führungselementen, die über Hub- bzw. Senkkulissen geführt sind, wobei der Fahrzeugrahmen beim Heben bzw. Senken syn­ chron in entgegengesetzter Richtung relativ zur Hubplatt­ form verfahrbar ist. Eine derartige Vorrichtung ist nach DE 32 13 983 C2 bekannt.The invention relates to a device for handling ben of transport and storage units, especially in high Shelf block storage systems as a rail-bound vehicle with a vehicle frame and a lifting and lowering stroke platform equipped with lifting and lowering Guide elements that are guided over lifting or lowering links are, the vehicle frame when lifting or lowering syn chron in the opposite direction relative to the hub plate form is movable. Such a device is after DE 32 13 983 C2 known.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Einrichtung zu verbessern.The invention has for its object the generic Improve facility.

Dies wird dadurch erreicht, daß die Hub- und Senkkulissen an seitlichen Fahrgestellen angeordnet sind und Kurven mit un­ gleichmäßigen Steigungen aufweisen, wobei die Kurven derart ausgebildet sind, daß die Hubplattform in einer schnellen Leerhubphase die Höhe zwischen der untersten Stellung und der Lastaufnahmestellung überwindet, in einer Übergangsphase zur Erzielung eines möglichst geringen Stoßes nach oben be­ wegt wird und nach Übernahme der Last in der Lasthubphase wieder schneller wird. Solcherart werden klar definierte Leer- oder Lastbereiche schnell durchfahren und somit die Hubzeit minimiert, während die Übergangsphase, d. h., die Phase der Übernahme der Hubpalette mit geringer Steigung an­ gefahren wird, um so Stöße und undefinierte Reibungsverhält­ nisse zu vermeiden. This is achieved in that the lifting and lowering links side chassis are arranged and curves with un have uniform slopes, the curves being such are trained that the lifting platform in a fast Idle stroke phase the height between the lowest position and overcome the load suspension position in a transition phase to achieve the lowest possible impact is moved and after taking over the load in the load lifting phase gets faster again. Such are clearly defined Drive through empty or load areas quickly and thus the Stroke time minimized during the transition phase, i. i.e., the Phase of taking over the lifting range with a slight incline is driven, so shocks and undefined friction ratio to avoid nisse.  

Nach einem besonders wichtigen Merkmal der Erfindung weisen die Hub- und Senkkulissen innerhalb einer Hub- und Senkebene Führungsbahnen mit geschlossener Kontur auf, in denen Lauf­ rollen oder Kulissensteine der das Heben und Senken bewir­ kenden Führungselemente angeordnet sind. Mit dieser Maßnahme wird sicher verhindert, daß die Plattform sich abheben kann.According to a particularly important feature of the invention the lifting and lowering links within a lifting and lowering level Guideways with a closed contour, in which run roll or backdrop stones that cause the lifting and lowering kenden guide elements are arranged. With this measure will surely prevent the platform from lifting off.

Nach einem anderen Merkmal der Erfindung sind neben den in den Kulissen geführten Rollen Führungsscheiben angebracht, die sich an den Seitenflächen der Kulissen abstützen. Auf diese Weise wird eine Drehung der Plattform um die Hochachse vermieden.According to another feature of the invention, in addition to those in castors mounted on the scenes, which are supported on the side surfaces of the scenery. On this way the platform rotates about the vertical axis avoided.

Die Erfindung ist in einem Ausführungsbeispiel beschrieben und dargestellt. Es zeigtThe invention is described in one embodiment and shown. It shows

Fig. 1 eine schematische Darstellung der Vorrichtung in der Seitenansicht, Fig. 1 is a schematic representation of the apparatus in side view,

Fig. 2 eine schematische Darstellung des Kurvenab­ laufes. Fig. 2 is a schematic representation of the curvature.

Fig. 1 zeigt eine an seitlichen Fahrgestellen 1 des Fahrzeug­ rahmens fest angeordnete Hub-Senk-Kulisse 3, in deren Füh­ rungsbahnen 6 an Führungselementen 4 sich drehbar angeordnete Laufrollen 7 abwälzen. Die Führungselemente 4 sind fest mit der Hubplattform 2 verbunden. Aus Fig. 2 ist die Kurve 5 der aus Fig. 1 ersichtlichen Führungsbahn 6 näher zu ersehen. In der Einsatzphase der Hubplattform 2 zum Aufnehmen oder Absetzen eines Gegenstandes gleitet die Laufrolle 7 zunächst im Freihub auf ein Kurventeil a mit großer Steigung auf. Dann geht die Kurve in der Übergabephase in eine geringe Steigung b über und hebt in einer Kurvenphase c nach sicherem Auf­ greifen des Gegenstandes schnell in die Endlage an. Fig. 1 shows a on the side chassis 1 of the vehicle frame fixed lift-lower link 3 , in the Füh approximately 6 on guide elements 4 rotatably arranged rollers 7 roll. The guide elements 4 are firmly connected to the lifting platform 2 . The curve 5 of the guideway 6 shown in FIG. 1 can be seen in more detail from FIG. 2. In the use phase of the lifting platform 2 for picking up or setting down an object, the roller 7 initially slides onto a curve part a with a large slope in the free stroke. Then the curve in the handover phase changes to a slight slope b and in a curve phase c, after the object has been safely picked up, quickly rises to the end position.
