Abstract

1. An inclined continous conveyor for transport trolleys (2) equipped with a manually-releasable brake, which comprise two wheel-carrying axles (20) with different respective wheel spacings, the conveyor comprising separate tracks (5, 6), mutually displaced in height, for the wheels of a respective axle (3, 4) together with circulating drive chains which engage the transport trolleys (2) laterally, the tracks (5, 6) being prolonged in the form substantially flatly extending inlet and outlet lengths in which the brake is ineffective, characterised in that over the inlet and outlet lengths the drive chains (7) are movable to a limited extent transversely to their circulatory planes and over the inlet length they are guided obliquely from the outside into a position of engagement with the transport trolley (2), and over the outlet length they are led obliquely away outwards from an outer position of engagement of the transport trolley (2).

Description

Die Erfindung betrifft einen Schrägstetigförderer für Transportkarren mit den Merkmalen, die im Oberbegriff des Patentanspruchs 1 genannt sind. Derartige Förderer sind dazu bestimmt, Einkaufswagen in Kaufhäusern zwischen den Etagen zu transportieren, aber auch Gepäckkarren auf Bahnhöfen und Flugplätzen zwischen-mehreren Etagen zu befördern.The invention relates to an inclined conveyor for transport carts with the features that are mentioned in the preamble of claim 1. Such conveyors are designed to transport shopping carts in department stores between floors, but also to transport luggage carts at train stations and airfields between several floors.

Eine bekannte Anlage dieser Gattung ist in der DE-PS 19 19 740 beschrieben und dargestellt; sie ist für Einkaufswagen bestimmt.A known system of this type is described and shown in DE-PS 19 19 740; it is intended for shopping carts.

Die auf Flughäfen und Bahnhöfen den Reisenden zur Verfügung stehenden Gepäcktransportkarren weisen im Gegensatz zu den Einkaufswagen, die frei rollbar sind, aus Sicherheitsgründen eine Bremse auf, die ständig mindestens ein Rad blockiert, solange nicht der Benutzer einen die Bremse lösenden Griff oder dergleichen betätigt. Aus diesem Grunde ist die bekannte Anlage zwar auch für solche gebremsten Karren benutzbar, doch muß der Benutzer die Bremse auch während der Schrägfahrt gelöst halten. Dies ist auch kaum zumutbar, wenn parallel zur Förderstrecke eine Fahrtreppe etwa gleicher Geschwindigkeit'läuft, und zwar insbesondere im Bereich des Ein- und Auslaufs der Karren.In contrast to the shopping trolleys, which can be rolled freely, the luggage trolleys available to travelers at airports and train stations have a brake for safety reasons which constantly blocks at least one wheel as long as the user does not actuate a handle or the like which releases the brake. For this reason, the known system can also be used for such braked carts, but the user must keep the brake released even when driving at an angle. This is also hardly reasonable if there is an escalator parallel to the conveyor line same speed 'runs, especially in the area of the entry and exit of the carts.

Aufgabe der Erfindung ist es, eine Anlage mit den im Oberbegriff des Patentanspruchs 1 genannten Merkmalen zu schaffen, die für sowohl gebremste als auch für ungebremste Karren gleichermaßen bequem benutzbar ist.The object of the invention is to provide a system with the features mentioned in the preamble of claim 1, which is equally convenient for both braked and unbraked carts.

Die Lösung dieser Aufgabe ergibt sich aus dem Patentanspruch 1.The solution to this problem results from patent claim 1.

Analog zu einer Fahrtreppe ist mithin die Schrägförderstrecke um eine Einlauf- und Auslaufstrecke verlängert, in die bzw. aus der die Karren bequem schiebbar sind, wobei bereits die Bremse gelöst oder in anderer, noch zu beschreibender Weise unwirksam gemacht wird.Analogous to an escalator, the inclined conveyor section is therefore extended by an entry and exit section, into or out of which the carts can be easily pushed, with the brake already being released or rendered ineffective in another way to be described.

Besonders bevorzugt ist es, wenn an den Karren selbst nur ganz geringe Umbaumaßnahmen zu treffen sind, um das Unwirksammachen der Bremse zu ermöglichen. Im nachstehend beschriebenen Ausführungsbeispiel wird dies im einzelnen erläutert, wobei auf die beigefügten Zeichnungen bezuggenommen wird.

  • Fig, 1 zeigt in Seitenansicht das Schema der Anlage für Abwärtsförderung,
  • Fig. 2 stellt in Draufsicht die Einlaufstrecke aus Fig. 1 dar,
  • Fig. 3 zeigt gegenüber Fig. 1 stark vergrößert die Ausbildung und Lage der gebremsten Achse des Transportkarrens in der Förderstrecke.
It is particularly preferred if only very small conversion measures have to be taken on the carts themselves in order to make the brake ineffective. In the exemplary embodiment described below, this is explained in detail, reference being made to the accompanying drawings.
  • 1 shows a side view of the diagram of the system for downward conveyance,
  • 2 shows a top view of the inlet section from FIG. 1,
  • Fig. 3 shows compared to Fig. 1 greatly enlarged the design and location of the braked axle of the trolley in the conveyor line.

Zunächst soll unter Bezugnahme auf Fig. 3 erläutert werden, wie gemäß der Erfindung die Bremse eines Rades 4 unwirksam gemacht werden kann. Zwar ist bereits bekannt, das Bremsgestänge mittels mechanisch angreifender Mittel zu lüften, doch hat sich dies als nicht zuverlässig herausgestellt, weil die Bremse unter relativ kräftiger, abwärts wirkender Federvorspannung steht. Wenn daher der Karren nur wenig oder gar nicht beladen ist, wird nicht die Bremse gelüftet, sondern der ganze Karren angehoben.3, how the brake of a wheel 4 can be deactivated according to the invention. Although it is already known to release the brake linkage by means of mechanically engaging means, this has not proven to be reliable because the brake is under a relatively strong, downward spring preload. Therefore, if the cart is little or no load, the brake is not released, but the whole cart is raised.

Daher ist erfindungsgemäß vorgesehen, die übliche einfache Steckachse des Rades 4 durch eine verlängerte Achse 20 zu ersetzen, die nach innen über die Achsgabel 22 hinausragt und dort eine leerlaufende Rolle 24 trägt. Der Durchmesser dieser Rolle ist jedoch etwas kleiner als der des Rades 4, so daß sie im normalen Schubbetriev inaktiv ist und auch die Bremsung nicht beeinflußt. Im Bereich*des Schrägförderers jedoch ist eine um etwas mehr als die halbe Durchmesserdifferenz gegenüber der eigentlichen Laufbahn 6 hochstehende Schiene 26 vorgesehen, auf die die Rolle aufläuft, so daß das gebremste Rad 4 nicht mehr den Boden berühren kann. In der Auslaufstrecke des Schrägförderers senkt sich die Schiene dann wieder bis auf das Niveau des Bodens ab.It is therefore provided according to the invention to replace the usual simple thru axle of the wheel 4 with an extended axle 20 which projects inward beyond the axle fork 22 and carries an idling roller 24 there. However, the diameter of this roller is somewhat smaller than that of the wheel 4, so that it is inactive in normal overrun operation and does not affect braking. In the area * of the inclined conveyor, however, a rail 26, which stands up by a little more than half the diameter difference with respect to the actual track 6, is provided, onto which the roller runs, so that the braked wheel 4 can no longer touch the ground. In the discharge section of the inclined conveyor, the rail then lowers again to the level of the floor.

Auf der der Rolle 24 abgewandten Seite der verlängerten Achse 22 ist ein Anschlagstück 25 befestigt, an dem die Mitnehmernocken 8 der Mitnehmerketten 7 angreifen.On the side of the extended axis 22 facing away from the roller 24, a stop piece 25 is fastened, on which the driver cams 8 of the driver chains 7 engage.

Die Ausbildung und Anordnung der Laufbahnen 5 und 6 für die nichtgebremsten Räder 3 des Karrens 2 unterscheidet sich nur insoweit von der Anlage nach der DE-PS 19 19 749, als die Laufbahnen oben und unten um eine Einlauf- bzw. Auslaufstrecke verlängert sind Bei Abwärtsförderung gemäß Fig. 1 wird jedoch von der Einlaufstrecke an und bis in die Auslaufstrecke gefördert, wobei die Mitnehmerketten 7, die um vertikale Achsen laufen, senkrecht zu ihrer normalen Gelenkrichtung gekrümmt werden. Dafür ist nicht zwingend erforderlich, teure Kardangelenkketten zu verwenden; man kann vielmehr normale Rollenketten mit absichtlich vergrößertem Spiel zwischen Bolzen und Rollen verwenden. Wie Erprobungen gezeigt haben, ist der Mehrverschleiß ohne weiteres tragbar, da die Ketten in Zugrichtung nur schwach belastet sind.The design and arrangement of the raceways 5 and 6 for the non-braked wheels 3 of the cart 2 differs from the installation according to DE-PS 19 19 749 only to the extent that the raceways above and below are extended by an inlet and outlet section with downward conveyance 1 is, however, of the Inlet section promoted to and into the outlet section, the drive chains 7, which run around vertical axes, being curved perpendicular to their normal joint direction. It is not absolutely necessary to use expensive universal joint chains for this; one can rather use normal roller chains with deliberately increased play between pin and roller. As tests have shown, the additional wear is easily wearable because the chains are only slightly loaded in the direction of pull.

Wie die Draufsicht auf die Einlaufstrecke gemäß Fig. 2 erkennen läßt, sind die Umlenkkettenräder 9 seitlich nach außen versetzt, so daß die Ketten allmählich in den Eingriffsbereich zwischen Mitnehmernocken 8 und Anschlagstück 25 gelangen.As can be seen from the top view of the inlet section according to FIG. 2, the deflection sprockets 9 are laterally offset outwards, so that the chains gradually reach the engagement area between the driving cams 8 and the stop piece 25.

Der Antrieb der Ketten kann über eine Kegelradgetriebe von demselben Motor 10 aus erfolgen, der auch eine neben dem Schrägförderer vorgesehene Fahrtreppe antreibt, falls eine solche vorgesehen ist; die Fahrtrppe läuft dann aber schnel--ler als der Förderer, damit der Benutzer Zeit hat, den Karren in die Einlaufstrecke zu schieben und am Auslauf wieder in Empfang zu nehmen.The chains can be driven via a bevel gear from the same motor 10, which also drives an escalator provided next to the inclined conveyor, if one is provided; The escalator then runs faster than the conveyor, so that the user has time to push the cart into the infeed section and to receive it again at the outfeed.

Im Ausführungsbeispiel sind die Ketten 7 um Kettenräder geführt, die um horizontale Achsen umlaufen. Mit den auch in Querrichtung zumindest begrenzt biegsamen Ketten wäre auch eine Ausführungsform möglich, bei der die Umlenkung der Ketten um Kettenräder mit horizontalen Achsen erfolgt, doch wären dann wesentlich tiefere Gruben für die Antriebsaggregate erforderlich; insgesamt hat sich die dargestellte Ausführungsform als die wirtschaftlicher zu fertigende erwiesen.In the exemplary embodiment, the chains 7 are guided around sprockets that run around horizontal axes. With the chains, which are at least limitedly flexible in the transverse direction, an embodiment would also be possible in which the chains are deflected around sprockets with horizontal axes, but much deeper pits would then be required for the drive units; overall, the embodiment shown has proven to be the more economical to manufacture.
