Description

Die Erfindung bezieht sich auf einen Lastträger für Schleppkreisförderer gemäß dem einleitenden Teil von Anspruch 1.The invention relates to a load carrier for drag circuit conveyors according to the introductory part of claim 1.

Ein entsprechender mit einem kopflastigen Hilfsanschlag ausgebildeter Lastträger ist dem deutschen Patent 1 296 098 zu entnehmen. Dabei ist der kopflastige Hilfsanschlag mit einer Steuerrolle versehen, die im Übergangsbereich von einem Zugmittel zum anderen mit einer Auflauframpe oder Steuerkurve zusammenwirken muß, damit der Hilfsanschlag angehoben und von dem weiteren Mitnehmer erfaßt wird. Zu diesem Zweck ist es notwendig, daß die Hilfsrampe oder Steuerkurve im gesamten Übergangsbereich parallel zu der Laufbahn verläuft, was häufig zu konstruktiven Schwierigkeiten führt.A corresponding load carrier designed with a top-heavy auxiliary stop can be found in German Patent 1,296,098. The top-heavy auxiliary stop is provided with a control roller, which must cooperate in the transition area from one traction device to another with an overrun ramp or control cam, so that the auxiliary stop is raised and gripped by the other driver. For this purpose, it is necessary that the auxiliary ramp or control curve runs parallel to the raceway in the entire transition area, which often leads to constructional difficulties.

Aufgabe der vorliegenden Erfindung ist es, einen Lastträger der eingangs genannten Art derart auszubilden, daß ein problemloser Übergang von einem Zugmittel zu einem anderen gegeben ist, ohne daß im gesamten Übergangsbereich Hilfseinrichtungen wie zum Beispiel Steuerkurven oder Auflauframpen angeordnet sein müssen, die fortwährend mit dem Hilfsanschlag in Wechselwirkung treten.The object of the present invention is to design a load carrier of the type mentioned at the outset in such a way that there is a problem-free transition from one traction means to another without the need for auxiliary devices such as control cams or run-up ramps to be arranged in the entire transition area, which continuously with the auxiliary stop interact.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem Lastträger ein Arretierelement angeordnet ist, das den Hilfsanschlag nach dem Bewegen in den Weg des weiteren Mitnehmers in dieser Stellung hält. Dabei ist das Arretierelement vorzugsweise als ein federbetätigtes Element in Form von zum Beispiel einer Falle ausgebildet.The object is achieved in that a locking element is arranged on the load carrier, which holds the auxiliary stop after moving into the path of the other driver in this position. The locking element is preferably designed as a spring-actuated element in the form of, for example, a trap.

Durch die erfindungsgemäße Ausbildung ist es demzufolge nicht erforderlich, parallel im Übergangsbereich von einem Zugmittel zu einem anderen eine Rampe oder Laufkurve anzuordnen, die das Hochhalten des Hilfsanschlags bewirkt. Vielmehr ist aufgrund des Arretierelements sichergestellt, daß nach einem Bewegen, also Anheben in den Weg des Mitnehmers diese Stellung im gewünschten Umfang beibehalten wird. Nachdem der Übergang von einem Zugmittel zu einem anderen erfolgt ist, kann, nachdem die vordere Mitnahmevorrichtung erneut mit einem Mitnehmer in Eingriff gelangt ist, durch einen im Bereich des anderen Zugmittels angeordneten Auslösemechanismus das Arretierelement zurückgezogen werden, so daß der Hilfsanschlag in seine Grundstellung gelangt. Das Anheben selbst kann durch ein im Endbereich des zu verlassenden Zugmittels angeordnetes kurzes Kurvenstück oder eine entsprechend wirkende Einrichtung hervorgerufen werden.As a result of the design according to the invention, it is therefore not necessary to arrange a ramp or running curve in parallel in the transition region from one traction device to another, which causes the auxiliary stop to be held up. Rather, the locking element ensures that this position is maintained to the desired extent after it has been moved, that is, raised in the path of the driver. After the transition from one traction device to another has occurred, after the front driving device has again engaged a driver, the locking element can be pulled back by a release mechanism arranged in the area of the other traction device, so that the auxiliary stop reaches its basic position. The lifting itself can be brought about by a short curve piece arranged in the end region of the traction device to be exited, or a correspondingly acting device.

Durch die erfindungsgemäße Ausbildung des Lastträgers ist demzufolge die Möglichkeit gegeben, daß problemlos sogar der Übergang von einer Laufbahn zu einer anderen erfolgt, bei denen der Übergabebereich nicht geradlinig verläuft, sondern zum Beispiel einen kurvenförmigen oder ähnlichen Verlauf zeigt.The design of the load carrier according to the invention consequently gives the possibility that even the transition from one career path to another, in which the transfer area does not run in a straight line, but for example has a curved or similar course, takes place without any problems.

Nach einer besonders hervorzuhebenden Ausgestaltung der Erfindung ist das Arretierelement, das bevorzugt an der Tragkonstruktion des hinteren Laufwerks angeordnet ist, ein um vorzugsweise eine horizontale Achse schwenkbares Element wie zum Beispiel eine Klinke, die einen Vorsprung zum Beispiel in Form eines Nockens aufweist, durch den ein von dem Hilfsanschlag horizontal abragendes Element, wie zum Beispiel ein zylinderförmiger Vorsprung untergreifbar ist. Auch kann das Arretierelement so beschrieben werden, daß es im Bereich seines Anlenkpunktes keilförmig ausgebildet ist und eine Ausbuchtung aufweist, die mit dem abragenden Element des Hilfsanschlags in Wechselwirkung tritt, oder daß es ein ungleiche Schenkel aufweisender V-förmig ausgebildeter Hebel ist, der im Bereich seines Fußpunktes angelenkt ist und dessen kurzer Schenkel mit dem von dem Hilfsanschlag abragenden Element in Wechselwirkung tritt.According to a particularly noteworthy embodiment of the invention, the locking element, which is preferably arranged on the supporting structure of the rear drive, is an element which can preferably be pivoted about a horizontal axis, such as a pawl, which has a projection, for example in the form of a cam, through which a element projecting horizontally from the auxiliary stop, such as, for example, a cylindrical projection. The locking element can also be described in such a way that it is wedge-shaped in the region of its articulation point and has a bulge which interacts with the protruding element of the auxiliary stop, or that it is an uneven leg having a V-shaped lever which is in the region is articulated at its base and its short leg interacts with the element protruding from the auxiliary stop.

Besonders ist hervorzuheben, daß der Hilfsanschlag höhenverstellbar ist, wobei vorzugsweise die höhenverstellbare Bewegung von einem Abschnitt der hinteren Laufwerkkonstruktion geführt ist, der von zueinander beabstandeten Schenkelabschnitten des Hilfsanschlags umgeben ist. Die höhenverstellbare Bewegung kann dabei eine vertikale sein.It should be emphasized in particular that the auxiliary stop is height-adjustable, the height-adjustable movement preferably being guided by a section of the rear drive structure which is surrounded by spaced-apart leg sections of the auxiliary stop. The height-adjustable movement can be a vertical one.

Damit der Hilfsanschlag in seine angehobene Stellung gelangen kann, um also von dem weiteren Mitnehmer erfaßt zu werden, ist im Bereich vor dem Übergang von einem Zugmittel zu einem anderen im Bereich der Laufbahn eine Auflauframpe oder ein Kurvenstück derart angeordnet, daß eine Wechselwirkung mit dem abragenden Element des Hilfsanschlags erfolgt. Dadurch wird ein Anheben bewirkt, so daß die Ausbuchtung bzw. der kürzere Schenkel des Arretierelements das abragende Element untergreift, um es also in dieser Stellung zu halten. Nachdem eine Übergabe von einem Zugmittel zum anderen erfolgt ist, kann der Hilfsanschlag dadurch in seine Grundstellung zurückbewegt werden (Herabfallen vorzugsweise aufgrund seiner Schwerkraft), daß das freie obere Ende des um die horizontale Achse schwenkbaren Elements in Form der Klinke oder ähnlichem mit einem Entarretierelement in Form von zum Beispiel einem Vorsprung in Wechselwirkung tritt, um ihn von dem Hilfsanschlag wegzubewegen, so daß das Arretierelement den seitlich abragenden Vorsprung des Hilfsanschlags nicht mehr untergreift.So that the auxiliary stop can reach its raised position, so that it can be grasped by the other driver, a ramp or a curve piece is arranged in the area before the transition from one traction device to another in the area of the track in such a way that an interaction with the protruding one Element of the auxiliary stop is done. This causes lifting, so that the bulge or the shorter leg of the locking element engages under the projecting element, so that it can be held in this position. After a transfer from one traction device to another has taken place, the auxiliary stop can be moved back into its basic position (preferably falling due to its gravity) in that the free upper end of the element pivotable about the horizontal axis in the form of the pawl or the like with a locking element in Form of, for example, a projection interacts to move it away from the auxiliary stop so that the locking element no longer engages under the laterally projecting projection of the auxiliary stop.

In den Fig. 1 und 2 ist in Seitenansicht bzw. Draufsicht ein Ausschnitt eines Schleppkreisfördersystems dargestellt, in dem ein Lastträger 10 von einem Zugmittel 12 auf ein anderes Zugmittel 14 übergeben werden soll. Eine Laufbahn 16, 20 für den Lastträger (10) ist im Übergangsbereich mit dem Bezugszeichen 18 versehen.1 and 2, a side view and plan view, respectively, show a section of a drag chain conveyor system in which a load carrier 10 to be transferred from one traction device 12 to another traction device 14. A track 16, 20 for the load carrier (10) is provided with the reference symbol 18 in the transition area.

Der Lastträger 10 weist ein vorderes Laufwerk 22 und ein hinteres Laufwerk 24 auf, die über eine Kuppelstange 26 miteinander verbunden sind. Am vorderen Laufwerk 22 ist eine Mitnahmevorrichtung 28 vorzugsweise in Form einer Ausklinkvorrichtung angeordnet, die mit einem am Zugmittel 12 vorhandenen Mitnehmer 30 in Eingriff gelangt, um den Lastträger 10 entlang der Laufbahn 16, 20 in Pfeilrichtung transportieren zu können.The load carrier 10 has a front drive 22 and a rear drive 24, which are connected to one another via a coupling rod 26. A driving device 28, preferably in the form of a notching device, is arranged on the front drive 22, which engages with a driver 30 provided on the traction means 12 in order to be able to transport the load carrier 10 along the track 16, 20 in the direction of the arrow.

Das hintere Laufwerk 24 ist mit einem Hilfsanschlag 32 versehen, der vertikal verschiebbar ist. Wie Fig. 1 verdeutlichen soll, kann dabei der Hilfsanschlag 32 derart angehoben werden (gestrichelte Darstellung), daß er von einem weiteren Mitnehmer 46 erfaßt wird, damit der Lastträger 10 auch dann fortbewegt werden kann, wenn der Mitnehmer 30 nicht im Eingriff mit der Mitnahmevorrichtung 28 liegt, wenn also der Lastträger 10 von dem Laufbahnteil 16 mit dem Zugmittel 12 auf dem Laufbahnteil 20 mit dem Zugmittel 14 übergeben werden soll.The rear drive 24 is provided with an auxiliary stop 32 which can be moved vertically. As is to be shown in FIG. 1, the auxiliary stop 32 can be raised (dashed line) in such a way that it is gripped by a further driver 46 so that the load carrier 10 can also be moved when the driver 30 is not in engagement with the driver device 28 lies if the load carrier 10 is to be transferred from the track part 16 with the traction means 12 to the track part 20 with the traction means 14.

Der Hilfsanschlag 32 wirkt seinerseits mit einem Arretierelement 34 zusammen, welches im Zusammenhang mit den Fig. 3 und 4 noch beschrieben wird. Des weiteren ist in Fig. 1 erkennbar, daß im Bereich der Laufbahn 16 ein Kurvenstück oder eine Auflauframpe 36 angeordnet ist, entlang der ein Vorsprung des Hilfsanschlags 32 gleitet. Ferner ist im Bereich des Laufbahnteils 20 ein Vorsprung 38 angeordnet, der das Arretierelement 34 derart verschwenkt, daß der Hilfsanschlag 32 in seine Grundstellung zurückfällt.The auxiliary stop 32 in turn interacts with a locking element 34, which will be described in connection with FIGS. 3 and 4. Furthermore, it can be seen in FIG. 1 that in the region of the track 16 there is a curve piece or an ramp 36 along which a projection of the auxiliary stop 32 slides. Furthermore, a projection 38 is arranged in the region of the raceway part 20, which pivots the locking element 34 in such a way that the auxiliary stop 32 falls back into its basic position.

In den Fig. 3 und 4 ist in vergrößerter Darstellung das hintere Laufwerk 24 dargestellt, welches aus einem Art kreuzförmigen Grundkörper 40 besteht, an dessen horizontal verlaufenden Schenkeln Spurrollen 42 bzw. 44 sowie Räder 48 und 50 angeordnet sind, die entlang der horizontal verlaufenden Schenkel der aus U-Profilen zusammengesetzten Laufbahn 16 bzw. 20 entlanggleiten.3 and 4, the rear drive 24 is shown in an enlarged view, which consists of a kind of cruciform base body 40, on the horizontally extending legs of track rollers 42 and 44 and wheels 48 and 50 are arranged along the horizontally extending legs glide along the track 16 or 20 composed of U-profiles.

Vorzugsweise ist der Hilfsanschlag 32 mittig im vertikal verlaufenden Schenkel des Grundkörpers 40 angeordnet und weist in einem Abschnitt zwei zueinander beabstandete Schenkel auf, zwischen den ein am Grundkörper 40 vorhandener Steg als Führungselement für die Hilfsanschlagbewegung angeordnet ist. Nähme man also entlang der horizontal verlaufenden Abschnitte des Laufwerks 24 einen Schnitt vor und würde diesen in Draufsicht betrachten, so würden sich im Bereich des Hilfsanschlags 32 die horizontal verlaufenden Schenkel des Grundkörpers 40 verjüngen.The auxiliary stop 32 is preferably arranged centrally in the vertically extending leg of the base body 40 and has in one section two spaced legs, between which a web on the base body 40 is arranged as a guide element for the auxiliary stop movement. If one were to make a cut along the horizontally running sections of the drive 24 and would view this in plan view, the horizontally extending legs of the base body 40 would taper in the region of the auxiliary stop 32.

In Fig. 3 ist der Hilfsanschlag 32 am Laufwerk 24 in einer Position dargestellt, in der ein Erfassen von einem Mitnehmer nicht erfolgen kann. Soll nun eine Übergabe von dem Laufbahnteil 16 auf den Laufbahnteil 20 erfolgen, so gelangt der Mitnehmer 30 gemäß Fig. 1 in Ausgriff von der Ausklinkvorrichtung 28. Damit ein Weitertransport erfolgen kann, muß nun der Hilfsanschlag 32 von der Grundposition in die angehobene Position 32 gehoben werden. Zu diesem Zweck ist im unteren Bereich des Hilfsanschlags 32 ein seitlich abragender Vorsprung 52 in Form zum Beispiel eines Zylinderabschnitts angeordnet, welcher entlang der Auflauframpe bzw. mit dem Kurvenstück 36 derart führbar ist, daß ein Anheben in Pfeilrichtung erfolgt.In Fig. 3, the auxiliary stop 32 on the drive 24 is shown in a position in which a driver can not be detected. If a transfer from the raceway part 16 to the raceway part 20 is to take place, then the driver 30 according to FIG. 1 comes into engagement with the release device 28. In order for further transport to take place, the auxiliary stop 32 must now be lifted from the basic position into the raised position 32 will. For this purpose, a laterally projecting projection 52 in the form of, for example, a cylinder section is arranged in the lower region of the auxiliary stop 32, which can be guided along the ramp or with the curve piece 36 in such a way that it is lifted in the direction of the arrow.

Dabei erfolgt das Anheben des Hilfsanschlags 32 in einem Umfang, daß ein Bereich des Arretierelements 34 den Vorsprung 52 untergreifen kann. Zu diesem Zweck ist das Arretierelement 34 vorzugsweise keilförmig ausgebildet und weist im unteren Bereich eine Ausnehmung 54 auf, in die der Vorsprung 52 einlegbar ist.The auxiliary stop 32 is raised to such an extent that a region of the locking element 34 can engage under the projection 52. For this purpose, the locking element 34 is preferably wedge-shaped and has a recess 54 in the lower region, into which the projection 52 can be inserted.

Das Arretierelement 34 selbst ist um eine im unteren Bereich horizontal verlaufende Achse 56 drehbar gelagert und wird über eine Stange 58, die von einem Federelement 60 umgeben ist, in Richtung auf den Hilfsanschlag 32 gedrückt. Befindet sich nun der Vorsprung 52 oberhalb der Ausnehmung 54, so kann das Arretierelement 34 weiter in Richtung des Hilfsanschlags 32 bewegt werden (siehe Fig.4), so daß dann, wenn der Vorsprung 52 nicht mehr mit dem Kurvenstück 34 zusammenwirkt, der Vorsprung 52 in diese Ausnehmung 54 fällt, so daß also der Hilfsanschlag 32 in seiner angehobenen Stellung verharrt.The locking element 34 itself is rotatably supported about an axis 56 running horizontally in the lower region and is pressed in the direction of the auxiliary stop 32 via a rod 58 which is surrounded by a spring element 60. If the projection 52 is now above the recess 54, the locking element 34 can be moved further in the direction of the auxiliary stop 32 (see FIG. 4), so that when the projection 52 no longer interacts with the curve piece 34, the projection 52 falls into this recess 54, so that the auxiliary stop 32 remains in its raised position.

Sodann kann das obere freie Ende des Hilfsanschlags 32 von dem Mitnehmer 46 erfaßt werden, damit eine Übergabe von dem Laufbahnteil 16 auf den Laufbahnteil 20 über den Übergangsbereich 18 erfolgen kann. Sobald das vordere Laufwerk mit seiner Mitnahmevorrichtung 28 in Eingriff mit einem am Zugmittel 14 vorgesehenen Mitnehmer gelangt, ist die Aufgabe des Hilfsanschlags 32 erfüllt, so daß ein Herabgleiten aufgrund vorzugsweise der Schwerkraft oder auch zum Beispiel durch eine von einer Feder hervorgerufene Zwangskraft in die Grundstellung (Fig. 3) erfolgen darf. Zu diesem Zweck befindet sich im Bereich des Laufbahnteils 20 ein Vorsprung 38, welcher gegen den in bezug auf die Achse 56 entfernt liegenden Bereich des Arretierelements 34 anschlägt, so daß dieses von dem Hilfsanschlag 32 weggeschwenkt wird, wodurch ein Herunterfallen des Anschlags 32 in die Grundstellung erfolgt.Then the upper free end of the auxiliary stop 32 can be gripped by the driver 46 so that a transfer from the track part 16 to the track part 20 can take place via the transition region 18. As soon as the front drive with its driving device 28 comes into engagement with a driver provided on the traction means 14, the task of the auxiliary stop 32 is fulfilled, so that a sliding down into the basic position (preferably due to gravity or also, for example, by a force caused by a spring) Fig. 3) may take place. For this purpose, there is a projection 38 in the region of the raceway part 20, which abuts against the region of the locking element 34 which is distant with respect to the axis 56, so that it is pivoted away from the auxiliary stop 32, causing the stop 32 to drop into the basic position he follows.

Demzufolge befindet sich der Lastträger 10 wieder in seinem normalen Transportzustand und wird von einem Mitnehmer des Zugmittels 14 transportiert, welches mit der Ausklinkvorrichtung 28 in Eingriff gelangt.As a result, the load carrier 10 is again in its normal transport state and is transported by a driver of the traction means 14, which comes into engagement with the notching device 28.
