Description

Die Erfindung betrifft ein Magazin für plattenförmige Gegenstände, das im wesentlichen horizontal ausgerichtet ist, und in dem die plattenförmigen Gegenstände unter Bildung eines Stapels, vorzugsweise mit geringer Neigung nach hinten, nebeneinanderstehend angeordnet sind, mit dem Magazin zugeordneten Vorrichtungen zum Vorschieben des Stapels zu seiner Entnahmestelle, der eine plattenförmige Gegenstände einzeln entnehmende Entnahmevorrichtung zugeordnet ist, und mit einer oberhalb des Stapels im Bereich der Entnahmestelle angeordneten, von oben an den Gegenständen angreifenden Niederhaltevorrichtung, die um eine quer zur Längserstreckung des Magazins ausgerichtete horizontale Achse pendelnd aufgehängt ist, und die einen am Vorderende des Stapels anzulegenden Anschlag aufweist.The invention relates to a magazine for plate-shaped objects, which is oriented essentially horizontally, and in which the plate-shaped objects are arranged side by side to form a stack, preferably with a slight inclination to the rear, with devices associated with the magazine for advancing the stack to its removal point , which is associated with a plate-shaped object individually removing removal device, and with a hold-down device arranged above the stack in the region of the removal point, which acts on the objects from above, which is suspended in an oscillating manner about a horizontal axis oriented transversely to the longitudinal extent of the magazine, and the one at Has front stop of the stack to be created.

Magazine mit Vorrichtungen zum Entnehmen von plattenförmigen Gegenständen aus einem in einem Magazin aufgenommenen Stapel solcher Gegenstände sind beispielsweise aus der AT-B-241 565, 329 124 und 352 198 bekannt. In diesen bekannten Magazinen sind die plattenförmigen Gegenstände übereinanderliegend aufgenommen. Die übereinanderliegende Anordnung der plattenförmigen Gegenstände im Stapel hat zur Folge, daß insbesondere bei größeren Stapeln bei der Entnahme des jeweils untersten plattenförmigen Gegenstandes erhebliche Reibungskräfte auftreten, die das Vereinzeln der plattenförmigen Gegenstände behindern. Dies ist insbesondere der Fall, wenn die plattenförmigen, im Magazin aufgenommenen Gegenstände Platten oder Scheider für Akkumulatoren sind. In der AT-B-352198 ist daher schon vorgeschlagen worden, im Abstand über der Entnahmestelle eine unabhängig von den Entnahmevorrichtungen betätigbare Klemmvorrichtung vorzusehen, um das Gewicht des Stapels beim Entnahmevorgang aufzufangen.Magazines with devices for removing plate-shaped objects from a stack of such objects accommodated in a magazine are known, for example, from AT-B-241 565, 329 124 and 352 198. In these known magazines, the plate-shaped objects are accommodated one above the other. The superimposed arrangement of the plate-shaped objects in the stack has the result that considerable friction forces occur, particularly in the case of larger stacks, when removing the bottom plate-shaped object in each case, which hinder the separation of the plate-shaped objects. This is particularly the case when the plate-shaped objects accommodated in the magazine are plates or separators for accumulators. In AT-B-352198 it has therefore already been proposed to provide a clamping device which can be actuated independently of the removal devices at a distance above the removal point in order to absorb the weight of the stack during the removal process.

Des weiteren gestaltet sich das Beschicken der bekannten vertikalen Stapel nicht immer einfach, da die plattenförmigen Gegenstände oben in die Magazine eingelegt werden müssen, was in der Regel von Hand erfolgen muß.Furthermore, loading the known vertical stacks is not always easy, since the plate-shaped objects have to be inserted into the top of the magazines, which usually has to be done by hand.

Ein Magazin für plattenförmige Gegenstände, das im wesentlichen horizontal ausgerichtet ist und in dem die plattenförmigen Gegenstände unter Bildung eines Stapels, vorzugsweise mit geringer Neigung nach hinten, nebeneinanderstehend angeordnet sind, mit dem Magazin zugeordneten Vorrichtungen zum Vorschieben des Stapels zu seiner Entnahmestelle, der eine plattenförmige Gegenstände einzeln entnehmende Entnahmevorrichtung zugeordnet ist, und mit einer oberhalb des Stapels im Bereich der Entnahmestelle angeordneten, von oben an den Gegenständen angreifenden Niederhaltevorrichtung ist beispielsweise aus der GB-B-1 581 764 bekannt. Die aus der GB-B-1 581 764 bekannte Niederhaltevorrichtung ist in einer gegenüber dem Magazin unveränderlichen Bewegungsebene auf- und abbewegbar, so daß das der Entnahmestelle zugekehrte Ende des Stapels plattenförmiger Gegenstände genau definiert sein muß, damit die bekannte Niederhaltevorrichtung die ihr zugeordnete Funktion auch erfüllen kann. Um die gegenüber der Niederhaltevorrichtung bei dem bekannten Magazin genau ausgerichtete Lage des zur Entnahme bereiten plattenförmigen Gegenstandes genau zu definieren, sind bei dem aus der GB-B-1 581 764 bekannten Magazin am entnahmeseitigen Ende desselben wegklappbare Rückhalteplatten vorgesehen. Derartige Rückhalteplatten behindern aber erfahrungsgemäß den Entnahmevorgang. Bei dem bekannten Magazin ist somit ein genau aufeinander abgestimmtes Wechselspiel der Bewegungen des Entnahmegreifers der Rückhalteplatten und der Niederhaltevorrichtung erforderlich. Überdies ist an der Niederhaltevorrichtung der GB-B-1 581 764 eine klingenartige Ablösevorrichtung für den vordersten Gegenstand vorgesehen. Mit dieser klingenartigen Ablösevorrichtung wird bei abgesenkter Niederhaltevorrichtung der vorderste Gegenstand oben vom Stapel getrennt, so daß er sich oben an mit der Niederhaltevorrichtung verbundene Rückhaltefinger anlehnt, bis er von der Entnahmevorrichtung angesaugt wird. Sowohl die Ablösevorrichtung als auch die Rückhaltefinger sind an der Niederhaltevorrichtung der GB-B-1 581 764 starr befestigt.A magazine for plate-shaped objects, which is aligned substantially horizontally and in which the plate-shaped objects are arranged side by side to form a stack, preferably with a slight inclination to the rear, with devices associated with the magazine for advancing the stack to its removal point, which is a plate-shaped One-by-one removal device is assigned, and a hold-down device arranged above the stack in the region of the removal point and engaging the objects from above is known, for example, from GB-B-1 581 764. The hold-down device known from GB-B-1 581 764 can be moved up and down in a movement plane which is invariable with respect to the magazine, so that the end of the stack of plate-shaped objects facing the removal point must be precisely defined so that the known hold-down device also performs the function assigned to it can meet. In order to precisely define the position of the plate-shaped object ready for removal in relation to the hold-down device in the known magazine, retractable retaining plates are provided in the magazine known from GB-B-1 581 764 at the end of the same on the removal side. Experience has shown that such retention plates hinder the removal process. In the known magazine, a precisely coordinated interplay of the movements of the removal gripper of the retaining plates and the holding-down device is required. In addition, a blade-like detachment device for the foremost object is provided on the hold-down device of GB-B-1 581 764. With this blade-like detaching device, the foremost object is separated from the top of the stack when the holding-down device is lowered, so that it rests on the retaining fingers connected to the holding-down device until it is sucked in by the removal device. Both the release device and the retaining fingers are rigidly attached to the hold-down device of GB-B-1 581 764.

Ein Magazin der eingangs genannten Gattung ist aus der US-A-2 119 585 bekannt. Die dort vorgesehene Niederhaltevorrichtung umfaßt eine gestellfest montierte Niederhalteplatte und einen das Vorderende des Stapels umgreifenden hakenartigen Anschlag. Dieser Anschlag ist an einem von einer horizontalen Welle getragenen Ausleger beweglich gelagert und wird von einer Feder nach unten gedrückt. Sowohl der hakenartige Anschlag als auch die Niederhalteplatte ragen über das entnahmeseitige Ende des Stapels, so daß beide von oben auch auf den zu entnehmenden Gegenstand einwirken.A magazine of the type mentioned is known from US-A-2 119 585. The hold-down device provided there comprises a hold-down plate fixed to the frame and a hook-like stop encompassing the front end of the stack. This stop is movably mounted on a boom supported by a horizontal shaft and is pressed down by a spring. Both the hook-like stop and the hold-down plate protrude beyond the removal end of the stack, so that both also act on the object to be removed from above.

Aus der US-A-3 612 251 ist ein Magazin bekannt, in dem nach vorne geneigt plattenförmige Gegenstände aufgenommen sind. Im Bereich der Oberkante des vorderen Endes des Stapels sind abwechselnd wirksame Rückhaltefinger vorgesehen. Diese Rückhaltefinger geben abwechselnd plattenförmige Gegenstände frei, die dann auf eine Fördereinrichtung fallen. Bei dessem Magazin ist weder eine Entnahmevorrichtung noch ein Niederhalter vorgesehen.From US-A-3 612 251 a magazine is known in which plate-shaped objects inclined forward are accommodated. In the area of the upper edge of the front end of the stack, alternately effective retention fingers are provided. These retaining fingers alternately release plate-shaped objects, which then fall onto a conveyor. Neither a removal device nor a hold-down device is provided in the magazine.

Der Erfindung liegt die Aufgabe zugrunde, ein Magazin der eingangs genannten Gattung zu schaffen, bei dem sich die Niederhaltevorrichtung selbsttätig gegenüber dem entnahmeseitigen Ende des im Magazin aufgenommenen Stapels plattenförmiger Gegenstände ausrichtet.The invention has for its object to provide a magazine of the type mentioned, in which the hold-down device automatically aligns itself with the removal end of the stack of plate-shaped objects accommodated in the magazine.

Erfindungsgemäß wird dies dadurch erreicht, daß der Abstand zwischen dem Anschlag und dem Niederhalter so bemessen ist, daß der Niederhalter zumindest der oberen Kante des von der Entnahmestelle aus gesehen zweiten plattenförmigen Gegenstandes zugeordnet ist, so daß der Entnahmegreifer lediglich den vordersten plattenförmigen Gegenstand aus dem Stapel entnimmt und daß der Niederhalter nach Entnahme eines plattenförmigen Gegenstandes anhebbar und vor der Entnahme des nächsten plattenförmigen Gegenstandes wieder absenkbar ist.According to the invention, this is achieved by that the distance between the stop and the hold-down device is dimensioned such that the hold-down device is assigned at least to the upper edge of the second plate-shaped object seen from the removal point, so that the removal gripper only removes the foremost plate-shaped object from the stack and that the hold-down device follows Removal of a plate-shaped object can be raised and lowered again before the next plate-shaped object is removed.

Durch diese Ausbildung der Niederhaltevorrichtung paßt sich diese selbsttätig und ohne jede Steuerung dem entnahmeseitigen Ende des Stapels aus plattenförmigen Gegenständen an. Durch den vorgesehenen Abstand zwischen Anschlag und Niederhalter der Niederhaltevorrichtung ist bei der Erfindung ebenfalls ohne jede besondere Steuerung zuverlässig gewährleistet, daß der Niederhalter genau oberhalb der Oberkante des, vom entnahmeseitigen Ende des Stapels aus gesehen, zweiten plattenförmigen Gegenstandes angeordnet ist. Dadurch wird anders als bei den aus der GB-B-1 581 764 und der US-A-2 119 585 bekannten Niederhaltevorrichtungen, die jeweils an mehreren am Entnahmeende des Magazins angeordneten plattenförmigen Gegenständen angreifen, zuverlässig gewährleistet, daß jeweils nur ein plattenförmiger Gegenstand entnommen wird. Dies ist besonders bei der Herstellung von Plattenstapeln im Zuge der Herstellung von Batterien von besonderer Bedeutung.This design of the hold-down device adapts itself automatically and without any control to the removal end of the stack of plate-shaped objects. The distance provided between the stop and the hold-down device of the hold-down device also reliably ensures in the invention without any special control that the hold-down device is arranged exactly above the upper edge of the second plate-shaped object, as seen from the removal-side end of the stack. In contrast to the hold-down devices known from GB-B-1 581 764 and US-A-2 119 585, which each engage a plurality of plate-shaped objects arranged at the removal end of the magazine, this reliably ensures that only one plate-shaped object is removed at a time becomes. This is particularly important in the production of plate stacks in the course of the production of batteries.

Das bevorzugte Anwendungsgebiet des erfindungsgemäßen Magazins ist daher auch dessen Verwendung in Vorrichtungen zur Herstellung von Plattenstapeln aus positiven und negativen Batterieplatten sowie den dazwischen anzuordnenden Scheidern. Dabei können mehrere Magazine in einer derartigen Vorrichtung nebeneinander angeordnet sein, wobei die Magazine beispielsweise einerseits positive und anderseits negative Batterieplatten enthalten.The preferred area of application of the magazine according to the invention is therefore also its use in devices for producing plate stacks from positive and negative battery plates and the separators to be arranged between them. Several magazines can be arranged next to one another in such a device, the magazines containing, for example, positive and negative battery plates on the one hand.

In einer besonders einfachen Ausführungsform der Erfindung ist vorgesehen, daß der Anschlag als Blattfeder ausgebildet ist. Da der Anschlag keine andere Aufgabe hat als den Niederhalter oberhalb des zweiten plattenförmigen Gegenstandes auzurichten, kann die Blattfeder weich ausgebildet sein, so daß sie den Entnahmevorgang nicht behindert, ohne daß dadurch ihre Funktion beeinträchtigt wird.In a particularly simple embodiment of the invention it is provided that the stop is designed as a leaf spring. Since the stop has no other task than aligning the hold-down device above the second plate-shaped object, the leaf spring can be made soft so that it does not hinder the removal process without impairing its function.

Es ist im Rahmen der Erfindung aber auch möglich, daß der Anschlag als mittels eines Druckmittelzylinders nach oben wegziehbarer Anschlag ausgebildet ist. Diese Ausführungsform wird bevorzugt bei Entnahmegreifern Anwendung finden, die den vordersten plattenförmigen Gegenstand wenigstens am Beginn des Entnahmevorganges mit einer parallel zur Längserstreckung des Magazins ausgerichteten Bewegungsbahn entnehmen.However, it is also possible within the scope of the invention that the stop is designed as a stop which can be pulled upwards by means of a pressure medium cylinder. This embodiment is preferably used for removal grippers which remove the foremost plate-shaped object at least at the beginning of the removal process with a movement path oriented parallel to the longitudinal extent of the magazine.

Da der Niederhalter zeitweise vom Plattenstapel nach oben abgehoben wird, richtet sich der Niederhalter, gesteuert vom Anschlag der Niederhaltevorrichtung, nach einem erfolgten Entnahmevorgang ohne zusätzliche Tätigkeiten wieder oberhalb des zweiten platteriförmigen Gegenstandes aus.Since the hold-down device is temporarily lifted up from the stack of plates, the hold-down device, controlled by the stop of the hold-down device, orients itself again after the removal process without additional activities above the second plate-shaped object.

In einer praktischen Ausführungsform der Erfindung kann vorgesehen sein, daß der Niederhalter, der Anschlag und deren Betätigungseinrichtungen an einer verschwenkbaren Platte montiert sind. Bevorzugt ist dabei vorgesehen, daß im oberen Endbereich der verschwenkbaren Platte ein durch ein Gewicht belasteter Ausleger befestigt ist, der von der dem Stapel gegenüberliegenden Seite der Platte weg ragt. Diese Ausführungsform hat den Vorteil, daß die Niederhaltevorrichtung nach erfolgtem Entnahmevorgang und bei nach oben zurückgezogenem Niederhalter rasch wieder in ihre Funktionslage verschwenkt. Zusätzlich besteht bei dieser Ausführungsform die Möglichkeit, den Anpreßdruck des Anschlages gegen das vordere, d. h. entnahmeseitige Ende des Stapels, durch Wahl der Größe, des Gewichtes oder durch Verschieben desselben gegenüber dem Ausleger auf den jeweils günstigsten Wert einzustellen.In a practical embodiment of the invention it can be provided that the hold-down device, the stop and their actuating devices are mounted on a pivotable plate. It is preferably provided that in the upper end region of the pivotable plate a cantilever which is loaded by a weight is fastened and which projects away from the side of the plate opposite the stack. This embodiment has the advantage that the hold-down device swings back into its functional position quickly after the removal process has taken place and when the hold-down device is retracted upwards. In addition, there is the possibility in this embodiment of the contact pressure of the stop against the front, ie. H. end of the stack on the removal side, by selecting the size, the weight or by moving the same relative to the delivery arm to the most favorable value.

Die zuverlässige Funktion des erfindungsgemäßen Magazins wird durch eine Ausführungsform der Erfindung unterstützt, nach welcher die Vorrichtung zum Vorschieben des Stapels im Magazin den beiden Hochkanten der den Stapel bildenden plattenförmigen Gegenstände zugeordnete, endlose Förderketten oder Förderbänder mit federnden Mitnehmern, die an den lotrechten Seitenflächen des Stapels anliegen, aufweist. Bei dieser Ausführungsform ist zuverlässig gewährleistet, daß der Stapel bzw. der vorderste plattenförmige Gegenstand des Stapels ohne Probleme in die Entnahmestellung vorgeschoben wird. Dadurch, daß die Mitnehmer der Förderketten oder Förderbänder rückfedernd ausgebildet sind, kann das Magazin durch einfaches Einschieben von Stapeln plattenförmiger Gegenstände von dem der Entnahmestelle gegenüberliegenden Ende des Magazins mit plattenförmigen Gegenständen beschickt werden.The reliable function of the magazine according to the invention is supported by an embodiment of the invention, according to which the device for advancing the stack in the magazine is assigned to the two vertical edges of the plate-shaped objects forming the stack, endless conveyor chains or conveyor belts with resilient drivers which are attached to the vertical side surfaces of the stack concern, has. In this embodiment, it is reliably ensured that the stack or the foremost plate-shaped object of the stack is pushed into the removal position without problems. Characterized in that the drivers of the conveyor chains or conveyor belts are resilient, the magazine can be loaded with plate-shaped objects by simply inserting stacks of plate-shaped objects from the end of the magazine opposite the removal point.

Damit die den Stapel bildenden, plattenförmigen Gegenstände an der Entnahmestelle des Magazins nicht nach vorne herauskippen können, kann im Rahmen der Erfindung vorgesehen sein, daß an jeder Seite des Magazins zwei übereinanderliegende Förderbänder oder -ketten vorgesehen sind und daß die Mitnehmer des jeweils oberen Förderbandes oder -kette gegenüber dem unteren Förderband oder -kette in Förderrichtung gesehen nach hinten versetzt angeordnet sind. Durch diese Anordnung der Mitnehmerklappen ist gewährleistet, daß die plattenförmigen Gegenstände im Magazin, von unten nach oben gesehen, schräg nach hinten geneigt stehen, was den Entnahmevorgang erleichtert.So that the stack-forming, plate-shaped objects cannot tip forward at the removal point of the magazine, it can be provided in the context of the invention that two superimposed conveyor belts or chains are provided on each side of the magazine and that the drivers of the respective upper conveyor belt or -Chain are arranged offset to the rear relative to the lower conveyor belt or chain as seen in the conveying direction. This arrangement of the driver flaps ensures that the plate-shaped objects in the magazine, as seen from the bottom up, are inclined obliquely backwards, which facilitates the removal process.

Um das Magazin an verschiedene Plattengrößen anpassen zu können, kann vorgesehen sein, daß der seitliche Abstand der Förderketten oder Förderbänder veränderbar ist, und daß die den seitlichen Kanten der den Stapel bildenden plattenförmigen Gegenstände zugeordneten oberen Führungsschienen des Magazins in Höhenrichtung verstellbar sind. Hiebei bewährt es sich im Rahmen der Erfindung, wenn die an beiden Seiten des Magazins angeordneten Führungsschienen und die Förderketten oder Förderbänder auf quer zur Längserstreckung des Magazins verschiebbaren Schlitten angeordnet sind. Damit die Führungsschienen und die Vorrichtungen zum Vorschieben des Plattenstapels auch bei Änderungen der Abmessungen des Magazins gegenüber dem Entnahmegreifer stets richtig ausgerichtet sind, kann vorgesehen sein, daß die Schlitten auf quer zur Längserstreckung des Magazins ausgerichteten Schienen verschiebbar geführt und über Lenkstangen mit einem in der Mitte des Magazins angeordneten, beispielsweise pneumatisch betätigten Stellorgan gekuppelt sind.In order to be able to adapt the magazine to different plate sizes, it can be provided that the lateral spacing of the conveyor chains or conveyor belts can be changed, and that the lateral edges of those forming the stack plate-shaped objects associated with the upper guide rails of the magazine are adjustable in the height direction. It has proven itself in the context of the invention if the guide rails arranged on both sides of the magazine and the conveyor chains or conveyor belts are arranged on slides which can be displaced transversely to the longitudinal extent of the magazine. So that the guide rails and the devices for advancing the stack of plates are always correctly aligned, even when the dimensions of the magazine are changed relative to the removal gripper, it can be provided that the slides are slidably guided on rails oriented transversely to the longitudinal extent of the magazine and via handlebars with one in the middle of the magazine arranged, for example pneumatically operated actuator are coupled.

Das Einschieben der plattenförmigen Gegenstände in das Magazin gestaltet sich besonders einfach, wenn dem aufgabeseitigen Ende des Magazins ein Einschubwagen für ein Paket plattenförmiger Gegenstände zugeordnet ist, dessen dem Paket zugekehrte Fläche nach hinten geneigt ist.The insertion of the plate-shaped objects into the magazine is particularly simple if the insertion end of the magazine is assigned a slide-in carriage for a package of plate-shaped objects, the surface of which faces the package is inclined to the rear.

Damit der Entnahmevorgang durch die Fördervorrichtung nicht behindert wird, kann erfindungsgemäß vorgesehen sein, daß die Förderketten oder Förderbänder vor der Entnahmestelle des Magazins außer Eingriff mit den plattenförmigen Gegenständen umgelenkt sind.So that the removal process is not hindered by the conveyor device, it can be provided according to the invention that the conveyor chains or conveyor belts are deflected out of engagement with the plate-shaped objects in front of the removal point of the magazine.

Für die verschwenkbare Lagerung des Entnahmegreifers sind die verschiedensten Möglichkeiten denkbar. Eine im Rahmen der Erfindung besonders geeignete ist dadurch gekennzeichnet, daß die Entnahmevorrichtung am Gestell des Magazins über einander kreuzende Lenkerpaare verschwenkbar gelagert ist. Bei einer derartigen Aufhängung der Entnahmevorrichtung bewährt es sich, wenn die am unteren Ende der in der Entnahmestellung befindlichen Entnahmevorrichtung angreifenden Lenker am Gestell weiter oben gelagert sind als die am anderen Ende der Entnahmevorrichtung angelenkten Lenker. Dadurch wird der Entnahmevorrichtung ohne zusätzliche Steuerungsmittel aus seiner im wesentlichen zur Seite weisenden Entnahmestellung in die nach unten weisenden, der Fördervorrichtung zugeordnete Abgabestellung gekippt.Various possibilities are conceivable for the pivotable mounting of the removal gripper. A particularly suitable in the context of the invention is characterized in that the removal device is pivotally mounted on the frame of the magazine over pairs of links. In such a suspension of the removal device, it is useful if the handlebars engaging at the lower end of the removal device in the removal position are mounted higher up on the frame than the handlebars articulated at the other end of the removal device. As a result, the removal device is tilted without additional control means from its removal position which points essentially to the side into the delivery position which points downward and is assigned to the conveying device.

Zur Betätigung der Entnahmevorrichtung können verschiedene Antriebe vorgesehen sein. So können zum Verschwenken der Entnahmevorrichtung aus der Entnahme- in die Abgabestellung und zurück ein Druckmittelzylinder, ein Kurbeltrieb oder ein Exzenterantrieb vorgesehen sein.Various drives can be provided to actuate the removal device. For example, a pressure medium cylinder, a crank drive or an eccentric drive can be provided for pivoting the removal device from the removal position into the delivery position and back.

Mit Vorteil ist im Rahmen der Erfindung vorgesehen, daß der Entnahmegreifer der Entnahmevorrichtung ein druckdicht ausgebildetes Gehause aufweist, an dem mindestens ein Vakuumsaugteller mit dem Inneren des Gehäuses kommunizierend angeordnet ist und daß im Inneren des Gehäuses des Entnahmegreifers eine Vakuumleitung unter Zwischenschaltung eines in der Entnahmestellung des Entnahmegreifers offenen, in der Abgabestellung geschlossenen Absperrorgans ausmündet. Bei dieser Ausführungsform wird ohne zusätzliche Steuerungsmittel der Vakuumsaugteller des Entnahmegreifers in der Entnahmestellung mit Vakuum beaufschlagt, wogegen er in der Ablegestellung von der Vakuumleitung getrennt ist. In einer praktischen Ausführungsform der Erfindung kann hiebei auch noch vorgesehen sein, daß an die Vakuumleitung ein in das Innere des druckdicht ausgebildeten Gehäuses des Entnahmegreifers führendes Rohrstück angeschlossen ist, das innerhalb des Gehäuses des Entnahmegreifers von einem im Gehäuse des Entnahmegreifers angeordneten Führungsrohr umgeben ist, und daß sowohl im Rohrstück als auch im Führungsrohr miteinander bei in seiner Entnahmestellung befindlichem Entnahmegreifer fluchtende Öffnungen vorgesehen sind.It is advantageously provided in the context of the invention that the removal gripper of the removal device has a pressure-tight housing on which at least one vacuum suction plate is arranged communicating with the interior of the housing and that in the interior of the housing of the removal gripper a vacuum line with the interposition of one in the removal position of the The removal gripper opens into the shut-off element which is closed in the delivery position. In this embodiment, the vacuum suction plate of the extraction gripper is subjected to vacuum in the removal position without additional control means, whereas it is separated from the vacuum line in the storage position. In a practical embodiment of the invention it can also be provided that a pipe piece leading into the interior of the pressure-tight housing of the removal gripper is connected to the vacuum line, which is surrounded within the housing of the removal gripper by a guide tube arranged in the housing of the removal gripper, and that aligned openings are provided both in the tube piece and in the guide tube with each other when the removal gripper is in its removal position.

Further details of the invention result from the following description of exemplary embodiments of the invention, in which reference is made to the drawing. It shows
  • FIG. 1 is a side view of a magazine for plate-shaped objects,
  • FIG. 2 the magazine in top view,

In einem Gestell 1 einer Vorrichtung, die beispielsweise Teil einer Maschine zum Bilden von Stapeln aus Batterieplatten ist, ist ein Magazin vorgesehen, in dem ein Stapel 6 aus nebeneinanderstehenden, plattenförmigen Gegenständen aufgenommen ist. Das Magazin wird seitlich von oberen Führungsschienen 7 und unteren Führungsschienen 19 gebildet. Sowohl der seitliche Abstand der einander paarweise gegenüberliegenden Führungsschienen 7 und 19 als auch der Höhenabstand der oberen Führungsschienen 7 von den unteren Führungsschienen 19 des Magazins ist zur Anpassung an verschiedene Größen plattenförmiger Gegenstände veränderbar.In a frame 1 of a device, which is, for example, part of a machine for forming stacks from battery plates, a magazine is provided in which a stack 6 of plate-shaped objects placed side by side is received. The magazine is formed laterally by upper guide rails 7 and lower guide rails 19. Both the lateral spacing of the guide rails 7 and 19 lying opposite one another in pairs and the height spacing of the upper guide rails 7 from the lower guide rails 19 of the magazine can be changed to adapt to different sizes of plate-shaped objects.

Dem Magazin ist weiters eine Vorrichtung zum Vorschieben des Plattenstapels 6 in die Entnahmestelle 33 zugeordnet, die jeweils zwei Kettenpaare 18 an jeder Seite des Magazins umfaßt. An den Ketten 18 sind federnde Mitnehmer 9 vorgesehen, die am Plattenstapel 6 angreifen.The magazine is also assigned a device for advancing the plate stack 6 into the removal point 33, which comprises two pairs of chains 18 on each side of the magazine. On the chains 18 resilient drivers 9 are provided which engage the plate stack 6.

Zum Beschicken des Magazins mit einem Plattenpaket 10 ist ein Platteneinschubwagen 11 vorgesehen, der auf feststehenden Führungsschienen 21 läuft. Durch die nach hinten geneigte Ausrichtung des Einschubwagens 11 werden die Platten in das Magazin mit geringer Neigung nach hinten eingeschoben.For loading the magazine with a plate pack 10, a plate insertion carriage 11 is provided, which runs on fixed guide rails 21. Due to the rearward inclined orientation of the slide-in carriage 11, the plates are pushed back into the magazine with a slight inclination.

Die auf beiden Seiten des Magazins vorgesehenen Führungsschienen 7 bzw. 19 und die aus den Ketten 18 mit den Mitnehmern 9 sowie aus Kettenrädern 22 bestehende Vorrichtung zum Vorschieben des Plattenstapels 6 sind jeweils auf Schlitten 23 montiert, die quer zur Längserstreckung des Magazins auf nicht gezeigten Führungsschienen verschiebbar gelagert sind. Die Schlitten sind über Lenkstangen mit einem beispielsweise pneumatisch oder hydraulisch betätigten Stellorgan 25 gekuppelt, so daß die Schlitten und damit die Führungen und die Vorrichtungen zum Fördern des Plattenstapels 6 symnetrisch bezüglich der Längsmittelachse des Magazins auseinander oder aufeinanderzu verschoben werden können. An Stelle des Stellorganes 25 kann auch ein Spindelantrieb vorgesehen sein.The guide rails 7 and 19 provided on both sides of the magazine and those from FIGS Chains 18 with the drivers 9 and sprocket 22 existing device for advancing the plate stack 6 are each mounted on slides 23 which are slidably mounted transversely to the longitudinal extent of the magazine on guide rails, not shown. The slides are coupled via handlebars to a pneumatically or hydraulically actuated actuator 25, for example, so that the slides and thus the guides and the devices for conveying the plate stack 6 can be moved apart or towards one another with respect to the longitudinal central axis of the magazine. Instead of the actuator 25, a spindle drive can also be provided.

Die Kettenräder 22 der oberen Ketten 8 und der unteren Ketten 18 sind auf Wellen 17 bzw. 20 angeordnet, wobei der Welle 17 ein Kettenantriebsrad zugeordnet ist.The sprockets 22 of the upper chains 8 and the lower chains 18 are arranged on shafts 17 and 20, respectively, the shaft 17 being assigned a chain drive wheel.

An der Entnahmestelle 33 des Magazins ist ein Entnahmegreifer 5 vorgesehen, der über einander kreuzende Lenkerpaare 2 und 4 am MaschinengesteIl 1 verschwenkbar gelagert ist. Zur Betätigung des Entnahmegreifers 5 ist ein Druckmittelzylinder 12 vorgesehen. Anstelle des im Ausführungsbeispiel nach Figur 1 gezeigten Entnahmegreifers 5 kann auch eine andere Entnahmevorrichtung vorgesehen sein.At the removal point 33 of the magazine, a removal gripper 5 is provided, which is pivotably mounted on the machine link 1 via pairs of links 2 and 4 which intersect. A pressure medium cylinder 12 is provided for actuating the removal gripper 5. Instead of the removal gripper 5 shown in the exemplary embodiment according to FIG. 1, another removal device can also be provided.

Aus Figur 1 ist ersichtlich, daß das Lenkerpaar 2, das am in der Entnahmestellung des Entnahmegreifers 5 unten befindlichen Ende angelenkt ist, am Maschinengestell 1 weiter oben gelagert ist als das Lenkerpaar 4, das am in der Entnahmestellung oberen Ende des Entnahmegreifers 5 angreift. Durch diese Anordnung der Lenkerpaare 2 und 4 ergibt sich ohne zusätzliche Steuerung bei Betätigung des Druckmittelzylinders 12 eine Kipp-Schwenkbewegung des Entnahmegreifers 5, wie dies in Figur 1 angedeutet ist.From Figure 1 it can be seen that the pair of links 2, which is articulated at the end located in the removal position of the removal gripper 5, is mounted higher up on the machine frame 1 than the pair of links 4, which acts on the upper end of the removal gripper 5 in the removal position. This arrangement of the handlebar pairs 2 and 4 results in a tilting-pivoting movement of the removal gripper 5 without additional control when the pressure medium cylinder 12 is actuated, as is indicated in FIG. 1.

Neben anderen möglichen Greiferausbildungen wird im Rahmen der Erfindung einem Entnahmegreifer 5, der mit mindestens einem Vakuumsaugteller 16 ausgerüstet ist, der Vorzug gegeben. Es versteht sich, daß an jedem Entnahmegreifer 5 auch mehrere Vakuumsaugteller 16 vorgesehen sein können.In addition to other possible gripper designs, preference is given in the context of the invention to a removal gripper 5 which is equipped with at least one vacuum suction plate 16. It goes without saying that a plurality of vacuum suction plates 16 can also be provided on each removal gripper 5.

Um den Vakuumsaugteller 16 des Entnahmegreifers 5 mit Vakuum beaufschlagen zu können, ist mindestens einer der Lenker des Lenkerpaares 2 als Vakuumleitung ausgebildet und über eine Leitung 3 an eine Unterdruckquelle angeschlossen.In order to be able to apply a vacuum to the vacuum suction plate 16 of the removal gripper 5, at least one of the links of the pair of links 2 is designed as a vacuum line and is connected via a line 3 to a vacuum source.

Sobald sich der Entnahmegreifer 5 in die in Figur 1 strichliert eingezeichnete Abgabestellung bewegt hat, wird der Vakuumsaugteller 16 nicht mehr mit Unterdruck beaufschlagt. Dadurch kann der vom Entnahmegreifer 5 aufgenomnene plattenförmige Gegenstand 14 auf eine Fördervorrichtung 13 (Maschinenförderband) abgelegt werden. Dies ist ohne weiteres möglich, wenn der plattenförmige Gegenstand porös ist und/oder eine rauhe Oberfläche aufweist, die dafür sorgt, daß das Vakuum in der Abgabestellung aufgehoben wird. Falls plattenförmige Gegenstände vereinzelt werden sollen, deren Struktur das selbsttätige Aufheben des Vakuums im Vakuumsaugteller 16 nicht erlaubt, dann wird das Vakuum im Vakuumsaugteller 16 aufgehoben. Das Beaufschlagen des Saugtellers 16 mit Vakuum und das Aufheben desselben kann durch nicht gezeigte, der Leitung 3 zugeordnete Ventile, die in Abhängigkeit von den Bewegungen des Entnahmegreifers 5 gesteuert werden, erfolgen. Dies kann auch durch die Bewegungen des Entnahmegreifers 5 gegenüber seinem Betätigungsgestänge (Lenkerpaare 2 und 4) gesteuert werden (vgl. Figur 4 und 5).As soon as the removal gripper 5 has moved into the delivery position shown in broken lines in FIG. 1, the vacuum suction plate 16 is no longer subjected to negative pressure. As a result, the plate-shaped object 14 picked up by the removal gripper 5 can be placed on a conveyor device 13 (machine conveyor belt). This is readily possible if the plate-shaped object is porous and / or has a rough surface, which ensures that the vacuum is released in the delivery position. If plate-shaped objects are to be separated, the structure of which does not allow the vacuum in the vacuum suction plate 16 to be released automatically, then the vacuum in the vacuum suction plate 16 is released. The suction plate 16 can be acted upon by vacuum and the same can be lifted by valves (not shown) assigned to the line 3, which are controlled as a function of the movements of the removal gripper 5. This can also be controlled by the movements of the removal gripper 5 relative to its actuating linkage (pairs of links 2 and 4) (cf. FIGS. 4 and 5).

Sobald ein plattenförmiger Gegenstand oder auch mehrere aus dem Stapel 6 im Magazin entnomnen worden ist bzw. sind, wird die Vorrichtung zum Vorschieben des Stapels 6 (Förderketten 8 und 18 mit den Mitnehmern 9) betätigt, so daß der nächste plattenförmige Gegenstand in die Entnahmestelle 33 vorgeschoben wird.As soon as one or more plate-shaped objects have been removed from the stack 6 in the magazine, the device for advancing the stack 6 (conveyor chains 8 and 18 with the drivers 9) is actuated so that the next plate-shaped object enters the removal point 33 is advanced.

Durch die erfindungsgemäße Ausgestaltung der Niederhaltevorrichtung 30 bzw. 31 ist es jedoch nicht nötig, das Ausmaß des Vorschubes des Stapels 6 auf die Entnahme von Platten genau abzustimmen. Es ist daher auch möglich, den Stapel 6 kontinuierlich vorzuschieben.Due to the design of the hold-down device 30 or 31 according to the invention, however, it is not necessary to precisely match the extent of the advance of the stack 6 to the removal of plates. It is therefore also possible to continuously advance the stack 6.

Insbesondere wenn mehrere nebeneinanderliegend angeordnete Magazine vorgesehen sind, können zur Betätigung der Entnahmegreifer 5 Exzenter- oder Kurbelantriebe 32 (vgl. Figur 3) vorgesehen sein. Diese Antriebe werden bevorzugt gemeinsam angetrieben.In particular if a plurality of magazines arranged next to one another are provided, 5 eccentric or crank drives 32 (cf. FIG. 3) can be provided for actuating the removal grippers. These drives are preferably driven together.

Der Entnahmegreifer 5 besitzt ein druckdicht ausgebildetes Gehäuse 5', mit dessen Innenraum der Vakuumsaugteller 16 kommuniziert. An das dem Entnahmegreifer 5 zugeordnete Ende des Lenkers 2 ist ein Rohrstück 2' angeschlossen, das in das Innere des Gehäuses 5' des Entnahmegreifers 5 führt. Im Gehäuse 5' des Entnahmegreifers 5 ist ein Führungsrohr 26 vorgesehen, in dem das Rohrstück 2' verdrehbar aufgenommen ist.The removal gripper 5 has a pressure-tight housing 5 ', with the interior of which the vacuum suction plate 16 communicates. At the end of the link 2 assigned to the removal gripper 5, a pipe section 2 'is connected, which leads into the interior of the housing 5' of the removal gripper 5. A guide tube 26 is provided in the housing 5 'of the removal gripper 5, in which the tube section 2' is rotatably received.

Figur 4 zeigt, daß im Rohrstück 2' eine Öffnung 27 vorgesehen ist, die in der in Figur 3 dargestellten Entnahmestellung mit einer Öffnung 28 im Führungsrohr 26 fluchtet.FIG. 4 shows that an opening 27 is provided in the pipe section 2 ′, which in the removal position shown in FIG. 3 is aligned with an opening 28 in the guide tube 26.

Auf diese Weise wird der Vakuumsaugteller 16 über das Innere des Gehäuses 5', die Öffnungen 28 und 27, das Rohrstück 2', den als Vakuumleitung ausgebildeten Lenker 2 und die Leitung 3 mit Unterdruck beaufschlagt.In this way, the vacuum suction plate 16 is subjected to negative pressure via the interior of the housing 5 ', the openings 28 and 27, the pipe section 2', the link 2 designed as a vacuum line and the line 3.

Sobald sich der Entnahmegreifer 5 in die in Figur 1 (strichliert) und Figur 5 gezeigte Abgabstellung bewegt hat, fluchten die Öffnungen 27 und 28 miteinander nicht mehr, so daß der Vakuumsaugteller 16 nicht mehr mit Unterdruck beaufschlagt wird. Dadurch kann der vom Entnahmegreifer 5 aufgenommene plattenförmige Gegenstand 14 auf eine Fördervorrichtung 13 abgelegt werden.As soon as the removal gripper 5 has moved into the delivery position shown in FIG. 1 (dashed line) and FIG. 5, the openings 27 and 28 no longer align with one another, so that the vacuum suction plate 16 is no longer subjected to negative pressure. As a result, the plate-shaped object 14 picked up by the removal gripper 5 can be placed on a conveyor device 13.

Über dem Plattenstapel 6 ist in dem Bereich der Entnahmestelle 33 des Magazins am Gestell 1 eine Niederhaltevorrichtung 30 um eine quer zur Längserstreckung des Magazins ausgerichtete horizontale Achse 34 verschwenkbar aufgehängt. Die Niederhaltevorrichtung 30 umfaßt eine längliche Platte 35, von deren oberem Ende ein durch ein Gewicht 36 belasteter Ausleger 37, der mit der Platte 35 starr verbunden ist, wegragt. Wie Figur 1 zeigt, ragt der Ausleger 37 von der Platte 35 auf der dem Plattenstapel 6 bzw. dem Magazin gegenüberliegenden Seite weg. Das Gewicht 36 kann am Ausleger 37 auswechselbar und/oder verschiebbar angeordnet sein.A hold-down device 30 is suspended above the plate stack 6 in the region of the removal point 33 of the magazine on the frame 1 about a horizontal axis 34 oriented transversely to the longitudinal extent of the magazine. The hold-down device 30 comprises an elongated plate 35, from the upper end of which a cantilever 37, which is loaded by a weight 36 and which is rigidly connected to the plate 35, projects away. As FIG. 1 shows, the extension 37 protrudes from the plate 35 on the side opposite the plate stack 6 or the magazine. The weight 36 can be exchangeably and / or displaceably arranged on the boom 37.

Am unteren Ende der Platte 35 ist ein Anschlag 38 vorgesehen, der unter der Einwirkung des Gewichtes der Niederhaltevorrichtung 30 gegen das Vorderende des Plattenstapels 6 anliegt.At the lower end of the plate 35, a stop 38 is provided which bears against the front end of the plate stack 6 under the influence of the weight of the holding-down device 30.

An der länglichen Platte 35 der Niederhaltevorrichtung 30 ist in einer Führung 40 verschiebbar ein Niederhalter 39 angeordnet, der mittels eines Druckmittelzylinders 41 auf den Plattenstapel 6 zu absenkbar und von diesem abhebbar ist.On the elongated plate 35 of the hold-down device 30, a hold-down device 39 is slidably arranged in a guide 40, which can be lowered onto the plate stack 6 by means of a pressure medium cylinder 41 and can be lifted off the latter.

Wie Figur 1 zeigt, ist der Abstand zwischen dem Anschlag 38 und dem Niederhalter 39 so bemessen, daß der Niederhalter 39 der oberen Kante des, von der Entnahmestelle 33 aus gesehen, zweiten plattenförmigen Gegenstandes im Plattenstapel 6 zugeordnet ist. Auf diese Weise kann die, von der Entnahmestelle 33 aus gesehen, zweite Platte des Plattenstapels 6 vom Niederhalter 39 durch entsprechende Beaufschlagung des Druckmittelzylinders 41 niedergehalten werden, so daß der Entnahmegreifer 5 lediglich die vorderste Platte aus dem Plattenstapel 6 entnimnt.As FIG. 1 shows, the distance between the stop 38 and the hold-down device 39 is dimensioned such that the hold-down device 39 is assigned to the upper edge of the second plate-shaped object in the plate stack 6, as seen from the removal point 33. In this way, as seen from the removal point 33, the second plate of the plate stack 6 can be held down by the hold-down device 39 by correspondingly acting on the pressure medium cylinder 41, so that the removal gripper 5 only removes the foremost plate from the plate stack 6.

Nach der Entnahme einer Platte wird der Niederhalter 39 durch Betätigung des Druckmittelzylinders 41 kurz angehoben, damit sich der Anschlag 38 wieder an das vordere, in der Entnahmestelle 33 befindliche Ende des Plattenstapels 6 anlegen kann, wobei die Niederhaltevorrichtung 30 um die Achse 34 verschwenkt. Es ist ersichlich, daß es dabei gleichgültig ist, ob der Plattenstapel 6 in der Zwischenzeit vorwärtsgeschoben wurde oder nicht.After a plate has been removed, the hold-down device 39 is briefly raised by actuating the pressure medium cylinder 41 so that the stop 38 can rest against the front end of the plate stack 6 located in the removal point 33, the hold-down device 30 pivoting about the axis 34. It can be seen that it does not matter whether the plate stack 6 has been pushed in the meantime or not.

Wie aus Figur 3 ersichtlich, kann an Stelle des beispielsweise als Blattfeder ausgebildeten Anschlages 38 an der länglichen Platte 35 der Niederhaltevorrichtung 31 ein durch einen weiteren Druckmittelzylinder 42 vor- und zurückschiebbarer Anschlag 43 vorgesehen sein, der an der länglichen Platte 35 in einer Führung 44 geführt ist. Diese Art des Anschlages gestattet eine problemlose Entnahme des jeweils vordersten plattenförmigen Gegenstandes aus dem Plattenstapel 6, selbst wenn der Entnahmegreifer den vordersten plattenförmigen Gegenstand wenigstens am Beginn des Entnahmevorganges im wesentlichen in Richtung der Längserstreckung des Magazins entnimmt.As can be seen from FIG. 3, instead of the stop 38, which is designed, for example, as a leaf spring, on the elongated plate 35 of the holding-down device 31, a stop 43 that can be pushed back and forth by a further pressure medium cylinder 42 is provided, which is guided in a guide 44 on the elongated plate 35 is. This type of stop permits problem-free removal of the foremost plate-shaped object from the plate stack 6, even if the removal gripper removes the foremost plate-shaped object essentially at least at the beginning of the removal process in the direction of the longitudinal extent of the magazine.

Nach der Entnahme des vordersten plattenförmigen Gegenstandes wird der Anschlag 43 wieder vorgeschoben und der Niederhalter 39 angehoben, so daß die Niederhaltevorrichtung 31 wieder in die in Figur 3 gezeigte Stellung verschwenken kann.After the removal of the foremost plate-shaped object, the stop 43 is advanced again and the hold-down device 39 is raised so that the hold-down device 31 can pivot again into the position shown in FIG. 3.

Gemäß einer nicht gezeigten Ausführungsform kann zur Betätigung des Niederhalters 39 und des beweglichen Anschlages 43 auch ein einziger Motor, beispielsweise ein Druckmittelmotor, vorgesehen sein, der über einen entsprechenden Schwenkhebelmechanismus beim Vorschieben des Niederhalters 39 den Anschlag 43 anhebt und umgekehrt.According to an embodiment not shown, a single motor, for example a pressure medium motor, can be provided for actuating the hold-down device 39 and the movable stop 43, which motor raises the stop 43 via a corresponding pivot lever mechanism when the hold-down device 39 is pushed forward and vice versa.
