Description

Die Erfindung betrifft eine Vorrichtung mit den Merkmalen des einleitenden Teils von Anspruch 1, wie sie aus der DE-A-3202087 bekannt ist.The invention relates to a device having the features of the introductory part of claim 1, as known from DE-A-3202087 is known.

Vorrichtungen zum Vereinzeln von plattenförmigen Gegenständen, insbesondere von Batterieplatten, aus Stapeln solcher plattenförmiger Gegenstände sind bekannt.Devices for separating plate-shaped objects, in particular battery plates, from stacks of such plate-shaped objects are known.

In älteren Vorschlägen für Vorrichtungen zum Entnehmen von Batterieplatten aus Stapeln solcher Batterieplatten (vgl. AT 241 565 B , AT 329 124. B und AT 352 198 B ) sind die Batterieplatten in im wesentlichen lotrechten Stapeln, in welchen die Platten im wesentlichen horizontal ausgerichtet sind, angeordnet und werden von unten aus dem Stapel entnommen. Dies ist wegen des auf der jeweils untersten Platte lastenden Gewichts des Stapels problematisch, da es vorkommt, dass die Batterieplatten aneinander haften und nicht ohne weiteres einzeln entnommen werden können.In older proposals for devices for removing battery plates from stacks of such battery plates (see. AT 241 565 B . AT 329 124. B and AT 352 198 B ), the battery plates are arranged in substantially vertical stacks, in which the plates are oriented substantially horizontally, and are taken from below from the stack. This is problematic because of the weight of the stack on the bottom plate in each case, since it happens that the battery plates adhere to one another and can not easily be removed individually.

Es sind daher auch schon Vorrichtungen vorgeschlagen worden, in welchen den Batterieplatten im wesentlichen lotrecht stehend in horizontal ausgerichteten Stapeln der Entnahmestelle zugeführt werden.Therefore, devices have already been proposed in which the battery plates are fed substantially vertically standing in horizontally aligned stacks of the sampling point.

Beispielhaft wird auf die EP 0 141 806 B , die EP 0 608 678 A und die AT 405 824 B verwiesen.Exemplary is on the EP 0 141 806 B , the EP 0 608 678 A and the AT 405 824 B directed.

Bei diesen bekannten Vorrichtungen werden die zu vereinzelnden Platten im wesentlichen lotrecht stehend in horizontal ausgerichteten Stapeln einer Vereinzelungsvorrichtung mit einem Greifer zugeführt, der Platten einzeln aus dem Stapel entnimmt. Dies bedingt eine aufwendige Kinematik des Greifers ("Plattenleger"), welcher einzelne Platten aus dem Stapel entnimmt und auf ein Förderband ablegt.In these known devices, the plates to be separated are fed substantially vertically standing in horizontally aligned stacks of a separating device with a gripper, which removes plates individually from the stack. This requires a complex kinematics of the gripper ("plate"), which removes individual plates from the stack and places on a conveyor belt.

Nachteilig bei diesen bekannten Vorrichtungen ist es, dass diese wegen der komplizierten Bewegungen der Entnahmegreifer, welche die Platzen einzeln aus horizontalen Stapeln entnehmen sollen, hinsichtlich ihrer Leistungsfähigkeit begrenzt sind.A disadvantage of these known devices is that they are limited in terms of their performance because of the complicated movements of the removal gripper, which should remove the bursts individually from horizontal stacks.

Aus der US 2003/0012636 A ist eine Vorrichtung zum Vereinzeln von plattenförmigen Gegenständen aus lotrechten Stapeln bekannt, wobei der Stapel von oben her abgearbeitet wird. Von einem Förderer zugeführte Stapel werden von Hebelvorrichtungen angehoben. Dem oberen Ende des Stapels ist ein Entnahmegreifer zugeordnet, der mit Saugköpfen ausgestattet ist und über einen Antrieb Vertikalbewegungen ausführt. Die vom Entnahmegreifer mit seinen Saugköpfen vom oberen Ende abgehobene Platte wird an einem von vier Saugkästen, die an einem sich drehenden Rad angeordnet sind, übergeben. Von diesen Saugkästen werden die Platten dann auf ein weiteres Förderband aufgelegt, wobei sie bei ihrer Bewegung zwischen der Aufgabestelle im Bereich des Entnahmegreifers und der Abgabestelle eine 180'-Drehung ausführen.From the US 2003/0012636 A is a device for separating plate-shaped Objects from vertical stacks known, the stack is processed from above. Stacks fed by a conveyor are lifted by lever devices. The upper end of the stack is associated with a removal gripper, which is equipped with suction cups and performs vertical movements via a drive. The lifted from the removal gripper with its suction cups from the top end plate is passed to one of four suction boxes, which are arranged on a rotating wheel. From these suction boxes, the plates are then placed on another conveyor belt, wherein they perform a 180 'rotation in their movement between the feed point in the region of the picking gripper and the discharge point.

Gemäß der DE 32 02 087 A wird ein lotrechter Stapel von oben her abgearbeitet, wobei beim Abheben von Platten vom Stapel eine nach oben gerichtete Bewegung ausgeführt wird. Zum Abarbeiten ist ein Endlosförderband mit daran mit Unterdruck beaufschlagten Saugköpfen vorgesehen. Dieses Förderband transportiert abgenommene Platten (einzeln) zu einem weiteren Förderer, mit dem vereinzelte Platten abtransportiert werden. Die eine Umlenkrolle des Förderbandes mit den Saugköpfen, nämlich die Umlenkrolle, die im Bereich des Stapels angeordnet ist, ist in einem Schlitten auf und ab verschiebbar gelagert. Von diesem Stand der Technik geht die Erfindung aus.According to the DE 32 02 087 A a vertical stack is processed from the top, wherein the lifting of plates from the stack an upward movement is performed. To process an endless conveyor belt is provided with it acted upon by vacuum suction cups. This conveyor transports removed plates (individually) to another conveyor, with which individual plates are transported away. The one deflection roller of the conveyor belt with the suction heads, namely the deflection roller, which is arranged in the region of the stack, is mounted in a slide up and down. From this prior art, the invention is based.

Die US 4,516,762 A befasst sich mit einer Vorrichtung zum Aufnehmen und Entfernen einzelner Beutel von einem Stapel, wobei diese Beutel einer Beutelfüllmaschine zugeführt werden sollen. Beutelstapel werden auf einem Förderer herangefördert und unterhalb der Beutelentnahmevorrichtung positioniert. Neben dem Förderer für Stapel von Beuteln ist ein zweiter Förderer für vereinzelte Beutel vorgesehen. Zum Abheben einzelner Beutel ist eine mit Saugköpfen bestückte Vorrichtung vorgesehen, die lediglich auf und ab beweglich ist. Wenn ein Beutel vom Stapel abgehoben worden ist, werden Finger von beiden Seiten her unter den abgehobenen Beutel eingebracht und dann der Beutel von einer verschiebbaren Vorrichtung, welche die Finger trägt, unter Klemmen seitlich über den Förderer bewegt und auf diesen abgelegt.The US 4,516,762 A deals with a device for picking up and removing individual bags from a stack, which bags are to be fed to a bag filling machine. Bag stacks are conveyed on a conveyor and positioned below the bag picking device. In addition to the conveyor for stacks of bags, a second conveyor for individual bags is provided. For lifting individual bags, a device equipped with suction heads is provided, which is movable only up and down. When a bag has been lifted off the stack, fingers are inserted from both sides under the lifted bag, and then the bag is moved laterally over the conveyor and deposited on a conveyor by a slidable device which carries the fingers.

In der DE 40 05 144 A wird ein Bogenanleger beschrieben, bei dem auf einem auf und ab bewegbaren Träger Trennsauger und wenigstens eine Reihe von Schleppsaugern auf einem hin- und herbewegbaren Träger vorgesehen sind. Irgendwelche Übereinstimmungen mit dem Gegenstand der Anmeldung sind nicht erkennbar.In the DE 40 05 144 A a sheet feeder is described in which are provided on a reciprocally movable carrier separating suction and at least one row of Schleppsaugern on a reciprocable carrier. Any matches with the subject of the application are not recognizable.

Die US 4, 439, 097 A befasst sich mit einer Einrichtung, mit der Trennblätter zwischen Zeitschriftenbündeln eingeführt werden sollen. Dabei werden die Trennblätter von einem Greifer aufgenommen und auf einen Förderer aufgelegt, der diese zwischen Lagen aus Zeitschriftenbündeln einschiebt.The US 4, 439, 097 A deals with a device intended to introduce dividers between magazine bundles. The separator sheets are picked up by a gripper and placed on a conveyor, which inserts these between layers of magazine bundles.

Eine erfindungsgemäße Vorrichtung, wie sie in Fig. 1 und 2 gezeigt ist, besitzt ein Förderband 10 zum Heranfördern von Stapeln aus Platten, insbesondere positiven und/oder negativen (Blei-) Platten für Batterien und Akkumulatoren, und eine im Anschluss an dieses Förderband 10 (Stapelzubringerband) angeordnete Vorrichtung 30 zum Anheben von Stapeln zu einer Vereinzelungsstation 50 mit einem Plattenleger 51 und einer Vorrichtung 58 zum Vereinzeln von Platten. Im Anschluss an die Vereinzelungsstation 50 ist ein Saugförderband 70 (Vakuumband) vorgesehen, mit welchem die in der Vereinzelungsstation 50 vereinzelten und auf einen Zwischenförderer 60 abgelegten Platten zu einer Hauptförderbahn 90 zugeführt werden.A device according to the invention, as in Fig. 1 and 2 is shown has a conveyor belt 10 for conveying stacks of plates, in particular positive and / or negative (lead) plates for batteries and accumulators, and a subsequent to this conveyor belt 10 (Stapelerbringerband) arranged device 30 for lifting stacks to one Separation station 50 with a plate 51 and a device 58 for separating plates. Subsequent to the separating station 50, a suction conveyor belt 70 (vacuum belt) is provided, with which the plates separated in the separating station 50 and deposited on an intermediate conveyor 60 are fed to a main conveyor track 90.

Die einzelnen Baugruppen der Vorrichtung werden nachstehend beschrieben:The individual components of the device are described below:

Das Stapelzubringerband 10 ist beispielsweise ein Riemen- oder Kettenförderer 11 mit im Ausführungsbeispiel drei Förderelementen 12 (Riemen oder Ketten), auf deren im Bereich des in Fig. 1 links liegenden Enden der oberen Trume der Förderelemente 12, die sich in Fig. 1 nach rechts bewegen, von einer beliebigen Vorrichtung 13 Stapel 14 (Fig. 2) von Platten aufgesetzt werden. Den oberen Trumen der Förderelemente 12 des Stapelzubringerbandes 10 sind zwei Hebevorrichtungen 15 zugeordnet, welche auf dem Zubringerband 10 angeordnete Stapel 14 von den Förderelementen 12 zum Anhalten der Stapel 14 abheben können, so dass diese geordnet und mit Abstand voneinander zu der Hebevorrichtung 30, die am abgabeseitigen Ende des Stapelzubringerbandes 10 angeordnet ist, zugeführt werden können.The stack conveyor belt 10 is, for example, a belt or chain conveyor 11 with in the exemplary embodiment three conveying elements 12 (belts or chains), on whose in the region of in Fig. 1 lying left ends of the upper strands of the conveying elements 12, which in Fig. 1 move to the right, from any device 13 stack 14 ( Fig. 2 ) are mounted by plates. The upper runs of the conveying elements 12 of the stack conveyor belt 10 are associated with two lifting devices 15, which can lift off on the feeder belt 10 stack 14 of the conveyor elements 12 to stop the stack 14, so that these ordered and spaced from each other to the lifting device 30, the on Abgabeseitigen end of the stack conveyor belt 10 is arranged, can be supplied.

Die Hebevorrichtung 30 (vgl. Fig. 10.1 und 10.2) besitzt zwei unabhängig voneinander betätigbare Hebetische 31 und 32, von welchen einer 31 in seiner unteren Ausgangslage im unteren Bereich, also im wesentlichen in der Höhe der oberen Trume der Förderelemente 12 des Stapelzubringerbandes 10 angeordnet ist. Dieser untere Hebetisch 31 besitzt im Ausführungsbeispiel zwei Finger 33, die in der unteren Endstellung zwischen die Förderelemente 12 (Ketten, Bänder oder Riemen) des Stapelzubringerbandes 10 eingreifen.The lifting device 30 (see. Fig. 10.1 and 10.2 ) has two independently operable lifting tables 31 and 32, of which a 31 in its lower starting position in the lower region, that is arranged substantially at the height of the upper strands of the conveying elements 12 of the Stapelzubringerbandes 10. This lower lifting table 31 has in the exemplary embodiment two fingers 33, which engage in the lower end position between the conveying elements 12 (chains, belts or belts) of the Stapelzubringerbandes 10.

Der zweite Hebetisch 32 ist im oberen Bereich der Hebevorrichtung 30 angeordnet. An dem oberen Hebetisch 32 ist wenigstens ein in die Hebebahn vor- und zurückschiebbares Schwert 34 vorgesehen - vorzugsweise sind drei Schwerter 34 vorgesehen, die zwischen die Finger 33 des unteren Hebetisches 31 eingreifen können - um einen teilweise abgearbeiteten Stapel 14 vom unteren Hebetisch 31 zu übernehmen.The second lifting table 32 is arranged in the upper area of the lifting device 30. On the upper lifting table 32 at least one forward and zurückschiebbares in the hoistway sword 34 is provided - preferably three swords 34 are provided which can engage between the fingers 33 of the lower lifting table 31 - to take over a partially processed stack 14 from the lower lifting table 31 ,

Auf diese Art und Weise können Stapel 14 in der Hebevorrichtung 30 vom unteren Hebetisch 31 angehoben werden, bis die oberste Platte in der Entnahmeposition angeordnet ist. Wenn ein Teil der Platten aus dem Stapel 14 entnommen worden, dieser also teilweise abgearbeitet worden ist, werden die Schwerter 34 des oberen Hebetisches 32 vorgeschoben und halten den teilweise abgearbeiteten Stapel 14, so dass der untere Hebetisch 31 abgesenkt werden kann und der inzwischen kleinere Stapel 14 vom oberen Hebetisch 32 übernommen wird und von diesem Hebetisch 32 schrittweise weiter angehoben werden kann.In this way, stacks 14 can be lifted in the lifting device 30 from the lower lifting table 31 until the uppermost plate is arranged in the removal position. If a part of the plates has been removed from the stack 14, so this has been partially processed, the swords 34 of the upper lifting table 32 are advanced and hold the partially processed stack 14, so that the lower lifting table 31 can be lowered and the now smaller stack 14 is taken from the upper lifting table 32 and can be further increased by this lifting table 32 gradually.

Durch das Zusammenspiel des unteren Hebetisches 31, und den in die Hebebahn vor- und zurückschiebbaren Schwertern 34 des oberen, ebenfalls nach oben anhebbaren Hebetisches 32 ist ein kontinuierliches Zuführen von Platten in die Entnahmeposition der Vereinzelungsstation 50 möglich.Due to the interplay of the lower lifting table 31, and the swivels 34, which can be pushed back and forth into the lifting track, of the upper lift table 32, which can also be lifted upwards, continuous feeding of plates into the removal position of the separating station 50 is possible.

Die Vereinzelungsstation 50 besitzt einen Plattenleger 51, der mit Hilfe von Saugköpfen 52, die über das Gehäuse 53 des Plattenlegers 51 mit Unterdruck beaufschlagt werden, die jeweils oberste Platte eines Stapels aufnimmt, anhebt, und auf die Förderelemente 61 ("Flügelgruppe") eines als Zwischenförderer dienenden Flügelförderbandes 60 ablegt. Die vertikalen Bewegungen des Plattenlegers 51 werden über ein Hebelgestänge 54 und Steuerkurven 55 oder Nocken gesteuert, so dass dieser so lange wie benötigt, nämlich bis die nächste Flügelgruppe 61 des Flügelförderbandes 60 in die Stellung für die Übernahme einer Platte vom Plattenleger 51 bewegt worden ist, angehoben bleibt. Die Abgabestelle, also die Stelle in der Platten einzeln auf ein einander gegenüberliegendes Paar aus Flügelgruppen 61 des als Zwischenförderer dienenden Flügelförderbandes 60 abgelegt werden, befindet sich im Bereich des Plattenlegers 51, so dass dieser nur vertikale Bewegungen ausführen braucht, wenn er eine Platte vom Stapel 14 aufnimmt und dann auf ein Paar aus Flügelgruppen 61 des Flügelförderbandes 60 ablegt.The singulator station 50 has a plate feeder 51, which lifts by means of suction heads 52, which are subjected to negative pressure via the housing 53 of the plate feeder 51, which receives each top plate of a stack, and on the conveying elements 61 ("wing group") as Intermediate conveyor serving wing conveyor belt 60 stores. The vertical movements of the plate feeder 51 are controlled by a lever link 54 and cam 55 or cam, so that this as long as needed, namely until the next set of wings 61 of the wing conveyor belt 60 has been moved to the position for the acquisition of a plate from the slicer 51, remains raised. The delivery point, so the location in the plates are placed individually on an opposite pair of groups of wings 61 serving as intermediate conveyor wing conveyor belt 60 is located in the area of the Plattenlegers 51 so that it needs to perform only vertical movements when he a plate from the stack 14 and then deposits on a pair of wing groups 61 of the wing conveyor 60.

Der Plattenleger 51 besitzt ein Gehäuse 53 mit mehreren, im Ausführungsbeispiel vier, Saugköpfen 52, die mit Unterdruck beaufschlagbar sind. Zum Abgeben einer vom Plattenleger 51 abgehobenen Platte auf das Flügelförderband 60 ist ein nockengesteuertes (Gestänge 56, Steuerscheibe 57) Ventil vorgesehen, das "Falschluft" in das Gehäuse 53 des Plattenleger 51 einlässt, so dass die von diesem gehaltene Platte auf ein Paar aus Flügelgruppen 61 des Flügelförderbandes 60, und zwar das Paar, das sich gerade unter dem Plattenleger 51 befindet, abfällt.The plate 51 has a housing 53 with a plurality, in the embodiment four, suction cups 52, which can be acted upon by negative pressure. For discharging a plate lifted from the plate-lifter 51 onto the wing conveyor 60, a cam-controlled valve (rod 56, control disc 57) is provided, which introduces "false air" into the housing 53 of the plate-restorer 51 so that the plate held by the latter is a pair of wing groups 61 of the wing conveyor belt 60, namely the pair, which is just below the plate 51, drops.

Um sicherzustellen, dass durch den Plattenleger 51 nur jeweils eine Platte vom Stapel 14 abgehoben wird, ist der Vereinzelungsstation 50 eine Vorrichtung zur Plattenvereinzelung 58 zugeordnet. Diese Plattenvereinzelung 58 besitzt einen vor- und zurückschiebbaren Finger 65, und einen mit Abstand gleich der Plattendicke unter dem Finger 65 angeordnetten Teller 66, der ebenfalls vor- und zurückschiebbar ist (vgl. Fig. 9.1, 9.2).In order to ensure that only one plate is lifted from the stack 14 by the slab 51, the separating station 50 is assigned a device for plate separation 58. This plate separation 58 has a forward and zurückschiebbaren finger 65, and arranged at a distance equal to the plate thickness under the finger 65 plate 66, which is also pushed back and forth (see. Fig. 9.1, 9.2) ,

Ein Stapel 14 wird entweder vom unteren Hubtisch 31 oder vom oberen Hubtisch 32 so weit angehoben, dass die oberste Platte von unten her an dem vorgeschobenen Finger 65 der Plattenvereinzelung 58 anliegt. Sobald dies geschehen ist, wird der Teller 66 vorgeschoben und dringt in den Spalt zwischen der obersten und der nächst unteren Platte ein, so dass die obere Platte von der darunter befindlichen Platte sicher getrennt wird und vom Plattenleger 51 mit Hilfe seiner Saugköpfe 52 abgehoben und auf das Flügelförderband 60 abgelegt werden kann.A stack 14 is raised either from the lower lift table 31 or from the upper lift table 32 so far that the uppermost plate rests against the advanced finger 65 of the plate separation 58 from below. Once this is done, the plate 66 is advanced and penetrates into the gap between the uppermost and the next lower plate, so that the upper plate is securely separated from the plate underneath and lifted off the plate 51 by means of its suction cups 52 and on the wing conveyor belt 60 can be stored.

Vom Flügelförderband 60 werden Platten einzeln in Fig. 1 nach rechts bewegt.From the wing conveyor 60 plates are individually in Fig. 1 moved to the right.

Das Flügelförderband 60 besitzt zwei um je zwei Umlenkräder mit lotrechtten Achsen umlaufende Endlosketten 62, von welchen mit Abstand voneinander Auflageflügel 61 für Platten ("Flügelgruppen") von den Endlosketten 62 in den Raum zwischen den Endlosketten 62 abstehend, vorgesehen sind. In jeder Flügelgruppe 61 sind an ihren in Bewegungsrichtung hinteren Ende Anschlagwinkel 63 für den sicheren Transport von Platten vorgesehen. In dem Bereich, in dem sich die Trume der Endlosketten 62 in Fig. 1 nach rechts, also in Förderrichtung des Flügelförderbandes 60 bewegen, liegen einander zwei Flügelgruppen 61 gegenüber und bilden ein Paar aus Flügelgruppen 61, auf denen aufliegend eine Platte von der Vereinzelungsstation 50 weg transportiert wird (vgl. Fig. 5 und 6). Im Bereich nach dem Plattenleger 51 ist dem Flügelförderband 60 eine Vorrichtung zum Erkennen von (unerwünschten) Doppelplatten (zwei aufeinanderliegende Platten) zugeordnet. Soferne eine "Doppelplatte" festgestellt wird, wird sichergestellt, dass diese Platten am Ende des Flügelförderbandes 60 in einen Auswurfschacht 64 abgeworfen wird. Dies kann beispielsweise dadurch erfolgen, dass die erste Vakuumkammer 73 eines nachgeschalteten Vakuumförderbandes 70 nicht mit Unterdruck beaufschlagt wird, so dass das Vakuumförderband 70 vom Flügelförderband 60 herangeförderte "Doppelplatten" nicht aufnehmen kann. Alternativ oder zusätzlich kann im Bereich des als abgabeseitigen Endes des Flügelförderbandes 60 eine Hebevorrichtung 76 vorgesehen sein, die einzelne Platten zum aufgabeseitigen Ende des Vakuumförderbandes 70 anhebt, so dass diese vom Vakuumförderband 70 aufgenommen werden, oder bei erkannten "Doppelplatten" nicht aktiviert wird, so dass Doppelplatten in den Auswurfschacht 64 fallen.The wing conveyor belt 60 has two circulating about two pulleys with vertical axes endless chains 62, of which at a distance from each other support wings 61 for plates ("groups of wings") from the endless chains 62 in the space between the endless chains 62 projecting, are provided. In each wing group 61 are provided at their rear end in the direction of travel stop bracket 63 for the safe transport of plates. In the area in which the strands of the endless chains 62 in Fig. 1 move to the right, ie in the conveying direction of the wing conveyor belt 60, two wing groups 61 are opposed to each other and form a pair of wing groups 61, on which a plate is transported lying on the separation station 50 away (see. Fig. 5 and 6 ). In the area after the plate 51, the wing conveyor 60 is associated with a device for detecting (unwanted) double plates (two superimposed plates). If a "double plate" is detected, it is ensured that these plates at the end of the wing conveyor belt 60 is dropped into a discharge chute 64. This can be done, for example, by the fact that the first vacuum chamber 73 of a downstream vacuum conveyor belt 70 is not subjected to negative pressure, so that the vacuum conveyor belt 70 can not pick up the "double plates" conveyed by the wing conveyor belt 60. Alternatively or additionally, a lifting device 76 may be provided in the region of the discharge side end of the vane conveyor belt 60 lifting individual plates to the discharge side end of the vacuum conveyor belt 70 so that they are picked up by the vacuum conveyor belt 70 or not activated on detected "double plates" that double plates fall into the discharge chute 64.

Das Vakuumförderband 70 ist mit Überlappung zum abgabeseitigen Ende des Flügelförderbandes 61 vorgesehen. Das Vakuumförderband 70 besitzt einen Endlosgurt 71 mit mehreren in ihm angeordneten Lochgruppen 72 und mehreren, dem unteren Trum des Gurtes 71, das sich in Fig. 1 von links nach rechts bewegt, zugeordneten Vakuumkammern 73, 74, 75. Die Vakuumkammern 73, 74, 75 sind einzeln und unabhängig voneinander mit Unterdruck beaufschlagbar. Das Vakuumförderband 70 übernimmt, gegebenenfalls unerstützt durch die Hebeeinrichtung 76 vom abgabeseitigen Ende des Flügelförderbandes 60 vereinzelte Platten und transportiert diese in Fig. 1 nach rechts. Die Bewegungen des Flügelförderbandes 60 und des Vakuumförderbandes 70 sind so aufeinander abgestimmt, das immer dann eine Platte auf einem Paar aus Flügelgruppen 61 aufliegend am Ende des Flügelförderbandes 60 ankommt, wenn sich eine Lochgruppe 72 des Endlosgurtes 71 des Vakuumförderbandes 70 am abgabeseitigen Ende des Flügelförderbandes 60 befindet.The vacuum conveyor belt 70 is provided with overlap to the discharge-side end of the vane conveyor belt 61. The vacuum conveyor belt 70 has an endless belt 71 with a plurality of hole groups 72 arranged therein and a plurality, the lower run of the belt 71, which extends in Fig. 1 moved from left to right, associated vacuum chambers 73, 74, 75. The vacuum chambers 73, 74, 75 are individually and independently acted upon by negative pressure. The vacuum conveyor belt 70 takes over, if necessary unsupported by the lifting device 76 from the discharge end of the wing conveyor belt 60 separated plates and transports them in Fig. 1 to the right. The movements of the wing conveyor belt 60 and the vacuum conveyor belt 70 are coordinated so that a plate on a pair of groups of wings 61 resting on the end of the wing conveyor belt 60 arrives when a group of holes 72 of the endless belt 71 of the vacuum conveyor belt 70 at the discharge end of the wing conveyor 60th located.

Das Vakuumförderband 70 kann für Wartungsarbeiten oder für das Beheben von Störungen in die in Fig. 2 strichliert eingezeichnete Stellung hochgeschwenkt werden.The vacuum conveyor belt 70 may be used for maintenance or for troubleshooting in the in Fig. 2 dashed position drawn up.

Dem unteren Trum des Gurtes 71 des Vakuumförderbandes 70 ist im Ausführungsbeispiel eine Einrichtung 80 zum Bürsten von Kontaktfahnen von Batterie- oder Akkumulatorplatten zugeordnet. Im Bereich diesel Einrichtung 80 sind dem unteren Trum des Vakuumförderbandes 70 zugeordnete Klemmrollen 81 vorgesehen, welche Klemmrollen 81 dadurch, dass sie Platten von unten gegen den Endlosgurt 71 drücken, sicherstellen, dass die Platten beim Bürsten ihrer Fahnen keine unerwünschten Bewegungen ausführen und sicher weiterbewegt werden.The lower run of the belt 71 of the vacuum conveyor belt 70 is associated with a device 80 for brushing tabs of battery or Akkumulatorplatten in the embodiment. In the area of diesel device 80 are associated with the lower run of the vacuum conveyor belt 70 Clamping rollers 81 are provided, which pinch rollers 81, by pressing plates from below against the endless belt 71, ensure that the plates perform no unwanted movements when brushing their flags and safely moved on.

Dem abgabeseitigen Ende des Vakuumförderbandes 70 ist eine Hauptförderbahn 90 für den Abtransport vereinzelter Platten, wie Batterie- oder Akkumulatorplatten, zugeordnet. Die im Bereich der Hauptförderbahn 90 vorgesehene Vakuumkammer 75 des Vakuumförderbandes 70 ist belüftbar, so dass in ihr Vakuum aufgehoben und die im Vakuumband 70 vorgesehenen Lochgruppen 72 in diesem Bereich nicht mit Unterdruck beaufschlagt werden, sodass eine Platte, die vom Vakuumförderband 70 an dessen unterem Trum durch den Unterdruck gehalten über der Hauptförderbahn 9.0 angekommen ist, losgelassen wird und auf die Hauptförderbahn 90 abfällt.The discharge-side end of the vacuum conveyor belt 70 is a main conveyor track 90 for the removal of individual plates, such as battery or Akkumulatorplatten assigned. The provided in the main conveyor belt 90 vacuum chamber 75 of the vacuum conveyor belt 70 is ventilated so that lifted in their vacuum and provided in the vacuum belt 70 hole groups 72 are not subjected to negative pressure in this area, so that a plate of the vacuum conveyor belt 70 at the lower strand held by the negative pressure above the main conveyor 9.0 arrived, is released and falls on the main conveyor track 90.

Die Hauptförderbahn 90 kann eine Förderbahn zu einer Vorrichtung zum Eintaschen von Batterie- oder Akkumulatorplatten sein, wie sie beispielsweise aus der US 6 499 208 A oder der US 6 670 072 A bekannt sind.The main conveyor track 90 may be a conveyor to a device for bagging battery or Akkumulatorplatten, as for example from the US Pat. No. 6,499,208 or the US Pat. No. 6,670,072 are known.
