Description

Die Erfindung betrifft einen Ausleger für eine flächige Bedruckstoffe verarbeitende Maschine, insbesondere eine Bogen verarbeitende Druckmaschine, mit einer Stapelstation, in welcher zu dieser in einer Verarbeitungsrichtung beförderte Bogen gestapelt werden, einer bezüglich der Verarbeitungsrichtung stromaufwärts gegenüber der Stapelstation gelegenen Bereitstellungsstation mit einer in einer Seitenwand vorgesehenen Einschuböffnung zum Einführen einer Stapelunterlage in die Bereitstellungsstation und einem Förderer, mittels welchem die in die Bereitstellungsstation eingeführte Stapelunterlage in die Stapelstation verbringbar ist sowie eine mit dem Ausleger ausgestattete flächige Bedruckstoffe verarbeitende Maschine, insbesondere eine Druckmaschine.The invention relates to a boom for a sheet-fed printing machine, in particular a sheet-fed printing press, with a stacking station, in which are stacked to this in a processing direction conveyed sheet, a processing direction upstream of the stacking station located with a provision provided in a side wall Insertion opening for introducing a stack underlay into the supply station and a conveyor, by means of which the stack support introduced into the supply station can be brought into the stacking station and a machine equipped with the delivery area, in particular a printing press.

Ein Ausleger der genannten Art ist aus der Druckschrift DE 196 12 294 C2 bekannt. Diese offenbart einen Förderer, mittels welchem Stapelunterlagen unterschiedlicher Art von der genannten Bereitstellungsstation in die genannte Stapelstation transportierbar sind. Insoweit es sich bei diesen Stapelunterlagen um solche in Form eines Rechens oder eines Schwebetisches handelt, wird zumindest bei ein und demselben von der Maschine abzuarbeitenden Auftrag ein und dieselbe Stapelunterlage gegebenenfalls mehrfach zwischen der Bereitstellungsstation und der Stapelstation hin und her verfahren. Eine notwendige Umrüstung des Auslegers auf eine andere Stapelunterlage ist dabei allenfalls bei einem Auftragswechsel erforderlich, und auch nur dann, wenn beispielsweise im Falle einer in Form eines Rechens vorgesehenen Stapelunterlage diese für den Fall der Stapelbildung auf nicht mit Nuten versehenen Paletten ungeeignet ist, um einen Stapelwechsel während des Fortdruckes durchzuführen, so dass der Ausleger auf eine Stapelunterlage in Form des genannten Schwebetisches umgerüstet werden muss. Eine montierte Stapelunterlage in Form des Rechens oder des Schwebetisches verbleibt also in der Regel über einen relativ großen Zeitraum im Einsatz, da beim Stapelwechsel unter Verwendung eines Rechens oder eines Schwebetisches als eine einen Hilfsstapelträger bildende Stapelunterlage je nach Art der verwendeten Palette der Hilfsstapelträger von Fall zu Fall immer ein und derselbe ist.A boom of the type mentioned is known from the document DE 196 12 294 C2. This discloses a conveyor, by means of which stacking documents of different types of the said delivery station in said stacking station are transportable. Insofar as these stacking documents are those in the form of a rake or a levitation table, one and the same stacker is, if appropriate, repeatedly moved back and forth between the provisioning station and the stacking station, at least for one and the same order to be processed by the machine. A necessary conversion of the boom to another stack underlay is at most necessary for a job change, and only if, for example, in the case of a stack provided in the form of a rake this is unsuitable for the case of stacking on non-grooved pallets to a Stack change during the Performing printing so that the boom must be converted to a stack underlay in the form of said floating table. A mounted stack support in the form of the rake or the levitation table thus remains in use for a relatively long period of time, as in the stack change using a rake or a levitation table as an auxiliary stack carrier forming stack support depending on the type of pallet used, the auxiliary stack carrier by case Case is always one and the same.

Im Falle einer Hürdenbildung ist jedoch für jeden zu bildenden Teilstapel eine weitere Stapelunterlage in Form eines Hürdenbrettes erforderlich.In the case of a hurdle formation, however, a further stack underlay in the form of a hurdle board is required for each partial stack to be formed.

Eine Vorrichtung zur mechanisierten, von einer Bereitstellungsstation ausgehenden Beschickung einer Stapelstation mit verlorenen Stapelunterlagen, wie insbesondere mit Hürdenbrettern, ist aus der Druckschrift DE 43 44 361 C2 bekannt. In der darin offenbarten Bereitstellungsstation ist eine Mehrzahl von aufeinandergeschichteten Stapelunterlagen in einem Magazin bevorratet, aus welchem die jeweils unterste mittels eines zwischen der Bereitstellungsstation und der Stapelstation hin und her verfahrbaren und mit Mitnehmern ausgestatteten Rechens in die Stapelstation transportierbar ist. Angaben über eine Befüllung des Magazins sind der genannten Druckschrift nicht entnehmbar. Es ist jedoch vorstellbar, dass das Magazin vor Beginn eines Druckauftrags durch manuelles Einlegen der Stapelunterlagen aufgefüllt wird. Die bekannte Vorrichtung ist damit durchaus vorteilhaft zur Hürdenauslage einsetzbar solange ein Druckauftrag eine gewisse Auflagenhöhe und damit eine gewisse Anzahl von erforderlichen Hürdenbrettern nicht überschreitet.A device for mechanized, emanating from a staging station loading a stacking station with lost stacking documents, in particular with hurdles, is known from the document DE 43 44 361 C2. In the staging station disclosed therein, a plurality of stacked stacking pads are stored in a magazine from which each of the lowermost by means of a between the staging station and the stacking station reciprocally movable and equipped with carriers rake in the stacking station is transportable. Information about a filling of the magazine can not be found in the cited document. However, it is conceivable that the magazine is filled by manually inserting the stack documents before the start of a print job. The known device is therefore quite advantageous for hurdles deployable as long as a print job does not exceed a certain amount of circulation and thus a certain number of required hurdles.

Der in der eingangs genannten Druckschrift DE 196 12 294 C2 offenbarte Ausleger ist für den Fall einer Überschreitung einer gewissen Auflagenhöhe zwar grundsätzlich geeignet. Es verbleibt hierbei jedoch die Schwierigkeit des Einbringens entsprechender Stapelunterlagen in die Bereitstellungsstation. Der in der letztgenannten Druckschrift offenbarte Ausleger bietet hierzu lediglich eine schlitzförmige seitliche Öffnung einer Seitenwand des Auslegers an, durch welche jeweils eine Stapelunterlage in Form eines Hürdenbrettes in die Bereitstellungsstation verbracht und an der Förderer übergeben werden soll, der zur Aufnahme der Stapelunterlage lediglich Rahmenschenkel aufweist, die in der Nachbarschaft einer jeweiligen Seitenwand angeordnet sind. Das Einbringen einer Stapelunterlage durch die besagte Einschuböffnung erweist sich damit als äußerst schwierig.The disclosed in the aforementioned document DE 196 12 294 C2 boom is in principle suitable for the case of exceeding a certain amount of circulation. However, this leaves the difficulty of introducing appropriate stacking pads into the staging station. For this purpose, the boom disclosed in the last-mentioned publication offers only a slot-shaped lateral opening of a side wall of the jib, through which a stacking support in the form of a hurdle board is to be transferred to the delivery station and transferred to the conveyor, which has only frame legs for receiving the stack support. which are arranged in the vicinity of a respective side wall. The introduction of a stack underlay through said insertion opening thus proves to be extremely difficult.

Der Erfindung liegt die Aufgabe zugrunde, den eingangs genannten Ausleger so auszubilden, dass das Einbringen von Stapelunterlagen in die Bereitstellungsstation erleichtert wird und in kürzester Zeit durchführbar ist.The invention has for its object to form the aforementioned boom so that the introduction of stacking pads is facilitated in the staging and can be carried out in a very short time.

Zur Lösung dieser Aufgabe ist in der Bereitstellungsstation ein Stapelunterlagenträger mit einem zwischen einem ersten Niveau und einem gegenüber diesem tieferen zweiten Niveau verstellbaren Auflager angeordnet, welches auf seinem ersten Niveau die in die Bereitstellungsstation eingeführte Stapelunterlage aufnimmt und unter Verstellung in Richtung auf das zweite Niveau an den Förderer übergibt.To solve this problem, a stack underlay carrier is arranged in the staging station with a support adjustable between a first level and a lower second level, which receives at its first level the stack underlay introduced into the staging station and under adjustment towards the second level Sponsor hands over.

Bei dieser Ausgestaltung ist eine jeweils durch die Einschuböffnung in die Bereitstellungsstation eingeführte Stapelunterlage auf den Stapelunterlagenträger aufschiebbar, welcher die Stapelunterlage sodann in erforderlicher Weise derart ausrichtet, dass nach erfolgtem Einschieben der Stapelunterlage diese unter Absenkung des Stapelunterlagenträgers an den Förderer übergeben wird, nachdem die Stapelunterlage durch die besagte Ausrichtung in eine waagerechte Lage verbracht wurde.In this embodiment, each inserted through the insertion opening in the staging station stacking support is pushed onto the stack support base, which then aligns the stack support in the required manner so that after the successful insertion of the Stacking pad this is transferred to the conveyor under lowering of the stack base support, after the stack support has been spent by the said alignment in a horizontal position.

Zwischen den beiden Förderketten 6 erstrecken sich von diesen getragene Greifersysteme 9 mit Greifern 9.1, welche Lücken zwischen den am Druckzylinder 2.1 angeordneten Greifern durchfahren und dabei einen jeweiligen Bogen 3 unter Erfassen des genannten Greiferrandes am vorauseilenden Ende des Bogens 3 unmittelbar vor dem Öffnen der am Druckzylinder 2.1 angeordneten Greifer übernehmen, ihn über eine Bogenleitvorrichtung 10 hinweg zu einer Bogenbremse 11 transportieren und sich dort zur Übergabe des Bogens 3 an die Bogenbremse 11 öffnen. Diese vermittelt den Bogen eine gegenüber der Verarbeitungsgeschwindigkeit verringerte Ablagegeschwindigkeit und gibt sie nach Erreichen derselben ihrerseits frei, so dass ein jeweiliger nunmehr verlangsamter Bogen 3 in einer Stapelstation 14 schließlich auf Vorderkantenanschläge 12 auftrifft und unter Ausrichtung an diesen und an diesen gegenüberliegenden, quer zur Verarbeitungsrichtung schwenkbaren Hinterkantenanschlägen 13 gemeinsam mit vorausgegangenen und/oder nachfolgenden Bogen 3 einen Stapel 14.1 bildet, der mittels eines Hubwerkes in dem Maße absenkbar ist, wie der Stapel 14.1 anwächst. Von dem Hubwerk sind in Fig. 1 lediglich eine den Stapel 14.1 tragende Plattform 15 und diese tragende, strichpunktiert angedeutete Hubketten 16 wiedergegeben.The section of a sheet-fed rotary printing press illustrated in FIG. 1 comprises a delivery device 1 following a last processing station. Such a processing station may be a printing unit or a post-treatment unit, such as a coating unit. In the present example, the last processing station is an offset printing unit 2 with a printing cylinder 2.1. This leads a respective sheet 3 in a direction indicated by the direction of arrow 5 processing direction through a pressure gap between the impression cylinder 2.1 and a cooperating blanket cylinder 2.2 and then passes it to a chain conveyor 4 under opening arranged on the impression cylinder 2.1, for detecting the sheet 3 at a Gripper edge provided on the leading end of the sheet grippers. The chain conveyor 4 comprises two conveyor chains 6, of which a respective one operatively rotates along a respective side wall of the chain jib 1. A respective conveyor chain 6 wraps around each one of two synchronously driven drive sprockets 7, whose axes of rotation are aligned with each other, and is guided in the present example via one Umlenkkettenrad 8 located downstream of the drive sprockets 7 downstream with respect to the processing direction. Between both conveyor chains 6 extend from these supported gripper systems 9 with grippers 9.1, which pass through gaps between the arranged on the printing cylinder 2.1 grippers and arranged a respective sheet 3 under detection of said gripper edge at the leading end of the sheet 3 immediately before the opening of the printing cylinder 2.1 Take over gripper, transport him across a sheet guiding device 10 to a sheet brake 11 and there open to the transfer of the sheet 3 to the sheet brake 11. This gives the sheet a reduced speed compared to the processing speed and releases them after reaching the same turn, so that a respective now slowed sheet 3 in a stacking station 14 finally hits leading edge stops 12 and in alignment with these and these opposite, pivotable transversely to the processing direction Trailing edge stops 13 together with previous and / or subsequent sheet 3 forms a stack 14.1 which can be lowered by means of a hoist to the extent that the stack grows 14.1. Of the hoist in Fig. 1, only one stack 14.1 supporting platform 15 and this supporting, dash-dotted lines indicated lifting chains 16 are shown.

Die Förderketten 6 sind entlang ihrer Wege zwischen den Antriebskettenrädern 7 einerseits und den Umlenkkettenrädern 8 andererseits mittels Kettenführungsschienen geführt, welche somit die Kettenbahnen der Kettentrume bestimmen. Im vorliegenden Beispiel werden die Bogen 3 von dem in Fig. 1 unteren Kettentrum transportiert. Dem von diesem durchlaufenen Abschnitt der Kettenbahn folgt eine diesem zugewandte, an der Bogenleitvorrichtung 10 ausgebildete Bogenleitfläche 17. Zwischen dieser und dem jeweils darüber hinweggeführten Bogen 3 ist bevorzugt betriebsmäßig ein Tragluftpolster ausgebildet. Hierzu ist die Bogenleitvorrichtung 10 mit in die Bogenleitfläche 17 mündenden hier nicht dargestellten Blasluftdüsen ausgestattet.The conveyor chains 6 are guided along their paths between the drive sprockets 7 on the one hand and the Umlenkkettenrädern 8 on the other hand by means of chain guide rails, which thus determine the chain tracks of the chain. In the present example, the sheets 3 are transported by the lower in Fig. 1 chain. The traversed by this section of the chain track follows a facing this, formed on the sheet guiding device 10 sheet guide surface 17. Between this and the respective over-carried sheet 3 is preferably operationally a supporting air cushion is formed. For this purpose, the sheet guiding device 10 in the Sheet guide 17 equipped here not shown Blasluftdüsen.

Um ein gegenseitiges Verkleben der bedruckten Bogen 3 im Stapel 14.1 zu verhindern, sind auf dem Weg der Bogen 3 von den Antriebskettenrädern 7 zur Bogenbremse 11 ein Trockner 19 und eine Bestäubungsvorrichtung 20 vorgesehen.In order to prevent mutual sticking of the printed sheets 3 in the stack 14.1, a dryer 19 and a dusting device 20 are provided on the way the sheet 3 of the drive sprockets 7 to the sheet brake 11.

Zur Vermeidung einer übermäßigen Erwärmung der Bogenleitfläche 17 durch den Trockner 19 ist in die Bogenleitvorrichtung 10 ein Kühlmittelkreislauf integriert, der in Fig. 1 durch eine Kühlmittelwanne 23 angedeutet ist.To avoid excessive heating of the sheet guide surface 17 through the dryer 19, a coolant circuit is integrated into the sheet guiding device 10, which is indicated in Fig. 1 by a coolant trough 23.

Die Fig. 2 zeigt in einer Draufsicht eine benachbart zur Stapelstation 14, hier bevorzugt bezüglich der Verarbeitungsrichtung stromaufwärts gegenüber der Stapelstation 14 vorgesehene Bereitstellungsstation 24, in deren Bereich, wie in Fig. 1 erkennbar, in einer Seitenwand 1.1 des Auslegers 1 eine Einschuböffnung 25 zum Einführen einer Stapelunterlage 26 in die Bereitstellungsstation 24 vorgesehen ist. Zwischen der Stapelstation 14 und der Bereitstellungsstation 24 besteht eine funktionelle Anbindung über einen im weiteren Verlauf erläuterten Förderer, mittels welchem die in die Bereitstellungsstation 24 eingeführte Stapelunterlage 26 in die Stapelstation 14 verbringbar ist.FIG. 2 shows a plan view of a supply station 24 adjacent to the stacking station 14, preferably here upstream of the stacking station 14 with respect to the processing direction, in the area of which, as can be seen in FIG. 1, in a side wall 1.1 of the jib 1, an insertion opening 25 Inserting a stack support 26 is provided in the delivery station 24. There is a functional connection between the stacking station 14 and the provisioning station 24 via a conveyor explained below, by means of which the stack support 26 introduced into the provisioning station 24 can be brought into the stacking station 14.

Über die Stapelstation 14 und die Bereitstellungsstation 24 hinweg erstreckt sich ein heb- und senkbarer rechteckiger Rahmen 27 mit seitlichen, im Bereich einer jeweiligen der Seitenwände 1.1 und 1.2 angeordneten Rahmenschenkeln 27.1 und 27.2, die an deren jeweiligen Enden mittels einer Traverse 27.3 und 27.4 miteinander verbunden sind (siehe Fig. 5). Die Rahmenschenkel 27.1 und 27.2 tragen einen entlang dieser zwischen der Bereitstellungsstation 24 und der Stapelstation 14 hin und her verschiebbaren, zur Aufnahme einer Stapelunterlage 26 ausgebildeten U-förmigen Schlitten 28 mit Schenkeln 28.1 und 28.2 und einem diese verbindenden, in Fig. 3 erkennbaren, der Stapelstation 14 abgewandten Steg 28.3. Die Rahmenschenkel 27.1 und 27.2 sind als Hohlprofile ausgebildet, in welchen Linearantriebe untergebracht sind. Die Schenkel 28.1 und 28.2 des Schlittens 28 sind über die Rahmenschenkel 27.1 und 27.2 durchgreifende Mitnehmer mit den Linearantrieben verbunden und in unmittelbarer Nachbarschaft zu den Rahmenschenkeln 27.1 und 27.2 angeordnet.A lifting and lowering rectangular frame 27 extends beyond the stacking station 14 and the provisioning station 24 with lateral frame legs 27.1 and 27.2 arranged in the region of a respective one of the side walls 1.1 and 1.2, which are connected together at their respective ends by means of a traverse 27.3 and 27.4 are (see Fig. 5). The Frame legs 27.1 and 27.2 carry a along this between the staging station 24 and the stacking station 14 displaced, designed to receive a stack base 26 U-shaped carriage 28 with legs 28.1 and 28.2 and connecting them, visible in Fig. 3, the stacking station 14 facing away from the bridge 28.3. The frame legs 27.1 and 27.2 are formed as hollow profiles, in which linear actuators are housed. The legs 28.1 and 28.2 of the carriage 28 are connected via the frame legs 27.1 and 27.2 cross-driver with the linear drives and arranged in the immediate vicinity of the frame legs 27.1 and 27.2.

Der Rahmen 27 mit den darin integrierten Linearantrieben und der Schlitten 28 bilden einen Förderer, mittels welchem eine jeweilige in die Bereitstellungsstation 24 eingeführte, auf dem Schlitten 28 abgelegte Stapelunterlage 26 in die Stapelstation 14 verbringbar ist.The frame 27 with the linear drives and the carriages 28 integrated therein form a conveyor by means of which a respective stacking support 26 introduced into the provisioning station 24 and placed on the carriage 28 can be brought into the stacking station 14.

Zur Realisierung des genannten Förderers im Einzelnen wird bevorzugt auf die in DE 196 12 294 C2 in Bezug auf das dortige Hilfsstapelaufnahmeelement und den dortigen Hilfsstapelrahmen dargelegte Ausgestaltung zurückgegriffen.For the realization of said conveyor in detail, reference is preferably made to the embodiment set forth in DE 196 12 294 C2 with respect to the local auxiliary pile receiving element and the auxiliary pile stack there.

Der Schlitten 28 ist zur Aufnahme einer jeweiligen Stapelunterlage 26 ausgebildet. Hierzu sind, wie in Fig. 3 erkennbar, die Schenkel 28.1 und 28.2 des Schlittens 28 jeweils derartig mit einem L-förmigen Querschnitt versehen, dass ein jeweiliges L einen jeweiligen seitlichen Randbereich einer Stapelunterlage 26 unterfängt und einen Anschlag für eine jeweilige seitliche Stirnseite der Stapelunterlage 26 ausbildet, die hier in Form eines Hürdenbrettes vorliegt.The carriage 28 is designed to receive a respective stack support 26. For this purpose, as can be seen in FIG. 3, the legs 28.1 and 28.2 of the carriage 28 are each provided with an L-shaped cross-section such that a respective L captures a respective lateral edge region of a stack support 26 and a stop for a respective lateral end side of the stack support 26, which is here in the form of a hurdle board.

In der Bereitstellungsstation 24 ist ein Stapelunterlagenträger 29 mit einem zwischen einem ersten Niveau und einem gegenüber diesem tieferen zweiten Niveau verstellbaren Auflager 29.1 angeordnet. Der Stapelunterlagenträger 29 ist, wie insbesondere in Fig. 3 erkennbar, in eine an der Unterseite des Rahmens 27 angeordnete und von diesem getragene Wanne 30 eingesetzt und an einem Wannenboden 30.1 der Wanne 30 befestigt und er besitzt die Form eines Hubtisches mit einer am Auflager 29.1 ausgebildeten Tischfläche 29.1 und eines das Auflager 29.1 tragenden, mittels eines Stellzylinders 29.2 betätigbaren Hubwerkes 29.3, hier in Form eines Gelenkgetriebes mit einer Schwenkhebelanordnung.In the staging station 24, a stack base support 29 is arranged with a support 29.1 adjustable between a first level and a second level lower than this second level. The stack base support 29 is, as can be seen in particular in Fig. 3, inserted into a arranged on the underside of the frame 27 and carried by this tray 30 and attached to a tub bottom 30.1 of the tub 30 and he has the shape of a lifting table with a support 29.1 trained table surface 29.1 and a bearing 29.1 bearing, actuated by means of an actuating cylinder 29.2 hoist 29.3, here in the form of a linkage with a pivot lever assembly.

Die Fig. 4 zeigt den Hubtisch in einer aus dem Ausleger 1 herausgelösten Darstellung, wobei das Hubwerk 29.3 in einer Stellung wiedergegeben ist, in welcher sich das Auflager 29.1 auf dessen tieferen zweiten Niveau befindet. Das Auflager 29.1 ist sowohl in dessen Lage auf dem zweiten als auch in dessen Lage auf dem höheren ersten Niveau dargestellt.Fig. 4 shows the lifting table in a detached from the boom 1 representation, the hoist 29.3 is shown in a position in which the support 29.1 is at its lower second level. The support 29.1 is shown both in its position on the second and in its position at the higher first level.

Wie der Fig. 3 weiterhin entnehmbar, ist an der die bereits erwähnte Einschuböffnung 25 aufweisenden Seitenwand 1.1 des Auslegers 1 in vorteilhafter Ausgestaltung eine Rampe 31 angeordnet. Diese stützt während einer Anfangsphase der hier manuellen Beschickung der Bereitstellungsstation 24 mit einer Stapelunterlage 26 die letztere ab und erbringt somit eine weitere Erleichterung beim Einbringen derselben in die Bereitstellungsstation 24.As shown in FIG. 3 further removed, a ramp 31 is arranged on the already mentioned insertion opening 25 having side wall 1.1 of the jib 1 in an advantageous embodiment. This supports the latter during an initial phase of manual loading of the staging station 24 with a stacking pad 26, thus providing further ease of introduction to the staging station 24.

Der die Wanne 30 und somit den Stapelunterlagenträger 29 tragende und, wie bereits erwähnt, heb- und senkbare Rahmen 27 nimmt wenigstens während des Einschiebens der Stapelunterlage 26 durch die Einschuböffnung 25 in die Bereitstellungsstation 24 eine derartige Höhenlage ein, dass die Stapelunterlage 26 unter Einschieben in die Bereitstellungsstation 24 an die Tischfläche 29.1' des mittels des Hubwerkes 29 auf dem ersten Niveau gehaltenen Auflagers 29.1 übergebbar ist. Das von dem Auflager 29.1, genauer von dessen Tischfläche 29.1 ' eingenommene erste Niveau liegt hierbei oberhalb der Schenkel 28.1 und 28.2 des Schlittens 28, zumindest jedoch oberhalb derjenigen durch den L-förmigen Querschnitt von dessen Schenkeln 28.1 und 28.2 gebildeten Stützflächen, welche zum Unterfangen der seitlichen Randbereiche der Stapelunterlage 26 vorgesehen sind. Im übrigen ist dieses erste Niveau derart mit den Lagen der Einschuböffnung 25 und der Rampe 31 abgestimmt, dass ein ungehindertes Einführen der Stapelunterlage 26 in die Bereitstellungsstation 24 möglich ist.The frame 30, which supports the tray 30 and thus supports the stack support 29 and, as already mentioned, can be raised and lowered frame 27, at least during the insertion of the stack support 26 through the insertion opening 25 into the frame Provisioning station 24 such an altitude that the stack support 26 can be transferred under insertion into the provisioning station 24 to the table surface 29.1 'of the held by means of the hoist 29 at the first level support 29.1. The first level occupied by the support 29.1, more precisely by its table surface 29.1 ', lies above the legs 28.1 and 28.2 of the carriage 28, but at least above those support surfaces formed by the L-shaped cross section of its legs 28.1 and 28.2, which are used to carry out the operation lateral edge regions of the stack support 26 are provided. Moreover, this first level is matched with the positions of the insertion opening 25 and the ramp 31 in such a way that unimpeded insertion of the stack support 26 into the delivery station 24 is possible.

Zum lagegerechten Positionieren der Stapelunterlage 26 auf dem Auflager 29.1 des Stapelunterlagenträgers 29 während der Übergabe der Stapelunterlage 26 an die Tischfläche 29.1' des Auflagers 29.1 sind an dem Rahmen 27 die in Einschubrichtung seitlichen Stirnflächen der Stapelunterlage 26 führende Führungsschienen 32 und 33 und eine Anschlagschiene 34 angeordnet.For positionally correct positioning of the stack support 26 on the support 29.1 of the stack support 29 during the transfer of the stack support 26 to the table surface 29.1 'of the support 29.1 are on the frame 27 in the insertion direction lateral end faces of the stack support 26 leading guide rails 32 and 33 and a stop rail 34 is arranged ,

Mittels eines Rückhubes der zum Positionieren der Stapelunterlage 26 auf dem Auflager 29.1 ausgefahrenen Kolbenstange des Stellzylinder 29.2 wird das Auflager 29.1 von seinem ersten Niveau auf sein tiefer gelegenes zweites Niveau abgesenkt. Dieses zweite Niveau ist derart definiert, dass die zuvor auf der Tischfläche 29.1' abgelegte Stapelunterlage 26 während des Absenkens des Auflagers 29.1 seitens der Schenkel 28.1 und 28.2 des Schlittens 28 von der Tischfläche 29.1' abgehoben und damit an den den Schlitten 28 umfassenden Förderer übergeben wird.By means of a return stroke of the piston for positioning the stack support 26 on the support 29.1 extended piston rod of the actuating cylinder 29.2 29.1 the support is lowered from its first level to its lower second level. This second level is defined such that the stack support 26 previously deposited on the table surface 29.1 'is lifted off the table surface 29.1' during the lowering of the support 29.1 by the legs 28.1 and 28.2 of the carriage 28 and thus transferred to the conveyor comprising the carriage 28 ,

Eine weitere Erleichterung ergibt sich mit einem in weiterer Ausgestaltung vorgesehenen weiteren Förderer 35, mittels welchem die Stapelunterlage 26 dem Stapelunterlagenträger 29 zuführbar ist. Dieser weitere Förderer 35 umfasst bevorzugt eine mit einem Antrieb 35.1 verbundene Förderwalze 35.2, wobei der Antrieb 35.1, wie am Beispiel gemäß Fig. 5 gezeigt, vorteilhafterweise innerhalb der Förderwalze 35.2 angeordnet ist. Bei diesem Beispiel stellt die Förderwalze 35.2 einen Außenring eines als Außenringläufer ausgebildeten Elektromotors dar. Die Förderwalze 35.2 ist dem Auflager 29.1 an dessen der Einschuböffnung 25 zugewandten Ende zugeordnet und überragt geringfügig die am Auflager 29.1 ausgebildete Tischfläche 29.1, wobei die Höhenlage der Förderwalze 35.2 auf nicht näher dargestellte Weise in gewissen Grenzen einstellbar ist.A further facilitation is provided by a further conveyor 35 provided in a further embodiment, by means of which the stack support 26 can be fed to the stack support carrier 29. This further conveyor 35 preferably comprises a conveyor roller 35.2 connected to a drive 35.1, wherein the drive 35.1, as shown by the example according to FIG. 5, is advantageously arranged within the conveyor roller 35.2. In this example, the feed roller 35.2 is an outer ring of an electric motor designed as an outer ring rotor. The feed roller 35.2 is associated with the support 29.1 at its insertion opening 25 facing the end and slightly surmounted the 29.1 formed on the support table surface 29.1, the altitude of the feed roller 35.2 not on closer manner is adjustable within certain limits.

Zur Gewährleistung eines sicheren Transportes der durch Hindurchschieben durch die Einschuböffnung 25 an den weiteren Förderer 35 übergebenen Stapelunterlage 26 umfasst dieser Förderer 35 des weiteren bevorzugt eine Rollenanordnung 35.3, die achsparallel zur Förderwalze 35.2 angeordnet und in Richtung auf diese im vorliegenden Ausführungsbeispiel mittels Schenkelfedern 35.3' vorgespannt ist. In der Position des Auflagers 29.1 auf seinem ersten Niveau ist eine in den Bereich der Förderwalze 35.2 verbrachte Stapelunterlage 26 zwischen der Förderwalze 35.2 und der Rollenanordnung 35.3 aufgrund der genannten Vorspannung der letzteren eingespannt.To ensure safe transport of the transferred by pushing through the insertion opening 25 to the other conveyor 35 stack support 26 of this conveyor 35 further preferably comprises a roller assembly 35.3, the axis parallel to the conveyor roller 35.2 arranged and biased towards them in the present embodiment by means of torsion springs 35.3 ' is. In the position of the support 29.1 at its first level, a stack support 26, which has been brought into the area of the conveying roller 35.2, is clamped between the conveying roller 35.2 and the roller arrangement 35.3 due to the aforementioned pretensioning of the latter.

Zur Absicherung einer im Hinblick auf die Dimensionierung der Stapelunterlagen 26 korrekten Beschickung der Bereitstellungsstation 24 und damit der Stapelstation 14 mit Stapelunterlagen 26 ist des Weiteren ein Anschlag 36 vorgesehen, der die maximale Wandstärke der dem Stapelunterlagenträger 29 zuführbaren Stapelunterlagen 26 auf ein vorbestimmtes Maß beschränkt.To ensure a correct with regard to the dimensioning of the stacking pads 26 feeding the staging station 24 and thus the stacking station 14 with stacking pads 26 further includes a stop 36 is provided, the maximum wall thickness of the Stacking tray carrier 29 feedable stacking pads 26 limited to a predetermined amount.

Im vorliegenden Beispiel ist der Anschlag 36 in Form einer in Fig. 3 im Querschnitt erkennbaren Stange ausgebildet, die sich quer zur Einschubrichtung der Stapelunterlage 26 entlang der Einschuböffnung 25 erstreckt.In the present example, the stop 36 is formed in the form of a recognizable in Fig. 3 in cross-section rod which extends transversely to the insertion direction of the stack support 26 along the insertion opening 25.

Gemäß einer ebenfalls im Hinblick auf eine Beschickung der Bereitstellungsstation 24 mit korrekt dimensionierten Stapelunterlagen 26 getroffenen Vorkehrung ist ein in Fig. 3 angedeuteter Sensor 37 vorgesehen, der nach erfolgtem vollständigen Einschieben der Stapelunterlage 26 in die Bereitstellungsstation 24 ein Signal erzeugt, wenn ein bezüglich der Einschubrichtung nachlaufendes Ende der Stapelunterlage 26 von einer vorbestimmten Position abweicht.According to a provision also made with regard to a loading of the provisioning station 24 with correctly dimensioned stacking supports 26, a sensor 37 indicated in FIG. 3 is provided, which generates a signal after complete insertion of the stacking support 26 into the provisioning station 24, if one with respect to the insertion direction trailing end of the stack support 26 deviates from a predetermined position.

Das nachlaufende Ende einer jeweiligen Stapelunterlage 26 nimmt in deren am Anschlag 34 für die in Einschubrichtung vorauseilende Stirnseite der Stapelunterlage 26 anliegenden Lage, das heißt nach erfolgtem vollständigen Einschieben der Stapelunterlage 26 in die Bereitstellungsstation 24 dann eine vorbestimmte Position ein, wenn es unter Absenken des Auflagers 29.1 in der L-förmigen Ausnehmung des Schenkels 28.1 des Schlittens 28 aufgenommen wird. Andernfalls ist die seitliche Erstreckung der Stapelunterlage 26 zu groß oder zu klein. Mittels des in diesen Fällen vom Sensor 37 erzeugten Signals sind sodann die genannten, im Rahmen 27 integrierten Linearantriebe blockierbar.The trailing end of a respective stack support 26 takes in its stop 34 for the leading edge in the insertion direction of the stack support 26 adjacent layer, that is, after complete insertion of the stack support 26 in the supply station 24 then a predetermined position, if it under lowering the support 29.1 is received in the L-shaped recess of the leg 28.1 of the carriage 28. Otherwise, the lateral extent of the stack support 26 is too large or too small. By means of the signal generated by the sensor 37 in these cases, the said linear drives integrated in the frame 27 can then be blocked.

Unter Berücksichtigung des Umstandes, dass die Bereitstellungsstation 24 von den umlaufenden Greifersystemen 9 durchfahren wird, sind in weiterer Ausgestaltung Sicherheitsvorkehrungen getroffen, die einen manuellen Eingriff in die Einschuböffnung 25 verhindern.Taking into account the fact that the supply station 24 is traversed by the rotating gripper systems 9, in a further embodiment, safety precautions are taken to prevent manual intervention in the insertion opening 25.

Wie in Fig. 3 erkennbar, sehen diese Vorkehrungen bevorzugt vor, dass an der Außenseite der der Einschuböffnung 25 aufweisenden Seitenwand 1.1 ein die Einschuböffnung 25 umgebendes Gehäuse 38 angeordnet ist, welches die Rampe 31, eine der Einschuböffnung 25 vorgeordnete Öffnung 38.1 zum Durchschieben der Stapelunterlage 26 und eine Klappe 38.2 umfasst, welche in einer ersten Stellung derselben die Öffnung 38.1 verschließt, in einer zweiten Stellung die Öffnung 38.1 zum Einschieben der Stapelunterlage 26 freigibt und in der ersten Stellung verriegelbar ist.As can be seen in FIG. 3, these provisions preferably provide that a housing 38 surrounding the insertion opening 25 is arranged on the outside of the side wall 1.1 having the insertion opening 25, which ramp 31, one of the insertion opening 25 upstream opening 38.1 for pushing through the stack support 26 and a flap 38.2, which closes the opening 38.1 in a first position thereof, in a second position, the opening 38.1 for inserting the stack support 26 releases and can be locked in the first position.

Das Gehäuse 38 weist einen Boden in Form der bereits genannten Rampe 31 auf. Diese ist um eine horizontale Achse 38.3 an einem der Seitenwand 1.1 abgewandten Ende des Gehäuses 38 schwenkbar an letzterem aufgehängt und stützt sich mit ihrem der Seitenwand 1.1 zugewandten Ende auf dem Rahmen 27 ab. Die Rampe 31 passt sich somit gegebenenfalls unterschiedlichen Höhenlagen des wie erwähnt heb- und senkbaren Rahmens 27 an.The housing 38 has a bottom in the form of the aforementioned ramp 31. This is about a horizontal axis 38.3 at one of the side wall 1.1 remote from the end of the housing 38 pivotally suspended from the latter and is supported with its side wall 1.1 facing the end of the frame 27 from. The ramp 31 thus adapts optionally to different altitudes of the raised and lowered frame 27 as mentioned.

In Fig. 3 ist die Klappe 38.2 in ihrer die Öffnung 38.1 verschließenden ersten Stellung dargestellt.In Fig. 3, the flap 38.2 is shown in its opening 38.1 occlusive first position.

Die Fig. 6 zeigt die wesentlichen Teile eines Ausführungsbeispieles eines Verriegelungsmechanismusses 39 zur Verriegelung der Klappe 38.2 in deren die Öffnung 38.1 verschließender ersten Stellung. Hiernach umfasst der Verriegelungsmechanismus 39 ein im Querschnitt rechteckig ausgebildetes, im Bereich einer Seitenwand 38.4 des Gehäuses 38 gelegenes Endstück einer mit der Klappe 38.2 fest verbundenen und schwenkbar am Gehäuse 38 angeordneten Klappenachse 39.1, sowie einen schwenkbar an der Seitenwand 38.4 angeordneten Riegel 39.2 in Form eines zweiarmigen Hebels mit einem zum formschlüssigen Umgreifen des Endstückes der Klappenachse 39.1 ausgebildeten Maul an einem ersten Hebelende und einem am zweiten Hebelende angreifenden, an der Seitenwand 38.4 angelenkten, beispielsweise pneumatisch beaufschlagbaren Stellzylinder 39.3, mittels welchem das Maul des Riegels 39.2 in bzw. außer Eingriff mit dem genannten Endstück der Klappenachse 39.1 bringbar ist. Im Eingriff ist eine Schwenkbewegung der Klappe 38.2 aufgrund der Geometrie des Endstückes der Klappenachse 39.1 und des Maules des Riegels 39.2 blockiert. Dieser Fall liegt bevorzugt bei einem unbeaufschlagten Zustand des vorzugsweise einfachwirkend ausgebildeten Stellzylinders 39.3 vor.Fig. 6 shows the essential parts of an embodiment of a locking mechanism 39 for locking the flap 38.2 in the opening 38.1 occlusive first position. After that includes the Locking mechanism 39 a rectangular in cross-section, located in the region of a side wall 38.4 of the housing 38 located end piece of the flap 38.2 fixed and pivotally mounted on the housing 38 flap axis 39.1, and a pivotally mounted on the side wall 38.4 arranged latch 39.2 in the form of a two-armed lever a trained for positive engagement of the tail of the damper shaft 39.1 mouth at a first end of the lever and engaging the second end of the lever, articulated on the side wall 38.4, for example pneumatically actuable actuating cylinder 39.3, by means of which the mouth of the bolt 39.2 in or out of engagement with said end piece the flap axis 39.1 can be brought. In engagement is a pivotal movement of the flap 38.2 due to the geometry of the tail of the flap axis 39.1 and the mouth of the bolt 39.2 blocked. This case is preferably present in an unloaded state of the preferably single-acting actuator cylinder 39.3.
