Description

Die vorliegende Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs1 sowie ein Verfahren nach dem Oberbegriff des Anspruchs 7 zum Aufrichten vorwiegend flächiger Materialzuschnitte entlang vorbereiteter Biegekanten.The present invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 7 for erecting mainly flat material blanks along prepared bending edges.

CN 2 330 502 Y zeigt eine Vorrichtung zur Herstellung von Schachteln aus Stanzzuschnitten. Diese umfasst ein Magazin zur Bevorratung der flächigen Stanzzuschnitte mit einer Vereinzelungseinrichtung, eine Einrichtung für den Klebstoffauftrag mit Auftragsdüsen, eine Formeinrichtung zum Aufrichten des beleimten Stanzzuschnittes zu einer Schachtel und Transporteinrichtungen zum Überführen der Zuschnitte zwischen den genannten Bearbeitungseinrichtungen. Die Formeinrichtung umfasst trichterförmige Leitelemente zum Aufrichten der Schachtel, welche aufzurichtende Bereiche des zunächst ebenen Zuschnittes erfassen und entgegen der Transportrichtung des Zuschnittes gegenüber dessen Grundfläche aufstellen. CN 2 330 502 Y shows an apparatus for producing boxes from punched blanks. This comprises a magazine for storing the flat punched blanks with a separating device, a device for the adhesive application with applicator nozzles, a shaping device for erecting the glued punching blank to a box and transport means for transferring the blanks between said processing means. The molding device comprises funnel-shaped guide elements for erecting the box, which detect regions of the initially flat blank to be aligned and set up against the transport direction of the blank opposite its base surface.

Darüber hinaus umfasst die vorgestellte Vorrichtung schwenkbare Elemente zum Umklappen derjenigen Bereiche des Zuschnittes wie bspw. Klebelaschen, welche nicht durch die trichterförmigen Leitelemente erfasst werden.In addition, the presented device comprises pivotable elements for folding over those areas of the blank, such as adhesive tabs, which are not detected by the funnel-shaped guide elements.

Der Aufrichteinrichtung nachgeordnet ist eine Presseinrichtung, welche jeweils eine einzelne aufgerichtete Schachtel aufnimmt, und durch bewegliche Elemente die verklebten Flächen der Schachtel von außen andrückt. Der innere Gegenhalt wird durch den Stempel geleistet, welcher den Zuschnitt durch die Aufrichteinrichtung mit den beschriebenen trichterförmigen Leitelementen in die Presseinrichtung drückt.Downstream of the erecting device is a pressing device, which receives in each case a single erected box, and presses the glued surfaces of the box from the outside by means of movable elements. The inner counterhold is made by the punch, which presses the blank through the erecting device with the described funnel-shaped guide elements in the pressing device.

Bei dem Überführen der Schachtel aus der Aufrichteinrichtung in die zu dieser beabstandeten Presseinrichtung wird die Schachtel nur innenseitig durch den Stempel mittels eines Saugers gehalten, so dass sich die Verklebungen wieder lösen und die Ausrichtung der Klebeflächen zueinander verloren gehen können, was zu Qualitätseinbußen der fertigen Schachteln führt. Darüber hinaus wird die Schachtel mit den aufgerichteten Flächen an ortsfesten Elementen gleitend bewegt, was aufgrund der in den Biegekanten wirkenden Rückstellkräfte zu Markierungen an den Außenflächen der Schachteln führt.When transferring the box from the erecting device into the pressing device spaced therefrom, the box is held only on the inside by the punch by means of a nipple, so that the bonds can be loosened again and the alignment of the adhesive surfaces can be lost to one another, which leads to a loss of quality of the finished boxes leads. In addition, the box with the erected surfaces is slidably moved on stationary elements, resulting in marks on the outer surfaces of the boxes due to the restoring forces acting in the bending edges.

Neben diesen die Qualität beeinträchtigenden Nachteilen ist auch die Produktionsleistung der vorgestellten Vorrichtung stark eingeschränkt, da das Aufrichten eines nachfolgenden Zuschnittes erst erfolgen kann, wenn die Verklebung der vorangehende Schachtel so weit ausgehärtet ist, dass die Klebekräfte die Rückstellkräfte sicher übersteigen und sich die Verklebung der Schachtel bei deren Entnahme aus der Presseinrichtung nicht lösen kann. Erst dann kann der Stempel in seine Ausgangslage zurückkehren und bei einem darauf folgenden Arbeitshub den nächsten Materialzuschnitt erfassen.In addition to these disadvantages affecting the quality, the production performance of the presented device is severely limited, since the erection of a subsequent blank can only take place when the bonding of the preceding box has cured to such an extent that the adhesive forces reliably exceed the restoring forces and the bonding of the box can not solve their removal from the pressing device. Only then can the stamp return to its original position and capture the next material blank in a subsequent working stroke.

Aus CN 103 786 368 A ist eine Vorrichtung zum Formen von einseitig offenen Schachteln aus flächigen Materialzuschnitten durch Aufrichten der Seitenbereiche bekannt, welche eine ortsfeste ringförmige Matrize umfasst und einen beweglichen Stempel, welcher den flächigen Materialzuschnitt in die Matrize drückt. Die formgebende innere Kontur der Matrize setzt sich in einem unmittelbar anschließenden aus vier ortsfesten Wänden gebildeten Schacht fort, welcher bereits aufgerichtete Schachteln aufnimmt. Eine erste sich in der Matrize befindliche Schachtel wird von einer zweiten bei deren Formvorgang in den Schacht voran geschoben. Dieser Vorgang wiederholt sich, so dass sich der Schacht mit ein einem Stapel Schachteln füllt. Der Schacht unterteilt sich in zwei Zonen, wobei eine erste an die Matrize anschließende Zone beheizt und eine zweite Zone gekühlt werden kann.Out CN 103 786 368 A a device is known for forming unilaterally open cartons of sheet material cuts by erecting the side portions comprising a fixed annular die and a movable punch which presses the sheet material blank into the die. The shaping inner contour of the die continues in an immediately adjoining shaft formed of four fixed walls, which accommodates already erected boxes. A first box located in the die is advanced by a second during its molding process into the slot. This process repeats itself so that the shaft fills with a stack of boxes. The shaft is divided into two zones, with a first zone adjacent to the die being heated and a second zone being cooled.

Aufgrund der durch das Formen in den Materialzuschnitt eingebrachten Spannungen tendieren die Schachteln sich zu öffnen, was im Schacht durch dessen Wände verhindert wird. Indem der Schacht gleichzeitig mehrere Schachteln aufnehmen kann, wird bei gleicher Produktionsleistung die je Schachtel für die Stabilisierung deren erwünschten Form verfügbare Zeit entsprechend des Fassungsvermögens des Schachtes vervielfacht. Durch die gezielte Temperaturführung in Durchlaufrichtung wird die Stabilisierung der Form zusätzlich beschleunigt.Due to the stresses introduced by shaping into the material blank, the cartons tend to open, which is prevented in the shaft by its walls. By being able to accommodate a plurality of cartons at the same time, the time available per carton to stabilize its desired shape is multiplied according to the capacity of the shaft, with the same production capacity. Due to the targeted temperature control in the direction of flow, the stabilization of the mold is additionally accelerated.

Innerhalb des Schachtes schieben sich die Schachteln gegenseitig gegen die Reibung an den Schachtwänden weiter. Dies führt dazu dass die Schachteln stellenweise miteinander verkleben und nicht ohne deren Beschädigung voneinander getrennt werden können. Die aufgrund der in den Schachteln wirkenden Spannungen starke Reibung zwischen Schachtel und den Schachtwänden führt insbesondere bei empfindlichen Materialien zu Markierungen und Beschädigungen der Schachteln.Within the shaft, the boxes push each other against the friction on the shaft walls on. This leads to the boxes sticking together in places and can not be separated without their damage. The strong friction between the box and the shaft walls due to the stresses acting in the boxes leads to markings and damage of the boxes, especially in the case of sensitive materials.

Dass eine Schachtel so lange in dem ihre Form stabilisierenden Schacht verbleibt, bis sie von den nachfolgenden Schachteln ausgeschoben wird, führt dazu, dass der Schacht immer mit Schachteln gefüllt ist und bspw. vor Rüstvorgängen erst aufwendig manuell durch das Personal geleert werden muss. Um die Reibung an den Wänden eines solchen festen Schachtes zu reduzieren, schlägt die DE 519 493 C vor, endlos um Rollen umlaufende Bänder in die Schachtwände zu integrieren oder die feststehenden Wände vollständig durch solche Bänder zu ersetzen. Diese Bänder sind jeweils paarweise einander gegenüberliegend angeordnet und begrenzen die Weite des Schachtes. Der Vorschub dieser Bänder wird durch Traktion der mittels eines Stempels in den Schacht eingeschobenen Schachtel erzeugt. Auf diese Weise soll ein Gleiten zwischen den Riemen und der Schachtel vermieden werden. Um Schachteln unterschiedlicher Abmessungen erzeugen zu können, ist der Abstand der Riemen eines Paares zueinander und damit die Weite des Schachtes durch einen Spindeltrieb einstellbar. Abhängig von den zusammenwirkenden Oberflächen der Riemen und der Schachteln kann Schlupf und damit Reibung nicht zuverlässig vermieden werden. Dem entgegenwirkend schlägt die DE 521 084 C vor, die Riemen mit in den Transportschacht ragenden Tragblechen auszurüsten, welche mit den vorlaufenden Kanten der in den Schacht eingeführten Schachteln einen Formschluss bilden. Um Kollisionen mit dem Stempel zu vermeiden, sind die Tragbleche gegen die Riemenoberfläche klappbar gestaltet. Die Anordnung der Tragbleche an den Riemen führt zu einer unveränderlichen Teilung. Bei niedrigen Schachteln ergeben sich damit unnötig große Abstände der Schachteln innerhalb des Schachtes zueinander und damit eine Einschränkung der möglichen Produktionsleistung der Vorrichtung. Aufgabe der Erfindung ist es daher, ein Verfahren der eingangs genannten Art und eine Vorrichtung zu dessen Durchführung zu schaffen, die von den aufgeführten Nachteilen befreit sind.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Vorrichtung nach Anspruch 1 und ein Verfahren nach Anspruch 7, wobei der Vorrichtung zum Aufrichten ausgestreckte Materialzuschnitte mit vorbereiteten Biegekanten und mit Klebstoff versehenen zu fügenden Flächen, einzeln bereitgestellt sind. Jeder Materialzuschnitt wird derart an Aufrichtelementen der Vorrichtung vorbeigeführt, dass sich dessen Seitenwände bildenden Bereiche gegenüber einem Bodenbereich aufrichten und der Materialzuschnitt zu einem einseitig offenen Hohlkörper geschlossen wird. Dazu sieht die Vorrichtung eine erste Transporteinrichtung vor, welche den bereitgestellten Materialzuschnitt erfasst und gegen die durch das aufrichten wirkenden Kräfte an den Aufrichtelementen der Vorrichtung entlang und in einen an diese Aufrichtelemente anschließenden Schacht der Vorrichtung transportiert. In einfacher Weise ist diese erste Transporteinrichtung als ein auf den Bodenbereich des Materialzuschnitts respektive Hohlkörpers wirkender Stempel gestaltet.
Der innere Querschnitt des Schachtes entspricht den Außenabmessungen der Hohlkörper, so dass Elemente des Schachtes die durch das Aufrichten geschlossenen Kanten des Hohlkörpers geschlossen halten. Dadurch wird der Hohlkörper in seiner Form gehalten, so lange er sich in dem Schacht befindet. Dieser ist so lang gestaltet, dass er mehrere hintereinander angeordnete Hohlkörper gleicher Bodenfläche aufnehmen kann, so dass sich die Verweildauer jedes Hohlkörpers in dem Schacht entsprechend verlängert. Dadurch verlängert sich auch die Zeitspanne, in der die verklebten Flächen derart stabilisiert werden, dass ein Verschieben der Klebeflächen zueinander oder gar ein Öffnen der Verklebungen sicher vermieden werden. Diese Aushärtezeit, in der die Verklebungen vor Belastung geschützt sind ergibt sich aus der Produktionsleistung der Vorrichtung und der Länge des Schachtes. Erfindungsgemäß umfasst der Schacht wenigstens eine weitere Transporteinrichtung, welche den Vorschub der aufgenommenen Hohlkörper innerhalb des Schachtes in dessen Längsrichtung sicherstellt, wobei die Hohlkörper stets zueinander beabstandet sind. Damit wird ein unbeabsichtigtes Verkleben der Hohlkörper miteinander auch bei ggf. herausquellenden Klebstoffresten verhindert und ein Leeren des Schachtes auf einfache Weise ermöglicht. Wenigstens ein Transportelement der Transporteinrichtung erfasst dabei eine der durch das Aufrichten verklebten Kanten oder dieser benachbarte Flächen derart in einer Nut des Transportelementes, dass das Transportelement den Hohlkörper förderwirksam erfasst und selbst die Kante geschlossen hält. Auf diese Weise kann die Konstruktion des Schachtes mit dessen wenigstens einer Transporteinrichtung sehr kompakt und einfach gehalten werden, und Relativbewegungen zwischen der verklebten Kante und dem diese geschlossen haltenden Element während des Vorschubes des Hohlkörpers und damit Beschädigungen des Hohlkörpers werden vermieden. In vorteilhafter Gestaltung der Vorrichtung ist jeder durch das Aufrichten verklebten Kante des Hohlkörpers eine Transporteinrichtung mit jeweils diese zugeordnete Kante geschlossen haltendem Transportelement vorgesehen, wodurch alle verklebten Kanten in gleicher Weise zum Aushärten fixiert werden. Darüber hinaus wirken somit sämtliche Haltekräfte der Transporteinrichtungen unmittelbar stabilisierend auf alle Klebestellen. Auf ortsfeste Leitelemente, an denen die Hohlkörper unter Reibung und der Gefahr von Beschädigungen gleiten kann auf diese Weise insbesondere bei kleinen Abmessungen der Hohlkörper verzichtet werden.
The fact that a box remains in the shaft stabilizing its shape until it is pushed out of the subsequent boxes leads to the fact that the shaft always filled with boxes and, for example, must first be manually emptied manually by the staff before set-up operations. To reduce the friction on the walls of such a fixed shaft, the DE 519 493 C to integrate continuously circulating belts into the shaft walls or to completely replace the fixed walls with such belts. These bands are arranged in pairs opposite each other and limit the width of the shaft. The feed of these bands is produced by traction of the inserted by means of a punch into the box. In this way, a sliding between the belt and the box should be avoided. In order to produce boxes of different dimensions, the distance between the belt of a pair to each other and thus the width of the shaft is adjustable by a spindle drive. Depending on the cooperating surfaces of the belts and boxes slip and thus friction can not be reliably avoided. The counteracting beats the DE 521 084 C prior to equip the belt with projecting into the transport shaft support plates, which form a positive connection with the leading edges of the inserted into the shaft boxes. To avoid collisions with the stamp, the support plates are designed hinged against the belt surface. The arrangement of the support plates on the belt leads to a constant pitch. With low boxes, this results in unnecessarily large distances of the boxes within the shaft to each other and thus a restriction of the possible production capacity of the device. The object of the invention is therefore to provide a method of the type mentioned and an apparatus for its implementation, which are exempt from the disadvantages listed.
According to the invention, this object is achieved by a device according to claim 1 and a method according to claim 7, wherein the device for erecting stretched material blanks with prepared bending edges and provided with adhesive surfaces to be joined, are provided individually. Each material blank is guided past erecting elements of the device in such a way that its side walls forming regions upright with respect to a bottom area and the material blank is closed to a hollow body open on one side. For this purpose, the device provides a first transport device, which detects the material blank provided and transports it against the forces acting on the erecting elements of the device through the straightening up and into a shaft of the device adjoining these erecting elements. In a simple way, this first transport device is designed as acting on the bottom portion of the material blank respectively hollow body stamp.
The inner cross section of the shaft corresponds to the outer dimensions of the hollow body, so that elements of the shaft hold the closed by the erecting edges of the hollow body. As a result, the hollow body is held in its shape as long as it is in the shaft. This is designed so long that it can accommodate a plurality of successively arranged hollow body same floor surface, so that the residence time of each hollow body in the shaft corresponding extended. As a result, the time span in which the glued surfaces are stabilized in such a way that displacement of the glued surfaces relative to one another or even opening of the glued joints is reliably prevented. This curing time, in which the bonds are protected from stress results from the production of the device and the length of the shaft. According to the invention, the shaft comprises at least one further transport device, which ensures the advance of the hollow bodies received within the shaft in its longitudinal direction, wherein the hollow bodies are always spaced from each other. This prevents unintentional sticking of the hollow bodies to one another even if glue residues are able to swell out, and makes it possible to empty the shaft in a simple manner. In this case, at least one transport element of the transport device detects one of the edges glued by the erecting or of these adjacent surfaces in such a way in a groove of the transport element that the transport element detects the hollow body in an effective manner and even keeps the edge closed. In this way, the construction of the shaft with its at least one transport device can be kept very compact and simple, and relative movements between the bonded edge and the element holding this closed during the advancement of the hollow body and thus damage to the hollow body are avoided. In an advantageous embodiment of the device each adhering by erecting the edge of the hollow body, a transport device is provided with this associated edge closed holding transport element, whereby all bonded edges are fixed in the same way for curing. In addition, thus all holding forces of the transport devices act directly stabilizing on all splices. On stationary guide elements, where the hollow body slide under friction and the risk of damage can be dispensed with in this way, especially in small dimensions of the hollow body.

Vorzugsweise umfasst jedes der den Hohlkörper im Bereich einer Kante erfassendes Transportelement eine diese Kante aufnehmende Nut, so dass ein Formschluss zwischen dem Transportelement und der aufgenommenen Kante erzeugt wird und es auf besonders einfache Weise möglich ist die Kante geschlossen zu halten.Preferably, each of the hollow body in the region of an edge detected transport element comprises a groove receiving this edge, so that a positive connection between the transport element and the recorded edge is generated and it is possible in a particularly simple manner to keep the edge closed.

In bevorzugter Gestaltung der Vorrichtung, ist das Transportelement derart gestaltet, dass es neben der Transportfunktion auch das Aufrichten des jeweils erfassten Seitenbereiches bewirkt, so dass auf separate Aufrichtelemente verzichtet werden kann, was eine einfache und übersichtliche Konstruktion einer kombinierten Aufricht- und Halteeinrichtung ermöglicht.In a preferred embodiment of the device, the transport element is designed such that it causes not only the transport function and the erection of each detected side area, so that can be dispensed with separate righting, which allows a simple and clear construction of a combined erecting and holding device.

Um den Aufbau der in dem Schacht wirkenden Transporteinrichtung einfach zu halten und auf einfache Weise einstellbare Abstände der Hohlkörper zueinander im Schacht zu ermöglichen, umfasst die Transporteinrichtung ein umlaufendes Transportelement, wie bspw. einen Riemen. In diesem Fall bildet der den Schachteinlauf bildende Umlenkradius des umlaufenden Transportelementes das Aufrichtelement.In order to keep the structure of the transport device acting in the shaft simple and to allow easily adjustable distances of the hollow body to each other in the shaft, the transport device comprises a revolving transport element, such as. A belt. In this case, the deflecting radius of the circulating transport element forming the shaft inlet forms the erecting element.

Ein produktschonender Transport sowie variable Abstände der Hohlkörper zueinander durch veränderbare Bewegungsprofile wird durch einen mit der Steuerung der Vorrichtung verbundener steuerbarer Antrieb der wenigstens einen zweiten Transporteinrichtung erreicht.A product-friendly transport and variable distances of the hollow body to each other by variable motion profiles is by a with the control of the device connected controllable drive reaches the at least one second transport device.

Figur 1 zeigt einen für das Aufrichten vorbereiteten Materialzuschnitt 1, welcher der Aufrichteinrichtung bereitgestellt ist. Dessen den Boden 6 und die Seitenwände 3 des zu erzeugenden Hohlkörpers 2 bildenden Bereiche kommen dabei in derselben Ebene oberhalb der Aufrichtelemente 7 zu liegen. Die zu verklebenden Flächen 5 sind bereits mit Klebstoff versehen und der Zuschnitt ist zu den Aufrichtelementen 7 ausgerichtet. FIG. 1 shows a ready for erecting material blank 1, which is provided to the erector. Wherein the bottom 6 and the side walls 3 of the hollow body 2 to be formed forming regions come to lie in the same plane above the erecting elements 7. The surfaces 5 to be bonded are already provided with adhesive and the blank is aligned with the erecting elements 7.

Die Vorrichtung umfasst neben den Aufrichtelementen 7 Transporteinrichtungen 9, welche jeweils eine durch das Aufrichten des Hohlkörpers 2 erzeugte Kante 4 erfassen und einen sich in Transportrichtung S der Hohlkörper erstreckenden Schacht 8 bilden, welcher mehrere aufgerichtete Hohlkörper 2 aufnehmen kann. Der Schacht 8 ist entsprechend der Transportrichtung S gegenüber der Vertikalen geneigt, wodurch bei geringem Platzbedarf und guter Zugänglichkeit eine große Länge des Schachtes 8 und damit eine große Aufnahmekapazität erreicht werden können und eine einfache Zufuhr der Materialzuschnitte 1 möglich wird.In addition to the erecting elements 7, the device comprises transport devices 9, which each detect an edge 4 created by erecting the hollow body 2 and form a shaft 8 extending in the transport direction S of the hollow body, which can receive a plurality of raised hollow bodies 2. The shaft 8 is inclined according to the transport direction S relative to the vertical, whereby a small length and good accessibility, a large length of the shaft 8 and thus a large absorption capacity can be achieved and a simple supply of the material blanks 1 is possible.

Der wie in Figur 1 gezeigte bereitgestellte Zuschnitt wir durch einen nicht dargestellten, in einer Ausgangsstellung startenden und in Transportrichtung S wirkenden Stempel entlang der Aufrichtelemente 7 so weit in den Schacht eingeführt, dass sich die Seitenflächen 3 aufrichten und der so erzeugte Hohlkörper 2 sicher von den Transporteinrichtungen 9 des Schachtes 8 erfasst wird. Anschließend kehrt der Stempel in umgekehrter Richtung in seine Ausgangsstellung zurück.The like in FIG. 1 The blank provided, we are introduced by a not shown, starting in a starting position and acting in the direction of transport S stamp along the righting elements 7 in the shaft so that the side surfaces 3 upright and the hollow body 2 thus produced safely from the transport means 9 of the shaft eighth is detected. Subsequently, the stamp returns in the reverse direction to its original position.

Die Aufrichtelemente 7 werden durch Rollen gebildet, welche in einfacher Weise frei drehbar gelagert und mit einer elastischen Oberfläche ausgestattet sind, so dass Beschädigungen des Zuschnittes 1 bzw. des Hohlkörpers 2 vermieden werden. Diese Rollen sind jeweils paarweise angeordnet, wobei jeder durch das Aufrichten in Transportrichtung S zu erzeugenden Kanten 4 ein Paar Rollen 7 zugeordnet ist, so dass auf jede der Seitenwände 3 jeweils zwei unterschiedlichen Paaren zugehörige Rollen 7 wirken. Die Rollen 7 sind wie in Figur 4 gezeigt derart ausgerichtet, dass ihre Drehachse jeweils parallel zu der durch sie aufgerichteten Seitenwand 3 und senkrecht zur Transportrichtung S orientiert ist.The erecting elements 7 are formed by rollers which are freely rotatably mounted in a simple manner and are provided with an elastic surface, so that damage to the blank 1 or the hollow body 2 is avoided. These rollers are each arranged in pairs, each associated with the erecting in the direction of transport S edges 4 a pair of rollers 7, so act on each of the side walls 3 each two different pairs of associated rollers 7. The rollers 7 are as in FIG. 4 shown oriented such that its axis of rotation is oriented in each case parallel to the erected by them side wall 3 and perpendicular to the transport direction S.

Jede der Transporteinrichtungen 9 umfasst einen sich im wesentlichen in Transportrichtung S erstreckenden Träger 14, an dessen dem Schachtausgang zuweisenden Ende eine Riemenscheibe 11 und an dessen dem Schachteingang zuweisenden Ende eine Umlenkrolle 12 angeordnet sind. Als Transportelement umschlingt ein Riemen 10 die Riemenscheibe 11 und die Umlenkrolle 12. Zum Einstellen der Riemenspannung ist eine ebenfalls an dem Träger 14 befestigte Spannrolle 17 vorgesehen. Der die Hohlkörper 2 erfassende Trum des Riemens 10 ist durch eine Schiene 13 unterstützt, so dass der Riemen 10 sowohl in Transportrichtung geführt wird als auch ohne übermäßige Spannung des Riemens 10 eine die Hohlkörper 2 haltende Normalkraft auf die Hohlkörper übertragen kann. Diese Schiene13 ist gegenüber dem Träger 14 derart gefedert befestigt, dass auch bei geringfügig fehlerhafter Positionierung der Transporteinrichtung 9 oder bei abweichenden Abmessungen der Hohlkörper diese einerseits sicher gehalten, andererseits aber auch nicht beschädigt werden. Abhängig von dem zu verklebenden Material und eingesetzten Klebstoff kann ein derart gezielt aufgebrachter Druck auf die Klebeflächen das Abbinden beschleunigen.Each of the transport devices 9 comprises a carrier 14 which extends substantially in the transport direction S and at the end of which the shaft exit has a belt pulley 11 and at the end of which the shaft entrance points a deflection roller 12. As a transport element, a belt 10 wraps around the pulley 11 and the guide pulley 12. To adjust the belt tension, a tensioning roller 17, likewise fastened to the carrier 14, is provided. Of the hollow body 2 detected strand of the belt 10 is supported by a rail 13, so that the belt 10 is guided both in the transport direction and without excessive tension of the belt 10, a hollow body 2 holding normal force can be transmitted to the hollow body. This rail 13 is fixed in such a manner sprung with respect to the carrier 14 that even if the transport device 9 is positioned slightly incorrectly or if the dimensions of the hollow bodies differ slightly, they are securely held, but not damaged. Depending on the material to be bonded and the adhesive used, such a deliberately applied pressure on the adhesive surfaces can accelerate setting.

Die Transporteinrichtungen 9 sind jeweils in der durch die Böden 6 der Hohlkörper 2 aufgespannten Flächen verschiebbar, so dass sie auf unterschiedliche Formate der Zuschnitte 1 respektive Hohlkörper 2 eingestellt werden können. Dabei sind die Riemen 10 jeweils symmetrisch zu der ihnen zugeordneten Kante 4 der Hohlkörper 2 ausgerichtet, wie in Figur 4 dargestellt. Um zusätzlich zu der Transportfunktion die frisch verklebte Kante 4 gegen die in den Biegekanten wirkenden Rückstellkräfte geschlossen zu halten, weisen die Riemen 10 auf ihrer Tragseite eine Nut mit dem Querschnitt eines gleichseitigen Dreiecks auf, wobei der Öffnungswinkel, wie in Figur 4 dargestellt, der Kontur der zu haltenden Kante 4 entspricht. Um trotz des dadurch recht dicken Querschnittes des Riemens 10 kleine Umlenkradien zu ermöglichen, weisen diese eine Sommerung auf.The transport devices 9 are displaceable in each case in the surfaces spanned by the bottoms 6 of the hollow body 2, so that they can be adjusted to different formats of the blanks 1, respectively hollow body 2. The belts 10 are each aligned symmetrically with respect to their associated edge 4 of the hollow body 2, as in FIG. 4 shown. In order to keep the freshly glued edge 4 closed against the restoring forces acting in the bending edges in addition to the transport function, the belts 10 have on their support side a groove with the cross section of an equilateral triangle, wherein the opening angle, as in FIG. 4 represented, the contour of the edge 4 to be held corresponds. In order to allow 10 small deflection radii despite the thus fairly thick cross-section of the belt, they have a summering on.

Figur 3 zeigt, wie vier solcher Transporteinrichtungen 9 einen mehrere quaderförmige Hohlkörper 2 aufnehmenden Schacht 8 bilden. Mit einer geänderten Anordnung und ggf. Anzahl an Transporteinrichtungen 9 können auch Hohlkörper anderer Geometrien erzeugt werden. Der dargestellte Abstand a der Hohlkörper 2 zueinander wird durch das Zusammenspiel der Bewegungsprofile des nicht dargestellten Stempels einerseits und der Riemen 10 der Transporteinrichtungen 9 andererseits erzeugt. Um diese Abstände unabhängig von der Höhe der Hohlkörper 2 zu erzeugen, ist für die Transporteinrichtungen 9 ein nicht dargestellter steuerbarer Antrieb 19 vorgesehen, welcher mit der Steuerung C der Vorrichtung verbunden ist. FIG. 3 shows how four such transport devices 9 form a multiple cuboid hollow body 2 receiving shaft 8. With a modified arrangement and possibly number of transport devices 9 and hollow body of other geometries can be produced. The illustrated distance a of the hollow body 2 to each other is generated by the interaction of the movement profiles of the punch, not shown, on the one hand and the belt 10 of the transport devices 9 on the other hand. In order to generate these distances regardless of the height of the hollow body 2, a not shown controllable drive 19 is provided for the transport means 9, which is connected to the control C of the device.

Um ein Wölben der Seitenwände 3 nach außen bei großen Formaten zu unterdrücken, sind zusätzliche Führungen 15 vorgesehen, die mittig zwischen jeweils zwei Transporteinrichtungen 9 angeordnet sind.In order to suppress buckling of the side walls 3 to the outside in large formats, additional guides 15 are provided, which are arranged centrally between each two transport means 9.

In einer alternativen Ausführung wird auf die Aufrichtelemente 7 verzichtet und deren Funktion wird jeweils von dem um die Umlenkrollen 12 geschlungenen Einlaufbereich der Riemen 10 erfüllt.In an alternative embodiment, the erecting elements 7 are dispensed with and their function is fulfilled in each case by the inlet region of the belts 10 looped around the deflecting rollers 12.
