Description

Die Erfindung betrifft ein Stapelelement zur Aufnahme von Solarmodulen für den Transport mit einem Kantenschutz, an den ein Solarmodul anliegen kann, und einer Klemmvorrichtung, die einen quer zur Stapelrichtung verlaufenden Spalt zur Aufnahme des Solarmoduls aufweist. Außerdem betrifft die Erfindung ein Verfahren zum Stapeln von Solarmodulen mit einem Stapelelement. Insbesondere betrifft die Erfindung ein Stapelelement mit Kantenschutz zum Transport von Solarmodulen mit einem Spezialprofil für die Indachmontage.The invention relates to a stacking element for receiving solar modules for transport with an edge protection, to which a solar module can rest, and a clamping device having a transverse to the stacking direction gap for receiving the solar module. Moreover, the invention relates to a method for stacking solar modules with a stacking element. In particular, the invention relates to a stacking element with edge protection for the transport of solar modules with a special profile for in-roof installation.

Ein derartiges Stapelelement ist beispielsweise aus der DE 10 2011 113 143 A1 bekannt. Dieses bekannte Stapelelement wird seitlich auf einen Rand eines Solarmoduls aufgeschoben und es dient dazu, Solarmodule waagerecht liegend zu stapeln. Dieses Stapelelement hat eine einfache Nut zur Aufnahme des Solarmoduls und diese Nut muss individuell an verschiedene Randbereiche eines Solarmoduls angepasst sein. Außerdem greift das Stapelelement das Solarmodul nur an seiner Oberseite und seiner Unterseite und dadurch ist die Klemmkraft begrenzt.Such a stacking element is for example from the DE 10 2011 113 143 A1 known. This known stacking element is pushed laterally onto an edge of a solar module and serves to stack solar modules lying horizontally. This stacking element has a simple groove for receiving the solar module and this groove must be adapted individually to different edge regions of a solar module. In addition, the stacking element engages the solar module only at its top and bottom and thereby the clamping force is limited.

Ein weiteres Stapelelement ist aus der DE 10 2008 012 774 A1 bekannt. Dieses Stapelelement ist für den Eckbereich eines speziellen Solarmoduls ausgebildet. Auch hier wird das Solarmodul nur zwischen zwei an der Oberseite und der Unterseite des Solarmoduls anliegenden Halteflächen gehalten. Ein Arretierungsdorn hat eine hakenartige Form, um ein aufgeschobenes Stapelelement einrasten zu lassen, so dass es am Solarmodul gehalten wird.Another stacking element is from the DE 10 2008 012 774 A1 known. This stacking element is designed for the corner region of a special solar module. Again, the solar module is held only between two voltage applied to the top and bottom of the solar module holding surfaces. A locking mandrel has a hook-like shape for latching a deferred stacking element so that it is held on the solar module.

Die bekannten Stapelelemente greifen das Solarmodul nur an ihrer Oberseite und ihrer Unterseite und dadurch ist nur eine relativ schlechte Verbindung zwischen Stapelelement und Solarmodul zu erreichen. Ein formschlüssig wirkender Arretierungszapfen hat ebenfalls das Problem, dass er keine sichere Verankerung zwischen Solarmodul und Stapelzapfen bewirkt.The known stacking elements grip the solar module only at its top and bottom and thus only a relatively poor connection between stacking element and solar module can be achieved. A form-locking locking pin also has the problem that it does not cause secure anchoring between solar module and stacking pin.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Stapelelement zu entwickeln, das eine sichere Verbindung zwischen Stapelelement und Solarmodul ermöglicht und von verschiedenen Seiten auf ein Solarmodulprofil aufgesteckt werden kann.The invention is therefore based on the object to develop a stacking element that allows a secure connection between stacking element and solar module and can be plugged from different sides to a solar module profile.

Um Solarmodule senkrecht und waagerecht zu transportieren, ist es vorteilhaft, wenn im Eckbereich der Solarmodule Stapelelemente angeordnet werden, die den Eckbereich schützen. In den Eckbereichen liegt das Stapelelement jedoch entweder an der Längsseite oder an der Stirnseite eines Profils an. Derartige Profile haben in der Regel U-förmige Nuten. Daher wurden bisher nur Stapelelemente vorgeschlagen, die eine Haltenut aufweisen, die der Dicke des Randbereichs eines Solarmoduls entspricht. Sofern die Profilierung des Solarmoduls zur Verankerung mit einem Stapelelement genutzt würde, müssten verschiedene Stapelelemente für die Ecken verwendet werden, wodurch die Herstellungskosten steigen und ein erhöhter Aufwand beim Aufbringen der Stapelelemente am Solarmodul entsteht.In order to transport solar modules vertically and horizontally, it is advantageous if in the corner region of the solar modules stacking elements are arranged, which protect the corner area. However, in the corner regions, the stacking element abuts either on the longitudinal side or on the front side of a profile. Such profiles usually have U-shaped grooves. Therefore, only stack elements have hitherto been proposed which have a holding groove which corresponds to the thickness of the edge region of a solar module. If the profiling of the solar module would be used for anchoring with a stacking element, different stacking elements would have to be used for the corners, whereby the manufacturing costs increase and an increased effort arises when applying the stacking elements to the solar module.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Stapelelement bereitzustellen, das an allen vier Ecken auf ein Solarmodul aufgesteckt werden kann und in ein das Solarmodul umgebendes Profil eingreift.The invention is therefore based on the object to provide a stacking element that can be plugged at all four corners on a solar module and engages in a surrounding the solar module profile.

Diese Aufgabe wird mit einem gattungsgemäßen Stapelelement gelöst, bei dem die Klemmvorrichtung einen Klemmzapfen aufweist, der eine Seite des Spaltes bildet.This object is achieved with a generic stacking element in which the clamping device has a clamping pin which forms one side of the gap.

Die Ausbildung eines Klemmzapfens ermöglicht es, diesen Klemmzapfen in eine U-förmige Nut eines Rahmens eines Solarmoduls einzuführen und damit die Profilierung des Solarmoduls dazu zu verwenden, das Stapelelement sicher mit dem Solarmodul zu verbinden.The formation of a clamping pin makes it possible to introduce this clamping pin into a U-shaped groove of a frame of a solar module and thus to use the profiling of the solar module to securely connect the stacking element to the solar module.

Besonders vorteilhaft ist es, wenn die Klemmvorrichtung mehrere und vorzugsweise zwei Klemmzapfen aufweist, die eine Seite des Spaltes bilden. Die Ausbildung mehrerer Klemmzapfen ermöglicht die Herstellung eines Stapelelements, bei dem die Zapfen optimal dazu genutzt werden können, eine sichere Verbindung zwischen Stapelelement und Solarmodul zu ermöglichen.It when the clamping device has a plurality and preferably two clamping pins which form one side of the gap is particularly advantageous. The formation of a plurality of clamping pins allows the production of a stacking element, in which the pins can be optimally used to allow a secure connection between the stacking element and the solar module.

Um nicht nur mit dem Klemmzapfen sondern auch durch die gegenüberliegende Klemmfläche formschlüssig einen Halt zu bewirken, wird vorgeschlagen, dass die dem Klemmzapfen gegenüberliegende Seite des Spaltes eine plane Fläche mit einer sich quer zur Spaltrichtung und quer zur Stapelrichtung erstreckenden Erhebung aufweist. Dies ermöglicht eine erste formschlüssige Verbindung auf einer ersten Seite des Solarmoduls mit den Klemmzapfen und eine zweite formschlüssige Verbindung an der der ersten Seite gegenüber liegenden Seite.In order to positively effect not only with the clamping pin but also by the opposite clamping surface, it is proposed that the clamping pin opposite side of the gap has a flat surface with a transverse to the cleaving direction and transverse to the stacking direction survey. This allows a first positive connection on a first side of the solar module with the clamping pin and a second positive connection on the first side opposite side.

Der Kantenschutz kann eine erste Anlagefläche aufweisen, die sich in Stapelrichtung und quer zur Stapelrichtung erstreckend den Spalt begrenzt. Diese Anlagefläche dient als Anlage des Stapelelements am Solarmodul, wenn das Stapelelement vollständig auf eine Seite des Außenprofils eines Solarmoduls aufgesteckt ist.The edge protector can have a first abutment surface, which delimits the gap in the stacking direction and extending transversely to the stacking direction. This contact surface serves as a contact of the stacking element on the solar module when the stacking element is completely plugged onto one side of the outer profile of a solar module.

Ein Stapelelement kann auch auf eine Ecke eines Solarmoduls aufgesteckt zwei Eckseiten gleichzeitig schützen. Hierzu wird ein Kantenschutz vorgeschlagen, der eine zweite Anlagefläche aufweist, die sich in Stapelrichtung erstreckend den Spalt begrenzt und in einem rechten Winkel zur ersten Anlagefläche verläuft.A stacking element can also be attached to a corner of a solar module to protect two corner pages at the same time. For this purpose, an edge protection is proposed, which has a second contact surface, which extends in the stack direction extending the gap and extends at a right angle to the first contact surface.

Insbesondere wenn das Stapelelement keine zwei senkrecht zueinander stehenden Anlageflächen aufweist, wird vorgeschlagen, dass der Spalt zwei senkrecht zueinander stehende Zugangsöffnungen aufweist, die so ausgebildet sind, dass es an zwei gegenüberliegenden Enden auf ein Profil eines Solarmoduls schiebbar ist.In particular, when the stacking element has no two mutually perpendicular abutment surfaces, it is proposed that the gap has two mutually perpendicular access openings which are formed so that it can be pushed at two opposite ends to a profile of a solar module.

Um mehrere Stapelelemente ineinander zu stecken, wird vorgeschlagen, dass das Stapelelement an einer Oberseite sich in Stapelrichtung erstreckende Stapelzapfen und an einer Unterseite entsprechende Stapelzapfenaufnahmen aufweist.In order to insert a plurality of stacking elements into one another, it is proposed that the stacking element has stacking pins extending on an upper side in the stacking direction and stacking pin receivers corresponding to a lower side.

Sowie ein Solarmodulpaket mit Stapelelementen aufeinander gestapelt ist, wird dieses Paket mit um das Paket verlaufenden Bändern gesichert. Hierbei ist es vorteilhaft, die Bänder im Bereich der Stapelelemente um das Paket zu führen. Da die Stapelelemente jedoch vorzugsweise im Eckbereich eines derartigen Solarmodulpakets angeordnet sind, muss sichergestellt werden, dass die Bänder nicht vom Stapelelement abrutschen. Daher wird vorgeschlagen, dass das Stapelelement in Stapelrichtung verlaufende Stege aufweist, die von einer in Stapelrichtung liegenden Fläche vorstehen. Diese Stege sind derart beabstandet, dass an der in Stapelrichtung verlaufenden Seitenfläche eines Stapelelements zwischen diesen Stegen Bänder sicher geführt werden können.As soon as a solar module package with stacking elements is stacked on top of each other, this package is secured with tapes running around the package. It is advantageous here to guide the bands in the region of the stack elements around the package. However, since the stacking elements are preferably arranged in the corner region of such a solar module package, it must be ensured that the strips do not slip off the stacking element. It is therefore proposed that the stack element has webs running in the stacking direction, which project from a surface lying in the stacking direction. These webs are spaced such that at the running in the stacking direction side surface of a stacking element between these webs bands can be safely performed.

Kumulativ oder alternativ wird vorgeschlagen, dass das Stapelelement drei in einem Dreieck zueinander angeordnete Stapelzapfen aufweist. Dies ermöglicht einerseits ein sicheres Übereinanderstapeln von Stapelelementen, die ineinander gesteckt werden, und andererseits ermöglicht es zwischen den Stapelzapfen an der Oberseite eines Stapelelements ein Band hindurchzuführen. Die Stapelzapfen haben dadurch neben ihrer Funktion als Stapelelement die weitere Funktion, ein zwischen ihnen liegendes Band sicher zu halten.Cumulatively or alternatively, it is proposed that the stacking element has three stacking pins arranged in a triangle to one another. On the one hand, this allows a secure stacking of stacking elements which are inserted into one another, and on the other hand, it is possible to pass a strip between the stacking pins on the top side of a stacking element. In addition to their function as stacking element, the stacking pegs have the further function of securely holding a band lying between them.

Die der Erfindung zugrunde liegende Aufgabe wird auch mit einem Verfahren zum Stapeln von Solarmodulen mit Stapelelementen gelöst, bei dem vorzugsweise Stapelelemente verwendet werden, die oben beschrieben wurden. Dieses Verfahren zeichnet sich dadurch aus, dass jeweils zwei Stapelelemente an gegenüberliegenden Stirnseiten zweier beabstandeter Profilleisten in entgegengesetzter Richtung eingeschoben werden. Durch das Einschieben der Stapelelemente an den Stirnseiten von Solarmodulprofilen kann die Formgebung des Profils dazu genutzt werden, ein Stapelelement am Solarmodul zu halten. Dabei kann ein Klemmzapfen des Stapelelements in eine Nut eines Solarmodulprofils eingeschoben werden, so dass der Zapfen entweder längs der Nut oder quer zur Nut angeordnet ist.The object underlying the invention is also achieved with a method for stacking solar modules with stacking elements, in which stacking elements are preferably used, which were described above. This method is characterized in that in each case two stack elements are inserted at opposite end faces of two spaced profile strips in the opposite direction. By inserting the stacking elements on the end faces of solar module profiles, the shape of the profile can be used to hold a stacking element on the solar module. In this case, a clamping pin of the stacking element in a groove of a Solar module profile can be inserted so that the pin is arranged either along the groove or transverse to the groove.

Besonders vorteilhaft ist bei einem derartigen Verfahren, wenn beim Aufschieben des Stapelelements auf das Solarmodul zwei gegenüberliegende Flächen gespreizt werden, so dass ein Anpressdruck entsteht, der das Herausfallen des Stapelelements verhindert. Dabei ist eine der gegenüberliegenden Flächen vorzugsweise ein Klemmzapfen des Stapelelements.In such a method, it is particularly advantageous if, when the stacking element is pushed onto the solar module, two opposing surfaces are spread so that a contact pressure is created which prevents the stacking element from falling out. In this case, one of the opposing surfaces is preferably a clamping journal of the stacking element.

Um ein Paket aus Solarmodulen, die mittels Stapelelementen aufeinander gestapelt sind, zusammen zu halten, ist es besonders vorteilhaft, wenn das Stapelelement Stapelzapfen aufweist, zwischen denen ein Spannband geführt wird.In order to hold together a package of solar modules which are stacked on one another by means of stacking elements, it is particularly advantageous if the stacking element has stacking pins between which a tensioning band is guided.

Die Stapelelemente dienen dazu, ein Solarmodul zu schützen und sie sind so ausgebildet, dass ein Solarmodul oder ein Paket aus mehreren Solarmodulen in senkrechter oder waagerechter Ausrichtung gestapelt und beispielsweise auf handelsüblichen Holzpaletten transportiert werden kann. Die Stapelelemente können unmittelbar nach der Montage des Modulrahmens aufgesteckt werden und verhindern somit Beschädigungen des Modulrahmens in weiteren Prozessschritten. Die Stapelelemente werden erst unmittelbar vor der Endmontage vom Solarmodul entfernt, wodurch die Kanten bis zur endgültigen Montage geschützt werden.The stack elements are used to protect a solar module and they are designed so that a solar module or a package of several solar modules can be stacked in a vertical or horizontal orientation and transported, for example, on standard wooden pallets. The stacking elements can be plugged immediately after mounting the module frame and thus prevent damage to the module frame in further process steps. The stacking elements are removed from the solar module just prior to final assembly, protecting the edges until final assembly.

Here are a first contact surface 2 and a second contact surface 3 as edge protection 4. Between clamping pin 5, 6 and a side opposite this clamping pin side 7, a gap 8 is provided. This gap 8 forms with the side 7 and the opposite clamping pin 5, 6 a clamping device 9, which makes it possible to keep a pushed onto a profile stacking element 1 by means of this clamping device 9 on the profile. The gap 8 is designed so that a profile (not shown) can be clamped in this gap.

Die Seite 7 ist als plane Fläche 10 mit einer Erhebung 11 ausgebildet, so dass die eine Seite 7 des Spaltes 8 von der Fläche 10 und der Erhebung 11 und die andere Seite 12 von den Klemmzapfen 5, 6 gebildet wird. Die Seite 7 des Spaltes 8 erstreckt sich somit quer zur Spaltrichtung 13 und quer zu einer Stapelrichtung 14.The side 7 is formed as a flat surface 10 with a protrusion 11, so that the one side 7 of the gap 8 of the surface 10 and the elevation 11 and the other side 12 is formed by the clamping pin 5, 6. The side 7 of the gap 8 thus extends transversely to the splitting direction 13 and transversely to a stacking direction 14.

Diese Stapelrichtung 14 ergibt sich daraus, dass mehrere Stapelelemente 1 aufeinander gestapelt werden können. Hierzu sind an der Oberseite des Stapelelementes 1 sich in Stapelrichtung 14 erstreckende Stapelzapfen 16, 17, 18 und an einer Unterseite 19 entsprechende Stapelzapfenaufnahmen 20, 21, 22 vorgesehen. Mehrere Stapelelemente können somit übereinander gestapelt werden, indem jeweils die Stapelzapfen 16, 17, 18 in die Stapelzapfenaufnahmen 20, 21, 22 eines zweiten Stapelelementes geschoben werden. Dadurch entsteht eine Stange aus mehreren Stapelelementen 1, die jeweils einen Spalt 8 mit zwei senkrecht zueinander stehenden Zugangsöffnungen 23, 24 aufweist. Diese Zugangsöffnungen sind so ausgebildet, dass das Stapelelement an zwei gegenüberliegenden Enden auf ein Profil eines Solarmoduls schiebbar ist.This stacking direction 14 results from the fact that several stacking elements 1 can be stacked on top of each other. For this purpose, at the top of the stacking element 1 in the stacking direction 14 extending stacking pins 16, 17, 18 and at a bottom 19 corresponding Stapelzapfenaufnahmen 20, 21, 22 are provided. A plurality of stacking elements can thus be stacked on top of one another by the respective stacking pins 16, 17, 18 being pushed into the stacking pin receivers 20, 21, 22 of a second stacking element. This results in a rod of a plurality of stack elements 1, each having a gap 8 with two mutually perpendicular access openings 23, 24. These access openings are formed so that the stacking element is slidable at two opposite ends on a profile of a solar module.

In Stapelrichtung 14 verlaufende Stege 25 bis 30 dienen der Stabilisierung und insbesondere die Stege 25, 27, 28 und 30 können ein am Stapelelement entlanggeführtes Band gegen ein Verrutschen sichern. Dabei kann das Band an den Stegen 26 und 29 sowie an einem quer verlaufenden Steg 31, der ebenfalls von einer Fläche 32 vorsteht, anliegen.Webs 25 to 30 extending in the stacking direction 14 serve to stabilize, and in particular the webs 25, 27, 28 and 30 can secure a band guided along the stacking element against slipping. In this case, the band on the webs 26 and 29 and on a transverse web 31, which also protrudes from a surface 32, rest.

Das Stapelelement 1 hat in seiner Mitte einen Steg 33 mit zwei Anlageflächen 2 und 34 und es ist zu diesem Steg 33 spiegelbildlich aufgebaut, so dass das Stapelelement 1 zwei Spalte 8 und 35 aufweist, mittels denen das Stapelelement von unterschiedlichen Seiten auf ein Profil eines Solarmoduls klemmend aufschiebbar ist.The stacking element 1 has in its center a web 33 with two contact surfaces 2 and 34 and it is constructed mirror-symmetrically to this web 33, so that the stacking element 1 has two gaps 8 and 35, by means of which the stacking element from different sides to a profile of a solar module slidably pushed.

Während das lange Stapelelement zwei Spalte 8 und 35 aufweist, weist das kompakte Stapelelement 40, das in den Figuren 6 bis 11 dargestellt ist, nur einen Spalt 41 auf. Auch dieser Spalt 41 wird zwischen Klemmzapfen 42, 43 und einer Seite 44 gebildet, die eine plane Fläche 45 und eine sich quer zur Spaltrichtung 46 und quer zu einer Stapelrichtung 47 erstreckenden Erhebung 48 aufweist. Der Kantenschutz 49 weist nur eine Anlagefläche 50 auf, die an der Stirnseite eines Profils anliegt, wenn das kompakte Stapelelement 40 auf die Stirnseite eines Profils aufgesteckt ist.While the long stacking element has two gaps 8 and 35, the compact stacking element 40, which in the FIGS. 6 to 11 is shown, only one gap 41. This gap 41 is also formed between clamping pins 42, 43 and a side 44, which has a flat surface 45 and an elevation 48 extending transversely to the gap direction 46 and transversely to a stacking direction 47. The edge guard 49 has only one contact surface 50, which bears against the end face of a profile, when the compact stacking element 40 is attached to the end face of a profile.

An der Oberseite 51 des kompakten Stapelelementes 40 sind drei in einem Dreieck zueinander angeordnete Stapelzapfen 52, 53 und 54 vorgesehen, für die an der Unterseite 55 entsprechende Stapelzapfenaufnahmen 56, 57 und 58 vorgesehen sind.On the upper side 51 of the compact stacking element 40 three stacking pins 52, 53 and 54 arranged in a triangle are provided, for which corresponding stacking pin receivers 56, 57 and 58 are provided on the underside 55.

Das lange Stapelelement 1 und das kompakte Stapelelement 40 können somit an gegenüberliegenden Seiten zweier beabstandeter Profilleisten in entgegengesetzter Richtung eingeschoben werden. Bei einem Solarmodul, das an zwei gegenüberliegenden Seiten jeweils ein durchlaufendes Profil und dazwischen ein Querprofil aufweist, kann an jedem Ende des durchlaufenden Profils ein Stapelelement aufgesteckt werden. Beide beschriebenen Stapelelemente sind so ausgebildet, dass das gleiche Stapelelement für alle vier Ecken verwendet werden kann. Dabei greifen die Stapelzapfen 5, 6 und 42, 43 in eine Nut des Profils und auch die Erhebungen 11, 48 können in einen entsprechenden nutartigen Bereich des Profils eingreifen.The long stacking element 1 and the compact stacking element 40 can thus be inserted on opposite sides of two spaced profile strips in the opposite direction. In a solar module, which in each case has a continuous profile on two opposite sides and a transverse profile therebetween, a stacking element can be attached at each end of the continuous profile. Both described stacking elements are designed so that the same stacking element can be used for all four corners. In this case, the stacking pins 5, 6 and 42, 43 engage in a groove of the profile and also the elevations 11, 48 can engage in a corresponding groove-like region of the profile.

Die Profilanordnung von Klemmzapfen und Erhebungen kann dabei individuell auf ein spezielles Profil eines Solarmoduls abgestimmt sein. Die Ausbildung der Zapfen ermöglicht es dabei, ein Profil zwischen Zapfen und einer den Zapfen gegenüberliegenden Seite einzuklemmen. Bei dem kompakten Stapelelement 40 kann diese Klemmwirkung sowohl zwischen den Klemmzapfen 42, 43 und einer darunterliegenden Seite 44 als auch zwischen den Klemmzapfen 42, 43 und einer darüber liegenden Seite 49 ausgebildet sein. Je nach Profil sind Position und Form von Zapfen und den Zapfen gegenüberliegenden Seiten individuell auf ein spezielles Profil abstimmbar.The profile arrangement of clamping pin and surveys can be tailored to a specific profile of a solar module. The formation of the pins makes it possible to clamp a profile between the pin and a side opposite the pin side. In the case of the compact stacking element 40, this clamping effect can be formed both between the clamping pins 42, 43 and an underlying side 44 and between the clamping pins 42, 43 and an overlying side 49. Depending on the profile, the position and shape of the pins and the pins opposite the sides can be individually adjusted to a specific profile.

Zur Führung von Bändern ist zwischen den Stapelzapfen 52, 53 und dem Stapelzapfen 54 ein Spalt 60 vorgesehen und an beiden Seiten des Stapelelementes 40 sind Flächen 61, 62 vorgesehen, von denen Stege 63 bis 66 vorstehen.For guiding strips, a gap 60 is provided between the stacking pins 52, 53 and the stacking pin 54, and faces 61, 62 are provided on both sides of the stacking element 40, of which webs 63 to 66 protrude.
