Description

Die Erfindung betrifft ein Verfahren zum Einbringen eines die Feder einer mit einer Feder-/Nut-Profilierung versehenen Platte, insbesondere eines Bodenpaneels, bildenden Verriegelungselementes, in eine an einer der Seitenkanten der Platte vorhandene ersten Nut, wobei der Streifen Verriegelungsmittel aufweist, durch die zwei über die Feder/Nut verbundenen Platten zueinander quer in Verbindungsrichtung verriegelbar sind.The invention relates to a method for introducing a spring of a provided with a tongue / groove profiling plate, in particular a bottom panel, forming the locking element, in a present on one of the side edges of the plate first groove, wherein the strip has locking means, through the two via the spring / groove connected plates can be locked to each other transversely in the connecting direction.

Aus der DE 100 34 409 A1 sind Bauplatten, insbesondere Bodenpaneele mit einem Kern aus Holzwerkstoff bekannt, die an mindestens zwei sich gegenüberliegenden Seitenkanten mit über ihre volle Längs- und/oder Querseite verlaufenden Nuten versehen sind. Die erste Nut und die gegenüberliegende zweite Nut des Paneels sind spiegelsymmetrisch ausgebildet. Das Verbindungselement ist mit Widerhaken versehen. Werksseitig wird das Verbindungselement in eine der Nuten eingesetzt. Es bildet dann die Feder des Paneels aus. Zur Verbindung zweier Paneele wird die Feder des einen Paneels in die Nut des anderen Paneels eingeschoben. Durch die Widerhaken an dem Verriegelungselement werden die beiden Platten dann zueinander quer in Verbindungsrichtung verriegelt. Grundsätzlich sind solche Platten als Click-Paneele bekannt. Damit können Bodenpaneele leimlos schwimmend miteinander verlegt werden. An sich ist es bekannt, die Feder des Paneels aus dem Kernmaterial herauszufräsen.From the DE 100 34 409 A1 Building panels, in particular floor panels with a core of wood-based material are known, which are provided on at least two opposite side edges over their full longitudinal and / or transverse side extending grooves. The first groove and the opposite second groove of the panel are mirror-symmetrical. The connecting element is barbed. By default, the connecting element is inserted into one of the grooves. It then forms the spring of the panel. To connect two panels, the spring of one panel is inserted into the groove of the other panel. By the barbs on the locking element, the two plates are then locked to each other transversely in the connecting direction. Basically, such plates known as click panels. So floor panels can be installed floating without glue. As such, it is known to mill the spring of the panel out of the core material.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem das Verriegelungselement maschinell in die erste Nut der Platte eingesetzt werden kann.The invention has for its object to provide a method by which the locking element can be used by machine in the first groove of the plate.

Die Lösung der Aufgabe erfolgt mit den eingangs erläuterten Bauteilen durch folgende Schritte:

  1. a) die Platte und das Verriegelungselement werden mit derselben Geschwindigkeit zueinander parallel entlang einer Transportstrecke in eine Transportrichtung T transportiert.
  2. b) das Verriegelungselement läuft während des Transportes seitlich an einer die Transportstrecke in Transportrichtung T stetig verengenden ortsfesten Einrichtung an,
  3. c) mittels der Einrichtung wird das Verriegelungselement stetig zunehmend quer zur Transportrichtung T verlagert, bis es dabei
  4. d) mit seinem in Bezug auf die Transportrichtung T vorderen Ende beginnend stetig zunehmend in die Nut der Platte eingedrückt wird.
The object is achieved with the components explained in the introduction by the following steps:
  1. a) the plate and the locking element are transported at the same speed to each other in parallel along a transport path in a transport direction T.
  2. b) the locking element runs during transport laterally on a transport path in the transport direction T steadily narrowing stationary device,
  3. c) by means of the device, the locking element is steadily increasingly displaced transversely to the transport direction T until it thereby
  4. d) is pressed with its beginning in relation to the transport direction T front end steadily increasing in the groove of the plate.

Durch die erfindungsgemäßen Schritte ist es möglich, entlang einer Fertigungsstraße mit hoher Taktfrequenz die Verriegelungselemente einzusetzen. Dadurch, dass die Platte und das Verriegelungselement mit derselben Geschwindigkeit transportiert werden, ist keine Relativverschiebung der beiden Bauteile zueinander möglich, so dass das Verriegelungselement sicher und reproduzierbar in die vorgegebene Position in der Nut in der Platte eingedrückt wird.The steps according to the invention make it possible to use the locking elements along a production line with a high clock frequency. Characterized in that the plate and the locking element are transported at the same speed, no relative displacement of the two components to each other is possible, so that the locking element is pressed reliably and reproducibly in the predetermined position in the groove in the plate.

Vorzugsweise wird die Platte durch mindestens ein umlaufend angetriebenes Band transportiert, auf dem in Transportrichtung T zueinander beabstandete Mitnehmer angeordnet sind und jeweils ein Mitnehmer sowohl die Platte als auch das Verriegelungselement ergreift.Preferably, the plate is transported by at least one circumferentially driven belt, are arranged on the spaced apart in the transport direction T driver and a respective driver engages both the plate and the locking element.

Durch diese Ausgestaltung ist es möglich, die Platten in einem Magazin zu lagern, einzeln auf das Band zu übergeben, wo der Mitnehmer dann an die Rückseite der Platte anläuft und diese vortransportiert.By this configuration, it is possible to store the plates in a magazine, to pass individually to the tape, where the driver then starts against the back of the plate and transported this forward.

Vorzugsweise sind auf dem Band quer zur Transportrichtung eine Mehrzahl von Mitnehmern angeordnet, so dass insbesondere dann, wenn das Verriegelungselement in die Querseite der Platte eingebracht wird, eine sichere Führung der Platte an ihrer Längsseite geführt ist.Preferably, a plurality of carriers are arranged on the belt transversely to the transport direction, so that in particular when the locking element is introduced into the transverse side of the plate, a secure guidance of the plate is guided on its longitudinal side.

Die Platte kann auch durch mehrere umlaufend angetriebene, zueinander parallel angeordnete Bänder transportiert werden, wobei dann auf jedem Band in Transportrichtung T zueinander beabstandete Mitnehmer angeordnet sind und jeweils ein Mitnehmer auf nur einem Band sowohl die Platte als auch den Streifen transportiert. In diesem Fall muss nur sichergestellt sein, dass die einzelnen Bänder synchron angetrieben und die Mitnehmer der einzelnen Bänder auch quer zur Transportrichtung zueinander parallel umlaufen, um zu verhindern, dass die Platte während des Transportes schräg gestellt wird.The plate can also be transported by a plurality of circumferentially driven, mutually parallel bands, in which case on each band in the transport direction T spaced apart drivers are arranged and each carries a carrier on only one band both the plate and the strip. In this case, it must only be ensured that the individual belts are driven synchronously and the carriers of the individual belts also run parallel to one another transversely to the transport direction in order to prevent the plate from being tilted during transport.

Vorzugsweise ergreift der Mitnehmer zunächst die Platte und dann das Verriegelungselement.Preferably, the driver first grips the plate and then the locking element.

Die Einrichtung, über die das Verriegelungselement in die Nut eingedrückt wird, besteht vorzugsweise aus einer sich in Transportrichtung T erstreckenden Schiene mit einer sich in Richtung der Seitenkante der Platte öffnenden Nut, wobei der Nutgrund der Nut in Richtung der Nutöffnung schräg verläuft. Durch diese Ausgestaltung wird das Verriegelungselement in Transportrichtung T schräg gestellt und an seinem vorderen Ende beginnend in die Nut der Platte stetig eingedrückt.The device by means of which the locking element is pressed into the groove preferably consists of a rail extending in the transporting direction T with a groove opening in the direction of the side edge of the plate, the groove base of the groove running obliquely in the direction of the slot opening. By this configuration, the locking element is inclined in the transport direction T and pressed continuously at its front end starting in the groove of the plate.

Das Verriegelungselement wird vorzugsweise von einem an dem Mitnehmer ausgebildeten Vorsprung ergriffen, der in die Nut der Schiene eintaucht. Die Nut entspricht in ihrer Breite der Dicke des Verriegelungselementes, so dass sich eine Zwangsführung des Verriegelungselementes einstellt.The locking element is preferably gripped by a projection formed on the driver which dips into the groove of the rail. The groove corresponds in width to the thickness of the locking element, so that adjusts a forced operation of the locking element.

Insbesondere wenn der Streifen aus Kunststoff besteht und von einer Rolle zugefördert und abgelängt wird, verhindert die Zwangsführung durch die Nut, dass das Verriegelungselement sich verwellt oder gekrümmt transportiert wird.In particular, when the strip is made of plastic and is conveyed by a roller and cut to length, the positive guidance through the groove prevents the locking element is verwelten or curved transported.

Die Transporteinrichtung besteht aus den drei parallel zueinander angeordneten um Umlenkrollen 7, 8 umlaufend angetriebenen Bändern 1, 1a, 1b. In Transportrichtung T sind auf den Bändern 1, 1a, 1b Mitnehmer 2, 2a, 2b regelmäßig beabstandet angeordnet. Die Mitnehmer 2, 2a, 2b stehen über die Förderbänder 1, 1a, 1b in vertikaler Richtung hervor und sind in Querrichtung Q zueinander parallel ausgerichtet. Die Mitnehmer 2, 2a, 2b greifen an der hinteren Längskante einer Platte 6 an und nehmen die Platte 6 so in Transportrichtung T mit. Seitlich zu dem Förderband 1 ist in der Transportstrecke eine aus einer Schiene 3 bestehende Einrichtung angeordnet, die eine sich in Richtung des Bandes 1 öffnende Nut 9 aufweist. Wenn die Platte 6 an der Schiene 3 vorbeigeführt wird, liegen sich die in der Seitenkante der Platte 6 eingefräste erste Nut 5 und die Nut 9 der Schiene 3 gegenüber. In die Nut 9 ist das streifenförmige Verriegelungselement 4 eingelegt. Der Nutgrund 9a der Nut 3 verläuft in Transportrichtung T schräg zu, so dass sich der Abstand zwischen dem Nutgrund 9a und der Seitenkante des Paneels 6 in Bezug auf die Transportrichtung T stetig verringert.The transport device consists of the three mutually parallel to pulleys 7, 8 circumferentially driven belts 1, 1a, 1b. In the transport direction T are on the belts 1, 1a, 1b driver 2, 2a, 2b arranged regularly spaced. The drivers 2, 2a, 2b protrude over the conveyor belts 1, 1a, 1b in the vertical direction and are aligned parallel to one another in the transverse direction Q. The drivers 2, 2a, 2b engage the rear longitudinal edge of a plate 6 and take the plate 6 so in the transport direction T with. Laterally to the conveyor belt 1, a device consisting of a rail 3 is arranged in the transport path, which has a groove 9 opening in the direction of the belt 1. When the plate 6 is guided past the rail 3, the first groove 5 milled in the side edge of the plate 6 and the groove 9 are opposite the rail 3. In the groove 9, the strip-shaped locking element 4 is inserted. The groove bottom 9a of the groove 3 extends obliquely in the transporting direction T, so that the distance between the groove bottom 9a and the side edge of the panel 6 is steadily reduced in relation to the transport direction T.

In die Nut 9 ist das streifenförmige Verriegelungselement 4 eingelegt. Die Mitnehmer 2 des Bandes 1 sind mit seitlich in Richtung der Schiene 3 hervorragenden Vorsprüngen 2' versehen, die in die Nut 9 der Schiene 3 eintauchen und dabei den Streifen 4 ergreifen und mit derselben Geschwindigkeit wie die Platte 6 in Transportrichtung T transportieren. Durch den schrägen Nutgrund 9a wird der Streifen 4 in der Nut 9 über die Transportstrecke schräg gestellt und mit seinem vorderen Ende 4' beginnend in die Nut 5 der Platte 6 eingeführt und in Transportrichtung T stetig in die Nut 5 eingedrückt, bis es am Ende vollständig in die Nut 5 eingesetzt ist.In the groove 9, the strip-shaped locking element 4 is inserted. The driver 2 of the band 1 are with 3 laterally projecting towards the rail protrusions 2 'provided, which dive into the groove 9 of the rail 3 and thereby grab the strip 4 and transport at the same speed as the plate 6 in the transport direction T. Due to the oblique groove bottom 9a of the strip 4 is placed in the groove 9 over the transport path and inserted with its front end 4 'starting in the groove 5 of the plate 6 and pressed in the transport direction T steadily in the groove 5 until it is complete at the end is inserted into the groove 5.

Die Platte 6 ist an ihren sich gegenüberliegenden Kanten mit identisch ausgebildeten Nuten 5, 15 versehen. Die Fertigung der Platten 6 wird dadurch vereinfacht und das Verriegelungselement 4 kann symmetrisch ausgebildet werden, wodurch die Werkzeugkosten reduziert sind. Das Verriegelungselement 4 kann als Bandmaterial von der Rolle zugeführt und vor der Einrichtung 3 abgelängt werden und dann in der passenden Länge in die Nut 4 eingeschoben werden. Hierzu kann eine nicht näher dargestellte Öffnung in der Oberlippe 3' der Nut 9 vorgesehen sein.The plate 6 is provided at its opposite edges with identically shaped grooves 5, 15. The production of the plates 6 is thereby simplified and the locking element 4 can be formed symmetrically, whereby the tool costs are reduced. The locking element 4 can be supplied as a strip material from the roll and cut to length before the device 3 and then inserted in the appropriate length in the groove 4. For this purpose, an opening not shown in detail in the upper lip 3 'of the groove 9 may be provided.
