The invention relates to a method and apparatus for mechanically producing a door leaf, with an insert for insulation and / or stabilization, wherein the door leaf is coated with door cover plates comprising a frame formed of longitudinal latch and cross bars, in which the material for insulation and / or Stabilization existing insert is introduced, and which is coated with the insert to form a door leaf on both sides with door top panels using an adhesive.

State of the art

Door leaves with different surfaces are known from the prior art. The mechanical requirements for a door are different here, in which case the choice of the insert for the door version is essential. Known door leaves here consist of longitudinal and transverse bars, which form a peripheral, outer frame on the door leaf and wherein the frame is covered with so-called door cover panels. The cavity forming in the frame is in this case filled with differently formed materials, which on the one hand are used to insulate but on the other hand also to stabilize the door leaf.

For example, deposits with different door leaf weights are known. The lightest versions here are inserts that consist of honeycombs, which are formed from tight-sized cardboard. Another easy-to-build door panel insert is designed in such a way that tubular band strips or so-called continuous chipboard chips are introduced into the door panel. Another version includes the heavy building door leaves whose deposits are made of solid chipboard or solid chipboard. The last-mentioned door variants have a high stability here, which meets the corresponding demands.

That's how it describes FR 1.187.463 a manufacturing method for producing a door which is formed from longitudinal profile elements, between which a flexibly held insert / intermediate layer is inserted or incorporated. It is also described in the document that surfaces are glued or attached to the side surfaces to create the door leaf, and here on the zig-zag-like insert.

As a further prior art document, U.S. Patent No. 5,348,259 discloses GB 444,218 an improvement made on a door. The improvements are essentially to be seen in that two cover surfaces are provided, on the inside of which ribs or longitudinal or transverse bars are arranged, which are fastened to the cover plates, wherein flexibly held inserts are provided, in particular a deformation or a to avoid relative expansion between the longitudinal or transverse bars.

The DE 10 2009 001 245 A1 discloses a hollow chamber element and the method for producing this hollow chamber element. The hollow chamber element is used for the furniture industry as a plate element use, whereby the use is proposed for room doors. In order to improve the static properties, spaced apart clamping frame elements with a honeycomb structure spanned therebetween are provided in the plate element.

According to another document of the prior art is in the WO 2005/003499 A1 a method and an apparatus for producing a door are described. The method described and the device in this case include the production of a door leaf with a flexibly held from a honeycomb insert insert with end attaching cross sections, which are pulled apart between two longitudinal profiles, so that a frame formed of longitudinal bars and cross bars results in which the existing material for insulation and / or stabilization insert is involved. The frame with the insert is coated on both sides with Türdeckplatten using an adhesive to form a door leaf.

A disadvantage of these known from the prior art doors or door leaves, it is considered that they make the production process very expensive, which is associated with a corresponding cost. Furthermore, it is considered disadvantageous that on the one hand the easy-to-build door leaves do not have the sufficient stability, on the other hand, the massive heavy door leaves build their cost structure ago very expensive.

The FIG. 1 a shows the representation of a skeleton 6, which according to the inventive method comprises the production of a door and here in particular a door leaf 1 with an insert 2 for insulation and / or stabilization, wherein the door leaf 1 is coated with door cover plates 3. According to the method of the invention are in a first step, shown in the FIG. 1a , Parallel arranged transverse profile elements 4 placed at a distance, in each case at the end of the profile elements 4 respectively longitudinally arranged profile elements 5 are pressed and connected to the ends of the transverse profile elements 4, so that a skeleton 6 results. It goes without saying that even an arrangement that is not here Inventive method according to a second embodiment Fig. 1b of connected at a distance longitudinal profile elements 5 with each top and bottom end arranged transverse profile elements 4 can produce a skeleton 6. The skeleton 6 thus produced is then ground to size in a second step, so that the front and the back of the skeleton 6 have flat surfaces. Optionally, the interstices in the skeleton 6 can be filled with an insert 2 before grinding.

The skeleton 6 is then conveyed through a glue applicator, so that the front and the back of the skeleton 6 are wetted with glue or glue for mounting the cover plates 3, as shown in FIG FIG. 2 is shown. This method requires no press, as was the case in the prior art. The adhesive connection is made by means of the adhesive below room temperature without the need for a separate pressure or pressing device. Here, the cover plates 3, for example, consist of non-woven or paper. On the surfaces of the cover plates 3 then glue strips 8 are applied, as these in the FIG. 2 are shown in the front view. On the door panel 1 thus created are finally applied decors 7, which are not shown here. Like in the FIG. 2 can be seen, four glue strips 8 are provided here, with three or two glue strips are sufficient to attach here the decoration application on the surface.

To connect the transverse profile elements 4 4 pins 9 are milled at the ends of the transverse profile elements, as this particular in the FIGS. 3 and 4 can be seen, which can be inserted into milled grooves 10 on the longitudinally disposed profile elements 5. Due to this tongue and groove connection between the longitudinal and transverse profile elements 4, 5, there is also the possibility that the transverse profile elements 4 can be displaced in the groove 10 of the longitudinal profile element 5, so that correspondingly alignment of the transverse profile elements 4 in the skeleton 6 can be made.

The FIG. 3 shows the integration of a lock with strike plate 11 in a lock pocket, on which arranged opposite the pivot joint longitudinal profile element 5, in which case a so-called inner longitudinal profile element 12 is attached to one of the longitudinal profile elements 5. In particular from the FIG. 4 It can be seen that the inner longitudinal profile element 12 is inserted into the groove 10, wherein on one side of the inner longitudinal profile 12 also a pin 9 and on the opposite side a groove 10 is provided so that then engage in the groove 10 corresponding to the transverse profile element 4 can. On the basis of this design, a reinforcement is created, in particular in the area of the lock pocket, which in particular has the sufficient material to engage therein a strike plate 11 with the lock.

According to a particularly advantageous embodiment of the invention, shown in the FIG. 5a and in the FIG. 5b , The longitudinal profile elements 5 can be made of sub-profile elements 5.1 and 5.2 plugged into one another, so that the door or the door leaf 1 is halved by its transport volume. The FIG. 5a shows in particular in the area of the lock pocket a doubling of the transverse profile elements 4, wherein the FIG. 5b a tripling of the transverse profile elements 4 in this area shows. For connection of the partial profile elements 5.1 and 5.2, a tongue and groove connection is provided which, like the mutually parallel transverse profile elements 4 are firmly connected to a glue or an adhesive.

The object of FIGS. 6 and 7 , which is not part of the invention, respectively shows a schematic representation of an open door leaf 1 with an insert 2 according to the prior art. The door leaf 1 with the insert 2 in this case comprises a frame formed from longitudinal bars 5 and 4 crossbars frame 19. In the frame 19 which consists of different material for insulation or stabilization insert 2 is arranged according to the prior art. The frame 19 with the insert 2 is then provided on both sides with door cover plates 3 to form the door leaf 1. It is indicated here in the plan view, only one door cover sheet 3, which lies on the back of the door presentation.

Like from the FIGS. 6 and 7 can be seen in the synopsis, the insert 2 according to the prior art consists of a flexibly held composite 20 of profile elements 21. The profile elements 21 are connected to each other with stretchable elements 22. The profile elements 21 in this case preferably consist of wooden strips or wooden rods. The flexibly connected profile elements 21 are aligned in the frame 19 formed by longitudinal and transverse bars 4 4 in the longitudinal direction to the door leaf level, shown in the FIG. 6 , or in transverse orientation to the door leaf level, shown in the FIG. 7 , usable. In the synopsis of FIGS. 6 and 7 It can be seen that with the so-called. Transverse alignment to the door leaf level, shown in the FIG. 7 , the flexible insert 2 here causes a much more stable composite effect, since the parallel horizontal profile elements 21 here extend over the entire surface of the door panel 1. The use, whether transverse or longitudinal orientation depends primarily on how high the load factor of the door panel 1 should be interpreted.

The profile elements 21 are connected to each other, for example, with a formed from honeycomb structure 23 according to the prior art. In this case, the honeycomb structure 23 is formed extendable or collapsible, as in particular in the FIGS. 8 and 9 is clearly visible. In the FIG. 8 the honeycomb structure 23 is shown in the extended situation, wherein in the FIG. 9 the honeycomb structure 23 is shown in the collapsed situation. From this it can be seen that, especially in the collapsed situation, the insert 2 is very small in construction because it ultimately unfolds its surface stabilization effect in the solid situation. Here, the known honeycomb structure 23 is preferably made of paper or paperboard, wherein the insert may also consist of plate-like components.

Like from the FIGS. 6 to 9 , State of the art, can be seen, the known honeycomb strips 23.1 are preferably attached to each end of the profile elements 21. This results in a concertina-like insert 2, which can be pulled out tilt-safe in the frame 19 of the door panel 1. As in particular from the FIGS. 6 and 7 can be seen, arise between the honeycomb strip 23.1 in the extended state so-called. Hollow spaces, in which case they can be filled with filler, which in this case may for example consist of paper or wool or other materials. It is also conceivable that these cavities can also be provided with honeycomb stripes, so that the insert 2 consisting of profile element 21 and honeycomb strip 23.1, the entire cavity surface of the door panel 1 lines or fills.

In the FIGS. 10a, b and 11 Profile elements 21 are shown, the ends provided with pins 9 to form a tongue and groove connection in FIG. 10b or a dovetail joint in FIG. 10a are provided with the transverse bars 5 arranged transversely thereto. It goes without saying that the illustrated tongue and groove connection can also be aligned in the opposite direction.

It goes without saying that it is now possible to easily and easily attach or thread the flexibly held insert 2 according to the prior art to the grooved longitudinal bar 5, wherein then in the threaded state the insert 2 can be pulled apart along the longitudinal bar 5 , In this case, the profile elements 21 can then be firmly connected to the longitudinal bars 5, so that the insert 2 forms the skeleton 6 of the door leaf 1, which ultimately gives the door a high stability. To complete the door leaf, it then only requires that the top and bottom of the skeleton 6 are coated. Of course, a skeleton 6 can be created with grooved crossbars 4, in which case the profile elements 21 would be arranged vertically in the door leaf 1.

So that there is no dynamic pressure in the interior of the insert 2, the profile elements 21 are provided on the top and / or bottom with ventilation slots 24, which allow a natural internal ventilation of the door 1, shown in the FIG. 11 ,

The FIG. 12 shows in plan view an assembly line for the production of the door leaf according to the invention 1. As shown in FIG. 12 can be seen, first takes place by means of grippers 26 from a warehouse, the removal of the insert 2, which is in a plate-like shape. The plate 2 is then pushed onto a milling or saw table 27, so that the insert 2 is then divided into equal stress-free parts. In the milled gap areas 28, which were generated by the milling 29, the cross bar 4 are inserted from a magazine, in each case also corresponding end crossbars 4 are recognized. In a further step, a milling 30 is then made on the longitudinal sides, which mills out in particular the pin shape in the long sides. Thereafter, the milling 31 of the longitudinal bar 5, which are provided here with a groove 10. Then in a further station 32, the longitudinal bars 5 are pressed with their groove shape on the created pin shape, then in a further station 33 accordingly a reprint can take place, so that in this way the skeleton 6 is created with the deposits 2.

Then we pushed the prefabricated door leaf 1 to a transfer station 34, which, after passing through the transition station 34, a grinding device 35 is subjected. Here, a calibration is first made from below, with roll grinder or roller grinder grind the door leaf 1 exactly to measure. Thereafter, the grinding takes place from the top, so that then also the door panel 1 is calibrated at the top. The thus finished door leaf 1 is then spent in a magazine 36.

The magazine 36 can then according to another station 37, as this example in the FIG. 13 is shown, where the according to the FIG. 12 finished door leaf blank is coated. There will be then applied in a spray 38, the adhesive, and applied in a coating station 39, the decor 7. Subsequently, pressure rollers 40 can press the applied decor 7, so that a uniform surface contact of the decor 7 is given before the finished door leaf 1 is stored again in a magazine 36.
