Method and device for producing a plate-shaped c2Π component

809885/0731

ORIGINAL INSPECTED

The invention relates to a method for producing a plate-shaped Sau elements, such as an inner panel, a partition, a filling board o arranged plate is arranged on the upwardly facing surface of a rib grating for stiffening the component and an adhesive filling compound, such as a synthetic resin foam, in the spaces delimited by the plate and the stiffening ribs, is brought in "

Such plate-shaped components are known and can be found on many uses, e.g. B. as inner shell panels, partition walls, filler panels, etc.

Any suitable adhesive filling compound can be used as the filling compound. Very good for this purpose is z. B. an adhesive synthetic resin foam, such as polyurethane foam, is suitable. At the stiffening ribs the foam is applied in a thicker layer on the plate so that the sides of the ribs, which have a height of e.g. B. have 6 cm, be absorbed in the foam mass and be well connected to it. In the remaining places, the foam is in a thinner layer with a strength of z. B. 3.5 cm attached to the plate. The foam forms a heat-insulating layer there.

Such components are preferably based on a so-called "module system" constructed, d. that is, the spacing between the ribs is a multiple of a chosen fixed size, e.g. ß. a multiple of 10 cm, hereinafter referred to as "module". The first manufacturing phase of the component is, inter alia, in the not yet published

NL patent application 7707841 dated July 14th, 77 .

So far, one problem has been that which is expedient and as extensive as possible automatic introduction of the filling compound into the spaces between the ribs. In the NL - patent application. 7503382 is already given a solution to this problem. However, this solution has not proven to be entirely appropriate, since it is an intermittent one Movement of the elements is impractical and the angles between the ribs and the plate difficult to fill in in the manner indicated is executable.

It has been found that in the NL patent application. 7503382 Entered procedures are simpler, but still just as expedient can be"

The invention is based on the object of a method of the introductory part to create mentioned type, which does not adhere to the aforementioned disadvantages, which can rather be carried out very easily and to components leads that have no irregularities or damaged areas.

This object is achieved according to the invention in that the plate with the stiffening grid is uniformly under a spray head for strip-wise introduction of the filling compound into the rib spaces, the spray head moved from one side of the component to the other moved back and forth at a distance from and parallel to the previous track and quickly after introducing a strip of filling compound by a strip width of the direction of movement of the component

shifted against and then a next strip of filling compound is then introduced into the rib grille immediately on the preceding strip. This is how you get to one Method of the type mentioned in the introduction, which fully fulfills the aforementioned object of the invention.

According to a further feature of the invention it is provided that the component is built according to a modular system, the stiffening ribs are arranged on a module and with the help of the spray head filling compound with a strip width of 1/3, 1/2, 2/3, 3 / Ί , 3/2 or a multiple of the module between the stiffening rib: η is attached. Advantageously, the Streifenbreito ~ he filler mass equal to or nearly equal to the module size is kept »Kz is advisable to attach the leader strip filling material viewed in the movement direction of the component at the rear of a rib and the end strip material filler at the front of the neighboring rib.

The invention also relates to a plate-shaped component with a plate and a rib grating arranged on the plate using mutually parallel ribs. This Component is characterized according to the invention in that the space delimited on one side by the plate and the ribs with a Resin foam such as polyurethane foam are filled.

The invention also relates to an implementation device the procedure described above. This device is characterized by a roller conveyor for uniform movement a plate with a rib grating arranged thereon and

moved in the same direction by one arranged above the roller conveyor Bridge with a spray head mounted movably transversely to its direction of movement, the bridge and the spray head so closed are to control that filler to be applied in strips with a defined width on the component located on the roller conveyor

A spray head is to be understood as a means that mixes with any one In a manner, e.g. by pouring, spraying or blowing, the filling compound is applied. B. glass wool with an adhesive, although resin foam is preferred.

liil the distance between the ribs from center to center is the ■■ - ■ röche dos module and the free space is therefore the n-fold of the c-iw'ls minus the thickness of a rib, with the correct meal it is r. :: Ersite the filling compound strips to be sprayed on, it is possible to apply a little more filling compound in the 1 v. If the dimensions are correct, the same result can be achieved in a much simpler way than with the known methods. In addition, the spray head, which can be moved in two directions, can be more easily adapted to the starting position of the component that is moving uniformly. In the NL - patent application. 7503382 also mentions that the spray head can perform two movements, but the intermittent advancement of the component remains a necessary evil.

The method according to the invention is illustrated in more detail with the aid of the drawing
