Abstract

An adhesive machine for constructing segmented rotor blades having at least three prefabricated rotor blade parts contains a first accommodating region for receiving a first prefabricated rotor blade part, a second accommodating region for receiving a second prefabricated rotor blade part and a third accommodating region for receiving a third prefabricated rotor blade part. The first accommodating region, the second accommodating region and the third accommodating region can be moved relative to each other so that, following successful receiving of the three prefabricated rotor blade parts in the proper accommodating regions in an open position of the adhesive machine, the rotor blade parts can be brought into direct or indirect contact with each other via predetermined adhesion regions and thus transferred into an adhesion position.

First claim

The invention claimed is:

1. An adhesive machine for constructing segmented rotor blades each having at least three prefabricated rotor blade parts, the adhesive machine comprising:
accommodating regions, including:
a first accommodating region for receiving a first prefabricated rotor blade part;
a second accommodating region for receiving a second prefabricated rotor blade part; and
a third accommodating region for receiving a third prefabricated rotor blade part, said first accommodating region, said second accommodating region and said third accommodating region being movable relative to each other in such a way that, after the three prefabricated rotor blade parts have been received in respective ones of said accommodating regions in an open position of the adhesive machine, the prefabricated rotor blade parts are brought into direct or indirect contact with each other along predetermined adhesion regions, and thus transferred into an adhesion position, said first accommodating region and said third accommodating region being movable toward one another and toward the second accommodating region while the second accommodating region remains spatially fixed in place, said second accommodating region being disposed between said first accommodating region and said third accommodating region.

2. The adhesive machine according to claim 1 , further comprising at least one additional, fourth accommodating region, configured to receive or mount a flange, which can be adhesively bonded with at least one of the three prefabricated rotor blade parts over a predetermined adhesion region.

3. The adhesive machine according to claim 2 , wherein at least one of said first, second, third and fourth accommodating regions can be tilted relative to one other one of said accommodating regions while transferring the prefabricated rotor blade parts situated in said accommodating regions into the adhesion position.

4. The adhesive machine according to claim 1 , wherein said first accommodating region, said second accommodating region and said third accommodating region execute a movement relative to each other that is perpendicular to a progression of a gravitational field while transferring the prefabricated rotor blade parts situated in said three accommodating regions into the adhesion position.

5. The adhesive machine according to claim 1 , wherein at least one of said three accommodating regions is pivotable in design.

6. The adhesive machine according to claim 2 , wherein at least one of said accommodating regions can be adjusted to a geometric shape of the prefabricated rotor blade part or the flange provided as intended for accommodation.

7. The adhesive machine according to claim 1 , wherein at least one of said first, second or third accommodating regions of the adhesive machine exhibit a longitudinal extension, which is generally oriented parallel to a longitudinal extension of a rotor blade to be constructed.

8. The adhesive machine according to claim 1 , further comprising an adhesive apparatus, which can at least sectionally move along the predetermined adhesion regions, in particular perpendicular to a directional progression of earth's magnetic field along the predetermined adhesion regions.

9. The adhesive machine according to claim 2 , further comprising at least one tempering device configured to expose the predetermined adhesion regions of at least one of the prefabricated rotor blade parts or the flange to heat on a locally limited basis.

10. The adhesive machine according to claim 2 , further comprising at least one pressing unit configured to be able to press at least one end of the prefabricated rotor blade parts against the flange for purposes of adhesive bonding.

11. The adhesive machine according to claim 1 , further comprising at least one suction unit for retaining at least one of the prefabricated rotor blade parts in a respective one of said accommodating regions under a vacuum.

12. The adhesive machine according to claim 1 , wherein at least one of said three accommodating regions is pivotable in design and can pivot by at least 90°.

13. A method for adhesively bonding several prefabricated rotor blade parts for constructing a segmented rotor blade, which comprises the steps of:
adhesively bonding the prefabricated rotor blade parts by means of an adhesive machine according to claim 1 , such that at least one of the prefabricated rotor blade parts are accommodated by the adhesive machine, and brought into direct or indirect contact with another of the prefabricated rotor blade parts along predetermined adhesion regions so as to be adhesively bonded in an adhesion position.

14. The method according to claim 13 , wherein the three prefabricated rotor blade parts are accommodated by the adhesive machine.

15. The adhesive machine according to claim 1 , wherein at least one of said first, second, third accommodating regions can be tilted relative to one other one of said accommodating regions while transferring the prefabricated rotor blade parts situated in said accommodating regions into the adhesion position.

16. The adhesive machine according to claim 1 , wherein at least one of said accommodating regions can be adjusted to a geometric shape of the prefabricated rotor blade part or the flange provided as intended for accommodation.

17. The adhesive machine according to claim 1 , further comprising at least one tempering device configured to expose the predetermined adhesion regions of at least one of the prefabricated rotor blade parts or the flange to heat on a locally limited basis.

18. The adhesive machine according to claim 1 , further comprising at least one pressing unit configured to be able to press at least one end of the prefabricated rotor blade parts against the flange for purposes of adhesive bonding.
