Abstract

A manufacturing arrangement realized for the manufacture of a rotor blade, including a pair of tracks arranged along the longitudinal sides of a blade mold, a first gantry assembly realized to span the track pair and to carry a first tool arrangement, which first tool arrangement includes at least a fiber distributor, a second gantry assembly realized to span the track pair and to carry a second tool arrangement, and a control arrangement realized to effect a coordinated movement of the gantry assemblies along the track pair and to coordinate the operation of the second tool arrangement with the operation of the first tool arrangement, is provided. A manufacturing line, a method of manufacturing a rotor blade, and a wind turbine rotor blade are further provided.

First claim

The invention claimed is:

1. A manufacturing arrangement for the manufacture of a rotor blade, comprising:
a pair of tracks arranged along longitudinal sides of a blade mold;
a first gantry assembly configured to span the pair of tracks and to carry a first tool arrangement, the first tool arrangement comprising at least a fiber distributor;
a second gantry assembly configured to span the pair of tracks and to carry a second tool arrangement; and
a control arrangement configured to effect a coordinated movement of the first gantry assembly and the second gantry assembly along the pair of tracks and to coordinate an operation of the second tool arrangement with an operation of the first tool arrangement.

2. The manufacturing arrangement according claim 1 , wherein the fiber distributor is configured to distribute a fiber material into the blade mold.

3. The manufacturing arrangement according to claim 1 , wherein the first tool arrangement comprises a first magazine for storing a fiber material of a first type.

4. The manufacturing arrangement according to claim 3 , wherein the second tool arrangement comprises a second magazine for storing the fiber material of a second type.

5. The manufacturing arrangement according to claim 1 , wherein the second tool arrangement is configured to provide a fiber material to the first tool arrangement.

6. The manufacturing arrangement according to claim 1 , comprising a fiber handling arrangement configured to select a specific fiber material and/or to cut a specific length of a fiber material and/or to load a tool attachment of the fiber distributor with a quantity of the fiber material.

7. The manufacturing arrangement according to claim 1 , wherein the first tool arrangement is configured to at least partially traverse its gantry.

8. The manufacturing arrangement according to claim 1 , wherein the control arrangement comprises a drive unit arranged on a gantry for moving the gantry along the pair of tracks and/or an actuating unit for actuating a the first tool arrangement.

9. The manufacturing arrangement according to claim 1 , comprising a track supporting structure for supporting the tracks of the pair of tracks such that a height of the tracks exceeds a height of the blade mold.

10. A manufacturing line for the manufacture of wind turbine rotor blades, the manufacturing line comprising:
a first manufacturing arrangement according to claim 1 for manufacturing an upper blade half, wherein the pair of tracks is arranged along the longitudinal sides of an upper blade mold; and
a second manufacturing arrangement for manufacturing a lower blade half, wherein the pair of tracks is arranged along the longitudinal sides of a lower blade mold;

wherein control arrangements of the first manufacturing arrangement and the second manufacturing arrangement are configured to coordinate an operation of the tool arrangements such that the upper blade half and the lower blade half are manufactured simultaneously.

11. The manufacturing line according to claim 10 , wherein the pair of tracks of each of the first manufacturing arrangement and the second manufacturing arrangement are arranged to accommodate a plurality of blade molds arranged sequentially between the pair of tracks.

12. A method of manufacturing a rotor blade, the method comprising the steps of:
(A) arranging a pair of tracks along longitudinal sides of a blade mold;
(B) arranging a first gantry assembly to span the pair of tracks and placing a first tool arrangement on the first gantry assembly;
(C) arranging a second gantry assembly to span the pair of tracks and placing a second tool arrangement on the second gantry assembly; and
(D) operating a control arrangement to effect a coordinated movement of the first gantry assembly and the second gantry assembly along the pair of tracks and to coordinate an operation of the second tool arrangement with an operation of the first tool arrangement.

13. The method according to claim 12 , wherein the control arrangement is operated to control a fiber handling arrangement of the second tool arrangement to feed a specific length and/or a specific quantity of a fiber material to a tool attachment.

14. The method according to claim 12 , wherein the control arrangement is operated to move the first gantry assembly and the second gantry assembly from a root end (M root ) of the blade mold to a tip end (M tip ) of the blade mold.

15. The method according to claim 12 , wherein the control arrangement is operated to control the first gantry assembly and the second gantry assembly and/or the first tool arrangement and the second tool arrangement on a basis of a position of a gantry assembly relative to the rotor blade mold.

16. A wind turbine rotor blade manufactured using the method according to claim 12 .
