Embodiment Construction

[0043] figure 1 Shown is a loading device 1 for loading rolls 2 of fiber-based sheet material onto an application unit 3 for producing not-shown fiber-reinforced parts, such as blades for wind power plants. The loading device 1 comprises a frame 4 on which a lifting mechanism 5 is displaceably arranged in the vertical direction. On the lifting mechanism 5, the swivel mechanism 6 is arranged rotatably around a horizontal swivel axis 7 and comprises a first gripper 18 adapted to releasably grasp the shaft end 9 of the first roll 2a and a first gripper 18 adapted to releasably The second gripper 19 grips the shaft end 10 of the second roll 2b. It should be noted that in figure 2 and image 3 In , the first and second rolls 2a, 2b are shown by means of empty rolls, so that only the shafts 11 of the rolls are shown. The shafts 11 may be so-called air shafts adapted to be expanded by means of air pressure, thus securing the inner tube of the roll, not shown, to the shaft. Howe...

Abstract

The loading apparatus (1) for loading rolls (2) of fibre based sheet material to an application unit for the production of fibre-reinforced parts comprises a frame (4) on which a lift (5) is arranged displaceably in vertical direction and is adapted to carry at least one roll (2). The lift (5) comprises a swivel mechanism (6) arranged rotatably about a swivel axis (7) and comprising at least first grippers (18) adapted to releasably grip shaft ends (9) of a first roll (2a) and second grippers (19) adapted to releasably grip shaft ends (10) of a second roll (2b). A method of loading rolls is also disclosed.

Description

technical field [0001] The invention relates to a loading device for loading rolls of fiber-based sheet material onto an application unit for the production of fiber-reinforced parts such as blades for wind power plants, the loading device comprising a frame on which A lifting mechanism is displaceably arranged in a vertical direction and adapted to carry at least one roll of fiber-based sheet material. Background technique [0002] In the production of blades for wind power plants, an application unit in the form of a bridge is usually used to unroll and position the fiber-based sheet in an open mould, whereby the application unit is on rails during application of the sheet Traveling, the track includes rails placed at either side of the open mold. In this way, the roll of sheet material placed on the bridge can be moved over and along the open mould. When a roll of sheet material is exhausted or has to be replaced by another roll for other reasons, for example because an...
