Abstract
ABSTRACT OF THE DISCLOSURE
The invention relates to a process for the material recycling of interior panelling parts of vehicles formed from lined wood fibre mouldings, with which it is possible to so work up interior panelling parts of vehicles or the like that from the recovered wood fibre materials of the carrier parts adequately equivalent quality reusable fibrous materials can be obtained, the reusable fibrous materials being highly cleanly separable from the plastic components of the lining and optionally other plastic fittings. The apparatus according to the invention for performing the process is intended to permit particularly economic working. For lossening the wood fibre composite and flexibilizing the wood fibres, the lined moulding undergoes a swelling process, the moulding softened in the wood fibre composite is freed from attached fittings such as clips, retainers, etc., the wood fibre composite is then broken up to directly reusable fibre material and simultaneously the lining is separated from the wood fibre material and materials and lining are separated from one another.

Claims (20)
1. Process for the material recycling of interior panelling parts of vehicles from lined wood fibre mouldings, characterized by the following process steps:
a) the lined moulding undergoes a swelling process for loosening the wood fibre composite and flexibilizing the wood fibres, b) the softened moulding in the wood fibre composite is freed from attached fittings such as clips, retainers, etc., c) the wood fibre composite is then broken up to directly reusable fibrous material, accompanied by the simultaneous separation of the lining from the wood fibre material and finally d) the fibrous materials and the lining are separated from one another.
a) the lined moulding undergoes a swelling process for loosening the wood fibre composite and flexibilizing the wood fibres, b) the softened moulding in the wood fibre composite is freed from attached fittings such as clips, retainers, etc., c) the wood fibre composite is then broken up to directly reusable fibrous material, accompanied by the simultaneous separation of the lining from the wood fibre material and finally d) the fibrous materials and the lining are separated from one another.
2. Process according to claim 1, characterized in that the loosening of the wood fibre composite and the flexibilization of the wood fibres is carried cut by means of water, optionally at elevated temperature.
3. Process according to claim 1, characterized in that the removal of fittings for the moulding takes place by fulling, levelling the moulding or similar bending processes.
4. Process according to claim 1, characterized in that for breaking up the softened wood fibre composite use in made of a fluid with a high flow rate directed onto the wood fibre side of the mouldings.
5. Process according to claim 1, characterized in that the softened wood fibre composite is broken up by mechanical force action.
6. Process according to at least one of the claims 1 to 6, characterized in that the separation of the fibrous material and the lining material takes place by air classification.
7. Process according to at least one of the claims 1 to 5, characterized in that the separation of the fibrous material takes place by screening.
8. Apparatus for performing the process according to claim 1 comprising at least one conveyor means (1, 7, 27), a swelling device (3), a separating device (8) for the fittings (17), a device (9) for breaking up the softened wood fibre composite with simultaneous breaking up of the lining material (12) and a separating means (14, 15, 19) for separating the lining material from the wood fibres (13).
9. Apparatus according to claim 8, characterized in that the device (9) for breaking up the softened wood fibre composite comprises at least one needle roller (10) with an associated clamping device (11), the needle roller exer-ting tensile forces on the lining and the wood fibre composite.
10. Apparatus according to claim 8, characterized in that the separating (3) comprises a water bath.
11. Apparatus according to claim 8, characterized in that the separating device (8) for removing the fittings comprises a multiroll stand.
12. Apparatus according to claim 9, characterized in that the conveyor means (1, 7, 27, 13) are constructed as belt, chain and/or air conveyors.
13. Apparatus according to claim 8, characterized in that the air conveyor for the wood fibre material (13) is operated with heated conveying air
14. Apparatus according to claim 8, characterized in that the separating means for separating the wood fibre material and lining material comprises a revol-ving screen belt (13), with which is associated at its underside and in an at least zonal manner a vacuum tank (14).
15. Apparatus according to claim 8 and 14, characterized in that, in the vicinity of the vacuum tank (14), at least one rotary brush (19) is associ-ated with the top of the screen belt (15).
16. Apparatus according to claim 8, characterized in that the separating means comprises a rotary screening drum.
17. Apparatus according to claim 8 and 16, characterized in that the axis of the rotary screening drum is inclined with respect to the horizontal.
18. Apparatus according to claim 8, 16 and 17, characterized in that at least one vacuum tank is at least zonally associated with the outside of the scree-ning drum.
19. Apparatus according to at least one of the claim 8 to 18, characterized in that the inside of the screening drum has conveying elements in the form of guide surfaces or the like.
20. Apparatus according to at least one of the claims 8 to 18, characterized in that with the inside of the screening drum are associated at least zonally with respect to the drum wall brushes performing a relative movement.
