Abstract

A direct SMC production device includes an impregnation device for impregnating fibers of a material strand. The impregnation device includes at least one densification unit which is designed to densify the material strand after application of the strand to at least one substrate.

Claims

1. A direct SMC production device having an impregnation device (12) for impregnating fibers of a material strand (14), characterized in that the impregnation device (12) has at least one densification unit (16) which is provided for the densification of the material strand (14) after application of the latter onto at least one carrying element (18, 20).

2. The direct SMC production device as claimed in claim 1, characterized in that the densification unit (16) is formed by a rolling unit (22).

3. The direct SMC production device as claimed in claim 2, characterized in that the rolling unit (22) has at least two adjustable rolling elements (24, 26, 102, 104, 106, 108, 110).

4. The direct SMC production device as claimed in claim 3, characterized in that the impregnation device (12) has a control and/or regulation unit (28) which is at least provided for adjusting the at least two rolling elements (24, 26, 102, 104, 106, 108, 110) of the rolling unit (22) in dependence on at least one production parameter.

5. The direct SMC production device as claimed in at least claim 2, characterized in that at least one rolling element (24, 26, 102, 104, 106, 108, 110, 144, 146, 148, 150, 152, 154, 156) of the rolling unit (22) has a guide recess (30) for guiding the material strand (14) and/or a conveyor element (32, 80).

6. The direct SMC production device as claimed in one of the preceding claims, characterized in that the densification unit (16) comprises a main direction of extent (34) which, in an operating state, is oriented at least substantially in the vertical direction (36).

7. The direct SMC production device as claimed in one of the preceding claims, characterized by a temperature setting unit (38) which is at least provided for controlling the temperature of at least one Conveyor element (32, 80) of the impregnation device (12).

8. The direct SMC production device as claimed in one of the preceding claims, characterized by a cooling device (40) at least for cooling the material strand (14), said cooling device (40) being arranged downstream of the impregnation device (12) in a direction of transport (42) of the material strand (14).

9. The direct SMC production device as claimed in claim 8, characterized in that the cooling device (40) has at least one cooling plate element (44) over which the material strand (14) is conveyed in the direction of transport (42) of the material strand (14).

10. The direct SMC production device as claimed in at least claim 8, characterized in that the cooling device (40) has at least one cooling roller element (46, 160, 162, 164, 166, 168, 170) which is at least partially wrapped by the material strand (14).

11. The direct SMC production device as claimed in one of the preceding claims, characterized by at least one first fiber feeding device (48) and one second fiber feeding device (50) which are provided for feeding cut fibers to at least one carrying element (18, 20).

12. The direct SMC production device as claimed in at least claim 10, characterized in that the first fiber feeding device (48) is provided for feeding cut fibers to a first carrying element (18) and the second fiber feeding device (50) is provided for feeding cut fibers to a second carrying element (20) which, at least in an operating state, is formed separately from the first carrying element (18).

13. The direct SMC production device as claimed in at least claim 10 or 11, characterized by at least one first fiber cutting device (52), which is assigned to the first fiber feeding device (48), for cutting at least one continuous filament (54) into cut fibers, and at least one second fiber cutting device (56), which is assigned to the second fiber feeding device (50), for cutting at least one continuous filament (90) into cut fibers.

14. The direct SMC production device as claimed in one of the preceding claims, characterized by at least one continuous filament feeding device (58, 92) which is at least provided for feeding continuous filaments (54, 90) to a fiber cutting device (52, 56) by means of a fluid flow.

15. A method for producing resin mats made from fiber-reinforced polymer, in particular by means of a direct SMC production device (10) as claimed in one of the preceding claims, characterized in that a material strand (14) is densified by a densification unit (16) of an impregnation device (12) after application of the strand onto at least one carrying element (18, 20).
