Abstract

Apparatus for laying filament reinforced tape in a form, cutting same to a predetermined pattern and molding same in a preferred form.

Claims

1. An automated, integrated composite laminating production line comprising:

parallel rail means of a predetermined length;

a taping gantry controllably moveable along said rail means, said gantry mounting a tape head;

a first work table within said rail means and oriented to said tape gantry to receive tape therefrom in composite lamination of a tape from said tape head;

a second work table spaced from said first work table within said rail means said second work table having a pivotal surface;

a transfer gantry controllably moveable along said rail means;

a means supported by said transfer gantry to transfer product from said first work table to said second work table;

a mold form adjacent said second work table;

a cutting gantry controllably moveable along said rail means;

cutting means supported by said cutting gantry to size the composite lamination on said second work table, said pivotal surface of said second work table cooperating with said cutting means; and

control means to move the tape, transfer and cutting gantries and operate the pivoting surface.

2. The apparatus of claim 1 and further characterized in that said second table is adapted to function as a means to store said composite laminations that have been sized for curing a structure thereon.

3. The apparatus of claim 1 wherein the cutting means is a laser means mounted to move across said cutting gantry as it moves along said rails.

4. The structure of claim 3 wherein the second work table is such as to reflect the laser beam and prevent damage to said second work table.

5. A second work table according to claim 1 and further characterized by:

a fixed support;

a modular vacuum supporting surface, said surface having a reflective finish so as to preclude damage thereto as by high intensity cutting beams;

a means to support the surface on said table, said means including sideward actuation devices to move said surface laterally of said line, said means further including rotary actuator means to permit said surface to transfer articles thereon to the side of said line.

6. The structure of claim 5 and further comprising means to forceably project articles along an area less than the whole thereof while holding the remainder of the article.

7. The apparatus of claim 6 wherein the means to forceably project is a bar between various modules of the modular vacuum supporting surface that is projectable a limited amount from its flush, rest station coterminous with the surface.

8. A production line according to claim 1 wherein the taping, transfer and cutting gantry are each further characterized as:

a frame having side legs, spacers to adjust longitudinal spacing of the side legs and a platform supported by said legs;

means to mount devices to said platform to be movable within said frame; and

means operatively arranged in at least some of said side legs to give controllable motion to said gantry.

9. The transfer gantry of claim 8 wherein the devices on said platform are characterized as a means to transfer composite structures from one assembly station to another, said means including a vacuum surface supported from said platform and movable relative thereto and a vacuum drawing means operatively associated with said surface.

10. The apparatus of claim 9 wherein the means to transfer includes devices on each end to grip sheet material and hold same during movement of said means.

11. The taping gantry of claim 8 wherein the devices on said platform are a composite tape laying and sizing device.

12. The structure of claim 11 wherein the composite tape laying and sizing device includes a rotatable support from said platform for a housing having a tape feeding roll for tape with a separator backup, a tape laydown means and a separator take-up reel.

13. The cutting gantry of claim 8 wherein the devices on said platform are characterized as a laser operatively associated by means to the platform to provide a cutting laser beam movable with and within the cutting gantry to cut a desired pattern of the lamination.

14. The apparatus of claim 13 wherein the laser is fixed to the platform and a system of mirrors is used to provide the laser cutting beam to a movable head directing said cutting beam downwardly, said movable head being slideable along rod means supported by said platform.

15. The apparatus of claim 1 and further comprising means to provide a carrier material for said first work table, said means cooperating with said transfer gantry to permit application of said carrier material prior to lay-up and upon transfer of the composite lamination.

16. The apparatus of claim 15 wherein the carrier material for said first work table is a coil of paper adjacent the first work table.

17. The apparatus of claim 15 wherein the cutting means is a laser means mounted to move across said cutting gantry as it moves along said rails.

18. The structure of claim 17 wherein the second work table is such as to reflect the laser beam and prevent damage to said second work table.

19. The apparatus of claim 15 and further comprising means to provide a carrier, and broadgood materials for said second work table, said means cooperating with said transfer gantry to permit application of said materials on said second work table in between receipt of the composite lamination by said second work table.

20. The apparatus of claim 19 wherein the carrier material for said first work table is a roll of polyethylene film at one end of said rail means and said means to provide a carrier material for said second work table is a roll of polyethylene film at another end of said rail means with said transfer gantry reciprocal therebetween.

21. The apparatus of claim 19 wherein the cutting means is a laser means mounted to move across said cutting gantry as it moves along said rails.

22. The structure of claim 21 wherein the second work table is such as to reflect the laser beam and prevent damage to said second work table.

23. The apparatus of claim 19 wherein the carrier material and the broadgoods materials are characterized as a bleeder cloth such as slipsheets, peel plys and bleeder plys.

24. The apparatus of claim 23 wherein the pivotal surface of said second work table has means to move it laterally and to rotate it so that said surface will transfer patterned items therefrom to said mold form.

25. The apparatus of claim 24 wherein the mold form is a table adjacent and to the side of said second work table to receive said patterned items therefrom.

26. The apparatus of claim 19 wherein the means supported by said transfer gantry includes a means to draw a vacuum at the surface receiving the composite lamination.

27. The apparatus of claim 26 wherein the cutting means is a laser means mounted to move across said cutting gantry as it moves along said rails.

28. The structure of claim 27 wherein the second work table is such as to reflect the laser beam and prevent damage to said second work table.
