Abstract

Exemplary embodiments generally relate to a method and device for assembling a plurality of different roof-covering membranes, herein known as fitments. The particular fitment is preferably designed for the particular roof on which it is to be used. The roof measurements may be provided to a factory which may create a unitary membrane from separate pieces which may be hot air bonded together. A single machine may be utilized to quickly, and repeatably assemble a plurality of different fitments.

Claims (69)

1. A device for assembling roof fitments comprising

a bolster comprising:

two substantially flat areas,

a curved area, and

one or more securing mechanisms;

a ram located above said bolster and comprising:

a first die controlled by a main ram actuator assembly,

a second die having a concave feature corresponding to the curved area of the bolster and controlled by an auxiliary actuator assembly; and

one or more suction devices on the first die; and

a horizontally-retractable heating element between said bolster and said ram.

2. The device from claim 1 further comprising:

one or more suction devices on the two substantially flat areas of the bolster.

3. The device from claim 1 further comprising:

one or more locating pins on the first die of the ram.

4. The device from claim 1 further comprising:

a plurality of hot air exhausts along said heating element.

5. The device from claim 1 further comprising:

one or more inserts on the first die.

6. The device from claim 5 wherein:

the inserts are interchangeable with other inserts of varying geometries.

7. The device from claim 1 wherein:

the heating element is interchangeable with other heating elements of varying geometries.

8. A method for assembling a roof fitment comprising the steps of:

1. placing a top membrane portion on a bolster plate;

2. placing a base membrane portion on the bottom surface of a ram having an insert, wherein at least a portion of said top and base membranes overlap each other and also a portion of the insert;

3. holding said top membrane portion in place using one or more securing mechanisms;

4. holding said bottom membrane portion in place using one or more suction devices;

5. forcing hot air over the overlapping areas of both the top and base membranes; and

6. pressing at least a portion of the overlapping membrane areas together.

9. The method from claim 8 wherein the step of holding the bottom membrane portion in place further comprises the step of:

holding the bottom membrane portion in place using one or more locating pins.

10. The method of claim 8 wherein the step of holding the top membrane portion in place further comprises the step of:

holding the top membrane portion in place using one or more suction devices.

11. The method of claim 8 wherein the step of pressing at least a portion of the overlapping membrane areas together further comprises the steps of:

aligning edge features of the ram with the overlapping membrane areas; and

compressing the overlapping membrane areas between the bolster and the edge features of the ram.

12. The method of claim 11 further comprising the step of:

pressing a concave feature of the ram into a corresponding curved area of the bolster.

13. The method of claim 8 further comprising the steps of:

removing the assembled roof fitment;

replacing the insert with a second insert having different geometry;

placing a second top membrane portion on the bolster plate;

placing a second base membrane portion on the bottom surface of the ram containing the second insert, wherein at least a portion of the second to and second base membranes overlap each other and also a portion of the second insert;

holding the second to membrane portion in place using one or more securing mechanisms;

holding the second bottom membrane portion in place using one or more suction devices;

forcing hot air over the overlapping areas of both the second top and second base membranes; and

pressing at least a portion of the overlapping membrane areas together.

14. A device for assembling roof fitments comprising

a stationary bolster having:

two substantially flat areas,

a curved area,

a plurality of suction devices, and

one or more securing mechanisms;

a ram located above said bolster and comprising:

a first die having one or more inserts and controlled by a main ram actuator assembly, and

a second die controlled by an auxiliary actuator assembly; and

a horizontally-retractable, interchangeable heating element between said bolster and said ram, said heating element having a plurality of hot air exhausts facing both the bolster and the ram.

15. The device of claim 14 further comprising:

a concave feature on the second die, said concave feature corresponding to the curved area of the bolster.

16. The device of claim 15 further comprising:

one or more suction devices on the first die of the ram.

17. The device of claim 16 further comprising:

one or more locating pins on the first die of the ram.

18. The device of claim 16 wherein:

the main ram actuator assembly and auxiliary actuator assemblies are capable of separate actuations.

19. The device of claim 16 wherein:

one or more inserts of varying geometries may be substituted for one another out of the ram.

20. The device of claim 16 wherein:

the main ram actuator assembly and auxiliary actuator assemblies are capable of a substantially continuous actuation.
