Apparatus and method for coating of elongate flimsy members
A coating apparatus and method for flimsy elongate members has at least one elongate funnel tube with an inlet, an outlet, and an intermediate portion, the inlet in a basin, a fluid circulating system suitable connecting the outlet to provide flow into the inlet. Each inlet receives an elongate flimsy component and utilizes the circulating fluid to pull the flimsy elongate member into the funnel tube whereby the coating of the flimsy elongate member is accomplished. The invention also includes the method for coating such a flimsy elongate member utilizing the coating apparatus.
1. A method of insertion of elongate flexible members into a coating tube, the elongate flexible members each having a first end, an opposite second end, and an intermediate portion, the method comprising:
providing fluid circulation to a coating tube, the coating tube having an inlet and a subordinate portion positioned below the inlet, the fluid circulation entering the inlet and flowing through the subordinate portion,
insertion of the second end of an elongate flexible member into the inlet, and providing sufficient fluid flow into the inlet to provide a bias for drawing the elongate flexible member into said coating tube.
2. The method of claim 1 further comprising suspending the elongate flimsy member by the first end connecting to drive system and controlling the draw of the elongate flexible member into the coating tube by controlling the drive system.
3. The method of claim 2 further comprising utilizing a control processor for controlling the drive system.
4. The method of claim 2 further comprising utilizing a control processor for controlling the fluid flow.
5. The method of claim 1 wherein the coating tube has an upwardly facing funnel at the inlet of said coating tube, and the method further comprising insertion of the second end of the flimsy member into said funnel.
6. The method of claim 1 further comprising forming a fluid vortex in the fluid circulation system before the elongate flimsy member is inserted therein.
7. The method of claim 1 further comprising providing fluid circulation to a plurality of coating tubes, the coating tubes each having an inlet and a subordinate portion positioned below the inlet, the fluid circulation entering each of the inlets and flowing through the subordinate portion.
8. A method of insertion of elongate flimsy members into coating tubes for coating said elongate flimsy members, the method comprising forming a fluid vortex at an inlet of said coating tubes and utilizing the vortex to draw the elongate flimsy member into said coating tube.
9. The method of claim 8 further comprising suspending the elongate flexible members above the inlet of said coating tubes and controlling the insertion of the elongate flimsy members into the inlet so as to optimize the insertion rate while preventing buckling of the elongate flimsy member.
10. The method of claim 9 further comprising forming a vortex at a plurality of inlets of a plurality of coating tubes and simultaneously inserting a plurality of elongate flimsy members into the plurality of inlets.
11. A method of insertion of a plurality of elongate flimsy members into a coating portion of process equipment, the method comprising creating a plurality of vortexes in a plurality of inlets configured as funnels, and simultaneously lowering the plurality of elongate flimsy members into the inlets.
12. The method of claim 11 further comprising controlling the lowering of the elongate flimsy members into the plurality of vortexes by a control processor to minimize buckling of the elongate flimsy members during the lowering.
13. A method of coating elongate flexible members, the elongate flexible members each having a first end, an opposite second end, and an intermediate portion, the method comprising:
providing a fluid circulation system having an inlet and a subordinate portion positioned below the inlet, portion,
circulating the coating fluid into the inlet and flowing through the subordinate portion thereby providing a bias for drawing the elongate flexible member into said inlet, and
insertion of the first end of the elongate flexible member into the inlet whereby the bias draws the first end into the intermediate portion.
14. The method of claim 13 further comprising forming a fluid vortex by the fluid circulation system, the vortex positioned at the inlet.
