Tube end processing system
First Claim
1. A system, for processing first and second ends of tubes, comprising:
- (a) a stationary support surface;
(b) a longitudinally extending stationary rail disposed on said support surface;
(c) at least three transversely extending crossbars mounted on said rail for supporting each said tube, wherein at least two of said crossbars are transversely slidable longitudinally along said rail for supporting a different length said tube;
(d) drive means for selectively and independently slidably moving said transversely slidable crossbars relative to each other on said rails;
(e) conveyor means disposed on at least one of said crossbars for transversely moving each said tube to predefined first-tube-end processing sites and to predefined second-tube-end processing sites;
(f) first-tube-end-processing machines each having a separate and stationary first machine base and a first-tube-end-processing module movably mounted on said first machine base, said first machine base disposed on said support surface in a first machine-base-access area, and having a portion disposed underneath one of said transversely slidable crossbars in a corresponding said first access area and said first module movably disposable proximate a corresponding said first processing site;
(g) second-tube-end-processing machines each having a second-tube-end-processing module disposed proximate a corresponding said second processing site; and
(h) controller means for activating said conveyor means to move said tubes to said first and second processing sites and for actuating said first machines to process said first ends of said tubes at said first processing sites and said second machines to process said second ends of said tubes at said second processing sites.

Abstract
A system for processing both ends of tubes, such a nuclear fuel rod cladding tubes. A conveyor, adjustable for different length tubing, supports and transversely moves the tubes to tube-end-processing sites. The conveyor is spaced up at the first-tube-end-processing sites to create first access areas. First-tube-end-processing machines have bases with a portion placed underneath the conveyor in these first access areas. The first machines have tube-end-processing modules movably mounted on the bases to accommodate different length tubing. The system also includes second-tube-end-processing machines having tube-end-process modules positioned at the second-tube-end-processing sites. The modules process the tube ends with such operations as deburring, attaching fittings for flush etching the tubes, etc. Preferably, the modules are aligned for the system to process both ends of a tube simultaneously.

7. A conveyor system comprising:
-
a first stationary support rail; a second stationary support rail disposed apart from and substantially parallel to said first stationary support rail; a plurality of walking beams slidably disposed on and generally perpendicular to said support rails with each having an inflatable bladder mounted on the top thereof for lifting, supporting and moving objects along the length of said walking beams; and drive means connected to said walking beams for selectively and independently sliding said walking beams relative to each other on said rails. - View Dependent Claims (8, 9, 10, 11)
