US 2006/0185965 A1 · Conveyor for bar or pipe

Abstract

A conveyor system for transporting a work piece from a beginning point to an end point in a longitudinal direction with at least one process step applied in between to such work piece is provided according to the invention. The work piece is propelled in the longitudinal direction over a combination of grooved rollers and conveyor belt units in series. Grooved guide means with, e.g., V, U, or square shapes that are machined into the surface of the rollers prevent the work piece from moving laterally as it is transported in the longitudinal direction, and maintain precise spacing between a plurality of work piece strands undergoing simultaneous transport by the conveyor system. The conveyor belt unit located between the grooved rollers inhibits rotation of the work piece as it is transported in the longitudinal direction. This conveyor system is good for treating the entire exterior surface area of the work piece in a uniform manner, such as coating the surface of rebar, dowel bar, hollow tube, or pipe.

Dependent claims

A conveyor system for transporting a work piece from a beginning point to an end point in a longitudinal direction along an axis with a process step applied in between to the work piece, the system comprising:

(a) frame means located between the beginning point and the end point for supporting two horizontal rails spaced in parallel relation to the axis;
(b) roller means secured on top of the horizontal rails and transverse to the longitudinal axis for supporting the work piece and propelling it in between the beginning point and the end point, at least one of the roller means further comprising guide means located along its exterior surface for inhibiting the work piece from moving laterally as it is transported in the longitudinal direction;
(c) at least one conveyor belt means secured on top of the horizontal rails and transverse to the longitudinal axis, and being positioned in between two roller means, such flat conveyor belt means providing support for the work piece and propelling it in between the beginning point and the end point;
(d) drive means operatively connected to the roller means and conveyor belt means for rotating the roller means and conveyor belt means along their respective axes transverse to the longitudinal axis in a synchronized fashion;
(e) whereby the flat conveyor belt means inhibits rotation of the work piece around the longitudinal axis as it is transported between the beginning point and the end point.
