Abstract

The disclosure is directed to a new scrap kick-out conveyor for a continuous buttweld pipe mill installation. The pipe mill includes a scrap cut-off saw, located between the welding mill and the subsequent processing mills, and the kick-out conveyor is located downstream of the scrap saw. The conveyor includes stock advancing rolls, for supporting and advancing the pipe stock, and inboard and outboard guide rails for laterally confining the pipe. Means are provided for retracting selected portions of the outboard guide rail and for diverting selected portions of the inboard rail to lie across the pass line, such that the oncoming scrap section is diverted off of the conveyor. An inclined discharge apron is provided adjacent the outboard guide rail, leading to a scrap bin. The retractable portion of the outboard guide rail is arranged to retract downwardly, and is provided with an inclined upper surface to facilitate gravity discharge of the scrap sections.

Claims1

Dependent claims

A scrap kick-out conveyor for a continuous buttweld pipe mill installation provided with a scrap cut-off saw between the forming and welding mill and subsequent processing mills, which comprises

(a) stock advancing conveyor rolls located on the pass line downstream of the scrap saw,
(b) inboard and outboard lateral guide rails on opposite sides of the pass line for guiding and confining pipe stock supported on said conveyor rolls,
(c) means for retracting at least selected portions of the outboard guide rail,
(d) means for diverting at least selected portions of the inboard guide rail to lie at an angle across the pass line to divert oncoming cut scrap pipe sections off of the outboard side of the conveyor,
(e) means for receiving diverted scrap pipe sections for disposal, and
(f) an inclined apron provided adjacent the outboard guide rail,
(g) said selected portions of the outboard rail being downwardly retractable and having a downwardly inclined upper surface to facilitate gravity discharge of scrap pipe diverted from the pass line.
