Abstract
A weld wire recovery system recovers the spent weld wire pieces from steel can bodymakers. The weld wire recovery system comprises a modular collection station installed at each bodymaker. The modular collection stations are connected via headers to a single central collection station. Each modular collection station comprises an entry fitting into which the spent pieces of weld wire drop. A primary air intake is connected to each entry fitting. An exhauster at the central collection station draws transport air into the upstream end of the primary air intake and into the entry fitting at a volume and velocity sufficient to sweep the pieces downstream through the header to a separator. A dielectric flexible connector directs the pieces from the bodymaker to the entry fitting. The flexible connector can be removed from the entry fitting for sampling the condition of the pieces. The flexible connector cooperates with a breakaway joint between the modular collection station and the header to enable a modular collection station to be removed or installed without affecting the operation of other bodymakers or the rest of the recovery system.
