Abstract

Abstract Batteries are moved along a first roller type conveyor to a leak testing station, above which is located an assembly having a plurality of nozzles matable over battery cell inlets. A first set of alternate cells is supplied with air at a given pressure, and metering means notes pressure change. Thereupon, the remaining alternate cells receive the same treatment. If the cells do not leak, the battery advances from the testing station along the roller conveyor. If a leak is detected, a push bar connected to a cable system below the rollers ejects the battery transversely from the testing station along to a second conveyor, thereby isolating leaky batteries either for removal or further testing to locate more precisely the leak.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 162 words
In an automotive battery production system, apparatus for selectively isolating automotive batteries comprising: a. first and second conveyor means, each comprising a plurality of parallel rollers, at least a portion of the rollers being elongated rollers each of which extend at least substantially across both conveyor means in the vicinity of a battery processing position defined on said first conveyor means, whereby said elongated rollers constitute a portion of each of said conveyor means; b. continuous cable means between said first and second conveyor means disposed parallel to and underneath said elongated rollers; and c. a pusher disposed contiguous to said battery processing position mounted to slidably track along at least two of said elongated rollers upon motion of said cable means to slide a battery substantially axially along said elongated rollers to said second conveyor means, said rollers coacting with said pusher to substantially prevent movement of said pusher in a direction transverse with respect to the axis of said rollers.
Claim 2
Dependent Claim 162 words
In an automotive battery production system, apparatus for selectively isolating automotive batteries comprising: a. first and second conveyor means, each comprising a plurality of parallel rollers, at least a portion of the rollers being elongated rollers each of which extend at least substantially across both conveyor means in the vicinity of a battery processing position defined on said first conveyor means, whereby said elongated rollers constitute a portion of each of said conveyor means; b. continuous cable means between said first and second conveyor means disposed parallel to and underneath said elongated rollers; and c. a pusher disposed contiguous to said battery processing position mounted to slidably track along at least two of said elongated rollers upon motion of said cable means to slide a battery substantially axially along said elongated rollers to said second conveyor means, said rollers coacting with said pusher to substantially prevent movement of said pusher in a direction transverse with respect to the axis of said rollers.
Claim 3
Dependent Claim 21 words
Apparatus as described in claim 1 wherein said pusher extends between ones of said longer rollers to track between said rollers.
Claim 4
Dependent Claim 39 words
Apparatus as described in claim 1 further comprising: a. means for subjecting said batteries to a battery process at said battery processing position; and b. means for producing motion of said cable in response to results of said process.
Claim 5
Dependent Claim 91 words
Apparatus as described in claim 1 wherein said continuous cable means comprises a first cable loop over a first set of pulleys, said loop operable in response to said results of said processs; and a second cable loop over a second set of two pulleys and connected at at least one point to said first cable loop, said pusher being connected to said second cable loop; and wherein said means for producing motion of said cable comprises motor means operable to rotate at least one of said second set of pulleys.
