Abstract

Abstract Containers, such as batteries, battery cases and the like, are moved along a first conveyor to a leak testing station, above which is located an assembly having means matable over the openings in the top of the container. The container is supplied with air at a given pressure, and metering means notes pressure change. If the container does not leak, the container advances from the testing station along the conveyor. If a leak is detected, a reject means ejects the container transversely from the testing station along a second conveyor, thereby isolating leaky containers for further processing.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 172 words
In a system for processing batteries, apparatus for longitudinally conveying a battery to at least one predetermined position comprising: a. a conveyor surface defined by a plurality of transverse rollers in a roller means, a first one of said rollers being pivotally connected about an adjacent second one of said rollers, b. a first actuating means for pivoting said first one of said rollers upwardly and above said adjacent second one of said rollers to a reference position, whereby longitudinal movement of a battery along said rollers is halted by said first one of said rollers, c. sensing means for selectively making a determination of the longitudinal dimension of said battery in said halted position, and d. a second actuating means coacting with said first actuating means and said sensing means for repositioning said first one of said rollers with respect to said second one of said rollers in response to said determination to thereby reposition said battery with respect to a preselected vertical axis along the longitudinal advancement of said battery.
Claim 2
Dependent Claim 172 words
In a system for processing batteries, apparatus for longitudinally conveying a battery to at least one predetermined position comprising: a. a conveyor surface defined by a plurality of transverse rollers in a roller means, a first one of said rollers being pivotally connected about an adjacent second one of said rollers, b. a first actuating means for pivoting said first one of said rollers upwardly and above said adjacent second one of said rollers to a reference position, whereby longitudinal movement of a battery along said rollers is halted by said first one of said rollers, c. sensing means for selectively making a determination of the longitudinal dimension of said battery in said halted position, and d. a second actuating means coacting with said first actuating means and said sensing means for repositioning said first one of said rollers with respect to said second one of said rollers in response to said determination to thereby reposition said battery with respect to a preselected vertical axis along the longitudinal advancement of said battery.
Claim 3
Dependent Claim 22 words
The invention of claim 1 wherein said means for repositioning comprises at least one cylinder actuatable in response to said sensing means.
Claim 4
Dependent Claim 47 words
The invention of claim 2 wherein said sensing means comprises a plurality of sensors fixedly mounted with respect to said reference position of said first one of said rollers, so that said battery actuates a predetermined number of said plurality of sensors depending upon its longitudinal dimension.
Claim 5
Dependent Claim 41 words
The invention of claim 3 wherein said means for pivoting said first one of said rollers comprises a hydraulic cylinder, a first end of which is pivotally connected through a yoke to said cylinder actuatable in response to said sensing means.
Claim 6
Dependent Claim 35 words
The invention of claim 4 wherein said means for repositioning further comprises a second cylinder actuatable in response to said sensing means, said second cylinder being pivotally connected at a first end to said yoke.
Claim 7
Dependent Claim 34 words
The invention of claim 5 wherein each of said cylinders actuatable in response to said sensing means is actuated in response to the interference of said battery with a respective one of said sensors.
