ABSTRACT:
A ware tester comprising a testing station and a conveyor for moving ware past the station, the station including a ware testing tool, and a drive for moving the tool toward and away from the conveyor to engage and disengage the ware and parallel to the conveyor while the tool is engaged with the ware. The drive includes first and second cranks spaced in the direction of conveyor movement and having first and second crank pins, respectively, with adjustable throws to determine the extent of tool travel in the conveyor direction. The tool is mounted on an orbital link for shifting movement toward and away from the conveyor, and the orbital link is supported by the first and second crank pins. The drive also includes a third crank having a third adjustable throw crank pin connected to the tool to drive the tool toward and away from the conveyor. A prime mover synchronously drives the cranks, and the apparatus may desirably comprise two such tools and two sets of three cranks synchronously driven from the same prime mover. The station may include a second driver synchronized to the prime mover to shift a portion of the conveyor to move ware first under one of the testing tools and then under the other.
