Abstract: A product detection system includes a first frame piece configured to be coupled to a first sealing jaw of a sealing machine, a second frame piece configured to be coupled to a second sealing jaw of the sealing machine, a first detector bar slidably coupled to the first frame piece, a second detector bar slidably coupled to the second frame piece, a first linear actuator coupled to the first detector bar to move the first detector bar, and a second linear actuator coupled to the second detector bar to move the second detector bar. An encoder is coupled to the second detector bar to detect movement of the second detector bar. The first and second linear actuators are configured to move the first and second detector bars toward one another.

Abstract: The present invention encompasses an interlocking carrier and a conveyor system composed of a plurality of the interlocking carriers. The interlocking carrier generally consists of a sleeve for the placement of cargo therein, at least one carrier guide and at least one guide support. The interlocking carrier may be a single molded article which is generally symmetrical about a midpoint axis. The interlocking carrier's symmetry allows for the formation of an endless chain of interlocking carriers based on a single mold. The design of the interlocking carrier also allows for the facilitated assembly of an endless chain of interlocking carriers without the necessity of tools, nuts and bolts. The conveyor system of the present invention is adaptable to a various assortment of packaging machines, and may replace an existing conveyor system or be an integrated component.
