  • Apparatus and process for inspecting sealed packages
    Patent number: 6105419
    Abstract: An apparatus for inspecting sealed packages of product includes a conveyor belt for receiving the packages. An inspection belt contacts the packages and moves away from the conveyor belt a particular distance depending on whether the packages are properly sealed. When engaged by a package with a good seal, the inspection belt is moved a first distance which causes an indicator carried thereon to send a signal which prevents removal of the good package from the conveyor belt. However, when a leaky bag contacts the inspection belt, the inspection belt is moved a second distance which is insufficient to cause the indicator to send a signal. Consequently, the improperly sealed package is removed from the conveyor belt. The inspection belt may be mounted for linear or pivotal movement upon being contacted by the packages carried by the conveyor belt.
