Abstract
Abstract A package labeling and inspecting apparatus is disclosed which includes a first conveyor table having an apparatus mounted adjacent to the conveyor for applying labels to wrapped packages as they move along the first conveyor table. Provision is made for generating a control signal when a label fails to be applied to a package or is improperly applied. In response to the control signal, a reject conveyor is actuated to remove the defectively labeled package from the conveyor apparatus. Apparatus is also provided for inspecting the condition of the wrapping on the package to determine whether the package has been properly wrapped and, if necessary, to reject any defective packages from the conveying apparatus. The device according to the invention operates automatically to convey, label, inspect and assort wrapped packages.
