An appearance inspecting apparatus includes a parts feeder aligning rubber stoppers in tandem by torsionally vibrating a bowl having a spiral track formed therein, an air conveying portion conveying the rubber stoppers aligned in tandem by blowing compressed air thereto, first and second conveying tables conveying rubber stoppers by suction-holding a surface not to be inspected of the rubber stoppers, an inspecting portion inspecting a surface to be inspected of the rubber stoppers conveyed by the first and second conveying tables, and a selecting portion sorting out rubber stoppers that are determined to be defective, in accordance with the result of inspection by the inspecting portion. Objects to be inspected having a complicated shape are aligned preliminarily by using a vibration parts feeder, while highly accurate appearance inspection is conducted.

The invention claimed is: 1. A conveying apparatus, comprising: aligning means for aligning objects to be conveyed in tandem, by applying vibration to said objects to be conveyed; conveying means connected to said aligning means for conveying said objects, by blowing compressed air to said objects

The invention claimed is: 1. A conveying apparatus, comprising: aligning means for aligning objects to be conveyed in tandem, by applying vibration to said objects to be conveyed; conveying means connected to said aligning means for conveying said objects, by blowing compressed air to said objects to be conveyed aligned in tandem; and feeding means connected to said aligning means and said conveying means, for feeding said objects to be conveyed to said conveying means, by applying another vibration in a traveling direction of said objects to be conveyed, to said objects to be conveyed which are aligned in tandem. 2. The conveying apparatus according to claim 1, further comprising: retaining means connected to said feeding means and said conveying means for retaining a predetermined number of objects to be conveyed; and control means controlling said feeding means such that vibration of said feeding means is activated and stopped, based on the number of objects to be conveyed retained by said retaining means. 3. The conveying apparatus according to claim 1, wherein said aligning means includes means for aligning said objects to be conveyed in tandem in a predetermined orientation, by torsionally vibrating a bowl having a spiral track formed therein and by blowing compressed air to the objects to be conveyed on said track. 4. A conveying and inspecting apparatus, comprising: aligning means for aligning objects to be inspected in tandem, by applying vibration to said objects to be inspected; air conveying means connected to said aligning means for feeding said objects, by blowing compressed air to said objects to be inspected aligned in tandem; feeding means connected to said aligning means and said conveying means, for feeding said objects to be conveyed to said conveying means, by applying another vibration in a traveling direction of said objects to be conveyed, to said obiects to be conveyed which are aligned in tandem; conveying means connected to said air conveying means for conveying said objects to be inspected, by suction-holding a surface that is not to be inspected of said objects to be inspected; and inspection means operatively associated with the conveying means for inspecting the surface of the objects to be inspected. 5. The inspecting apparatus according to claim 4, wherein said object to be inspected has a columnar bottom portion, and a bottom surface of said column is said surface that is not to be inspected; and said inspecting and conveying means includes at least two projections provided to abut a side surface of said column in the traveling direction of said object to be inspected, and means for conveying said object by suction-holding said surface that is not to be inspected of said object to be inspected positioned by said projections. 6. The inspecting apparatus according to claim 4, further comprising: retaining means connected to said feeding means and said conveying means, for retaining a predetermined number of objects to be inspected; and control means for controlling said feeding means such that vibration of said feeding means is activated and stopped, based on the number of objects retained by said retaining means. 7. The inspecting apparatus according to claim 6, wherein said aligning means includes means for aligning said objects to be inspected in tandem in a predetermined orientation, by torsionally vibrating a bowl having a spiral track formed therein and by blowing compressed air to the objects to be conveyed on said track. 8. An apparatus for conveying and inspecting objects which comprises, a vibrating feeder which aligns objects in a uniform manner, a linear feeder connected to the vibrating feeder which applies another vibration in the traveling direction and air conveying means for conveying said objects by use of compressed air, a first conveying structure, substantially free of vibrational influences, adapted to a hold a first surface of the objects to be inspected while exposing a second surface thereof, an air conveying section connected to the linear feeder for conveying the objects to the first conveying structure, at least a second conveying structure adapted to receive the objects from the first conveying structure by holding the second surface while exposing the first surface thereof; and inspection devices operatively associated with the first and second conveying structures for inspecting the exposed surfaces of the objects on the respective conveying structures. 9. The apparatus of claim 8 wherein the objects are held to the first and second conveying structures by suction.
