A test object carrying device for use in an appearance inspection device for checking the appearance of the test objects, which includes a back/front reversal unit for turning over the test objects being conveyed by the forward conveying means and supplying them to the returning unit; the back/front reversal means is provided with a first drum for rotating and conveying the test objects unit while holding the test objects on the peripheral surface thereof, and a second drum for rotating and conveying the test objects being conveyed by the first drum while holding the test objects on the peripheral surface thereof; wherein at least one of the first drum and the second drum is structured so that the test objects are transferred in parallel to the forward conveying unit and returning unit by rotating and conveying the test objects while holding them on the peripheral surface thereof.

Carrying device and appearance inspection device for test objects

An appearance inspection device, which inspects an appearance of test objects, includes a first and second conveying meansandconveying the test objects, a back/front reversal meansturning over the front and back surfaces of the test objects being conveyed by the first conveying meansand supplying the test objects to the second conveying means, and a plurality of image-pickup meansandcapturing images of each test object from upper oblique directions while the test objects are conveyed by the first and second conveying meansand. The appearance inspection device also includes a defect detection means detecting the presence of defects in the test objects based on image data captured by the image-pickup meansand. This appearance inspection device makes it possible to reliably and readily inspect an entire appearance of the test objects.

Appearance inspection device

A vibrating feeder provided with a feeder ballhaving a circular bottom wall and a conveyance path formed along the periphery of the bottom wall; a feeder bodysupporting the feeder ballso as to apply torsional vibration and conveying substance supplied on the bottom wallalong the conveyance path; and a main body supporting member for supporting the feeder body; the conveyance path comprising an ascending rail and descending rail disposed in the downstream of the ascending rail in the conveyance direction; the main bodysupporting member supporting the feeder bodyon a horizontal floor so that a torsion axis C, which becomes the center of the torsional vibration, is inclined relative to the vertical direction; the ascending rail and descending rail conveying the conveyed objects upwardly or downwardly relative to the horizontal direction while the feeder body being supported by the horizontal floor via the main body supporting member.
