Abstract: A capsule marking device 1 includes: a conveying unit 2 that conveys a capsule C along a conveyance path 2a; a first imaging unit 30 that captures an image of the capsule C being conveyed, to obtain first imaging data; a marking unit 40 that performs marking on the capsule C being conveyed; and a control unit that sets a marking region on the capsule C on the basis of the first imaging data, and forms a marking pattern in the marking region by controlling the operation of the marking unit 40. The capsule marking device 1 further includes a separating unit 60 that selectively separates the capsule C being conveyed from the conveyance path 2a, and the control unit controls the operation of the separating unit 60 to separate the capsule C having a seam with a size equal to or larger than a predetermined reference size in the marking region in the first imaging data without forming a marking pattern.

Abstract: A marking inspection device 100 for transparent edible objects includes: a conveying unit 2 that conveys, along a linear conveyance path 2a, a transparent edible object C on which a marking pattern has been formed; an inspecting imaging unit 30 that captures an image of the transparent edible object C being conveyed on the conveyance path 2a, and obtains inspecting imaging data; and a control unit that determines quality of the marking pattern, on the basis of the inspecting imaging data 30. In the marking inspection device 100, the inspecting imaging unit 30 includes: a camera 31 disposed so that the imaging direction is orthogonal to the conveyance path 2a; a reflective illuminating unit 32 disposed on a same side of the conveyance path 2a as the camera 31; and a transmissive illuminating unit 33 disposed on an opposite side of the conveyance path 2a from the camera 31.

Abstract: 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.

Abstract: An appearance inspection device, which inspects an appearance of test objects, includes a first and second conveying means 21 and 22a conveying the test objects, a back/front reversal means 23 turning over the front and back surfaces of the test objects being conveyed by the first conveying means 21 and supplying the test objects to the second conveying means 22a, and a plurality of image-pickup means 30b and 30c capturing images of each test object from upper oblique directions while the test objects are conveyed by the first and second conveying means 21 and 22a. 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 means 30b and 30c. This appearance inspection device makes it possible to reliably and readily inspect an entire appearance of the test objects.

Abstract: A vibrating feeder provided with a feeder ball 14a having a circular bottom wall and a conveyance path formed along the periphery of the bottom wall 141a; a feeder body 16a supporting the feeder ball 14a so as to apply torsional vibration and conveying substance supplied on the bottom wall 141a along 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 body 18a supporting member supporting the feeder body 16a on 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.
