Abstract

In a conveying apparatus for castings in a cleaning device, there are tooth-type casting holders which rotate about a horizontal or slightly inclined axis and comprise two gripping parts of which the upper part serves as a tension member for tensioning the casting piece, while the lower stationary gripping part is comprised of two or more supports for the casting that promote the cleaning operation by means of a revolving movement. The supports are positioned at an angle to the axis of rotation and are spaced by substantially equal distances at both sides. These supports hold the casting in a corresponding angular position relative to the axis of rotation. The upper gripping part can comprise one or more pendulously supported beams which, in the tensioning position, transmit tensioning or securing forces to the casting. In this respect, the tooth-type casting holder performs not only a transportation and rotational movement, but also can transmit to the casting a vibratory movement by means of a roller of a vibrator. The tooth-type casting holder includes a bearing ring rotatably symmetric about the axis of rotation and by means of which the rollers of the vibrator are rotated during the rotational movement.
