1. A workpiece carrier device for holding and moving workpieces having:
a workpiece carrier for receiving workpieces, which is mounted on a main frame so as to rotate about an axis,
a drive part, which can likewise rotate about the axis relative to the workpiece carrier, and
multiple workpiece holders, which are arranged on the workpiece carrier in a ring around the axis and are mounted on the workpiece carrier so as to rotate about holder axes which are spaced from the axis,
wherein the holder axes run in relation to the axis in such a way that the workpiece holders and/or the workpieces arranged in the workpiece holders form a conical crown arrangement and
wherein the drive part comprises a crank disk with link slots, wherein the link slots are designed as elongate oblong slots that are oriented radially to the axis, and which are arranged on the circumference and in each of which a drive portion of the workpiece holder runs, via which during operation the workpiece holders are set in a rotary motion,
wherein each of the workpiece holders is designed in a crank-like fashion and comprises a crank portion which runs between two coaxially extending end portions, one of which is rotatably mounted as a bearing end in a bearing point of the workpiece carrier and the other of which is rotationally arranged as a receiving end in a bearing opening of the workpiece carrier,
wherein the crank portion forms the drive portion that interacts with the link slots and that, during the drive of the crank disk, performs a reciprocating movement in these link slots and thereby exerts a rotary movement about the holder axes, and
wherein a support plate arrangement is provided, the support plate arrangement comprising guide slots fixed to the workpiece carrier, wherein a guide opening of the crank disc is located in each of the guide slots, and wherein said support plate arrangement is configured to stabilize the crank disc in a plane of movement.
