Vario-tip system

A packaging device for packaging injection-molded plastic parts in final package units, the injection-molded plastic parts being pipette tips or medical reaction vessels, the packaging device being configured to implement a packaging method and to interact with an injection molding device disposed adjacent to the packaging device and configured to produce pipette tips or medical reaction vessels, the packaging device comprising:

• at least one removing gripper configured and controlled by control means to simultaneously remove multiple shots of a number K of injection-molded plastic parts from the number K of respective cavities of an injection molding device, the number K of the respective cavities being distributed evenly over a number C of clusters,
• subgroup forming means, comprising the at least one removing gripper, configured and controlled by control means to evenly distribute the number K of the injection-molded plastic parts in a cavity-pure manner over a number U of cavity-pure subgroups in a first storing plane until each subgroup contains a number L of injection-molded plastic parts, the number L of the injection-molded plastic parts of one subgroup corresponding to a maximum number A of injection-molded plastic parts that can be contained in one final package unit or to an integer divisor of A,
• means configured to fill up the final package units in a cavity-pure and/or cavity-sorted manner until the final package units each contain the number A injection-molded plastic parts,
• wherein the packaging device has a lateral inspection device comprising at least one digital camera, the lateral inspection device being configured and controlled to subject the injection-molded plastic parts of the subgroups to an optical lateral inspection before the final packages are filled up,
• wherein the lateral inspection device is configured to detect defective injection-molded plastic parts which are to be sorted out, and
• wherein the packaging device has first sub-subgroup grippers for dividing each of the subgroups into a number S sub-subgroups of injection-molded plastic parts disposed one behind the other linearly, and transfer means for transferring the S sub-subgroups one after the other, the transfer means being configured to transport the S sub-subgroups through the lateral inspection device one after the other for lateral inspection, and
• wherein the packaging device has second sub-subgroup grippers configured and controlled by control means in such a manner that the S sub-subgroups are arranged in inspected cavity-pure subgroups in a second storing plane after having passed through the lateral inspection device, the composition of the cavity-pure subgroups corresponding to the composition of the subgroups of the first storing plane when no individual injection-molded plastic parts have been sorted out because of defects detected, and wherein the second storing plane is formed either directly by the final package units or by a stationary or adjustable horizontal intermediate storage and the inspected subgroups are movable from the intermediate storage into the final package units by gripper means.
