Benefits of technology
The present invention provides a packaging method for plastic injection moldings, specifically pipette tips and medical reaction vessels, which is improved in terms of cycle time and the correspondingly improved packaging apparatus. The method allows for easy identification of the plastic injection moldings from which an end packaging unit originates and the maximum number of plastic injection moldings that can be loaded in an end pack, while minimizing damage to the plastic injection moldings. The invention includes a buffer store to temporarily hold the K plastic injection moldings before being allocated to sub-groups or end packs. The use of a separate second set-down means, such as a gripper, makes it possible to further speed up the packaging process. The second set-down means can be a vacuum-type gripper or a mechanical gripper that picks up the plastic injection moldings, moves them to a set-down position, and offloads them at the set-down position.
Problems solved by technology
The disadvantage with the known method is that packaged plastic injection moldings are not associated in any way with certain cavities.
It is therefore no longer possible to ascertain clearly the cavity or cavities from which the plastic injection moldings of a certain end packaging unit originate.
Even in the case of just a single defective plastic injection molding in an end packaging unit, this results in the entire production run having to be recalled, rather than just the end packaging units filled with plastic injection moldings from a certain cavity or from certain cavities.
The disadvantage here is that the number A of plastic injection moldings which can be delivered in an end packaging unit has to correspond to the number K of cavities, or that the number A of plastic injection moldings which can be transferred in an end packaging unit has to be a whole-numbered multiple of the number K of cavities.
It is particularly disadvantageous that such an installation requires a vast amount of space for the hose arrangement and its cycle time is comparatively slow.

Embodiment Construction
[0041]Like elements and elements of like function are identified in the figures using like designations.
[0042]FIG. 1 shows, as part of an injection-molding installation, an injection-molding apparatus 1, comprising an injection mold 2, having K=16 cavities 3 for simultaneously producing K=16 plastic injection moldings 8 which are designed in the form of pipette tips or medical reaction vessels. The injection-molding apparatus 1 is assigned removal means 4 which are designed for example in the form of suction grippers, preferably with a number of suction elements corresponding to the number K of cavities, said removal means 4 being indicated merely in stylized form as an arrow and being part of a packaging apparatus 16. In the exemplary embodiment shown, the removal means 4 serve exclusively for removing the injection moldings 8 from the cavities 3, wherein the injection moldings 8 removed by the removal means 4 are transferred to set-down means 5 in the form of a (transfer) gripper,...

Abstract
The invention relates to a packaging method by which plastic injection moldings designed in the form of pipette tips or medical reaction vessels are packaged in end packaging units.The invention provides that the K injection moldings are, prior to being distributed over the U sub-groups in the set-down plane, set down in a buffer store (12) by way of a second set-down apparatus (5) which is separate from the first set-down apparatus (18), in particular by way of a hose arrangement or by way of a gripper.
Description
BACKGROUND OF THE INVENTION[0001]The invention relates to a packaging method by means of which injection moldings which are designed in the form of pipette tips or medical reaction vessels are packaged, and to a packaging apparatus by means of which plastic injection moldings which are designed in the form of pipette tips or medical reaction vessels are packaged. The invention also relates to an injection-molding installation having such a packaging apparatus, wherein the injection-molding installation is designed for the production of plastic injection moldings which are designed in the form of pipette tips or medical reaction vessels.[0002]In the case of known packaging methods by means of which plastic injection moldings which are designed in the form of pipette tips or medical reaction vessels, in particular for blood analysis, are packaged, K plastic injection moldings are removed simultaneously from K cavities of an injection-molding apparatus and are stored on an interim basi...
