Abstract

A packing apparatus used for filling or/and emptying bottle cases or the like. The packing apparatus comprises an extension arm, which is adapted to have attached thereto a gripping head and which is articulated on two articulation points with the aid of steering rods defining a steering rod system which is adapted to be moved after the fashion of the bars of a parallelogram, said extension arm being adapted to be moved in an essentially horizontal direction via a cam disk. The steering system also comprises a bipartite steering rod whose parts are adapted to be pivoted relative to each other. By pivoting the two parts of the steering rod relative to each other with the aid of a second cam disk and by changing thus the effective length of the steering rod defined by these two parts, an essentially vertical motion can be superimposed on the horizontal motion of the extension arm, to provide an appropriate path for the gripping head.

Dependent claims

Apparatus for crating or uncrating a group of bottles with respect to cases adapted to hold a group of the bottles comprising a frame, an extension arm extending in a generally horizontal direction, a gripping head comprising a plurality of gripping elements for simultaneously gripping a group of bottles suspended from a free end of said extension arm, a first steering rod pivotally mounted at one end about a horizontal axis to the frame and pivotally connected at its opposite end at a first pivot point to the extension arm remote from its free end, a first rotary cam means for pivoting said first steering rod about its axis and cause essentially horizontal motion of said extension arm and gripping head, a second steering rod comprising two steering members pivotally connected at one end thereof relative to each other, with the opposite end of a second one of said members being pivotally connected to the extension arm at a second pivot point and the opposite end of a first one of said members being pivotally mounted about a horizontal axis to the frame and second rotary cam means for pivoting said first steering member of said second steering rod about its axis as said first steering rod is being pivoted about its axis for thereby simultaneously causing essentially vertical motion of said second steering member and of said extension arm and gripping head.
