Abstract
An apparatus for unloading blanks of paper, cardboard, plastic, etc. that are stacked as blocks on a pallet and that are subsequently supplied as blocks of blanks for further processing or temporary storage includes a slightly pivotable insertion tool as well as structural elements for moving those stacks or blocks of blanks, relative to their support, that are disposed on the pallet at the edge thereof. The individual blocks of blanks are successively lifted from their support via an insertion tool, with a pressure foot preventing an undesired shifting and a holding foot securing the position of the respective block of blanks on the insertion tool.
Claims13
An apparatus for unloading blanks that are stacked as blocks on a support on a pallet and that are subsequently supplied as blocks of blanks for further processing or temporary storage, said apparatus comprising:
- a three-dimensionally controlled pick-up head;
- an approximately horizontally oriented insertion tool pivotally mounted on said pick-up head for pivotal movement about a horizontal axis;
- pivot means for mounting said insertion tool to said pick-up head;
- a switch lever fixed to said insertion tool and pivotal therewith;
- stop means disposed on said switch lever for limiting pivotal movement of said insertion tool in a downward direction;
- a spring disposed between said pick-up head and said switch lever, said spring providing a spring force for biasing said switch lever toward said pick-up head;
- and
- switch means actuatable by movement of said switch lever so as to discontinue a downward movement of said pick-up head when said insertion tool has been pivoted about a prescribed angle against said spring force.
