Abstract
Abstract A method and an apparatus for stacking and destacking cylindrical as well as bulgy barrels which allow barrels to be stacked in several rows one on top of the other and to remove the rows of barrels one row after the other again. The apparatus includes a support frame with a storage bay for receiving the barrels. The storage bay includes a bottom feed and discharge opening through which several barrels which have been aligned in a row on a conveyor may be introduced into the bay. Means are provided for feeding the barrels to the feed and discharge opening, for aligning the barrels in a predetermined position, for lifting the barrels into the storage bay and for retaining the barrels within the bay.

A method of stacking and destacking barrels, said method characterized in that the barrels are grouped into several rows, the individual rows of barrels are displaced by a distance corresponding to half a barrel diameter towards the one side or the other side, then the rows of barrels are lifted into the bottom opening of a storage bay, at the same time lifting the lowermost row of barrels which is supported by holding members provided in the zone of the feed opening of the storage bay, together with the rows of barrels arranged on top of said lowermost row of barrels, and keeping the lowermost row of barrels in the lifted position by means of said holding members, and that for destacking said barrels, said holding members are released from engagement with the barrels of said lowermost row of barrels and said lowermost row of barrels together with the rows of barrels supported on top of said lowermost row of barrels are lowered by a distance corresponding to the height of one row of barrels and said lowermost row of barrels is led off while, at the same time, the next now lowermost row of barrels is engaged by said holding members.
