Abstract
Apparatus for the head-to-tail stacking of objects or groups of objects, such as folded cardboard packaging boxes, which are substantially identical in terms of their shapes, their dimensions and the orientation with which they are presented to the apparatus. The apparatus includes an aligning and retaining device which is mounted on a shaft extending above and transversely with respect to a conveyor. The aligning and retaining device is arranged to remove and invert a first batch of objects at the same time as abutments position a second batch below the first batch. The first batch are then laid on the second batch to form a stack.
Claims6
Device for stacking objects head to tail such as groups of several stacked cartons having one thickness at one end and a greater thickness at the opposite end, comprising a stationary frame which supports a conveyor having belts spaced in the crosswise direction extending between a receiving zone and a delivery zone, a turning device having two arms each supported by a means of movement in rotation and translation, each means being placed between the receiving zone and delivery zone on both sides of the conveyor, the arms extending in a vertical plane parallel to the belts, two opposite vertical walls being fastened respectively to the arms, a crosswise edge extending between the two vertical walls in the vicinity of the crosswise shaft, two bottom edges attached respectively to the vertical side walls being at the level of the belts, when the turning device is placed at the receiving zone for loading this device with cartons, the arms being able to turn 180.degree. to put the turning device above the delivery zone, the bottom edges then being spaced fron this zone in the vertical direction and the cartons contained in the device being held above this zone by the effect of the side walls thrust toward one another by jacks.
