Abstract: The lifting and transportation of sensitive articles incapable of bearing a mechanical load, without manual involvement, presents special difficulties in packaging technology. This applies, above all, to tray packs in which articles are arranged standing on a bottom part (11) of small height, without any additional anchoring. For grasping and lifting articles of this type, there is provided a raisable and lowerable suction box (15) which, with suitable dimensions, is placed over the article in the manner of a bell. By the generation of a vacuum within the suction box (15), the article (tray pack 10) is held carefully and can be lifted by means of the suction box (15). Side walls (22) of the suction box (15) are arranged pivotably, to make it easier to place the suction box (15) onto the article.

The plate is connected with a vacuum vessel through a closable vacuum opening on the one hand, and on the other hand, through a calibrated opening that serves to effect a controlled leakage to keep the vacuum within the vacuum vessel at a pre-defined maximum value.

Abstract: In an apparatus for setting down cross-wound bobbins into a transport container, preferably onto a pallet, cross-wound bobbins are received at a transfer position with a programmable apparatus, such as a programmable palletizing apparatus. A plurality of the cross-wound bobbins are simultaneously delivered in succession in a plurality of increments from the transfer position onto a pallet or into a transport container at a drop-off location with the programmable apparatus.

Abstract: An improved palletizer is provided for receiving successive groups of articles in a pattern forming area and transferring the groups in succession to a stacking area on a pallet. A servocontrolled sweep system transfers article groups from the pattern formings to the stacking area for stacking one group on top of the other as the pallet is indexed downward by a hoist system after each successive group, and a carriage system interleaves separator sheets between successive groups. A programmable logic controller controls the servocontrolled sweep system in accordance with a velocity characteristic designed to increase machine speed and efficiency.

Abstract: A device for slowing cut sheets in seriatum flow by nipping the trailing edge of the sheets as they leave a high-speed conveyor system is provided whereby the sheets pass to a stacking pile at a slow speed. The nipping device is provided in several embodiments including a brush carrying roll, an oscillating roll on a lever arm and an air jet. Ream removal apparatus are also provided to remove reams of paper from the bottom of the stacking pile.

Abstract: Individual air permeably sheetlike structures are efficiently lifted from a pile by a vacuum lifter and deposited again at a processing station, the pile including as an alternate interlayer a sheet of air impermeable material.

Abstract: In the loading of pallets (10) with cartons (11) arranged in layers (carton layer 14), intermediate layers (24) consisting of paper or the like frequently have to be introduced between the carton layers (14). The pallets (10) are loaded by a palletizer (13) which is known for these purposes and which has a pivotable and multiply bendable cantilever arm (19). The intermediate layers (24) are laid onto the carton layers (14) by this cantilever arm (19) with a suction holder (23). At the same time, portions of a continuous web of material (25) running off from a reel (26) are drawn onto the completed carton layer (14) and then severed to the correct size from the web of material (25).

Abstract: An automatic assembly system for assembly of transformer laminated cores of the type having three parallel legs and two yokes. The laminations are stacked in a simple or complex configuration on a movable support frame on tracks, which receives the core laminations at a lamination loading station from four movable platforms on independent tracks. The platforms are grouped circumferentially about the support frame at four lamination feed positions while it is at the lamination loading station and have thereon stacked corresponding core laminations that are to be stacked on the support frame in a proper sequence and position order for forming a transformer laminated core. The system has four travelling gantry cranes that are on independent tracks and are each provided with a pick-up frame having suction cups arranged thereon for lifting the laminations individually from corresponding platforms at the four lamination feed positions and depositing them on the support frame in a properly stacked relationship.

Abstract: A sheet transfer device and method are disclosed for transferring sheets from a sheet stack to a utilization area such as a can pallet. A base unit causes pivoting of a beam about a moveable pivot point so that a sheet picked up from the sheet stack is moved upwardly for a substantial distance and then pivoted to a point above a can pallet, after which the sheet is moved downwardly and deposited on the upwardly extending tops of a horizontal layer of cans on the can pallet. Suction is supplied through a plurality of cups brought into engagement with the top sheet of a sheet stack to lift the top sheet from the stack, with the suction being terminated when the sheet is deposited on the can pallet to thereby release the sheet.
