  • Patent number: 5537731
    Abstract: In a method for the automatic forming of packs of trimmed metal sheets for armatures of electrical machinery or the like, the pack (P') is formed by the controlled drop of a sheet stack (P) housed in a tubular magazine (1) open at the bottom. The pack is dropped against an underlying collection bottom (2) which is brought to a predefined distance from the lower end of the magazine (1). A tightening clamp (3,4) at the lower end of the magazine (1) blocks the stack (P) against a further gravity drop after its descent against the collection bottom (2). A subsequent first lowering of the bottom (2) to separate the pack (P') from the overlying stack, by virtue of a detachment device (22, 122), is followed by a detachment from the lower sheet (L') of the stack (P) of a possible sheet (L) which is mistakenly and temporarily held against the lower sheet (L') of the stack (P) but belongs to the overlying pack (P').

  • Patent number: 5380147
    Abstract: A device for lifting one or more flexible, flat parts such as stacked pap pasteboard, cardboard, plastic is disclosed. The device relies on the propensity of a bundle of such parts to flex up around its edge when compressed at a point away from that edge. In one embodiment, a compression device presses down on one bundle in a stack of several bundles of parts to be lifted and a second compression device presses down the underlying stack, thus opening up a gap between the upper bundle and lower stack. A lifting arm is driven into this gap, and a clamp presses down on the bundle above the lifting arm, grasping the bundle. Two retainers are extended down onto the lower stack to prevent the stack from moving as the bundle is lifted. Once contact between the lifted bundle and the remaining stack is broken, the retainers are withdrawn and the lifting device is maneuvered to a delivery position.

  • Patent number: 5160129
    Abstract: A sheet stacker, particularly for corrugated paperboard container blanks, has a downwardly movable elevator for supporting stacked sheets, firing rollers for feeding successive sheets in a path above the elevator, and a stop for stopping each successively fed sheet above the elevator and enabling each stopped sheet to drop onto a stack being formed. A flexible cam, preferably a resiliently flexible loop, is rotatably mounted above the elevator. The flexible cam is intermittently rotated to move the cam out of the path of a sheet being fed to allow a leading portion of this fed sheet to pass under the flexible cam, then to bring the cam into contact with a rear portion of the fed sheet to urge this rear portion towards the stack, and then to bring the flexible cam to rest in kissing contact with the fed sheet when resting on top of the stack being formed. Tolerance variations in the sheet thickness can be accommodated by flexing of the cam.

  • Patent number: 5042862
    Abstract: A gripping device for transporting a stack of flexible sheets includes two substantially horizontally spaced, parallel tines arranged for supporting the stack; and a counterelement supported above the tines in alignment with the spacing therebetween. The counterelement has a horizontal dimension in a direction parallel to the spacing between the two tines. A horizontal dimension is smaller than the spacing between the two tines. A device moves the counterelement substantially vertically towards or away from the tines. When an unstabilized stack of flexible sheets is received on the two tines and the counterelement is moved towards the two tines for gripping and stabilizing the stack therebetween, the counterelement and the two tines produce a curvilinear bending in the stack about a horizontal axis oriented parallel to the two tines when the counterelement is moved past an initial plane containing a top layer of the unstabilized stack.

  • Patent number: 5004401
    Abstract: This invention relates to a method of palletizing a variety of goods by layers and a device therefor. Goods are formed in a unit load by palletizing them layer by layer in the order of layer area dimensions from the bottom with due consideration to layer area dimensions of goods, dimensions of void spaces which are not occupied with goods, and the dimensional relation among goods so that the palletized goods will not collapse during transportation. A good may fall into the void on the layer below or project beyond the edge of a lower layer to disturb the equilibrium. The palletizing method according to this invention facilitates handling of easily collapsible cases such as corrugated fiberboard boxes in a unit load by pressing at least the two sides of one layer of goods, releasing the pressure and then pressing and holding the same again.

  • Patent number: 5002456
    Abstract: A stacking apparatus includes a stacking unit and a bundling unit arranged under the stacking unit. Located at the end of a prestacking space, as seen in the direction (F), is a limiting element which serves as a stop for the folds of the printing products. While the printing products fed, with their fold forward, in the feed direction (F) are being deposited on one another to form a prestack, they are supported approximately centrally by a supporting element in their edge region located opposite the fold. For depositing the prestack so formed into a rest table, supporting arms are pivoted into a position of rest and slide plates are moved out of the region of the stacking space. A residual bend of the printing products is thus preserved in their edge region, thereby improving the stability of the stack.

  • Patent number: 4953845
    Abstract: An arrangement for handling and guiding a bundle of sheets in and between stacking and binding stations in which the sheets are stacked and bound respectively. The arrangement includes an arm displaceable from a pressing position in which the arm engages an uppermost sheet in the bundle in the stacking station to form a pressed bundle, to a removed position in which the arm is disengaged from the uppermost sheet. The pressed bundle is moved through the stacking station and conveyed from the stacking station to the binding station while the arm is maintained in the pressing position to prevent sheet disarrangement during such passage. In the binding station, the arm is displaced to the removed position to form a released bundle which is compressed prior to binding in the binding station. A guard engages uppermost sheets in the bundle in the binding station during displacement of the arm to the removed position to prevent sheet disarrangement.
