Abstract: The invention concerns itself with the automatic processing of metal sheets. These are placed onto pallets (6) in form of stacks (7) and are fed to a pallet storage (4) in form of a high multi-tier shelf coordinated to each production machine (1). Between the pallet storage (4) and the production machine is provided a transport device (9) movable vertically along the pallet storage, which accepts a pallet (6) with a sheet metal stack (7) or delivers an empty pallet (6). The transport device (9) contains a single-sheet feeder (11), for example in the shape of suction heads (20) which lift off the topmost sheet, place it on a sheet support table (23) and from there feed it to the production machine. So as to facilitate the disengagements of the sheets from one another, magnets (18) are so arranged that under their influence they spread the forward positions of the sheets from one another.

For this purpose a tube-conveying device is installed between a tube magazine (4) and a conveyor belt (2) extending alongside all of the pirn heads, containing means (51) to position the tube (50) into the conveying position and means (71, 6, 8) for the transfer of the tube (5) in its conveying position to the conveyor belt (2).
Abstract: A warehouse contains a fixed number of pallet-carrying primary modules (7) arranged in a rectangular block (8) and further arranged in side-by-side parallel longitudinal rows. A working row (A) provides an exposed front side (9) adjacent a worker's station (12, 13) with at least one storage row (B) disposed behind the working row and forming a single working aisle (18) if desired. A secondary module (S) is disposed externally of the block. The secondary module (S) is positioned at the upstream end of the working row and pushes the entire row downstream, causing the secondary module to join the block and the downstream primary module (45) to exit the block. The newly exited module is then moved transversely to the downstream end of a storage row, and the entire row pushed upstream, causing the exited module (45) to again join the block and the upstream primary module (46) in that row to exit the block.
Abstract: A method of stacking boxes, cases, cartons, crates or the like using a computer-controlled apparatus having a lifting grab fitted with two independently movable grippers between which a box to be lifted may be clamped. In a first step, the grab is positioned at a loading station, the grippers are relatively separated and then the grab is lowered over the next box to be stacked. One gripper is then moved to a datum position and the other gripper is moved towards said one gripper so as to clamp a box therebetween. The grab is raised and moved together with the clamped box to a stacking station whereat the grab is finely positioned to have the box correctly placed in the stack under assembly with said one gripper alongside a previously stacked box. The lifted box is released by moving said other gripper away from said one gripper and then the grab is raised clear of the stack without disturbing the placement of the last-lifted box.

Abstract: A paper arranging apparatus for unpiling a vertical stack of paper sheets disposed upon a paper feeding table and repiling the paper sheets into a vertical stack upon a paper piling table includes a vibrational transfer plate disposed within the vicinity of the upper region of the paper piling table, and a crossing plate pivotably mounted upon the upper end of the paper feeding table so as to be movable between a first inoperative elevated position, and a second lowered operative position which overlies the vibrational transfer plate. The crossing and vibrational transfer plates therefore bridge the lateral spacing defined between the paper feeding and paper piling tables in order to facilitate the paper transfer operation between the paper feeding and paper piling tables.
Abstract: Apparatus for converting a continuous stream of partially overlapping sheets of paper or the like into a succession of stacks has a table which is movable between a first position adjacent the discharge end of a conveyor for the stream of sheets and a second position adjacent a stack removing unit. When in first position, the table is lowered gradually at the rate at which the height of the growing stack on its top increases, and such table is mounted on a reciprocable carriage which further supports a platform adjacent to the table so that the platform can enter the gathering station and take over a growing stack while the fully grown stack on the table is advanced to the removing unit. The table and the platform are provided with conveyors so that a fully grown stack can be transferred from the table onto the removing unit and the conveyor on the platform can transfer a growing stack onto the table when the transfer of the fully grown stack onto the stack removing unit is completed.
Abstract: Two conveyors for stacks of paper sheets are coupled to each other for movement back and forth between a first position in which one of the conveyors receives one or more stacks and the other conveyor is relieved of the stack or stacks thereon, and a second position in which the one conveyor is relieved of the stack or stacks thereon and the other conveyor receives one or more stacks. In order to expel air from the stacks on the conveyors the foremost portions of the stacks are clamped by reciprocable rams to the respective conveyors and the thus clamped stacks are caused to move along stationary squeegees which bear against successive increments of the stacks behind the respective rams while the stacks, the respective rams and the respective conveyors move away from the stack-receiving positions.

Abstract: An automatic article stacking system wherein a plurality of articles to be stacked are arranged in layers prior to being stacked. The layers are advantageously arranged horizontally orthogonal to one another so as to enhance the stability of the stack. A measurement system is provided for determining whether any of the articles exceeds a predetermined size limit. In one embodiment which is arranged for stacking egg cartons, a determination that the egg carton exceeds the predetermined size limit signifies that the egg carton is open and, therefore, not in a form suitable for stacking. The open egg carton is conveyed under an elevator which accumulates the articles to be stacked, and to a discharge area. Thus, closed egg cartons are accumulated in layers and stacked. Successive layers of articles are stacked under prior stacked layers.
