Abstract:
A method and apparatus for grouping of objects such as books or the like to stacking layers for loading onto pallets wherein stacks of equal height are formed from the individual objects, and are conveyed sequentially for forming a stacking row, the length of which corresponds to the transverse dimension of a pallet; at least one of the stacks in a given stacking row is rotated by 90.degree. with respect to the other stacks in the given stacking row, and a gap is produced between the thusly rotated stack and the remainder of the stacks in the stacking row, the stacking row then being pushed onto an intermediate storage table, with subsequently arriving similarly oriented stacking rows being pushed onto the first stacking row to form a tier, and subsequent tiers similarly formed but with differently oriented stacks to provide a staggered or overlapping bond and thus a stable pallet stack.
Abstract:
A method of sawing and stacking sheets of fiberboard and similar material includes placing a first sheet to form a support. A plurality of second sheets are now divided into smaller sheets and are stacked on the first sheet without altering their positions in relation to each other.
Abstract:
In a system for cubing rectangular units such as block or brick, there is provided a system for reorienting selected ones of the units to formulate layers in the cube to provide maximum stabilization of the units in the cube. The apparatus includes an orientation station comprising a plurality of planar tables, selected ones of which are movable laterally in a horizontal plane, rotated to reorient units thereon, and return to their original position for offloading of the reoriented blocks.
Abstract:
A wheel-supported palletizer frame structure has an empty-pallet magazine containing an empty pallet stack from the bottom of which empty pallets are delivered one by one to a hydraulic scissors pallet elevator while the rearward ends of the pallets remaining in the stack are temporarily lifted. The pallet elevator has a table which is raised and then lowered step-by-step by a hydraulic scissors mechanism from successive elevated positions wherein the platform or each tier of bags thereon is lowered in timed relationship with a rotary and reciprocable open-ended bag positioner. Filled bags are fed one-by-one to either of the opposite ends of the bag positioner from a horizontal bag conveyor aligned with the bottom of the bag positioner and coupled thereto for travel back and forth therewith. The bag positioner is rotatable between either of two longitudinal positions aligned with the conveyor and movable into any one of a plurality of lateral positions disposed transverse to said bag conveyor. The bag positioner is also movable laterally of the bag conveyor to position the bags dropped therefrom onto different longitudinal positions parallel to the bag conveyor. The bag positioner is also mounted for motion transverse to the direction of motion of the bag conveyor to deposit the bags in different lateral positions perpendicular to the bag conveyor. The open-ended bag positioner enables individual bags to be swung horizontally to positions 90.degree. and 270.degree. apart in order to position the sewed end of each bag on the inside of each tier of the stack of bags on the pallet. The four-wheeled mount of the entire machine enables it to be moved bodily to any desired position upon the floor of the warehouse or other palletizing building.
Abstract:
A charge of logs for storage or transfer to a wood grinder is moved from an open top hopper of a loading rack by forklift vehicle while the adjacent hopper of the loading rack is being filled with logs by a conveyor positioned above the loading rack. The loading rack incorporating the open top hoppers is horizontally shiftable so that when one of the hoppers is filled with a charge of logs, the rack is shifted to position an empty hopper beneath the conveyor to receive a subsequent charge of logs. During loading of a charge of logs in the empty hopper a forklift vehicle unloads the log charge from the filled hopper and transfers the charge to a charging rack above a magazine of a wood grinder or to a storage rack.
