摘要:
Device to load a sintering boat with nuclear fuel pellets, comprising a loading chute (2) delimiting a travel pathway (4) for the pellets, the loading chute comprising an upper end (8) intended to receive pellets and a lower end (12) intended to lie close to a sintering boat, said loading chute (2) comprising gates (18, 20, 22) forming an obstacle in the pathway of the pellets so as to fractionate said pathway, said gates (18, 20, 22) able to be actuated alternately, and the lower end (12) of the loading chute being movable so that it can be drawn close to and away from a bottom part of the sintering boat.A further subject-matter of the present invention is a method to load a sintering boat with nuclear fuel pellets, using a device according to the present invention.
摘要:
A chute that minimizes segregation during the delivery of bulk material via gravity from a higher location to a lower location, has a plurality of surfaces arranged vertically, one substantially below the next, and directed such that some or all of the adjacent surfaces cause the bulk material transiting the chute to frequently stop its forward motion momentarily, and then change direction or switch back. The directing surfaces may be flat, curved, conical, or partially conical in shape, with a combination of truncated cones and complete cones, or all truncated cones. An optional second set of truncated cone segments is introduced on the top of one or more of the converging cones in order to contain any overflow due to surges of material. A set of auxiliary outboard cones associated with respective converging cones is designed to reduce the freefall distance when the converging cones overflow by design.

A conveying apparatus includes a conveying assembly and a vertical funnel assembly mounted at a discharge end of the conveying assembly for guiding the discharge of bulk material. The funnel assembly includes a vertical row of frames slidably disposed on a pair of vertical wires. Adjacent frames are connected by flexible connecting elements. Each frame releasably carries a funnel element for conducting the bulk material so that a funnel element can be replaced without having to dismantle all of the funnel elements. Each funnel element includes a safety release connection enabling the funnel assembly to collapse under excessive loads, thereby protecting the conveyor from damage.

An automated order picking system assembled from known, available components and that includes a manager computer to receive orders for goods from a customer and to break the order down into requested full pallets of multiple ordered layers of goods; layers of goods ordered by the customer; compatible ordered layers of goods that can be combined into full pallets; and compatible cases of ordered goods that can be formed into layers and into full pallets of multiple layers of goods; and vertical cells for receiving, storing and delivering cases of the goods. The vertical cells comprise towers having mutually facing tower sections that receive goods delivered to feed conveyors by gantry robots having end effectors capable of handling the goods and the tower sections passing the goods back and forth as the goods are moved downwardly for placement on the discharge conveyor under the control of a programmable logic computer. The full pallets, full layers and cases of goods are conveyed to a palletizer to be organized into the requested orders.

The objects (6) fall into a well (10) where their fall is slowed down by slanted blades (13) covered by a damping layer and situated in front of a counter-wall (14) from which they are separated by a gap (16). The counter-wall (14) is elastic so as to make the objects falling onto it rebound towards the lower blade. An outgoing track of the well (26) having a round shape is covered with a damping layer which absorbs the free fall energy at the outlet of the device. The invention can be applied to the continuous bulk carrying of fragile objects, such as pellets.

A serpentine-type merchandise storing and dispensing column used for an automatic vending machine has a pair of opposing, generally vertically disposed wave-formed walls forming a serpentine merchandise storing space therebetween. Each wall includes a plurality of arcuate boards pivotally coupled to a frame and are disposed generally vertically in succession. The arcuate boards of one wall are disposed in a staggered arrangement with respect to the levels of the arcuate boards of the opposing wall. Each arcuate board is urged by a tension-spring so as to pivotally swing into the serpentine merchandise storing space. Thus, the board cushions descending merchandise in the serpentine merchandise storing space. Each arcuate board has a plurality of vibration absorbing slots and a plurality of beads between, and in parallel with, the slots.

An apparatus for lowering particulate commodities includes a vertically disposed ladder extending from the upper end of the storage facility to the lower end of the storage facility. The ladder is formed of flexible planar sheets bent upon themselves to define substantially U-shaped chute member formed into a zigzag patttern such that the particulate commodities flow downward through the chute members passing from one chute member to the next chute member. The chute members are connected such that an opening is formed at the upper end of each chute member so that the commodities may exit the ladder once the level of the commodity within the storage facility has reached the upper end of a particular chute member.
摘要:
A feed pipe for conveying sticky bulk material from a bunker outlet vertically downward to a conveyor apparatus wherein the feed pipe is comprised of a plurality of truncated conical sections tapering downwards, the axial length and the diameter of the tubular sections being dimensioned such that arching of the bulk material is avoided.

A workpiece having an enlarged head and a stem extending therefrom is conveyed in a gravity chute while supported vertically in a ring-shaped pallet with the head supported on the top side of the pallet and the stem extending downwardly through the pallet. The pallet and workpiece are then directed through a downwardly curved orienting chute and come to rest on stop surfaces wherein the workpiece is inclined downwardly, its head foremost, and the axis of the pallet is horizontal. In this position the workpiece is centered with respect to the aperture in the pallet so that the workpiece slides downwardly out of the pallet through an unloading chute. At the lower end of the unloading chute the workpiece falls through a contoured aperture into a downwardly inclined delivery chute which extends in the direction opposite to the unloading chute.
