  • Patent number: 6444936
    Abstract: The invention relates to a device for sorting any desired pieces of products in dependence on criteria, and a method for operating the same. It is the object of the invention to provide a solution which permits a very fast at least three-channel fractionating of a product flow with a simultaneous mild treatment of products, at low expenditures for energy, and at a high wear resistance. The object is realized in that the products pass a first approaching zone, arrive in a second zone in which a separating element set into rotations by operation of a stepper-motor, including on its circumference with equidistantly spaced fingers, and which, in dependence on a respective control, transfers the products to be sorted into at least three further zones. A real-time image tracking system is provided which is adapted to capture the entire path of the products through the zones.

  • Patent number: 6209706
    Abstract: System for grouping and transferring articles from an upstream station to a downstream station. Articles are pushed onto a transfer station table and transferred as a row of articles to a downstream conveyor extending at right angles to the direction of the upstream conveyor. The transfer cycle is initiated by an article deflecting a whip switch, which actuates a pilot actuator. The pilot actuator sends air to a lifting ram, thus causing a rocker arm with a tooth to disengage from a timing wheel; the disengaged rocker arm opens an air valve, pressurizing a master cylinder. The master cylinder forces a ratchet arm to rotate a shaft having push-rod assemblies mounted on it. As the shaft rotates, push-rods jut up through slots in the transfer station table and push the row of articles onto a staging area, as new articles continue to move onto the transfer station. Flow of air to the lifting ram is interrupted as the article loses contact with the ship switch.

    Abstract: A diverter assembly, for diverting baggage from a main belt conveyor to an intersecting conveyor, includes a single row of diverter rollers pivotally mounted therein. The diverter rollers are continuously rotated with power mechanically derived from the main conveyor. The diverter assembly is mounted in a gap formed in the main conveyor and a lift mechanism raises and lowers the diverter rollers while a swivel mechanism simultaneously pivots the rollers so that the articles are diverted. The lift mechanism and swivel mechanism are synchronized, so that when the rollers are lowered they are oriented coaxially to take up very little horizontal space, and to decrease the size of the gap over which articles pass unsupported. When the diverter rollers are raised, however, the rollers are automatically pivoted, in part taking advantage of the greater room available, and the rollers divert articles from the main conveyor.

  • Patent number: 4541532
    Abstract: A machine for removing oversize solids such as large rocks from other material carried by a conveyor. This separator has a wheel with external spokes which radiate outward from its circumference and which is mounted above the conveyor at an angle to the centerline thereof. Requiring no external power source, the device is actuated by the solids to be separated with the energy for separation being derived from their motion on the conveyor. When solids larger than the desired size come into contact with the spokes of the wheel, part of the momentum of these objects is converted to rotational motion of the wheel. As it rotates, it has a tendency to deflect them laterally across the conveyor belt until they are pushed off the side of the conveyor.The wheels can be used singularly or in combination. Their use in combination is most desirable for wider belts. The wheels can be located at varying locations, angles, and heights above the belt. By experimental methods, the wheels are adjusted for optimum placement.

The system includes a horizontally oriented section for accumulating the items along the path and an apparatus for transporting the items therealong. The apparatus may be either a plurality of parallel, spaced-apart endless belts or a plurality of conveying sections interconnected together to form an endless carrier. Each section of the carrier may constitute itself a device for directly carrying one of the items. The invention provides an effective horizontal accumulator for items on a production or an assembly line operating at a relatively high speed. The accumulator operates on the FIFO principle so that, upon a malfunction of either upstream or downstream equipment, dated or otherwise sequentially marked items are stored in such a manner that the first item into the system is the first item to come out.

  • Patent number: 4353455
    Abstract: A potato handling apparatus includes a roller conveyor for receiving a continuous stream of irregularly sized potatoes with an aligning section at the upstream end of the conveyor which includes a series of two parallel flaps for turning and pushing the potatoes lengthwise into the valleys of the roller conveyor. To eliminate all but one potato from each valley, a singulating section is provided. The singulating section includes a rod longitudinally disposed adjacent one edge of the roller conveyor and a series of parallel overlapping sprocket-like discs which extend diagonally across the conveyor to a downstream position which is inwardly spaced from said edge of the conveyor. Each disc has cogs formed on the periphery thereof which perforate the valleys in succession to a depth which prevents the potatoes from being pinched between the discs and rollers.

  • Patent number: 4295560
    Abstract: A self-contained, moveable material handling apparatus is characterized by a chassis having a material conveyance surface mounted for rotation with respect to the central vertical axis thereof. A deck is also mounted for rotation with respect to the chassis, independently of the material conveyance surface. A loading boom, having a loading device on the end thereof, is mounted to the deck for rotation about the central vertical axis of the chassis. The boom is also pivotable about a horizontal axis and extendable and retractable along its own axis. The loading device and the boom cooperate to load material from the interior of a carrier onto the material conveyance surface. The surface rotates the material until it is deflected from the surface by a deflector conveyor onto a carry-off conveyor. The speed of the material conveyance is less than the speed of the deflector conveyor, which speed is less than the speed of the carry-off conveyor.

  • Patent number: 4256216
    Abstract: On a conveyor belt, an ejection mechanism ejects objects travelling thereon which do not fulfill predetermined requirements as detected by a detecting device. To speed up the return of the ejection mechanism to its home position, the ejection cycle is divided into several movements. First a striking element is propelled against the object to be ejected, then the striking mechanism pivots on a fixed point to bring the striking element out of the path of the objects. Next the striking element is retracted and the ejection mechanism pivots back to its original position. A locking device may be used to retain the ejection mechanism in the deflected position to ensure that the striking element is completely retracted before the ejection mechanism pivots back to the home position.

  • Patent number: 4087001
    Abstract: The form of a moving stack of cigarettes or other rod-like articles is improved (so that it more closely resembles a compact honeycomb formation) by subjecting the stack to transverse (periodic) displacement in a direction parallel to the lengths of the cigarettes. In order to displace the cigarettes without drag the surfaces which cause the displacement are moved at about the same velocity as the stack. In one arrangement these surfaces comprise bands alongside the stack and are displaced by reciprocating plungers. In another arrangement the bands are displaced by rotary cam surfaces.
