The system comprises a main longitudinal surface, a conveyor for conveying the boards on the main surface, a width detector, and accumulating compartments located one after the other under the main surface, controllable traps located on the main surface providing access to the accumulating compartments, controllable gates for retaining or releasing the boards accumulated therein and a controller. The controller selectively distributes each of the boards into the accumulating compartments, and controls the gates of the accumulating compartments to release the boards accumulated therein when the sum of the widths of the boards accumulated is within the predetermined width range.

Abstract: An entire harvested ground fruit load is subjected to a first cleaning process on a cleaning table, which separates the smaller ground fruits, soil, stones, clods, vine stems, grasses and other debris from the larger ground fruits. The fall-through burden from the cleaning table is subsequently subjected to a second separation step using a pintle belt conveyor equipped with at least one spinning shear roller. Soil particles, stones, clods, vine stems, grasses and other debris fall between the pintles of the pintle belt conveyor and are discarded, while small ground fruits are moved by the spinning shear roller(s) and either recombined with the main ground fruit load or diverted to a separate path for storage. Operational speed of the pintle belt conveyor and rotational speed of the shear rollers can be adjusted to maximize the breakup of clods which impact the shear roller(s).

Abstract: An arrangement for separating cylindrical bodies, such as parisons for hollow bodies, which have at least one protuberance at a first end, has a pair of parallel guide elements between which the cylindrical bodies can be erected in that the cylindrical bodies hang on the guide elements in each case by way of the protuberance. The separation arrangement here has a height guide, wherein a spacing between the height guide and the cylindrical bodies, as seen in the conveying direction, decreases to a predetermined spacing in relation to the guide elements, as a result of which vertically projecting cylindrical bodies, as they are being conveyed in the conveying direction, are forced downwards by the height guide and wherein the height guide can be raised briefly by means of a lifting device in accordance with a triggering signal.

Abstract: A method for separating objects, such as stones, wherein each object is dropped through a predefined path, such as a drop tube. Then, for each object, the time when the object passes through a predefined point in the path is determined, as are selected characteristics, such as the color, of the object. The characteristics of the object are matched, if possible, to various criteria and, depending on the criteria to which the object is matched, a diverter gate is activated to divert the object from the predefined path to an appropriate collection bin.

Abstract: The present invention provides a unique mechanical method and device for sorting pieces (e.g. vegetables and fruits) of any desired size from unsorted and irregularly sized pieces. The device includes a pair of elongated cylindrical brushes, one of which is equipped with a spiraled furrow for propelling the unsorted pieces and another brush being a smooth surfaced bristled brush (an expelling brush) laterally positioned to the propelling brush so as to form a trough between the two brushes for longitudinally moving the pieces. The brushes are rotated in a common rotational direction. A contacting member, such as a pivotally mounted lever, traversing the trough and the smooth surfaced brush and laterally positioned above the trough at a predetermined distance will tangentially contact a piece of a desired sizing and guide the contacted piece along its interfacing surface.

Abstract: Slide fasteners are fed longitudinally one at a time along a path by at least one stream of air flowing along the path, and are then introduced into a clearance or gate which is narrow enough to prevent the passage of sliders so that when the slide fasteners have respective sliders, they are stopped at the gate, while when the slide fasteners have no sliders, they are allowed to pass through the gate and be further advanced by the stream of air. Thus the slide fasteners are automatically sorted or separated into two groups according to the presence of the sliders. Thereafter, the stream of air is interrupted whereupon the slide fasteners stopped at the gate are allowed to fall from the path into a container disposed below the gate. The slide fasteners thus fallen are disposed in the container in juxtaposition.

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.

Abstract: An apparatus (100) and method for sorting a batch (200) of electrical contact pieces (11, 11') into two groups. The apparatus is characterized by a tiltable frame (72) concentrically mounting an assembly of a rotatable circular table (74) in spaced relation to a platform (80) having a radial wall (82) of less diameter than the table (74) to define an opening (86) therebetween. The circular table (74) includes an annulus sized to receive contacts. A guide arrangement (46) including a pair of guide members (50, 52) allows the contacts to pass to the rotating annulus, the good contacts rolling between the opening and through central holes in the table and the bad contacts rotating around and being scraped from the annulus.

Abstract: A method of sorting rivets or similarly shaped articles, and apparatus therefor. Rivets are directed along a track to a notch where they are supported in a shank-down attitude against a rotating gauging wheel having a plurality of gauging holes conforming generally to the shape of the shank. The wheel is rotated so the gauging holes move upwardly with respect to the shanks while grooves in the periphery of the wheel guide the shanks toward the holes. Rivets with a uniform shank will settle into the holes so their heads are below the periphery, while rivets with bent, gouged, burred or oversized shanks will not settle fully into the holes. A rivet kicker timed to the rotation of the wheel ejects rivets not fully settled in the holes. Fully settled rivets are blown out of the gauging holes into a tube where they are conveyed by air towards a riveting machine.
