A package -culling conveyor system and a method for culling flat packages from a bulk flow of flat and non-flat packages. The conveyor system includes a tilted conveyor belt (24) conveying flat packages while non-flat packages tumble off its lower side. A high - friction conveying surface or a raised barrier along the length of the conveying surface of the tilted conveyor belt (24) holds flat packages on the tilted belt. The separated packages are more fully culled in a conveyor comprising a roller conveyor belt (36) with belt rollers (38) rotated in a direction to push packages sidewise toward a culling element that extends along the belt's length. Culling elements include powered rollers (55) or vertical walls forming side guards. The culling elements block the non-flat packages from exiting off the side of the belt so that they are conveyed off the end of the belt separate from the flat packages.

Apparatus (1) for sorting used bricks (2). The apparatus (1) is adapted to remove mortar, debris and brick pieces from the used bricks, whereby cleaned bricks are provided. The apparatus comprises a transport unit (4) for transporting the used bricks 2 and at least one sorting unit (5) comprising sorting stations (6) for removing mortar and brick, and a cleaning unit (7) for removing the mortar adhering to the sorted used bricks (2). The transport unit (4) comprises a number of separated parallel tracks (9) adapted to transport the bricks 2 axis-parallel to the transport direction of the tracks (9), and in the tracks (9) at least one sorting station (6) is placed. The sorting station (6) is adapted to lead the used bricks (2) measuring at least a length X from one end to the other end of the brick (2), said length being parallel with the longitudinal axis of the bricks, said bricks passing the sorting unit (5).

The apparatus makes use of a pair of rotating combs (11-14), the discs of the second comb being interposed between the discs of the first comb and positioned at the top between fixed guide plates (17). The discs of the first comb intercept the streams of closed capsules, from which any covers not provided with shells have already been removed. The capsules are inserted by their shells between the discs of the first comb and remain suspended on said discs by their covers (C1). Only capsule shells and any crushed capsules fall through the discs of the first comb. The capsules conveyed by the first rotating comb arrive on the discs of the second comb, generally with their covers at the front. The second comb transfers the capsules to the longitudinal guide channels (107') of a short vibrating table (7'), which in the initial part of each channel is provided with a longitudinal aperture (19) which allows the capsule shell to pass through but holds the capsule covers, which in this way arrive in a vertical position at a discharge hole (20). Any capsules carrying two covers pass over said hole (20) and are discharged into the hopper for rejects.

Ein Verfahren zum Aufbereiten von kleinstückigem Material, bei dem aus einem Langteile enthaltenden Feststoffgemisch die Langteile durch Bürsten abgetrennt werden, ermöglicht eine hohe Rückgewinnungsrate wertvoller Gemischbestandteile. Zum Abtrennen der Langteile aus dem körnigen Anteil des Feststoffgemisches ist einem Förderer (3) zumindest eine, seiner Breite angepaßte Bürste (11, 11', 11'') zugeordnet.

The present invention is an apparatus for segregating desired parts of predetermined dimension from a jumbled flow of such parts and by-product runners. The apparatus includes structure (30) that defines a path for restricting the jumbled flow to a fixed-flow space along a flow length. The apparatus comprises a three-dimensional array of rotatable pickup fingers (44) substantially filling the fixed-flow space and extending therebyeond. The apparatus further includes a suitable device for continuously moving successive distal portions of the rotatable finger array out of and into the fixed-flow space. The rotatable fingers (44) are spaced apart by distances greater than the predetermined dimensions of the desired parts but less than the longest dimension of the runners, for capturing the runners while allowing the desired parts to pass through the pickup-finger array. The apparatus additionally comprises stationary fingers (76), positioned to intermesh with the rotatable finger array, for causing the desired parts to become separated from the by-product runners. The apparatus further includes additional structure so located and configured as to remove the runners from the rotating fingers (44) during rotation of the finger array and allow the thus-removed runners to be conveyed under the influence of gravity away from the apparatus.

Process and plant for sorting grain or seed material such as coffee beans. The main problem when sorting such materials, lies in the shape of the grains which is far from being round, resulting in the grains going through the meshes of a sieve also depending on their position relative to the sieve. During the first stage of the process disclosed, foreign materials are removed from the material to be sorted which is then sorted in a moving sieve (15, 16) preferably linear. The vibrating motion, in relation with barrier baffle, provides a spreading of the material on the surface of the sieve and forces the grain to move along the longitudinal axis thereof. Thus, the probability for the grains to traverse the meshes of the sieve by their smaller cross section is increased. The efficiency of the screening operation is thereby increased. The installation comprises on the top of sieve (15, 16) barrier baffles (21) transversal to the motion of the material, and preferably made of elastic material such as rigid rubber.
摘要:
Die Erfindung bezieht sich auf ein neues Verfahren und eine neue Vorrichtung zum Klassieren von Korngut oder ' Saatgut, wie Hülsenfrüchten, Kaffeebohnen o. ä. Das Hauptproblem bei der Klassierung solcher Güter liegt darin, daß die einzelnen Körner stark von der runden Form abweichen und je nach der momentanen Lage des Einzelkornes relativ zur unter ihm liegenden Sieböffnung dieses durch die Öffnung hindurchfallen kann oder nicht. Bei dem neuen Verfahren wird nun das Klassiergut in einer ersten Stufe von Fremdstoffen gereinigt und durch eine (vorzugsweise linear) bewegte Siebfläche (15, 16) klassiert. Durch die Vibrationsbewegung in Verbindung mit den Staustufen wird eine starke Umschichtung der Körner auf der Siebfläche erzielt und diesen eine Bewegung um die eigene Achse aufgezwungen. Hierdurch wird die Wahrscheinlichkeit eines Ausrichtens der Körner derart, daß sie über ihre kleinste Querschnittsfläche durch die Sieböffnungen durchfallen können, und dadurch auch die Ausbeute des Verfahrens verbessert. Bei der neuen Vorrichtung werden oberhalb des Siebes (15, 16) und quer zur Sieblängsrichtung Stauglieder (21), vorzugsweise aus elastischem, jedoch steifem Gummi, angeordnet.
