摘要:
A workpiece handling system for inspection of workpieces having an elongated cylindrical segment with an enlarged feature such as a threaded fastener. A pair of rollers is inclined with respect to horizontal, and having cylindrical surfaces separated by a gap and rotated about parallel axes, with upwardly presented end surfaces. A drive arrangement rotates the rollers. A slide mechanism enables the rollers to be set at a first and second separation gaps. A workpiece transfer mechanism loads the workpiece onto the rollers, rotation of the rollers set at the first separation gap causes the workpieces to rotate. A sensor probe is positioned in close proximity to the workpiece head as the workpiece is rotated. A workpiece receiving system is provided for handling the workpieces when the rollers are set to the separation second gap, allowing the workpiece to fall under gravity between the rollers.

The invention relates to a sieve screen, which can be positioned in a utility machine-operated screen bucket or in a screening station maneuverable with its own actuator. A plurality of screening plates (3) are spaced from each other and establish a screening surface (2), which is provided with screening slots and on top of which can be placed the material to be screened. Rotatable shafts (4) are present below the screening surface (2). The shafts (4) feature blades (5), which protrude from the shafts and extend through the screening slots to above the screening surface (2). Fraction size is adapted to be changed without removing the shafts (4), by re-grouping the blades (5) and a necessary number of the screening plates (3). The blades (5) can be grouped in such a way on the shafts (4) that at least two blades (5) are set adjacent to each other and the adjacent blades are located within the same screening slot.

An assembly for separating selected defective objects from a group of objects used in tobacco industry, the group comprising regular objects having a form of substantially spherical external surface of a determined diameter and the remaining objects being defective objects, the assembly comprising a sieve element (105) having through channels (106) or holes and a generally flat blocking element (107) located under the sieve element, the blocking element having an upper surface /107B) and through holes (108), the sieve element and the blocking element being displaceable in a direction parallel and/or perpendicular with respect to each other at least between a first configuration and a second configuration. In the first configuration the channels or holes of the sieve element, and the holes of the blocking element enable the regular objects and selected defective objects to enter the upper parts of the channels and they enable the regular objects to fall through the lower parts of the channels and through the holes of the blocking element, while they hold said selected defective objects. In the second configuration the channels or holes of the sieve element and the holes of the blocking element enable said defective objects held in the first configuration to fall through the assembly. A method of separating selected defective objects from a group of objects used in tobacco industry using the assembly according to the invention.
摘要:
Es ist eine Aufgabe der Erfindung, neuartige Vorrichtungen und Verfahren zum Trennen von Material anzugeben, die insbesondere zur Grünguttrennung in mehrere Grüngutfraktionen geeignet sein sollen. Eine erfindungsgemäße Vorrichtung (10) zum Trennen von Material (30) in mehrere Materialfraktionen (34, 38, 42) umfasst ein Scheibensieb (12) mit einer Transportrichtung (T) für darauf aufgebrachtes Material (30), die von einem Scheibensiebanfang (14) zu einem Scheibensiebende (16) verläuft, zum Bereitstellen einer ersten Fraktion (34) des aufgebrachten Materials als Siebfraktion unterhalb des Scheibensiebes (12) und einer zweiten Fraktion (38) des aufgebrachten Materials als Überkornfraktion am Scheibensiebende (16), wobei durch wenigstens eine Modifikation der Scheibensiebkonstruktion eine verbesserte Trennungsgenauigkeit bzw. vereinfachte Anpassbarkeit der Trenncharakteristik an die Beschaffenheit und Zusammensetzung des zu trennenden Materials (30) erzielt wird. Ein bevorzugtes Anwendungsgebiet der Erfindung ist die Trennung von Grüngut (30) im Rahmen der Bereitstellung und/oder Aufbereitung von Kompostiergut.

The invention relates to a device for separating granular material, especially a light grain selector for cereal crops or similar, comprising a sieve cage with at least two sieve layers that are provided with perforated plates. The sieve layers can be penetrated by air from below. The sieve cage is equipped with at least one oscillating drive unit while each sieve layer (2 to 5) encompasses a final separation zone.

Bei einer Vorrichtung zum Sortieren von Objekten (10) unterschiedlicher Grösse nach ihrer Grösse, insbesondere von Früchten und Gemüse, umfasst die Vorrichtung eine Zuführungsvorrichtung (20), eine Sortiervorrichtung (1) und eine Auffangvorrichtung (30) für die Objekte. Die Sortiervorrichtung (1) umfasst mindestens ein Sortierelement (7) mit einer einstellbaren Durchtrittsöffnung.
摘要:
La présente invention concerne un dispositif de calibrage (1) dimensionnel d'objets (2) de forme sensiblement sphérique ou ovoïde tels que des fruits ou légumes comprenant : - une série de couples (3i, i=1 à n) de rouleaux parallèles entre eux entraînés en translation dans une direction longitudinale (XX'), - chaque couple (3i) comprenant un premier rouleau bi conique (4i), et un second rouleau cylindrique (5i), et liés entre eux à leurs extrémités par des bielles (6) aptes à être articulées en rotation par rapport à l'axe dudit premier rouleau, l'espace vide entre lesdits premier et deuxième rouleaux respectifs de 2 couples successifs définit une succession de compartiments (7) dans la direction transversale axiale (YY'). Quand desdits objets sont déposés entre et au dessus deux couples de rouleaux successifs (3i,3i+1) les objets d'un calibre inférieur ou égal à un calibre donné sont récupérés en dessous desdits compartiments (7). Et l'augmentation de l'inclinaison desdites bielles (6) permet de récupérer des objets de calibres croissants au fur et à mesure du déplacement des couples de rouleaux.
摘要:
A compound disc is used to eliminate a secondary slot normally formed between adjacent shafts of a material separation screen. The compound disc comprises a primary disc joined to an associated secondary disc. The primary disc and the secondary disc each have the same shape but the secondary disc has a smaller outside perimeter and is wider. The primary disc and associated secondary disc are formed from a unitary piece of rubber. The compound discs are interleaved with oppositely aligned compound discs on adjacent shafts. In other words, the large disc is positioned on a shaft to align with a smaller disc on an adjacent shaft. The oppositely aligned and alternating arrangement between the large discs and small discs reduce problems that exist in screens that use in-line multi-sided discs.
摘要:
A waste paper sorting conveyor for sorting waste paper from waste cardboard has a sorting bed formed by a row of rotatable, driven shafts (7) mutually spaced in a conveying direction (8) and each extending transversely to the conveying direction (8). The shafts (7) each carry a row of impellers (9) for intermittently urging material on the sorting conveyor upwards and in the conveying direction (8). The impellers (9) of each of the rows are mutually spaced in the longitudinal direction of the respective shaft (7). Rotary contours of impellers (9) carried by each of the shafts (7) project between rotary contours of the impellers (9) carried by a neighbouring one of the shafts (7). Since the mutual spacing of the impellers (9) of at least one of the rows in the longitudinal direction of the respective shaft (7) is adjustable, waste paper and waste cardboard mixtures of varying compositions can be sorted to an improved purity.
