Abstract

A method is for the presentation of fibre flows in foreign part detection machines. The fibres (1) are guided into a chute and transported past colour sensors (2) by means of a transport belt or roll (3). The narrowest point of the chute is not rigid and the flexibility of at least one of the chute wall eliminates clogging.

Description

Es sind Maschinen bekannt, mit denen in Faserverarbeitungslinien der baumwollverarbeitenden Industrie andersfarbige Fremdteile aus Faserströmen erkannt und ausgeschleust werden. Bei diesen Maschinen werden die Fasern in einen Schacht abgeschieden und verdichtet. Der verdichtete Faserstrom wird an Farbsensoren oder Kameras vorbei geleitet und analysiert. Werden hierbei Fremdteile erkannt, so werden diese gezielt ausgeschleust. Problematisch ist hierbei die Präsentation der Fasern für die Sensoren. Aufgrund der unregelmäßigen Faserbeschaffenheit z. B. Faserverklumpungen kann es hier bei schmalen Schachttiefen zu Verstopfungen kommen. Bei zu breiten Faserströmen ist aber eine zuverlässige Fremdteildetektion nicht mehr möglich. Aufgabe der Erfindung ist es, eine konstruktive Lösung zu schaffen, die einen störungsfreien Transport der Fasern entlang der Sensoren ermöglicht. Erfindungsgemäß wird dies durch ein den Sensoren gegenüberliegendes flexibel gelagertes Transportmittel, das z. B. ein Transportband oder eine Transportwalze sein kann, erreicht (Fig. 1). Die Fasern (1) werden durch die zwischen der nicht bewegten Sensoreinheit (2) und dem bewegten Transportmittel (3) herrschenden Relativgeschwindigkeit an den Sensoren vorbei transportiert. Durch eine selbsttätige automatische Regelung der Spalttiefe t während des Transportvorganges können Verstopfungen vermieden werden. Durch ein flexibles Transportband bzw. flexible Lagerung der Transportwalzen kann die Transporteinheit eventuell auftretenden Faserverklumpungen ausweichen. Nach dem Passieren dieser Faserklumpen geht das Transportmittel sofort selbsttätig wieder in die für eine zuverlässige Detektion optimale Lage zurück. Eine andere Möglichkeit ist die bewegliche Lagerung der Sensoreinheit, so daß sie bei Verstopfungsgefahr ausweicht. Bei einer Segmentierung der Sensoreinheit, bei der jedes Sensorelement oder Gruppen von Sensorelementen einzeln flexibel gelagert ist, kann genau das Element, bei welchem eine Verstopfung auftreten würde, ausweichen und somit kann die optimale Schachtbreite für die anderen Segmente aufrecht erhalten werden.Machines are known with which foreign-colored parts from fiber streams in fiber processing lines of the cotton-processing industry are recognized and discharged. With these machines, the fibers are separated into a shaft and compacted. The compressed fiber stream is directed past color sensors or cameras and analyzed. If foreign parts are recognized, they are specifically removed. The presentation of the fibers for the sensors is problematic here. Due to the irregular fiber quality z. B. Clumping of fibers can lead to blockages in narrow shaft depths. If the fiber streams are too wide, reliable detection of foreign parts is no longer possible. The object of the invention is to provide a constructive solution that enables trouble-free transport of the fibers along the sensors. According to the invention, this is achieved by a flexibly mounted means of transport opposite the sensors, which, for. B. can be a conveyor belt or a transport roller, reached ( Fig. 1). The fibers ( 1 ) are transported past the sensors by the relative speed prevailing between the non-moving sensor unit ( 2 ) and the moving transport means ( 3 ). Blockages can be avoided by an automatic, automatic regulation of the gap depth t during the transport process. The transport unit can avoid any fiber clumping that may occur due to a flexible conveyor belt or flexible mounting of the transport rollers. After passing through these clumps of fibers, the means of transport automatically returns to the optimal position for reliable detection. Another possibility is the movable mounting of the sensor unit so that it avoids the risk of clogging. In the case of segmentation of the sensor unit, in which each sensor element or groups of sensor elements is individually flexibly mounted, exactly the element in which blockage would occur can deviate and the optimum shaft width for the other segments can thus be maintained.

Methode zur Präsentation von Faserströmen in Fremdteildetektionsmaschinen dadurch gekennzeichnet, daß die Fasern in einen Schacht geleitet werden und durch ein mechanisch bewegtes und an den Sensoren vorbei bewegendes Transportmittel, welches z. B. ein Transportband oder eine Transportwalze sein kann, an Farbsensoren vorbei transportiert werden, wobei dieser Schacht an seiner engsten Stelle nicht starr ist, sondern mindestens eine der Schachtwände, also das Transportmittel oder die Sensoreinheit, flexibel bzw. flexibel gelagert ist, und so Faserverklumpungen und anderen Verstopfungsgefahren selbsttätig und automatisch ausweicht und nach Passieren dieser Störungen auch selbsttätig wieder in die Ausgangslage zurückkehrt.Method for the presentation of fiber streams in foreign part detection machines, characterized in that the fibers are guided into a shaft and by a mechanically moved and moving past the sensors means of transport, which z. B. can be a conveyor belt or a transport roller, transported past color sensors, this shaft is not rigid at its narrowest point, but at least one of the shaft walls, i.e. the means of transport or the sensor unit, is flexibly or flexibly mounted, and thus fiber clumping and other dangers of constipation automatically and automatically evacuates and automatically returns to the starting position after passing through these faults.
