Title (EN) METHOD AND APPARATUS FOR PRODUCING MEASURING VALUES CORRESPONDING TO THE LINEAR DENSITY OF FIBRE SLIVERS
(FR) METHODE ET APPAREIL D"ETABLISSEMENT DE VALEURS DE MESURE CORRESPONDANT A LA DENSITE LINEAIRE DE MECHES DE FIBRES
Abstract: front page image
(EN)The inventive method is used for producing of measuring values depending on the linear density of a fibre sliver transported through a measuring funnel. A measuring signal transmitted from the measuring funnel (2) is transformed into a proportional electric voltage signal and is continually integrated. The inventive apparatus comprises the so-called measuring funnel connected pneumatically with a pneumatic/electric transducer (4). The transducer transmits its signal to an integration circuit arrangement (6). A control logic device (13) on one hand cooperates with a gear (11) of a gear arrangement (10) of a spinning preparatory machine and on the other hand is connected with the integrating circuit arrangement. A proximity initiator (12) transmits an impulse to the control logic arrangement at each passage of a tooth. The integrating circuit supplies measuring values suitable as a control signal for spinning preparatory machines, which signal is independent of the speed of the fibre sliver.
(FR)La methode est utilisee pour etablir des valeurs de mesure en fonction de la densite lineaire d"une meche de fibres transportee au travers d"un entonnoir de mesure. Un signal de mesure transmis de l"entonnoir de mesure (2) est transforme en un signal de tension electrique proportionnel et est integre de maniere continue. L"appareil de l"invention comprend l"entonnoir de mesure en question connecte pneumatiquement a un transducteur pneumatique/electrique (4). Le transducteur transmet son signal a un dispositif de circuit d"integration (6). Un dispositif logique de commande (13) d"une part coopere avec une roue dentee (11) d"un dispositif d"engrenage (10) d"une machine preparatoire a filer et, d"autre part, est connecte au dispositif de circuit d"integration. Un initiateur de proximite (12) transmet une impulsion au dispositif logique de commande a chaque passage d"une dent. Le circuit d"integration fournit des valeurs de mesure sous forme de signaux de commande a des machines a filer de preparation, lesdits signaux etant independants de la vitesse de la meche de fibres.
