Title
(EN) ASSEMBLY AND METHOD FOR REDUCING DOFFING TIME FOR SET OF BOBBINS ON RING SPINNING MACHINE
(FR) ENSEMBLE ET PROCÉDÉ POUR LA RÉDUCTION DU TEMPS DE LEVÉE D'UN ENSEMBLE DE BOBINES SUR UNE MACHINE À FILER À ANNEAUX
Abstract
(EN) The present disclosure pertains to an assembly (100), and a method (800) for reducing doffing time for one or more set of bobbins. The assembly (100) includes a set of rail plates (102) adapted to accommodate one or more gripper bobbin holders (104), and facilitates replacing set of full bobbins (202) with set of empty bobbins (204) on ring spinning machine. The assembly (100) enables gripping the set of full bobbins (202) by means of self-operated bobbin holder (104) from top inner side and replacing with the set of empty bobbins (204) through rotation of one hundred and thirty five degrees to two hundred and twenty five degrees degree in addition to lifting and lowering the assembly. The assembly (100) enables operating in line with the ring spinning machine width and is safe and requires less space for operation.
(FR) La présente divulgation concerne un ensemble (100), et un procédé (800) permettant de réduire le temps de levée d'un ou plusieurs ensembles de bobines. L'ensemble (100) comprend un ensemble de plaques de rail (102) conçues pour recevoir un ou plusieurs supports de bobine à pince (104), et facilite le remplacement de l'ensemble de bobines pleines (202) par un ensemble de bobines vides (204) sur la machine à filer à anneaux. L'ensemble (100) permet la saisie de l'ensemble de bobines pleines (202) au moyen d'un porte-bobine à commande autonome (104) depuis le côté interne supérieur et le remplacement par l'ensemble de bobines vides (204) par une rotation de cent trente-cinq degrés à deux cent vingt-cinq degrés en plus du soulèvement et de l'abaissement de l'ensemble. L'ensemble (100) permet un fonctionnement aligné à la largeur de la machine à filer à anneaux, et est sûr et nécessite moins d'espace pour le fonctionnement.
