ES443920A2 - Automatic doff and start-up control apparatus for textile yarn processing machine - Google Patents

Abstract

Improvements in the object of the main patent no. 430,965 by "perfeccionamientos in textile machines to elaborate thread, such as the spinning and twisting machines, which have a fixed frame, rotary thread receiving spindles supported by the mentioned frame, a swing arm with upward and downward vertical movement around the mentioned spindles for guiding the thread being processed in coils supported by said spindles in predetermined patterns to form processed spinning coils, thread guiding means associated with each of the aforementioned spindles for guiding said thread on said rocker arm and on said spindles during the thread processing, and movement mechanisms of the former including a crank arm pivotally mounted on said machine frame and operatively connected to said guide rocker -threads for alternative movement on pivot of the same mo to alternately move the aforementioned guide-wire rod in previously determined types, characterized by comprising the combination with control devices for automating the movements of the said spinning machine to prepare the said spinning machine to move the filled bobbins of processed spinning and for the start of new processed spinning coils, whose apparatus comprises: Means connected to said mechanism of movement of the former of said machines, only and sequentially, to (l) lower said rocker to a coil molding position below the coils of said spindles; (2) assist said rocker to climb under the influence of the aforementioned movement mechanisms of the former to a spinning position near the bottom of the coils of said spindles and (3) to lower and intermittently move said rocker up and down near the bottom of the coils of the mentioned spindles to eliminate the sine of the thread and for the formation of coils during start-up; A latch element mounted with a pivot on said frame of the machine for the movement of locking and from the locking position connected with said rocker when in the position of shedding of coils and including means of solenoid coils connected thereto to move said latch element; Means pivotally mounting each of said yarn guides in said frame for pivotal movement to and from a yarn processing position, generally axially above said spindles to and from a molting position, generally spaced apart of the axes of said spindles for the molding of the said spindles and having hydraulically operated means connected thereto and with said rocker, controlling the hydraulically operated means to be driven by it to move the mentioned thread guides to and from the positions of change of the same in relation to the position of the mentioned seesaw; Control means for synchronized electrical circuit, operatively connected with said rocker controlling the hydraulically actuated means and said means of selenoid for the bolt to be driven by predetermined positions of said rocker to drive and control the proper positioning of said rocker, of the aforementioned latch element and of the aforementioned thread guides for the molding and the start-up of said spinning machines; Creative means of rearming movement connected with the aforementioned movement mechanisms of the former and directed by the position of said rocker in the molting position to automatically rearm the aforementioned movement mechanisms of the former.
