Device for processing threads or yarns of textile fibers

Abstract

A device for processing threads or yarns of textile fibers includes a supporting structure for at least one spool for feeding a thread or a yarn of textile fibers and at least one textile machine, associated with a control panel, which uses the thread or yarn unwound from the at least one feeder spool. The device also includes a supporting structure for weighing the feeder spool, which is functionally connected to a control and actuation device. The weighing device is associated with protection elements adapted to avoid excessive stresses of the weighing device during the operations for loading and/or unloading the feeder spool onto and/or from the supporting structure.

         14 . A device for processing threads or yarns of textile fibers comprising: a supporting structure for at least one spool for feeding a thread or a yarn of textile fibers and at least one textile machine, associated with a control panel, which uses the thread or yarn unwound from said at least one feeder spool, said supporting structure being associated with a device for weighing said at least one feeder spool, which is functionally connected to a control and actuation device, wherein said weighing device is associated with protection means adapted to avoid excessive stresses of said weighing device during the operations for loading or unloading said at least one feeder spool onto or from said supporting structure. 
     
     
         15 . The device according to  claim 14 , wherein said weighing device comprises at least one load cell, which comprises a cell body that can move along a movement path as the weight of the respective feeder spool varies in contrast with elastic means associated with said cell body, said protection means comprising a mechanical stop device that is adapted to limit the movement of said cell body along said movement path. 
     
     
         16 . The device according to  claim 14 , wherein said mechanical stop device is adjustable on command. 
     
     
         17 . The device according to  claim 14 , wherein said weighing device comprises at least one accelerometer, said protection means comprising a supporting body for said feeder spool, said protection means comprising an engagement portion that is defined at said supporting body for said accelerometer, said accelerometer being adapted to detect the weight of the feeder spool associated with said supporting body. 
     
     
         18 . The device according to  claim 15 , wherein said stop device is associated with means of automatic activation/deactivation functionally connected to said control and actuation device. 
     
     
         19 . The device according to  claim 14 , further comprising at least one temperature detection sensor. 
     
     
         20 . The device according to  claim 14 , further comprising at least one humidity detection sensor functionally associated with said control and actuation device. 
     
     
         21 . The device according to  claim 15 , wherein said load cell comprises a flexural load cell, said elastic means comprising said cell body. 
     
     
         22 . The device for processing threads or yarns according to  claim 14 , further comprising a supporting structure for a plurality of feeder spools, each feeder spool being associated with a respective weighing device. 
     
     
         23 . The device according to  claim 14 , wherein said control and actuation device is interfaced with a control panel which comprises a monitor associated with said textile machine or a portable display and control device comprising a tablet computer, a smartphone or a similar device. 
     
     
         24 . The device for processing threads or yarns according to  claim 14 , wherein said control panel is adapted to control said textile machine to produce a preset number of textile products, said weighing device being adapted to measure a corresponding change in weight of said at least one feeder spool as a consequence of the production, by said textile machine, of said preset number of textile products. 
     
     
         25 . The device for processing threads or yarns according to  claim 23 , wherein said weighing device is adapted to send a signal to said control and actuation device or to said control panel if the quantity by weight of thread or yarn wound on the respective feeder spool is lower than a preset reference value. 
     
     
         26 . The device for processing threads or yarns according to  claim 23 , wherein said control and actuation device or said control panel is adapted to halt said textile machine following the reception of said signal from said weighing device.
