Sample warper with series yarn guide mechanism and warping method

Abstract

There is provided a sample warper with a series yarn guide mechanism comprising: a warper drum; a plurality of conveyor belts movably provided on a peripheral side face of the warper drum; a plurality of yarn guide units arranged in series opposing to a front face of the warper drum, and a plurality of yarn feed bobbins each mounted on the respective yarn guide units, wherein the plural yarn guide units each repeats rotation and suspension thereof, whereby yarns pulled out from the yarn feed bobbins are wound on the conveyor belts in a preset yarn arrangement order. According to the present invention, such an advantage can be achieved that installation of the conventional yarn selection device can be omitted, such troubles as yarn loosening during yarn exchanging, failure in yarn selecting operation, and suspension due to yarn breaking when yarn selecting or the like can be solved, and pattern warping performed by simultaneous warping of a plurality of yarns is made possible so that the warping can be performed efficiently in a short time.

1 . A sample warper with a series yarn guide mechanism comprising: a warper drum; a plurality of conveyor belts movably provided on a peripheral side face of the warper drum; a plurality of yarn guide units arranged in series opposing to a front face of the warper drum, and a plurality of yarn feed bobbins each mounted on the respective yarn guide units, wherein the plural yarn guide units each repeats rotation and suspension thereof, whereby yarns pulled out from the yarn feed bobbins are wound on the conveyor belts in a preset yarn arrangement order.  
   
   
       2 . The sample warper with a series yarn guide mechanism according to  claim 1 , wherein the yarn guide units are rotatably mounted on a yarn guide main shaft arranged on the center line of the front face of the warper drum.  
   
   
       3 . The sample warper with a series yarn guide mechanism according to  claim 1 , wherein each of the yarn guide units is provided with a driving means for the yarn guide unit.  
   
   
       4 . The sample warper with a series yarn guide mechanism according to  claim 2 , wherein each of the yarn guide units is provided with a driving means for the yarn guide unit.  
   
   
       5 . The sample warper with a series yarn guide mechanism according to any one of  claims 1  to  4 , wherein the feed rate of the conveyor belt varies in accordance with the number of the yarn guide units rotating simultaneously.  
   
   
       6 . A warping method using the sample warper with a series yarn guide mechanism according to  claim 1 , wherein pattern warping is performed by rotating the plural yarn guide units each mounted with the yarn feed bobbin in accordance with a directed yarn arrangement order on the basis of preset pattern data.  
   
   
       7 . The warping method according to  claim 6 , wherein the pattern warping is performed by rotating yarn guide units mounted with yarn feed bobbins to be used in accordance with the yarn arrangement order, yarn guide units mounted with yarn feed bobbins not to be used being temporarily suspended at predetermined positions.  
   
   
       8 . The warping method according to  claim 7 , wherein a distal end guide member of each of the yarn guide units, which are temporarily suspended at the predetermined positions, is displaced to positions deviated from a yarn winding orbit.
