Abstract

PURPOSE:To draw-out thread in high speed with a high constant tension by taking-up thread onto a thread taking-up drum by revolving a member equipped with bobbin and the thread taking-up drum and storing thread. CONSTITUTION:A thread taking-up member 15 is installed rotatably, and a thread taking-up drum 17 is supported rotatably, and the thread taking-up drum 17 is revolved in the reverse direction to the direction of revolution of the thread taking-up member 15. Therefore, when each revolution speed of the thread taking-up member 15 and the thread taking-up drum 17 is selected at each table max. speed, the speed of the thread taken-up onto the outer periphery of the thread taking-up drum 17 becomes the sum of the both above-described, and the following value is permitted; 800m/min+1,200m/min=2,000m/min, and the thread taking-up speed can be increased markedly. When little amount of thread is left on a thread taking-up part 171, the output of a sensor 2 is zero, so a motor 14 is revolved, and the thread 1a fed onto the edge part 151 of the thread taking-up member 15 is introduced into the edge part 152 of the other, and taken-up onto the outer periphery of the thread taking-up part 171. In this case, a drum shaft 173 is revolved in the reverse direction to a spindle 12.

Description

[Detailed description of the invention]

This invention relates to a thread storage/drawing device, and more particularly to a thread storage/feeding device. As is well known, a yarn storage/unwinding device is used to supply the weft while maintaining a constant tension.・Feeding devices are used not only for mechanical N yarn supply, but also for winders, etc. Conventionally known yarn storage/feeding devices q include a bobbin drum rotating type, a thread type (S) av
There are two types of fishing: the so-called Sulzer type, which has a stationary bobbin drum, and the Sulzer type, which has a stationary bobbin drum. By rotating the bobbin drum, a predetermined amount of thread is wound around the outer circumference of the bobbin drum and stored.When the loom is operating, the thread is unwound from the bobbin drum while maintaining a constant tension. At the same time, the peg drum rotates to replenish the lack of CvN-spun yarn. That is, the thread on the peg drum is simultaneously wound and replenished while being pulled out. Through-the-type thread storage/91
At output 1'-ri, the bobbin drum is kept stationary and the bobbin winding drum 1 is
Rotate one part to place the thread on the bobbin drum at a predetermined 0? #Phrase 1 noru. At the same time as the yarn begins to be unwound, the bobbin winder 11 member starts to replenish the insufficient yarn. Next, we will discuss the characteristics, advantages and disadvantages of both. One of the advantages of storing and feeding out ribbed yarn is that the bobbin drum is always kept in a rotating state, so even when the yarn is being fed out intermittently, the yarn is constantly swung around, which prevents snarling from forming.
Suitable for yarn. However, when the yarn speed exceeds Boom/min, when the tension ring is inserted into the rotating bobbin drum 1 and used, the fingers of the tension ring spread due to centrifugal force and the tension decreases. This includes the problem that you end up with no tension. For this reason, the 4-knot type is a yarn that can be used practically.
・■ is 1! , limited to 90011/' minutes, no more than that! On the other hand, in the sluzer type yarn storage/feeding device, the yarn τ citrum is stationary, so when the yarn is fed out intermittently, the yarn hangs down and rests, resulting in the formation of snarls. However, when the yarn speed is Boom/min or more, C also has the characteristic that there is no change in tension because the string 1 ring remains stationary. Speed is 1.200+!
If the time is 1.7 minutes or more, the winding speed of the thread becomes too high and the thread is likely to break, which is dangerous. Therefore, the rust type is suitable for yarn speeds as low as 8001D/'', while the through f type is suitable for yarn speeds of 800m or more.However, in any case, the yarn speed is is 1 + 200
+++ There was a drawback that it could not be applied to high-speed feeding for more than 7 minutes. Therefore, the purpose of this invention is to eliminate the drawbacks of both the shim rotating type and the bobbin drum holding system by 1.4 yen, and to exhibit the characteristics of both, and to reduce the yarn speed to 1.20 (
It is an object of the present invention to provide a yarn storage/glue dispensing device U that enables high-speed unwinding with a constant tension even at high speeds of E1/min or higher. In summary, the present invention includes: a thread winding member rotatably installed; a thread winding drum rotatably supported; and a direction IX opposite to the rolling direction of the thread winding member; By configuring it so that it is rotationally driven, the rotational speeds of the bobbin winding member and the bobbin drum can be selected at stable maximum speeds.

[The speed of the thread being pulled is the sum of the two, so it is 80 qm/min. 1-1200 m.
