Winder

Abstract

In a winder 1, as an amount of yarns Y wound onto bobbins B increases, a turret table 3 rotates in the direction in which a bobbin holder 2 moves away from a contact roller 11. A tilt mechanism 5 transfers, by a cam 31, a cam rod 32, a force multiplying arm 33, a tie rod 34, and a tilt arm 35, the rotation of the turret table 3 to a guide shaft 13 elevatably supports a supporting member 12, so as to tilt the guide shaft 13. As a result, as the amount of the yarns Y wound onto the bobbins B attached to the bobbin holder 2 is increased and the bobbin holder 2 is warped, the contact roller 11 supported by the supporting member 12 is tilted.

Description

technical field [0001] The invention relates to a winding machine for winding yarn onto bobbins. Background technique [0002] In the winding machine described in Patent Document 1, contact rollers (touch rollers) extending parallel to the bobbin holder are brought into contact with a plurality of bobbins mounted on the bobbin holder supported by a cantilever. The rollers apply contact pressure to the bobbin while winding the yarn onto the bobbin. [0003] Here, in such a winder, as the amount of yarn wound onto the bobbin by the contact roller increases, the bobbin holder is closer to the front end portion farther from the supported portion due to the weight of the yarn. Flex downward. [0004] Therefore, in the winding machine described in Patent Document 1, the contact pressure of each bobbin is detected, and the adjustment cylinder is extended or retracted according to the detection result, thereby changing the pressure applied to the contact roller, and the contact pr...

AI Technical Summary

Problems solved by technology

[0006] However, as in Patent Document 1, by detecting the contact pressure of each bobbin and changing the pressure applied to the touch roller by the adjustment cylinder according to the detection result, thereby tilting the touch roller, if the yarn If the adjusting cylinder is damaged during the winding process, the pressure exerted by the adjusting cylinder on the touch roller changes rapidly. Vibration occurs on the touch roller, causing damage to the mounting part of the touch roller, etc.
