Embodiment Construction

[0046] Next, embodiments of the present invention will be described. Additionally, the figure 1 The up and down direction on the paper is set as the up and down direction (vertical direction of gravity). Will figure 1 The left-right direction of the paper is set to the left-right direction. Will figure 1 The vertical direction of the paper is set as the front-back direction.

[0047] (spinning traction machine)

[0048] refer to figure 1 The configuration of the spinning take-up machine 1 including the induction heating roll 20 according to the present embodiment will be described. figure 1 is a schematic view of the spinning take-up machine 1 viewed from the front side. The spinning take-up machine 1 is configured such that a plurality of yarns Y (the object to be heated in the present invention) spun from the spinning device 2 are stretched by the spinning drawing device 3 and then passed through the yarn winding device 4 . Do coiling.

Abstract

The invention relates to an induction heating roller and spinning stretching device. An object of the present invention is to effectively reduce the temperature dispersion of a cylindrical portion of a roller main body in the axial direction of the induction heating roller. The induction heating roller 20 includes a rotatable roller unit 30 and a coil 52. The roller unit 30 includes a roller main body 31 provided with an outer cylindrical portion 34 (cylindrical portion) extending in an axial direction of the roller unit 30, wherein the outer cylindrical portion 34 is induction-heated when a current flows in the coil 52; a heat equalizing member 32 which is able to transfer the heat generated in the outer cylindrical portion 34 in the axial direction and which more easily transfers the heat in the axial direction than the outer cylindrical portion 34 does, and a heat generating member 60 which is provided at an end portion of the outer cylindrical portion 34 in the axial direction and which is induction-heated when a current flows in the coil 52. The heat generating member 60 is made of a material which is lower in electric resistivity than a material forming the outer cylindrical portion 34 and a material forming the heat equalizing member 32. The heat generating member 60 is provided to be adjacent to at least one of the outer cylindrical portion 34 and the heat equalizing member 32.

Description

technical field [0001] The present invention relates to an induction heating roll and a spinning and drawing device equipped with the induction heating roll. Background technique [0002] Patent Documents 1 and 2 disclose an induction heating roller for heating an object to be heated (thread, toner, etc.). The induction heating roller includes a coil and a roller (hereinafter referred to as a roller unit) having an outer cylindrical portion (hereinafter referred to as a cylindrical portion) which is induced to be heated. When magnetic flux is generated by flowing an alternating current through the coil, an eddy current is generated in the circumferential direction of the cylindrical portion of the roller unit by electromagnetic induction, and the cylindrical portion generates heat due to Joule heat. By such induction heating, the object to be heated that is in contact with the roller unit is heated. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2018-35488 [0...
