Abstract

PURPOSE:A twister that is provided with a rotary part of compactness and light weight so that the undrawn yarns taken out of the packages hung on creels or the like are subjected to first twisting separately and combined together under simultaneous finish twisting, thus enabling high-speed operation. CONSTITUTION:A plurality of undrawn yarns 5, 5... are false-twisted with back rollers 7, while an untwisted yarn for first twisting 5b is made to run straightforward through the guide tube 1 and supported with the yarn guide 23 and tension compensator 24 in the untwisted state. The first-twisted yarn 5a is made to run through the guide tube 1 separately from the yarn 5b in the false-twisted state and they are combined with the collection guide 9. Both of the yarns 5a, 5b tangle with each other to give the double-twisted yarn 25 which has been finish-twisted in the reverse direction to the first twisting at the same twisting number.

Description

[Detailed Description of the Invention] The present invention is capable of simultaneously adding ply twist to a plurality of yarns while applying ply twist to the raw yarn to form a ply-twisted yarn, that is, ply-twisting and ply-twisting can be simultaneously twisted using a single device. This invention relates to a heating device.

Conventionally, heating devices for fizzy yarn that apply first twist to the raw yarn, then combine multiple yarns and then final twist them all load a raw yarn package onto a rotating spindle and connect the first twist heating section and the final twist. It has a complex structure with two sets of rotating parts, including a heating part.For example, as yarn packages become larger, such as those used in industrial materials such as tire cords, the heating equipment becomes larger and power consumption increases. There were drawbacks such as rapid increase in the number of machines, impossibility of speeding up, low productivity, and high equipment costs due to rough spindle gauges. Furthermore, when replenishing yarn, the heating device must be stopped, new yarn must be loaded, and splicing must be performed, resulting in low operational efficiency.

An object of the present invention is to eliminate the above-mentioned drawbacks.

That is, this invention has a structure in which yarns pulled out from a yarn package placed on a yarn support unit such as a creel can be separately twisted while simultaneously being twisted and plied to perform combined twisting. This is a heating device that is compact and consumes less power, and is capable of increasing speed, increasing operating efficiency, and reducing costs.

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the heating device of the present invention includes a conduit 1 extending through the axis, and a yarn branching chamber 2 in the middle of the conduit 1.
is provided, and a conical disk 3 that opens forward (in the exit direction of the yarn) is attached to this part, and a heating spindle part A that rotates in the direction of the arrow 3 at a required speed is installed at the rear of this spindle part A. A yarn support section B on which a plurality of yarn packages 4 are placed and the yarns 5 pulled out from them are arranged and supplied; and a yarn guide installed in front of the spindle section for yarns that have gone straight from the conduit 1. 23, tension compensator 24, mHEt+ front roller 6
It consists of a doubling part C consisting of etc.

The spindle part A has a bow-aligned yarn 5 at the rear end of the conduit 1.
A heating pack roller 7 is attached for heating the disk 3, and a plurality of yarn guide tubes 8 communicating with the yarn branching chamber 2 are provided in the disc 3 radially around the yarn branching chamber 2.

A convergence guide 9 is attached to the yarn doubling section C near the rear of the front roller 6.

According to the heating device, the rolled yarn 5 pulled out from the yarn support part B is false twisted by a pair of pack rollers 7, as shown in FIG. One of the untwisted and untwisted yarns 5b travels straight through the conduit 1 and is supported by the yarn kite 23 and the tension compensator 24 and remains untwisted, while the other untwisted and heated yarn 5a remains heated by the pack roller 7. The untwisted and untwisted yarn 5b travels in the conduit 1 in a separated state, passes through the yarn branching chamber 2 and the yarn guide tube 8 of the disk 3, and exits from the front end yarn outlet 1] 10 of the conduit 1 and passes through the convergence guide 9. Using a fulcrum, the yarn 5a is heated to the same number of first twists in the same direction, and is combined with the first twisted and untwisted yarn 5b by the convergence guide 9, and both yarns are intertwined and heated to the same number of first twists in the opposite direction to the first twist. will be done.

The spindle part A is attached to a 7-frame frame 11 of the machine via a bearing 12, and is driven by a conductive tape 14 hung on a warb 13 to a rotation speed corresponding to the number of twists to be heated. A trumpet-shaped yarn guide 16 is attached just before the pack roller 7, and is rotatably supported by the disk 3 in pressure contact with the disk 3.
A yarn outlet 1'' 10 is attached to the end of the yarn guide tube 8.

The yarn support section B includes a creel (not shown) that supports the yarn package 4, a tension compensator 17 through which the yarn passes, a yarn guide 1' 18, and a convergence guide 19.

As shown in FIGS. 1 and 3, the yarn doubling section C has a central window 21 on a disc-shaped stationary base 20 fixed to the spindle blade 26 via a bearing 12' at the front part toward the spindle section. A hemispherical cover 22 with a hemispherical cover 22 is attached, and a pair of yarn guides 23 and a tension compensator 24 are attached inside this cutter 22.

This stationary base 20 has two weights at the bottom.
7 is attached to maintain a stable state and prevent the stationary base 20 from rotating due to friction or the like against the spindle portion. The front roller 6 is a pair of driving rollers that can unwind the twisted yarn 25 at a required yarn speed, and supplies the twisted yarn 25 to a winding device (not shown) in front of the roller.

The heating device according to the present invention has the above-described structure. When using this device, when a plurality of raw yarns 5 to be twisted and twisted are supplied to the spindle section A, the heating device is heated by the front roller 6 to be driven. While traveling at a required yarn speed, the first-twist heated yarn 5a, which is heated as a second twist to the position of the convergence guide 9 by the nogutsu crawler 7, is transferred to the conduit 1, the yarn branching chamber 2 for pulling, and the yarn guide tube of the disk 3. The yarn passes through the axial conduit 1 in the convergence guide 9 while exhibiting luning after passing through the yarns 8 and is heated by the convergence guide 9 to the same pre-twist as the yarn 5a. Twisted yarns 25 of the same number of loosely twisted yarns in the reverse direction as the first twist are obtained. Twist this twisted yarn 25 & (
T/m) is, of course, the rotation Yc (r
ptn)÷surface speed of front roller 6 (m/m
in).

In addition, this heating device is suitable for twisting three or more yarns.
The pre-twist heated yarn 5a is passed through the plurality of radial yarn guide tubes 8 of the disk 3.
The first twisted and untwisted yarn 5b is passed through the conduit 1.

As described above, according to the heating device of the present invention, the rotating part is very compact and has a large eaves, and the power consumption is extremely low, allowing for high speed operation and a significant reduction in production costs. In addition, it is possible to make large packages of raw yarn using thick yarn such as tire cord yarn or carpet yarn, and it can be handled without any problems regardless of the shape or size. The gauge is also narrower (equipment costs can be reduced compared to conventional products), and since the creel at the yarn support is fixed, there is no need to stop the machine to replenish the yarn package, greatly improving operating efficiency. There are many effects such as -L and greatly contributing to Cost Town.
