Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared radiation thermometer for measuring temperature by thermal radiation, and in particular, to various filaments such as a thread composed of thermoplastic synthetic fibers such as polyester and polyamide, and a metal wire. The present invention relates to a technology for measuring the temperature of an object.

[0002]

2. Description of the Related Art Conventionally, there is a so-called draw false twisting machine for processing thermoplastic synthetic fibers such as polyester and polyamide as a thread. The draw false twister travels a bundle (hereinafter, referred to as a raw yarn) in which a plurality of continuous very long single fibers (filaments) are combined from a supply roll toward a take-up roll (for example, for one minute). About 700m
While the raw yarn is being stretched, the false twist is given by the false twist device while stretching the raw yarn, and the non-contact heat processing is applied to the raw yarn at the heater section on the upstream side of the false twist device to shrink and expand and contract the raw yarn. Manufactures highly processed yarns. A woven fabric or the like made from the processed yarn has a unique texture. In addition, the temperature control for heating the running yarn is performed by monitoring and controlling the heater temperature of the heater unit to adjust the amount of heat radiation.

[0003]

However, the above-mentioned conventional apparatus has the following problems. That is, the radiation effect of the heater unit may be reduced due to lint accumulated on the heater, processing oil mist, or the like, but it cannot be detected by monitoring the temperature of the heater unit. There's a problem. Such a decrease in the radiation effect of the heater portion is directly reflected on the processed yarn, causing variations in the properties of the processed yarn and deteriorating the quality of the processed yarn.

Therefore, an infrared radiation thermometer capable of directly measuring the temperature of the raw yarn immediately after thermal processing, instead of monitoring the heater temperature of the heater section, has been considered. This infrared radiation thermometer matches a detection spot for detecting infrared rays (the diameter of this detection spot is, for example, about 1 mm) with the original yarn immediately after thermal processing (the diameter of the original yarn is, for example, 100 to 200 μm or less). In such a manner, the temperature of the original yarn is measured by detecting infrared rays in a detection spot of the original yarn, and is provided at a fixed measurement position immediately after passing through the heater section. However, in this infrared radiation thermometer, it is necessary to measure the temperature of the fine yarn while maintaining the state where the minute detection spot is matched with the fine yarn.
The fixed measurement position for measuring the temperature of the yarn immediately after the heat processing cannot be easily changed to another measurement position, and a single infrared radiation thermometer is used to measure the yarn at a plurality of measurement positions. There is a problem that the temperature cannot be measured quickly and portability is lacking. Also, usually, the draw false twisting machine described above is composed of a plurality of draw false twisting units, thereby increasing the productivity of the processed yarn. There is a problem of having to prepare. Therefore, there is no portable infrared radiation thermometer for the filament, and a portable infrared radiation thermometer for measuring the temperature of the filament is desired.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a portable infrared radiation thermometer capable of measuring a temperature at an arbitrary position of a filament. .

The present invention has the following configuration to achieve the above object. That is, the infrared radiation thermometer according to claim 1 includes a measuring device main body that detects infrared rays from the filament and measures the temperature of the filament, and a filament based on measurement data from the measuring device main body.
