Abstract

This study relates to a sensor for trimming detection using a laser. More specifically, a thread wound on a regular machine moves to a weaving machine and weaves the fabric, which is installed on both sides of the weaving machine to detect the trimming. The other side is composed of a light receiving unit for receiving the laser. The present invention relates to a laser light emitting unit and a light receiving unit. The laser beam emitted from the laser module passes through a conduit formed in the case of the laser module to send a laser and is formed in the light receiving unit case. The objective is to detect that the laser is more efficiently trimmed by sending and receiving the laser so that the focus is uniformly formed by receiving it through the receiver.

Description

Trimming sensor using semiconductor laser {LASER SENSER}

This study relates to a sensor for trimming detection using a laser. More specifically, a thread wound on a regular machine moves to a weaving machine and weaves the fabric, which is installed on both sides of the weaving machine to detect the trimming. The other side is composed of a light receiving unit for receiving the laser. The present invention relates to a laser light emitting unit and a light receiving unit. The laser beam emitted from the laser module passes through a conduit formed in the case of the laser module to send a laser and is formed in the light receiving unit case. The purpose of this is to detect the trimming more efficiently by receiving and sending the laser so that the focus is uniformly formed by receiving it, and to detect the trimming more efficiently in accurately receiving the laser in consideration of a certain amplitude of vibration.

Conventional commercially available lasers are not uniform, and in order to obtain a constant laser, a separate expensive lens is installed and passed through and received there, so that a constant focus cannot be obtained and a cost is high.

In order to eliminate the above drawbacks, the present invention forms an arbitrary pipeline in the laser module case, allows the laser to pass through, and receives an arbitrary pipeline in the light receiving unit case. The focus is on making sure that

In the process of loosening the yarn strand 2a from the yarn 2 formed on the weaving machine 1

The light emitting part 3 and the light receiving part 4 are formed on both sides of the weaving machine 1 in which the present invention is installed, and the light emitting part 3 attaches the laser module case 5 to the fixing case 6 with a bolt 7 and In the fixed by the spring (7a), an arbitrary conduit (5b) is formed in the front portion (5a) of the laser module case (5) so that the laser beam from the laser module (8) can be transmitted, but the diameter of the conduit (5b) Is Ø0.4-0.8mm and the length is 1-2mm, and the diameter of the conduit 9b is Ø0.4-0.8mm at the front part 9a of the light receiving part case 9 of the light receiving part 4, The length is 0.2-0.6mm. Generally, the wavelength of semiconductor laser is 655nm, which has two big characteristics, straightness and wavelength.

For reference, the wavelength of a semiconductor laser has an error of + -10 nm.

In this paper, when the light is emitted at a certain distance (about 5m-6m) by using the characteristics of the semiconductor laser, the cross section of the light forms a stable energy distribution of Ø10-12mm in the form of '○'. Considering the vibration width of the fine vibration, it can be detected by the light receiving part.

In this way, the main fabric is installed on both sides of the weaving machine in the process of passing the yarn strand (2a) in the weaving machine (1). In the part, the laser always diverges and passes in front of it. At this time, the laser emitted from the laser module 8 is emitted through the conduit 5b formed in the front part 5a of the laser module case 5 so that it is constant and stable. The laser beam is emitted and received through the conduit 9b formed on the front portion 9a of the light receiving part case 9, so that it is easily detected that it is correctly trimmed.

Unexplained symbol 10 is a blower that blows the wind behind when the yarn is broken.

In this paper, since a certain laser is formed, it is easy to detect that the thread is accurately trimmed, and even finely irregular thread can be detected, which is accurate and can reduce the cost.
