Special infrared reflection type yarn guide device for yarn breakage monitoring

Abstract

The invention discloses a special infrared reflection type yarn guide device for yarn breakage monitoring. The special infrared reflection type yarn guide device is characterized in that the upper lateral side, the lower lateral side and the periphery of a spinning frame yarn guide plate are provided with an infrared reflection type monitoring device respectively; the continuity of yarn production in the process of spun yarn spinning is sensed by every monitoring device, the intensity of a reflected light analog signal is converted into a digital signal, and the analysis is performed on the output digital signal so as to determine whether spun yarns of a ring spinning frame are broke yarns or not; the judgment on the yarn breakage of the spinning frame is based on whether the digital signal is produced or not within a certain period of time, the spun yarns are not broken if yes, and the spun yarns are broken otherwise. The special infrared reflection type yarn guide device for the yarn breakage monitoring is simple in structure, free of special requirement for raw materials and the yarn variety and applicable to the yarn breakage monitoring of the ring spinning of cotton spinning, wool spinning and color spinning and the like.

Description

technical field

[0001] The present invention belongs to the field of textile technology, and relates to the monitoring technology for spinning ring-flipped yarns, in particular to the method of judging whether the yarn is broken by using the difference in the intensity of reflected light on the surface of the yarn and the intensity of the reflected light when there is no yarn. Monitoring special yarn guide device. Background technique

[0002] as attached figure 1 As shown in the schematic diagram of the existing yarn guide plate of the spinning frame, the fiber bundles output from the front roller triangle area of ​​the spinning frame pass through the yarn guide hooks on the yarn guide plate, twist to form yarn, and finally wind up on the bobbin. In this process, due to the presence of tension inside the yarn, and insufficient strength of the yarn itself, the spun yarn will eventually break. Checking and handling broken yarns is one of the work tasks of the spun yarn stop...
