Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as figure 2 As shown, it is a schematic diagram of an embodiment of the yarn withdrawal control system of the weft precessor of the present invention. The system can be directly applied to the existing weft storage device, and can complete the yarn withdrawal control together with the yarn withdrawal photoelectric weft detector 30 . The yarn withdrawal control system in this embodiment includes a yarn withdrawal self-learning unit 21, a photoelectric cell control unit 22, and a yarn retaining needle control unit 23. It can be integrated into the main control board of the existing weft...

Abstract

The invention provides a yarn-withdrawing control system and method for a weft storage device. The yarn-withdrawing control system comprises a yarn-withdrawing self-learning unit, a photoelectric-tube control unit and a yarn-stopping-needle control unit, wherein the yarn-withdrawing self-learning unit is used for recording the yarn-withdrawing recording period from the time when a yarn stopping needle is lifted to the time when the yarn stopping needle falls down as the output pulse of a yarn-withdrawing photoelectric weft feeler reaches a preset value, and is used for calculating yarn-withdrawing control time according to the yarn-withdrawing recording time; the photoelectric-tube control unit is used for closing a luminescent tube of the yarn-withdrawing photoelectric weft feeler after the yarn-withdrawing control time is obtained; the yarn-stopping-needle control unit is used for allowing a timer to start to time when the yarn stopping needle is lifted and after the luminescent tube of the yarn-withdrawing photoelectric weft feeler is closed and allowing the yarn stopping needle to fall down when the timer reaches the yarn-withdrawing control time.

Description

technical field [0001] The invention relates to a weft feeder of a loom, and more specifically, to a yarn withdrawal control system and method for the weft feeder. Background technique [0002] The weft feeder is an indispensable device in air-jet looms, water-jet looms, rapier looms and other equipment. It is mainly used to store a certain number of turns of yarn on the hub of the weft feeder, and in each weaving cycle According to the width of the loom, the yarn of the set number of turns is released during the weft insertion action. [0003] There is an important device in the weft feeder, that is, the yarn unwinding photoelectric weft detector, whose main function is to help release the yarn with the set number of turns accurately. Such as figure 1 As shown, it is a schematic diagram of the functional modules and signal transmission of the main control board 10 of the weft feeder. When the main control board 10 of the weft feeder is running on the express train of the...
