Photoelectric positioning system reeded by reeding machine

Abstract

The invention discloses a photoelectric positioning system reeded by a reeding machine. The system comprises a light emitting diode, a photoelectric detection device and a micro processing unit, wherein the light emitted by the light emitting diode is incident on a reeding plate so as to obtain an optical signal relevant with physical distribution of a dent reeding gap; the photoelectric detection device is used for performing photoelectric detection on the optical signal and outputting a corresponding electrical signal; the micro processing unit is used for detecting the physical distribution of the dent reeding gap according to the electrical signal and sending an adapted operation instruction to a stepper motor and a reeding device; and the reeding device finishes reeding operation or continuously moves according to the operation instruction of the micro processing unit. The photoelectric positioning system is simple in structure and principle, low in cost, convenient to use and widely applied to various automatic reeding machines.

Description

Technical field [0001] The invention belongs to the technical field of textiles, in particular to a reed piercing system of a reed piercing machine, in particular to a photoelectric positioning system of the reed piercing machine. [0002] Background technique [0003] With economic globalization and the continuous acceleration of the process of transforming traditional industries with high-tech science and technology, the competition in the textile industry is increasing. This is not only a new opportunity and a new challenge for my country's textile industry, but also the key for China to build a textile power from a major textile country. Accelerating scientific and technological progress is not only an inherent requirement for China's textile industry to respond to new opportunities and challenges, but also an objective need for my country to build a well-off society in an all-round way and basically realize the country’s industrialization by 2020. The fundamental factor of bu...

Problems solved by technology

When the density of reed teeth increases, the distance between reeds will be greatly reduced. For example, the gap spacing of high-density reed boards with 52 teeth / cm is not more than 10 μm, and the existing equipment is difficult to adapt

For example, the efficiency of manual reeding is quite low, while the electromagnetic reeding will cause great damage to the reed board, the positioning accuracy and density cannot meet the requirements, and it is not conducive to intelligent control

Other typical problems include: yarn penetration at small spacing; determination of reed gap center; reed gap determination when yarn is entangled; slight bending deformation of reed board during use; reed tooth adhesion; tooth missing determination and repeat or skip reed teeth etc.
