Problems solved by technology

[0002] At present, there is no automatic detection and replacement system for empty yarn cans of textile machines, and most of them are manually replaced.
The manual replacement method requires someone to be on duty. The yarn reels in the textile workshop are replaced by a large amount and the working hours are long. Often, the replacement is not timely and the inspection is missed, which reduces the production efficiency.
[0003] With the development of machine vision technology, the degree of automation and intelligence in the textile industry is also increasing, and there is currently no solution for the detection and replacement of empty yarn barrels

specific Embodiment 1

[0080] Such as figure 1 As shown, the yarn empty cylinder detection device is composed of eight-hole air-feeding yarn rack, binocular vision module, sliding guide rail, truss robot, wireless communication module, PC upper computer, display module, etc.

[0081] In the overall device, the upper computer assigns numbers to all eight-hole air-feeding creels No. 1, No. 2, No. 3, ..., and No. 9 (the specific number of eight-hole air-feeding creels can be specified according to actual working conditions). The yarn bobbins of each yarn delivery frame are divided into A and B columns, and the yarn bobbins of each column are numbered in Arabic numerals from top to bottom. Example: 1A1 means the first bobbin bar of the A column of No. 1 eight-hole air-feeding creel, and 3B7 means the seventh bobbin bar of the B-pillar of No. 3 eight-hole air-feeding creel. When an empty can is detected, the number is converted into a hexadecimal code and sent to the can changing robot for coordinate po...

Abstract

The invention discloses a yarn empty cylinder detection device and a realization method thereof, which comprise a truss robot device, and an industrial camera is installed on the truss robot to collect images. The present invention is composed of a truss robot, an industrial camera and a workstation host computer, and realizes the identification and positioning of the empty barrel of the yarn barrel, and the detection of whether the yarn is broken or not (the absence of yarn in the air duct indicates that the yarn is broken, if it cannot be found in time, Great impact), simple structure, reliable operation, controllable cost, suitable for promotion in automated production workshops; industrial cameras take pictures of empty barrels and yarn connection images, and use image processing technology to detect yarn thickness on yarn bobbins And the detection of whether there is yarn at the mouth of the air duct, the spatial positioning is carried out through the operation of the truss robot, and based on this, the position of the replacement yarn tube and the yarn breakage information are sent to the upper computer, and the judgment accuracy is high and the speed is fast.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a yarn empty tube detection device and method. Background technique [0002] At present, there is no automatic detection and replacement system for empty yarn cans of textile machines, and most of them are replaced manually. The manual replacement method requires someone to be on duty. The yarn bobbin replacement in the textile workshop is large and the working hours are long. Often, the replacement is not timely and the inspection is missed, which reduces the production efficiency. [0003] With the development of machine vision technology, the degree of automation and intelligence in the textile industry is also increasing, and there is currently no solution for the detection and replacement of empty yarn barrels. Contents of the invention [0004] According to the above-mentioned deficiencies in the prior art, the present invention provides an online detection device for empty barre...
