specific Embodiment 1

[0081] 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.

[0082] 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 an empty yarn spool detection device and an implement method thereof. The empty yarn spool detection device comprises a truss robot device, and an industrial camera is arrangedon the truss robot for image collection. The empty yarn spool detection device is composed of the truss robot, the industrial camera and an upper computer of a workstation. The empty yarn spool detection device realizes empty yarn spool identification and positioning and the yarn breakage detection (the lack of yarn in a blast pipe indicates that the yarn is broken; and if the situation is not found in time, a great impact is generated.), has a simple structure, reliable operation and controllable cost, and is suitable for promotion in an automatic generation workshop. The industrial camera takes images of an empty spool and yarn connection, and uses the image processing technology to detect the yarn thickness on the yarn spool and whether the yarn exists in a blast pipe mouth or not. Thespace positioning is carried out by the operation of the truss robot. Thus, the information of changing the position of the yarn spool and the information of yarn breaking are sent to the upper computer, the distinguishing accuracy is high, and the speed is high.

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...
