Abstract
The utility model discloses a roving degree of consistency on -line measuring device belongs to weaving technical field, detection device includes the special unit of low -cost CMOS looks machine, LED the light source device and image processing for acquire the roving image, it installs on mobile rail just perpendicularly with the roving to examine the gauge head unit, the guide rail is fixed on the fly frame board, examines the gauge head unit and is in can go the rounds on the guide rail to remove, the roving degree of consistency is differentiated according to the quantitative change of roving in real time on line to the special unit of image processing.
Description
Technical field
This utility model is specifically related to a kind of rove uniformity on-line measuring device, belongs to textile technology field.
Background technology
Roving Frames is the preparatory process before coarse yarn and spinning fine yarn.Its main task is to share the partial draft from drafting to spun yarn, applies the suitable twist and by reeling roving on bobbin to rove, forms the flyer bobbin that winding shaping is good, adapts to the needs feeding and unwinding on spinning frame, improves the quality of spun yarn.
The tester of existing test rove bar evenness has many defects, the most matching used test stand, as condenser type Uster sliver evenness tester strip test stand and rove test stand are divided into two kinds, both are the most general, therefore changed into testing rove or being changed into the test strip period of the day from 11 p.m. to 1 a.m by test rove changing test stand by test strip, add workload；And test stand volume is big, Heavy Weight, inconvenient operation；The test stand creel main shaft of domestic same type is longer, slightly collides yielding, eccentric, affects measuring accuracy.
And the method for above-mentioned test rove bar evenness is all off-line test, it is impossible to the rove uniformity is carried out the most real-time detection, this is easy for occurring once to go wrong, then can not find in time, and then the problem causing greater loss for producer.
Utility model content
The purpose of this utility model is: the problem existed for above-mentioned prior art, a kind of rove uniformity on-line measuring device is proposed, this device arranges image detection device during forming package by rove on fly frame and realizes the on-line checking of the rove uniformity, utilize the change of the online uniformity of image processing techniques measurement rove, realize roving yarn quality automatically to detect and on-line checking, thus lay the foundation for improving the yarn quality of follow-up spun yarn.
Technical solutions of the utility model are as follows: this utility model one fly frame rove uniformity on-line measuring device, it is characterised in that include that at least one detects head unit；Described detection head unit includes low cost CMOS camera apparatus and LED light source device, obtains rove image for online；Described detection head unit is arranged on guide rail and angled for vertical acquisition rove image, and can carry out touring movement,
Further, described detection head unit is by camera and image procossing special cell, enlarging lens and LED light source composition.
Further, described guide rail is fixed on fly frame board；
Further, described detection head unit distance rove 1-40cm.
Further, described camera is low cost CMOS camera, cheap, and resolution is 640 × 480 pixels, and frame frequency is 25fps；Described image procossing special cell is integration block device, for being processed by the image of collection, extracts rove diameter data, and is analyzed data and processes, and the rove of unusual condition occurs in monitoring；Described enlarging lens is 1-6 times and amplifies；Described LED light source is fixed on the front end of enlarging lens, and the acquisition for rove image provides illumination.
Further, after described enlarging lens is installed, its focus is near rove section, less than in the scope with the rove section axle center circle for the center of circle with 3cm as radius.
Further, described rove uniformity detection control includes parameter setting apparatus, data exception alarm lamp, result of calculation display module and image processing circuit plate；Described parameter setting apparatus, data exception alarm lamp, result of calculation display module are connected with image procossing special cell circuit board respectively.
Further, cam device uses face battle array CMOS chip, in image acquisition process, close the automatic white balance function of CMOS, and the value of white balance is set as 0.6, coordinate with corresponding image background light source, time of exposure is set as 1/40ms, and shooting speed is 25fps, to prevent Hz noise.
The open a kind of fly frame rove uniformity on-line measuring device of this utility model, the on-line checking of the rove uniformity is realized by arranging image detection device during carrying out package at formation rove, this utility model uses image detection device, pass through image analysis technology, can realize automatically detecting and on-line checking, thus lay the foundation for Automated condtrol.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.

Detailed description of the invention
Fig. 1 and Fig. 2 is respectively installation site structural representation sketch on fly frame, the structural representation of New Image detection head unit.As shown in Figure 1, 2, by the rove yarn formed after the draw zone drawing-off formed the rear roller of fly frame board 8 to front roller, after being exported by front roller 1, by guide eyelit 3, then the coiler device having rail 6 and flier 4 to constitute forms Rove Package.By camera and graphics processing unit 9, enlarging lens 10, LED light source 11 composition diagram picture detection head, this detection head is arranged on touring movement on guide rail 2, when moving to setting position every time, pause 20s, distance rove 10cm also becomes vertical with rove, the thickness of the rove on detection fly frame, enlarging lens is 2 times of amplifications.
