Abstract
The utility model discloses a yarn tension detection device on knitting machine is the application of a new technology in tension is measured, and the biggest advantage of this method need not contact the yarn, to not wearing and tearing of yarn, does not also apply extra tension to and the sth. Made by twisting is not twisted or moved back to the yarn. The utility model discloses a beam of a loom, yarn, back beam, optical emitter, prism, imaging lens, charge coupled device CCD, video processor, microcomputer constitute, the optical emitter is in normal bright state, the projection that the optical emitter caused the yarn through the prism, measure through imaging lens and weave the thickness change that the yarn took place in the engineering, then pass through charge coupled device CCD with its change that converts the electric quantity into, charge coupled device CCD passes through video processor, video processor extrapolates tensile size through microcomputer and then accurate.
Description
Technical field
The utility model relates to a kind of checkout gear, particularly relates to the Yarn tension detection apparatus on a kind of knitting machine.
Background technology
During automatic knitting machine work, the tension force how detecting yarn is one of essential condition affecting knit product quality.At present, yarn tension is measured and is all adopted " W " type pattern pressure sensor device, and it is made up of two fixing thread-carrier rods and a tension rail.Tension rail is placed between two fixing thread-carrier rods, and yarn is successively by fixing thread-carrier rod lower end, tension rail upper end, fixing thread-carrier rod lower end, and yarn is in " W " shape.This device draws yarn tension by measuring yarn through the friction of tension rail.The shortcoming of this device is: use after a period of time, and due to the wearing and tearing of tension rail, and the impurity of yarn itself and rubbish can be attached to tension rail surface, coefficient of friction is caused to become large, the yarn tension detected is uneven, exceeds standard value, thus makes the data that draw inaccurate.
Utility model content
The purpose of this utility model is the deficiency that the Yarn tension detection apparatus in order to overcome on above-mentioned existing knitting machine exists, and provides a kind of novel structure, the Yarn tension detection apparatus on the knitting machine that yarn tension value detection accuracy is high.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: the Yarn tension detection apparatus on a kind of knitting machine, comprises beam of a loom, yarn, the back rest, optical transmitting set, prism, yarn, imaging len, charge coupled device ccd, video processor, microcomputer.Described charge coupled device ccd (ChargeCoupledDevice) is the core devices forming this yarn detection system, ccd image sensor is used in fabrication processes and measures yarn tension, the application of a kind of new technology in tonometry, the great advantage of the method to contact yarn, yarn is not is not worn and torn, extra tension force is not applied yet, and not to Yarn twisting or untwisting.
The operation principle that have employed ccd image sensor yarn tension measuring system due to the Yarn tension detection apparatus on a kind of knitting machine of the utility model measures the thickness change weaving yarn in engineering and occur by optical principle, then be converted into the change of electricity, and then precisely extrapolate the size of tension force by system.
Because ccd sensor is under the condition pre-set, control the suspended span position of acquiescence, cause the tension force can not measuring any position of yarn in practice, so just more reasonably can not regulate the size of yarn tension, this is that it is intrinsic, the shortcoming that cannot correct.
Figure below elaborates to the Yarn tension detection apparatus on a kind of knitting machine of the present utility model by reference to the accompanying drawings.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the Yarn tension detection apparatus on a kind of knitting machine of the utility model.
Reference numeral and corresponding parts title as follows: beam of a loom 1, yarn 2, the back rest 3, optical transmitting set 4, prism 5, imaging len 6, charge coupled device ccd 7, video processor 8, microcomputer 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Yarn tension detection apparatus on a kind of knitting machine as shown in the figure, is formed primarily of beam of a loom 1, yarn 2, the back rest 3, optical transmitting set 4, prism 5, imaging len 6, charge coupled device ccd 7, video processor 8, microcomputer 9.Described optical transmitting set 4 is in normal bright state; The projection that optical transmitting set 4 is caused by prism 5 pairs of yarns 2; Measure by imaging len 6 thickness that in braiding engineering, yarn 2 occurs to change; Then the change of electricity is converted into by charge coupled device ccd 7; Described charge coupled device ccd 7 passes through video processor; Described video processor is by microcomputer and then the size precisely extrapolating tension force.
As mentioned above, the utility model can well be realized.
