Description
Technical field
The present invention relates to a kind of Weaving device, especially a kind of cored silk broken thread detector.
Background technology
In the production process of cored silk, often there is the situation of fracture of wire, low with artificial checking efficiency, there is serious undetected situation, have impact on the quality of cored silk finished product.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cored silk broken thread detector, can solve the deficiencies in the prior art, and can realize automatic detection and the equipment automatic train stop of fracture of wire, reliability is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of cored silk broken thread detector, comprise driven delivery wheel and active delivery wheel, degree of tension regulating control and thread break detector is provided with between driven delivery wheel and active delivery wheel, initiatively delivery wheel is connected with motor by driver, degree of tension regulating control comprises symmetrically arranged two rubber friction discs, the first spring is provided with between two rubber friction discs, two rubber friction disc arranged outside have hydraulic pressure buckle, thread break detector comprises the mechanical detector and visual detector that are arranged in series, mechanical detector comprises micro-switch, micro-switch is connected with supporting arc arm, the top of supporting arc arm is provided with pulley, visual detector comprises annular light source, the centre of annular light source is provided with CCD camera lens, the offside of annular light source is symmetrically arranged with two pieces of reflectors, driver comprises rotating plate and driven disc, rotating plate is connected with motor, rotating plate is provided with link slot, driven disc is connected with hydraulically extensible bar, driven disc is provided with the contiguous block matched with link slot, the second spring is provided with between contiguous block and driven disc, also comprise a controller, the input end of controller is connected to micro-switch, CCD camera lens respectively, and the mouth of controller is connected to hydraulic pressure buckle and hydraulically extensible bar respectively.
As preferably, described driven delivery wheel, the initiatively surface of delivery wheel and pulley are provided with polytetrafluoroethylene protective cover.
As preferably, described reflector and incident light are 45 ° of angles.
The beneficial effect adopting technique scheme to bring is: cored silk is sent to initiatively delivery wheel from driven delivery wheel through degree of tension regulating control and thread break detector.Rubber friction disc provides friction force to cored silk, by regulating hydraulic pressure buckle, can change the tensile force of cored silk.Pulley is overlapped on cored silk, if there is fracture of wire, trigger micro-switch, active delivery wheel is separated with motor by controller hydraulic control expansion link.While mechanical detection, the present invention also carries out vision-based detection simultaneously, is accepted by the reflection of annular light source, CCD camera lens can be clear obtain the image of cored silk, judged the situation of fracture of wire by controller.Apply while two kinds of detection modes, loss can be reduced to less than 0.2%.Polytetrafluoroethylene protective cover friction coefficient is low, can play the effect of protection cored silk.Reflector and incident light are 45 ° of angles, at utmost can reduce the irregularity of light source, improve vision-based detection effect.

Detailed description of the invention
With reference to Fig. 1, the present embodiment comprises driven delivery wheel 1 and active delivery wheel 2, degree of tension regulating control and thread break detector is provided with between driven delivery wheel 1 and active delivery wheel 2, initiatively delivery wheel 2 is connected with motor 3 by driver, degree of tension regulating control comprises symmetrically arranged two rubber friction discs 4, the first spring 5 is provided with between two rubber friction discs 4, two rubber friction disc 4 arranged outside have hydraulic pressure buckle 6, thread break detector comprises the mechanical detector and visual detector that are arranged in series, mechanical detector comprises micro-switch 7, micro-switch 7 is connected with supporting arc arm 8, the top of supporting arc arm 8 is provided with pulley 9, visual detector comprises annular light source 10, the centre of annular light source 10 is provided with CCD camera lens 11, the offside of annular light source 10 is symmetrically arranged with two pieces of reflectors 12, driver comprises rotating plate 13 and driven disc 14, rotating plate 13 is connected with motor 3, rotating plate 13 is provided with link slot 15, driven disc 14 is connected with hydraulically extensible bar 16, driven disc 14 is provided with the contiguous block 18 matched with link slot 15, the second spring 19 is provided with between contiguous block 18 and driven disc 14, also comprise a controller 17, the input end of controller 17 is connected to micro-switch 7, CCD camera lens 11 respectively, and the mouth of controller 17 is connected to hydraulic pressure buckle 6 and hydraulically extensible bar 16 respectively.Often organize cored silk 21 and can reach 400 threads.
It should be noted that described driven delivery wheel 1, the initiatively surface of delivery wheel 2 and pulley 9 are provided with polytetrafluoroethylene protective cover 20.
In addition, described reflector 12 is 45 ° of angles with incident light, and controller 16 adopts the S7-200 series Programmable logic Controller (PLC) of Siemens Company.
Principle of work of the present invention is: cored silk 21 is sent to initiatively delivery wheel 2 from driven delivery wheel 1 through degree of tension regulating control and thread break detector.Rubber friction disc 4 pairs of cored silks 21 provide friction force, by regulating hydraulic pressure buckle 6, can change the tensile force of cored silk 21.Pulley 9 is overlapped on cored silk 21, if there is fracture of wire, trigger micro-switch 7, active delivery wheel 2 is separated with motor 3 by controller 17 hydraulic control expansion link 16.While mechanical detection, the present invention also carries out vision-based detection simultaneously, is accepted by the reflection of annular light source 10, CCD camera lens 11 can be clear obtain the image of cored silk 21, judged the situation of fracture of wire by controller 17.Apply while two kinds of detection modes, loss can be reduced to less than 0.2%.Polytetrafluoroethylene protective cover 20 friction coefficient is low, can play the effect of protection cored silk 21.Reflector 12 and incident light are 45 ° of angles, at utmost can reduce the irregularity of light source, improve vision-based detection effect.
