Description
Technical field
The invention belongs to technical field of textile machine, more particularly to a kind of cylinder yarn suction nozzle positioner.
Background technology
On automatic winder, with the increase of winding spooler cheese diameter, the relative position that cylinder yarn is contacted with groove drum can occur
Offset, in order to ensure suction nozzle and cylinder yarn relative distance and parallel uniformity, passes through support arm rotating shaft band moving cam and orientation sensing
Device forms a kind of linkage mechanism, ensures the efficiency looked for loose thread success rate, improve machine of cylinder yarn suction nozzle.
Existing cylinder yarn suction nozzle positioner is by using the cam curve track being fixed in support arm rotating shaft to be oriented to, promoting
Be connected sensor mandril, makes to keep accurate linkage contact between each several part, to realize that suction nozzle is permanent all the time with cylinder yarn relative position
It is fixed, principle signal such as Fig. 1.But in gripping support arm structure at rear, since support arm configurations are in space and locating rod location conflicts, no
The positive direct acting mode of cam can be realized, so realizing that suction nozzle and cylinder yarn relative position are constant using reverse cam structure.
In Chinese patent literature, entitled " the cylinder yarn absorption auxiliary system of structure optimization ", Publication No.
The patent of invention of " CN104555602A " discloses a kind of technical solution, including driven push rod one end is tight against cam curved surface, another
End sets suction nozzle alignment sensor, and driven push rod can slide along its length makes cylinder yarn suction nozzle alignment sensor closer or far from cylinder
Yarn suction nozzle, the position for reaching relative ideal between suction nozzle and cylinder yarn face is realized by the improvement to cylinder yarn suction nozzle, rather than to positioning
The improvement of device is realized.
The content of the invention
In order to solve the above technical problem, the present invention provides a kind of cylinder yarn suction nozzle positioner, which has structure
Compact, it is accurate to transmit distance, and the confined space can effectively avoid the interference of locating rod and support arm the advantages of.
The technical scheme is that：
A kind of cylinder yarn suction nozzle positioner, including the support arm of cylinder yarn is gripped, it is described for the locating rod of cylinder yarn suction nozzle positioning
Locating rod is equipped with alignment sensor close to cylinder yarn suction nozzle end, and the other end is movably installed on stent；Further include and turn with the support arm
The positioning swing rod engaging member of axis positioning assembling, the swing link cam that the cylinder with positioning the swing rod engaging member other end is in contact, swing rod
Cam is articulated with stent, its opposite side vertical plane and locating rod end contact, locating rod are ensured convex with swing rod by elastomeric element
The vertical plane contact of wheel.
Compared to the prior art, the design that this programme is moved based on reverse cam curve, devises positioner, and cylinder yarn is straight
Footpath increase, support arm rotating shaft movement, synchronous drive positioning swing rod engaging member action, and then make swing link cam along reverse inter_curve rail
Mark action around centre of gyration swing, promotes locating rod movement by the vertical plane of swing link cam is positive, realizes cylinder yarn suction nozzle
Positioning stop position and support arm winding cylinder yarn cocked position it is synchronous, ensure the uniformity of cylinder yarn suction nozzle and cylinder yarn position spacing
With collimation.For positive cam curve, locating rod center line just can guarantee that gearing well by the centre of gyration of cam
Can, and the necessary very little of point of locating rod contact cam locus, distortionless it could so be walked along track.The technical program
In, force direction is by locating rod center, but locating rod center need not cross cam center, can in confined space staggered positions, and
And the cusp of locating rod contact swing link cam vertical plane is unlikely to undue too small.
Based on such scheme, the present invention is also made that following improvement：
The elastomeric element is the spring being set in the locating rod, and spring is in compressive state.In this improvement project
Under spring force, remain locating rod to be in close contact with swing link cam vertical plane, and force swing link cam curvilinear sides
Oppress always on the cylinder of locating rod engaging member.Swing link cam S-curve track remains and positioning oscillating rod engaging member
Small column be in close contact, in the case where support arm rotates, locating rod and preceding is promoted by the vertical plane synchronous forward of swing link cam
Square sensor actuation, to realize the positioning stop position of cylinder yarn suction nozzle synchronous with support arm cylinder yarn cocked position.
The swing link cam is equipped with curvilinear plane, and positioning swing rod engaging member is coordinated so as to movable pendulum by cylinder and curvilinear plane
Moving cam moves.In this improvement project, it is convex that the centre of gyration of swing link cam is put into by swing rod by the design of curvilinear plane and cylinder
The lower end of wheel, can not depend on the centre of gyration of support arm, in the narrow and small space do not interfered, can position swing rod knot by changing
The different shape of component, is transferred to the arc track of support arm rotating shaft on swing link cam curvilinear plane indirectly, avoids the interference of support arm,
And cylinder contacts cam curve track, wear extent is reduced.
The radius of the cylinder is less than the minimum profile curvature radius of curvilinear plane.In order to ensure curve movement rail in this improvement project
Mark is undistorted, (this sentence can remove, and the track of cam is got according to cylinder yarn change location, it is impossible to and simple is small, if
Column position on swing rod engaging member is changed, equivalent to the radius change turned round around the shaft, at this moment cam locus can phase
That answers changes) radius of cylinder is the smaller the better.
The positioning swing rod engaging member is assembled by flat hole and support arm rotating shaft positioning.Pass through the processing in hole in this improvement project
The positioning assembling of flat horizontal surface and support arm rotating shaft, to ensure cylinder yarn bare bobbin initial makeup location, it is not necessary to adjusted by positioning pin
Assembling.
The leg extremities have to the interference part of locating rod direction protrusion.The technical program is in order in the confined space
The interference of locating rod and support arm is avoided, whether support arm has interference part, the protrusion direction of interference part according to the specific sky in equipment
Between depending on.Further include the side stand of load support, side stand be fixedly mounted with rack cabinet.
