Description
Technical field
The calutron of weft yarn and one kind are used for this in the weft yarn feeder that the present invention relates to a kind of for stopping loom
The slider of kind device.Particularly, stop device of the invention is specially designed in air-jet loom machine and weaving machine with water spraying
The weft yarn feeder used, and under particularly harsh environmental operating conditions, not only for the high frequency insertion of weft yarn but also for powder
Dustiness dye design, dust always exists with higher rate in weaving environment.
Background technique
It is well known that weft yarn feeder is the weft yarn feeder for continuously accumulating weft yarn with a sequence of circle on drum, with
The weft yarn deposit being easy to get by extraction in axial direction is generated during the operation of weft yarn insertion.Electromagnetism of the invention
Weft yarn stop device is located at the outlet side of the weft yarn feeder, so that once the desired amount of weft yarn (passes through what is left from drum
The number of turns measures) pulled out by weft yarn feeder, just weft yarn is prevented to unwind from drum, and weft yarn be inserted into along race and with
Weft yarn is kept to be prevented from always from the unwinding on drum during the operation completion for closing race afterwards.
Above-mentioned stop device generally includes the electromagnetic coil of the movement of control slider, when slider is by inserting its own
Enter in corresponding hole and when passing through the surface for the drum for being wound with weft yarn thereon, the free end of slider prevents other circles from drum itself
Upper unwinding.Therefore, the electromagnetic coil used in this type of device is easy to provide the bistable state of slider, that is, sliding
Device be between retracted mode and forward facing position it is controllable, in retracted mode, weft yarn is fed, the weft yarn in forward facing position
It is kept on the drum for being locked in weft yarn feeder.
The degeneration of weft yarn is avoided in order to ensure enough wearabilities and simultaneously, it is known that is mentioned with suitable ceramic material
For the free end (hereinafter also referred to as end pieces) of slider.Naturally, slider must also include the magnetic field formed to coil
The core of sensitive ferromagnetic material, and executed now by the matrix of thermoset plastic material between both different materials
Connection；Specifically, the molding work that the slider for the device being currently known passes through the thermoset plastic material under molten condition
Skill obtains, and wherein ceramic material end pieces and ferromagnetic core are placed in advance in mold as insert, then passes through cured plastics
Matrix becomes mutually one.
The standard construction of such known slider Cn is shown in Fig. 2, wherein can clearly identify：In circle
The ferromagnetic core F of cylindrical liner shape, in the central peripheral part of slider Cn；The ceramics of first end as slider Cn
Material end component P axially prolongs on the inside of core F with general cylindrical shape and in the aforesaid central portion of slider
It stretches, the annular groove or recess of a series of adherency for being conducive to plastic material matrix M is provided on the inside of core F；Plastic material base
The central part of body M from slider Cn are axially extending along the direction opposite with end pieces P, to form the second end of slider
Portion, matrix M occupy the intermediate annular space between ferromagnetic core F and end pieces P in central portion.Plastic material is used for base
Body M also has the purpose for mitigating slider Cn as far as possible, to reduce its inertia, and thus allows it with high-frequency weft yarn
It is used in the loom of insertion.
Above-mentioned slider is contained in inside the cylinder guide bushings made of plastic material and is axially located online
It encloses on the inside of shell, there is minimum necessary to allowing the movement between the ferromagnetic core F and cylindrical guide bushings of slider Cn
Gap.
Have the shortcomings that some typical cases, this and they using the known weft yarn stop device of the slider Cn of the above-mentioned type
Construction and using feature it is closely related, will now be briefly described these disadvantages.
First the disadvantage is that the abrasion that the cylindrical guide bushings about slider are subjected to.In this regard, it should
It is noted that slider is only by the magnetic field formed by coil when slider is advanced in the alternate path controlled by coil
Attraction/repulsive force of application, these power have centre symmetry relative to the axis of slider, and therefore, these power itself are protected
Slider is held to be centered in completely in the guide bushings of slider.However, when the end pieces P of slider plays its function for preventing weft yarn
When energy, for slider also by cross force, this cross force is when weft yarn is fully stretched in entire race, by being obstructed suddenly
Weft yarn be applied on slider.Although this power is relatively low, it is present in position (i.e. the free ends of end pieces) and anti-
High arm between position (i.e. contact area between core F and corresponding guide bushings) causes to be discharged into the guide bushings
Power is sufficiently high, in weft yarn stop position, guide bushings wall is caused to gradually wear out as time goes by.This causes slider phase
For the movement gradually misalignment of theoretic axial operation line, also, most of all, cause the formation of plastic material dust,
And it gradually pollutes end pieces and is eventually transferred into weft yarn, cause weft yarn dirty and cause possible defect on the fabric.
Second of traditional stop device is the disadvantage is that service life is extremely short in especially heavy application.Also due to end
Inherent vulnerability of the ceramic material of component relative to bending stress, the gradually misalignment of slider Cn may cause to be stopped in weft yarn
Period, end pieces were in certain frequency when end pieces bear the power with the non axial component with the essence that can not ignore
It is broken under rate.
The third disadvantage of service using life is reduced eventually by the special dress of plastic material matrix M and known slider
Match system is associated, and matrix M obviously has lower than being each integrated ferromagnetic material and ceramic material by matrix M
More mechanical resistance properties.Therefore, after undergoing repeated stock at each end stop of its alternating movement in end pieces P,
Including the plastic material volume between end pieces P and ferromagnetic core F by shearing force, therefore gradually show structural failure,
Its elastic property is lost, until end pieces P is caused to be kept completely separate from the plastic material matrix M of surrounding and with retrolisthesis, to make
Equipment is not available.
Therefore, root problem of the invention is to provide a kind of for stopping the calutron of the above-mentioned type of weft yarn,
With significant extended useful service life.Preferably, furthermore useful service life should be able to be based on normal wear mark
Standard is readily determined in advance, because it is no longer by the structural failure-of phenomenon-slider Cn misalignment and plastic material matrix M
It determines, the evolving speed that these phenomenons trend proves an abortion is difficult prediction.
In order to solve this problem, the first purpose of this invention is to improve the composite construction of slider, especially with respect to
Space including the plastic material matrix M between end pieces P and ferromagnetic core F.
Second object of the present invention, which also resides in, improves slider guidance system, more effectively to offset the weft yarn by stretching
The cross force of application, these cross forces cause slider to slide the abrasion of guide member and gradually misalignment due to it.
Other objects of the present invention are finally the negative effects for reducing end stop collision to the structural integrity of slider,
And it reduces dust to be formed, and then protects space locating for slider guide member and further decrease abrasion to slider guide member
The influence of itself.
Summary of the invention
