Description
Technical field
The present invention relates to a kind of for weft yarn being incorporated into the calutron in sheet shuttle-type loom.
Background technology
As is known, projectile shuttle (projectile) loom is with other type of loom not
Being that weft yarn is incorporated in shed open by projectile shuttle with part, described projectile shuttle is has suitable quality
With the cone-shaped metal body of shape, this cone-shaped metal body holds the end of weft yarn.
In shed open exit (referring generally to the position of weaver, corresponding to the right-hand side of loom),
The speed being made projectile shuttle by brake unit is reduced and makes it stop, and weft yarn is released and therefore
Projectile shuttle is made to be returned towards the input side (generally at left-hand side) of loom by suitable continuous transmission system
Return.Throwing in side, the projectile shuttle of single entrance is loaded onto and it progressively takes to release platform front
Device on, at release platform, described projectile shuttle is rendered in shed open again, thus will be another
One weft yarn is brought into wherein.
Although this kind of loom have especially weave non-constant width fabric in terms of visible advantage, its
There are some notable defects.Firstly, there are mechanicalness defect, this kind of defect with must be applied to
The high impulse thrust of projectile shuttle is the most relevant.Especially, execute by input component except what projectile shuttle was subject to
Outside problem determined by the impulse force added, there is also design one produce sufficiently strong but only
The complexity of the suitable mechanism of big thrust.
GB2.003.198 discloses a kind of traditional delivery device, is wherein intended to abut securely
Component of throwing on projectile shuttle rear end is supported on the action bars driven by torque arm, described torsion
Power bar passes through cam mechanism CYCLIC LOADING.
As can easily guess, just the stress bearing and applying, Yi Ji
For throwing in the chance of the characteristics of motion determined in step and control projectile shuttle, cam is utilized to load
The system of torque arm is more crucial mechanical part.
It practice, owing to projectile shuttle is launched by shed open with the highest pulse acceleration, and
Projectile shuttle is not controlled by any drive member, so occurring that in gripper shuttle loom some are typical
Braiding problem, especially weft yarn have high primary stress and the projectile shuttle whole stroke along shed open
There is the most uncontrolled traveling situation.Especially, the most completely symmetrically send out when thrust pulse
When life is on projectile shuttle, projectile shuttle track is by lateral vibration, and this lateral vibration is slided wherein by projectile shuttle
Dynamic guiding piece controls, but this efficiency making input and systematicness are deteriorated.
The JP-48-44559 (1973) of Mitsubishi Electric (Mitsubishi Electric) discloses
A kind of feasible alternative solution thrown in for projectile shuttle, wherein projectile shuttle is no longer because of mechanical thrust structure
Part reaches maximum setting and throws in speed, but produces at sheet because projectile shuttle is immersed in electromagnetic field therein
Acceleration on shuttle and reach maximum setting and throw in speed.Especially, described electromagnetic field by along
One or two coils that projectile shuttle track is sequentially arranged produce, and described track is in coil
Portion's axial cavity, in order to produce average and parallel magnetic field around this track.
Although the existing many decades of understanding to above-mentioned input technology up to now, but up to now
Never by this input Technical investment to actual application.At " the Using that publishes an article
Electromagnetic force in weft insertion of a loop " (it is loaded in Fibres&
Textiles in Eastern Europe-2005 July/JIUYUE, Vol.13, No.3 (51)-
The 67-70 page) in comprise the first generation weft yarn electromagnetism to the above-mentioned type introduce system detailed
Comment and analysis, wherein, author S.A.Mirjalili set forth spinning at Yazd university (Iranian)
Knit that engineering department is carried out, carry out accurately for projectile shuttle ferromagnetic material made by calutron
The result of the research thrown in.
In this is published an article, be discussed in detail when projectile shuttle arrive coil center position and
Therefore by when starting to be affected by the braking action applied by the second half parts of coil, it is necessary to
Cut off the confession induced current of the coil of electromagnetism delivery device.If it practice, current stabilization ground keeps
In coil, then the stable equilibrium position of projectile shuttle will correspond exactly to the center of coil,
In this position, projectile shuttle will stop after carrying out a series of fast vibration around this center.
Based on this discovery, and on the other hand in order to realize the required rate of departure of projectile shuttle with
Good compromise between the good service efficiency of the action of a magnetic field, the authors suggested that the length of projectile shuttle is equal to
The 75% to 125% of the length of coil.
But, the studies above is at last it is pointed out that utilize this delivery device can not realize with machinery and throw
The projectile shuttle speed that the speed of the projectile shuttle put is suitable.
The open DE-10 2,009 019935 of patent of Konrad Hilmar discloses finally
The Weft inserting device of a kind of renewal using electromagnetic force, this Weft inserting device includes being provided with single projectile shuttle
Loom, described single projectile shuttle is similar because being arranged at two opposed ends of shed open two
Calutron and be alternately sent in shed open, each of which in described calutron is by four
The individual coil that adjoins is constituted.Based on the letter relevant to the angular coordinate of the main motion of projectile shuttle speed and loom
Breath, microcontroller activates described coil continuously, in order to accelerates or correspondingly brakes projectile shuttle.Not yet
Have a mode that detailed disclosure generation coil activates, but under any circumstance it is readily apparent that
The activation of coil is with before projectile shuttle and then one after the other occurring.
In above-mentioned patent is open, with no specific disclosure of the ratio between projectile shuttle length and loop length
Rate, but it is readily apparent that this ratio is in above-mentioned Mirjalili institute public affairs from accompanying drawing
The upper value of the scope opened.
But, in actual applications, the solution that above-mentioned prior art is proposed the most not to
Go out gratifying result.It practice, the Mitsubishi schematically shown in FIG solves
The biggest defect of scheme is, only the smaller range of the relative position P between projectile shuttle and coil
Captivation F that interior applying is big.Although coil is more much larger than the longitudinal size of projectile shuttle, however available
The most very limited in the space accelerated, and in view of the required last input speed of projectile shuttle,
This means the highest acceleration and power.This acceleration and power need to use high electric current, and
And cause the significant losses caused because of the Joule effect in coil and therefore cause jettison system to have
Having low-down whole efficiency, whole efficiency refers to the kinetic energy of projectile shuttle/for throwing in the electricity of projectile shuttle
Energy.Therefore, this solution there is also serious coil cooling problem, additionally occur
The problem that weft yarn has the biggest mechanical stress.
Any further loop elongation schematically shown in fig. 2 in any situation the most not
This situation can be improved, this is because once projectile shuttle itself is completely in coil, because of the most
Through the reason of statement, electromagnetic force F being applied on projectile shuttle will be zero.Therefore, at Free Region
In electromagnetic force equal in the case of, due to for projectile shuttle accelerate purpose invalid all other
Joule effect in coil section, will produce bigger consumption.
Finally, in Hilmar solution, propose to increase number of coils and simultaneously by line
The longitudinal size of circle is reduced to be significantly less than the value of projectile shuttle length, in order to limit because Joule effect is made
The loss become and the efficiency therefore improving system.But, the coil of this moderate-length execute
The electromagnetic force added is the lowest, even and if the efficiency of each single coil be above previously solving
The efficiency of the coil of scheme, from the point of view of current commercial Application, still can not be successfully by sheet
Shuttle accelerates to required speed.
Summary of the invention
Therefore, it is an object of the invention to the introducing for weft yarn proposing in a kind of gripper shuttle loom
Calutron, this calutron do not exist drawbacks described above and therefore allow as required along
Longitudinal region applies high electromagnetic force to projectile shuttle, in order to realize the required final speed of projectile shuttle, simultaneously
The system that do not produces has a low electrical efficiency and weft yarn has the drawbacks described above of excessive mechanical strain.
By having the electromagnetism wefting insertion in the gripper shuttle loom of the feature that independent claims 1 are limited
Device realizes this purpose.Other defining this Weft inserting device in the dependent claims is preferred

The electromagnetism Weft inserting device disclosed in Mitsubishi and Hilmar of the coil of elongation further.
In order to simplify further, accompanying drawing illustrate only the positive component of power F, this is because such as exist
As described in Mirjalili document, it is clear that exceed the center relative to coil at projectile shuttle
In traveling behind position, if not cutting off the supply of electric power of coil, then symbol will be produced contrary
But the electromagnetic force that trend is identical.
In the bottom of Fig. 1, projectile shuttle 1 is illustrated at the holding fix in coil 2 front.When swashing
During hot line circle, coil produces the electromagnetism changed according to projectile shuttle position P subsequently on projectile shuttle
Power F (such as schematically show on the top of Fig. 1), the change of electromagnetic force relates to from starting position
Arrive to projectile shuttle tip and enter quickly the increasing of position in region corresponding to coil, be one section subsequently
Maximum in relatively limited scope and the most unexpected being decreased until when projectile shuttle tip is positioned at
Coil 2 revert to zero when leaving areas adjacent.
As being described above, when when publishing an article of S.A.Mirjalili of comment,
This coil arrangement scheme thus the limited range of only relative position between projectile shuttle and coil
Captivation interior, that the most only permission applying is the biggest in the Part I of loop length.
This situation results in the notable defect having been described above.
The coil 2 with larger lengths as shown in Figure 2 is used not change above-mentioned electromagnetic force F bent
Line raises and the shape in peak-peak part initial, but has only elongated the falling portion of curve
Point, in this region, electromagnetic force still has the least value and is finally zero (when projectile shuttle is complete
When being entirely positioned at coil)；Therefore, this solution can cause the big worsening degree of system effectiveness.
On the contrary, as update Hilmar document in propose and as shown in Figure 3,
Use there is the coil of short length or a series of coil 2 although to guarantee that device has bigger
Efficiency, but can proportionally reduce the peak-peak of electromagnetic force F, therefore not in can
The required input of projectile shuttle 1 is reached in the relatively limited space of the airborne this kind of device of loom
