Description

The loom electromagnetism selects the latitude actuating unit

Technical field:

The utility model relates to a kind of loom weft selector.

Background technology:

The various shuttleless looms (comprising Rapier looms, gripper shuttle loom, air-jet loom, water jet looms, Magnetic Weft-Inserting Looms) that use have all disposed weft selector basically at present, but the loom that can weave multiple parallel is arrow shaft, projectile shuttle, three kinds of looms of magnetic weft insertion, generally can knit 2～5 kinds of different parallels, can satisfy the requirements of weaving process of general textiles.But, along with the development of society, the Application Areas of textiles also more and more widely, the function of use of weaving also constantly promotes, textiles no longer has been confined to the purposes of clothes, footwear, cap and so on.Diversity to textiles has also proposed new requirement, more particularly has technological assembling cloth and special industrial cloth, and requiring has 8～12 kinds of different parallels to interweave.Therefore, the weft selector that disposes on the loom can't satisfy new technological requirement at all at present, has suppressed the lifting and the development of loom function, has hindered the development of textile industry itself and the development of other industry simultaneously.

It is two types that the weft selector that disposes on the present shuttleless loom is roughly sent out.A kind of is the weft selector of complete mechanical formula.Its feature is that to select the latitude presetting apparatus respectively to select the latitude actuating unit all be directly to be driven by machine power to realize selecting latitude action and function, and another kind of weft selector is to be combined by minitype electromagnet and mechanical actuating unit to constitute.Its feature is: selecting the latitude program controlled mode can be machinery control, also can be that data signal is controlled.Its know-why is: presetting apparatus output parallel exchange signal makes certain minitype electromagnet be produced action, down auxiliary at this minitype electromagnet then, making with this electromagnet has a corresponding mechanical actuating unit (is selected latitude to collude) to obtain Mechanical Driven power, make this actuating unit action and enter the operating position, and parallel switching motion and requirement are realized in the former actuating unit that is in the operating position position of deactivating simultaneously.

Above-mentioned two kinds of weft selectors have two.Major defect:

1, actuating unit power all leans on Mechanical Driven, at actuating unit to setting up a whole set of numerous and diverse transmission mechanism between the power source.Transmission link is many, the manufacturing cost height, and debugging difficulty is big, and fault is also many, stability and reliability are just poor, and minitype electromagnet has remanent magnetism to be not suitable for running up, and production efficiency descends.

2, limited the increase of selecting latitude quantity.As shown in Figure 1, because each actuating unit is when the Mechanical Driven, because power resources direction unanimity, each actuating unit (selecting latitude to collude) all must be on the same universal driving shaft, and the direction of motion during each actuating unit action is all consistent.Collude when exchange action parallel staggered " fighting " when each selects latitude, certainly will select latitude to draw back certain space length between colluding at each.But, after spacing out between elected latitude colludes, it is inconsistent to make each select latitude to collude when entering the operating position drop point of parallel, parallel drop point inconsistent, just have influence on the loom weft insertion device colluded, clips to parallel in the high-speed motion process accuracy and reliability, thereby have influence on the efficient of loom running.As shown in Figure 1: have 5 and select latitude to collude, can knit 5 kinds of parallels.Select latitude to collude A and select the spacing that latitude colludes between the B, respectively there is 40mm all around, elected latitude colludes A and finishes and select the latitude position of deactivating, when selecting latitude to collude B to enter the operating position and select latitude, make that the drop point gap of parallel A and parallel B is just very big, so just very difficult assurance weft insertion device can accurately collude in the high-speed motion process on same trajectories and clip to parallel A, accurately collude again and clip to parallel B, often appearing at just differs accurately to collude surely in the time of accurately clipping to parallel A clips to parallel B, causes weft insertion error.If elected latitude colludes quantity the more the time, the situation of weft insertion error also the more even can't run well at all.

3, along with after electromagnet uses a period of time, adopt what number steel on it, all to gather certain " remanent magnetism " thus influence the speed that electromagnet is carried out, cause wefting insertion to fail.

Summary of the invention:

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and good loom electromagnetism selects the latitude actuating unit to select the latitude accuracy.

Technical solution of the present utility model is:

A kind of loom electromagnetism selects the latitude actuating unit, its feature: metal shell is arranged, and the skeleton that installs coil in the housing installs coil on the coil rack, dress magnetic core in the coil rack, and magnetic core connects weft selecting rod, and the dress parallel installs mouth on the weft selecting rod.

Upper and lower end in coil rack is provided with upper and lower buffer stopper.The upper and lower end of housing is provided with upper and lower cover.The bar cover is set between weft selecting rod and the lower cover.Coil is made up of upper and lower two coils of mutual series connection.On coil rack, the magnetic core contact-making surface, the projection, the groove structure that are slidingly matched mutually are set.

The utlity model has following advantage:

1, the structure letter connects, fault is few, adopt electromagnetic force directly to drive the technology of actuating unit, omitted mechanically operated a whole set of transmission mechanism, make the total device more succinct, and power resources are reliable and stable, as long as there is power supply to exist, its power supply power just exists, as long as the power circuit fault-free, its kind of drive improves the stability of weft selector, reliability with regard to fault-free greatly.

2, function and accuracy improve greatly: because the execution power of each actuating unit comes from its inner electromagnetic force, make that its use is more arbitrarily convenient, both can independently use by single actuating unit, also can be used in combination by a plurality of actuating units.And when a plurality of actuating units are used in combination, make permutation and combination method between each actuating unit more convenient rationally, and each device is when entering the operating position, and parallel all drops on the same point, and the accuracy that makes weft insertion device collude the folder parallel improves greatly.The function of weft selector is improved greatly, can realize any conversion of 2～16 kinds of parallels, it is inconsistent to have solved increase of parallel kind and parallel drop point simultaneously again, the difficult problem that loom can't run well.

3, capability and performance is good, long service life, and applied range, debugging are conveniently.
