Abstract
Feed tension variations on a warp knitting machine are reduced by deflecting the yarn path between the beam and the needles with a resilient guide rail (19). The rail (19) is supported on a gas cushion (16). An inflated tube (18) is situated inside a shell (15) that has openings (21) for a support leg (22). The tube (18) can be filled with air through a valve (26) at its end.
Description
The present invention relates to a kind of warp knitting machine with yarn flake tension compensation device.Described compensation arrangement is arranged between axle and sley point, but and has a guide rod of elastic yield.
A kind of like this warp knitting machine is disclosed in american documentation literature US2637184.Guide rod wherein is fixed on the cramp bar by several spring arms of arranging at certain intervals.Be attached to yarn sheet on the described guide rod or that lead by guide rod and in knitting cycle, keep tensioning state, comprise that yarn consumption and yarn admission velocity do not keep tensioning simultaneously yet.The release of one section yarn particularly can appear suddenly when knocking over.This can cause the marking occurring on finished product, promptly so-called " watermark " under the very high yarn feed speed and/or the very high speed of service.
Task of the present invention is, a kind of warp knitting machine of mentioned kind is provided, and it also can produce flawless product under the very high speed of service and/or very high yarn feed speed.
The present invention to the solution of above task is, described guide rod through supporting members support at least one air bag.
In this structure, the quality that moves in compensating motion only limits to the sub-fraction of described guide rod, supporting member and airbag wall.So described guide rod can carry out desired compensating motion at a terrific speed.In addition, can also adapt to various conditions well by selecting the interior pressure of air bag.
Particularly advantageous scheme is, a blown tubular air bag is arranged on the inside of a pillar, has perforate on the sidewall of this pillar, and described supporting member passes this perforate.Described pillar can allow air bag to adopt higher relatively interior pressure, and it can bring advantage to many purposes.In addition, also can obtain a kind of very compact structure.
The scheme of another kind of suggestion is that described pillar is a stay pipe that is fixed on the frame.Here utilized dual-use function, made the structure of described yarn flake tension compensation device compact more.
A kind of favourable scheme is to be provided for the cover plate of the open section of perforate between airbag wall and pillar wall.This structure can prevent that the part airbag wall from passing perforate and outwards extruding.
In a kind of preferred embodiment, an end of described supporting member has a bearing, and the other end has a composition surface that is used to connect described guide rod, is an interlude that the cross section is less between guide rod and composition surface, and this interlude passes described perforate.This structure can adopt the less supporting member of quality, and particularly described interlude adopts the round pin shape, the cross section of two ends only exceed corresponding round pin a little.
In a kind of favourable mode, fill air in the described air bag.So do not need special gas.
A kind of favourable scheme is, described air bag has the valve that is used to inflate with exhaust.This valve can allow to change the internal pressure of air bag.Pressure change even also can carry out at run duration.
Another kind of favourable scheme is that described valve is arranged on an end of pillar.Be in this locational valve even in equipment running process, also be convenient to operation.
The present invention is further illustrated for a contrast embodiment shown in the drawings below.
Fig. 1 represents the partial view of a warp knitting machine,
Fig. 2 represents the stereogram of yarn flake tension compensation device of the present invention, has wherein made broken section.
Warp knitting machine as shown in Figure 1 has one through compiling workspace 1, and yarn 2 and 3 is from introducing through axle 4 or 5, and leads to finished product 6.Described warp knitting machine has a sley bar 7 that comprises sley point 8, and the sley bar 9 that comprises sley point 10.Yarn 2 guides by a fixing guide pipe 11 and a yarn sheet tensioning compensation arrangement 12 between axle 4 and sley point 8 described.Yarn 3 guides by a fixing guide pipe 13 and a yarn sheet tensioning compensation arrangement 14 between axle 5 and sley point 10 described.
The structure of described yarn sheet compensation arrangement 14 is seen shown in Figure 2.
The inside as the pillar 15 of support column use an air bag 16 is arranged, described pillar links to each other with frame in its end at least, and the inner chamber 17 of described air bag is filled with air, and its pressure surpasses environmental pressure.Described air bag 16 has hose wall 18, and it is being pressed on the inner circumferential surface of pillar under the air effect of being sealed.A guide rod 19 is bearing on the air bag 16 by supporting member 20.On the circumference of pillar 15, be provided with perforate 21 for this purpose.Hole shape among the figure is a slit.The interlude 22 of the round pin shape of described supporting member 20 stretches out from this perforate 21.In the inner of described interlude a bearing 23 is arranged, it directly or indirectly is placed on the described airbag wall, perhaps links to each other with air bag.A composition surface 24 is arranged in its outer end, and it links to each other with described guide rod 19 with fixing or removable mode.Described composition surface 24 for example is positioned on the special-shaped top, and this top is screwed on the interlude of round pin shape, and the guide rod 19 of cavity section is shifted onto on this top.The cross section of described interlude 22 is less than the cross section on supporting member 23 and composition surface 24.
Outwards extrude for the outer wall that prevents air bag 16 passes perforate 21, be provided with a cover plate 25, it be shaped as a semicolumn shell.End at described pillar 15 is provided with valve 26, can be similar to the doughnut valve by this valve air is sent into inner chamber 17 or discharge internally.Mode can make the condition of the warp knitting machine of the elasticity of air bag and running be complementary according to this.
If a yarn sheet then will produce a component diametrically through described guide rod 19 guiding and guiding at work, the elastic force that can make guide rod 19 overcome air bag by this component inwardly compresses.If lax, for example knocking over causes when relaxing, and air pressure will outwards extrude guide rod 19 again, makes the yarn of yarn sheet keep enough tension force.Its governing speed is wanted enough height, makes yarn sheet be attached to all the time on the guide rod 19 under different yarn consumption amounts and higher running speed.So can satisfy the condition of making no defective product, very high in the machine speed of a motor vehicle up to now, and also guide takes place under the situation of unfavorable variation, almost can't realize this point.Can do various variation and need not to break away from basic design of the present invention the above embodiment.For example the perforate 21 of described shape of slit can be used independently circular hole replacement.Described supporting member 20 also can pipe axially on one section extension is arranged.
