The specific embodiment
In Fig. 1, show the workstation 10 of the textile machine of producing cross winding bobbin, here, this textile machine is the revolving cup free-end spinning machine.
This revolving cup free-end spinning machine has a plurality of this workstations 10 arranged side by side, that arrange in the same manner respectively of embarking on journey.
At spinning workstation 10 places, from deposit feeding to spinning yarn 17 the sliver (not shown) in spinning pot, yarn 17 is wound into cross winding bobbin 19 at wind2 18 subsequently by open-end-spinning mechanism 12.
The wind2 18 of these workstations 10 also has for the bobbin bank 8 that keeps cross winding bobbin 19 rotationally, having can be by yarn transversing mechanism 22 and the bobbin driver train 23 of independent electric motor driven traverse guide 1, and the bobbin driven roller 14 of bobbin driver train 23 is for example driven by electrical motor 27.
In addition, each workstation 10 of revolving cup free-end spinning machine has many additional, different yarn steering units or yarn treatment mechanism, and in order to realize the suitable operation of this class workstation, these yarn steering units or yarn treatment mechanism are essential.
Each workstation 10 for example is equipped with self-stopping gear (stop motion) 3, yarn derivation mechanism 20, mechanical type yarn storage device 2 and waxing attachment 5.
In addition, each workstation 10 has suction nozzle with battery unit 21, and suction nozzle with battery unit 21 is configured to rely on air for example to siphon away at the yarn 17 that runs to behind the broken yarn on the cross winding bobbin 19, and yarn 17 can be fed to open-end-spinning mechanism 12 so that joint again.
As shown in Figure 1, be used for the individual drive 24 of yarn derivation mechanism 20, the individual drive 25 that is used for suction nozzle with battery unit 21, the individual drive 27 that is used for the individual drive 26 of traverse guide 1 and is used for bobbin driven roller 14 and be connected workstation computer 6 by control line 28 to 31, workstation computer preferably links to each other with the centralized control unit (not shown) of free-end spinning machine by bus system 7 again.
Mechanical type yarn storage device 2 according to the present invention have two fixing, for example be supported on guide roll 38,39 on the housing of waxing attachment 5, and have the yarn deflection roll 36 of being installed by activity, in the spinning working process, loaded by yarn 17.
The yarn deflection roll is arranged on first spring element 32 for 36 this moments, and first spring element is fixed on again on the adjusting lever 35.
In other words, first spring element 32 is soft relatively springs.
Especially as shown in Figure 2, on adjusting lever 35, turning up the soil at interval with first spring element 32 is provided with the thickness d of 34, the second spring elements of second spring element
2Thickness than first spring element 32 is big, is at least 0.4mm.
Therefore the spring force of second spring element 34 is obviously greater than the spring force of first spring element 32.
This means that second spring element 34 is hard relatively springs.
Can be hinged with an actuating device by the limited adjusting lever of installing rotationally 35, especially thrust piston formula actuating device 37, this actuating device allows the restriction displacement of adjusting lever 35, and then has realized selectively that yarn deflection roll 36 is positioned at and meet yarn position (not shown) or operating position I as shown in Figure 1.
Function according to device of the present invention is as follows:
In the spinning working process, the yarn 17 that produces in open-end-spinning mechanism 12 is taken out from open-end-spinning mechanism 12 with constant yarn feed speed by yarn derivation mechanism 20 to be drawn and is wound into columniform cross winding bobbin 19 at wind2 18.
The yarn 17 that runs on the cross winding bobbin 19 traverses by the traverse guide 1 of yarn transversing mechanism 22 simultaneously, makes yarn run on the surface of cross winding bobbin 19 with cross-level.
If do not take appropriate measures, then because yarn traverses the yarn tension variation appears in the yarn 17 of motion continuously in winding process.
In other words, when yarn 17 traverses along the bobbin side of cross winding bobbin 19, occur significant yarn tension all the time and increase because yarn speed increases, and when yarn 17 traverses along the bobbin center of cross winding bobbin 19, yarn tension reduces, and yarn speed reduces in this process.
In order to avoid this yarn tension to change as far as possible, guided by mechanical type yarn storage device 2 according to the present invention before yarn 17 arrives yarn transversing mechanism 22 by the yarn 17 of yarn derivation mechanism 20 with constant yarn feed speed feeding, the different length of yarn requirement that this yarn storage device compensation occurs when yarn traverses keeps yarn tension almost constant thus.
In other words, by at least one deflection in the sheet spring element 32 and 34 that makes mechanical type yarn storage device 2, finish the length of yarn compensation automatically.
As shown in Figure 1, the first spring element 32 that is fastened on the adjusting lever of installing 37 that pivots is equipped with yarn deflection roll 36 in the end, first spring element 32 is positioned in operating position I at the yarn running route, make the yarn 17 of operation by yarn deflection roll 36 by deflection slightly, and yarn 17 is loaded with the yarn tension of the spring force of the spring force that depends on first spring element 32 or sheet spring element 32 and 34 in this process.
In the cross winding bobbin 19 that is wound with relatively little yarn tension, for example in dye bobbin, only make first spring element 32 deflection at the coiling on period, the result, this cross winding bobbin 19 is wound with the yarn tension between 2-3cN.
Especially in the high relatively cross winding bobbin with rove 19 of for example reeling greater than the yarn tension of 100cN, first spring element 32, the second spring element 34 that after the operation that begins to reel, recline at once, thus the spring force of two sheet spring elements 32 and 34 applies automatically.
In the case, in the bobbin traveling process, also guaranteed almost constant but high yarn tension.
