Description
Technical field
This invention relates to the method opening draw-gear, belongs to mechanical field, and this draw-gear is with the roller bearing pair of multiple drawing of fiber band.On draw-gear occupy transmission rolling shaft to and at least one input and output roller bearing between fiber band to be tauted, one input roller bearing to and at least one central roller to export roller bearing to instruction draw-gear on fiber band, especially to be tauted.Each roller bearing of draw-gear is at least indicating roller and a lower roller on one, and the right draw-gear of the roller bearing with multiple drawing of fiber band is also like this.
Background technology
Can know from DE10057699A1, an equipment of will installing on draw-gear is to process fiber band.On equipment, the fiber band between the input roller bearing of loading bay and draw-gear is through floating roller assembly and guide with the fiber band of conveying roller, thus the region of fiber band at least between conveying roller and the input roller bearing of draw-gear is stretched.Between conveying roller and draw-gear, fiber band will carry out awave orientation by three guide wheels.
DE102006014475A1 discloses a guide wheel unit, it be positioned in one as the right button roller bearing of transmission rolling shaft to and draw-gear input roller bearing between.Guide wheel indicates belt deflection position, and fiber band spreads out to the direction of motion sidewards uniformly at this, thus unties the extruding carried out fiber band in sensor cell areas.In order to make the fiber band of display also can spread out uniformly under different intensity and quantity, the deflection position of belt is adjustable.The shortcoming of this way is, installs new fiber band and requires great effort very much, because fiber band must be laid on independent belt deflection position.
When being partial to position by guide wheel in other words and starting fiber band, fiber band bears a frictional force, and this frictional force can make fiber band be partial to and input roller bearing to phase coadaptation.If open draw-gear now, take down the right upper roller of roller bearing and lower roller, the circuit of the fiber band started will get back to the right direction of input roller bearing.
In this way, just can in the weakest place of the fiber band of draw-gear, herein the usual central roller at draw-gear to and export roller bearing between, produce a thin spot.Risk will be produced like this when restarting machine, namely fiber band there will be the position of the extreme fragility of a local, make when the further process carrying out subsequent processing, namely on next device passage or corridor, must to dismantle fiber band, and to cause machine out of service.
Summary of the invention
Task of the present invention avoids producing weak location when opening draw-gear, and simplify the installation of new fiber band.
This task can have been come by a method with according to the draw-gear of demand for independence design.
Open in the inventive method of draw-gear at one, this draw-gear is taken out wheel carry out drawing of fiber band with multiple being rolled, transmission rolling shaft to and at least respectively by one on roller and lower roller instruction draw-gear input and output roller bearing between fiber band can be tauted.Input and output roller bearing between draw-gear first indicate additional one or more central roller pair.Different according to the machine that draw-gear is mounted, can one or more fiber band be guided into transmission rolling shaft pair, and the fiber band of an expansion pulvilliform formula can be set up in the region of deviator.Hereinafter, for simplicity, all fiber band is called.
The adjustment of fiber band can by the transmission rolling shaft of draw-gear to and input roller bearing between speed discrepancy realize.Advantageously, it can be undertaken by awave the deflection on deflection position that is static or that rotate of fiber band in whole or in part.Can produce friction by the deflection of fiber band, this frictional force can carry out suitable adjustment to it before fiber band enters draw-gear.In addition, also by deflection fiber band is sprawled, homogenising, thus make fiber band in draw-gear can better evenly stretching.
Opening draw-gear, is at least opening the input of draw-gear and/or central roller to front, transmission rolling shaft to and draw-gear between the adjustment of fiber band to reduce or fully phase out.Can avoid thus when opening draw-gear completely, when the upper roller of draw-gear is taken down from lower roller, balanced adjustment is carried out in the direction that the fiber band flowed into is pulled transmission rolling shaft right.In contrast, inventive method can reduce or fully phase out adjustment before opening draw-gear whereby, thus prevents the thin spot of fiber band from producing.Particularly central roller to and export roller bearing between main towing area there is the danger of thin spot.On only right with input and output roller bearing draw-gear, its unique towing area is exactly the main towing area that thin spot produces.Therefore at potential thin spot, input and/or export roller bearing on, before generation, keep clamping fiber band until reduce or abandon adjust fiber band, this point is very important.Before opening draw-gear, fiber band relaxes, under being no longer in harmful adjustment when opening.Lax can by shorten transmission rolling shaft to and draw-gear between, the passage of fiber band process carries out, or can by extra to transmission rolling shaft to requiring more fiber band, minimizing draw-gear and transmission rolling shaft between adjustment carry out.
The present invention particularly advantageous place is, when opening draw-gear and reducing the adjustment of fiber band, first to the awave deflection partial cancellation of major general, thus shorten fiber band transmission rolling shaft to and input and/or central roller between the passage distance that has to pass through.Then by taking down upper roller from lower roller, to major general's input and/or central roller to or draw-gear other roller bearings to or whole draw-gear open.When draw-gear is opened, fiber band is also relaxed thereupon accordingly.Fiber band is pulled back, and cause thus central roller to and export roller bearing between, on the fiber band in pressure bar region, especially produce weak location just can avoid.
When awave deflection indicates deflection position, one or more top and deflection position, bottom, and during in order to stop being partial to the top and/or deflection position, bottom of removing fiber band, be also useful.This kind of situation is especially liked occurring in when removing deflection position by the lateral transfer direction of fiber band, namely by taking down deflection position, top or moving down deflection position, bottom, shorten transmission rolling shaft to and input and/or central roller between the channel distance of fiber band process of clamping, thus relaxed fibre band.
Especially it is advantageous that first by the deflection position that fiber band the first half is installed, then mention to major general's input and/upper roller that central roller is right.The deflection position, top of draw-gear and the direction of motion of upper roller are identical, thus the construction stage of the method can be carried out easily.
The present invention particularly advantageous place is, the upper roller of deflection position, top and draw-gear can so be installed on the load arm of draw-gear, namely first installs deflection position, top, then just installs the upper roller of draw-gear.Mention and can be undertaken by a motion of draw-gear.Thus, opening with regard to being connected with the relaxation phase of the fiber band first carried out of draw-gear, carries out early than being taken down from lower roller by the upper roller of draw-gear.Fiber band also can keep clamping on draw-gear, until it is relaxed before draw-gear.As long as so do not pull back on the fiber band of draw-gear, the clamping problems of draw-gear so just can be solved.
Especially it is advantageous that when deflection position is by pneumatic, hydraulic pressure or electronic moving in a release position.Thus can before draw-gear be opened, by controlling to the thrust loosening a deflection position of fiber band.
Another particularly advantageous place of this invention is, when draw-gear stops first by conveying roller, as long as several centimetres under normal circumstances, can be opened by fiber band, then just open draw-gear.By the promotion of transmission rolling shaft to fiber band, transmission rolling shaft to and the draw-gear of fiber band between adjustment just can shorten and even all cancel, thus draw fiber band last time from draw-gear when avoiding opening draw-gear.
The particularly important is, first at least again shutting draw-gear in the region inputted and/or central roller is right, then just again recovering the adjustment of fiber band.So just can guarantee, fiber band not comprise the thin spot not allowing to occur.
The draw-gear of invention indicates multiple roller bearing to carrying out drawing of fiber band.Fiber band a transmission rolling shaft to and at least one input and/or export roller bearing between be tauted, mainly one (at least one) input roller bearing pair, also can be sometimes two even three centres and export roller bearing to instruction draw-gear between.Each roller bearing of draw-gear is at least indicating roller and a lower roller on one.Can be made by machinery or the cooperation of electric power or control, at least open the input of draw-gear and/or central roller to front, the transmission rolling shaft of draw-gear to and input roller bearing between the adjustment of fiber band can shorten, even fully phase out.The cooperation of machinery or electric power or when controlling to make the adjustment of fiber band avoid the tight position of the fiber band on opening between roller and lower roller, produces pulling back to fiber band that be harmful, that send from draw-gear.Mechanical cooperation or control can so act on, and namely coordinated by machinery and combined by the building component that draw-gear and fiber band adjustment cause, thus make when adjustment reduces, draw-gear just can be opened.By cooperation or the control of electric power, can make to adjust the building component caused to remove from fiber band, and transmission rolling shaft can be made all or on most of draw-gear out of service moving, thus extend transmission rolling shaft to and draw-gear between fiber band, to reach the effect loosening fiber band.
Adjust transmission rolling shaft to and input roller bearing between fiber band time, arrange deflection position, one or more top and deflection position, bottom to be favourable, they can make fiber band be turned to by awave.
In order to reduce or cancel deflection and in order to make the adjustment of fiber band, its deflection position, top and/or deflection position, bottom first will being allowed to remove from fiber band.Deflection position by the device by a fixing deflection position, can be removed open fiber band from vertical direction by this.The awave deflection of fiber band can be eliminated thus or reduce skew.The reduction of fiber band adjustment can make the passage between fiber band clamped position shorten.
The especially favourable place of this invention one is, when opening draw-gear, at least can by deflection position and an input and/or central roller to carry out electric power or the carrying out of machinery be connected, thus the adjustment of reduction or elimination fiber band, especially awave deflection is at least partly eliminated, and then at least allows input and/or central roller to being opened.Importantly, the elimination of awave deflection or reduction are carried out before draw-gear is opened, and central roller to and export roller bearing between the fiber band of critical position not weakened.
The especially favourable place of of this invention is, the upper roller of deflection position, top and draw-gear can so be installed on the load arm of draw-gear, namely open draw-gear also namely on carry load arm time, first by the deflection position, top of or all, then the upper roller of draw-gear is mentioned.Such as it can carry out by the sizing of a corresponding load arm or by the guider of a corresponding hinge or deflection position and upper roller.
The quite favourable place of this invention one is that the deflection position, top of or all and the upper roller of draw-gear can be installed on the load arm of draw-gear, and at least input and/or the right upper roller of central roller can be arranged in an elongated hole.When opening load arm, first can mention with the deflection position, top that load arm is tightly connected thus, being then installed to input in elongated hole to major general and/or the right upper roller of central roller is mentioned.Input and/or central roller to clamping corresponding fiber band until deflection position, top removes from fiber band, or are at least removed, and fiber band is relaxed.Then just move upward by the load arm upper roller that motion drive inputs and/or central roller is right upwards, thus fiber band is gained freedom.
When being made by pneumatic, hydraulic pressure and electronic method deflection position can move in a release position, so can controlling accordingly when opening draw-gear by one, first loosening the deflection position of fiber band and then opening draw-gear.
It is beneficial that, when opening draw-gear, at least can by the method for electric power or machinery by transmission rolling shaft to input and/or central roller to being so connected, namely in order to reduce or cancel the adjustment of fiber band, open fiber band when draw-gear is out of service by transmission rolling shaft air exercise, then just open draw-gear.So also can reduce transmission rolling shaft to and draw-gear between the adjustment of fiber band, and avoid fiber band occurring thin spot.

Other advantages of this invention illustrate detailed hereinafter, wherein:

Detailed description of the invention
Fig. 1 illustrates graphic draw-gear 1, it has the fiber band 2 of a stretching, is and then a calender roller bearing to 3 and is placed on the rolling disc 4 on can-like device 5 side.Fiber band 2 has been introduced to draw-gear 1 to 6 by transmission rolling shaft.At transmission rolling shaft to having installed deflection position 7 between 6 and draw-gear.On deflection position 7, fiber band 2 is turned to by awave lower portion deflection position 8.1 and 8.2 and deflection position, top 9.1 and 9.2.Fiber band 2 is transmitted the input roller bearing of roller bearing to 6 and draw-gear 1 respectively and clamps 10.Input roller bearing to 10 and central roller to 11 between and central roller to 11 and export roller bearing to 12 between, fiber band 2 is stretched by with predetermined form.Central roller has installed a pressure bar 13, its guide fiber band 2 to 11 and output roller bearing between 12.In the region of pressure bar 13, fiber band 2 is the most responsive because of stretching.If draw-gear 1 has been opened, when fiber band 2 because transmission rolling shaft to 6 and input roller bearing to 10 between too high adjustment delay being pulled back, this position will produce the thin spot be not allowed to.
In order to open draw-gear 1, the load arm 14 of draw-gear 1 and run-on point 15 can be swung.As shown in the figure, run-on point 15 can be arranged on and export roller bearing in the region of 12.In the operation example of showing, load arm 14 swings around run-on point 15 with the form of double-head arrow.In other operation, also can allow load arm 14 on run-on point 15, the entrance of draw-gear 1 rotates, or install a turning cylinder in the side in the front of the roller bearing of draw-gear 1, thus the side of roller bearing is upwards turned over.
On load arm 14, the roller bearing of draw-gear 1 is installed on support 20,21,22 and 23 the upper roller 16,17,18 and 19 of 10,11 and 12.Upper roller 18 and 19, between being tightly fixed on based on their turning cylinder on 22 and 23, and be only assigned with export roller bearing to 12 a lower roller.In contrast, upper roller 16 and 17 has been imported into elongated hole 24 and 25 on support 20 and 21.When elongated hole 24 and 25 can make load arm 14 rotate around run-on point 15, upper roller 16 and 17 still remains on their lower roller, as long as the minor axis of the upper roller 16,17 of long guiding hole 24,25 reaches the back side of elongated hole 24,25.Then they could lift from lower roller together with load arm 14.So the clamping of fiber band 2 can not immediately input roller bearing to 10 and central roller to 11 between carry out, but to first upper roller 16,17 to be lifted from lower roller together with load arm 14.
Contrary with the bearing block of elongated hole 24,25, the deflection position, top 9.1 and 9.2 on support 26 is tightly arranged on load arm 14.As long as load arm 14 rotates around run-on point 15, so top deflection position 9.1 just can be lifted from fiber band 2 with 9.2 together with load arm 14.First the deflection of fiber band 2 can reduce, then will eliminate completely thus.Present fiber band 2 is in button roller bearing between 6 and 10 of input roller bearing not have the state of tension force or slight tension, and its upper roller 16 and 17 also lies on lower roller always.When next upper roller 16 and 17 lifts from lower roller, fiber band 2 can not be pulled back again, and can avoid on fiber band, produce critical thin spot.
Even if in this operation example, deflection position, two top 9.1 and 9.2 being connected with load arm 14 all tightly, but if only have deflection position, top 9.1 to be lifted together with load arm 14 with in 9.2, be also enough.This point is applicable to elongated hole 24 and 25 too.When only having one to be placed in elongated hole 24 or 25 in upper roller 16 and 17, be also enough.Importantly, when opening draw-gear, fiber band 2 central roller to 11 and export roller bearing to 12 between position, be guaranteed as lead position by the long long chuck of fiber band 2.
The closedown of draw-gear 1, first upper roller 16 and 17 to be clamped to again input roller bearing to 10 and central roller on the lower roller of 11, then make the axle journal of the upper roller 16 and 17 in elongated hole 24 and 25 again move upward.Again move to closed position by load arm 14, top is partial to position 9.1 and 9.2 and again imports in the deflection position of fiber band 2, thus make fiber band 2 being diverted again in deflection position 7 Wave formula.
Illustrate another mode of operation of this invention in fig. 2.Fiber band 2 is transmitted roller bearing and has guided draw-gear 1 into 6, is stretched there, has then been placed to filling shape device 5 side.At transmission rolling shaft to having installed deflection 7 between 6 and draw-gear 1, it makes, and fiber band 2 is awave to be turned to.
The load arm 14 of draw-gear 1 has installed switch 30.When opening draw-gear by load arm 14, switch 30 will be opened, thus makes control 31 produce a driving, and this driving can make transmission rolling shaft move to 6, promotes that fiber band 2 is advanced to the direction of draw-gear 1.Although there is the guiding of fiber band 2, draw-gear 1 barred, thus cause the transmission rolling shaft of draw-gear 1 to be extended the fiber band 2 between 10 6 and input roller bearing.Thus, transmission rolling shaft is reduced 6 and the adjustment of input roller bearing to the fiber band 1 between 10 or is cancelled.
After aforesaid operations has carried out, load arm 14 can rotate around the point of rotation 15, and draw-gear 1 also can be opened.Fiber band 2 also can not be pulled back because lack adjustment, and central roller also can not be compromised the thin spot between 12 11 and output roller bearing.Drive transmission rolling shaft to 6 driving 32 can become transmission rolling shaft that the normal guiding for fiber band 2 is responsible for 6 supervisor drive, an or independent driving, it can balanced adjustment.
In this example, the closedown of draw-gear 1 can be undertaken by traditional method.
Illustrate the operation of the another kind amendment of this invention in figure 3.Here the adjustment of fiber band 2 is by the strong deflection more or less of fiber band 2, and is undertaken by the deflection position 8.2 in deflection position, two bottoms 8.1 and 8.2.If draw-gear 1 is opened, so will the control shown do not had to send control signal by one in this example,, hydraulic pressure pneumatic to deflection position, bottom 8.2 1 or electronic driving, by this driving, deflection position 8.2 brings out by the occlusion from fiber band 2.Thus, the transmission rolling shaft of draw-gear 1 will be shortened or cancel 6 and the adjustment of input roller bearing to the fiber band between 10.Pulling back to fiber band 2 would not be there is when opening draw-gear 1.When draw-gear 1 is closed again, so in contrary order, first load arm 14 can be thus lifted to above fiber band 2 together with upper roller 16,17,18,19, and is clamped.Then bottom deflection position 8.2 can move towards the direction of the deflection position of fiber band 2 again, thus can produce the adjustment of a new fiber band 2.The planned stretching of fiber band 2 just can proceed.
This invention is not limited to the mode of operation provided in example.Although operation example show only and lifts and input the upper roller right with central roller subsequently and restart first, this invention also can centering roller or restarting only to the upper roller that input roller bearing lifts subsequently and inputs and central roller is right first.This is for only with an input and output roller bearing pair, and do not have central roller to or with multiple central roller concerning draw-gear be also significant.Amendment is within the scope of the claims possible.
