Background technology
From the known such winding mechanism of DE 25 18 646 A1.The contact pressure that acts on the bobbin on the driving roller has influenced the density and the bobbin stability of bobbin dramatically.Therefore, for example, under less and constant as far as possible contact pressure, produce dye bobbin.And on the other hand, if the expectation bobbin has good yarn extraction performance, then when the beginning of reeling, should have very big contact pressure, and contact pressure reduces along with the increase of bobbin diameter.
The contact pressure of bobbin depends on the moment that acts on the bobbin bank on the one hand, depend on the weight of bobbin on the other hand, and the weight of bobbin increases along with the increase of diameter.In order to obtain constant contact pressure, therefore the moment that acts on the bobbin bank must reduce along with the increase of bobbin.Reducing at needs under the situation of contact pressure, also is like this.Generally speaking, in the process of tube forming, moment at first increases the contact pressure of bobbin.Under the situation of a certain bobbin diameter, the weight of bobbin is enough to apply required contact pressure.So want the adjustment (adjusting) lever device so that under the situation of this bobbin diameter, do not have moment loading on bobbin bank.Be accompanied by the further increase of bobbin diameter, the action direction counter-rotating of moment, leverage has reduced the contact pressure of the bobbin that is caused by weight.
After new bobbin inserted back or broken yarn, bobbin must be accelerated.Here can expect using independent driver to this serviceability.Yet if can be as in conventional operating winding, using identical actuator to remove to quicken bobbin, the structure of winding mechanism can be simplified greatly so.Yet, must be noted that in order to quicken bobbin driving on the roller to have enough contact pressures.DE 41 21 775 A1 disclose and have had the winding mechanism that drives roller, and wherein the contact pressure of bobbin can also automatically be regulated rapidly according to operating conditions (for example after broken yarn).This device has the leverage of band force-input device, and this force-input device produces basic the loading or off-load in the tube forming of routine.In order to make contact pressure be suitable for other operating conditions, also be provided with pneumatic cylinder, in whole tube forming process, it is reverse that pneumatic cylinder acts on the turning effort that the moment on the bobbin bank can not make it act on the bobbin bank.
Summary of the invention
From the above-mentioned background technology, the present invention is based on such purpose, promptly simplify carry out in order to quicken bobbin said bobbin is acted on the adjusting that drives the contact pressure on the roller.
In order to achieve this end, a kind of method of operating the winding mechanism of textile machine has been proposed, this winding mechanism has leverage; The bobbin bank that passes through that this leverage is used to control bobbin acts on the contact pressure that drives on the roller, and this leverage has force-input device, and this force-input device is placed on the throw of lever and applies variable torque on said bobbin bank; Wherein, When said tube forming, moment is at first loading said bobbin on the direction of said driving roller, and in the further forming process of said bobbin, reduces the load on the bobbin; And; In order to quicken said bobbin, so control said force-input device and be applied to the power on the said throw of lever, promptly this power contact pressure of making said bobbin be applied on the said driving roller is enough to carry out said acceleration.
In this case, use the simple device that supplies conventional operating winding to use according to the method for the invention, wherein engaging on it has the effective lever arm of said force-input device to change along with the change of bobbin diameter.According to the present invention,, regulate the power effect of said force-input device according to the position of said leverage in order to quicken bobbin.For according to the method for the invention, in any case what in accelerator, use is the identical force-input device of force-input device that all needs with conventional operating winding.Therefore, need not extra force-input device.
Preferred implementation according to the inventive method; If act on the squeese pressure that moment on the said bobbin bank helps said bobbin; The power that is used to quicken that then said force-input device applies remains unchanged with respect to the operating winding of steady (stationary); And different with the pulsation-free operating winding is that when the moment on acting on said bobbin bank reduced the load on the said bobbin, said force-input device did not apply any power in accelerator.
This embodiment is simple especially, and this is because said force-input device only need reduce load or remain unchanged.Be pressed onto when driving on the roller when said bobbin is applied moment on bobbin bank, the bobbin diameter is less.This moment, the moment of inertia of bobbin was less too, so the contact pressure of conventional operating winding is enough to quicken bobbin.If bigger bobbin is pushed towards leaving the direction that drives roller owing to act on the moment on the bobbin bank, then the load of said force-input device reduces to cause at once required contact pressure to increase.Large diameter bobbin has corresponding big weight.Therefore, also can be in accelerator owing to the minimizing of cancelling load realizes that corresponding contact pressure increases.Yet for acceleration, this also is necessary, and this is because big bobbin also has large rotating inertia.In this manner, the squeese pressure of bobbin increases along with the increase of its inertia.
In order to achieve this end, a kind of textile machine winding mechanism has also been proposed, this device has leverage; The bobbin bank that passes through that this leverage is used to control bobbin acts on the contact pressure that drives on the roller, and this leverage has force-input device, and this force-input device is placed on the throw of lever and applies variable torque on said bobbin bank; Wherein, When said tube forming, moment is at first loading said bobbin on the direction of said driving roller, and in the further forming process of said bobbin, reduces the load on the said bobbin; And; In order to quicken said bobbin, control setup is so controlled said force-input device and is applied to the power on the said throw of lever, and promptly this power contact pressure of making said bobbin be applied on the said driving roller is enough to carry out said acceleration.
Embodiment according to apparatus of the present invention; When the moment on acting on said bobbin bank helps the contact force of bobbin; Said control setup applies said force-input device for acceleration power remains constant, and, if the moment on the said bobbin bank had reduced the load on the said bobbin before quickening; Then said control setup is so controlled said force-input device at period of acceleration, so that said force-input device does not apply any power.
