Description

Be used for the device of operation touch roll and the method that is used for the operation touch roll
Technical field
The present invention relates to the device that a kind of equipment being used for single shaft or biaxial stretch-formed polymer film operates touch roll.Especially, the present invention relates to a kind of so that touch roll about the device of the variable location of polymer film winding roller outside face.In addition, the present invention relates to a kind of the application of the invention device and in the method for the equipment operation touch roll that is used for biaxial stretch-formed polymer film.Especially, the present invention relates to a kind of so that touch roll about the method for the variable location of polymer film winding roller outside face.
Background technology
The first step of all method that the biaxially oriented film that comprises polymeric material is made is to push at the upper film to molten polymer of roller (cooling roller) by mould, and the surface of described roller remains on and is lower than the separately glass transition temperature of poly-mer.The surface of described roller is cooled to amorphous state rapidly with poly-mer.
Next step of described method comprises that the film that will produce by the method for being familiar with before stretches in vertical (machine) direction and/or horizontal direction, and horizontal direction is generally the stretching step vertical with machine direction.These stretching step can be independent carrying out or can carry out one by one, perhaps can carry out simultaneously.With regard to sequence stretching, drawing process itself is carried out by two machine units, usually at first vertically/machine direction (that is, the direction of the travel path of polymer film on stretching device) and then at horizontal direction.With regard to stretching simultaneously, move and need to simultaneously tensile force be applied to membrane material at both direction (usually being perpendicular to one another) in the stretching of vertical (machine) direction and horizontal direction, film is along film mobile route high-speed mobile on stretching device simultaneously.
Finish in case draw step, the polymer film that is drawn is quilt " thermal finalization " or crystallization under tension, and along with the thermal drop that begins from high temperature and the continuous temperature that reduces.The thermal finalization step prevents that film from shrinking and gets back to the shape that it does not stretch, and at polymer film plane locking molecular orientation.Therefore, the orientation of the polymer molecular chain of acquisition is the high strength of oriented film and the reason of high rigidity.
At last, single shaft or biaxial stretch-formed polymer film are directed to winding roller, and final polymer film is reeled to described winding roller and is used for further processing or storage.Batching by rotating described winding roller in the method for final polymer film, the diameter of described roller (the perhaps bale packing on roller) increases continuously.In order to be squeezed to winding roller (the perhaps bale packing of the polymer film on winding roller) with identical set pressure from stretcher film out, and use touch roll.Described touch roll with stable force applications to the polymer film outermost layer that is reeled to winding roller (perhaps having batched to the bale packing of the polymer film of winding roller).
When stretching step at last polymer film is batched to winding roller the time, need to process from two of prior art known problems:
-hold stable the increasing of diameter of the winding roller of the polymer film of having rolled, such fact so that the adaptation of the position of the relative winding roller of touch roll must continue.
-in the process that is wound to the winding roller step, polymer film is advanced at a high speed towards winding roller, and the bale packing that comprises the described polymer film of rolling continuously becomes non-circular, has at least a little.Therefore, can form the vibration of contact/winding roller unit, cause being applied to the variation of the contact of polymer film outer layer, described polymer film outer layer is wound to winding roller (perhaps being reeled to the bale packing of the polymer film of winding roller).This variation that is applied to the pressure of the polymer film that is wound do not expect, this is because it is for the polymer film significant adverse of rolling.
In order to overcome this problem, prior art has proposed to carry out two step pressure adaptations.Be arranged in the diameter of bale packing of polymeric material of coiling at winding roller place in the process that increases, the constant pressure that is applied to the pressure roll of winding roller is kept by the mode by leverage.In addition, because vibration is that cause and pressure adjustment carry out necessity along the distance that is approximately some (near 30) millimeters (mm) changes by the hydraulic damping cylinder vibration damping.Self moves described roller along one or several Linear guide.Such layout causes the minimizing of problem.Yet, it is considered to totally unfavorable, and the touch roll/action need of winding roller unit in whole equipment is in the multipart layout of the connection location of roller, in the long period of operation process, so the gap at connection location increases, cause link to turn to not mobile quietly.Finally, whole equipment operating must often stop in order to the parts of the use of the abnormal touch roll of work/winding roller unit are resetted.
Document EP-B1423318 has proposed a kind of counter controls for the linear electric motor device, and it is in line with keeping the target of improved contact to drive touch roll whole polymer film being batched to the process of winding roller.The power of contact (that is the power that, is usually produced by linear electric machine) can change in order to guarantee the as far as possible uniformly mode that is applied as of contact according to vibrational state.This layout causes that the power on the moving-member of drive motor increases or reduces, thereby and cause at touch roll and winding roller, the power that perhaps is wound on the contact wire between the bale packing on the winding roller increases or reduces, preferably, so that compare with non-correcting state, alleviation campaign between two rollers be reduced to minimum or even vanishing (perhaps tending at least vanishing), therefore, thereby prevent N/R vibration (variation of the distance between Relative Vibration or the roller).
Use the linear electric machine instrument to be used for preventing vibrating or two rollers between the relative variation of distance, its main shortcoming is that linear electric machine (as using) is owing to fixed magnets is easy to be subject to because the impact of the significant slot effect (cogging) that the magnetic pole of limited amount causes along linear (open loop) circuit arragement in prior art EP-B1423318, on the one hand, wherein slot effect is difficult to (if not can not) and makes the continuous line pressure control that is applied towards winding roller by touch roll is provided, on the other hand, suppose the variation of vibration-generating and the relative distance between winding roller and touch roll in the process of the process of batching the drawn polymer film, affect effectiveness in vibration suppression.
Summary of the invention
