Description
Technical field
The present invention relates to a kind of yarn winding device and a kind of method of producing yarn package, in more detail, the present invention relates to a kind of yarn winding device and a kind of method of producing yarn package thereof, this method is by reducing in the vibration that produces in the yarn process and the high-speed winding yarn.In addition, the invention still further relates to a kind of electrical motor that yarn winding device preferably uses.
Background technology
At present known a kind of yarn winding device comprises an electrical motor, appends to a long spindle on the turning cylinder of electrical motor and is arranged in a bobbin holder on the spindle, wherein, a plurality of bobbins are installed on the bobbin holder as 8 bobbins, and yarn is wound on each bobbin with higher speed.
Yarn winding device can have a contact roller, and this contact roller contacts with the surface of yarn package on being wound into each bobbin yarn package is applied surface pressure when the rotation.This contact roller can rotate by the active drive of an electrical motor.
For example, in JP-B-7-33206, EP-B-234844 and US-A-4852819, disclosed such yarn winding device respectively.
Propose the two ends of bobbin holder in the axial direction and a position formation balance correction face between the at both ends in the document and carry out the regional balance correction to carry out high speed around yarn.This correction makes the basic critical speed of bobbin holder pass with less vibration and the vibration in the work speed district between the basic critical speed and second critical speed is remained on lower level, thus carrying out around yarn with 6000m/min around yarn speed.
If increase around yarn speed, the contact roller is also to rotate at a high speed accordingly.For the contact roller, must proofread and correct the overbalance of its rotation, reach in the end and regional balance is not being proofreaied and correct with yarn package position contacting place.
For reaching the purpose that improves yarn package output, the contriver attempts to utilize such yarn winding device with higher speed coiling yarn or utilize the long bobbin holder yarn of reeling.
For improving bobbin holder and the velocity of rotation that contact roller or utilizing the bobbin holder of length and contact roller, must be used in their electrical motor of driving and have higher speed and bigger size.Find now: if utilize at a high speed big electrical motor, when the coiling yarn, the overbalance of the electrical motor particularly overbalance of motor rotor be can not ignore.
If improve the rotating speed of electrical motor, increase by rotating caused centnifugal force, work speed (speed increases to stable rotating speed under the yarn state from halted state) is just near natural frequency.Particularly surpass 6 at winding speed, 000m/min and reach 7, under the situation of 000m/min or more speed, it is with regard to the critical speed of second order that surpasses bobbin holder and near the 3rd critical speed.In this case, if electrical motor be and be unbalanced, to such an extent as to vibration just becomes and in fact can not make winding speed increase to required level too greatly.
If the size of increasing motor, the natural frequency of electrical motor will descend, and causes the raising of centnifugal force owing to the increase of diameter.The raising of centnifugal force further makes the high-speed winding of yarn become difficult.
According to common practical application, the overbalance of electrical motor is proofreaied and correct in the end of the unbalanced rotor that mainly causes or in motor reel part near rotor tip.
By the electrical motor that is used for yarn winding device with lower under the situation that yarn speed is rotated, can come the overbalance of correcting motor by method commonly used, but under the bigger situation of electrical motor, just be difficult to the overbalance of correcting motor, this overbalance only be distributed in the end of rotor or the motor reel partly located near the motor reel of rotor tip in.
Find now: increase particularly in the hyper-speed yarn winding device at rotating speed, need utilize the technique device of any special use to solve this problem, in this hyper-speed yarn winding device, reach 7,000m/min or higher around yarn speed.
The objective of the invention is to be not less than 7 around yarn speed by providing a kind of, the yarn winding device of 000m/min solves the problems referred to above, the present invention also aims to provide a kind of and produce the method for yarn package, and the electrical motor of using in a kind of yarn winding device and the described production method also is provided based on this yarn winding device.
