Description
Technical field
The device that is used for yarn crank motion (yarn traversing), yarn is wrapped on the bobbin that is installed in the weaving loom operating unit winding mechanism, this device comprises: row's vertical reciprocating lever that operating unit shared, this reciprocating lever with make it to produce the reverse actuator of (reverse motion) of straight line and connect, and connects with the control system of determining this reciprocating lever lifting traverse route, this vertical reciprocating lever is parallel to and is assigned to a vertical roll of arranging operating unit simultaneously.
Background technology
The yarn crank motion is carried out by the mode that continuous reciprocating lever advances along machine operation unit one side usually in the bobbin winding process of weaving loom (such as rotor spinner, wire coiling machine or two-for-one twister).In a lot of operating unit of the quantity of in a row arranging, reciprocating lever reaches for example 30 meters, therefore has sizable weight.
In winding process, cross-wound bobbin tube, cylindrical shape bobbin or conical bobbin rotate, its surface is wound at winding roller, the pivot center of this winding roller is parallel to the axis of reciprocating lever, and reciprocating lever twines according to bobbin and reverses as straight line, and its lifting traverse correspondence the straight length of the cylindrical package of spool (reel cylindrical package) of the bobbin that twines simultaneously.Because machine productivity, the speed that is transported to yarn on the bobbin that twines is higher, and this reverses with regard to the straight line that needs reciprocating lever and also has high-frequency.
From forming the angle of cheese package (cheese package), if the route of reciprocating lever has saw shape shape, so that the constant airspeed of reciprocating lever, and promptly transfer the identical speed of opposite sense at dead center position, then this will be needed situation.
In fact, especially can not reach perfect condition because of the huge inertial mass of reciprocating lever.Reciprocating lever is restricted in deceleration and the acceleration at dead point, and the change of velocity reversal can continue a time gap that must need on the dead point.At this moment in the interval, yarn is not the rising that forms required cheese package in the rising that the helix line of bobbin surface deposition institute foundation has, but self is reduced to zero rising at the place, dead point, and the solid wire of yarn deposits overlappingly.Yarn is these some place accumulations on bobbin, and the diameter of package increases very fast in this position.
Prevented this phenomenon by improving reciprocating lever in the motion of dead center position.In a kind of solution commonly used, it is constant that the lifting traverse keeps, and move with a direction and second direction simultaneously the position at two dead points.In the commonly used solution of the second, the amplitude of lifting traverse changes, and the position at two dead points moves with mutual opposite direction, and the amplitude by this moving lifting traverse alternately increases and reduces.From the angle of package quality, the second solution is more favourable, yet is being driven by cam mechanism, or servomotor torque constant do not change in the situation that the mechanism that turns to drives, and this scheme is not easy to realize.
At reciprocating lever during with constant speed movement, the required power of its driver train is relatively little, because power demand only is used for overcoming passive resistance and makes yarn deflection.On the dead point, the variation of the power generation essence of driver train at first is in order to bounce back, thereby and gives inertia energy for the quality of reciprocating lever.This point can be by electrical motor large specified drive torque, and/or produce the kinetic energy accumulation by the inertial mass of braking reciprocating lever before the dead point, and repeat to discharge the energy of accumulating during the startup operation of reciprocating lever after at the dead point and solve.The energy of reciprocating lever is accumulated as the rotation energy of driver train usually, yet, if in the situation that driver train is implemented to reverse for servomotor torque constant, on the contrary, inertial mass that also must braking drive organ or moment of inertia also make driver train accelerate subsequently, and the drive torque of servomotor torque constant or power must be very high.The servomotor torque constant that drive torque is high has huge moment of inertia, and this has increased the total amount of the moving-mass that reduces, and therefore the increment of obtainable reciprocating lever acceleration/accel is less or do not have.
Guaranteeing outside the required shape in package border on the bobbin that the another one problem is the increase of the bobbin diameter that twines because the increase of bobbin diameter, alternately near and changing gradually by strand axial location of the solid wire of the yarn of laying of separating.This just periodically forms endless belt (zones), and they are upset the shape of package and make winding process complicated.This situation can by based on specific adjusting so that the motion frequency of reciprocating lever change gradually to prevent.
The existing solution that reciprocating lever drives is used cam mechanism usually.A kind of mechanism with constant lifting traverse has guaranteed the saw shape lifting traverse that reciprocating lever is basic, and the speed that is included in the dead point changes.The mechanism of the second stack can realize the slow parallel at dead point.Two kinds of mechanisms have all loaded and have caused that the reciprocating lever motion is necessary with joint efforts.Finish to the interference of endless belt or by the controlled change-speed box (variator) that usually is subjected to other cam mechanism control, perhaps finish by in the current supply circuit of driving motor, adding frequency transformer.The transmission gearbox that comprises these mechanisms only is positioned at a side of machine, so that long reciprocating lever is responsive to the formation of vibration.Along this reciprocating lever the diffusion of the longitudinal wave of deformation is arranged not only, also have this reciprocating lever because stand the bending in the center bearing pilot bearing and wave and the diffusion of the lateral wave that causes.In addition, wave and also cause friction force to increase.Laterally wave propagation velocity is less than longitudinal wave on the reciprocating lever, and the swing of reciprocating lever is usually very complicated.Therefore, the free-ended motion of reciprocating lever is different from the motion of itself and driver train connecting portion.
Clearly, restriction reciprocating speed and to make the complicated major cause of driver train of reciprocating lever be that huge deceleration and acceleration effect owing near the moving-mass dead point do not compensated the force of inertia that causes fully.
For the energy that absorbs the motional inertia quality and be used subsequently, used spring based on some devices of prior art.If this spring has better corresponding to the nonlinear characteristic of the necessary power of desired movement that reaches this reciprocating lever, then this method is favourable.Be difficult to guarantee this specific character at mechanical spring or gas spring.In some situations for cam mechanism unloading, use rubber draft gear or plastic bumper near the dead point to the reciprocating lever effect.These springs can cause the shock and vibration of this reciprocating lever, and their service life is also short.
In addition, thus the width that these device major parts can not be regulated the lifting traverse of reciprocating lever and be changed package on the bobbin.Reciprocating lever often stands huge pressure, need to correspondingly increase cross-sectional plane, and this further causes again the weight of feed rod to increase, and then increases undesirable force of inertia.Even in the sizable situation of the cross-sectional plane of reciprocating lever, swing also often causes having different routes in the lifting traverse of this reciprocating lever of diverse location of machine.
The objective of the invention is to eliminate or reduce at least substantially the shortcoming of prior art.
Summary of the invention
Be wrapped in the yarn reciprocator on the bobbin that is installed in the weaving loom operating unit winding mechanism, its principle is, on reciprocating lever and machine frame, apart from one another by ground two pairs of magnets are installed, wherein every a pair of magnet includes magnetostatic body and moving magnet, and the magnet of magnet centering is settled by identical polarity mode respect to one another, wherein magnetostatic body is installed on the machine frame, and moving magnet is installed on the described reciprocating lever.
Its favourable part is that the straight line that effectively absorbs reciprocating lever in the district of dead point reverses, the inertial mass energy of the stage accumulation reciprocating lever before the dead point, and after the dead point, discharge the startup operation that this energy is facilitated reciprocating lever.
If use a pair of magnetostatic body and the moving magnet that is positioned at reciprocating lever end on the machine, the pressure in the reciprocating lever is significantly reduced even all compensation.Thereby can unload significantly the load in the reciprocating lever or replace it with the light-weight parts that can only transmit pulling force.This has promoted the reduction of driver train live load effectively.
Can also utilize the suitable shape of magnetostatic body and moving magnet and arrange direction and the amplitude select their separating forces so that the driving of reciprocator only provide overcome whole reciprocator by dynamic resistance and make the yarn energy that deflection needs in the bobbin coiling.
If every a pair of magnet forms by the magnetostatic body of the installation of adjustable ground on the machine frame and the moving magnet that is installed on the reciprocating lever with fixed form, then this situation is favourable.
Can adapt to the variation of reciprocating lever dead center position by placing magnetostatic body, and direction and amplitude peak thereof that can the power of influence on reciprocating lever.
If magnetostatic body is attached on the machine frame in adjustable mode by the servomotor torque constant that is fixed on the frame, the output of this servomotor torque constant is that magnetostatic body is along the traveling priority of reciprocating lever, and the output block of servomotor torque constant was stablized after this traveling priority was finished, and then it is especially favourable.
If the control unit of the servomotor torque constant of magnetostatic body and definite reciprocating lever dead center position links, then it is more favourable.
If between magnetostatic body and moving magnet, settle shock absorber, also be favourable.
Shock absorber prevents contact possible between the magnet, and it has protected magnet from machinery like this.Advantageously, if at magnetostatic body with for example insert spring members between the servo-drive, disk spring for example, in case when reaching the limiting force between magnetostatic body and the moving magnet, it makes the magnetostatic body can travelling backwards, and prevents from contacting with moving magnet and/or magnetostatic body damages with impact or the reciprocating lever that moving magnet contacts with shock absorber in the caused reciprocating lever because of magnetostatic body.
In favourable arrangement, be provided with in its vicinity reciprocating lever axial location sensor along reciprocating lever.
If magnetostatic body is established the sensor of effective separating force numerical value, then also be favourable.
Position transduser by reciprocating lever can more accurate mode be monitored the Motor execution of reciprocating lever, and works when the change of magnetostatic body position thus, and in addition, separating force numerical value sensor also helps this.
If make the driver train that reciprocating lever generation straight line reverses comprise the servomotor torque constant of being controlled by the control unit of the dead center position of determining described reciprocating lever, and simultaneously they connect with the axial location sensor of reciprocating lever and the sensor and the magnetostatic body separating force sensor that act on the power in the reciprocating lever at least, and then this situation is favourable.
By relevant reciprocating lever position, the information that acts on the separating force of power in the reciprocating lever and magnet being sent to the control system of the servomotor torque constant of reciprocating lever driver train, can advantageously optimize the operation of mechanism, obtain thus the suitable motion of reciprocating lever.
Arrangement with the described magnetostatic body of the favourable part of carrying, moving magnet and reciprocating lever not only can be applied in the new reciprocator, also can be applied in the existing or old reciprocator with different reciprocating lever drivings.
The driver train of reciprocating lever can increase suitable mechanism by the rotating servo electrical motor and will rotatablely move and be transformed to straight-line motion and carry out, and perhaps advantageously carries out by having straight-line linear servomotor.
