Description
Technical field
The present invention relates on a kind of cutting machine floating roller mechanism more particularly to a kind of cutting machine unreel double floating roller mechanisms
And its closed loop control method.
Background technology
In cutting winds application field, for cutting parent roll circularity is poor, tension fluctuation is big, easy for small tension receiving coil material
The problems such as stretcher strain, seriously affects winding film roll quality, such as material tensile deformation, fold, scuffing, to road work after influence
Sequence produces, and notably causes product rejection.
Dancer main function on existing parting off unreeling machine is tension to be established on the material that slitting unreels, and protect
Unwinding tension stabilization is held, is fluctuated caused by simultaneous buffering parent roll out-of-roundness, ensures that parent roll releasing material is smooth, to ensure material
The quality requirements of road production process afterwards.
Such as the prior art 1（CN101519169B）In disclose a kind of floating roll device for splitting machine, use single floating
Dynamic roller mechanism, wallboard inside opposite position is vertically-mounted the linear guide, dancer both ends band boss circle spherical outside surface ball
Bearing be first installed on mounting plate after again in overall installation to the linear guide, enable dancer vertical up-or-down movement.
The prior art 1 is disadvantageous in that：In a first aspect, in the mechanical mechanism of single dancer, material only bypasses floating
Dynamic roller is primary, therefore the stroke up and down of single dancer is the 1/2 of undulate quantity, the poor synchronization of response action.
Second aspect, the material tension of single floating roller mechanism at a distance from floating roller fulcrum and pivot point, cylinder fulcrum with
The distance of pivot point, material are related with single dancer angle, cylinder pressure and cylinder area of section, are confined to cylinder most
Little trick air pressure can not possibly obtain the output of small tension receiving coil by reducing atmospheric pressure value sometimes, therefore pass through reduction in single dancer
Atmospheric pressure value is limited come the control program for obtaining small tension receiving coil.
The third aspect, single dancer cannot achieve weight balancing, only in the quiescent state since only there are one dancers
Additionally plus weight linear meter or reach static balancing by way of compensation cylinder equilibrium air pressure, and weight linear meter and atmospheric pressure compensating
There is certain error in mode, the static force that this error generates will act directly on material.
The fluctuation of fourth aspect, material tension depends primarily on the dynamic acceleration variation of dancer system, is transported in equipment
During row, the fluctuation up and down of dancer, since the quality of deflector roll and connecting rod itself exists, by Newton's second law it is found that meeting
Generate additional additional dynamic load.
Invention content
The present invention is in order to overcome cutting machine in the prior art to unreel bad response, tension control existing for single floating roller mechanism
Precision processed is low, static balancing is poor, the deficiency of dynamical balance feature difference, provides a kind of cutting machine and unreels double floating roller mechanisms,
Response is good, tension force precision is high, static balancing is good, dynamical balance feature is good.
To achieve the goals above, the present invention uses following technical scheme：
A kind of cutting machine unreels double floating roller mechanisms, including active dancer, driven dancer, cylinder and connecting rod, the active
Dancer is connected with active dancer swing arm, and the active dancer swing arm is swung around first rotating shaft, described in the cylinder driving
Active dancer swing arm is swung, and the driven dancer is connected with driven dancer swing arm, and the driven dancer swing arm is around the
The both ends of two shaft swings, the connecting rod are hinged with the active dancer swing arm and driven dancer swing arm respectively.
In double floating roller mechanisms provided by the invention, material bypasses active dancer and driven dancer respectively twice,
And active dancer and driven dancer use connecting bar each other, therefore 1/4 that the stroke up and down of dancer is undulate quantity, simultaneously
The synchronism that ensure that response action improves 1 times than single dancer.
Material tension and floating roller fulcrum at a distance from pivot point, cylinder fulcrum is at a distance from pivot point, material and
One dancer angle, material are related with the second dancer angle, cylinder pressure and cylinder area of section, in same mechanical ruler
When very little, same cylinder model, same pressure, double floating roller mechanisms provided by the invention can control more small tension receiving coil, if material around
When to cross the angle of dancer be vertical, then the tension force precision of double dancers can be increased to 1 times of single dancer.
The fluctuation of material tension depends primarily on the dynamic acceleration variation of floating roller mechanism, in equipment running process,
The fluctuation up and down of dancer, since the quality of dancer itself exists, by Newton's second law it is found that will produce additional add
Dynamic loading.In the case where not considering other factors, since the buffering capacity of single dancer is only 1/2 and unit of double dancers
The adjusting stroke of single dancer is double 2 times of dancers in time, and acceleration is also 2 times, therefore theory analysis, the tension of single dancer
Undulate quantity is at least 2 times of double dancers, in addition weight itself and existing static unbalance, through experimental test, fluctuates width
Degree reaches nearly 50%.And in double floating roll structures, double dancers equally exist dynamic additional load, but double dancers buffer
Amount is big, and adjusting floating is small, and the PID amplitudes of accommodation are shallow, and the acceleration of generation is small, integrated system error, through experimental test, fluctuating range
Only 10%.

Shaft and the line section of the swing arm of active dancer and active dancer tie point and second shaft and driven dancer swing arm
Parallel and equal with the driven line section of dancer tie point, the active dancer and the driven dancer are identical in quality.
Under active dancer and driven dancer self gravitation effect, the swing arm of active dancer and driven dancer swing arm
, direction equal to the amount of force of connecting rod is on the contrary, therefore this double floating roller mechanism in the quiescent state can with static balancing
It realizes weight balancing, stops at an arbitrary position, additional static force will not be generated to material.
As a preferred technical solution of the present invention, the active dancer swing arm and the driven dancer swing arm
Shape, size, quality all same, to eliminate the influence of the swing arm of active dancer and driven dancer swing arm gravity so that this is double
