The actual time line speed signal that material comes out；
The real-time coil diameter signal of coiled strip on slip shaft is detected, the real-time coil diameter signal that this is detected is supplied to PLC；
Under conditions of known actual time line speed signal and real-time coil diameter signal, PLC controls unwinding motor and drives slip shaft
Operating, makes the revolving speed S < V/(D* π of slip shaft) (wherein: S revolving speed, V are real-time linear velocity, and D is to be scaled coil diameter directly
Diameter)；
And under conditions of known real-time coil diameter signal, PLC controls control air source equipment to adjust center in slip shaft
The air pressure size of air bag；
The relatively fixed roller of dancer floats, and cylinder sets the big of constant air pressure in cylinder by air pressure regulator adjustment
It is small, make cylinder action in power on dancer slightly larger than power of the material effects on dancer.
Air bag pressure size and real-time coil diameter size are positively correlated proportionate relationship in adjustment slip shaft, the bigger supply cunning of coil diameter
The air pressure of air bag is bigger in deviation shaft, with coil diameter become smaller supply the air pressure of air bag in slip shaft will be under change.
The effect reached by slip shaft will not be pulled off so that material (i.e. coiled strip) is stretched.Its material can be according to cunning
The slippage characteristic of deviation shaft so that the revolving speed of material achieved the effect that according to slippage principle with host it is synchronous.The direct torque of slippage,
Control air source equipment is the air bag being supplied to gas source inside slip shaft, air bag pressure size and outside by slippage axis center
Diameter detects obtained value size and reaches a corresponding positive correlation proportionate relationship, and material coil diameter is bigger, air bag in slip shaft
Air pressure is bigger, and material coil diameter is smaller, then air bag pressure is smaller in slip shaft, to control the identical tension effect of material.Material
Surface tension as built in being slip shaft friction plate or fricting strip through its (material) tension of central balloon pressure control.
Due to the mechanical property of slip shaft itself, it is however generally that 30 ms/min of slip amount on-line velocity or so, slippage
Amount is too big, and slip shaft easy to damage, slip amount is too small, and tension precision is uncontrollable, so for the slippage or one for guaranteeing an amount speed
The slippage of certainty ratio, under conditions of known real-time linear velocity and material coil diameter, PLC internal calculation is that a fixed speed is sliding
Poor or a certain proportion of slippage.For example, in known real-time linear velocity V, real-time coil diameter signal (such as diameter) D, then normally
Situation motor driven slide-bar axis revolving speed S '=V/(D* π) (do not consider reduction ratio in the case of), in view of slip amount, it is however generally that,
It can will consider that slip amount slides unwinding motor driving by a fixed speed difference or a certain proportion of speed difference, PLC
Deviation shaft revolving speed S1, which is less than, transfers S '=V/(D* π), it is exemplified below two kinds of PLC control unwinding motor driving slip shaft revolving speed S1:(1):
(y refers to a fixed velocity amplitude, also referred to as slip amount to unwinding motor revolving speed S1=(V-y)/(D* π), it is however generally that 10-30
It is set within the scope of m/min)；Alternatively, (2): S1=(V/(D* π)) * x(x be a fixed coefficient, slippage can also be referred to as
Amount, x are generally less than 1, usually select between 0-1)；Or other modes.
Unreel material receiving mechanism at least have there are two unwinding device be respectively used to place old material (for being unreeled before splicing) and
New material (for unreeling after splicing), each unwinding device all have slip shaft, and slip shaft is provided with unwinding motor and gas source control
Device, unwinding motor are driven slip shaft rotation, and control air source equipment controls in slip shaft (specially internal air bag) air pressure
Size.Switch between unwinding device for change of lap, unwinding device carries out splicing in material-receiving device.
Cylinder is connected to air pressure regulator, and the size of constant air pressure in setting cylinder is adjusted by air pressure regulator,
Dancer fixed roller movable (floating) setting, cylinder action relatively are slightly larger than material effects on dancer to the power on dancer
Power (implying that the power floated needed for dancer is slightly larger than the tension of material itself).When working condition, the material of unwinding device out
Arrangement is wound around on dancer and fixing roller by material, the air pressure size (being set as steady state value) of adjustment setting cylinder, after setting
Cylinder will act on to dancer constant size power, adjustment set the power than material effects to the power of dancer bigger, Neng Gourang
Cylinder just separates dancer with fixing roller, is limited using the travel of cylinder or floating position-limiting device in addition is arranged (such as
Limited block) limit dancer moving range.When splicing, splicing occurs before floating buffer device and from one
Unwinding device changes to another unwinding device, the unwinding motor emergency stop of a corresponding slip shaft, another slip shaft is put
Volume motor suddenly open, this stop out between have the time difference, cause material tension moment to become larger, influence subsequent printing effect and
Loss；The buffering tension that material moment becomes larger at this time can be offset by floating buffer device, dancer is in cylinder homeostatic process
Lower movement, the material to export after floating buffer device provides stable tension, while the movement of dancer is also to material
It carries out storage and release meets postorder host (the gold stamping mechanism of such as printing machine) and do not shut down work；When floating buffer device it
After preceding splicing is stablized, dancer reset movement under cylinder homeostatic process.
Splicing tension control is unreeled for embodiment:
1, the actual time line speed signal that the real-time linear velocity of detection host or host provide is to PLC；
2, the corresponding apparatus for detecting diameter detection signal of material on A slip shaft is to PLC；
3, PLC controls control air source equipment to adjust the air pressure size of slip shaft central balloon, i.e., of controllable material
Power size can also carry out the fine tuning of Tensity size in process of production；
4, then postorder host-initiated, in starting production process, the actual speed of slip shaft linear velocity more real-time than host
Required revolving speed is slow, and there are a slip amount, Tensity size needed for material actually the friction plate built in slip shaft or rubs
The frictional force of rub piece carrys out the torque of brake material, and the frictional force of friction plate or fricting strip is according to the central balloon in slip shaft
Air pressure size be adjusted；
5, the air pressure size of dancer cylinder air pressure is adjusted, generally by after the material tension after setting, then adjusts floating
Roller cylinder air pressure；When adjusting cylinder air pressure, so that cylinder action is slightly larger than material effects on dancer to the power of dancer
Power；Its object is to when manually or automatically reloading, material on A, B slip shaft, the fluctuation of splicing moment, by dancer institute
It absorbs；
6, can be in another prepared axis after tension is set --- material is prepared in advance on B slip shaft, by apparatus for detecting diameter
It is corresponding to be adjusted to right above material, start to detect coil diameter size in real time, and the material on B slip shaft is preparatory in material-receiving device
It is ready to, to subsequent splicing；
7, start splicing, in the moment of splicing, the corresponding motor of A slip shaft will stop working, the corresponding motor of B slip shaft
The diameter signal arrived according to real-time linear velocity and real-time detection exports a rotary speed instruction after operation, starts work, this stops,
One open between time difference for generating, cause the tension moment of material to become larger to be absorbed by dancer, after splicing is normal, float
