Description
Technical field
The invention belongs to printing equipment technical field, it is related to a kind of printing machine tension control method, and in particular to Yi Zhongyin
Brush machine variable tension control method.
Background technology
Under conditions of prior art, in the printing process of printing machine, machine in lifting speed, the tension force of machine
Regulation is constant.And machine is on startup, it is necessary to overcome huge rotary inertia, accelerator could be completed, machine is from quiet
Only raising speed always produces substantial amounts of waste product to maximum speed, by taking 250m/min printing machine as an example, specifically, works as machine speed
For：A large amount of waste products can be produced during 0-60m/min, a small amount of waste product is produced during 60-250m/min.These waste products are all because to overcome
What rotary inertia was produced, this can cause the equipment of user to be raised using totle drilling cost.
But existing printing machine tension force, the regulated quantity of tension force is all fixed during lifting speed and constant speed
, because material volume most needs at a high speed to overcome huge rotary inertia from static accelerate to, therefore easily cause tension adjustment amount not
Foot, so as to cause adjustment delayed, easily produces waste product.If simply simply tuned up tension adjustment amount, in constant speed printing
During, system concussion is easily caused again so that system is unstable.Therefore in Up and down speeding, the best way is using song
The mode of line attenuation controls tension adjustment amount.It thus can perfectly solve the tension force control under the conditions of acceleration and deceleration and constant speed
System, efficiently reduces the generation of waste product, lowers machine use cost.
The content of the invention
It is an object of the invention to provide a kind of printing machine variable tension control method, solve and risen in the prior art in start
Tension adjustment amount is constant so as to cause the problem of a large amount of waste products are produced during reduction of speed.
The technical solution adopted in the present invention is that a kind of printing machine variable tension control method is entered to press speed
During row control, following functional relation is met：
P=-Alnv+P0+B (1)
In formula (1),
P represents tension adjustment amount,
V represents the speed of machine,
P0Represent the regulated quantity of tension force when machine reaches stable state；
A and B are adjusting parameter,
The relation of A and B between the two meets B=Aln (Vmax) (2),
In formula (2), VmaxFor the maximum speed of machine；
And, A=0.023mr2 (3)
In formula (3), m is the quality of material volume, and r is the radius of material volume.
The features of the present invention is also resided in,
A span is usually 0<A<20.
The beneficial effects of the invention are as follows, the disadvantage that tension adjustment amount remains unchanged when changing conventional printing machine acceleration and deceleration,
Using acceleration and deceleration curves tension adjustment mode, in equipment initial start stage, machine is to overcome huge rotary inertia to need increasing tension
The dynamics of regulation, and after machine run gets up, then normal tension force is reverted to, it is processed as, can efficiently reduces useless
Product, improve the performance of printing machine, are the same reasons when machine down, otherwise, the performance of equipment is improved, is reduced
Equipment uses totle drilling cost.
Brief description of the drawings
Fig. 1 is the comparison diagram of existing conventional tensile adjustment amount and tension adjustment amount of the present invention；
Fig. 2 be the printing machine variable tension control method of the present invention when A takes different value, to the decay of tension adjustment amount and
The comparison diagram that initial value is impacted.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of printing machine variable tension control method, when being controlled to press speed, meets following function and closes
System：
P=-Alnv+P0+B (1)
In formula (1), P represents tension adjustment amount,
V represents the speed of machine,
P0Represent the regulated quantity of tension force when machine reaches stable state；
A and B are adjusting parameter,
The relation of A and B between the two meets B=Aln (Vmax) (2)
In formula (2), VmaxFor the maximum speed of machine；
Wherein, the rate of decay and initial value of A energy change tension force adjustment amount, A=0.023mr2, wherein, m is the matter of material volume
Amount, r is the radius of material volume.A value is relevant with the quality and radius of material volume used in printing machine, material volume quality is bigger, radius more
Greatly, then A value is bigger.In actual production process, user can be adjusted according to the service condition of material volume, to reach
Best effects.Usual A span may be set in 0<A<20, A values are bigger, then the tension adjustment amount P rate of decay is faster,
Variable tension initial value is bigger.
The present invention a kind of printing machine variable tension control method, its carry out tension adjustment when curve as shown in figure 1, its
Middle curve P1Tension variation figure when representing that tension force is adjusted according to the method for the present invention, and P0Curve, is represented existing conventional
Tension curve adjusts curve, it can be seen that the method for the present invention is when carrying out tension adjustment, in low speed, tension force
Adjustment amount can reach greatly 80 very much, and now tension force response is rapid, is gradually reduced with the rising adjustment amount of speed, when machine speed
When degree reaches 250M/min, the tension adjustment amount of machine reaches normal value, and machine also enters stable state.
When Fig. 2 is that A takes different value, the influence of the rate of decay and initial value to tension adjustment amount；
In figure, P3When representing A=10, tension adjustment amount is with the increased variation tendency of speed, P2When representing A=20, tension force is adjusted
Whole amount is with the increased variation tendency of speed.It can be seen that A values are bigger, P initial value is bigger, and the P rate of decay
It is bigger.
, can be according to adjustment A values the need for production, to allow machine to be optimal effect during specifically used
Really.For example：, can more effectively gram the coil diameter of material volume is larger or during larger quality of material volume, can suitably increase A numerical value
The influence that rotary inertia is caused to machine chromatography is taken, to reach more preferable effect.
