As an embodiment, wherein, in foundation, the step of film curve point computation model may include that
According to the flow process of film on Film laminating apparatus, upper film curve is divided into sync section, round and smooth node, high regime,
Braking section and ending segment；
Set up each section of upper conversion between film curve point and synchronization length, film length and upper film high speed ratio respectively
Relational expression.
In one embodiment, conversion relational expression may include that
Sync section:
Initial value: x [0]=0, y [0]=0；
Synchronizing intermediate point: y [1]=W1, x [1]=W1/K, 0 ＜ W1 ＜ Z1, Z1 is synchronization length, and K is machinery
Synchronization factor；
Synchronize end point: y [2]=Z1, x [2]=Z1/K；
Round and smooth node:
Y [3]=y [2]+W2, x [3]=W2/K+X [2], 3mm ＜ W2 ＜ 10mm；
High regime:
High speed transition point: y [4]=y [3]+W3, x [4]=x [3]+(y [4]-y [3])/((H+1)/2)/K,
0 ＜ W3 ＜ Z2-W4-y [3], Z2 are film length, and H is upper film high speed ratio, 150mm≤W4≤170mm；
High speed end point: y [5]=Z2-W4, x [5]=x [4]+(y [5]-y [4])/H/K；
Braking section:
First deceleration point: y [6]=T1, x [6]=x [5]+(y [6]-y [5])/R1/K；
Second deceleration point: y [7]=T2, x [6]=x [6]+(y [7]-y [6])/R2/K；
3rd deceleration point: y [8]=Z2, x [8]=x [7]+(y [8]-y [7])/0.9/K；
Wherein, 2.6 ＞ R1 ＞ R2 ＞ 0.9, Z2 ＞ T2 ＞ T1 ＞ y [5]；
Ending segment:
Terminate initial point: x [9]=350, y [9]=Z2；
Terminate intermediate point: x [10]=W5, y [10]=Z2,350 ＜ W5 ＜ 360；
Terminate end point: x [11]=360, y [11]=Z2.
As shown in Figure 4, as a example by three row's beverage bottles carry out wrapping up in film, the sync section of upper film curve is corresponding to film
Z1 section, the round and smooth node of upper film curve is corresponding to the U point of film, and the high regime of upper film curve is corresponding to the G of film
Section, the braking section of upper film curve is corresponding to the W4 section of film；The ending segment of upper film curve is to allow Film laminating apparatus confirm
The upper film in this cycle terminates, only main axis, is coaxially just complete work, therefore, knot at braking section
Bundle section is not corresponding to certain part of film.
For sync section, that section pushed down at package object is sync section, a length of Z1, and 0 arrives same step-length
Between degree point, any point can serve as synchronizing the y value of intermediate point, in order to reach to synchronize purpose, this section
Curve ratio is y: x=mechanical synchronization COEFFICIENT K.In view of the size of the most targeted various package objects, with
Step-length degree all can be more than certain length, and such as 30mm, therefore, for targeted various package objects
Size, intermediate point y [1]=W1 generally take a common value, such as W1 can in 0 to 30mm value.
For round and smooth node, according to the characteristic of curve, can be to change when curve ratio changes
Node is as the roundest and the most smooth node, and the round and smooth node terminating to arrange afterwards in synchronization length is precisely in order to make up
The characteristic that curve is the roundest and the most smooth, prevent synchronize end point as the roundest and the most smooth node, to ensure " same to step-length
Degree " before proportionate relationship.Therefore, the y [3] of round and smooth node herein is relative to the y [2] synchronizing end point
Distance W2 increased, should be greater than the smallest circle slippery of the curve equal to Film laminating apparatus, and W2 value is the biggest, then bent
The braking section of line is the longest, just influences whether the length of the high regime of back segment, and therefore the optimal value of W2 is upper
The value of the curve smallest circle slippery of film machine.In actual applications, W2 takes 5mm, can meet current difference
The curve of model Film laminating apparatus the roundest and the most smooth.
For high regime, first the y [5] of height end point is according to the long Z2 of film and the required long W4 of deceleration film
Carry out value, y [5]=Z2-W4, during upper film, coaxially can not slow down too fast, it is therefore desirable to one section
Distance is slowed down, but braking section is long, can affect again operating efficiency, comprehensive different model Film laminating apparatus, subtract
The preferable value scope of the speed long W4 of film is [150mm, 170mm], and wherein 160mm is optimum value.In order to
Steadily high regime, devises high speed intermediate point, and in (y [3], y [5]), arbitrary value can serve as high speed intermediate point
Y [4].It addition, in order to avoid occurring that upper membrane process forgets about it bottle phenomenon, upper film high speed ratio H have to
More than 2.6；It addition, also note that the x [8] of the 3rd deceleration point next can not be more than or equal to 350, therefore, originally
Designer too increases step and carries out pointing out to prevent from makeing mistakes；In debugging, commissioning staff is through adjusting H
Value adjusts the situation of film.
For braking section, this interval is to steadily slow down so that carrying whole films, needs below satisfied
Relation: y [5] ＜ y [6] ＜ y [7] ＜ y [8]=film length Z2, upper film high speed ratio H ＞ decel slope R1 ＞ decel slope
R2 ＞ decel slope 0.9.Due to the long W4 of deceleration film the most all in [150mm, 170mm], the design people
Y [6] and y [7] has been distinguished a preferably value formula, the y [6] of the first deceleration point and the y [5] of high speed end point
Distance be 50mm, i.e. y [6]=y [5]+50mm, the y [7] of the second deceleration point with the distance of the end of film are
50mm, i.e. y [7]=Z2-50mm.If decel slope becomes the relation that equal difference is successively decreased, i.e. R1-R2=R2-0.9,
Then run slowly more smooth steady.Wherein, R1=2.5, R2=1.7 are optimal value.It addition, this interval knot
Bundle, film is all carried.
For ending segment, the most all carry to this interval film, y [9]=y [10]=y [11]=film length, but, for
This cycle upper film terminates the upper film in the lower cycle of carrying out, the cycle of 0-360 ° of main shaft to allow Film laminating apparatus confirm
The width inside leaving 10 degree confirms.The x [10] terminating intermediate point can take arbitrarily in (350,360)
Value.It addition, the x [8] of the 3rd deceleration point is necessarily less than 350 in braking section, i.e. braking section must be at main shaft
Complete within 0-350 °.
In conjunction with above-mentioned analysis, for the Film laminating apparatus of current different model, W1, W2, W3, W4, W5,
R1, R2, T1, T2 all can carry out identical concrete value or physical relationship formula.
Use the Film laminating apparatus of same concrete model, come for various sizes of package object, mechanical synchronization COEFFICIENT K
Also it is confirmable.
Therefore, film on various sizes of package object is carried out by the Film laminating apparatus of the same concrete model of use, all
W1, W2, W3, W4, W5, R1, R2, T1, T2, K can be set in advance.
Owing in actual applications, the most all various sizes of package object can be entered at the Film laminating apparatus of same
Film on row, therefore, all can arrange W1, W2, W3, W4, W5, R1, R2, T1, T2, K, so
Rear open synchronization length Z1, film length Z2 and upper tri-parameters of film high speed ratio H, allow commissioning staff according to
Different package objects is filled in；Therefore it may only be necessary to upper film high speed ratio H is adjusted by commissioning staff
Carry out debugging film, determine required upper film high speed ratio H according to the upper film effect of debugging, thus realize
Final upper film.Therefore, the present invention greatly reduces the debugging time of curve during debugging, does not also want
Ask commissioning staff to understand the characteristic of curve, reduce the requirement to commissioning staff, be especially advantageous for debugging.
When the Film laminating apparatus of specifically used mechanical synchronization COEFFICIENT K=1.4817, respectively to W1, W2,
W3, W4, W5, R1, R2, T1, T2 have done and have defined in detail below, W1=17K, W2=5mm,
W3=(Z2-W4+y [3])/2, W4=160mm, W5=353, T1=y [5]+50mm, T2=Z2-50mm,
R1=2.5, R2=1.7.
As it is shown in figure 5, combine above-mentioned analysis, upper film high speed ratio H is greater than 2.6 just will not forget about it bottle,
But excessive there will be curve point contradiction and correct curve can not be formed, therefore, below scheme is set: complete
After step 20 and before entering step 30, it is also possible to include step 20 ':
If x [8] >=350, then point out, and return step S20.
