In the upper film control method of above-mentioned Film laminating apparatus, by arranging upper film curve point computation model, commissioning staff is only needed to input synchronization length, film length, patrix high speed ratio three parameters, and in actual applications, synchronization length can be carried out defining concrete numerical value according to the size of package object and in conjunction with experience by operating personal, film length can directly define concrete numerical value according to the size of package object, namely synchronization length and film length can carry out a definite value according to the size of package object and need not change, only need carry out adjustment to debug upper film to patrix high speed ratio, effect according to the upper film of debugging determines required patrix high speed ratio, thus realize correct upper film.Therefore, the present invention greatly reduces the burn in period of curve in debug process, does not also require that commissioning staff understands the characteristic of curve, reduces the requirement to commissioning staff, be very beneficial to debugging.
As an embodiment, wherein, in foundation, the step of film curve point computation model can comprise:
According to the flow process of patrix machine patrix, 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 film curve point and synchronization length, conversion relational expression between film length and patrix high speed ratio respectively.
In one embodiment, conversion relational expression can comprise:
Sync section:
Initial value: x [0]=0, y [0]=0;
Synchronous intermediate point: y [1]=W1, x [1]=W1/K, 0 < W1 < Z1, Z1 is synchronization length, and K is mechanical synchronization coefficient;
Synchronous 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 point of transition: y [4]=y [3]+W3, x [4]=x [3]+(y [4]-y [3])/((H+1)/2)/K, 0 < W3 < Z2-W4-y [3], Z2 is film length, H is patrix 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 last point: x [11]=360, y [11]=Z2.
As shown in Figure 4, carry out wrapping up in film for three row's beverage bottles, the sync section of upper film curve corresponds to the Z1 section of film, and the round and smooth node of upper film curve corresponds to the U point of film, the high regime of upper film curve corresponds to the G section of film, and the braking section of upper film curve corresponds to the W4 section of film; The ending segment of upper film curve be allow Film laminating apparatus confirm the upper film in this cycle terminates, only have main axis, coaxially just finish the work at braking section, therefore, ending segment does not correspond to certain part of film.
For sync section, that section pushed down at package object is sync section, and length is Z1, and between 0 to synchronization length point, any point can as the y value of synchronous intermediate point, and in order to reach synchronous object, the curve ratio of this section is y:x=mechanical synchronization COEFFICIENT K.In view of at present for the size of various package objects, synchronization length all can be greater than certain length, such as 30mm, therefore, for for the size of various package objects, intermediate point y [1]=W1 gets a common value usually, such as W1 can in 0 to 30mm value.
For round and smooth node, according to the characteristic of curve, can using the node changed as automatically round and smooth node when curve ratio changes, the round and smooth node arranged after synchronization length terminates is just in order to make up the automatically round and smooth characteristic of curve, prevent synchronous end point as automatically round and smooth node, to ensure the proportionate relationship before " synchronization length ".Therefore, the distance W2 that the y [3] of round and smooth node herein increases relative to the y [2] of synchronous end point, the smallest circle slippery of the curve of Film laminating apparatus should be more than or equal to, W2 value is larger, then the braking section of curve is longer, will have influence on the length of the high regime of back segment, therefore the best value of W2 is the value of the curve smallest circle slippery of Film laminating apparatus.In actual applications, W2 gets 5mm, can meet the automatically round and smooth of the curve of current different model Film laminating apparatus.
For high regime, first the y [5] of height end point carries out value according to the long Z2 of film and the required long W4 of deceleration film, and y [5]=Z2-W4, in the process of upper film, coaxially can not slow down too fast, therefore need a segment distance to slow down, but braking section is long, can work efficiency be affected again, comprehensive different model Film laminating apparatus, the better value scope of the long W4 of deceleration film is [150mm, 170mm], and wherein 160mm is optimum value.In order to steady high regime, devise high speed intermediate point, in (y [3], y [5]), arbitrary value can as the y of high speed intermediate point [4].In addition, in order to avoid occurring that upper membrane process forgets about it bottle phenomenon, patrix high speed ratio H must be greater than 2.6; In addition, also notice that the x [8] of the 3rd deceleration point next can not be more than or equal to 350, therefore, the design people too increases step and carries out pointing out to prevent from makeing mistakes; In debugging, commissioning staff is exactly the situation being adjusted upper film by adjustment H value.
For braking section, this interval is to carry out steadily slowing down so that the whole film of conveying, relation below demand fulfillment: y [5] < y [6] < y [7] < y [8]=film length Z2, patrix high speed ratio H > decel slope R1 > decel slope R2 > decel slope 0.9.Because the long W4 of deceleration film is usually at [150mm, 170mm] in, the design people has distinguished a preferably value formula to y [6] and y [7], the y [6] of the first deceleration point is 50mm with the distance of the y [5] of high speed end point, i.e. y [6]=y [5]+50mm, the y [7] of the second deceleration point is 50mm with the distance of the end of film, i.e. y [7]=Z2-50mm.If the relation that decel slope becomes equal difference to successively decrease, i.e. R1-R2=R2-0.9, then run slowly more smooth steady.Wherein, R1=2.5, R2=1.7 are best value.In addition, this interval end, film is all carried.
For ending segment, all carry to this interval film, y [9]=y [10]=y [11]=film length, but, confirm that in order to allow Film laminating apparatus this cycle upper film terminates the upper film in the lower cycle of carrying out, the width leaving 10 degree within the cycle of 0-360 ° of main shaft confirms.The x [10] terminating intermediate point can get arbitrary value in (350,360).In addition, in braking section, the x [8] of the 3rd deceleration point must be less than 350, and namely braking section must complete within the 0-350 of main shaft °.
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, carry out the package object for different size, mechanical synchronization COEFFICIENT K is also confirmable.
Therefore, use the Film laminating apparatus of same concrete model the package object of different size carried out on film, all W1, W2, W3, W4, W5, R1, R2, T1, T2, K can be set in advance.
Due in actual applications, usually all can on the Film laminating apparatus of same carries out the package object of different size film, therefore, capital arranges W1, W2, W3, W4, W5, R1, R2, T1, T2, K, then open synchronization length Z1, film length Z2 and patrix high speed ratio H tri-parameters, allow commissioning staff fill according to different package objects; Therefore, only need commissioning staff to carry out adjustment to debug upper film to patrix high speed ratio H, determine required patrix high speed ratio H according to the upper film effect of debugging, thus realize final upper film.Therefore, the present invention greatly reduces the burn in period of curve in debug process, does not also require that commissioning staff understands the characteristic of curve, reduces the requirement to commissioning staff, be very beneficial to debugging.
When the Film laminating apparatus of concrete use mechanical synchronization COEFFICIENT K=1.4817, respectively following concrete definition is done to W1, W2, W3, W4, W5, R1, R2, T1, T2, 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 shown in Figure 5, in conjunction with above-mentioned analysis, patrix high speed ratio H is greater than 2.6 just can not forget about it bottle, but excessively there will be curve point contradiction and correct curve can not be formed, therefore, following scheme is set: after completing steps 20 and before entering step 30, can also step 20 be comprised ':
If x [8] >=350, then point out, and return step S20.
This step 20 ' prompting, can be the interface presenting prompting on operation interface, also can be control relative alarm device to carry out alarm.
The present invention also provides a kind of Film laminating apparatus, and this patrix machine carries out patrix by the upper film control method of the Film laminating apparatus of above-mentioned any embodiment, is convenient to very much debugging.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
