Description

Technical Field

[0001] The present invention relates to a solventless compounding device, in particular to a multi-layer compounding method based on sequential lateral registration. Background Art

[0002] The multi-layer compounding machine is formed by connecting multiple units on-site at the customer's location. There are installation errors between the units, resulting in a deviation value of the center plane of each coating unit relative to the center plane of the compounding unit; the edge line of the surface of the leveling roller determines the coating position of the base material, but there is also a deviation value of the lateral center of the surface of the leveling roller of each coating unit relative to the center plane of its respective coating unit due to processing and installation errors. Due to the superposition of the above deviation values, there may be a large lateral deviation between the coating edges of each coated film during compounding. Currently, the traditional tape deviation correction methods and deviation correction devices are still used in multi-layer compounding machines. When the multi-layer compounding machine is started, the operator relies on adjusting the zero position of the detection photocells of each deviation corrector, and then horizontally adjusts the lateral position of the coated base material tape to achieve the purpose of ensuring that both sides of each unwinding tape adapt to the width direction of its respective coating layer and are aligned with the coating width direction of other unwinding base material tapes. There are problems such as difficult adjustment, slow speed, poor effect, and even inability to adjust the relative positions of multiple unwinding films well. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-layer compounding method based on sequential lateral registration, which can solve the problem of lateral registration in multi-layer tape compounding.

[0004] To solve the above technical problem, the technical solution of the present invention is: a multi-layer compounding method based on sequential lateral registration, including the following steps:

[0005] (S1) Detection:

[0006] Detect the deviation value E of the lateral center plane of each coating unit relative to the center plane of the compounding unit BJ ,

[0007] Detect the deviation value E of the lateral center of the coating surface of each leveling roller relative to the center plane of its respective coating unit FJ ,

[0008] Detect and collect the lateral deviation error △L of each unwinding tape fed back by each deviation correction component J ,

[0009] When the lateral center plane of the coating unit is at the drive end of the center plane of the compounding unit, the deviation value E BJ is taken as a positive value, otherwise it is taken as a negative value;

[0010] When the lateral center of the coating surface of the leveling roller is at the drive end of the center plane of its respective coating unit, the deviation value E FJ is taken as a positive value, otherwise it is taken as a negative value;

[0011] In the above codes, J is the serial number of the glue - applying unwind tape.

[0012] (S2) Operation:

[0013] Input the width W of each glue - applying unwind tape J and the width W of the non - glue - applying unwind tape N ,

[0014] Input the width F of each equalizing roller surface J ,

[0015] (S21) Calculate the unilateral allowance of the width of each glue - applying unwind tape with respect to the width of its respective equalizing roller surface:

[0016] C J =(W J - F J ) / 2

[0017] (S22) Calculate the distance of the transmission - end side line of each equalizing roller surface from the center plane of the composite unit:

[0018] D FJ = 0.5F J +E BJ +E FJ

[0019] (S23) Find the maximum value of D FJ Define it as the D of the farthest unwind tape FX , and the minimum value of D FJ Define it as the D of the nearest unwind tape FM :

[0020] D FX is Max[D F1 : D F(N-1)

[0021] D FM is Min[D F1 : D F(N-1)

[0022] (S24) Set the adjustment value of the tape edge position:

[0023] Let: Σ DF =(D FX - D FM ) = 0.5(F X - F M )+E BX +E FX - E BM - E FM

[0024] If Σ DF ≤2(C​​M -K)

[0025] Then take

[0026] △ X = 0.5 * Σ DF = 0.25(F X - F M ) + 0.5(E BX + E FX - E BM - E FM )

[0027] In the above formula: Σ DF is the distance difference between the maximum and minimum of the composite center line of the glue application margin at the driving end, that is, the maximum cumulative deviation;

[0028] F X , E BX , E FX , C FX are respectively the F FX corresponding to the maximum value D J , E BJ , E FJ , C J ,

[0029] F M , E BM , E FM , C FM are respectively the F FM corresponding to the minimum value D J , E BJ , E FJ , C J ,

[0030] C M is the smaller value corresponding to C FX and C FM ;

[0031] K is the minimum width allowance allowed when applying glue to the material tape, and the value is 1 - 2;

[0032] △ X is the inward lateral adjustment amount of the farthest unwind material tape to the center of the glue application surface of its uniform glue roller and the outward lateral adjustment amount of the nearest unwind material tape to the center of the glue application surface of its uniform glue roller. The adjustment amount refers to the difference between the asymmetric glue application position and the symmetric position of the unwind material tape to its uniform glue roller;

[0033] The adjustment values of the remaining glue application unwind material tapes are:

[0034] △ J = E BX + E FX - △ X - EBJ -E FJ

[0035] Lateral adjustment amount of non-glued unwind tape:

[0036] △ N = E BX + E FX - △ X

[0037] If Σ DF > 2(C M - K), the cumulative deviation is too large or the unilateral margin of the tape is too small, making it difficult to complete the adjustment. It is necessary to increase the unilateral margin of the tape or reduce the maximum cumulative deviation;

[0038] (S25) Verification of the actual unilateral margin of the unwind tape:

[0039] After adjusting the position of the unwind tape edge, the actual minimum unilateral margin of each unwind tape for its respective glue leveling roller is:

[0040] Farthest unwind tape: C XMIN = C FX - △ X

[0041] Nearest unwind tape: C MMIN = C FM - △ X

[0042] Any other unwind tape: C JMIN = C J - △ J

[0043] The above C XMIN 、C MMIN 、C JMIN should all be greater than K;

[0044] (S26) Calculate the zero position of each unwind deviation correction component. The zero position refers to the position when the deviation correction photocell is aligned with the non-deviating substrate edge or marking line, and is represented by the dimension Y from the deviation correction photocell to the center of the installed unit:

[0045] When using edge-following deviation correction:

[0046] Farthest unwind tape: Y X = 0.5W X + △ X

[0047] Nearest unwind tape: Y M = 0.5W M - △ X

[0048] Any other unwind tape: YJ = 0.5W J + △ J

[0049] Non - coated unwind tape: Y N = 0.5W N + △ N

[0050] When using line - following deviation correction:

[0051] Farthest unwind tape: Y X = D X + △ X

[0052] Nearest unwind tape: Y M = D M - △ X

[0053] Any other unwind tape: Y J = D J + △ J

[0054] Non - coated unwind tape: Y N = 0.5W N + △ N

[0055] In the above formula: W X 、W M are the widths of the farthest unwind tape and the nearest unwind tape respectively,

[0056] D X 、D M 、D J are the distances from the deviation - correction identification lines of the farthest unwind tape, the nearest unwind tape and any other unwind tape to the center of the tape width respectively;

[0057] (S3) Execute: The system analyzes and calculates the lateral adjustment amounts of each unwind tape to its sizing roller for aligning the centers of all tapes of the composite film and the lateral zero - position positions of each deviation - correction component, and the PLC centrally controls the movement of the motors for adjusting the zero - position positions of each deviation - correction component according to the calculation results so that the deviation - correction electric eyes reach the specified positions.

[0072] This description uses the applications of a four-layer compounding machine and a three-layer compounding machine to illustrate a multi-layer compounding method based on sequential lateral registration.

[0073] As Figure 1 shown, a four-layer compounding machine includes a frame.

[0074] As Figure 2 shown, in a three-layer compounding machine with another arrangement form, it includes a frame. Under the frame, a first coating unit 1, a second coating unit 2, and a compounding unit 3 are arranged in sequence. The first coating unit 1 includes a first unwinding unit 6, a first coating unit 11, and a first unwinding deviation correction component 15.

The compounding unit 3 includes a compounding unit 14, a winding unit 10, a third unwinding unit 8, and a third unwinding deviation correction component 17. The third unwinding unit 8 is a non-coated material coil unwinding unit.

[0075] As Figure 3As shown, the structures of the above-mentioned first unwind deviation rectifying component 15, second unwind deviation rectifying component 16, third unwind deviation rectifying component 17 and fourth unwind deviation rectifying component 18 are the same, and each includes a deviation rectifying controller 153, a deviation rectifying drive motor assembly and a deviation rectifying electric eye assembly. The deviation rectifying drive motor assembly is arranged between the wallboard of the coating unit and the wallboard of the corresponding unwind unit. The deviation rectifying electric eye assembly includes a deviation rectifying detection electric eye 1541, a lateral movement mechanism 1543 and a zero position adjustment motor 1542. The deviation rectifying detection electric eye 1541 is arranged on the lateral movement mechanism 1543 and is directly aligned with the material tape path.

[0076] As Figure 4 , 5 shown, the multi-layer composite method based on sequential lateral registration includes the following steps:

[0077] (S1) Detection:

[0078] Detect the deviation value E of the lateral center plane of each coating unit relative to the center plane of the composite unit 3 BJ ,

[0079] Detect the deviation value E of the lateral center of the coating surface of each leveling roller relative to the center plane of its respective coating unit FJ ,

[0080] Detect and collect the lateral deviation error △L of the unwind material tape feedback by each deviation rectifying component J ,

[0081] When the lateral center plane of the coating unit is at the driving end of the center plane of the composite unit 3, the deviation value E BJ is taken as a positive value, otherwise it is taken as a negative value;

[0082] When the lateral center of the coating surface of the leveling roller is at the driving end of the center plane of its respective coating unit, the deviation value E FJ is taken as a positive value, otherwise it is taken as a negative value;

[0083] In the above codes, J is the serial number of the coated unwind material tape;

[0084] (S2) Calculation:

[0085] Input the width W of each coated unwind material tape J and the width W of the non-coated unwind material tape N ,

[0086] Input the width F of the surface of each leveling roller J ,

[0087] (S21) Calculate the unilateral allowance of the width of each coated unwind material tape relative to the width of the surface of its respective leveling roller:

[0088] C J =(W J -FJ ) / 2

[0089] (S22) Calculate the distance from the transmission end side line of each equalizing roller surface to the central plane of the composite unit 3:

[0090] D FJ = 0.5F J +E BJ +E FJ

[0091] (S23) Find the maximum D FJ Define it as the farthest unwind tape D FX , the minimum D FJ Define it as the nearest unwind tape D FM :

[0092] D FX is Max[D F1 : D F(N-1)

[0093] D FM is Min[D F1 : D F(N-1)

[0094] (S24) Set the tape edge position adjustment value:

[0095] Let: Σ DF =(D FX -D FM ) = 0.5(F X -F M )+E BX +E FX -E BM -E FM

[0096] If Σ DF ≤2(C M -K)

[0097] Then take

[0098] △ X = 0.5*Σ DF = 0.25(F X -F M )+0.5(E BX +E FX -E BM -E FM )

[0099] In the above formula: Σ DF is the distance difference between the maximum and minimum of the transmission end glue - applying edge distance from the composite center line, that is, the maximum cumulative deviation;

[0100] F​​X , E BX , E FX , C FX are respectively the maximum value D FX corresponding to F J , E BJ , E FJ , C J ,

[0101] F M , E BM , E FM , C FM are respectively the minimum value D FM corresponding to F J , E BJ , E FJ , C J ,

[0102] C M is the smaller value of C FX and C FM corresponding to;

[0103] K is the minimum width allowance allowed when applying glue to the strip, with a value of 1 - 2;

[0104] △ X is the inward lateral adjustment amount of the farthest unwinding strip to the center of the glue - applying surface of the glue - equalizing roller and the outward lateral adjustment amount of the nearest unwinding strip to the center of the glue - applying surface of the glue - equalizing roller. The adjustment amount refers to the difference between the asymmetric glue - applying position and the symmetric position of the unwinding strip to its glue - equalizing roller;

[0105] The adjustment values of the remaining glue - applying unwinding strips are:

[0106] △ J = E BX +E FX -△ X -E BJ -E FJ

[0107] The lateral adjustment amount of the non - glue - applying unwinding strip:

[0108] △ N = E BX +E FX -△ X

[0109] If Σ DF > 2(C M -K), then the cumulative deviation is too large or the unilateral allowance of the strip is too small, making it difficult to complete the adjustment. It is necessary to increase the unilateral allowance of the strip or reduce the maximum cumulative deviation;

[0110] (S25) Verification of the actual unilateral allowance of the unwinding strip:

[0111] After adjusting the position of the edge of the unwound strip, the actual minimum unilateral allowance of each unwound strip for its respective sizing roller is:

[0112] Farthest unwound strip: C XMIN = C FX - △ X

[0113] Nearest unwound strip: C MMIN = C FM - △ X

[0114] Any other unwound strip: C JMIN = C J - △ J

[0115] The above C XMIN 、C MMIN 、C JMIN should all be greater than K;

[0116] (S26) Calculate the zero position of each unwinding deviation correction component. The zero position refers to the position when the deviation correction photocell is aligned with the non-deviating substrate edge or marking line, and is represented by the dimension Y from the deviation correction photocell to the center of the installed unit:

[0117] When using edge following deviation correction:

[0118] Farthest unwound strip: Y X = 0.5W X + △ X

[0119] Nearest unwound strip: Y M = 0.5W M - △ X

[0120] Any other unwound strip: Y J = 0.5W J + △ J

[0121] Non-coated unwound strip: Y N = 0.5W N + △ N

[0122] When using line following deviation correction:

[0123] Farthest unwound strip: Y X = D X + △ X

[0124] Nearest unwound strip: Y M = D M - △ X

[0125] Any other unwinding tape: Y J =D J +△ J

[0126] Non-adhesive unwinding tape: Y N =0.5W N +△ N

[0127] In the above formula: W X , W M , are the widths of the farthest unwinding tape and the nearest unwinding tape, respectively.

[0128] D X , D M , D J , are the distances from the marking lines of the farthest unwinding tape, the nearest unwinding tape and any unwinding tape to the center of its tape width;

[0129] (S3) Execution: The system analyzes and calculates the lateral adjustment amount of each unwinding material strip on its glue-distributing roller and the lateral zero position of each correcting component in order to align the centers of all material strips of the composite film, and the PLC centrally controls the movement of the zero position adjustment motor of each correcting component according to the calculation results so that the correcting electric eye reaches the specified position.

[0130] Figure 6 E is the deviation value of the horizontal center of the glue-spreading roller's glue-spreading surface from the center plane of each coating unit FJ The diagram shows the distances from the two sides of the rubber roller coating surface to the two adjacent wall panels. The difference between the two distances (X1-X2) is the deviation value E of the unit to which it belongs. FJ .

[0131] Figure 7 , 8 E is the deviation value of the lateral center plane of the coating unit relative to the center plane of the compounding unit BJ The measurement diagram of. In the figure, the processing surface 20 is reserved without painting at the place where the inspection ruler 21 is installed on each unit. The inspection ruler 21 is placed against the processing surface 20 of one unit, and the dial gauge base 22 is installed on the inspection ruler 21 at this position and zeroed. The dial gauge base 22 is installed at the place where there is a processing surface at the other end of the ruler. The dial gauge probe touches the processing surface of another unit to read the surface data. At least two places are inspected, and their data are used as the deviation value E of the center plane of the two wall panels and the two units. BJ .

[0132] After the zero position of the deflection correction electric eyes of each unit is adjusted, the material strips of the unwinding substrate to which it belongs will automatically follow the adjustment of the position in the width direction, so that each base material strip can achieve the purpose of ensuring that the two sides of each unwinding material strip are adapted to the width direction of their own coating layer, and also be aligned with the coating width direction of other unwinding base material strips. If the material strip unwound from the roll deflects in the width direction, the electric eye will feed back the signal to the deflection correction controller and instruct the deflection correction drive motor assembly to push the unwinding device to swing in the opposite direction for complete deflection correction.

[0135] The following example uses a four-layer composite machine to illustrate the calculation process:

[0136] (S1) Detection data: E B1 =1.5mm, E B2 =-1mm, E B3 =-0.5mm, E B4 =0mm;

[0137] E F1 = 0.5 mm, E F2 = -0.5 mm, E F3 = 0.5 mm;

[0138] (S2) Operation:

[0139] Input data: W1 = 910 mm, W2 = 906 mm, W3 = 906 mm, W4 = 908 mm,

[0140] F1 = 900 mm, F2 = 900 mm, F3 = 900 mm,

[0141] (S21) Calculate the unilateral allowance of the width of each glue-applying unwinding tape to the width of the respective glue-leveling roller surface:

[0142] C1 = (W1 - F1) / 2 = (910 - 900) / 2 = 5 mm

[0143] C2 = (W2 - F2) / 2 = (906 - 900) / 2 = 3 mm

[0144] C3 = (W3 - F3) / 2 = (906 - 900) / 2 = 3 mm

[0146] D F1 = 0.5F1 + E B1 + E F1 = 0.5 * 900 + 1.5 + 0.5 = 452 mm

[0147] D F2 = 0.5F2 + E B2 + E F2 = 0.5 * 900 - 1 - 0.5 = 448.5 mm

[0154] (S24) Set the adjustment value of the edge position of the strip:

[0155] Σ DF = (D FX - D FM ) = 452 - 448.5 = 3.5 mm

[0156] 2(C M - K) = 2*(3 - 1) = 4 mm, K takes 1

[0157] Σ DF <2(C M - K)

[0158] △ X = 0.5 * Σ DF = 0.5 * 3.5 = 1.75 mm

[0162] = 1.5 + 0.5 - 1.75 + 0.5 - 0.5 = 0.25

[0163] Adjustment amount of the fourth unwind strip:

[0164] △4 = E BX + E FX - △ X = E B1 + E F1 - △ X = 1.5 + 0.5 - 1.75 = 0.25

[0165] (S25) Verification of the actual unilateral margin of the unwound strip:

[0166] The farthest unwound strip: C 1MIN = C FX - △ X = C1 - △ X = 5 - 1.75 = 3.25

[0167] The nearest unwound strip: C 2MIN = C FM - △ X = C2 - △ X = 3 - 1.75 = 1.25

[0168] The third unwound strip: C 3MIN = C J - △ J = C3 - △ X = 3 - 1.75 = 1.25

[0169] After the position of the strip is adjusted, the actual unilateral margin of the unwound strip is greater than the selected value 1 of the K value.

[0173] Y2 = 0.5W2 - △ X = 0.5 * 900 + 1.75 = 448.25

[0174] Y3 = 0.5W3 + △ J = 0.5 * 900 + 0.25 = 450.25

[0175] Y4 = 0.5W4 + △4 = 0.5 * 900 + 0.25 = 450.25

[0176] When using line following deviation correction:

[0177] Y1 = D1 + △ X = D1 + 1.75

[0178] Y2 = D2 - △ X = D2 - 1.75

[0179] Y3 = D3 + △3 = D3 + 0.25

[0180] Y4 = D4 + △4 = D4 + 0.25

[0181] In the above formula, D1, D2, D3 and D4 are the distances of the color marks on each unwinding tape from the center of the width of the tape.
