Description

Technical Field

[0001] This invention relates to the field of composites, and in particular to a method for lateral registration control in multilayer solvent-free composite equipment. Background Technology

[0002] In the process of laminating two or more layers of film, each unwound material belt is equipped with a set of correction devices. Traditionally, the correction devices are separate and the alignment of the composite film is completed manually. Moreover, the operation must be carried out while the machine is running. The adjustment process causes a waste of time and composite products. Especially in the case of multi-layer lamination, the alignment operation of the substrate is more difficult, resulting in greater waste. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-layer composite transverse alignment control method based on a unified reference. Before the machine is started, the base material strips are aligned with each other using the unified reference center. The alignment effect of the material strips is good, saving time, reducing the formation of defective products, and lowering the technical level requirements for operators.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a multi-layer composite lateral registration control method based on a unified benchmark, comprising the following steps:

[0005] 1) In a laminating machine with a maximum number of composite layers of N (N≥2), the feeding direction of the base material strip is defined as longitudinal, and the width direction of the base material strip is defined as transverse; the center line of the inner side of the wall panel group of the laminating machine is selected as the unified transverse reference line of the laminating machine, and the unified transverse reference line of the laminating machine is used as the common center line of the transverse position of all base material strips and each adhesive layer, that is, the zero line of the calculated edge line or the marking line of each base material strip;

[0006] 2) During the installation of the laminating machine, control the lateral deviation E of the centerline of the inner side of each coating unit and the wall panel assembly of each laminating unit relative to the unified lateral baseline of the laminating machine. FI The deviation between the centerlines of the inner sides of all unit wall panels shall not exceed 0.2 mm, and the deviation between them shall not exceed 0.5 mm.

[0007] In the above formula, I represents the serial number of the unit, I∈[1,(n-1)], and n is the total number of units;

[0008] 3) Control the lateral position and working width of each glue-coating roller to ensure that the lateral deviation of the center line of its coating area relative to the center line of the inner side of the wall panel group of its coating unit does not exceed 0.2 mm;

[0009] The working surface width F of the leveling roller I =W T

[0010] Glue application width W G =F I+2

[0011] In the above formula, W T F represents the width of the printed image on the printing substrate. I The upper deviation is 0.2 mm and the lower deviation is 0.1 mm; I represents the serial number of the coating unit, I∈[1,(N-1)], N is the number of composite layers;

[0012] A web-aligning probe is used to detect and track the edge lines or color mark lines of the base material or printed film. The detection accuracy of the web-aligning probe reaches the 0.01 mm level. The web-aligning probe is mounted on a laterally movable slide driven by a motor via a ball screw. The motion accuracy of the slide with the web-aligning probe is also at the 0.01 mm level. The zero-position value of the motor is adjusted so that the photoelectric sensor of the web-aligning probe is aligned with the center line of the unit it is located in.

[0013] 5) Calculate the lateral position coordinates (Y) of the detection center line of each substrate material with a correction probe relative to the unified lateral baseline for composite films of different widths. I :

[0014] When the substrate is a printed film, Y P =D

[0015] When the substrate is a non-printable film, Y I =0.5W I

[0016] In the above formula, D is the distance W from the cursor line on the printing film substrate to the center line of the printed image. I W is the width of the I-th non-printed substrate strip. I =W T +K1; K1 is the substrate width coefficient, K1=4~6 mm, which is selected by the stability of the laminating machine and the length of the material belt path; I∈[1,(N-1)], N is the number of composite layers;

[0017] 6) The calculated lateral position coordinates of the detection center line of each base material strip correction probe are transmitted as the lateral movement increment of the slider to the position control motor of each correction probe. The position control motor drives the lead screw to move, and the lead screw drives each correction probe to the detection position. When the machine is started, each unwound base material strip is corrected with the detection center line as the correction target position.

[0018] As an improvement, the laminating machine includes a coating unit consisting of at least two coating units and an unwinding unit, and a laminating unit consisting of a laminating unit and a rewinding unit.

[0019] As an improvement, ultrasonic sensors, photoelectric sensors, or CCD camera elements are selected as sensors for each correction probe, depending on the type of substrate.

[0020] The beneficial effects of this invention compared to the prior art are:

[0021] Before starting the machine, a common and unified benchmark for the composite substrate was established, which automatically completed the alignment of the base material strips of two or more layers before starting the machine. This ensured that the base material strips were aligned with each other around the unified benchmark center, resulting in good alignment of the material strips, saving time, reducing the formation of defective products, and lowering the technical level requirements for operators.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a four-layer solventless laminating machine includes, from left to right, a first coating unit 1, a second coating unit 2, a third coating unit 3, and a laminating unit 4. The first coating unit 1 includes a first wall panel, a first unwinding unit 5, a first coating unit 10, and a first web-aligning probe assembly 15. The second coating unit 2 includes a second wall panel, a second unwinding unit 6, a second coating unit 11, and a second web-aligning probe assembly 16. The third coating unit 3 includes a third wall panel, a third unwinding unit 7, a third coating unit 12, and a third web-aligning probe assembly 17. The laminating unit 4 includes a fourth wall panel, a fourth unwinding unit 8, a rewinding unit 9, a first laminating unit 13, a second laminating unit 14, and a fourth web-aligning probe assembly 18.

[0027] like Figure 2 As shown, the registration method involves: center line 101 of the working area of ​​the first leveling roller, center line 102 of the inner side of the wall panel group of the first coating unit, detection center line 103 of the first correction probe, unwinding of the first substrate 104, center line 201 of the working area of ​​the second leveling roller, center line 202 of the inner side of the wall panel group of the second coating unit, detection center line 203 of the second correction probe, unwinding of the second substrate 204, center line 301 of the working area of ​​the third leveling roller, center line 302 of the inner side of the wall panel group of the third coating unit, detection center line 303 of the third correction probe, unwinding of the third substrate 304, take-up roll 401, center line 402 of the inner side of the wall panel group of the laminating unit, detection center line 403 of the fourth correction probe, and unwinding of the fourth substrate 204.

[0028] like Figure 3 As shown, the working surface width F of the coating roller is... I=Printing width of the printed image on the printing substrate W T Glue application width W G =F I +2, width of non-printed substrate W I =W T +K1, K1 = 4~6 mm, selected based on the stability of the laminating machine and the length of the feed belt path. Printing substrate width W P The dimensions determined for plate making and printing.

[0029] A multi-layer composite lateral registration control method based on a unified benchmark includes the following steps:

[0030] 1) Define the material feeding direction of the base material strip as longitudinal and the width direction of the base material strip as transverse; select the center line 402 inside the wall panel group of the composite unit as the unified transverse reference line of the composite unit. The unified transverse reference line of the composite unit is used as the common center line of the transverse position of all base material strips and each adhesive layer, that is, the zero line of the calculated edge line or the marking line of each base material strip.

[0031] 2) Detect and adjust the lateral deviation of the centerline of each coating and laminating unit relative to the centerline of the laminating unit: the lateral deviation of the centerline 101 of the first coating unit wall panel relative to the unified lateral reference line 402 of the laminating unit |E B1 |≦0.2 mm, the lateral deviation between the center 201 of the second coating unit wall panel and the unified lateral baseline 402 of the laminating machine|E B2 |≦0.2 mm, the lateral deviation between the center 301 of the wall panel of the third coating unit and the unified lateral baseline 402 of the laminating machine|E B3 |≦0.2 mm; E B1 E B2 and E B3 All values ​​are vector values. A positive value is defined as the coating unit's wall panel centerline being located on the drive side of the laminating centerline; otherwise, a negative value is defined as the lateral deviation between the inner centerlines of the wall panels of any two units in the laminating machine (including coating and laminating units) |E. B1 -E B2 |≦0.5 mm,|E B1 -E B3 |≦0.5 mm,|E B2 -E B3 |≤0.5 mm;

[0032] 3) Control the lateral position and working width of each coating roller's working surface to ensure the lateral deviation of its coating area centerline relative to the centerline of the inner side of the wall panel group of its coating unit; the lateral deviation between the centerline 101 of the first coating roller's working area and the centerline 102 of the inner side of the first coating unit's wall panel group |E F1|≦0.2 mm, the lateral deviation between the center line 201 of the working area of ​​the second uniform roller and the inner center line 202 of the wall panel group of the second coating unit|E F2 |≦0.2 mm, the lateral deviation between the center line 301 of the working area of ​​the third uniform roller and the center line 302 of the inner side of the wall panel group of the third coating unit|E F3 |≤0.2 mm;

[0033] The width W of the printed image on the printing substrate used T If the width of the working surface of the first, second, and third leveling rollers is 600 mm, then the width of the working surface of the rollers is F1 = F2 = F3 = 600 mm, and the width of the coating is W. G =600 + 2 = 602 millimeters;

[0034] 4) The first unwinding substrate is a non-printed film, so the sensor of the first web correction probe assembly 15 is an ultrasonic sensor. The second unwinding substrate is a non-printed film, so the sensor of the second web correction probe assembly 16 is an ultrasonic sensor. The third unwinding substrate is a printed film, so the sensor of the third web correction probe assembly 17 is a photoelectric sensor or a CCD camera element. The fourth unwinding substrate is a non-printed film, so the sensor of the fourth web correction probe assembly 18 is an ultrasonic sensor.

[0035] The selected sensor has a detection accuracy of 0.01 mm and is mounted on a laterally movable slide driven by a motor via a ball screw. The motion accuracy of the slide is 0.01 mm. The zero position of the motor is adjusted so that the photoelectric sensor is aligned with the center line of the unit.

[0036] 5) Width of the first base material strip W1 = W T +K1=600+6=606 mm

[0037] The width of the second base material strip is W2=W T +K2=600+6=606 mm

[0038] The third base material strip is a printed film, with a width W3 = 612 mm.

[0039] The width of the fourth base material strip is W3 = W T +K3=600+4=604 mm

[0040] The lateral position coordinates of the detection center line of the first correction probe relative to the unified lateral baseline are Y1 = 0.5 * W1 = 303 mm.

[0041] The lateral position coordinates of the detection center line of the second correction probe relative to the unified lateral baseline are Y2 = 0.5 * W2 = 303 mm.

[0042] The lateral position coordinates of the detection center line of the third correction probe relative to the unified lateral baseline are Y3 = Y P =D =306 mm

[0043] The lateral position coordinates of the detection center line of the fourth correction probe relative to the unified lateral baseline are Y4=0.5*W4=302 mm;

[0044] 6) The calculated lateral position coordinates Y1, Y2, Y3, and Y4 of the detection centerline of each base material strip correction probe are transmitted as lateral movement increments of the slider to the position control motor of each correction probe. The motor drives the lead screw to move, and the lead screw moves each correction probe to the detection position. When the machine is started, each unwound base material strip performs correction with the detection centerline as the correction target position. This ensures that the centerline of each base material strip is corrected to a unified lateral reference line.
