Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of punching of the embossing for colored printing system real-time correction of error device, comprise interconnective color mark sensor 3 and correction processing unit 10, color mark sensor 3 is arranged on the feed side of printing material 4, printing material 4 is wrapped on final drive shaft 2, the arranged outside of final drive shaft 2 has the velocity location encoder 1 rotated together with final drive shaft 2, correction processing unit 10 includes electric cam tracking cell 101, location acquiring unit 102, error acquiring unit 103, error correction unit 104, velocity location encoder 1 and electric cam tracking cell 101 are electrically connected, color mark sensor 3 is electrically connected with location acquiring unit 102, electric cam tracking cell 101 is connected with location acquiring unit 102, location acquiring unit 102 is connected with error acquiring unit 103, error acquiring unit 103 is connected with error correction unit 104.The interlude of printing material 4 is provided with Embosser 11 and perforating device 12, and Embosser 11 includes dandy roll 6 and lower corrugated roll 7, is provided with embossing point 13 between upper dandy roll 6 and lower corrugated roll 7.Perforating device 12 includes perforated roll 8 and lower perforated roll 9, is provided with drilling point 14 between upper perforated roll 8 and lower perforated roll 9, is provided with and locates rubber roll 5 between final drive shaft 2 and Embosser 11.
The implementation step that the utility model embodiment is used for the embossing perforating device real-time correction of error of colored printing system is as follows:
(1) the mark zero position of embossing point 13 and drilling point 14 is obtained and is obtained by the passive back to zero of system by correction processing unit 10.
(2) according to the perimeter L of upper dandy roll 6, color mark sensor 3 cursor calculates embossing detection target location Y to the distance M of embossing point 13.
(3) calculate the open interval obtaining Embosser 11 and perforating device 12 feed side color mark sensor 3, in open interval, ensure that only having embossing to be masked as color mark sensor 3 detects.
(4) startup optimization, when the color mark sensor 3 of Embosser 11 and perforating device 12 feed side detects the embossing mark on printing material 4, location acquiring unit 102 obtains the positional value X of Embosser 11 and perforating device 12.
(5) error acquiring unit 103 is according to positional value X and target location Y.Obtain embossing and correct error E RROR=Y-X, and complete embossing punching error correction by error correction unit 103 in real time.
In the present embodiment, the expression formula of angle on target Y is Y=(L-M+F) * 360/L, and wherein L is dandy roll girth, and M is the length of color mark sensor 3 hot spot to the printing material 4 of embossing point 13, and F is system compensation value.Wherein system balance spacing F is for solving plate-making or changes in material generation system balance, and F is 0 millimeter under normal circumstances.
The detailed step calculating the open interval obtaining feed side color mark sensor 3 in the present embodiment step (3) is: the interval angle Q of detection window calculating color mark sensor 3 according to Q=(R/L) × 360, according to W1=Y-Q/2 calculate color mark sensor 3 angle of release degree W1, according to W2=Y+Q/2 calculate color mark sensor 3 close angle W2, according to angle of release degree W1 and the open interval W closing angle W2 acquisition color mark sensor 3 of color mark sensor 3, wherein R is that color mark sensor 3 detection window is interval, and Y is embossing target location.In the present embodiment, angle of release degree W1 according to color mark sensor 3 specifically refers to the open interval W closing angle W2 acquisition color mark sensor 3: when the value of the angle of release degree W1 of color mark sensor 3 is timing with the value of closing angle W2, effective open interval of color mark sensor 3 is W1<W<W2, otherwise color mark sensor 3 valid interval is W1<W<360 and 0<W<W2.
The embossing processes of the present embodiment is as follows: dandy roll perimeter L is 500 millimeters.
Color mark sensor 3 cursor is to embossing dot spacing M=350 millimeter.
System balance spacing F is 0 millimeter.
R is that detection window is interval, default value 20 millimeters.
Embossing desired value Y=(L-M+F) * 360/L=(500-350+0) * 360/500=108 degree.
Interval angle Q=(R/L) × 360=(the 20/500) × 360=14.4 degree of color mark sensor 3 detection window.
Color mark sensor 3 angle of release degree W1=Y1-Q/2=108-14.4/2=100.8 degree.
Color mark sensor 3 closes angle W2=Y2+Q/2=108+14.4/2=115.2 degree.
When color mark sensor 3 detects that embossing mark correspondence position X=112 spends, then forme correction error ERROR=Y-X=108-112=4 degree.Final adjustment embossing position and speed superposition 4 degree, to the performance element of error correction, completes embossing real-time correction of error.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
