The specific embodiment
For making object of the present invention, technical scheme and effect clearer, clear and definite, referring to accompanying drawing examples, the present invention is described in more detail.
Refer to Fig. 2, it is that sheet-fed of the present invention is gold stamping, the schematic diagram of die-cutting device electronic position-fixing device.As shown in the figure, described positioner comprises: framing module 100, position determination system 200 and adjusting device 300, it is simple for describing that described framing module 100 is printed on sheet-fed printed matter 30(, below also referred to as sheet-fed) upper, described position determination system 200 is electrically connected to adjusting device 300.
Specifically, described framing module 100 is when sheet-fed 30 printing, be printed onto on sheet-fed 30. for sheet-fed 30 post-press finishings, when (comprising secondary printing), determine the position of printed patterns, in general, the color of described framing module 100 should be aberration contrast large (being convenient to identification), cover position requires high color, such as: after sheet-fed printing, on paper, there is shades of colour (A, B, Deng) pattern, when following process (such as: cross cutting), required precision to the pattern of color A is higher, the color of framing module 100 should be adopted to color A, can also further its position be arranged on to the blank position place of printed matter, during for follow-up location, the accuracy of the location of the image of assurance color A.That the number of described framing module 100 can be for a plurality of: number is more, and it is more accurate to locate, but successive image intractability is larger with being to be understood that.In general, two framing modules 100 just can realize comparatively accurately and having located.
Please continue to refer to Fig. 3, in the present embodiment, described framing module 100 be shaped as right-angled trapezium (color require a highest color for cover position), its height is that 1 centimetre of upper base is 0.2 centimetre, going to the bottom is 1 centimetre.Can certainly adopt triangle, or other shapes.
Described position determination system 200 is for reading images locating module 100, compares, thereby calculate the site error of sheet-fed printed matter with the image of pre-stored reference format.
Further, please continue to refer to Fig. 2, described position determination system 200 comprises: image collecting device 210, include the processor 220 of memory module, described image collecting device 210 is for gathering framing module, and the framing module collecting is sent in processor; Memory module in described processor 220 is for the view data of storage standards form; Described processor 220, for the view data of framing module and reference format is compared, calculates deviation between the two, thereby releases the site error of sheet-fed printed matter.
See also Fig. 3 and Fig. 2, in position fixing process, image collecting device 210(in the present embodiment, described image collecting device 210 is photoelectric scanning head) scan framing module 100, the view data of itself and reference format is compared, thereby determines deviation between the two: its detailed process is as follows:
Sheet-fed printed matter is along direction from the bottom up move (establishing this direction is Y-direction), image collecting device 210 first scans framing module 100 hypotenuses and goes to the bottom, calculate its hypotenuse center and the distance H 1 at the center of going to the bottom, then compare with the view data of reference format, whether the length of judging described H1 identical with reference format, release sheet-fed printed matter and whether occur deviation in Y-direction: be as longer in H1 length, sheet-fed printed matter position is described on the upper side, H1 length is shorter, shows the position of sheet-fed printed matter on the lower side; In like manner, whether image collecting device 210 continues scan image locating module 100, gathers the distance H 2 at its trapezoidal Yu Gao center, hypotenuse center, identical with reference format according to H2, releases sheet-fed printed matter and on directions X, whether occurs deviation.Thereby be convenient to follow-up adjusting.About Digital Image Processing and comparison, in prior art, there have been a lot of methods, just repeated no more here.
The site error of described adjusting device 300 for calculating according to position determination system, the position of adjusting sheet-fed printed matter.In the present embodiment, described adjusting device 300 comprises: location tooth row 310, is arranged on directions X adjusting device 320 and Y-direction adjusting device 330 on the tooth row of location.Described location tooth row is for first fixing sheet-fed 30, then by directions X adjusting device 320 and 330 pairs of sheet-fed printed matters 30 of Y-direction adjusting device, regulate, thereby realized the location of sheet-fed printed matter, and behind location, passed to follow-up splicing tooth row, then carry out subsequent treatment.Described directions X adjusting device 320 and Y-direction adjusting device 330 are respectively used at directions X and Y-direction, sheet-fed be regulated.The site error that its degree of regulation should calculate according to position determination system regulates.So, no matter whether sheet-fed 30 printed matters are cut tiltedly, are printed the phenomenons such as askew, can accurately locate it: because carry out according to framing module 100 its location.Further, described directions X adjusting device 320 and Y-direction adjusting device 330 are driven by motor.
As shown in Figure 3, the present invention also provides that a kind of above-mentioned sheet-fed is gold stamping, the localization method of die-cutting device electronic position-fixing device, and it comprises the following steps:
S1, the sheet-fed that is printed on framing module are sent to station place, location;
S2, position determination system reading images locating module, compare with the view data of pre-stored reference format, thereby calculate the site error of sheet-fed;
S3, adjusting device are fixed sheet-fed printed matter;
The site error that S4, adjusting device calculate according to position determination system, regulates the position of sheet-fed, and the sheet-fed of adjusted position postpone is passed to splicing parts.
Further, described step S2 also comprises:
S21, image collecting device gather framing module, and the framing module collecting are sent in processor;
S22, processor are compared the view data of the reference format in framing module and memory module, calculate deviation between the two, thereby release the site error of sheet-fed.
Above-mentioned concrete localization method have been described in detail in the above.Be, the view data of the reference format in memory module is the view data that includes framing module with should be noted that, and in described image, the position of framing module is normal place.So, as long as can make the framing module in the image of framing module and reference format be mapped, no matter sheet-fed cut tiltedly still print askew, can guarantee following process pattern accurately.
