Description
Technical field
The present invention relates to surperficial mint-mark stacking material of information code and the observational technique of information code, the improvement of the information reading performance when particularly on transparent material layer, having formed information code.
Background technology
At present, for production management or the circulation control of carrying out various goods, information code such as type slug font code or two-dimension code on the external packing of these goods or parts etc.
For example, to being provided to the commodity type information sign indicating number on the market, the terminal in each shop is connected with the principal computer of home office, the POS system (selling the time information management system) etc. of automatically carrying out sales volume management, stock control etc. is comparatively famous.In addition, two-dimension code is compared with bar code, contain much information, can write down commodity manufacturing location, make many information such as date, production number.Utilizing information code like this is very important to thoroughly carrying out production management and circulation control etc.
As the method that these information codes is written on metal covering or the thin slice etc., generally use laser marking (laser marking) method and printing ink mark (ink marking) method.Printing ink mark method is to have the printing ink of luminance difference to fix from the teeth outwards and write code with matrix material.Laser marking method (YAG laser, CO
2Laser etc.) also forming spill from the teeth outwards writes code by the surface irradiation laser to film or metal covering.
As the method that reads the information code that writes in a manner described, the general method that adopts the luminance difference (contrast) that reads code section and matrix material, the present automatic identifying method of developing the various codes that used the CCD lens.That is, the code that writes with printing ink mark method is by means of being read by the code of ink print and the luminance difference of matrix material.On the other hand, in the laser marking method, read code No. the 2719287th, Japan's patent (for example, with reference to) according to the reflection light quantity difference of the recess of concavo-convex code and protuberance (not being processed into the part of concave shape).
As mentioned above, for the circulation control of thoroughly carrying out product, stop Counterfeit Item etc., need be on product direct type information sign indicating number, the seal that perhaps will print information code directly sticks on the product.But printing ink mark method must obtain the luminance difference (white and black the easiest the reading of combination) of matrix material and printing ink, and available matrix material look and printing ink look are very restricted.Therefore, cause the intention of the product after information code is printed, pasted obviously to reduce.
In order to prevent the deterioration of above-mentioned intention, utilize above-mentioned laser marking method, on transparent membrane, print concavo-convex code, and this transparent membrane is sticked on the product, thus, information code is put down in writing, can not reduce the intention of this product again.
But, in the concavo-convex code that utilizes above-mentioned laser marking method to print, can not fully obtain the recess on the transparent membrane and the luminance difference (contrast) of par, usually when using the automatic cognizance code of CCD lens, can not read, or error is read in generation.
In order to address this problem, for example in No. the 2719287th, above-mentioned Japan patent, to have proposed the formation face irradiates light of angle in accordance with regulations, and received the reflected light that obtains from edge part, the method for discerning again concavo-convex code.But there is following defective in this method, that is: setting reading conditions, apparatus structure complexity and mechanical part price are high in detail to be subjected to restrictions such as the irradiating angle of light and the position of light accepting part.In addition, also there is the shortcoming of control laser marking condition in detail.

Embodiment
Below, with reference to description of drawings mint-mark of the present invention the preferred implementation of stacking material of information.At first, carry out the explanation of basic embodiment.Fig. 1 is the sectional view of the stacking material of present embodiment.This stacking material 10 is by light transmission high transparent material 12 and reflection loss layer 14 stacked formation.Information code is at the approximate hemispheric low-lying recess 16 (high reflecting part) of transparent material laminar surface formation and the distribution pattern of par 18 (low reflecting part) by mint-mark.The radius of this recess 16 is about 100 μ m usually, and the degree of depth is about about 50 μ m.In recess and the par as undressed part by processing such as laser, it is poor to produce reflection light quantity because of surface configuration is different.Have, the said low reflecting part of the present invention is meant the part that light transmission is high again.High reflecting part is meant surface reflectivity than low reflecting part height, but and do not mean that reflectivity is very promptly big, as long as the reflectivity of high reflecting part and low reflecting part is a little poor.That is to say, at this moment, because the surface of transparent material layer is provided with information code, thereby, the par 18 outside recess 16, light almost completely sees through.And for recess, because the diffuse reflection on surface only exceeds a little so reflectivity is compared with other flat.
Therefore, can read the reflection light quantity difference on recess 16 when utilizing rayed stacking material 10 and 18 surfaces, par and the information code of mint-mark.Here, used the thick PET film of 100 μ m, used pearl pigment as the material of reflection loss layer as the material of transparent material layer.By said structure, improved the precision that reads of concavo-convex code.In addition, as the material of transparent material layer except PET (polyethylene terephthalate), can also use PE (tygon), PP (polypropylene), PS (polystyrene), PMMA (polymethylmethacrylate) and glass etc., but be not limited to these materials.In addition, as information code, can use bar code or two-dimension code etc., but be not limited to these codes.
Below, compared with prior art, investigate and read the reason that precision improves.
At first, in order to compare, to illustrate and utilize viewed in transmitted light to be printed on the situation of the concavo-convex code on the transparent material layer.Fig. 2 be existing in transparent material layer 12 surface recordings have recording materials of the information code of recess 16 and par 18.From forming the face one side irradiates light of recess 16, utilize CCD camera 22 optical detection devices such as grade to observe the light that sees through transparent material layer 12 by light source 20.Because of transparent material layer 12 is formed by the high material of light transmission,, almost there is not the light of direct reflection so the major part of incident light sees through par 18.On the other hand, to the light of recess 16 incidents by recess 16 diffuse reflections.That is,, utilize the increase of the incident angle that produces because of its shape or reflection light quantity is increased because of the variation of the surface state that Laser Processing produced etc. at recess 16.As a result, the light amount ratio through recess 16 is relatively little through the light quantity of par 18.Therefore, in CCD camera 22, can observe the image that has produced contrast in recess and par.
When utilizing transmitted light to read information code as described above, use material transparent as mint-mark the material of information code can not go wrong.But, when not observing transmitted light when above this material being sticked on product etc., then utilize reflected light to read information code.Fig. 3 (a) be with mint-mark the transparent membrane of concavo-convex code (transparent material layer 12) carry out the key diagram of code when observing when sticking on above the product etc.Use identical symbol with the part that Fig. 2 is corresponding.Read according to carrying out like that usually.At first, from light source 20 irradiates lights, read information code by utilizing CCD camera 22 optical detection devices such as grade to detect its reflected light.The surface of the product of transparent material layer etc. has been pasted in substrate 24 expression.
As discussed above, because of transparent material layer 12 is formed by the high material of light transmission, so the major part of incident light sees through par 18, the light of direct reflection does not take place almost, to the light of recess 16 incidents by recess 16 diffuse reflections.Like this, should be able to utilize the reflection light quantity difference of par 18 and recess 16 to discern the concavo-convex code that is printed on the surface.But in the device shown in Fig. 3 (a), the light transmission transparent material layer 12 from substrate 24 reflection returns to the direction of CCD camera 22 (optical detection device), so the light quantity that is difficult to read par 18 and recess 16 is poor.Therefore, when substrate 24 is adopted as the bigger material of specular reflectances such as metal, can not use the material as mint-mark information such as transparent membrane.
In practice, use chromatics paper as substrate and change the color of substrate, carried out reading inspection.Its result is shown in following table 1.
(table 1)
Table 1 zero, Δ, * in zero the expression make mistakes hardly when reading, often make mistakes when Δ is represented to read, * expression almost can not read.Like this, when transparent membrane is directly sticked on substrate, even can not obtain the gratifying precision that reads at the bottom of reflecting minimum fast black base.
Therefore, in the present invention, below the transparent material layer 12 of having printed concavo-convex code, reflection loss layer 14 is set, reducing reflected light, thereby has overcome the problems referred to above from substrate 24.Fig. 3 (b) is its key diagram.The read method of message code of the present invention is identical with common read method.At first, utilize light source 20 to the stacking material irradiates light, the stacked material reflection of the light of irradiation utilizes optical detection device (CCD camera 22) to receive its reflected light.Carry out the image behind the light-receiving and become the image that has produced contrast at high reflecting part (recess 16) and low reflecting part (par 18).Utilize arithmetic units such as computing machine (not shown) that this view data is handled, from this view data, read information code.
Scattering takes place owing to the pearl pigments (mica of capping oxidation titanium) in this reflection loss layer 14 and is absorbed in the light that incides reflection loss layer 14, and the result has reduced the light quantity that sees through.In addition, the normal reflection trimmed book body from reflection loss layer 14 surface has also reduced.Thereby, even the stacking material 10 of present embodiment is sticked on the substrate 24 of the higher material of reflection of light rate, normal reflection takes place at the stacking material back side and the light quantity returned also less.Therefore, can be poor at recess 16 and par 18 generations by the light quantity that CCD camera 22 (optical detection device) reads.According to above reason, can think that reading of information code become easily.In fact, also obtained good result in the test described later reading.
Like this, if according to present embodiment,, read so can use common reading device to carry out high precision with CCD, lens etc. because of having produced higher contrast ratio at recess and par.In addition, the position of light source and reading device relation is also unfettered.
In addition, uncertain because of the directivity of incident light under general illumination light such as sunshine or fluorescent light, so illumination light incides the surface from a plurality of directions, be difficult to distinguish the diffusion light of recess and the normal reflection light of par.Therefore, under common lighting condition, the information code of transparent material laminar surface is not obvious, and the transparency of stacking material and the effect of security also are improved.
Be provided with the embodiment of adhesive linkage on Fig. 4 the has been illustrated in mint-mark stacking material of information.To using prosign with the part of Fig. 1 correspondence.In the stacking material of Fig. 4, (face of not mint-mark information code one side) is provided with adhesive linkage 36 overleaf.Utilize this adhesive coating 36 that stacking material is sticked on the article.Certainly, also adhesive linkage can be set especially, and use bonding agents etc. directly stick on stacking material on the article.
As the article of the stacking material of pasting present embodiment, for example, can enumerate computer software, music software, camera, cosmetics and case and bag etc.Like this, by with mint-mark the stacking material of information stick on the article, thereby can work effects such as preventing fake products, commodity information management.
Usually, the manufacturing management of product and circulation control for example stick on the product by the label etc. that uses bar code, two-dimension code etc. will write down the build date, manufacturing works, manufacturing approach, lot number, individual product number etc. of product and carry out.
Specifically, automatic method of carrying out stock control, the management of merchandise sales volume etc. as the POS system of narration in prior art one joint is arranged.
In addition, circulation control as product, following method is arranged: each commodity is pasted code, perhaps, when a plurality of product bale packings are cased, on to the chest of a plurality of product bale packings glue records the code of wherein each product information, make the delivery destination of these commodity corresponding, and be stored in the principal computer etc. of delivery side with product code.At this moment, as information code, also can write down information such as the delivery destination of these commodity or the number of packages of delivering.In these merchandise sales or when stocking up, read product code and be stored in the computing machine in shop.These data are sent in the principal computer of delivery side, contrast, thereby can check whether correctly delivery, carry out circulation control up hill and dale by data with the storage of delivery side.
In addition, in the management of product, in each procedure, process information and fox message are write as code, and carry out manufacturing management according to these information.In addition, in fair etc., data such as the Business Name of invited party and address are made two-dimension code, when admission by reading this code, thereby can make participant's inventory automatically.
Mint-mark of the present invention the stacking material of information because can very read the information code of mint-mark on this stacking material exactly, so can be applied to fully in the management of product carried out usually as described above and the circulation control etc.
Secondly, as the example of another embodiment, the stacking material that holofilm and retroreflecting layer are combined is described.Fig. 5 illustrates its sectional view.
The stacking material of Fig. 5 (a) is the material that transparent material layer 312, holograph layer 320 and reflection loss layer 314 is stacked together.The stacking material of Fig. 5 (b) constitutes transparent material layer 312, retroreflecting layer 322 and reflection loss layer 314 stacked back.In addition, the stacking material of Fig. 5 (c) constitutes transparent material layer 312, holograph layer 320, retroreflecting layer 322 and reflection loss layer 314 stacked back.
The sort of structure is all come recorded information by mint-mark in the combination of transparent material layer 312 lip-deep recesses (high reflecting part) and par (low reflecting part).Because with shown in Figure 1 identical, reflected light is decayed because of reflection loss layer 314, thereby reads the concavo-convex code of transparent material laminar surface easily.
Here, holograph layer 320 is preserved the interference fringe of the hologram image that is used for regenerating.As holograph layer 320, use the holographic thin slice from translucent to transparent.Retroreflecting layer 322 has the retroreflecting material that incident light is returned to the incident light direct of travel.It is that small hyaloplasmic sphere 324 proper alignment on resin bed 328 of 30～80 μ m forms that this retroreflecting material makes many particle diameters.Roughly be spherical hyaloplasmic sphere by small, produce to the reflected light of the roughly the same direction reflection of the incident direction of light.In addition, as reflection loss layer 314, use is by lepidiod mica and cover the pearl pigment (mica of capping oxidation titanium) that the titanium dioxide layer on this mica constitutes.In the present embodiment, reflection loss layer 314 effect in the reflection horizon in the retroreflecting material of having held concurrently.In addition, by using pearl pigment, when straight line light (light that finger direction is certain) incident, in retroreflecting light, can observe because of the caused interference color of interference of light as the reflection loss layer.That is, in the present embodiment, because of using pearl pigment as the reflection loss layer, thus by with the mutually stacked setting of retroreflecting layer, thereby can make it work to be used for making the interference material layer of retroreflecting light generation interference color simultaneously.The spy that the details of above-mentioned holograph floor and retroreflecting floor for example is documented in Japan's patent documentation opens in 2000-81831 communique and the Te Kai 2000-272300 communique.
In addition, also can be the same with the stacking material of Fig. 4, the adhesive linkage that is used for the article stickup is located at the back side (the not face of type information sign indicating number).
Above-mentioned stacking material is provided with the stacking material of reflection loss layer below the retroreflecting layer, but also the reflection loss layer can be set on the retroreflecting layer.Fig. 6 is its example.The stacking material of Fig. 6 (a) is in order with transparent material layer 112, holograph layer 120 and reflection loss layer 114 formation stacked together.Fig. 6 (b) carries out stacked stacking material with transparent material layer 112, reflection loss layer 114 and retroreflecting layer 122 in order.The stacking material of Fig. 6 (c) is in order transparent material layer 112, holograph layer 120, reflection loss layer 114 and retroreflecting layer 122 stacked back to be constituted.The same with Fig. 5, come recorded information by mint-mark in the combination of transparent material layer 112 lip-deep recesses (high reflecting part) and par (low reflecting part).Equally, holograph layer 120 is preserved the interference fringe of the hologram image that is used for regenerating.Retroreflecting layer 122 has the retroreflecting material that incident light is returned to the incident light direct of travel, and the retroreflecting material is that to make many particle diameters be that the small hyaloplasmic sphere 124 of 30～80 μ m proper alignment on resin bed 128 forms.In addition, be layered in retroreflecting layer 122 following interference material layer 134 and constitute, have the effect that makes retroreflecting light generation interference color because of interference of light by lepidiod mica and the titanium dioxide layer that covers on this mica.
The stacking material of present embodiment is by the combination of holograph layer and retroreflecting layer, can improve to prevent the effect of palming off.And then, utilize holographic light diffusion (dazzling sensation) to make information code with the naked eye seem not obvious, intention is higher.In addition, because of information code is concavo-convexly carried out record as what form on the surface of transparent material, so can not influence hologram image.
In addition, above-mentioned stacking material can be brought into play better effect by on the main body or Product labelling that stick on the easy commodity of palming off such as computer software, music software, senior brand product (camera, cosmetics, dress material and bag etc.).Like this, the article of having pasted stacking material of the present invention improve by the combination that utilizes holograph layer and retroreflecting layer and prevent the effect of palming off, thereby discern counterfeit easily.Simultaneously, also can utilize the information code of mint-mark on stacking material to carry out commodity information management.
Secondly, the embodiment that utilizes printing ink mark method to carry out the information code printing on transparent material layer is described.Fig. 7 illustrates the stacking material that uses printing ink mark method type information sign indicating number.Fig. 7 (a) is the stacking material that transparent material layer 212, holograph layer 220 and reflection loss layer (pearl pigment layer) 214 is stacked together.Fig. 7 (b) is the stacking material that transparent material layer 212, reflection loss layer 214 and retroreflecting layer 222 is stacked together.Fig. 7 (c) is the stacking material that transparent material layer 212, holograph layer 220, reflection loss layer 214 and retroreflecting layer 222 is stacked together.In addition, being located at the following of retroreflecting layer 222 is to interfere material layer 234, has the effect that produces interference color.Have again, also can adopt the structure of below the retroreflecting layer, establishing the reflection loss layer as shown in Figure 5.The stacking material of Fig. 7 (a) and (b), (c) and Fig. 6's is different, and information code 240 utilizes ink printing on the surface of transparent material layer.In the present embodiment, utilize the information code 240 of ink print to become high reflecting part, all the other unprinted parts become low reflecting part.
In the embodiment of Fig. 7, because of information code 240 is used ink printing, so visually damage the hologram image of holograph layer sometimes.Therefore, for example transparent and make the material of the light reflection of infrared region in the visible region if the printing ink of printing information sign indicating number adopts, and use infrared ray to carry out reading of information code, then can prevent from visually to damage hologram image.In addition, can make color of ink not obvious and do not damage the intention of product.But in fact, the kind of printing ink etc. is subjected to restriction to a certain degree.In addition, rub resistance or weather proofing are compared low slightly with concavo-convex code.
But, if image pattern 1, Fig. 3, Fig. 5, as shown in Figure 6, utilize the laser marking method on transparent material layer mint-mark as the information code of concavo-convex code, then can not damaged hologram image mint-mark the stacking material of information code.In addition, rub resistance or weather proofing are also better.
Here, the two-dimension code that once uses in the present embodiment of simple declaration.Two-dimension code records the information in the code that forms on the two-dimensional surface after being the transformation of data into binary data again.For example, be divided into white and black two kinds of colors, perhaps utilize the concavo-convex figure that writes.Fig. 8 is the figure after its part is amplified.That is, shown in Fig. 8 (a), utilize the figure of unit 410 to come recorded information.This unit 410 is equivalent to recess.Usually, the most image pattern 8 in unit (a) is represented with square like that.But the shape of unit is not limited to square, as long as can read dot pattern.For example, when utilizing laser to write recess, the methods such as capable mark shown in the dot matrix mark shown in Fig. 8 (b) or Fig. 8 (c) are arranged.The dot matrix mark is when describing a unit, and not mobile laser carries out mark.Therefore, unit 410 uses the point of sub-circular to describe one by one.The size of recess can be regulated by setting print conditions.
Such capable mark shown in the image pattern 8 (c) utilizes many lines to describe a unit.Here, illustrate and utilize 2 lines to describe the example of a unit 410.In addition, generally go mark to read precision higher.
The laser marking method of two-dimension code more than has been described, but in the present invention no matter what method can obtain the good result that reads.In addition, be not limited to two-dimension code as the information code of using.
Stacking material of the present invention has been carried out the test of reading of following concavo-convex code like that.
Transparent material layer uses the PET film, utilizes the laser marking method to form recess (high reflecting part) on its surface, and prints concavo-convex code.Concavo-convex code uses two-dimension code, and has carried out the test of reading of code.
At first, the manufacturing of stacking material is carried out as following.As the material of transparent material layer, used the thick PET film of 100 μ m.Material as the reflection loss layer, used the material of following formation: the pearl pigment of 1g and the celluloid lacquer No.4341 of 15g (Musashi coating (share)) are mixed, after stirring, disperse with diverting device, utilize and scrape ink sheet (doctor blade) and on the thick PET film of 100 μ m, its dry back is formed its coating (De ロ-ダ ウ Application) with the surplus of 101 μ m.Writing of code utilizes the laser marking method to carry out.Utilize CO
2Laser mark printing device (electrode is made made in LSS-SO50VAH (share) pick) is to the surface irradiation laser of above-mentioned transparent material, forms radius and is about 100 μ m, is about the recess of 50 μ m deeply, and print concavo-convex code.Concavo-convex code uses the two-dimension code of data matrix mode (writing 30 of English digitals in the square of 4.0mm).
When forming recess, for the radius that makes recess is about 100 μ m, the degree of depth is about 50 μ m, above-mentioned CO with above-mentioned dot matrix mark

Following table 2 is respectively at stacking material of the present invention (embodiment 1,2,3) and the test findings that reads precision when having only transparent membrane (comparative example 1).In addition, the highest white paper of reflectivity is used in substrate.Table 2 zero, Δ, * in zero the expression make mistakes hardly when reading, often make mistakes when Δ is represented to read, * expression almost can not read.
(table 2)
As shown in Table 2, embodiment 2,3 produces hardly and reads error.Though often produce under the situation of embodiment 1 and read error, can read.Comparative example 1 almost can not read.Hence one can see that, and the stacking material of the application of the invention can read information code with enough precision.
In addition, in embodiment 1, frequent generation is read reasons of error and is considered to, because the brightness height of appearance color and reflection of incident light light quantity are big, so the scattering of light effect that the reflection loss layer causes is less.But this test is the test of reading under quite strict condition, under physical condition, even the stacking material of embodiment 1 also may be brought into play sufficient performance.In fact, in the test that has changed following substrate color, can obtain enough precision that reads.Table 3 is the test findings when having changed the substrate color.Table 3 zero, Δ, * identical with table 2, zero the expression make mistakes hardly when reading, often make mistakes when Δ is represented to read, * expression almost can not read.
