Abstract

A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including a substrate, a thermochromic layer and a light absorbent layer located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The media optimally includes obscuration materials to reduce the visibility of the light absorbent layer to the naked eye. The light absorbent layer is preferably a low cost absorber such as carbon black. An alternate form of the invention is a two layer laminate media including a substrate and a thermochromic layer. The invention is usable in conjunction with labeling produce items. The invention includes a method and apparatus for using media in conjunction with labeling produce items.

技术领域 FIELD

[0003] 本发明总体涉及激光(或者其他高强度光)可标记介质,用作例如贴标签机和/ 或用于封装或者其他打印应用包括销售点的薄膜打印、传真机和层压卡(例如身份证)打印机的标签。 [0003] The present invention generally relates to a laser (or other high intensity light) markable media, as e.g. labeling machine and / or encapsulated or other print film printing applications, including fax machines and point of sale of laminated cards (such as identity certificate) label printer.

背景技术 Background technique

[0004] 贴标签和封装市场不断需求更快速、更加成本有效的标记系统,能够为具有较长寿命的非平表面印标记,并且能“飞速地”印上标签或者封装膜。 [0004] Labeling and packaging market continues to demand faster and more cost-effective marking system that is non-flat surface having indicia printed a longer lifetime, and can be "fast to" printed label or package film.

[0005] 如现有技术所公知的,高容量标签介质的直射激光阵列标记具有许多优势:无油墨或者墨带、无接触(使得头部寿命更长)并且允许非平介质或者打印在非平基板上;参见已出版的PCT专利申请WO 05/049332-2005年2月6日出版。 [0005] The prior art is well known, high-capacity direct laser array marking label medium has many advantages: no ink or ink ribbon, non-contact (such that the head and longer life) and allows printing on non-planar or non-planar media a substrate; see published PCT patent application WO 05 / 049332- published February 6, 2005.

[0006] 现有技术中同样公知的是,二极管激光阵列能够提供低成本、紧凑、告诉、高可靠度的方案,以生产待涂敷的标签标记辊。 [0006] The prior art is also well known that laser diode arrays provide low cost, compact, tell, high reliability embodiment, the label roll to produce a mark to be coated.

[0007] 现有技术的直射激光标记系统的主要缺点在于它们需要二极管激光器的NIR(近红外)波长敏感的介质。 [0007] The main disadvantage of the direct laser marking system of the prior art is that they require the laser diode to the NIR (near infrared) wavelength sensitive medium. 传统方法需要具有窄吸收带的NIR(近红外)吸收器,因为在可见波长范围内的任何剩余吸收将导致介质的可见着色。 The conventional methods require a narrow absorption band having a NIR (near infrared) absorber, because any residual absorption in the visible wavelength range will result in visible coloring medium. 在大多数情况下,白色或无色介质是优选的,因此着色是不需要的。 In most cases, the preferred medium is a white or colorless, and thus the coloring is not required. 另外,窄带NIR吸收器成本较高,明显地增加了介质的成本, 当在类似于封装/产品标记的情况下使用时,成本需要非常低。 Further, the high cost of narrow-band NIR absorbers, significantly increases the cost of the medium, when used in the case of similar package / product marking, require very low cost.

[0035] 三层介质的“背侧丨”标记 [0035] "backside | 'or three media mark

[0036] 图IA和IB示出新颖的多层层叠标签60的“背部标记”的整体概念。 [0036] FIGS. IA and IB illustrates a novel multilayered label 60 "back flag" of the overall concept. 标签60包括具有背表面61a和前表面61b的半透明塑料基板61。 Label 60 includes a front surface 61a and back surface 61b of the translucent plastic substrate 61. 吸光材料层62 (优选地炭黑)通过被应用为由基板61的前表面61b承载的薄膜或者通过嵌入基板61中临近前表面61b的位置处而由基板60的前表面61b承载。 Light absorbing material layer 62 (preferably carbon black), a thin film made of the front surface 61b of the substrate 61 by being carried by the embedded application or at a position near the front face 61b of the substrate 61 being carried by the front surface 61b of the substrate 60. 热变色层63优选地由吸光层62的前表面62b承载并且与之热接触。 The thermochromic layer 63 is preferably carried by the front surface 62b light-absorbing layer 62 and in thermal contact therewith. 热变色层63具有背表面63a和前表面63b。 The thermochromic layer 63 having a front surface 63a and back surface 63b. 前表面6¾形成标签60的前部可视表面。 6¾ front surface portion forming the front surface of the label 60 is visible. 激光编码装置(或者高强度光源)40的输出41由吸光层62局部地吸收并且转换为热量。 Output of the laser coding apparatus (or a high intensity light source) 40 is absorbed by the light absorption layer 41 is locally 62 and converted into heat. 光源40可以是一个或多个CO2激光、一个或多个二极管激光、可编址激光阵列或者一个或多个LED。 The light source 40 may be one or more CO2 laser, or a plurality of laser diodes, laser addressable array or one or more LED. 如现有技术公知的,通过操纵光源或者通过对激光阵列编程而使光源40的输出41形成所需的图像。 , By manipulating the output of the light source 41 or by forming a desired image as known in the art of programming the array laser light source 40. 在层62中吸收的热量被立刻传导入热变色层63并且使得层63的选定部分改变颜色或者改变视觉外观从而形成所需的图像。 The heat absorbed in the layer 62 is immediately transmitted into the thermochromic layer 63 and selected portions of layer 63 such that the change in color or visual appearance change to form the desired image. 词组“改变视觉外观”意味着改变颜色、明暗度或者外观的其他可视觉检测到的改变。 The phrase "changing the visual appearance" means changing the color, shading, or other visual appearance of the detected changes.

[0037] 图IA和IB示出本发明的“背部标记”实施例,其中的激光(或者其他光源)辐射41穿过介质60的背部或后部(未示出)表面61a。 [0037] FIGS. IA and IB illustrate the present invention "back label" embodiment, wherein a laser (or other light) radiation through a back or rear 41 of the medium 60 (not shown) surface 61a. 介质60包括三层:前层63、后层61和低成本的中间吸光层62。 Medium 60 includes three layers: a front layer 63, intermediate layer 61 and the low cost of the light absorption layer 62. 图IB示出观察最终标记68的观察者的眼睛65。 FIG IB shows the final observation 68 of the observer's eye mark 65. 光由低成本的吸光层62吸收,该吸光层吸收宽频谱的光,包括NIR,该层也吸收可见光。 Light 62 is absorbed by the light absorbing layer is a low cost, the light absorbing layer absorbs a broad spectrum, including the NIR, the layer can absorb visible light. 这种材料更方便地可采用墨水,比窄带NIR吸收器更便宜(大约便宜80%)-—个实例是炭黑。 Such materials may be employed more easily the ink, and cheaper than a narrowband NIR absorber (approximately 80% cheaper) - instances is carbon black. 而且,该层可由更宽波长范围包括可见光的光源激活。 Further, this layer may be a wider range of wavelengths including visible light activation. 临近吸光层62的是执行两项功能的热变色层63 :该层响应于当所施加的光辐射由吸光层62吸收并且传入热变色层63时产生的热量改变颜色或者改变视觉外观,该层优选地使吸光层62模糊使得吸光层62的可见度减小或者当如图IB所示从前表面观看介质时肉眼无法看到。 Adjacent light absorbing layer 62 is thermochromic layer performs two functions 63: This layer in response to when the light applied radiation is absorbed by the light absorption layer 62 and pass the heat generated when the thermochromic layer 63 change color or change the visual appearance of the layer preferably the light absorbing layer 62 such that the blur of the light absorbing layer 62 visibility is reduced or when viewed from the front surface of the medium shown in FIG. IB can not see them. 颜色(或者可视外观)改变功能可通过任何的热变色化学实现,诸如使用在标准直射热介质中的(例如包括Ieuko染色和颜色催化剂的涂层)。 Color (or visual appearance) may be achieved by changing the function of the thermochromic any chemical, such as a direct heating medium used in the standard (e.g. a catalyst including Ieuko dyeing and color coating). 其他实例是包括颜色催化剂、显色剂和感光剂的涂层。 Other examples are catalysts comprising a coating color, color developing agent and sensitizer. 因此,这已经是低成本的大市场产品。 So, this is the largest market for low-cost products. 模糊功能可通过将发散材料加入至热变色前层63而得以增强。 Fuzzy diverging function by adding material to the front of the thermochromic layer 63 is enhanced. 例如, 适当尺寸的T^2颗粒对于在薄层中实现模糊来说是非常有效的。 For example, appropriately sized particles for T ^ 2 implemented in thin layers is very effective blur. 颜色改变前层63中的散光材料的其他益处是一次通过吸光层的未被吸收的光通过前层中的散光材料而被反射或者向后分散(如图9A-9B和10A-10F所示以及如下所述),由此再次穿过吸光层62以再次被吸收。 Other benefits astigmatism color change material before first layer 63 is dispersed by being reflected or back (as shown in Figure 9A-9B and 10A-10F in the front layer by light scattering materials light absorption layer and unabsorbed as described below), thereby passing through the light absorption layer 62 again reabsorbed.

[0038] 这种设计的一个限制是用作后层61的任何基板必须是半透明的,以允许光到达吸光层62。 [0038] One limitation of this design is that after the substrate 61 is used as any layer must be translucent to allow light to reach the light absorbing layer 62. 术语“半透明的”,如这里所使用的以及在权利要求中所使用的,意味着透明地或者足以传送输出光束以形成所需的图像。 The term "translucent", and as used herein, means a transparent or sufficient transmission output as used in the claims, a light beam to form the desired image. 这可以是聚合物,例如但是并不局限于,聚乙烯、 聚丙烯和聚酯。 This may be a polymer, such as, but not limited to, polyethylene, polypropylene and polyester.

[0039] 为了实现最佳的感光性,应该最大化相应于给定激光能量的变色层63的峰值温度。 [0039] In order to achieve optimum sensitivity, the temperature should be maximized to a peak corresponding to a given laser energy electrochromic layer 63. 这可通过下述步骤实现: This may be achieved by the following steps:

[0044] 需要指出的是,图IA和IB所示的介质60的“背侧”激光标记可用在各种打印、贴标签和封装应用中。 [0044] It should be noted that the media 60 and shown in FIG. IA IB "back side" of the laser marking can be used in various printing, labeling and packaging applications.

[0045] 三层介质的“前侧”标记 [0045] "front side" marker three media

[0046] 图2A和2B示出根据本发明的穿过三层层叠介质160的前侧的直射激光标记。 [0046] Figures 2A and 2B show direct laser marking three-layer laminate of the medium 160 through the front side in accordance with the present invention. 该实施例可用在诸如贴标签、封装或者其他打印应用的应用中。 This embodiment may be used in applications such as labeling, packaging or other printing applications. 如图2A和2B所述,激光束(或者其他高强度光束诸如激光二极管阵列)341从光源140射出并且应用到具有前表面163b、后表面161a以及具有三个分离层即前层163、后层161和低成本中间或中部吸热层162的介质160。 2A and FIG. 2B, the laser beam (or other high intensity light beam such as a laser diode array) 341 emitted from the light source 140 and having a front surface 163b is applied to, the rear surface 161a and has three front layer 163 off layer after layer 161 and low-cost intermediate or middle layer 162 absorbing medium 160. 此时,使用前部标记对前层163进行标记,但是保留宽带吸收剂162(例如炭黑)的低成本优势。 At this time, the front portion of the front layer mark numerals 163, 162 but retain broadband absorber (e.g., carbon black) cost advantage. 此时,为了避免吸光层162被观看前表面16¾上的最终标记168的观察者165(如图2B所示)看到,覆盖的热变色前层163在可视的范围内形成为不透明的, 但是仍然允许处于激活波长一般为700nm-1600nm的光穿过。 In this case, in order to avoid light-absorbing layer 162 is ultimately viewed marked on the front surface 168 of 16¾ observer 165 (FIG. 2B) to see, prior to the thermochromic layer is opaque cover 163 is formed in the visible range, but still allow active light passing through a wavelength typically of 700nm-1600nm. 这可通过结合折射率与热变色前层163不匹配且在激活波长中较小但在可见波长范围中较大的绝缘材料的颗粒来实现。 This mismatch in the active and the smaller wavelength in the visible wavelength range, but larger particles of the insulating material is achieved by combining the refractive index of the front layer 163 thermochromic.

[0047] 为了最大化这种情况下的感光度,需要吸收层162中的高吸收系数以最大化所产生的热量与热变色层163的邻近度。 [0047] In order to maximize the sensitivity in this case, the proximity of the heat and the thermochromic layer 163 in the high absorption coefficient 162 generated needed to maximize the absorption layer. 最小化热变色层163和任何覆盖层(未示出)的厚度也可通过最小化散热来最大化感光度。 Minimize the thickness of the thermochromic layer 163 and any covering layers (not shown) may also be maximized by minimizing heat sensitivity.

[0048] 图1A、1B、2A和2B所示的标记系统是“非直射”光标记系统或者技术,其输出光首先由吸光层(62、162)吸收、通过吸光层(62、162)转化为热量然后热传导至热变色层(63、163)以产生所需的标记。 [0048] FIGS. 1A, 1B, 2A and marking system shown in FIG. 2B is a "non-direct" optical marking system or technology, the output light is first absorbed by the light absorbing layer (62, 162), converted by light absorption layer (62, 162) then heat is conducted to heat the thermochromic layer (63, 163) to produce the desired mark.

[0049] 图3A和;3B示出包括可选模糊装置80的多层介质60,如图IA和IB所示。 [0049] and FIGS. 3A; 3B shows the fuzzy dielectric multilayer 60 including optional device 80, shown in FIGS. IA and IB. 如图3A所示,基板61具有如上所述的背表面61a。 3A, a substrate 61 having a back surface 61a as described above. 吸光层62示出在图3A中,承载在基板61的表面上。 The light absorbing layer 62 is shown in Figure 3A, carried on the surface of the substrate 61. 如图3A所示,模糊装置180是位于吸光层62和热变色层63之间的材料层181。 3A, device 180 is a fuzzy layer 181 located between the absorbing material 62 and the light absorbing layer the thermochromic layer 63. 模糊装置80的目的是减小吸光层62暴露至肉眼的可见度。 Fuzzy object apparatus 80 is to reduce the light absorption layer 62 is exposed to the naked eye visibility. 层181可由下述材料中选出: TiO2颗粒、碳酸钙颗粒、蜡粉和其中形成气泡的聚合物矩阵。 Layer 181 may be selected from the following materials: TiO2 particles, calcium carbonate particles, wax and a polymer matrix in which gas bubbles are formed. 模糊层181是至少一种半透明材料与上述材料组其中之一的微观混合物,其中的半透明材料的折射率不同于所述组中的材料。 Fuzzy layer 181 is a mixture of at least one micro-translucent material and wherein one of the group of materials, wherein a refractive index of a translucent material different from the material in the group. 模糊层181应该优选较薄并且具有高导热率以实现吸光层62与热变色层63之间的最佳热接触。 Fuzzy layer 181 should be thin and preferably have a high thermal conductivity to achieve an optimum thermal contact between the light absorption layer 62 and the thermochromic layer 63.

[0050] 可选择地,模糊装置80可包括可变的模糊层181,其中的热变色作用通过改变模糊程度来实现(即,不使用白色燃料)。 [0050] Alternatively, the device 80 may comprise fuzzy fuzzy variable layer 181, wherein the thermochromic effect is achieved (i.e., the fuel is not white) by changing the degree of blurring. 例如,层181在没有受热时可以是半透明的,从吸光层62传过来的热使其变为不透明的,例如,通过聚合物基体中的气泡的形成,由此使吸收层模糊化。 For example, in the absence of heating layer 181 may be translucent, heat from the light absorption layer 62 pass over it becomes opaque, for example, by the formation of bubbles in the polymer matrix, thereby obscuring the absorbing layer. 可选择地,模糊层181在没有受热时可具有不透明的状态,从吸光层62传导过来的热量使得模糊层181半透明,例如通过将蜡粉熔化在气体/蜡混合物中,由此允许黑色的吸收层62在暴露区域中是可以被看见的。 Alternatively, in the absence of blur layer 181 may have an opaque state is heated, the heat from the light absorption layer 62 over conductive layer 181 such that the fuzzy translucent, for example by the wax melted in a gas / wax mixture, thereby allowing the black absorbent layer 62 in the exposed areas can be seen.

[0051 ] 图:3B示出本发明的备选实施例,其中,模糊装置185并非形成分离的层,而是嵌入热变色层163中。 [0051] FIG: 3B shows an alternative embodiment of the present invention, wherein the fuzzy forming apparatus 185 is not a separate layer, but the thermochromic layer 163 is embedded. 该备选模糊装置185执行基本上与图3A所示的模糊装置180相同的功能。 This alternative device 185 perform substantially the same fuzzy blur function apparatus 180 shown in FIG. 3A. 模糊装置185优选地尽可能接近吸光层62定位,但是在任何情况下位于吸光层62与热变色层63的前部可见表面6¾之间。 Fuzzy device 185 is preferably close to the light absorbing layer 62 is positioned as far as possible, but in any case is located in the front portion of the light absorbing layer 62 and the thermochromic layer 63 between the visible surface 6¾.

[0053] 图4是图IA和IB所示的介质60的示意图,其中,吸光层62m嵌入基板层61。 [0053] FIG. 4 is a schematic diagram of the medium 60 and shown in FIG.

[0054] 作为将吸光层嵌入基板61的备选方案,如图4所示,吸光层62或162 (图ΙΑ、1B、 2A和2B)可通过苯胺印刷添加至所述基板,然后通过苯胺印刷将热变色层63或163添加至所述吸光层62或162以得到如图1A、1B、2A和2B所示的三层独立的层。 [0054] As an alternative light-absorbing layer is embedded in the substrate 61, shown in Figure 4, light absorbing layer 62 or 162 (FIG.

[0057] 使用多层叠层对产品贴标签 [0057] The multilayer laminate of the product labeling

[0058] 现有技术一般需要分离的贴标签机和标签设计用于每个寻价(price lookup)或者“PLU”数字。 [0058] The prior art generally require a separate labeling machines and label designs for each RFQ (price lookup) or "PLU" numbers. 零售商需要PLU数以促进付款时的快速处理和精确的计价。 Retailers need to deal with the number of PLU to promote rapid and accurate pricing at time of payment. 例如,为了将表示气“小”或“中”或“大”尺寸符号的标签添加至苹果,现有技术一般需三种分离的贴标签机、三种分离的标签设计和三种标签存货。 For example, to represent the air "small" or "medium" or "large" size symbol tag added to the apple, which normally takes three kinds of prior art labeling machines isolated three separate three kinds of label stock and label design. 如果包装厂包装超过一种商标,那么设备结构将变得复杂。 If more than one trademark packaging packaging plant, the device structure becomes complicated. 该标签添加设备是昂贵的并且需要维护,并且需要分选机具有大量的物理空间,由此限制包装操作将其产品放置的位置从而进一步包装产品。 The tag adding apparatus is expensive and requires maintenance, and need sorter having a large number of physical space, thereby limiting their products placed in the packaging operation to further position the packaged product. 本发明有助于仅采用一种贴标签机和一种标签设计以在上述实例中进行相同的贴标签操作。 The present invention contributes to only use a labeling machine A label design and perform the same labeling operation in the above example.

[0059] 广泛使用类型的产品贴标签机使用旋转波纹管添加器。 [0059] The types of products widely used in the labeling machine using a rotary bellows adder. 有利地,在创造“飞速地” 添加可变编码的系统时,需要最小化对现有产品贴标签机作出的任何改进。 Advantageously, in the creation of "fast to" When you add a variable coding system, need to minimize any improvements made to the existing labeling machine product stickers. 类似地,必须保持现有贴标签机的运转速度。 Similarly, it is necessary to maintain the operating speed of the conventional labeling machine.

[0060] 本发明解决“飞速地”添加可变编码信息的问题。 [0060] The present invention solves the problem of "fast to the" Add Variable encoded information. 不需要对现有旋转波纹管添加器进行明显的改进。 Does not require conventional rotary feeder bellows obvious modifications. 不需要减小贴标签的速度。 No need to reduce the speed of labeling. 在优选实施例中,本发明使用一个或多个激光输出光束穿过该标签的背表面或反面(其上承载有粘合剂层),穿过标签基板,使图像形成在标签的前部或可见表面。 In a preferred embodiment, the present invention uses one or more laser output beam through a back surface or back (carrying thereon an adhesive layer), through the label substrate, the label image is formed in the front portion of the tag or visible surface.

[0061] 现有技术采用各种尝试以满足对更多种标签和可变信息的不断增加的需求。 [0061] prior art, various attempts to meet the demand for more labels and increasing the variable information. 现有技术的一种方案(美国专利6,179,030)是将产品贴标签机定位在具有一定尺寸的设备的下游,使得所有标签都表示相同尺寸的产品。 One solution in the prior art (U.S. Patent No. 6,179,030) the product is a labeling machine positioned downstream of the device having a size such that all labels refer to the same sized products. 当然,该方案需要改进传送设备的代价并且受限于具有一定尺寸信息的应用。 Of course, this solution needs to be improved and the cost of transmission equipment having a size limited to the application information.

[0062] 现有技术的另一种尝试方案为在将标签传送至波纹管末端之前(参见美国专利6,257,294)将可变的编码信息添加至前或可见标签表面。 [0062] Another prior art attempt to program the label to the transmitting end before the bellows (see US Patent No. 6,257,294) will be added before the variable coding information or a visible label to a surface. 采用该尝试方案的难度在于随着标签从标签承载带传送至波纹管的末端而将标签扭转和弯折的同时进行标签打印。 The difficulty of using this scheme is to attempt to print labels as the label tape from the label carrier transport to the end of the bellows and the bending and twisting of the label simultaneously. 提供空气流的复杂阵列以尝试控制该标签并且使墨水干化。 Providing an array of sophisticated attempt to control the air flow to the label and the ink drying. 这里,申请人已经研究过该设备,申请人认为该方案在商业上还没有被接受。 Here, the applicant has studied the device, the applicant believes the program has not been accepted commercially.

[0063] 另一种可能的方案是在将标签传送至旋转波纹管的点的上游处将可变信息添加至标签。 [0063] Another possible solution is to transfer the label to the upstream of the rolling bellows of the variable point add information to the tag. 这种方案的难度在于需要使用传感器和定时装置,由此会明显增加成本。 Difficulty with this approach is the need to use a sensor and a timing means, thereby significantly increasing the cost. 例如,为了检测M项产品的可变信息,并且能够将新打印的标签添加至一件以M个“槽”远离已经贴标签的产品,需要使用更多的内存和复杂的定时和同步线路已确保将正确的信息添加至正确的产品;这些的成本可受到控制。 For example, in order to detect the product of the variable item information M, and can be added to a new printed labels to the M "slots" has been away from the tagged product, it requires the use of more complex and memory circuit has ensured the timing and synchronization the correct information is added to the right products; these costs can be controlled.

[0064] 本发明克服现有技术的尝试中的上述难点。 [0064] The present invention attempts to overcome the above difficulties of the prior art. 本发明避免了重新构造由美国专利6,179,030所需的定尺寸和传送设备。 The present invention avoids re-configuration required by U.S. Patent No. 6,179,030 sized and conveying device. 本发明与美国专利6,257,294直接比较可知,在将该标签传送至旋转波纹管的末端之后将可变编码信息添加至该标签,并且避免在现有技术方案中存在的问题。 U.S. Patent No. 6,257,294 and the present invention is directly compared, then transferred to the variable rotational end of the bellows is added to the encoded tag information, and to avoid the presence in the prior art embodiment the label in question. 此外,本发明进一步与美国专利6,179,030直接比较,通过使用立刻与本发明的新颖标签叠层反应的一个或多个激光束避免了使用喷墨和所需的干燥时间。 Further, the present invention further direct comparison with U.S. Patent 6,179,030, by immediately using the present invention with a novel label laminate of the reaction to avoid or more laser beams and the drying time required for the ink jet. 本发明也通过在将标签添加至适当产品之前立刻添加可变编码信息来避免使用高成本的检测和定时线路。 The present invention is also variable by adding the encoding information immediately before adding the label to the appropriate products to avoid the use of costly and timing detection circuit.

[0065] 本标签层叠发明尤其与美国专利申请No. 11/069,330 (2005年3月1日提交,名称为“Method Apparatus for Applying Variable Coded Labels to Items ofProduce")所公开的系统一起使用,该申请(' 330申请)的完整内容引用结合于此。 [0065] The present invention is particularly laminated labels and U.S. Patent Application No. 11 / 069,330 (March 1, 2005 filed, entitled "Method Apparatus for Applying Variable Coded Labels to Items ofProduce") for use with the disclosed system, the entire contents of which application ( '330 application) is incorporated herein by reference.

[0066] 本发明仅需要对标准旋转波纹管添加器进行微小的改进。 [0066] The present invention only requires a standard rotary feeder bellows minor modifications. 本发明没有使用需要较长干燥时间的墨水。 The present invention does not require the use of a long ink drying time. 本发明在每个标签正在移动的同时添加信息,但是在相对稳定的位置, 在标签已经被传送至波纹管末端之后,最大化图像清晰度。 While the present invention is to add the information for each tag is moving, but in a relatively stable position, after the label has been transferred to the end of the bellows, to maximize the sharpness of the image. 本发明能够以与现有旋转波纹管标签添加器的最大速度相匹配的速度形成图像。 The present invention is capable of forming an image at the maximum speed of the rotating speed of the conventional bellows adder tag matches.

Labeled with the labeling station between the corrugations to be nearly constant speed mobile.

[0130] 因此,该材料必须反应于激光能量并且以小于规定的时间标记该实例。 [0130] Thus, the material must response to laser energy and less than a predetermined time mark that instance.

[0131] 用于(X)2和二极管激光系统的典型激光系统规格在下述部分中列出。 [0131] Specifications for a typical laser system (X) 2 and the diode laser systems are listed in the following section.

[0138] 使用具有盲射热涂层的反射件元件 [0138] reflector element having a thermal coating blindfire

[0139] 下述方法说明如何使用反射性涂层、表面或颗粒来优化可用激光能量,相应于可变编码层叠标签,使用本发明“飞速地”应用至新鲜产品。 [0139] The following method illustrates how the reflective coating, or particle surface to optimize the available laser energy, corresponding to the label laminate variable coding, the present invention is the use of "fast to" applied to the fresh produce. 与图5A和10A-10F相结合地部分说明反应性材料。 FIGS. 5A and 10A-10F illustrate the combination of partially reactive material. 这可采用各种类型的激光实现,具体地说(X)2和基于二极管的激光。 This may be used to achieve various types of laser, in particular (X) 2-based laser diode.

[0140] 通过优化地选择材料和承载层叠标签的材料的涂层,激光能可向后导引入标签以有效地增加曝光时间。 [0140] By optimizing the choice of material and the coating material carrying the label laminate, the laser can be turned back into the label to effectively increase the exposure time. 因此,标签所暴露的整体能量密度得以改善并且通过激光产生的最终标记较暗或者可以更大的速度实现类似的标记。 Thus, the energy density of the entire label is exposed is improved and eventually generated by the laser marker may be darker or more speed achieve similar numerals.

[0141] 随着光与给定材料交互,其将被反射、传送或被吸收。 [0141] As the light interacting with a given material, it will be reflected, transmitted or absorbed. 添加至该标签表面的热变色材料已经选择为吸收激光的能量。 Added to the label surface of the thermochromic material has been selected for the absorption of the laser energy. 即使如此,50%或更多的激光能量会损失(S卩,传送或反射)。 Even so, 50% or more of laser energy is lost (S Jie, transmitted or reflected). 因此,优选地设计标签承载器的表面以将尽可能多的激光能量返回至标签的表面。 Thus, the surface of the carrier tab is preferably designed to be as much laser energy returns to the surface of the label. 由于可选择激光的不同补偿,所以该材料必须仔细地被选择以相应于所需的激光。 Since the laser beam to select different compensation, so the material must be carefully selected to correspond to the desired laser light.
