    COLOR MARKING FOR LOGS
    Object of the invention
    The object of the present solution is a method for coloring logs. The solution to be presented also relates to a liquid log marking color intended for color marking of the logs. A further object of the present invention is a method for tracking the logs marked with a marking color.
    Background of the Invention
    Mechanical harvesting methods often involve the harvester applying the desired color marking to the end of the log cut, which corresponds to, for example, the log type of log, such as saw logs, or some other feature of the log, depending on agreed practices. Color marking allows the log type of timber, or other feature, to be identified during subsequent processing or transportation of the log, for example, when collecting timber to a forwarder, and thus helps in sorting the log.
    Color marking can be done with a color marking apparatus located on the harvester head of the harvester, which prunes and breaks the tree trunks and usually also cuts down the tree. The color marking may be made at the end of the log on the cutting surface, for example, by spraying the toner using one or more nozzles or by passing the toner through the saw flange of the sawing device to the cutting surface. Also known are color marking devices which can be used to mark a log with a readable color marking, which can be used to uniquely identify the log and / or to include information about the log, for example the aforesaid timber species or other characteristic. The color notation can be 30 text, numbers, or a pattern encoded in a predetermined manner.
    The color marking pattern may, for example, represent a unique serial number or identifier.
    Some examples of known color marking devices are disclosed in WO 2012/052549 A1. An example of a known dye for use in color marking devices is disclosed in WO 03/034809 A1.
    20175443 prh 16 -05- 2017
    Adding the color markings described above to the logs also allows the logger itself or the logging area or logging area to be harvested to be logged. It is also possible for the log, harvester, stand or harvesting block data to be stored elsewhere, for example in an information system, and this information can be associated with that log by means of the so-called unique identification.
    It will be appreciated that environmental conditions, such as rain, frost and sunshine, will cause problems in how well the color marking is maintained on the 10 dust cutting surface, which will also be affected by the characteristics of the log cutting surface itself. It is clear that, for the reasons mentioned above, complex color markings are not always reliably readable from a log, for example, in a sawmill, and problems with color markers can also cause problems with color marking and clarity.
    On the other hand, when the color marking is based solely on the perceptible colors of the human eye, it is not possible to use a single color variation, e.g., to identify the harvester used, since there are a limited number of commonly used color variations. In addition, these same color variants are also commonly used to denote the characteristics of a log, so that a single log alone does not make it possible to determine, for example, at a sawmill, what the log is for and what it is intended to indicate.
    BRIEF SUMMARY OF THE INVENTION
    A method of marking the logs with a color marking 30 according to the disclosed solution is set forth in claim 1. The liquid marking color of the logs according to the present solution is set forth in claim 13. The method of the present solution for tracking logs marked with color is set forth in claim 15.
    20175443 prh 16 -05- 2017
    In the method according to the disclosed solution, the logs are marked with a liquid marking ink. That marking color shall contain at least one additive or combination of additives which distinguishes the characteristics of the marking color from the 5 marking colors used for marking the wood, with or without the additive or combination of additives in question, and also with those with different colors and without the additive or combination of additives. In this specification, a marker color containing at least one additive or combination of additives is also referred to as an additive marker color.
    The presence of the additive or combination of additives in the color of the label is detectable by senses or sensing means.
    According to one example, this labeling of the logs is carried out using a batch of a marking ink which is part of a batch of 15 of the same marking color and additionally contains at least one additive or combination of additives while the said batch is without said additive or combination of additives. In addition, the characteristics of the batch in question are also different from those of the said batch. According to one example, the at least one additive 20 or combination of additives is added to a portion of the aforementioned batch to form said batch of product.
    The color of the lot in question corresponds to that of the lot in question, which is the color visible to the human eye.
    According to one example of the disclosed solution, the method produces such markings with a color marking apparatus located at the harvester head. According to another example of the disclosed solution, the method manually generates such markings with the aid of 30 persons.
    According to an alternative to the solution shown, the method selects for logs defined as belonging to a predetermined set of logs. According to one example, in method 35, the logs processed by a predetermined individual harvester are selected for marking. According to another example
    In the method 20175443 prh 16 -05- 2017, the logs that are processed by two or more predefined harvesters are selected for significance. According to a third example, the method selects for logs from a predetermined one or more plurality of stands. According to a fourth example, the method selects for logs from a predetermined one or more harvesting blocks. This predetermined set of logs may also be selected to include only those logs that simultaneously belong to at least two of the above-mentioned examples.
    The liquid log marking color of the present solution contains at least one additive which distinguishes the marking color of the markings used to mark the timber, which are of the same color and without the additive or combination of additives and also with those of the same color and without the additive. or a combination of additives. The presence of the additive or combination of additives in the color of the label is detectable by senses or sensing means.
    According to one example, said ink color constitutes a batch of product which is part of a batch of said same ink color and further comprises at least one additive or combination of additives, whereas the said batch is without said additive or combination of additives. Thus, the characteristics of the batch in question are different from those of the batch.
    The method and marking color of the proposed solution have the advantage that prior art marking colors with the addition of the solution 30 and various known marking apparatuses can be used, so that the need for additional investment and the technical modification needs of marking equipment is minimal or non-existent. The solution shown can be applied in such a way that, as before, the logs can be labeled in the desired manner with marking colors, for example, for sorting in a stand.
    20175443 prh 16 -05- 2017
    In the method according to the disclosed solution, to observe the logs labeled with an additive marking color, a set comprising a plurality of color-labeled logs is detected and from that set, the logs having the marking color characteristics corresponding to the predetermined 5 additive marking colors are identified.
    The method further comprises measuring at least one dimension and / or at least one quality property of said identified logs and collecting at least one dimension and / or at least one quality property in the database.
    One embodiment of the proposed solution is that the logs are marked with an additive marking color, but the marking is not necessary or intended to be used for sorting, e.g. Instead, this marking can be used to identify logs, for example in a sawmill. This marking may be used for sorting logs, for example, in a sawmill or elsewhere, such as a timber warehouse or a timber reception facility. Another application of the disclosed solution is that the logs are marked with an additive marking color and the marking is also used for sorting, e.g.
    The method and the additive marking color of the proposed solution can be utilized, for example, to identify the origin of the log, which is also based on the log handling and the sorting mentioned above, for example, in a sawmill or elsewhere.
    The logs labeled in accordance with this solution can be identified so that information collected or measured from them, e.g., dimensions and / or quality characteristics, can be used to provide feedback, evaluation, quality evaluation, statistics or summaries, e.g., in an information system. In this way, information can be provided, for example, on a predetermined set of logs, a harvester, a stand or a harvesting block.
    Detailed Description of the Invention
    In the solution shown, the logs are marked with liquid marking ink. 35 The markings in question contain at least one additive which distinguishes them from those used for marking wood.
    20175443 prh 16 -05-2017 of the labeling colors, with and without the additive or combination of additives. These markings may be of the same color or of a different color, which means the color perceptible to the human eye. The presence of the at least one additive or a combination of several additives in the marking color is detectable by senses or sensing means. In the above-mentioned combination of additives there are at least two additives.
    According to a first example, the additive in question is a reflective body or reflective ingredient which strongly reflects the visible light that is hit and is most noticeable or, for example, visible to the human eye in the dark or in the dark. This is, for example, a reflective ingredient whose presence in the ink color can be detected based on the changed properties of the ink color in terms of reflectivity which is better or greater than other or known ink colors or other batches of the same ink.
    According to another example, the additive is a fluorescent body or component that emits visible light when the additive marker color 20 is illuminated by electromagnetic radiation or ultraviolet light.
    According to a third example, the additive is a fluorescent body or a component that emits electromagnetic radiation that differs from the wavelength of visible light when the additive marker color is illuminated by electromagnetic radiation or ultraviolet light. In the second and third examples above, the properties of the marking color are related to the ability to radiate electromagnetic radiation.
    According to a fourth example, the additive in question is magnetic bodies which are detectable through a magnetic field.
    The properties of the marking color with respect to magnetism are thus noticeable.
    According to a fifth example, the additive is articles, such as felts, crystals, granules or the like, whose presence or absence in the marking color is a noticeable property. According to one
    In accordance with the 20175443 prh 16 -05- 2017 option, these paragraphs are distinguished from the color of the marker color. According to one alternative, the pieces in question also have a recognizable property of color tone.
    In the identification of the solution, and in the examples above, additional light sources and detector means known per se, such as various camera, sensor, imaging or detection devices for detecting electromagnetic radiation, e.g., in the visible light frequency, in the infrared or ultraviolet light, may be utilized. 10 at a different frequency. Also, the aforementioned additional light sources may operate at the frequencies mentioned above and / or, if necessary, cause the marker dye to react in the desired manner to enable identification and the aforementioned characteristics of the marker color may be determined. Ideally, recognition is non-contact and remote. The above-mentioned sensor means or devices may, for example, provide an indication of whether or not the additive in question is detected. Such sensor means or devices may be part of a computer-based system.
    At different frequencies of visible light, different shades of color are detectable by the human eye, 20 which is also the basis for the utilization of known, non-additive marking colors.
    Such sensing means may be devices for detecting the presence of the aforementioned additive using a magnetic field, e.g. based on the generation, change or variation of 25 magnetic fields when the magnetic material affects the magnetic field. Such sensor means may be, for example, a magnetometer or a Hall-based sensor or sensor.
    According to one example, color markings are produced by a color marking apparatus located at the head of the harvester 30. In this case, the marking occurs, for example, on the sawing surface of the log either during, or almost immediately after, the cross-cutting of the log. By means of the harvester head, the harvester at least performs pruning and splitting of the tree trunk into logs of the desired length, representing different types of timber, such as logs or lathe logs.
    20175443 prh 16 -05- 2017
    According to another example shown, the color markings are manually generated by a tool by a person. For example, brushes, paint sprayers, color stamps, paintball guns or spraying equipment can be used. For example, the logs 5 in the stack or in the terrain can be marked manually.
    The marker color additive may be in powder, slate, granular, dry, gel, greasy or liquid form and added to the marker color. The additive in question is added to the marking color e.g.
    during the manufacture of the label in question or when the initial use of an additive free ink is introduced.
    The marking color to which the additive is added may be known or developed for the purpose. The additive in question may be added to a batch of 15 inks which are part of a broader batch of the same ink in the absence of the additive or combination of additives. In this case, the additive marking color of the solution may be formed outside of, for example, the factory that manufactured the batch or based on commercially available or known ink colors.
    For the purposes of this specification, a batch and a lot shall mean a given number of the same color of the mark, which may be divided into separate packages or articles, or a number of packages or products of the same color. 25 Such a specific quantity or set may represent, for example, production over time, products to be supplied, products commercially available or products purchased for use.
    The aforementioned additive may contain ingredients that affect its stability, frost resistance or other properties.
    The detector means described above may be disposed in a location where a plurality or a plurality of logs may be observed which may be color-coded. This location is, for example, a sawmill, a 35 timber warehouse or a timber reception facility.
    20175443 prh 16 -05- 2017
    From the observed set of logs, those with the marking color properties corresponding to the additive marking color of the solution are identified.
    Such detection and identification can be done manually, for example using the senses, in particular visual sense, or using tools based on the above-mentioned sensing means. Preferably, such detection and identification is effected, for example, by the use of automatically operating and / or stationary devices, for example by the operation of devices for transporting or transferring logs. Some examples of these devices are various sawmill conveyors.
    The above-mentioned locations may also have previously known and used measuring devices that measure one or more 15 dimensions or one or more quality characteristics of the logs. Such measuring devices are based, for example, on machine vision. This dimension is, for example, diameter or length. Such quality property is, for example, knottiness, placement of branches on the log, conicity, looping, volume and lumpiness.
    For example, using information systems, the data of the identified logs described above can be stored centrally, separately from the data of the other logs, or in such a way that their data can be separated from that of the other logs, if necessary. This makes it possible to compare the information of the identified logs, e.g., at least one dimension and / or at least one quality property, with the predefined criteria for the logs marked with that additive marking color. This will provide an estimate of the type of logs in question in relation to the criteria mentioned. Such criteria are, for example, recommended or desired values for the aforementioned dimension or quality feature. Such a practice can be used to monitor, for example, the performance of logging, by harvester, by stand, by harvest block or by region, or by doing so for a predetermined set of logs.
    The above detection and identification can also serve as a basis for sorting the logs 35 to determine whether or not the logs are marked with a marker color containing the aforementioned additive. This can, for example, ensure that only logs of a specific origin are accepted for processing. The sorting can be carried out, for example, at a sawmill, a timber warehouse or a timber receiving plant. The sorting is carried out, for example, by means of means for conveying or moving the logs, e.g. by means of conveyors.
    The solution presented is not limited to the above examples or alternatives, which may additionally be combined. The disclosed application of the solution is further defined in the appended claims.
