    Labeling method for fish, crustaceans, molluscs and cephalopods, whole or in portions, consisting of the recording of text or figures directly on the skin of the piece by the heat from a source of laser radiation of low intensity carbon dioxide. The graduation of the intensity of the radiation allows the marking without affecting the taste and food properties of the marked piece and avoids the use of elements such as plastics and cartons, which pollute the environment.

    [0004] SECTOR OF THE TECHNIQUE
    [0005]
    [0006] This invention belongs to the industrial sector of packaging / or processing of fresh fish.
    [0007] This system consists of the identification of all types of fish, crustaceans, molluscs and cephalopods by applying a low intensity carbon dioxide laser beam to the skin of the element, either in the head, back or tail, or in pieces of These, applicable in fish packaging industries.
    [0008]
    [0009] BACKGROUND OF THE INVENTION
    [0010]
    [0011] Up to now the state of the art in this sector uses as a labeling system the insertion of a tag of plastic material in the gill of the animal, which only contains the brand of the company, has an inefficiency by detachment of the same before reaching the consumer of 70%, and generates a significant annual amount of non-recyclable plastic waste, being small.
    [0012] The base on which innovates is the machine of marking by laser and use of patented food pigments with the number ES 2284407 A1, which is used for the marking of fruit pieces and hams.
    [0013] The aforementioned machine presents the problem that although it is used for marking different pieces of fruit, when applied to the skin of a fish, the intensity of the marking is very weak, erasing almost in its entirety and becoming imperceptible to simple seen a few hours.
    [0014]
    [0015] EXPLANATION OF THE INVENTION
    [0016]
    [0017] The innovation provided by the proposed system is the replacement of the laser head with another of GREATER power, which achieves a perfect marking on the surface of the skin of the fish, below the scales, and without altering the surrounding meat with the skin marked.
    [0018] It is convenient to locate as a previous step of the piece of fish before the marking of the laser, by a jet of air under pressure in the area of the marking, to eliminate the excess of humidity, both external, and the slime that the fish gives off from the moment of death.
    [0019] For this, the laser head is replaced by a low intensity carbon dioxide head, with a voltage range of between 140 and 225 watts, and a marking exposure in the range of 0.4 and 1.3 seconds per piece of fish. With this modification we eliminate the need to apply any food dye to reinforce the marking, since with the only exposure to the laser beam a perfect impression of the text and drawing of free choice and size is achieved, and in the desired place (head, spine or tail). As advantages over the current technique improves the labeling system in the following points:
    [0020]
    [0021] - This marking does not alter the fisico-chemical conditions of the fish.
    [0022] - It is indelible, perfectly supporting the expulsion of slime by fish from its death, low temperatures and extreme humidity throughout the process of traceability, until arriving in perfect condition to the final consumer, providing all guarantees that it has all the information determined by law. Currently this information is on a label in white cork container boxes, and are susceptible to substitution by fish from other sources to be cheaper, deceiving the consumer.
    [0023] - Possibility that in addition to putting logo and trade name, it allows adding the name of the species, origin, and most importantly, the date of packaging and / or consumption of each unit, reaching this information to the consumer, with no possibility of fraud .
    [0024] - It does not pollute the environment by not using any physical material (plastic, paper, etc).
    [0025] - In packaging companies that carry out the cutting of fish for sale, it also allows the perfect identification and traceability of the pieces of fish individually with this system, so far possible non-existent.
    [0026]
    [0027] PREFERRED EMBODIMENT OF THE INVENTION
    [0028]
    [0029] As it is possible to observe in the attached figure, the integral fish coding system, object of the present invention, comprises, at least:
    [0030]
    [0031] - a modular chassis [1];
    [0032] - linear transport means [2], comprising at least:
    [0033] or a roller path, where said rollers are of a material not harmful to the fish.
    [0034] - lifting means [3], comprising one of the means selected from:
    [0035]
    [0036] or a pellet elevator, where the speed of advance, the speed of rotation of the pellets and the size of pellets are variable, depending on the type of fish or production need;
    [0037]
    [0038] or a cup lifter, of the type in which the cups are made of plastic material and the size of the cups variable depending on the type of fish or production needs;
    [0039] - calibration means [4], comprising, at least:
    [0040]
    [0041] or a color camera;
    [0042]
    [0043] or a volume chamber;
    [0044] where said cameras are located in a single ventilated cabinet, and where the cameras form an artificial vision system for the recognition of the caliber of the fish, and where these calibration means are connected to a personal computer;
    [0045] - Pressurized air expeller [5] to be applied to the fish before marking.
    [0046] - higher power laser marking media [6].
    [0047] - output conveyor means [7].
    [0048]
    [0049] The method of integral coding of fish, comprises, at least, the following stages:
    [0050] - Stage of transport, where the fish arrives, and in which it is possible to make a previous selection.
    [0051] - Elevation stage: After the transport stage, the fish pass to an elevator, through which they enter, transporting themselves to the calibrator.
    [0052] - Calibration stage: For every two streets, a color camera and a volume camera are installed, transmitting the information to a computer; this information is stored so that the data of the processed item (traceability code) is known, since it must transmit this information to the laser marking equipment, so that it knows which piece has to be marked and what information must be marked on the piece .
    [0053] Unitarily, each fish will go through the calibration system, which will identify the quality of the fish through the cameras, passing them to the next stage.
    [0054] - Stage of elimination of excess humidity with air under pressure on the area to be marked.
    [0055] - Higher power laser marking stage: With the information obtained in the calibration stage, the selected text in the area of the desired fish will be marked by laser.
    [0056] - Exit stage.
    [0057] The system is a set of media that are interrelated, so they have to work under the same speed parameters for the method to be carried out. This speed is variable depending on the species and size of the fish and the production needs.
    [0058]
    [0059] BRIEF DESCRIPTION OF THE DRAWING
    [0060]
    [0061] As an attached drawing a sketch of the marking system and a photograph of a seabass after a laboratory test, in which the logo and name of a company, the name of the fish has been marked on the spine by exposing the fish to the laser beam , the FAO extraction zone and the country of origin. You could have added the weight, the date of extraction and the expiration date, etc.
