    System to control the quality of packaging of a product. The present invention relates to a system for controlling the quality of packaging, comprising: a conveyor means for transporting transparent trays, comprising a pair of discontinuities on its surface; a first chamber and a first source of illumination, arranged on the conveyor means, oriented towards the first discontinuity; a second chamber and a second source of illumination, disposed under the conveying means, oriented towards the first discontinuity; a third chamber and a third source of illumination, respectively arranged above and below the second discontinuity and facing said second discontinuity; and a processor module configured to determine if a packaging failure exists, based on the images captured by the first, second and third cameras and pre-set packaging quality parameters.

    Thus, on a mechanical level, the system of the present invention comprises two independent stations, one for the dry zone and one for the wet zone, which can be combined to offer a comprehensive packaging quality control solution. The stations have in common the following elements:
    5 a) encapsulation means (20, 26) to protect the internal elements of the system, mainly the image capture zone;
    b) conveyor means (21) for transporting the trays, as for example by means of a guide rail system, conveyor belt or roller assembly.
    c) inspection means (22,23) of artificial vision in both areas, but with different characteristics, in the configuration of cameras and lighting sources;
    15 d) means of expulsion (24.25) of defective product, but with different characteristics in both areas.
    The encapsulation means provided in both stations can have different types of guards or protections, fixed or mobile (practicable) with interlocking, in
    20 function of the periodicity with which it is planned to access the different elements of it. Thus, the mobile protection with interlocking, according to one of the embodiments, is fixed by means of unions that require the use of a specific key for its removal.
    The encapsulation means (20) of one of the embodiments of the invention, consist of
    25 practicable protections installed in the artificial vision inspection system made of stainless steel. Said protections allow, on the one hand, to eliminate interference with ambient light and, on the other hand, allow rapid access to the interior of the station using a handle (27). To facilitate the opening of this protection, one of the embodiments of the invention has at least one gas spring.
    30 On the other hand, the fixed interlocking protections (26), which according to one of the embodiments are made of stainless steel, are anchored by bolted joints that require the use of a specific tool for their removal. These fixed protections are suitable, for example, to be associated with the ejector means of the station
    35 of humid zone.

    pneumatic pressure for appropriate. Thus, one of the embodiments of the invention comprises precise control means for the air and the pressure of the pneumatic cylinder, for example by means of an electrovalve (63) located as close as possible to the cylinder. The control means may also comprise one or more flow regulators (64) to control the speed of the cylinder with greater precision.
    The above-mentioned pneumatic means, both for the expulsion means of the wet zone station and for the dry zone station, is contemplated in one of the embodiments of the invention, which are controlled by a pneumatic system. The pneumatic system comprises a pair of solenoid valves, one for each ejector, and a maintenance unit. This maintenance unit, according to one of the embodiments of the invention, comprises: a pressure exhaust valve that allows to close the air flow in the circuit manually; a filter / regulator unit to clean any impurities present in the air and regulate the flow rate; a pressure switch or pressure switch to indicate the air flow available at all times; and one or several electric shut-off solenoid valves so that, in an emergency, by pressing a safety button and pressing the safety mushroom, these valves will be responsible for expelling all the air that may be in the circuit.
    The air supply in the system is carried out, in one embodiment of the invention, by means of a tube coupled between the pneumatic connection of the system and a socket type coupling arranged on one side of the box where the maintenance unit is located. In the lower part of the box, the outlet fittings with which the ejector solenoid valves and an exhaust / silencer are fed are arranged.
    Figure 7 shows the regulation of the Artificial Vision System. The artificial vision system formed by the cameras and lighting sources, whether the wet zone, the labeling control zone, the sealing control zone or any combination thereof, is coupled to a support structure (71 ) mounted on the conveyor means. The structure, preferably cubic, is raised on four corners fixed to the conveyor means by means of guides (72) that allow some adjustment. The different positions that the support structure can adopt are not totally free, but are limited to the possible displacements by said guides that link it to the conveyor means. The position of the structure is fixed by means of clamps, so that only by loosening said clamps can the position of the structure be modified and the clamps again tightened in the new position of the structure so that it is fixed. fifteen

    of trays transported by the conveying means. The two rods of each of the two sets serve as a guide to a second rod (92) perpendicularly coupled to both by the corresponding clamps (93). This second rod can be adjusted vertically by loosening the clamps and moving along the rods 91, but always staying in a plane parallel to the base. In the second rod coupled to each of the two sets of rods, a photoelectric cell (90) is coupled by means of fixing elements, preferably a clamp, which allow its adjustment in any position along the second rod. Thus, by combining the rods set forth above, the position of the photoelectric cells in the Z and X axes can be regulated.
    Figure 10 shows an embodiment of the invention, additional or alternative to that of Figure 9, with a particular configuration of the tray detection system, where the pair of photoelectric cells (90) is arranged on both sides of the conveyor means for detect the passage of transported trays. Specifically, one of the embodiments of the invention contemplates a pair of rods (101) vertically coupled to both sides of the conveyor means. The photoelectric cell on each of the two sides of the conveyor means is joined in solidarity with a second rod (102), which can be coupled to the first cross-shaped rod by means of a clamp (103), so that the second rod and the photoelectric cell can adjust its position in the Z and / or X axes by loosening the clamp and displacing the first and / or second rod.
    The inspections carried out in the artificial vision system on the transparent trays, transported by the conveyor means, are grouped into 3 vision functions, one for the dry zone of labeling control, another for the dry zone of sealing control and another for the wet one. Thus, the artificial vision processor works with different vision functions for each of the mentioned areas.
    In one of the embodiments of the invention, referred to the wet zone, the packaging quality parameters configured in the associated vision function in the processor module comprise product quality parameters comprising one or more of the following inputs and outputs: the input parameters may comprise a minimum area from which it is detected as border meat; a binarized threshold of meat at the edge of the image; a minimum size of dark foreign bodies to be detected in mm2; a measure of container height in mm; a measure of the width of the container in mm; a maximum distance that must be between the product and the edge; a
