    PAN BAR SURFACE CUTTING MACHINE DESCRIPTION
    OBJECT OF THE INVENTION
    The present invention can be included in the technical field of tools and machines that allow surface cutting of bread sticks in an industrialized manner.
    More specifically, it is a machine that allows robotizing the superficial cut that must be made on the bread sticks before the cooking process.
    BACKGROUND OF THE INVENTION
    The cuts that are made on the surface of the bread before baking, in addition to having a decorative purpose, have a functional purpose.
    The decorative purpose is due to the fact that these cuts provide the bread with the definitive image of the product and therefore make it more palatable to the consumer. The functional purpose is because they allow the bread to increase in volume and expand while baking without breaking or cracking on the sides or base.
    During cooking there is an expansion of carbonic gas due to the pressure and accelerated work of the yeast. When said expansion finds a weak point through which to go outside it is possible to favor the last fermentation inside the oven and a correct baking of the bread. The deeper the cuts the more the bread opens when it is baked and will have more crust.
    Currently the cuts are made manually so that the knowledge and experience of the baker are essential to achieve a good result. Each operator trained and experienced in this process obtains a different result.
    The tool that is generally used to perform this operation is a cutting blade that comprises a sharp blade to make clean and perfect cuts, applying a
    firm and determined pressure ensuring that the cuts are equal in depth and length.
    Depending on each type and shape of the bread and the baker, a number of different cuts are made and with a different trajectory.
    5
    The fact of making the cuts in a traditional way has a series of disadvantages that, although they are treated in such a way that they have the lowest possible impact on the product, they are not able to eliminate their effects in the production chain. The main problems are the precision and the low repeatability of the cut, the adaptation to the variations of the mass, the presence of foreign objects and the possible lack of hygiene.
    The manual cutting operation does not allow obtaining accuracy and repeatability and as a consequence there is always a deviation from the definition of cut for each product. A person is not able to make a cut, in a reasonable time, that fits 15 to the defined trajectory of a bar and in addition, as previously mentioned, each operator executes the operation differently from another. Therefore, an optimal cooking result is not achieved. In addition there are also deviations in the trajectory of the cut that affect the aesthetics of the bar.
    20 An operator has many difficulties to adapt to the variability of the dough when executing the cut. A bar in a production process has an important variation that greatly hinders the cutting operation. This is inevitable since it is characteristic of the product's characteristics. Therefore, the operator must adapt to differences in position, size and shape. These difficulties are not overcome by the operator in a good part of the production.
    Although preventive measures are rigorous, they are still a manual task and therefore subject to errors, forgetfulness or delays caused by the person's mood. The absence of foreign objects in the bread cannot be guaranteed 100%. Although there are 30 scanners of metal objects, any other object can become detached from the operator's clothing.
    Undoubtedly, the presence of a person in the cutting operation involves contamination risks that cannot be fully controlled, although thanks to the cooking process
    they will never have any impact on health.
    DESCRIPTION OF THE INVENTION
    The present invention describes a surface loaf cutting machine that automates the cutting operations performed on the bars before starting the bread baking process.
    The use of the described cutting machine allows to solve the problems of the methods used in the state of the art. Especially the problems related to possible human failures during the cutting operations and the little repeatability of the cuts made by different people and even by the same person.
    The machine basically has a scanning station and a cutting station, a control unit and at least one worktable on which the bread sticks are placed in a specific position, which can be moved between the station of Scanning and cutting station.
    The scanning station incorporates scanning equipment that is intended to scan the 20 loaves of bread, when the worktable with the bars is in said scanning station, to obtain three-dimensional images of the position and geometry of the loaves of bread of that work table, which are sent to the control unit, and the cutting station incorporates a cutting equipment intended to make superficial cuts on those bread sticks, when the work table with the bread sticks has moved to said cutting station.
    The type of surface cut to be practiced on the bars is established and selected in the control unit according to the type of bar to be obtained. The direction and depth of the cutting paths to be practiced on the bars by means of the cutting equipment, will be carried out depending on the position and geometry of the images of the bread bars previously scanned by the scanning equipment.
    Thus the control unit is connected to the scanning station and the cutting station, and is intended to receive signals from the image of the bread sticks obtained by the equipment

    scanning, and to send signals to the cutting equipment that include cutting paths to be practiced on the scanned bread sticks according to a predefined direction and depth in the control unit.
    Preferably, the machine of the present invention has a plurality of work tables so that the surface cutting process of bread sticks is continuous and thus optimizes production.
    In general, in a continuous process, the work tables arrive at the machine with the loaves of bread positioned on them from the fermentation chamber, and reach the scanning station, and then they can be moved manually, or preferably in an automated manner, by means of a transmission element towards the cutting station.
    In accordance with the object of the invention and to ensure that the cut of each loaf of bread fits perfectly to its morphology, an image of the loaves of bread arranged on the worktable is taken at the scanning station. The scanning equipment has, for imaging, preferably at least one 3D camera and one line laser, which can be mounted on a travel car, preferably motorized, as well as the scanning station can have a guide on the one that mounts the car with possibility of displacement.
    The guide extends along at least the length of the worktable, in such a way that the car that mounts the 3D camera and the line laser travels throughout the guide with the line laser oriented towards the worktable. I work to get a complete scan of the bread sticks. The image of the bars obtained by the 3D camera and line laser assembly is sent to the control unit.
    The cutting equipment can incorporate at least one articulated arm robot that is provided with a cutting element that is responsible for making the surface cuts on the bread sticks, preferably the cutting equipment will comprise several robots that allow to reach all the bars located on the same work table. Each robot will execute the surface cutting paths ordered by the control unit on the bread sticks based on the images taken by the 3D camera.
    The cutting element mounted by the robot can be, for example, an ultrasonic device or a motorized blade, without ruling out other solutions.
    The cutting station can incorporate a gantry on which the cutting equipment is mounted, under which 5 work tables with bread sticks are placed. The robots that constitute the cutting equipment are distributed in the portico in adequate number and form to be able to reach and practice the superficial cuts of all the bread sticks located on the work table.
