Description

[0001] DESCRIPTION

[0002] CAMERA AND ARTIFICIAL INTELLIGENCE ASSISTED DONER KEBAB STRETCH WRAPPING MACHINE

[0003] Technical Field

[0004] The invention relates to an artificial intelligence assisted doner kebab stretch wrapping machine used in the stretch wrapping process of doner kebab products made with red meat or white meat in the food sector.

[0005] State of Art

[0006] In the food sector, doner kebab is a type of food obtained by hanging red or white meat pieces placed on a spit vertically on a doner kebab cooking machine via the spit and cooking them by rotating in front of a heat source.

[0007] In the production of doner kebab, which is commonly cooked in restaurants and eateries in the food sector, after the meat pieces are arranged on the spit, the doner kebab is wrapped in stretch film to protect it from external factors and enable it to be transported until the cooking process. In existing applications, doner kebab stretch wrapping machines are used for the process of wrapping the doner kebab in stretch film. In doner kebab stretch wrapping machines in the prior art, the carriage system performing the stretch wrapping process cannot detect the angle of the conical-shaped doner kebab, and therefore it is not possible to perform the stretch wrapping properly. In some cases, the doner kebab is laid on its side to obtain the appropriate angle for stretch wrapping. However, in this case, as the doner kebab is rotated during stretch wrapping, the doner kebab consisting of minced meat or meat may fall to the ground and be wasted. For this reason, in the state of the art, a need has arisen for a machine that enables proper stretch wrapping of doner kebab in conical form.

[0008] In research conducted in the literature, the document numbered TR2012 / 09417 can be cited as an example of the state of the art. The document relates to a doner kebab cooking device with movable cooking wings, designed to enable fast, economical, and delicious doner kebab cooking in areas where food is produced such as restaurants and eateries. The device basically consists of two movable wings with a curved structure to surround the doner kebab meat fixed on a cooking spit, various numbers of resistors positioned inside the movable wings, and two connection poles to which the electric resistors are fixed.

[0009] Another example of the state of the art is the document numbered TR2022 / 018201. The document relates to a radiant-free gas cooking device designed for use throughout the food sector, particularly for increasing gas combustion efficiency in doner kebab cookers. The device basically comprises a ventilation apparatus with at least one fan providing air and gas circulation, at least one ignition board enabling adjustment of ignition timing, at least one proportional valve positioned between an ignition board and at least one venturi channel for adjusting the ratio of the air and gas mixture entering through the venturi channel, at least one venturi channel positioned behind the ventilation apparatus in which air and combustible gas are mixed, at least one combustion head containing at least one flexible fabric on which at least one electrode is positioned to provide ignition, and a flexible fabric which is a metal knitted cloth capable of withstanding high temperatures.

[0010] As a result, the existence of the above problems and the inadequacy of existing solutions have made it necessary to make an improvement in the relevant technical field.

[0011] Object of the Invention

[0012] The present invention relates to a doner kebab stretch wrapping machine that eliminates the aforementioned disadvantages and brings new advantages to the relevant technical field.

[0013] The main object of the invention is to present a doner kebab stretch wrapping machine that operates on six axes (A, B, C, X, Y, and Z) and is CNC-based in accordance with the angular form of the conical doner kebab, that captures images of the doner kebab via the camera located on it, and that determines the stretch wrapping data by processing these images with artificial intelligence and ensures that the doner kebab is tightly wrapped in stretch film.

[0014] The structural and characteristic features and all advantages of the invention will be understood more clearly by means of the figures provided below and the detailed description written with reference to these figures. Therefore, the evaluation needs to be made taking these figures and the detailed description into consideration.

[0027] Detailed Description of the Invention

[0028] In this detailed description, the preferred alternatives of the doner kebab stretch wrapping machine, which is the subject of the invention are described only for the purpose of better understanding of the subject and without forming any limiting effect.

[0029] Figure 1 shows the general view of the CNC controlled doner kebab stretch wrapping machine, which is the subject of the invention. Accordingly, the stretch wrapping machine in its most basic form is a CNC controlled doner kebab stretch wrapping machine used in the stretch wrapping process of doner kebab made with red meat or white meat in the food sector, wherein; it comprises a chassis (10) positioned on the ground, a stretch holder (80) that moves in the A axis to wrap the doner kebab, an axis carriage (70) that moves the stretch holder (80) up and down in the Z axis, a camera (90) that captures images of the doner kebab and receives dimensional data, and an artificial intelligence assisted control unit (50) that processes the image received from the camera (90) and determines the stretch wrapping program based on this data. On the chassis (10) forming the main structure of the CNC controlled doner kebab stretch wrapping machine, which is the subject of the invention, there is a doner table (20) performing rotational movement. The said doner table (20) carries the doner kebab by performing free rotational movement. The doner table also provides movement in the C axis.

[0030] The stretch holder (80) that performs the doner kebab stretch wrapping process and moves in the A axis, the axis carriage (70) that moves the doner stretch wrapping arm (40) carrying the stretch holder (80) in the Z axis, and the doner table (20) that moves in the C axis enabling the doner kebab to also move in this axis, operate simultaneously.

[0031] The pressure plate (60) that moves the stretch holder (80) in the X axis, the doner stretch wrapping arm (40) that can move in the B axis, and the ability to move the stretch holder (80) in the Y axis, combined with the continuous capture of the doner kebab image via the camera (90) and processing of the captured image with artificial intelligence to determine the stretch wrapping data and program, enable the doner kebab stretch wrapping machine to also operate in an extra 3 axes.

[0032] On the chassis (10), there is a pressure plate (30) that applies a pressing force to the doner kebab to enable it to rotate.

[0033] The doner kebab is placed and fixed on the doner table (20) operating in the A axis located on the chassis. When the start command is pressed for the doner kebab product positioned on the doner table (20), the camera (90) scans the doner kebab and the artificial intelligence-assisted analysis software in the control unit (50) automatically calculates the dimensions of the product. Additionally, a second artificial intelligence algorithm automatically creates the wrapping program according to how many layers the doner kebab will be wrapped in and the wrapping dimensions required for each layer. The wrapping process is initiated with the second start command. Throughout the wrapping process, the doner table (20) operating in the A axis, the stretch holder (80) operating in the B axis, the doner stretch wrapping arm (40) operating in the C axis, the pressure plate (60) operating in the X axis, and the axis carriage (70) operating in the Z axis move synchronously in the CNC logic in a simultaneous manner in the vertical axis from bottom to top and from top to bottom. Thanks to these coordinated axis movements, the doner kebab is wrapped uniformly and homogeneously with the stretch film placed on the B axis. After the main wrapping process is completed, the pressure plate (30) moves downward. When the determined torque value is reached, the axis stops automatically. In the final stage of the process, the axis carriage (70) operates in the up-down direction to complete the wrapping of the lateral surfaces of the doner kebab.
