[0021] The present invention relates to an automated food packaging device that is capable of packing food items with proper sealing without any requirement of skilled persons thereby stores the food item with preservation.

[0022] Referring to Figure 1, an isometric view of an automated food packaging device is illustrated, comprising a platform 101 integrated with multiple suction cups 102, a touch interactive display panel 103 installed on the platform 101, a motorized roller 104 coiled with packing sheet 105, integrated on the platform 101, a robotic arm 106 installed on the platform 101, an artificial intelligence-based imaging unit 107 mounted on the platform 101, a robotic link 108 installed on the platform 101, a motorized cutter 109 integrated on ends of the link 108, a pair of elongated plates 110 arranged on the platform 101 by means of a motorized slider 111, an electronically controlled nozzle 112 configured with a chamber 113 arranged on the platform 101, an ECV (electronically controlled valve) 114 configured with a nitrogen gas compressor 115 arranged on the platform 101, and a speaker 116 installed on the platform 101.

[0023] The proposed device comprises of a platform 101 made up of any material and wooden material alike and assembled with various components associated with the device arranged in sequential manner that aids in packing food. Upon positioning the platform 101 over a fixed surface, multiple suction cups 102 ranging from 4 to 6 in numbers integrated underneath the platform 101 create partial vacuum within the cups 102 upon pressing over the surface by squeezing out air from the cups 102 due to a negative pressure is generated inside suction area. Herein, atmospheric pressure outside the cups 102 presses down low-pressure area inside the cups 102 to generate suction to adhere the surface and affix the platform 101 with the surface thereby accommodating the platform 101 over the surface in an appropriate manner.

[0024] Upon affixing the platform 101 with the surface, the user requires to activate the device manually by pressing a switch button associated with the device and integrated with the platform 101. The button is type of a switch that is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conduction of electricity that tends to activate the device and vice versa. After activating of the device by the user, a microcontroller associated with the device generates commands to operate the device accordingly.

[0025] After activating of the device, the user accesses a touch interactive display panel 103 assembled with the platform 101 to give input commands regarding specifications of a user-desired number of packages requires to pack. The display panel 103 comprises of a LCD (liquid crystal display) works by using liquid crystals that are manipulated by electric currents to control the passage of light through the display panel 103. When an electric current is applied, the liquid crystals align in a way that either allows light to pass through or blocks it, creating the images and colors that is being visible on the panel 103 upon selecting the input regarding the specifications of the user-desired number of packages in the LCD which is further change the electric charge at the location of touch and registered as input in the display panel 103.

[0026] After that the input commands regarding the tools is stored in a database of the microcontroller link 108 ed with the display to process the input. Upon processing the input given by the user, the microcontroller generates and scrutinize a memory unit link 108 ed with the microcontroller to retrieve number of bags needed for the user-specified number of packages. Upon retrieving the number of bags, the microcontroller generates commands to actuate a motorized roller 104 wrapped with packing sheet 105 assembled with the platform 101 to rotate with specified speed to unwrap an appropriate length of the packing sheet 105 as per number of the bags evaluated by the microcontroller. The roller 104 is linked with a motor that is activated by the microcontroller to rotate roller 104 with specified in order to unwrap the packing sheet 105 up to the required length.

[0027] Simultaneously, the microcontroller actuates a robotic arm 106 assembled with the platform 101 for gripping loose ends of the unwrapped sheet 105. The robotic arm 106 comprises of a shoulder, elbow and wrist. All these parts are configured with the microcontroller. The elbow is at the middle section of the arm 106 that allows the upper part of the arm 106 to move the lower section independently. Lastly, the wrist is at the tip of the upper arm 106 and attached to the end effector works as hand for gripping the loose end of the sheet 105. During this operation, an artificial intelligence-based imaging unit 107 integrated with the platform 101 detects dimensions of the sheet 105. The imaging unit 107 comprises of a camera and processor that works in collaboration to capture and process the images of platform 101.

[0028] The camera firstly captures multiple images of the platform 101, wherein the camera comprises of a body, electronic shutter, lens, lens aperture, image sensor, and imaging processor that works in sequential manner to capture images of the platform 101. After capturing of the images by the camera, the shutter is automatically open due to which the reflected beam of light coming from the surrounding due to light is directed towards the lens aperture. After then the reflected light beam passes through the image sensor. The sensor now analyzes the beam to retrieve signal from the beams which is further calibrate by the sensor to capture images of the surrounding in electronic signal.

[0029] Upon capturing images, the imaging processor processes the electronic signal into digital image. When the capturing is done, the processor associated with the imaging unit 107 processes the captured images by using a code of artificial intelligence to retrieve data from the captured image in the form of digital signal. The data is now transmitted to the microcontroller based on which the microcontroller acquires the data and analyze to detect the dimensions of the sheet 105. Upon detecting dimension of the sheet 105, the microcontroller generates commands to retrieve specific distance from where the sheet 105 is to be cut for making the evaluated number of the bags.

[0030] After retrieving the distance from where the sheet 105 requires to cut, the microcontroller generates commands to actuate a robotic link 108 assembled with the platform 101 to place a motorized cutter 109 equipped on ends of the link 108 on the distances of the sheet 105. The robotic link 108 is similar to the robotic arm 106 that end effector of the link 108 position the cutter 109 on the distance of the sheet 105. After that the microcontroller actuates a motor linked with the cutter 109 to rotate the cutter 109 with specified speed requires for cutting the sheet 105 from the retrieved distances in successive manner for making the bags.

[0031] During cutting of the sheet 105, a confocal sensor integrated with the platform 101 detects thickness of the sheet 105. The confocal sensor works by using a point light source to illuminate the sheet 105, with a pinhole placed in front of the detector to only allow light from the focal plane to be detected and calibrates to detect the thickness of the sheet 105. The detected data is then transmitted to the microcontroller where it analyses to detect the thickness of the sheet 105 and accordingly control the actuation of the cutter 109 for cutting the sheet 105.

[0032] Upon cutting of the sheet 105 detected by the microcontroller via the imaging unit 107, the microcontroller generates commands to actuate the robotic arm 106 to place one end of the cut sheets 105 on a pair of elongated plates 110 assembled with the platform 101 with a motorized slider 111. After positioning of the sheets 105 on the plates 110 detected by the microcontroller via the imaging unit 107, the microcontroller accordingly actuates the slider 111 for sliding the plates 110 towards each other for grasping the end of the cut sheets 105. The slider 111 consists of a rail unit that provides a guided path for linear movement. The rail unit usually includes a pair of parallel rails or tracks, along which the slider 111 moves. The slider 111 incorporates a motor and a drive mechanism to generate linear motion, propelling the rail unit to translate the plates 110 towards each other and grasp ends of the cut sheets 105.

[0033] Upon grasping of the ends of the sheets 105 detected by the microcontroller via the imaging unit 107, the microcontroller generates commands to actuate heating unit fabricated with the plates 110 to producing optimum heating effect to the plates 110 for sealing ends of the sheets 105 The heating unit comprises of heating coil that is activated by the microcontroller upon passing of the electric signal to produce heating effect within the plates 110 in order to sealed the grasp portion and obtain a structure of a bag. A temperature sensor, herein integrated with the plates 110 detect temperature of the plates 110. The temperature sensor is equipped with two electrodes utilized to detect the rise in voltage across the electrodes due to heating of the plates 110. The detecting voltage is equivalent to the temperature that is sensed by the sensor.

[0034] After that the sensor converts that detected temperature into electric signals and transmits that signal into the microcontroller. The microcontroller processes and analyze the signal to detect the temperature of the plates 110 and accordingly regulates the actuation of the heating unit and maintain an optimum heat for sealing the sheets 105 end to obtain the bag. After obtaining the bag detected by the microcontroller via the imaging unit 107, the microcontroller generates commands to actuate the robotic arm 106 to place the bag in proximity of an electronically controlled nozzle 112 assembled with a chamber 113 integrated with the platform 101.

[0035] Upon placing the bag in proximity of the electronically controlled nozzle 112 detected by the microcontroller via the imaging unit 107, the microcontroller actuates the nozzle 112 to dispense a pre-fed amount of a user-desired edible mixture in the bag. The nozzle 112, herein discloses includes solenoids, piezoelectric actuators, or motor-driven mechanisms that converts electrical signals into mechanical motion. The nozzle 112 is controlled by a control unit that sends electrical signals to the actuation mechanism. The control unit includes a pulse width modulation (PWM) or analog voltage control. The primary function of the nozzle 112 is to control the opening and closing of the nozzle 112’s orifice or aperture. Upon receiving the appropriate electrical signal by the actuation mechanism, it initiates the motion that opens or closes the nozzle 112. This action controls the flow of the mixture through the nozzle 112. The nozzle 112 allows precise control over the flow rate and direction of the mixture.

[0036] By modulating the actuation mechanism according to the desired parameters, the nozzle 112 is capable to regulate the flow and provide accurate dispensing of the mixture in the bag. During dispensing of the mixture, a weight sensor integrated with the chamber 113 detects the weight of the mixture. The weight sensor comprises a weight transducer that convert weight of the mixture into an electrical signal that exert a downward force on the weight sensor. Within load cell of the sensor, there are strain gauges that deform slightly due to weight. The deformation causes changes in electrical resistance within the strain gauges. The sensor then calibrates the resistance to detect weight of the mixture in the chamber 113 and transmitted data of the detected weight to the microcontroller where it analyzes to detect the weight of the mixture in the chamber 113.

[0037] Based on detection, the microcontroller now matches the detected weight with a threshold value pre-fed in database of the microcontroller and upon matching, if the detected weight recedes the threshold weight, then the microcontroller activates a speaker 116 integrated with the platform 101 to notify the user to re-fill the chamber 113 with mixture. The speaker 116, herein includes a diaphragm, which is typically made of a lightweight and rigid material like paper, plastic, or metal. It is designed to vibrate and produce sound waves when electrical signals are fed to it. A voice coil (a tightly wound coil of wire) attached with the diaphragm of the speaker 116. The voice coil is suspended within a magnetic gap. When an electrical current flows through the coil, it interacts with the magnetic field produced by the magnet assembly, resulting in a force that moves the coil. The magnet assembly creates a magnetic field within the speaker 116. When the electrical signal passes through the voice coil, it generates a magnetic field that interacts with the fixed magnetic field produced by the magnet assembly. As the electrical current varies, the magnetic field produced by the voice coil changes, resulting in the voice coil and attached cone/diaphragm moving back and forth. This movement creates pressure variations in the surrounding air, generating soundwaves to generate the audible sound to notify the user to re-fill the chamber 113 to continue the dispensing of the mixture in the bag.

[0038] Simultaneously, the microcontroller actuates an ECV (electronically controlled valve) 114 integrated with a nitrogen gas compressor 115 assembled with the platform 101 for releasing an optimum amount of nitrogen gas in the bag. The valve comprises of a diaphragm that is activated by the microcontroller to open orifices of the valve to release the nitrogen gas from the nitrogen compressor to the bag. During releasing of the nitrogen gas, a flow meter is integrated with the ECV 114 detects the flow rate of the gas. The flow meter operate based on the principle of measuring the rate of gas flow through the gas compressor 115. It typically consists of a sensing element, such as a turbine or a paddle wheel that is placed in the path of the gas. As the gas flows, it imparts a force or rotational motion on the sensing element, which is then converted into an electrical signal proportional to the flow rate. This signal is further processed by the microcontroller to detect flow rate of the gas and accordingly directs the ECV 114 to release the gas in the bag. After that the microcontroller actuates the robotic arm 106 to grip the filled bag and place in between the plates 110 for sealing other ends of the bag in view of collecting the user-specified packaged packets of the mixture.

[0039] A battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate functions.

[0040] The present invention works best in following manner that includes the platform 101 developed to be positioned on a fixed surface where the suction cups 102 adhere to the surface for securing the platform 101 on the surface. The user now access the touch interactive display panel 103 to provide input specifications regarding a user-desired number of packages to be packed, based on which the microcontroller linked with the display panel 103 processes the specifications for evaluating number of bags required for the user-specified packages. After that the motorized roller 104 coiled with packing sheet 105 is actuated by the inbuilt microcontroller to rotate for unwrapping an appropriate length of the sheet 105 followed by actuation of the robotic arm 106 to acquire a grip of loose ends of the unwrapped sheets 105. Also, the artificial intelligence-based imaging detect dimensions of the sheet 105, based on which the microcontroller evaluates particular distances from where the sheet 105 is to be cut for obtaining the evaluated bags, followed by actuation of the robotic link 108 to position the motorized cutter 109 integrated on ends of the link 108, over the distances, succeeded by synchronized actuation of the cutter 109 to cut the sheet 105 for obtaining the bags. After that the microcontroller directs the arm 106 to position one end of the cut sheets 105 on the plates 110, followed by actuation of the slider 111 to translate the plates 110 towards each other, for grasping the ends, succeeded by actuation of a heating unit for providing an optimum heating effect to the plates 110 which in turn seals the grasped ends, thereby attaining a structure of a bag, After that the microcontroller directs the arm 106 to position the bag in proximity to the nozzle 112, followed by actuation of the nozzle 112 to dispense a pre-fed amount of the mixture into the bag. Also, the ECV (electronically controlled valve) 114 actuated by the microcontroller to release an optimum amount of the nitrogen gas into the bag, for preserving the mixture, and then the microcontroller directs the arm 106 to grab the filled bag to place in between the plates 110 that is actuated by the microcontroller to seal other ends of the bag, thereby allowing the user to collect the user-specified packaged packets of the mixture.
