Description:FIELD OF THE INVENTION

[0001] The present invention relates to an autonomous warehouse package handling device that automate the processes of package classification, secure storage, environmental monitoring, and transport within warehouse environments. More particularly, the invention pertains to a mobile device that is capable of identifying, packaging, and relocating various types of packages including fragile and perishable goods.

BACKGROUND OF THE INVENTION

[0002] In today’s rapidly growing e-commerce and retail industries, efficient warehouse operations have become critical to ensuring timely delivery, order accuracy, and customer satisfaction. Package handling forms the backbone of warehouse logistics, involving activities such as sorting, classifying, wrapping, and transporting goods. As warehouse volumes increase and product diversity grows including fragile and perishable items, the need for precision, speed, and safety in package handling is more important than ever. Ensuring that packages are correctly identified, securely wrapped, and safely routed plays a direct role in minimizing product damage, reducing labor costs, and increasing overall operational efficiency.

[0003] Traditionally, package handling in warehouses is carried out manually by workers using basic tools such as hand trolleys, conveyor belts, and packing tables. Identification is often done through manual barcode scanning, and fragile or perishable items are wrapped or stored with limited consistency and oversight. These methods are time-consuming, error-prone, and not scalable for high-volume environments. Moreover, they lack the ability to monitor environmental conditions, which is crucial for preserving sensitive items. Hence, there is a clear need for a device that is capable of managing diverse package types while minimizing manual intervention and ensuring optimal handling based on package-specific requirements.

[0004] CN101107193B discloses about a layered package handling device for forklifts, reach tracks, stock pickers or stackers, comprising a head that has a series of closely parked suction devices set out in a planer array which are served by a common vacuum chamber, the head able to be carried by forks and the vacuum is supplied by a separate unit mounted on the forklift. In a modification the head is carried on a sub assembly which allows the head to move to one side of the forklift etc.

[0005] US4832204A discloses about a package handling and sorting system which sorts small packages according to destination, segregating those with the same destinations for combined shipments. The system depends on a unique combination of conveying equipment automatically controlled by programmed data processing units which utilize data obtained by scanning electronically readable package labels, as well as other information and detection equipment, to examine packages introduced into the system, and to transfer those consigned to the same location to vehicles routed to such locations. The system also generates an electronic trail of package movements, thus providing the capability to trace packages lost in transit.

[0006] Conventionally, many devices have been developed that are capable of basic warehouse automation such as package transport and barcode scanning. However, these existing devices are incapable of classifying packages based on fragility or perishability, or adapting their handling techniques accordingly. Additionally, these existing devices also lack integration of autonomous navigation, environmental condition monitoring, real-time obstacle avoidance, and comprehensive wrapping and preservation mechanisms for sensitive packages.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of autonomously handling, securing, wrapping, classifying, and preserving various types of packages while navigating a warehouse environment without manual intervention. In addition, the developed device should also ensure accurate scanning and recognition of package data, adjustment of preservation parameters, and seamless integration of user commands and holographic feedback for operational monitoring.

[0009] An object of the present invention is to develop a device that is capable of autonomously navigating a warehouse environment and performs package handling tasks in an automated manner with minimal human intervention.

[0010] Another object of the present invention is to develop a device that is capable of performing accurate identification and categorization of packages using advanced recognition and analysis techniques, thereby supporting tailored handling procedures.

[0011] Another object of the present invention is to ensure proper handling of perishable and fragile packages by implementing automated wrapping, vacuum sealing, and protective packaging processes.

[0012] Yet another object of the present invention is to develop a device that is capable of continuously monitoring internal environmental conditions to maintain optimal preservation parameters and issue alerts in case of adverse variations.

[0021] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to an autonomous warehouse package handling device that is capable of independently navigating indoor warehouse environments while classifying, securing, wrapping, and preserving packages based on their specific handling requirements. Additionally, the present invention is capable of real-time environmental monitoring and obstacle detection to ensure safe and efficient package management, while providing remote user control and holographic visual updates for seamless operational oversight.

[0023] Referring to Figure 1, an isometric view of an autonomous warehouse package handling device is illustrated, comprising a body 101, multiple motorized wheels 102 are arranged underneath the body 101, a securing chamber 103 incorporated within the body 101, a rotating disc 104 is arranged with the chamber 103, rotating disc 104 is equipped with multiple clippers 105 at bottom periphery, a four-bar linkage arrangement 106 installed adjacent to the securing chamber 103, an AI (artificial intelligence) camera 107 installed on the body 101, an L-shaped telescopic link 108 provided inside the securing chamber 103 and integrated with a vacuum unit 109 and a clamping unit 110.

[0024] Figure 1 further illustrates a dedicated storage compartment 111 provided on the body 101, a motorized roller 112 arranged within the securing chamber 103, a motorized blade 113 associated with the roller 112, a scissor lifting arrangement 114 arranged on the body 101 and attached to a platform 115, the platform 115 is installed with a ball caster conveyor belt 116 and wedge-shaped plates 117 with conveyor belts 118, and a holographic projection unit 119 is mounted on the body 101.

[0025] The device disclosed herein comprises of a body 101 developed to be placed on the floor surface of a warehouse. The body 101 is constructed to withstand the typical conditions encountered in indoor warehouse environments, including uneven surfaces, obstacles, and frequent starts and stops. The body 101 is equipped with multiple motorized wheels 102 arranged underneath the body 101 to facilitate smooth and autonomous navigation across the warehouse floor.

[0026] A user is required to activate the device manually by pressing a button installed on the body 101 and linked with an inbuilt microcontroller associated with the device. The button is a type of 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.

[0027] Upon activation of the device, the user is required to access a user-interface installed in a computing unit to provide various operational commands to the device. These commands include initiating movement, allowing the device to start navigating autonomously, pausing operations to temporarily halt movement or package handling, and setting specific destination points within the warehouse for precise delivery or pickup tasks. The computing unit is wirelessly associated with the microcontroller via a communication module which includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module allows the microcontroller to send and receive data to and from the computing unit without the need for physical connections.

[0028] The Wi-Fi module provides connectivity over local networks, enabling real-time communication over longer distances. The Bluetooth module offers short-range, low-power communication, ideal for close proximity. The GSM module allows for communication over mobile networks, facilitating remote monitoring and control from virtually anywhere. This versatile connectivity ensures seamless interaction between the microcontroller and the computing unit.

[0029] Upon receiving the signal from the computing unit, the microcontroller actuates the motorized wheels 102 to maneuver and position the body 101 at the user-specified location within the warehouse. The motorized wheels 102 are a circular object that revolves on an axle to enable the body 101 to translate easily. A hub motor is integrated into the hub of the wheels 102. The hub motor is an electric motor that comprises of a series of permanent magnets and electromagnetic coils. When the motor is activated, a magnetic field is set up in the coil and when the magnetic field of the coil interacts with the magnetic field of the permanent magnets, a magnetic torque is generated causing the stator of the motor to turn and that provides the rotational motion to the wheels 102 to ensure smooth movement of the body 101 as per the user command to position the body 101 near the user-specified location within the warehouse.

[0030] A securing chamber 103 is integrated within the body 101 and designed to temporarily store packages during handling operations. The chamber 103 is configured to accommodate packages of varying sizes and shapes and provides a secure and organized space to hold them while sorting or transporting. A four-bar linkage arrangement 106 is installed adjacent to the securing chamber 103, wherein upon positioning of the body 101, the microcontroller actuates the four-bar linkage arrangement 106 to securely grip packages and position the package within the securing chamber 103.

[0031] The four-bar linkage arrangement 106 comprises of four interconnected pneumatic links forming a parallelogram structure, to provide controlled and precise motion for package handling. Each link in the four-bar arrangement 106 is actuated by a pneumatic unit that extend and retract the links to move the linkage arrangement 106 smoothly. At the terminal end of the four-bar linkage arrangement 106, multiple clamps are mounted to securely grip packages of various shapes and sizes.

[0032] Upon actuation, the pneumatic unit extend/retract the links in a manner to position the clamps near the package placed in proximity to the body 101. The pneumatic unit used herein includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the links. The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air.

[0033] The air compressor is consisting of two main parts including a motor and a pump. The motor powers the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure. The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend. The piston is attached to the links, wherein the extension/ retraction of the piston corresponds to the extension/ retraction of the links to position the clamps in contact with the package.

[0034] Post positioning of the clamps, the microcontroller actuates the clamps to securely grip the package. The clamps are designed with adjustable jaws lined with soft, anti-slip materials such as rubber or silicone to ensure a firm hold on packages of different materials and sizes. The clamps used herein includes motorized actuators, clamp jaws, and a limit switch or sensor. Upon actuation, the microcontroller sends signals to the motorized actuators, usually electric motors or linear actuators, which drive the clamp jaws inward. These jaws close around the package, applying uniform pressure to hold it securely. Limit switches or force sensors detect when the desired grip is achieved and signal the motor to stop for preventing over-compression.

[0035] Once the package is securely gripped, the microcontroller commands the four-bar linkage arrangement 106 to position the gripped package over a rotating disc 104 arranged within the securing chamber 103, for further processing or transport. Upon placing the package, the microcontroller actuates multiple clippers 105 installed at bottom periphery of the disc 104 for securely holding the package.

[0036] The clippers 105 used herein includes a DC motor or servo motor, clipping arms or jaws, a gear assembly, a spring or tension arrangement, and a sensor or limit switch. Upon actuation, the motor drives the gear assembly to move the clipping arms toward each other. The arms securely grip the package using a spring-loaded force to maintain consistent pressure. The sensor or limit switch detects when the clipping arms have fully closed around the package and signals the motor to stop for securely holding the package placed over the disc 104.

[0037] Upon securing the package, the microcontroller actuates an AI (artificial intelligence) camera 107 integrated with an optical character recognition (OCR) sensor installed on the body 101, for scanning and analyzing package codes to determine package types and handling requirements. The AI (artificial intelligence) camera 107 comprises of a high-resolution camera lens, digital camera sensor and a processor, wherein the lens captures multiple images from different angles and perspectives of the package with the help of digital camera sensor for providing comprehensive coverage of the package.

[0038] The captured images then go through processing steps by the OCR sensor to detect and interpret printed or engraved alphanumeric codes, barcodes, QR codes, and other standardized package identifiers affixed to the surface of each package for extracting text, numerical data, and encoded information from the package surface. The OCR sensor utilizes advanced pattern recognition and machine learning protocols to interpret various font types, code styles, and label formats commonly used in logistics environments to find out the letters written over the label present over the packages, and send the detected letters and words to the microcontroller in the form of electrical signals.

[0039] The microcontroller processes the received data from the imaging unit and the OCR (optical character recognition) sensor to determine package types and handling requirements by decoding alphanumeric identifiers, barcodes, or QR codes present on the surface of each package. This data is analyzed in real time to classify the package based on predefined categories such as fragile, perishable, standard, or high-priority, and accordingly initiates appropriate handling protocols.

[0040] An L-shaped telescopic link 108 is provided inside the securing chamber 103, and is operatively integrated with a vacuum unit 109 and a clamping unit 110, respectively. In case the package is determined to be perishable, the microcontroller actuates the telescopic link 108 to extend and position the clamping unit 110 toward a dedicated storage compartment 111 provided on the body 101, for extracting an empty container from the compartment 111 and position the container near the chamber 103. The extension/ retraction of the telescopic link 108 is powered by the pneumatic unit associated with the device which works in the same manner as described above.

[0041] The clamping unit 110 used herein works in the similar manner as described above for the clamps, to firmly hold the container and position the container near the securing chamber 103. Post positioning of the container, the microcontroller re-actuates the L-shaped telescopic link 108 and the clamping unit 110 to grip and place the perishable packages inside the containers. After the package is accurately placed inside the container, the microcontroller actuates the vacuum unit 109 to reduce the internal air pressure of the container, for preserving the perishable contents by limiting exposure to oxygen and contaminants. The vacuum sealing process ensures extended shelf life and safe transit of temperature-sensitive or degradable goods/package.

[0042] The vacuum unit 109 used herein includes a vacuum pump, sealing lid or valve, pressure sensor, and tubing. When actuated, the vacuum pump draws air out of the container through the tubing. The sealing lid ensures no external air enters during the process. The pressure sensor monitors the internal air pressure and sends feedback to the microcontroller. Once the desired vacuum level is achieved, the pump is stopped, and the valve or lid is locked to maintain the vacuum. This extends the shelf life and quality of perishable items.

[0043] Simultaneously, an environmental condition monitoring unit installed on the body 101, comprising temperature, humidity, and air quality sensors, continuously monitors the storage environment. The temperature sensor used herein detect the temperature by optical analysis of the infrared radiation present in the surrounding. On activation, the sensor employs a lens to focus the infrared radiation emitting from the surrounding, onto a detector known as a thermopile. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to detect the temperature of the environment. The measured temperature is then converted into electrical signal which is received by the microcontroller.

[0044] The humidity sensor measures atmospheric moisture by detecting changes in electrical properties due to humidity levels. The humidity sensor comprises of a sensing element (capacitive or resistive), substrate, electrodes, and signal conditioning circuit. In a capacitive humidity sensor, the sensing element includes a hygroscopic dielectric material placed between two electrodes. As atmospheric moisture changes, the dielectric constant of the material shifts, altering the capacitance. In resistive sensor, moisture changes the conductivity of a hygroscopic film, varying resistance. These changes are converted into electrical signals by the signal conditioning circuit and sent to the microcontroller.

[0045] The air quality sensors used herein includes a gas sensor module, and a particulate matter (PM2.5/PM10) sensor. The gas sensor detects volatile organic compounds (VOCs), CO₂, and other harmful gases using a heated sensing element that changes resistance in response to gas concentration. The PM sensor uses a laser or LED with a photodetector to count airborne particles. The air quality data is transmitted to the microcontroller.

[0046] The microcontroller processes the data collected from all the sensors associated with the environmental condition monitoring unit, to determine the internal and ambient environmental conditions within the vicinity of the securing chamber 103 and surrounding operational area. Based on the analyzed data, the microcontroller dynamically adjusts the vacuum pressure within the containers accommodating perishable packages, for ensuring optimal preservation conditions tailored to the specific environmental parameters detected.

[0047] A motorized roller 112 is arranged within the securing chamber 103, and comprising a bubble wrap roll and an associated motorized blade 113. In case the package is determined to be fragile, the microcontroller actuates the roller 112 to rotate and uncoil the bubble wrap. The motorized roller 112 used herein is a mechanical unit designed to rotate on its axis with the help of an integrated electric motor. The roller 112 consists of a cylindrical roller tube that serves as a surface for accommodating the bubble wrap roll. The motorized roller 112 is equipped with an electric motor that provides the rotational power necessary to turn the roller 112. The motor is connected to the roller tube through a drive arrangement, which involves gears, belts to transfer the motor’s rotational force to the roller 112, causing the roller 112 to spin and unwrap the bubble wrap roll.

[0048] Simultaneously, the microcontroller actuates a DC (direct current) motor connected to the rotating disc 104 to rotate the disc 104 along with the package at a pre-defined RPM (Revolutions Per Minute) for wrapping the unwrapped bubble wrap roll over the package. The disc 104 rotation ensures uniform angular motion of the package, for enabling the bubble wrap dispensed from the motorized roller 112 to be applied evenly across all exposed surfaces of the package. As the disc 104 spins, the bubble wrap is tensioned and dispensed in a synchronized manner to get wrapped over the package.

[0049] Once the wrapping is completed, as detected by the camera 107, the microcontroller stops rotation of the disc 104 and the roller 112, and simultaneously actuates the motorized blade 113 to cut the bubble wrap and disengage from the roller 112. The motorized blade 113 used herein include a sharp cutting blade, electric motor, rotating shaft, and guide rails. Upon actuation, the motor rotates the shaft connected to the blade 113. The rotating motion drives the blade 113 forward along the guide rails. The moving blade slices through bubble wrap for cutting the wrap.

[0050] A scissor lifting arrangement 114 is provided on the body 101 and a platform 115 is mounted over the lifting arrangement 114, wherein upon wrapping of the package, the microcontroller actuates the four-bar linkage arrangement to grip the package from the chamber 103 and place over the platform 115. Once the package is placed over the platform 115, the microcontroller actuates the scissor lifting arrangement 114 to raise or lower the platform 115 as per the user requirements to position the platform 115 at the user-specified height within the warehouse.

[0051] The scissor lifting arrangement 114 mentioned herein consist of multiple scissor arms which are configured in a crisscross pattern and the ends of the arms are attached to the body 101 and the platform 115 to be lifted. The lifting process is driven by a hydraulic unit consisting of a pump, reservoir, and hydraulic cylinders. On actuation by the microcontroller, the pump forces hydraulic fluid from the reservoir into the cylinders. As the hydraulic fluid enters the cylinders, the pressure increases, causing the pistons inside the cylinders to extend. This extension pushes against the scissor arms, forcing them to spread apart and thus vertically extending the entire scissor arrangement 114. As the arms extend, the platform 115 attached at the top of the scissor arrangement 114 rises smoothly and positioned at the user-specified height within the warehouse.

[0052] The surface of the platform 115 is equipped with a ball caster conveyor belt 116, comprising a matrix of omnidirectional ball casters that facilitate smooth, low-friction movement of packages in any horizontal direction, wherein upon positioning the package at the user-specified height, the microcontroller actuates the ball caster conveyor belt 116 to move the package in the user-specified direction towards wedge-shaped plates 117 installed along three sides of the platform 115.

[0053] The ball caster conveyor belt 116 used herein consist of a matrix of omnidirectional ball casters, motorized actuators, and sensors. Each ball caster consists of a freely rotating ball housed in a socket, for allowing omnidirectional movement of the ball. The microcontroller receives user-specified direction commands and activates the appropriate motorized actuators beneath select ball casters. These actuators slightly tilt or vibrate the casters, for creating directional force to move the package in the user-specified direction towards the wedge-shaped plate.

[0054] Each of these plates 117 are integrated with a conveyor belt along their inner periphery, which are operatively connected to the microcontroller. As the package reaches the plates 117, the microcontroller actuates the respective conveyor belt for gently guiding the package along controlled paths toward specific designated locations such as warehouse shelves, outgoing collection zones, or adjacent transfer arrangement, as specified by the user or determined by the microcontroller from the package codes.

[0055] The conveyor belt used herein consists of a belt stretched across two or more pulleys in close loop and one of the pulley is attached with a driven motor that is interlinked with the microcontroller. On actuation, the driven motor rotates the pulley which as a result rotate the conveyer belt that leads to translate the package placed over the conveyer belt towards the designated locations.

[0056] Further, if the user provides command via the user-interface for transportation of the package to a different location within the warehouse, the microcontroller processes the received command and accordingly actuates the motorized wheels 102 to maneuver the body 101 and transport the package to the specified location. During package transportation, a LIDAR (Light Detection and Ranging) sensor arranged on the body 101, continuously detect the presence of obstacles in proximity to the body 101. This LIDAR sensor emits laser pulses and measures the time taken for the reflections to return, thereby creating a real-time 3D representation of the surrounding environment.

[0057] The microcontroller processes this 3D representation of the surrounding to determine the presence of any static or dynamic obstacle such as a person, another mobile unit, or misplaced items within a predefined safety radius. Upon detection of any such obstacle, the microcontroller immediately triggers a braking means to bring the motorized wheels 102 to a halt, for preventing any potential collision. Simultaneously, the microcontroller initiates a rerouting protocol based on the most recent LIDAR map and stored warehouse navigation data. The revised path is computed using parameters such as shortest distance, obstacle density, and clearance width, ensuring safe maneuverability. Once the new path is confirmed to be free of obstructions, the microcontroller re-actuates the wheels 102 and resumes transportation of the package toward the intended destination.

[0058] Furthermore, during the warehouse package handling, the microcontroller activates a holographic projection unit 119 mounted on the body 101 to project real-time visual updates pertaining to the operational status of the device. The projection includes critical information such as package movements, showing active handling, wrapping, or storage of packages in real-time, obstacle alerts, and device diagnostics including battery level, wheel status, actuator functions, vacuum unit 109 activity, and environmental sensor readings.

[0059] The projection unit 119 operates by using a combination of light sources, mirrors, and lenses to create a three-dimensional visual representation. The projection unit 119 consists of a laser light source that projects onto a beam splitter, which divides the light into multiple paths. These paths are then directed onto a diffraction grating to produce the holographic image. Micro-lenses and mirrors further focus and align the light to form a clear 3D projection. The microcontroller linked with the projection unit 119 controls the image content, ensuring the real-time visual updates are projected, to enhance situational awareness for warehouse personnel by enabling them to visually track device operations from a distance.

[0060] Lastly, a battery is installed within the body 101 which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e. user is able to place as well as moves the device from one place to another as per the requirement.

[0061] The present invention works best in the following manner, where the body 101 as disclosed in the invention is developed to be positioned on the warehouse floor surface and navigate autonomously within the indoor environment via multiple motorized wheels 102 for enabling movement of the body 101 for positioning of the body 101 near the packaging. Upon positioning of the body 101, the four-bar linkage arrangement 106 securely grip packages and position the package within the securing chamber 103. Afterwards, the AI (artificial intelligence) camera 107 integrated with the optical character recognition (OCR) sensor scan and analyze package codes to determine package types and handling requirements. Accordingly, the microcontroller processes the received data and initiates appropriate actions. For fragile packages, the motorized roller 112 rotates the bubble wrap roll to wrap the package and the motorized blade 113 cuts the wrap upon completion. For perishable packages, the L-shaped telescopic link 108 extracts an empty container from the dedicated storage compartment 111 and places the package inside the container. After which the vacuum unit 109 is activated to preserve the contents. The environmental condition monitoring unit continuously assesses temperature, humidity, and air quality, and the microcontroller adjusts vacuum pressure accordingly. After processing, the scissor lifting arrangement 114 raises the platform 115 to transfer the packaged item at the user-specified height. Further, the ball caster conveyor belt 116, guided further by wedge-shaped plates 117 with inner conveyor belts 118 for guiding packages to designated locations. The holographic projection unit 119 displays real-time operational status and the user interface enables remote interaction.
