Technical Field
[0001] This invention relates to the field of automated textile printing and dyeing equipment technology, specifically to a digital fabric unloading device and method. Background Technology
[0002] In the textile, dyeing, and packaging industries, fabric roll unloading is a core process connecting production, warehousing, and transportation. Its efficiency, accuracy, and safety directly affect the continuity of the entire production line and production cost control. With the rapid development of industrial automation and digitalization technologies, industries such as textiles are gradually transforming towards "less manpower, intelligent, and zero error," which places higher demands on the automation level and digital management capabilities of fabric roll handling. Traditional fabric roll unloading methods and existing related equipment can no longer meet the needs of industry development. In the traditional finished fabric roll shipping process of textile printing and dyeing enterprises, two workers typically manually unpack and transport the crisscrossed stacked fabric rolls one by one onto a conveyor belt. The conveyor belt then transports the fabric rolls to the truck's cargo compartment, where workers receive and place them inside. This process is not only extremely labor-intensive and demanding, but also heavily reliant on manual speed for unloading, resulting in low efficiency. Furthermore, the unloading output cannot be dynamically displayed and still relies on manual statistics, leading to untimely data digitization of unloading quantities and further increasing labor costs. Therefore, we propose a digital fabric roll unloading device and method to address these problems. Summary of the Invention

Start the cylinder to push the rotary motor and rotary drive clamp to extend towards the end face of the fabric roll, so that the rotary drive clamp accurately clamps or presses against the end face of the fabric roll.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] like Figure 1-3 As shown: A digital fabric roll unloading device includes symmetrically distributed device supports 11. An electric rotary divider 14 is installed in the area of the equipment support 11, and a rotating disk 13 is installed at the output end of the electric rotary divider 14 to drive the rotating disk 13 to rotate. The rotating disk 13 carries the cloth roll stacking 10.

A rotary drive assembly is installed on the unloading actuator to drive the cloth roll to rotate and unload. The rotary drive assembly includes a connecting bracket 15 installed on the motion slide rail 3, a cylinder 6 on one side of the connecting bracket 15, a rotary motor 5 installed at the output end of the cylinder 6, and a rotary drive clamp 4 installed at the output end of the rotary motor 5. A buffer ramp base 12 is provided on one side of the equipment support 11 to receive the cloth rolls unloaded from the stack and guide them into the next process. It also includes a digital control device 9, which is electrically connected to the vision recognition mechanism, the unloading execution mechanism, and the rotary drive assembly. It is used to receive recognition information and control the collaborative work of each mechanism, while automatically counting the unloading quantity and uploading the data. The digital control device 9 includes a touch screen device for human-machine interaction, instruction issuance, unloading progress display, and data uploading.
[0017] This invention provides a method for using a digital fabric unloading device, comprising the following steps: S1. The fabric roll stack 10 is moved to the rotating disk 13 in the area of the equipment support 11 by AGV forklift or manually pushed electric forklift. S2. Activate the visual recognition mechanism and use the 3D industrial camera 2 to automatically identify the position information of each independent fabric roll in the three-dimensional space in the fabric roll stacking 10, and transmit the information to the digital control device 9. S3. The operator issues a start command through the touch screen of the digital control device 9, or remotely starts the system through a wireless device; S4. Based on the identified fabric roll position information, the digital control device 9 controls the unloading actuator and the rotary drive assembly to work together: The rotary motor 7 and the rotary drive pulley 8 drive the connecting bracket 15 and its components to move left and right on the motion slide rail 3; The rotary motor 16 and the movable pulley 18 drive the motion slide rail 3 and its components to move up and down on the equipment bracket 11; Make the rotary drive clamps 4 at both ends accurately contact the two end faces of the current top layer roll; S5. Start cylinder 6 to push rotary motor 5 and rotary drive clamp 4 to extend towards the end face of the fabric roll, so that the rotary drive clamp 4 accurately clamps or presses against the end face of the fabric roll. S6. Rotary motor 5 drives rotary drive clamp 4 to rotate the fabric roll, causing it to detach from the fabric roll stack 10 and fall onto the buffer ramp base 12, entering the next process. S7. Following the preset order, unload the top layer of fabric roll one by one until each layer is unloaded; S8. Digital control device 9 controls electric rotary divider 14 to drive rotating disk 13 to rotate 90°, so that the next layer of fabric roll becomes the new top layer. Repeat steps S4 to S7 until all fabric rolls are unloaded or the preset unloading quantity is reached. S9. Throughout the unloading process, the digital control device 9 automatically counts the unloading quantity and uploads the data in real time. It supports progress display and command interaction. The digital control device 9 supports setting the unloading quantity, monitoring the unloading progress in real time, recording the unloading log, and can connect with the upper system for data exchange.
[0018] In this implementation plan: When the digital fabric roll unloading equipment and method are in use, the equipment activates the vision recognition mechanism. The 3D industrial camera 2, mounted on the vision system bracket 1, performs a three-dimensional scan of the fabric roll stack 10 on the rotating disk 13. The vision algorithm automatically identifies the precise position information of each independent fabric roll in the stack in three-dimensional space, including key data such as the end face coordinates, layer distribution, and edge position of the fabric roll. The 3D industrial camera 2 transmits all the identified fabric roll spatial position information to the digital control device 9 in real time and automatically. The digital control device 9 analyzes, processes, and stores the data to provide precise position command basis for the subsequent coordinated actions of each actuator. Operators can interact with the digital control device 9 via its built-in touch screen and directly issue unloading start commands; or they can remotely send start commands to the digital control device 9 via wireless control equipment. After receiving the command, the digital control device 9 issues action preparation commands to the unloading actuator and rotary drive assembly, and the entire equipment enters the working state. The digital control device 9 controls the unloading execution mechanism to complete multi-dimensional movement based on the fabric roll position data transmitted by visual recognition, so as to achieve precise alignment between the rotary drive clamp 4 and the current top layer fabric roll. The rotary motor 2 7 starts, driving the rotary drive pulley 8 at its output end to rotate, driving the connecting bracket 15 and the rotary drive component cylinder 6, rotary motor 1 5, and rotary drive clamp 4 installed on it to move horizontally left and right on the motion slide rail 3, so as to achieve horizontal position calibration. The rotary motor 3 16 at one end of the motion slide rail 3 starts, driving the moving pulley 18 at its output end to rotate on the slide rail of the equipment bracket 11, driving the entire motion slide rail 3 and all components on it to move vertically up and down on the equipment bracket 11, so as to achieve vertical position calibration. Through precise adjustment in two dimensions, the rotary drive clamp 4 at both ends of the equipment is precisely aligned with the two end faces of the current top layer fabric roll, so as to complete the alignment action. After alignment, the digital control device 9 issues an extension command, the cylinder 6 starts and pushes the rotary motor 5 and the rotary drive clamp 4 at its output end to extend linearly towards the end face of the fabric roll until the rotary drive clamp 4 accurately clamps or presses against the two end faces of the fabric roll, ensuring effective connection with the fabric roll during subsequent rotation and unloading, preventing slippage and detachment. After the rotary drive clamp 4 completes clamping / pressing the end face of the fabric roll, the rotary motor 5 starts and drives the rotary drive clamp 4 to rotate the fabric roll at high speed. Using the centrifugal force and mechanical action generated by the rotation, the fabric roll is released from the stacking constraint of the fabric roll stacking 10 and falls smoothly onto the buffer ramp base 12 on one side of the equipment support 11. The buffer ramp base 12 buffers and decelerates the falling fabric roll through the inclined structure, avoiding collision damage to the fabric roll, and guides the fabric roll to slide into subsequent transmission, transfer and other processes, achieving seamless connection between unloading and subsequent processes. After unloading a single roll of fabric from the top layer, the digital control device 9, based on the initially identified position information, controls the unloading actuator and rotary drive assembly to make slight position adjustments. It then repeats the precise alignment, clamping / pressing, and rotating unloading actions on the remaining rolls in the top layer, unloading all rolls in the top layer sequentially according to the preset unloading order until all rolls in the current layer are unloaded. After all rolls in the current layer are unloaded, the digital control device 9 sends a rotation command to the electric rotary divider 14. The electric rotary divider 14 drives the rotating disk 13 to rotate precisely 90°, causing the next layer of rolls in the fabric stack 10 to rotate to the top layer position, becoming a new working layer. Subsequently, the digital control device 9 controls the equipment to repeat all the steps of precise alignment to sequential unloading in the same layer until all rolls are unloaded, or until the unloading quantity preset by the operator is reached, at which point the operation automatically stops. Throughout the entire unloading process, the digital control device 9 collects the equipment's operational data in real time, automatically counts the number of unloaded rolls, and displays the unloading progress in real time via a touch screen; at the same time, it records a complete unloading log, and all data can be uploaded to the upper management system in real time to realize the data-driven and information-based management and control of the unloading operation, and also supports real-time command interaction during the operation. This solution enables unmanned automation and digitalization of the entire process of finished fabric roll delivery at the shipping port of textile printing and dyeing enterprises. It relies on a 3D industrial camera 2 to accurately identify the spatial position of the fabric roll, and a digital control device 9 to coordinate the unloading execution mechanism and the rotary drive component to work together. From the loading of the fabric roll stacking 10 to the unloading of the rotary drive and data statistics, no human intervention is required. The digital control device 9 can also collect and upload unloading data in real time to realize digital management and control of the delivery process, which meets the needs of intelligent transformation in the industry. The equipment significantly improves production efficiency through standardized and automated operations, eliminating the limitations of manual operation speed. Rotary motor 2 (7) and rotary motor 3 (16) drive components to be precisely aligned, rotary motor 1 (5) drives the fabric roll to rotate and unload, and electric rotary divider 14 achieves precise 90° interlayer switching. The coordination of each mechanism has no fatigue period and no speed fluctuation, significantly improving the unloading cycle time. In addition, the buffer ramp base 12 enables seamless connection between unloading and subsequent transfer processes, ensuring the continuity of the production line. The equipment effectively reduces labor and production costs for enterprises. Traditional unloading requires the cooperation of multiple workers, but now only one person needs to issue instructions through the digital control device 9 to complete the operation, which greatly reduces labor costs. At the same time, the precise operation of each component reduces the collision and damage of the fabric roll. The digital control device 9 automatically collects data, saving the input of manual statistics. The stable design of basic components such as the equipment support 11 also reduces the equipment operation and maintenance costs, improving the economic benefits of enterprises from multiple dimensions.
