Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0029] Example 1 like Figures 1-5 As shown, this embodiment discloses a hanging assembly line hanger, which includes a hanger body 2, a return spring 1, an upper lifting device, a self-locking device 3, a self-locking opening device 4 and an unlocking device 5, and also includes a main track, hanger wheels 6, a rotary positioner 7, a hanger rod 8 and a connecting rod 9, a host computer database, a reader and a control device.

[0030] The hanger body 2 includes an upper part 21 and a lower part 22, with the lower part 22 equipped with an adaptive gripper 23. The adaptive gripper 23 is made of an elastic material and can naturally expand and contract according to the thickness of the product, ensuring effective gripping and holding of materials of different thicknesses. A return spring 1 is installed inside the hanger body 2 and is configured to keep the lower part 22 open when not in operation, providing ample space for loading materials.

[0031] The lifting device is installed below the platform surface of the upper platform. The upper cylinder pushes the upper push rod and the top rod to rise from the gap in the platform surface and push the material into the lower part of the main body of the hanger.

[0032] The self-locking device 3 includes a base 31 and a first rotary cylinder 31, a clamping cylinder 32, a push rod 33, and a clamping push block 34 mounted on the base 31. The output shaft of the first rotary cylinder 31 is connected to the base 31 of the self-locking device 3, allowing the entire self-locking device 3 to rotate to a suitable position when needed. The piston rod of the clamping cylinder 32 is connected to the push rod 33, and one end of the push rod 33 is connected to the clamping push block 34. When the adaptive chuck 23 clamps the material coming from the top, the self-locking device 3 rotates to the position of the hanger body 2 under the action of the first rotary cylinder 31 and fixes the hanger body 2. Then, the clamping cylinder 32 pushes the push rod 33 and the clamping push block 34 to compress the upper part 21 of the hanger body 2, and the lower part 22 of the hanger body 2 closes through the lever principle. The adaptive chuck 23 then clamps the material, achieving reliable clamping of the material.

[0033] The self-locking opening device 4 is configured to open the self-locking device 3, causing the lower part 22 of the hanger body 2 to separate and the adaptive clamp 23 to release the material. This device is connected to the self-locking device 3 via a mechanical transmission mechanism, and can release the locking state of the self-locking device 3 when it receives an opening command.

[0034] The unlocking device 5 includes a base and a second rotary cylinder 51, an opening cylinder 52, and an unlocking push block 53 mounted on the base. The output shaft of the second rotary cylinder 51 is connected to the base, enabling the unlocking device 5 to rotate and be positioned. The piston rod of the opening cylinder 52 is connected to the unlocking push block 53. When all product processing steps are completed and the hanger body 2 enters the unloading station, the unlocking device 5 rotates to the position of the hanger body 2 under the action of the second rotary cylinder 51. After the hanger body 2 is fixed, the opening cylinder 52 is activated to move the unlocking push block 53 downwards, pressing down the self-locking opening device 4, opening the self-locking device 3, allowing the hanger to lower the material, and completing the entire unloading process.

[0035] The main track is equipped with a main track chain push rod 33, which provides the running trajectory and driving force for the hanger. The hanger wheel 6 is rotatably engaged on the main track and contacts the main track chain push rod, moving along the track by being pushed by the main track chain push rod. One end of the hanger rod 8 is connected to the hanger wheel 6, and the other end is connected to the rotary positioner 7, serving as support and connection. One end of the connecting rod 9 is hinged to the rotary positioner 7 via a connecting shaft 13, and the other end is hinged to the middle of the hanger body 2, realizing a flexible connection between the hanger body 2 and the running mechanism.

[0036] The communication module is located next to the main track and is used for data communication between the host computer database, the reader, and various control devices.

[0037] In a preferred embodiment, a first cover plate 10 and a second cover plate 11 are also included. The first cover plate 10 is installed at one end of the hanger wheel 6 in the axial direction and connected to the hanger rod 8. The second cover plate 11 is installed at the other end of the hanger wheel 6 in the axial direction. The second cover plate 11 contains an RFID chip for storing and transmitting information about the hanger and the materials it carries, thereby enabling intelligent management and tracking.

[0038] In a preferred embodiment, a label clip 12 is also included, which is installed on the hanger rod 8 and is used to clip product labels. The product labels include, but are not limited to, information such as product model, quality, and size, to facilitate identification and management during the production process.

[0039] In a preferred embodiment, it also includes a clothes hanger pin 24, which slides up and down when the hanger opens and closes, and is integrated with the hanger connecting rod 9. Its function is to fix the lower part of the hanger so that it does not sway from side to side, and to accurately position it when loading and unloading materials.

[0040] The working principle of the entire suspended assembly line is as follows: At the upper station, after the material is placed in place, the self-locking device 3 is activated. The first rotary cylinder 31 rotates the self-locking device 3 to the hanger position and fixes it. The push rod of the upper lifting device pushes the material into the lower part of the hanger body. The clamping cylinder 32 pushes the push rod 33 and the clamping push block 34 to compress the upper part 21 of the hanger body 2. Through the lever principle, the lower part 22 closes, and the adaptive clamp 23 clamps the material. Then the hanger is lifted to the main track and runs along the main track under the push of the main track chain push rod, completing the processing steps through each work station. When it reaches the lower station, the second rotary cylinder 51 of the unlocking device 5 rotates it to the hanger position and fixes it. The opening cylinder 52 pushes the unlocking push block 53 to press down the self-locking opening device 4, releasing the self-locking state. The return spring 1 opens the lower part 22 of the hanger body 2, and the material is smoothly unloaded, completing the entire assembly line operation cycle.

[0041] Example 2 A suspended assembly line hanger system, based on the suspended assembly line hanger described in Embodiment 1, further includes a host computer database, constituting a complete intelligent suspended assembly line hanger system.

[0042] The host computer database, serving as the information management center of the entire system, stores the unique identification of each product and hanger information, and establishes a communication connection with the RFID chip embedded in the second cover plate 11 of the hanger wheel 6. The host computer database can track the location, status, and detailed information of the materials carried by each hanger in real time, including key data such as product model, quality, size, and processing progress. Through bidirectional communication with the RFID chip, the system can achieve precise control and monitoring of the production process.

[0043] In a preferred embodiment, the host computer database is connected to readers located at both the loading and unloading stations. These readers are configured to read product identification and hanger information. At the loading station, the reader reads the RFID chip information during material loading, binds the product identification to the hanger information, and uploads the relevant data to the host computer database. At the unloading station, the reader reads the RFID chip information again during product unloading to confirm the product's processing completion status and updates the product status record in the database.

[0044] The entire system's workflow is as follows: When the crane enters the upper station, the reader automatically reads the crane information from the RFID chip. The host computer database assigns the corresponding product identifier according to the production plan and issues a loading command. The automatic loading and clamping of materials is completed through the top-loading and self-locking device 3. As the crane moves along the main track under the push of the main track chain pusher, the readers at each workstation continuously monitor the crane's status and update the processing progress information to the host computer database in real time. When the crane reaches the lower station, the reader reads the RFID chip information to confirm product processing completion. The host computer database issues an unlocking command, and the unlocking device 5 is activated to complete material unloading. At the same time, update the product completion status.

[0045] Through unified scheduling and management of the host computer database, the system can achieve full traceability of the production process, improve production efficiency and product quality control, ensure that each product can be processed according to the predetermined process flow, and realize the intelligent and automated operation of the hanging production line.

[0046] Example 3 like Figure 6 As shown, this embodiment provides a method for controlling the hangers of a suspended production line. This method is based on the suspended production line hanger system described in Embodiment 2. Through the communication connection between the host computer database and the RFID chip, it realizes automatic control and management of the hangers in the entire production process.

[0047] S1: Write process data into the host computer, set the processing station for each process, and store it in the database. Process data includes product loading data, processing data for each process, and unloading data. Product loading data covers basic product information, loading position, and clamping parameters; processing data for each process includes processing requirements, process parameters, and quality standards for each workstation; unloading data includes product completion status, offline position, and quality inspection results. The host computer organizes and stores this data according to the production plan and product characteristics, following a preset process flow, providing data support for subsequent automated production.

[0048] S2: The host computer configures a unique identifier for each product and generates a physical identifier associated with the product. This physical identifier is then used to bind the hanger information to the database. The host computer generates a unique digital identification code based on the product's model, specifications, batch number, and other information. This code contains all the product's key information. Simultaneously, the system generates a corresponding physical identifier, which can be a barcode, QR code, or other identifiable mark. The host computer associates this physical identifier with the RFID chip information of the specific hanger, establishing a correspondence between the product identifier, physical identifier, and hanger information in the database, ensuring that each product can be accurately tracked and managed.

[0049] S3: When the hanger reaches the online station, the reader reads the physical identifier and hanger information, linking the hanger information to the database. The reader at the online station automatically scans and identifies the product's physical identifier, while simultaneously reading the hanger information stored in the RFID chip within the second cover plate 11 of the hanger wheel 6. The reader transmits the read information to the host computer database in real time. The database system verifies the matching between the product identifier and the hanger information according to the preset binding relationship. Once confirmed, it establishes a real-time data association, providing accurate control commands for subsequent automated operations.

[0050] S4: Under the database command, the hanger descends to the upper station platform, and the material is pushed into the lower part of the hanger. Under the action of the self-locking device 3, the adaptive chuck 23 clamps the material. After the automatic loading of the material is completed, the self-locking device 3 opens the passage, and the hanger is lifted and enters the hanging production line. The host computer database issues a control command to drive the hanger body 2 to descend to the predetermined position. The adaptive chuck 23, made of elastic material, naturally expands and contracts according to the product thickness, and can accurately clamp the material. After the material is pushed into the hanger, the first rotary cylinder 31 in the self-locking device 3 is activated, causing the entire self-locking device 3 to rotate to the fixed position of the hanger body 2. Then the clamping cylinder 32 pushes the push rod 33 and the clamping push block 34 to compress the upper part 21 of the hanger body 2, and the lower part 22 closes through the lever principle. The adaptive chuck 23 firmly grasps and clamps the product. After loading is completed, the self-locking device 3 automatically rotates away, opening the passage for the hanger to move upward. The hanger enters the hanging production line and starts running under the push of the main rail chain push rod 33.

[0051] S5: The hanger carries the product to each processing station to complete the processing steps. The hanger wheels 6 roll on the main track, arriving at each processing station sequentially according to the preset process route in the host computer database. At each workstation, the system executes the corresponding processing operations based on the stored process data, including various processes such as sewing, ironing, and inspection. Throughout the entire operation, the monitoring equipment at each station continuously reads the RFID chip information, updating the product's processing status and progress information to the host computer database in real time, ensuring that each process is completed according to the predetermined requirements.

[0052] S6: When the hanger reaches the lower station, the product is automatically lowered by the unlocking device 5, opening the passage for the empty hanger to be lifted and moved back to the starting station of the hanging production line. The host computer database issues an unlocking command, and the second rotary cylinder 51 in the unlocking device 5 is activated, causing the unlocking device 5 to rotate to the fixed position of the hanger body 2. The opening cylinder 52 pushes the unlocking push block 53 to press down the self-locking opening device 4, prying open the locking mechanism of the self-locking device 3. Under the tension of the return spring 1, the lower part 22 of the hanger body 2 automatically opens, and the product is smoothly unloaded. After unloading, the unlocking device 5 automatically rotates away, opening the passage for the empty hanger to be lifted and moved back to the starting station of the hanging production line, ready for the next round of production.

[0053] The entire control method achieves fully automated management from product launch to product rollout. Through unified scheduling of the host computer database and information tracking using RFID technology, it ensures precise control and efficient operation of the production process, significantly improving production efficiency and product quality consistency.

[0054] The above description is merely a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
