Technical Field

[0001] This utility model relates to the field of ring spinning textile processing technology, and in particular to an automatic doffing device for ring spinning. Background Technology

[0002] The ring spinning machine has a row of seats for placing yarn bobbins at the bottom. After the yarn is processed, it is wound onto the yarn bobbins below to form a row of spindles. Existing automatic doffing devices are not applicable, thus failing to effectively improve production efficiency. Furthermore, in older roving machines, after spinning, the fully spun yarn was manually removed one by one and empty yarn tubes were inserted, resulting in high labor intensity and extremely low production efficiency. To address these issues, application number 201620449639.2 discloses an automatic doffing device for roving machines. This device includes a main frame, crossbeam, lifting frame, gripping mechanism, lifting mechanism, yarn storage and yarn tube storage, PLC control system, and operation box. By operating the control buttons on the operation box, the PLC control system controls the lifting mechanism, gripping mechanism, and yarn storage and yarn tube storage to work together to clamp the full yarn tubes at the roving machine's spinning position and place them in the yarn storage and yarn tube storage. Then, the empty yarn tubes in the yarn storage and yarn tube storage are clamped and placed back at the roving machine's spinning position. The above-mentioned patent has the following problems when in use: When the above-mentioned device is doffing yarn, it mainly uses a robotic arm to grip the full yarn tube from the outside, and then removes the full yarn tube and replaces it with an empty yarn tube. However, the gripping of the robotic arm has drawbacks. It is not only easy to dirty the yarn, but the full yarn tube will fall off if the gripping force is insufficient. If the gripping is too tight, it will mess up the yarn and affect the quality of the yarn. There is room for improvement.

[0019] This utility model provides an automatic doffing device for ring spinning, referring to... Figures 1-4 An automatic doffing device for ring spinning includes a hollow yarn tube 10 for ring spinning, a support 1, and a control panel 7. A base plate 8 is provided between the support brackets 1. Both the support brackets 1 and the base plate 8 are provided with connecting plates. The connecting plates facilitate the assembly of the support brackets 1 and the base plate 8 with other equipment. Multiple hollow yarn tubes 10 are provided on the base plate 8. A cylinder 2 is installed on the support bracket 1. An installation plate 3 is fixedly installed on one end of the cylinder 2. A diverter pipe 4 is fixedly installed on the base plate of the installation plate 3. Multiple fixing mechanisms 5 are provided on the base plate of the diverter pipe 4. The multiple fixing mechanisms 5 correspond to the multiple hollow yarn tubes 10 respectively. A control panel 7 is provided on one side of the support bracket 1. The cylinder 2 and the multiple fixing mechanisms 5 are all connected to the control panel 7. The fixing mechanism 5 includes an air pipe 51, a solenoid valve 52, and a rubber air bladder 53. The bottom of the diversion pipe 4 is sealed with multiple air pipes 51. Through the coordinated design of the bracket 1, the base plate 8, the control panel 7, the cylinder 2, the air pump 6, the fixing mechanism 5, and the photoelectric sensor 11, the yarn doffing operation is performed by internal support clamping, which solves the problem of external clamping soiling or damaging the yarn, effectively improves the product quality of the yarn, and makes the clamping more secure and practical.

[0020] In this embodiment, multiple air tubes 51 correspond to multiple hollow yarn tubes 10 respectively. Each air tube 51 is equipped with a solenoid valve 52. Each solenoid valve 52 is connected to the control panel 7. The multiple solenoid valves 52 can be independently opened and closed by the preset program in the control panel 7. In this way, the opening and closing of the corresponding solenoid valves 52 can be controlled by analyzing and judging the information transmitted by multiple photoelectric sensors 11.

[0021] In this embodiment, multiple air tubes 51 are each sealed with a rubber airbag 53. The multiple rubber airbags 53 are all smaller than the inner diameter of the multiple hollow yarn tubes 10, which facilitates the insertion of the multiple rubber airbags 53 into the corresponding hollow yarn tubes 10. The multiple rubber airbags 53 are all elastic, which facilitates the deformation of the multiple rubber airbags 53. The outer side of the multiple rubber airbags 53 is provided with an anti-slip layer to increase the friction between the multiple rubber airbags 53 and the multiple hollow yarn tubes 10 and improve the firmness. The anti-slip layer is polyurethane.

[0022] In this embodiment, an air pump 6 is installed on the bracket 1. One end of the air pump 6 is sealed and connected to a hose, and the other end of the hose is sealed and connected to a diverter pipe 4. A guide rod is fixedly installed on the top of the diverter pipe 4. One end of the guide rod is slidably connected to the bracket 1, which serves as a guide and limiter, and is used to deliver gas into multiple rubber airbags 53. The air pump 6 is connected to the control panel 7, and the air pump 6 is regulated by a preset program in the control panel 7. The air pump 6 is equipped with air pressure detection and can be driven in both directions. The model of the air pump 6 is Nanpu Kechuang NP06s.

[0023] In this embodiment, multiple support rods 9 are installed on the base plate 8, and multiple hollow yarn tubes 10 are respectively sleeved on the multiple support rods 9, forming a detachable connection. One end of the multiple support rods is connected to the lower-positioned ring spinning filament covering yarn device. The lower-positioned ring spinning filament covering yarn device includes a device base, a processing panel is fixedly connected to the upper surface of the device base, a fixing seat is fixedly connected to the top of the processing panel, an installation rod is fixedly connected to the top of the fixing seat, a winding drum is sleeved on the outside of the installation rod, and a first tensioning device is movably connected to the upper end of one side of the processing panel. The device consists of a first tensioning wheel, a second tensioning wheel, and a first guide wheel. The combined use of these three wheels increases the yarn tension, preventing yarn slippage. The rotation of the twisting drum, along with the action of the guide coil, causes the outer filament to wind onto the yarn core, thus completing the twisting process and producing covered yarn. The specific structure and working principle of the lower-mounted ring spinning filament covered yarn device can be found in the literature with application number 202020477440.7, which is existing technology and will not be elaborated further.

[0024] In this embodiment, the top of the base plate 8 is provided with multiple mounting slots, and each mounting slot is equipped with a photoelectric sensor 11. Each photoelectric sensor 11 corresponds to a multiple hollow yarn tube 10. Each photoelectric sensor 11 is connected to the control panel 7. The photoelectric sensor detects the change in the diameter of the yarn tube in real time. When the set value is reached, a full tube signal is sent to the control panel 7.

[0025] Working principle: When in use, first connect the power supply and drive the cylinder 2, air pump 6 and multiple solenoid valves 52 through the preset program in the control panel 7. At the same time, it receives information transmitted by multiple photoelectric sensors 11, analyzes and judges it, and sends corresponding control commands to the cylinder 2, air pump 6 and multiple solenoid valves 52. After a certain amount of yarn is wound around multiple hollow yarn tubes 10, the diameter of the multiple hollow yarn tubes 10 increases. As a result, the diameter changes through the action of multiple photoelectric sensors 11 and sends information to the control panel 7. At this time, the control panel 7 analyzes and judges the information through a preset program and sends instructions to the cylinder 2, the air pump 6 and multiple solenoid valves 52. First, one end of each of the multiple rubber airbags 53 is aligned with one end of each of the multiple hollow yarn tubes 10. Then, through the extension drive of the cylinder 2 and the cooperation between the mounting plate 3, the diversion pipe 4, and the multiple air pipes 51, the multiple rubber airbags 53 are inserted into the multiple hollow yarn tubes 10. After that, the air pump 6 is stopped and started. Through the drive of the air pump 6 and the action of the hose, gas is delivered into the diversion pipe 4. At the same time, through the action of the multiple air pipes 51, gas is delivered into the multiple rubber airbags 53 and inflated. This causes the outer sides of the multiple rubber airbags 53 to abut against the inner sides of the multiple hollow yarn tubes 10 and generate sufficient friction. Then, through the reverse drive of the cylinder 2, the multiple rubber airbags 53 drive the multiple hollow yarn tubes 10 to disengage from the multiple support rods 9, thereby achieving the effect of automatic yarn dropping. During this process, since multiple photoelectric sensors 11 correspond to multiple hollow yarn tubes 10 respectively, the control panel 7 receives the information transmitted by the multiple photoelectric sensors 11 and sends an opening command to the corresponding full-tube solenoid valve 52. Thus, through the cooperation between the multiple photoelectric sensors 11 and the multiple solenoid valves 52, the effect of avoiding the removal of hollow yarn tubes 10 that are not full can be achieved.

[0026] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the automatic doffing of the hollow yarn tube 10 be achieved, but also, by using an internal support to clamp the hollow yarn tube 10, the clamping is stable, solving the problems of yarn contamination, soiling, and tangled thread ends caused by external robotic arms. Moreover, the structure is simple and more practical.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
