Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical fiber production and manufacturing, and particularly relates to a yarn pushing trolley steering device. BACKGROUND

[0002] In the process of chemical fiber production, the yarn cakes formed by the winding machine are first transferred to the empty yarn pushing trolley by the yarn cake transfer trolley, and then are loaded onto the hangers of the pushing trolley in sequence. After the pushing trolley is fully loaded, it is transported to the yarn storage room by AGV or manual trolley, so as to realize the transfer of the yarn cakes. The related structure and working principle of the yarn cake transfer trolley and the pushing trolley are disclosed in the utility model patents with publication numbers CN223356635U and CN220785868U respectively.

[0003] In order to improve the transfer efficiency and balance of the yarn cakes, the hangers are usually arranged on both sides of the pushing trolley. Therefore, when the hangers on one side are fully loaded with yarn cakes, the pushing trolley needs to be turned by 180° by means of the ground rotating table, and then the yarn cake transfer trolley continues to load the yarn cakes onto the hangers on the other side, so as to improve the efficiency and positioning accuracy of the yarn loading. Due to the compact space in the production workshop, there are often barriers such as load-bearing walls, which prevent the AGV from normally transporting the pushing trolley to the ground rotating table. Therefore, a chain conveyor is installed on the front side of the rotating table, and a conveying device is installed on the rotating table. The chain conveyor can extend the entrance of the ground rotating table to a position that can be reached by the AGV. When placing the pushing trolley on the ground rotating table, the conveying device is first reset so that its entrance is connected to the outlet of the chain conveyor, and then the AGV places the pushing trolley on the chain conveyor, so that the chain conveyor transfers the pushing trolley to the conveying device. When the pushing trolley is fully loaded with yarn cakes, the conveying device on the rotating table sends the pushing trolley out to the chain conveyor, and finally the AGV transports it to the yarn storage room.

[0004] In order to ensure that the conveying device does not collide with the chain conveyor when the rotating table rotates, a gap is usually reserved between the outlet of the chain conveyor and the entrance of the conveying device. However, in actual use, since the chain conveyor usually uses a support structure composed of chains, chain plates and pallets as a transmission medium, its surface is not absolutely rigid. However, the conveying device usually uses support rollers for transmission, which is a rigid transmission. Therefore, when the pushing trolley transitions from the chain conveyor to the conveying device, its transmission surface suddenly changes from "soft support" to "hard support", and at the same time, the front end of the pushing trolley will slightly sink and be slightly lower than the support surface of the support rollers on the conveying device when entering the above-mentioned gap area, thereby generating longitudinal vibration. This vibration will cause slight deformation of the pushing trolley and the hangers, which will reduce the service life of the pushing trolley over time, and therefore needs to be improved. SUMMARY

[0005] The pusher trolley turning device can reduce vibration of the pusher trolley when the pusher trolley is in transition between the chain conveyor and the conveying device, thereby prolonging the service life of the pusher trolley.

[0006] To solve the above technical problems, the present application is solved by the following technical solutions: The pusher trolley turning device comprises a ground rotating table, a conveying mechanism arranged on one side of the ground rotating table to convey the pusher trolley, a conveying device arranged on the ground rotating table, and a supporting roller arranged on the conveying device to support and receive the pusher trolley. A horizontal interval is maintained between the outlet of the conveying mechanism and the inlet of the conveying device. A lifting roller and a lifting mechanism are arranged in the horizontal interval. The lifting mechanism is provided with a lifting component connected to the lifting roller and is connected to an inflation device through an air path. The inflation device is provided with an exhaust passage. The exhaust passage is connected to a blowing device through an air path. The lifting mechanism is further provided with a reset mechanism for driving the lifting component to retract. When the front end of the pusher trolley is driven by the conveying mechanism to enter the horizontal interval, the inflation device inflates the lifting mechanism to drive the lifting component to lift the lifting roller, so that the lifting roller lifts the part of the pusher trolley located in the horizontal interval. When the front end of the pusher trolley is driven by the conveying mechanism to enter the conveying device and the pusher trolley is supported by at least one supporting roller, the reset mechanism drives the lifting component to retract to exhaust the gas filled in the lifting mechanism. The exhausted gas enters the blowing device through the exhaust passage and is blown to the lifting component by the blowing device to remove dust.

[0007] By arranging the lifting roller and the lifting mechanism in the horizontal interval, when the front end of the pusher trolley enters the interval, the lifting roller can timely lift and lift the pusher trolley, avoiding the front end of the pusher trolley sinking due to the loss of support, thereby eliminating the longitudinal vibration caused by the sudden change of the support surface (i.e. from the “soft support” of the chain conveyor to the “hard support” of the conveying device), protecting the pusher trolley and the hanging structure, and prolonging the service life of the device. By filling gas to lift the lifting component and the lifting roller, an elastic support can be formed at the bottom of the pusher trolley, thereby eliminating the after-shock generated when the pusher trolley is in transition, further protecting the pusher trolley and the hanging structure. The reset mechanism can quickly reset the lifting roller to avoid hindering subsequent transmission, and can accelerate the exhaust of gas in the lifting mechanism during the quick reset process. The exhausted gas forms a high-speed airflow through the blowing device to remove dust from the lifting component, thereby achieving cleaning and maintenance of the lifting component, preventing the lifting roller from being stuck during operation, and further improving the damping effect.

[0008] Preferably, the lifting mechanism is an air spring, and the lifting component is a piston rod arranged vertically in the air spring and connected to the lifting roller.

[0009] Using the above solution, the air spring has excellent buffering and shock absorption performance, which can further absorb impact during the lifting process, making the wire pusher lift more smoothly. At the same time, the connection between the piston rod and the lifting roller is simpler and more reliable, facilitating installation and maintenance.

[0010] Preferably, the inflation device consists of a compressor, an air tank, and a solenoid valve connected in sequence by air passages. The solenoid valve is provided with an air outlet, and the air passage of the air outlet is connected to the lifting mechanism.

[0011] The above-described scheme, which uses a compressor, an air tank, and a solenoid valve to form the inflation device, facilitates system integration and automated control. The air tank provides a stable supply of compressed air, while the solenoid valve enables precise inflation control, ensuring the timeliness and reliability of the lifting operation.

[0012] Preferably, the exhaust passage is located at the solenoid valve and the air path is connected to the exhaust port of the air blowing device.

[0013] By integrating the exhaust channel into the solenoid valve and directly connecting it to the air blowing device, the above solution effectively simplifies the air path structure, reduces pipeline connection points, and lowers the risk of gas leakage. Simultaneously, the solenoid valve can rationally control the opening and closing of the exhaust port according to the application scenario, achieving linkage between exhaust and air blowing. This allows for the efficient utilization of gas discharged from the lifting mechanism for direct dust removal.

[0014] Preferably, the air blowing device includes a receiving groove opened on the ground for accommodating the lifting mechanism and lifting components, an air blowing box disposed on the side wall of the receiving groove, and an air outlet opened on the side wall of the air blowing box and facing the lifting components, wherein the air blowing box is connected to the exhaust port air passage.

[0015] By employing the above-mentioned solution, the lifting mechanism and lifting components are concealed below ground level through a receiving groove, thus avoiding interference with the rotation of the rotary table and the passage of the wire-pushing cart. Positioning the air-blowing box on the side wall of the receiving groove, with its outlet facing the lifting components, allows the discharged gas to be directed onto the surface of the lifting components, effectively removing fiber lint and dust accumulated on the lifting components and lifting mechanism, thereby keeping the mechanism clean and reducing jamming and wear.

[0016] Preferably, a filter screen is provided on the side wall of the receiving trough away from the air blowing box, and a ventilation trough is provided on the side of the filter screen away from the air blowing box, with a ventilation opening extending upward to the ground.

[0017] Using the above solution, a filter and ventilation slot are installed on the other side of the containment tank. This allows the dust-laden airflow generated during air blowing to pass through the filter, intercepting dust and impurities. Clean air is then discharged to the ground through the ventilation slot and vents, thus preventing secondary deposition of dust and impurities within the containment tank. Simultaneously, the vents extend upwards to the ground, enabling natural ventilation, which helps improve exhaust and dust removal efficiency and keeps the containment tank dry.

[0018] Preferably, the outer edge of the filter screen is covered with a rigid edging, the receiving groove extends upward to a receiving opening that connects to the ground for the lifting component to enter and exit, and the two opposite side walls inside the receiving groove are provided with sliding grooves for the two sides of the rigid edging to slide and engage.

[0019] Using the above solution, the filter screen, through the cooperation of rigid edging and sliding grooves, enables a detachable connection, facilitating regular removal for cleaning or replacement, thus reducing maintenance difficulty and costs. Simultaneously, the rigid edging enhances the structural strength of the filter screen, reducing deformation under airflow impact and extending its service life.

[0020] Preferably, the device also includes a receiving groove formed on the ground for accommodating the lifting mechanism and lifting components, a support frame provided between the lifting components and the lifting rollers, a guide sleeve provided on the support frame, and a guide rod provided at the bottom of the receiving groove for the guide sleeve to slide longitudinally.

[0021] By adopting the above solution, connecting the lifting components and lifting rollers with a support frame can improve the installation stability of the lifting rollers, thereby increasing the lifting strength. The sliding fit between the guide sleeve and the guide rod can provide precise guidance for the lifting of the lifting components, preventing the lifting rollers from swaying during lifting or lowering, thus ensuring accurate lifting position.

[0022] Preferably, the reset mechanism includes an electromagnet disposed at the bottom of the guide rod and a ferromagnetic component disposed on the guide sleeve; when the electromagnet is activated, the electromagnet generates a magnetic attraction force on the ferromagnetic component to drive the guide sleeve to descend.

[0023] The above scheme utilizes the magnetic attraction between the electromagnet and the ferromagnetic component as the driving force for the reset mechanism. It has a fast response speed and high control precision, and can quickly pull back the lifting component the moment the front end of the wire pusher is supported by the support roller, thereby improving the working efficiency of the reset mechanism.

[0024] Preferably, the conveying mechanism is a chain conveyor.

[0025] The above solution provides a mature chain conveyor structure with strong load-bearing capacity, suitable for long-distance conveying of heavy-duty wire pushers, and easy to connect with AGVs, effectively solving the problem that AGVs cannot directly deliver to the rotary table due to the compact workshop space.

[0026] Preferably, the conveying device includes two guide rails arranged parallel to each other on the ground rotating platform, and two sets of support rollers are provided and respectively located on the opposite sides of the two guide rails. Each set of support rollers has multiple rollers and is arranged along the length direction of the corresponding guide rail.

[0027] By employing the above scheme, two parallel guide rails and support rollers positioned on opposite surfaces of the two guide rails can provide dual-sided support and guidance for the wire pusher, ensuring uniform force and directional stability during operation on the conveying device. Multiple support rollers arranged along the length of the guide rails provide continuous support points, further reducing vibration and swaying during transmission.

[0028] This invention, by employing the above technical solutions, achieves significant technical effects: By setting lifting rollers and a lifting mechanism within the horizontal interval, when the front end of the wire pusher enters the interval, the lifting rollers can promptly lift and support the wire pusher, preventing its front end from sinking due to loss of support. This eliminates longitudinal vibration caused by abrupt changes in the support surface (i.e., the transition from the "soft support" of the chain conveyor to the "hard support" of the conveying device), protecting the wire pusher and the hanging frame structure and extending the equipment's service life. By filling with gas to lift the lifting components and lifting rollers, elastic support can be formed at the bottom of the wire pusher, eliminating residual vibrations generated during the transition and further protecting the wire pusher and hanging frame structure. The reset mechanism not only allows the lifting rollers to quickly reset to avoid obstructing subsequent transmission but also accelerates the discharge of gas from the lifting mechanism during the rapid reset process. The discharged gas forms a high-speed airflow through a blowing device to remove dust from the lifting components, thus achieving cleaning and maintenance of the lifting components. This makes the lifting rollers less prone to jamming during operation, further improving the shock absorption effect. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 14As shown, this embodiment discloses a wire-pushing cart steering device, including a ground rotary table 1, a conveying mechanism 2 disposed on one side of the ground rotary table 1 for conveying the wire-pushing cart 47, a conveying device 3 disposed on the ground rotary table 1, and support rollers 4 disposed on the conveying device 3 to support and receive the wire-pushing cart 47. The conveying mechanism 2 is a chain conveyor. The specific structure and working principle of the ground rotary table 1 and the chain conveyor are common knowledge in the art and do not involve improvements to this solution, so they will not be described in detail. The conveying device 3 includes two guide rails 31 fixed parallel to the ground rotary table 1. Two sets of support rollers 4 are provided and disposed on opposite sides of the two guide rails 31. Each set of support rollers 4 has multiple rollers arranged along the length of the corresponding guide rail 31. Each support roller 4 includes a hub motor 32 rotatably disposed on the side of the guide rail 31 and a hard tire 33 fixedly sleeved on the outside of the hub motor 32, thereby enabling the conveying device 3 to transport the wire-pushing cart 47. Guide rollers 46 are rotatably mounted on the upper surfaces of both guide rails 31. Multiple guide rollers 46 are arranged along the length of the corresponding guide rail 31. When the wire pusher 47 moves above the guide rail 31, its two sidewalls abut against the outer circumference of the guide rollers 46, thus guiding the wire pusher 47 and preventing it from shifting position during transport on the conveying device 3. A horizontal gap 5 is maintained between the outlet of the conveying mechanism 2 and the inlet of the conveying device 3 to facilitate the rotation of the ground rotary table 1. A lifting roller 6 and a lifting mechanism are installed within the horizontal gap 5. The lifting mechanism has a lifting component connected to the lifting roller 6 and is connected to an inflation device via an air passage. The inflation device has an exhaust channel, and an air blowing device is connected to the exhaust channel via an air passage. The lifting mechanism also has a reset mechanism for driving the lifting component to retract. In this embodiment, when the front end of the pusher 47 travels through the conveying mechanism 2 into the horizontal interval 5, the inflation device inflates the lifting mechanism to cause the lifting component to drive the lifting roller 6 to rise, thereby lifting the part of the pusher 47 located in the horizontal interval 5 by the lifting roller 6, so that the bottom of the front end of the pusher 47 is slightly higher than the upper surface of the supporting roller 4, avoiding strong vibration caused by a hard transition when the pusher 47 is transferred from the conveying mechanism 2 to the conveying device 3, thereby effectively improving the service life of the pusher 47.

[0033] When the front end of the wire pusher 47 passes the horizontal interval 5 and enters the conveying device 3 under the drive of the conveying mechanism 2, and the wire pusher 47 is supported by at least one support roller 4, the reset mechanism drives the lifting component to retract so that the gas filled in the lifting mechanism is discharged. The discharged gas enters the blowing device through the exhaust channel and blows air onto the lifting component through the blowing device to remove dust, thereby reducing the risk of the lifting component being stuck and further improving the shock absorption effect of the lifting mechanism on the wire pusher 47.

[0034] To achieve the lifting and vibration damping functions of the lifting mechanism, a receiving groove 17 is provided within the horizontal interval 5, located on the ground 48. The lifting mechanism is an air spring 7 installed within the receiving groove 17, which is vertically fixed to the bottom of the receiving groove 17 by a bracket 34. The lifting component is a piston rod 11 vertically installed within the air spring 7 and connected to the lifting roller 6. The air spring 7 includes a longitudinally arranged air reservoir 35 and a piston 36 longitudinally sliding within the air reservoir 35. The piston rod 11 extends longitudinally through the air reservoir 35, with its lower end fixed to the piston 36, thus expanding and contracting according to the amount of air in the air reservoir 35.

[0035] To enable the inflation function of the inflation device, the inflation device consists of a compressor 12, an air tank 13, and a solenoid valve 14, all installed on the ground 48 and connected sequentially by air passages. The solenoid valve 14 has an outlet 15 and an inlet 37. Specifically, a one-way valve 38 is installed in the air passage between the compressor 12 and the air tank 13, allowing only one-way gas entry into the air tank 13. This effectively prevents backflow of gas into the air tank 13, which could damage the compressor 12. A pressure gauge 39 is connected to the air tank 13 to monitor the air pressure inside. The gas outlet 40 of the air tank 13 is connected to the inlet 37, and the outlet 15 is connected to the nozzle 41 of the air cylinder 35. The nozzle 41 is located at the bottom of the air cylinder 35 to connect to the space inside the air cylinder 35 below the piston 36.

[0036] To achieve the exhaust function of the exhaust channel, the exhaust channel is integrated into the solenoid valve 14 and the air path is connected to the exhaust port 16 of the air blowing device. The air blowing device includes an air blowing box 18 fixed to the front side wall of the receiving groove 17 and maintaining a certain ventilation distance from the lifting component, and multiple air outlets 19 evenly distributed on the side wall of the air blowing box 18 near the lifting component and facing the lifting component. An air nozzle 42 is integrally provided on the side wall of the air blowing box 18 away from the lifting component, communicating with the inner cavity of the air blowing box 18, and the air nozzle 42 is connected to the exhaust port 16 via the air path.

[0037] The "gas path connection" mentioned in this solution refers to the connection between two or more components through a gas flow path. This path consists of a gas pipe, pipe joint, internal flow channel or valve body channel, which allows gas to flow between components to achieve gas pressure transmission, gas delivery or control functions. This is common knowledge in the field and will not be elaborated here.

[0038] To improve the cleanliness of the accommodating cavity, a stainless steel filter screen 20 is provided on the side wall of the accommodating trough 17 away from the air blowing box 18. A ventilation groove 21 is provided on the side of the filter screen 20 away from the air blowing box 18. The ventilation groove 21 extends upward to a ventilation opening 22 that connects to the ground 48.

[0039] To enable detachable connection of the filter screen 20 and enhance its strength, the outer edge of the filter screen 20 is covered with a rigid edging 23 made of pressed stainless steel sheet. The receiving groove 17 extends upward to a receiving opening 24 that connects to the ground 48 for the lifting component to enter and exit. Two opposite side walls inside the receiving groove 17 are provided with sliding grooves 25 for the two sides of the rigid edging 23 to slide and engage. The sliding grooves 25 extend upward to the receiving opening 24, thus facilitating the installation and removal of the filter screen 20 by personnel.

[0040] To improve the stability of the connection between the lifting roller 6 and the lifting component, a support frame 26 is provided between the lifting component and the lifting roller 6. The upper end of the lifting component is fixed to the midpoint of the support frame 26. Two lifting rollers 6 are provided and installed on both sides of the support frame 26 respectively. The rotation plane of the lifting roller 6 is consistent with the conveying direction of the wire pushing carriage 47, so that it can form two stable and smooth rolling fulcrums at the bottom of the wire pushing carriage 47. Guide sleeves 27 are vertically fixed to the bottom of the support frame 26 and on both sides of the lifting component. Two guide rods 28 are vertically fixed to the bottom of the receiving groove 17 for the longitudinal sliding of the two guide sleeves 27, thereby playing a guiding role and further improving the shock absorption effect and smoothness.

[0041] To achieve the rapid reset function of the reset mechanism, the reset mechanism includes an annular electromagnet 29 fixedly sleeved at the bottom of the guide rod 28 and a ferromagnetic component 30 disposed on the guide sleeve 27. The ferromagnetic component 30 is preferably an annular magnet and is fixedly sleeved on the guide sleeve 27 near the bottom. In this embodiment, when the electromagnet 29 is activated, the electromagnet 29 generates a magnetic attraction force on the ferromagnetic component 30, thereby driving the guide sleeve 27 to descend more rapidly.

[0042] To enable the automatic operation of the wire-pushing carriage 47 transition and lifting mechanism, a proximity switch 43 is installed on the upper surface of the support frame 26, and a proximity switch 44 is installed on the upper surface of the ground rotary table 1 behind the first support roller 4. Proximity switches 43, 44, and pressure gauge 39 are all coupled to a controller 45 and provide corresponding monitoring signals to the controller 45. The controller 45 is preferably a microcontroller. The conveying mechanism 2, hub motor 32, compressor 12, solenoid valve 14, electromagnet 29, and ground rotary table 1 are all coupled to and controlled by the controller 45.

[0043] The specific working principle is as follows: Before the wire pusher 47 enters the conveying mechanism 2 (i.e., the chain conveyor), the ground rotary table 1 is reset by the controller 45 so that the conveying device 3 is connected to the conveying mechanism 2. When the AGV places the fully loaded wire pusher 47 on the conveying mechanism 2, the conveying mechanism 2 can move the wire pusher 47 forward. When the wire pusher 47 enters the area of ​​the horizontal interval 5, the proximity switch 43 on the support frame 26 detects the approach of the front end of the wire pusher 47 and sends a control signal to the controller 45. After receiving the control signal, the controller 45 controls the conveying mechanism 2 to pause and controls the solenoid valve 14 to open the air inlet 37 and the air outlet 15 so that the air tank 13 inflates the air cylinder 35 of the air spring 7, thereby driving the piston rod 11, the support frame 26 and the lifting roller 6 to extend, so that the lifting roller 6 can lift the bottom of the wire pusher 47 to a position slightly higher than the upper surface of the support roller 4 inside the conveying device 3. After slightly raising the wire pusher 47, if the rear half of the wire pusher 47 is still on the conveying mechanism 2, the controller 45 will control the conveying mechanism 2 to continue operating, so as to smoothly transition the wire pusher 47 onto the support roller 4 of the conveying device 3. When the proximity switch 44 on the ground rotary table 1 detects that the front end of the wire pusher 47 is approaching, it indicates that the wire pusher 47 is already above the support roller 4. At this time, the controller 45 controls the solenoid valve 14 to open the exhaust port 16 and close the air inlet 37 to open the exhaust channel. At the same time, the controller 45 activates the electromagnet 29 to magnetically attract the ferromagnetic part 30 on the guide sleeve 27, thereby accelerating the retraction of the piston rod 11. During the retraction of the piston rod 11, it can drive the piston 36 to quickly squeeze out the air in the air storage cylinder 35 and allow the lifting roller 6 on the support frame 26 to quickly descend to the low position, so that the front end of the wire pusher 47 is completely attached to the support roller 4 of the guide rail 31. At this time, the controller 45 controls the conveyor mechanism 2 to operate synchronously with the hub motor 32 so that the wire pusher 47 can fully enter the conveyor mechanism 2.

[0044] After the air in the air reservoir 35 is squeezed out, it enters the air blowing box 18 through the air outlet 15 and exhaust port 16 on the solenoid valve 14 in sequence. Finally, it blows air onto the air spring 7 through the air outlet 19 on the air blowing box 18 to remove dust from the exposed part of the piston rod 11. The airflow generated by dust removal passes through the filter screen 20 and the ventilation slot 21 in sequence, and is finally discharged through the ventilation port 22.

[0045] The filtered dust and impurities will adhere to the filter screen 20. When the filter screen 20 needs to be disassembled and cleaned, simply pull it upwards from the sliding slots 25 on both sides of the receiving groove 17. When installing the filter screen 20, simply use the rigid outer edge 23 of the filter screen 20 to slide it back into the two sliding slots 25.

[0046] After all the gas in the air spring 7 has been expelled, the controller 45 re-controls the solenoid valve 14 to close the air inlet 37, air outlet 15, and exhaust outlet 16. When the pressure gauge 39 detects that the air pressure in the air tank 13 is lower than the lower limit, the controller 45 controls the compressor 12 to run, so as to replenish the air tank 13 with air through the one-way valve 38. When the pressure gauge 39 detects that the air pressure in the air tank 13 has reached the air pressure threshold built into the controller 45, the controller 45 controls the compressor 12 to stop, so as to ensure sufficient air pressure in the air tank 13, thereby improving the operating efficiency of the air spring 7.

[0047] The above-mentioned control part can be implemented by means of the built-in program of the controller 45, which is common knowledge in the field and will not be described in detail here.
