Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile equipment, in particular to a straight twisting machine bobbin lifting mechanism. BACKGROUND

[0002] Under the trend of continuously pursuing high efficiency and high quality production in the textile industry, the coherence and fluency of the entire production process are increasingly critical. As the core equipment of yarn production, the straight twisting machine completes the bobbin production, and the conveying link of the bobbin directly affects the subsequent finished product detection and the entire production cycle. The market demand for yarn continues to rise, which not only requires a substantial increase in output but also sets strict standards for product quality. Therefore, how to efficiently and accurately convey the bobbins produced by the straight twisting machine to the detection process becomes the key to ensuring stable product quality and improving production efficiency.

[0003] Currently, in the straight twisting machine production line, a robot is usually used to realize the transfer of the bobbin. Specifically, the common method includes using a single-arm or multi-arm robot to grab the bobbin and place it on a conveyor belt. In addition, some factories use a clamp driven by a pneumatic or hydraulic system to assist in the handling of the bobbin. Although these methods can basically meet the transmission needs of the bobbin, there are still some shortcomings in actual application. For example, the robot and the clamp are prone to speed mismatching problems when working quickly and continuously, causing the bobbins to accumulate at the outlet of the straight twisting machine, forming a production bottleneck. Even if the speed of the robot catches up with the speed of the straight twisting machine in producing bobbins, the bobbins placed on the conveying table of the next process are prone to tilting due to inertia, and even rolling off the conveying table, which seriously affects the transmission efficiency and the working efficiency of the subsequent detection process.

[0004] However, the existing robot and clamp are prone to speed mismatching problems when working quickly and continuously. When the straight twisting machine produces bobbins quickly, the slow operation of the robot will cause the bobbins to accumulate at the outlet of the straight twisting machine, forming a production bottleneck. Even if the speed of the robot catches up with the speed of the straight twisting machine in producing bobbins, the bobbins placed on the conveying table of the next process are prone to tilting due to inertia, and even rolling off the conveying table, which seriously affects the transmission efficiency and the working efficiency of the subsequent detection process. At the same time, the frequent rotation of the robot can also cause problems such as deviation and inclination of the bobbins when they reach the detection position, increasing the probability of false detection and missed detection, and reducing the reliability of product quality. CONTENT OF THE INVENTION

[0005] In order to improve the stability in the transportation process of the straight twisting machine bobbin, the present application provides a straight twisting machine bobbin lifting mechanism.

[0006] The straight twisting machine bobbin lifting mechanism provided by the present application adopts the following technical scheme:

[0007] The application discloses a straight twister bobbin lifting mechanism, which comprises a hanging conveying track, a plurality of clamping claws are arranged on the conveying track, the clamping claws are equidistantly distributed along the track of the conveying track, the bottom end of each clamping claw is open and the interval of the open bottom end is smaller than the diameter of the bobbin, a discharging conveying table is arranged below the conveying track and corresponds to each straight twister, a liftable supporting table is arranged on the discharging conveying table, the supporting table is used for receiving the bobbin discharged from the discharging port of the straight twister, when the supporting table is lifted to a predetermined height, the rear clamping claw is moved to the two sides of the supporting table through the conveying track, the supporting table is lowered, the bobbin falls into the clamping claw and is moved to the next process together with the clamping claw.

[0008] By adopting the above technical scheme, the bobbin is transported by cooperation of the hanging conveying track and the clamping claw, so that the workshop space can be effectively utilized and the transportation process is prevented from being interfered by other equipment. The open bottom end of the clamping claw is smaller than the diameter of the bobbin, so that when the supporting table is lowered, the bobbin can stably fall into the clamping claw, and the safety and reliability of the transmission are improved. Meanwhile, the liftable supporting table is used for receiving the bobbin to be transferred, the transfer time of the bobbin can be accurately controlled, the bobbin is ensured to be smoothly transferred in the transfer process, and the production bottleneck caused by the speed mismatch is reduced. When the supporting table is lifted to the predetermined height, the rear clamping claw is automatically moved to the two sides of the supporting table, seamless connection is realized, and the working efficiency and the overall smoothness of the production line are further improved.

[0009] Optionally, the clamping claw comprises two oppositely arranged claw arms and a claw head located between the claw arms, the top end of the claw arm is connected to the conveying track, the claw head is connected to the bottom end of the claw arm and is arranged in parallel to the axial direction of the bobbin and abuts against the side wall of the bobbin.

[0010] By adopting the above technical scheme, the structural design of the clamping claw is that the claw arm is fixedly connected to the conveying track and the claw head can abut against the side wall of the bobbin, so that the possibility of shaking or disengaging of the bobbin in the lifting process is effectively reduced. The design not only improves the stability of the bobbin transmission, but also reduces the downtime caused by the falling of the bobbin and improves the production efficiency.

[0011] Optionally, the claw head is provided with an antiskid pad.

[0012] By adopting the above technical scheme, the antiskid pad can effectively enhance the friction force between the claw head and the surface of the bobbin, prevent the bobbin from sliding or rolling in the clamping claw, and thus improve the stability of the bobbin in the conveying process and reduce the transmission error and safety hidden danger caused by the displacement of the bobbin.

[0013] Optionally, a support column is arranged below the conveying track and corresponds to each discharging conveying table, a lifting mechanism for lifting the supporting table is arranged on the sidewall of the support column, the supporting table comprises a supporting box and a supporting tray, the supporting box is connected to the lifting mechanism, and the supporting tray is rotatably arranged on the top of the supporting box and provided with a protective fence on both sides along the conveying direction of the discharging conveying table.

[0014] By adopting the above technical scheme, the rotation design of the supporting tray enables the wire cylinder to be smoothly transferred from the discharging conveying table to the gripper, and the protective fence prevents the wire cylinder from falling or deviating from the predetermined path due to accidental collision or shaking during the transfer process. In addition, the lifting mechanism on the support column ensures the flexibility of the height adjustment of the supporting table, ensuring that the wire cylinder can be accurately delivered into the gripper each time, thereby improving the stability and reliability of the entire system.

[0015] Optionally, a positioning tray is hingedly connected to one side of the supporting tray away from the discharging conveying table, a baffle is arranged on the top wall of the side of the positioning tray close to the hinge shaft, and a supporting rod is arranged on the sidewall of the discharging end of the discharging conveying table, the free end of the positioning tray is lapped on the supporting rod when the supporting table is lowered to the initial position, the wire cylinder is conveyed to the positioning tray through the discharging conveying table, and the end wall of the wire cylinder is supported on the baffle.

[0016] By adopting the above technical scheme, the positioning tray is arranged to enable the wire cylinder to be smoothly transferred from the discharging conveying table to the gripper area, effectively avoiding the instability phenomenon caused by inertia. At the same time, the design of the baffle enhances the stability of the wire cylinder, ensures that the position of the wire cylinder on the positioning tray remains consistent each time, improves the accuracy of the wire cylinder and the gripper, and improves the safety and reliability of the entire transmission process.

[0017] Optionally, a rubber sleeve is sleeved on the supporting rod.

[0018] By adopting the above technical scheme, the rubber sleeve sleeved on the supporting rod can effectively reduce the impact force generated when the free end of the positioning tray contacts the supporting rod during the lowering of the supporting table, reducing the risk of damage or deformation of the positioning tray, thereby prolonging the service life of the equipment and ensuring the stability of the wire cylinder transmission.

[0019] Optionally, a guide slope is arranged at the discharging end of the discharging conveying table, and the guide slope smoothly connects with the receiving position of the positioning tray.

[0020] By adopting the above technical scheme, the guide slope smoothly connects with the receiving position of the positioning tray, which can effectively guide the wire cylinder to be smoothly transferred to the positioning tray, avoid damage or deviation of the wire cylinder due to collision or jam during the transfer process, and improve the stability and accuracy of the wire cylinder transmission.

[0021] Optionally, the discharging conveying table is provided with a fixing column between the supporting table and the lifting mechanism, and a supporting block is arranged on the top of the fixing column and faces one side of the discharging conveying table, and the supporting block is arranged in an inclined manner to the initial angle of the positioning supporting plate matched with the side wall of the bobbin, and is used for supporting the end wall of the bobbin.

[0022] By adopting the above technical scheme, when the bobbin is conveyed from the discharging conveying table to the positioning supporting plate, the end wall of the bobbin will first support on the supporting block arranged in an inclined manner, which helps to guide the bobbin to smoothly transition to the positioning supporting plate, avoiding position deviation caused by collision or inertia. This design not only improves the stability of the bobbin transmission, but also reduces the probability of false detection and missed detection, further improving the reliability of product quality and production efficiency.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The use of suspended conveying tracks and gripper claws to transport bobbins can effectively utilize workshop space and avoid interference from other equipment during the transportation process. The open gap at the bottom end of the gripper claw is smaller than the diameter of the bobbin, so that when the supporting table is lowered, the bobbin can be stably placed in the gripper claw, improving the safety and reliability of the transmission. At the same time, using a lifting supporting table to receive the bobbin to be transferred can accurately control the timing of the bobbin transfer, ensuring smooth transition of the bobbin during the transfer process and reducing production bottlenecks caused by speed mismatch. When the supporting table is raised to a predetermined height, the gripper claws behind it automatically move to both sides of the supporting table, achieving seamless docking and further improving work efficiency and the overall smoothness of the production line.

[0025] 2. The structural design of the gripper claw makes the claw arm fixedly connected with the conveying track, and the claw head can be attached to the side wall of the bobbin, effectively reducing the possibility of bobbin shaking or disengaging during lifting. This design not only improves the stability of the bobbin transmission, but also reduces downtime caused by bobbin falling, improving production efficiency.

[0026] 3. The setting of the anti-skid pad can effectively enhance the friction between the claw head and the surface of the bobbin, preventing the bobbin from sliding or rolling in the gripper claw, thereby improving the stability of the bobbin during conveying, reducing transmission errors and safety hazards caused by bobbin displacement.

In the process of transferring the bobbin 02, the finished bobbin 02 is conveyed from the output end of the straight twisting machine 01 to the discharging conveying table 3, and then moves along the conveying of the discharging conveying table 3 to the supporting table 6, the lifting mechanism 7 drives the supporting table 6 to rise until between the adjacent two clamping jaws 2, the supporting table 6 aligns the bobbin 02 body in the clamping space of the rear clamping jaw 2, when the rear clamping jaw 2 moves to the both sides of the supporting table 6 and is located below the both sides in the axial direction of the bobbin 02, the lifting mechanism 7 drives the supporting table 6 to descend, at this time the bobbin 02 can stably fall into the clamping jaw 2 and be conveyed to the next process together with the clamping jaw 2.

[0036] With reference to Figure 1 , the conveying track 1 is made of high-strength aluminum alloy, has good corrosion resistance and lightweight characteristics, and can withstand long-term high-load operation. In this embodiment, three straight twisting machines 01 are taken as an example.

The guide slope 32 is smoothly connected with the receiving position of the positioning support plate 8. The bobbin 02 is conveyed through the discharge conveying table 3 and smoothly slides along the guide slope 32 to the positioning support plate 8. The bobbin 02 is constrained between the baffle 81 and the protective rail 621.

[0041] With reference to Figure 3In order to prevent the positioning plate 8 from being overturned excessively and causing the device to tip over when the supporting platform 6 is lowered, a fixed column 33 is vertically fixed on the discharging conveying platform 3 and located between the supporting platform 6 and the supporting column 5 and passes through the supporting box 61. A supporting block 331 is fixed on the top of the fixed column 33 and faces the side of the discharging conveying platform 3. The supporting block 331 is inclined to the initial angle of the positioning plate 8 and faces the side wall of the bobbin 02 and is used to support the end wall of the bobbin 02.

The side of the supporting box 61 connected with the linear guide rail 51 is also fixedly connected with the belt 72. The speed reducer 71 can drive the supporting box 61 to be lifted along the linear guide rail 51.

[0045] The implementation principle of the embodiment of the yarn drum lifting mechanism of the direct twisting machine is as follows: in the yarn drum 02 transfer process, the finished yarn drum 02 is conveyed from the output end of the direct twisting machine 01 to the discharging conveying table 3, and is transferred along the conveying of the discharging conveying table 3 to the positioning supporting plate 8; the synchronous wheel 73 is driven to rotate by the speed reducer 71; under the lifting of the linear guide rail 51, the supporting box 61 lifts the positioning supporting plate 8; the stepping motor rotates in the process of lifting the yarn drum 02 by the positioning supporting plate 8, until the drum body of the yarn drum 02 is aligned with the clamping space of the gripper 2; the positioning supporting plate 8 lifts the yarn drum 02 to between the adjacent two grippers 2; the rear gripper 2 moves to the both sides of the positioning supporting plate 8 and is located below the axial direction of the yarn drum 02; the supporting table 6 is driven to descend by the speed reducer 71; at this time, the yarn drum 02 can be stably dropped into the gripper 2 and is conveyed with the gripper 2 to the next process. The efficient and stable transmission of the yarn drum 02 is realized. The special design and anti-skid measures of the gripper 2 greatly reduce the shaking and falling risk of the yarn drum 02 in the transmission process, and improve the reliability and safety of the whole system. The accurate control mechanism of the lifting supporting table 6 ensures the smooth transition of the yarn drum 02 between different stations, and significantly improves the production efficiency and product quality.
