[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0025] In the prior art, the automatic packaging process of silk spindles in the chemical fiber industry has long relied on manual turning operations, resulting in problems such as low efficiency and high error rates. Some automated equipment uses a side-mounted rotation shaft structure, which leads to an overly large rotation radius of the bearing platform, an extended running trajectory, and easy wire shedding of the silk spindles. A certain silk spindle turning machine realizes turning through a side-mounted rotation shaft combined with a lifting mechanism, but the rotation radius is too large.

[0026] To solve the above problems, the applicant of the present invention found that the wire shedding phenomenon of the silk spindles is directly related to the position of the rotation shaft. The side-mounted rotation shaft forces the bearing platform to rotate eccentrically, and the silk spindles are prone to shift under the action of centrifugal force. Placing the rotation shaft on the central axis of the bearing platform or its extension line enables the platform to rotate around the central symmetry axis. This layout effectively reduces the rotation radius and simultaneously reduces the influence of the inertial moment on the silk spindles during operation.

[0027] Therefore, as Figures 1-3 shown, the present invention proposes a technical solution including a frame 1, a lifting assembly 2, a turning drive assembly 3, and a silk spindle bearing platform 4. The lifting assembly 2 and the silk spindle bearing platform 4 are both installed on the frame 1, and the vertical movement of the bearing platform is realized through the lifting assembly 2. The turning drive assembly 3 includes a rotation shaft arranged along the central axis of the bearing platform or its extension line, and drives the bearing platform to complete a 180-degree turning movement.

[0028] The frame 1 is a rigid frame structure that supports the entire device, providing a stable support and installation foundation for the entire turning mechanism. It is usually assembled by welding steel profiles or bolt connection methods, and is used to fix the lifting assembly 2 and the turning drive assembly 3. The lifting assembly 2 is a mechanical device that realizes vertical movement. A hydraulic cylinder, an electric push rod, or a ball screw mechanism can be selected, and the linear lifting of the bearing platform is ensured through guide rails. The turning drive assembly 3 includes a power output unit and a transmission mechanism. For example, a servo motor cooperates with a reducer to drive the rotation shaft to rotate. The silk spindle bearing platform 4 is a work surface for carrying silk spindles, with a positioning structure set on the surface, and a light alloy is selected as the material to ensure the structural strength. The axis of the rotation shaft coincides or is collinear with the center line of the bearing platform, enabling the platform to rotate around its own geometric center, and the rotation radius is reduced to half of the width of the silk spindle bearing platform.

[0029] Specifically, the lifting component 2 first lifts the platform to a predetermined height, and the silk ingots are placed on the bearing platform. When the flipping drive component 3 is activated, the motor transmits the torque force to the flipping shaft through the reducer, and the flipping shaft drives the bearing platform to rotate 180 degrees around the central axis. Since the rotation center coincides with the center of gravity of the platform, the moment of inertia is balanced, and the centrifugal force on the silk ingots is significantly reduced. After the flipping is completed, the lifting component 2 drives the platform to descend to the packaging station, and the silk ingots are transferred to the tray. The rotation trajectory of the whole process is smooth, the movement is compact, and the space requirement for the equipment operation is reduced by about 30%.

[0030] Compared with the prior art, the traditional side-mounted flipping shaft structure causes the platform to rotate eccentrically, and the rotation radius is equal to the platform width plus the shaft offset distance. Through the central axis layout of the present invention, the rotation radius is reduced to the width of the platform itself, and the movement stroke is shortened by about 40%. That is, this structure effectively controls the movement trajectory during the flipping of the silk ingots and eliminates the centrifugal force imbalance caused by eccentric rotation. The bearing platform rotates around the central axis, making the force on the silk ingots uniform and avoiding the scattering and falling off of the silk ingots.

[0031] As a preferred embodiment, as Figures 1-3 shown, the flipping drive component 3 includes a first flipping drive component 31 and a second flipping drive component 32, the silk ingot bearing platform 4 includes a first silk ingot bearing platform 41 and a second silk ingot bearing platform 42, the first flipping drive component 31 is drivingly connected to the first silk ingot bearing platform 41 through a first flipping shaft 313, and the second flipping drive component 32 is drivingly connected to the second silk ingot bearing platform 42 through a second flipping shaft 323.

[0032] The first flipping drive component 31 is a mechanism for independently controlling the flipping of the first silk ingot bearing platform 41. Specifically, it can be realized by using a motor to cooperate with a transmission mechanism to drive the flipping shaft to rotate. By corresponding the drive component with the bearing platform one by one, the rotation radius during single-sided flipping can be reduced. The second flipping drive component 32 is a mechanism for independently controlling the flipping of the second silk ingot bearing platform 42. Specifically, it can be realized by using a drive unit symmetrically arranged with the first flipping drive component 31, so that the two bearing platforms do not interfere with each other during flipping. The first flipping shaft 313 and the second flipping shaft 323 are the rotation central axes of the two bearing platforms, and can be specifically set as rigid shafts coinciding with the extension line of the central axis of the corresponding bearing platform. The inertial offset during rotation can be reduced by driving through the central axis.

[0033] Specifically, the first flipping drive component 31 includes a first drive motor 311, a first transmission mechanism 312, and a first flipping shaft 313. The first drive motor 311 is drivingly connected to the first transmission mechanism 312, the first transmission mechanism 312 is drivingly connected to the first flipping shaft 313, and the first flipping shaft 313 is provided on the extension line of the central axis of the first silk ingot bearing platform 41.

[0034] The first driving motor 311 is the power source for driving the rotation of the flipping shaft. Specifically, a servo motor or a stepper motor can be used to provide precise torque and speed control. The first transmission mechanism 312 is a mechanical device for transmitting the motor power to the flipping shaft. Specifically, a gear set or a synchronous belt pulley mechanism can be used to achieve power transmission and speed reduction adjustment. The first flipping shaft 313 is a rotating shaft that supports the bobbin carrier platform 4 and realizes the flipping action. Specifically, a hollow steel shaft or a cemented carbide shaft can be used. Its axis coincides with or extends along the center line of the bobbin carrier platform 4 to ensure that the flipping center is aligned with the center of gravity of the carrier platform.

[0035] The first driving motor 311 transmits power to the first flipping shaft 313 through the first transmission mechanism 312, driving the first bobbin carrier platform 41 to perform a 180-degree flip around the extension line of its central axis. Since the flipping shaft coincides with the central axis of the carrier platform, the rotation radius of the platform is minimized during the flipping process, and the bobbin only rotates around its own central axis during flipping, avoiding displacement caused by centrifugal force.

[0036] In addition, the first flipping drive assembly 31 further includes a first support shaft 314 and a first driving bearing 315. The first support shaft 314 is arranged on the side of the bobbin carrier platform 4 opposite to the first flipping shaft 313 and is fixedly arranged on the frame 1 through the first driving bearing 315. The first support shaft 314 is an auxiliary support structure arranged on the opposite side of the flipping shaft. Specifically, a high-strength steel shaft body can be used to form a symmetric support with the flipping shaft during the flipping process to prevent the bobbin carrier platform 4 from shifting or shaking due to unilateral force. The first driving bearing 315 is a rotating component for connecting the support shaft and the frame 1. Specifically, a deep groove ball bearing or a tapered roller bearing can be used. Through the structural design of the rolling elements and the cage inside the bearing, the frictional resistance during the rotation of the support shaft is reduced, and at the same time, the axial displacement is restricted.

[0037] More specifically, the second flipping drive assembly 32 includes a second driving motor 321, a second transmission mechanism 322, and a second flipping shaft 323. The second driving motor 321 is drivingly connected to the second transmission mechanism 322, the second transmission mechanism 322 is drivingly connected to the second flipping shaft 323, and the second flipping shaft 323 is arranged on the extension line of the central axis of the second bobbin carrier platform 42.

[0038] The second driving motor 321 is an electric driving device that provides power for the second flipping action. Specifically, a servo motor or a stepper motor can be used to achieve this. By precisely controlling the rotation angle, it ensures the stable flipping of the platform. The second transmission mechanism 322 is a mechanical device that transmits the rotational motion of the driving motor to the flipping shaft. Specifically, a gear set, a synchronous pulley or a chain transmission mechanism can be used to achieve this, which is used to convert the motion form and enhance the torque output. The second flipping shaft 323 is a rigid shaft body that supports and drives the spool carrying platform 4 to rotate. Specifically, a hollow steel shaft or an alloy shaft body can be used. It is arranged on the extension line of the central axis of the carrying platform to match the flipping trajectory of the platform.

[0039] When the second driving motor 321 starts, its output shaft drives the second flipping shaft 323 to rotate through the second transmission mechanism 322. Since the flipping shaft coincides with the extension line of the central axis of the second spool carrying platform 42, the carrying platform rotates 180 degrees around its own geometric center, so that the spool maintains a symmetric motion trajectory during the flipping process. This structure makes the flipping shaft coincide with the rotation center of the carrying platform, and the rotation radius is compressed to half of the width of the platform itself, avoiding inertial deviation caused by eccentric rotation.

[0040] Moreover, it further includes a second support shaft 324 and a second driving bearing 325. The second support shaft 324 is arranged on the side of the spool carrying platform 4 opposite to the second flipping shaft 323, and is fixedly arranged on the frame 1 through the second driving bearing 325. The second support shaft 324 is a rigid shaft body arranged on the other side of the spool carrying platform 4 away from the first flipping shaft 313. Specifically, it can be realized by a alloy steel shaft with a diameter range of 30 - 50 mm, which is used to form a double-point support structure during the flipping process to disperse the gravity load of the carrying platform. The second driving bearing 325 is a rolling bearing installed at the connection between the support shaft and the frame 1. Specifically, a deep groove ball bearing or a spherical roller bearing can be used to achieve smooth rotation of the support shaft during the flipping process by reducing the friction resistance.

[0041] Specifically, when the spool carrying platform 4 performs the flipping action, the first support shaft 314 and the first flipping shaft 313 are respectively located on both sides of the carrying platform to form a symmetric support structure. When the flipping driving assembly 3 drives the flipping shaft to rotate, the support shaft rotates coaxially and in the opposite direction on the frame 1 through the driving bearing, so that the carrying platform completes a 180-degree flip around the axis under the double-point support. The inner ring of the driving bearing is in interference fit with the support shaft, and the outer ring is fixed to the side wall of the frame 1 through a flange structure, and synchronously bears the combined axial and radial loads during the lifting process of the carrying platform.

[0042] The above-mentioned first driving motor 311 and second driving motor 321 are connected to the first spindle bearing platform 41 and the second spindle bearing platform 42 through the first transmission mechanism 312 and the second transmission mechanism 322, and can accurately control the first spindle bearing platform 41 and the second spindle bearing platform 42 to perform multi-angle flipping. Moreover, the first transmission mechanism 312 and the second transmission mechanism 322 have a high-precision transmission ratio, and can realize fine adjustment of the flipping angle; As a preferred implementation manner, the lifting assembly 2 is installed on the frame 1 and is connected to the first spindle bearing platform 41 and the second spindle bearing platform 42. It includes a lead screw nut mechanism and a lifting motor. The lifting motor drives the lead screw nut mechanism to move, ensuring that the first spindle bearing platform 41 and the second spindle bearing platform 42 move up and down smoothly.

[0043] As a preferred implementation manner, as Figure 3 shown, a plurality of clamping assemblies 5 for clamping spindles are provided on the first spindle bearing platform 41 and the second spindle bearing platform 42.

[0044] Specifically, the clamping assembly 5 includes a clamping jaw 51, a clamping jaw cylinder, a pressure-sensitive sensor and a controller. The clamping jaw cylinder is drivingly connected to the clamping jaw 51. The pressure-sensitive sensor is arranged on the clamping jaw 51. The pressure-sensitive sensor is electrically connected to the controller, and the controller is electrically connected to the clamping jaw cylinder.

[0045] The clamping jaw 51 is a mechanical component for directly contacting and clamping the spindle. Specifically, it can be made of a metal alloy into an adjustable-angle V-shaped structure. Its surface is processed with positioning patterns adapted to the inner wall of the spindle paper tube, and is provided with flexible anti-slip patterns, which can effectively prevent the spindle from falling off during flipping and lifting. The clamping jaw cylinder is a pneumatic component that drives the clamping jaw 51 to perform opening and closing actions. Specifically, it can be realized by using a double-acting cylinder and an electromagnetic valve to control the air pressure. The clamping force can be controlled by adjusting the air pressure value. The pressure-sensitive sensor is a detection device for detecting the contact pressure between the clamping jaw 51 and the spindle. Specifically, it can be realized by using a thin-film pressure sensor or a piezoelectric ceramic sensor. It is integrated on the inner surface of the clamping jaw 51 to obtain the clamping pressure data in real time. The controller is an electronic module that processes the sensor signals and controls the cylinder actions. Specifically, it can be realized by using a PLC or an embedded microcontroller. It dynamically adjusts the cylinder output pressure by receiving the feedback signal of the pressure-sensitive sensor.

[0046] Specifically, after the clamping jaw 51 receives the instruction from the controller to open the clamping jaw 51, the corresponding electromagnetic valve is turned on, and the clamping jaw cylinder opens. When the pressure-sensitive sensor reaches the pressure threshold and feeds back the signal to the controller, the controller closes the instruction to open the clamping jaw 51, and the clamping jaw cylinder stops acting with an error of 30 ms. Thus, it is realized that the clamping jaw 51 can automatically adjust the stroke according to the spindle diameter and prevent overpressure damage.

[0047] As a more preferred implementation manner, asFigure 3 As shown, on the surfaces of both the first bobbin carrying platform 41 and the second bobbin carrying platform 42, there are bobbin accommodating grooves 43 that are adapted to the number of clamping assemblies 5. The bobbin accommodating grooves 43 are used to carry bobbins, and the clamping assemblies 5 are placed inside the bobbin accommodating grooves 43.

[0048] The bobbin accommodating grooves 43 are recessed structures formed on the surfaces of the first bobbin carrying platform 41 and the first bobbin carrying platform 41, and their shapes are consistent with the shape of the bobbin. Specifically, after the bobbin is grasped by the robot and placed inside the bobbin accommodating groove 43, the bottom end of the bobbin is embedded in the groove to form a preliminary positioning. At the same time, the clamping assembly 5 is activated, so that the bobbin is fixed by both the support at the bottom of the groove and the lateral clamping force. During the flipping process, the vertical side walls of the bobbin accommodating groove 43 can prevent the lateral sliding of the bobbin due to centrifugal force, while the clamping assembly 5 continuously applies pressure to offset the flipping inertia. For example, when the carrying platform rotates 180 degrees around the central axis, the bobbin maintains a stable posture under the combined action of the groove and the clamping jaws 51, avoiding wire breakage or deviation.

[0049] The present invention also provides an application method for a double flipping mechanism for realizing bobbin turning in a chemical fiber automatic packaging system, which specifically includes the following steps: Wire cart on-line: The wire cart loaded with chemical fiber bobbins is first transported to the wire cart on-line station of the automatic packaging system. According to the positions of the bobbins on the wire cart issued by the total control, the robot accurately identifies the positions of the bobbins on the wire cart, then moves above the bobbins, grabs the bobbins by using the clamping jaws 51, and places them on the bobbin carrying platform 4 of the chemical fiber flipping mechanism, and the bobbins are closely attached to the flexible anti-slip pads.

[0050] Robot places the bobbin on the docking double flipping mechanism: After the robot grabs the bobbin, it places it on the clamping assembly 5 of the flipping mechanism, so that the bobbin falls into the positioning position. After the clamping jaws 51 are opened, at the same time, the fingers of the robot's gripper cylinder are closed, and the bobbin is firmly fixed by the flexible anti-slip clamping jaws 51.

[0051] Flipping operation: The drive motor of the flipping drive device is started, and the bobbin carrying platform 4 is driven to flip through the transmission mechanism. Since the transmission mechanism has high-precision transmission performance, it can accurately flip the bobbin carrying platform 4 by 180 degrees, so that the tail wire of the bobbin is accurately in the downward state. Lifting and placing: The lifting assembly 2 is started, and the lifting motor drives the lead screw nut mechanism to drive the bobbin carrying platform 4 to slowly descend, and the bobbin with the tail wire downward is stably placed in the positioning area of the lower tray. After completing one bobbin placing operation, the robot returns to continue grabbing bobbins, and the chemical fiber flipping mechanism resets and waits for the next bobbin placement. In this way, continuous and efficient packaging of chemical fiber bobbins is realized. In practical applications, first install the double flipping mechanism at the designated position of the automatic packaging system in the chemical fiber industry to ensure that the base is firmly installed. Set parameters such as the cylinder stroke through the control system according to the specifications of the silk ingots produced. When the silk ingot is transported to the working area of the double flipping mechanism, judge whether the silk ingot is in place through the interaction of sensor signals and the detection feedback of the detection switch, and transmit the signal to the controller. The controller immediately outputs an action instruction to control the pneumatic gripper 51 of the flipping mechanism to act and clamp the silk ingot. At the same time, the flipping servo controller starts the driving device, and the motor drives the flipping shaft to rotate at a set speed and torque through synchronous belt transmission and a reducer, and the silk ingot bearing platform 4 rotates accordingly, flipping the silk ingot to a predetermined angle. After the silk ingot is flipped, the lifting assembly 2 starts, driving the silk ingot bearing platform 4 to slowly descend to the specified height. The pneumatic gripper 51 of the flipping mechanism releases the silk ingot under the control of the controller, and places the silk ingot with the tail silk facing down smoothly into the positioning area of the lower tray. Then, the lifting assembly 2 starts again, driving the silk ingot bearing platform 4 to slowly rise to the initial position, thus completing the flipping operation of the silk ingot. The flipped silk ingot is transported to the subsequent packaging process, and at the same time, the control system continues to monitor the transportation of the silk ingot and prepares for the next flipping operation. During the operation of the equipment, the sensor continuously monitors the position of the silk ingot and the operating status of the first silk ingot bearing platform 41 and the second silk ingot bearing platform 42. Once an abnormality occurs, such as the silk ingot being not firmly clamped or the flipping angle deviating, the sensor feeds the data back to the controller. The controller immediately issues an instruction to stop the equipment operation and issue an alarm signal so that the operator can promptly conduct fault troubleshooting and handling.
