[0002] In the chemical fiber spinning industry, yarn cakes, as semi-finished or finished products, need to be transferred between different production processes (such as winding, doffing, inspection, and packaging). During this process, it is often necessary to transfer and reposition the yarn cakes between production equipment at different heights or workstations.

[0003] Currently, the transfer of silk cakes between production equipment at different heights largely relies on manual operation. This manual turning method is not only labor-intensive and inefficient, but frequent handling and turning can also damage the surface of the silk cakes and even cause the silk threads to fall off, seriously affecting product quality.

[0009] In some embodiments of the first aspect, the flip-mount has a first orientation, and the push rollers are spaced apart along the first orientation.

[0010] In some embodiments of the first aspect, the pusher assembly further includes an ejector disposed on the flip-mount member, the ejector being used to push the yarn cake passing through the pusher axially to disengage the yarn cake from the pusher.

[0011] In some embodiments of the first aspect, the push roller has a hollow channel, and the outer wall of the push roller has a groove that passes through the hollow channel, both the groove and the hollow channel extending along the axial direction of the push roller; The ejector includes a contact portion and a pushing portion.

The contact portion has a connecting end that is movably inserted through the groove and the hollow channel, and the connecting end is connected to the pushing portion. The pushing portion is used to drive the contact portion to move axially along the push roller.

[0012] In some embodiments of the first aspect, the pushing part includes an ejector screw, an ejector slide, and an ejector power unit. The ejector screw and the ejector slide are threadedly connected. Both the ejector screw and the ejector slide are housed within the hollow channel. The axial direction of the ejector screw is parallel to the axial direction of the push roller. The connecting end is connected to the ejector slide.

[0015] The embodiments of this application have the following advantages: This application provides a yarn cake turning table, in which the yarn cake is laterally fed out by the conveying mechanism of the previous process (such as a winding machine or a doffing machine). At this time, at least two push roller assemblies on the turning table are at the same horizontal height, and the push rollers smoothly receive and carry the yarn cake. When the yarn cake needs to change its orientation or be transferred to equipment at a different height, the turning assembly starts to work. The turning mounting component rotates relative to the turning carrier component under the push of the drive mechanism or manual pushing. This action causes all push roller assemblies to rotate as a whole (e.g., rotate 90° or 180°), thereby changing the orientation of the yarn cake from horizontal to vertical, or from a horizontal plane to a plane at another angle. After the turning action is completed, the yarn cake is pushed, and the yarn cake with the adjusted orientation is smoothly transferred to the docking equipment of the next process.

[0016] Therefore, this application significantly reduces labor intensity and improves production efficiency, realizing automated transfer and flipping of the silk cake between different workstations and heights, completely avoiding frequent high-intensity manual handling and flipping operations by operators. The mechanized continuous operation is fast, seamlessly connecting upstream and downstream processes, significantly shortening the silk cake's transit time between processes, thereby greatly improving overall production efficiency. It effectively protects the quality of the silk cake, improves product yield, and avoids localized stress concentration caused by point or line contact. The rolling friction transmission method of the push roller is extremely stable, effectively preventing surface silk thread wear or shedding caused by shaking or sliding during the movement of the silk cake.

[0026] In the chemical fiber spinning industry, yarn cakes, as semi-finished or finished products, need to be transferred between different production processes (such as winding, doffing, inspection, and packaging). During this process, it is frequently necessary to transfer and reposition the yarn cakes between production equipment at different heights or workstations. Currently, the transfer of yarn cakes between production equipment at different heights largely relies on manual operation. This manual turning method is not only labor-intensive and inefficient, but frequent handling and turning can also easily damage the surface of the yarn cakes, even causing yarn shedding, seriously affecting product quality.

[0027] As shown in Figures 1 to 3, to solve the above-mentioned technical problems, this application provides a yarn cake turning table. The yarn cake turning table includes at least two push roller assemblies 200 and a turning assembly. The push roller assemblies 200 include at least two push rollers 200, and the push rollers 200 of each push roller assembly are arranged in parallel. The turning assembly includes a turning support member and a turning mounting member 300. The push rollers 200 of each push roller assembly are all disposed on the turning mounting member 300, and the turning mounting member 300 is rotatably disposed on the turning support member, so that each push roller 200 can switch between at least two working positions.

[0028] In these embodiments, this embodiment provides a yarn cake turning table for automatically lifting, transferring, and adjusting yarn cakes in a chemical fiber spinning production line. The yarn cake turning table mainly includes a push roller 200 assembly and a turning assembly, which work together to complete the spatial posture transformation of the yarn cake.

[0029] In this embodiment, two push roller 200 assemblies are used as an example: a first push roller 200 assembly and a second push roller 200 assembly, arranged side by side to stably thread the yarn through the yarn cake. Of course, in other embodiments, the number of push roller 200 assemblies can be three, four, or five, etc. Each push roller 200 assembly includes one parallel push roller 200, with each push roller 200 evenly spaced along a predetermined direction, and their axes parallel to each other and parallel to the axial direction of the yarn cake. For example, the push roller 200 is made of stainless steel with a smooth surface to reduce frictional damage when in contact with the end face of the yarn cake.

[0030] The flipping assembly includes a flipping support and a flipping mounting component 300. The flipping mounting component 300 is a U-shaped frame structure, with both ends rotatably connected to the flipping support via pivots. The pivots extend horizontally, serving as the rotation center line for the flipping motion.

[0031] Each push roller 200 assembly is fixed on the flip mounting component 300. Therefore, when the flip mounting component 300 rotates around the rotating shaft, all the push rollers 200 it carries and the entire silk cake on them rotate accordingly.

[0032] In this embodiment, the tilting support is a rectangular steel frame structure used for fixed installation on the ground or equipment base, providing overall support. The tilting mounting component 300 is driven by a servo motor and a reducer, allowing precise control of its rotation angle and enabling the switching of the wire cake between two working positions. First working position (horizontal position): The axis of push roller 200 is in a horizontal state, and the yarn cake can be input from the upstream winding machine and enter push roller 200.

[0033] Second working position (vertical position): The flip mounting piece 300 drives the push roller 200 assembly to rotate 90° as a whole, so that the axis of the push roller 200 changes from horizontal to vertical, and the silk cake flips from a horizontal position to a vertical position, which is convenient for subsequent processes to pick up the material.

[0034] Of course, in other implementations, the flipping angle can also be set to a non-right angle such as 60° or 120° to adapt to the connection requirements between different workstations.

[0035] To further enhance automation, this embodiment also includes an angle sensor and a controller (not shown). The angle sensor is located near the rotating shaft and is used to detect the flip angle in real time. The controller receives the sensor signal and controls the start and stop of the servo motor to ensure smooth flipping motion and accurate positioning.

[0036] In some embodiments, the flipping assembly further includes a flipping drive, which is connected to the flipping mounting 300 in a transmission manner. The flipping drive is used to drive the flipping mounting 300 to rotate.

[0037] In this embodiment, the flipping assembly further includes a flipping drive component, which provides a power source for the rotational movement of the flipping mounting component 300. The flipping drive component is a servo motor, fixedly mounted on the flipping support component, and its output shaft is connected to the transmission mechanism via a reducer.

[0038] For example, the transmission mechanism includes a pinion and a large gear. The pinion is connected to the output end of the reducer. The large gear is coaxially fixed to one end of the rotating shaft of the flip-mount component 300. The pinion and the large gear mesh to form a gear transmission pair.

[0039] When the flipping drive is started, the power is amplified by the reducer and then drives the large gear to rotate through the small gear, thereby driving the flipping mounting part 300 to rotate around the rotating shaft, realizing the overall posture flipping of the push roller 200 assembly and the silk cake.

[0040] In other embodiments, the transmission connection may also take one of the following forms: synchronous belt drive or chain drive.

[0041] Optionally, limit switches can be installed at the start and end positions of the flip path as a hardware safety protection. When the flip mounting piece 300 touches the limit switch, the system will forcibly cut off the drive power supply even if the controller does not issue a stop command, to prevent overshoot damage to the equipment.

[0042] In some embodiments, the flipping support includes a base 100 and a leveling part 600. The flipping mounting part 300 is rotatably disposed on the base 100. The base 100 and the leveling part 600 are connected. The leveling part 600 is used to adjust the levelness of the base 100. The axis of the push roller 200 is parallel to the base 100.

[0043] In these embodiments, measures are taken to ensure that the entire flipping table maintains a precise horizontal orientation during installation and operation, thereby ensuring the smoothness and positioning accuracy of the silk cake flipping process.

[0044] The base 100 is a box-shaped steel structure with high rigidity and torsional resistance. The flip-mount component 300 is rotatably mounted in the bearing housing on the base 100 via the rotating shafts at both ends, so that the flipping motion is carried out around the horizontal rotation center line.

[0045] The base 100 has multiple (preferably four) leveling sections 600 located at its four corners. Each leveling section 600 includes a leveling bolt and a support foot. The leveling bolt is vertically positioned and threaded into a threaded hole on the lower surface of the base 100. The support foot is fixed to the bottom of the leveling bolt and is made of wear-resistant rubber or polyurethane material, used to contact the ground and provide anti-slip cushioning.

[0046] The extension length of the leveling bolt can be adjusted by rotating it manually or electrically, thereby fine-tuning the tilt angle of the base 100 in space and ultimately achieving precise calibration of the overall levelness.

[0047] For example, in this embodiment, the upper surface of the base 100 is provided with a level mounting groove, which houses an electronic level sensor for real-time monitoring of the level status of the base 100 and feeding the signal back to the control system. The operator can adjust the leveling bolts according to the prompts.

[0048] Furthermore, the axial direction of the push roller 200 is parallel to the upper surface plane of the base 100. Specifically, when the turning table is in the first working position: the axis of the push roller 200 is horizontal, and the upper surface of the base 100 is also horizontal, with the two having the same spatial direction, ensuring that the silk cake runs smoothly and without deviation during the feeding and discharging process.

[0049] In some embodiments, the at least two working positions include a detection position; the yarn cake turning table further includes a detection component 500, the detection component 500 including a through-beam sensor, the through-beam sensor including a signal transmitting module and a signal receiving module, the signal transmitting module and the signal receiving module being arranged opposite to each other and forming a signal propagation path between them, when each of the push rollers 200 is located in the detection position, the yarn cakes carried on each of the push rollers 200, at least those located at the push-out end of the push roller 200, can block the signal propagation path.

[0050] In these embodiments, the at least two working positions of the flipping table include not only the aforementioned first working position (horizontal position) and second working position (vertical position), but also a detection position. This detection position is an intermediate pause or a specific angle position set by the flipping mounting component 300 during rotation (e.g., when flipped to 30°, 45°, or 60°), used to detect the presence of the yarn cake and ensure that the yarn cake has been completely discharged and detached.

[0051] Of course, for example, the detection position can also be a first working position, which is used to receive the silk cake, and a second working position is used to discharge the silk cake.

[0052] To achieve the above detection function, the signal transmitting module is fixed to one side of the flip-over support. The signal receiving module is fixed to the other side of the flip-over support, facing the signal transmitting module.

[0053] A signal propagation path is formed between the two, which spans the space between the two sets of push roller 200 components, and its height matches the radial profile of the yarn cake (usually slightly lower than the highest point of the outer circle of the yarn cake to ensure reliable detection).

[0054] When each push roller 200 assembly moves to the detection position along with the flip-mounted component 300, if the push roller 200 carries a yarn cake, the main body of the yarn cake (especially the end face or side face of the push roller 200's push-out end) will pass through and block the signal propagation path, causing the signal receiving module to be unable to receive the transmitted signal, thus outputting a material presence signal. If there is no yarn cake present, the signal path is unobstructed, and the receiving module outputs a material absence signal.

[0055] The through-beam sensor uses an infrared light source, has the ability to resist ambient light interference, and has an IP67 protection rating, making it suitable for environments with dust and temperature and humidity changes that may exist in chemical fiber workshops.

[0056] In some embodiments, the flip-mount 300 has a first direction, and the push rollers 200 are spaced apart along the first direction.

[0057] In these embodiments, the flip-mount 300 has a defined spatial extension direction, defined as a first direction. For example, this first direction is perpendicular to the rotation axis of the flip-mount 300.

[0058] Each push roller 200 is spaced apart along the first direction, that is, multiple push rollers 200 are arranged sequentially along the first direction on the flip mounting member 300, maintaining a predetermined distance between each other.

[0059] For example, in this application, three push rollers 200 are equidistantly distributed along a first direction.

[0060] In some embodiments, the pusher roller 200 assembly further includes a pusher 400 disposed on the flip-mount member, the pusher 400 being used to push the yarn cake passing through the pusher roller 200 axially to disengage the yarn cake from the pusher roller 200.

[0061] In these embodiments, the pusher 400 is disposed on the flip-mounted component, located radially outside the pusher roller 200, and opposite to the end of the pusher roller 200. The pusher 400 is used to push the yarn cake axially to completely disengage it from the pusher roller 200, thereby achieving roll release.

[0062] For example, the pusher 400 can be a cylinder-driven push plate, an electric push rod, or a swing-arm type lever. In this embodiment, a miniature cylinder is used as the power source, and its piston rod is connected to a push plate. The push roller 200 pushes out the yarn cake.

[0063] In some embodiments, the push roller 200 has a hollow channel, and the outer wall of the push roller 200 has a groove 210 that passes through the hollow channel. Both the groove 210 and the hollow channel extend along the axial direction of the push roller 200. The pusher 400 includes a contact portion 410 and a pusher portion 420. The contact portion 410 is located on the outside of the push roller 200, and the pusher portion 420 is at least accommodated within the hollow channel. The contact portion 410 has a connecting end that is movably inserted through the groove 210 and the hollow channel, and the connecting end is connected to the pusher portion 420. The pusher portion 420 is used to drive the contact portion 410 to move along the axial direction of the push roller 200.

[0064] In these embodiments, this application provides a highly integrated ejector 400 structure, which uses a built-in drive and external linkage to enable the yarn cake to automatically and smoothly slide off the pusher roller 200 after it leaves the winding head, while avoiding the occupation and interference of external additional mechanisms on the working space.

[0065] The push roller 200 has a hollow structure with an axially extending hollow channel inside. On the outer wall of the push roller 200, an axially extending groove 210 is formed, which communicates with the hollow channel to form a guide path that connects the inside and outside.

[0066] The contact portion 410 is located on the outer side of the push roller 200 and is used to contact the end face of the yarn cake and apply a pushing force during the unrolling stage. For example, the contact portion 410 is a push plate, extending circumferentially along the push roller 200. Alternatively, it can be configured as a contact block.

[0067] The pusher 420 is at least partially housed within the hollow channel of the pusher roller 200, for example, as a push rod or piston structure that can slide axially.

[0068] The contact part 410 has a connecting end that extends from the slide groove 210 into the hollow channel and is fixedly connected to the push part 420.

[0069] Specifically, the connecting end can be a pin or a connecting rod, with an outer diameter slightly smaller than the width of the slide groove 210, so that the contact part 410 can slide axially on the surface of the push roller 200 along the slide groove 210 through the connecting end. When the pushing part 420 moves axially along the hollow channel under power drive (such as pneumatic, hydraulic or motor drive), it drives the contact part 410 to move synchronously along the axial direction of the push roller 200 through the connecting end.

[0070] For example, in this embodiment, the pushing part 420 is driven by a miniature cylinder disposed at the rear end of the push roller 200. The piston rod of the miniature cylinder extends into the hollow channel and is connected to the pushing part 420.

[0071] The length of the slide 210 is set according to the required stroke for the yarn cake to unwind, ensuring that the contact part 410 has sufficient range of motion. Limiting bosses or buffer structures can be provided at both ends of the slide 210 to prevent the connecting end from coming off.

[0072] Clearly, the pusher 420 is internally mounted, occupying no external space, resulting in a clean overall appearance and facilitating operation in narrow spaces between spinning machines. The moving parts are shielded by the pusher roller 200 body, preventing accidental contact by operators or surrounding equipment. The chute 210 and the hollow channel together form a high-precision guiding system, ensuring smooth and unbiased movement of the contact part 410.

[0073] In some embodiments, the pushing unit 420 includes an ejector screw, an ejector slide, and an ejector power unit. The ejector screw and the ejector slide are threadedly connected. Both the ejector screw and the ejector slide are housed within a hollow channel. The axial direction of the ejector screw is parallel to the axial direction of the push roller 200. The connecting end is connected to the ejector slide. The ejector power unit is mounted on the flip-mounted component and is also connected to the ejector screw. The ejector power unit is used to drive the ejector screw to rotate, thereby causing the contact part 410 to move axially.

[0074] In these embodiments, the present application further optimizes the pusher 420 in the pusher 400 by adopting a built-in lead screw and nut transmission mechanism to achieve high-precision, smooth drive and closed-loop control of the roll removal action.

[0075] Specifically, the lead screw and the ejector slide form a threaded transmission connection, with the ejector slide acting as a nut on the lead screw to form a precision lead screw pair. Both the lead screw and the ejector slide are housed within the hollow channel of the push roller 200, and the axial direction of the lead screw is parallel to (preferably coaxial or strictly parallel to) the axial direction of the push roller 200, ensuring that the transmission direction is consistent with the desired motion direction.

[0076] The ejection slide is fixedly connected to the aforementioned connecting end (e.g., by thread or pin). When the ejection slide moves along the axial direction of the ejection screw, it drives the connecting end and its connected contact part 410 to slide synchronously along the axial direction of the push roller 200.

[0077] The ejector power unit is mounted on the flipping mounting component, located outside the rear end of the push roller 200. Its output end extends into the hollow channel via a coupling or flexible drive shaft and is connected to the rear end of the ejector screw to achieve power transmission. In this embodiment, the ejector power unit is selected as a micro servo motor.

[0078] In some embodiments, the lead screw and the inner wall of the hollow channel are rotatably connected.

[0079] In these embodiments, the present application optimizes the rotary support structure of the lead screw to ensure that it can rotate smoothly and reliably in the hollow channel, avoiding transmission jamming or wear caused by radial runout or axial movement.

[0080] The lead screw and the inner wall of the hollow channel of the push roller 200 are rotatably connected. Specifically, at least one bearing seat is provided on the inner wall of the hollow channel, and a rolling bearing or an oil-impregnated bushing (sliding bearing) is installed in the bearing seat. The rod of the lead screw passes through the inner ring of the bearing, so that its outer circumferential surface is rotatably engaged with the inner wall of the hollow channel through the bearing.

[0081] In this embodiment, a set of bearing seats and bearings are provided at the front and rear ends of the hollow channel to form a two-end support structure, so as to improve the rotational stiffness and stability of the lead screw and prevent it from bending or vibrating when rotating at high speed.

[0082] Specifically, the front bearing housing is located near the output end of the push roller 200 and is used to support the front part of the lead screw. The rear bearing housing is located near the tail end of the push roller 200 and is adjacent to the drive shaft of the push-out power unit, and is used to support the rear part of the lead screw and transmit torque.

[0083] The bearings can be selected as deep groove ball bearings or angular contact bearings, which have the advantages of high load-bearing capacity, low frictional resistance, and long service life. The bearing housing can be fixed to the inner wall of the hollow channel by interference fit or threaded connection.

[0084] When the power unit drives the lead screw to rotate, the lead screw rotates around its own axis, while the bearing effectively constrains the radial displacement of the lead screw, allowing it to rotate freely while bearing part of the radial load, ensuring a smooth and stable transmission process.

[0085] In some embodiments, this application also provides a yarn dosing system, which includes a yarn cake turning table as described in any of the above embodiments.

[0086] Since the aforementioned silk cake turning table has the above-mentioned technical effects, the silk feeding system including the silk cake turning table should have the same technical effects, which will not be elaborated here.

[0087] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0088] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0089] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
