Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to a flipping component and a yarn cake flipping table. Background Technology

[0002] In the post-processing of wound products (such as yarn cakes, spools, and cable reels) in industries like chemical fibers and textiles, it is often necessary to flip the workpieces. The stability and reliability of this flipping action are crucial because the workpieces typically have high precision requirements and are prone to surface damage.

[0003] Currently, the main technical solution for workpiece flipping involves using a cylinder or motor-driven swing arm to directly clamp and flip the workpiece. While this mechanism is simple in structure, the flipping process involves significant impact, especially at the start and stop. Because the motion trajectory is a simple circular arc, the acceleration changes drastically, easily leading to relative sliding or collision between the workpiece and the clamp, causing scratches on the workpiece surface, or even causing the workpiece to detach from the clamp. For products like synthetic fiber cakes, which require extremely high surface quality, this solution is insufficient. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a flipping component and a silk cake flipping table that can achieve stable and reliable flipping action.

[0005] This application provides the following technical solution: In a first aspect, embodiments of this application provide a flipping component, the flipping component comprising: A base, the base having a first orientation; The rotating frame and the swing arm are provided. The rotating frame has a first axis and a second axis that are spaced apart. The swing arm has a third axis. The first axis, the second axis and the third axis are arranged parallel to each other and are all perpendicular to the first direction. The first end of the rotating frame is rotatably mounted on one end of the swing arm around the second axis. The other end of the swing arm is rotatably mounted on the base around the third axis. A slide block is slidably disposed on the base along the first direction, and the second end of the flipping frame is rotatably disposed on the slide block about the first axis. When the slide block moves, it drives the flipping frame to flip about the second axis.

[0006] In some embodiments of the first aspect, the flipping assembly further includes a drive member connected to the slide, the drive member being used to drive the slide to move along the first direction.

[0007] In some embodiments of the first aspect, the flipping assembly further includes a position detection element, the position detection element including a position detection sensor having a detection range through which the movement path of the slide passes, and the position detection element being triggered when the slide enters the detection range.

[0008] In some embodiments of the first aspect, the position detection element further includes a position adjustment unit, the position adjustment unit and the position detection sensor, the position adjustment unit being used to adjust the position of the position detection sensor in the first direction.

[0009] In some embodiments of the first aspect, the flipping assembly includes a leveling member, the base and the leveling member are connected, the leveling member is used to adjust the levelness of the base, and the first axis, the second axis, the third axis and the first direction are respectively parallel to the base.

[0010] In some embodiments of the first aspect, the leveling component includes a leveling screw disposed on the base.

[0011] In some embodiments of the first aspect, both the base and the flipping frame are frame structures.

[0012] Secondly, embodiments of this application also provide a silk cake turning table, the silk cake turning table including the turning component as described in any of the above embodiments.

[0013] The embodiments of this application have the following advantages: This application provides a flipping assembly in which a workpiece is fixed on a flipping frame. The flipping frame is connected to a slide and a swing arm via shafts at both ends (a first axis and a second axis), respectively. A power system (not shown in the figure, but could be a cylinder, electric push rod, etc.) drives the slide to move linearly along a first direction (usually horizontal) of the base. The linear motion of the slide, through its first axis connected to the flipping frame, pushes or pulls the second end of the flipping frame. Since the first end of the flipping frame is hinged to the swing arm via the second axis, and the swing arm itself is hinged to the base via a third axis, the movement of the slide forces the flipping frame and the swing arm to produce a composite motion as a whole. This composite motion prevents the flipping frame from performing a simple circular arc motion around a fixed center. Under the uniform linear drive of the slide, the angular velocity change of the flipping frame is smoother, especially at the critical points of start and stop, effectively avoiding sudden stops and starts. When the slide moves to the other end of its stroke, the flipping frame has just completed its flip. This mechanism cleverly transforms the simple linear motion of the drive source into a non-uniform, less impactful flipping motion of the flipping frame, fundamentally improving the motion characteristics.

[0014] Clearly, the flipping process is extremely smooth, effectively protecting the workpiece and greatly reducing the impact during start-up and stopping. Due to the optimized motion trajectory, the angular acceleration changes smoothly, avoiding sudden swings and stops, thus fundamentally eliminating relative sliding or collisions between the workpiece and the fixture caused by inertial forces. This is crucial for workpieces with high surface precision requirements and prone to damage, such as synthetic fiber cakes, effectively preventing surface scratches and fuzzing, and ensuring product quality. The smooth flipping process means that the inertial force acting on the workpiece is small and controllable, greatly reducing the risk of the workpiece loosening or falling from the fixture due to severe vibration or impact, and improving production safety and reliability.

[0024] In related technologies, the post-processing of wound products (such as yarn cakes, spools, and cable reels) in industries like chemical fibers and textiles often requires workpiece flipping. The stability and reliability of this flipping action are crucial because the workpieces typically have high precision requirements and are prone to surface damage. Currently, the main technical solution for workpiece flipping involves using a cylinder or motor-driven swing arm 200 to directly clamp and flip the workpiece. This mechanism is simple in structure, but the flipping process involves significant impact, especially at the start and stop. Due to the simple circular arc motion trajectory, the acceleration changes drastically, easily leading to relative sliding or collision between the workpiece and the clamp, causing scratches on the workpiece surface, or even causing the workpiece to detach from the clamp. For products like chemical fiber yarn cakes, which have extremely high surface quality requirements, this solution is insufficient.

[0025] As shown in Figures 1 and 2, in order to solve the above-mentioned technical problems, this application provides a flipping assembly. The flipping assembly includes a base 400, a flipping frame 100, a swing arm 200, and a slide 600. The base 400 has a first direction; the flipping frame 100 has a first axis and a second axis spaced apart; the swing arm 200 has a third axis. The first axis, the second axis, and the third axis are arranged parallel to each other and are all perpendicular to the first direction. The first end of the flipping frame 100 is rotatably mounted on one end of the swing arm 200 around the second axis, and the other end of the swing arm 200 is rotatably mounted on the base 400 around the third axis. The slide 600 is slidably mounted on the base 400 along the first direction, and the second end of the flipping frame 100 is rotatably mounted on the slide 600 around the first axis. When the slide 600 moves, it drives the flipping frame 100 to flip around the second axis.

[0026] In these embodiments, this embodiment provides a flipping assembly, which is mainly used in the chemical fiber and textile industries to perform a stable and damage-free 180-degree flipping operation on wound products such as yarn cakes and spools. This flipping assembly aims to solve the problems of large impact and easy damage to the workpiece surface caused by the direct driving of the swing arm 200-degree flipping by the cylinder or motor in the prior art.

[0027] The base 400 serves as the mounting foundation for the entire assembly, and its extension direction is defined as a first direction. In this embodiment, the first direction is the horizontal direction.

[0028] The flipping frame 100 is a core component used to support and fix the workpiece to be flipped (e.g., a silk cake). The flipping frame 100 has two parallel and spaced-apart side plates, each with a first axis and a second axis. Both the first and second axes are perpendicular to a first direction of the base 400, i.e., vertical in this embodiment.

[0029] The swing arm 200 also has a third axis, which is perpendicular to the first direction and parallel to both the first and second axes. One end of the swing arm 200 is rotatably connected to the first end of the tilting frame 100 about the second axis via a hinge structure (e.g., a pin and a bearing). The other end of the swing arm 200 is rotatably connected to the base 400 about the third axis via another hinge structure. In this way, the swing arm 200 can act as a lever, swinging on the base 400.

[0030] The slide block 600 is slidably connected along the first direction of the base 400 via a guide rail-slider mechanism (e.g., a linear guide rail pair). The second end of the flip frame 100 is rotatably connected to the slide block 600 about the first axis via a hinge structure.

[0031] In this embodiment, the flipping action is achieved by a drive device (not shown in the figure, such as a cylinder, hydraulic cylinder, or servo motor) that moves the slide 600 along the first direction. Of course, it can also be driven manually.

[0032] In its initial state, the flipping frame 100 is in a horizontal position and is used to place the workpiece to be flipped.

[0033] When a flipping motion is required, the drive unit pushes the slide 600 to move to the left along the first direction. Since the second end of the flipping frame 100 is constrained to the slide 600 and moves accordingly, while the first end of the flipping frame 100 is connected to the base 400 via the swing arm 200, the swing of the swing arm 200 restricts the movement trajectory of the first end. Therefore, the linear motion of the slide 600 is converted into rotational motion of the flipping frame 100 about its second axis through the linkage of the flipping frame 100 and the swing arm 200.

[0034] As the slide 600 continues to move to the left, the tilting frame 100 slowly tilts upward from its horizontal position. Throughout the tilting process, the trajectory of the tilting frame 100 is not a simple circular arc, but a composite curve determined by the linear motion of the slide 600 and the swing of the swing arm 200. This kinematic design makes the changes in the angular velocity and angular acceleration of the tilting frame 100 smoother, effectively avoiding violent impacts during start-up and stopping.

[0035] When the slide 600 moves to its leftmost extreme position, the tilting frame 100 completes its tilt. After the tilt is complete, the drive device reverses its action, causing the slide 600 to return to its rightward reset position, and the tilting frame 100 also returns to its horizontal position, completing one work cycle.

[0036] The flipping assembly provided in this embodiment uses an indirect transmission method, where the linear motion of the slide 600 drives the rotational motion of the flipping frame 100. Utilizing the motion characteristics of the linkage mechanism, this significantly reduces impact and vibration during the flipping process. The flipping action is smooth and controllable, avoiding relative sliding and collision between the workpiece and the fixture, thus effectively protecting the surface quality of workpieces such as wire cakes. Furthermore, the mechanism has a simple structure, mainly composed of a base 400, a flipping frame 100, a swing arm 200, and a slide 600, with few parts, resulting in lower manufacturing and maintenance costs.

[0037] In some embodiments, the flipping assembly further includes a drive member 500 connected to the slide 600, the drive member 500 being used to drive the slide 600 to move along the first direction.

[0038] In these embodiments, the flipping assembly of this embodiment further includes a drive member 500. The drive member 500 is fixedly mounted on the base 400, and its output end (e.g., a piston rod or push rod) is rigidly connected to the slide 600. The drive member 500 is the power source for the entire flipping action, and is used to directly drive the slide 600 to reciprocate linearly along a first direction of the base 400.

[0039] In this embodiment, the drive component 500 is preferably a double-acting cylinder. The cylinder barrel is hinged to the base 400 via a lug, and the piston rod is connected to the slide 600 via a connector. By alternately introducing compressed air into the rod chamber and rodless chamber of the cylinder, the extension and retraction of the piston rod can be precisely controlled, thereby realizing the left and right movement of the slide 600. Using a cylinder as the drive component 500 has the advantages of simple structure, fast response speed, and low cost, making it very suitable for fast and repetitive actions on automated production lines.

[0040] It is understood that the drive component 500 is not limited to a cylinder. In other alternative embodiments, the drive component 500 may also be a hydraulic cylinder, a servo motor with a lead screw and nut mechanism, or a servo motor with a gear and rack mechanism.

[0041] When a flip is required, the control system sends a command to the drive unit 500 (e.g., a cylinder), and the piston rod of the drive unit 500 begins to extend, pushing the slide 600 to move to the left in the first direction.

[0042] In some embodiments, the flipping assembly further includes a position detection element, which includes a position detection sensor having a detection range through which the movement path of the slide 600 passes, and the position detection element is triggered when the slide 600 enters the detection range.

[0043] In order to achieve automated control and status monitoring of the flipping process and ensure the accuracy and safety of the flipping action, the flipping component in this embodiment also includes one or more position detection components.

[0044] The position detection device includes at least one position detection sensor. In this embodiment, two proximity switches are preferably used as position detection sensors, serving as an initial position sensor and an end position sensor, respectively.

[0045] An initial position sensor is mounted on the base 400, and its detection range (i.e., sensing area) covers the stationary position of the slide 600 after reset. When the slide 600 is in the initial position and enters this detection range, the sensor is triggered and sends a signal to the control system indicating that it is ready to flip.

[0046] The endpoint position sensor is also mounted on the base 400, and its detection range covers the extreme position of the slide 600 after it has been fully moved to the left. When the slide 600 is pushed to the leftmost end by the drive component 500 and completes the flip, the sensor on the slide 600 enters the detection range, and is triggered to send a signal to the control system that the slide has been flipped into position.

[0047] The position detection sensor can be of various types, as long as it can detect the position of the slide 600 non-contactly. In addition to the inductive proximity switch mentioned above, photoelectric sensors, magnetic switches, encoders, etc., can also be used.

[0048] In some embodiments, the position detection device further includes a position adjustment unit, a position adjustment unit and a position detection sensor, the position adjustment unit being used to adjust the position of the position detection sensor in a first direction.

[0049] In order to achieve automated control and status monitoring of the flipping process and ensure the accuracy and safety of the flipping action, the flipping component in this embodiment also includes one or more position detection components.

[0050] The position detection component includes at least one position detection sensor (e.g., an initial position sensor and an end position sensor) and a corresponding position adjustment unit.

[0051] The position detection sensor can be a non-contact sensing element such as an inductive proximity switch, photoelectric sensor, or magnetic switch. Its function is to detect whether the slide 600 has moved to a preset key position. The movement path of the slide 600 passes through the detection range of each position detection sensor. When the slide 600 or the sensing plate on it enters the range, the sensor is triggered and sends a signal to the control system.

[0052] Crucially, the position detection component also includes a position adjustment unit. This position adjustment unit is fixedly mounted on the base 400 and connected to the position detection sensor, used to adjust the installation position of the position detection sensor in a first direction.

[0053] In this embodiment, the position adjustment unit is specifically constructed as an elongated mounting groove extending along a first direction, which is formed on the side of the base 400 or on a dedicated bracket. The position detection sensor is fixed by fastening screws passing through the mounting groove. When it is necessary to adjust the detection point of the sensor, simply loosen the fastening screws, slide the sensor along the mounting groove in the first direction to the desired position, and then tighten the fastening screws again to complete the positioning.

[0054] On the one hand, since different specifications of workpieces (such as wire cakes of different diameters) correspond to different flipping endpoint positions, the sensor position can be adjusted to quickly adapt to a variety of products, improving the versatility and flexibility of the equipment. On the other hand, after long-term operation of the equipment, mechanical wear or assembly errors may occur. At this time, the deviation can be compensated by fine-tuning the sensor position without replacing hardware or redesigning the structure, which greatly reduces maintenance costs and downtime.

[0055] It should be emphasized that during the equipment debugging phase or when changing workpiece specifications, the operator can use the position adjustment unit to precisely set the installation coordinates of the initial position sensor and the end position sensor in the first direction according to actual needs, thereby ensuring that the slide 600 triggers the corresponding signal in the correct position and ensuring that the timing logic of the entire flipping cycle is accurate.

[0056] In some embodiments, the flipping assembly includes a leveling component 300, a base 400 and the leveling component 300 are connected, the leveling component 300 is used to adjust the levelness of the base 400, and the first axis, the second axis, the third axis and the first direction are parallel to the base 400 respectively.

[0057] To ensure the accuracy and stability of the flipping action, especially in cases where there are slight unevenness in the ground or different installation sites, the flipping assembly in this embodiment also includes a leveling component 300.

[0058] The leveling component 300 is connected to the bottom of the base 400. Since the kinematic relationship between the tilting frame 100, the swing arm 200, and the slide 600 depends on the strict parallelism between their rotation axes, which are all perpendicular to the first direction, and the overall spatial relationship is based on the base 400, the levelness of the base 400 directly affects the smoothness of the entire mechanism's operation and the tilting accuracy. If the base 400 tilts, it can cause the slide 600 to jam, the swing arm 200 to experience uneven force, and even lead to workpiece displacement or detachment.

[0059] For this purpose, the leveling component 300 is configured to adjust the posture of the base 400 relative to the mounting plane (such as an equipment platform or the ground) to precisely adjust its levelness.

[0060] In this embodiment, the leveling component 300 includes a plurality of (typically three or four) adjustable feet, respectively arranged in the corner areas of the bottom of the base 400. Each adjustable foot includes: A threaded sleeve fixed to the lower surface of the base 400, an adjusting screw threadedly engaged with the threaded sleeve, and a support pad, such as a rubber pad or a metal pad, located at the bottom of the adjusting screw to increase the contact area and prevent slippage.

[0061] Optionally, a locking nut is also provided on the adjusting screw to lock the position after leveling is completed, preventing loosening due to vibration.

[0062] In use, an operator can rotate the adjusting screw rod to move it up and down relative to the threaded sleeve, thereby changing the height of the corresponding fulcrum. When a level meter (such as an electronic level meter or a bubble level ruler) is placed on the upper surface of the base 400 or a specified reference surface, the height of each support leg can be adjusted step by step until the base 400 reaches the required horizontal state.

[0063] In other optional embodiments, the leveling member 300 can also be a wedge gasket combination, a hydraulic or pneumatic automatic leveling system, or an elastic vibration-isolating leveling support.

[0064] In some embodiments, the leveling member 300 includes a leveling screw, and the leveling screw is disposed on the base 400.

[0065] In some embodiments, both the base 400 and the turning frame 100 are of frame structure.

[0066] In these embodiments, both the base 400 and the turning frame 100 adopt a frame structure to balance structural strength, lightweight design, and convenient observation and maintenance of internal mechanisms.

[0067] The base 400 is formed by a plurality of profiles (such as square tubes, rectangular tubes or I-beams) into a rigid support frame via welding, bolt connection or integral forming. The frame is generally arranged in a rectangular or U-shaped layout, the upper surface of the frame forms a reference platform for installing the swing arm 200, the slide seat 600 guide rail and the driving member 500, and the bottom portion is connected with the leveling member 300. The adoption of the frame structure not only significantly reduces the overall weight and the material cost, but also facilitates wiring, installation of sensors, daily cleaning and maintenance. Meanwhile, a reasonable reinforcing plate or reinforcing rib design can effectively improve the torsional rigidity of the base 400 and prevent deformation due to stress during the turning process, thereby ensuring movement accuracy.

[0068] Correspondingly, the turning frame 100 is also configured as a frame structure. Its main body consists of two parallel side plates and a cross beam connected between the two side plates, and the whole is an I-shaped or sun-shaped frame. Bearing seats or hinge holes for installing a first axis and a second axis are respectively provided on the two side plates. A workpiece to be turned (such as a yarn cake) can be placed on the cross beam, or fixed inside the turning frame 100 by an additional clamping mechanism. The frame design enables the turning frame 100 to have good permeability while ensuring sufficient bearing capacity, which is beneficial for workpiece loading and unloading, visual identification (e.g., cooperating with a machine vision system) and dust accumulation prevention.

[0069] In addition, since both the base 400 and the turning frame 100 adopt an open frame structure, the center of gravity distribution of the entire turning assembly is easier to optimize, which helps reduce the load requirement for the driving member 500 and further improves operation stability.

[0070] In some embodiments, this application also provides a silk cake turning table, which includes any of the turning components described in the above embodiments.

[0071] Since the aforementioned flipping component has the aforementioned technical effects, the silk cake flipping table including the flipping component should have the same technical effects, which will not be elaborated here.

[0072] 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.

[0073] 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.

[0074] 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.
