Abstract
Description
Technical Field
[0001] This utility model relates to the field of doffing equipment technology, and in particular to a novel translational doffing mechanism. Background Technology
[0002] In real-world production and daily life, the doffing process is the most tedious process in a spinning mill. It requires a large workforce, heavy equipment, and a large floor space, which is why labor shortages have been so severe in recent years. Currently, it has become a trend for spinning mills to upgrade their spinning machines to intelligent collective doffing devices. However, most collective doffing mechanisms on the market are of the external swing type. Given the tightly packed arrangement of spinning machines in spinning mills, this type of mechanism easily interferes with the operation of adjacent equipment during doffing. Furthermore, external swing doffing mechanisms have disadvantages such as large footprint, bulkiness, inconvenience, and the accumulation of dust and lint during use, requiring frequent maintenance and impacting industrial production efficiency.
[0003] Furthermore, existing automatic doffing mechanisms are, on the one hand, structurally complex and integrated with the entire doffing equipment, making maintenance and replacement difficult; on the other hand, the doffing mechanism is often large in size, requiring a single power unit to supply power. While this can save a significant amount of energy, most existing doffing mechanisms are large and cumbersome, resulting in poor stability due to the long transmission distance during power supply. Moreover, for the increasing number of small manufacturers on the market, such large-volume doffing mechanisms not only increase costs but also affect the overall processing schedule.
[0004] Therefore, existing technologies need further improvement and enhancement. Summary of the Invention
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a novel translational intelligent collective doffing mechanism, which solves the problems of the external swing collective doffing mechanism mentioned in the background technology, such as inconvenience in disassembly and maintenance, low integration, bulkiness and inconvenience, poor stability, and impact on industrial production efficiency.
[0006] To achieve the above objectives, this utility model provides a novel translational doffing mechanism, including a rotary cylinder, a tube gripper, and a support assembly. The support assembly includes a base, a connecting base, a support plate, and a transmission part. The connecting base connects the base and the rotary cylinder. The transmission part includes a rotating shaft, a first transmission component, and a second transmission component. The rotating shaft passes through the base and connects to the rotary cylinder. The two ends of the first transmission component are rotatably connected to the rotating shaft and the second transmission component. The second transmission component is hinged to a U-shaped component at the bottom of the support plate. The transmission part also includes two sets of guide shafts. The guide shafts are perpendicular to the rotating shaft and slidably connected to the base. The first end of the rotating shaft is connected to the side of the support plate away from the rotating shaft.
[0007] In a preferred embodiment of this application, a coupling is installed inside the connecting base, and the two ends of the coupling are respectively connected to a rotary cylinder and a rotating shaft.
[0008] In a preferred embodiment of this application, the first transmission component is a swing arm, which is rotatably connected to the rotating shaft, and a bearing is provided at the connection point.
[0009] In a preferred embodiment of this application, the second transmission component is a shift fork structure, with a U-shaped component and a swing arm respectively hinged at both ends of the shift fork, so as to drive the first and second transmission components to rotate through the rotation shaft, thereby driving the support plate to move horizontally.
[0010] In a preferred embodiment of this application, the guide shaft is a sliding steel shaft, a sliding groove is provided on the side of the base, the sliding steel shaft slides in the sliding groove, a linear bearing is provided in the sliding groove, and a support plate is connected to the side of the sliding steel shaft away from the linear bearing.
[0011] In a preferred embodiment of this application, a connecting plate is provided on the bottom wall of the support plate edge. The connecting plate is connected to the guide shaft. The guide shaft, the U-shaped piece and the transmission part cooperate to realize the conversion of the rotation of the rotating shaft into the translation of the support plate.
[0012] In a preferred embodiment of this application, the pipe gripper includes a pipe gripping body and a holding beam. The holding beam connects the support plate and the pipe gripping body, and a reinforcing plate is provided on the back of the holding beam.
[0013] In a preferred embodiment of this application, the support plate and the U-shaped piece are detachably connected, and the pipe gripping body includes multiple pipe gripping clamps, which are detachably connected to the gripping beam.
[0014] As a preferred embodiment of this application, the pipe gripper includes a left clamp and a right clamp, which can move toward or away from each other, and arc-shaped sliding members are provided in the left clamp and the right clamp.
[0015] In a preferred embodiment of this application, mounting blocks and mating blocks are provided at both ends of the beam, and multiple translational doffing mechanisms are connected through adjacent mounting blocks and mating blocks.
[0016] The beneficial effects of this utility model are as follows: This application, by setting a connecting mechanism between the transmission part and the support plate, and by having the rotating shaft provide power to the rotary cylinder, transforms the rotation of the rotary cylinder into the translational motion of the entire bobbin gripper, thereby realizing the entire doffing operation; furthermore, compared with the traditional large-volume doffing mechanism, this application, by setting a separate cylinder to provide kinetic energy to a separate bobbin gripping structure, and by guiding the translational motion through two sets of guide shafts, has better rigidity, is less prone to deformation during use, is more reliable in use, and operates more smoothly; in addition, this application, by setting the entire structure to be more miniaturized and compact, further reduces the overall volume of the structure, making the structure more compact and better adaptable to confined workshop environments.
[0017] Furthermore, this application adopts a rocker arm and shift fork structure for the transmission part. Compared with the traditional doffing mechanism that directly uses a swing rod or telescopic shaft to achieve the translation of the entire mechanism, the first and second transmission components of this application are integrally formed and connected, which is more compact, reduces the impact of dust and lint, and is more convenient to disassemble and assemble, and easier to maintain.

[0028] like Figures 1 to 3 As shown, this utility model provides a novel translational doffing mechanism, including a rotary cylinder 2, a tube gripper 11, and a support assembly. The support assembly includes a base 1, a connecting base 3, a support plate 9, and a transmission part. The connecting base 3 is used to connect the base 3 and the rotary cylinder 2. The transmission part includes a rotating shaft 13, a first transmission component 6, and a second transmission component 8. The rotating shaft 13 passes through the base 1 and connects to the rotary cylinder 2. The two ends of the first transmission component 6 are rotatably connected to the rotating shaft 13 and the second transmission component 8. The second transmission component 8 is hinged to the U-shaped component 10 at the bottom of the support plate 9. The transmission part also includes two sets of guide shafts 7. The guide shafts 7 are perpendicular to the rotating shaft 13 and are slidably connected to the base 3. The first end of the rotating shaft is connected to the side of the support plate 9 away from the rotating shaft 13.
[0029] Among them, such as Figure 1 and Figure 2As shown, the base 1 has an irregular shape, resembling a U-shaped base structure. One end of the base 1 is connected to the rotary cylinder 2, and the connecting base 3 is connected to the rotary cylinder 2 by bolts. The connecting base 3 has a hollow structure to facilitate the disassembly and assembly of the coupling 4, and then the rotary cylinder 2 drives the rotating shaft 13 to rotate.
[0030] Furthermore, such as Figure 1 As shown, the first transmission component 6 is a swing arm, which is rotatably connected to the rotating shaft 13, and a bearing 5 is provided at the connection. The second transmission component 8 is a shift fork structure, with a U-shaped part 10 and a swing arm respectively hinged at both ends of the shift fork, so that the first transmission component 6 and the second transmission component 8 can be rotated by rotating the rotating shaft 13, thereby driving the support plate 9 to move horizontally.
[0031] Understandably, the shaft of the rotary cylinder 2 is connected to the rotating shaft 13 via the coupling 4. The rotary cylinder 2 drives the rotating shaft 13 to rotate back and forth. A swing arm is provided on the rotating shaft 13, and a keyway is provided on the swing arm to cooperate with the rotating shaft 13. When the rotating shaft rotates, it drives the swing arm to swing synchronously around the center. The force of the swing arm swinging will be further transmitted to the shift fork, which will synchronously transmit the force to the U-shaped part 10. The U-shaped part 10 will further transmit the force to the support plate 9, thereby realizing the transmission of power.
[0032] Furthermore, the guide shaft 7 is a sliding steel shaft, and a sliding groove is provided on the side of the base 1. The sliding steel shaft slides in the sliding groove, and a linear bearing 145 is provided in the sliding groove. The side of the sliding steel shaft away from the linear bearing 145 is connected to the support plate 9.
[0033] The support plate 9 has a connecting plate protruding from its bottom edge. The connecting plate connects to the guide shaft 7. The guide shaft 7, U-shaped piece 10, and transmission part cooperate to convert the rotation of the rotating shaft 13 into the translation of the support plate 9. Furthermore, two sets of guide shafts 7 are provided, and in some cases, multiple sets can be provided. Compared to the traditional doffing structure, this improves the overall load-bearing capacity and rigidity of movement, reduces deformation problems caused by prolonged operation, and enhances the stability of translation during use.
[0034] Furthermore, the U-shaped component 10 further transmits the force to the support plate 9, and the support plate 9 further transmits the force to the sliding steel shaft. When the swing arm swings back and forth, the sliding steel shaft will move back and forth with the swing arm, thereby driving the tube gripper 11 to grasp full yarn and empty yarn tubes. Finally, the rotational force will be converted into the force of the back and forth movement, realizing the parallel sliding grasping action of the yarn tube.
[0035] As a preferred embodiment of this application, such as Figure 1As shown, the pipe gripper 11 includes a pipe gripping body and a holding beam 12. The holding beam 12 connects the support plate 9 and the pipe gripping body, and a reinforcing plate is provided on the back of the holding beam 12. The structure of the reinforcing plate can further improve stability and safety performance during translation, and improve reliability during use. In addition, the support plate 9 is detachably connected to the U-shaped piece 10. The pipe gripping body includes multiple pipe gripping clamps, which are detachably connected to the holding beam 12. The structure of the holding beam 12 can also make it easier to assemble and disassemble the pipe gripper 11, making the entire device more convenient and compact to use.
[0036] In one alternative implementation, such as Figure 3 As shown, the tube gripper includes a left clamping body 18 and a right clamping body 19, which can move towards or away from each other. The left clamping body 18 and the right clamping body 19 are provided with arc-shaped sliding parts 20. The two structures cooperate with each other to enable the tube gripper to hold doffing tubes of different diameters. Taking the left clamping body 18 as an example, if the diameter of the tube gripper is larger, the length of the clamping body can be slightly lengthened by the arc-shaped sliding parts 20. The cooperation of the left and right clamping bodies can adapt to doffing tubes with a certain range of diameters.
[0037] Of course, in order to improve versatility and clamping reliability, the range of application of the tube clamp should not be too large to avoid incompatibility due to the structure of the tube clamp itself. For doffing tubes with larger or smaller diameters, a more suitable tube clamp can be replaced directly by disassembly.
[0038] And, as Figure 1 and Figure 2 As shown, mounting blocks 16 and mating blocks 17 are provided at both ends of the holding beam 12. Multiple translational doffing mechanisms are connected through adjacent mounting blocks 16 and mating blocks 17. The two cooperate with each other to realize the interconnection of multiple holding beams 12. Since the structure of this application itself is mainly focused on centralization and miniaturization, the structure of mounting blocks 16 and mating blocks 17 enables the holding beams 12 to be interconnected, thereby realizing the connection of multiple doffing mechanisms. Through cooperation, a wider range of doffing work can be achieved.
[0039] In addition, to accommodate different connection lengths, the back of the handle 12 is equipped with a slide rail 15 structure, which is fixed to the support plate 9 by bolts. When adjustment is required, the bolts are first removed, then the slide is made, and finally the lock is tightened, which further improves the applicability.
