Description

Technical Field

[0001] The invention belongs to the technical field of ring spinning frames, and particularly relates to a double-cylinder system for the inward and outward swinging of an air frame of an ultra-long spinning frame. Background Art

[0002] In the current field of textile machinery, the ring spinning machine is equipped with an automatic collective doffing system, which involves the inward and outward swinging and up and down movements of the tube grabber, which are completed by the herringbone arm driving the air frame. The short arm of the herringbone arm is usually fitted on the inward and outward swinging arm through a pin shaft, and the inward and outward swinging arm drives the herringbone arm to realize inward and outward swinging; the up and down swinging of the herringbone arm is realized by the long arm of the herringbone arm extending and retracting upward on the spinning machine.

[0003] At present, in the collective doffing system of super-long spinning frames in China, a cylinder is arranged at the rear of the machine to control the inward and outward swing of the air frame of the whole machine. However, with the development of intelligent and special spinning frames, the length of the whole spinning frame is getting longer and longer. If the existing air frame single-cylinder inward and outward swing control structure is still used, the length of the air frame drive shaft from the rear to the head of the machine is long. When the workshop temperature varies greatly at different times, the drive shaft will expand and contract with the change of temperature, and its length will change, especially at the head of the spinning frame. The cumulative change in the length of the drive shaft is greater, causing the connecting rod mechanism on the fixed and transmission tubes for controlling the inward and outward swing of the herringbone arm and the air frame to be displaced, thereby driving the herringbone arm and the air frame to swing outward when the colony system is in the initial state, resulting in a deviation between the inward and outward swing positions of the air frame near the front of the machine and the rear of the machine when the colony system is running, causing the air frame to be misaligned when grabbing and inserting the pipe, resulting in a malfunction in the colony process. Therefore, the maintenance worker needs to stop the machine to adjust and align the air frame, affecting the efficiency and output of the spinning frame. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a double-cylinder system for the inward and outward swing of the air frame of an extra-long spinning frame, improve the original single cylinder into two cylinders, and respectively match the two cylinders with a device system to limit special positions, and then supplement it with the construction of a pneumatic control system, aiming to reduce the impact of temperature on the drive shaft, thereby improving the production efficiency and output of the extra-long spinning frame.

[0036] The double-cylinder system for the inward and outward swing of the air frame of the super-long spinning frame provided by the present invention is applied to the gathering system of the super-long spinning frame, wherein the gathering system described in the present invention is well known to technical personnel in this field, and generally includes a yarn tube conveying mechanism, an air frame lifting mechanism, an air frame inward and outward swing mechanism, a yarn tube grabbing mechanism and a yarn guide plate flipping mechanism, and the control system is combined with various sensors to carry out collaborative production of various mechanisms, and finally obtain the finished spinning product. In view of the operating conditions of the super-long spinning frame, the present invention aims at the problem that the inward and outward swinging action of the air frame of the super-long spinning frame is greatly affected by the temperature changes in the workshop. A double-cylinder system applied to the super-long spinning frame is proposed in view of the working conditions of the super-long spinning frame, aiming at the problem that the inward and outward swinging action of the air frame of the super-long spinning frame is greatly affected by the temperature changes in the workshop, and strives to solve the misalignment fault caused by the inward and outward swinging action of the air frame.

[0037] The solution provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0038] In this technical solution, if Figure 1-5 As shown, a double-cylinder system for the inward and outward swing of the extra-long spinning frame air frame is used in the gathering system of the extra-long spinning frame. The gathering system is symmetrically arranged on both sides of the spinning frame body 1 to form two symmetrical gathering stations, wherein the spinning frame body 1 includes a plurality of middle wall panels 101 for supporting the entire extra-long spinning frame; each gathering station includes an air frame 2, and the bottom of the air frame 2 is connected to a transmission tube 3 through a herringbone arm assembly.

[0039] The two air frames 2 are driven by a double-cylinder system for their inward and outward swinging movements relative to the spinning frame body 1 with the transmission tube 3 as the axis. The inward and outward swinging movements described in the present invention refer to: the air frame 2 is driven by power to move closer to and away from the spinning frame body 1 with the transmission tube 3 as the axis, wherein the movement closer to the spinning frame body 1 is the inward swing; the movement away from the spinning frame body 1 is the outward swing.

[0040] Generally speaking, the dual-cylinder system includes: a mid-vehicle cylinder system 4, a rear-vehicle cylinder system 5, a limit system 6 and a pneumatic control system 7.

[0041] Among them, such as Figure 2-3 As shown, the cylinder system 4 in the vehicle includes a cylinder box 401, which is arranged on the spinning frame body 1 and is also located on one side of the middle wall panel 101 in the middle of the spinning frame body 1. The cylinder box 401 is surrounded by six sides of the mounting plate, and anchor bolts are provided at the four corners of the bottom.

[0042] A first cylinder 403 is provided in the cylinder box 401, and the bottom of the cylinder body of the first cylinder 403 is hinged to the inside of the cylinder box 401 through a first mounting seat 404, so that the first cylinder 403 has a structural basis for flipping and fine-tuning from the front part of the spinning frame body 1 to the rear part of the vehicle; in addition, the output end of the first cylinder 403 is connected to the first transmission shaft 9 through the cylinder joint 8, and the first transmission shaft 9 passes through the side wall of the cylinder box 401 and extends to the front part of the spinning frame body 1, and finally acts on the range between the middle part and the front part of the spinning frame body 1. In this range, several groups of inward and outward swing components 10 with the same structure are provided on the first transmission shaft 9, and the inward and outward swing action of the air frame 2 in the range between the middle part and the front part of the spinning frame body 1 is realized through the inward and outward swing components 10.

[0043] Furthermore, if Figure 4-5 As shown, the rear end cylinder system 5 includes a rear end base plate 501, which is arranged at the rear end of the spinning frame body 1. A second cylinder 502 is provided on the rear end base plate 501. The bottom of the cylinder body of the second cylinder 502 is hinged to the rear end base plate 501 through a second mounting seat 503, so that the second cylinder 502 also has a structural basis for flipping and fine-tuning from the front end of the spinning frame body 1 to the rear end.

[0044] The output end of the second cylinder 502 is connected to the second transmission shaft 11 through the cylinder joint 8. The second transmission shaft 11 extends to the middle part of the spinning frame body 1, and finally acts on the range between the rear part and the middle part of the spinning frame body 1. In this range, several groups of inward and outward swing components 10 with the same structure are also provided on the second transmission shaft 11, and the inward and outward swing action of the air frame 2 in the range between the rear part and the middle part of the spinning frame body 1 is realized through the inward and outward swing components 10.

[0045] As an innovation of the present invention, the setting of the cylinder system 4 in the middle of the car and the cylinder system 5 at the rear of the car abandons the single cylinder in the original super-long spinning frame, and adopts two cylinders to drive the transmission shaft in sections, that is: the first cylinder 403 and the second cylinder 502 are used to divide the transmission shaft into a first transmission shaft 9 and a second transmission shaft 11, and drive them respectively, which directly reduces the influence of temperature on each section of the transmission shaft, and avoids the misalignment failure of the air frame grabbing and inserting actions during the operation of the spinning frame colony system, thereby ensuring the working efficiency and output of the spinning frame.

[0046] It should be noted that, in the present invention, the first cylinder 403 is exactly the same as the second cylinder 502; and the cylinder joint 8 includes a first connecting part 801, a limiting part 802 and a second connecting part 803 that are integrally connected, wherein the first connecting part 801 and the second connecting part 803 are respectively located on both sides of the limiting part 802, and a connecting groove is provided on the first connecting part 801, and a first rotating pin 804 is provided on both sides of the connecting groove through the body of the first connecting part 801.

[0047] Based on the above embodiment, when the cylinder joint 8 is applied to the cylinder system 4 in the vehicle, as shown in FIG. Figure 2 As shown, the cylinder joint 8 cooperates with the end of the first transmission shaft 9 through the first connecting part 801, thereby realizing the structural basis for the first transmission shaft 9 to rotate in the connecting groove with the first rotating pin 804 as the axis; the cylinder joint 8 is connected to the output end of the first cylinder 403 through the second connecting part 803.

[0048] When the cylinder joint 8 is used in the rear cylinder system 5, as shown in FIG. Figure 4 As shown, the cylinder joint 8 cooperates with the end of the second transmission shaft 11 through the first connecting part 801, thereby realizing the structural basis for the second transmission shaft 11 to rotate in the connecting groove with the first rotating pin 804 as the axis; the cylinder joint 8 is connected to the output end of the second cylinder 502 through the second connecting part 803.

[0049] At this point, a power component for the inward and outward swinging movement of the air frame 2 with the first cylinder 403 and the second cylinder 502 as the core is obtained. Specifically, in each cylinder system, the cylinder system 4 in the middle of the vehicle and the cylinder system 5 at the rear of the vehicle both need to be equipped with the inward and outward swing component 10 to realize the inward and outward swinging movement of the air frame 2.

[0050] The inside-outside swing assembly 10 includes a swing arm seat 1001 , an L-shaped swing arm member 1004 , and a swing bearing seat 1011 .

[0051] Among them, such as Figure 3-6 As shown, the swing arm seat 1001 is arranged on the middle wall plate 101, and a group of swing arm ears 1002 are provided at the bottom end of the swing arm seat 1001, and a second rotating pin 1003 is connected between the group of swing arm ears 1002.

[0052] The L-shaped swing arm member 1004 includes a rotating sleeve 1005, which is rotatably sleeved on the outer surface of the second rotating pin 1003 between a set of swing arm ears 1002. A set of front swing arms 1006 and a set of rear swing arms 1007 are provided on the outer wall of the rotating sleeve 1005 along different directions. The front swing arms 1006 and the rear swing arms 1007 are perpendicular to each other. A rib plate 1008 is provided between the front swing arms 1006, and the ends of the front swing arms 1006 are provided. It is also rotatably connected to a first swing arm pin 1009; a group of rear swing arms 1007 are also provided with ribs 1008, and the ends of a group of rear swing arms 1007 are also rotatably connected to a second swing arm pin 1010. When the L-shaped swing arm member 1004 is applied to the cylinder system 4 in the vehicle, the second swing arm pin 1010 is rotatably connected to the first transmission shaft 9; when the L-shaped swing arm member 1004 is applied to the rear cylinder system 5, the second swing arm pin 1010 is rotatably connected to the second transmission shaft 11.

[0053] The swing bearing seats 1011 include two, and the two swing bearing seats 1011 are respectively slidably mounted on the two transmission tubes 3. At the same time, the two swing bearing seats 1011 are fixedly installed on the middle wall panel 101. In addition, each swing bearing seat 1011 is provided with an outer swing seat 1012 which is rotated by a swing bearing. The top of the outer swing seat 1012 is hinged to the hinge end of the herringbone arm assembly, and the bottom of the outer swing seat 1012 is connected to the end of the first swing arm pin shaft 1009 through a connecting rod mechanism.

[0054] It should be noted that the herringbone arm assembly is a prior art that is used in conjunction with the air frame lifting mechanism and the air frame inner and outer swing mechanism of the colony system. Therefore, it will not be elaborated in detail here, and only its role as a connector in the air frame inner and outer swing mechanism will be applied. In addition, as Figure 3 As shown, the connecting rod mechanism includes a joint connecting rod 1013 connected to the end of the first swing arm pin 1009, the other end of the joint connecting rod 1013 is connected to one end of the swing arm rod 1014, and the other end of the swing arm rod 1014 is connected to the bottom of the outer swing seat 1012.

[0055] At this point, taking the cylinder system 4 in the car as an example, when the output end of the first cylinder 403 is extended, its output end pushes the first transmission shaft 9 from the car middle part of the spinning frame body 1 to the car head direction through the cylinder joint 8. At this time, since the second swing arm pin 1010 is rotatably connected with the first transmission shaft 9, the movement of the first transmission shaft 9 drives the L-shaped swing arm part 1004 to rotate from the car middle part of the spinning frame body 1 to the car head direction with the rotating sleeve 1005 as the axis. At this time, a group of front swing arms 1006 rotate upward in the same direction as mentioned above and drive the joint connecting rod 101 3. The end of the swing arm 1014 connected to the joint connecting rod 1013 moves upward, which causes the end of the swing arm 1014 connected to the bottom of the outer swing seat 1012 to move toward the spinning frame body 1 and the top of the outer swing seat 1012 to move away from the spinning frame body 1. Based on the connection of the herringbone arm assembly to the air frame 2 and the transmission tube 3, the air frame 2 realizes the outward swing action in the direction away from the spinning frame body 1; similarly, when the output end of the first cylinder 403 is recovered, the air frame 2 realizes the inward swing action in the direction close to the spinning frame body 1.

[0056] In the present invention, in addition to acting on the entire inward and outward swinging movement of the air rack 2, the dual-cylinder system is also used to suspend the inward and outward swinging movement of the air rack 2 when the colony system is in an intermediate state. The above-mentioned intermediate state of the colony system means that when the colony system uses the control system to control the coordinated operation of various mechanisms, after the air rack 2 is swung outward, it is necessary to wait for the air rack lifting mechanism to perform the lifting movement of the air rack 2. At this time, the air rack inward and outward swinging mechanism needs to be suspended, that is, the dual-cylinder system needs to be suspended, and this process requires the intervention of the limit system 6.

[0057] In this technical solution, if Figure 3-4 As shown, the limiting system 6 includes two limiting cylinders 601, and the two limiting cylinders 601 are respectively arranged on one side of the first cylinder 403 and the second cylinder 502 through the third mounting seat 602. The output end of the limiting cylinder 601 is provided with a slider 603, and the slider 603 is limited and slides in the preset sliding grooves on the first cylinder 403 and the second cylinder 502. In addition, the end of the slider 603 is also provided with an abutment bolt 604, and the extension direction of the abutment bolt 604 is the same as the running direction of the first cylinder 403 and the second cylinder 502.

[0058] Based on the above embodiment, when the gathering system of the spinning frame is in the middle state, the abutment bolts 604 of the two limiting cylinders 601 respectively cooperate with and abut against the limiting parts 802 in the two cylinder joints 8 close to the side of the first cylinder 403 and the second cylinder 502, which are used to control the return pause of the first cylinder 403 and the second cylinder 502.

[0059] Based on the above structure, the dual-cylinder system for the inward and outward swing of the extra-long spinning frame air frame provided by the present invention can reduce the influence of the temperature on the transmission shaft and avoid the misalignment failure of the air frame grabbing and inserting actions of the spinning frame collection system during operation to drive the inward and outward swing of the air frame 2. In this dual-cylinder system, the action of each cylinder needs to be controlled by the pneumatic control system 7.

[0060] As another innovative point of the present invention, Figure 7 As shown, the pneumatic control system 7 includes a control box 701, which is arranged on the spinning frame body 1 and is located between the first cylinder 403 and the second cylinder 502. The control box 701 is provided with a first solenoid valve and a second solenoid valve for controlling the first cylinder 403 and the second cylinder 502 respectively, and a third solenoid valve and a fourth solenoid valve for controlling the two limit cylinders 601 respectively. In addition, the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are respectively connected to the first cylinder 403, the second cylinder 502, and the two limit cylinders 601 through a number of air paths.

[0061] Based on the above embodiment, the control box 701 is arranged between the first cylinder 403 and the second cylinder 502, so that the air path length between the first solenoid valve and the first cylinder 403 is equal to the air path length between the second solenoid valve and the second cylinder 502; similarly, the air path length between the third solenoid valve and the limit cylinder 601 on the side of the first cylinder 403 is equal to the air path length between the fourth solenoid valve and the limit cylinder 601 on the side of the second cylinder 502. This arrangement ensures the synchronous control of the pneumatic control system 7 on the first cylinder 403 and the second cylinder 502, and also ensures the synchronous control of the two limit cylinders 601, thereby preventing the generation of control time difference and causing misalignment failure in the colonization process.

[0062] In the present invention, each solenoid valve is jointly controlled by the control system in the spinning frame's own cluster system on the basis of the coordinated cooperation of various mechanisms. Its control process is a common signal connection, so it will not be elaborated here; in addition, in the pneumatic control system 7, the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are all connected to the external air source.
