Description

Technical Field

[0001] This invention relates to the field of warp beam processing technology, and in particular to welding equipment and methods for assembling wide warp beams on anti-sway and stable transport upper axle carts. Background Technology

[0002] The warp beam is a selvage-mounted beam located at the rear of the loom in the weaving process, specifically designed to carry and continuously feed warp yarns. It is made by sizing several warp beams after warping, combining them (or separating and reversing the warp beams), and then threading them through heddles and reeds. The number of warp yarns wound on the beam is equal to the total number of warp yarns in the fabric. During weaving, the warp yarns unwind from the warp beam and pass sequentially through the back beam, stop warp plate, heddle eye, and reed. Together with the shedding, weft insertion, beat-up, and fabric winding, it forms the fabric. It is a key component that connects the pre-weaving process with the weaving process and determines the stability of warp yarn tension and the quality of the fabric surface.

[0003] For example, the prior art announcement CN219652615U discloses a fully automatic double-layer loom with a hem frame upper axle carriage, which includes a frame and a fixed frame. The fixed frame is welded to the top of the frame. The fixed frame is provided with a lifting mechanism for lifting objects. The outer side of the frame is provided with a support component for supporting the objects. The bottom of the frame is provided with a moving component for moving the frame. In use, the lifting cylinder drives the second mast to descend. When the second mast descends, it can drive the first mast, support block, support shaft, axle seat, first rotating cylinder, sleeve frame, first fixing pin and first tow hook to rise.

[0004] In the existing technology, when welding the shaft and disc of the warp beam, the two processes are first carried out by welding equipment and then assembled on the loom by a shaft mounting machine. The two processes need to be carried out separately. The shaft and disc cannot be directly welded by the shaft mounting machine and then assembled. In addition, the existing shaft mounting machine does not have the function of adjusting the position of the disc. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] This invention provides welding equipment and method for assembling wide-width warp beams on a stable transport vehicle to prevent swaying, which solves the problem of not being able to adjust the position of the warp beam when welding it in the prior art. The specific solution is as follows: On one hand, the present invention provides a welding device for assembling a wide-width warp beam on a stable transport vehicle with anti-sway function, including a base, a support arm, and a lifting frame. The lifting frame moves up and down along the support arm, and the shaft is placed on the lifting frame. Two discs are respectively hoisted by a hoisting device at both ends of the shaft for welding. The two discs have welding heads on their opposite sides. The welding heads move axially along the welding positions of the discs and shaft under the drive of the drive component to complete the welding. The two discs have an adjusting component on the side near the support arm. The adjusting component is U-shaped and can hold the discs in place to drive the discs to move axially along the shaft.

[0007] Preferably, the support arm is fixed to the top of the base, and the end of the support arm near the lifting frame has a slide rail. There is a slide rod between the slide rail and the support arm. The lifting frame includes a sliding member. The cross-section of the sliding member matches the cross-section of the slide rail and the slide rod. The sliding member is slidably connected to the slide rod and the slide rail. Extension arms are symmetrically fixed to both ends of the sliding member. A bracket is fixedly installed at the end of the extension arm away from the sliding member. The end of the bracket has a circular groove that matches the shaft. The shaft is placed in the circular groove.

[0008] Preferably, a telescopic drive assembly is provided between the adjusting member and the support arm, the telescopic drive assembly being used to synchronously adjust the distance between the two adjusting members.

[0009] Preferably, the telescopic component includes a sliding block with a threaded hole at one end near the support arm. A dual-axis motor is installed at the rear end of the support arm, and threaded rods are installed on the two drive shafts of the dual-axis motor. The ends of the threaded rods are threadedly connected to the threaded holes, and the two threaded holes and the two threaded rods are symmetrical to each other, so that the two sliding blocks move closer or further apart synchronously.

[0010] Preferably, a rotating sleeve is fixedly connected to one end of the sliding block near the adjusting member, and a rotating column is fixedly connected to one end of the adjusting member near the sliding block. The rotating column is rotatably connected to the rotating sleeve, and the outer wall of the rotating column has a groove to limit the rotation of the rotating column and the rotating sleeve to only allow them to rotate relative to each other.

[0011] Preferably, a clearance motor is installed on the top of the sliding block, and a first drive gear is fixedly connected to the output end of the clearance motor. A first driven gear is fixedly connected to the end of the rotating column near the first drive gear. The first driven gear meshes with the first drive gear, thereby driving the rotating column to rotate through the clearance motor, so that the adjusting component can avoid the disc body.

[0012] Preferably, a through hole is provided in the middle of the rotating column, and a limit rod is slidably installed inside the through hole. The limit rod has baffles at both ends, and a stop post is provided at the end of the baffle near the shaft. The stop post abuts against the outer wall of the shaft, so that one end of the baffle is attached to the end of the shaft. The limit rod is connected to the support arm by an elastic element. The elastic element is used to make the limit rod generate a pulling force in the direction of the support arm, thereby bringing the shaft closer to the middle of the support arm and preventing displacement.

[0013] Preferably, a limiting sleeve is fixedly connected to the rear end of the support arm, one end of the limiting rod is slidably connected to the limiting sleeve, and a spring is fixedly connected between the end of the limiting rod and the inner wall of the limiting sleeve. The spring always stretches the limiting rod toward the support arm.

[0014] Preferably, support rods are fixed to both ends of the base, a welding shaft is rotatably mounted on the top of the support rods, a welding head is fixed on the welding shaft, a welding machine is also fixed on the welding shaft, the welding head is aligned with the welding position of the shaft and the disc, a second driven gear is fixed to one end of the welding shaft, a second drive gear meshes below the second driven gear, a motor base is fixed to the top of the support rod, a welding motor is mounted on the motor base, the second drive gear is connected to the output end of the welding motor, a drive ring is rotatably connected to the welding shaft, and a telescopic rod is fixed between the bottom of the drive ring and the support rod.

[0015] On the other hand, the present invention provides a welding method for assembling a wide-width warp beam on a stable transport vehicle to prevent swaying, comprising the following steps: S1. Place the shaft to be welded on the lifting frame; S2. Using hoisting equipment, the two discs are respectively hoisted to both ends of the shaft, so that the discs are in a state ready for welding; S3. Use the U-shaped adjusting piece set on the side of the two discs near the support arm to lock the discs and drive the discs to move along the shaft axis to adjust the axial relative position of the discs and the shaft. S4. Start the drive assembly to drive the welding head located on the opposite side of the two discs to move axially along the welding position of the disc and the shaft, thereby completing the welding between the disc and the shaft.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. This invention integrates welding positioning and transportation assembly functions into one through the integrated design of the base, support arm, and lifting frame, solving the problem of separating welding and assembly processes on the upper axle car in existing technologies. The axle can be directly placed on the bracket of the lifting frame for welding, and after welding, it can be directly transported to the loom for assembly without secondary hoisting, effectively avoiding errors caused by repeated positioning and significantly improving the processing and assembly efficiency of wide-width warp beams.

[0017] 2. The lifting frame of this invention, through the precise sliding cooperation of the sliding parts with the slide rails and slide rods, can smoothly rise and fall along the support arm, adapting to warp beams of different diameters. The circular groove at the end of the bracket effectively limits the rolling range of the shaft, preventing axial movement or rolling during welding, ensuring the stability and safety of the welding operation, and improving the quality of the weld formation.

[0018] 3. This invention uses a dual-axis motor to synchronously drive a threaded rod, causing two sliding blocks to move synchronously towards or away from each other along a sliding sleeve. This allows for precise adjustment of the axial position of the disc on the shaft via an adjusting mechanism. This synchronous adjustment mechanism ensures the coaxiality of the discs at both ends, solving the problem of traditional upper shaft machines being unable to adjust the disc position, and significantly improving the welding accuracy and dynamic balance performance of the weaving beam.

[0019] 4. This invention utilizes the rotational engagement of the rotating column and the rotating sleeve to allow the adjusting component to rotate to an avoidance state under the drive of the avoidance motor, facilitating the placement and removal of the warp beam after welding. Simultaneously, under the tension of the spring, the limiting rod, through the abutment column, consistently brings the shaft towards the center of the support arm, automatically correcting the shaft's placement position and effectively preventing displacement of the shaft during welding, further ensuring welding accuracy.

[0020] 5. The welding shaft of this invention has an adjustable height position via a telescopic rod, allowing the welding head to adapt to the welding requirements of discs of different specifications. The special meshing design of the second driven gear and the second driving gear ensures uninterrupted power transmission when the welding shaft changes position. This structure enables the equipment to flexibly handle welding tasks at different positions on wide-width warp beams, enhancing the equipment's versatility and operational flexibility.

[0021] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a welding device for assembling a wide-width warp beam on a stable transport vehicle to prevent swaying. The device includes a base 1, a support arm 2, and a lifting frame 3. The lifting frame 3 moves up and down along the support arm 2, and the warp beam 4 is placed on the lifting frame 3.

[0026] The support arm 2 is fixed to the top of the base 1. The end of the support arm 2 near the lifting frame has a slide rail 5, and there is a slide rod (not shown in the figure) between the slide rail 5 and the support arm 2.

[0027] like Figure 3 As shown, the lifting frame 3 includes a sliding member 6. The cross-section of the sliding member matches the cross-section of the slide rail 5 and the slide rod. The sliding member 6 is slidably connected to the slide rod and the slide rail 5. Extension arms 7 are symmetrically fixed to both ends of the sliding member 6. A bracket 8 is fixedly installed at the end of the extension arm 7 away from the sliding member 6. The end of the bracket 8 has a circular groove 9 that matches the shaft 4. The shaft 4 is placed in the circular groove 9, thereby limiting the rolling range of the shaft 4.

[0028] like Figure 2As shown, the discs 10 of the two warp beams are respectively hoisted at both ends of the shaft body 4 by a hoisting device (not shown in the figure) for welding. The two discs 10 have welding heads 11 on the opposite sides. The welding heads 11 move axially along the welding positions of the discs 10 and shaft body 4 under the drive of the drive assembly to complete the welding.

[0029] like Figure 4 As shown, each of the two discs 10 has an adjusting member 12 on the side near the support arm 2. The adjusting member 12 is U-shaped and can hold the disc 10 in place to drive the disc 10 to move along the axial direction of the shaft 4, thereby adjusting the relative position of the disc 10 and the shaft 4.

[0030] There is a telescopic drive assembly between the adjusting member 12 and the support arm 2. The telescopic drive assembly is used to synchronously adjust the distance between the two adjusting members 12.

[0031] like Figure 4 , Figure 5 As shown, the telescopic assembly includes a sliding block 13. A threaded hole 14 is provided at one end of the sliding block 13 near the support arm 2. A dual-axis motor 15 is installed at the rear end of the support arm. Threaded rods 16 are respectively installed on the two drive shafts of the dual-axis motor 15. The ends of the threaded rods 16 are threadedly connected to the threaded holes 14. The two threaded holes 14 and the two threaded rods 16 are symmetrical to each other, so that the two sliding blocks 13 can move closer or further apart synchronously. A sliding sleeve 17 is fixedly connected to the rear end of the support arm 2. The sliding block 13 is slidably connected to the sliding sleeve 17. The cross-sections of the sliding sleeve 17 and the sliding block 13 are non-circular. Therefore, when the dual-axis motor 15 drives the threaded rods 16 to rotate, it can drive the sliding block 13 to move along the sliding sleeve 17, thereby allowing the adjusting member 12 to move with the sliding block 13, thus adjusting the position of the disc body 10.

[0032] like Figure 4 As shown, a rotating sleeve 18 is fixedly connected to one end of the sliding block 13 near the adjusting member 12, and a rotating column 19 is fixedly connected to one end of the adjusting member 12 near the sliding block 13. The rotating column 19 is rotatably connected to the rotating sleeve 18. The outer wall of the rotating column 19 has a groove, which is used to allow the rotating column 19 and the rotating sleeve 18 to rotate relative to each other but not slide relative to each other.

[0033] A clearance motor 20 is mounted on the top of the sliding block 13. A first drive gear 21 is fixedly connected to the output end of the clearance motor 20. A first driven gear 22 is fixedly connected to the end of the rotating column 19 near the first drive gear 21. The first driven gear 22 meshes with the first drive gear 21, thereby driving the rotating column 19 to rotate through the clearance motor 20, thus allowing the adjusting member 12 to avoid the disc body 10 (e.g., Figure 5 (The avoidance state shown).

[0034] As one possible implementation, such as Figure 4 , Figure 5 , Figure 6 As shown, a through hole 23 is provided in the middle of the rotating column 19. A limit rod 24 is slidably installed inside the through hole 23. Both ends of the limit rod 24 have baffles 25. The end of the baffle 25 near the shaft 4 has a stop post 26. The stop post 26 abuts against the outer wall of the shaft 4, so that one end of the baffle 25 is attached to the end of the shaft 4. The limit rod 24 is connected to the support arm 2 by an elastic element. The elastic element is used to make the limit rod 24 generate a pulling force in the direction of the support arm 2, thereby bringing the shaft 4 closer to the middle of the support arm 2 and preventing it from shifting.

[0035] The rear end of the support arm 2 is fixedly connected to the limiting sleeve 27. One end of the limiting rod 24 is slidably connected to the limiting sleeve 27. A spring 28 is fixedly connected between the end of the limiting rod 24 and the inner wall of the limiting sleeve 27. The spring 28 always stretches the limiting rod 24 toward the support arm 2.

[0036] like Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, support rods 29 are fixed to both ends of the base 1. A welding shaft 30 is rotatably mounted on the top of the support rods 29. A welding head 11 is fixed on the welding shaft 30. A welding machine 31 is also fixed on the welding shaft 30. The welding head 11 is aligned with the welding positions of the shaft 4 and the disc 10. A second driven gear 32 is fixed to one end of the welding shaft 30. A second drive gear 33 meshes below the second driven gear 32. A motor base 34 is fixed to the top of the support rods 29. A welding motor 35 is mounted on the motor base 34. The second drive gear 33 is connected to the output end of the welding motor 35. A drive ring 36 is also rotatably connected to the welding shaft 30. A telescopic rod 37 is fixed between the bottom of the drive ring 36 and the support rod 29.

[0037] In the above scheme, the position of the welding shaft 30 is adjusted by the telescopic rod 37, so that the welding head 11 can weld the weaving shaft at different positions of the disc 10. Furthermore, the teeth of the second driven gear 32 are relatively long, so that even if the position of the welding shaft 30 changes, the second drive gear 33 can still mesh with the second driven gear 32.

[0038] Example 2: Figure 1 , Figure 10 As shown, the technical solution of this embodiment differs from that of Embodiment 1 in that this embodiment provides a welding method for assembling a wide-width warp beam on a stable transport vehicle to prevent swaying, including the following steps: S1. First, place the wide-width warp beam 4 stably on the brackets 8 at both ends of the lifting frame 3. The ends of the brackets 8 have circular grooves 9 that match the warp beam 4. These grooves effectively limit the rolling range of the warp beam 4, preventing it from rolling or axially shifting during subsequent operations or welding. The lifting frame 3 is slidably connected to the slide rails 5 and internal slide rods on the support arm 2 via sliding members 6, allowing the lifting frame 3 to move smoothly up and down along the support arm 2, thus adapting to the placement requirements of warp beams of different diameters. The support arm 2 is securely fixed to the top of the base 1, providing a solid support foundation for the entire equipment.

[0039] S2. Using external hoisting equipment, the two discs 10 are respectively hoisted to both ends of the shaft 4, so that the discs 10 and the shaft 4 are initially connected, ready for welding. At this time, the two discs 10 are respectively held by the adjusting parts 12 on the side near the support arm 2. The adjusting parts 12 are U-shaped and can fit tightly against the edge of the disc 10, thus having the ability to move the discs 10.

[0040] S3. Start the dual-axis motor 15 in the telescopic drive assembly. The two drive shafts of the dual-axis motor 15 drive the two threaded rods 16 to rotate synchronously. Since the two sliding blocks 13 at the rear end of the support arm 2 have threaded holes 14, and the ends of the threaded rods 16 are threadedly connected to the threaded holes 14, and the two threaded holes 14 and the two threaded rods 16 are symmetrically arranged, when the threaded rods 16 rotate, they will drive the two sliding blocks 13 to move closer or further apart synchronously. At the same time, a sliding sleeve 17 is fixedly connected to the rear end of the support arm 2, and the sliding blocks 13 are slidably connected to the sliding sleeve 17. The cross-sections of the sliding sleeve 17 and the sliding blocks 13 are both non-circular, which ensures that the sliding blocks 13 can only move linearly along the sliding sleeve 17 and cannot rotate. The movement of the sliding blocks 13 directly drives the adjusting component 12 to move axially along the shaft 4, thereby synchronously and accurately adjusting the distance between the two discs 10 and ensuring the coaxiality of the discs 10 and the shaft 4.

[0041] During the adjustment of the position of the disc 10, the centering and limiting of the shaft 4 are also performed simultaneously. A through hole 23 is provided in the middle of the rotating column 19, and the limiting rod 24 is slidably installed in this through hole 23. The baffles 25 at both ends of the limiting rod 24 have abutment posts 26 near the end of the shaft 4. Simultaneously, the end of the limiting rod 24 is slidably connected to the limiting sleeve 27 fixed to the rear end of the support arm 2, and a spring 28 is fixed between the end of the limiting rod 24 and the inner wall of the limiting sleeve 27. The spring 28 is always in a stretched state, generating a pulling force that pulls the limiting rod 24 towards the support arm 2. Under this pulling force, the abutment post 26 presses tightly against the outer wall of the shaft 4, bringing the shaft 4 closer to the center of the support arm 2, effectively preventing the shaft 4 from shifting before welding and further ensuring welding accuracy.

[0042] S4. After the positions of the disc 10 and the shaft 4 are adjusted and confirmed to be coaxial, the welding operation begins. The support rod 29 is fixed to both ends of the base 1, and a welding shaft 30 is rotatably mounted on its top. A welding machine 31 is fixed on the welding shaft 30, and the welding head 11 is aligned with the welding positions of the shaft 4 and the disc 10. The welding motor 35 on the motor base 34 is started, and the output end of the welding motor 35 drives the second drive gear 33 to rotate. The second drive gear 33 meshes with the second driven gear 32 fixed to one end of the welding shaft 30, thereby driving the welding shaft 30 to rotate, so that the welding head 11 can perform axial or circumferential welding operations along the welding positions of the disc 10 and the shaft 4.

[0043] S5. By controlling the extension and retraction of the telescopic rod 37, the drive ring 36 can be pushed and the welding shaft 30 can be moved as a whole, thereby changing the welding position of the welding head 11. Since the teeth of the second driven gear 32 are designed to be longer, even if the axial position of the welding shaft 30 changes, the second drive gear 33 can still maintain a good meshing state with the second driven gear 32, ensuring that the power transmission is not interrupted.

[0044] S6. After the welding operation is completed, the welded warp beam needs to be removed from the equipment. At this time, the avoidance motor 20 on the top of the sliding block 13 is started, and the output end of the avoidance motor 20 drives the first drive gear 21 to rotate. The first drive gear 21 meshes with the first driven gear 22 fixed to the end of the rotating column 19, thereby driving the rotating column 19 to rotate within the rotating sleeve 18. Since the adjusting component 12 is fixed to the rotating column 19, and the rotating column 19 and the rotating sleeve 18 can only rotate relative to each other and cannot slide relative to each other through the groove fit, the rotation of the rotating column 19 will drive the adjusting component 12 to rotate accordingly, changing it from the state of being stuck on the disc body 10 to the avoidance state, thereby releasing the constraint on the disc body 10. At this time, the lifting frame 3 can be lowered or, with the help of the hoisting equipment, the welded warp beam can be easily removed from the circular groove 9 of the bracket 8, completing the anti-sway stable transportation, welding and assembly preparation work of the entire wide warp beam.

[0045] In summary, this invention integrates the base 1, support arm 2, and lifting frame 3, combining welding positioning and transportation assembly functions into one, solving the problem of separating welding and upper axle assembly processes in existing technologies. The shaft 4 can be directly placed on the bracket 8 of the lifting frame 3 for welding, and after welding, it can be directly transported to the loom for assembly without secondary hoisting, effectively avoiding errors caused by repeated positioning and significantly improving the processing and assembly efficiency of wide-width warp beams. The lifting frame 3, through the precise sliding cooperation of the sliding element 6, slide rail 5, and slide rod, can smoothly rise and fall along the support arm 2, adapting to warp beams of different diameters. The circular groove 9 at the end of the bracket 8 effectively limits the rolling range of the shaft 4, preventing axial movement or rolling during welding, ensuring the stability and safety of the welding operation, and improving the weld formation quality. The dual-axis motor 15 synchronously drives the threaded rod 16, causing two sliding blocks 13 to move synchronously towards or away from each other along the sliding sleeve 17, thereby precisely adjusting the axial position of the disc 10 on the shaft 4 through the adjusting element 12. This synchronous adjustment mechanism ensures the coaxiality of the two end discs 10, solving the problem of traditional upper axle machines being unable to adjust the disc position, and significantly improving the welding accuracy and dynamic balance performance of the warp beam. Through the rotational engagement of the rotating column 19 and the rotating sleeve 18, the adjusting component 12 can be rotated to the avoidance state under the drive of the avoidance motor 20, facilitating the placement and removal of the warp beam after welding. Simultaneously, under the tension of the spring 28, the limiting rod 24, through the abutment column 26, constantly keeps the shaft 4 close to the center of the support arm 2, automatically correcting the placement position of the shaft 4, effectively preventing the shaft 4 from shifting during the welding process, further ensuring welding accuracy. The welding shaft 30's height position is adjusted via the telescopic rod 37, allowing the welding head 11 to adapt to the welding requirements of different sized discs 10. The special meshing design of the second driven gear 32 and the second driving gear 33 ensures uninterrupted power transmission when the welding shaft 30's position changes. This structure enables the equipment to flexibly handle welding tasks at different positions on wide warp beams, enhancing the equipment's versatility and operational flexibility.
