Description

Technical Field

[0001] This invention relates to the field of transfer structure technology, and more particularly to an apparatus for transferring stainless steel pipes. Background Technology

[0002] In the production and processing of stainless steel pipes, the inkjet printing process is a crucial step. Its main function is to mark key information such as specifications, material, and production batch on the surface of the steel pipes, facilitating subsequent product traceability, warehousing management, and market circulation. After the inkjet printing is completed, the stainless steel pipes need to be promptly transferred to the conveyor line to enter the next processing, inspection, or packaging process. The smoothness and stability of this transfer process directly affect the efficiency of the entire production line and the product quality.

[0003] Currently, the industry mostly uses traditional methods for transferring inkjet-coded stainless steel pipes to the conveyor line. Manual handling relies on operators manually moving the inkjet-coded stainless steel pipes from the inkjet printing station to the conveyor line. This method not only consumes a lot of labor costs but is also inefficient, making it difficult to adapt to the high-efficiency operation requirements of modern production lines. Furthermore, during manual handling, operators have difficulty precisely controlling the grip and angle of the steel pipes, which can easily lead to friction damage to the inkjet-coded information on the pipe surface, or scratches and deformation caused by collisions during handling, affecting the product's appearance and quality.

[0004] As the stainless steel pipe manufacturing industry continues to demand higher levels of automation, production efficiency, and product quality, the problems of low efficiency, easy product damage, and poor stability of traditional transfer methods are becoming increasingly prominent, and they can no longer meet the actual operational needs of modern production lines. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a device for transferring stainless steel pipes to avoid affecting production continuity and to meet the operational requirements of modern production lines.

[0006] The technical solution of the present invention: a device for transferring stainless steel pipes, the device comprising a buffer rack, a feeding mechanism, a baffle and a transfer assembly;

[0007] The feeding mechanism is installed on one side of the buffer rack. The feeding mechanism is used to move the stainless steel tube to the inkjet printing station, and at the same time, the feeding mechanism moves the stainless steel tube out of the inkjet printing station after the inkjet printing operation.

[0008] The feeding mechanism includes multiple groups of top plates rotatably connected to the bottom of the inclined rod, and a synchronous rod is fixedly connected to the bottoms of the multiple groups of top plates; a first card slot, a second card slot and an anti - detachment part are formed on the top of the top plate; a pushing component is arranged below the top plate, and the pushing component includes a positioning seat, a push rod and a connecting frame. The positioning seat is arranged on the fixed rod, and the push rod is rotatably connected to the top of the positioning seat; the output end of the push rod is fixedly connected to the connecting frame, and the connecting frame is clamped on the bottom of the top plate and is rotatably connected to it;

[0009] The baffle is fixedly connected to the side of the inclined rod, and a positioning groove is formed on it; multiple groups of baffles are used to position the stainless steel pipes;

[0010] The transfer component includes multiple groups of fixed columns. A servo - motor is arranged on one group of fixed columns and a rotating shaft is arranged through a bearing. On both sides of the other group of fixed columns, mounting plates are respectively fixedly connected. A first synchronous pulley is rotatably connected to the side of one mounting plate, and a second synchronous pulley is rotatably connected to the side of the other mounting plate; on the side of the fixed column below one group of mounting plates, a mounting frame is installed, and a third synchronous pulley is rotatably connected inside the mounting frame; a first synchronous belt is sleeved on the first synchronous pulley, the second synchronous pulley and the third synchronous pulley together; multiple groups of blocks are installed on the first synchronous belt and are arranged in an equidistant array, and a V - shaped groove is formed on the top of each block;

[0011] The rotating shaft penetrates through multiple groups of mounting plates and is rotatably connected to them. Multiple groups of fifth synchronous pulleys and first synchronous pulleys are fixedly arranged on the rotating shaft;

[0012] The output end of the servo - motor is provided with a fourth synchronous pulley, and a second synchronous belt is sleeved on the fourth synchronous pulley and the fifth synchronous pulley;

[0013] The transfer component is used to transfer the stainless steel pipes to the assembly line. The servo - motor drives the fourth synchronous pulley to rotate,带动 the fifth synchronous pulley and the rotating shaft to rotate. The first synchronous pulley fixedly connected to the rotating shaft then带动 the first synchronous belt to rotate, and then the blocks act on the stainless steel pipes to带动 them to move.

[0014] Further, the buffer rack includes multiple groups of inclined rods arranged obliquely. The inclined rods are supported by multiple groups of fixed rods, and connecting rods are fixedly connected between the multiple groups of fixed rods.

[0015] Further, the anti - detachment part is arranged at one end of the top plate away from the inclined rod.

[0016] Further, the connecting frame and the mounting frame are arranged in a "U" shape.

[0017] Further, the first synchronous belt and the second synchronous belt are chains or belts, and the first synchronous pulley, the second synchronous pulley, the third synchronous pulley, the fourth synchronous pulley and the fifth synchronous pulley are corresponding sprockets or belt pulleys for the first synchronous belt and the second synchronous belt.

[0018] The beneficial effects of this invention are as follows: This device uses a servo motor to drive multiple sets of first synchronous belts and clamps to move synchronously, continuously transferring stainless steel tubes from the anti-detachment section to the production line. The entire process requires no downtime, and the connections between each step are tight, adapting to the continuous operation requirements of modern production lines. The synchronous movement of the first and second synchronous belts avoids deformation of the stainless steel tubes due to transmission deviations. Simultaneously, the stable transfer process prevents the inkjet printing information from becoming blurred or falling off due to friction and collision, ensuring the integrity of product markings. This significantly improves transfer efficiency, ensures product quality, and meets the needs of modern production lines. Attached Figure Description

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example

[0026] like Figure 1As shown, the device for transferring stainless steel pipes proposed in this invention includes a buffer rack 1 for holding the stainless steel pipes. The buffer rack 1 includes multiple sets of inclined rods 11, and the stainless steel pipes roll along the inclined rods 11. Multiple sets of fixing rods 12 are fixedly connected to the bottom of the inclined rods 11, and connecting rods 13 are fixedly connected between the multiple sets of fixing rods 12. The arrangement of the fixing rods 12 and the connecting rods 13 makes the position of the inclined rods 11 stable.

[0027] For further details, please refer to Figure 2 and Figure 3 The aforementioned transfer structure includes a feeding mechanism 2 installed on one side of the buffer rack 1. The feeding mechanism 2 is used to move the stainless steel tube to the inkjet printing station, and simultaneously removes the stainless steel tube from the inkjet printing station after the inkjet printing operation. The feeding mechanism 2 includes multiple sets of top plates 21, which are rotatably connected to the bottom of the inclined rod 11. The bottom of the multiple sets of top plates 21 is fixedly connected to a synchronizing rod 22, which enables the multiple sets of top plates 21 to deflect synchronously. The top of the top plate 21 is provided with a first slot 211, a second slot 212, and an anti-detachment part 213. The anti-detachment part 213 is located at the end of the top plate 21 away from the inclined rod 11 and is used to position the stainless steel tube. A positioning seat 23 is provided below the top plate 21. The positioning seat 23 is fixedly connected to the side of the fixing rod 12. A push rod 24 is rotatably connected to the top of the positioning seat 23. A connecting frame 25 is fixedly connected to the output end of the push rod 24. The connecting frame 25 is U-shaped and is locked into the bottom of the top plate 21 and rotatably connected to it. After starting, the push rod 24 drives the top plate 21 to deflect through the connecting frame 25. At the same time, the push rod 24 can deflect to match the rotation of the top plate 21 because it is rotatably connected to the positioning seat 23. Multiple sets of push rods 24 are synchronously controlled by the control box to ensure synchronous operation and the same stroke.

[0028] The baffle 3 is used to position the stainless steel pipe. The baffle 3 is fixedly connected to the side of the diagonal rod 11 and has a positioning groove 31. The stainless steel pipe is positioned after being inserted into the positioning groove 31.

[0029] It is worth mentioning that the positioning and discharge process of the stainless steel tube is as follows: After rolling on the inclined rod 11, the stainless steel tube is first positioned in the first slot 211. After the top plate 21 deflects downward, the stainless steel tube contacts the sides of multiple sets of baffles 3, and at the same time, the stainless steel tube is above the first slot 211. Then, the top plate 21 deflects upward, lifting the stainless steel tube. At this time, the stainless steel tube is above the baffle 3 and is positioned in the second slot 212. Then, the top plate 21 deflects downward again, and the bottom of the stainless steel tube contacts the positioning groove 31. After the top plate 21 separates from the stainless steel tube, the stainless steel tube rolls to the lowest point of the positioning groove 31 to achieve positioning. At this time, the second slot 212 is below the stainless steel tube. Finally, the top plate 21 deflects upward again, lifting the stainless steel tube. After the stainless steel tube moves away from the baffle 3, it rolls along the top plate 21 to the anti-detachment part 213 at one end, facilitating the discharge of the stainless steel tube.

[0030] Specifically, the transfer assembly 4 is used to transfer stainless steel pipes to the production line. The transfer assembly 4 includes multiple sets of fixed columns 41. One set of fixed columns 41 is equipped with a servo motor 47 and a rotating shaft 411 mounted on a bearing. Mounting plates 412 are fixedly connected to both sides of another set of fixed columns 41. A first synchronous pulley 42 is rotatably connected to the side of one set of mounting plates 412, and a second synchronous pulley 43 is rotatably connected to the side of the other set of mounting plates 412. Both the first and second synchronous pulleys 42 and 43 rotate in their original positions. A mounting frame 413 is mounted on the side of the fixed columns 41. The mounting frame 413 is U-shaped and rotatably connected to a third synchronous pulley 44, which keeps the third synchronous pulley 44 rotating in its original position. A first synchronous belt 45 is fitted onto the first, second, and third synchronous pulleys 42, and the first synchronous belt 45 is triangular in shape. When the three sets of synchronous pulleys rotate synchronously, they drive the first synchronous belt 45 to move.

[0031] Multiple sets of clamping blocks 46 are installed on the first synchronous belt 45. The top of the clamping block 46 is provided with a V-shaped groove. The multiple sets of clamping blocks 46 are distributed in an equidistant array. When the first synchronous belt 45 moves, it drives the clamping blocks 46 to move cyclically. After the V-shaped groove on the top of the clamping block 46 contacts the stainless steel tube from below, as the clamping block 46 moves, it drives the stainless steel tube to rise and move away from the anti-detachment part 213, and follow the clamping block 46 away from the feeding mechanism 2.

[0032] The rotating shaft 411 passes through and is rotatably connected to multiple sets of mounting plates 412. Multiple sets of fifth synchronous pulleys 410 and first synchronous pulleys 42 are fixedly installed on the rotating shaft 411. The output end of the servo motor 47 is provided with a fourth synchronous pulley 48. A second synchronous belt 49 is sleeved and installed on the fourth synchronous pulley 48 and the fifth synchronous pulley 410. The transfer assembly 4 is used to transfer stainless steel pipes to the production line. The servo motor 47 drives the fourth synchronous pulley 48 to rotate, which drives the fifth synchronous pulley 410 and the rotating shaft 411 to rotate. The first synchronous pulley 42, which is fixedly connected to the rotating shaft 411, then drives the first synchronous belt 45 to rotate. The clamping block 46 then acts on the stainless steel pipe to move it.

[0033] The first synchronous belt 45 and the second synchronous belt 49 are chains or belts. The first synchronous pulley 42, the second synchronous pulley 43, the third synchronous pulley 44, the fourth synchronous pulley 48 and the fifth synchronous pulley 410 are sprockets or belt pulleys corresponding to the first synchronous belt 45 and the second synchronous belt 49. It is preferred to use a transmission method of sprockets and chains, which makes the transmission more stable and avoids the position of multiple sets of locking blocks 46 from shifting.

[0034] In this embodiment, the stainless steel pipe is first temporarily stored in the buffer rack 1. Multiple sets of inclined rods 11 are arranged inside the buffer rack 1, allowing the steel pipe to roll along the inclined rods 11 under its own weight, preparing for the feeding process. After rolling along the inclined rods 11, the steel pipe first engages in the first slot 211 at the top of the top plate 21, completing initial positioning and providing a stable working position for inkjet printing. The control box synchronously drives multiple sets of push rods 24, which move the connecting frame 25. The connecting frame 25 causes the top plate 21 to deflect downwards around the bottom of the inclined rods 11, causing the steel pipe to disengage from the first slot 211 and contact the sides of multiple sets of baffles 3, remaining above the first slot 211. The push rods 24 push the connecting frame 25, causing the top plate 21 to deflect upwards, lifting the steel pipe above the baffles 3, where it engages in the second slot 212 at the top of the top plate 21. The top plate 21 deflects downwards again, causing the bottom of the steel pipe to fall into the positioning groove 31 on the baffle 3, and roll along the groove to the lowest point, completing the final positioning after inkjet printing, ensuring accurate positioning. Then, push rod 24 drives top plate 21 to deflect upward again, lifting the steel pipe away from baffle 3. The steel pipe rolls along top plate 21 to end anti-detachment part 213 to prevent it from falling, preparing it for subsequent transfer to the assembly line.

[0035] The servo motor 47 on the side of the fixed column 41 is activated. The output of the servo motor 47 drives the fourth synchronous pulley 48 to rotate through the gear steering box. The fourth synchronous pulley 48 drives the fifth synchronous pulley 410 to rotate synchronously through the second synchronous belt 49. The fifth synchronous pulley 410 drives the rotating shaft 411 fixedly connected to it to rotate. The rotating shaft 411 passes through and drives the first synchronous pulleys 42 on multiple sets of mounting plates 412 to rotate synchronously. When the first synchronous pulleys 42 rotate, they drive the first synchronous belt 45 that cooperates with them to move in a cycle. Multiple sets of equidistant locking blocks 46 on the first synchronous belt 45 move in a cycle synchronously with the first synchronous belt 45. When the locking block 46 moves to below the anti-detachment part 213, the V-shaped groove on the top of the locking block 46 contacts the tube body from below. As the first synchronous belt 45 continues to move, the locking block 46 lifts the stainless steel tube from bottom to top, causing it to detach from the anti-detachment part 213. Then, the locking block 46 carries the stainless steel tube along the transmission direction of the first synchronous belt 45, finally smoothly transferring the stainless steel tube to the conveyor line, completing the entire transfer process.
