Description

Technical Field

[0001] This invention relates to the field of laser tube cutting machine technology, and more particularly to a laser tube cutting system. Background Technology

[0002] Laser tube cutting machines are high-precision CNC industrial equipment designed specifically for tubes. They use high-energy laser beams as cutting tools and non-contact thermal cutting. Combined with the tube rotation feed and the linkage of the cutting head, they can cut, open, bevel, and process irregular contours of round tubes, square tubes, rectangular tubes, elliptical tubes, angle steel, and channel steel. They are the core equipment for modern metal tube processing.

[0003] Currently, in the laser tube cutting machine processing industry, after tube processing, the tubes are generally received directly through a hopper or unloaded by a feeding machine for temporary storage. The number of tubes stored is relatively small, and most are placed haphazardly, not sorted according to length. Operators need to frequently sort and stack the tubes according to length, grouping tubes of the same length to the same location. However, sorting and stacking large or heavy tubes is difficult. This manual sorting and stacking method has low automation, relies heavily on operators, is time-consuming and labor-intensive, and results in low production efficiency. Summary of the Invention

[0040] (III) Beneficial Effects

[0041] After being cut by the laser cutting machine, the pipes are directly fed into the first buffer device. Through linkage with the control system, if the length of the currently cut pipe meets the storage conditions of the first buffer device, it is stored directly there. If not, the pipe is conveyed to the second buffer device. Similarly, if the second buffer device does not meet its storage conditions, it is conveyed to the third buffer device. If there are specific placement requirements for the pipes' posture and characteristics, the pipes are conveyed to the fourth buffer device via the third buffer device for temporary stacking and organization, facilitating further sorting and handling by a palletizing gantry robot. This invention, by conveying pipes to different buffer devices based on their length, reduces the labor intensity of manual operation, improves sorting and stacking efficiency, and thus increases production efficiency.

Detailed Implementation

[0060] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with respect to... Figure 1 The orientation is used as a reference.

[0061] While exemplary embodiments of the invention are shown in the accompanying drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention can be understood more clearly and thoroughly, and that the scope of the invention can be fully conveyed to those skilled in the art.

[0062] This invention provides a laser tube cutting system that cuts tubes to a set length and then sorts and stacks the cut tubes according to the same length.

[0063] like Figure 1As shown, the laser tube cutting system includes a laser tube cutting machine 1, a first buffer device 2, a second buffer device 3, a third buffer device 4, and a fourth buffer device 5. The first buffer device 2, the second buffer device 3, and the third buffer device 4 are arranged sequentially along a straight line to buffer tubes of different lengths, improving sorting and stacking efficiency, and thus increasing production efficiency. The first buffer device 2 is connected to the discharge port of the laser tube cutting machine 1, and the fourth buffer device 5 is connected to the third buffer device 4. The first buffer device 2, the second buffer device 3, the third buffer device 4, and the fourth buffer device 5 are used to buffer and hold at least two types of tubes of different lengths.

[0064] After being cut by the laser cutting machine, the pipes are directly fed into the first buffer device 2. Through linkage with the control system of the laser pipe cutting machine 1, if the length of the currently cut pipe meets the storage conditions of the first buffer device 2 (i.e., the pipe length conforms to the storage conditions of the first buffer device 2), this is determined by comparing the currently set cutting length of the laser pipe cutting machine 1 with the pipe length that the first buffer device 2 can store. If the cutting length is less than or equal to the storage length, the pipe is directly stored in the first buffer device 2; if it is greater, the pipe is transported to the second buffer device 3 via the first buffer device 2. Similarly, if the storage conditions of the second buffer device 3 are not met, the pipe is transported to the third buffer device 4 via the second buffer device 3. If there are specific requirements for the posture and characteristics of the pipes, the pipes are transported to the fourth buffer device 5 via the third buffer device 4 for temporary stacking and organization, facilitating further organization and handling by the palletizing gantry robot. This invention, by transporting different pipes to different buffer devices for storage according to their length, reduces the labor intensity of manual operation, improves the efficiency of sorting and stacking, and thus improves production efficiency.

[0065] like Figure 2 and Figure 3 As shown, the first buffer device 2 includes a first conveyor roller 208, a first fixed unloading plate 204, a tilting unloading plate 205, a first drive assembly 206, and a first hopper 203. The first conveyor roller 208 is preferably a V-shaped roller assembly used to receive and transport pipes. The first end of the first conveyor roller 208 is connected to the outlet of the laser pipe cutter 1, allowing the pipes cut by the laser pipe cutter 1 to fall directly onto the first conveyor roller 208. The second end of the first conveyor roller 208 is detachably connected to the second buffer device 3, allowing the pipes to be transported to the second buffer device 3 via the first conveyor roller 208.

[0066] Furthermore, the first fixed feeding plate 204, the flip-over feeding plate 205, and the first hopper 203 are arranged sequentially along a direction perpendicular to the first conveyor roller conveyor 208. The first fixed feeding plate 204 is inclinedly arranged below the laser head of the laser tube cutting machine 1. The cut tubes fall onto the first fixed feeding plate 204 and roll or slide along the inclined surface of the first fixed feeding plate 204 onto the first conveyor roller conveyor 208 or the flip-over feeding plate 205. The first fixed feeding plate 204 can both compensate for the gap and height difference between the first conveyor roller conveyor 208 and the laser tube cutting machine 1, and prevent the tubes from falling directly onto the first conveying pipe and damaging the first conveyor roller conveyor 208.

[0067] like Figure 2 and Figure 3 As shown, the first drive assembly 206 is preferably a first cylinder. The first drive assembly 206 is connected to the tilting feed plate 205 through a floating joint to drive the tilting feed plate 205 to rotate between the first state and the second state. In the first state, the flip-over unloading plate 205 covers the top of the first conveying roller 208. The first end of the flip-over unloading plate 205 is connected to the first fixed unloading plate 204, and the second end of the flip-over unloading plate 205 is located above the first hopper 203. The cut pipes roll or slide down along the first fixed unloading plate 204 and the flip-over unloading plate 205 in sequence to be temporarily stored in the first hopper 203. In the second state, the first drive assembly 206 drives the flip-over unloading plate 205 to flip onto the side of the first conveying roller 208 away from the first fixed unloading plate 204, forming a side baffle structure of the first conveying roller 208. The pipes that roll or slide down along the first fixed unloading plate 204 are blocked by the flip-over unloading plate 205 and remain on the first conveying roller 208. Then, they are transported to the second buffer device 3 as the first conveying roller 208 runs. Additionally, when the pipe is in the first state on the flip-over unloading plate 205, the angle between the flip-over unloading plate 205 and the horizontal plane can be increased by rotating the flip-over unloading plate 205, thereby improving the unloading efficiency of the pipe. Specifically, the short pipe cut by the laser cutting machine is unloaded onto the flip-over unloading plate 205 via the first fixed unloading plate 204. The first cylinder retracts, causing the flip-over unloading plate 205 to rotate clockwise, flipping the pipe into the first hopper 203 for short pipe storage. When the first hopper 203 does not meet the storage requirements, the first cylinder retracts in advance, the flip-over unloading plate 205 flips, and the pipe is unloaded onto the first conveyor roller 208 via the first fixed unloading plate 204. One end of the first conveyor roller 208 is connected to a chain assembly 207, which drives the first conveyor roller 208 to rotate, transporting the pipe to the second conveyor roller 307.

[0068] like Figure 4As shown, the first buffer device 2 also includes a first buffer frame 202, rollers 201, and a locking assembly. The first conveyor roller 208, the first fixed unloading plate 204, the flipping unloading plate 205, and the first drive assembly 206 are all mounted on the first buffer frame 202. The rollers 201 are located at the bottom of the first buffer frame 202, and the locking assembly is mounted on the first buffer frame 202. The first buffer frame 202 is detachably connected to the ground via the locking assembly. Specifically, the locking assembly includes a pin 209 mounted on the side of the first buffer frame 202, a connecting locking member 210, and a guide fixing member 211. During normal use, the plug of the pin 209 is fixed to the socket on the ground. The first conveyor roller 208 and the second conveyor roller 3073 are adjusted and kept on the same straight line by the guide fixing part 211, and then locked by the connecting locking part 210. During maintenance, the plug of the pin 209 is lifted, the connecting locking part 210 is released, and the first conveyor roller 2082 is moved out by the roller 201 for easy maintenance.

[0069] like Figure 5 As shown, the second buffer device 3 includes a second buffer frame 302 and a second conveyor roller 307, a second fixed unloading plate 303, a paddle assembly 304, a second drive assembly, and a second hopper 301 mounted on the second buffer frame 302. The second conveyor roller 307 is detachably connected to the second end of the first conveyor roller 208. The second fixed unloading plate 303 is inclinedly disposed on the first side of the second conveyor roller 307, which is the side closer to the laser tube cutter 1. The second fixed unloading plate 303 receives and guides the cut tubes onto the second conveyor roller 307. The second hopper 301 is disposed on the second side of the second conveyor roller 307, which is the side away from the laser tube cutter 1. The paddle assembly 304 is rotatably disposed on the second conveyor roller 307. The second drive assembly is connected to the paddle assembly 304 to drive the paddle assembly 304 to rotate. The paddle assembly 304 is used to paddle the tubes on the second conveyor roller 307 onto the second hopper 301.

[0070] Specifically, see Figure 5 The pipe material falls from the second fixed feeding plate 303 onto the second conveyor roller 307. A paddle is installed at the gap between the rollers of the second conveyor roller 307. Multiple paddles form a paddle assembly 304, which is connected to a drive chain 305 via a shaft and coupling. The other end of the drive chain 305 is connected to a drive motor 306. Through linkage with the control system of the laser pipe cutting machine 1, if the length of the currently cut pipe meets the storage conditions of the second buffer device 3, the drive motor 306 drives the paddle assembly 304 to rotate, transferring the pipe material from the second conveyor roller 307 to the second hopper 301.

[0071] Furthermore, the second hopper 301 includes at least a first storage area and a second storage area arranged sequentially along the conveying direction of the second conveyor roller 307. The first and second storage areas are used to store pipes of different lengths, enabling batch storage of two specifications of pipes. Specifically, two adjustable detection switches are installed at the ends and the middle of the second buffer frame 302, respectively. The detection switches detect the position of the pipe on the second conveyor roller 307, control the start and stop of the second conveyor roller 307, and use the lever assembly 304 to move the pipe to the corresponding storage area.

[0072] like Figure 6 and Figure 7 As shown, the second buffer device 3 also includes a first transmission assembly, a clutch assembly 308, and a guide assembly 309. The second end of the second conveyor roller 307 is detachably connected to the second end of the first conveyor roller 208 via the guide assembly 309 and the guide fixing member 211. The connection between the guide assembly 309 and the guide fixing member 211 is completed through the guide assembly 309, so that the second conveyor roller 307 and the first conveyor roller 208 are on the same straight line. The guide assembly 309 and the guide fixing member 211 are preferably paired slide rails and slide tracks. The first transmission assembly is connected to the second conveyor roller 307. The first transmission assembly is a first drive motor, which is installed at the end of the second conveyor roller 307. The first transmission assembly is detachably connected to the first conveyor roller 208 via the clutch assembly 308. The first transmission assembly can drive the first conveyor roller 208 and the second conveyor roller 307 to run simultaneously. The clutch assembly 308 includes a clutch bracket 30801, a base plate 30803 fixed to the clutch bracket 30801 by a spring assembly 30802, a bearing seat 30804 mounted on the base plate 30803, a splined shaft 30805 mounted on the bearing seat 30804, a clutch sprocket 30806 mounted on the splined shaft 30805, and a helical gear clutch 30807 fixed on the sprocket. The helical gear clutch can be quickly disassembled, allowing the first transmission components of the first conveyor roller 208 and the second conveyor roller 307 to be quickly connected or separated, facilitating disassembly and maintenance.

[0073] like Figure 8As shown, the third buffer device 4 includes a third conveyor roller 401, a first material distribution mechanism 403, a second material distribution mechanism 402, and a third hopper 406. A second transmission assembly 405 is installed on the third conveyor roller 401, preferably a second transmission motor 404, to provide power to the third conveyor roller 401. The first end of the third conveyor roller 401 is connected to the second conveyor roller 307 of the second buffer device 3. Both the first material distribution mechanism 403 and the second material distribution mechanism 402 are disposed on the third conveyor roller 401. The third hopper 406 is disposed on the first side of the third conveyor roller 401, and the fourth buffer device 5 is disposed on the second side of the third conveyor roller 401. The first side and the second side of the third conveyor roller 401 are a pair of opposing sides. The first material sorting mechanism 403 is used to flip the pipes on the third conveyor roller 401 to the third hopper 406 for storage, and the second material sorting mechanism 402 is used to flip the pipes on the third conveyor roller 401 to the fourth buffer device 5 for buffering, thereby realizing material storage and sorting.

[0074] like Figure 9 As shown, the first material distribution mechanism 403 and the second material distribution mechanism 402 have the same structure, only differing in installation position. Both include a rotating shaft 40201, a third drive assembly 40203, and multiple material distribution plates 40202. The third drive assembly 40203 is preferably a cylinder. Taking the second material distribution assembly as an example, it includes a rotating shaft 40201, which is rotatably mounted on the third conveyor roller 401. Multiple material distribution plates 40202 are spaced apart on the rotating shaft 40201. A connecting rod 40204 is connected to the lower end of each material distribution plate 40202. A synchronous bracket 40205 is connected to the other end of the connecting rod 40204. A cylinder connector 40206 is mounted on the synchronous bracket 40205 and is connected to the third drive assembly 40203. Working principle: The third drive component 40203 extends and drives the synchronous bracket 40205 to move upward. The material distribution plate 40202 will rotate around the rotating shaft 40201, causing the pipe to flip to one side. The rotating shafts 40201 of the first material distribution mechanism 403 and the second material distribution mechanism 402 are symmetrically arranged on the left and right sides of the third conveyor roller 401 to realize the left and right flipping of the pipe.

[0075] like Figure 10As shown, the fourth buffer device 5 includes a fourth buffer frame 501, a buffer mechanism 504, and a feeding mechanism 502. The fourth buffer frame 501 has a triangular cross-section with a horizontal base. The buffer mechanism 504 includes a buffer rack 505 and a fourth drive assembly. The buffer rack 505 is hinged to the first inclined surface of the fourth buffer frame 501, with the hinge axis located at the apex of the fourth buffer frame 501. The fourth drive assembly, preferably a cylinder, is mounted on the fourth buffer frame 501. The fourth drive assembly is connected to the buffer rack 505 to drive the buffer rack 505 to rotate between a horizontal and an inclined state. When the buffer rack 505 is full, the cylinder extends, and the buffer rack 505 rotates to be horizontal with the ground, facilitating material removal by subsequent palletizing equipment.

[0076] like Figure 11 As shown, the feeding mechanism 502 includes a fifth drive assembly 50201 and multiple feeding chains 50202. The fifth drive assembly 50201 is preferably a motor. The multiple feeding chains 50202 are arranged sequentially and at intervals along the conveying direction of the third conveyor roller conveyor 401. Multiple stops 50203 are spaced apart on each feeding chain 50202. All feeding chains 50202 are connected to the fifth drive assembly 50201, which drives them to rotate. One end of each feeding chain 50202 is connected to the second side of the third conveyor roller conveyor 401, and the second material distribution mechanism 402 is used to flip the pipes on the third conveyor roller conveyor 401 onto the feeding chain 50202. The other end of each feeding chain 50202 is coaxially arranged with a buffer rack 505, and the feeding chain 50202 is used to transport the pipes onto the buffer rack 505. After being flipped by the second material distribution mechanism 402, the pipe falls onto the feeding chain 50202 of the feeding mechanism 502. The pipe slides down the feeding chain 50202 by the stop block 50203. The fifth drive component 50201 provides power to drive the feeding chain 50202 to rotate. The stop block 50203 on the feeding chain 50202 drives the pipe onto the buffer mechanism 504.

[0077] like Figure 12As shown, the fourth buffer device 5 also includes a height limiting mechanism 503, which includes a height limiting frame 50303, an adjusting component, and a lifting cylinder 50304. The height limiting frame 50303 is mounted on the buffer frame 505 via the adjusting component. The height limiting frame 50303 is located at the junction of the buffer frame 505 and the feeding chain 50202, and is used to control the diameter or height of the pipe entering the buffer mechanism 504. The height limiting frame 50303 is parallel to the buffer frame 505. The distance between the height limiting frame 50303 and the buffer frame 505 is adjusted by the adjusting component, thereby adjusting the diameter or height of the pipe entering the buffer mechanism 504. The lifting cylinder 50304 is mounted on the height limiting frame 50303 and is used to drive the pipe located below the height limiting frame 50303 to rotate so that the long side of the rectangular pipe abuts against the buffer frame 505. Specifically, the handwheel 50301 is manually adjusted according to the pipe specifications, the screw jack 50302 rotates, and the height limit frame 50303 descends, ensuring that the distance between the height limit frame 50303 and the buffer frame 505 is just enough to accommodate one pipe, preventing changes in the posture of the rectangular pipe during its descent. When the lifting cylinder 50304 on the height limit frame 50303 extends, it pushes the rectangular pipe to rotate, ensuring that the long side of the rectangular pipe rests against the buffer frame 505. The pipe slides down through the buffer frame 505 into the buffer area. When the buffer area is full, the baffle column 506 rises, and 2-3 pipes can be buffered at the ramp. In addition, the feeding chain 50202 of the feeding mechanism 502 can buffer 4 pipes. After the buffer area is full, when the buffer frame 505 is full, the cylinder extends, and the buffer frame 505 rotates to be horizontal with the ground, facilitating subsequent material removal by the palletizing equipment.
