[0002] Laser tube cutting machine is a kind of efficient and precise metal tube processing equipment. It uses high-energy laser beam to cut metal tubes. It has the characteristics of fast cutting speed, high precision, strong material adaptability and easy operation. The path of laser beam is accurately controlled by computer numerical control system to achieve rapid melting and evaporation cutting of metal tubes. It is suitable for a variety of metal materials.

[0003] In order to achieve continuous production and improve the degree of automation, laser tube cutting machines are usually equipped with a material handling system and a finished product warehouse to stack and store the cut tubes.

[0004] In the finished product warehouse, pipes are stacked up and down. When the cross-section of the pipe is an unequal-sided rectangle, the pipe cutting machine usually rolls over when cutting the pipe, resulting in two placement postures: one with the long side as the bottom and the other with the short side as the bottom. After the handling system transports the pipes to the warehouse, the long side of the pipes will be stacked on the short side. As more and more pipes are stacked, the stacked pipes are prone to collapse, the stacking is messy, and the pipes collide with each other, causing damage to the pipes. Summary of the invention

[0027] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] Embodiment 1 like Figure 1 As shown, a pipe sorting and stacking system comprises: The material receiving unit 100 includes a first pipe channel and a first pipe conveying mechanism. The first pipe conveying mechanism is used to drive the pipe to move along the first pipe channel. The first pipe channel is provided with a pipe identification and detection mechanism 110. Specifically, Figure 2 , 3 As shown, the receiving unit 100 includes a receiving unit frame, a receiving hopper 101 is installed on the receiving unit frame, the bottom of the receiving hopper 101 includes two first inclined surfaces and a second inclined surface perpendicular to each other, the first pipe channel is formed between the first inclined surface and the second inclined surface, the first pipe conveying mechanism is arranged on one side of the receiving hopper 101, the first pipe conveying mechanism includes a first linear guide rail 103 installed on the receiving unit frame, and a pusher frame 102 is movably arranged on the first linear guide rail 103, as shown in FIG. Figure 3 As shown, the pusher rack 102 is door-shaped, and one end of the pusher rack 102 extends into the lower part of the V-shaped receiving hopper 101. The receiving unit frame is also provided with a first drive motor 105 and a synchronous belt 104. The first drive motor 105 drives the synchronous belt 104 to move, and the pusher rack 102 is connected to the straight section of the synchronous belt 104. Then, the synchronous belt 104 can drive the pusher rack 102 to move. Along the pipe conveying direction, the detection mechanism 110 is arranged at the rear end of the receiving hopper 101 (conveying from front to back), and the detection mechanism 110 includes a first adjustment module 111 and a second adjustment module 113, a first sensor 112 and a second sensor 114, the first adjustment module 111 is installed on the outer side of the first inclined surface and can move along the inclination direction of the first inclined surface, and the first sensor 112 is installed on the first adjustment module 111; the second adjustment module 113 is installed on the outer side of the second inclined surface and can move along the inclination direction of the second inclined surface, and the second sensor 114 is installed on the second adjustment module 113, the detection direction of the first sensor 112 is perpendicular to the first inclined surface and toward the inside of the receiving hopper 101, and the detection direction of the second sensor 114 is perpendicular to the second inclined surface and toward the inside of the receiving hopper 101.

[0029] The working process of the material receiving unit 100 is as follows: Figure 1 , 2 As shown, the unloading mechanism of the pipe cutting machine is arranged on the other side of the receiving hopper 101 relative to the pushing frame 102, and the cut pipe slides into the receiving hopper 101 along the inclined surface of the unloading mechanism, and a group of adjacent surfaces of the pipe (square pipe) are respectively abutted against the two inclined surfaces of the receiving hopper 101, and then, the first driving motor drives the pushing frame to move backward, and the pushing frame is located at one end in the receiving hopper to push the front end of the pipe. When the pipe passes through the detection mechanism, the first sensor and the second sensor detect the position of the long side and the short side of the pipe. For example, the first sensor and the second sensor adopt laser displacement sensors, and by adjusting the position of the first adjustment module and the second adjustment module, the first adjustment module and the second adjustment module can adopt the form of a slider and a locking screw, so that the two sensors are located at a distance from the bottom of the receiving hopper that is greater than the short side of the pipe and less than the long side of the pipe. When the pipe passes, the detection direction of one of the sensors is blocked by the long side, and the position of the long side of the pipe is obtained at this time.

[0030] The sorting unit 200, such as Figure 4 As shown, the sorting unit 200 includes a sorting unit frame, a sorting mechanism is provided in the middle of the sorting unit frame, and along the pipe conveying direction, the sorting mechanism is opposite to the first pipe channel, and the sorting mechanism includes a sorting bucket 201, and the sorting bucket 201 includes a V-shaped receiving groove opening upward, and the front and rear ends of the sorting unit frame are respectively provided with seat bearings 203, and the bottom of the sorting bucket 201 is provided with a rotating shaft, and the rotating shaft is set along the pipe conveying direction, and the two ends of the rotating shaft are installed in the seat bearings 203. A second driving motor 205 is also provided on the sorting unit frame, and the second driving motor 205 drives the rotating shaft to rotate through a transmission chain 204. A second pipe conveying mechanism and a third pipe conveying mechanism are respectively provided on both sides of the material distribution mechanism. The second pipe conveying mechanism and the third pipe conveying mechanism are arranged side by side in a direction perpendicular to the pipe conveying. When the material distribution bucket 201 flips to both sides, its opening faces the second pipe conveying mechanism and the third pipe conveying mechanism respectively. The second pipe conveying mechanism and the third pipe conveying mechanism are both in the form of rollers, and respectively include multiple electric rollers 202. One end of the electric roller 202 is close to the rotating shaft of the material distribution bucket 201, and an avoidance groove is opened on the side wall of the material distribution bucket corresponding to the position of the electric roller.

[0031] like Figure 1As shown, the material distribution bucket is connected to the receiving hopper, and in the initial position, the V-shaped channel of the material distribution mechanism overlaps with the V-shaped channel of the receiving hopper (i.e., the first pipe channel) in the pipe conveying direction. When the pushing rack pushes the pipe to the end of the receiving hopper, the pipe just enters the material distribution bucket. At this time, the relative position of the long side and the short side of the pipe is obtained by the detection mechanism, and the second drive motor drives the material distribution bucket to flip to one side, so that the side wall of the material distribution bucket sinks to the bottom of the electric roller on that side. At this time, the pipe is placed on the electric roller, and the electric roller starts to convey the pipe backward. After the pipe leaves, the material distribution bucket resets.

[0032] Aggregate unit 300, such as Figure 5 , 6 As shown, it includes a first material waiting area 304 and a second material waiting area 305, the first material waiting area 304 and the second material waiting area 305 are arranged side by side along a direction perpendicular to the pipe conveying, a temporary storage area is provided between the first material waiting area 304 and the second material waiting area 305, and a pushing device is provided above the temporary storage area, the pushing device includes a first pushing device and a second pushing device, the first pushing device is directed toward the first material waiting area, and the second pushing device is directed toward the second material waiting area, the first pushing device and the second pushing device respectively include a plurality of pushing mechanisms 310, and the pushing mechanisms 310 in the first pushing device and the second pushing device are arranged at intervals, as shown in FIG. Figure 6 As shown, the pushing mechanism 310 includes a linear module 311, and the linear module 311 can adopt a linear driving structure such as a lead screw. A mounting plate is provided on the moving part of the linear module 311, and a slide plate 313 is installed on the mounting plate through a second linear guide rail 314. A pushing plate 315 is installed on the slide plate 313 through a guide rod. The pushing plate 315 is located at the lower part of the slide plate 313, and a spring and a detection switch 316 are provided between the pushing plate 315 and the slide plate 313. The mounting plate is also provided with a lifting cylinder 312, the cylinder rod of the lifting cylinder 312 is connected to the slide plate 313, and the moving part of the linear module 311 is provided with a pushing plate 315; the first pushing device and the second pushing device are also respectively provided with a transmission shaft 302, and the transmission shaft 302 is connected to the third driving motor 301, and the transmission shaft 302 synchronously drives the corresponding multiple linear modules 311. For example, the linear module adopts a lead screw form, and mutually meshing bevel gear pairs are arranged on the end of the lead screw and the transmission shaft 302 to complete synchronous transmission.

[0033] The material collection unit is connected to the sorting unit. The aforementioned electric roller transports the pipe to the temporary storage area of ​​the material collection unit. At the same time, the pipe is placed on one side in the sorting unit, so in the temporary storage area, the pipe is also placed on one side. At this time, the relative position of the long side and the short side of the pipe obtained by the detection mechanism is used to determine the placement position of the pipe in the temporary storage area. The first pusher device or the second pusher device is activated according to the deviation of the pipe to push the pipe into the first temporary storage area or the second temporary storage area. During the pushing process, the lifting cylinder 312 extends and drives the slide plate to descend, so that the pusher plate is located on one side of the pipe. Then the third drive motor is activated, and the slide plate and the pusher plate push the pipe to move. When the pipe is pushed into the temporary storage area, it conflicts with the end limit of the temporary storage area or other existing pipes and cannot continue to move. At this time, the spring is compressed, and the pusher plate triggers the detection switch, indicating that the pipe has been stacked in place and the pusher device is reset.

[0034] like Figure 1 , 6 As shown, the pipe sorting and stacking system also includes a stacking unit 400, which includes a first material warehouse 404, a second material warehouse 405 and a handling device. The first material warehouse 404 and the second material warehouse 405 are respectively arranged on both sides of the first temporary storage area and the second temporary storage area in the aggregate unit 300, and the handling device includes a beam assembly 401, which spans above the first material warehouse 404, the second material warehouse 405, the first waiting area 304 and the second waiting area 305. A Z-axis assembly 402 is provided on the beam assembly, and the Z-axis assembly 402 can move along the beam assembly. For example, a pulley structure is provided on the beam assembly, and the pulley structure is connected to the beam assembly through a gear rack, and the pulley is driven to move along the beam assembly through the gear rack structure. The Z-axis assembly is arranged on the pulley, and an electromagnet 403 is provided on the Z-axis assembly, which can transport the pipe from the first waiting area to the first material warehouse, or from the second waiting area to the second material warehouse.

[0035] Embodiment 2 A pipe sorting and stacking method, using the pipe sorting and stacking system described in Example 1, the method comprises the following steps: S1. The cut tube is placed into the first tube channel, and the first tube conveying mechanism pushes the tube toward the sorting unit 200; S2. When the pipe passes through the detection mechanism 110, the detection mechanism 110 identifies the shape of the pipe; S3. The pipe enters the material distribution mechanism, and the material distribution mechanism sends the pipe to the second pipe conveying mechanism or the third pipe conveying mechanism according to the pipe shape identified by the detection mechanism; S4. The second pipe conveying mechanism or the third pipe conveying mechanism conveys the pipe to the collecting unit 300; S5. The pushing device pushes the pipe to the first waiting area or the second waiting area according to the pipe shape identified by the detection mechanism 110.

[0036] Specifically, Figure 8 Taking the process shown as an example, first, the positions of two sensors are set according to the lengths of the long and short sides of the pipe, and then the pipe cut by the pipe cutting machine 500 falls into the receiving hopper 101, and the first driving motor drives the pushing rack to move and push the pipe backward. The long side of the pipe will cover the sensor on one side (side A or side B), and the relative positions of the long and short sides of the pipe can be determined at this time. As the pushing rack continues to push, the pipe enters the dividing bucket 201. At this time, the dividing bucket flips to the A side or the B side according to the position of the long and short sides of the pipe. For example, the pipe with the long side facing down is placed on the second pipe conveying mechanism, and the pipe with the short side facing down is placed on the third pipe conveying mechanism; then, the second pipe conveying mechanism or the third pipe conveying mechanism conveys the pipe to the collecting unit, and the pushing device pushes the pipe to the first waiting area or the second waiting area. Finally, the stacking unit transports the pipe to the corresponding material warehouse.

[0037] For equilateral pipes, there is no need to identify them and they can be directly sorted into the same material warehouse through this system. If the sensors on both sides are triggered when transporting unequal-sided pipes, the system will report an error and it is necessary to check whether there are other obstructions or readjust the sensor position.

[0038] It can be seen from the above implementation modes that the beneficial effect of the present invention is that the pipe sorting system provided by the present scheme can effectively improve the neatness of pipe stacking, avoid the problems of messy stacking and collapse caused by the up and down stacking of long and short sides, thereby improving the cleanliness and safety of the workplace, and through precise identification and sorting, significantly reducing the damage to pipes during transportation and stacking, ensuring product quality; the detection mechanism adopted by the system identifies in the directions of both sides of the profile, has high identification accuracy, and can be adaptively adjusted according to the different side lengths of the pipe, with strong adaptability and a wide range of applications; the material dividing bucket and roller conveyor mechanism ensure the stability of the pipe during the sorting process, and reduce rolling and slipping; the design of the pushing device and the stacking unit realizes the automatic sorting and stacking of pipes, improves production efficiency, optimizes the production process, and reduces labor costs.
