Driving the tensioning motor to work can drive the tensioning wheel to rotate. At this time, the tensioning wheel winds up the flexible support belt and drives the bottom end of the flexible support belt to move upward, so that the flexible support belt is in a tensioned state.

[0006] Further, the tensioning device further includes a fulcrum wheel. The fulcrum wheel is rotatably arranged on the top end of the right side of the aggregate frame.

At this time, the driving rod drives the blanking plate to rotate through the connecting rod, so that the blanking plate is in a vertical state relative to the material conveying seat.

[0013] Further, a plurality of material guiding mechanisms are provided between the aggregate frame and the blanking device.

[0014] Further, a mounting seat is provided on the material conveying seat, and a sensor is provided on the mounting seat.

[0015] The prominent and beneficial technical effects of the present invention compared with the prior art are:

[0016] The present invention belongs to the technical field of mechanical equipment, and particularly refers to an automatic profile feeding and sorting device, which includes a feeding base and an aggregate frame arranged on one side of the feeding base. A conveying device for conveying materials and a feeding device for pushing the materials on the feeding base into the aggregate frame are provided on the feeding base. In an automated profile production line, after the upstream sawing production line saws the raw materials into finished products, they will be conveyed onto the feeding base. At this time, the conveying device starts to work, conveys the materials to one side of the aggregate frame and then stops working. Since an aggregate space is formed in the aggregate frame, a flexible support belt is provided in the aggregate space. The tensioning device on the aggregate frame consists of a tensioning wheel and a tensioning motor for driving the tensioning wheel to rotate. One end of the flexible support belt is connected to the left side of the aggregate frame, and the other end of the flexible support belt is fixedly connected to the tensioning wheel. At this time, the flexible support belt is in a "U" shape. Compared with the existing manual feeding and sorting methods for profile materials, not only does it greatly increase the labor cost, the feeding efficiency is extremely low, it does not have functions such as high efficiency and automation, but also when feeding into the material frame for collecting profiles, there is a large noise and it is easy to damage the workpieces. In the present invention, when the tensioning motor works, it can drive the tensioning wheel to rotate. The tensioning wheel will wind up the flexible support belt and drive the bottom end of the flexible support belt to move upward, making the flexible support belt in a tensioned state. At this time, the distance between the flexible support belt and the ground increases, and conversely, the distance between the flexible support belt and the materials on the aggregate frame decreases. When the feeding device pushes the materials into the aggregate space of the aggregate frame, the materials will fall onto the flexible support belt, thereby restricting the materials from directly falling into the aggregate frame. Moreover, the present invention can sort single round bars with a diameter within 180 mm into the feeding frame. This method of single-piece feeding and sorting materials greatly improves the feeding efficiency, realizes full automation, eliminates the need for manual feeding and sorting, reduces the labor cost expenditure, and reduces the noise and material damage generated by the falling of materials through the tensioning and contraction of the flexible support belt.

[0039] The present invention will be further described below in conjunction with specific embodiments:

[0040] The present invention belongs to the technical field of mechanical equipment, and particularly refers to an automatic profile feeding and sorting device, which includes a feeding base 1 and an aggregate frame 2 arranged on one side of the feeding base 1. A conveying device for conveying materials and a blanking device for pushing the materials on the feeding base 1 into the aggregate frame 2 are provided on the feeding base 1. In the automatic profile blanking production line, after the upstream sawing production line saws the raw materials into finished products, they will be conveyed to the feeding base 1. At this time, the conveying device starts to work and conveys the materials to one side of the aggregate frame 2 and then stops working. Since an aggregate space 5 is formed in the aggregate frame 2, a flexible support belt 6 is arranged in the aggregate space 5. The tensioning device on the aggregate frame 2 consists of a tensioning wheel 8 and a tensioning motor 9 for driving the tensioning wheel 8 to rotate. One end of the flexible support belt 6 is connected to the left side of the aggregate frame 2, and the other end of the flexible support belt 6 is fixedly connected to the tensioning wheel 8. At this time, the flexible support belt 6 is in a "U" shape. Compared with the existing profile material blanking method, which is all manual blanking and sorting, it not only greatly increases the labor cost, but also has extremely low blanking efficiency, and does not have functions such as high efficiency and automation. Moreover, when blanking into the material frame for collecting profiles, there is a lot of noise and it is easy to damage the workpieces. In the present invention, when the tensioning motor 9 works, it can drive the tensioning wheel 8 to rotate. The tensioning wheel 8 will wind up the flexible support belt 6 and drive the bottom end of the flexible support belt 6 to move upward, so that the flexible support belt 6 is in a tensioned state. At this time, the distance between the flexible support belt 6 and the ground increases, and conversely, the distance between the flexible support belt 6 and the materials on the aggregate frame 2 decreases. When the blanking device pushes the materials into the aggregate space 5 of the aggregate frame 2, the materials will fall onto the flexible support belt 6, thereby restricting the materials from directly falling into the aggregate frame 2. Moreover, the present invention can sort single round bars with a diameter within 180 mm into the blanking frame. This method of single-piece blanking and sorting materials greatly improves the blanking efficiency, realizes full automation, eliminates the need for manual blanking and sorting, reduces the labor cost expenditure, and reduces the noise and material damage generated by the falling of materials through the tensioning and contraction of the flexible support belt 6.

[0041] Preferably, the tensioning device further includes a fulcrum wheel 10 which is rotatably arranged on the top end of the right side of the aggregate frame 2. The other end of the flexible support belt 6 bypasses the movable wheel and is fixedly connected to the tensioning wheel 8. One end of the flexible support belt 6 is fixedly connected to the top end of the left side of the aggregate frame 2. An installation wheel 11 is rotatably arranged on the top end of the left side of the aggregate frame 2. One end of the flexible support belt 6 is formed with an installation sleeve 12, and the installation sleeve 12 is sleeved on the installation wheel 11. Since the installation wheel 11 and the fulcrum wheel 10 are respectively located on the top ends of the left and right sides of the aggregate frame 2, and one end of the flexible support belt 6 is sleeved on the installation wheel 11 through the installation sleeve 12, the connection between one end of the flexible support belt 6 and the installation wheel 11 is more stable and firm, so that one end of the flexible support belt 6 will not be separated from the installation wheel 11. When the tensioning wheel 8 winds up the flexible support belt 6, after the flexible support belt 6 is tightened, the flexible support belt 6 will be in a horizontal state in the aggregate frame 2 at this time, so that the flexible support belt 6 is closer to the materials on the material conveying seat 1.

[0042] Preferably, the tensioning device further includes a reduction gearbox 13 connected to the motor shaft of the tensioning motor 9 and a linkage shaft 14. A reduction mechanism is arranged in the reduction gearbox 13. One end of the linkage shaft 14 is located in the reduction gearbox 13 and is connected to the reduction mechanism. The number of the aggregate frames 2 is multiple, and a tensioning wheel 8 is arranged on each aggregate frame 2. The tensioning wheels 8 are all connected to a linkage rod. When the tensioning motor 9 works, the motor shaft on the tensioning motor 9 will rotate at this time. After the motor shaft rotates, it will drive the reduction mechanism in the reduction gearbox 13 to work. After the reduction mechanism works, it will drive the linkage shaft 14 to rotate. Since the number of the aggregate frames 2 is multiple, materials with different lengths can be sorted into the aggregate frames 2, and the materials sorted into the aggregate frames 2 can be horizontally stored on the flexible support belt 6, and will not slide down obliquely from the aggregate frames 2 due to the small number of the aggregate frames 2. The flexible support belt 6 of the present invention can carry more materials and has a material storage function. In fact, it can carry different specifications of materials with a weight of 5T and a length of 1500mm - 7000mm, and has stronger practicability. Since the tensioning wheels 8 on each aggregate frame 2 are all connected to the linkage rod, when the linkage rod rotates, the tensioning wheels 8 on the linkage rod will rotate synchronously, so that the flexible support belts 6 in each aggregate frame 2 can be tightened by the tensioning wheels 8 at the same time.

[0043] Preferably, an encoder 15 is provided on the linkage rod. Since the encoder 15 provided on the linkage rod is common in the market and is widely used in fields such as motor control and numerical control machine tools, when the tensioning motor 9 drives the linkage rod to rotate through the tensioning wheel 8, the encoder 15 on the linkage rod will rotate synchronously with the linkage rod. Thus, when the encoder 15 rotates to a certain angle, the encoder 15 will control the tensioning motor 9 to stop working. At this time, when the flexible support belt 6 is just in a tensioned state, it can prevent the flexible support belt 6 from being too tight or too loose, which may cause damage to the flexible support belt 6 and the workpiece. When the flexible support belt 6 is in a tensioned state, after the material falls onto the flexible support belt 6, due to the weight of the material, the central area of the flexible support belt 6 will move downward by a certain distance. At this time, the flexible support belt 6 will drive the tensioning wheel 8 to rotate by a certain angle, and the tensioning wheel 8 will drive the linkage rod to rotate by a certain angle. At this time, the encoder 15 on the linkage rod will rotate synchronously. At this time, the rotation angle of the encoder 15 is the rotation angle of the tensioning wheel 8. When the rotation angle of the encoder 15 reaches the initially set value, it means that the material on the flexible support belt 6 has reached the specified quantity. At this time, the encoder 15 controls the tensioning motor 9 to drive the tensioning wheel 8 to rotate in the reverse direction. With the weight of the material on the flexible support belt 6 itself, the flexible support belt 6 will slowly loosen, so that the material accumulates at the bottom inside the aggregate frame 2. During this process, the material will not fall instantaneously, avoiding the occurrence of material damage.

[0044] Preferably, the conveying device includes a plurality of roller assemblies 3. Each roller assembly 3 includes a roller 16 rotatably provided on the material conveying base 1 and a driving motor 17 connected to the roller 16. Driving the driving motor 17 to work can drive the roller 16 to rotate;

[0045] The conveying device is a common roller assembly 3 in the market. When the upstream sawing production line saws the raw material into finished products and conveys them to the material conveying base 1, the material is located on the upper surface of the roller 16. At this time, after the driving motor 17 starts to work, it will drive the roller 16 to rotate, and the material is smoothly conveyed to one side of the aggregate frame 2 through the rotation of the roller 16. This conveying method through the roller 16 makes the material run stably and reliably and the conveying is smooth.

[0046] Preferably, a plurality of mounting brackets 18 for mounting the roller 16 are provided on the material feeding base 1. Each mounting bracket 18 includes a left mounting plate 19 and a right mounting plate 20 which are symmetrically arranged. The roller 16 is located between the left mounting plate 19 and the right mounting plate 20. Rotating shafts 21 are provided at both ends of the roller 16. Rotation holes 22 are formed in both the left mounting plate 19 and the right mounting plate 20. The rotating shafts 21 at both ends of the roller 16 are respectively rotatably arranged in the rotation holes 22 of the left mounting plate 19 and the rotation holes 22 of the right mounting plate 20, and bearings 23 are provided in the rotation holes 22. The bearings 23 are sleeved on the rotating shafts 21. The roller 16 is rotatably mounted on the mounting bracket 18 on the material feeding base 1 by rotatably arranging the rotating shaft 21 at one end in the rotation hole 22 of the left mounting plate 19 and the rotating shaft 21 at the other end of the roller 16 in the rotation hole 22 of the right mounting plate 20. The bearing 23 in the rotation hole 22 is sleeved on the rotating shaft 21, so that the rotating shaft 21 cannot directly contact the inner wall of the rotation hole 22. When the rotating shaft 21 rotates, friction can be reduced, and the rotating shaft 21 will not be severely worn after long-term use, greatly increasing the service life of the rotating shaft 21.

[0047] Preferably, the blanking device includes a plurality of blanking plates 24 rotatably arranged on the material conveying base 1. An inclined surface 25 is formed at the top end of the blanking plate 24. A driving air cylinder 26 for driving the blanking plate 24 to rotate is provided on the material conveying base 1. A piston rod 27 is provided on the driving air cylinder 26. A connecting seat 28 is connected to the piston rod 27. A driving rod 29 is connected to the connecting seat 28. A connecting rod 30 is provided between the driving rod 29 and the blanking plate 24. The bottom end of the connecting rod 30 is rotatably connected to the driving rod 29, and the top end of the connecting rod 30 is fixedly connected to the blanking plate 24. Driving the piston rod 27 to extend can drive the driving rod 29 to move horizontally through the connecting seat 28. At this time, the driving rod 29 drives the blanking plate 24 to rotate through the connecting rod 30, so that the blanking plate 24 is in a vertical state relative to the material conveying base 1. The blanking device is composed of a plurality of blanking plates 24 rotatably arranged on the material conveying base 1. When the driving air cylinder 26 controls the piston rod 27 to extend, it will drive the connecting seat 28 to move horizontally. Since the driving rod 29 is connected to the connecting seat 28, the connecting seat 28 will drive the driving rod 29 to move horizontally synchronously. The bottom end of the connecting rod 30 between the driving rod 29 and the blanking plate 24 is rotatably connected to the driving rod 29, and the top end of the connecting rod 30 is fixedly connected to the blanking plate 24. Therefore, when the driving rod 29 moves horizontally, it will drive the blanking plate 24 to turn upward through the connecting rod 30, so that the blanking plate 24 is in a vertical state relative to the material conveying base 1. At this time, the blanking plate 24 will lift the material located on the material conveying base 1, so that the material is located at the top end of the blanking plate 24. And because the top end of the blanking plate 24 is formed with an inclined surface 25, the material can fall into the aggregate frame 2 along the inclined surface 25, thus completing the work of sorting the material into the aggregate frame 2 one by one. There is no need for workers to manually blank and sort. This automated method improves the efficiency of blanking and sorting. And when the material is a round bar, at this time, the round bar will roll to the aggregate frame 2 along the inclined surface 25 at the top end of the blanking plate 24, so that the material descends slowly, reducing noise.

[0048] Preferably, a plurality of material guiding mechanisms 31 are provided between the aggregate frame 2 and the blanking device. The material guiding mechanism 31 includes a first material guiding plate 32 and a second material guiding plate 33. The tops of the first material guiding plate 32 and the second material guiding plate 33 are both formed with inclined surfaces 25. The first material guiding plate 32 is fixedly arranged on the material conveying seat 1, and the second material guiding plate 33 is fixedly arranged on the top of the aggregate frame 2. When the blanking plate 24 is perpendicular to the material conveying seat 1, the material will first slide onto the first material guiding plate 32 along the inclined surface 25 at the top of the blanking plate 24. Since the top of the first guiding plate is formed with an inclined surface 25, the material on the first material guiding plate 32 will slide onto the second material guiding plate 33 along the inclined surface 25. And since the top of the second material guiding plate 33 is also formed with an inclined surface 25, and the second material guiding plate 33 is fixedly arranged on the top of the aggregate frame 2, the material at the top of the second material guiding plate 33 will move onto the flexible support belt 6 of the aggregate frame 2 along the inclined surface 25 at the top of the second material guiding plate 33. Since there is a certain distance between the aggregate frame 2 and the material conveying seat 1 of the present invention, the arrangement of the first material guiding plate 32 and the second material guiding plate 33 enables the material to smoothly enter the aggregate frame 2 through the first material guiding plate 32 and the second material guiding plate 33, so that the material will not fall to the ground from the gap between the aggregate frame 2 and the material conveying seat 1, thus affecting the normal sorting of the material.

[0049] Preferably, an installation seat 35 is provided on the material conveying seat 1, and a sensor 36 is provided on the installation seat 35. The sensor 36 is common in the market, such as a vision sensor 36, a laser sensor 36, an infrared sensor 36, etc. The sensor 36 of the present invention mainly detects the position of one end of the material. When one end of the material moves to the specified position, the sensor 36 will control the driving motor 17 to stop working, so that the roller 16 stops conveying the material. This way can ensure that one end of each subsequent material can be aligned. Thus, after the blanking mechanism sorts the material into the aggregate frame 2, the distances between the ends of the materials are not very far apart, which is convenient for workers to lift the materials subsequently.

[0050] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
