Description

Technical Field

[0001] This invention relates to the field of angle steel processing equipment, specifically an automatic angle steel feeding system. Background Technology

[0002] Angle steel is commonly used in the manufacture of angle steel towers. The process typically involves cutting the original angle steel to its length, chamfering corners, drilling holes, and printing, among other processing operations. Currently, the material preparation for angle steel production for towers still requires manual labor. After processing, the steel is flipped and cut into individual pieces using a flipping mechanism, and manual assistance is still needed to straighten them. This increases labor time and costs, increases labor intensity, reduces safety, and lowers material preparation efficiency, resulting in lower factory production efficiency.

[0003] In addition, traditional angle steel cutting equipment has some problems: angle steel production lines process a wide variety of parts, and manual cutting and sorting are time-consuming and can even affect the production cycle; angle steel production lines process a wide range of parts, and manual cutting of large parts poses safety hazards; the cutting, hole making, marking and other processes of angle steel production lines, as well as the angle steel itself, will bring rust, slag, dust and other harmful substances into the environment, which are harmful to human health.

[0004] In response to the current situation, a new automatic angle steel feeding device has been invented, which includes angle steel stacking and buffering mechanisms. It can feed materials in batches, reduce processes, speed up the production pace, save the time of manual material handling, reduce labor costs, and help improve the production efficiency and economic benefits of enterprises. Summary of the Invention

[0005] To address the existing problems, this invention provides an automatic angle steel feeding system with an angle steel stacking and buffering mechanism, which can feed materials in batches, reduce cycle time, eliminate the need for manual handling of individual materials, reduce labor costs, and improve production efficiency and economic benefits.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] As shown in the attached figure, the automatic angle steel feeding system provided by the present invention includes an automatic discharge channel, a stacking device, a receiving and conveying buffer device, and an electrical control system. The automatic discharge channel, the stacking device, and the receiving and conveying buffer device are sequentially and fixedly arranged adjacent to each other. The automatic discharge channel includes a discharge support, a roller group, and an electromagnet flipping mechanism. The roller group includes a first roller group, a second roller group, and a third roller group, which are sequentially and continuously arranged on the discharge support. The first roller group is driven by a discharge motor, the second roller group receives the material conveyed by the first roller group, and the third roller group is driven by a roller motor and synchronously drives the second sprocket group through a sprocket. An electromagnet flipping mechanism is installed below the first, second, and third roller groups. The electromagnet flipping mechanism flips the angle steel to the stacking device. The stacking device includes a stacking base, a stacking motor, a lifting frame, a positioning component, and a lifting screw. The lifting frame is installed on the stacking base and can move vertically on the stacking base. A positioning component is fixedly installed above the lifting frame to place the angle steel flipped by the electromagnet flipping mechanism. The receiving and conveying buffer device transfers or temporarily stores the multi-layer angle steel on the stacking device by setting a receiving rack. The power units in the automatic discharge channel, the stacking device, and the receiving and conveying buffer device are all electrically connected to the electrical control system.

[0008] In the aforementioned automatic angle steel feeding system, the discharge motor and roller motor are fixedly mounted on the discharge bracket. The output shaft of the discharge motor is connected to an electromagnetic clutch, which is connected to the rotating shaft of the first roller group. Multiple first roller groups are configured, and they rotate synchronously in conjunction with each other via a first sprocket drive group. Multiple second roller groups are configured, and they rotate synchronously in conjunction with each other via a second sprocket drive group. Multiple third roller groups are configured, and they rotate synchronously in conjunction with each other via a third sprocket drive group. An electromagnetic clutch is mounted on the third sprocket drive group. The first, second, and third sprocket drive groups all use a transmission connection method consisting of gears and sprockets.

[0009] The aforementioned automatic angle steel feeding system includes an electromagnet flipping mechanism comprising a flipping motor, a transmission box, a flipping coupling, and a flipping electromagnet. The flipping coupling is connected to the discharge bracket via bearings. The flipping coupling is connected to the output shaft of the flipping motor via the transmission box. The transmission box contains a transmission structure composed of gears and bevel gears. Both the transmission box and the flipping motor are fixed to the discharge bracket. A flipping electromagnet is mounted on the flipping coupling via an extended arm. The upper end of the flipping electromagnet is configured as a V-shaped receiving seat to receive angle steel located on the first roller group, the second roller group, and the third roller group.

[0010] The aforementioned automatic angle steel unloading system, including a stacking device, further comprises a coupling lifting transmission group for synchronous drive. This group includes a synchronous shaft with gears and bevel gears for synchronous transmission. A stacking motor is mounted on the stacking base, and the output shaft of the stacking motor drives the synchronous shaft to rotate via bevel gear transmission. At multiple points on the synchronous shaft, a lifting screw is also driven to rotate via bevel gear transmission. The stacking base is equipped with guide columns, and the lifting frame is equipped with guide holes. When the lifting screw rotates, the lifting frame causes the positioning component to move vertically under the guidance of the guide holes and guide columns, thus lifting the positioning component. The positioning component has an end face conforming to the angle steel structure.

[0011] The aforementioned automatic angle steel unloading system further includes a receiving and conveying buffer device comprising a conveying bracket, a conveying motor, and a cam transmission frame. The conveying motor is mounted on the conveying bracket, and the output shaft of the conveying motor is connected to the cam transmission frame. A gear transmission motor is also mounted on the conveying bracket, and a transmission gear is mounted on the connecting shaft of the output shaft of the gear transmission motor. A transmission rack meshing with the gear transmission motor is mounted on the receiving frame. The receiving frame and the cam transmission frame are connected by a guide rail and a slider, which drives the gear transmission motor to move the receiving frame laterally along the cam transmission frame under the guidance of the guide rail and the slider. The receiving frame is positioned below the positioning component of the stacking device.

[0012] The aforementioned automatic angle steel feeding system comprises an electrical control system consisting of a laser sensor, an electrical cabinet assembly, a servo control system, and a PLC control system.

[0013] The beneficial effects of this invention are:

[0014] The angle steel cutting system described in this invention is fully automatically controlled by an electrical control system; the cutting process is fully CNC-controlled and automatic, simple to operate, and can adapt to the cutting rhythm according to production needs, saving time and labor, improving work efficiency, and reducing costs; the cutting system is suitable for angle steel of sizes 63-160; it adopts parametric programming, which is simple to learn and workers can quickly master; it has a high degree of automation, one-button start, and automatically completes the entire cutting process, reducing the labor intensity of workers and improving the working environment; it has a simple structure, stable movement, and high reliability, greatly improving the production efficiency of enterprises.

[0015] Furthermore, the equipment employs a flip-type sorting and unloading system, a lifting frame for cumulative stacking, and a batch unloading system for material stacking. The receiving and conveying buffer device completes the unloading of large quantities of angle steel, reducing the number of unloading actions and time. The electromagnet flipping mechanism uses chain drive and V-type roller conveyor in conjunction with an electromagnetic clutch, resulting in low cost, effective positioning, stable material conveying, and high responsiveness. The electromagnet flipping mechanism is equipped with a laser sensor to accurately sense the presence and length of the material. A V-type electromagnet precisely grips the angle steel material, and a servo motor controls the flipping to a precise position. The flipping electromagnet and roller layout is compatible with angle steel materials of various lengths and specifications. The stacking device uses a servo motor to precisely match the descent distance according to different specifications of angle steel. The conveying section uses a gear rack and pinion system with a guide rail slider. The guide rail is mounted on a cam drive frame, increasing the rigidity of the cam drive frame. The buffer device uses a cam-progressive structure, which is simple in structure, smooth in movement, and highly reliable. The receiving and conveying buffer device is controlled by a servo motor, ensuring high control accuracy and smooth movement. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029]

Example 1

[0030] As shown in the attached figures, the present invention provides an automatic angle steel feeding system, comprising an automatic discharge channel 1, a stacking device 2, a receiving and conveying buffer device 3, and an electrical control system. The automatic discharge channel 1, the stacking device 2, and the receiving and conveying buffer device 3 are sequentially and fixedly arranged adjacent to each other. The automatic discharge channel 1 includes a discharge support 7, a roller group, and an electromagnet flipping mechanism 8. The roller group includes a first roller group 6, a second roller group 5, and a third roller group 25. Figure 2As shown, the automatic discharge channel 1 is divided into three working areas. The first roller group 6 corresponds to area A, with a roller spacing of 240mm. This area can be used for cutting angle steel of 500mm-1500mm. The second roller group 5 corresponds to area B, with a roller spacing of 500mm. This area can be used for cutting angle steel of 1000mm-2000mm. The third roller group 25 corresponds to area C, with a roller spacing of 1000mm. This area can be used for cutting angle steel of 1500mm-3000mm, accommodating the conveying of angle steel materials of various lengths. The first roller group 6 is driven by the discharge motor 12, the second roller group 5 receives the material conveyed by the first roller group 6, and the third roller group 25 is driven by the roller motor. The machine is driven by a sprocket and synchronously drives the second sprocket group. An electromagnet flipping mechanism 8 is set below the first roller group 6, the second roller group 5, and the third roller group 25. The electromagnet flipping mechanism 8 flips the angle steel to the stacking device 2. The stacking device 2 includes a stacking base 15, a stacking motor 17, a lifting frame 20, a positioning component 19, and a lifting screw 18. The lifting frame 20 is installed on the stacking base 15 and can move vertically on the stacking base 15. A positioning component 19 is fixedly set above the lifting frame 20 for placing the angle steel flipped by the electromagnet flipping mechanism 8. The receiving and conveying buffer device 3 transfers or temporarily stores the multi-layer angle steel on the stacking device 2 by setting a receiving rack 24. The power units in the automatic discharge channel 1, the stacking device 2, and the receiving and conveying buffer device 3 are all electrically connected to the electrical control system.

[0031] Furthermore, the discharge motor 12 and the roller motor are fixedly mounted on the discharge bracket 7. The output shaft of the discharge motor 12 is connected to an electromagnetic clutch 10, which is connected to the rotating shaft of the first roller group 6. The first roller group 6 has multiple sets, which rotate synchronously through the first sprocket transmission group 13. The second roller group 5 has multiple sets, which rotate synchronously through the second sprocket transmission group 9. The third roller group 25 has multiple sets, which rotate synchronously through the third sprocket transmission group. The third sprocket transmission group is equipped with an electromagnetic clutch 10. The first sprocket transmission group 13, the second sprocket transmission group 9, and the third sprocket transmission group are all connected by a transmission method consisting of gears and sprockets.

[0032] Furthermore, multiple sets of laser sensor switches are installed in areas A, B, and C on the automatic discharge channel 1, with each set evenly distributed in its respective area. A total of 26 laser sensor switches are installed on the entire automatic discharge channel 1.

[0033] Furthermore, the electromagnetic clutch 10 is provided with 3 sets. One set is installed and connected to the output shaft of the discharge motor 12, and the other two sets are set at the front end of area C. The design of the positions of the 3 sets of clutches meets the processing and cutting of angle steel of different lengths. When the angle steel is being cut, all 3 sets of clutches are disengaged to ensure that the material channel does not transmit angle steel.

[0034] Furthermore, the first roller group 6 is provided with 5 sets of rollers, each set of rollers including two rollers facing each other in a V shape, the second roller group 5 is provided with 6 sets of rollers, and the third roller group 25 is provided with 7 sets of rollers. Both the second roller group 5 and the third roller group 25 are provided with roller surfaces that conform to the shape of the angle steel.

[0035] Furthermore, the electromagnet flipping mechanism 8 includes a flipping motor 11, a transmission box 4, a flipping coupling 14, and a flipping electromagnet. The flipping coupling 14 is connected to the discharge bracket 7 via bearings. The flipping coupling 14 is connected to the output shaft of the flipping motor 11 via the transmission box 4. The transmission box 4 has a transmission structure composed of gears and bevel gears. Both the transmission box 4 and the flipping motor 11 are fixed on the discharge bracket 7. The flipping coupling 14 is provided with a flipping electromagnet via an extended arm. The upper end of the flipping electromagnet is provided with a V-shaped receiving seat to receive angle steel located on the first roller group 6, the second roller group 5, and the third roller group 25.

[0036] The automatic discharge channel 1 is mainly designed for angle steel of different specifications and lengths to stop when it is transported to a certain position on the roller group. The angle steel material is picked up by the flipping electromagnet of the electromagnet flipping mechanism 8, and the flipping motor 11 synchronously controls the flipping onto the stacking device 2. There are multiple sets of flipping electromagnets, which are distributed throughout the entire automatic discharge channel 1. They can flip angle steel materials of different lengths located at any position in the first roller group 6 and the second roller group 5.

[0037] Furthermore, the palletizing device 2 also includes a coupling lifting transmission group for synchronous drive, including a synchronous shaft 16 with gear and bevel gear linkage to achieve synchronous transmission. A palletizing motor 17 is installed on the palletizing base 15. The output shaft of the palletizing motor 17 drives the synchronous shaft 16 to rotate through bevel gear transmission. At multiple points on the synchronous shaft 16, the lifting screw 18 is also driven to rotate through bevel gear transmission. The palletizing base 15 is provided with guide columns, and the lifting frame 20 is provided with guide holes. When the lifting screw 18 rotates, the lifting frame 20 drives the positioning component 19 to move vertically under the guidance of the guide holes and guide columns, thereby realizing the lifting of the positioning component 19. The positioning component 19 has a structure with end face conforming to angle steel.

[0038] Furthermore, the receiving and conveying buffer device 3 also includes a conveying bracket 22, a conveying motor 21, and a cam transmission frame 23. The conveying motor 21 is mounted on the conveying bracket 22, and the output shaft of the conveying motor 21 is connected to the cam transmission frame 23. A gear transmission motor is also mounted on the conveying bracket 22, and a transmission gear is mounted on the connecting shaft of the output shaft of the gear transmission motor. A transmission rack meshing with the gear gear is mounted on the receiving frame 24. The receiving frame 24 and the cam transmission frame 23 are connected by a guide rail and a slider. The gear transmission motor drives the receiving frame 24, which in turn moves laterally along the cam transmission frame 23 under the guidance of the guide rail and the slider. The engagement of the transmission gear and the transmission rack, under the guidance of the guide rail and the slider, realizes the receiving action of the angle steel material. The receiving frame 24 is located below the positioning member 19 of the stacking device 2.

[0039] Furthermore, the cam drive frame 23 includes a cam and a top plate. The cam is mounted on the connecting shaft of the output shaft of the conveying motor 21. During one rotation of the cam, the top plate will move upward and backward once, and then return to its original position. As the cam continues to rotate, the regular upward-conveying-returning action will be repeated to realize the progressive movement of the cam drive frame 23 for conveying angle steel materials.

[0040] Furthermore, the electrical control system comprises a laser sensor, an electrical cabinet assembly, a servo control system, and a PLC control system. It employs parametric programming, making it simple to learn and quick for workers to get started.

[0041] Furthermore, the electromagnet flipping mechanism 8 has a fast flipping action, with a single flipping time controlled within 3 seconds, and the flipping motor 11 is equipped with a braking resistor that can effectively and quickly stop the flipping mechanism.

[0042] During the use of the equipment of this invention, before the angle steel is unloaded on the angle steel production line, the processed parts are arranged in a manner that follows the principle of long before short. Materials longer than 3 meters are given priority for arrangement, followed by materials 1 to 2 meters in length, and finally materials 0.5 to 1.5 meters in length. Arrangement is arbitrary according to the principle of long before short. Materials of the same length should be evenly distributed and not stacked.

[0043] After the material is ready for discharge, the electrical control system starts processing. During the processing of angle steel material, the electromagnetic clutch 10 in the automatic discharge channel 1 will disengage and the material will not be conveyed. After the material is cut off, the entire feeding system starts, the electromagnetic clutch 10 is energized, the discharge motor 12 drives the first roller group 6 to rotate, the roller motor drives the second roller group 5 and the third roller group 25 to rotate, the first roller group 6, the second roller group 5 and the third roller group 25 drive the angle steel material to move forward, the inductive switch senses the angle steel material and memorizes the material length and position, the V-port receiving seat with the V-port facing upward is lower than the material channel position and is pending, and the parameter signal at this time is fed back, the flipping electromagnet in the electromagnet flipping mechanism 8 picks up the angle steel material and flips the material, flips it 180° and places it on the positioning part 19 of the lifting device, before the next material is conveyed, the flipping electromagnet flips back to its original position and is pending.

[0044] After the second angle steel material is processed, it is fed into the automatic discharge channel 1 according to the previously memorized length position. The material is stopped at the previous switch position. The material length position is memorized according to the status of the induction switch, and a feedback signal is sent. Then the electromagnet flipping mechanism 8 starts flipping the material and stacks the angle steel on the positioning part 19 of the stacking device 2. This process is repeated to complete the feeding of the entire material.

[0045] The palletizing device 2 sets different lifting distances according to the material specifications and thickness, referring to the internal parameter table library, for different specifications of angle steel. The flipping and unloading position of the electromagnet flipping mechanism 8 is fixed. The palletizing device 2, according to the material specifications, thickness, and number of stacked materials, automatically raises the lifting frame 20 and the positioning part 19 to the correct position to receive the material through internal calculation and control of the electrical control system. After receiving a full layer of material, it automatically lowers by the height of one material. The palletizing device 2 can carry up to 10 layers of palletized material.

[0046] After 10 layers of material are stacked, the lifting frame 20 of the stacking device 2 rises to the designated position, the receiving frame 24 extends out, the lifting frame 20 descends to the lowest point, the receiving frame 24 receives the 10 layers of stacked material and moves out, the conveying motor 21 starts, driving the cam transmission frame 23 to work, and through the cam progression structure, the angle steel material is moved a certain distance. The receiving conveying buffer device 3 is equipped with a first diffuse reflection induction switch for angle steel material near the stacking device and a second diffuse reflection induction switch for angle steel material far away from the stacking device. When the material is detected by the first diffuse reflection induction switch, the conveying stops to ensure that it is removed from the receiving frame 24.

[0047] Repeat the above operation. When the material receiving and conveying buffer device 3 is full of angle steel material, the second diffuse reflection sensor switch will trigger a full alarm, and the material will be removed manually. Then repeat the above operation.

[0048] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
