Description

Technical Field

[0001] The present application relates to the field of angle steel processing, and in particular to an automatic feeding device for a steel structure angle steel production line. Background Art

[0002] Angle steel is one of the materials widely used in the construction and manufacturing industries. Its production and processing technology has been continuously improved, which has improved production efficiency and product quality. In the steel structure manufacturing industry, the application of automated production lines has significantly improved the continuity and stability of production, and reduced labor costs and labor intensity. However, during the transportation of angle steel, in order to make the placement of the angle steel more stable, the two angle steel openings are generally placed opposite to each other, so that the two angle steels form a rectangular structure. However, the relative placement of the two angle steel openings also brings inconvenience to the subsequent processing, because in the subsequent processing of the angle steel, it is necessary to keep each angle steel at the set placement angle and transport it to the production line. Therefore, in the subsequent processing process, the angle steel needs to be adjusted in a unified direction to smoothly enter the production line.

[0003] At present, when adjusting the direction of angle steel, workers are required to do manual operation, which is flexible but inefficient, easily leads to worker fatigue and has high labor intensity. Summary of the invention

[0004] In order to reduce the labor intensity of the staff and improve the operating efficiency, the present application provides an automatic feeding device for a steel structure angle steel production line.

[0005] The automatic feeding device for a steel structure angle steel production line provided in this application adopts the following technical solution: An automatic feeding device for a steel structure angle steel production line, wherein the angle steel is placed on a mounting frame, the mounting frame comprises a bottom frame and a frame vertically fixed to one side of the bottom frame, a placement space for placing the angle steel is formed between the bottom frame and the two frames, the device comprises a placement platform for placing the mounting frame, a feeding platform arranged at the feeding end of the production line, a manipulator arranged between the placement platform and the feeding platform for automatically adjusting the direction of the angle steel on the placement platform and placing it on the feeding platform, and a pushing component installed on the feeding platform for pushing the angle steel on the feeding platform to the production line in sequence.

[0006] By adopting the above technical solution, the design of the installation frame allows the angle steel to be firmly placed in the placement space formed by it, which is convenient for subsequent automated processing. The placement platform is used to carry the installation frame to ensure that the angle steel is in a stable state before being grabbed by the manipulator. The manipulator can accurately grab the angle steel from the placement platform and rotate it to the set angle to complete the direction adjustment. The feeding platform is provided with a pushing component, which can push the angle steel to the production line in turn after the manipulator places the angle steel on the feeding platform, ensuring the continuity of the production process. This automatic feeding device not only improves work efficiency and reduces the labor intensity of workers, but also enhances the stability and reliability of production.

[0007] Optionally, the manipulator includes a mounting frame whose length direction is consistent with the direction of the line connecting the placement platform and the feeding platform, a linear drive component installed on the mounting frame, a driving cylinder fixedly connected to the movable part of the linear drive component, a rotating motor fixedly connected to the piston rod of the driving cylinder, a telescopic cylinder fixedly connected to the output shaft of the rotating motor, and an adsorption plate fixedly connected to the piston rod of the telescopic cylinder, wherein suction cups for adsorbing and fixing the angle steel are arranged at intervals on the adsorption plate along the axial direction of the output shaft of the rotating motor, and when the output shaft of the rotating motor rotates, the adsorption plate can drive the angle steel to rotate at a set angle to adjust the direction of the angle steel.

[0008] By adopting the above technical solution, the manipulator can automatically adjust the direction of the angle steel. Specifically, the linear drive can accurately control the horizontal movement position of the adsorption plate to ensure that the suction cup is accurately adsorbed on the angle steel; the rotary motor cooperates with the telescopic cylinder to enable the adsorption plate to move in multiple degrees of freedom, thereby adjusting the angle steel from any angle to the set direction. This not only greatly improves production efficiency and reduces the need for manual intervention, but also reduces the labor intensity of workers and improves the automation and stability of the entire production line.

[0009] Optionally, the interior of the adsorption plate is a hollow structure, and each of the suction cups is connected to the inner cavity of the adsorption plate. An air pump for discharging the gas in the adsorption plate so that the suction cup is adsorbed on the angle steel and a ventilation pipe connected to one side of the adsorption plate are also provided. The air pump is connected to the adsorption plate through the air pipe, and a control valve is installed on the ventilation pipe.

[0010] By adopting the above technical solution, the vacuum pump can discharge the gas in the adsorption plate, so that the suction cup can be firmly adsorbed on the angle steel, ensuring the stability of the angle steel during the grasping process. At the same time, the design of the vent pipe and control valve facilitates rapid inflation when the angle steel needs to be released, thereby quickly releasing the adsorption state and improving the operational flexibility and work efficiency of the manipulator.

[0011] Optionally, the placement platform includes a placement frame, support legs fixed to the lower side of the placement frame for supporting the placement frame, a lifting plate slidably connected to the placement frame, and a lifting member for driving the lifting plate to slide vertically.

[0012] By adopting the above technical solution, the placement frame can not only accommodate multiple angle steels, but also stand firmly on the ground through the support legs, ensuring the stability and safety of the entire device. The lifting plate slidably connected to the placement frame cooperates with the lifting parts to smoothly lift the angle steel when needed, making it easier for the robot to grab and adjust the direction. This design not only improves the degree of automation of the loading process, but also reduces the need for manual intervention, thereby improving production efficiency and reducing labor intensity.

[0013] Optionally, the feeding platform includes a first table top that abuts the angle steel production line, a second table top located on the side of the first table top away from the angle steel production line, and a limiting member installed on the first table top for fixing the position of the angle steel on the first table top, and the pushing assembly is installed on the second table top.

[0014] By adopting the above technical solution, the angle steel can be placed on the first table top and the second table top, and when the manipulator has placed the angle steel, the manipulator can slide out from between the first table top and the second table top, and the limiter can fix the position of the angle steel on the first table top and the second table top, so that the pushing component can smoothly push the angle steel to the angle steel production line.

[0015] Optionally, the limiting member includes two mutually parallel limiting plates slidably connected to the first table top and two limiting cylinders that respectively drive the two limiting plates to slide. The two limiting cylinders are respectively fixed to the first table top, and the piston rods of the two limiting cylinders are respectively connected to the two limiting plates.

[0016] By adopting the above technical solution, the limiter can effectively fix the position of the angle steel on the first table and the second table, ensuring the stability and accuracy of the angle steel during the conveying process. After an angle steel is pushed onto the angle steel conveying line, the piston rod of the limiter cylinder can push the two limiter plates relatively close to each other, so that the two limiter plates clamp the remaining angle steel.

[0017] Optionally, the end of the limit cylinder piston rod is slidably connected to a connecting rod, and a limit spring is sleeved on the limit cylinder piston rod and the connecting rod. The two ends of the limit spring are respectively fixed to the first table top and the limit plate, and one end of the connecting rod away from the limit cylinder is fixed to the limit plate.

[0018] Optionally, the pushing assembly includes a pushing cylinder fixedly connected to the second table surface, a driving rod rotatably connected to the piston rod of the pushing cylinder, a push plate fixedly connected to one end of the driving rod away from the pushing cylinder, and two push rods slidably connected to the second table surface. A follower is arranged between the driving rod and the second table surface. When the piston rod of the pushing cylinder is extended or retracted, the follower drives the driving rod to rotate so that the push plate alternately pushes the push rod to move.

[0019] By adopting the above technical solution, the piston rod of the pushing cylinder is extended and retracted through the design of the driving rod and the follower, so that the push plate can alternately push the two push rods to move in the horizontal direction, thereby ensuring that one angle steel can be pushed onto the angle steel production line each time, and there will be no situation in which the push rod is pushed between two adjacent angle steels due to the even number of angle steels on the first table.

[0020] Optionally, the follower includes a follower cylinder fixedly connected to the second table surface and a follower block fixedly connected to the side wall of the driving rod, the follower cylinder being provided with a follower groove for the follower block to be embedded and slide, the follower groove including a first groove provided on the inner wall of the follower cylinder and a second groove provided on the inner wall of the follower cylinder, two first grooves are provided, two second grooves are provided, the two first grooves and the two second grooves are staggered, two ends of the first groove are connected with the two second grooves, and two ends of the second groove are connected with the two first grooves, when the pushing cylinder extends and drives the driving rod to move, the follower block slides in the first groove, when the pushing cylinder contracts and drives the driving rod to move, the follower block slides in the second groove, and when the follower block slides from the first groove to the second groove, the follower block drives the driving rod to rotate a set angle.

[0021] By adopting the above technical solution, when the follower block slides in the follower groove, when it slides from the first groove to the second groove or vice versa, the rotation angle of the driving rod can be accurately controlled, thereby ensuring that the push plate alternately pushes the push rod to move, and the angle steel is pushed in an orderly manner. This design not only improves the automation and reliability of the angle steel feeding process, but also significantly reduces the need for manual intervention, reduces labor costs, and improves production efficiency.

[0022] Optionally, a fixed cylinder with a U-shaped cross-section is fixedly connected to the second table top, an embedding space for the push rod to be embedded is formed between the fixed cylinder and the second table top, a baffle is fixedly connected to the second table top, and a return spring is fixedly connected between the baffle and each of the push rods.

[0023] By adopting the above technical solution, the embedded space between the fixed cylinder and the second table can effectively limit the position of the push rod, preventing it from deviating or leaving the track during movement, thereby ensuring that the push rod can accurately cooperate with the push plate to complete the pushing action of the angle steel. At the same time, the design of the baffle and the reset spring can quickly reset the push rod after each push is completed, ensuring the normal operation of the next cycle and improving the working efficiency and reliability of the entire device.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the coordinated work of the manipulator and the pushing component, the angle steel is automatically adjusted and transported from the placement platform to the feeding platform, which greatly improves production efficiency and reduces manual dependence; 2. No need to manually adjust the direction of the angle steel, which avoids the fatigue caused by frequent repetitive labor of workers and significantly reduces the labor intensity of workers; 3. The robot can accurately rotate the angle steel to a set angle, ensuring that each angle steel can be accurately adjusted to the required direction, ensuring the stability of the production line and the quality of the product.

[0034] Reference Figure 1 At present, when the angle steel is transported, the angle steel needs to be placed in the installation frame 1. After being transported to the destination, the installation frame 1 is directly lifted from the transport vehicle by a crane and moved to a suitable position. The installation frame 1 includes a rectangular bottom frame 11 and a frame 12 vertically fixed to one side of the bottom frame 11. The frame 12 can block the angle steel to prevent the angle steel from falling from the installation frame 1.

[0035] The present application embodiment discloses an automatic feeding device for a steel structure angle steel production line. Figure 2 The automatic feeding device for the steel structure angle steel production line includes a placement platform 2 for placing an installation frame 1, a feeding platform 3 arranged at the feeding end of the angle steel production line, a manipulator 4 arranged between the placement platform 2 and the feeding platform 3 for automatically adjusting the direction of the angle steel on the placement platform 2 and placing it on the feeding platform 3, and a pushing component 5 installed on the feeding platform 3 for pushing the angle steel on the feeding platform 3 to the production line in sequence.

[0036] Reference Figure 2 and Figure 3The manipulator 4 includes a mounting frame 41 located on one side of the feeding platform 3 and the placing platform 2, a linear driving member 42 mounted on the mounting frame 41, a driving cylinder 43 fixedly connected to the movable part of the linear driving member 42, a rotating motor 44 fixedly connected to the piston rod of the driving cylinder 43, a telescopic cylinder 45 fixedly connected to the output shaft of the rotating motor 44, and an adsorption plate 46 fixedly connected to the piston rod of the telescopic cylinder 45. Among them, the linear driving member 42 can use a motor screw or a linear motor, as long as it can drive the driving cylinder 43 to move along the length direction of the linear driving member 42. The length direction of the linear driving member 42 is the same as the direction of the connection between the placing platform 2 and the feeding platform 3, so that the linear driving member 42 can drive the adsorption plate 46 to move from the placing platform 2 to the feeding platform 3, so as to transport the angle steel on the placing platform 2 to the feeding platform 3. The output shaft of the rotating motor 44 is arranged toward the feeding platform 3, and a plurality of suction cups 47 are arranged at intervals along the axial direction of the output shaft of the rotating motor 44 on the suction plate 46, and a plurality of angle steels can be sucked to the feeding platform 3 through the suction cups 47. If the direction of the angle steel sucked to the feeding platform 3 is consistent with the set direction, the angle steel can be directly placed on the feeding platform 3; if the angle steel sucked to the feeding platform 3 is opposite to the set direction and the direction of the angle steel needs to be adjusted, the suction cup can be driven by the rotating motor 44 to rotate 180 degrees, and the up and down direction of the angle steel can be flipped 180 degrees to adjust the placement direction of the angle steel.

[0037] Reference Figure 3 and Figure 4 The adsorption plate 46 is a hollow cavity structure, and each suction cup 47 is connected to the inner cavity of the adsorption plate 46. Therefore, an air pump for discharging the gas in the suction cup 47 so that the suction cup 47 can be smoothly adsorbed on the angle steel is also provided on one side of the adsorption plate 46, and a vent pipe 49 fixed to the side wall of the adsorption plate 46 and connected to the inner cavity of the adsorption plate 46 is provided. A control valve for controlling the opening and closing of the vent pipe 49 is installed on the vent pipe 49. When in use, after the suction cup 47 abuts against the angle steel, the gas in the suction cup 47 can be extracted through the air extraction pipe 48, so that the suction cup 47 can be firmly adsorbed on the angle steel; and when the angle steel is moved to the feeding platform 3, when it is necessary to release the fixed relationship between the suction cup 47 and the angle steel, the control valve can be directly operated to open, so that the external gas can pass through the inner hole of the adsorption plate 46 to reach between the suction cup 47 and the angle steel, and release the fixed relationship between the suction cup 47 and the angle steel.

[0038] Reference Figure 5The placement platform 2 includes a placement frame 21, a support leg 22 fixed to the lower side of the placement frame 21, a lifting plate 23 slidably connected to the placement frame 21, and a lifting member 24 for driving the lifting plate 23 to slide vertically. The width of the lifting plate 23 is consistent with the width of the inner hole of the bottom frame 11. The lifting member 24 can be a cylinder or a scissor lift, so that when the installation frame 1 is placed on the placement frame 21, the suction plate can drive the suction cup 47 to absorb the top layer of angle steel in the installation frame 1. At this time, the lifting member 24 drives the lifting plate 23 to rise to a set height, and the lifting plate 23 slides in the installation frame 1 to lift the angle steel, so that the suction plate can absorb the angle steel again.

[0039] Reference Figure 6 The feeding platform 3 includes a first table 31 that abuts against the angle steel production line, a second table 32 located on the side of the first table 31 away from the angle steel production line, and a limiter 33 connected between the first table 31 and the second table 32 for fixing the position of the angle steel on the first table 31 and the second table 32. The pushing assembly 5 is installed on the second table 32. An escape space 34 is formed between the first table 31 and the second table 32 for the manipulator 4 to slide. When the manipulator 4 drives the angle steel to the first table 31 and the second table 32, or drives the angle steel to flip and place it on the first table 31 and the second table 32, the manipulator 4 will be located in the escape space 34 and slide in the escape space 34, and the manipulator 4 will not interfere with the feeding platform 3.

[0040] The limiting member 33 may be installed on the first table top 31 or on the second table top 32 . The present application takes the example of the limiting member 33 being installed on the first table top 31 for explanation.

[0041] Reference Figure 6 The limiting member 33 includes two limiting plates 331 parallel to each other and slidably connected to the first table 31, and two limiting cylinders 332 that respectively drive the two limiting plates 331 to slide. The two limiting cylinders 332 are respectively fixed to the opposite sides of the first table 31. The two limiting cylinders 332 can drive the two limiting plates 331 to move relatively close to each other or away from each other, so as to clamp and fix the angle steel placed on the first table 31 or open the space between the two limiting plates 331, so as to place the angle steel between the two limiting plates 331. When the angle steel is placed on the first table 31 by the manipulator 4 and the angle steel is located between the two limiting plates 331, the two limiting cylinders 332 can drive the two limiting plates 331 to move relatively close to each other, so as to clamp the angle steel and fix the position of the angle steel on the first table 31.

[0042] Among them, a connecting rod 333 is slidably connected to the piston rod of each limiting cylinder 332, and a limiting spring 334 is sleeved on the piston rod of the limiting cylinder 332 and the connecting rod 333, and the two ends of the limiting spring 334 are respectively in contact with the first table 31 and the limiting plate 331. When the limiting cylinder 332 drives the limiting plate 331 to contact the angle steel to fix the position of the angle steel on the first table 31, the limiting plate 331 will be firmly in contact with the angle steel under the contact of the limiting spring 334, so that the fixing of the angle steel is more secure. At the same time, the precision requirement for the telescopic length of the piston rod of the limiting cylinder 332 is avoided, and the operation is more convenient; at the same time, the setting of the limiting spring 334 also makes it easy to push the angle steel located between the two limiting plates 331 to the angle steel production line through the pushing component 5.

[0043] When the angle steel is placed on the first table 31 and fixed in the middle position of the first table 31 by two limit plates 331, the middle angle steel can be pushed from the first table 31 to the angle steel production line through the pushing component 5. When the middle angle steel is pushed to the angle steel production line, the two limit plates 331 are relatively close to each other under the elastic force of the limit spring 334, so as to re-clamp the angle steel. Then, the piston rods of the two limit cylinders 332 are extended to a set length, so that the limit spring 334 is in a compressed state again.

[0044] Reference Figure 6 and Figure 7 It can be understood that when the angle steels on the first table 31 are a cardinal number, the pushing assembly 5 can directly push an angle steel located in the middle to the angle steel production line; when the angle steels on the first table 31 are an even number, the connection between the two angle steels located in the middle will be located in the middle of the first table 31. In order to enable the pushing assembly 5 to smoothly push an angle steel to the angle steel production line every time, the pushing assembly 5 includes two mutually parallel push rods 51 slidably connected to the second table 32, a pushing cylinder 52 fixedly connected to the second table 32, a driving rod 53 rotatably connected to the piston rod of the pushing cylinder 52, and a pushing plate 54 fixedly connected to the end of the driving rod 53 away from the pushing cylinder 52, and the pushing plate 54 is located on the side wall of the driving rod 53. The two push rods 51 are provided with a follower 55 between the second table 32 and the driving rod 53, and when the piston rod of the pushing cylinder 52 is extended and retracted once, the driving rod 53 rotates 180 degrees. Under normal conditions, the push plate 54 is located at the end of one push rod 51. When the piston rod of the push cylinder 52 drives the push plate 54 to extend, the push plate 54 will push the push rod 51 to slide on the second table 32, so that the push rod 51 pushes the corresponding angle steel to move. When the piston rod of the push cylinder 52 retracts, the follower 55 drives the rod 53 to rotate 180 degrees. At this time, the push plate 54 will rotate from one end of the push rod 51 to the other end of the push rod 51. At this time, when the piston rod of the push cylinder 52 extends, the push plate 54 will push the other push rod 51 to move.

[0045] Specifically, of the two push rods 51, one push rod 51 is located in the middle of the width of the second table 32, and the other push rod 51 is located on one side of the push rod 51, and the distance between the two push rods 51 is half of the width of the angle steel, so that when the number of angle steels on the second table 32 is an odd number, the push rod 51 located in the middle of the width of the second table 32 will push the angle steel located in the middle to move; and when the angle steel located in the middle is moved to the angle steel production line, the number of angle steels located on the second table 32 is an even number, and the push rod 51 located in the middle is opposite to the intersection of the two angle steels. At this time, the angle steel opposite to it can be pushed to the angle steel production line by the other push rod 51, and the operation is more convenient and flexible.

[0046] Among them, in order to reduce the probability that when the push rod 51 pushes an angle steel, the angle steels on both sides of the angle steel move together, an anti-skid pad can be set on the first platform, or an anti-skid pattern can be processed on the first platform, so that the friction between the angle steel and the first table 31 is greater than the friction between two adjacent angle steels. When the push rod 51 pushes the angle steel, the corresponding angle steel can be smoothly pushed to the angle steel production line, while the angle steel in contact with the angle steel does not move with the angle steel under the action of the friction force of the first table 31. When an angle steel moves to the angle steel production line, the remaining angle steels can slide to the middle of the first platform under the action of the limit cylinder 332 and the limit spring 334.

[0047] Reference Figure 7 A fixed cylinder 321 for guiding the push rod 51 is also fixedly connected to the second table surface 32. The cross-section of the fixed cylinder 321 is U-shaped. The opening of the fixed cylinder 321 faces the second table surface 32, and an embedding space for the driving rod 53 to be embedded is formed between the fixed cylinder 321 and the second table surface 32, so that the push rod 51 can slide smoothly in the embedding space.

[0048] A baffle plate 322 is fixedly connected to each push rod 51 on the second table surface 32, and a return spring 323 is fixedly connected between the baffle plate 322 and the corresponding push rod 51, so that when the push cylinder 52 pushes the push rod 51 to move through the push plate 54, when the piston rod of the push cylinder 52 retracts, the push rod 51 will be reset under the elastic force of the return spring 323.

[0049] Reference Figure 7 and Figure 8The follower 55 includes a follower cylinder 551 fixedly connected to the second table 32 and a follower block 552 fixedly connected to the side wall of the driving rod 53. At the same time, a follower groove 553 is provided in the follower cylinder 551 for the follower block 552 to be embedded and slide. The follower groove 553 includes a first groove 5531 provided on the inner wall of the follower cylinder 551 and a second groove 5532 provided on the inner wall of the follower cylinder 551. The second groove 5532 is connected to the first groove 5531 at one end away from the piston rod of the pushing cylinder 52. When the piston rod of the push cylinder 52 is extended, the follower block 552 will slide along the first groove 5531 to the connecting point between the first groove 5531 and the second groove 5532. When the piston rod of the push cylinder 52 is retracted, the follower block 552 will slide along the second groove 5532 to the end of the second groove 5532 away from the first groove 5531. When the follower block 552 slides from the end of the first groove 5531 away from the second groove 5532 to the end of the second groove 5532 away from the first groove 5531, the follower block 552 will also drive the driving rod 53 to rotate 180 degrees, so that the push plate 54 can rotate from being able to push one push rod 51 to the end of the other push rod 51, so that the push plate 54 can alternately push the two push rods 51 to slide.

[0050] Among them, there are two follower grooves 553 on the inner wall of the follower cylinder 551, and the two follower grooves 553 are connected to each other end to end, so that when the piston rod of the pushing cylinder 52 is extended and retracted, the follower block 552 can slide smoothly between the two follower grooves 553, so that the push plate 54 can smoothly push the two push rods 51 to slide alternately.

[0051] At the same time, an avoidance hole 324 for the push plate 54 to rotatably embed is opened on the second table 32 , so as to ensure that the push plate 54 can rotate smoothly without interfering with the second table 32 .

[0052] The implementation principle of the automatic feeding device for the steel structure angle steel production line of the embodiment of the present application is as follows: when in use, the installation frame 1 containing the angle steel is first placed on the set position of the placement platform 2 by a crane, etc., and then the top row of angle steels of the installation frame 1 is driven by the manipulator 4 to move to the feeding platform 3, and the position of the angle steels on the feeding platform 3 is fixed by the limit plate 331. Then, by starting the push cylinder 52, the piston rod of the cylinder 52 is pushed to reciprocate and retract, which can drive the driving rod 53 to rotate while retracting, and drive the push plate 54 to push the two push rods 51 to slide in turn, so as to realize the feeding of the angle steels in turn. Among them, when the angle steel is driven by the manipulator 4 to move from the installation frame 1 to the feeding platform 3, when the opening of the angle steel is facing upward, the manipulator 4 can directly translate the angle steel to the feeding platform 3; when the opening of the angle steel is facing downward, the driving cylinder 43 will drive the adsorption plate 46 to rotate 180 degrees, so as to adjust the direction of the angle steel and then place the angle steel on the feeding platform 3. And when the adsorption plate 46 rotates 180 degrees, the angle steel will rotate to the upper side of the rotating motor 44. At this time, after the angle steel is placed on the feeding platform 3, the rotating motor 44 can be driven by the telescopic cylinder 45 to move horizontally from the lower side of the angle steel to one side of the feeding platform 3, and then the adsorption plate 46 can be driven to rise by the driving cylinder 43.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
