[0052] During operation, the first servo motor 33 drives the turning frame 32 to rotate, so that the electromagnet 31 attracts the angle steel 10 and turns the angle steel 10 .

[0053] The present invention arranges the position and quantity of the automatic flipping mechanism 3 according to the length of each material specification, so that a set of automatic flipping mechanisms 3 can take into account the flipping of angle steels 10 of various lengths, and each set of electromagnets 31 is provided with a floating structure for effectively adsorbing angle steels 10 of different models and thicknesses. The floating structure floats up and down through the compression of a low-hardness silicone block or through the compression of a spring with a guide column, a linear bearing, a copper sleeve and other structures.

[0054] As a further explanation of this embodiment, refer to Fig. 9 and Fig.11 The automatic detection mechanism 4 includes a main frame 41, a camera 42, a light source 43, a mounting seat 44, a second servo motor 45 and a gear rack transmission component. The mounting seat 44 is fixed on the main frame 41, and the camera 42 and the light source 43 are symmetrically arranged on the mounting seat 44. The camera 42 and the light source 43 are installed with a gear rack transmission component, and the gear rack transmission component is driven by the second servo motor 45.

[0055] The main frame 41 of the present invention is made of aluminum, which can reduce the weight of its own frame, which is conducive to the high-speed stable operation and fast response of the detection device. In order to meet the high-precision function of the detection device, the camera 42 and the light source 43 are arranged on the same mounting seat 44.

The aluminum profile has a small mass, reduced power, small inertia and fast response speed. The M-type electromagnet can absorb positive and negative V-mouth angle steels, and the floating structure is a guide column. The shaft sleeve combination relies on its own gravity to achieve up and down floating, and can also be set to a floating structure such as a spring or a guide column to achieve the function. The truss manipulator 7 can be used for two production lines.

[0060] As a further explanation of this embodiment, refer to Figure 1 The angle steel automated production line also includes a conveying channel, which includes a feed channel 20, a moving channel 14 and a discharge channel 15.

[0061] The feed channel 20 of the present invention is composed of a feed frame, a roller group, a chain drive, a guide rail slider, a flip support frame, etc., and is used for conveying the angle steel 10 to the cutting angle. The feed channel rollers can convey minimum angle steels of different lengths according to the layout of different spacings. The front end part of the feed channel 20 is provided with a guide rail, which is connected to the movable material channel 14 to realize the material channel movement function. The feed channel 20 is provided with a flip support frame to facilitate the installation of the automatic flipping mechanism 3 and to ensure the consistency of the installation accuracy of each automatic flipping mechanism 3. The inner side of the feed channel 20 is connected to the guide rail mounting frame of the automatic detection mechanism 4. This mounting frame and the feed channel frame are an integral structure, which mainly ensures the installation position accuracy between detection, flipping, and conveying of the angle steel 10 through processing accuracy, thereby realizing the functions of angle steel 10 transmission, flipping, detection, etc.

[0062] The mobile material channel 14 is composed of a cantilever frame, a guide rail slider, a gear rack, a chain drive, a roller and other parts. The movement of the material channel is mainly achieved by the fourth servo motor controlling the gear drive. The transportation of the angle steel 10 is achieved by the fourth servo motor controlling the chain drive to drive the roller. The mobile material channel 14 is precisely controlled by the fourth servo motor to move in and out of the angle steel line position, which facilitates the normal transportation of the angle steel 10 and leaves space for waste disposal.

[0063] The discharge channel 15 is composed of a discharge frame, a roller group, a chain drive, a flip support frame, etc., and is used to transport the angle steel 10 to the automatic angle cutting machine 6. The material channel rollers can transport minimum material angle steels of different lengths according to the layout of different spacings. The discharge channel 15 is provided with a flip support frame to facilitate the installation of the automatic flipping mechanism 3 and to ensure the consistency of the installation accuracy of each flipping device. The conveying channel frame and the flip support frame are an integral structure. The installation position accuracy of the automatic flipping mechanism 3 and the angle steel 10 conveying is guaranteed through processing accuracy, thereby realizing the functions of angle steel 10 transmission and flipping.

[0064] Among them, refer to Figure 1 and Fig. 9 A buffer platform 19 is provided on one side of the inlet and outlet channels. The buffer platform 19 is welded with profiles, has a simple and stable structure, and when the transfer system is in motion, the stacking robot 51 or the truss manipulator 7 performs buffering in the material placement area to save time.

[0065] As a further explanation of this embodiment, refer to Figure 1 The angle steel automated production line also includes a transfer system, which includes a logistics trolley 17 and a reversing platform 18.

[0066] The automatic material transfer mechanism 2 of the present invention can be included in the transfer system. The automatic material transfer mechanism 2 is composed of a material pallet, a conveying roller, a chain drive, an induction switch, a lifting mechanism, etc. The lifting mechanism is driven by a screw lift to drive a scissor-fork type connecting rod, and the lifting function is realized by moving the guide roller. The automatic material transfer mechanism 2 drives the roller through the chain drive to convey the material on the pallet, and realizes the conveying of full pallets and the receiving of empty pallets through the scissor-fork lifting mechanism.

[0067] The logistics trolley 17 can use AGV or RGV or when manually operated, the material pallet is transported to the plate chain mechanism through the automatic material transfer mechanism 2 for manual assisted unloading, and then transported out of the production line. The logistics trolley 17 has a double-layer material roller conveyor, the bottom layer conveys empty pallets, and the top layer conveys full pallets.

[0068] The reversing platform 18 adopts a hollow rotating platform, which is used for RGV trolley track conversion. When the logistics trolley 17 is on the reversing platform 18, the reversing platform 18 automatically rotates and docks with the vertical track, so that the logistics trolley 17 runs along the vertical track. This mechanism has high load-bearing and high-precision repeated positioning performance.

[0069] Working principle:

[0070] The angle steel host is marked, punched, and the waste beans after shearing slide through the waste hopper 13 into the waste mobile recycling box 12. When the angle steel 10 is a certain length of material, the trolley clamp on the host line transports the angle steel tailings to the shearing opening, and the cylinder 101 drives the mechanical hook 102 to move. After hooking the angle steel 10, the cylinder 101 retracts, and the mobile material channel 14 moves out of the center position of the angle steel line to make room for the angle steel 10 tailings to fall into the waste mobile recycling box 12. When the detection switch detects that the waste mobile recycling box 12 is full, the full waste mobile recycling box 12 moves to one end, and the other empty waste mobile recycling box 12 moves to the center line position of the angle steel line and waits for work;

[0071] When the angle steel 10 is normally conveyed after the main process of the angle steel, the movable material channel 14 needs to be moved to the center position of the angle steel line, and the movable material channel 14 and the feed channel 20 are kept in the same position to convey the angle steel 10; for the angle steel without the post-angle cutting process, the electrical control positioning device is actuated according to the PLC control program and the detection of the shooting switch, etc., as the 0 position of the material block, the angle steel material is blocked, and the automatic turning mechanism 3 turns the positive V-mouth of the feed channel 20 into an inverted V-mouth, and the automatic detection mechanism 4 moves to detect the length, end distance, hole distance, hole position and other parameters of the angle steel 10 on the automatic turning mechanism 3, and the stacking robot 51 grabs the materials on the automatic turning mechanism 3 and controls the classification according to the internal program, and then stacks them on different pallets;

[0072] When the angle steel 10 has a cutting process, the angle steel 10 is transmitted to the automatic cutting machine 6, and the clamp moving device 68 clamps the angle steel 10 and continues to convey it to the position. The angle steel 10 at this position is used as the 0 position of the cutting position. According to the program control, the first group of cutting mechanisms 60 automatically controls the cutting operation, and the second group of cutting mechanisms 60 automatically controls the cutting operation to complete the cutting of the A and B sides of the angle steel, cutting of limbs and back cutting. The knife die 63 is a right-angle double-edged, rotary multi-directional cutting die. The change of the required cutting angle of the angle steel 10 only requires automatic adjustment of the knife disc 62, and the angle steel 10 does not need to rotate. Therefore, its cutting operation occupies a small area and has a small cutting error. The knife disc 62 can be moved to process different types of angle steels. The combined cutting of the two groups of knife discs 62 can meet the needs of the A and B sides of the angle steel 10, cutting of limbs and back cutting. After the cutting is completed, the angle steel 10 is conveyed through the discharge channel 15.

[0073] The angle steel 10 without post-processing after cutting continues to be transported on the discharge channel 15. When the length of the angle steel 10 is small, the material blocking and positioning device on the discharge channel 15 is activated, and the automatic flipping mechanism 3 flips the angle steel 10 after cutting, and flips the positive V-mouth of the angle steel 10 on the discharge channel 15 into an inverted V-mouth. The stacking robot 51 grabs the materials on the automatic flipping mechanism 3, controls the classification according to the internal program, and then stacks and places them on the pallet;

[0074] When the angle steel 10 is long, the material stopper and positioning device at the end of the discharge channel 15 is activated, and the automatic flipping mechanism 3 flips the positive V-mouth of the angle steel 10 of the discharge channel 15 into an inverted V-mouth. The truss manipulator 7 grabs the angle steel 10 on the automatic flipping mechanism 3 and stacks it on the pallet according to the internal program control;

[0075] When the stacking pallet is full, the automatic material transfer mechanism 2 is activated, and at the same time, the top roller of the logistics trolley 17 is activated, and the pallet is transported to the logistics trolley 17 through the automatic material transfer mechanism 2. After receiving the full pallet, the automatic material transfer mechanism 2 descends to the bottom height of the logistics trolley 17, and the conveying roller of the automatic material transfer mechanism 2 is activated, and at the same time, the conveying roller of the bottom layer of the logistics trolley 17 is activated to transfer the empty pallet on the bottom layer of the trolley to the automatic material transfer mechanism 2. Then the automatic material transfer mechanism 2 rises to the stacking height of the angle steel 10, waiting for the angle steel to be unloaded for stacking. The logistics trolley 17 is transported along the planned route, and when it is delivered to the vertical track, the trolley is turned by the reversing platform 18, perpendicular to the horizontal guide rail, to transport the material out of the production line.
