Description

Technical Field

[0001] This invention belongs to the field of steel bar production and processing technology, and particularly relates to a steel bar conveying device. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, and sometimes square with rounded corners. In the processing of reinforcing bars, such as bending, tying, and welding, the reinforcing bars must first be conveyed to the corresponding equipment. The traditional method of conveying is manual. Because the reinforcing bars are long and heavy, manual conveying is not only time-consuming and labor-intensive, but also has high labor costs, low work efficiency, and certain safety hazards.

[0003] Chinese invention patent application (publication number: CN115178915A) discloses a bar steel conveying device for a rebar cage welding machine, belonging to the category of rebar feeding mechanisms for rebar cage welding machines. Its structure mainly consists of a material support bracket, connecting rods, hydraulic cylinders, a motor and reducer assembly, a chain, a moving frame, a roller assembly, a foot platform, a foot switch, and electrical components. The roller assembly is mounted on the upper part of the moving frame, and the motor and reducer assembly is mounted on the lower part of the moving frame. The moving frame is installed in a groove within the material support bracket. The hydraulic cylinder can drive the roller assembly to extend and retract. The motor and reducer assembly drives the rollers to rotate via the chain, and the rotation of the rollers drives the rebar conveying. Compared with existing technologies, this rebar conveying device can reduce manual labor intensity, improve work efficiency, and has good application value.

[0004] Chinese invention patent application (publication number: CN116275717A) discloses an automatic plate chain conveyor for rebar welding, comprising: a conveyor chain, a conveyor body, a heat insulation mechanism, a heat dissipation mechanism, a paving mechanism, and a drive mechanism. The conveyor body has supporting feet at its bottom and multiple conveyor chain plates. A drive mechanism is located between the conveyor chain plates, and the heat dissipation mechanism is covered by one set of conveyor chain plates. The beneficial effects of this invention are: during rebar welding, an electric push rod can be activated to cause the paving plate to rotate the rebar, facilitating welding at all angles; the positioning sleeve at the top of the heat insulation mechanism clamps the rebar at the welding point, thus connecting the heat insulation mechanism to the rebar. The heat insulation mechanism is transported along with the rebar on the conveyor chain, and the heat insulation plate at the bottom of the heat insulation mechanism prevents heat transfer to the conveyor chain; and the high-speed rotating fan blades inside the air duct transport cold air from the outside into the heat insulation enclosure, thereby rapidly reducing the temperature at the rebar welding point.

The longitudinal rebar conveying mechanism includes a first support, a movable frame, a fixed frame, and a first driving mechanism for driving the movable frame to move along the length direction of the first support. The longitudinal rebar feeding mechanism includes a second support, a longitudinal rebar storage rack, and a second driving mechanism for driving the longitudinal rebar storage rack to move to place the longitudinal rebar on the fixed frame via a guide groove of a conveying slide rail. The second driving mechanism includes a longitudinal driving mechanism for driving the longitudinal rebar storage rack to move perpendicular to the length direction of the first support and a vertical driving mechanism for driving the longitudinal rebar storage rack to move vertically.

[0048] like Figure 1-16As shown, a rebar conveying device includes a frame 1, a receiving mechanism 2, a tilting mechanism 3, and a conveying mechanism 4. The frame 1 is horizontally arranged. The receiving mechanism 2 includes support columns 21, connecting columns 22, receiving components 23, and guide plates 24. The support columns 21 are vertically arranged in pairs on the front and rear sides of the top of the frame 1, and multiple sets are spaced apart along the left and right horizontal direction. Two connecting columns 22 are arranged along the left and right horizontal direction, and the bottom surfaces of the two connecting columns 22 are fixedly connected to the top surfaces of the support columns 21 on the front and rear sides of the top of the frame 1, respectively. The receiving components 23 are respectively mounted on the connecting columns 22 through the tilting mechanism 3. The guide plates 24 are vertically arranged on opposite sides of each set of support columns 21, with the opposite sides of the two guide plates 24 tilted downwards and spaced apart to form a discharge channel 25. The conveying mechanism 4 is located in the middle of the top surface of the frame 1. After the steel bars enter the receiving assembly 23 of the receiving mechanism 2, the steel bars placed in the receiving assembly 23 are dropped into the guide plate 24 by the flipping mechanism 3, and then fall from the discharge channel 25 formed by the two guide plates 24 to the conveying mechanism 4. The conveying mechanism 4 transports the steel bars to the next process.

[0049] like Figure 7-8 As shown, the receiving assembly 23 includes a fixed plate 231 and a movable plate 232; the fixed plate 231 and the movable plate 232 have an L-shaped structure; two fixed plates 231 are provided along the left and right horizontal direction, and the bottom surfaces of the two fixed columns are respectively located above the two connecting columns 22 through a flipping mechanism 3, with the openings of the two fixed plates 231 facing each other; the movable plate 232 is provided along the left and right horizontal direction, and two movable plates 232 are provided, respectively connected to the two fixed plates 231 in a mirror-image manner through the flipping mechanism 3, forming a receiving groove in the middle of the movable plate 232 and the fixed plate 231, and the movable plate 232 can open or close the fixed plate 231 through the flipping mechanism 3. When the reinforcing bar is fed into the receiving groove formed by the movable plate 232 and the fixed plate 231, the flipping mechanism 3 opens the movable plate 232, thereby opening the fixed plate 231, allowing the reinforcing bar to fall out of the receiving assembly 23.

After the reinforcing bar is fed into the receiving groove formed by the movable plate 232 and the fixed plate 231, the tilting cylinder 312 is activated, causing the piston rod of the tilting cylinder 312 to retract. The first clamping piece 314 rotates upward based on the pin connection with the first clamping plate 313, thereby driving the movable plate 232 to rotate upward, so that the movable plate 232 opens the fixed plate 231, and the reinforcing bar can fall from the receiving assembly 23.

[0051] like Figure 11-12 As shown, the flipping mechanism 3 further includes a driven flipping component 32; multiple driven flipping components 32 are provided, respectively located on the left and right sides of the active flipping component 31, with intervals between the multiple driven flipping components 32. Each driven flipping component 32 includes a second mounting base 321, a second clamping plate 322, and a second clamping member 323; the second mounting base 321 is horizontally located on the top surface of the connecting column 22; the second clamping plate 322 is vertically fixed on the top surface of the second mounting base 321, and its left and right sides are provided with through-holes that are fixedly connected to the outer side and top surface of the fixed plate 231; the second clamping member 323 has a structure with a vertical lower part and an upper part that is inclined upwards away from the center of the frame 1, and its upper part is movably connected to the upper part of the second clamping plate 322 through a pin shaft, and the lower outer side of the second clamping member 323 is fixedly connected to the inner side of the movable plate 232. When the active flipping component 31 opens the movable plate 232, the second locking component 323 rotates upward based on the pin connection with the second locking plate 322, assisting the movable plate 232 in rotating, thereby ensuring flipping stability.

[0052] like Figure 13 As shown, it also includes a receiving guide trough 5; the receiving guide trough 5 is located in the middle of the top surface of the frame 1 along the left-right horizontal direction, below the discharge channel 25 formed by the guide plates 24, and its top surface is open; there are multiple receiving guide troughs 5, which are spaced apart along the left-right direction, and the conveying mechanism 4 is provided at the right end of each receiving guide trough 5. The steel bar falls from the receiving assembly 23, and then falls from the discharge channel 25 formed between the guide plates 24 onto the receiving guide trough 5 and the conveying mechanism 4.

[0053] like Figure 14-15 As shown, the conveying mechanism 4 includes a support assembly 41 and a conveying assembly 42. The support assembly 41 includes a mounting plate 411, a support plate 412, and a receiving seat 413. The mounting plate 411 is horizontally fixed to the center of the top surface of the frame 1, and has a through opening in the center of its top surface. The support plates 412 are vertically arranged and are arranged in pairs on the left and right sides of the mounting plate 411, with the two support plates 412 in each pair spaced apart. The receiving seats 413 are horizontally arranged front and back and fixed between the support plates 412, with the top surface of the receiving seat 413 flush with the bottom surface of the receiving guide 5. The conveying assembly 42 includes a motor 421, a fixed seat 422, a first rotating shaft 423, a fixed wheel 424, a movable seat 425, a second rotating shaft 426, and a movable wheel 427. The motor 421 is vertically arranged on the rear side of the top surface of the mounting plate 411, and its output shaft passes through the mounting plate 411. The bottom surface of the mounting plate 411 is rotatably connected to the mounting plate 411; the fixed seat 422 is horizontally positioned on the opening on the top surface of the mounting plate 411; the first rotating shaft 423 is vertically positioned in the middle of the top surface of the fixed seat 422, with its lower end passing through the fixed seat 422 and rotatably connected to it, and the lower end of the first rotating shaft 423 is connected to the output shaft of the motor 421 via a pulley; the fixed wheel 424 is fixedly sleeved on the upper part of the first rotating shaft 423; the movable seat 425 is horizontally positioned to the left and right and located in front of the fixed seat 422, with its bottom slidably connected to the mounting plate 411 via a movable component 43; the second rotating shaft 426 is vertically positioned, with its bottom end fixedly connected to the middle of the top surface of the movable seat 425; the movable wheel 427 is rotatably sleeved on the upper part of the second rotating shaft 426, and the movable wheel 427 is a horizontally positioned V-shaped roller, with a channel for the steel bar to travel between the V-shaped groove of the movable wheel 427 and the fixed wheel 424. After the reinforcing bars fall from the discharge channel 25 formed between the guide plates 24 onto the receiving guide 5 and the receiving seat 413 of the conveying component 42, the moving seat 425 is moved by the moving component 43, so that the moving seat 425 is close to the fixed seat 422, thereby making the moving wheel 427 close to the fixed wheel 424. The V-groove of the moving wheel 427 and the fixed wheel 424 clamp the reinforcing bars. Then the motor 421 is started, driving the fixed wheel 424 to rotate, driving the reinforcing bars to move between the fixed wheel 424 and the moving wheel 427, thereby conveying the reinforcing bars.

[0054] It also includes a moving component 43; the moving component 43 includes a slide rail 431, a slider 432, and a moving cylinder 433; two slide rails 431 are provided, respectively horizontally arranged on the left and right sides of the opening on the top surface of the mounting plate 411, and located in front of the fixed seat 422; the sliders 432 are slidably sleeved on the slide rails 431; the bottom surface of the moving seat 425 is fixedly mounted on the sliders 432; the moving cylinder 433 is horizontally arranged in front of the mounting plate 411, and its piston rod is fixedly connected to the moving seat 425. When the moving cylinder 433 is activated, the piston rod of the moving cylinder 433 extends, causing the fixed seat 422 to move on the slide rail 431 via the slider 432, thereby bringing the fixed seat 422 closer to the moving wheel 427.

When the motor 421 rotates, it drives the drive pulley 44 to rotate, which in turn drives the driven pulley 45 to rotate via the transmission belt, causing the first rotating shaft 423 to rotate, and the first rotating shaft 423 drives the fixed wheel 424 to rotate.

[0056] like Figure 1-2 As shown, it also includes a straightening machine 6, which is located at the left end of the frame 1, and its outlet is connected to the receiving assembly 23. The steel bar is first straightened in the straightening machine 6, and then enters the movable plate 232 and fixed seat 422 of the receiving assembly 23 from the outlet of the straightening machine 6. After entering a certain length, the straightening machine 6 cuts the steel bar.

[0057] The working principle of this invention is as follows:

[0058] The reinforcing bars are first straightened by the straightening machine 6 and then enter the receiving assembly 23 between the movable plate 232 and the fixed seat 422 from the discharge port of the straightening machine 6. After entering a certain length, the straightening machine 6 cuts the reinforcing bars. After the cut reinforcing bars enter the receiving assembly 23, the tilting cylinder 312 of the active tilting assembly 31 is activated, causing the piston rod of the tilting cylinder 312 to retract, driving the first clamp 314 to rotate upward, causing the movable plate 232 to rotate upward, thereby causing the reinforcing bars to fall out of the receiving assembly 23.

[0059] The reinforcing bar falls from the receiving assembly 23 into the guide plate 24, and slides along the inclined direction of the guide plate 24 into the unloading channel 25 formed by the two guide plates 24, and falls into the receiving guide 5 and the receiving seat 413 of the conveying mechanism 4.

[0060] The moving cylinder 433 of the moving assembly 43 is activated, and the piston rod of the moving cylinder 433 extends, causing the moving seat 425 to move on the slide rail 431 via the slider 432, thereby bringing the moving wheel 427 closer to the fixed wheel 424 and clamping the steel bar. Then, the motor 421 is activated, driving the first rotating shaft 423 to rotate, which in turn drives the fixed wheel 424 to rotate, thus conveying the steel bar.

[0061] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
