Description

Technical Field

[0001] The present application relates to the technical field of steel bar processing, and in particular to an automated steel bar braiding device. Background Art

[0002] At present, steel bars are an indispensable material in construction. The steel bars are transported to the construction site, straightened and cut by workers, and then transported to the work surface again. A large number of workers tie and install the steel bars on the work surface to meet the requirements of construction.

[0003] The existing steel bar weaving equipment is to set a straightening machine next to the steel bar weaving machine. The outlet of the straightening machine is opposite to the feed inlet of the steel bar weaving equipment. The feed inlet of the steel bar weaving machine must be located between two steel wires. Then the two steel wires rotate in a direction perpendicular to the length of the steel bars and entangle with each other to tie the steel bars, thereby weaving multiple steel bars into a steel mesh.

[0004] During the rebar weaving process, the inventor found that since the rebar must be located between two steel wires when placed in the rebar weaving equipment, a straightening machine is set next to the rebar weaving equipment. However, such a setting occupies a large area and has the defect that the efficiency of rebar weaving is affected by the discharge speed of the straightening machine. Summary of the invention

[0005] In order to reduce the floor space occupied by the equipment required for steel bar processing and to improve the efficiency of steel bar weaving, the present application provides an automated steel bar weaving equipment.

[0006] The present application provides an automated steel bar weaving device that adopts the following technical solution:

[0007] An automated steel bar weaving device comprises a frame and a straightener, wherein the straightener is fixed inside the frame, a binding assembly is arranged at one end of the top of the frame, adjacent steel bars are woven on the frame and transported in a direction away from the binding assembly, a storage rack and a lifting mechanism are arranged inside the frame, the storage rack is arranged adjacent to the straightener, the storage rack is used to store the steel bars straightened by the straightener, the lifting mechanism is located directly below the binding assembly, and the lifting mechanism is used to transport the steel bars in the storage rack to the binding assembly;

[0008] The bundling assembly includes a first wire drum and a second wire drum, the first wire drum and the second wire drum are arranged at intervals along the weaving direction of the steel bars, and the first wire drum is located behind the second wire drum along the weaving direction of the steel bars, the first wire drum includes a first steel wire and a first wire box, the second wire drum includes a second steel wire and a second wire box, the first steel wire and the second steel wire have the same output direction, the first steel wire spans the top of the first wire box and merges with the second steel wire, the first wire box and the second wire box are both rotatably connected to the frame, and the rotating shafts are both along the weaving direction of the steel bars, and the first wire box and the second wire box rotate at the same frequency.

[0009] By adopting the above technical scheme, the straightening machine stores the straightened steel bars in the storage rack without considering the weaving speed of the steel bars on the rack, and when the weaving speed on the rack is greater than the speed at which the straightening machine straightens the steel bars, the straightened steel bars in the storage rack can also meet the weaving speed of the steel bars, thereby improving the efficiency of steel bar weaving; placing the straightening machine inside the rack saves floor space and makes full use of the space under the rack; and the setting of the first wire drum and the second wire drum, in conjunction with the lifting mechanism, overcomes the disadvantage of the straightening machine being located below the rack, so that the straightened steel bars can be transported between the first wire box and the second wire box, and then cross the second wire box from the top of the second wire box and finally be located between the first steel wire and the second steel wire, and are no longer limited to being directly inserted between the first steel wire and the second steel wire from the horizontal side of the rack. Such a setting also further saves the site space required for weaving steel bars, while improving the efficiency of steel bar weaving.

[0010] Optionally, a first traction rod is hinged on the outer wall of the first wire box, a first traction ring is fixed to the end of the first traction rod away from the first wire box, a first spring is fixed between the first traction rod and the outer wall of the first wire box, the first steel wire passes through the first traction ring, and the first spring is used to provide the first traction ring with a force to always apply the first steel wire to the outer wall of the second wire box.

[0011] By adopting the above technical solution, when the straightened steel bar crosses the top of the second wire box, the first spring applies force to make the first steel wire close to the outer wall of the second wire box through the first traction rod and the first traction ring, ensuring that when the first wire box and the second wire box rotate at the same frequency, the first steel wire is always close to the outer wall of the second wire box, ensuring the winding and binding of the steel bar by the first steel wire, and cooperating with the gravity of the first steel wire itself, to achieve the double guarantee of the first steel wire close to the outer wall of the second wire box.

[0012] Optionally, a wire groove is provided on the outer wall of the second wire box, and the wire groove is provided along the outer wall at the top of the second wire box. The intersection of the wire groove and the outer wall of the second wire box is chamfered, and the first steel wire is located in the wire groove; an anti-jump component is provided on the frame, and the anti-jump component includes an outer tube, an inner rod, a pressure plate and a pressure spring. One end of the outer tube is hinged to the frame, and the hinge axis adopts bolts. The bolts are horizontally arranged and perpendicular to the weaving direction of the steel bars. The spring is located inside the outer tube, one end of the spring is fixedly connected to the outer tube, and the other end is fixedly connected to the end of the inner rod. One end of the inner rod is located inside the outer tube and the other end is fixedly connected to the pressure plate. The pressure plate is located directly above the wire groove, and the end of the pressure plate facing the first wire box is upwardly tilted.

[0013] By adopting the above technical scheme, the opening of the wire trough can further limit the first steel wire. When the second wire box rotates, the first steel wire and the second wire box can be rotated synchronously to ensure the winding and binding effect of the steel bars. When the steel bars pass over the top of the second wire box, the first steel wire will slide out of the wire trough. The chamfered setting of the wire trough facilitates the first steel wire to fall back into the wire trough better. At the same time, the anti-jump component can better ensure that the first steel wire is located in the wire trough.

[0014] Optionally, when the pressure spring is in a natural state, the distance between the pressure plate and the outer wall of the second wire box is smaller than the diameter of the first steel wire, and the pressure plate is an arc-shaped plate, and the arc-shaped concave surface is arranged facing the second wire box.

[0015] By adopting the above technical solution, when the second wire box rotates, the pressure plate limits the first steel wire, and when the first steel wire wants to slide out of the wire groove, the baffle blocks the first steel wire.

[0016] Optionally, a hydraulic cylinder is vertically arranged at the bottom of the straightener, which is fixedly connected to the frame, and a piston end of the hydraulic cylinder is fixedly connected to the straightener, and a discharge port of the straightener is arranged along a vertical direction of steel bar weaving and opposite to one end of a storage rack; the storage rack comprises a baffle and a pad, one end of the pad is fixedly connected to the frame, and the other end is cantilevered, and multiple pads are arranged at intervals along the direction of the discharge port of the straightener; the baffle is fixedly connected to the pad farthest from the straightener, and the baffle is used to block the steel bars delivered from the discharge port of the straightener; multiple groups of storage racks are arranged at intervals in the vertical direction; the cantilevered end of the pad is inclined downward in a direction away from the frame, and an opening and closing component is arranged on the frame, and the opening and closing component is used to control whether the steel bars on the storage rack roll down to the lifting mechanism.

[0017] By adopting the above technical solution, the setting of the hydraulic cylinder can adjust the height of the straightener in the vertical direction, so as to adapt to storage racks of different heights. The steel bars slide out from the discharge of the straightener and are finally blocked by the baffle. Then, they slide down according to the inclination trend of the pad and are piled up. The steel bar reserve is used to meet the weaving of steel bars of different densities, breaking the influence of the processing rate of the straightener.

[0018] Optionally, the lifting mechanism includes a mechanical arm and a lifting assembly, the lifting assembly includes a driving motor, a driving wheel, a driven wheel and a chain, the driving wheel and the driven wheel are located on the same vertical plane, the driving motor is fixedly connected to the frame, the driving wheel is looped on the rotating shaft of the driving motor, the driven wheel is rotatably connected to the frame, the rotating shaft is parallel to the rotating shaft of the driving motor, and the chain is simultaneously looped on the driving wheel and the driven wheel, a plurality of picking hooks are fixed on the chain, adjacent picking hooks are equidistantly spaced along the circumferential outer wall of the chain, the mechanical arm is located at the top of the frame, the mechanical arm is rotatably connected to the frame, and the rotating shaft is arranged parallel to the rotating shaft of the driving motor; at least two groups of lifting mechanisms are arranged, the picking hooks in the two groups of lifting mechanisms cooperate with each other to carry steel bars, and the mechanical arms in the two groups of lifting mechanisms cooperate with each other to grab the steel bars on the picking hooks and transport them to the junction of the first steel wire and the second steel wire.

[0019] By adopting the above technical solution, the driving motor drives the active wheel to rotate, and the active wheel cooperates with the chain and the driven wheel to drive the picking hook to move in a cycle. The picking hooks in the two lifting mechanisms lift a steel bar and then lift it upward to the mechanical arm. The mechanical arm transfers the steel bar to the confluence of the first steel wire and the second steel wire. The lifting assembly is located as a whole under the frame, saving space, and the mechanical arm is also located on the frame.

[0020] Optionally, the opening and closing assembly includes a partition plate and a cylinder, the cylinder body is fixed on the frame, the cylinder is vertically arranged, the cylinder piston rod is fixedly connected to the partition plate, the length direction of the partition plate is arranged along the discharge direction of the straightening machine, and the side wall of the partition plate is abutted against the cantilevered end of the pad covered by it.

[0021] By adopting the above technical solution, the cylinder controls the lifting and lowering of the partition plate, thereby controlling the steel bars on each layer of the pad to slide to the lifting component, which is practical and convenient to operate.

[0022] Optionally, the pad is arranged at an inclination, and along the discharge direction of the straightener, a plane formed by connecting all the pads in the same group is an inclined plane, and the inclination direction is arranged downwardly along a direction away from the straightener.

[0023] By adopting the above technical solution, the steel bars slide out of the straightening machine with speed, but there is a distance between adjacent pads along the discharge direction of the straightening machine, and the steel bars tend to bend downward. Setting the pads to an inclined state just conforms to the downward bending trend of the ends of the steel bars, ensuring that the steel bars can slide stably on the pads.

[0024] Optionally, along the discharging direction of the straightening machine, the lifting rates of adjacent lifting assemblies gradually become faster.

[0025] By adopting the above technical solution, since the pad is in an inclined state, the entire storage rack is in an inclined state along the discharge direction of the straightener. Through the different lifting rates of the two lifting components, the steel bars are in a horizontal state when they are lifted to the robotic arm, ensuring the stability of the robotic arm in grabbing the steel bars.

[0026] Optionally, a second traction rod is hinged on the outer wall of the second wire box, a second traction ring is fixed to the end of the second traction rod away from the second wire box, a second spring is fixed between the second traction rod and the outer wall of the second wire box, the second steel wire passes through the second traction ring, and the second spring is used to provide the second traction ring with a force to always apply force to the second steel wire close to the first steel wire.

[0027] By adopting the above technical solution, the second spring, the second traction rod and the second traction ring are arranged so that the first steel wire and the second steel wire can stably intersect, thereby ensuring the binding density of the steel bars.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The setting of the bundling assembly enables the straightened steel bars to be fed from the bottom of the bundling assembly between the first steel wire and the second steel wire, making full use of the space under the frame and saving the space required for steel bar weaving;

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The embodiment of the present application discloses an automated steel bar braiding device.

[0040] refer to Figure 1 An automated steel bar weaving device includes a frame 1, a bundling assembly 2 is arranged on the top of the frame 1, a straightener 11, a storage rack 4 and a lifting mechanism 3 are arranged below the frame 1, so as to make full use of the space below the frame 1 and reduce the site space required for steel bar weaving. The straightener 11 straightens the steel bars, the storage rack 4 stores the steel bars straightened by the straightener 11, and the lifting assembly 31 transfers the steel bars in the storage rack 4 to the bundling assembly 2, and the bundling assembly 2 binds the multiple straightened steel bars.

[0041] refer to Figure 1 In this embodiment, the frame 1 is in a triangular shape, and other shapes may also be selected. The top of the frame 1 is an inclined surface, and the bundling component 2 is located at a relatively high end of the top surface of the frame 1. After the steel bars are bundled through the bundling component 2, they slide downward along the inclined trend of the top of the frame 1 and are rolled up, which is convenient for transportation in subsequent processes.

[0042] refer to Figure 2 and Figure 3The bundling assembly 2 includes a first wire drum 21 and a second wire drum 22. Along the downward direction of the steel bars on the top of the frame 1, the first wire drum 21 is located behind the second wire drum 22 and the two are spaced apart. The first wire drum 21 includes a first wire box 212 and a first steel wire 211. The second wire drum 22 includes a second wire box 222 and a second steel wire 221. The first wire box 212 and the second wire box 222 are both rotatably connected to the frame 1, and the rotating shaft is horizontally arranged along the downward direction of the steel bars on the top of the frame 1. The method for realizing the self-rotation of the first wire box 212 relative to the frame 1 can be: fixing a first motor 13 on the frame 1, and the rotating shaft of the first motor 13 is fixedly connected to the outer wall of the first wire box 212, so as to realize the state of the first wire box 212 rotating relative to the frame 1; similarly, the method for realizing the self-rotation of the second wire box 222 relative to the frame 1 can be: fixing a second motor 14 on the frame 1, and the rotating shaft of the second motor 14 is fixedly connected to the outer wall of the second wire box 222, so as to realize the state of the second wire box 222 rotating relative to the frame 1. The first wire box 212 and the second wire box 222 rotate synchronously in the same direction.

[0043] refer to Figure 1 The conveying direction of the steel bars at the top of the frame 1 is the weaving direction of the steel bars, and the length of the frame 1 is horizontally arranged along the vertical steel bar weaving direction. A plurality of binding components 2 are arranged along the length direction of the frame 1, and adjacent binding components 2 are arranged at intervals, so that multiple steel bars are woven into a steel mesh.

[0044] refer to Figure 2 and Figure 3 , a first traction rod 5 is hinged on the outer wall of the first wire box 212, and the hinge axis is arranged along the length direction of the frame 1. A first traction ring 51 is fixed to the end of the first traction rod 5 away from the first wire box 212. The first traction rod 5 is located at the top of the first wire box 212. A first spring 52 is fixed between the first traction rod 5 and the outer wall of the first wire box 212. The first steel wire 211 is output from the discharge port of the first wire box 212, passes through the first traction ring 51 and crosses the top of the second wire box 222 to intersect with the second steel wire 221. When the first spring 52 is in a stretched state, pressure is applied to the first steel wire 211 through the first traction rod 5 and the first traction ring 51, so that the first steel wire 211 is always in close contact with the outer wall of the second wire box 222. In order to reduce the space occupied by the first spring 52, a torsion spring is used instead of the first spring 52 in this embodiment.

[0045] refer to Figure 2 and Figure 3, a second traction rod 6 is hinged on the outer wall of the second wire box 222, and the hinge axis is arranged along the length direction of the frame 1. A second traction ring 61 is fixed to the end of the second traction rod 6 away from the second wire box 222, and the second traction rod 6 is located at the bottom of the second wire box 222. A second spring 62 is fixed between the second traction rod 6 and the outer wall of the second wire box 222. The second steel wire 221 is output from the discharge port of the second wire box 222, passes through the second traction ring 61 and merges with the first steel wire 211. The arrangement of the second traction rod 6 and the second traction ring 61 can better drive the second steel wire 221 and the first steel wire 211 to entangle with each other when the second wire box 222 rotates, and the arrangement of the second spring 62 can make the second steel wire 221 as close to the first steel wire 211 as possible. In order to reduce the space occupied by the second spring 62, a torsion spring is also used in this embodiment instead of the second spring 62.

[0046] refer to Figure 3 A wire groove 2221 is opened on the outer wall of the second wire box 222, and the wire groove 2221 is opened along the direction in which the first steel wire 211 crosses the second wire box 222. The wire groove 2221 is located at the top of the second wire box 222, and the first steel wire 211 is located in the wire groove 2221. The intersection of the wire groove 2221 and the outer wall of the second wire box 222 is chamfered to facilitate the first steel wire 211 to fall back into the wire groove 2221 better.

[0047] refer to Figure 3 , an anti-jump component 7 is provided on the frame 1, and the anti-jump component 7 is located just above the second wire box 222. The anti-jump component 7 includes an outer tube 71, an inner rod 72, a pressure plate 73 and a pressure spring 74. One end of the outer tube 71 is hinged to the frame 1, and the hinge axis adopts a bolt. The bolt is horizontally arranged and perpendicular to the braiding direction of the steel bars. By rotating the bolt, the tightness of the rotation between the outer tube 71 and the frame 1 can be adjusted, thereby achieving the effect of adjusting the relative inclination angle between the outer tube 71 and the frame 1. The pressure spring 74 is located inside the outer tube 71, and the pressure One end of the spring 74 is fixedly connected to the outer tube 71, and the other end is fixedly connected to the end of the inner rod 72. One end of the inner rod 72 is located inside the outer tube 71, and the other end is fixedly connected to the pressing plate 73. The pressing plate 73 is located directly above the wire groove 2221. The end of the pressing plate 73 facing the first wire box 212 is tilted upward. The pressing plate 73 is an arc-shaped plate, and the arc-shaped concave surface is arranged directly opposite to the second wire box 222. Since the second wire box 222 will rotate relative to the frame 1, the pressing plate 73 is designed to be an arc-shaped plate to better fit the outer wall of the second wire box 222. When the pressure spring 74 is in a natural state, the distance between the pressing plate 73 and the outer wall of the second wire box 222 is less than the diameter of the first steel wire 211.

The driving motor 311 is fixedly connected to the frame 1. The driving wheel 312 is fixed on the rotating shaft of the driving motor 311. The chain 314 is simultaneously arranged on the driving wheel 312 and the driven wheel 313. A lifting hook 3141 is fixed on the chain 314. There are multiple lifting hooks 3141. Adjacent lifting hooks 3141 are arranged at intervals along the length direction of the chain 314. The lifting mechanisms 3 are arranged at intervals along the length direction of the frame 1. In this embodiment, two lifting assemblies 31 are provided, which are sufficient to stably lift a single steel bar. The robotic arm 32 is located near the second wire box 222. The robotic arm 32 is rotatably connected to the frame 1. A motor can be set between the robotic arm 32 and the frame 1 to realize a 360-degree rotation of the robotic arm 32. The robotic arm 32's own manipulator can be driven by a power cylinder to clamp and release the steel bars. The robotic arm 32 clamps and lifts the steel bars on the hook 3141, then crosses the top of the second wire box 222, and finally reaches the intersection of the second steel wire 221 and the first steel wire 211.

[0049] refer to Figure 4 Along the length direction of the frame 1, the straightener 11 and the storage rack 4 are adjacently arranged, and the discharge port of the straightener 11 is arranged opposite to the storage rack 4. A hydraulic cylinder 12 is fixed to the bottom of the straightener 11, and the hydraulic cylinder 12 is fixedly connected to the frame 1, and the piston rod of the hydraulic cylinder 12 is fixedly connected to the straightener 11, thereby realizing the lifting and lowering of the straightener 11 in the vertical direction.
