Description

Technical Field

[0001] This invention relates to the field of steel bar technology, specifically to a fully automatic intelligent unbundling machine for bundled steel bars. 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. They include plain round bars, ribbed bars, and twisted bars. Reinforcing bars for reinforced concrete refer to straight or coiled steel used for reinforcing concrete. Their shape is divided into plain round bars and deformed bars. They are delivered in two states: straight bars and coils. Plain round bars are actually small round bars and coils of ordinary low-carbon steel.

[0003] To facilitate warehousing, transportation and on-site management, steel bars are usually bundled into fixed lengths using wire or special binding ropes after production. Therefore, before processing the steel bars, it is necessary to unbundle the bundled steel bars, cut off and remove the binding parts, in order to facilitate subsequent processes such as fixed-length cutting and bending. While automatic rebar bundling and unbundling machines can bundle rebar, manual assistance is still required to calibrate the position of the binding wires. Furthermore, when encountering high-strength wires, incomplete cutting and wire residue may occur, necessitating secondary manual handling. When operators are in close contact with heavy rebars, safety accidents may occur due to wire springback or rebar tipping. Therefore, a fully automatic intelligent rebar bundling and unbundling machine is proposed to solve the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fully automatic intelligent unbundling machine for bundled steel bars. This machine can solve the problems that may occur when encountering high-strength iron wires, resulting in incomplete cutting and iron wire residue, which requires secondary manual processing. Furthermore, when operators are in close contact with heavy steel bars, safety accidents may occur due to iron wire rebound and steel bar tipping.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0017] Please see Figure 1 - Figure 9The fully automatic intelligent unbundling machine for bundled steel bars in this embodiment includes an identification guide rail 1, an identification module built into the identification guide rail 1, two sets of conveyor belts 2 at the bottom of the identification guide rail 1, a transmission belt 3 at the bottom of the identification guide rail 1, a trolley support 4 fixedly installed at the bottom of the identification guide rail 1, a ground rail trolley 5 slidably installed at the bottom of the trolley support 4, a fixed support 6 at the front of the conveyor belt 2, a gear guide rail 7 fixedly installed inside the identification guide rail 1, a clamping and cutting mechanism 8 at the front of the identification guide rail 1, and a shearing mechanism 9 at the front of the identification guide rail 1. The clamping and cutting mechanism 8 includes a sliding frame 81, a first motor 82 is fixedly installed at the bottom of the sliding frame 81, a first gear 83 is fixedly installed at the output end of the first motor 82, and the first gear 83 meshes with the gear guide rail 7; The shearing mechanism 9 includes a sliding sleeve 91, and a second electric push rod 92 is fixedly installed at the bottom of the sliding sleeve 91.

[0018] In use, bundles of steel bars are placed on two sets of conveyor belts 2. The conveyor belts 2 and the transmission belts 3 work together to smoothly transport the bundles of steel bars to the detection area of ​​the identification guide rail 1. The built-in identification module quickly identifies the binding position of the bundles of steel bars. The ground rail trolley 5 slides along the preset track through the trolley support 4 and adjusts the position of the bundles of steel bars in conjunction with the identification guide rail 1 to ensure accurate alignment in the subsequent unbundling process. Finally, the wire binding the steel bars can be cut by the clamping and cutting mechanism 8 and the shearing mechanism 9.

[0019] The clamping and cutting mechanism 8 also includes a shearing bracket 84. A first telescopic cylinder 85 is fixedly installed on the top of the inner wall of the shearing bracket 84. A rectangular sleeve 86 is movably installed on the telescopic end of the first telescopic cylinder 85. A first electric push rod 87 is fixedly installed on the top of the inner wall of the rectangular sleeve 86. Two sets of connecting rod sleeves 88 are provided inside the rectangular sleeve 86. The interior of one set of connecting rod sleeves 88 and the output end of the first electric push rod 87 are movably installed. Two sets of first scissors 89 are provided inside the rectangular sleeve 86. The two sets of connecting rod sleeves 88 and the first scissors 89 are movably installed. A connecting rod 810 is fixedly installed on the right side of the rectangular sleeve 86. A movable plate 811 is movably installed on the top of the connecting rod 810. One side of the movable plate 811 and one side of the connecting rod sleeve 88 are movably installed. The connecting rod sleeve 88 and the first scissors 89 are movably installed. A spring 16 is fitted onto the surface of the connecting rod 810. The top of the spring 16 is fixedly installed on the surface of the connecting rod 810, and the bottom of the spring 16 is fixedly installed on one side of the sliding sleeve 91.

[0020] In use, the shearing bracket 84, pushed by the first telescopic cylinder 85, rises after the head of the connecting rod 810 touches the reinforcing bar. The reinforcing bars bound by the clamping and cutting mechanism 8 are then gathered and lifted, facilitating subsequent cutting. Visual inspection can be used to determine if the binding wire has been lifted. If not, the shearing bracket 84 and the first telescopic cylinder 85 must retract. Then, the sliding frame 81 moves to the position with the bound reinforcing bar, and the shearing bracket 84 advances again, gathering and lifting the binding wire. When it is necessary to cut the binding wire, the first motor 82 drives the first gear 83 to roll along the gear guide rail 7. This allows the sliding frame 81 to move to the position of the reinforcing bar binding wire. Then, the first telescopic cylinder 85 is activated, extending downwards to push the rectangular sleeve 86 closer to the binding reinforcing bar. Subsequently, the first electric push rod 87 is activated, moving inwards towards the connecting rod sleeve 88. The inward movement of the connecting rod sleeve 88 causes the two sets of first shears 89 to engage with each other, cutting the binding wire of the reinforcing bar. After this, the first electric push rod 87 and the first telescopic cylinder 85 move in opposite directions. At this time, under the action of the spring 16, the first shears 89 and the connecting rod 810 will return to their initial state, thus allowing the subsequent reinforcing bar wire to be cut.

[0021] Please see Figure 1 - Figure 9 The shearing mechanism 9 also includes a movable sleeve 93, the inside of which and the telescopic end of the second electric push rod 92 are movably installed. The inner end of the movable sleeve 93 is movably installed with a second scissor 94, and the inner side of the movable sleeve 93 and the second scissor 94 are movably installed. A support frame 10 is provided at the bottom of the identification guide rail 1. A second telescopic cylinder 11 is fixedly installed at the bottom of the inner wall of the support frame 10. An arc-shaped block 12 is fixedly installed at the telescopic end of the second telescopic cylinder 11. The surface of the arc-shaped block 12 and the inner wall of the support frame 10 are slidably installed. A second motor 13 is fixedly installed at the bottom of the support frame 10, and a second gear 14 is fixedly installed at the output end of the second motor 13. A second toothed plate 15 is fixedly installed at the bottom of the sliding frame 81, and the second gear 14 and the second toothed plate 15 mesh with each other.

[0022] In use, the second motor 13 is started first, which drives the second gear 14 to rotate. The rotation of the second gear plate 15 causes the sliding frame 81 to adjust its position. Then, the second electric push rod 92 is started. The telescopic end of the second electric push rod 92 pushes the movable sleeve 93 to move towards the binding tape. The transmission component inside the movable sleeve 93 drives the second scissors 94 to close. When the second scissors 94 encounters the rebar and stops, it can perform a second cut on the wire binding the rebar, thus completely cutting off the wire binding the rebar. Then, the cut wire is pulled out of the rebar and stops above the transmission belt 3. Then, the reverse steps can be repeated to remove the wire that has fallen on the transmission belt 3. Then, the vision recognition continues to scan for binding wire and stops, repeating all the previous actions.

[0023] The working principle of the above embodiments is as follows: When in use, the operator starts the conveyor belt 2 and the transmission belt 3 to run, and then smoothly transports the bundled steel bars to the detection area of ​​the identification guide rail 1. The identification module built into the identification guide rail 1 is activated to quickly collect information such as the binding position of the steel bar bundle, the number of binding wires and the specifications of the steel bars. Then the first motor 82 is started. The output end of the first motor 82 drives the first gear 83 to roll along the gear guide rail 7 inside the identification guide rail 1, thereby driving the sliding frame 81 and the entire clamping and cutting mechanism 8 to move directly above the positioned steel bar binding wire. Subsequently, the shearing bracket 84 moves toward the rebar bundle under the push of the first telescopic cylinder 85. After the head of the connecting rod 810 contacts the rebar, the first telescopic cylinder 85 continues to apply force to make the connecting rod 810 drive the movable plate 811 to rise, gather the binding wires of the rebar bundle and lift them upward. At this time, the recognition module starts vision recognition again to determine whether the binding wires have been effectively lifted. If they have not been lifted, the first telescopic cylinder 85 retracts and drives the shearing bracket 84 back to the initial position. At the same time, the first motor 82 drives the sliding frame 81 to fine-tune its position until the vision recognition confirms that the binding wires have been gathered and lifted. After confirming that the wire has been lifted, the first telescopic cylinder 85 extends downwards. The telescopic end of the first telescopic cylinder 85 pushes the rectangular sleeve 86 closer to the binding wire. Then, the first electric push rod 87 is activated. The telescopic end of the first electric push rod 87 pushes the connecting rod sleeve 88 to move inwards. The two sets of connecting rod sleeves 88 respectively drive the two sets of first scissors 89 inside the rectangular sleeve 86 to mesh with each other, thereby cutting the binding wire once. After the cutting is completed, the first electric push rod 87 extends in the opposite direction, the first telescopic cylinder 85 retracts upwards, and at the same time, the spring 16 sleeved on the surface of the connecting rod 810 releases elastic potential energy, causing the first scissors 89, the rectangular sleeve 86 and the connecting rod 810 to return to their initial positions, waiting for the second cutting signal. Then, the second motor 13 is started. The output end of the second motor 13 drives the second gear 14 to rotate. At this time, under the action of the second tooth plate 15, the sliding frame 81 can be driven to make a small range of fine adjustment to ensure that the wire remnant after the first cut is still within the working range of the second shears 94. At the same time, the second telescopic cylinder 11 is started. The second telescopic cylinder 11 pushes the arc block 12 to slide upward along the inner wall of the support frame 10 until the surface of the arc block 12 is in close contact with the bottom of the steel bundle, so as to achieve stable support for the steel bundle and prevent the steel bundle from shifting during the second cut. Then, the second electric push rod 92 is activated. The telescopic end of the second electric push rod 92 pushes the movable sleeve 93 to move towards the remaining section of the binding wire. The transmission component inside the movable sleeve 93 moves with the movable sleeve 93, thereby driving the two sets of second shears 94 from the open state to the closed state. When the second shears 94 contact the reinforcing bar and are blocked, the second electric push rod 92 stops telescopicating. The second shears 94 complete the secondary cutting of the remaining section of the wire, ensuring that the binding wire is completely cut off. After the second shearing is completed, the second electric push rod 92 extends and retracts in the opposite direction, driving the movable sleeve 93 and the second scissors 94 back to the initial position. The second telescopic cylinder 11 retracts, and the arc block 12 slides down the inner wall of the support frame 10 to reset. The second motor 13 rotates in the opposite direction, driving the sliding frame 81 back to the initial working position. Then, the cut binding wire is pulled away from the steel bar bundle and transported to the top of the transmission belt 3. The wire falls onto the transmission belt 3, and the transmission belt 3 rotates to transport the wire waste to the designated collection box.

[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
