Description

Technical Field

[0001] This invention relates to the field of steel bar sorting equipment technology, and in particular to a sorting system and method for straight steel bar raw materials. Background Technology

[0002] Steel bar processing is one of the core and key links in building construction. To ensure the accuracy and efficiency of on-site installation, the semi-finished steel bars that have been processed in batches need to be classified and organized according to the specifications and uses of their corresponding concrete components to ensure the orderly progress of subsequent construction.

[0003] Currently, on construction sites, the transfer of straight steel bars still mainly relies on manually operated cranes, and the sorting and loading processes are also primarily done manually. This is especially true for straight steel bars with a diameter of Φ10 or less, which, due to their lower rigidity, are prone to twisting and tangling during repeated lifting operations. This often requires additional manpower for pulling and straightening, significantly increasing the labor intensity of workers and directly leading to low overall work efficiency.

Detailed Implementation

[0037] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] like Figure 1As shown, the present invention provides a sorting system for straight steel bar raw materials. The system includes a detangling and dispersing device 1, a multi-layer sorting device 2, and a control device arranged sequentially along the conveying direction. The control device is electrically connected to the detangling and dispersing device 1 and the multi-layer sorting device 2, respectively.

[0040] The untangling and dispersing device 1 includes a vibrating conveying mechanism 11 and a swinging mechanism 12 mounted on the vibrating conveying mechanism 11. The vibrating conveying mechanism 11 is used to convey straight steel bar raw materials and generate vibration. It can operate in both directions, and by reversing and then conveying in the forward direction, the ends of the straight steel bar raw materials are aligned before being conveyed to the multi-layer sorting device 2, ensuring that all steel bar ends are neat and facilitating subsequent conveying to the corresponding storage layer 22. The swinging mechanism 12 is used to drive the vibrating conveying mechanism 11 to swing back and forth along the conveying direction. The vibration and swinging work together on the straight steel bar raw materials to untangle and disperse them. By combining the two motions of vibration and swinging, the tangling between steel bars can be efficiently loosened in both the horizontal and vertical dimensions.

[0041] The multi-layer sorting device 2 includes a lifting mechanism 21 and multiple storage layers 22 arranged longitudinally at intervals. The lifting mechanism 21 drives the multiple storage layers 22 to rise and fall, so that different storage layers 22 are aligned with the far end of the vibrating conveyor mechanism 11 to receive and classify different types of straight steel bar raw materials. This achieves high-density, classified storage in vertical space, replacing traditional ground-based partitioned stacking with lifting docking, greatly saving work area. The straight steel bar raw material sorting system of this embodiment constitutes an integrated, continuously operating automated sorting production line, eliminating manual transfer and connection interruptions between multiple stages of untangling, alignment, and sorting in traditional processes, and improving the sorting efficiency of straight steel bar raw materials.

[0042] like Figure 2 As shown, the vibration conveying mechanism 11 includes a connecting frame 111 and multiple vibration conveying units 112. The connecting frame 111 extends along the conveying direction, and the multiple vibration conveying units 112 are sequentially arranged on the connecting frame 111 along the conveying direction. The modular vibration conveying units 112 are easy to disassemble, maintain and replace, and the number of vibration conveying units 112 can be flexibly adjusted according to the site size to adapt to the needs of different construction scenarios.

[0043] like Figure 3As shown, the vibrating conveying unit 112 includes a mounting frame 1121, a drive motor 1123, and multiple eccentric rollers 1122. The multiple eccentric rollers 1122 are sequentially spaced on the mounting frame 1121 along the conveying direction. The forward and reverse rotation of the eccentric rollers 1122 drives the straight steel bar raw material to move bidirectionally. The swinging mechanisms 12 are all located at the bottom end of the connecting frame 111. The drive motor 1123 is used to simultaneously drive the multiple eccentric rollers 1122 to rotate forward or in reverse simultaneously. The output end of the drive motor 1123 directly or indirectly drives the eccentric rollers 1122 on the mounting frame 1121 to rotate via a belt.

[0044] like Figure 4 As shown, the eccentric roller 1122 includes an eccentric roller shaft and a roller body, with the roller body sleeved on the eccentric roller shaft. When the eccentric roller shaft rotates, the centrifugal force generated by the eccentricity of its mass is transmitted to the roller body, causing the straight steel bar material on it to vibrate. The vibration frequency is stable and the amplitude is controllable, which can efficiently untangle and disperse the tangled steel bars without causing the steel bars to bounce and fall due to excessive vibration, thus balancing the untangling effect and the conveying stability.

[0045] like Figure 2 As shown, a support plate 113 is provided between two adjacent eccentric rollers 1122 in the vibrating conveying mechanism 11. The support plate 113 fills the gap between adjacent eccentric rollers 1122, providing continuous support for the straight steel bar raw material. This prevents the small-diameter straight steel bar raw material from getting stuck in the gap of the eccentric roller 1122, preventing equipment jamming or steel bar deformation, and ensuring smooth conveying. At the same time, the connecting frame 111 is provided with baffle plates 114 on both sides and near the end along the conveying direction. The baffle plates 114 on both sides and near the end form a protective space, effectively preventing the steel bar from falling to the side or near the end due to inertia during vibration and swaying, reducing material loss. At the same time, the baffle plate 114 on the near end is used for end alignment of the straight steel bar raw material.

[0046] like Figure 1 and Figure 2 As shown, the swing mechanism 12 includes a support frame 121 and multiple swing hydraulic cylinders 122. The connecting frame 111 of the vibration conveying mechanism 11 is hinged to the support frame 121 to form a hinge point. The multiple swing hydraulic cylinders 122 are spaced apart along the extension direction of the support frame 121. The moving end of the swing hydraulic cylinder 122 is connected to the connecting frame 111, so that the connecting frame 111 swings around the hinge point. The multiple swing hydraulic cylinders 122 work together to ensure balanced force, avoiding excessive force on one side of the connecting frame 111 and causing deformation. At the same time, it improves the stability of the swinging motion and reduces the impact of equipment operation.

[0047] like Figure 1 and Figure 5As shown, the lifting mechanism 21 of the multi-layer sorting device 2 includes a lifting mounting base 211 and multiple lifting units 212. The multiple lifting units 212 are spaced apart on the lifting mounting base 211 along the conveying direction, such as... Figure 6 As shown, multiple storage layers 22 are longitudinally spaced at the moving end of the lifting unit 212. Each storage layer 22 is connected to the moving end of multiple lifting units 212. The multiple lifting units 212 are spaced apart along the conveying direction and are driven by each other for lifting. This multi-point support and drive design ensures that the storage layer 22 is subjected to uniform force and runs smoothly during lifting, effectively avoiding tilting or jamming. The storage layer 22 is used to receive and convey straight steel bar raw materials.

[0048] like Figure 5 As shown, each storage layer 22 includes a drive unit and multiple conveying support units 221. The multiple conveying support units 221 are arranged one-to-one with multiple lifting units 212. The conveying support units 221 adopt a modular design, which not only facilitates individual maintenance or replacement, reducing overall maintenance costs, but also allows for flexible increase or decrease in the number of units according to the actual length of the storage layer 22, to adapt to the storage needs of different specifications of steel bars. The conveying support unit 221 includes a drive unit, a conveying roller 2211, a storage plate 2212, and an auxiliary support plate 2214. The conveying roller 2211 includes a support shaft and a rotating roller sleeved on the support shaft. The rotating roller rotates relative to the support shaft. The support shaft is connected to the moving end of the lifting unit 212. The storage plate 2212 is connected to the end of the support shaft of the conveying roller 2211 via a connector 2213. The auxiliary support plate 2214 is located at the far end of the storage plate 2212. The storage plate 2212 and the auxiliary support plate 2214 together form a continuous bearing surface, filling the gaps between adjacent conveying rollers 2211 and preventing the reinforcing bars from getting stuck in the gaps between the rollers. The driving component is used to synchronously drive the rotating rollers on the conveying rollers 2211 in all the conveying support units 221 on this storage layer 22 to rotate, so as to realize the lateral movement of the straight reinforcing bar raw materials in this layer.

[0049] like Figure 6 and Figure 7 As shown, the multi-layer sorting device 2 also includes a pushing mechanism 23. The pushing mechanism 23 includes a pushing mounting frame 231 and multiple pushing units 232. The multiple pushing units 232 are spaced apart on the pushing mounting frame 231. Each of the multiple pushing units 232 corresponds to an auxiliary support plate 2214 in the conveying support unit 221. The auxiliary support plate 2214 is provided with a guide groove. When it is necessary to retrieve the reinforcing bars inside the storage layer 22, the pushing mechanism 23 can be activated to move the pushing parts 2321 of the pushing unit 232 along the guide groove, pushing the inner reinforcing bars outward, which facilitates handling and solves the problem of inconvenient retrieval of deep reinforcing bars.

[0050] Example 2

[0051] This embodiment provides a method for sorting straight steel bar raw materials, using the straight steel bar raw material sorting system in Embodiment 1, and sorting is performed through the following steps:

[0052] S1. Place the straight steel bars to be sorted, which are in a tangled state, near the vibrating conveyor 11. Simultaneously, the vibrating conveyor 11 and the swing mechanism 12 are started via a control device. The drive motor 1123 of the vibrating conveyor 11 drives multiple eccentric rollers 1122 to rotate forward. While conveying the straight steel bars, the eccentric rollers 1122 generate continuous and stable vibrations due to their rotation, which are transmitted to the steel bars. At the same time, multiple swing hydraulic cylinders 122 of the swing mechanism 12 work in tandem, driving the connecting frame 111 and the entire vibrating conveyor 11 mounted on it to swing back and forth along the conveying direction. The vibration generated by the vibrating conveyor 11 and the swing mechanism 12 driving the vibrating conveyor 11 to swing back and forth, together untangling and breaking up the tangled straight steel bars.

[0053] S2. After untangling and dispersing, the control device switches the direction of the drive motor 1123, causing all eccentric rollers 1122 to rotate synchronously in the opposite direction. This drives all the straight steel bars on the vibrating conveyor 11 to retract towards their near ends. During the retraction process, the near ends of all the steel bars eventually abut against the baffle plate 114 set on the near end side of the connecting frame 111, thereby achieving automatic alignment of the near ends of the entire batch of steel bars and providing conditions for subsequent accurate classification and conveying.

[0054] S3. Based on the model (such as specifications and grade) of the batch of straight steel bars to be sorted, the control device controls the lifting mechanism 21 to operate. Specifically, it drives multiple corresponding lifting units 212 to operate synchronously, vertically lifting the target storage layer 22 where this type of steel bar needs to be stored until its bearing surface is level with the height of the far end outlet of the vibrating conveyor mechanism 11, thus completing the material receiving preparation. It should be noted that in step S1, the straight steel bars to be sorted each time are of the same specification and grade.

[0055] S4. After the storage layer 22 is positioned, the control device switches the drive motor 1123 to rotate in the opposite direction, causing the eccentric roller 1122 to resume forward rotation. The vibrating conveyor mechanism 11 smoothly conveys the entire batch of straight steel bars that have been untangled and aligned at the ends in the forward direction, transitioning them through its far-end outlet to the aligned target storage layer 22. After the steel bars fall into the storage layer 22, the drive unit of that layer can be activated to drive the rotating rollers on all the conveying rollers 2211 to rotate, and the auxiliary steel bars move laterally on the continuous bearing surface formed by the storage plate 2212 and the auxiliary support plate 2214.

[0056] S5. Repeat steps S1-S4 to automatically sort and transport different types of straight steel bars to the corresponding storage layer 22, completing the classification and storage. When the steel bars accumulated on a single storage layer 22 need to be sorted or retrieved, the pushing mechanism 23 can be activated to move the pushing parts 2321 of each pushing unit 232 along the guide groove on the auxiliary support plate 2214, pushing the inner steel bars outward for easy centralized hoisting or handling.

[0057] The method for sorting straight steel bars in this embodiment eliminates the manual transfer and connection interruptions between multiple stages of untangling, alignment, and sorting in the traditional process by using a continuously operating automated sorting line, thereby improving the sorting efficiency of straight steel bars.
