Description

Technical Field

[0001] This utility model relates to the field of anchor bolt processing technology, specifically to a continuous processing and transfer device for mining anchor bolts. Background Technology

[0002] Slotted pipe anchors are a type of anchor that provides full-length anchoring. They are made of cold-rolled steel strip and have a narrow slot along their longitudinal direction. During installation, the anchor is driven into a borehole smaller than its outer diameter. The slot is compressed and contracts, generating radial pressure on the borehole wall, causing the anchor to fit tightly against the borehole wall and achieving full-length anchoring. One end of the slotted pipe anchor is welded with a retaining ring, which secures the anchor mesh. The retaining ring and a support plate further secure the anchor mesh, connecting loose rock particles together, increasing the integrity and stability of the surrounding rock, preventing small rock fragments from falling, and acting as a surface protector.

[0003] In the manufacturing process of slotted anchor bolts, after the retaining ring welding process, the anchor bolts need to be bundled according to a specified quantity (e.g., ten bolts per bundle) for subsequent handling, storage, and use. The bundling process is usually carried out using an automatic bundling machine, with a robotic arm completing the stacking and loading.

[0004] However, after the anchor bolts are welded to the retaining rings and before automatic bundling, a transfer process is required for short-distance transfer and temporary storage. This stage typically relies on manual pushing, simple chutes, or forklifts for temporary transfer and stacking. This transfer method is essentially an intermittent, non-synchronous material flow, and its continuity depends mainly on manual intervention or operational experience. This often results in the automatic bundling equipment being in a "waiting for material" or "accumulated material" state, causing frequent interruptions in the automatic bundling process and affecting the overall production cycle. Especially in high-cycle automated production lines, this discontinuous and uncontrollable transfer state can easily become a bottleneck, affecting the efficiency of the connection between upstream and downstream processes.

[0005] Therefore, it is necessary to study a continuous processing and transfer device for mining anchor bolts. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a continuous processing and transfer device for mining anchor bolts, which can effectively solve the problems of lack of continuity in the transfer process after existing anchor bolt welding, resulting in frequent interruptions and imbalances in the subsequent automatic bundling process.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A continuous processing and transfer device for mining anchor bolts includes an anchor bolt transport device, a proximity switch, and a storage rack; The anchor bolt transport device includes a frame, a rotating shaft, a sprocket, and a ring chain; The rotating shaft is rotatably mounted on both the front and rear sides of the frame. The rotating shaft is connected to a stepper motor, which causes the rotating shaft to rotate intermittently to transport the anchor rod forward intermittently. The sprocket is fixedly sleeved on the rotating shaft; the annular chain drive is mounted on the sprocket. A load-bearing beam is fixedly mounted on the frame along the front-to-back direction, and the upper half of the ring chain moves and rests on the load-bearing beam. Several limiting components are fixedly installed at intervals on the chain to ensure that the anchor rods supported on the annular chain are arranged at intervals. The storage rack is located at the front of the anchor bolt transport device and is used to receive the anchor bolts output from the anchor bolt transport device. The proximity switch is located at the front end of the anchor bolt transport device. The proximity switch is triggered once each time the anchor bolt is pushed forward to the storage rack.

[0008] Furthermore, multiple guide frames are fixedly connected at intervals along the left-right direction on the front end face of the frame, and the ends of the guide frames extend downwards at an incline toward the storage rack. The rotating shaft is rotatably mounted on the guide frame; the proximity switch is mounted on the guide frame and located below the rotating shaft. Furthermore, it also includes a pusher mechanism, which includes a rotating rod, a pusher, a push rod, and a cylinder; The rotating rod is rotatably mounted on the guide frame and is located in front of and below the rotating shaft and the proximity switch; Multiple push claws are fixedly inserted at intervals along the left-right direction on the rotating rod; One end of the push rod is fixedly connected to the rotating rod, and the other end is hinged to the telescopic end of the cylinder; The cylinder body is hinged to the frame; When the cylinder's telescopic rod extends, the rotating rod drives the pusher claw to flip upwards, forming a buffer zone for temporarily storing the anchor rod with the guide frame.

[0009] Furthermore, the storage rack includes a base frame and a storage plate; Multiple storage plates are fixedly connected at intervals along the left and right direction on the base frame. Each storage plate has a semi-circular storage trough with an upper opening for storing and limiting the anchor rods.

[0010] Furthermore, the front and rear sides of the storage rack are provided with guide rails extending in the left and right direction; Guide wheels are rotatably mounted on both sides of the base frame, and the base frame is slidably mounted on the guide rail via the guide wheels.

[0011] Furthermore, mounting plates are fixedly connected to both sides of the chain, and the limiting component is mounted on the mounting plates.

[0012] Furthermore, the limiting component includes two limiting plates spaced apart front and rear to form a limiting range, so that the anchor rods are evenly spaced on the chain.

[0013] The beneficial effects of the above technical solution are: This invention employs an intermittent anchor bolt transport device to transport anchor bolts. Several limiting components are fixedly installed at intervals on the chain to ensure accurate spacing of the anchor bolts supported on the ring chain, guaranteeing that each transport operation inputs and outputs one anchor bolt. A proximity switch is located at the front end of the anchor bolt transport device. Each time an anchor bolt is output to the storage rack, the proximity switch is triggered, precisely controlling the transport and storage of the anchor bolts. After ten consecutive trips, the robotic arm in the subsequent bundling process uniformly grabs the anchor bolts from the storage rack, ensuring consistent quantity in each bundle. This precise control of the transport rhythm effectively avoids the lack of continuity in the post-welding transfer process of existing anchor bolts, which leads to frequent interruptions and unbalanced rhythms in the subsequent automatic bundling process. This achieves continuous transport and quantitative bundling of anchor bolts, reducing the labor intensity of personnel. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: This embodiment aims to provide a continuous processing and transfer device for mining anchor bolts, addressing the problem that the existing transfer process after anchor bolt welding lacks continuity, leading to frequent interruptions and unbalanced cycle times in the subsequent automatic bundling process.

[0017] A continuous processing and transfer device for mining anchor bolts, such as Figure 1 It includes an anchor bolt transport device, a proximity switch 7, and a storage rack 6.

[0018] Anchor bolt transport device is set after the welding ring process to transfer the anchor bolts 10 after welding ring. In the existing process of retaining ring welding, a robotic arm is usually used to grab the anchor bolts 10 and put them into the welding machine for welding. After welding is completed, they are stacked and output to the anchor bolt transport device, realizing the periodic output of anchor bolts 10 from the welding machine to the anchor bolt transport device.

[0019] like Figure 2 and Figure 3 The anchor bolt transport device includes a frame 1, a rotating shaft 2, a sprocket 3, and a ring chain 4. The frame 1 includes at least support legs and a frame fixed to the support legs, mainly used to provide an installation foundation for other components.

[0020] Three guide frames 102 are welded to the front end face of the frame 1 at intervals along the left and right direction. The ends of the guide frames 102 extend downwards towards the storage rack 6.

[0021] The rotating shaft 2 is rotatably mounted on both the front and rear sides of the frame 1. Specifically, the rotating shaft 2 at the front end is rotatably mounted on the guide frame 102. The rotating shaft 2 is connected to a stepper motor, causing it to rotate intermittently to transport the anchor rod 10 forward intermittently. The stepper motor is not shown in the attached drawings; its specific installation method and working principle are based on existing technology and will not be described further here. Under the control of the stepper motor, the intermittent forward cycle of the anchor rod transport device should be consistent with the cycle of outputting the anchor rod 10 during the welding process, ensuring that each transport by the anchor rod transport device inputs and outputs one anchor rod 10.

[0022] The sprocket 3 is fixedly mounted on the shaft 2; the annular chain 4 is driven by the sprocket 3; for ease of display, the annular chain 4 is... Figure 2 and Figure 3 The original text has been simplified; its specific structure can be found in the reference section. Figure 7 and Figure 8 .

[0023] like Figure 2 and Figure 3A load-bearing beam 101 is fixedly mounted on the frame 1 along the front-to-back direction. The upper half of the ring chain 4 moves and rests on the load-bearing beam 101, so that when the anchor rod 10 is supported on the ring chain 4, it can receive the support of the load-bearing beam 101.

[0024] like Figure 2 and Figure 3 Several limiting components 5 are fixedly installed at intervals on the chain to ensure that the anchor rods 10 supported on the ring chain 4 are arranged at intervals. Specifically, for example... Figure 7 and Figure 8 Mounting plates 9 are fixedly connected to both sides of the chain, and limiting components 5 are mounted on the mounting plates 9. The limiting components 5 include two limiting plates 501 that are spaced apart front to back to form a limiting range, which limits the front and back direction of the anchor rods 10, so that the anchor rods 10 are evenly spaced on the chain.

[0025] The proximity switch 7 is located at the front end of the anchor bolt conveying device. Whenever the anchor bolt 10 is output forward to the storage rack 6, the proximity switch 7 is triggered. The proximity switch 7 is located on the guide rack 102 and below the rotating shaft 2.

[0026] It also includes a pusher mechanism 8, such as Figure 4 The pusher mechanism 8 includes a rotating rod 801, pushers 802, a pusher rod 803, and a cylinder 804. The rotating rod 801 is rotatably mounted on the guide frame 102 and located below and in front of the rotating shaft 2 and the proximity switch 7. Three pushers 802 are fixedly mounted on the rotating rod 801 at intervals along the left and right direction. One end of the pusher rod 803 is fixedly connected to the rotating rod 801, and the other end is hinged to the telescopic end of the cylinder 804. The cylinder body of the cylinder 804 is hinged to the frame 1. The controller is connected to the cylinder 804 for control.

[0027] The storage rack 6 is located at the front of the anchor bolt transport device and is used to receive the anchor bolts 10 output from the anchor bolt transport device. Specifically, for example... Figure 6 The storage rack 6 includes a base frame 601 and a storage plate 602; multiple storage plates 602 are fixedly connected to the base frame 601 at intervals along the left and right directions, and the storage plate 602 has a semi-circular storage trough 603 with an upper opening, which is used to store and limit the anchor rod 10.

[0028] The front and rear sides of the storage rack 6 are provided with guide rails 605 extending in the left and right direction; guide wheels 604 are rotatably arranged on both sides of the base frame 601 and are slidably arranged on the guide rails 605 through the guide wheels 604, so as to facilitate the adjustment of the left and right position of the storage rack 6.

[0029] The anchor bolt transport device is equipped with a controller, which is connected to a stepper motor, a proximity switch 7, and a cylinder 804.

[0030] Initially, the pusher 802 is located below the guide frame 102, and does not affect the output of the anchor rod 10 along the guide frame 102; when the number of anchor rods 10 in the storage rack 6 reaches ten, such as Figure 5 The controller controls the operation of cylinder 804, causing the telescopic rod of cylinder 804 to extend and drive the rotating rod 801 to rotate, thereby causing the pusher 802 to flip upward and form a buffer area for temporarily storing the anchor rod 10 with the guide frame 102. This can temporarily store the anchor rod 10, improve the fault tolerance of the system, and ensure that the bundling process will not affect the overall production efficiency due to temporary misalignment. It can effectively avoid system downtime or material waste caused by error accumulation in actual operation and ensure long-term continuous operation of the system.

[0031] It is important to note that when anchor bolt 10 enters the buffer area, proximity switch 7 will be triggered normally, and the bolt will be counted in the next bundle of ten anchor bolts 10. However, when the anchor bolt enters the storage rack from the buffer area, proximity switch 7 will not be triggered. When the number of anchor bolts 10 in the storage rack 6 reaches ten, the controller should control cylinder 804 to operate after a delay. The delay period should be less than the intermittent output period of one anchor bolt transport device to ensure that the tenth anchor bolt 10 enters the storage rack 6 smoothly, while the eleventh anchor bolt is intercepted.

[0032] The storage rack 6 connects to the subsequent bundling process, which involves using a robotic arm in conjunction with pneumatic clamps to grab all the anchor rods 10 in the storage rack 6, grabbing ten anchor rods 10 at a time and bundling them together. Automatic bundling equipment is used, specifically an automatic bundling machine using nylon strapping as the binding material, which automatically and tightly binds the anchor rods 10 with nylon strapping and then uses heat-sealing adhesive to bond them together.

[0033] The anchor bolt transport device continuously and intermittently transports the anchor bolt 10. When the proximity switch 7 is triggered ten times, the pusher mechanism 8 is activated to intercept the subsequent anchor bolt 10. At this time, the controller sends a command to the robot to grab the anchor bolt 10 in the storage rack 6. After the robot clamps the anchor bolt 10 and moves it out of the storage rack 6, it sends a command to the controller, which resets the pusher mechanism 8 to its initial state and releases the intercepted anchor bolt 10 into the storage rack 6.

[0034] The robotic arm moves the anchor bolt 10 to the automatic baler for bundling. The robotic arm first inserts one end of the anchor bolt 10 into the baling area of ​​the automatic baler for bundling. After bundling one end, it withdraws, rotates 180 degrees, and then bunds the other end. After bundling, the robotic arm picks up the anchor bolt 10 and places it on a tray. The robotic arm can arrange the anchor bolts sequentially according to a set program, with layers interleaved at 90-degree angles.
