Description

Technical Field

[0001] This utility model relates to an aerial transport line in a factory, specifically belonging to the field of aerial automated transport technology. Background Technology

[0002] Traditional aerial work platforms (such as aerial work vehicles, suspended platforms, and tracked trolleys) generally rely on ground operation or manual climbing for maintenance, which presents the following problems.

[0003] 1. Safety hazards: Personnel need to perform maintenance at heights or outside equipment, which can easily lead to accidents due to falls or operational errors.

[0004] 2. Low maintenance efficiency: Equipment failure requires production interruption, and high-altitude operations are time-consuming, affecting production line continuity. Space utilization is also low.

[0005] 3. The complex layout of ground equipment poses a risk of interference with the main equipment, resulting in wasted factory space.

[0006] The existing conventional method of combining transport rails with articulated robots occupies bottom space, and the transport line needs to be shut down when a single main device is being maintained. In a work environment with multiple devices operating in parallel and having a large production capacity, the maintenance of a single device affects the operation of other devices, thus reducing the utilization rate of the equipment.

[0007] To address the aforementioned issues, there is an urgent need for an aerial transport line that can achieve automated high-altitude handling while also reducing safety risks and improving maintenance efficiency through bottom maintenance access. Summary of the Invention

[0008] This invention addresses the shortcomings of existing high-altitude material handling technology in factories by providing a high-efficiency, safe, and reliable high-altitude material handling line for factories.

[0009] The high-altitude material handling line for factories of this utility model adopts the following technical solution:

[0010] This aerial work platform includes an elevated column bridge, a sliding plate, a robot, an loading conveyor roller conveyor, and an unloading conveyor roller conveyor. Linear guide rails are installed on the elevated column bridge. The sliding plate is mounted on the linear guide rails via sliders and connected to a moving mechanism, which is located on the elevated column bridge. The robot is mounted on the sliding plate, and a gripper is installed at its end. The loading and unloading conveyor roller conveyors are located on opposite sides of the elevated column bridge. The gripper assembly is responsible for clamping and releasing the workpieces.

[0011] The elevated column bridge consists of column assemblies and a ceiling track. The ceiling track is mounted on at least two sets of column assemblies, and the linear guide rail and moving mechanism are mounted on the ceiling track. Each column assembly is portal-shaped, consisting of two columns and a cross brace. The cross brace connects to the two columns, and the ceiling track connects to the cross brace. A base plate is provided at the bottom of each column, with leveling screws between the base plate and the column. Bolts (for fixing to the foundation) are provided on the base plate, and the verticality of the entire transport line is roughly adjusted using the leveling screws. The ceiling track is composed of multiple sections spliced ​​together, with adjacent sections connected to the column assemblies and secured with screws. Leveling bolts are provided on the ceiling track for fine-tuning its level. The ceiling track includes a first ceiling track and a second ceiling track. Slides are mounted on both the first and second ceiling tracks via linear guide rails, and robots are arranged back-to-back on the slides of the first and second ceiling tracks. An intermediate safety platform is provided between the first and second ceiling tracks.

[0012] The moving mechanism is a rack and pinion transmission mechanism, with the rack mounted on the overhead rail of the elevated bridge and the gear mounted on the drive motor shaft of the robot. The robot's drive motor drives the rack and pinion transmission mechanism, causing the slide to move linearly on the elevated bridge (overhead rail).

[0013] Both the front and rear of the slide are equipped with a traveling platform, which is equipped with a workpiece positioning fixture to store and transport workpieces and blanks. The traveling platform moves together with the slide.

[0014] The elevated bridge is equipped with high-level platforms, with a straight ladder beneath each platform. A safety door with a safety lock is located on the outside of the ladder. Mesh grating is installed on the high-level platforms. The platforms are inclined, with drainage outlets at their lower points connected to drainage pipes. A drainage valve is located at the end of the drainage pipes for centralized, periodic drainage.

[0015] A maintenance platform is provided on the elevated bridge.

[0016] The feeding conveyor roller conveyor is equipped with a feeding position, and the feeding position is equipped with a workpiece positioning device and a material detection device.

[0017] The unloading conveyor roller conveyor is equipped with an unloading position to transport the finished workpiece to the next process.

[0018] The moving mechanism drives the slide and the robot on it to move between the loading and unloading conveyor rollers. After the workpiece is conveyed to its position by the loading conveyor rollers, the robot moves to the loading position, grabs the workpiece with its gripper and places it onto the slide. The robot then moves with the slide to the unloading position and places the workpiece onto the unloading conveyor roller. The unloading conveyor roller detects the material and starts to transport it to the next process.

[0019] The above-mentioned device enables high-altitude material handling. It has the following advantages:

[0020] 1. Bottom maintenance and upper handling are separated into two layers. The handling robot is isolated at a high altitude on the upper level by column components, overhead rails, high-level treads, intermediate safety platform and maintenance platform, while the lower robot is responsible for workpiece handling. Equipment maintenance and operation personnel are isolated below the platform, ensuring that daily maintenance can be carried out without stopping the line, thereby improving equipment utilization.

[0021] 2. It has a large grasping range. The layout of the robot and the overhead track can be slightly expanded to expand the robot's grasping range, making it compatible with loading and unloading of more equipment. Multiple devices can be used within the robot's grasping cycle range. Attached Figure Description

[0033] This utility model relates to an aerial material handling line for automated material handling at heights within a factory. Its structure is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The system includes an elevated column bridge, a sliding plate, a robot 6, a loading conveyor roller 15, and a discharging conveyor roller 17. Linear guide rails are installed on the elevated column bridge. The sliding plate 5 is mounted on the linear guide rails 29 via sliders and is connected to a moving mechanism, which is located on the elevated column bridge. The robot 6 is mounted on the sliding plate 5, and a gripper 18 is installed at the end of the robot, responsible for clamping and releasing workpieces. This transport line uses the high-altitude, downward-reaching articulated robot 6 to transfer and transport goods. A safety platform is installed at the bottom, with a maintenance area, allowing personnel to perform equipment maintenance and repairs in a low-risk area on the ground. This system is suitable for industrial scenarios requiring high-altitude operations, such as chemical, power, warehousing and logistics, and casting industries.

[0034] See Figure 6 The column 1 is installed on the base plate 28, which is fixed to the foundation by chemical bolts 27. A leveling bolt 25 is installed between the base plate 28 and the column 1. The leveling bolt 25 is used for coarse leveling of the entire transport line. The leveling bolt 25 is equipped with an internal hex screw 24 and a lock nut 26 for locking and connecting after leveling.

[0035] A crossbeam 3 is installed above the two columns 1, forming a portal-shaped column assembly. Multiple sets of column assemblies are arranged according to a predetermined route. A first overhead rail 4 and a second overhead rail 9 are installed on the crossbeam 3 of each column assembly, forming an elevated column bridge. The overhead rail is composed of multiple sections spliced ​​together, with adjacent sections connected to the crossbeam 3 and secured with screws. The outer sides of the crossbeam 3 extend beyond the columns 1 by a certain length. High-level platforms 11 are installed on both sides of the crossbeam 3 where the platforms extend beyond the columns 1, and these platforms are adjacent to the first overhead rail 4 and the second overhead rail 9, respectively. (See also...) Figure 7 The crossbeam 3 is provided with leveling bolts 22 and fastening bolts 23 between the first rail 4 and the second rail 9. The first rail 4 and the second rail 9 are finely leveled by leveling bolts 22, and the rails are fixedly connected to the crossbeam 3 by fastening bolts 23 after leveling.

[0036] See Figure 7 Linear guide rails 29 are installed on both the first track 4 and the second track 9, and the linear guide rails 29 are fixedly connected to the overhead track with screws. A slide plate 5 is mounted on the linear guide rail 29 via a slider 30, and the slide plate 5 is fixedly connected to the slider 30 with screws. A robot 6 is mounted on the slide plate 5, and the robot 6 is bolted to the slide plate 5. The end of the robot 6 is bolted to a gripper 18. The robot is a downward-reaching articulated robot, and the gripper 18 is installed at the end of the robot's six axes. The gripper can be adapted according to the characteristics of the workpiece. The robots on the slide plates of the first track 4 and the second track 9 are arranged back-to-back. A gear and rack transmission mechanism is also provided between the overhead track (first track 4 or second track 9) and the slide plate 5. The rack 31 is mounted on the overhead track with screws, the gear 32 is connected to the power output end of the reducer 33, and the power input end of the reducer 33 is connected to the robot's seventh-axis servo motor 34. The reducer 33 is mounted on the slide plate 5 via a reducer mounting plate 35. By controlling the rotation of the robot's seventh-axis servo motor 34, the gear 32 is ultimately driven to rotate. The gear 32 meshes with the rack 31, converting the rotational motion into linear motion, thereby enabling the robot 6 to perform linear motion on the overhead track 4 and overhead track 2 line 9.

[0037] See Figure 3 The front and rear sides of the slide plate 5 are respectively bolted to a front follower platform 8 and a rear follower platform 7. The bottom of the front follower platform 8 and the rear follower platform 7 are equipped with sliders, which are mounted on the linear guide rail 29 and move together with the slide plate. The front follower platform 8 and the rear follower platform 7 can be equipped with workpiece positioning fixtures for storing and transporting workpieces and blanks.

[0038] See Figure 3 An intermediate safety platform 10 is provided between the first track 4 and the second track 9, and the intermediate safety platform 10 is connected to the first track 4 and the second track 9 by screws. The first track 4, the second track 9, the intermediate safety platform 10 and the high-level platform 11 form a high-level platform, which is supported on the ground by columns 1 and beams 3. A maintenance platform 14 is also provided on the beams 3, adjacent to the overhead track 4. A straight ladder 19 is provided at one end of the maintenance platform 14, and a safety door 20 is provided at the bottom of the straight ladder 19. The safety door 20 is equipped with a safety lock, and personnel can enter the upper robot handling space through the straight ladder 19.

[0039] See Figure 8 The high-rise platform 11 is higher on the outside and lower on the inside, with the side of the ceiling track being lower. There is a drain outlet at the lower point, which is connected to the drainage pipe 21 via a flexible hose. The end of the drainage pipe 21 is equipped with a ball valve, which allows for centralized and periodic drainage. A mesh grating 12 is laid on the high-rise platform 11.

[0040] See Figure 1 , Figure 2 and Figure 3On both sides of the elevated bridge, there are loading conveyor rollers 15 and unloading conveyor rollers 17. Loading conveyor rollers 15 are responsible for transporting workpiece blanks and have two loading positions, each equipped with a workpiece positioning device and a material presence detection device. Unloading conveyor rollers 17 are responsible for transporting finished workpieces and have two unloading positions, transporting the finished workpieces to the next process. The two loading positions correspond to one side of the first track 4 and the second track 9, respectively, and the two unloading positions correspond to the other side of the first track 4 and the second track 9, respectively. Robots 6 on the first track 4 and the second track 9 perform material handling on the loading conveyor rollers 15 and the unloading conveyor rollers 17. Safety fences 16 are installed on the loading conveyor rollers 15 and the unloading conveyor rollers 17 within the gripping range of the robots 6 to isolate the robot's working space and ensure compliance with safe operating procedures.

[0041] The process by which the above-mentioned device completes high-altitude material handling within the factory is described below.

[0042] The first track 4 and the second track 9 are responsible for the automatic handling of materials on both sides, and their operation process is the same.

[0043] The workpiece is conveyed to the loading position of the loading conveyor roller 15. When the loading position is detected to have material, a signal is sent to robot 6. After robot 6 finishes its current work, the robot's seventh-axis servo motor 34 starts, and through gear and rack transmission, the slide plate 5 moves to the front of the loading conveyor roller 15. The gripper 18 picks up the workpiece, and robot 6 adjusts its posture to place the workpiece on the front follower table 8. The slide plate 5, along with robot 6, the front follower table 8, and the rear follower table 7, moves to the unloading position. Robot 6's gripper 18 picks up the workpiece, and then robot 6 moves to the unloading conveyor roller 17. After detecting the presence of material, the unloading conveyor roller 17 starts, moving the workpiece to the next station.

[0044] Operators perform routine maintenance below the overhead rail. When robot 6 requires repair, the operator opens safety door 20, at which point the safety lock opens, the sliding plate 5 stops running, and the operator ascends the elevator 19 to the maintenance platform 14, then walks along the mesh grille 12 on the upper platform 11. This process enables high-altitude material handling and maintenance within the factory, thus separating equipment transport from routine maintenance at the lower levels.
