Detailed Implementation

[0026] To explain in detail the technical content, structural features, achieved objectives and effects of this application, the technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings.

[0027] The terms "front," "rear," "left," and "right" as used in this application refer to... Figure 1 The terms "front," "back," "left," and "right" as shown in the appendix, and "upper" and "lower" as used in this application, are in accordance with the appendix. Figure 3 As shown above and below, the "first direction" described in this application is in accordance with the appendix. Figure 1 The front-back direction shown in the appendix, the "second direction" mentioned in this application, refers to the direction indicated in the appendix. Figure 1 The left and right directions are shown.

[0028] This application provides a broken-rail aerial transport system, such as... Figure 1 As shown, the broken-rail aerial transport system 100 includes a first track 10 and at least one transfer machine 20. Each transfer machine 20 is arranged on the first track 10 and can reciprocate along the extension direction of the first track 10.

[0029] The first track 10 extends along a first direction and has a first end 101 and a second end 102 that are far apart from each other in the first direction, and each transfer machine 20 moves back and forth between the first end 101 and the second end 102.

[0030] like Figure 5-8 As shown, the transfer machine 20 includes a movable frame 1, a second track 2, a first drive mechanism 3, a second drive mechanism 4, and a trolley mechanism 5. The movable frame 1 is supported on the first track 10 and configured to move back and forth along a first direction on the first track 10. The second track 2 is movably arranged on the movable frame 1 and extends along a second direction perpendicular to the first direction. The second track 2 has a first outer end 21 and a second outer end 22 that are spaced apart from each other in the second direction. In this application, the first outer end 21 is located to the left of the second outer end 22. The second track 2 is configured to move relative to the movable frame 1 along the second direction. The second track 2 can carry a workpiece trolley 200 carrying a workpiece and can move the workpiece trolley 200 in the second direction. The first drive mechanism 3 is driven to the movable frame 1 and is used to drive the movable frame 1 carrying the second track 2 to reciprocate along the first track 10 and between the first end 101 and the second end 102 of the first track 10. The second drive mechanism 4 is driven to the second track 2 and is used to drive the second track 2 to reciprocate relative to the movable frame 1 in the second direction. The trolley mechanism 5 can be selectively connected to the workpiece carriage 200 supported on the second track 2, and the trolley mechanism 5 is used to drive the workpiece carriage 200 to move back and forth on the second track 2 in the second direction.

[0031] like Figure 3 , 4 As shown in Figure 8, the first drive mechanism 3 includes a first motor 31 and a movable wheel 32 that is driven by the first motor 31. The movable frame 1 of this application is driven by a plurality of movable wheels 32. The movable wheels 32 are configured to roll and support on the first track 10 under the drive of the first motor 31. The movable frame 1 is movably supported on the first track 10 by the movable wheels 32. When the first motor 31 drives the movable wheels 32 to rotate, the movable frame 1 can move back and forth along the first track 10.

[0032] Continue to refer to Figure 6 - Figure 8 The second drive mechanism 4 includes a second motor 41, a gear 42 that is driven by the second motor 41, and a rack 43 that extends along the second direction. The second motor 41 is mounted on the movable frame 1, and the rack 43 is fixedly connected to the second track 2. The gear 42 that is driven by the second motor 41 is configured to mesh with the rack 43. When the gear 42 rotates under the drive of the second motor 41, the rack 43 that meshes with the gear 42 drives the second track 2 to move back and forth relative to the movable frame 1 along the second direction.

[0033] The trolley mechanism 5 includes a third motor 51, a drive sprocket 52, a driven sprocket 53, a chain 54, and a pusher head 55. The drive sprocket 52 and the driven sprocket 53 are disposed on one side of the second track 2, away from each other. In this embodiment, the drive sprocket 52 is disposed near the second outer end 22 of the second track 2, and the driven sprocket 53 is disposed near the first outer end 21 of the second track 2. The third motor 51 is connected to the drive sprocket 52 to drive the drive sprocket 52 to rotate. The chain 54 is tensioned between the drive sprocket 52 and the driven sprocket 53. When the drive sprocket... When wheel 52 rotates, chain 54 moves cyclically in a direction parallel to the second track 2. Driven sprocket 53 rotates with drive sprocket 52 under the drive of chain 54. Push head 55 is fixedly mounted on chain 54 and extends from chain 54 to the outside of chain 54. Push head 55 can be selectively connected to workpiece carriage 200 on the second track 2. When third motor 51 drives drive sprocket 52 to rotate, the cyclically moving chain 54 drives push head 55 to move, so that push head 55 pushes connected workpiece carriage 200 to move along the second track 2.

[0034] like Figure 1 As shown, the broken-rail aerial conveying system 100 is installed within a flexible coating production line 300. The flexible coating production line 300 includes multiple processing chambers 30, which are independent of each other and distributed on at least one side of a first track 10. In this embodiment, the multiple processing chambers 30 are distributed opposite each other along both sides of the first track 10, resulting in a "non-U" shaped distribution of the flexible coating production line 300. This reduces the floor space occupied by the flexible coating production line 300 and helps to shorten the time for workpieces to transfer between the various processing chambers 30, thereby improving production efficiency.

[0035] like Figure 2As shown, each processing chamber 30 has an entrance 6 for the workpiece trolley 200 to enter and exit. The entrance 6 is directly opposite the first track 10. Each processing chamber 30 also includes a door 7 at the entrance 6, configured to selectively close the entrance 6. This prevents heat and spray generated during surface treatment of the workpiece within the processing chamber 30 from leaking out from the entrance 6, thus isolating the interior of the processing chamber 30 from the outside environment and preventing air pollution. Each processing chamber 30 also has a fixed track 40 extending along a second direction. The second track 2 in the broken-rail aerial conveyor system 100 is configured to selectively pass through one of the entrances 6 and connect with the fixed track 40 in the corresponding processing chamber 30. This allows the workpiece trolley 200 carrying the workpiece to move from the second track 2 to the connected fixed track 40 for surface treatment within the processing chamber 30. In order to meet the coating requirements of different workpieces, the second track 2 carries the workpiece and is flexibly transferred between the processing chambers 30 under the drive of the transfer machine 20 until the workpiece is processed.

[0036] like Figure 1 , 3 As shown in Figure 5, the workpiece trolley 200, carried on the transfer machine 20, moves along the first track 10 under the drive of the first drive mechanism 3, allowing the workpiece trolley 200 to move to the entrance 6 of each workstation processing chamber 30. The second track 2 moves along a second direction under the drive of the second drive mechanism 4, so that when the second track 2 moves to the left, the first outer end 21 can be aligned with the fixed track 40 in the corresponding workstation processing chamber 30 on the left side of the first track 10, and at the same time, the pusher mechanism 5 pushes the workpiece trolley 200 on the second track 2 from the second track 2 to the left onto the aligned fixed track 40; when the second track 2 moves to the right, the second outer end 22 can be aligned with the fixed track 40 in the corresponding workstation processing chamber 30 on the right side of the first track 10, and at the same time, the pusher mechanism 5 pushes the workpiece trolley 200 on the second track 2 from the second track 2 to the right onto the aligned fixed track 40, realizing flexible workpiece transportation within the production line, improving the flexibility and efficiency of transportation, and shortening the time for workpiece transfer between each workstation processing chamber 30.

[0037] Each fixed track 40 is also equipped with a sensor at one end away from the first track 10. The sensor is configured to transmit a door closing signal to the control system when triggered by the workpiece trolley. The control system controls the door 7 corresponding to the fixed track 40 to close based on the door closing signal.

[0038] like Figure 1As shown, the flexible coating production line 300 also includes an upper part elevator 50 and a lower part elevator 60. The upper part elevator 50 and the lower part elevator 60 are located on the same side of the first track 10 and are arranged side by side with multiple workstations 30 on that side. The upper part elevator 50 is located at the first end 101 of the first track 10 and is used to provide workpieces to the empty workpiece trolley 200 on the transfer machine 20, so that the workpieces are carried to the empty workpiece trolley 200. The lower part elevator 60 is located at the second end 102 and is used to remove the surface-treated workpieces from the transfer machine 20 out of the broken rail aerial conveying system 100.

[0039] In this application, the rail-break aerial conveyor system 100 includes two transfer machines 20. When the rear transfer machine 20 drives the workpiece trolley 200 carrying the workpiece to enter each workstation processing chamber 30 in sequence, the front transfer machine 20 loads another workpiece through the upper hoist 50. The workpiece trolley 20 carrying the other workpiece is driven by the rear transfer machine 20 to enter each workstation processing chamber 30 in sequence. The two workpieces are loaded on the rail-break aerial conveyor system 100 at the same time and move one after the other between multiple workstation processing chambers 30, thereby improving the working efficiency of the flexible coating production line 300.

[0040] The broken-rail aerial conveyor system 100 and the flexible coating production line 300 equipped with the broken-rail aerial conveyor system 100 of this application shorten the time for transferring workpieces between various processing stations, improve conveying efficiency and flexibility, and reduce the floor space of the production line.

[0041] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be construed as limiting the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit of this application should be included within the scope of protection of this application.
