Figure 3 The "first direction" in this application is as shown in the upper and lower Figure 1 The front-to-back direction shown in the figure, the "second direction" mentioned in this application is as follows Figure 1 Left and right directions shown.

[0018] The present application embodiment provides a broken track aerial transport system, such as Figure 1As shown, the broken-rail aerial transport system 100 includes a first rail 10 and at least one transfer machine 20 . Each transfer machine 20 is arranged on the first rail 10 and can reciprocate on the first rail 10 along the extension direction of the first rail 10 .

[0019] The first rail 10 extends in a first direction and has a first end 101 and a second end 102 that are away 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 .

[0020] like Figure 5-8 As shown, the transfer machine 20 includes a mobile frame 1, a second track 2, a first drive mechanism 3, a second drive mechanism 4 and a trolley mechanism 5. The mobile frame 1 is supported on the first track 10 and is configured to move back and forth along the first direction on the first track 10. The second track 2 is movably arranged on the mobile 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 away from each other in the second direction. In the present application, the first outer end 21 is located on the left side of the second outer end 22; the second track 2 is configured to move relative to the mobile frame 1 along the second direction, and the second track 2 can carry a workpiece trolley 200 carrying a workpiece, and can carry the workpiece trolley 200 to move in the second direction. The first drive mechanism 3 is connected to the mobile frame 1 in a transmission manner, and the first drive mechanism 3 is used to drive the mobile frame 1 carrying the second track 2 to move back and forth 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 connected to the second track 2 in a transmission manner, and the second drive mechanism 4 is used to drive the second track 2 to move back and forth in the second direction relative to the mobile frame 1. The trolley mechanism 5 can be selectively connected in transmission with the workpiece trolley 200 supported on the second track 2 , and the trolley mechanism 5 is used to drive the workpiece trolley 200 to move back and forth along the second direction on the second track 2 .

[0021] like Figure 3 , 4 As shown in Figure 8, the first driving mechanism 3 includes a first motor 31 and a moving wheel 32 that is transmission-connected to the first motor 31. The moving frame 1 of the present application is transmission-connected with a plurality of moving wheels 32. The moving wheels 32 are configured to be rollingly supported on the first track 10 under the drive of the first motor 31. The moving frame 1 is movably supported on the first track 10 through the moving wheels 32. When the first motor 31 drives the moving wheels 32 to rotate, the moving frame 1 can move back and forth along the first track 10.

[0022] Continue to refer to Figure 6 - Figure 8The second driving mechanism 4 includes a second motor 41, a gear 42 transmission-connected to the second motor 41, and a rack 43 extending along the second direction. The second motor 41 is arranged on the moving frame 1, and the rack 43 is fixedly connected to the second track 2. The gear 42 transmission-connected to 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 meshing with the gear 42 drives the second track 2 to move back and forth relative to the moving frame 1 along the second direction.

[0023] The cart pusher mechanism 5 includes a third motor 51, a driving sprocket 52, a passive sprocket 53, a chain 54 and a push head 55. The driving sprocket 52 and the passive sprocket 53 are arranged on one side of the second track 2 away from each other. In the embodiment of the present application, the driving sprocket 52 is arranged close to the second outer end 22 of the second track 2, and the passive sprocket 53 is arranged close to the first outer end 21 of the second track 2. The third motor 51 is connected to the driving sprocket 52 in a transmission manner to drive the driving sprocket 52 to rotate; the chain 54 is stretched between the driving sprocket 52 and the passive sprocket 53. When the driving sprocket 52 is pulled away from the driven sprocket 53, the driving sprocket 52 is pulled away from the driven sprocket 53. When the wheel 52 rotates, the chain 54 moves in a circular motion in a direction parallel to the second track 2, and the passive sprocket 53 rotates with the active sprocket 52 under the transmission of the chain 54; the pusher head 55 is fixedly arranged on the chain 54, and the pusher head 55 extends from the chain 54 to the outside of the chain 54, and the pusher head 55 can be selectively connected to the workpiece trolley 200 on the second track 2. When the third motor 51 drives the active sprocket 52 to rotate, the circularly moving chain 54 drives the pusher head 55 to move, so that the pusher head 55 pushes the connected workpiece trolley 200 to move along the second track 2.

[0024] like Figure 1 As shown, the broken track aerial conveying system 100 is arranged in a flexible coating production line 300, and the flexible coating production line 300 includes a plurality of station processing chambers 30, which are independent of each other and distributed on at least one side of the first track 10. In the embodiment of the present application, the plurality of station processing chambers 30 are relatively distributed along both sides of the first track 10, so that the flexible coating production line 300 is distributed in a "non" shape, which reduces the floor space of the flexible coating production line 300, and is conducive to shortening the time for transferring the workpiece between each station processing chamber 30, thereby improving production efficiency.

[0025] like Figure 2As shown, each station processing chamber 30 has an entrance 6 for the workpiece trolley 200 to enter and exit, and the entrance 6 is arranged opposite to the first track 10. Each station processing chamber 30 also includes a door 7 arranged at the entrance 6, and the door 7 is configured to selectively close the entrance 6, so that when the workpiece is surface treated in the station processing chamber 30, the heat and spray generated will not leak out from the entrance 6, and the heat exchange and air pollution between the inside of the station processing chamber 30 and the outside are cut off. A fixed track 40 extending along the second direction is also arranged in each station processing chamber 30. The second track 2 in the broken track aerial conveying system 100 is configured to selectively pass through one of the entrances 6 and dock with the fixed track 40 in the corresponding station processing chamber 30, so that the workpiece trolley 200 carrying the workpiece moves from the second track 2 to the docked fixed track 40, and performs surface treatment in the station 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 of each workstation under the drive of the transfer machine 20 until the workpiece is processed.

[0026] like Figure 1 , 3 As shown in Figures 5 and 6, the workpiece trolley 200 carried on the transfer machine 20 moves along the first track 10 under the drive of the first driving mechanism 3, so that the workpiece trolley 200 can move to the entrance 6 of each station processing chamber 30. The second track 2 moves along the second direction under the drive of the second driving mechanism 4, so that when the second track 2 moves to the left, the first outer end 21 can be connected with the fixed track 40 in the station processing chamber 30 corresponding to the left side of the first track 10, and the trolley mechanism 5 pushes the workpiece trolley 200 on the second track 2 to move to the left from the second track 2 to the fixed track 40 connected; when the second track 2 moves to the right, the second outer end 22 can be connected with the fixed track 40 in the station processing chamber 30 corresponding to the right side of the first track 10, and the trolley mechanism 5 pushes the workpiece trolley 200 on the second track 2 to move to the right from the second track 2 to the fixed track 40 connected, so as to realize flexible conveying of workpieces in the production line, improve the flexibility and efficiency of conveying, and shorten the time of transferring workpieces between each station processing chamber 30.

[0027] A sensor is also provided at one end of each fixed track 40 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.

[0028] like Figure 1As shown, the flexible coating production line 300 also includes an upper piece elevator 50 and a lower piece elevator 60, which are arranged on the same side of the first track 10 and are arranged side by side with multiple workstation processing chambers 30 on this side. The upper piece elevator 50 is arranged at the first end 101 of the first track 10, and is used to provide workpieces for the empty workpiece trolley 200 on the transfer machine 20, so that the workpieces are carried to the empty workpiece trolley 200; the lower piece elevator 60 is arranged at the second end 102, and is used to move the surface-treated workpieces on the transfer machine 20 out of the broken track aerial conveying system 100.

[0029] In the present application, the broken track type aerial conveying system 100 includes two transfer machines 20. When the transfer machine 20 located at the rear side drives the workpiece trolley 200 carrying the workpiece to enter each workstation processing chamber 30 in sequence, the transfer machine 20 located at the front side loads another workpiece through the loading elevator 50, and drives the workpiece trolley 200 carrying the other workpiece to enter each workstation processing chamber 30 in sequence later than the transfer machine 20 at the rear side. The two workpieces are loaded on the broken track type aerial conveying system 100 at the same time, and move between multiple workstation processing chambers 30 one after the other, thereby improving the working efficiency of the flexible coating production line 300.

[0030] The broken track overhead conveying system 100 of the present application and the flexible coating production line 300 equipped with the broken track overhead conveying system 100 shorten the time for transferring workpieces between various processing stations, improve conveying efficiency and flexibility, and reduce the floor space of the production line.
