[0002] In the automotive production process, pallets containing seats are handled and transported. The conveying speed of these pallets at the transfer point significantly impacts the entire seat production line. To accelerate the process and reduce time, multiple sets of pallets are typically transported simultaneously at the transfer point (e.g., via elevators). Ensuring the accurate quantity of pallets transported at each transfer is crucial; failure to do so can have the opposite effect, affecting conveying speed and, more seriously, leading to incorrect pallet sequence and disrupting production. Therefore, there is an urgent need for an automotive seat production line transportation system capable of delivering the accurate number of pallets to the transfer point. Summary of the Invention

[0029] The specific electrical principles are as follows: Figure 4 As shown, taking the transfer roller conveyor 1 at the transfer point as an example, which needs to transport 2 pallets each time, there are 4 operating modes.

[0030] Method 1: There are two or more pallets on waiting roller conveyor 2. Pallet 20 is blocked by waiting roller conveyor stopper 6. Both the second cut-off detection switch 8 and the waiting station detection switch 17 have signals. Pallet 21 is blocked by waiting roller conveyor stopper 9. Both the second cut-off detection switch 11 and the waiting station detection switch 18 have signals. Pallet 22 is blocked by waiting roller conveyor stopper 12. Both the second cut-off detection switch 14 and the waiting station detection switch 19 have signals. There are no pallets on transfer roller conveyor 1. The first release detection switch 4 has a signal. The waiting transfer station detection switches 15 and 16 have no signals. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the PLC master controller 23 determines that two seat pallets need to be transferred from waiting roller conveyor 2 to transfer roller conveyor 1. Waiting roller conveyor stoppers 6 and 9 are opened, and the second release detection switch... Signals 7 and 10 are received. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the transfer roller 1 and the waiting roller 2 will operate, and pallets 20 and 21 will be transported to the transfer roller stop 3. However, pallet 22 will be blocked because the waiting roller stop 12 has not been opened. At this time, the waiting transfer position detection switches 15 and 16 will receive signals, and the pallet transport is completed. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the waiting roller stop 6 and 9 will be closed. At this time, there are 2 pallets at the transfer roller 1, which meets the transfer requirements. The transfer roller stop 3 will be opened, and the first release detection switch 4 will receive signals. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the transfer roller 1 will operate, transporting 2 seat pallets to the seat line, and the process will end.

[0031] Method 2: There are two or more pallets on waiting roller conveyor 2. Pallet 20 on waiting roller conveyor 2 is blocked by waiting roller conveyor stopper 6. Both the second cut-off detection switch 8 and the waiting station detection switch 17 have signals. Pallet 21 is blocked by waiting roller conveyor stopper 9.

The first release detection switch 4 has a signal, the waiting transfer position detection switch 15 has a signal, and the waiting transfer position detection switch 16 has no signal. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the PLC master controller 23 determines that one seat pallet needs to be transferred from waiting roller conveyor 2 to transfer roller conveyor 1. Waiting roller conveyor stopper 6... When the second release detection switch 7 is open, a signal is received. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, transfer rollers 1 and 2 start operating, and pallet 20 is transported to transfer roller stop 3. Pallets 21 and 22 are blocked because waiting roller stops 9 and 12 have not opened. At this time, waiting transfer position detection switches 15 and 16 receive signals, and pallet transport is completed. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, waiting roller stop 6 closes. At this time, there are 2 pallets at transfer roller 1, which meets the transfer requirements. Transfer roller stop 3 opens, and the first release detection switch 4 receives a signal. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, transfer roller 1 starts operating, transporting 2 seat pallets to the seat line, and the process ends.

The first release detection switch 4 has a signal, while the waiting transfer station detection switches 15 and 16 have no signals. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, the PLC master controller 23 determines that the tray needs to be moved from the waiting roller conveyor. 2. One seat tray is fed to transfer roller 1. The roller stop 6 is opened. When the stop is fully open, the limit switch 7 sends a signal. It is necessary to check whether the input module of the field slave controller 24 has received these signals. After the conditions are met, transfer roller 1 and waiting roller 2 start running. The tray 20 will be transported to transfer roller stop 3. At this time, the waiting transfer position detection switches 15 and 16 send signals. The tray transport is completed. It is necessary to check whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the roller stop 6 is closed. At this time, there is one tray at transfer roller 1, which does not meet the transfer requirements. It waits for other trays to arrive until the process ends.

[0033] Method 4: There is one tray on waiting roller conveyor 2. Tray 20 on waiting roller conveyor 2 is blocked by waiting roller conveyor stopper 6. The second cutoff detection switch 8 and waiting station detection switch 17 both have signals. There are no trays at waiting roller conveyor stops 9 and 12.

The first release detection switch 4 has a signal, the waiting transfer position detection switch 15 has a signal, and the waiting transfer position detection switch 16 does not have a signal. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. After the conditions are met, the PLC master controller 23 determines that one seat tray needs to be transferred from waiting roller conveyor 2 to transfer roller conveyor 1. The waiting roller conveyor stopper 6 is opened. When the second release detection switch 7 receives a signal, it is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, the transfer rollers 1 and 2 start operating, and the pallet 20 is transported to the transfer roller stop 3. At this time, the waiting transfer position detection switches 15 and 16 receive signals, and the pallet transport is completed. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, wait for the roller stop 6 to close. At this time, there are 2 pallets at the transfer roller 1, which meets the transfer requirements. The transfer roller stop 3 opens, and the first release detection switch 4 receives a signal. It is necessary to determine whether the input module of the field slave controller 24 has received these signals. Once the conditions are met, the transfer roller 1 starts operating, transporting 2 seat pallets to the seat line, and the process ends.
