[0022] Meanwhile, between the discharge end of the loading conveyor line and the feed end of the unloading conveyor line, which are located at the same end (the end close to the processing station), a loading line lateral transfer mechanism 17 and an unloading line lateral transfer mechanism 18 are arranged in parallel in sequence. Moreover, several bin transfer brackets 8 are provided on the loading conveyor line, the loading line lateral transfer mechanism 17, the unloading line lateral transfer mechanism 18, and the unloading conveyor line, and the bins for containing workpieces are placed on the bin transfer brackets 8. A bracket stopper 27 is arranged between the loading line lateral transfer mechanism 17 and the discharge end of the loading conveyor line to control the number of bins entering the loading line lateral transfer mechanism 17 and the unloading line lateral transfer mechanism 18 by means of the blocking of the bracket stopper 27. Forklift blockers 15 for preventing the forklift from hitting the transfer track are respectively arranged at the loading port of the loading port transfer mechanism 14 and the unloading port at the end of the unloading conveyor line. In addition, above the loading line lateral transfer mechanism 17 and the unloading line lateral transfer mechanism 18, a bin cover hanging bracket 20 is provided.

[0023] The structures of the loading line horizontal transfer mechanism 17 and the unloading line horizontal transfer mechanism 18 arranged in parallel are the same, and both include a horizontal transfer lifting frame 28. Between the horizontal transfer lifting frame 28 and the fixed frame of the track support 1, several groups of vertically arranged lifting frame jacking cylinders 29 are provided. On the upper side of the horizontal transfer lifting frame 28, horizontal transfer brackets 30 are respectively and fixedly arranged. On the left and right sides of the horizontal transfer brackets 30 in the conveying direction (the horizontal direction perpendicular to the conveying directions of the loading conveyor line and the unloading conveyor line), horizontal transfer conveyor chains 31 are respectively arranged; the sprockets at the front ends of the two horizontal transfer conveyor chains 31 are connected by a horizontal transfer drive main shaft 32, and a horizontal transfer drive sprocket 33 is arranged in the middle of the horizontal transfer drive main shaft 32. The horizontal transfer drive sprocket 33 is connected to the sprocket at the output end of the horizontal transfer drive motor 35 through a horizontal transfer drive chain 34. Thus, after the workpieces in the material box at the discharge end of the loading conveyor line are used up by the production personnel, the horizontal transfer lifting frames 28 (including the horizontal transfer brackets 30 and the material box conveying support 8 and the empty material box thereon) of the loading line horizontal transfer mechanism 17 and the unloading line horizontal transfer mechanism 18 are lifted to the same height by each group of lifting frame jacking cylinders 29. Then, the horizontal transfer drive motor 35, the horizontal transfer drive chain 34 and the horizontal transfer drive sprocket 33 are used to drive the horizontal transfer drive main shaft 32 to rotate, and then drive the two horizontal transfer conveyor chains 31 on the loading line horizontal transfer mechanism 17 and the unloading line horizontal transfer mechanism 18 to rotate synchronously and cyclically respectively, so that the empty material box is horizontally moved from the discharge end of the loading conveyor line to the feeding end of the unloading conveyor line.

[0025] When the high-efficiency bin transfer chain conveyor track is in use, first, use a forklift to place the bin filled with workpieces above the loading port transfer bracket 21, and drive the rotation of the loading port transfer drive main shaft 23 through the loading port transfer drive motor 26 to drive the rotation of the loading port transfer conveyor chains 22 on both sides, so as to move the bin filled with workpieces onto the chain conveyor track of the loading conveyor line. Then, use the side chain drive motor 4 of the loading line and the middle chain drive motor 7 of the loading line to drive the rotation of the conveyor chains in the two side chain conveyor tracks 2 of the loading line and the middle chain conveyor track 3 of the loading line respectively, so as to transport the bin transfer bracket 8 and the bin filled with workpieces on it to the processing station at the front end of the conveying direction for production personnel to pick up and use. And the number of bins entering the transverse transfer mechanism 17 of the loading line and the transverse transfer mechanism 18 of the unloading line can be controlled by the blocking of the bracket stopper 27 (usually only one bin passes through each time).
[0026] After the workpieces in the bin located at the discharge end of the loading conveyor line (i.e., above the transverse transfer mechanism 17 of the loading line) are used up by the production personnel, use the lifting cylinder 29 of each group of lifting frames to raise the transverse transfer lifting frames 28 of the transverse transfer mechanism 17 of the loading line and the transverse transfer mechanism 18 of the unloading line to the same height higher than the chain conveyor track. Subsequently, use the transverse transfer drive motor 35 to drive the rotation of the transverse transfer drive main shaft 32 to drive the synchronous rotation of the two transverse transfer conveyor chains 31 on the transverse transfer mechanism 17 of the loading line and the transverse transfer mechanism 18 of the unloading line respectively, so as to horizontally move the empty bin from the discharge end of the loading conveyor line to the feeding end of the unloading conveyor line. After that, use the unloading line chain drive motor 12 to drive the rotation of the conveyor chains in the two side chain conveyor tracks 10 of the unloading line and the middle chain conveyor track 11 of the unloading line, so as to transport the bin transfer bracket 8 and the empty bin after horizontal displacement back to the discharge port position of the unloading conveyor line, and use a forklift to remove and move the bin transfer bracket 8 and the empty bin.
