As shown in fig. 1, 2, 3, 4, 5, 6 and 7, the present invention is installed between two electric conveyor line devices for upper and lower processes. The utility model discloses in the actual production, the work flow as follows. The PLC controls two goods on the electric conveyor line equipment on the right side and special pallets on the upper portion and the lower portion to move towards the left side and enter a turn-over space between the two supporting plates 5 through an opening 51 of the supporting plate 5 at the right end (one set of electric roller conveying assembly 1 at the lower end of the PLC controls the supporting plate to work electrically for a period of time, and a servo motor 101 drives a plurality of rollers 102 to move anticlockwise through a chain wheel and a chain, so that the goods and the pallets enter the turn-over space between the two supporting plates 5). When the left end goods move to the photoelectric switch that is close to 5 medial extremity of left end backup pad, left end backup pad inboard back, PLC control left side upper and lower parts blocks that the straight line electric jar of electric jar subassembly 10 gets electric work a period, its straight line slide bar drives stopper 1012 and moves downwards and upwards, and then plays the effect of blockking to the upper and lower end of left end goods to do benefit to subsequent turn-over. When goods on the right side move leftwards and enter the turn-over space between the two supporting plates 5, after the photoelectric switch on the inner side of the supporting plate on the right end detects the goods, the PLC firstly controls the servo motor of the electric roller conveying assembly positioned below to stop running, so that the roller 102 does not move any more (meanwhile, the PLC controls the electric conveying line equipment on the right end to stop moving and temporarily does not convey the goods any more). The PLC controls the motor reducing mechanisms 41 of the two sets of clamping electric components at the right end to work in an electrified way for a period of time, and the power output shafts of the motor reducing mechanisms rotate anticlockwise, so that the movable blocks 42 are vertically positioned at the upper end and the lower end of the right side of the right-end goods, the left and right fixing and limiting effects are achieved on the goods, and preparation is made for subsequent turning. Then, the PLC controls the synchronous motor reducer 141 of the driving mechanism to work electrically for a period of time, the synchronous motor reducer drives the screw rods 132 of the two sets of lifting mechanisms clockwise through the driving pulley 145, the transmission belt 143, and the synchronous pulley 142, and the external threads of the screw rods 132 act on the internal thread screw seats 137 of the upper and lower fixing slots, so that the upper fixing slot 103 moves downward, the lower fixing slot 103 moves upward, the two slots are close to each other at intervals, the rollers 102 of the two sets of electric conveying roller assemblies at the upper and lower ends respectively clamp the trays at the upper and lower ends of the two goods, and then the PLC controls the synchronous motor gear reducer 142 to lose power to ensure the clamping state (the guide rod 131 plays a guiding role to ensure that the fixing slot 103 can move up and down through the linear bearing 136). PLC control servo motor reduction gears 12 gets electric work, and control servo motor reduction gears 12 drives drive chain 11 through drive sprocket 22, two servo sprocket 23 and moves forward or backward a period, and then drives two backup pads 5 forward or backward 180 degrees or reversal 180 degrees (four sets of loose pulley assembly's pulley 31 is two sets of backup pads 5 rotation direction), and corotation is still the reversal and depends on the utility model discloses the current position is 0 degree still 180 degrees. Through the above, two cargos between the inner sides of the two sets of supporting plates can be controlled to realize the turnover from the lower end to the upper end. After the goods are turned over by 180 degrees, the PLC controls the servo motor reducing mechanism 12 to lose power, then the synchronous motor gear reducer 141 of the driving mechanism is controlled to work for a period of time by power, the synchronous motor reducer drives the screw rod 132 of the two sets of lifting mechanisms anticlockwise through the driving belt wheel 145, the driving belt 142 and the synchronous belt wheel 142 to rotate anticlockwise, the external thread of the screw rod 132 acts on the internal thread screw seat 137 of the upper fixing groove 103 and the lower fixing groove 103, then the upper fixing groove 103 moves upwards, the lower fixing groove 103 moves downwards, the distance between the two sets of goods is pulled, the rollers 102 of the two sets of electric conveying roller assemblies at the upper end and the lower end do not clamp the trays at the upper end and the lower end of the two goods (after the two sets of electric conveying roller assemblies are in place, the PLC controls the synchronous motor reducer 141 to lose power), and the follow-up two goods can be output to the left electric conveying line. The PLC controls the motor reducing mechanisms 41 of the two sets of clamping electric components at the right end to work electrically and the power output shafts thereof to rotate clockwise for a period of time, so that the movable block 42 is horizontally positioned at the right end and between the upper ends and the lower ends of the two lower right rollers 102, and subsequent goods can enter the turn-over space between the two supporting plates 5. Two sets of sharp electric jar that the upper and lower part in PLC control left side blockked electric jar subassembly 10 get electric work a period, and its sharp slide bar drives stopper 1012 and upwards reaches the downstream, no longer plays the effect of blockking to the upper and lower end of left end goods to do benefit to behind the turn-over goods output to the electronic transfer chain equipment of left end. Then PLC control backup pad originally one set of (being located the lower extreme at this moment) electric drum conveyor components in upper end gets electric work a period, and its servo motor 101 drives a plurality of cylinders 102 anticlockwise motion through sprocket, chain, makes the goods and tray get into on the electronic transfer chain equipment of left end after the turn-over, then carries next station through the electronic transfer chain equipment of left end. The control process is completely consistent with the control process, the PLC can control two cargos of the next batch to enter the turnover space between the two supporting plates 5 for turnover work, and the turnover work can be continuously carried out on the cargos in a repeated mode (after the cargos are turned over last time, the rotating direction of the turnover supporting plates of the next batch is just opposite to the turnover direction of the cargos turned over last time). Through the aforesaid, the utility model discloses two sets of electronic transfer chain equipment use in coordination, do not need artificial operation, can realize the turn-over through the product of tray transportation or part automatically, realized from this that the equipment is whole compacter to reduced the production side labour cost expenditure, and improved work efficiency.
