In operation, the crankshaft 32 to be polished is optionally dumped into the hopper 1, and the PLC controls the pushing cylinder 24 to push the pushing plate 23 to intermittently and reciprocally slide. When the pushing cylinder 24 is completely retracted, the pushing plate 23 moves downwards as a whole, the upper end surface of the lower section of the pushing plate 23 moves to the bottom of the hopper 1, the upper end surface of the middle section of the pushing plate 23 moves to be flush with the upper end surface of the inner wall of the innermost layer of the hopper 1, and the upper end surface of the upper section of the pushing plate 23 moves to be flush with the upper end surface of the inner wall of the middle layer of the hopper 1; when the pushing cylinder 24 is fully extended, the pushing plate 23 is wholly moved upwards, the upper end face of the lower section of the pushing plate 23 is moved to be flush with the upper end face of the inner inclined wall of the innermost layer of the hopper 1, the upper end face of the middle section of the pushing plate 23 is moved to be flush with the upper end face of the inner inclined wall of the middle layer of the hopper 1, and the upper end face of the upper section of the pushing plate 23 is moved to be flush with the upper end face of the inner inclined wall of the outermost layer of the hopper 1, namely the open edge of the hopper 1.

When the crankshafts 32 pass through the inclined slide ways 5 of the arrangement buffer mechanism, the crankshafts 32 can only longitudinally enter the inclined slide ways 5 due to the restriction of passing width, and the journals 33 cannot be supported due to the fact that gaps exist on the inclined slide ways 5, under the action of the dead weight of the crankshafts 32, the journals 33 automatically droop into the gaps of the two electric rollers 10, and therefore posture adjustment of each crankshaft 32 on the inclined slide ways 5 can be automatically completed, the crank parts 34 face upwards, and the journals 33 face downwards.

When the crankshaft 32 is transferred from the single-row buffer channel 6 to the transfer mechanism, under the control of the PLC, the overturning driving cylinder 16 drives the rack 35 to slide to drive the gear 36 to rotate, so that the rotating shaft 15 drives the overturning arm 12 to overturn to the tail end of the single-row buffer channel 6, the crankshaft 32 conveyed from the single-row buffer channel 6 is received through the crankshaft clamping jaw, then the overturning arm 12 is overturned and reset, the PLC controls the lifting table 11 to lift the overturning arm 12 and the crankshaft 32, and the height drop of the inclined slideway 5 and the single-row buffer channel 6 caused by inclined arrangement is compensated, so that the height of the feeding table is matched with the height of the feeding table 2. Then the PLC controls the transfer gripper 19 to clamp the crankshaft 32 conveyed by the lifting table 11, and then the crankshaft 32 is driven to move forwards by the suspension driving cylinder 30 under the control of the PLC, the transfer gripper lifting cylinder 27 is driven to move downwards, and the transfer gripper 19 releases and other multi-step operations transfer the crankshaft 32 to the last crankshaft placing groove 25 of the fixed material rack 17 on the material loading table 2, so that the transfer and the handover of the crankshaft 32 from the arrangement buffer mechanism to the material loading table 2 are completed. The shuttle material frame 18 can be lifted and moved back and forth under the drive of the shuttle material frame driving cylinder 21 and the shuttle material frame lifting cylinder 26 controlled by the PLC, after the shuttle material frame 18 is lifted, the crankshaft 32 in one crankshaft placing groove 25 of the fixed material frame 17 can be lifted and moved forward by one step and then lowered, so that the crankshaft 32 is placed in the previous crankshaft placing groove 25 on the fixed material frame 17, and the stepping forward movement of the crankshaft 32 on the fixed material frame 17 is completed in a circulating mode, the conveying beats of the crankshaft 32 are further optimized while the conveying paths of the crankshaft are prolonged, and the production beats of the crankshaft polishing line are matched with the production beats of the crankshaft polishing line better. Under the control of the PLC, the output gripper 20 grips the crankshaft 32 in the forefront crankshaft receiving groove 25 of the fixed frame 17 also by the drive of the suspension drive cylinder 30 and the transfer gripper lifting cylinder 27, and then moves to the output position, and performs the transfer of the crankshaft 32 with the receiving device on the crankshaft polishing line.
