Wherein each grouping base unit 50 is further provided with a floating power device 60, and the floating power device 60 comprises:

The working principle and the beneficial effects of the technical scheme are as follows: the conventional sorting wheel set is directly and fixedly mounted on the main conveying frame, and the sorting wheel set needs to be slightly higher than the height of the conveying frame to apply a lateral component force to the workpiece to be sorted, the lateral component force is actually generated by static friction force generated between the sorting wheel and the workpiece, that is, the lateral component force applied by the sorting wheel is static friction force, and the lateral component force is larger when the workpiece is heavier, so that the static mounting mode can meet most workpiece sorting requirements in practical use. However, when the weight of the workpiece to be sorted is larger than the maximum weight capable of being sorted by the sorting wheel, the workpiece cannot enter the sorting conveying frame in time under the action of lateral component force of the sorting wheel, and sorting cannot be performed normally. In order to avoid the phenomenon, the technical scheme adopts a floating installation mode to fix the sorting wheel on the main conveying frame, so that the sorting wheel can sort the workpieces with different weights in two working forms of light workpiece fixed sorting and heavy workpiece floating sorting.
The sorting wheels are grouped in such a way that the sorting wheels on the same reference straight line are grouped into one group, the reference straight line being in line with the direction of travel of the workpieces (the sorting wheels are grouped into 5 groups as shown by the dotted lines in fig. 2). Each grouping base unit 50 includes a square frame 51, a drive sheave 58, and a floating power device 60. The square frame 51 passes through the U-shaped bottom plate 41 of the fixed vertical plate 52 on both sides, the square frame 51 can slide up and down on the fixed vertical plate 52, and the first driving shaft 59 drives the sorting wheel 30 to rotate by using the transmission concave wheel 58.
Under the action of the floating power device 60, the sorting wheel 30 has two working states: the fixed sorting state of the light workpieces and the floating sorting state of the heavy workpieces. Wherein, the fixed sorting state of the light workpieces sorts the workpieces with lighter weight, and the floating sorting state of the heavy workpieces sorts the workpieces with heavy weight. The floating power device 60 is switched between the interlocking state and the separated state with the grouping base unit 50 by the interlocking fluted disc 65. As shown in fig. 8, when the interlocking toothed disc 65 is at the rightmost end in the drawing, the floating power device 60 is in an interlocking state with the grouping base unit 50, and the sorting wheel 30 is in a heavy workpiece floating sorting state; when the linked toothed disc 65 is at the leftmost end in the drawing, the floating power device 60 is separated from the grouping base unit 50, and the sorting wheel 30 is in the light workpiece fixed sorting state.
Fixed sorting state of light workpieces: in this operation state, the floating power device 60 is separated from the grouping unit 50, the sorting wheel 30 is fixed on the main output frame 10 by the square frame 51, and the driving roller shaft 511 provides power for the first driving rotating shaft 59 to rotate the sorting wheel 30. When the workpieces are conveyed to the sorting wheel 30 by the driving of the conveying roller 12, under the action of the gravity of the workpieces, the square frame 51 sinks along the strip-shaped chute 54, and the sorting wheel 30 is always higher than the main output frame 10 under the buffering of the buffer spring 55, and the driving roller shaft 511 in each group of grouping basic units 50 is driven by the third synchronous belt 514 to synchronously rotate so as to synchronously rotate the sorting wheel 30.
Heavy workpiece floating type sorting state: in this operating state, the floating power device 60 is in linkage with the grouping unit 50, and the floating power device 60 drives the square frame 51 and the sorting wheel 30 to float up and down. The specific working process of the floating power device 60 is as follows: the arc-shaped disc 67 is driven by the fourth synchronous belt 69 to rotate downwards, the linkage fluted disc 65 drives the driven fluted disc 64 and the driving fluted disc 610 to regularly and continuously switch between separation and linkage in the rotating process of the arc-shaped disc 67, and when the driven fluted disc 64 and the driving fluted disc 610 are linked, the square frame 51 drives the sorting wheel 30 to float up and down under the driving of the offset turntable 62, namely, the sorting wheel 30 is regularly switched between the highest position and the lowest position. In addition, as shown in fig. 5, the length of the floating link 61 is gradually decreased, when the heavy workpiece reaches the sorting wheel 30, the sorting wheel 30 is at the lowest position to smoothly lift the workpiece, and reaches the highest position under the driving of the offset turntable 62, when the heavy workpiece is at the highest position, the workpiece is inclined towards the sorting conveying frame 20, the workpiece has a gravity component towards the sorting conveying frame 20, and the heavy workpiece moves onto the sorting conveying frame 20 under the double actions of the gravity component and the lateral static friction force of the sorting wheel 30 to realize sorting. In addition, since the lengths of the floating links 61 in the plurality of grouping units 50 are gradually reduced and the rotation angle of the offset rotary table 62 in each grouping unit 50 is 15 degrees behind that of the previous offset rotary table 62, the overall movement track of the plurality of sorting wheels 30 is spirally waved, so that heavy workpieces can be sorted more smoothly.
