The width of the placing conveyor 21 is wide, which is the most upstream conveyor on which the work is placed by a manual work or a robot arm or the like, and the wide width can be easily placed in consideration of the work precision and the placing convenience, and moreover, a plurality of work pieces can be placed in each row (see fig. 7), so that more work pieces can be stored, and the work pieces enter the single row conveyor 22 along with the continuous movement of the placing conveyor 21. The single row conveyor 22 is relatively narrow in width and only one workpiece can be placed in each row (see fig. 7), so that the workpieces are organized into a single row on the single row conveyor 22.

The working principle is as follows:

the sorting method of the cylinder sorting device comprises the following steps:

s1, moving a workpiece to a feeding station 11;

s5, conveying the workpiece to the upper part of the detection station 12 by the feeding manipulator, and rotating the feeding vertical mechanical arm 42 during or after conveying the workpiece to the upper part of the detection station 12, wherein the feeding clamping disc 44, the two clamping jaws 441 and the workpiece synchronously rotate until the radial direction of the sliding vane groove 93 of the workpiece is consistent with the radial direction of the guide plate 82, and the feeding vertical mechanical arm 42 stops rotating;

s6, the free end of the feeding vertical mechanical arm 42 runs downwards until the inner hole 94 of the cylinder moves to the guide cap 83;

s7, the two clamping claws 441 of the feeding clamping disc 44 are loosened, and the workpiece falls down by gravity until the positioning operation is completed (namely, the lower surface of the air cylinder 90 contacts the upper surface of the detection table 80);

s8, detecting by using a detector, checking the inner diameter data d1 of the detected workpiece with a 'step interval table', and determining that the workpiece is of a certain specific model; how to detect the inner diameter of the steel pipe is the prior art and is not repeated;
