A sorting method of a modularized cam sorting device comprises the following steps:

s0: and the scanning camera uploads the scanned bar code information of the parcels to the upper computer control system, and the upper computer control system calculates that the parcels should be sorted and unloaded at the module n.

S1: the parcel moves forward under horizontal power transmission mechanism's transportation, when arriving module 1, triggers module 1's photoelectric sensor, and the sensor sends signal for upper computer control system.

S2: the parcel continues to move forward to big module 2, triggers module 2's photoelectric sensor, and the sensor sends signal transmission for upper computer control system.

S3: the parcel continues to move forward to big module 2, triggers module 2's photoelectric sensor, and the sensor sends signal transmission for upper computer control system.

Sn: when the parcel reachd module n, trigger the photoelectric sensor of module n, the sensor gives upper computer control system with signal transmission, and upper computer control system judges that the parcel should carry out the letter sorting here and unload, sends the order and gives module n, and module n's cam letter sorting motor is rotatory, pulls out horizontal power transmission mechanism with the goods, accomplishes and unloads.

Detailed Description

The technical scheme of the invention is further specifically described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a modular cam sorter is provided, including a horizontal power transmission mechanism of fig. 1 and the cam sorter of fig. 2.

The horizontal power transmission mechanism comprises a roller 1, a V-belt 2 and a horizontal transport motor 3; the horizontal transport motor 3 drives the roller 1 to rotate through the V-ribbed belt 2, and transports the goods 12 to a specified destination.

The vertical cam sorting mechanism is the core content of the invention, and comprises a plurality of groups of cams 6, a cam shaft 13, a synchronizing wheel or a chain wheel 5, a belt 9, a cam sorting motor 4, an origin sensor 11, a horizontal photoelectric sensor 8, a vertical photoelectric sensor 7 and a central processing unit 14;
