Description

Technical Field

[0001] The utility model belongs to the technical field of express sorting, and relates to a vacuum adsorption mechanism for high-speed and high-precision sorting of express items. Background Art

[0002] The cross-belt sorting machine includes the transportation, identification and classification of express parcels. The express parcels enter the system through the conveyor belt and are then transported by the conveyor belt on the trolley or cart of the cross-belt sorting machine. During the transportation process, the express parcels pass through the visual sensor or scanning system to identify the barcode or radio frequency identification tag on the express parcel, thereby obtaining the express parcel information; the electronic control system instructs the conveyor belt to run the express parcel to the designated cross-belt according to the identified information, picks the express parcel from the conveyor belt and runs it to the corresponding sorting port to complete the classification and sorting.

[0003] At present, the linear speed of express parcels during turning transportation must be less than 2.5m / s, because once this speed is exceeded, the express parcels will be thrown out due to excessive centrifugal force, and the conveyor belt needs to slow down in advance when running the express parcels to the designated cross belt, otherwise it will easily lead to untimely sorting, sorting errors, and reduced sorting efficiency. Utility Model Content

[0004] In response to the above-mentioned problems existing in the prior art, the present application provides a vacuum adsorption mechanism for high-speed and high-precision sorting of express parcels.

[0007] An electric roller and a driven roller are installed between the anti-swing trolley wall panel 1 and the anti-swing trolley wall panel 2. An air trough belt is transmitted between the electric roller and the driven roller. The electric roller can rotate clockwise or counterclockwise. When the electric roller rotates clockwise, the express mail is sorted to the right compartment, and when the electric roller rotates counterclockwise, the express mail is sorted to the left compartment.

There are multiple waist-shaped holes connected below the suction holes. The waist-shaped holes are provided on the air trough panel. The extension direction of the waist-shaped holes is consistent with the length direction of the air trough panel. An air trough is provided below the air trough panel. The air trough is connected to the fan through an air duct. When the fan is running, air is drawn to generate negative pressure between the air trough and the air trough panel. The generated negative pressure absorbs the express to the air trough belt through the suction holes, so that the express maintains its posture when running at high speed.

[0009] When the express is about to reach the sorting grid, the fan generates high negative pressure, and the electric roller and the driven roller drive the air trough belt to drop the express accurately to the unloading grid.

[0010] As a preferred implementation mode of the utility model: an air duct interface is provided between the air duct and the air trough, the high negative pressure generated by the air trough belt absorbs the express items, and the air duct interface is fixedly installed on a wall panel of the anti-swing trolley.

[0014] As a preferred implementation mode of the utility model: the fan adopts one or more of an axial flow duct fan, a DC brushless centrifugal fan, and a DC brushless vortex fan, and the operating voltage of the fan is 24V to 48V.

[0015] The beneficial effects of the utility model are:

[0016] The utility model discloses a vacuum adsorption mechanism for high-speed and high-precision sorting of express parcels. The parcel supply platform transports the parcels to an anti-swinging trolley on a circular track. The arranged wind trough is connected to the fan through an air duct. The fan continuously draws air when it is running, so that negative pressure is generated between the wind trough and the wind trough panel. The generated negative pressure firmly adsorbs the parcels to the wind trough belt through small round holes, so that the parcels can still maintain a stable posture when turning at high speed, thereby improving the conveying speed. When the parcel is about to arrive at the designated position, the wind trough belt quickly rotates to transport the parcel under the high negative pressure state generated by the fan, and the electric roller arranged on the anti-swinging trolley can accurately transport and sort the parcels to the unloading grid, which is convenient and efficient.
