Unloading control method for crossed belt sorting machine

Abstract

The invention discloses an unloading control method for a crossed belt sorting machine. A trolley with phototubes, a conveying main line, a control system, a supplied parcel conveying belt provided with gratings and phototubes and a parcel receiving area are included. The supplied parcel conveying belt is used for throwing parcels and transporting the parcels to the trolley. The trolley is used for receiving the parcels and transporting the parcels to the parcel receiving area. The conveying main line is used for driving the trolley to run. The gratings are used for detecting the center positions of the parcels and collecting size and weight information of the parcels. The phototubes are used for detecting the positions of the parcels. The control system is used for collecting and processing detection information of the gratings and the phototubes, adjusting the speed of the supplied parcel conveying belt, setting the parcel sorting position, setting the starting time point and the starting speed of the trolley during unloading and driving the trolley to act. The parcel receiving area is used for receiving the parcels unloaded from the trolley. By means of the unloading control method for the crossed belt sorting machine, mutual collisions and extrusion between the parcels which have the great disparity in weight and size during unloading are reduced, the damage rate of the parcels is reduced, and the sorting quality is improved.

Description

technical field [0001] The invention relates to the technical field of logistics automatic sorting, in particular to a method for controlling unloading of a cross-belt sorter. Background technique [0002] The cross-belt sorting system is connected by the main drive belt conveyor and the trolley (referred to as "cart") carrying the small belt conveyor. When the trolley moves to the specified sorting position, it turns the belt to complete the sorting process. The task of sorting and sending out parcels. Because the main drive belt conveyor and the belt conveyor on the trolley are in a cross shape, it is called a cross belt sorter. In the prior art, when sorting and unloading, the delivery conveyor belt is usually used to transport the parcels to be sorted to the trolley of the main drive belt conveyor (hereinafter referred to as "conveyor main line"). When the parcels are to be unloaded to the receiving area , the control system controls the movement of the trolley through...

Problems solved by technology

In the prior art, there is no difference in unloading, that is, the parcels in the same receiving area are unloaded into the receiving area from the same position at the same speed regardless of size or weight; Influenced by the friction coefficient of materials, etc., this kind of indiscriminate unloading often causes packages of different sizes and weights to pile up together, which can easily lead to damage to some packages.
