Cross belt sorting method, sorting control system and cross belt sorting system

Abstract

The invention discloses a cross belt sorting method, a sorting control system and a cross belt sorting system. The sorting method comprises the steps that S1, a top surface image of a sorting trolleyis received, and the state of the sorting trolley is determined; S2, when determining that only one object exists on the sorting trolley, a sorting grid corresponding to bar code information on the object and position coordinates of the sorting grid on the sorting trolley are determined; S3, virtual coordinates are converted according to the position coordinates, wherein the virtual coordinates are four vertex coordinates of a minimum enclosing rectangle of projection of the object on the sorting trolley; S4, a sorting starting point is calculated according to the virtual coordinates and the target sorting grid; and S5, when the sorting trolley reaches the sorting starting point, the sorting trolley is controlled to start sorting. According to the scheme, the position of the object on thesorting trolley is considered, the sorting starting point is accurately calculated based on the minimum enclosing rectangle of the object, the sorting precision can be effectively improved, the systemerror sorting rate is reduced to be lower than one ten thousandth from one thousandth, and the sorting reliability is greatly improved.

Description

Technical field [0001] The present invention relates to the field of logistics sorting, especially cross-belt sorting methods, sorting control systems, and cross-belt sorting systems. Background technique [0002] The cross-belled sorting system is joined by the main drive belt conveyor and a trolley containing a small tape conveyor (referred to as "sorting car"), when "sorting the cart" moves to the specified sorting When the location, the belt is turned to complete the task that puts the product sorting. [0003] The main process of cross-belt sorting includes the upper package process and the next package process, where the following process is a key process that affects the accuracy of the sorting accuracy. The existing lower package method, such as the method disclosed by the announcement No. CN106865159B, but it When the package is under the package, the position of the wrapped in the sorting trolley is not considered, therefore, there is still a certain error, and the sort...

Problems solved by technology

[0003] The main process of cross-belt sorting includes the process of packing and the process of packing, wherein the process of packing is the key process that affects the accuracy of sorting. The existing packing method, such as the method disclosed by CN106865159B, but its The position of the parcel on the sorting trolley is not considered when unpacking, so there is still a certain error when sorting, and the sorting accuracy may be further improved
