Problems solved by technology

Due to its relatively simple calculation method, irregular objects may protrude from the outer edge of the trolley when they are transported to the trolley belt conveyor. Such objects are easily disturbed when running at high speed, and an alarm occurs or the feeding is inaccurate, resulting in a wrong package rate. higher

Embodiment Construction

[0013] Further illustrate below in conjunction with the embodiment of accompanying drawing

[0014] Such as figure 1 As shown, the bag-up platform includes a belt conveyor 1 in the bag-up section, a belt conveyor 2 in the synchronous section, and a belt conveyor 3 in the confluence section. The measurement light curtain 5 is installed between the belt conveyor 1 of the upper bag section and the belt conveyor 2 of the synchronous section, the light curtain controller and the programmable control PLC are installed in the control box 4, and the measurement light curtain and the light curtain controller are connected by cables. The programmable control PLC and the light curtain controller are connected through RS485 wiring, and the free port communication protocol is used for communication. It is required to measure the distance between the first optical axis of the light curtain and the edge of the belt to be an optical axis. It is required that when the object passes through t...

Abstract

The invention provides a method for measuring irregular objects on the bag loading platform of cross-belt sorter. The bag loading platform comprises a measuring light curtain, a light curtain controller, and a programmable logic controller (PLC). The measuring light curtain and the light curtain controller are connected through a power cable. The programmable logic controller is connected with the light curtain controller through an RS485 junction manner and communicates under a free port communication protocol. According to the invention, in order to make irregular objects drop completely in the outer edge of a cart, and to reduce the requirements on the positions of the objects by manual placement through the bag loading platform and on the package appearance of the objects onto the bag loading platform, a mathematical modeling process is carried out for the object testing manner with the introduction of analytic geometric operations to develop a mature measuring method for the sizes and positions of irregular objects, which improves the accuracy of loading bags and reduces the wrong packet rate while improving the suitability of the bag loading platform and reducing the labor intensity of the operation men.

Description

technical field [0001] The invention belongs to the technical field of logistics, and in particular relates to a method for measuring irregular objects on a package table of a cross-belt sorter. Background technique [0002] In the postal and logistics industries, cross-belt sorters are often used, and with the improvement of the sorting capacity of cross-belt sorters, the matching of automatic bag feeding equipment is gradually becoming popular. With the continuous improvement of customer requirements, the detection device of the packing table is also constantly updated. The most basic device is to use the measuring light curtain or the measuring photoelectric group to measure the position and approximate size of the object on the packing table. Due to its relatively simple calculation method, irregular objects may protrude from the outer edge of the trolley when they are transported to the trolley belt conveyor. Such objects are easily disturbed when running at high speed,...
