Problems solved by technology

[0003] The currently commonly used feeder tables are generally two-stage or four-stage, which either have requirements for the placement of packages or mail, or are not efficient enough to meet the needs of large-scale automatic transmission
Generally speaking, increasing the number of belt segments and reducing the length of each segment will make the mail control method more flexible, which in turn will improve efficiency, but it will also put forward higher requirements for the control method

Embodiment Construction

[0033] The control system of the present invention regards the triangular section (upper section) close to the main ring as the first section, and sorts in turn, and the miter section close to the belt conveyor as the ninth section. A measuring photoelectric gantry is set between the sixth section and the seventh section for measuring the size of the mail, and the seventh section is a weighing section. The nine-segment motors are all controlled by frequency converters and connected to the control system through the Profibus-DP bus system. The control system uses a programmable logic controller as the main control CPU, and connects and communicates through the DP module (and the frequency converter), the serial port module (and the upper-package track board), the digital IO module and related peripheral equipment and devices, and through the Profinet interface Communicate with the belt conveyor, the main ring PLC, and the terminal of the supply table. The technical scheme of t...

Abstract

An automatic piece supplying table for a cross-belt sorting machine adopts a nine-section type structure. A piece feeding section closest to a main ring is arranged to be the first section. Sections are successively sequenced. The chamfered joint section close to a belt conveyor is arranged to be the ninth section. A measurement photoelectric portal frame is arranged between the sixth section and the seventh section and used for measuring the size of a parcel. The seventh section serves as the weighing section. Drive motors of all the nine sections are connected with a control system through a bus. The control system comprises a master controller which is connected with a frequency converter, a parcel feeding rail plate, a digital IO module, the belt conveyor, a main ring PLC and a piece supplying table terminal.

Description

technical field [0001] The invention belongs to the technical field of logistics equipment, and in particular relates to an automatic feeding platform control method for a cross-belt sorter. Background technique [0002] The feeding table is one of the core equipment of the cross-belt sorter. The feeding table is used to automatically import mail and parcels of a certain size and quality into the main ring, and at the same time send the mail information to the main ring PLC. Traditionally, the feeding table needs to be placed manually at the end of the loading section. With the increase of labor costs, the postal and logistics industries have higher and higher requirements for the automation of equipment. It is necessary to develop an automatic feeding table that can meet the need to save manual decorations and directly transfer directly from the unloading port through the belt conveyor. . Since the loading position is far away from the feeding table and unattended, this ...
