Description

A kind of cargo sorting device and method

technical field

The invention relates to a sorting device, in particular to a cargo sorting device and method.

Background technique

Sorting is an important link in the logistics industry. It is mainly necessary to ensure the efficiency, economy and low error rate of sorting. The current sorting methods are mainly divided into three types:

(1) Manual sorting, that is, it is completely manual, without the assistance of any other mechanical tools. This method is inefficient and has a high error rate, and the enterprise needs to pay high labor costs, and the sorting quality is greatly affected by the emotions of the workers, and "violent sorting" is prone to occur.

(2) Semi-automatic sorting. This method is mainly to pick goods through mechanical assistance, use identification devices to obtain goods information, and use manual methods to sort out goods. This method has a low degree of automation, low efficiency, relatively high labor costs, and the work process is cumbersome, and the sorting quality cannot be guaranteed.

(3) Automatic sorting. This method uses pre-programmed programs to sort according to the set method, and uses sorting equipment to control the sorting without human intervention. However, the existing automatic sorting devices currently on the market generally use barcode technology to identify cargo information, and the accuracy of information identification is low. After the goods are sorted, the guide rails of the next pieces are not concentrated, resulting in the bulky size of the whole device, large floor space, and increased use costs. It is unfavorable for the popularization of sorting device.

Contents of the invention

Step 1: Make the goods with electronic tags pass through the identification device during the conveying process of the conveying device. The identification device reads and obtains the goods information on the electronic tags of the objects, and transmits the goods information to the computer. The objects continue to be conveyed, and the conveying speed is controlled by the encoder. detection until it falls from the conveying device;

Step 2: If the information on the electronic label of the goods cannot be read or the label cannot be recognized, the computer makes the control system control the guide plate rotation electromagnet in the object guiding device to drive the reversible guide plate to make a flip action, and the object slides along the reversible guide plate out;

If the information on the electronic label of the goods can be recognized and processed normally by the control system, the object guiding device will not act, and the objects will slide down the funnel-shaped channel and fall to the middle of the cross-shaped guide rail in the sorting device;

Step 3: The computer judges the specific location where the goods need to be sorted through the information on the electronic label of the goods, and then controls the control system and the guide rail rotation electromagnet to make a rotation action. After the rotation is in place, the control system controls the push-pull rod to raise or lower The action makes the objects slide out along the inclined guide rails, and similar objects slide out from the same guide rails to realize the sorting of objects.

In the first step, if the speed of the conveyor belt is too fast or too slow, a reference value can be set through the computer control system, and the difference between this value and the encoder detection value is input into the motor speed adjustment controller, and then drives the motor The speed of the belt is reduced or increased so that the transmission speed of the belt is as expected.

Compared with the prior art, a cargo sorting device can transport objects through a conveying device. During the conveying process, the identification device reads the cargo information in the electronic tag on the object. After the cargo leaves the conveying device, it falls into the object guiding device, and the label is damaged. Or unidentifiable goods are led out by the object guide device, and the goods whose labels can be identified fall out of the object guide device and fall into the sorting device for sorting. The area is small, saving the practical cost of land.

Further, a cargo sorting device can make the cross-shaped guide rail complete the inclination and rotation in the direction of the four guide rails through the push-pull rod and the guide rail rotation electromagnet.

Further, the radio frequency identification technology (RFID) adopted by a cargo sorting device has the advantages of high reliability, fast recognition speed, and reusability, which effectively improves the sorting efficiency and accuracy of the entire sorting system and saves sorting costs. The required hardware cost.

The sorting method of a cargo sorting device has a simple control process, can realize rapid processing of cargo information, and has fewer processing links for control information, so that the response speed of the entire system is fast, and the sorting process can basically be realized without human intervention. It greatly reduces the labor intensity of sorting personnel and saves labor costs.
