The information acquisition unit 40 may obtain the classification information by directly measuring the object being transported, or may be input from the outside through a communication means. In this case, the classification information is recognized from the outside before the article carrying apparatus 1 loads the article.

The classification information may be identifier information, classification code, or address information of an item represented by a barcode, RFID, or letter. For example, if the article is a mail item, a barcode is printed or attached to the mail item, and the mail identifier information ID is recorded on the barcode. The mail identifier information is a code including a series of numbers such as an invoice number and a reception number uniquely assigned to a mail for mail management when the mail is received. The postal matter identifier information of the barcode is stored in the database 5 and used as an identifier for tracking or referring to the postal matter.

In the case of a laser scanner, the moving information is scanned to recognize the classification information. In the case of the RF reader, RFID information attached to the article is read to recognize the identification information.

Various information is stored in the database 5. The article classification information and the article classification location information may be mapped and stored in the database 5. For example, information on which transportation path is to be transported is stored according to a bar code or address information of a mail.

The information obtained by the information acquisition unit 40 may be position and attitude information of the article. For example, an image of the articles can be obtained and the direction of movement of the article can be determined therefrom. To this end, the information acquisition unit 40 may be a camera, and the number thereof is not particularly limited. The information acquisition unit 40 obtains an image signal for each of the items to be transferred, converts the image signal into an electrical signal, and transmits the image signal to the information processing unit 42. The information acquisition unit 40 may be supported by the support and installed on the upper end of the transport path, but the shape is not limited thereto.

The information processor 42 analyzes the image acquired by the information acquirer 40 to recognize the position and posture of the articles. The information processor 42 may determine the location of the goods in real time and track the movement position and posture of the goods for the goods to be transported in bulk using image processing and recognition technology. To this end, the information processor 42 may detect an object from the image data and detect the position and posture of the article from the detected object. Object recognition technology using image can improve the efficiency of automation by applying image recognition technology even though it operates in some limited environment. Image processing is not easy because of the large amount of computation. Real-time processing based on measured results can be used with GPUs in parallel to perform real-time control. As the information processor 42 sequentially assigns numbers to each recognized article, the controller 3 may sequentially select each article when the controller 3 individually controls each article.

The position detecting unit 44 detects a transfer point of the article in the conveying path, and may be a position detecting sensor. When the transfer point at which the article is located is detected by the position detecting unit 44, the information obtaining unit 40 may acquire more accurate position information from the image of the corresponding point article.

The control part 3 receives the information for direction determination from the information provision part 4, and transmits a control command to the conveyance unit 2. For this purpose, the control unit 3 individually or group-controls the direction changer in the conveying unit 2 according to the information received through the information providing unit 4 while conveying the articles without stopping through the conveying unit 2. To process the items. The detailed structure of the control part 3 is mentioned later with reference to FIG.

The article control unit 30 according to an embodiment determines a moving direction of each article using the article classification information received from the information providing unit 4. The direction of travel may be determined depending on the purpose of the treatment. For example, for the purpose of classification, the direction of progress of each article can be determined according to the classification conditions set in advance. For example, the goods control unit 30 switches the moving direction to the left when the first item being transported along the transport path to the Seoul, and the right direction to the right when the second item is the mail to the Daejeon. Switch to The article control unit 30 may change the posture as well as change the position of the article when each article is transferred. For example, the posture may be changed such that the narrow side of the object faces the front side of the transport path and the long side faces the side of the transport path.

The direction change control unit 32 controls the direction change of each direction changer by individual control or a group so that each article proceeds in accordance with the advancing direction determined by the article control unit 30. The feed rate control unit 34 controls the feed rate of each article. Accordingly, not only the direction of movement of the moving article can be changed, but also the speed can be adjusted, thereby achieving the best performance regardless of the arrangement of the supplied article.
