Express packages are transported along the conveyor, and packages from different destinations are transported to different grids and dropped into the corresponding sorting bags. When the number/weight of packages in this large bag reaches the specified range, the grid light will light up, reminding the staff to build and sew the package timely and to replace the large bags above in a timely manner. During this process, the information about building the package needs to be scanned by a spear to be transmitted to the sorting system.

Then how to detect the drop bags and judge the full state of the sorting bags? In the following cases we will introduce two G-TEK Sensor solution for your more reference.

Bag rack type sorting is a common method of cross belt sorting. Installing PF21T or PF21B background suppression diffuse reflection sensors at the sorting port can perform real-time detection of bagged packages. Slim type LSEC grating products can also be used to achieve precise detection of small items, express letters, audio-visual products, and other flat objects, effectively avoiding missed inspections.

Install diffuse type PM21B-900A at the side of the conveyor line of the cross sorting system and set the detection range according to the requirements. If goods are detected within the detection range, the photoelectric output responds, indicating that the goods have reached the position where they are about to be filled.
