Background
At present, more and more automatic sorting equipment and solutions, such as cross belts, sorting platform AGVs, seeding walls and the like, are applied to all links in the field of logistics sorting. The sub-sowing wall has the characteristics of low cost, high timeliness, flexible deployment, small occupied space and the like, and also appears in an automatic replacement stage of warehouse rechecking and sorting. The conventional distributing wall equipment consists of a packet supply platform, a main frame, a distributing vehicle and a grid shelf system, wherein in order to further improve the automation and the intelligent degree and reduce the labor intensity, the grid shelf system usually adopts IO (Input/Output), RFID (Radio Frequency Identification) and other electrical equipment to display the states of full boxes (order completion), empty boxes (order starting), abnormality and the like of a plurality of or single grid container, so that the manual subsequent box changing and other operations are convenient.
Currently, the cargo box detection technology of the existing grid shelf generally designs the IO detection, lighting module and RFID card reading function independently. The system comprises an IO detection module, a lighting module, an RFID reading card and a bus, wherein the IO detection module consists of a single IO-to-bus module and a plurality of groups of sensors and is used for detecting the full box and empty box states of all the grids and transmitting the full box and empty box states back to an upper system through a bus, the lighting module is arranged on each grid for receiving bus information and lighting lamps with different colors for indicating different states of the grids, and the RFID reading card is used for arranging an RFID module on each grid for detecting and receiving RFID label information on a grid container and reporting the RFID label information through the bus.
However, the following technical problems generally exist in the above manner:
Firstly, buses and modules are more, so that wiring difficulty and potential fault points are increased;
Secondly, when the container is put on the shelf, the container is easy to put askew, and the container cannot be aligned with the card reading device.
The above information disclosed in this background section is only for enhancement of understanding of the background of the inventive concept and, therefore, may contain information that does not form the prior art that is already known to those of ordinary skill in the art in this country.

The above-mentioned related matters are taken as an invention point of the present disclosure, and solve the technical problem that the second container mentioned in the background art cannot be aligned with the card reading device.

If the above factors are solved, the effect of aligning the container with the card reader can be achieved. To achieve this, the locator includes a locating feature that is aligned with a locating feature on the container to prevent the container from being skewed when it is loaded. In addition, the container can be fixed by adsorbing the container through an adsorption member included in the positioner and an adsorption mechanism on the container.
