When preparing the lithium ion high nickel anode material, the raw materials are loaded by adopting a sagger, and then are put into a sintering furnace to be calcined at high temperature under the condition of introducing oxygen, and the sintering process is the most important process at the core.
At present, the sagger is transported by a conveyor. Here, taking a process of sintering a group of four sagger as an example, four saggers are set as sagger a, sagger B, sagger C and sagger D, the four saggers are input into the conveyor from the feeding end of the conveyor in the sequence of sagger a, sagger B, sagger C and sagger D, and the sagger D is positioned at the front side of the transportation direction of the sagger a. After being conveyed by the conveyor, the four saggers are required to be arranged into two rows and two columns so as to meet the sintering process requirements of customers. When existing conveyors output, four magazines are typically AB in a column, CD in a column, and CD is output prior to AB, i.e., ordered in AB-CD; however, there are customer process requirements that require that AB columns be output first and CD columns be output later, i.e., in CD-AB order, and that the output order of AB columns and CD columns be inverted. No conveyor exists in the market to invert the output sequence of the sagger, and the process requirements of customers cannot be met.
