Description
Technical Field
The invention relates to the technical field of logistics, in particular to a method for logistics by adopting a travelling crane.
Background
In the feeding procedure of a smelting factory in the casting industry, a travelling crane and electromagnetic chuck mode is usually adopted to suck out magnetic raw materials from a material pit as required and transfer the magnetic raw materials to a smelting furnace mouth or a furnace platform transfer trolley corresponding to the smelting furnace mouth. To simplify the operation, a melting furnace throat usually corresponds to a hearth transfer trolley.
In a workshop with compact production rhythm, a plurality of main charging traveling cranes are often used and provided with a standby charging traveling crane for ensuring the continuity of production. When any one main feeding travelling crane is abnormal or fails, the standby feeding travelling crane can be immediately put into use instead, and other feeding travelling crane workshops can also be mutually replaced for use.
Because the parameters of the electromagnetic chuck hung under each charging travelling crane cannot be completely consistent, and the block sizes in the material pits are different, the operating parameters (furnace area, furnace number and pit number in the charging jurisdiction, the corresponding batching parameters of the electromagnetic chuck and the like) in the PLC program of each travelling crane cannot be completely consistent. When any one main charging crane is abnormal or fails, hardware engineers are required to modify at least two charging crane PLC controller programs to ensure that each charging crane after replacement automatically operates. Conventionally, the operating conditions of all replaceable charging carriages are considered in each charging carriage PLC controller program, which in turn leads to two disadvantages: on one hand, the program logic is abnormally complex, and on the other hand, the program storage space of the PLC is required to be large enough. Initial debugging is also difficult.
Under the condition that the charging capacity of the charging crane is far greater than the smelting capacity of a smelting furnace, most of the charging cranes are production lines with a plurality of smelting furnace mouths, and in order to save cost investment, on the premise of ensuring that the charging tempo meets the requirements, one charging crane is usually adopted and corresponds to a plurality of furnace platform transfer vehicles to carry out automatic charging.
Under the condition that the smelting capacity of the smelting furnace is far larger than the charging capacity of a charging travelling crane, most of the smelting furnaces are production lines of a smelting furnace mouth. At the moment, two charging travelling cranes are generally needed to perform parallel cross operation and charge the same furnace platform transfer trolley.
In the two non-conventional application situations, how to convert the charging travelling crane into a single furnace platform transfer trolley corresponding to a single charging travelling crane after self-simple scheduling under the condition of limited hardware resources and inconvenient programming language of the charging travelling crane PLC controller is a great challenge for hardware engineers.

Furthermore, the detailed execution information, the execution mode and the like of the task are called from the corresponding partition of the data storage area by the identification field of the task, so that the configured transfer equipment can smoothly complete the current task.
Furthermore, each transfer device is a rail device running on one guide rail and is provided with a standby transfer device, and the task allocation method comprises the following steps:
if the transfer equipment with the fault is adjacent to the standby transfer equipment, configuring the information data of the task of the standby transfer equipment into the information data of the task of the transfer equipment with the fault, and enabling the standby equipment to be put into operation instead of the fault equipment;
if the faulted transfer equipment is alternated with the standby transfer equipment, namely at least one transfer equipment which normally runs is arranged between the faulted transfer equipment and the standby transfer equipment, the task of the normally running transfer equipment adjacent to the standby equipment is allocated to the standby transfer equipment, the empty information data of the task of the normally running transfer equipment is allocated to the information data of the task of the faulted transfer equipment, and the transfer equipment until the fault is formed is replaced in sequence; that is, the transfer equipment that breaks down certainly begins to allocate the task of adjacent transfer equipment to the transfer equipment and the reserve transfer equipment of reserve transfer equipment place orientation in proper order to the task of the transfer equipment that realizes breaking down can be normally carried out, has avoided the stagnant problem of production that the transfer equipment breaks down and causes.
