Background
The working tasks among the cold rolling grinding rollers are mainly the grinding tasks of the surfaces of the working rollers, the intermediate rollers, the supporting rollers and the like of an acid continuous rolling unit, a continuous annealing unit, a hot galvanizing unit, a coating unit and the like; performing surface texturing processing on working rolls of an acid continuous rolling unit, a continuous annealing unit, a hot galvanizing unit, a hot-dip color coating unit and the like; the roller bearings and the bearing seats are disassembled, cleaned, checked, adjusted and assembled.
Production management between traditional grinding roller mainly manages through the management system between the grinding roller (RSMS for short), and the management system main function includes between the grinding roller: new roll receiving, bearing housing and bearing management, roll distribution sending, machine unloading receiving and the like. The grinding roller management system is connected with a grinder server in a lower mode and receives data such as grinding, texturing and the like; the L3 roller system can be connected upwards to transmit the information of consumption, rolling quantity and the like. The existing management system between the grinding rollers only manages and does not control the operation of equipment.
The structural diagram of a traditional grinding roller room management system is shown in a figure 1.
The traditional roll management system between grinding rolls receives roll information (including roll number, roll diameter, roll shape, roughness, roll state (normal roll change or abnormal roll change), rolling time, tonnage, kilometer number and the like) of a lower roll from an upper roll management system, after a roll enters a grinding roll room, a roll is hung on a bearing seat dismounting machine manually, after the bearing seat is dismounted manually, the roll number and the bearing seat number are recorded, and the roll number and the bearing seat number are input into the management system between the grinding rolls manually at a dismounting area terminal. After the roller is manually hung into the Loader area, the storage position number of the roller in which the roller is hung is manually recorded, and then the storage position number is manually input into the management system between the rollers at the terminal of the main operation room. And arranging a production plan manually according to actual conditions of the standby roller and the like and issuing a production instruction manually. After the processing of the roller is finished, a Loader area is manually lifted out, after a bearing seat is completely transferred, the roller number and the bearing seat number are manually recorded, then the roller is manually input and confirmed to be completely matched at a terminal of a dismounting area, and meanwhile, the management system uploads information to the upper computer roller management system.
It is thus clear that management system relies on manual work in a large number in the operation between traditional grinding roller, and degree of automation is low, has influenced production efficiency's promotion.

For example: when the roller is automatically drawn out from the roller changing trolley and is sent into an automatic bearing seat dismounting machine, the RFID reader reads the roller information and the bearing seat information into the IRSC, the roller is sent into an automatic area through the RGV after being automatically dismounted through the bearing seat, the IRSC system issues a production instruction according to information such as the roller condition, and the Loader hangs the roller on a grinding machine or waits on a roller frame beside the grinding machine according to the instruction. And the ground roller is sent into an automatic roller dismounting machine for bearing seat mounting through an IRSC command by hanging an RGV on a Loader. Data exchange with an upper computer (roll management system) is realized through the roll management system.
Whether the main grinding roller room management system of bearing frame management confirms that the bearing will wash according to the bearing frame time of operating the computer, maintain and maintain, grinding roller room management system assigns the instruction and gives the IRSC system, after the IRSC system received the instruction, after the roll change dolly is taken out to the roll, send the roll into special roll stand by RGV and deposit, in order to avoid influencing the line rhythm of production, this kind of roll is hung into the manual operation region through the manual work and is dismantled the bearing frame, the manual work is washd the bearing simultaneously, is maintained and is maintained. After finishing, the roller is still manually hung into a special roller frame, and the roller is sent into a roller changing trolley by an RGV and a drawing trolley.
The equipment required for each process is shown in the following table:
