Belt management system and method
First Claim
1. A belt management system that is formed by a management server that manages belts that are used in a belt conveyor, a terminal that is provided in a location where the belt conveyor is installed, and a data server that is provided in a company that manufactures and sells belts, whereinthe management server is provided with:
- a transceiver unit that receives in time series belt remaining thickness data that shows the thickness of the belt and that is supplied from the terminal at each one of predetermined periods;
a belt lifespan prediction unit that, by writing the belt remaining thickness data in the management database in time series, and reading from the management database the belt remaining thickness data that has been stored in time series, and dividing the difference between the predetermined periods by the usage amount of the belt at each of the predetermined periods, and determining a unit amount of change in the usage amount units, and subtracting from the most recent belt remaining thickness data a management threshold value which shows the thickness of the belt, and dividing the result of this subtraction by the unit amount of change, determines a remaining lifespan that shows the future amount of use until the belt needs to be replaced;
an expenditure database in which a total cost of ownership is written and stored, in belt conveyor units, for each different type of belt, the total cost of ownership including at least belt price, maintenance costs, and electricity cost; and
a total cost of ownership calculating unit that determines a total cost in usage amount units by dividing a sum total of the belt price, the maintenance costs, and the electricity cost that has been stored in the expenditure database by the usage amount, and associating the total cost in usage amount units with the corresponding belt of the belt conveyor and writing and storing the results in the expenditure database,wherein a measuring device that measures the belt remaining thickness data is provided in the belt conveyer,wherein the belt remaining thickness data is either data that has been measured and input into the terminal, or data that is measured by the measuring device and is collected from the measurement device by the terminal.

Abstract
A belt management system of the present invention is formed by a management server (1) that manages belts that are used in a belt conveyor, a terminal (2) that is provided in a location where the belt conveyor is installed, and a data server (3) that is provided in a company that manufactures and sells belts, wherein the management server is provided with: a transceiver unit (10) that receives in time series belt remaining thickness data that shows the thickness of the belt and that is supplied from the terminal at each one of predetermined periods; and a belt lifespan prediction unit (11) that, by writing the belt remaining thickness data in the management database in time series, and reading from the management database the belt remaining thickness data that has been stored in time series, and dividing the difference between the predetermined periods by the usage amount of the belt at each of the predetermined periods, and determining a unit amount of change in the usage amount units, and subtracting from the most recent belt remaining thickness data a management threshold value which shows the thickness of the belt and which is to be used as an indicator for replacement, and dividing the result of this subtraction by the unit amount of change, determines a remaining lifespan that shows the future amount of use until the belt needs to be replaced.

8. A belt management method that causes a belt management system that is formed by a management server that manages belts that are used in a belt conveyor, a terminal that is provided in a location where the belt conveyor is installed, and a data server that is provided in a company that manufactures and sells belts to operate, wherein
the belt management method includes: -
a computer system implementing the steps of; a receiving step in which belt remaining thickness data that shows the thickness of the belt and that is supplied from the terminal is received in time series at each one of predetermined periods; a belt lifespan prediction step in which, by writing the belt remaining thickness data in the management database in time series, and reading from the management database the belt remaining thickness data that has been stored in time series, and dividing the difference between the predetermined periods by the usage amount of the belt at each of the predetermined periods, and determining a unit amount of change in the usage amount units, and subtracting from the most recent belt remaining thickness data a management threshold value which shows the thickness of the belt, and dividing the result of this subtraction by the unit amount of change, a remaining lifespan that shows the future amount of use until the belt needs to be replaced is determined; a recording step wherein a total cost of ownership is written and stored in an expenditure database, in belt conveyor units, for each different type of belt, the total cost of ownership including at least belt price, maintenance costs, and electricity cost; and a calculating step wherein a total cost of ownership calculating unit determines a total cost in usage amount units by dividing a sum total of the belt price, the maintenance costs, and the electricity cost that has been stored in the expenditure database by the usage amount, and associating the total cost in usage amount units with the corresponding belt of the belt conveyor and writing and storing the results in the expenditure database, wherein a measuring device that measures the belt remaining thickness data is provided in the belt conveyor, wherein the belt remaining thickness data is either data that has been measured and input into the terminal, or data that is measured by the measuring device and is collected from the measurement device by the terminal.

9. A belt management method in which data is exchanged between a terminal that is provided at a location where a belt conveyor is installed and a management server that manages the belts used on the belt conveyor, wherein
the belt management method includes: -
a computer system implementing the steps of; a transmitting step in which belt remaining thickness data that shows the thickness of the belt is transmitted by the terminal in time series to the management server after predetermined periods; a receiving step in which, when the remaining lifespan determined by the management server that shows the future amount of use of the belt until it needs to be replaced drops below a usage amount in the predetermined period that has been set in advance, an alarm recommending that the belt be replaced is received by the terminal from the management server; a recording step wherein a total cost of ownership is written and stored in an expenditure database, in belt conveyor units, for each different type of belt, the total cost of ownership including at least belt price, maintenance costs, and electricity cost; and a calculating step wherein a total cost of ownership calculating unit determines a total cost in usage amount units by dividing a sum total of the belt price, the maintenance costs, and the electricity cost that has been stored in the expenditure database by the usage amount, and associating the total cost in usage amount units with the corresponding belt of the belt conveyor and writing and storing the results in the expenditure database, wherein a measuring device that measures the belt remaining thickness data is provided in the belt conveyor, wherein the belt remaining thickness data is either data that has been measured and input into the terminal, or data that is measured by the measuring device and is collected from the measurement device by the terminal. - View Dependent Claims (10, 11, 12)
