Conveyor belt management system
A conveyor belt management system is capable of determining in detail the state of a conveyor belt. A state of the conveyor belt is monitored by a calculation unit based on data of an indicator indicating a status of a belt conveyor device and data of an indicator indicating a use environment of the conveyor belt installed on a belt conveyor device; at least one data from an amount of wear of an upper cover rubber, an impact force acting on the conveyor belt, a tensile force, an indicator indicating a state of a core, and an indicator indicating a state of an endless portion input to the server by the input unit; and a belt specification database and a tolerance range database in which a tolerance range for each of the input items is input in advance per belt specification stored in a storage unit.
1. A conveyor belt management system, comprising:
an input unit including at least one device configured to detect and input an indicator indicating a state of a belt conveyor device installed on site and an indicator indicating a use environment of a conveyor belt at a use site;
an input unit including at least one device configured to detect and input at least one input item from five input items consisting of an amount of wear of an upper cover rubber of the conveyor belt, an impact force acting on the conveyor belt, a tensile force, an indicator indicating a state of a core, and an indicator indicating a state of an endless portion; and
a server into which data of each of the input items are input;
the server comprising a calculation unit including a microprocessor and a storage unit including memory,
the storage unit being configured to store a belt specification database in which specifications of the conveyor belt are input in advance and a tolerance range database in which a tolerance range for each of the input items input into the server per each of the specifications of the conveyor belt is input in advance,
the calculation unit being configured to monitor a state of the conveyor belt based on the data of each of the input items input into the server, the specifications of the conveyor belt input into the belt specification database, and the tolerance range input into the tolerance range database, and
the server being configured to send notice of monitored state of the conveyor belt to an interested party.
2. The conveyor belt management system according to claim 1 , wherein
the indicator indicating the state of the belt conveyor device comprises a conveyance speed of a conveyed object or a conveyance weight per unit time;
the indicator indicating the use environment of the conveyor belt at the use site comprises a value identifying a use environmental temperature and a conveyed object specification;
the indicator indicating the state of the core comprises a gap in a belt width direction between cores arranged side by side;
the indicator indicating the state of the endless portion comprises a bonding length of the endless portion; and
data of each of the indicator indicating the state of the core and the indicator indicating the state of the endless portion are input into the server.
3. The conveyor belt management system according to claim 2 , wherein
a remaining service life of the conveyor belt is calculated by the calculation unit based on the data of the input items input into the server, the specifications of the conveyor belt input into the belt specification database, and the tolerance range input into the tolerance range database; and
the calculation unit monitors the remaining service life of the conveyor belt as one state of the conveyor belt device.
4. The conveyor belt management system according to claim 2 , wherein
an expected service life of the conveyor belt is calculated by the calculation unit before the conveyor belt is installed on the belt conveyor device based on the use environment of the conveyor belt at the use site, the specifications of the conveyor belt input into the belt specification database, and a correlation between the use environment of the conveyor belt and the specifications of the conveyor belt and an actual service life of the conveyor belt determined beforehand.
5. The conveyor belt management system according to claim 1 , wherein
a remaining service life of the conveyor belt is calculated by the calculation unit based on the data of the input items input into the server, the specifications of the conveyor belt input into the belt specification database, and the tolerance range input into the tolerance range database; and
the calculation unit monitors the remaining service life of the conveyor belt as one state of the conveyor belt device.
6. The conveyor belt management system according to claim 5 , wherein
an inventory database into which an inventory amount of replacement conveyor belts for the conveyor belt at the use site or at a stockyard near the use site of the conveyor belt is input is stored in the storage unit;
the server is communicably connected to a customer terminal device; and
the server sends communication notifying of an order period of the replacement conveyor belt or communication prompting order thereof to the customer terminal device based on the inventory amount input in the inventory database and the remaining service life calculated by the calculation unit.
7. The conveyor belt management system according to claim 6 , wherein
an expected service life of the conveyor belt is calculated by the calculation unit before the conveyor belt is installed on the belt conveyor device based on the use environment of the conveyor belt at the use site, the specifications of the conveyor belt input into the belt specification database, and a correlation between the use environment of the conveyor belt and the specifications of the conveyor belt and an actual service life of the conveyor belt determined beforehand.
8. The conveyor belt management system according to claim 5 , wherein
an expected service life of the conveyor belt is calculated by the calculation unit before the conveyor belt is installed on the belt conveyor device based on the use environment of the conveyor belt at the use site, the specifications of the conveyor belt input into the belt specification database, and a correlation between the use environment of the conveyor belt and the specifications of the conveyor belt and an actual service life of the conveyor belt determined beforehand.
9. The conveyor belt management system according to claim 1 , wherein
an expected service life of the conveyor belt is calculated by the calculation unit before the conveyor belt is installed on the belt conveyor device based on the use environment of the conveyor belt at the use site, the specifications of the conveyor belt input into the belt specification database, and a correlation between the use environment of the conveyor belt and the specifications of the conveyor belt and an actual service life of the conveyor belt determined beforehand.
10. The conveyor belt management system according to claim 9 , wherein the calculation unit also calculates an expected service life of a replacement conveyor belt to be used after the conveyor belt at the use site, based on use conditions when the conveyor belt is used at the use site, specifications of the replacement conveyor belt, and input of data of the actual service life of the conveyor belt at the use site which have been input into the belt specification database and updated.
