Air filter device of industrial machine
An air filter device of an industrial machine in which an air filter is arranged in a filtered portion of the industrial machine is provided, the air filter device includes: a first operation unit which transports the long air filter toward the filtered portion; a second operation unit which collects the air filter transported from the first operation unit and used in the filtered portion; and a control unit which controls the drive of the first operation unit and the second operation unit and the control unit includes a first determination unit which determines whether or not the air filter in the first operation unit is about to run out or runs out, and outputs, when the first determination unit determines that the air filter is about to run out or runs out, a signal indicating that the air filter needs to be replaced.
1. An air filter device of an industrial machine, the air filter device comprising:
a filtered portion;
an air filter that is arranged in the filtered portion;
a first operation unit that includes a first rotation axis around which the air filter is wound and transports the air filter toward the filtered portion, the first operation unit including a first motor that drives rotation of the first operation unit;
a second operation unit that includes a second rotation axis and collects the air filter transported from the first operation unit and used in the filtered portion on the second rotation axis, the second operation unit including a second motor that drives rotation of the second operation unit;
a control unit configured to control drive of the first motor of the first operation unit and drive of the second motor of the second operation unit; and
a dirt removal unit
comprising a first dirt removal unit that includes an air blower and a second dirt removal unit that includes a cleaning chamber storing cleaning fluid to remove the dirt by a method different from a method of the first dirt removal unit, the air filter is transported to the first dirt removal unit,
the air filter device further includes an inspection unit configured to inspect, with a sensor, a state of the dirt of the air filter after the dirt is removed with the first dirt removal unit,
the control unit is configured to determine whether or not the state of the dirt of the air filter inspected with the inspection unit exceeds a preset state of the dirt, and
the control unit is configured such that when it determines that the preset state of the dirt is exceeded, the control unit is configured to send a signal such that the air filter is transported to the second dirt removal unit.
2. The air filter device of the industrial machine according to claim 1 ,
wherein the control unit is configured to determine whether or not the air filter in the first operation unit or the second operation unit is about to run out or runs out, and
the control unit is configured such that when it determines that the air filter in the first operation unit or the second operation unit is about to run out or runs out, the control unit is configured to control the drive of the first operation unit and the second operation unit by stopping the operation of one of the first motor and the second motor and rotating the other of the first motor and the second motor so as to transport the air filter in an opposite direction.
3. The air filter device of the industrial machine according to claim 1 ,
wherein the control unit is configured such that when it determines that the preset state of the dirt is exceeded, the control unit is configured to output a signal indicating that the air filter needs to be replaced and to stop operation of the air filter device.
4. The air filter device of the industrial machine according to claim 1 , wherein the control unit is configured to determine whether or not an operating time preset in the industrial machine is exceeded, and
wherein the control unit is configured such that when it determines that the operating time is exceeded, the control unit is configured to output a signal indicating that the air filter needs to be replaced and to stop operation of the air filter device.
5. The air filter device of the industrial machine according to claim 1 , wherein the dirt removal unit removes dirt on a transport path of the air filter between the first operation unit and the filtered portion and dirt on a transport path of the air filter between the second operation unit and the filtered portion.
