Abstract

A control panel of a machining tool includes a measurement unit measuring a temperature and a humidity involved with an atmosphere inside the control panel, an adjustment unit adjusting the temperature and the humidity, and an atmosphere control unit controlling an atmosphere inside the control panel by controlling the adjustment unit. Since the atmosphere control unit receives electric power supplied from a system separated from a power supply supplying electric power to the machining tool, it is possible to protect various electronic devices inside the control panel by measuring and adjusting the atmosphere inside the control panel even when the machining tool power supply is not turned on.

Claims

1. A machining tool, comprising:

a control panel housing an electronic device including a machining tool controller; and

a user interface operating the machining tool,

wherein the control panel includes

a temperature sensor measuring an atmosphere temperature inside the control panel;

a temperature adjustment unit adjusting the atmosphere temperature inside the control panel,

a humidity sensor measuring an atmosphere humidity inside the control panel,

a humidity adjustment unit adjusting the atmosphere humidity inside the control panel,

an atmosphere controller controlling an atmosphere inside the control panel, and

an atmosphere-controlling power supply supplying electric power to the temperature sensor, the humidity sensor, the temperature adjustment unit, the humidity adjustment unit, and the atmosphere controller, independently from a power supply of the machining tool,

wherein the atmosphere controller is connected to the machining tool controller to communicate with the machining tool controller,

wherein the atmosphere controller includes

a storage storing a temperature command and a humidity command respectively correlated with a temperature and a humidity, and

a command output unit extracting the temperature command and the humidity command stored in the storage based on the temperature and the humidity respectively measured by the temperature sensor and the humidity sensor to output the extracted temperature command and the extracted humidity command, and

wherein the user interface is connected to the machining tool controller via a first communication line to check the measured temperature and the measured humidity and to change the temperature command and the humidity command of the atmosphere controller.

2. The machining tool according to claim 1,

wherein the control panel further includes a concentration sensor measuring an oil mist concentration inside the control panel and a concentration adjustment unit adjusting the oil mist concentration inside the control panel,

wherein the atmosphere-controlling power supply further supplies electric power to the concentration sensor and the concentration adjustment unit in addition to the temperature sensor, the humidity sensor, the temperature adjustment unit, the humidity adjustment unit, and the atmosphere controller,

wherein the storage stores the temperature command, the humidity command, and an oil mist concentration command respectively correlated with the temperature, the humidity, and the oil mist concentration, and

wherein the command output unit extracts the temperature command, the humidity command, and the concentration command stored in the storage based on the temperature, the humidity, and the oil mist concentration measured by the temperature sensor, the humidity sensor, and the concentration sensor, and outputs these extracted commands.

3. The machining tool according to claim 1,

wherein the control panel further includes a measurement information storage storing measurement information measured by the temperature sensor and the humidity sensor, and

wherein the machining tool controller receives the measurement information measured by the temperature sensor and the humidity sensor and stores the measurement information in the measurement information storage.

4. The machining tool according to claim 2,

wherein the control panel further includes a measurement information storage storing measurement information measured by the temperature sensor, the humidity sensor, and the concentration sensor, and

wherein the machining tool controller receives the measurement information measured by the temperature sensor, the humidity sensor, and the concentration sensor and stores the measurement information in the measurement information storage.

5. The machining tool according to claim 1, wherein the user interface is connected to the machining tool controller via the first communication line and connected to the atmosphere controller via a second communication line to check the measured temperature and the measured humidity and to change the temperature command and the humidity command of the atmosphere controller.
