  • Publication number: 20200301396
    Abstract: Provided is an input device of a machine tool and a machine tool that can eliminate the need for separately securing an installation location of a non-contact reader on a machine surface, thereby allowing for fewer restrictions in the machine configuration, machine structure, and machine design. Disclosed is an input device of a machine tool or machine tool that includes a non-contact reader therein. The input device includes an operation panel unit that includes: a substrate to which a key is mounted; a substrate mounting member that includes a key hole into which the key is to be inserted and disposed to be laminated on a front face side of the substrate; and a covering member that is disposed to be laminated on a front face side of the substrate mounting member so as to cover a surface of the substrate mounting member and the key, in which the non-contact reader is mounted on the substrate.

  • Patent number: 10720872
    Abstract: A motor control device includes a rectifier which converts AC power into DC power and outputs it to a DC link, an inverter which converts the DC power of the DC link into AC power for each motor and outputs it, an AC voltage detection unit which detects an AC voltage value on the AC input side of the rectifier, a state determination unit which determines that a voltage dropped state has been set when the AC voltage value is smaller than a certain specified voltage and that a normal state has been set when the AC voltage value is equal to or larger than the specified voltage, and an output control unit which controls each motor in accordance with the amount of voltage drop with respect to the specified voltage of the AC voltage value when the state determination unit determines that the voltage dropped state has been set.

  • Patent number: 10002514
    Abstract: A machine tool has the function of monitoring the sealing performance of a control panel. The machine tool measures temperature and humidity inside the control panel, calculates a vapor amount from the measured results, and stores the vapor amount. A vapor amount change ratio is calculated based on a currently calculated vapor amount and a previously calculated and stored vapor amount. An alert is announced when the calculated vapor amount change ratio is greater than or equal to a specific value.

  • Patent number: 9946249
    Abstract: A control device of a machining tool with power consumption reduction function includes an execution unit configured to execute control of devices using parameter extracted from a parameter set storage unit, based on a selected priority mode and operation condition of the machining tool. At least one parameter set stored in the parameter storage unit is set with a parameter corresponding to the heating device having a value for making the heating device in an on state and a parameter corresponding to the cooling device having a value for making the cooling device in an on state.

  • Publication number: 20140353130
    Abstract: An electrical circuit switching device includes a housing body including therein a circuit breaker for breaking/energizing an electrical circuit, and a housing door including a handle for operating the circuit breaker. A switch operating unit for driving a circuit switching unit of the circuit breaker includes a lock that can engage/disengage with/from a coupling part of the handle. The coupling part engages with the lock when the housing door is closed, and the circuit breaker can be operated only in this state via the coupling part.
