Abstract
A working machine includes a cutting machine, a tool holder which can be installed to or removed from the spindle of the cutting machine, a transmission and reception mechanism installed in the tool holder, and a controller for performing radio communication with the transmission and reception mechanism via electromagnetic waves. An antenna configuring the transmission and reception mechanism is installed in a radio wave transparent material and a cover material at a distance from the circumference of the tool holder for radio communication between the tool holder and the external controller.
Claims13
A working machine comprising:
- a tool holder in which a tool is mounted;
- a transmission and reception mechanism installed to said tool holder;
- and
- a controller which performs radio communication with said transmission and reception mechanism on electromagnetic waves;
- wherein said transmission and reception mechanism includes:
- an antenna located at a certain distance from electrically conductive parts forming said tool holder;
- and
- a radio wave transparent material intervening between said antenna and said electrically conductive parts.
A radio communication means between a tool holder for mounting a tool and an external controller of a working machine comprising:
- a controller transmitting an electromagnetic wave to a tool holder to supply predetermined operation signals to said tool holder;
- and
- said tool holder transmitting back an electromagnetic radio wave having received said operation signals from said controller for the confirmation of the supply of said predetermined operation signals.
A radio communication means between a tool holder for mounting a tool and an external controller of a working machine comprising:
- sender means for transmitting a basic carrier electromagnetic wave and an indentifying signal wave simultaneously, and a receiver for receiving the indentifying signal wave and the basic carrier electromagnetic wave and performing a predetermined operation corresponding to the received indentifying signal wave only when both said basic carrier electromagnetic wave and said indentifying signal wave are received.
