Claims15
A molding machine comprising:
- a cylinder;
- a screw built in the cylinder;
- a telemeter;
- and
- a base unit arranged at a position facing the telemeter, the telemeter and the base unit not being connected by wiring,
- wherein the telemeter includes a first sensor and a second sensor for detecting a state of the screw,
- wherein a housing of the telemeter is composed of a pair of housing portions made of a non-conductor,
- wherein the telemeter is attached to the screw by sandwiching the screw by the pair of housing portions outside the cylinder,
- wherein the first sensor is arranged in one of the pair of housing portions,
- wherein the second sensor is arranged in the other of the pair of housing portions,
- wherein the first sensor and the second sensor are arranged at positions symmetrical to each other with respect to a rotation center axis of the screw,
- wherein the first and second sensors are pressed to the screw so as to be in direct contact with the screw,
- wherein a power receiving coil, a processor, and a data transmitting coil are embedded in the housing of the telemeter or are arranged in concave portions formed in the housing of the telemeter, and
- wherein the base unit includes a power transmitting coil configured to wirelessly supply power from an external power source to the power receiving coil of the telemeter, a data receiving coil configured to wirelessly receive data from the data transmitting coil of the telemeter, and a processor configured to process and transmit the received data to a data receiving device external to the molding machine.
