Abstract
A memory is built in a tool holder to which a working tool such as drill or the like is attached. Various tool information such as kind of tool, dimensions of tool, tool use time, and the like is written into the memory. The tool holder having the memory therein is coupled with an external unit by contactless coupling means which doesn't need any electrical coupling, thereby allowing the tool information to be written into or read out of the memory. The information is transmitted between the memory in the tool holder and the external unit by way of the optical or magnetical coupling. The memory built in the tool holder consists of a non-volatile memory such that the memory content is not erased even if the power supply is shut off.
Claims13
An information processing apparatus of a tool holder to which a working tool to be exchanged by being attached and detached to and from a machine tool by an automatic tool exchanging apparatus is attached,
- wherein said holder itself has therein:
- a memory for storing various information regarding the tool attached to the holder;
- a contactless coupling means for reading and writing the information between said memory and an external unit by way of a serial data transmission;
- and
- a power source means for supplying power sources to said memory and said contactless coupling means;
- wherein said external unit is an independent portable unit, and an information writing unit for writing the information into said memory built in the tool holder is constituted by setting the tool holder into said independent portable unit.
An information processing apparatus of a tool holder to which a working tool to be exchanged by being freely attached to and detached from a machine tool by an automatic tool changer is attached, comprising:
- a nonvolatile memory, provided in said tool holder, for storing various information regarding the tool attached to the holder;
- a contactless coupling means for reading and writing information between said nonvolatile memory and an external unit by a serial data transmission;
- and
- a power source means having a primary side partial transformer and a secondary side partial transformer which are obtained by dividing a power transformer into a primary side and a secondary side, said primary side partial transformer being provided in said external unit and said secondary side partial transformer being provided in said tool holder, and said power source means being constituted in a manner such that an AC voltage is induced in the secondary side partial transformer by an electromagnetic induction coupling of the primary side partial transformer, and a DC voltage which is obtained by regulating said AC voltage by a rectifying and regulating power source is generated, and this regulated DC voltage is supplied to said nonvolatile memory and to the contactless coupling means on the side of said tool holder in said contactless coupling means.
