DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, with reference to FIGS. 1, 2, and 3 (and 4), a description will be given of an input device of a machine tool and a machine tool according to an embodiment.

[0019] Similarly to a conventional input device, a machine tool T of the present embodiment includes, for example, an input device 2 that is provided with a CNC 3, an operation panel 4, a key 5, a rotary switch 6, a push button switch 7, etc., exposed on a machine surface T1, and that is disposed to be incorporated in the machine tool T (refer to FIGS. 2, 3, and 4). For example, the input device 2 is a device for inputting a character string to the machine tool 1 or for inputting a start signal.

[0020] As shown in FIG. 1, in the input device 2 of the machine tool of the present embodiment, the operation panel 4 (operation panel unit) includes: a printed circuit board 11 that has a rectangular plate shape in a plan view, includes a non-metallic main body, and includes a plurality of resin keys mounted thereto; a substrate mounting member 9 that has a plate shape in a plan view, includes a plurality of key holes 8 into which the plurality of keys 5 is to be inserted, respectively, and is disposed to be laminated on the front face side of the printed circuit board 11 in a manner in which the plurality of keys 5 is inserted and fit into the plurality of key holes 8 from the back face side; and a resin key sheet 10 (coating member) that has a rectangular shape in a plan view, and disposed to be laminated on the front face side of the substrate mounting member 9 in a manner covering the front surface of the substrate mounting member 9 and the plurality of keys 5.

[0021] Furthermore, a non-contact IC tag reader 1 (non-contact reader) is incorporated in the input device 2 of the machine tool of the present embodiment.

[0022] More specifically, the non-contact IC tag reader 1 of the present embodiment is mounted on the printed circuit board 11 of the operation panel 4 of the input device 2 and connected to a power supply formed on the printed circuit board 11 and wiring for communication for securing power and communication performance, and is provided to be incorporated in the operation panel 4 of the input device 2.

[0023] Although the substrate mounting member 9 of the operation panel 4 is a sheet metal, in the input device 2 of the present embodiment, at least the region of a portion where the printed circuit board 11, the substrate mounting member 9, and the key sheet 10 overlap with the non-contact IC tag reader 1 mounted on the printed circuit board 11 in the stacking direction is configured as a non-metal (for example, resin) member 12.

[0024] Furthermore, in the input device 2 of a machine tool of the present embodiment including the above-described configuration, information is exchangeable between the non-contact IC tag reader 1 incorporated in the input device 2 and the IC tag held by an operator such as a worker (operator).

[0025] Examples of the information include information of components, information of a workpiece 15, information of a tool (tool 18), information of the operator, and the like. Furthermore, it may be configured to provide a function for enabling changing the operable range by the operator, a function for associating an executed machining program with an operator, a function for saving a machining program or a machine setting by the operator, and automatically retrieving it by the operator so that the information relating to these functions can be communicated. With such a configuration, it is possible to identify and manage an executor of the machining program by, for example, allowing the operator to perform only the startup and allowing an administrator to further change a parameter. This enables the construction of a more sophisticated management system of the machine tool.

[0026] Furthermore, in the input device 2 of a machine tool according to the present embodiment, the non-contact IC tag reader 1 is provided inside the operation panel 4. This configuration eliminates the need for separately securing an installation location of the non-contact IC tag reader 1 on the machine surface T1, thereby allowing for fewer restrictions in the machine configuration, machine structure, and machine design.

[0027] By providing the non-contact IC tag reader 1 inside the input device 2 (a space in which environmental resistance is taken into consideration), it is not necessary to demand environmental resistance of the device 1, furthermore, there is no risk of hitting the workpiece 15, a tool, the jig 16, etc. Therefore, it is possible to eliminate the need to construct a robust structure as conventionally. This makes it possible to realize a cost reduction and size reduction.

[0028] In the input device 2 of a machine tool of the present embodiment, by mounting the non-contact IC tag reader 1 on the printed circuit board 11, the non-contact IC tag reader 1 is connected to a power supply, wiring for communication, etc., provided on the printed circuit board 11, and thus, the electrical power, communication performance, etc. can be easily and suitably secured.

[0029] In the input device 2 of the machine tool of the present embodiment, by making the portion of the substrate mounting member 9 overlapping with the non-contact IC tag reader 1 of the operation panel 4 in the stacking direction and the key sheet 10 with a non-metallic member (composed of a non-metallic material), it is possible to suitably ensure the communication performance with the IC tag held by an operator or the like, even if the non-contact IC tag reader 1 is incorporated in the input device 2.

[0030] Although one embodiment of the input device of the machine tool and the machine tool has been described above, the present invention is not limited to the above-described one embodiment, and can be appropriately modified within a scope not departing from the spirit thereof.

[0031] For example, in the present embodiment, although the non-contact reader is the non-contact IC tag reader 1, in a case in which the information can be exchanged in one direction or in two directions without contact, the non-contact reader may be another non-contact reader such as an RFID.

[0032] Furthermore, as shown by the broken line in FIG. 1 (reference numeral 1, reference numeral 12), the installation position of the non-contact reader 1 need not be particularly limited. Furthermore, in a case in which the non-contact reader 1 is incorporated in the input device 2, the non-contact reader 1 need not be limited to being disposed and mounted on the substrate 11, and so long as the non-contact reader 1 is disposed inside the input device 2 and information is communicable, the non-contact reader 1 may be disposed anywhere inside of the CNC 3, for example.

[0033] Furthermore, as shown in FIGS. 2 and 3, instead of incorporating the non-contact reader 1 into the input device 2, the non-contact reader 1 may be provided inside the machine tool 1, for example, near the table 17 as shown in FIG. 2, or near the tool 18 as shown in FIG. 3. In this case, for example, an IC tag is attached to the workpiece 15, the jig 16, the tool 18, or a replacement part, the non-contact IC tag reader 1 provided inside the machine tool T reads information of the IC tag attached to the workpiece 15, the jig 16, the tool 18, or the replacement part delivered on the table 17, thereby suitably performing operation management, equipment management, etc. This makes it possible to increase the efficiency and rationalization of machining operations, equipment management, etc. It should be noted that, in such a case of providing the non-contact reader 1 inside the machine tool T, a non-metal member (non-metallic material) is disposed around the non-contact reader 1.
