The following is a more detailed description of the present invention, and the modes for implementing the present invention will be described in accordance with the accompanying drawings.

Embodiment 1.

In the first embodiment below, industrial equipment is assumed to be various equipment installed in a factory or the like.

FIG. 1 is a diagram showing an example of the appearance of the industrial machine 1 according to the first embodiment. Here, the perspective view of the industrial machine 1 is shown in FIG.

In Embodiment 1, the industrial machine 1 is installed on a floor 3 of a factory or the like, and is connected to an external power source, and the external power source receives power from the supplier. The external power supply system includes a plurality of devices connected to the industrial device 1. If a plurality of devices are connected to a common external power source, noise from other devices is mixed into the body of the industrial device 1 through the common external power source, and the mixed noise flows out to the operator through the touch panel 12 described later, thereby There is a possibility that an erroneous operation of the touch panel 12 may be caused.

The industrial machine 1 includes a housing 11, a touch panel 12, and a sheet conductor (hereinafter referred to as “sheet conductor 13”).

The frame 11 is formed of metal and is electrically connected to the ground 2.

However, in the first embodiment, the present system of the industrial machine 1 refers to elements other than the touch panel 12 among the elements constituting the industrial machine 1. The elements constituting the industrial machine 1 other than the touch panel 12 are the housing, Source circuit, control circuit, servo motor, etc.

The touch panel 12 is a capacitive touch panel.

The touch panel 12 is disposed on the frame body 11 and is electrically connected to the frame body 11. The touch panel 12 and the frame body 11 are, for example, a frame body (not shown) included in the touch panel 12 is screwed to the frame body 11 to make a metal connection. Among them, this is only an example, and the touch panel 12 may be provided on the frame body 11 by an appropriate method and electrically connected to the frame body 11.

In the first embodiment, as shown in FIG. 1, the touch panel 12 is provided on one of a plurality of surfaces included in the housing 11.

The sheet-like conductor 13 is electrically connected to the frame 11 and is provided for an operator of the touch panel 12 to make contact.

In addition, the sheet-like conductor 13 is provided on the floor 3 on the side where the touch panel 12 is provided with respect to the housing 11.

In the first embodiment, the sheet-like conductor 13 is assumed to be directly connected to the housing 11. If the sheet-shaped conductor 13 is directly connected to the frame body 11 and electrically connected to the frame body 11, the connection method of the sheet-shaped conductor 13 and the frame body 11 may be formed as an appropriate method.

In the first embodiment, the sheet-like conductor 13 is provided on the floor 3 on the side where the touch panel 12 is provided with respect to the frame 11.

The operator 4 rides on the sheet-like conductor 13 and operates the touch panel 12 on the sheet-like conductor 13.

The area of the sheet-like conductor 13 can be set to an appropriate area. However, at least the operator 4 does not barely operate only the area of the touch panel 12 in a state of being carried on the sheet-like conductor 13.

Here, FIG. 2 is a diagram for explaining the principle of preventing an erroneous operation of the touch panel 12 by the sheet-like conductor 13 in the industrial device 1 according to the first embodiment. FIG. 2A is a diagram for explaining a noise flow in a general industrial device (hereinafter, referred to as a “sheet-unconnected device”) to which a sheet-shaped conductor 13 is not connected, and FIG. 2B is a diagram illustrating a sheet-shaped conductor connected Figure of noise flow in industrial machine 1 of 13. Among them, the sheet unconnected device shown in FIG. 2A is different from the industrial device 1 shown in FIG. 2B only in whether or not the sheet conductor 13 is connected, and the other configurations are the same.

For example, in the sheet unconnected machine shown in FIG. 2A, if noise occurring outside the sheet unconnected machine is mixed into the ground 2, the noise is mixed into the body of the sheet unconnected machine, and the operator 4 A relative potential difference occurs between the sheet and the unconnected machine.

In a state where a relative potential difference occurs between the operator 4 and the sheet-unconnected device, if the operator 4 touches the touch panel 12, the coupling capacitance between the touch panel 12 and the operator 4 (see FIG. 2A) C _1), and the operator coupling capacitor (refer to FIG. 2A and the ground between 4 ₂ C 2) of the current path of current flow noise (refer to 201 of FIG. 2A).

As a result, in the touch panel 12, due to the noise current, erroneous sensing of the position touched by the operator 4 may occur. That is, the touch panel 12 performs an incorrect operation.

There is no relative potential difference between the person 4 and the industrial machine 1.

As a result, in a state where noise generated outside the industrial machine 1 is mixed into the ground 2 and the noise is mixed into the body of the industrial machine 1, even if the operator 4 touches the touch panel 12, Noise current does not flow in the current path of the coupling capacitor (C _{3 in} FIG. 2B) between the control panel 12 and the operator 4, and the coupling capacitor between the operator 4 and the sheet-shaped conductor 13, preventing the operator 4 from False sensing of the position encountered. That is, an erroneous operation of the touch panel 12 can be prevented.

Therefore, the operator 4 is free with both hands, and does not impair the operability of the touch panel 12 by the operator 4.

Specifically, for example, even if the operator 4 holds the tablet with one hand, the touch panel 12 can be operated in a state where the operator 4 and the frame 11 and the touch panel 12 are capacitively coupled with a low impedance.

In addition, in the industrial machine 1 according to the first embodiment, the sheet-shaped conductor 13 is electrically connected to the housing 11, so that a relative potential difference between the operator 4 and the industrial machine 1 does not occur.

In the industrial machine 1, the sheet-like conductor 13 is connected only to the housing 11 Therefore, the industrial machine 1 does not need to include a special structure such as a port for electrically connecting the touch panel 12 and the sheet-like conductor 13 in advance.
