[Industrial applications]

 The present invention relates to a remote control device for manually controlling an overhead traveling carriage.

[0002]

[Prior art]

 Conventionally, a system for transporting a load by an overhead traveling carriage is known. The main body of the overhead traveling carriage travels while being guided by rails provided on the ceiling, and an elevating platform is provided on the main body so that it can be raised and lowered. The traveling along the rails of the overhead traveling carriage and the lifting operation of the lifting platform are usually controlled by a computer, but the manual operation is performed by a remote control device.

Now, such a remote control device usually has a switch button protruding from the surface of the main body, and is configured to operate only when the switch button is pressed. That is, the remote control device does not have a power switch, and the battery provided in the main body is hardly consumed except when the switch button is pressed.

[0004]

[Problems to be solved by the device]

 However, if the switch button protrudes from the surface of the remote control device in this way, when the device body is placed on the floor or the like with this surface facing downward, the switch button is pressed by the weight of the remote control device, This may cause the remote control device to operate and consume the battery. In order to prevent such a problem from occurring, it is possible to provide a flat switch on the surface of the remote control device body, but the flat switch has a problem in that it is inferior to the switch button in terms of operability. If a dedicated power switch is provided, the power switch must be turned on and off every time the remote control is operated, which makes the remote control operation troublesome.

The present invention provides a remote control device in which the battery is not wasted and the operability is not impaired even when the surface of the remote control device is placed downward on the floor. It was made for the purpose of obtaining.

【Example】

 The present invention will be described below with reference to illustrated embodiments. FIG. 1 shows an example of the configuration of the overhead traveling carriage 11. The main body 12 of the overhead traveling carriage 11 travels while being guided by rails 13 provided on the ceiling, and an elevation platform 14 is provided below the main body 12. The elevating table 14 is suspended from the main body 12 by four steel belts 15, and the steel belts 15 are raised or lowered by winding or releasing the steel belts 15. Two chuck mechanisms 21 are provided on the lower surface of the lifting table 14. These chuck mechanisms 21 grab and suspend a bucket (luggage) 31 containing, for example, a silicon wafer.

The traveling of the overhead traveling carriage 11 and the elevating operation of the elevating table 14 are usually performed under the control of a computer, but can also be performed manually. This manual operation is performed, for example, by optical communication, that is, by pointing the remote control device 41 to a light receiving portion (not shown) of the main body 12 and pressing a predetermined switch button 42.

FIG. 2 shows the external appearance of the remote control device 41 of the first embodiment, and the device body 43 has a flat plate shape. A plurality of switch buttons 42 corresponding to the operation contents are projected from the surface 43a of the device body 43. That is, these switch buttons 42 are a button for switching the operation of the overhead traveling carriage 11 between an automatic mode and a manual mode, a button for moving the overhead traveling carriage 11 forward or backward, and raising or lowering the lifting platform 14. And a button for opening and closing the chuck mechanism 21.

A battery is provided in the device main body 43, and power is supplied to the control circuit of the remote control device 41 to operate only when one of the switch buttons 42 is pressed. Move up and down. In other words, the remote control device 41 does not have a power switch, and the switch button 42 also serves as a power switch.

A power-off switch 44 is provided on the surface 43 a of the apparatus body 43 so as to project therefrom. The power-off switch 44 is provided to shut off the connection between the battery and the control circuit, and the protrusion amount of the power-off switch 44 from the surface 43a is larger than that of the switch button 42. Further, the force required to push down the power off switch 44 may be smaller than the own weight of the apparatus main body 43.

Therefore, as shown in FIG. 3, when the apparatus main body 43 is placed on the floor F, for example, with the surface 43 a facing downward, the power-off switch 44 is operated by the self-weight of the remote control device 41. It is pressed toward the main body 43 side, thereby electrically disconnecting the battery and the control circuit. That is, the power consumption of the battery is stopped, and even if the switch button 42 is pressed by the floor surface F, the battery is not consumed.

As described above, in this embodiment, since the power-off switch 44 is added without changing the configuration of the switch button 42, the apparatus main body 43 is placed downward on the floor surface F. The remote control device 41 is configured not to operate even when it is pressed. That is, according to this embodiment, the operability of the switch button 42 protruding from the surface 43a can be maintained, and the abrupt operation of the remote control device 41 can be avoided to prevent wasteful consumption of the battery.

FIG. 4 is a block diagram of the remote control device 41 of the second embodiment. In this embodiment, a direction detector 45 is provided to detect whether or not the surface 43a (FIG. 2) of the device body 43 faces downward. The direction detector 45 has, for example, a weight movably provided in a linear groove, the position of the weight changes according to the posture of the apparatus main body 43, and a signal corresponding to the position of this weight is provided. Is output. When the direction detector 45 outputs a signal indicating that the surface 43a faces downward, the power-off switch 48 provided between the control circuit 46 and the battery 47 opens, and the control circuit 4 6 and the battery 47 are electrically disconnected. At other times, the power off switch 48 is closed and the control circuit 46 is supplied with power from the battery 47.

As described above, in the second embodiment, when the surface 43a of the remote control device 41 is directed downward, the power off switch 48 is opened, and the control circuit 46 and the battery 47 are electrically disconnected. With this configuration, the same effect as that of the first embodiment can be obtained.

FIG. 5 is a view showing the outer appearance of the remote control device 41 of the third embodiment. Explaining only the parts different from the first embodiment, projections 49, which are slightly larger than the switch button 42, project from the surface 43a, are provided at the four corners of the surface 43a of the apparatus body 43. In this embodiment, no power off switch is provided.

In the third embodiment, when the remote control device 41 is placed on the floor surface with the front surface 43a facing downward, only the protrusion 49 contacts the floor surface, so that the switch button 42 is moved by the floor surface F. It will not be pressed. Therefore, in such a state, the battery is not consumed, and the same effects as those of the first and second embodiments can be obtained.

As described above, according to each of the above-described embodiments, the remote control device 41 is not laid down on its face, so that the switch button 42 is not pressed to operate the remote control device 41. Therefore, useless consumption of the battery is prevented and the life of the battery can be extended.

In the above embodiment, the place where the remote control device 41 is placed is described as the floor surface F, but this may be the top surface of a desk or the like.
