[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a transport device, and is particularly effective when applied to a transport device that travels at a high position (ceiling etc.) away from the ground.

[0002]

[Prior art]

 There is an overhead traveling carriage 1 as shown in FIG. 3 as one that travels along the ceiling in the carrier device. The overhead traveling carriage 1 includes a traveling mechanism 10 and a lifting mechanism 20. When a traveling motor (not shown) of the traveling mechanism 10 is driven, the vehicle travels along a rail 30 provided on the ceiling. When a lifter motor (not shown) of the elevating mechanism 20 is driven, the lifter belt 21 is wound and unwound to move the transfer mechanism 22 up and down, and a motor (not shown) of the transfer mechanism 22 is driven so that the locking portion 23 is released. Retract in the direction of arrow A.

The operation panel 11 includes a power switch 11a, a start switch 11b, a stop switch 11c, and the like. Further, the overhead traveling carriage 1 includes a battery, a control power supply unit, a controller and the like.

FIG. 4 shows a conventional electric system of the overhead traveling carriage 1. In the figure, 40 is a battery, 41 is a noise filter, 42 is a control circuit section, 43 is a controller (including CPU, I / O, and servo driver), 44 is a main contactor, M is a motor (running motor, lifter motor, etc.). ).

When the power switch 11a is turned on, a control voltage is applied from the control power supply section 42a of the control circuit 42 to the controller 43 to activate the CPU, and then the main contactor 44 is turned on by a command from the control circuit 42. . When the start switch 11b is turned on in this state, electric power is supplied to the motor M via the servo driver. In this state, for example, the forward / reverse rotation / stop / rotational speed control of the motor is performed according to the program of the CPU, and the overhead traveling carriage 1 operates according to the program. When the operation was stopped, the stop switch 11c was pressed to stop the power supply to the motor M, and then the power switch 11a was opened to lower the control voltage. When the control voltage drops, the main contactor 44 automatically opens.

[0006]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional technique, when the rail 30 is at a high position, the driver must climb a ladder or the like to operate the switches 11a, 11b, 11c, which is dangerous.

The present invention has been made in view of the above-mentioned conventional art, and an object of the present invention is to provide a carrier device in which a control power source can be turned on and off by remote control.

[0008]

[Means for Solving the Problems]

 The configuration of the present invention which solves the above-mentioned problems includes a battery, a control circuit which outputs a control voltage when power is supplied from the battery, and a controller which controls a motor drive according to an operation command when the control voltage is input. In a transport device equipped with a motor that drives the transport device body along rails by being driven and controlled by a controller, a remote control transmitter that outputs a control power ON / OFF command is provided separately from the transport device body. It is equipped with a remote control receiver that receives control power ON / OFF commands, a power switch interposed between the battery and the control circuit, and a remote control receiver when the power switch is turned on. When the control power ON command is received, the battery power is sent to the control circuit, and when the power switch is turned on, the remote control receiver When receiving the control power OFF command is characterized in that a relay circuit to cut off the power supply to the control circuit from the battery.

[0009]

[Action]

 According to the present invention, when the power switch is turned on, when the remote control transmitter sends a control power ON command to the remote control receiver, the control voltage is sent from the control circuit to the controller to activate the control. When a power-off command is sent, the control voltage supply is cut off and the system enters a stopped state.

[0010]

【Example】

 Embodiments of the present invention will be described below in detail with reference to the drawings. The parts having the same functions as those of the prior art are designated by the same reference numerals, and the duplicated description will be omitted.

As shown in FIG. 1, in the present embodiment, a remote control transmitter 50 that outputs an ON / OFF command of a control power source by being gripped and operated by a driver on the ground is provided, and an overhead traveling carriage is provided. 1 is equipped with a remote control receiver 51 for receiving control power ON / OFF commands.

FIG. 2 shows an electric system of the overhead traveling carriage 1 according to the embodiment. In FIG. 2, R1 is the coil of the first electromagnetic relay, r1 is its contact (A contact), R2 is the coil of the second electromagnetic relay, r2 is its contact (B contact), and R3 is the coil of the third electromagnetic relay. , R3-1 and r3-2 are their contacts (A contacts). The contact point r3-2 is connected between the power switch 11a and the control circuit 42. The remote control receiver 51 excites the coil R1 when receiving the control power supply ON command from the remote control transmitter 50, and excites the coil R2 when receiving the control power supply OFF command.

In this embodiment, once the power switch 11a is turned on, the control power can be turned on and off only by remote control of the remote control transmitter 50. That is, when the control power source ON command is output from the remote control transmitter 50, the coil R1 is excited and the contact r1 is closed. As a result, the coil R3 is excited and the contacts r3-1 and r3-2 are closed. The energized state of the coil R3 is self-maintained by closing the contact point r3-1. When the contact r 3-2 is turned on, a control voltage is sent from the control power supply 42a of the control circuit 42 to the controller 43, and then the main contactor 44 is turned on.

When the control power supply OFF command is output from the remote control transmitter 50 while the control voltage is applied and the main contactor 44 is turned on, the coil R2 is excited and the contact r2 is opened. When the contact r2 is opened, the coil R3 is de-excited and the contacts r3-1 and r3-2 are opened. Opening of the contact r3-1 eliminates the self-holding of the coil R3, and opening of the contact r3-2 eliminates the control voltage output from the control power supply 42a and opens the main contactor 44.

Thus, the control power supply can be turned on and off only by operating the remote control transmitter 50. If the power switch 11a is opened, the control power supply cannot be turned on or off by the remote control transmitter 50 as a matter of course. Therefore, the power switch 11a is opened when it is not used for a long period of time.

It should be noted that other keys of the remote control transmitter can be used to change the setting of the traveling program number of the traveling vehicle or to enable manual operation.

[0017]

[Effect of device]

 According to the present invention as described in detail with reference to the above embodiments, since the control power can be turned on and off remotely by operating the remote controller, it is not necessary to climb to a high position even if the rail is at a high position, which is safe.
