Description

PORTABLE CONTROL BOX OPERATIONAL CONTROL BOX

The present invention relates to a method and apparatus for controlling a machining apparatus and a transportation apparatus in a safe place by wirelessly connecting a machining apparatus composed of an automobile component assembling robot or a welding robot and a transportation apparatus including a crane or a hoist by a Zigbee- The present invention relates to a portable control box for operating a portable device.

In general, the control box used for controlling and controlling dangerous objects such as assembling robots, welding devices, cranes and hoists is called a control box.

Conventionally, the control box is moved to the left and right work places using a movement guide that moves on the rails when the cranes and hoists are being operated.

If the work area is located on the opposite side from the fixed point of the carrier cable, if the operator moves the control box while working, the moving guide will move at a high speed in the fixed point direction of the carrier cable due to self- do.

Therefore, there is an inconvenience that the operator has to leave the work place to move the control box moved to the opposite side of the work place to the work place again. When the control box is moved due to the self-weight deflection of the carrier cable, .

In order to solve such a problem, Korean Utility Model Publication No. 1998-0008095 discloses a movement guide installed at a lower portion of a rail of a crane and a hoist so as to be movable by a plurality of wheels, An insulating member which is fixed to one side of the lower surface of the movement guide by a fixing means and through which the carrier cable is connected so that the control box is connected to one end; The spring-loaded spring box is tightened by the nut while the upper end is inserted into the hole of the movement guide, the rod-like stopper is built in the spring, the upper surface thereof is brought into close contact with the lower surface of the rail by the spring, There has been proposed an apparatus for preventing the crane and hoist control box from being pushed up by the control box connected to the bolt loop while the bolt passing through the lower surface of the box is movably engaged.

This is because the control box is moved in line with the movement of the crane and the hoist, and the control box is still connected to the crane and the hoist by wire, And a malfunction of the device itself.

Further, since the conventional control box is formed in a simple square box shape, there is a problem that the operator torns the fingers or generates contusions due to the sharp edges of the box in the long time operation.

In addition, there is no apparatus for instantaneous stopping the driving of assembling robots or welding devices, cranes and hoists controlled by control signals in the event of an emergency, and the power switch of the assembling robots, the welding devices, the cranes and the hoists are individually cut off, There was a problem to be made.
