The guide rail 120 has a shape that protrudes from one side of the upper end of the rail 110, and the first and second rail wheels 211 of the transport unit 200 are seated to prevent changes in the direction of travel and from the rail 110 during transport. Prevents the transport unit 200 from falling off.

The first sensor unit 130 detects the position of the transport unit 200 and transmits a signal to enable position control of the transport unit 200. This control may be achieved through detection by a sensor and may be achieved by the control unit 250.

The transport unit 200 is a device that transports goods to be transported to a loading location in a configuration in which actual movement is performed along the movement path provided by the rail 110.

Specifically, the transport unit 200 includes a first body 210 that is seated on the rail unit 100, moves in a straight line, and has a perforation at a set position; A second sensor unit 220 disposed at the tip of the first body 210 to detect the position of the first body 210 on the rail unit 100; A battery unit 230 coupled to the first body 210 and divided into two to store power generated by electromagnetic induction; A travel motor 240 that is disposed in the boundary area of the two-part battery unit 230, is coupled to the cross section of the battery unit, maintains its position, and enables movement by receiving power; A control unit 250 that is seated and coupled to the first body 210 to control power distribution and movement operations; It includes a rectifier 260 that maintains the direction of the current generated by electromagnetic induction.

The first body 210 includes a battery unit 230; Travel motor (240); Control unit 250; It is the central configuration in which the raising and lowering rotation unit 300 is combined. That is, each component has a surface area on which to place it. In addition, the first body 210 further includes a perforated coupling hole 210a through which the lifting and lowering rotating part 300 can be inserted and coupled.

The second sensor unit 220 can be installed in the first body 210 and maintained in position. The second sensor unit 220 attempts to control the position of the transport unit 200 through interaction with the first sensor unit 130.

The battery unit 230 is composed of a secondary battery and continuous use is guaranteed by recharging. In other words, the current generated by electromagnetic induction is converted to direct current through the rectifier 260, and then a charging process is performed in which power is supplied to the battery unit 230.

The lifting and lowering rotating unit 300 is a component coupled to the transport unit 200, and is fixed at the retracting position and performs lifting, lowering and rotating movements to more precisely reach the loading position for the goods that have arrived at the linear position through linear motion.

Precise position movement is possible through (130), the second sensor unit 220, and the control unit 250.

Since the location of the place where goods are loaded or transported is determined, the storage area where power is charged is determined in advance. The area where the movement motion is stopped is the starting or ending point of the transfer of the article. Electromagnetic induction is generated in the battery unit 230 and coincides with the area where power is charged. For this purpose, it is a self-evident fact that a power supply device may be buried or placed below the movement path.

As above, stopping and charging of the moving operation are performed simultaneously, and additional lifting and lowering and rotation operations are performed by the lifting and lowering rotation unit 300.

In more detail, the present invention may further include the following configuration.

A second sensor 132 is placed in the rail and guides the starting point of the rail, and determines whether or not the vehicle is dispatched at the starting point depending on whether or not it touches the first rail wheel 211 of the transportation department. A third sensor 133 that determines the imminent arrival of the destination depending on whether the wheel 212 passes through and reduces the speed of the transport unit; and, disposed at the rear end of the rail unit to guide the destination of the rail, and a second rail wheel of the transport unit It may be composed of a fourth sensor 134 that determines whether the destination has been reached depending on whether or not it is grounded.

The first, second, third, and fourth sensors above can be installed on the rail 110.

Specifically, the rail 110 is divided into first and second rails 111 and 112 facing each other, and the first, second, third and fourth sensors 131, 132, 133 and 134 of the sensor unit 130 are It includes those disposed on the first and second rails 111 and 112, respectively.

The battery display unit 231a is formed on the other side of the detection and display unit 231 where the detection sensor unit 231a is disposed, allowing the operator to check whether the battery charging operation is being performed, and this also allows the operator to check whether the battery charging operation is performed. There is an advantage in helping to eliminate etc.

The detection sensor unit 231b can check whether the height is exceeded by detecting the lifting/lowering position and the rise in altitude, that is, the vertical position, as the goods are loaded, and displaying them to the outside. It is obvious that this can visually indicate errors in automated equipment and prevent process interruptions, and can be configured to generate an alarm sound separately.
