The frame 100 has the shape of a box. The side of the box in which the conveyor system 200 is located is open. A pair of guides 110 are located in the upper and lower parts of the interior of the frame 100. Both ends of the support 14 are slidably connectable to the guide 110. At this time, when the support 14 moves up and down, it guides the trajectory in which you are going to move. A lifting cylinder 11 of the vertical movement unit 10 is fixed and established in the lower part of the frame 100. The end of a piston rod of the lifting cylinder 11 is connected to the support 14, thus moving the support 14 upwards and downwards. .

In the horizontal movement unit 20, one end of the forward and rearward movement cylinder 21 is fixed in the holder 14. One end of a piston rod 22 of the anterior / rear cylinder 21 is connected to the rotating cylinder 31, thus moving the rotating cylinder 31 vertically. In other words, by connecting the end of the piston rod 22 of the movement cylinder back and forth to one side of a bracket 35, and connecting the other end of the bracket 35 to the rotary cylinder 31, the rotary cylinder 31 is moved horizontally. In addition, between the frame 100 and the vertical movement unit 10, an operational height control unit 50 is established to set the operating height before the operation begins.

The operation of the apparatus for rotating the monitor having the structure described above will be explained below. Figure 6 is a flow diagram illustrating the order of operation of the apparatus for rotating the monitor. First, an operator sets the operating height by adjusting the operational height control unit 50 according to the height of the conveyor belt system 200 or the size of the monitor body 1. When the operator rotates the magician 55 in a clockwise or counterclockwise direction. levorotatory, the screw rod 53 is rotated with respect to the fixed plate 51 without contact. On the other hand, since the operation plate 52 and the screw rod 53 are tightly held, the operation plate 52 moves up or down according to the direction of rotation of the handle 55. At this time, as the The operation plate 52 is fixed in the lifting cylinder 11, the lifting cylinder 11 and other parts connected to the lifting cylinder 11 move simultaneously upwards or downwards as the case may be. In this case, the screw rod 53 is connected to the fixed plate 51 able to rotate without contact, the screw rod 53 can not move by itself. After completing the initial setting operation as described, the conveyor system 200 begins to be operated. The operation performed on the conveyor system 200 will be explained below. When the body of the monitor 1 is located on the platform 220 on the frame 210 of the conveyor belt moves (step 10), it is determined if the body of the monitor 1 which is located on the platform 220 arrives in the operating position through of the detector 230 (step 20). In the event that the body of the monitor 1 arrives in the operating position in step 20, the platform 220 in which the monitor 1 is loaded moves to the next step. Otherwise, by continuously operating the conveyor system 200, the platform 220 on which the monitor 1 is loaded is also continuously moved. When the monitor 1 arrives in the operating position, the signal detected by the detector 230 is input to the monitor. microprocessor 62. The microprocessor reading the input signal transmits each operation control signal to the conveyor drive unit 63 and the drive unit 64 of the cylinder. At this time, the signal input to the drive unit 63 of the conveyor belt stops the operation of the conveyor system 200, and the signal introduced to the drive unit 64 of the cylinder operates the forward / backward movement cylinder 21. By operating the forward / backward movement cylinder 21 (step 30), the piston rod 22 moves forward or forward. backward. After that, it is determined whether the suction pad 41 is tightly in contact with the body of the monitor 1 caused by the movement of the piston rod through the detector 23 which is mounted on the cylinder surface of forward / forward movement. back 21 (step 40). As a result of the determination of step 40, when the suction pad 41 is tightly connected to the body of the monitor 1, the next step is performed. In the event that the suction pad 41 is not tightly connected to the monitor body 1, the forward / backward movement cylinder 21 is operated continuously. The signal detected by the detector 23 is input to the microprocessor 62 and the microprocessor receiving the signal transmits the operation control signal to the valve 43 and the cylinder drive unit 64.

The valve 43 that receives the operation control signal is opened. At this time, when the compressor (not shown) inhales air through the air vent, the body of the monitor 1 is sucked into the suction pad 41, whereby it is clamped (step 50). The cylinder drive unit 64 that receives the operation control signal stops the forward / backward movement cylinder 21, and then operates the lift cylinder 11, thereby raising the support 14 (step 60). After that, it is determined if the body of the monitor 1 is raised to the desired height by means of the detector 13 mounted on the cylinder 11 (step 70). At that time, when the body of the monitor 1 is lifted, the support 14 is guided by means of a pair of the guides 110, and in this way is stably lifted. When the body of the monitor 1 is raised to the desired height in step 70, the next step is performed. In the event that the monitor body 1 is not raised to the desired height, the lift cylinder 11 is operated continuously. At this time, the signal detected by the detector 13 is input to the microprocessor 62, and the microprocessor reading the signal transmits the operation control signal to the cylinder drive unit 64. The cylinder drive unit 64 that receives the signal from The operation control stops the lifting cylinder 11, and rotates the monitor body 1 by operating the rotation cylinder 31 (step 80). After that, it is determined whether the monitor body 1 is properly rotated by means of the detector 33 which is mounted on the rotation cylinder 31 (step 90). When the body of the monitor 1 is rotated at the desired angle in step 90, the next step is performed. In the event that the body of the monitor is not rotated at the desired angle, the rotating cylinder 31 is operated continuously. At this time, the signal detected by the detector 33 is input to the microprocessor 62, and the microprocessor 62 reading the signal transmits the operation control signal to the cylinder drive unit 64, and therefore the operation of the rotation cylinder 31 stops. When the body of the monitor 1 is rotated at a predetermined angle and then stopped, the operator fixes the support using a bolt or other connecting units at the bottom of the body of the monitor 1 (step 100). After that, it is determined whether the operation is complete (step 110). In the event that the operation is not completed, the operation that is not completed is continuously performed. When the operation is contemplated, the switch 65 is turned on and the final operation signal is input to the microprocessor 62. The microprocessor 62 that receives the final operation signal reads the signal and transmits the operation control signal to the cylinder drive unit 64. The cylinder drive unit 64 receiving the operation control signal rotates the monitor body 1 to which the support 2 is connected by operation of the rotation cylinder 31 (step 120). After that, it is determined whether the body of the monitor 1 that is fastened to the suction pad 41 is rotated at the initial angle by the signal detected by the detector 33 (step 130). When the body of monitor 1 is rotated at the desired initial angle of step 130, the next step is performed. In the event that the body of the monitor 1 is not rotated at the desired initial angle, the rotation cylinder 31 is operated continuously. At this time, the signal detected by the detector 33 is input to the microprocessor 62, and the microprocessor 62 reading the signal transmits the operation signal to the cylinder drive unit 64, and therefore the rotation cylinder 31 is stopped. After that, by operating the lift cylinder 11, the support 14 moves downward to the desired position (step 140). It is determined if the body of the monitor 1 is lowered to the desired position by the detector 13 which is mounted on the lift cylinder 11 (step 150). Here, the desired position indicates the position in which the support 2 connected to the body of the monitor 1 is fixed on the upper surface of the platform 220 which is used as a transport element on the conveyor system 200.

When the body of the monitor 1 is lowered to the desired position in step 150, the next step is performed.

In the case where the body of the monitor 1 is not lowered to the desired position, the lifting cylinder 11 is operated continuously. At that time, the signal detected by the detector 13 is input to the microprocessor 62, and the microprocessor 62 reading the signal transmits the operation signals to the cylinder drive unit 64 and the valve 43 that opens to hold the body of the monitor 1. The cylinder drive unit 64 stops the lift cylinder 11, and the valve 43 that receives the closing operation control signal, and therefore the monitor body 1 which is held by the air suction is separated from the the suction pad 41 (step 160). After that, the suction pad 41 moves backward by operating in the forward / backward movement cylinder 21 (step 170), and then it is determined whether the suction pad 41 from which the body of the monitor is separated 1 it is returned to the desired position by the detector 23 mounted on the forward / backward movement cylinder 21 (180). When the suction pad 41 is returned to the desired position in step 180, the next step is performed. In the case where the suction pad 41 is not returned to the desired position, the forward / backward movement cylinder 21 is continuously operated.

Here, the signal detected by the detector 23 is input to the microprocessor 62, and the microprocessor 62 reading the signals transmits the operation control signal to the cylinder drive unit 64. After the cylinder drive unit 64 receiving the The operation control signal stops the forward / backward movement cylinder 21, the cylinder drive unit 64 lowers the support 14 operating the lift cylinder 11 (step 190). After that, it is determined whether the suction pad 41 is returned to the initial position by the detector 13 (step 200). The signal detected by the detector 13 is input to the microprocessor 62 according to the determination of the step 200, and the microprocessor 62 reading the signal transmits the operation signal to the cylinder drive unit 64 and stops the lift cylinder 11. After of that, the microprocessor 62 operates the conveyor system 200 by transmitting the operation control signal to the conveyor belt drive unit 63 and moves the monitor body 1 terminating the mounting operation of the carrier 2 to the next operating procedure ( step 210). The operations described above are carried out repeatedly. As described above, in accordance with the present invention, by providing the apparatus capable of rotating the body of the monitor and the method thereof for the assembly of the support, it is possible to perform the operation without company, thus reducing operating expenses and hours of work and increasing the efficiency of operation.
