The present invention provides a method of transporting a television and its apparatus, and more particularly, a television which is transported from an automatic supply line, after adsorbing and gripping a portion of the CRT which is easily adsorbed in vacuum, and then transported to a different supply line in a changed position The present invention relates to a transfer method and an apparatus capable of coping with the interruption of power or air supply.

Conventionally, as a means for changing the direction of the conveyed television to an angle suitable for work, a method of turning the desired angle by using the rack and pinion is used.

In this case, structurally requiring a plurality of cylinders, and because the rack and pinion and a bracket for supporting them should be installed, there is a problem that the robot apparatus is complicated and the weight is increased.

In addition, when lifting or moving the television, the cylinder was used to move to another place while holding the side surface of the television.

However, the narrow gripping portion by the working arm of the cylinder results in a relatively weak gripping force.

In order to improve this vulnerability, when the gripping part of the working arm is enlarged, the overall structure has to be enlarged, and the mechanical gripping method itself due to the reciprocating motion of the cylinder is poor in accuracy and lacks reliability.

On the other hand, the conventional apparatus does not have a countermeasure against the disadvantages of the process of gripping and transporting the television, and the air supply to the cylinder is lowered when the power and air supply are interrupted during the transfer operation. There is also a problem that a loss such as detached and damaged TV is generated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a conveying method and apparatus for television that can improve the gripping force under a simple and heavy structure.

Another object of the present invention is to provide a method and apparatus for transporting a television, which can maintain a safe state even in an unexpected situation such as air and power interruption as well as precise operation.

The present invention deforms and loads a television to be conveyed at various angles using a link member interlocked by one cylinder.

The link member for performing the operation has a structure that is operated in the direction set by the appearance operation of the cylinder, for example from the horizontal state to the vertical direction, the suction pad having a mounting function is installed at the end between the operation.

The air supplied to the adsorption pad is removed by the check valve and the solenoid valve for vacuum, and these valves ensure stability by preventing backflow of the air supplied to the adsorption plate when air and power supply are interrupted.

On the other hand, the adsorption portion of the television is relatively flat, the tube is a center of gravity is suitable, it is characterized by setting the operation direction of the link member accordingly.

1 and 2 show the overall outline of the present invention, the support belt 11 is placed on the conveyor belt 10 to which the product is conveyed to the product reached by the lift device 20 The conveyor belt is pulled in and sequentially in order.

The product placed on this support can be a finished or semi-finished product as a television set or monitor set, but is placed on the support such that the surface of the C tube is directed toward the ground.

Adjacent to the conveyor belt 10, a second conveyor belt (10a) for transferring the product to another process is installed, the robot 30 for transferring the product between these belts is installed.

The robot is moved to the X, Y, and Z sides on the frame 40 structure, and has a gripping means capable of gripping a product.

As a holding means, the link member 32 supported by the hinge bracket 34 provided in the board | substrate and operated by the cylinder 31 is provided, and the operation part 33 integrally joined to the link member has a product by air pressure. Adsorption pads 35 for adsorbing are provided.

The link member 32 is operated based on the hinge shaft 32 ′ attached to the hinge bracket 34, and its operating range can be modified at various angles. Likewise, it is preferable to allow the operation 33 to be deformed vertically from the horizontal state.

5 shows a specific embodiment of the adsorption pad 35.

Its overall shape is designed to shape the adsorption surface concave, taking into consideration the carrying weight and safety factor of the product, and guide jaw on the appropriate part of the adsorption surface to increase the sufficient adsorption power and precision during repeated adsorption and holding by vacuum. (35 ') 35 was formed.

6 is for controlling the pneumatic pressure supplied to the cylinder 31 and the suction pad 35, the pneumatic device divided by a dotted line has a plurality of solenoid valves (SV1 ~ SV3) to start and release the vacuum, It is a check valve (CV1, CV2) that keeps residual vacuum continuously when air and power are cut off.

In particular, the solenoid valve SV4 provided in close proximity to the cylinder 31 functions as an intermediate stop valve when air, power, etc. are shut off during the inlet / out operation of the cylinder, thereby preventing it from falling arbitrarily by the weight of the adsorbed product.

Therefore, the present invention as described above, the CRT (B) of the product to be conveyed to the conveyor belt 10 is directed downward to reach the robot 30.

In the upper space of the conveyor belt 50 at which the product reaches and stops, an operation 33 for moving the product waits in a horizontal state. As directed, it provides a condition that can be close to the CRT.

In addition, in order for the operation 31 to be in a horizontal state, the cylinder 31 moves forward and the link member 32 supported by the hinge bracket 34 is rotated at an angle of 90 ° from the hinge axis 32 '. It is possible by raising it.

Attainment and detection of the suction position are made by a separate sensor, whereby the cylinder 31, the link member 32, and the operation 33 which are constituting the robot 30 are raised together with the suction pad 35 at the same time. As a vacuum is applied, the bottom of the product is adsorbed and held.

The robot 30 holding the product is gradually raised on the structure of the frame 40, and then moved horizontally to the upper position of the second conveyor belt 10a, and the plate 10a 'positioned at the lower portion is moved to the lifting height. Stop until you come up.

Subsequently, when the plate and the robot 30 satisfy the set distance, the cylinder 31 moves backward to close the link member 32 and the operation 33 which are fastened to the hinge bracket 32 by the hinge shaft 32 '. ° Angle down.

Therefore, the product held on the suction pad 35 between the operation 33 is placed on the plate 11a with its position changed from the horizontal state to the vertical state, thereby entering the second conveyor belt 10a. Will be.

After adsorbing and holding the product from the conveyor belt 10 as described above, the air or power supplied to the cylinder 31 and the suction pad 35 may be unexpectedly cut off during the process of transferring the product to the second conveyor belt 10a. In this case, the plurality of check valves CV1 and CV2 and the plurality of solenoid valves SV1 to SV4 provided in the pneumatic apparatus are operated to maintain residual vacuum and to prevent safety from falling of the product.

As such, the present invention is capable of safe conveyance with less force when clamping the narrow part of the gripping site by adsorbing and gripping a relatively broad grappling surface due to the characteristics of the braun tube, thereby simplifying the transfer and change of position of the product. Performed by the operation and the device has an economic effect to reduce the production cost.
