Of course, the above-described material transfer robot 2 and all the robots described later are apparatuses for transferring and supplying metal materials or molded articles, and are industrial robots configured by multiple axes and operated by the control of the control unit 8. The technology is already widely used for transferring and supplying materials in the fields of electronics and machinery, and a detailed description thereof will be omitted.

The positioner 3 is composed of a plurality of units, and is disposed between the material transfer robots 2 so that each material transferred by the material transfer robot 2 is seated. That is, the positioner 3 is installed in the drive region of the material transfer robot 2 so that the material transfer can be performed by the material transfer robot 2 and is supported at the upper end of the vertical leg so as to be supported by a number of vertical legs. The provided table top plate is formed so as to be inclined downward from the outside to the inside. The inclination angle of the positioner 3 is preferably about 10 to 45 degrees.

The main role of the positioner 3 is that a robot arranged and fixed on one side of the positioner 3 adsorbs and transfers the material so that the material can be supplied to a fixed position between the upper and lower molds of the press 5 by the robot. This is to place the material at a fixed position so as to fit the driving area of the robot.

More specifically, if the material loaded on the destacker 1 is transferred and fixed on the upper part of the positioner 3 by the material transfer robot 2, the material moves along the inclined surface of the positioner 3 at the corner of the positioner 3. The material supply robot 4 can supply the material of the positioner 3 to the fixed position of the press 5.

The material supply robot 4 includes two robots spaced apart from each other behind the material transfer robot 2 as one set, and adsorbs the material that is seated on the positioner 3 while crossing each other. It plays a role of supplying to the press 5.

Compared to the existing production line, the material supply robot 2, the material supply robot 4, the plurality of destackers 1, and the positioner 3 configured as described above are configured with two material supply lines. More products can be produced.

A large number of presses 5 are sequentially arranged behind the material supply robot 4, and a material is supplied from the material supply robot 4 to press and mold a mold.

In the present invention, all four presses 5 are arranged, but can be additionally installed depending on the type of automobile molded product. In addition, the press 5 is controlled by the main control unit 8, and each press 5 is provided with a separate manual control unit, so that individual control is possible.

That is, the molded product supply robot 6 is arranged so as to correspond to the press 5 and the space provided between the presses 5, and the molded product molded by the press 5 in the previous process is used as the press 5 in the subsequent process. Can be supplied continuously.

The product carry-out robot 7 is composed of a pair of two robots spaced apart from each other. Of the press 5, the product is placed behind the press 5 located at the rearmost position and finished forming while crossing each other. It plays the role which carries out to the outside. Further, it is preferable that a conveyor 9 is installed between the product carry-out robots 7 so as to guide and transfer the finished product.

The controller 8 controls operations of the material transfer robot 2, material supply robot 4, press 5, molded product supply robot 6, and product carry-out robot 7. The control unit 8 is provided with a separate control room at the forefront of the system, and is installed in the control room 8 so that other people outside the operator restrict access.

Hereinafter, a molding process of a molded product by an automatic press molded product manufacturing system using a double robot line for a tandem press line according to the present invention will be described as follows.

First, the material transfer robot 2 in which two sets form a set transfers the material loaded on the destacker 1 to the positioner 3.

The material transferred to the positioner 3 is supplied to a press 5 positioned alternately at the foremost position by a material supply robot 4 in which two units form one set.

When the material supplied to the press 5 is formed into a certain form, the two units are supplied to the press 5 in the next step by the molded product supply robot 6 that forms a set. At this time, the plurality of presses 5 can be composed of 2 or more N (N is a natural number), and the number of presses 5 is further required as the number of forming steps by the press increases.

Here, one robot picks up the product with the press in the previous process, transfers it to the press in the next process, and loads it on the press in the next process. The robot loads the molded product on the press of the next process, moves to the press of the previous process at the press of the next process without the molded product, and sucks the molded product with the press of the previous process. Therefore, the transfer time can be reduced epoch-making by transferring the molded product formed by the press to the next press while the two robots forming one set move in opposite directions. .

Depending on the shape of the molded product, the product formed through various press processes and finally passing through the press 5 located at the rearmost position is guided to the conveyor 9 by the transfer of the product carry-out robot 7 and carried out.
