Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments to be described below are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. The present invention is not limited to the embodiments described below, but may be embodied in other forms. In the drawings, the width, length, thickness, etc. of components are exaggerated for the sake of convenience. Like reference numerals designate like elements throughout the specification.

Conventional plate-type steer angle control system is designed to control the product transferred by the roller table in accordance with the ordering code received from the Supervisory Control Computer (SCC), which is informed about the product cut at the D / A fixed type of embossing method is used in which the embossing operation is controlled within 30 mm from the top of the upper surface and within 200 mm from the side cutting portion of the work side.

In recent years, however, customers have been having difficulty in identifying bends in the process of bending after cutting in the case of receiving products by applying the above-mentioned bending method to wind turbines and freight cars, We are asking to be able to confirm by steer in stable position in accordance with the product. However, due to the current facility constraints, customers are not satisfied with their needs. As a result, there are restrictions on customer complaints and orders.

The tracking control unit 40 operates the roller table 60 to transfer the product S to the product 50 in order to transfer the product S placed on the roller table 60 to the picker 50 ).

The tracking control unit 40 calculates the position of the product S using the movement distance of the roller table 60 detected through the position detector 70 (104).

The tracking control unit 40 compares the calculated product position with the target position according to the stored target position information, and determines whether the calculated target product position is the target position according to the stored target position information (106).

If the calculated product position is the steering angle position according to the stored steering angle position information, the tracking control unit 40 stops the roller table 60 because the product S has reached the steering angle position 108). At this time, the conveyance speed of the roller table 60 can be reduced before the product S reaches the target position.

The tracking control unit 40 stops the roller table 60 and guides the product S to the product S through the touch sensor 50 (110).

On the other hand, if it is determined that the product position calculated according to the operation mode 106 is not the steering angle position according to the stored steering angle position information, it is determined whether the product S is sensed by the first position detection sensor 81 (112).

If the product S is sensed by the first position detection sensor 81 as a result of the determination in the operation mode 112, the tracking control unit 40 determines whether the product S is sensed by the second position detection sensor 82 (114).

If the product S is not detected by the second position detection sensor 82 as a result of the determination in the operation mode 114, the tracking control unit 40 determines that the product S reaches only the position where the first position detection sensor 81 is installed (For example, an error with respect to the position of the product S estimated by only the position detector 60) of the product S that may have occurred during the transfer, to the position of the first position detecting sensor 81 To correct the position of the product (S). Since the mounting position of the position detector 70, the mounting position of the rudder 50, the mounting position of the first position detecting sensor 81 and the product length are stored in advance, the product S is detected by the first position detecting sensor 81 The position of the product S at the detected point can be accurately corrected.

On the other hand, if the product S is detected by the second position detection sensor 82 as a result of the determination in the operation mode 114, the product S has reached the position where the second position detection sensor 82 is installed, And corrects the position of the product S by applying the position error of the product S having the second position detecting sensor 82. [ Since the mounting position of the position detector 70, the mounting position of the rudder 50, the mounting position of the second position detecting sensor 82 and the product length are previously stored, the product S is detected by the second position detecting sensor 82 The position of the product S at the detected point can be accurately corrected.

If the product S is not detected by the first position detection sensor 81 as a result of the determination in the operation mode 112, the tracking control unit 40 determines that the product S is still positioned at the position where the first position detection sensor 81 is installed It is moved to the operation mode 102 to perform the following operation mode.

As described above, the embodiment of the present invention is capable of a variable steering angle that can deviate from a fixed type steering angle that is applied only to a specific portion of the top surface of the product S, and can steer various positions requested by the customer.

In the embodiment of the present invention, in the process of transferring a product to a different device using a roller table by receiving the position of the upper surface of the product requested by the customer in the SCC, The position error can be improved by zeroing the position error generated in the transfer process by providing the position detection sensor for detecting the position according to the product width and length. As a result, it is possible to expand new orders for heavy plates by satisfying customer requirements by positioning the accurate steering position required by the customer for the incoming product through the product position tracking control at the bottom of each other.
