The present invention is a plate position correcting apparatus installed in a plate processing machine to move the plate to the desired position, by adsorbing the plate into the suction cup to rotate, longitudinal movement and transverse movement to the plate at the correct point It can be positioned at the correct angle.

Plate processing equipment is usually configured by combining a variety of processing devices, such as a feeder for supplying the loaded plate material one by one, a conveyor for transferring the plate to be processed to the next process, and a cutter for cutting the plate.

Generally, sheet processing equipment is a series of automated machines in which each component is controlled by an electric signal of a microcomputer or a computer-embedded control device. The angle and position of the plate may change during the transfer process.

In particular, when precise processing is required, it is necessary to correct the position and angle of the plate for each process, and accordingly, install a guide or stopper for inducing accurate transfer of the plate at a predetermined point of the processing machine. Although the method is used, it can not only hinder the flow of work, but also has a problem that must be replaced every time when the precision falls and the specification of the plate to be processed is changed.

The present invention was devised in view of the above-described problems, and includes a lower frame having a horizontal frame and a driven frame configured to reciprocate at right angles to each other and a suction cup connected thereto and a suction cup for temporarily raising and attaching the plate by suction force; It consists of a rotating motor that rotates the entire frames and a control device that receives video signals from the camera that photographs the plate and controls each motor and pneumatic device accordingly, so that the position of the plate can be automatically corrected. will be.

In the present invention, the rotation and movement of the plate 100, that is, the movement on the plane is made by a motor, and the vertical plate which causes the plate 100 to be raised and adsorbed by applying an air pressure of negative pressure to the plate 100. Movement is performed by external pneumatic application means, such as a suction pump, all of which are controlled by a microcomputer or a computer-controlled control device 330.

Figure 2 is a view showing a state in which the present invention is installed on the conveyor, the plate 100 is being transported by the conveyor instantaneously adsorbed by the adsorption cup 210 to correct the position, the air pressure of the adsorption cup 210 When released, the plate 100 is seated in the desired position.

That is, as shown in Figure 3, by installing the suction cup 210 in a position slightly spaced apart from the upper surface of the conveying plate 100 without a separate lifting means, when the negative pressure air pressure is applied to the suction cup 210 By the suction force, the plate 100 is slightly lifted and adsorbed.

On the other hand, as shown in the enlarged in the ellipse of Fig. 2, the camera 320 is installed on the support frame 310 fixed to the installation target machine, such as a conveyor, and the marks (測 標) indicated on the processing target plate 100 ( 101) or the edge of the plate 100, etc. to measure the angle and position of the plate 100, if the aesthetic appearance 101 is difficult to display, the camera to which the image pickup element outside the visible light area is applied 320 and the hidden index 101 may be used.

The image taken by the gauge 101 and the like is transmitted to the control device 330 connected to the camera 320 and then subjected to image processing, whereby the position error of the plate 100 is read, and the control device 330 ) Corrects the position by driving the motor according to the read position error.

4 and 5 are excerpts of the drive system of the present invention, showing the coupling relationship of each element.
