An ultrasonic sensor S8 for detecting the diameter is installed. Of course, all the sensors, encoders and solenoid valves described above are connected to a central processing unit (not shown). It describes the operation and effect of the present invention with the above configuration.

When the display label automatic inserter 1 of the present invention as shown in FIGS. 1 and 2 is operated, first, the adsorption rubber 33 is moved by the cylinder C1 of the label adsorption unit 30 to the label box ( 32) When the display label 31 is detected by the infrared sensor S3 of the adsorption rubber 33 and descends to the upper side, the operation of the cylinder C1 is stopped and at the same time the solenoid valve V1. Is operated to form a vacuum on the adsorption rubber 33 side, whereby the display label 31 is adsorbed on the adsorption rubber 33. When the display label 31 has completed the adsorption, the cylinder C1 is operated to ascend to raise the adsorption rubber 33 (of course, when the adsorption rubber 33 is raised, the adsorption holding of the display label 31 is applied to the sensor S3. Is detected by the abnormal operation, and the display label 31 is removed from the adsorption rubber 33 by the abnormal operation, the buzzer (not shown) is sounded and the adsorption maintenance of the display label 31 is abnormal. When the ascending of the cylinder C1 is completed, the motor M1 is operated to rotate the cylinder C1 by 180 °, and the control is performed by the proximity sensor S4.

When the completion of rotation of the cylinder C1 is detected by the proximity sensor S4, the rotation of the motor M1 is stopped and at the same time, the label inserting unit 50 starts to operate. That is, signals from each encoder (not shown) for position calculation of the x, y, and z axes are calculated by the central controller (not shown) to confirm the position of the clamp 85, and after the position confirmation, the x axis, y Each of the motors M5, M4 and M3 for the movement of the axis and the z-axis is operated to move the clamp 85 to the display label 31 which is sucked by the suction rubber 33 and rotates.

In this way, the display label 31 is fixed between the upper and lower clamps 85a and 85b. At this time, the solenoid valve V1 'operates to form a vacuum, so that the vacuum state is released and thus the display label 31 is separated from the adsorption rubber 33, and the adsorption rubber 33 is a motor. Operation of (M1) (M2) moves to the initial state and waits for the next work. Of course, the clamp 85 moves to the initial position set by the operation of the motors M3, M4, M5 and stands by.

On the other hand, when the rear end of the preceding steel plate 5 moves to the welding machine 10 side, the movement is stopped and welding is started in the welding machine 10, at which time the connection of the steel sheets 5, 5 'by the proximity switch S1. The welding start signal for the transmission is transmitted to the central control unit (not shown), and at the same time the diameter of the winding coil 90 is measured by the ultrasonic sensor S8 and transmitted to the central control unit (not shown), and the clamp 85 is The coil 90 is moved close to the winding part P. FIG. Of course, in this case, the coil stage detecting sensor S7 attached to the clamp 85 itself detects the coil stage and transmits it to the central controller, and adjusts the position of the clamp 85 at the central controller according to the signal. 31) is placed at an appropriate position between the lower side of the steel sheet 5 to be wound and the coil 90 wound to be in the state just before insertion. When the welding operation is completed and the steel sheet 5 starts to move, the signal is transmitted to the central control unit, and the position of the weld portion W is continuously detected by an encoder (not shown) for measuring the moving distance of the steel sheet 5. When the welding portion W reaches the label insertion point (of course, this position is the position when the distance measured by the encoder reaches a preset set value), the central controller operates the cylinder C2 to display the label. (31) is inserted.

When the insertion of the display label 31 is completed, the clamp 85 is moved to the initial position to wait for the next work.

As described above, according to the present invention, by inserting the display label at the correct position by automating the entire process from welding of the steel sheet to inserting the display label, it improves the reliability of the work and eliminates the risk of safety accidents caused by manual work. It is an excellent design in practical use.
