[53] Referring to the operation of the present invention in detail as follows.
[54] 11a to 11e is a cross-sectional view for understanding the operation of the product position correction device on the top of the pallet according to the present invention.
[55] First, in the first step of FIG. 11A, the width detecting sensor 201 is operated at the moment when the coiled product 101b is seated on the pallet 102 separated from the coil car 107.
[56] In the second step of FIG. 11B, when the swim bar 203 is down by the swing cylinder 207 and the center bar is detected by the sensor attachment bars 202a and 202b of the width sensor 201, the centering failure coil product 101a is detected. ) Detects the direction to move. In addition, it is detected whether the defect is detected by the width detecting sensor 201 by detecting whether the detected position is moved by the width (size) of the width detecting sensor 201 attached to the sensor attachment bars 202a and 202b.
[57] In the third step of FIG. 11C, if a failure is detected by the width detecting sensor 201, the power transmission traverse 416 performs a lifting operation by the lifting cylinder 406 to ensure the detected defective width.

In addition, when the photo sensors 206a to 206d do not coincide with each other, the secondary operation by sensing the photosensors 206a to 206d is performed by the rotation of the motor 405 in the first operation.
[59] And a hydraulic cylinder having the joint 414 attached to the pallet base 302 by a lifting cylinder 413. The cover of the joint 401a is lifted, so that the hydraulic pressure is the same as that of the secondary motion shaft joints 403a and 403b. The joints 401a and 401b are also engaged. This combined hydraulic The joints 401a and 401b supply power (air) simultaneously with the return to the lifting cylinder 413 home position.
[60] Here, when the primary operation is completed by the power transmission traverse 416, the hydraulic cylinder is operated by the operation of the lifting cylinder 413. Dairy joint with joint 414 of joint 401b attached to pallet base 302 The cover of the joint 401a is reversed. If the conditions of the shaft joints 403a and 403b are correct, the hydraulic The coupling of the joints 401a and 401b is made. And the lifting cylinder 413 is returned to the home position, while the hydraulic The cover of the joint 401a is in close contact with the air supply.

By operation of the screws 308a and 308b, the traverse stages 301a and 301b move to center. When the left and right movement stops of the traverse stages 301a and 301b at the center position detected by the left and right movement width detecting sensors 201, the air pipe 407 is coupled to the shaft joints 401a and 401b. The operation of stopping the center calibration coiled product 101b is stopped by raising the lifting pad stand 303 by the up and down cylinders 304a and 304b by the air supply. Then, the swab bar 203 of the width detecting sensor 201 and the sensor attachment bars 202a and 202b, which has sensed the width, returns to the home position.
[62] In the fifth step of FIG. 11E, when the traverse stages 301a and 301b, which have moved by the width defective guarantee position of the width sensor 201 after the center calibration of the defective centering coil product 101a, return to their original positions, the center calibration is performed. The lifting pad stand 303 which supported the coil-shaped product 101b is down by the up-down cylinders 304a and 304b, and the hydraulic The lifting cylinder 413 of the joint 401b operates. This causes the hydraulic valve to return to the secondary motion iteration of the joint valve (414). At the time when the cover of the joint 401a is reversed, it is returned to the home position of the power transmission traverse 416.
[63] As such, the present invention is to solve the problems of work, such as product conduction, equipment interference, traverse hoisting failure, packaging failure that can occur in the middle of the centering poor coil-type product is moved to the packaging step.
[64] Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.
[65] As described above, the product position calibration device on the top of the pallet according to the present invention, such as product conduction, equipment interference, traverse hoisting failure, packaging failure, etc. that may occur in the middle of the center of the poor centering coil-type product is moved to the packaging step There is an effect that can solve the problem.
[66] In addition, the present invention is a product fall, fall and equipment and the equipment in the vibration landing (shock) due to the characteristics of the rails (104a, 104b) in the process of transported from the production process to the packaging process is seated on the pallet 102 in the center defective state It also has the effect of supplying flawless products by resolving the decrease in the work rate caused by the collision and the defects caused by the manual correction work.
