[0105] Working principle and usage:

[0106] The first step is to install:

[0107] The utility model is installed to one end of the discharge port of the roller processing equipment, and the fixing switch is pressed. The PLC controller outputs a signal to the push rod motor 105, and the push rod motor 105 is started, and the fixation of the utility model is achieved by moving the stop block downward.

[0108] The vehicle is partially transferred to the adjustment box 303, and the fixed switch is long pressed, and the PLC controller outputs signals to the push rod motor 5 304, the push rod motor 6 306, and the electromagnet 2.

[0109] The push rod motor 6 306 drives the limit column to move upward, and the electromagnet 2 is started to fix the vehicle part.

[0110] The push rod motor 5 304 is started with a time delay to move the adjustment block 305 upward to the top of the "U"-shaped hollow container.

[0111] By pressing the switch, the PLC controller outputs a signal to the screw stepper motor, and the screw stepper motor drives the movable carrier plate 207 to move in an orderly manner, thereby realizing the switching of the receiving box structure 209, the positioning rod 210, and the three-claw motor 211.

[0112] Perform a no-load test.

[0113] Second step, use:

[0114] After pressing the loading switch, when the roller (or the semi-finished roller column in its production) reaches above the electric roller 201, the distance sensor module 1 outputs a signal to the PLC controller, and the PLC controller outputs the electric roller 201, the electric roller 2 205, the push rod motor 2 204, the electric roller 3 203, the push rod motor 4 202, the electric lifting device 302, and the electric telescopic rod 212.

[0115] The electric lifting device 302 drives the vehicle to partially move upward until the adjustment block 305 is located on one side of the distance sensor module 2.

[0116] The electric roller shaft 1 201 is started, the push rod motor 2 204, the electric roller shaft 3 203, and the push rod motor 4 202 are delayed started, the push rod motor 4 202 drives the electric roller shaft 3 203 to approach the roller shaft to limit the horizontal direction, and the push rod motor 2 204 drives the electric roller shaft 2 205 to move downward to complete the correction of the roller shaft position.

[0117] The electric roller shaft 1 201, the electric roller shaft 205, and the electric roller shaft 3 203 are started. The electric telescopic rod 212 drives the three-claw motor 211 to move, and the three-claw motor 211 clamps one end of the roller shaft in order. The electric lifting device 302 moves up a distance, and the three-claw motor 211 resets, and then the electric lifting device 302 moves down a distance.

[0118] The servo motor 301 is started with a delay, and the servo motor 301 drives the carrier to move a unit distance, so as to facilitate the subsequent storage of the roller.

[0119] When one layer of adjustment block 305 is fully loaded, the photoelectric counting sensor module outputs a signal to the PLC controller, and the PLC controller controls the push rod motor 5 304 to drive the adjustment block 305 to reset.

[0120] When the roller reaches the third position of the distance sensor module, the PLC controller outputs a signal to the push rod motor 7 307, and the push rod motor 7 307 drives the correction plates 308 to move closer to each other to trim the positions of the two ends of the roller.

[0121] Step 3: Uninstall:

[0122] When the unloading switch is pressed, the PLC controller sends a signal to push rod motor five 304, push rod motor six 306, electromagnet two, electric lifting device 302, and servo motor 301.

[0123] The electromagnet 2 is closed, and the push rod motor 6 306 drives the limit column to move downward. The electric lifting device 302 is reset. The servo motor 301 drives the movable carrier plate 2 to reset, which is convenient for the staff to unload.
