As shown in Figures 3 and 4, the present invention also discloses a method for fully automatic uncoiling of steel coils, using the above-mentioned automatic steel coil uncoiling device 100, and the uncoiling blade and clamping roller of the automatic steel coil uncoiling device are arranged in the uncoiling position. At the entrance of the pinch roller channel line 200 of the machine, the uncoiling process includes the following steps:

Step 1: The steel coil 300 with the precise head positioning is transported to the uncoiler area by the steel coil transportation trolley, and is put into the uncoiler reel 400, and then the pressing roller 500 is swung in and pressed against the outer ring of the steel coil to prevent the appearance of the coil during the uncoiler process. Loose rolls. Among them, the steel coil head has been positioned at the fixed position of the steel coil trolley in the previous process, and the diameter of the steel coil is measured by means of laser ranging during transportation.

Step 2: Position the initial uncoiling position of the coil head according to the diameter D of the coil. When the steel coil head is being rolled up, the steel coil head is in the direction of about 4:30, and it is inconvenient to unwind at this time. In this way, before unwinding, the tape head needs to be adjusted to the unwinding position. Specifically: when the outer diameter of the steel coil is greater than 1350mm, the reel of the uncoiler is reversed (that is, the clockwise direction in the figure) 180°, so that the lead head turns clockwise from the position of about 4:30 when the coil is rolled up to about 11:30. position, that is, the initial unwinding position of the tape head. When the outer diameter of the steel coil is less than or equal to 1350mm, the reel of the uncoiler needs to be reversed by 200° to reach the initial position of the uncoiler.

The uncoiling initial position of the steel coil head is located below the position of the deep bending roller 600, and the deep bending roller 600 remains at its original position throughout the uncoiling process and does not participate in the uncoiling.

Step 3: Start the unwinding. In the initial state, the blade swinging oil cylinder 6 drives the unwinding blade to rotate 90° counterclockwise, and then the support frame drives the oil cylinder 8 to drive the swing support frame 10 to swing in the direction of the steel coil, that is, the unwinding assembly and the clamping assembly follow the direction of the coil. Swing in, so that the tip of the unwinding blade faces the lead; the uncoiler drum rotates forward (that is, clockwise as shown in the figure), so that the lead is pressed against the upper unwinding blade, and the unwinding blade and the clamping roller The gap passes through and extends forward for a certain distance, and the uncoiler drum stops rotating.

In step 3, the angle of rotation of the uncoiler drum from start to stop is n, n=136000/D, where D is the diameter of the steel coil. In the actual production process, it is set according to the actual situation. For example, when D=2000mm, then n=68°; when D=1500mm, then n=91°.

Step 4: The support frame drives the cylinder 8 to retract the piston rod, so that the swing support frame 10 swings back to its original position. Then the blade swinging cylinder 6 drives the uncoiling blade to rotate 90° clockwise, and after raising the lead, the clamping lifting cylinder 9 drives the clamping roller 2 to press down and press against the strip; then the blade lifting cylinder 7 and clamping The lifting cylinders 9 act synchronously to drive the uncoiling blade and the clamping roller to rise as a whole.

Step 5: The uncoiler starts to rotate forward again, so that the tape head moves to the entrance of the pinch roller channel line and enters the pinch roller channel, the pinch roller is clamped, the uncoiler assembly is reset, the clamping assembly is reset, and the automatic uncoiler is completed.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
