Technical Field

The invention relates to the technical field of planishers, in particular to a bilateral automatic roll changing method of a planisher.

Background

The automatic roll changing of the temper mill can obviously reduce the time of manual roll changing, and provides important guarantee for the continuous production of a production line.

The currently generally adopted automatic roll changing mode can only be carried out on the transmission side, namely, a new roll is prepared on the transmission side, the roll is pushed in from the transmission side during roll changing, and the middle roll/working roll in the rack is pushed to a roll changing trolley on the operation side. Or the middle roller/working roller in the frame is pulled out to the transmission side, if no cross sliding vehicle exists, the old roller is lifted away by a travelling crane, then the new roller is placed to the transmission side, and then the new roller is pushed into the frame of the leveler. When the roller changing equipment on the transmission side breaks down, the roller changing time is difficult to guarantee.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide a double-side automatic roll changing method of a temper mill.

The technical scheme adopted by the invention for solving the technical problems is as follows: the automatic roll changing method on two sides of the temper mill comprises a temper mill frame, an operation side and a transmission side, wherein the operation side and the transmission side are located on two sides of the temper mill frame, the operation side and the transmission side are respectively provided with a set of clamp trolley and a set of cross sliding trolley, the cross sliding trolley is provided with two roll cages for storing an upper middle roll, a lower middle roll and an upper working roll, the clamp trolley and the cross sliding trolley are electrically connected with an HMI (human machine interface), and the HMI is provided with six sequential control instructions for executing a roll changing command, and specifically comprises the following:

1) the forward control ① drive side pushes in the new roller and the operation side receives the old roller;

2) pulling out the old roller from the transmission side of the sequential control ②;

3) the drive side of the sequential control ③ pushes in a new roller;

4) the operation side of the sequential control ④ pushes in a new roller, and the transmission side receives an old roller;

5) pulling out the old roller from the operation side of the control ⑤;

6) the compliant ⑥ operating side pushes in the new roll.

Specifically, the HMI executes the sequence control command by selecting the sequence control command, executing the sequence control command, starting sequence control, opening the middle roller and/or the working roller locking device, judging whether the tightening device is opened or not, if not, continuing to wait for time-out and giving an alarm, if so, executing the next step, opening the clamp of the operation side and/or the transmission side clamp vehicle, advancing the operation side and/or the transmission side clamp vehicle to the position of the temper mill frame, clamping the clamp of the operation side and/or the transmission side clamp vehicle, pushing the operation side and/or the transmission side clamp vehicle back to the position of the old roller storage and simultaneously pushing the operation side and/or the transmission side clamp vehicle to the position of the temper mill frame, opening the clamp of the operation side and/or the transmission side clamp vehicle and simultaneously locking the middle roller and/or the working roller in the temper mill frame, and respectively returning the clamp vehicles of the operation side and/or the transmission side to the initial position, and finishing sequential control.

Specifically, whether each step of executing the sequence control command by the HMI is completed or not is judged, if not, the HMI continues to wait and carries out overtime alarm, and if so, the HMI carries out the next step.

Specifically, in step 4, the operating side of the sequence control ④ pushes in a new roller, before the transmission side receives an old roller, it needs to be ensured that a roller cage is empty on the transmission side for storing the old roller pulled out from the rack, and the new roller needs to be placed in the roller cage on the operating side in advance.

Specifically, the sequential control ⑤ in the step 5 and the sequential control ⑥ in the step 6 are combined to perform one-side roll change on the operation side of the leveler, and only a manual mode is used for switching the positions of two roll cages by moving the traverse car, so that the equipment safety is ensured.

Specifically, the HMI adapts to different service cycles of the intermediate roller and the working roller, and selects a mode of simultaneously replacing the intermediate roller and the working roller or selects a mode of only replacing the working roller.

The invention has the following beneficial effects:

the automatic roll changing method on the two sides of the temper mill, which is designed by the invention, realizes automatic roll changing on the operation side, so that the roll changing scheme is richer, the roll is convenient for operators to flexibly prepare the roll, the roll is not limited to be prepared only on the transmission side, the capacity of the whole roll changing system for dealing with equipment faults is improved, and the continuous production of a production line is further ensured.
