  In the present invention, the upper roller and the lower roller that process the workpiece through the upper roller and the lower roller are separated in the vertical direction, and the upper roller and the lower roller intersect with the feeding direction of the workpiece. The upper and lower rollers are separated and taken out from the position where the workpiece is processed to the take-out position. In particular, the upper roller and the lower roller are moved in a direction intersecting with the feed direction of the object to be processed while being separated in the vertical direction, and the upper roller and the lower roller are moved from the position for processing the object to be processed. It is characterized in that it is guided to the take-out position, and the work of repairing or replacing the upper roller and the lower roller can be easily performed at this take-out position.

  Conventionally, an object to be processed, such as a metal steel plate or a metal strip, is guided between a pair of rollers, and a paint or the like is applied to the surface of the object to be processed through the pair of rollers, or the object is processed using a roller with a brush. The surface of an object is cleaned.

  Here, when the object to be processed is passed between a pair of rollers as described above to apply paint or the like on the surface of the object to be processed or to clean the surface of the object to be processed, the width direction of the object to be processed The roller part that comes into contact with the edge is damaged, or the roller is soiled by deposits that adhere to the workpiece, making it impossible to properly apply paint to the surface of the workpiece, There was a problem that the surface could not be cleaned properly. In addition, when changing the type of paint applied to the surface of the object to be processed or the type of cleaning liquid for cleaning the surface of the object to be processed, if the previous paint or cleaning liquid remains on the surface of the roller, There was a problem that coating failure or cleaning failure occurred due to mixing with the paint or cleaning liquid to be used next.

  For this reason, conventionally, these rollers are separated from each other and taken out from a processing position to be processed, and these rollers are repaired or exchanged.

  Here, in what is shown by patent document 1, in replacing | exchanging a coating roll in the coating apparatus which coats a strip | belt body with a coating roll through a strip | belt body between a backup roll and a coating roll, a coating roll, a pick-up roll , Move the doctor roll etc. away from the strip, and then move the coating unit provided with these rolls in the horizontal direction intersecting the running direction of the strip with the coater carriage to replace the coating roll It has been shown.

After the carriage is removed from the rail, the new upper roller and the lower roller are held by the holding tool. The new carriage thus moved is set on the rail and traveled, and the new upper roller and lower roller are guided to a position for processing the object to be processed.

  However, in this case, since the end of the upper roller and the end of the lower roller are respectively taken out in a state of being gripped by the gripping tool provided on the carriage, only one of the upper roller and the lower roller is repaired. Or the carriage is run with the gripping tool provided at the end of the carriage gripping the end of the upper roller and the end of the lower roller. There are problems such as the cart being tilted and the running of the cart becoming unstable.

  Conventionally, as shown in FIGS. 1 and 2, an upper rail 2 extending in a direction intersecting with the feeding direction of the workpiece W is provided above the upper roller 1 and moved along the upper rail 2. The lower roller holding portion 5a for holding the lower roller 5 rotatably while the upper roller holding portion 1a for holding the upper roller 1 rotatably is held by the lifting device 4 provided on the upper carriage 3 In addition, an apparatus is used that is held up and down by an elevating device 8 provided on a lower carriage 7 that moves on a lower rail 6 that extends in a direction that intersects the feed direction of the workpiece W.

  Here, in such a device, when the upper roller 1 and the lower roller 5 are repaired or replaced, the upper roller holding portion 1a is moved upward by the lifting device 4 as shown in FIG. And the lower roller holding portion 5a is moved downward by the lifting device 8 to separate the upper roller 1 and the lower roller 5 in the vertical direction at the position where the workpiece W is processed. Like that.

  And in this state, as shown in FIG. 4, while moving the upper roller holding | maintenance part 1a hold | maintained at the said upper trolley | bogie 3 along the upper rail 2 in the direction which cross | intersects the feed direction of the to-be-processed object W, Further, the lower roller holding portion 5a held by the lower carriage 7 is moved along the lower rail 6 in a direction crossing the feeding direction of the workpiece W, and the upper roller 1 and the lower roller 5 Are individually guided from a position for processing the workpiece W to an extraction position, and the upper roller 1 and the lower roller 5 are repaired or replaced at the extraction position.

  However, when the upper roller holding portion 1a is guided from the processing position of the workpiece W to the take-out position by the upper carriage 3 that moves along the upper rail 2 as described above, the upper rail 2 is processed. When the upper roller 1 and the lower roller 5 are guided to the take-out position and the upper roller 1 and the lower roller 5 are repaired or replaced, There was a problem that the rail 2 was in the way and the workability was lowered. Further, as described above, the upper roller 1 and the lower roller 5 are individually driven from the position for processing the workpiece W to the take-out position, and thus the upper carriage 3 that moves while holding the upper roller holding portion 1a is driven. It is necessary to separately provide a driving device and a driving device that drives the lower carriage 7 that moves while holding the lower roller holding portion 5a, and there is a problem that the equipment cost is high.
