Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a calender device, and more particularly to a calender device for polishing and repairing scratches generated on the surface of a calendar roller.

(Prior Art) In general, a calendar roller in a calendar device is formed by compressing paper to form a calendar roller, or at least a surface portion of the calendar roller is formed of a synthetic resin in order to enhance the glossing efficiency. If solid lumps or the like are attached to the fabric to be processed or if the fabric is supplied to the calender calendar roller in a broken state, dents or scratches can be made on the surface of the calendar roller due to the solid lumps or folding. Will end up.

If the surface of the calendar roller has dents and scratches, the scratches and streaks will occur on the fabric to be processed.If the scratches are small, rotate the calendar roller while holding it in your hand. Apply the sandpaper you have held to the surface of the calendar roller and level it out.If the scratches are large, remove the calendar roller from the calendar device,
The surface is ground with a grinding machine such as a lathe.

(Problems to be solved by the invention) In the polishing of the calendar roller by the conventional method, for example, when the scratched portion is partially leveled with sandpaper,
It is extremely difficult to even out the work evenly, and requires a skilled worker's experience and experience.

Further, there is a problem that the feeling and experience of the repair work are slightly different depending on each worker, and the scratches cannot be repaired uniformly, resulting in unevenness in the quality of the cloth to be calendered.

In addition, since the correction work is almost manually performed, it takes time and labor, and not only the work efficiency is extremely poor, but also the worker performs the polishing work while rotating the calendar roller so that the worker does not need to change the calendar roller. There is also a problem that there is a high risk that an accident will be involved.

Furthermore, when polishing the surface with a lathe or other polishing device, the calender device must be stopped for a long time before the calender device is removed from the calender device and the calender roller that has been polished is reassembled into the calender device. As a result, the operating efficiency is significantly reduced, and the cost required for the calendar process is also high.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a calendar device equipped with a device that can safely and easily polish a calendar roller in a short time without relying on skill or feeling. The purpose is.

(Means for Solving the Problem) In order to achieve the above object, a calender device according to the present invention is a calender device including a heating roller and a calendar roller that abuts against the heating roller while holding a cloth therebetween. Further, the polishing member for polishing the surface of the calendar roller is formed by the attitude switching means so as to be switchable between a polishing attitude in which it contacts the surface of the calendar roller and a standby attitude in which it is separated from the surface of the calendar roller, and the base end portion is the rotation driving means. The polishing belt is wound so that the tip is located above the calendar roller, and the polishing belt is configured to be rotatable in the rotation direction of the calendar roller or in the opposite direction to form the polishing member. It is characterized in that the polishing device is constituted by providing a moving means for moving the polishing member over substantially the entire width of the surface of the calendar roller.

(Operation) First, when the calender device is in operation, the cloth is calendered in a standby state in which the polishing member is separated from the surface of the calendar roller.

Next, if a solid mass attached to the fabric to be calendered or a dent on the surface of the calendar roller due to folding of the fabric occurs, the polishing belt is rotated by the rotation driving means in the rotation direction of the calendar roller or in the opposite direction. The polishing member is brought into contact with the surface of the calendar roller in a polishing posture while being rotated. After that, when the polishing member is moved by the moving means over the entire width of the calendar roller, the scratches on the surface of the calendar roller are removed by the polishing member, and the surface is beautifully restored.
