Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-line care method and apparatus for removing foreign substances adhering to the surface of a rubber roll used in a process line for metal strips, etc., in the state of use.

[0002]

2. Description of the Related Art In a process line of a metal strip such as a steel strip (which will be described below by way of example of a steel strip), as a transport roll, a metal roll has a high coefficient of friction and a flaw is imparted to the metal strip. A roll having a soft elastic body such as rubber lined on its surface (hereinafter, simply referred to as a rubber roll) is often used so as not to have it.

When foreign matter brought in from the surface of the steel strip or the like adheres to the surface of the transport roll, it is transferred to the surface of the transport roll, causing scratches on the steel strip or accumulating on the surface of the transport roll to reduce the friction coefficient. However, it may cause slipping and meandering of the steel strip, so it is necessary to maintain the roll surface at any time. In the case of a metal roll, an online maintenance device is known in which a grindstone, an abrasive grain belt or the like is pressed against the roll surface for removal. In the case of a rubber roll, it is common to hold a knife-shaped blade close to the roll surface to scrape off foreign matter. As an example, the one described in Japanese Utility Model Laid-Open No. 59-133666 will be described with reference to FIGS.

FIG. 3 is a side view of this roll care device, and FIG. 4 is a plan view thereof. S is a steel strip, D is a foreign substance, 1 is a rubber roll,
51 is a scraper blade, 52 is a roller, 53 is a scraper head, and 54 is a pusher. This roll care device is a roller 52 that rolls along the roll surface, a scraper head 53 and a pusher 54 that are equipped with a scraper blade 51 that extends the cutting edge to a close position facing the roll surface, and a pusher 54 are divided in the roll width direction to form a plurality of groups The pusher 54 holds the scraper head 53 at a constant distance from the surface of the rubber roll 1, so that the foreign matter D adhering to the surface of the rubber roll 1 is scraped off by the rotation of the rubber roll 1 in the direction of the arrow.

Although such a blade-type care device is effective, it is important to maintain the gap between the blade portion and the roll, and adjustment must always be made, and a complicated holding mechanism such as a pusher is required. Therefore, when the space around the rubber roll is narrow, it cannot be attached or adjusted. In addition, a method of pressing a brush of nylon or the like onto the surface of the roll to remove foreign matter has been attempted, but when a rubber roll rotates at a high speed of about 1000 rpm, for example, seizure of the brush occurs due to frictional heat. It is necessary to additionally install a spray device for cooling the brush, and when the space around the rubber roll is narrow, it is difficult to install it.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to realize a method and a device for cleaning a rubber roll which has a simple structure and can be easily installed even in a narrow space.

[0007]

A method for caring for a rubber roll according to the present invention is a caring method for caring for the surface of a rubber roll in a process line of a metal strip, and is a swing made of a pipe material in parallel with a rotation axis of the rubber roll. A shaft is provided, and a linear brush that is parallel to the rocking shaft is attached to the rocking shaft so that its tip is in contact with the surface of the rubber roll. Further, the rocking shaft is a spray header that is substantially linear in the axial direction toward the brush. Is arranged, a cooling water pipe is connected to the swing shaft, and the brush is pressed against the surface of the rubber roll while jetting the cooling water toward the brush.

Further, the rubber roll care device of the present invention is a care device for cleaning the surface of the rubber roll in the process line of the metal strip, and is a pipe material that is swingably provided in parallel with the rotation axis of the rubber roll. And a linear brush attached to the rocking shaft in parallel with the rocking shaft so that its tip is in contact with the surface of the rubber roll, and the rocking shaft is axially directed toward the brush. A spray nozzle arranged substantially linearly, an arm attached to the swing shaft in a direction substantially opposite to the brush,
A counterweight is attached to the tip of the arm, and a cooling water pipe is connected to the swing shaft via a flexible hose.

[0009]

[Operation] According to the present invention, since the swing shaft that presses the brush against the rubber roll is also used as the spray header, a separate device for spraying is not required, and the structure is compact and can be installed in a narrow space. It became easier to install.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view of a roll care device according to this embodiment,
FIG. 2 is a sectional view taken along the line AA, where 1 is a rubber roll,
Reference numeral 2 is a brush, 3 is a swing shaft, 4 is a spray nozzle, 5 is an arm, 6 is a counterweight, 7 is a bearing, and 8 is a flexible hose.

A linear brush 2 having a length substantially corresponding to the roll width of the rubber roll 1 is swingably attached in parallel to the rotation axis of the rubber roll by a swing shaft 3 supported by bearings 7 at both ends. The counterweight 6 having an appropriate weight is attached to the tip end of the arm 5 attached to the swing shaft 3 in a direction substantially opposite to the brush 2, so that the brush 2 is applied to the surface of the rubber roll 1 with an appropriate pressing pressure. Foreign matter D that has been pressed against the surface and has adhered to the surface by the rotation of the roll
Is removed.

The rocking shaft 3 is a hollow pipe material, one end of which is connected to a cooling water pipe (not shown) via a flexible hose 8, and a spray nozzle 4 is formed on the side surface of the rocking shaft 3 in a substantially straight line in the axial direction. Are arranged in a line to form a spray header. Since the direction of the spray nozzle 4 is fixed toward the brush 2 and the positional relationship between the spray nozzle 4 and the brush 2 is constant even if the swing shaft 3 swings and its angle changes, the flexible hose 8 When water is passed through the swing shaft 3 through the cooling water, the cooling water is surely sprayed on the contact surface of the brush 2 with the roll, and the brush 2 can be prevented from overheating.

The roll care device of the present invention was attached to a deflector roll installed in a steel strip process line.
The brush is made of nylon with a wire diameter of 0.75 mm, and the pressing force of the brush by the counterweight is about 5 to 25 kg. By pressing the brush against the line for continuous operation for about 2 hours per week, deposition of deposits was prevented, the coefficient of friction could be maintained at a good value, and seizure of the brush did not occur.

[0014]

According to the present invention, the roll care device can be easily installed even in a narrow space because of its simple structure, the roll surface is always maintained in a good condition, the quality of the steel strip is improved, and the roll life is also improved. It has an excellent effect such as being extended.
