Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a roll care device, and in particular to a structure for a roll care device installed in a processing liquid tank such as a continuous plating line.
This invention relates to the structure of a roll care device for correcting sludge and surface scratches on the surface of a roll.

Conductor rolls used in processing lines such as strip plating lines are subject to sludge adhering to their surfaces due to corrosive fumes generated from plating solutions, or surface scratches may occur due to various factors. Such stains on the roll surface must be periodically corrected, and therefore roll maintenance work is performed.

A device for this roll care has long been desired, but there is a problem in that the equipment corrodes early due to corrosive fumes generated from plating solutions, etc., and conventional technology has been unable to automatically perform roll care. No suitable equipment was ever proposed.

However, in conventional roll care, as shown in Fig. 1, the polishing paver 2 must be wrapped around the tip of a wooden stick 1, and the work must be done by twisting the paver, which is difficult to do in rough terrain. The present invention, which eliminates much manual work, was developed in view of the problems of conventional roll care work, and it automatically removes conductor rolls installed in plating liquid tanks. ...It is an object of the present invention to provide a roll care device that can be manually taken care of.

The present invention achieves the above object by providing a main body that can reciprocate in a direction perpendicular to the line above the surface of the processing liquid, and attaching a polisher roll that can move into and out of contact with a conductor roll to the main body.

That is, according to the present invention, (i) In the roll care device fH that performs surface care of the conductor roll installed in the processing liquid tank of the IJ tube continuous processing line, A reciprocating main body is provided, and the main body supports a polisher roll parallel to the conductor roll, and the polisher roll is placed in a cleaning position in which it contacts the conductor roll and in a retracted position in which it separates from the conductor roll. The driving press is provided with a driving means, and the Bolinyer roll is pivotally supported via a one-way clutch that does not rotate along with the frictional force between the Bolinyer roll and the concrete lid roll;
Further, there is provided a 0-9 care device which is mounted so that it can be driven by a drive means in a rotatable direction by a predetermined angle.

2 to 8 are diagrams showing one embodiment of the roll care device according to the present invention.The present invention will be specifically explained below with reference to these drawings.

FIG. 2 is a diagram illustrating a part of a plating tank in a continuous strip processing line, in which a strip 3, which is a steel plate and other materials to be processed, is connected to a conductor roll 5 installed in a processing liquid tank (plating tank) 4. passing between the backup roll 6,
In the illustrated example, sheet passing roll devices each consisting of a pair of these rolls are installed at a plurality of locations at predetermined intervals. The processing liquid (plating liquid) 7 is stored up to the surface of the strip 3. The conductor roll 5 is cleaned by pressing a polisher roll 8 against it, such as removing surface deposits and correcting surface scratches.

In Figures 3 and 4, plating tank (processing liquid tank) 4
Add the plating solution (processing solution) to the frame 9 installed in one row.
A main body 10 is provided which reciprocates within a predetermined range above the liquid level in a direction perpendicular to the line, and a polisher roll 8 is supported on the main body.

The main body 10 is slidably supported at both ends by slide bearings 11 provided in the frame 9, and is supported within a predetermined range in a direction perpendicular to the line by a sliding cylinder 12 connected between the main body and the frame 9. Two support arms 1.3.13 are fixed to the main body 10, and a bearing 14.13 is provided at the tip of each support arm.
A rotary member 15 that crosses above the processing liquid tank is rotatably supported by 14 .

A pressing drive means 16 consisting of a reciprocating hydraulic cylinder or the like is attached to the main body 10, and the tip of the piston rod is connected to the rotary portion 15. Therefore, the pressing operation can rotate the rotating member 15 by actuating the driving means 1G.

Rotating arms 17A, 17 are provided at both ends of the rotating member 15.
B is fixed, and the shaft of the Bolin Yar roll 8 is pivotally supported at the tips of these rotary arms.1. The polisher roll 8 is arranged parallel to the conductor-o-ib 5,
One rotary arm 17A is pivotally supported via a bearing 18, while the other rotary arm 17B is pivotally supported via a one-way clutch 19 such as a cam clutch.

When the polisher roll 8 is pressed against the rotating conductor roll 5, the one-way clutch 19 does not allow rotation in the direction associated with the frictional force between the polisher roll 8 and the conductor roll, but rotates it in the opposite direction. has a structure that allows it to rotate freely.

A driving means (such as a hydraulic cylinder) 20 is connected between the rotating member 15 and the shaft of the polisher roll 8 for driving and rotating the polisher roll by a predetermined angle in a rotatable direction.

In addition, 1. The rotating member 1'5 is shown in FIGS. 3 and 8.
As shown in the figure, in the above-mentioned drive, 1) when the polisher roll 8 is driven by the drive means 20, a brake device 21 is provided to provide resistance to the rotation of the polisher roll and to ensure its rotational position is accurate. As shown in FIG. 8, this brake device consists of a lug 22 fixed to a rotating member 5, a leaf spring 23 attached to the lug, and a shaft ( In the illustrated example, there is a brake shoe 25 that slides on the outer periphery of a large diameter portion 24) provided on the shaft, and a push bolt 26 that adjusts the braking force by changing the spring force of the leaf spring 23.
It consists of

As shown in FIGS. 5 to 7, the poly/key roll 8 has a segment structure having a plurality of (four in the illustrated example) segments 27.

Each segment has 27 bosses 28 fixed to the roll shaft.
On the other hand, it is removably fixed by a fastener 29 such as a bolt.

Each segment 27 is composed of a segment main body 30 forming a partially arcuate surface, a soft layer 31 of a rubber-like elastic material bonded to the arcuate surface, and a boring paper 32 attached to the surface of the soft layer.

A polishing vane 32 is applied to the end of each segment as shown in FIG. 7, and replaced with a bolt 33. IJ Noh i/i: ,! It is boarded up.

In addition, in the 31st roll 1, a back roll 6 is provided below the conductor roll 5, and the strip 3 is transferred between these rolls by 1 roll. A plating solution (processing solution) 7 is stored in the plating tank (processing solution 4+"f) 4 up to one side of the strip 3.

Fume shielding plates 34 are provided on both sides of the treatment liquid tank 4 at positions 1 and 1 indicated by the two-dot chain line in FIG. Next, the operation when cleaning the rI-ru will be explained.

For pressing, the rotating member 15 is rotated in the direction of the arrow in FIG. 3 by operating the driving means (hydraulic cylinder) 16.
The polisher roll 8, which is normally in the upwardly retracted position 1, is driven to the cleaning position shown in FIGS. 3 and 4 and pressed against the conductor roll 5. The polisher roll 5 is a one-way clutch (such as a cam clutch) 1 that rotates in only one direction.
9, so the rotating conductor
It does not rotate even when pressed against the roll. As a result, slippage occurs between the polisher roll 8 and the conductor roll.
A polishing paper 32 takes care of the conductor roll surface.

At the same time, the sliding cylinder 12 moves the polishing roll 8 together with the main body 10 in the axial direction (in the direction of arrow B in FIG. 3), thereby effectively performing polishing while preventing uneven contact.

After the boring (care) of the conductor roll 5 is completed, the pressing is performed by the driving means 16, and the rotating member 5 and the rotary arms A 17A, 17B are rotated upward to move the boring roll 8 to the retracted position.

At the same time, the operation of the sliding cylinder 12 is also stopped.

If the polishing paper 32 is repeatedly cleaned, the polishing paper 32 becomes clogged and the abrasive grains come off, which deteriorates the polishing effect.
The polisher roll 8 is driven to rotate by a predetermined angle, and a new surface of the polishing vane 32 is automatically sent out. In this way, it is possible to omit replacing the paper every time it is cleaned.

The polygon vane, which is a consumable item, can be easily replaced by simply attaching and detaching the bolts 33 for each segment 27. This paper replacement may be performed, for example, at intervals of about three weeks.

According to the embodiment described above, the surface of the contactor roll installed in the treatment liquid tank of the continuous treatment line for IJ tubes can be automatically and easily cleaned.

In addition, mechanical parts that are susceptible to corrosive fumes, such as the caustic part and sliding parts of the care device, can be removed from above the processing liquid tank, which is effective for corrosion resistance. With this arrangement, a roll care device with even better corrosion resistance and excellent sludge adhesion prevention effect can be obtained.

In addition, by applying an axial sliding motion to the polyger roll 8, a good roll surface without uneven contact can be achieved, and by driving and rotating the polyger roll 8, the poly song effect can be maintained at all times. moreover,
The polysong paper 32 can also be replaced very easily.

As is clear from the above description, the present invention provides a roll care device that can automatically and effectively care for the surface of a conductor roll in a processing liquid tank.
