Description

[Detailed explanation of the idea] This invention relates to a ringer roll stand.

In continuous annealing, electrolytic tin plating lines, electrolytic galvanizing lines, etc., there are many surface treatment sections using chemical solutions, and a ringer roll is installed in each section for the purpose of preventing liquid carryover, liquid unevenness, etc. .

In the case of a high-speed line, the ringer rolls are used as a ringer roll stand in which two or three sets of ringer rolls are assembled in tandem in order to sufficiently perform the throttling function.

Such a ringer roll stand is usually constructed in a vertical shape, and there have been problems such as difficulty in replacing the roll due to wear of the roll, lengthening of the work time, and safety.

Conventionally, as a method to solve this problem, for example, Ringer
A method has been proposed in which the entire roll stand is replaced with a spare part, but in this method, it is difficult to pull it out to the operation side or the other side unless the steel plate between the opposing ringer rolls is cut and removed. Such work is unfavorable from a safety standpoint, and has drawbacks such as the fact that it takes about 5 hours/set to replace the stand even when done by a skilled worker.

In addition, in order to remove each roll from the removed stand, it is necessary to pull it out horizontally using the porter bar method, or to turn the stand sideways and lift it out one by one using a crane, but this process is also not easy and takes about 5 hours per roll. It takes about 6 hours.

It is also possible to horizontally pull out the roll using the Porter-Baca method while the stand is still installed on the line, but this is not only dangerous, but also requires rolling down and centering adjustment each time. It takes about 6 hours.

In this way, conventionally, there is no definitive method for replacing ringer rolls, and replacing the roll during sheet threading immediately results in production stoppage.From the perspective of improving productivity, there is no need to cut and remove the steel sheet. Additionally, there was a need for a device and method that has good workability and allows rolls to be replaced in a short period of time.

This invention aims to provide a ringer roll stand that can meet this demand, and the stand itself is divided into one stand that supports one of the opposing ringer rolls and the other stand that supports the other roll. The two stands are fastened to each other, and can be unfastened and divided as necessary.

FIG. 1 is a side view of one embodiment of the ringer roll stand according to this invention, and shows an example installed on a processing tank A.

Further, FIG. 2 is a plan view thereof, and FIG. 3 is a front view thereof.

The stand main body 1 is configured so that it can be vertically divided from the middle into one stand 1a and the other stand 1b.

A plurality of ringer rolls 2a (three sets in the figure) are provided in the stand 1a in the vertical direction.

A ringer roll 2b is also provided on the stand 1b.

The ringer rolls 2a and 2b correspond to each other.

These are placed on the ringer roll 2b.
A pressing cylinder 4 is provided for pressing against.

Each ringer roll is also connected to a drive (not shown).

The stands 1a and 1b are fastened together using clamp bolts 5 provided at both ends of the upper surface of the stand, ordinary bolts 6 provided at both ends of the lower part of the stand, and furthermore, bolts connected to the roll axis at both ends of the stands 1a and 1b. This is realized by a presser rod 7 that penetrates almost orthogonally.

Further, the stands 1a and 1b are fixed via bolts 9 at both end portions of each stand via chevron-shaped seats 8 installed on the tank.

This chevron-shaped catch seat 8 is for centering, and if the stand is equipped with a member having a recess that matches the chevron shape of this catch seat 8, it will automatically be placed on this catch seat 8. Centering is completed.

Note that X is a copper band. Next, a method for replacing the roll of this stand will be explained.

First, remove the fastening device on the drive side of the roll 2, that is, the crank bolt 5, normal bolt 6, and presser rod 7 at the end on the stand side, and then remove the bolt 9 to unfasten it from the tank. Pass the steel strip X through the gap and take out the stand main body 1 to the free side.

Next, the stand main body 1 taken out is placed on a replacement table, and on this table, the free side fastening device, that is, the crank bolt 5, normal bolt 6, and presser rod 7 at the other end are removed.

Then, the stand 1a or 1b is moved in parallel to create a gap necessary for exchanging the roll 2.

Moreover, by making the exchange table reversible, each roll 2 can be easily lifted upward by using an overhead crane or the like by rotating the stands 1a and 1b in opposite directions.

Furthermore, an overturning type in which the stands 1a and 1b are overturned in opposite directions is also possible.

Furthermore, this embodiment has the following configuration in addition to the above configuration.

That is, first, as shown in FIG. 2, a rail 20 is provided on the tank A, an external rail 21 is provided continuously to the rail 20 so as to be able to approach and separate from it, and wheels are further provided on the stand 1 so that the rail 20 can be moved on the rail. It is configured so that it can be moved.

A is the driving device side, and B is the free side.

The rail 20 is separated from a rail 20a on which the stand 1a is placed and a rail 20b on which the stand 1b is placed.

This rail 20 can be raised and lowered, and is lowered in a normal state, and the stand 1 is installed on the chevron-shaped seat 8.

Furthermore, as shown in FIGS. 1 and 3, the rail 20 is placed on a lower wedge 30 and an upper wedge 31 that fits and slides thereon, and is raised and lowered by driving a cylinder 32 that drives the upper wedge 31. It is configured to simultaneously move parallel to the left and right.

That is, as the rails 20ay and 20b rise, they are configured to separate from each other and match the external rail 21. When moving the stand 1 onto the external rail 21, the rail 20 is raised and the stands 1a and 1b are moved simultaneously. It is designed so that it can be separated.

FIG. 4 shows a state in which one stand 1b is separated.

After the stand 1 is lifted and separated, the stand moving device 2
2, the stand 1 is moved onto the external rail 21, and the rolls are replaced in the manner described above.

Note that 10 is a wheel provided on the stand 1.

Further, the moving device 22 can have any configuration, but in this embodiment, sprocket wheels 24, 24 are provided at both ends under the external rail 21, and a hook 26 for hooking the stand 1 thereon is provided. equipped chain 25
, and the hook 26 is pulled by the motor 23.

As explained above, according to this invention, the stand can be
Since it is divisible, it is easy to replace the rolls.
The working time is short, which is favorable from a safety standpoint, and there is also no need to cut and remove the copper strip.
