Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for cleaning the work rolls of a leveler. Can be used for general levelers to correct curls.

[Background technology and its problems]

Generally, a leveler for straightening curls in a coiled material is a device that takes the material taken out from an uncoiler with a pinch roller and straightens it with a number of work rolls arranged alternately. However, dust and chips may adhere to the work roll of the leveler, and if the material is passed through the leveler in this state, the material will be damaged and clouding will occur. Therefore, it is necessary to remove dust and chips adhering to the work roll of the repeller, especially when straightening non-ferrous metals such as aluminum and brass, or materials that are sensitive to scratches such as stainless steel. , chips must be thoroughly removed.

Conventionally, in order to remove dust and chips attached to the work roll of a leveler, a mechanism was installed in which the upper frame of the leveler could be released by a hinge for cleaning the roll, and a mechanism was installed that allowed the upper and lower work rolls to be lifted by increasing the height of the work roll. One with a mechanism that allows you to insert your hand between the rolls to make cleaning easier, one with a mechanism that sprinkles clean oil while threading the material to wash away dirt and chips, or one with a brush roll installed at the entrance of the roll. There are methods that clean the material before threading it. However, the conventional example has the disadvantage that, in addition to the mechanism for straightening the material, a significant mechanism for cleaning the work roll must be added to the leveler, and the conventional example also requires a brush roll to be installed between the rolls. So, what about the dust attached to the work roll?
There is a problem that chips cannot be removed.

[Purpose of the invention]

An object of the present invention is to provide an apparatus that can clean the work rolls of a leveler without adding significant functions to the leveler.

[Means and effects for solving the problems] The present invention provides a slider that is movable in a direction crossing the threading direction of the leveler, a drive source for the slider, and a slider that is movable in the direction that the leveler passes through. The work rolls of the leveler are cleaned by installing a cleaning belt that has at least a flexible surface, is flexible and rigid enough to allow traversal movement as a whole, and has a length that can contact each roll of the leveler. Sometimes, the cleaning belt is inserted in the threading direction of the leveler and moved together with the slider to come into contact with each work roll, thereby removing dust and the like from the work roll surface with the cleaning belt to achieve the above purpose. That is.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1 showing a schematic diagram of the overall configuration, a leveler main body 2 is provided on a base 1, and the leveler main body 2 receives material sent from an uncoiler (not shown) located on the left side of the figure. 3 is straightened, passes through guide roll 4, and goes to the press machine on the right (
(not shown).

The leveler main body 2 has a pair of upper and lower pinch rolls 7 driven by a motor 5 provided in the base 1 via a belt 6.
and a work roll 8 driven by the motor 5 via an interlocking mechanism (not shown). The pair of pinch rolls 7 are provided vertically on the entrance 2A side of the leveler main body 2, and are configured to pinch the material 3 passed through the entrance 2A and send it to the work rolls 8. The work rolls 8 are stacked alternately in two stages, upper and lower, to correct the distortion of the material 3 sent out from the pinch rolls 7, and to straighten the level body 2.
It is designed to send out to the exit 2B side. At this time, the upper roll of each roll 7.8 is movable toward the lower roll, so that an appropriate rolling blade can be applied as necessary.

The guide roll 4 is supported by a guide roll support member 9, and is configured to send the material 3 sent out from the outlet 2B of the level body 2 to the press machine via the loop portion.

A roll cleaning device 10 is provided on the base 1 between the leveler main body 2 and the guide roll 4 so that its longitudinal direction coincides with the width direction of the base 1.

As shown in FIGS. 2 and 3, the roll cleaning device 10 includes a bottom plate 11, a pair of brackets 12 erected at both ends of the bottom plate 11, and horizontally arranged in the vertical direction of the brackets 12. A feed screw shaft 14 is provided between the pair of guide rods 13.
is rotatably provided on the bracket 12 via a bearing 15, and a protruding portion 14A of the feed screw shaft 14 protruding from one bracket 12 is connected via a coupling 16 to a motor 17 as a drive source. . This motor 17 is connected to the bracket 1 via a cylindrical wall 18 and a side wall 19.
It is supported by 2.

A slider 20 is mounted on the guide rod 13 with an impregnated bearing 2.
1, and is disposed at the center of the slider 20 to be movable in the radial direction of the feed screw shaft 14, and
It is secured in the axial direction.

The feed screw shaft 14 is screwed onto the feed screw shaft 14.
As the slider 4 rotates, the slider 20 can move laterally, that is, in a direction intersecting the sheet passing direction of the leveler.

A pair of 'J limit switches 23 are provided near both ends of the bottom plate 11, and when the slider 20 touches the contact 23A of the limit switch 23, the rotation of the motor 17 is reversed and the motor 17 is moved toward one end of the bottom plate 11. Slider 2
0 is adapted to move toward the other end of the bottom plate 11.

The lower pieces of a pair of cleaning belt support fittings 25 that sandwich one end of the cleaning belt 24 are fixed to the upper surface of the slider 20 by bolts 26. At this time, the cleaning belt support fitting 25 can be removed from the slider 20, and when passing the material 3 through the leveler, the cleaning belt support fitting 25 is removed from the slider 20, and a cover (not shown) is removed from the slider 20. ) is covered on the upper surface of the slider 20 and fixed via a bolt 26.

The cleaning belt 24 is long enough to reach all of the work rolls 8 and the pinch rolls 7 in the leveler main body 2, and has an appropriate width and thickness, so that it is inserted in the leveler threading direction. ing.

At this time, the cleaning belt 24 is made of, for example, a cloth used for puff finishing, such as leather wrapped in flannel, to give flexibility to the surface of the cleaning belt 24, and
The cleaning belt 24 as a whole is made to have flexibility and rigidity that allows it to be moved laterally.

Next, the operation of this embodiment will be explained.

After stopping the feeding of the material 3 to the leveler body 2, remove the cover (not shown) covering the top surface of the slider 20 with the bolts 2.
6 and remove it, and move the lower piece of the cleaning belt support fitting 25 holding one end of the cleaning belt 24 onto the slider 20.
is attached via the bolt 26.

Next, the other end of the cleaning belt 24 is connected from the direction of the outlet 2B of the leveler body 2 to the outlet 2B of the leveler body of the work roll 8.
When the cleaning belt 24 is held between the upper and lower rolls on the side and rotated in this state in the opposite direction to the rotation when passing the sheet, the cleaning belt 24 is pulled by the rotational force of the work roll 8 and reaches the entrance of the leveler body 2. It advances in the direction 2A between the work rolls 8 and reaches between the pinch rolls 7. When the motor 17 of the cleaning device 10 is driven with the fil belt 24 inserted between the work roll 8 and the pinch roll 7 in this way, as the feed screw shaft 14 rotates, the slider 2
0 moves laterally, and the cleaning belt 24 also advances between the work rolls 8 while moving laterally. Due to this progression, when the slider 20 reaches one end of the bottom plate 11, one of the limit switches 23 is activated, the motor 17 is reversed, and the slider 20 moves toward the other end of the bottom ville. Furthermore, when the slider 20 reaches the other end of the bottom plate 11, the other one of the limit switches 23 is activated, and the reversed motor 17 rotates in the forward direction, causing the slider 2
0 moves toward one end of the bottom plate 11. Along with such movement of the slider 20, the cleaning belt 24
It advances while moving left and right inside the work roll 8 and the pinch roll 7, thereby cleaning the work roll 8 and the pinch roll 7.

Further, when cleaning of the work roll 8 is completed, driving of the motor 17 of the cleaning device 10 is stopped, and the rotation of the work roll 8 and the pinch roll 7 is reversed from the above-mentioned direction.
That is, the cleaning belt 24 is rotated in the same direction as when passing the material 3, and the cleaning belt 24 is taken out from the work roll 8 and the pinch roll 7, and then the cleaning belt support fitting 25 is moved to the slider 20.
Remove from. Thereafter, the upper surface of the slider 20 is covered with a cover so that the material 3 can be passed through the leveler body 2.

According to this embodiment, the cleaning belt 24 advances while moving left and right inside the work roll 8 and the pinch roll 7, so that the cleaning belt 24 moves inside the work roll 8 and the pinch roll 7 from side to side.

Cleaning can be done thoroughly and easily. In particular, when using a leveler to straighten distortions in materials that are sensitive to scratches, such as aluminum or stainless steel, the work roll 8 can be sufficiently cleaned, so there are almost no scratches or clouds on the straightened material. Since the cleaning device can be easily installed, the leveler can be modified at low cost. Furthermore, since the work roll 8 and the like can be cleaned automatically, no manual labor is required, and maintenance costs can be reduced.

In the above embodiment, the limit switch 23 was used to reversely move the slider 20 left and right, but the present invention does not need to use this. One uses a shaft with an endless spiral groove going in the opposite direction, or one uses a timer or the like to automatically move the motor 17 in the forward and reverse directions.Furthermore, the slider is moved slowly by 2 degrees, and the work roll 8 is moved in the -stroke. If the reed cam shaft is used, the roll cleaning device can be simplified because the limit switch 23 is not used. Further, in the above embodiment, one end of the cleaning belt 24 is supported to clean the work roll 8, etc., but the present invention also supports both ends of the cleaning belt 24 to clean the work roll 8, etc. According to this, the cleaning belt 24 can be reliably moved laterally, so that the work roll 8 and the like can be sufficiently cleaned. Furthermore, in the embodiment described above, the roll cleaning device 10 was provided in the direction of the outlet 2B of the leveler main body 2, but in the present invention,
A roll cleaning device 10 is provided in the direction 2A of the leveler main body 2, and the cleaning belt 2 is installed from this population 2A to the work rolls 8, etc.
In addition, in the embodiment described above, the slider 20 is provided so that the longitudinal direction of the roll cleaning device 10 and the width direction of the base l are aligned, and the slider 20 is inserted through the leveler body 2. Although the slider 20 is moved in the direction perpendicular to the direction, the present invention is not limited to this.
The moving direction of the leveler main body 2 may be made to intersect with the sheet passing direction of the leveler main body 2.Furthermore, in the embodiment described above, the cleaning belt 24 was removed when the work roll 8 etc. were not cleaned, but the present invention Then, the slider 20 may be moved beyond the effective width of the work roll 8 so as not to interfere with the threading of the material 3, and may be placed on standby at a distance from the work roll 8 when cleaning is not performed. .

According to this, the trouble of removing the cleaning belt 24 can be saved. Furthermore, in the above embodiment, the cleaning belt 24 is made of a strip of leather wrapped in flannel, but the present invention is not limited to this. A soft cloth may be wrapped around a core material cut into widths, or it may be pasted or flocked. Any material may be used as long as it can be fed horizontally within the work rolls 8, has a flexible surface, and has the flexibility and rigidity as a whole to be able to be fed horizontally between the rolls.
