Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roller polishing device for polishing rollers of a roller conveyance device that conveys, for example, rolled steel material.

(Prior Art and Problems to be Solved by the Invention) A conveying device for conveying the steel material is installed before and after the rolling device, and this conveying device usually has a plurality of feed rollers on the top surface of the table. Those arranged side by side at appropriate intervals are used.

Scratches, etc. occur on the surface of the feed roller of such a conveying device over time, and if a relatively soft steel material is conveyed with such scratches, for example, immediately after rolling, the surface of the roller may be damaged. A problem arises in that the scratches are transferred. Furthermore, even if foreign matter such as dust adheres to the surface of the feed roller, this foreign matter may be transferred to the surface of the steel material. Therefore, it is necessary to polish the surface of the roller at an appropriate time to remove scratches and foreign matter.

Conventionally, the process of polishing the roller surface has been carried out by an operator holding a grindstone and sequentially pressing it against the rotating roller surface. However, the polishing process using such a grindstone is very time-consuming and has the problem that the load on the grindstone is not uniform, resulting in unevenness on the roller surface.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a roller polishing device that has good workability and is capable of uniformly polishing the roller surface.

(Means for Solving the Problems) In order to solve the above problems, according to the roller polishing device of the present invention, an abrasive material for polishing the roller is disposed on the outside of the bottom surface of the casing via a buffer material. a polishing unit; a frame housing the at least one polishing unit and fixed so that the polishing surface of the polishing material is exposed from the lower end;
It is characterized by comprising a locking part that locks a cable-shaped body for pulling the frame, and is placed on the roller in a pulled state during roller polishing.

(Function) When the roller polishing device is placed on the conveying rollers and the polishing surface of the abrasive material is in close contact with the surface of each roller, the rope-shaped body that is locked to the locking part of the frame of the device Polishing is carried out either in a stationary state or in a state where the entire device is pulled gradually in the opposite direction to the rotational direction of the rollers. At this time, the abrasive material is pressed against the roller surface by the weight of the frame and the polishing unit, and the rollers are The roller surface is polished as it rotates.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows an example of the configuration of the roller polishing device of the present invention,
The roller polishing device 1 includes a frame 2 and a plurality of polishing units 3, for example, three polishing units 3, which are housed side by side in the frame 2 and fixed to mutually opposing side walls 2a and 2b of the frame 2 by bolts 6.
, a locking part 4 fixed to one side wall 2c of the frame body 2, and a cable-shaped body 5 which is locked to the locking part 4 and is used to pull the roller polishing device 1.

FIG. 2 shows the details of this polishing unit 3. The polishing unit 3 consists of a folded-bottomed housing 10, a cushioning material 11 such as a sponge attached from the bottom 10a of the housing to both sides 10b and 10c, and sandpaper. It consists of abrasive materials 12 such as, and holding plates 13 and 14 for fixing these cushioning materials 11 and abrasive materials 12 to the housing 10. Side surfaces 10b and 10c of the housing IO.

Holes 10b', 1Ocl, 12' for bolt insertion are provided at both ends of the buffer material 11, the abrasive material 12, and the holding plate 13.14, respectively.
.
Place the presser plates 13 and 14 in close contact with the sides 10b and 10c of O, respectively, and apply the presser plates 13 and 14 from the outside.
Bolts 15 are inserted through c11', 12°, 13°, and 14' and fixed with nuts (not shown). Also, the housing l
Screw holes 10d'' and 1 for fixing this housing 10 to the frame body 2 with bolts 6 are provided in the remaining side surfaces 10d and 10e of O.
0e' is formed.

FIG. 3 shows the roller polishing device l placed on the conveying roller 20, and shows the abrasive material 12 of each polishing unit 3.
The polishing surface of is exposed downward from the lower end of the frame 2, and is in close contact with the surface of each roller 20 due to the weight of the entire device. If the weight of the entire roller polishing device is excessive,
There is a problem that the roller 20 does not rotate and the entire surface of the roller 20 cannot be polished.On the other hand, if the entire polishing device l is too light, it will slip and the degree of adhesion between the polishing material 12 and the surface of the roller 20 will be low and it will not be possible to polish the entire surface of the roller 20. A problem arises in that polishing cannot be performed. Therefore, it is necessary to determine the appropriate weight by taking the above points into consideration.

When actually polishing the surface of the conveying roller 20 using such a roller polishing device l, as shown in FIG. The roller polishing device 1 is gradually towed. That is,
While the polishing surface of the polishing material 12 of the polishing unit 3 passes through the roller 20, the entire surface of the roller 20 is polished due to the rotation of the roller. Further, in this roller polishing device 1, the load of the entire device is distributed approximately evenly among the three polishing units 3, so that the surface of each roller 20 is advantageously polished uniformly.

FIG. 4 shows an example of a method for towing the roller polishing device 1, in which a support member 22 for passing the traction cable 5 is attached to one end of the conveyance table 21 on which the roller 20 is disposed, and the The other end of the shaped body 5 is wound around a winch (not shown) to gradually wind it up. Figure 5 shows the support part 2.
2, locking protrusions 22a fixed to both ends of the support member 22 and having a T-shaped cross section are inserted into the notches 21a at both ends of the table 21 and locked. Specifically, as shown in the figure, the opening 2 is formed wide at one end of the notch 21a.
The bottom part 22a of the locking projection 22a is inserted into 1a', and the locking projection 22a is pushed in and locked by sliding it along the narrow groove 21a'' following the opening 21a'' of the notch 21a.

In the above embodiment, the case where three polishing units 3 are used is described, but the number of polishing units 3 is as follows.
It is not limited to this and can be determined as appropriate.

Although the roller polishing device 1 was gradually moved during polishing of the roller, the roller polishing device 1 may not be moved during polishing and the roller polishing device 1 may be pulled by the cable member 5 during polishing.
