Abstract

(57) [Summary] [Purpose] In a roll surface polishing device for steel plate transport rolls, it is possible to instantly respond to abnormal situations such as scratches, seizures, and dust on the rolls, and extend the life of the polishing cloth. (EN) Provided is a compact roll polishing device which enables partial polishing in the roll width direction which can be performed. [Structure] A sliding tube in which a sliding drive mechanism is connected is loosely fitted to an overhead shaft provided in parallel along the axial direction of a rotating roll, and a polishing cloth is attached to one side of the sliding tube. A steel plate transport roll polishing apparatus having a polishing plate for pressing the roll surface and a polishing plate pressure adjusting mechanism on the other side.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roll surface polishing device for a steel plate transport roll.

[0002]

[Prior art]

 Conventionally, the polishing of the roll surface of a steel sheet transport roll has been performed by moving the polishing cloth stand along the screw shaft or screw shaft provided in the roll axial direction and rotated by an electric motor.

[0003]

[Problems to be solved by the device]

 However, according to such a conventional polishing apparatus, the roll polishing speed is made constant by the length of the screw shaft or the screw shaft and the rotation speed of the electric motor, and the roll polishing width is determined by the length of the screw shaft or the screw shaft. Since the width of the roll is fixed, in the case of a wide roll, the roll polishing time is long and it is not possible to polish the roll width part, so it is possible to immediately respond to abnormal situations such as scratches on the roll, seizure and dust. There was a problem that it could not be done. Furthermore, there is a problem that the guide shaft is indispensable for the movement of the polishing cloth rack due to the structure of the device, which makes the device large in size.

[0004]

[Means for Solving the Problems]

 The present invention solves the above problems, and can instantaneously respond to abnormal situations such as scratches, seizures, and dust on the roll, and allows partial polishing in the roll width direction. Moreover, it is an object of the present invention to provide a compact roll polishing device. The gist of this is that a sliding tube connected to a sliding drive mechanism is loosely fitted to an overhead shaft provided parallel to the axial direction of a rotating roll, and a polishing cloth is attached to one side of the sliding tube. The roll polishing apparatus has a polishing plate for pressing on the surface of the roll and a polishing plate pressure adjusting mechanism on the other side.

Embodiments and Operations The present invention will be described in detail below with reference to the drawings.

The drawings illustrate one embodiment of the present invention.

In FIG. 1, 1 is a steel plate to be transported, and 2 is a transport (or guide) roll. Reference numeral 3 is a bearing of the transport roll 2. That is, the steel plate 1 is transported by the transport roll 2. Reference numeral 4 denotes an overhead shaft, which is provided in parallel along the axial direction of the rotating transport roll 2. A sliding tube 6 having a sliding drive source 5 directly or indirectly connected thereto is loosely fitted on the gantry shaft 4. A cylinder and a rack and pinion mechanism connected to the rotary drive source are used as the slide drive source 5. A polishing plate 8 is provided on one side of the sliding tube 6 for attaching a polishing cloth 7 to press against the surface of the transport roll 2, and a pressure adjusting mechanism 9 for the polishing plate 8 is provided on the other side. The pressure adjusting mechanism 9 drives the polishing plate 8 so that it can be easily attached to and detached from the surface of the transport roll 2. A weight balance mechanism as shown in the figure may be provided, or a pressure adjusting mechanism such as a cylinder is provided. May be. Reference numeral 10 is a fine pressure adjustment plate, which is provided if necessary. The bottom of the pressure fine movement adjusting plate 10 is notched so as to control the vertical movement width of the pressure adjusting mechanism 9, adjust the pressing force of the polishing plate 8, and select the polishing surface of the transport roll 2. A sliding arm 11 that moves in the axial direction is provided.

Therefore, according to the present invention, the sliding drive source 5 and the pressure adjusting mechanism 9 are driven to polish the polishing plate 8 on the polishing surface of the transport roll 2 which rotates due to surface defects such as scratches and baking. After the cloth 7 is brought into contact with the slide arm 11 and the pressing fine movement adjusting plate 10 is moved to finely adjust the pressing force of the polishing plate 8, the surface flaws are removed, and then these reverse operations are performed to retract the polishing plate 8 .

[0009]

[Effect of device]

 As described above, according to the present invention, partial polishing can be performed in the width direction of the roll, and it is possible to instantaneously deal with abnormal situations such as scratches, seizure, and dust on the roll. Further, since the polishing cloth is moved in the roll axis direction by sliding it on the slide guide, the polishing cloth stand holding guide is not required, and the size can be made compact, and the production cost can be reduced (1/3 of the conventional product). Further, since the constituent devices are all mechanically configured, there are advantages that the moving speed of the polishing cloth in the roll axis direction can be easily changed, and that the polishing cloth can be used even in a bad environment.
