Description

The present invention relates to a conductor roll used in an electroplating of a steel plate or an electrolytic surface treatment apparatus for a metal foil, and more particularly to a conductor roll in which a roll part and a shaft part are detachable.

Since the conductor roll is used in a continuous plating line, the roll surface is always in contact with the plating solution and easily corroded, and the steel sheet is easily worn due to contact movement. As a result, the roll surface becomes rough, resulting in poor quality of the steel sheet surface, and the service life of the roll is shortened, resulting in a decrease in production efficiency.
Therefore, the improvement of the conductor roll excellent in corrosion resistance and wear resistance has been proposed conventionally.

A roll portion and a shaft portion that are in contact with the film are detachable.
Hereinafter, each embodiment will be described in detail with reference to the drawings.

  Embodiment 1 of the present invention is shown in FIG. 2 to FIG. 6, toward the inner peripheral surface of one end opening of the roll portion 10 of the conductor roll 2 toward the outside of the roll portion 10 (left side in FIG. 3). An expanding tapered surface 14 is provided.

The shaft portion 20 is inserted into the inside of the roll portion 10 and constitutes a base portion 21 having a screw portion 21a on the surface thereof at a portion protruding outward from the opening portion of the roll portion 10 when mounted. A fixing portion 22 is provided in a portion accommodated in the roll portion 10 on the inner side (right side in FIG. 3) of the base portion 21, and a tapered surface 23 that extends inward is formed on the outer peripheral surface of the fixing portion 22. ing.
Therefore, when the shaft portion 20 is inserted into the roll portion 10, the annular fitting portion 13 whose longitudinal section forms a wedge shape between the tapered surface 14 of the roll portion 10 and the tapered surface 23 of the shaft portion 20. Is formed.
In the figure, reference numerals R1 and R2 denote seal members.

On the other hand, an annular fitting member 25 having a hole 29 in the center is formed. The fitting member 25 forms a tapered surface 26 spreading outward on the outer peripheral surface, and forms a tapered surface 27 spreading inward on the inner peripheral surface. It forms a matching shape.
The fitting member 25 is formed with four screw holes 28 that do not penetrate.

The fitting member 25 and the fitting portion 13 constitute a connecting portion. Although this connection part was provided in the end of the roll part 10 in this embodiment, it can also be provided in both ends.

On the other hand, a pressing member 30 for pressing the fitting member 25 against the fitting portion 13 is configured. The pressing member 30 is an annular member having a smaller diameter than the roll portion 10 and having a hole 32 in the center. A screw portion 32 a is formed on the inner peripheral surface of the hole 32, and the screw portion 32 a is screwed with the screw portion 21 a of the shaft portion 20.
The pressing member 30 is provided with four bolt through holes 31. These bolt through holes 31 are provided at positions facing the screw holes 28 of the pressing member 30 and are used when the fitting member 25 is removed as will be described later.

The operation of this embodiment configured as described above will be described.
First, the case where the roll part 10 and the shaft part 20 are connected is demonstrated.
As shown in FIG. 4, the fitting member 25 is inserted into the fitting portion 13 formed between the roll portion 10 and the shaft portion 20 from the outside (left side in FIG. 4) to the inside (see FIG. 4). .

At this time, the pressing member 30 is screwed into the screw portion 21a of the base portion 21 of the shaft 20, and the surface of the fitting member 25 is pressed to quickly perform the fitting. Since 25 is always pressed by the pressing member 30, there is no possibility that the fitting member 25 is loosened or falls off. It mounts | wears with an apparatus in this state, and the stable electrolytic surface treatment operation | work is performed.

Next, the case where the roll part 10 is removed from the shaft part 20 is demonstrated.
As shown in FIG. 6, the pressing member 30 is moved outward on the screw portion 21 a to create a gap with the fitting member 25.
Next, after attaching the nut 34 to the outer surface of the pressing member 30, the bolt 33 is passed through the bolt through hole 31 of the pressing member 30, and the tip thereof is screwed into the screw hole 28 of the fitting member 25.

  Thereafter, when the nut 34 is rotated, the pressing member 30 is fixed on the screw portion 21a and the bolt 33 does not rotate, so that the bolt 33 moves outward (in the direction of arrow A). Therefore, the fitting member 25 coupled to the bolt 33 also moves in the direction of the arrow A, and comes out of the fitting portion 13 to be in the state of FIG.

  As described above, according to the first embodiment, the fitting member 25 can be quickly fitted to the fitting portion 13 by the pressing member 30 and the fitting state can be reliably maintained, so that the connection between the roll portion 10 and the shaft portion 20 can be achieved. The operation can be facilitated and a stable electrolytic surface treatment operation can be performed.

A second embodiment of the present invention will be described with reference to FIGS.
In the present embodiment, a first annular member 53 having an opening at the center and having a bolt hole 54 around is fixed to one end of the roll portion 50.

A second annular member 55 that contacts the first annular member 53 is formed. A shaft portion 51 extending to the outside of the conductor roll 2 is fixed to the opening of the second annular member 55, and a bolt hole 56 is formed around the shaft portion 51. The first annular member 53 and the second annular member 55 constitute a connection portion. In the drawing, the symbol R3 is a seal member.

When connecting the shaft portion 51 and the roll portion 50, the surface 55 a of the second annular member 55 may be brought into contact with the surface 53 a of the first annular member 53 and then fastened by the bolt 59.
Further, when removing, the work can be easily performed by removing the bolt 59.

As described above, according to the second embodiment, the shaft portion 51 and the roll portion 50 can be easily and reliably connected, and can be easily and quickly removed. Although the connection part of this embodiment was provided in the end of the roll part 50 in this embodiment, it can also be provided in both ends.

A third embodiment of the present invention will be described with reference to FIGS.
A third annular member 63 having an opening at the center and having a threaded portion 65 is fixed to both ends of the roll portion 60. In the drawing, the symbol R3 is a seal member. Although not shown, the third annular member 63 may be provided only at one end of the roll portion 60.

A fourth annular member 64 that contacts the third annular member 63 is formed. A shaft portion 61 extending to the outside of the conductor roll 2 is fixed to the opening of the fourth annular member 64, and a screw portion 66 is formed on the outer peripheral surface. The third annular member 63 and the fourth annular member 64 constitute a connection portion.

When connecting the shaft portion 61 and the roll portion 60, the screw portions 66 and 65 are screwed to each other so that the surface 64 a of the fourth annular member 64 is brought into contact with the surface 63 a of the third annular member 63. Just do it. Also, the removal can be easily performed by releasing the screwed state.

As described above, according to the third embodiment, the shaft portion 61 and the roll portion 60 can be easily and reliably connected, and can be easily and quickly removed.
Further, in the present embodiment, the third annular member 63 is configured at both ends of the roll portion 60, and the screw portions 66 and 65 are respectively reverse screws at both ends of the conductor roll 2, so Loosening can be prevented and stable electrolytic surface treatment can be performed.
