BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a side view showing an example of a rubber lining roll according to the present invention with its main part cut away.
In this figure, the rubber lining roll l includes a roll body 2 having a columnar outer peripheral surface 2a and a cylindrical rubber lining 3 attached to the outer peripheral surface 2a. Are divided into a plurality of annular bodies 4 having a predetermined length, and both end shaft portions 5 are rotatably supported by bearing devices 6.

FIG. 2 shows an example in which an annular body 4 is intermittently deposited along the central axis a on the cylindrical outer peripheral surface 2a as another example of the lining roll according to the present invention.
Hereinafter, for convenience, an example shown in FIG. 2 in which the annular body 4 is intermittently attached to the outer peripheral surface 2a will be described.
As shown in FIG. 3, the annular body 4 includes a pair of semi-cylindrical rubber lining units 4 </ b> A and 4 </ b> B, a connecting member 7 that connects the individual units 4 </ b> A and 4 </ b> B in an annular shape, and the connecting member 7. And a rubber plug 16 (FIG. 4) for closing the cutout portion 11a.

The goose lining alone 4A, 4B includes a semi-cylindrical metal base member 10, a rubber layer 11 attached to the outer peripheral surface of the base member 10, and the goose layer 11 at each butted end 4a. A plurality of notches 11a formed at predetermined intervals along the central axis a and screw holes 12 formed in the exposed portion of the base member 10 corresponding to the notches 11a.
The connecting member 7 includes a plurality of screw bodies 13 that are screwed into the screw holes 12 of the base member 10, and a connecting piece 14 that is spanned between the butted ends 4 a and fixed to the screw body 13. It is configured.

Next, the disassembling / assembling work of the above configuration will be described.
First, in FIG. 2, when damage occurs in a predetermined portion of the plurality of annular bodies 4 attached to the outer peripheral surface of the rubber lining roll 1, only the damaged annular body 4 is removed from the roll body 2, and a new An annular body 4 is applied.

Hereinafter, the deposition work will be described.
As shown in FIG. 3, a new pair of rubber linings 4A and 4B are annularly arranged opposite to the outer peripheral surface 2a of the roll body 2, and the connecting piece 14 is fitted into the notch 11a of the ridge layer 11 At the same time, a plurality of screw bodies 13 are inserted into the mounting holes 14a of the connecting pieces 14 and the screw bodies 13 are screwed into the screw holes 12 of the base members 6 to connect and roll as shown in FIG. The outer peripheral surface 2a of the main body 2 can be annularly attached.

FIG. 4 is a perspective view showing an example for achieving the easy deposition work.
First, as shown in the figure, a one-touch lock type fastening band 15 having a fastening bracket 15a is attached to the center of a pair of rubber lining pieces 4A and 4B, and both the pieces 4A and 4B are arranged in an annular shape. After the installation, both sides of the band 15 in the direction of the central axis a are locally connected by the connecting member 7.
Next, the mounting position of the band 15 is changed, the other main parts are connected and fixed in a similar manner, and then the fastening band 15 is removed, so that, for example, connecting pieces are connected to all the notches 11a at three places. 14 is attached to complete the connection of the annular body 4.

Finally, a rubber plug 16 is fitted into the notch 11a, and the joint surface is fixed with an adhesive 18 as shown in FIG. 5, thereby repairing local damage in the new rubber lining roll 1. Regeneration can be achieved.
In addition, as shown in FIG. 3, the buffer sheet 17 is stuck on the inner peripheral surface 10b of the base member 10, and the buffer sheet 17 is inserted between the base member 10 and the roll body 2. A rubber lining roll that is firm and stable can be provided.

Therefore, according to the above configuration, the outer peripheral surface of the rubber lining roll can be locally repaired and reused, and when repairing the outer peripheral surface of these rolls, the repair is performed without removing each roll from the conveying device individually. Regeneration can be accomplished very easily and inexpensively.
In addition, by connecting the rubber lining units 4A and 4B with the connecting member 7, the individual units 4A and 4B can be formed in substantially the same shape by vertically dividing the cylindrical member, thereby making it possible to take material without waste. Can be achieved.

Furthermore, by inserting the buffer sheet 17 between the base member 10 and the roll body 2, a firm and stable rubber lining roll can be provided.
As shown in FIG. 1, the annular body 3 may be continuously applied to the outer peripheral surface 2a of the roll body 2 along the axis a, but as shown in FIG. By intermittently attaching the annular body 4 to the outer peripheral surface 2a of the roll body 2 along the axis a, the number of constituent members can be reduced, and the repairing and regenerating work can be made easier and less expensive.

FIG. 6 is a schematic exploded front view showing still another example of the rubber lining roll 1 according to the present invention.
In the figure, semi-cylindrical rubber linings 4A and 4B are composed of a semi-cylindrical metal base member 10, a rubber layer 11 deposited on the outer peripheral surface of the base member 10, and each butted end 4a. A protruding piece 4b protruding on one side, a recessed piece 4c protruding on the other side, a screw hole 4d formed on the protruding piece 4b and an insertion hole 4e formed on the recessed piece 4c, and an insertion hole 4e There are provided through holes 4f formed in the rubber layer 11 so as to face each other, and a plurality of screw bodies 13 inserted into the holes 4f and 4e and screwed into the screw holes 4d.

In the above-described configuration, a new pair of rubber linings 4A and 4B are annularly disposed opposite to the outer peripheral surface 2a of the roll body 2, and the protruding piece 4b protruding from one of the butted ends 4a is provided on the other side. The outer peripheral surface 2a of the roll main body 2 is fitted to the concave piece 4c and the means 4A and 4B are both substantially the same as the fastening band 15 described in the embodiment of FIG. 4 as shown in FIG. The threaded body 13 is inserted into the holes 4f and 4e and screwed into the threaded hole 4d to connect the single bodies 4A and 4B to form the annular body 4.
Finally, the rubber plug 16 is fitted into the through hole 4f of the rubber layer 11, and the fitting surface is joined with the adhesive 18, thereby achieving the regeneration of the new rubber lining roll 1. Almost the same operational effects can be achieved.
