Each work 4, 5 is polished by a single polishing unit 6 arranged on one side (in the present embodiment, the back side of the drawing). The polishing unit 6 is movable in the length direction of the works 4, 5, that is, in the left-right direction in the drawing.

The polishing heads 7 and 8 provided above and below the polishing unit 6 are adapted to press the polishing tapes, which will be described below, wound around the polishing units 6 to the side surfaces of the works 4 and 5, respectively. It is wound on a common winding roll 9 provided at the bottom of the unit 6.

The work pieces 4 and 5 are supported on the support stays 2 and 3 rotatably in the vertical direction with a space therebetween.
Both ends are detachably supported by 0 and 11 and centering shafts 12 and 13.

A belt 16 is wound around a driven pulley 14 provided on the main shaft 10 and a drive pulley 15 provided on the main shaft 11, and a motor 17 which is a common power source
The works 4 and 5 can be simultaneously rotated at a speed of, for example, about 300 to 1800 rpm. However, if the driven pulley 14 and the drive pulley 15 have different diameters, the works 4 and 5 can be rotated at different speeds.

The centering shafts 12 and 13 are respectively connected to the cylinder 19 supported by the support stay 3 via the arm 18, and the cylinder 19 enables the axial movement of the workpieces 4 and 5 when the workpieces 4 and 5 are attached and detached. There is.

As is apparent from FIG. 1, the polishing tape 21 supplied from the supply roll 20 provided on the upper part of the polishing unit 6 has a relatively coarse abrasive grain of about 30 μm, and the polishing head is used. 7 and another supply roll 22 provided below the supply roll 20, and finally is wound up by a winding roll 9 provided below the supply roll 22.

The lower supply roll 22 passes through the polishing head 8 and is wound around the winding roll 9 by the polishing tape 23.
And the polishing tape 23 is 15 μm.
It is composed of relatively fine abrasive grains. These polishing tapes 21 and 23 can be appropriately selected depending on the object to be polished.

As is apparent from FIG. 3, the supply roll 22 is provided with flanges 24 on both sides in the axial direction (in this figure, one of the flanges is removed), and the opposing flange 2 is provided.
The take-up end side of the polishing tape 21 slides on a plurality of slide rollers 25 which are passed between the upper outer peripheral portions of the outer peripheral portion 4 in the circumferential direction at appropriate intervals.

As is apparent from FIG. 2 again, the supply rolls 20 and 22 and the take-up roll 9 are the polishing unit 6
The winding roll 9 is arranged in the vertical direction of the motor 2
Driven by 6. The feeding mechanism for the polishing tapes 21 and 23 including the tension rollers 27 and 28 and the polishing heads 7 and 8 are all incorporated in a single polishing unit 6.

On the back surface of the pedestal 29 of the polishing unit 6, a slider 30 is engaged with a pair of guide rails 31 provided on the table 1 in the length direction of the works 4, 5.
A slide nut 32 provided on the back surface of the pedestal 29 between the guide rails 31 engages around a screw shaft 33 provided in parallel with the guide rail 31, and the screw shaft 33 is normally or reversely rotated by a driving means (not shown). By letting
The polishing unit 6 is movable on one side of the works 4, 5 in the length direction thereof.

Next, the operation of this embodiment will be described. A common motor 3 is used for the workpieces 4 and 5 arranged vertically in two stages.

Thus, the polishing tapes 21 and 23 are brought into pressure contact with each other to polish in the circumferential direction, and at the same time, the polishing unit 6 is moved in the length direction of the works 4 and 5 to polish the entire surfaces of the works 4 and 5.

Therefore, if the time required to polish each work is, for example, 120 seconds, the rough finishing and the finishing are completed at the same time. Therefore, the time required to finish one work by the conventional sequential method is a relatively long time, which is 240 seconds, which is the sum of the required times, and the time for exchanging the polishing tape. , Can be significantly shortened.

Moreover, the drive source for each work 4 and 5 need only be one common motor 17, and each polishing tape 21,
Since 23 can be wound by the common winding roll 9,
The number of parts can be reduced and the entire device can be made compact.

Further, the supply rolls 20 and 22 and the take-up roll 9 are arranged in the vertical direction of the polishing unit 6, and the feeding mechanism for the polishing tapes 21 and 23 and the polishing heads 7 and 8 are integrated. By incorporating it in the polishing unit 6 and arranging it on one side of the works 4 and 5, the entire apparatus can be made more compact, and work can be performed only on one side of the works 4 and 5, that is, on the front side in FIG. Therefore, workability is also improved.
