Conventional abrasives such as sandpaper have an abrasive layer applied to the surface of a flexible sheet material, and therefore the abrasive itself is very hard and lacks in flexibility. When the abrasive is mounted on the polishing head via the elastic pad, there is a drawback that a local corner is formed at a curved portion of the abrasive and the surface of the plate-shaped body is damaged at the corner. In addition, since the polishing material lacks flexibility, the polishing material is attached to the lower side of the polishing head via an elastic pad, but the entire abrasive layer side of the polishing material covers the entire surface of the plate-like body. It is very difficult to make uniform contact. Accordingly, there is a problem in that, when the plate-shaped body is deburred, burrs remain on the surface of the plate-shaped body in a portion where the contact between the abrasive layer of the abrasive and the plate-shaped body is poor. Further, conventionally, since the abrasive material wound around the polishing head is pressed and fixed by a screw-type fixing device, there is a disadvantage that handling is very complicated when the abrasive material is replaced. The present invention
In view of such conventional problems, an abrasive material that has good flexibility and can prevent the occurrence of local squaring and the like on the abrasive layer side and can easily and surely polish the polished surface of a body to be polished such as a plate-like body; An object of the present invention is to provide a polishing apparatus.

On the other hand, a certain period of time has passed since the arrival sensor 71 has detected the leading end of the plate 2, and the leading end of the plate 2 is positioned several millimeters to several tens below the polishing head 41 of the polishing means 7. mm, the raising / lowering cylinder 64a is extended by a signal from the control device to lower the polishing head 41, and the polishing motor 41 vibrating by a circular motion in a horizontal plane is lowered by the operation of the drive motor 44. When the drive motor 44 operates, the drive eccentric shaft 47 fixed to the rotation shaft 46 rotates in the Y direction around the axis of the rotation shaft 46, so that the amount of eccentricity between the rotation shaft 46 and the drive eccentric shaft 47 is reduced. Accordingly, the central portion of the polishing head 41 attempts to make a circular motion. However, a driven eccentric shaft 49 having the same eccentricity and the same phase as the drive eccentric shaft 47 is fitted on the left and right of the polishing head 41,
The two driven eccentric shafts 49 are the timing pulley 5 of the tuning means 50.
7, Since it is in an interlocked state via the timing belt 59,
Each of the driven eccentric shafts 49 is rotated synchronously with the drive eccentric shaft 47, and both ends of the polishing head 41 also start a circular motion, and the polishing head 41 is kept parallel to the left and right by the cooperation of these, The abrasive 43 vibrates by circular motion in a horizontal plane while being pressed against the plate-like body 2.

Therefore, since the polishing head 41 is vibrated by the drive motor 44, the drive eccentric shaft 47, the driven eccentric shaft 49 and the tuning means 50, generation of noise when the polishing head 41 is driven is minimized. The structure of the entire vibration mechanism can be simplified, and the vibration mechanism can be manufactured easily and inexpensively. Especially the tuning means
50 is composed of a timing pulley 57 and a timing belt 59 fixed to the support shaft 48, so that the structure is very simple, and at the same time, the operation is smooth with little noise and the like. A phase shift or the like can be reliably prevented. Also, since the tuning means 50 is above the support member 45, the polishing head
41 can be arranged close to the lower side of the support member 45, and the size can be reduced. Further, since the inner space of the timing belt 59 is widened by the guide wheels 58 and the drive motor 44 is disposed therein,
The whole can be miniaturized. When the polishing head 41 vibrates, the abrasive material attached to the polishing head 41 via the elastic pad 42
Since the plate 43 is in contact with the surface of the plate 2, as the plate 2 moves integrally with the conveyor belt 27, the surface of the plate 2 is moved from one end a to the other end by the abrasive 43. Polish sequentially to b. Therefore, the surface of the plate-like body 2 can be polished to an appropriate rough surface to reliably remove burrs.

In particular, since the abrasive 43 has a large number of slits 80 formed obliquely, even if the sheet material 77 has the abrasive layer 78, the rigidity of the entire abrasive 43 is reduced and the flexibility is improved. However, the elastic material 42 does not bend smoothly along the elastic pad 42, and does not become locally angular at the curved portion, so that the adaptability of the abrasive 43 to the elastic pad 42 is greatly improved. Moreover, as described above, the slit 80 side of the belt-shaped portion is in a warped state as shown in FIG. 13, and the surface of the plate-shaped body 2 is polished by the abrasive layer 78 in the warped portion. Burrs can be removed without damaging the surface of the body 2. Also abrasive material 43
Slits 80 are formed diagonally, and adjacent slits 80
The width in the left-right direction between one end side a and the other end side b in the width direction is reduced, or the one end side a and the other end side b in the width direction between the adjacent slits 80 overlap in the left-right direction. Therefore, even if the amount of vibration in the horizontal direction of the polishing head 41 is reduced,
The entire area of the plate-like body 2 conveyed by the conveyor belt 27 can be reliably polished. Moreover, since the slits 80 of the abrasive 43 are reversed on the left and right sides of the approximate center, the plate-like body 2 moves in the left and right directions during polishing, despite the slits 80 being oblique. The displacement can be prevented.

When the arrival sensor 71 detects the rear end of the plate 2, a certain period of time has passed from the detection point and the plate 2 has been detected.
After the rear end side passes below the polishing head 41, the elevating cylinder 64a contracts and the polishing head 41 rises, and the deburring operation of one plate-like body 2 ends. Note that the plate-like body 2 that has passed through the conveying means 3 is conveyed to the next step via the conveyor 84. When the abrasive 43 is worn, the polishing means 7
